The specific embodiment
Compressor (30) is compressed into the high temp/high pressure state with the gas medium of the low temperature/low pressure of suction.This compressor (30) is arranged on the inside of Machine Room, and the Machine Room is arranged on the bottom, back of refrigerator; This compressor (30) can produce very big noise and vibration at work.Above-mentioned compressor (30) is arranged on inside, Machine Room, the operating noise that can absorb compressor (30) and the structure of vibration need be set.
As shown in Figure 4, the chassis (32) that is formed at the bottom surface, Machine Room is provided with the support (34) that projects upwards, and the outer peripheral face of support (34) inserts installs vibrationproof ball (36), and vibrationproof ball (36) is made by elastic material, plays the effect that absorbs vibration.
The bottom of above-mentioned compressor (30) has fixed head (38), and fixed head (38) makes the installation of compressor (30) and chassis (32) easy.This fixed head (38) is fixed on the upper end of support (34).Be connected with the pipe arrangement (40) of coming in and going out for medium in the side of compressor (30).
As shown in Figure 4, the left side of above-mentioned compressor (30) has sealed tube (42), and sealed tube (42) is used for filled media in compressor.By the freeze cycle structure filled media of sealed tube (42) to refrigerator, this medium mainly adopts flammable medium (for example, R600A etc.).
After refrigerator refrigeration loop structure filled media, seal sealed tube (42) by sealed tube (42) with ultrasonic welder (44).Below seal process is described.At first, with sealed tube (42) be clipped in compressor (30) near, with above-mentioned clamping operation simultaneously, by ultrasonic welder (44) sealed tube (42) is carried out the seal welding operation.
