1. A horizontal type rotary compressor, comprising:
a case configured to store oil, and including an inlet and an outlet;
a compressor having a compression space in which refrigerant introduced from the inlet is accommodated;
a driver disposed at a first side of the compressor and configured to drive the compressor;
a rotating shaft configured to penetrate the compressor and connect the driver and the compressor;
an oil feed pipe disposed at a second side of the compressor, and having a first end of the oil feed pipe connected to the rotating shaft and a second end of the oil feed pipe disposed adjacent with a lower surface of the case such that the second end of the oil feed pipe is submerged in oil;
a first plate configured to divide an inside of the case into a first area in which the driver is disposed, and a second area in which the compressor is disposed, the first plate including:
a discharge hole through which a compressed refrigerant is discharged from the compressor to the first area, and
a first hole formed at an upper side of the first plate, through which the compressed refrigerant flows from the first area to the second area; and
a second plate configured to divide the inside of the case into the second area and a third area in which the oil feed pipe is disposed and which communicates with the outlet, the second plate including:
a second hole formed at an upper side of the second plate, through which the compressed refrigerant flows from the second area to the third area,
wherein a lower end of the first plate and a lower end of the second plate are spaced apart from the lower surface of the case to form an oil flow path along the lower surface of the case extending from the first area and under the first plate to the second area, and extending from the second area and under the second plate to the third area.
 
15. A home appliance configured to adjust temperature through heat exchange with an outside using a refrigerant, the home appliance comprising:
a horizontal type rotary compressor configured to compress the refrigerant, wherein the horizontal type rotary compressor includes:
a case configured to store oil, and including an inlet and an outlet,
a compression device configured to compress refrigerant introduced from the inlet,
a driver disposed at a first side of the compression device and configured to drive the compression device,
a first plate configured to divide an inside of the case into a first area in which the driver is disposed, and a second area in which the compression device is disposed, the first plate including:
a discharge hole through which compressed refrigerant is discharged from the compression device to the first area, and
a first hole formed at an upper side of the first plate, through which the compressed refrigerant flows from the first area to the second area, and
a second plate dividing to divide the inside of the case into the second area and a third area which communicates with the outlet, and the second plate including:
a second hole formed at an upper side of the second plate, through which the compressed refrigerant flows from the second area to the third area,
wherein a lower end of the first plate and a lower end of the second plate are spaced apart from the lower surface of the case to form an oil flow path along the lower surface of the case extending from the first area and under the first plate to the second area, and extending from the second area and under the second plate to the third area.
