Title
(EN) VERTICAL TYPE WASHING MACHINE
(JA) 縦型洗濯機
Abstract
(EN)

PROBLEM TO BE SOLVED: To increase the capacity of laundry which can be stored in a drum, without increasing the size of the drum.

SOLUTION: A vertical type washing machine includes: an outer tub arranged inside a housing; a drum constituted so as to rotate around a rotary shaft in the outer tub; an annular container arranged in the drum and for storing rolling bodies; a motor for rotationally driving the drum; and a motor control part for controlling the motor. The motor control part controls the motor so as to perform unbalance dissolving control in which, before starting a dewatering step, after increasing the rotational frequency of the drum until it reaches the target rotational frequency exceeding resonance rotational frequency where lateral resonance occurs, the rotational drive of the drum is stopped.

【課題】ドラムを大型化しないで、ドラム内に収容可能な洗濯物の容量を増加させることを可能とする。
【解決手段】本発明の縦型洗濯機は、筐体の内部に配置された外槽と、外槽内において回転軸周りに回転可能に構成されたドラムと、ドラムに配置され、転動体を収容する環状容器と、ドラムを回転駆動するモータと、モータを制御するモータ制御部とを備え、モータ制御部は、脱水工程を開始する前に、ドラムの回転数をドラムの横共振が発生する共振回転数を超える目標回転数に到達するまでを上昇させた後で、ドラムの回転駆動を停止させるアンバランス解消制御を行うように、モータを制御する。
