【０００２】[0002]
【従来の技術】従来より一般的な洗濯機として、渦巻式
のものが撹拌式のものが知られている。渦巻式のもの
は、洗濯槽の底部に撹拌翼を設け、この回転によって、
渦巻水流を発生させ衣類を反転させながら洗濯するもの
であり、撹拌翼の回転数は３００rpm 以上と高速であ

布のからみが布の片寄りも大きいものであった。2. Description of the Related Art Conventionally, as a general washing machine, a spiral type and a stirring type are known. The spiral type is equipped with a stirring blade at the bottom of the washing tub, and by this rotation,
This is for washing clothes by generating a swirling water flow and reversing the clothes. The rotation speed of the stirring blade is as high as 300 rpm or more, and the outer diameter of the stirring blade is about 1 / the inner diameter of the washing tub.
It is set as small as 2 or less. For this reason, the difference in the cleaning power between the portion where the stirring blade directly contacts the clothes and the other portion has a large difference in the damage to the cloth. Furthermore, when transmitting the rotating force of the stirring blade to the upper clothes, a large twist of the cloth occurs,
The entanglement of the cloth was large even at one side of the cloth.
【０００３】これらの問題点を改良するものとして、特

の比０.５ 〜１）し、回転数を２８０rpm 以下に設定す
るとともに撹拌翼の正逆の反転同期をこきざみに制御
（０.５ 秒〜５秒）するものである。As a means for improving these problems, there is one described in JP-A-58-149787. This is also called a large-diameter blade spiral type, and the stirring blade has a larger diameter (ratio of 0.5 to 1 with the washing tub), the rotation speed is set to 280 rpm or less, and the stirring blade is reverse-synchronized. The speed is controlled in every step (0.5 to 5 seconds).
【０００４】撹拌式のものは、撹拌翼の中央に規定水位
よりも高い円筒を有するものであり、短周期で正逆転を
行ない、１回当たりの回転数を約２〜３回転以下に設定
し、振り洗いするものである。The stirring type has a cylinder higher than the specified water level in the center of the stirring blade, and performs normal and reverse rotation in a short cycle, and the number of rotations per rotation is set to about 2 to 3 rotations or less. , Shake it.
【０００５】[0005]
【発明が解決しようとする課題】撹拌式の場合、撹拌翼
の中央に円筒を設け、振り洗いをする方式であるため、
布のからみ，布の傷みは少ない反面、布に与える機械力
は、渦巻式に対し小さい。また、この方式は、布の上下
の入れ替えは少ないので、容量が増えてくること上方の
衣類は動きずらくなる。In the case of the stirring type, since a cylinder is provided in the center of the stirring blade and shaking is performed,
Although there is little entanglement or damage to the cloth, the mechanical force applied to the cloth is smaller than that of the spiral type. Further, in this method, since the upper and lower parts of the cloth are not exchanged with each other, the capacity of the cloth is increased, so that the clothes on the upper side become difficult to move.
【０００６】これに対し、渦巻式は、洗浄力や衣類の動
きは良いが、布のからみや布の片寄りが大きい。布の片
寄りは、全自動洗濯機の場合、脱水時のアンバランスと
なり、脱水起動成功率が低下したり、振動・騒音が大き
くなり好ましくない。大径羽根渦巻式のものも、布の傷
みや，洗いむらは改善できるものの布のからみは同等で
あり、布の片寄りも少ないとはいえないものであった。On the other hand, in the spiral type, the cleaning power and the movement of clothes are good, but the entanglement of the cloth and the deviation of the cloth are large. In the case of a fully automatic washing machine, the unevenness of the cloth causes an imbalance during dehydration, which reduces the success rate of dehydration start-up and causes large vibration and noise, which is not preferable. The large-diameter spiral-wound type was also able to improve the damage and washing unevenness of the cloth, but the cloth had the same entanglement, and the deviation of the cloth was not so small.
【０００７】本発明の目的は、布の上下の入れ替えを増
大させ、洗浄力を向上させるとともに布からみや布の片
寄りも従来の渦巻式より低減できる洗濯機用撹拌翼を有
する全自動洗濯機を提供することにある。An object of the present invention is to provide a fully automatic washing machine having a stirring blade for a washing machine, which can increase the upside down replacement of the cloth, improve the cleaning power, and reduce the cloth entanglement and the deviation of the cloth from the conventional spiral type. To provide.

【課題を解決するための手段】撹拌翼の中央部に円筒部
を設け、筒状で、その外表面に外方へ突出するリブを有
する振動子を円筒部の上端部に回転可能に取り付ける。A cylindrical portion is provided at the center of a stirring blade, and a vibrator having a cylindrical shape and a rib protruding outward on its outer surface is rotatably attached to the upper end portion of the cylindrical portion.
【０００９】また、上下方向に所定の間隔を保ち、下方
に面する上波形面および、上方に面する下波形面を振動
子に形成するとともに、前記各波形面にて挾持される複
数個の突部を前記円筒部に形成する。Further, an upper corrugated surface facing downward and a lower corrugated surface facing upward are formed on the vibrator while keeping a predetermined interval in the vertical direction, and a plurality of corrugated surfaces sandwiched between the corrugated surfaces are formed. A protrusion is formed on the cylindrical portion.

【００１１】[0011]
【作用】洗濯撹拌時の布の上下の入れ替わりは、次のメ
カニズムによるものである。[Function] The upper and lower parts of the cloth are agitated when the laundry is stirred by the following mechanism.
【００１２】撹拌翼が正転から逆転に切替わる時、撹拌

じれが発生、外周部の布が、中央部に引き寄せられる。
引き寄せられた布は、中央部から上方に押し上げられ、
布の上下の入り替わりを行なわれる。When the stirring blade is switched from normal rotation to reverse rotation, a difference occurs in peripheral speed between the cloth on the outer peripheral portion of the stirring blade and the cloth on the central portion, causing a slight twist, and the cloth on the outer peripheral portion is pulled toward the central portion. To be
The pulled cloth is pushed upward from the center,
The top and bottom of the cloth are swapped.
【００１３】このとき、前述した、振動子の上下動が布

となる。If the height of the cylindrical portion at the center of the stirring blade is close to the prescribed water level, the cloth will be difficult to entangle and the cloth will not move easily, although the deviation of the cloth is small. On the contrary, if the height of the cylinder is low, the cloth moves better,
The deviation of the cloth increases. Therefore, it is effective to provide a cylindrical portion having a predetermined height and promote the replacement of the cloth by the vibrator.
