Embodiment 1

[0050] Such asfigure 1 As shown, the present embodiment provides a water purifier with zero stale water output function of the present invention, comprising: booster pump 1, RO filter element 2, pure water tank 3, return valve 5, check valve 6, pumping Liquid pump 7, first water outlet valve 10 and first water inlet valve 9;

[0051] The water outlet of the booster pump 1 is connected to the water inlet of the RO filter element 2, the pure water outlet of the RO filter element 2 is respectively connected to the pure water outlet 4 of the water purifier and the water inlet of the pure water tank 3, and the water outlet of the pure water tank 3 is connected to the pure water of the water purifier Port 4 is connected; after the return valve 5 is connected to the one-way valve 6, one end is connected to the water inlet of the booster pump 1, and the other end is connected to the pure water port of the RO filter element 2; the opening direction of the one-way valve 6 is from the RO ...

Embodiment 2

[0063] Such as figure 2 As shown, this embodiment provides a water purifier with a zero-age water output function of the present invention, and the water purifier in this embodiment is an improvement based on Embodiment 1:

[0064] On the basis of the water path of the water purifier in Embodiment 1, a second water outlet valve 8 is connected between the water outlet of the suction pump 7 and the pure water outlet 4 of the water purifier.

[0065] see image 3 , when it is necessary to supply pure water at normal temperature, this embodiment also provides a method for controlling the zero-age water output of the water purifier, including:

[0066] Start booster pump 1 and suction pump 7, open return valve 5 and second water outlet valve 8, close first water inlet valve 9 and first water outlet valve 10; The pure water tank 1 flows out from the pure water port 4 of the water purifier through the action of the pump 7, that is, pure water is supplied through the pure water tan...

Embodiment 3

[0071] Such as Figure 4 As shown, the present embodiment provides a water purifier with zero stale water output function of the present invention, and the water purifier in this embodiment is improved on the basis of Embodiment 2:

[0072] The upper end and the lower end in the pure water tank 3 are respectively a high liquid level sensing device HL and a low water level sensing device LL. The high liquid level sensing device HL and the low water level sensing device LL in this implementation may be liquid level sensors.

[0073] Setting via high level sensing HL and low level sensing LL, see Figure 5 , this embodiment also provides a method for controlling water storage in a pure water tank of a water purifier, including:

[0074] When the liquid level in the pure water tank 3 is lower than the low water level sensing device LL, according to the feedback of the low water level sensing device LL, start the booster pump 1, open the return valve 5, close the first water inle...

Abstract

The invention discloses a water purifier with a zero stale water output function and a zero stale water output control method thereof. The water purifier comprises a booster pump, an RO filter core, a pure water tank, a reflux valve, a one-way valve, a liquid sucking pump, a first water outlet valve and a first water inlet valve, wherein the water outlet of the booster pump is connected with the water inlet of the RO filter core, the pure water port of the RO filter core is respectively communicated with the pure water port of the water purifier and the water inlet of the pure water tank, the water outlet of the pure water tank is communicated with the pure water port of the water purifier, after the reflux valve is connected with the one-way valve, one end is connected with the water inlet of the booster pump, and the other end is connected with the pure water port of the RO filter core, the opening direction of the one-way valve is from the pure water port of the RO filter core to the water inlet of the booster pump, the liquid suckingpump is connected between the water outlet of the pure water tank and the pure water port of the water purifier, a first water inlet valve is connected between the pure water port of the RO filter core and the water inlet of the pure water tank, and a first water outlet valve is connected between the pure water port of the RO filter core and the pure water port of the water purifier. According to the water purifier, the problem that the TDS value of pure water which is just discharged after a period of time interval is relatively high is solved, and the supply quality of the pure water is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a water purifier that outputs pure water without stale water output, and a method for controlling the zero stale water output of the water purifier. Background technique [0002] The traditional reverse osmosis water purifier (RO water purifier) ​​prepares 50 gallons of pure water per day. With the increase of people's demand for pure water, the water production capacity of the RO water purifier (measuring the amount of pure water prepared per day) has increased from 400 Gallons to 800 gallons, or even more than 1,000 gallons, RO water purifiers are more and more popular among consumers due to their fast water output and high water production capacity. [0003] In the RO water purifier, the reverse osmosis (Reverse Osmosis, RO) membrane is the core component of the water purifier. When the RO water purifier is working, the pure water dissolved total solids (TDS) at t...
