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 technology
Existing centrifugal drain pump, when in use, when the water inlet of pump sucks air, can cause liquid in discharge pipe because
Air into it is rear generation continuous backflow accumulate in the pump housing and cannot discharge with phenomenon, air is then exhausted from, cause produce " Hong-Hong-
Hong " continuous backflow with discharge noise.In order to reduce this abnormal sound, prior art China Patent No. is
200920230820.4 patent, discloses a kind of low noise pump case of drainage pump of washing machine, and it is in the pump chamber near outlet
Pump housing endophragm end face between filter chamber is provided with an explosionproof hole.The program alleviates to a certain extent the problem of noise,
But effect is less desirable.
China Patent No. is 201010154544.5 patent of invention, discloses a kind of drainage pump cover, including mutually connected
The cylindrical side wall for connecing and water inlet end face, water inlet end face is provided with water inlet, and water inlet is connected with water inlet pipe, and side wall is provided with
Discharge outlet, on water inlet end face groove is provided with, and the depth for being characterized as the groove is gradually deepened from side wall to water inlet direction.
The program is preferable to the effect of denoising, but, easily affected larger by dirty impurities in water, the filter capacity to impurities in water
It is weaker.
China Patent No. is 201120450997.2 patent of invention, discloses a kind of low noise water discharge pump, including the pump housing
And motor, the Motor drive is arranged on the wheel rotation in the pump chamber of the pump housing, and the pump case of the pump housing is provided with outlet, special
Levy and be：The water inlet end face of the inner support of the pump housing is provided with multiple pressure release bloops.This solution provides a kind of noise reduction
The method of denoising, but the setting of bloop is not adapted dynamically.
Accordingly, it would be desirable to be improved to existing water pump.
The content of the invention
The present invention goal of the invention be：For above-mentioned problem, there is provided a kind of draining with pressure release silencing function
Pump, abates the noise.
The technical solution used in the present invention is such：
A kind of draining pump, including through type pump case and filtering plug, between pump chamber water inlet and filter chamber water inlet is provided with
End face, it is characterised in that：Filtering plug end face collectively forms the water inlet end face with pressure release bloop with the water inlet end face.Let out
Pressure bloop can be very good to eliminate draining pump noise, and, the size of pressure release bloop can be by adjusting water inlet end face
It is adjusted with the relative position of filtering plug end face, it is convenient, flexible.
Further, the pressure release bloop is opened by the groove that water inlet end face is provided with from inside to outside with the filtering plug end face
The groove for having the ecto-entad of matching is combined.The groove combinations of pairs of the semi open model on two end faces is complete into one
Closed pressure release bloop.
Groove on the water inlet end face is distributed along centrosymmetry.Groove on filtering plug end face is along centrosymmetry point
Cloth.
Groove on the water inlet end face is " u "-shaped.Groove on filtering plug end face is " u "-shaped.The angle of circular arc has
Beneficial to uniform force.
In sum, as a result of above-mentioned technical proposal, the invention has the beneficial effects as follows：
1st, pressure release bloop can be very good eliminate draining pump work when noise.
2nd, the pressure release bloop formed by the relative position of two end faces has adjustable characteristic, is easy to dynamically adapting.

Fig. 1 is the sectional arrangement drawing of draining pump of the present invention.
Fig. 2 is the structure chart of filtering plug of the present invention.
Labelling in figure：1 is pump case, and 2 is filtering plug, and 3 is water inlet end face, and 4 is filtering plug end face.
Specific embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order that the objects, technical solutions and advantages of the present invention become more apparent, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, and
It is not used in the restriction present invention.
Embodiment 1：
As shown in figure 1, a kind of draining pump, including through type pump case 1 and filtering plug 2, pump chamber water inlet and filter chamber it
Between be provided with water inlet end face 3, water inlet end face 3 is provided with groove from inside to outside, and filtering plug end face 4 is provided with the ecto-entad of matching
Groove, two facing grooves fit together, and constitute pressure release bloop.
The beneficial effect of the present embodiment is：Pressure release bloop can be very good to eliminate draining pump noise, and, pressure release disappears
The size of sound hole can be adjusted by adjusting the relative position of water inlet end face and filtering plug end face 4, convenient, flexible.
Further, the pressure release bloop is opened by the groove that water inlet end face is provided with from inside to outside with the filtering plug end face
The groove for having the ecto-entad of matching is combined.The groove combinations of pairs of the semi open model on two end faces is complete into one
Closed pressure release bloop.
Groove on the water inlet end face is distributed along centrosymmetry.Groove on filtering plug end face is along centrosymmetry point
Cloth.
Groove on the water inlet end face is " u "-shaped.Groove on filtering plug end face is " u "-shaped.
The beneficial effect of the present embodiment is：While realizing noise reduction, still ensure good filter effect, meanwhile, can
To carry out the adjustment of bloop size by changing the relative position of water inlet end face and filtering plug end face 4.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all essences in the present invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
