Description

Specification

Coffin cooling device and coffin cooling system

TECHNICAL FIELD The present invention relates to a coffin cooling device for cooling a coffin for storing a corpse and a coffin cooling system including the coffin.

Background art

If a person dies, the dead body is kept in the coffin in a casket for about 3 to 4 days by going through the night or holding a ceremony. Otherwise, decay proceeds and a dead odor is generated. Therefore, dry ice is usually placed in the coffin as a preservative for the body.

Also, for example, as described in Japanese Patent Publication No. Hei 9-930659, a liquefied gas supply space is formed in a coffin or mortuary storage bag, and a liquefied gas supply space is Supplied, the sterilization was performed while cooling the inside of the coffin or the body storage bag.

However, when dry ice is placed in direct contact with the body, the skin discolors, and at first glance it feels cold and feels pity on the body. Also, since dry ice disappears over time, it is necessary to replenish it appropriately, in which case you will have to remove all the dry ice bags in the coffin and pack new dry ice However, doing it face-to-face is a painful task.

Even during cremation, when dry ice is contained in the coffin, it takes a long time to reach a high temperature (for example, 800 ° C), and dioxin is generated. In the case of cremation, it is compulsory to remove elements that would produce dioxin from the coffin, but this has not been done in practice. Further, in the invention described in the above-mentioned publication, there is a problem in that an expensive liquefied gas is supplied, so that cost is increased. In addition, since carbon dioxide is used as liquefied gas, the carbon dioxide becomes snow-dried ice, and it takes a long time to reach a high temperature during cremation. Also, since carbon dioxide is considered to be a causative substance of the global warming phenomenon, there is a problem that it causes environmental destruction on a global scale.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coffin cooling device and a coffin cooling system that can efficiently cool the remains in a coffin without using dry ice or liquefied gas. And Disclosure of the invention

A coffin cooling device according to a first invention that meets the above object has a cooling member that comes into contact with or adheres to the bottom of the coffin placed on the top, and cools the bottom of the coffin by direct heat transfer from the cooling member. This cools the body stored in the coffin. The coffin is generally made of wood and has poor thermal conductivity. However, if the coffin is placed directly on or in close contact with the cooling member, the bottom (bottom plate) of the coffin is cooled by direct heat conduction from the cooling member. Furthermore, the tatami mats and futons above it are also cooled, and as a result, the corpse is gradually cooled. It takes a considerable amount of time to cool the inside of the coffin, but the inside of the coffin is shut off from the surrounding air by the wood that makes up the coffin itself.Furthermore, there is no air flow inside the coffin, so the heat from the bottom The inside of the coffin can be gradually cooled by conduction. Therefore, it is not necessary to provide special equipment for the coffin to be used, and it is not necessary to process holes.

In the casket cooling device according to the first invention, it is preferable that the cooling member is formed of a resin or a metal having good heat conductivity (for example, stainless steel, iron, copper, or brass). This makes it possible to increase the heat transfer efficiency of the cooling member, Can be cooled.

Further, in the casket cooling device according to the first invention, the cooling member may be cooled by electronic cooling means utilizing a Bertier effect. As a result, the coffin can be efficiently cooled and the size of the apparatus can be reduced.

In the casket cooling device according to the first invention, the cooling member may be provided on a ceiling of a mounting table on which the casket is mounted. This allows the bottom of the coffin to be placed directly on top of the coffin and efficiently cooled.

In the casket cooling device according to the first invention, it is preferable that the mounting table is provided with a heater, whereby when the casket cooled by the cooling member and the cooling member are frozen and cannot be separated from each other, the heat of the heater is not applied. Can also melt the ice. In addition, other than using only electric heater

This also includes the case where an electronic refrigeration unit utilizing the Peltier effect is used, and heat is generated by applying a current in a direction opposite to the direction of cooling.

In the casket cooling device according to the first invention, a fan for sending cool air is provided at the bottom of the cooling member, and cooling of the cooling member can be promoted.

Further, in the casket cooling apparatus according to the first invention, the refrigerant pipe may be provided directly inside the cooling member, and a refrigerator may be separately provided for circulating the refrigerant to the refrigerant pipe. As a result, the coffin can be efficiently cooled and the size of the apparatus can be reduced.

A coffin cooling system according to a second invention that meets the above object has a coffin and a mounting table provided with a cooling member that places the coffin on top and that is in contact with or in close contact with the bottom of the coffin. It cools the bottom of the coffin by heat conduction, which in turn cools the remains contained in the coffin. Thus, the bottom of the coffin can be efficiently cooled by the direct heat conduction from the cooling member, and the inside of the coffin can be cooled. Further, in the casket cooling system according to the second invention, the casket bottom and the cooling member are formed with a plurality of openings penetrating therethrough. A fan that blows in cool air is provided to cool the body by heat conduction and also to cool the body by convection. Thus, the inside of the coffin can be efficiently cooled by direct heat conduction from the cooling member and convective heat transfer from the opening of the coffin.
