Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

As shown in FIG. 1, in one embodiment, a water purification and hydration system 10 is provided, comprising:

a filter assembly 11;

a water inlet of the purified water tank 12 is communicated with a purified water outlet of the filter assembly 11;

a spray head 13, wherein the spray head 13 is arranged between the spray head 13 and the purified water tank 12 so that the spray head 13 can spray water into the purified water tank 12;

a cleaning passage 14, a first end of the cleaning passage 14 is communicated with the inlet of the spray head 13, a second end of the cleaning passage 14 is communicated with the water outlet of the purified water tank 12, a first driving part 141 is arranged on the cleaning passage 14, and the first driving part 141 is used for providing driving force for the water flow in the cleaning passage 14 to flow from the second end to the first end.

According to the purified water drinking system 10, the spray head 13 is arranged, and the purified water in the purified water tank 12 is used for washing the purified water tank 12, so that the cleanliness of the purified water tank 12 can be kept even if the purified water drinking system 10 is used for a long time, and the problem of water health is effectively avoided. And because pure water in the fresh water tank 12 is used for the rinsing, the degree of contamination of the fresh water tank 12 due to the rinsing process is not increased. Specifically, when the water needs to be washed, the first driving member 141 is activated to pump the pure water in the pure water tank 12 into the spray head 13, and spray the pure water from the spray head 13 into the pure water tank 12 to wash and clean the inner wall surface of the pure water tank 12.

Further, to ensure that the flushing process is performed properly, the amount of pure water in the fresh water tank 12 during the flushing process is greater than the amount required to fill the passage from the outlet of the fresh water tank 12 to the spray head 13. In other words, after the first driving member 141 is activated, pure water in the pure water tank 12 is sucked into the passage between the outlet of the pure water tank 12 and the spray head 13, and at least the remaining water can be continuously sprayed, so that the cleaning process is continuous, and the first driving member 141 can continuously pump water.

Further specifically, as shown in fig. 1, in one embodiment, the spray head 13 is provided in the fresh water tank 12. The water sprayed from the spray head 13 can be washed to the inner wall surface of the clean water tank 12.

Alternatively, in other embodiments, the spray head 13 is located outside the clean water tank 12, but when the spray head 13 sprays water, the water sprayed by the spray head 13 can flush into the clean water tank 12 to flush and clean the inner wall surface of the clean water tank 12.

Further, as shown in fig. 1, in one embodiment, a top cover of the fresh water tank 12 is provided with a pressure relief through hole 121. Thereby ensuring that the pressure in the water purifying tank 12 is balanced with the external air pressure and ensuring that the water inlet and outlet processes are carried out smoothly.

Further, in one embodiment, as shown in fig. 1, the drinking water purification system 10 further includes a water outlet nozzle 15, and the water outlet nozzle 15 is communicated with the water outlet of the water purification tank 12. When a user needs to take water, the pure water in the pure water tank 12 is introduced into the water outlet nozzle 15 and is discharged from the water outlet nozzle 15.

More specifically, as shown in fig. 1, in one embodiment, the water outlet nozzle 15 communicates with the cleaning passage 14 through a first multi-way valve 151, and the first driving member 141 is located between the first multi-way valve 151 and the water outlet of the clean water tank 12.

When the purified water tank 12 is required to be flushed or when water is required to be supplied to a user, the first driving member 141 is in an open state, so that the purified water in the purified water tank 12 is discharged along a predetermined path.

For example, when supplying water to a user, the first multi-way valve 151 is switched to a state in which the water outlet nozzle 15 is connected to the cleaning passage 14, and at this time, the space between the nozzle 13 and the outlet of the purified water tank 12 is in a cut-off state. When the first driving member 141 is started, pure water in the pure water tank 12 flows into the cleaning passage 14, and then flows to the water outlet nozzle 15 through the first multi-way valve 151.

When the clean water tank 12 needs to be flushed, the first multi-way valve 151 is switched to a state where the water outlet nozzle 15 and the cleaning passage 14 are closed, and the spray head 13 and the water outlet of the clean water tank 12 are communicated. When the first driving member 141 is started, pure water in the pure water tank 12 enters the cleaning passage 14 and then flows to the spray head 13 through the first multi-way valve 151.

Of course, alternatively, in other embodiments, the water outlet nozzle 15 may be separately connected to the water outlet of the fresh water tank 12 through another passage, for example, a water intake passage provided with a second driving member is provided between the water outlet nozzle 15 and the water outlet of the fresh water tank 12. And the water taking process of a user is controlled by controlling the switch of the second driving piece.

Further, in one embodiment, as shown in fig. 1, a heating element 1411 is further disposed on the cleaning path 14, and the heating element 1411 is located between the first multi-way valve 151 and the water outlet of the fresh water tank 12.

When it is necessary to sterilize the purified water tank 12, the heating member 1411 is activated so that the water reaching the spray head 13 is high temperature water. Of course, if the user needs to take hot water, the heating element 1411 may also be heated so that the temperature of the water discharged from the water outlet nozzle 15 meets the user's needs.

Specifically, in some embodiments, the heating member 1411 is a heat generating pipe that communicates with the cleaning path 14, and water flowing through the cleaning path 14 flows through the heat generating pipe. When the heating tube is in an open state, water flowing through the heating tube is heated.

Further specifically, in some embodiments, the filtration assembly comprises a reverse osmosis membrane cartridge.

Further, in one embodiment, a low water level detector is disposed in the fresh water tank 12 and located at a predetermined allowable washing water level in the fresh water tank 12, and the low water level detector is electrically connected to the first driving member 141.

When the low water level detecting member detects that the water level in the water tank is reduced to the preset washing water level, if the washing is required, the first driving member 141 is started.

It should be noted that when the low water level detecting member detects that the water level in the water tank is lowered to the preset washing water level, the washing process is not necessarily performed. For example, if the rinsing process is performed at a certain time interval T, the first driving member 141 starts to pump the pure water in the pure water tank 12 into the spray head 13 only when the time interval from the last rinsing reaches T and the low water level detecting member detects that the water level in the water tank is lowered to the preset rinsing water level. Alternatively, the rinsing process may be performed only when the user is not getting water. Only when an instruction that the user does not take water is obtained and the low water level detection part detects that the water level in the water tank is reduced to the preset cleaning water level, the first driving part 141 starts to pump the pure water in the pure water tank 12 into the spray head 13.

Further, in one embodiment, as shown in fig. 2, there are a plurality of the fresh water tanks 12 and a plurality of the spray nozzles 13, and the fresh water tanks 12 and the spray nozzles 13 are provided in one-to-one correspondence. One of the nozzles 13 is capable of spraying pure water into the corresponding pure water tank 12.

Two of the clean water tanks 12 may alternately receive the pure water filtered by the filter assembly 11, and when one of the clean water tanks 12 is filled with the pure water, the other clean water tank 12 may be used to store the pure water.

Further, as shown in fig. 2, in one embodiment, the outlet of each of the fresh water tanks 12 is provided with an outlet branch passage 122, and each of the outlet branch passages 122 can be selectively communicated with the cleaning passage 14. The inlet of each spray head 13 is provided with a water inlet branch passage 131, and each water inlet branch passage 131 can be selectively communicated with the cleaning passage 14.

When pure water is not present in a certain pure water tank 12 and a washing or disinfecting process is required to be performed on this pure water tank 12, the pure water in the pure water tank 12 in which the pure water is stored may be introduced into the spray head 13 corresponding to the pure water tank 12 that is required to be washed or disinfected. For example, if the clean water tank 12 to be washed or sterilized is the clean water tank a, the clean water tank 12 storing pure water is the clean water tank B. The outlet branch passage 122 provided at the outlet of the purified water tank B is communicated with the cleaning passage 14, and the inlet branch passage 131 provided at the inlet of the nozzle 13 corresponding to the purified water tank a is communicated with the cleaning passage 14, so that when the first driving member 141 is activated, the purified water in the purified water tank B can be pumped to the nozzle 13 corresponding to the purified water tank a, and the purified water tank a is washed or sterilized. Of course, when the user takes water, the pure water in the pure water tank B may be directly introduced into the water outlet nozzle 15.

More specifically, in one embodiment, as shown in fig. 2, a second end of the cleaning path 14 is provided with a second multi-way valve 142, and other water ports of the second multi-way valve 142 are respectively communicated with the plurality of water outlet branch paths 122. When it is necessary to connect one of the clean water tanks 12 to the cleaning passage 14, the second multi-way valve 142 is switched to a state in which the water port communicating with the water outlet branch passage 122 corresponding to the clean water tank 12 is connected to the cleaning passage 14.

Optionally, in another embodiment, a water outlet switch valve is disposed on the water outlet branch passage 122. The on-off state of each water outlet branch passage 122 and the cleaning passage 14 is controlled by controlling the on-off process of each water outlet switch valve.

Similarly, in one embodiment, a third multi-way valve 143 is disposed at a first end of the cleaning passage 14, and other water ports of the third multi-way valve 143 are respectively communicated with the plurality of water inlet branch passages 131.

Also optionally, in another embodiment, a water inlet switch valve is disposed on the water inlet branch passage 131.

Further, as shown in fig. 2, in one embodiment, the pure water outlet of the filter assembly 11 is provided with a pure water main passage 111, and the water inlet of each of the fresh water tanks 12 is provided with a pure water branch passage 123, and each of the pure water branch passages 123 can be selectively communicated with the pure water main passage 111.

Pure water produced by filtration by the filter module 11 can be selectively stored in each of the fresh-water tanks 12.

Further, in one embodiment, a fourth multi-way valve 1111 is disposed at an end of the pure water main passage 111 away from the pure water outlet, and other water ports of the fourth multi-way valve 1111 are respectively communicated with the pure water branch passages 123.

And the fourth multi-way valve 1111 can selectively control which pure water branch passage 123 is communicated with the pure water main passage 111.

Also, in another embodiment, a pure water switch valve is provided on the pure water branch passage 123.
