are provided, and these connection terminals 36, 37, 38 are connected to the corresponding connection pins 26, 27, 28 when the power supply plug 33 is attached. Furthermore, the power supply plug 33 has a built-in temperature sensor 39 such as a posistar that senses the temperature inside the tower 1, and an electronic control circuit (not shown) in the controller 34 is activated based on the temperature detected by the temperature sensor 39. The power supply to the heaters 11, 11 is controlled, thereby maintaining the temperature inside the tower 1 at a set temperature. Note that 40 is a guard that covers the opening on the lower surface of the storage section 5.

Next, we will discuss the effect.

When electricity is applied to the heaters 11, 11, these heaters 11, 11 reach a high temperature of 600°C or more and become red hot, and near infrared rays with a wavelength of 0.76 to 3 μ are radiated from their surfaces, and this near infrared rays are transmitted through the irradiation holes 20... The central part of the interior of 1 is irradiated. Also, the cover 18 is damaged by the radiant heat from the heaters 11, 11.
It is heated to about 100℃, and the cover 18 is heated accordingly.
Far-infrared rays having a wavelength of 3 to 25 μm are irradiated from the outer surface of the tower 1 to the inside of the tower 1 through the far-infrared layer 19.
Since the cover 18 is formed in the shape of an inverted truncated quadrangular pyramid, this far infrared rays are evenly distributed to the inner peripheral part and the central part of the tower 1 through the horizontal plane at the center and each surrounding slope. and uniformly irradiates the entire area inside. On the other hand, when the motor 14 is energized, the fan 16 rotates, and in response to this rotation, air in the central portion of the interior of the tower 1 is sucked into the inside of the cover 18 through each suction hole 21. Here, the air flowing in from the inner suction holes 21a... passes through the inside of the rectifying ring 17, and the air flowing in from the outer suction holes 21b... passes through the outside of the rectifying ring 17, while being rectified. The radiant heat from the heaters 11, 11 transforms the air into hot air, which blows into the tower 1 from each outlet 22.
It blows out towards the surrounding area inside.

In this way, in the central part of the interior of Yagura 1,
Near-infrared rays that heat quickly are irradiated, and far-infrared rays that are gentle and less irritating to the person taking the warmth are irradiated throughout the interior, and warm air is blown and circulated around the interior, so that it warms up. egoism,
In addition, every corner of the interior is heated evenly, providing comfortable heating conditions.

By the way, as a far-infrared ray irradiation type heat dissipation device, a mica heater is provided in close contact with the inner surface of the cover, and based on the heat generated by the mica heater, far-infrared rays are irradiated through the far-infrared layer on the outer surface of the cover. In the case of such a structure, the cover must be formed into a flat shape because the mica heater is in close contact with the inner surface of the cover.
This has the disadvantage that far infrared rays can only be irradiated in one direction, but in this embodiment, the heaters 11, 11 are provided spaced apart inside the cover 18, which allows the cover 18 to be This has the advantage that it can be formed into a pyramid shape and that far infrared rays can be directed to various parts inside the tower 1.

The air inside the tower 1 is sucked into the inside of the cover 18 through each suction hole 21 as described above, but this air is rectified by the rectifying ring 17 so that it is smoothly diffused around the outer circumference. Therefore, part of the warm air heated by the heaters 11, 11 does not inadvertently circulate around the motor 14, and the rectifying ring 17 prevents the heaters 11, 11 from inadvertently circulating around the motor 14.
Radiant heat directed toward the motor 14 is mechanically blocked, and therefore overheating of the motor 14 can be reliably prevented.

Heaters 11, 1 arranged inside the reflector 10
Each component such as 1 and motor 14 is integrally covered with a cover 18 that also serves as a basic member for far-infrared irradiation.
This single cover 18 can prevent foreign matter from entering into the portion where it is disposed, which is advantageous in terms of cost and assembly work. Further, the support plate 12 that supports the motor 14 is arranged in a dead space between the motor 14 and the fan 16, and therefore there is no need to secure a separate space for the support plate 12, and the screws 13... The protruding end of the kotatsu unit 7 does not interfere with other installed parts, which has the advantage that the kotatsu unit 7 can be made even more flat.

〔Effect of the invention〕

As explained above, according to the present invention, the central part of the inside of the tower is irradiated with near-infrared rays that have excellent heating properties, the entire area of the inside is irradiated with gentle and less irritating far-infrared rays, and the surrounding parts of the tower are further irradiated with far-infrared rays that are gentle and less irritating. By blowing and circulating warm air, we have the advantage of not only being able to start up quickly, but also warming every corner of the inside of the tower, keeping the overall temperature distribution even, and creating a pleasant and comfortable heating condition. play.
