  • Patent number: 10168047
    Abstract: A control unit includes a scale detection unit for detecting, while the a burner provides combustion, occurrence of clogging with scale in a tube of a heat exchanger, and an output unit for outputting a result of a detection by the scale detection unit, a storage stores information including a numerical value representing how many times a surface temperature of the heat exchanger measured by a temperature measuring unit exceeds at least one of a plurality of threshold values. While the burner provides combustion when the surface temperature measured by the temperature measuring unit exceeds at least one of the plurality of threshold values the scale detection unit adds a predetermined value to the numerical value in the storage and when the numerical value attains a defined value or more the scale detection unit detects occurrence of clogging with scale.

  • Patent number: 9810450
    Abstract: A water heater includes a burner generating combustion gas, a heat exchanger heating water which flows through the inside, through heat exchange with combustion gas generated in the burner, a fan supplying air to the burner, and a housing storing these components. The water heater has a water entry portion in a top plate of the housing. A water supply pipe for supplying water to the inside of the heat exchanger is connected to the water entry portion. The water entry portion is arranged to be included, in a plane view, in at least one component constituting the heat exchanger and an exhaust path for combustion gas which has passed through the heat exchanger. The component is made of a material having corrosion resistance against drainage water resulting from condensation of combustion gas.

  • Patent number: 6984075
    Abstract: An optical connector which includes an insertion opening for inserting therein a plug section of an optical fiber cable. There is an optical element which is to be optically connected to the optical fiber cable as inserted in the insertion opening, and a shutter for opening and closing the insertion opening. The shutter is to be mounted to an apparatus and serves as a connector to the apparatus. The shutter is arranged so as to be distinguishable from an optical connector of other type by the color of the shutter which is exposed to the outside when mounting the optical connector to an apparatus.

  • Patent number: 6609384
    Abstract: It is intended to provide a dynamic type ice cold storage method and system capable of efficiently suppressing, by an appropriate replenishment of water, an increase in concentration of an aqueous solution with the progress of freezing of the aqueous solution, thereby preventing a lowering in the coefficient of performance of a refrigerator, and hence diminishing power required for the formation of ice crystals. The temperature of an aqueous solution contained in a freezer which includes a heat exchanger for cooling is measured with a thermometer, and as the liquid temperature drops with the progress of freezing, melted water is replenished into the freezer from a melted water tank by means of a pump to keep almost constant the temperature of freezing performed by the heat exchanger for cooling.
