Detailed description of the invention
The present invention will be described with reference to the accompanying drawings.In the drawings and in which, same label represents identical part or suitable part, suitably simplifies or omit the explanation that it repeats.
Embodiment 1
Fig. 1 is the block diagram of the control panel of the elevator that embodiments of the present invention 1 relate to.In the not shown hoistway that control panel 1 shown in this Fig. 1 is arranged on elevator or in not shown machine room, described machine room is arranged on the top of hoistway.Control panel 1 possesses housing 2.
This housing 2 is such as made up of magnetic substances such as metal sheets.Housing 2 is rendered as the box like being formed with opening at front surface.That is, housing 2 possesses the both sides face of back part, upper surface part, lower surface portion and left and right.Further, the front-surface side opening of housing 2.In the left and right edges of the opening of this front surface, be formed with the front surface left border portion 2a and front surface right border portion 2b with one fixed width.In the inner side of the housing 2 of the box like formed like this, the transformer 3 that the control circuit receiving elevator has.Specifically, transformer 3 is such as voltage transformer or reactor etc.
Magnetic screening sheet 4 is provided with at the opening part of the front surface of housing 2.This magnetic screening sheet 4 is made up of magnetic substance in the form of sheets.Magnetic screening sheet 4 has the elasticity of the degree that can reel.Spooler 5 is provided with at the front surface left border portion 2a of housing 2.Left end and this spooler 5 of magnetic screening sheet 4 link.Spooler 5 is configured to batch magnetic screening sheet 4 from left end side.Spooler 5 is made up of magnetic substance.The left end of magnetic screening sheet 4 is by means of this spooler 5 and housing 2 magnetic coupling.
The right-hand member of magnetic screening sheet 4 can by the front surface right border portion 2b of engaging portion 6 engaging in housing 2.This engaging portion 6 possesses the magnet installed near the right part of magnetic screening sheet 4.Further, by utilizing this magnet adsorption front surface right border portion 2b, the right-hand member of magnetic screening sheet 4 is engaging in front surface right border portion 2b thus.Make the right-hand member of magnetic screening sheet 4 by under the state of engaging portion 6 engaging in the front surface right border portion 2b of housing 2, the right-hand member of magnetic screening sheet 4 and housing 2 magnetic coupling.
In the control panel 1 formed like this, when elevator runs, magnetic screening sheet 4 is pulled out from spooler 5, utilize engaging portion 6 by the front surface right border portion 2b of the right part of magnetic screening sheet 4 engaging in housing 2.Like this, magnetic screening sheet 4 is configured to right border from the left border of the opening of the front surface of housing 2.
In this condition, the two ends, left and right of magnetic screening sheet 4 respectively with housing 2 magnetic coupling.Housing 2 and magnetic screening sheet 4 are all magnetic substances.Therefore, defined by housing 2 and magnetic screening sheet 4 and surround the magnetic substance circle all around of transformer 3 incessantly, thus the leakage magnetic field that produces due to the work of transformer 3 can be prevented to the outside of housing 2.
On the other hand, when worker etc. conducts interviews to the transformer 3 etc. in housing 2, be formed as relieving the locking such state of right part relative to housing 2 of the magnetic screening sheet 4 realized based on engaging portion 6.Further, utilize spooler 5 to batch and receive magnetic screening sheet 4.Like this, the opening open of the front surface of housing 2, worker etc. can easily access the various equipment such as the transformer 3 in housing 2 from this opening.
And, at this, magnetic screening sheet 4 to be pulled out from spooler 5 and engaging under the state (that is, defining the state of the circle of electromagnetic shielding performance) of engaging portion 6, if produce magnetic field from transformer 3, then in magnetic screening sheet 4, produce induced electric motive force due to this magnetic field.
Therefore, the LED circuit driven by means of the voltage (induced electric motive force) produced in magnetic screening sheet 4 also can be set on magnetic screening sheet 4.Like this, the voltage produced in magnetic screening sheet 4 when covering the magnetic field produced by transformer 3 can being effectively utilized, making the LED of LED circuit luminous, notifying that the transformers such as worker 3 are in work.
In addition, also can replace this LED circuit or together with LED circuit, the fan circuit utilizing the voltage (induced electric motive force) produced in magnetic screening sheet 4 to drive is arranged at magnetic screening sheet 4.Like this, the voltage produced in magnetic screening sheet 4 when covering the magnetic field produced by transformer 3 can being effectively utilized, being cooled in housing 2 by fan circuit.
Further, about engaging portion 6, except adopting except the example of magnet that this has been explanation, also projection or screw etc. can be adopted.In case bumps are used, such as, projection is set at front surface right border portion 2b, and, in the position of the correspondence of the right part of magnetic screening sheet 4, locking hole is set.Further, by making this projection be hooked in locking hole, locking magnetic screening sheet 4 is carried out.In addition, when adopting screw, the right part of magnetic screening sheet 4 is clipped in the head of screw and the rear of front surface right border portion 2b, and tightening screw, thus locking magnetic screening sheet 4.
The control panel of the elevator formed so above possesses: housing 2, it is made up of magnetic substance, in the machine room being arranged on elevator or in hoistway, be rendered as the box like being formed with opening at front surface, the transformer 3 that the control circuit being accommodated with elevator in the inner side of this box like has; With the magnetic screening sheet 4 as magnetic shield member, it is made up of magnetic substance, at least from the configuration of the left border of the opening of housing 2 to right border, and two ends, left and right respectively with housing 2 magnetic coupling.
Therefore, utilize the housing 2 as magnetic substance, magnetic screening is formed, thereby, it is possible to form magnetic screening in less space to the transformer 3 (voltage transformer, reactor etc.) in control panel.Therefore, it is possible to prevent magnetic field from leaking from being accommodated in inner transformer, and, while the maximization of the size of inhibitory control dish, the restriction of the shape to control panel can be tackled flexibly.
In addition, adopt the magnetic screening sheet 4 of sheet as magnetic shield member, and possess: spooler 5, it is located at an end of magnetic screening sheet 4, batches magnetic screening sheet 4 from this end side; With engaging portion 6, it is located at the other end of magnetic screening sheet 4, by this other end engaging in housing 2, thus, becomes easy when maintenance inspection etc. to the access in control panel.
