Description

Technical Field

[0001] This utility model relates to the technical field of air source water heater components, and in particular to a pressurized water storage tank structure for an air source water heater device. Background Technology

[0002] Air source heat pump water heaters, also known as "air source heat pump water heaters," work on a principle very similar to that of air conditioners. They use a small amount of electricity to drive the compressor. The high-pressure liquid working fluid evaporates into a gaseous state in the evaporator after passing through the expansion valve, absorbing a large amount of heat energy from the air. The gaseous working fluid is then compressed by the compressor into a high-temperature, high-pressure liquid state, which then enters the condenser to release heat and heat the water. This cycle continues, heating the water to 50℃~65℃.

[0003] like Figure 3 As shown, this is the structure of a pressurized water storage tank installed on a previous generation of air source heat pump water heaters. Similar to most pressurized water storage tanks on the market, it has a thickened tank structure, with the entire tank body hidden between the outer cylinder and the foam insulation layer. However, this type of water storage tank structure has the following shortcomings in actual use: Although the pressure-bearing capacity is enhanced compared to ordinary water storage tanks, the internal pressure of the tank is relatively high during actual use, which can easily lead to abnormal problems such as tank deformation, pressure rupture at the pipe opening, and water leakage in the pipeline, thereby reducing the safety and stability of the water storage tank in actual use.

[0004] In view of this, it is particularly important to design and manufacture a pressure-bearing water storage tank structure that can adaptively adjust the pressure when the internal pressure increases and improve the tank's ability to withstand internal pressure, for application in air source heat pump water heaters. Utility Model Content

[0005] The purpose of this utility model is to provide a pressurized water storage tank structure for an air-source heat pump water heater in order to solve the problem.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressurized water storage tank structure for an air-source heat pump water heater includes an outer cylinder, a tank body disposed inside the outer cylinder, a foamed insulation layer filling the gap between the outer cylinder and the tank body, a lower end cover detachably installed at the lower end of the outer cylinder, and an upper end cover detachably installed at the upper end of the outer cylinder. The upper end of the tank body is fixedly connected to an upwardly protruding pressure regulating box, and the inner side of the pressure regulating box is provided with a pressure stabilizing mechanism for dynamically adjusting according to the internal pressure of the tank.

[0008] As a further description of the above technical solution:

[0009] The voltage stabilizing mechanism includes a lifting valve plate movably installed at the lower end of the voltage regulating box, an inner thread seat integrally fixed at the middle of the upper part of the lifting valve plate, a T-shaped spiral tube screwed onto the inner thread seat by external threads and extending upward through the upper end cover, and V-shaped spring pieces arranged in a ring array installed at the upper end of the lifting valve plate and abutting against the inner side of the upper end of the voltage regulating box.

[0010] As a further description of the above technical solution:

[0011] The outer periphery of the lifting valve plate is fitted with a sealing ring that abuts against the inner wall of the pressure regulating box.

[0012] As a further description of the above technical solution:

[0013] The T-shaped spiral tube has multiple vertically distributed ventilation holes arranged in a ring array on its exterior.

[0014] As a further description of the above technical solution:

[0015] The upper end cap has a stepped hole in the middle for accommodating the upper end of the T-shaped spiral tube.

[0016] As a further description of the above technical solution:

[0017] The top right end of the tank is connected to a hot water pipe that penetrates the outer cylinder, and the bottom right end of the tank is connected to a cold water pipe that penetrates the outer cylinder.

[0018] As a further description of the above technical solution:

[0019] An air heat exchange copper pipe is installed inside the tank, between the hot water pipe and the cold water pipe, and extends to the right through the outer cylinder.

[0020] As a further description of the above technical solution:

[0021] The right end of the tank is located below the cold water pipe and is connected to a drain pipe.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0023] In this invention, the original tank body has been scientifically and rationally improved. A pressure regulating box, a lifting valve plate, a V-shaped spring, and a T-shaped spiral tube are installed at the upper end of the tank body. Under normal conditions, the lifting valve plate is located at the bottom of the pressure regulating box under the action of gravity and the elastic force of the V-shaped spring, similar to the conventional integral tank structure. When the internal pressure of the tank increases, the internal pressure will resist the action of gravity of the lifting valve plate and the elastic force of the V-shaped spring, causing the lifting valve plate to move upward in the pressure regulating box. This increases the pressure-bearing space inside the tank, ensuring that the internal pressure of the tank is within the normal range. This structure can achieve adaptive pressure stabilization operation of the tank when the internal pressure increases, reducing the occurrence of abnormal problems such as deformation when the internal pressure of the tank exceeds the limit, pressure rupture at the pipe opening, and water leakage in the pipeline, thereby improving the safety and stability of the water storage tank in actual use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 are within the protection scope of the present utility model.

[0030] Please see Figure 1-3This utility model provides a technical solution: a pressurized water storage tank structure for an air source heat pump water heater, including an outer cylinder 1, a tank body 2 disposed inside the outer cylinder 1, a foamed insulation layer 3 filling the gap between the outer cylinder 1 and the tank body 2, a lower end cover 101 detachably installed at the lower end of the outer cylinder 1 and an upper end cover 102 detachably installed at the upper end of the outer cylinder 1, and an upwardly protruding pressure regulating box 205 fixedly connected to the upper end of the tank body 2. The inner side of the pressure regulating box 205 is provided with a pressure stabilizing mechanism for dynamically adjusting according to the internal pressure of the tank body 2.

[0031] Specifically, such as Figure 1 and Figure 2 As shown, the voltage stabilizing mechanism includes a lifting valve plate 4 movably installed at the lower end of the voltage regulating box 205, an inner thread seat 401 integrally fixed at the middle of the upper end of the lifting valve plate 4, a T-shaped spiral tube 6 screwed onto the inner thread seat 401 by an external thread 601 and extending upward through the upper end cover 102, and V-shaped spring pieces 5 arranged in a ring array on the upper end of the lifting valve plate 4 and abutting against the inner side of the upper end of the voltage regulating box 205.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, a sealing ring 402 is installed on the outer periphery of the lifting valve plate 4, which abuts against the inner wall of the pressure regulating box 205. This can dynamically seal the connection gap between the lifting valve plate 4 and the pressure regulating box 205, improving the airtightness between the lifting valve plate 4 and the pressure regulating box 205. The T-shaped swivel tube 6 has multiple vertically distributed ventilation holes 602 arranged in a ring array on its outer side. This can discharge the air in the upper half of the lifting valve plate 4 and the pressure regulating box 205 to the outside environment, preventing the pressure in the upper half of the pressure regulating box 205 from resisting the upward movement of the lifting valve plate 4. The upper end cover 102 has a stepped hole 103 in the middle for accommodating the upper end of the T-shaped swivel tube 6. Under normal conditions, the uppermost end of the T-shaped swivel tube 6 is hidden and stored in the stepped hole 103. When the lifting valve plate 4 is pressed and moves upward, the T-shaped swivel tube 6 can move upward in the stepped hole 103.

[0033] Specifically, such as Figure 1-3 As shown, a hot water pipe 201 is connected to the top right end of the tank 2, penetrating the outer cylinder 1, to facilitate the discharge of heated hot water out of the tank 2. A cold water pipe 203 is connected to the bottom right end of the tank 2, penetrating the outer cylinder 1, to facilitate the entry of cold water to be heated into the tank 2. An air heat exchange copper pipe 202 is installed inside the tank 2 between the hot water pipe 201 and the cold water pipe 203, penetrating the outer cylinder 1 to the right. When hot air enters the air heat exchange copper pipe 202, the air heat exchange copper pipe 202 can absorb the heat of the hot air and conduct it outward to the water in the tank 2, realizing the contact heating operation of the water in the tank 2. A drain pipe 204 is connected to the right end of the tank 2 below the cold water pipe 203. When the drain pipe 204 is opened, the wastewater containing impurities in the lower half of the tank 2 can be flushed out, thereby realizing the sewage treatment inside the tank 2.

[0034] Working principle: In use, connect the hot water pipe 201, air heat exchange copper pipe 202, cold water pipe 203, and drain pipe 204 of tank 2 to the hot water supply pipeline, hot air supply pipeline, cold water pipeline, and drain pipe, respectively. The storage tank can then be installed between the air source heat pump water heater and the hot water supply pipeline. During daily use, the hot air generated by the air source heat pump water heater circulates into the air heat exchange copper pipe 202 to heat the water inside tank 2. The heated hot water is then discharged through the hot water pipe 201. As the temperature of the hot water inside tank 2 increases, the water temperature in tank 2... The internal pressure also increases accordingly. The internal pressure of tank 2 will act upward on the lifting valve plate 4, causing the lifting valve plate 4 to move inside the pressure regulating box 205. The internal pressure will resist the friction, gravity, and elastic force of the lifting valve plate 4 and the V-shaped spring 5 in advance. The lifting valve plate 4 moves upward inside the pressure regulating box 205, increasing the pressure-bearing space inside the tank 2. When the internal pressure of tank 2 is restored, under the action of the gravity of the lifting valve plate 4 and the elastic force of the V-shaped spring 5, the lifting valve plate 4 can be reset downward to the lower end of the pressure regulating box 205, realizing the adaptive adjustment of the internal pressure of the water storage tank.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
