Description
- The present invention relates to a drainage device of a household appliance, including a drainage channel connected to a water holding device and a drainage pump installed in the drainage channel, where the drainage pump includes a main body, a sewage outfall disposed on the main body, and a pump cover installed on the sewage outfall; and the present invention further relates to a household appliance having the drainage device.

FIG. 1 shows an existing washing machine 1 having adrainage device 2. Thedrainage device 2 includes adrainage channel 4 connected to awater holding barrel 3 and for conducting the washing water out of the washing machine 1. A drainage pump 5 is installed in thedrainage channel 4. Anauxiliary drainage pipe 6 is installed on thedrainage channel 4 between the drainage pump 5 and thewater holding barrel 3. The end of theauxiliary drainage pipe 6 is disposed with anend cover 7. When a user needs to clean the drainage pump 5, theend cover 7 is opened in advance and the sewage in thedrainage device 2 is discharged through theauxiliary drainage pipe 6. - The defects existing in the prior art are as follows. First, the position of the auxiliary drainage channel is relatively high, resulting in that the sewage cannot be thoroughly discharged, and therefore, when the user unscrews the pump cover, some sewage still flows out of a bump body to pollute the floor. Second, the auxiliary drainage channel in the prior art needs to extend from a front panel of the washing machine, so a specific space needs to be reserved on the front panel so as to set specific parts. In addition, since the
auxiliary drainage pipe 6 is connected to thedrainage channel 4 and theauxiliary drainage pipe 6 has some sewage, the sewage may pour out of theauxiliary drainage pipe 6 when theend cover 7 is opened, which may soil the hands of the user. Moreover, the openedend cover 7 is stained with some sewage, which easily pollutes the floor, and the end cover may be lost or forgotten to be re-installed on the auxiliary drainage pipe again when the user cleans the drainage pump. - The objective of the present invention is to provided an improved drainage device to overcome the defects in the prior art.
- For the above objective, the present invention adopts the following technical solution. A drainage device of a household appliance is provided, which includes a drainage channel connected to a water holding device, and a drainage pump installed in the drainage channel, where the drainage pump includes a main body, a sewage outfall disposed on the main body, and a pump cover installed on the sewage outfall. The main body includes a cavity connected to the drainage channel, a drainage notch connected to a bottom of the cavity is disposed on the main body, and an auxiliary drainage pipe is disposed on the pump cover. The pump cover has at least two rotation positions relative to the sewage outfall. On a first rotation position, an end surface of the pump cover opposite to the sewage outfall seals the drainage notch, and on a second rotation position, the auxiliary drainage pipe is in communication with the drainage notch.
- As an improvement to the above technical solution, the drainage notch is disposed on an end wall of the sewage outfall opposite to the pump cover and the notch is located at an edge right below the sewage outfall relative to a gravity direction.
- As an improvement to the above technical solution, a flexible sealing gasket is located between the sewage outfall and the pump cover, and a through hole in communication with the drainage notch is disposed on the sealing gasket.
- Preferably, the sealing gasket has a positioning device for positioning and limiting rotation thereof and is in cooperation with a positioning connection device on the sewage outfall.
- Preferably, the pump cover has a knob.
- Preferably, on the first and the second rotation positions of the pump cover relative to the sewage outfall, the pump cover seals the sewage outfall, and on a third rotation position, the pump cover is detachable from the sewage outfall.
- The present invention further provides a household device including the above drainage device.
- The beneficial effects produced after adopting the above technical solution are as follows. Compared with the prior art, since the position of the auxiliary drainage pipe is much lower and is close to a minimum discharge level, the residual sewage in the pump can be discharged more thoroughly, and no sewage would flow out when a user opens the pump cover after using the auxiliary drainage pipe for pre-drainage. In addition, since the auxiliary drainage pipe is disposed on the pump cover, it is not required to specifically reserve a space for the auxiliary drainage pipe on a front panel of a washing machine, enabling the assembly structure simpler. Meanwhile, the connection and disconnection between the auxiliary drainage pipe and the drainage notch can be achieved by rotating the pump cover, and pre-drainage and opening the drainage pump can be implemented merely by operating one part. Therefore, the operation is simple, convenient and clean, and it is not easy for a user to forget to seal the auxiliary drainage pipe.
- The invention is now explained in further detail with reference to the Figures of the drawing attached. In particular,
-
FIG. 1 is a schematic view of an existing washing machine; -
FIG. 2 is a schematic view of an improved washing machine; -
FIG. 3 is an exploded view of a drainage pump of a washing machine; -
FIG. 4 is a view of the drainage pump after being installed in the washing machine ofFIG. 3 ; and -
FIG. 5 is a sectional view of the drainage pump in the washing machine ofFIG. 4 along an A-A direction. - As shown in
FIG. 2 andFIG. 3 , awashing machine 10 has adrainage device 12. Thedrainage device 12 includes adrainage channel 16 connected to awater holding barrel 14 and for conducting the washing water out of thewashing machine 10. Adrainage pump 18 is installed in thedrainage channel 16. Thedrainage pump 18 has amain body 20. Acavity 22 connected to thedrainage channel 16 is formed in themain body 20. Thecavity 22 has asewage outfall 24. Apump cover 26 is installed on thesewage outfall 24 so as to seal or open thesewage outfall 24. A sealinggasket 28 made of a flexible material is installed between thepump cover 26 and thesewage outfall 24. The sealinggasket 28 has apositioning bump 29 which is in cooperation with apositioning notch 31 disposed on thesewage outfall 24, so as to implement the positioning and avoid that the sealing gasket rotates together with thepump cover 26. - The
sewage outfall 24 has anend wall 30 opposite to thepump cover 26. Adrainage notch 32 is disposed on theend wall 30 and is in communication with thecavity 22, and thenotch 32 is located at an edge right blow thesewage outfall 24 relative to a gravity direction. A throughhole 33 in communication with the drainage notch is disposed on the sealinggasket 28. In addition, thepump cover 26 has aknob 34 for a user to operate and is further disposed with anauxiliary drainage pipe 35. Thepump cover 26 can rotate with respect to thesewage outfall 24. Generally in a fastening position of thepump cover 26, anend surface 36 of thepump cover 26 opposite to thesewage outfall 24 seals the throughhole 33 of the sealinggasket 28, so as to seal thedrainage notch 32, and further seal thesewage outfall 24 at the same time. When thepump cover 26 rotates, with respect to thesewage outfall 24, to a pre-drainage position as shown inFIG. 4 and FIG. 5 , theauxiliary drainage pipe 35 is in communication with thedrainage notch 32 and the throughhole 33 of the sealinggasket 28, and then the sewage in thecavity 22 can be discharged through theauxiliary drainage pipe 35. At this time, thepump cover 26 still seals thesewage outfall 24 and the sewage cannot flow out of other places except theauxiliary drainage pipe 35. When no sewage flows out of theauxiliary drainage pipe 35, a user can continue to rotate thepump cover 26 to a certain angle so that thepump cover 26 is separated from thesewage outfall 24, and then the user can further clean or maintain thedrainage pump 18.
