Water purification device, control device thereof, and water purification control method of water purification device

Abstract

The invention discloses a water purification device. The water purification device comprises an original water tank, a purified water tank, and a waste water tank; a filtering device, wherein the filtering device is connected with the original water tank via a first pipeline, is connected with the waste water tank via a second pipeline, and is connected with the purified water tank via a third pipeline; a control device, wherein the control device comprises a booster pump arranged on the first pipeline; a water level detection module used for detecting water level of the purified water tank; a control unit which is connected with the booster pump and the water level detection module respectively. According to the water purification device, when water level of the purified water tank is lower than a first preset water level, the booster pump is controlled by the control unit to start to work; and when water level of the purified water tank is higher than a second preset water level, the booster pump is controlled by the control unit to stop working, wherein the second preset water level is higher than the first preset water level. The water purification device is capable of avoiding frequent starting of the booster pump, prolonging service life of the booster pump effectively, and reducing waste water emission. The invention also discloses a control device of the water purification device, and a water purification control method of the water purification device.

Description

technical field [0001] The invention relates to the technical field of domestic appliances, in particular to a water purification device, a control device for the water purification device, and a water purification control method for the water purification device. Background technique [0002] In the existing clean drinking machines, the clean water tank is usually only provided with a full water detection device. When the whole machine is working, once the full water detection device detects that the water in the clean water tank is not full, the booster pump starts immediately, so that As a result, the booster pump starts frequently, which affects the life of the booster pump, and there are hidden dangers. Moreover, every time the booster pump works, the filter element assembly must be flushed, resulting in a large amount of waste water being discharged from the drinking machine, and the user needs to frequently pour out waste water. Simultaneously, the user will not only...

Problems solved by technology

[0002] In the existing clean drinking machines, the clean water tank is usually only provided with a full water detection device. When the whole machine is working, once the full water detection device detects that the water in the clean water tank is not full, the booster pump starts immediately, so that Caused the booster pump to start frequently, affecting the life of the booster pump, and there are hidden dangers

Moreover, every time the booster pump works, the filter element assembly must be flushed, resulting in a large amount of waste water discharged from the drinking machine, and the user needs to frequently pour out waste water

At the same time, in the process of using the water purifier, the user not only needs to add water to the original water tank, but also pours out waste water after the waste water tank is full, which brings inconvenience to the user.

[0003] In addition, after the water tank of the water purifier is used for a long time, there may be bacteria on the inner wall of the water tank, which will cause the floating ball to stick to the inner wall of the water tank, and the normal water level detection cannot be realized
