Embodiment 1

[0020] Such as figure 1 As shown, the scroll compressor is driven by the drive motor 1 . The transmission mechanism includes a crankshaft 2, an eccentric wheel 4 and a bearing 8. The compression mechanism includes a movable scroll 10 and a fixed scroll 15 which engage with each other to enclose a plurality of compression chambers 27 . The middle end of the crankshaft 2 stretches out a crank 3 at a position deviated from the center of the crankshaft, and the crank 3 is inserted into the hole 5 of the eccentric wheel 4 . The bearing 8 and the bushing 11 on the back side of the movable scroll 10 are installed successively outside the eccentric wheel 4 . The middle part of the housing 20 is fixed with a bracket 21, and the crankshaft 3 is supported by the bearing 26 in the middle hole of the bracket 21 to rotate. The crank 3 drives the movable scroll 10 to rotate eccentrically. The end surface 22 is opposite to the end plate 16 of the movable scroll 10 and can support the end p...

Embodiment 2

[0025] image 3 The example shown with the figure 1 , 2 The same parts in the illustrated embodiment are omitted, and the same reference numerals are given to the parts that perform the same functions for description.

[0026] The difference with embodiment 1 is the structure of the valve, such as image 3 As shown, the valve includes a valve housing 46 fixed in the crankshaft 2, the seat 41, spring 42, armature 43, and valve core 44 are sequentially installed in the valve housing 46, the seat 41 is fixed with the valve housing 46, and the valve housing 46 and A valve hole 50 runs through the axial channels 6 , and when the valve core 44 closes the valve hole 50 , the axial channel 6 is closed. The valve casing 46 is made of magnetically permeable material, which can increase the magnetic force of the armature 43 .

[0027] When shutting down, the coil 49 of the solenoid is energized, the solenoid attracts the armature 43, and the armature 43 drives the spool 44 to open th...

Embodiment 3

[0030] Figure 4 The example shown with the image 3 The same parts in the illustrated embodiment are omitted, and the same reference numerals are given to the parts that perform the same functions for description.

[0031] The difference between embodiment 3 and embodiment 2 is that there is an iron core 47 inside the valve seat 41, and the iron core 47 is close to the solenoid. When the solenoid is energized, the iron core 47 is excited. A spring 42 is provided between the iron core 47 and the armature 43 , and the armature 43 is fixedly connected with the valve core 44 .

[0032] When shutting down, the coil 49 of the solenoid is energized, the solenoid attracts the armature 43, and the armature 43 drives the spool 44 to open the axial passage 6, so that the back pressure chamber 31 communicates with the low pressure chamber 28, and the pressure in the back pressure chamber 31 is obtained. freed. After the pressure in the back pressure chamber 31 is reduced, the movable ...

Abstract

The invention aims to provide a scroll compressor and a restarting method thereof and the scroll compressor is used for solving the problem that an existing scroll compressor is difficult to restart in short time. The scroll compressor comprises a low-pressure chamber, a compression chamber and a back pressure chamber, wherein the low-pressure chamber is used for sucking a low-pressure refrigerating agent, the compression chamber is used for sucking the low-pressure refrigerating agent from the low-pressure chamber and is formed by meshing a static vortex disc with a moving vortex disc, and the back pressure chamber is used for receiving a high-pressure refrigerating agent discharged from the compression chamber and is arranged on the backside of the moving vortex disc. The scroll compressor is characterized by further comprising a channel and a valve, wherein the low-pressure chamber is communicated with the back pressure chamber by virtue of the channel, and the valve is used for controlling the opening and closing of the channel; the channel and the valve are arranged in a crankshaft capable of driving the moving vortex disc to rotate, and the valve is arranged at one end, close to a shell of the scroll compressor, of the crankshaft.

Description

technical field [0001] The invention relates to a scroll compressor, which comprises a low-pressure chamber for absorbing low-pressure refrigerant, a compression chamber formed by meshing a fixed scroll and a movable scroll for drawing refrigerant from the low-pressure chamber, and receiving high-pressure refrigerant discharged from the compression chamber. The high pressure chamber and the back pressure chamber set on the back side of the static scroll. Background technique [0002] The back of the movable scroll of the scroll compressor is often provided with a back pressure chamber. During the operation of the compressor, the high-pressure gas in the back pressure chamber pushes the movable scroll to the fixed scroll, so that the meshing end surfaces between the movable scroll and the fixed scroll are in close contact, and the internal leakage between the compression chambers is reduced. [0003] The current scroll compressor has the problem of difficulty in restarting w...
