Next, the lock member 40 is pulled out from the pushing portion 34 of the pushing member 32.
Then, the pressing portion 33 of the pressing member 32 is pressed downward.

When the pressing part 33 is pushed downward, the pushing part 34 moves downward, the tip part moves the partition part 17 downward, and the purified water 18 accommodated in the upper part of the partition part It flows down from the surroundings.
The purified water 18 flowing down causes a chemical reaction with the quicklime 19 accommodated in the lower portion of the heating unit 15 to generate heat.

Thereby, the temperature inside the heating unit 15 rises rapidly, the internal pressure inside the heating unit 15 rises rapidly, and the mineral water in the plastic bottle B flows from the suction tube 13 to the heating tube 14.
The mineral water 18 that has flowed into the heating tube 14 is heated inside the heating tube 14 that is formed in a spiral shape.

Finally, the hot water or hot water that has reached the hot water supply section 16 can rotate the cock section 26 of the open / close cock section 24 to discharge the hot water or hot water from the discharge port 25t.
At this time, the cap part 27 is opened in advance.
As will be described later, the cock portion 26 can change the temperature of the water to be discharged depending on the rotation angle and can cause the water to flow out.

  FIG. 2 is a partially cutaway central longitudinal cross-sectional view of the water heater according to the above embodiment, illustrating a state in which the pushing member is pushed downward and water and quicklime are reacted, and the outlet of the opening / closing cock portion is illustrated. The state which removed the cap part is illustrated. FIG. 2 is slightly larger than FIG.

  As well understood from this figure, the locking member (not shown) is removed and the pushing member 32 is pushed downward, so that the tip of the pushing portion 34 moves the partitioning portion 17 downward. The purified water 18 accommodated inside flows downward from the outer periphery of the partitioning part 17 and causes a chemical reaction with the quicklime 19 accommodated in the lower part of the heating part 15. Heat can be generated.

When the temperature inside the heating unit 15 rises, the internal pressure rises, the air and water vapor in the heating unit 15 pass through the pipe 30 and flow into the plastic bottle B, the pressure inside the bottle rises, and the minerals inside Water flows into the heating tube 14.
The mineral water is heated and heated while flowing through the long heating tube 14 wound spirally.

  Here, the relationship between the partitioning part 17 and the heating part 15 will be described in detail again. In the state shown in FIG. 1, the partitioning part 17 is tightly fixed to the inner wall surface of the heating part 17, and purified water contained in the upper part thereof. Reference numeral 18 denotes a structure that does not flow downward.

  And when the partition part 17 is pushed down to the state of FIG. 2, the inner diameter of the inner wall surface of the heating part 15 is formed larger than the inner diameter of the upper part, and therefore the partition part 17 moves downward. A gap is formed between the outer periphery of the partitioning part 17 and the inner wall surface of the heating part 15, and the purified water 18 accommodated in the upper part can flow down.

It should be noted that a plurality of protrusions may be provided in parallel in the longitudinal direction of the inner wall surface of the portion having a large inner diameter (large diameter portion) of the heating unit 15.
Thereby, the purified water 18 accommodated in the upper part can be gradually flowed down.

Here, the pressure regulating valve 22 will be described.
The pressure adjustment valve 22 is provided in the middle of the internal flow passage of the hot water supply unit 16, and when the internal pressure of the heating pipe 14 reaches a predetermined pressure, in this embodiment, 3 atmospheres, the pressure adjustment valve 22. Is moved to the right, and the internal flow passage on the heating tube side of the heating tube 14 and the hot water supply unit 16 is opened.

That is, the pressure regulating valve 22 employs a structure in which the internal flow passage of the hot water supply unit 16 is always urged leftward in the drawing by a coil spring to seal the internal flow passage. When a pressure equal to or higher than a predetermined pressure is applied to the valve 22, the valve moves to the right in the figure, and the internal flow passage is opened.
By comprising in this way, supply of the warm water from the heating pipe 14 is stopped temporarily, the pressure regulating valve 22 is opened when it becomes more than a predetermined pressure, and warm water above a predetermined temperature is discharged. Is made possible.

  Moreover, in this embodiment, the downward extension part 29 which extended further the lower end part of the cylindrical wall surface part 15w of the heating part 15 of the simple water heater 10 which concerns on this invention further downward is provided, and this downward extension part 29 is provided. It forms so that it may contact | abut to the upper shoulder part S of the plastic bottle B, Thereby, the external appearance of the simple water heater 10 which concerns on this invention is made smarter, The presence of this downward extension part 29 makes this simple hot water supply. The container 10 is attached to the plastic bottle B more stably and more firmly.

FIG. 3 is a plan view of FIG.
As is well understood from this figure, the pressing portion 33 of the pushing member 32 has a substantially circular shape in plan view, and similarly, the heating portion 15 also has a substantially circular shape in plan view.
Further, the planar shape of the open / close cock part 24 provided in the hot water supply part 16 can also be seen well, and a temperature display is provided on the upper end surface of the cylindrical body part 25 of the open / close cock part 24, and the cock part The temperature of the hot water discharged by rotating 26 greatly decreases.

That is, the discharge temperature of the hot water is lowered by increasing the flow rate.
