The operation of the control device of the elevator car fan 10 having the above-described structure is as follows:
1.1 Elevator initial Power-on
When the elevator is changed from the power-off state to the power-on state, on one hand: the door-opening switch KM and the door-closing switch GM are not actuated, so that the second relay JF2 and the third relay JF3 are not attracted, and the normally-open contact b2 and the normally-open contact b3 are both disconnected, so that the fourth relay JF4 and the fifth relay JF5 are both in a release state, and the normally-open contact a4 of the fourth relay JF4 is disconnected, on the other hand: the first relay JF1 is in a released state at the time of elevator power failure state, and its normally open contact a1 is opened. In summary, it can be seen that: when the elevator is turned to the power-on state, the first relay JF1 is continuously kept in the release state, so that the normally closed contact d1 is in the on state.
1.2 door opening switch KM and door closing switch GM are pressed simultaneously
When the door-opening switch KM and the door-closing switch GM are pressed down simultaneously, the second relay JF2 and the third relay JF3 attract each other, and the normally open contact b2 and the normally open contact b3 are both connected, as can be seen from fig. 2, the normally closed contact b1 and the normally closed contact b5 at the front end of the fourth relay JF4 are both in a connected state, while the normally open contact c1 and the normally open contact c5 at the front end of the fifth relay JF5 are both in a disconnected state, so that the fourth relay JF4 attracts each other, and in the attracting process of the fourth relay JF4, the normally closed contact c4 thereof is firstly disconnected, so that the fifth relay JF5 cannot attract each other, and then the normally open contact a4 is connected, so that the first relay JF1 attracts each other. When the door opening switch KM and the door closing switch GM are loosened, the second relay JF2 and the third relay JF3 are released, the normally open contact 2 and the normally open contact b3 are disconnected, and therefore the fourth relay JF4 and the fifth relay JF5 are both in a release state. After the first relay JF1 is attracted, the normally open contact a1 is turned on, so when the door opening switch KM and the door closing switch GM are released, the first relay JF1 is still in the attracted state. After the first relay JF1 is switched from the release state to the pull-in state, the normally closed contact d1 thereof is opened, so that the power circuit of the fan 10 is switched from on to off, thereby completing the switching of the operating state of the fan 10.
1.3 door opening switch KM and door closing switch GM are pressed down again at the same time
When the door opening switch KM and the door closing switch GM are pressed down simultaneously again, the second relay JF2 and the third relay JF3 attract each other, and the normally open contact b2 and the normally open contact b3 are both connected. As can be seen from 1.2, since the first relay JF1 is held in the attraction state, the normally closed contact b1 at the front end of the fourth relay JF4 is opened, and the normally open contact b4 is opened, so that the fourth relay JF4 is in the release state. The normally open contact c1 at the front end of the fifth relay JF5 is switched on, and the normally closed contact c4 is switched on, so that the fifth relay JF5 is attracted, the normally closed contact a5 is disconnected, the normally open contact c5 is switched on, the first relay JF1 is switched to a release state from attraction, the normally closed contact d1 is further switched on, a power circuit of the fan 10 is switched to be on from disconnection, and the switching of the working state of the fan 10 is completed again. Then, the door opening switch KM and the door closing switch GM are released, the second relay JF2 and the third relay JF3 are both released, and the normally open contact b2 and the normally closed contact b3 are both opened, so that the fourth relay JF4 and the fifth relay JF5 are both in a released state, while the first relay JF1 remains in a released state, that is, the fan 10 remains in an opened state.
In the operation process, the door opening switch KM and the door closing switch GM are pressed down and then released at the same time, the state of the first relay JF1 is switched to release, and at this time, the state of the whole switch state switching circuit is the same as the initial power-on state in the above-mentioned 1.1.
In summary, the final state of the first relay JF1 in the above operation process 1.3 is the same as the final state in 1.1, and therefore, when the door opening switch KM and the door closing switch GM are pressed down simultaneously a plurality of times, the first relay JF1 will cycle between the final state of 1.3 and the final state of 1.2, that is, the first relay JF1 cycles between the release state and the attraction state, thereby causing the fan 10 to cycle between opening and closing.
In addition, when the relay is switched from the release state to the pull-in state, the normally closed contact is opened firstly, and the normally open contact is closed after a certain reaction time. In the operation process of 1.3, when the first relay JF1 is powered, the normally closed contact a5 is firstly opened, so as to disconnect the power supply loop of the first relay JF1, and the normally open contact c5 is closed after a certain reaction time, if the normally open contact c5 cannot be closed before the closed normally open contact c1 is opened, the first relay JF1 and the fifth relay JF5 will oscillate between the attraction state and the release state in turn, so that before the door opening switch KM and the door closing switch GM are released, the power supply loop of the first relay JF1 may be connected again, and the conversion failure is caused. Therefore, two ends of the first relay JF1 are also electrically connected to an energy storage module, and the energy storage module can provide short-time electric quantity for the first relay JF 1. Preferably, the energy storage module comprises an RC series circuit consisting of a capacitor C1 and a resistor R1.
In the above operation process 1.1, when the elevator is initially powered on, the energy storage circuit formed by the capacitor C1 and the resistor R1 connected in series does not store energy, and the state of the first relay JF1 is not affected. In the above operation process 1.2, the first relay JF1 is in the pull-in state, and charges the energy storage circuit formed by the capacitor C1 and the resistor R1. In the above operation process 1.3, after the fifth relay JF5 is powered, the normally closed contact a5 thereof is opened first, thereby disconnecting the power supply circuit of the first relay JF 1. At the moment, an energy storage circuit formed by a capacitor C1 and a resistor R1 discharges to the first relay JF1, so that the first relay JF1 still keeps in an attraction state, the capacitor C1 and the resistor R1 with proper specifications are selected, the first relay JF1 continues to keep in the attraction state for time t, t is more than or equal to 0.1s and less than or equal to 0.4s, so that the normally-open contact C5 of the fifth relay JF5 has enough time to be switched on, and the state conversion failure of the first relay JF1 is avoided. When the energy of the energy storage circuit is consumed, the first relay JF1 is switched to a release state and is held in this state.
For saving electric energy, as shown in fig. 3, a fourth trigger switch 23 electrically connected to the elevator control system is further connected in series in the power circuit of the fan 10. When the elevator is in an idle state, the elevator control system can control the fourth trigger switch 23 to be in an off state, so that the power supply of the fan 10 is turned off.
To sum up, the utility model discloses a be provided with vertical elevator of elevator car fan controlling means, fan 10 has opened (or closed), and the passenger can press down simultaneously door opening switch KM, door closing switch GM and loosen again for first relay JF1 truns into the actuation state from the release state (or truns into the release state from the actuation state), makes normally closed contact d1 disconnection (or switch-on), thereby closes (or opens) fan 10.
The above disclosure is only a preferred embodiment of the present invention, and certainly, the scope of the present invention should not be limited thereto, and therefore, the scope of the present invention is not limited to the above embodiments.
