Description

  The present invention relates to a humidifier equipped with a filter that is arranged in a ventilation passage of wind generated by a blower and is humidified by water in a water tank, and an air cleaner.

  Indoor air contains various substances that are uncomfortable or harmful to the human body, such as dust, pollen, tobacco smoke, and exhaled air. Particularly in recent years, since the houses are airtight, such harmful substances are likely to stay in the room. For this reason, natural ventilation has been provided by opening windows in rooms as appropriate.

  However, it is the actual situation that natural ventilation cannot be performed as desired in areas where air pollution is severe, or in homes and workplaces where people suffer from hay fever. Under such circumstances, air purifiers having an air purifying function for purifying indoor air have been widely spread.

  A purification filter is attached to the front surface of the air cleaner, and a ventilation path provided with a blower is formed inside. The ventilation path extends from the front opening to the upper outlet. In such an air purifier, the air in the room, which is external air, is sucked into the ventilation path through the purification filter according to the rotation of the blower, and the sucked air is blown out from the air outlet to the room, which is outside. At that time, harmful substances contained in the air are removed by being collected, adsorbed and decomposed by the purification filter, thereby purifying the air.

  Some air purifiers also have a humidifying function for the purpose of adjusting indoor air to a more comfortable state. In an air purifier with a humidifying function, a humidifying filter containing moisture is arranged to block a part of the cross-sectional area of the ventilation path, and a part of the air purified by the purifying filter passes through the humidifying filter. It is configured to take in moisture when it is done and to be humidified thereby (see, for example, Patent Document 1). There is also known a humidifying device that rotates a disk-shaped humidifying filter arranged in a vertical posture in order to efficiently absorb water in the entire humidifying filter (see, for example, Patent Document 2).

  The humidifying device as in Patent Document 2 includes a water tank for storing water, and the humidifying filter is arranged in a vertical posture so that a part of the circumferential direction is submerged in the water tank, and is placed at the central position of the humidifying filter. It is configured to be able to rotate in the circumferential direction around a rotation shaft in a lateral posture orthogonal to the side surface. By rotating in the circumferential direction, the humidifying filter is continuously submerged in the circumferential direction, and water is sucked up from the submerged part to the non-submerged part, so that the entire humidifying filter spreads. As a result, the humidifying filter efficiently absorbs water throughout the entire humidifying filter.

Furthermore, by blowing air to one side of the humidified filter that has absorbed water, the air that has passed through the humidified filter absorbs moisture, and the absorbed air is blown to the outside of the humidifier.

  By the way, in the above-described conventional air cleaner with a humidifying function, the ability to purify air and the ability to humidify both depend directly on the air volume, that is, the degree of rotation of the blower. That is, if the rotational speed of the blower is increased and the air volume is increased, both capacities are increased simultaneously. Conversely, if the rotational speed of the blower is decreased and the air flow is decreased, both capacities are decreased simultaneously. Therefore, for example, when the humidity is low and it is desired to make the humidification function work positively, the rotational speed of the blower is increased to increase the humidification capacity. However, in this case, since only a part of the air flowing through the ventilation path passes through the humidification filter, it cannot be said that the efficiency of humidification is good, and noise is generated if the rotational speed of the blower is too high.

  The applicant of the present invention provides a humidifying filter in which a submerged region and a non-submerged region are provided adjacent to each other in the circumferential direction, and the humidifying filter is configured to rotate in the circumferential direction by a rotation drive mechanism. A humidifier was first developed to allow the humidifying filter to absorb water or prevent the humidifying filter from absorbing water while the humidifying filter was placed in a vertical position.

  In this humidifying device, when a humidifying operation is performed by rotating a disc-shaped humidifying filter and a non-humidifying operation is performed, a non-immersed area must be provided in a disc shape. A state where the region is constantly sucking up water is preferable. Conversely, when performing non-humidifying operation, it must be stopped in a non-immersed area.

In addition, after removing the disk-shaped humidifying filter from the housing and performing maintenance, it is unclear which position the non-immersed area of the humidifying filter is in when it is installed in the housing because the humidifying filter rotates freely. is there.
Therefore, when performing non-humidifying operation, the humidifying filter rotates depending on the position of the non-immersed area of the disc-shaped humidifying filter, and the submerged area (humidifying range) sucks water. There has been a problem of discomfort due to the release of air containing moisture in the air during humidification operation.

  The present invention has been made in view of the above-described problem, and when rotating a humidifying filter having a disk shape, an outer peripheral portion is submerged in a water tank and a non-submerged portion which is not submerged is separated in the circumferential direction when rotating. When the filter is not rotating, the non-water-immersed part is arranged vertically and at the bottom, so that air that does not contain moisture from the filter can be discharged indoors during non-humidifying operation. An object of the present invention is to provide a humidifier and an air purifier capable of creating the above.

The non-immersed part is arranged vertically and at the lowermost part.

  In this invention, when the filter having the submerged part and the non-submerged part spaced apart in the circumferential direction is non-rotating, the non-submerged part is arranged vertically and there is no risk of sucking up water in the aquarium. During operation, air containing no moisture from the filter can be released into the room, and a comfortable space can be created.

In the humidifier according to the present invention, it is preferable that the non-water-immersed portion is heavier than the water-immersed portion.
In this invention, when the filter is not rotating, it is possible to vertically position the non-water-immersed part by its own weight, and it is possible to eliminate the concern of positioning the non-water-immersed part vertically. It is possible to automatically position the non-immersed part vertically.

Further, in the humidifier according to the present invention, the filter includes a filter body having the water-immersed part and a non-water-immersed part, and an annular frame body that holds an outer peripheral part of the filter body, and the rotation The driving mechanism has a roller that rotates the filter in contact with the outer peripheral surface of the frame body and a motor that rotates the roller, and the roller is separated from the uppermost position of the frame body in the circumferential direction. It is preferable to adopt a configuration arranged in the above.
In this invention, when the filter can be maintained, the filter can be configured to be movable in the direction opposite to the roller, so that the filter can be easily maintained without being obstructed by the roller. is there.

Further, in the humidifier according to the present invention, the filter includes a filter body having the water-immersed part and a non-water-immersed part, and an annular frame body that holds an outer peripheral part of the filter body, and the rotation The drive mechanism includes a roller that rotates the filter in contact with the outer peripheral surface of the frame body and a motor that rotates the roller, and inserts the filter in a radial direction and a lateral direction. And a housing for housing the filter and the rotation drive mechanism, and the roller is disposed at a location separated from the uppermost position of the frame body in the circumferential direction opposite to the insertion portion. It is preferable to have a configuration.
In this invention, since there is a drive gear on the side opposite to the insertion portion with respect to the filter, the filter can be inserted into the insertion portion without being obstructed by the drive gear. The surface can be in contact with the drive gear. Moreover, when taking out the filter in the housing, the filter can be taken out from the insertion portion without being obstructed by the drive gear, and the maintenance of the filter can be simplified.

Moreover, the air cleaner which concerns on this invention has the humidification apparatus of the above-mentioned invention, a suction opening and a blower outlet, the housing which accommodates the said humidification apparatus, and the said air blower pass the air which inhales from the said suction inlet A purification filter that allows the filter to be inserted into and removed from the housing, and the rotational drive mechanism contacts the outer peripheral surface of the filter when the filter is inserted into the housing. The humidifying filter is arranged to rotate.
In the present invention, by inserting the filter into the housing, the outer peripheral surface of the filter can be brought into contact with the rotation drive mechanism, and the filter can be taken out from the housing. It can be simplified.

Further, an air cleaner according to the present invention includes a housing having an inlet and an outlet, a water tank and a fan accommodated in the housing, a purification filter that allows air to be sucked from the inlet by the fan, and An air cleaner comprising a humidifying filter that can rotate in a ventilation path of wind generated by the blower and that can be inserted into and removed from the housing, and a rotation drive mechanism that rotates the humidifying filter.

In this invention, by inserting the humidification filter into the housing, the humidification filter comes into contact with the rotation drive mechanism and can rotate the humidification filter. Therefore, the filter is inserted / removed from the housing. When performing maintenance, this maintenance can be simplified.

  According to the humidifier and the air cleaner of the present invention, when the filter having the submerged part and the non-submerged part spaced apart in the circumferential direction is non-rotating, the non-submerged part is arranged vertically and may suck up water in the aquarium. Therefore, air that does not contain moisture from the filter can be released indoors during non-humidifying operation, and a comfortable space can be created.

Here, the air cleaner will be described with an example having a humidifying function and an ion releasing function.

  The air cleaner shown in the figure is placed on the floor or hung on a wall at a suitable place in the room during operation. In general, the housing 1 has a suction port 1a on the rear surface, and a suction port 1a of the housing 1. And the outer panel is constituted by the rear panel 2 having a plurality of small holes. The housing 1 has a rectangular parallelepiped shape as a whole, and has an external shape that stands vertically. A filter housing portion 1b that is greatly recessed in a rectangular parallelepiped shape is formed on the rear surface, and a humidifying filter 3 that will be described later is formed on one side surface. And the insertion part 1c for inserting a part of the water tank 4 from the lateral direction so as to be able to be taken out, and the recess 1d in which the water supply container 5 for supplying water to the water tank 4 and the other part of the water tank 4 are arranged are formed. . In the filter storage part 1b, the deodorizing filter 6 and the dust collection filter 7 as a purification filter are stored in an overlapped order from the rear side.

  The deodorizing filter 6 is responsible for adsorbing odorous components such as acetaldehyde, ammonia and acetic acid in the air. A non-woven fabric made of polyester is attached to a rectangular frame, and activated carbon is uniformly distributed on the frame. A polyester non-woven fabric is put on the top.

  The dust collection filter 7 plays a role of collecting fine dust, and is a so-called HEPA (High Efficiency Particulate Air) filter. The aggregate is made of a polyester / vinylon nonwoven fabric and a melt blown nonwoven fabric subjected to electrolithography is used as a filter medium. The antibacterial sheet made of a non-woven fabric subjected to hydroxyapatite processing is overlapped on the upper and lower surfaces of the folded anti-woven sheet and thermocompression bonded, and a frame made of a non-woven fabric with hot melt is welded.

  The deodorizing filter 6 and the dust collection filter 7 housed in the filter housing portion 1b are prevented from dropping from the filter housing portion 1b by the rear panel 2. The rear panel 2 has a substantially rectangular shape, a plurality of ventilation holes 2a are formed in a matrix, and a fiber sheet on a mesh is pasted on the back surface.

  The rear panel 2 is attached to the rear surface of the housing 1 in which the deodorizing filter 6 and the dust collecting filter 7 are housed, and is completely covered by the rear panel 2 including the deodorizing filter 6 and the dust collecting filter 7. It is.

  The rear panel 2 is supported by hooking a hook 2b from the upper part bent toward the housing 1 to the upper part of the housing 1, and is fixed to the lower part by a locking part 2c.

  In the housing 1, a blower 8 is disposed on the front side of the filter housing portion 1 b with the partition walls 11 and 12 interposed therebetween. The blower 8 includes a fan 81 and a fan motor 82 that drives the fan 81, and the front side is isolated by the partition wall 12. Further, a fan motor 82 is fixed to the front partition 12, and a plurality of ventilation holes communicating with the blower 8 are formed in the rear partition 11. Although the fan 81 is a turbo fan, a propeller fan or a cross flow fan can also be employed, and the type of fan is not particularly limited. In the case of a turbo fan, the thickness is made larger than the diameter of the fan so as to lower the noise level. The fan motor 82 uses a direct current motor with emphasis on the ease of drive control.

  Further, a protective cover is provided on the front side of the filter housing portion 1b so that the humidifying filter 3 and the rotation driving mechanism 9 that rotates the humidifying filter 3 are not directly touched, and an opening through which air passes is formed. Yes.

  In the housing 1, a blow-out passage 13 is formed by partition walls 11 and 12 in an upper portion corresponding to the upper side of the blower 8, and the blow-out passage 13 communicates with a blow-out opening 14 that opens upward. 14 is provided with a wind direction plate 15. On the upper part of the housing 1, there are provided an operation / display unit comprising operation buttons for turning on / off the power and setting operation, a display lamp for displaying the operation state, and the like.

  The wind direction plate 15 is driven by a driving means such as a stepping motor in a predetermined range from the oblique direction or the horizontal direction to the upward direction in order to blow the air flow in the oblique direction or from the horizontal direction to the upward direction.

  As the blower 8 is driven, that is, the fan 81 is rotated by the fan motor 82, external air (indoor air) is introduced from the vent 2 a of the rear panel 2. The introduced air is purified by the deodorizing filter 6 into air having no odor or dust. The purified air is sucked into the central portion of the fan 81 from the vent hole of the partition wall 12 through the ventilation path. The air sucked into the central portion of the fan 81 passes between the fan blades, is discharged from the outer periphery of the fan 81, is guided upward, and is blown out into the outside room by the direction of the air outlet 14 and the wind direction plate 15. .

  A rotatable humidifying filter 3 is disposed in the ventilation path leading from the deodorizing filter 6 and the dust collection filter 7 to the blower 8. Specifically, in the lower part of the housing 1, a water tank 4 that can be attached and detached from one side, and a disk-shaped humidifying filter 3 is disposed above the water tank 4 so as to be rotatable.

  The water tank 4 is connected to one side of the water supply part 4a and the water supply part 4a disposed below the water supply container 5 disposed in the recess 1d of the housing 1, and is inserted into the housing 1 from the insertion part 1c of the housing 1. The water storage portion 4b has a T-shape in plan view, shaft support portions 10 and 10 are held on both sides of the water storage portion 4b, and the humidifying filter 3 attached to the top of the shaft support portions 10 and 10 At the same time, the water storage part 4b can be taken out from the insertion part 1c, and water is supplied to the water storage part 4b from the water supply container 5 through the water supply part 4a in a timely manner, and water is stored at a constant water level.

  The humidifying filter 3 as a filter has water absorption and air permeability, and includes a disk-shaped filter body 31 folded in a zigzag manner and an annular frame body 32 that holds the outer periphery of the filter body 31. A horizontal rotation shaft 33 is provided at the center, and the rotation shaft 33 is rotatably supported by the tops of the shaft support columns 10, 10, so that a part of the circumferential direction is submerged in the water tank 4. It is arranged in a vertical posture so that the lowermost part is submerged, and the water is sucked up to contain moisture. Further, the humidifying filter 3 is configured to be able to be inserted into and removed from the insertion portion 1c from the radial direction together with the water storage portion 4b of the water tank 4 while being supported by the shaft support portions 10, 10.

  The humidifying filter 3 is provided with a submerged portion 3a in which the filter main body 31 is submerged by water that has entered the inside of the frame 32 and a non-submerged portion 3b that is not submerged in the circumferential direction.

  The non-immersed part 3b is provided at a part of the outer peripheral part of the filter main body 31, and the submerged part 3a is provided at the rest of the outer peripheral part of the filter main body 31, and the outer edge of the submerged part 3a has a central angle exceeding two right angles. It is arcuate. Accordingly, the portion of the filter body 31 that includes the submerged portion 3a in the outer peripheral portion has a fan shape in which the central angle exceeds two right angles. On the other hand, the outer edge of the non-water-immersed portion 3 b has a bent line shape that is convex in the radial direction of the filter body 31. Accordingly, the portion of the filter body 31 that includes the non-immersed portion 3b in the outer peripheral portion has a polygonal shape (a pentagonal shape in the present embodiment) whose central angle is less than two right angles. The filter body 31 has a line-symmetric shape with a virtual line connecting the rotation center and the center in the circumferential direction of the non-water-immersed portion 3b in a straight line as a symmetry axis.

  Such a filter main body 31 is formed by cutting a part of the circumferential direction of the outer periphery of a disc-shaped filter material having an appropriate thickness, or by punching a rectangular filter material into a desired shape. The shape is generally D-shaped.

  For this reason, when the circumferential center of the non-water-immersed part 3b is stopped vertically, the filter main body 31 enters a non-water-immersed state. Since the non-water-immersed filter body 31 does not absorb the water in the water tank 4, the filter body 31 is dried, and moisture absorption of the air passing through the filter body 31 is suppressed.

  The frame body 32 is made of a synthetic resin and has an annular shape along the outer peripheral surface of the submerged portion 3 a of the filter body 31. In addition, the frame body 32 is configured such that it can be easily assembled and dismantled manually by a builder or user. For this reason, the manufacturing worker or user can manually assemble the frame body. The filter body 31 can be easily attached to or detached from the 32.

  At the rotation center of the humidifying filter 3, a cylindrical rotation shaft 33 that is orthogonal to the side surface of the filter body 31 is provided. Since the humidification filter 3 is arranged in a vertical posture so that a part of the circumferential direction can be submerged in the water tank 4, the rotary shaft 33 is arranged in a horizontal posture.

  The rotary shaft 33 is rotatably supported on the tops of the shaft column portions 10 and 10 extending upward from the side walls that are spaced apart from each other and spaced apart from the water storage portion 4b. As a result, the humidifying filter 3 supports the rotary shaft 33. It is supported at the center so as to be rotatable in the circumferential direction.

  The humidifying filter 3 has a filter main body 31 mounted in a frame 32, and the non-water-immersed portion 3b is heavier than the water-immersed portion 3a. Similarly, even when the filter main body 31 of the submerged part 3a contains moisture, the non-submerged part 3b is heavier than the submerged part 3a.

  A reed switch 20 is disposed on one side wall of the water tank 4, and a magnet 21 is disposed on one side of the humidifying filter 3. For convenience of detecting the approach / separation of the magnet 21 by the reed switch 20, the user can It is necessary to attach the humidification filter 3 in a state where the one surface on which the three magnets 21 are arranged faces one side wall of the water tank 4.

  The magnet 21 is fixed to one side surface of the frame 32, and rotates and moves in a circular orbit along with the rotation of the humidifying filter 3. Specifically, the magnet 21 is disposed on the non-immersed part 3b side on the imaginary line connecting the rotation center of the filter main body 31 and the circumferential center of the non-immersed part 3b. For this reason, when the magnet 21 is located in the vertical (lowermost part) of the humidification filter 3, the circumferential center of the non-immersed part 3b is also arranged vertically.

  The reed switch 20 is turned on when the magnet 21 approaches the reed switch 20 and turned off when separated. As a result, the reed switch 20 functions as a detector that detects the approach / separation of the magnet 21 with respect to the reed switch 20.

  When the magnet 21 is arranged at the center in the circumferential direction of the switch-on region, the magnet 21, and consequently the center in the circumferential direction of the non-water-immersed portion 3b is arranged vertically (lowermost). In this state, the filter body 31 is not submerged. On the other hand, when the magnet 21 is greatly deviated from the center in the circumferential direction of the switch-on region, at least a part of the submerged portion 3a is submerged and the filter main body 31 is submerged.

  When the air is not humidified (during non-humidifying operation), it is necessary to stop the rotation of the humidifying filter 3 in a state where the filter body 31 is not submerged. Therefore, in order to measure the timing for stopping the rotation, the reed switch 20 and the magnet 21 are used. Is used, and the reed switch 20 is turned on and the rotation of the humidifying filter 3 is stopped when the center in the circumferential direction of the non-immersed part 3b reaches the vertical (lowermost part).

  The rotation drive mechanism 9 includes a roller 91 that contacts the outer peripheral surface of the frame 32 and rotates the humidification filter 3, and an electric motor 92 that is interlocked with the roller 91. Although the filter main body 31 is not disk-shaped, the frame body 32 is annular, so that the roller 91 can contact the outer peripheral surface of the frame body 32 to rotate the humidification filter 3.

  The position where the roller 91 contacts the outer peripheral surface of the frame 32 is a position slightly separated in the circumferential direction opposite to the insertion portion 1c from the uppermost position of the outer peripheral surface of the frame 32, in other words, from the uppermost position. Is also the lower position.

The roller 91 is disposed so as to come into contact with a portion that is separated from the uppermost position of the humidifying filter 3 in the circumferential direction, and the rotation shaft 33 and the rotation center of the roller 91 are disposed in parallel to each other.
For this reason, when the roller 91 is rotated by the operation of the electric motor 92, the humidifying filter 3 rotates clockwise with the rotation of the roller 91. That is, the rotation drive mechanism 9 rotates the humidification filter 3 in the circumferential direction.

  When performing maintenance such as water scale of the humidifying filter 3 and cleaning of the water tank 4, the humidifying filter 3 can be taken out from the insertion part 1 c of the housing 1 together with the water tank 4 in a state where the humidifying filter 3 is attached to the shaft column parts 10, 10 of the water tank 4. It is a form.

  The humidifying filter 3 taken out from the housing 1 is removed from the water tank 4, and the humidifying filter 3 and the water tank 4 alone are removed from the humidifying filter 3 and the water tank 4 to remove dirt and dust attached thereto. Perform cleaning maintenance.

When the maintenance is completed, the humidifying filter 3 is attached to the shaft support portions 10 and 10 of the water tank 4 again.
The form at this time is a state in which the non-immersed part 3b of the humidifying filter 3 is submerged in the water of the water tank 4, that is, the non-submerged part 3b of the humidifying filter 3 is heavier than the submerged part 3a. The humidifying filter 3 is rotated by its own weight so that becomes vertical, and the non-water-immersed part 3 b is vertically immersed in the water of the water tank 4.

  When the non-immersed portion 3b of the humidifying filter 3 is vertically mounted on the water tank 4, and inserted into the housing 1 from the insertion portion 1c, the peripheral surface of the roller 91 comes into contact with the outer peripheral surface of the humidifying filter 3, It can be started.

When the weight of the submerged part 3a and the non-submerged part 3b of the humidifying filter 3 is equal, or when the submerged part 3a is heavier than the non-submerged part 3b, which position (angle) the non-submerged part 3b of the humidifying filter 3 is at. Not sure. Therefore, when the non-immersed part 3b of the humidifying filter 3 is separated from the vertical direction in the circumferential direction when mounted in the housing 1, in other words, the submerged part 3a is surrounded by the water in the water tank 4 or slightly from the water. If it is separated in the direction, when the non-humidifying operation is started in this state, the humidifying filter 3 rotates until the vertical of the non-water-immersed portion 3b is detected by the magnet 21 and the reed switch 20, in other words, non-water-immersed. The part 3b rotates to the position where the water tank 4 is submerged. At this time, the submerged portion 3 a of the humidifying filter 3 passes through the water in the water tank 4, so that the filter main body 31 is in a state of absorbing the water in the water tank 4.
When the non-humidifying operation is started in this state, the air in the ventilation path passes through the humidifying filter 3, so that the air sucks the moisture sucked into the filter main body 31 and is released into the room. The environment gets worse and uncomfortable.

  In the present invention, when the non-humidifying operation is started, air is released into the room without containing moisture, so that a comfortable space can be created without deteriorating the indoor environment.

  In addition to the above description, when the non-humidifying operation is started, the rotation of the blower 8 is stopped for a certain period of time and air is sucked into the filter main body 31 in order to eliminate the release of air containing moisture into the room. You may leave it until the moisture in which it was dried is dried.

  In addition, between the blower outlet 14 and the air blower 8, the ion generator 22 which generate | occur | produces positive / negative ion simultaneously or individually is arrange | positioned. When the ion generator 11 is driven, ions are released from the ion generator 22 into the air that is directed from the fan 81 to the blowout port 14, and the purified air and the humidified air further contain the ions. 14 is blown into the room.

  FIG. 5 is a block diagram showing a main configuration related to the operation of the air purifier. The overall operation of the air cleaner is controlled by the control unit 23. Connected to the control unit 23 are sensors such as a temperature sensor 24, a humidity sensor 25, a dust sensor 26, and an odor sensor 27, and drive circuits 82a and 92a for the reed switch 20, the fan motor 82 and the electric motor 92, respectively. The temperature sensor 24 detects the temperature of indoor air. The humidity sensor 25 detects the humidity of indoor air. In general, the temperature sensor 24 and the humidity sensor 25 are integrated sensors. The dust sensor 26 includes a light emitting element and a light receiving element, and detects particles such as dust floating in the indoor air. The odor sensor 27 is a semiconductor gas sensor that utilizes a change in resistance value when gas is adsorbed on the surface of a sensor made of a metal oxide semiconductor, and detects odor components in indoor air.

  That is, the dust sensor 26 and the odor sensor 27 function as a dirt detector that detects the degree of air dirt. Detection values from the temperature sensor 24, the humidity sensor 25, the dust sensor 26, and the odor sensor 27 are output to the control unit 23.

  In addition, various operation buttons 28 a and various display lamps 28 b constituting the operation / display unit 28 are connected to the control unit 23. As the operation button 28a, a power button for turning on / off the power, an air purification setting button for setting the operation of the air purification function, a humidification setting button for setting the operation of the humidification function, and an operation setting of the humidification function A non-humidification setting button for not performing ionization, an ion emission button for turning on / off ion emission, and the like. Each time the air purification setting button is pressed, the air purification operation mode is switched such as automatic air volume, low air volume, and high air volume. Each time the humidification setting button is pressed, the humidification operation mode is switched, such as humidification automatic, humidification weak, humidification strong, or humidification off. An input from the operation button 28 a according to the user's operation is output to the control unit 23.

  As the indicator lamp 28b, a power indicator lamp that indicates ON / OFF of the power source according to the operation of the power button is turned on / off, and an air purification operation mode that indicates the air purification operation mode according to the operation of the air purification setting button is lit. A display lamp, a humidifying operation mode display lamp that indicates the humidifying operation mode according to the operation of the humidifying setting button, and an ion emission display lamp that indicates whether or not the ion emission according to the operation of the ion releasing button is turned on / off. A humidity display lamp that displays the current humidity as a level, a water supply display lamp that urges replenishment of water to the water supply tank 16 by lighting, and the like are included.

The display lamp 28b is turned on / off according to a command from the control unit 23. Among them, the display of the humidity display lamp is based on the detection value from the humidity sensor 25. The display of the water supply display lamp is made according to the detection output from the water level detection switch 29 of the water tank 4.
Here, an example of driving modes of the wind direction plate 15, the blower 8, and the ion generator 22 by the control unit 23 is listed below.

  The control unit 23 adjusts the rotational speed of the blower 8, that is, the fan motor 82, based on a detection value from at least one of the dust sensor 26 and the odor sensor 27. More specifically, when the air purification operation is performed in the humidification cut mode and the air volume automatic mode, the rotational speed of the fan motor 82 is stepped in accordance with the detection values from the dust sensor 26 and the odor sensor 27. Switch to. For example, if it is determined from the detected value that the air is dirty, the fan motor 82 is rotated at a high rotational speed to cause the air to flow with a large air volume, and the air purifying function is positively exhibited. If it is determined from the detected value that the air has become clean, from the viewpoint of suppressing noise and power consumption, the fan motor 82 is switched to a rotation at a low rotation speed to cause the air to flow with a small amount of air and the air purification function at a low level. maintain. If it is determined that the air is again contaminated, the fan motor 82 is switched to rotation at a high rotation speed. This is repeated. This makes it possible to clean indoor air cleanly.

  The control unit 23 adjusts the humidification amount, that is, the rotation speed of the fan motor 82 or the rotation speed of the humidification filter 3 based on the detection value from the humidity sensor 25. Specifically, when the humidification operation is performed in the humidification automatic mode, for example, when the target humidity is set to 60%, if the detected value from the humidity sensor 25 is 60% or more, the humidification filter If the humidity is less than 60%, the number of rotations of the humidification filter 3 is decreased to increase the humidification efficiency. As a result, the indoor air can be adjusted to the set target humidity.

  In addition, although the form of the Example demonstrated above demonstrated the air cleaner provided with the deodorizing filter 6 and the dust collection filter 7, it is good also as a humidifier which does not have the deodorizing filter 6 and the dust collection filter 7. The humidifier includes a housing 1, a humidifying filter 3 as a filter, a water tank 4, a blower 8, a rotation drive mechanism 9, and the like.

  Moreover, in embodiment mentioned above, although the non-water-immersed part 3b was provided in one place of the circumferential direction of the humidification filter 3, and the remainder was made into the water-immersed part 3a, the non-water-immersed part 3b is other than two places of the circumferential direction, for example. It may be provided.

  Further, the humidifying filter 3 as the filter of the embodiment described above has a configuration including the non-circular filter main body 31 and the annular frame 32, but the humidifying filter 3 eliminates the frame 32, It is good also as a structure which the rotation drive mechanism 9 rotates the rotating shaft 33 of the filter main body 31 kept shape.
