Description

静電噴霧装置Electrostatic spraying equipment
　　本発明は、静電噴霧装置に関し、特に、噴霧の安定化対策に係るものである。 The present invention relates to an electrostatic spraying apparatus, and particularly relates to measures for stabilizing spraying.
　　従来、液体噴霧装置は、容器内に貯留された液体を噴霧させるように構成されている。この液体噴霧装置には、容器の出口となるノズルに送り込まれた液体を、ノズルの先端から電界強度によって噴霧させる静電噴霧装置が知られている。このような静電噴霧装置を特許文献１に示す。 Conventionally, the liquid spraying device is configured to spray the liquid stored in the container. As this liquid spraying device, an electrostatic spraying device that sprays liquid fed into a nozzle serving as an outlet of a container from the tip of the nozzle by electric field strength is known. Such an electrostatic spraying apparatus is shown in Patent Document 1.
　　特許文献１に示す静電噴霧装置では、一端が蝶番で連結された一対のケースからなるハウジングを備えている。各ケースには、弾性的に変形可能な材料のパッドが設けられている。この静電噴霧装置では、ハウジングを閉じる際に、パッドが液体を貯留する容器である小袋を挟み込みながら収縮する。小袋は、パッドによって圧縮されて小袋内の液体がノズルに供給される。このノズルに電界を形成することでノズルの先端から小袋内の液体を噴霧させる。 The electrostatic spraying device shown in Patent Document 1 includes a housing composed of a pair of cases whose one ends are connected by a hinge. Each case is provided with a pad of an elastically deformable material. In this electrostatic spraying device, when the housing is closed, the pad contracts while sandwiching a small bag that is a container for storing liquid. The pouch is compressed by the pad and the liquid in the pouch is supplied to the nozzle. By forming an electric field at the nozzle, the liquid in the pouch is sprayed from the tip of the nozzle.

　　ところで、上述した静電噴霧装置を室内に設置して、帯電させた溶液によって室内を加湿すると、水分を対象物である人に集中的に供給することができる。この際、帯電電荷は、人側に移動する一方、帯電電荷に対して逆極性の電荷が静電噴霧装置に残ることになる。このような残留電荷が静電噴霧装置に大量に蓄積すると、静電噴霧装置内の帯電電位と人での間の電位差が変化するため、噴霧が妨害される要因となる。したがって、静電噴霧装置には、電荷が残らないよう、電荷を逃がすアースラインを形成する必要がある。 By the way, when the above-described electrostatic spraying apparatus is installed in a room and the room is humidified by a charged solution, moisture can be intensively supplied to the person who is the object. At this time, the charged charges move to the human side, while charges having a polarity opposite to the charged charges remain in the electrostatic spraying device. When such a residual charge is accumulated in a large amount in the electrostatic spraying device, the potential difference between the charged potential in the electrostatic spraying device and the person changes, which is a factor that hinders spraying. Therefore, it is necessary to form an earth line in the electrostatic spraying device for releasing charges so that no charges remain.
　　しかしながら、図３に示すように、静電噴霧装置（a）を室内に設置する場合、静電噴霧装置（a）に対して家庭用の交流電源（b）からＡＣアダプタ（c）を介して電源供給することが考えられる。この際に、ＡＣアダプタ（c）を構成する電子部品に絶縁トランスが用いられていると、静電噴霧装置（a）内に残った電荷が絶縁トランスを通過することができない。このため、静電噴霧装置（a）に残った電荷をアースに流すことができず、静電噴霧装置（a）内に電荷が蓄積するという問題があった。 However, as shown in FIG. 3, when the electrostatic spraying device (a) is installed indoors, the household AC power source (b) is connected to the electrostatic spraying device (a) via the AC adapter (c). It is conceivable to supply power. At this time, if an insulating transformer is used for the electronic components constituting the AC adapter (c), the charge remaining in the electrostatic spraying device (a) cannot pass through the insulating transformer. For this reason, the electric charge remaining in the electrostatic spraying device (a) cannot flow to the ground, and there is a problem that the electric charge accumulates in the electrostatic spraying device (a).
　　本発明は、斯かる点に鑑みてなされたものであり、静電噴霧装置内に残留電荷が蓄積するのを防止することを目的とする。 The present invention has been made in view of such a point, and an object thereof is to prevent residual charges from accumulating in an electrostatic spraying device.
　　第１の発明は、入力された交流を直流に変換する直流変換回路（20）を備え、該直流変換回路（20）から出力された出力電圧を利用して帯電させた溶液を対象物（Ｐ）に向かって霧化状態で噴霧する静電噴霧装置を対象としている。上記直流変換回路（20）は、上記入力された交流電圧を変圧する絶縁変圧器（23）と、該絶縁変圧器（23）で変圧された交流を整流する整流器（24）とを有し、上記直流変換回路（20）は、上記絶縁変圧器（23）の１次側のアースと、該絶縁変圧器（23）の２次側のアースライン（27b）とを繋いで上記絶縁変圧器（23）を迂回するバイパス回路（30）とを備えている。 The first invention includes a direct current conversion circuit (20) for converting input alternating current into direct current, and a solution charged using the output voltage output from the direct current conversion circuit (20) is an object (P ) Toward an electrostatic spraying device that sprays in an atomized state. The DC conversion circuit (20) includes an insulation transformer (23) that transforms the input AC voltage, and a rectifier (24) that rectifies the alternating current transformed by the insulation transformer (23). The DC converter circuit (20) connects the ground on the primary side of the insulation transformer (23) and the ground line (27b) on the secondary side of the insulation transformer (23) to connect the insulation transformer ( 23) and a bypass circuit (30) for bypassing.
　　上記第１の発明では、直流変換回路（20）が交流を直流に変換する。そして、変換した直流を利用して溶液を帯電する。そして、帯電させた溶液を噴霧の対象物（Ｐ）である人に向かって噴霧する。このとき、噴霧した溶液と共に帯電電荷が対象物（Ｐ）である人側に移動する。人側に移動した帯電電荷は、対象物（Ｐ）である人体を介してアースに流れる。その一方、静電噴霧装置側では、上記帯電電荷に対して逆極性の電荷が残留する。この残留した電荷は、バイパス回路（30）を通ることで絶縁変圧器を迂回してアースに流れる。 In the first invention, the DC conversion circuit (20) converts AC to DC. Then, the solution is charged using the converted direct current. Then, the charged solution is sprayed toward the person to be sprayed (P). At this time, the charged electric charge moves together with the sprayed solution toward the person who is the object (P). The charged charge that has moved to the human side flows to the ground via the human body that is the object (P). On the other hand, on the electrostatic spraying device side, a charge having a polarity opposite to the charged charge remains. This remaining charge flows through the bypass circuit (30) to the ground, bypassing the isolation transformer.
　　第２の発明は、上記第１の発明において、上記直流変換回路（20）は、上記絶縁変圧器（23）の１次側に交流が入力される一対の入力ライン（28，28）が形成されて構成され、上記バイパス回路（30）は、上記一の入力ライン（28）と、上記絶縁変圧器（23）の２次側のアースライン（27b）とを繋いで上記絶縁変圧器（23）を迂回する第１回路（30a）と、上記他の入力ライン（28）と、上記絶縁変圧器（23）の２次側のアースライン（27b）とを繋いで上記絶縁変圧器（23）を迂回する第２回路（30b）とを備え、上記第１および第２回路（30a，30b）は、高抵抗の電気抵抗部材（32）がそれぞれ設けられている。 In a second aspect based on the first aspect, the direct current conversion circuit (20) includes a pair of input lines (28, 28) through which alternating current is input to the primary side of the isolation transformer (23). The bypass circuit (30) is configured to connect the one input line (28) to the secondary ground line (27b) of the isolation transformer (23) to connect the isolation transformer (23 ), The first input circuit (30a), the other input line (28), and the secondary earth line (27b) of the insulation transformer (23) to connect the insulation transformer (23). The first circuit and the second circuit (30a, 30b) are each provided with a high resistance electric resistance member (32).
　　上記第２の発明では、静電噴霧装置に残留した電荷は、電気抵抗部材（32）が設けられたバイパス回路（30）を通過する。この際に、第１回路（30a）および第２回路（30b）のどちらかが、アースに繋がる入力ライン（28）に接続される。したがって、上記残留電荷は、第１回路（30a）または第２回路（30b）を通過してアースに流れる。一方、入力ライン（28，28）から入力された交流電流は、第１回路（30a）および第２回路（30b）のそれぞれに設けられた電気抵抗部材（32）によって、該電気抵抗部材（32）の２次側に流れない。 In the second invention, the electric charge remaining in the electrostatic spraying device passes through the bypass circuit (30) provided with the electric resistance member (32). At this time, either the first circuit (30a) or the second circuit (30b) is connected to the input line (28) connected to the ground. Accordingly, the residual charge flows to the ground through the first circuit (30a) or the second circuit (30b). On the other hand, the alternating current input from the input lines (28, 28) is supplied to the electric resistance member (32) by the electric resistance member (32) provided in each of the first circuit (30a) and the second circuit (30b). ) Does not flow to the secondary side.
　　上記第１の発明によれば、絶縁変圧器（23）を迂回するバイパス回路（30）を設けたため、アースラインを形成することができる。したがって、静電噴霧装置に残った電荷は絶縁変圧器（23）を迂回してアースに流れることになる。これにより、静電噴霧装置に残留した電荷が蓄積するのを確実に防止することができる。 According to the first aspect of the invention, since the bypass circuit (30) that bypasses the insulation transformer (23) is provided, an earth line can be formed. Therefore, the electric charge remaining in the electrostatic spraying device bypasses the insulation transformer (23) and flows to the ground. Thereby, it can prevent reliably that the electric charge which remained in the electrostatic spraying apparatus accumulate | stores.
　　上記第２の発明によれば、第１回路（30a）および第２回路（30b）に、高抵抗の電気抵抗部材（32）をそれぞれ設けたため、交流電流が２次側に流れることを防止することができるので、１次側と２次側との短絡を確実に防止することができる。これにより、静電噴霧装置に残留した電荷が蓄積するのを確実に防止することができる。 According to the second aspect of the present invention, since the high resistance electric resistance member (32) is provided in each of the first circuit (30a) and the second circuit (30b), the alternating current is prevented from flowing to the secondary side. Therefore, it is possible to reliably prevent a short circuit between the primary side and the secondary side. Thereby, it can prevent reliably that the electric charge which remained in the electrostatic spraying apparatus accumulate | stores.
　　また、一対の入力ライン（28，28）のぞれぞれに対応する第１回路（30a）および第２回路（30b）を設けたため、２本の入力ライン（28，28）のどちらにアースが繋がれても、静電噴霧装置に残留した電荷は絶縁変圧器（23）を迂回させてアースに流すことができる。これにより、静電噴霧装置に残った電荷が蓄積するのを確実に防止することができる。 In addition, since the first circuit (30a) and the second circuit (30b) corresponding to each of the pair of input lines (28, 28) are provided, either of the two input lines (28, 28) is grounded. Even if they are connected, the electric charge remaining in the electrostatic spraying device can flow to the ground by bypassing the insulation transformer (23). Thereby, it can prevent reliably that the electric charge which remained in the electrostatic spraying apparatus accumulate | stores.

　　　　－運転動作－
　　次に本実施形態の運転動作について説明する。本実施形態の静電噴霧装置（10）を使用する際は、まず、電源スイッチをＯＮにする（図示なし）。これにより、ＡＣアダプタ（20）から供給された直流電圧は、電圧印加機構（16）によってタンク（13）内の噴霧溶液に印加される。このとき、上記タンク（13）内の噴霧溶液は、液供給機構（15）によって単位時間当たりにわずかな量ずつ送り出されて噴霧ノズル（14）の先端に移動する。ここで、電圧が印加されたタンク（13）内の噴霧溶液は、液体が分極し、噴霧ノズル（14）の先端の気液界面の近傍に例えば＋（プラス）の電荷が集まる。そして、噴霧ノズル（14）の先端のでは、気液界面が引き延ばされて円錐状となり、この円錐状となった気液界面の頂部から一部の水溶液が引きちぎられて液滴化する。この作用が繰り返し発生して、噴霧ノズル（14）から噴霧溶液の液滴が人体（Ｐ）に向かって噴霧される。 -Driving operation-
Next, the driving operation of this embodiment will be described. When using the electrostatic spraying device (10) of this embodiment, first, the power switch is turned on (not shown). Thereby, the DC voltage supplied from the AC adapter (20) is applied to the spray solution in the tank (13) by the voltage application mechanism (16). At this time, the spray solution in the tank (13) is sent out by a small amount per unit time by the liquid supply mechanism (15) and moves to the tip of the spray nozzle (14). Here, in the spray solution in the tank (13) to which the voltage is applied, the liquid is polarized and, for example, + (plus) charges are collected in the vicinity of the gas-liquid interface at the tip of the spray nozzle (14). Then, at the tip of the spray nozzle (14), the gas-liquid interface is extended into a conical shape, and a part of the aqueous solution is torn off from the top of the conical gas-liquid interface to form droplets. This action occurs repeatedly, and droplets of the spray solution are sprayed from the spray nozzle (14) toward the human body (P).
　　ここで、噴霧された噴霧溶液と共に帯電電荷が人体（Ｐ）側に移動する。人体に移動した帯電電荷は人体（Ｐ）を介してアースに流れる。その一方、静電噴霧装置（10）側では、タンク（13）内に帯電電荷に対して逆極性の電荷（例えば－（マイナス）の電荷）が残留する。この残留電荷は、第１配線（30a）または第２配線（30b）を通ることで絶縁トランス（23）を迂回する。そして、２本の入力配線（28，28）のうち、交流電源（2）のアースと接続される入力配線（28）を介してアースに流れる。 Here, the charged charge moves to the human body (P) side together with the spray solution sprayed. The charged charge that has moved to the human body flows to the ground via the human body (P). On the other hand, on the electrostatic spraying device (10) side, a charge (for example, a negative charge) having a polarity opposite to the charged charge remains in the tank (13). This residual charge bypasses the insulating transformer (23) by passing through the first wiring (30a) or the second wiring (30b). Of the two input wirings (28, 28), the current flows to the ground through the input wiring (28) connected to the ground of the AC power supply (2).
　　　　－実施形態の効果－
　　本実施形態によれば、絶縁トランス（23）を迂回するバイパス回路（30）を設けたため、アースラインを形成することができる。したがって、静電噴霧装置本体（10a）に残った電荷は、絶縁トランス（23）を迂回してアースに流れることになる。また、第１配線（30a）および第２配線（30b）に、高抵抗の抵抗器（32）をそれぞれ設けたため、交流電流が２次側に流れることを確実に防止することができるので、１次側と２次側との短絡を確実に防止することができる。これらにより、静電噴霧装置本体（10a）に残留した電荷が蓄積するのを確実に防止することができる。 -Effects of the embodiment-
According to this embodiment, since the bypass circuit (30) that bypasses the insulating transformer (23) is provided, an earth line can be formed. Accordingly, the charge remaining in the electrostatic spraying device main body (10a) flows to the ground bypassing the insulating transformer (23). In addition, since the high-resistance resistors (32) are respectively provided in the first wiring (30a) and the second wiring (30b), it is possible to reliably prevent the alternating current from flowing to the secondary side. A short circuit between the secondary side and the secondary side can be reliably prevented. By these, it can prevent reliably that the electric charge which remained in the electrostatic spraying apparatus main body (10a) accumulates.
　　また、２本の入力配線（28，28）に対応して第１配線（30a）および第２配線（30b）を設けたため、使用者が、差込プラグ（22）を交流電源（2）（家庭用のコンセント）のどちらの向きに差し込んでも、第１配線（30a）または第２配線（30b）のどちらか一方を確実に交流電源（2）のアースに繋げることができる。これにより、静電噴霧装置本体（10a）の残留電荷を確実にアースに流すことができる。 Further, since the first wiring (30a) and the second wiring (30b) are provided corresponding to the two input wirings (28, 28), the user connects the plug (22) to the AC power source (2) ( Regardless of the orientation of the household electrical outlet, either the first wiring (30a) or the second wiring (30b) can be reliably connected to the ground of the AC power source (2). Thereby, the residual charge of the electrostatic spraying device main body (10a) can be surely flowed to the ground.
