Description

Technical Field

[0001] This utility model belongs to the field of drinking water equipment technology, and specifically relates to an integrated hot and cold water purifier under the sink. Background Technology

[0002] Under-sink water purifiers, also known as water purifiers, are usually installed in kitchen cabinets and connected to the faucet via pipes. When the user turns on the faucet, the under-sink water purifier filters the tap water into drinkable water.

[0003] For example, the under-sink water purifier disclosed in Chinese Patent Publication No. CN212632001U includes a primary filter, a secondary filter, and a tertiary filter. Each filter has a mounting base connected to its top, and the three mounting bases are arranged side-by-side. Each mounting base has an inlet and an outlet channel for the connected filter. The mounting base for the secondary filter also has a wastewater channel for the secondary filter. The water purifier has a flat overall design, allowing for easy installation in narrow spaces within a cabinet, thus filtering tap water (raw water) into purified water (filtered water) and supplying it to the faucet.

[0004] The above technical solution has the following drawbacks: This type of water purifier can only provide filtered room temperature water and cannot directly provide cold or hot water. Users need to manually heat or cool the purified water, which is not only cumbersome and difficult to meet users' water needs, but also reduces the frequency of use of the water purifier faucet, resulting in an unsatisfactory user experience. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a combined hot and cold water purifier under the sink. The technical problem to be solved by this utility model is: how to improve the ease of use of the under-sink water purifier.

[0006] The above-mentioned technical objectives of this utility model can be achieved through the following technical solutions: A combined hot and cold water purifier for under-sink use includes a frame, a cold water tank, a hot water tank, and a controller. An electromagnetic valve assembly is installed inside the frame. A housing is mounted on the frame, and pipe connectors are installed on the housing. Each pipe connector includes an inlet connector, a cold water connector, a hot water connector, and a drain connector. An inlet pipe connects the inlet connector to the electromagnetic valve assembly. The electromagnetic valve assembly supplies water to the cold water tank and the hot water tank respectively via two water supply pipes. A cold water outlet pipe connects to the cold water tank on the cold water connector, and a hot water outlet pipe connects to the hot water tank on the hot water connector. A drain valve is installed on the drain connector, and both the cold water outlet pipe and the hot water outlet pipe are connected to the drain valve. A refrigeration component is installed outside the cold water tank, and a heating component is installed on the hot water tank. The controller is electrically connected to the refrigeration component, the heating component, the electromagnetic valve assembly, and the drain valve, and controls the operation of all four components.

[0007] In the above-mentioned integrated hot and cold water purifier, a normal temperature water pipe is connected between the solenoid valve assembly and the cold water connector, and both the normal temperature water pipe and the cold water outlet pipe are connected to the cold water connector.

[0008] In the above-mentioned integrated hot and cold water purifier, a temperature sensor three is installed on the room temperature water pipe. The temperature sensor three is used to detect the water temperature in the room temperature water pipe, and the temperature sensor three is electrically connected to the controller.

[0009] In the above-mentioned integrated hot and cold water purifier, a bypass pipe is provided at the end of the hot water outlet pipe, and the ends of the cold water outlet pipe and the room temperature water pipe are connected to a bypass pipe. Both the bypass pipe and the bypass pipe are connected to the drain valve.

[0010] In the aforementioned integrated hot and cold water purifier, the cold water outlet pipe is connected to the top of the cold water tank, and the hot water outlet pipe is connected to the top of the hot water tank.

[0011] In the aforementioned integrated hot and cold water purifier, the refrigeration component includes a copper pipe, a compressor, a heat exchanger, and a temperature sensor. The copper pipe is wound around the outside of the cold water tank. The compressor and heat exchanger are spaced apart on the frame. One end of the copper pipe is connected to the heat exchanger, and the other end is connected to the compressor. The compressor and heat exchanger are connected by a pipe. The compressor contains refrigerant and can circulate the refrigerant sequentially to the heat exchanger and the copper pipe. The temperature sensor is located on the cold water tank and is used to detect the water temperature inside the cold water tank. The temperature sensor, compressor, and heat exchanger are all electrically connected to the controller.

[0012] In the above-mentioned integrated hot and cold water purifier, the heating component includes a heating plate and a second temperature sensor. The heating plate is disposed inside the hot water tank, and the second temperature sensor is disposed on the hot water tank. Both the second temperature sensor and the heating plate are electrically connected to the controller.

[0013] In the aforementioned integrated hot and cold water purifier, the controller is controlled by a control board.

[0014] In the aforementioned integrated hot and cold water purifier, both the cold water tank and the hot water tank are equipped with heat insulation covers.

[0015] In the aforementioned integrated hot and cold water purifier, a drain pipe is installed at the bottom of the cold water tank, and a drain pipe is installed at the bottom of the hot water tank.

[0016] In summary, the beneficial effects of this utility model compared to the prior art are as follows: This water purifier is used in conjunction with a water purifier. The filtered water is connected to the inlet pipe, supplying water to the solenoid valve assembly. The controller then controls the solenoid valve assembly to distribute water to the cold water tank, hot water tank, or ambient temperature water pipe. At this time, the drain valve is closed. When the solenoid valve assembly supplies water to the cold water tank through supply pipe one, the purified water first fills the cold water tank, then flows out through the cold water outlet pipe at the top of the cold water tank via the cold water connector. During this process, the cooling component cools the water in the cold water tank, allowing cold water to be discharged directly from the cold water connector. When the solenoid valve assembly supplies water to the hot water tank through supply pipe two, the purified water fills the hot water tank. The water then flows out through the hot water outlet pipe at the top of the hot water tank via the hot water connector. The heating component heats the water in the hot water tank, so whenever water is supplied to the hot water tank, the heated water flows out through the hot water outlet pipe. When the solenoid valve assembly supplies water to the ambient temperature water pipe, the purified water flows directly from the ambient temperature water pipe and the cold water connector; this portion of the water is at ambient temperature. The cold water connector and hot water connector are connected to the faucet. The same faucet can directly discharge cold water, hot water, and room temperature water. Users do not need to manually heat or cool the purified water. The operation is simple and can meet the user's water needs, improve the user experience, and enhance the convenience of using the under-sink water purifier.

[0017] Moreover, when the water supply to the inlet pipe is stopped, the drain valve is in the normally open state. The water vapor generated during the heating process of the hot water tank and the residual water in the cold water connector can be directly discharged from the drain valve, thereby effectively avoiding the problem of water and temperature cross-flow at different temperatures at the faucet, and ensuring that the water temperature discharged from the faucet is more accurate each time.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] A type of under-sink water purifier that combines hot and cold water, such as Figures 1-9 As shown, the system includes a frame 100, a cold water tank 200, a hot water tank 300, and a controller 400. A solenoid valve assembly 500 is installed inside the frame 100. A housing 110 is mounted on the frame 100, and pipe connectors 600 are spaced apart on the housing 110. Each pipe connector 600 includes an inlet connector 610, a cold water connector 620, a hot water connector 630, and a drain connector 640. An inlet pipe 611 connects the inlet connector 610 to the solenoid valve assembly 500. The solenoid valve assembly 500 supplies water to the cold water tank 200 through a first water supply pipe 510 and to the hot water tank 300 through a second water supply pipe 520. A cold water outlet is provided on the cold water connector 620, which connects to the cold water tank 200. Pipe 621 and hot water connector 630 are provided with a hot water outlet pipe 631 that connects to the hot water tank 300; the height of drain connector 640 is lower than the other connectors, and drain connector 640 is provided with a drain valve 641. Both cold water outlet pipe 621 and hot water outlet pipe 631 can be connected to drain valve 641; a refrigeration component 210 is provided outside the cold water tank 200, and a heating component 310 is provided on the hot water tank 300; the controller 400 is electrically connected to the refrigeration component 210, the heating component 310, the solenoid valve group 500, and the drain valve 641, and the controller 400 controls the operation of the refrigeration component 210, the heating component 310, the solenoid valve group 500, and the drain valve 641.

[0022] like Figure 1 , Figure 3 As shown, the rack 100 is provided with an assembly box 120 for mounting the controller 400. The controller 400 is a conventional microcontroller. The controller 400 is controlled by a control board 410. The control board 410 includes a control panel mounted on the rack 100 or a remote control mounted on the faucet. The control panel is electrically connected to the controller 400, and the remote control is electrically connected to or wirelessly connected to the controller 400. The controller 400 is used to receive control signals from the control board 410 and execute the signals.

[0023] like Figures 4-6 As shown, the solenoid valve assembly 500 is a one-in-three-out solenoid valve. The solenoid valve assembly 500 is connected to the cold water connector 620 by a normal temperature water pipe 530. Both the normal temperature water pipe 530 and the cold water outlet pipe 621 are connected to the cold water connector 620. That is, normal temperature water and cold water share a single connector for water flow.

[0024] Furthermore, a temperature sensor 531 is installed on the ambient temperature water pipe 530. The temperature sensor 531 is used to detect the water temperature inside the ambient temperature water pipe 530, and the temperature sensor 531 is electrically connected to the controller 400.

[0025] like Figures 4-7 As shown, a bypass pipe 1 6311 is provided at the end of the hot water outlet pipe 631, and a bypass pipe 2 6211 is connected to the ends of the cold water outlet pipe 621 and the ambient temperature water pipe 530. Both bypass pipe 1 6311 and bypass pipe 2 6211 are connected to the drain valve 641. The drain valve 641 is a single-inlet, single-outlet solenoid valve, and its opening and closing are controlled by the controller 400. When the drain valve 641 is open, bypass pipe 1 6311 and bypass pipe 2 6211 are connected to the drain connector 640. When the drain valve 641 is closed, it isolates bypass pipe 1 6311 and bypass pipe 2 6211 from the drain connector 640. A drain pipe is connected to the outside of the drain connector 640, and the other part of the drain pipe can be inserted into the drain pipe. Water vapor or water flow in the drain connector 640 can be directly discharged into the drain pipe through the drain pipe.

[0026] Both the cold water tank 200 and the hot water tank 300 are used for water storage. Both the cold water tank 200 and the hot water tank 300 are equipped with heat insulation covers 220. The two heat insulation covers 220 are used to maintain the water temperature inside the cold water tank 200 and the hot water tank 300 respectively, and at the same time, they can also prevent temperature interference between the cold water tank 200 and the hot water tank 300.

[0027] The cold water outlet pipe 621 is connected to the top of the cold water tank 200, and the hot water outlet pipe 631 is connected to the top of the hot water tank 300. Furthermore, water supply pipe one 510 is connected to the bottom of the cold water tank 200, and water supply pipe two 520 is connected to the bottom of the hot water tank 300. This ensures that water can only enter from the bottom of the cold water tank 200 and flow out from the top, and similarly, water can only enter from the bottom of the hot water tank 300 and flow out from the top.

[0028] like Figure 3 , Figure 7 As shown, the refrigeration assembly 210 includes a copper pipe 211, a compressor 212, a heat exchanger 213, and a temperature sensor 214. The copper pipe 211 is wound around the cold water tank 200. The compressor 212 and the heat exchanger 213 are spaced apart on the frame 100. One end of the copper pipe 211 is connected to the heat exchanger 213, and the other end of the copper pipe 211 is connected to the compressor 212. The compressor 212 and the heat exchanger 213 are connected by a pipe, so that the copper pipe 211, the compressor 212, and the heat exchanger 213 form a closed loop. The compressor 212 contains refrigerant. When the compressor 212 is working, it sequentially delivers the refrigerant to the heat exchanger 213 and the copper pipe 211, and finally the refrigerant flows back into the compressor 212. In other words, the refrigerant can circulate sequentially within the compressor 212, heat exchanger 213, and copper pipe 211. The heat exchanger 213 is used to cool the refrigerant, while the copper pipe 211 cools the cold water tank 200 and the water inside. A temperature sensor 214 is installed on the cold water tank 200 and is used to detect the water temperature inside the tank. The temperature sensor 214, compressor 212, and heat exchanger 213 are all electrically connected to the controller 400.

[0029] like Figure 7 , Figure 8 As shown, the heating component 310 includes a heating plate 311 and a second temperature sensor 312. The heating plate 311 is disposed at the bottom of the hot water tank 300, and the second temperature sensor 312 is disposed on the hot water tank 300. Both the second temperature sensor 312 and the heating plate 311 are electrically connected to the controller 400. In some embodiments, a baffle plate 3111 is fixed on the heating plate 311. The baffle plate 3111 is located at the end of the second water supply pipe 520. Water can only enter the hot water tank 300 between the heating plate 311 and the baffle plate 3111. The baffle plate 3111 is used to prevent the water flow from the second water supply pipe 520 from directly entering the upper part of the hot water tank 300, thus ensuring the heating effect of the water flow in the hot water tank 300.

[0030] like Figure 8 , Figure 9As shown, in at least one embodiment, a drain pipe 230 is provided at the bottom of the cold water tank 200, and a drain pipe 320 is provided at the bottom of the hot water tank 300. The drain pipes 230 and 320 extend downward through the frame 100, and both drain pipes 230 and 320 are sealed by plugs 231. By removing the plugs 231, the water in the cold water tank 200 can be completely drained through the drain pipe 230, and the water in the hot water tank 300 can be completely drained through the drain pipe 320, so as to facilitate the inspection or maintenance of this water purifier.

[0031] The working principle of this utility model is as follows: This water purifier is placed inside a cabinet and used in conjunction with a water purifier. The purified water produced by the water purifier is connected to the inlet connector 610 through a pipe. The purified water then supplies water to the solenoid valve assembly 500 through the inlet pipe 611. The controller 400 controls the solenoid valve assembly 500 to distribute water flow to the cold water tank 200, the hot water tank 300, or the room temperature water pipe 530. At this time, the drain valve 641 is closed.

[0032] When the solenoid valve assembly 500 supplies water to the cold water tank 200 only through the water supply pipe 510, the inlet pipe 611 is only connected to the water supply pipe 510. The purified water will first fill the cold water tank 200, and then the cold water tank 200 will remain full. The water flowing into the cold water tank 200 will directly squeeze the water in the cold water tank 200 from the cold water outlet pipe 621 into the cold water connector 620 to realize the discharge of cold water. The compressor 212 drives the refrigerant to flow back into the compressor 212 from the heat exchanger 213 and the copper pipe 211. The heat exchanger 213 is used to cool the refrigerant, and the refrigerant in the copper pipe 211 cools the water in the cold water tank 200, thus realizing the cooling of the refrigeration component 210. When the solenoid valve assembly 500 supplies water to the hot water tank 300 only through the second water supply pipe 520, the inlet pipe 611 is only connected to the second water supply pipe 520. The purified water will first fill the hot water tank 300, and then the hot water tank 300 will remain full, continuously supplying water to the hot water tank 300. The water flowing into the hot water tank 300 will then be directly squeezed into the hot water connector 630 from the hot water outlet pipe 631, realizing the discharge of hot water. After the heating plate 311 is powered on, it can heat the water in the hot water tank 300, realizing the heating component 310 heating the water flow in the hot water tank 300. When the solenoid valve assembly 500 supplies water only to the ambient temperature water pipe 530, the inlet pipe 611 is only connected to the ambient temperature water pipe 530, and the clean water flows directly out from the ambient temperature water pipe 530 and the cold water connector 620. This part of the water flow is ambient temperature water flow.

[0033] Since both the cold water tank 200 and the hot water tank 300 are full, only by continuously supplying clean water to the cold water tank 200 can the water flow continuously out of the cold water outlet pipe 621. The same applies to the hot water tank 300. The water flowing from the ambient temperature water pipe 530 into the cold water connector 620 cannot flow back into the cold water tank 200. Therefore, there is no need to use a one-way valve in the cold water outlet pipe 621 to ensure the normal flow direction of ambient temperature water and cold water, thus saving production costs.

[0034] The cold water connector 620 and the hot water connector 630 are connected to the faucet through the same pipe. The same faucet can directly discharge cold water, hot water, and room temperature water. When the faucet is closed, the water supply from the inlet pipe 611 stops. At this time, the drain valve 641 opens, and the drain connector 640 is connected to the drain pipe. Since the height of the faucet is higher than that of each pipe connector 600, and the height of the drain connector 640 is lower, the residual water in the faucet, cold water connector 620, and hot water connector 630 is discharged from the drain connector 640 through the bypass pipe 6311 or the bypass pipe 6211 by its own weight and water pressure. This realizes the discharge of residual water in the faucet and effectively avoids the problem of water and temperature cross-flow in the faucet.

[0035] In addition, the steam generated by heating in the hot water tank 300 can be directly discharged from the bypass pipe 6311 and the drain connector 640, avoiding damage to the hot water outlet pipe 631 or the faucet by the steam.

[0036] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
