[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] Figure 1 This is a schematic diagram illustrating the working principle of an energy-saving hot and warm water dispenser that utilizes a heat transfer medium for heat preservation, as provided in this embodiment of the utility model. Figure 1 As shown, this energy-saving hot and warm water machine that utilizes a heat transfer medium for heat preservation includes: the hot and warm water machine body and the heat preservation system.

[0018] The heat preservation system is installed on the main body of the hot and warm water dispenser. It should be noted that the main body of the hot and warm water dispenser has the structure of existing hot and warm water dispensers, while the heat preservation system is an improved structure of this application. Therefore, this application focuses on describing the structure of the heat preservation system.

[0019] The insulation system includes: a warm water tank 25, a hot water tank 13, a heat medium circulation loop, and a control module.

[0020] The heat medium circulation loop is a closed loop.

[0021] The heat transfer medium circulation loop includes a first heat exchange section 19, a second heat exchange section 27, a phase-changeable heat transfer medium 26, a first medium connecting pipe 20, and a second medium connecting pipe 22. The first heat exchange section 19 is located inside the boiling water tank 13, the second heat exchange section 27 is located inside the warm water tank 25, and the phase-changeable heat transfer medium 26 is located within the heat transfer medium circulation loop and has a boiling point lower than that of water.

[0022] In a specific example, the first heat exchange section 19 can be a medium holding pipe, which can be welded inside the hot water tank 13 to hold the phase change heat transfer medium 26. The phase change heat transfer medium 26 can be edible alcohol. The second heat exchange section 27 can be a condenser tube.

[0023] Since the boiling point of alcohol is around 78.6℃, which is lower than that of water, the alcohol in the first heat exchange section 19 absorbs heat from the boiling water tank 13 and vaporizes. Then, it passes through the first medium connecting pipe 20 and the second medium connecting pipe 22 in sequence and enters the second heat exchange section 27. The vaporized alcohol is cooled and liquefied in the second heat exchange section 27, and the released heat is used to heat the water in the warm water tank 25. The liquid alcohol will return to the first heat exchange section 19 along the same path. This cycle continues, causing the water temperature in the warm water tank 25 to rise continuously.

[0024] The control module is connected to the heat medium circulation loop and configured to: acquire the water temperature of the warm water tank 25; when the water temperature of the warm water tank 25 is determined to be lower than the preset lower limit of the heat preservation temperature, control the heat medium circulation loop to be turned on so as to use the phase change heat medium 26 to carry the heat from the boiling water tank 13 into the warm water tank 25 to heat the water in the warm water tank 25; when the water temperature of the warm water tank 25 is determined to reach the preset upper limit of the heat preservation temperature, control the heat medium circulation loop to be turned off so as to stop heating the warm water tank 25.

[0025] In a specific example, the control module may include: a first temperature sensor 24, a controller ( Figure 1 (not shown in the image) and controllable valve 21.

[0026] The first temperature sensor 24 and the controllable valve 21 are respectively connected to the controller for communication.

[0027] The controllable valve 21 is installed in the heat medium circulation loop, specifically between the first medium connecting pipe 20 and the second medium connecting pipe 22. The first temperature sensor 24 can be installed on the outer shell of the warm water tank 25, with its probe inserted into the interior of the warm water tank 25 to detect the water temperature data of the warm water tank 25. The controllable valve 21 can be an electric valve or a solenoid valve.

[0028] In actual operation, after the first temperature sensor 24 detects the water temperature data of the warm water tank 25, it sends the water temperature data to the controller. The controller controls the opening or closing of the controllable valve 21 according to the water temperature data, the preset lower limit of the insulation temperature and the preset upper limit of the insulation temperature, so as to realize the conduction or disconnection of the heat medium circulation loop.

[0029] In this embodiment of the invention, a pressure relief valve 37 is also provided on the heat medium circulation loop. The second heat exchange unit 27 can be disposed between the pressure relief valve 37 and the controllable valve 21. The pressure relief valve 37 is used to release pressure when the gas pressure in the heat medium circulation loop exceeds a preset gas pressure threshold, so as to protect the heat medium circulation loop.

[0030] In this embodiment of the utility model, an inner coil 12 is provided inside the hot water tank 13.

[0031] External water flows into the warm water tank 25 through the inner coil 12. The inner coil 12 is used to preheat the water flowing into the warm water tank 25 using the heat from the boiling water tank 13.

[0032] The main body of the hot and warm water dispenser includes: a control device ( Figure 1 (Not shown), First inlet pipe 1, Filter 2, First tee 3, Pressure tank 4, Second inlet pipe 5, Heat exchanger 6, Temperature control valve 7, Third inlet pipe 8, Second tee 9, Angle valve 10, Inlet solenoid valve 11, Outlet pipe 14, Outlet solenoid valve 15, First outlet nozzle 16, Fourth inlet pipe 17, Heating element 18, Inlet float 23, Warm water outlet pipe 28, Warm water outlet solenoid valve 29, Second outlet nozzle 30, Fifth inlet pipe 31, Sixth inlet pipe 32, Seventh inlet pipe 33, High water level probe 34, Low water level probe 35, and Second temperature sensor 36.

[0033] The inlet float 23 is located inside the warm water tank 25.

[0034] Heating element 18, high water level probe 34, low water level probe 35, and second temperature sensor 36 are installed inside the hot water tank 13. Angle valve 10, water solenoid valve 11, heating element 18, high water level probe 34, low water level probe 35, and second temperature sensor 36 are all communicatively connected to the control device. Angle valve 10 is an electric angle valve.

[0035] The hot water tank 13, the inlet solenoid valve 11, the second three-way valve 9, the heating element 18, the heat exchanger 6, the second inlet pipe 5, the first three-way valve 3, the filter 2, the pressure tank 4 and the first inlet pipe 1 are connected in sequence.

[0036] The upper end of the inner coil 12 is connected to the first end of the fifth water inlet pipe 31 through the hot water tank 13, and the second end of the fifth water inlet pipe 31, the angle valve 10, and the second tee 9 are connected in sequence.

[0037] The lower port of the inner coil 12, the sixth water inlet pipe 32, the seventh water inlet pipe 33, the temperature control valve 7, and the fourth water inlet pipe 17 are connected in sequence.

[0038] The bottom of the hot water tank 13 is connected to the first end of the water outlet pipe 14, and the second end of the water outlet pipe 14, the water outlet solenoid valve 15, and the first water outlet nozzle 16 are connected in sequence.

[0039] The warm water tank 25 is connected to the first end of the warm water outlet pipe 28, and the second end of the warm water outlet pipe 28, the warm water outlet solenoid valve 29, and the second water outlet nozzle 30 are connected in sequence.

[0040] Filter 2 can be an RO (Reverse Osmosis) filter. The RO filter can have five sets of filters, with the filter elements arranged in the following order: PP cotton, compressed activated carbon, post-activated carbon, RO membrane, and post-activated carbon (on top). The pressure tank 4 can have a capacity of 11 gallons.

[0041] In actual operation, external water first flows into the first inlet pipe 1, is filtered by the filter 2, and then enters the pressure tank 4 through the first three-way valve 3. After the pressure tank 4 is full, the water flows into the hot water tank 13 through the second inlet pipe 5, the outer pipe of the heat exchanger 6, the third inlet pipe 8, and a branch of the second three-way valve 9. When the control device determines that the water level in the hot water tank 13 is lower than the water level corresponding to the high water level probe 34 based on the water level detection data sent by the high water level probe 34, it controls the water solenoid valve 11 to be in the open state, so that the water flowing into the third inlet pipe 8 flows into the hot water tank 13. As the water level rises, when the control device determines that the water level in the hot water tank 13 reaches or exceeds the water level corresponding to the high water level probe 34 based on the water level detection data sent by the high water level probe 34, it controls the water solenoid valve 11 to be in the closed state, so as to stop adding water to the hot water tank 13. Secondly, when the control device determines that the water level in the hot water tank 13 is at or below the water level corresponding to the low water level probe 35 based on the water level detection data sent by the low water level probe 35, it controls the heating element 18 to start heating until it determines that the water level in the hot water tank 13 reaches or exceeds the water level corresponding to the high water level probe 34. Furthermore, when it determines that the water temperature in the hot water tank 13 reaches 100°C based on the water temperature data sent by the second temperature sensor 36, it controls the heating element 18 to stop heating.

[0042] After the heating element 18 stops heating, the control device opens the angle valve 10, allowing water flowing into the third inlet pipe 8 to pass through the inner coil 12, the sixth inlet pipe 32, the temperature regulating valve 7, the thin tube of the heat exchanger 6, and the fourth inlet pipe 17 into the warm water tank 25. Since the inner coil 12 is located inside the boiling water tank, the heat from the boiling water tank 13 is transferred to the inner coil 12, thus heating the water inside the inner coil 12 and preheating the water flowing into the warm water tank 25. The float ball 23 acts as a stop valve when the warm water tank 25 is full. The warm water in the warm water tank 25 flows through the warm water outlet pipe 28 and the warm water solenoid valve 29 before exiting from the second outlet spout 30.

[0043] In a specific example Figure 2 This is a schematic diagram of the external structure of an energy-saving hot and warm water dispenser that utilizes a heat transfer medium for heat preservation, as provided in an embodiment of this utility model. Figure 2 As shown, the shell 203 of the energy-saving hot and warm water dispenser that uses a heat transfer medium for heat preservation is equipped with a temperature display screen 201, a hot water outlet control and indication structure 202, a warm water outlet control and indication structure 205, a first water outlet 16, a second water outlet 30, and a support structure 204.

[0044] The temperature display screen 201 is communicatively connected to the control device and is used to display data sent by the control device, such as the water temperature in the hot water tank 13 and the heating status of the hot water tank 13.

[0045] The warm water outlet control and indication structure 205 consists of a warm water indicator light and a warm water control button. When the warm water control button is pressed, warm water flows out of the second water outlet 30, and the warm water indicator light illuminates at the same time. When the warm water control button returns to its normal state due to the absence of external force, the second water outlet 30 stops discharging water, and the warm water indicator light goes out.

[0046] The hot water dispensing control and indication structure 202 consists of a hot water indicator light and a hot water control button. When the hot water control button is pressed, hot water flows out of the first water outlet 16, and the hot water indicator light illuminates at the same time. When the hot water control button returns to its normal state due to the absence of external force, the first water outlet 16 stops dispensing water, and the hot water indicator light goes out.
