Description

Technical Field

[0001] The utility model relates to the technical field of central air-conditioning refrigeration energy saving, in particular to a central air-conditioning energy-saving device. Background Technique

[0002] The central air-conditioning system consists of one or more cold and heat source systems and multiple air-conditioning systems. Different from the traditional refrigerant air-conditioning, it centrally processes air to meet the comfort requirements. It uses the principle of liquid gasification refrigeration to provide the required cooling capacity for the air-conditioning system to offset the cooling load of the indoor environment;

[0003] The heating system provides the required heat for the air-conditioning system to offset the heat load of the indoor environment.

[0004] Chinese Patent Publication No. CN220852519U discloses a central air-conditioning energy-saving device, which includes a shunt plate for shunting the air inside the air outlet pipe of the central air-conditioning. A box cover is fixedly arranged on the top of the shunt plate; different-direction guide components are evenly distributed on the shunt plate; the guide components are communicated with the air outlet pipe of the central air-conditioning through main connecting pipes.

[0005] In the central air-conditioning energy-saving device in the above patent, the cold air generated by the central air-conditioning can be evenly distributed mainly through the guide components evenly arranged on the shunt plate, and the bent air outlet pipes are installed to bend in different directions according to different directions, so that the cold air of the central air-conditioning can be evenly blown in different directions in the room.

[0006] However, in the above technology, the orientation of the air outlet of the air-conditioning is formed by connecting a single sub-connecting pipe with multiple guide pipes. However, after the air enters the inside of the guide pipe in the sub-connecting pipe, a large resistance will be generated, so it is easy to cause the pressure of the air discharged through the guide pipe to be small, resulting in a small diffusion area of the cold air;

[0007] And there is only one set of guide components in each direction, and a single set of guide components is prone to low power, resulting in a slow refrigeration speed and the problem of requiring long-term refrigeration. Therefore, when refrigeration is required in a single direction, the refrigeration efficiency is low. Utility Model Content

[0008] In view of the deficiencies of the existing technology, the purpose of the present utility model is to provide a central air-conditioning energy-saving device to facilitate solving the technical problems mentioned in the above background technique.

[0009] The above technical purpose of the present utility model is achieved through the following technical solutions:

At the top end of the air - conditioning box body, there is a driving turntable, and at the positions corresponding to the driving turntable on the outer peripheral walls of each of the installation cylinder frames, there are transmission tooth grooves.

[0011] Further, the diffusion mechanism includes a telescopic pipe.

At the bottom end of the telescopic pipe, there is an adjustment frame. On both sides of the adjustment frame, there are electric telescopic rods, and the top ends of the electric telescopic rods are rotatably connected to the side wall of the diversion pipe.

[0012] Further, on the bottom side of the inner pipe wall of the diversion pipe, there is a sliding groove. The outer wall of the sliding frame fits with the groove wall of the sliding groove. The inner pipe wall of the diversion pipe is aligned with the inner pipe wall of the telescopic pipe.

[0013] Further, the driving turntable includes a driving motor. The driving motor is inserted at the center of the upper end of the air - conditioning box body. At the top end of the driving motor, there is a rotating disk. Inside the rotating disk, there is an installation cavity. On the side wall of the rotating disk, there are several positioning grooves. Inside each of the positioning grooves, there is a driving tooth. Inside the installation cavity, there is a locking mechanism.

[0014] Further, the locking mechanism includes a fixed shaft rod.

[0016] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0017] 1. The central air-conditioning energy-saving device connects the air outlet pipe of the air conditioner with the shunt cylinder. When the air conditioner is in use, the gas discharged from the air conditioner enters the interior of the diversion pipe through the shunt cylinder. Since the bottom end of the shunt cylinder is smoothly connected to the diversion pipe, when the air is shunted when entering the diversion pipe, it can pass through smoothly, thus avoiding the problem of air blockage caused by the step between the diversion pipe and the shunt cylinder and the resulting small air pressure.

[0018] 2. The central air-conditioning energy-saving device is provided with a diffusion mechanism for guiding the air outlet of the diversion pipe, enabling the air to be discharged in multiple directions. And with the setting of the driving turntable and the transmission tooth grooves, the angle of the diffusion mechanism can be adjusted, so that the air discharged from the air conditioner can supply air to each position simultaneously, improving the cooling efficiency when the air conditioner cools a certain place alone. When the temperature drops to a relatively comfortable state, some air outlets are stopped to reduce the power of the air conditioner, achieving the effect of energy conservation and emission reduction, and effectively avoiding the situation that it is difficult to cool due to the low power of a single air outlet.

Detailed implementation mode

[0027] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0028] Embodiment:

[0029] Refer to Figures 1-6 , a central air-conditioning energy-saving device disclosed by the present utility model includes an air conditioner box body 1. Four mounting holes 2 are provided inside the air conditioner box body 1. Mounting cylinder frames 3 are rotatably arranged inside the mounting holes 2. A rectangular fixing pipe 4 is provided inside the mounting cylinder frames 3. A shunt cylinder 5 is provided inside the rectangular fixing pipe 4. A plurality of diversion pipes 6 are provided at the bottom end of the shunt cylinder 5. The contact surfaces of adjacent two diversion pipes 6 are arc-shaped. A diffusion mechanism 7 is provided at the bottom end of the diversion pipe 6. A driving turntable 8 is provided at the top end of the air conditioner box body 1. Transmission tooth grooves 9 are provided at positions corresponding to the outer peripheral walls of the mounting cylinder frames 3 and the driving turntable 8.

[0030] In this embodiment, when in use, the air outlet pipe of the air conditioner is communicated with the shunt cylinder 5. When the air conditioner is in use, the gas discharged from the air conditioner enters the inside of the diversion pipe 6 through the shunt cylinder 5. Since the bottom end of the shunt cylinder 5 and the diversion pipe 6 are smoothly connected, when the air is shunted when entering the diversion pipe 6, it can pass through smoothly, thus avoiding the problem that there is a step between the diversion pipe 6 and the shunt cylinder 5, resulting in air blockage and a small air pressure.

[0031] At the same time, the diffusion mechanism 7 is provided to guide the air outlet of the diversion pipe 6, so that the air can be discharged in multiple directions. And with the setting of the driving turntable 8 and the transmission tooth groove 9, the angle of the diffusion mechanism 7 can be adjusted, so that the air discharged from the air conditioner can supply air to each position simultaneously, improving the cooling efficiency when the air conditioner cools a certain place alone. When the temperature drops to a more comfortable state, some air outlets are stopped, achieving the effect of energy conservation and emission reduction, effectively avoiding the situation that it is difficult to cool down due to the low power of a single air outlet.

[0032] In a further preferred embodiment of the present utility model, as Figures 1-6As shown, the diffusion mechanism 7 includes a telescopic tube 71. A sliding frame 72 is provided at the top end of the telescopic tube 71, and the sliding frame 72 is slidably connected to the side wall of the diversion tube 6. An adjustment frame 73 is provided at the bottom end of the telescopic tube 71. Electric telescopic rods 74 are provided on both sides of the adjustment frame 73, and the top ends of the electric telescopic rods 74 are rotatably connected to the side wall of the diversion tube 6.

[0033] In this embodiment, the top end of the telescopic tube 71 is slidably connected to the diversion tube 6 through the sliding frame 72, and the adjustment frame 73 is provided to fix the bottom diameter of the telescopic tube 71. The adjustment frame 73 is connected to the side wall of the diversion tube 6 through the electric telescopic rods 74.

[0034] By the telescopic movement of the electric telescopic rods 74, the inclination angle of the adjustment frame 73 is controlled, so as to adjust the orientation of the bottom nozzle of the telescopic tube 71, enabling the telescopic tube 71 to face different directions, thereby achieving the purpose of adjusting the air outlet direction and air outlet angle, increasing the diffusion area and uniformity of the air outlet of the air conditioner, and thus improving the cooling efficiency.

[0035] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, a sliding groove 10 is opened at the bottom side of the inner pipe wall of the diversion tube 6. The outer wall of the sliding frame 72 is fitted to the groove wall of the sliding groove 10, and the inner pipe wall of the diversion tube 6 is aligned with the inner pipe wall of the telescopic tube 71.

[0036] In this embodiment, the sliding groove 10 is provided for installing the sliding frame 72, enabling the telescopic tube 71 to move downward following the electric telescopic rods 74, thereby extending the extension direction of the bottom nozzle of the telescopic tube 71, further increasing the diffusion area of the air outlet of the air conditioner. At the same time, since the inner pipe wall of the diversion tube 6 is aligned with the inner pipe wall of the telescopic tube 71, when the air discharged from the air conditioner enters the interior of the telescopic tube 71 through the diversion tube 6, the air flow path is relatively smooth, thus reducing the resistance to the air and achieving an energy-saving effect.

[0037] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, the driving turntable 8 includes a driving motor 81. The driving motor 81 is inserted at the center of the upper end of the air conditioner housing 1. A rotating disk 82 is provided at the top end of the driving motor 81. An installation cavity 83 is opened inside the rotating disk 82. A plurality of positioning grooves 84 are opened on the side wall of the rotating disk 82. Driving teeth 85 are provided inside the positioning grooves 84. A locking mechanism 86 is provided inside the installation cavity 83.

[0038] In this embodiment, the driving motor 81 is provided to control the rotation of the rotating disk 82. The positioning groove 84 is provided for installing the driving gear 85, and a spring connected to the inner wall of the installation cavity 83 is arranged on the top side of the driving gear 85. When not affected by the locking mechanism 86, the driving gear 85 will retract into the interior of the installation cavity 83. When the driving gear 85 is needed, the driving gear 85 is pushed out by the locking mechanism 86, so that the driving gear 85 meshes with the transmission tooth groove 9. Furthermore, through the meshing setting of the driving gear 85 and the transmission tooth groove 9, during the rotation of the rotating disk 82, the effect of controlling the rotation of the installation cylinder frame 3 is achieved, thereby achieving the effect of controlling the orientation of the flow dividing cylinder 5, so as to achieve the effect of controlling the angles of the diversion pipe 6 and the diffusion mechanism 7, enabling the diffusion mechanisms 7 at various positions to face the same direction simultaneously, so as to achieve the effect of improving the cooling efficiency of a certain place, and after the temperature drops, reducing the power of the air conditioner to achieve the effect of energy conservation and emission reduction.

[0039] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, the locking mechanism 86 includes a fixed shaft rod 861. Electric push rods 862 are arranged at positions on the outer side wall of the fixed shaft rod 861 corresponding to the four installation cylinder frames 3. A limit push block 863 is arranged at one end of the electric push rod 862 away from the fixed shaft rod 861. An installation bridge 864 is arranged at the top end of the fixed shaft rod 861, and both ends of the installation bridge 864 are fixedly connected to the air conditioner box body 1.

[0040] In this embodiment, the fixed shaft rod 861 is provided for installing the electric push rod 862, and the electric push rod 862 is provided for controlling the limit push block 863 to push out the limit push block 863. Since the outer peripheral side of the limit push block 863 is arc-shaped, the driving gear 85 at the position corresponding to the limit push block 863 will be pushed out of the positioning groove 84. And because the position of the limit push block 863 corresponds to the position of the installation cylinder frame 3, the driving gear 85 at the position of the rotating disk 82 corresponding to the limit push block 863 will be pushed out and meshed with the transmission tooth groove 9. When the electric push rod 862 is in a contracted state, the limit push block 863 will not affect the driving gear 85. Therefore, the driving gear 85 will be retracted into the interior of the installation cavity 83 under the influence of the spring and will not mesh with the transmission tooth groove 9. Therefore, the installation cylinder frames 3 at different positions can be driven synchronously or individually, thereby achieving the effect of controlling the orientations of the flow dividing cylinders 5 at various positions.

[0041] In a further preferred embodiment of the present utility model, as Figures 1-6 shown, a hydraulic telescopic rod 11 is arranged inside the installation cylinder frame 3, and both ends of the hydraulic telescopic rod 11 are fixedly connected to the inner wall of the installation cylinder frame 3 and the side wall of the flow dividing cylinder 5 respectively.

[0042] In this embodiment, the hydraulic telescopic rod 11 is provided to control the downward extension distance of the mounting cylinder frame 3, so as to further increase the extension length of the diffusion mechanism 7, achieve the effect of increasing the extension range of the diffusion mechanism 7, thereby achieve the effect of increasing the diffusion range of the air conditioner, achieve the effect of increasing the cooling efficiency, and then after the temperature is completely reduced, achieve the energy-saving effect by reducing the power of the air conditioner.

[0043] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
