Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically to a detachable filter frame for a dehumidifier. Background Technology

[0002] In the daily use of dehumidifiers, to prevent dust, lint, and other impurities in the air from entering the equipment and affecting its operating efficiency and service life, a filter assembly is usually installed at the air inlet. The filter frame of the dehumidifier is an important part of the filtration system. Its main function is to fix the filter components and ensure that the air is filtered before entering the dehumidifier for dehumidification. The structural design of the filter frame is directly related to the stability of the filtration effect and the convenience of later maintenance. It is one of the key components to ensure the long-term effective operation of the dehumidifier.

[0003] Existing dehumidifier filter frames mostly adopt fixed structures or complex bolt connections. When cleaning or replacing the filter, these structures often require disassembling multiple parts with tools, making the operation cumbersome. This not only increases the maintenance difficulty and time cost for users, but also may cause wear and tear on the parts due to frequent disassembly, affecting the connection stability and filtration effect of the filter frame. In addition, some detachable structures lack effective dust prevention measures during disassembly, which can easily lead to accumulated dust and lint falling into the dehumidifier and causing secondary pollution. Therefore, we propose a detachable filter frame for dehumidifiers. Utility Model Content

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a detachable filter frame for a dehumidifier, comprising: The dehumidifier body and side panels are provided. The two opposite side walls of the dehumidifier body are provided with two side panels that are symmetrically distributed on the axis. The side panels are connected to the side walls of the dehumidifier body by means of matching screws. A removable filter assembly is disposed on the side wall of the dehumidifier body, and the removable filter assembly is correspondingly slidably engaged with the inside of the side wall of the dehumidifier body.

[0006] Preferably, the dehumidifier body has an air inlet on its side wall, the air inlet has a rectangular groove structure, and guide holes are provided at both ends of the two opposite sides of the vertically placed air inlet. The two opposite side walls of the dehumidifier body have two axially symmetrically distributed mating grooves, which are perpendicular to the air inlet and are positioned between the two guide holes.

[0007] Preferably, the mating groove has a rectangular structure, and the inner wall of the mating groove is provided with a sliding groove 1, which is parallel to the guide hole. The sliding groove 1 is provided with an inlet / outlet slot on the shaft end on the side corresponding to the air inlet. The bottom of the sliding groove 1 is provided with a sliding groove 2, which is perpendicular to the sliding groove 1, and the top of the sliding groove 2 is connected to the sliding groove 1.

[0008] Preferably, the side plate is connected to the four corners of the inner wall of the mating groove by adapter screws, and the end face of the side plate side wall is provided with a sliding groove three, which corresponds to the sliding groove two.

[0009] Preferably, the detachable filter assembly includes a mesh frame, a mesh plate, a spring component one, and a spring component two. The main body of the detachable filter assembly is the mesh frame, and a mesh plate is inserted into the mesh frame. The mesh frame is provided with two sets of spring components one and two in an axisymmetrically distributed manner at the inner end of the side wall of the dehumidifier body. Spring component one is placed inside the slide groove two, and spring component two is placed inside the shaft end of the slide groove one.

[0010] Preferably, the mesh frame is engaged with the air inlet, and two support frames are provided on the two opposite end faces of the mesh frame in an axisymmetrical manner. The support frames have an X-shaped structure, and a placement slot is opened on the outer side of the top of the mesh frame, and a temporary slot is opened on the inner side of the top of the mesh frame. Both the placement slot and the temporary slot are placed between the two support frames. Guide rods are welded to the four corners of the back side of the mesh frame. The guide rods are slidably connected to the guide holes. A sliding rod is provided between the two vertical guide rods on the side wall of the mesh frame.

[0011] Preferably, the slide rod is slidably connected to the inlet and outlet slots, and the slide rod shaft end is provided with a clamping block. The clamping block is slidably connected to the inside of the first slide groove, and the shaft end of the clamping block is in contact with the shaft end of the second spring. The bottom of the clamping block is provided with a first clamping groove and a second clamping groove. The first clamping groove and the second clamping groove have the same structure, and the first clamping groove has a triangular groove structure.

[0012] Preferably, the top of the spring component is provided with a locking block, which is engaged with the locking groove 1 and the locking groove 2, and the top side wall of the spring component is provided with a control block, which is slidably connected with the sliding groove 3.

[0013] Compared with the prior art, this utility model provides a detachable filter frame for dehumidifiers, which has the following advantages: 1. This dehumidifier uses a detachable filter frame, which effectively reduces secondary dust pollution during maintenance. When the filter is removed, the frame moves to a temporary position by the rebound force of spring component two. At this time, the partition inserted into the temporary slot can effectively block the dust and lint that falls off during the removal of the filter, preventing impurities from entering the dehumidifier body through the air inlet. This design avoids the problem of impurities falling directly into the equipment in the traditional disassembly method, reduces the risk of equipment failure caused by internal dust accumulation, and reduces the frequency and difficulty of cleaning the inside of the dehumidifier later, ensuring the long-term stability of the dehumidifier and the reliability of the filtration effect.

[0014] 2. This dehumidifier uses a detachable filter frame. The easy-to-remove filter assembly effectively improves stability during installation and use. During installation, the locking block at the top of spring component one precisely engages with the locking groove at the bottom of the slide rod. Combined with the axial compression force of spring component two, the filter frame can be firmly fixed in the working position, preventing the filter frame from loosening or shifting due to vibration during dehumidifier operation. This ensures effective filtration coverage of the air inlet by the filter plate. During disassembly and maintenance, the locking block compresses spring component one, causing the locking to fail. The filter frame moves under the rebound force of spring component two until the locking block engages with the locking groove two, achieving temporary fixation and preventing the filter frame from accidentally detaching from the dehumidifier body. This dual locking design ensures reliable connection during normal use and simplifies disassembly procedures. Stable locking and unlocking can be achieved without the need for additional tools, improving the ease of use and structural durability of the filter frame. Attached Figure Description

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.

[0018] Please see Figure 1-5 A detachable filter frame for a dehumidifier, comprising: The dehumidifier body 1 and the side plate 6 are provided. The two opposite side walls of the dehumidifier body 1 are provided with two side plates 6 that are symmetrically distributed on the axis. The side plates 6 are connected to the side walls of the dehumidifier body 1 by means of matching screws. The removable filter assembly is located on the side wall of the dehumidifier body 1, and the removable filter assembly is slidably engaged with the inside of the side wall of the dehumidifier body 1.

[0019] Furthermore, the dehumidifier body 1 has an air inlet 7 on its side wall. The air inlet 7 has a rectangular groove structure. The air inlet 7 has guide holes 11 at both ends of its two opposite sides. The dehumidifier body 1 also has two axially symmetrically distributed mating grooves 8 on its two opposite side walls. The mating grooves 8 are perpendicular to the air inlet 7 and are positioned between the two guide holes 11.

[0020] Furthermore, the mating groove 8 has a rectangular structure, and the inner wall of the mating groove 8 is provided with a sliding groove 9. The sliding groove 9 is parallel to the guide hole 11, and the sliding groove 9 is provided with an inlet / outlet slot 12 on the shaft end on the side of the air inlet 7.

Both the placement slot 14 and the temporary slot 15 are placed between the two support frames 13. Guide rods 16 are welded to the four corners of the back side of the mesh frame 2. The guide rods 16 are slidably connected to the guide holes 11. A sliding rod 17 is provided between the two vertical guide rods 16 on the side wall of the mesh frame 2. The X-shaped support frames 13 can improve the structural strength of the mesh frame 2 and effectively protect the mesh plate 3. The sliding connection between the guide rods 16 and the guide holes 11 effectively ensures the stability of the movement of the mesh frame 2.

[0024] Furthermore, the slide rod 17 is slidably connected to the inlet / outlet slot 12. The shaft end of the slide rod 17 is provided with a clamping block 18, which is slidably connected to the inside of the first slide groove 9. The shaft end of the clamping block 18 is in contact with the shaft end of the second spring 5. The bottom of the clamping block 18 is provided with a first groove 19 and a second groove 20. The first groove 19 and the second groove 20 have the same structure. The first groove 19 has a triangular groove structure. The first groove 19 provides a clamping effect, while the second groove 20 prevents the mesh frame 2 from detaching from the dehumidifier body 1 and plays a limiting role.
