[0031] Base 100, stirring cup 200, stirring assembly 300 and driving assembly 400 DETAILED DESCRIPTION

[0032] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0033] In current kitchen equipment, fixed programs are set for users to choose from. Depending on the program selected by the user, the control system of the kitchen equipment controls the equipment to operate according to the set parameters, which reduces the difficulty of making food. However, the existing technology is set according to multiple required functions and cannot automatically identify the type and weight of ingredients. Different types and weights of ingredients are operated according to fixed parameters. The difference in ingredient weight will affect the taste of the dishes. To solve this problem, the present invention proposes a control method for kitchen equipment, which is applied to kitchen equipment with a stirring component. As shown in Figure 5, the kitchen equipment generally includes a base 100, a stirring cup 200, a stirring component 300 and a driving component 400. The driving component 400 drives the stirring component 300 to rotate to stir and cut the ingredients in the stirring cup 200.

[0034] The control method of the kitchen equipment is shown in Figure 1-4. The control method includes:

[0035] Step S100: obtaining a working current value of a driving component that drives the stirring component to rotate after the food is placed in the kitchen device within N working hours;

[0036] Step S200: comparing the working current value during the Nth working time with the corresponding interval target current value. If the working current values ​​during the Nth working time all match the corresponding interval target current values, the stirring program is automatically matched.

[0037] Step S300: Compare the working current value within the Nth working time with the corresponding interval target current value. If the working current values ​​within the N working times all match the corresponding interval target current values, calculate the current value change magnification of the working current value within the N working times. If the current value change magnification of the working current value matches the corresponding interval target current value change magnification, automatically match the stirring program.

[0038] Said N≥2.

[0039] Specifically, when the kitchen appliance is started, the driving component 400 drives the stirring component to stir the load according to the set constant voltage. In step S100, the working current during operation can be detected by a current detection circuit provided in the kitchen appliance. The current detection circuit can be a commonly used constantan wire resistance current or a current sensor to detect the working current in real time.

[0040] If N=2, then:

[0041] Step S100, obtaining a working current value A1 of a driving component that drives the stirring component to rotate within a first working time T1 after placing food into the kitchen device;

[0042] Step S200, comparing the working current value A1 within the first working time T1 with the corresponding interval target current value B1. If the working current value A1 within the first working time T1 does not match the corresponding interval target current value B1, performing a manual matching stirring procedure; if the working current value A1 within the first working time T1 matches the corresponding interval target current value B1, returning to step S100, obtaining the working current value A2 of the driving component that drives the stirring component to rotate after the food is placed in the kitchen device within the second working time T2;

[0043] Then enter step S200: if the working current value A2 within the second working time T2 does not match the corresponding interval target current value B2, perform a manual matching stirring program; if the working current value A2 within the second working time T2 matches the corresponding interval target current value B2, automatically match the stirring program.

[0044] If N=3, then after matching the working current value A2 within the second working time T2 with the corresponding interval target current value B2, the process returns to step S100 to obtain the working current value A3 of the driving component that drives the stirring component to rotate after the food is placed in the kitchen device within the third working time T3; then the process proceeds to step S200: if the working current value A3 within the third working time T3 does not match the corresponding interval target current value B3, a manual matching stirring program is performed; if the working current value A3 within the third working time T3 matches the corresponding interval target current value B2, a stirring program is automatically matched;

[0045] Thus, the value of N can continue to increase and can be set to 4, 5, 6, etc., and the above steps S100 and S200 are repeated.

[0046] It can be understood that, under the working current values ​​obtained within N working hours, if the N working current values ​​all match the corresponding interval target current values, the stirring program can be automatically matched. If any working current value does not match the interval target current value, the stirring program is manually matched instead.

[0047] Furthermore, in addition to the above-mentioned automatic matching of the stirring program by matching the working current value with the interval target current value, step S300 may be added to improve the accuracy.

[0048] If N=2, on the premise that the working current value A1 in the first working time T1 matches the corresponding interval target current value B1, and the working current value A2 in the second working time T2 matches the corresponding interval target current value B2, calculate the current value change rate C of the working current value in the first working time T1 and the second working time T2, and compare it with the corresponding interval target current value change rate D. If the current value change rate C matches the interval target current value change rate D, the stirring program is automatically matched, otherwise the stirring program is manually matched.

[0049] Furthermore, when the working current value does not match the interval target current value and the stirring program is manually matched, the driving component stops operating;

[0050] Also, when the current value variation ratio C does not match the interval target current value variation ratio D, and the stirring program is manually matched, the driving component stops running.

[0051] Furthermore, the first working time T1, the second working time T2, and the Nth working time TN specifically refer to time within a certain range, wherein the first working time T1 is set to refer to the time 0-4S after the drive component is started; and the specific time period range of the second working time T2 and the Nth working time TN is set according to the model parameters of the actual drive component.

[0052] Furthermore, the step S100 of obtaining the working current value of the driving component that drives the stirring component to rotate during the first working time after the food is placed in the kitchen device includes:

[0053] S101 , obtaining multiple current values ​​of a driving component within a first working time T1 , comparing the multiple current values, and taking a peak current as a working current value A1 within the first working time T1 .

[0054] As described above, the working current during operation is detected by the current detection circuit provided in the kitchen equipment. The current detection sampling time △t is set. After the kitchen equipment is started, the current is sampled once at an interval of △t to measure the current value. After measuring multiple current values, the maximum current value is obtained by comparison. This maximum current value is defined as the peak current, and the peak current is used as the working current value A1 within the first working time T1.

[0055] Furthermore, the step 200 further includes:

[0056] Step S201: if the working current value A1 within the first working time T1 matches the corresponding interval target current value B1, the type of food is determined;

[0057] Specifically, the target current values ​​B1 of different types of food in the first working time T1 are pre-recorded, and the type of food is determined based on the interval target current value B1 matched to the working current value A1 in the first working time T1;

[0058] If the food types are divided into a first category of high hardness food, a second category of medium hardness food, and a third category of low hardness food according to hardness, then when the driving component is driven, within the first working time T1, the interval target current values ​​B1 obtained by stirring the three different types of food are different, as shown in the following query table 1:

[0059] The above-mentioned query table 1 is stored in the memory of the kitchen equipment. Then, the operating current value A1 obtained during the first operating time T1 is compared with the interval target current value B1 in the query table 1 to determine the type of food. If the operating current value A1 equals the interval target current value B12, the food is determined to be the second category.

[0060] In this embodiment, the driving component is a motor. When the motor drives the stirring component to rotate initially, due to the different hardness of the food, it will generate peak currents with different no-load current ratios. Subsequently, with high-speed stirring, the current value will tend to stabilize according to different load conditions. Therefore, within the first working time T1 when the kitchen equipment is started, the type of food can be judged based on the measured working current value A1 (i.e., peak current).

[0061] Depending on the actual settings, the types of ingredients can be further subdivided into four categories or even more.

[0062] Furthermore, the step S100 of obtaining the working current value of the driving component that drives the stirring component to rotate after the food is placed in the kitchen device during N working hours also includes:

[0063] Step S102: when obtaining the operating current value within the Nth operating time, if N≠1, obtaining multiple current values ​​of the driving component within the Nth operating time, and calculating the average current value of the multiple current values ​​as the operating current value within the Nth operating time;

[0064] Specifically, when N=2, the working current is detected by the current detection circuit provided in the kitchen appliance during the second working time T2. A sampling time Δt is set for the current detection. After the kitchen appliance is started, a sampling circuit is performed once every Δt period to measure the current value. After measuring the current values ​​multiple times, the average of the multiple current values ​​is calculated as the working current value A2 during the second working time T2.

[0065] Alternatively, after measuring multiple current values, the maximum current value and the minimum current value are removed, and the average value of the multiple current values ​​is calculated as the working current value A2 in the second working time T2.

[0066] Furthermore, the step 200 further includes:

[0067] Step S202: comparing the working current value within the Nth working time with the corresponding interval target current value, if the working current value within the Nth working time matches the corresponding interval target current value, determining the amount of food, where N≠1.

[0068] Specifically, if N=2, the interval target current values ​​B2 of different types of ingredients and different weights of ingredients within the second working time T2 are pre-recorded, and the amount of ingredients is determined based on the interval target current value B2 matched to the working current value A2 within the second working time T2.

[0069] If the weight of the ingredients is divided into light load and heavy load according to a gradient distribution, then when the driving component is driven, within the first working time T1, according to the matching of the working current value A1 with the target current value B1, continuing the above, it has been concluded that the type of ingredients is the second type of ingredients, and the interval target current value B2 obtained by stirring the second type of ingredients of different weights is different, as shown in the following query table 2:

[0070] The above-mentioned query table 2 is stored in the memory of the kitchen equipment. Then, the operating current value A2 obtained during the second operating time T2 is compared with the interval target current value B2 in the query table 2 to determine the weight of the second type of food. If the operating current value A2 equals the target current value B221, the weight is determined to be a light load.

[0071] Of course, the query table 2 also stores a corresponding query table of the current value and weight of the first type of food, and a corresponding query table of the current value and weight of the third type of food.

[0072] According to the actual settings, the food weight gradient can be changed, such as dividing the full load weight into three, four, five, etc. If the full load weight is divided into three, it is divided into 1 / 3 load, 2 / 3 load and full load.

[0073] Based on the above, defining N=2, the following query table 3 is obtained:

[0074] In the above-mentioned automatic matching stirring program, the stirring program at least includes the motor speed and the motor rotation time. After the automatic matching stirring program, the driving component runs according to the matched speed and rotation time, and stops after running to the set rotation time, thereby achieving the purpose of automatic stirring and making the food taste better.

[0075] In this embodiment, the kitchen appliance may be a juicer, which is mainly capable of crushing ice and making juice. Therefore, the program can be simplified to automatically identify the types of ingredients as first-category ice cubes and second-category juice, and automatically identify the weights of the first-category ice cubes and second-category juice.

[0076] After placing the ingredients into the blender cup, the driving component starts and obtains the working current value A1 within the first working time T1. The working current value A1 is compared with the interval target current value B1. If the working current value A1 matches the interval target current value B11 for the first category of ingredients, it is determined to be ice cubes of the first category; if the working current value A1 matches the interval target current value B12 for the first category of ingredients, it is determined to be juice of the second category;

[0077] The working current value A2 is obtained during the second working time T2. Based on the first judgment that it is the first category of ice cubes, the working current value A2 is compared with the target current value B2 of the first category of ingredients. If the working current value A2 is adapted to the target current value B211 of the first category of ingredients, it is judged to be a light load; if the working current value A2 is adapted to the target current value B212 of the first category of ingredients, it is judged to be a heavy load.

[0078] The working current value A2 is obtained during the second working time T2. Based on the first judgment that it is the second category of food juice, the working current value A2 is compared with the target current value B2 of the first category of food interval. If the working current value A2 is adapted to the target current value B221 of the second category of food juice interval, it is judged to be a light load; if the working current value A2 is adapted to the target current value B222 of the second category of food interval, it is judged to be a heavy load.

[0079] According to the type and weight of ingredients determined by the system, the system automatically matches the stirring program, that is, automatically determines the motor speed and running time.

[0080] Furthermore, if the ingredients are matched, it will be converted to a manual matching program. There are also multiple programs to choose from in the manual matching program, such as powdering, grinding, mincing meat, etc.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
