Description

Technical Field

[0001] This utility model relates to the field of air source heat pump technology, specifically an air source heat pump with an easy-to-remove filter. Background Technology

[0002] An air source heat pump is an environmentally friendly and energy-saving device that uses the reverse Carnot cycle principle to absorb low-grade heat energy from the air and convert it into high-grade heat energy for heating, cooling, or providing hot water.

[0003] In the prior art, in order to prevent debris from entering the heat pump unit, a mesh grille is usually installed on the side of the heat pump unit to block larger debris. In order to intercept smaller debris such as dust, a filter screen is covered near the inside of the grille to ensure that internal components such as the compressor are not damaged.

[0004] However, most grilles are bolted to the outside of the unit, while the filters are installed on the unit via a horizontal sliding rail. Over long-term operation, both the filters and grilles accumulate a large amount of dust, hair, and other impurities. This means that when cleaning and maintenance are needed, the grilles and filters must be disassembled individually, rather than simultaneously, potentially increasing disassembly time and making the process inconvenient. Therefore, we propose an air source heat pump with easily removable filters to effectively solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide an air source heat pump with an easy-to-disassemble filter, in order to solve the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution: an air source heat pump with an easy-to-remove filter screen, including a body, with grilles provided on both the front and rear sides of the body, the grilles being slidably arranged along the height direction of the body, and when the bottom of the grille slides to fit against the bottom plate of the body, the grille can be removed from the body, and a screen is detachably connected to the side of the grille facing the body.

[0007] Optionally, partitions are fixedly provided on both the front and rear sides of the machine body, and an installation area is formed between the partitions and the top of the machine body. Slide rails are fixedly provided on both the left and right sides of the installation area. The slide rails are distributed vertically, and the grille is slidably connected between the two slide rails along the height direction of the machine body. A disassembly area is formed between the partitions and the bottom of the machine body, and the grille can slide down from the installation area into the disassembly area to separate the grille from the machine body.

[0008] Optionally, the side projection shape of the grid is U-shaped, and the screen slides along the length of the grid.

[0009] Optionally, the side of the grid away from the screen has two first clamping grooves, which are symmetrically distributed from left to right. The side of the screen away from the grid has two second clamping grooves, which are respectively located at the positions of the two second clamping grooves and the positions of the two first clamping grooves. A clamping component is connected to the first and second clamping grooves on the same side. The clamping component is used to fix the screen to the inside of the grid.

[0010] Optionally, the clamping assembly includes a U-shaped clamp, which includes two clamping plates located in a first clamping groove and a second clamping groove, respectively. A sliding plate is fixedly mounted on the U-shaped clamp. The sliding plate is slidably connected to a slide rail in a vertical direction. The sliding plate is magnetically connected to the side of the grid and the screen via a magnetic plate. The magnetic plate is fixedly connected to the side of the sliding plate facing the grid and the screen.

[0011] Optionally, the slide rail is provided with threaded holes, and the first clamping groove, the second clamping groove, and the U-shaped clamp are all provided with through holes. When the grid is completely located inside the partition, the threaded holes and the through holes are in corresponding positions.

[0012] Compared with the prior art, this utility model provides an air source heat pump with an easy-to-remove filter, which has the following advantages:

[0013] 1. This utility model allows the filter plate to be detachably connected to the side of the grille facing the machine body, so that when the user disassembles and assembles the grille, the filter screen can be disassembled and assembled at the same time, making the disassembly and assembly process more convenient and faster;

[0014] 2. This utility model has an installation area and a disassembly area on the side of the machine body. A slide rail is provided in the installation area so that the grille can slide down from the installation area to the disassembly area. There is no obstruction of the slide rail in the disassembly area, so the grille can be directly disassembled. Compared with the traditional horizontal pull-out filter and flip-up grille, this disassembly and assembly method is suitable for compact installation scenarios and does not require too much reserved space for the disassembly and assembly of the grille and filter.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 7 An air source heat pump with an easily removable filter includes a body 1. Grilles 2 are provided on both the front and rear sides of the body 1. The grilles 2 are slidably disposed along the height of the body 1. When the bottom of the grille 2 slides down to be flush with the bottom plate of the body 1, the grille 2 can be removed from the body 1. A screen 3 is detachably connected to the side of the grille 2 facing the body 1. Therefore, when the grille 2 slides down to be flush with the bottom plate of the body 1, the screen 3 can be removed from the body 1 along with the grille 2, allowing the grille 2 and screen 3 to be disassembled and installed simultaneously for easy cleaning.

[0025] On the other hand, since the grille 2 is slidably installed along the height direction of the machine body 1, the screen 3 and the grille 2 slide up and down together on the side of the machine body 1. Most existing screens 3 are pull-out type, pulled out from the side of the machine body 1 along its length during disassembly. This requires a large space to be reserved on the outside of the unit for the screen 3 to ensure that the disassembly and assembly process is not obstructed. However, in this embodiment, both the grille 2 and the screen 3 are slidably removed along the height direction of the machine body 1. Therefore, no space needs to be reserved for disassembly and assembly, and the grille 2 and screen 3 are disassembled and assembled simultaneously, making the disassembly and assembly process more convenient and faster.

[0026] Furthermore, partition plates 101 are fixedly provided on both the front and rear sides of the body 1. An installation area 102 is formed between the partition plates 101 and the top of the body 1. Slide rails 4 are fixedly provided on both the left and right sides of the installation area 102. The slide rails 4 are distributed vertically. The upper and lower ends of the slide rails 4 are respectively fixedly connected to the top plate of the body 1 and the upper surface of the partition plates 101. The sides of the slide rails 4 are fixedly connected to the side frames of the body 1. The grille 2 is slidably connected between the two slide rails 4 along the height direction of the body 1. Among them, the shape of the front view projection of the slide rail 4 is in a shape of a "匚". The left and right sides of the grille 2 are respectively slid vertically between the two slide rails 4, so that when the grille 2 is in the installation area 102, it cannot move horizontally and can only move vertically.

[0027] A disassembly area 103 is formed between the partition plates 101 and the bottom of the body 1. The grille 2 can slide down from the installation area 102 into the disassembly area 103 to separate the grille 2 from the body 1. Among them, a through hole is vertically formed on the partition plates 101. The grille 2 can pass through the through hole to switch between the installation area 102 and the disassembly area 103. And, the length and height of the disassembly area 103 are not less than the length and height of the grille 2, so that when the grille 2 is completely located in the disassembly area 103, the grille 2 can be directly taken out from the disassembly area 103, thus completing the disassembly operation of the grille 2.

[0028] In this embodiment, the shape of the side projection of the grille 2 is in a shape of a "匚". The screen 3 is slidably engaged with the grille 2 along the length direction of the grille 2.

[0029] As Figure 4 shown, the shapes of the upper and lower ends of the side of the grille 2 are respectively in a shape of a "冂" and a shape of a "凵". The screen 3 is slidably inserted into the inside of the grille 2 along the length direction of the grille 2, so that the disassembly and assembly process of the grille 2 and the screen 3 is convenient and fast. And the length of the screen 3 is equal to the length of the grille 2, so that the sides of the grille 2 and the screen 3 are in a flush state.

[0030] Furthermore, two first clamping grooves 201 are formed on one side of the grille 2 away from the screen 3. The two first clamping grooves 201 are symmetrically distributed left and right. Two second clamping grooves 301 are formed on one side of the screen 3 away from the grille 2. The positions of the two second clamping grooves 301 respectively correspond to the positions of the two first clamping grooves 201. When the screen 3 is installed inside the grille 2, the first clamping grooves 201 are opposite to the second clamping grooves 301. A clamping component 5 is commonly connected in the first clamping grooves 201 and the second clamping grooves 301 on the same side. The clamping component 5 is used to fix the screen 3 inside the grille 2, so that the connection between the grille 2 and the screen 3 is more firm and stable.

[0031] Specifically, the clamping assembly 5 includes a U-shaped clamp 501, which comprises two clamping plates located in the first clamping groove 201 and the second clamping groove 301, respectively. The U-shaped clamp 501 is made of spring steel or other elastic and deformable metal material. The two clamping plates of the U-shaped clamp 501 are respectively fitted into the first clamping groove 201 and the second clamping groove 301 to clamp and fix the sides of the grid 2 and the screen 3, while preventing the U-shaped clamp 501 from moving vertically in the first clamping groove 201 and the second clamping groove 301.

[0032] A sliding plate 502 is fixedly mounted on the U-shaped clamp 501. The sliding plate 502 is magnetically connected to the sides of the grid 2 and the screen 3 via a magnetic plate 503. The magnetic plate 503 is fixedly connected to the side of the sliding plate 502 facing the grid 2 and the screen 3. The frames of the grid 2 and the screen 3 are made of carbon steel or other specific magnetic metal materials, so that the magnetic plate 503 can be magnetically attracted to the sides of the grid 2 and the screen 3, making the sides of the grid 2 and the screen 3 flush. This also prevents the U-shaped clamp 501 from moving horizontally, improving the stability of the grid 2 and the screen 3 after connection.

[0033] On the other hand, the slide plate 502 is vertically connected to the slide rail 4, such as... Figure 7 As shown, the slide plate 502 is located inside the slide rail 4. The front and rear side walls of the slide plate 502 are slidably connected to the inner side wall of the slide rail 4. The frictional resistance between the slide plate 502 and the inner side wall of the slide rail 4 is relatively large, so that when the grid 2 drives the slide plate 502 to slide on the slide rail 4, it can be in a slow and stable state, making the movement process more stable.

[0034] It should be noted that the slide rail 4 has a threaded hole 401, and the first clamping groove 201, the second clamping groove 301, and the U-shaped clamp 501 all have through holes. When the grid 2 is completely located within the partition plate 101, the threaded hole 401 and the through hole are positioned accordingly. This allows the user to screw bolts into the threaded hole 401 and the through hole when the grid 2 moves into the partition plate 101, thereby connecting and fixing the grid 2, screen 3, U-shaped clamp 501, and slide rail 4. The slide rail 4 is fixedly connected to the machine body 1. Therefore, the grid 2 and screen 3 can be fixedly installed on the machine body 1, making operation simple and convenient.

[0035] The working principle and usage process of this utility model are as follows: First, when installing the grid 2 and the screen 3, slide the screen 3 along the length of the grid 2 and embed it into the inner side of the grid 2. Clamp the U-shaped clamp 501 in the first clamping groove 201 and the second clamping groove 301 to complete the connection between the grid 2 and the screen 3, making it difficult for the grid 2 and the screen 3 to separate. Then, place the grid 2 into the disassembly area 103 and slide it vertically towards the partition 101, so that the grid 2 and the screen 3 pass through the partition 101 and enter the installation area 102 until the top of the grid 2 abuts against the top plate of the machine body 1. At this time, the through holes on the first clamping groove 201, the second clamping groove 301 and the U-shaped clamp 501 will be aligned with the threaded holes 401 on the slide rail 4. Another worker can then use bolts to fix the grid 2 and the screen 3 to the machine body 1 to complete the installation operation.

[0036] During disassembly, the bolts on the slide rail 4 are removed. The grille 2 and screen 3 will fall from the installation area 102 into the disassembly area 103 due to their own gravity. The frictional resistance between the slide plate 502 and the slide rail 4 is relatively large. Therefore, the falling process of the grille 2 and screen 3 is slow and stable. The staff can manually intervene in the falling speed of the grille 2. When the grille 2 has completely fallen into the disassembly area 103, the grille 2 can be taken out from the disassembly area 103 to complete the disassembly operation. Then the grille 2 and screen 3 are cleaned at the same time.
