Description

Technical Field

[0001] The invention belongs to the field of household appliances, and in particular relates to a cleaning machine. Background Art

[0002] A cleaning machine is a device that sprays cold or hot water onto dishes to remove dirt adhering to the dishes and clean the dishes.

[0003] Current cleaning machines, such as the Chinese invention patent application "An integrated sink dishwasher", whose patent application number is CN202110094693.5 (application publication number is CN112773294A), disclose an integrated sink dishwasher, including a sink, a dishwasher, a faucet and a head assembly, the sink is fixedly connected to the dishwasher, the dishwasher includes a dishwasher tank, a wire management mechanism, a drying system, an automatic door opening mechanism, a water system, a door body rotation mechanism and a door body assembly, a bowl basket is provided in the dishwasher tank, the wire management mechanism and the drying system are arranged on one side of the dishwasher tank, the automatic door opening mechanism is arranged on the front side of the dishwasher tank, a drain outlet is provided at the bottom of the dishwasher tank, a hot air inlet and an exhaust outlet are provided on the inner side of the dishwasher tank, the drying system is connected to the hot air inlet, the water system is arranged below the dishwasher tank, the water system is connected to the drain outlet and the exhaust outlet, the water system and the bottom of the sink are connected with a downpipe, a groove is provided on the top surface of the dishwasher tank, and the door body assembly is connected to the groove through the door body rotation mechanism. Current dishwashers usually have one washing chamber, which consumes the same amount of water and electricity regardless of the number of dishes to be washed, and cannot be adjusted according to the number of dishes to be washed.

[0004] In order to solve the above technical problems, for example, the Chinese utility model patent "Dishwasher", whose patent number is ZL201721368759.0 (authorization announcement number is CN208355377U), discloses a dishwasher, including an outer shell, in which a cavity is arranged; a partition, arranged in the outer shell, dividing the cavity into a first cavity and a second cavity; a first dishwashing component, arranged in the first cavity; a second dishwashing component, arranged in the second cavity; a first door body, adapted to the outer shell, for closing or opening the first cavity; a second door body, adapted to the outer shell, for closing or opening the second cavity. The above patent can choose to put one cavity or two cavities according to the actual number of kitchen utensils to be washed. However, each cavity realizes water supply and drainage through its own independent water inlet system and drainage system. Each drainage system requires a drainage pump, and each water inlet system needs to be equipped with a water pump. Each water pump corresponds to a motor (driving part). Then the whole dishwasher requires two drainage pumps and two water pumps, which increases the cost. In addition, when it is necessary to drain the two cavities at the same time, the two drainage pumps work at the same time. When it is necessary to supply water to the two cavities, the two water inlet pumps need to work, which increases the noise during water intake and drainage.

[0005] Therefore, it is necessary to further improve the existing dishwasher. Summary of the invention
