The signal transmission ends changing unit is connected with wiring board by the SS end of upper and lower bonder.The most in the present embodiment,
Described bonder is seven to insert bonder.The operation principle of the present embodiment is consistent with above-described embodiment 1, at this not
Repeat the most one by one.
By arranging switch between load and mains supply, and make to switch on-off and be controlled by bowl cover,
In work process, when bowl cover departs from cup, then can cause switching off, i.e. load circuit disconnects, and now bears
It is loaded in no longer operation when bowl cover departs from, it is ensured that user's safety in use, also improves whole
The quality of food processor.
Cup and the electrical part on support it is communicated in by using upper and lower bonder to be used for, so that switch
It is directly arranged on cup, so that cup can directly act on switch, it is to avoid use connecting rod triggers
Machine driving, it is ensured that the reliability of switch triggering.Between switch and upper bonder, cabling cavity volume is set,
And the trough of fixed beam is set in cabling cavity volume so that food processor is safer.Use cup
Handle on body is as cabling cavity volume so that the simple in construction of food processor, easy to assembly.
The power circuit powered to low-voltage module is directly connected to mains supply, and load current detection is set
Circuit, is monitored the working condition of load at any time, when loaded work piece unusual fluctuation occurs or owing to bowl cover takes off
From and when quitting work, food processor can be pointed out according to setting sight or report to the police.Ensure that peace
On the premise of Quan so that food processor is more intelligent, easily facilitate the use of user.Simultaneously to load
The real-time monitoring of operating current, also allows for the governor circuit adjustment to bearing power so that load controls more
Refinement concrete, the function making food processor is abundanter.
Zero cross detection circuit or voltage detecting circuit are connected with mains supply by microswitch, work as fine motion
After switching off, while load quits work, main control chip also will be unable to zero cross signal or electricity be detected
Pressure signal, now main control chip arranges also dependent on predetermined sight and points out or report to the police.Especially borrow
With zero cross detection circuit, because zero cross signal is originally indispensable in the governor circuit of food processor
Part, is meeting outside original functional requirement, is being monitored load circuit again, it is ensured that safety
Under premise so that circuit is simpler.
Or the power circuit powered to low-voltage module is connected mains supply, when controlled also by described switch
After the switching off of bowl cover, then the whole Circuits System power-off of food processor.Food processor stops work
Make, it is ensured that food processor is safe and reliable when bowl cover departs from.
By arrange between cup and support bonder by the switch being arranged on cup and other components and parts with
The wiring board being arranged in support connects.And signal dress is set on cup and changes unit, changed by signal
At the signal that the signal supervisory instruments such as the temperature being located on cup, water level and spilling are detected by unit
After reason conversion, giving, by coupler transfer, the wiring board that is arranged in support, the most not only may insure that letter
Number accurate delivery, it is also possible to reducing the pin count of bonder, now bonder has only to six pins and i.e. can ensure that
Food processor safe and reliable.
It is emphasized that protection scope of the present invention is including but not limited to above-mentioned detailed description of the invention.Should
Point out, for a person skilled in the art, under the premise without departing from the principles of the invention, it is also possible to make
Going out some deformation and improvement, these also should be considered to belong to protection scope of the present invention.
