Outer surface 17 has along the circumferential length of the second cam 14.The radial distance of the rotating shaft of relative the second cam 14 everywhere of outer surface 17 is identical.Outer surface 17 is preferably smooth continuously.
Below describe the step that closing element 5 is opened to open position from closed position in detail.
As mentioned above, closing element 5 is in the closed position under normal conditions, and movable terminal 8 is connected with the first terminal 9.The end of cam follower 15 is corresponding to the connecting portion 36 of the second cam 14, as shown in Figure 4.
In the time that user starts ice dispense switch 31, therefore the state of ice dispense switch 31 changes and produces first signal and send control module 11 to.Control module 11 is receiving after first signal, and the first terminal 9 is connected with the working power of motor 6.Meanwhile, control module 11 is supplied with the first supply time T1 timing of power supply to the first terminal 9.
Now, because movable terminal 8 is connected with the first terminal 9 and the first terminal 9 is connected with the working power of motor 6, motor 6 is switched on and entry into service.Cam body 26 starts rotation under the driving of motor 6, and cam follower 15 enters in the groove 37 of the second cam 14 and along with the second cam 14 rotate together, and then drive closing element 5 rotates towards open position from closed position.
In the time that closing element 5 rotates to open position, as shown in Figure 5, the operating knob 18 of the switch 7 and jut 34 of the first cam 13 is conflicted and the latter exerts pressure to operating knob 18, and then make movable terminal 8 change position.The connection of movable terminal 8 and the first terminal 9 disconnects, and switches to the second terminal 10 and be connected.Meanwhile, the end of cam follower 15 be resisted against head 16 outer surface 17 one end and in highest point, closing element 5 rotates to maximum open position.
Along with movable terminal 8 and the first terminal 9 disconnect, the power supply of supplying with motor 6 is disconnected, thereby motor 6 disconnects.
In addition, when the first supply time T1 being powered when the first terminal 9 reaches the first scheduled time Ta, control module 11 disconnects being connected of the first terminal 9 and working power.
The time of the first scheduled time Ta is configured to be greater than or equal to the time of closing element 5 from closed position motion arrival open position, and before guaranteeing that closing element 5 completes opening action, motor 6 can be worked.Best, the time of the first scheduled time Ta is configured to be a bit larger tham closing element 5 and arrives the required time of open position from closed position motion.
In the process of opening at closing element 5, the working power of motor 6, by switch 7 and control module 11 dual control independently, completes after the program of opening closing element 5, and motor 6 can be closed reliably.
In the time that closing element 5 is opened, the ice being kept in refrigerating appliance 1 can be assigned to refrigerating appliance 1 outside by ice transfer passage 4.Below describe the bolt down procedure of closing element 5 in detail.
First, refrigerating appliance 1 produces a secondary signal that stops distributing ice.Secondary signal can be based on user the operation to ice dispense switch 31 and producing, for example user stops the operation to ice dispense switch 31 or again operates ice dispense switch 31.In a further embodiment, the signal of the timing unit that secondary signal also can be based on control module 11 produces, or according to from control module 11 work associated the sensor arranging signal and produce.
Based on secondary signal, control module 11 supplies power supply to the second terminal 10.Meanwhile, control module 11 is supplied with time T 2 timing of power supply to the second terminal 10.Because now closing element 5 is in an open position, movable terminal 8 and the second terminal 10 are connected, and therefore motor 6 is switched on again, and drive the first cam 13 and the second cam 14 to continue rotation.
In the time that the second cam 14 continues rotation, the outer surface 17 of the end of cam follower 15 and head 16 relatively moves.Because outer surface 17 is that cylinder is planar, and the radial distance of the rotating shaft of relative the second cam 14 is equal everywhere, and therefore, although relative the second cam 14 of cam follower 15 relatively moves, its relative ice transfer passage 4 does not have occurrence positions to change.That is to say, although the second cam 14 has started rotation, closing element 5 still remains on open position.
Owing to still remaining on open position in closing element 5 a period of time after secondary signal produces, that is to say closing element 5 and close because coordinate between the second cam 14 and cam follower 15 to lag behind one period of time delay.Arrive distribution cavity 24 thereby the ice of ice container 21 interior discharges has time enough to pass ice transfer passage 4, this has been avoided because ice is trapped in the situation generation that near closing element 5 closing element 5 and that cause is frozen in.
Along with the continuation rotation of the second cam 14, cam follower 15 finishes with the relative sliding of outer surface 17, and cam follower 15 leaves outer surface 17 and enters connecting portion 36 regions.Meanwhile, the jut 34 of the first cam 13 is removed the compressing of operating knob 18, and operating knob 18 enters lower curtate 34 regions, and then movable terminal 8 is disconnected with the second being connected of terminal 10, and recovers being connected of movable terminal 8 and the first terminal 9.Along with the connection of movable terminal 8 and the second terminal 10 is disconnected, motor 6 is disconnected power supply.
In addition, when the second supply time T2 that is supplied with power supply when the second terminal 10 reaches the second scheduled time Tb, control module 11 disconnects being connected of the second terminal 10 and power supply.
The second scheduled time Tb is configured to be greater than or equal to the required time of cam follower 15 from one end circumferential movement of outer surface 17 to the other end, to guarantee that motor 6 can work before cam follower 15 leaves outer surface 17.The second scheduled time Tb is preferably a bit larger tham the required time of cam follower 15 from one end circumferential movement of outer surface 17 to the other end.
After outer surface 17 is disengaged cam follower 15 resist forces, closing element 5 is got back to closed position and is maintained at closed position under the effect of torsion spring 27.
Should be appreciated that above is only most preferred embodiment of the present invention, and the present invention should not be limited to this.For example, in above embodiment, the change-over switch of switch 7 for changing in two-way circuit, but in other embodiment, if need not drive by drive unit in the process of closing at closing element 5, switch 7 can be also obviously single channel stopcock.
In addition, above using ice transfer passage 4 and close module 19 and illustrate as most preferred embodiment.But should be appreciated that the present invention can be applied in other occasions.For example, the present invention also go in refrigerating appliance for controlling the air door of Air Flow.
