Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vaporizing apparatus for vaporizing a chemical for the purpose of controlling pests, deodorizing aroma, etc., and for spreading the chemical widely using a fan.

[0002]

2. Description of the Related Art An evaporating apparatus is an apparatus for evaporating a chemical into a space to be treated to control pests and deodorize aroma. This is driven continuously or intermittently according to the purpose of use. Electric mosquito traps and electric deodorizers fall under this category. In some cases, the drug evaporates at room temperature without heating the drug.

[0003] When pest control and aroma deodorization are carried out by evaporating a drug, there is a close relationship between the space and the amount of the evaporating drug, and the drug evaporates in an amount more than necessary to obtain an effective effect. There is a need. In general, a transpiration device is used in a space having a floor area of 26.4 m ² (8 tsubo) or less. I'm doing it.

[0004]

When the floor area of the space to be treated becomes 26.4 m ² or more, sufficient diffusion cannot be achieved only by the thermal diffusion effect of the heated evaporant. In general, when the volume of the processing space increases, the amount of chemicals to be evaporated needs to be increased accordingly.

[0005] However, if the increased vaporized chemicals are not sufficiently diffused, a portion of the processing space where the vaporized chemicals are dense,
Thin areas are created, leading to bias in drug effects and concerns about safety.

[0006] It is common sense to use a fan to blow the chemicals evaporated in a large processing space sufficiently, but when the evaporator and the fan are combined, the heat generated by the fan is blown by the fan. In addition, the temperature of the drug-evaporated portion is lowered due to cooling, and the ability to evaporate the drug is reduced (for example, Japanese Utility Model Application Laid-Open No. 63-20784 and Japanese Patent Application Laid-Open No. 61-11646).

When the evaporator is of a liquid heating type, the core impregnated with the chemical is heated mainly by the heat transfer of air.
If the air around the core is cooled by the air blown by the fan, the ability of the core to evaporate from the core is reduced, and the expected effect cannot be obtained.

As the processing space becomes larger, a more powerful fan is required. However, the heat generating portion and the chemical evaporating portion of the evaporator are cooled down, and the temperature is greatly reduced, making it difficult to evaporate the required amount of the chemical.

[0009] A region in which the temperature drop in the evaporator due to the air blow and the ability to evaporate the drug decreases, and the requirement that the drug must be sufficiently diffused by the air blow to simultaneously satisfy the contradictory conditions. Has already been studied and an application has been filed in JP-A-11-127756.

[0010] The present invention is further devised by the present inventors to prepare a condition that may simultaneously satisfy the above contradictory conditions besides the above-mentioned application technology, and to devise an even more useful structure. The vaporized medicine can be uniformly diffused even in a large processing space without impairing the vaporization capacity of the fan, and the vaporized medicine vaporized from the chemical vaporization part is not sucked from the suction side of the fan, so that the fan is not vaporized. It is an object of the present invention to provide a transpiration device that is prevented from being contaminated by chemicals.

[0011]

As a result of researches and experiments conducted by the present inventors, the above-mentioned satisfactorily satisfying the conflicting conditions of the reduction of the ability of the evaporator to evaporate the medicine and the necessity of the diffusion of the medicine by the blast. It was found that the region exists not only in the vicinity of the fan airflow but also in a part deviating from the vicinity of the airflow depending on conditions.

That is, the vicinity of the fan main body deviating from the vicinity of the air flow of the fan, more specifically, the left and right and vertical portions of the fan main body.

Normally, if there is a medicine evaporating port of the evaporator in this part, the evaporating medicine may be sucked from the suction side of the fan. When the vaporized medicine is sucked from the suction side,
It is not preferable because the chemicals adhere to the blades of the fan and the amount of the vaporized chemicals is impaired, and the blades of the fan become dirty.

Therefore, in the present invention, the evaporator is disposed so that the evaporator port is opposed within a range opposing the side surface extending from left and right to the lower side of the fan body, and the evaporator is provided between the suction side of the fan and the evaporator. A partition was provided to prevent direct suction of the vaporized drug from the suction side of the fan.

Thus, the above-mentioned conflicting conditions can be satisfied at the same time, and the evaporating agent is discharged from the evaporating device without coming into contact with any part of the fan. The fact that the evaporative agent does not contact any part of the fan means that the evaporator fan is not contaminated with the evaporative agent.

[Test Examples 1 to 3] In Test Examples 1 to 3, this state was visualized using smoke and observed. Each test example will be described with reference to FIGS. In the drawings, reference numeral 1 denotes a fan main body of the fan, and reference numeral 2 denotes a partition wall extending from the lower end of the fan main body 1 to the suction upstream side to separate the suction side of the fan main body from the periphery including the lower side. And 3, 4 in the figure
Are the upper and lower edges of the blown airflow of the fan.

Test Example 1 was performed when the smoke source was placed at a position 2 cm below the fan body 1 and at three positions a, b, and c shifted in the direction of air flow of the fan body 1. ,
Similarly, when a smoke source was placed at a, b, and c 5 cm below the fan body 1, the test example 3
The locus of smoke from each of the smoke sources when the smoke sources are placed at positions a, b, and c of 0 cm is shown. The positions of a, b, and c of the smoke source are as follows: a is the same position as the blow-out end of the fan body 1, b is 15 mm from this, and c is a position horizontally separated 30 mm from the suction side.

Observing the trend of smoke in each of the test examples, it is found that 2c is located just below the fan body 1 in the case of test examples 1 and 2.
m, the smoke from each of the smoke sources a, b, and c placed at a position of 5 cm rises while drawing a gentle curve in the blowout direction of the fan, and does not reach the fan body 1 located directly above.
It was entrained by the blowing airflow. The smoke source a of Test Example 3
When b and c were placed at a position of 10 cm directly below the fan main body 1, most of the smoke was blown out and entrained by the airflow, but this smoke fluctuated on the way and a phenomenon of branching was observed.

Considering the results of the above Test Examples 1, 2 and 3, the smoke sources a, b and c disposed directly below the fan body 1 are shown.
As shown in Test Example 3, a distance of 10 cm from the fan main body 1 is too far for smoke from the fan to be stably sucked into the blowing airflow without swinging or branching. As a result of the test accompanying Test Example 3, it was found that the distance from the fan main body 1 to which the smoke was stably sucked into the blowing airflow was up to 9 cm.

Further, as shown in Test Example 1, if the smoke source is separated from the fan body 1 by 2 cm, the smoke is sufficiently stably sucked into the blowing airflow. Then, as a result of an accompanying test of Test Example 1, the distance from the fan body 1 was 1 cm.
Smoke was stably sucked into the blowing airflow even when the
A phenomenon was observed in which a part of the smoke from a position closer to a centimeter came in contact with the lower surface of the fan body 1.

From these facts, it has been found that the object of the present invention can be achieved when the distance between the fan body 1 and the evaporation port of the evaporator is 1 cm or more and 9 cm or less. In each of the above test examples, the smoke from each of the smoke sources a, b,
It was not blocked by the fan and turned to the suction side of the fan, so that this smoke was not sucked into the fan.

[Test Example 4] Next, the evaporator was placed directly below the fan body 1 and the position of the evaporator was determined by the above Tests 1 to 4.
In Test Example 4, the transpiration core temperatures at a, b, and c in FIG. 3 and at a plurality of positions vertically separated from the fan main body 1 at the respective positions were examined. Table 1 shows the results.
Indicated by The specifications of the fan used in this test are
The size is 60 × 60 mm, the thickness of the fan body (axial length) is 30 mm, the wind speed is 6 m / sec, and the specification of the evaporator uses the evaporator 8 shown in FIG.
The test room was a room temperature of 25 ° C., no wind, and the thermometer used was a thermocouple surface thermometer (HL-300, Anritsu meter).

[0023]

[Table 1]

As a result of Test Example 4, the temperature of the transpiration core of the transpirator was almost the same as the value measured in the absence of wind.
It was confirmed that there was no fear of being lost by the blown airflow by the fan.

[Test Example 5] In Test Example 5, how the effect in Test Example 4 described above changes with the wind speed of the fan was examined. Table 2 shows the results. In this case, the position of the transpiration port was 10 mm below the fan main body, and the horizontal position was 15 mm (position b) from the end on the blowing side. The evaporator and thermometer used at this time are the same as those in Test Example 4. The anemometer is a Tr-type micro anemometer (Rion)
Was used.

[0026]

[Table 2]

From the results of Test Example 5, it was found that the fan having a wind speed of less than 1 m / s did not have sufficient power to blow out the smoke from the transpiration port into the air flow, and the smoke reached the fan body. This means that the fan is contaminated with the transpirant. At this wind speed, if the transpiration port is located right beside the fan main body, the smoke will rise as it is without being sucked into the blown airflow. On the other hand, when the wind speed is 1
When it exceeded 0 m / sec, a decrease in the temperature of the evaporation core of the evaporator was observed.

From the test example 5, the wind speed of the fan was 1 m
/ Sec or more and 10 m / sec or less.
