However, if the material to be heated 10 is used in a ceramic or metal container, the material to be heated 10 can be easily put in and taken out. Further, if a hole is made in the bottom of the container, or if it is formed in a stitch shape or a lattice shape, air convection is likely to occur, and fragrance is likely to occur.
Further, it is desirable to use a compound for the contact member with the heater 5 to improve heat conduction.
[0027]
In addition, the number of LED1, the voltage of LED1, and the voltage of the heater 5 are not specifically limited. Further, a plurality of LEDs 1 are used and each of them is simply lit in Reference Example 1. However, by shifting the lighting timing of each, it becomes possible to produce the light from LED 1 more blurry and like a flame.
[0028]
(Example 1 )
FIG. 2 shows an aroma apparatus according to the first embodiment. Since the basic configuration is the same as that of the reference example 1, the same reference numerals are given to the same portions, the description thereof is omitted, and differences will be mainly described.
[0029]
In this embodiment, three LEDs 1 are provided on the substrate 2 at intervals of 120 °. Further, each of the upper portion of the first cover 3 that diffuses and transmits the light of the LED 1 and the substrate 2 of the LED 1 are provided with holes of φ4 mm, through which the heater wiring 12 passes. The heater wiring 12 is configured to rise from the center of each LED 1. The heater 5 is disposed above the LED 1 and is connected to the heater wiring 12.

The operation of the fragrance with the above configuration is the same as in Reference Example 1, but by raising the heater wiring 12 from the center of each LED 1, the light of the LED 1 is behind the heater wiring 12 in any direction. Instead, the shadow of the heater wiring 12 can be removed from the light of the first cover 3 by directly emitting light to the first cover 3.
[0031]
Further, by using the heater wiring 12, the heater wiring 12 is shortest to the heater 5, and further, the heater wiring 12 can be arranged from the second cover 4 to the longest, and the shadow by the heater wiring 12 is made invisible. I can do it.
[0032]
Note that the upper portion of the first cover 3 and the hole of the LED substrate 2 may be of a size that allows the heater wiring 12 to pass therethrough, and no special processing is required.
[0033]
(Example 2 )
FIG. 3 shows an aroma apparatus in Example 2 . Since the basic configuration is the same as in Reference Example 1 and Example 1 , the same parts are denoted by the same reference numerals, description thereof will be omitted, and differences will be mainly described.

[0036]
In addition, the shade by the heater wiring 12 can be made further invisible by setting the color tone of the holding pipe 13 to a lighter color tone similar to the light emission color of the LED 1.
[0037]
Further, by using a PTC heater for the heater 5, it becomes possible to prevent the temperature from becoming higher than the Curie temperature, and the aroma can be used more safely. In the candle type, since the distance between the candle and the heating surface changes every time or during use, it is not easy to obtain the optimum maximum surface temperature. However, the material to be heated 10 of the heating plate 6 is not used as in this embodiment. Heating sencha or roasted tea and enjoying aroma components by setting the maximum surface temperature of the heating surface to 160 ° C or higher by selecting the Curie temperature of the PTC heater and selecting the thickness and material of the heating plate 28 Is possible.
[0038]
On the other hand, by selecting the Curie temperature of the PTC heater and the thickness and material of the heating plate 6, by setting the temperature to 300 ° C. or less, it is possible to suppress the generation of a burning smell that occurs with the aroma component.
[0039]
In addition, since it becomes possible to generate an aroma component for a long time by setting the surface maximum temperature of the heating surface of the heating plate 6 to a temperature range of 160 ° C. to 240 ° C., as the surface maximum temperature of the heating surface, 160 ° C to 240 ° C is most desirable.
[0040]
(Example 3 )
FIG. 4 shows an aroma apparatus in Example 3 . Since the basic configuration is the same as that of Reference Example 1 and Examples 1 and 2 , the same portions are denoted by the same reference numerals, description thereof is omitted, and differences will be mainly described.
[0041]
In this embodiment, a load applied in the vertical direction of the second cover 4 is held by a fixing material 14 made of a transparent polycarbonate resin provided inside the second cover 4. And the fixing material 14 makes the shape of the part which corresponds to the attachment position of LED1 substantially cylindrical shape. The substantially cylindrical portion is desirably higher than the substantially cylindrical portion shown in the drawing.
[0042]
Such an fragrance uses a fixing material 14 made of a transparent polycarbonate resin to hold the second cover 4 made of glass in the vertical direction, thereby reducing the force applied to the glass without adversely affecting the light of the LED 1. It becomes possible to reduce.
[0043]
The fixing material 14 may be any material as long as it can hold the glass in the vertical direction and is transparent, but since it is in the vicinity of the heater 5, a polycarbonate resin having high heat resistance is desirable.
[0044]
Further, the shape of the fixing member 14 may be any shape as long as the refraction of light by the fixing member does not adversely affect the light of the LED 1, but the substantially cylindrical shape that allows the light of the first cover 3 to be evenly transmitted. Is the best. In addition, it is possible to give the fixing member 14 other than the holding function as an internal component, but if at least a portion corresponding to the mounting position of the LED 1 is formed in a substantially cylindrical shape, light is transmitted from the side surface of the second cover 4 without unevenness. It is desirable because it becomes possible.
[0045]
It goes without saying that the configurations of the first to third embodiments are not limited to single configurations, but can be combined appropriately.
[0046]
【The invention's effect】
As is clear from the above embodiment, according to the fragrance device of the present invention, it is not necessary to replace the light source, and the light source is prevented from reaching a high temperature, and the first and second covers that diffuse and transmit the LED.
