<TECHNICAL FIELD OF THE INVENTION

This invention relates to the ion blower of a linear blowing system. In particular, the present invention relates to a technology that allows ionized air in a blown type ion blower to move straight in an ion blower enclosure, thereby improving ion reach and allowing long distance static elimination.

<Prior art in this field>

Conventional blower type ion blowers have fans for generating wind, but these fans rely solely on the rotor blades so that ionized air does not flow straight to uniform density within the ion blower enclosure and is directed or spread in one place as shown in FIG. The phenomenon occurred that the air flows in the ion blower enclosure is not possible to use the ion blower enclosure is not effectively used as a result of this shortened the reach of the ions it was difficult to long-distance static elimination. In addition, there is a problem that air output from the outlet of the ion blower enclosure is delivered in a turbulent flow toward the charging object.

In addition, the conventional blower type ion blower does not have a function of adjusting the injection angle of the ionized air. Since air is injected only by the injection angle set at the time of manufacture by the manufacturer, it is difficult to meet the requirements of the injection angle required for each site, which makes it difficult to effectively eliminate static electricity.

In addition, conventionally, the ionization of air by the fan (fan) in the process of moving to the charging object in the ion blower enclosure has a problem that the neutralization of + and-ions occurs to reduce the amount of ions reaching the charged object to reduce the static elimination efficiency .

In addition, there is no conventional device for removing the fine dust in the ion blower enclosure or air duct has a problem that the fine dust particles are attached to the charging object and the fan blade.

<Preferred Example 2: Ion blower of the linear blowing method based on the corona discharge of the AC method>

The linear blower type ion blower based on AC corona discharge is basically the same in construction and operation principle as the ion blower type of linear blower based on corona discharge of DC type. However, in case of high voltage, AC is used instead of DC so only the parts according to the characteristics of AC are different. Therefore, in this embodiment, only different parts are mentioned and repeated descriptions of the same parts are omitted. The operation principle of the general AC blower type ion blower employed in the present invention is described in detail in Patent No. 512137, the applicant's registered patent.

In particular, the AC method of the present invention should be interpreted as including the PULSED-AC method. The most different part of the two methods is the part related to the high voltage generating part and the discharge electrode. In the AC method, only one wire is required for the high voltage line due to the characteristics of the AC. Thus, while the voltage has a positive value, the electrode acts as a positive discharge electrode and generates ions accordingly, while the negative electrode acts as a discharge electrode and generates corresponding ions. Unlike the direct current method, in the AC method, only one high voltage generator is required, and the electrode does not need to have a + electrode and a-electrode separately. Instead, a ground electrode is used to induce ion generation.

Since the high voltage line does not need to be + and −, only one ion balance sensor is installed around the high voltage line between the high voltage generation unit and the electrode to sense a voltage value induced from the high voltage line.

In the AC system, the CPU controls the amount of cations and anions generated in accordance with the set value of the frequency and duty ratio of the high voltage to adjust the balance of ion generation as a whole.

In addition, the internal configuration of the control unit is slightly different, but basically the same configuration, so a description thereof will be omitted.

<Operation Principle of the Invention>

FIG. 2A is a block diagram showing an embodiment of the entire configuration of the ion blower of the linear blowing method based on corona discharge according to the present invention, and FIG. 2B is a detailed block diagram of FIG. 2A. 2 is intended to explain the concept of the present invention, and various modifications are possible unlike the example of this drawing. Although the connection part of the control line and the power line between each component is not shown in the drawings in detail, it belongs to a general free technology and is not directly related to the present invention, and the omission of this part does not detract from the spirit of the present invention. It is to be understood that the integrity of a person is not denied.

The structure of this invention is largely comprised of the control part 60, the filter part 70, the fan 20, the discharge part 90, the peripheral part 30, and the ion generating part 40. As shown in FIG. When ions are generated in the ion generator 40, the fan 20 is driven by the control of the controller 60, and ionized air in the ion blower enclosure 80 is sent to the discharge unit 90, which in turn The charged object 10 is discharged. The peripheral portion 30 includes a terminal 32 for data communication with the inside and outside of the blower, a DC power supply portion 34 for supplying a direct current therein, and an LED 36 for operation display.

The overall configuration of this invention is the same as that of a general blow type ion blower. However, the most characteristic part of this invention is in the fan 20. That is, unlike the prior art, in the present invention, in order to prevent the ionized air from being concentrated to one side in the ion blower enclosure, in particular to the outside of the ion blower enclosure, a fixed blade 24 is installed separately from the rotor blade 22 to flow the air. The ion blower enclosure is characterized in that it is compensated to be in a uniform and straight direction. In the prior art, there is a problem that the ion blower enclosure is not used efficiently due to a portion where air does not flow well by the rotor blade as in the portion C of FIG. 1, but in the present invention, the air distribution is improved by installing the fixed blade 24 as shown in FIG. Since the ion blower enclosure 80 is uniform, the concentration of ionized air may be greater than that of the related art, and thus ions may be sent to a far distance, resulting in an increase in the static charge distance. 3 shows a cross-sectional view of the ion blower enclosure 80 used in the ion blower 1000 according to the present invention.

At this time, the fixed blade 24 may be attached directly behind the rotary blade 22, or may be installed at a certain distance. In addition, the position at which the electrode 46 is installed can be variously set as necessary, such as the front end of the rotor blade, between the rotor blade and the fixed blade, and the rear end of the fixed blade.

Figure 4a is an illustration of the installation of the discharge portion of the ion blower according to the present invention (when long discharge distance and narrow static elimination range required), Figure 4b is an illustration of the installation of the discharge portion of the ion blower according to the present invention (short discharge distance and wide static elimination On request). In the case of Figure 4a is used in the case of a long static discharge distance, the air injection angle adjuster 93 shows an example in which the wind is to go straight to be horizontal to the direction of the air coming out. On the other hand, Figure 4b shows an example in the case of a short static distance. At this time, the air injection angle controller 93 is extended outward so that air is not sent far. The wind direction controller 94 adjusts the direction of the wind direction by various methods such as adjusting the wind direction by tilting the blower body as a whole, or manipulating the wind direction by manipulating the inner wing in a direction perpendicular to the air blowing angle controller. do.

And in this invention, the filter part 70 is provided in the air inlet part for removing the dust etc. in air.

On the other hand Figure 5 shows an embodiment of the assembly duct portion of the ion blower according to the present invention. In one embodiment of the present invention, as shown in FIG. 6, the components of the present invention are accommodated in the enclosure 80, and the pedestal 92 supports the body of the ion blower 1000 to be mounted on a table or floor. Play a role. And the pedestal 92 is coupled to the enclosure and the manual tilt adjustment lever 96, the tilt adjustment lever 96 serves as a wind direction controller 94. Therefore, the front of the ion blower is inclined at an arbitrary angle, and then the upper tilt adjusting lever 96 is turned to the right to fix the tilt of the ion blower body to adjust the course of the overall wind direction of the ion blower. Although only the manual tilt adjustment lever 96 has been described herein, the electric substitution is equivalent to the equivalent of the present invention and is included in the scope of the spirit of the present invention.

5, the discharge needle 46 is easily detachable by the socket bracket 46a, and the socket bracket is coupled to the inside of the duct 82 via the needle socket 46b.

6 shows an embodiment of an ion blower according to the present invention. FIG. 6A has a carrying handle 98 to facilitate carrying of the ion blower, and FIG. 6B does not have a carrying handle.

On the other hand, when the ion blower according to the present invention operates, dust that may be in the air is pre-filtered by a filter unit installed at the ion blower enclosure suction side, and then sucked into the ion blower enclosure, and then a high voltage is generated by the high voltage generator. When applied to the electrode, air is ionized at the electrode to generate + and-ions. Ionized air is directed by the rotor blades to the outlet of the ion blower enclosure. In the next stage of the rotor blade, the air flow in the form of turbulence formed according to the shape of the blade of the rotor blade is converted into a laminar flow type air flow by the corresponding fixed blade and is discharged toward the charged object. On the outlet side, the air is blown out by adjusting the spray angle in accordance with the remote charging object or the near charging object by the air spray angle controller. In addition, the wind direction controller is used to control the overall wind direction of the ion blower. In this way, efficient static elimination is possible.

In addition to the above embodiments, the present invention may be variously modified and may take various forms, and only the specific embodiments thereof are described in the detailed description of the present invention. It is to be understood, however, that the present invention is not limited to the specific forms mentioned in the detailed description of the invention, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims. It should be understood to do.

The practice of this invention has the following effects:

First, the flow of ionized air generated in the blower type ion blower is compensated by the fixed blades and goes straight in the ion blower enclosure, so that ionized air discharged from the ion blower is transferred to the charged object in the form of laminar flow, and ionization. The concentration of ions contained in the compressed air is increased.

Second, by controlling the air injection angle and the wind direction when the ionized air generated by the ion blower is discharged, it is possible to obtain the injection angle and the wind direction required for each charged object, thereby enabling efficient static elimination.

Third, the amount of ions generated by the neutralization of + and − ions inside the ion blower enclosure during movement of the ionized air by the fan can be prevented from being reduced, thereby improving the static elimination efficiency.

Fourth, because the filter unit installed in the suction portion of the ion blower enclosure removes the fine dust in the ion blower enclosure, there is less fear that fine dust particles will adhere to the fan and the charging object.
