Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a water heater suitable for use in a mortuary bathtub.

[Conventional technology]

In general, in Buddhist funerals, there is a custom of washing and purifying the body by bathing it in hot water before placing the deceased in the coffin.

Contrary to the usual method, with a hot water bath, you first fill a basin with water, pour hot water into it to create hot water of the appropriate temperature, place the body in the same vessel and wash it cleanly, dispose of the used hot water under the floor or in the toilet, and leave it in the sun. There is a habit of abhorring exposure to

By the way, at present, even if you try to bathe a corpse, there are no tubs or special tanks suitable for this purpose.
It is merely a formal process of wiping with a towel or hand towel, or using alcohol.

However, when using this method, not only is it not possible to thoroughly cleanse the corpse, but considering that bathing is a part of the funeral, it lacks solemnity and leaves problems for the feelings of the bereaved family. It will be.

Therefore, in order to solve the above-mentioned problems, the applicant has already proposed a mobile hot water tanker.

This hot water tank is made up of a movable cleaning tank, a water receiving tank, and a cleaning table that can be disassembled and assembled, and is transported to the destination using a transportation vehicle, and then set at the desired location. The corpse was placed on a cleaning table and placed in the clean tank, and hot water was supplied from the water heater installed in the car to the water discharge end of the clean tank. The bodies were washed and the dirty waste water was collected and collected in a water tank, which was then taken home and disposed of according to custom.

By using the above-mentioned hot water tank, it can be transported to homes, hospitals, and other required locations, where it can perform thorough hot water treatment easily and quickly, and without contaminating the area with waste water, etc. However, if you simply use the pump installed in the car to supply hot water to the water outlet, the water will inadvertently intensify and cause damage to the surrounding area. The pressure of the ejected water changes depending on whether the vehicle gets wet or the number of floors above the location where the hot water is being poured, making it difficult to adjust the water pressure to an appropriate level because the vehicle in question is far away from the location where it is used. .
