Description
【考案の詳細な説明】
本考案は洗濯物を攪拌して洗浄する攪拌翼をモータの回
転子に直結、もしくは洗濯時のみ適当な減速機構を介し
て直結した攪拌式洗濯機に関するもので、洗濯時と脱水
時における必要トルクに応じて、モータの巻線仕様を切
替えて、消費電力およびモータの発熱の低減を図ること
を目的とする。[Detailed description of the invention] The present invention relates to an agitating washing machine in which the agitating blades for agitating and washing the laundry are directly connected to the rotor of a motor, or directly connected through an appropriate speed reduction mechanism only during washing. The purpose is to reduce power consumption and motor heat generation by switching the motor winding specifications depending on the time and torque required during dehydration.
攪拌式洗濯機においては、モータの一定方向の回転運動
をギアで減速し、ラック、ピニオン等により回転運動を
往復回転運動に変換しているが、生産コストが高く、騒
音を発生すると共に摩耗や機械的故障の原因となったり
して、信頼性の点で必らずしも十分でながった。In agitator-type washing machines, the rotary motion of the motor in a fixed direction is decelerated by gears, and the rotary motion is converted into reciprocating rotary motion using racks, pinions, etc., but this method is expensive to produce, generates noise, and causes wear and tear. This has not always been sufficient in terms of reliability, as it may cause mechanical failures.
また、攪拌翼の往復回転運動をモータの回転子の往復回
転運動により行うモータ直結型のこの種洗濯機において
、洗濯時に高トルクを必要とするが、脱水時の高速回転
時には、トルクは激減するため、モータの回転数が高く
なりすぎ、振動や騒音の発生防止のために、回転数の制
御を必要とした。In addition, this type of washing machine that is directly connected to a motor, in which the reciprocating rotation of the stirring blades is performed by the reciprocating rotation of the motor's rotor, requires high torque during washing, but the torque decreases dramatically during high-speed rotation during spin-drying. As a result, the motor rotation speed became too high, making it necessary to control the rotation speed to prevent vibration and noise.
本考案は上記した従来の問題点を解決すべく威されたも

コンデンサ14,14 aはモータ6の起動および運転
用のコンテ゛ンサを示している。Capacitors 14 and 14a represent capacitors for starting and operating the motor 6.
次に具体的な動作を説明すると、洗濯時においては、第
4図に示す如く、負荷のトルク特性Aは低速回転で高ト
ルクを必要とするため、モータ6も特性aの如く高トル
クを要する。Next, to explain the specific operation, during washing, as shown in FIG. 4, the torque characteristic A of the load requires high torque at low speed rotation, so the motor 6 also requires high torque as shown in characteristic a. .
したがって、第2図に示した様に、主巻線、補助巻線の
それぞれにおいて、第1巻線9,10と第2巻線9a、
10aを並列に接続して、巻数を少なくして線径を増し

切替えてモータ6の正逆運転を行うことにより、攪拌翼
4を往復回転させて洗濯を行う。With such a connection, the switch 12 is switched at regular intervals to operate the motor 6 in forward and reverse directions, thereby causing the stirring blades 4 to reciprocate and perform washing.

くなりすぎ、振動騒音が大きくなってしまう。During dehydration, as shown in Figure 4, the torque characteristic B of the load is high speed rotation, and the torque is lower than during washing, so if the motor is operated with the same wire connections as during washing, The rotational speed of the motor that drives the inner tank becomes too high, resulting in increased vibration and noise.
したがって、第3図に示したような結線状態に、脱水初
期から切替えるが、脱水の立上り回転を早めるために脱
水開始後において切替える。Therefore, the connection state as shown in FIG. 3 is changed from the initial stage of dehydration, but is changed after the start of dehydration in order to hasten the start-up rotation of dehydration.
