  • Patent number: 10168694
    Abstract: Provided is a heat source device including a control unit which, in response to a predetermined request for heating, sets a switching valve to a first circulation mode to communicate first and third ports, whereas to cut off communication between second and third ports, and performs a heating operation by actuating a burner and a circulation pump. In response to a predetermined request for hot water supply, the control unit sets the switching valve to a second circulation mode to communicate second and third ports, whereas to cut off communication between first and third ports, and performs a hot water supply operation, by actuating the burner and the circulation pump. A hot water supply stop alarm unit issues a hot water supply stop alarm that urges a user to stop using hot water when the request for heating is continued for a first predetermined time or more.

  • Patent number: 9057186
    Abstract: This integrally formed water and space saving lavatory-toilet fixture enables hand washing with potable water from an existing toilet, recycles effluent completely, and provides sanitary, seamless, one-piece, full perimeter tank closure. A flexible hose re-directs supply away from the overflow through an interior fixture cavity and top cast opening toward a basin, that drains back into the reservoir as effluent; supplementing the required volume of water to complete one flush cycle. A cast sidewall basin opening is formed allowing potential drainage to flow through an internal hollow cavity directly into the tank reservoir below. The integrally formed fixture also includes a sloped front wall allowing additional hand washing space, vertically aligned space saving side and rear walls, and, an integrally formed perimeter rim conforming to the shape of the toilet tank edging below, providing hygienic, continuous tank containment and secure, detachable mounting.

  • Patent number: 5393228
    Abstract: A dental prophylaxis and water conservation device for in-home use. The device includes a tank coupled to the household water supply line and adapted to receive water which causes air contained within the tank to be pressurized. The water and air from within the tank are connected by lines to a handpiece which discharges both mediums simultaneously. Water leaving the tank passes through a container having an abrasive material which is picked up by the water and also discharged. The tank is further coupled to a plumbing fixture, such as a shower head. This enables the tank to be used as a water conservation device by allowing cold water to be purged from a hot water line into the tank, and subsequently used to provide water to the plumbing fixture. To recycle the purged water, the present invention entrains the water from within the tank as water from the supply line is being provided to the plumbing fixture.

  • Patent number: 5287570
    Abstract: A control system for water faucets comprises an on-off control switch located at a sink and actuated by pressure applied and released by the body of the user. When the body of the user pushes forward towards the sink, the switch will be depressed and the water faucets will turn on. When the user backs away from the sink, the switch will be released and close off the flow of water. An overflow reservoir is provided to collect cold water run off prior to the time when hot water makes its way through the water pipes, and a temperature sensor switch and/or alarm controls either an automatic or manual change over from hot to cold water. In addition, a microprocessor and key board control various water delivery functions such as volume and temperature. The control system reduces leakage and saves water which would otherwise be lost due to running the hot water until it becomes heated to the desired temperature.
