Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A cooking control method of an electric cooker, a cooking control device of an electric cooker, and an electric cooker having the cooking control device according to embodiments of the present invention will be described below with reference to the accompanying drawings.
In the embodiment of the invention, the electric cooker can be a cooking product such as an electric cooker, an electric pressure cooker and the like.
Fig. 1 is a flowchart of a cooking control method of an electric cooker according to an embodiment of the present invention. As shown in fig. 1, the cooking control method of the electric cooker includes the steps of:
s1, after the electric cooker cooks, the current rice water amount of the cooked food of the electric cooker is obtained, and the steam foam generated during cooking of the electric cooker is detected by the foam detection device to judge whether the electric cooker enters a boiling stage or not.
As shown in fig. 2a, an electric cooker such as an electric rice cooker generally includes a preheating and water-absorbing stage, a heating stage, a boiling stage and a stewing stage when cooking rice, and the overflow phenomenon of the electric cooker generally occurs in the boiling stage.
Therefore, whether the electric cooker is in the boiling stage or not can be judged by detecting the steam bubbles through the bubble detecting means, wherein a process of detecting the steam bubbles through the bubble detecting means to judge whether the electric cooker is in the boiling stage or not will be described in detail in the following embodiments.
And S2, if the electric cooker enters the boiling stage, controlling the electric cooker to heat at a first power adjusting ratio, and calculating the delayed charging time according to the amount of rice water of the food cooked by the electric cooker.
According to an embodiment of the present invention, in step S2, after the electric cooker enters the boiling stage, the electric cooker may be further controlled to stop heating for a first preset time before the electric cooker is controlled to heat at the first power adjustment ratio. That is, after the electric cooker enters the boiling stage, the electric cooker can be controlled to stop heating for a period of time and then be controlled to heat at the first power regulation ratio.
And S3, when the time for heating the electric cooker in the first power regulation ratio reaches the delayed feeding time, controlling the electric cooker to send feeding prompt information, and after feeding, controlling the electric cooker to heat in the second power regulation ratio until the boiling stage is finished, wherein the second power regulation ratio is larger than or equal to the first power regulation ratio.
When the time for heating by the first power adjusting ratio reaches the delayed charging time, the electric cooker can be used for sounding or reminding a user of charging in other modes, or the electric cooker can be used for automatically charging.
It can be understood that, in the embodiment of the present invention, when the foam detection device detects the steam foam, it is determined that the electric cooker has entered the boiling stage, so that the boiling stage is realized by triggering the foam detection device after the electric cooker enters the boiling stage, and is not affected by the boiling point of water. After the electric cooker enters the boiling stage, the electric cooker can be controlled to heat by adopting a smaller power regulation ratio, such as a first power regulation ratio, and then the delayed feeding time is calculated according to the obtained rice water amount of the food cooked by the electric cooker at present, so that the accuracy of the delayed feeding time can be ensured, the influence of the water boiling point is avoided, and the accuracy is related to the rice water amount of the food cooked by the electric cooker at present. And finally, when the time for heating the electric cooker by the first power regulation ratio reaches the delayed feeding time, controlling the electric cooker to send feeding prompt information to ensure that feeding is carried out at the optimal time, and controlling the electric cooker to heat by a larger power regulation ratio, such as a second power regulation ratio, after feeding until the boiling stage is finished. The second power modulation ratio may be greater than or equal to the first power modulation ratio.
It should be noted that the first power adjustment ratio refers to the power adjustment ratio that is adopted first when the electric cooker enters the boiling stage, and generally, the power adjustment ratio is smaller than the equivalent power of the power adjustment ratio that is adopted after the electric cooker is added. Of course, in other embodiments of the present invention, the heating power of the electric cooking device may be described instead of the power adjustment ratio, and in fact, the heating power of the electric cooking device may be obtained by equivalent calculation of the power adjustment ratio.
That is, in an embodiment of the present invention, the power for controlling the electric cooker to perform the heating operation may be calculated according to the power adjustment ratio of the electric cooker.
Wherein, the power regulation ratio of the electric cooker is the ratio of the heating time of the electric cooker in one power regulation period to the time of the power regulation period.
In the embodiment of the invention, after the steam foam is detected by the foam detection device to judge that the electric cooker enters the boiling stage, the electric cooker can be controlled to heat by a first power regulation ratio, the first power regulation ratio refers to the ratio of the heating time in one power regulation period to be actually adopted after the electric cooker enters the boiling stage to the time of the power regulation period, and the heating time corresponding to the first power regulation ratio is usually counted in seconds. That is, before the material is added in the boiling stage, the electric cooker performs intermittent heating according to the first power regulation ratio, namely, the electric cooker performs heating for a period of time t1 in one power regulation period, stops heating for another period of time t2, the sum of t1 and t2 is the time of one power regulation period, and t1 is the heating time corresponding to the first power regulation ratio.
In the embodiment of the present invention, the time of one power modulation period may be equal regardless of the first power modulation ratio or the second power modulation ratio.
According to one embodiment of the invention, the step of obtaining the rice water amount of the food cooked by the electric cooker comprises the following steps: detecting the temperature of the bottom of an inner pot of the electric cooker, and starting timing through a first timer when the temperature of the bottom of the inner pot reaches a first preset temperature; detecting the temperature of an upper cover of the electric cooker, and controlling the first timer to stop timing when the temperature of the upper cover reaches a second preset temperature, wherein the second preset temperature is higher than the first preset temperature; and calculating the amount of rice water of the food cooked by the electric cooker according to the timing time of the first timer.
Specifically, as shown in fig. 2c, when an electric cooking device such as an electric rice cooker cooks rice in a hot pot, the first temperature sensor detects the temperature of the bottom of the pot, when the temperature value detected by the first temperature sensor reaches a first preset temperature TEMP1, the first timer starts timing, then the second temperature sensor detects the temperature in the upper cover of the electric rice cooker, when the temperature value detected by the second temperature sensor reaches a second preset temperature TEMP2, the first timer stops timing, at this time, the timing time of the first timer is T1, and finally the rice water amount N is calculated according to a functional formula N ═ F2(T1), where N is a positive integer.
In the cooking process of the electric cooker, for example, an electric rice cooker to cook hot pot rice, as shown in fig. 2b, after the electric rice cooker enters a boiling stage, the electric rice cooker is controlled to heat with a first power P1 (obtained by equivalent calculation of a first power regulation ratio), then the rice water amount N is calculated according to a functional formula N-F2 (T1), and then the delayed charging time T2 is calculated according to the rice water amount N and a functional formula T2-F1 (N). When the time that the electric cooker heats with P1 reaches the time delay feeding time T2, the electric cooker is controlled to send feeding prompt information to prompt that the food is added or the food is automatically added, after the food is added, the electric cooker is controlled to heat with a second power P2 (obtained by equivalent calculation of a second power regulation ratio), then the time T3 that the electric cooker heats with the second power P2 is calculated according to the temperature of the bottom of the cooker, and when the time T3 reaches, the boiling stage is finished.
Therefore, in the embodiment of the invention, during the process of cooking the rice in the pot, the electric cooker such as the electric rice cooker triggers the foam detection device after the rice is boiled, so that the boiling detection is realized and the influence of the boiling point of water is avoided. After boiling is detected, the time delay dish adding time is calculated according to the rice water amount obtained by the cooking curve of the rice cooker, such as the curve shown in fig. 2a, and after the time delay dish adding time is reached, a buzzer buzzes or other modes remind a user to add dishes or automatically add dishes, so that the function of the pot rice is realized.
Specifically, as shown in fig. 3a to 7b, the foam detecting device 10 is disposed in the upper cover of the electric cooker, and the foam detecting device 10 includes at least one foam sensing element 101, wherein when each foam sensing element 101 senses steam foam generated by the electric cooker, a capacitance value of the foam detecting device 10 changes; the detection module comprises a capacitance detection chip 20, the capacitance detection chip 20 is connected with the foam detection device 10, the capacitance detection chip 20 generates a foam detection signal through detecting the capacitance value change condition of the foam detection device 10, the capacitance detection chip 20 is connected with the main control module 40, the main control module 40 is connected with the heating power control module 30, the heating power control module 30 is used for controlling the heating power of the electric cooking device, and when the main control module 40 judges that the capacitance value of the foam detection device 10 changes according to the foam detection signal, the electric cooking device is judged to enter a boiling stage.
Specifically, in the process that the electric cooker heats rice water in the inner pot, the capacitance detection chip 20 can detect the capacitance value variation of the foam detection device 10 in real time, when the electric cooker is in a water absorption stage and a heating stage, the temperature of a rice water mixture in the inner pot of the electric cooker is low, no steam foam or only a small amount of steam foam is generated, and the capacitance value of the foam detection device 10 is not changed; after rice water in the inner pot is heated to boiling, steam foam generated by boiling can contact the foam sensing assemblies 101 arranged at different positions, the capacitance value of each foam sensing assembly 101 can be changed when the foam sensing assembly is contacted with the steam foam, and then the capacitance value of the foam detection device 10 is changed. Further, the capacitance detection chip 20 detects a capacitance variation of the foam detection device, and if the capacitance variation of the foam detection device 10 is smaller than or equal to a preset threshold, the main control module 40 determines that the capacitance of the foam detection device 10 is not changed, and controls the electric cooker to keep the current heating state; if the capacitance value variation of the foam detection device 10 is larger than the preset threshold, the capacitance value of the foam detection device is judged to be changed, and the electric cooker is detected to enter a boiling stage.
According to one embodiment of the present invention, as shown in fig. 3a and 4, each of the foam sensing assemblies 101 is disposed in the steam channel 3 of the upper cover 4 or on the lower surface of the upper cover. As shown in fig. 3a, the foam induction assembly 101 may be one, and the foam induction assembly 101 is disposed in the steam passage 3 of the electric cooker, and the steam flowing direction in the steam passage 3 is as shown by the arrow in fig. 3 a.
Specifically, when the rice water in the inner pot of the electric cooker is heated and boiled, the steam bubbles generated in the inner pot of the electric cooker contact the bubble sensing assembly 101 according to the flowing direction shown in fig. 3a, and the capacitance detecting chip 20 detects the capacitance variation of the foam detecting device 10 to generate the foam detecting signal. Furthermore, the main control module 40 determines whether the capacitance value of the foam detection device 10 changes according to the foam detection signal, and when the capacitance value variation of the foam detection device 10 is greater than the preset threshold, the main control module 40 determines that the capacitance value of the foam detection device 10 changes, thereby determining that the electric cooking device enters the boiling stage.
According to an embodiment of the present invention, as shown in fig. 3b, the power terminals of the capacitance detection chip 20 and the main control module 40 are connected to a preset power supply VDD, the preset power supply VDD is used for supplying power to the capacitance detection chip 20 and the main control module 40, and a first resistor R1 is further connected between the capacitance detection chip 20 and the foam detection device 10. Wherein, first resistance R1 is used for carrying out filtering processing to the capacitance value variation signal of foam response subassembly 101 to can play anti-jamming effect.
According to a specific example of the present invention, the resistance value of the first resistor R1 may be 10 Ω to 10k Ω.
According to an embodiment of the present invention, when the number of the bubble sensing members 101 is plural, the height between the installation position of each bubble sensing member 101 and the horizontal plane becomes gradually higher. In other words, the distance between each foam sensing assembly 101 and the surface of the rice-water mixture is gradually increased. And the higher the setting height of the foam sensing assembly 101 is, the closer the foam sensing assembly 101 is to the steam outlet a in the steam channel.
Specifically, the foam sensing assembly 101 may be disposed at different heights by providing protrusions at different heights in the steam channel 3.
For example, as shown in fig. 4, two foam sensing members 101, i.e., a first foam sensing member 101A and a second foam sensing member 101B, may be disposed in the steam channel 3 of the electric cooker, wherein the second foam sensing member 101B is disposed at the rear end of the steam channel 3, the second foam sensing member 101B is disposed on the upper surface inside the steam channel 3, the first foam sensing member 101A is disposed at the front end of the steam channel 3, and the first foam sensing member 101A is disposed on the protruding portion 301 of the upper surface, and thus, the disposition height of the second foam sensing member 101B is higher than that of the first foam sensing member 101A.
It should be understood that the flowing direction of the steam in the steam channel 3 is as shown by the arrow in fig. 4, and as can be seen from the changing direction of the arrow, the steam bubbles will enter the steam channel after being generated, and gradually approach to the steam outlet a of the steam channel 3 and gradually approach to a higher position, so that the steam bubbles first contact the first foam sensing element 101A and then contact the second foam sensing element 101B.
Specifically, as shown in fig. 4, in the heating process of rice water in the pot of the electric cooker, steam foam may rise to the position of the foam detecting device 10, when the steam foam contacts the first foam sensing element 101A, the capacitance value of the first foam sensing element 101A changes, the capacitance detecting chip 20 detects that the capacitance value variation of the foam detecting device 10 is Δ C1, and Δ C1 is less than or equal to a preset threshold, the capacitance detecting chip 20 may generate a first foam detecting signal, where the first foam detecting signal is a chip readable signal such as a digital signal, and at this time, the main control module 40 determines that the capacitance value of the foam detecting device 10 does not change, so that the main control module 40 controls the heating module 5 to keep the current power adjustment ratio unchanged through the heating power control module 30; continuing to heat, when steam foam contacts the second foam sensing assembly 101B, capacitance values of the first foam sensing assembly 101A and the second foam sensing assembly 101B both change, the capacitance detection chip 20 detects that the capacitance value variation of the foam detection device 10 is Δ C2, and Δ C2 is greater than a preset threshold, the capacitance detection chip 20 can generate a second foam detection signal, wherein the second foam detection signal is a chip readable signal such as a digital signal, and at this time, the main control module 40 determines that the capacitance value of the foam detection device 10 changes, thereby detecting that the electric cooker enters a boiling stage.
It should be noted that the capacitance detecting chip 20 detects the capacitance variation of the foam detecting apparatus 10 as the sum of the capacitance variations of the plurality of foam sensing elements 101.
According to one embodiment of the present invention, the plurality of foam sensing elements 101 are connected together and then connected to the capacitance detecting chip 20.
According to an embodiment of the present invention, as shown in fig. 5a, a plurality of foam sensing elements 101 are connected together and then connected to the capacitance detecting chip 20 through a first resistor R1. Wherein, first resistance R1 is used for carrying out filtering processing to the capacitance value variation signal of foam response subassembly 101 to can play anti-jamming effect.
According to a specific example of the present invention, the resistance value of the first resistor R1 may be 10 Ω to 10k Ω.
According to one embodiment of the present invention, each of the foam sensing members 101 is connected to the capacitance detecting chip 20.
According to an embodiment of the present invention, as shown in fig. 5b, each of the foam sensing elements 101 is connected to the capacitance detecting chip 20 through a second resistor R2. Wherein, second resistance R2 is used for carrying out filtering processing to the capacitance value variation signal of foam response subassembly 101 to can play anti-jamming effect.
According to a specific example of the present invention, the resistance value of the second resistor R2 may be 10 Ω to 10k Ω.
According to an embodiment of the present invention, as shown in fig. 6, each foam sensing assembly 101 includes a foam contact portion 11 and a sensing portion 12, wherein the foam contact portion 11 is an insulator 100, the sensing portion 12 is a conductor 200, and the insulator 100 isolates the vapor foam from the conductor 200.
Specifically, as shown in fig. 6, the insulator 100 defines a receiving cavity 120 with an open upper surface, and the conductive body 200 defines an upper surface, a lower surface and side surfaces, wherein the conductive body 200 is disposed in the receiving cavity 120, the insulator 100 covers the lower surface and the side surfaces of the conductive body 200 at the same time, and the upper surface of the conductive body 200 is exposed from the insulator 100 so as to be connected to the capacitance detecting chip 20. Thus, by combining insulator 100 and conductor 200, capacitive foam sensing assembly 101 can be formed.
When the foam contact part 11 of the foam sensing assembly 101 is not contacted with the steam foam, each foam sensing assembly 101 in the foam detection device 10 only has the parasitic capacitance of the foam sensing assembly itself; when rice water in a pot in the electric cooker is heated and boiled, the generated steam foam and the foam contact part 11 and the sensing part 12 of the foam sensing component 101 form a capacitor, and according to the determining formula of the capacitor:
(wherein, S is the opposite surface area, d is the distance between the polar plates) shows that the more intensely the rice water in the pot of the electric cooker is heated and boiled, the more steam foams are generated,the larger the area of the bubble contact portion 11 covered by the vapor bubbles is, the larger the facing surface area S between the electrode plates is, and the larger the amount of change in capacitance value of the bubble detection device 10 is.
Therefore, the foam detection device isolates the steam foam from the conductive body 200 through the insulator 100, the insulator 100 is indirectly contacted with the steam foam, and the steam foam is detected by detecting the capacitance value change of the foam induction component 101, so that the non-electric contact detection of the foam is realized.
According to an embodiment of the present invention, the insulator 100 is disposed adjacent to the conductor 200. Wherein the insulator 100 may have a thickness of 1-10 mm.
Specifically, the equation for the capacitance-based decision is:
it is understood that the larger the thickness of the insulator 100, the larger the inter-plate distance d, and the smaller the amount of change in capacitance in the case where the amount of steam bubbles overflowing is the same. In this way, the thickness of the insulator 100 can be selected as the case may be.
A foam sensing assembly 101 for an electric cooker according to one embodiment of the present invention will be described with reference to fig. 7 a.
As shown in fig. 7a, a foam sensing assembly 101 for an electric cooker according to an embodiment of the present invention includes an insulator 100 and an electric conductor 200.
Specifically, the conductive body 200 is horizontally disposed, that is, the thickness direction of the conductive body 200 is oriented in the up-down direction, whereby the lower surface of the conductive body 200 faces horizontally downward and the lower surface of the insulator 100 (i.e., the detection surface 110) faces horizontally downward, increasing the effective detection area, thereby improving the sensitivity of the overflow detection.
Alternatively, the area of the detecting surface 110 may be determined according to the size requirement of the detecting signal in practical application. For example, the area of the detection surface 110 is 50mm2-400mm2On the one hand, when there is less foam to touch the detection surface 110, it can still be guaranteed that the change in capacitance is large enough to facilitate detection, and on the other hand, it can be guaranteed that the interference of the outside to the overflow detection is small.
Advantageously, the detecting surface 110 is circular, i.e. the conductive body 200 is a circular piece, which not only facilitates the manufacturing process, but also the cross section of the cooking cavity of the electric cooking device is generally circular, and the circular detecting surface 110 has higher applicability.
Of course, the conductive body 200 and the detecting surface 110 may have any other shapes, and the present invention is not limited thereto.

Thereby, the reliability of the overflow detection function of the foam sensing assembly 101 may be improved.
Specifically, as shown in fig. 7a, the insulator 100 defines a receiving cavity 120 with an open upper surface, the conductive body 200 is disposed in the receiving cavity 120, the insulator 100 covers the lower surface and the side surface of the conductive body 200 at the same time, and the upper surface of the conductive body 200 is exposed from the insulator 100 so as to be connected to the capacitance detecting chip.
Advantageously, as shown in fig. 7a, the height of the accommodating cavity 120 is greater than the thickness of the conductive body 200, and the conductive body 200 is disposed at the bottom of the accommodating cavity 120, so that the conductive body 200 can be stably placed in the insulator 100 due to the smaller thickness of the conductive body 200, and the conductive body 200 is prevented from falling out of the accommodating cavity 120 of the insulator 100.
