A sprayer and a dishwasher

By using the opening and closing of the water pressure control valve in the sprayer, the multi-directional rotation of the spray arm is achieved, which solves the dead angle problem caused by the unidirectional rotation of the sprayer in the prior art, improves the cleaning effect and reduces the cost.

AI Technical Summary

Technical Problem

Existing dishwasher sprayers can only achieve one-way rotation, which increases the probability of dead angles and requires additional power structures or spray arms, resulting in increased space and cost.

Method used

A sprinkler with a spray chamber and a rotating shaft is used. The rotation direction of the spray arm is changed by the opening and closing state of the valve. The switch of the water pressure control valve is used to realize the clockwise and counterclockwise rotation of the spray arm, thereby increasing the spray range and reducing dead angles.

Benefits of technology

The flexible rotation state switching of the sprayer is realized, dead angles are reduced, cleaning effect is improved, the structure is simple, the cost is low, no additional power structure is required, and the user is easy to operate.

Abstract

The application discloses a sprayer and a dishwasher, and relates to the technical field of household appliances, in particular to a sprayer and a dishwasher. The sprayer comprises a spraying arm, a rotating shaft, a first spray hole, and a valve. The spraying arm has a spraying cavity. The rotating shaft is connected with the spraying arm, and the spraying arm can rotate around the rotating shaft. The first spray hole is arranged on the spraying arm and communicates with the spraying cavity, and is used for spraying water outward. The valve is arranged in the spraying cavity or the first spray hole, and is used for controlling the opening and closing of the first spray hole to change the rotating state of the spraying arm. The valve is used for controlling the opening and closing of the first spray hole to change the rotating state of the spraying arm, so that the spraying arm can rotate clockwise and counterclockwise. On one hand, the rotating state of the spraying arm can be controlled, and on the other hand, the spraying range is increased, the dead angle of spraying is effectively reduced, and the spraying effect is improved.
