Description

本発明は、空気を噴射することにより塵埃を吹き飛ばす空気噴射装置及びそれを用いた電気掃除機に関するものである。   The present invention relates to an air injection device that blows off dust by injecting air, and a vacuum cleaner using the same.

塵埃を吹き飛ばす機能(以下、ブロアー機能と称す)を備えた従来の技術の代表例として、電気掃除機の排気をブロアーに利用した形態が挙げられる。以下、図5から7を用いて、従来の電気掃除機について述べる。   A typical example of a conventional technique having a function of blowing dust (hereinafter referred to as a blower function) includes a form in which the exhaust of a vacuum cleaner is used as a blower. Hereinafter, a conventional vacuum cleaner will be described with reference to FIGS.

図5は、従来のブロアー機能を備えた電気掃除機の全体斜視図、図6は、同電気掃除機の通常使用時の横断面図、図7は、同電気掃除機のブロアー機能使用時の横断面図である。
図5において、従来の電気掃除機の電気掃除機本体50は、電動送風機57と、集塵室58を内蔵している。51は、接続口で、集塵室58に連通すると共に、ホース53の一端に配した接続パイプ52が接続される。吸込口体56は、ホース53の他端に配した手元操作部54もしくは延長管55を介して集塵室58と連通接続される。
FIG. 5 is an overall perspective view of a conventional vacuum cleaner having a blower function, FIG. 6 is a cross-sectional view of the vacuum cleaner during normal use, and FIG. 7 is a diagram of the vacuum cleaner when the blower function is used. It is a cross-sectional view.
In FIG. 5, a vacuum cleaner body 50 of a conventional vacuum cleaner includes an electric blower 57 and a dust collection chamber 58. A connection port 51 communicates with the dust collection chamber 58 and is connected to a connection pipe 52 disposed at one end of the hose 53. The suction port body 56 is connected to the dust collection chamber 58 through a hand operating part 54 or an extension pipe 55 disposed at the other end of the hose 53.

図6、7において、50は、電気掃除機本体で、接続口51は、ホース53の一端に配した接続パイプ52を介してホース53を連通接続できる構成となっている。59は、電動送風機支持壁であり、上下2分割構成をとることで電動送風機57の後端を軟質ゴム60を介して挟持する。61は、電動送風機57から排出される気流62を電気掃除機本体50の外部へ排出する排気口であり、電動送風機57と排気口61を連通する排気通路63は、電動送風機支持壁59と隔離壁64とで閉ざされた空間を形成する。   In FIGS. 6 and 7, reference numeral 50 denotes a main body of the vacuum cleaner, and the connection port 51 is configured to be able to connect the hose 53 through a connection pipe 52 disposed at one end of the hose 53. Reference numeral 59 denotes an electric blower support wall, which sandwiches the rear end of the electric blower 57 via the soft rubber 60 by taking a vertically divided structure. 61 is an exhaust port for discharging the airflow 62 discharged from the electric blower 57 to the outside of the electric vacuum cleaner main body 50, and the exhaust passage 63 communicating the electric blower 57 and the exhaust port 61 is isolated from the electric blower support wall 59. A closed space is formed with the wall 64.

さらに、65は、回動軸66により開閉自在な開閉蓋体であり、開閉蓋体65の凸部67は、接続パイプ52を連通接続できる構成となっている連結口68にはまり込む構成をとると共に、接続パイプ52を連通接続した際には、電動送風機支持壁59と当接し排気通路63を遮断する構成をとっている。   Furthermore, 65 is an open / close lid that can be opened and closed by a rotating shaft 66, and the convex portion 67 of the open / close lid 65 is configured to fit into a connection port 68 that can be connected to the connection pipe 52 in communication. At the same time, when the connection pipe 52 is connected in communication, the exhaust pipe 63 is blocked by contacting the electric blower support wall 59.

上記構成において、図6に示すように、通常使用時には、接続口51から吸引された気流62は、電動送風機57から排気通路63を経て排気口61から排出される。なお、この時、開閉蓋体65は閉じた状態にあり、開閉蓋体65の凸部67が連結口68にはまり込むことで外部からの空気の流入を防止している。   In the above configuration, as shown in FIG. 6, during normal use, the air flow 62 sucked from the connection port 51 is discharged from the exhaust port 61 through the exhaust passage 63 from the electric blower 57. At this time, the opening / closing lid body 65 is in a closed state, and the convex portion 67 of the opening / closing lid body 65 is fitted into the connection port 68 to prevent inflow of air from the outside.

一方、図7に示すように、ブロアー使用時に、接続パイプ52を連結口68に連通接続すれば、開閉蓋体65が回動し電動送風機支持壁59と当接する位置で停止することで排気通路63を遮断するため、接続口51から吸引された気流62は、電動送風機57から排気通路63の途中まで経て連結口68さらにはホース53や延長管55を経て、外部へ噴射される。   On the other hand, as shown in FIG. 7, if the connection pipe 52 is connected to the connection port 68 when the blower is used, the opening / closing lid 65 rotates and stops at a position where it comes into contact with the electric blower support wall 59. In order to shut off 63, the airflow 62 sucked from the connection port 51 is jetted to the outside through the connection port 68, the hose 53, and the extension pipe 55 from the electric blower 57 to the middle of the exhaust passage 63.

また、特許文献1に開示されているように、ホース53は通常使用のように掃除機本体50に接続して、ホース53の他端にある手元操作部54の先あるいは延長管55に接続して吸気を利用して吸引ファン(図示せず)を回転させ、その動力で噴射ファン(図示せず)をまわすことで、別の空気取り入れ口(図示せず)から吸入した空気を噴射させるものも提案されている。   Further, as disclosed in Patent Document 1, the hose 53 is connected to the cleaner body 50 as in normal use, and is connected to the end of the hand operating portion 54 at the other end of the hose 53 or the extension pipe 55. Rotating a suction fan (not shown) using intake air and rotating the injection fan (not shown) with its power to inject air sucked from another air intake (not shown) Has also been proposed.

しかしながら、上記従来の電気掃除機の排気をブロアーに利用した形態では、実際はクリーンな排気であっても、塵埃を吸引した排気を利用するという面で、不衛生なイメージを抱かれたり、上記従来例のように、塵埃の吸引に使用しているホースや延長管等を利用する形態の物では、吸引経路に付着した微量な塵埃が噴出する恐れがあるなど、衛生面で懸念されて利用機会が減り、近年はこの形態でのブロアー機能付の電気掃除機は少なくなっている。   However, in the form in which the exhaust of the conventional vacuum cleaner is used for the blower, even if it is actually clean exhaust, an unsanitary image may be held in terms of using exhaust that sucks dust. As shown in the example, in the case of using a hose or extension pipe used for dust suction, there is a possibility that a small amount of dust attached to the suction path may be ejected. In recent years, there are fewer vacuum cleaners with a blower function in this form.

また、単にブロアーするだけでは、塵が舞い散ってしまい、近年の気密性の高い住宅状況では、単に塵を拡散するだけで、かえって使いづらい機能ともなっている。   In addition, dust blows away simply by blowing, and in the recent highly airtight housing situation, it simply becomes a function that is difficult to use by simply diffusing the dust.

一方、吸引だけでは、負圧が掃除対象に作用するまで、吸込口(以下「ノズル」という)を近接させる必要があり、近接させると、掃除対象が吸い付いついて破損したり、傾いたり、吸込んでしまったりする事があり、掃除し難いケースも存在する。   On the other hand, with suction alone, the suction port (hereinafter referred to as “nozzle”) needs to be close until negative pressure is applied to the object to be cleaned. There are cases where it is difficult to clean.

例えば、造花などの吸引では壊れてしまう置物、ノズルで直接触ると傾いてしまう壁掛けの額や時計、ノズルが届き辛い照明の傘や天井などの高所、家具間や壁との隙間、直接電気掃除機の汚れたノズルを触れさせたくない、手で触る物(電話やFAX)などである。   For example, figurines that are broken by suction such as artificial flowers, wall-mounted foreheads and clocks that tilt when they come into direct contact with nozzles, high places such as umbrellas and ceilings that are difficult to reach with nozzles, gaps between furniture and walls, direct electricity They do not want to touch the dirty nozzle of the vacuum cleaner, or touch it with a hand (phone or fax).

これらの場所では、ブロアー機能が有効であり、さらに、その舞い上がる塵埃をすぐ吸引できるものが望ましい。また、このブロアー機能を欲する場面は、ノズルを近接させにくく、また目視し辛い状況であることが多々あることが考えられる。   In these places, it is desirable that the blower function is effective and that the dust that rises can be sucked immediately. Moreover, it is conceivable that the scene where the blower function is desired is often in a situation where it is difficult to bring the nozzle close to each other and it is difficult to visually observe the nozzle.

本発明は、以上のような従来の課題を解決しようとするものであって、電気掃除機等の吸引発生装置の形態に左右されず、衛生的なブロアー機能とブロアーで吹き飛ばした塵を回収することが出来、さらに塵埃の吸引状況が把握しやすい使い勝手のよい空気噴射装置及びそれを用いた電気掃除機を提供することを目的としている。   The present invention is intended to solve the above-described conventional problems, and is independent of the form of a suction generator such as a vacuum cleaner, and collects dust blown off by a sanitary blower function and blower. It is another object of the present invention to provide a user-friendly air jet apparatus that can easily grasp the dust suction state and a vacuum cleaner using the air jet apparatus.

上記従来の課題を解決するため、本発明の吸引発生装置は、吸引力が作用する吸引室と、空気を噴射する噴射口と連通する噴射室と、前記吸引室に配され吸引力により動作する吸引ファンと、前記噴射室に配され噴射力を発生する噴射ファンと、前記吸引ファンの動力を前記噴射ファンへ伝達する動力伝達手段と、前記動力伝達手段に連結された発電手段を有し、前記吸引室に連通する吸引口を前記噴射口の近傍の後方に設けるとともに、前記発電手段を電源とする塵埃検出手段を設けて、前記吸引口から吸引された塵埃を前記塵埃検出手段で検出して報知するもので、掃除しにくく被掃除面の状況が見づらい場所でも、塵埃検出手段の検出結果を報知してくれるため、塵埃の回収状況が簡単に把握でき、効率よく掃除できる。   In order to solve the above-described conventional problems, a suction generator according to the present invention operates by a suction force that is provided in a suction chamber in which a suction force acts, an injection chamber that communicates with an injection port that injects air, and the suction chamber. A suction fan, an injection fan disposed in the injection chamber and generating an injection force, power transmission means for transmitting the power of the suction fan to the injection fan, and power generation means connected to the power transmission means, A suction port communicating with the suction chamber is provided in the rear of the vicinity of the ejection port, and dust detection means using the power generation means as a power source is provided, and dust sucked from the suction port is detected by the dust detection means. Even if it is difficult to clean and it is difficult to see the condition of the surface to be cleaned, the detection result of the dust detection means is notified so that the dust collection status can be easily grasped and the cleaning can be performed efficiently.

また、本発明の電気掃除機は、塵埃吸引用の電動送風機と、塵埃を捕集する集塵室と、請求項1〜3のいずれか1項に記載の空気噴射装置と、前記空気噴射装置が着脱自在に装着されるホースとを備えたもので、通常の掃除を行いながら、必要な際に空気噴射装置を装着して衛生的にブロアー掃除ができる、便利な電気掃除機を提供できる。   Moreover, the electric vacuum cleaner of this invention is the electric blower for dust suction, the dust collection chamber which collects dust, the air injection apparatus of any one of Claims 1-3, and the said air injection apparatus. It is provided with a hose that is detachably mounted, and can provide a convenient vacuum cleaner that can be cleaned hygienically by installing an air jet device when necessary while performing normal cleaning.

本発明の空気噴射装置及びそれを用いた電気掃除機は、吸引室に吸引力が作用することで噴射口から空気を噴射するもので、電気掃除機等の吸引発生装置の形態に左右されず、衛生的なブロアー機能とブロアーで吹き飛ばした塵を回収することが出来、また、塵埃の吸引状況が視覚的に分かりやすく、掃除しにくい場所でも掃除状況を把握しながら簡単に効率よく掃除できる、使い勝手のよいものである。   The air injection device of the present invention and the electric vacuum cleaner using the air injection device inject air from the injection port by the suction force acting on the suction chamber, and are not affected by the form of the suction generator such as the electric vacuum cleaner. The hygienic blower function and the dust blown off by the blower can be collected, and the dust suction status is visually easy to understand. It is easy to use.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の
形態によって本発明が限定されるものではない。
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(実施の形態1)
図1は、本発明の実施の形態1における空気噴射装置1の内部構成を略断面図で示したものである。
(Embodiment 1)
FIG. 1 is a schematic cross-sectional view showing an internal configuration of an air injection device 1 according to Embodiment 1 of the present invention.

図1において、1は、本実施の形態における空気噴射装置で、吸引口2を有し垂直方向に90度回転可能の吸引管3と排出口4とを連通し、内部に吸引ファン5を装備した吸引室6と、噴射口7を有し垂直方向に90度回転可能な噴射管8と第2の吸引口9を連通し、内部に噴射ファン10を装備した噴射室11と、吸引室6の底面に、噴射室11と回転自在に連結保持した連結部12と、連結部12に固定された軸受13と、軸受13で回転自在に保持されると共に、両端に吸引ファン5と噴出ファン10を保持した動力伝達手段である回転軸14を備えている。   In FIG. 1, reference numeral 1 denotes an air injection device according to the present embodiment, which connects a suction pipe 3 having a suction port 2 and rotatable 90 degrees vertically and a discharge port 4, and is equipped with a suction fan 5 inside. The suction chamber 6, the injection tube 8 having the injection port 7 and rotatable 90 degrees in the vertical direction, and the second suction port 9 communicating with each other, the injection chamber 11 equipped with the injection fan 10 inside, and the suction chamber 6 , A connecting portion 12 rotatably connected to the injection chamber 11, a bearing 13 fixed to the connecting portion 12, and rotatably supported by the bearing 13, and a suction fan 5 and an ejection fan 10 at both ends. The rotating shaft 14 which is the power transmission means which hold | maintained is provided.

また、吸引ファン5と噴出ファン10は、シロッコ形のファンで形成し、排出口4は、吸引室6上の吸引ファン5の回転中心部に、第2の吸引口9は、噴射室11上の噴射ファン10の回転中心部に、それぞれ連結部12とは反対側の面に開口して配されている。ここで、吸引口2を具した吸引管3は、噴射口7を具した噴射管8より短くしており、同方向に揃えた場合に、噴射口7の後方に吸引口2が位置するようになっている。   The suction fan 5 and the blower fan 10 are formed of a sirocco fan, the discharge port 4 is at the rotation center of the suction fan 5 on the suction chamber 6, and the second suction port 9 is on the injection chamber 11. In the center of rotation of the injection fan 10, an opening is provided on the surface opposite to the connecting portion 12. Here, the suction tube 3 provided with the suction port 2 is shorter than the injection tube 8 provided with the injection port 7, and the suction port 2 is positioned behind the injection port 7 when aligned in the same direction. It has become.

また、回転軸14の回転によって発電するコイルなどから構成された発電機15及びその起電力を平滑して所定の直流電圧源とする電源回路16からなる発電手段17が連結部12近傍に配され、この発電手段17の電力を用いてLEDなどから構成された照明手段18が吸気口2近傍に配されている。   In addition, a generator 15 composed of a coil or the like that generates electricity by rotation of the rotating shaft 14 and a power generation means 17 including a power supply circuit 16 that smoothes the electromotive force to obtain a predetermined DC voltage source are arranged in the vicinity of the connecting portion 12. An illuminating means 18 composed of an LED or the like using the electric power of the power generating means 17 is disposed in the vicinity of the intake port 2.

以上のように構成された本実施の形態における空気噴射装置の動作、作用を説明する。   The operation and action of the air injection device in the present embodiment configured as described above will be described.

吸引室6の排出口4を、電気掃除機などの吸引作用を生み出すことができる吸引発生装置と連通接続されたホース(図示せず)もしくは延長管(図示せず)に連通接続し、吸引発生装置を運転する。すると排出口4から空気が吸引されることで、吸引口2より空気が吸引室6へ流入し、吸引ファン5を回転させる。   The exhaust port 4 of the suction chamber 6 is connected to a hose (not shown) or an extension pipe (not shown) connected to a suction generator capable of producing a suction action such as a vacuum cleaner, and suction is generated. Operate the device. Then, air is sucked from the discharge port 4 so that air flows into the suction chamber 6 from the suction port 2 and rotates the suction fan 5.

吸引ファン5の回転力は、軸受13で保持された回転軸14を介して噴射ファン10を回転させ、噴射ファン10が回転することで、第2の吸引口9より空気が噴射室11内に吸引されて圧縮されて、噴射管8の噴射口7より勢い良く外部に噴射される。噴射された空気は、掃除対象物に堆積した塵や埃を吹き飛ばし、吹き飛ばされた塵や埃は、その場で舞上がり、噴射口7の後方に位置する吸引口2より周辺の空気と一緒に吸引され回収される。   The rotational force of the suction fan 5 is such that the injection fan 10 is rotated via the rotation shaft 14 held by the bearing 13 and the injection fan 10 rotates, so that air is introduced into the injection chamber 11 from the second suction port 9. The air is sucked and compressed, and is ejected from the ejection port 7 of the ejection pipe 8 to the outside. The jetted air blows away dust and dirt accumulated on the object to be cleaned, and the blown-off dust and dust rises on the spot and is sucked together with the surrounding air from the suction port 2 located behind the jet port 7. And recovered.

このとき、回転軸14に連結された発電手段17では、回転軸14の回転力によって発電機15から生じる起電力を電源回路16で平滑し、照明手段18に電流を供給する。LEDなどで構成された照明手段18は、吸引口2の近傍で前方に照射し、塵埃の吸引状況を目視しやすくする。ブロアー機能を要する場所は、家具間のスキマや部屋の端、棚の溝など一般的な床面吸込具が使いにくい場所で、何らかの影になり暗い場合も多いが、本実施の形態では、LEDの照射によって、汚れている部分やその取り除かれ方も分かりやすい。   At this time, in the power generation means 17 connected to the rotary shaft 14, the electromotive force generated from the generator 15 by the rotational force of the rotary shaft 14 is smoothed by the power supply circuit 16 and the current is supplied to the illumination means 18. The illumination means 18 composed of an LED or the like irradiates forward in the vicinity of the suction port 2 so that the dust suction state can be easily seen. The place where the blower function is required is a place where it is difficult to use a general floor suction tool such as a gap between furniture, the edge of a room, a groove in a shelf, etc. It is easy to understand the dirty part and how to remove it by irradiation.

以上のように、本実施の形態によれば、吸引作用を発生させる吸引発生装置があれば、その種類は問わず吸引管3と吸引発生装置とを接続するだけで、吸引作用を噴射作用に変換でき、噴射で吹き飛ばした塵や埃も回収するとともに、照明によって状況が非常に把握
しやすい、極めて使い勝手が良く衛生的な空気噴射装置を提供することができる。
As described above, according to the present embodiment, if there is a suction generator that generates a suction action, the suction action can be changed to a jet action by simply connecting the suction pipe 3 and the suction generator regardless of the type. It is possible to provide a highly user-friendly and sanitary air jet apparatus that can convert and collect dust and dust blown off by jetting, and can easily grasp the situation by illumination.

また吸引だけの掃除では、ノズルなどの吸込口体を近接させる必要があり、掃除対象が吸い付いついて破損したり、傾いたり吸込んでしまったりし、吸引力の微調整は使い手側では難しい部分を、ブロアーだと離れた場所から作用して、使い手側が掃除対象の塵や埃のみを吹き飛ばす位置までの距離を調整することが出来、舞上がった塵や埃を周辺の空気と一緒に吸引出来るので、掃除対象に近接しなくても簡単に掃除できるようになる。また、照明があることで、離れることで影になって暗い部分の状況がつかみにくかったような課題も改善でき、掃除の効率も上げることができる。   In addition, when cleaning only by suction, it is necessary to bring the suction port body such as a nozzle close to the target, and the object to be cleaned will stick to it, break it, tilt it, or suck it, and fine adjustment of the suction force is difficult on the user side If it is a blower, it can work from a remote location, and the user can adjust the distance to the position where only the dust or dust to be cleaned is blown away, so that the dust and dust that rises can be sucked together with the surrounding air It becomes easy to clean even if it is not close to the object to be cleaned. In addition, the presence of lighting can improve the problem that it is difficult to grasp the situation of the dark part that is shadowed by leaving, and the efficiency of cleaning can be improved.

図3及び図4において、本実施の形態における空気噴射装置は、上記第2の実施の形態における空気噴射装置1の第2の吸引口9にシャッター構造を持つ開口面積調整手段23を設け、さらに開口面積調整手段23の調整を行うためのツマミやギアから構成された操作手段22と、たとえばエンコーダなどによる回転軸14の回転数を検知する回転数検知手段24を備えたものである。   3 and 4, the air injection device in the present embodiment is provided with an opening area adjusting means 23 having a shutter structure at the second suction port 9 of the air injection device 1 in the second embodiment, and An operating means 22 composed of a knob or gear for adjusting the opening area adjusting means 23 and a rotational speed detecting means 24 for detecting the rotational speed of the rotary shaft 14 by an encoder or the like are provided.

開口面積調整手段23のシャッター構造による開閉機構は一般的であるため詳細説明は省略する。また、回転数検知手段24の本来の目的は、噴射ファン10の回転数を検知す
ることであるが、電源回路16や判断手段20との構成上都合がよく、回転軸14の回転数からも一義的に求めることができるため、本実施の形態では、回転軸14の回転数を求める構造としている。
Since the opening / closing mechanism by the shutter structure of the opening area adjusting means 23 is common, detailed description thereof is omitted. The original purpose of the rotational speed detection means 24 is to detect the rotational speed of the injection fan 10, but it is convenient for the configuration with the power supply circuit 16 and the determination means 20, and from the rotational speed of the rotary shaft 14. Since it can be determined uniquely, the present embodiment has a structure for determining the rotational speed of the rotating shaft 14.

以上のように構成された本実施の形態における空気噴射装置の動作、作用は以下の通りである。   The operation and action of the air injection device according to the present embodiment configured as described above are as follows.

上記実施の形態で説明したように、吸引ファン5の回転力が噴射ファン10の回転となり第2の吸引口9より流入した空気を噴射するが、ここで第2の吸引口9の開口面積を調節することで、空気の噴射量を調節することができる。本来の吸引口2との距離を考慮した上で、ブロアー量を調節することで、さらに使い勝手を向上させることができる。このブロアー量は、第2の吸引口9の開口面積と噴射ファン10の回転数から決まってくるが、使用者は目視で開口面積はある程度判断できるが、回転数はなかなか分からない。   As described in the above embodiment, the rotational force of the suction fan 5 is the rotation of the ejection fan 10 and the air flowing in from the second suction port 9 is ejected. Here, the opening area of the second suction port 9 is increased. By adjusting, the amount of air injection can be adjusted. In consideration of the distance from the original suction port 2, the usability can be further improved by adjusting the blower amount. The blower amount is determined from the opening area of the second suction port 9 and the rotational speed of the jet fan 10, but the user can visually determine the opening area to some extent, but the rotational speed is not readily known.

そこで、本実施の形態では、この回転数を回転数検知手段24で検知し、さらに開口面積情報とあわせて判断手段20に送ることで、判断手段20はその計算を行い、表示手段21を用いて使用者に情報を報知できる。明確な表示ができるということは、単にその場所を掃除しているときだけでなく、時間が経過した後でも同じ設定を簡単に再現できるということになるので、所定の場所を所定の設定で同じように掃除でき、非常に使い勝手のよい空気噴射装置を提供することができる。   Therefore, in the present embodiment, the number of rotations is detected by the number-of-rotations detection unit 24 and further sent to the determination unit 20 together with the opening area information, so that the determination unit 20 performs the calculation and uses the display unit 21. Information to the user. Being able to display clearly means that the same settings can be easily reproduced not only when the place is being cleaned but also after a certain amount of time has passed, so the given place is the same with the given setting. It is possible to provide an air jet device that can be cleaned as described above and is very easy to use.

また、上記各実施の形態において、発電手段17が発電する電力は、吸引ファン5の回転数に依存することから、必ずしも安定しているとはいいがたい。そこで、発電手段17を構成する電源回路16の電圧をより安定化させるため大容量のキャパシタあるいは充電池などから構成された蓄電手段25を設けて、発電量に余裕がある場合には蓄電し、一時的に発電量が低下したときに蓄電手段15から補完するようにし、より安定した動作をすることができる。   Further, in each of the above embodiments, the power generated by the power generation means 17 depends on the number of rotations of the suction fan 5 and is not necessarily stable. Therefore, in order to further stabilize the voltage of the power supply circuit 16 constituting the power generation means 17, a power storage means 25 constituted by a large-capacity capacitor or a rechargeable battery is provided. When the amount of power generation is temporarily reduced, the power storage means 15 is complemented, and a more stable operation can be performed.

By connecting a hose (not shown) that the device 1 can be detachably attached to, a convenient electric cleaning that allows the air jet device 1 to be installed in a sanitary manner and blower cleaned while performing normal cleaning. Can provide a machine.

また、本実施の形態における空気噴射装置1に対応した電気掃除機と通信が行える無線式の通信手段26を設けて、塵埃検出手段19によって検出した塵埃量や開口面積調整手段23と回転数検知手段24から判断できるブロアー量などの情報を通信で送り、掃除機本体の吸引力を設定する電動送風機への電力供給量を制御する手段を装備することで、さらに使用者の使い勝手を向上した便利な電気掃除機を提供することもできる。   Further, a wireless communication means 26 capable of communicating with the vacuum cleaner corresponding to the air injection device 1 in the present embodiment is provided, and the dust amount and opening area adjustment means 23 detected by the dust detection means 19 and the rotational speed detection are detected. Convenient to further improve the usability of the user by providing means to control the power supply amount to the electric blower that sends information such as the blower amount that can be judged from the means 24 by communication and sets the suction power of the cleaner body A simple vacuum cleaner can also be provided.

以上のように、本発明にかかる空気噴射装置及びそれを用いた電気掃除機は、吸引室に作用する吸引力で噴射口から空気を噴射し、かつ発電手段による電力で吸引状況を把握することができるので、吸引発生装置の形態に左右されず、通常の吸引では掃除しにくい場所を効率よく簡単に掃除できるもので、業務用、家庭用の各種電気掃除機に適用できるものである。   As described above, the air injection device according to the present invention and the vacuum cleaner using the same inject air from the injection port with the suction force acting on the suction chamber and grasp the suction state with the electric power generated by the power generation means. Therefore, it is possible to efficiently and easily clean a place that is difficult to clean by normal suction, regardless of the form of the suction generator, and can be applied to various electric and household vacuum cleaners.
