In this case, since the slit holes 11 and 11 ′ through which the heated air is discharged are formed in the edges 12 and 12 ′, the body 10 can be compactly realized and the weight can be reduced. These slit holes (11, 11 ') is connected to the space portion 13 is formed inside the body (10).

On the back side of the reflecting plate 20, a plurality of first heat radiating fins 22 for dissipating heat of the reflecting plate 20 to the space 13 of the body are formed at regular intervals.

The reflecting plate 20 reflects most of the near infrared rays irradiated from the near infrared lamps 30 and 30 'but absorbs some of them. In addition, since the reflector 20 is located close to the near infrared lamps 30 and 30 ', the heat of the near infrared lamps 30 and 30' heated to 2000 ° C or more is conducted to the reflector 20 through the air. In particular, when corrosion progresses on the surface of the reflector 20 over time, the reflectance drops sharply, in which case more near infrared rays are absorbed. For this reason, the temperature of the reflector plate 20 is maintained for more than a few hundred degrees, this heat is transferred to the first heat sink fin 22 is transferred to the space portion 13 of the body.

The near-infrared lamps 30 and 30 'are spaced apart from the reflecting plate 20, and are heated to 2000 ° C. or higher to irradiate near-infrared rays. Since the near-infrared lamps 30 and 30 'generate instantaneous infrared rays while being instantaneously heated, they have less calorie loss. In particular, near-infrared rays are short wavelengths having a wavelength in the range of 0.8 to 1.4 µm, so they go straight for more than 7 to 8 meters. It can heat up and penetrate deep into the skin to generate heat, which is good for your health.

The fan 40 introduces external air into the body 10 through the discharge port 41. The fan 40 is preferably a sirocco fan having a hexahedral shape as a whole and having a cylindrical blower. The air flowing from the fan 40 into the space 13 inside the body 10 is guided to the back side of the reflector 20 by the flow path forming portion 50, and then recovers the heat of the reflector 20, The recovered air is heated and then discharged through the slit hole 11 to heat the surrounding air.

The flow path forming portion 50 allows the air introduced into the body 10 by the fan 40 to remain in the space 13 for a long time, thereby enabling effective heat exchange with the reflector plate 20.

Has The guide grooves 73 of the docking bracket 70 to be described later are inserted into the guide grooves 63.

The docking bracket 70 has a plate shape as a whole, and a second plate 72 fixed to the wall W, and a guide protrusion 73 coupled to the guide groove 63 as formed in the second plate 72. And a magnet 74 attached to the rear surface of the guide protrusion 73.

The second plate 72 is fixed to the wall W by a bolt (not shown) or the like, and is made of a metal material that has sufficient durability and does not corrode even after a long time.

The guide protrusion 73 is formed to protrude from the surface of the second plate 72 as shown in FIG. 3 and is formed by punching out the second plate 72. The guide protrusion 73 is coupled to the guide groove 63 of the rotation support bracket 60, so that the rotation support bracket 60 can be coupled to the docking bracket 70 in the correct position.

The magnet 74 is installed inside the guide protrusion 73, and the first plate 62 and the second plate 72 may be attached by magnetic force when the guide protrusion 73 is inserted into the guide groove 63. Make sure It is preferable that this magnet 74 is a neodium magnet.

As shown in FIG. 3, the first connection terminal 81 includes a first insulator 81a that is electrically insulated from the first plate 62, and a first terminal 81b that is provided in the first insulator 81a. ) And a spring 81c for elastically pressing the first terminal 81b toward the second connection terminal 82 side.

As shown in FIG. 3, the second connection terminal 82 includes a second insulator 82a that is electrically insulated from the second plate 72, and a second terminal 82b that is provided in the second insulator 82a. ). In this case, the second insulator 82a is generally in the form of a disk, and the second terminal 82b is provided through the center of the second insulator 82a. The second terminal 82b is connected by a constant power source and a power line of an outlet of the wall W.

The first connecting terminal 81 and the second connecting terminal 82 are installed at positions that can be mutually connected when the guide protrusion 73 is correctly fitted in the guide groove 63. Accordingly, if the guide protrusion 73 is not correctly pinched in the guide groove 63, the first connection terminal 81 and the second connection terminal 82 are also not connected.

 The fan controller 90 controls the operation of the fan 40 in association with the temperature of the air discharged to the slit holes 11 and 11 ′. As shown in FIG. 2, the fan controller 90 includes a sensor 91 for generating a corresponding temperature signal by measuring a temperature of air discharged and installed in the slit holes 11 and 11a, and a sensor ( And a controller 92 for controlling the power applied to the fan 40 in association with the temperature signal generated at 91.

When the reflector 20 is not sufficiently heated by the fan controller 90 and the air passing through the slit holes 11 and 11 'is not sufficiently heated, the sensor 91 measures the corresponding temperature signal. The controller 92 stops the operation of the fan 40 in association with the temperature signal. When the reflector 20 is sufficiently heated and the air passing through the slit holes 11 and 11 'is sufficiently heated, the sensor 91 generates a corresponding temperature signal, and the control unit 92 interlocks with the temperature signal. The fan 40 is operated, and thus air is heated while passing through the first and second heat dissipation fins 22 and 52, and then discharged through the discharge holes 11 and 11 ′. In other words, the fan controller 90 detects whether the air is sufficiently heated by the reflector 20 and then discharges the air when the air is sufficiently heated to enable heating by convection.

Next, the operation of the near-infrared heater of the compact structure of the above-described structure will be described.

First, the docking bracket 70 is fixed to the upper side of the wall W by a bolt (not shown), and the power line W connected to the second connection terminal 82 is connected to the constant power of the outlet C. .

Next, the guide protrusion 73 is inserted into the guide groove 63 in a state where the first plate 62 of the rotation support bracket 60 is in close contact with the second plate 72 of the docking bracket 70. Then, the magnet 74 installed in the guide protrusion 73 attaches the first plate 62 to the second plate 72. In this state, the first connecting terminal 81 connected to the near-infrared lamps 30 and 30 'of the body 10 is connected to the second connecting terminal 82 and electrically connected thereto.

Next, power is applied to the near-infrared lamps 30 and 30 '. Then, near-infrared lamps 30 and 30 'are heated to 2,000 ° C. or higher, and near-infrared rays are irradiated to the front, and the near-infrared rays irradiated to the rear are reflected from the reflector 20 and then heated forward.

Meanwhile, near-infrared lamps 30 and 30 ′, which are heated to 2,000 ° C. or more, heat the temperature of the reflector 20 to several hundred degrees or more, and the heat is transferred to the first heat dissipation fin 22. In this state, when the fan 40 is operated to supply air into the body 10, the air passes through the first and second heat radiation fins 22 and 52 in a zigzag form via the flow path forming unit 50, and the air The heat is recovered by recovering the heat transferred to the first heat sink fins 22. The heated air is discharged through the slit holes 11 and 11 'to heat the air around the body 10. That is, the heat transferred to the reflector 20 may be used to heat the air to maximize the heating efficiency.
