Problems solved by technology

When the maintenance display is displayed, the user may judge that the maintenance is possible, but in fact, it has exceeded the use period that can ensure the reliability and safety of the product, so it is difficult to guarantee the reliability and safety.
And, in practice, there are times when it is impossible to manufacture the replacement parts even when repairs are required
Therefore, when the inspection display or the inspection warning is performed again, the user may misunderstand that it can be used for a longer period of time only by the inspection.

no. 1 approach

[0026] First, the configuration of dishwasher 50 in the first embodiment of the present invention will be described.

[0027] figure 1 It is a cross-sectional view of dishwasher 50 according to the first embodiment of the present invention.

[0028] like figure 1 As shown, the dishwasher 50 includes: a housing 1 housed in a kitchen; and a washing tank 4 having an opening 2 above it for receiving tableware 3 for washing. The cleaning tank 4 is connected to the water pipe through the water supply part 5, and water is supplied into the cleaning tank 4 during operation. On the front surface of the casing 1 are disposed an operation unit 6 for turning on and off the power supply, selecting an operation course, and the like, and a display unit 7 for displaying various states.

[0029] In addition, rails 8 are erected in a substantially horizontal direction inside both side surfaces of the casing 1 , and a cleaning tank 4 is provided along the rails 8 so as to be freely withdrawab...

[0078] Next, dishwasher 51 in the second embodiment of the present invention will be described.

[0079] Image 6 It is a cross-sectional view of dishwasher 51 according to the second embodiment of the present invention. exist Image 6 Herein, the same reference numerals are attached to the same constituent elements as those of the dishwasher 50 described in the first embodiment, and description thereof will be omitted.

[0080] Dishwasher 51 differs from dishwasher 50 described in the first embodiment of the present invention in that control unit 31 of control device 34 performs control differently from control unit 21 of dishwasher 50 .

[0081] Figure 7 It is a functional block diagram showing the configuration of control device 34 of dishwasher 51 according to the second embodiment of the present invention.

[0082] like Figure 7 As shown, the control device 34 includes a load driving unit 22 , a storage unit 23 , and a control unit 31 .

[0083] The load driving u...

no. 3 approach

[0123] Next, the dishwasher 52 in the 3rd Embodiment of this invention is demonstrated.

[0124] Figure 10 It is a cross-sectional view of a dishwasher 52 according to a third embodiment of the present invention. exist Figure 10 Herein, the same reference numerals are attached to the same constituent elements as those of the dishwasher 50 described in the first embodiment or the dishwasher 51 described in the second embodiment, and description thereof will be omitted.

[0125] The difference between the dishwasher 52 and the dishwasher 50 described in the first embodiment of the present invention and the dishwasher 51 described in the second embodiment is that the control unit 41 of the control device 44 communicates with the control unit of the dishwasher 50 21 and the control unit 31 of the dishwasher 51 are controlled differently.

[0126] Figure 11 It is a functional block diagram showing the configuration of control device 44 of dishwasher 52 according to the third...

Abstract

There is provided a dishwasher for washing an object to be washed, the dishwasher including an operation unit for inputting an instruction to the dishwasher; a control unit for carrying out an operation control of the dishwasher based on the instruction input by the operation unit; a display unit for displaying an operation status of the dishwasher; and a storage unit for storing information associated with an operation elapsed state, and enabling read and write of the information. The control unit performs a display of an inspection notifying that an inspection timing of the dishwasher is reached by the display unit when determined that an operation time greater than or equal to a first predetermined time has elapsed based on the information associated with the operation elapsed state stored in the storage unit. The display of the inspection is subsequently not performed again regardless of an operation elapsed state of the dishwasher by rewriting the information associated with the operation elapsed state stored in the storage unit at the time of the inspection.

Description

technical field [0001] The present invention relates to a dishwasher for washing objects to be washed, such as tableware, using washing water. Background technique [0002] In general, in a dishwasher, when used for a long period of time, physical or chemical component deterioration is accelerated due to the influence of heating by a heater, washing, or oil rinsed from the object to be washed. Therefore, it is desirable to perform inspections by repair and inspection workers for a predetermined accumulated operating time or the like. [0003] On the other hand, a technique has been proposed in which a memory is used in electrical equipment requiring reliability and safety, the counted operating time is stored in the memory, and a warning and display are automatically performed when the accumulated operating time exceeds a predetermined value. According to this technique, it is possible to promote preventive maintenance by notifying the user of the inspection time (for examp...
