The working process of the cleaning machine is as follows:

the fourth motor drives the rotary valve 61 to rotate to a conducting state (closed by C) from B to A, and water is fed when the cleaning machine is normally cleaned, namely water in the water inlet channel 13 enters the diversion channel 5, flows into the connecting section after passing through the diversion sections 51 symmetrically arranged on the diversion channel 5, and finally enters the draining cavity 101. In the cleaning process of the cleaning machine, when a part of water flow in the draining cavity 101 at the bottom of the cleaning machine enters the first spraying part 2, the other part of water flow enters the water flow channel 84 along the water guide channel 8, and rotates at the second impeller 85 to realize acceleration and pressurization, and the water flow is thrown into the two side sub-channels 811 and further flows into the water flow channel 741, because the ejected water flow has certain speed and pressure, the water flow ejected from the water flow channel 741 can quickly flow along the spraying channel 731 of the corresponding layer and is finally guided to be sprayed onto the surface of tableware, so that the cleaning of the transverse dimension in the space is realized, and particularly referring to the direction indicated by the hollow arrow in fig. 4, the deficiency of the effect of the longitudinal cleaning of the first spraying part 2 from bottom to top is made up. So, both realize the vertical upwards spraying washing from bottom to top through first spraying 2, spray the horizontal spraying washing to kitchen utensils and appliances such as bowl and dish by spraying the piece realization through the lateral part.

When the cleaning machine is about to finish cleaning, the independent water inlet channel 13 is opened, when the rotating valve 61 rotates to a conducting state from C to AB, water flow in the water inlet channel 13 enters the water inlet channel 311 of the second spraying part 3, the diversion grid plate 3111 in the water inlet channel 311 reduces the occurrence of the eddy phenomenon of the water flow, the water flow impacts the third impeller 32 to generate circumferential component force to drive the third impeller 32 to rotate and throw the water flow into each diversion channel 315 in the communication channel, the partition plate 314 in the communication channel reduces the occurrence of the eddy phenomenon of the water flow, so that the water flow entering the diversion channel 315 is sprayed onto the upper surface of tableware from the second spray hole 3151, and finally, the top-down full-coverage washing is realized, so that the second spraying part 3 can wash away residues attached to the surface of the tableware back to the first spraying part 2, and the top-down full-coverage washing is given in the final cleaning stage, the overall cleaning effect of the tableware is improved.

After the cleaning machine starts the drying function, the fourth motor drives the rotary valve 61 to rotate to the conducting state from A to B (C is closed), at the moment, the fan 4 in the door body is started, fresh drying air is sucked from the air inlet 120 on the side edge of the door body and blown to the washing cavity, and drying air flow is finally sprayed into the washing cavity 100 from the second spray hole 3151 along the inflow channel 311 and the communication channel 312; while another portion of the drying air flow is pressed at the air outlet 411 of the air duct 41 to flow in the opposite direction through the recessed area 3113, see the direction indicated by the arrow in fig. 5 and 4; the drying air flow enters the diversion channel 5 through the rotary valve 61 and then enters the draining cavity 101, and a part of drying air flow performs targeted drying on a place near the draining cavity 101 where water is easy to accumulate, so that the area is kept dry, and the phenomena that the area is damp and bacteria are bred to cause tableware pollution and the like are avoided; the other part of the drying air flow enters the first spraying part 2 to flow downwards and upwards, and the top of the drying air flow flowing from top to bottom is matched to realize full-coverage convection drying on the surface of the tableware. While the drying air flow is blown into the washing chamber 100, the moisture in the washing chamber 100 is exhausted through the exhaust passage 711 in the mounting shaft 71, so that the air pressure balance in the washing chamber 100 is maintained.

The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter collectively referred to as a first portion and a second portion, respectively), i.e., a fluid (gas, liquid or a mixture of both) can flow along a flow path from the first portion and/or be transported to the second portion, and may be a direct communication between the first portion and the second portion, or an indirect communication between the first portion and the second portion via at least one third element, such as a fluid channel, e.g., a pipe, a channel, a duct, a flow guide, a hole, a groove, or a chamber that allows a fluid to flow through, or a combination thereof.
