The opening periphery of the holding member 6 is exposed to the outside through the opening of the lid cover 9. In use, the outer lid guard 12 is further placed on top.
An electrode 20 is attached to the heater 1, and a current flows through the heater 1 by turning on a power switch provided in the fragrance body.
[0023]
Operation | movement of the aroma apparatus of Example 1 of such a structure is demonstrated. A container 4 containing an appropriate amount of sencha is placed on the heating plate 3 and the power switch is turned on, whereby the heater 1 is heated and the heat of the heater 1 is made of metal through the conductive plate A2 having good thermal conductivity. It is efficiently transmitted to the heating plate 3 and the container 4 and aroma components from sencha are generated. The flow of air containing a fragrance component reaches the user through the plurality of air openings of the outer lid guard 12. By fitting a portion corresponding to the upper periphery of the heating plate 3 of the upper cover 6a (peripheral portion (opening peripheral portion) of the opening of the upper cover 6a) inside the opening of the lid cover 9, the heat of the heater 1 is heated inside the main body. By covering the remaining upper cover 6a with the lid cover 9 while avoiding clogging, it is possible to lower the temperature of the lid cover 9 that is a portion that is touched by a person at the top of the main body. For this reason, in the first embodiment, PET resin, PBT resin, or a mixture of PET resin and PBT resin, which has excellent gloss, can be used as the lid cover 9.
[0024]
Further, by lowering the temperature inside the lid cover 9 and the main body, the temperature rise of the body 11 which is the outer shell can be suppressed. Further, by covering the heater 1 with the upper cover 6a and the heater cover 6b as in the first embodiment, the ambient temperature in the outer shell is suppressed, and the temperature of the lid that covers the outer body and the upper portion of the body is lowered. I can do it. Further, since the space 10 is provided between the lid cover 9 and the holding member 6, the conduction heat from the holding member 6 to the lid cover 9 can be reduced, and the temperature rise of the outer shell can be suppressed.
In addition, although the PTC heater was used for the heater 1 in the present Example 1, as long as it is a structure like this Example 1, any heater will be heated to temperature sufficient to generate a fragrance component from sencha or black tea. It is possible to suppress the temperature rise of the outer shell.
[0025]
Further, the heat of the heater 1 is transmitted to the heater cover 6b through the heater spring 8, but since a coil spring is used for the heater spring 8, heat conduction to the heater cover 6b is suppressed. If only the purpose of energizing the heater 1 is used, the same effect can be obtained even if another spring such as a leaf spring is used.
In the first embodiment, the upper cover 6a and the heater cover 6b are fitted without using screws, but may be further tightened with screws after the fitting, or only the screws without being inserted and rotated. It is possible to assemble even if tightened with.
[0026]
Example 2
The aroma apparatus of Example 2 of this invention is demonstrated using FIG. FIG. 4 is a cross-sectional view of the fragrance according to the second embodiment of the present invention cut along a vertical plane passing through the center thereof.
41 is an upper cover which covers a heating plate from the top. A heater cover 42 covers the heating plate from below. Reference numeral 43 denotes a lid cover that fits into the upper cover. An air port 44 is provided at the center of the side end of the lid cover 43, and a portion corresponding to the inside of the air port 44 (the air port 44, the upper cover 41, and the heater cover 42). A wall 43a is provided at a position separating the space between the contact surface and the contact surface. The wall 43a is formed below a contact surface (a fitting surface in the embodiment) between the upper cover 41 and the heater cover 42. The air opening is provided on the side surface of the lid cover 43 or on the contact portion between the body 11 and the side surface of the lid cover 43.
45 is a bottom plate and has an air port 46. The upper cover 41 is provided with a liquid reservoir 41 a in which a liquid such as water that has entered from a gap between the upper cover 41 and the lid cover 43 is stored. In other respects, the fragrance of the second embodiment is the same as that of the first embodiment.
[0027]
The aroma apparatus of the second embodiment performs substantially the same operation as that of the first embodiment. The aroma apparatus of the second embodiment can release the heat of the air inside the main body from the air port 44, and can lower the temperature of the body 11 that is the outer shell.
In addition, when liquid (for example, water) enters from the air port, the intruded liquid hits the wall 43 a provided on the lid cover 43 and falls downward. Since the lower end of the wall 43a is below the contact surface between the upper cover 41 and the heater cover 42, even if the infiltrated liquid rushes horizontally from the lower end of the wall 43a, the liquid does not move from the upper cover 41 to the heater cover 42. There is no risk of reaching the heater 1 through the gap. The wall 43a can prevent the liquid that has entered from adversely affecting the internal components of the main body such as the heater.
[0028]
If the fitting portion 29 between the upper cover 41 and the lid cover 43 is brought into contact with each other to make the gap small, even if water is accidentally poured into the gap (fitting portion) 29, The amount of water that enters the interior through the gap is small (it is difficult to prevent water from entering at all). The liquid reservoir 41a provided in the upper cover 41 can temporarily store the water that has entered the interior. The accumulated water can be gradually evaporated during use or standing. This can prevent adverse effects on the main body (for example, water can reach the circuit board 27 and cause malfunction or failure). The effect of providing the liquid reservoir 41a is great. Further, when the steps on both sides of the fitting portion 29 are set to substantially zero, water is more difficult to collect and dust is also difficult to collect.
