特許文献１における寝具用吸込口体の場合、左右一対の車輪が筐体の前端面よりも前方へ突出しているため、例えば、ベッド上を清掃すると、ベッドのヘッドボードに一対の車輪が当たって傷を付けるおそれがある。また、ベッドが壁際に設置されていると一対の車輪によって壁を傷つけるおそれもある。 In the case of the bedding suction port body in Patent Document 1, since the pair of left and right wheels project forward from the front end surface of the housing, for example, when the bed is cleaned, the pair of wheels hit the headboard of the bed. There is a risk of scratching. Also, if the bed is installed near a wall, the pair of wheels may damage the wall.

また、特許文献１における寝具用吸込口体の場合、左右一対の車輪が振動部材よりも被掃除面側に突出していることは、振動部材の被掃除面への吸い付きを抑制して被掃除面に対する寝具用吸込口体の前後移動をスムーズに行うのに有効であるが、左右一対の車輪は大きいため電気掃除機全体の重量が増加し、清掃時に使用者の腕が疲れやすくなる。 Further, in the case of the suction port body for bedding in Patent Document 1, the fact that the pair of left and right wheels protrude toward the surface to be cleaned from the vibrating member suppresses the sticking of the vibrating member to the surface to be cleaned and is cleaned. It is effective for smoothly moving the bedding suction port back and forth with respect to the surface, but since the pair of left and right wheels are large, the weight of the entire vacuum cleaner increases, and the user's arm tends to get tired during cleaning.

また、特許文献２における吸込口体は、ソールプレートの前端部に反り返った前側エッジを有するが、前側エッジはベッド上を清掃するときに生じるヘッドボードや壁への衝突による傷付きを抑制するバンパーとしての機能を有していない。また、吸込口体の筐体の底面に大きなソールプレートが設けられることで重量増加にもなっていた。 Further, the suction port body in Patent Document 2 has a front edge that is curved back to the front end portion of the sole plate, and the front edge is a bumper that suppresses damage due to collision with the headboard or wall that occurs when cleaning the bed. Does not have the function as. In addition, a large sole plate is provided on the bottom surface of the suction port housing, which increases the weight.

本発明は、このような課題に鑑みなされたものであり、ベッドや壁に対する傷付き抑制および軽量化できる寝具用吸込口体を提供することを目的とする。 The present invention has been made in view of such problems, and an object of the present invention is to provide a bedding suction port that can suppress damage to a bed or a wall and reduce the weight.

かくして、本発明によれば、吸込口を底面に有する左右方向に長い筐体と、前記筐体の左右方向に長い前端部に沿って取り付けられたバンパーとを有し、
前記バンパーが、前記筐体に固定される固定部と、前記固定部の下端部から前方に突出しかつ上方へ折り返された折り返し部とを有する電気掃除機の寝具用吸込口体が提供される。 Thus, according to the present invention, there is a housing that is long in the left-right direction and has a suction port on the bottom surface, and a bumper that is attached along the front end portion that is long in the left-right direction of the housing.
Provided is a bedding suction port for a vacuum cleaner having a fixing portion in which the bumper is fixed to the housing and a folded portion that protrudes forward from the lower end portion of the fixing portion and is folded upward.

本発明によれば、寝具用吸込口体にてベッド上を清掃する際、バンパーの先端部が上方へ折り返されているため、ベッドのヘッドボードあるいは壁等にバンパーが接触したとしても、それらにはバンパーの先端部が面接触する。それに加え、横断面Ｕ形またはＪ形に形成されたバンパーは面接触時に弾性変形して衝撃を緩和することができるため、ベッドのヘッドボードあるいは壁等への傷付きを抑制することができる。
また、本発明の寝具用吸込口体は、従来のように寝具上（例えば、布団上）でスムーズな往復移動を実現させるために設けられる左右一対の車輪やソールプレートを有さないため軽量化できる。 According to the present invention, when cleaning the bed with the bedding suction port, the tip of the bumper is folded upward, so that even if the bumper comes into contact with the headboard or wall of the bed, they can be touched. The tip of the bumper comes into surface contact. In addition, the bumper formed in a U-shaped or J-shaped cross section can be elastically deformed at the time of surface contact to alleviate the impact, so that damage to the headboard or wall of the bed can be suppressed.
Further, the suction port body for bedding of the present invention is lightweight because it does not have a pair of left and right wheels or a sole plate provided for smooth reciprocating movement on the bedding (for example, on a futon) as in the conventional case. it can.

また、図９（Ｂ）に示すように、自重により下方へ揺動した揺動片２１ｅ1の第２段部２１ｅ112がストッパ凸部２１ａ124に当接した状態においては、揺動片２１ｅ1が筐体２１ａから下方外部に突出し、筐体２１ａの底面２１ａｘからの車輪２１ｅ2の突出が最大突出寸法Ｘ2になっている。 Further, as shown in FIG. 9B, when the second stage portion 21e 112 of the swing piece 21e 1 swinging downward due to its own weight is in contact with the stopper convex portion 21a 124 , the swing piece 21e 1 Projects downward and outward from the housing 21a, and the protrusion of the wheels 21e 2 from the bottom surface 21ax of the housing 21a has a maximum protrusion dimension X 2 .

揺動片２１ｅ1の揺動範囲は、筐体２１ａの底面２１ａｘに対する車輪２１ｅ2の突出が最小突出寸法Ｘ1〜最大突出寸法Ｘ2の範囲となるように設定されており、具体的には、最小突出寸法Ｘ1は１〜１０ｍｍの範囲に設定され、最大突出寸法Ｘ2は１０〜５０ｍｍの範囲に設定されている。
また、安全スイッチ２１ｅの車輪２１ｅ2の外径Ｄ1は１０〜４０ｍｍの範囲に設定されている（図１０参照）。 The swing range of the swing piece 21e 1 is set so that the protrusion of the wheel 21e 2 with respect to the bottom surface 21ax of the housing 21a is in the range of the minimum protrusion dimension X 1 to the maximum protrusion dimension X 2. The minimum protrusion dimension X 1 is set in the range of 1 to 10 mm, and the maximum protrusion dimension X 2 is set in the range of 10 to 50 mm.
Further, the outer diameter D 1 of the wheel 21e 2 of the safety switch 21e is set in the range of 10 to 40 mm (see FIG. 10).

揺動検知部２１ｅ3は、筐体２１ａの底面２１ａｘからの車輪２１ｅ2の突出が最大突出寸法Ｘ2になった状態またはその直前の状態のときの揺動片２１ｅ1の揺動状態を検知する。
実施形態１の場合、揺動検知部２１ｅ3は、回転体駆動部２１ｄのモータ２１ｄ1を駆動状態または停止状態に切り替える押しボタン式のスイッチ部２１ｅ31であり、車輪２１ｅ2の突出が最大突出寸法Ｘ2になるときの揺動片２１ｅ1がスイッチ部２１ｅ31のボタン２１ｅ311を押すように、筐体２１ａの底面２１ａｘ側に固定されている。 The rocking detection unit 21e 3 detects the rocking state of the rocking piece 21e 1 when the protrusion of the wheel 21e 2 from the bottom surface 21ax of the housing 21a reaches the maximum protruding dimension X 2 or immediately before that. To do.
In the case of the first embodiment, the swing detection unit 21e 3 is a push button type switch unit 21e 31 that switches the motor 21d 1 of the rotating body drive unit 21d to the drive state or the stop state, and the protrusion of the wheel 21e 2 is the maximum protrusion. The swing piece 21e 1 when the dimension X 2 is reached is fixed to the bottom surface 21ax side of the housing 21a so as to push the button 21e 311 of the switch portion 21e 31 .

この揺動検知部２１ｅ3によれば、スイッチ部２１ｅ31のボタン２１ｅ311が押されると、回転体駆動部２１ｄのモータ２１ｄ1が駆動状態から停止状態に切り替わり、それによって回転体２１ｃの回転が停止する（図２参照）。 According to the swing detection unit 21e 3, when the button 21e 311 of the switch unit 21e 31 is pressed, the motor 21d 1 of the rotating body driving unit 21d switches from the driving state to the stopped state, whereby the rotating body 21c rotates. Stop (see FIG. 2).

ところで、フローリング、絨毯、畳等の床面上を清掃する一般的な床面用吸込口体（例えば、特開２０１３−６３１１４参照）に設けられた安全スイッチの場合、布団のように床面が大きく沈み込むことがないため、安全スイッチの車輪の最大突出寸法を５ｍｍ程度に小さく抑えることができる。 By the way, in the case of a safety switch provided on a general floor suction port (for example, refer to Japanese Patent Application Laid-Open No. 2013-63114) for cleaning the floor surface of flooring, carpets, tatami mats, etc., the floor surface is like a futon. Since it does not sink significantly, the maximum protruding dimension of the wheel of the safety switch can be suppressed to about 5 mm.

これに対し、本発明の寝具用吸込口体２０の場合、羽毛布団のような空気を多く含んだ柔らかい布団上を寝具用吸込口体２０にて清掃する際、床面用吸込口体と同様に安全スイッチ２１ｅの車輪２１ｅ2の最大突出寸法を小さく設定すると、柔らかい布団に車輪２１ｅ2が少し沈み込んでも回転体駆動部２１ｄのモータ２１ｄ1を駆動状態から停止状態に切り替えてしまう誤作動が発生するおそれがある。 On the other hand, in the case of the bedding suction port 20 of the present invention, when cleaning a soft duvet containing a large amount of air such as a duvet with the bedding suction port 20, the same as the floor suction port body. If the maximum protrusion dimension of the wheel 21e 2 of the safety switch 21e is set small, even if the wheel 21e 2 is slightly submerged in the soft futon, the motor 21d 1 of the rotating body drive unit 21d may be switched from the driving state to the stopped state. It may occur.

そのため、本発明では、柔らかい布団上を寝具用吸込口体２０にて清掃する際に、柔らかい布団に車輪２１ｅ2がある程度大きく沈み込んでも回転体駆動部２１ｄのモータ２１ｄ1を駆動状態から停止状態に切り替えないように、筐体２１ａの底面２１ａｘに対する車輪２１ｅ2の突出が最大突出寸法Ｘ2１０〜５０ｍｍの範囲に設定されている。また、車輪２１ｅ2の外径Ｄ1を１０〜４０ｍｍの範囲に設定することにより、柔らかく凹凸が大きい布団上でも車輪２１ｅ2として機能することができ、寝具用吸込口体２０のスムーズな前後移動を実現できる。 Therefore, in the present invention, when cleaning the soft futon with the bedding suction port body 20, even if the wheels 21e 2 sink to some extent in the soft futon, the motor 21d 1 of the rotating body driving unit 21d is stopped from the driving state. The protrusion of the wheel 21e 2 with respect to the bottom surface 21ax of the housing 21a is set in the range of the maximum protrusion dimension X 2 10 to 50 mm so as not to switch to. Further, by setting the outer diameter D 1 of the wheel 21e 2 in the range of 10 to 40 mm, the wheel 21e 2 can function as the wheel 21e 2 even on a soft and uneven futon, and the suction port body 20 for bedding can move smoothly back and forth. Can be realized.

実施形態２の寝具用吸込口体１２０は、バンパー１２１ｂの構成が実施形態１とは異なる以外は、実施形態１と同様である。以下、実施形態２における実施形態１とは異なる点を主に説明する。 (Embodiment 2)
FIG. 12 is a bottom view of the bedding suction port body of the second embodiment. In FIG. 12, the same reference numerals are given to the same elements as those in FIG.
The bedding suction port 120 of the second embodiment is the same as that of the first embodiment except that the configuration of the bumper 121b is different from that of the first embodiment. Hereinafter, the points different from the first embodiment in the second embodiment will be mainly described.

実施形態２におけるバンパー１２１ｂは、実施形態１におけるバンパー１２ｂと同様の基本構成を備えるが、下面に形成された複数の溝部１２１ｂ21は前後方向に対して斜め方向に延びている。
具体的に実施形態２の場合、各溝部１２１ｂ21は前方から後方へ向かうにつれて右から左へ傾いている。 The bumper 121b in the second embodiment has the same basic configuration as the bumper 12b in the first embodiment, but the plurality of groove portions 121b 21 formed on the lower surface extend obliquely in the front-rear direction.
Specifically, in the case of the second embodiment, each groove portion 121b 21 is tilted from right to left as it goes from the front to the rear.

このように各溝部１２１ｂ21を斜めにすることにより、寝具とバンパー１２１ｂの下面との密着箇所に溝部１２１ｂ21が移動してくるため、バンパー１２１ｂの下面への寝具の吸い付き抑制効果が向上する。 By tilting each groove 121b 21 in this way, the groove 121b 21 moves to the contact point between the bedding and the lower surface of the bumper 121b, so that the effect of suppressing the sticking of the bedding to the lower surface of the bumper 121b is improved. ..

実施形態３の寝具用吸込口体２２０も、バンパー２２１ｂの構成が実施形態１とは異なる以外は、実施形態１と同様である。以下、実施形態３における実施形態１とは異なる点を主に説明する。 (Embodiment 3)
FIG. 13 is a bottom view of the bedding suction port body of the third embodiment. In FIG. 13, the same reference numerals are given to the same elements as those in FIG.
The bedding suction port 220 of the third embodiment is also the same as the first embodiment except that the configuration of the bumper 221b is different from that of the first embodiment. Hereinafter, the points different from the first embodiment in the third embodiment will be mainly described.

実施形態３におけるバンパー２２１ｂも、実施形態１におけるバンパー１２ｂと同様の基本構成を備えるが、下面に形成された複数の溝部２２１ｂ21は前後方向に対して斜め方向に延びており、かつ右側の溝部２２１ｂ21の方向と左側の溝部２２１ｂ21の方向が逆向きとなっている。
具体的に実施形態３の場合、右側の各溝部２２１ｂ21は前方から後方へ向かうにつれて右から左へ傾き、左側の各溝部２２１ｂ21は前方から後方へ向かうにつれて左から右へ傾いている。 The bumper 221b in the third embodiment also has the same basic configuration as the bumper 12b in the first embodiment, but the plurality of groove portions 221b 21 formed on the lower surface extend obliquely in the front-rear direction and the groove portion on the right side. The direction of the 221b 21 and the direction of the groove portion 221b 21 on the left side are opposite.
Specifically, in the case of the third embodiment, each groove portion 221b 21 on the right side is inclined from right to left as it goes from front to rear, and each groove portion 221b 21 on the left side is inclined from left to right as it goes from front to rear.

このように各溝部２２１ｂ21を斜めにすることにより、実施形態２と同様に、寝具とバンパー２２１ｂの下面との密着箇所に溝部２２１ｂ21が移動してくるため、バンパー１２１ｂの下面への寝具の吸い付き抑制効果が向上する。それに加え、左右の溝部２２１ｂ２１が吸込口２１ａｗの左右中間位置へ向かって傾いているため、実施形態２と比較すると、左側の溝部２２１ｂ21への空気の流れがスムーズになる。 By tilting each groove 221b 21 in this way, the groove 221b 21 moves to the contact point between the bedding and the lower surface of the bumper 221b as in the second embodiment, so that the bedding on the lower surface of the bumper 121b The sticking suppression effect is improved. In addition, since the left and right groove portions 221b21 are inclined toward the left and right intermediate positions of the suction port 21aw, the air flow to the left side groove portion 221b 21 becomes smoother as compared with the second embodiment.
