Description of the Related Art As shown in FIG. 5, in a conventional dishwasher / dryer, a tableware basket 19 containing dishes 18 and the like is stored in a predetermined place of the main body, and a detergent is set in a detergent insertion portion, and Close the lid and start operation. When you start driving,
First, the water supply valve 20 operates to supply a predetermined amount of cleaning water 21 to the cleaning tank 22. Then, the washing pump 23 pressurizes the washing water 21 and jets the washing water 21 mixed with the detergent from the washing nozzle 24. Thus, the main washing step is performed. In this main washing step, the heater 25 provided in the washing tank 22 is energized to heat the washing water 21 to a predetermined washing temperature.

The cleaning water 21 containing the dirt washed off from 8 etc. is discharged to the outside of the machine by the drainage pump 26. Subsequently, the cleaning water 21 is newly supplied and jetted again from the cleaning nozzle 24,
A step of rinsing the dishware 18 and the like that are soiled with detergent or residual food (food that has adhered to the dishes as dirt is called residual food) is executed. When this rinsing step is completed, the cleaning water 21 is drained out of the machine again. This rinse step is repeated 3 times in succession. At this time, the residual food is collected in the filter 27 provided in the cleaning tank 22.

る。しかしこの場合は、乾燥工程中に食器１８に供給で
きる熱量が少なくなって、乾燥時間が長くなってしま
い、自動食器洗い乾燥機での食器洗浄時間が非常に長く
なる。However, the above-mentioned conventional dishwasher / dryer has the following problems.
That is, since the heater 25 is exposed in the cleaning tank 22, the resin tableware or the like is placed in the table basket 19 while the cleaning water 21 is being sprayed.
There is a case where it falls off from the nozzle and comes into contact with the heater 25 to be thermally deformed or burnt. In this case, the tableware 18 may be burned or smoked. Further, if the user comes into contact with the heater 25 immediately after the completion of the drying process, there is a possibility that the heater 25 will not be cooled and thus burns. In order to avoid such cases, in the drying process, a control method of repeating the operation cycle in which the energization time of the heater 25 is shortened and the non-energization time is lengthened may be adopted. However, in this case, the amount of heat that can be supplied to the dishes 18 during the drying process is reduced, and the drying time becomes long, and the dishwashing time in the automatic dishwashing dryer becomes extremely long.

め、洗浄不良のまま運転を継続するということになる。In the conventional structure, the heater 25 can heat the cleaning water 21 even if the cleaning water 21 does not reach the dishes or the like due to an abnormality of the cleaning pump 23 or the like during the cleaning process. Even if it comes in contact with water, it is cleaning water with a high degree of pollution that is close to boiling water, so it means that the operation will continue with poor cleaning.

未然に防ぐことができる。In the second means, the temperature detecting element is provided in the vicinity of the heater so that the temperature detecting element detects the temperature of the cleaning water in the cleaning step and the temperature of the heater in the other steps. Therefore, if the cleaning water is not supplied to the heater due to an abnormality of the cleaning pump during the cleaning process, the heater will overheat and the cleaning water will not be heated, resulting in poor cleaning. The temperature of the heater will be detected instead of the temperature of water. Therefore,
Since the temperature of the temperature detection element becomes higher than the predetermined temperature for cleaning the cleaning water during the cleaning process in a short time, the controller judges that the cleaning pump etc. is abnormal in a short time after the cleaning process is started and the user Can be notified. At the same time, the energization of the heater can be stopped. As a result, it is possible to prevent an excessive temperature rise portion or a cleaning failure from occurring during the cleaning process.

When the operation is started, the water supply valve 2 is first energized to supply a predetermined amount of cleaning water 3 into the cleaning tank 1. When the washing water 3 reaches a predetermined amount, the washing pump 4 starts operating, pressurizes the washing water 3 containing the detergent, and supplies the washing water 3 to the washing nozzle 5. In this way, the cleaning water 3 is sprayed from the cleaning nozzle 5 and the main cleaning step is performed. The heater 13 is energized during this main washing step. Therefore, the cleaning water 3 circulating in the circulation water passage 14 is supplied to the heater 13 through the injection port 6, and thus heat-exchanges with the heater 13 to be heated. When the temperature of the cleaning water 3 reaches the predetermined temperature for cleaning and the cleaning for a predetermined time ends, the main cleaning step ends. After completion of the main washing step, the rinsing step and the drying step are performed.

ことができる。According to the first embodiment of the present invention thus constructed, the heater 13 is installed on the back surface of the cleaning tank 1 and is not exposed in the cleaning tank 1 by the partition plate 15. It is possible to prevent the tableware from being burned due to falling off from the tableware basket 10 and the user's burns after the operation is completed. Further, in the cleaning step, the cleaning water 3 is supplied to the heater 13 through the circulating water passage 14 to heat it, and in the drying step, the outside air is heated to become warm air through the ventilation duct 12 and the heater 13, and the warm air is cleaned. Since it is supplied into the tank 1 and the dishes and the like are dried, the heater 13 can be used in the washing and drying steps.

Detect the temperature. Therefore, when the cleaning water 3 is not supplied to the heater 13 due to an abnormality in the cleaning pump 4 or the like during the cleaning process, the heater 13 and the cleaning water 3 do not exchange heat with each other, so that the heater 13 is overheated and the cleaning water 3 is discharged. Although it is not heated and a cleaning failure occurs, the temperature detecting element 15 at this time detects the temperature of the heater 13 instead of the temperature of the cleaning water 3 as shown in FIG. Therefore, the temperature of the temperature detection element 15 becomes higher than the predetermined cleaning temperature of the cleaning water 3 during the cleaning process in a short time, and the control device 27 has an abnormality in the cleaning pump 4 or the like within a short time after the start of the cleaning process. Then, the user can be notified. At the same time, the power supply to the heater 13 can be stopped. As a result, it is possible to prevent an excessive temperature rise portion or a cleaning failure from occurring during the cleaning process.
