Spraying system and washing machine provided with same

Abstract

The invention provides a spraying system. The spraying system comprises a spraying arm unit, a pump, and a pump power source for driving the pump to rotate, wherein the spraying arm unit comprises a spraying arm and a spraying arm support assembly supporting the spraying arm to rotate, the spraying arm is provided with water outlets, a mounting hole is formed in the bottom of the spraying arm, theupper section of the pump extends into a water outlet cavity, the pump comprises an impeller and blades, the spraying arm support assembly comprises a hollow sleeve arm downwards extending to the position close to the bottom of the impeller from the periphery of the mounting hole and having the draining effect, the sleeve arm surrounds the outside of the impeller, the spraying arm further comprises a water filtering screen mounted on the spraying arm support assembly, the sleeve arm forms a pump water drawing hole at the position corresponding to the bottom end of the impeller, the sleeve armforms the pump water drawing hole at the position corresponding to the bottom end of the impeller, and the water filtering screen covers the pump water drawing hole so that the water filtering screen, the sleeve arm and the spraying arm define a circular water draining area. For the spraying system, the number of the parts of the washing machine is reduced from the whole, the mounting and dismounting are convenient, and the manufacturing cost of the whole machine is reduced.

Description

technical field [0001] The invention relates to a kitchen utensil, in particular to a washing machine and a spray system of the washing machine. Background technique [0002] A washing machine is a device that sprays cold or hot water onto the dishes waiting to be cleaned to remove the dirt adhering to them for cleaning. A general washing machine includes a pump for spraying washing water, a rotating spray arm, a heater for generating hot water, and the like. In order to save space, many sink-type cleaning machines have occurred in the prior art, that is, on the basis of household sinks, the sink is refitted a little, and the sink is refitted into a cleaning machine (dishwasher). It is common for existing sink-type dishwashers to set a rotating spray arm at the bottom of the sink as a water outlet part for cleaning to clean the objects, and the water flow sprayed by the rotating spray arm to clean the dishes waiting to be cleaned. In some existing dishwashers that use open...

Problems solved by technology

In some existing dishwashers that use open water pumps for water delivery, the design of the connection structure of each component is relatively complicated, and multiple connection parts must be installed only between the pump body and the spray arm, which is not convenient for product opening In addition, although this kind of open water pump has reduced the setting of connecting pipelines compared with traditional water pumps, in order to avoid the clogging of the pump body by residues in the water, it is also necessary to set a large-area draining plate in the tank for Circulation and filtration of cleaning water

The large-sized drain plate limits the cleaning space of the sink to a certain extent, and in actual implementation, the support and fixation of the drain plate also requires the cooperation of other components, which is inconvenient for cleaning and maintenance of the drain plate

Based on the above, the overall structure of the existing cleaning machine is relatively complicated and needs to be improved.
