• the operation control of the drum-type washing tub 10 is performed by control signals from the control unit 12, and the operation control is performed by the operation panel 14 so that the device user can adjust the operation control. I have to.
• a characteristic of the present embodiment is that water for rinsing is supplied from a lower position of the drum type washing tub 10.
• the washing water supply / discharge unit 16 is formed so as to be fed into the tub. What is more characteristic is that fine water bubbles are mixed in the supplied washing water 102.
• an air bubble generator 18 is provided, in which air bubbles are mixed and then supplied into the drum washing tub 10.
• this water is supplied by forming a circulation path, and the pump 20, the bubble generator 18, and the washing water supply / discharge section 16 of the drum are connected by a pipeline. It forms a circulation path.
• a button trap 24 is provided in front of the pump 20 so as to be able to capture lost items from the laundry.
• the discharge channel for discharging water is separately formed (reference numeral 22).
• control unit 12 also controls the operation of the pump 20 and the bubble generator 18 in accordance with an instruction from the control panel 14.
