Description

  The present invention relates to a blower-type ion generator in which a blower is installed in a housing having a blower outlet, a discharge electrode is disposed between the blower outlet and the blower, and ions generated by the discharge are blown out from the blower outlet.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-234972) discloses an ion generator of this type having a cleaning mechanism that automatically cleans a discharge needle as a discharge electrode with a brush. That is, the cleaning mechanism attaches a brush to a movable member that is moved by wind force from a blower, and swings the brush by wind force to clean (brush) the tip of the discharge needle, or to a movable member that is operated by an electric motor. A brush is attached, and the tip of the discharge needle is cleaned by turning the brush with an electric motor.

However, according to this, although the discharge needle can be automatically cleaned with a brush, there are the following problems.
(1) Since the main body is provided with a cleaning mechanism for operating the brush by wind power from a blower or an electric motor, the apparatus becomes complicated and large, and the cleaning mechanism requires a brush corresponding to each discharge needle. Therefore, it becomes expensive.
(2) Since a cleaning mechanism having such a brush is present in front of the discharge needle, this disturbs the wind and causes ion unevenness.
(3) Dust dropped from the discharge needle by brushing remains in the main body.
(4) Since the cleaning mechanism itself is contaminated with dust or the like, it needs to be cleaned.
JP 2004-234972 A

  The main object of the present invention is to facilitate manual cleaning rather than enabling the discharge electrode to be automatically cleaned, and the mechanism for performing manual cleaning is simple, making the apparatus complicated and large. An object of the present invention is to provide an air blowing type ion generator that does not cause turbulence or wind disturbance.

  The blower type ion generator according to the present invention supports a discharge electrode on a rotating frame supported by a housing at an outlet and forms an electrode unit. The rotating frame is rotated to place the discharge electrode in the housing. It is characterized in that it can be switched and switched between a storage position to be stored and a take-out position to go out of the air outlet.

  In the preferable form, a blower outlet is horizontally long or vertically long, a discharge electrode is acicular, and the plurality is hold | maintained along the blower outlet to the rod-shaped electrode holder constructed by the rotation frame.

  A rod-shaped ground electrode is installed on the rotating frame in parallel with the electrode holder so as to maintain a certain distance from the needle-shaped discharge electrode.

Two fans whose fan rotation directions are opposite to each other are installed in the housing at an interval in the length direction of the air outlet.
On both sides of the installation positions of the two blowers, wind direction plates that extend to both ends of the air outlet are installed.

A sensor for detecting whether the electrode unit is in the storage position or the extraction position is provided.
The sensor may be a microswitch that is turned on / off by the rotation of the rotation frame.

  According to the first and second aspects of the present invention, since the discharge electrode can be taken out to the outside of the air outlet by rotating the rotating frame of the electrode unit, the discharge electrode can be easily cleaned outside the housing. In addition, the work can be easily performed even with fine cleaning, and the inside of the housing is not soiled by the cleaning. Moreover, since it can be taken out with a simple mechanism, it can be provided at low cost.

  When the rod-shaped ground electrode is installed on the rotating frame in parallel with the rod-shaped electrode holder as in the invention according to claim 3, the ground electrode can be cleaned simultaneously under the same conditions, and the discharge electrode is needle-shaped, that is, the discharge When the needle is used, the ground electrode can prevent the finger from touching the discharge needle.

  As in the invention according to claim 4, when two fans whose fan rotation directions are opposite to each other are installed in the housing at intervals in the length direction of the air outlet, the air flow rate is the length direction of the air outlet. Therefore, when the charge is eliminated or charged with ions, uniform charge removal, charge or sterilization can be performed. If the wind direction board extended to the both ends of a blower outlet is installed in the both sides of the installation position of two air blowers like the invention which concerns on Claim 5, such an effect will become still better.

  As in the inventions according to claims 6 and 7, if the sensor detects whether the electrode unit is in the storage position or the extraction position, the power to the electrode unit is turned off when cleaning the electrode unit in the extraction position. You can work safely.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a front view of the blow type ion generator of the present embodiment, FIG. 2 is a rear view, FIG. 3 is an internal plan view, FIG. 4 is an internal perspective view, and FIG.

  This blower type ion generator has a horizontally long air outlet 2 formed in a front plate 1a of a horizontally long box-shaped housing 1 as a main body, and ions generated from an electrode unit 3 in the housing 1 It blows out by the ventilation from the two air blowers 4 and 5 installed in the.

  The electrode unit 3 is a horizontally long length that can be accommodated in the air outlet 2, so that the electrode unit 3 can be switched between a storage position accommodated in the housing 1 and a take-out position that exits outward from the air outlet 2. The structure is as follows.

  The electrode unit 3 includes ribs 6 and 7 at both left and right ends, three intermediate ribs 8, 9, and 10, and the intermediate ribs 8, 9, 10 passing through both ends at the upper ends of the ribs 6, 7 at both left and right ends A rotating frame 12 is constituted by a stay 11 which is a metal round bar fixed to the part. Then, the rotating frames 12 are housed by bearing the shafts 13 and 14 provided on both sides of the ribs 6 and 7 at both ends of the ribs 6 and 7 on the bearing members 15 and 16 on both ends of the air outlet 2. 1 is freely rotatable. FIG. 6 shows the left bearing portion, and FIGS. 7 and 8 show the right bearing portion. The ribs 6, 7, 8, 9, and 10 are all made of the same resin (thus electrically insulating) and have a substantially semicircular cam shape without corners.

  Also, one electrode holder 17 that is also a metal round bar passes through the intermediate ribs 8, 9, and 10, and both ends are fixed to intermediate portions of the left and right end ribs 6 and 7. A large number of needle-like discharge electrodes 18 are implanted at regular intervals in the length direction of the electrode holder 17 (length direction of the air outlet 2).

  Further, two ground electrodes 19 and 20 that are also metal round bars pass through the intermediate ribs 8, 9, and 10, and both ends are fixed to the intermediate portions of the ribs 6 and 7 at both the left and right ends. The ground electrodes 19 and 20 are parallel to each other and are also parallel to the electrode holder 17 so as to be equidistant from the discharge electrode 18. The positional relationship between the axes of 20 is such that the electrode holder 17 is the apex of an isosceles triangle, and the two ground electrodes 19 and 20 are both end points of the base of the isosceles triangle.

  Since the electrode unit 3 is configured as described above and the rotating frame 12 is supported as described above, the electrode unit 3 is in the standing posture as shown in FIGS. 6 and 7, that is, with the shafts 13 and 14 as fulcrums. When the ribs 6, 7, 8, 9, and 10 are in the upright posture, the electrode unit 3 is in a storage position in which it is stored in the housing 1, and is stably held in this storage position. At this time, the discharge electrode 18 is horizontal and its tip (needle tip) is directed toward the center line of the outlet 2, and the two ground electrodes 19, 20 are parallel to the top and bottom in front of the tip of the discharge electrode 18. It becomes. The distance between the ground electrodes 19 and 20 is such that a finger cannot be inserted between them and the tip of the discharge electrode 18 cannot be touched.

  Further, at this time, as shown in FIG. 9, the power supply unit 21 installed in the housing 1 is installed on the lower side of the air outlet 2 so that a high voltage can be supplied to the discharge electrode 18 through the electrode holder 17. The microswitch 22 is turned on when the switch actuator 22a is pressed by one of the intermediate ribs 8, 9, 10 such as the rib 10.

On the other hand, when the rotation frame 12 is rotated from this state and the electrode unit 3 is tilted forward as shown in FIGS. 4 and 10, the electrode unit 3 is switched to the take-out position that goes out from the blowout port 2. At this time, since the discharge electrode 18, the electrode holder 17, and the ground electrodes 19 and 20 are located outside the housing 1, they can be easily cleaned. Further, as shown in FIG. 11, the rib 10 is separated from the switch actuator 22a and the microswitch 22 is turned off, whereby the power supply to the discharge electrode 18 is cut off.
A reed switch or an optical sensor may be used instead of the micro switch.

  As described above, this blower type ion generator uses two blowers 4 and 5, but as shown in FIGS. 2 to 4, these blowers 4 and 5 are separated from the rear plate 1 b of the housing 1 to the left and right. The outside air is sucked from the intake grilles 4a and 5a provided on the rear plate 1b and blown simultaneously. These blowers 4 and 5 perform the air blowing from the outlet 2 on the average in the length direction thereof, so that the rotation directions of the fans 4b and 5b are opposite to each other.

  For the same purpose, left and right wind direction plates 23 and 24 extending obliquely toward the left and right ends of the air outlet 2 are disposed on the left and right outer sides of the installation positions of the blowers 4 and 5.

  In the above embodiment, since the blower outlet 2 is horizontally long, the whole is horizontally long. However, the blower outlet 2 may be vertically long, and its shape is not limited. In addition, the blow type ion generator of the present invention is not only used for static elimination but also used for charging and sterilization.
