【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、電動工具接続用のコンセントを内装する単相100Vの電源で使用 される携帯用集じん機に関するものである。 The present invention relates to a portable dust collector used with a single-phase 100V power source, which is equipped with an outlet for connecting an electric tool.

【0002】[0002]

【従来の技術】[Prior art]

従来の携帯用集じん機(掃除機)について、図3乃至図5を用いて説明する。 電動工具21より発生する切削粉じんを集じんする集じん機は、電動工具の作業 性向上を目的に、集じん機本体ケース部22に電動工具の電源コード23を接続 する電動工具用コンセント24が内装されている。この電動工具用コンセントは 集じん機に内装された電動機用の電源コード25に図4に示す如く配線され、1 本の電源コード25及び1個の電源プラグ26で建屋の壁等に設置された屋内配 線コンセント27から電力を供給されていた。 A conventional portable dust collector (vacuum cleaner) will be described with reference to FIGS. 3 to 5. The dust collector that collects the cutting dust generated by the power tool 21 has a power tool outlet 24 that connects the power cord 23 of the power tool to the dust collector body case 22 in order to improve the workability of the power tool. It is decorated. This power tool outlet is wired to the electric power cord 25 for the electric motor installed in the dust collector as shown in FIG. 4, and is installed on the wall of the building with one power cord 25 and one power plug 26. Power was supplied from the indoor wiring outlet 27.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来の携帯用集じん機では、図4の配線図に示されるとおり、集じんファンを 駆動する電動機28と電動工具用コンセント24が、1系統の共用電源コード2 5と電源プラグ26により電力が供給されていたため、下記の問題点を有してい た。 In the conventional portable dust collector, as shown in the wiring diagram of FIG. 4, the electric power for driving the dust collecting fan 28 and the power tool outlet 24 are supplied by the common power cord 25 of one system and the power plug 26. Since it was supplied, it had the following problems.

【0004】 (1)電動工具は一般に、定格電流が4〜14A(アンペア)までの機種がある 。但し、一般には4〜11Aまでの機種が主力製品となっていて、11Aを超え る機種は少ない。これにより定格電流11Aまでの電動工具を電動工具用コンセ ントに接続し顧客に使用してもらうと電気用品取締法の技術基準より、屋内配線 コンセント及び電源プラグに流せる電流は平型の2極差し込み式で1ケ所当り1 5A以下のため、集じんファンを駆動する電動機の定格電流は15A−11A= 4Aとなる。電動工具によりコンクリート等被削材を加工する際に発生する粉じ んを集じんするには、定格電流4Aの集じん機でも十分な能力があるが、作業現 場の掃除など、掃除機としてこの集じん機を使用するには、定格電流4Aの集じ ん機では能力不足で、ほとんど使い物にならないという問題があった。(1) In general, there are models of electric power tools having a rated current of 4 to 14 A (ampere). However, in general, models of 4 to 11A are the main products, and few models exceed 11A. As a result, when a power tool with a rated current of up to 11A is connected to a power tool container and used by the customer, the current that can be sent to the indoor wiring outlet and power plug is a flat type 2-pole plug according to the technical standards of the Electrical Appliance and Material Control Law. Since 15A or less per location in the formula, the rated current of the electric motor driving the dust collecting fan is 15A-11A = 4A. A dust collector with a rated current of 4A is sufficient for collecting dust generated when machining a work material such as concrete with an electric tool, but it can be used as a vacuum cleaner for cleaning the work site. In order to use this dust collector, there was a problem that the dust collector with a rated current of 4A was insufficient in its performance and was almost useless.

【0005】 (2)掃除機としての能力を十分に持たせるためには、集じんファンを駆動する 電動機の定格電流は10A程度必要となる。このため、電動工具用コンセントに は、電動工具の定格電流が5A以下の電動工具しか接続できないため、ほとんど の電動工具を接続することができないという問題があった。(2) The rated current of the electric motor for driving the dust collecting fan is required to be about 10 A in order to have sufficient ability as a cleaner. For this reason, there is a problem in that most power tools cannot be connected to the power tool outlet because only power tools having a rated current of 5 A or less can be connected to the power tool outlet.

【0006】 本考案の目的は、上記した問題点を解消するため、集じん作業の用途に合わせ て集じん能力を切り替えることにある。An object of the present invention is to switch the dust collecting ability according to the use of dust collecting work in order to solve the above-mentioned problems.

【0007】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的は、電動工具用コンセントに電流を流す場合のみ、集じんファンを駆 動する電動機に流れる電流を制御する回路を搭載することにより達成される。 The above object is achieved by mounting a circuit for controlling the current flowing through the electric motor that drives the dust collecting fan only when the electric current is supplied to the outlet for the electric power tool.

【0008】[0008]

【作用】[Action]

上記のように構成された携帯用集じん機は、電動工具用コンセントに電流が流 れたことを検出する回路により電流が検出されると、集じんファンを駆動する電 動機に接続された電流制御回路を動作させ、電動機に流れる電流を減少させるよ うに動作する。 With the portable dust collector configured as described above, when the current is detected by the circuit that detects the current flowing in the outlet for the electric power tool, the current connected to the dust collector driving the dust collecting fan is detected. Operates the control circuit to reduce the current flowing to the motor.

【実施例】【Example】

本考案になる携帯用集じん機の一実施例を図1及び図2を用いて説明する。本 体ケース1には電源プラグ2付の電源コード3が組込まれ、内部には電動機4、 および集じんファン(図示せず)が内装され、本体ケース1の前面には、電動機 4をON−OFFする運転スイッチ5及び電動工具6の電源コード7を接続する ための電動工具用コンセント8が装着されている。電動工具用コンセントと電動 機は、1系統の共用電源コード及び電源プラグから電力を供給され、電動機は運 転スイッチによりON−OFFされる。ダストケース9の内部には、粉じんをろ 過するフィルター(図示せず)が内装されており、ダクトホーク10から集じん された粉じんは、フィルターでろ過され、ダストケース9の内部に収納される。 An embodiment of the portable dust collector according to the present invention will be described with reference to FIGS. 1 and 2. A power cord 3 with a power plug 2 is incorporated in the main body case 1, an electric motor 4 and a dust collecting fan (not shown) are internally provided, and the electric motor 4 is turned on in the front surface of the main body case 1. A power tool outlet 8 for connecting the power switch 7 of the power switch 6 and the operation switch 5 that is turned off is mounted. Electric power is supplied to the electric tool outlet and the electric motor from the common power cord and power plug of one system, and the electric motor is turned on and off by the operation switch. A filter (not shown) for filtering dust is installed inside the dust case 9, and the dust collected from the duct hawk 10 is filtered by the filter and stored inside the dust case 9. .

【0010】 以上のように構成された携帯用集じん機において、電流検出回路11を電動工 具用コンセント8と直列に設け、集じんファンを駆動する電動機に流れる電流を 可変させる電流制御部12を電動機と直列に設ける。電流検出回路11は、電動 工具用コンセント8に流れる電流を検出し、検出電流の大きさを判断する比較部 13を介して前記電流制御部12に信号を送る。この電流制御部12は信号を受 けると、電動機4に流れる電流を制御する。これにより、電動工具用コンセント 8に電流が流れる時のみ、集じんファンを駆動する電動機の電流を実用上支障な い範囲の電流値に減少させることができる。In the portable dust collector configured as described above, the current detection circuit 11 is provided in series with the electric tool outlet 8 and the current control unit 12 that varies the current flowing through the electric motor that drives the dust collection fan. Is installed in series with the electric motor. The current detection circuit 11 detects a current flowing through the power tool outlet 8 and sends a signal to the current control unit 12 via a comparison unit 13 that determines the magnitude of the detected current. When the current controller 12 receives the signal, it controls the current flowing through the electric motor 4. As a result, the electric current of the electric motor for driving the dust collecting fan can be reduced to a current value within a practically unimpeded range only when the electric current flows through the power tool outlet 8.

【0011】[0011]

【考案の効果】[Effect of device]

本考案によれば、電動工具用コンセントに流れる電流を検出し、集じんファン を駆動する電動機の電流を制御するようにしたので、電動工具を接続しないで作 業現場の掃除を行う時には定格電流の大きい通常の掃除機として使用することが できる。また、電動工具を接続して集じんする時は実用上支障ない電流値まで集 じん機の電流を下げることにより、使用できる電動工具の種類を多くすることが できる。 According to the present invention, the current flowing through the outlet for the electric power tool is detected and the electric current of the electric motor that drives the dust collecting fan is controlled. It can be used as a large vacuum cleaner. Also, when connecting and collecting dust with an electric power tool, it is possible to increase the types of power tools that can be used by reducing the current of the dust collector to a current value that does not hinder practical use.
