In the case of the bathtub, the number of driving can be measured in the same way according to the output of the second quantity sensor or the driving instruction signal of the manipulator 31.

In addition, the storage means 35 is provided with a storage place for storing and storing, as predetermined package data, data that can constitute maintenance information as shown in FIG.

The operation means 31 which instructs the data input to the storage means 35 or the display of the data is generally used in a mode of operation of the manipulator 31 which is used to give instructions for setting use conditions when the user uses the hot water supply device. To change to maintenance mode.

As a matter of course, an operating device dedicated to a supplier used by a specialist who performs maintenance inspection of the hot water supply device connected to the controller 30 as necessary may be used as the operation means.

3 is an external view showing an example of the manipulator 31. The manipulator 31 includes a switch 38 and a display 39. The switch section 38 includes two " cold " and " hot " switches 41 and 42, which are used to set hot water temperature for hot water supply and bathtub, " full automatic " switch 43 for instructing automatic operation, and operation. At the time of correction of the "operation" switch 44 to instruct, the "reservation operation" switch 45 to instruct the reserve operation, the "reservation setting" switch 46 to set the reservation time in the case of instructing the reservation operation and the time A new "clock setting" switch 47 is provided, and further, "hour" and "minute" switches 48 and 49 used for setting the time are provided.

The display unit 39 includes at least a hot water set temperature display unit A, a bath set temperature display unit B, and a set time display unit C. When the contractor accesses the maintenance information processing device using the manipulator 31, a secret switch which is not normally used by a general user is set and the manipulator 31 approaches the maintenance information storage device according to the switch operation. The operation means 31 is changed to the maintenance mode that can be performed.

For example, the manipulator 31 is changed from the setting instruction mode of the controller 30 to the maintenance mode by simultaneously pressing the two switches 44 and 41 at " operation " By such an operation, each of the switches 41 to 49 of the switch unit 38 of the manipulator 31 is a switch which displays the input information of the storage means 35 or instructs the input. A switch for instructing data display is displayed by displaying information for specifying data for calling data in 35). The display unit 39 is, for example, a display unit A of the monitor number at which the hot water set temperature display unit A sets the cumulative data, and the bath set temperature display unit B is the display unit B of the part code as information for specifying the replacement product. In addition, the set time display section C changes to the display section C of the accumulated data.

In order to easily input replacement parts, codes are set as shown in the table below for the components of the hot water supply device that may be replaced as information specifying the replaced components when the hot water supply device is repaired.

For example, the cumulative input data for replacing the blower blower motor is only the cumulative data of monitor numbers 01, 02, 03, and 04. The cumulative data of the combustion part of the bath combustor of the monitor number 03 is not directly related. There is no need to remember. These can be set suitably for every component to be replaced. In accordance with the input operation by the above operation means 31, all the data constituting the maintenance information shown in FIG. 4 are stored in the storage means 35. As shown in FIG.

During maintenance inspection, when the operator changes the operator 31 to the maintenance mode and presses the "hot" switch 42, which is the monitor number display switch, the monitor number display section A specifies the cumulative combustion time of the hot water burner 3. The monitor number 01 is displayed, and the cumulative combustion time from the start time of use of the hot water burning unit corresponding to 01 is displayed in the cumulative data display unit C. Each time the monitor number display switch 42 is pressed, the monitor number changes to 02, 03, 04, and 01 in turn, and each time the cumulative data from the start of use corresponding to the monitor number is displayed in sequence.

When the cumulative data from the start of use is displayed by the monitor number display switch 42, the part code display section B displays the part code input to the storage means 35. In the case of no replacement parts, 00 is displayed in the part code display part. In the case where several parts are already replaced, the part code display part (B) displays the part code with the smallest accumulated data. . In this state, when the supplier presses the "reservation operation" switch 45 set in the part code call switch, the cumulative data and replacement code call switch of the corresponding replacement part specified in the monitor number displayed on the monitor number display section (A) are displayed. (45) The cumulative data display part C displays the cumulative data after replacing parts obtained by the calculation means of the control circuit unit 33 from the cumulative data from the start of use for operation.

Furthermore, each time the part code call switch 45 is pressed, the part code is called from the storage means 35 to the part code display section B in the order of the numerical value of the accumulated data at the time of replacement being small, that is, the order in which the parts are replaced. The cumulative data after parts replacement is displayed on the cumulative data display section C together with the code. When the cumulative data of the part codes displayed by the part code call switch 45 is selected, the monitor number display part A is changed by the monitor number display switch 42 in this state to correspond to the displayed monitor display part. The accumulated data after parts replacement can be displayed on the accumulated data display section (C). When 00 is called to the part code display section B by the part code call switch 45, the cumulative data value at the time of maintenance check, i.e., the cumulative data at the time of the previous maintenance check and the start of use of the display time The accumulated data after the last maintenance check calculated by the calculating means from the accumulated data is displayed on the accumulated data display section (C).
