る。When the operation is started, first the water supply valve 26
Operates to supply a predetermined amount of cleaning water 27 to the cleaning tank 25. Then, the washing pump 28 pressurizes the washing water 27 and sprays it with the detergent from the washing nozzle 29, and the washing process is started. In this cleaning process, the heating element 32 provided in the cleaning tank 25
Is energized to heat the cleaning water 27 to a predetermined cleaning temperature.

Is discharged to the outside of the machine by the drainage pump 33. Then,
A step of rinsing the dishes 30 and the like that are contaminated with detergent or leftovers (food left as stains on the dishes is called leftovers) by newly supplying the washing water 27 and spraying again from the washing nozzle 29. To execute. When this rinsing step is performed for a predetermined time, the wash water 27 is discharged to the outside of the machine again. This rinse step is repeated 3 times in succession. At this time, the leftover dishes are the washing tank 2
5 is collected in the filter 34 provided in FIG.

場合、食器が焼損したり発煙したりする場合もある。ま
た、乾燥工程を終了した直後に使用者が発熱体に接触し
たりすると火傷をする場合も生ずる。However, in the conventional dishwasher / dryer, since the heating element is exposed in the washing tub, when resin dishes or the like fall out of the dish basket, the heating element contacts the heating element. It is thermally deformed and burnt. In this case, the tableware may be burned or smoked. Further, if the user touches the heating element immediately after finishing the drying process, the user may get burned.
【０００８】この様な課題を洗浄工程時間を長くするこ

関しては不十分なものである。このため所定の乾燥性能
を得るためには、乾燥専用の加熱ユニットを設ける必要
がある。In order to solve such problems without prolonging the cleaning process time, a heath heater is used as a heating element, and this sheathed heater is brazed to a running water pipe, and this running water pipe is used as a part of the wash water circulating water passage. Some of the configurations used. However, in this heating unit, the heating performance of the washing water in the washing process is satisfactory, but the drying performance of the dish is not sufficient because hot air of the required temperature cannot be obtained in the drying process. Therefore, in order to obtain a predetermined drying performance, it is necessary to provide a heating unit dedicated to drying.

Operation will continue with poor cleaning. Also, in the washing process, the washing water is heated to a high temperature to wash the dishes,
At the end of the washing process, the dishes are heated to a high temperature. In the rinsing process, the newly supplied wash water is low in temperature at first, so that the low-temperature wash water is supplied to the tableware in the high temperature state, so that the tableware is rapidly cooled and the tableware such as glasses may be broken. There is. Also, since low-temperature washing water is supplied in the washing step and rinsing step, it takes time to heat the washing water to the predetermined temperature for washing, and as a result, it takes a lot of time for the operation of the dishwasher to finish. Takes.

The washing water is supplied to the heating unit and the washing nozzle to wash dishes and the like. At this time, since the wash water is heated to the predetermined temperature for washing, the dishes washed with the wash water are also heated and are in a high temperature state at the end of the washing process. Therefore, in the rinsing step, the on-off valve is first closed and the newly supplied cleaning water is supplied only to the heating unit for heating. Then, when the washing water is heated to some extent, the on-off valve is opened to supply the washing water to the heating unit and the washing nozzle as well to rinse dishes and the like.
【００２６】従って、洗浄工程終了時に高温状態である

The on-off valve is opened to supply washing water to the heating unit and washing nozzle to wash dishes and the like. At this time, since the wash water is heated to the predetermined temperature for washing, the dishes washed with the wash water are also heated and are in a high temperature state at the end of the washing process. Therefore, in the rinsing step, the on-off valve is first closed and the newly supplied cleaning water is supplied only to the heating unit for heating. Then, when the washing water is heated to some extent, the on-off valve is opened to supply the washing water to the heating unit and the washing nozzle as well to rinse dishes and the like. Therefore, since the dishes or the like that are in a high temperature state at the end of the washing process are not rapidly cooled by the washing water, it is possible to provide the dishwasher / dryer that can prevent the dishes such as glasses from breaking.

きる。The present invention also provides a cleaning tank, a water supply path for supplying cleaning water to the cleaning tank, a tableware basket for storing dishes and the like,
A cleaning pump for circulating the cleaning water in the cleaning tank, a cleaning nozzle having a spray hole for spraying the cleaning water on dishes and the like, and a heating unit having a heating element incorporated therein for heating cleaning etc.,
Ventilate the inside of the cleaning tank, a first circulating water channel that supplies cleaning water to the heating unit, a second circulating water channel that connects the cleaning tank and the heating unit, a third circulating water channel that supplies cleaning water to the cleaning nozzle. By providing a ventilation fan and providing a heating unit in a part of the water supply path, the cleaning water supplied in the cleaning and rinsing process passes through the heating unit before being supplied into the cleaning tank, and is therefore heated by the heating unit. . for that reason,
Since the cleaning water heated to some extent is supplied to the cleaning tank, the cleaning water can be heated to a predetermined temperature for cleaning and rinsing in a shorter time. Therefore, since the time for heating the wash water in the washing process and the rinsing process is shortened, the washing time and the drying time are shortened. Therefore, it is possible to provide the dishwasher / dryer that can reduce the operation time.
