Abstract

A deodorizer is constructed of a casing defining an intake opening and a discharge opening, a blower provided in opposition to the intake opening, a filter provided in the flow passage of an air stream to be produced by the blower, and a reservoir for storing an odor-absorbing liquid therein. The blower, filter, and reservoir are all housed within the casing.

Claims

1. A deodorizer comprising:

(a) a casing containing an air intake opening, an air discharge opening, and a reservoir inserting opening;

(b) a blower disposed in said casing in opposition to said air intake opening so as to create an air stream from said air intake opening to said air discharge opening;

(c) a reservoir which, in use, contains an aqueous odor-absorbing liquid;

(d) a filter composed of a flattened drum-like container having through-holes therethrough and containing non-hygroscopic fibers, said filter being rotatably mounted in said reservoir such that, in use, an upper portion of said filter is in the air stream produced by said blower and a lower portion of said filter extends into said reservoir, said reservoir and said filter comprising an assembly detachably operatively mounted in said casing;

(e) a motor disposed in said casing and detachably operatively connected to said filter, said motor serving, when operatively connected to said filter, to rotate said filter about an at least substantially horizontal axis automatically and continuously; and

(f) a plate integral with said reservoir and positioned so as to close said reservoir inserting opening when said assembly is detachably operatively mounted in said casing.

2. A deodorizer as recited in claim 1 wherein said non-hygroscopic fibers are glass wool.

3. A deodorizer as recited in claim 1 and further comprising means for detachably securing said plate to said casing.
