Example one
A method of material detection for a food processor, the food processor comprising: a water tank and a grinding chamber, the food processor may further comprise: the water inlet control device is used for controlling the water injection amount of the water tank to the crushing cavity; a plurality of liquid level detection devices which are respectively used for detecting different liquid levels are arranged in the crushing cavity; the food processor also comprises an operation panel, and the operation panel is provided with a selection key for the food processing function and a selection key for the processing capacity; as shown in FIG. 1, the method may include steps S11-S13:

s12, sequentially detecting the water injection amount between two adjacent liquid levels within one or more corresponding liquid level ranges contained in the processing capacity, and judging the material amount corresponding to the material positioned between the two adjacent liquid levels in the crushing cavity according to the water injection amount between the two adjacent liquid levels and the liquid level difference between the two adjacent liquid levels;
and S13, accumulating the material amount corresponding to the material between any two adjacent liquid levels, and judging whether the accumulated material amount reaches the target material amount when the total water injection amount reaches the target water amount.
In an embodiment of the present invention, the above embodiment may be applied to an unmanned hands-free food processor, and the food processor may include: the water inlet control device is used for controlling the water injection amount of the water tank into the crushing cavity; a plurality of liquid level detection devices respectively used for detecting different liquid levels can be arranged in the crushing cavity; the food processor also comprises an operation panel, and the operation panel can be provided with a selection key for food processing function and a selection key for processing capacity; the operation panel may also have a display function of processing data.
In the embodiment of the invention, a common household food processor (such as a soymilk machine) generally needs a user to add water and materials by himself, particularly, the water adding process is carried out through a water level line to carry out fuzzy judgment, the water level line generally comprises a lower water level line, a standard water level line and an upper water level line scale, and the user is difficult to judge the specific pulping capacity unless an electronic scale or a standard container is additionally arranged for accurate measurement. According to the embodiment of the invention, the target material quantity and the target water quantity required by current food processing can be determined according to the food processing function selected by the user and the required processing capacity, so that the process of calculating the ratio of the material to the water by the user is omitted, and the target material quantity and the target water quantity which are obtained are more accurate and reasonable. In addition, the food processor is provided with the water tank and the water inlet control device, so that water can be gradually added into the crushing cavity according to the calculated target water amount, and the accuracy of the water adding amount is ensured.
Alternatively, as shown in fig. 2, determining the target material amount and the target water amount required for the current food processing according to the food processing function selected by the user and the required processing capacity may include S21-S22:

In the embodiment of the present invention, the mapping table may be set in advance through multiple tests or empirical values to determine different processing capacities corresponding to different food processing functions, and target material amounts and target water amounts corresponding to different processing capacities. Therefore, after the user selects the food processing function and the required processing capacity, the mapping table can be directly called to determine the target material quantity and the target water quantity required by the current food processing, and the scheme is simple and easy to implement.
In addition, in the embodiment of the invention, as the degree of intellectualization and automation of the food processor is higher and higher, a user can think that the machine can process everything subconsciously, and the probability that the user forgets to put in the material is increased, so that whether the material is put in or not is necessarily detected to evaluate whether the material is put in or not and remind the user in time; the material detection method comprises the following steps: when the difference capacity between two liquid level detection devices is exactly equal to the water injection amount, the situation that the liquid completely passes through the materials can be judged, if the water injection amount is smaller than the difference capacity between the two liquid level detection devices, the existence of the materials between the two liquid level detection devices is indicated, therefore, the material amount of the materials between the two liquid level detection devices can be obtained by calculating the difference between the difference capacity between the two liquid level detection devices and the water injection amount, further, the detected material amounts in each step are gradually accumulated, whether the accumulated material amount is the pre-calculated target material amount or not is finally counted, the automatic detection of the material adding process is realized, the accuracy of material adding and the added material amount is ensured, the working performance of the food processing machine is improved, and the user experience is improved.
In the embodiment of the invention, the material detection method is based on the consideration that generally added materials cannot be completely and flatly paved in the crushing cavity, generally are conically accumulated at the bottom of the crushing cavity, or water can disperse the materials in the process of adding water, and the materials can be dispersed in the water along with the increase of the water level, so that a part of the materials can exist among a plurality of liquid level detection devices. Therefore, the material amount (mainly referred to as volume) corresponding to the material stacked or dispersed between every two liquid level detection devices can be detected respectively, and finally, the total material volume added into the crushing cavity is obtained by accumulating the material amount stacked or dispersed between every two liquid level detection devices, and the total mass of the added material can be further calculated according to the total volume, the density of the material and a mass calculation formula.
In the examples of the present invention, the above-described embodiment schemes are illustrated below by specific examples:
1. when a user selects a food processing function A and a processing capacity M (such as 800mL), the food processing machine starts to work, and a pulping process corresponding to the function A is called;
2. in the water filling stage, the target water amount is M- Δ L (Δ L is a target material amount, such as 200mL), the water is continuously filled to a preset first liquid level detection device (the capacity corresponding to the first liquid level detection device is L1, such as 250mL), the pump water amount Lm1 (such as 100mL) at the time is recorded, Δ L1 (the material amount existing between the bottom of the crushing cavity and the first liquid level detection device) is calculated, the target water amount is L1-Lm1 is L1-100 mL, such as 250mL-100mL, such as 150mL, if Δ L1 is 0, it can be determined that the user does not place the material, and the user is warned to put the material; if the delta L1 is less than 0, the water leakage of the crushing cavity or the water inlet pipeline is indicated, and fault alarm can be performed; if Δ L1 is equal to Δ L, it indicates that the target material amount is present between the bottom of the crushing cavity and the first liquid level detection device, and at this time, water is continuously injected until the required volume (i.e., the target water amount) is reached; if Δ L1 is greater than 0 and less than Δ L, it may be determined that there is a material amount between the bottom of the pulverization chamber and the first liquid level detection device, and the material amount is less than the target material amount, which indicates that there may be only a part of material between the bottom of the pulverization chamber and the first liquid level detection device, then water may be continuously injected to the second liquid level detection device (the corresponding capacity of the second liquid level detection device is L2, e.g. 350mL), the pump water amount at this time (the total pump water amount counted by the flow meter of the water pump) is Lm2 (e.g. 150mL), Δ L2 (the material amount existing between the first liquid level detection device and the second liquid level detection device) at this time is calculated (L2-L1) - (Lm2-Lm1) (350-, the alarm can remind the user to add the residual materials; if the delta L1 is less than 0, the water leakage of the crushing cavity or the water inlet pipeline is indicated, and fault alarm can be performed; if the delta L2 is more than 0 and less than delta L-delta L1, the situation that the material quantity exists between the first liquid level detection device and the second liquid level detection device can be judged, and the material quantity is smaller than the difference value between the target material quantity and the material quantity detected in the previous step, and the situation that the material quantity still exists between the second liquid level detection device and a subsequent third liquid level detection device or between the third liquid level detection device and a subsequent fourth liquid level detection device is indicated, and the steps can be repeated to continuously detect the material quantity between the liquid level detection devices. If Δ L2 is Δ L- Δ L1, it means that the amount of the material remaining after the last detection is present between the first liquid level detection device and the second liquid level detection device, and at this time, the water may be continuously filled up to the required volume (i.e., the target water amount). Since Δ L2 is 50mL, and Δ L2 is Δ L (200mL) - Δ L1(150mL), it is checked that the user has added a sufficient amount of the target material, and the water is continuously injected to the target amount.
In the embodiment of the present invention, the liquid levels detected by the first liquid level detecting device, the second liquid level detecting device, and the third liquid level detecting device … … by the nth liquid level detecting device are sequentially increased. And during detection, the amount of the material existing between any two liquid level detection devices can be detected, and the detection is not limited to the detection of the amount of the material existing between two adjacent liquid level detection devices.
It should be noted that, if the water injection reaches the volume M required by the user when reaching the Nx liquid level electrode, it is still impossible to detect whether the material still remains above the liquid level, and an alarm can be given to prompt the user that the material is placed too much.
In the embodiment of the invention, after the food processor calculates the material amount actually added by the user according to the steps in an accumulation way, the accumulated material amount can be compared with the initially calculated target material amount to determine whether the accumulated material amount reaches the target material amount, and when the accumulated material amount just reaches the target material amount, the corresponding food processing function can be started; when the accumulated material amount does not reach the target material amount, the user can be reminded to continue adding the material, and the amount of the material which continues to be added can be given.
Example two
The scheme of the embodiment further optimizes the food processing technology on the basis of the first embodiment.
Optionally, the method may further include:
when water is injected to each liquid level, the materials are stirred at a preset low rotating speed so as to be flatly paved at the bottom of the crushing cavity.
In the embodiment of the invention, the materials are likely to be stacked together when being put in, so that more liquid level detection devices are needed for detection, and the liquid is circulated by stirring of the motor, so that the materials can be uniformly spread at the bottom of the crushing cavity, and the material quantity can be judged more quickly.
Alternatively, the preset low rotation speed may include: 1500rpm to 6000 rpm.
In the embodiment of the present invention, the following embodiment schemes may be adopted in specific implementation: starting a stirring program, keeping the rotating speed between 1500rpm and 6000rpm, stirring the pulp for 3 seconds at intervals of 3 seconds, circulating for 3 times, and stirring the pulp while continuing to inject water.
Particular arrangements
EXAMPLE III
The embodiment is further defined by the processing technology of the food processor on the basis of any embodiment.
Alternatively, the food processing function may comprise a plurality, and the different food processing functions correspond to one or more food processing techniques.
In the embodiment of the invention, different food processing functions can respectively correspond to different food processing technologies, and the same food processing function can also correspond to different food processing technologies. For the same food processing function, when the deviation of the processing capacity is large, different processing technologies can be set for different processing capacities.
In the embodiment of the invention, the common food processor usually has only function selection and no processing capacity selection, and after the food processing function is started, food processing is carried out according to a processing technology no matter how much material is added and the water level is high or low, so that good food processing effect can not be ensured under all conditions. The scheme of the embodiment of the invention can directly identify the requirements of the user on the processing function and the processing capacity, and optimize the food processing technology aiming at different processing functions and different processing capacities in the product development stage so as to ensure that a better food processing effect can be achieved under the conditions of each food processing function and processing capacity.
