[0026]
FIG. 8 is a circuit diagram of the present embodiment. In FIG. 8, 50 is an AC power supply and 51 is a DC power supply. The heating element 10 includes a relay contact 52a of a relay 52 connected in series with an AC power supply 50, and a relay coil 52b for controlling the relay contact 52a. It is designed to close. The energizing switch 53 can open and close the relay contact 52a by pressing a switch 53a for operating the relay 52. Reference numeral 22 denotes a light source using a plurality of LEDs. Reference numeral 54 denotes a microcomputer (hereinafter, abbreviated as a microcomputer) that executes a program that causes the LED to emit light at a specific cycle.

Reference numeral 21 denotes a control unit.
[0027]
The control unit 21 is held by vertically sandwiching the control unit holding ribs 60 provided in the storage portion 25 and the control unit 21 holding boss 61 adjacent to the through hole A43 of the lower frame 34. At this time, since the gap Y formed by the rib 60 and the holding boss 61 is set to be larger than the thickness Z of the base 62 of the control unit 26, the upper surface 45 of the boss 27 and the lower frame 34 penetrate during assembly. The end surface 46 of the hole A43 is not hindered from being closely attached. 63 is a hole provided in the lower frame. Reference numeral 64 denotes a container placed on the heating plate 7. The control unit 21 is configured to be able to hold the lower frame unit 31 at the same time when the lower frame unit 31 is attached to the column 16.
[0028]
Reference numeral 65 denotes a lid having a plurality of opening holes a66 at an upper portion for making it difficult to easily touch the container 64 when the heating body 10 is heated after the tea leaves are put into the container 64. An opening b is also arranged at the lowermost part of the lower frame 34. 67 is an installation surface on which the fragrance of the present invention is placed.
FIG. 9 is a diagram showing a state where the fragrance device of the present invention has fallen, and FIG. 10 is a diagram showing a state where the fragrance device is placed on an uneven installation surface.
[0029]
The operation of the above configuration will be described. When a tea leaf, which is an aromatic material, is put into the container 64 and the lid 65 is set, and then the power switch 53 is operated, the heating element 10 starts to generate heat and emits light from the light source 22 at the same time. Can be seen from the outside via a light source cover 28, a support 23, and an outer frame 29 which are transparent members. When the heating element 10 generates heat and overheats the container 64, the heating element unit 3 generates heat. The heating unit 3 is covered with the outer frame 29 on the side and the upper frame 2 on the side, so that the user cannot easily touch it during energization. Further, since the mounting of the upper frame unit of the support 16 is engaged at a position distant from the heating unit 3, it is less affected by the heat of the heating unit 10. Therefore, the arm of the column 16 is less susceptible to changes over time due to heat. In addition, since the support 10 is pivotally engaged with the upper frame unit 1, the support 10 is attached, so that the shape inside the outer frame 29 is facilitated. As a result, the light source 22 emits light to the outer frame 29. Shadow reflection can be reduced.
[0030]
During energization, the inside of the outer frame 29, which is heated to a high temperature by the heating unit 3, is discharged from the opening a 66 of the lid 65 through the upper opening 15 through the opening b of the lower frame 34. It is possible to prevent the temperature from rising due to the heat conduction of the heat exchanger 29.
[0031]
Heat generation by the heating element 10 is continued until the switch 53 is operated or a predetermined time elapses by the microcomputer. Therefore, during this time, the scent of the fragrance material and the light of the light source 22 can be used with confidence.
[0032]
If the fragrance device suddenly falls down during use, the lever 38 releases the switch operating portion 37 by the first biasing member 68 to set the switch 36 to the "open" state as shown in FIG. It is a safety device that stops the energization of 10.
[0033]
The movable range of the lever 38 is regulated by a lever sliding portion 39 constituted by the lower frame 34 and the lower frame cover 35. When the lever 38 is restricted from being pushed by the lever stopper 42, the inside of the lever 38 is restricted. By the action of the second urging member 69, the push rod 40 can prevent the switch 36 and the base 62 of the control unit 21 from overloading.
[0034]
FIG. 10 shows a state in which the lever 38 is restricted from being pushed by the lever stopper 42 when the fragrance device of the present invention is placed on the uneven installation surface. By the action of the second biasing member 69, the switch 36 and the base 62 of the control unit 21 can be used as usual so as not to overload.
[0035]
【The invention's effect】
As described above, according to the present invention, by covering the heating element with the outer frame, it is possible to generate heat only in the portion that heats the fragrance material, thereby preventing the user from accidentally touching the heat source. It becomes possible. In addition, by notifying the energization of the heating element by the light emission of the light source and performing the effect by the light at the same time, it is possible to provide a fragrance device that is comfortable and can be used with confidence for a long period of time.
