The embodiment of the application provides a material amount detection method of a food processor, as shown in fig. 1, the method may include steps S101-S104:
s101, adding water with preset volume into a grinding cavity of the food processor;
s102, enabling the grinding cavity to enter a closed state after a grinding motor of the food processor starts to work;
s103, detecting the temperature in the grinding cavity through a preset temperature detection device;
s104, determining the amount of the materials in the grinding cavity according to the size relation between the temperature in the grinding cavity and the set standard temperature; the standard temperature is the internal temperature of the grinding cavity when the grinding cavity is in a sealed state and the amount of materials in the grinding cavity is the set standard amount of materials.
In an exemplary embodiment of the present application, the determining the amount of the material in the grinding chamber according to the magnitude relation between the temperature in the grinding chamber and the set standard temperature may include:
when the temperature in the grinding cavity is equal to the standard temperature, determining that the material amount in the grinding cavity is proper;
when the temperature in the grinding cavity is higher than the standard temperature, determining that the amount of materials in the grinding cavity is more;
and when the temperature in the grinding cavity is smaller than the standard temperature, determining that the material amount in the grinding cavity is smaller.
In an exemplary embodiment of the present application, as shown in fig. 2, the food processor may include: the grinding device comprises a water tank, a flow pump, a heating module, a grinding cavity, an MCU detection module, a cup cover, a temperature detection device and a grinding motor. Wherein, the bowl cover accessible gear motor control realizes the airtight and the ventilative function in grinding the chamber.
In the exemplary embodiment of the application, during pulping, the water pump can pump in fixed quantity (preset capacity) of water from the water tank to enter the grinding cavity, and when the grinding motor works, the cup cover is locked through the ejector rod, so that the sealing function of the grinding cavity is realized. When the grinding chamber is closed, the grinding chamber is sealed to form a pressure vessel. When the grinding cavity is ventilated, the grinding cavity is communicated with the outside, and the internal pressure and the external pressure are consistent. When the pulverizing motor is operated, work performed by the pulverizing motor at a standard material amount (load R) may be divided into two parts w1=w1+q1. Wherein w1 is the kinetic energy of the rotation of the crushing motor, and q1 is the heat absorbed by the slurry when the crushing motor rotates to do work. When the grinding cavity is sealed, the temperature of the slurry and the gas in the grinding cavity can be increased by the heat provided by the grinding motor, and the slurry and the gas in the cavity cannot be vaporized after absorbing the heat due to the sealing of the cavity, so that the temperature is increased. According to the specific heat capacity formula, the temperature is T1=q1/cm+T0 at the moment, T0 is the slurry temperature before the crushing motor starts working, c is the specific heat capacity of slurry and air in the grinding cavity, and m is the total mass of materials. When the material quantity is excessive, the load becomes larger, at the moment, the work W2=w3+w4 of the crushing motor is larger, namely, the power of the crushing motor becomes larger, namely, W2 is larger than W1, q2 is larger than q1, namely, the heat produced by the working of the crushing motor is larger, at the moment, the slurry temperature is T2, and the fact that T2 is larger than T1 is known by a specific heat capacity formula. Similarly, when the amount of the materials is small, the power of the crushing motor during operation is reduced, the heat produced by the crushing motor is reduced, and the slurry temperature T3 is less than T1. So that the quantity (mass and/or volume) of the pulping material can be judged by detecting the temperature of the pulp.
In the exemplary embodiment of the application, the condition of more or less materials is effectively identified through judging the slurry temperature in the pulping process.
In an exemplary embodiment of the present application, the method may further include:
before the grinding motor of the food processor starts to work, the grinding cavity is kept in an air-permeable state, and water in the grinding cavity is boiled so as to exhaust air in the grinding cavity through water vapor.
In an exemplary embodiment of the present application, the detection phase of the embodiment may be divided into two parts:
1. and (5) carrying out exhaust treatment on the grinding cup in front of the box cup cover.
2. The crushing motor works for crushing after the box cup cover, and the material quantity is judged by a temperature magnitude or temperature slope method.
In the exemplary embodiment of the application, after the grinding cavity is sealed, the pressure of the gas in the cavity increases along with the increase of the temperature, and when the component proportions (mainly the water vapor and the air proportion) of the gas are different, the pressure difference generated at the same temperature is larger, so that the load change of the grinding motor caused by the pressure change of the gas is far greater than the load change caused by the material quantity, and the deviation of the identification result is larger. According to the scheme, a large amount of water vapor is generated by boiling water in the cavity before sealing, so that air in the grinding cavity is emptied, only the water vapor exists in the grinding cavity after sealing, the consistency of pressure values generated by gas at the same temperature is improved, and the influence of gas pressure on a detection result is eliminated.
In an exemplary embodiment of the present application, the method may further include:
after the water in the grinding cavity is boiled, reducing the heating power to continue heating, and keeping the heating power for a preset period of time;
and detecting the temperature in the grinding cavity in the heating process, and adjusting the heating power according to the temperature change.
In an exemplary embodiment of the present application, a low power boil-off holding for T seconds may be performed after the water in the grinding chamber is boiled, while the heating power is adjusted according to the temperature change.
In the exemplary embodiment of the present application, to keep the liquid in the micro-boiling state, it may be satisfied that kp1=p2+p3, P1 is the input power of the heating module (such as a heating pipe), k is the heating coefficient, P2 is the power of the water absorbing heat, P3 is the heat dissipation power, kp1t=cm Δt+p3t can be obtained, Δt (the temperature rise value of the slurry) cannot rise when the water boils, and the heat is completely converted into vapor for emission, i.e., the larger P1, the more the boiling is. When P1 is smaller than P3, the heat of water absorption decreases and the temperature decreases. The water can be kept in a certain boiling state by setting proper power, and meanwhile, as the heat dissipation power of the water is related to the quality and the temperature of the water, the higher the temperature is, the larger the quality is, and the larger the P3 is.
In an exemplary embodiment of the present application, the adjusting the heating power according to the temperature change may include:
increasing the heating power when the temperature in the grinding chamber begins to decrease during a first period of time; the first time period is smaller than the preset time period;
and when the temperature in the grinding cavity is kept unchanged in the first time period, the heating power is restored to the initial set value.
In an exemplary embodiment of the present application, the micro-boiling power may be 40W/hundred grams (i.e., the heating power of 500mL of liquid is 200W), the heating may be continued for 180s, the temperature may be detected during the heating process, the heating power Δp may be increased (10W/hundred grams) when the temperature decreases within the first period of time ts (5 < t < 20), and the power may be restored to the initial set value when the temperature remains unchanged throughout the first period of time ts (5 < t < 20).
In the exemplary embodiment of the application, the liquid in the grinding cavity is kept in a micro-boiling state continuously, so that water vapor is generated to empty the liquid, and gas pressure errors are reduced. Meanwhile, the whole machine is changed from a cold state to a hot state, and the temperature difference caused by heat dissipation of the cold and hot pot is reduced.
In an exemplary embodiment of the present application, the method may further include: the boiling temperature before the grinding cavity is sealed is taken as an initial temperature T0 for calculating the standard temperature.
In an exemplary embodiment of the present application, the initial temperature T0 for calculating the standard temperature may be calibrated with the temperature after the grinding chamber is sealed as a calibration value.
In the exemplary embodiment of the present application, as known from the specific heat capacity formula of the liquid, heat q=cm (T-T0), C is the specific heat capacity, M is the liquid mass, and when the selected capacity is fixed, the two values are fixed values. T is the temperature of the liquid after absorbing heat, and T0 is the temperature of the liquid before absorbing heat. The value of T0 is affected by the measurement errors of the various altitudes and temperature sensors. In the scheme of the embodiment, the highest temperature (such as boiling temperature) before the sealing of the grinding cavity can be selected as a value T0, and because the grinding cavity is boiled in the earlier stage, the T0 is consistent with the boiling point, and meanwhile, the T and the T0 are measured by the same temperature sensor, so that the T-T0 can eliminate the measurement error of the temperature sensor and eliminate the influence of different altitudes and different boiling points.
In an exemplary embodiment of the present application, the method may further include: when the control mode of the crushing motor is chopping control, equivalent conversion is carried out on the working time length of the crushing motor at different chopping points of the crushing motor, so that the slurry absorbs the same heat when the crushing motor works at different chopping points.
In the exemplary embodiment of the application, the equivalent conversion can be performed on the working time lengths of the crushing motors with different chopping points in the process.
In the exemplary embodiment of the application, the heat Q absorbed by the slurry during pulping is related to the working power and the working time of the crushing motor, the working power of the crushing motor driven by different voltages is different, and the generated heat Q is also different. Since the electric pulverizing motor control method adopted in the embodiment can be chopper control, the heat quantity Q and the chopping point Ta (0=)<Ta<=10 ms). When the chopping point of the operation of the pulverizing motor is Ta, the power P= (≡ [ Ta, 0.01)]380sin200πt) 2 Ra, ta is the chopping angle and Ra is the equivalent resistance of the crushing motor. The heat Q can be equivalently calculated as q=k (+ [ Ta, 0.01)]380sin200πt) 2 Ra is t1, t1 is the actual working time of the pulverizing motor. Q1=k (≡ 0,0.01)]380sin200πt) 2 Ra t2, so t2= (≡ [ Ta, 0.01)]380sin200πt) 2 *t1/(∫[0,0.01]380sin200πt) 2 I.e. the small power operation t1 seconds of the crushing motor can be equivalent to the full power operation t2 seconds.
In the exemplary embodiment of the application, the accuracy of temperature detection and temperature slope calculation is improved through equivalent conversion of the working time lengths of different powers of the crushing motor.
In an exemplary embodiment of the present application, the determining the amount of the material in the grinding chamber according to the magnitude relation between the temperature in the grinding chamber and the set standard temperature may further include:
determining the amount of the material in the grinding cavity according to the magnitude relation between the temperature rising slope in the grinding cavity and the set standard temperature rising slope; the standard temperature rising slope is the internal temperature rising slope of the grinding cavity when the grinding cavity is in a sealing state and the material quantity in the grinding cavity is the set standard material quantity.
In an exemplary embodiment of the present application, the material amount may be determined by the difference between the rising slope of the slurry temperature and the rising slope of the standard material amount temperature.
In the exemplary embodiment of the application, the time length of the working steps of the crushing motor with different power at different stages is converted into the equivalent time length through the scheme. When the equivalent working time interval of the crushing motor is T seconds, sampling the temperature Tn, wherein the slope of temperature rise is Kn= (Tn-T (N-1))/T in the T time interval, and the average value of N times of sampling can be taken as the final slope, namely the final slope K= (K1+K … Kn)/N. The scheme of the embodiment can take t=60s, and N=total equivalent duration of motor operation/60 (taking an integer). And judging the quantity of the materials by the difference between the temperature rise slope K after the pulping is closed and the temperature rise slope K0 under the standard material quantity. I.e. the mass = K (K-K0) +g, K being the calculated temperature slope, G being the standard mass of different capacities, K being the conversion scaling factor.
In the exemplary embodiment of the application, the material quantity at the moment is judged according to the rising slope of the slurry, so that different processing flows are executed, and pulping abnormality is avoided.
In an exemplary embodiment of the present application, the method may further include: and calling different pulping processes according to different comparison results of the temperature rising slope in the grinding cavity and the set standard temperature rising slope.
In an exemplary embodiment of the present application, the invoking the different pulping process may include:
when K is less than or equal to 1.1K0, a standard pulping process is called; k is the temperature rising slope in the grinding cavity; k0 is the standard temperature rising slope;
when 1.1K0 is more than K and less than or equal to 1.3K0, on the basis of a standard pulping process, prolonging the waiting time of the crushing motor during the working period and adjusting the heating power;
when 1.3K0 is more than K and less than or equal to 1.5K0, reducing the rotating speed of the crushing motor to 80% of the preset standard crushing rotating speed, prolonging the waiting time of the working period of the crushing motor, and adjusting the heating power;
and when K is larger than 1.5K0, carrying out overload alarm.
In the exemplary embodiment of the application, the most direct influence of overload is that the working current of the motor is increased, the temperature rise of the motor is further influenced, the reliability of the motor is reduced due to long-time high temperature, and the motor is accelerated to be damaged. The motor working waiting gap is adjusted by detecting the load, the motor heat dissipation time is increased, and therefore the motor temperature rise is effectively reduced.
In the exemplary embodiment of the present application, when the load exceeds 2 times of the standard material, the pulping effect cannot be ensured and there is a safety risk, so that an alarm is required to prompt the user.
In the exemplary embodiment of the application, multiple material deposits at the bottom of the grinding cavity can affect heat transfer, and excessive temperatures can cause paste bottom, so that heat can be prevented from being rapidly enriched by performing power reduction treatment on heating power.
