FIG. 6 is an external perspective view of the ion generating element 7, and FIG. 7 is an equivalent circuit diagram showing an example of the circuit of the ion generating element 7. As shown in FIGS. 6 and 7, the ion generating element 7 includes a discharge electrode 7a, a discharge electrode hole 7b, a guard 7c, an element body 7d, and an ion emission hole 7e. The discharge electrode 7a is formed of a metal having a pointed end, protrudes from the discharge electrode hole 7b provided in the element body 7d, and is provided so that the pointed end is inside the guard 7c. The ion generating element 7 used in the first embodiment includes two discharge electrodes 7a. From one discharge electrode 7a, positive ions H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and the other discharge. Negative ions O ²⁻ (H ₂ O) _n (n is an arbitrary natural number) are generated from the electrode 7a.

  As shown in FIG. 6, the guard 7c is a plate-like component that is provided integrally with the element body 7d at a predetermined distance from the element body 7d, and emits ions so that the extended axis of the discharge electrode 7a is at the center. Hole 7e is opened. By providing the guard 7c at a position that covers the discharge electrode 7a, it is possible to prevent the discharge electrode 7a from being inadvertently damaged during maintenance and the user from damaging the fingertip or the like.

  As shown in FIG. 7, a terminal 7g is provided in the outer portion of the element body 7d, and receives power supply from, for example, an AC 100V external power source. A circuit that generates high-voltage electricity to be applied to the discharge electrode 7a is housed inside the element body 7d. An electric pulse generated by a circuit including a resistor and a capacitor is converted into a high-voltage electric pulse by a high-voltage transformer 7f, applied to the discharge electrode 7a, and discharged at the tip of the discharge electrode 7a to generate ions. .

  In the first embodiment, the ion generating element 7 is provided in such a posture that the ion emission hole 7e faces the back plate 1b, and ions are mixed in the air sucked from the suction port 3. A control unit 9 that controls the ion generating element 7, the blower 8, and the like is installed in the housing 1 in a space opposite to the air passage 6 c side.

  FIG. 8 is a block diagram showing a control configuration of blower device 10 according to Embodiment 1 of the present invention. The control unit 9 is a microcomputer including a CPU, a ROM, and a RAM, for example. The control unit 9 includes a timer 91 and is connected to the input unit 51, the display unit 52, the ion generating element 7, and the blower 8.

  The input unit 51 includes, for example, an operation mode selection switch, a timer operation selection switch, and the like. By pressing the operation mode selection switch, one of “continuous”, “intermittent”, or “off” is selected. By pressing the timer operation selection switch, a desired operation time is selected. Here, the input unit 51 may further include an operation start / stop switch for the ion generating element, an operation start / stop switch for the fixed timer, a timer time setting unit, and the like.

  When the input unit 51 is operated, the control unit 9 receives an instruction such as operation details from the user, operates the ion generating element 7, the blower 8, and the timer 91 according to the instruction, or causes the display unit 52 to operate the blower 10. May indicate that is driving. Here, examples of the display unit 52 include an LED, a liquid crystal panel, and the like, and set operating conditions, device operating conditions, device abnormal conditions, alarms, and the like are displayed. The display unit 52 may include a notification buzzer.

  The movement of the airflow when the blower 10 configured as described above is operating will be described with reference to FIGS. 4, 5, 9, and 10. In the following description, the state in which air is blown out from the diffusion outlets 2a and 2b is referred to as normal blowing, and the state in which air is blown out from the concentration outlet 4 is referred to as concentrated blowing. FIG. 9 is a conceptual diagram in which the air flow in the case of normal blowing is captured by the IX-IX cross section in FIG. 2, and FIG. 10 is the concept in which the air flow in the case of concentrated blowing is captured by the IX-IX cross section in FIG. FIG.

  For example, when the operation mode selection switch of the input unit 51 is pressed and the operation mode is selected as “continuous”, the control unit 9 energizes the blower 8 and the ion generating element 7 to start operation. In this case, when the timer operation selection switch is pressed and a desired operation time is selected, the time measurement by the timer 91 is started, and the control unit 9 switches the blower 8 and the ion generating element 7 over the selected operation time. Let it run continuously.

  First, the movement of the airflow in the case of normal blowing will be described. In the case of normal blowing, the concentration outlet 4 is closed. The airflow SA sucked from the suction port 3 with the operation of the blower 8 enters the suction side of the blower 8 through the blower passage 6c. The airflow SA passes through the blower 8 and is sent in the direction of the concentration outlet 4, collides with the door 4a, and is divided to pass through the airflow path 6a and the airflow path 6b, respectively, and diffuse as airflow EA1 and airflow EA2. It blows out from blower outlet 2a, 2b. In addition, with the operation of the ion generating element 7, positive and negative ions are generated at the discharge electrode 7a, and the air flow SA sucked from the suction port 3 circulates so as to wrap around the discharge electrode 7a, and contains the positive and negative ions. Enter 8 suction side. Positive and negative ions are released to the outside of the blower 10 and can be attached to and react with the surface of suspended matter in the air to sterilize suspended bacteria in the air and remove odors.

  Next, the movement of the airflow in the case of concentrated blowing will be described. In the case of concentrated blowing, the concentration blowing outlet 4 is opened, and the diffusion blowing outlet 2b is closed by the door 4a. The airflow SA sucked from the suction port 3 with the operation of the blower 8 enters the suction side of the blower 8 through the blower passage 6c. The airflow SA passes through the blower 8 and is blown out as the airflow EA from the concentration outlet 4. In addition, with the operation of the ion generating element 7, positive and negative ions are generated at the discharge electrode 7a, and the air flow SA sucked from the suction port 3 circulates so as to wrap around the discharge electrode 7a, and contains the positive and negative ions. Enter 8 suction side. Positive and negative ions are released to the outside of the blower 10 and can be attached to and react with the surface of suspended matter in the air to sterilize suspended bacteria in the air and remove odors.

  In the case of concentrated blowing, the amount of positive and negative ions delivered in one direction is larger than in the case of normal blowing. Since the air flow is divided into two directions in the case of normal blowing, the amount of ions delivered in one direction in the case of concentrated blowing is approximately twice that in the case of normal blowing. Furthermore, in the case of concentrated blowout, the path from the passage through the blower 8 to the blowout to the outside is short and linear, and there is little contact with the front case 1a etc., so positive and negative ions collide with the front case 1a etc. Thus, the generated positive and negative ions can be fully utilized.

  In the first embodiment, since the air outlet includes the diffusion outlets 2a and 2b for diffusing and blowing out the air and the concentration outlet 4 for concentrating and blowing out the air, the air is blown out in different blowing states. Can do. Moreover, by opening and closing the door 4a provided at the concentration outlet 4, the air flow to be blown out can be made into a concentrated air flow or a diffused air flow, and the blowing state can be changed as necessary. Furthermore, when the air blowing path that sequentially connects the suction port 3, the blower 8, the concentration outlet 4, and the diffusion outlets 2a and 2b is formed and the concentration outlet 4 is closed, By forcibly bending the airflow that has passed through the blower 8 at the front case 1a and the door 4a, the door 4a does not require a special structure, and air can be blown out from the diffusion outlets 2a and 2b. When the concentration outlet 4 is open, there is almost no airflow leakage to the air passage 6a and the air passage 6b, and air can be blown out from the concentration outlet 4.

  In the above description, the door 4a of the concentration outlet 4 is a single sliding door that opens on one side, but may be a double sliding door that is divided and opened on both sides. Moreover, it is good also as a door of a double door type instead of a slide type. Furthermore, it may be a structure that is not a door but a removable cap, in which the cap is removed in the case of concentrated blowing, and the cap is attached in the case of normal blowing.

  In the above description, the diffusion outlets 2a and 2b are divided and provided on opposite side surfaces of the housing 1, but either one may be provided. When the diffusion outlet is provided on one side, the structure may be formed so as to expand in the width direction or the height direction as the air passage approaches the outlet. In this way, the blown airflow can be diffused in various directions like a diffuser. Moreover, although the opening for diffusion has two openings, it may be three or more openings as long as the airflow blown from each opening is directed in different directions. Furthermore, although the concentration outlet 4 is provided in the approximate center of the front case 1a in plan view, the airflow blown out from the concentration outlet 4 is different from the airflow blown out from each diffusion outlet. If it is the structure which goes to, the concentration blower outlet 4 may be provided in another place.

  In the above description, the door 4a of the concentration outlet 4 is manually opened and closed. However, a method is provided in which a rack gear is provided on the door 4a, and a pinion gear meshing with the rack gear is driven by a motor. It may be one that automatically opens and closes by a commonly used method such as a method of opening and closing by driving with a motor and solenoid using a link. When the door 4a is configured to automatically open and close, it is preferable to provide a switch that instructs the operation unit 5 to open and close the door 4a.

  The blower 8 is not limited to the propeller fan shown in the first embodiment, but may be other types of fans such as a turbo fan, a sirocco fan, and a cross flow fan.

  Next, the example which uses the air blower 10 of this invention for storage is demonstrated. FIG. 11 is a conceptual diagram showing the movement of airflow during normal blowing when the air blower 10 according to Embodiment 1 of the present invention is installed in the clothing storage case 11, and FIG. 12 is a diagram illustrating the implementation of the present invention. It is a conceptual diagram which shows the motion of the airflow at the time of concentrated blowing at the time of installing the air blower 10 which concerns on form 1 in the clothes storage. FIG.11 and FIG.12 has shown the state inside the clothing storage 11 seen from the door side which is not shown of the clothing storage 11 to the back side. A blower 10 is installed on the ceiling 11 a inside the clothing storage case 11.

  The case of normal blowing of the blower 10 will be described with reference to FIG. In FIG. 11, the air blower 10 is in a state in which the concentration outlet 4 is closed and the diffusion outlets 2a and 2b are opened. The clothes 12 are hung inside the clothes storage 11, and there is a slight gap between the clothes.

  The air blower 10 has the operation unit 5 and the suction port 3 installed in the depth direction of the clothing storage case 11 and the diffusion outlets 2a and 2b installed in the short direction of the clothing storage case 11 (left and right in the drawing). The suction port 3 is located on the back side of the clothing storage 11 with respect to the operation unit 5. The air flow SA is sucked in from the back side of the clothing storage case 11, and is divided into the internal short direction of the clothing storage case 11 through the diffusion outlets 2a and 2b to become the air flow EA1 and the air flow EA2, respectively. The

  The air current EA1 and the air current EA2 pass through the gap between the clothes 12 and descend to the lowermost part of the clothing storage case 11, respectively. Airflow EA1 and airflow EA2 that have reached the bottom of clothing storage 11 gather at the center along the floor of clothing storage 11 and rise through a gap between clothing 12 and a door or back plate (not shown). Then, it is sucked into the blower 10 again.

  When storing clothes newly removed by the user in such a garment storage 11, it is preferable to switch the air outlet of the blower 10 from the diffusion outlets 2 a and 2 b to the concentration outlet 4. . As shown in FIG. 12, when the outlet is switched to the outlet 4 for concentration, the blower 10 can intensively blow out the air current EA in the direction directly below it to increase the ion concentration intensively.

  The user may hang clothes or the like taken off when he / she goes out of the house at a position where the airflow blown from the concentration outlet 4 of the blower 10 directly hits. In such a case, it is preferable to blow out the airflow from the diffusion outlets 2a and 2b after blowing out the airflow from the concentration outlet 4 for a predetermined time.

  In the above description, the ion generating element 7 generates positive and negative ions, but may generate either positive ions or negative ions. Further, instead of the blower device 10 on which the ion generating element 7 is mounted, a simple blower device on which the ion generating element 7 is not mounted may be used. In the clothes storage 11 or the like, a blower that does not include the ion generating element 7 always generates airflow, so that moisture does not stay and can suppress mold generation and the like.

  Further, instead of the ion generating element 7, an electrostatic atomizer 77 (see FIG. 13) described later that generates charged fine particle water by applying a high voltage to water may be used. Further, a combination of the ion generating element 7 and the electrostatic atomizer 77 may be used. The “charged particle” in the claims of the present application is a collective term including the ions generated by the ion generating element 7 and the charged fine particle water generated by the electrostatic atomizer 77.

  FIG. 13 is a schematic diagram showing the structure of the electrostatic atomizer 77. In FIG. 13, the electrostatic atomizer 77 includes a discharge electrode 77a, a counter electrode 77b, a cooling device 77c for cooling the discharge electrode 77a, and a heat radiating plate 77d for releasing heat generated by the cooling device 77c. Further, between the discharge electrode 77a and the counter electrode 77b, a cooling device drive power source 79 is connected to the high voltage generator 78 and the cooling device 77c.

  The high voltage generation device 78 includes a high voltage generation circuit that outputs electric power supplied from an external power source (not shown) as high voltage electricity. The generated high voltage is applied to the discharge electrode 77a to generate a discharge with the counter electrode 77b.

  The cooling device 77c is a device for cooling the discharge electrode 77a to condense moisture in the air on its surface, and since it is required to be small, a Peltier element is generally used, and in particular, the tip of the discharge electrode 77a is used. Used to cover with water film of condensed water.

  The cooling device drive power source 79 is for supplying direct current electricity to a Peltier element as the cooling device 77c, and generates direct current electricity by receiving power supply from an external power source (not shown). The cooling capacity of the cooling device 77c can be adjusted by the current supplied from the cooling device drive power supply 79, and the cooling capacity increases as the current increases.

  The heat radiating plate 77d radiates heat taken by the cooling device 77c into the air when the discharge electrode 77a is cooled, and is made of a metal such as aluminum having high thermal conductivity.

  In the electrostatic atomizer 77 configured as described above, when a high voltage is applied to the discharge electrode 77a in a cooled and condensed state, a discharge phenomenon occurs between the counter electrode 77b and a discharge occurs at that time. The water film on the surface of the electrode 77a is dispersed in fine water droplets. When a negative high voltage is applied to the discharge electrode 77a, the generated fine water droplets become charged fine particle water having a negative charge due to discharge, and further, hydroxyl radicals and radicals which are active species generated by the discharge. Contains hydrogen oxide. These active species can sterilize airborne bacteria.

  Although not shown, the door 40a and the movable floor 40b are maintained in the state where they are pushed in by the locking mechanism, and when they are pushed again, the locked state is released and the initial concentration outlet 40 is closed. Have a structure that is maintained.

  On the side facing the suction port 3 of the partition wall 70, the air passage walls 63 and 64 are connected upright so as to reach the inner surface of the front case 1 a from the inner surface of the back plate 1 b so as to be connected to the partition wall 70. The air passage walls 63 and 64, the front case 1 a, and the back plate 1 b form an air passage 60 c that is connected to the suction port 3. Similar to the first embodiment, the ion generating element 7 is attached to the air passage 60c. A blower 80 for blowing air in the direction of the ion generating element 7 is installed between the ion generating element 7 and the suction port 3. The airflow SA sucked from the suction port 3 by the blower 80 circulates so as to wrap around the discharge electrode 7a.

  The air passage walls 67 and 68 erected from the back plate 1b and the air passage ceiling 71 are connected to the side of the partition wall 70 facing the diffusion outlet 2a. The air passage walls 67 and 68, the air passage ceiling 71, and the back plate 1b form an air passage 60d connected to the diffusion outlet 2a. Similarly, on the side of the partition wall 70 facing the diffusion outlet 2b, the air passage walls 67 and 69 standing from the back plate 1b and the air passage ceiling 72 are connected. The air passage walls 67 and 69, the air passage ceiling 72, and the back plate 1b form an air passage 60e connected to the diffusion outlet 2b.

  The partition wall 70 on the control unit 9 side is erected from the inner surface of the back plate 1b to the inner surface of the front case 1a. The other three-way partition wall 70 has an opening formed by cutting off the portion on the back plate 1b side, and the air passage 60c, the air passage 60d, and the air passage 60e are connected by these openings.

  Hereinafter, the movement of the airflow when the blower 100 configured as described above is in operation will be described with reference to FIGS. FIG. 19 is a conceptual diagram in which the airflow in the case of concentrated blowing is captured by the XVI-XVI cross section in FIG. 14, and FIG. 20 is a conceptual diagram in which the airflow in the case of concentrated blowing is captured by the XVII-XVII section in FIG.

  First, the movement of the airflow in the case of normal blowing will be described. As shown in FIGS. 16 and 17, in the case of normal blowing, the concentration outlet 40 is closed, and the moving floor 40 b is maintained at almost the same height as the air duct ceiling 71 and the air duct ceiling 72, A space is formed between the back plate 1b and the moving floor 40b. Thus, the 1st ventilation path which connects the suction inlet 3, the air blower 80, and the blower outlets 2a and 2b for diffusion is formed. Further, since the moving floor 40b blocks the inside of the room surrounded by the partition wall 70, the air current does not enter the indoor space above the moving floor 40b. Therefore, the airflow SA sucked from the suction port 3 is blown into the space in the partition wall 70 between the back plate 1b and the moving floor 40b by the blower 80, divided into left and right, and enters the air passages 60d and 60e. Is blown out from the diffusion outlet 2a as an air stream EA21, and the other is blown out from the diffusion outlet 2b as an air stream EA22.

  Next, the movement of the airflow in the case of concentrated blowing will be described. In the case of concentrated blowing, the moving floor 40b is pushed down through the support column 40c connected to the door 40a by pushing the door 40a toward the inside of the blower 100, and is maintained by a locking mechanism (not shown). The air outlet 40 is opened. As shown in FIGS. 18-20, in the state where the movable floor 40b is pushed down, the chamber surrounded by the partition wall 70 is communicated with the air passage 60c. In this state, the 2nd ventilation path which connects the suction inlet 3, the air blower 80, and the concentration blower outlet 40 is formed, and the blower paths 60d and 60e are closed by the wall by the side of the diffusion blower outlets 2a and 2b of the moving floor 40b. The flow of airflow to the diffusion outlets 2a and 2b is prevented. Therefore, the airflow SA sucked from the suction port 3 by the blower 80 is pushed upward above the moving floor 40 b and rises along the inside of the partition wall 70. The airflow EA thus pushed up is blown out to the outside as an airflow EA23 and an airflow EA24 from the gap between the edge of the concentration outlet 40 and the door 40a.

  In the second embodiment, when the concentration outlet 40 is in the closed state, the first air passage described above is formed inside the blower 100, but the door 40a faces the inside of the blower 100. When the concentration air outlet 40 is in the open state, the second air blowing path described above is formed. In this way, the first air passage and the second air passage can be switched by opening and closing the door 40a, and the air outlet can be changed.

  In the second embodiment, as in the first embodiment, in the case of concentrated blowing, the amount of positive and negative ions delivered in one direction is larger than in the case of normal blowing. Since the air flow is divided into two directions in the case of normal blowing, the amount of ions delivered in one direction in the case of concentrated blowing is approximately twice that in the case of normal blowing. Furthermore, in the case of concentrated blowing, after passing through the blower 80, the path from the outside to the outside is short, and it is not rare that ions are absorbed by the blowing path or the like. Is possible.
