Abstract

The present invention relates to an instantaneous water heater. Water flowing into a lower water inlet (100c) is discharged to an upper opening (42) while being continuously heated with a heating rod (10) by passing through a first tubular heating body (100) and an upper gap (T1), and through a second tubular heating body (200), a lower gap (T2), and a hollow rod (40), that is, through the lower side, the upper side, the lower side, and then the upper side. As a result, the heating with the heating rod (10) can be performed doubly and triply and thus electric energy waste can be significantly reduced by means of maximum thermal efficiency. In addition, the water flowing in the lower water inlet (100c) hits and stays in a heating fin (400) in the second tubular heating body (200) surrounding the hollow rod (40), and exchanges heat with the heating rod (10) from the hollow rod (40). The contract surface area of the water is maximized, and the temperature keeping function thereof is significantly enhanced along with the time of water heating with respect to heating. In that state, the water can be discharged to a hollow hole (43) and the upper opening (42) so that heat efficiency can be maximized and electric energy waste can be significantly reduced.

FIG. 7A is an exploded perspective view showing the hollow rod 40 and the heating rod 10 applied to the instantaneous water heater according to the present invention, FIG. 7B is an exploded perspective view showing the hollow rod 40 and the heating rod 10 applied to the instantaneous water heater according to the present invention, Fig.

According to the present invention, the upper joining means K is provided with a boundary jaw 44 having a larger diameter than the hollow hole 43 of the hollow rod 40, as shown in Figs. 7A and 7B, An O-ring 22 which is inserted into the receiving hole 45 and is brought into contact with the boundary jaw 44 while being fitted into the heating rod 10; and a screw shaft 46 formed on the outer circumferential edge of the end of the hollow rod 40, A pushing ring 23 which is fitted into the heating rod 10 and enters into the receiving hole 45 to abut on the O-ring 22 and a screw groove 24b to be engaged with the thread 46, Is screwed into the hollow rod 40 so as to tightly seal the outer periphery of the heating rod 10 and the inner periphery of the receiving hole 45 while enlarging the outer periphery of the O- And a rotating body (24) coupled thereto.

As the rotating body 24 is screwed into the hollow rod 40, the pushing ring 23 presses the O-ring 22 toward the boundary step 44, and as the O-ring 22 is pressed, it is contracted in the entering direction So that leakage between the outer periphery of the heating rod 10 and the inner periphery of the receiving hole 45 is more tightly sealed and sealed, thereby thoroughly eliminating leakage.

The rotating body 24 has a cylindrical body 24a having a thread groove 24b and a cylindrical body 24a which receives the heating rod 10 while being vertically reduced from the cylindrical body 24a, And a pushing jaw 24c for advancing the pivot 23.

The simple structure of the cylindrical body 24a engaged with the thread 46 of the hollow rod 40 allows the pushing ring 23 to be easily advanced to the pushing jaw 24c while protecting the heating rod 10, To ensure the sealing function.

The heating rod 10 applied to the instant water heater according to the present invention includes a woven carbon fiber yarn 11 for converting electric energy into thermal energy and a heat resistant glass tube 12 having a carbon fiber yarn 11 And a first connection terminal 13a and a second connection terminal 13b (for example, molybdenum having a very small degree of thermal deformation) connected to one end and the other end of the carbon fiber yarn 11, The first lead wire 14a and the second lead wire 14b connected to the outside and exposed to the outside and the first connection terminal 13a and the second connection terminal 13b at the end of the heat resistant glass tube 12, And a press contact portion 12a.

When the electrical energy is supplied through the first lead wire 14a and the second lead wire 14b, the carbon fiber yarn 11 in the heat-resistant glass tube 12 (the heat-resistant glass tube 12 filled with the inert gas) So that the hollow rod 40 can heat the water.

The heating rod 10 has a connection line 16a connected to one end of the carbon fiber yarn 11 while being connected to the first connection terminal 13a and a connection line 16b connected to the second connection terminal 13b, And a center line 16b that is inserted into the erected section 17 and connected to the other end of the carbon fiber yarn 11. [

One end and the other end of the carbon fiber yarn 11 are respectively connected to the center line 16b sandwiched between the connection line 16a and the insulation 17 so that the first connection terminal 13a and the second connection terminal 13b are heat- The first power cable 31a and the second power cable 31b can be easily connected to each other and a simple structure can be realized.

At this time, the heating rod 10 is fixed to the center line 16b connected to the other end of the carbon fiber yarn 11 and then spread in both directions to be elastically supported on the inner circumference of the heat resistant glass tube 12, And a tension support 19 for preventing the glass tube 12 from flowing simultaneously with centering.

The center line 16b can be centered without being eccentric in the heat resistant glass tube 12 by the tension supporting portion 19 elastically supported on the heat resistant glass tube 12, It is possible to minimize damage to the carbon fiber yarn 11 due to contact when the carbon fiber yarn 11 is heated due to the direct contact with the inner periphery of the carbon fiber yarn 11. In addition, the center line 16b can be moved up and down, Even if the carbon fiber yarn 11 is subjected to the operation while the heat-resistant glass tube 12 is standing up when the crimping portion 12a is provided with the first connection terminal 13a and the second connection terminal 13b as the center, The heat of the heat-resistant glass tube 12 can be prevented from being lowered by the weight of the heat insulating tube 17, the center line 16b, and the like, so that the productivity of the pressing part 12a can be improved.

More specifically, the tension supporting portion 19 includes a winding portion 19a wound around the center line 16b, a wire 19b bent downwardly in the diagonal direction from the lower end of the winding portion 19a, 19a of the heat resistant glass tube 12 and bent downward from the upper end of the heat resistant glass tube 12 so as to be folded downward and supported by the heat resistant glass tube 12 with one wire 19b and the other wire 19c centered on the center line 16b, And the other wire 19c and the other wire 19c when the carbon fiber yarn 11, the insulation 17 and the center line 16b are inserted into the heat resistant glass tube 12, While the carbon fiber yarn 11, the insulation 17 and the center line 16b are elastically supported by the elastic supporting force of the tension supporting portion 19 during the applying operation of the pressing portion 12a, ) Is prevented completely.

The present invention can be used in the field of electric heaters which convert electric energy into heat energy to warm the surroundings.
