DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application.

[0019] With reference to Figures 1-6 An energy-saving central air conditioner comprises a shell 1, which is a basic supporting component of the entire energy-saving central air conditioner and has good structural stability. It provides a solid installation foundation for the internal components and can effectively resist the influence of the external environment to ensure stable operation of the air conditioner under various complex working conditions. The shell 1 is fixedly connected with an expansion frame 2, which can reasonably expand the internal space layout of the air conditioner and provide space for installation of a heat dissipation plate 4. The expansion frame 2 is fixedly connected with a stop ring 3 inside, which is a supporting component and can provide accurate positioning for the heat dissipation plate 4 to ensure that the heat dissipation plate 4 maintains a stable position during installation and use, avoiding the influence of shaking or displacement on the heat dissipation effect and the normal operation of other components. The expansion frame 2 is provided with the heat dissipation plate 4, which effectively reduces the temperature inside the outdoor unit of the air conditioner and improves the operating efficiency and service life of the outdoor unit. A pair of pull handles 41 are fixedly connected to the side wall of the heat dissipation plate 4 away from the stop ring 3, which facilitates the installation, disassembly and maintenance operation of the heat dissipation plate 4 by the staff and improves the operability and maintainability of the outdoor unit. The heat dissipation plate 4 is in contact with the stop ring 3, and a protection frame 5 is fixedly connected to the vertical outer side wall of the expansion frame 2. The protection frame 5 fixedly connected to the vertical outer side wall of the expansion frame 2 mainly plays a protection role and can prevent external objects from colliding with and damaging the stop block 51 and other components. The expansion frame 2 is horizontally slidably connected with the stop block 51, and the stop block 51 is in contact with the heat dissipation plate 4. The arrangement of the stop block 51 enables the heat dissipation plate 4 to be stably installed inside the expansion frame 2, and the end of the stop block 51 away from the protection frame 5 is circularly arranged to ensure that when the heat dissipation plate 4 is horizontally taken out, the heat dissipation plate 4 can drive the stop block 51 to move horizontally towards the protection frame 5.

[0020] Further comprising: An elastic assembly is arranged in the protection frame 5, and the elastic assembly enables the stop block 51 to be in contact with the heat dissipation plate 4 after resetting; An electric lifting assembly is arranged below the shell 1, and the lifting assembly drives the shell 1 to lift.

[0021] The elastic assembly comprises a pair of sliding blocks two 55 arranged in the protection frame 5, and the same telescopic rod one 56 is fixedly connected to the opposite side walls of the two sliding blocks two 55. The spring 57 is sleeved on the telescopic rod one 56, and the two ends of the spring 57 are fixedly connected with the sliding blocks two 55, respectively. Under the elastic force of the spring 57, the stop block 51 is subjected to an external force and quickly and accurately resets to the position in contact with the heat dissipation plate 4 to lock the heat dissipation plate 4.

[0022] The block 51 extends to the protection frame 5, and the block 51 and the protection frame 5 are fixedly connected with a connecting plate 52 at one end, T-shaped sliding grooves 53 are formed in the opposite side walls of the two connecting plates 52, sliding blocks one 54 are horizontally slidably inserted into the T-shaped sliding grooves 53, and the sliding blocks one 54 can smoothly slide in the T-shaped sliding grooves 53, so that subsequent disassembly is facilitated.

[0023] The sliding blocks two 55 are horizontally slidably connected with the T-shaped sliding grooves 53, and a pair of anti-disengagement rods 58 are threadedly connected to the connecting plate 52 and are in contact with the sliding blocks one 54.

[0024] The electric lifting assembly comprises a base 6 arranged below the shell 1, four telescopic rods two 63 are fixedly connected to the top of the base 6, the telescopic rods two 63 are arranged to ensure the force balance of the shell 1 during lifting, thereby ensuring the stability of the shell 1 during lifting.

[0025] The top of the base 6 is fixedly connected with a pair of connecting ears 64, the same bidirectional screw rods 65 are rotatably connected to the opposite side walls of the two connecting ears 64, the bidirectional screw rods 65 are accurately matched with screw blocks 66, and the rotation is converted into linear motion, so that the lifting of the traction rods 68 and the fixed plate 62 is driven.

[0026] The screw blocks 66 are horizontally slidably connected with the base 6, and the connecting ears 64 are fixedly connected with a motor 69 for driving the bidirectional screw rods 65 to rotate.

[0027] The outer expansion frame 2 and the shell 1 are arranged in a through manner, the top of the outer expansion frame 2 is fixedly connected with a water baffle 7, the water baffle 7 can effectively block rainwater, condensed water and other water from entering the inside of the air conditioner outdoor unit, and protect the internal components from water erosion and damage.

[0028] The functions and principles of the present application can be described as follows: Height adjustment: before starting, the base 6 is fixed to the installation position to ensure its horizontal stability; the bidirectional screw rods 65 are driven by the motor 69 to rotate clockwise or counterclockwise, and the two screw blocks 66 are driven by the bidirectional screw rods 65 to slide horizontally along the base 6 and approach or move away from each other.

[0029] When the screw block 66 moves, the traction rod 68 hinged between the vertical lug 67 of the screw block 66 and the vertical lug 67 of the fixed plate 62 tilts to push the fixed plate 62 to vertically ascend or descend through the telescopic rod 63.

[0030] At this time, the fixed plate 62 is connected with the side plate 61 through the screw, and the whole shell 1 is lifted or lowered synchronously to adapt to the space requirement of different installation environments. After adjusting to the target height, the motor 69 is turned off, and the positions of the screw block 66 and the traction rod 68 are locked to ensure the stability of the shell 1.

[0031] The working of the heat dissipation plate 4: when the external machine operates, the airflow is guided through the through design of the external frame 2 and the shell 1, and the heat dissipation plate 4 is tightly attached to the gasket 3 to form a sealed heat dissipation channel, and the heat is quickly conducted out through the surface of the heat dissipation plate 4.

[0032] When the heat dissipation plate 4 needs to be cleaned or maintained: horizontally pull the handle 41 to the outside, and the heat dissipation plate 4 moves away from the gasket 3 and pushes the stop block 51 to slide into the protection frame 5. When the stop block 51 moves, the T-shaped sliding groove 53 of the connecting plate 52 drives the sliding block one 54 and the sliding block two 55 to move to the direction of the telescopic rod one 56, and compresses the spring 57 between the two sliding block twos 55. The spring 57 maintains force balance through the telescopic rod one 56 to ensure the subsequent reset locking of the sliding block one 54, the sliding block two 55 and the stop block 51. When the spring 57 needs to be cleaned or maintained: unscrew the anti-dropping rod 58, horizontally take out the sliding block one 54 from the T-shaped sliding groove 53, and take out the sliding block two 55 together to drive the telescopic rod one 56 and the spring 57 to be taken out, so as to prevent the spring 57 from losing elasticity after long-term use, which reduces the reset locking effect of the stop block 51.

[0033] Waterproof function: the inclined water baffle 7 at the top of the external frame 2 guides the water flow to be discharged along the guide groove 71 in the rain, so as to prevent rainwater from penetrating into the shell 1. The distribution density and the inclination angle of the guide groove 71 match the heat dissipation requirement of the shell 1, which not only guarantees the drainage efficiency, but also does not affect the normal ventilation and heat dissipation. The fixed connection design of the water baffle 7 and the external frame 2 further strengthens the anti-seepage performance.

[0034] Daily operation and reset: after the height adjustment is completed, the side plate 61 and the fixed plate 62 are locked by the screw to maintain the lifting stability. After the heat dissipation maintenance is completed, it is confirmed that the stop block 51 is reset through the spring 57 and is in close contact with the heat dissipation plate 4, and the anti-dropping rod 58 needs to be tightened to be in close contact with the sliding block one 54 to prevent loosening. The lubrication state of the bidirectional screw rod 65 and the flexibility of the hinged point of the traction rod 68 are checked regularly to ensure the durability and reliability of the lifting function.

[0035] The whole use process is realized through the space adaptation of the electric control lifting, the flexible components guarantee the quick disassembly and assembly of the heat dissipation module, the water retaining structure optimizes the environmental adaptability, and finally the dual goals of energy-saving operation and convenient maintenance are achieved.

[0036] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
