Detailed description of the preferred embodiment

Hereinafter, the embodiment of the present invention will be described with reference to the drawings.

(Embodiment 1)

Fig. 1 is a perspective view showing an ion generating apparatus according to a first embodiment of the present invention. Fig. 2 is a schematic view showing the main body of the ion generating apparatus. As shown in FIGS. 1 and 2, the ion generating apparatus includes the first air blowing unit 2 and the ion generating unit 3 in the main body casing 1.

The body casing 1 has a substantially elongated box shape. A substantially square-shaped air inlet 4 is provided on a side surface of the back side of the main body casing 1, and a substantially square-shaped air outlet 5 is provided on a top surface portion of the body casing 1. A wind direction louver 6 is provided at the exhaust port 5.

The first air blowing unit 2 is provided in an air passage between the intake port 4 of the main body casing 1 and the exhaust port 5. The first air blowing unit 2 is formed by a wrap-shaped outer casing 7, a blade 8 which is a centrifugal blower fan provided in the outer casing 7, and a first electric motor 9 that rotates the vane 8. The air 52 sucked from the air intake port 4 into the main body casing 1 is blown toward the exhaust port 5 by the first air blowing unit 2.

Fig. 3 is a schematic view showing a first air blowing unit of the ion generating apparatus according to the first embodiment of the present invention. As shown in Figs. 2 and 3, the outer casing 7 is formed by the suction side surface 10, and the suction side surface 11, the suction side surface 10, and the suction side surface 11 of the suction side surface 11 which are opposed to the suction side surface 10. And the tongue piece is formed opposite to the spiral surface 13.

The suction side surface 10 is provided with a circular suction port 14. The suction port 14 is opposed to the intake port 4. The tongue wrap surface 12 has a tongue portion 15 that projects toward the inside of the outer casing 7. The tongue facing scroll surface 13 is opposed to the tongue scroll surface 12. An air outlet 16 that is surrounded by the suction side surface 10, the suction opposing side surface 11, the tongue scroll surface 12, and the tongue facing scroll surface 13 and opening upward is disposed above the outer casing 7. The ion generating unit 3 is disposed in the air passage 51 between the intake port 4 and the suction port 14.

Next, an example of the ion generating unit 3 will be described as the electrostatic atomizing unit 17. Fig. 4 is a schematic view showing an electrostatic atomization unit of the ion generating apparatus according to the first embodiment of the present invention. As shown in FIG. 4, the electrostatic atomization unit 17 includes a discharge electrode 18, a counter electrode 19, a high voltage application unit 20, a Peltier element 21, and heat dissipation fins 22. Here, the counter electrode 19 is opposed to the discharge electrode 18. The high voltage applying unit 20 applies a high voltage between the counter electrode 19 and the discharge electrode 18 (-5 KV in the first embodiment). The Peltier element 21 is disposed as a cooling portion that cools the discharge electrode 18. The heat sink fins 22 dissipate heat from the Peltier element 21.

The Peltier element 21 is applied with a voltage of about 0.75 to 2.8V. In the first embodiment, the discharge electrode 18 side is cooled to a low temperature, and the heat radiation fin 22 side is heated to a high temperature. Therefore, when the indoor air passing through the air supply path is partially cooled and dew condensation on the discharge electrode 18, charged fine particle water is generated.

As a result, the charged fine particle water is exhausted from the exhaust port 5 shown in Fig. 1 toward the outside of the main body casing 1 together with the dry air, and the hydroxyl radicals in the charged fine particle water react with the odor, thereby being oxidized. Decomposes the odor.

Further, the hydroxyl radical is a radical reactive with a hydroxyl group (hydroxyl group), and the radical has only one electron which should normally be rotated by two groups in one orbit. Therefore, the hydroxyl radical is extremely unstable in electrical terms, and in order to capture the missing electrons from the surrounding atoms or molecules, the oxidizing power is very strong, and the odor is decomposed and removed by the oxidation.

The ion generating apparatus according to the first embodiment is characterized in that, as shown in Figs. 2 and 3, the suction side surface on the upstream side of the tongue portion 15 between the tongue facing scroll surface 13 and the blade 8 is provided. There is a point of the attraction portion 23. The air 52 that is sucked into the main body casing 1 from the intake port 4 through the air intake port 4 passes through the suction port 14 and the air outlet 16 to blow air toward the exhaust port 5. Then, by the air blowing, the attracting portion 23 passes the air 52 sucked from the air inlet 4 into the main body casing 1 through the ion generating portion 3 and is attracted to the inside of the casing 7. Here, as shown in Fig. 3, as the air passage between the flap facing the scroll surface 13 and the vane 8 gradually becomes wider toward the air outlet 16 from the position of the attracting portion 23, the air flowing through the air passage gradually becomes One side widens and flows. In other words, ions generated in the ion generating unit 3 and attracted to the inside of the casing 7 flow while gradually being blown from the attraction portion 23 toward the air outlet 16. As a result, the deviation of the airflow direction from the exhaust port 5 of the ions generated from the ion generating unit 3 is reduced.

Fig. 5 is a schematic view showing a wind direction louver of the ion generating apparatus according to the first embodiment of the present invention. As shown in Fig. 5, a wind direction louver 6 is provided at the exhaust port 5. The wind direction louver 6 includes a louver portion 24 having a substantially flat plate shape, and a shaft portion 25 extending outward from the left end portion and the right end portion of the left and right sides of the main body casing 1. The shaft portion 25 is rotatably attached to the bearing portion 26 of the exhaust port 5. The wind direction from the exhaust port 5 is changed by the shaft portion 25 to an elevation direction from the horizontal direction to the vertical direction.

However, when the wind direction louver 6 is rotated, the air blow in the outer casing 7 shown in Fig. 2 may be disturbed. Thus, the attraction portion 23 is provided on the suction side surface 10. Thereby, since the exhaust port 5 and the attraction portion 12 are separated by a predetermined distance, the disturbing effect of the air blow in the outer casing 7 which occurs when the wind provided to the exhaust port 5 is swirled toward the louver 6 is reduced. That is, the amount of change in the amount of ions attracted by the attracting portion 23 is reduced. Further, the main body casing 1 is provided with a motor (not shown) that rotates the wind to the louver 6, and when the motor automatically rotates the wind to the louver 6, the disturbance of the air blow in the casing 7 increases. More effective. The motor rotates the wind toward the louver 6 in an elevation direction from the horizontal direction to the vertical direction.

Fig. 6 is a schematic view showing the attraction portion of the ion generating apparatus according to the first embodiment of the present invention. As shown in FIG. 6, the attraction portion 23 is formed by the opening portion 27 and the negative pressure generating portion 28 located at the periphery of the opening portion 27. The opening portion 27 is an opening having a substantially square shape, and the tongue located in the outer casing 7 faces the suction side surface 10 between the spiral surface 13 and the vane 8. The opening portion 27 has a predetermined distance from the tongue facing scroll surface 13, and the opening portion 27 and the blade 8 also have a predetermined distance.

The negative pressure generating portion 28 is located on the upstream side 54 of the air blowing direction 53 in the outer casing 7 of the opening portion 27. Further, the negative pressure generating portion 28 is formed by the first protruding portion 29 that protrudes from the suction side surface 10 toward the inside of the outer casing 7. The first projecting portion 29 has an inclined surface 30 that is inclined from the suction side surface 10 toward the inside of the casing 7 from the upstream side 54 of the air blowing direction 53 in the casing 7 toward the downstream side 55.

Specifically, the first protruding portion 29 is formed by the horizontal surface 31, the inclined surface 30, and both side faces 32 of the right triangle. Here, the horizontal surface 31 extends in the horizontal direction from the lower end portion of the opening portion 27 toward the inside of the outer casing 7. The inclined surface 30 extends obliquely from the front end of the horizontal surface 31 toward the suction side surface 10 in the downward direction. The two side faces 32 of the right triangle are connected from the opposite ends of the horizontal plane 31 to the opposite ends of the inclined surface 30, respectively.

That is, a portion of the air flowing between the tabs in the outer casing 7 and the vane surface 13 and the vanes 8 flows along the inner surface of the suction side surface 10, and the front surface of the opening portion 27 is along the inclined surface 30. Airflow. This airflow has a predetermined distance from the opening 27, and flows from the upper end of the inclined surface 30 toward the air outlet 16. That is, a negative pressure region that becomes a negative pressure is generated between the airflow and the opening portion 27, and the ions generated by the ion generating portion 3 are attracted from the opening portion 27 by the negative pressure region.

Further, the ions attracted by the airflow flowing from the upper end of the inclined surface 30 toward the air outlet 16 by a predetermined distance from the opening 27 are blown by the airflow from the exhaust port 5 shown in Fig. 1 . That is, since it is considered that the ions have a distance from the suction side surface 10 and are blown out from the exhaust port 5 by the flowing air flow, the reduction of ions caused by charging to the suction side surface 10 can be suppressed.

Further, as shown in Fig. 2, the suction opposing side surface 11 is parallel to the suction side surface 10. Therefore, the distance between the upper end of the inclined surface 30 and the suction opposing side surface 11 becomes shorter than the distance between the lower end of the inclined surface 30 and the suction opposing side surface 11, and the gas flow velocity from the upper end of the inclined surface 30 toward the blowing outlet 16 becomes faster. That is, since the negative pressure region between the air current and the opening portion 27 becomes larger due to the degree of negative pressure, ions generated by the ion generating portion 3 are easily attracted from the opening portion 27.

(Embodiment 2)

Fig. 7 is a schematic view showing an attraction portion of the ion generating apparatus according to the second embodiment of the present invention. In the second embodiment of the present invention, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted, and only the differences will be described.

As shown in Fig. 7, the difference between the second embodiment of the present invention and the first embodiment is as follows. On the downstream side 55 of the air blowing direction 53 in the casing 7 (second drawing) of the first projecting portion 29, two second projecting portions 33 projecting from the suction side surface 10 toward the inside of the casing 7 are provided. Further, the second projecting portion 33 has two vertical faces 34 extending from the upstream side 54 of the air blowing direction 53 in the casing 7 toward the downstream side 55 from the downstream end portion 30a of the inclined surface 30 in the air blowing direction 53 in the casing 7. The vertical surface 34 is located at a position parallel to the suction side surface 10 and sandwiching the opening portion 27.

Specifically, the second projecting portion 33 extends from both ends of the horizontal surface of the first projecting portion 29 toward the downstream side 55 of the air blowing direction 53 in the casing 7 . The vertical surface 34 is a surface of the second protruding portion 33 that faces the suction opposing side surface 11 (second drawing). The vertical surface 34 is coupled to the inclined surface 30 of the first protruding portion 29 and extends to the downstream end portion 27a of the opening portion 27. Further, the opening portion 27 is located between the two second protruding portions 33.

That is, a portion of the air flowing between the tabs in the outer casing 7 shown in FIG. 2 opposite the scroll surface 13 and the vanes 8 flows along the inner surface of the suction side surface 10, and is formed by the seventh figure. The airflow flowing along the inclined surface 30 in front of the opening portion 27 is shown. One of the air flows flows along the vertical faces 34 of the two second projections 33, and the airflow flowing between them also has a predetermined distance from the opening 27, and flows from the upper end of the inclined surface 30 toward the air outlet 16. Here, since the suction opposing side surface 11 shown in Fig. 2 is parallel to the suction side surface 10, the distance between the vertical surface 34 and the suction opposing side surface 11 becomes shorter than the distance between the lower end of the inclined surface 30 and the suction opposing side surface 11. . As a result, the airflow passing through the vertical surface 34 toward the air outlet 16 becomes faster. That is, by the two air currents along the vertical plane 34 of the two second protruding portions 33 shown in Fig. 7, the airflow facing the opening portion 27 positioned therebetween is also faster. As a result, the negative pressure region between the airflow to the opening portion 27 and the opening portion 27 is increased in the negative pressure region, so that the ions generated from the ion generating portion 3 can be attracted from the opening portion 27.

Further, as shown in Fig. 7, the two surfaces extending from the upstream side 54 of the first projecting portion 29 from the upstream side 54 of the air blowing direction 53 toward the downstream side 55 are the two side faces of the second projecting portion 33. That is, the airflow along the both side faces 32 of the first projecting portion 29 is directed toward the air outlet 16 along both side faces 35 of the second projecting portion 33. That is, the airflow along the both side faces 32 of the first projecting portion 29 can be prevented from being directed toward the opening portion 27 by the second projecting portion 33.

Further, the vertical surface 34 extends to the downstream end portion 27a of the opening portion 27 in the air blowing direction in the casing 7. Specifically, the vertical surface 34 is located from the upstream side end portion to the downstream side end portion 27a of the opening portion 27 in the air blowing direction 53 in the outer casing 7.

Further, the length 30b of the airflow direction in the outer casing 7 of the inclined surface 30 is longer than the length 29a of the first projecting portion 29 which protrudes from the inner surface of the suction side surface 10a toward the inside of the casing 7. Specifically, the inclined surface 30 is inclined from the suction side surface 10 toward the inside of the casing 7 as the upstream side 54 of the air blowing direction 53 in the casing 7 faces the downstream side 55. Here, the angle of the suction side surface 10 and the inclined surface 30 inclined from the suction side surface 10 is an acute angle.

That is, a portion of the air flowing between the wrap surface 13 and the vane 8 in the outer casing 7 flows along the suction side surface 10, and flows from the front surface of the opening portion 27 along the inclined surface 30. Here, since the angle of the suction side surface 10 and the inclined surface 30 inclined from the suction side surface 10 is an acute angle, generation of turbulent flow is suppressed.

(Embodiment 3)

Fig. 8 is a schematic view showing an ion generating apparatus according to a third embodiment of the present invention, and Fig. 9 is a perspective view showing the ion generating apparatus. In the third embodiment of the present invention, the same components as those in the first and second embodiments are denoted by the same reference numerals, and the description thereof will be omitted, and only the differences will be described.

In the ion generating apparatus according to the third embodiment of the present invention shown in Figs. 8 and 9, the dehumidifying unit 36 is provided in the main body casing 1, and the dehumidifying unit 36 is winded between the intake port 4 and the first blower unit 2. Road 56 is dehumidified.

The dehumidifying portion 36 includes a dehumidifying rotor 39 having a moisture absorbing portion 37 and a wet portion 38, and a moisture absorbing path 40. The moisture absorption path 40 has a wetted portion 38 of the dehumidification rotor 39, a heater 41 provided on the upper side of the wetted portion 38, a heat exchanger 42 provided on the lower side of the wetted portion 38, and moisture absorption. The second air blowing portion 43 in which the air in the path 40 circulates. Moreover, the moisture absorption path 40 is independently used as an air passage in the body casing 1. Further, a moisture absorbing portion 37 of the dehumidification rotor 39 is provided in the air passage 56 between the intake port 4 and the first air passage 2. More specifically, as shown in Fig. 9, the ion generating apparatus has an exhaust port 5 above the main body casing 1, and a receiving tray 44 is detachably provided below the front surface of the main body casing 1.

Further, as shown in Fig. 8, a dehumidification rotor 39 having a moisture absorption portion 37 and a moisture diffusion portion 38 is rotatably disposed in the main body casing 1. The dehumidification rotor 39 is rotationally driven by a motor 45.

Further, in the front of the main body casing 1, as shown by an arrow A in Fig. 8, the indoor air sucked from the intake port 4 of the main body casing 1 is provided after passing through the moisture absorbing portion 37 of the dehumidifying rotor 39. The first air blowing portion 2 that exhausts from the exhaust port 5 toward the outside of the main body casing 1.

The indoor air that has passed through the moisture absorbing portion 37 of the dehumidification rotor 39 shown in Fig. 8 flows into the outer casing 7 from the suction port 14 shown in Fig. 2, and is pressurized by the vanes 8, and is transmitted through the blowout port 16 and the exhaust gas. The port 5 is exhausted toward the outside of the body casing 1.

Further, as shown by an arrow B in FIG. 8 , the indoor air that has been sucked into the main body casing 1 from the intake port 4 by the first air blowing portion 2 is formed in the main body casing 1 through the moisture absorbing path 40. After the heat exchanger 42, the first air blowing portion 2 is exhausted from the exhaust port 5 toward the outside of the main body casing 1.

However, the indoor air of the arrow B and the air passing through the moisture absorption path 40 in the heat exchanger 42 are heat-exchanged through the heat transfer surface constituting the heat exchanger 42, and the heat exchanger 42 is not mixed with the air of the moisture absorption path 40.

Here, when the operation of the moisture absorption path 40 shown in Fig. 8 is described, the moisture absorption portion 37 of the air-based dehumidification rotor 39 of the moisture absorption path 40 heated by the heater 41 is rotated to the wet portion 38. The wet water is released, and the air in a high temperature and an excessive humidity state is sent to the heat exchanger 42 on the leeward side. As shown by the arrow B in the heat exchanger 42, the indoor air is blown by the first air blowing unit 2, so that the air in the high temperature and the excessive humidity is cooled and dew condensation, and the dew condensation water is accumulated in the receiving tray 44.

As shown by the arrow A, the moisture absorbing portion 37 adsorbs wet moisture every time the indoor air passes. Further, by the rotation of the dehumidification rotor 39, the adsorbed wet moisture is released into the moisture absorption path 40 by the wetted portion 38 to dehumidify the indoor air.

Further, as shown in Fig. 8, the ion generating unit 3 is located in the air passage between the intake port 4 of the main body casing 1 and the dehumidifying rotor 39, and faces the intake port 4. The ion generating unit 3 and the attracting unit 23 of the first air blowing unit 2 communicate with each other via the communication air passage 46.

Thereby, the first air blowing unit 2 dehumidifies the indoor air that has taken in air from the air intake port 4 into the main body casing 1 through the moisture absorbing portion 37 of the dehumidifying rotor 39, and passes through the suction port 14 and the air outlet 16 toward the exhaust port. 5 air supply. Further, the attraction portion 23 is introduced into the casing 7 by the air that has taken in air from the intake port 4 into the main body casing 1 through the ion generating portion 3 by the air blowing. The ion generating unit 3 generates ionized charged fine particle water from the inflowing indoor air. Here, as shown in Fig. 3, since the air path between the wrap surface 13 and the vane 8 gradually becomes wider toward the air outlet 16 from the position of the attracting portion 23, the air flowing through the air path It also flows gradually and gradually. In other words, the ions generated in the ion generating unit 3 and attracted to the inside of the casing 7 flow gradually between the attraction portion 23 and the air blown from the air outlet 16.

Therefore, ions generated from the ion generating portion 3 are blown from the exhaust port 5 everywhere. As a result, when the ions generated from the ion generating unit 3 are blown to the laundry and the laundry is dried, the laundry can be deodorized everywhere.

Fig. 10 is a perspective view showing the upper portion of the ion generating apparatus according to Embodiment 3 of the present invention. In the ion generating apparatus according to the third embodiment of the present invention, the freely rotatable wind direction louver 47 is provided in the exhaust port 5. The wind direction exhaust port vanes 47 have a substantially flat plate shape, and have shaft portions 48 that extend outward from the left and right end portions of the left and right sides of the main body casing 1. Further, the shaft portion 48 is rotatably attached to the bearing portion 49 of the exhaust port 5. Thereby, the wind direction of the ions from the exhaust port 5 can be changed in the elevation direction from the horizontal direction to the vertical direction.

However, when the wind direction louver 47 is rotated, the air blown in the outer casing 7 may be disturbed. Therefore, the attraction portion 23 is provided in the suction side surface 10 on the upstream side of the tongue portion 15 between the flap surface 13 and the blade 8 in the outer casing 7 as shown in Fig. 6. Since the exhaust port 5 and the attraction portion 23 are separated by a predetermined distance, the influence of the air blow disturbance in the outer casing 7 generated when the wind provided to the exhaust port 5 is swung to the louver 47 is lowered.

As a result, when the wind direction louver 47 is rotated and the wind direction changes to dry the laundry, the amount of fluctuation of the ions induced by the attraction portion 23 can be reduced, so that the laundry can be uniformly deodorized.

Further, as shown in FIG. 10, the main body casing 1 is provided with a second electric motor 50 that winds the wind toward the louver 47 to the louver rotating portion. The second electric motor 50 is coupled to the shaft portion 48 of the wind louver 47, and reciprocates the wind toward the louver 47 from the horizontal direction to the vertical direction.

As described above, when the wind direction louver 47 is reciprocated, the air supply is disturbed by the pressure change in the outer casing 7. However, the suction side surface 10 on the upstream side of the tongue piece portion 15 between the scroll surface 13 and the blade 8 is provided with the attraction portion 23 spaced apart from the exhaust port 5 by a predetermined distance. Therefore, the influence of the air blow disturbance in the outer casing 7 which is generated when the wind of the exhaust port 5 is reciprocated to the louver 47 is reduced. That is, the amount of fluctuation in the amount of ions induced by the attraction portion 23 is lowered.

As a result, when the wind direction louver 47 rotates back and forth, and the wind direction changes to dry the laundry, the amount of fluctuation of the amount of ions attracted by the attraction portion 23 can be reduced, so that the laundry can be uniformly deodorized.
