Description
Technical Field
[0001] The utility model relates to the technical field of air conditioners, and more specifically, to an air inlet baffle of an air conditioner. Background Technique
[0002] A central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. It uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air-conditioning system to offset the heat load of the indoor environment; the heating system provides the required heat for the air-conditioning system to offset the cooling and heating load of the indoor environment. The central air-conditioning needs to be provided with an air inlet for sucking indoor air, cooling or heating the air, and finally sending the processed air back into the room to achieve the circulation and renewal of the air.
[0003] The use of central air-conditioning has a cycle, and there is a static period throughout the year. When the air-conditioning is not in use during the static period, due to the open air inlet, it is easy for dust to enter. Although the existing central air-conditioning air inlets are generally provided with filter grilles, in order to maintain the air intake volume, the filter grilles of central air-conditioning generally have relatively large pores, resulting in dust or mosquitoes entering during the idle period, and thus frequent cleaning and wiping are required, reducing the convenience of using the air-conditioning.

[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0029] An air inlet baffle for an air conditioner, comprising an air inlet frame 1. A filter grille 2 is fixedly arranged inside the air inlet frame 1. An installation frame 3 is fixedly arranged outside the filter grille 2. A winding roller 4 is rotatably arranged inside the installation frame 3. A blocking curtain 5 is wound outside the winding roller 4. The blocking curtain 5 movably penetrates through the installation frame 3 and extends to the outside. And an insertion block 6 is fixedly arranged on the outside of the blocking curtain 5 at the part located outside the installation frame 3. A slot 8 for docking the insertion block 6 is opened inside the air inlet frame 1. And an installation groove 9 is penetratingly opened inside the air inlet frame 1. Two groups of installation blocks 12 are movably arranged inside the installation groove 9. Positioning rods 13 are fixedly arranged on the outside of the two groups of installation blocks 12. Positioning holes 7 for docking the positioning rods 13 are opened on both sides of the insertion block 6. At the same time, a blocking curtain 5 that can be conveniently stored is provided, which can completely block the air inlet. While improving the blocking effect, it will not occupy too much space and is very flexible and convenient to use.
[0030] Specifically, two groups of fixed cylinders 10 are fixedly arranged inside the installation groove 9. Moving rods 11 are movably inserted inside the two groups of fixed cylinders 10. The moving rods 11 movably penetrate through the fixed cylinders 10 and extend to the outside. And the outer ends of the moving rods 11 at the part located outside the fixed cylinders 10 are fixedly connected to the installation blocks 12. By arranging the fixed cylinders 10 and the moving rods 11, the installation of the installation blocks 12 can be limited. While facilitating the movement of the installation blocks 12, the installation stability of the installation blocks 12 is improved.
[0031] Furthermore, a spring 14 is arranged inside the fixed cylinder 10. One end of the spring 14 is connected to the fixed cylinder 10, and the other end of the spring 14 is connected to the moving rod 11. The spring 14 does not deform in the initial state. When inserting the insertion block 6 into the slot 8, first, the moving rod 11 needs to be moved towards the inside of the fixed cylinder 10 to drive the installation block 12 to move. When the moving rod 11 moves, it will squeeze the spring 14 inside the fixed cylinder 10, causing the spring 14 to deform. After the insertion block 6 is completely inserted into the slot 8, through the release of the elastic potential energy of the spring 14, the positioning rod 13 can be driven to quickly insert into the positioning hole 7 outside the insertion block 6, improving the fixing convenience and stability of the insertion block 6.
[0032] It is worth noting that an inner groove 15 is opened inside the installation frame 3. The winding roller 4 movably penetrates through the inner groove 15 and extends to the inside. And a coil spring 16 is sleeved on the part of the outside of the winding roller 4 located inside the inner groove 15. One end of the coil spring 16 is connected to the winding roller 4, and the other end of the coil spring 16 is connected to the inner groove 15. The coil spring 16 does not deform in the initial state. When using the blocking curtain 5 to seal the air inlet, the blocking curtain 5 drives the winding roller 4 to rotate. At this time, the winding roller 4 stretches the coil spring 16, causing the coil spring 16 to deform. Furthermore, through the resilience of the coil spring 16, the blocking curtain 5 can be tightened, improving the closing effect. At the same time, subsequently, through the resilience of the coil spring 16, the winding roller 4 can be driven to quickly wind up the blocking curtain 5, improving the storage convenience of the blocking curtain 5.
[0033] It should be noted that a handle 17 is fixedly arranged on the outer side of the insertion block 6. By arranging the handle 17, it is convenient to move the insertion block 6, thereby improving the usability.
[0034] In addition, a pushing block 18 is fixedly arranged on the outer side of the mounting block 12. By arranging the pushing block 18, it is convenient to move the mounting block 12, thereby improving the convenience of moving the mounting block 12.
[0035] It has to be said that a sliding block 19 is fixedly arranged on the outer side of the curtain 5, and a fixing strip 20 is fixedly arranged on the inner side of the air inlet frame 1. A sliding groove 21 for docking the sliding block 19 is formed on the outer side of the fixing strip 20. When the curtain 5 moves, it drives the sliding block 19 to slide in the sliding groove 21 in a limited manner, further improving the usability stability of the curtain 5.
[0036] Working principle: When the air conditioner is idle, push the two pushing blocks 18 to both sides. The pushing block 18 drives the movable rod 11 to move inwardly into the fixed cylinder 10. When the movable rod 11 moves, it squeezes the spring 14 in the fixed cylinder 10, causing the spring 14 to deform. Subsequently, move the insertion block 6 through the handle 17. When the insertion block 6 moves, it drives the curtain 5 to move. When the curtain 5 moves, it drives the winding roller 4 to rotate until the insertion block 6 is inserted into the slot 8. Then release the pushing block 18. At this time, the resilience of the spring 14 can drive the movable rod 11 to move outwardly from the fixed cylinder 10. When the movable rod 11 moves, it drives the mounting block 12 and the positioning rod 13 to move until the positioning rod 13 is inserted into the positioning hole 7 on the outer side of the insertion block 6, thereby facilitating the fixing of the insertion block 6 and enabling the curtain 5 to seal the air inlet to prevent dust from entering.
