Problems solved by technology

[0003] However, there will be such a problem: Generally, after the drainage is completed, the amount of water in the pump housing of the drainage pump is less, and there will be a certain amount of air. When the drainage pump enters water again, if the air in the pump housing cannot be discharged, it will always Hold in the pump casing, if there is a lot of air in the pump casing, if the drainage operation is performed, the pressure at the outlet of the drainage pump will be low, and the non-return piece cannot be flushed, resulting in the inability to drain water and causing serious consequences
[0004] At present, there are generally two drainage methods for drainage pumps on the market: one is to adjust the structure and speed of the drainage pump. When the water enters, a certain amount of gas will be held in the pump casing, and the air will be slowly discharged when the water is drained, but the air must be ensured. In the case of existence, the outlet pressure of the pump casing is also sufficient to open the non-return piece, otherwise the drainage cannot be performed. The problem with this method is that the exhaust process is slow and the drainage pressure and flow are not high when there is gas; the other is that in the drainage pump A small hole is opened on the top of the pump casing. When the drainage pump enters water, as the liquid level in the pump casing rises slowly, the air in the pump casing will be discharged through the small hole on the top, but when the drainage pump is working, the water in the pump casing will And the food residue will be shot out through the small hole and returned to the dishwasher (specifically, the water cup of the dishwasher), which will release the pressure in the pump casing and reduce the pressure of the water outlet. In addition, the kitchen residue may also block the small hole

Abstract

The invention belongs to the field of washing equipment, and particularly relates to a drainage pump of washing equipment and the washing equipment with the same. The drainage pump of the washing equipment comprises a pump case, a water inlet and a water outlet, wherein the water inlet and the water outlet are formed in the pump case. The region, close to the edge of the pump case, in the pump case is a high-pressure region in the pump case when the drainage pump works, a vent hole is formed in the pump case, and the vent hole is located between the center of the pump case and the high-pressure region. After washing is completed, the drainage pump is started, an impeller in the drainage pump rotates, liquid in the pump case moves to the edge of the pump case, meanwhile, air in the pump case is gathered to the middle region of the pump case, then the air is exhausted through the vent hole, along with the exhaust process of the air, external water enters the pump case, the water of the pump case becomes more but the air becomes less, along with increase of the water amount in the pump case, the drainage capacity is gradually improved, finally the pressure of the water outlet is highenough to jack a non-return piece away, and therefore smooth drainage is achieved.

Description

technical field [0001] The invention belongs to the field of washing equipment, and in particular relates to a drainage pump of the washing equipment and the washing equipment having the same. Background technique [0002] Household appliances such as dishwashers and washing machines need to be drained during and after the washing process. In order to prevent siphoning of the drainage pipes, anti-siphon structures are generally installed on the drainage pipes. In electrical appliances, a one-way flow control device is also required after the drain pump. Taking the dishwasher as an example, there is usually a non-return piece between the drain pump of the dishwasher and the anti-siphon structure. The drain pump stops working, and the backflow of water in the anti-siphon structure presses the non-return sheet, preventing sewage from flowing back into the inner cavity of the dishwasher. [0003] However, there will be such a problem: Generally, after the drainage is completed...
