    Abstract: A blower urges an airflow, at a rate according to a user-controlled flow rate command, through an electric heater and the electrical heater heats the airflow at a heater power based on a user-input temperature command, the user-input flow rate command, and a measured mass flow rate of the airflow. The heater power is calculated based on the heat energy required to heat air to the given reference temperature, at a flow rate corresponding to the measured mass flow rate. Optionally, the temperature of the air entering the electric heater is measured, and the heater power is calculated based on the heat energy required to heat air from the measured temperature to the given reference temperature, at a flow rate corresponding to the measured mass flow rate.

    Abstract: An airflow system enhances airflow in a hand-drying apparatus which expels a stream of sterilised, hot air for drying of hands. Inside the apparatus, the airflow is decelerated by one or more filters. Therefore, the system is provided with an airflow-pathway that is progressively smaller along its pathway in respect of flowthrough cross-section. The airflow is enhanced by flowing initially through a larger part of the airflow-pathway, and subsequently through a smaller part of the airflow-pathway after which the airflow exits the apparatus. To enhance the airflow, a universal commutator motor is used to drive an appliance that provides air movement. The motor comprises magnetic field generating means, a rotating armature adapted for rotational motion in operative association with the magnetic field. A ratio of magnetic field strength at the armature to the magnetic field strength within the magnetic field is less than about 1 to 1.

    Abstract: An electric heater and a fan are enclosed within a cylindrical case for blowing warmed air from one end of the case. The case is supported at a distal end by a flexible strut enabling selective positioning of the case for directing the warmed air in a preferred direction. The flexible strut is rotationally engaged in a base. The base supports the flexible strut and the case in a selectable orientation. A lamp is fixed to the underside of the case in a position for directing illumination downwardly; the lamp positioned such that a forward end of the case provides shadowing of the light from a baby's eyes.

  • Patent number: 7278225
    Abstract: A foot-drying device includes a body including first and second vertical sides, and an open front face sloping upward away from a front edge thereof. The body is hollow, forming a chamber that extends from a bottom surface to a top surface thereof, and has a rear panel hingedly coupled thereto. A foot pad is seated over the open front face and is provided with apertures for draining water therethrough. A mechanism is included for diverting the water outwardly from the chamber as the water drips down through the apertures of the foot pad. A mechanism is included for introducing heated air into the chamber such that the heated air is quickly engaged with the user foot. The heated air is evenly discharged from the apertures such that the water on the user foot is completely expelled away therefrom. The air heating mechanism is disposed above the water diverting mechanism.

  • Patent number: 7184655
    Abstract: A footrest is provided comprising a base portion for placement on a supporting surface, a footplate connected to the base portion for receiving a foot of a user of the footrest, a heater connected to the base portion, an air intake system connected to the heater for drawing a first mass of air into the footrest, and an exhaust connected to the heater for expelling a second mass of air from the footrest. The heater receives the first mass of air, heats it, and expels it as a second mass of air. A warm air shield helps redirect the second mass of air expelled through the exhaust at the foot of the user placed on the footplate. The footplate may be made to pivot with respect to the base portion, or may be provided with a control knob so that a user may control the heater using her foot.

  • Patent number: 7039301
    Abstract: After washing, the hands are dried rapidly and comfortably by using a shaped high speed flow of heated air. The air flows in a direction controlled by an air outlet shaped to retain much of the exiting forceful air flow and temperature at a distance where the hands are dried. The air entrainment is controlled so that the properties of the air flow are not diluted by the air entrainment to a point where the drying performance is degraded. The forceful air flow blows off most of the loose water on the hands. The forceful air flow also reduces the stagnation boundary layers in the hands so that the evaporation removal of the remaining film of water is improved. These result in reduced drying time and comfort during and after drying.

  • Patent number: 6959145
    Abstract: An apparatus melts snow off a person's footwear without the need for the wearer to take off the footwear. In particular, the apparatus is for melting ice and snow off the footwear, for example shoes, boots or sneakers, of the wearer by a directed and accurately disseminated heat flow. The heat flow is directed in a manner which facilitates the removal, deposition and collection of melting snow and ice from shoes of a wearer at a desired location, e.g., in a threshold or landing, adjacent an entry/exit door of a residence or commercial building before such snow and ice and any contaminant therein can be tracked into the building.

  • Patent number: 6922909
    Abstract: By providing a plurality of portals in a housing which forms a hair dryer attachment which is merely fixed to the exist portal of any conventional hair dryer, a hair dryer attachment is realized which is capable of substantially reducing the drying time required for drying the hair of any individual, while also being easily employed and comfortable. In the preferred embodiment, at least one raised, sloping panel is formed adjacent the inlet portal of the attachment with the panel sloping outwardly from the generally circular shaped inlet portal. In addition, a plurality of apertures or portals are formed in the panel for enabling ambient air to freely flow therethrough. In this way, the heated air flowing through the central portion of the attachment creates a low-pressure zone on the inside surface of the portals, drawing ambient air through the portals into the interior of the hair dryer attachment, thereby enabling the quantity of the air reaching the hair of the user is substantially increased.

  • Patent number: 6910281
    Abstract: A hair drier having the capability of efficiently supplying hot air and minus ions from different outlets is provided. This hair drier has a hollow housing with an air suction inlet and an air outlet. In the housing, a fan and a heater are disposed in an air-flow channel formed between the air suction inlet and the air outlet. The air sucked in the housing by the fan is heated by the heater, and then ejected from the air outlet. The housing also has an ion-flow channel formed as an independent flow channel from the air-flow channel, and an ion outlet provided at a different position from the air outlet to eject minus ions generated by the minus ion generator. The minus ion generator is disposed in the ion-flow channel.
