Description

  The present invention relates to a heating evaporator, and more particularly to a heating evaporator which is excellent in aesthetics and has no contamination of a main body case due to a chemical solution.

  2. Description of the Related Art Conventionally, heating evaporators that vaporize and evaporate chemical solutions suitable for room deodorization, aroma, insecticide, and the like have been widely used.

  This type of heating evaporator has a liquid container equipped with a liquid absorption core for sucking up the internal chemical solution installed in the lower part of the evaporator main body, and this liquid absorption by a heating element such as a heater provided in the evaporator main body. By heating the wick, vaporization and transpiration of the chemical solution is promoted, and the structure diffuses to the outside from the transpiration port provided above the transpiration device body.

  As a conventional heating vaporizer, a front case with a screw receiving boss, a mounting member having a through hole for fixing and supporting a heating element and a screw receiving boss being inserted, and a screw receiving boss inserted into the through hole There has been proposed one constituted by a main body rear case provided with a boss receiving portion for fastening the screw with a screw (for example, see Patent Document 1).

  3 to 5 again, a plug 7 and a power switch 12 are provided at the lower part of the heating evaporator 1, and the power switch 12 is electrically connected to a cord protector 72 provided at the tip of the power cord 71. The cord protector 72 and the operation unit 121 of the power switch 12 are exposed to the outside.

  Next, the usage method of the heating vaporizer of this embodiment is demonstrated.

  As shown in FIGS. 3 and 6, the liquid container is inserted into the main body 2.

  Thereafter, the plug 7 is inserted into an outlet, the power switch 12 is turned on, and the heating element 5 is energized.

  The heating element 5 that has generated heat by energization heats the liquid absorption core that sucks up the chemical liquid from the surroundings to evaporate the chemical liquid.

  The chemical vapor, together with the air introduced from the communication hole 227, rises in the inner cover 6 constituting a part of the ventilation path R, and is provided on the lid body 4 and the lid body 4 constituting a part of the ventilation path R. It is guided to the evaporation tower 46 and evaporated from the evaporation hole 41 into the room.

  On the other hand, chemicals may adhere to the back of the main unit case due to prolonged use, or the heating evaporator may be accidentally overturned, and further, the chemical may adhere to the back of the main unit case with the evaporation port closed. Even if it exists, it adheres to the inner cover 6 which comprises the ventilation path R, the lower surface of the cover body 4, or the outer surface of the main body upper part 22, and the condensed chemical | medical solution flows down along the outer surface of the inner cover 6 and the main body upper part 22, and communicates It flows out of the main body 2 from the hole 227.

  At this time, since the air passage R has a watertight structure, the condensed chemical liquid does not reach the inner surface of the case body 3, and even if an acrylic resin is used, the chemical liquid does not adhere to the back surface, and the main body case No corrosion or cracking occurs.

  Further, the chemical solution flows down along the outer surfaces of the inner cover 6 and the main body upper portion 22, but the locking protrusion 238 provided in the lower body portion 23 and the locking groove 61 provided in the lower end of the inner cover 6 are uneven. Since it is a coupling | bonding, the liquid leak from this coupling | bond part is prevented reliably.

  Moreover, since the case body is divided | segmented into the some division | segmentation case body, even if a chemical | medical solution reaches the case body inner surface, a chemical | medical solution can be escaped from a joint.

  Furthermore, by molding the case body with an acrylic resin, it is more transparent and glossy than when a polypropylene resin is used, and has a high-class feeling.

  In the present embodiment, the example in which the air passage is constituted by a separate lid and the inner cover has been described. However, the air passage may be integrated with the lid and the inner cover, and the inner cover is integrated with the main body. There may be.

  According to the heating evaporator of this embodiment, there is a high-class feeling, and a heating evaporator that is excellent in aesthetics by preventing contamination of the main body case by a chemical solution is realized.
