DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for producing hot water, and more particularly to a method and apparatus for producing hot water by effectively utilizing coffee slag disposed of as waste.

[0002]

2. Description of the Related Art Conventionally, coffee scum (squeezed scum from which coffee is extracted) has been treated as waste, such as amortized disposal or landfill disposal, or mixed with soil and fermented to produce organic fertilizer. I have.

[0003]

By the way, the present inventor has found that a large amount of fermentation heat is generated from coffee grounds in the process of producing organic fertilizer by fermenting coffee grounds. In particular, they found that if only coffee grounds were piled up, the temperature inside the pile of coffee grounds alone would reach about 60 ° C., and this state would last for more than six months.

Therefore, an object of the present invention is to produce hot water by effectively utilizing the fermentation heat generated from the coffee grounds.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, a method for producing hot water according to the present invention is to accommodate a water storage tank having a large number of pipes extending in a housing, and to form a gap in the housing. The portion is filled with coffee grounds, water is supplied into the water storage tank, and the temperature is raised by the heat of fermentation by the coffee grounds and taken out.

According to the method for producing hot water of the present invention, a large number of pipes function as heat exchangers, and the temperature of the water in the pipes can be raised by fermentation heat generated from coffee grounds. And the water thus warmed circulates through the piping and the water storage tank by natural convection, and can convert the water in the water storage tank into hot water. If hot water produced by using the fermentation heat of coffee grounds is taken out in this manner, hot water can be naturally obtained without supplying energy such as electric power from the outside such as an electric water heater. Here, the fermentation heat at which the coffee residue is generated is about 60 ° C. according to the experiment of the present inventors,
Moreover, this temperature did not decrease even after more than half a year. Therefore, according to the hot water manufacturing method of the present invention, hot water can be manufactured for a long period of time without supplying energy. In addition, although coffee residue is waste, the scent of coffee does not have an unusual odor such as garbage, so it does not require electric power or gas at home and stably removes the warm water required for housework without discomfort. Can be supplied.

A water heater according to the present invention, which has been made to achieve the above object, has a water storage tank capable of storing water therein, and extends from the water storage tank to allow water to pass therethrough. A large number of pipes, a water supply port for supplying water to the water storage tank, a hot water outlet for taking out hot water from the water storage tank, a main body housing for accommodating the water storage tank and the pipe, And the coffee scum to be filled in the gap between the two.

According to the water heater of the present invention, the water is filled from the water supply port into the water storage tank and the pipe, and the coffee scum is filled in the gap in the housing, thereby generating the coffee scum. Warm the water in the pipe with fermentation heat,
The water thus warmed circulates naturally in the water storage tank and pipes by convection, and reduces the water in the water storage tank and pipes by about 6%.
The temperature can be raised to 0 ° C. The hot water thus obtained can be taken out of the hot water outlet and used for housework at home or as a heat source for heating. Even here, even if the coffee residue is waste, it does not emit an unpleasant off-flavor such as garbage, so that the user can obtain hot water without discomfort and at low cost. Further, since the fermentation heat of the coffee residue is obtained continuously over a long period of time, maintenance is easy.

Further, in the water heater according to the present invention, the water supply port is provided with an automatic water absorbing device for supplying substantially the same amount of water as the amount of hot water taken out from the hot water outlet at the time of taking out hot water. Can be configured as such.

According to this water heater, the same amount of hot water taken out from the hot water outlet is automatically supplied into the water storage tank by the automatic water absorbing device, so that the required amount of hot water is always supplied. Can be secured. In addition,
As an automatic water supply device, for example, using a float,
This can be realized by a simple structure such as automatically detecting a decrease in the water level, opening the water absorption valve, and closing the water absorption valve when the water level rises.

Here, the water heater of the present invention further includes a partition for disposing the housing in a state where a part of the pipe is circulated, and a fan for taking out hot air from a portion partitioned by the partition. Can also be configured.

According to the water heater provided with this fan, the heat generated from the piping can be taken out as hot air, and can be used for various types of heating.
