Embodiment 1

[0029] This embodiment provides a water system of a water purifier, including a controller, a water inlet 1, a water outlet 2, a water inlet valve 3 located between the water inlet 1 and the water outlet 2, a water pump 4, and a filtration system 5 A flow switch 6 is arranged between the end of the filter system 5 and the water outlet 2, and the controller is used to control the opening of the water pump 4 and the opening of the water inlet valve 3 when the flow switch 6 is closed. When the flow switch 6 is turned off, the water pump 4 is controlled to stop and the water inlet valve 3 is closed.

[0030] Such as figure 1 As shown, the water inlet 1 and the water outlet 2 are sequentially connected in series with the water inlet valve 3, the water pump 4, the filtration system 5, and the flow switch 6. The water outlet 2 is provided with a faucet. When the user turns on the faucet, the water flows through the flow switch 6. The filter system 5 can work normally. At this time, ...

Embodiment 2

[0032] This embodiment provides a control method for the waterway system of the water purifier, which is applied to the waterway system of the water purifier provided in the above embodiment. In one embodiment, as figure 2 As shown, the control method includes the following steps:

[0033] the faucet is turned on;

[0034] Obtain the status of the flow switch;

[0035] When the flow switch is closed, the control water pump is turned on and the water inlet valve is turned on;

[0036] When the flow is disconnected, the water pump is controlled to stop and the water inlet valve is closed.

[0037] In the control method provided by this embodiment, when the flow switch is turned off, it means that no water passes through the flow switch, which may be due to water shortage or failure of the water purifier. Affects the statistics of filter element life.

[0038] On the basis of the above embodiments, in one embodiment, when the flow switch is closed, the following steps are fu...

Embodiment 3

[0044] This embodiment provides a control device for a water purifier waterway system, which is applied to the water purifier waterway system provided in Example 1. In one embodiment, the control device includes:

[0045] an acquisition unit, configured to acquire the state of the flow switch;

[0046] The judging unit is configured to control the water pump to turn on and the water inlet valve to open when the flow switch is closed, and control the water pump to stop and the water inlet valve to close when the flow switch is turned off.

[0047] In the control device provided in this embodiment, when the flow switch is disconnected, it means that no water passes through the flow switch, which may be due to water shortage or failure of the water purifier. Affects the statistics of filter element life.

[0048] On the basis of the foregoing embodiments, in one embodiment, the control device further includes:

[0049] The acquisition subunit is used to acquire the state of the...

Abstract

The invention relates to the technical field of water purifiers, in particular to a water purifier waterway system, a control method and a control device. The water purifier waterway system comprisesa controller, a water inlet, a water outlet, a water inlet valve located between the water inlet and the water outlet, a water pump and a filtering system, wherein a flow switch is arranged between the tail end of the filtering system and the water outlet, and the controller is used for controlling the water pump to be opened and the water inlet valve to be opened when the flow switch is closed and controlling the water pump to be stopped and the water inlet valve to be closed when the flow switch is disconnected. When the flow switch is closed, it shows that water flows through the flow switch, the filtering system can normally operates, and then the water pump is controlled to be turned on, the water inlet valve is controlled to be opened, and the filtering system continuously produces water; when the flow switch is turned off, it shows that no water flows through the flow switch, water shortage or failure of the water purifier occurs possibly, the water pump is controlled to be turned off, the water inlet valve is controlled to be closed, idling of the water pump can be avoided, and therefore statistics of the service life of the filter element is prevented from being affected.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a waterway system, a control method and a control device of a water purifier. Background technique [0002] Water purifiers or filtration systems usually use a low-pressure switch to test the pressure of the water source as a condition for the water purifier or filtration system to open. When the low-pressure switch detects water, the water is produced normally. When the water pressure is too low or no pressure, the low-pressure switch If the water pressure cannot be detected, it will be judged that there is a lack of water, and the whole machine will stop running. In the prior art, in order to reduce the cost, some water purifiers cancel the low-pressure switch, which leads to the continuous idling of the water pump in the case of water shortage, which shortens the life of the water pump. At the same time, the life of the filter element is usually counted by the running ...
