Description

  The present invention relates to a humidifier that can efficiently humidify air and is easy to handle with a simple structure.

  Conventionally, a steam method, an ultrasonic method, and the like are known as humidifiers.

  1) A steam-type humidifier generates water vapor by supplying water from a built-in tank to an evaporating dish heated by a heater, and sends the water vapor to the outside with a blower or the like to bring it into contact with outside air. Moisture is given to the air.

  In steam-type humidifiers, when water vapor is sent out from the outlet, some of it is cooled at the edge of the outlet and adheres as water droplets. There is a case. Moreover, since the water droplets adhering to the air outlet are not used for humidifying the air, the efficiency is lowered, and the water is quickly reduced in spite of the humidified state. Furthermore, in the steam system, high-temperature water vapor blows out from the outlet, which may cause burns.

  2) An ultrasonic humidifier supplies water from a built-in tank to an atomization chamber provided with an ultrasonic generator, and vibrates the water in the atomization chamber with ultrasonic waves. Atomize. In this way, the mist drifting near the water surface is sent to the outside by a blower or the like to humidify the air.

  In an ultrasonic humidifier, if impurities such as calcium are mixed in the water, the crystals may adhere to the surface of the ultrasonic generator and reduce the function of the ultrasonic generator. May not be humidified. Further, when a part of the mist is sent out from the air outlet, it becomes a water droplet and adheres to the edge of the air outlet and cannot be used for humidification.

  In addition to these steam systems and ultrasonic systems, there is a vaporization system in which water is evaporated and humidified. Vaporizing type humidifiers are arranged with a humidifying part made of non-woven fabric with its lower end immersed in a water storage tank, sucking up water by the capillary action of the non-woven fabric and blowing air to the sucked-up water to evaporate the water. To be humidified.

In addition, there is a water mist that is humidified by contacting with air (hereinafter also referred to as a mist method). Specifically, the water stored at the bottom of the container is pumped up by a screw pump, and the water is supplied to a circular drainer rotating at high speed. Then, water is blown in the radial direction by a draining plate and collided with a mist generator to form mist-like water droplets, and the mist-like water droplets are sent to the outside by a blower or the like to give moisture to the air and humidify it (patent) Reference 1).
Japanese Patent Laid-Open No. 7-243677 (pages 2 to 3)

  However, the above-described vaporization type and mist type humidifiers have the following problems.

  Vaporizing humidifiers use the capillary action of non-woven fabric to suck up water, so there may be cases where a sufficient amount of water cannot be supplied to the upper part of the vaporizing section that blows air, and the amount of water that evaporates is insufficient. However, humidification may not be performed properly.

  In addition, the mist method makes the stored water mist and sends it out to the outside, so that water droplets adhere to the edge of the air outlet and so on, so that the outer surface of the device gets wet, and it takes time and effort to wipe and clean. There is. In addition, the water draining wheel rotates to make small water droplets by hitting the water against the mist-generating slit, and the air is taken in from the opening groove and mixed to humidify, so the humidification efficiency changes depending on the size of the water droplets. Humidity may become unstable.

According to the humidifying device of the fourth aspect, it is possible to prevent water from jumping excessively when supplying water to the carrier, so that water can be smoothly supplied to the carrier.

  The humidifying device according to claim 5 is provided with an inlet at the lower end of the upper cover and a blower outlet at the upper surface, and a blower is disposed on the downstream side of the humidifying unit on the flow path. As a means, a cylindrical pumping pipe is used as a male screw type rotor, or a pumping pump having a rotating shaft with an impeller connected to a lower end thereof, and the rotor or the rotating shaft is connected to the propeller of the blower. Thus, it is possible to rotate integrally on the same axis.

  According to the humidifying device of the fifth aspect, it is possible to reduce the size while avoiding the complexity of the structure of the device. And since the rotating shaft of the said rotor or impeller and the propeller of the said air blower can be integrally rotated on the same axis | shaft, these can be rotated with one drive device, and also simplification of a structure is aimed at. be able to.

It is characterized by being attached to.

  According to the humidifying device of the sixth aspect, by making the dispersion plate integrally rotatable with the connecting shaft, the water pumped up by the pumping means can be supplied uniformly to the carrier. Moreover, since it is attached to the connecting shaft, it can be rotated by the rotor or the rotating shaft or the propeller shaft of the blower and a single driving device, and the humidification efficiency can be improved without hindering downsizing of the device. Can do.

  The humidifying device according to claim 7 is provided with a receiving plate for partitioning from the upper cover at an upper portion of the water storage tank, and the receiving plate is provided with an inclination from a central portion toward an inner surface of the water storage tank, It is characterized by providing a through hole at the lower end.

  According to the humidifying device of claim 7, since the water storage tank and the upper cover are partitioned by the receiving plate, even when the device is inclined, it is difficult for water to leak from the water storage tank, for example, accompanied by shaking of an automobile or the like. Can be used with confidence in the vehicle. Moreover, the water which fell on the said receiving plate can be guide | induced to the said through-hole by inclination, and can be returned again to the said water storage tank. Therefore, the water in the water storage tank can be used for humidification while circulating in the apparatus, so that the water can be used without waste.

  The humidifier according to claim 8 is characterized in that the carrier has a fibrous structure. According to the humidifying device of claim 8, since the carrier has a fibrous structure, air can more easily flow through the carrier and can easily retain moisture, thereby improving the processing capacity. The humidification efficiency in a predetermined time can be improved.

  The humidifying device of the present invention made using such means has the following effects.

  Hereinafter, an embodiment of a humidifier according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a cross-sectional view of the humidifier 1 cut in the longitudinal direction. In addition, the arrow shown with the continuous line in the figure has shown the flow of air, and the arrow shown by the dotted line has shown the flow of water.

  As shown in FIG. 1, the humidifier 1 has a vertically long cylindrical casing 2 in which an upper cover 21 having an air inlet 21 a and an air outlet 21 b is detachably attached to an upper portion of a water storage tank 5. Thus, an axial flow fan (blower) 3 for blowing is disposed on the upper portion of the upper cover 21 and provided with an outlet 21b, and an inlet 21a is provided at the lower end.

  A humidifying unit 4 for bringing water and air into contact with each other is disposed on the flow path from the inlet 21a to the outlet 21b. Pumping means 6 for pumping and supplying water from the water storage tank 5 to the humidifying unit 4 Is provided.

  The humidifying unit 4 includes a carrier 42 having a fibrous structure and a holder 41 on which the carrier 42 can be mounted. The carrier 42 has a fibrous structure. Therefore, the gap serves as an air passage so that the air taken in from the inlet 21a can be circulated and the water supplied to the humidifying unit 4 can be held.

  The carrier 42 is not limited to one having a fibrous structure, and may be any material that has an air flow path and can retain moisture on the inner surface of the air flow path. The holder 41 may be filled with a granular porous substance that can hold the air, and air may be passed through the gap between the porous substances.

  The holder 41 is a short cylindrical container having an outer diameter that is substantially the same as the inner diameter of the upper cover 21 and having an open upper side. The insertion tube 41a is provided in the center, and a through hole 41b for venting and draining is formed around the insertion tube 41a. An overhang portion 41c is formed on the upper end portion of the side wall, and the axial fan 3 is placed and fixed on the overhang portion 41c.

  The axial fan 3 includes a propeller 31 that is driven by a small motor (not shown) built in the shaft portion. At the center of the lower surface of the propeller 31, a connecting shaft 32 for connecting to a rotor of a screw-type pumping pump, which will be described later, rotates on the same shaft as the propeller 31 and rotates integrally with the holder 41. It is attached in a state of being inserted through the insertion tube 41. Further, a photocatalytic filter 33 coated with a coating agent containing a photocatalyst mainly composed of titanium dioxide is attached to the upper end opening of the axial fan 3, that is, the outlet 21b.

  On the other hand, pumping means 6 is arranged in the water tank 5. The pumping means 6 is a screw type pump with a male screw type rotor 62 built in a pumping pipe 61 having a circular cross section. The upper end of the pumping pipe 61 is inserted into and removed from the lower end of the insertion pipe 41 a of the holder 41. Connected freely. In addition, a receiving plate 63 that is inclined upward toward the outer side is formed on the outer periphery of the intermediate portion of the pumping pipe 61. The receiving plate 63 is formed in such a length that its outer peripheral end reaches the inner surface of the water storage tank 5, and the pumping pipe 61 places the outer peripheral end of the receiving plate 63 at the upper end of the water storage tank 5. Supported by the state.

  A gap S is provided between the lower surface of the pumped water pipe 61 thus supported and the inner bottom surface of the water storage tank 5, so that the water in the water storage tank 5 can be introduced into the water pumping pipe 61 from this gap S. It has become. The receiving plate 63 is formed with a through hole 63a at the lower end (connection portion with the pumping pipe 61) so that the water that has flowed down to the receiving plate 63 can be collected at the central portion and returned to the water storage tank 5. .

  The rotor 62 built in the pumping pipe 61 has a lower end portion of the connecting shaft 32 inserted into an upper end portion thereof, and can rotate integrally with the connecting shaft 32 (in other words, the propeller 31). The lower end portion of the rotor 62 is loosely fitted to a columnar support portion 22a projecting from the central portion of the bottom surface inside the water storage tank 5, and the runout during rotation is prevented.

  A disc-shaped dispersion plate 7 is fitted into the connecting shaft 32 so as to be positioned above the humidifying unit 4. The dispersion plate 7 is formed such that the outer peripheral portion thereof is inclined so that the outer peripheral end thereof faces obliquely downward, and rotates integrally with the connecting shaft 32.

  Next, the operation of the humidifier 1 will be described.

  First, the upper cover 21 is lifted, and the rotor 62 is removed from the water storage tank 5 while being extracted from the water pump 61. Then, the pumping pipe 61 is taken out from the water storage tank 5 (at this time, the receiving plate 63 formed integrally with the water pumping pipe 61 is also taken out at the same time). Then, the upper cover 21 is attached to the water tank 5.

  Then, the humidifier 1 is disposed at a predetermined location, and the propeller 31 is rotated by supplying power to the motor of the axial fan 3. When the propeller 31 rotates, the dispersion plate 7 attached to the connecting shaft 32 and the rotor 62 connected through the connecting shaft 32 rotate at the same time, and the rotation of the rotor 62 causes the clearance S to enter the pumping pipe 61. Water in the water storage tank 5 is introduced and pumped up to the height of the dispersion plate 7. The pumped water is applied to the central portion of the rotating dispersion plate 7, is blown in the radial direction, and is supplied to the surrounding carrier 42. Since the outer peripheral portion of the dispersion plate 7 is formed to be inclined downward, it is difficult to cause a bias that water is excessively supplied and supplied only to the vicinity of the side wall of the holder 41.

  On the other hand, when the propeller 31 of the axial fan 3 rotates, external air is taken into the casing 2 from the introduction port 21 a of the upper cover 21, and this taken-in air passes through the through hole 41 b of the holder 41. Moisture is supplied and humidified by entering the carrier 42 and contacting the water with the carrier 42. At this time, the water flows from the top to the bottom of the carrier 42 and, conversely, the air flows upward from the bottom of the carrier 42, so that the water and the air are in countercurrent contact with the carrier 42, and the air Is humidified to a humidity close to saturation.

  The humidified air exits from the carrier 42, is guided to the axial fan 3, and is sent out of the casing 2 from the outlet 21b on which the photocatalytic filter 33 is mounted. Since the humidified air can be sterilized by passing through the photocatalytic filter 33 in this way, for example, even when germs are generated in the water of the water storage tank 5 supplied to the air taken in as moisture, the sterilized clean Fresh humidified air can be sent to the outside, and germs can be prevented from diffusing into the air.

  By circulating the indoor air through the humidifier 1, the air can be prevented from being dried and the air can be kept clean. Further, unlike the steam type, the humidifier 1 does not excessively humidify the air, so that the room can be kept at a comfortable humidity.

  The surplus water supplied to the carrier 42 flows down from the through hole 41b on the bottom surface of the holder 41 onto the receiving plate 63 and is collected around the pumping pipe 61 by the gradient of the receiving plate 63, and then the through hole 63a. Is returned to the water tank 5. Then, the water is pumped up again by the pump and supplied to the carrier 42 for humidification of the air.

  Moreover, since the humidifier 1 can prevent the water leakage of the water storage tank 5 by the receiving plate 63, even when the casing 2 is inclined, the water of the water storage tank 5 does not leak outside from the inlet 21a.

  The pump of the humidifying device 1 of this embodiment is provided with a male screw type rotor 62 in the pumping pipe 61. Instead of the rotor 62, a spiral groove is formed on the outer peripheral surface of the rotating shaft. A rotor can also be used (not shown). In addition, as shown in FIG. 2, a water pump provided with an impeller 64 'may be used. In this pump, a centrifugal impeller 64 'is connected to the lower end of a rotating shaft 65' inserted into the pumping pipe 61 '. By rotating the impeller 64', the pumping pipe 61 'is rotated. The water in the water storage tank 5 can be sucked and pumped from the lower end opening. The impeller 64 'may be, for example, a spiral type other than the centrifugal type. Moreover, the same code | symbol is used for the thing similar to the humidification apparatus 1 which uses the screw type pumping pump mentioned above.

  The rotating shaft 65 ′ to which the impeller 64 ′ is connected has the lower end portion of the connecting shaft 32 inserted into the upper end portion, and can rotate integrally with the propeller 31. Further, the lower end portion of the water pumping pipe 61 ′ is expanded in diameter so that the impeller 64 ′ can be stored therein, and a storing portion 61a ′ is formed therein, which stores the water accelerated by the impeller 64 ′ and sent to the side. A water guiding portion 61b ′ for guiding the portion 61a ′ to the upper side is provided.

  Thus, by using the pump as shown in the embodiment as the pumping means 6, it becomes unnecessary to manage the water level of the water storage tank 5 and it is easy to handle, and a ball tap (floating bag) for detecting the water level is not required. The structure can be simplified.

  In other words, taking the humidifier of the above-mentioned prior art document 1 as an example, this humidifier generates centrifugal force in the water in the vortex outer cylinder by rotating the impeller, and rotates to the water by this centrifugal force. By giving motion, the water is raised along the inner wall surface of the vortex outer cylinder and pumped up. For this reason, it is necessary to maintain the water level of the water tank portion at a predetermined height using a ball tap or the like in order to pump the water up to the overflow reflector with a low head.

  Therefore, if a pumping pump such as the screw type as shown in the embodiment is used as the pumping means, the water can be reliably pumped even if the water level of the water tank becomes low, so that the water in the water tank does not become empty. This is because water level management is not particularly necessary.

  In addition to the above-described carrier, for example, a carrier as shown in FIGS. 3A and 3D can be used. The carrier 42 'in FIG. 3 (a) is integrally formed with the holder 41', and the bottom plate of the holder 41 'is provided with a large number of through holes in a lattice shape (see FIG. 3 (b)). The carrier 42 'is configured as an air flow passage 42'a. These flow passages 42'a are provided with a diameter of 2 to 10 mm. The number of the flow passages 42'a is such that the opening area of all the flow passages 42'a is about 20 to 50% of the area of the bottom plate (opening ratio). ).

  In such a leak shelf type, as shown in FIG. 3 (c), the water (broken arrow) supplied to the carrier 42 'flows down in the flow passage 42'a, on the contrary, The taken-in air (solid arrow) flows upward from the lower side of the flow passage 42'a. Therefore, since water and air are in countercurrent contact with each other and the humidification efficiency is improved, it is possible to humidify to a humidity close to a saturated state.

  FIG. 3D shows a carrier 42 ″ and a holder 41 ″ provided separately. The carrier 42 ″ is formed in a plate shape using a synthetic resin, a non-woven fabric, or the like, and is provided with a flow passage 42 ″ a as in FIG. The number of the flow passages 42 ″ may be provided so that the opening ratio is about 20 to 50% with respect to the opening area of the lower opening 41 ″ a of the holder 41 ″. It is mounted above the lower opening 41 ″ of 41 ″ and, like the carrier 42 ′ in FIG. 3A, humidifies the air by bringing water and air into countercurrent contact in the flow passage 42 ″. Yes.

  As mentioned above, since the humidifying device 1 described above is compact and is not easily leaked by the receiving plate 63 at the upper part of the water storage tank 5, even if it is installed in a narrow and easily swayed vehicle, it does not get in the way and can be used with confidence it can. When installing in the vehicle in this way, the power of the axial fan 3 may be taken from the cigar lighter. For example, a power storage unit for storing a power source such as a battery is provided at the bottom of the casing so as to be integrated. If power is supplied from the power source to the motor of the axial fan 3, wiring for the external power source can be omitted, the wiring is not obstructed, and the location can be easily changed.

  Moreover, the humidification apparatus 1 can also be used as a deodorizing apparatus, if a deodorizing liquid is put into the water storage tank 5 instead of water. That is, when deodorant liquid is put into the water storage tank 5 in the same manner as in the case of water, and the propeller 31 is rotated by supplying power to the axial fan 3, the rotor 62 or the rotary shaft 65 ′ of the pump is rotated and the water storage tank 5 is rotated. The deodorant liquid is pumped up.

  The deodorized liquid pumped up is supplied while being dispersed throughout the carrier 42 by the rotating dispersion plate 7, while the propeller 31 rotates to enter the casing 2 from the inlet 21 a of the upper cover 21. Outside air is taken in. The taken-in air enters the holder 41 through the through hole 41b of the holder 41, and comes into contact with the deodorizing liquid through the carrier 42 therein.

  Since the odor component contained in the air in contact with the deodorant liquid is adsorbed and removed by the deodorant liquid, a strange odor or bad odor is removed. The air deodorized in this way is sent out of the casing 2 from the outlet 21b where the photocatalytic filter 33 is mounted. At this time, since germs can be sterilized by passing through the photocatalytic filter 33, when germs are generated in the deodorizing liquid of the water storage tank 5, the germs are mixed into the air when the air and the deodorizing liquid come into contact with each other. It can be prevented from being released to the outside.

  By circulating air through the humidifying device (in this case, the deodorizing device) 1, the air in the room can be kept clean while removing off-flavors and bad odors. If it is installed, the smell of the cigarette smoked by the smoker can be quickly erased, and the discomfort of the non-smoker who rides can be reduced.

  Moreover, since the humidifier and deodorizer described above are less likely to leak water (liquid), they can be used as a humidifier or deodorizer for passenger cabins other than vehicles that cause shaking, such as automobiles. In addition, because it is compact and does not take up space, it does not get in the way when placed in offices, hospitals, nursing homes, etc., or restaurants, entertainment facilities, etc. Since high temperature steam is not blown out as in the formula, it can be used safely without fear of burns. Furthermore, in the case of a humidifier, the air is humidified by bringing it into contact with water, so the humidity does not become too high. If it is installed in a refrigerator or food storage, the humidity of the air in the refrigerator is reduced. It can be kept moderate and food can be stored in a better state.

  Moreover, when using as a deodorizing apparatus, it can install in a refrigerator or food storage, can remove the odor which comes out of food, and can prevent the smell of other foods from moving. In addition to increasing the capacity of the water storage tank by enlarging the casing and increasing the capacity of the axial fan, the capacity of the tank can be increased in places where odors and odors are likely to occur, such as garbage disposal plants and sewage treatment plants. By installing it, it is possible to reduce bad odors of garbage, odors such as human waste and the like, and to improve the working environment.
