DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

TECHNICAL FIELD The present invention relates to a heat evaporation device for heating and evaporating a chemical solution such as a fragrance or an insecticide.

BACKGROUND OF THE INVENTION

As a heating and evaporation device for heating and evaporating a chemical solution such as a fragrance or an insecticide, for example, as described in Japanese Utility Model Application Laid-open No. 58-45670, a bottle is placed on a bottom cover, and a closed bottomless cylindrical main body is used. A bottom lid is fitted from the bottom side, or Kimiaki Jitsu
As described in JP-A-44-8361, there is a method in which a bottle is inserted from the bottomless side of a closed-bottomed cylindrical main body, and the mouth of the bottle is screwed into the main body. However, in the heating and evaporating apparatus described in Japanese Utility Model Application Laid-Open No. 58-45670, it is difficult to accurately fix the liquid-absorbing core to the heating element. There are problems such as poor evaporation. Further, the heating and evaporation apparatus described in Japanese Utility Model Publication No. 44-8361,
When the upper part of the core enters the interior, the insertion part becomes difficult to see,
The upper part of the core often hits the inner wall, and is liable to be broken, failing to obtain good transpiration, and having difficulty in mounting the bottle. Therefore, as a means to solve these problems, in a heating and evaporation device that evaporates the absorbed chemical by heating the absorbent core partially immersed in the chemical of the bottle,
The apparatus main body is provided with a bottle insertion portion capable of taking the bottle in and out of the bottle from a substantially horizontal direction, and a heating element is provided on an upper portion of the bottle insertion portion. A device having a U-shaped liquid absorbent core insertion portion has been proposed (Japanese Utility Model Application Laid-Open No. 63-84240). In this device, a bottle having a liquid absorbent core can be inserted into and removed from the apparatus body in a substantially horizontal direction. This can be simplified because the liquid absorption core does not interfere with the heating element and the apparatus main body when the bottle is set, preventing the liquid absorption core from being damaged and further increasing the heat generation of the bottle. It is said that it can be kept in a state of being set well on the body and the like. And, although this is an excellent one, it has a substantially U-shaped liquid-absorbing wick insertion portion in which the liquid-absorbing wick of the bottle can be taken in and out of the heating element from the horizontal direction. At the U-shaped tip (U-shaped opening) side, the temperature is relatively low, and the liquid absorbent core is difficult to be uniformly heated from the periphery, and it is difficult to obtain good transpiration. Have been.

【Example】

1 to 4 show one embodiment of a heating and evaporating apparatus according to the present invention, wherein FIG. 1 is a plan view, FIG. 2 is a side view, FIG. 3 is a front view in an open state, FIG. 4 is a schematic perspective view of a main part. 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.
The heating element 8 has a substantially U-shape having an opening 8a, for example, in a plan view seen from above, and the U-shaped groove portion is formed in the liquid-absorbing core insertion section 9. The heating element 8 is heated by, for example, energizing a positive temperature coefficient thermistor element connected to the heating element 8 via a power cord 10. In particular, the heating element 8 is formed such that the thickness on the opening 8a side is gradually increased. 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, so that the mounting (and detaching) operation is easy, and the liquid absorbent core is set when the bottle is set.
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 made thicker than the depth (non-opening) 8b side, so that it compensates for the absence of the heating element on the side of the opening 8a. And the liquid absorbent core 14 is heated substantially uniformly from the surroundings. In addition, even if the width dimension of the opening 8a side is increased instead of the thickness dimension m of the heating element 8, it is possible to make up for the absence of the heating element at the opening 8a side, but it is expanded toward the inside. In this case, the opening size of the opening 8a becomes narrow, which makes not only the insertion operation of the bottle 3 difficult, but also the insertion
Is more likely to be damaged. Further, if the width is widened toward the outside, the heating effect is so poor that the technique is inferior to the present invention even if the width of the opening 8a side is increased both inside and outside.

【effect】

The heating and evaporating apparatus according to the present invention is provided with a heating mechanism having a trace cutout portion and a bottle mounting portion, and heating the core of the bottle mounted on the bottle mounting portion with the heating mechanism to cause the liquid in the bottle to heat. In the heating and evaporating apparatus for evaporating, the size of the heating mechanism in the core direction of the bottle is configured to be substantially large on the side of the trace cutting portion, so that the bottle having the core can be taken in and out of the mounting main body from, for example, the horizontal direction. It is excellent in workability, and although the heating ratio is small in the part of the trace notch provided in the heating mechanism, the size of the heating mechanism on the trace notch side is large, so it is as if It compensates for the lack of a heating mechanism on the trace cut side, so the difference in temperature distribution is reduced accordingly, the core is heated almost uniformly from its surroundings, and Excellent heating condition, with the characteristics of equal transpiration degree of liquid is good.
