Vertical type compressor and laundry treating apparatus having the same

A laundry treating apparatus, comprising:

• a cabinet;
• a drum rotatably arranged inside the cabinet to accommodate clothing and having heated air provided thereto to dry the accommodated clothing;
• and
• a compressor located between a bottom surface of the cabinet and the drum on the bottom surface of the cabinet, wherein the compress or comprising:
• a driving motor comprising a stator in which a stator coil is wound around a stator core, a rotor rotatably arranged on an inner circumferential side of the stator, and a rotary shaft coupled to the rotor to rotate together with rotor;
• a compression unit arranged at one side of the driving motor and comprising at least one compression portion which compresses a refrigerant while being operated by a driving force transmitted through the rotary shaft;
• and
• a casing comprising a middle shell formed in a cylindrical shape and a cap inserted into an opening end of the middle shell to be coupled to the middle shell, wherein the middle shell comprises:
• a body portion accommodating the driving motor and the compression unit therein;
• and
• a cap insertion portion arranged at one end of the body portion such that the cap is inserted thereinto, and expanded in a radial direction of the rotary shaft, wherein an insulator is located between the stator core facing the cap and the stator coil on a section of the stator core in an axial direction, wherein at least a portion of the insulator overlaps the cap insertion portion in the radial direction of the rotary shaft, and wherein a height from an upper end of the stator core facing the cap in the axial direction to an upper end of the insulator is formed higher than or equal to a height from the upper end of the stator core to a lower end of the cap insertion portion and/or a height from the upper end of the stator core to the opening end of the cap inserted into the cap insertion portion.

A vertical type compressor, comprising:

• a driving motor comprising a stator in which a stator coil is wound around a stator core, a rotor rotatably arranged on an inner circumferential side of the stator, and a rotary shaft coupled to the rotor to rotate together with rotor;
• a compression unit arranged at one side of the driving motor and comprising at least one compression portion which compresses a refrigerant while being operated by a driving force transmitted through the rotary shaft;
• and
• a casing comprising a middle shell formed in a cylindrical shape and a cap inserted into an opening end of the middle shell to be coupled to the middle shell, wherein the middle shell comprises:
• a body portion accommodating the driving motor and the compression unit therein;
• and
• a cap insertion portion arranged at one end of the body portion such that the cap is inserted thereinto, and expanded in a radial direction of the rotary shaft, wherein the middle shell has both open ends in an axial direction, a first cap and a second cap are respectively inserted into both the ends of the middle shell in the axial direction to be coupled to the middle shell, and a refrigerant discharge pipe is coupled to the first cap to communicate with an internal space of the casing, and wherein an inner diameter of the first cap is formed larger than an inner diameter of the second cap.
