[0002] In modern industrial production environments, the temperature and air quality inside the factory have an important impact on the production process and the working comfort of employees. In order to ensure the normal operation of production equipment and that employees can work in a suitable environment, the application of industrial air conditioning has become extremely common.

[0003] During the industrial production process, a large amount of heat and oil stains are often generated. These oil stains mixed into the air will not only affect the air quality, but may also cause damage to the air-conditioning equipment itself. Therefore, during the use of industrial ceiling air conditioners, the demand for installing oil filtering mechanisms to filter oil stains in the air is increasing.

[0004] However, since most industrial ceiling air conditioners are installed at high positions, there are risks in replacing the oil filter mechanism. There is a lack of a quick mechanism to fix the oil filter, making it convenient to quickly remove and install the oil filter mechanism.

The evaporator 8 is located just in front of the air outlet end of the fan 7. An air outlet 9 is arranged in the front end side wall of the body 1, and two groups of air outlets 9 are arranged, and the two groups of air outlets 9 are located just in front of the evaporator 8. It is worth noting that other components that enable the air conditioner indoor unit to work are also arranged on the inner side of the body 1. Since they are existing equipment of the prior art and are not within the protection scope of this application, they are not described here and are not shown in the figure.

[0024] In one embodiment of the present invention, a filter assembly 10 is provided inside the body 1, and the filter assembly 10 includes a mounting groove 101. The mounting groove 101 is fixedly installed on the top of one side of the body 1 close to the filter plate 4, and a rectangular cover 102 is slidably installed inside the mounting groove 101. In addition, two groups of mounting grooves 101 are provided, so that the rectangular cover 102 can move more stably. A U-shaped cover 103 is clamped on the top of the rectangular cover 102, and vertical plates 104 are slidably fitted at both ends of the inside of the rectangular cover 102. Two groups of vertical plates 104 are provided, and an oil filter 105 is fixedly installed between the two groups of vertical plates 104. The oil filter 105 is made of oil-absorbing cotton material. In addition, the oil filter 105 is arranged in a Z-shaped array as a whole, so that the oil filtration can be increased compared with a single plane. The interception area of ​​the net 105 can better intercept the oil stains in the air, so that the oil stains flow to the bottom of the inner part of the rectangular cover 102 through the gap between the Z-shapes. Fixed blocks 106 are fixedly installed at both ends of the inner bottom of the rectangular cover 102, and a triangular inclined block 107 is fixedly installed at the center of the upper surface of the inner bottom of the rectangular cover 102. A card slot 1001 and a circular groove 1002 are respectively opened in the center of the inner part of the fixed block 106 from top to bottom. A card block 1003 and a round rod 1004 are respectively fixedly installed in the center of the bottom of the vertical plate 104 from top to bottom. The round rod 1004 fits the inner side of the circular groove 1002. First, the vertical plate 104 and the oil filter net 105 are placed in the inner side of the rectangular cover 102 as a whole. At this time, the card block 1003 will be located inside the card slot 1001, and the round rod 1004 will fit inside. Inside the circular groove 1002, an active rack 1005 is fixedly installed on the outside of the block 1003, and a spring rod 1006 fixedly installed on the inner wall of the fixed block 106 is arranged on the inside of the groove 1001. The outside of the spring rod 1006 is fixedly connected to the center of the outer wall of one end of the V-shaped rod 1007, and the other end of the V-shaped rod 1007 is fixedly connected to the center of the outer wall of the driven rack 1008. The active rack 1005 meshes with the driven rack 1008, and a connecting rod 1009 is fixedly installed at the bottom of the spring rod 1006. When the block 1003 continues to move downward, it will drive the active rack 1005 to move synchronously and squeeze the driven rack 1008, so as to cooperate with the V-shaped rod 1007 to make the spring rod 1006 more evenly stressed, so that the spring rod 1006 can intermittently deform and recover synchronously. A sliding rod 1010 is fixedly installed on the side wall of the connecting rod 1009, and a sliding groove 1011 is opened on the inner side of the fixed block 106. The sliding rod 1010 slides and fits in the inner side of the sliding groove 1011. A roller 1012 is rotatably installed at the bottom of the connecting rod 1009, and the outer side of the roller 1012 rolls and fits in the inner side of the fixed block 106. At the same time, the movement of the connecting rod 1009 makes the sliding rod 1010 move inside the sliding groove 1011, and the connecting rod 1009 drives the roller 1012 to move synchronously. Therefore, when the bottom of the vertical plate 104 fits the top of the fixed block 106, the active rack 1005 and the driven rack 1008 finally reach a meshing state and no longer move, thereby making the vertical plate 104 more stable, and then the oil filter 105 is installed more firmly. When the U-shaped cover 103 is buckled,The rectangular cover 102 is slidably installed inside the installation groove 101. After the fan 7 is started, the air outside the air conditioner will flow to the oil filter 105, so that the oil filter 105 can better intercept the oil stains in the air. In addition, the fixed block 106, the slot 1001, the round slot 1002, the block 1003 and the round rod 1004 are provided in two groups, and the active rack 1005, the spring rod 1006, the V-shaped rod 1007, the driven rack 1008, the connecting rod 1009, the sliding rod 1010, the sliding groove 1011 and the roller 1012 outside the single group of blocks 1003 are provided in two groups, so that the vertical plate 104 is more stable.

[0025] In one embodiment of the present invention, a limiting component 11 is provided on the top of the top cover 2, and the limiting component 11 includes a fixed column 111, a fixed column 111 is fixedly installed on the top of the top cover 2, a threaded rod 112 is fixedly installed on the top of the fixed column 111, a limiting plate 113 is sleeved on the outer side of the fixed column 111, and a limiting groove 114 is provided inside the limiting plate 113, and the fixed column 111 slides and fits inside the limiting groove 114. Further, when the limiting plate 113 is moved through the limiting groove 114 on the outer side of the fixed column 111, a threaded knob 115 is threadedly installed on the outer side of the threaded rod 112, and the height of the limiting plate 113 is the same as the inner wall height of the U-shaped cover 103. The two are matched in size. When one end of the limit plate 113 moves to the inner side of the U-shaped cover 103, the threaded knob 115 on the outer side of the threaded rod 112 is tightened to fix the other end of the limit plate 113, thereby fixing the U-shaped cover 103. Conversely, when one end of the limit plate 113 completely leaves the inner side of the U-shaped cover 103, the threaded knob 115 is loosened to facilitate the removal of the U-shaped cover 103, and then to facilitate the fixation and quick removal of the oil filter 105. In addition, the fixing column 111, the threaded rod 112, the limit plate 113, the limit groove 114 and the threaded knob 115 are provided in two groups, so that the fixing effect of the U-shaped cover 103 is better.

[0026] In one embodiment of the present invention, a collecting assembly 12 is provided on the outside of the oil filter 105, and the collecting assembly 12 includes an opening 121, and a through opening 121 is provided on both sides of the bottom end of the rectangular cover 102, and a conical cover 122 is fixedly installed on both sides of the lower surface of the bottom end of the rectangular cover 102, and a through hole 123 is provided on the base frame 3, and the conical cover 122 penetrates the through hole 123, and the center of the cross section of the opening 121, the conical cover 122 and the through hole 123 is coaxial, and the bottom of the base frame 3 fits the top of the collecting box 124, and the collecting box 124 is sleeved on the inner side of the bottom end of the body 1, and the collecting box 124 is located directly below the conical cover 122. In addition, further, after the oil stains drip onto the triangular inclined surface block 107, they will be discharged from the outer wall of the inclined surface. The oil flows toward the opening 121 and enters the interior of the conical cover 122. The conical cover 122 allows the oil to flow more concentratedly toward the interior of the collection box 124. A handle 125 is fixedly installed at the bottom center of the collection box 124, a rotating rod 126 is fixedly installed at the bottom of the body 1, and a stop block 127 is rotatably installed on the outer side of the rotating rod 126 (it is worth noting that the rotational connection between the two has a damping feeling and fits tightly, thereby preventing the stop block 127 from shaking). The top of the stop block 127 slides and fits the bottom of the collection box 124. When the oil needs to be processed, the stop block 127 on the outer side of the rotating rod 126 is rotated to move the stop block 127 away from the bottom of the collection box 124 to release the fixation of the collection box 124. When the handle 125 is pulled, the collection box 124 is conveniently taken out.

[0027] In one embodiment of the present invention, an auxiliary component 13 is provided inside the body 1, and the auxiliary component 13 includes a U-shaped frame 131, and the U-shaped frame 131 is fixedly installed on the top of the bottom frame 3, and the U-shaped frame 131 is located between the partition 6 and the mounting groove 101. A servo motor 132 is fixedly installed on the outside of the U-shaped frame 131, and a rotating shaft 133 is fixedly installed on the output end of the servo motor 132. The rotating shaft 133 is rotatably installed on the inside of the top of the U-shaped frame 131, and the outside of the rotating shaft 133 is fixedly connected to the rectangular The U-shaped frame 134 has a heating wire 135 disposed inside the rectangular frame 134, and a power supply 136 is fixedly mounted on the outer wall of the rectangular frame 134. Further, when the air conditioner indoor unit is not in use, the servo motor 132 on the U-shaped frame 131 is started, so that the rotating shaft 133 drives the rectangular frame 134 and the heating wire 135 to rotate, and the power supply 136 is electrically connected to the heating wire 135 through a wire 137, and a temperature sensor 138 is disposed on the wire 137. The other end of the rectangular frame 134 is fixed. An auxiliary strip 139 is installed. When the power supply 136 is started, the electric heating wire 135 can be heated in cooperation with the wire 137 and the temperature sensor 138, and overheating can be prevented, so that a hot air flow can be blown to the oil filter 105. The interception and guidance of the auxiliary strip 139 can make the air supply effect better, so that the oil stains attached to the oil filter 105 are not easy to condense, and after being heated, they can flow better to the collection box 124 of the collection component 12, so as to avoid excessive accumulation of oil stains on the oil filter 105 and affect the interception and filtration effect, thereby improving the oil stain interception and filtration effect of the filter component 10. In addition, the rectangular frame 134, the electric heating wire 135, the power supply 136, the wire 137, the temperature sensor 138 and the auxiliary strip 139 are arranged in three groups, and the three groups of rectangular frames 134, the electric heating wire 135, the power supply 136, the wire 137, the temperature sensor 138 and the auxiliary strip 139 are all arranged in a circular array with equal spacing with the center of the circular cross section of the rotating shaft 133 as the center of the array.

[0028] Among them, the electrical components appearing in this application document are all electrically connected to the controller 5 and the 220V AC power supply, and the controller 5 is a conventional known device that can control the fan 7, evaporator 8, servo motor 132, heating wire 135, power supply 136, wire 137 and temperature sensor 138. The standard parts used in this application document can all be purchased from the market. The specific connection method of each part is connected by conventional means such as mature rivets and welding in the prior art, and the machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts the conventional connection method in the prior art, and no specific description is given here.

[0029] Working principle: First, put the vertical plate 104 and the oil filter 105 into the inner side of the rectangular cover 102 as a whole. At this time, the block 1003 will be located inside the slot 1001, and the round rod 1004 will fit inside the round slot 1002. When the block 1003 continues to move downward, it will drive the active rack 1005 to move synchronously and squeeze the driven rack 1008, so as to cooperate with the V-shaped rod 1007 to make the spring rod 1006 more evenly stressed, so that the spring rod 1006 can be deformed and restored synchronously and intermittently. At the same time, the movement of the connecting rod 1009 makes the sliding rod 1010 move in the sliding slot 101 1, the connecting rod 1009 synchronously drives the roller 1012 to move, so that when the bottom of the vertical plate 104 is attached to the top of the fixing block 106, the active rack 1005 and the driven rack 1008 finally reach a meshing state and no longer move, so that the vertical plate 104 is more stable, and then the oil filter 105 is installed more firmly. When the U-shaped cover 103 is buckled, the rectangular cover 102 is slidably installed into the installation groove 101, and the fan 7 is started, the air outside the air conditioner will flow to the oil filter 105, so that the oil filter 105 can better intercept the oil stains in the air.

[0030] Furthermore, when the limiting plate 113 is moved through the limiting groove 114 on the outside of the fixing column 111, when one end of the limiting plate 113 moves to the inside of the U-shaped cover 103, the threaded knob 115 on the outside of the threaded rod 112 is tightened to fix the other end of the limiting plate 113, thereby fixing the U-shaped cover 103. Conversely, when one end of the limiting plate 113 completely leaves the inside of the U-shaped cover 103, the threaded knob 115 is loosened to facilitate the removal of the U-shaped cover 103, and then facilitate the fixation and quick removal of the oil filter 105.

[0031] Furthermore, after the oil stains drip onto the triangular inclined block 107, they will flow from the outer wall of the inclined surface to the opening 121 and enter the interior of the conical cover 122. The conical cover 122 allows the oil stains to flow more concentratedly to the interior of the collection box 124. When the oil stains need to be dealt with, the block 127 on the outside of the rotating rod 126 is rotated to move the block 127 away from the bottom of the collection box 124, thereby releasing the fixation of the collection box 124. When the handle 125 is pulled, the collection box 124 can be easily taken out.

[0032] Furthermore, when the indoor unit of the air conditioner is not in use, the servo motor 132 on the U-shaped frame 131 is started, so that the rotating shaft 133 drives the rectangular frame 134 and the heating wire 135 to rotate. When the power supply 136 is started, the heating wire 135 can be heated in cooperation with the wire 137 and the temperature sensor 138 to prevent overheating, so that a hot air flow can be blown to the oil filter 105, and the interception and guidance of the auxiliary strip 139 can make the air supply effect better, so that the oil stains attached to the oil filter 105 are not easy to condense, and after being heated, they can flow better to the collection box 124 of the collection component 12, so as to avoid excessive accumulation of oil stains on the oil filter 105 and affect the interception and filtration effect, thereby improving the oil stain interception and filtration effect of the filter component 10.

[0033] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
