The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The structural representation of the washing machine that has draining pump that Fig. 1 provides for the utility model embodiment, this washing machine comprises washing machine shell 10 and draining pump 20, also comprises the conventional components in other washing machines, for example cylinder 11 and control device etc.Draining pump 20 comprises housing 21, have water inlet and delivery port on the housing 21, water inlet links to each other with cylinder 11 by first bellows, and delivery port connects second bellows, and second bellows of delivery port can pass the through hole of offering on the washing machine shell 10 and export to the washing machine outside.The motor 22 of common draining pump 20 can be fixed among the housing 21 or be fixed on a side of housing 21.In this washing machine, also comprise beam 30, be illustrated in figure 2 as the structure for amplifying schematic diagram of draining pump and beam.Beam 30 is fixed on the shell 10, and draining pump 20 is fixed on the beam 30, and it is as a whole specifically can be that draining pump 20 is done, and any parts wherein are fixed on the beam 30, and preferably the housing 21 of draining pump 20 is fixed on the beam 30.Have the setting spacing between draining pump 20 and the shell 10, promptly neither directly be fixedly linked between draining pump 20 and the shell 10, also do not fit mutually, but keep certain spacing.
When this washing machine carries out drain operation, 22 work of draining pump 20 motors produce vibration, the housing 21 that the vibration of motor 22 drives draining pump 20 together vibrates, the vibration transfer of draining pump 20 obtains certain buffering to beam 30, and, owing between draining pump 20 and the shell 10 certain distance is arranged, think that draining pump 20 provides certain vibrational degrees of freedom space.The vibrational energy of draining pump 20 obtains discharging on the one hand in free space, can the oneself consume the partial vibration energy, on the other hand because the soft connection between draining pump 20 housings 21 and the washing machine shell 10, vibrational energy is absorbed by beam 30 bufferings, can not be directly delivered on the washing machine shell 10, therefore can reduce finally to be delivered to the vibration on the washing machine shell 10, reduce vibrating noise.
In the present embodiment, beam 30 specifically can be fixed on the base plate 12 of shell 10, because the vibration that is delivered on the base plate 12 is less, so expand to the also corresponding minimizing of the vibration of shell 10 side plates, the excessive noise of having avoided resonance to produce.
As shown in Figure 3, the beam in the present embodiment 30 preferably includes shell connecting portion 31 and pump connecting portion 32.Shell connecting portion 31 is fixed on the shell 10, and pump connecting portion 32 is fixedlyed connected with the housing 21 of draining pump 20, and as shown in Figure 4, and pump connecting portion 32 is formed on the shell connecting portion 31.Two parts of beam 30 can connect after the one-body molded or independent moulding, can increase the distance between draining pump 20 and the shell 10 on the one hand, also can further reduce to be delivered to the vibration of shell 10 on the other hand.
Further, be formed with fixing hole 23 and grafting bar 24 on the housing 21 of draining pump 20, fixing hole 23 is set on the projection 33 of pump connecting portion 32, and grafting bar 24 is plugged in the recess 34 of pump connecting portion 32.This structure is fixed by the mutual grafting between draining pump 20 and the beam 30, can improve the fixedly stability of draining pump 20, the damage of avoiding draining pump 20 vibratory impulses to be caused.The socket direction of fixing hole 23 and projection 33, and preferably has set angle between the grafting direction of grafting bar 24 and recess 34, this set angle is not equal to zero degree, preferably equal 90 degree, can make the grafting between draining pump 20 housings 21 and the beam 30 more firm, when draining pump 20 vibrations, can provide the supporting role power of a plurality of directions for draining pump 20.In addition, as shown in Figure 4, fixing hole 23 and grafting bar 24 preferably in abutting connection with being provided with, strengthen stability with same beam 30 grafting.The quantity of beam 30 can be one, also can be a plurality of, and for example, the quantity of beam 30 is three, has both guaranteed the requirement of stability maintenance, reduces making of beam 30 again as far as possible and is used for reducing cost.In the practical application, also can independently use the structure of fixing hole 23 or grafting bar 24 to connect draining pump 20 and beam 30.
Fixed form between beam 30 and the shell 10 has multiple, for example screw mode, riveted joint etc., and present embodiment is specifically as follows the grafting fixed form, is plugged on shell connecting portion 31 in the hole of washing machine shell 10 correspondences, the assembly and disassembly of being more convenient for.Beam 30 can adopt multiple can making the material that cushioning effect is played in vibration, for example, beam 30 is preferably Rubber shock-absorbing pad, can suppress the transmission of the vibration of draining pump 20 motors 22 generations to shell 10, thereby the vibration that reduces shell 10 reduces noise.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
