2. Description of the Related Art For example, a heating evaporator for deodorizing a room by vaporizing and evaporating a liquid such as a chemical liquid is disclosed in Japanese Patent Application Laid-Open No. 8-148. Have been.

[0003] An outline of the heating evaporator is as follows. A heating element such as a heater is provided in an evaporator main body in which a liquid container is set at a lower portion, and heat is applied to a liquid absorbing core for sucking up a chemical solution in the liquid container by the heating element. By giving, it has a structure that promotes vaporization and transpiration, and diffuses outside through a transpiration port provided above the evaporator body.

[0004]

The liquid absorbing wick is heated to promote the vaporization and transpiration of the chemical solution, and is diffused outside from the upper transpiration port.

[0005] In the diffusion from the transpiration port to the outside, air is taken in from the bottom of the vessel from a place where an efficient state is ensured by reliably generating an upward flow toward the transpiration port.

Since a liquid container is inserted and set in the lower part of the container, air is taken in by securing a gap between the container and the liquid container. It is difficult to obtain a reliable upward flow. For this reason, it is sufficient to increase the gap, but in this case, it is possible to reduce the size of the liquid container while leaving the container as it is, or to achieve this by increasing the container while leaving the liquid container as it is. Is limited by the size of the liquid container.
In the latter case, a problem such as an increase in the overall size is caused.

In the type in which the liquid container is inserted and set directly in the lower part of the container, no gap can be formed,
There was a problem that it could not be adopted depending on the type of insertion of the liquid container.

In view of the above, the present invention enables reliable intake of air without being affected by the liquid container and secures an optimal upflow corresponding to the size of the room. It is intended to provide a heating evaporator.

According to the first aspect of the present invention, there is provided a liquid container provided with a liquid absorbing core for sucking a chemical solution therein, and the liquid container is set at a lower portion. The evaporator body having a transpiration port in the upper part, a heating unit fixedly supported in the evaporator body and heating the liquid absorbent core, and an air inlet provided on a side surface of the evaporator body below the heating unit. It is characterized by having.

[0010] This ensures that the air taken in from the air inlet has a reliable upward flow toward the upper evaporation port.
At this time, the air is taken in without being disturbed by the liquid container inserted and set at the lower part.

According to a second aspect of the present invention, a plurality of air inlets are provided at positions facing each other with the same opening area as the liquid absorbent core.

As a result, it is possible to obtain a reliable ascending flow which gathers from the left and right to the central portion and merges upward, and can efficiently diffuse outside from the transpiration port.

According to the third aspect of the present invention, the opening area of the air intake can be adjusted by the intake opening / closing control means.

Thus, by increasing or decreasing the opening area of the air intake, it becomes possible to control the optimal amount of air intake corresponding to the size of the room and the installation location.

According to a fourth aspect of the present invention, the air inlets are arranged at positions facing the liquid-absorbing wick, respectively. The opening area can be adjusted so that substantially the same amount of air is taken in.

This makes it possible to control the amount of air taken in from the left and right air inlets to the center and to rise toward the upper transpiration opening. For example, when the room is small, the amount of air taken in is reduced. If the room is large, increasing the amount of air intake ensures an optimum upward flow according to the size of the room.
