A second housing member 30 formed of a metal material in the shape of a hollow cylinder is coupled to the other side of the first housing member 10 on the side where the first heating member 20 is disposed.

The diameter of the second housing member 30 is formed in a cylindrical shape smaller than the diameter of the first housing member 10, the portion where the first housing member 10 and the second housing member 30 are coupled A jaw is formed in the.

It is preferable that the first housing member 10 and the second housing member 30 are made of stainless steel.

In addition, a second heating member 40 that generates heat by the supplied power energy is disposed inside the second housing member 30.

As shown in FIG. 6, while the second heating member 40 is space-efficiently disposed inside the second housing member 30, the maximum amount of water is generated in the process of flowing the inside of the second housing member 30. The second heating member 40 is disposed in the second housing member 30 along its longitudinal direction so that heat transfer can be achieved.

In addition, the second heating member 40 includes a first hollow pipe 44 formed by bending in a "U" shape and a second hollow pipe 46 formed by bending in a "U" shape, the first The hollow pipe 44 and the second hollow pipe 46 are disposed in a direction perpendicular to each other in a plane perpendicular to the longitudinal direction thereof.

Since the second heating member 40 heats the water flowing while occupying a large area with respect to the cross-sectional area inside the second housing member 30 formed with a narrower diameter than the first housing member 10, water It has a more favorable effect on precise control of temperature.

That is, while the water stored in the first housing member 10 is primarily heated, water flowing through the narrow second housing member 30 is additionally heated through the second heating member 40 By discharging, it is possible to rapidly increase the temperature of the water finally discharged, and since the amount of water to be controlled by heating is heated in a small state, the accuracy of control may be improved.

The outlet 60 is installed in a direction perpendicular to the second housing member 30.

At the end of the second heating member 40, a connector plug 42 for closing the side end of the second housing member 30 is disposed. As shown in FIG. 11, the connector plug 42 A connection terminal is installed to receive external power.

The water flowing inside the second housing member 30 is mixed with water that bounces off the connector plug 42 and is discharged through the water outlet 60.

Thus, by allowing the water flowing inside the second housing member 30 to be discharged to the outlet 60 in a state in which the water flowing inside the second housing member 30 is actively mixed, the temperature of the discharged water can be made more uniform.

A temperature sensor 72 is installed in the vicinity of the water outlet 60, and the temperature measured by the temperature sensor 72 is transmitted to a controller (not shown).

As a result, irregular turbulence is formed in the water flowing inside the second housing member 30 so that the water can be mixed at a uniform temperature.

As another embodiment for generating turbulence in the water flowing inside the second housing member 30, as shown in Figs. 10 and 11, a spiral concave portion 34 on the inner surface of the second housing member 30 Can be formed.

The helical concave portions 34 serve as a flow obstacle, such as a jaw, with respect to water flowing inside the second housing member 30, thereby flowing inside the second housing member 30. Water may irregularly contact the second heating member 40 in a turbulent state.

Thus, the heat transfer efficiency for water flowing inside the second housing member 30 is remarkably increased, and uniform heating is possible.

In another embodiment of the present invention shown in FIG. 12, the spiral concave portion 14 is formed of a first spiral concave portion 34 and a second spiral concave portion 36 formed at different angles of inclination. Can be.

The second housing member 30 is formed by bending a long rectangular stainless steel plate having a predetermined thickness and a narrow width in an arc cross section as shown in FIG. 9, and then two semicircular cross-sections of the second housing members 30-1 and 30-2. ) May be welded to form one second housing member 30.

Therefore, after sandblasting the surface of the stainless steel sheet, they are bent into an arc cross-sectional shape to form the divided second housing members 30-1 and 30-2 as shown in FIG. 9, and then welded to form the second housing members 30-1 and 30-2. The second housing member 30 may be completed.

Or, in a state where the stainless steel sheet is bent in an arc cross-sectional shape, as shown in Figs. 10 to 12, spiral concave portions are formed on the inner surfaces of the second housing members 30-1 and 30-2 using a processing device. In addition, the second housing member 30 may be completed by welding the two second housing members 30-1 and 30-2.

As shown in Fig. 13, the inner diameter of the second housing member 30 is the progress of water so that the water flowing inside the second housing member 30 can be discharged with a strong pressure through the outlet 60. It may be formed to gradually decrease along the direction.

Thus, the space s2 between the lower end of the second heating member 40 and the inner surface of the second housing member 30 is the second heating member 40 on the side of the outlet 60 (the upper end of the second heating member). It is formed larger than the space (s1) between the inner surface of the second housing member (30).

Thereby, the more water is directed toward the outlet 60, the stronger the pressure is to contact the second heating member 40 to receive heat, and the water can be discharged and flowed at a strong pressure through the outlet 60. .

In addition, as it faces toward the outlet 60, heat is received more strongly, and it becomes more advantageous to finally increase the discharge temperature to a predetermined discharge temperature.
