Embodiment Construction
[0016] figure 1 It is a cross-sectional view of front-loading-type washing machine 1 according to the embodiment of the present invention. The washing machine 1 includes a housing 6 and a sink unit 7 accommodated in the housing 6 . Water tank unit 7 has water tank 3 , rotary drum 2 accommodated in water tank 3 , bearing 68 fixed to water tank 3 , and motor 5 fixed to water tank 3 . The motor 5 is connected to the rotary drum 2 via the rotary shaft portion 2B, and rotates the rotary drum 2 around the rotary axis 2A. The rotating shaft portion 2B is supported by a bearing 68 . Rotary drum 2 has side wall 2E having a cylindrical shape extending centering on rotation axis 2A, and bottom 2F, which is provided facing motor 5 and connected to rotation shaft 2B. Many holes 2G are formed in the side wall 2E. Rotary drum 2 has opening 2C facing forward of casing 6 and positioned on rotation axis 2A on the side opposite to bottom 2F. Water tank 3 has opening 3C facing forward of ho...

A drum type washing machine includes a housing, a washtub unit (7) accommodated in the housing, a damper for elastically supporting the washtub at a supporting position, a vibration sensor for detecting a vibration of the washtub. The washtub unit includes a washtub having an opening therein, a rotary drum accommodated in the washtub, and a motor fixed to a bottom of the washtub and joined to a bottom of the rotary drum for rotating the rotary drum about a rotary axis. The rotary drum is adapted to accommodate a laundry. The supporting position and a center of gravity of the washtub unit approximate to the motor from a center plane which passes a center of the washtub and which is perpendicular to the rotary axis. The supporting position is distanced farther from the motor along a horizontal direction than the center of gravity is. The vibration sensor outputs a first signal and a second signal corresponding to a component of vibration of a portion of the washtub along a first direction and a component of the vibration along a second direction perpendicular to the first direction, respectively.
Description
technical field [0001] The invention relates to a front-loading washing machine with a rotary drum rotating about a horizontal or inclined axis of rotation. Background technique [0002] Figure 7 It is a cross-sectional view of a conventional front-loading washing machine 501 . The front-loading washing machine 501 includes a housing 506 with an inlet and outlet, a water tank 503 elastically supported in the housing 506 by a vibration-proof shock absorber 570, a motor 505 fixed to the back side of the water tank 503, and a rotating drum arranged in the water tank 503. 502 , a door 509 provided on the housing 506 and provided at the entrance, and an elastic sealing member 541 provided at the entrance of the housing 506 . The water tank 503 , the rotary drum 502 and the motor 505 constitute a water tank unit 507 . Many holes are formed on the rotary drum 502 . The opening of the water tank 503 communicates with the inlet and outlet of the casing 506 . Rotary drum 502 has ...
