Abstract

PURPOSE: To impart warm and cool feelings to a person using bedding by providing a heat source or a radiation fin to the end part on the edge part side of bedding among the end parts of the heat pipes arranged to bedding. CONSTITUTION: In the winter, one ends of heat pipes 2 are held between a heat source 6 and a reflecting plate 5 by thumbscrews 7. When a current is supplied to the heat source 6, the heat generated from the heat source 6 is transmitted to the other end 2b of the heat pipe 2 to be radiated to apply a warm feeling to a person. In a season not requiring warm air, the heat source 6 and the reflecting plate 5 are loosened by thumbscrews 7 to be detached. In the summer, one ends of heat pipes 2 are held between radiation fins 8, 9 by thumbscrews 10. The heat by the bodily temp. of a person is transmitted to one ends 2a of the heat pipes 2 from the other ends 2b thereof and radiated by the radiation fins 8, 9 to impart a cool feeling to a person. In a season not requiring the cool, the radiation fins 8, 9 are detached by loosening thumbscrews 8, 9.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to cooling and heating bedding using heat pipes.

[Conventional technology]

FIG. 5 is a plan sectional view showing a conventional heating bedding disclosed in, for example, Japanese Utility Model Publication No. 6O-19241i.

In the figure, (l) is a blanket, (2) is a heat pipe arranged in parallel inside the blanket +17, and (2a) is a blanket (1
), one end (2b) is the other end located in the center, and (3) is a heat source provided at one end (2a) of the heat pipe (2) and connected to the power source. .

Here, both ends of the heat pipe (2) are closed and placed on the inner surface of the round steel pipe.

A quick (medium moving layer) made of porous material is formed to create a vacuum inside, and a small amount of working fluid such as water or fluorocarbon is sealed in it. That is, when the temperature at one end (2a) of the steel pipe rises to a certain temperature, the zero working fluid is heated and becomes steam,
The heat is transferred to the other end (2b), which is a low temperature part, and is radiated. The heat is dissipated, the steam is condensed and liquefied, and it becomes a working fluid again due to capillary action caused by the wick at one end of the steel pipe (2
It has the effect of being refluxed to a).

Conventional heating bedding is configured as described above, and when the heat source (3) is connected to a power source, the heat source (3) generates heat and heats one end (2a) of the heat pipe (2). 2), as mentioned above, transfers this heat to the other end (2b) of the heat pipe (2) and radiates the heat at the other end (2b), so 9
Blanket (1) Fi warms the blanket (!) to give the user a comfortable night's sleep. In this way, it is possible to obtain heated bedding that is safe and uses less electricity.

[Problem that the invention seeks to solve]

In conventional heated bedding as mentioned above, heat pipes (2)
Since it is heated by the heat source (3), it is possible to give a warm feeling in the winter, but it is not possible to give a cool feeling in the summer;

There is a problem in that it is necessary to use a cooling device, electric fan, etc.

This invention solves the above-mentioned problems, and aims to provide cool and warm bedding that can provide a feeling of warmth and coolness simply by replacing the device at the end of the heat pipe placed in the bedding. .

[Means for solving problems]

In the cool and warm bedding according to the present invention, the ends of the heat pipes arranged in the bedding are arranged at the ends of the inner bedding on the edge side.

It is equipped with a heat source or heat dissipation fins that can be attached or removed.

[Effect]

In this invention, a heat source or heat dissipation fin is attached to one end of the heat pipe, so that when a heat source is attached, heat moves from one end to the other end, and when a heat dissipation fin is attached, heat moves from the other end to one end. heat is radiated.

〔Example〕

Figures 1 to 4 are diagrams showing one embodiment of the present invention.
The figure and FIG. 2 are enlarged views of one part of FIG. 5.

FIG. 3 is a perspective view of the main part of FIG. 1, and FIG. 4 is a perspective view of the main part of FIG. 2. Portions similar to those of the conventional device are designated by the same reference numerals.

In the figure, (5) is a reflection plate placed below one end (2a) of the heat pipe (2), and (6) is a sheet heating element made of a conductive polymer material. One end of (
The heat source (8) is located above the heat pipe (2a) and is fastened to the reflector (5) with a thumbscrew (7).
The heat dissipation fin (9) is made up of a plurality of metal pieces arranged perpendicularly to the heat pipe (2) on the lower side of 2a).

In the cool/warm bedding configured as described above.

In winter, heat pipes (

). When the heat source (6) is energized, the heat generated by the heat source (6) is transmitted to the other end (2b) by the heat pipe (2), where it is radiated, as in the conventional device. gives a feeling of warmth. When the season when warm air is not needed, connect the heat source (6) and reflector (5) with the thumbscrews (7).
Loosen and remove.

Next, in the summer, as shown in Figures 2 and 4.

At one end of the heat pipe (2) there is a heat dissipation fin +81. (9)
is clamped with thumbscrew αQ. Now the heat from the body temperatures of the nine people is transferred from the other end (2b) of the heat pipe (2) to one end (2a).
transmitted to.

Heat dissipation fins (81, (91) dissipate heat and give a person a cool feeling.In the season when cool air is not needed, heat dissipation fins +81.
(Remove 91 by loosening thumbscrew αΩ.

〔Effect of the invention〕

As explained above, in this invention, a heat source or a heat dissipation fin is detachably attached to the end of the heat pipe arranged on the bedding, on the edge side of the bedding, so that it can be adjusted according to the season. By simply replacing the equipment at the end of the heat pipe, the bedclothes can provide a warm and cool feeling to the person using the bedclothes, and are extremely safe to use.
