Embodiment Construction

[0013] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] figure 1 It is a schematic diagram schematically showing one embodiment of the elevator of the present invention. Such as figure 1 As shown, an elevator 100 includes a hoistway 102, a car 104, a counterweight 106, and the like. A machine room 110 is provided above the hoistway 102 . The machine room 110 is provided with a traction machine 112 and a control device 114 . The car 104 and the counterweight 106 are connected by a traction rope 108 , and the traction rope 108 is wound on the traction sheave of the traction machine 112 . The car 104 and the counterweight 106 are driven up and down in the hoistway 102 by the traction machine 112 . A traveling cable 116 is connected between the control device 114 and the car 104 . The control device 114 provides power to the car 104 through the accompanying c...

Abstract

The invention relates to an elevator, and a control method and control device thereof. An elevator car of the elevator is provided with a ventilation window. The control method comprises the followingsteps of opening an elevator car door and the ventilation window simultaneously; closing the elevator car door; and closing the ventilation window after detecting that the elevator car door is closed. Thus, the ventilation efficiency and effect of the elevator car are greatly improved, and burden brought to a driving mechanism of the ventilation window by cross ventilation can be reduced.

Description

technical field [0001] The invention relates to an elevator and its control method and control device. Background technique [0002] In recent years, with the high-rise buildings, people's requirements for elevator speed are also increasing. However, due to the rapid change of air pressure when the high-speed elevator goes up and down, passengers often feel uncomfortable due to the feeling of plugging their ears. In order to prevent this phenomenon, many elevator cars are equipped with air pressure control devices to control the air pressure in the car. Moreover, in order to improve the control effect of the air pressure, the car of this elevator has a high airtightness. However, high airtightness may lead to poor ventilation in the car, unable to introduce fresh air in time, and even lead to hypoxia. [0003] Japanese Patent Publication No. 2011-57414 discloses an elevator ventilation device. The ventilation device includes a car air pressure control device, a ventilati...
