Description

ROTATING SPRAY WALL USED IN WASHING APPARATUS AND APPLICATION THEREOF FIELD OF THE INVENTION [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning apparatus, and more particularly, to a rotary spray arm for a cleaning apparatus.

The dishwasher is a device that cleans dishes by removing cold water or hot water from the dishes to remove dirt from the dishes. The dishwasher is placed in a rack in a washing room, and a typical dishwasher includes a pump and a spray head for spraying wash water, a heater for generating hot water, and the like. Conventional dishwashers have begun to use dishwashers to clean dishes, and compared to using heated water, the use of steam also reduces cleaning time and improves cleaning effectiveness.

 In order to save space, a large number of sink large washing devices appeared. In other words, it was modified a bit based on the sink used in existing homes, and the sink was upgraded to a cleaning device. The applicant's Chinese Patent Application Laid-Open Gazettes CN102940475A and CN102697436A (application numbers 201210374569.5 and 20121015791313.5) are both prior arts that have been modified from existing sinks to cleaning devices, and in particular, the cleaning devices disclosed in CN102940475A refer to rotary spray arms at the bottom of the sink The rotary spray arm is generally connected to a pump, the pump is driven by a motor, and water is supplied to the rotary spray arm by a pump driving action of the motor to perform cleaning.

Such a structure has a relatively good cleaning effect, but has a large number of members and a complicated structure, and the rotary spray arm must be firmly connected to the pump and the motor, and the pump and the motor must be tightly connected and also tightly connected to the sink , So that the cleaning can be effectively performed on the object in the cleaning apparatus. Therefore, such a cleaning apparatus is still inconvenient to use, since such a rotary spray arm structure is usually difficult to detach and some must even be made stationary to ensure that the rotary spray arm does not unravel and affect the spin cleaning effect.

SUMMARY OF THE INVENTION A first object of the present invention is to provide a rotary spray arm for a cleaning apparatus which is easy to be detached from the conventional technical problem.

A second object of the present invention is to provide a rotary spray arm for a cleaning device capable of controlling the rotation speed.

In order to solve the first technical problem of the present invention, a rotary spray arm for a cleaning apparatus includes an upper cover and a lower cover which are formed with an outflow hole on an upper surface thereof, and a flow path is formed between the upper cover and the lower cover Wherein the outlet hole is located at a position corresponding to the flow path on the upper cover, and an upper chamber communicating with the flow path is formed in the middle of the lower cover, the flow path being located on both sides of the upper chamber, And a round hole corresponding to the upper chamber is formed on the lower surface.

 The upper chamber and the round hole receive the water outlet portion of the pump, which pumps water into the rotary spray arm.

In order for the pumped water to be easily injected from the rotary spray arm, a diaphragm is provided between the upper cover and the lower cover, the diaphragm encircling the round hole to form the upper chamber, So that the flow path is formed, and the pumped water can be injected through the outflow hole along the flow path.

 The ratio of the area of the exit hole located at both ends of the upper cover to the area of all the exit holes on the upper cover is 0.05 to 2.

Further comprising a rotation coupling ring connected to a support member located below the rotary spray arm for stabilizing the structure of the rotary spray arm and the pump, wherein the rotation coupling ring comprises a clasping ring And a locking block protruding radially in the circumferential direction of the class ring and engaged with the supporting member.

And the classifying ring is detachably coupled to the lower cover.

The detachable coupling structure of the classing ring and the lower cover can be achieved by various conventional techniques. Preferably, the detachable coupling structure is formed by the rotation coupling ring, Wherein a plurality of resilient engaging portions are provided at intervals in the circumferential direction of the retaining ring and a stepped portion matched with the resiliently engaging portion is provided in the circumferential direction of the classing ring.

In order to solve the second technical problem of the present invention, in order to adjust the rotary spray arm at a proper rotation speed to obtain a comparatively good spraying effect, a balance weight for controlling the rotational speed of the rotary spray arm is symmetrically disposed on both sides of the lower surface of the lower cover By adjusting the weight, the weight of the balance weight is varied to adjust the rotational speed of the rotary spray arm.

Preferably, the balance weight and the lower cover are detachably coupled, and the balance weight and the lower cover are engaged or fixed so that the balance weight can be replaced.

A portion of the guide bracket 52 located on the outer periphery of the lower chamber 522 is provided with a locking block And one end of the holder 523 is opened so that the retaining block 722 approaches the holder 523 by rotating the classing ring 72 so that the holder 523 So that the rotary spray arm 6 and the guide bracket 52 are fixed to each other.

 The balance weight 8 may be symmetrically arranged on both sides of the lower surface of the lower cover 63. The balance weight 8 may be engaged with the lower cover 63 or attached to the lower cover 63, (Not shown). A fixing member 632 is provided on each side of the bottom surface of the lower cover 63 and a space for accommodating the balance weight 8 is provided in the middle of the fixing member 632 And guide ridges matching the guide grooves are provided on both sides of the balance weight 8 so that the balance weight 8 is guided by the guide grooves And can be engaged with the fixing member 63 and fixed. By varying the weight of the balance weight 8, the rotational speed of the rotary spray arm 6 can be adjusted.

Alternatively, the pump may utilize a pump of a generally closed structure, which draws water in the drainage area 32 into the closed pump and into the rotary spray arm 6 from the outlet. In other words, the rotary spray arm 6 is still an outlet member of the closed pump, and the outlet port of the pump can be accommodated in the upper chamber 61 thereof.

The operation of the sink large washing apparatus of the present invention is as follows. First, a dish basket is placed in a sink base body 1, a tableware to be cleaned is placed on a dish basket, the cover plate 2 is closed, and a certain amount of clear water And when clear water flows into the drainage area 32, the motor 4 is operated to rotate the impeller 51. [ The water in the drainage region 32 flows upward from the lower portion of the impeller 51 into the upper chamber 61 and flows into the flow passage 64 from the side of the upper chamber 61 And is sprayed from the outlet hole 621 corresponding to the position of the flow path 64 on the upper cover 62. At the same time, the rotary spray arm 6 rotates by the action of the water flow, Wash.

The water after the washing flows into the drainage area 32 again through the drainage plate 3 and is recycled by the impeller 51 so that the drainage plate 3 not only causes water to flow but also discharges relatively large dirt from the drainage plate 3) to prevent the dirt from entering the drainage area 32 and flowing into the impeller 51 to affect the normal rotation of the impeller 51. Such a structure not only saves water and energy, but also has a good cleaning effect, can be made by retrofitting a domestic sink, and the sink body can be any domestic sink, thus saving cost and saving space in the kitchen. When the function of the cleaning device is not used, simply by removing the rotary spray arm 6, dismantling both the impeller 51 and the guide bracket 52, and then restoring the drain pan 3 to its original position, Can be restored to the sink.
