Embodiment approach
[0031] The present invention also intends to solve the following problems.
[0032] (1) Generally, the electric compressor is expected to reduce abnormal vibration and noise generated in the accumulator. However, since there are many causes of abnormal vibration and noise, it is difficult to efficiently reduce the abnormal vibration and noise generated in the accumulator.
[0033] (2) The accumulator has a dual structure of an outer shell (container body) and a suction pipe arranged inside it in terms of its function and properties. In addition, the sources of vibration that vibrate the outer shell of the accumulator (container body) and the suction pipe inside are located at two places, the motor mechanism unit and the compression mechanism unit built in the airtight container. Furthermore, the frequency band of the vibration component generated in the motor mechanism part is different from the frequency band of the vibration component generated in the compression mechanism ...
Embodiment approach 1
[0037]
[0038] Below, refer to Figure 1 to Figure 3 , the configuration of electric compressor 100 according to Embodiment 1 will be described. Here, the electric compressor 100 will be described assuming that it is configured as a hermetic vertical rotary compressor. However, the electric compressor 100 may have a structure other than a hermetic vertical rotary compressor.
[0039] figure 1 It is a cross-sectional view showing the structure of electric compressor 100 according to Embodiment 1. figure 2 and image 3 Each is a cross-sectional view showing the structure of the accumulator 1 used in the electric compressor 100 . figure 2 The cross-sectional structure of the accumulator 1 viewed obliquely from above is shown. image 3 The cross-sectional structure of the accumulator 1 seen from the front direction is shown.
[0040] Such as figure 1 As shown, the electric compressor 100 according to Embodiment 1 includes a compression mechanism unit 6 for compressing ...
Embodiment approach 2
[0078] Below, refer to Image 6 and Figure 7 , the configuration of electric compressor 100A according to Embodiment 2 will be described. Image 6 It is a sectional view showing the structure of an electric compressor 100A according to the second embodiment. Figure 7 It is a sectional view showing the structure of the accumulator 1A used in the electric compressor 100A.
[0079] Such as Image 6 and Figure 7 As shown, it is the same as the electric compressor 100 of Embodiment 1 (refer to figure 1 and figure 2 ) compared with the electric compressor 100A of Embodiment 2 in that it has an accumulator 1A instead of the accumulator 1 . The accumulator 1A is an accumulator in which a supporting member 2 and a shielding member 9 are arranged inside. The shielding member 9 prevents liquid refrigerant (liquid refrigerant) from entering the suction pipe 4 . The liquid refrigerant is supplied to the accumulator 1A from a refrigeration cycle (not shown) through a supply pipe...
