Health elevator device

Abstract

The invention discloses a health elevator device. The health elevator device consists of an elevator control cabinet transformer unit, a single-phase inverter power module unit, a boosting transformer unit, a normal / power failure conversion circuit unit, a voice player, a fan, a negative ion generator, a single-phase inverter pulse width modulation (PWM) wave generator, a storage battery and a charging / discharging unit, wherein negative ions of the negative ion generator are fed into a cage by using the fan; when an external power grid is operated normally, the power of the negative ion generator and the power of the fan are supplied by the external power grid; when the external power grid is operated abnormally, the power of the negative ion generator and the power of the fan are supplied by a backup reverse power supply; and when the power fails, the power of the voice player is supplied by the storage battery, and the voice player plays light music and calm voice. The health elevator device can not only be used for a new elevator, but also be used for changing a control system of an old elevator. When the power fails, a backup power supply is adopted for supplying power, an airenvironment of the cage cannot change badly because of the failure of the power, and the light music and the calm voice are played in time, so that intense sentiment, generated because of the power failure, of passengers is eased.

Description

technical field [0001] The invention relates to a healthy elevator device, which belongs to the technical field of elevators. Background technique [0002] With the increasing number of high-rise buildings, more and more elevators have entered people's lives, which not only brings benefits to people, but also affects everyone's physical and mental health. [0003] The elevator car is installed in a closed and narrow well. In addition, the area of ​​the car itself is small, and the passenger flow is large during the peak period of elevator operation, resulting in low air quality in the entire car, which is harmful to the health of passengers. Big. Especially when the elevator encounters a sudden power failure and passengers are waiting for rescue, because there is no power to provide the fan in the car to stop, the air cannot form convection, which will cause CO 2 The increase in gas content, the sharp rise in temperature, and the lack of oxygen supply directly lead to anxi...

Problems solved by technology

[0003] The elevator car is installed in a closed and narrow well. In addition, the area of ​​the car itself is small, and the passenger flow is large during the peak period of the elevator operation, resulting in low air quality in the entire car, which is harmful to the health of passengers. Big

Especially when the elevator encounters a sudden power failure and passengers are waiting for rescue, because there is no power to provide the fan in the car to stop running, the air cannot form convection, which will cause CO 2 The increase in gas content, sharp rise in temperature, and insufficient oxygen supply directly lead to anxiety among passengers. Moreover, due to the dirty air, many passengers will have difficulty breathing and even faint. The consequences are serious and unimaginable
