[0030] The utility model discloses an air inlet and outlet plate for a central air conditioner, which improves the practicability of installing the air outlet of a gypsum board; the utility model also provides an assembled suspended ceiling.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1-Figure 4As shown, Figure 1 This is a structural diagram of the central air-conditioning inlet and outlet plates provided by the utility model; Figure 2 for Figure 1 Structural diagram of the gypsum board after ventilation holes are opened; Figure 3 This is the structural diagram of the inner end surface of the gypsum board after the ventilation holes are opened; Figure 4 This is the end face structure diagram of the gypsum board after the ventilation holes are opened.

[0033] The present application provides a central air conditioning inlet and outlet panel, comprising a gypsum board body 1, with a mounting recess 2 for mounting inlet and outlet grilles disposed in the middle of the gypsum board body 1. The mounting recess 2 is recessed inwardly along the thickness of the gypsum board body 1, and the bottom of the mounting recess 2 is configured to provide a ventilation hole 3 extending through the thickness of the bottom wall of the recess. The mounting recess 2 is recessed inwardly along the surface of the gypsum board body 1, and the ventilation hole 3 can be disposed at the bottom of the mounting recess 2. After concealing the air conditioner or other equipment on the gypsum board, the intake and exhaust air can be transported through the ventilation hole 3. Furthermore, the mounting recess 2 allows for the installation of inlet and outlet grilles, providing space for their installation. For example, the surface of the inlet and outlet grilles can be flush with the surface of the gypsum board body 1, thereby satisfying aesthetic requirements. The inlet and outlet grilles are supported within the mounting recess 2, and the inner wall of the mounting recess 2 supports the inlet and outlet grilles, thereby improving the installation stability of the inlet and outlet grilles.

[0034] In a specific embodiment of the present case, the length direction of the slots of the installation sink 2 is arranged in the same direction as the length direction of the gypsum board body 1 .

[0035] Preferably, the mounting trough 2 is arranged along the same length as the gypsum board body 1. To accommodate gypsum boards with longer installation lengths, and to accommodate indoor installations, the air inlet and outlet grilles are arranged along the length of the wall to achieve aesthetically pleasing results. The slotted length of the mounting trough 2 is extended along the length of the gypsum board body 1, so that the assembled air inlet and outlet grilles have an aesthetically pleasing lengthwise orientation.

[0036] Furthermore, during the interior decoration process, for gypsum boards in different positions, such as the indoor top air outlet is set as a long strip structure, and the air inlet is set around the inlet and outlet length design requirements of the air-conditioning equipment, the slot length of the installation groove 2 is set to be the same length as the gypsum board body 1. For the air-conditioning outlet with aesthetic requirements, the inlet and outlet grilles can be extended to the paving direction of the gypsum board to obtain better aesthetics.

[0037] In a specific embodiment of the present case, the installation trough 2 includes a first extension portion 21 and a second extension portion 22 extending toward the inner end surface of the gypsum board body along the thickness direction of the gypsum board body, and a trough bottom wall panel 23 is arranged between the first extension portion 12 and the second extension portion 22; the ventilation hole 3 is arranged on the trough bottom wall panel 23.

[0038] The mounting trough 2 is arranged on the gypsum board body 1. For a structure in which the mounting trough 2 is only arranged in the middle of the gypsum board, an independent assembly method can be adopted to set the mounting trough 2 to have an independent structure, and perform mold preparation or assembly preparation.

[0039] To accommodate the production of gypsum boards using a conveyor belt, the mounting trough 2 is configured to be the same length as the gypsum board. The mounting trough 2 extends from the surface of the gypsum board toward the inner end face thereof, with its first and second extensions 21, 22. The trough bottom wall 23 connects the first and second extensions 21, 22, and the extension direction of the trough bottom wall 23 is along the extension direction of the gypsum board. This allows for continuous production of the gypsum board through methods such as mold casting, reducing production difficulty. Ventilation holes are provided on the trough bottom wall 23 and can be added after the gypsum board is produced or by drilling holes at the construction site, thereby meeting the requirements for air conditioning placement in different locations, enabling flexible placement of ventilation holes, and satisfying structural requirements.

[0040] In a specific embodiment of this case, a mounting pad 24 is pre-embedded within the first extension 21 and / or the second extension 22. The width of the mounting pad 24 is arranged along the thickness of the gypsum board body 1; the length of the mounting pad 24 extends along the length of the gypsum board body 1. The inlet and outlet grilles are installed within the mounting trough 2 and are fixed to the first extension 21 and the second outlet 22 with screws. To prevent cracking of the gypsum board during installation and to improve structural stability, the mounting pad 24 is pre-embedded within the first extension 21 and the second extension 22. When the inlet and outlet grilles are fixed with screws, the screws lock onto the mounting pad 24, thereby improving the structural strength of the first and second extensions 21, 22 and ensuring the structural stability of the inlet and outlet grilles.

[0041] Preferably, the length of the mounting plate 24 is not less than the length of the mounting trough 2. The mounting plate 24 can be pre-buried in the mounting trough 2 at a predetermined position. To reduce the difficulty of installing the air inlet and outlet grilles or to prevent screws from not being tightened on the mounting plate 24 due to misoperation, the mounting plate 24 can be set to be the same length as the gypsum board. Then, when screws are used to connect the air inlet and outlet grilles and the mounting trough 2 at any position of the first extension 21 and the second extension 22, the screws and the mounting plate can be accurately connected.

[0042] like Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the first installation structure of the central air-conditioning inlet and outlet plate provided by the utility model; Figure 6 This is a schematic diagram of the second installation structure of the central air-conditioning inlet and outlet plate provided by the utility model.

[0043] Based on the central air-conditioning inlet and outlet plates provided in the above embodiments, the utility model also provides an assembled ceiling, including a gypsum board assembly arranged on a wall 4 and surrounding an air-conditioning installation chamber 5.
