Description

Technical Field

[0001] The utility model relates to the technical field of fresh air, and in particular to a ventilation structure of a fresh air system of an air conditioner. Background Art

[0002] The fresh air system can introduce fresh air from the outside into the room, realize the replacement of indoor and outdoor air, and discharge the turbid indoor air, which can improve the air quality in the room and keep the room fresh and comfortable. However, there is a filter plate in the fresh air system to filter the outdoor air. After long-term use, there is a lot of dust on the surface of the filter plate, which makes the filtering effect of the filter plate poor.

[0003] Patent document CN220169560U discloses a "ventilation structure of a public building indoor air conditioning fresh air system, including a central air conditioning indoor unit, an air inlet pipe is arranged at the lower part of the central air conditioning indoor unit, an air outlet pipe is arranged at the front side of the central air conditioning indoor unit, a heat exchange mechanism is connected to the air outlet pipe, an air inlet end of the heat exchange mechanism is connected to an air supply pipe 1, one end of the air supply pipe 1 is connected to a fresh air host, an air outlet end of the heat exchange mechanism is connected to an air supply pipe 2, the other end of the air supply pipe 2 is connected to a fresh air outlet, the fresh air outlet is arranged on the ceiling of the public building, the heat exchange mechanism is used to exchange heat between the cold air from the air conditioner and the external air, so that the external air reaches a temperature close to the air outlet temperature of the air conditioner, so that when the fresh air enters the room, there will be no obvious temperature difference, so that people feel more comfortable.";

[0004] When the above device is in use, when the fresh air system sends fresh air into the room through the air inlet pipe, it will first pass through the air outlet pipe of the air conditioner, and use the heat exchange mechanism to exchange heat between the cold air from the air conditioner and the external air, so that the external air reaches a temperature close to the air outlet temperature of the air conditioner. Although this device does not cause obvious temperature difference in the room, when this device is used in offices and other places, the fresh air will intercept harmful substances through the filter plate in the air conditioner before entering the room. The filter plate needs to be replaced after long-term use, and the filter plate requires the air conditioner to be disassembled, which makes replacement more troublesome, so it needs to be improved by the staff.

DETAILED DESCRIPTION

[0026] See also Figures 1 to 6 , a ventilation structure of an air conditioning fresh air system, comprising:

[0027] A filter box 1, the front and rear sides of the filter box 1 are fixedly connected with ventilation pipes 2, the front of the filter box 1 is slidably connected with a filter box 3, the left and right sides of the front of the filter box 3 are slidably connected with filter plates 4, the surface of the filter plate 4 is fixedly connected with a filter screen 5, the surface of the filter box 3 is fixedly connected with limiting rods 6 around the surface, and the surface of the limiting rods 6 is slidably connected to the inner wall of the filter box 1;

[0028] When the filter screen 5 needs to be replaced, the baffle 11 is pulled outward, so that the baffle 11 drives the filter box 3 at the back to move outward, so that the filter box 3 is separated from the filter box 1, and then the filter box 3 is separated from the baffle 11, and then the activated carbon and other purification substances in the filter box 3 are replaced, and then the filter plate 4 is pulled outward, so that the filter plate 4 drives the filter screen 5 in the middle to slide outward and separate from the filter box 3, and then the new filter plate 4 and the filter screen 5 are inserted into the filter box 3 by sliding, and then the filter box 3 and the baffle 11 are installed, and the device is inserted into the filter box 1 again, so as to complete the replacement of the filter screen 5;

[0029] Connecting rods 7 are inserted on both the left and right sides of the tail of the filter box 1, and the upper and lower sides of the connecting rod 7 are fixedly connected to limit blocks 8, and the front of the connecting rod 7 is fixedly connected to a soft pad 9;

[0030] When replacing the filter screen 5, the filter box 3 is pulled outward, so that the soft pad 9 rubs against the inner wall of the filter box 1, and the soft pad 9 collects dust and other impurities on the inner wall of the filter box 1 into the soft pad 9, and then the two groups of soft pads 9 are pulled outward, so that the soft pad 9 drives the connecting rod 7 to slide out of the filter box 3, and the connecting rod 7 drives the limit blocks 8 at the upper and lower ends to slide out and separate from the filter box 3;

[0031] A fixing block 10 is inserted in front of the filter box 3, a baffle 11 is fixedly connected in front of the fixing block 10, and a handle 12 is fixedly connected in front of the baffle 11;

[0032] When the filter screen 5 needs to be replaced, the handle 12 is held, so that the handle 12 drives the baffle 11 at the rear to be pulled outward, and the baffle 11 drives the fixing block 10 at the rear to pull out the filter box 3, and after the purification material such as activated carbon is placed in the filter box 3, the fixing block 10 is inserted into the filter box 3, so that the fixing block 10 blocks the filter box 3, so that the activated carbon is fixed to the inner wall of the filter box 3;

[0033] The upper and lower sides of the tail of the baffle 11 are fixedly connected with a plug-in board 13, the inner wall of the plug-in board 13 is connected with a spring 14, and one end of the spring 14 is connected with a limit buckle 15;

[0034] The limiting buckle 15 is in a triangular shape, and the hypotenuse faces the filter box 3, so that the plug-in board 13 only needs to be inserted into the filter box 3 and pushed, so that the filter box 3 squeezes the limiting buckle 15 and shrinks into the inner wall of the plug-in board 13. After being pushed to a specified position, the spring 14 pushes the limiting buckle 15, so that the limiting buckle 15 is inserted into the square hole of the filter box 3, thereby fixing the baffle 11 and the filter box 3;

[0035] A connecting ring 16 is fixedly connected to the front of the top of the filter box 1, and a connecting rod 17 is inserted into the inner wall of the connecting ring 16. A connecting block 18 is fixedly connected to the tail end of the connecting rod 17, and the bottom of the connecting block 18 is fixedly connected to the top of the baffle 11. The tail end of the connecting rod 17 is rotatably connected to a magnet 19;

[0036] When the filter 5 needs to be replaced, rotate the magnet 19 to disengage the magnet 19 from the filter box 1, then hold the handle 12 and pull it outward to disengage the connecting rod 17 and the magnet 19 from the connecting ring 16. After replacing the filter 5, insert the filter box 3 into the filter box 1, rotate the magnet 19 again to make the magnet 19 perpendicular to the connecting rod 17, and then push the filter box 3 to make the magnet 19 and the connecting rod 17 pass through the connecting ring 16, and then rotate the magnet 19 to make the magnet 19 contact the filter box 1 and magnetically attract, thereby fixing the baffle 11 and the filter box 1.

[0037] Working principle: rotate the magnet 19 to disengage from the filter box 1, then hold the handle 12, and then pull the handle 12 outward to disengage the filter box 3 from the filter box 1. At the same time, the cushion 9 slides over the inner wall of the filter box 1, thereby pushing out the garbage on the inner wall of the filter box 1. At this time, the filter screen 5 is exposed to the outside, press the limit buckle 15, so that the limit buckle 15 shrinks into the inner wall of the plug-in board 13, and then hold the handle 12 and pull it outward so that the plug-in board 13 can be pulled out of the filter box 3, and the fixed block 10 is separated from the filter box 3, and then the filter plate 4 is pulled outward to disengage the filter plate 4 and the filter screen 5 from the filter box 3, and then a new filter plate 4 and filter screen 5 are inserted into the filter box 3, the cushion 9 is pulled out of the filter box 3, and the new cushion 9 is replaced, thereby completing the replacement of the filter screen 5.
