Abstract

PROBLEM TO BE SOLVED: To obtain an electronic cold retaining pillow for which Peltier elements having a cushion property and silent property in combination are used. SOLUTION: The Peltier elements 3 are so mounted on the Peltier element surface in such a manner that the Peltier elements surface in contact with a fluid cooling part 4 induces heat absorption and that the Peltier element surface in contact with heat radiation fins 2 induces heat generation. Fans 1 execute force air cooling in order to suppress the temp. elevation of the heat radiation fins 2. The fluid cooling part 4 cools fluid. The cooled fluid is circulated between the pillow 6 and the fluid cooling part 4 through thermally insulating tubes 7 by a pump 5, by which the pillow 6 is cooled. The pillow 6 is constituted by placing a spacing between the inlet and outlet of the thermally insulating tube 7 to circulate the fluid over the entire part of the pillow and to resin the cold over the entire part of the pillow 6. The cushion material 10 in the pillow is a rough fibrous foam material which does not hinder the circulation of the fluid. This material relieves the increase of the internal pressure of the pillow 6 by local impact and suppresses the slop of the fluid in the inside of the pillow.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic cooling pillow using a Peltier device.

[0002]

2. Description of the Related Art Conventionally, pillows that use a Peltier element to cool and cool the head have a heat absorbing portion and a heat radiating portion in the pillow body. The heat radiation surface side of the Peltier element is in contact with a metal heat radiation fin.

[0003]

However, for the mat on which the head is in contact with the heat absorbing surface side of the Peltier element, a material having a high thermal conductivity which allows the human body to easily feel heat is preferable. Higher materials generally have less cushioning, and when the head is placed on the pillow, they feel hard and do not feel comfortable to sleep. The radiating fins in contact with the radiating surface side of the Peltier element are generally hard and have a large size in proportion to the entire pillow, which adversely affects the softness of the entire pillow. Further, in order to enhance the heat dissipation effect of the heat dissipation fins, forced air cooling is performed by the fan, but noise such as fan vibration noise and wind noise is generated near the ears. An object of the present invention is to give a cushioning property to an electronic cold-storage pillow using a Peltier element and prevent noise from being generated at the ears.

[0004]

In order to achieve the above object, the present invention provides a cooling part, which is composed of a Peltier element, a radiation fin and a fan as a noise source, apart from the pillow, and the cooling part Is cooled, the fluid is circulated between the inside of the pillow and the cooled portion, and the hard portion is removed from the pillow body.

[0005]

According to the present invention, it is possible to provide an electronic cold-storage pillow using a Peltier element with good cushioning and quietness and good sleeping comfort.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the embodiments shown in the drawings. FIG. 1 is a block diagram of the electronic cold storage pillow of the present invention.
In each of the Peltier elements 3, the direction of the current can be varied by adjusting the direction of the current so that the Peltier element surface in contact with the fluid cooling unit 4 absorbs heat and the Peltier element surface in contact with the heat radiation fin 2 generates heat. A strong current. Since the heat radiation fin 2 receives heat from the Peltier element 3 and its temperature rises,
The fan 1 performs forced air cooling in order to suppress the temperature rise of the radiation fins 2. The fluid cooling unit 4 is made of a material having good heat conduction, and the inside of the fluid cooling unit 4 is arranged so that the length of the pipe 8 through which the fluid flows is as long as possible, as shown in FIG. Cools effectively before passing through the cooling unit 4. The cooled fluid is circulated between the pillow 6 and the fluid cooling unit 4 through the heat insulating tube 7 by the pump 5 to cool the pillow 6. As shown in FIG. 3, the pillow 6 has a structure in which a space is provided between the inlet and the outlet of the heat insulating tube 7 so that the fluid circulates throughout the pillow and keeps the entire pillow 6 cool. The bag 9 is made of a material having a good thermal conductivity or a thickness, and seals the fluid while responding to the deformation against external force. The cushion material 10 is made of a coarse fibrous foam material that does not hinder the circulation of the fluid, and alleviates an increase in the internal pressure of the pillow 6 due to a local impact and suppresses the fluid inside the pillow 6 from dangling.

[0007]

As described above, as described above, the Peltier device 3
And placing the fluid cooling unit 4 and the radiation fins 2 away from the pillow 6, keeping the pillow 6 cool by using a fluid, and
Cushioning can be given to the pillow 6 by inserting the cushioning material 10 inside, and noise can be generated at the ear when the head is placed on the pillow 6 by placing the fan 1 away from the pillow 6. It is not necessary to do so, and finally the pillow 6 can be given a good sleeping comfort. Further, the shape of the pillow 6 can be changed so that a place other than the head can be used for cooling and cooling.
