  • Publication number: 20180057986
    Abstract: The present disclosure provides a washing machine, including a washing and dewatering drum for accommodating washings, and a water injection port portion arranged above the washing and dewatering drum and connected with a faucet. Herein, the water injection port portion includes a water flowing path through which water from the faucet flows, a wall portion arranged at a front end of the water flowing path to intercept the flowing water, and a plurality of outflow hole portions arranged on a bottom surface of the water flowing path along the wall portion so that the water flowing through the water flowing path flows into the washing and dewatering drum; and the plurality of outflow hole portions allow the water to flow out in such a manner that water from each outflow hole portion does not contact with each other.

  • Publication number: 20180016732
    Abstract: Provided is a washing machine which can reduce number of parts for a structure for absorbing water and draining water into a washing tank. The washing machine (1) includes: an outer tank (3) capable of storing water; a washing tank (5) contained in the outer tank (3), having a through hole (23) for allowing water to flow between the washing tank (5) and the outer tank (3) and used for containing washings and rotatable; water paths (4) for absorbing water stored in the outer tank (3); an exhaust port (11) for draining water absorbed through the water paths (4) into the washing tank (5) from above Z1; and blades (40) integrally arranged on a bottom wall (21) of the washing tank (5) to deliver water stored in the outer tank (3) into the water paths (4) by rotating with the washing tank (5) integrally.

  • Publication number: 20170327994
    Abstract: The present disclosure provides a washing machine capable of sprinkling water on washings contained in a washing tank without dead angle. The washing machine includes an outer tank capable of storing water, a cylindrical washing tank contained in the outer tank, used for containing the washings and capable of rotating, and a water path for absorbing water stored in the outer tank and discharging the water into the washing tank from an upper side. The washing tank is provided with through holes for allowing water to flow between the washing tank and the outer tank. Discharging ports for discharging water into the washing tank from the upper side through the water path are arranged around whole area of the circumferential direction S of the washing tank.

  • Patent number: 5973284
    Abstract: A push-button switch for use in electronic devices is provided which reduces stress on contact parts. A C-shaped elastic member is secured at one end to a bottom wall of a switch casing and engages a movable member at its other end. The movable member in turn pivotably engages a contact member having movable elastic arms which abut non-conducting inclined surfaces on the bottom wall of the casing when the switch is open. To close the switch, a knob disposed slidably within the casing is depressed, bringing a bottom surface of the knob into engagement with an end of the movable member and deforming the C-shaped elastic member by bringing its ends closer together. Further, the contact member is caused to pivot about the movable member and move toward the bottom wall of the casing. Consequently, the movable elastic arms of the contact member slide off the inclined surfaces and into electrical contact with stationary contacts in the bottom wall of the switch casing to form a conductive path.

  • Patent number: 5077588
    Abstract: A multiple wavelength light emitting device having a single p-n junction and at least two light emitting layers within a diffusion region of a minority carrier comprises a p-type Ga.sub.1-x1 Al.sub.x1 As layer, a p-type Ga.sub.1-x2 Al.sub.x2 As layer, a p-type Ga.sub.1-x3 Al.sub.x3 As layer, and an n-type Ga.sub.1-y Al.sub.y As layer, where x.sub.1, x.sub.2, x.sub.3 and Y represent aluminum arsenide mixed crystal ratios of the respective layers. The light emitting alyers, i.e., the p-type Ga.sub.1-x2 Al.sub.x2 As layer and the p-type Ga.sub.1-x3 Al.sub.x3 As layer each have a different band gap to emit an infrared light and a visible light, respectively. Since the infrared and ivsible lights are simultaneously emitted, emission of the infrared light can be confirmed or monitored by the visible light. The light emitting device of the present invention utilizes an energy well for trapping electrons and an energy barrier for preventing electrons from diffusing to improve the whole light emitting efficiency.
