Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a heat sales container capable of directly selling thermal energy, and is particularly suitable for using the sold heat directly for heating. The present invention relates to the container, a method of handling the container, and a method of using the container.

[Conventional technology]

Conventionally, it has not been possible to sell thermal energy in the same energy form as electrical energy.

The present invention stores thermal energy, that is, heat itself, in a container so that it can be used directly and supplies it to a consumer, and then recovers the container after the heat is used so that the container itself can be used repeatedly. It has been made available for use.

[Problem to be solved by the invention]

When selling energy such as heat or electricity, it is necessary to set a unit price for the energy itself to be sold, and for electricity, the unit price is set per KWH (kilowatt hour).

Similarly, in the case of thermal energy, it is necessary to determine the unit price based on the amount of heat (cal), and for this purpose, the amount of heat at the time of sale must always be guaranteed by some means.

In other words, when heat is sold in a container, the amount of heat contained in that container must not be undefined or insufficient, and at least the minimum available amount of heat equivalent to the selling price must be equal to the physical amount. It must be quantitatively guaranteed by measurements using measuring means or by calculations with physically verifiable grounds.

Also, to target thermal energy directly for sale.

As mentioned above, in conjunction with the development of a container that allows the amount of heat contained in it to be known, it is necessary to develop appropriate methods for handling and using the container, and by solving these problems,
It becomes possible to directly sell thermal energy itself.

[Means to solve the problem]

According to the present invention, a heat storage body in which a latent heat storage material that changes phase and stores heat by supplying thermal energy from the outside is housed in a sealed chamber has heat dissipation characteristics at the time of heat release of the heat storage body. A heat-sales container that can be surrounded by a heat insulating material that can control heat as required and can be inserted into an exterior body adapted to a desired heating section, and a plurality of each of the heat storage bodies and exterior bodies, and a plurality of heat storage bodies and exterior bodies are prepared. There is also a container for heat sales in which one of the heat storage bodies surrounded by a heat insulating material is placed in one selected exterior body, and a container for heat sale in which the heat storage body is placed in the exterior body. After the stored heat is used, separate the heat storage and outer packaging in this container before using it again.

In addition to storing heat in the heat storage body, this heat storage body is
A heating tool for warming the body by wrapping it with a heat insulating material and inserting it into the outer package to form a container for heat sales again, and then gradually extracting heat from the container itself for heat sales. In addition, the method of handling the container, which is characterized by the use of heat sales, which is used as a feature of what is used, is the process of storing one of the numerous heat storage and heat storage in the process. , a step of wrapping the container with a required heat insulating material and placing it in one of a number of exterior bodies to form a container for heat sales, and a step of using the heat stored in the container;
A method for using the container is provided, comprising the steps of recovering the container after the heat has been used, and separating the heat storage body and the exterior body of the recovered container and sorting them into a number of heat storage bodies and a number of exterior bodies. Thus, the above problem is solved.

[For production]

Since the heat storage body is a latent heat storage material, the amount of heat generated per weight during phase change is precisely constant depending on the substance used for the material, and as a result, the heat storage material stores heat and becomes completely liquid. The minimum value of the amount of heat that can be taken out from a state where the heat is kept at a temperature below the phase change point is exactly 0, which is guaranteed according to the weight of the heat storage material, and the heat storage material and the exterior body should be handled separately. Therefore, various heating methods can be applied to heating the heat storage body. The exterior body can be selected and adopted with an exterior shape depending on the purpose of use.

According to the method of using the heat sales container according to the present invention, a large number of heat storage bodies and a large number of exterior bodies can be combined as appropriate, so that damaged or dirty items can be removed from the heat storage bodies and exterior bodies, and You can exchange things for sip.

The heat storage body and the exterior body can be used individually and repeatedly.

〔Example〕

FIG. 1 shows the heat usage state of the heat sales container according to the present invention.
This is an example of a heating cushion for heating.

(1) is a heat storage body, (2) is a heat insulating cushion material, (3)
is the zafuton cover.

The heat storage body (1) is made of two stacked plastic sheets (4)
A bag body (5) whose peripheral part (4a) is liquid-tightly bonded, a heat storage material (6) housed in a sealed chamber (5a) in the bag body (5), 6) is charged into the
It is constructed with a core material (7) made of nonwoven fabric or the like that suppresses fluidity when the heat storage material (6) accumulates heat and liquefies, and maintains the shape of the bag body (5) appropriately.

The heat storage material (6) is generally referred to as a phase change heat storage material or a latent heat storage material, and absorbs thermal energy and stores heat when changing from a solid phase to a liquid phase, and conversely, when changing from a liquid phase to a solid phase. When changing, it has the property of emitting heat energy and generating heat, and suitable materials for this purpose include polyethylene glycol-based materials and sodium acetate-based materials.

Typically, polyethylene glycol-based heat storage materials have a phase change point, i.e., a melting point of 55°C, of 45 to 46 c/g.
The sodium acetate-based heat storage material has a melting point of 55°C and absorbs and generates heat of 60 cal per gram.

Therefore, based on the weight of the heat storage material (6) used in the heat storage body (1), the exothermic energy (ca
l) can be easily known.

The heat storage body (1) is entirely surrounded by a heat insulating cushion material (2), and this cushion material (2)
The upper surface (2a), that is, the side in contact with the body, is thinner than the lower surface (2b) to facilitate the transfer of heat generated by the heat storage element (1) to the body.

The thickness of the cushioning material (2), in other words the heat insulating properties, is appropriately selected depending on the purpose and usage conditions of the heat.

For example, when warming the body at a low temperature for a long time, the upper surface (2a) is made thicker, and when the body is warmed at a higher temperature for a short time, the upper surface (2a) is made thinner. Note that in any of the above cases, the lower surface (2b) is required to have sufficient heat retention, so a sufficiently thick one is used.

As the cushion material (3) for the above-mentioned zafuton,
Polyurethane, which has both heat insulation and elasticity, is used. However, for other uses, heat insulation properties are usually given priority, and this heat insulation property allows the heat storage body (1) to have desired heat dissipation properties.

The cushion cover (3) is a bag made of cloth or vinyl leather, and at key points on its side there are zippers (8) for putting in and taking out the heat storage body (1) surrounded by the cushioning material (2).
) is provided.

Note that when putting the heat storage body (1) in and out of the cover (3), it is not necessarily necessary to take the heat storage body (1) in and out together with the cushioning material (2).
2) is placed inside the cover (3), and only the heat storage body (1) may be taken out and put in.

The cushion cover (3) is an example of the exterior body (A) of the hot sale container according to the present invention, and this exterior body (A) includes the following:
They come in various shapes depending on the purpose of heat use.

For example, the exterior body (A) may be shaped like a vest (9) as shown in Fig. 4 to warm the waist, or it may be shaped like a stuffed toy doll (10) as shown in Fig. 5 so that a child can hold it. You may also try warming their hands and chest.

Figure 2 shows an exterior body (A) used as an outer skin for a cushion cover (3), a vest (9), or a stuffed doll (10).
This figure shows the appearance of the heat storage body (1) inserted into the heat storage body (1).

This heat storage body (1) can be used as a cushion cover (3) or a vest (9).
), and a label (11) indicating the contents of the sale item is affixed to the appropriate place.

The label (11) shows the amount of heat (cal) that can be taken out from the heat storage body (1) that has sufficiently stored heat, the temperature of the heat storage body (1) that ensures sufficient heat storage, and the name of the substance of the heat storage material (6). , the weight (g) of the heat storage material (6), the melting temperature (melting point °C), the heat of fusion (cal/g), etc. are written.

In addition, a liquid crystal temperature display section (1
2) is provided, and this liquid crystal temperature display section (12)
is, when the heat storage material (6) is at a temperature higher than the melting temperature,
The required color indicates that sufficient heat is being stored.

For example, if the melting point of the heat storage material (6) is 55°C, the liquid crystal temperature display section (12) will display a liquid crystal display that turns red at 60°C or higher, blue at 50°C or lower, and purple at 50° to 60°C. Use.

Thereby, when the liquid crystal temperature display section (1z) exhibits a red color, it can be confirmed that heat is sufficiently stored in the heat storage material (6). As a result, while the heat storage material (6) is being cooled to a temperature below the melting point of 55°C, at least the heat storage material (6)
It can be seen that the amount of heat (cal) generated is equivalent to the product of the weight of the product and the heat of fusion per duram (cal/g). For example, 1
00g of polyethylene glycol.

This will generate at least 450 cal of heat.

The heat storage body (1) also contains a considerable amount of heat due to specific heat, but the amount of heat due to specific heat is very uncertain, so when selling heat, it is difficult to express it quantitatively or to express its amount. It is difficult to guarantee. Therefore, it is desirable to exclude the amount of heat due to specific heat from being sold.

A large number of the above-mentioned heat storage bodies (1) are prepared as a unit, and a large number of exterior bodies (A) are also separately prepared, and when selling heat, these are appropriately combined to form a heat sales container. formed and provided to consumers.

To sell heat, use an appropriate heating means to heat the heat storage body (1) until the liquid crystal temperature display section (12) of the label (11) indicates a temperature equal to or higher than the melting point, and then, The heat storage body (1) storing heat is surrounded by a heat insulating material (2) and placed in an exterior body (A), for example, a cushion cover (3),
Close the zipper (8).

When charging the heat storage body (1) that has stored heat into the exterior body (A), the heat consumer should check the liquid crystal temperature display section (11) of the heat storage body (1) before it is loaded into the exterior body (A). ), it can be confirmed that the required amount of heat is stored in the heat storage element (1).

As illustrated in Fig. 4, the exterior body (A) is attached to the vest (9).
When wearing it, a pocket (14) with a zipper (13) is provided in the part that hits the waist when worn, and the heat storage body (1) with heat stored is placed in the pocket (14) with a heat insulating material ( It is best to wrap it in 2).

As illustrated in FIG. 5, when the exterior body (A) is made into a stuffed toy doll (10), a fastener (15
) is preferably provided, and the heat storage body (1) can be taken in and taken out by opening and closing this fastener (15).

In addition, in the case of a stuffed toy doll (10), etc., the shape retaining material such as panda or urethane foam stuffed therein may be used as the heat insulating material (2).The heat storage body is shown in (1') in Fig. 3.
It may also have a cylindrical shape as shown in .

Next, a method of handling the above hot sales container will be explained.

■ After extracting and using the heat stored in the heat sales container, the heat storage body (1) and the exterior body (A) are separated.

■ To sell heat, stand outside, heat storage body (1) and exterior body (
A) is suitably combined, the heat storage body (1) is heated as required, and the required amount of heat is stored.

■ Wrap the heat storage body (1) with the required insulation material.

The container is charged into the outer package (A) to form a container for hot sale.

■ It can be used as a warming device to gradually remove heat from a heat sales container that has accumulated heat and keep the body warm.

According to this handling method, the heat storage body (1) and the exterior body (1) are handled separately until just before the container for hot sale is formed, so there is no need to store heat in the heat storage body (1)! Various heating methods can be applied in order to easily store heat in the heat storage body (1).

For example, means such as dielectric heating similar to a microwave oven, heating in a water bath in which the material is heated by placing it in high-temperature water, and heating in a hot room at a temperature higher than the melting point of the heat storage material (6) may be employed.

Furthermore, after being used as a container, the outer packaging (A) is
To provide a container that can be easily subjected to purification treatment such as sterilization, disinfection, and cleaning separately from the heat storage body (1), and in which heat is stored repeatedly in a clean state to an unspecified number of users. Can be done.

Next, a method of using the hot sale container according to the present invention will be explained based on the process diagram shown in FIG. 6.

Although a large number of heat storage bodies (1) and a large number of exterior bodies (A) are prepared, these numbers do not need to be the same, and there may be multiple types of exterior bodies (A).

A large number of heat storage bodies (1) are prepared separately from the exterior body (A) at required locations in the heat storage step (16).

A large number of various types of exterior bodies (A) are prepared at required locations in the container forming step (17).

In the heat storage step (16), each heat storage body (1) is heated to a temperature higher than the melting point of the heat storage material (6) by a heating means (18) using one of the various heating methods described above, and is heated to a temperature higher than the guaranteed amount of heat. Heat is stored.

In the container forming step (17), each heat storage body (1) that has stored heat is wrapped in a required heat insulating material (2) and placed in an appropriate exterior body (A), thereby forming a container for heat sales. be done.

The container for heat sales including the heat storage body (1) in which heat is stored is supplied to the consumer in the heat use step (19).

The containers that have lost their latent heat due to the heat used are recovered in a container recovery step (20), and the recovered containers are sent to a separation step (20).
21), the heat storage body (1) and the exterior body (A) are separated.

A large number of heat storage bodies (1) sorted in the separation step (21) are sent to required locations in the heat storage step (16).

The outer packaging (A) separated in the separation step (21) is further sorted by type, and is sterilized, disinfected, and disinfected in the purification step (22).
After cleaning, etc., the container is sent to a required location in the container forming step (17).

According to this usage method, the large number of heat storage bodies (1) and the large number of exterior bodies (A) do not have a specific correspondence relationship;
When the heat is stored, they can be used in appropriate combinations, so it can be used in a variety of sales formats.

〔Effect of the invention〕

(1) The heat sales container of the present invention is convenient for using heat because it is formed by storing heat in a heat storage body and then combining this with a suitable exterior body.

(2) Since the heat storage body stores heat as latent heat, the amount of heat to be sold is guaranteed, and the amount of stored heat can be transferred to the consumer when the heat storage body is attached to the exterior body, that is, immediately before heat sales. It is also possible to confirm.

(3) According to the method of handling the heat sales container of the present invention, the heat storage body and the exterior body are separated except when the heat stored in the heat storage body is used, so when selling the heat, the heat storage body and the exterior body are separated. To,
