Description

Electric heater {Electric heater}

The present invention relates to an electric heater, and more particularly to an electric heater of the fan type using a halogen.

As the standard of living improves, the hearth of the indoor heating system has also escaped from the past by oil, and electric heaters, especially electric heaters in the form of fans have recently become commonplace. As social demand gradually increases, various types of electric heaters are being developed.

As is well known, the electric heater of the fan type is a basic operation principle to supply electric current to the heating wire in a certain space protected by the safety net, and heat the surrounding air as the heat generated therein. In addition, the electric heater is provided with accessories and other related devices for more efficiently dissipating heat from the heating wire. As a representative example of such an accessory device, although an electric heater in which a reflector plate formed by bending a rectangular metal sheet is usually installed at the rear of a heating wire is widely used, it is not very effective.

1 shows a conventional fan type heater device. 2 is an enlarged perspective view of a heater mounted on a heater device.

As shown in Figure 1 and 2, there is provided a main body in the form of a fan comprising a base 1, a post 2 and a heater unit (3). The heater part 3 comprises a heater core 10 arranged between the parabolic reflector 4 and the guard net 5. The heater core 10 is composed of a ceramic cone body 10 of a conical ceramic material and a circular halogen heater 8 wound around the cone body 10.

The ceramic cone body 10 includes a flange portion 14 extending along the front circumference. At the circumference of the ceramic cone body 10, protrusions 17 protruding to the outside are formed. The halogen heater 8 is disposed close to the flange 14 and fastened to the fastening band 19.

The terminal portion 12 protruding outward from the halogen heater 8 extends over the protrusion 17 of the ceramic cone body 10. The protruding portion 17 is formed with a recessed portion 18 in which the terminal portion 12 is accommodated, so that the terminal portion 12 of the halogen heater 8 is spaced apart from the ceramic cone body 10. In addition, a plurality of through holes 15 are formed in the circumference of the ceramic cone body 10, and heat radiated from the halogen heater 8 through the through holes 15 directly radiates to the front of the ceramic cone body 10. do.

One end of the heating wire is connected to the terminal part 12, and the other end enters the inside of the ceramic cone body 10 to be connected to the fan type main body. On the other hand, as shown in detail in FIG. 2, the ceramic cone body 10 has its short diameter fixed to the fan-shaped body by two bolts and nuts. Therefore, two holes and two bolt fastening holes are formed in the short diameter portion of the ceramic cone body 10 fixed to the fan-shaped body.

However, the electric heater according to the prior art has the following disadvantages. First of all, in addition to the main function of radiating heat, the ceramic cone must have the additional function of protecting the heating wire passing therethrough from heat. Therefore, in order for the radiation function and the protection function to be effectively exhibited, it is relatively advantageous that the surface area of the ceramic cone body is large. However, since the conventional ceramic cone has a shape that gradually decreases in diameter as it moves toward the fan-shaped main body side, many pointed out that the ceramic cone body does not have a surface area that can effectively exhibit the radiation function and the protection function. In particular, since the heat inside the ceramic cone is not quickly released to the outside, the heating wire melts or burns, and thus the risk of disconnection and exposure is frequently generated. Such disconnection and exposure have been the main causes of failure of electric fan-type electric heaters. Until now, no countermeasures have been proposed.

In addition, the conventional electric heater has a problem that the heating wire portion disposed from the terminal portion of the halogen heater to the ceramic cone body is too long, that is, there are too many heating wire portions exposed to the outside. Although, as shown in FIG. 2, the protection tube made of ceramic material is coated on the heating wire portion exposed to the outside of the ceramic cone body, the heating wire in the protection tube melts or burns due to the high temperature heat radiated directly from the halogen heater. The risks of disconnection and exposure as indicated could not be prevented.

In addition, although the weight of a ceramic cone body is quite heavy, conventionally, only the short diameter part of a ceramic main body is supported by the fan type main body. As a result, a phenomenon in which the long diameter portion of the ceramic cone body is slightly sag occurs, and even when the bolt is loosened, the ceramic cone body falls and there is a serious problem that an expensive halogen heater is broken.

The present invention was devised to solve all the problems of the conventional electric heater described above, and by changing the shape of the cone, the surface area of the cone is greatly expanded than before, further improving the radiation function, which is an original main function, and especially the inside of the cone. An object of the present invention is to provide an electric heater that can prevent the heating wire from melting or burning.

Another object of the present invention is to minimize the portion of the heating wire that is exposed to the outside of the cone, to prevent the phenomenon that the exposed portion of the heating wire is melted or burned by the high temperature heat.

Another object of the present invention is to allow the long diameter portion of the cone body to be directly supported by the fan-shaped body, to prevent the fall of the cone body and breakage of the halogen heater.

In order to achieve the above objects, the electric heater according to the present invention includes a heat sink of a ceramic material. An annular halogen heater is disposed around one side of the heat sink and secured with a clip. The heat sink has an accommodating portion in which the terminal of the halogen heater is accommodated. One end of the heating wire is connected to the terminal. A guide groove for receiving and guiding the heating wire is formed toward the center of the heat sink from the receiving portion. A cylindrical mounting portion protrudes from the center of the heat sink, and a trumpet-shaped heat sink is provided in the mounting portion. The guide groove extends to the mounting portion, so that the other end of the heating wire guided by the guide groove extends through the inside of the heat dissipation tube, leading to the fan type main body. In the mounting portion, two support holes are formed at equal intervals. The U-shaped fasteners are inserted into the supporting holes from the other side of the heat sink, and both ends of the fasteners extend through the inside of the heat dissipation tube and are fastened by nuts to the fan-type body.

On the other hand, the heat dissipation tube is preferably a light metal material, more preferably aluminum. In addition, in order to radiate heat that is beneficial to the human body, it is also a preferred method to coat charcoal on the outer surface of the heat dissipation tube.

In the heat sink, it is preferable that a plurality of corrugations are formed on the surface thereof in order to expand the heat radiation area. More preferably, the wavy portion is formed in a cylindrical shape in appearance.

According to the configuration of the present invention described above, since the heat dissipation tube is changed to a fallopian tube shape opposite to the conventional cone shape, the surface area is greatly expanded rather than the cone shape, so that the heat dissipation effect is improved and the disconnection of the heating wire is prevented. In addition, the heating wire outside the heat dissipation tube is accommodated in the guide groove so that only a very short portion is exposed to the outside, so that the heating wire melts or burns due to heat. In addition, since the heat sink is directly fixed to the fan-shaped body with a U-shaped fastener, the heat sink is sag and fall, and the damage of the expensive halogen heater is prevented.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a longitudinal sectional view showing an electric heater according to the present invention, Figure 4 is a longitudinal sectional view showing a manner in which the electric heater according to the present invention is fixed to the fan-shaped body, Figures 5 and 6 are heat sinks that are the main part of the present invention Is a front view and a rear view of, Figure 7 is a view showing in detail the fixing clip which is the main part of the present invention.

First, as shown in FIG. 3, the fan-shaped body 20 has a parabolic reflector 21. The electric heater according to the present invention is mounted on the fan-type main body 20, and radiant heat generated by the electric heater is reflected by the parabolic reflector 21 in front.

The electric heater according to the present invention is a circular heat sink 30 disposed in the front center of the parabolic reflector 21, a halogen heater 40 installed on the right side edge of the heat sink 30, and the halogen heater 40 to supply electricity Heating wire 70 for supplying, one end is fixed to the center of the right side of the heat sink 30, the other end is a fallopian tube-shaped heat pipe 60 is fixed to the fan-shaped body 20, and the heat sink 30 to the fan-shaped body ( Fastener 80 for fastening to 20). The heat sink 30 may be changed to a rectangular or other shape instead of the above-described circular shape. On the other hand, the heating wire 70 is connected to the fan type main body 20 through the inside of the heat dissipation tube (60).

The heat sink 30 is in the form of a disk as shown in Figures 5 and 6, the material thereof is a ceramic that emits far infrared rays, which is beneficial to the human body as in the prior art. In particular, unlike the conventional cone shape, the heat sink 30 does not have an open portion. In addition, as shown in Figures 3 to 5, in order to expand the heat dissipation area, it is preferable that the circumferential corrugated portion 38 of which the diameter gradually increases on the right side of the heat dissipation plate 30 is formed to protrude. A circular mounting portion 32 protrudes from the right center of the heat sink 30, and an edge of the mounting portion 32 has a stepped shape to form an annular fixing portion 33. One end of the heat dissipation tube 60 forms a flange portion 61 bent in the center direction, and the flange portion 61 is adhesively fixed to the fixing portion 33.

3, the halogen heater 40 is arrange | positioned at the right side of the heat sink 30, ie, the surface which faces the fan type main body 20 again. As shown in detail in FIG. 5, the halogen heater 40 is substantially circular, and both ends thereof are provided with terminals 41 for receiving an electric supply. As is well known, the halogen heater 40 has a structure in which tungsten filaments are embedded in the quartz tube from which impurities are removed, and an inert gas such as a halogen gas is enclosed therein. Since the decomposition of tungsten is suppressed by the halogen regeneration cycle, the halogen heater 40 has the advantage that the life of the tungsten filament is long and the thermal efficiency is excellent, and since the filament is not exposed to the outside, there is no fear of corrosion or the like.

The circular halogen heater 40 is disposed along the edge of the heat sink 30, it is fixed to be in close contact with the heat sink 30 with a fixing clip (50). As shown in FIG. 6, the fixing clip 50 is fitted into three fixing grooves 34 formed at equal intervals on the heat sink 30 in this embodiment. The detailed structure of the fixing clip 50 is shown in FIG. As shown in FIG. 7, the fixing clip 50 has a shape in which a plate shape is wound in a circular shape so that a circular halogen heater 40 is accommodated, and both ends of the fixing clip 50 extend in parallel to each other. The fixing part 51 inserted into the 34 is constituted. A locking jaw 52 is formed on the middle outer surface of each fixing portion 51, and each locking jaw 52 is supported by a stepped portion formed on an inner wall of the fixing groove 34 as shown in FIG. 3.

One end of the heating wire 70 is connected to the terminal 41 of the halogen heater 40 and the other end is connected to the fan type body 20 through the inside of the heat dissipation tube 60 as described above. In particular, as shown in FIG. 5, the heat sink 30 is provided with a protruding portion 37 in which two terminals 41 of the halogen heater 40 are accommodated. The two heating wires 70 connected to each terminal 41 accommodated in the accommodation portion 37 are directed to the mounting portion 32 side of the heat sink 30, and the heating wire 70 is disposed between the accommodation portion 37 and the mounting portion 32. Guide groove 31 for guiding is formed. And, the heating wire 70 is disposed in the guide groove 31 is covered with a protective cable 72 for blocking high heat. Therefore, as shown in FIG. 3, the portion of the heating wire 70 exposed to the outside becomes very short as compared with the conventional one, and the phenomenon in which the heating wire 70 exposed to the outside due to high heat melts or burns is suppressed.

The heat dissipation tube 60 which performs two functions of suppressing the propagation of heat to the heating wire 70 and dissipating heat generated from the halogen heater 40 to the outside is in the form of a fallopian tube as described above. That is, the short diameter portion of the heat dissipation tube 60 is fixed to the mounting portion 32 of the heat dissipation plate 30, and the long diameter portion is supported by the fan type main body 20. Therefore, the fallopian tube-shaped heat dissipation tube 60 has a shape that gradually increases in diameter from the heat dissipation plate 30 side opposite to the conventional cone body toward the fan type body 20 side, so that the heat dissipation area is expanded rather than the conventional cone body. Has The heat dissipation tube 60, while the conventional cone was ceramic, in the present invention is changed to metal, in particular aluminum. Therefore, the heat dissipation tube 60 of the present invention has the advantage that the weight is lighter than the conventional ceramic cone body, and also has the advantage that the heat dissipation performance is improved. In addition, it is well known that charcoal is beneficial to the human body, it is also a preferred method to coat the charcoal on the outer surface of the heat dissipation tube (60).

Referring to Figure 4, in the present invention, the heat sink 30 is directly fixed to the fan type body 20 via the fastener 80. That is, in the related art, the short diameter portion of the cone body is fixed to the fan type main body, but in the present design, there is a big difference in that the heat sink 30 is directly fixed to the fan type main body 20. To this end, the U-shaped fastener 80 shown in FIG. 4 is used. The c-shaped fastener 80 is inserted into the heat dissipation plate 30 from the left side of the heat dissipation plate 30, and both ends thereof pass through the heat dissipation pipe 60 to be fastened to the fan type body 20 with the nuts 81.

Therefore, as shown in FIG. 6, two supporting holes 35 are formed at the center of the heat sink 30 so that both ends of the U-shaped fastener 80 are inserted. In addition, between the support holes 35 are connected to each other by the receiving groove 36, the center portion of the c-shaped fastener 80 is accommodated in the receiving groove (36). Therefore, as shown in FIG. 4, the U-shaped fastener 80 does not protrude to the outer surface of the heat sink 30, so that the U-shaped fastener 80 does not protrude from the outer surface of the heat sink 30, and is more favorable than the glass. Do. Apparently most preferred, the central portion of the U-shaped fastener 80 is flush with the left side of the heat sink (30).

As described above, according to the present invention, since the heat dissipation tube is in the form of a fallopian tube, there is an advantage in that the heat dissipation area is significantly expanded than the conventional cone body. In addition, the fallopian tube-type heat pipe is changed from the conventional ceramic material to a lightweight metal, thereby reducing the weight of the heater. Therefore, the phenomenon that the heat sink is sag can be suppressed.

In particular, since the heat sink is directly fixed to the fan-shaped body by the U-shaped fastener, it is possible to fundamentally prevent the heat sink from falling in addition to the weight reduction. As a result, it is possible to prevent the heat sink from crashing and damaging an expensive halogen heater.

Since the portion where the heating wire is exposed to the outside becomes significantly shorter than before, the phenomenon in which the heating wire melts due to high heat can also be suppressed. In addition, since the heating wire is a metal material and is disposed inside the heat sink in the form of a fallopian tube, the heat inside the heat dissipating tube is quickly discharged to the outside to prevent the heating wire from melting or burning.

Although the present invention has been described in detail with respect to the preferred embodiment of the present invention, the present invention is not limited to the above embodiments and the present invention without departing from the gist of the present invention claimed in the following utility model registration claims Anyone with ordinary knowledge in the field will be able to make various changes.
