[0002] Air conditioning, also known as air conditioner, is a unit used to provide air temperature changes in a confined space (such as a room, building, etc.). Its main function is to adjust the parameters such as air temperature, humidity, cleanliness and air flow rate in the space to meet the requirements of human comfort or process.

[0003] Central air conditioning system has the advantages of large air handling capacity, centralized cold and heat sources, and reliable equipment operation. It is widely used in public places and homes. It controls different rooms through a host connected to multiple terminal devices through air ducts or refrigerant pipes to achieve the purpose of indoor air conditioning. The most prominent feature of central air conditioning is that it creates a comfortable living environment. Secondly, from the aesthetic point of view and the best use of space, the use of central air conditioning makes interior decoration more flexible and easier to achieve various decorative effects. Even if the decoration is redecorated, the original central air conditioning system can be slightly changed to be in harmony with the new decoration.

[0026] like Figure 1-Figure 5As shown, a low-noise fixed-frequency air conditioner air outlet box comprises: an air inlet pipe 1, the air inlet pipe 1 comprises a connecting pipe 11 and a connecting flange 12 fixedly connected to the connecting pipe 11, the bottom of the connecting pipe 11 is connected to a control box 2, the inner top of the control box 2 is provided with a limited circular groove 21, the limited circular groove 21 is rotatably connected with a rotation adjustment device 3, the rotation adjustment device 3 is provided with a telescopic adjustment device 4, the bottom of the telescopic adjustment device 4 is connected to an air outlet box 5, and the side of the air outlet box 5 is provided with an air outlet 51;

[0027] The direction of the air outlet 51 is controlled by rotating the rotary adjustment device 3. After the central air conditioner is turned off, the air outlet 51 is isolated from the outside world by contracting the telescopic adjustment device 4 to prevent the outside dust from entering.

[0028] In the present embodiment, if the air outlet 51 of the air conditioner is facing people for a long time, cold air will be turned on in summer, and the temperature of the cold air is much lower than the outside temperature, so that people facing the wind will easily catch a cold, while hot air will be turned on in winter and people will easily feel hot. At this time, the main shaft of the transmission motor 34 can be rotated by rotating the rotating adjustment device 3, thereby driving the active pulley 35 to rotate, and driving the driven pulley 33 to rotate through the transmission belt 36, and then the upper sleeve 31 is rotated on the limiting circular groove 21 to adjust the horizontal angle of the air outlet 51. When the air conditioner is turned off, the two telescopic electric cylinders 42 on the telescopic adjustment device 4 will shrink, driving the air outlet box 5 slidingly engaged on the limiting slide groove 44 to retract into the square through groove 32, isolating the air outlet 51 from smoke and dust. When the air conditioner is turned on, the two telescopic electric cylinders 42 will extend, so that the air outlet box 5 extends, and then the air outlet 51 is exposed.

[0029] As an optional implementation, Figure 2 , 3 As shown in , 4, the rotation adjustment device 3 includes an upper sleeve 31 rotatably connected to the limiting circular groove 21, a square through groove 32 is arranged in the upper sleeve 31, a driven pulley 33 is fixedly connected to the top of the upper sleeve 31, a transmission motor 34 is arranged on the inner top of the control box 2, a driving pulley 35 is transmission-connected on the main shaft of the transmission motor 34, and a transmission belt 36 is transmission-connected between the driven pulley 33 and the driving pulley 35;

[0030] In this way, a basis for the air outlet box 5 to rotate is provided.

[0031] As an optional implementation, Figure 2 , 3As shown in , 4, the telescopic adjustment device 4 includes two connecting blocks 41 fixedly connected to the upper ends of the two diagonal ends of the square through slot 32, a telescopic electric cylinder 42 is arranged at the bottom of each connecting block 41, and a transmission block 43 is fixedly connected to the bottom telescopic end of each telescopic electric cylinder 42, and two symmetrically arranged limiting slide grooves 44 are arranged at the bottom of the square through slot 32, and the limiting slide grooves 44 are slidably matched with the air outlet box 5, and the top of the air outlet box 5 is fixedly connected to the two transmission blocks 43;

[0032] In this way, a basis for the expansion and contraction of the air outlet box 5 is provided.

[0033] As an optional implementation, Figure 2 , 3 As shown in 4, the air outlet box 5 is fitted with a sound-absorbing cotton 45;

[0034] In this way, the sound-absorbing cotton 45 can reduce the noise emitted by the operation of the air conditioner.

[0035] As an optional implementation, Figure 5 As shown, the air outlet 51 is provided with an air outlet louver 52;

[0036] In this way, the air outlet 51 is provided with guidance of the up and down wind directions.

[0037] As an optional implementation, Figure 1 , 5 As shown, a mounting slot frame 53 is provided at the edge of the air outlet 51, and two magnetic pressure frames 54 are magnetically connected to the left and right ends of the mounting slot frame 53;

[0038] In this way, the mounting slot frame 53 is made of ferromagnetic material, and the magnetic pressure frame 54 is magnetically adsorbed in the mounting slot frame 53. When it is necessary to import air-conditioned hot or cold air into individual rooms, the air outlet 51 is externally connected to an air-conditioning air guide bag (a long cylindrical plastic bag), and the edge of the air-conditioning air guide bag is set in the mounting slot frame 53. The air-conditioning air guide bag is fixed to the mounting slot frame 53 through the magnetic pressure frame 54, and the other end of the air guide bag is passed into the room that needs air conditioning. In a room without air conditioning, the air-conditioning air guide bag can transmit cold air or hot air to the room. Compared with the cost of adding the terminal air outlet 51, the use of this product is low-cost.
