Description

Technical Field

[0001] This utility model relates to the field of heat pump equipment technology, and in particular to an air intake dustproof structure for an air source heat pump water heater. Background Technology

[0002] An air source heat pump water heater is a device that uses an air source heat pump to heat water, primarily for domestic hot water supply. Its working principle is based on the reverse Carnot cycle; a compressor absorbs heat energy from the air, which is then transferred to a water tank via a refrigerant to heat cold water. It can achieve a constant water temperature supply around the clock without direct sunlight. Because of this, air source heat pump water heaters are relatively large in size, approaching 2 meters in height, and have a large internal water tank.

[0003] For example, the Chinese utility model patent with authorization announcement number CN214665205U specifically discloses an air source heat pump water heater unit. According to its disclosed technical content and drawings, it can be seen that a filter screen is set on the windward side of the first heat exchanger inside the inner cavity of the shell to filter dust and other debris. At the same time, an insertion hole is provided on the shell to facilitate the insertion or removal of the filter screen.

[0004] However, after the filter screen accumulates dust, it needs to be pulled out and cleaned. Because the existing air source heat pump water heater units are relatively tall, and the filter screen is fixed to the heat exchanger inside the casing by clamping, it is inconvenient for users to disassemble the filter screen, and it is easy to stir up the dust on the filter screen, resulting in a poor user experience. Utility Model Content

[0005] In order to overcome the defects of the existing technology, this utility model provides an air intake dustproof structure for an air source heat pump water heater, which solves the problem of inconvenient filter screen disassembly in the existing technology.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an air inlet dustproof structure for an air source heat pump water heater, comprising: The housing has an air inlet and an air outlet on its top surface. The air inlet has a groove along its edge, and an insertion hole is provided on the inner wall of one end of the groove. A filter assembly, wherein one end of the filter assembly is provided with a plug-in portion and the other end of the filter assembly is provided with a handle, the plug-in portion can be inserted into the plug hole, and the filter assembly is placed in the groove. As a further embodiment, the filter assembly includes a mesh cover and a filter sheet. The bottom surface of the mesh cover has a slot with an insertion end fixed along its edge. The filter sheet is inserted into the slot through the insertion end. The insertion part is fixed to one end of the mesh cover, and the handle is located at the other end of the mesh cover.

[0007] As a further embodiment, the filter includes a frame and a filter screen covering the frame.

[0008] As a further option, the frame is made of iron; The bottom of the groove is provided with a receiving box, and a magnet is placed inside the receiving box. The frame can be magnetically attracted to the magnet.

[0009] As a further solution, a perforation is provided at the other end of the mesh cover; The handle includes a pinchable part and a limiting part disposed at the bottom of the pinchable part. The size of the limiting part is larger than the through hole. The pinchable part passes through the through hole from bottom to top, and the limiting part abuts against the bottom surface of the mesh cover.

[0010] As a further embodiment, the pinchable part has slots on both sides of one end near the limiting part, and the edge of the perforation is engaged in the slot.

[0011] As a further option, the bottom of the groove is a mesh structure or an opening.

[0012] As a further option, the handle is made of rubber.

[0013] This utility model has at least one of the following beneficial effects: 1. By inserting the connector at one end of the filter assembly into the socket and placing the filter assembly within the groove, the filter assembly effectively filters dust and debris at the air inlet. Simultaneously, it provides vertical and horizontal restraint to prevent movement of the filter assembly. Furthermore, the filter assembly is installed at the air inlet on the top surface of the housing, reducing the user's vertical operating distance. When cleaning dust is required, simply lift the handle to disengage the connector from the socket, allowing for easy removal of the filter assembly.

[0014] 2. No dust is stirred up when disassembling the filter assembly, and it is easy to clean, resulting in a better user experience.

[0015] 3. Because of the blind-pull handle, it is also convenient for users to operate water heaters that are relatively tall. Attached Figure Description

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] As attached Figure 1-2 As shown in the figure, the air intake dustproof structure of an air source heat pump water heater provided in this embodiment includes a housing 1 and a filter assembly 2.

[0020] As attached Figure 1 As shown, the top surface of the housing 1 is provided with an air inlet 11 and an air outlet 12. The housing 1 has an inner cavity, and the air inlet 11, the inner cavity, and the air outlet 12 are connected in sequence to form an air duct. Air enters the inner cavity from the air inlet 11, exchanges heat in the inner cavity, and then exits from the air outlet 12. The arrangement and working principle of the components in the inner cavity are basically similar to the existing technology (CN214665205U - an air source heat pump water heater unit), so they will not be described in detail.

[0021] As attached Figure 2 As shown, the edge of the air inlet 11 is provided with a groove 13, and the inner wall of one end of the groove 13 is provided with an insertion hole 131. Specifically, the groove 13 can be machined into the edge of the air inlet 11 on the top surface of the housing 1 by integral molding, and the insertion hole 131 can be opened in the inner wall of one end of the groove 13. Alternatively, a separate groove 13 for air intake can be added at the air inlet 11.

[0022] As attached Figure 2 , 6As shown, the filter assembly 2 is used to filter air. One end of the filter assembly 2 has a connector 3, and the other end has a handle 4, which facilitates pulling the filter assembly 2 up by hand. The connector 3 can be inserted into the socket 131, and the filter assembly 2 is placed within the groove 13, which limits the movement of the filter assembly 2 in the vertical and horizontal directions. The handle 4 is made of rubber, providing a good overall feel.

[0023] In this embodiment, by inserting the connector 3 at one end of the filter assembly 2 into the socket 131 and placing the filter assembly 2 within the groove 13, the filter assembly 2 functions as a filter for dust and debris at the air inlet 11. Simultaneously, it provides vertical and horizontal positioning, preventing movement of the filter assembly 2. Furthermore, since the filter assembly 2 is installed at the air inlet 11 on the top surface of the housing 1, the user's vertical operating distance is reduced. When cleaning dust, simply lift the handle 4 to disengage the connector 3 from the socket 131, allowing for easy removal and cleaning of the filter screen 222 assembly without stirring up dust, resulting in a better user experience. Additionally, the blind-lift handle 4 facilitates operation of the tall water heater.

[0024] In some embodiments, as shown in the appendix Figure 2 , 6 As shown, the filter assembly 2 includes a mesh cover 21 and a filter element 22. The mesh cover 21 is a cover with mesh openings. A slot 212 with an insertion port 211 is fixed to the bottom surface of the mesh cover 21 along its edge. The filter element 22 is inserted into the slot 212 through the insertion port 211, thus fixing the filter element 22 to the mesh cover 21, forming the filter assembly 2. This also improves the structural strength of the filter assembly 2, preventing the filter element 22 from easily deforming and preventing dust generation. This makes it easier for users to install or remove the filter assembly 2 at the air inlet 11, resulting in a better user experience. The filter assembly 2 can be taken to the bathroom separately, and the filter element 22 can be removed for cleaning.

[0025] The mesh cover 21 is a rigid object with higher structural strength than the filter sheet 22 and will not easily deform. Therefore, the plug part 3 is fixed to one end of the mesh cover 21 by integral molding or welding, and the handle 4 is set at the other end of the mesh cover 21, making it easier for users to install or disassemble the filter assembly 2.

[0026] Based on the above embodiments, as shown in the appendix Figure 2 As shown, the filter 22 includes a frame 221 and a filter screen 222 covering the frame 221. The frame 221 serves as a structural frame, enabling the filter screen 222 to be tensioned, thus allowing the filter screen 222 to better filter dust and debris. It also facilitates the insertion of the filter 22 into the slot 212 from the insertion port 211.

[0027] In some embodiments, as shown in the appendix Figure 4-5 As shown, frame 221 is made of iron; a receiving box 5 is provided at the bottom of the groove 13, and a magnet 6 is placed inside the receiving box 5, allowing frame 221 to be magnetically attracted to the magnet 6. Specifically, the receiving box 5 is located at the end of the groove 13 away from the insertion hole 131, so that one end of the filter assembly 2 is inserted into the insertion hole 131 through the insertion part 3 for fixation, and the other end of the filter assembly 2 is fixed by the magnetic attraction between frame 221 and magnet 6. Furthermore, by placing the receiving box 5 at the bottom of the groove 13, the bottom of the groove 13 separates frame 221 from magnet 6, which maintains a certain magnetic attraction between frame 221 and magnet 6, while the magnetic attraction is not too strong, making it easy for users to lift handle 4 without stirring up dust due to excessive force.

[0028] As attached Figure 2 , 6 As shown in Figure 7, a through hole 213 is provided at the other end of the mesh cover 21; the handle 4 includes a pinchable part 41 and a limiting part 42 provided at the bottom of the pinchable part 41. The size of the limiting part 42 is larger than the through hole 213. The pinchable part 41 passes through the through hole 213 from bottom to top, and the limiting part 42 abuts against the bottom surface of the mesh cover 21, thereby attaching the handle 4 to the mesh cover 21. The user pinches the pinchable part 41 to pull up the filter assembly 2. Furthermore, slots 411 are provided on both sides of the end of the pinchable part 41 near the limiting part 42. The edge of the through hole 213 is locked in the slot 411, which can lock the handle 4 onto the mesh cover 21 and prevent the handle 4 from falling off.

[0029] In some embodiments, as shown in the appendix Figure 2-3 As shown, the bottom of the groove 13 is either a mesh structure 132 or an opening 133. Both the mesh structure 132 and the opening 133 can achieve the purpose of air intake. The mesh structure 132 is preferred, because the mesh structure 132 can also support the filter component 2 while allowing air to enter.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
