Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to an instant hot water faucet. Background Technology

[0002] The direct drinking water supply equipment is connected to the purification equipment. The water purified by the purification equipment is then output through the direct drinking water supply equipment, and this water is generally safe to drink directly. In the current technology, direct drinking water supply equipment is usually a highly integrated countertop faucet.

[0003] To further enhance convenience, related technologies incorporate instant heating modules into faucets. These modules rapidly heat the water to a specific temperature. The instant heating module is typically located on the faucet's upright post and generally includes an outer casing. Inside the casing, a heating channel is formed, and a heating element is placed within the channel. Water passes through the heating element to be heated.

[0004] For example, CN219547925U discloses a temperature-controlled sensor faucet, which includes a faucet body with a built-in water-passing bend, a temperature-regulating device, a sensing device, and a solenoid valve. The faucet body has a bend structure, and the faucet body is equipped with an adapter. The temperature-regulating device and the adapter are detachably connected.

[0005] In the aforementioned temperature-controlled sensor faucet technology, when using hot water, room temperature water is heated to become hot water, and the hot water contains steam. If it is released directly for use, the water flow will be affected by the steam, which will affect the smoothness of the water flow. Utility Model Content

[0006] The purpose of this utility model is to provide an instant hot water faucet to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An instant hot water faucet includes:

[0009] A column housing, with a cantilever housing mounted on top of the column housing;

[0010] A central water pipe, which is located inside the column housing and is fitted with an instant heating module;

[0011] A heating water pipe is attached to the periphery of the instant heating module and distributed in a serpentine pattern along the length of the instant heating module.

[0012] A knob, which is rotatably mounted on one end of the cantilever housing and has a built-in encoder;

[0013] A temperature sensor, located at the central water pipe and the heating water pipe, is used to detect the inlet and outlet water temperatures.

[0014] The display module is located on the cantilever housing and includes a control board, a power board, and a display panel.

[0015] The power board is used to supply power to the control board, display board, and heating water pipes;

[0016] The encoder's rotation controls the heating of the hot water pipe via the control board to regulate the temperature and flow rate of the outlet water. The control board displays the water temperature and flow rate via the display panel.

[0017] The bottom end of the heating water pipe is connected to the bottom end of the central water pipe and connected to the inlet pipe. The top end of the heating water pipe is connected to the top end of the central water pipe through a water pipe with a solenoid valve to the water vapor separation unit, which is installed at the lower end of the cantilever housing.

[0018] Furthermore, the water vapor separation unit includes a box body and a lid covering the box body. The box body has a first cavity and a second cavity that are independent of each other. The first cavity forms a serpentine channel through a baffle, and the end of the first cavity has a first water outlet pipe. The end of the second cavity has a second water pipe. There is a hot air exhaust port at the connection between the first cavity and the second cavity, and the hot air exhaust port is connected to the second water pipe.

[0019] Furthermore, the second water pipe is fitted onto the first water outlet pipe, the bottom of the second water pipe has a filter plate, and a support pipe is fitted inside the second water pipe. A conical filter screen is fitted onto the support pipe. The box body has a first water inlet and a second water inlet. The water pipe includes a first water pipe and a second water pipe. The first water pipe is connected to the first water inlet and the heating water pipe, respectively. The second water pipe is connected to the second water inlet and the central water pipe, respectively.

[0020] Furthermore, the temperature sensors are respectively installed at the bottom of the central water pipe and at the top of the heating water pipe.

[0021] Furthermore, a temperature control switch is attached to the instant heating module.

[0022] Furthermore, the display module includes a PC display screen and a digital display screen, wherein the PC display screen is mounted on the upper surface of the cantilever housing, and the digital display screen is mounted on the upper surface of the knob.

[0023] Furthermore, the bottom end of the column housing has a threaded tube with a washer and a nut.

[0024] Furthermore, the control board, power board, and display board are all equipped with MCU microcontrollers, and the MCU microcontroller on the control board also integrates a buzzer.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention heats room-temperature water entering the faucet using an instant heating module, avoiding the health risks associated with repeatedly boiled water. It also simplifies the water dispenser's structure by eliminating the heating tank and the instant heating module. This improves the user experience by reducing residual water between the faucet and the dispenser, enhancing the overall experience; multiple temperature options allow for immediate use of water for brewing tea, coffee, making formula, and preparing dry goods; hot water is available instantly without waiting; and the faucet design is minimalist, unlike conventional countertop dispensers that occupy limited countertop space.

[0027] In this invention, room temperature water enters the heating water pipe and the central water pipe from the bottom of the inlet pipe through the inlet pipe. Because the water is heated by the instant heating module, the water in the heating water pipe can be heated to the required temperature and used as hot water, while the central water pipe is used as room temperature water, thus enabling the faucet to have both hot and cold water functions.

[0028] In this invention, hot water and room temperature water enter the water vapor separator housing through two water channels, a first inlet and a second inlet, respectively. When the hot water enters the housing through the first inlet, it is buffered by multiple baffles, causing the hot vapor contained within the hot water to separate from the hot water. The vapor rises to the top and exits through the hot vapor vent, while the hot water flows out through the first outlet pipe. Finally, it overflows through the holes in the filter plate via the gap between the filter screen and the first outlet pipe, exiting through the water inlet. Because the hot water and hot vapor are separated, the water flow is smoother and unaffected by the hot vapor, ensuring a smooth flow of hot water from the faucet.

[0029] This invention utilizes the circulating water flow in the heating pipe to recover heat from the aluminum profile, thus controlling the surface temperature of the faucet product below 45℃. Two or more temperature control switches are used for multi-point temperature control protection. Attached Figure Description

[0046] Please see Figures 1 to 12 This utility model provides a technical solution:

[0047] An instant hot water faucet, characterized in that it comprises:

[0048] A column housing 1, with a cantilever housing 2 mounted on top of the column housing 1;

[0049] The central water pipe 15 is located inside the column housing 1 and is fitted with an instant heating module 3;

[0050] Heating water pipe 5, which is attached to the periphery of the instant heating module 3 and distributed in a serpentine pattern along the length of the instant heating module 3;

[0051] Knob 9, which is rotatably mounted on one end of the cantilever housing 2, and has a built-in encoder;

[0052] Temperature sensor 7, located at the central water pipe 15 and the heating water pipe 5, is used to detect the inlet and outlet water temperatures.

[0053] The display module is located on the cantilever housing 2 and includes a control board, a power board and a display panel;

[0054] The power board is used to supply power to the control board, the display board, and the heating water pipe 5;

[0055] The encoder's rotation controls the heating of the hot water pipe 5 via the control board to regulate the temperature and flow rate of the outlet water. The control board displays the water temperature and flow rate via the display panel.

[0056] The bottom end of the heating water pipe 5 is connected to the bottom end of the central water pipe 15 and connected to the inlet pipe 6. The top end of the heating water pipe 5 and the top end of the central water pipe 15 are connected to the water vapor separation unit 12 through a water pipe with a solenoid valve. The water vapor separation unit 12 is installed at the lower end of the cantilever housing 2.

[0057] Specifically, the water vapor separation unit 12 includes a box body 16 and a box cover 17 covering the box body 16. The box body 16 has a first cavity 21 and a second cavity 22 that are independent of each other. The first cavity 21 forms a serpentine channel through a baffle 20, and the end of the first cavity 21 has a first water outlet pipe 24. The end of the second cavity 22 has a second water pipe 27. There is a hot air exhaust port 23 at the connection between the first cavity 21 and the second cavity 22, and the hot air exhaust port 23 is connected to the second water pipe 27.

[0058] Specifically, the second water pipe 27 is fitted onto the first water outlet pipe 24. The bottom of the second water pipe 27 has a filter plate 28, and a support pipe 26 is fitted inside the second water pipe 27. A conical filter screen cylinder 25 is fitted onto the support pipe 26. The box body 16 has a first water inlet 18 and a second water inlet 19. The water pipe includes a first water pipe 13 and a second water pipe 14. The first water pipe 13 is connected to the first water inlet 18 and the heating water pipe 5, respectively. The second water pipe 14 is connected to the second water inlet 19 and the central water pipe 15, respectively.

[0059] Specifically, the temperature sensors 7 are respectively installed at the bottom of the central water pipe 15 and at the top of the heating water pipe 5.

[0060] Specifically, a temperature control switch 8 is attached to the instant heating module 3.

[0061] Specifically, the display module includes a PC display screen 10 and a digital display screen 11, wherein the PC display screen 10 is mounted on the upper surface of the cantilever housing 2, and the digital display screen 11 is mounted on the upper surface of the knob 9.

[0062] Specifically, the bottom end of the column housing 1 has a threaded tube 29 with a washer and a nut.

[0063] Specifically, such as Figure 1 As shown, the control board, power board, and display board all have MCU microcontrollers, and the MCU microcontroller on the control board also integrates a buzzer.

[0064] As a specific embodiment, the MCU microcontroller and its peripheral circuits on the power board are as follows: Figure 2As shown, the MCU model can be IC_BF7812AM28.

[0065] As a specific embodiment, the MCU microcontroller and its peripheral circuits on the power board are as follows: Figure 3 As shown, the MCU model can be IC_BF7812AM28.

[0066] As a specific embodiment, the display board's MCU microcontroller and its peripheral circuits are as follows: Figure 4 As shown, the MCU microcontroller model can be IC_BF7612CM20.

[0067] The faucet of this utility model is connected to the water outlet pipe of the water purifier via a threaded pipe 29. For example... Figure 5 As shown, the room temperature water in the water purifier's outlet pipe is pumped into the inlet pipe 6 through a pressure reducing valve, a flow meter, and a diaphragm pump. Then, it is heated into hot water by the instant heating module 3 and flows out through the water vapor separation unit 12 for use.

[0068] In this invention, room temperature water enters the heating water pipe 5 and the central water pipe 15 from the bottom ends of the inlet pipe 6. Because the instant heating module 3 is used for heating, the water in the heating water pipe 5 can be heated to the required temperature for use as hot water, while the central water pipe 15 is used for room temperature water, thus enabling the faucet to function as both hot and cold water. The heating water pipe 5 is closely attached to the perimeter of the instant heating module 3, arranged in a serpentine (or "S") shape along the length of the module 3. This not only maximizes the length of the heating water pipe 5 but also increases the length of the water flow within it, thereby extending the heating time and ensuring the water reaches the required temperature. Furthermore, the serpentine arrangement of the heating water pipe 5, close to the instant heating module 3, not only ensures heating efficiency but also saves space in the column housing 1, making the faucet structure more compact and easier to control in size. This effectively solves the problem of a large diameter column housing 1 in related technologies.

[0069] In this invention, the heating water pipe 5 is secured at the insertion position 4, and a thick-film heating element is used. The instant heating module 3 uses an aluminum profile as the heating component. The specific structure of the thick-film heating element is: a tube body with a stainless steel substrate, and an insulating layer, a conductive layer, a resistive layer, and a covering layer that are wrapped around the stainless steel substrate from the inside out. The heating water pipe 5 collects the entire heat from the aluminum profile, resulting in more complete heat collection and a significant effect.

[0070] In this invention, the top end of the heating water pipe 5 and the top end of the central water pipe 15 are connected to the water vapor separation unit 12 via a water pipe equipped with a solenoid valve. The water vapor separation unit 12 is installed at the lower end of the cantilever housing 2. When hot water or room temperature water is needed, the solenoid valve (not shown in the figure) can be controlled by the control board to open and close the corresponding water pipe, thereby realizing the opening and closing of the water circuit for room temperature water and hot water. For example, when hot water is needed, the heating water pipe 5, the first water pipe 13, and the first inlet 18 can be connected. When room temperature water is needed, the second water pipe 14, the second inlet 19, and the central water pipe 15 can be connected.

[0071] This utility model, such as Figures 9 to 12 As shown, hot water and room temperature water enter the water vapor separator box 16 through the first inlet 18 and the second inlet 19, respectively. When hot water enters the box 16 through the first inlet 18, it is buffered by multiple baffles 20 in the serpentine channel. The hot gas contained in the hot water separates from the hot water. The gas floats on top and is discharged from the hot gas exhaust port 23, while the hot water is discharged from the bottom through the first outlet pipe 24. Then, it overflows from the faucet through the gap a between the filter screen cylinder 25 and the first outlet pipe 24, and finally overflows from the faucet through the holes of the filter plate 28. After the hot water and hot gas separate, the water flow becomes smoother without being affected by the hot gas, thus ensuring the smooth flow of hot water from the faucet.

[0072] This invention heats room-temperature water entering the faucet using an instant heating module 3, avoiding the health risks associated with repeatedly boiled water. It also simplifies the water purifier's structure by eliminating the heating tank and the instant heating module. This improves the user experience by reducing residual water between the faucet and the purifier, enhancing the overall experience; multiple temperature options allow for direct consumption of tea, coffee, formula, and dry goods preparation; hot water is available instantly upon startup, eliminating waiting time; and the faucet design is minimalist, unlike conventional countertop water purifiers that occupy limited countertop space.

[0073] In this invention, the circulating water from the heating pipe 5 recovers heat from the aluminum profile, keeping the surface temperature of the faucet below 45°C. Two or more temperature control switches 8 are used for multi-point temperature control protection.
