Abstract
A personal heat control has a housing (4) accommodating a Peltier-effect unit (1), one or more batteries 15 and a timing switch (9) for selective energisation of the unit (1). The housing (4) is releasably attached to a part of a person's body, e.g. the wrist, by a strap (5) with a cooling surface cooled by the unit (1) in contact with the body part to enhance heat transfer between the person's body and the surrounding air for comfort and refreshment purposes when the unit (1) is energised.
Claims19
A personal heat control device of a person's body, comprising, a cooling surface and a heating surface thermally insulated from the cooling surface, a Peltier-effect unit for cooling the cooling surface and heating the heating surface, the Peltier-effect unit being accommodated in or on housing means connected to attachment means for attachment of the device to a part of the person's body with one of said surfaces in contact with the skin at said body part, and switch means for selective connection of the Peltier-effect unit to electrical-powering means for actuation of the Peltier-effect unit, the housing means comprising a single housing being arranged to accommodate the switch means, the Peltier-effect unit and the electrical-powering means whereby the device is a self-contained portable heat control device, and the switch means comprises a timing switch to energise the unit for a set period of time when actuated.
A personal heat control device for a person's body, comprising a cooling surface and a heating surface thermally insulated from the cooling surface, a Peiltier-effect unit for cooling the cooling surface and heating the heating surface, a Peiltier-effect unit being accommodated in or on housing means connected to attachment means for attachment of the device to a part of the person's body with one of said surfaces in contact with the skin at said body part, and switch means for selective connection of the Peiltier-effect unit to electrical-powering means for actuation of the Peiltier-effect unit, the housing means comprising a single housing being arranged to accommodate the switch means, the Peltier-effect unit and the electrical-powering means whereby the device is self-contained portable heat control device, and the switch means comprises a timing switch to energise the unit for not more than one minute when actuated.
A personal heat control device for a person's body, comprising a cooling surface and a heating surface thermally insulated from the cooling surface, a Peltier-effect unit for cooling the cooling surface and heating the heating surface, the Peltier-effect unit being accommodated in or on housing means connected to attachment for attachment of the device to a part of the person's body with one of said surfaces in contact with the skin at said body part, and switch means for selective connection of the Peltier-effect unit to electrical-powering means for actuation of the Peltier-effect unit, the housing means comprising a single housing being arranged to accommodate the switch means, the Peltier-effect unit and the electrical-powering means whereby the device is a self-contained portable heat control device, the switch means comprises a timing switch to energise the unit for a set period of time when actuated, and said switch preventing reactivation of the unit for a period of time.
A personal heat control device for a person's body, comprising a cooling surface and a heating surface thermally insulated from the cooling surface, a Peltier-effect unit for cooling the cooling surface and heating the heating surface, the Peltier-effect unit being accommodated in or on housing means connected to attachment means for attachment of the device to a part of the person's body with one of said surfaces in contact with the skin at said body part, and switch means for selective connection of the Peltier-effect unit to electrical-powering means for actuation of the Peltier-effect unit, the housing means being- arranged to accommodate the switch means and the electrical-powering means whereby the device is a self-contained portable heat control device;
- wherein the Peltier-effect unit, the switch means and the electrical-powering means are accommodated in a single housing;
- wherein the switch means comprises a timing switch to energise the unit for a set period of time when actuated;
- wherein the timings switch energises the unit for more than one minute;
- and
- wherein the timing switch prevents the reactivation of the unit for a period of time not less than the energisation time.
