Pulsator washing machine

Abstract

The invention discloses a pulsator washing machine which comprises a water containing barrel, a water drainage pump, a water drainage pipeline and a unidirectional valve, wherein one end of the water drainage pump is connected with the bottom of the water containing barrel; one end of the water drainage pipeline is connected with the water drainage pump; one part of the water drainage pipeline extends to a position not lower than the highest set water level of the water containing barrel; and the unidirectional valve is arranged at the upper part of the water drainage pipeline and is used for enabling air flow to enter the water drainage pipeline in one direction. According to the pulsator washing machine disclosed by the embodiment of the invention, the siphon phenomenon caused by a pressure difference between inside and outside of the water drainage pipeline is effectively avoided, the problem that the washing machine cannot work normally or water is wasted is avoided, the working stability of the washing machine is improved, and the pulsator washing machine has energy-saving and environment-friendly effects.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a pulsator washing machine. Background technique [0002] The pulsator or stirring type automatic washing machine in the related art mainly contains two kinds of upper drainage (forced drainage) and lower drainage (gravity drainage) according to its drainage mode. In order to prevent the water and electricity safety hazards caused by the water inlet valve or water level detection and control components of the washing machine failing, an "overflow pipe" is generally installed on the bucket of the washing machine to ensure the water inlet valve or water level of the washing machine. When the detection and control components fail, the overflowing water can flow away from a relatively safe channel (overflow pipe). For bottom drainage (gravity drainage) washing machines, the outlet of the overflow pipe is connected to the outlet side of the drain valve. Under normal circumstances,...

AI Technical Summary

Problems solved by technology

For top drainage (forced drainage) washing machines, in order to maintain the water level in the bucket during washing, the highest point of the drainage pipe needs to be higher than the set maximum water level of the washing machine, and the position of the outlet of the drain pipe is relatively high. Water cannot flow away from the drain pipe. In areas where upper drainage is used (such as Latin America), the overflow pipe of the upper drainage washing machine only avoids electrical components.
