Description

Technical Field

[0001] This invention relates to the field of air source heat pump water tank technology, and in particular to an air source heat pump water tank with automatic water volume control. Background Technology

[0002] The working principle of an air source heat pump water heater is to absorb low-temperature heat from the air, vaporize it through a refrigerant medium, compress it through a compressor to increase its pressure and temperature, and then transfer it to the water through a heat exchanger. The high-temperature heat energy after compression is used to heat the water. When the air source heat pump unit is working, outdoor air enters the unit's internal cavity through the air inlet under the suction of the fan, flows through the heat exchanger, and the energy in the air is absorbed by the heat exchanger and transferred to the insulated water tank. This avoids placing electrical appliances in the insulated water tank, thus preventing the risk of electric leakage.

[0003] Since the volume of the insulated water tank is fixed, each heating requires heating the entire volume of water. However, in actual use, due to differences in the number of users, heating the entire volume when water consumption is low will result in waste of hot water. Therefore, patent CN116951765A proposes an energy-saving air-source heat pump water tank. The key technical features include a cylindrical tank with an inlet pipe and a primary outlet pipe. A condenser pipe is installed in the upper half of the tank, and both the outlet and inlet pipes are located in the upper half. A heat insulation plate is installed in the middle of the tank, with drainage holes. The heat insulation plate is rotatably connected to a sealing plate, which is connected to a rotating shaft. The upper end of the shaft extends beyond the upper end of the tank. A motor is installed at the upper end of the tank to drive the rotating shaft to open and close the drainage holes. The tank is divided into compartments, allowing heating of water in individual compartments. This reduces energy loss and achieves energy conservation for users with low-flow hot water needs.

[0004] However, its water volume control cannot be flexibly adjusted, the water volume usage is quite limited, and the water outlet pipe position is fixed. In order to adapt to different water levels, corresponding water outlet pipes need to be installed, which makes the adjustment during use quite complicated. Therefore, this invention proposes an air source water tank that can automatically control the water volume. Summary of the Invention

[0020] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Example

[0021] Please see Figures 1-6 This invention provides a technical solution: an air-source heat pump water tank with automatic water volume control, comprising an outer cylinder 1, an inner cylinder 2, an outdoor unit 5, an exhaust pipe 14, an adjustment component 21, and a positioning component 22. The outdoor unit 5 is located on one side of the outer cylinder 1. The inner cylinder 2 is welded to the inside of the outer cylinder 1. The outer cylinder 1 is made of stainless steel to improve overall strength, while the inner cylinder 2 is made of aluminum alloy to prevent rust. Insulation cotton 3, which is foamed cotton, is filled between the outer cylinder 1 and the inner cylinder 2. A heat-conducting coil 4, made of copper, is fixedly connected inside the inner cylinder 2. The exhaust pipe 14 is slidably connected inside the inner cylinder 2, with its top end penetrating... An exhaust valve 15 is fixedly connected to the outer cylinder 1, which can control the exhaust height inside the inner cylinder 2 to form a high-pressure cavity inside the inner cylinder 2, thereby controlling the water level. A fixing ring 16 is fixedly connected inside the inner cylinder 2, and a rotating cylinder 17 is rotatably connected inside the fixing ring 16. A hot water pipe 18 is fixedly connected inside the rotating cylinder 17. Rotating the rotating cylinder 17 and the hot water pipe 18 can change the position of the hot water pipe 18 to ensure that it is below the highest water level, thus achieving a stable drainage state. A fixing box 20 is fixedly connected to the outside of the outer cylinder 1. An adjustment component 21 is installed inside the fixing box 20, and a positioning component 22 is installed inside the fixing box 20.

[0022] The outdoor unit 5 has an evaporator 6 fixedly connected inside, a fan 7 located inside the outdoor unit 5 and at the front end of the evaporator 6, an expansion valve 9 fixedly connected to the bottom of the inner wall of the outdoor unit 5, a liquid storage tank 8 fixedly connected inside the outdoor unit 5 and on the side of the expansion valve 9 away from the evaporator 6, and a compressor 10 located inside the outdoor unit 5 and on the side of the evaporator 6 away from the expansion valve 9. The evaporator 6, liquid storage tank 8, expansion valve 9 and compressor 10 are connected by pipes. The heating efficiency can be improved and the power consumption reduced by the dual heating of the air and the combination of the vaporization of the fluorine medium and the compression of the compressor 10.

[0023] The compressor 10 is fixedly connected to a conduit 11 at its output end. One end of the conduit 11 extends into the inner cylinder 2 and is fixed to the input end of the heat-conducting coil 4. The output end of the heat-conducting coil 4 is fixedly connected to a return pipe 12, which is also fixedly connected to the input end of the liquid storage tank 8. A thermometer 13 is fixedly connected inside the inner cylinder 2 and is electrically connected to the main control board inside the outdoor unit 5 via a wire. This allows for monitoring of the water temperature and control of the opening and closing of the outdoor unit 5, ensuring the rational use of energy.

[0024] The adjustment component 21 includes a servo motor 211, which is fixed to the top of the fixed box 20. The output shaft of the servo motor 211 passes through the fixed box 20 and is fixedly connected to a lead screw 212. The bottom end of the lead screw 212 rotates with the top of the outer cylinder 1. The lead screw 212 is threadedly connected to a connecting plate 213. Two fixed rods 216 are symmetrically slidably connected inside the connecting plate 213, and the two ends of the two fixed rods 216 are fixed to the fixed box 20 and the outer cylinder 1, respectively. One end of the connecting plate 213 extends to the outside of the fixed box 20 and is fixed to the exhaust pipe 14. A toothed ring 215 is sleeved on the outside of the rotating cylinder 17. A toothed plate 214 is fixedly connected to the bottom of the connecting plate 213, and the toothed plate 214 meshes with the toothed ring 215. The height of the exhaust pipe 14 and the exhaust valve 15 can be adjusted, thereby changing the exhaust height inside the inner cylinder 2, controlling the position of the highest liquid level, and the rotating cylinder 17 and the hot water pipe 18 can be driven to rotate by the toothed plate 214 in cooperation with the toothed ring 215 to ensure stable drainage.

[0025] The positioning component 22 includes a vertical plate 222, a through hole 221 inside the connecting plate 213, a vertical plate 222 fixedly connected to the top of the outer cylinder 1, the top of the vertical plate 222 passing through the through hole 221 and fixed to the top of the inner wall of the fixed box 20, an electromagnetic induction array plate 223 fixedly connected to one side of the vertical plate 222, a permanent magnet 224 fixedly connected to the inner wall of the through hole 221, and the permanent magnet 224 in contact with the electromagnetic induction array plate 223, which can detect the height of the exhaust pipe 14 and calculate the currently set liquid level height by sliding distance, thereby replacing the function of the traditional liquid level detector. It does not require the installation of corresponding electrical components inside the inner cylinder 2, can accurately control the water level height, and improve electrical safety.

[0026] One end of the hot water pipe 18 extends into the inner cylinder 2, and the other end extends into the outside of the rotating drum 17 and is fixedly connected to a flexible hose 19, which can adapt to the rotation of the hot water pipe 18 and ensure stable water output. A cold water pipe 23 is fixedly connected inside the outer cylinder 1 to facilitate adding water into the inner cylinder 2 and ensure pressure balance inside. One end of the cold water pipe 23 extends into the inner cylinder 2. A drain pipe 24 is fixedly connected to the bottom of the inner cylinder 2, and the bottom end of the drain pipe 24 extends into the outside of the outer cylinder 1. A drain valve 25 is installed inside the drain pipe 24 to facilitate the discharge of sewage from the inner cylinder 2 and thus clean its interior.

[0027] The outer cylinder 1 is fixedly connected to a control panel 26. Multiple indicator lights 27 are fixedly connected to the outside of the outer cylinder 1 and above the control panel 26. The outdoor unit 5, the servo motor 211 and the indicator lights 27 are electrically connected to the control panel 26, which can centrally control the equipment and facilitate user operation.

[0028] In summary: The water level inside the inner cylinder 2 is adjusted according to water demand. The servo motor 211 is started via the control panel 26. The servo motor 211 drives the lead screw 212 to rotate. As the lead screw 212 rotates, it causes the connecting plate 213 to slide inside the fixed box 20. Simultaneously, the connecting plate 213 drives the exhaust pipe 14, exhaust valve 15, and toothed plate 214 to slide. The toothed plate 214, in conjunction with the toothed ring 215, drives the rotating drum 17 to rotate inside the fixed ring 16. The rotating drum 17 then drives the hot water pipe 18 to rotate, thereby changing the height of the hot water pipe 18 to match the height of the exhaust pipe 14, ensuring that the hot water pipe 18 is lower than the bottom of the exhaust pipe 14. Water is injected into the inner cylinder 2 through the cold water pipe 23. At this time, the air above the inner cylinder 2 is discharged through the exhaust pipe 14 and exhaust valve 15. When the liquid level inside the inner cylinder 2 reaches the position of the exhaust pipe 14, water enters the exhaust pipe 14 and seals the exhaust valve 15. At this point, the gas inside the inner cylinder 2 cannot be discharged. Figure 3As shown, a high-pressure gas area is formed at the top of the inner cylinder 2, preventing water from continuing to be added inside the inner cylinder 2, thus controlling the liquid level. When the connecting plate 213 moves, it drives the permanent magnet 224 to slide. After the permanent magnet 224 slides on the electromagnetic induction array plate 223, it can sense the specific position of the permanent magnet 224. The current set liquid level can be calculated by the sliding distance, thus replacing the function of a traditional liquid level detector. There is no need to install corresponding electrical components inside the inner cylinder 2. The outdoor unit 5 is started through the control panel 26. At this time, the compressor 10 compresses the low-temperature refrigerant into a high-temperature and high-pressure gas, which enters the heat conduction coil 4 through the conduit 11. At this time, the heat conduction coil 4 can conduct heat inside the inner cylinder 2, thereby heating the water inside the inner cylinder 2. The cooled refrigerant becomes liquid under pressure and is then... The return pipe 12 returns the refrigerant to the liquid storage tank 8. The liquid refrigerant enters the evaporator 6 through the expansion valve 9 and rapidly evaporates into a gaseous state under the action of the evaporator 6, absorbing heat. At the same time, the fan 7 draws outside air into the outdoor unit 5 and passes it through the evaporator 6. At this time, the heat in the air is absorbed by the evaporator 6. The refrigerant that has absorbed heat returns to the compressor 10 to enter the next cycle, thereby continuously heating the water inside the inner cylinder 2. The temperature of the water inside the inner cylinder 2 is monitored by the thermometer 13, and the status of the equipment can be judged by the indicator light 27. When the water temperature inside the inner cylinder 2 reaches the set value, the outdoor unit 5 is turned off. When hot water is needed, the control valve at the end of the hose 19 is opened. The drain valve 25 is opened, and the sewage inside the inner cylinder 2 can be discharged through the drain pipe 24 to clean the inside.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
