Description

Technical Field

[0001] This utility model relates to the field of central air conditioning technology, specifically to a central air conditioning air supply device with a sealing function. Background Technology

[0002] A central air conditioning system consists of one or more cold and heat source systems and multiple air conditioning systems. Unlike traditional refrigerant-based air conditioners (such as single-unit air conditioners or VRV systems), which centrally process air to achieve comfort requirements, this system uses the principle of liquid vaporization refrigeration to provide the required cooling capacity to the air conditioning system to offset the heat load of the indoor environment. The heating system provides the required heat to the air conditioning system to offset the heating and cooling load of the indoor environment.

[0003] For example, CN222210588U discloses a central air conditioning air filtration and supply device, including a device body. The device body includes a filter box, an air supply frame, an air inlet frame, and a filter element. The air supply frame is installed at the front end of the filter box, the air inlet frame is installed at the rear end of the filter box, and the filter element is installed inside the filter box. The filter element includes a filter base plate, horizontal filter plates, and filter blocks. A set of horizontal filter plates is installed at the front and rear ends of the top of the filter base plate, and several sets of filter blocks are installed horizontally at equal intervals on the top of the filter base plate. The filter blocks have a triangular structure. Several sets of flow holes and adsorption lint are provided on the surfaces of both the filter blocks and the horizontal filter plates. The filter base plate, horizontal filter plates, and filter blocks are all made of non-woven fabric. This device can effectively filter the air supplied by the central air conditioning system, thereby improving the purity of the exhaust gas.

[0004] However, in implementing the relevant technology, the above-mentioned central air conditioning air supply device has the following problems: it is difficult to seal the exhaust hood of the air supply duct, which results in the air supply duct not being able to be sealed and isolated, leading to cross-contamination of gases, difficulty in protecting the air conditioning system, difficulty in saving energy and controlling odors, and causing dirty air to flow back in and pollute the indoor environment. Therefore, a central air conditioning air supply device with a sealing function is proposed. Utility Model Content

[0005] This utility model proposes a central air conditioning air supply device with a sealing function, which solves the problem in related technologies that it is difficult to seal the exhaust cover of the air supply duct, resulting in the air supply duct not being able to be sealed and isolated, leading to cross-contamination of gases, difficulty in protecting the air conditioning system, difficulty in saving energy and controlling odors, and causing dirty air to flow back in and pollute the indoor environment.

[0007] An exhaust hood is installed at the bottom of the air supply duct;

[0008] A sealing mechanism is provided on the inner bottom wall of the air supply duct to seal the exhaust hood;

[0009] A filtration mechanism is installed on one side of the air supply duct and is used to filter the air discharged from the central air conditioning system.

[0010] An installation mechanism is provided on the outer wall of the air supply duct for fixing the air supply duct to the wall top.

[0011] The sealing mechanism includes two slide rails that are slidably connected to the bottom wall of the air supply duct, two sealing plates that are slidably connected to the two slide rails, push rods that are rotatably connected to the top of the two sealing plates, a motor that is fixedly installed on the top wall of the air supply duct, and a turntable that is fixedly connected to the output end of the motor. The turntable is rotatably connected to the end of the push rod away from the sealing plate.

[0012] Preferably, the filtration mechanism includes a drawer slot formed on one side of the air supply duct and a drawer frame slidably connected inside the drawer slot.

[0013] Preferably, the interior of the drawer frame is fixedly installed with filter cotton, activated carbon filter and gauze from left to right.

[0014] Preferably, a retaining plate is rotatably connected to one side of the air supply pipe, the retaining plate is located on one side of the draw slot, and a slot plate is fixedly installed on one side of the air supply pipe, the slot plate is located on the other side of the draw slot, and the retaining plate and the slot plate are engaged with each other.

[0015] Preferably, the installation mechanism includes two screws disposed on both sides of the air supply pipe, two support plates sleeved on the two screws, and two nuts threadedly connected to the two screws. The two support plates are located on the upper and lower sides of the air supply pipe.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] The motor drives the turntable to rotate, and the linkage push rods rotate and hinge on the turntable. The two sealing plates slide together on the two slide rails to seal the top of the exhaust hood. This effectively seals the exhaust hood of the air supply duct when the central air conditioning is turned off, thus sealing and isolating it, preventing cross-contamination, protecting the air conditioning system, saving energy, controlling odors, and effectively preventing dirty air from flowing back in and polluting the indoor environment.
