Description
Technical field
The present invention relates to a kind of working state control method of the equipment that rotary switch is sensed with noncontact.
Background technology
It is particularly in household electrical appliance in many electronic equipments, often carries out parameter setting and behaviour using rotary switch
Make.The rotary switch of physical connection, such as potentiometer type rotary switch, rod failure coding type rotary switch, in use can be because of machinery
The effect of attrition service life of structure, while the rotary switch of physical connection is when in use due to needing the panel in electric equipment
Upper perforate, destroys the integrality and sealing of device housings, causes being weakened significantly by force intensity for panel, also results in equipment
Inside outside pollutant access arrangement, the parts and circuit to device interior constitute pollution and destroy, while in certain journey
Also the cleaning of panel is hampered on degree.Therefore, the noncontact sensing rotary switch that recent years occurs is used increasingly,
Noncontact sensing knob includes two parts --- and noncontact senses knob and knob sensor circuit, and noncontact sensing knob is placed on
Guidance panel outer surface fixed position, and knob induced electricity is then arranged on guidance panel inner side, noncontact sensing knob and knob
Sensor circuit is not contacted, while noncontact sensing knob can arbitrarily be moved or removed.This noncontact sensing knob is somebody's turn to do to using
The product of rotary switch brings great technology sense and easy to operate.But not fixing for noncontact sensing knob, removing
In the case of operation there is certain potential safety hazard.Such as the children in family, curious is felt to noncontact sensing knob and is removed non-
Contact induction knob, and kitchen range are accidentally triggered during removing and is opened fire, it is ignorant due to household after kitchen range are opened fire,
Can there is the hidden danger harm user security of fire in kitchen range burned for long time.
Certainly, can additionally add on the equipment that rotary switch is sensed using noncontact in some considerate products
Plus a virgin lock button, child is locked when using complete equipment, and child is locked again open when in use.Although this mode energy
Largely solve potential safety hazard, but increased cost while bringing user brings more use step, so as to lower
The ease for use of equipment.

Improve again, in the case of b, if equipment removes the time more than first pre- because noncontact senses knob from specified location
If the time cause enter off-mode after, and if detect noncontact sensing knob be taken back to specified location, equipment is automatic
Start.
Improve again, when equipment is in holding state, if detect noncontact sensing knob is in specified location not all the time
It is removed, and the time is more than the second predetermined threshold value, then the current idle state of locking device；If detecting noncontact sensing rotation
Button is not removed all the time in specified location, and the time is more than the 3rd predetermined threshold value, then equipment is entered into off-mode；Described
Three predetermined threshold values are more than or equal to the second predetermined threshold value.
Improve again, if equipment is because noncontact senses, and knob is not removed all the time in specified location and the time is more than second
Standby lock-out state caused by predetermined threshold value, and if detect noncontact sensing knob remove from specified location after put again
Return, equipment releases current idle lock-out state, into holding state；If equipment is because noncontact sensing knob is all the time in specified
Position is not removed and the time is more than off-mode caused by the 3rd predetermined threshold value, and if detect noncontact sense knob from
Specified location is put back into again after removing, equipment Auto Power On.
Improve again, noncontact sensing knob detection part is set on equipment, noncontact senses the inspection of knob detection part
Survey scope and be the specified location that noncontact senses knob；Noncontact is sensed into the main control circuit of knob detection part and equipment
Plate connects, and whether main control board judges noncontact sensing knob according to the detection signal of noncontact sensing knob detection part
Remove from specified location.
The noncontact sensing knob detection part can be the magnitude of field intensity that can detect noncontact sensing knob
Linear hall element, the main control board judges that noncontact senses knob according to the size of linear hall element output signal
Whether remove from specified location.
Noncontact sensing knob detection part can also be to detect that what the magnetic field of noncontact sensing knob whether there is opens
Close the presence or absence of Hall element, described main control board root switch Hall component output signal whether to judge noncontact sensing knob
Remove from specified location.
Compared with prior art, it is an advantage of the current invention that：Knob can be sensed from equipment specific bit by detection noncontact
Put after removing, equipment is locked, is unlocked and power-off operation, it is safe, it is easy-to-use.
