Room odor control

Claim 2

A liquid odor control dispenser comprising a disk impeller of expanded plastic rotating in a compartment having liquid and air inlets near the center of the impeller and outlet ports for vapor air mixtures at the periphery of the disk impeller, said impeller having porous rough surface sides defining parallel planes, and means for supplying said impeller through the liquid inlet adjacent to its center of rotation with liquid, said liquid supply means including a conical housing having a restricted opening at its apex submerged in a stored body of the liquid and an upwardly diverging wall whose upper edge engages said impeller.

Claim 3

The dispenser defined in claim 1 including, means for variably compressing said impeller intermediate said liquid inlet thereto and its periphery including a rotary drive element engaging the upper surface of the impeller, and means interconnecting said drive element and said conical housing to variably clamp said impeller therebetween.

Claim 4

The dispenser defined in claim 1 including needle valve means cooperating with said restricted opening to vary the flow of liquid therethrough, and means interengaging said conical housing and said needle valve means for varying the restricted opening.

Claim 5

The dispenser defined in claim 3 in which actuation of said interengaging means variably compresses said impeller intermediate said liquid inlet and the periphery of said impeller.

Claim 6

The dispenser defined in claim 1 in which said conical housing has internally radially extending walls spiralling upwardly in a direction trailing the direction of rotation of said impeller.

Claim 7

A liquid dispenser for room odor control comprising a housing having upper and lower members with closely spaced walls defining an impeller compartment between them and a motor compartment in the upper member, the upper wall having a central opening between the compartments and said impeller compartment having an air exhaust opening at the periphery thereof, air intake means in the wall of the upper member, a prime mover in the motor compartment having its drive shaft exposed to said impeller compartment through said central one of the openings, an impeller of flexible porous material having rough porous sides mounted on said shaft disposed in said impeller compartment for rotation by the shaft, and means extending through said upper wall for depositing liquid odor control on the impeller adjacent to the center thereof including an opening in close proximity to the impeller and providing access thereto for dispersion of odor control liquid directly into said impeller.

Claim 8

A liquid dispenser for room odor control comprising a housing having upper and lower members with closely spaced walls defining an impeller compartment between them and a motor compartment in the upper member, the upper wall having a central opening between the compartments and said impeller compartment having an air exhaust opening at the periphery thereof, air intake means in the wall of the upper member, a prime mover in the motor compartment having its drive shaft exposed to said impeller compartment through said central one of the openings, an impeller of flexible porous material having rough porous sides mounted on said shaft disposed in said impeller compartment for rotation by the shaft, and means extending through said upper wall for depositing liquid odor control on the impeller adjacent to the center thereof including an opening in close proximity to the impeller and providing access thereto for dispersion of odor control liquid directly into said impeller.

Claim 9

The dispenser defined in claim 6 in which said depositing means includes a liquid storage in one of said members, and liquid conducting means between said liquid storage and said impeller.

Claim 10

A liquid control dispenser comprising, a hollow housing having two shell portions defining a compartment and including wall means supported adjacent the edges of the upper shell defining a space thereabove, a motor supported on the upper shell of the housing in said space, a disk impeller of expanded plastic rotatably carried by the shaft of the motor below the wall means disposed in the compartment and having a porous rough surface on the upper one of two radially extending sides thereof defining parallel planes, said housing having spaced liquiD and air access openings located on said one side of the disk, said wall means being in close proximity to said impeller and defining an air flow opening centrally of the impeller through which air from said air access opening passes in contact with the motor and is confined to pass into engagement with said upper side of the disk, means extending through said wall means and the liquid access opening for applying an odor control composition to said rough surface of the impeller adjacent to its center of rotation for absorption therein, means disposed peripherally of the edge of the impeller including a wall in close proximity thereto and circumferentially spaced vent openings directing and receiving odorized air impelled by the impeller to exhaust it from the housing.

Claim 11

A liquid control dispenser comprising, a hollow housing having two shell portions defining a compartment and including wall means supported adjacent the edges of the upper shell defining a space thereabove, a motor supported on the upper shell of the housing in said space, a disk impeller of expanded plastic rotatably carried by the shaft of the motor below the wall means disposed in the compartment and having a porous rough surface on the upper one of two radially extending sides thereof defining parallel planes, said housing having spaced liquiD and air access openings located on said one side of the disk, said wall means being in close proximity to said impeller and defining an air flow opening centrally of the impeller through which air from said air access opening passes in contact with the motor and is confined to pass into engagement with said upper side of the disk, means extending through said wall means and the liquid access opening for applying an odor control composition to said rough surface of the impeller adjacent to its center of rotation for absorption therein, means disposed peripherally of the edge of the impeller including a wall in close proximity thereto and circumferentially spaced vent openings directing and receiving odorized air impelled by the impeller to exhaust it from the housing.

Claim 12

The dispenser defined in claim 8 in which said housing is readily separable in the plane of the impeller for ready removability of the disk to clean and reinstall it.
