Problems solved by technology

In this way, by disposing the spacer between the stator of the electric element and the airtight container, the electromagnetic vibration of the electric element is transmitted to the airtight container through the spacer. Therefore, compared with the case where the electric element is in direct contact with the airtight container, it is possible to suppress the vibration. transfer effect, but not fully

Embodiment 1

[0060] figure 1 It is a vertical side view of a compressor to which an embodiment of the present invention is applied. The compressor 1 is an internal high-pressure type scroll compressor, and constitutes a known refrigerant circuit connected to a condenser, a decompression device, and an evaporator not shown. The scroll compressor 1 includes: a vertical cylindrical airtight container 2 made of steel plates; a scroll compression element 10 driven by a rotating shaft 22 that is accommodated in the upper part of the inner space of the airtight container 2; Electric element 20 below element 10.

[0061]Airtight container 2 comprises: container main body 4, and its bottom is oil storage part 6, and accommodates electric element 20 (electric motor) and scroll compression element 10; The mode installation of roughly bowl-shaped bottom 4B, it is installed with the mode of closing the bottom opening of this container main body 4. Moreover, a circular mounting hole not shown is form...

Embodiment 2

[0091] In addition, in the above-mentioned first embodiment, by providing the notch 65 around the upper portion of the spacer 60 on the airtight container 2 side, the area of ​​the spacer 60 in contact with the container body 4 of the airtight container 2 is formed to be larger than the area of ​​the spacer 60 in contact with the stator 23 . area is small, but the invention is not limited thereto, for example, as Figure 5 As shown, the area of ​​the spacer 70 in contact with the container body 4 of the airtight container 2 may be formed smaller than the area of ​​the spacer 70 in contact with the stator 23 by providing a cutout 75 around the lower portion of the surface of the spacer 70 on the airtight container 2 side. .

[0092] Figure 5 The shown cutout 75 is formed over the entire circumference on the surface (outer peripheral surface) of the spacer 70 on the airtight container 2 side, similarly to the cutout 65 in the first embodiment. The slit 65 of the first embodim...

Embodiment 3

[0098] Figure 6 It is a vertical side view of a scroll compressor to which another embodiment of the present invention is applied. exist Figure 6 , marked with the above Figure 1 to Figure 5 Components with the same symbols have the same or similar effects or functions, and descriptions are omitted here. Figure 6 Shown at 80 is the spacer of this embodiment. The dimension of the spacer 80 in the axial direction of the rotating shaft 22 is formed to be the same as the dimension of the stator 23 in the axial direction of the rotating shaft 22 . That is, the upper end of the stator 23 is substantially on the same plane as the upper end of the spacer 80 , and the lower end of the stator 23 is substantially on the same plane as the lower end of the spacer 80 .

[0099] In addition, similarly to the above-described respective embodiments, the inner peripheral surface (the surface on the stator 23 side) of the spacer 80 is not provided with notches, unevenness, and the like a...

Abstract

The present invention provides a compressor, capable of eliminating electromagnetic vibration of an electric component from transmitting to a closed container to the utmost so as to reduce vibration and noise of the compressor. The compressor (1) comprises an eddy compression component(compression component) (10) accepted in the closed container (2) and the electric component (20) for driving the compression component (10), the electric component (20) including a stator (23) formed by laminating multiple electromagnetic steel plates; a rotor (25) fixed on a rotating shaft (22) that drives the compression component (10) and rotating on an inner side of the stator (23), the stator (23) being fixed in the closed container spacing a distance piece (60), and an area of the distance piece (60) contacted with the closed container being less than that of the stator.

Description

technical field [0001] The present invention relates to a compressor including a compression element and an electric element for driving the compression element in an airtight container. Background technique [0002] Conventionally, this type of compressor includes a cylindrical airtight container, a compression element and an electric element accommodated in the airtight container. The electric element includes: a stator fixed on the inner surface of the airtight container; and a rotor fixed on the rotating shaft driving the compression element and rotatably provided on the inner surface of the stator. [0003] The stator includes a stack of annular electromagnetic steel sheets and stator coils wound around the teeth of the stack, and is fixed by annular welding or shrink fitting along the inner peripheral surface of the space of the airtight container. [0004] In this type of compressor, electromagnetic vibration is transmitted to the airtight container by the operation ...
