Description

本願発明は、布団や寝具等の軟らかい被清掃面の塵埃を捕集する電気掃除機に関するものである。   The present invention relates to a vacuum cleaner that collects dust on a soft surface to be cleaned such as a futon or bedding.
従来、この種の寝具のような掃除対象物の掃除を行う真空掃除機は、上下運動により掃除対象物に打撃を与えて異物を脱落させる埃叩きと、回転により掃除対象物から異物を払い落とす円筒状ブラッシュとが単一の駆動源によって連動されて掃除対象物から異物を効率的に除去しながら集塵効率を向上させているものがあった(例えば、特許文献1参照)。   Conventionally, a vacuum cleaner that cleans an object to be cleaned such as this type of bedding wipes off the foreign object from the object to be cleaned by rotating the dust by hitting the object to be cleaned by moving up and down and rotating the object. Some cylindrical brushes are linked by a single drive source to improve the dust collection efficiency while efficiently removing foreign substances from the object to be cleaned (see, for example, Patent Document 1).

A screw hole 25 is formed in the rear position of the air inlet 8 on the bottom surface of the cleaner body 1, and is screwed to both sides of the cleaner body 1 in the rear position of the rotary cleaning body storage chamber 16 on the bottom surface of the cleaner body 1. A hole 25 is formed. In the vacuum cleaner main body 1, a plurality of first protrusions 26 are arranged at intervals behind the cover body 6 on the bottom surface.
図6に示すように、第1突起部26の側面方向から見た形状は、前後方向の中央よりも吸気口8側(前方側)が、被清掃面方向に対し、最下部27となり、最下部27の前方及び後方が円弧となる形状に形成している。   As shown in FIG. 6, the shape of the first protrusion 26 viewed from the side surface direction is such that the intake port 8 side (front side) becomes the lowermost portion 27 with respect to the surface to be cleaned from the center in the front-rear direction. The front and rear of the lower part 27 are formed into a circular arc shape.
図10は、カバー体6と回転清掃体18を示す要部斜視図、図18は、カバー体を前方から見た斜視図、図19は、図18におけるC−C断面図である。カバー体6は、吸気口8及び吸気路10を覆うように掃除機本体1底面に装着される。   10 is a perspective view of a main part showing the cover body 6 and the rotary cleaning body 18, FIG. 18 is a perspective view of the cover body as viewed from the front, and FIG. 19 is a cross-sectional view taken along the line CC in FIG. The cover body 6 is attached to the bottom surface of the cleaner body 1 so as to cover the intake port 8 and the intake path 10.
カバー体6の前部には、掃除機本体1の係合孔24に係合する複数の係止爪28が設けられている。カバー体6には、掃除機本体1の螺合孔25に対応する位置に螺合爪29が設けられている。カバー体6は、係止爪28を係合孔24に係合して、係合孔24と係止爪28との係合を支点としてカバー体6を回転させ、螺合爪29を螺合孔25に螺合することで着脱自在に装着される。螺合爪29は、ドライバーやコインにより回転させること
ができる構成で、約90度程度の回転により係合、係脱を行うことが可能な構成としている。
A plurality of locking claws 28 that engage with the engagement holes 24 of the cleaner body 1 are provided at the front portion of the cover body 6. The cover body 6 is provided with a screwing claw 29 at a position corresponding to the screwing hole 25 of the cleaner body 1. The cover body 6 engages the engaging claw 28 with the engaging hole 24, rotates the cover body 6 with the engagement between the engaging hole 24 and the engaging claw 28 as a fulcrum, and screwed the engaging claw 29. It is detachably mounted by being screwed into the hole 25. The screwing claws 29 can be rotated by a driver or a coin, and can be engaged and disengaged by rotating about 90 degrees.
図3、図18に示すように、カバー体6には、吸気口8及び吸気路10に対応する位置に格子部からなる複数の吸込口30を形成している。カバー体6の吸込口30の前方位置には、回転清掃体18に対応して回転清掃体18の中央エリア部22及び複数の円筒部23が露出する開口部31を形成している。   As shown in FIGS. 3 and 18, the cover body 6 is formed with a plurality of suction ports 30 made of lattice portions at positions corresponding to the intake ports 8 and the intake passage 10. At the front position of the suction port 30 of the cover body 6, an opening 31 that exposes the central area portion 22 and the plurality of cylindrical portions 23 of the rotary cleaning body 18 is formed corresponding to the rotary cleaning body 18.
開口部31間には、リブ部32を形成し、リブ部32により開口部31間を区画している。リブ部32は、複数の円筒部23との間の隙間部分と、中央エリア部22に設けた清掃部材の端部と近傍に配置した円筒部23との間の隙間部分に配置され、円筒部23は、リブ部32よりも下方に突出する外径に形成している。中央エリア部22に設けた一対のブラシ21も、リブ部32よりも下方に突出するように設定している。   Ribs 32 are formed between the openings 31, and the openings 31 are partitioned by the ribs 32. The rib portion 32 is disposed in a clearance portion between the plurality of cylindrical portions 23 and a clearance portion between the end portion of the cleaning member provided in the central area portion 22 and the cylindrical portion 23 disposed in the vicinity thereof. 23 is formed in the outer diameter which protrudes below rather than the rib part 32. As shown in FIG. The pair of brushes 21 provided in the central area part 22 is also set so as to protrude below the rib part 32.
円筒部23を露出させる開口部31の開口縁、特に、後方側の開口縁は、開口縁と円筒部23との隙間を狭くして、回転清掃体18の回転の際に、開口縁と円筒部23との間にシーツ等が巻き込まれないように構成している。   The opening edge of the opening 31 that exposes the cylindrical portion 23, particularly the opening edge on the rear side, narrows the gap between the opening edge and the cylindrical portion 23, and the rotation edge 18 and the cylinder are rotated when the rotary cleaning body 18 rotates. Sheets or the like are prevented from being caught between the portions 23.
カバー体6の中央付近にある吸込口30より後方位置には、螺合爪29の両側位置に、一対の第2突起部33が形成されている。第2突起部33は、第1突起部26と同様に、側面方向から見た形状は、略三角形状であり、三角形の頂部が被清掃面方向に対する最下部34となり、最下部34の位置は、二等辺三角形の中央よりも前後方向に吸気口8側(前方側)に片寄って配置されており、最下部34の前方及び後方が円弧となる形状に形成している。   A pair of second protrusions 33 are formed at positions on both sides of the screwing claw 29 at a position behind the suction port 30 near the center of the cover body 6. Similarly to the first protrusion 26, the second protrusion 33 has a substantially triangular shape when viewed from the side, and the top of the triangle is the lowermost part 34 with respect to the surface to be cleaned, and the position of the lowermost part 34 is Further, they are arranged so as to be offset toward the intake port 8 side (front side) in the front-rear direction with respect to the center of the isosceles triangle, and the front and rear of the lowermost part 34 are formed in a circular arc shape.
第1突起部26と第2突起部33は、お互いの最下部27、最下部34が同じ高さになるように下方に向かって突出している。   The first protrusion 26 and the second protrusion 33 protrude downward so that the lowermost portion 27 and the lowermost portion 34 of each other have the same height.
左右方向(回転清掃体18の長手方向)で最も外側に位置するカバー体6の吸込口30の外側の開口縁は、外側に位置する第1突起部26の外側の側面とほぼ同じ位置に形成されている。   An opening edge on the outer side of the suction port 30 of the cover body 6 located on the outermost side in the left-right direction (longitudinal direction of the rotary cleaning body 18) is formed at substantially the same position as the outer side surface of the first protrusion 26 located on the outer side. Has been.
また、最も内側に位置する吸気口8と対面する吸込口30の外側の開口縁は、第2突起部33の外側の側面とほぼ同じ位置に形成されている。これにより、シーツ等は、リブ部32と第1突起部26及び第2突起部33により押さえられて、吸込口30に吸い付くのを抑制することができる。   Further, the outer opening edge of the suction port 30 facing the innermost intake port 8 is formed at substantially the same position as the outer side surface of the second protrusion 33. Thereby, the sheet or the like can be suppressed from being sucked into the suction port 30 by being pressed by the rib portion 32, the first protrusion portion 26, and the second protrusion portion 33.
また、図3に示すように、第1突起部26と第2突起部33は、最下部27、34が一直線上に位置するように配設されている。第2突起部33の間に螺合爪29が位置しているので、掃除機本体1を布団等の上に載置した際、シーツ等は、両側に位置する第2突起部33により押さえられて螺合爪29に接触することはなく、掃除機本体1を前方向、或いは後方向に移動させる際、螺合爪29にシーツ等が接触して螺合爪29の螺合が外れることを防止することができる。   As shown in FIG. 3, the first protrusion 26 and the second protrusion 33 are arranged so that the lowermost portions 27 and 34 are positioned on a straight line. Since the screwing claws 29 are located between the second protrusions 33, when the cleaner body 1 is placed on a futon or the like, the sheets or the like are pressed by the second protrusions 33 located on both sides. Therefore, when the cleaner body 1 is moved forward or backward, a sheet or the like comes into contact with the screw claw 29 and the screw claw 29 is unscrewed. Can be prevented.
図3、図6に示すように、カバー体6の前方には、開口部31の両側位置に、平坦部35を形成しており、平坦部35は、第1突起部26と第2突起部33の最下部27、34と同じ高さになるように形成されている。平坦部35と両外側に位置する第1突起部26との間に、両側に位置する螺合爪29が位置するよう形成している。   As shown in FIGS. 3 and 6, flat portions 35 are formed in front of the cover body 6 at both side positions of the opening portion 31, and the flat portions 35 are formed by the first protrusion portion 26 and the second protrusion portion. It is formed to be the same height as the lowermost portions 27 and 34 of 33. Between the flat part 35 and the 1st projection part 26 located in the both outer sides, it forms so that the screwing nail | claw 29 located in both sides may be located.
平坦部35と両側に位置する第1突起部26との間に両側に位置する螺合爪29が位置
しているので、掃除機本体1を布団等の上に載置した際、シーツ等は、平坦部35と第1突起部26により押さえられて螺合爪29に接触することはなく、掃除機本体1を前方向、或いは後方向に移動させる際、螺合爪29にシーツ等が接触して螺合爪29の螺合が外れることを防止することができる。
Since the screwing claws 29 located on both sides are located between the flat portion 35 and the first protrusions 26 located on both sides, when the cleaner body 1 is placed on a futon or the like, The sheet is not touched by the flat portion 35 and the first protrusion 26 and does not come into contact with the screwing claw 29. When the cleaner body 1 is moved forward or backward, a sheet or the like comes into contact with the screwing claw 29. Thus, the screwing claw 29 can be prevented from being unscrewed.

FIG. 14 is an AA sectional view of FIG. 13 of the vacuum cleaner, FIG. 15 is an AA sectional view of FIG. 13 in a state where the vacuum cleaner is turned upside down, and FIG. 16 is a rotation of the cleaner. It is a principal part perspective view which shows the state which the body and the rotation detection sensor combined.
図11及び図12に示すように、第1突起部26と第2突起部33の後方位置には、凹設部36が形成され、凹設部36には、多数の突出部37を突出形成した回転体38が回転自在に支持されている。   As shown in FIGS. 11 and 12, a recessed portion 36 is formed at the rear position of the first protruding portion 26 and the second protruding portion 33, and a large number of protruding portions 37 are formed in the recessed portion 36. The rotating body 38 is rotatably supported.
回転体38は、回転軸39の両側を掃除機本体1内部で軸受け部40により軸支され、一方の回転軸39に、回転体38の回転を検出する回転検出センサー41が配設される。   The rotating body 38 is supported on both sides of the rotating shaft 39 by a bearing 40 inside the cleaner body 1, and a rotation detecting sensor 41 for detecting the rotation of the rotating body 38 is disposed on one rotating shaft 39.
図12、図13、図14、図15及び図16に示すように、回転検出センサー41は、上筐体42と下筐体43からなる筐体44を備えている。筐体44内に位置する回転軸45には、複数のスリット46を有する回転板47が回転軸45に対する回転を阻止された状態に固定されている。   As shown in FIGS. 12, 13, 14, 15, and 16, the rotation detection sensor 41 includes a housing 44 including an upper housing 42 and a lower housing 43. A rotating plate 47 having a plurality of slits 46 is fixed to the rotating shaft 45 located in the housing 44 in a state in which rotation with respect to the rotating shaft 45 is prevented.
また、筐体44内に位置する回転軸45には、回転板47に隣接して振り子板48が装着されている。振り子板48は、一部を切欠した略三日月状に形成し、回転軸45に対して回動可能に装着されている。   In addition, a pendulum plate 48 is attached to the rotating shaft 45 located in the housing 44 adjacent to the rotating plate 47. The pendulum plate 48 is formed in a substantially crescent shape with a part cut away, and is attached to the rotary shaft 45 so as to be rotatable.
振り子板48は、回転軸45に対して回動可能に装着されているため、図14〜図16に示すように、例えば、掃除機本体1が上下反転した際には、振り子板48は、自重により回転する。   Since the pendulum plate 48 is mounted so as to be rotatable with respect to the rotation shaft 45, as shown in FIGS. 14 to 16, for example, when the cleaner body 1 is turned upside down, the pendulum plate 48 is It rotates by its own weight.
筐体44内には、光センサー49を装着している。光センサー49は、発光素子50と受光素子51との間に回転板47と振り子板48を挟むように配設して構成している。光センサー49は、回転体38が回転すると、回転板47が回転して、発光素子50と受光素子51との間の光の受光状態において、回転板47のスリット46が位置する際の光が受光される受光状態と、スリット46が位置せず光が途絶え遮光状態とが連続することを検知することで回転体38の回転を検出する。   An optical sensor 49 is mounted in the housing 44. The optical sensor 49 is configured by arranging a rotating plate 47 and a pendulum plate 48 between the light emitting element 50 and the light receiving element 51. In the optical sensor 49, when the rotating body 38 rotates, the rotating plate 47 rotates, and the light when the slit 46 of the rotating plate 47 is positioned in the light receiving state between the light emitting element 50 and the light receiving element 51. The rotation of the rotating body 38 is detected by detecting that the light receiving state in which light is received and that the slit 46 is not positioned and light is interrupted and the light blocking state continues.
光センサー49は、回転体38の回転を検出すると、図示しない制御部に検出信号を送信し、制御部は、検出信号が一定の閾値を越えた際に、回転体38が被清掃面上で清掃動作が開始された状態と判断し、電動機20を駆動させる。前記閾値の設定としては、掃除機本体1を持ち上げた状態で、回転体38に手が触れる程度の少しの回転では電動機20が駆動しないように、0.5秒間の間に2回以上、光の受光状態が受光と否受光が続いた状態になった時点を閾値として設定している。   When the rotation of the rotating body 38 is detected, the optical sensor 49 transmits a detection signal to a control unit (not shown). When the detection signal exceeds a certain threshold value, the control unit 38 moves the rotating body 38 on the surface to be cleaned. It is determined that the cleaning operation has started, and the electric motor 20 is driven. The threshold value is set such that, with the vacuum cleaner body 1 lifted, the electric motor 20 is not driven by a slight rotation that touches the rotating body 38, so that the light 20 is driven twice or more in 0.5 seconds. Is set as a threshold value when the light receiving state is a state in which light receiving and non-light receiving continue.
また、電動送風機15は、回転検出センサー41の出力にかかわりなく、電源スイッチ7の操作によって駆動する。   Further, the electric blower 15 is driven by the operation of the power switch 7 regardless of the output of the rotation detection sensor 41.
電動機20が駆動されると、回転清掃体18が回転し、回転清掃体18の中央エリア部22に配置した一対のブラシ21が、布団や毛布、寝具等の軟らかい被清掃面に対して接
触して内部の塵埃をたたき出し、また回転清掃体18の中央エリア部22以外の両サイドに間隔を有して設けられた複数の円筒部23の回転により、上記被清掃面に対して前方方向に自走するため、軽操作で清掃作業を行うことができる。その際、複数の円筒部23の表面に起毛布をリング状に巻回して形成することにより、上記被清掃面にある塵埃をかき取る作用と、上記被清掃面との滑りが減り自走作用が高まる効果が生まれる。
When the electric motor 20 is driven, the rotary cleaning body 18 rotates, and the pair of brushes 21 arranged in the central area portion 22 of the rotary cleaning body 18 come into contact with a soft surface to be cleaned such as a futon, a blanket, and bedding. The internal dust is knocked out, and the rotation of the plurality of cylindrical portions 23 provided at intervals on both sides other than the central area portion 22 of the rotary cleaning body 18 automatically moves forward with respect to the surface to be cleaned. Because it runs, it can be cleaned with a light operation. At that time, a brushed cloth is wound around the surface of the plurality of cylindrical portions 23 to form a ring shape, so that the dust on the surface to be cleaned can be scraped off, and the sliding with the surface to be cleaned can be reduced. The effect that increases is born.
掃除機本体1を上下反転させた状態では、図15に示すように、振り子板48が自重により回転して、発光素子50と受光素子51との間に移動し、遮光状態となる。   In the state where the vacuum cleaner body 1 is turned upside down, as shown in FIG. 15, the pendulum plate 48 rotates by its own weight, moves between the light emitting element 50 and the light receiving element 51, and enters a light shielding state.
この上下反転させた状態で、回転体38を回しても、光センサー49は、光の受光が途絶えた遮光状態の検出信号を制御部に送信するため、制御部は、検出信号が一定の閾値を越えていないと判断し、電動機20を停止させる。   Even if the rotating body 38 is rotated in the upside down state, the optical sensor 49 transmits a detection signal in a light-shielded state in which light reception is interrupted to the control unit. Therefore, the electric motor 20 is stopped.
これにより、掃除機本体1を上下反転させた状態では、回転体38が静止した状態でも、誤って手や物が触れて回してしまった状態でも、回転清掃体18は回転せず、不用意に手指等が回転する回転清掃体18に触れる恐れを防止することができる。   Thereby, in the state where the vacuum cleaner body 1 is turned upside down, the rotating cleaning body 18 does not rotate and is careless even if the rotating body 38 is stationary or accidentally touched and turned by a hand or an object. It is possible to prevent the fingers from touching the rotating cleaning body 18 that rotates.
回転体38の両サイドに各々配置された回転軸39の軸受け部40は、掃除機本体1の外郭底面に覆われており、その軸受け部40を覆う外郭底面の各々には円弧状の膨出部52が膨出形成されている。   The bearing portions 40 of the rotary shaft 39 disposed on both sides of the rotating body 38 are covered with the outer bottom surface of the cleaner body 1, and each of the outer bottom surfaces covering the bearing portion 40 has an arcuate bulge. The part 52 is bulged.
図6、図20に示すように、円弧状の膨出部52が被清掃面と接地する最下部53は、回転体38の突出部37の最下部54よりも下方に位置するように構成し、膨出部52が、回転体38の近傍に配置され、掃除機本体1の載置面として支え受ける構成としている。   As shown in FIGS. 6 and 20, the lowermost portion 53 where the arcuate bulged portion 52 contacts the surface to be cleaned is configured to be positioned below the lowermost portion 54 of the protruding portion 37 of the rotating body 38. The bulging portion 52 is disposed in the vicinity of the rotating body 38 and is configured to be supported as a mounting surface of the cleaner body 1.
これにより、平坦な面やタフテッドカーペットなど、比較的、掃除機本体1が沈みにくい設置面に載置した際には、膨出部52が先に接地することにより、回転体38が設置面に接触せず、掃除機本体1を移動させても回転検出センサー41は、掃除機本体1の移動を検出することはなく、電動機20を駆動させることがない。   As a result, when the cleaner body 1 is placed on an installation surface that is relatively difficult to sink, such as a flat surface or tufted carpet, the bulging portion 52 is grounded first, so that the rotating body 38 is installed on the installation surface. The rotation detection sensor 41 does not detect the movement of the cleaner main body 1 and does not drive the electric motor 20 even if the cleaner main body 1 is moved without contacting the motor.
従って、掃除機本体1を掃除の対象となる布団や毛布、寝具等の軟らかい被清掃面等とは異なる設置面に載置して、掃除機本体1を移動させたとしても、掃除機本体1の回転清掃体18が回転し、使用者の意思に異なって不用意に、設置面上で動き移動するのを防止することができる。   Therefore, even if the cleaner body 1 is placed on an installation surface different from a soft surface to be cleaned such as a futon, blanket, or bedding to be cleaned, and the cleaner body 1 is moved, the cleaner body 1 Therefore, the rotating cleaning body 18 can be prevented from rotating and moving on the installation surface carelessly in accordance with the intention of the user.
また、掃除機本体1の後方には、車輪55が回転自在に支持されている。平坦部35、第1突起部26と第2突起部33の最下部27、34、膨出部52の最下部53及び車輪55の表面は、平坦面に掃除機本体1を置いた際に、それぞれ全てが接地するように形成されている。   A wheel 55 is rotatably supported behind the cleaner body 1. When the vacuum cleaner main body 1 is placed on a flat surface, the flat portion 35, the lowermost portions 27 and 34 of the first protruding portion 26 and the second protruding portion 33, the lowermost portion 53 of the bulging portion 52, and the surface of the wheel 55, Each is formed so as to be grounded.
上記構成において、掃除機本体1を布団等の上に載置し、電源スイッチ7をONし、取っ手4を把持して掃除機本体1を前方、または後方に移動させる。掃除機本体1の移動により回転体*38が回転し、回転体38の回転を回転検出センサー41が検出して制御部が電動機20及び回転清掃体18を回転駆動する。   In the above configuration, the cleaner body 1 is placed on a futon, the power switch 7 is turned on, the handle 4 is gripped, and the cleaner body 1 is moved forward or backward. The rotary body * 38 is rotated by the movement of the cleaner body 1, the rotation detection sensor 41 detects the rotation of the rotary body 38, and the control unit rotationally drives the electric motor 20 and the rotary cleaning body 18.
掃除機本体1の移動を停止、或いはほぼ停止状態にすると、回転体38の回転が停止、或いはほぼ停止状態となるので、回転体38の回転を回転検出センサー41が検出して制御部が回転清掃体18の回転を停止する。なお、電動送風機15は駆動を継続する。   When the movement of the cleaner body 1 is stopped or almost stopped, the rotation of the rotating body 38 is stopped or almost stopped, so that the rotation detecting sensor 41 detects the rotation of the rotating body 38 and the control unit rotates. The rotation of the cleaning body 18 is stopped. The electric blower 15 continues to be driven.
電動送風機15の駆動により、吸込口30から吸気路10及び吸気口8を介して塵埃や毛髪等が空気とともに吸引され、塵埃が集塵袋13内に捕集される。吸込口30は、掃除機本体1のほぼ全幅にわたって形成されているので、塵埃や毛髪等を効率よく除去することができる。また、開口部31から切欠部17を介して吸気口8を通して塵埃や毛髪等を除去することができる。   By driving the electric blower 15, dust, hair, and the like are sucked together with air from the suction port 30 through the intake passage 10 and the intake port 8, and the dust is collected in the dust collection bag 13. Since the suction port 30 is formed over substantially the entire width of the cleaner body 1, dust, hair, and the like can be efficiently removed. Further, dust, hair, and the like can be removed from the opening 31 through the air inlet 8 through the notch 17.
電動機20の回転により、回転清掃体18が前方(図6において反時計方向)に向かって回転し、起毛布からなる円筒部23とシーツ等との摩擦力により掃除機本体1が前方向に自走するように作用する。これにより、使用者は、ほとんど掃除機本体1を前方向に押す力を加えることなく、掃除機本体1を前方向に移動させることが可能となる。   As the electric motor 20 rotates, the rotary cleaning body 18 rotates forward (counterclockwise in FIG. 6), and the main body of the cleaner 1 automatically moves forward due to the frictional force between the cylindrical portion 23 made of brushed cloth and the sheets. Acts to run. Thereby, the user can move the cleaner main body 1 in the forward direction with almost no force for pushing the cleaner main body 1 in the forward direction.
回転清掃体18の回転により、ブラシ21及び起毛布からなる円筒部23の掻き上げ力によって、シーツ等に付着した塵埃や毛髪等を効率よく除去することができる。   Due to the rotation of the rotary cleaning body 18, dust, hair, and the like attached to the sheets and the like can be efficiently removed by the scraping force of the cylindrical portion 23 made of the brush 21 and the raised cloth.
回転清掃体18の回転によるブラシ21と円筒部23の掻き上げ力、及び電動送風機15の吸引力によりシーツ等が吸込口30に吸い付こうとするが、シーツ等は、リブ部32と第1突起部26及び第2突起部33により押さえられて、吸込口30に吸い付くのを抑制され、掃除機本体1の移動が妨げられるのを抑制することができる。   The sheet or the like tries to suck the suction port 30 by the scraping force of the brush 21 and the cylindrical portion 23 by the rotation of the rotary cleaning body 18 and the suction force of the electric blower 15. It is suppressed by the projection part 26 and the 2nd projection part 33, and it can suppress that it attracts | sucks to the suction inlet 30, and can suppress that the movement of the cleaner body 1 is prevented.
リブ部32に隣接して円筒部23が位置しているので、リブ部32のシーツ等に対する接触力は比較的弱く、リブ部32がシーツ等をいためる恐れは少ないため、リブ部32の幅は比較的少なくすることができ、シーツ等に対する摩擦力を低減して掃除機本体1の移動性を向上することができる。   Since the cylindrical portion 23 is located adjacent to the rib portion 32, the contact force of the rib portion 32 to the sheet or the like is relatively weak, and the rib portion 32 is less likely to damage the sheet or the like. It is possible to reduce the frictional force against the sheets and the like, and the mobility of the cleaner body 1 can be improved.
第1突起部26及び第2突起部33は、シーツ等を押さえてシーツ等が吸込口30に吸い付くのを抑制する作用を発揮するために、リブ部32に比較して幅広く形成している。実験的に効果的であったのは、吸込口30より後方に配置された複数の第1突起部26及び第2突起部33の回転清掃体18の長手方向の厚み寸法は、複数の円筒状の円筒部23の間隔寸法より小さい、3〜12mmの範囲に設定している。   The first protrusions 26 and the second protrusions 33 are formed wider than the ribs 32 in order to exert an effect of suppressing the sheets and the like and suppressing the sheets and the like from adhering to the suction port 30. . It was experimentally effective that the thickness dimension in the longitudinal direction of the rotary cleaning body 18 of the plurality of first protrusions 26 and the second protrusions 33 arranged behind the suction port 30 is a plurality of cylindrical shapes. Is set to a range of 3 to 12 mm, which is smaller than the distance between the cylindrical portions 23.
また、吸込口30より後方に配置された複数の第1突起部26及び第2突起部33の側面方向の形状は、複数の円弧を繋いだ略三角形状とし、この略三角形状の頂部位置、すなわち最下部27、34の位置が、掃除機本体1の前後進行方向に対し、吸込口30側に片寄って形成しているので、シーツ等を抑える作用をより向上することができ、シーツ等の開口部31への吸い付きをより確実に抑制することができる。   Further, the shape in the side surface direction of the plurality of first protrusions 26 and the second protrusions 33 arranged behind the suction port 30 is a substantially triangular shape connecting a plurality of arcs, and the top position of the substantially triangular shape, That is, since the positions of the lowermost portions 27 and 34 are formed so as to be offset toward the suction port 30 side with respect to the front-rear direction of the cleaner body 1, the action of suppressing the sheets can be further improved. The sticking to the opening 31 can be more reliably suppressed.
リブ部32は、前方側を高く形成しているので、掃除機本体1の前方向への移動が妨げられるのを抑制することが可能となる。また、リブ部32は、開口部31側を低く(被掃除面側に位置するように)形成しているので、シーツ等を抑える作用を向上することができ、シーツ等の開口部31へのすいつきをより確実に抑制することができる。   Since the rib part 32 forms the front side high, it becomes possible to suppress that the movement to the front direction of the cleaner body 1 is prevented. Further, since the rib portion 32 is formed so that the opening 31 side is low (so as to be located on the surface to be cleaned), the action of suppressing the sheet or the like can be improved, and the opening to the opening 31 such as the sheet can be improved. Soothing can be more reliably suppressed.
掃除を中断する場合など、掃除機本体1を上下反転させると、図15に示すように、振り子板48が自重により回転して、発光素子50と受光素子51との間に移動し、遮光状態となる。これにより、回転検出センサー41は、遮光状態の検出信号を制御部に送信し、制御部は、電動機20を停止して、回転する回転清掃体18に不用意に手指等が触れる恐れを防止することができる。   When the cleaner body 1 is turned upside down, for example, when cleaning is interrupted, as shown in FIG. 15, the pendulum plate 48 rotates due to its own weight and moves between the light emitting element 50 and the light receiving element 51 to block light. It becomes. Thereby, the rotation detection sensor 41 transmits a detection signal of a light shielding state to the control unit, and the control unit stops the electric motor 20 to prevent a finger or the like from touching the rotating rotating cleaning body 18 inadvertently. be able to.
以上のように、本発明にかかる掃除機は、シーツや布団の軟質生地を清掃する際に、電動機で回転する回転清掃体に備えたブラシや自走作用をもたらす円筒部およびリブ部と複
数の突起部により、シーツや布団の軟質生地が吸着によって回転清掃体に巻き込むのを防止しつつ、塵埃を効率良く吸塵し、さらに円筒部による自走作用により軽操作で清掃作業ができるため、家庭用ならびに業務用の掃除機として利用することができる。
As described above, the vacuum cleaner according to the present invention includes a brush provided in a rotary cleaning body that is rotated by an electric motor and a cylindrical portion and a rib portion that provide a self-propelling action when cleaning a soft cloth such as a sheet or a futon. The projections prevent the soft cloth of sheets and futons from being caught in the rotary cleaning body by adsorption, and efficiently absorb the dust. It can also be used as a commercial vacuum cleaner.
