Description
Technical field
The utility model relates to the draining pump vibration isolation structure of draining pump vibration and noise reducing structure, especially roller washing machine.
Background technology
At present, the screws forms that are rigidly connected that adopt between roller washing machine draining pump and main box in the process of laundry machine dehydration, especially during the residual water of row more, because this body structure of draining pump inherent characteristics and abominable impact load condition cause the single-frequency vibration of pump own very big.The vibration of pump itself is directly passed to casing by being rigidly connected, after casing amplifies, on the relevant frequency content of the speed of pump, cause serious single-frequency noise, make the complete machine sound quality very inferior, become a very main factor of customer complaint on the market.
The utility model content
The purpose of this utility model is in order to overcome washing machine in dehydration, because draining pump impact vibration transfer is to casing, and the shortcoming that causes complete machine noise quality to descend.The utility model provides a kind of draining pump vibration isolation structure that can be used for roller washing machine, adopt a kind of brand-new non-linear vibration insulation structure, can reduce roller washing machine under the dehydration working condition draining pump vibration to the transmission of casing, reduce the draining pump drainage noise, thereby improve complete machine oscillation noise quality.
For reaching above purpose, solution of the present utility model is:
A kind of draining pump vibration isolation structure that can be used for roller washing machine, the installation contact-making surface of vibration insulation structure has been distributed with the small lugs of vibration isolation effect, and the one-body molded connecting plate that is connected and fixed that is useful on around vibration insulation structure, connecting plate is provided with the groove that is connected in casing.
Further, this vibration insulation structure is a circular ring structure, and the aperture surface of annulus is the broached-tooth design with damping effect.
This vibration insulation structure is a rubber component.
This connecting plate is three, and corresponding central angle is respectively 90 degree, 180 degree, 90 degree between the adjacent connecting plate.
This correspondence central angle is that two adjacent connecting plates of 180 degree are that connecting plate is installed, and which is provided with installing hole.
This correspondence central angle is that another connecting plate outside the 180 two adjacent connecting plates of spending is the guiding connecting plate, which is provided with pilot hole.
This groove is that 1mm is thick.
This vibration insulation structure is used for roller washing machine, and it is located between washing machine main box and the draining pump, locatees via guide frame by vibration insulation structure being sheathed on draining pump cavity end, and fixes by stop screw.
Owing to adopted above technical scheme, the utlity model has following beneficial effect: the utility model can guarantee to have the effect of damping when work, reduce the noise when using; Have enough intensity when falling, guarantee that total can not lose efficacy.
Description of drawings
Fig. 1 is the structural representation of spacer assembly of the present utility model.
Fig. 2 is installed on structural representation on the washing machine for the utility model.
Fig. 3 is a partial structurtes schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing illustrated embodiment the utility model is further described.
The utility model roller washing machine draining pump vibration isolation structure, its structure mainly by draining pump axially, vibration-proof structure radially; Draining pump is axial, the radial location structure; Casing is installed by gathering sill and trip bolt constitutes.By axially and the radially-directed structure position installation, by axially and vibration-proof structure radially carry out vibration isolation, undertaken spacingly by trip bolt, damping effect is arranged when guaranteeing work, enough intensity is arranged when falling, guarantee that structure did not lose efficacy.
Among Fig. 1-Fig. 2: between main box 1 and pump body structure 2, increase vibration insulation structure 3, this vibration insulation structure 3 is a rubber component, and be circular ring structure, its edge is one-body molded three connecting plates 31, corresponding central angle is 90 degree, 180 degree, 90 degree between the adjacent connecting plate 31, wherein corresponding central angle is that two adjacent connecting plates 31 of 180 degree are installing hole 311, and another connecting plate is a pilot hole 312, installing hole 311 and pilot hole 312 big or small consistent.The installing hole connecting plate 31 that is used to connect can increase, but can reduce vibration isolating effect on certain degree.The internal radius of vibration insulation structure 3 is a zigzag structure 33, and the surface of annulus one side has been provided with the small lugs 32 of vibration isolation effect, and this side is for being adjacent to the casing side during installation.
As shown in Figure 3, be to be with groove 313 in the middle of the connecting plate 31,313 about 1mm are thick for groove, card casings (about 1mm is thick) in the middle of the groove 313 when it is installed, the rubber bumps on connecting plate 31 both sides just can play the effect of vibration isolation like this.During installation, vibration isolation rubber structural member 3 is enclosed within draining pump 2 cavity ends, three connecting plates 31 and draining pump 2 cavity connecting hole position alignment on the vibration insulation structure 3, by the guide pillar structure being installed pump 2 and vibration insulation structure 3 are assemblied on draining pump 2 installing plates, adopt the screw of being with limiting structure to pass installing hole 311 and carry out fastening at the pilot hole 312 of vibration insulation structure 3.
The utility model can reduce roller washing machine draining pump impact vibration under the dehydration working condition transmission of casing is reduced the draining single-frequency noise that causes because of the vibration of draining pump impact, thereby improves complete machine oscillation noise quality.
The utility model has been abandoned traditional rigidity on-link mode (OLM), adopts flexible link, reduces link rigidity effectively; Adopt non-linear rigidity to satisfy the self adaptation of structure rigidity under different operating mode situations, to reach optimum efficiency; The employing limiting structure carries out the rigidity bound to be guaranteed, thereby guarantees the reliability and the validity of total.
The above-mentioned description to embodiment is can understand and use the utility model for ease of those skilled in the art.The person skilled in the art obviously can easily make various modifications to these embodiment, and needn't pass through performing creative labour being applied in the General Principle of this explanation among other embodiment.Therefore, the utility model is not limited to the embodiment here, and those skilled in the art should be within protection domain of the present utility model for improvement and modification that the utility model is made according to announcement of the present utility model.
