The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
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 are positioned at compressor body 20 bottoms and are fixedly connected with it; Installing plate 10 is positioned on the sidewall of compressor body 20 with the pad A of compressor body 20.Relative prior art, pad A is positioned on the sidewall, improved the welding position, the height that is the center of gravity phase butt welding contact A of compressor body reduces, thereby reduced the tilting moment of compressor body 20, change the vibrations of compressor body 20 generations by the transfer function of installing plate 10 to miscellaneous part, thereby reduce the noise that vibration of compressor causes.
Shown in Fig. 5 a and 5b, installing plate 10 has upwardly extending wall 12, the sidewall welding of the top of wall 12 and compressor body 20, the height of wall 12 has determined the height that pad A pad A ' relatively of the prior art improves, as required, can further optimize the height of wall 12, fall low noise effect thereby improve.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 tops are provided with welded plate 13, and welded plate 13 is curved, cooperate with the cylindrical side wall of compressor body 20, by welded plate 13 sidewall with compressor body 20, improve welding strong and welding quality.
More preferably, be provided with the pre-punching of welding position 13a on the welded plate 13, when a plurality of installing plates 10 and compressor body 20 welding, each installing plate 10 all rushes a 13a welding in advance according to the welding on the welded plate 13, thereby guarantee that all installing plate 10 welding are unified, welding and assembling height is consistent, improves welding precision.The pre-punching of welding position is preferably 4-6, and the sheet metal thickness of installing plate 10 is 1.5-3mm preferably.
Installing plate 10 also comprises and is 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 welds with sidewall, each installing plate 10 arranges two walls 12 and sidewall welding, improve weld strength and welding stability, guarantee welding quality, the width of base plate 11 is that the distance between two installing plates 10 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 bolt 31 is damping washer fixedly, thereby compressor body 20 is fixed on the air-conditioning base plate 30 by installing plate 10.
Of the present inventionly also provide a kind of air-conditioner, comprised 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 the sidewall, and h2 has been improved in the position of pad relatively of the prior art, preferably, the height of h2 is 20-40mm, and in the present embodiment, h2 is 30mm, equivalently, stress point (pad A) 30mm that descended is supported at the center of compressor body 20 relatively, and the resistance to capsizing of compressor strengthens, and has improved compressor operating and stability in transit.
The distance of centroidal distance support point reduces, optimized from compressor body 20 to installing plate 10 to damping washer to bolt 31 transfer functions to air-conditioning base plate 30 and this whole process of casing for air conditioner, effectively reduced the exciter response of outdoor machine of air-conditioner at 600-800Hz, make the response under its unit exciting force, become only have original
Thereby realize the purpose of significantly damping noise reduction.
In addition, owing to cancelled former installation board of compressor, make the compressor lowest part become lower cover by former installing plate, like this under the prerequisite that guarantees 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 find out, the position of compressor body 20 in the air-conditioner h3 that can descend again, one ground, h3 is 5-8mm, further the center of gravity of compressor body is reduced, improve effect of vibration and noise reduction, strengthened the cloth pipeline for again compressor top, wiring and the cotton space of bag sound insulation, and these measures have further promoted damping noise reduction.The inside air-conditioning of outdoor machine of air-conditioner has obtained release, makes stringing wiring bag sound insulation cotton etc. all than front aspect, and the favourable produced on-site efficient that improves the workman can prevent from also that pipeline from running foul of each other to have guaranteed the reliability of air-conditioning.
Because after adopting installing plate of the present invention, the damping noise reduction effect is very good, so that available removing plays the damping block that the damping noise reduction effect is adopted on the former air-conditioning system, has reduced system material cost and cost of labor.
Compressor of the present invention adopts new installing plate, cuts off to a certain extent compressor noise Vibration propagation path, and experimental results shows that noise reduction has obtained important breakthrough, and the refrigeration data are fully qualified and far below enterprise's mark requirement.Concrete experimental data sees the following form 1 and table 2.
Be respectively the noise repetition measurement result of the air-conditioning system of prior art and compressor of the present invention such as table 1 and table 2.In the prior art shown in the table 1 in the noise repetition measurement result data of the air-conditioning system of compressor, in the refrigeration situation total value surpass 58 decibels have 3 not conform to lattice point, peak value surpass 49 decibels have 20 not conform to lattice point (specifically do not conform to lattice point and see Table middle italic band underscore).In the noise repetition measurement result data of the air-conditioning system of the compressor of the present invention shown in the table 2, the experimental data of contrast table 1 can be added up and be drawn, positive total value decline 1-3 decibel, front peak value decline 1-12.8 decibel, side total value decline 2-8 decibel; The side peak value 2-16.5 decibel that generally descends.On experimental data, adopt compressor and the air-conditioning system of new installing plate, determined obvious effect at the reduction noise, none does not conform to lattice point integral body.
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 have realized following technique effect:
According to compressor of the present invention and have its air-conditioner, the pad of installing plate and compressor body is positioned on the sidewall of compressor body, relative prior art, improved the welding position, the height that is the center of gravity phase butt welding contact of compressor body reduces, thereby reduced the tilting moment of compressor body, changed the vibrations of compressor body generation by the transfer function of installing plate to miscellaneous part, thereby reduce the noise that vibration of compressor causes.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and 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 modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
