Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1 As shown, the embodiment of the utility model provides a pure hot and precise mixed water system, including a filter element 1, a distribution device 3, a hot water circuit 17, a normal temperature water adjustable circuit 15 and a normal temperature water circuit 16. The filter element 1 is connected to the raw water. When the filter element 1 contains multiple filter elements, multi-stage filtration can be performed. The output pure water is respectively input into the hot water circuit 17, the normal temperature water adjustable circuit 15 and the normal temperature water circuit 16. The hot water circuit 17 can output hot water, the normal temperature water circuit 16 can output normal temperature water, and the normal temperature water adjustable circuit 15 can output adjustable normal temperature water. The precise mixed water system can be applied to the under-kitchen water purifier, and can also be applied to other water purifiers such as table water purifiers. When applied to the under-kitchen water purifier, the filter element is connected to the tap water through a pipeline, and the heating water circuit 17, the normal temperature water circuit 16 and the normal temperature water adjustable circuit 15 are connected to the water outlet device 13. The water outlet device 13 can be a faucet, so that the faucet can output hot water and normal temperature water.

[0028] Specifically, the filter element 1 includes at least a fine filter element, which is an RO filter element or a nanofiltration filter element or other; the distribution device 3 is a distribution valve or other coordinated arrangement such as a multi-way valve, a pressure reducing valve, etc. The first water inlet of the distribution valve and the first water outlet of the distribution valve are located upstream of the water inlet of the fine filter element. It should be noted that upstream refers to the first flow along the waterway flow direction, and downstream refers to the last flow along the waterway flow direction.

[0029] When the filter element 1 only includes a fine filter element, the first water inlet of the distribution valve and the first water outlet of the distribution valve are both located upstream of the water inlet of the fine filter element, and the water flowing into the first water inlet of the distribution valve flows out from the first water outlet of the distribution valve, and the water outlet of the fine filter element is connected to the second water inlet of the distribution valve. That is, in the flow direction, the water passes through the first water inlet of the distribution valve, the first water outlet of the distribution valve, the fine filter element, and the second water inlet of the distribution valve in sequence.

[0030] When the filter element 1 includes a pre-filter element and a fine filter element for filtering in sequence, when the first water inlet of the distribution valve is located upstream of the pre-filter element, the first water outlet of the distribution valve is located upstream of the pre-filter element; or when the first water inlet of the distribution valve is located between the pre-filter element and the fine filter element, the first water outlet of the distribution valve is located between the pre-filter element and the fine filter element; the water outlet of the fine filter element is connected to the second water inlet of the distribution valve. That is, in the flow direction, it passes through the first water inlet of the distribution valve, the first water outlet of the distribution valve, the pre-filter element, the fine filter element, and the second water inlet of the distribution valve in sequence, or it passes through the pre-filter element, the first water inlet of the distribution valve 3, the first water outlet of the distribution valve, the fine filter element, and the second water inlet of the distribution valve in sequence.

[0031] When the filter element 1 includes a fine filter element and a post-filter element that filter in sequence, the first water inlet and the first water outlet of the distribution valve are located upstream of the fine filter element, and the water outlet of the post-filter element is connected to the second water inlet of the distribution valve. That is, in the flow direction, the water passes through the first water inlet of the distribution valve, the first water outlet of the distribution valve, the fine filter element, the post-filter element, and the second water inlet of the distribution valve in sequence.

[0032] When the filter element 1 includes a pre-filter element, a post-filter element and a fine filter element, the pre-filter element, the fine filter element and the post-filter element are filtered in sequence, and the pre-filter element, the post-filter element and the fine filter element are all compositely arranged or partially compositely arranged or separately arranged. It should be noted that composite arrangement means that at least two filter elements are located in the same filter bottle, and separate arrangement means that each is arranged in a separate filter bottle. For example, the filter element can be a composite filter element in which a pre-filter element, a fine filter element and a post-filter element are composited in the same filter bottle; the filter element can also be a multi-stage filter element matched with an independent pre-filter element, an independent fine filter element and an independent post-filter element; the filter element can be a multi-stage filter element in which two of the pre-filter element, the fine filter element and the post-filter element are composited and the other filter element is independently arranged. When the first water inlet of the distribution valve is located upstream of the pre-filter, the first water outlet of the distribution valve is located upstream of the pre-filter, and the second water inlet of the distribution valve is connected to the water outlet of the post-filter; when the first water inlet of the distribution valve is located between the pre-filter and the fine filter, the first water outlet of the distribution valve is located between the pre-filter and the fine filter, and the second water inlet of the distribution valve is connected to the water outlet of the post-filter. That is, in the flow direction, the water passes through the first water inlet of the distribution valve, the first water outlet of the distribution valve, the pre-filter, the fine filter, the post-filter, and the second water inlet of the distribution valve in sequence; or, the water passes through the pre-filter, the first water inlet of the distribution valve, the first water outlet of the distribution valve, the fine filter, the post-filter, and the second water inlet of the distribution valve in sequence.

[0033] In this embodiment, the filter element 1 is a composite filter element including a pre-filter, an RO filter element and a post-filter element, and has a first water inlet, a first water outlet, a second water inlet, a second water outlet and a wastewater outlet. The first water inlet and the first water outlet correspond to the water inlet and the water outlet of the pre-filter element, the second water inlet corresponds to the water inlet of the RO filter element, and the second water outlet corresponds to the water outlet of the post-filter element. The first water inlet of the composite filter element is connected to water, the first water outlet is connected to the first water inlet of the distribution valve through the water inlet solenoid valve 2, the first water outlet of the distribution valve is connected to the second water inlet of the composite filter element through the booster pump 4, and the wastewater generated after filtration by the RO filter element is discharged through the wastewater valve 14 downstream of the wastewater outlet of the composite filter element. The pure water filtered by the composite filter element is connected from the second water outlet of the composite filter element to the second water inlet of the distribution valve. A pure water TDS temperature sensing probe 5 is also provided between the second water outlet of the composite filter element and the second water inlet of the distribution valve. The pure water TDS temperature sensing probe 5 is a TDS water quality detector with a temperature sensing probe, which can judge the water quality and water temperature.

[0034] The water outlet downstream of the last filter element in the filter element 1 is divided into three paths, which are respectively connected to the water inlet of the normal temperature water path 16, the water inlet of the hot water path 17 and the second water inlet of the distribution device 3.

[0035] In this embodiment, the second water outlet of the composite filter element is connected to the normal temperature water circuit 16 for providing normal temperature drinking water. Specifically, the second water outlet of the composite filter element is connected to the normal temperature water solenoid valve 6 in the normal temperature water circuit 16, and the normal temperature water circuit is switched on and off by the normal temperature water solenoid valve 6. The normal temperature water solenoid valve 6 is connected to the water inlet of the one-way valve 7 to control the flow direction of the normal temperature water, and the water outlet of the one-way valve 7 is connected to the water outlet device.

[0036] In this embodiment, the second water outlet of the composite filter element is connected to the hot water circuit 17 to provide hot water. Specifically, the second water outlet of the composite filter element is connected to the water inlet of the hot water tank water supply valve 8 of the hot water tank water supply valve 17, and the water outlet of the hot water tank water supply valve 8 is connected to the hot water tank 9 to store a large amount of hot water and keep it warm. The water outlet of the hot water tank 9 is connected to the second flow control device to adjust the flow rate, and the water outlet of the second flow control device is connected to the water outlet device to output hot water. The hot water tank 9 is also provided with a hot water tank 9 NTC to monitor the hot water temperature; the hot water tank 9 is provided with an exhaust port, and the exhaust port is connected to the water outlet device 13.

[0037] The second water outlet of the distribution device 3 is connected to the normal temperature water adjustable water circuit 15 to output adjustable normal temperature water. Specifically, the second water outlet of the distribution valve is connected to the water inlet of the first flow control device of the normal temperature water adjustable water circuit 15, and the water outlet of the first flow control device is connected to the water outlet device 13. In this embodiment, the normal temperature water adjustable water circuit 15 and the normal temperature water circuit 16 merge at the end of the water circuit and are connected to the water outlet device 13 together.

[0038] In this embodiment, the water outlet device 13 is an intelligent electric display faucet that can outlet hot water, normal temperature water and mixed water, and can also display the current outlet water temperature.

[0039] In this embodiment, the second flow control device in the hot water circuit 17 is a speed-adjustable hot water pump 10, and the first flow control device in the normal temperature water adjustable circuit 15 is a negative pressure switch 11 and a water outlet pump 12 connected in sequence. The flow rate of the normal temperature water adjustable circuit 15 is adjustable in the following way: the speed-adjustable water outlet pump 12 generates suction to change the rear end of the negative pressure switch 11 into a negative pressure state. At this time, the diaphragm in the negative pressure switch 11 is lifted by the atmospheric pressure, thereby opening the water circuit in the machine. By adjusting the rotation speed of the water outlet pump 12, different suction forces are generated to act on the rear end of the negative pressure switch 11, so that the sealing diaphragm of the negative pressure switch 11 is lifted to different heights, thereby achieving different normal temperature water flow rates. It should be noted that the speed-adjustable hot water pump 10 can be replaced by a combination of a water outlet pump without a flow adjustment function and a flow adjustment element.

[0040] When the user selects the middle gear water temperature, the corresponding amount of water needs to be provided according to the corresponding hot water temperature and normal temperature water temperature. The water flow rate of the heat tank 9 is controlled by the second flow control device in the hot water circuit, and the normal temperature water flow rate is controlled by the first flow control device in the normal temperature water adjustable water circuit, so as to mix the required hot water temperature for use. The excess pure water produced by the filter element forms a back pressure at the water inlet end of the flow control device, and is redistributed back to the front end of the water inlet of the RO filter element through the distribution valve, thereby avoiding the situation where the RO filter element causes the water flow at the faucet outlet to be too small, thereby avoiding adverse effects on the operation function of the whole machine, and replacing the traditional water tank, the pure water is produced and heated immediately, realizing the function of fresh hot water and reducing costs.

[0041] Working mode of the utility model:

[0042] 1. Water outlet mode:

[0043] (1) Normal temperature water: Normal temperature water circuit is realized to ensure that the large flux is not affected;

[0044] (2) Hot water: hot water is stored and output through the heat tank 9 to ensure a large flow of water;

[0045] (3) Water outlet at other intermediate temperatures: The hot water circuit and the adjustable normal temperature water circuit are combined to discharge water at the same time to form a mixed water circuit. The temperature of the normal temperature water is monitored by the pure water TDS temperature sensor 5, and the water temperature in the heat tank 9 is monitored by the heat tank 9 NTC. Then, the water outlet ratio of the normal temperature water and the hot water is adjusted by the negative pressure switch 11, the adjustable speed water outlet pump 12, and the adjustable speed hot water pump 10, so as to achieve the purpose of mixed water at the set temperature. The four variables affected by the mixed water temperature are the normal temperature water temperature and flow rate, and the hot water temperature and flow rate are all controllable, so as to achieve precise temperature control of the mixed water outlet temperature, and at the same time, a large flow rate can be guaranteed.

[0046] 2. Water flow direction:

[0047] like Figure 1 As shown, water enters the first water inlet of the composite filter element, is filtered by the pre-filter element in the composite filter element, and then flows out from the first water outlet of the pre- and post-composite filter elements, then enters the first water inlet of the distribution valve, and flows out through the first water outlet of the distribution valve, enters the RO filter element in the composite filter element through the booster pump 4 for filtration, and the waste water generated by the filtration is discharged through the waste water outlet and waste water solenoid valve of the composite filter element; the pure water is filtered by the RO filter element and the post-filter element, and output from the second water outlet of the composite filter element.

[0048] The second water outlet of the composite filter element is divided into three paths downstream. One path is the normal temperature water solenoid valve 6 and the one-way valve 7 to discharge water to the faucet, and normal temperature water can be discharged; one path is the hot water tank replenishment valve 8, the hot water tank 9, and the speed regulating hot water pump 10 to discharge water to the faucet, and hot water can be discharged; one path enters the second water inlet of the distribution valve, flows out from the second water outlet of the distribution valve, passes through the negative pressure switch 11 and the water outlet pump 12 to the faucet 13, and normal temperature water of different flow rates can be discharged. When discharging hot water of different temperatures, the normal temperature water flow rate can be adjusted by the negative pressure switch 11 and the water outlet pump 12, and the hot water can be adjusted by the speed regulating hot water pump 10, and the excess pure water at the front end of the water inlet of the negative pressure switch 11 is redistributed back to the front end of the water inlet of the RO filter element in the composite filter element through the distribution valve, reducing the adverse effects on the whole machine.

That is, each component in the waterway system can be selected to be located in the housing or outside the housing, etc., according to the situation.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
