Gushing arm assembly and spraying system comprising same

Abstract

The invention provides a gushing arm assembly of a cleaning machine. The gushing arm assembly comprises a gushing arm, a connecting sleeve part and a support rack body, wherein a water outlet is formed in the gushing arm; a flow channel communicated with the water outlet is formed in the gushing arm; an accommodating cavity communicated with the water outlet and the flow channel is formed in the gushing arm; a through hole is formed in the position, corresponding to the accommodating cavity, of the lower surface of the gushing arm and communicated with the accommodating cavity; a connecting arm surrounding the water outlet is formed below the gushing arm; either the connecting arm or the connecting sleeve part is one flexible connection part capable of stretching or retracting in the radial direction; the connecting arm and the connecting sleeve part are in buckled connection after being nested; the support rack body comprises a main rack body and a connecting guide ring connected to the upper part of the main rack body, the connecting guide ring is rotationally connected with the connecting arm, and after the connecting guide ring and the connecting sleeve part are buckled vertically, the connecting sleeve part can be rotationally connected with the support rack body in a vertical limiting manner. According to the gushing arm assembly, the gushing arm can be rotationally mounted on the support rack body through the connecting sleeve part in a direct buckling and vertical limiting manner, and compared with an existing rotary buckle type connecting mode, the structure is more stable.

Description

technical field [0001] The invention relates to a kitchen utensil, in particular to a spray arm assembly and a spray system of a 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). In some existing dishwashers that use an open water pump for water delivery, it is common to set a rotating spray arm at the bottom of the tank as a water outlet component for cleaning to clean the objects. The spray arm is mainly supported on a flow guide bracket. The reaction force of the water...

AI Technical Summary

Problems solved by technology

The angle of each inclined roof needs to correspond to the angle of the outlet. If there is an error in the angle of an inclined roof, it will affect the demoulding efficiency. Manual inspection and manual processing are required, which makes the overall design and demoulding of the spray arm more difficult, the design cost of the mold increases, and the process is cumbersome

When the spray arm is in use, it is supported on the guide bracket by the propulsion of the water flow to rotate the spray arm. In order to realize the rotational connection of the spray arm relative to the guide bracket and limit the up and down movement of the spray arm, the existing structure The washing machine needs to install a turnbuckle assembly between the spray arm and the flow guide bracket. The turnbuckle assembly can rotate relative to the spray arm and the flow guide bracket. However, the connection between the turnbuckle assembly and the flow guide bracket is not stable enough. During the turning process, the turnbuckle assembly is easy to unlock with the deflector bracket

Therefore, the design of the spray arm of existing cleaning machine and the integral structure of cleaning machine also needs to be improved.
