ある。With respect to the dishwasher including the above components, the relationship and operation of the components will be described below. When the user places the tableware 2 in the basket 10, stores the dish 2 in the cleaning tank 1 and puts the detergent therein and then starts the operation, first, a predetermined amount of tap water is supplied to the bottom of the cleaning tank 1. Then, the motor 5 and the heater 6 are energized, and the washing water is jetted from the washing nozzle 3 toward the dishes 2 by the washing pump 4 while being heated. When the temperature of the cleaning water reaches a predetermined temperature and a predetermined time elapses from the start of cleaning, the cleaning process ends and the cleaning water is once drained. Next, tap water is newly supplied, and the same operation as the above-described washing process is performed for several minutes to drain the water. After repeating this rinsing step several times, the same operation as the washing step called a heat rinsing step is performed, and when the predetermined temperature is reached, the operation is finished and drained. Finally, in the drying process, the blower fan 7 is operated to discharge the steam in the cleaning tank 1 to the outside of the machine, and at the same time, the heater 6 is intermittently energized to heat the tableware 2 and dry the attached water droplets. It is a thing.

り機外に排出する。The operation of the dishwasher having the above structure will be described with reference to FIG. First, when the user places the tableware 2 in the dish basket 10 and stores it in the washing tank 1 and puts the detergent into it and starts the operation, the water level detecting means 13 supplies water to the washing tank 1 until a predetermined water level is detected. Water is supplied. After reaching the predetermined water level, the process moves to the cleaning step. During the cleaning step, the cleaning water ejected from the cleaning pump 4 is ejected from the cleaning nozzle 3 to wash the tableware 2 placed on the tableware basket 10, and The discharge port 16 is introduced into the casing 12 through the branch port 15 and heated by the heater 12.
And is circulated from the outlet 18 of the cleaning tank 1 to the cleaning tank 1. The washing water ejected from the washing pump 4 is divided into two systems, that is, a water flow that directly contacts the dishes 2 to remove dirt and a water flow that circulates while the casing 12 is being heated and is circulated. At this time, since the heater 11 is arranged outside the bottom of the cleaning tank 1 at a position lower than the water level of the cleaning water detected by the water level detection means 13, the cleaning pump 4 is not operated for some reason during the cleaning process. Even if a situation occurs in which water is not supplied into the casing 12 due to locking, there is an advantage in that the heater 11 does not have a risk of being burnt. Next, since the rinsing process and the heating rinsing process following the cleaning process are the same as those in the conventional example, the description thereof will be omitted and the operation in the drying process will be described. In the drying process, the cleaning water in the cleaning tank 1 is discharged to the outside of the machine, and the cleaning pump 4 also stops, so that the cleaning water in the casing 12 flows into the cleaning pump 4 through the supply port 14. In this state, the blower fan 7 allows outside air to flow from the intake port 19 to the casing 12
It is sent into the inside, is heated by the heater 11 and becomes warm air, and is sent from the discharge port 16 through the connecting pipe 17 to the discharge port 18 in the cleaning tank. The warm air dries the tableware 2 arranged in the cleaning tank 1, and the generated steam is discharged from the exhaust port 9 to the outside of the machine.

りし、掃除をするとき邪魔にならない。As described above, according to the present embodiment, the washing water is circulated in the casing 12 during the washing process, and the wind of the blower fan 7 is sent through the casing 12 during the drying process, so that the heater 11 is casing. Even if covered with 12, the cleaning and drying functions can be achieved. In particular, since the heater 11 is covered with the casing 12 and is not exposed in the cleaning tank 1,
Even if the small plastic tableware 2 falls from the tableware basket 10 during the drying process, there is no risk of the tableware 2 dissolving, odor, etc.
Furthermore, there is no risk of burns if the heater 11 is touched immediately after the operation is completed, and the inside of the cleaning tank 1 is neat and does not interfere with cleaning.

魔にならない。As is apparent from the above description of the embodiments, in the present invention, the heater is provided outside the bottom of the cleaning tank and covered with the casing at a position lower than the water level detected by the water level detection means. In other words, since the heater is covered with the casing and is not exposed, even if small plastic tableware drops from the tableware basket during the drying process, there is no risk of the tableware melting, smelling, or the like. Also, after the end of operation,
There is no risk of burns if the heater is touched immediately, and the inside of the cleaning tank is neat and does not interfere with cleaning.
