Description

Technical Field

[0001] The invention belongs to the technical field of central air conditioners, and in particular relates to an energy-saving central air conditioner fresh air filtering device. Background Art

[0002] Central air conditioning is an independent miniaturized air conditioning system, which consists of one or more cold and heat source systems and multiple air conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system to offset the heat load of the indoor environment; at the same time, the heating system provides the required heat for the air conditioning system to offset the cooling and heating loads of the indoor environment.

[0003] When the central air conditioner is in operation, fresh air needs to be introduced into the room from the outside. After the fresh air is sucked into the fresh air duct, the fresh air needs to be filtered, and dust and impurities are filtered through the filter plate. However, after the central air conditioner has been running for a long time, a large amount of dust and impurities will be attached to the side of the filter plate facing the fresh air outlet, which not only affects the filtering effect of the fresh air, but also affects the air intake volume. Although the existing filtering device can perform the filtering function, the operator needs to disassemble the fresh air duct every once in a while, and then take out the filter plate for cleaning. In addition, since the fresh air duct is generally installed on the ceiling, it is very troublesome to clean the filter, so it needs to be improved. Summary of the invention

[0017] 3. The present invention provides a sealing plate, a rotating plate, a pull rod and a clamping block. When the filter plate body needs to be replaced after being used for a long time, the operator pulls the pull rod outward, so that the pull rod drives the clamping block to move outward, thereby making the clamping block disengage from the contact with the rotating plate, thereby releasing the fixing effect on the rotating plate. Then the operator rotates the rotating plate, so that the rotating plate disengages from the contact with the sealing plate, thereby releasing the fixing of the sealing plate. At this time, the operator can pull the handle outward, so that the sealing plate drives the mounting frame to move outward, thereby making the filter plate body disengage from the interior of the fresh air duct, thereby replacing the filter plate body.

[0045] Working principle and usage process:

[0046] When the device is running, the operator starts the second motor 15 to make the round shaft 16 drive the baffle 17 to rotate, so that the baffle 17 fits the top of the inner surface of the fresh air duct 1, thereby releasing the blockage of the fresh air duct 1, and the fresh air will enter from the rear end of the fresh air duct 1, and continue to be transported forward after being filtered by the filter plate body 3. When the operator needs to clean the filter plate body 3, first start the second motor 15 to make the round shaft 16 drive the baffle 17 to rotate, and then make the baffle 17 contact the rubber pad 18, so as to The interior of the fresh air duct 1 is blocked, and then the fan 11 is started, so that the air inlet pipe 12 sucks in the outside air, and then passes through the air outlet pipe 13 and the connecting hose 14, and finally blows the air from the air guide box 6 to the filter plate body 3, and then by starting the first motor 7, the rotating shaft 8 drives the rotating rod 9 to rotate, so that the hinged rod 10 can pull the air guide box 6 to move upward under the limiting action of the vertical rod 4, and then the air guide box 6 can comprehensively back-blow and clean the filter plate body 3, thereby facilitating the operator to clean the filter plate body 3.

[0047] The dust blown back will be blocked by the baffle 17 and then gradually fall into the dust bag 25. At this time, the operator can push the pressure plate 24 upward to release the pressure on the dust bag 25, and then remove the dust bag 25 to clean the dust inside the dust bag 25.

[0048] When the operator needs to replace or repair the filter plate body 3, he first pulls the pull rod 33 outward to move the block 34 toward the inside of the installation box 32, thereby releasing the fixing effect on the rotating plate 30, and then rotates the rotating plate 30 around the fixed shaft 29 to make the rotating plate 30 disengage from the inside of the L-shaped plate 31 and disengage from the sealing plate 27. At this time, the fixing of the sealing plate 27 will be released, and then the operator can pull the handle 28 outward to drive the installation frame 2 to move outward, and then remove the filter plate body 3 from the inside of the fresh air duct 1, thereby facilitating the replacement or repair of the filter plate body 3.
