Title:
WASHING MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/027811
Kind Code:
A1
Abstract:
A washing machine, comprising: an ultrasonic cleaning device (50); a constant load spring, which applies an elastic force to the ultrasonic cleaning device (50) to move the ultrasonic cleaning device to a drawn-out position; a damper (530), which applies a braking force to the ultrasonic cleaning device (50) moving to the drawn-out position due to the elastic force; and a shaking prevention portion (480), which clamps the rear end of the ultrasonic cleaning device (50) in a vertical direction, so as to prevent the ultrasonic cleaning device (50) from shaking in the vertical direction at the drawn-out position. Clamping of the rear end of the ultrasonic cleaning device (50) by the shake prevention portion (480) starts from the position just before the ultrasonic cleaning device (50) reaches the drawn-out position. The damper (530) stops applying the braking force to the ultrasonic cleaning device (50) before the ultrasonic cleaning device (50) reaches the clamping start position at which the shake prevention portion (480) starts clamping. The washing machine can easily draw out the ultrasonic cleaning device from an accommodating portion.
