Description

Technical Field

[0001] The utility model relates to the field of water purifier design, in particular to a water channel plate for a water purifier. Background Art

[0002] Existing water purifiers have a single filtration mode, meaning that a single filter element and valve can only perform a single function. This single water path can no longer meet users' needs for multiple water output modes. Therefore, a prior art water purifier (Announcement No.: CN220664931U, Announcement Date: March 26, 2024) discloses a water purifier that redirects raw water to filter through different filter elements, achieving different water output effects and meeting diverse user needs.

[0003] However, in the above solution, the water first passes through the coarse filter element and then passes through one of the fine filter elements for filtration. The two fine filter elements are switched by a water channel switching valve. When one fine filter element is in the filtering state, the other fine filter element will be in the discharge state. After switching, the functions of the two fine filter elements are opposite. This water purification method requires switching the water channel for filtering and discharge at regular intervals, and it is impossible to discharge the concentrate from two filter elements at the same time. Moreover, after the water channel is switched, since some water flow still remains in the original water channel, there will be a problem of untimely switching, resulting in the TDS value just after switching not meeting the standard. It is necessary to switch the water channel and drain the water for a period of time before drinking water with the corresponding purification effect can flow out, which will result in a small amount of water waste. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0005] A water purifier waterway plate comprises a plate body, wherein the upper end of the plate body is formed with a raw water inlet, a purified water outlet, a waste water outlet and a pure water outlet;

[0006] The raw water inlet is connected to a pre-composite filter element, the water inlet of the pre-composite filter element is connected to a raw water TDS probe, and the water outlet of the pre-composite filter element is connected to the purified water outlet;

[0008] The first pure water inlet is connected to a pure water TDS probe, which is connected to a post-carbon filter element. The post-carbon filter element is provided with a second sewage outlet and a second pure water outlet. The second sewage outlet flows back into the water pump, and the second pure water outlet is connected to the pure water outlet.

[0009] Furthermore: a plurality of water channels are provided in the plate body, and the raw water inlet, clean water outlet, waste water outlet, pure water outlet, pre-composite filter element, water pump, OR membrane filter element and post-carbon filter element are respectively connected through the water channels.

[0010] Further: the plate body includes an upper plate and a lower plate, the upper plate and the lower plate are spliced and assembled with each other, the upper ends of multiple water channels on the lower plate are formed with a first plug-in tube, and the lower ends of multiple water channels on the upper plate are formed with a second plug-in tube, the first plug-in tubes are plugged and installed in the second plug-in tubes in a one-to-one correspondence, a sealing ring is connected between the first plug-in tube and the second plug-in tube, and the raw water inlet, clean water outlet, waste water outlet and pure water outlet are all formed at the upper end of the upper plate.

[0011] Furthermore: a water leakage protection valve and a pressure relief protection solenoid valve are connected in sequence between the raw water inlet and the pre-composite filter element.

[0012] Furthermore: a clean water one-way valve, a clean water high-pressure switch, a clean water outlet control solenoid valve and a micro-nano bubble generator are connected in sequence between the water outlet of the pre-composite filter element and the clean water outlet.

[0013] Furthermore: a first water inlet solenoid valve is connected between the raw water TDS probe and the water pump.

[0014] Furthermore: a first pure water one-way valve is connected between the first water outlet of the OR membrane filter element and the pure water TDS probe.

[0015] Furthermore: a sewage discharge solenoid valve is connected between the first sewage discharge port and the wastewater outlet of the OR membrane filter element.

[0016] Furthermore: a second pure water one-way valve, a pure water high-pressure switch and a pure water outlet control solenoid valve are sequentially connected between the second pure water inlet and the pure water outlet of the post-carbon filter element.

[0017] Furthermore: a second water inlet solenoid valve and a third pure water one-way valve are connected in sequence between the second sewage outlet of the post-carbon filter element and the water pump, and the second sewage outlet flows back into the water pump through the second water inlet solenoid valve and the third pure water one-way valve.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. Tap water enters the plate body of the water purifier through the raw water inlet and is divided into two pipelines. One is directly transported to the pre-filter element for preliminary filtration and then output from the purified water outlet. This pipeline can achieve preliminary filtration of tap water and obtain daily water;

[0020] 2. A raw water TDS probe is installed at the second pipeline to detect the TSD value of tap water. The water is then pumped into the OR membrane filter element by a water pump. After being filtered by the OR membrane filter element, it is output from the first pure water outlet. The pure water TDS probe is used to test the TSD value of the pure water at this time. The two TSD values can be directly output and displayed to inform the user to achieve filtration comparison. The pure water is then further purified through the post-carbon filter element to obtain drinking water.

[0021] 3. When flushing and cleaning the OR membrane filter element and the post-carbon filter element, close the pure water outlet and open the wastewater outlet. The water pump will drive the water flow to clean the OR membrane filter element. The water that cannot pass through the OR membrane filter element will be discharged from the first sewage outlet and then discharged from the wastewater outlet. After the water flows through the OR membrane filter element but cannot pass through the post-carbon filter element, the water will be output from the second sewage outlet. The second sewage outlet will flow back into the water pump and then return to the wastewater outlet for discharge.

[0022] The utility model does not need to set a switching valve to switch the pipeline, and can directly discharge the concentrate by opening the wastewater outlet. The pure water outlet will not be affected when discharging the concentrate. Similarly, the drinking water output from the pure water outlet will not be affected by the discharge of the concentrate. Two TSD probes are used to detect the values of the water source before and after filtration, and then effectively determine whether the filtered drinking water is drinkable. When the TSD value of the drinking water exceeds the standard, the wastewater outlet can be opened to discharge the concentrate for a period of time. When the discharge of the concentrate cannot make the TSD value return to the standard value, the corresponding filter element needs to be replaced.
