Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a pillow, and more specifically to a pillow that cools the head and warms the shoulders at the same time.

(Prior art) Conventional pillows, for example, as disclosed in Japanese Utility Model Application Publication No. 58-73227, have a cooling plate closely attached to the heat absorption side of a thermoelement and a heat transfer plate of a radiator to the heat generation side. The provided thermoelectric cooling device is attached to the pillow body so that the cooling plate is on the top, the heat transfer plate is on the bottom, and a heat insulating layer is formed around the thermoelement. A mat packed with liquid-impregnated corpus cavernosum, etc. is placed thereon, and the radiation fin portion of the radiator is housed in the space formed by the pillow body, the intake/exhaust grille, and the bottom plate that closes the bottom surface of the pillow body. In the electronic cooling pillow made of
In addition, a hole passing through the heat insulating layer is provided at the upper part of the bottom plate.

(Problem to be solved by the invention) Since the conventional pillow is constructed as described above,
It is possible to cool the head with sustained cooling power, but at the same time as the head gets cold, the cold air in the vicinity cools the shoulders, making it difficult to sleep, and in severe cases, the shoulders become so cold that you can't even lift your arms. There is a problem.

This proposal attempts to solve the problem of the conventional product that the shoulders are too cold, by providing a pillow that can actively warm the shoulders at the same time as cooling the head. .

(Means for Solving the Problem) In order to solve the above problem, the present invention provides a pillow having a substantially rectangular parallelepiped shape with a cooling mat provided on the upper surface of the inclined surface so that the front part is low and the rear part is high. While forming the main body, a structure is formed in which a heat absorbing plate and a heat generating plate of different metals are brought into contact with each other by the Peltier effect of energizing, and a heat dissipating plate is connected to the side of the heat generating plate.
The structure has a heat absorbing plate at the upper part and a heat generating plate at the lower part built into the pillow body, and the pillow body has a structure in which a hole is formed in the front side continuing from the front downward slope, and the hole is formed in the pillow body. The main feature is that the heat dissipation plates of the structure are built in facing each other.

(Function) Since the present invention is constructed as described above, the front part is low;
The head can be held in a stable state on the sloped surface with the rear end raised high, and the head is cooled by a cooling mat that is in contact with a heat-absorbing plate that absorbs heat using the Peltier effect. In addition, a heat sink was connected to the side of the heat generating plate, and the heat sink faced the hole in the front side that formed the front rising wall of the pillow body, so the warm air from the heat sink through the hole , the shoulder facing the hole can be actively heated. In other words, cool your head,
It can keep your shoulders warm.

(Example) Next, an example of the present invention will be described based on the drawings.

Reference numeral 1 denotes a pillow body, and the body 1 has dimensions of 6 to 8 cm in height, 25 to 30 cm in the front-back direction, and 50 to 60 cm in the left-right direction, and has an inclined surface 2 whose upper surface is gently sloped downward to the front.
It is made into a substantially rectangular parallelepiped with .

In addition, in other words, the front side wall 3 is provided with a large number of holes 4 in order to facilitate heat dissipation of warm air from the heat sink 11, as will become clear from later description, and the material of the pillow body 1 does not matter. However, they are formed by molding various synthetic resin sheets or synthetic resins. Reference numeral 5 denotes a cooling mat that is detachably attached to the inclined surface 2, and the cooling mat 5 is attached to the inclined surface 2 as shown in the figure in order to stabilize its position.
It is preferable that the mat 5 is removably fitted into a recess 6 formed in the mat 5, and the mat 5 is formed by, for example, enclosing a soft synthetic resin foam impregnated with water in a flat plate-shaped bag made of synthetic resin. be.

Incidentally, if a cooling plate 5a made of metal such as aluminum is attached to the lower surface of the cooling mat 5 as shown in the figure, the cooling efficiency can be improved.

Further, 7 is two dissimilar metals 8 and 9 whose longitudinal section is approximately U-shaped in order to generate a Peltier effect when energized.
A structure in which a dissimilar metal 8 is used as a heat absorbing plate, a dissimilar metal 9 is used as a heat generating plate, and a heat dissipating plate 11 is integrally formed on the side of the heat generating plate. The body 7 has a heat dissipating plate 11 built into the pillow body 1 facing the hole 4.

Also, known metals are used as the dissimilar metals 8 and 9.

Furthermore, it is preferable to provide a large number of fins on the heat dissipation plate 11 to widen the heat dissipation area.

Furthermore, it is possible to provide a notch 12 in one of the dissimilar metals 8 and 9, for example, in the dissimilar metal 8, as shown in the figure, and reduce the cross-sectional area thereof to control heat conduction between the dissimilar metals 8 and 9. It is preferable.

Further, the current from the power source X is passed through the voltage/DC converter Y to the dissimilar metals 8 and 9.

Further, numeral 13 in the drawing represents a filler filled in the pillow body 1, and the filler 13 is made of a soft and elastic material such as sponge rubber.

(Effect of the invention) Since the present invention is configured as described above, heat is absorbed by the dissimilar metal 8, that is, the heat absorption plate side, due to the Peltier effect.

Therefore, the head is cooled through the cooling plate 5a and the cooling mat 5, and since cold air is accumulated in the mat 5, the cold retention effect is improved.

On the other hand, the dissimilar metal 9, that is, the heat generating plate generates heat, and the heat warms the shoulder facing the holes 4 via the heat sink 11 and the large number of holes 4. Further, as described above, since the dissimilar metal 8 is provided with the notch 12 to reduce its cross-sectional area, the heat generated on the dissimilar metal 7 side is difficult to conduct to the dissimilar metal 8 side, and the heat absorption on the dissimilar metal 8 side is reduced. This makes it difficult to inhibit the action.

In other words, the pillow according to the present invention uses the Peltier effect to cool the head and warm the shoulders, allowing for a good night's sleep, with the remarkable effect that there is no need to worry about stiff shoulders like with conventional products.
