Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning air outlet devices, and in particular to a displacement air supply device for air-conditioning equipment with uniform air outlet. Background Art

[0002] Air conditioning, also known as air conditioners, refers to equipment that manually adjusts and controls parameters such as temperature, humidity, cleanliness, and flow rate of the ambient air within a building or structure. Most air conditioners utilize a compressor to cause the refrigerant to evaporate or condense, which in turn triggers the evaporation or condensation of the surrounding air to achieve the desired temperature and humidity.

[0003] It mainly includes the air-conditioning outdoor unit, the air-conditioning main unit and connecting pipes. The air-conditioning main unit is used for cooling or heating and for spraying cold and hot air. Now many health-tech residences have set the fresh air system as the standard configuration of the building, especially in the northern region. The outdoor air quality is very poor, and a replacement fresh air system must be provided to provide fresh air for the indoor room.

[0004] The air outlets of wall-mounted air conditioners and central air conditioners in the existing technology are all installed on the upper part of the human body, that is, the air is discharged from the top. However, in the top air supply mode, the fresh air and polluted air of the fresh air system are both completed through the air outlets located on the ceiling. The polluted air has a higher density and is located below the room. The fresh air has a lower density and is located above. If it is top supply and top return, the fresh air coming in is more easily discharged, while the air below is not necessarily discharged quickly and effectively. Secondly, the existing air outlet of the air conditioner directly supplies air and only has the function of adjusting the air outlet direction, and the air outlet is not uniform. Summary of the Invention

[0005] Based on the technical problems of existing air conditioners with top air supply, poor fresh air replacement performance and uneven air output, the present invention proposes a replacement air supply device with uniform air output for air conditioning equipment.

[0006] The present invention provides a displacement air supply device for air conditioning equipment with uniform air output, comprising an air inlet box, an air conditioner main unit connected to the air inlet box outlet via a duct, an underground air outlet box connected to the air conditioner main unit outlet via a square tube, and an exhaust box installed on the upper inner wall of a house.

[0007] A self-cleaning filter mechanism and an adsorption and desorption box are provided at the lower part of the air inlet box. The self-cleaning filter mechanism includes a filter screen arranged obliquely downward, guide rails fixed on the outer walls of both sides of the filter screen, and a sliding brush slidably mounted on the guide rails. An electric push rod is provided on the filter screen, and the electric push rod is connected to the sliding brush.

[0008] The air outlet box includes a square groove, an air equalization mechanism, an alloy panel, an air equalization cover, a curved air permeable plate and an air adjustment mechanism, and the air equalization mechanism includes an air gathering plate welded to the inner wall of the square groove, the air gathering plate is a "V"-shaped structure, and the air gathering plate is provided with air holes distributed at equal distances. The outer wall of the air gathering plate is connected to curved plates distributed at equal distances, and a curved air duct with an "S"-shaped structure is formed between the curved plates. The top of the curved air duct is connected to the air equalization cover by screws, and an arc-shaped air permeable plate is fixed to the inner wall of the curved air duct.

[0009] Preferably, a partition is welded to the inner wall of the air inlet box in the horizontal direction, and the partition separates the air inlet box into an air outlet chamber and a filter chamber located below the air outlet chamber. An ash outlet trough is provided on the bottom inner wall of the air inlet box.

[0010] Preferably, the air distribution cover plate is located directly above the arc-shaped air permeable plate, and the air distribution cover plate is provided with first air holes distributed at equal distances, and the arc-shaped air permeable plate is provided with second air holes distributed at equal distances, and the first air holes and the second air holes are staggered.

[0011] Preferably, an installation opening is opened on the outer wall of one side of the filter chamber, an air intake fan is installed in the installation opening through a bracket, and an adsorption and desorption box is installed on the inner wall of the filter chamber away from the air intake fan. An inspection opening is opened on the outer wall of one side of the filter chamber, and a box door is hinged on the inner wall of the inspection opening.

[0012] Preferably, an air outlet is provided on the outer wall of one side of the air outlet chamber, and a rainproof pipe is connected to the inner wall of the air outlet, and the outer wall of the other side of the air outlet chamber is connected to the interior of the exhaust box through a conveying pipe.

[0013] Preferably, the exhaust box has exhaust grooves distributed at equal distances on its outer wall on a side away from the delivery pipe, and a dustproof net is bonded to the inner wall of the exhaust groove.

[0014] Preferably, the air regulating mechanism comprises a grid plate welded to the outer wall of the alloy panel on one side close to the square groove, and the grid plate is provided with air outlet slots distributed at equal distances.

[0015] Preferably, the inner wall of one end of the air outlet slot is rotatably connected to a rotating shaft, the rotating shaft is connected to a flexible sealing plate, and the inner wall of the other end of the air outlet slot is fixed with a micro motor through a motor mounting frame, and the output shaft of the micro motor is connected to the flexible sealing plate.

[0018] The beneficial effects of the present invention are:

[0019] 1. The "V"-shaped wind gathering plate can gather wind, accelerate the air flow speed, and make the wind quickly spread across the entire square slot. The outer wall of the wind gathering plate is connected with equally distributed curved plates, forming an "S"-shaped curved air duct between the curved plates. The "S"-shaped curved air duct can extend the residence time of the wind in the air outlet box, avoiding direct air discharge. The reserved time is for the wind to be fully and evenly distributed throughout the square slot. Secondly, the air holes staggered on the arc-shaped air permeable plate and the air distribution cover further evenly distribute the air, thereby avoiding uneven air discharge from the air conditioner.

[0020] 2. Rainwater entering the filter chamber can flow out through the water outlet to avoid rainwater accumulation. Impurities in the incoming air are filtered through the filter, and the electric push rod drives the sliding brush to clean the filter. At the same time, the activated carbon set in the adsorption and desorption box dries and adsorbs the air. By heating the activated carbon, odorous gases and moisture are desorbed and precipitated, thereby extending the service life of the filter and activated carbon and facilitating maintenance and use.

[0021] 3. The exhaust box is set at the upper part of the roof, which is equivalent to the upper part of the human head. The air outlet box is set at the bottom and can be pre-buried in the wooden floor. Therefore, when the air is discharged, the fresh air blows upward from the bottom, which can blow the turbid air into the upper part of the house, which is conducive to replacing and exhausting the turbid air.
