Cup 2, anti-overflow device 3 and heating device 4, wherein the cooking machine further includes water level sensor 5, and the anti-overflow controlling means are extremely
Less include overflow value read step: main control chip (not shown), which reads the overflow value that anti-overflow device 3 detects and is used as, overflows
A reference value A, the spilling a reference value A are the detected value of anti-overflow device 3 before heating device 4 is begun to warm up；Aligning step: the water level
Sensor 5 detects the conductivity of slurries in stirring cup 2, and main control chip overflows trigger value C according to the Conductivity Calculation of slurries and deposits
The conductivity of storage, different slurries is different, overflows trigger value C such that regardless of the slurry in stirring cup 2 according to the Conductivity Calculation of slurries
It is also different that liquid overflows trigger value C when containing different materials, and is all closest to the spilling trigger value of such slurries, makes
It is anti-overflow more accurate；Anti-overflow judgment step: during heating, main control chip read in real time current overflow value B and by its with overflow
A reference value A, which calculate, out obtains calculated value, and the calculated value is compared to judge whether to do to overflow with trigger value C is overflowed
Processing.
" slurries " refer to the mixture of water and material, and the state of material can be not pulverized, are also possible to be crushed
Knife crushes later.
Further, in aligning step, the slurries conductivity of 5 real-time measurement of water level sensor is M, the master control
Chip carries out real time correction and update to C according to M.The C is directly proportional to M, C=α × M, and wherein α is correction coefficient, α >=1.Slurry
Conductivity becomes larger liquid after the heating, and with after slurries are pulverized particle increase conductivity also and will increase, overflow trigger value C with
The variation of conductivity and increase accordingly, make to overflow trigger value C and be adjusted according to the state of current slurries, improved anti-overflow reliable
Property.Slurries conductivity M is true in the stirring cup 2 that water level sensor 5 measures before the correction coefficient alpha is started to work by heating device 4
It is fixed, as M < 50, α=1；As M >=50, α > 1.That is, its spilling trigger value of the slurries low to conductivity will subtract
It is small, it prevents from not triggering generation spilling；It overflows increasing for trigger value to the slurries high for conductivity, prevents false triggering from causing to boil
It is not yet done.
In the present invention, the slurry liquid contacts due to water level sensor 5 directly and in stirring cup 2, can detecte slurry
The actual conductivity of liquid overflows trigger value C by the actual conductivity that water level sensor 5 detects come real time correction, so that anti-overflow
Generation that is relatively reliable, reducing false triggering, do not trigger phenomenon.Moreover, making the spilling trigger value obtained by Conductivity Calculation more
Add the type and machining state suitable for current slurries, the slurries more for electrolyte, such as fish soup, thick soup, overflows touching
Hair value C wants larger, the slurries less for electrolyte, such as rice paste, and it is smaller to overflow trigger value C.Moreover, with object
Material is pulverized, heating degree is different, and the electrolyte content in slurries can also change, and directly be connect by water level sensor 5
The conductivity of touching measurement slurries improves anti-overflow adaptive to calculation overflow trigger value C and carry out real time correction and update
Property, make anti-overflow relatively reliable.
In anti-overflow judgment step, as | A-B | > C and after duration T, the main control chip sentences section to overflow and controlling
Refrigerating/heating apparatus 4 stops working, and current overflow value B is the overflow value at the current time of 3 real-time measurement of anti-overflow device.And 400ms
≤ T≤600ms, making the benefit of T within the set range is to avoid stirring juice in crushing process and stick on anti-overflow device 3 to be judged to
It is anti-overflow for breaking, and prevents from judging by accident；It is still remained as T < 400ms and is mistaken for the case where overflowing；As T > 600ms, the time is too long,
It is possible that spillover.In the present embodiment, T=500ms.
In the course of work of heating device 4, in overflowing read step, main control chip overflows to 3 detection of anti-overflow device
Value, which is filtered, out judges whether it is interference signal, is then updated to spilling a reference value A if not interference signal, otherwise
It does not update.I.e. during heating, the overflow value of real-time detection is transferred to main control chip by anti-overflow device 3, when anti-overflow device 3 is examined
When the spilling value signal of survey generates mutation, main control chip can be filtered the jump signal, judge the jump signal whether be
Interference signal is not updated spilling a reference value A then if it is interference signal, will then overflow benchmark if not interference signal
Value A is updated as the overflow value.During heating, vapor can be attached to the surface of anti-overflow device 3, make anti-overflow device 3
Deviation is generated to the measurement for overflowing a reference value A, in the cooking machine course of work, overflowing a reference value A is overflowing for the measurement of anti-overflow device 3
It is worth out, with the progress for crushing, heating, the overflow value that anti-overflow device 3 measures can generate variation, and overflowing a reference value A can also follow
Variation is not updated spilling a reference value A when the overflow value that anti-overflow device 3 measures is slowly varying, only larger dash forward is occurring
It is just updated when change, keeps control program simpler, while excluding adhesion on anti-overflow device 3 has slurries to generate false excessive show
As making anti-overflow more accurate and reliable.In this example, it is filtered and is sentenced using detected value of the dynamic difference algorithm to anti-overflow device 3
Whether disconnected be interference signal, and interference signal is the value that anti-overflow device detects when adhesion has slurries on anti-overflow device 3.
A setting value built in the main control chip, in overflowing read step, main control chip reads what anti-overflow device 3 detected
Overflow value judges whether anti-overflow device 3 is contaminated compared with setting value as spilling a reference value A, and by spilling a reference value A,
It alarms if anti-overflow device 3 is contaminated, works on if anti-overflow device 3 is not contaminated.On the other hand, can also judge
Whether anti-overflow device 3 damages, and guarantees anti-overflow reliability.When especially machine just powers on, anti-overflow device 3 will do it measurement simultaneously
Signal is transmitted a main control chip to be compared with the setting value, to judge anti-overflow device 3 either with or without being contaminated, if dirty
Dye, machine can not work normally, then user needs to clean anti-overflow device 3, if anti-overflow device 3 is contaminated, anti-overflow dress
Set value that 3 measure will very little, judge that anti-overflow device 3 is either with or without dirty after machine powers on by way of built-in setting value
It is relatively reliable, accurate to contaminate.
It should be understood that main control chip will overflow a reference value A and the spilling trigger value C ratio after the completion of aligning step
Compared with to judge whether anti-overflow device 3 is contaminated.After the completion of crushing knife 7 is to the crushing material in stirring cup 2, in crushing knife 7
Centrifugal force effect under, slurries can splash on anti-overflow device 3, before the work of heating device 4, by will be in overflow value read step
