[0038] To enable those skilled in the art to better understand the solutions of this application, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0040] In one embodiment of this utility model, such as Figure 1 As shown, a multi-water quality mode integrated water purifier and heater is provided, including a water inlet port, a pre-filter 210, a booster pump 310, a reverse osmosis filter 220, a first one-way valve 510, a water supply switch valve 330, a first water tank 410 with a heater, and a first water pump 420, wherein the water outlet port of the first water pump 420 is configured to be connected to a water tap 600.

[0041] The integrated water purifier and heater also includes a microfiltration water bypass, which includes a flow regulating device 320 and a second one-way valve 520 connected in sequence. The inlet port of the flow regulating device 320 is connected to the outlet port of the pre-filter 210 or the outlet port of the booster pump 310, and the outlet port of the second one-way valve 520 is connected to the outlet port of the first one-way valve 510.

[0042] The integrated water purifier and heater also includes a normal temperature water outlet branch, which includes a water outlet switch valve 340. One end of the normal temperature water outlet branch is connected to the inlet port of the water replenishment switch valve 330, and the other end is connected to the outlet port of the first water pump 420. Specifically, the water replenishment switch valve 330 and the water outlet switch valve 340 can be solenoid valves.

[0043] In one specific embodiment, a pressure regulating valve 120 and an inlet solenoid valve 110 are sequentially provided on the inlet branch between the inlet port and the pre-filter 210. In addition to the pre-filter 210 and the reverse osmosis filter 220, the integrated water purifier and heat pump also includes a post-filter 230. The reverse osmosis filter 220 is connected to the post-filter 230 through a third one-way valve 530. Specifically, the third one-way valve 530 is located between the outlet port of the reverse osmosis filter 220 and the inlet port of the post-filter. The outlet port of the post-filter is connected to the inlet port of the first one-way valve 510. The integrated water purifier and heater also includes a TDS sensor 700 for detecting water quality. It is installed in the mixing water path of the outlet water path (i.e., RO water path) and the microfiltration water bypass path of the first one-way valve 510. The flow rate ratio of the RO water path and the microfiltration water bypass path can be adjusted according to the detection results of the TDS sensor. For example, if the detection data of the TDS sensor 700 exceeds the upper limit of the preset healthy range, the flow rate of the RO water path can be increased or the flow rate of the microfiltration water bypass path can be decreased; if the detection data of the TDS sensor 700 is lower than the lower limit of the preset healthy range, the flow rate of the RO water path can be decreased or the flow rate of the microfiltration water bypass path can be increased.

[0044] The first embodiment of this application is, for example... Figure 1 As shown, the flow regulating device 320 is a flow regulating valve, and its inlet port is connected to the outlet port of the booster pump 310.

[0045] In this embodiment, the integrated water purifier and heater allows the user to select the output water quality: the unit is equipped with an RO water quality selection button and a mixed water quality selection button. When the user presses the RO water quality selection button, the flow regulating valve ( Figure 1 The flow regulating device 320 in the middle is closed; when the user presses the mixed water quality selection key, the flow regulating valve ( Figure 1 When the flow regulating device 320 is opened, RO water filtered by the reverse osmosis filter 220 flows out from the first one-way valve 510, while micro-filtered water that has passed through the pre-filter 210 but not the reverse osmosis filter 220 flows out from the second one-way valve 520. Then, on one hand, the mixed water can enter the first water tank 410 through the water supply valve 330 and be heated into hot water. With the first water pump 420 turned on, the mixed water in the first water tank can flow out from the water outlet 600; on the other hand, the mixed water can also flow out from the water outlet 600 through the water outlet valve 340. The first water tank 410 has a certain capacity for water storage. When the liquid level in the first water tank 410 is lower than a certain height, the water supply valve 330 can be opened to maintain a certain amount of water in the first water tank 410.

[0046] The water purifier and heater in this embodiment allows the user to select the water quality: the unit is equipped with a normal temperature water outlet button, a medium temperature water outlet button, and a high temperature water outlet button. When the user presses the normal temperature water outlet button, the first water pump 420 is turned off (i.e., the first water tank 410 does not dispense water), and the water outlet switch valve 340 is opened, so that normal temperature water flows out from the water outlet faucet 600.

[0047] When the user presses the medium-temperature water outlet button, the first water pump 420 turns on (i.e., the first water tank 410 dispenses hot water), and the water outlet valve 340 turns on (dispenses room temperature water). The medium-temperature water obtained after mixing flows out from the water outlet 600.

[0048] When the user presses the high-temperature water outlet button, the water outlet switch valve 340 closes (no room temperature water is dispensed), the first water pump 420 turns on, and the heated high-temperature water in the first water tank 410 flows out from the water outlet 600.

[0049] In summary, users can select high-temperature mixed water by opening the flow regulating valve. Figure 1 The flow regulating device 320 and the first water pump 420 are connected. The outlet valve 340 is closed, and the water supply valve 330 is opened when the liquid level in the first water tank 410 is too low. Medium-temperature mixed water can be selected, i.e., the flow regulating valve is opened. Figure 1 The system includes a flow regulating device 320, a first water pump 420, and an outlet valve 340. The water supply valve 330 opens when the liquid level in the first water tank 410 is too low; alternatively, it can select to dispense ambient temperature mixed water by opening the flow regulating valve. Figure 1 The flow regulating device 320 and the outlet switch valve 340 are used to close the water supply switch valve 330 and the first water pump 420.

[0050] Users can also choose RO water at room temperature, i.e., by closing the flow regulating valve. Figure 1 The flow regulating device 320 is used, and the outlet valve 340 is opened, while the water supply valve 330 and the first water pump 420 are closed; alternatively, medium-temperature RO water can be selected, i.e., the flow regulating valve is closed. Figure 1 The flow regulating device 320 is used to open the first water pump 420 and the outlet valve 340 (provided there is no mixed water in the first water tank 410). The water replenishment valve 330 is opened when the liquid level in the first water tank 410 is too low; alternatively, high-temperature RO water can be selected, i.e., the flow regulating valve is closed. Figure 1 The flow regulating device 320 is activated, the first water pump 420 is turned on, and the outlet valve 340 is closed (provided that there is no mixed water in the first water tank). The water replenishment valve 330 is opened when the liquid level in the first water tank 410 is too low.

Specifically, the microfiltration bypass in this embodiment includes a zero-pressure valve 350, a flow regulating device 320, and a second check valve 520 connected in sequence.

[0052] Similar to the first embodiment, the integrated water purifier and heater can select high-temperature, medium-temperature, or room-temperature RO water or mixed mineral health water according to the user's needs, which will not be elaborated further.

[0053] The third embodiment of this application, for example Figure 3 As shown, unlike the first and second embodiments, the integrated water purifier and heat pump in this embodiment also includes a second water tank 430 without a heater and a second water pump 440 connected in sequence. The water outlet port of the second water pump 440 is connected to the water outlet port of the first water pump 420, that is, both are connected to the water tap 600.

[0054] See Figure 3 The first water tank 410 is used to store RO pure water, and the second water tank 430 is used to store mixed water. The water supply switch valve 330 is a three-way valve with a first port, a second port and a third port. The outlet port of the first one-way valve 510 is connected to the first port, the inlet port of the first water tank 410 is connected to the second port, and the inlet port of the second water tank 430 is connected to the third port.

[0055] When water is added to the first water tank 410 (RO pure water), the inlet port of the second water tank 430 is connected to the outlet port of the first one-way valve 510 (but not to the second one-way valve 520), that is, the first water tank 410 is not connected to the microfiltration water bypass: flow regulating valve ( Figure 3 The flow regulating device 320 in the middle is in the closed state, the first port of the three-way valve is connected to the second port, and the first port can be connected to the third port or not connected to the third port;

[0056] When water is added to the second water tank 420 (mixed mineral health water), the inlet port of the second water tank 430 is simultaneously connected to the outlet ports of the first one-way valve 510 and the second one-way valve 520: flow regulating valve ( Figure 3 The flow regulating device 320 is in the open state, and the first port of the three-way valve is connected to the third port, but the first port is not connected to the second port.

[0057] The third embodiment of the integrated water purifier and heat pump can also be customized to meet user needs, allowing the user to select high-temperature, medium-temperature, or room-temperature RO water, as well as medium-temperature or room-temperature mixed mineral health water.

[0058] Users can select medium-temperature mixed water by opening the flow regulating valve. Figure 3 The flow regulating device 320), the first port and the third port of the three-way valve are connected (i.e., the second water tank 430 is replenished with water), the first port and the second port are not connected (i.e., the first water tank 410 is not replenished with water), the first water pump 420 is in the open state, and at least one of the second water pump 440 and the outlet switch valve 340 is open; it is also possible to select room temperature mixed water, in two ways: Method 1, the second water pump 440 is opened, and the room temperature mixed water stored in the second water tank 430 flows out from the outlet faucet 600. When the liquid level in the second water tank 430 is lower than the preset height, the replenishment switch valve 330 is opened to replenish the mixed water in the second water tank 430; Method 2, the flow regulating valve ( Figure 3 The flow regulating device 320 and the outlet switch valve 340 in the middle are used to shut off the first water pump 420 and the second water pump 440. In this way, RO water and microfiltration water are mixed in the normal temperature outlet branch and then flow out from the outlet faucet 600.

[0059] Users can also choose RO water at room temperature, i.e., by closing the flow regulating valve. Figure 3 The flow regulating device 320 is used, and the outlet valve 340 is opened, while the water supply valve 330 and the first water pump 420 are closed; alternatively, medium-temperature RO water can be selected, i.e., the flow regulating valve is closed. Figure 3 The flow regulating device 320 is used to open the first water pump 420 and the outlet valve 340 (provided there is no mixed water in the first water tank). The water replenishment valve 330 is opened when the liquid level in the first water tank 410 is too low; alternatively, high-temperature RO water can be selected, i.e., the flow regulating valve is closed. Figure 3 The flow regulating device 320 is activated, the first water pump 420 is turned on, and the outlet valve 340 is closed (provided that there is no mixed water in the first water tank). The water replenishment valve 330 is opened when the liquid level in the first water tank 410 is too low.

[0060] In this embodiment, the pre-filter 210 is equipped with a sterilization module. RO pure water enters the first water tank 410, which has a heating function, reducing the rate of scaling. The second water tank 430 is equipped with a UV sterilization module, ensuring the cleanliness of the mixed mineral healthy water stored at room temperature even if the second water tank 430 does not have a heating function. This invention does not exclude the possibility that the second water tank 430 has a heating module.

[0061] The fourth embodiment of this application, for example Figure 4 As shown, unlike the third embodiment, see [link to embodiment]. Figure 4 The second water tank 430 is used specifically for storing RO pure water, and the first water tank 410 is used for storing mixed water, as detailed below:

[0063] When water is added to the second water tank 420 (RO pure water), the inlet port of the second water tank 430 is connected to the outlet port of the first one-way valve 510 (but not to the second one-way valve 520), that is, the second water tank 430 is not connected to the microfiltration water bypass: flow regulating valve ( Figure 4 The flow regulating device 320 in the middle is in the closed state, the first port of the three-way valve is connected to the second port, and the first port can be connected to the third port or not connected to the third port;

[0064] When water is added to the first water tank 410 (mixed mineral health water), the inlet port of the first water tank 410 is simultaneously connected to the outlet ports of the first one-way valve 510 and the second one-way valve 520: flow regulating valve ( Figure 4 The flow regulating device 320 is in the open state, and the first port of the three-way valve is connected to the third port, but the first port is not connected to the second port.

[0065] The fourth embodiment of the integrated water purifier and heater can also be configured to provide either room temperature RO water or room temperature, medium temperature, or room temperature mixed mineral water, depending on the user's needs.

[0066] The user can choose to dispense high-temperature mixed water by turning on the first water pump 420, causing the high-temperature mixed water stored in the first water tank 410 to flow out from the water outlet 600. When the liquid level in the first water tank 410 is lower than the preset height, the water replenishment valve 330 is opened to replenish the first water tank 410 with mixed water. The user can also choose to dispense medium-temperature mixed water by opening the flow regulating valve.

In this way, the RO water and the microfiltration water are mixed in the normal temperature outlet branch and then flow out from the outlet faucet 600.

[0067] Users can also choose RO water at room temperature, with the following two options: Option 1: Close the flow regulating valve ( Figure 4Method 1: Flow regulating device 320, water supply switch valve 340, and second water pump 440 are turned on, and RO pure water stored in second water tank 430 flows out from water outlet 600; Method 2: Close flow regulating valve, water supply switch valve 330 and first water pump 420, and open water outlet switch valve 340. In this way, RO water flows out from water outlet 600 after passing through normal temperature water outlet branch.

[0068] In this embodiment, the second water tank 430 is equipped with a UV sterilization module, so that even if the second water tank 430 does not have a heating function, the cleanliness of the RO pure water stored at room temperature can be ensured; the mineral health water mixed with RO water and microfiltration water enters the first water tank 410 with a heating function, which can improve the hot water output efficiency and hot water output flow rate; this utility model does not exclude the possibility that the second water tank 430 also has a heating module.
