Embodiment approach

[0023] figure 1 It is a vertical cross-sectional view showing the structure of a drum-type washing and drying machine according to an embodiment of the present invention. exist figure 1 Among them, the water tank 52 with the rotating drum 53 freely rotatable is elastically anti-vibration supported on the main body of the laundry, that is, the inside of the housing 51, by elastic support mechanisms such as springs 64 and shock absorbers 58. Washing tank for washing.

[0024] The rotary drum 53 is rotationally driven in combination with a motor 54 , a drive unit fixed to the right outer wall of the water tank 52 . The laundry is agitated and washed by hammer washing in which the laundry is picked up by a plurality of agitation projections 62 formed on the inner wall of the rotary drum 53 and then dropped. The motor 54 for rotationally driving the rotating drum 53 is constituted by a brushless motor or the like, has a variable rotation speed, and repeats normal rotation and ...

Abstract

A drum-type washing machine is disclosed, and during a step of peeling the laundry off rotary drum (53), controller (57) of the washing machine compares a magnitude of vibrations sensed by acceleration sensor (56) and corresponding to a rotary cycle of rotary drum (53) with another magnitude of vibrations sensed by acceleration sensor (56) and corresponding to another rotary cycle of drum (53), so that the controller (57) determines whether or not the laundry is peeled off the inner wall of drum (53). This structure allows sensing accurately the vibration of water tub (52) and also sensing more properly the status whether or not the laundry in drum (53) is peeled off.

Description

technical field [0001] The present invention relates to a drum type washing machine, which installs a bottomed cylindrical rotating drum in a water tank, and washes the laundry stored in the rotating drum by rotating and driving the rotating drum. Background technique [0002] Conventionally, such a drum-type washing machine having a drying function (hereinafter referred to as a drum-type washing and drying machine) rotates a rotary drum at a high speed in a dehydration step to dehydrate laundry by centrifugal force. Therefore, the laundry is attached to the side of the rotary drum. When the laundry is attached to the side of the rotary drum and enters the drying step, since the contact area between the drying air and the laundry is limited, the drying step ends in an undried state. [0003] Therefore, in order to release the laundry from sticking to the side of the rotating drum, for example, Japanese Patent Application Laid-Open No. 2000-254385 (Patent Document 1) propose...
