Problems solved by technology
[0003] At present, most of the drum washing machines use top drainage. When the drainage pump is at full load or no load, the noise is very small and can be ignored; but when the drainage pump is at half load, due to the flapping of the residual water by the blades, there will be a lot of noise
This noise is discontinuous, the sense of hearing is extremely poor, and it is easy to cause complaints
[0004] At present, the noise reduction methods of drainage pumps are mostly by adding vibration isolation pads between the drainage pump and the box, adding rubber blocks on the blades, and adding discharge holes in the pump casing, etc., but none of them can solve the drainage from the source. The reason for the noise of the pump at half load: the blades beat the residual water, so the noise reduction effect is relatively limited

The invention discloses a drainage pump for a drum washing machine and a drum washing machine having the same. The drainage pump includes: a pump casing provided with drainage blades; a motor connected to the drainage blades , When the water level in the pump casing is higher than the maximum height of the drainage blade, the motor works to drive the drainage blade to rotate, and when the water level in the pump casing is lower than the maximum height of the drainage blade , The motor stops working. The drainage pump according to the present invention generates less noise when draining, thereby improving the user's experience.
Description
technical field [0001] The invention relates to the field of household appliances, in particular to a drain pump for a drum washing machine and a drum washing machine with the drain pump. Background technique [0002] With the progress of the times, people have higher and higher requirements for the noise quality of washing machines, and the vibration and noise performance of the machine has become an important indicator of product quality. [0003] At present, most front-loading washing machines use top drainage. When the drainage pump is at full load or no load, the noise is negligible; however, when the drainage pump is at half load, the blades beat the residual water, making a lot of noise. This noise is discontinuous, the sense of hearing is extremely poor, and it is easy to cause complaints. [0004] At present, the noise reduction methods of drainage pumps are mostly by adding vibration isolation pads between the drainage pump and the box, adding rubber blocks on the...
