Unidirectional spill-proof structure and washing machine

Abstract

The invention relates to the technical field of washing machines, and discloses a unidirectional spill-proof structure and a washing machine. The unidirectional spill-proof structure comprises a mounting part, a guiding part and a spill-proof part which are sequentially connected; the mounting part is in a tubular shape and is used for being mounted at the end, connected with a washing agent tank,of a hose; the guiding part and the spill-proof part extend into the hose, the two sides of the guiding part are gradually shrunk inwards, and the two sides of the spill-proof part are mutually attached; and the spill-proof part is made of an elastic material. According to the unidirectional spill-proof structure, the unidirectional spill-proof structure is mounted on the hose, connected with anouter cylinder, of the washing agent tank, thus water vapor, condensate water and foam in the hose can be effectively prevented from entering a charging opening of the washing agent tank, and the water dripping phenomenon of the washing machine is reduced. When water enters the washing agent tank, the two sides of the spill-proof part directly bear the effect of the water pressure and are separated, thus water flow flows downwards, water inlet action is completed, when the spill-proof part is impacted by the pressure of a reverse air flow or water flow, the two sides of the spill-proof part are not separated, and the good sealing effect is ensured.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a one-way anti-overflow structure and a washing machine. Background technique [0002] like figure 1 As shown, most of the hoses connecting the detergent box and the outer cylinder of the existing washing machine are U-shaped tubes, which can play the role of connecting the detergent box and the inner and outer cylinder assembly. The reason for using the U-shaped tube is that the inner cylinder needs a sealed environment, and the bottom of the U-shaped tube can store water to form a water seal on the inner cylinder. However, in actual use, the water stored in the U-shaped tube will be affected by the external temperature. For example, in summer, the weather is hot and the temperature is high. The water will evaporate into the detergent box, and then evaporate to the handle or the top box cover. And form condensed water droplets on the handle or box cover. When the user...
