Abstract
The invention relates to an improved residual water releasing structure of a washing machine drainage pump, which comprises a manual drainage pipe, a drainage pipe and a drainage pump. An opening matched with the manual drainage pipe is arranged at the bottom part of the outer cover of the drainage pump, and the opening is inserted into an inlet end of the manual drainage pipe; furthermore, the opening arranged at the bottom part of the outer cover of the drainage pump and the inlet end of the manual drainage pipe adopt a thread matching structure. The improved residual water releasing structure of the washing machine drainage pump provided by the invention can completely drain out the residual water in the drainage pump in time, and effectively reduce the noise generated by the drainage pump when being operated; and can avoid the impaction to the normal operation caused by the freezing of the residual water in the drainage pump when the machine is under the freezing temperature.
Description
Technical field
The present invention relates to washing machine, particularly the residual water discharging structure of drainage pump of washing machine.
Background technology
The residual water discharging structure of existing drainage pump of washing machine, see also Fig. 1, its manual drainage pipe 3 be arranged on drainpipe 2 under, draining pump 1 is arranged between the two, be used for the sewage behind the washing machine cleaning clothes is discharged body as early as possible, the major defect of its existence is: because manual drainage pipe 3 residing positions are incorrect, ending the period near draining, be not as the firm incipient stage, to be full of water body in the draining pump 1, around the blade of draining pump 1, there is air, can sends very big noise during the blade rotation of draining pump 1 like this; Because the position of manual drainage pipe 3 is than the water line height of draining pump 1, so the water reality of finishing in the draining pump 1 after laundry, the draining is not drained, wherein there is residual water 4, if machine is to be under the freezing temperature, then this residual water 4 may freeze, and the blade of draining pump 1 frozen, influence the normal use of washing machine, even the blade of draining pump 1 is not frozen in, might clash into the ice that residual water 4 is formed, send huge noise, even the blade of draining pump 1 may be damaged.
Summary of the invention
The residual water discharging structure that the purpose of this invention is to provide a kind of improved drainage pump of washing machine solves the residual water problems in the draining pump, reduces noise, overcomes the existing shortcoming of existing product.
For achieving the above object, solution of the present invention is: the residual water discharging structure of improved drainage pump of washing machine comprises manual drainage pipe, drainpipe, draining pump, the cover bottom portion of this draining pump is provided with the opening that matches with the manual drainage pipe, and the arrival end of this manual drainage pipe inserts this opening.
Further, the arrival end of the opening of the cover bottom portion setting of described draining pump and this manual drainage pipe is a thread matching structure.
Owing to adopted such scheme, the residual water discharging structure of improved drainage pump of washing machine of the present invention can in time be got rid of the residual water in the draining pump fully, the noise that draining pump is sent when effectively reducing operation; In the time of under machine is in freezing temperature, avoid influencing the normal use of washing machine because of the residual water freezing in the draining pump.
Description of drawings
Fig. 1 is the schematic cross-section of existing washing machine drainage structure;
Fig. 2 is the schematic cross-section of the residual water discharging structure of an embodiment of the present invention.
The specific embodiment
See also Fig. 2, the residual water discharging structure of improved drainage pump of washing machine comprises manual drainage pipe (not showing on the figure), drainpipe 22, draining pump 23, enclosing cover 24 bottoms of this draining pump are provided with the opening 25 that matches with the manual drainage pipe, and the arrival end of this manual drainage pipe inserts this opening.
Further, the opening 25 of the cover bottom portion setting of described draining pump is thread matching structures with the arrival end of this manual drainage pipe 21, secure and reliable connection, extruded by pressure even under the bigger situation of pressure, also can effectively prevent this manual drainage pipe 21, so the situation that opening 25 that residual water is provided with from this cover bottom portion leaks can not take place.
Owing to adopted such scheme, the residual water discharging structure of improved drainage pump of washing machine of the present invention can in time be got rid of the residual water in the draining pump fully, the noise that draining pump is sent when effectively reducing operation; In the time of under machine is in freezing temperature, avoid influencing the normal use of washing machine because of the residual water freezing in the draining pump.
The above-mentioned description to embodiment is can understand and apply the invention 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 invention is not restricted to the embodiment here, those skilled in the art should be within protection scope of the present invention for improvement and modification that the present invention makes according to announcement of the present invention.
