Description
本発明は電気掃除機用付属品に係り、特に、掃除機本体に着脱可能に取り付けられている付属品（例えば、クリーナーヘッド）の内部構造を改良した電気掃除機用付属品に関する。
The present invention relates to an accessory for a vacuum cleaner, and in particular to an accessory for a vacuum cleaner with an improved internal structure for an accessory (e.g., a cleaner head) that is detachably attached to the vacuum cleaner body.
例えば、家庭等で使用される電気製品には、電気掃除機のように使用目的或いは使用環境に応じて掃除機本体に付属品を取り付けて使用するものがある。
For example, some electrical appliances used in the home, such as vacuum cleaners, have accessories that can be attached to the main body of the vacuum cleaner depending on the purpose or environment of use.
電気掃除機の場合、掃除機本体の吸引口に、クリーナーヘッドを長尺の管を介して或いは直接取り付けて床面等の掃除を行うが、床面の他に家具間の隙間や机上等、掃除の対象によっては、クリーナーヘッドに代えて、先端にブラシを備えた吸込ヘッドや、先端に吸込口を備えた細長い管状の吸込ヘッド等の付属品を、掃除機本体に取り付けて使用することが一般的である。
In the case of electric vacuum cleaners, the cleaner head is attached to the suction port of the vacuum cleaner body via a long tube or directly to clean floors, etc., but depending on the object to be cleaned other than floors, such as gaps between furniture or desks, it is common to attach accessories such as a suction head with a brush at the end or a long, thin tubular suction head with a suction port at the end to the vacuum cleaner body instead of the cleaner head.

The cleaner head (accessory) 2 also has at least one beater (two beaters 18a and 18b in this embodiment) adjacent to the dust collection brush section 10.
このビータ１８ａ及び１８ｂは、電気掃除機１００を操作することにより回転動作し、例えば、クリーナーヘッド２の吸口が布団に吸い付かないようにし、布団のごみを取りやすくしているものである。
The beaters 18a and 18b rotate when the vacuum cleaner 100 is operated, and, for example, prevent the suction nozzle of the cleaner head 2 from sticking to the futon, making it easier to remove dirt from the futon.
また、本実施例の流入口１２は、クリーナーヘッド２を清掃面に載置した際の鉛直方向視（上下方向から見た時）において、少なくともその一部がビータ１８ａと重なって形成されている。
In addition, in this embodiment, the inlet 12 is formed so that at least a portion of it overlaps with the beater 18a when viewed vertically (from above and below) when the cleaner head 2 is placed on the cleaning surface.
次に、第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７ｂは対向して配置され、第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７ｂのそれぞれの先端１６ａ１及び１６ｂ１と１７ａ１及び１７ｂ１が上向き斜めに傾斜、即ち、第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７ｂのそれぞれの先端１６ａ１及び１６ｂ１と１７ａ１及び１７ｂ１の上向き斜めの傾斜が、電気掃除機１００の進行方向に向かって傾斜していることによる効果を、図５（ａ）と図５（ｂ）及び図６を用いて説明する。
Next, the first inclined piles 16a and 16b and the second inclined piles 17a and 17b are arranged opposite each other, and the tips 16a1 and 16b1 and 17a1 and 17b1 of the first inclined piles 16a and 16b and the second inclined piles 17a and 17b are inclined obliquely upward, i.e., the upward inclination of the tips 16a1 and 16b1 and 17a1 and 17b1 of the first inclined piles 16a and 16b and the second inclined piles 17a and 17b is inclined toward the traveling direction of the vacuum cleaner 100. The effect of this will be explained using Figures 5(a), 5(b), and 6.
図５（ａ）及び図５（ｂ）は、電気掃除機１００の前進時（右矢印方向）及び後退時（左矢印方向）における第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７ｂの状態を示すクリーナーヘッド２の断面図である。
Figures 5(a) and 5(b) are cross-sectional views of the cleaner head 2 showing the state of the first inclined piles 16a and 16b and the second inclined piles 17a and 17b when the vacuum cleaner 100 moves forward (in the direction of the right arrow) and backward (in the direction of the left arrow).
図５（ａ）のＣ１部の拡大図及び図５（ｂ）のＣ２部の拡大図に示すように、第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７ｂのそれぞれの先端１６ａ１及び１６ｂ１と１７ａ１及び１７ｂ１が、電気掃除機１００の進行方向（前進又は後退）に向って傾斜しているので、前後動作のいずれにおいても塵埃を床面から絡み取りやすくなっている。
As shown in the enlarged view of part C1 in FIG. 5(a) and the enlarged view of part C2 in FIG. 5(b), the tips 16a1 and 16b1, and 17a1 and 17b1 of the first inclined piles 16a and 16b and the second inclined piles 17a and 17b, respectively, are inclined toward the direction of travel (forward or backward) of the vacuum cleaner 100, making it easier to pick up dust from the floor surface in both forward and backward movements.
図６は、電気掃除機１００の前進時における第１の傾斜パイル１６ａと第２の傾斜パイル１７ａ及び第１の傾斜パイル１６ｂと第２の傾斜パイル１７ｂにおけるそれぞれの先端１６ａ１と先端１７ａ１及び先端１６ｂ１と先端１７ｂ１の関係を示すクリーナーヘッド２の断面図である。
FIG. 6 is a cross-sectional view of the cleaner head 2 showing the relationship between the tips 16a1 and 17a1 of the first inclined pile 16a and the second inclined pile 17a, and between the tips 16b1 and 17b1 of the first inclined pile 16b and the second inclined pile 17b when the vacuum cleaner 100 moves forward.
図６のＡ部の拡大図及びＢ部の拡大図に示すように、対向する第１の傾斜パイル１６ａと第２の傾斜パイル１７ａ及び第１の傾斜パイル１６ｂと第２の傾斜パイル１７ｂにおけるそれぞれの先端１６ａ１と先端１７ａ１及び先端１６ｂ１と先端１７ｂ１は、どちらも同じ向きに傾斜しているため、塵埃が、第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７bのそれぞれの先端１６ａ１及び１６ｂ１と１７ａ１及び１７ｂ１が引っ掛かることなく内部に取り込まれるので、集塵ブラシ部１０に付着した塵埃を内部に搬送しやすくなる。
As shown in the enlarged view of part A and the enlarged view of part B in FIG. 6, the tips 16a1 and 17a1 of the opposing first inclined piles 16a and 17a, and the tips 16b1 and 17b1 of the opposing first inclined piles 16b and 17b are inclined in the same direction, so that dust is taken in without getting caught by the tips 16a1 and 16b1 of the opposing first inclined piles 16a and 16b, and the tips 17a1 and 17b1 of the opposing second inclined piles 17a and 17b, and therefore dust attached to the dust collection brush section 10 can be easily transported to the inside.
また、塵埃が前除塵体１１ａに配置されている第２の傾斜パイル１７ａに移り（第２の傾斜パイル１７ａの先端１７ａ１が逆目となっている）、集塵ブラシ部１０が綺麗になる（クリーニングされる）。
The dust also moves to the second inclined pile 17a arranged on the front dust removal body 11a (the tip 17a1 of the second inclined pile 17a has a reverse grain), and the dust collection brush section 10 becomes clean (is cleaned).
なお、特に詳述しないが、電気掃除機１００の後退時においても、上記した電気掃除機１００の前進時と同様な作用で、塵埃の回収と集塵ブラシ部１０のクリーニングが行なわれる。
Although not described in detail, when the vacuum cleaner 100 moves backwards, dust is collected and the dust collection brush section 10 is cleaned in the same manner as when the vacuum cleaner 100 moves forward.
このような本実施例の構成によれば、傾斜パイルによる集塵機構を適用したものであっても、クリーナーヘッド（付属品）を構成する部品（集塵ブラシ部１０、除塵部１１、ビータ１８ａ及び１８ｂ等）の配置を工夫して掃除機吸口に最適配置することで、塵埃の吸引効率を向上させることができることは勿論、第１の傾斜パイル１６ａ及び１６ｂと第２の傾斜パイル１７ａ及び１７ｂのそれぞれの先端１６ａ１及び１６ｂ１と１７ａ１及び１７ｂ１が、電気掃除機１００の進行方向（前進又は後退）に向って傾斜しているので、前後動作のいずれにおいても塵埃を床面から絡み取りやすくなっているし、集塵ブラシ部１０に付着した塵埃を内部に搬送しやすくなると共に、集塵ブラシ部１０のクリーニングを行うことができる。
With the configuration of this embodiment, even if a dust collection mechanism using inclined piles is applied, the parts that make up the cleaner head (accessory) (dust collection brush section 10, dust removal section 11, beaters 18a and 18b, etc.) can be optimally positioned at the vacuum cleaner suction port to improve the efficiency of dust suction. In addition, the tips 16a1 and 16b1 and 17a1 and 17b1 of the first inclined piles 16a and 16b and the second inclined piles 17a and 17b are inclined toward the direction of travel of the vacuum cleaner 100 (forward or backward), making it easier to pick up dust from the floor surface in both forward and backward movements, and making it easier to transport dust attached to the dust collection brush section 10 to the inside, as well as cleaning the dust collection brush section 10.
