Description

Technical Field

[0001] The invention relates to the field of air-conditioning return vents, and in particular to a lightweight return vent panel. Background Art

[0002] The return air vent of the air conditioner is used for returning air. When the indoor load is certain, the amount of cold air that needs to be delivered to the room is certain. Compared with the fresh air, the temperature of the indoor air is generally lower in summer, so some air is returned to the air conditioner through the return air duct, and mixed with a small amount of fresh air to make cold air and send it into the room. Compared with using all fresh air for cooling, it can effectively save energy. Generally, the fresh air unit is used in conjunction with the fan coil unit. The fan coil unit cools the indoor air and sends it into the room, which is similar to the function of the return air duct of the central air conditioner. Due to hygiene requirements, it is necessary to equip the fresh air unit to send fresh air into the room.

[0003] Traditional return air vents often use a grille plate structure or a whole plate structure. The simple grille plate structure has low strength. Since it is located at the air outlet, a large air intake often affects the structural stability. If a whole plate is used, its own weight will reduce the service life of the entire return air vent.

[0004] A lightweight return air vent panel is now needed to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the problem that traditional return air vents in the prior art often adopt a grille plate structure or a whole plate structure. The simple grille plate structure has low strength. Since it is located at the air vent position, a large air intake volume often affects the structural stability. If a whole plate is used, the service life of the entire return air vent is reduced due to its own weight. A lightweight return air vent panel is provided to solve the above problem.

[0006] The present invention provides a lightweight return air vent panel, comprising a frame, a plurality of reinforcing columns, a plurality of supporting columns and a stabilizing mechanism, wherein the frame is a horizontally placed rectangular frame structure, the supporting columns are vertically arranged in the frame, the upper ends of the supporting columns are connected to the upper inner surface of the frame, the lower ends of the supporting columns are connected to the lower inner surface of the frame, the reinforcing columns are evenly arranged inside the frame, the upper ends of the reinforcing columns are connected to the upper inner surface of the frame, the lower ends of the reinforcing columns are connected to the lower inner surface of the frame, the number of the supporting columns is an integer multiple of the sum of the number of the reinforcing columns plus one, the number of the supporting columns between the two reinforcing columns and between the outer reinforcing columns and the side of the frame is equal and evenly arranged, and the stabilizing mechanism transversely connects the side of the frame, each reinforcing column and the supporting column and is arranged on one side of the frame, the reinforcing column and the supporting column.

[0007] The lightweight return air vent panel described in the present invention is, as a preferred embodiment, a stabilizing mechanism including a transverse connecting belt and a counterweight mechanism. The transverse connecting belt is a transverse vertical plate structure. The two ends of the transverse connecting belt are respectively connected to the inner surfaces of the two vertical edges of the frame. The middle part of the transverse connecting belt is connected to each reinforcing column and the supporting column. The counterweight mechanism is arranged in the middle part of the transverse connecting belt.

[0008] In the lightweight return air vent panel described in the present invention, as a preferred embodiment, the diameter of the reinforcing column is larger than that of the supporting column.

[0009] The lightweight return air vent panel described in the present invention, as a preferred embodiment, also includes a partition net, which is a mesh sheet structure, and is arranged on one side of the frame to fill the frame opening, and the partition net is arranged on the side opposite to the stabilizing mechanism of the frame.

[0010] In the lightweight return air vent panel described in the present invention, as a preferred embodiment, reinforcing ribs are provided at both the upper edge line position of the outer side surface of the transverse connecting belt and the lower edge line position of the outer side surface.

[0011] The beneficial effects of the present invention are as follows:

[0012] This device uses a combination of lightweight support columns and strength-designed reinforced columns, and sets a transverse connecting belt structure to reduce the shaking between columns caused by wind problems. This makes the overall device structure more stable, and since it is still a grille structure in essence, it meets the air outlet requirements. BRIEF DESCRIPTION OF THE DRAWINGS
