Abstract
An air filter device for an air-conditioning apparatus includes a mounting frame unit, an axle mounted rotatably to the mounting frame unit, and a plurality of blade-like frames mounted axially on and projecting radially from a peripheral surface of the axle. The blade-like frames are spaced angularly apart from one another. A plurality of filtering sheets are held respectively by the blade-like frames. Each of the filtering sheets covers an entire area confined by a respective one of the blade-like frames. The filtering sheet includes active carbon fabric felt which is made by weaving activated carbon fiber filaments.

An air filter device for an air-conditioning apparatus, comprising:
- a mounting frame unit;
- an axle mounted rotatably to said mounting frame unit;
- a plurality of blade-shaped frames mounted axially on and projecting radially from a peripheral surface of said axle, said frames being spaced angularly apart form one another;
- and
- a plurality of filtering sheets held respectively by said frames, each of said filtering sheets covering an entire area defined by a respective one of said frames;
- said axle having several axially extending dovetail grooves formed in said peripheral surface thereof and spaced angularly apart from one another, each of said dovetail grooves having first and second end portions which open respectively in first and second end surfaces of said axle;
- each of said frames having retaining means for removably engaging a respective one of said dovetail grooves for retaining said frames on said axle.
An air filter device for an air-conditioning apparatus, comprising:
- a mounting frame unit including vertically oriented left and right frames spaced horizontally apart from each other and horizontally oriented upper and lower frames detachably interconnecting upper and lower ends of said left and right frames;
- an axle rotatably mounted to said mounting frame unit and having left and right end portions respectively journalled in said left and right frames of said mounting frame unit, said axle further including left and right internally splined holes respectively formed in end surfaces of said left and right end portions thereof and extending a predetermined distance into said axle;
- said mounting frame unit including a right externally splined shaft rotatably mounted on an inner face of said right frame to engage said right internally splined hole of said axle, and a rotary member removably and rotatably mounted on an inner face of said left frame, said rotary member having a left externally splined shaft projecting from and along an axis of rotation of said rotary member toward said right externally splined shaft, said left externally splined shaft being engageable with said left internally splined hole of said axle for rotatably carrying said axle between said left and right frames;
- a plurality of blade-shaped frames mounted axially on and projecting radially from a peripheral surface of said axle, said frames being spaced angularly apart form one another;
- and
- a plurality of filtering sheets held respectively by said frames, each of said filtering sheets covering an entire area defined by a respective one of said frames.
