Description

洗濯機Washing machine
　本発明は、洗濯兼脱水槽の内底部に配設された攪拌翼によって、洗濯物を洗う洗濯機に関する。 This invention relates to the washing machine which wash | cleans laundry with the stirring blade arrange | positioned in the inner bottom part of the washing and dewatering tank.
　従来、この種の洗濯機において、攪拌翼により回転水流を発生させて、洗濯物を効率的に洗う構成が提案されている（例えば、特許文献１参照）。 Conventionally, in this type of washing machine, a configuration has been proposed in which a rotating water flow is generated by a stirring blade to efficiently wash laundry (for example, see Patent Document 1).
　図６は、特許文献１に記載された従来の洗濯機の攪拌翼の外観を示す斜視図である。 FIG. 6 is a perspective view showing an appearance of a stirring blade of a conventional washing machine described in Patent Document 1. FIG.
　図６において、洗濯兼脱水槽の内底部に回転自在に配設された、円盤状の攪拌翼７０の表面は、周縁部７０ａに対して中心に行くほど深くなる盆状（椀状）に形成されている。攪拌翼７０の表面には、放射状に配される４つの羽根部７１が、突出して形成されている。また、羽根部７１に対して周方向に隣接する凹部７２が設けられている。 In FIG. 6, the surface of the disc-shaped stirring blade 70 rotatably disposed on the inner bottom portion of the washing and dewatering tub is formed in a basin shape (a bowl shape) that becomes deeper toward the center with respect to the peripheral portion 70a. Has been. On the surface of the stirring blade 70, four blade portions 71 arranged in a radial manner are formed so as to protrude. Further, a recess 72 adjacent to the blade portion 71 in the circumferential direction is provided.
　羽根部７１の上面には、攪拌翼７０の径方向に延びる複数のリブ７３ａが、周方向に並設されている。外周側のリブ７３ａの間隔は、内周側における間隔よりも狭く形成されている。また、凹部７２の上面には、攪拌翼７０の周方向に延びる複数のリブ７３ｂが、径方向に並設されている。リブ７３ｂは、回転中心を中心とする円弧に対して湾曲しており、羽根部７１に近い位置では回転中心からの距離が小さく、羽根部７１から離れた位置で回転中心からの距離が大きくなるように構成されている。羽根部７１に近い位置のリブ７３ｂの間隔は、羽根部７１から離れた位置での間隔よりも狭くなるように形成されている。 A plurality of ribs 73 a extending in the radial direction of the stirring blade 70 are juxtaposed in the circumferential direction on the upper surface of the blade portion 71. The interval between the outer peripheral ribs 73a is narrower than the interval on the inner peripheral side. A plurality of ribs 73 b extending in the circumferential direction of the stirring blade 70 are juxtaposed in the radial direction on the upper surface of the recess 72. The rib 73b is curved with respect to an arc centered on the rotation center, and the distance from the rotation center is small at a position close to the blade part 71, and the distance from the rotation center is large at a position away from the blade part 71. It is configured as follows. The interval between the ribs 73b at a position close to the blade portion 71 is formed to be narrower than the interval at a position away from the blade portion 71.
　以上のような構成によって、洗濯物の攪拌時に、流体の攪拌翼７０表面に対する作用を均質化して、消費電力を抑えつつ、洗浄効果を上げることができる。 With the configuration as described above, when the laundry is stirred, the action of the fluid on the surface of the stirring blade 70 can be homogenized, and the cleaning effect can be improved while suppressing power consumption.
　しかしながら、上述した従来の構成では、攪拌翼７０は、一体成形された樹脂により構成されている。このため、洗濯物が多い場合、または洗濯水の水温が高い場合等には、洗濯物および洗濯水の重量により攪拌翼７０が変形して、攪拌翼７０の底面と洗濯兼脱水槽との隙間が狭くなり、変形が著しい場合には、攪拌翼７０の底面と洗濯兼脱水槽とが接触し、攪拌翼７０および洗濯兼脱水槽のうち少なくともいずれかが破損する虞があるという課題がある。 However, in the conventional configuration described above, the stirring blade 70 is formed of an integrally molded resin. For this reason, when there is a lot of laundry, or when the temperature of the washing water is high, the stirring blade 70 is deformed by the weight of the laundry and the washing water, and the gap between the bottom surface of the stirring blade 70 and the washing and dewatering tub Is narrow and the deformation is significant, there is a problem that the bottom surface of the stirring blade 70 and the washing / dehydrating tank are in contact with each other, and at least one of the stirring blade 70 and the washing / dehydrating tank may be damaged.

　使用者が、洗濯兼脱水槽１５に洗濯物および洗剤を投入した後、操作表示部４３にて運転コースを選択し、スタートスイッチをオン（ＯＮ）する。そうすると、制御部は、給水弁４１を開き、洗濯兼脱水槽１５に給水が行われる。そして、所定の水位まで給水されると、給水は停止され、モータ２０が回転し、その動力が洗濯・脱水軸１４を経由して、攪拌翼１８に伝達され、洗い工程が始まる。 After the user puts laundry and detergent into the washing and dewatering tank 15, the user selects an operation course on the operation display unit 43 and turns on the start switch. Then, the control unit opens the water supply valve 41 and water is supplied to the washing and dewatering tank 15. Then, when the water is supplied to a predetermined water level, the water supply is stopped, the motor 20 is rotated, and the power is transmitted to the stirring blade 18 via the washing / dehydrating shaft 14 to start the washing process.
　このとき、攪拌翼１８には、洗濯物および洗濯水の重量が印加されており、特に、水流形成リブ２８と補助リブ２９との間の部分には、突設された形状がないので、強度的に弱い部分となる。しかしながら、本実施の形態の攪拌翼１８は、その部分に、複数の凸部４０が突設されたステンレス材の薄板からなるプレート３１がインサート成形されているので、強度的に優れており、変形等が生じることはない。 At this time, the weight of the laundry and the washing water is applied to the stirring blade 18, and in particular, the portion between the water flow forming rib 28 and the auxiliary rib 29 does not have a protruding shape. It becomes a weak part. However, the stirring blade 18 of the present embodiment is excellent in strength because the plate 31 made of a stainless steel thin plate with a plurality of protrusions 40 protruding from the portion is insert-molded. Etc. will not occur.
　攪拌翼１８が、正回転および逆回転すると、水流形成リブ２８および補助リブ２９によって、回転水流とともに、洗濯兼脱水槽１５の内壁面に沿った強い上昇水流が発生する。また、プレート３１の六角錘状の凸部４０により、水流形成リブ２８および補助リブ２９の間で渦巻水流が発生するとともに、孔部４２からも水流が吹き出し、水流形成リブ２８および補助リブ２９による水流と合わせて、強い水流となって、洗濯物が攪拌されて洗浄が行われる。 When the stirring blade 18 rotates forward and backward, the water flow forming rib 28 and the auxiliary rib 29 generate a strong rising water flow along the inner wall surface of the washing and dewatering tub 15 along with the rotating water flow. Further, the hexagonal pyramid-shaped convex portion 40 of the plate 31 generates a spiral water flow between the water flow forming rib 28 and the auxiliary rib 29, and a water flow blows out from the hole 42, and the water flow forming rib 28 and the auxiliary rib 29 Together with the water flow, it becomes a strong water flow, and the laundry is stirred and washed.
　また、ステンレス材のプレート３１の凸部４０は、六角錘状であるので、日光が反射してきらめくので、デザイン的にも優れている。 Moreover, since the convex part 40 of the stainless steel plate 31 is a hexagonal pyramid shape, sunlight is reflected and glitters, so that the design is excellent.

　以上述べたように、本実施の形態においては、水流形成リブ２８と補助リブ２９との間に、ステンレス材の薄板からなるプレート３１がインサート成形により埋設されて、攪拌翼１８が構成されている。また、プレート３１には、複数の、それぞれが独立した六角錘状の凸部４０が突設し、隣接する凸部４０の間、および、プレート３１の外周側には、それぞれ、複数の貫通する孔部４２が形成されている。このような構成により、強度的にもデザイン性にも優れ、洗浄性能も向上した洗濯機を実現することができる。 As described above, in the present embodiment, the plate 31 made of a thin plate of stainless steel is embedded between the water flow forming rib 28 and the auxiliary rib 29 by insert molding to constitute the stirring blade 18. . The plate 31 is provided with a plurality of independent hexagonal pyramid-shaped convex portions 40 projecting from each other, and between the adjacent convex portions 40 and on the outer peripheral side of the plate 31, respectively. A hole 42 is formed. With such a configuration, it is possible to realize a washing machine that is excellent in strength and design and improved in cleaning performance.
　また、プレート３１は、外周側全周に平坦部４５が形成され、さらに外周側の端部には、下方へ垂れた湾曲部４６が形成されている。そして、その湾曲部４６をインサート成形により攪拌翼１８の樹脂部に埋設させることにより、プレート３１は、攪拌翼１８に強固に固定され、熱の影響を受けて変形したりすることはなく、強度的に優れた構成を実現することができる。 Further, the plate 31 has a flat portion 45 formed on the entire outer periphery side, and further, a curved portion 46 hanging downward is formed on the end portion on the outer periphery side. And by embedding the curved part 46 in the resin part of the stirring blade 18 by insert molding, the plate 31 is firmly fixed to the stirring blade 18 and is not deformed by the influence of heat, and the strength. An excellent structure can be realized.
　以上述べたように、本実施の形態の洗濯機１００は、本体１１と、攪拌翼１８と、中央底部に攪拌翼１８が回転自在に配された洗濯兼脱水槽１５と、本体１１内部に防振支持され、洗濯兼脱水槽１５を回転自在に内包する水槽１３と、攪拌翼１８および洗濯兼脱水槽１５を回転駆動するモータ２０とを備えている。また、攪拌翼１８の上面に、放射状に突設された複数のリブと、複数のリブ間に埋設された、ステンレス材のプレート３１とを備えている。 As described above, the washing machine 100 according to the present embodiment includes the main body 11, the stirring blade 18, the washing / dehydration tank 15 in which the stirring blade 18 is rotatably disposed at the center bottom portion, and the inside of the main body 11.
