The present invention is used in an air conditioner, the magnetic repulsion type two-stage compressor configured to form an electromagnet inside the cylinder and to form a disk-shaped piston as a permanent magnet, so as to compress the refrigerant using magnetic repulsion by the power source. will be.

In general, a compressor used in an air conditioner is composed of a compression device for compressing gas in a sealed container and a driving device for supplying power for compression. The compressor is reciprocated, rotary, scrolled, etc. according to the compression method and the driving method. Are classified. In general, the compression device is driven by a motor, the compressor driven by the motor drive is rotated integrally with the rotor of the motor to transmit the rotational force to the compression unit, the bearing for supporting the rotating shaft, the piston operated by the rotating shaft, Cylinders forming the working space of the piston, valves for controlling the flow of gas sucked into or discharged from the cylinder, suction pipes and discharge pipes through which the gas flows, suction mufflers and discharge mufflers to reduce the noise of the flowing gas Consists of

In the compressor configured as described above, when the power is applied, the motor drives the piston of the compression device to suck the refrigerant gas of low temperature and low pressure, compress the gas into high temperature and high pressure gas, and supply it to the air conditioner through the discharge port and the discharge muffler.

Such a compressor operates a compression device by converting electrical energy into mechanical work by a driving unit, which is a driving device. The compressor has a disadvantage in that the structure is complicated, noise is generated during operation, and energy loss is increased in the energy conversion process.

The purpose of the present invention is to form an electromagnet inside the cylinder and to form a disk-shaped piston as a permanent magnet, by using a repulsive force to compress the refrigerant by the power source, simplifying the structure and reducing noise, efficiency It is to provide a magnetic repulsion two stage compressor which improves.

Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.

The present invention, as shown in FIG. 1 and FIG. 2, inlet and outlet ports are formed on one side and the other side of the periphery, and the connecting pipes (11a, 11b) are connected to the inlet and outlet ports, and the upper cylinder and the lower cylinder are The cell 10 to be formed, the electromagnets 20 respectively fixed to the upper end, the lower end and the middle part of the inside of the cell 10, and the inner top and bottom of the cell 10 passing through the center of the electromagnet 20. Guide shafts 30 fixed to the surface, and the disks 40 are slidably inserted into the upper and lower portions of the guide shaft 30 and the outer periphery is hermetically adhered to the inner circumferential surface of the cell 10 and formed of permanent magnets. The construction is a basic feature of the technical construction.

Here, the cell 10 has a first suction opening 12a and a second suction opening 12b formed at one lower side thereof, and a first discharge opening 13a and a second discharge opening 13b formed at the other lower side thereof, The third discharge port 13c and the fourth discharge port 13d are formed, and the third suction port 12c and the fourth suction port 12d are formed on the other side. In addition, the suction pipe 14 is connected to the first suction opening 12a and the second suction opening 12b, and the connection pipe 11b is connected to the first discharge opening 13a and the fourth suction opening 13d, and the second discharge opening is provided. The connection pipe 11a is connected to 13b and the 3rd suction port 12c, and the discharge pipe 15 is connected to the 3rd discharge port 13c and the 4th discharge port 13d. On the other hand, each suction port is opened only inward, and each discharge port is equipped with a check valve 16 to open only outward.

In addition, the disk 40 is formed of a permanent magnet has a compression ring 41 is formed in the center and the outer circumference, and slidably inserted into the inner circumferential surface and the outer peripheral surface of the guide shaft 30 of the cell 10 to perform the function of a piston Done.

On the other hand, the electromagnet 20 and the disk 40, as shown in Figure 3 and 4, the phase of the AC power supply to the electromagnet 20 of the upper, the electromagnet 20 of the middle and the electromagnet 20 of the lower It is supplied by being offset by 180 degrees, and the upper disk 40 and the lower disk 40 are also configured such that the poles of the magnets are arranged.

When the power is applied to the electromagnet 20, the present invention configured as described above causes the upper disk 40 and the lower disk 40 formed of permanent magnets to be repulsed or attracted by polarity as the polarity of the electromagnet is changed, Reciprocating operation. Therefore, when the disk 40 is moved upward, the first suction port 12a, the third suction port 12c, the second discharge port 13b, and the fourth discharge port 13d are closed by the check valve 16, and The second suction port 12b, the fourth suction port 12d, the first discharge port 13a, and the third discharge port 13c are opened, and the lower cylinder sucks refrigerant gas into the lower portion and the refrigerant gas in the upper portion connects the connecting pipe 11b. It is transferred to the lower portion of the upper cylinder through the upper cylinder, the refrigerant gas is introduced into the lower portion of the upper refrigerant gas is discharged through the discharge pipe (15). In addition, when the disk 40 is moved downward, each inlet and outlet are reversely opened and closed by the check valve 16, the lower cylinder is the refrigerant gas is sucked into the upper portion and the lower refrigerant gas through the connecting pipe (11a) The upper cylinder is transferred to the upper cylinder, and the refrigerant gas is introduced into the upper cylinder, and the lower refrigerant gas is discharged to the discharge tube 15. Therefore, the refrigerant gas is continuously sucked into the suction pipe 14 by the continuous operation and the refrigerant gas is discharged into the discharge pipe 15.

The present invention is the driving unit and the compression unit is integrated, so that the power is directly applied to the electromagnet, the structure is simple, less vibration and noise, the energy loss of the compressor is reduced and the efficiency is improved. In addition, by varying the frequency applied to each electromagnet, the reciprocating cycle can be changed to operate as an inverter-type compressor that varies the capacity of the compressor in response to the load of the air conditioner.

As described above, the present invention forms an electromagnet inside the cylinder and forms a disk-shaped piston as a permanent magnet, thereby compressing the refrigerant using magnetic repulsion by the power source, thereby simplifying the structure and reducing noise. It is very useful for improving efficiency.
