Anti-blocking sprayer and anti-blocking cleaning device

Abstract

The invention discloses an anti-blocking sprayer and an anti-blocking cleaning device. The anti-blocking sprayer comprises a spraying arm, a water passing pipe, a switching cylinder and an elastic piece. When the water pressure of the water passing pipe exceeds a first water pressure, the switching cylinder overcomes the elastic force of the elastic piece to rise to supply water to the spraying arm; when the water pressure of the water passing pipe is lower than the first water pressure, the switching cylinder descends under the action of an elastic force of the elastic piece and sprays waterobliquely downwards from a first spraying hole in the water passing pipe. The anti-blocking cleaning device comprises a cleaning tank, a water collecting cup, a filter cartridge and the sprayer, the water passing pipe is rotatably connected to a water supply pipe, a second limiting structure is arranged between the water passing pipe and the water supply pipe, and the water passing pipe further penetrates through a through hole of the filter cartridge and extends into the cleaning tank to be fixedly connected to the spraying arm; the first spray hole is located above the through hole and facesthe cartridge wall of the filter cartridge. By adopting the technical scheme, once the wall of the filter cartridge is blocked and the pumped water pressure is reduced, water spraying to the wall ofthe filter cartridge is automatically switched to the first spraying hole so as to clean residue, so that the filter cartridge is prevented from being blocked.

Description

technical field [0001] The present application relates to the field of household cleaning devices, in particular to kitchen cleaning devices, such as dishwashers. Background technique [0002] In the prior art, there is a dishwasher that supplies water to the spray arm through a circulation pump. The spray arm is provided with a tangential nozzle, and when the nozzle sprays water to the dishes in the washing tank, the spray arm rotates under the drive of the reaction force. The spray arm is generally installed on the water collecting cup at the bottom of the cleaning tank. The main function of the water collecting cup is to collect the water and residue in the cleaning tank, and after being filtered by the filter cartridge, supply water to the circulation pump and then circulate to the spray arm. The filter cartridge is generally provided with filter holes on the cylinder wall and bottom wall. The filter cartridge in the prior art is generally fixedly connected in the wat...
