Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, and in particular to an auxiliary device for improving the performance of air source heat pumps in low-temperature environments. Background Technology

[0002] Low-temperature air source heat pumps are energy-saving devices that can extract abundant low-grade energy from the ambient atmosphere and convert it into high-grade heat energy for people to use. They are easy to use, have low installation costs, and are widely used. However, due to temperature differences, especially in winter, a layer of frost will condense on the surface of the heat exchanger of existing low-temperature air source heat pumps. As the frost accumulates on the surface of the heat pump over time, it will reduce the efficiency of the heat pump and thus waste working resources.

[0003] Existing technologies, such as Chinese Patent Publication No. CN220017865U, disclose a low-temperature air source heat pump antifreeze and defrosting device, including a mounting box. The outer surface of the mounting box is symmetrically hinged with doors. A pump body is clamped inside the mounting box. A heat dissipation box is located at the top of the mounting box, and a cooling fan is connected inside the heat dissipation box. A clamping mechanism for holding the pump body is provided inside the mounting box. The clamping mechanism includes a bidirectional screw and a sliding rod. Clamping plates are symmetrically inserted into both the bidirectional screw and the sliding rod. The pump body is located between the two clamping plates. A heating tube is located inside the clamping plates. An antifreeze layer is located inside the clamping plates near the pump body. Two slide rails are symmetrically arranged at the bottom of the mounting box, and a liquid collection tank slides on the slide rails. This device has good antifreeze and defrosting effects, and being located outside the pump body, it does not affect its working effect. Simultaneously, a solar panel is provided to provide power for the antifreeze and defrosting operation, making it energy-saving and environmentally friendly. However, this utility model uses heating pipes on both sides of the pump body for defrosting, which has a relatively poor defrosting effect on other surfaces. Furthermore, the water formed after defrosting is directly collected in the liquid tank, and the resulting moisture may affect the pump body again.

[0004] To address the issue of frost buildup on the surface of air source heat pumps in low-temperature environments, which can negatively impact performance, existing equipment typically employs methods such as fixed heating pipes near the pump body for defrosting. This method has a limited heating range, making it difficult to effectively defrost all surfaces of the pump body and potentially affecting normal operation. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the surface of an air source heat pump is prone to frost formation in low-temperature environments, which affects its performance. Therefore, this invention proposes an auxiliary device to improve the performance of an air source heat pump in low-temperature environments.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an auxiliary device for improving the performance of an air source heat pump in a low-temperature environment, comprising a mounting box, a placement plate, a pump body, and a defrosting mechanism. The placement plate is fixedly connected to the inner wall of the mounting box, the pump body is disposed on the surface of the placement plate, and the defrosting mechanism is disposed on the surface of the mounting box. The defrosting mechanism includes a receiving groove, which is opened inside the mounting box. A motor is fixedly mounted on the surface of the receiving groove, and a screw is fixedly connected to the output end of the motor. A sleeve is threadedly connected to the surface of the screw, and a movable plate is fixedly connected to the surface of the sleeve. A heating tube is fixedly mounted on the surface of the movable plate, and a baffle is fixedly connected to the end of the heating tube away from the movable plate. A limit rod is fixedly connected to the surface of the receiving groove, and the surfaces of the movable plate and the limit rod are slidably connected.

[0007] Furthermore, the number of the limiting rods is two sets and they are arranged symmetrically, and an anti-detachment disc is fixedly connected to the surface of the limiting rods. The number of the heating tubes is two sets and they are arranged symmetrically.

[0008] Furthermore, a partition is fixedly connected to the surface of the receiving groove, the screw is rotatably connected to the inner wall of the partition, and the motor and the sleeve are respectively arranged on both sides of the partition.

[0009] Furthermore, a sealing ring one is fixedly connected to the surface of the movable plate, and a sealing ring two is fixedly connected to the surface of the baffle. Both the sealing ring one and the sealing ring two are adapted to the receiving groove.

[0010] Furthermore, the surface of the mounting box is provided with a drainage mechanism, which includes an inclined groove that is formed on the inner wall of the mounting box. The surface of the placement plate is provided with a water leakage hole, and the surface of the receiving groove is provided with a flow guide groove that is positioned between the movable plate and the baffle.

[0011] Furthermore, a drainage box is fixedly connected to the surface of the flow channel, a spring is fixedly connected to the inner wall of the drainage box, a pressure plate is fixedly connected to the surface of the spring, and a sealing ring three is fixedly connected to the surface of the pressure plate. The sealing ring three is adapted to the inner wall of the drainage box.

[0012] Furthermore, a drain pipe is continuously connected to the surface of the drain tank, the drain pipe is located on the lower side of the pressure plate, the drain pipe is inclined, and a water collection tank is fixedly connected to the surface of the mounting box, and the drain pipe is continuously connected to the surface of the water collection tank.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a defrosting mechanism, when the pump body is frosted, the heating tube is first activated to heat the air between the movable plate and the baffle. Then, the motor is activated to drive the screw to rotate, which causes the sleeve to drive the movable plate to slide along the limit rod. The baffle then slides outward and no longer blocks the receiving groove, allowing the hot air to be released into the mounting box. The hot air rises and contacts the pump body to defrost. After defrosting, the hot air cools down and falls. Then, the motor is activated to reverse, causing the movable plate and the baffle to reset, and the cooled air is drawn into the receiving groove. The above operation is repeated until defrosting is complete. By setting up a defrosting mechanism, the characteristics of hot air rising and cold air falling can be used to effectively defrost all surfaces of the pump body, avoiding affecting the normal operation of the pump body, thereby improving the performance of the pump body in low-temperature environments and effectively improving the durability of the equipment.

[0015] 2. In this utility model, by setting a drainage mechanism, the water formed after defrosting falls to the bottom of the mounting box through the drain hole and the inclined groove. When the movable plate and the baffle slide into the receiving groove, in addition to drawing in cold air, they also draw in accumulated water. The accumulated water enters the drain box through the guide groove, presses the pressure plate downward and tightens the spring, and after the drain pipe is exposed, the accumulated water flows into the water collection tank. Then, under the action of the spring rebound, the pressure plate returns to its original position, continuing to isolate the receiving groove and the drain pipe, so as to avoid affecting the heating of the air. By setting a drainage mechanism, the water formed after defrosting can be properly collected, avoiding the pump body from getting damp due to moisture and the accumulated water from freezing in the low temperature environment, thus effectively improving the convenience of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an auxiliary device for improving the performance of an air source heat pump in a low-temperature environment, including a mounting box 1, a placement plate 2, a pump body 3 and a defrosting mechanism 4. The placement plate 2 is fixedly connected to the inner wall of the mounting box 1, the pump body 3 is disposed on the surface of the placement plate 2, and the defrosting mechanism 4 is disposed on the surface of the mounting box 1.

[0024] The specific setup and function of its defrosting mechanism 4 and drainage mechanism 5 will be explained below.

[0025] In this embodiment: the defrosting mechanism 4 includes a receiving groove 401, which is opened inside the mounting box 1. A motor 402 is fixedly installed on the surface of the receiving groove 401. A screw 403 is fixedly connected to the output end of the motor 402. A sleeve 404 is threadedly connected to the surface of the screw 403. A movable plate 405 is fixedly connected to the surface of the sleeve 404. A heating tube 406 is fixedly installed on the surface of the movable plate 405. A baffle 407 is fixedly connected to the end of the heating tube 406 away from the movable plate 405. A limit rod 408 is fixedly connected to the surface of the receiving groove 401. The surfaces of the movable plate 405 and the limit rod 408 are slidably connected.

[0026] The effect achieved by the above components is as follows: the heating tube 406 is activated to heat the air between the movable plate 405 and the baffle 407, and then the motor 402 is activated to drive the screw 403 to rotate, which in turn causes the sleeve 404 to drive the movable plate 405 to slide along the limit rod 408. The baffle 407 slides outward and no longer blocks the receiving groove 401, so that the hot air is released into the mounting box 1. The hot air rises and contacts the pump body 3 to defrost. After the hot air defrosts, it cools down and falls downward. Then the motor 402 is activated to reverse the direction, so that the movable plate 405 and the baffle 407 are reset, and the cooled air is drawn into the receiving groove 401 for reheating.

[0027] Specifically, there are two sets of limiting rods 408 arranged symmetrically, and an anti-detachment disc 409 is fixedly connected to the surface of the limiting rods 408. There are two sets of heating tubes 406 arranged symmetrically.

[0028] The effects achieved by the above components are as follows: setting two sets of limiting rods 408 is to prevent the movable plate 405 from rotating with the screw 403 and to improve the stability of the movement; setting an anti-detachment disc 409 is to prevent the movable plate 405 from detaching from the limiting rods 408; and setting two sets of heating tubes 406 is to increase the heating efficiency.

[0029] Specifically, a partition plate 410 is fixedly connected to the surface of the receiving groove 401, a screw 403 is rotatably connected to the inner wall of the partition plate 410, and a motor 402 and a sleeve 404 are respectively arranged on both sides of the partition plate 410.

[0030] The effect achieved by the above components is as follows: the partition 410 is set to protect the motor 402 from the effects of water accumulation or moisture.

[0031] Specifically, a sealing ring 411 is fixedly connected to the surface of the movable plate 405, and a sealing ring 412 is fixedly connected to the surface of the baffle 407. Both the sealing ring 411 and the sealing ring 412 are adapted to the receiving groove 401.

[0032] The effect achieved by the above components is that the sealing ring 411 and sealing ring 412 are provided to increase the sealing between the movable plate 405 and the baffle 407 and the receiving groove 401.

[0033] Specifically, the surface of the mounting box 1 is provided with a drainage mechanism 5, which includes an inclined groove 51. The inclined groove 51 is opened on the inner wall of the mounting box 1. The surface of the placement plate 2 is provided with a water leakage hole 52. The surface of the receiving groove 401 is provided with a guide groove 53, which is located between the movable plate 405 and the baffle 407.

[0034] The effects achieved by the above components are as follows: the inclined groove 51 and the drain hole 52 are provided so that the water formed after defrosting falls into the bottom of the mounting box 1, and the guide groove 53 is provided so that when the accumulated water is sucked into the receiving tank 401, it can fall directly into the drain tank 54.

[0035] Specifically, a drainage tank 54 is fixedly connected to the surface of the flow channel 53, a spring 55 is fixedly connected to the inner wall of the drainage tank 54, a pressure plate 56 is fixedly connected to the surface of the spring 55, and a sealing ring 57 is fixedly connected to the surface of the pressure plate 56. The sealing ring 57 is adapted to the inner wall of the drainage tank 54.

[0036] The effects achieved by the above components are as follows: the drain tank 54 is set to temporarily contain accumulated water; the pressure plate 56 is set to isolate the receiving groove 401 and the drain pipe 58 when there is no water in the drain tank 54; the spring 55 is set to facilitate the reset of the pressure plate 56; and the sealing ring 57 is set to increase the sealing between the pressure plate 56 and the inner wall of the drain tank 54.

[0037] Specifically, a drain pipe 58 is connected through the surface of the drain tank 54. The drain pipe 58 is located on the lower side of the pressure plate 56 and is inclined. A water collection tank 59 is fixedly connected to the surface of the mounting box 1, and the drain pipe 58 is connected through the surface of the water collection tank 59.

[0038] The effects achieved by the above components are as follows: the inclined drain pipe 58 is set to facilitate the diversion of water in the drain tank 54 into the water collection tank 59, and the water collection tank 59 is set to facilitate proper collection of water and prevent water from remaining inside the mounting box 1 and affecting the normal operation of the pump body 3.

[0039] Working principle: By setting up a defrosting mechanism 4, when the pump body 3 is frosted, the heating tube 406 is first activated to heat the air between the movable plate 405 and the baffle 407. Then, the motor 402 is activated to drive the screw 403 to rotate, which in turn causes the sleeve 404 to drive the movable plate 405 to slide along the limit rod 408. The baffle 407 then slides outward and no longer blocks the receiving groove 401, allowing the hot air to be released into the mounting box 1. The hot air rises and contacts the pump body 3 to defrost. After defrosting, the hot air cools down and falls. Then, the motor 402 is activated to reverse, causing the movable plate 405 and the baffle 407 to reset, drawing the cooled air into the receiving groove 401. The above operation is repeated until defrosting is complete. By setting up a defrosting mechanism 4, the characteristics of hot air rising and cold air falling can be used to effectively defrost all surfaces of the pump body 3, avoiding affecting the normal operation of the pump body 3, thereby improving the performance of the pump body 3 in low-temperature environments and effectively improving the durability of the equipment.

[0040] Furthermore, by setting up a drainage mechanism 5, the water formed after defrosting falls to the bottom of the mounting box 1 through the drain hole 52 and the inclined groove 51. When the movable plate 405 and the baffle 407 slide into the receiving groove 401, in addition to drawing in cold air, they also draw in accumulated water. The accumulated water enters the drain box 54 through the guide groove 53, presses the pressure plate 56 downward and tightens the spring 55, and after the drain pipe 58 is exposed, the accumulated water flows into the water collection box 59. Then, under the rebound action of the spring 55, the pressure plate 56 returns to its original position, continuing to isolate the receiving groove 401 and the drain pipe 58, so as to avoid affecting the heating of the air. By setting up a drainage mechanism 5, the water formed after defrosting can be properly collected, avoiding moisture from causing the pump body 3 to become damp and the accumulated water from freezing in the low temperature environment, thus effectively improving the convenience of the equipment.
