Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heater used for outdoor work and the like, and more particularly to a far infrared heater that emits far infrared rays.

[0002]

[Prior art]

 Traditionally, far infrared heaters have been used in places where it is desired to directly heat the human body without heating the space, such as in outdoor worksites, factories or driving ranges.

As the far-infrared heater, a sheath heater that radiates infrared rays in the far-infrared region is generally used, and a reflection plate provided on the back surface radiates the far-infrared rays in one direction. Has been done.

[0004]

[Problems to be solved by the device]

 However, with the above sheath heater, the temperature rises slowly after the power is turned on, so the waiting time until the heating function is exerted in the workplace is long, and therefore the working environment until the heater rises to the desired temperature is poor. It was

Further, since the surface temperature as a heat source is low, there is a limit to the heating capacity at a close position.

In view of the above problems, an object of the present invention is to provide a far-infrared heater which has a rapid temperature rise and exhibits sufficient heating capacity at a close position.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the far-infrared heater according to the present invention is a far-infrared heater having an element that emits far-infrared rays and a reflection plate that reflects far-infrared rays provided on the back surface of the element. It is characterized in that a halogen light bulb, which is curved so as to have a concave shape, is provided with a far-infrared heat-generating coating as the element in the concave portion of the reflecting plate.

[0008]

[Action]

 According to the above configuration, when the power is turned on, the halogen bulb with the far-infrared heating coating, which is an element that emits far-infrared rays, generates heat in a short time, so the heating capacity as a far-infrared heater that emits far-infrared rays in a short time Exert.

Further, the far infrared rays emitted are reflected by the reflection plate and radiated in a predetermined direction because the halogen bulb is provided in the concave portion of the reflection plate. It provides sufficient heating capacity even in close proximity.

Further, since the halogen bulb emits light as well as generating heat, it also has some function as a light source.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a far infrared heater according to the present invention, FIG. 2 is a side sectional view showing a heater portion, and FIG. 3 is a front view showing the heater portion.

As shown in the figure, a bowl-shaped rear guard 2 is provided on the front surface of the heater body 1, and a reflection plate 3 is provided on the front surface of the rear guard 2. A halogen bulb 4 with a far-infrared heating coating is provided at the center of the reflector 3, and a front guard 5 for preventing contact with the halogen bulb 4 is provided on the front surface thereof. There is. These are supported by the legs 6 together with the heater body 1, and are configured so that they can be adjusted to an arbitrary height by an adjusting member 6a provided on the legs 6.

The reflector 3 has a bowl shape curved so that the central portion is concave. Even if the halogen bulb 4 is attached to the central concave portion 3 a, the top portion 4 a of the halogen bulb 4 is not removed. It is formed so as to have a depth that does not project from the peripheral edge portion 3b of the reflection plate 3. Further, the reflector 3 is provided so as to be separated from the rear guard 2, so that heat when functioning as the reflector 3 is prevented from propagating to the rear guard 2 side.

The result of measuring the temperature rise by the far infrared heater H configured as described above under the conditions of the model diagram shown in FIG. 4 will be described below. As a condition, the distance between the front surface of the far infrared heater H and the temperature sensor S was set to 400 mm, and the temperature rise at room temperature after the power was turned on was measured.

FIG. 5 is a diagram showing the temperature rise of the above measurement results. When the temperature rise of the sheath heater and the temperature rise of the far infrared heater H in the present invention are compared based on this diagram, the sheath heater shows While the temperature rises from about 2 to 3 minutes after the power is turned on, the far infrared heater H of the present invention shows a clear temperature rise after the power is turned on.

This difference takes about 1 minute for the far-infrared heater H of the present invention, while it takes about 3 minutes and 20 seconds for the sheath heater when the temperature rises by 2 ° C. after the power is turned on. In other words, it can be seen that the far infrared heater H of the present invention has a speed of three times or more. Further, it takes about 9 minutes for both heaters to reach the same temperature, and it can be seen that far-infrared heater H of the present invention is far superior in heating capacity until then.

As described above, according to the far-infrared heater H of the present invention, the time from power-on to heat generation is short, and the far-infrared heating coating applied to the halogen bulb 4 enables power-on. Far infrared rays can be radiated from the heater to exert the heating function as the far infrared heater H.

Although a circular heater is used as an example in the above embodiment, a heater having a polygonal or rectangular reflector may be used.

Although not shown in the above embodiment, a power switch and an automatic power cut-off mechanism at the time of tilting, which has been used for a general heating appliance in the past, are appropriately adopted in the heater body 1. ing.

[0020]

[Effect of device]

 According to the present invention, since the halogen bulb in which the far-infrared radiation element is coated with the far-infrared heating coating is used, the time from turning on the halogen bulb to generating heat is short, and the far-infrared heating coating is provided after the power is turned on. Emit far infrared rays. Therefore, the time until the heating function of the far infrared heater is exerted can be greatly shortened.

Further, since the halogen bulb is provided in the concave portion of the reflector, far infrared rays emitted from the halogen bulb are reflected by the reflector and radiated in a predetermined direction, resulting in good heating efficiency and close proximity to the heater. The heating capacity at the selected position is also greatly improved.

Further, since the halogen bulb is used as the far-infrared ray radiating element, there is an effect that light is emitted together with heat generation and the light source exhibits some functions as a light source.
