Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a pillow, and particularly to a pillow that cools the head of the human body and allows a comfortable sleep.

(Background Art) Pillows with built-in cooling means have been provided, for example, a one-child cold pillow is described in Japanese Utility Model Publication No. 43-30271. -1 It is designed to help people sleep better by cooling the head of the human body.In this case, when the head of the human body is cooled, the neck and shoulders of the human body are also gradually cooled. Blood circulation in the neck and shoulders of the human body deteriorates,
There was a problem in that it could not be used for a long time because it caused stiff shoulders and nervous disorders.

[Purpose of the invention]

The present invention has been made in view of the above points, and its purpose is to provide a pillow that cools the head of the human body and warms the neck and shoulders of the human body.

[Disclosure of the invention]

A first embodiment of the present invention will be described below with reference to FIGS. 1 to 4. 1 is a rectangular casing made of cloth, rubber, etc., which protrudes from the longitudinal side and the casing 1.
Rectangular protrusion 2 made of cloth, rubber, etc. with a lower height than
is adjacent.

A cooling means 8 composed of a thermoelectric element 3 and cooling fins 6 fixed to the heat absorbing part 4 of the thermoelectric element 3 is disposed inside the casing 1, and the cooling means 8 is arranged between the upper surface of the cooling fin 6 and the upper wall of the casing 1. A cold storage member ■0 is disposed between the inner surface and the inner surface. The thermoelectric element 3 is made by joining two pieces of metal or a metal and a semiconductor, and when a current is passed through the thermoelectric element 3, heat is generated or absorbed at the joint, resulting in the so-called Bertier effect.

A heating means 9 composed of the thermoelectric element 3 and a radiation fin 7 fixed to the heat generating part 5 of the thermoelectric element 3 is disposed inside the protrusion 2, and the upper surface of the radiation fin 7 and the protrusion 2 A heat storage member 11 is disposed between the inside of the earthen wall and the inside of the earthen wall.

The cooling fins 6 and the heat dissipating fins are each made of a metal with good thermal conductivity such as aluminum or copper, and the cool storage member 10 and the heat storage member 11 store water in an outer case made of vinyl 1 or the like. It is made up of things. A heat insulating cuticle is disposed between the lower surfaces of the cooling fins 6 and the radiation fins 7 and between the thermoelectric element 3 and the heat storage member 11, and the cooling means 8 and the heating means 9 are arranged in one thermal unit to form the casing 1. and protrusion 2
This prevents heat exchange between the casing 1 and the protrusion 2, and also prevents heat from dissipating and absorbing within the casing 1 and the protrusion 2. The cooling means 8, the heating means 9, the heat insulating cuticle, the cold storage member IO, and the heat storage member H except for their upper surfaces are surrounded by a cushion member opening made of expandable polyurethane foam, cotton, or the like. A power cord 14 is connected to the thermoelectric element 3 via a transformer 15 and a switch 16, and when current is passed through the thermoelectric element 3, heat is generated in the cooling part 4 of the thermoelectric element 3 due to the Beltier effect. is absorbed and heat is generated in the heat generating part 5, so that the water stored inside the cool storage member 10 is cooled by absorbing the heat through the cooling fins 6 fixed to the cooling part 4. The heat storage member 11 is applied to the heat generating portion 5 by 6□1, e.g. . Eh, wa Also, heat is given to the water and it is warmed up. The water stored in the cold storage member 10 and the heat storage member U has low thermal conductivity and releases heat, so the cold storage member 10 retains coldness and the heat storage member U retains warmth.

As shown in FIG. 4, the pillow of this embodiment is used when a person lies on his or her back, with the head of the human body placed on the casing 1 and the neck and shoulders placed on the protrusion 2. As a result, the head of the human body is cooled by the cold storage member 10 via the upper wall of the casing 1, and the neck and shoulders of the human body are warmed by the heat storage member 11 via the upper wall of the protrusion. The cold storage member 0 and the heat storage member 11 are made of vinyl or the like and store water in their outer shells, so they have elasticity, and the head, neck, and shoulders of the human body are positioned on the pillow of this embodiment. It has a soft touch and feels good when used. In addition, in general, in pillows that use thermoelectric elements to cool the human head, it is necessary to dissipate the heat generated in the heat generating part of the thermoelectric element to the outside of the pillow, which makes the structure complicated and Thermal efficiency was poor. In the pillow of this embodiment, the heat generated in the heat generating part 5 of the thermoelectric element 3 is transferred to the heat dissipating fins 7.
Since the heat is supplied to the heat storage member 11 through the heat storage member 11, the thermoelectric element 3 of the cooling means 8 can serve as the heating means 9, and there is no need to release heat to the outside of the pillow, resulting in a simple structure and good thermal efficiency.

Next, an example @2 of the present invention will be described based on Figure @5. The heating means 9 is composed of a planar heater 17, and the planar heater ν is disposed inside the protrusion 2, and the cooling means 8 is connected to the thermoelectric element 3 and the heat absorption part 4 of the thermoelectric element 3. It is composed of fixed cooling fins having an L-shaped cross section, and a cool storage member 10 is disposed between the upper surface of the cooling fins and the inner surface of the upper wall of the casing 1. A radiation fin 19 is fixed to the heat generating portion 5 of the thermoelectric element 3, and the radiation fin 1
9 is exposed on the side wall of the casing 1, and radiates the heat generated in the heat generating portion 5 to the outside. A heat insulating material is disposed on the lower surface of the planar heater 17 and cooling fins, and the heat insulating material 12% planar heater 17, the portion excluding the upper surface of the cool storage member 1O, the thermoelectric element 3, and the heat dissipating fin 19
is surrounded by the cushion member B. In the pillow of this embodiment having the above configuration.

Since the cooling means 8 and the heating means 9 are configured independently, it is possible to operate only one of them, cooling the head of the human body but not warming the neck and shoulders of the human body, or vice versa. Depending on the user's needs, the powder can be used to warm the shoulders but not to cool the head of the human body. Of course, it goes without saying that it can cool the head of the human body and also warm the neck and non-next parts. Moreover, instead of the planar heater 17, the heating means 9 may be configured with a heater such as an infrared heater. The other configurations are similar to the vJx embodiment described above.

In the embodiment @1 and the second embodiment, the protruding part 2 is provided integrally with the casing 1, but the casing 1 and the protruding part 2 are formed independently, and the casing 1 and the protruding part 2 are formed separately.
It is also possible to freely connect and separate them using connectors, etc.

〔Effect of the invention〕

As described above, the present invention incorporates a heating means in a casing that incorporates a cooling means, and also has a protrusion lower than the casing adjacent to the casing, thereby cooling the head of the human body and cooling the neck and shoulders of the human body. By heating and cooling the head of the human body, the neck and shoulders of the human body are also cooled at the same time, thereby preventing stiff shoulders, neuralgia, etc., allowing use for long periods of time, and providing a comfortable sleep.
