2. Description of the Related Art FIG. 14 shows a configuration example of a conventional dishwasher, and FIG. 15 shows an example of an operation flow of the dishwasher.
Tableware is stored in a tableware basket 74 in a washing tank 72 of the dishwasher. A drainage channel communicates with the cleaning tank 72, and a filter 76 is provided at the entrance. The cleaning tank 72 communicates with an introduction path 82 for drying air, and the introduction path 82 is provided with a blower fan 78. When the blower fan 78 rotates, drying air is sucked from the intake port 80, introduced into the washing tank 72 from the introduction path 82, dries the dishes, and is exhausted from the exhaust port 84. A heater 88 is provided in the cleaning tank 72 to heat the drying air to promote the drying of the dishes.
A branch passage 86 branches off from the drying air introduction passage 82, and the branch passage 86 is provided with an ozone generator 90. The air containing ozone flowing through the branch passage 86 and the air passing through the cleaning tank 72 are mixed in the mixing section 92, and after mixing, are exhausted from the exhaust port 84.
When the dishes are stored in the washing tank 72 in step 120 of FIG. 15 and the detergent is put in in step 122, a washing step (step 124) and two rinsing steps with warm water (steps 126 and 128) are executed. Wash dishes. The garbage removed from the dishes is captured by the filter 76. In the drying step of step 130, the blower fan 78 and the heater 88 are operated. As a result, air is introduced from the air inlet 80 into the washing tank 72 to dry the dishes. Since the heater 88 heats the drying air, drying of the dishes is promoted. At this time, since the garbage on the filter 76 is also heated at the same time, an odor component may be generated, and an odor may be generated.
Part of the air sucked from the inlet 80 flows through the branch passage 86 and reaches the mixing section 92 including ozone generated by the ozone generator 90. The air that has flowed through the washing tank 72 and dried the dishes (this air may contain a malodorous component) also flows into the mixing section 92. Since the ozone and the air containing the offensive odor are mixed in the mixing section 92, the offensive odor component is decomposed by the ozone. Therefore, the odor component is not exhausted from the exhaust port 84. Excess ozone is decomposed by an ozone decomposition catalyst provided at the exhaust port 84. In the drying step of step 130, the ozone generator 90 is also operated at the same time as the blowing fan 78 and the heater 88 are operated. When a predetermined drying operation time has elapsed, the power is automatically turned off in step 132, and the operation of the dishwasher is stopped. Patent Document 1 describes an example of a dishwasher incorporating the above-described ozone generator.
