The embodiment of the application provides a method for detecting material quantity of a food processor, and as shown in fig. 1, the method may include steps S101 to S104:
s101, adding water with a preset volume into a grinding cavity of the food processor;
s102, after a grinding motor of the food processor starts to work, enabling the grinding cavity to enter a closed state;
s103, detecting the temperature in the grinding cavity through a preset temperature detection device;
s104, determining the quantity of the materials in the grinding cavity according to the relationship 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 material amount in the grinding cavity is the set standard material amount.
In an exemplary embodiment of the present application, the determining the amount of the material in the grinding chamber according to the magnitude relationship 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 material amount in the grinding cavity is large;
and when the temperature in the grinding cavity is lower than the standard temperature, determining that the material amount in the grinding cavity is less.
In an exemplary embodiment of the present application, as shown in fig. 2, the food processor may include: the grinding machine 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 grinding the airtight and ventilative function in chamber.
In the exemplary embodiment of this application, during the slurrying, the water pump can be followed the water pump and gone into the water entering grinding chamber of fixed quantity (predetermineeing the capacity), when crushing motor during operation, locks the bowl cover through the ejector pin, realizes grinding chamber's airtight function. When the grinding cavity is closed, the grinding cavity is sealed to form a pressure container. 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 crushing motor is operated, the work done by the crushing motor under the standard material amount (load is R) can be divided into two parts W1 which is W1+ q 1. Wherein w1 is the kinetic energy of the rotation of the grinding motor, and q1 is the heat absorbed by the pulp when the grinding motor rotates to do work. When the grinding cavity is closed, 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 grinding cavity cannot be vaporized after absorbing the heat due to the closed cavity, so that the temperature is increased. According to the specific heat capacity formula, the temperature is T1 ═ q1/cm + T0, T0 is the temperature of the slurry before the grinding motor starts to work, c is the specific heat capacity of the slurry and air in the grinding cavity, and m is the total mass of the materials. When the amount of the materials is excessive, the load is increased, the work W2 of the grinding motor is W3+ W4, the power of the grinding motor is increased, namely, W2 is more than W1, W2 is more than W1, and q2 is more than q1, namely, the heat generated by the operation of the grinding motor is increased, the slurry temperature is T2, and the specific heat capacity formula shows that T2 is more than T1. Similarly, when the material amount is less, the power of the crushing motor during working is reduced, the heat generated by the crushing motor is reduced, and the pulp temperature T3 is less than T1. Therefore, the amount (quality 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 material is effectively identified through judging the pulp temperature in the pulping process.
In an exemplary embodiment of the present application, the method may further include:
before the crushing motor of the food processor starts to work, the grinding cavity is kept in a ventilation state, and water in the grinding cavity is boiled to exhaust air in the grinding cavity through water vapor.
In an exemplary embodiment of the present application, the detection phase of the scheme of the present embodiment may be divided into two parts:
1. the grinding cup is exhausted before the cup cover of the box.
2. The crushing motor works behind the cup cover to crush, and simultaneously, the material quantity is judged by a temperature or temperature slope method.
In the exemplary embodiment of the application, after the grinding chamber is sealed, the pressure of the gas in the chamber increases with the increase of the temperature, and when the component proportion (mainly the proportion of water vapor to air) of the gas is different, the pressure difference generated at the same temperature is large, so that the load change of the grinding motor caused by the gas pressure change is far larger than the load change caused by the material quantity, and the deviation of the identification result is large. This application embodiment scheme is through the mode that boils the water in the cavity before airtight, produces a large amount of vapor to the intracavity air is ground in the evacuation, makes airtight back only vapor exist in grinding the intracavity, and the pressure value uniformity that gas produced under the same temperature improves, has eliminated the influence of gas pressure to the testing result.
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 preset time length;
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, after the water in the grinding chamber is boiled, the small power boiling may be performed for T seconds while the heating power is adjusted according to the temperature change.
In the exemplary embodiment of the present application, to keep the liquid in a slightly boiling state, kP1 ═ P2+ P3, P1 is the input power of a heating module (e.g., a heating pipe), k is the heating coefficient, P2 is the power of water absorbing heat, P3 is the heat dissipation power, kP1T ═ cm Δ T + P3T is available, Δ T (temperature rise value of slurry) cannot rise when water boils, and the heat is completely converted into water vapor to be dissipated, that is, the larger P1 is, the more the boiling is. When P1 is less than P3, the water absorbs less heat and the temperature decreases. The water can be kept in a certain boiling state by setting a proper power, and the higher the temperature is, the larger the mass is, and the larger the P3 is, because the heat dissipation power of the water is related to the mass and the temperature of the water.
In an exemplary embodiment of the present application, the adjusting of the heating power according to the temperature variation may include:
increasing the heating power when the temperature within the grinding chamber begins to decrease for a first period of time; the first time length is less than the preset time length;
and when the temperature in the grinding chamber is kept constant 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/hectogram (i.e., 500mL liquid heating power is 200W), the heating is continued for 180s, the temperature is detected during the heating process, the heating power Δ P (10W/hectogram) may be increased when the temperature is decreased in the first time period ts (5< t <20), and the power may be restored to the initial set value when the temperature is maintained for the first time period ts (5< t < 20).
In the exemplary embodiment of the application, the liquid in the grinding cavity is continuously kept in a micro-boiling state, water vapor is generated to exhaust the liquid, and the gas pressure error is 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 chamber is sealed is taken as the initial temperature T0 for calculating the standard temperature.
In an exemplary embodiment of the present application, the initial temperature T0 used to calculate 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 can be seen from the specific heat capacity formula of the liquid, the heat Q is CM (T-T0), C is the specific heat capacity, M is the liquid mass, and when the selected capacity is constant, 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 different altitude and temperature sensor measurement errors. The highest temperature (such as boiling temperature) before the grinding cavity is sealed can be selected as a T0 value, and since the temperature is boiled in the early stage, T0 is consistent with the boiling point, and T0 are measured by the same temperature sensor, T-T0 can eliminate the measurement error of the temperature sensor and eliminate the influence of different boiling points at different altitudes.
In an exemplary embodiment of the present application, the method may further include: and when the control mode of the crushing motor is chopping control, performing equivalent conversion on the working time of the crushing motor at different chopping points of the crushing motor so as to enable the slurry to absorb the same heat when the crushing motor works at the different chopping points.
In the exemplary embodiment of the present application, the operation time lengths of the pulverizing motors at different chopping points in the flow can be equivalently converted.
In the exemplary embodiment of the application, the heat Q absorbed by the slurry in pulping is related to the working power and the working time of the crushing motor, the working power of the crushing motor is different under different voltage driving, and the generated heat Q is different. Because the electric grinding motor control mode adopted by the scheme of the embodiment can be chopping control, the heat quantity Q and the chopping point Ta (0 ═ can be generated<Ta<10 ms). When the chopping point of the pulverizing motor is Ta, the power P of the pulverizing motor ═ Ta ([ integral ] Ta, 0.01)]380sin200πt)2And Ra is the chopping angle of the motor, and Ra is the equivalent resistance of the crushing motor. The heat Q can be equivalently calculated as Q ═ k ([ Ta,0.01 ^ k ^ Q]380sin200πt)2And the/Ra t1 and t1 are the actual working time of the crushing motor. Q1 ═ k ([ 0,0.01 ])]380sin200πt)2T2 ═ jekt [ Ta,0.01 ] can be obtained since/Ra × t2]380sin200πt)2*t1/(∫[0,0.01]380sin200πt)2That is, 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 operation is improved through equivalent conversion of different power working time lengths 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 relationship between the temperature in the grinding chamber and the set standard temperature may further include:
determining the amount of the materials in the grinding cavity according to the size 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 sealed state and the material amount in the grinding cavity is the set standard material amount.
In an exemplary embodiment of the present application, the material amount may be judged by a difference between a rising slope of the slurry temperature and a standard material amount temperature rising slope.
In the exemplary embodiment of the application, the working step duration of the pulverizing motor with different powers in different stages is converted into the equivalent duration by the scheme. Every time when the equivalent working time interval of the grinding motor is T seconds, the temperature is sampled at the time and is Tn, the gradient of the temperature rise in the time interval T is Kn ═ Tn-T (N-1))/T, and the average value of N times of sampling can be taken as the final gradient, namely the final gradient K ═ K1+ K2 … Kn)/N. In this embodiment, t may be 60s, and N may be 60 (integer) of the total equivalent time length of the motor. The quantity of the material can be judged according to the difference between the temperature rise slope K after the pulping is closed and the temperature rise slope K0 under the standard material quantity. Namely, K is the calculated temperature gradient (K-K0) + G, G is the standard material amount of different volumes, and K is the conversion proportionality coefficient.
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 abnormal pulping is avoided.
In an exemplary embodiment of the present application, the method may further include: and calling different pulping flows 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 different pulping processes according to a difference between a comparison result of a temperature rising slope in the grinding chamber and a set standard temperature rising slope may include:
when K is less than or equal to 1.1K0, calling a standard pulping process; k is the temperature rising slope in the grinding cavity; k0 is the standard temperature rise slope;
when K is more than 1.1K0 and less than or equal to 1.3K0, on the basis of a standard pulping process, the waiting time of the working period of the crushing motor is prolonged, and the heating power is adjusted;
when K is more than 1.3K0 and less than or equal to 1.5K0, reducing the rotating speed of the crushing motor to 80 percent 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 more than 1.5K0, performing overload alarm.
In the exemplary embodiment of the application, the most direct influence of the 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 the long-time high temperature, and the damage of the motor is accelerated. The motor work waiting clearance is adjusted through detecting the load, thereby the motor heat dissipation time is increased and the motor temperature rise is effectively reduced, the mode is that the life-span of the product is prolonged through sacrificing the pulping time, but when the load reaches more than 1.5 times of standard materials, the purpose of temperature rise can not be satisfied through only prolonging the waiting time, therefore, the reliability is satisfied through sacrificing the crushing effect.
In the exemplary embodiment of the present application, when the load exceeds 2 times of the standard material, the pulping effect cannot be guaranteed and there is a safety risk, so an alarm is required to prompt the user.
In the exemplary embodiment of the present application, the multiple material deposition at the bottom of the grinding chamber may affect the heat transfer, and the excessive temperature may cause the bottom pasting, so the power reduction treatment of the heating power may prevent the rapid heat enrichment from the bottom pasting.
