A hair dryer comprises a fan (F) for generating an air flow, and a drying chamber (HC) having a hair inlet (II) into which hair can be guided by the air flow. A cross-section of the drying chamber (HC) has a first dimension in a first direction, which first dimension is at least 5 times larger than a second dimension in a second direction perpendicular to the first direction, wherein the first and second directions are perpendicular to a direction of the air flow. The drying chamber (HC) may be folded in that the drying chamber has a U-turn in the direction of the air flow. A first area of the cross-section of the drying chamber (HC) at the U-turn may be smaller than a second area of the cross-section in the middle between the hair inlet (II) and the U-turn. A hair inlet (II) of the drying chamber (HC) may be shaped to follow a contour of a user's head. The hair dryer may be arranged for heating hair from multiple sides. A wall of the drying chamber (HC) may be provided with a hydrophilic or water absorbing or water surface tension reducing material. The water absorbing material may be regenerated by means of hot air. The drying chamber (HC) may be openable, whereby the drying chamber can be cleaned. The hair dryer may have a sensor (MS) for sensing temperature and/or humidity of the air flow at an air outlet of the hair dryer, and a part of the air flow may be recirculated based on an output of the sensor (MS). The hair dryer may have a nozzle to channel hot air towards a user's scalp. A wall of the drying chamber (HC) may be shaped so as to style the hair and/or increase a contact area that is in contact with the hair.

The present invention relates to a hair dryer or hair drying system and process. The body hair dryer is a improve idea, and method for drying body hair in or on humans and certain animals. The preferred hair dryer will be a hair drying unit consisting of an electrical motor and blower with a heating element and thermostat to regulate temperature from hot to warm with attached plastic, nylon, wood or any other non-electrically conductive tubing that extends downward to the floor that has piping or tubing that creates a stationary base that can be stood upon as with the feet of human or located at or near the feet of humans, and the hoofs or paws of some animals which will blow a temperate range of air from hot to warm, and from warm to cool in an upwards direction of the body, while standing vertically, to aid in the hair drying process. The body hair dryer once manufactured will reduce the amount of time normally taken to dry large areas, and amounts of hair, wool or fur, after an individual or animal has become wet by bathing, showering, sweating, swimming or being emersed into water by any means. Until now, after being exposed to, or emersed into water or moisture and being removed from said water or moisture the typical process included the use of a large cloth towel, and in some cases hand-held heated hair dryers to dispel or aid in the dissipation process of most of the water or moisture that is present on the body. These methods typically leave the outer or external body hair in certain areas not completely dry and in some case with excess moisture.

A heater assembly for a haircare appliance includes an air duct defining an air flow path extending from an upstream end to a downstream end; a first heater element positioned in the flow path, the first heater element having a first electrical path defined between cut-outs in a first sheet, the air flow path extending through said cut-outs; and a second heater element positioned in the flow path downstream of the first heater element, the second heater element having a second electrical path defined between cut-outs in a second sheet, the air flow path extending through said cut-outs. The heater assembly includes electrical circuitry for connection to a power source. The first and second electrical paths are provided in respective first and second circuit branches which are connected in electrical parallel within said circuitry.
