1 is an assembled perspective view of a heating element heater of the instant electric hot water boiler according to an embodiment of the present invention. Referring to FIG. 1, the inner tube 120 is interpolated and assembled into an outer surface 100 of an empty glass material. Of course, for this purpose, the left side of the exterior 100 is closed and molded integrally, and the right end is open. Therefore, a hollow is formed in the exterior 100.

The inner tube 120 is inserted into the hollow of the exterior 100. The inner tube 120 has a shape in which both ends are open, unlike the exterior 100. Of course, the inner tube 120 also uses a glass material. Glass materials include, but are not limited to, soda lime glass, borosilicate glass, acrylic resin, sugar glass, mica or aluminum oxynitride.

In particular, in one embodiment of the present invention, quartz glass containing almost no silicic acid anhydride is used. This quartz glass is widely used in chemical instruments and the like because of its rich mechanical strength and chemical resistance.

The first coupling part 121 closing the left end is assembled and fastened to the inner tube 120, and the second coupling part 122 fixed and supported on the surface of the inner pipe 120 is assembled and fastened at a right distance to the right end. do. Of course, the first coupling portion 121 and the second coupling portion 122 are metallic and have an electrically conductive property.

The first coupling portion 121 is assembled and fastened to the left end of the inner tube 120 in an integral shape in which the left end is closed, and is joined to the left end of the heat transfer resistor 130 surrounding the surface of the inner tube 120. This joint is made by electrical welding or the like.

The heat transfer resistor 130 is fixed to surround the surface of the inner tube 120 in a spiral shape, and when electricity passes through the heat transfer resistor 130, the heat transfer resistor 130 emits heat and light. Heat transfer resistor 130 according to an embodiment of the present invention uses a heat transfer resistor of Patent No. 10-0898777 (Inventive name: heat transfer resistor and its manufacturing method) registered by the applicant.

A diagram showing the structure of this heat resistant resistor 130 is shown in a partial cross-sectional enlarged view at the upper right. Referring to the enlarged cross-sectional view, the heat transfer resistor 130 is formed on the surface of the electrically conductive fiber yarn 131 as a carrier, the metal compound including a metal component having a wavelength band similar to the inherent wavelength band of the target object to be infiltrated and formed The coating layer 132 is included.

Therefore, a heat generation wavelength based on a metal component of the coating layer 132 is generated along with heat generation energy when heat is generated by applying electricity to the electrically conductive fiber yarn 131, and the heat transfer wavelength is similar to the inherent wavelength band of the heated object.

By this principle, since the movement of the molecules inside the heated object is further amplified and activated, rapid heating is achieved and energy saving is achieved. As it is described in more detail in Patent No. 10-0898777 No further description will be omitted.

Referring to FIG. 1, when the heat resistance resistor 130 is fixedly coupled to the surface of the inner tube 120, the second coupling part 122 for fixing the right end of the heat resistance resistor 130 may have an appearance 100. It is assembled to the surface of the exterior 100 to be spaced apart by a predetermined distance to the end of the.

Of course, at one end of the second coupling portion 122, a protrusion 123 having a space for joining the end of the heat transfer resistor 130 is formed.

When the second coupling part 122 is assembled to the inner tube 120 and the heat resistance resistor 130 is bonded, the first electrode wire 141 is inserted into the hollow formed in the inner tube 120 to be bonded to the first coupling part 121. The first electrode portion 140 in which is formed is inserted.

The first electrode line 141 formed on the first electrode part 140 is formed at the right end of the inner tube 120 to form a bent part 142 spaced apart from the inner tube 120 and the second electrode line 151 at a predetermined interval. do. The bent portion 142 is formed to be bent outward.

Therefore, the first electrode line 141 formed in the first electrode part 140 is inserted only up to the bent part 142 due to the bent part 142.

On the other hand, the second electrode line 151 formed in the second electrode unit 150 at a predetermined interval from the first electrode unit 140 is inserted into the hollow formed in the outer appearance (100). Of course, the second electrode wire 151 is bonded at the protrusion 123 assembled at a specific position of the inner tube 120. Of course, this joining can be made by electric welding or the like.

Accordingly, the second electrode line 151 maintains a constant distance from the surface of the inner tube 120 and also maintains a constant distance from the front end of the bent portion 142 of the first electrode line 141. Of course, a constant distance is maintained between the first electrode unit 140 and the second electrode unit 150.

The first wire 160-1 and the second wire 160-2 are connected to the first electrode part 140 and the second electrode part 150, respectively. In addition, of course, these 1st electric wire 160-1 and the 2nd electric wire 160-2 are covered by the 1st electrode coating 160 and the 2nd electrode coating 161, respectively, and the 1st electric wire 160-1 ) And the second wire 160-2 are insulated from the outside.

Of course, as the material of the coatings 160 and 161, an inorganic solid insulating material, an organic fibrous material, a resin material, a rubber material, a paint material, and the like are used. However, in one embodiment of the present invention, an inorganic solid insulating material is suitable when the instant electric hot water boiler having the appearance 100 is used in a high temperature situation. In general, inorganic solid insulation materials are used, such as mica, asbestos, magnetism, etc., so they have insulation and fire-proof.

Figure 2 is an external perspective view of the heater heater of the instant electric hot water boiler according to an embodiment of the present invention. That is, referring to FIG. 2, the inner tube 120, the heat resistant resistor 130, the first electrode part 140, the second electrode part 150, and the like are assembled and fastened in the exterior 100 to the end of the exterior 100. It shows the shape of the pressed seal. In particular, the left end of the heat resistance resistor 130 is bonded at the first junction 200 of the first coupling portion 121, and the right end of the heat resistance resistor 130 is the second junction point of the second coupling portion 122 ( At 210).

In addition, as shown in Figure 2, the right end of the outer surface 100 by pressing the first electrode portion 140 and the second electrode portion 150 by pressing a certain interval, so that the compression seal 230 is formed The state in the appearance 100 is maintained in a vacuum state.

Therefore, since no foreign matter or water is injected into the exterior 100, it is possible to safely use the instant electric hot water boiler according to the present invention.

In addition, there may be a process of injecting gaseous gas into the exterior 100 before the compression sealing. As the injection gas, the most stable (no chemical) inert gas is used (helium, neon, argon, xenon, etc.) on the far right of the periodic table. Nitrogen (N ₂ ) may be used as well as such inert gas.

These inert gases act to maintain the exothermic state of the heat transfer resistor 130. In other words, tungsten is used as a filament like an incandescent bulb, and when tungsten is combined with air, the incandescent state is not maintained.

When power (particularly, AC power is used) is applied to the first electrode part 140 and the second electrode part 150 due to the gas injected into the exterior 100, the heat generating element 130 emits light with heat. Will also happen. Therefore, the thermal efficiency is very high due to the generation of electromagnetic waves together with the heat generated by the electrothermal heating element 130. That is, the electromagnetic wave is reflected on the pipe wall (not shown) during the occurrence of electromagnetic waves (particularly, infrared rays), so that radiant heat is generated to generate heat, thereby effectively heating cold water.

In FIG. 2, the right end of the exterior 100 is press-sealed, but alternatively, a cover means such as a rubber packing stopper may be used.

3 is an assembled perspective view of the instant electric hot water boiler according to an embodiment of the present invention. Referring to FIG. 3, in the instantaneous electric hot water boiler 300, a pipe 340 is arranged like a “U” magnetic pipe, cold water is supplied from the inlet 310, and the supplied cold water flows through the pipe 340. Will be. Of course, the insertion part 320 is formed at one end of the pipe 340.

The fixing part 350 is assembled into the inserting part 320 by a screw method. The fixing part 350 is smaller than the diameter of the inserting part 320 to be inserted into the inserting part 320, and a screw groove is formed. The heating element heater 390 is inserted through the fixing part 350.

When the heater heater 390 is inserted, the rubber packing 360 is inserted to prevent water from leaking from the inserting part 320. Of course, in order to ensure that the rubber packing 360 is securely supported by the fixing part 350, the stopper 370 is assembled by screwing. An opening (not shown) is provided at the center of the plug portion 370 so that the power line is connected to the heating element heater 390.

In addition, in FIG. 3, the heater heater 390 is similarly inserted into other inserts in such a manner that the heater heater 390 is inserted into the inserter 320.

In other words, the heater elements 390 are installed to intersect, that is, at regular intervals. Therefore, since the pressure is applied to the pipe side of the pipe 340 in which the heating element heater 390 is inserted, and the pressure is not applied to the pipe side of the pipe 340 in which the heating element heater 390 is not inserted, the pipe 340. The pressure at the top of the pipe side does not increase.

4 is a cross-sectional view of a portion of the instant electric hot water boiler in FIG. 3 taken along the line X-X '. Since the heating element heater 390 (FIG. 3) is positioned between the pipes 340, the cold water flows through the space between the inner wall of the pipe 340 and the appearance 100 of the heating element heater 390. That is, the cold water is heated by the heat radiated to the inner wall of the pipe 340 by the heat and light emitted from the heat transfer resistor 130 of the heat heater 390 while the cold water flows in the direction of the water flow arrow 400.

5 is a view showing the instant electric hot water boiler according to another embodiment of the present invention. 5, The outer casing 510 is provided with a reservoir 520 therein, and an inlet pipe 521 through which cold water flows and an outlet pipe 523 through which hot water flows out are connected to both lower sides of the reservoir 520. At this time, the outflow pipe 523 occupies a position where the end thereof is higher than the inflow pipe 521.

In addition, connecting pipes 525 are connected to ends of the inflow pipe 521 and the outflow pipe 523, respectively. Accordingly, the inflow and outflow of the cold water and the hot water flow out through the connection pipe 525.

Inside the reservoir 520 is a heating element heater 390 according to the present invention for heating the water introduced into the reservoir 520 by generating heat when power is applied. Accordingly, the cold water introduced through the inlet pipe 521 is heated by the heating element heater 390 is converted into hot water, such hot water flows over the reservoir 520 by the convection of heat to the outlet pipe 523.
