The heated clean water flows through the first joint 17 and enters the second pump body in two ways. In the first water spray pipe 18 and the second water spray pipe 19, finally spray out from the upper washing wheel 4 and the lower washing wheel 5 into the washing chamber 102 for washing operation;

The clean water sprayed from the upper washing wheel 4 and the lower washing wheel 5 is filtered through the second filter screen 701 and stored in the water collection box 7 after rinsing the dishes, and the first pump body 14 is closed when the water collection box 7 is full of water , stop water supply;

2. Circular washing, the third pump body 21 works to pump the water in the water collection box 7 to the outer cavity 603 of the water distribution box 601, and the water in the outer cavity 603 is filtered again by the first filter screen 602 and then enters the inner cavity In 604, the second pump body 15 works to pump the water in the inner cavity 604 into the heating pipe 16, and the continuous operation of the third pump body 21 and the second pump body 15 can realize the cycle washing operation in the washing chamber 102 .

By setting the cycle washing mode, the utilization efficiency of water resources can be greatly improved, and the waste of water resources can be reduced. By setting the first filter screen 602 and the second filter screen 701, the secondary filtration of clean water can be realized, the filtering effect can be improved, and the pipe can be reduced. risk of traffic jams.

Drainage waterway, after washing is completed, waste water needs to be discharged, the upper drain pipe 23 is communicated with the water distribution box 601, the lower drain pipe 24 is communicated with the water collection box 7, and the upper drain pipe 23 is communicated with the lower drain pipe 24, Specifically, the fourth pump body 22 and the fifth pump body 25 work, the water in the water distribution box 601 is discharged from the upper drain pipe 23 through the fourth pump body 22, and the water in the water collection box 7 is discharged through the fifth pump body 25. The water is discharged from the lower drain pipe 24, and since the lower drain pipe 24 is connected to the upper drain pipe 23 through the third joint 28, finally the waste water can be discharged from the third joint 28;

When the door body 2 is opened, the water dripping into the annular groove 205 enters into the second joint 27 through the downpipe 26 and is finally discharged from the third joint 28 .

By arranging the upper drain pipe 23 and the lower drain pipe 24, not only can the drainage efficiency be improved, but also the water in the pipeline can be drained more cleanly, reducing the accumulation of water in the pipeline. The water is discharged to prevent water accumulation in the annular groove 205.

To clean the washing chamber 102, it is necessary to flush the inside of the washing chamber 102 before the waste water is exhausted and the door body 2 is opened. Specifically, the first pump body 14 is opened, and the external clean water is pumped in from the water inlet pipe 13, and finally the water from the upper washing wheel 4 and the lower washing wheel 5 to clean the washing chamber 102, and the water under washing is directly pumped and discharged through the fifth pump body 25.

Since the water used is the filtered water after washing the bowls and chopsticks during the cycle washing, there will be some impurities in the water. By cleaning the washing chamber 102, the bowls and chopsticks can be rinsed to make the bowls and chopsticks cleaner.

Flush the water circuit, flush the water distribution box 601, the second pump body 15 and the third pump body 21 are closed, the first pump body 14 and the fourth pump body 22 are opened, and the external clean water enters from the water inlet pipe 13 and passes through the first pump body After 14, it enters the outer chamber 603 and flushes the outer wall of the first filter screen 602. The water in the water distribution box 601 is discharged from the upper drain pipe 23 through the fourth pump body 22, thereby realizing the flushing operation of the water distribution box 601. It is beneficial to improve the service life of the first filter screen 602 .

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection of the present invention. within range.
