Detailed description of the invention
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 3 and Figure 4, according to compressor of the present invention, comprising: compressor body 20; Installing plate 10, installing plate 10 is positioned at compressor body 20 bottom and is fixedly connected with it; Installing plate 10 is positioned on the sidewall of compressor body 20 with the pad A of compressor body 20.Hinge structure, pad A is positioned on sidewall, improve welding position, the i.e. height reduction of the center of gravity phase butt welding contact A of compressor body, thus reduce the tilting moment of compressor body 20, change the vibrations of compressor body 20 generation by the transfer function of installing plate 10 to miscellaneous part, thus the noise that reduction vibration of compressor causes.
As shown in figure 5a and 5b, installing plate 10 has the wall 12 upwards extended, the top of wall 12 and the sidewall weld of compressor body 20, the height of wall 12 determines the height that the pad A ' in pad A hinge structure improves, as required, further can optimize the height of wall 12, thus improve the effect reducing noise.The height of wall 12 is best at 20-50mm, and its outward appearance is preferably linear pattern or arc line shaped.
Preferably, wall 12 top is provided with welded plate 13, and welded plate 13 is curved, coordinates with the cylindrical side wall of compressor body 20, by the sidewall of welded plate 13 with compressor body 20, improves the strong and welding quality of welding.
More preferably, welded plate 13 is provided with welding and rushes position 13a in advance, when multiple installing plate 10 welds with compressor body 20, each installing plate 10 all rushes a 13a welding in advance according to the welding on welded plate 13, thus ensureing that the welding of all installing plates 10 is unified, welding and assembling height is consistent, improves welding precision.Welding is rushed position in advance and is preferably 4-6, the sheet metal thickness preferably 1.5-3mm of installing plate 10.
Installing plate 10 also comprises in horizontally disposed base plate 11, wall 12 is two, two walls 12 are arranged on base plate 11 two ends symmetrically, the welded plate 13 of two wall 12 upper ends all and sidewall weld, each installing plate 10 arranges two walls 12 and sidewall weld, improve weld strength and welding stability, ensure welding quality, the distance of width that is between two installing plates 10 of base plate 11 is preferably 30-50mm.
The center of base plate 11 is provided with installing hole 11a, and installing hole 11a matches with damping washer, and damping washer fixed by bolt 31, thus is fixed on air-conditioning base plate 30 by installing plate 10 by compressor body 20.
Of the present inventionly additionally provide a kind of air-conditioner, comprise aforesaid compressor, the base plate 11 of the installing plate 10 of compressor is fixed on the base plate 30 of air-conditioner by damping washer and bolt 31.
According to a preferred embodiment of the present invention, as shown in Figures 2 and 3, pad A is positioned on sidewall, and the position of the pad in hinge structure improves h2, preferably, the height of h2 is 20-40mm, and in the present embodiment, h2 is 30mm, equivalently, the center of compressor body 20 supports that stress point (pad A) have dropped 30mm relatively, and the resistance to capsizing of compressor strengthens, and improves compressor operating and stability in transit.
The distance of centroidal distance support point reduces, optimize from compressor body 20 to installing plate 10 to damping washer to bolt 31 to the transfer function of air-conditioning base plate 30 and this whole process of casing for air conditioner, significantly reduce the exciter response of outdoor machine of air-conditioner at 600-800Hz, make the response under its unit exciting force, become only have original
thus realize the object of significantly damping noise reduction.
In addition, owing to eliminating former installation board of compressor, compressor lowest part is made to become lower cover by former installing plate, like this under the prerequisite ensureing the h1 size shown in Fig. 2, as shown in Figure 6 and Figure 7, the mounting structure comparison diagram of compressor of the present invention and compressor of the prior art, availablely to find out, the position of compressor body 20 in air-conditioner can decline again h3, one ground, h3 is 5-8mm, further the center of gravity of compressor body is lowered, improve effect of vibration and noise reduction, increase cloth pipeline to again compressor top, the space of wiring and bag sound insulation cotton, and these measures further facilitate damping noise reduction.The inside air-conditioning of outdoor machine of air-conditioner obtains release, makes stringing bag sound insulation of connecting up cotton etc. all than front aspect, and the favourable produced on-site efficiency of raising workman, also can prevent pipeline from colliding with each other and ensure that the reliability of air-conditioning.
After adopting installing plate of the present invention, damping noise reduction effect is very good, makes availablely to remove the damping block former air-conditioning system playing damping noise reduction effect and adopt, and reduces system material cost and cost of labor.
Compressor of the present invention, adopts new installing plate, and cut off compressor noise Vibration propagation path to a certain extent, experimental results shows that noise reduction achieves important breakthrough, and refrigeration data is completely qualified and mark requirement far below enterprise.Specific experiment data see the following form 1 and table 2.
As table 1 and table 2 are respectively the noise repetition measurement result of the air-conditioning system of prior art and compressor of the present invention.In prior art shown in table 1 air-conditioning system of compressor noise repetition measurement result data in, in refrigeration situation, total value has 3 not conform to lattice point more than 58 decibels, and peak value has 20 not conform to lattice point (specifically not conforming to lattice point in italic band underscore in Table) more than 49 decibels.In the noise repetition measurement result data of the air-conditioning system of the compressor of the present invention shown in table 2, the experimental data of contrast table 1 can be added up and be drawn, front total value decline 1-3 decibel, front peak value decline 1-12.8 decibel, side total value decline 2-8 decibel; Side peak value is decline 2-16.5 decibel generally.From experimental data, adopt compressor and the air-conditioning system of new installing plate, reduction noise determine obvious effect, overall none do not conform to lattice point.
The noise from air conditioner repetition measurement result data table of table 1 prior art
Table two noise from air conditioner repetition measurement of the present invention result data table.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
According to compressor of the present invention and the air-conditioner with it, the pad of installing plate and compressor body is positioned on the sidewall of compressor body, hinge structure, improve welding position, the i.e. height reduction of the center of gravity phase butt welding contact of compressor body, thus reduce the tilting moment of compressor body, change the vibrations of compressor body generation by the transfer function of installing plate to miscellaneous part, thus the noise that reduction vibration of compressor causes.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
