Referring to figs. 1 through Fig. 3, damping device one embodiment of the air-conditioner outdoor unit of the present invention is applied in frequency conversion
On air-conditioner, being arranged between the off-premises station 1 of transducer air conditioning and mounting platform 3, off-premises station 1 includes room
Outer machine fuselage and off-premises station footing, off-premises station footing stretches out the outdoor unit main body of off-premises station 1, off-premises station footing
It is positioned at the bottom of described outdoor unit main body, it is preferred that described off-premises station footing and described outdoor unit main body are one
Body.Described off-premises station footing is provided with fixing hole, and damping device 2 is nested on described off-premises station footing, makes
With expansion bolt, off-premises station 1, damping device 2 and mounting platform 3 are fixed；As support means, install flat
Platform 3 is alternatively installing rack.
Damping device 2 includes that pedestal 24 and elastic component, pedestal 24 are made of plastics, and described elastic component is by rubber
Glue material is made；Being provided with groove on pedestal 24, the sidewall of described groove is provided with keeps away an opening, described elasticity
Part embeds in the groove of pedestal 24, and described off-premises station footing extend into described groove from a described opening of keeping away,
Described off-premises station footing is placed on described elastic component；Described elastic component includes basis callosity 21 and adnexa callosity,
Described additional callosity be placed in basis callosity 21 bottom, described elastic component also can only include basis callosity 21 or
Described additional callosity；
Being provided through its first through hole 26 on the callosity 21 of basis, basis callosity 21 is hollow box-like, base
The sidewall of plinth callosity 21 is provided with opening, basis callosity be hollow box-like time, the quantity of the first through hole 26 will
Being two, the centrage of two the first through holes 26 is point-blank；Basis callosity 21 is the most solid,
Its circular in cross-section, semicircle or square；
The bottom of described groove is provided with the second through hole (not shown), and described second through hole runs through pedestal 24, the
The centrage of the centrage of one through hole 26 and described second through hole is point-blank, it is preferred that described recessed
Described second through hole that arranges of trench bottom is provided with hollow locating dowel 25, the hollow space of hollow locating dowel 25 with
Described second through hole UNICOM, hollow locating dowel 25 runs through the first through hole 26 of basis callosity 21.Further,
Hollow locating dowel 25 is one-body molded with pedestal 24.
Described additional callosity embeds in described groove, is placed in the bottom of basis callosity 21, the additional leg in Fig. 3
Pad quantity is two, the respectively first additional callosity 22 and the second additional callosity 23, the first additional callosity 22
With the second additional rounded body of callosity 23, semicircular bodies or square body, it is possible to for other shape, first adds
Callosity 22 and the second additional callosity 23 are provided with third through-hole 27, and the centrage of third through-hole 27 and first leads to
Point-blank, hollow locating dowel 25 also extends through third through-hole 27 to the centrage in hole 26.Preferably, subtract
At least provided with a basic callosity 21 on shake device 2, or it is provided with a basic callosity 21 and two or more
Described adnexa callosity, described additional callosity overlays the bottom of basis callosity 21.
Damping device in above example, serves isolation off-premises station 1 and is delivered to shaking on mounting platform 3
Dynamic and the effect of noise, and padded off-premises station 1, make to leave between off-premises station 1 and mounting platform 3 enough
Space draw drainage pipeline, prevention off-premises station drain pipe ice blocks up the various problems of generation.
The height of elastic component is by basis callosity 21 and/or the height of first additional callosity the 22, second additional callosity 23
Degree determines, in the case of different bodies of wall, different outer machine quality, difference troublesome frequencies, and elastic component total
The most also can be different, elastic component needs reasonable in design as vibrating isolation system, attenuation rate, and elastic component height is the biggest
Time, off-premises station 1 is unstable；When elastic component height is the least, damping device does not has due decay effect of vibration.
When the height of design flexibility part, can obtain according to below equation:
Wherein, L is the height of elastic component, and m is the quality of off-premises station, f0For troublesome frequencies, E is elastic
Modulus, S is the sectional area of elastic component.
During design flexibility part, it is preferred that the height of basis callosity 21 is fixed, can be selected for minimum wanting
Seek the height highly determining basis callosity 21, when the highly desirable change of elastic component, can be additional by increasing
The quantity of callosity realizes increasing the height of elastic component, and the quantity of additional callosity does not limits, and only need to reach design needs
The height of the elastic component wanted.
When installing damping device, comprise the steps: 1, select permeability frequency；2, off-premises station is determined
Quality；3, determine the height of elastic component according to Fig. 4, determine basis callosity and/or the number of plies of additional callosity；4、
Through location spiral shell in the basic callosity determined from the through hole of pedestal, step 3 and/or additional callosity through hole
Bolt；5, off-premises station footing being placed on elastic component, bolt is through the through hole on off-premises station footing；6、
By bolt, damping device is fixed in off-premises station footing and support means, is supported for installing and puts down
Platform or installing rack.
As a example by a basic callosity 21 in embodiment and the damping device of two additional callosities 22,23,
It is arranged between air-conditioner outdoor unit 1 and mounting platform 3, and basis callosity 21, additional callosity 22,23 play
The effect of obvious vibration and noise reducing, wherein, in indoor same position noise testing before and after installing damping device
Contrast experiment's such as following table:
| Frequency (Hz) | Add noise (dB) before damping device | Add noise (dB) after damping device |
| 75 | 37 | 20 |
| 80 | 35.5 | 33 |
| 85 | 35 | 27 |
| 90 | 26 | 22.5 |
After seeing of can will be apparent from of upper table installs the damping device of the present embodiment additional, air-conditioner runs at high frequency
Time noise reduction obvious.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for this area
Those of ordinary skill for, without departing from the inventive concept of the premise, it is also possible to make some deformation and
Improving, these broadly fall into protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be with appended
Claim is as the criterion.
