Problems solved by technology
However, when the existing exhaust fan is performing exhaust work, the operating power is constant, that is, the air output is constant, and the air output is always maintained at a relatively large air output. In practical applications, the number of passengers in the elevator car is always changing. state, when the number of passengers is small, a large air volume is not required, that is to say, the existing exhaust fan cannot control the air volume according to the number of passengers inside the car, so it consumes more energy

Embodiment approach
[0018] Wherein, as an embodiment of the present invention, the drive motor 6 is provided with a car closing confirmation module 12 connected to the elevator control system 11, which is used to confirm whether the car door is in a closed state. When the door body is in the closed state, the drive motor 6 will perform the corresponding expansion and contraction control on the automatic expansion cover 7, otherwise the expansion and contraction control will not be performed.
[0019] In practical applications, when the elevator car door is opened, people will go inside the elevator one after another. At this time, if the automatic telescopic cover 7 is controlled for expansion and contraction, it will easily cause the drive circuit to heat up due to the continuous switching of the air volume. Therefore, in order to operate more effectively, Will just carry out according to the corresponding automatic telescoping cover 7 telescoping control of the number of passengers when the elev...

An energy-saving elevator car ventilation system with an air outlet automatically shielded. The energy-saving elevator car ventilation system comprises an exhaust fan, the air outlet, an exhaust pipe, a camera device, a control center, a driving motor and an automatic stretching and contracting cover, wherein the exhaust fan and the air outlet are communicated through the exhaust pipe, the automatic stretching and contracting cover is arranged below the air outlet, and one end of the automatic stretching and contracting cover is fixed to the side wall of an elevator car. The driving motor controls the automatic stretching and contracting cover to stretch and contract. The control center comprises an image recognition module, a processor module and a database, and a relation comparison table of people number sections and air outlet grades is stored in the database. The camera device shoots images of the interior of the elevator car in real time, the control center carries out recognition through the image recognition module, specifically recognizes the number of people taking an elevator and transmits the number of people taking the elevator to the processor module, the processor module obtains a corresponding air outlet grade from the database according to the people taking the elevator, the control center sends the obtained air outlet grade to the driving motor, and the driving motor carries out corresponding stretching and contracting control over the automatic stretching and contracting cover according to the air outlet grade.
Description
technical field [0001] The invention relates to the technical field of elevator ventilation, in particular to an energy-saving elevator car ventilation system with automatic blocking of air outlets. Background technique [0002] In order to improve the air inside the elevator car and improve the comfort of the elevator passengers, the existing elevator is equipped with an exhaust fan in the car to ventilate the inside of the car. However, when the existing exhaust fans perform exhaust work, the operating power remains unchanged, that is, the air output volume remains constant, and the air output volume is always maintained at a large air output volume. In practical applications, the number of passengers in the elevator car is always changing. state, when the number of passengers is small, a large air volume is not required, that is to say, the existing exhaust fan cannot control the air volume according to the number of passengers inside the car, so it consumes more energy ...
