    Abstract: A hand-held grooming device has a comb which protrudes from a slot through which air is drawn and used by a fan driven by an electric motor. Loose hairs and dandruff are thus drawn into the device and collected by a filter. The same air is then blown out through an orifice which can be rotated about the axis of the device, at a point adjacent the point from which the air was drawn into the device. A heater can be switched on to heat the exhaust air. Thus, the same air which is drawn into the device to remove loose hairs and dandruff, after such removal is returned to the same location to dry or warm or cool the location from which the hair was withdrawn. The device is useful not only in connection with hair but also the removal of lint or dust from clothing.

    Abstract: An apparatus in which the heat for blow drying a dog's hair is generated from the cooling of a motor and from fluid friction due to air being forced through passageways within the apparatus. The apparatus includes an enclosure and at least one blower motor combination such as the type used in vacuum cleaners. The blower forces air through the motor where the air is heated and then discharged into a pressurized section of the enclosure. Part of this air is then recirculated back to the blower inlet and the rest is discharged through an air hose that is used to dry the animal. A bypass valve is provided to adjust the fraction of the air that is recirculated. Controls are also provided to regulate the amount of fresh air that enters the enclosure and to vary the rotational speed of the blower motor. With proper adjustment of these controls, a very efficient pet hair drier cycle can be achieved.

A regeneratable drying agent such as aluminum oxide, silica gel, or the like constitutes the moisutre absorbing filter insert. In a preferred embodiment a fan driven by an electric motor sucks the drying air through a slit in a double-walled hood which fits over the hair so that the air sucked through the slit must pass through the filter insert into an inside wall portion of the hood which is perforated and lies next to the hair which is being dried. A holder for the hood is swivelably mounted so that it can be fixed to a wall. Moist air which reaches the outside hood is recirculated to the inside wall and again fed to the filter insert for repeated dehumidification. In this manner at least part, if not all, of the air is dehumidified.
