Abstract
The invention discloses a compressor damping structure of a ceiling air conditioner outdoor unit. The compressor damping structure comprises a compressor body, a support plate and a baseplate. The support plate is arranged on the baseplate. The compressor body is installed on the support plate. Compressor pins are arranged at the bottom of the compressor body and connected with the support plate. First springs are arranged between the compressor pins and the support plate. The compressor pings are connected with but do not directly make contact with the support plate and indirectly make contact with the support plate through the first springs, so that the situation that vibration of the compressor body is directly transmitted to the support plate is avoided; the first springs can absorb and buffer most vibration generated by the compressor body, and energy of vibration is converted into other types of energy; point contact between the compressor body and the baseplate is changed into area contact through the support plate, so that the damping function is effectively achieved; and the degree of freedom of the compressor body is increased through the first springs, and use of the compressor body is facilitated.
Description
Technical field
The present invention relates to a kind of compressor vibration-proof structure of the outer machine of air-conditioning equipment field, more particularly to ceiling type air conditioner.
Background technology
The noise of the outer machine of traditional air conditioner is big, needs, installed in the behaviour area for being located away from people, even to need sometimes independent
Equipment room is provided to outdoor machine of air-conditioner so that air-conditioning is installed and occupies big quantity space between floors, as current Urban Land Price is general
All over very high, air-conditioning using when the more situation that takes up space seriously increased the living cost of people.
The main cause that outdoor machine of air-conditioner noise is produced is that the vibration that compressor is produced is delivered to chassis, existing solution
Mainly using compressor producer, rubber damper is carried, this vibration-proof structure can be used in the relatively low occasion of noise requirements,
But, the vibration of compressor can not be completely cut off completely for this rubber blanket of powerful compressor, so cannot accomplish completely
Vibration transmission between isolation compressor and machine chassis, when the vibration of compressor is delivered to the sheet metal structural on chassis, easily
Cause the resonance of sheet metal structural.Especially for frequency converter sets, the vibration characteristics of compressor changes with frequency and changes, compressor
The energy transmission of vibration causes the probability of panel beating resonance bigger to machine case, and had a strong impact on outdoor machine of air-conditioner uses peace
Entirely.

Specific embodiment
Technical scheme is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
As Figure 1-5, the compressor vibration-proof structure of the outer machine of a kind of ceiling type air conditioner, including compressor body 1, gripper shoe 3
And chassis, gripper shoe 3 is connected with chassis, compressor body 1 is in gripper shoe 3, and the bottom of compressor body 1 is provided with compressor
Foot 101, compression under-chassis 101 is connected with gripper shoe 3, is provided with the first spring 4 between compression under-chassis 101 and gripper shoe 3.
Between compression under-chassis 101 and gripper shoe 3, the first spring 4 is set, although compression under-chassis 101 is connected with gripper shoe 3
But not directly contact, but indirectly contacted by the first spring 4.The vibration for so avoiding compressor body 1 is direct
It is delivered in gripper shoe 3, and the first spring 4 can absorbs the major part with the generation of buffer compression body 1 due to the characteristic of itself
Vibration, the kinetic energy that vibration is had is converted to other energy, effectively can subtract eventually through the vibration that gripper shoe 3 is delivered on chassis
Few, and the contact between compressor body 1 and chassis is changed into from a contact by face contact by gripper shoe 3, more effectively reach
Vibration-damping function.By arrange the first spring 4 also add 1 degree of freedom of compressor body, be more convenient for compressor body 1 installation and
Use.
Damping block 5 is provided between first spring 4 and gripper shoe 3.
In order to further effectiveness in vibration suppression be realized, between the first spring 4 and gripper shoe 3, damping block 5 is set, by the first spring
Force way between 4 and gripper shoe 3 is that face stress, stable force way increased effectiveness in vibration suppression by a stress check calculation.
Multiple rubber blankets 6 are provided between damping block 5 and gripper shoe 3, and multiple rubber blankets 6 with the geometric center of gripper shoe 3 are
Center is symmetric.
Specifically, rubber blanket 6, when vibrating effect is delivered on rubber blanket 6, rubber are set between damping block 5 and gripper shoe 3
Rubber cushion 6 plays a part of damping vibration attenuation, and the kinetic energy that vibration is had is converted to heat energy, is that the vibration damping of compressor body 1 provides one
Kind new mode, multiple rubber blankets 6 are symmetric, and increased overall steadiness and symmetry, it is to avoid because of asymmetric product
Raw vibration.The number of rubber blanket 6 is preferably six, so to reach optimal structural stability.
Division board 7 is provided between chassis and gripper shoe 3.
In order to the vibration for producing compressor body 1 is completely isolated with chassis, the vibration for not allowing compressor body 1 produce is to chassis
Transmission, is provided with division board 7, the object for consisting of some flexible materials of division board 7 between chassis and gripper shoe 3.
Specifically, division board 7 is selected the composite molding plate being made up of felt and butyl rubber.
In order to reach optimal isolation effect, dieplate that division board 7 is defined as being made up of felt and butyl rubber, no
