AI Technical Summary

Benefits of technology

The present invention is a motor-operated compressor that can make the compressor smaller and lighter by eliminating a bearing from the frame. This reduces the length and weight of the frame.

Problems solved by technology

However, it is difficult to form the oil supply passage in the scroll or frame, and also the oil supply passage becomes long.
If the oil supply passage becomes long, oil is not quickly supplied when the compressor is turned on, thereby causing a frictional loss.
However, costs and operation noise increase due to the ball bearing and a weight of the compressor increases due to a weight of the ball bearing.

Embodiment Construction

[0048]Description will now be given in detail of a motor operated compressor according to exemplary embodiments disclosed herein, with reference to the accompanying drawings.

[0049]FIG. 1 is a sectional view illustrating an inside of a motor operated compressor in accordance with the present invention.

[0050]As illustrated in FIG. 1, a low-pressure motor operated scroll compressor (hereinafter, abbreviated as motor operated compressor) according to an embodiment of the present invention includes a frame 102 fixed to an inside of a compressor casing (hereinafter, abbreviated as a casing) 101, a driving motor 103 serving as a motor unit provided at one side of the frame 102 based on the frame 102, and a compression unit 105 provided at another side of the frame 102 to compress a refrigerant using a rotational force of the driving motor 103.

[0051]As the casing 101 is arranged in a generally horizontal direction with respect to the ground, the driving motor 103 and the compression unit 10...

Abstract

A motor operated compressor according to the present invention has a driving motor having a stator and a rotor. A rotation shaft of the motor is coupled to the rotor. The compressor also has a frame, a fixed scroll positioned on one side of the frame, and an orbiting scroll supported on the frame and positioned between the fixed scroll and the frame. The fixed scroll forms a compression chamber together with the orbiting scroll. The driving motor, the fixed scroll, the orbiting scroll, and the frame are positioned within a casing of the compressor. The rotation shaft rotatably passes through the fixed scroll and the frame and is to eccentrically coupled to the orbiting scroll, allowing the orbiting scroll to perform an orbiting motion relative to the fixed scroll. One end portion of the rotation shaft is supported by the fixed scroll while the other end is supported by the casing.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]Pursuant to 35U.S.C. § 119(a), this application claims the benefit of an earlier filing date of and the right of priority to Korean Application No. 10-2018-0041124, filed on Apr. 9, 2018, the contents of which are incorporated by reference herein in their entirety.BACKGROUND OF THE DISCLOSURE1. Field of the Disclosure[0002]The present invention relates to a motor operated compressor operated by a motor.2. Background Art[0003]A motor operated compressor mainly employs a scroll compression method suitable for a high compression ratio operation among various compression methods. In the scroll type motor operated compressor, a motor unit configured as a rotary motor is installed in a hermetic casing, and a compression unit configured by a fixed scroll and an orbiting scroll is disposed at one side of the motor unit. The motor unit and the compression unit are connected to each other by a rotation shaft so that a rotational force of the motor u...
