  An air purifying filter 102 having a dust collecting and deodorizing function as an air cleaning means is disposed at the upper part of the air inlet 105. The air purifying filter 102 is supported below the air purifying filter 102, and the air inlet 105 is divided into two parts. The empty partition plate 2 is formed.

  An emptying bypass damper 3 having a damper mechanism is disposed as a flow adjustment means for emptying at a lower part of the emptying partition plate 2 and can be rotationally driven so as to open and close the lower side portion of the intake port 105 from the partition plate 1. In the open state, the outside of the main body 101 and the inside of the main body 101 can be ventilated.

  A fine water droplet generating means 4 is provided as a humidifying means at the lower part of the main body 101 and downstream of the air purification filter 102 with respect to the air flow, and heating for heating the air upstream of the fine water droplet generating means 4. A nichrome heater 5 is provided as a means.

  Further, a tray 6 for storing humidifying water is provided in the lower part of the main body 101, and the fine water droplet generating means 4 can supply water from here. The upstream side and the downstream side of the fine water droplet generating means 4 are separated by a humidifying partition plate 7, and the humidified bypass wind is connected to a part of the humidifying partition plate 7 so that the upstream side and the downstream side of the fine water droplet generating means 4 communicate with each other. A path 8 is provided, and a humidifying bypass damper 9 having a damper mechanism is provided as a humidifying flow rate adjusting means so that the humidifying bypass air path 8 can be opened and closed.

  Here, as shown in FIG. 2, the fine water droplet generating means 4 includes a rotating disk 10 having a disk shape and a horizontally arranged disk surface, and a conical and hollow cylinder having a conical bottom surface side. Connected to the lower surface of the turntable 10 and opened to the turntable 10, a water absorption pipe 11 disposed so that the apex side of the conical shape is immersed below the water surface of the tray 6, and the turntable 10 and the water absorption pipe 11 It is constituted by a humidifying motor 12 that pivotally supports the central portion and rotates integrally to refine water.

  In the first embodiment, the fine water droplet generating means 4 is used as the humidifying means. However, any means may be used as long as it uses a humidifying system used in a so-called home / industrial humidifier. Vaporizing type using a filter, a hybrid type equipped with heating means at the same time before the vaporizing type and the vaporizing filter, an ultrasonic type using an ultrasonic vibration element, a spray type that ejects pressurized water, pressurized air and water The same effect can be obtained even with a two-fluid spray type that jets mixed.

  In the first embodiment, the nichrome heater 5 is used as a heating means. However, any heater capable of heating air may be used, and similar effects can be obtained with a halogen heater, a ceramic heater, a semiconductor heater, or the like.

  A first exhaust port 13 and a second exhaust port 14 are opened on the top surface of the main body 101, and a scroll-like casing 109 disposed inside the main body 101 is connected to the first exhaust port 13, the second exhaust port 14, and the like. Communicate. Further, the casing 109 has a first suction port 15 and a second suction port 16 opened in the front and rear directions of the main body 101 inside the main body 101, respectively. 102, a humidified air passage 110 extending from the fine water droplet generating means 4, the first suction port 15, and the first exhaust port 13, and the pre-filter 1, the air purifying filter 102, the second suction port 16, and the second exhaust port 14 from the intake port 105. An air fresh air passage 17 leading to is formed.

  Here, FIG. 3 is a schematic cross-sectional view showing the internal structure of the casing 109 in detail. As shown in FIG. 2, in the casing 109, a disk-shaped main plate 18, and an impeller 108 in which a plurality of first blades 19 and a plurality of second blades 20 are respectively provided in an annular shape on both sides of the main plate 18. The impeller 108 is connected to a fan motor 103 as a motor via a drive shaft 21, and is supported so as to rotate by driving the fan motor 103. Further, the impeller 108 is disposed in such a direction that the first blade 19 is disposed in the humidified air passage 110 and the second blade 20 is disposed in the empty air passage 17.

  Further, the casing 109 is divided into a humidified air passage 110 and an empty air passage 17 inside the casing 109 so that air in these two air passages does not flow as much as possible, and the air in each air passage can be boosted separately. Thus, the partition wall 22 is formed so as to face the outer peripheral end of the main plate 18.

  Next, paying attention to the impeller 108, as shown in FIG. 4, the blade inner diameter 23 of the plurality of first blades 19 provided on the humidifying air passage 110 side of the main plate 18 of the impeller 108 is set to d1, the empty air passage side. Assuming that the inner diameter 24 of the plurality of second blades 20 around the circumference is d2, the relationship between d1 and d2 is d1 <d2, and the humidified air passage 110 having high ventilation resistance is passed through the humidifying means. The static pressure-air volume characteristic on the humidified air passage 110 side of the impeller 108 is close to high static pressure so that more air can be ventilated. Here, in order to reduce the airflow resistance, the blade inner diameter 23 of the first blade 19 and the opening diameter of the first suction port 15 are made substantially the same.

  Further, as shown in FIG. 4, the casing 109 formed in a spiral shape has a scroll 25 on the empty air passage 17 side and a scroll on the humidified air passage 110 side having a smaller expansion angle than the scroll 25 on the empty air passage 17 side. 26. Therefore, a large amount of air can be passed through the humidified air passage 110 having a high ventilation resistance. Accordingly, the width 28 of the second exhaust port 14 on the side of the air fresh air passage 17 partitioned by the partition wall 22 of the first exhaust port 13 and the second exhaust port 14 opened in the casing 109 is the first on the humidified air passage 110 side. It is configured to be wider than the width 27 of the exhaust port 13. Therefore, when the exhaust port height 29 of the scroll 26 on the humidified air passage 110 side is H1, and the exhaust port height 30 of the scroll 25 on the empty air passage 17 side is H2, the relationship is H1 <H2. The blade outer diameters 31 of the first blade 19 and the second blade 20 have the same value F. If the outlet angle 32 of the first blade 19 is β1, and the outlet angle 33 of the second blade 20 is β2, β1 <β2. Therefore, a large amount of air can be ventilated through the humidified air passage 110 having high ventilation resistance. When the number of the first blades 19 provided around the main plate 18 is n1 and the number of the second blades 20 is n2, a relationship of n1> n2 is established, and a large amount of air can be passed through the humidified air passage 110. It is like that.

  The operation in the above configuration will be described. When the fan motor 103 and the humidifying motor 12 are driven (hereinafter referred to as a humidified air cleaning mode), the air is cleaned from the outside of the main body 101 through the air inlet 105, the prefilter 1 and the air cleaning filter 102, and the air is introduced into the main body 101. Is sucked. The sucked air is shunted inside the main body 101, and most of the air is pressurized by the fine water droplet generating means 4 as the humidifying means, the first suction port 15 of the casing 109, and the first blade 19, and passes through the first exhaust port 13. It passes through the humidified air passage 110 leading to the outside of the main body 101 and is discharged to the outside of the main body 101. Further, when the air does not pass through the humidified air passage 110, the air passes through the air filter 102, and then is pressurized by the second suction port 16 and the second blade 20 of the casing 109 to reach the outside of the main body 101 through the second exhaust port 14. It passes through the clear air passage 17 and is discharged to the outside of the main body 101.

  Here, the operation of the fine water droplet generating means 4 will be described. Of the water stored in the tray 6, the water in the hollow interior of the water absorption pipe 11 rotates the water absorption pipe 11 by driving the humidifying motor 12, and the inner wall of the water absorption pipe 11 is blocked by the viscosity and rotation centrifugal force of the water. Then, it is lifted up to the upper surface of the turntable 10. The water pumped up to the upper surface of the turntable 10 moves in the radial direction of the turntable by centrifugal force due to the rotation of the turntable 10 and reaches the end face of the turntable 10. The balance between the surface tension of the water and the centrifugal force is lost on the end face of the turntable 10, and the moment when the centrifugal force increases, the water drops from the end face of the turntable 10 into the air as fine water droplets having a diameter of 0.1 to 1 micrometer. Scatter. This fine water droplet and the air passing through the humidification air passage 110 are mixed and brought into gas-liquid contact, whereby the air is humidified. Note that the humidifying ability can be freely controlled by changing the number of rotations of the humidifying motor 12.

  In addition, when it is desired to perform only air cleaning without humidification, the fan motor 103 is driven, the humidification motor 12 is stopped, and the humidification bypass damper 9 is opened (hereinafter, this is referred to as an air purification mode). Called). At this time, the air purified from the outside of the main body 101 through the intake port 105, the pre-filter 1 and the air purification filter 102 passes through the humidification bypass air passage 8, passes through the first suction port 15 of the casing 109, and passes through the first blade 19. The air flow is boosted by the air and discharged to the outside of the main body 101, and the air flow passes through the second suction port 16 of the casing 109 as it is and is shunted by the second blade 20 and is discharged to the outside of the main body 101. Become. Accordingly, since the fine water droplet generating means 4 as the humidifying means having a high ventilation resistance can be passed through the main body 101 without passing through the portion, it is possible to clean a larger amount of air.

  Further, when it is desired to rapidly humidify such as when the drying is severe, rapid humidification can be performed by driving the fan motor 103 and the humidifying motor 12 and opening the emptying bypass damper 3 (hereinafter referred to as this). Is called turbo humidification mode). In this case, in addition to the air sucked into the main body 101 through the intake port 105, the prefilter 1, and the air filter 102, the air that has passed through only the intake port 105 and the prefilter 1 can be sucked together. The sucked air passes through the same air path as in the humidifying mode, but there is a new air path that does not pass through the air-cleaning filter 102 with high ventilation resistance than in the humidifying mode. The air can be sucked into 101, and the amount of air passing through the fine water droplet generating means 4 as the humidifying means inevitably increases, so that the humidifying ability can be temporarily improved.

  As described above, the configuration, operation, and the like in the above-described embodiment are merely examples of the embodiment of the present invention, and the present invention is not limited to this.

  The air purifier with a humidifying function of the present invention is not only an air purifier with a humidifying function for home use that is portable and easy to handle, but also an air purifier with a humidifying function that is incorporated into an air conditioner in household and commercial facilities. It can also be applied to devices and the like.
