In order to facilitate the distinction between the purified water in the purified water tank 2 and the purified water in the cold tank 3, the purified water in the purified water tank 2 is called warm water and the purified water in the cold tank 3 is called cold water.

The cold tank in the related art is generally provided with a warm water cavity and a cold water cavity, that is to say, the cold tank in the related art is used for storing warm water and cold water, so that the whole volume of the cold tank is large, and the miniaturization of water treatment equipment is not facilitated. In the waterway system 100 of the water treatment device of the embodiment of the utility model, the cold tank 3 in the related technology is replaced by two independent containers, namely the water purifying tank 2 and the cold tank 3, the cold tank 3 is only used for storing cold water, the volume of the cold tank 3 is effectively reduced, the water purifying tank 2 is used for storing warm water, the water purifying tank 2 and the cold tank 3 are two independent containers, the arrangement of components in the waterway system 100 is facilitated, and the space occupied by the waterway system 100 as a whole is reduced, so that the volume of the water treatment device can be reduced, and the miniaturization of the water treatment device is facilitated.

In some embodiments, the water outlet component 4 is provided with a water outlet, the first water outlet pipeline 21 and the second water outlet pipeline 31 are both communicated with the water outlet, when the first water outlet pipeline 21 is conducted and the second water outlet pipeline 31 is disconnected, warm water in the water purifying tank 2 can be discharged from the water outlet, and when the second water outlet pipeline 31 is conducted and the first water outlet pipeline 21 is disconnected, cold water in the cold tank 3 can be discharged from the water outlet.

In some further embodiments, the control valve module 6 is configured to control the opening degrees of the first and second water outlet lines 21 and 31 so that the waterway system 100 can control the ratio of the discharged warm water and cold water to adjust the temperature of the purified water discharged from the water discharge port.

In some other embodiments, the water outlet part 4 is provided with a plurality of water discharge ports, and the first water outlet pipeline 21 and the second water outlet pipeline 31 are respectively communicated with different water discharge ports, so that the waterway system 100 can discharge warm water alone, discharge cold water alone, discharge warm water and cold water simultaneously, and the warm water and the cold water do not affect each other.

In some embodiments, waterway system 100 further includes a first transfer pump 22, first transfer pump 22 being coupled to an outlet of clean water tank 2, first transfer pump 22 being coupled to first water outlet line 21 and second water outlet line 31, respectively.

The first delivery pump 22 is further connected to the second water outlet pipeline 31, that is, the first delivery pump 22 can pump the purified water in the purified water tank 2 to the second water outlet pipeline 31 to provide power for the water outlet of the second water outlet pipeline 31, so as to ensure the stability of the water outlet of the second water outlet pipeline 31.

In some embodiments, the first transfer pump 22 is connected to the second water outlet line 31 via the cold tank 3.

That is, the first transfer pump 22 communicates with the clean water tank 2 and the cold tank 3, respectively, so that the first transfer pump 22 can transfer the warm water in the clean water tank 2 into the cold tank 3. When the second water outlet pipeline 31 is in a disconnected state, the first delivery pump 22 works to deliver warm water in the clean water tank 2 into the cold tank 3, so that the cold tank 3 can be supplemented with water; when the second water outlet pipeline 31 is in a conducting state, the first delivery pump 22 works to deliver the warm water in the clean water tank 2 into the cold tank 3 so as to push the cold water in the cold tank 3, power the discharge of the cold water, and ensure the stability of the cold water discharged by the waterway system 100.

In the second state, the switching valve 61 opens the circulation circuit and the second water outlet line 31 is turned on, so that the cold water in the cold tank 3 stops circulating and is discharged through the second water outlet line 31.

In some specific embodiments, the switching valve 61 is configured as a three-way valve and has a first port, a second port, and a third port.

The second circulation pump 34 and the switching valve 61 are both disposed on the second water outlet pipe 31, and the switching valve 61 is located between the second circulation pump 34 and the water outlet member 4.

When the switching valve 61 is in the first state, the first port is communicated with the second port, so that the circulation loop is conducted and the second water outlet pipeline 31 is disconnected; when the switching valve 61 is in the second state, the first port is communicated with the third port, so that the circulation circuit is disconnected and the second water outlet pipeline 31 is conducted.

Through the technical scheme, the waterway system 100 can discharge cold water, warm water and hot water, so that the requirements of users on drinking water with different temperatures are met, and the practicability of the waterway system 100 is improved.

In some embodiments, the water outlet component 4 is provided with a water outlet, the first water outlet pipeline 21, the second water outlet pipeline 31 and the third water outlet pipeline 91 are all communicated with the water outlet, and when the first water outlet pipeline 21 is conducted, the second water outlet pipeline 31 and the third water outlet pipeline 91 are disconnected, the warm water in the clean water tank 2 can be discharged from the water outlet; when the second water outlet pipeline 31 is connected and the first water outlet pipeline 21 and the third water outlet pipeline 91 are disconnected, cold water in the cold tank 3 can be discharged from the water discharge port; when the third water outlet line 91 is turned on and the first water outlet line 21 and the second water outlet line 31 are disconnected, the hot water in the hot tank 9 can be discharged from the water discharge port.

In some other embodiments, the water outlet part 4 is provided with a plurality of water discharge ports, and the first water outlet pipeline 21, the second water outlet pipeline 31 and the third water outlet pipeline 91 are respectively communicated with different water discharge ports, so that the waterway system 100 can discharge warm water alone, cool water alone, hot water alone, and warm water, cool water and hot water simultaneously.

In some embodiments, the control valve module 6 includes: the first control valve 62 and the second control valve 63, the first control valve 62 is connected in series with the first water outlet pipeline 21 to control the on-off of the first water outlet pipeline 21, and the second control valve 63 is connected in series with the third water outlet pipeline 91 to control the on-off of the third water outlet pipeline 91.

In some embodiments, the hot tank 9 is located below the fresh water tank 2 in the vertical direction. Because the hot tank 9 is communicated with the clean water tank 2, the hot tank 9 is positioned below the clean water tank 2, so that the warm water in the clean water tank 2 can directly flow into the hot tank 9 under the action of gravity, other equipment is not required to be used for conveying the warm water in the clean water tank 2 to the hot tank 9, the waterway system 100 is simplified, and the cost of the waterway system 100 is reduced.

In some embodiments, the water outlet of the clean water tank 2 is disposed at the bottom of the clean water tank 2, and the water outlet of the clean water tank 2 is connected to the hot tank 9 through a pipeline, so that water in the clean water tank 2 can flow into the hot tank 9 under the action of gravity, that is, as long as water is in the clean water tank 2, water is also in the hot tank 9, so that the risk of dry heating of the heating device in the hot tank 9 is effectively reduced, and the safety of the waterway system 100 is improved.

In some embodiments, the hot tank 9 is provided with a second vent communicating with the first inlet 25 of the fresh water tank 2 via a second communication pipe 92, the fresh water tank 2 being at atmospheric pressure.

When the second control valve 63 is closed and the water in the fresh water tank 2 flows to the hot tank 9, the gas in the hot tank 9 enters the fresh water tank 2 through the second communicating pipe 92 to ensure that the air pressure in the hot tank 9 is not excessively high and the water replenishment of the hot tank 9 is normally performed.

In some further embodiments, the damper plug 8 is connected in series to the second communication pipe 92, so that the stability of the gas flow in the second communication pipe 92 is ensured.

When the second control valve 63 is closed and the water in the fresh water tank 2 flows to the hot tank 9, the gas in the hot tank 9 enters the fresh water tank 2 through the second communicating pipe 92, and at this time, the gas in the hot tank 9 may drive part of the hot water to enter the fresh water tank 2 through the second communicating pipe 92, so that the water temperature in the fresh water tank 2 is higher. To avoid this, in some embodiments, a first chamber 23 and a second chamber 24 are provided separately in the fresh water tank 2, the first chamber 23 being provided with an inlet communicating with the filtration module 1, the first chamber 23 being also connected to the cold tank 3.

When the hot water enters the clean water tank 2 through the second communicating pipe 92, the hot water enters the second chamber 24 and is separated from the warm water in the first chamber 23, and the hot water is independently cooled in the second chamber 24, so that the direct contact with the warm water is avoided, and the condition that the temperature of the warm water is influenced by the hot water is improved.

In some embodiments, the first air inlet 25 is located at the bottom of the second chamber 24, and the second chamber 24 is located above the hot tank 9. When the second control valve 63 is closed and the water in the clean water tank 2 flows to the hot tank 9, the gas in the hot tank 9 carries part of the hot water into the second chamber 24, and when the pressure in the hot tank 9 is balanced, the hot water in the second chamber 24 can return to the hot tank 9 under the action of gravity, so that the waste of water resources is avoided.

In some embodiments, the top of the second chamber 24 communicates with the first chamber 23 such that both the first chamber 23 and the second chamber 24 are at atmospheric pressure.

The utilization rate of the first transfer pump 22 is improved, and the structure of the waterway system 100 is simplified.

When the first control valve 62 and the second control valve 63 are closed and the switching valve 61 is in the first state, the first transfer pump 22 operates to transfer warm water in the first chamber 23 to the cold tank 3 to replenish water to the cold tank 3. The first transfer pump 22 is also connected to the hot tank 9, and when the first transfer pump 22 drives the warm water in the first chamber 23 to move to the cold tank 3, the hot water in the hot tank 9 is also subjected to the pushing pressure from the first transfer pump 22. Also because the second control valve 63 is closed, hot water in the hot tank 9 enters the second chamber 24 through the second communication pipe 92.

In order to avoid that too much hot water enters the second chamber 24, the hot water in the second chamber 24 overflows to the first chamber 23 to affect the temperature of the warm water. The first water level detecting member is disposed in the second chamber 24, and when the first water level detecting member detects that the liquid level in the second chamber 24 reaches the set height, the first delivery pump 22 stops working, thereby avoiding the overflow of the hot water in the second chamber 24 to the first chamber 23.

After the first transfer pump 22 stops working, the pushing force of the first transfer pump 22 to the hot tank 9 disappears, the hot water in the second chamber 24 returns to the hot tank 9 again under the action of gravity, and if the water in the cold tank 3 needs to be replenished, the first transfer pump 22 can be used for replenishing the water in the cold tank 3 again. That is, the cooling tank 3 is replenished with water by repeatedly starting and stopping the first transfer pump 22.

Tap water enters the PAC filter element 13 for one-time filtration after passing through the pressure reducing valve 11 and the water leakage protector 12, coarse impurities are filtered, and then enters the water inlet electromagnetic valve 14 and the booster pump 15, and the positions of the water inlet electromagnetic valve 14 and the booster pump 15 are arranged behind the PAC filter element 13 so as to prevent the water inlet dirt from damaging the parts of the water inlet electromagnetic valve 14 and the booster pump 15.
