Description

A central air conditioning air outlet Technical Field

[0001] This utility model relates to the field of central air conditioning technology, and in particular to an air outlet for central air conditioning. Background Technology

[0002] Central air conditioning is a system that uses a main unit to control different rooms by connecting multiple terminal devices through air ducts or refrigerant pipes to achieve the purpose of indoor air conditioning. The air outlets of central air conditioning are usually relatively simple, mainly to meet basic ventilation needs, such as simple grille-type air outlets.

[0003] However, in practical use, grille-type air vents are not flexible enough in adjusting airflow distribution. The shape and spacing of the grilles can cause airflow to easily form specific directions and areas when it is delivered, making it difficult to achieve airflow diffusion over a large area. Furthermore, because there are gaps between the grilles of grille-type air vents, dust can easily enter and accumulate on the filter and grille surface inside the vent. Since central air conditioning systems are usually installed inside decorative panels, disassembly is inconvenient during cleaning and can easily damage the decorative panels, affecting the overall aesthetics of the room. In view of this, this application proposes an air outlet for central air conditioning systems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in adjusting the airflow diffusion area at the air outlet and inconvenience in cleaning when a lot of dust accumulates after long-term use, and to propose an air outlet for central air conditioning.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A central air conditioning air outlet includes a mounting base, an extension base fixedly connected to one side of the mounting base, a filter screen disposed inside the extension base, a sealing plate fixedly connected to the other side of the mounting base, two insert rods symmetrically arranged on the top inner wall of the mounting base, and an assembly frame mounted inside the mounting base via two symmetrically arranged hinges.

[0007] The assembly frame is equipped with two connecting plates. One side of the connecting plate is provided with multiple first blades, and the other side of the connecting plate is provided with multiple second blades.

[0008] As a further preferred embodiment of this technical solution, the top of the assembly frame has two symmetrically provided limiting grooves, and the positions of the limiting grooves correspond to the positions of the insertion rods.

[0009] As a further preferred embodiment of this technical solution, the top of the assembly frame has two grooves, and a fixing rod is provided in each of the two grooves, with both ends of the fixing rod being fixedly connected to the inner wall of the groove.

[0010] The bottom of the assembly frame is provided with a positioning groove, and an iron block is placed inside the positioning groove.

[0011] As a further preferred embodiment of this technical solution, the top of the connecting plate extends into the groove, and the top of the connecting plate is rotatably connected to the fixing rod.

[0012] A magnetic block is fixedly connected to the bottom of the connecting plate, the bottom of the connecting plate extends into the positioning groove, and the size of the magnetic block corresponds to the size of the iron block.

[0013] As a further preferred embodiment of this technical solution, the plurality of first blades are all horizontally arranged and equidistant from each other, and the ends of the plurality of first blades near the connecting plate are all embedded in the connecting plate.

[0014] As a further preferred embodiment of this technical solution, one end of each of the plurality of second blades extends outside the assembly frame, and the other end of each of the plurality of second blades is fixedly connected to a rotating shaft. The plurality of rotating shafts are respectively embedded in the connecting plate at corresponding positions, and the plurality of rotating shafts are rotatably connected to the connecting plate through friction.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, through the setting of a connecting plate, a first blade and a second blade, can adjust the flow direction of the air at the air outlet by moving the second blade under the limit of the rotating shaft. By changing the angle difference between the second blade and the first blade, the airflow blown out at the air outlet is finally divided and guided, flexibly adjusting the coverage area of ​​the airflow at the central air conditioning outlet, avoiding discomfort caused by direct blowing, and achieving the effect of rapid adjustment of indoor temperature.

[0017] 2. This utility model, through the provided groove, fixing rod, and magnetic block, allows for further disassembly of the assembly frame. When cleaning is required, the assembly frame and mounting base are separated by the hinge. Under the limitation of the fixing rod, the first and second blades on the connecting plate can be flipped to the bottom of the assembly frame, avoiding damage to the interior trim panels caused by cumbersome disassembly. This facilitates the cleaning or replacement of the filter screen inside the mounting base by maintenance personnel. At the same time, it allows for relatively convenient cleaning of the first and second blades separately, reducing cleaning dead corners and improving the cleanliness of the central air conditioning's air supply.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] This utility model provides the following technical solution: As shown in Figures 1-3, a central air conditioning air outlet includes a mounting base 1. An extension base is fixedly connected to one side of the mounting base 1, and the mounting base 1 is fixed by connecting the extension base to the air duct. A filter screen 2 is provided inside the extension base to filter the gas delivered by the fan and prevent dust carried in the gas from being blown into the room. A sealing plate is fixedly connected to the other side of the mounting base 1 to cooperate with the interior decoration panel and improve the overall aesthetics. Two insert rods 11 are symmetrically arranged on the top inner wall of the mounting base 1. An assembly frame 3 is installed inside the mounting base 1 through two symmetrically arranged hinges 12. The top of the assembly frame 3 is symmetrically arranged. Two limiting grooves 31 are provided, and the positions of the limiting grooves 31 correspond to the positions of the insertion rods 11. It should be noted that elastic pads are provided on both sides of the top of the insertion rods 11 to increase the friction between the insertion rods 11 and the inner walls of the limiting grooves 31. By inserting the insertion rods 11 into the corresponding limiting grooves 31, the assembly frame 3 can be fixed and installed in the mounting base 1. When Xu Yahong disassembles, the top of the assembly frame 3 can be pulled directly to move the insertion rods 11 out of the limiting grooves 31, thereby completing the disassembly of the assembly frame 3. Under the limit of the hinge 12, the assembly frame 3 flips downward, at which time the filter screen 2 in the mounting base 1 can be directly cleaned or replaced.

[0027] As shown in Figures 4 and 5, two connecting plates 4 are installed on the assembly frame 3. Two grooves 32 are formed on the top of the assembly frame 3, and fixing rods 33 are respectively installed in the two grooves 32. Both ends of the fixing rods 33 are fixedly connected to the inner wall of the groove 32. A positioning groove 34 is formed on the bottom of the assembly frame 3, and an iron block is placed inside the positioning groove 34. The top of the connecting plate 4 extends into the groove 32, and the top of the connecting plate 4 is rotatably connected to the fixing rod 33. A magnetic block 41 is fixedly connected to the bottom of the connecting plate 4, and the bottom of the connecting plate 4 extends into the positioning groove 34. The dimensions correspond to the dimensions of the iron block. It should be noted that when the assembly frame 3 is disassembled, the end of the connecting plate 4 can be pulled to move. When the end of the connecting plate 4 moves out of the positioning groove 34, the magnetic block 41 separates from the iron block in the positioning groove 34. Under the limit of the fixing rod 33, the connecting plate 4 will rotate around the fixing rod 33 as the axis and finally flip to the bottom of the assembly frame 3. The stopping positions of the first blade 5 and the second blade 6 on the connecting plate 4 are convenient for cleaning personnel to handle. By further disassembling the assembly frame 3, it is convenient to clean the dead corners and avoid affecting the air quality during the subsequent air supply process.

[0028] As shown in Figure 6, a plurality of first blades 5 are provided on one side of the connecting plate 4. All first blades 5 are horizontally arranged and equidistant from each other. The ends of the first blades 5 closest to the connecting plate 4 are embedded in the connecting plate 4. A plurality of second blades 6 are provided on the other side of the connecting plate 4. One end of each second blade 6 extends beyond the assembly frame 3, and the other end of each second blade 6 is fixedly connected to a rotating shaft 61. The rotating shafts 61 are respectively embedded in the corresponding positions of the connecting plate 4, and are rotatably connected to the connecting plate 4 through friction. It should be noted that... By moving the end of the second blade 6 away from the connecting plate 4, the position of the second blade 6 is limited by the friction of the rotating shaft 61. This allows for flexible adjustment of the guiding effect of the second blade 6 on the airflow. Depending on the installation position and usage scenario, the angle between the second blade 6 and the first blade 5 can be adjusted to further divide the airflow passing through the first blade 5, forming multiple sets of gas flow fields in different directions. This reduces dust adhesion through changes in gas velocity, while also covering a large indoor area, avoiding discomfort to users caused by direct airflow, and quickly completing indoor air exchange to adjust the indoor temperature.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
