Description

Technical Field

[0001] The invention relates to the technical field of kitchen appliances, and in particular to an integrated device of a sink and a dishwasher. Background Art

[0002] For desktop and cabinet dishwashers, since the washing space is large, in order to achieve a better washing effect, they are generally designed with three spray arms: top, middle and lower. When working, the washing pump transports water to the top, middle and lower spray arms through pipes. The water is sprayed out from the top, middle and lower spray arms and rinses the dishes before falling back into the water cup at the bottom of the dishwasher. The washing pump transports the fallen water to the top, middle and lower spray arms again to complete a cycle.

[0003] For example, the Chinese invention patent application "Energy-saving dishwasher" (application number: CN201611232345.5) with application publication number CN106859563A discloses a structure, which includes a cavity for accommodating tableware and providing a cleaning space, a spray system for spraying water to clean the tableware, and a pump body for pumping water and supplying water to the spray system; the spray system is arranged in the cavity; the water pumping end of the pump body is connected to the cavity, and the water supply end is connected to the spray system; the spray system includes an inner water pipe and two or more spray devices, and the two or more spray devices are respectively arranged on the inner water pipe; the water supply end of the pump body is connected to a water distribution device, and the water distribution device is provided with two or more water outlets corresponding to the two or more spray devices, and the spray device is connected to the corresponding water outlets; when working, the water distribution device conducts one or more water outlets according to instructions, so that one or more spray devices perform cleaning work.

[0004] In the above-mentioned existing dishwashers capable of bottom spraying and top spraying, the washing chamber is large and can be used to wash more dishes. However, when the number of diners and dishes suddenly increases due to family gatherings, independent dishwashers cannot meet the washing needs. If additional dishwashers are installed, on the one hand, the investment is large, and on the other hand, a large installation space is required.

[0005] In addition, conventional dishwashers generally use a water pump to lift water and spray it onto the dishes in the washing space to achieve the cleaning effect. The highest temperature of the dishwasher during the washing stage usually does not exceed 70°, and stubborn stains may adhere to the surface of the dishes and be difficult to remove. Summary of the invention

[0062] Specifically, Figure 3 , 6 As shown, a partition plate 43 for separating the second accommodating chamber 41 and the third accommodating chamber 42 into relatively independent chambers is provided in the middle of the lower shell 4. The second accommodating chamber 41 and the third accommodating chamber 42 are relatively independent, so that water can be supplied to the lower spray through the upper impeller 1 and water can be supplied to the top and / or middle spray through the lower impeller 2, so as to reduce fluid disturbance between each other and reduce capacity loss, so as to improve water head, water flow and injection force.

[0063] The third accommodating chamber 42 is located below the partition 43 and is roughly disc-shaped. The second water inlet 421 is opened at the center of the bottom wall of the lower shell 4.
