Description

  The present invention relates to an ion blower that sends ionized air straight forward, and in particular, extends the reach of ions by causing the air ionized by the air feed-type ion blower to go straight in the outer shell of the ion blower, and is a long distance However, it relates to technology that can remove static electricity.

  Conventional air delivery type ion blowers were equipped with a fan to generate wind, but since the fan relied solely on the rotating blades, ionized air flowed straight through the outer shell of the ion blower at a constant density. Without it, as shown in FIG. Accordingly, since there is a portion where air does not flow, the outer shell of the ion blower is not effectively used. As a result, it is difficult to remove static electricity over a long distance because the reach distance of ions is short. There has been another problem that turbulence is generated by moving the air blown from the blowout port of the outer shell of the ion blower toward the charged body.

  In addition, the conventional air delivery type ion blower has no function of controlling the blowing angle of ionized air. The air was only blown at a fixed angle set by the manufacturer, and therefore it was difficult to effectively remove static electricity. This is because it was difficult to adjust the blow angle required for each industrial field.

  Furthermore, as a result of neutralization of + ions and − ions in the process of moving the ionized air by the fan in the outer shell of the ion blower, the ions moving to the charged body are reduced, so that the efficiency of removing static electricity is reduced.

  The prior art type ion blower has no device for removing minute dust in the outer shell of the ion blower or the air duct, so there is also a problem that fine dust particles adhere to the charged body and the fan. It was.

  An object of the present invention is to provide an ion blower that can solve the above-described various problems of the prior art and sends ionized air in a straight line.

  Other objects and advantages of the present invention will become apparent upon reading the detailed description and upon reference to the accompanying drawings.

  FIG. 2 is a block diagram showing the entire structure of an ion blower that sends ionized air based on corona discharge in a straight line according to the present invention, and FIG. 3 is a detailed block diagram of FIG. 2 and 3 are for explaining the concept of the present invention, and there may be various modifications different from the examples in these drawings. Also in the figure, the control lines between the elements and the connection of the power supply lines are not shown in detail, but this detail is well known not directly related to the present invention, so the spirit of the present invention is impaired. The creativity of the present invention is not denied.

  Roughly speaking, the present invention includes a control unit (60), a filter unit (70), a fan (20), a blower unit (90), a peripheral unit (30), and an ion generation unit (40). When ions are generated in the ion generation unit (40), the fan (20) operates according to the control of the control unit (60), and the ionized air in the ion blower outer shell (80) moves to the blower unit (90). , It is blown out again to the charged body (10). The peripheral unit (30) includes a data communication terminal (32) between internal / external data of the blower, a direct current power supply unit (34) for supplying direct current to the inside, and an operation display LED (36).

  The overall structure of the present invention is the same as a general air delivery type ion blower. The most characteristic part of the present invention is the fan (20). That is, unlike the prior art, in the present invention, in order to prevent the deviation of ionized air in the outer shell of the ion blower, in particular, the deviation on the outside of the outer shell of the ion blower, the stationary blade (24) is attached. As a result, the air flow in the outer shell of the ion blower becomes constant, and the air goes straight. In the prior art, as shown in FIG. 1C, there was a portion where air did not flow sufficiently due to the rotating blades, so the outer shell of the ion blower was not used effectively, but in the present invention, as shown in FIG. In addition, by attaching the fixed blade (24), the distribution of air in the ion blower outer shell (80) becomes constant, and the degree of accumulation of ionized air becomes higher than in the prior art. Therefore, the ions move far and the operating distance is extended as a result. FIG. 4 is a sectional view of an ion blower outer shell (80) used in the ion blower (1000) according to the present invention.

  The fixed vane (24) can be mounted just behind the rotary vane (22) or at some distance. Further, the position of the electrode (46) can be variously determined as necessary, for example, at the front part of the rotary blade, between the rotary blade and the fixed blade, or at the rear part of the fixed blade.

  FIG. 5 is an explanatory diagram of mounting a blower unit (when a long working distance and a narrow working range are required) of the ion blower according to the present invention, and FIG. 6 is a diagram showing a short working distance and a wide operation of the ion blower according to the present invention. It is explanatory drawing of ventilation unit attachment (when a range is required). The air blowing unit in FIG. 5 is used when the operating distance is long and the wind goes straight because the direction of the air blowing angle controller (93) and the direction of air are the same. The blower unit in FIG. 6 is used when the operating distance is short. In this case, the air blowing angle controller (93) is wide open, and the air does not move far. The wind direction controller (94) controls the wind direction by tilting the main body of the blower or by controlling the inner blades perpendicular to the direction of the air blowing angle controller.

  The present invention includes a filter unit (70) for removing dust in the air near the air inlet.

  FIG. 7 is an explanatory diagram of an embodiment of the assembly duct unit of the ion blower according to the present invention. As shown in FIGS. 8 and 9, in one embodiment of the present invention, all elements of the present invention are housed in the outer shell (80), and the main body of the ion blower (1000) is installed on a desk or a floor. The pedestal (92) supports the blower body so that it can. The platform (92) is integrated via the outer shell and a manual tilt control lever (96), and this tilt control lever (96) functions as a wind direction controller (94). Therefore, the overall wind direction of the ion blower is controlled by tilting the front part of the ion blower to an arbitrary angle and then turning the tilt control lever (96) to the right to fix the tilt of the main body of the ion blower. Is done. In this embodiment, only the manual tilt control lever (96) has been described. However, replacing this with an electric tilt control lever means that the electric tilt control lever corresponds to the equivalent of the manual tilt control lever. Included in the category.

  In FIG. 7, the discharge needle (46) can be easily removed by the socket bracket (46a), and the socket bracket is attached to the inside of the duct (82) via the needle socket (46b).

  8 and 9 are embodiments of the ion blower according to the present invention. The embodiment of FIG. 8 has a carrying handle (98), but the embodiment of FIG. 9 does not.

  On the other hand, when the ion blower according to the present invention is operated, dust in the air is filtered by a filter unit attached to the suction port of the outer shell of the ion blower before being sucked into the outer shell of the ion blower. Thereafter, when a high voltage is applied to the electrode from the high voltage unit, air is ionized at the electrode, and + ions and − ions are generated. The ionized air is moved to the outlet of the outer shell of the ion blower by the rotating blades. The turbulent air flow formed by the shape of the blades of the rotating blades is changed into a laminar air flow by a fixed blade having a shape corresponding to the turbulent air flow, and the air is sent out toward the charged body. The air blowing angle is controlled by the air blowing angle controller according to the distance to the charged body, and air is discharged from the blowing port. A wind direction controller is used to control the overall wind direction of the ion blower. By doing so, static electricity can be effectively removed.

  While the invention may be modified and practiced in various forms in addition to the embodiments described above, this specification has described and described specific embodiments thereof. However, the invention is not limited to the specific forms described above, but includes all modifications, equivalents and alternatives within the spirit and scope of the invention as defined in the appended claims. Please understand that.

  By implementing the present invention, the following effects can be obtained.

  First, since the ionized air flow generated by the air delivery type ion blower is compensated by the fixed blades and travels straight in the outer shell of the ion blower, the ionized air released from the ion blower forms a laminar flow to the charged body To increase the ion concentration of ionized air.

  Second, since the ionized air can be blown widely, it is possible to remove static electricity from the charged body having various surface shapes.

  Third, the ion blower can be installed in various processes such as LCD / PDP modules, semiconductors, films, printing, painting, medical, and food.

  Fourth, when the ionized air generated by this ion blower is released, by controlling the air blowing angle and the wind direction, it is possible to obtain the necessary blowing angle and wind direction for each charged body. The electricity can be removed.

  Fifth, the efficiency of removing static electricity is improved because the decrease in the amount of generated ions due to neutralization of + ions and-ions in the outer shell of the ion blower when ionized air is moved by the fan is improved. The

  Sixth, since the filter unit attached to the suction port of the outer shell of the ion blower removes the fine dust in the outer shell of the ion blower, the fine dust particles hardly adhere to the fan and the charged body.

[Mode of the Invention]
[Ion blower that sends ionized air straight forward based on AC corona discharge]
The basic structure and operation principle of an ion blower that sends ionized air based on an AC corona discharge straight forward are the same as those of an ion blower that sends ionized air straight based on a DC corona discharge. Since the ion blower uses alternating current instead of direct current when generating a high voltage, only the alternating current characteristic is the difference. Therefore, only different parts will be referred to, and redundant description of the same parts will be omitted. The principle of operation of a general AC air delivery type ion blower used in the present invention is described in detail in Korean Patent No. 512137 of the applicant.

  The pulse AC type is also included in the AC type of the present invention. The most different parts of these two types are the high voltage generating part and the discharge electrode. In the AC type, only one high voltage cable is required because of the AC characteristics. While the voltage is a positive value, the electrode functions as a positive discharge electrode and generates ions corresponding thereto, and while the voltage is a negative value, the electrode functions as a negative discharge electrode and generates ions accordingly. Unlike the DC type, only one high voltage unit is required, and the + electrode and the − electrode are not required separately. Instead, a ground electrode is used to induce ion generation.

  Since no + high voltage cable and -high voltage cable are required separately, only one ion balance sensor is required, which surrounds the high voltage cable between the high voltage unit and the electrode. And senses the voltage value derived from the high voltage cable.

  The AC type CPU controls the overall ion generation balance by controlling the amount of positive ions and negative ions generated in accordance with the high voltage frequency and the set value of the duty ratio.

  The description of the control unit is omitted because the basic structure is the same although the internal structure is slightly different.

Furthermore, in the ion blower that sends ionized air straight forward according to the present invention, when the ion blower is a DC type, the electrode is configured for + and-, and the high voltage unit is used for + and- The high voltage cable is configured for + and-, the balance of ion generation is controlled by the CPU, the CPU inputs the value of the amplifier, compares it with the standard value, When the value is smaller than the standard value, an imbalance between positive ions and negative ions due to electrode contamination is determined, and the high voltage is set to be the same as the set value by raising the value smaller than the standard value. If the controller is commanded so that the electrodes that are considered contaminated will generate more ions, and conversely, if the value of the amplifier is greater than the standard value Determine the imbalance between positive and negative ions due to electrode contamination and command the high voltage controller to lower the value greater than the standard value to be equal to the set value, resulting in contamination The electrode that is considered to generate a small amount of corresponding ions.
