Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, specifically to a filter structure for an air source heat pump heat exchanger. Background Technology

[0002] An air source heat pump is an energy-saving device that utilizes high-grade energy to transfer heat from a low-grade heat source (air) to a high-grade heat source. It is a type of heat pump. As the name suggests, a heat pump, like a pump, can convert low-grade heat energy (such as the heat contained in air, soil, and water) that cannot be directly used into usable high-grade heat energy, thereby saving some high-grade energy (such as coal, natural gas, oil, and electricity). Therefore, a grille needs to be installed at the air inlet of the unit to prevent large impurities from entering the unit's interior. The anti-scaling air source heat pump heat exchanger described in authorization announcement number CN220583190U uses a drive motor to rotate a rotating plate, which in turn rotates a cleaning plate around the outside of the spiral heat exchange tube. This prevents liquid inside the heat exchanger from settling and adhering to the spiral heat exchange tube, effectively preventing scaling inside the heat exchanger. However, the existing technology still has the following drawbacks:

[0003] 1. Existing technology is not easy to clean, and dust tends to accumulate after long-term use, which affects air circulation;

[0004] 2. The existing cleaning plate cannot be disassembled and replaced, making subsequent maintenance and replacement inconvenient.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a filter structure for an air source heat pump heat exchanger.

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is a filter structure for an air source heat pump heat exchanger, comprising:

[0008] The main body has a collection port on its lower inner wall;

[0009] A filter plate, wherein the filter plate is disposed inside the main body;

[0010] A cleaning component is disposed inside the main body. A lead screw is rotatably connected to the middle of the lower inner wall of the main body. A motor that works with the lead screw is fixedly connected to the upper outer wall of the main body. A slider is sleeved on the lead screw. Two guide rods that work with the slider are fixedly connected to the middle of the upper inner wall of the main body. A cleaning brush that works with the filter plate is fixedly connected to the front side of the slider.

[0011] Fixing components, two of which are respectively disposed at the rear ends of the filter plate.

[0012] As an improvement, the fixing component includes:

[0013] A locking block, which is fixedly connected to the rear side of the filter plate;

[0014] Two fixing blocks are fixedly connected to the inner wall of the main body;

[0015] Guide holes, the two guide holes are respectively opened on opposite sides of the two fixing blocks;

[0016] The two damping rods are respectively fixedly connected to the inner walls of the two guide holes, and springs are sleeved on the side walls of the damping rods;

[0017] Two fixed balls are respectively fixedly connected to the opposite ends of two damping rods.

[0018] As an improvement, two limiting holes are provided on both the upper and lower sides of the filter plate. A telescopic rod is fixedly connected to the inner wall of the limiting hole. A spring is sleeved on the side wall of the telescopic rod. A retaining ball is fixedly connected to the end of the telescopic rod near the main body.

[0019] As an improvement, two grooves are provided on the upper and lower inner walls of the main body for use with a ball.

[0020] As an improvement, two handles are fixedly connected to the front side of the filter plate.

[0021] As an improvement, a fixing frame for use with the collection port is fixedly connected to the lower outer wall of the main body, and a collection box is provided inside the fixing frame.

[0022] As an improvement, two limiting blocks are fixedly connected to the lower outer wall of the collection box, and two limiting grooves are opened on the lower inner wall of the fixing frame to cooperate with the limiting blocks.

[0023] The advantages of this utility model compared with the prior art are as follows: 1. This utility model has a cleaning component inside the main body. By starting the motor, the lead screw can be driven to rotate, which causes the slider to start moving along the guide rod. At this time, the cleaning brush will clean the dust attached to the filter plate, so that the dust falls from the collection port to the outside of the main body, avoiding dust accumulation and blockage, which would affect the normal operation of the heat exchanger.

[0024] 2. This utility model has a fixing component on the back side of the filter plate. By sliding the filter plate along the inner wall of the main body, the locking block is also inserted between the two fixing blocks. Under the action of the damping rod and the spring, the fixing ball will stick tightly to the side wall of the locking block and fix it to the filter plate. When disassembling, the above operation can be reversed. It is convenient, quick and easy to maintain and replace. With the telescopic rod and the locking ball, the fixing effect can be further improved and the stability of the device can be guaranteed. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] Example 1:

[0044] like Figures 1 to 5 As shown, this embodiment proposes a filtration structure for an air source heat pump heat exchanger, including: a main body 1, a filter plate 2, a cleaning component 4, and a fixing component 5. The rear outer wall of the main body 1 is fixedly connected to the heat exchanger, serving as a channel for air circulation in the heat exchanger. A collection port is provided on the lower inner wall of the main body 1 to facilitate subsequent cleaning of debris inside.

[0045] The filter plate 2 is located inside the main body 1. Two handles 3 are fixedly connected to the front side of the filter plate 2, so that the user can control the movement of the filter plate 2 by holding the handles 3.

[0046] The cleaning component 4 is located inside the main body 1. A lead screw 41 is rotatably connected to the middle of the lower inner wall of the main body 1. A motor 42, which works with the lead screw 41, is fixedly connected to the upper outer wall of the main body 1. The output end of the motor 42 can rotate in two directions and passes through the side wall of the main body 1 and is fixedly connected to the lead screw 41. A slider 43 is sleeved on the lead screw 41. The inner wall of the slider 43 has threads that work with the lead screw 41. Two guide rods 44, which work with the slider 43, are fixedly connected to the middle of the upper inner wall of the main body 1. The guide rods 44 pass through the slider 43 and slide with it to restrict the movement of the slider 43 and prevent it from rotating. A cleaning brush 45, which works with the filter plate 2, is fixedly connected to the front of the slider 43. The front of the cleaning brush 45 abuts against the filter plate 2. By starting the motor 42, the lead screw 41 can be driven to rotate, causing the slider 43 to start moving along the guide rods 44. At this time, the cleaning brush 45 will clean the dust attached to the filter plate 2, so that the dust falls from the collection port to the outside of the main body 1, avoiding dust accumulation and blockage, which would affect the normal operation of the heat exchanger.

[0047] Two fixing components 5 are respectively set at both ends of the rear side of the filter plate 2. The fixing components 5 include: a locking block 51, a fixing block 52, a guide hole 53, a damping rod 54, and a fixing ball 55. The locking block 51 is fixedly connected to the rear side of the filter plate 2. The two fixing blocks 52 are fixedly connected to the inner wall of the main body 1. The two guide holes 53 are respectively opened on the opposite side of the two fixing blocks 52. The two damping rods 54 are respectively fixedly connected to the inner wall of the two guide holes 53. A spring is sleeved on the side wall of the damping rod 54. The two fixing balls 55 are respectively fixedly connected to the opposite end of the two damping rods 54. By sliding the filter plate 2 along the inner wall of the main body 1, the locking block 51 is also inserted between the two fixing blocks 52. Under the action of the damping rod 54 and the spring, the fixing ball 55 will be tightly attached to the side wall of the locking block 51 and fix it to the filter plate 2. When disassembling, the above operation can be reversed. It is convenient, quick, and easy to maintain and replace.

[0048] Example 2:

[0049] The solution in Example 1 will be further described below with reference to its specific working method.

[0050] Two limiting holes 6 are provided on the upper and lower sides of the filter plate 2. A telescopic rod 7 is fixedly connected to the inner wall of the limiting hole 6. A spring is sleeved on the side wall of the telescopic rod 7. A retaining ball 8 is fixedly connected to the end of the telescopic rod 7 near the main body 1. The size of the retaining ball 8 is slightly smaller than that of the limiting hole 6, so that it can retract into the limiting hole 6. Two grooves are provided on the inner walls of the upper and lower sides of the main body 1 to cooperate with the retaining ball 8, so that the retaining ball 8 can be embedded in the groove and prevent it from continuing to slide. Through the cooperation of the telescopic rod 7 and the spring, the retaining ball 8 can always be retracted into the limiting hole 6 as the filter plate 2 slides along the inner wall of the main body 1. After the filter plate 2 contacts the fixing block 52, the retaining ball 8 will also be embedded in the groove under the action of the elastic force, thereby further improving the fixing effect of the filter plate 2 without affecting the disassembly of the filter plate 2 and ensuring the stability of the device.

[0051] Example 3:

[0052] The following section provides a further description of the scheme in Example 2, focusing on its specific working method. See the description below for details:

[0053] A fixed frame 9 is fixedly connected to the lower front end of the main body 1. A collection box 10 is set inside the fixed frame 9 to collect dust and other debris falling from the collection port for easy handling by staff. A handle 3 is fixedly connected to the front outer wall of the collection box 10. Two iron limit blocks are fixedly connected to the lower outer wall of the collection box 10. A limit groove is opened on the lower inner wall of the fixed frame 9 to cooperate with the limit blocks. A magnet is embedded in the inner wall of the limit groove. The magnet can attract the limit block and fix it inside the fixed frame 9 without human intervention, preventing the collection box 10 from falling.

[0054] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and components is omitted in the specific implementation of this disclosure. To ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0055] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
