Description
The utility model relates to the household electrical appliances function control switch, specifically is a kind of bidirectional pulse rotary switch, belongs to household electrical appliances control device technical field.
The household electrical appliance of at present commercially available computer control, its functional select switch is that button is pressed switch, the user need constantly press shift knob and select when carrying out function selecting, and the functional sequence direction is single loop direction, can not rollback.For example: a certain button has 9 kinds of difference in functionalitys, when wanting selection function 9, need press shift knob 8 times from function 1 starting point, just can choose bit function 9.If pressed slightly because of carelessness more, because the functional sequence direction that is provided with is single loop direction, then make function selecting get back to the state of function 1 again, can't rollback, can only choose function 9 from function 1 once more, press shift knob once more and select.Such operation results in hand cramps, and is very inconvenient, loses time.Especially in the household electrical appliances of function selecting complexity, this kind inconvenience is more outstanding.
The purpose of this utility model is the defective that will overcome the above-mentioned functions selector switch, and a kind of bidirectional pulse rotary switch is provided.This switch will have two-way circulatory function, can the rollback selection function, need not constantly to press the two-way choice that switch just can be realized program.
Task of the present utility model is finished by following technical scheme, developed a kind of bidirectional pulse rotary switch, it comprises chassis and rotating shaft, on the card of chassis, be provided with concentric outside, in, internal touch track cycle, three these rail circles are connected on the microprocessor by lead respectively, the rotating shaft of vertical card is set on the concentric of this dish, the lower end of this rotating shaft is provided with the slip contact of conduction, this sheet be provided with three correspondences outer, in, interior contact, the corresponding respectively contact in three these contacts is on corresponding rail-engaging circle.
Described outer rail-engaging circle, its inner ring be along being provided with uniform interior double wedge, described internal touch track cycle, its outer ring is along being provided with uniform outer double wedge, described in the rail-engaging circle, its circle is along being the rail-engaging circle of circumferential.
Described inside and outside double wedge, its double wedge number are 12 or 24, and the location central angle of inside and outside double wedge is: 7.5 degree or 3.75 degree.
Described outer, in, interior contact, wherein in the eternal sliding contact in contact on middle rail-engaging circle; Interior contact is by contacting outside on the double wedge location status of rail-engaging circle and interior rail-engaging conducting in the formation; Outer contact is by contacting on interior double wedge the location status of rail-engaging circle and the conducting of outer rail-engaging circle in the formation.
Advantage of the present utility model is: the rotating shaft rotation drives the slip contact and the contact makes outside the band respectively owing to having designed, the inside and outside rail-engaging circle and the conducting of middle rail-engaging circle of interior double wedge, gives microprocessor thereby send Continuity signal.Just send signal by the positive and negative rotation of control rotating shaft, microprocessor just can be realized the two-way choice of program, and the selection function order so just transfers function setting to the program setting of microprocessor inside, thereby keep the external switch generality of hardware, reduced the production cost of hardware.This switch has replaced the original selection of pressing by the selection of rotating shaft direction of rotation, has simplified operating performance, has saved select time, has realized the universal standardization of switch hardware, and in the function selecting control apparatus of this switch application washing machine, effect is excellent.
Embodiment accompanying drawings of the present utility model is as follows:
The structural profile schematic diagram of Fig. 1 bidirectional pulse rotary switch;
The structural principle schematic diagram of Fig. 2 bidirectional pulse rotary switch (vertical view of Fig. 1).
Make a secondary bidirectional pulse rotary switch referring to Fig. 1, Fig. 2, it comprises: chassis 9 and rotating shaft 10.On 9 cards of chassis, be printed with concentric outside, in, internal touch track cycle 1,0,2.Three these rail circles 1,0,2 are connected on the microprocessor (not drawing among the figure) by lead (not drawing among the figure) respectively.The rotating shaft 10 that on the concentric of this dish 9, is provided with.The lower end of this rotating shaft 10 is provided with the slip contact 5 of conduction.This sheet 5 be provided with three correspondences outer, in, the corresponding respectively contact in 6,7,8, three these contacts 6,7,8 of interior contact is on corresponding rail-engaging circle 1,0,2.
The inner ring of rail-engaging circle 1 is along being provided with uniform interior double wedge 3 outside.On the edge, outer ring of internal touch track cycle 2, be provided with uniform outer double wedge 4.The circle edge of middle rail-engaging circle 0 is a circumferential.Double wedge 3 was 12 in this example was set, and outer double wedge 4 is 12.The location central angle of inside and outside double wedge 3,4 is 7.5 degree.The middle contact 7 of design will contact forever on middle rail-engaging circle 0.The interior contact 8 of design can contact outside on the double wedge 4, thus the location status of rail-engaging circle 0 and internal touch track cycle 2 conductings in constituting.In the outer contact 6 of design can contact on the double wedge 3, thus the location status of rail-engaging circle 0 and outer rail-engaging circle 1 conducting in constituting.
For further specifying the operation principle of this switch, set: the conducting between middle rail-engaging circle 0 and the outer rail-engaging circle 1 is defined as 1; Conducting between middle rail-engaging circle 0 and the internal touch track cycle 2 is defined as 2; Middle rail-engaging circle 0 is defined as 0 with all the other not conductings.And set: slip contact 5 stops in the position of not conducting 0 and conducting 1.
One, when slip contact 5 is in the location status of not conducting 0, as the position of Fig. 2 solid line slip contact 5:
1, this moment, microprocessor was received the Continuity signal order when this sheet 5 clockwise rotates:
1→2→0→1→2→0→……；
2, this moment, microprocessor was received the Continuity signal order when this sheet 5 rotates counterclockwise:
2→1→0→2→……；
Two, when slip contact 5 is in the location status of conducting 1, as the position of Fig. 2 dotted line slip contact 5:
1, this moment, microprocessor was received the Continuity signal order when this sheet 5 clockwise rotates:
2→0→1→2→0→……；
2, this moment, microprocessor was received the Continuity signal order when this sheet 5 rotates counterclockwise:
0→2→1→0→2→……。
In sum, receive when microprocessor ... 1 → 2 → 0 → 1 ... Continuity signal when order, the rotation of rotating shaft 10 this moment under any location status all can be judged as and clockwise rotate.
When microprocessor is received ... 2 → 1 → 0 → 2 → ... Continuity signal when order, the rotation of rotating shaft 10 this moment under any location status all can be judged as and rotate counterclockwise.Positive and negative rotation that so just can be by rotating shaft is sent the signal of different order to microprocessor, thus the two-way choice of the program of realization.When this switch can be realized selection function, rollback was selected, and has saved select time greatly, has simplified operating performance, realized the general technique effect of rotary switch.
