It is explanatory drawing which provides the explanation when using the portable heat exchange apparatus. It is explanatory drawing of the portable heat exchange apparatus which concerns on 2nd Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is an explanatory view of a simple bath system including a portable heat exchange device according to the same embodiment, FIG. 2 is an explanatory view of the portable heat exchange device, and FIG. 3 is a perspective explanatory view of a pipe member.

The simple bath system 100 includes a portable heat exchange device 1 according to the present invention capable of heating water supplied from a water source 101, a storage means 102 for storing hot water obtained by heating water in the heat exchange device 1, and a storage means 102. An external heat source 103 and a fuel storage means 104 for supplying fuel to be burned by the heat source 103 are provided. The water source 101 can also serve as the storage means 102.

The portable heat exchange device 1 includes a portable tubular housing (casing) 10 and a pipe member 20 arranged in the housing 10 and wound in a spiral shape through which water flows.

The lower end of the housing 10 has an opening 11 for taking in heat from an external heat source 103, and the upper end of the housing 10 has a lid member 12 arranged in the vicinity of the pipe member 20. There is. The lid member 12 is partially provided with a notch portion 12a.

The pipe member 20 is made of a member having a higher thermal conductivity than the housing 10, and uses, for example, a copper pipe. The pipe member 20 is wound without a gap in the winding direction. Further, the pipe member 20 is arranged with a gap 13 with respect to the inner wall surface 10a of the housing 10.

One end 21 of the pipe member 20 is pulled out (pulled in from the outside) at the upper part of the housing 10 and is pulled out from the water source 101 by a liquid feeding pump 40 as a liquid feeding means via a liquid path 111 or the like. Water is supplied. The other end 22 of the pipe member 20 is drawn out at the lower part of the housing 10 and is connected to the storage means 102 through a liquid path 112 or the like, and warm hot water is discharged.

As the heat source 103, for example, a single burner that burns vaporized fuel such as gas or petroleum can be used. The simple hot water supply system 200 is composed of the heat exchange device 1 and the heat source 103.

Next, the operation of this embodiment will be described with reference to FIG. FIG. 4 is an explanatory diagram provided for explaining the same operation.

When using the simple bath system 100 according to the present embodiment, one end 21 of the pipe member 20 of the heat exchange device 1 is connected to a liquid feed pump 40 that feeds water from the water source 101 via a liquid path 111 or the like. .. Further, the other end 22 of the pipe member 20 of the heat exchange device 1 is connected to the storage means 102.

Further, as shown in FIG. 4, the housing 10 of the heating device 1 is placed on the trivet 106, and the heat source 103 is arranged below the opening 11 of the housing 10. The trivet 106 may be integrated with the heat source 103.

In this state, by burning the vaporized fuel or the like from the heat source 103, the heat generated by the flame 105 enters the housing 10 and heats the spirally wound pipe member 20 from the inside, so that the heat flows through the pipe member 20. Water is heated (heat exchanged).

At this time, since the upper opening of the housing 10 is covered with the lid member 12, the pipe member 20 is efficiently heated. Further, the lid member 12 is partially provided with a notch portion 12a to prevent the inside of the housing 10 from becoming oxygen deficient, so that the pipe member 20 is heated stably and efficiently.

As a result, the warmed water is discharged from the other end 22 of the pipe member 20 and stored in the storage means 102 such as a bathtub.

According to the experiment, 80 liters of water could be heated to an appropriate temperature and stored in the storage means 102 in about 1 hour.

In this way, the portable heat exchanger 1 is portable, and if there is a heat source 102 such as a single burner and a fuel 104, it becomes possible to warm water and supply hot water, and it is possible to easily supply hot water with a simple configuration. It can be performed.

Further, by warming the lid member 12, food and drink can be warmed on the outer surface of the lid member 12.

Next, the second embodiment of the present invention will be described with reference to FIG. FIG. 5 is an explanatory diagram of the heat exchange device according to the same embodiment.

In the present embodiment, an outer lid member 50 that covers the opening is provided on the upper portion of the housing 10.

As a result, the outer surface of the lid member 12 can be prevented from being exposed. Further, by making the outer lid member 50 removable, the outer surface of the warming lid member 12 can be used or closed.
