PURPOSE:To reduce washing noise and improve washing performance by forming a washing tank with a double tank made of synthetic resin, forming a water feed passage between an inner tank and an outer tank, and retaining city water there. CONSTITUTION:A washing tank 14 has a double-wall structure integrally formed with an inner tank 14a and an outer tank 14b made of resin. The space inside double walls has an opening section at the upper face, part of the outer tank 14b concurrently serves as part of the outer hull of a product, and a cover 14c covers the main body of the washing tank 14 from the above. The city water fed from a water feed solenoid valve 17 connected to a water feed port 16 provided on the outer tank 14b is fed to the inside of the double walls of the washing tank 14 then fed into the washing tank 14 through multiple discharge ports 15 provided above the inner tank 14a. The city water filled in the double walls can exert its effect as a vibration-proof material and a sound- proof material, no noise is leaked to the outside, and noise can be reduced. Water is fed through the discharge ports 15 provided on the inner tank 14a of the washing tank 14, the food trash stuck on dishes 25 is washed away, thus rinsing performance and washing performance are improved. |
