Abstract: The subject invention relates to a fan housing, comprising a unitary molded structure formed from a material that has a flame spread rating of twenty five or less. The unitary molded structure comprises a base, an impeller housing centrally located next to the base, and a flow path located circumferentially around the impeller housing with one or more defined walls for directing air flow. An exhaust port receives air from the flow path and outputs air in a particular direction.

Abstract: There is an ice machine. The machine has i) a cabinet, ii) an icemaker adapted to making ice, iii) a bin situated in the cabinet below the icemaker, (iv) a drawer positioned in the bin. The icemaker is situated in the cabinet. The drawer is substantially non-refrigerated and is adapted to being pulled at least partially out of the cabinet. The drawer has an opening at the top thereof such that ice can be removed directly or indirectly by hand and has a drain therein to allow melt water to drain out.

Abstract: An open top solution supply or recovery tank that is removably mounted on a carpet extractor or wet pickup vacuum cleaner and has a lid that is removably mounted to and seals the top of the tank. A generally U-shaped carry handle is pivotally attached to opposite sides of the tank for carrying the tank. The ends of the carry handle have lid latching member extending therefrom that engage lid retaining members extending from opposite sides of the lid, to securely latch the lid on the tank at least when the carry handle is in a latched position. Tank latch arms are also provided that securely latch the tank to the cleaner when the carry handle is in the latched position. The tank latch arms are pivotally connected to the ends of the handle. Key pins extending from opposite sides of the tank are received in key ways in the latch arms. The key pins control the motion of the latch arms and ensure that the latch arms latch the tank to the cleaner when the handle is pivoted to the latched position.

Abstract: Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank. Nozzles for dispensing the cleaning water to a brush, a vacuum nozzle for vacuuming and returning soiled fluid to the recovery tank portion of the tank assembly is also provided. The present invention includes the method of securing a brush head assembly pivotably to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Also, the method is addressed to configuring and proportioning the bladder to insure a relatively constant load on the nozzle.

Abstract: Disclosed is a wet/dry carpet cleaner having a large tank assembly for fluids. A bladder containing fresh or cleaning water is positioned in the large tank for dispensing the cleaning water to a brush. A vacuum nozzle for vacuuming and returning soiled fluid to the recovery tank portion of the tank assembly is also provided. The present invention stems from the development of a brush head assembly which is pivotably secured to the chassis assembly and includes the driving motor, rotating brush, and spray mechanism. The pivotal securement results in the weight of the brush head assembly applying a constant force on the brush throughout the entire cleaning cycle, independent of the amount of fluid contained in the recovery tank or the bladder. Secondarily, the present invention is addressed to configurating and proportioning the bladder to insure a relatively constant load on the nozzle.
