Abstract
The invention discloses a water drainage pump. The water drainage pump comprises a straight-through pump casing and a filter plug, and a water inlet end face is arranged between a pump cavity water inlet and a filter chamber. The water drainage pump is characterized in that the filter plug end face and the water inlet end face jointly form a water inlet end face with pressure relief silencing holes. The water drainage pump has the advantages that noise of the water drainage pump can be well eliminated by the pressure relief silencing holes, and further, sizes of the pressure relief silencing holes can be adjusted by adjusting relative positions of the water inlet end face and the filter plug end face, and accordingly convenience and flexibility are achieved.
Description
Technical field
The present invention relates to a kind of draining pump, particularly a kind of washing machine micro-drainage pump.
Background technique
Existing centrifugal drain pump, in use, when the water intake air amount of pump, can cause liquid in discharge tube because air enters rear generation continuous backflow with discharge again phenomenon, air accumulation cannot be discharged in the pump housing, causes producing the continuous backflow of " bang-bang-bang " and discharges noise.In order to reduce this abnormal sound, prior art mainly adopts following several scheme to process.
China Patent No. is 200920230820.4 patent, discloses a kind of low noise pump case of drainage pump of washing machine, and it is provided with an explosionproof hole on the pump housing endophragm end face near between pump chamber and the filter chamber of water outlet.This scheme has been alleviated the problem of noise to a certain extent, but effect is not very desirable.
China Patent No. is 201010154544.5 patent of invention, a kind of drainage pump cover is disclosed, comprise interconnected cylindrical side wall and water intake end face, water intake end face is provided with water intake, water intake is connected with intake pipe, sidewall is provided with drain opening, on water intake end face, has groove, and the degree of depth that is characterized as described groove is deepened to water intake direction gradually from sidewall.This scheme is better to the effect of denoising, still, is easily subject in sewage the impact of impurity larger, to the filter capacity of impurity in water a little less than.
China Patent No. is 201120450997.2 patent of invention, a kind of low noise water discharge pump is disclosed, comprise the pump housing and motor, described motor drives the wheel rotation in the pump chamber that is arranged on the pump housing, the pump case of the described pump housing is provided with water outlet, is characterised in that: the water intake end face of the inner support of the described pump housing is provided with multiple pressure release bloops.This scheme provides a kind of method of noise reduction denoising, but the setting of bloop can not dynamically be adjusted.
Therefore, need to improve existing water pump.
Summary of the invention
Goal of the invention of the present invention is: for the problem of above-mentioned existence, provide a kind of draining pump with pressure release silencing function, abate the noise.
The technical solution used in the present invention is such:
A kind of draining pump, comprises straight-through type pump case and filtering plug, is provided with water intake end face between pump chamber water intake and filter chamber, it is characterized in that: described filtering plug end face and described water intake end face form the water intake end face with pressure release bloop jointly.Pressure release bloop can well be eliminated draining pump noise, and the size of pressure release bloop can regulate by the relative position of adjusting water intake end face and filtering plug end face, convenient, flexible.
Further, the groove that described pressure release bloop is had from inside to outside by water intake end face forms with the groove combination that described filtering plug end face has the ecto-entad mating.The synthetic complete closed pressure release bloop of groove matched group of the semi open model on two end faces.
Described groove distributes along Central Symmetry.Symmetrical
Described groove is " U " shape.The angle of circular arc is conducive to stressed even.
In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows:
1, noise when pressure release bloop can well be eliminated draining pump work.
2, the pressure release bloop being formed by the relative position of two end faces has adjustable characteristic, is convenient to dynamically adapting.
Brief description of the drawings
Fig. 1 is the sectional arrangement drawing of draining pump of the present invention.
Fig. 2 is the structural drawing of filtering plug of the present invention.
Mark in figure: 1 is pump case, 2 is filtering plug, and 3 is water intake end face, and 4 is filtering plug end face.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
In order to make object of the present invention, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1:
As shown in Figure 1, a kind of draining pump, comprise straight-through type pump case 1 and filtering plug 2, between pump chamber water intake and filter chamber, be provided with water intake end face 3, water intake end face 3 has groove from inside to outside, filtering plug end face 4 has the groove of the ecto-entad of coupling, and two end face grooves fit together, composition pressure release bloop.
The beneficial effect of the present embodiment is: pressure release bloop can well be eliminated draining pump noise, and the size of pressure release bloop can regulate by the relative position of adjusting water intake end face and filtering plug end face 4, convenient, flexible.
Further, described pressure release bloop is by combining with described.The synthetic complete closed pressure release bloop of groove matched group of the semi open model on two end faces.
Described groove distributes along Central Symmetry.
Described groove is " U " shape.
The beneficial effect of the present embodiment is: when realizing noise reduction, still ensure good filtering effect, meanwhile, can carry out the adjustment of bloop size by the intake relative position of end face and filtering plug end face 4 of change.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
