  • Patent number: 10774942
    Abstract: [Object] An electric valve control device capable of preventing a start delay of an electric valve control (an opening degree control) by shortening a waiting period of a system control device and an electric valve device including the same are provided. [Solving Means] An electric valve control device 11 outputs a signal indicating an end or an interruption of an initialization operation to an air conditioner ECU 16 after the initialization operation of the electric valve 9 ends or is interrupted.
    Type: Grant

  • Patent number: 10571875
    Abstract: To provide an electric valve control device capable of preventing a delay at the time of starting a control of an electric valve by shortening a standby time of an air conditioner or the like when power is input again or a sleep mode is cancelled and an electric valve device including the same. After receiving a power-off signal predicting a power-off operation of an electric valve 9 or a sleep transition signal predicting a sleep mode transition operation thereof from an outside, (current) valve opening degree information at the time of stopping an operation of the electric valve 9 is stored in an EEPROM (a nonvolatile storage unit) 11c. At the time of inputting power again or cancelling a sleep mode, the current (immediately precedent) valve opening degree information stored in the EEPROM 11c is read from the EEPROM 11c to resume a control of the electric valve 9.
