Technical Field

The utility model relates to the technical field of dish washing machines, in particular to a spray arm for a cleaning machine and the cleaning machine with the spray arm.

Background

Due to the large volume of the box type dish washing machine, in order to ensure the cleaning effect, a lower spray arm which sprays upwards is generally arranged at the bottom of the box body, and an upper spray arm which sprays upwards is arranged at the middle part of the box body.

The existing upper spray arm structure is characterized in that supplied water flow generally comes from circulating water in a box body, namely the circulating water is conveyed from the bottom of the box body to the top of an upper spray arm through a vertically arranged pipeline by a water pumping mechanism and then upwards sprayed by the upper spray arm. Water flow enters the upper spray arm from the top of the upper spray arm, flows into the left channel and the right channel of the upper spray arm and is sprayed out from the spray holes in the top wall of the upper spray arm.

The spray holes on the upper spray arm are generally circular holes, water flow sprayed out of the circular holes is columnar, the water flow is concentrated, the impact force is large, the cleaning machine is suitable for cleaning stains which are difficult to clean, and the coverage area is small. If all the spray holes are circular, a large number of holes are needed to achieve full coverage of the tableware, but the water flow impact force is reduced along with the increase of the number of the spray holes, and the increase of the number of the holes can influence the water flow strength.

The structure can restrict the range of the water column sprayed from the edge of the elongated hole so as to avoid the transition from diffusing outwards and causing waste due to the corresponding tableware-free area.

In the utility model, the side wall of the body is provided with a water spray opening which is communicated with the flow passage and is used for balancing the rotating speed of the spray arm, and the water spray opening is arranged close to the end part of the body. The water column sprayed by the water spray opening can balance the rotating speed of the spray arm through water flow release on one hand, and on the other hand, the sprayed water column can clean the inner wall of the washing cavity so as to keep the inner wall of the washing cavity clean.

The cleaning machine with the spraying arm comprises a box body, wherein the spraying arm can be rotatably arranged in the box body, and runners on two sides of a water inlet of the body are formed into arc runners with opposite bending directions. The spraying device is characterized in that a partition plate assembly capable of dividing the inner cavity of the box body into an upper space and a lower space is arranged in the middle of the box body, at least part of the partition plate assembly is detachably or movably arranged in the box body so as to communicate or partition the upper space and the lower space, and the spraying arm is arranged in the upper space and is close to the separation position of the upper space and the lower space. When more dishes are washed, the upper space and the lower space can be communicated for use, and when less dishes are washed, the upper space and the lower space can be separated, and only the lower space is used for washing, so that the effects of water saving and dual purposes of one chamber are achieved.

Compared with the prior art, the utility model has the advantages that: under the condition that the number of the spray holes is not changed, the circular holes provide spray water columns with concentrated water flow and large impulsive force, and the water columns with larger spray range are provided by utilizing the strip-shaped structure of the slender holes and the funnel-shaped structure of the inner walls of the slender holes, which are gradually increased along the direction of the water flow, so that the sweeping range of the water flow is expanded under the condition of considering the impact force of the water flow, the cleaning dead angle is favorably eliminated, and the cleaning effect is improved.
