Are held by the insertion groove 52 and the gap 54.

Since the water supply groove 22 is provided with the water supply dropping ports 24 at appropriate intervals, the water supply amount becomes smaller and the water supply becomes slower as the distance from the connection position of the water supply hose 44 to the water supply groove 22 increases. There is a tendency. In order to supply water at the same amount over the entire circumference of the vaporization filter 19 at the same time, the diameter of the water supply dropping port 24 is increased as the distance from the connection position of the water supply hose to the water supply groove 22 increases.

The present embodiment is constructed as described above in detail, and the assembly sequence will be described next.

A fan motor 18 is mounted in the lower cylindrical body 9, and the fan motor 18 is provided with a sirocco fan 1 for blowing air.
5 is attached, and then the upper tubular body 8 is attached to the lower tubular body 9. A pump motor 43 is attached to the upper surface of the filter frame body 20, a water feed pump 42 is attached to the lower surface of the filter frame body 20, the water feed pump 42 is connected to the pump motor 43, and one end of the water feed pump 42 is connected to the water feed hose. 44 is passed through the through hole 45, and its tip is connected to the water supply groove 22. After that, the upper casing 2 is turned upside down and the filter frame body 20 is fixed in the lower tubular body 9 with screws. Subsequently, while inserting the upper edge of the vaporization filter 19 into the filter loose fitting groove 23 of the filter frame 20,
The upper edge of the air purification filter 51 is inserted into the insertion groove 52 of the filter frame body 20, and then the partition plate 25 below is attached to the filter frame body 20. As a result, the vaporization filter 19 and the air cleaning filter 51 described above are provided.
The lower end edges of the filters are fitted into the filter mounting groove 29 and the annular gap 54, respectively, and the filters 19 and 51 are fixed.

Finally, by placing the upper casing 2 on the lower casing 3, the upper casing 2 is joined to the lower casing by the connecting action of the protrusion 40 and the connecting hole 39 of the skirt 26 of the lower partition plate 25. It is fixed to 3 and the cold air fan is assembled.

When the power switch 48 is turned on and the changeover switch 49 is operated so as to cool the air, the fan motor 18 and the pump motor 43 are driven, the blow sirocco fan 15 and the water supply pump 42 are operated, and the water supply pump 42. As a result, the water in the water tank 5 is supplied to the water supply passage 22, and this water is supplied from the water supply passage 22 through the plurality of water supply dropping ports 24 over the entire upper end of the vaporization filter 19. As a result, the vaporization filter 19 has a substantially uniform water content over the entire area.

On the other hand, by the action of the sirocco fan 15 for blowing air and the cochlear-shaped air-breathing passage, suction and blowing action are generated, and the outside air is provided below the suction port 41 provided around the entire circumference of the upper casing 2. 9 and the air-cleaning filter 51, the sucked air is sucked from the entire area of the air-cleaning filter 51, and the air passing through the air-cleaning filter 51 is further vaporized by the vaporization filter 1
It is inhaled from all 9 areas. The air that has passed through the vaporization filter 19 passes through the small holes 21 of the filter frame body 20 through the communication port 16 and is sucked into the inside of the blower sirocco fan 15, and is subjected to the centrifugal action of the blower sirocco fan 15 to form a cochlear shape. It is blown out toward the outside from the outlet 17 through the wind passage. When the air passes through the water-containing vaporization filter 19, the vaporization is promoted and the heat of vaporization is used to cool the passing air. As a result, the cooling air having a temperature lower than that of the outside air is blown out from the outlet 17 and feels cool.

Water is always supplied in excess of the water content of the vaporization filter 19 so that the water is retained almost uniformly over the entire area of the vaporization filter 19, but excess water is always retained in the filter mounting groove. The water is collected in 29, and further water overflows from the drainage cutout groove 32 to the water receiving portion 30. The accumulated water disperses and permeates into the vaporization filter 19 due to the capillary action of the vaporization filter 19, and the water content of the vaporization filter 19 is made uniform over the entire area.

Since the outer periphery of the vaporization filter 19 is attached to the outer peripheral wall 53 of the filter attachment groove 29 at a distance, the vaporization filter 19 is transmitted to the outer periphery of the vaporization filter 19 and falls into the filter attachment groove 29 and scatters outward. Prevent that. The water collected in the water receiving portion 30 returns to the inside of the water tank 5 through the drainage port 33, but at this time, it travels through the water guiding rod 36 through the drainage port 33 and flows down into the water tank. Therefore, it does not fall from the drain port 33 with a clicking sound like raindrops.

Next, when the changeover switch 49 is switched to the air blowing side, the pump motor 43 is stopped and the water supply pump 42 is stopped. As a result, the vaporization filter 19
Is not supplied with water. Therefore, the vaporization filter 19
The water-containing state disappears and the vaporizing action does not occur. Therefore, the sucked air is not cooled, and the outside air is blown out from the blowout port 17 as it is, and only the air is blown.

By changing the strength changeover switch 50, the rotation speed of the fan motor changes,
The blowing strength of the sirocco fan 15 for blowing changes.

In this embodiment, since the vaporization filter 19 is formed in a cylindrical shape and the suction port 41 is provided all around the upper casing 2, the air passage area of the vaporization filter 19 can be increased. And it can be made small. Further, the outside air can be sucked uniformly over the entire area of the vaporization filter 19, the vaporization action can be promoted, and the cooling can be enhanced.

Further, since the suction port 41 is formed over the entire circumference of the cylindrical upper casing 2, even if it is placed at the corner of the room, it will not be blocked by the wall of the room. Therefore, the cold air fan can be used anywhere. Since the suction port 41 is sufficiently separated from the blowout port 17, the high-humidity air blown out from the blowout port 17 is not immediately sucked in, and the cooling efficiency is not lowered. Further, the lower partition plate 25 has an arc surface 25a.
Therefore, the outside air sucked through the suction port 41 is not exposed to the upper casing 2 and the air cleaning filter 51.
Flows almost linearly along the arc surface 25a between
The suction resistance can be made extremely small.

Since the vaporization filter 19 is located at a position higher than the water level of the water tank 5 which is full and is not immersed in the water tank 5, only the operation or stop of the water supply pump 42 is used to blow out cool air or blow air. It can be switched to only or easily switched.

Moreover, since the upper casing 2 side and the lower casing 3 side are each unit-shaped and the connecting means for both are simple, their assembly and disassembly are extremely easy. Further, cleaning of the vaporization filter 19, the water tank 5 and the like and replacement and replacement of the vaporization filter 19 and the like are extremely easy. Moreover, it has a simple structure and can be manufactured at low cost.

Next, FIG. 7 and FIG. 8 for the second embodiment.
The details will be described with reference to.

In this embodiment, the same symbols are used for the same parts as in the previous embodiment.

In order to supply water uniformly over the entire area of the vaporization filter 19, in the previous embodiment, the diameter of the water supply dropping port 24 is formed so as to become larger as the distance from the connection position of the water supply hose 44 to the water supply groove 22 increases. On the other hand, in the present embodiment, as shown in FIG. 7, the water absorbent material 55 made of cotton cloth or the like having good water absorbability is arranged in the filter loose fitting groove 23 over the entire circumference, and The upper surface of the vaporization filter 19 is bonded to the water absorbing material 55. A drain 56 is provided in the water supply groove 22 so that when a predetermined amount or more of water is supplied to the water supply groove 22, the water is drained from the drain 56 so that a constant amount of water is always retained in the water supply groove 22. .. Since the water absorption layer is formed between the feed water dropping port 24 and the vaporization filter 19, the water easily diffuses, and the dropping amount can be controlled by changing the density, so that the entire vaporization filter 19 can be made uniform. Can be supplied with water.

Further, as shown in FIG. 8, the upper end of the vaporization filter 19 is surrounded by a water-absorbing material 57 such as cellulose sponge, and when it absorbs water, it expands and acts as a packing material, and the vaporization filter 19 It is possible to make the water evenly distributed and to prevent excess water from flowing to the vaporization filter 19.

Next, the details of the third embodiment will be described with reference to FIGS. 9 to 14.

In the first embodiment, flocked open-cell urethane foam or sintered polyethylene material is used as the filter material of the vaporization filter 19, but since these are expensive, various studies have been conducted. As a result of stacking, an inexpensive filter material that has been developed and is excellent for a cold air fan will be described.

Since the vaporization filter 19 of the first embodiment is made of an open-cell urethane foam or a sintered polyethylene material, it takes a long time until the whole becomes a water-containing state, and after the water supply is stopped. However, the water content continued for a long time, and it tended to take a long time to switch from cold air to only air blowing, and it was expensive.

In this embodiment, as shown in FIGS. 9 and 10, a coarse woven fabric woven from fibers having excellent hydrophilicity such as cotton is wound in multiple layers to form a cylindrical shape. It is the vaporization filter 19 of the gauze. Especially, the gauze 58 is suitable.

When the cold gauze 58 is wound, a slight space is left between them so that they overlap with each other.

This makes it possible to improve the diffusion of water and retain water well. In addition, by increasing the density, it is possible to further improve the diffusion of water and increase the amount of water retained.

As a means for providing a space in the overlapping portion,
As shown in FIGS. 11 and 12, the upper end and the lower end of the gauze cloth 58 are bent and sewn 59, which is wound on a roll. Further, as shown in FIGS. 13 and 14, water-absorbing materials 60 such as prismatic cellulose sponge are attached to the upper and lower ends of the ginseng 58 and wound into a roll shape. This creates a gap in the upper and lower intermediate portions of the overlapping portion.

Since the cold gauze 58 has a relatively weak rigidity, it is preferable to attach a wire mesh formed in a cylindrical shape to the inside of the filter in order to prevent the filter from being deformed. Further, by impregnating, applying or spraying a resin on a woven cloth such as a gauze cloth 58, it is possible to strengthen the waist and prevent the filter from being deformed. In particular, there is no fear of buckling due to the weight of water even in the water-containing state, stable performance can be maintained for a long time, and it can be manufactured at a lower cost than using a wire mesh.

Further, the details of the fourth embodiment will be described with reference to FIG.

In the first embodiment, the water supply position of the water supply hose 44 is always constant with respect to the vaporization filter 19, whereas in the present embodiment, the water supply position of the water supply hose 44 with respect to the vaporization filter 19 is moved. I chose That is, in the present embodiment, the entire area of the vaporization filter 19 is faster,
In addition, the water is evenly added.

The same parts as those of the first embodiment will be described with reference to the same reference numerals.

As in the first embodiment, when water is pumped from the water tank 5 by the water supply pump 42 and is supplied to the vaporization filter 19 from one location, the water is vaporized by the vaporization filter 19.
Compared to the actual water consumption in order to spread the entire
A large amount of water must be supplied. Therefore, the vaporization filter 19 locally contains too much water and becomes clogged, the amount of air passing through is reduced, and the effect of cooling the air using the heat of vaporization cannot be maintained. In order to increase the amount of air passing through, the rotation speed of the sirocco fan 15 for blowing must be extremely increased. If the rotation speed is extremely increased, noise and the like increase sharply, which causes uncomfortable feeling to the people around. , Not usable.

On the contrary, when the amount of water supply is small, the amount of water dripped from the water supply drip openings 24 arranged at intervals over the entire circumference of the water supply groove 22 decreases as the distance from the water supply position increases. However, there is a tendency that the vaporization filter 19 is not evenly distributed over the entire area. However, the present embodiment is intended to prevent such a situation.

In this embodiment, the water supply pipe 61 is bent in an inverted U shape, and one end thereof is rotatably attached to the water supply hose 44.
The two are connected to each other and arranged so as to be rotatable around the axis X of the water supply groove 22, and the other end faces the water supply groove 22. The water supply pipe 61 is rotationally driven by a motor via an appropriate speed reducer, and supplies water at a constant speed over the entire circumference of the vaporization filter 19.

Although the water supply pipe 61 is rotated in this embodiment, the water supply pipe 61 may be fixed and the water supply groove 22 or the vaporization filter 19 may be rotated.

As is apparent from the above description, according to the present invention, a part of the lower surface of the water receiving portion 30 faces the drain port 33, and the lower surface of the water receiving portion 30 extends to the inside of the water tank 5. By providing the water guiding rod 36 extending downward,
The water collected in the water receiver 30 is discharged from the drain port 33 to the water tank 5.
Since it flows down to the surface of the water through the water guiding rod 36, a sound similar to a raindrop that drops from the drainage port 33 of the water receiving portion 30 to the surface of the water tank 5, that is, an unpleasant sound such as "pocha" is generated. It can be prevented, and discomfort to surrounding people can be eliminated.

Further, the structure is extremely simple and can be manufactured at low cost, so that the effect is extremely large.
