Description

Dish washing machine

Technical Field

The utility model belongs to the technical field of domestic appliance, specifically speaking relates to a dish washer and spray set of dish washer.

Background

A dishwasher is a kitchen appliance for automatically washing dishes, and is gradually entering more and more general households. The dish washing machine is provided with a cleaning cavity, a spraying device is arranged in the cleaning cavity, tableware is placed in the cleaning cavity, cold water or hot water is sprayed to the surface of the tableware through the spraying device to clean the tableware, and the cleaned tableware is directly stored in the cleaning cavity.

The spraying arm and nozzle structure commonly used in the current dish washer is usually fixed, and the spraying arm rotates to realize circumferential spray washing. Because domestic water pressure is relatively fixed and needs enough water pressure during washing, the open holes on the spray arms cannot be infinite, so that the area between the spray nozzles can not be directly sprayed by water flow, and the water flow intensity must be enhanced by a pressurizing device so that the water flow can be sprayed to other areas to realize dish washing after the water flow collides with dishes.

The spray arm with the fixed structure can not realize that water flow can directly spray and wash tableware in all directions, so that the energy consumption is increased, and the washing time is long. And the spraying range can not cover all corners of the cleaning cavity, and the sprayed water flow further increases the cleaning difficulty, so that the cleaning effect is poor, the cleaning is not thorough, and the cleaning requirements of users can not be met.

Chinese patent with application number CN201610562444.3 discloses a dish washer sprays structure and dish washer, through setting up main spray thrower, includes two spray arms at least at main spray thrower, is equipped with the planet axle at the spray arm tip, and the epaxial rotation of planet is connected with the planet spray thrower, and the planet spray thrower has a spray bar at least, all is equipped with the hole for water spraying on the spray bar. The structure is extremely complex, the production cost is higher, and the problem of washing dead angles caused by the arrangement angle of the cleaned objects still cannot be solved although the spraying range is enlarged.

Chinese patent application No. CN201820004569.9 discloses a multi-fork spray arm structure of a dishwasher, which changes the spray angle of some spray holes by providing a spray arm inclined plane. Because the spray holes are fixedly arranged on the surface of the spray arm, the spray angle is relatively fixed and can not be changed, and cleaning dead angles are inevitably generated.

Chinese patent application No. CN201710635880.3 discloses a dish washer, which comprises at least two spray arms and a spray pipe arranged on each spray arm, wherein the spray device is arranged in a claw shape as a whole. The scheme only changes the outlet height of the spray holes, the angle of the spray holes cannot be changed, and the cleaning dead angle can be generated.

Chinese patent application No. CN201811230801.1 discloses a spraying structure of a dishwasher, which drives a high-pressure nozzle to rotate through a driving device to adjust the spraying angle. Although the jet angle can be adjusted, the energy consumption is inevitably increased by adopting a special driving device, and the structure is complex and the cost is higher.

In view of this, the present invention is provided.
