The ion generating device 25 which protrudes into the said air blower hole 21 is provided in 21 A of wall surfaces of a longitudinal end part.

3 is an exploded perspective view of the ion generating device 25, and FIG. 4 is an assembled view thereof. As shown in FIG. 3, the ion generating device 25 has a holder having an ion generating device main body 26 and a tip portion 27A inserted into the upper opening 26A of the ion generating device main body 26 ( 27, an ion generator 28 having an upward ion generating needle 28A fixed to a lower surface of the holder 27, and a fixing plate 29 for fixing the ion generator 28. It is. When assembling this, after integrating the holder 27, the ion generating body 28, and the fixed plate 29, the tip portion 27A of the holder 27 is inserted into the upper opening 26A, and finally, As shown in Fig. 4, this unit is fixed to the ion generating device main body 26 with a cover 30 and assembled.

As shown in FIG. 2, the ion generating device 25 has a length constituting the air blowing hole 21 by causing the tip portion 27A of the holder 27 to protrude into the air blowing hole 21. The ion generating device main body 26 can be fixed and attached to the wall surface 21A of the directional end. 3 and 4, the ion generating device 25 has a lead wire 31. When a predetermined voltage is applied through the lead wire 31, negative ions are generated from the tip of the ion generating needle 28A. Is released.

In the present embodiment, the ion generating device 25 is fixed to the rearward specific position in the air blowing hole 21 as described above.

That is, in the narrowed upstream position in the air blowing hole 21 surrounded by the scroll portion 17 and the tongue 19, as shown in Fig. 2, the longitudinal end portion constituting the air blowing hole 21 is shown. It is fixed to 21A of wall surfaces. Here, the rearward position in the air blowing hole 21 may be, for example, a narrowed upstream position in the air blowing hole 21 surrounded by the scroll portion 17 and the tongue 19. It is not limited to 21 A of wall surfaces of the longitudinal end part which comprise 21).

In the present embodiment, the ion generating needle 25 does not interfere with the direction control of the wind direction changing plate 23, and the ion generating needle even when the wind direction changing plates 23A to 23C are controlled in any direction. The negative ions emitted from the tip of 28A can be reliably loaded in the air flow from the air blowing hole 21. Therefore, even if the wind direction change plates 23A to 23C are controlled in any direction, the negative ions can be uniformly supplied into the chamber.

6 and 7 show another embodiment of the ion generating device 25.

In each figure, the same code | symbol is attached | subjected to the same component as FIG. 3 and FIG. 4, and the description is abbreviate | omitted. This ion generating device 25 includes an ion generator 28 having an ion generating needle 28A, and the ion generating needle 28A has an open space surrounded by an insulator as shown in FIG. 40) protrude into.

The insulator surrounding the open space 40 is fixed to the lower surface of the holder 27 and the holder 27 having the ion generating device main body 26, the tip portion 27A, and the ion generating body 28. It consists of a fixing plate for fixing.

The pair of tip portions 27A are provided so as to prevent the hand from touching the ion generating needles 28A.

As described above, the ion generating device 25 has a lead wire 31, and when a predetermined high voltage is applied through the lead wire 31, negative ions are released from the tip of the ion generating needle 28A.

However, as a result of the empirical test, when the ion generating device 25 was used for a long time, it was found that the negative charge is charged to the insulator surrounding the open space 40, in particular, the pair of tip portions 27A of the holder 27. . If this is left, the amount of negative ions emitted from the tip of the ion generating needle 28A decreases, but it is preferable to increase the amount of negative ions.

In order to increase the amount of this negative ion, a sheet metal ground member 41 is disposed in the vicinity of the ion generating needle 28A.

As shown in Fig. 6, the grounding member 41 has a grounding plate 41A, and the grounding plate 41A has an inner side of the pair of tip portions 27A, as shown in Fig. 7. It is disposed opposite the ion generating needle 28A to fill in the gaps. Between the ground member 41 and the holder 27, as shown in Fig. 6, a ground wire 45 is inserted, and they are coupled to the holder 46 and the nut 47. The ground wire 45 is connected to the air conditioner main body and grounded through the refrigerant pipe, the outdoor unit, and the like.

In the present embodiment, even when the ion generating device 25 is used for a long time, the negative electric charges charged to the pair of tip portions 27A run to the ground through the ground line 45, so that the pair of tip portions 27A ), The amount of charge to the N-) decreases, and the electric field strength near the open space 40 increases, thereby increasing the amount of negative ions emitted from the tip of the ion generating needle 28A.

As the ground plate 41A approaches the ion generating needle 28A, the electric field strength near the open space 40 increases, and the amount of negative ions emitted from the distal end of the ion generating needle 28A increases. On the other hand, if too close, corona discharge occurs between the ion generating needle 28A and the ground plate 41A. Therefore, it is installed as close as possible in the range where corona discharge does not occur.

In this embodiment, with reference to FIG. 6, the intermediate | middle insulator 27B of a protrusion form is formed in the holder 27. As shown in FIG. This intermediate insulator 27B protrudes between the ion generating needle 28A and the ground plate 41A so as to extend between the inner dimensions of the pair of tip portions 27A, as shown in FIG. The insulation creepage distance between 28A and the ground plate 41A is increased.

When the distance between the ion generating needle 28A and the ground plate 41A is short, when a high voltage is applied to the ion generating needle 28A, a current flows toward the ground plate 41A. If, for example, dust or the like is interposed therebetween, the current easily flows to the ground plate 41A via the dust or the like.

In this embodiment, by providing the intermediate insulator 27B, the flow of current to the ground plate 41A can be prevented.

The position of the intermediate insulator 27B is not limited between the ion generating needle 28A and the ground plate 41A. For example, it is apparent that the ground member may be made of an insulator (an electroconductive paint or an electroconductive plating formed on the back surface 27C of the pair of tip portions 27A) surrounding the open space.

FIG. 5 shows a display device which displays the flow direction of the ions contained in the air flow from the air blowing hole 21 and the flow rate thereof.

This display apparatus 31 is provided in the substantially center part (refer FIG. 1) of the longitudinal direction of the front surface of the air conditioner main body 1 (suction grill 11). This display device 31 is comprised by the display part (wind direction monitor) which displays the wind direction which consists of several LED string 31A-31C, and the display part (ion monitor) 31D which displays generation | occurrence | production of an ion. This LED 31D also serves as a filter signal, and when contamination of the filter is detected, the contamination is indicated, and thereafter, ion generation is not displayed until the contamination of the filter is removed.

Although several LED rows 31A-31C show the wind direction of the airflow from the air blowing hole 21, ion flows in this airflow. Therefore, each of the LED rows 31A to 31C indicates the flow direction of the ions.

For example, in Fig. 5, when the LED column 31A in the left column is lit, the air flow containing ions is blown from the air blowing hole 21 in the left direction, so that the LED column 31B in the center column is In the case of lighting, the air stream containing ions is blown to the center from the air blowing hole 21, and when the LED column 31C in the right column is lit, the air stream containing ions is the air blowing hole ( 21) in the right direction.

According to this, only in the lighting state of each LED column 31A-31C, it can confirm in which direction the ion flows.

When the wind speed from the air blowing hole 21 changes, the display form of each LED row 31A-31C is changed. If the amount of generated ions from the ion generating device 25 is approximately constant, the blowing amount of ions increases when the wind speed is increased.

For example, as a display form showing the flow direction of the air flow, when the LEDs 31A to 31C are turned on, the lighting is continuously turned on and off by changing the time from the upper LED to the lower LED. As the wind speed increases, the shape change such as decreasing the amount of change in time is adopted.

According to this, it is possible to confirm easily how much ion flows only by looking at the display form of each LED column 31A-31C.

As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to this.

In the present invention, even when the wind direction changing plate is controlled in any direction without disturbing the wind direction changing plate, it is possible to reliably carry negative ions to the airflow from the air blowing hole and to supply the inside of the chamber.

In the present invention, it is possible to easily determine how much ions are blown out in which rectangle of the chamber.
