Elevator car fan control device and vertical elevator

Abstract

The invention discloses an elevator car fan control device and a vertical elevator. The elevator car fan control device comprises a first trigger switch and an on-off state conversion circuit. The first trigger switch is electrically connected with a fan. The on-off state conversion circuit comprises a signal acquisition unit, a conversion unit and a control unit. The signal acquisition unit is used for acquiring the working states of a door opening switch and a door closing switch. The control unit is electrically connected with the first trigger switch. When the signal acquisition unit detects that the door opening switch and the door closing switch are simultaneously operated, the conversion unit converts and keeps control signals output by the control unit. According to the elevator car fan control device, the fan is controlled through the original door opening switch and the original door closing switch in an elevator car, it is not needed to form holes in the elevator car for mounting of other switches for controlling the fan, convenience is brought for passengers, the existing structure of a trim of the elevator car cannot be damaged, and the user experience can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator car fan control device and a vertical elevator that are convenient for passengers to control independently. Background technique [0002] In order to provide passengers with a comfortable elevator riding environment, fans are generally installed in the elevator car to blow the fresh air or cold air from the outside into the car, but now the fans in the elevator car are generally automatically activated by the system. Control, passengers cannot control its opening and closing, and the fan is generally on or off for a long time (during elevator operation). When the passenger feels cold, the fan cannot be turned off; when the passenger feels stuffy, the fan cannot be turned on. This contradiction is especially evident in the seasons when the temperature difference between day and night is large. [0003] If conventionally, a switch for controlling the fan is a...
