Description
Technical Field
The utility model relates to a drain pump, especially a small-size drain pump of silence for domestic washing machine.
Background
Household washing machines have been widely used as household electrical appliances essential to daily life. The drainage capacity of the washing machine is also used as a measurement standard to judge the performance of the washing machine, the drainage of the washing machine is mainly carried out by discharging water in a case through a drainage pump, in the drainage process, higher lift and higher flow are required, and meanwhile, the noise in work is required to be minimum.
the noise of the drainage pump mainly comes from washing of water flow and an impeller in the drainage pump in work, the impact force of the water flow is large due to the fact that a drainage pipeline is thin, and the noise, particularly the water flow sound, is very large. Therefore, a drainage pump with a silencing performance is needed to meet the daily life requirement.
Disclosure of Invention
The utility model provides a small-size drain pump of silence, under the prerequisite of guaranteeing higher lift and flow, the noise is lower, can satisfy service environment's requirement more.
Realize the utility model discloses the technical scheme of purpose as follows:
The small mute drainage pump is characterized in that the impeller comprises a connecting shaft rod, blades are distributed in a star shape on the side wall of the connecting shaft rod and comprise transverse pieces and longitudinal pieces, one end of each transverse piece is connected to the connecting shaft rod, the other end of each transverse piece is connected to the end of each longitudinal piece, two side walls of each longitudinal piece are provided with drainage grooves, the depth of each drainage groove is gradually reduced from top to bottom, water outlet pieces are arranged on the bottom surfaces of the longitudinal pieces in a clinging mode, water outlet holes are formed in the water outlet pieces, and the arrangement of the water outlet holes is also in a star shape.
furthermore, the water outlet hole body is inclined, and the inclined direction of the water outlet hole body inclines to the edge of the water outlet sheet.
Further, the width of the impeller is gradually widened from top to bottom.
Furthermore, the size of the widest position of the width of the impeller is not smaller than the aperture of the water outlet hole.
Furthermore, the water outlet device also comprises a ring wall, wherein the ring wall surrounds the longitudinal edge of the impeller, meanwhile, the inner wall of the ring wall is provided with a longitudinal groove line, and the ring wall is connected with the water outlet sheet.
According to the structure, the beneficial effects of the utility model are that:
1. through the specially designed impeller, the whole draining pump is ensured to have higher lift, and the draining flow is faster;
2. Through the impeller of special design, reduce the intensity of rivers and impeller striking and the noise that the striking was sent, reach the silence requirement in the drainage process.
Drawings
fig. 1 is a cross-sectional view of the present invention;
FIG. 2 is a schematic view of the impeller structure of the present invention;
FIG. 3 is a partial enlarged view of the impeller of the present invention;
fig. 4 is a partially enlarged schematic view of the present invention.
Detailed Description
Referring to fig. 1 to 4, a small-sized silent draining pump includes a draining pump housing 1 and a motor housing 2, an impeller 3 is arranged in the drainage pump shell 1, a drainage motor 4 is arranged in the motor shell 2, the drainage motor 4 drives the impeller 3 to rotate, the impeller 3 comprises a connecting shaft rod 5, blades 6 are distributed on the side wall of the connecting shaft rod 5 in a star shape, the blades 6 comprise transverse blades 6-1 and longitudinal blades 6-2, wherein one end of the transverse sheet 6-1 is connected with the connecting shaft lever 5, the other end is connected with the end head of the longitudinal sheet 6-2, the water outlet device is characterized in that drainage grooves 7 are formed in two side walls of the longitudinal piece 6-2, the depth of each drainage groove 7 is gradually reduced from top to bottom, a water outlet piece 8 is arranged below the impeller and clings to the bottom surface of the longitudinal piece, water outlet holes 9 are formed in the water outlet pieces 8, and the arrangement of the water outlet holes 9 is star-shaped.
According to above-mentioned structure, the impeller is rotated by the drainage motor drive, and in drainage process, water passes through the impeller and discharges, when rivers pass through the impeller, through the stirring of impeller, forms the vortex flow, because be equipped with the drainage groove on the vertical piece, and the degree of depth of drainage groove is from last to descending the decline gradually, proves under the experiment, under this kind of drainage groove, the vortex flow that rivers formed is fast, and rivers are decurrent to crowd the ability can the reinforce.
Meanwhile, in order to reduce the sound of the swirling flow, the water outlet sheet is adopted to control the trend of water flow during water outlet, so that disordered underwater sound is avoided.
The apopore hole body be the slope form, its incline direction all leans on the water sheet edge, rivers outwards spread like this, further avoid the noise of water collision.
In order to better form the water flow eddy current, the specification of the impeller is designed as follows:
1. The width of the impeller is gradually widened from top to bottom, and when water flow impacts the impeller, the impeller with the specification disperses the water body and is more favorable for the water flow to enter the drainage groove;
2. the widest size of the impeller is not smaller than the aperture of the water outlet hole, so that the dispersion effect of the water outlet hole on water flow is more remarkable, and the water outlet area of the water outlet hole is not the whole aperture but part of the aperture when the water outlet hole passes through the water outlet hole.
In order to better ensure the sealing performance of the drainage pump, the drainage pump further comprises a circular wall 10, the circular wall surrounds the longitudinal edge of the impeller, meanwhile, the inner wall of the circular wall 10 is provided with a longitudinal groove line 11, and the circular wall is connected with the water outlet sheet
The above is only the preferred embodiment of the present invention, not to the limitation of the present invention in any form, all the techniques of the present invention are substantially any simple modification and equivalent changes to the above embodiments, all falling within the protection scope of the present invention.
