Washing machine, setting method for drainage pressure thresholds, drainage control method and drainage control system

Abstract

The invention relates to a washing machine, a setting method for drainage pressure thresholds, a drainage control method and a drainage control system. The washing machine comprises a casing, a washing drum and a drain pipe. The washing drum is arranged in the casing. The drain pipe connected to the bottom of the washing drum extends out of the casing. A fluid driving member is arranged on the drain pipe, and a pressure sensor is arranged in the drain pipe. The fluid driving member determines whether to drive fluids in the drain pipe according to pressure parameters sensed by the pressure sensor. When the water pressure in the drain pipe is large, it is difficult to discharge water through the gravity, so that the fluid driving member drives the fluids in the drain pipe to be discharged out; when the pressure in the drain pipe is small, the drainage requirements can be met only through the gravity, so that the fluid driving member does not drive the fluids in the drain pipe, and the fluids are naturally discharged out. The problems of low drainage efficiency and low drainage rate of the washing machine can be solved, high energy consumption is avoided, and a large quantity of energy resources are saved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a washing machine, a method for setting a drainage pressure threshold, a drainage control method and a system. Background technique [0002] With the continuous improvement of the quality of life, there are more and more various electrical appliances in people's lives. As a traditional household appliance, the washing machine has gradually replaced people's laundry habits, and its functions are becoming more and more diverse. At present, the drainage of washing machines mostly depends on the natural drainage of gravity, which causes the drainage efficiency to be fast at first and then slow, and the duration is too long, resulting in extremely low drainage efficiency, and the drainage rate needs to be improved; some washing machines are equipped with drainage pumps for drainage. However, the drainage pump is running during the entire drainage process, resulting in hi...

Problems solved by technology

At present, the drainage of washing machines mostly depends on the natural drainage of gravity, which causes the drainage efficiency to be fast at first and then slow, and the duration is too long, resulting in extremely low drainage efficiency, and the drainage rate needs to be improved; some washing machines are equipped with drainage pumps for drainage. However, the drainage pump is running during the entire drainage process, resulting in high energy consumption and wasting a lot of energy, or it is operated by the user's intervention operation. The drainage process is affected by user habits and many accidental factors, sometimes resulting in extremely low drainage efficiency. Low, sometimes resulting in high energy consumption and waste of energy
