Description
- The present invention relates to an electric fan for blowing cool wind by utilizing vaporization heat of water contained in an evaporation filter.
- Although electric fans simply create a flow of air, the created flow of air blows off air heated on a surface of a person's human body, and thereby the person feels that the air from the electric fan is cool. However, since the electric fan basically does not have a function of decreasing the temperature of air, when the temperature of the air is too high, the person no longer feels that the air is cool.
- Therefore, an electric fan blowing cool wind by utilizing the vaporization heat of water to actively decrease the temperature of air, which is referred to as a cool wind fan, is used. More specifically, an evaporation filter is disposed in a path of air, and water is supplied to the evaporation filter. When the air passes through the evaporation filter containing water, the water contained in the evaporation filter is evaporated, and the air is deprived of the vaporization heat required for the vaporization of water, whereby the air is cooled.
- In this kind of the cool wind fan, the water supplied beyond the water-retaining capacity of the evaporation filter falls from the evaporation filter into a tank, which results in making unpleasant sound continuously. Patent Documents 1 and 2 disclose methods for preventing the unpleasant sound.

- Accordingly, an object of the present invention is to provide an electric fan capable of blowing cool wind efficiently even if the electric fan is a large flow rate fan having a large blade diameter.

The position of thesuction port 11 and the blowingport 12 on thehousing 10 can be suitably selected depending on the purpose. For example, thesuction port 11 can be formed on one side surface of thehousing 10, and the blowingport 12 can be formed on the opposed side surface of thehousing 10. However, in this case, warm air before cooling is continuously suctioned from thesuction port 11. In particular, for a large flow rate fan having a large blade diameter, the warm air is not sufficiently cooled and the warm air may still be blown from the blowingport 12. - Therefore, as shown in
FIG. 2 , it is important that thesuction port 11 and the blowingport 12 are formed on the same side surface of thehousing 10. In this way, a part of cool air blown from the blowingport 12 is suctioned from thesuction port 11 again, and thereby the air blown from the blowingport 12 becomes cooler. In particular, for a large flow rate fan having a large blade diameter, this configuration as described above is effective because it is difficult to cool the warm air instantaneously. Further, in terms of downsizing the electric fan, it is also important that the blowingport 12 is formed on the central part of one side surface of thehousing 10 and that thesuction port 11 is formed on the outer edge part of the blowingport 12, as shown inFIGS. 2 to 4 . The electric fan having this configuration can cool air effectively even if the electric fan is a large flow rate fan having a large blade diameter. - The
axial flow fan 20 is mounted in the middle of the flow channel between thesuction port 11 and the blowingport 12. Theaxial flow fan 20 is a fan for suctioning air from thesuction port 11 into thehousing 10 and for blowing the suctioned air from the blowingport 12. As described above, the structure of the electric fan according to the present invention is suitable for a large flow rate fan having a large blade diameter. More specifically, the blade diameter of the axial flow fan is preferably 20 to 50 inches, and is more preferably 24 to 36 inches. In addition, the flow rate of air is preferably 3500 to 35000 m3/h in operation, and is more preferably 5000 to 25000 m3/h. The motor for rotating theaxial flow fan 20 may be an internal motor in theaxial flow fan 20, or any other non-internal motor may be mounted to rotate theaxial flow fan 20 via a belt and a pulley. In the latter case, the rotational frequency of theaxial flow fan 20 can be adjusted by using a gear. - In the electric fan of the present invention, an
evaporation filter 30 is mounted for passing the air suctioned from thesuction port 11, as shown inFIG. 1 . Theevaporation filter 30 is mounted in a flow channel between thesuction port 11 and the blowingport 12. Theevaporation filter 30 is typically disposed upstream from theaxial flow fan 20. Theevaporation filter 30 may be made from a paper such as a corrugated cardboard, or from a plastic such as an open-cell polyurethane foam or a sintered polyethylene material. Since water is introduced to theevaporation filter 30, theevaporation filter 30 is preferably subjected to a treatment for improving the hydrophilicity, in particular when theevaporation filter 30 is made from a plastic. - In the electric fan of the present invention, by using a
water supplying system 40 having atank 41 and thewater supplying pipe 42, water is supplied (sprinkled) from awater sprinkler 42 a formed on awater supplying pipe 42 disposed over theevaporation filter 30 to theevaporation filter 30, as shown inFIG. 1 . That is, the water in thetank 41 is suctioned to thewater supplying pipe 42 with a pump (not shown) mounted in thetank 41, and is supplied from thewater sprinkler 42 a, which is formed over theevaporation filter 30, to theevaporation filter 30. In this way, water can be introduced to theevaporation filter 30 by supplying water from above of theevaporation filter 30. When the air suctioned from thesuction port 11 passes through theevaporation filter 30 containing water, the water contained in theevaporation filter 30 is evaporated, and the air is deprived of the vaporization heat required for the vaporization of water, whereby the air is cooled. Additionally, Ag ion ceramic balls can be put in abox 48 mounted in thetank 41 containing water, to suppress the generation of bacteria and to perform air cleaning function. By using a bactericidal lamp instead of the Ag ion ceramic balls, the generation of bacteria can be suppressed and air cleaning function can be performed as well. The position of the bactericidal lamp mounted may be in thetank 41 or may be in the middle of thewater supplying pipe 42. - In the electric fan of the present invention, a
pre-evaporation filter 35 for passing the air suctioned from thesuction port 11 is preferably mounted upstream from theevaporation filter 30, as shown inFIG. 1 . As for the mounted position of thepre-evaporation filter 35, thepre-evaporation filter 35 is mounted in the middle of the flow channel between thesuction port 11 and theevaporation filter 30. Thepre-evaporation filter 35 may be made from a paper such as a corrugated cardboard, or from a plastic such as an open-cell polyurethane foam or an sintered polyethylene material. Since water is introduced to thepre-evaporation filter 35, thepre-evaporation filter 35 is preferably subjected to a treatment for improving the hydrophilicity, in particular when thepre-evaporation filter 35 is made from a plastic. - Preferably, by using the
water supplying system 40, water is supplied (sprinkled) from awater sprinkler 42 b formed on awater supplying pipe 42 disposed over thepre-evaporation filter 35 to thepre-evaporation filter 35, as shown inFIG. 1 . That is, the water in thetank 41 is suctioned to thewater supplying pipe 42 with a pump (not shown) mounted in thetank 41, and is supplied from thewater sprinkler 42 b, which is formed over thepre-evaporation filter 35, to thepre-evaporation filter 35. In this way, water can be supplied from above of thepre-evaporation filter 35, and water can be introduced to thepre-evaporation filter 35. When the air suctioned from thesuction port 11 passes through thepre-evaporation filter 35 containing water, the water contained in thepre-evaporation filter 35 is evaporated, and the air is deprived of the vaporization heat required for the vaporization of water, whereby the air is cooled. - By mounting the
pre-evaporation filter 35 upstream from theevaporation filter 30 in this way, the air reaching theevaporation filter 30 can be previously cooled. In addition, theevaporation filter 30 is not exposed in thesuction port 11, and therefore theevaporation filter 30 is not heated, for example, by sunlight coming through thesuction port 11. As a result, the cooling efficiency of the air by theevaporation filter 30 can be improved. - The water supplied by using the
water supplying system 40 may be water at ordinary temperature, or water cooled with a chiller. For example, water can be cooled by adding animmersion chiller 45 in acooling unit 46 connected to thewater supplying pipe 42, as shown inFIG. 1 . In this case, by making a tube between thetank 41 and thecooling unit 46 thicker than the other part, the water tends to remain in thecooling unit 46, and thereby the cooling efficiency can be improved. Alternatively, by using a plurality ofchillers 45, immersion chillers can respectively be added in a plurality of areas formed by partitioning thetank 41. - As the
chiller 45, a relatively small chiller having an electric power for cooling of 1 to 10 kW can be used. Although heat is generated in thechiller 45, the heat can be dissipated, for example, by mounting aheat dissipating fan 16 a on the rear surface of thehousing 10 of the electric fan. - The water which is supplied to the
evaporation filter 30 or thepre-evaporation filter 35 but is not evaporated is preferably returned to thetank 41. In order to allow water exchange in thetank 41, a drain cock for draining off water in thetank 41 is preferably mounted on the lower part of thehousing 10, for example. - Water may be supplied to the
evaporation filter 30 and thepre-evaporation filter 35 by thewater supplying system 40 continuously or intermittently. Before stopping the electric fan, theevaporation filter 30 and thepre-evaporation filter 35 may be dried without supplying water. The growth of mold can be prevented by drying theevaporation filter 30 and thepre-evaporation filter 35. The electric fan preferably has a function of adjusting the speed of supplying water in order to adjust the temperature of air. In addition, for drying theevaporation filter 30 and thepre-evaporation filter 35, a dryingfan 15 can be mounted in the flow channel between theevaporation filter 30 and thepre-evaporation filter 35, for example. In this case, by rotating the dryingfan 15 for about 1 hour by using a timer after the switch of the electric fan is turned off, the growth of mold in theevaporation filter 30 and thepre-evaporation filter 35 can be prevented. - In the electric fan of the present invention, a dustproof filter or an air cleaning filter may be mounted upstream from the
evaporation filter 30 or thepre-evaporation filter 35, for example. In this way, the life of theevaporation filter 30 or thepre-evaporation filter 35 can be increased, and clean air is discharged from the blowingport 12. Additionally, theevaporation filter 30 or thepre-evaporation filter 35 may have a function of dustproofing and air cleaning. Further, a pre-filter made from a polyester or a modacrylic fiber may be mounted in thesuction port 11. - In the electric fan of the present invention, a cooling
coil 50 that is an indirect heat exchanger for cooling the air passed through theevaporation filter 30 is mounted downstream from theevaporation filter 30, as shown inFIG. 1 . Additionally, a cooler (chiller 51) is mounted for cooling a coolant flowing inside the cooling coil. - The cooling efficiency of air by the
evaporation filter 30 is affected by the temperature of the air suctioned (ambient temperature) and the temperature of the water introduced to theevaporation filter 30. When the ambient temperature is increased, not only the temperature of the air suctioned from thesuction port 11 but also the temperature of the water in thetank 41 are increased, whereby it becomes difficult to cool air to a desired temperature. This is particularly notable for the large flow rate fan having a large blade diameter, and a person does not feel cool from the air blown from the blowingport 12 so much when the ambient temperature is increased. On the other hand, as the present invention, by mounting a coolingcoil 50 downstream from anevaporation filter 30 and by flowing a coolant cooled forcibly with achiller 51 inside the coolingcoil 50, a person easily feels cool from the air blown from a blowingport 12 even if the ambient temperature is increased. Further, as described above, by forming at least an inner surface of ahousing 10 with a heat insulating material and by mounting the evaporation filter 30 (and a pre-evaporation filter 35) and atank 41 inside thehousing 10, the temperature increase of the water in the evaporation filter 30 (and the pre-evaporation filter 35) or thetank 41 can be suppressed. In a traditional electric fan having an evaporation filter, the evaporation filter is exposed to the outside. In particular when the electric fan is used for outdoor space or at a building entrance, sunlight directly illuminates the exposed part of the evaporation filter, and then the temperature of the water in the evaporation filter and the tank is greatly increased. However, in the configuration of the present invention as described above, the electric fan is not sensitive to the ambient temperature and the direct sunlight. - Specific examples of the indirect heat exchanger include multi-tubular heat exchangers, coiled heat exchangers, plate heat exchangers, and spiral heat exchangers, and a heat exchanger used can be suitably selected depending on the cooling performance. As the
chiller 45, for example, a relatively small chiller having an electric power for cooling of 1 to 10 kW can be used. Although the water cooled at about 2° C. is discharged from thechiller 51, the water is heated to 10° C. or higher by the coolingcoil 50, and therefore the problem of water condensate does not tend to occur. Although heat is generated in thechiller 51, the heat can be dissipated, for example, by mounting aheat dissipating fan 16 a on the rear surface of thehousing 10 of the electric fan. - In the electric fan of the present invention, a
mist sprayer 60 is preferably mounted on the peripheral of the blowingport 12 downstream from theaxial flow fan 20, as shown inFIG. 1 . In this way, mist can be introduced into air, and eventually, the feeling temperature of the cool wind which is blown from the blowingport 12 can be decreased. - The electric fan of the present invention having the configuration as described above can blow cool wind efficiently even if the electric fan is a large flow rate fan having a large blade diameter.
- Although the main object of the electric fan of the present invention is to perform cooling function as well as blowing function of air, the electric fan may be configured to perform heating function by switching instead of cooling function. In this case, the indirect heat exchanger mounted can be utilized effectively. That is, by mounting a
heater 52 for heating a heat medium flowing inside the indirect heat exchanger, the air passing through the indirect heat exchanger can be heated. Additionally, an external heater (anelectric heater 80 inFIG. 1 ) can be mounted in the flow channel of air for heating the air directly. - In order to achieve more effective heating function, the electric fan preferably has a
hot wind generator 70, and ahot wind discharger 71 which is mounted so that the hot wind from thehot wind generator 70 is discharged along the rotation direction of the air from theaxial flow fan 20. Thehot wind discharger 71 is preferably mounted downstream from the axial flow fan. In this way, hot wind at about 350° C., for example, which is generated from thehot wind generator 70 is discharged in a condition that hot wind is easily mixed to the flow of air, and thereby the heating efficiency of air is increased. As thehot wind generator 70, a hot wind generator having an electric power for heating of 5 to 15 kW can be used, for example. Although heat is generated around thehot wind generator 70, the heat can be dissipated, for example, by mounting aheat dissipating fan 16 b on the rear surface of thehousing 10 of the electric fan. - One specific configuration of the
hot wind discharger 71 is that a hotwind discharging hole 71 b is formed on a ring-shapedtube 71 a and that abaffle 71 c is mounted on the periphery of the hotwind discharging hole 71 b so that the hot wind is discharged along the rotation direction of the ring, as shown inFIG. 5 as the enlarged view. The ring-shaped tube 51 a that is thehot wind discharger 71 is disposed coaxially with theaxial flow fan 20. In this way, when the hot wind generated from thehot wind generator 70 is discharged from the hotwind discharging hole 71 b on the ring-shapedtube 71 a, the hot wind is directed to the rotation direction of the air from theaxial flow fan 20 by the effect of thebaffle 71 c. Therefore, the hot wind is discharged in a condition that the hot wind is easily mixed to the flow of air, and thereby the heating efficiency of air is increased. - When the electric fan is operated as a heater, water is not typically supplied to the
evaporation filter 30 or thepre-evaporation filter 35. However, water may be supplied to theevaporation filter 30 or thepre-evaporation filter 35. If water is supplied to theevaporation filter 30 or thepre-evaporation filter 35, the heating efficiency is decreased but the air can be humidified. Additionally, Ag ion ceramic balls can be put in abox 48 mounted in thetank 41 containing water, to suppress the generation of bacteria and to perform air cleaning function. By using a bactericidal lamp instead of the Ag ion ceramic balls, the generation of bacteria can be suppressed and air cleaning function can be performed as well. The position of the bactericidal lamp mounted may be in thetank 41 or may be in the middle of thewater supplying pipe 42. - The electric fan having the configuration as described above can blow warm wind efficiently even if the electric fan is a large flow rate fan having a large blade diameter.
- For example, a caster with rock mechanism may be mounted on the lower part of the
housing 10 of the electric fan of the present invention, to obtain a movable electric fan. Additionally, the electric fan may have a configuration in which accessories such as switches for operating the electric fan of the present invention can be retracted inside, to obtain an all-weather electric fan. - 10 housing
