First, cleaning mode

1. Double spray conditions

When the pressure P in the casing 5 is smaller than the opening pressure P0 of the drain valve 53 and larger than the opening pressures P1 and P2 of the two pressure valves 8, the drain valve 53 is in a closed state, the two pressure valves 8 are opened, and the water in the casing 5 passes through the two pressure valves 8 and enters the respective spray arms 3 along the water inlet pipe 6, so that the double spray effect is realized.

2. Single spray condition

Under the condition that the tableware is less, the tableware only needs to be placed above a certain spraying arm 3, and the single spraying is utilized for cleaning, so that the cleaning effect can be improved. The specific implementation method comprises the following steps:

Similarly, by adjusting the first pressure valve opening pressure P1 and the second pressure valve opening pressure P2, P1 is greater than P, and P2 is less than P, a single spray effect can be achieved.

Two, forced exhausting mode

After the washing mode is finished, the drain valve 53 is opened, at this time, P0 is equal to 0, the water flow in the casing 5 directly flows out along the drain valve 53, and even if the impeller 7 works at this time, because the pressure relief opening at the drain valve 53, the pressure in the casing 5 is not greater than the opening pressure of the two pressure valves 8, namely, the two pressure valves 8 are not opened under the condition that the drain valve 53 is opened, so that the forced draining function is realized.
