[0009] Air outlet grille;

[0010] A fixing plate, which is mounted at the lower end of the air outlet grille;

[0011] A blocking mechanism is mounted on the fixing plate, and is used to prevent dust and insects from entering the air conditioning system when the air conditioning is not in use, so as not to affect the cleanliness of the indoor air when it is used next time. The blocking mechanism includes:

[0012] A rotating roller, which is mounted on the fixed plate;

[0013] A shielding cloth, which is mounted on the rotating roller;

[0014] A scroll spring installed between the fixed plate and the rotating roller;

[0015] A clamping block is installed on the shielding cloth.

[0016] Furthermore, fixed pipes are fixedly arranged at both ends of the air outlet grille, and a slide groove is provided inside the fixed pipe;

[0017] The clamping block is slidably arranged on the sliding groove opened on the inner side of the fixing tube.

[0018] Furthermore, the clamping block is located at the front end of the shielding cloth.

[0019] Furthermore, a hook is fixedly mounted on the clamping block.

[0020] Furthermore, a hanging ring is fixedly provided at the bottom of the air outlet grille.

[0021] The beneficial effect of the present application is that a central air-conditioning air supply device provided by the present application, by setting a blocking mechanism, uses a shielding cloth to cover the air outlet grille when the central air-conditioning is not in use, thereby preventing dust, insects, etc. from entering the interior of the air-conditioning system, thereby not affecting the next use.

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] like Figure 1-Figure 3 As shown, the present application provides a central air-conditioning air supply device, including a central air-conditioning body 1, wherein the central air-conditioning body 1 includes an outdoor unit and a plurality of indoor units, wherein the outdoor unit and the indoor unit are suitable for working in coordination to adjust the temperature of indoor air;

[0032] At the same time, an air supply device is provided at the air outlet position of the indoor unit, which delivers cold air or hot air to various areas of the room to achieve air temperature regulation;

[0033] The air supply device includes an air outlet grille 2 arranged at the air outlet position of the indoor unit, and the air outlet grille 2 is used to evenly distribute the air flow direction and prevent large particles from directly entering the room. At the same time, a fixing plate 4 is fixedly arranged at one end of the air outlet grille 2. It should be noted that a window is generally arranged at the air outlet position of the indoor unit of the central air conditioner, and the air outlet grille 2 is installed at the window by a fastener, and the fixing plate 4 is arranged at the upper end of the air outlet grille 2;

[0034] At the same time, a blocking mechanism 3 is provided on the fixing plate 4, and the blocking mechanism 3 is used to prevent dust, insects, etc. from entering the interior of the air conditioning system when the air conditioning is not in use, so as not to affect the cleanliness of the indoor air when it is used next time;

[0035] The blocking mechanism 3 includes a rotating roller 32 rotatably arranged on a fixed plate 4, on which a shielding cloth 34 is rolled, and a spiral spring 30 is arranged between the fixed plate 4 and the rotating roller 32, so that in the initial state, the shielding cloth 34 is completely rolled up on the rotating roller 32 under the action of the spiral spring 30, and when it is necessary to shield the air outlet grille 2, the outer end of the shielding cloth 34 is pulled to pull the shielding cloth 34 outward until the shielding cloth 34 completely covers the air outlet grille 2, so that the shielding cloth 34 can shield or expose the air outlet grille 2, thereby achieving the purpose of preventing dust from entering;

[0036] A fixed tube 33 is fixedly provided at both ends of the air outlet grille 2, a slide groove 38 is provided on the inner side of the fixed tube 33, and a clamping block 35 is fixedly provided at the outer end of the shielding cloth 34, and the clamping block 35 is slidably provided on the slide groove 38, so that when the shielding cloth 34 is pulled outward, the clamping block 35 can be stably moved by the cooperation with the slide groove 38;

[0037] A hanging ring 37 is fixedly provided at the bottom position of the air outlet grille 2, and a hook 36 is fixedly installed on the clamping block 35, so that when the shielding cloth 34 is fully pulled out, the shielding cloth 34 can be hung on the hanging ring 37 through the hook 36 to prevent the shielding cloth 34 from rolling back.

[0038] When the central air conditioner body 1 is turned off or not used for a long time, the outer end of the shielding cloth 34 is pulled outward along the slide groove 38 provided on the inner side of the fixed tube 33 until the shielding cloth 34 completely covers the air outlet grille 2, and the shielding cloth 34 is hung on the hanging ring 37 fixed at the bottom position of the air outlet grille 2 by using the hook 36 fixedly installed on the clamping block 35 to prevent the shielding cloth 34 from rolling back, so that the shielding cloth 34 can cover the air outlet, and prevent dust, insects, etc. from entering the air conditioning system when the air conditioner is not in use, so as not to affect the next use;

[0039] When the central air-conditioning body 1 is started, cold air is sent out from the air outlet grille 2. At this time, the hook 36 on the hanging ring 37 can be removed, so that the shielding cloth 34 will be completely rolled up onto the rotating roller 32 under the action of the spiral spring 30, so as to prevent the shielding cloth 34 from hindering the normal delivery of cold air from the air outlet grille 2.
