Description

[Detailed Description of the Invention] This invention is a cooling room in which a cremation cart can be placed, which is provided between a crematorium of a crematorium and a decorative door in front of the crematorium. This device cools the cremation cart by sucking in cool air (air at room temperature or air cooled by a cooler).It efficiently cools the cremation cart in a short time, and also prevents the remains and ashes on the cremation cart from leaving the cart during cooling. The purpose is to provide cooling without being scattered.

In recent years, crematoriums are often built far away from urban centers, and as traffic increases and congestion occurs, bereaved families tend to wait at crematoriums until their bones can be collected. There has been a desire to shorten cremation time. Therefore, solutions have been proposed in Japanese Patent Publication No. 56-8244 and Japanese Utility Model Publication No. 13466/1983. In the device disclosed in the above-mentioned publication, a cooling stand is provided in the cooling chamber between the vanity door and the crematorium, and a hood connected to an exhaust duct is provided above the crematorium placed on the stand. By applying the cooling air ejected from the platform to the underside of the cremation cart and applying intake force to the exhaust duct with the intake device, the cooled air rises from the bottom of the cremation cart, licks the top surface of the cremation cart, and flows into the duct. It is for cooling.

In addition, the cooling according to the Jikkosho publication is similarly carried out in a cooling chamber installed between the vanity door and the crematorium, and an exhaust hood is installed in the upper part, and the air is emitted from the side to the top of the crematorium. It is configured to be cooled by cooling air.

In both of the above-mentioned publications, cooling air is ejected horizontally to the top of the crematorium to cool it in a licking manner, and compared to natural cooling, it is natural that the efficiency is doubled because it is forced cooling. However, when an object is hot, there is a layer of hot air on the surface of the object, and cooling air is ejected from a direction perpendicular to the surface of the object, rather than when the object is licked by a cooling air current. By applying heat, the hot air layer is destroyed more quickly and the cooling rate can be further increased, and generally the heat is reduced seven times faster. However, even if such a cooling effect can be obtained, in the case of a cremation cart, cremated ashes are placed on the cart, and if it is ejected from a right angle, the ashes will scatter. I couldn't think of any other solution other than to cool it down by licking it like in the official bulletin.

This invention was developed based on further research based on the above points, and was devised to cool the crematorium by blowing out cooling air from above, and to prevent remains and ashes from being scattered. Cover the crematorium closely with the outer hood, and suspend the inner hood within the outer hood so that it does not touch the top of the cremation cart.
It is characterized in that the cooling air is blown out from the inner hood toward the upper surface of the cremation cart and exhausted from the gap between the outer hood and the inner hood.

Hereinafter, an embodiment according to the present invention will be described with reference to the drawings. A crematorium 4 is installed behind a decorative door 2 provided in an opening of a partition wall 1 in a crematorium with a space in which a crematorium cart 3 can be placed. A cooling chamber 5 is formed between the crematorium 4 and the decorative door 2, and the heated cremation cart 3 taken out from the crematorium 4 is cooled in the cooling chamber 5. The mounting table 6 installed in
A rail 7 on which the cremation cart 3 runs is laid on top, and the cremation cart 3 is moved from the mounting table 6 into the crematorium 4 and from the inside of the crematorium 4 to the mounting table 6 by a drive device 8, The limit switch 9 is controlled to stop the cremation cart 3 at a predetermined position on the mounting table 6, and since the present invention does not relate to the movement and control of the cremation cart 3, a detailed explanation thereof will be omitted.

Therefore, the cooling device is provided in the cooling chamber 5, and an outer hood 10 having a size that covers almost the entire upper surface of the cremation cart 3 is provided in the upper part of the cooling chamber 5 so as to be movable up and down. Almost the entire top surface of the cremation cart 3 means that the cremation cart 3 generally has a high outer periphery on the top surface and a low central part (the part where the coffin is placed) is recessed, as shown in the figure, and the outer hood 10 covers the central part. Indicates the size required to cover the entire surface. This outer hood 1
A skirt 11 made of a heat-resistant and flexible material such as heat-resistant floss is fixed around the lower end of the outer hood 10, and when the outer hood 10 is lowered, the skirt 10
is in contact with the upper surface of the cremation cart 3. Also,
The outer hood 10 has an exhaust port 12 at the upper end leading to an exhaust duct 13, and a lifting device 14 such as a winch.
The exhaust duct 13 is provided with an extendable part 15 that can move up and down, and the exhaust duct 13 is further provided with a dust remover 16 and a heat sensitive element 17 such as a thermocouple.

Inner hood 1 for air supply inside the outer hood 10
8 is hung from the outer hood 10 at a distance from the inner surface of the outer hood 10, and the lower surface of the inner hood 18 is positioned higher than the lower surface of the outer hood 10. At the upper end of this inner hood 18 is an air supply port 1 that leads to an air supply duct 20.
9 is open, and a plurality of rectifying plates 21 are provided inside the inner hood 18 to adjust the direction of air supply, and furthermore, a dust collecting groove 22 whose upper part is open is formed on the outer peripheral edge of the side surface of the inner hood 18. There is.

The combination of the outer hood 10 and the inner hood 18 is as shown in FIG. The inner hood 18 is fixed and the air supply duct 20 is connected to the inner hood 18. Alternatively, as shown in FIG. 3, insert the air supply duct 20 into the exhaust duct 13 from the middle part of the exhaust duct 13,
An outer hood 10 is connected to the exhaust duct 13, and an inner hood 18 is connected to the air supply duct 20. Like the exhaust duct 13, the air supply duct 20 is also formed to be expandable and retractable. In addition, the air supply duct 20 is a blower 2.
3 through a damper 24, or a cooler 25 is provided in the middle. Furthermore, when a predetermined temperature is reached by the heat sensitive element 17, the blower 2 is activated.
3 is configured to be controllable to stop.

This invention has the above structure, and the cremation cart 3 pulled out from the crematorium 4 is placed in the cooling chamber 5, the outer hood 10 is lowered and the skirt 11 is brought into contact with the upper surface of the cremation cart 3, and then the blower 23 is placed in the cooling chamber 5. When the cooling air is injected from the inner hood 18 by driving the cooling air, the cooling air is supplied from above the cremation cart 3, so the cooling air hits the top surface of the cremation cart 3 almost at right angles, and the hot air that has been heat exchanged is is inner hood 18 and outer hood 1
0 and is discharged from the exhaust duct 13. As a result of the experiment, the following data was obtained, clearly demonstrating the superiority of cooling efficiency.

The surface temperature of the cremation cart immediately after cremation in the crematorium is approximately 700-750℃.The surface temperature of the cremation cart when taken out of the crematorium and placed in the cooling room is approximately 680-700℃. The time it takes to cool down to a temperature of 100 to 150 degrees Celsius that allows bones to be collected is: in the conventional case...15 to 20 minutes; in the case of the present invention...5 to 8 minutes. Approximately 20-30
It is ℃.

The cooling device according to the present invention has an inner hood suspended within an outer hood at a distance from the inner surface of the outer hood, a skirt provided at the lower edge of the outer hood,
An air supply duct is connected to the inner hood, and an exhaust duct is connected to the outer hood. Cooling air ejected from the inner hood is applied to the top of the cremation cart from above, thereby cooling the hot air layer on the surface of the cremation cart. Since it is rapidly destroyed by the jet force of air, the cooling efficiency is further doubled. Furthermore, since the cooling air jetted by the skirt is prevented from dissipating outside the crematorium, the remains and ashes will not be scattered during cooling, and the cooling process will be carried out extremely well.
