To be formed.

In addition, the second drum 120 is fixed to the first rotation shaft member 20 so as to be located inside the first drum 110 and is open to both sides. At this time, since the second drum 120 is open to both sides, the second drum 120 and the first rotating shaft member 20 are connected to the middle rib 124. Thus, the second drum 120 rotates stably around the first rotating shaft member 20.

In addition, the reason why the second drum 120 is opened to both sides is to sufficiently circulate the heat medium generating frictional heat by a part of the second frictional heat generating unit 200 inserted into the second drum 120. Of course, the second drum 120, like the first drum 110, may seal one side.

In addition, although the first drum 110 and the second drum 120 may be positioned so as not to overlap each other, the second drum 120 is provided inside the first drum 110 to reduce the volume of the case 10. It is preferable to.

At this time, since the third drum 130 is open to both sides, the third drum 130 and the first rotating shaft member 20 are connected to the lower rib 134. Thus, the third drum 130 rotates stably around the first rotating shaft member 20.

In addition, the reason why the third drum 130 is opened to both sides is to sufficiently circulate the heat medium generating frictional heat by a part of the second frictional heat generating unit 200 inserted into the third drum 130. Of course, like the first drum 110, the third drum 130 may seal one side.

In addition, although the second drum 120 and the third drum 130 may be positioned so as not to overlap each other, the third drum 130 is provided inside the second drum 120 to reduce the volume of the case 10. It is preferable to.

That is, since each of the first discharge hole 112, the second discharge hole 122, and the third discharge hole 132 forms a curved portion 140 having a substantially 'S' shape in cross section, the heat medium discharged is curved surface portion. While hitting the inner side of 140, it generates more frictional heat. Of course, the curved portion 140 may be formed in various shapes. In addition, each of the first discharge hole 112, the second discharge hole 122, and the third discharge hole 132 may be modified in various shapes on a plane.

Here, the first drum 110, the second drum 120 and the third drum 130 are formed in a cylindrical shape to serve to limit the fluidity of the heat medium having fluidity. Thus, the first wing 210, the second wing 220 and the third wing 230 of the second frictional heat generating unit 200, which will be described later, respectively, the first drum 110 and the second drum 120 and Located inside the third drum 130 while rotating to serve to maximize the generation of frictional heat in the heat medium is limited fluidity.

In addition, the second wing 220 is fixed to the second rotating shaft member 30 and is formed between the second drum 120 and the third drum 130 to maximize the generation of friction heat of the heating medium during rotation. In addition, the third wing 230 is fixed to the second rotation shaft member 30, is formed inside the third drum 130 to maximize the generation of friction heat of the heating medium during rotation.

In this case, the third wing 230 is located inside the second wing 220, and the second wing 220 is located inside the first wing 210. This is to reduce the volume of the case 10 by mounting the first wing 210, the second wing 220 and the third wing 230 overlapping. In particular, the first wing 210, the second wing 220 and the third wing 230 are arranged in order in one direction from the other side of the case 10.

Meanwhile, each of the first wing 210, the second wing 220, and the third wing 230 includes a frame 242, a connecting rod 244, and a knob 246.

The frame 242 is formed in a ring shape of a circular or polygonal, the connecting table 244 serves to connect the frame 242 and the second rotary shaft member 30. In particular, the connecting table 244 is preferably molded or injection molded integrally with the frame 242, it may be formed in a variety of shapes. In addition, the connecting table 244 serves to enable the frame 242 to rotate stably around the second rotary shaft member 30. In addition, the connecting table 244 may be integrally formed or detachably assembled to the second rotation shaft member 30.

In addition, the knob 246 is extended from the frame 242 is rotated and serves to generate the maximum vortex in the heating medium. Thus, a plurality of knobs 246 are preferably formed along the edge of the frame 242. In this case, as illustrated, a plurality of knobs 246 may be extended to both sides of the frame 242, and although not shown, the first drum 110, the second drum 120, and the third drum, respectively, are not shown. It may be formed to extend in one direction of the casing 10 to be rotated inside the drum (130). The knob 246 can be modified into various shapes. And, the knob 246 is preferably formed as thick as possible within the range to increase the contact area with the fluid heat medium. Although not shown, each of the knobs 246 may be broken by side pressure generated by the heat medium, so that a part of the heat medium may pass through the hole.

Accordingly, the frame 242, the connecting rod 244, and the knob 246 of the third wing 230 are positioned inside the third drum 130 to restrict fluidity inside the third drum 130, thereby limiting the third drum ( The generation of frictional heat is maximized by generating another vortex in the direction of the third wing 230 in the heating medium that generates the vortex in the rotational direction of 130. The heat medium is discharged between the third drum 130 and the second drum 120 through the third discharge hole 132 of the third drum 130.

In addition, the frame 242, the connecting rod 244, and the knob 246 of the second wing 220 are positioned between the third drum 130 and the second drum 120 to provide fluidity inside the second drum 120. This is limited to maximize the generation of frictional heat by generating the vortex in the other direction to the heating medium that generates the vortex in one direction.

The fluid is heat-exchanged and heated by frictional heat generated while flowing into the inner member 14 during the fluid flow through the inlet 15. This heated fluid is discharged through the discharge port 16 and used as hot water.

In addition, the space part 12 forms a communication hole 13 so as to communicate with the inside of the case 10. Thus, the heated heating medium is introduced into the space 12 through the communication hole 13 and then comes into contact with the inner member 14 during the fluid oil. Here, the fluid member inner member 14 is preferably made of a tube of a flexible material to be wound inside the circumferential surface of the case (10).

In addition, the connection portion between each of the inlet 15 and the outlet 16 of the inner member 14 and the case 10 during the fluid oil is preferably sealed to prevent the occurrence of gaps.
