Abstract: A waterproof cover includes: a lid unit having a vent hole which allows an inner surface and an outer surface to communicate with each other, and configured to cover an electronic component; and a filter fixed to the inner surface of the lid unit in a state of facing an inner open end portion of the vent hole, and configured to block flow of a liquid while allowing air to flow therethrough, in which the outer surface of the lid unit has a surface area including a surface in which an outer open end portion of the vent hole is exposed, and the surface area has a region formed at a position adjacent to the vent hole and having a height different from a height of the surface.

Abstract: An electric pump includes: a pump main body that accommodates a pump unit and a motor; and a plate-shaped elastic member that is wound around an outer circumference of the pump main body such that a longitudinal direction of the elastic member extends along a circumferential direction of the pump main body, in which the elastic member is provided with a pair of first locking portions on both end portions in the longitudinal direction, and the outer circumference of the pump main body is provided with a pair of first locking target portions that are locked to the first locking portions.

Abstract: A machine with vibration source includes a frame for carrying a vibration source such as a motor. A housing is attached to a bottom of the frame, in which a sphere made of a rigid material is housed rotation free in a manner that a portion of the sphere is projected from an opening at the bottom of the housing. The surface of a plate made of a rigid material contacts the portion of the sphere projecting from the housing and the plate is surrounded by a member of an elastic material. The elastic member has an upwardly extending portion which surrounds the housing, and therefore, the elastic member controls the relative position between the sphere and the plate, and resultingly, rolling of the machine can be suppressed. In addition, since the sphere can be rotated on the plate, horizontal vibration of the machine is absorbed to be suppressed. Furthermore, since the sphere is supported by the plate and the plate is supported by a floor via the elastic member, vertical vibration of the machine is also suppressed.

Abstract: A drum-type washing machine includes a horizontal shaft type drum which is rotatably supported by a supporting shaft within a frame and rotated by a motor, and a reduction mechanism transmits a rotation of a rotation shaft of the motor to a rotation shaft of the drum. The reduction mechanism includes a small pulley with gear secured to the rotation shaft of the motor, an intermediate large pulley, a V belt wound on the small pulley with gear and the intermediate large pulley, an intermediate small pulley secured to the intermediate large pulley to be rotated together with the intermediate large pulley, a large pulley secured to the rotation shaft of the drum, and a V belt wound on the intermediate small pulley and the large pulley. In the vicinity of the small pulley with gear, a claw which is normally biased toward a direction that the same is kept away from the gear is arranged. A solenoid or a torque motor engages the claw with a root of the gear against the spring when the drum is to be locked.

Abstract: A drum-type washing machine includes a resin drum which is rotatably supported in a frame by a horizontal shaft. The resin drum includes a body portion molded out of a synthetic resin, and an end surface formed at one end of the body portion, the other end being open. A fluid balancer positioned at the open end of the body portion includes a hollow annular member and a predetermined amount of saltwater sealed therein. The drum diameter is increased from the one end to the other end by utilizing a taper or slope from a plastic molding process. Therefore, the wash in the drum, in operation, moves to the vicinity of the fluid balancer at the other end of the drum along the slope of the inner surface of the drum, thereby to produce a maximum balancing effect of the fluid balancer.

Abstract: A dish washer with dryer comprising a washing and drying compartment defined in a main body wherein tableware to be cleaned and dried are loaded, a washing pump for spraying cleaning water into the compartment, a heater and fan for feeding drying air into the compartment after the spraying of the cleaning water, the dish washer with dryer comprising:a leading inlet and outlet for the drying air located on a compartment wall of the washing and drying room;suction and exhaust holes for outside air located on an outer body wall of the main body wall;a circulating air pathway for connecting the leading inlet with the leading outlet and a cooling air pathway for connecting the suction hole with the exhaust hole between the room wall and the outer body wall;a double faced fan which forms a part of a partition board by which both pathways are partitioned.

Abstract: A washing machine comprises a drum rotating device, a water supplying device, a draining device, a sensing device for sensing excessive foam generated beyond a permissible amount in an outer tub of the washing machine in the washing operation, and a control device for controlling the drum rotating device, the water supplying device and the draining device. In this washing machine, the sensing device would sense the abnormal foaming in the washing operation and inputs a foam sensing signal to the control device. Then, the control device forces the water supplying device to supply water in the tub and/or the draining device to drain the tub so as to settle the abnormal foaming.
