In description of the invention, need to prove, unless otherwise prescribed and limit, term " installation ", " linking to each other ", " connection " should be done broad understanding, for example, can be mechanical connection or electrical connection, also can be the connection of two element internals, can be directly to link to each other, and also can indirectly link to each other by intermediary, for the ordinary skill in the art, can understand as the case may be the concrete meaning of above-mentioned term.
With reference to following description and accompanying drawing, these and other aspects of embodiments of the invention will be known.These describe and accompanying drawing in, specifically disclose some particular implementation in the embodiments of the invention, represent to implement some modes of the principle of embodiments of the invention, still should be appreciated that the scope of embodiments of the invention is not limited.On the contrary, embodiments of the invention comprise spirit and interior all changes, modification and the equivalent of intension scope that falls into additional claims.
The interlock control apparatus that proposes according to the embodiment of the invention and the dryer with this interlock control apparatus are described with reference to the accompanying drawings.
As shown in Figure 1, the interlock control apparatus of one embodiment of the present of invention proposition comprises the first switch 1, starts module 2, motor 3 and second switch 4.
Wherein, second switch 4 is in parallel with startup module 2, and motor 3 is connected to the first switch 1 and second switch 4 and starts between the module 2, these motor 3 control second switches 4 closures when motor 3 rotates, these motor 3 control second switches 4 disconnect when motor 3 is static, motor 3 began to rotate when wherein, the first switch 1 closure and startup module 2 were triggered.
Need to prove that in an embodiment of the present invention, as shown in Figure 2, second switch 4 also can be integrated in motor 3 the insides, like this, second switch 4 and motor 3 are wholely set.
In one embodiment of the invention, the first switch 1 is door switch, and second switch 4 is centrifugal switch.And centrifugal switch belongs to mechanical type control, long service life, and reliability is high.In an example of the present invention, start module 2 and can be start button.
Further, in an embodiment of the present invention, as shown in Figure 1, centrifugal switch comprises the first contact a, the second contact b and the 3rd contact c, and the first contact a links to each other with motor 3 respectively with the 3rd contact b, when motor 3 rotated, this motor 3 passed through centrifugal force so that the 3rd contact c links to each other with the second contact b.
And motor 3 stops operating when door switch disconnects, and the 3rd contact c links to each other with the first contact a after motor 3 is static.
That is to say, after live wire L, zero line N energising, realize the control interlocking by door switch, centrifugal switch and start button.Wherein, after the door switch closure, the first contact a of centrifugal switch and the 3rd contact c connect, and the 3rd contact c and the second contact b disconnect, and motor 3 can't move at this moment, when pressing start button, and the power connection of motor 3, motor 3 can normally move.After motor 3 operations, because centrifugal action, centrifugal switch is linked to each other with the 3rd contact c by the second contact b, and this moment, start button unclamped, and motor 3 still can normally move by centrifugal switch.When door switch disconnected, motor power cut off, and motor 3 is out of service, and this moment, the first contact a of centrifugal switch linked to each other with the 3rd contact c, even after the door switch closure, still need be by start button, and motor 3 can move, thereby has realized interlock.
According to the interlock control apparatus of the embodiment of the invention, can realize the interlocked control of motor 3 operations has been improved security, reliability is high.And do not need to be equipped with electronically controlled interlock control apparatus, strong interference immunity has been saved cost, long service life again.
As shown in Figure 3, an alternative embodiment of the invention has also proposed a kind of dryer 200, and it comprises above-mentioned interlock control apparatus 100.
Wherein, this dryer 200 also comprises a (not shown), and the door of dryer 200 is corresponding with the door switch in the interlock control apparatus 100.When L, N switch on, by door switch, centrifugal switch and start button control interlocking.Operation mechanism is: after door was shut, the door switch contacting was that door switch is closed, and this moment, the first contact a and the 3rd contact c of centrifugal switch connected, the 3rd contact c and the second contact b disconnect, and motor 3 can't move, when pressing start button, the power connection of motor 3, motor 3 can normally move.After motor 3 operations, because centrifugal action, centrifugal switch is linked to each other with the 3rd contact c by the second contact b, and this moment, start button unclamped, and motor 3 still can normally move by centrifugal switch.After door was opened, door switch disconnected, and motor power cuts off, and motor 3 is out of service, and this moment, the first contact a of centrifugal switch linked to each other with the 3rd contact c, made door switch closed even door is shut, still need be by start button, and motor 3 can move, thereby realizes interlock.
According to the dryer 200 of the embodiment of the invention, can under the control of interlock control apparatus 100, realize interlock, do not need to be equipped with again electronically controlled interlock, strong interference immunity, reliability is high, and has saved cost.Wherein, centrifugal switch adopts mechanical type control, long service life, and reliability and security all are improved.
In the description of this specification, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present invention or the example in conjunction with specific features, structure, material or the characteristics of this embodiment or example description.In this manual, the schematic statement of above-mentioned term not necessarily referred to identical embodiment or example.And the specific features of description, structure, material or characteristics can be with suitable mode combinations in any one or more embodiment or example.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment that scope of the present invention is by claims and be equal to and limit.
