Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to an outdoor unit of an air conditioner. BACKGROUND

[0002] At present, an outdoor unit of an air conditioner generally comprises a casing, a fan, a compressor and a heat exchanger. The core components such as the compressor and the fan will generate high-frequency mechanical vibration when running. If the compressor is in rigid contact with the casing, the vibration will be transmitted to the indoor through the casing and the building structure, forming noise, and even possibly causing structural fatigue.

[0003] In the prior art, a damping foot pad is usually installed to slow down the vibration. The traditional rubber passive damping stiffness and damping are not adjustable, which can only work effectively in a specific frequency band, and the working frequency (i.e. the natural frequency) of the damping device itself cannot be adjusted. Therefore, when the external working conditions change, the damping device will lose its excellent damping performance, and sometimes even cause new resonance peaks in the coupled system.

[0004] Due to the vibration characteristics of the air conditioning system, such as multiple excitation sources, strong coupling and wide frequency band, the traditional rubber passive damping scheme has been difficult to meet the increasingly stringent vibration control requirements. Therefore, in the prior art, the structure of the damping foot pad cannot well meet the requirements of the outdoor unit of the air conditioner, and many problems are easily caused, resulting in poor user experience.

[0083] In some embodiments, the air conditioner outdoor unit comprises a heat exchanger, the heat exchanger is located inside the shell and is used to exchange heat for the air passing through it.

[0084] In some embodiments, the heat exchanger is placed on the bottom plate.

[0085] In some embodiments, the air conditioner outdoor unit comprises a fan, the fan is located inside the casing, the fan is located on one side of the heat exchanger, and the fan is used to introduce air outside the casing into the casing through the air inlet of the casing and to deliver air inside the casing to the outside of the casing through the air outlet of the casing by the operation of the fan, so as to realize the circulation of air.

[0086] In some embodiments, the air conditioner outdoor unit comprises a compressor, the compressor is located inside the casing, and the compressor is used to drive the flow of refrigerant.

[0087] In the prior art, a damping device 100 is usually arranged between the compressor and the bottom plate to reduce the vibration between the compressor and the bottom plate. In the damping device 100, the damping and the stiffness parameters are important factors affecting the damping performance. The conventional damping device 100 is usually composed of rubber, and the stiffness and damping of the conventional damping device 100 cannot be adjusted, that is, the conventional damping device 100 cannot adjust its working frequency, so it can only work effectively in a specific frequency band for the structure to be damped. When the external working condition changes, the conventional damping device 100 may not only fail, but also may cause a new resonance peak in the coupled system. The vibration working condition in the air conditioner outdoor unit has the characteristics of multiple excitation sources, strong coupling and wide frequency band. The conventional damping device 100 obviously cannot meet the actual demand, and is easy to cause poor damping effect, large noise generation and other adverse conditions.

[0088] Based on this, a damping device 100 capable of adjusting its stiffness and damping size according to the actual working condition demand is arranged in the present application, so as to meet the needs of users.

[0089] In some embodiments, the air conditioner outdoor unit comprises a damping device 100, the damping device 100 is arranged between the bottom plate and the compressor, and the damping device 100 is used to reduce the vibration amplitude of the compressor on the bottom plate. By adjusting the stiffness and damping of the damping device 100, the vibration of the compressor in different frequency environments can be buffered, so as to reduce the amplitude of the bottom plate vibration, avoid generating more noise, and reduce the user experience.

[0090] In some embodiments, referring to Figure 1 and Figure 2 , the damping device 100 comprises a cylinder body 200, one end of the cylinder body 200 is connected to the bottom plate, and the cylinder body 200 is used to accommodate damping liquid. The damping liquid converts mechanical energy into heat energy to dissipate energy during vibration, and realizes the functions of damping amplitude reduction and frequency adjustment through its viscoelastic characteristics.

[0091] In some embodiments, referring to Figures 2-6The damping device 100 comprises a partition 300 which is slidingly connected inside the cylinder 200, the partition 300 has a first through hole 301, the partition 300 divides the inside of the cylinder 200 into a first chamber and a second chamber, the first chamber is located on the side of the partition 300 away from the bottom plate, the second chamber is located on the side of the partition 300 close to the bottom plate, and the first chamber and the second chamber both contain damping liquid.

[0092] In some embodiments, the partition 300 and the cylinder 200 have a gap therebetween, which can be used for damping liquid to pass through, so as to realize the flow of the damping liquid between the first chamber and the second chamber.

[0093] In some embodiments, referring to Figure 5 The damping device 100 comprises an adjusting plate 400 which is attached to the side of the partition 300 away from the bottom plate, and the adjusting plate 400 has a second through hole 401. By changing the position of the adjusting plate 400, the overlapping area between the first through hole 301 and the second through hole 401 can be changed. When the first through hole 301 and the second through hole 401 are in communication, the flow of the damping liquid through the first chamber and the second chamber becomes larger, and the resistance that the partition 300 and the piston rod 500 experience when moving inside the cylinder 200 becomes smaller, so as to realize the damping reduction of the damping device 100; when the first through hole 301 and the second through hole 401 are in complete non-communication, the damping liquid only flows through the gap between the partition 300 and the cylinder 200, and the resistance that the partition 300 and the piston rod 500 experience when moving inside the cylinder 200 becomes larger, so as to realize the damping increase of the damping device 100.

[0094] In some embodiments, the damping device 100 comprises a piston rod 500 which is arranged in and slidingly connected to the cylinder 200, one end of the piston rod 500 is connected to the side of the compressor close to the bottom plate, the other end of the piston rod 500 is connected to the adjusting plate 400, and the piston rod 500 can drive the adjusting plate 400 to rotate, so as to make the second through hole 401 and the first through hole 301 communicate.

[0095] In some embodiments, referring to Figure 2 and Figure 4 The damping device 100 comprises a first elastic member 600 which is arranged inside the cylinder 200, and the first elastic member 600 is used to push the partition 300 to move towards the compressor, that is, when the compressor moves towards the bottom plate, the piston rod 500 moves axially along the cylinder 200 towards the bottom plate, at this time the first elastic member 600 is compressed, and the first elastic member 600 and the end of the piston rod 500 generate a reaction force, when the compressor moves away from the bottom plate, the first elastic member 600 pushes the piston rod 500 to move towards the compressor, so as to make the piston rod 500 return to the initial position or even higher than the initial position, so as to realize the damping effect of the vibration device next time.

[0096] Through the above scheme, by setting the damping device 100 between the compressor and the bottom plate, when the compressor is in a low-frequency vibration state, the piston rod 500 drives the partition 300 to move in the cylinder 200, the space of the first chamber and the second chamber changes, at this time the first through hole 301 and the second through hole 401 do not coincide completely, the damping liquid only flows between the first chamber and the second chamber through the gap between the partition 300 and the inner wall of the cylinder 200, at this time the damping is in a large damping state; when the compressor is in a medium-high frequency vibration state, the damping needs to be reduced, by rotating the piston rod 500 to make the adjusting plate 400 rotate, when the overlapping area of the first through hole 301 and the second through hole 401 gradually increases, at this time the damping not only flows through the gap between the partition 300 and the inner wall of the cylinder 200, but also flows through the overlapping part of the first through hole 301 and the second through hole 401, the damping flow rate increases to realize the damping reduction of the damping device 100, to meet the working condition of the compressor.

[0097] In some embodiments, the peripheral wall of the partition 300 can be tightly attached to the inner wall of the cylinder 200, so that the damping liquid only passes through the channel generated between the first through hole 301 and the second through hole 401, by rotating the adjusting plate 400, the overlapping area of the first through hole 301 and the second through hole 401 changes, to realize the change of the damping liquid capacity in the first chamber and the second chamber, thereby changing the damping size in the damping device 100.

[0098] In some embodiments, the first elastic member 600 can be selected from a spring, the axis of the spring is located on the same straight line as the axis of the cylinder 200, the spring has the ability of elastic deformation, and the spring structure is simple and has high reliability, can bear axial pressure, and accurately control the movement track, so that when the piston rod 500 moves to the bottom of the cylinder 200 and compresses the spring, the spring can move the piston rod axially to the initial position along the original track, to facilitate the next damping operation.

[0099] In some embodiments, the first elastic member 600 includes but is not limited to a spring piece, a rubber block, a leaf spring, etc.

[0100] In some embodiments, referring to Figure 6 and Figure 9The piston rod 500 includes a piston column 501 connected with the baffle 300, and includes a rotating tube 502 fixedly connected with the adjusting plate 400, which is sleeved and rotationally connected with the piston column 501. When the compressor is in a medium-high frequency state, the rotating tube 502 is rotated by the worker to rotate the adjusting plate 400, so that the overlapping area of the first through hole 301 and the second through hole 401 gradually increases, the flow of the damping liquid between the first chamber and the second chamber increases, and the damping is reduced. When the first through hole 301 and the second through hole 401 are completely overlapped, the damping is in a minimum state.

[0101] In some embodiments, the piston rod 500 includes a sleeve 503 sleeved on the rotating tube 502 to increase the sealing performance of the connection between the piston rod 500 and the cylinder body 200.

[0102] In some embodiments, referring to Figure 7 and Figure 8 , the shortest distance between the axis of the first through hole 301 and the axis of the piston rod 500 is the same as the shortest distance between the second through hole 401 and the axis of the piston rod 500, so that when the piston rod 500 rotates to drive the adjusting plate 400 to rotate, the overlapping area of the first through hole 301 and the second through hole 401 is the area of the first through hole 301 or the second through hole 401, thereby further increasing the upper limit of the flow between the first chamber and the second chamber, and further increasing the threshold of the damping size of the damping device 100.

[0103] In some embodiments, the first through hole 301 is provided in plurality, and the second through hole 401 is provided in the same number and one-to-one correspondence with the first through hole 301.

[0104] In some embodiments, the first through hole 301 and the second through hole 401 are each provided in three around the axis of the cylinder body 200, and the area of the first through hole 301 and the area of the second through hole 401 are equal, so as to further increase the total overlapping area of the first through hole 301 and the second through hole 401, thereby increasing the flow between the first through hole 301 and the second through hole 401.

[0105] In some embodiments, referring to Figure 2 and Figure 10, the one end of the cylinder body 200 towards the compressor is provided with a mounting groove 701, the damping device 100 comprises a sleeve 800, the sleeve 800 is slidingly connected to the mounting groove 701; the damping device 100 comprises an abutting assembly 700, the abutting assembly 700 is connected with the piston rod 500, the abutting assembly 700 is located outside the cylinder body 200, and the abutting assembly 700 is used for contacting and driving the sleeve 800 to slide in the mounting groove 701. Through the cooperation of the sleeve 800 and the abutting assembly 700, when the piston rod 500 moves in the axial direction, at this time, the sliding friction force between the sleeve 800 and the mounting groove 701 is generated, which is equivalent to dry friction damping, so that the damping size of the damping device 100 is further increased, and the actual working condition requirement of the compressor is met.

[0106] In some embodiments, with reference to Figures 2-6 , the damping device 100 comprises a second elastic member 702, the second elastic member 702 is arranged in the mounting groove 701, the second elastic member 702 is located at the end of the sleeve 800 away from the abutting assembly 700, and the second elastic member 702 is used for pushing the sleeve 800 to move towards the abutting assembly 700, and the second elastic member 702 can be selected from a spring. Through the arrangement of the second elastic member 702, when the piston rod 500 drives the sleeve 800 to move to the second elastic member 702 in the direction of the second elastic member 702 until the end wall of the sleeve 800 abuts against the second elastic member 702, the second elastic member 702 is compressed to generate elastic deformation, and an opposite force is applied to the sleeve 800, so that the pressure on both ends of the piston rod 500 is increased, thereby increasing the stiffness of the damping device 100 to meet the actual use requirement.

[0107] In some embodiments, in order to increase the universality of the damping device 100, the damping device 100 can be used in devices of different sizes and models, and the stiffness performance of the damping device 100 as a whole can be increased through the cooperation of the abutting assembly 700, the sleeve 800 and the second elastic member 702, therefore, the abutting assembly 700 comprises a mounting cylinder 703, the mounting cylinder 703 is arranged at the end of the piston rod 500 located outside the cylinder body 200, the piston rod 500 is arranged at the axial center of the mounting cylinder 703 and is fixedly connected with the mounting cylinder 703; the abutting assembly 700 comprises an abutting cylinder 704, the abutting cylinder 704 is arranged in the mounting cylinder 703, the abutting cylinder 704 can move towards or away from the cylinder body 200, and the abutting cylinder 704 can lock the relative position with the mounting cylinder 703.

[0108] Through the above technical scheme, by operating the abutting cylinder 704, the distance between the two ends of the abutting cylinder 704 and the mounting cylinder 703 is increased, so that the abutting cylinder 704 can move with the piston rod 500 and abut against the sleeve 800, so as to push the sleeve 800 to generate dry friction force between the sleeve 800 and the groove wall of the mounting groove 701, and at the same time, the second elastic member 702 is compressed, thereby increasing the stiffness of the damping device 100.

[0109] In some embodiments, the mounting cylinder 703 is sleeved on the abutting cylinder 704.

[0114] Through the above technical solution, when the length of the abutting assembly 700 needs to be increased according to the distance between the compressor and the bottom plate, the worker rotates the abutting cylinder 704, so that the positioning block moves from the first positioning groove to the second positioning groove, and the abutting cylinder 704 is moved towards the cylinder body 200, so that the positioning block slides in the second positioning groove to the communication position of the second positioning groove and the third positioning groove, and then the abutting cylinder 704 is rotated again, so that the positioning block moves to the third positioning groove, thereby fixing the relative position of the abutting cylinder 704 and the mounting cylinder 703.
