Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 to 9, the refrigerator dispenser is schematically shown to include a pre-buried housing 1, an outer cover plate 2, a dispenser body 3, and a driving mechanism 4.

In the embodiment of the application, the embedded casing 1 is installed in the door 201 of the refrigerator, that is, the embedded casing 1 is fixedly installed inside the door 201 of the refrigerator, and does not move back and forth or left and right relative to the door 201.

As will be understood by those skilled in the art, since the foam layer is disposed inside the door 201, the embedded casing 1 will not move due to the foam layer disposed around the embedded casing 1 after the embedded casing 1 is disposed inside the door 201.

The outer cover plate 2 is arranged on the door body 201 and located on the outer side of the door body 201, wherein the upper end of the outer cover plate 2 is hinged to the door body 201, and the lower end of the outer cover plate 2 can move close to and away from the outer side face of the door body 201.

The shape of the outer cover 2 is not limited to the rectangular shape shown in the drawings, but may be a square, circle, oval or the like.

The dispenser body 3 includes a folding ice channel 31, an ice inlet end 311 of the folding ice channel 31 is installed on the embedded casing 1, and an outer end 312 of the folding ice channel 31 is installed on the outer cover plate 2. It is easy to understand that one end of the outer cover plate 2 is hinged to the door body 201, the other end can move closer to and away from the outer side surface of the door body 201, and the embedded casing 1 is fixedly arranged inside the door body 201 and remains stationary. Thus, once the outer cover plate 2 is driven by external force, the outer cover plate can move close to and away from the embedded shell 1.

The driving mechanism 4 is connected to the outer cover plate 2, wherein the outer cover plate 2 is driven to rotate by the rotation of the driving mechanism 4, and the outer end 312 of the folded ice channel 31 is driven to move toward and away from the ice inlet end 311 of the folded ice channel 31 by the rotation of the outer cover plate 2, so that the folded ice channel 31 is contracted and expanded. Specifically, when the user needs to take ice, the driving mechanism 4 is started, the driving mechanism 4 is moved to drive the outer cover plate 2 to rotate towards the outer side of the door body 201, and the ice inlet end 311 of the folded ice channel 31 and the outer end 312 of the folded ice channel 31 are driven to move away from each other by the rotation (clockwise or counterclockwise rotation) of the outer cover plate 2, so that the folded ice channel 31 is unfolded, and the unfolding is stopped when the folded ice channel 31 is unfolded to the optimal state, and at this time, the driving mechanism 4 stops moving.

On the contrary, after the user finishes taking the ice, the driving mechanism 4 is started again, the driving mechanism 4 moves in the direction opposite to the previous moving direction, so as to drive the outer cover plate 2 to rotate towards the inner side of the door body 201, and the ice inlet end 311 of the folded ice channel 31 and the outer end 312 of the folded ice channel 31 are driven to move close to each other by the rotation (counterclockwise or clockwise rotation) of the outer cover plate 2, so that the folded ice channel 31 contracts, and when the folded ice channel 31 contracts to the optimal state, the contraction is stopped, and at this time, the driving mechanism 4 stops moving again.

The "optimal spread state" means a state in which the inside diameter of the folded ice passage 31 is spread to allow ice cubes or crushed ice to pass smoothly.

The "best retracted state" means that the entire folded ice chute 31 is completely retracted into the door 201 and the inner surface of the outer cover 2 is just completely attached to the outer surface of the door 201. Thus, the purpose of small occupied space is achieved.

In addition, since the folded ice channel 31 is completely located inside the door body 201 in the contracted state, that is, the ice outlet end 313 of the folded ice channel 31 is also located inside the door body 201, the ice outlet end 313 can be effectively prevented from being polluted by dust, bacteria and the like in the environment.

In addition, since the folding ice passage 31 is formed by mutually hinging and folding a plurality of folding plates, the folding ice passage 31 can be accommodated in a small space, the occupied space is small, and in the process that the folding ice passage 31 is frequently opened or folded, the connection mode among the plurality of folding plates forming the folding ice passage 31 is mostly a hinging mode, and adjacent plates are not directly collided in the process of opening or folding, so that the movement noise is often low, the quality of products is greatly improved, and the use comfort of users is enhanced.

It should be noted that, because the folding plates hinged to each other in the folding ice channel 31 of the present application can rotate freely around the hinge axis, compared to the ice channel in the prior art which is formed by overlapping and splicing multiple hard pipes, the refrigerator dispenser of the present application has a simple and compact structure, and can effectively avoid the abrasion between the hard pipes, and on the other hand, greatly reduces the probability of damage to the ice channel.

In one embodiment, the drive mechanism 4 is disposed on the embedded housing 1.

As shown in fig. 4, the lower end of the folded ice chute 31 is schematically shown as the ice outlet end 313. The opening direction of the ice discharge end 313 may be directed downward (see fig. 1 and 2), whereby ice taking may be facilitated.

It should be noted that when the folded ice chute 31 is completely unfolded, the opening in the ice outlet end 313 is completely located on the front side of the door 201 of the refrigerator.

As shown in fig. 6, in a preferred embodiment of the present application, an ice inlet hole 11 is formed in the embedded shell 1. The shape of the ice inlet hole 11 is not limited to only the shape shown in the drawings, but may be square, oval, rectangular, etc. It will be understood by those skilled in the art that the diameter of the ice inlet 11 should be larger than the outer diameter of the largest single ice piece to achieve smooth ice feeding into the folded ice chute 31 and avoid the ice pieces from being blocked at the ice inlet 11.

An ice outlet hole 21 is formed in the outer cover 2, an ice inlet end 311 of the folded ice passage 31 communicates with the ice inlet hole 11, and an ice outlet end 313 of the folded ice passage 31 is disposed at the periphery of the ice outlet hole 21. Thus, ice cubes or crushed ice can be smoothly entered into the folded ice chute 31 from the ice inlet 11 through the ice inlet end 311, and then delivered to the outside of the door 201 of the refrigerator 200 from the ice outlet 21 through the ice outlet end 313 of the folded ice chute 31, so that the user can take the ice.

It will be appreciated by those skilled in the art that the aperture of the ice outlet 21 should also be larger than the outer diameter of the single largest ice piece to ensure a smooth delivery of the ice pieces or crushed ice.

As shown in fig. 4 and 5, in another preferred embodiment of the present application, a bottom plate 22 extending toward the embedded casing 1 is provided on the outer cover plate 2, and the ice outlet 21 is formed on the bottom plate 22. It should be noted that the bottom plate 22 and the outer cover plate 2 are of an integral structure. Thus, the use of screws or rivets to fasten the base plate 22 is eliminated, thereby also saving installation time of the base plate 22.

Wherein, when the folding ice duct 31 is in the unfolded state, the ice outlet 21 is located at the front side of the door body 201 of the refrigerator 200. Therefore, the volume of the door body 201 occupied by avoiding the ice receiving container is eliminated, so that the convex hull on the inner container of the door body 201 is reduced, and the effective volume in the refrigerator 200 is increased.

It should be noted that, in order to avoid the ice container, a concave surface is usually formed on the outer side surface of the door 201 of the conventional refrigerator door, however, since the size of the dispenser in the prior art is fixed, in order to smoothly accommodate the dispenser, a corresponding convex surface (facing the inside of the refrigerator) needs to be formed on the inner container of the door 201, however, the existence of the convex surface will inevitably affect the installation of the bottle frame, and thus, the space utilization rate inside the refrigerator is also reduced.

The ice outlet 21 in the application is completely positioned at the front side of the door body 201, so that the problem of avoiding an ice container is solved, and the condition of convex hulls generated on the inner container of the door body 201 is effectively reduced, so that the space utilization rate inside the refrigerator 200 is effectively improved.

As shown in fig. 4 to 8, in another embodiment, the folded ice passage 31 includes a first folding plate group 20, a second folding plate group 30 disposed at a left side of the first folding plate group 20, and a third folding plate group 40 disposed at a right side of the first folding plate group 20. The second folding plate set 30 and the third folding plate set 40 are oppositely disposed.

As shown in fig. 6, in order to further optimize the first folding plate set 20 in the above technical solution, on the basis of the above technical solution, the first folding plate set 20 includes a first folding plate 201 disposed below the ice inlet 11 and a second folding plate 202 hinged to the first folding plate 201, wherein an end of the second folding plate 202 away from the first folding plate 201 is hinged to a front end of the bottom plate 22. That is, the second folding plate 202 is hinged to the first folding plate 201 through a shaft hole, and both can rotate around the matching axis.

Similarly, the end of the second folding plate 202 away from the first folding plate 201 is hinged to the bottom plate 22 via a shaft hole, and the second folding plate and the bottom plate can rotate around a matching axis.

As shown in fig. 6, it is also schematically shown that the refrigerator dispenser further includes a left protector 5 disposed at a left side of the ice inlet hole 11 and a right protector 6 disposed at a right side of the ice inlet hole 11.

As shown in fig. 4 and 6, in a preferred embodiment, the second folding plate group 30 includes a third folding plate 301 hinged to the left guard plate 5 and a fourth folding plate 302 hinged to the third folding plate 301, wherein an end of the fourth folding plate 302 remote from the third folding plate 301 is hinged to the left side of the outer lid panel 2. That is, the third folding plate 301 and the left protection plate 5 are in hinged fit with each other through a shaft hole, and both can rotate around the fit axis.

Similarly, the third folding plate 301 and the fourth folding plate 302 are also in hinged fit with each other via shaft holes, and both can rotate around the axis of fit.

The fourth folding plate 302 is hinged and matched with the left side of the outer cover plate 2 through a pin hole, and the fourth folding plate 302 can freely rotate relative to the outer cover plate 2.

In another preferred embodiment, the third folded plate group 40 comprises a fifth folded plate 401 hinged to the right guard plate 6 and a sixth folded plate 402 hinged to the fifth folded plate 401, wherein an end of the sixth folded plate 402 remote from the fifth folded plate 401 is hinged to the right side of the outer cover plate 2. That is, the fifth folding plate 401 and the right protection plate 6 are hinged and matched through a shaft hole, and both can rotate around a hinge axis.

Similarly, the sixth folding plate 402 is hinged to the shaft hole of the fifth folding plate 401, and the sixth folding plate and the fifth folding plate can rotate around the hinge axis.

The sixth folding plate 402 is hinged to the outer cover plate 2 at the right side by pin holes, and the sixth folding plate 402 can rotate freely relative to the outer cover plate 2.

As shown in fig. 6, in another preferred embodiment of the present application, a first transfer structure 7 is disposed on an end of the fourth folding plate 302 away from the third folding plate 301, and a second transfer structure 50 is disposed on an end of the sixth folding plate 402 away from the fifth folding plate 401.

A connecting plate 60 is arranged on the side of the outer cover plate 2 facing the embedded shell 1. The surface of the connecting plate 60 facing the outer cover plate 2 is tightly attached to the surface of the outer cover plate 2 facing the connecting plate 60.

As shown in fig. 5, a first sliding slot (not shown) is formed at the left side of the connecting plate 60, and a second sliding slot 602 is formed at the right side of the connecting plate 60, wherein the first adaptor structure 7 is movably disposed in the first sliding slot, and the second adaptor structure 50 is movably disposed in the second sliding slot 602. It should be noted that the first adapter structure 7 can slide in the first sliding groove, and can rotate circumferentially around its center line.

Similarly, the second adapter structure 50 can slide in the second sliding groove 602, and can rotate circumferentially around its center line.

It should be noted that the first switching structure 7 and the second switching structure 50 each include a nest embedded in the folding plate, a connecting column disposed on the nest, and a rotating block disposed on the connecting column and capable of rotating circumferentially relative to the connecting column, and each rotating block is embedded in a corresponding sliding slot.

It can be seen that the folding ice channels 31 of the present application are each composed of a plurality of folding plates hinged to each other, so that, under the driving action of the driving mechanism 4, each folding plate can move freely and flexibly to achieve the contraction and expansion of the folding ice channels 31, and, in the process of contraction or expansion, adjacent folding plates do not collide with each other.

As shown in fig. 3 and 9, in a preferred embodiment of the present application, the driving mechanism 4 includes a driving motor 41, a first transmission link 42 connected to an output end of the driving motor 41, a second transmission link 43 connected to the first transmission link 42, and a third transmission link 44 connected to the second transmission link 43, wherein the first transmission link 42 and the third transmission link 44 are arranged in parallel. Both ends of the second transmission link 43 are movably connected to the lower ends of the first transmission link 42 and the third transmission link 44, respectively.

In another preferred embodiment of the present application, the driving mechanism 4 further includes a transverse rotation shaft 45, and a first link 46 and a second link 47 respectively disposed at intervals along an axial direction of the transverse rotation shaft 45, wherein the first link 46, the second link 47 and the third transmission link 44 are fixedly connected to the transverse rotation shaft 45.

As shown in fig. 3 and 9, in a preferred embodiment of the present application, the first link 46 and the second link 47 are fixedly connected to the outer cover 2. Specifically, a first screw hole is formed in each of the first connecting rod 46 and the second connecting rod 47, a second screw hole is formed in each of the outer cover plate 2, and the first screw holes in the first connecting rod 46 and the second connecting rod 47 are respectively and correspondingly communicated with the corresponding second screw holes, and then the corresponding screws or rivets are sequentially passed through the first screw holes and the second screw holes correspondingly communicated therewith, and then the screws or rivets are screwed, so that the outer cover plate 2 can be fixedly connected with the first connecting rod 46 and the second connecting rod 47.

Specifically, when a user needs to take ice, the driving motor 41 is started, the first transmission connecting rod 42 is driven to rotate towards the outer side of the door body 201 of the refrigerator through rotation (clockwise or counterclockwise) of the output end of the driving motor 41, the second transmission connecting rod 43 is driven to synchronously rotate along with the rotation of the first transmission connecting rod 42, namely, the second transmission connecting rod 43 rotates towards the outer side of the door body 201 of the refrigerator, the third transmission connecting rod 44 is driven to synchronously rotate along with the rotation of the second transmission connecting rod 43, and the transverse rotating shaft 45 is driven to circumferentially rotate (counterclockwise) around the central axis of the transverse rotating shaft through rotation of the third transmission connecting rod 44.

Through the circumferential rotation of the transverse rotating shaft 45, the first connecting rod 46 and the second connecting rod 47 can be driven to swing towards the outer side of the door body 201 of the refrigerator, and meanwhile, the outer cover plate 2 can be driven to rotate towards the outer side of the door body 201 of the refrigerator, so that the ice inlet end 311 and the outer end 312 of the folding ice channel 31 are gradually separated, and the folding ice channel 31 is unfolded.

It will be understood by those skilled in the art that when the user finishes picking the ice, the moving direction between the components of the driving mechanism 4 is opposite to the moving direction between the components of the driving mechanism 4 when picking the ice, and for the sake of brevity, the detailed description is omitted here.

As shown in fig. 9, the driving mechanism 4 is also schematically shown to further include a mounting seat 48, and the mounting seat 48 is disposed between the first link 46 and the second link 47.

The first link 46 is hinged to the left side of the mounting base 48, and the second link 47 is hinged to the right side of the mounting base 48. It should be noted that the mounting seat 48 can be hinged with the first link 46 and the second link 47 by screws or rivets, respectively.

As shown in fig. 3, in a preferred embodiment of the present application, the driving mechanism 4 further includes a supporting plate 49 connected to the mounting seat 48, and the supporting plate 49 is used for installing a sealing door (not shown) capable of blocking or opening the ice inlet 11. The sealing door may be fastened to the support plate 49 by means of snaps, screws or rivets, etc. It should be noted that, after the user finishes taking the ice, the supporting plate 49 may be driven by the driving mechanism 4 to drive the sealing door to move toward the ice inlet 11, and the driving mechanism 4 stops moving until the sealing door completely blocks the ice inlet.

After the sealing door blocks the ice inlet hole 11, the heat preservation effect can be achieved, and therefore the purpose of effectively reducing the loss of cold energy is achieved.

As shown in fig. 1 and 2, in a preferred embodiment of the present application, the refrigerator dispenser further includes a micro switch assembly 8, and the micro switch assembly 8 includes a switch support 81 connected to the embedded casing 1, and a micro switch 82 disposed on the switch support 81.

Specifically, by pressing the push plate 83, the push plate 83 will move toward the micro switch 82, until the push plate 83 contacts the micro switch 82 and presses the micro switch 82 to the maximum position, and then the push plate 83 stops being pressed, at which time the signal of the micro switch 82 is triggered, and the folded ice channel 31 is in the unfolded state and starts to discharge ice.

In another preferred embodiment of the present application, the refrigerator dispenser further comprises a display control panel 9 disposed on the outer cover 2, and an ice-fetching key (not shown) is disposed on the display control panel 9, wherein ice cubes or crushed ice are discharged through the ice discharge end 313 after the ice-fetching key is clicked and the push plate 83 is pushed to touch the microswitch 82. Specifically, when the user needs to take ice, the user needs to select an ice taking mode (ice making/ice crushing) on the display control panel 9 and click a corresponding ice taking key, after the selection is completed, the control panel (not shown in the figure) receives a signal and sends a signal to the driving motor 41, the driving motor 41 drives the transmission structure to move, and the folding ice channel 31 is unfolded.

When the folded ice channel 31 is unfolded to a specified position (completely unfolded state), the driving motor 41 stops working, a user needs to apply an external force to the push plate 83, so that the micro switch 82 acts, the control board sends a signal to the ice motor (not shown in the figure), ice cubes or crushed ice are sent out from the ice outlet hole 21 after passing through the ice outlet end 313 from the inside of the folded ice channel 31, at this time, the external force is released, the push plate 83 is separated from the micro switch 82, the micro switch 82 is disconnected, the ice outlet motor stops working, and ice outlet stops.

After a period of time delay, the driving motor 41 rotates reversely to drive the transmission structure to move, the folded ice channel 31 contracts until the folded ice channel contracts to a specified position (inside the door body 201), and the driving motor 41 stops working again to wait for a next action trigger signal.

As shown in fig. 1 and 2, in another preferred embodiment of the present application, a water outlet 12 is configured on the embedded casing 1, and the water outlet 12 is fixed on a door 201 of a refrigerator 200. Specifically, the water outlet 12 is fixed on the door 201, and the water pipe connected to the water outlet 12 is relatively static, i.e. does not rotate along with the contraction and expansion of the folding ice channel 3, so that the situation that residual water at the water outlet 12 drips is effectively avoided.

The water outlet 12 and the ice outlet 21 are arranged up and down. Thus, the user can distinguish the ice or water more conveniently.

The water outlet 12 is disposed at one side of the ice outlet end 313. The opening of the water outlet 12 faces downward, which is convenient for users to get water. Specifically, when a user needs to take water, the control board sends an action signal to the driving motor 41, so that the rotary water receiving tray 202a is opened as described below, the folding ice channel 31 is still in a closed state at the moment, after the user finishes taking water, the push plate 83 is separated from the micro switch 82, the micro switch 82 is turned off, the water path is closed, but the rotary water receiving tray 202a is turned off with a delay at the moment so as to receive residual water possibly appearing at the water outlet 12.

It should be noted that the water outlet 12 and the ice outlet 313 of the folded ice channel 31 are not of the same diameter, but cannot discharge ice when the user is getting water, or cannot discharge water when the user is getting ice.

As shown in fig. 10, according to a second aspect of the present application, there is also provided a refrigerator, which includes a cabinet 203, a door 201 pivotally connected to the cabinet 203, and the refrigerator dispenser provided on the door 201.

It should be noted that the refrigerator 200 may have a single door, a double door, or a triple door.

In another embodiment, the refrigerator further comprises a rotary water receiving tray 202a arranged on the door body 201, and the rotary water receiving tray 202a is positioned right below the water outlet 12. It should be noted that one end of the rotating water pan 202a is hinged to the door 201, and the other end is in a free state, that is, the rotating water pan can move closer to and away from the door 201 according to actual needs.

That is, when the user does not take water, the rotary water pan 202a is often accommodated inside the door body 201, and thus, the function of reducing the occupied external space can be also achieved.

On the contrary, when the user needs to take water, the control panel controls the rotary water pan 202a to extend out of the door body 201 to receive the residual water at the water outlet 12, so as to avoid the situation that the residual water drops on the ground, so that the old or the young slips.

It should be noted that all words relating to "front", "rear", "left" and "right" are used in the description of the present figure orientation.

In summary, when a user needs to take ice, the driving mechanism 4 is started, the driving mechanism 4 is moved to drive the outer cover plate 2 to rotate towards the outer side of the door 201, and the ice inlet end 311 of the folded ice channel 31 and the outer end 312 of the folded ice channel 31 are driven to move away from each other by the rotation (clockwise or counterclockwise rotation) of the outer cover plate 2, so that the folded ice channel 31 is unfolded, and when the folded ice channel 31 is unfolded to an optimal state, the unfolding is stopped, and at this time, the driving mechanism 4 stops moving.

In addition, because the folding ice channel 31 is formed by mutually hinging and folding a plurality of folding plates, the folding ice channel 31 can be accommodated in a small space, the occupied space is small, in the process that the folding ice channel 31 is frequently opened or folded, the connection mode among the folding plates forming the folding ice channel 31 is mostly a hinging mode, and adjacent plates cannot be directly collided in the process of opening or folding, so the movement noise is often low, the quality of products is greatly improved, and the use comfort of users is enhanced.

It should be noted that, since the hinged plates in the folding ice channel 31 of the present application can freely rotate around the hinge axis, compared to the ice channel in the prior art which is formed by overlapping and splicing multiple hard pipes, the refrigerator dispenser of the present application has a simple and compact structure, and can effectively avoid the abrasion between the hard pipes, and on the other hand, greatly reduces the probability of the damage to the ice channel.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
