【Example】

1 to 3 show a first embodiment of a heating and evaporating apparatus according to the present invention. FIG. 1 is a side view, FIG. 2 is a front view in an open state, and FIG. It is a schematic perspective view of. In each of the figures, reference numeral 1 denotes a main body of the heating and evaporating apparatus, and a front face portion 2 of the main body 1 of the apparatus is provided with a bottle insertion portion 4 formed of a concave portion adapted to the shape of the bottle 3. The ceiling part 5 of the apparatus main body 1 above the bottle insertion part 4 protrudes forward to form a semicircular eave part 6. The ceiling portion 5 has a transpiration hole 7 located just above the bottle insertion portion 4. A heating element 8 made of a material having excellent thermal conductivity is provided on an upper portion of the bottle insertion section 4 so as to protrude forward.
For example, in a plan view seen from above, the heating element 8 is formed in a substantially U-shape or a substantially U-shape having an opening 8a. Have been. The heating of the heating element 8 is performed, for example, by heating the heating element 8.
This is performed by energizing the positive-characteristic thermistor element connected in series through the power supply cord 10. The heating element 8 is configured such that the thickness on the opening 8a side is gradually increased, and the inside at the lower end is cut out in a tapered shape. On the upper side of the front part 2 of the apparatus main body 1, a left side edge part thereof is a front door 11 attached to the apparatus main body 1 by a hinge member.
Is provided to prevent the bottle 3 from coming off the bottle insertion portion 4 when the front door 11 is closed. A hook 12 is provided on the right side edge of the front door 11, and when the front door 11 is closed, the hook 12 is inserted into a hook hole 13 of the front part 2 of the apparatus body 1. It is stopped and locked. The bottle 3 contains, for example, an insecticidal solution for insecticidal purposes,
An aspirating liquid such as an aromatic liquid for the purpose of fragrance is filled, and a liquid absorbent core for evaporating the chemical liquid upward from the mouth 3a of the bottle.
14 is projected. Next, the operation of the heating and evaporating apparatus configured as described above will be described. The bottle 3 is inserted into the bottle insertion section 4 of the apparatus main body 1.
In this case, first, the front door 11 is opened, and the absorbent core 14 of the bottle 3 is opened.
The bottle 3 is inserted in the horizontal direction such that the bottle 3 is positioned at the liquid-absorbing core insertion portion 9 of the heating element 8. Therefore, the bottle 3 having the liquid absorbent core 14 can be taken in and out of the apparatus main body 1 in a substantially horizontal direction.
14 does not interfere with the heating element 8 and the apparatus main body 1, and the liquid absorbent core 14 is prevented from being damaged. Further, when the bottle 3 is inserted into the bottle insertion section 4 of the apparatus main body 1, there is no need to tilt or rotate the bottle 3, and therefore, there is no spilling of the chemical solution in the bottle 3. Next, the front door 11 is closed. In this state, a current is supplied to the positive temperature coefficient thermistor element to heat the heating element 8.
Is heated, the liquid absorption wick 14 is heated, and the evaporated liquid evaporates and is released from the evaporation hole 7 to the atmosphere. During this heat evaporation, the liquid absorbent core 14 is heated substantially uniformly from the surroundings. That is, since the heating body 8 is provided with the opening 8a for the liquid absorbent core 14 to enter, there is no heating body on the side of the opening 8a. The thickness m of the heating element 8 on the side is configured to be thicker than the depth (non-opening) 8b side, as if there is no heating element on the side of the opening 8a. The difference is reduced and the absorbent core 14
Is heated almost uniformly from the surroundings. Furthermore, since the lower end portion of the heating element 8 is tapered, air easily flows in from the periphery thereof, and an updraft is easily formed. That is, when the inner shape of the heating element 8 is vertical, the space between the liquid absorbing core 14 and the heating element 8 is small, and the air is unlikely to rise from the bottom to the top. If the area between the heating body 8 and the liquid absorbent core 14 is increased toward the lower side, air easily flows in as shown in FIG. As a result, the chemical solution is effectively dispersed in the air. FIG. 4 and FIG. 5 are schematic views of a main part showing a second embodiment and a third embodiment of the heating and evaporating apparatus according to the present invention. Those of these embodiments are the same as those of the first embodiment,
Since only the shape of the inner cutout at the lower end is different, a detailed description is omitted. FIG. 6 is a schematic view of a main part showing a fourth embodiment of the heating and evaporating apparatus according to the present invention. In the heating and evaporating apparatus of the previous embodiments, the mounting and dismounting of the bottle 3 was good by the horizontal movement, whereas in the present embodiment, the opening 8a was formed in the heating body 8. In this case, the mounting and dismounting of the bottle 3 must be performed in the vertical direction, which is the axial direction of the absorbent core. However, even in the present embodiment, the inside of the lower end portion of the ring-shaped heating element 8 is provided with, for example, a tapered notch, so that the area between the heating element 8 and the liquid absorption core 14 is reduced. Is bigger on the lower side, air easily flows in from here,
Since a rising airflow is likely to be formed, the liquid medicine from the heated liquid absorbing core 14 is effectively dispersed in the air. The present embodiment also has a feature that the liquid absorbent core 14 can be easily inserted into the ring-shaped heating element 8.
