Embodiment
Below, by referring to accompanying drawing, embodiments of the invention are described in detail.
Fig. 3 is the side sectional view of the example representing Linearkompressor of the present invention.
According to an example of Linearkompressor of the present invention, as shown in Figure 3, comprising cylinder 200, piston 300 and linear electric machine 400 as in the seal container 110 in airtight space, this linear electric machine 400 comprises inner stator 420, external stator 440 and permanent magnet 460, if permanent magnet 460 carries out straight reciprocating motion by mutual electromagnetic force between inner stator 420 and external stator 440,300, the piston be connected with permanent magnet 460 together can carry out straight reciprocating motion with permanent magnet 460.
Inner stator 420 is fixed on the periphery of cylinder 200, external stator 440 is axially fixed by framework 520 and motor cover 540, framework 520 and motor cover 540 are undertaken being connected by the such as connected element such as screw and are be combined with each other, and thus, fix external stator 440 between framework 520 and motor cover 540.Framework 520 can form as one with cylinder 200, and, can also manufacture separately with cylinder 200 and combine with cylinder 200.In embodiment in figure 3, illustrate the example that framework 520 forms as one with cylinder 200.
The rear of piston 300 is connected with support 320.Four front main springs 800 support two ends by support 320 and motor cover 540.Further, four rear main springs 800 support two ends by support 320 and bonnet 560, and bonnet 560 is combined in the rear of motor cover 540.At the rear of piston 300, there is suction silencer 700, noise when flowing into refrigeration agent to reduce suction refrigeration agent by suction silencer 700 to piston 300.
The inside of piston 300 is hollow morphology, compresses to make the refrigeration agent flowed into by suction silencer 700 flow into the compression volume P be formed between cylinder 200 and piston 300.The front end of piston 300 is provided with suction valve 610, and suction valve 610 is open, and to make refrigeration agent flow into from piston 300 to compression volume P, and the front end of closed piston 300, flow into piston 300 to prevent refrigeration agent again from compression volume P.
If in compression volume P, more than predetermined pressure to carry out compressed refrigerant by piston 300, the expulsion valve 620 being positioned at the front end of cylinder 200 can open.Expulsion valve 620 is arranged on the inner side of the support cap 640 being fixed on cylinder 200 one end, to obtain elastic support by spiral helicine expulsion valve spring 630.The refrigeration agent of the high pressure that have compressed, by being formed at after the hole supporting cap 640 is discharged to and discharges in cap 660, being discharged to the outside of Linearkompressor 100 by loop pipe L, thus is circulated at refrigeration cycle.
The all parts of above-mentioned Linearkompressor 100 in the assembled state, is supported by front support spring 120 and posterior support spring 140, and separates with the bottom surface of seal container 110.Because above-mentioned all parts does not directly contact with the bottom surface of seal container 110, the vibration thus produced on all parts of compressor 100 during compressed refrigerant can not directly be passed to seal container 110.Therefore, it is possible to the vibration reduced because of the vibration of transmitting to the outside of housing 100 and seal container 110 and the noise that produces.
Above-mentioned Linearkompressor, content is as explained in the prior art such, in order to reduce vibration, needs to optimize vibration transmissibility, and needs to limit the design of loop pipe L as the factor likely having influence on efficiency.Certainly, because the body comprising cylinder 200, piston 300 and linear electric machine 400 obtains elastic support in the inside of seal container 110 by supported spring 120,140 and loop pipe L, the vibration of thus transmitting to seal container 110 can regard the excitation force of supported spring 120,140 and the excitation force sum of loop pipe L as.But in the present invention, the excitation force of setting loop pipe L, makes it have and reduces the vibration of transmitting to whole compressor with side's phase place in the opposite direction of the excitation force of supported spring 120,140.
Fig. 4 is the chart of the vibration displacement representing the loop pipe being applied to Linearkompressor of the present invention.
As shown in Figure 4, Linearkompressor of the present invention, in order to reduce vibration by reversal of phase, the natural frequency f of setting loop pipe
lplower than specified operating frequency f.Now, as shown in the chart, although at the natural frequency f lower than loop pipe
lpfrequency in, loop pipe along (+) direction vibration, but, at the natural frequency f higher than loop pipe
lpfrequency in, loop pipe vibrates along (-) direction.Therefore, if specified operating frequency f is higher than the natural frequency f of loop pipe
lp, the vibration of loop pipe then carries out reversal of phase, and the excitation force of loop pipe works along the direction contrary with the excitation force of supported spring, reduces the vibration of transmitting to whole seal container thus.
Further, directly operated by specified operating frequency f when starting, to prevent the breakage of loop pipe.Now, when starting linear electric machine, if from 0 scanning (sweep) to specified operating frequency f, operating frequency before reaching specified operating frequency f then with the natural frequency f of loop pipe
lpunanimously, because resonance phenomenon causes loop pipe to be subject to breakage, thus when starting linear electric machine, advantageous applications is directly carried out the variable-frequency motor operated by specified operating frequency f.
As an example, specified operating frequency f is set as 60Hz, is directly operated by specified operating frequency f when starting, the natural frequency f of loop pipe
lpbelow the 50Hz lower than specified operating frequency f can be set as.
Fig. 5 is the chart of the magnitude of vibrations representing the seal container that the natural frequency based on loop pipe in Linearkompressor of the present invention changes.
As Fig. 5 of the experimental result of Linearkompressor of the present invention, illustrate and specified operating frequency is set as 60Hz, and detected the vibration of transmitting to Integral sealing container by the natural frequency changing loop pipe.
As shown in Figure 5, along with the natural frequency f of loop pipe
lpclose to the 60Hz as specified operating frequency f, the vibration of transmitting to whole seal container will become large, sets the natural frequency f of loop pipe in the frequency domain lower than the 60Hz as specified operating frequency f
lpreduce the vibration of transmitting to whole seal container.
More specifically, if by the natural frequency f of loop pipe
lpchange to 35 ~ 50Hz, the vibration of seal container then can increase to 13 ~ 57Gal, but, based on the natural frequency changes delta f of loop pipe
lpthe vibration changes delta f of seal container very micro-, thus can regard the vibration-stable interval of transmitting to compressor as.But, if by the natural frequency f of loop pipe
lpchange to 50 ~ 60Hz, the vibration of seal container then can increase to 57 ~ 1120Gal, and, based on the natural frequency changes delta f of loop pipe
lpthe vibration changes delta f of seal container comparatively large, thus can regard the interval that the vibration of transmitting to compressor increases as.Further, if by the natural frequency f of loop pipe
lpchange to 60 ~ 70Hz, the vibration of seal container then can be reduced to 1120 ~ 452Gal, but, based on the natural frequency changes delta f of loop pipe
lpthe vibration changes delta f of seal container compare above-mentioned vibration to increase interval change less, even if the vibration values in fact transmitted to seal container reduces, the vibration values comparing above-mentioned vibration stable region also wants large.Further, if by the natural frequency f of loop pipe
lpchange to more than 70Hz, the vibration of seal container then can be reduced to below 452Gal, but, based on the natural frequency changes delta f of loop pipe
lpthe vibration changes delta f of seal container compare vibration to increase interval change less, as foregoing, even if the vibration values in fact transmitted to seal container reduces, the vibration values comparing above-mentioned vibration stable region also wants large.
Therefore, in view of the vibration of integrating compressor, preferably, be in the compressor of 60Hz at specified operating frequency f, the natural frequency f of loop pipe
lpset in the frequency domain of below 50Hz.Further, as mentioned above, in view of with specified operating frequency f in direct ratio determine the natural frequency f of loop pipe
lpproblem, preferably, be in the compressor of 50Hz at specified operating frequency f, the natural frequency f of loop pipe
lpset in the frequency domain of below 41.6Hz.
Above, the present invention is based on embodiments of the invention and accompanying drawing, illustrate and be illustrated in detail.But scope of the present invention is not limited to above each embodiment and accompanying drawing, scope of the present invention should be considered as only limiting according to content described in described claims.
