WASHING MACHINE AND WASHING-DRYING MACHINE

PROBLEM TO BE SOLVED: To provide a washing machine or a washing and drying machine in which erroneous start of a power supply circuit due to induced voltage generating from a motor, is prevented irrespective of the characteristics of a power supply IC.SOLUTION: The washing machine and the washing-drying machine are provided each of which comprises a washing tub for washing laundry and a motor 19 for rotating the washing tub. Each of the washing machine and the washing-drying machine further comprises: a smoothing circuit 52 for smoothing a commercial power supply 51; an inverter circuit 54 for receiving a direct current voltage from the smoothing circuit 52 and supplying the voltage to the motor 19; a control circuit for 57 for controlling the operation of the washing machine and the washing-drying machine and the inverter circuit 54; a power supply circuit 55 for outputting a power supply voltage of the control circuit 57 by using the commercial power supply 51; and a separating circuit 53 for connecting and separating the inverter circuit 54 and the power supply circuit 55 to and from each other. Since an induced voltage of the motor 19 is not applied to the power supply circuit 55, erroneous start of the power supply circuit 55 can be suppressed.SELECTED DRAWING: Figure 4 【課題】電源ＩＣの特性に関係なく，モータから発生する誘起電圧で電源回路が誤起動することのない洗濯機または洗濯乾燥機を提供する。【解決手段】洗濯物を洗うための洗濯槽と、前記洗濯槽を回転させるためのモータ１９を備えた洗濯機および洗濯乾燥機において，商用電源５１を平滑させる平滑回路５２と，平滑回路５２からの直流電圧を受けモータ１９への供給を行なうインバータ回路５４と、洗濯機および洗濯乾燥機の運転とインバータ回路５４を制御する制御回路５７と、商用電源５１を用いて制御回路５７の電源電圧を出力する電源回路５５と、インバータ回路５４と電源回路５５を接続及び分離する分離回路５３とを備え、モータ１９の誘起電圧が電源回路５５に印加されないので、電源回路５５が誤起動することを抑制できる。【選択図】図４
