  However, in a cleaning device equipped with a device for generating ions or an electrostatic atomizer, when the operation of the cleaning device takes a relatively long time, etc., ions or charged particulate water (hereinafter referred to as ions and charged particulate water) Are collectively referred to as charged particles), the path through which air flows and dust in the cleaning device are charged to the same polarity as the charged particles. As a result, the supplied charged particles are repelled by the Coulomb force against the air flow path and dust, so that the effects such as sterilization of the charged particles are not sufficiently exhibited.

  Accordingly, an object of the present invention is to provide a cleaning device provided with a charged particle generator, which can sufficiently exhibit the desired effect of the charged particles generated by the charged particle generator. It is.

  The cleaning device according to the present invention includes a blower, a dust collector, a suction port, a pipe, a charged particle generator, a detector, and a control unit. The pipe connects the dust collector and the suction port. The charged particle generator generates charged particles containing ions or charged fine particle water. The detector detects dust flowing through the inside of the pipe. The control unit controls the charged particle generator. When the dust is detected by the detector, the control unit controls the charged particle generator so that the charged particles are mixed with the air flowing through the pipe by the operation of the blower.

  According to the present invention, when the dust is detected by the detector, the charged particle generator is controlled so that the charged particles are mixed with the air flowing through the pipe. The charged particles can be supplied to neutralize the potential of the pipe or neutralize the potential of the dust so that the dust does not adsorb to the dust collector. Therefore, even when the cleaning device is operated for a relatively long time, the charged particles can prevent the pipe and dust from being charged to the same polarity as the charged particles. In this way, the effects such as sterilization of the charged particles can be sufficiently exhibited.

  By doing in this way, it is a cleaning device provided with a charged particle generator, and provides a cleaning device which can fully exhibit the desired effect which the charged particles which a charged particle generator generates have. it can.

  In the cleaning device according to the present invention, the charged particle generator is disposed in the suction port. The charged particle generator generates positive charged particles and negative charged particles. The control unit controls the charged particle generator so that positively charged particles and negatively charged particles are generated simultaneously.

  According to this configuration, when air sucked from the suction port body and dust flow through the pipe, charged particles having different polarities can be mixed with the air at the same time. Therefore, when air containing dust flows through the pipe, the dust can be electrically neutralized by charged particles having a polarity opposite to that of the charged dust, and the polarity opposite to that of the charged pipe. The charged particles can neutralize the pipe electrically. Moreover, it can suppress that dust adsorb | sucks to piping and a dust collector because dust is neutralized electrically and piping is neutralized electrically. Thus, according to this configuration, when dust is detected, the potential of the dust and the potential of the pipe can be effectively neutralized by the charged particles having the positive potential and the charged particles having the negative potential. The effect of sterilization and the like of the charged particles can be sufficiently exhibited.

  In the cleaning device according to the present invention, the charged particle generator is disposed in the suction port. The charged particle generator generates positive charged particles and negative charged particles. The control unit controls the charged particle generator so that positively charged particles and negatively charged particles are alternately generated.

  According to this configuration, when dust is detected, positively charged particles and negatively charged particles are alternately sent to the inside of the pipe until the dust is collected by the dust collector. Can do. When, for example, positively charged particles are sent to the pipe from the time when dust is detected, the positively charged particles are adsorbed to the pipe charged to a negative potential. Thereby, in the inside of piping, it will be in the state where the polarity of piping maintains neutrality or a positive potential. Therefore, while dust moves inside the pipe, dust charged to a positive potential is repelled and it is possible to suppress the dust from adhering to the pipe.

  On the other hand, the negatively charged particles can neutralize the positive charge remaining in the pipe and neutralize the positive potential dust collected in the dust collector. Moreover, a sterilization effect can be exhibited by adsorbing negatively charged particles to dust. In addition, since dust charge and dust collector charge are removed, it is difficult for the dust collector to adsorb dust. Therefore, the dust collected in the dust collector can be easily discarded.

  Thus, according to this configuration, when dust is detected, the charging of the dust or the pipe by the charged particles of one polarity sent out earlier is charged by the charged particles of the other polarity sent out later. Can be neutralized. In this way, every time dust is detected, positively charged particles and negatively charged particles can be alternately sent to the inside of the pipe, so that the dust potential and the pipe potential are It can neutralize effectively.

  In the cleaning device according to the present invention, the control unit controls the charged particle generating device so that the timing when the positively charged particles and the negatively charged particles are generated is switched every predetermined period.

  According to this configuration, the charged particle generator can switch between positively charged particles and negatively charged particles when a predetermined time has elapsed. When dust is detected, positively charged particles and negatively charged particles are alternately sent to the inside of the pipe alternately at predetermined intervals, so that the dust potential and the pipe potential are charged by the charged particles. It can neutralize effectively.

  In the cleaning device according to the present invention, the control unit generates positive charged particles and negative charged particles depending on whether the dust is detected by the detector or if the dust is not detected by the detector. The charged particle generator is controlled so as to be generated alternately.

  According to this configuration, the charged particle generator can switch between positively charged particles and negatively charged particles depending on whether dust is detected or when dust is not detected. According to this configuration, one charged particle is sent into the pipe every time dust is detected, and the other charged particle is sent into the pipe every time dust is no longer detected. And negatively charged particles can be alternately and repeatedly sent into the pipe, so that the dust potential and the pipe potential can be effectively neutralized by the charged particles.

  In the cleaning device according to the present invention, the charged particle generation device includes a first charged particle generation unit disposed in the suction port body, and a first disposed in the pipe between the suction port body and the dust collector. 2 charged particle generators. The control unit alternately generates positive charged particles and negative charged particles by the first charged particle generation unit, and has a polarity opposite to the polarity of the charged particles generated by the first charged particle generation unit. The first charged particle generator and the second charged particle generator are controlled so that the second charged particle generator generates alternating charged particles alternately.

  According to this configuration, when the first charged particle generation unit generates positive charged particles, for example, from the time when dust is detected, the positive charged particles are not adsorbed to the dust charged to the positive potential. On the other hand, in this case, charged particles having a positive potential are adsorbed to the pipe charged to a negative potential. As a result, the piping is always kept electrically neutral or has a positive potential. Therefore, the dust flows through the pipe while repelling each other, and dust charged to a positive potential is repelled from the pipe while flowing through the pipe. Thus, according to this structure, it can suppress that dust adheres to piping upstream from the position where the 2nd charged particle generation | occurrence | production part is arrange | positioned.

  On the other hand, when the second charged particle generator generates negative charged particles, for example, from the time when dust is detected, the dust is further downstream than the position where the second charged particle generator is disposed. The negatively charged particles are sterilized by being adsorbed, and are electrically neutralized or charged to a negative potential. On the other hand, since the pipe is charged with a negative potential downstream from the position where the second charged particle generation unit is disposed, the electrically neutralized dust or the dust charged with a negative potential does not enter the pipe. Repelled. Therefore, it is possible to suppress the dust from adhering to the pipe even downstream from the position where the second charged particle generation unit is disposed.

  Since the first charged particle generator generates positive charged particles after generating positive charged particles, negative charged particles are adsorbed to dust charged to positive potential. Dust is sterilized by adsorbing negatively charged particles, and is electrically neutralized or charged to a negative potential. On the other hand, negatively charged particles are not adsorbed to the pipe charged to a negative potential. Moreover, while circulating through the piping, dust charged to a negative potential repels, and dust repels the piping charged to a negative potential. Thus, according to this structure, it can suppress that dust adheres to piping upstream from the position where the 2nd charged particle generation | occurrence | production part is arrange | positioned.

  On the other hand, since the second charged particle generator generates positive charged particles after generating negative charged particles, the dust that has passed through the position where the second charged particle generator is disposed is positive. The charged particles at the potential are electrically neutralized by being adsorbed to the dust or charged to a positive potential. Furthermore, dust is sterilized by the reaction of positively charged particles and negatively charged particles. Since the pipe is charged to a negative potential downstream from the position where the second charged particle generating unit is disposed, the charged particles having a positive potential are electrically neutralized by being adsorbed to the pipe or charged to a positive potential. To do. For this reason, it is possible to suppress the dust from adhering to the pipe even downstream of the position where the second charged particle generation unit is disposed.

  In this way, positively charged particles and negatively charged particles are alternately generated in the first charged particle generation unit, and the polarity is opposite to the polarity of the charged particles generated by the first charged particle generation unit. By repeating the generation of the charged particles having an alternating current in the second charged particle generating unit, the dust that has passed through the position where the first charged particle generating unit is disposed is transferred to the second charged particle generating unit. After passing through the position, the series of actions of being electrically neutralized and sterilized by charged particles of opposite polarity is repeated. By doing in this way, the dust collected by the dust collector can be accumulated in the electrically neutralized state and the sterilized state.

  In the cleaning device according to the present invention, the control unit includes the first charged particle generation unit and the second charged particle generation unit so that the timing at which the positive charged particles and the negative charged particles are generated is switched at predetermined intervals. The charged particle generation unit of the control.

  According to this configuration, when a predetermined time elapses, the first charged particle generation unit and the second charged particle generation unit switch and generate positive charged particles and negative charged particles. be able to. According to this configuration, the first charged particle generating unit sends one charged particle to the inside of the pipe when dust is detected, and sends the other charged particle to the inside of the pipe when a predetermined time elapses. Thus, the positively charged particles and the negatively charged particles can be alternately sent to the inside of the pipe every predetermined period. The second charged particle generation unit sends the other charged particle to the inside of the pipe when dust is detected, and sends the one charged particle to the inside of the pipe when a predetermined time elapses. Thus, the positively charged particles and the negatively charged particles can be repeatedly sent to the inside of the pipe every predetermined cycle. In this way, the dust potential and the piping potential can be effectively neutralized by the charged particles.

  In the cleaning device according to the present invention, the control unit generates positive charged particles and negative charged particles depending on whether the dust is detected by the detector or if the dust is not detected by the detector. The first charged particle generator and the second charged particle generator are controlled so that they are alternately generated.

  According to this configuration, the first charged particle generation unit and the second charged particle generation unit have a positive potential charged particle and a negative potential depending on whether dust is detected or not detected. It can be generated by switching between charged particles. According to this configuration, the first charged particle generation unit sends one charged particle to the inside of the pipe every time dust is detected, and puts the other charged particle into the pipe every time no dust is detected. By sending it out, positively charged particles and negatively charged particles can be alternately and repeatedly sent into the pipe. The second charged particle generation unit sends the other charged particle to the inside of the pipe every time dust is detected, and sends one charged particle to the inside of the pipe every time no dust is detected. The positively charged particles and the negatively charged particles can be alternately and repeatedly sent into the pipe. In this way, the dust potential and the piping potential can be effectively neutralized by the charged particles.

  In the cleaning device according to the present invention, the charged particle generation device includes a first charged particle generation unit disposed in the suction port body, and a first disposed in the pipe between the suction port body and the dust collector. 2 charged particle generators. The control unit generates a charged particle having a positive potential or a charged particle having a negative potential by the first charged particle generation unit, and is opposite to a polarity of the charged particle generated by the first charged particle generation unit. The first charged particle generation unit and the second charged particle generation unit are controlled so that the second charged particle generation unit generates charged particles having the polarities.

  According to this configuration, when the first charged particle generation unit generates positive charged particles, for example, from the time when dust is detected, the positive charged particles are not adsorbed to the dust charged to the positive potential. On the other hand, in this case, the positively charged particles are adsorbed to the negatively charged pipe, whereby the pipe is electrically neutralized or charged to the positive potential. For this reason, the dust flows through the pipe while repelling each other, and dust charged electrically at a positive potential is repelled from the pipe while flowing through the pipe. Thus, according to this structure, it can suppress that dust adheres to piping upstream from the position where the 2nd charged particle generation | occurrence | production part is arrange | positioned.

  On the other hand, when the second charged particle generator generates negative charged particles, for example, from the time when dust is detected, the dust is further downstream than the position where the second charged particle generator is disposed. The negatively charged particles are sterilized by being adsorbed, and are electrically neutralized or charged to a negative potential. On the other hand, since the pipe is charged with a negative potential downstream from the position where the second charged particle generation unit is disposed, the electrically neutralized dust or the dust charged with a negative potential does not enter the pipe. Repelled. Therefore, it is possible to suppress the dust from adhering to the pipe even downstream from the position where the second charged particle generation unit is disposed.

  As described above, according to the present invention, there is provided a cleaning device provided with a charged particle generator, which can sufficiently exhibit the desired effect of the charged particles generated by the charged particle generator. Can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
In FIG. 1, the vacuum cleaner 100 as an example of the cleaning apparatus which concerns on 1st Embodiment of this invention is shown. The vacuum cleaner 100 includes a main body 1, a suction port body 2, an extension pipe 3, a hand operating section 4, a hose 5, and a charged particle generator 6.

  As shown in FIG. 2, the main body 1 accommodates a blower 11, a dust collector 12, a filter 13, and a blower path 14. The housing forming the main body 1 is formed of, for example, ABS resin (acrylonitrile butadiene styrene copolymer) or the like in order to maintain a desired strength. The main body 1 is formed with a suction port 10a through which air and dust flow into the main body 1 and an exhaust port 10b through which air from which dust has been removed flows out of the main body 1.

  The air blowing path 14 includes a path that leads from the suction port 10a to the exhaust port 10b as a path through which air flows in the main body 1. The ventilation path 14 is a path that connects the blower 11, the dust collector 12, and the filter 13 inside the main body 1. Moreover, the ventilation path 14 contains the inside of the hose 5 (refer FIG. 1) and the inside of the suction inlet 2 (refer FIG. 4). The air blowing path 14 upstream of the suction port 10 a is formed by a pipe including the hose 5 and the suction port body 2.

  The cyclone type dust collector 12 has a cylindrical shape. The dust collector 12 is formed with a suction port 12 a for allowing air and dust to flow into the dust collector 12. The dust collector 12 also has an exhaust cylinder 12b for allowing the air from which the dust has been separated to flow out of the dust collector 12. The exhaust cylinder 12 b is disposed at the center of the dust collector 12 in the radial direction. The exhaust cylinder 12b extends substantially in the vertical direction. The direction in which the exhaust tube extends substantially coincides with the vertical direction of FIG.

  The blower 11 is a metal turbofan surrounded by a metal casing. The turbo fan rotates based on the rotation of an electric motor that can rotate at a high speed. The blower 11 has a characteristic that it is more resistant to pressure change than earning air. Air sucked by the blower 11 is sucked from the suction port 10 a of the main body 1 and flows into the dust collector 12 from the suction port 12 a of the dust collector 12.

  The air that has flowed into the dust collector 12 descends while rotating inside the dust collector 12, then rises inside the exhaust cylinder 12 b and flows out of the dust collector 12. Furthermore, air is sucked into the blower 11 via the filter 13 and then flows out of the main body 1 from the exhaust port 10b. Fine dust remaining in the air without being collected in the dust collector 12 is removed by the filter 13. Air purified by passing through the dust collector 12 and the filter 13 is discharged outside the main body 1.

  As shown in FIGS. 3 and 4, the suction port body 2 includes a connection pipe 20, an upper universal joint 21, a lower universal joint 22, a cylindrical joint 23, a casing 24, a bumper 25, and a rotating brush 26. . The connection pipe 20 is a connection part between the suction port body 2 and the extension pipe 3 (see FIG. 1). The inside of the suction port body 2 including the inside of the connection pipe 20 also forms a part of the blowing path 14.

  The housing 24 is a resin case. The housing 24 accommodates the rotating brush 26 in a rotatable manner. The bumper 25 is disposed in front of the housing 24 in order to reduce the collision between the housing 24 and furniture. Between the casing 24 and the connection pipe 20, the connection pipe 20 is configured to be connected to the casing 24 so as to be rotatable vertically and horizontally. Specifically, the connection pipe 20 can be rotated vertically and horizontally by the upper universal joint 21, the lower universal joint 22 and the cylindrical joint 23 arranged between the housing 24 and the connection pipe 20.

  Each of the upper universal joint 21 and the lower universal joint 22 has a hemispherical shape. The upper universal joint 21 and the lower universal joint 22 are fixed to the upper and lower sides of the connection pipe 20, respectively, so that the upper universal joint 21 and the lower universal joint 22 form a substantially spherical shape. On the other hand, the cylindrical joint 23 is inserted into the housing 24. The connection pipe 20 to which the upper universal joint 21 and the lower universal joint 22 are fixed is inserted into the cylindrical joint 23 and can rotate in the circumferential direction of the cylindrical joint 23. With such a configuration, a user of the vacuum cleaner 100 (see FIG. 1) freely obtains an angle for operating the suction port body 2 by rotating the connection pipe 20 up and down and left and right with respect to the housing 24. be able to. With such a configuration, the operability of the vacuum cleaner 100 (see FIG. 1) using the suction port body 2 can be improved.

  As shown in FIG. 5, the extension tube 3 is a resin tube constituted by a double tube, and has an outer tube 3 a and an inner tube 3 b. The extension pipe 3 is made of, for example, ABS resin (acrylonitrile butadiene styrene copolymer) or the like in order to maintain a desired strength. One end of the outer tube 3a is connected to the hand operating section 4, and the other end is formed with an end face obtained by cutting the circular tube. One end of the inner tube 3b is slidably inserted into the outer tube 3a. The other end of the extension tube 3 that forms the tip of the extension tube 3 is connected to the suction port body 2. The extension pipe 3 and the hand operation unit 4 each constitute a part of the pipe. The extension pipe 3 incorporates an electrical wiring (not shown). Electric power supplied from the main body 1 is transmitted to the suction port body 2 via the hand operation unit 4.

  As shown in FIG. 1, the hand operating unit 4 is connected to the extension pipe 3. The hand operating unit 4 is a handle for moving and operating the suction port body 2 to a target location. The hand operation unit 4 is provided with input means for electrically controlling the main body 1. As will be described later, as an example of input means, the hand operation unit 4 includes, for example, an operation ON / OFF switch 41, a strength changeover switch 42, a rotating brush switch 43, and a charged particle generator ON / OFF switch 44 (whichever Are also built in. The hand operation unit 4 is provided with a display unit 45 as output means.

  The hose 5 is a tube formed by winding a flexible resin film such as soft vinyl chloride spirally. The hose 5 has a built-in electric wire for electrically connecting the hand operating unit 4 and the main body 1 in the same manner as the extension pipe 3.

  When cleaning a room or the like using the electric vacuum cleaner 100 (see FIG. 1), the rotating brush 26 (see FIG. 4) of the suction port body 2 sweeps the floor surface while rubbing the floor surface. Dust is scraped out. Dust is sucked in through the connection pipe 20, the extension pipe 3 (see FIG. 1), and the hose 5 (see FIG. 1) by the air sucked from the gap between the suction mouth body 2 and the floor surface. It flows into the inside of the main body 1 (see FIG. 2). Dust that flows into the main body 1 together with air is collected by the dust collector 12. In this case, dust containing dust such as nylon, human hair, wool or cotton is charged to a positive potential by friction, and the resin tube such as the extension tube 3 or the hose 5 is charged to a negative potential. It has been known. For this reason, relatively large dust out of the dust sucked together with the air is conveyed to the dust collector 12 by the force of the wind. On the other hand, fine dust adheres to the inside of a resin tube such as the extension tube 3 or the hose 5.

  Below, the structure for preventing that fine dust adheres to the inner side of the resin-made pipe | tubes as piping, and the charged particle generator 6 are demonstrated. As shown in FIG. 1, in the vacuum cleaner 100, the charged particle generator 6 is disposed in the suction port body 2.

  As shown in FIG. 6, the charged particle generator 6 includes a main body 6a, a charged particle discharger 6b, and a charged particle discharger 6c. The charged particle emitting unit 6b includes a needle-like discharge electrode 61b and an induction electrode 62b. The charged particle emitting unit 6c includes a needle-like discharge electrode 61c and an induction electrode 62c. The induction electrodes 62b and 62c are sheet metals each having a hole. The needle-like discharge electrode 61b is disposed inside the main body 6a so that a straight line passing through the center line of the hole of the induction electrode 62b and a direction in which the tip of the discharge electrode 61b extends substantially coincide. Similarly, the needle-like discharge electrode 61c is disposed inside the main body 6a so that a straight line passing through the center line of the hole of the induction electrode 62c and a direction in which the tip of the discharge electrode 61c extends substantially coincide. . As described above, the charged particle emitting unit 6b and the charged particle emitting unit 6c have the same structure.

  The main body 6a contains a circuit that generates high-voltage electricity applied to the discharge electrodes 61b and 61c. The main body 6a is a housing that houses the discharge electrodes 61b and 61c, the induction electrodes 62b and 62c, and these circuits. In FIG. 7, an example of the circuit of the charged particle generator 6 is shown. In the circuit, a pulse signal is generated by AC electricity supplied from an external power source. The pulse signal is boosted by a high-voltage generating transformer to generate a high-voltage electric pulse. The generated high-voltage electric pulse is input to the discharge electrodes 61b and 61c via diodes. A positive electric pulse is applied to the discharge electrode 61b. A negative electric pulse is applied to the discharge electrode 61c. By applying high-voltage electricity to the discharge electrodes 61b and 61c, electricity is discharged in the spaces between the discharge electrodes 61b and 61c and the induction electrodes 62b and 62c, respectively. Positive charged particles are emitted from the discharge electrode 61b, and negative charged particles are emitted from the discharge electrode 61c.

In the charged particle generator 6, positive ions and negative ions are generated as charged particles. The positive ions are H ⁺ (H ₂ O) _m (m is an arbitrary natural number), and the negative ions are O ²⁻ (H ₂ O) _n (n is an arbitrary natural number). By such positive ions and negative ions, positive ions and negative ions attach to and bind to the surface of bacteria or fungi in the air, and the reaction that takes place causes hydroxyl radicals (.OH) or radicals that are active species. Hydrogen oxide (H ₂ O ₂ ) is generated, and bacteria or fungi can be sterilized by the oxidizing action.

  Moreover, the vacuum cleaner 100 (refer FIG. 1) is provided with the detector 7 (refer FIG. 4). As shown in FIG. 4, the charged particle generator 6 and the detector 7 are attached to a connection pipe 20. In the connecting pipe 20, through holes 20 a and 20 b are formed on the wall surface forming the air flow path 14 at a position facing the charged particle discharge portion 6 b and a position facing the charged particle discharge portion 6 c, respectively. The generated ions including positive ions and negative ions are sent into the connection pipe 20 through the through holes 20a and 20b by the action of the air flowing through the blower passage 14.

  The detector 7 detects dust flowing through the connection pipe 20 in the pipe. An example of the detector 7 is a small one that utilizes reflection of light. Since such a device is already widely used, it can be suitably used as the detector 7. A through hole 27 is formed in the wall surface of the connection pipe 20 at a position facing the detector 7. Thereby, dust contained in the air flowing through the connection pipe 20 can be detected.

  The vacuum cleaner 100 (see FIG. 1) includes a control device 15 (see FIG. 8) that controls the charged particle generator 6. Although not shown, the control device 15 is accommodated in the main body 1 (see FIG. 1). The control device 15 is configured to receive power supplied from the outside via a power cord (not shown) accommodated by the cord reel. As shown in FIG. 8, the control device 15 controls the charged particle generator 6, the blower 11, the rotating brush 26, and the display unit 45. An example of a detector as a part for detecting dust detected by the detector 7 is configured by the control device 15. The control device 15 is an example of a control unit that controls the charged particle generation device 6. The control device 15 has a timer 15a that measures time.

  The control device 15 controls the blower 11 and the like in response to a signal transmitted from the input means provided in the hand operation unit 4. The operation ON / OFF switch 41 is a means for instructing start and stop of the operation of the blower 11. The strength switching switch 42 is a means for selecting the suction strength by changing the rotational speed of the blower 11. The rotary brush switch 43 is a means for selecting start and stop of rotation of the electric rotary brush 26 disposed in the suction port body 2. The charged particle generator ON / OFF switch 44 is a means for instructing the start and stop of the operation of the charged particle generator 6. The display unit 45 displays the operation status of the electric vacuum cleaner 100 (see FIG. 1) or the details of the operation, or an alarm when the operation is abnormal.

  When the interior of the room or the like is cleaned using the electric vacuum cleaner 100 (see FIG. 1), the user operates each input means of the hand operating unit 4 (see FIG. 1) to give instructions for starting operation. Is input to the control device 15. In response to an instruction issued from the control device 15, the blower 11 starts to rotate. Further, according to an instruction issued from the control device 15, the rotating brush 26 rotates in response to driving of a driving device (not shown) such as a motor. Dust containing dust is scraped from the floor surface by the rotation of the rotating brush 26 or the suction force generated by the blower 11. The dust, together with the air sucked from the gap between the suction port body 2 (see FIG. 4) and the floor, passes through the connection pipe 20 (see FIG. 4) and the extension pipe 3 and the hose 5 (both see FIG. 1). After being moved, the dust is collected in the dust collector 12 (see FIG. 2).

  In accordance with an instruction issued from the control device 15, the charged particle generator 6 generates positive ions and negative ions as charged particles simultaneously while the blower 11 is rotating. At this time, positive ions and negative ions are generated at a cycle of several hundred Hz. The positive ions and the negative ions are released into the connection pipe 20, and the positive ions and the negative ions are mixed with the air sucked into the main body 1 at the same time. While dust flows along the air blowing path 14 together with air, negative ions are adsorbed to dust charged to a positive potential, and positive ions are adsorbed to a resin tube such as the extension tube 3 or the hose 5 charged to a negative potential. . In this way, during operation of the vacuum cleaner 100, the resin tube and dust are always electrically neutral, so that the air flow path 14 from the suction port body 2 to the dust collector 12 is maintained. The adhesion of dust is suppressed. Further, at the same time when negative ions adhere to the positively charged dust and the dust is electrically neutralized, the dust is sterilized by the negative ions or by the reaction between the negative ions and the positive ions.

  In the vacuum cleaner 100, the control device 15 includes a charged particle generation device so that, when dust is detected by the control device 15, positive ions and negative ions are mixed with the air flowing through the connection pipe 20. 6 is controlled. As shown in FIG. 9, the control device 15 distinguishes between a case where the charged particle generator 6 generates positive ions and negative ions and a case where the charged particle generator 6 stops operating. 6 is controlled. Specifically, the control device 15 causes the charged particle generator 6 to operate when the dust is not detected, such that the charged particle generator 6 generates positive ions and negative ions when the dust is continuously sucked in. The charged particle generator 6 is controlled so as to stop. By doing in this way, the dust sucked from the suction port body 2 can be collected by the dust collector 12 after being sterilized by ions as charged particles each time.

  As described above, the vacuum cleaner 100 includes the blower 11, the dust collector 12, the suction port 2, the pipe including the hose 5 and the suction port 2, the charged particle generator 6, and the detector 7. And a control device 15. The pipe connects the dust collector 12 and the suction port 2. The charged particle generator 6 generates positive ions and negative ions as charged particles. The detector 7 detects dust flowing through the inside of the pipe. The control device 15 detects dust detected by the detector 7. The control device 15 controls the charged particle generator 6. Moreover, the control apparatus 15 controls the charged particle generator 6 so that charged particles are mixed with the air flowing through the piping by the operation of the blower 11 when dust is detected.

  According to the vacuum cleaner 100, when the control device 15 detects dust, the charged particle generator 6 is controlled so that positive ions and negative ions are mixed with the air flowing through the pipe. By supplying positive ions and negative ions to neutralize the potential of the pipe or neutralize the potential of the dust so that the dust does not adsorb inside the pipe and the dust collector 12 does not. Can do. Therefore, even when the operation of the vacuum cleaner 100 is performed for a relatively long time, it is possible to prevent the pipe and dust from being charged to the same polarity as the positive ion or the negative ion due to the positive ion and the negative ion. it can. In this way, the effects of sterilization and the like possessed by ions can be sufficiently exhibited.

  Thus, the vacuum cleaner 100 is a cleaning device provided with the charged particle generator 6, and can sufficiently exhibit the desired effect of positive ions and negative ions generated by the charged particle generator 6. it can.

  The charged particle generator 6 is disposed in the suction port body 2. The charged particle generator 6 generates positive ions and negative ions. The control device 15 controls the charged particle generator 6 so that positive ions and negative ions are generated simultaneously.

  According to this configuration, when air sucked from the suction port body 2 and dust circulate through the pipe, ions having different polarities can be mixed with the air at the same time. Therefore, when air containing dust circulates in the pipe, the dust can be electrically neutralized by ions having a polarity opposite to the polarity of the charged dust, and the polarity opposite to that of the charged pipe. The piping can be electrically neutralized by ions. Moreover, it can suppress that dust adsorb | sucks to piping and the dust collector 12 by electrically neutralizing dust and electrically neutralizing piping. As described above, according to this configuration, when dust is detected, the potential of the dust and the potential of the pipe can be effectively neutralized by the positive ions and the negative ions. Etc. can be sufficiently exerted.

  Note that examples of the charged particles generated by the charged particle generator 6 are not limited to positive ions and negative ions. For example, when ions are generated without specifying the ion species of positive ions and negative ions, the potential of the object to be attached can be removed or the ion balance in the space can be adjusted by the charge of the ions. can do.

  On the other hand, when the example of the generated ions is only negative ions, the negative ions can be charged to the positive charge of the object and the potential of the object can be removed, so that the bactericidal effect can be obtained at the same time. . On the other hand, when the example of the charged particles is charged fine particle water, it is possible to obtain a charge eliminating effect due to the charge of the charged fine particle water and a bactericidal effect due to the ions contained in the charged fine particle water.

  In addition, the charged particle generator 6 is not limited to being disposed in the suction port body 2, and may be disposed in the hand operation unit 4, the extension pipe 3, or the hose 5. Moreover, the charged particle generator 6 may be arrange | positioned in the suction inlet 10a of the main body 1, the suction inlet 12a of the dust collector 12, or these vicinity. Furthermore, the charged particle generator 6 may be disposed at any one of the above positions. However, even when the charged particle generator 6 is disposed at such a position, the control device 15 preferably controls the charged particle generator 6 as described above.

(Second Embodiment)
Below, the cleaning device which concerns on 2nd Embodiment is demonstrated using FIGS. In addition, below, the same code | symbol is attached | subjected to the structure which has the function similar to the structure of the vacuum cleaner 100 which is an example of the cleaning apparatus which concerns on 1st Embodiment, and the description is abbreviate | omitted.

  As described below, the cleaning device according to the second embodiment is different from the vacuum cleaner 100 as the cleaning device according to the first embodiment in that the charged particle generator 65 of the cleaning device according to the second embodiment. The structure of (refer FIG. 10) differs from the structure of the charged particle generator 6 of the vacuum cleaner 100 of 1st Embodiment. The charged particle generator 65 of the cleaning device according to the second embodiment is configured to generate positively charged particles and negatively charged particles separately. In addition, the charged particle generator 65 is arrange | positioned at the suction inlet 2 (refer FIG. 4) similarly to the charged particle generator 6 of the vacuum cleaner 100 of 1st Embodiment.

  As shown in FIG. 10, the charged particle generator 65 includes a main body 65a, a charged particle emitting unit 65b having a positive potential, and a charged particle emitting unit 65c having a negative potential. The charged particle emitting portion 65b and the charged particle emitting portion 65c have the same structure except for the circuit configuration. The charged particle emitting portion 65b and the charged particle emitting portion 65c include a needle-like discharge electrode 651b, a discharge electrode 651c, an induction electrode 652b, and an induction electrode 652c, respectively. The induction electrodes 652b and 652c are sheet metals each having a hole.

  The needle-like discharge electrode 651b is disposed inside the main body 65a so that a straight line passing through the center line of the hole of the induction electrode 652b and a direction in which the tip of the discharge electrode 651b extends substantially coincide. Similarly, the needle-like discharge electrode 651c is arranged inside the main body 65a so that a straight line passing through the center line of the hole of the induction electrode 652c and a direction in which the tip of the discharge electrode 651c extends substantially coincide. . The main body 65a is a housing that houses the discharge electrodes 651b and 651c, the induction electrodes 652b and 652c, and these circuits.

  As shown in FIG. 11, in the charged particle generator 65, two circuits are formed as a pulse generator including a high voltage transformer. In one circuit, the output of the high voltage transformer is connected to the discharge electrode 651b to generate positively charged particles. In the other circuit, the output of the high voltage transformer is connected to the discharge electrode 651c to generate negatively charged particles. One circuit and the other circuit each have a circuit selector switch 651a and a circuit selector switch 652a as switches for controlling the output.

  FIG. 12 is a control block diagram of the cleaning device according to the second embodiment. In the charged particle generator 65, the circuit selector switch 651a and the circuit selector switch 652a are switched by an instruction from the controller 15. The charged particle generator 65 can generate positively charged particles and negatively charged particles separately by switching the circuit changeover switches 651a and 652a. Although not shown, the charged particle generator 65 is disposed in the suction port 2 in the same manner as the charged particle generator 6 (see FIG. 1) of the vacuum cleaner 100 (see FIG. 1) of the first embodiment. Has been. Further, in the cleaning device according to the second embodiment, the charged particle generator 65 and the detector 7 are attached to the connection pipe 20 in the same manner as the electric vacuum cleaner 100 (see FIG. 1) of the first embodiment. Yes.

  In accordance with an instruction issued from the control device 15, the charged particle generator 65 alternately generates positive ions and negative ions as charged particles while the blower 11 is rotating. Positive ions and negative ions are released into the connection pipe 20 and mixed with the air sucked into the main body 1. As shown in FIG. 13, the control device 15 controls the charged particle generator 65 by distinguishing between a case where the charged particle generator 65 generates positive ions and a case where the charged particle generator 65 generates negative ions. To do. Furthermore, the control device 15 controls the charged particle generation device 65 so that the timing at which positive ions and negative ions are generated is switched every predetermined period.

  The predetermined period is set in advance based on the time measured in experiments or the like. The predetermined cycle is, for example, a time twice as long as the dust flowing through the pipe reaches the hand operating unit 4 from the suction port body 2. Further, for example, the predetermined period may be a time from dust to the hand operation unit 4 from the suction port body 2.

  Specifically, the control device 15 causes the charged particle generator 65 to generate positive ions for a predetermined time after the charged particle generator 65 generates positive ions so that the charged particles generator 65 generates positive ions from the time when dust is sucked. Further, the charged particle generator 65 is controlled so as to generate positive ions after the charged particle generator 65 continues to generate negative ions for a predetermined time. In the cleaning device according to the second embodiment, such an operation of the charged particle generator 65 is repeated until the control device 15 no longer detects dust.

  As described above, in the cleaning device according to the second embodiment, the charged particle generator 65 is disposed in the suction port body 2. The charged particle generator 65 generates positive ions and negative ions. The control device 15 controls the charged particle generator 65 so that positive ions and negative ions are generated alternately.

  According to this configuration, when dust is detected, positive ions and negative ions can be alternately sent to the inside of the pipe before the dust is collected by the dust collector 12. When positive ions are sent to the pipe from the time when dust is detected, the positive ions are adsorbed to the pipe charged to a negative potential. Thereby, in the inside of piping, it will be in the state where the polarity of piping maintains neutrality or a positive potential. Therefore, while dust moves inside the pipe, dust charged to a positive potential is repelled and it is possible to suppress the dust from adhering to the pipe.

  On the other hand, the negative ions can neutralize the positive charge remaining in the pipe and neutralize the positive potential dust collected in the dust collector 12. Moreover, a bactericidal effect can be exhibited by adsorbing negative ions to dust. In addition, since the charging of the dust and the charging of the dust collector 12 are removed, it is difficult for the dust collector 12 to adsorb the dust. Therefore, the dust collected in the dust collector 12 can be easily discarded.

  Thus, according to this configuration, when dust is detected, the charge of dust or piping due to the positive ions sent out earlier can be neutralized by the negative ions sent out later. In this way, every time dust is detected, positive ions and negative ions can be alternately and repeatedly sent into the pipe, so that the dust potential and the pipe potential can be determined by positive ions and negative ions. It can neutralize effectively.

  In the cleaning device according to the second embodiment, the control device 15 controls the charged particle generation device 65 so that the timing at which positive ions and negative ions are generated is switched at predetermined intervals.

  According to this configuration, the charged particle generator 65 can switch and generate positive ions and negative ions when a predetermined time has elapsed. When dust is detected, positive ions and negative ions are alternately sent to the inside of the pipe alternately at predetermined intervals, so that the dust potential and the pipe potential are effective by the positive ions and negative ions. Can be neutralized.

(Third embodiment)
Below, the cleaning device which concerns on 3rd Embodiment is demonstrated using FIG. In the following, the same reference numerals are used for the configuration of the vacuum cleaner 100 which is an example of the cleaning device according to the first embodiment and the configuration having the same function as the charged particle generator 65 of the cleaning device according to the second embodiment. A description thereof will be omitted.

  As will be described below, the cleaning device according to the third embodiment differs from the cleaning device according to the second embodiment in that the control device 15 uses the detector 7 to remove dust from the cleaning device according to the third embodiment. When dust is no longer detected after detection, the charged particle generator 65 (see FIG. 12) generates positive ions and negative ions by switching from positive charged particles to negative charged particles. Thus, the charged particle generator 65 is controlled.

  The cleaning device according to the third embodiment includes a charged particle generator 65 (see FIG. 11), similarly to the cleaning device according to the second embodiment. Similarly to the cleaning device according to the second embodiment, the charged particle generator 65 is disposed in the suction port body 2 (see FIG. 4).

  As shown in FIG. 14, in the cleaning device according to the third embodiment, the control device 15 includes a case where the charged particle generator 65 generates positive ions and a case where the charged particle generator 65 generates negative ions. The charged particle generator 65 is controlled in a distinct manner. Specifically, the control device 15 controls the charged particle generation device 65 so that positive ions and negative ions are alternately generated according to when dust is detected and when dust is not detected.

  Specifically, the control device 15 detects the dust while the charged particle generator 65 is generating positive ions so that the charged particle generator 65 generates positive ions from the time when the dust is sucked. The charged particle generator 65 is controlled so as to generate negative ions when it disappears, and to generate positive ions when dust is detected while the charged particle generator 65 generates negative ions. To do. In the cleaning device according to the third embodiment, such an operation of the charged particle generator 65 is repeated until the operation of the cleaning device is stopped.

  As described above, in the cleaning device according to the third embodiment, the control device 15 detects positive ions and negative ions depending on whether dust is detected by the control device 15 or when dust is not detected by the control device 15. The charged particle generator 65 is controlled so that ions are generated alternately.

  According to this configuration, the charged particle generation device 65 can switch between generating positive ions and negative ions depending on whether dust is detected or when dust is not detected. According to this configuration, positive ions are sent to the inside of the pipe every time dust is detected, and negative ions are sent to the inside of the pipe every time dust is no longer detected, thereby alternating positive ions and negative ions. Therefore, the dust potential and the piping potential can be effectively neutralized by positive ions and negative ions.

  Note that, in the cleaning device according to the third embodiment, the charged particle generator 65 is not limited to be operated so as to generate positively charged particles first, but the charged particle generator 65 is initially set to a negative potential. It may operate to generate charged particles.

  In the cleaning device according to the third embodiment, the length of time for discharging the positive charged particles is not the same as the time length for discharging the negative charged particles. Alternatively, there may be a situation in which electrification remains in the dust. However, even if charging remains in the extension tube 3 and the hose 5 or the dust or the like, the potential can be neutralized first by the charged particles of reverse polarity sent immediately after.

(Fourth embodiment)
Below, the cleaning device which concerns on 4th Embodiment is demonstrated using FIG. In the following description, the configuration of the vacuum cleaner 100 which is an example of the cleaning device according to the first embodiment and the configuration having the same function as the charged particle generator 65 of the cleaning device according to the second and third embodiments are the same. Reference numerals are assigned and explanations thereof are omitted.

  As will be described below, the cleaning device according to the fourth embodiment differs from the cleaning device according to the first, second, and third embodiments in that two charged particles are generated in the cleaning device according to the fourth embodiment. The apparatus 65 is arrange | positioned in the position between the suction inlet 2 and the dust collector 12 in piping, respectively. That is, the charged particle generation device of the cleaning device according to the fourth embodiment includes the charged particle generation device 65 arranged in the suction port body 2, the suction port body 2 (both see FIG. 4) and the dust collection in the blowing path 14. And a charged particle generator 65 disposed at a position between the container 12 (see FIG. 2).

  In FIG. 15, the vacuum cleaner 400 as an example of the cleaning apparatus which concerns on 4th Embodiment is shown. As shown in FIG. 15, in the vacuum cleaner 400, one charged particle generator 65 is disposed in the suction port 2, and one charged particle generator 65 is disposed in the hand operation unit 4. The charged particle generator 65 disposed in the suction port 2 is an example of a first charged particle generator, and the charged particle generator 65 disposed in the hand operation unit 4 is an example of a second charged particle generator. It is.

  In the vacuum cleaner 400, the control device 15 (see FIG. 12) is configured such that the charged particle generator 65 disposed in the suction port 2 alternately generates positive charged particles and negative charged particles, and In order for the charged particle generator 65 arranged in the hand operation unit 4 to alternately generate charged particles having a polarity opposite to the polarity of the charged particles generated by the charged particle generator 65 arranged in the suction port 2, Two charged particle generators 65 are controlled. That is, when the charged particle generator 65 arranged in the suction port 2 generates positive charged particles, the charged particle generator 65 arranged in the hand operation unit 4 generates negative charged particles. Let In addition, the control device 15 includes a charged particle generator 65 disposed in the suction port 2 and a hand so that the timing of generating positive charged particles and negative charged particles is switched every predetermined cycle. The charged particle generator 65 disposed in the operation unit 4 is controlled. The predetermined cycle is, for example, a time twice as long as the time for dust flowing through the pipe to reach the hand operating unit 4 from the suction port body 2. Further, for example, the predetermined period may be a time from dust to the hand operation unit 4 from the suction port body 2.

  The charged particle generator 65 disposed in the suction port 2 periodically generates positive charged particles or negative charged particles to mix charged particles with the air sucked into the suction port 2. The charged particle generator 65 disposed in the hand operation unit 4 generates positive charged particles or negative charged particles in the same cycle as the charged particle generator 65 disposed in the suction port 2, thereby allowing the hand operation. Charged particles are mixed in the air flowing through the inside of the unit 4.

  FIG. 16 is a diagram schematically illustrating the time when two charged particle generators 65 respectively generate charged particles in the electric vacuum cleaner 400 of the fourth embodiment. When dust is detected, as shown in FIG. 16, the charged particle generator disposed in the hand operation unit 4 is delayed by time T from the activation of the charged particle generator 65 disposed in the suction port 2. 65 is activated.

  The time T is preset based on the time measured in experiments or the like. The time T is preferably shorter than the time until the detected dust reaches the dust collector 12. The time T is set as, for example, the time until dust that has passed through the position of the detector 7 reaches the hand operating unit 4. The time T may be 0 (zero).

  When dust is not detected, the charged particle generator 65 stops generating charged particles. When the operation of the vacuum cleaner 400 is continued and dust is sucked in again, dust is detected again, the charged particle generator 65 of the suction port body 2 first generates positive ions, and the hand operation unit No. 4 charged particle generator 65 first generates negative ions. In the vacuum cleaner 400 of the fourth embodiment, such an operation of the charged particle generator 65 is repeated until the operation of the vacuum cleaner 400 is stopped.

  As described above, the vacuum cleaner 400 includes the charged particle generator 65 as an example of the first charged particle generator disposed in the suction port 2 and the second charged particles disposed in the hand operation unit 4. A charged particle generator 65 as an example of a generator is provided. The control device 15 is configured such that the charged particle generator 65 disposed in the suction port 2 generates positive ions and negative ions alternately, and the charged particle generator 65 disposed in the suction port 2 generates ions. The charged particle generator 65 of the suction port 2 and the charged particle generation of the hand operating unit 4 so that the charged particle generator 65 arranged in the hand operating unit 4 alternately generates ions having the opposite polarity of The device 65 is controlled.

  According to this configuration, when the charged particle generator 65 of the suction port 2 generates positive ions from the time when dust is detected, the positive ions are not adsorbed to the dust charged to a positive potential. On the other hand, in this case, positive ions are adsorbed to the pipe charged to a negative potential. As a result, the piping is always kept electrically neutral or has a positive potential. Therefore, the dust flows through the pipe while repelling each other, and dust charged to a positive potential is repelled from the pipe while flowing through the pipe. Thus, according to this structure, it can suppress that dust adheres to piping upstream from the position where the charged particle generator 65 of the hand operation part 4 is arrange | positioned.

  On the other hand, when the charged particle generator 65 of the hand operation unit 4 generates negative ions from the time when dust is detected, the dust is further downstream from the position where the charged particle generator 65 of the hand operation unit 4 is disposed. Is sterilized by adsorbing negative ions, and is electrically neutralized or charged to a negative potential. On the other hand, since the pipe is charged to a negative potential downstream of the position where the charged particle generator 65 of the hand operation unit 4 is disposed, the electrically neutralized dust or the dust charged to the negative potential is Repelled by piping. Therefore, it is possible to prevent dust from adhering to the piping even downstream from the position where the charged particle generator 65 of the hand operation unit 4 is disposed.

  Since the charged particle generator 65 of the suction inlet 2 generates positive ions after generating positive ions, the negative ions are adsorbed to dust charged to a positive potential. Dust is sterilized by adsorbing negative ions, and is electrically neutralized or charged to a negative potential. On the other hand, negative ions are not adsorbed to the pipe charged to a negative potential. Moreover, while circulating through the piping, dust charged to a negative potential repels, and dust repels the piping charged to a negative potential. Thus, according to this structure, it can suppress that dust adheres to piping upstream from the position where the charged particle generator 65 of the hand operation part 4 is arrange | positioned.

  On the other hand, since the charged particle generator 65 of the hand operation unit 4 generates negative ions after generating negative ions, the dust passing through the position where the charged particle generator 65 of the hand operation unit 4 is disposed is positive. When ions are adsorbed to dust, they are electrically neutralized or charged to a positive potential. Furthermore, dust is sterilized by the reaction of positive ions and negative ions. Since the pipe is charged at a negative potential downstream from the position where the charged particle generator 65 of the hand operation unit 4 is disposed, the positive ions are electrically neutralized by being adsorbed on the pipe or charged to the positive potential. To do. Therefore, it is possible to suppress the dust from adhering to the piping even downstream from the position where the charged particle generator 65 of the hand operation unit 4 is disposed.

  Thus, positive ions and negative ions are alternately generated in the charged particle generator 65 of the suction port 2, and the polarity is opposite to the polarity of the ions generated by the charged particle generator 65 of the suction port 2. As the ions having the same are repeatedly generated in the charged particle generator 65 of the hand operation unit 4, the dust that has passed through the position where the charged particle generator 65 of the suction port 2 is disposed becomes the hand operation unit 4. After passing through the position where the charged particle generator 65 is disposed, a series of actions of being electrically neutralized and sterilized by ions of opposite polarity are repeated. By doing in this way, the dust collected by the dust collector 12 can be accumulated in the electrically neutralized state and the sterilized state.

  In the cleaning device according to the fourth embodiment, the control device 15 includes the charged particle generator 65 of the suction port body 2 and the hand operation unit so that the timing of generating positive ions and negative ions is switched every predetermined period. 4 charged particle generators 65 are controlled.

  According to this configuration, when a predetermined time elapses, the charged particle generator 65 of the suction port body 2 and the charged particle generator 65 of the hand operation unit 4 switch between generating positive ions and negative ions. be able to. According to this configuration, the charged particle generator 65 of the suction port body 2 sends positive ions into the pipe when dust is detected, and negative ions into the pipe when a predetermined time elapses. By sending out, positive ions and negative ions can be repeatedly sent into the pipe alternately every predetermined period. The charged particle generator 65 of the hand operation unit 4 sends negative ions to the inside of the pipe when dust is detected, and sends positive ions to the inside of the pipe when a predetermined time elapses. The positive ions and the negative ions can be alternately sent to the inside of the pipe every predetermined period. In this way, the dust potential and the piping potential can be effectively neutralized by positive ions and negative ions.

  In the cleaning device according to the fourth embodiment, the charged particle generator 65 of the suction port body 2 is not limited to be operated so as to generate charged particles having a positive potential first. The particle generator 65 may be operated to generate charged particles having a negative potential first. That is, the charged particle generator 65 of the hand operation unit 4 may be operated so as to first generate charged particles having a positive potential. Even if it is such a structure, the effect similar to the effect mentioned above can be acquired.

  The number of charged particle generators 65 is not limited to 2, and may be 3 or more. For example, one or more first charged particle generation units may be disposed in the suction port body 2, and one or more second charged particle generation units may be disposed downstream of the suction port body 2.

  The first charged particle generation unit is not limited to being disposed in the suction port body 2, and may be disposed in the hand operation unit 4, the extension pipe 3, or the hose 5. Further, the second charged particle generation unit is not limited to being arranged in the hand operation unit 4.

  In particular, the position of the second charged particle generation unit may be the suction port 10a of the main body 1, the suction port 12a of the dust collector 12, or the vicinity thereof. However, even when the second charged particle generation unit is disposed at such a position, the period at which the timing for generating the positive charged particles and the timing for generating the negative charged particles are switched as described above. It is preferable that they are set as follows.

(Fifth embodiment)
Below, the cleaning device concerning a 5th embodiment is explained. In the following, the configuration of the vacuum cleaner 100 as an example of the cleaning device according to the first embodiment and the configuration having the same function as the charged particle generator 65 of the cleaning device according to the second, third, and fourth embodiments. Are denoted by the same reference numerals, and the description thereof is omitted.

  As described below, the cleaning device according to the fifth embodiment differs from the cleaning device according to the fourth embodiment in that the control device 15 (see FIG. 12) The two charged particle generators 65 are controlled so that positively charged particles and negatively charged particles are alternately generated according to when dust is detected and when dust is not detected.

  FIG. 17 is a diagram schematically illustrating the timing when two charged particle generators 65 respectively generate charged particles in the cleaning device according to the fifth embodiment. As shown in FIG. 17, the charged particle generator 65 disposed in the hand operation unit 4 is activated with a delay of time T from the activation of the charged particle generator 65 disposed in the suction port 2.

  In the cleaning device according to the fifth embodiment, the charged particle generator 65 disposed in the suction port body 2 generates positive ions from the time when dust is detected. The charged particle generator 65 disposed in the hand operation unit 4 generates negative ions with a delay of time T from the activation of the charged particle generator 65. In addition, when no dust is detected, the charged particle generator 65 disposed in the suction port 2 generates negative ions from the time when the dust is no longer detected by the control device 15. The charged particle generator 65 disposed in the hand operation unit 4 generates positive ions with a delay of time T from the generation of negative ions of the charged particle generator 65 of the suction port 2.

  Thus, in the cleaning device according to the fifth embodiment, the control device 15 causes the charged particle generator 65 of the suction port body 2 to generate positive ions, and the charged particle generator 65 of the hand operation unit 4 is negative. A case in which ions are generated and a case in which the charged particle generator 65 of the suction port body 2 generates negative ions and the charged particle generator 65 of the hand operation unit 4 generates positive ions are distinguished. The charged particle generator 65 is controlled. Specifically, the control device 15 sets the two charged particle generators 65 so that positive ions and negative ions are alternately generated according to the case where dust is detected and the case where dust is not detected. Control.

  The control device 15 causes the charged particle generator 65 of the suction port 2 to generate positive ions so that the charged particle generator 65 of the suction port 2 generates positive ions from the time when dust is sucked. Generates positive ions when dust is detected while the charged particle generator 65 of the suction port 2 is generating negative ions, so that negative ions are generated when dust is no longer detected. The charged particle generation device 65 of the suction port body 2 is controlled so as to make it happen. When the charged particle generator 65 disposed in the suction port 2 generates positive ions, the charged particle generator 65 disposed in the hand operation unit 4 generates negative ions. On the other hand, when the charged particle generator 65 arranged in the suction port 2 generates negative ions, the charged particle generator 65 arranged in the hand operation unit 4 generates negative ions. In the cleaning device according to the fifth embodiment, such operations of the two charged particle generators 65 are repeated until the operation of the cleaning device is stopped.

  As described above, in the cleaning device according to the fifth embodiment, the control device 15 detects positive ions and negative ions depending on whether dust is detected by the control device 15 or when dust is not detected by the control device 15. The charged particle generator 65 of the suction port 2 and the charged particle generator 65 of the hand operation unit 4 are controlled so that ions are alternately generated.

  According to this configuration, the charged particle generating device 65 of the suction port body 2 and the charged particle generating device 65 of the hand operating unit 4 are positive ions according to whether dust is detected or not detected. It can be generated by switching negative ions. According to this configuration, the charged particle generator 65 of the suction inlet 2 sends positive ions into the pipe every time dust is detected, and sends negative ions into the pipe every time no dust is detected. By doing so, positive ions and negative ions can be alternately and repeatedly sent into the pipe. The charged particle generator 65 of the hand operation unit 4 sends negative ions to the inside of the pipe every time dust is detected, and sends positive ions to the inside of the pipe every time dust is no longer detected. Positive ions and negative ions can be alternately and repeatedly sent into the pipe. In this way, the dust potential and the piping potential can be effectively neutralized by positive ions and negative ions.

The charged particle emitting unit 70b of the charged particle generator 70 includes a needle-like discharge electrode 701b and an induction electrode 702b. The charged particle emitting unit 71c of the charged particle generator 71 includes a needle-like discharge electrode 711c and an induction electrode 712c. The induction electrodes 702b and 712c are sheet metals each having a hole. The needle-like discharge electrode 701b is disposed inside the main body 70a so that the straight line passing through the center line of the hole of the induction electrode 702b and the direction in which the tip of the discharge electrode 701b extends substantially coincide. Similarly, the needle-like discharge electrode 711c is disposed inside the main body 71a so that a straight line passing through the center line of the hole of the induction electrode 712c and a direction in which the tip of the discharge electrode 711c extends substantially coincide. .

  In addition, the main body portions 70a and 71a contain circuits that generate high-voltage electricity applied to the discharge electrodes 701b and 711c, respectively. The main body 70a is a housing that houses the discharge electrode 701b, the induction electrode 702b, and these circuits. The main body 71a is a housing that houses the discharge electrode 711c, the induction electrode 712c, and these circuits. 20 and 21 show an example of a circuit of the charged particle generator 70 and an example of a circuit of the charged particle generator 71, respectively. The negative potential charged particle generator 71 has a configuration in which the diode of the charged particle discharge unit 70b in the positive potential charged particle generator 70 is attached in the opposite direction.

  FIG. 22 is a diagram schematically illustrating the time when the charged particle generator 70 and the charged particle generator 71 generate charged particles in the cleaning device according to the sixth embodiment. When dust is detected, as shown in FIG. 22, the charged particle generator disposed in the hand operation unit 4 is delayed by time T from the activation of the charged particle generator 70 disposed in the suction port 2. 71 starts.

  When dust is not detected, the charged particle generator 70 and the charged particle generator 71 stop generating charged particles. When the operation of the cleaning device is continued and dust is sucked in again, dust is detected again, and the charged particle generator 70 of the suction port body 2 generates positive ions again, and charging of the hand operation unit 4 is performed. The particle generator 71 generates negative ions. Such operation of the charged particle generator 70 and the operation of the charged particle generator 71 are repeated until the operation of the cleaning device is stopped.

  According to this configuration, when the charged particle generator 70 generates positive ions from the time when dust is detected, the positive ions are not adsorbed to the dust charged to a positive potential. On the other hand, in this case, the positive ions are adsorbed on the negatively charged pipe, whereby the pipe is electrically neutralized or charged to the positive potential. For this reason, the dust flows through the pipe while repelling each other, and dust charged electrically at a positive potential is repelled from the pipe while flowing through the pipe. Thus, according to this structure, it can suppress that dust adheres to piping upstream from the position where the charged particle generator 71 is arrange | positioned.

It is sterilized and electrically neutralized or charged to a negative potential. On the other hand, since the pipe is charged at a negative potential downstream from the position where the charged particle generator 71 is disposed, the electrically neutralized dust or the negatively charged dust is repelled by the pipe. The Therefore, it is possible to prevent dust from adhering to the piping even downstream of the position where the charged particle generator 71 is disposed.

  In the cleaning device according to the sixth embodiment, the charged particle generator 70 disposed in the suction port 2 generates positive ions, and the charged particle generator 71 disposed in the hand operation unit 4 generates negative ions. Without being limited to the generation, the charged particle generator 71 is disposed in the suction port 2, whereby negative ions are mixed with air in the suction port 2, and the charged particle generator 70 is added to the hand operation unit 4. May be configured so that positive ions are mixed with air inside the hand operation unit 4. Even if it is such a structure, the effect similar to the effect mentioned above can be acquired.
