  Next, installation of the ion generator 1 according to the first embodiment will be described. 11 is a plan view of the ceiling portion showing the installation state of the ion generator of FIG. 1, and FIG. 12 is a side sectional view of the ceiling portion showing the installation structure and operation of the ion generator of FIG.

  The ion generator 1 according to the present embodiment is installed on the ceiling 10 near the air outlet 91 of the ceiling-embedded air conditioner 9. The ceiling-embedded air conditioner 9 includes four outlets 91 for blowing air in four directions. The ion generator 1 is installed with respect to each air outlet 91 so that the air guide surface 34 is located on the side close to the air outlet 91 of the ceiling-embedded air conditioner 9. In addition, since the ceiling 10 is already provided with lighting or the like, the ion generator 1 cannot necessarily be installed for all the outlets 91, so it is attached only to some of the outlets 91. May be.

  The spacer 1B has a height and an inclination angle with respect to the ceiling 10 of the main body 1A of the ion generator 1 in accordance with the height (blowing position) of the air outlet 91 of the ceiling-embedded air conditioner 9 with respect to the ceiling 10 and the blowing direction. Is adjusted so that the blowing air is applied to the air guide surface 34 to increase the amount of air flowing into the inflow port 4 so that ions can be diffused efficiently.

  The ion generator 1 is attached and fixed near the ceiling 10 where the ceiling-embedded air conditioner 9 is installed, with the bottom 11 of the spacer 1B facing the wall of the ceiling 10. Therefore, the upper surface 31a of the main body 1A is inclined about 15 degrees with respect to the ceiling 10. A fixing bolt 81 is used for fixing. The fixing bolt 81 passes through the mounting holes 11a and 11b of the bottom 11 from the bottom 11 side of the spacer 1B and the hole opened in the ceiling 10, and is fixed with a nut 82 from the back side of the ceiling.

  The ceiling-embedded air conditioner 9 includes a suction port 95, a blower 94, a heat exchanger 93, and a blowout port 91. During operation of the ceiling-embedded air conditioner 9, indoor air is sucked from the suction port 95 by the blower 94, and conditioned air is blown from the blower outlet 91 through the heat exchanger 93. A wind direction changing plate 92 is installed at the air outlet 91.

  The conditioned air is blown out by the ceiling-embedded air conditioner 9 toward the inclined air guide surface 34 of the main body 1A of the ion generator 1. The conditioned air blown out flows along the air guide surface 34 as shown by the arrows. Further, in the portion where the inlet 4 of the air guide surface 34 is present, conditioned air flows from the inlet 4 into the ventilation path 7 inside the ion generator 1 as shown by the arrow in FIG. 6.

  Here, the ions generated by the ion generator 2 are released downward from the ion generators 21 and 22 of the ion generator 2 by the ion wind. The conditioned air flowing in from the inflow port 4 is added with ions generated by the ion generator 2 when flowing through the ventilation path 7, and the ionic air from the first air outlet 51 and the second air outlet 52 of the ion generator 1 is added. Released to the outside.

  Part of the conditioned air containing ions hits the wind shielding plate 6, is led to the first outlet 51, and flows out from the first outlet 51. The conditioned air containing the ions flowing out from the first outlet 51 merges with the conditioned air flowing along the air guide surface 34 and is blown out into the room. Further, the remainder of the conditioned air containing ions flows out from the second outlet 52. The conditioned air containing ions flowing out from the first outlet 51 and the conditioned air containing ions flowing out from the second outlet 52 can efficiently diffuse ions into the room.

  Thus, by providing the inflow port 4 on the inclined air guide surface 34, the conditioned air blown from the outlet 91 of the ceiling-embedded air conditioner 9 along the air guide surface 34 is inclined. It can be divided into air flowing along the wind surface 34 and air entering the ion generator 1 from the inlet 4 of the ion generator 1. And by providing the 1st outflow port 51 in the baffle surface 34 of the position downstream from the inflow port 4 in the flow direction of the conditioned air blown out from the outflow port 91 of the ceiling embedded type air conditioner 9, Part of the air that has flowed into the ion generator 1 and added with ions can flow out of the first outlet 51 and merge with the air flowing along the air guide surface 34 again.

  In the first embodiment, since the slit-like opening S in which the inlet 4 and the first outlet 51 are connected is formed, the flow rate, flow velocity, direction, and the like of the conditioned air flowing along the air guide surface 34. Correspondingly, the ratio of the portion of the opening S that becomes the inlet 4 and the portion of the opening S that becomes the first outlet 51 can be changed. When the partial ratio of the opening S serving as the inlet 4 increases, the amount of air entering the ion generator 1 increases, so that ions are added in the ion generator 1, and the first outlet 51 and the second From the outlet 52, air containing more ions can be discharged to the outside.

  In the first embodiment, by providing the wind shielding plate 6, the air containing the ions blown from the first outlet 51 is merged with the air flowing along the air guide surface 34 and diffused into the room. Thus, ions can be diffused efficiently in the room as compared with an ion generator in which the air guide plate 6 is not installed. The ratio of the amount of conditioned air flowing out from the first outlet 51 and the amount of conditioned air flowing out from the second outlet 52 can be changed by adjusting the length of the wind shield 6. . If the windshield 6 is lengthened, the proportion of the conditioned air flowing out from the first outlet 51 increases, and if the windshield 6 is shortened, the amount of conditioned air flowing out of the first outlet 51 is increased. The rate decreases.

  In addition, since the ion concentration detected by the ion detector 8 increases as the amount of air flowing in from the inlet 4 and hitting the windshield 6 increases, the ion display for displaying the detection result of the ion detector 8 Based on the display information, it is possible to confirm a state in which the air blown out from the outlet 91 of the ceiling-embedded air conditioner 9 flows into the inlet 4.

FIG. 23 is a sectional view showing an installation state of the ion generator shown in FIG.

  In Embodiment 2, in order to adjust the inclination angle and height of the main body 1A, instead of the spacer 1B, a ceiling side fixing member 22 fixed to the ceiling 10 and a main body side fixing member 23 fixed to the main body 1A Is different from the first embodiment.

  The ceiling side fixing member 22 is a bottomed rectangular tube having a substantially rectangular parallelepiped shape with an open lower surface. Similar to the spacer 1B of the first embodiment, one round hole mounting hole (not shown) and two long hole mounting holes 22c are provided at the bottom of the ceiling side fixing member 22. The ceiling side fixing member 22 is attached to the ceiling 10 using these attachment holes 22c. Two rows of holes 22a and 22b spaced apart in the circumferential direction are provided on both side surfaces in the longitudinal direction of the ceiling-side fixing member 22, and the holes 22a in one row are round holes and the holes 22b in the other row are circumferential. Long holes in the direction. Three holes 22a and 22b in each row are provided at equal intervals in the axial direction of the cylinder, and the circumferential positions of the round holes 22a and the long holes 22b are the same.

  The main body side fixing member 23 is a rectangular tube having a substantially rectangular parallelepiped shape. Since the main body side fixing member 23 is located in the ceiling side fixing member 22, the size of the main body side fixing member 23 is slightly smaller than the ceiling side fixing member 22. Protrusions 23a projecting outward along the side surfaces are provided at the edges of both side surfaces in the longitudinal direction of the main body side fixing member 23. The protrusion 23a has a mounting hole 23a1 through which a mounting screw is passed. When the main body side fixing member 23 is attached to the main body 1A, the projections 23a are fitted into the recesses 31b of the base portion 31, and screws through the mounting holes 23a1 are screwed into the screw holes 31c so that the main body side fixing member 23 is attached to the main body 1A. Fixed to.

  At both ends in the longitudinal direction of the main body side fixing member 23, two movable pins 24 spaced apart in the circumferential direction are provided on the end side opposite to the side on which the protrusion 23a is provided. The distance between the two movable pins 24 is substantially equal to the center-to-center distance in the circumferential direction of the holes 22a and 22b of the ceiling side fixing member 22. An L-shaped pin holding portion 25 that sandwiches the movable pin 24 between the inside of the side wall 23 b of the main body side fixing member 23 is fixed to the side wall 23 b of the main body side fixing member 23. The movable pin 24 has a cylindrical portion 24a that fits into the holes 22a and 22b of the ceiling-side fixing member 22, a flange portion 24b, and a guide portion 24c that extends from the flange portion 24b in the opposite direction to the cylindrical portion 24a. ing. Further, a spring 26 that is inserted through the guide portion 24c and pressurizes the flange portion 24b is disposed between the flange portion 24b and the pin holding portion 25.

  When the movable pin 24 is pushed inward, the flange portion 24 b of the movable pin 24 compresses the spring 26, and the movable pin 24 can be pulled out from the holes 22 a and 22 b of the ceiling side fixing member 22. By removing one of the movable pins 24 from the holes 22a and 22b of the ceiling side fixing member 22, the main body side fixing member 23 can be rotated around the movable pin 24 not extracted from the holes 22a and 22b. Each of the movable pins 24 extracted from the holes 22a and 22b can be moved to the positions of the other holes 22a and 22b and fitted. Thus, the holes 22a and 22b into which the movable pins 24 are fitted can be selected, and the relative angle and relative position of the main body side fixing member 23 to the ceiling side fixing member 22 can be changed. As a result, the distance from the ceiling 10 of the main body 1A and the inclination angle with respect to the ceiling 10 can be changed. In the configuration shown in FIG. 17, the distance from the ceiling 10 is adjusted in three steps, and the inclination angle with respect to the ceiling 10 is adjusted in two steps.

  24 to 27 are side views illustrating the installation form of the ion generator 1 shown in FIG. FIG. 24 shows a case where the distance between the main body 1 </ b> A and the ceiling 10 is closest and is not inclined with respect to the ceiling 10.

FIG. 26 shows a case where the distance to the ceiling 10 is in the middle of three stages and is inclined by one stage with respect to the ceiling 10. FIG. 27 shows the case where the distance from the ceiling 10 is the longest and is not inclined with respect to the ceiling 10. Here, when the main body-side fixing member 23 is inclined with respect to the ceiling-side fixing member 22, the distance in the circumferential direction between the movable pins 24 that fit into the holes 22a and 22b in each row changes. The hole 22b absorbs a change in distance. 25 and 26, the main body side fixing member 23 is set so that the distance from the ceiling 10 of the movable pin 24 fitted into the long hole 22b is longer than the distance from the ceiling 10 of the movable pin 24 fitted into the hole 22a. However, the distance from the ceiling 10 of the movable pin 24 that fits into the long hole 22b is smaller than the distance from the ceiling 10 of the movable pin 24 that fits into the hole 22a. It can also be tilted so that it is close.

  In said Embodiment 1-2, although the ion generator 1 which concerns on this invention was installed in the ceiling 10 near the blower outlet 91 of the ceiling-embedded air conditioner 9, it is not restricted to a ceiling-embedded air conditioner.
