  • Patent number: 11148928
    Abstract: The present invention discloses a hot water dispenser comprising a water tank, an expansion chamber, and a Venturi module. The expansion chamber comprises a top shell, a bottom shell connected to the top shell, and a flexible bladder. Wherein, the water tank is connected to a dedicated faucet, the Venturi module is connected to a water source through the faucet, so when the dedicated faucet is closed, the expansion chamber then immediately creates suction and removes a part of the hot water from the water tank and into the expansion chamber to avoid hot water residue dripping from the faucet. In addition, when the water in the water tank is heated to its boiling point, a part of the hot water will be sucked into the expansion chamber to reduce the pressure in the water tank and prevent the hot water from being ejected out of the faucet due to vapour.

    Abstract: A solder bath comprises a solder bath main body containing lead-free solder. A heating member heats the solder and is mounted on outer surfaces of a bottom and sides of the solder bath main body. The heating member contains a thermal diffusion member that is made of stainless steel, a porous heat insulator that is mounted on and attached to the thermal diffusion member, and a heating element that is buried in the porous heat insulator. The heating element is also away from the thermal diffusion member. The thermal diffusion member is heated by heat of the heating element to heat the solder bath main body evenly through thermal diffusion from the thermal diffusion member up to a constant range of temperature and the solder contained in the solder bath is heated evenly to a constant range of temperature.

  • Patent number: 8126320
    Abstract: Methods of determining the likelihood of the existence of a dry fire condition in a hot water heater without requiring energization of any of the heating elements are presented. Such methods utilize only the sensor inputs required for normal operation of the hot water heater. Such sensory inputs are characterized in a process of fuzzification to enable the utilization of fuzzy logic rules to determine the likelihood of a dry fire condition before any energization of a heating element occurs. Alternatively, the sensory inputs are assigned logical values and are processed using Boolean logic to determine if a dry fire condition exists, prior to the energization of any electrical heating element within the hot water heater. Upon the determination that a dry fire condition is likely, the controller may perform a soft or hard lockout, may allow reset(s), and may provide an indication to the user of the condition.

  • Publication number: 20110311209
    Abstract: A method for channeling hot/warm working fluid includes coupling a first fluid supply path in flow communication with an inlet of a first transparent fluid reservoir to a fluid inlet valve, coupling an outlet of the first transparent fluid reservoir in flow communication to a fluid outlet supply path, coupling a second fluid reservoir in flow communication with the first transparent fluid reservoir, and coupling a second fluid supply path in flow communication with an outlet of the second fluid reservoir to a fluid outlet valve. The method also includes directing working fluid of a temperature that is above a minimum threshold temperature from the fluid inlet valve to the fluid outlet supply path through the first transparent fluid reservoir, and directing working fluid of a temperature that is below the minimum threshold temperature from the first transparent fluid reservoir to the fluid outlet valve through the second fluid reservoir.

  • Patent number: 8068727
    Abstract: Methods and systems for evaluating the condition of a water tank having a powered anode protection system. The water heater includes a storage tank to hold water, a powered anode, and a control circuit. The control circuit includes a variable voltage supply, a voltage sensor, and a current sensor. The control circuit is configured to compare a measured parameter to a threshold. In some constructions, the threshold is indicative of a condition of the storage tank at which the powered anode is no longer able to protect the storage tank from corrosion. In other constructions, the threshold is predicative of a potential failure of the storage tank caused by corrosion. In some constructions, the control circuit is configured to estimate a time remaining until the predicted failure of the storage tank.

  • Patent number: 7965929
    Abstract: A heat recovery device particularly for association downstream of devices suitable to heat water. The device is constituted by a tank provided with an inlet for recovering warm water from domestic drains and an outlet for draining toward the sewer. The tank has a set of tubes for water which arrives from the mains and is thus heated before being fed to devices such as a boiler, water heater, et cetera. The device therefore allows savings in water heating for domestic or industrial uses.
