As shown in FIGS. 1-9, the main body 1 is embedded in the ceiling 100 and the ion generator which generates ion from the ceiling 100 is concerned, As shown in FIG. 1, the main body 1 has a cylindrical shape. A flange 5 is provided below, a grill 5 having a suction port 3 and a blow-out port 4 is provided below the flange 2, and a top surface 6 of the main body 1 is provided with a turbo fan 7 serving as a centrifugal blower. An electric motor 8 that rotates the turbo fan 7 is provided. A top plate 9 that holds the electric motor 8 is provided on the top surface 6, and a turbo fan 7 that connects the electric motor 8 is incorporated below the top plate 9. Yes.

  The electric motor 8 may be either direct current (DC) or alternating current (AC).

  In addition, the air passage structure sucks indoor air from the entire circumference of the suction port 3, is sucked into the turbo fan 7 through the cylindrical path 11 a through the orifice 10, and is blown out to the entire circumference of the turbo fan 7. It passes through a cylindrical path 11b on the outside and is discharged from the entire circumference of the outlet 4 of the grill 5 into the room.

  Further, as shown in FIG. 2, an electric atomizer 12a for generating ions with the electric motor 8 and a control circuit 13 for controlling the electrostatic atomizer 12b (see FIG. 1) are provided above the top plate 9. And the control circuit case 14 is covered with a control circuit case cover 15.

  Further, in order to fix the main body 1 to the ceiling 100, as shown in FIG. 3, a mounting bracket 16 is provided on the side surface of the main body 1, and the mounting bracket 16 includes two components, a plate-shaped fixing bracket 17 and a root bracket 18. The root metal fitting 18 can be rotated so that the surface of the ceiling 100 and the base metal fitting 18 are parallel to each other around the contact surface in contact with the fixed metal fitting 17. A fixing nut 22 is provided at the front end of the metal threading screw 21 that passes through the hole 20 in the advancing direction.

  By rotating the bracket-dedicated screw 21, the fixing nut 22 whose movement in the rotational direction is restricted is moved up and down by the U-shaped wall 23 having a concave shape on the ceiling 100 side provided on the side surface of the main body 1. The metal fitting 16 is moved downward, and the main body 1 is fixed to the ceiling 100 by sandwiching the ceiling 100 between the flange 2 and the attachment metal fitting 16 (see FIG. 2).

  Here, in this product, the mounting bracket 16 has two structures on the left and right sides, that is, the side surfaces of the main body 1, but the number is not limited to this.

  Moreover, as shown in FIG. 4, it is also possible to attach to the ceiling 100 by inserting a screw into an attachment hole 24 provided in the flange 2 and tightening it.

  The mounting hole 24 has a structure in which the mounting hole 24 is closed in order to prevent air leakage during normal use. However, since the mounting hole 24 is closed with a thin wall, when the screw is inserted into the mounting hole 24, the mounting hole 24 is easily inserted. Can do.

  Further, as shown in FIG. 5, the ions generated by the electrostatic atomizing means 12a and the electrostatic atomizing means 12b pass through the guide 25a and the guide 25b provided inside the main body 1, and the ion discharge port 26a and the ion discharge. This structure is discharged from the outlet 26b, and is mixed with the air blown out by the turbofan 7 and discharged into the room.

  Note that the air discharged from the turbofan 7 causes the ion discharge port 26a and the ion discharge port 26b to have a negative pressure, and the ions generated by the electrostatic atomizing unit 12a and the electrostatic atomizing unit 12b pass through the guide 25a and the guide 25b. Since the ions are pulled to the ion discharge port 26a and the ion discharge port 26b, there is no possibility that the generated ions will flow backward, and dust and foreign matter pass through the guide 25a and the guide 25b and the electrostatic atomizing means 12a and the electrostatic discharge The structure has no risk of entering the atomizing means 12b.

  Further, as shown in FIG. 6, the orifice 10 is attached by rotating in the arrow direction 27 along the inside of the flange 2, positioned by a rotation restricting rib 28 provided in the inside of the flange 2, and the orifice fixing screw 29. It is a structure fixed to a regular position by.

  In addition, the orifice 10 has a switch control circuit 30 (see FIG. 1), is provided with an operation changeover switch 31 that can switch between operation and stop of the main body 1 and is lit when the main body 1 operates. A lamp 32 (see FIG. 1) is provided, and a dimming switch 33 for adjusting the light intensity of the operation lamp 32 is provided, which is covered with a protective cover 34 and is brought into a normal position by an orifice fixing screw 29. The structure is fixed.

  Further, an intrusion prevention rib 35 is provided above the protective cover 34 to prevent the finger from accidentally coming into contact with the turbo fan 7 when, for example, the operation switch 31 or the dimmer switch 33 is operated with the finger. In this structure, dust and foreign matter that have entered through the suction port 3 are prevented from entering the switch control circuit 30 (see FIG. 1) through the gap between the operation switch 31 or the dimming switch 33.

  Further, as shown in FIG. 1, a light tube 36 through which the light of the driving operation lamp 32 passes is provided below the protective cover 34, and the light of the driving operation lamp 32 is transmitted to the grill 5 so that the light is transmitted from the surface of the grill 5. It is emerging.

  In addition, since the surface of the grill 5 through which the light of the driving operation lamp 32 passes is provided with a circular recess 37 as an example, the surface of the grill 5 on the driving operation lamp 32 becomes thin. The light transmittance of the operation lamp 32 is increased, and the lamp is more clearly highlighted. For a user who feels bright, the light intensity can be adjusted using the dimming switch 33.

  In the above configuration, as shown in FIG. 7, the control circuit case 14 and the control circuit case cover 15 are each rectangular and have a size smaller than the diameter value of the cylindrical main body 1, and in the longitudinal direction. Since the main body 1 is arranged close to one side from the center, the control circuit case 14 and the control circuit case cover 15 can be easily inserted by inserting the main body 1 obliquely into the round hole of the ceiling 100. can do.

  As shown in FIG. 8, the control circuit case 14 is provided with a quick connection terminal 39 for connecting the control circuit 13 and the power supply line 38, and the quick connection terminal 39 is provided with a button 40 for attaching / detaching the power supply line 38.

  Alternatively, the quick connection terminal 39 may be inclined obliquely downward from the electric motor 8 side toward the outer periphery.

  As a result, when water leakage and dew condensation water that has occurred on the back of the ceiling 100 has been transmitted through the power supply line 38, the water leakage and dew condensation water have been transmitted through the power supply line 38 that is inclined downward in the same manner as the quick connection terminal 39. Since it flows along the power supply line 38 away from the quick connection terminal 39 in an oblique direction, water does not enter the insertion hole 41 and a tracking phenomenon can be prevented and safety can be improved.

  Alternatively, the eaves 42 may be provided to cover the control circuit case cover 15 above the insertion hole 41 of the quick connection terminal 39.

  As a result, when water leakage / condensation water generated on the back of the ceiling 100 falls on the control circuit case cover 15, the water leakage / condensation water flows forward from above the eaves 42, so that it does not flow into the insertion hole 41, and quick connection When the terminal 39 is pushed down by the eaves 42, the lowermost part of the power line 38 becomes lower than the insertion hole 41, and when water leakage or dew condensation water travels along the power line 38, the water moves diagonally downward from the quick connection terminal 39. Thus, the water flows along the power supply line 38, so that water does not enter the insertion hole 41, and the tracking phenomenon can be prevented and the safety can be improved.

Alternatively, the quick connection terminal 39 may be disposed outside the motor 8 of the control circuit case 14.

  As a result, since a space is created below the control circuit case 14, the button 40 can be pushed from the space below with, for example, an index finger, and workability when inserting or removing the power supply line 38 to or from the quick connection terminal 39 is improved. can do.

  Further, a configuration in which a rib 43 is provided above the quick connection terminal 39 of the control circuit case cover 15 may be adopted.

  As a result, since the quick connection terminal 39 comes into contact with the rib 43 and is caught, even when the power line 38 is inserted into the quick connection terminal 39 and pulled, the quick connection terminal 39 can be removed from the control circuit case 14. Can be prevented.

  Furthermore, as shown in FIG. 9, the control circuit case 14 and the control circuit case cover 15 are installed so that the control circuit case cover 15 and the work table 44 (such as a desk may be a flat surface) are in contact with each other. Since the control circuit case cover 15 and the work table 44 are both flat, the power line 38 can be inserted or removed in a more stable state, thereby improving workability. be able to.

  Further, as shown in FIGS. 10 and 11, a circuit cover 46 that covers the power line connecting portion 45 of the quick connection terminal 39 is provided so as to cover the control circuit case 14 and the control circuit case cover 15.

  With this configuration, the control circuit case 14 and the control circuit case cover 15 are inserted into the power supply line 38 (see FIG. 8) from the right vertical direction. When used, the heat insulating material (not shown) can be prevented from entering the power line connecting portion 45 by the circuit cover 46, and the safety of the power line connecting portion 45 can be maintained.

  The control circuit case cover 15 is provided with a groove 47 and a screw hole 48 so as to hold the circuit cover 46.

  With this configuration, the circuit cover 46 is coupled to the groove 47 and slid, and a screw (not shown) is inserted into the screw hole 48 from above to couple the circuit cover 46 and the control circuit case cover 15 together. Therefore, the circuit cover 46 is coupled to the control circuit case cover 15 as necessary (when the blowing method is used), so that the safety of the power line connecting portion 45 can be maintained in any case (method). .

  The ion generating apparatus according to the present invention is attached to the ceiling and enables ion supply in a wide range, and is therefore useful for supplying the living space with the effects and effects that can be brought about by ions. It is also useful in non-residential spaces such as bathrooms, toilets, or warehouses.
