Fig. 5 is a schematic view showing an evapotranation state of a drug caused by a heating ejector according to the first embodiment of the present invention.

As shown in Fig. 5, the evaporating evaporators 1, 1A, and 1B are heated to elevate the liquid medicine 106 vaporized from the liquid-absorbent core 105 by the heater 6 which generates heat, and can also warm the air in the evaporating space 17.

The chemical solution 106 vaporized by the wick 105 is divided into: the central evapotranspiration port 19 is discharged to the outside of the heating eliminator 1, 1A, 1B, and is discharged from the outer evapotranspiration port 3d to the heating via the guiding portions 7, 7A. The outside of the evapotranzer 1, 1A, 1B.

On the other hand, the air of the evapotranspiration space 17 which is heated is the flow of air generated in the evapotranspiration space 17 (so-called upflow, solid arrow F in Fig. 5). The ascending flow F is because the intake port 13b is open to the inside of the side wall 3a than the wick 105, and therefore flows into the evapotranspiration space 17 from the inside of the side wall 3a from the intake port 13b. The heater 6 is heated and rises, and is discharged to the outside of the heating evaluators 1, 1A, 1B from all of the central evapotranes 19 or the outer evapotranspiration ports 3d.

In addition, the upward flow F is discharged from the flexure portion 3c of the heating evaluators 1, 1A, 1B as the chemical liquid 106 (solid arrow f in Fig. 5) that has been vaporized in the evapotranspiration space 17 is completely vaporized. The projection is spread above the heating evaporators 1, 1A, 1B (the two-point chain line A in Fig. 5), and is also located on the side (width direction), and rises on one side. Further, if the vaporized chemical liquid 106 is liquefied inside the lid portion 3 before reaching the outer peripheral vapor diffusion port 3d, the total amount of the chemical liquid 106 to be diffused is reduced, so that the chemical liquid 106 is also discharged from the central vapor deposition port 19. .

In the heating ejector 1, 1A, and 1B of the present embodiment, not only the vaporized chemical solution 106 can be diffused to the upper side of the heating eliminators 1, 1A, and 1B, It is also possible to diffuse toward the side, so that the directivity of the chemical liquid 106 standing upright in the direction of the heating evaporators 1, 1A, 1B is radially dispersed, and the adhesion of the chemical liquid 106 to the roof of the house can be suppressed. The upper portion of the evaporator 1, 1A, 1B is heated. Further, the chemical liquid 106 which is projected to the side above the heating evaporators 1, 1A, and 1B is diffused to a wider range and rapidly spreads into the entire house.

Specifically, the applicant of the present invention conducted the experiment by using the heating evapotraner 1 (Fig. 1) as the first embodiment and the heating evapotranzer 1A (Fig. 3) as the second embodiment. The heating evapotranor 1 or the heating evapotranator 1A was placed in the center of the floor of a room having a floor area of about six tatami (length 3.2 m, width 2.8 m) and a roof height of about 2.5 m, and the chemical liquid 106 was evaporated for about 2 hours. On the wall surface from the height of the floor of 2.2 m, the glass plate is placed on the roof surface of the room above the heating evapotranator 1 and recovered at 10 minutes, 20 minutes, 30 minutes, 60 minutes and 120 minutes after the start of evapotranspiration. The glass plate was measured and the amount of the drug attached was measured. Moreover, the heating evacuator which plugged the outer side vapor-distribution opening 3d of the heating ejector 1A and only the center vent port 19 was opened as a conventional example, and the experiment was performed under the same conditions, and the adhesion amount of the drug was measured. Further, the drug is a dextrin contained in the drug solution 106.

The measurement results are shown in Tables 1 and 2. Table 1 shows the measurement results of the wall surface of the living room, and Table 2 shows the measurement results of the roof surface.

The linear approximation was obtained from the results of Table 1 (the amount of dextrin adhesion per evapotranspiration time on the wall surface), and the diffusion rate of the drug was calculated from the inclination of the linear approximation, and the diffusion rate of the drug of the conventional heating ejector was determined. It is the relative speed of diffusion at 1 o'clock. The diffusion rate relative ratio is about 30% improvement in Example 1, and about 15% improvement in Example 2, and the diffusion volume of the drug is about 130% increase in Example 1, and in the embodiment. 2 has an increase of about 60%.

On the one hand, the results of Table 2 (the amount of agent attached to the roof surface) are about 30% lower in Example 1 and about 10% lower in Example 2 than in the conventional heating evapotranspiration, but at the beginning of evapotranspiration. The drug adhered to the early 10 minutes, and the present embodiment did not reduce the ascending air current. In other words, in the heating ejector 1 and 1A of the present embodiment, the strength of the ascending air current of the conventional heating ejector is hardly changed, and the medicine can be diffused radially, so that the medicine can be more rapidly extended to each of the living rooms. corner.

In the heating ejector 1 and 1A of the present embodiment, by having the outer peripheral vent 3d, the medicine 106 can be more rapidly extended to each corner of the living room as compared with the conventional example. In particular, the heating evapotranator 1 is The guiding portion 7 of the convex curved surface downward can also expand the medicament 106 more rapidly to each corner of the living room than the heating ejector 1A. On the other hand, the heating ejector 1A has a flat guiding portion 7, and the medicine 106 can be expanded more rapidly to each corner of the living room than the conventional heating ejector.

Further, the heating ejector 1, 1A, and 1B of the present embodiment guides the vaporized chemical liquid 106 to the outer peripheral vent 3d by the guide portion 7 having a curved shape or the guide portion 7A having a planar shape. Therefore, the diffusion speed of the chemical liquid 106 can be increased by a simple configuration without a supplemental device such as a fan.

The circular opening 19a having a small inner diameter is directly above the wick 105 of the liquid container 101 installed in the holding portion 5; the plurality of small petal-like openings 19d are extended in an elliptical shape surrounding the circular opening 19a. The petal-shaped opening 19c is a petal-like shape extending around the small petal-shaped opening 19d and extending approximately in an elliptical shape. Further, the central evapotranization port 19C is a chemical liquid which is vaporized in a wide range in order to easily diffuse, and the opening area is smaller than the outer peripheral venting port 3e. The top wall 3b is provided on the side of the evapotranspiration space 17 (that is, on the inner surface side of the top wall 3b) with an annular evaporation cylinder surrounding the central venting port 19C (more specifically, the circular opening 19a and the small petal-shaped opening 19d). 21C. The evaporation cylinder 21C guides the chemical liquid 106 vaporized from the wick 105 to the central vent port 19C (more specifically, the circular opening 19a and the small petal-shaped opening 19d), and will fail to pass through the central venting port 19C. On the other hand, a part of the chemical liquid 106 overflowing from the lower end of the evaporation drum 21C is distributed to the guide portion 7C (and, further, the outer peripheral vapor diffusion port 3e). By properly adjusting the opening area of the peripheral effluent opening 3e and the central venting port 19C and the height of the squirting cylinder 21C, the amount of the vaporized chemical liquid 106 can be controlled, and the squirting cylinder 21C can be abolished in response to the desired distribution amount. can.

The projection above the heating ejector 1C (the two-point chain line A in Fig. 8) is also located on the side (width direction) and rises on one side. Further, since the vaporized chemical liquid 106 is liquefied inside the lid portion 3C before reaching the outer peripheral vapor diffusion port 3e, the total amount of the chemical liquid 106 to be diffused is reduced, so that the chemical liquid 106 is also discharged from the central vapor deposition port 19C. .

In the heating ejector 1C of the present embodiment, not only the vaporized chemical solution 106 can be diffused to the upper side of the heating ejector 1C but also diffused toward the side, the medicinal liquid 106 can be erected in the upper direction of the heating evapotranator 1C. The directivity of the liquid 106 is radially dispersed, and it is possible to suppress the chemical liquid 106 from adhering to the portion directly above the heating ejector 1C on the roof of the house. Further, the chemical liquid 106 which is projected to the side further than the upper side of the heating ejector 1C is diffused to a wider range and rapidly spreads into the entire house.

Specifically, the applicant of the present invention conducted the experiment by using the heating evapotranspiration 1C as Example 3. The heating evapotranzer 1C was placed in the center of the floor of the living room having a floor area of about six tatami (length 3.2 m, width 2.8 m) and a roof height of about 2.5 m, and the liquid medicine 106 was evaporated for about 2 hours. On the wall surface from the floor height of 2.2 m, a glass plate is placed on the roof surface of the room above the heating evapotranator 1C, and is recovered at 10 minutes, 20 minutes, 30 minutes, 60 minutes, and 120 minutes after the start of evapotranspiration. The glass plate was measured and the amount of the drug attached was measured. Further, a heating evapotent that plugs the outer evapotranspiration 3d of the heating evapotranzer 1A and opens only the central venting port 19 as a conventional example is tested under the same conditions to measure the amount of the drug attached. . Further, the drug is a dextrin contained in the drug solution 106.

The measurement results are shown in Tables 3 and 4. Table 3 shows the measurement results of the wall surface of the living room, and Table 4 shows the measurement results of the roof surface.

The linear approximation was obtained from the results of Table 3 (the amount of dextrin adhesion per evapotranspiration time on the wall surface), and the diffusion rate of the drug was calculated from the inclination of the linear approximation, and the diffusion rate of the drug of the conventional heating ejector was determined. It is the relative speed of diffusion at 1 o'clock. The diffusion rate relative ratio was improved by about 10% in Example 3, and the diffusion volume of the agent was increased by about 30% in Example 3.

On the one hand, the result of Table 4 (the amount of the drug adhering to the roof surface) was reduced by about 5% in Example 3 as compared with the conventional heating evapotranspiration, but the drug was adhered to the early stage of the evapotranspiration for 10 minutes. According to this embodiment, the case where the upward airflow is not reduced is not obtained. In other words, in the heating ejector 1C of the present embodiment, the strength of the ascending air current of the conventional heating ejector is hardly changed, and the medicine can be radially diffused, so that the medicine can be further Quickly expand to all corners of the living room.

In the heating ejector 1C of the present embodiment, by having the outer peripheral vent 3e, the medicine 106 can be more rapidly extended to each corner of the living room as compared with the conventional example.

[Third embodiment]

The third embodiment of the heating ejector according to the present invention will be described with reference to Figs. 9 to 11 .

Fig. 9 is a perspective view showing a heating ejector according to a third embodiment of the present invention.

Fig. 10 is a longitudinal sectional view showing a heating ejector according to a third embodiment of the present invention in X-X of Fig. 9.

In the heating ejector 1D of the first embodiment, the same components as those of the heating ejector 1 of the first embodiment are denoted by the same reference numerals, and the description thereof will not be repeated.

As shown in Fig. 9 and Fig. 10, the heating ejector 1D of the present embodiment is combined with the liquid container 101, and the chemical liquid 106 is evaded. The heating ejector 1D includes a lid portion 3D, a holding portion 5, a heater 6, and a guide portion 7D. The lid portion 3D covers the upper portion of the liquid container 101. The holding portion 5 holds the liquid container 101 detachably from the inside of the lid portion 3D. The heater 6 is housed in the lid portion 3D and is wicked. 105 is freely heated; the guide portion 7D guides the chemical solution 106 vaporized by the wick 105 to the outer peripheral vent 3g by heating of the heater 6. The cover portion 3D has a curvature between the side wall 3a and the top wall 3b. The curved portion 3h has a peripheral effluent opening 3g opened to the bent portion 3h, and a central venting port 19D which is located above the wick 105 and opens to the top wall 3b.

The lid portion 3D is a molded product of a synthetic resin, and has a bottomed cylindrical outer shape that is opened below. The lid portion 3D covers the evapotranspiration space 17 above the holding portion 5. The side wall 3a corresponding to the side surface of the cylindrical shape is a wall that is vertically erected with respect to the mounting surface of the heating ejector 1D. The top wall 3b corresponding to the bottom surface of the cylindrical shape is a wall that extends approximately horizontally with respect to the mounting surface of the heating ejector 1D. The side wall 3a and the top wall 3b are connected by a bent portion 3h bent at a right angle. The bent portion 3h is a portion of the entire circumference of the upper edge of the side wall 3a and the periphery of the top wall 3b. Further, the shape of the lid portion 3D is not limited to a cylindrical shape, and may be in various forms such as a square shape or a polygonal shape.

The outer peripheral vapor diffusion port 3g is a through port that communicates inside and outside the lid portion 3D. Further, the outer peripheral vent 3g is a slit-shaped open group extending along the bent portion 3h. Therefore, even if the entire curved portion 3h is formed over the entire circumference, the appearance can be made without damaging the appearance. Increase the opening area. The outer peripheral vent 3g is a large annular portion which is located at the top of the side wall 3a by the step difference wall 3i, and a lower open group portion which is located above the small annular portion of the outer peripheral edge portion of the top wall 3b. The rib 26 connects the side wall 3a, the step difference wall 3i, and the top wall 3b across the outer peripheral vapor diffusion port 3g.

Further, when the foreign matter does not easily infiltrate from the upper side of the outer peripheral vapor diffusion port 3g, when the lid portion 3D is viewed from above, it is preferable that the evapotranspiration space 17 is not visible from the outer peripheral vapor diffusion port 3g. That is, the outer evapotranspiration 3g, in a bird's eye view It is preferable to see that it is hidden in the top wall 3b and the bent portion 3h. Specifically, the lid portion 3D is provided with a step portion 3j that is recessed downward on the inner side of the stepped wall 3i and the inner peripheral side of the upper end of the side wall 3a and extends inward, and is located inside the respective stages 3j. The outer periphery of the upper wall, that is, the outer periphery of the top wall 3b and the outer periphery of the step wall 3i, and the inner periphery of each of the stage portions 3j are adjacent or coincident in the vertical direction. In addition, as for the slit (so-called horizontal slit) in which the outer peripheral vent 3g is oriented toward the side, the slit (the so-called vertical slit) extending radially from the center in the first embodiment, for example, It is preferable to make the amount of diffusion on the opposite side larger (refer to Table 1, Table 2, Table 5, and Table 6).

Further, the outer peripheral vapor diffusion port 3g may be one opening, or may be arranged in a plurality of openings of three or more.

The central evapotranspiration port 19D has a circular opening 19a having a small inner diameter and a plurality of curved openings 19e. The circular opening 19a having a small inner diameter is directly above the wick 105 of the liquid container 101 installed in the holding portion 5; the plurality of curved openings 19e are connected to the circular opening 19a and extend radially The shape of the water droplets to the outside of the radial direction. When a sharp-shaped opening (in the front end portion on the center side of the center) of the wide and narrow water droplet shape is present in the center portion directly above the wick 105, the wick 101 is vaporized to the tip portion and rises. Since the chemical liquid 106 is easily condensed, the shape of the opening portion which is not sharp at the center portion is preferable, and the central venting port 19D is connected to the circular opening 19a and the curved opening 19e. Further, the central evapotranization port 19D is a chemical liquid which is vaporized in a wide range in order to easily diffuse, and the opening area is smaller than the outer peripheral venting port 3g. The top wall 3b is on the side of the evapotranspiration space 17 (ie, the top wall) The inner surface side of 3b) is provided with an annular evacuation cylinder 21D that surrounds the central vent port 19D (more specifically, the circular opening 19a and the curved opening 19e). The evaporation cylinder 21D guides the chemical liquid 106 vaporized from the wick 105 to the central vent port 19D (more specifically, the circular opening 19a and the curved opening 19e), and will fail to pass through the central vent port 19D and A portion of the chemical liquid 106 overflowing from the lower end of the evaporation drum 21D is partially distributed to the guide portion 7D (and, further, the outer peripheral vapor diffusion port 3g). By properly adjusting the opening area of the peripheral effluent opening 3g and the central venting port 19D and the height of the squirting cylinder 21D, the amount of the vaporized chemical liquid 106 can be controlled, and the sterilizing cylinder 21D can be abolished in response to the desired distribution amount. can. Further, the shape of the outer peripheral vapor diffusion port 3g and the central vaporization opening 19D is not limited to the above-described shape, and may be various shapes.

The guide portion 7D guides the vapor of the chemical liquid 106 overflowing from the lower end of the evacuation cylinder 21D surrounding the central vent port 19D toward the outer peripheral vent 3g.

In the heating ejector 1D configured as described above, when the liquid container 101 in which the chemical liquid 106 remains is fixed to the holder base 13, the medicinal liquid 106 can be evacuable. Then, the ejector 1D is heated, and when the power switch 9 is turned on, the heater 6 is heated and the wick 105 is heated.

Fig. 11 is a schematic view showing an evapotranspiration state of a drug caused by a heating ejector according to a third embodiment of the present invention.

As shown in Fig. 11, the ejector 1D is heated to promote the liquid medicine 106 vaporized from the wick 105 by the heater 6 which generates heat, and to warm the air in the evapotranspiration space 17.

The liquid medicine 106 that is vaporized from the wick 105 is divided into: from the center The evapotranspiration port 19D is discharged to the outside of the heating ejector 1D, and is discharged to the outside of the heating eliminator 1D via the guiding portion 7D and discharged from the outer peripheral venting port 3g.

On the other hand, the air of the evapotranspiration space 17 which is heated is the flow of air generated in the evapotranspiration space 17 (so-called upflow, solid arrow F in Fig. 11). The ascending flow F is because the intake port 13b is opened inside the side wall 3a than the wick 105, and therefore flows into the evapotranspiration space 17 from the intake port 13b along the inner side of the side wall 3a, and is heated by the suction port 13b. The heater 6 is raised while being warmed, and is discharged from the outer peripheral vent 3g to the outside of the heating eliminator 1D from the central evapotranspiration port 19D.

Further, the upward flow F is a chemical liquid 106 (solid arrow f in the eleventh diagram) which is vaporized in the evapotranspiration space 17, and is completely discharged from the flexure portion 3h of the heating ejector 1D, and is diffused to the ratio. The projection above the heating ejector 1D (the two-point chain line A in Fig. 11) is also located on the side (width direction) and rises on one side. Further, since the vaporized chemical liquid 106 is liquefied inside the lid portion 3D before reaching the outer peripheral vapor diffusion port 3g, the total amount of the chemical liquid 106 to be diffused is reduced. Therefore, the chemical liquid 106 is also removed from the central vapor deposition port 19D. Spit out.

In the heating ejector 1D of the present embodiment, not only the vaporized chemical liquid 106 can be diffused to the upper side of the heating ejector 1D but also diffused toward the side, so that it is erected in the upward direction of the heating ejector 1D. The directivity of the chemical liquid 106 is radially dispersed, and it is possible to suppress the chemical liquid 106 from adhering to the portion directly above the heating ejector 1D on the roof of the house. Further, the chemical liquid 106 which is projected toward the side further than the upper side of the heating ejector 1D is diffused to a wider range and rapidly spreads into the entire house.

Specifically, the applicant of the present invention uses the heating evapotranator 1D as an implementation. Example 4 was used for the experiment. The heating evapotranator 1D was placed in the center of the floor of the living room having a floor area of about six tatami (length 3.2 m, width 2.8 m) and the roof height was about 2.5 m, and the liquid medicine 106 was evaporated for about 2 hours. On the wall surface from the floor height of 2.2 m, the glass plate is placed on the roof surface of the room above the heating evapotranator 1D, and is recovered at 10 minutes, 20 minutes, 30 minutes, 60 minutes, and 120 minutes after the start of evapotranspiration. The glass plate was measured and the amount of the drug attached was measured. Moreover, the heating evacuator which plugged the outer side vapor-distribution opening 3d of the heating ejector 1A and only the center vent port 19 was opened as a conventional example, and the experiment was performed under the same conditions, and the adhesion amount of the drug was measured. Further, the drug is a dextrin contained in the drug solution 106.

The measurement results are shown in Tables 5 and 6. Table 5 shows the measurement results of the wall surface of the living room, and Table 6 shows the measurement results of the roof surface.

The linear approximation was obtained from the results of Table 5 (the amount of dextrin adhesion per evapotranspiration time on the wall surface), and the diffusion rate of the drug was calculated from the inclination of the linear approximation, and the diffusion rate of the drug of the conventional heating ejector was determined. It is the relative speed of diffusion at 1 o'clock. The diffusion speed relative ratio is approximately in Example 4. A 20% improvement, while the diffusion volume of the agent was about 80% higher in Example 4.

On the one hand, the result of Table 6 (the amount of the drug adhering to the roof surface) was reduced by about 20% in Example 4 as compared with the conventional heating eliminator, but the drug was adhered to the early stage of the evapotranspiration for 10 minutes. According to this embodiment, the case where the upward airflow is not reduced is not obtained. In other words, in the heating ejector 1D of the present embodiment, the strength of the ascending air current of the conventional heating ejector is hardly changed, and the medicine can be radially diffused, so that the medicine can be more rapidly expanded to every corner of the living room.

In the heating ejector 1D of the present embodiment, by having the outer peripheral venting port 3g, the medicine 106 can be more rapidly extended to each corner of the living room as compared with the conventional example.

Further, in the heating ejector 1D of the present embodiment, the outer peripheral vent 3g is slit-shaped along the flexure 3h, and even if the outer peripheral vent 3g is opened to the entire circumference of the flexure 3h, it is comprehensive. The opening area can be increased without impairing the appearance, because the chemical liquid 106 can be diffused more quickly to each corner of the living room than in the prior art. In addition, the outer peripheral vent 3g is a slit (so-called horizontal slit) that faces the side, and the slit (so-called vertical slit) that extends radially from the center in the first embodiment can be used as the opposite side. The amount of diffusion of the square is made more.

Further, in the heating ejector 1D of the present embodiment, by allowing the outer peripheral vent 3g to be concealed in the top wall 3b and the bent portion 3h in a plan view, it is possible to suppress entry of foreign matter from above the outer peripheral vent 3g.

Therefore, the heating evapotranes 1, 1A, 1B, 1C according to the present embodiment 1D, the chemical liquid 106 can be quickly spread to a wider range without the need for a supplemental device such as a blower.

The embodiments of the present invention have been described, but the embodiments are intended to be illustrative, and are not intended to limit the scope of the invention. The present invention may be embodied in other specific forms without departing from the spirit and scope of the invention.
