Description

Pillow having air cooling function {Pillow having air cooling and heating function}

The present invention relates to a pillow having a cooling and heating function that can be temperature controlled, more specifically, by adjusting the temperature of the fluid medium pack filled inside through the heat absorbing and heat-generating action of the thermoelectric element when the power is applied, the user's proper sleep temperature In the present invention, the present invention relates to a pillow having a heating and cooling function that can comfortably sleep.

Pillows, which are usually used to protect the head and neck during sleep, are filled with fibers or dried grains to sleep comfortably. Since such pillows are repeatedly used for a long time during sleep, the restoring force is lowered and the discomfort is felt. Since the head and the neck are in contact for a long time, heat is generated so that they do not feel comfortable and fall back during sleep.

In ancient times, the oriental medicine fever (두) called "head cold and feet must be warm," and in fact, the source of various brain diseases have been reported academically has been caused by the head warm. Thus, our ancestors used mung bean, glitches and chrysanthemum pillows, which are good for insomnia and hypertension, or blue millet instead of cotton to make the baby's head smart and heat the head. However, such natural materials were difficult to obtain and the price was too high to be used in real life.

Therefore, the present invention was devised in view of the above circumstances, and the temperature control of the fluid carrier pack is possible through the endothermic and exothermic effects of the thermoelectric elements installed therein, so that the user can take a good night's sleep by cooling the pillow body to a desired temperature. The purpose of the present invention is to provide a pillow having a heating and cooling function that can be conveniently used for cold and hot spots.
