Description

[0001] The present invention relates to a portable band having a warming and cooling function,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a portable band that is worn or attached to a body-specific region. More particularly, the present invention relates to a portable band having a warming and cooling function for warming or cooling a body- Portable bands.

An improved scarf buff is commonly used to protect and protect the neck and face during outdoor activities. Buffs can be used to warm the neck around the winter, and it is a household item that protects the skin from exposure to ultraviolet rays by covering the neck or face during outdoor activities in summer.

Buffs, also called muffs or muffs, have a cylindrical shape with both open ends. Since the buff is used in a manner that the cylindrical cloth is turned over to the neck or face, it is easier to wear than a general scarf or shawl, and is worn in a form adhered to the face or neck, so that the activity is free.

However, a conventional general buff is limited to simple functions such as keeping warm or shutting off sunlight, that is, a general function as a scarf. Therefore, in order to maintain the body temperature during hot summer or cold winter, a separate auxiliary tool such as a portable fan or a hot pack is used in addition to the buff.

On the other hand, a thermoelement uses a Peltier effect due to the interaction of heat and electricity, and its use is unlimited. Therefore, it is widely used for various purposes such as automobiles, ships, general machinery, household appliances, household goods, and the like.

Therefore, it is necessary to carry a separate auxiliary tool in addition to the buff to maintain the body temperature during the hot summer or during the cold winter, by taking into consideration the effect expected from the thermoelectric element, that is, the heat and the endothermic effect due to the interaction of heat and electricity, The present invention has been made to solve the hassle.

That is, in another embodiment of the present invention, heat is directly supplied to the skin of the user in contact with the heat transfer plate 12, or the heat is taken away by heating to cool the heat transfer plate 12, And the cooling air or the warm air generated by air convection in the housing part 14 is discharged to the outside through the cooling / heating flow path 143 and the discharge opening 144. In this way,

On the other side, it is possible to reduce the size of the heat transfer plate, which is a metal material in contact with the user's skin, which is advantageous for weight reduction and portability of the device.
