Claims

[Scope of claim for utility model registration] A washing chamber 2 for accommodating tableware to be washed, and the washing chamber 2
A cleaning liquid tank 3 is installed directly below the cleaning chamber 2 so that the cleaning liquid and rinsing liquid can be collected, a rinsing liquid tank 4 is installed near the cleaning chamber 2, a spray nozzle 5 is installed in the cleaning chamber 2, and a discharge side is installed. A liquid supply pump 6 connected to the liquid jet nozzle 5, an inflow port 9 and an inflow port 10 connected to the third liquid supply port 3A of the cleaning liquid tank and the liquid supply port 4A of the rinse liquid tank 4, respectively, and an outflow port 11 connected to the suction side of the liquid supply pump 6, and a three-way switching solenoid valve 7 disposed near the liquid supply port 3A of the cleaning liquid tank 3, the dishwasher comprising: The valve 7 has two valve chambers 15A, 15
B is located close to the outflow passage 14 facing the outflow port 11 and communicates with the inflow passage 12, 13 facing the inflow port 9, 10 through each valve seat 16A, 16B, respectively. The valve stems 17A and 17B and the valves 18A and 18B respectively attached to their tips are arranged in the respective valve chambers 15A and 15B, and each valve seat is connected to each other through a wide opening. The valve rods 17A can be alternately connected to and separated from the valve rods 16A and 16B by opening one and closing the other by operating an electromagnetic coil. Bellows 19A and 19B are provided in a cylindrical shape and are surrounded by the bellows 17B and are extendable and retractable in the direction of the respective valve stems, thereby liquid-tightly coupling each bellows 19A and 19B to each of the corresponding valves 18A and 18B. A dishwasher characterized in that the inner space of the bellows 19A, 19B in which the valve stems 17A, 17B exist is formed in a space cut off from the surrounding valve chambers 15A, 15B.
