A range hood cleaning assembly utilizes compressed air to drive accumulated grease on range hood surfaces towards drainage holes. A plurality of air dispensers, preferably air hoses and directional nozzles, through which compressed air from at least one source of compressed air is blown, direct compressed air against surfaces within a motor housing interior, on the fan(s) and within grease trays to drive accumulated grease towards drainage holes. The air dispensers may be attached to a plate mounted within the motor housing interior about a motor and above a fan, may be integral or releasably attachable to the motor housing or may be integral or releasably attachable to grease trays. The compressor may be set to activate automatically or may be activated manually.
A cleaning assembly for use in a range hood comprising a motor housing having an interior defined by upper, lower and side surfaces containing at least one motor and at least one fan and having at least one drain hole, said cleaning assembly comprising:
A cleaning assembly for use in a range hood comprising a motor housing having an interior defined by upper, lower and side surfaces containing at least one motor and at least one fan, and a grease tray releasably attachable to said motor housing, said grease tray comprising an opening, first, second and third tray walls extending around said opening, a first trough formed between said first and second tray walls, a second trough formed between said second and third tray walls, and at least one drainage hole, said cleaning assembly comprising:
A range hood cleaning assembly, said range hood having a motor housing having upper, lower and side surfaces that generally defines an enclosure containing at least one motor and at least one fan, said lower surface having at least one intake opening and at least one drain hole, said intake opening being defined by a wall depending from said lower surface and projecting into the interior of said enclosure, and a tray releasably connectable to said intake opening, said tray comprising an opening, first and second tray walls extending around said opening, and a floor between said first and second tray walls, said cleaning assembly comprising:
A cleaning assembly for use in a range hood comprising a motor housing having an interior defined by upper, lower and side surfaces containing at least one motor and at least one fan and having at least one drain hole, said cleaning assembly comprising:

Term end not estimated
This invention relates to range hoods, and more particularly to a cleaning assembly for a range hood wherein compressed air directs accumulated grease accumulated within the range hood to an external grease receptacle.
Range hoods are used above cooking surfaces to remove grease, common odors and hazardous gases created during the cooking process. Typically, range hoods have a pair of motors horizontally installed in a motor housing within the hood body. Each motor drives a fan. The fans suck air from the cooking area below and force it through the motor housing to ventilation piping.
As the vaporized grease contained in the entrained air travels through the motor housing, some of it condenses on the inside walls of the housing from where the shaping of the walls and floor of the housing directs the grease to a circular grease catcher mounted below each fan opening. Grease catchers are known in the art as illustrated in U.S. Pat. Nos. 6,216,686 B1 and 5,537,988.
The invention will be described by reference to the detailed description of the preferred embodiment and to the drawings thereof in which:
FIG. 1 is a sectional view of a range hood according to the preferred embodiment of the invention with the right hand portion of the figure providing a deeper sectional view than the left hand portion of the figure;
FIG. 2 is a view taken along line 2-2 of FIG. 1;
The present invention relates to a cleaning assembly for a range hood.
The cleaning assembly is composed of a source of compressed air such as a compressor and air dispensers for directing the compressed air against grease coated surfaces within the range hood. The compressed air is used to drive accumulated grease out of the range hood. This will be described in greater detail below by reference to the preferred and alternative embodiments.
The preferred embodiment of a range hood 100 with a cleaning assembly according to the invention is illustrated in FIG. 1. In the preferred embodiment, the motor housing 110 includes an integral grease catcher. The housing 110 defines an enclosure and is mountable within a further enclosure formed by the hood body generally indicated by the numeral 102. The interior of the housing 110 is coated with a non-stick material so as to facilitate grease removal and is separated into two substantially similar, separate chambers 2, 4 as best illustrated in FIG. 2. The chambers 2, 4 have intake openings 112 shown in FIG. 3, and ventilation holes (not shown). The ventilation holes project through the upper surface of hood body 102 when the housing 110 is attached to the interior of the hood body 102.
