Rotary spraying arm for washing device and application of rotary spraying arm

Abstract

The invention discloses a rotary spraying arm for a washing device. The upper surface of the rotary spraying arm is provided with water outlet holes. The rotary spraying arm is characterized by comprising an upper cover and a lower cover which can be combined with each other; a channel is formed between the upper cover and the lower cover; the water outlet holes are formed in positions, corresponding to the channel, of the upper cover; an upper accommodating cavity communicated with the channel is formed in the middle of the lower cover; the channel is formed on two sides of the upper accommodating cavity; and the lower surface of the lower cover is provided with a round hole corresponding to the upper accommodating cavity. The invention further discloses the washing device utilizing the rotary spraying arm. With the cavity which is used for accommodating a water outlet portion of a water pump and communicated with the water outlets, the rotary spraying arm can be manufactured separately from the water pump and is convenient to machine and install.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a rotary spray arm used for the cleaning device, and a sink type cleaning device using the rotary spray arm. Background technique [0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt adhering to the dishes and to clean the dishes. The dishes are placed in the dish frame in the dishwashing cabinet. A general dishwasher includes a pump and a nozzle for spraying washing water, a heater for generating hot water, and the like. Today's dishwashers have begun to use steam to clean dishes. Compared with using heated water, using steam can also reduce the washing time and improve the washing effect. [0003] In order to save space, there have been many sink-type cleaning machines, which are slightly refitted on the basis of current household sinks, and the sink is converted into a cleaning machine, such as the applicant's invention patent applications 20121037456...

AI Technical Summary

Problems solved by technology

Although such a structure has a better cleaning effect, due to the many components and complex structure, and the rotating spray arm needs to be firmly connected with the pump body and the motor, the pump body and the motor also need to be tightly connected, and also need to be tightly connected with the water tank, so In order to effectively clean the objects in the washing machine

Therefore, such a rotating spray arm structure is often difficult to disassemble and install, and some even need to be fixed to ensure that the rotating spray arm will not loosen during cleaning to affect the rotating cleaning effect, so such a washing machine still causes inconvenience.
