Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a compressor damping device, an air conditioning outdoor unit and an air conditioner. Background Art

[0002] The vibration-damping design of the compressor directly affects the noise level generated by the vibration of the air conditioner's outdoor unit. Currently, a vibration-damping rubber pad is typically installed between the compressor and the chassis of the air conditioner's outdoor unit to reduce the compressor's own vibration and the transmission of vibration to the chassis, thereby reducing air conditioning noise and protecting the piping. As the requirements for vibration and noise control in air conditioners increase, two-stage vibration isolation technology is beginning to be applied to compressor vibration isolation.

[0003] The shock-absorbing devices of the existing technology do not provide sufficient overall restraint on the compressor. When the compressor shakes too much during transportation, the top of the compressor is connected to the air-conditioning pipe. Large shaking can easily cause the pipe to break, resulting in damage to the air conditioner and increased equipment costs. Some compressors reduce the shaking of the top of the compressor during transportation by adding temporary fixing devices, but these devices need to be removed when the air conditioner is installed. The structure and operation are complex and inconvenient to use. At the same time, single-stage shock-absorbing devices often avoid excessive displacement when the compressor vibrates by setting a higher stiffness, resulting in a higher natural frequency and easy fixed-frequency resonance when the compressor is running at a low frequency. When multi-stage foot pads are set, the number of upper foot pads is often greater than the lower foot pads, which can easily lead to uneven force on the lower foot pads, causing the compressor to tilt, unstable connection, and poor shock absorption effect. Summary of the Invention

[0004] In order to solve the deficiencies in the prior art, the present invention provides a compressor shock absorbing device, an air conditioner outdoor unit and an air conditioner, which are used to solve the problem of pipeline damage caused by excessive shaking of the compressor during transportation.

[0027] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described in this application are only part of the embodiments of the present invention, not all of them. Based on the spirit of the present invention, other embodiments obtained by ordinary technicians in this field without making creative efforts are all within the scope of protection of the present invention.

[0029] like Figure 1-Figure 5 As shown, embodiment 1 of the present invention discloses a compressor vibration reduction device, which is mainly used for reducing the vibration of a compressor 3 in an air-conditioning outdoor unit 1. The compressor vibration reduction device includes: a fixed bracket 7, an adapter plate 13, a primary vibration reduction pad 18, and a secondary vibration reduction pad 19. The lower end of the fixed bracket 7 is connected to the air-conditioning outdoor unit 1, and the upper end is connected to the adapter plate 13 through multiple primary vibration reduction pads 18. The upper end of the adapter plate 13 is connected to the compressor 3 through multiple secondary vibration reduction pads 19.

[0030] The number of the first-level shock-absorbing pads 18 is greater than or equal to the number of the second-level shock-absorbing pads 19, so that the total vertical stiffness K of the first-level shock-absorbing pads is m Greater than or equal to the total vertical stiffness K of the secondary shock-absorbing pad n .

[0031] The total vertical stiffness K of the first-level shock-absorbing pad m Equal to the number of the first-level shock-absorbing pads 18 multiplied by the vertical stiffness K1 of the first-level shock-absorbing pads, the total vertical stiffness K of the second-level shock-absorbing pads n It is equal to the number of secondary shock-absorbing pads 19 multiplied by the secondary shock-absorbing pad vertical stiffness K2.

[0032] Specifically, the total vertical stiffness K of the first-level shock-absorbing foot pad is m , expressed as follows:

[0033] K m =m×K1

[0034] Where:

[0035] K m is the total vertical stiffness of the first-level shock-absorbing pad;

[0036] m is the number of first-level shock-absorbing pads;

[0037] K1 is the vertical stiffness of the first-level shock-absorbing foot pad, which is obtained through factory parameters.

[0038] At the same time, the total vertical stiffness K of the secondary shock-absorbing pad n , expressed as follows:

[0039] K n =n×K2

[0040] Where:

[0041] K n is the total vertical stiffness of the secondary shock-absorbing pad;

[0042] n is the number of secondary shock-absorbing pads;

[0043] K2 is the vertical stiffness of the secondary shock-absorbing foot pad, which is obtained through factory parameters.

[0044] In a specific embodiment, when the compressor 3 vibrates, the vibration of the compressor 3 is transmitted to the adapter plate 13 after being damped by the secondary damping pad 19, and the vibration of the adapter plate 13 is transmitted to the fixed bracket 7 after being damped by the primary damping pad 18, thereby achieving double damping and greatly improving the damping effect. At the same time, since there is a primary damping pad 18 below the secondary damping pad 19 for double damping and the total vertical stiffness K of the primary damping pad is m Greater than or equal to the total vertical stiffness K of the secondary shock-absorbing pad n , so that the natural frequency of the two-stage shock-absorbing pad can be lower than the natural frequency of the conventional single-stage shock-absorbing device, which is beneficial to avoid resonance with the natural frequency of the compressor during low-frequency operation, effectively reducing the vibration of the compressor 3 during low-frequency operation, and improving the stability of the compressor 3 during vibration. Moreover, the number m of the first-stage shock-absorbing pads is greater than or equal to the number n of the second-stage shock-absorbing pads, avoiding uneven force on the compressor during vibration, which causes the compressor to tilt, thereby improving the connection stability.
