Abstract
The utility model discloses a check valve for a washing machine. The check valve for the washing machine comprises a valve body arranged at the lower part of a washing agent box and a check sealing piece connected in the valve body in a rotating manner, wherein the check sealing piece is provided with at least one air exhaust structure. When the washing machine carries out rinsing water feeding operation, the water in the washing agent box pushes the lower part of the check sealing piece open and flows into a water inlet pipe, the air in a water containing bucket overflows into the washing agent box from the air exhaust structures on the check sealing piece along the water inlet pipe, and the water feeding and air exhausting are carried out at the same time, so that the smooth water feeding is guaranteed, and the washing agent box can be prevented from leaking water.
Description
Technical field
The utility model relates to the washing machine accessory, particularly a kind of use in washing machine check (non-return) valve.
Background technology
In the prior art, the original state that is installed in the check (non-return) valve of detergent box bottom is a sealing state, and when rinsing inflow, the seal that current are pushed open in the check (non-return) valve is realized water inlet, and after water inlet was accomplished, check (non-return) valve recovered sealing state.Because no any exhaust structure on the seal can not be realized exhaust in water inlet.If the user puts into excessive washing agent, can produce significant foam and stop up overflow pipe, during rinsing inflow, the steel ladle gas inside can't be discharged from overflow pipe; So in the water inlet pipe water inlet, the steel ladle gas inside also can be overflowed from water inlet pipe, thereby check (non-return) valve cuts out, water inlet pipe is closed; Water in the detergent box can't get into steel ladle, overflows from the detergent box mouth on the contrary, influences the normal use of washing machine; Serious meeting damages machine, causes the accident, and has very big potential safety hazard.
The utility model content
The utility model problem to be solved just provides a kind of use in washing machine check (non-return) valve; Simple and reasonable, make water inlet pipe in water inlet, can carry out exhaust, avoid the water in the detergent box to overflow from the detergent box mouth; Improve the safety in utilization of washing machine, reliability is high.
In order to solve the problems of the technologies described above; The utility model adopts following technical scheme: a kind of use in washing machine check (non-return) valve; Comprise the valve body and the non-return seal of switching in valve body that are installed in the detergent box bottom, it is characterized in that: on the non-return seal, be provided with at least one exhaust structure.
Further, said exhaust structure is the breach that is located at non-return seal top.Simple in structure, easy to make.
Further, said exhaust structure is the through hole that is located at non-return seal top.
Further, said non-return seal top is provided with connecting portion and is connected in the valve body, and said exhaust structure is provided with two and be symmetrically distributed in the connecting portion both sides.
After adopting technique scheme; The utlity model has following advantage: when washing machine carries out the rinsing inflow operation; Water in the detergent box is pushed non-return seal bottom open and is flowed into water inlet pipe, and the steel ladle gas inside is along overflowing in detergent box breach or the through hole of water inlet pipe from the non-return seal, and water inlet is carried out with exhaust simultaneously; Guarantee to realize smoothly water inlet, can prevent that again detergent box from leaking.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the entity structure sketch map of a kind of embodiment of the utility model;
Fig. 2 is a cutaway view embodiment illustrated in fig. 1;
Fig. 3 is the structural representation of seal;
Fig. 4 is the sketch map after the utility model assembling.
The specific embodiment
The structural representation of a kind of embodiment of the utility model shown in Fig. 1 to 4, a kind of use in washing machine check (non-return) valve comprises the valve body 1 and the non-return seal 2 of switching in valve body that are installed in detergent box 3 bottoms, on the non-return seal, is provided with at least one exhaust structure.In the present embodiment, exhaust structure is the breach 21 that is located at non-return seal top.And be provided with connecting portion 22 on non-return seal top and be connected in the valve body, breach is provided with two and be symmetrically distributed in the connecting portion both sides.
In the foregoing description, said exhaust structure also can be for being located at the through hole on non-return seal top, and when two through holes were set, through hole also was symmetrically distributed in the connecting portion both sides.
When the utility model carries out the rinsing inflow operation at washing machine; Water in the detergent box is pushed non-return seal bottom open and is flowed into water inlet pipe; The steel ladle gas inside is along overflowing in detergent box breach or the through hole of water inlet pipe from the non-return seal; Water inlet is carried out with exhaust simultaneously, guarantees to realize smoothly water inlet, can prevent that again detergent box from leaking.
