Spraying system installed on cleaning machine and cleaning machine

Abstract

The invention provides a spraying system installed on a cleaning machine, which comprises a spraying arm component, a pump body and a pump body power source for driving the pump body to rotate. The spraying arm component is hollow to form a water outlet cavity; the spraying arm component comprises a spraying arm; a plurality of water outlets communicated with the water outlet cavity are arranged on the surface of the spraying arm; the bottom of the spray arm is provided with a mounting hole, the upper section of the pump body extends into the water outlet cavity from the mounting hole, the pump body comprises an impeller and blades arranged outside the impeller, the spraying system further comprises a filter screen cover, a shaft hole penetrates through the center of the impeller, a main shaft of the pump body power source extends into the water outlet cavity through the shaft hole, the spraying arm is rotationally supported on the main shaft, the periphery of the impeller is sleeved with a drainage piece, the drainage piece forms a pump body water suction port at a position corresponding to the bottom of the blade, the filter screen cover covers the pump body water suction port sothat the filter screen cover, the pump body and the spraying arm assembly surround together to form a circulating draining area. The spraying system has the advantages of high coaxiality, simpler structural design and more convenient molding.

Description

technical field [0001] The invention relates to a kitchen utensil, in particular to a washing machine and a spraying system thereof. 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 water pumps...

AI Technical Summary

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 and assembly; and because other components are needed to complete the rotational support of the spray arm, if there is a slight error in the coaxiality of the parts during installation, after long-term use, the spray arm will easily interfere with other components (such as water pumps) in the tank; except In addition to the above-mentioned problems, although this kind of open water pump reduces the setting of connecting pipelines compared with traditional water pumps, in order to avoid clogging the pump body with residues in the water, it is also necessary to install a large-area draining plate in the tank for cleaning. water circulation filter

The large-size drain plate limits the cleaning space of the sink to a certain extent, and it is inconvenient to disassemble and assemble when cleaning and maintenance are required. In addition, in actual implementation, the support and fixation of the drain plate also requires the cooperation of other components

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