Abstract

PROBLEM TO BE SOLVED: To provide a nozzle for a vacuum cleaner capable of preferably combing out fur or hair attached to a carpet, futon or the like with a light force without damaging the carpet or the like.SOLUTION: A long projection group 16 comprising a plurality of long projections 15, and a short projection group 18 comprising a plurality of short projections 17 are provided near a suction port 14 of the nozzle body 11. Each of the projections 15, 17 is comprised of a flexible material. The long projection group 16 combs out the fur or hair stuck into a deep part of the carpet C while sagging, and the short projection group 18 combs out the fur or hair on a surface part of the carpet C. Thus, not only the fur or hair attached to the carpet C can be effectively scraped up without damaging the carpet C, but also the resistance between the short projection group 18 and the carpet C can be reduced since the short projection group 18 combs as if it rubs the surface part of the carpet C. Therefore, the fur or hair can be preferably combed out with the relatively light force even though there are many projections.

Description

本発明は、電気掃除機のノズルに関するものであり、特に、絨毯やふとん等に付着した毛や髪を吸引するのに適した電気掃除機のノズルに関するものである。 The present invention relates to a nozzle of a vacuum cleaner, and more particularly to a nozzle of a vacuum cleaner suitable for sucking hair or hair attached to a carpet or a futon.

従来、この種の電気掃除機用ノズルとしては、真空掃除機の吸引管に対して着脱自在となるように構成されると共に、吸込口に沿う位置に、被清掃物の毛を梳くための間隔を保って並設した複数の梳歯を有する櫛状部（本願発明の突起群に相当する）を備えた吸込み具が知られている（例えば、特許文献１参照。）。この吸込み具は、絨毯等の被清掃物に櫛状部を押し当てて前後動させ、梳歯で被清掃物の毛を梳くようにしながら吸引することで、被清掃物の内部深くにあった塵埃を表面まで梳き出して、この梳き出された塵埃を吸込口から吸い込むことができる。 Conventionally, this type of vacuum cleaner nozzle is configured to be detachable with respect to the suction pipe of the vacuum cleaner, and the interval for combing the hair of the object to be cleaned at a position along the suction port. A suction tool having a comb-like portion (corresponding to the projection group of the present invention) having a plurality of toothed teeth arranged side by side is known (see, for example, Patent Document 1). This suction tool was deep inside the object to be cleaned by pressing the comb-like part against the object to be cleaned such as a carpet and moving it back and forth, and sucking it while combing the hair of the object to be cleaned with a toothpick. Dust can be sprinkled up to the surface, and the sprinkled dust can be sucked from the suction port.

しかしながら、このような電気掃除機用ノズルの突起群は、絨毯等を梳くために、硬い材質によって構成されていた。従って、突起群を絨毯や毛布等に強く押し付けることで、絨毯や毛布等を傷める虞があった。このような問題を回避するために、突起群をエラストマー等の可撓性を有する材質によって構成することが考えられる。しかしながら、このような突起群では、毛足の長い絨毯等に潜む抜け毛等を良好に梳き出すことができない虞があった。また、絨毯等に潜む抜け毛等を良好に梳き出すためには、突起群を構成する突起の数を増やし、多くの突起によって抜け毛等を絨毯等から梳き出すようにするのが効果的である。しかしながら、突起群を構成する突起の数が増えると、絨毯等を梳く際の抵抗が大きくなってしまうという問題もあった。更に、絨毯や毛布等から梳き出された抜け毛等が、突起群に絡んでしまう虞もあった。 However, such a group of protrusions of the vacuum cleaner nozzle is made of a hard material in order to spread a carpet or the like. Therefore, there is a possibility that the carpet or blanket may be damaged by strongly pressing the projection group against the carpet or blanket. In order to avoid such a problem, it is conceivable that the projection group is made of a flexible material such as an elastomer. However, in such a group of protrusions, there is a possibility that hair loss or the like lurking in a carpet having a long bristle or the like cannot be favorably sprinkled. Further, in order to scoop out hair loss hidden in a carpet or the like, it is effective to increase the number of protrusions constituting the protrusion group and to scoop out hair loss or the like from the carpet or the like with many protrusions. However, when the number of protrusions constituting the protrusion group is increased, there is a problem that resistance when the carpet or the like is spread increases. Furthermore, there is a possibility that hair fallen from a carpet or blanket may get entangled with the projection group.

本発明は以上の問題点を解決し、絨毯等を傷めることなく、軽い力で良好に絨毯やふとん等に付着した毛や髪を梳き出すことができる電気掃除機用ノズルを提供することを目的とする。 An object of the present invention is to provide a nozzle for an electric vacuum cleaner that can solve the above-mentioned problems and can comb out hair and hair attached to a carpet or a futon with a light force without damaging the carpet or the like. And

本発明の請求項１に記載の電気掃除機用ノズルは、吸込口を有するノズル本体と、このノズル本体の吸込口の近傍に設けられる突起群とを有する電気掃除機のノズルにおいて、前記突起群が、可撓性を有する材質で構成され、前記突起群が、複数の比較的長い突起からなる長突起群と、複数の比較的短い突起からなる短突起群とを有して構成されるものである。 The nozzle for a vacuum cleaner according to claim 1 of the present invention is the nozzle of a vacuum cleaner having a nozzle body having a suction port and a projection group provided in the vicinity of the suction port of the nozzle body. Is formed of a flexible material, and the protrusion group includes a long protrusion group including a plurality of relatively long protrusions and a short protrusion group including a plurality of relatively short protrusions. It is.

また、本発明の請求項２に記載の電気掃除機用ノズルは、請求項１において、前記突起群を構成する各突起が錐状であるものである。 Moreover, the nozzle for electric vacuum cleaners of Claim 2 of this invention is a thing in which each protrusion which comprises the said protrusion group is cone shape in Claim 1.

本発明の請求項１に記載の電気掃除機用ノズルは、以上のように構成することにより、前記長突起群が撓みながら絨毯等の深層部にある抜け毛等を梳き出すと共に、前記短突起群が撓みながら絨毯等の表層部にある抜け毛等を梳き出すことで、絨毯等を傷めることなく、効果的に絨毯等に付着した抜け毛等を掻き集め、吸引することができる。そして、前記短突起群が絨毯等の表層部を擦るように梳くことで、前記短突起群と絨毯等との抵抗を小さくすることができるので、突起数を多くしながらも、比較的軽い力で絨毯等から抜け毛等を良好に梳き出すことができる。 The nozzle for a vacuum cleaner according to claim 1 of the present invention is configured as described above, so that the long protrusions are bent and the hair coming out in a deep layer of a carpet or the like is curled out, and the short protrusions are By curling out the hair loss and the like on the surface layer of the carpet or the like while bending, the hair loss and the like attached to the carpet or the like can be effectively collected and sucked without damaging the carpet or the like. And since the resistance of the short projection group and the carpet or the like can be reduced by scratching the short projection group so as to rub the surface layer portion of the carpet or the like, a relatively light force can be obtained while increasing the number of projections. With this, it is possible to favorably remove hair loss from carpets.

また、前記突起群を構成する各突起を錐状としたことにより、前記突起群に絡んだ抜け毛等が、前記ノズルの動きに伴って、前記各突起の傾斜に沿って抜けるので、前記突起群に抜け毛等が絡み付かないようにすることができる。 Further, since each protrusion constituting the protrusion group has a conical shape, hair loss and the like entangled with the protrusion group come out along the inclination of each protrusion as the nozzle moves, so that the protrusion group The hair can be prevented from getting tangled.

The nozzle 3 is detachably attached to one end of the suction path of the connecting portion 7.

前記ノズル３について詳述する。このノズル３は、横長のノズル本体１１と、このノズル本体１１に対して回動可能に取り付けられる接続部材１２とを有して構成される。そして、前記ノズル本体１１は、その底面１３の中央に吸込口１４が形成される。また、この吸込口１４を挟むように、前記底面１３に、複数の長突起１５から構成される長突起群１６と、複数の短突起１７から構成される短突起群１８が設けられる。なお、前記各長突起１５及び短突起１７は、前記ノズル本体１１の下部に取り付けられる基部１９と一体に形成される。 The nozzle 3 will be described in detail. The nozzle 3 includes a horizontally long nozzle body 11 and a connecting member 12 that is rotatably attached to the nozzle body 11. The nozzle body 11 has a suction port 14 formed at the center of the bottom surface 13 thereof. Further, a long protrusion group 16 composed of a plurality of long protrusions 15 and a short protrusion group 18 composed of a plurality of short protrusions 17 are provided on the bottom surface 13 so as to sandwich the suction port 14. The long protrusions 15 and the short protrusions 17 are formed integrally with a base 19 attached to the lower part of the nozzle body 11.

前記各長突起１５及び短突起１７は、エラストマー等の軟質合成樹脂やシリコンゴム等、可撓性を有すると共に弾性変形可能な素材によってそれぞれ構成される。また、前記各長突起１５及び短突起１７は、それぞれ下端側が尖った略円錐状に形成される。なお、前記各長突起１５及び短突起１７は、図１及び図２に示すように、全体として円錐状であれば、その下端部を丸めた形状であっても良い。そして、前記長突起群１６は、一対の長突起列２０，２１により構成されると共に、前記短突起群１８は、一対の短突起列２２，２３により構成される。これらの長突起列２０，２１及び短突起列２２，２３は、それぞれ左右方向に延びて設けられる。また、前記各長突起列２０，２１及び短突起列２２，２３は、互いに平行に設けられる。そして、前記短突起列２２は、前記長突起列２０よりも後方に設けられる。また、前記短突起列２３は、前記長突起列２１よりも前方に設けられる。即ち、前記各短突起列２２，２３は、前記各長突起列２０，２１よりも前記吸込口１４に近い位置に設けられる。更に、前記各長突起列２０，２１を構成する長突起１５同士の間隔は、前記各短突起列２２，２３を構成する短突起１７同士の間隔と等しく構成されている。そして、前記各短突起１７は、図１に示すように、正面視で、前記各長突起１５の間に位置する。即ち、前記各長突起１５と短突起１７は、千鳥状に配列される。 Each of the long protrusions 15 and the short protrusions 17 is made of a flexible and elastically deformable material such as a soft synthetic resin such as elastomer or silicon rubber. Each of the long protrusions 15 and the short protrusions 17 is formed in a substantially conical shape with a sharpened bottom end. As shown in FIGS. 1 and 2, each of the long protrusions 15 and the short protrusions 17 may have a shape having a rounded lower end portion as long as it has a conical shape as a whole. The long protrusion group 16 includes a pair of long protrusion rows 20 and 21, and the short protrusion group 18 includes a pair of short protrusion rows 22 and 23. The long protrusion rows 20 and 21 and the short protrusion rows 22 and 23 are provided so as to extend in the left-right direction. The long protrusion rows 20 and 21 and the short protrusion rows 22 and 23 are provided in parallel to each other. The short protrusion row 22 is provided behind the long protrusion row 20. The short protrusion row 23 is provided in front of the long protrusion row 21. That is, the short protrusion rows 22 and 23 are provided at positions closer to the suction port 14 than the long protrusion rows 20 and 21. Further, the distance between the long protrusions 15 constituting the long protrusion rows 20 and 21 is equal to the distance between the short protrusions 17 constituting the short protrusion rows 22 and 23. The short projections 17 are located between the long projections 15 in a front view as shown in FIG. That is, the long protrusions 15 and the short protrusions 17 are arranged in a staggered manner.

次に、本実施形態の作用について説明する。前記掃除機本体２に前記ノズル３及び集塵手段４が取り付けられた状態で、前記電源コード９の先端に設けられた図示しない電源プラグを、同じく図示しない電源に接続した後、同じく図示しないスイッチ操作部を操作することで、前記電動送風機５が作動する。そして、このように前記電動送風機５が作動することで、前記ノズル３から図示しない吸引経路、前記集塵手段４を経て前記電動送風機５に至る吸引気流が形成される。この吸引気流に含まれる塵埃は、前記集塵手段４内で吸引気流から分離され、前記集塵手段４内に溜められる。 Next, the operation of this embodiment will be described. In the state where the nozzle 3 and the dust collecting means 4 are attached to the cleaner body 2, a power plug (not shown) provided at the tip of the power cord 9 is connected to a power source (not shown) and then a switch (not shown). The electric blower 5 operates by operating the operation unit. Then, by operating the electric blower 5 in this manner, a suction air flow from the nozzle 3 to the electric blower 5 through the suction path (not shown) and the dust collecting means 4 is formed. Dust contained in the suction airflow is separated from the suction airflow in the dust collection means 4 and stored in the dust collection means 4.

被清掃物が毛足の長い絨毯Ｃである場合、この絨毯Ｃ上に前記ノズル３を押し当てると、図４に示すように、前記各長突起１５は撓んだ状態で前記絨毯Ｃの深層部に到達する。一方、前記各短突起１７は、殆ど撓まずに、その先端部が前記絨毯Ｃの表層部に接触する。このような状態で、前記絨毯Ｃに沿って矢印Ａ方向に前記ノズル３を動かすと、前記各長突起１５は、前記絨毯Ｃの全層に亘って前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出すと共に、前記各短突起１７は、前記絨毯Ｃの表層部において前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出す。そして、この梳き出された抜け毛等は、前記各突起１５，１７同士の間隙から、吸引気流と共に前記吸込口１４に流入し、前記集塵手段４にて吸引気流から分離される。なお、前記各長突起１５は、前述したように、撓んだ状態で前記絨毯Ｃの毛を梳くので、この絨毯Ｃを傷めにくくすることができる。一方、前記各短突起１７は、殆ど撓まないものの、前記絨毯Ｃの表層部に軽く接し、この表層部のみを梳く。このため、前記各短突起１７は、前記絨毯Ｃを傷めにくい。また、前記各短突起１７が前記絨毯Ｃを梳く際の抵抗は、前記各長突起１５が前記絨毯Ｃを梳く際の抵抗よりも小さくすることができる。また、前記短突起１７は、その先端部が前記絨毯Ｃの表層部に接するので、その先端部によって前記絨毯Ｃの表層部を効果的に梳くことができる。このため、本実施形態の前記ノズル３は、本実施形態の長突起１５の数と短突起１７の数の和と同数の長突起を設けた構造に比べ、比較的小さな力で絨毯Ｃを梳いて、良好に清掃することができる。 When the object to be cleaned is a carpet C having long hairs, when the nozzle 3 is pressed onto the carpet C, as shown in FIG. 4, the long protrusions 15 are bent and the deep layer of the carpet C is bent. Reach the department. On the other hand, the respective short protrusions 17 are hardly bent and their tip portions come into contact with the surface layer portion of the carpet C. In this state, when the nozzle 3 is moved in the direction of arrow A along the carpet C, the long protrusions 15 enter between the hairs of the carpet C over the entire layer of the carpet C. While scooping out hair loss and the like, each short protrusion 17 enters between the hairs of the carpet C in the surface layer portion of the carpet C and scoops out hair loss and the like. Then, the hair fallen out and the like flows into the suction port 14 together with the suction airflow from the gap between the protrusions 15 and 17, and is separated from the suction airflow by the dust collecting means 4. In addition, since each said long protrusion 15 combs the hair of the said carpet C in the bent state as mentioned above, this carpet C can be made hard to be damaged. On the other hand, although each said short protrusion 17 hardly bends, it touches the surface layer part of the said carpet C lightly, and only this surface layer part is combed. For this reason, each said short protrusion 17 cannot damage the said carpet C easily. Further, the resistance when each of the short protrusions 17 combs the carpet C can be made smaller than the resistance when each of the long protrusions 15 combs the carpet C. Moreover, since the front-end | tip part contact | connects the surface layer part of the said carpet C, the surface part of the said carpet C can be effectively wound with the front-end | tip part. For this reason, the nozzle 3 of the present embodiment folds the carpet C with a relatively small force as compared with the structure in which the number of long projections 15 is the same as the sum of the number of long projections 15 and the number of short projections 17 of the present embodiment. And can be cleaned well.

なお、前記絨毯Ｃの毛足が短い場合、前記短突起１７は前記絨毯Ｃに触れない可能性がある。この場合、前記長突起１５のみによって、前記絨毯Ｃに付着した抜け毛等が梳き出される。しかしながら、毛足の短い前記絨毯Ｃは、毛足の長いものよりも抜け毛等が梳き出され易い。従って、毛足の短い前記絨毯Ｃの場合、前記長突起１５のみであっても、抜け毛等を良好に梳き出すことができる。 In addition, when the hair feet of the carpet C are short, the short protrusions 17 may not touch the carpet C. In this case, only the long projections 15 cause hair loss and the like attached to the carpet C to be rolled out. However, the carpet C with short hairs is more susceptible to hair loss than those with long hairs. Therefore, in the case of the carpet C with short hairs, even with only the long protrusions 15, hair loss and the like can be favorably sprinkled.

被清掃物がふとん等である場合、このふとん等の上に前記ノズル３を押し当てると、図５に示すように、負圧によってふとん等の表面の布Ｆが前記吸込口１４に吸引される。しかしながら、前記各突起１５，１７によって、前記ノズル３の底面１３と布Ｆとの間に隙間が確保されると共に、前記長突起列２０と短突起列２２との間及び前記長突起列２１と短突起列２３との間にも隙間が確保されるので、前記吸込口１４を塞ぐことなく、所定量の吸引気流を確保することができる。このように、所定量の吸引気流が確保された状態で、前記ふとん等の表面の布Ｆに沿って矢印Ａ方向に前記ノズル３を動かすと、前記各長突起１５は、撓みながら前記布Ｆの表面に付着した抜け毛等を掻き集める。一方、前記各短突起１７は、前記布Ｆが吸引されることで、その先端部が前記布Ｆと接するため、前記各長突起１５よりも軽く前記布Ｆと接し、前記布Ｆに付着した抜け毛等を掻き集める。そして、この掻き集められた抜け毛等は、前記各突起１５，１７同士の間隙から、吸引気流と共に前記吸込口１４に流入し、前記集塵手段４にて吸引気流から分離される。なお、前記各長突起１５は、前述したように、撓んだ状態で前記ふとん等の表面の布Ｆに接するので、この布Ｆを傷めにくくすることができる。一方、前記各短突起１７は、殆ど撓まないものの、前述したように、前記ふとん等の表面の布Ｆに対し軽く接するので、この布Ｆを傷めにくくすることができる。 When the object to be cleaned is a futon or the like, when the nozzle 3 is pressed onto the futon or the like, the cloth F on the surface of the futon or the like is sucked into the suction port 14 by negative pressure as shown in FIG. . However, the projections 15 and 17 ensure a gap between the bottom surface 13 of the nozzle 3 and the cloth F, and between the long projection row 20 and the short projection row 22 and the long projection row 21. Since a gap is also secured between the short protrusion rows 23, a predetermined amount of suction airflow can be secured without blocking the suction port 14. Thus, when the nozzle 3 is moved in the direction of arrow A along the cloth F on the surface of the futon or the like in a state where a predetermined amount of suction airflow is secured, the long protrusions 15 are bent while the cloth F Scrape off hair loss from the surface of the skin. On the other hand, each short protrusion 17 is in contact with the cloth F lighter than each long protrusion 15 and adheres to the cloth F because the tip of the short protrusion 17 is in contact with the cloth F when the cloth F is sucked. Scrape hair loss. Then, the scraped hairs and the like collected from the gaps between the protrusions 15 and 17 flow into the suction port 14 together with the suction airflow, and are separated from the suction airflow by the dust collecting means 4. In addition, since each said long protrusion 15 contacts the cloth F of the surface of the said futon etc. in the bent state as mentioned above, this cloth F can be made hard to be damaged. On the other hand, although each said short protrusion 17 hardly bends, as mentioned above, since it touches lightly with respect to the cloth F of the surface of the said futon etc., this cloth F can be made hard to be damaged.

なお、人や動物の抜け毛等は、梳き出されたり掻き集められたりした際に、前記各突起群１６，１８に絡み付く可能性がある。しかしながら、前述した通り、前記各突起１５，１７が先細の円錐形に形成されるので、前記各突起群１６，１８に絡んだ抜け毛等が、前記ノズル３の動きに伴って、前記各突起１５，１７の傾斜に沿って抜けるので、前記各突起群１６，１８に抜け毛等が絡み付かないようにすることができる。 It should be noted that hair loss of humans and animals may be entangled with each of the projection groups 16 and 18 when the hair is scraped or scraped. However, as described above, since the projections 15 and 17 are formed in a tapered conical shape, the hairs and the like entangled with the projection groups 16 and 18 may be caused by the movement of the nozzle 3. , 17 can be removed along the inclination of the projections 16, 18 so that no hairs fall off the projection groups 16, 18.

以上のように本発明は、吸込口１４を有するノズル本体１１と、このノズル本体１１の吸込口１４の近傍に設けられる突起群とを有する電気掃除機１のノズル３において、可撓性を有する材質で前記突起群を構成すると共に、前記突起群を、複数の長突起１５からなる長突起群１６と、複数の短突起１７からなる短突起群１８とで構成したことで、前記長突起群１６が撓みながら絨毯Ｃ等の深層部の抜け毛等を梳き出し、前記短突起群１８が撓みながら絨毯Ｃ等の表層部の抜け毛等を梳き出すことで、絨毯Ｃ等を傷めることなく、効果的に絨毯Ｃ等に付着した抜け毛等を掻き集めることができるばかりでなく、前記短突起群１８が絨毯Ｃ等の表層部を擦るように梳くことで、前記短突起群１８と絨毯Ｃ等との抵抗を小さくすることができるので、突起数を多くしながらも、比較的軽い力で絨毯Ｃ等から抜け毛等を良好に梳き出すことができるものである。 As described above, the present invention has flexibility in the nozzle 3 of the vacuum cleaner 1 having the nozzle body 11 having the suction port 14 and the projection group provided in the vicinity of the suction port 14 of the nozzle body 11. The projection group is formed of a material, and the projection group is configured by a long projection group 16 including a plurality of long projections 15 and a short projection group 18 including a plurality of short projections 17. Effectively, without damaging the carpet C or the like, the hair 16 of the deep layer of the carpet C or the like is combed while the 16 is bent, and the hair of the surface layer of the carpet C or the like is curled while the short projection group 18 is bent. In addition to scraping hairs adhering to the carpet C etc., the short projection group 18 can be rubbed against the surface layer of the carpet C, etc., so that the short projection group 18 and the carpet C etc. Can reduce the resistance , While increasing the number of projections, in which can be out combing good hair loss, etc. at a relatively small force from the carpet C and the like.

また、前記各突起群１６，１８を構成する各突起１５，１７を錐状としたことにより、前記各突起群１６，１８に絡んだ抜け毛等が、前記ノズル３の動きに伴って、前記各突起１５，１７の傾斜に沿って抜けるので、前記各突起群１６，１８に抜け毛等が絡み付かないようにすることができるものである。 Further, since the projections 15 and 17 constituting the projection groups 16 and 18 are formed in a cone shape, hair loss and the like entangled with the projection groups 16 and 18 can be caused by the movement of the nozzle 3. Since the protrusions 15 and 17 come out along the inclination, it is possible to prevent the hairs and the like from getting tangled in the protrusion groups 16 and 18.

次に、本発明の第二の実施形態について、図７乃至図１０に基づいて説明する。なお、本実施形態では、ノズル３０のみについて説明し、掃除機本体２及び集塵手段４については説明を省略する。また、前記ノズル３０についても、第一の実施形態と共通する部分については共通の符号を付し、その説明を省略する。 Next, a second embodiment of the present invention will be described with reference to FIGS.

次に、本実施形態の作用について説明する。被清掃物が毛足の長い絨毯Ｃである場合、この絨毯Ｃ上に前記ノズル３０を押し当てると、図９に示すように、前記各長突起３１は撓んだ状態で前記絨毯Ｃの深層部に到達する。一方、前記各短突起３３は、殆ど撓まずに、その先端部が前記絨毯Ｃの表層部に接触する。このような状態で、前記絨毯Ｃに沿って矢印Ａ方向に前記ノズル３０を動かすと、前記各長突起３１は、前記絨毯Ｃの全層に亘って前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出すと共に、前記各短突起３３は、前記絨毯Ｃの表層部において前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出す。そして、この梳き出された抜け毛等は、前記各突起３１，３３同士の間隙から、吸引気流と共に前記吸込口１４に流入し、集塵手段４にて吸引気流から分離される。なお、前記各長突起３１は、前述したように、撓んだ状態で前記絨毯Ｃの毛を梳くので、この絨毯Ｃを傷めにくくすることができる。一方、前記各短突起３３は、殆ど撓まないものの、前記絨毯Ｃの表層部に軽く接し、この表層部のみを梳くので、前記絨毯Ｃを傷めにくくすることができるばかりでなく、前記各短突起３３が前記絨毯Ｃを梳く際の抵抗を小さくすることができる。また、前記短突起３３は、その先端部が前記絨毯Ｃの表層部に接するので、その先端部によって前記絨毯Ｃの表層部を効果的に梳くことができる。このため、本実施形態の前記ノズル３０は、本実施形態の長突起３１の数と短突起３３の数の和と同数の長突起を設けた構造に比べ、比較的小さな力で絨毯Ｃを梳いて、良好に清掃することができる。 Next, the operation of this embodiment will be described. When the object to be cleaned is a carpet C having a long bristle, when the nozzle 30 is pressed onto the carpet C, as shown in FIG. Reach the department. On the other hand, each short protrusion 33 hardly bends and its tip part comes into contact with the surface layer part of the carpet C. In such a state, when the nozzle 30 is moved in the direction of arrow A along the carpet C, the long protrusions 31 enter between the hairs of the carpet C over the entire layer of the carpet C. While scooping out hair loss and the like, each short protrusion 33 enters between the hairs of the carpet C in the surface layer portion of the carpet C and scoops out hair loss and the like. Then, the hair fallen out and the like flows into the suction port 14 together with the suction airflow from the gap between the protrusions 31 and 33 and is separated from the suction airflow by the dust collecting means 4. In addition, since each said long protrusion 31 combs the hair of the said carpet C in the bent state as mentioned above, this carpet C can be made hard to be damaged. On the other hand, although each said short protrusion 33 hardly bends, since it touches the surface layer part of the said carpet C lightly and only this surface layer part is rolled, not only can it make the said carpet C hard to be damaged, The resistance when the protrusion 33 combs the carpet C can be reduced. Moreover, since the front-end | tip part contact | connects the surface layer part of the said carpet C, the said surface part of the said carpet C can be effectively wound with the front-end | tip part. For this reason, the nozzle 30 of the present embodiment folds the carpet C with a relatively small force compared to the structure in which the number of long protrusions 31 and the number of short protrusions 33 in the present embodiment are the same as the sum of the long protrusions. And can be cleaned well.

なお、前記絨毯Ｃの毛足が短い場合、前記短突起３３は前記絨毯Ｃに触れない可能性がある。この場合、前記長突起３１のみによって、前記絨毯Ｃに付着した抜け毛等が梳き出される。しかしながら、毛足の短い前記絨毯Ｃは、毛足の長いものよりも抜け毛等が梳き出され易い。従って、毛足の短い前記絨毯Ｃの場合、前記長突起３１のみであっても、抜け毛等を良好に梳き出すことができる。 In addition, when the hair feet of the carpet C are short, the short protrusion 33 may not touch the carpet C. In this case, only the long protrusions 31 shed hairs and the like attached to the carpet C. However, the carpet C with short hairs is more susceptible to hair loss than those with long hairs. Therefore, in the case of the carpet C with short hairs, even with only the long protrusions 31, hair loss and the like can be favorably sprinkled.

被清掃物がふとん等である場合、このふとん等の上に前記ノズル３０を押し当てると、図１０に示すように、負圧によってふとん等の表面の布Ｆが前記吸込口１４に吸引される。しかしながら、前記各突起３１，３３によって、前記ノズル３０の底面１３と布Ｆとの間に隙間が確保されるので、前記吸込口１４を塞ぐことなく、所定量の吸引気流を確保することができる。このように、所定量の吸引気流が確保された状態で、前記ふとん等の表面の布Ｆに沿って矢印Ａ方向に前記ノズル３０を動かすと、前記各長突起３１は、撓みながら前記布Ｆの表面に付着した抜け毛等を掻き集める。一方、前記各短突起３３は、前記布Ｆが吸引されることで、その先端部が前記布Ｆと接した場合、前記各長突起３１よりも軽く前記布Ｆと接し、前記布Ｆに付着した抜け毛等を掻き集める。そして、この掻き集められた抜け毛等は、前記各突起３１，３３同士の間隙から、吸引気流と共に前記吸込口１４に流入し、前記集塵手段４にて吸引気流から分離される。なお、前記各長突起３１は、前述したように、撓んだ状態で前記ふとん等の表面の布Ｆに接するので、この布Ｆを傷めにくくすることができる。一方、前記各短突起３３は、殆ど撓まないものの、前述したように、前記ふとん等の表面の布Ｆに対し軽く接するので、この布Ｆを傷めにくくすることができる。 When the object to be cleaned is a futon or the like, when the nozzle 30 is pressed onto the futon or the like, the cloth F on the surface of the futon or the like is sucked into the suction port 14 by negative pressure as shown in FIG. . However, since the gaps are secured between the bottom surface 13 of the nozzle 30 and the cloth F by the projections 31 and 33, a predetermined amount of suction airflow can be secured without blocking the suction port 14. . Thus, when the nozzle 30 is moved in the direction of arrow A along the cloth F on the surface of the futon or the like in a state where a predetermined amount of suction airflow is secured, the long protrusions 31 are bent while the cloth F Scrape off hair loss from the surface of the skin. On the other hand, when each of the short protrusions 33 is attracted to the cloth F, when the tip of the short protrusion 33 comes into contact with the cloth F, the short protrusion 33 comes into contact with the cloth F lighter than the long protrusions 31 and adheres to the cloth F. Scrap off the lost hair. The scraped hairs and the like flow into the suction port 14 together with the suction airflow from the gap between the protrusions 31 and 33 and are separated from the suction airflow by the dust collecting means 4. In addition, since each said long protrusion 31 contacts the cloth F of the surface of the said futon etc. in the bent state as mentioned above, this cloth F can be made hard to be damaged. On the other hand, although each said short protrusion 33 hardly bends, as mentioned above, since it touches lightly with respect to the cloth F of the surface of the said futon etc., this cloth F can be made hard to be damaged.

なお、人や動物の抜け毛等は、梳き出されたり掻き集められたりした際に、前記各突起群３２，３４に絡み付く可能性がある。しかしながら、前述した通り、前記各突起３１，３３が先細の円錐形に形成されるので、前記各突起群３２，３４に絡んだ抜け毛等が、前記ノズル３０の動きに伴って、前記各突起３１，３３の傾斜に沿って抜けるので、前記各突起群３２，３４に抜け毛等が絡み付かないようにすることができる。 It should be noted that hair loss or the like of humans or animals may be entangled with the projection groups 32 and 34 when they are scooped out or scraped. However, as described above, since each of the protrusions 31 and 33 is formed in a tapered conical shape, hair loss or the like entangled with each of the protrusion groups 32 and 34 is caused by the movement of the nozzle 30. , 33 is removed along the slope of the projections 33, so that the protruding groups 32, 34 can be prevented from getting entangled with hair loss or the like.

以上のように本発明は、吸込口１４を有するノズル本体１１と、このノズル本体１１の吸込口１４の近傍に設けられる突起群とを有する電気掃除機１のノズル３０において、可撓性を有する材質で前記突起群を構成すると共に、前記突起群を、複数の長突起３１からなる長突起群３２と、複数の短突起３３からなる短突起群３４とで構成したことで、前記長突起群３２が撓みながら絨毯Ｃ等の深層部の抜け毛等を梳き出し、前記短突起群３４が撓みながら絨毯Ｃ等の表層部の抜け毛等を梳き出すことで、絨毯Ｃ等を傷めることなく、効果的に絨毯Ｃ等に付着した抜け毛等を掻き集めることができるばかりでなく、前記短突起群３４が絨毯Ｃ等の表層部を擦るように梳くことで、前記短突起群３４と絨毯Ｃ等との抵抗を小さくすることができるので、突起数を多くしながらも、比較的軽い力で絨毯Ｃ等から抜け毛等を良好に梳き出すことができるものである。 As described above, the present invention has flexibility in the nozzle 30 of the vacuum cleaner 1 having the nozzle body 11 having the suction port 14 and the projection group provided in the vicinity of the suction port 14 of the nozzle body 11. The projection group is formed of a material, and the projection group is configured by a long projection group 32 including a plurality of long projections 31 and a short projection group 34 including a plurality of short projections 33, thereby the long projection group. It is effective without damaging the carpet C and the like by scooping out the hair loss of the deep layer portion such as the carpet C while 32 is bent, and scooping out the hair loss of the surface layer portion such as the carpet C while the short projection group 34 is bent. In addition to scraping off hairs adhering to the carpet C etc., the short projection group 34 can be rubbed against the surface layer portion of the carpet C etc., so that the short projection group 34 and the carpet C etc. The resistance can be reduced In, while increasing the number of projections, in which can be out combing good hair loss, etc. at a relatively small force from the carpet C and the like.

また、前記各突起群３２，３４を構成する各突起３１，３３を錐状としたことにより、前記各突起群３２，３４に絡んだ抜け毛等が、前記ノズル３０の動きに伴って、前記各突起３１，３３の傾斜に沿って抜けるので、前記各突起群３２，３４に抜け毛等が絡み付かないようにすることができるものである。 Further, since the projections 31 and 33 constituting the projection groups 32 and 34 are formed in a cone shape, hair loss and the like entangled with the projection groups 32 and 34 are caused by the movement of the nozzle 30. Since the protrusions 31 and 33 come out along the inclination, it is possible to prevent the hairs and the like from getting tangled in the protrusion groups 32 and 34.

次に、本実施形態の作用について説明する。被清掃物が毛足の長い絨毯Ｃである場合、この絨毯Ｃ上に前記ノズル５０を押し当てると、図１４に示すように、前記各長突起５１は撓んだ状態で前記絨毯Ｃの深層部に到達する。これに対し、前記各第一短突起５３は、殆ど撓まずに、その先端部が前記絨毯Ｃの中層部に達する。また、前記各第二短突起５５は、殆ど撓まずに、その先端部が前記絨毯Ｃの表層部に接触する。このような状態で、前記絨毯Ｃに沿って矢印Ａ方向に前記ノズル５０を動かすと、前記各長突起５１は、前記絨毯Ｃの全層に亘って前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出す。また、前記各第一短突起５３は、前記絨毯の表層部から中層部に亘って前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出す。更に、前記各第二短突起５５は、前記絨毯Ｃの表層部において前記絨毯Ｃの毛の間に入り込んで、抜け毛等を梳き出す。そして、この梳き出された抜け毛等は、前記各突起５１，５３，５５同士の間隙から、吸引気流と共に前記吸込口１４に流入し、集塵手段４にて吸引気流から分離される。なお、前記各長突起５１は、前述したように、撓んだ状態で前記絨毯Ｃの毛を梳くので、この絨毯Ｃを傷めにくくすることができる。前記各第一短突起５３も、前記絨毯Ｃの毛との抵抗によって僅かに撓みながら前記絨毯Ｃの毛を梳くので、この絨毯Ｃを傷めにくくすることができる。一方、前記各第二短突起５５は、殆ど撓まないものの、前記絨毯Ｃの表層部に軽く接し、この表層部のみを梳くので、前記絨毯Ｃを傷めにくくすることができる。そして、前記第一短突起５３は、前記絨毯Ｃの中層部までしか届かないので、前記第一短突起５３が前記絨毯Ｃから受ける抵抗は、前記長突起５１が前記絨毯Ｃから受ける抵抗よりも小さい。また、前記第二短突起５５は、前記絨毯Ｃの表層部までしか届かないので、前記第二短突起５５が前記絨毯Ｃから受ける抵抗は、前記長突起５１や第一短突起５３が前記絨毯Ｃから受ける抵抗よりも小さい。また、前記第二短突起５５は、その先端部が前記絨毯Ｃの表層部に接するので、その先端部によって前記絨毯Ｃの表層部を効果的に梳くことができる。このため、本実施形態の前記ノズル５０は、本実施形態の長突起５１の数と第一短突起５３の数と第二短突起５５の数の和と同数の長突起を設けた構造に比べ、比較的小さな力で絨毯Ｃを梳いて、良好に清掃することができる。 Next, the operation of this embodiment will be described. When the object to be cleaned is a carpet C having a long bristle, when the nozzle 50 is pressed onto the carpet C, as shown in FIG. 14, the long protrusions 51 are bent and the deep layer of the carpet C is bent. Reach the department. On the other hand, the first short protrusions 53 reach the middle layer of the carpet C without being bent. Further, the second short protrusions 55 are hardly bent and the tip portions thereof contact the surface layer portion of the carpet C. In such a state, when the nozzle 50 is moved in the direction of arrow A along the carpet C, the long protrusions 51 enter between the hairs of the carpet C over the entire layer of the carpet C. Scrape out hair loss. Each of the first short protrusions 53 enters between the hairs of the carpet C from the surface layer portion to the middle layer portion of the carpet, and scoops out hair loss. Furthermore, each said 2nd short processus | protrusion 55 enters between the hairs of the said carpet C in the surface layer part of the said carpet C, and combs out hair loss etc. Then, the hair fallen out and the like flow into the suction port 14 together with the suction airflow from the gaps between the protrusions 51, 53, 55, and are separated from the suction airflow by the dust collecting means 4. In addition, since each said long protrusion 51 combs the hair of the said carpet C in the bent state as mentioned above, this carpet C can be made hard to be damaged. Since each said 1st short processus | protrusion 53 also combs the hair of the said carpet C, bending slightly by resistance with the hair of the said carpet C, it can make this carpet C hard to be damaged. On the other hand, although each said 2nd short protrusion 55 hardly bends, since it contacts the surface layer part of the said carpet C lightly and only this surface layer part is rolled, the said carpet C can be made hard to be damaged. Since the first short protrusion 53 reaches only the middle layer of the carpet C, the resistance that the first short protrusion 53 receives from the carpet C is greater than the resistance that the long protrusion 51 receives from the carpet C. small. Further, since the second short protrusion 55 reaches only the surface layer portion of the carpet C, the resistance received by the second short protrusion 55 from the carpet C is that the long protrusion 51 and the first short protrusion 53 are the carpet. Less than the resistance received from C. Moreover, since the front-end | tip part of the said 2nd short processus | protrusion 55 touches the surface layer part of the said carpet C, the surface-layer part of the said carpet C can be effectively wound with the front-end | tip part. For this reason, the nozzle 50 of this embodiment has a structure in which the number of long protrusions 51, the number of first short protrusions 53, and the number of second short protrusions 55 are the same as the number of long protrusions 51 in this embodiment. It is possible to clean the carpet C with a relatively small force and clean it well.

なお、前記絨毯Ｃの毛足がやや短い場合、前記第二短突起５５は前記絨毯Ｃに触れない可能性がある。この場合、図１５に示すように、前記長突起５１及び第一短突起５３のみによって、前記絨毯Ｃに付着した抜け毛等が梳き出される。そしてこの場合、前記第一短突起５３の先端は、前記絨毯Ｃの表層部までしか届かない。しかしながら、毛足のやや短い前記絨毯Ｃは、毛足の長いものよりも抜け毛等が梳き出され易い。従って、毛足のやや短い前記絨毯Ｃの場合、前記長突起５１と第一短突起５３のみであっても、抜け毛等を良好に梳き出すことができる。即ち、この場合、前記第一短突起５３が前述した第一の実施形態における前記短突起１７の代わりとなることで、第一の実施形態の場合と同様に作用する。また、前記絨毯Ｃの毛足が短い場合、前記第一短突起５３も前記絨毯Ｃに触れない可能性がある。この場合、前記長突起５１のみによって、前記絨毯Ｃに付着した抜け毛等が梳き出される。しかしながら、毛足の短い前記絨毯Ｃは、毛足の長いものや毛足のやや短いものよりも抜け毛等が梳き出され易い。従って、毛足の短い前記絨毯Ｃの場合、前記長突起５１のみであっても、抜け毛を良好に梳き出すことができる。 In addition, when the hair feet of the carpet C are slightly short, the second short protrusion 55 may not touch the carpet C. In this case, as shown in FIG. 15, only the long protrusions 51 and the first short protrusions 53 shed hairs and the like attached to the carpet C. In this case, the tip of the first short protrusion 53 reaches only the surface layer portion of the carpet C. However, the carpet C, which has a slightly short hair, is more susceptible to hair loss than a long hair. Therefore, in the case of the carpet C having a slightly short hair, even with only the long protrusions 51 and the first short protrusions 53, hair loss and the like can be favorably sprinkled. That is, in this case, the first short protrusion 53 replaces the short protrusion 17 in the first embodiment described above, and thus acts in the same manner as in the first embodiment. Further, when the hair of the carpet C is short, the first short protrusion 53 may not touch the carpet C. In this case, only the long protrusions 51 cause hair loss and the like attached to the carpet C to be rolled out. However, the carpet C having short hairs is more susceptible to hair loss than those having long hairs or slightly short hairs. Therefore, in the case of the carpet C with short hairs, even with only the long projections 51, hair loss can be favorably sprinkled.

被清掃物がふとん等である場合、このふとん等の上に前記ノズル５０を押し当てると、図１６に示すように、負圧によってふとん等の表面の布Ｆが前記吸込口１４に吸引される。しかしながら、前記各突起５１，５３，５５によって、前記ノズル５０の底面１３と布Ｆとの間に隙間が確保されると共に、前記長突起列５８と第一短突起列６０との間、この第一短突起列６０と第二短突起列６２との間、前記第二短突起列６３と第一短突起列６１との間、及びこの第一短突起列６１と長突起列５９との間にも隙間が確保されるので、前記吸込口１４を塞ぐことなく、所定量の吸引気流を確保することができる。このように、所定量の吸引気流が確保された状態で、前記ふとん等の表面の布Ｆに沿って矢印Ａ方向に前記ノズル５０を動かすと、前記各長突起５１は、撓みながら前記布Ｆの表面に付着した抜け毛等を掻き集める。一方、前記第一短突起５３及び各第二短突起５５は、前記布Ｆが吸引されることで、その先端部が前記布Ｆと接するため、前記各長突起５１よりも軽く前記布Ｆと接し、前記布Ｆに付着した抜け毛等を掻き集める。そして、この掻き集められた抜け毛等は、前記各突起５１，５３，５５同士の間隙から、吸引気流と共に前記吸込口１４に流入し、集塵手段４にて吸引気流から分離される。なお、前記各長突起５１は、前述したように、撓んだ状態で前記ふとん等の表面の布Ｆに接するので、この布Ｆを傷めにくくすることができる。一方、前記各第一短突起５３及び第二短突起５５は、殆ど撓まないものの、前述したように、前記ふとん等の表面の布Ｆに対し軽く接するので、この布Ｆを傷めにくくすることができる。 When the object to be cleaned is a futon or the like, when the nozzle 50 is pressed onto the futon or the like, the cloth F on the surface of the futon or the like is sucked into the suction port 14 by negative pressure as shown in FIG. . However, a gap is secured between the bottom surface 13 of the nozzle 50 and the cloth F by the projections 51, 53, and 55, and between the long projection row 58 and the first short projection row 60. Between the first short protrusion row 60 and the second short protrusion row 62, between the second short protrusion row 63 and the first short protrusion row 61, and between the first short protrusion row 61 and the long protrusion row 59. In addition, since a gap is secured, a predetermined amount of suction airflow can be secured without blocking the suction port 14. Thus, when the nozzle 50 is moved in the direction of arrow A along the cloth F on the surface of the futon or the like in a state where a predetermined amount of suction airflow is secured, the long protrusions 51 are bent while the cloth F Scrape off hair loss from the surface of the skin. On the other hand, the first short protrusions 53 and the second short protrusions 55 are lighter than the long protrusions 51 because the tips of the first short protrusions 53 and the second short protrusions 55 are in contact with the cloth F. Touch and scrape hairs and the like adhering to the cloth F. Then, the scraped hairs and the like flow into the suction port 14 together with the suction airflow from the gaps between the protrusions 51, 53, 55, and are separated from the suction airflow by the dust collecting means 4. In addition, since each said long protrusion 51 contacts the cloth F of the surface of the said futon etc. in the bent state as mentioned above, this cloth F can be made hard to be damaged. On the other hand, although the first short protrusions 53 and the second short protrusions 55 hardly bend, as described above, the first short protrusions 53 and the second short protrusions 55 are lightly in contact with the cloth F on the surface of the futon or the like. Can do.

なお、人や動物の抜け毛等は、梳き出されたり掻き集められたりした際に、前記各突起群５２，５４，５６に絡み付く可能性がある。しかしながら、前述した通り、前記各突起５１，５３，５５が先細の円錐形に形成されるので、前記各突起群５２，５４，５６に絡んだ抜け毛等が、前記ノズル５０の動きに伴って、前記各突起５１，５３，５５の傾斜に沿って抜けるので、前記各突起群５２，５４，５６に抜け毛等が絡み付かないようにすることができる。 It should be noted that hair loss of humans and animals may be entangled with the projection groups 52, 54, and 56 when they are scooped out or scraped. However, as described above, the protrusions 51, 53, and 55 are formed in a tapered conical shape, so that hair loss and the like entangled with the protrusion groups 52, 54, and 56 are caused by the movement of the nozzle 50. Since the protrusions 51, 53, and 55 are pulled out along the slopes, the protruding groups 52, 54, and 56 can be prevented from getting entangled with hair.

以上のように本発明は、吸込口１４を有するノズル本体１１と、このノズル本体１１の吸込口１４の近傍に設けられる突起群とを有する電気掃除機１のノズル５０において、可撓性を有する材質で前記突起群を構成すると共に、前記突起群を、複数の長突起５１からなる長突起群５２と、複数の第一短突起５３からなる第一短突起群５４及び複数の第二短突起５５からなる第二短突起群５６とで構成したことで、前記長突起群５２が撓みながら絨毯Ｃ等の深層部の抜け毛等を梳き出し、前記第一短突起群５４が撓みながら絨毯Ｃ等の中層部の抜け毛等を梳き出し、前記第二短突起群５６が撓みながら絨毯Ｃ等の表層部の抜け毛等を梳き出すことで、絨毯Ｃ等を傷めることなく、効果的に絨毯Ｃ等に付着した抜け毛等を掻き集めることができるばかりでなく、前記第一短突起群５４が絨毯Ｃ等の中層部から表層部にかけて梳くと共に前記第二短突起群５６が絨毯Ｃ等の表層部を擦るように梳くことで、前記各短突起群５４，５６と絨毯Ｃ等との抵抗を小さくすることができるので、突起数を多くしながらも、比較的軽い力で絨毯Ｃ等から抜け毛等を良好に梳き出すことができるものである。 As described above, the present invention has flexibility in the nozzle 50 of the vacuum cleaner 1 having the nozzle body 11 having the suction port 14 and the projection group provided in the vicinity of the suction port 14 of the nozzle body 11. The protrusion group is made of a material, and the protrusion group is divided into a long protrusion group 52 including a plurality of long protrusions 51, a first short protrusion group 54 including a plurality of first short protrusions 53, and a plurality of second short protrusions. Since the second short projection group 56 is composed of the second short projection group 56, the long projection group 52 curls out the hair loss of the deep layer portion of the carpet C and the like, and the first short projection group 54 is bent and the carpet C and the like are bent. The hair loss of the middle layer of the carpet C and the second short projection group 56 are flexed and the hair loss of the surface layer of the carpet C and the like is sprinkled, so that the carpet C and the like are effectively damaged without being damaged. Can scrape hair loss In addition, the first short protrusion group 54 crawls from the middle layer portion to the surface layer portion of the carpet C or the like, and the second short protrusion group 56 rubs the surface layer portion of the carpet C or the like so that each short protrusion Since the resistance between the groups 54 and 56 and the carpet C and the like can be reduced, hair loss and the like can be favorably sprinkled from the carpet C and the like with a relatively light force while increasing the number of protrusions.

また、前記各突起群５２，５４，５６を構成する各突起５１，５３，５５を錐状としたことにより、前記各突起群５２，５４，５６に絡んだ抜け毛等が、前記ノズル５０の動きに伴って、前記各突起５１，５３，５５の傾斜に沿って抜けるので、前記各突起群５２，５４，５６に抜け毛等が絡み付かないようにすることができるものである。 Further, since the projections 51, 53, 55 constituting the projection groups 52, 54, 56 are formed in a cone shape, hairs entangled with the projection groups 52, 54, 56 cause movement of the nozzle 50. As a result, the protrusions 51, 53, and 55 are pulled out along the inclinations, so that the protruding groups 52, 54, and 56 can be prevented from getting entangled with hair.

なお、本発明は以上の実施形態に限定されるものではなく、発明の要旨の範囲内で種々の変形実施が可能である。例えば、上述した第一及び第三の実施形態では、吸込口から離れた位置の突起列ほど突起の長さが長くなるように構成したが、突起列の位置とその突起列を構成する突起の長さの関係は任意である。また、第二の実施形態では、長突起と短突起とを交互に並べた突起列を、それぞれ吸込口の前後に一列ずつ設けたが、そのような突起列をそれぞれ吸込口の前後に複数列設けても良い。また、第三の実施形態では、短突起群を二種類の長さの短突起によって構成したが、短突起群を三種類以上の長さの短突起によって構成しても良い。更に、長突起と第一短突起とを交互に並べた突起列と、第一短突起と第二短突起とを交互に並べた突起列とを並べて設けるようにしても良い。 In addition, this invention is not limited to the above embodiment, A various deformation | transformation implementation is possible within the range of the summary of invention.
