Illustrate below with reference to Fig. 8 control circuit 30 performed by switching mechanism 20 control it is detailed
Situation.Fig. 8 is the figure for representing to flow through the electric current of each several part of control circuit 30.In Fig. 8 (a),
Show to power with thick line each several part for flowing through control circuit 30 after just starting electric current path.
If to applying direct current between hot side power supply terminal PVDD and low potential side power supply terminal PVSS
24V is pressed, then electric current flows through the relay coil 312 of electromagnetic relay 31.Thus, electromagnetic relay
31 normally opened contact 310 is closed, and normally-closed contact 311 disconnects.Thus, electric current is via normally opened contact
310 flow to diode 35, delay cut-out contact 320 and relay coil 321.
Because normally-closed contact 311 disconnects, therefore flow through the electric current of diode 35 and flowed to via resistance 33
Capacitor 36.Further, since dash current is produced when electric current flows through capacitor 36, therefore series connection
Connection resistance 33 carrys out the charging dash current of suppression capacitor 36.Thus, capacitor 36 is charged.
Further, since reverse biased is applied to diode 34, therefore without flow through electric current.
The electric current for flowing through delay cut-out contact 320 flows to the 1st magnet coil 211.Thus, is passed through
Attraction under the effect of 1 magnet coil 211, plunger 215 advances to X-direction.As a result, bar portion
216 release open and close member 23, proceed to supported with ventilation mouth A as shown in FIG. 2 and 3
Untill the 1st position connect.Then, ventilation mouth A is by the occlusion of open and close member 23, the inside of car 10
It is maintained airtight.
If have passed through preset time from electric current flows through relay coil 321, for example, 0.5 second is have passed through,
Then delay cut-out contact 320 disconnects, shown in such as Fig. 8 (b), and electric current is to the 1st magnet coil 211
Inflow stop.Even if because electric current stops to the inflow of the 1st magnet coil 211, also by permanent magnet
213rd, plunger 215 and the formation magnetic circuit of yoke 214, therefore plunger 215 is made by its magnetic force
The 1st position is maintained at, ventilation mouth A is maintained at the state closed by open and close member 23.
If the charging of capacitor 36 is finished, such as shown in Fig. 8 (c), in the rear class of diode 35
Electric current is no longer flow through in path, electric current stops to the inflow of capacitor 36.
So, according to present embodiment, by flowing through preset time in the 1st magnet coil 211
Electric current, so that plunger 215 is moved to the 1st position, the mouth A that be able to will be taken a breath by open and close member 23 is closed.
In addition, since power supply after preset time, even if not making electric current flow through the 1st electromagnetism all the time
Coil 211, is also maintained at the 1st position, therefore can maintain to open by the magnetic circuit that is formed by plunger 215
The ventilation mouth A closed under component 23 is acted on occlusion.Taken a breath accordingly, it is capable to be closed with less consumption electric power
Mouthful A and maintain the state.
If because because stopping powering to control circuit 30 having a power failure etc., electric current is to relay coil 312
Inflow stop, therefore normally opened contact 310 disconnected, and normally-closed contact 311 is closed.Further, since electric
The inflow for flowing to relay coil 321 also stops, therefore delay cut-out contact 320 is closed.Due to normal
Closed contact 311 is closed, therefore forms the current path in Fig. 8 (d) shown in thick line, capacitor 36
Start electric discharge.In order to prevent the energy that resistance 33 is consumed in the electric discharge of capacitor 36 from becoming very big,
In the two ends parallel-connected diodes 34 of resistance 33.Further, since applying to diode 35 reversely partially
Pressure, therefore without flow through electric current in diode 35.
As a result, the discharge current of capacitor 36 mainly flows to the 2nd electromagnetism by diode 34
Coil 212, the attraction under being acted on by the 2nd magnet coil 212, plunger 215 is retreated to Y-direction.
By the retrogressing of plunger 215, the drawing open and close member 23 of bar portion 216, as shown in FIG. 4 and 5 that
Untill sample backs to the 2nd position that ventilation mouth A is opened.Then, opened by the mouth A that takes a breath, from
And release the airtight conditions of car 10.
If in addition, though the discharge off of capacitor 36, electric current is no longer flow through the 2nd magnet coil
212, but due to forming magnetic circuit by permanent magnet 213, plunger 215 and yoke 214, therefore pass through
Its magnetic force and plunger 215 is maintained at the 2nd position, ventilation mouth A is maintained at the state of opening.
So, according to present embodiment, by making the charging power of capacitor 36 discharge, so that
The electric current of preset time is flowed through in 2nd magnet coil 212, plunger 215 is moved to the 2nd position.Its
As a result, open and close member 23 will take a breath, mouth A is opened.In addition, after discharge off, even if not making electricity
Stream flows through the 2nd magnet coil 212 all the time, and plunger 215 is maintained at into the also by the magnetic circuit formed
2 positions, therefore the opening of the ventilation mouth A under the effect of open and close member 23 can be maintained.Accordingly, it is capable to
Less consumption electric power opens ventilation mouth A and maintains the state.
Afterwards, terminate if having a power failure, the power supply of DC voltage 24V to control circuit 30 is started again at,
Then electric current flows through the 1st magnet coil 211, again will ventilation mouth A occlusions (Fig. 8 by open and close member 23
(a) air-tightness (Fig. 8 (b) and Fig. 8 (c)) inside car 10 is maintained), therefore also later.
As more than, according to the present invention, due to do not make electric current flow through all the time the 1st magnet coil 211 and
2nd magnet coil 212, with regard to that can maintain the occlusion of the ventilation mouth A under the effect of open and close member 23 or open
Put, therefore inhibit the overall consumption electric power of elevator, and will not also make above-mentioned each magnet coil 211,
212 excessive heatings.Accordingly, it is capable to realize the ventilation for the car 10 for being arranged at elevator with less consumption electric power
Mouth A automatic shutter.In addition, the operation in these actions also without attendant etc..
