Then, by operating the remote controller 61 to turn on the power, the solar panel 1 generates electric power, current flows to the battery B, and the battery B is charged. For this reason, the battery B is prevented from running out of battery and can be used continuously for a long time.

When the ignition switch of the remote controller 61 is operated, the pump P sucks the fuel in the fuel tank T and sends it to the burner unit 44. At the same time, the ignition transformer 45 converts the voltage from the battery B to a high voltage. Ignited.
The heat of combustion due to the combustion of the burner section 44 and the water to be heated (tap water) are heat-exchanged by the heat exchanger 42 and heated. By operating the remote controller 61 to set the temperature of hot water discharged from the shower and releasing the shower tap (not shown), hot water of the set temperature is discharged from the shower.

<When using at night>
When using the mobile hot water supply device A at night or in a dark place, the electric current from the battery B charged during the day is used to supply electric power to the electrical components such as the blower F in the boiler 4 to supply hot water. By carrying out, the mobile water heater A can be used for a long time.

  As described above, the mobile hot water supply apparatus A of the present invention can be used anywhere without worrying about the power source, even in the absence of power supply facilities, and in particular, camping sites, beaches, disaster sites and power sources. It can be used effectively as a hot water supply facility in a place where there is no facility.

[Modification]
The present invention is not limited to the above-described embodiment, and various modifications and changes can be made within the scope of the technical idea, and the present invention extends to these modifications and changes. Of course.

  In the said embodiment, although the mobile hot water supply apparatus A which uses kerosene as a fuel was mentioned as an example as an example of the boiler 4, it is not limited to this, The form of the boiler 4 is not specifically limited (refer FIG. 2). ). The boiler 4 may be, for example, a fuel using heavy oil other than kerosene, light oil, gasoline or gas. In that case, what is necessary is just to adapt the structure of the boiler 4 according to fuel.

  The link member 54 interposed between the base end portion 1a of the solar panel 1 and the frame portion 53 of the wagon 5 forms a link mechanism composed of a single arm 54a, 54b in side view. However, the present invention is not limited to this (see FIG. 2). The link member 54 may be formed by a plurality of arms 54a and 54b in a side view.

Moreover, in the said embodiment, as shown in FIG.2 and FIG.3, as an example of the link member 54, although the thing which fixed the length of a pair of left and right arms 54a and 54b was described as an example, It is not limited.
For example, the link member 54 may be formed such that the arms 54a and 54b are made of a stretchable member so that the length thereof can be varied, and the inclination angle θ of the solar panel 1 can be adjusted according to the position of the sun. I do not care.
If the arms 54a and 54b are formed in this way, the inclination angle θ of the solar panel 1 can be increased by extending the arms 54a and 54b, and the inclination angle of the solar panel 1 can be reduced by contracting the arms 54a and 54b. Since θ can be reduced, the light collection efficiency of sunlight can be improved.
