Description

[Detailed Description of the Invention] This invention relates to a heating device, and particularly to a heating device that heats a liquid material by utilizing a chemical exothermic reaction.

Conventionally, in order to heat food and drink, such as coffee and alcohol, to a temperature suitable for eating and drinking, the food and drink were usually placed in a heat-resistant container and heated with a heat source such as gas or electricity.

However, for example, in families with infants, milk for infants must be given at regular intervals.
It was extremely troublesome to heat the milk each time.

In addition, when going out for mountain climbing, fishing, etc., and heating the above-mentioned food and drinks outdoors, it is necessary to carry a portable heat source, which is not only troublesome, but also poses a constant fear of fire and other dangers. By the way, it was hot.

For this reason, various heating methods using chemical reactions such as compounds that generate heat through hydration reactions and metals that generate heat through oxidation reactions have been studied, but these methods have drawbacks in terms of calorific value and safety when eating and drinking. The reality is that it has not yet been put into practical use.

This invention was developed in view of the above background, and its purpose is to have a relatively simple structure, be convenient to carry, and be able to be used in a short period of time without the risk of fire or other hazards. An object of the present invention is to provide a heating device capable of heating a liquid substance to a certain temperature.

Hereinafter, preferred embodiments of this invention will be described based on the accompanying drawings.

FIGS. 1 and 2 show an embodiment of the heating device according to this invention.

The heating device shown in the figure has quicklime 10 inside,
A bag-shaped container 1 that stores a small bag 14 in which water 12 is sealed and has an outside air communication port 16 formed approximately in the center of the upper end.
It is roughly composed of 8.

It is preferable that the quicklime 10 be in the form of a lump or a compression molded product of 2 to 10 meshes to allow for smooth hydration reaction and volume expansion. The amount of water 12 is set to the amount necessary for the hydration reaction of quicklime 10. Above outside air communication port 1
Reference numeral 6 is for discharging the expanded air in the container 18 to the outside during the hydration reaction of the quicklime 10. In this embodiment, a rod 20 for breaking the small bag 14 is provided inside the container 10, and a cap 22 is provided at the upper end. It is attached by screwing it on for convenience during use, but
The rod 20 does not necessarily need to be attached.

The container 18 is made of relatively thin aluminum,
A more preferable metal foil is used in this embodiment, which is made of metal such as copper, iron, or plated materials.The front and back surfaces of this metal foil 18a are coated with a synthetic resin film such as polyethylene or a nonwoven fabric. The lower end is sealed by welding or thermocompression bonding, and the upper end is similarly sealed except for the communication port 16.

In this case, the reinforcing members 18b, 18b may be attached to only one of the metal foils 18a, and furthermore, as shown in FIGS.
c is formed, and this through-hole portion 18c is pasted.
The surface of the metal foil 18a is exposed from the quicklime 10.
It is also possible to improve the transfer efficiency of hydration reaction heat.

Forming the through holes 18c as described above is necessary in the case of a synthetic resin membrane having relatively poor thermal conductivity, but when the reinforcing member 18b is made of a porous material such as a nonwoven fabric, the thermal conductivity is It is not necessarily necessary since it is not inhibited.

The outside air communication port 16 can be formed, for example, by arranging the cylindrical body 19 in advance so as to protrude into the container 18 as shown in FIG. For example, the upper end welded portion of the container 18 may be connected to the outside air communication port 16.
It can be easily formed by dividing it by removing the part corresponding to .

Next, how to use the heating having the above configuration will be explained.

First, as shown in FIG. 4, a cylindrical heat-resistant container 24
A liquid material 26 is stored inside the container, and the heating device is immersed therein.

In this case, care must be taken to position the outside air communication port 16 of the heating device further above the upper end surface of the liquid material 26, so that the quicklime 10
The expanded air inside the container 18 accompanying the hydration reaction can be discharged to the outside.

Examples of the liquid substance 26 include coffee, alcohol, sweet sake, etc. as long as it contains at least a liquid component.
These include liquid foods and beverages such as milk, baby milk, and soup, and foods and beverages containing solid content such as soup, ramen noodles, and miso soup.

Next, the cap 22 of the rod 20 installed in the outside air communication port 16 is removed and pushed down.

As a result, the pouch 14 housed in the container 18 is broken, and the water 12 inside is released and comes into contact with the quicklime 10 below.

Quicklime 10 in contact with water 12 undergoes a hydration reaction as is well known, releases a large amount of heat of reaction, and changes into slaked lime.

This reaction heat is transferred to the metal foil 18a with good thermal conductivity.
The heat is transmitted to the liquid material 26 that is in contact with the outer surface of the bag container, which is mainly made of , and is heated to a predetermined temperature.

In this case, as shown in FIG.
is stored in an outer bag 28 made of synthetic resin such as polyethylene, and this outer bag 28 is placed in the container 18.
It is also possible to seal them integrally by storing them inside.

Further, the means for breaking the pouch 14 is not limited to the above-mentioned method, but may include, for example, attaching a thread, a string, a rod, etc. to the pouch 14 and tearing it by pulling it upward; Alternatively, a sealing stopper is disposed in the pouch 14, and a string, string, or rod is connected to this stopper, and the stopper is removed by pulling it upwards or pushing it in the case of a stick, and the pouch 1
The water 12 in 4 may be released.

It goes without saying that the amounts of the quicklime 10 and the water 12 in the pouch 14 can be appropriately selected depending on the object to be heated, and can be increased or decreased.

In addition, if the amount of quicklime 10 is increased and there is a risk that the expansion force during the hydration reaction will become large and damage the container 18, the quicklime 10 may be placed in another container made of metal foil or a metal can with an open top. By storing it in a bag to create a double structure (as shown by the imaginary line in Figure 2), or by placing it in a net made of metal, synthetic resin, non-woven fabric, etc. and storing it in the container 18,
It can be reinforced relatively easily.

As explained above in detail in the examples, the heating device according to this invention uses the heat of the hydration reaction of quicklime to heat the liquid material to a predetermined temperature, so that the heating has a chemical exothermic effect. In addition to being carried out without the risk of fire or other hazards, a large amount of reaction heat can be effectively transferred to the object to be heated via a metal with good thermal conductivity, making it possible to heat the object to a specified temperature in a short period of time. can. In addition, the water used in the exothermic reaction is sealed in a pouch so that it does not come into contact with the quicklime until it is broken, and the container is sealed with a synthetic resin film attached to at least part of the surface or back of the metal. Alternatively, since it is reinforced with a reinforcing member made of non-woven fabric etc., it is protected from impact and is safe, and since it is built into the container, it can be made into a convenient form to carry, so there are no restrictions on location or time. It can be used without any problems.

Furthermore, the used heating device, which has changed from quicklime to slaked lime by releasing reaction heat, will not cause any pollution or other problems even if it is disposed of as is, but slaked lime has the advantage of being able to be used as fertilizer for plants.
