Description

  The present invention relates to a heater for storing heat.

Conventionally, there is a hot water bottle (a hot water bath) as a heater that warms the body by touching the periphery of the body. There are hot water bottles that pour hot water into containers, put them in a futon, etc., mainly warm your feet, and warm your feet and hips in the back and feet of chairs. Container materials include pottery, metal, and plastic. Because temperature control does not work, you may get burned if you do not wrap the cloth during use, or the cap may loosen during use if you do not tighten it securely. In addition, low temperature burns (hereinafter referred to as low temperature burns) may occur at high temperatures. In addition, there are those that enclose azuki beans, buckwheat, gelling agents, natural stones, etc., warm them with a microwave oven, and warm the waist, shoulders and feet.

Since these heating appliances are gradually cooled after warming the main body, it is difficult for the body to be burdened with electrical appliances that maintain a constant temperature.
Conventional hot water bottles were troublesome to boil hot water and pour hot water, but the plastic container type became more convenient by heating with a microwave oven, etc. In addition, problems such as low temperature burns due to long-term use while hot are occurring. Since hot water gradually cools, humanity tends to pour hot water at a high temperature, which also causes accidents.

According to Patent Document 1, “the heater inside the electric fire is automatically switched between strong and weak, or the temperature characteristic of the hot water bottle is input inside the electric fire.” It is an electric anchor that incorporates the characteristics of
In this way, there was no device that can be warmed at a constant temperature for a long time with peace of mind, gentle to the body without touching low-temperature burns, and able to warm while touching the surroundings. For this reason, it is thought that the apparatus using a heat storage material or a latent heat storage material will be used in the future. It is considered that these instruments are basically made of a flexible container. At this time, there is no concept of a method for preventing internal liquid leakage by overlapping the number of these flexible containers, or a method for improving the safety by making it easy to detect liquid leakage.

Japanese Patent Publication No. 9-257255

Conventional hot water bottles are cumbersome because hot water must be added, and there is a danger associated with handling hot water. In addition, the plastic container type is troublesome to forget to open the cap when it is heated in a microwave oven. There was also a problem of hot water leakage due to loose caps. Electric hot water bottles, red bean paste, blankets, etc. have weaknesses such as electric accidents, resistance to wearing electricity, and weakness such as autonomic nerves by maintaining a constant temperature.
Therefore, a hot water bottle for a heating appliance using a heat storage material using latent heat or the like is conceivable. For example, low temperature fever can be avoided by storing heat in hot water in the bath. In a hot water storage material container for a hot water bottle of a heating appliance that uses this heat storage material, when the internal heat storage material leaks due to damage to the container or the like, leakage of the contents occurs.

  In order to solve the above-mentioned problems, a liquid leakage prevention heat storage type hot water bottle according to an aspect of the present invention is a heat storage type hot water bottle in which a heat storage material is sealed inside a bag-like container. It is characterized in that it is easy to visually check the leakage of the internal heat storage material by covering it heavily, increasing the strength, and making the outer container member transparent or translucent.

It is said that low temperature burns are damaged in about 6 to 10 hours when the temperature of the contact part is 44 ° C., and it is said that the time for receiving damage may be shortened as the contact temperature rises between 44 ° C. and 51 ° C. ing.
In contrast to sensible heat storage that uses the specific heat of a substance, the technology that stores the latent heat exchanged with the outside as a thermal energy during the phase change or transition of the substance is called latent heat storage. Typical examples include ice (water), paraffin, inorganic salts, and the like, and use the heat of fusion at their melting point and the heat of freezing at the freezing point. Since these materials involve a phase change between solid and liquid, the material used for latent heat storage is called PCM (Phase Change Materials).
The latent heat storage material can store about 5 times the amount of water per unit volume and about 10 times that of concrete.
For this reason, the regenerative hot water bottle of the present invention stores heat by putting it in the bathtub, and since it is simply taken out and used, it generates a large amount of heat even with a small body weight, and it is simple and environmentally friendly. For example, by placing it under the foot of a futon on a cold night, it becomes a heat storage hot water bottle that can sleep comfortably until morning without causing low-temperature burns. In addition, a heat storage hot water bottle using a heat storage material can be placed inside a cushion-like shape and placed on the knee, or a foot or a pocket for inserting a hand can be provided to warm the limb. Furthermore, it can be used as a cushion.
According to the present invention, these heat storage type hot water bottle containers are prevented from being damaged, and it is easy to detect leakage of the contents (liquid) containing the heat storage material at the time of the damage, thereby providing safe and comfortable use.

It is a top view of the Example which enclosed the heat storage material inside. It is a part of sectional drawing of the Example which enclosed the thermal storage material inside. It is a part of sectional drawing which enclosed the heat storage material inside and put the solution between containers.

  Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a heat storage type hot water bottle of the present invention that prevents liquid leakage.
The heat storage type hot water bottle 1 is a heat storage material 3 in which a bag-like container 2 is doubled and enclosed. Specifically, the bag-like container 2 is formed by sealing the outer periphery of the four sheets and the bonding surface of the bag with the welding surface 2a, providing the handle portion 2b, and forming the bag-like container, A heat storage material 3 is enclosed in a sheet material (inside the inner bag).

2 (a) and 2 (b) show a part of the front cross-sectional view of FIG. 1, showing a doubled sheet material of a bag-like container. FIG. 2B shows a state in which the sheet material of the inner bag-like container 21 is broken and liquid leakage occurs. For example, the sheet material of the outer bag-like container 22 is made of a transparent material, and the sheet of the inner bag-like container 21 is made of an opaque orange color. Moreover, the heat storage material enclosed inside is made up of black including carbon and the like. In such a state, the sheet material of the outer bag-like container 22 is transparent when a liquid leak occurs from the inside, so that the damaged portion 4 of the inner bag-like container is the sheet of the inner bag-like container 21. Black content leaks over (orange). For this reason, it becomes easy to visually check the leakage of the contents. Further, at this time, the outer bag-like body is not torn and no leakage to the outside occurs, so that safety can be maintained. In addition, the latent heat storage material becomes a lump during solidification, and when an impact is applied to the bag-like container, there is a high probability that the inner bag-like container is damaged. By duplicating the bag-like body in this way, it is possible to reduce the probability of breakage of the same location at the same time in each bag-like container.

In this case, the bag-like container was welded simultaneously with each sheet material, but the outer bag-like container may be sealed after the heat storage material is sealed in the inner bag state.
A non-phthalic acid type vinyl chloride sheet material is suitable for the bag-shaped container. The inner material and the outer material of the bag-like body may be changed in thickness of the sheet material. Further, the hardness of the sheet material may be changed. Furthermore, other flexible sheet materials such as polyethylene and polyurethane may be used as the sheet material. Furthermore, it may be molded with a plastic resin such as polypropylene or ABS, and the heat storage material sealing port may be sealed. In addition, the outer bag-shaped body may be sealed with a flexible sheet material to form an outer bag-shaped body container.
Adhering the seams of the outer bag-like container and the inner bag-like container and excluding air from the contents is effective for expediting the appearance and the discovery of damage.

FIG. 3 shows a part of a sectional view in which a heat storage material is enclosed and a solution is put between containers.
In detail, the one in which the solution 5 is placed between the outer bag-like container 22 and the inner bag-like container 21 is shown. For example, the solution 5 is not only the damaged portion 4b of the inner bag-like container but also the outer bag by placing colored water with high safety, good discoloration, water in which the pigment is dissolved, or alcohol. The breakage point 4a of the container of the solid body can be soaked in the color of the solution to confirm the breakage. Further, by putting an odorous substance having an odorous property such as ammonia or a mixture thereof in the solution 5, it is possible to feel the odor and detect the damage. The odor substance may be a mint-based or menthol-based fragrant material.
