Although the discharge hose 11 is drawn short in the drawing, it is not limited to this, and it may be 1 m to 3 m in use.

A heat source 13 such as an open fire is arranged below the heating tube body 5 to heat the spiral wound portion 5c of the heating tube body 5 . The heating tube body 5 is shown mounted on the mounting table 14 . The upper surface of the mounting table 14 is composed of a mesh body 14a shown in FIG. 5 or a mesh body 14b shown in FIG. When the heat source 13 is an open fire, the open fire is set on the heat source base body 15, and the spirally wound portion 5c of the heating tube body 5 is heated by the flame of the open fire.

Next, a description will be given of the operation of taking a bath using the portable bathing apparatus outdoors, camping, or the like.

First, it is necessary to store water in a portable bathtub 1 installed near a river. The water in the brought tank is poured into the portable bathtub 1 to a water level at which the user can take a bath. However, it is necessary to bring many water tanks of 20 liters to 40 liters, which is considered to be practically difficult.

Therefore, it is conceivable to use a small pump 10 . One side 11a of the discharge hose 11 connected to the discharge port 10b of the small pump 10 is removed. Then, one side of a hose for drawing water from the river is connected to the water intake portion 10a of the small pump 10, and after the other side of the hose is immersed in the water surface of the river, power is supplied from the battery 12 to power the small pump. 10 is driven to pump river water from the other side of the hose to the water intake part 10a of the small pump 10 on one side, and pump it into the portable bathtub 1 from the outlet part 10b of the small pump 10, until the water level reaches a bathable level. The small pump 10 is operated.

When water is pumped into the portable bathtub 1 to a bathable level, power supply from the battery 12 is stopped to stop the small pump 10. - 特許庁After stopping the small pump 10, the hose used for pumping river water is removed from the water intake 10a of the small pump 10, and one side of the discharge hose 11 connected to the first connection 3 of the portable bathtub 1 is removed. 11 a is connected to the discharge port 10 b of the small pump 10 . As described above, the preliminary preparation for heating the water stored in the portable bathtub 1 to a bathing temperature is completed.

Next, the small pump 10 is driven by power supply from the battery 12, and the water stored in the portable bathtub 1 is taken from the water intake portion 10a of the small pump 10 as indicated by the arrow P. It is discharged from the discharge port 10b to the discharge hose 11 as indicated by the arrow Q, and supplied to the first pipe 8 as indicated by the arrow A through the first connecting portion 3. As shown in FIG.

The water supplied to the first pipe 8 passes through the third connecting portion 6 and flows from the inlet portion 5 a of the heating tube body 5 to the helically wound portion 5 c of the heating tube body 5 . A fire as a heating source 13 is installed below the spirally wound portion 5c of the heating tube body 5, and the spirally wound portion 5c of the heating tube body 5 is heated by flames of the fire as the heating source 13. . Therefore, the water flowing through the spirally wound portion 5c of the heating tube body 5 is heated and flows from the outflow port portion 5b of the heating tube body 5 through the fourth connection portion 7 to the second pipe 9 as indicated by an arrow B. , and the heated water is circulated into the portable bathtub 1 through the second pipe 9 and the second connecting portion 4 .

By repeating such a circulation operation, when the heated water in the portable bathtub 1 reaches a bathing temperature, for example, 43 degrees, the power supply from the battery 12 is stopped and the small pump 10 is stopped.

As described above, since the portable bathtub 1 is ready for bathing, even if one gets sweaty or dirty during outdoor activities or camping, the user can take a bath in the portable bathtub 1 at a water temperature of, for example, 43°C. You can enter the bath and maintain the habit of taking a bath every day, so you can enjoy comfortable outdoor activities or camping without accumulating stress.

Also, when the temperature inside the portable bathtub 1 drops, the small pump 10 is driven by power supply from the battery 12 again, and the above-described circulation operation is repeated to raise the temperature inside the portable bathtub 1. .

By the way, when dismantling the portable bath apparatus, the other side 11b of the discharge hose 11 and the one side 8a of the first pipe 8 are removed at the first connecting portion 3 of the portable bathtub 1 from which the water is drained. At the second connecting portion 4 of the portable bathtub 1, the other side 9b of the second pipe 9 is removed.

At the third connecting portion 6, the other side 8b of the first pipe 8 is removed. At the fourth connecting portion 7, one side 9a of the second pipe 9 is removed. Then, the small pump 10 is taken out. Each part is dismantled in this way.

Since the portable bathtub 1 is made of vinyl, it is folded to be compact, and since the first pipe 8 and the second pipe 9 are composed of flexible pipes, they are wound to be compact. These parts may be packed in a dedicated storage case and placed on the car, or they may be placed on the car as they are.
