2. Description of the Related Art A pest control machine of this type is, for example, an actual Kaihei 2
It is known in Japanese Patent Publication No. 142171 and Japanese Utility Model Laid-Open No. 5-85277. There, a large number of drug plates are housed side by side in a vertical position in the main body case, the outside air is sucked in by a blower fan arranged above this drug plate, and this drug is evaporated by passing this outside air between the drug plates. The gas containing the insecticidal component is discharged into the room from the discharge port provided in the lower front part of the main body case.

[0003]

However, since the above-mentioned medicine plates arranged in a vertical posture are likely to be curved and deformed into a dogleg shape with the passage of time, they come into contact with an adjacent medicine plate to block the gas flow path. However, there is a problem in that the ability to evaporate the drug and to flow out is reduced. The present invention has been made in view of such circumstances, and it is an object of the present invention to prevent the drug plate from being deformed with time and to improve the efficiency of evaporative outflow of the drug. Another object of the present invention is to simplify periodical replacement of the medicine plate.

[0004]

The pest control machine of the present invention comprises:
A partition plate is provided inside the portable body case, and a blower drive chamber and a drug chamber are formed above and below this partition plate, and a vent port that connects the blower drive chamber and the drug chamber is provided in the partition plate. That the

In the blower drive chamber, an air inlet is provided on the front side of the air blower, and the blower blows outside air from the air inlet and blows it into the medicine chamber through the air vent,
Built-in a heater arranged between the blower and the ventilation port,

In the drug chamber, the back side of the drug chamber is closed by a back cover so as to be openable and closable, a discharge port is provided on the front side, and the carrier is impregnated with a transpiration insecticide on the inner surface of the back cover. The drug shelf supporting the plate is integrally attached,

In the medicine shelf, a plurality of shed shelves in which shelter wire rods are arranged in a horizontal direction at a predetermined pitch are provided in a plurality of upper and lower stages, and a shelf bottom is provided below the lowest shed shelves so that they are adjacent to each other in the lateral direction. It is characterized in that the drug plate is vertically inserted into the gap between the coiled wires so as to be vertically removable.

[0008]

The hot air is blown between the medicine plates by the blower and the heater, so that the medicine can be effectively evaporated.

Since the drug plate is supported at several points in the vertical direction by a plurality of shelves, it can be prevented from being bent and deformed with time and can be held in a vertical posture until it is used up. Therefore, it is possible to always secure a gas distribution path having a predetermined width between the medicine plates.

The drug plate can be easily replaced by opening the back cover together with the drug rack.

An intake port 6 is opened in the upper part of the front wall of the main body case 1 corresponding to the front side of the blower drive chamber 3, and an air filter 7 is attached to the intake port 6. The back side of the blower drive chamber 3 is closed by an inspection lid 8 so that it can be opened and closed.

The blower drive chamber 3 is further divided into left and right by a vertical partition plate 9, and a blower fan 10 for taking in outside air from an intake port 6 and a blower 12 composed of this drive motor 11 are provided in one of the left and right chambers. The mounting base 13 and the mounting base 13 are arranged one above the other, and the control board, the timer backup power supply battery 13 and the like are housed in the other room, and the control panel 14 is fitted on the front side. The ventilation port 5 is provided below the mount 13. A wire mesh 14 is attached to the bottom side of the ventilation port 5 (see FIG. 5).

As shown in FIGS. 5 and 6, the mounting base 13 has heat radiating plates 16 made of ceramic or the like having fins 15 attached to the inner surfaces thereof, which are opposed to each other at a predetermined interval, and between the fins 15 of each heat radiating plate 16. A heating element (planar heater) 17 having a heater wire embedded in a ceramic body or the like in the center is contact-polymerized to transfer the heat of the heating element 17 to the heat radiating plate 16 and radiate from the surface of the heat radiating plate 16. The heating element 17 measures the temperature of the medicine chamber 4 by 17 ° at a temperature set by a temperature sensor (not shown).

In the machine constructed as described above, when the power switch 33 on the control panel 14 is turned on to drive the blower 12, the outside air is blown from the intake port 6 into the blow drive chamber 3
The air is taken in and heated by the mounting base 13 to become warm air, which is blown into the medicine chamber 4 from the ventilation port 5. The warm air blown into the medicine chamber 4 passes between the medicine plates 19 to evaporate the medicine and discharge the gas containing the insecticidal component from the discharge port 20 to the outside.

In this use, it is possible to start the operation for a predetermined time every day and for an arbitrary time by a timer setting and to automatically stop the operation after the predetermined time has elapsed.

Further, even when the indoor temperature is lowered at night or in winter during the operation, the drive motor 11 can be operated with the heating element 17 being turned on and off by the operation of the temperature sensor.

[0021]

EFFECTS OF THE INVENTION According to the present invention, ventilation of the medicine plate is not obstructed by the shelter shelf, and the medicine plate in a vertical posture is curved and deformed over time due to multipoint support by the shelves having a plurality of stages. Since it is possible to prevent the gas flow path having a predetermined width between the medicine plates, the gas from which the insecticide has evaporated can be surely discharged from the discharge port.

By opening the case back together with the medicine rack, the medicine plate can be easily replaced.
