Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner indoor units, in particular to a wall-mounted air conditioner indoor unit which is convenient for disassembling and assembling an oil and gas filter. Background Art

[0002] Air conditioning, also known as air conditioners, refers to equipment that uses artificial means to adjust and control parameters such as temperature, humidity, and flow rate of ambient air in buildings or structures. Air conditioning is an indispensable part of modern life. In hotel lobbies, private rooms, and especially hot pot restaurants, when diners are dining, the steam emitted from hot food contains a large number of oil molecules and water molecules floating in the air and being sucked in by the circulating air conditioner. When the water molecules are cooled, they will be condensed into condensed water and discharged. When the oil molecules encounter objects with a temperature lower than that of the oil molecules, they will be quickly adsorbed and condensed with dust in the air to form hard putty, which will cover the heat exchanger and form a blockage. At this time, the air output of the air conditioner is reduced, bacteria will be deposited, odor will be generated, the air conditioner efficiency will be reduced, energy consumption will increase, and the life of the air conditioner will be shortened. Therefore, the air conditioners used in restaurants and hot pot restaurants will be installed with multiple layers of overlapping interactive filters on the air inlet side of the air conditioner. When they encounter a metal filter with a temperature lower than that of oil and gas, they will be adsorbed, and the dust in the air will also be adsorbed, which can ensure that the air conditioner fins are not clogged with oil.

[0003] Existing oil and gas filters are usually multi-layered, and the oil and gas are adsorbed and filtered through the multi-layer filter holes. After the oil and gas filter is used for a certain period of time, it needs to be disassembled and cleaned, for example (attached to the instruction manual Figure 1 As shown in the figure, multiple layers of oil and gas filters are fixed in a single filter frame, and the filter frame is fixed by screws and pressing plates, so that the disassembly and assembly of the filter frame requires professional tools, which is relatively cumbersome, and when cleaning, the multiple layers of filters in the filter frame need to be removed and installed one by one, which greatly reduces the cleaning efficiency.

DETAILED DESCRIPTION

[0023] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings.

[0025] Reference Figure 2-6 A wall-mounted air conditioner indoor unit for easy disassembly and assembly of an oil and gas filter comprises an air conditioner indoor unit body 1, a mounting frame 2 is fixedly connected to the upper surface of the air conditioner indoor unit body 1, movable grooves 3 are symmetrically distributed on both side surfaces of the mounting frame 2, a through groove 4 is opened on the inner bottom wall of the mounting frame 2, a guide rod 5 is fixedly connected to the inner bottom wall of the mounting frame 2, four guide rods 5 are symmetrically distributed in groups of two, and a top plate 6 is movably sleeved on the outer surface of each group of guide rods 5;

[0026] A convenient disassembly and assembly device is disposed on the lower surface of the top plate 6 , and the convenient disassembly and assembly device includes a first support spring 7 , one end of the first support spring 7 is fixedly connected to the lower surface of the top plate 6 .

[0027] The other ends of the two first support springs 7 are fixedly connected to the inner bottom wall of the installation frame 2, and the outer surfaces of the multiple guide rods 5 are movably sleeved with filter frames 71 distributed in a linear array. Through the supporting elastic force of the first support springs 7, the multiple filter frames 71 are made to contact each other to form an overall multi-layer staggered filtration. Two adjacent filter frames 71 are in contact with each other, and the outer surfaces of the multiple filter frames 71 are movably sleeved with the inner wall of the installation frame 2. The inner wall of the filter frame 71 is fixedly sleeved with a porous filter 72. The adjacent two porous filter frames The filter holes of the net 72 are staggered to improve the adsorption performance of oil and gas. The porous filter screen 72 can be made of aluminum material, and its lower thermal conductivity can better adsorb oil and gas. The two side surfaces of one filter frame 71 are fixedly connected with symmetrically distributed lifting blocks 73. One end of the lifting block 73 passes through the movable groove 3 and extends to one side surface of the installation frame 2. The upper end inner wall of the movable groove 3 is provided with an inclined extrusion port 74, and the two side surfaces of the other installation frame 2 are provided with symmetrically distributed limiting sliding grooves 75.

[0028] The inner wall of the limiting slide groove 75 is slidably sleeved with a symmetrically distributed limiting slider 76, and the opposite surfaces of the two limiting sliders 76 are fixedly connected with a second supporting spring 77. The restoring elastic force of the second supporting spring 77 drives the two limiting sliders 76 to move away from each other. A driving rod 78 is fixedly connected to the surface of one side of the limiting slider 76, and the inner walls on both sides of the movable groove 3 are provided with symmetrically distributed limiting grooves 79. The driving rod 78 is plugged into the limiting groove 79 to play a limiting installation role, and the outer surface of the driving rod 78 is slidably plugged into the inner wall of the limiting groove 79.

[0029] By providing a convenient disassembly and assembly device, multiple filter frames 71 can be stacked into a whole when in use, and multi-layer porous staggered filtration can be performed. No professional tools are required during disassembly and assembly, and the operation is convenient. Moreover, by stacking and using multiple filter frames 71, it is easy to disassemble and clean them during cleaning, thereby improving the cleaning efficiency.

[0030] Working principle: Step 1, multiple filter frames 71 are stacked and installed, so that the air conditioner indoor unit body 1 can perform porous staggered filtering on the oil and gas when the air is taken in. When disassembling and cleaning, the two driving rods 78 are moved relative to each other. The movement of the driving rod 78 causes the two limiting sliding blocks 76 to move relative to each other through the cooperation of the limiting sliding groove 75, thereby driving the second supporting spring 77 to contract. When the driving rod 78 moves out of the limiting groove 79, the top plate 6 is guided by the guide rod 5 through the restoring elastic force of the first supporting spring 7, and drives the multiple filter frames 71 to move upward. At this time, hold the lifting blocks 73 on both sides of the bottom filter frame 71 to lift it up, so that the multiple filter frames 71 can be taken out, and the filter frames 71 after being taken out are separated from each other, so as to facilitate the cleaning of the adsorbed oil and gas.

[0031] Step 2: During installation, the filter frame 71 is placed in the installation frame 2 through the cooperation of the guide rod 5, and the filter frame 71 with the lifting block 73 is placed at the bottom so that its lower end contacts the top plate 6, and then other filter frames 71 are stacked on top. At this time, the top plate 6 is squeezed to drive the first support spring 7 to contract, and finally the filter frame 71 driving the drive rod 78 is installed. During installation, the drive rod 78 contacts the inclined surface extrusion port 74, and the two drive rods 78 are squeezed by the inclined surface to pass through The limiting slider 76 cooperates with the relative movement, and its second supporting spring 77 contracts, so that its driving rod 78 moves into the movable groove 3. When it moves to the limiting groove 79, the elastic force of the second supporting spring 77 drives the limiting slider 76 to reset and move. The movement of the limiting slider 76 causes its driving rod 78 to slide into the limiting groove 79 for limiting, thereby completing the installation of the filter frame 71, and through the reset elastic force of the first supporting spring 7 and cooperating with the top plate 6, the multiple filter frames 71 are tightly fitted for filtering operations.
