Embodiment describes in detail
An embodiment (seeing Fig. 1 and Fig. 2) of switchgear 100 can link the user mutually with electric controller, and electric controller can utilize the one-way communication voltage source to switch on to electric heater.Switch 100 comprises two cover dry type contacts 125.The first cover contact 125 is used for disconnecting the power supply that leads to heater and/or other controlled device.The second cover contact 125 for signal lamp/or other be used for device energized into the user feedback signal.Start by rotary switch axle 105 contact 125.Switch shaft 105 links to each other with camshaft 110, and camshaft 110 can be opened (seeing Figure 1B) and closing contact 125 by cam 150 with the predetermined anglec of rotation.In the rotary course of axle, contact 125 can be opened or closed with the identical anglec of rotation/also can be set at the different anglecs of rotation and be opened or closed.
Can load onto a knob so that use at an end of switch shaft 105.The other end of switch shaft 105 passes switch case 115 and is connected to camshaft 110.Switch shaft 105 may slide in the camshaft 110.Spring 120 is located at camshaft 110 the insides and between camshaft 110 and switch shaft 105.Spring 120 applies an active force on switch shaft 105, make axle 105 remain on the position of stretching out.Being placed on axle 105 with suitable retainer is taken in and when switch shafts 105 are in extended position switch shaft 105 can not be dropped out.Have only enough big active force is affacted on the switch shaft 105, the block that is located on the switch case 115 just allows axle 105 rotations.For driving switch, the user can at first inwardly depress predetermined distance with switch shaft 105, uses the active force rotating shaft 105 of pre-sizing then.In order to close swap switch, the user should rotate back to off-position with axle 105.The spring 120 that is located at the inside forces switch shaft 105 to return latched position.This just makes switch 100 have the advantages that two steps opened, a step closes, and this is that release mechanism is ratified necessary requirement.
One end of camshaft 110 and the central contact of potentiometer 130 interconnect (see figure 2).In the time of camshaft 110 rotations, the resistance between potentiometer 130 output leads changes along with the variation of camshaft angle position.The simulation potentiometer 130 that is integrated with switch junctions allows vicissitudinous output valve.This output can be used for potentiometric mechanical movement is linked mutually with microcontroller.Like this, just can manually be that heater or other device is selected any one (see figure 3) in the power setting of predetermined number.
Fig. 4 shows the another one embodiment of switch module.Switch module comprises axle; First switch S 1 and second switch S2; Potentiometer 130, potentiometer 130 comprise first terminals and second terminals; And controller.First switch S 1 can be connected to one first device, and second switch S2 can be connected to one second device.First device can comprise heating element 510, and second device can comprise indicating device 515, such as the indicator light (see figure 5).Axle links to each other with second switch S2 with first switch S 1, and can manual depression then (i) turn to primary importance, install selectively power supply is connected to first by first switch; And (ii) turn to the second place, selectively power supply is connected to second device by second switch.Potentiometer 130 links to each other with axle, but and provides the resistance value of a modulation according to the manual position of rotation of shaft assembly between first terminals and second terminals.Controller links to each other with potentiometer 130, but and according to the resistance value of modulation between potentiometer first terminals and second terminals control be transported to first the device and/or second the device power.Controller can comprise an electric controller 505 (such as a known electric controller).Electric controller 505 just can be controlled the power that is transported to first device and/or second device electrically.
In a word, power contact can and be closed with different axle anglec of rotation startings.This just makes some incident can carry out before giving the heater energized in the next incident of beginning as starting the blower fan cooling fan.Potentiometer has the function that two steps opened, a step closes, and this is that release mechanism is ratified necessary requirement.When potentiometer was used as change over switch, potentiometer can withstand very big current requirements in starting with when cutting out the such load of heater.Potentiometer can comprise an interim retainer that is arranged in slide or central contact stroke, and switch can have the ability that forms interface with the electric power controller.
The customer controller of a rotary type rotary switch as electric stove depressed in an embodiment utilization.This switch can be used as the interface of electric controller, and itself controls the power of being defeated by electrical heating elements again this electric controller.The user feels to be familiar with to rotary switch and is comfortable, also has the advantage of electric cooking control simultaneously.
Fig. 5 shows the embodiment of a cooking controller assembly.This cooking system can comprise a user interface that can engage in the dialogue with electric controller 505, and electric controller 505 itself is regulated the power of heater 510 again.This interface can comprise that is depressed a rotary type rotary switch 100, rotary switch can be as the control interface of electronic heater controller 505, depress a rotary type rotary switch by installing one, the user just can use the electronic-controlled installation of prior art to cook, and also has simultaneously to use the comfortable of rotary switch and sensation.Two steps were opened the function (the necessary requirement of release mechanism approval cook utensil) of closing with a step does not need redundant circuit.This connection and the mechanical device that cuts off the heating element power supply has eliminated because touch sensitivity is low, because food splashes cooktop surface or plate is put into or comes to the switch activated problem of bringing mistake or at random that touch pads takes place.Can not produce mistake or at random switch activated owing to radio frequency and electric field disturb yet.Moisture on glass does not have any influence to the action of switch.Interface switch has the ability that adjustable simulated signal is provided for microcontroller 505.Microcontroller 505 itself can be controlled the power that provides to heating element 510 again, and this just makes the temperature that the user can point-device control heating element 510, such as gentle low temperature in point-device control.Rotary switch 100 is structurally very sturdy and durable, can resist because the infringement that is caused in family's chemical article is misapplied and be exposed to machinery.
The cooking controller assembly comprises heating element 510, shaft assembly, switch, and electric controller 505.Heating element 510 links to each other with electric controller 505 with switch.Shaft assembly links to each other with switch, and moves up along first direction and second party with respect to heating element 510, optionally power supply is connected to heating element 510 by switch.Shaft assembly comprise one can hand rotation knob.Switch comprises one and depresses-the rotary type rotary switch.Electric controller 505 links to each other with switch and heating element 510, and according to the power that comes electronic control heating element 510 at the movement position of the first direction of shaft assembly and/or second direction.Controller 505 can comprise one or more microprocessor, microcontroller or other array of logic elements.Equally, electric controller 505 can comprise the EU-PPS control device of Diehl and the ULCL control device of Diehl etc.In the motion of first direction and the motion of second direction can be the motion of equidirectional.The power of heating element can provide by the one-way communication voltage source.
The content of previously described embodiment is to allow persons skilled in the art can make or use the present invention, can carry out various modifications to these embodiment, here the General Principle of Ti Chuing also can be applied among other embodiment, but the present invention is not limited to top illustrated embodiment and/or the configuration of any one special construction, and should be consistent with the widest range that meets disclosed by any way principle and features of novelty here.
