First Embodiment
Hereinafter, a first embodiment of the present invention will be described based on the drawings. In the present embodiment, an air cleaner with a humidifying function will be described as an example of an electric device provided with a ventilation path. FIG. 1 shows a side cross-sectional view of an air cleaner according to the present invention.

  As shown in FIG. 1, in the air cleaner of the present embodiment, an air inlet 2 is provided on the back of the device body 1, and an air outlet 3 is provided on the top rear of the device body 1. A ventilation passage 4 (indicated by an arrow in the drawing) extending from the air suction port 2 to the air blowout port 3 is formed inside the device body 1. A filter 5, a humidifying device 6, and a blower 7 are interposed in the air passage 4 sequentially from the upstream side in the blowing direction W (the direction of the arrow in the figure).

  In the present embodiment, a sirocco fan is used as the blower 7. A suction panel 8 having a plurality of vent holes is detachably attached to the air suction port 2. In the present invention, the upstream side or the downstream side means the upstream side or the downstream side of the blowing direction W, respectively.

  The filter 5 of the present embodiment has a configuration in which the deodorizing filter 9 and the dust collecting filter 10 are integrated into one unit. As the deodorizing filter 9, it is possible to use, for example, a porous material such as activated carbon filled in a bag having air permeability, or a non-woven fabric. In addition, as the dust collection filter, for example, a known High Efficiency Particulate Air (HEPA) filter can be used.

  An ion generator 11 is installed in the air passage 4 on the upstream side of the filter 5, that is, in the space between the suction panel 8 and the filter 5. The ion generator 11 includes an induction electrode and a discharge electrode, and when a high voltage is applied between the induction electrode and the discharge electrode, corona discharge occurs. The corona discharge generates positive and / or negative ions.

Here, positive ions are cluster ions in which a plurality of water molecules accompany hydrogen ions (H ⁺ ) and are represented as H ⁺ (H ₂ O) _m (m is an arbitrary natural number). The negative ion is a cluster ion in which a plurality of water molecules are attached around an oxygen ion (O ₂ ⁻ ), and is expressed as O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number).

In addition, if release of positive ions and negative ions in the bipolar ion, and H ⁺ is a positive ion in the air (H ₂ O) _{m (m} is an arbitrary natural number), O ₂ is negative ion ^- (H ₂ O) _n (n is an arbitrary natural number) generates approximately equal amounts, so that both ions float around airborne fungi, viruses, odor components, etc., and active species produced at that time These can be removed by the action of hydroxyl radicals (.OH) and hydrogen peroxide (H ₂ O ₂ ).

  The ion generator 11 is not limited to the ion species of the present embodiment, and may generate other ion species. For example, it may generate negative ions. Ionizable species that kill or inactivate viruses are preferred.

  The humidifying device 6 includes a disk-shaped humidifying filter 12, a water receiving tray 13, a holding frame 14 for holding the humidifying filter 12, and a drive gear 15 driven by a motor. A driven gear is attached along the outer periphery of the holding frame 14, and the driven gear and the drive gear 15 mesh with each other. As the humidification filter 12 rotates, the part immersed in the water receptacle 13 sequentially moves in the circumferential direction to absorb water, and the entire humidification filter 12 becomes in a state containing water. As a result, the air having passed through the humidification filter 12 is humidified. On the other hand, when the humidifying filter 12 is not rotating, the air passing through the humidifying filter 12 hardly absorbs moisture.

  When the operation of the air cleaner having the above configuration is started, the blower 7 is driven, and positive ions and negative ions are generated from the ion generator 11. Since the ion generator 11 is directly installed in the air passage upstream of the filter 5, the ions generated by the ion generator are supplied to the upstream side of the filter. The ions destroy bacteria and odorous components attached to the filter 5 and can maintain good hygiene of the air purifier over a long period of time.

Second Embodiment
FIG. 2 is a side sectional view showing the air cleaner of the second embodiment. The present embodiment differs from the first embodiment in that a filter in which a deodorizing filter and a dust collecting filter are separately formed is installed in a space surrounded by both filters. The other configuration is the same as that of the first embodiment.

  Specifically, filters individually manufactured using the deodorizing filter as the first filter 16 and the dust collection filter as the second filter 17 are used. In the four passages, the first filter 16 is on the upstream side and the second filter 17 is on the downstream side, and both are installed at an interval. The ion generator 11 is installed in the inter-filter space S formed between the first filter 16 and the second filter 17.

  When the operation of the air cleaner having the above configuration is started, the blower 7 is driven, and positive ions and negative ions are generated from the ion generator 11. Since the ion generator 11 is directly installed in the inter-filter space S, the ions generated by the ion generator 11 are supplied to the inter-filter space S.

  And the 1st filter 16 and the 2nd filter 17 serve as resistance, and it can equalize, raising ion concentration in air in space S between filters. As a result, it is possible to effectively inactivate by means of ions molds and bacteria particularly attached to dust attached to the downstream second filter, and to decompose odor components.

  As explained above, when installing the ion generator 11 between the 1st filter 16 and the 2nd filter 17, it is desirable to distribute a dust collection filter as the 2nd filter 17 by the side of the lower stream. As a result, bacteria and odor components attached to the dust deposited on the filters 16 and 17 can be effectively destroyed, and good hygiene of the air cleaner can be maintained for a longer period of time.

Third Embodiment
FIG. 3 is a side sectional view showing the air purifier according to the third embodiment, and FIG. 4 is a schematic sectional view taken along the line A-A showing the air passage of FIG. In the present embodiment, as a method of supplying ions to the inter-filter space, an ion generation chamber for generating ions by the ion generator is provided in the vicinity of the ventilation passage in the portion where the inter-filter space exists, and the ions generated in the ion generation chamber The second embodiment differs from the second embodiment in that the space between the filters is supplied through the ion generation chamber and the ion supply path. The other configuration is the same as that of the second embodiment.

  In the present embodiment, the ion generation chamber 18 is provided in contact with the upper wall of the air passage 4 in the portion where the inter-filter space S exists (abbreviated as the inter-filter space portion) in the device body 1. The ion generator 11 is accommodated in the ion generation chamber 18. Further, the ion supply passage 19 is formed from the ion generation chamber 18 to the periphery of the left and right side walls of the air passage 4 in the inter-filter space S portion.

A plurality of ion supply holes 20 are bored in the upper wall and both side walls of the air passage 4 in the inter-filter space S, and ions generated in the ion generation chamber 18 are transferred from the ion generation chamber 18 to the ion supply passage 19. It diffuses and is supplied to the inter-filter space S through the ion supply holes 20. According to the above configuration, since the ion generating device 11 is installed outside the ventilation passage 4, there is no possibility that the ion generating device 11 becomes the resistance of the air flowing through the ventilation passage 4. Adhere
Dust amount can be significantly reduced.

  In the present embodiment, only the ion supply holes 20 are formed in the ion generation chamber 18 and the ion supply path 19 connected thereto, but in addition to this, for example, as shown in FIGS. It is also possible to form an intake passage 21 in the chamber 18. That is, the pressure in the ventilation path 4 in which the ion supply holes 20 are opened is brought into a negative pressure state lower than the atmospheric pressure by driving the blower 7.

  Therefore, if the intake passage 21 is provided in the ion generation chamber 18, air flows from the intake passage 21 toward the ion supply hole 20, so that ions can be smoothly supplied to the inter-filter space S. This makes it possible to further increase the ion concentration in the inter-filter space S.

  The intake passage 21 can be formed so as to connect the ventilation passage 4 on the downstream side of the blower 11 as shown in FIG. 5 with the ion generation chamber 18, and as shown in FIG. It is also possible to form so as to connect the outside of the main body 1 and the ion generation chamber 18. However, when air is taken in from the outside of the device body 1, it is preferable to dispose the dust collection filter 21 a in the intake passage 21.

  As a method of supplying the ions generated by the ion generator 11 to the upstream side of the filter 5 (or the second filter 17), the inside of the air passage 4 on the upstream side of the filter 5 (or the second filter 17) as described above. In addition to installing the ion generating device 11 in the vicinity thereof, the ion generating device 11 is installed on the downstream side of the blower 7 in the air passage 4, and a branch path is provided on the downstream side of the ion generating device 11. The air containing ions can be supplied to the upstream side of the filter 5 (or the second filter 17) by connecting the branch path to the upstream side of the filter 5 (or the second filter 17).

  However, in the above configuration, the concentration of ions contained in the air discharged from the air outlet can be increased, while the concentration of ions contained in the air supplied to the upstream side of the filter 5 (or the second filter 17) is constant It will be difficult to raise it. Therefore, in order to release air having a high ion concentration to the outside and to enhance the filter cleaning effect, the ion generator 11 is installed downstream of the blower 7 and the filter 5 (or the second filter 17). Another ion generator 11 may be installed in the ventilation path 4 on the upstream side of or in the vicinity thereof.

Fourth Embodiment
As described in JP 2012-159232A as an electric device conventionally provided with a ventilation path such as an ion generator, an air cleaner, a dehumidifier, a humidifier, a blower or an air conditioner, There is known an air purifier which is mounted and emits ions together with air to inactivate mold, bacteria and the like suspended in the air.

  In the above-mentioned patent documents, the ion generating device is installed on the downstream side of the air blower interposed in the air passage, and a branch path is provided on the downstream side of the ion generator, and the branch path is connected on the upstream side of the air blower. To supply air containing ions to the upstream side of the air blower, thereby making it possible to inactivate mold, bacteria, etc. adhering to the inside of the air passage (especially air blower) by one ion generator. There is.

  However, in the above configuration, in order to supply air having a high ion concentration to the upstream side of the blower, it is necessary to close the air inlet and the air outlet of the air passage and drive the blower. That is, while the air having a high ion concentration was supplied to the upstream side of the blower, it was necessary to stop the air cleaning operation.

  Therefore, in the present embodiment, even with one ion generating device, air having a high ion concentration can be discharged to the outside of the device body, and the ion concentration can be increased upstream of the blower without stopping the operation of the electric device. An object is to provide an electrical device capable of supplying high air.

  In order to achieve the above object, in the present embodiment, the electric device includes an air passage, an air blower interposed in the air passage, and an ion generating device for supplying ions to the air passage. The ion generating device includes a first position for supplying ions to the downstream region downstream of the blower and a second position for supplying ions to the upstream region upstream of the blower in the air passage. It is characterized in that it is switchably movable.

  According to the above configuration, by switching the position of the ion generating device to the first position and the second position without stopping the operation of the electric device, the air having a high ion concentration is released to the outside from the air outlet. Alternatively, air having a high ion concentration can be supplied to the upstream region to inactivate molds, bacteria, and the like attached in the air passage.

  In order to switch the ion generator to the first position and the second position, for example, the ion generator can be slid. Further, regarding the structure of the air passage of the electric device, a part of the wall surface constituting the downstream region is a partition separating the downstream region and the upstream region, the ion generator is attached to the partition, and the ion generator is attached. It is also possible to provide the bulkhead portion in a reversible manner.

That is, although the wiring for supplying electric power is necessary for the ion generating device, according to the above configuration, the moving range of the ion generating device is only by reversing the partition portion to which the ion generating device is attached. Since the number is very limited, the wiring process can be easily performed. Therefore, while having a simple structure, the ion generating device can be reliably set in the first position and the
It can be switched and moved to two positions.

  Hereinafter, a fourth embodiment of the present invention will be described based on the drawings. In the present embodiment, an air cleaner with a humidifying function will be described as an example of an electric device provided with a ventilation path. 7 and 8 are side sectional views of the air cleaner according to the present invention, FIG. 7 shows the ion generator in the first position, and FIG. 8 shows the ion generator in the second position. It shows each. FIG. 9 is a schematic cross-sectional view taken along line B-B showing the air passage of FIG.

In the present invention, the upstream side or the downstream side means the upstream side or the downstream side of the blowing direction W, respectively.

  In the present embodiment, filters made separately are used as the first filter 16 as the deodorizing filter and as the second filter 17 as the dust collection filter. Then, in the air passage 4, with the first filter 16 on the upstream side and the second filter 17 on the downstream side, both are installed at an interval. An inter-filter space S is formed between the first filter 16 and the second filter 17. Then, an ion generation chamber 18 for generating ions by the ion generator 11 is provided in the vicinity of the air passage 4 in the portion where the inter-filter space S exists.

As the deodorizing filter, for example, a porous material such as activated carbon, which is filled in a bag having air permeability, or a non-woven fabric can be used. In addition, as the dust collection filter, for example, a known High Efficiency Particulate Air (HEPA) filter can be used.

Ion supply paths 19 are formed from the ion generation chamber 18 to the periphery of the left and right side walls of the air flow path 4 in the inter-filter space S portion. A plurality of ion supply holes 20 are bored in the upper wall and both side walls of the air passage 4 in the inter-filter space S, and ions generated in the ion generation chamber 18 are transferred from the ion generation chamber 18 to the ion supply passage 19. It diffuses and is supplied to the inter-filter space S through the ion supply holes 20.

The ion generator 11 includes an induction electrode 22 and a discharge electrode 23. When a high voltage is applied between the induction electrode 22 and the discharge electrode 23, corona discharge occurs. Application of a positive high voltage generates positive ions, and application of a negative high voltage generates negative ions.

Here, positive ions are cluster ions in which a plurality of water molecules accompany hydrogen ions (H ⁺ ) and are represented as H ⁺ (H ₂ O) _m (m is an arbitrary natural number). The negative ion is a cluster ion in which a plurality of water molecules are attached around an oxygen ion (O ₂ ⁻ ), and is expressed as O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number).

In addition, if release of positive ions and negative ions in the bipolar ion, and H ⁺ is a positive ion in the air (H ₂ O) _{m (m} is an arbitrary natural number), O ₂ is negative ion ^- (H ₂ O) _n (n is an arbitrary natural number) generates approximately equal amounts, so that both ions float around airborne fungi, viruses, odor components, etc., and active species produced at that time These can be removed by the action of hydroxyl radicals (.OH) and hydrogen peroxide (H ₂ O ₂ ).

  The ion generator 11 is not limited to the ion species of the present embodiment, and may generate other ion species. For example, it may generate negative ions. Ionizable species that kill or inactivate viruses are preferred.

  The humidifying device 6 includes a disk-shaped humidifying filter 12, a water receiving tray 13, a holding frame 14 for holding the humidifying filter 12, and a drive gear 15 driven by a motor. A driven gear is attached along the outer periphery of the holding frame 14, and the driven gear and the drive gear 15 mesh with each other. As the humidification filter 12 rotates, the part immersed in the water receptacle 13 sequentially moves in the circumferential direction to absorb water, and the entire humidification filter 12 becomes in a state containing water. As a result, the air having passed through the humidification filter 12 is humidified. On the other hand, when the humidifying filter 12 is not rotating, the air passing through the humidifying filter 12 hardly absorbs moisture.

  As shown in FIG. 7, a part of the wall surface constituting the downstream region R1 is a partition wall 24 that separates the downstream region R1 from the upstream region R2. And the ion generator 11 is attached to this partition 24 so that switching movement is possible. The upstream region R2 also includes an ion generation chamber communicating with the air passage, in addition to the air passage. In the present embodiment, the partition wall 24 separates the downstream region R1 and the ion generation chamber 18 as the upstream region.

  As shown in FIG. 10, in the present embodiment, a part of the partition wall 24 is cut out in the form of the ion generating device 11 to form the cut-out portion 25, and the ion generating device 11 is incorporated into the cut-out portion 25. The drive motor 26 is disposed concentrically with the central axis C. By driving the drive motor 26, the ion generator 11 itself can be turned upside down.

  In the ion generator, the aforementioned discharge electrode 23 and dielectric electrode 22 are attached to the substrate 27. The dielectric electrode 22 is an elongated plate, and a plurality of through holes 28 are formed at intervals. Both ends of the dielectric electrode 22 are bent to form legs 29. Thereby, the through hole 28 is fixed at a position separated from the substrate 27 by a predetermined distance.

  Discharge electrode 23 projects from substrate 27 toward through hole 28 so as to be located at the center of through hole 28, and the needle-like tip of discharge electrode 23 is within the thickness range of through hole 28 of dielectric electrode 22. Adjusted to be located at When a high voltage is applied between the dielectric electrode 22 and the discharge electrode 23, corona discharge occurs at the tip of the needle-like discharge electrode 23. In the figure, reference numeral 30 denotes a wire for supplying power to the ion generator.

  In addition to the above embodiment, a part of the partition is cut out to form a cutout, and a partition having a shape corresponding to the cutout is rotatably provided around the central axis, and the ion generator is fixed to one surface of the partition. You may do so.

  When the operation of the air cleaner having the above configuration is started, the blower 7 is driven, and positive ions and negative ions are generated from the ion generator 11. When the ion generator 11 is in the first position, as shown in FIG. 7, ions are generated in the downstream region R1 and air having a high ion concentration is blown out from the air outlet 3. On the other hand, when the ion generator 11 is at the second position, as shown in FIG. 8, ions are generated in the ion generation chamber 18 and air having a high ion concentration is supplied to the inter-filter space S.

  According to the above configuration, the first filter 16 and the second filter 17 serve as resistances, and the flow velocity of air in the inter-filter space S is relaxed. Therefore, the ion concentration in the air in the inter-filter space S can be made uniform while being increased. As a result, it is possible to effectively inactivate molds and bacteria attached to the dust particularly attached to the downstream side second filter 17 by the ions, and to decompose the odor component.

Further, since the ion generating device 11 is installed outside the ventilation passage 4, there is no possibility that the ion generating device 11 becomes resistance of the air flowing through the ventilation passage 4, and the amount of dust attached to the ion generating device 11 Can be significantly reduced.

  The ion generator 11 includes the needle-like discharge electrode 23 as described above. If dirt adheres here, ion generation efficiency will fall. Therefore, in the present embodiment, as shown in FIG. 11, the ion generating device 11 is configured to use the configuration in which the first position and the second position are switched and moved by the rotation of the ion generating device 22. It is also possible to install the cleaning member 31 such as a brush or the like so as to contact the discharge electrode 23 when it rotates so as to clean the discharge electrode 23.

  Further, in the present embodiment, the human sensor 32 and the light sensor 33 for grasping the situation around the device body 1 are provided, and the switching movement of the ion generator 11 is controlled by the output signals of these sensors. . Specifically, it is configured to include at least one of a human sensor and an optical sensor, and a control unit that detects an output signal of the sensor and controls switching movement of the ion generator.

The control unit is constituted by a microcomputer, and when neither the human detection by the human sensor nor the light detection by the optical sensor is sensed, the ion generator is at the second position, and at least the human sensor detects a human The ion generator is moved to the first position when light is detected by the light sensor.

Thus, during human activity, air with high ion concentration is released to the outside of the device, and when human activity is not confirmed, air with high ion concentration in the air passage while the operation of the electrical device is continued Can be supplied to inactivate molds, bacteria, etc. adhering to the inside of the air passage. As described above, according to the above configuration, it is possible to automatically determine the presence or absence of a person's activity and efficiently perform sterilization and deodorization in the upstream region. In the present embodiment, both of the human sensor 32 and the light sensor 33 are provided, but only one of them may be used, or control may be performed in combination with another sensor (for example, an infrared sensor etc.) It is also good.

Fifth Embodiment
FIG. 12 is a side sectional view showing an air purifier according to a fifth embodiment. In the present embodiment, the partition wall directly separates the downstream region R1 from the air flow passage on the upstream side of the filter, and as the filter 5, the deodorizing filter and the dust collecting filter are integrally formed as a unit. The point of using a thing is made a difference with a 4th embodiment. The other configuration is the same as that of the fourth embodiment. The above filter may use one type of filter alone.

  In the present embodiment, the ion generation chamber 18 as in the fourth embodiment is not provided, and the partition wall 24 is formed so as to separate the downstream region R1 and the air passage 4 on the upstream side of the filter 5 There is. As described above, the filter 5 of the present embodiment has a configuration in which the deodorizing filter 9 and the dust collecting filter 10 are integrated into one unit. The ion generator 11 directly supplies ions to the air passage 4 on the upstream side of the filter 5 when in the second position. The second position of the ion generator 11 can be arbitrarily set on the upstream side of the blower 7 (for example, between the humidifier 6 and the filter 5 or in the vicinity of the blower 7).

The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the scope of the invention. Specifically, although the embodiment has described the case of the air cleaner with the humidifying function as the electric device, the invention is not limited thereto, and, for example, an ion generator, an air cleaner, a dehumidifier, a humidifier, a blower or an air It may be a conditioner.

Moreover, although the number of the ion generators 11 mounted in the apparatus main body 1 is one in said each embodiment, you may mount the several ion generator 11. FIG. Furthermore, the ion generator 11 generates a discharge noise while being weak at the time of ion generation. Therefore, as shown in FIG. 13, in the ion generator 11, by providing the sound absorbing member 34 on the downstream side of the discharge electrode 23 in the blowing direction W, it is possible to reduce the discharge noise.

The sound absorbing member 34 can use a foam having an open cell structure or a closed cell structure, and can use a non-woven fiber mat or the like excellent in sound insulation. The height of the sound absorbing member is preferably as high as the discharge electrode 23 or slightly higher than the discharge electrode 23. Also, the installation position of the sound absorbing member 34 is preferably closer to the discharge electrode 23, but as shown in FIG. 10, when the plate-like dielectric electrode 22 is used, the dielectric electrode 22 and substrate There is a possibility that the flow of air in the space surrounded by and may be inhibited to reduce the ion generation efficiency.

Therefore, if the dielectric electrode 22 formed in a plate shape is notched around the through hole 28 to form a cutout 35 as shown in FIG. 13, the sound absorbing member 34 can be a discharge electrode 23 (dielectric electrode 22 (dielectric electrode 22). The air flow in the space surrounded by the dielectric electrode 22 and the substrate can be favorably maintained by the notch 35 even if the air conditioner is installed in the vicinity of.

  In the upstream region, in general, a filter and possibly a humidifier are arranged in this order from the upstream side. When the ion generator is at the second position, the ions may be supplied to the upstream side of the filter, or may be supplied between the humidifier and the filter. By supplying ions to the upstream side of the filter, it becomes possible to effectively inactivate mold, bacteria, etc. adhering to the filter, and when ions are supplied between the humidifier and the filter, they adhere to the humidifier. Mold and bacteria can be effectively inactivated.
