  • Patent number: 10809749
    Abstract: A temperature controller includes a microprocessor, a temperature detector, a current detector, a control relay and an external interface. Wherein, the temperature detector detects a working temperature of a heater; the current detector detects a current value passing through a heating element; and the microprocessor determines an operating state of the temperature controller (102) according to a temperature and a current value received from the temperature detector and the current detector, and sends a control signal to the control replay, thereby controlling the operation of the heater so as to adjust the temperature. By means of the temperature controller, current measurement is added while temperature measurement is performed, so that an operating state of a heater can be correctly determined, thereby greatly improving the reliability of the temperature controller.

    Abstract: The present invention relates to a cord structured to connect a power source to a power take-off. The cord comprises a conductor extending along a length of the cord between opposite ends thereof, an insulator secured in surrounding relation to the conductor and extending along a length thereof, at least one resistance wire connected to the insulator and extending along at least a majority of a length of the insulator, a switching structure connected to the resistance wire and structured to define an active connection of the resistance wire in current receiving relation to the power source, and a temperature sensor structured to sense temperature exteriorly of the insulator. The temperature sensor is connected to the switching structure and is operative therewith to establish the active connection on determination of a predetermined ambient temperature. The resistance wire heats the insulator upon establishment of the active connection.

  • Patent number: 9826858
    Abstract: A hot fluid preparation unit for a fully automatic coffee machine is specified. With the goal of reducing the heating-up time of a fluid, the solution according to the invention provides that the hot fluid preparation unit has a temperature control device, a fluid heating arrangement, a rectifier circuit and a power semiconductor switching device. The rectifier circuit is connected at an input of the rectifier circuit to an AC voltage supply and at an output of the rectifier circuit, via the power semiconductor switching device, to the fluid heating arrangement. The power semiconductor switching device is designed in a controllable manner such that it selectively switches through the output of the rectifier circuit to the fluid heating arrangement. The temperature control device is configured to control the power semiconductor switching device in a pulsed manner, in order thus to perform a temperature adjustment.

  • Patent number: 9829845
    Abstract: An image forming apparatus includes a controller configured to execute a discharging operation for discharging a toner from a developing device onto an image bearing member in a region corresponding to an interval between a recording material and a subsequent recording material in a continuous image forming job. The controller executes the discharging operation on the basis of integral information based on a relationship of a predetermined deterioration threshold with a value correlating with an amount of toner consumption. The controller changes the relationship based on a detected temperature upon toner consumption, and the controller changes the relationship so that when a temperature obtained on the basis of detected information is not less than a predetermined temperature, execution of the discharging operation is promoted more than when the obtained temperature is less than a predetermined temperature.

  • Patent number: 9791820
    Abstract: While a continuous conveying process is being executed, a first output process is executed at a timing prior to a prescribed timing, and a second output process is executed for a prescribed period from the prescribed timing. The prescribed timing is prior to a timing at which each recording sheet reaches a heating body. The first output process is for controlling an electric power supply to output electric power to a heat source configured to heat the heating body. The second output process is for controlling the electric power supply to output electric power to the heat source such that an output level of the electric power that is outputted from the electric power supply in the second output process has a tendency to become higher than an output level of the electric power that is outputted from the electric power supply in the first output process.
