Washer pressure pipe guiding device for preventing foam and accumulated water

Abstract

The invention discloses a washer pressure pipe guiding device for preventing foam and accumulated water, which is arranged on a washer provided with a pressure type water level detector. The guiding device is arranged in a pressure pipe; one end of the pressure pipe is communicated with an air chamber nozzle of an outer drum and is sealed, while the other end is communicated with the pressure type water level detector and is sealed; the guiding device comprises a foam preventing component capable of preventing large-volume foam from carrying air to enter the pressure pipe, and also comprises an accumulated water guiding component capable of guiding waterdrops to slip along the inner wall of the pressure pipe under the action of gravity and enter an air chamber; the foam preventing component and the accumulated water guiding component are respectively a pressure pipe lead and a pressure pipe connector connected with one end of the pressure pipe lead; the pressure pipe lead is arranged in the pressure pipe; the pressure pipe connector is arranged in the air chamber nozzle communicated with one end of the pressure pipe; and the guiding device damages the foam entering the pressure pipe and guides the accumulated water remaining in the pressure pipe so as to realize accurate water level detection. The guiding device has the advantages of simple structure and low cost.

Description

technical field [0001] The invention relates to a device for accurately detecting the water level of a washing machine, in particular to a flow guiding device for a pressure guiding tube used for preventing foam and accumulated water in a pressure guiding tube of a pressure type water level sensor. Background technique [0002] Existing washing machines, including pulsator washing machines, drum washing machines and agitating washing machines, mostly use pressure water level sensors to judge or determine the water level. The accuracy and reliability of pressure water level sensors directly affect the water consumption and safety of washing machines during users' use. , and the pressure guiding tube of the pressure water level sensor is particularly important as the intermediate link of pressure transmission. [0003] Such as figure 1 As shown, the pressure water level sensor 1' on the washing machine is mainly used according to the connection method shown in the figure: one...

AI Technical Summary

Problems solved by technology

In this structure, the water level sensing hose is installed so as to be separated from the water tank, which can only prevent it from being blocked by debris, and also cannot solve the above-mentioned problem of accurate water level detection related to the influence of foam and accumulated water in the pressure transmission pipe.
