Description

Technical Field

[0001] This utility model relates to the field of air conditioning and refrigeration equipment technology, and in particular to a quick-release structure for an air conditioning inlet and a central air conditioning system. Background Technology

[0002] Currently, air conditioners (especially central air conditioning systems) typically have one air outlet and one air inlet (return air inlet) in their indoor units. Generally, for buildings with suspended ceilings on all four sides, the return air inlet is often designed at the bottom of the ceiling, while the air inlet is designed on the side of the ceiling. Traditional air inlet (return air inlet) designs include an air inlet frame and an air inlet grille hinged to a through-hole in the middle of the air inlet frame. The air inlet grille opens by flipping up and down, and after closing, it is locked by elastic pins located at both ends (along the length) of the air inlet frame. Whether opening or closing, it usually requires climbing a ladder to each end of the air inlet frame to operate the elastic pins separately, making the operation very cumbersome.

[0003] Therefore, it is necessary to develop a quick-release structure for the air conditioner inlet to overcome the aforementioned technical problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a quick-release structure for air conditioning inlet and a central air conditioning system, which effectively overcomes the defects of the prior art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A quick-release structure for an air conditioner air inlet includes a horizontally arranged rectangular air inlet frame and a rectangular air inlet grille. One long side of the air inlet grille is hinged to the inner side of one long side of the air inlet frame, and the other long side of the air inlet grille is detachably connected to the other long side of the air inlet frame via a quick-release structure.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, a filter screen is detachably installed on the inner side of the aforementioned air inlet grille.

[0009] Furthermore, the lower surface of the aforementioned air inlet frame is provided with a groove around the central through hole that is adapted to the aforementioned air inlet grille, and one long side of the aforementioned air inlet grille is hinged to one long side of the aforementioned groove.

[0010] Furthermore, the aforementioned quick-release structure includes a rotating shaft and a support block. Multiple mounting plates are spaced along the length of the inner side of the other long side of the air inlet frame. The rotating shaft passes through the multiple mounting plates and is rotatably connected to them. A threaded section is provided on the surface of the rotating shaft. An internal thread adapted to the threaded section is provided in the support block. The support block is screwed onto the threaded section and slidably connected to the inner surface of the other side of the air inlet frame. A support portion corresponding to the support block protrudes from the inner side of the other side of the air inlet grille. The air inlet grille is provided with a driving member connected to the rotating shaft. The driving member drives the rotating shaft to rotate and moves the support block axially along the rotating shaft, thereby causing the support block to translate between the corresponding support portion and the air inlet grille, or to the side of the support portion.

[0011] Furthermore, the aforementioned support portion is an L-shaped plate.

[0012] Furthermore, the surface of the aforementioned rotating shaft is provided with multiple threaded segments at intervals along its long axis, and the aforementioned support blocks are provided in multiple ways, each correspondingly screwed onto one of the aforementioned threaded segments.

[0013] Furthermore, a limiting baffle is provided at the same end of each of the aforementioned support components.

[0014] Furthermore, the aforementioned driving component is a roller-shaped knob, and a slot is provided on the other side of the air inlet grille corresponding to the knob. The driving component is embedded in the slot and partially exposed to the outside of the air inlet grille.

[0015] Furthermore, the outer surface of the aforementioned knob is provided with an anti-slip structure.

[0016] The advantages of this utility model are: the structure is simple and reasonable, and the quick-release structure allows the air inlet grille to be opened or closed quickly and easily relative to the air inlet frame, making operation convenient.

[0017] A central air conditioning system is also provided, including a quick-release structure for the air conditioning inlet. Attached Figure Description

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0023] Example 1

[0024] like Figure 1 and 2 As shown, the quick-release structure for the air conditioning inlet of this embodiment includes a horizontally arranged rectangular air inlet frame 1 and a rectangular air inlet grille 2. One long side of the air inlet grille 2 is hinged to the inner side of one long side of the air inlet frame 1, and the other long side of the air inlet grille 2 is detachably connected to the other long side of the air inlet frame 1 through a quick-release structure.

[0025] In this embodiment, the quick-release structure for the air conditioning inlet allows for locking and unlocking of the inlet frame 1 simply by operating the quick-release structure during the opening or closing of the inlet grille 2. This is very convenient. Compared to traditional inlet designs, it only requires one operation and can be performed from one location. This improves upon the drawbacks of traditional technologies that require moving back and forth and climbing ladders multiple times, enhances safety during the closing or opening process, and simplifies the operation procedure.

[0026] In this embodiment, a filter screen is detachably installed on the inner side of the air inlet grille 2.

[0027] In a preferred embodiment, the lower surface of the air inlet frame 1 is provided with a groove that is adapted to the air inlet grille 2 around the central through hole, and one long side of the air inlet grille 2 is hinged to one long side of the groove.

[0028] In the above implementation scheme, the groove design is adapted to the shape of the air inlet grille 2. After the air inlet grille 2 is closed, it can be well embedded in the groove, with a smooth surface and a more beautiful appearance.

[0029] In a preferred embodiment, the quick-release structure includes a rotating shaft 31 and a support block 32. Multiple mounting plates 11 are spaced apart along the length of the inner side of the other long side of the air inlet frame 1. The rotating shaft 31 passes through the multiple mounting plates 11 and is rotatably connected to them. A threaded section 311 is provided on the surface of the rotating shaft 31. An internal thread adapted to the threaded section 311 is provided in the support block 32. The support block 32 is screwed onto the threaded section 311 and slidably connected to the inner surface of the other side of the air inlet frame 1. A support portion 21 corresponding to the support block 32 protrudes from the inner side of the other side of the air inlet grille 2. The air inlet grille 2 is provided with a driving member 33 connected to the rotating shaft 31. The driving member 33 drives the rotating shaft 31 to rotate and moves the support block 32 along the axial direction of the rotating shaft 31, thereby causing the support block 32 to translate between the corresponding support portion 21 and the air inlet grille 2, or to the side of the support portion 21.

[0030] In the above implementation scheme, when opening, the operating drive component 33 drives the rotating shaft 31 to rotate, causing the support block 32 to translate from between the support part 21 and the air inlet grille 2 to the side of the support part 21. At this time, the air inlet grille 2 can freely flip up and down. When closing, the air inlet grille 2 is flipped upwards. After it is in place, the operating drive component 33 drives the rotating shaft 31 to rotate in the opposite direction to when it is open, causing the support block 32 to move in the opposite direction between the support part 21 and the air inlet grille 2. At this time, the support part 21 is hooked against the upper end of the corresponding support block 32, which can achieve locking. The operation process only requires flipping the air inlet grille 2 and rotating the rotating shaft 31 at the position of the drive component 33. The entire process only requires placing a ladder below the corresponding drive component 33, and only requires one operation, which is very quick and convenient.

[0031] In this embodiment, the support part 21 is an L-shaped plate. This shape design ensures that the support block 32 can be moved relative to it to the lower end of the horizontal plate surface of the support part 21 to play a better locking role, or moved to the side of the support part 21.

[0032] In a preferred embodiment, the surface of the rotating shaft 31 is provided with multiple threaded segments 311 at intervals along its long axis, and the support block 32 is provided with multiple segments, which are screwed onto the multiple threaded segments 311 respectively.

[0033] In the above implementation scheme, multiple support blocks 32 provide multi-point support and locking in the length direction of the air inlet grille 2 to ensure the structural stability of the air inlet grille 2 after it is closed.

[0034] In this embodiment, a limiting baffle 211 is provided at the same end of each of the aforementioned support portions 21. The multiple limiting baffles 211 restrict the depth to which the support block 32 moves between the support portion 21 and the air inlet frame 1, ensuring that it will not move out of the support portion 21 due to excessive translation.

[0035] In this embodiment, the driving component 33 is a roller-shaped knob. A slit is provided on the other side of the air inlet grille 2 corresponding to the knob. The driving component 33 is embedded in the slit and partially exposed to the outside of the air inlet grille 2. The driving component 33 has a simple structural design and can be operated with only a certain amount of external force, making it very convenient and simple.

[0036] In this embodiment, the outer surface of the knob is provided with an anti-slip structure. This ensures that the knob will not slip against the user's hand during operation, making the operation smoother.

[0037] In this embodiment, the anti-slip structure is a set of raised dots or stripes evenly distributed on the outer peripheral surface of the knob.
