  During this time, negative ions and positive ions are generated from the negative ion generator and the positive ion generator of the ion generator 50, respectively. The ion generator 50 is separated from the first path 46 and is located on the second path 47 side. For this reason, more ions are included in the air flow passing through the second path 47 than in the first air flow passing through the first path 46.

  Moreover, since the 1st path | route 46 exists in the outer peripheral side rather than the 2nd path | route 47, the wind speed of the 1st airflow located in an outer peripheral side becomes quicker than the wind speed of the 2nd airflow located in an inner peripheral side. For this reason, the 1st airflow blown from the 1st blower outlet 26 functions as an air curtain, and suppresses the spreading | diffusion of ion upwards.

  Here, an external louver 60 is provided in the central region R2 (see FIG. 2). The external louver 60 guides the air flow blown from the upper air outlet 28, that is, the air flow passing through the upper side of the external louver 60 out of the first air flow and the second air flow upward. . Since the air flow having a high wind speed is guided upward, it is possible to prevent the air flow having a high wind speed from hitting the user when the user is sitting in front of the central region R2 for a certain period of time.

  Note that an air flow having a high wind speed guided upward by the external louver 60 having a predetermined inclination or curvature also functions as an air curtain. For this reason, it is possible to moderately suppress the diffusion of ions contained in the air flow blown from the lower outlet 29 of the central region R2. Thereby, the ion which has a disinfection effect can be carried to a user's circumference | surroundings, preventing that an air flow with a high wind speed hits a user.

  Subsequently, while comparing the air flow blown from the ion generator in Comparative Example 1 and Comparative Example 2 with the air flow blown from the ion generator 1 according to the present embodiment, the ions according to the first embodiment are compared. The effect of the generator 1 will be described.

  FIG. 16 is a diagram showing an air flow blown from the ion generator in Comparative Example 1. FIG. 17 is a diagram showing a wind speed distribution at a predetermined position of the air flow blown from the ion generator in Comparative Example 1. FIG. 18 is a diagram showing the concentration distribution of ions contained in the air flow blown from the ion generator in Comparative Example 1. With reference to FIGS. 16 to 18, the air flow delivered from the ion generator in Comparative Example 1 will be described.

  In addition, the airflow of FIGS. 16-18 is blown in the state which the housing | casing of an ion generator is located in the lowest position. 16 and 18 show the air flow in a plane parallel to the center line C1 (see FIG. 2) and the front-rear direction (Y-axis direction) of the ion generator, and the ion concentration contained therein. .

  Further, the position where the user is sitting is a position 1.0 m away from the central region of the ion generator 1, and the position of the head when the user is sitting is 1.2 m from the floor. This head position is defined as a position P1.

  The ion generator in the comparative example 1 is different in that the external louver 60 is not provided when compared with the ion generator 1 according to the first embodiment. Other configurations are almost the same.

  As shown in FIG. 16, in the ion generator in the comparative example 1, the external louver 60 is not provided, and an air flow with a high wind speed cannot be guided upward. In this case, the elevation angle θ1 of the center line L1 of the air flow is approximately 29 degrees. Here, the center line of the air flow is a line connecting portions where the wind speed is highest when the air flow is divided into a plurality of parts in the front direction.

  In this case, the airflow blown out from the blowout port in the central region R2 (see FIG. 2) of the ion generator is blown out so that the upper side passes through the position P1. For this reason, the airflow which blows off from the said blower outlet hits a user's head vicinity directly.

  FIG. 17 shows a wind speed distribution in a predetermined region in a plane orthogonal to the front direction and parallel to the left-right direction at a position 1.0 m forward from the center of the ion generator. The predetermined region is, for example, a rectangular shape having a width of 80 cm in the left-right direction and a height of 140 cm in the up-down direction around the portion corresponding to the center line of the ion generator in the plane. It is an area. The upper end of the region is located 140 cm from the floor surface.

  As shown in FIG. 17, the wind speed is in the range of greater than 1.0 m / s and less than or equal to 1.5 m / s, and the fastest air flow F1 is located within the range of 70 cm to 115 cm from the floor surface. The air flow F2 in which the wind speed is greater than 0.5 m / s and 1.0 m / s or less and then increases is present so as to surround the fastest air flow F2 within the range of 60 cm to 115 cm from the floor surface. . An air flow F3 having a wind speed of 0.5 m / s or less and a slow wind speed exists so as to surround the air flow F2.

  As described above, in Comparative Example 1, since the airflow with the fastest wind velocity hits the vicinity of the user's head, the user may feel the airflow uncomfortable.

  On the other hand, as shown in FIG. 18, the ion generator in the comparative example 1 can send the air containing a considerable amount of ions toward the upper part of the room. The ions sent upward in the room descend toward the floor with time. For this reason, ions can be sufficiently supplied into the room.

  In addition, ion concentration becomes small in order as it leaves | separates from a blower outlet along a blowing direction (it goes to area | region A5 from area | region A1). Although the region A1 having the highest ion concentration is located slightly below the position P1, it is possible to send a sufficient amount of ions toward the user in order to exert effects such as sterilization.

  FIG. 19 is a diagram showing an air flow blown from the ion generator in Comparative Example 2. FIG. 20 is a diagram showing a wind speed distribution at a predetermined position of the air flow blown from the ion generator in Comparative Example 2. FIG. 21 is a diagram showing the concentration distribution of ions contained in the air flow blown from the ion generator in Comparative Example 2. With reference to FIG. 19 to FIG. 21, the air flow delivered from the ion generator in Comparative Example 2 will be described.

  19 is a diagram corresponding to FIG. 16, FIG. 20 is a diagram corresponding to FIG. 17, and FIG. 21 is a diagram corresponding to FIG. The airflow shown in FIGS. 19 to 21 is blown out in a state where the casing of the ion generator according to Comparative Example 1 is moved upward by 30 cm from the lowest position.

  As shown in FIG. 19, the elevation angle θ <b> 2 of the center line L <b> 2 of the air flow blown from the ion generator in Comparative Example 2 is approximately 27 degrees, which is substantially the same as the elevation angle θ <b> 1 of Comparative Example 1. For this reason, as shown in FIGS. 19 to 21, the state of the air flow in the comparative example 2 is substantially equivalent to the state in which the air flow in the comparative example 1 is moved upward by 30 cm.

  Specifically, as shown in FIG. 19, the center line L2 passes slightly above the position P1, and as shown in FIG. 20, the center of the air flow F1 with the fastest wind speed is located slightly above the position P1. . For this reason, the air flow F1 with the fastest wind speed directly hits the user's head, and the user may feel the air flow uncomfortable.

  On the other hand, as shown in FIG. 21, the ion generator in the comparative example 2 can also send air containing a considerable amount of ions toward the upper part of the room. Ion concentration is measured at each of a plurality of lattice points that are located in front of an ion generator at a predetermined distance and divided into a lattice shape in a plane parallel to the center line of the ion generator and the horizontal direction. In this case, the average value of the ion concentration is only about 13% lower than that of Comparative Example 1 in both the positive ion concentration and the negative ion concentration.

  For this reason, in Comparative Example 2, it can be said that ions can be sufficiently supplied into the room as in Comparative Example 1. Further, the region A1 where the ion concentration is highest spreads in the blowing direction so as to include the position P1. For this reason, it is also possible to send a sufficient amount of ions to the user in order to exert effects such as sterilization.

  FIG. 22 is a diagram showing an air flow blown from the ion generator according to the present embodiment. FIG. 23 is a diagram showing a wind speed distribution at a predetermined position of the air flow blown from the ion generator according to the present embodiment. FIG. 24 is a diagram showing a concentration distribution of ions contained in an air flow blown from the ion generator according to the present embodiment. With reference to FIG. 22 to FIG. 24, the air flow blown out from the ion generator 1 according to the present embodiment will be described.

  22 is a diagram corresponding to FIG. 16, FIG. 23 is a diagram corresponding to FIG. 17, and FIG. 24 is a diagram corresponding to FIG. The air flow shown in FIGS. 22 to 24 is blown out in a state where the casing 2 of the ion generator 1 is moved upward by 30 cm from the state where the casing 2 is located at the lowest position.

  As shown in FIG. 22, by providing the external louver 60, the air flow blown out from the outlet in the central region R2 is directed upward. In this case, the elevation angle θ3 of the center line L3 of the air flow is larger than the elevation angle in Comparative Examples 1 and 2, and is approximately 38 degrees.

  The airflow blown out from the blowout port located in the central region R2 of the ion generator 1 passes above the position P1 as a whole. For this reason, the airflow blown from the blower outlet located in center area | region R2 does not hit a user substantially.

  As shown in FIG. 23, the air flow F2 with the next highest wind speed is located above the position 120 cm from the floor surface and exists so as to surround the fastest air flow F1. Moreover, the air flow F3 with a slow wind speed exists so that the air flow F2 may be surrounded. Although not shown in FIG. 23, the lower end of the position corresponding to the center line C1 in the air flow F1 with the highest wind speed is slightly lower than 150 cm at the lower end of the air flow F1 in the portion where the value of the abscissa is 0. Located at a high position.

  In the present embodiment, the air flow F1 with the fastest wind speed does not hit the user, but the air flow F3 with the slow wind speed hits the user. The air flow F3 is a wind that does not cause discomfort to the user. For this reason, in this Embodiment, a user's discomfort can be reduced significantly.

  As shown in FIG. 24, the ion generating apparatus according to the present embodiment can also send air containing a considerable amount of ions upward in the room. The ions sent upward in the room descend toward the floor with time.

  By providing the external louver 60, the ion diffusion state is slightly different from that of the first comparative example. Ion concentration is measured at each of a plurality of lattice points that are located in front of an ion generator at a predetermined distance and divided into a lattice shape in a plane parallel to the center line of the ion generator and the horizontal direction. In this case, the average value of the ion concentration is only about 10% lower than that of Comparative Example 1 in both the positive ion concentration and the negative ion concentration. For this reason, it can be said that the ion generator 1 according to Embodiment 1 can sufficiently supply ions into the room.

  In addition, the region A1 where the ion concentration is highest spreads in the blowing direction so as to include the position P1. For this reason, it is also possible to send a sufficient amount of ions to the user in order to exert effects such as sterilization.

  In addition, when the position of the housing | casing 2 is made into the lowest position, it will be located in the position from which the position of the air flow F1, the air flow F2, and the air flow F3 became about 30 cm low from the state of FIG. In this case, the lower end of the air flow F1 in the portion where the value of the abscissa is 0 is located slightly above 120 cm. The lower end of the air flow F1 is inclined downward while spreading in the left-right direction from the portion where the value of the abscissa is zero. For this reason, the air flow F1 with the fastest wind speed does not hit the user's head.

  In this case, the air flow F2 hits the user's head. However, since the air flow F2 has a lower wind speed than the air flow F1, discomfort given to the user can be reduced. . In this case as well, since an air flow containing a considerable amount of ions can be blown upward in the room, ions can be sufficiently supplied into the room.

  As described above, the ion generator 1 according to the present embodiment has a sense of discomfort and discomfort given to the user while sending sufficient ions for sterilization and the like to the user as compared with Comparative Examples 1 and 2. Can be reduced.

  FIG. 25 is a diagram showing the relationship between the case and the foot when the case of the ion generator according to the present embodiment is raised and lowered. Referring to FIG. 25, the relationship between the foot and the case when the case 2 of the ion generator 1 is raised and lowered is shown.

  As shown in FIG. 25, since the ion generator 1 has a considerable weight, when the casing 2 of the ion generator 1 is lifted and lowered by one person, the base part 5 may be stepped on with a foot so that the tension is effective. is there.

  In order to move the housing 2 in the vertical direction, first, the fastening of the fixing member 6 is loosened and the fixing member 6 is extracted from the insertion hole of the support column 4. Subsequently, guide protrusions (not shown) provided in the left side surface portion 2 a and the right side surface portion 2 b are slid along the groove portion 4 a of the support column portion 4.

  Next, the through hole 7 provided in the left side surface portion 2a and the right side surface portion 2b is aligned with the insertion hole of the groove portion 4a provided at a predetermined position. Subsequently, the fixing member 6 is inserted into the insertion hole and tightened to fix the housing 2 at a predetermined height position.

  The guide protrusion is provided below the through hole 7. For this reason, when the guide projection reaches the lower end of the groove 4a, the housing 2 is positioned at the lowest position. By restricting the movement range of the housing 2 in this way, the ion generator 1 according to the present embodiment is capable of the bottom surface portion 2c of the housing 2 even when the housing 2 is located at the lowest position. And the foot are configured not to contact each other.

  For this reason, it can prevent that a leg is pinched by the bottom face part 2c of the housing | casing 2, and the upper surface of the base part 5, and can ensure the safety | security of a raising / lowering operation | work.

  In the present embodiment, the case where the restricting means for restricting the vertical movement range of the casing 2 is configured by the guide protrusion and the groove has been described as an example. However, the present invention is not limited to this, and the stopper The restricting means may be configured by a member such as.

  The suction grill 11 </ b> A is installed in the suction port 10 and has a plurality of openings 12 and 13. In the housing 2, a part of the blower cover 31 is arranged so as to face the rear side of the suction port 10 in the left-right direction.

  The portion of the suction grill 11 </ b> A that does not face the blower cover 31 is configured by a plurality of openings 12 that are formed so as to prevent the fingertip from entering. That is, the size of the opening 12 is smaller than the fingertip.

  On the other hand, a portion of the suction grill 11A facing the blower cover 31 is configured to include an opening 13 formed so that a fingertip can enter. For example, the opening 13 is preferably provided on each of both end sides in the left-right direction. Of the portion of the suction grill 11 </ b> A that faces the blower cover 31, the portion other than the opening 13 is configured by the opening 12 that is formed to prevent the fingertip from entering.

  When removing the suction grille 11A, first, the fastening member for fastening the suction grille 11A to the housing 2 is removed. Next, a fingertip is inserted into the opening 13 and a part of the suction grill 11A is hooked on the fingertip. Subsequently, the suction grill 11A can be easily removed from the suction port 10 by hooking the suction grill 11A on the fingertip and pulling it. Thus, since it takes no effort to remove the suction grill 11A, the components in the housing 2 can be easily replaced or cleaned. As a result, workability such as component replacement and cleaning can be greatly improved.

  Moreover, since the blower cover 31 is provided in the part facing the opening part 13 in the housing 2, it is possible to prevent the fingertip from being caught in the blades of the blower 30. Thereby, safety can be ensured.

  Thus, the ion generator 1A according to the present embodiment is installed at the suction port while ensuring safety in addition to obtaining substantially the same effect as the ion generator 1 according to the first embodiment. Therefore, it is possible to provide an ion generator that can easily remove the suction grill and can improve workability such as cleaning.

Note that the stepping-in preventing means 90 itself may be a protrusion. The step-in prevention means 90 may be configured integrally with the base portion 5 by injection molding or the like, or may be configured separately.

  In this case, when the user raises or lowers the casing 2 of the ion generator 1B alone, when the base unit 5 is stepped on, the sole contacts the protrusion 91 (protruded portion). For this reason, the user feels uncomfortable on the sole of the foot, avoids stepping into the base portion 5, and moves the foot from the base portion 5 side to the floor surface. Thereby, even if it is a case where the housing | casing 2 is lowered | hung to the lowest position, it can prevent that a leg | foot is pinched by the housing | casing 2 and the base part 5. FIG. As a result, the ion generator 1B according to the present embodiment can ensure the safety of the lifting operation.
