The water purifiers of the embodiments of the present application are described below with reference to FIGS. 1 to 22 . The water purifiers disclosed in the embodiments of the present application may be household water purifiers, such as under-kitchen water purifiers.

As shown in FIGS. 1-6 , the water purifier according to the first embodiment of the present application includes: a filtering system 100 , a heating system 200 and a water pump 510 .

The filtration system 100 has a raw water inlet 101 and a purified water outlet 105, and the raw water inlet 101 can be directly or indirectly connected to a raw water pipe, for example, the raw water pipe can be a tap water pipe. The raw water to be filtered flows into the filtration system 100 from the raw water inlet 101 , and then flows out pure water from the purified water outlet 105 after being filtered.

The heating system 200 has a water inlet 221 and a water outlet 222. The water inlet 221 of the heating system 200 is connected to the water purification outlet 105 of the filtration system 100, and the water outlet 222 of the heating system 200 is connected to the first water supply outlet of the water purifier. The heating system 200 is used to heat the water flowing through the heating system 200 .

The water pump 510 is connected to the filtering system 100, and the water pump 510 is arranged upstream of the water purification outlet 105 of the filtering system 100. 510 is used to drive water out of the water outlet 222 of the heating system 200 .

In other words, in one of the working modes of the water purifier, the raw water flows into the filtration system 100 from the raw water inlet 101 of the filtration system 100 , and under the driving of the water pump 510 , it is filtered and then flows out pure water from the water purification outlet 105 of the filtration system 100 . Water, the pure water flowing out from the water purification outlet 105 of the filtration system 100 flows into the heating system 200 from the water inlet 221 of the heating system 200.

In other words, the filtered pure water flows into the heating system 200 from the lower part of the heating system 200 to be heated.

It can be understood that, after the pure water entering the heating system 200 is heated, the density of the hot water is relatively small and floats up, and the density of the cold water is relatively large and sinks.

In addition to driving the raw water to flow from the raw water inlet 601 to the purified water outlet 105 for filtering, the water pump 510 can also drive hot water to be discharged from the water outlet 222 of the heating system 200 .

In other words, the water pump 510 is both the driving pump of the filtering system 100 and the driving pump of the heating system 200 . The hot water in the embodiment of the present application is not extracted from the heating system 200 by designing an independent water pump, but is shared with the filtering system 100 . The water pump 510 forms a water pressure difference between the water inlet 221 and the water outlet 222 of the heating system 200, and pushes the upper hot water to the first water supply port of the water purifier through the water pressure difference, so that the introduction of external air can be avoided. The waterway of the water purifier prevents secondary pollution.

As shown in FIG. 1 , the return pipe 540 is connected between the clean water outlet 105 and the inlet of the water pump 510 . When the water purifier is just turned on, when the water pump 510 is working, the pure water from the water purification outlet 105 can be sucked into the water pump 510 again through the return pipe 540. The purified water can re-enter the filtration system 100 for at least one stage of filtration.

In other words, when the return pipe 540 is connected, the first cup of water with insufficient quality can be prevented from flowing out, and the quality of the water introduced into the filtration system 100 is enhanced, so that the quality of the purified water from the water purification outlet 105 of the filtration system 100 is higher. Especially for the first glass of water, by arranging the water return pipe 540, the quality of the first glass of water can be greatly improved.

According to the water purifier of the embodiment of the present application, the water purification and heating functions are integrated, and the water inlet 221 is arranged at the lower part of the heating system 200 and the water outlet 222 is arranged at the upper part of the heating system 200, and the push-type water outlet method of the water pump 510 is combined. , which can prevent the outside air from being introduced into the waterway of the water purifier and prevent secondary pollution.

The exhaust check valve 565 may be disposed between the exhaust valve 566 and the exhaust port 223 , or the exhaust valve 566 may be disposed between the exhaust check valve 565 and the exhaust port 223 .

In some embodiments, as shown in FIG. 1 , the water purifier may further include: a water return pipe 540 connected between the water purification outlet 105 and the inlet of the water pump 510.

When the water purifier is just turned on, when the water pump 510 is working, the pure water from the water purification outlet 105 can be sucked into the water pump 510 again through the return pipe 540. The purified water can re-enter the filtration system 100 for at least one stage of filtration.

In other words, when the return pipe 540 is connected, the first cup of water with insufficient quality can be prevented from flowing out, and the quality of the water introduced into the filtration system 100 is enhanced, so that the purified water of the water purification outlet 105 of the filtration system 100 has a higher quality. Especially for the first glass of water, by arranging the water return pipe 540, the quality of the first glass of water can be greatly improved.
