However, the temperature requirements of each room are different, and adjusting the temperature according to the actual situation can lead to high energy consumption of the air conditioning system. Summary of the Invention

[0004] The purpose of this invention is to address the problem that in existing central air conditioning systems, cold or hot air is directly discharged through the air outlet during temperature control. However, since the temperature requirements in each room are different, the direct discharge of cold or hot air leads to high energy consumption when adjusting according to actual conditions. Therefore, this invention proposes an energy-saving temperature control component for central air conditioning.

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

[0006] A temperature control component for energy saving in central air conditioning includes an upper housing, a mixing housing, and an air outlet plate. The mixing housing is connected between the upper housing and the air outlet plate.

[0026] 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.

[0027] Reference Figures 1-4 This utility model provides a temperature control component for energy saving in central air conditioning, including an upper housing 1, a mixing housing 2, and an air outlet plate 3. The mixing housing 2 is connected between the upper housing 1 and the air outlet plate 3. The cross-section of the mixing housing 2 is larger than that of the upper housing 1. The upper housing 1 is divided into a hot and cold channel 102 and a normal temperature channel 103 by an air baffle 101, which are used for guiding hot and cold air and normal temperature gas, respectively. Both the hot and cold channel 102 and the normal temperature channel 103 are equipped with movable valve plates 6. An upper mixing fan 604 for auxiliary gas mixing is provided at the connection between the upper housing 1 and the mixing housing 2. The mixing housing 2 is equipped with a HEPA filter 5 and a temperature sensor 7. The temperature sensor 7 and the upper mixing fan 604 are electrically connected to the terminal equipment. The surface of the air outlet plate 3 has an air outlet groove 301 corresponding to the mixing housing 2. Multiple movable air guide plates 4 are provided in the air outlet groove 301.

[0028] Furthermore, the valve plate 6 is rotatably connected to both sides of the baffle plate 101 via hinges, and the upper housing 1 or the baffle plate 101 is provided with a first electric push rod 602 that pushes the valve plate 6 to rotate. The first electric push rod 602 is electrically connected to the terminal equipment.

[0029] When the device is in use, cold or hot air generated by the central air conditioning equipment enters the upper housing 1 through the cold / hot channel 102 via the connection between the upper housing 1 and the air inlet duct. At room temperature gas enters the upper housing 1 through the room temperature channel 103. By controlling the extension and retraction of the first electric push rod 602, the rotation of the valve plate 6 can be controlled, thereby controlling the opening size of the valve plate 6. After passing through the valve plate 6, the gas enters the upper housing 1. Combined with the rotation of the mixing fan 604, the gas is mixed, ensuring that it enters the mixing chamber 2 at a balanced temperature. In the center, the temperature is controlled by mixing hot and cold gas with room temperature gas, which can improve the utilization rate of hot and cold gas and save energy. The gas is filtered and purified by HEPA filter 5. After the air guide plate 4 is opened, the mixed and filtered gas can be discharged through the air guide plate 4. In the device, the outlet air temperature can be detected by temperature sensor 7. After the terminal equipment receives the feedback data from temperature sensor 7, it can adjust the outlet air temperature by controlling the first electric push rod 602. In conjunction with the mixing fan 604, the air volume can be controlled.

[0030] As one possible implementation, the air outlet plate 3 is provided with a shroud 8 corresponding to the mixing chamber 2, and the temperature sensor 7 is installed on the shroud 8. The shroud 8 has a door-shaped structure, and its movable end is connected to the inner wall of the air outlet plate 3, which can form an isolation effect on the filter HEPA 5 and the air guide plate 4.

[0031] Specifically, the inner wall of the upper housing 1 is connected to a grid baffle 601 corresponding to the valve plate 6. One end of the grid baffle 601 contacts the upper surface of the valve plate 6. When the upper surface of the valve plate 6 contacts the grid baffle 601, there is a gap between the valve plate 6 and the inner wall of the upper housing 1. With this setting, the position of the valve plate 6 can be limited by the grid baffle 601. When the first electric push rod 602 pulls the valve plate 6, the valve plate 6 moves closer to the grid baffle 601. The grid baffle 601 limits the position of the valve plate 6, avoiding the valve plate 6 from getting stuck and making the valve plate 6 more flexible when rotating.

[0032] Please refer to this again. Figure 4 The grille 601 includes a straight rod connected to the inner wall of the upper housing 1. Multiple protruding strips are connected to this straight rod, with the ends of the protruding strips away from the straight rod contacting the valve plate 6. For specific installation instructions, please refer to the accompanying drawings. Figure 1As shown, the straight rod on the grille 601 is horizontally connected to the inner wall of the upper housing 1, and the convex strip is connected to the straight rod, forming a comb-like structure. The convex strip provides a limiting effect on the valve plate 6. Preferably, the straight rod and the convex strip are an integral structure, and are fixedly installed on the inner wall of the upper housing 1. Furthermore, the inner wall of the upper housing 1 is provided with an air guide frame 603. The lower ends of the two air guide frames 603 are close to each other and extend towards the upper mixing fan 604. Please refer again to Figure 1 The air entering the upper chamber 1 can be guided into the upper chamber 1 through the valve plate 6 and the inner wall of the upper chamber 1. With the help of the air guide frame 603, the air can be guided to deliver cold air or hot air and room temperature air to the position of the upper mixing fan 604. After the upper mixing fan 604 rotates, it can mix the air. The mixed gas is filtered through the HEPA filter 5 and then discharged to make the gas more uniform. By controlling the first electric push rod 602 to push the valve plate 6 to rotate at different angles, the opening size of the valve plate 6 can be controlled to achieve temperature control.

[0033] It is worth mentioning that the bottom surface of the HEPA filter 5 is equipped with an antibacterial filter layer 501. The HEPA filter 5 and the antibacterial filter layer 501 are used for filtration and purification. Inside the mixing chamber 2, multiple lower mixing fans 502 are connected by connecting rods. The lower mixing fans 502 are located between the HEPA filter 5 and the temperature sensor 7. The lower mixing fans 502 are electrically connected to the terminal equipment. When the lower mixing fans 502 are powered on by the terminal equipment, they rotate, which can remix the filtered air, making the air outlet more uniform and the air outlet effect better.

[0034] In this embodiment, when the air guide plate 4 is installed, both ends of the air guide plate 4 are rotatably connected to the symmetrical inner walls of the air outlet trough 301. It also includes a slidably arranged guide rod 401. A connecting arm 402 is rotatably connected between the air guide plate 4 and the guide rod 401. The air outlet plate 3 or the mixing box 2 is provided with a second electric push rod 403 that pushes the guide rod 401 to slide. The second electric push rod 403 is electrically connected to the terminal equipment. After the second electric push rod 403 extends or shortens, it can push the guide rod 401 to move. The rotation of the connecting arm 402 pushes the air guide plate 4 to rotate, thereby controlling the opening angle of the air guide plate 4 and thus adjusting the direction of the air conditioner air outlet.

[0035] Furthermore, there are two guide rods 401, which are located near the two ends of the length of the air guide plate 4. The two guide rods 401 are connected by a rod-shaped connector to form a "U" or "H" shaped structure. The second electric push rod 403 is connected to the rod-shaped connector.

[0036] The working principle of this utility model is as follows:

[0037] When the device is in use, cold or hot air generated by the central air conditioning equipment enters the upper housing 1 through the cold / hot channel 102 via the connection between the upper housing 1 and the air inlet duct. At room temperature gas enters the upper housing 1 through the room temperature channel 103. By controlling the extension and retraction of the first electric push rod 602, the rotation of the valve plate 6 can be controlled, thereby controlling the opening size of the valve plate 6. After passing through the valve plate 6, the gas enters the upper housing 1. Combined with the rotation of the mixing fan 604, the gas is mixed, ensuring that it enters the mixing chamber 2 at a balanced temperature. In this device, temperature regulation is achieved by mixing hot and cold gases with ambient temperature gases, which can improve the utilization rate of hot and cold gases and save energy. The gas is filtered and purified by the HEPA filter 5. After the air guide plate 4 is opened, the mixed and filtered gas can be discharged through the air guide plate 4. Furthermore, the outlet air temperature can be detected by the temperature sensor 7. After the terminal equipment receives the feedback data from the temperature sensor 7, it can adjust the outlet air temperature by controlling the first electric push rod 602. In conjunction with the mixing fan 604, the air volume can be controlled.
