Description Portable heating engine device and cooking container using it (Technical field)

TECHNICAL FIELD The present invention relates to a portable heating engine device that generates hot steam by the heat of hydration reaction between calcium oxide and water, and a heating cooking container using the same.

'' (Conventional technology and its problems)

Various heating devices have been proposed as heating devices that utilize the heat of hydration reaction between oxidizing power and water.

That is, Japanese Patent Laid-Open No. 58-134 882, Japanese Utility Model Application No. 61-36563, Japanese Utility Model Application No. 61_106680, Japanese Utility Model Application No. 61-] 3 7-3 18 No., 'Michiran Sho 62-1 2 3 7 42, Shokai Sho 63-3 3 3 8 No., Shokai Sho 63-2 3271, No. There is a heating device described in No. 63-3-1911.

However, in these devices, firstly, the hydration reaction between calcium oxide and water proceeds rapidly, and bumping and the like are likely to occur. It has not been.

Second, no attempt has been made to ensure uniform contact between water and oxidizing water so that unreacted portions do not remain in calcium oxide.

Thirdly, calcium oxide is so dense that it does not absorb moisture before the hydration reaction. Although it is necessary to seal, the sealing bag is not devised so that the sealing bag does not hinder the contact between the sealed form of calcium oxide and the sealed water.

Fourth, calcium oxide and water are sealed separately, but their sealing bags must be opened at the same time in order to start their hydration reaction, but they are devised to ensure that they are opened. No: Fifth, food is heated using hot steam generated by the above hydration reaction, but no measures are taken to prevent anything other than water vapor from adhering to the food.

Sixth, since these heating devices are disposable, practically, it is necessary to produce them at low cost without exceeding the added value of the food to be heated. - Absent.

Therefore, there is a problem in terms of function and cost, and there is a problem that none of the devices are currently implemented and are not sold.

(Object of the invention)

Therefore, the present invention has conducted intensive studies and solved the above-mentioned problems. First, it was possible to control the hydration reaction between calcium oxide and water.

Secondly, the uniform contact between the water and the oxidizing water is performed. Third, the sealing bag does not hinder the contact between the sealed oxidizing water and the sealed water.

Fourth, the sealed bag can be simultaneously and reliably opened easily. Fifth, hot steam generated by the hydration reaction can be filtered. Sixth, the purpose of these heating devices is to provide a heating device that can be manufactured at low cost.

(Structure of the invention)

Therefore, the present inventor first uses, as the calcium oxide, powdered granules of the calcium oxide obtained by lightly baking quick lime, and as the reaction water, the water-soluble aluminum oxide is used. The use of earth metal chlorides, especially magnesium chloride, by dissolving about 0 to 50% by weight, and preferably 25 to 35% by weight, based on the weight of water, results in bumping. In addition, the inventors have found that the highest heat of hydration reaction is obtained, and that the hydration reaction in which the expansion coefficient of the oxidizing power is minimum is realized, thereby achieving the first object.

Second, in order to carry out the contact hydration reaction between water and calcium oxide, a method of permeating water from above the oxidizing power by gravitational fall of water is commonly used. However, in view of the fact that water does not uniformly come into contact with calcium oxide, water generated by absorbing water from below the calcium oxide and causing a hydration reaction from below the oxidizing power of calcium is considered. Expands and diffuses, and sequentially contacts the upper calcium oxide to achieve uniform contact.The second purpose was achieved.- Furthermore, third, calcium oxide was dissolved in the surrounding air. It is necessary to be sealed from the viewpoints of danger prevention and deterioration prevention because it easily absorbs moisture and reacts. However, if it is sealed, uniform contact with water may be impaired. Therefore, the initial hydration reaction is performed by sealing at least the oxidizing calcium in a heat-shrinkable resin bag. As a result, the bag surrounding calcium oxide was removed, and the third purpose was achieved.

In addition, the calcium oxide and the water must be simultaneously opened and contacted in order to cause a hydration reaction in which the calcium oxide and the water are sealed by the resin bags. Therefore, fourthly, in order to open the two bags reliably and easily, use a stretched film that is easy to tear as a bag film and cut at the beginning of the tearing direction. A mouth is formed, and the end of the thread means having one end fixed to the end in the cleavage direction is formed at the cut end, and the yarn is pulled toward the end in the cleavage direction. The fourth objective has been achieved.

Fifth, in order to filter water vapor, a filter sheet that allows only water vapor to pass through is placed at the top of the container that contains the sealed bag of calcium oxide and water. _c that in the No matter achieved fifth object: things以舛is arranged above .. adhere to the food to be heated: and the

Finally, a configuration for economically manufacturing a heating device having the above functions can be achieved by the following embodiments.
