In order to make those skilled in the art better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The technical terms related to the present application are:
PPG: programmable Pulse Generator, programmable Pulse Generator.
eeprom: electrically Erasable Programmable Read Only Memory (EEPROM).
Example 1
It should be noted that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in an order different from the order shown or described herein.
Fig. 1 is a schematic flow chart of a method for determining material of an inner pot according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S102, acquiring a voltage value and a first programmable pulse wave value of the inner pot to be tested in the heating process;
step S104, calculating a second programmable pulse wave value when the voltage value and the first programmable pulse wave value operate at a rated voltage;
and S106, comparing the second programmable pulse wave value with a prestored programmable pulse wave value, and determining the material of the inner pot according to the comparison result.
Specifically, the method for determining the material of the inner pot provided by the embodiment of the present application may be applied to a cooking appliance, where the cooking appliance takes an electric pressure cooker as an example, and with reference to steps S102 to S106, the controller of the method for determining the material of the inner pot provided by the embodiment of the present application may obtain different powers by adjusting the PPG values, the PPG values sent by the same inner pot corresponding to the same power under the same voltage are the same, and the PPG values of the inner pots made of different materials are different greatly under the same cooking conditions (the voltage and the power are the same). Usually heating at a rated power of 1600W under a rated voltage (220 v), and the PPG value generated by the heating of the stainless steel pot controlled by the controller is about 100 (between 90 and 110). The PPG value generated by replacing the aluminum inner pot is about 140 (between 120 and 150).
Therefore, if the PPG values of different pots can be obtained in advance, the material of the inner pot currently used for cooking can be obtained by comparing the actual PPG value (i.e., the second programmable pulse wave value in the embodiment of the present application) with the PPG value obtained by using the inner pot of the specified material in advance (i.e., the pre-stored programmable pulse wave value in the embodiment of the present application) in the subsequent cooking.
Wherein, in the PPG acquisition process, the current working voltage can be acquired at the same time, the PPG values corresponding to different voltage ranges are different,
as shown in Table 1: a PPG value corresponding table of voltage under the standards of 0.28mm and 1600W of the inner pot fusion-jetting magnetic conduction layer;
TABLE 1
Figure BDA0001810599520000051
The PPG value is also related to the thickness of the magnetic conductive layer, and under the same working condition, when the magnetic conductive layer is 0.21, the PPG value is increased, as shown in table 2:
TABLE 2
Figure BDA0001810599520000052
Therefore, the inner pot produced by different processes is difficult to judge the material by only depending on PPG value. The PPG value of a specific material is acquired at an early stage for judgment. The user actually uses the inner pot made of which material.
According to the method for judging the material of the inner pot, the PPG value of the inner pot is obtained under the appointed working condition through the appointed material, the PPG value is stored for the subsequent user to actually cook, and the currently used pot can be accurately judged.
Specifically, when a tester is specified to test with a stainless steel pot under a factory test mode, namely, the acquired PPG value is stored as the value of the stainless steel pot, the possibility of judgment errors caused by process differences in the manufacturing process of the inner pot can be eliminated, and accurate judgment can be realized.
In the embodiment of the invention, the mode of the currently used cooker can be accurately judged by obtaining the PPG value of the inner cooker made of the specified material under the specified working condition and storing the PPG value for the subsequent user to actually cook, and the voltage value and the first programmable pulse wave value of the inner cooker to be detected in the heating process are obtained; calculating a second programmable pulse wave value when the second programmable pulse wave value runs at the rated voltage according to the voltage value and the first programmable pulse wave value; the second programmable pulse wave value is compared with the prestored programmable pulse wave value, and the material of the inner pot is determined according to the comparison result, so that the purpose of effectively identifying the material of the inner pot is achieved, the technical effect of accurately controlling according to the material of the inner pot is achieved, and the technical problem that accurate control cannot be performed according to the material of the inner pot in the heating process due to the fact that judgment of the material of the inner pot is lacked in the related technology is solved.
In summary, the method for judging the material of the inner pot provided by the embodiment of the application is as follows:

Step2, heating for T1 time at constant power P1, and acquiring a voltage value and a PPG0 value in the heating process by using a controller;
step3, calculating a PPG value under the rated voltage through the acquired voltage value and the PPG0 value, and storing the PPG value into the EEPROM;
and Step4, stopping working and exiting the test mode.
Fig. 2b is a schematic flow chart of another method for determining material of an inner pot according to an embodiment of the present invention in a factory test mode, as shown in fig. 2b, in a user mode:
step1, selecting a cooking function for cooking;
step2, heating for a time of T1 with a constant power P1, and acquiring a voltage value and a PPG1 value (i.e., a first programmable pulse value in the embodiment of the present application) in the heating process by a controller;
step3, calculating a PPG2 value (i.e., a second programmable pulse wave value in the embodiment of the present application) under the rated voltage through the acquired voltage value and the PPG1 value, and comparing the calculated PPG2 value with the PPG stored in the EEPROM;
step4, determining whether the PPG2 value is within an error range of the PPG value (i.e., the pre-stored programmable pulse wave value in the embodiment of the present application), if so, the inner pot used by the user is an inner pot made of a pre-specified material, otherwise, the inner pot is made of another material.

and step S101, storing the programmable pulse wave value when the pressure cooker operates at the rated voltage so as to achieve the technical effect of accurately controlling according to the material of the inner pot.
