The<the first preferred embodiment >
As shown in Figure 1, the first preferred embodiment of food cooking machine safety device 100 of the present invention, be applicable to be electrically connected on an AC power, this AC power is for generation of an input electric power that is string ripple and interchange, and this food cooking machine safety device 100 comprises: an agitator 150, a motor 170, and a control module 130.
This agitator 150 is for stirring food.
This motor 170 receives a driving voltage to rotate this agitator 150.
This control module 130 comprises: a driver 3 and a phase controller 4.
This phase controller 4 has: a detecting unit 41, a subtrator 42, and a pi element PI.
The rotating speed of these detecting unit 41 these motors 170 of detecting is to obtain an actual speed.
Subtrator 42 is electrically connected on this detecting unit 41 to receive this actual speed, and receives a rotating speed of target, and carries out subtraction to obtain a speed discrepancy according to this rotating speed of target and this actual speed.
Pi element PI is electrically connected on this subtrator 42 to receive this speed discrepancy, and this speed discrepancy is carried out to the proportional integral computing to obtain one, is the phase place variation of non-linear change, and produces this triggering signal according to this phase place variation.
Further illustrate at this detailed practice that obtains this phase place variation: this pi element PI carries out normalization to obtain a normal value, as the formula (1) by this speed discrepancy:
Normal value=speed discrepancy/regular preset value ... formula (1)
It is (as follows that this pi element PI stores one first corresponding table, but be not limited to following numeral), and tabled look-up to obtain the value of tabling look-up according to this normal value from this first corresponding table, each self-corresponding value of tabling look-up of a plurality of different normal values of this first corresponding table record, and the described value of tabling look-up increases progressively amplitude and is greater than normal value and increases progressively amplitude, furthermore, the curve that increases progressively of this value of tabling look-up is to be non-linear and slope for just.

The<the second preferred embodiment >
As shown in Figure 4, the second preferred embodiment 100 of food cooking machine safety device 100 of the present invention comprises a rotating speed detecting unit 110, a temperature detecting unit 120, and one controls module 130.For convenience of explaining, more illustrate the work package (Workpiece) of food cooking machine safety device 100 effect of bestowing in figure, that is container 201 and agitator 202; In other words, food cooking machine safety device 100 can only comprise rotating speed detecting unit 110, temperature detecting unit 120 and control module 130 in definition, the three is not as long as its mutual start relation, as described in following embodiment, breaks away from teaching scope of the present invention.In addition, this agitator 202 can be a cutter.
Brought forward is described, and rotating speed detecting unit 110 is the rotating speed of the agitator 202 for detecting container 201; 120 of temperature detecting units are for detecting the temperature of container 201.Control module 130 in the rotating speed 111 of agitator 202 lower than a safe speed of rotation preset value, and the temperature 121 of container 201 controls the rotating speed of agitator 202 during higher than a safe temperature preset value, makes it be no more than a splash rotating speed critical value.
For instance, the temperature 121 of supposing container 201 for example is, below safe temperature preset value (60 degree Celsius),, even if the rotating speed 111 of agitator 202 increases severely on time shaft, produces splash, also is unlikely to cause burn and scald; So control the rotating speed 111 that module 130 does not need to limit agitator 202, make it for example, lower than splash rotating speed critical value (per minute 1000 turn).On the other hand, suppose that the temperature 121 of container 201 for example, higher than safe temperature preset value (80 degree Celsius), if now the rotating speed 111 of agitator 202 is for example, higher than safe speed of rotation preset value (per minute 50 turn), for example, even if the rotating speed of agitator 202 111 is pulled up to the high rotating speed (per minute 2000 turn) over splash rotating speed critical value, also do not produce splash, reason is that the coefficient of kinetic friction perseverance of material is much smaller than confficient of static friction.
Therefore, actuating opportunity of the food cooking machine safety device 100 of present embodiment for the temperature 121 when container 201 for example, higher than safe temperature preset value (80 degree Celsius), and the rotating speed 111 of agitator 202 for example, lower than safe speed of rotation preset value (per minute 50 turn), for example, if now the user assigns instruction and the rotating speed of agitator 202 111 will be promoted to the high rotating speed (per minute 2000 turn) over splash rotating speed critical value, the food cooking machine safety device 100 of present embodiment can be forced the rotating speed of agitator 202 111 for example is controlled at, under splash rotating speed critical value (per minute 1000 turn) because condition meets.
Whereby, can avoid the material of container 201 interior high temperature, because of unexpected stressed stirring splash.Particularly, the design of above-mentioned all parameters is considered as follows:
Safe speed of rotation preset value and splash rotating speed critical value spacing can design the damped coefficient that is proportional to agitator; In other words, the damped coefficient of agitator 202 is less, and the transient response time is shorter, draws high the high-revolving time from the slow-speed of revolution faster, stressed larger in the 201 inner fluid material unit interval of container, more easily causes splash; Therefore, the rotating speed difference between safe speed of rotation preset value and splash rotating speed critical value must corresponding shortening, and for example the safe speed of rotation preset value still turns for per minute 50, but splash rotating speed critical value turns and is down to per minute 500 and turns from former setting per minute 1000.
In like manner, the safe temperature preset value also can design the damped coefficient that is proportional to agitator 202; From the above, the damped coefficient of agitator 202 is larger, more is difficult for causing splash, so can mate larger safe temperature preset value.For instance, if establish the food cooking machine safety device 100 that two mixers all are equipped with present embodiment; The damped coefficient of the agitator 202 of First mixer is larger, and it is longer that the rotating speed of agitator 202 draws high the time, stressed less in the flowing material unit interval, so be difficult for splash, can set higher safe temperature preset value (for example 85 degree Celsius).On the contrary, the damped coefficient of the agitator 202 of second mixer is less, and it is shorter that the rotating speed of agitator 202 draws high the time, stressed larger in the flowing material unit interval, so easier splash, thereby should set lower safe temperature preset value (for example 75 degree Celsius).Generally speaking, this measure is to provide the free degree in mixer producer design.
On the other hand, the safe temperature preset value also can be designed to be inversely proportional to the viscosity of the content that container 201 takes up; That is, when the liquid object stirred is more sticky, the burn and scald produced during its splash is also more serious, so should mate less safe temperature preset value.For instance, in design, because the viscosity of thick soup is larger, the burn and scald produced during splash is more serious for hot tea agitator and thick soup agitator, so should help with relatively low safe temperature preset value.
As shown in 5 figure, it is the functional block diagram of the 3rd preferred embodiment of food cooking machine safety device of the present invention.In Fig. 5, food cooking machine safety device 100 also can comprise rotating speed detecting unit 110, temperature detecting unit 120, control module 130, container 140, agitator 150, speed setting interface 160 and motor 170 in definition.In other words, container 140, agitator 150, speed setting interface 160 and motor 170 can be the environment assembly (Environment element) of the food cooking machine safety device 100 of present embodiment.Further description is as follows: rotating speed detecting unit 110 can be the light interruptible sensor, directly detects the rotating speed of agitator 150; It also can be the size of current detector, directly detects the size of the electric current of motor 170, i.e. known its rotating speed.For instance, the size of current detector can realize with the measurement assembly of direct-type or indirect type, and the latter is helmholtz coil (Helmholtz coil) for example.Speed setting interface 160 is to give and control module 130 for input speed setting value 161, controls module 130 and just can optionally select the rotating speed of agitator 150 is raised to speed setting value 161, or be defined in as previously mentioned in splash rotating speed critical value.On the other hand, motor 170 can be motor such as stepper motor or linear motor.
As shown in Figure 6, be the logical circuitry of the control module 130 of the present invention's the second preferred embodiment; For convenience of explaining, more illustrate speed setting interface 160 and motor 170 in figure.Controlling the logic circuit of module 130 can realize by the mode of software, firmware or hardware; The logical circuitry of the control module 130 that Fig. 6 illustrates, be only a suitable example, but not be limitr.In Fig. 6, judge formula: whether the safe speed of rotation preset value is greater than the current rotating speed of agitator 150, and judges formula: whether the temperature of container 140 is greater than the safe temperature preset value, and both,, after the logical AND gate computing, import selector by result; If two judgement formulas all are satisfied, logical AND gate output 1, make selector select splash rotating speed critical value to carry out CD-ROM drive motor 170.On the contrary, if arbitrary in two judgement formulas, be false, logical AND gate output 0, and the speed setting value that makes selector select the speed setting interface to provide carrys out CD-ROM drive motor 170.Certainly, rotating speed detecting unit 110 can periodically operate with setting with temperature detecting unit 120; So control order that module 130 assigns and be also and look at any time the change of actual state and adjust.
In sum, above-described embodiment has the following advantages:
1. reaction is very fast, and utilizing tables look-up increases the variation of rotating speed with weighted value, so when load change, can immediate response.
2. when motor 170 operates in low speed, by this zero load phase value, come the strangulation driving voltage to maintain motor rotary speed, if be transformed into load condition by Light Condition, the motor rotary speed change is stable and level and smooth.
3. avoid the splash that scatters of the liquid object of high temperature, solve the danger that existing mixer may cause.
4. provide various supporting design mechanism, in the security settings mode of the various existing mixers that adapt to different demands.
Only as described above, it is only preferred embodiment of the present invention, when not limiting scope of the invention process with this, the simple equivalence of generally doing according to the claims in the present invention and invention description content changes and modifies, and all still remains within the scope of the patent.
