摘要： PROBLEM TO BE SOLVED: To provide a compact drum type washing machine which generates less vibration and less noise.
SOLUTION: The drum type washing machine comprises a water tub 3 supported at least inside a washing machine case 1 by a spring and a damper 7, a rotatable washing tub 4 installed inside the water tub 3 for storing laundry, and a motor 5 for driving and rotating the washing tub 4. The damper 7 has characteristics of switching to a greater damping force only when the water tub 3 moves upward by the magnitude of vibration of the water tub 3 so as to suppress excessive vibration. In the case of small vibration, the damping force is decreased so as to decrease transmission of the vibration.

摘要： PROBLEM TO BE SOLVED: To provide a compact, low-vibration, and low-noise drum washing machine.
SOLUTION: A damper for supporting a water tub in a washing machine casing from below includes: a cylinder; oil in a space provided in the cylinder; a piston which is provided at the end of a rod, moves in the cylinder where the oil is sealed in and has a plurality of small holes; a flange provided at the rod and leaving a downward distance with respect to the piston; and a valve movable between the piston and the flange. The piston has at least one hole to pass the oil even if the valve contacts the piston and a notch provided in the radial direction and at the lower part of the piston and at the position of the hole. When the damper extends/contracts a length larger than a predetermined length by the vibration of the water tub in a resonance range during dehydration, damping characteristics are switched so that the damping force increases only when the water tub is moving upward.

摘要： PROBLEM TO BE SOLVED: To reduce impact sound and impact force generated from a hanging bar by providing buffering materials in a part which is fitted to the hanging bar in order to reduce impact sound in a vibration resistance mechanism constituted of a slider member, the hanging bar, a mobile body having a sliding member and a cylindrical body. SOLUTION: The vibration resistance spring 2c of the vibration resistance mechanism receives a load so as to be in adhesive state by throwing clothes and washing water, etc., into a spinning tub at the time of washing. Then, vibrating rotation occurs in an outer basin by the rotation of a stirring blade, the hanging bar 2b is freely moved in a gap among the fitting parts of the slider member 2a, the cylindrical body 2i and a spring receiver 2f, but it is hit against the inner wall surfaces of the respective fitting parts when a vibration becomes more than the gap. Then, the buffering materials 2k, 2l and 2m having cushion property such as rubber, etc., are provided in the fitting parts so as to absorb hitting sound or impact force at the time of a collision and to prevent transmission to the outer basin or an outer frame. Besides, the vibration occurs by the deviation of clothes, etc., as a cause at the time of dehydration, but the sound and impact force at the time of the collision are absorbed in the same way as that at the time of washing.

摘要： PROBLEM TO BE SOLVED: To prevent the rigidity of a mounting plate from becoming anisotropic so as to reduce the vibrations of an inner tank that will follow an elliptic orbit produced by the anisotropy by forming the shape of a mounting plate, which supports an inner tank and a driving means of driving stirring blades and is fixed to an outer tank bottom, into an approximate circle. SOLUTION: This washing machine with a spin-dryer has an outer tank 3 of a synthetic resin resiliently supported by an outer frame 1 through suspension rods 2 and an inner tank 5 housed in the outer tank 3. The inner tank 5 has stirring blades 4 at the central part of the bottom of the inner tank 5 and the upper opening part of the inner tank 5 is provided with a fluid balancer 12 for canceling the unbalance. The inner tank 5 is supported by a clutch shaft 14 through a flange 6 and a clutch 7 supporting the flange 6 and a motor 8 are supported by a mounting plate 9 on the outer tank 3. The mounting plate 9 is formed into an approximate circle so that the entire of the bottom of the outer tank may be covered and is also formed to have symmetrical bending properties for the central clutch shaft 14.
