The first heating system is electromagnetic induction heating, and the second heating system is conduction / radiation heating implemented by an electromagnetic heating film (placed under the ceramic glass panel, which can generate eddy currents in a changing magnetic field, thus increasing the temperature).

[0051] As Figure 1 shown, the double heater has two heating systems. The first heating system is electromagnetic induction heating, and the second heating system is electromagnetic heating film to achieve conduction / radiation heating (placed under the microcrystalline panel, and can generate eddy currents in a changing magnetic field, thereby increasing the temperature). A film (the material can be metal, graphite, etc.) is closely attached above / below the microcrystalline panel. When the wire coil generates a changing magnetic field, the changing magnetic field first generates eddy currents on the film, and the film will heat up, and the heat is transferred to the pot through the way of conduction / radiation.

[0052] There are many materials for the cookware applied to the above double-heating appliance. The characteristics of different materials of cookware vary greatly when working on the double-heating appliance. In order to make the double-heating appliance work in the best state, it is necessary to determine the material of the used cookware.

[0053] In view of this, the present application proposes a cookware type detection method, device and household appliance, which obtain the maximum output power of the heating wire coil of the double-heating appliance and the maximum bearing power of the heating film; the double-heating appliance heats the cookware according to the detected power and detects the target parameters of the heating wire coil; according to the target parameters of the heating wire coil, the maximum output power and the maximum bearing power of the heating film, the cookware type is judged. Compared with the prior art, the double-heating appliance adopting this solution can detect the cookware type during operation, and then adjust relevant heating parameters according to the cookware type to ensure the reliability of the heating film and the circuit board of the double-heating appliance.

[0054] To make the above objects, features and advantages of the present application more obvious and understandable, the following detailed description of the specific embodiments of the present application will be given with reference to the accompanying drawings.

[0055] Embodiment 1

[0056] Figure 2 is a flowchart of a cookware type detection method provided by an embodiment of the present application. This method is applied to a double-heating appliance. As Figure 1 shown, this cookware type detection method includes:

[0057] Step S101: Obtain the maximum output power of the heating wire coil and the maximum bearing power of the heating film;

[0058] Step S102: Heat the cookware according to the detected power and detect the target parameters of the heating wire coil;

[0059] Step S103: Judge the cookware type according to the target parameters of the heating wire coil, the maximum output power and the maximum bearing power of the heating film.

[0060] In this embodiment, the double-heating appliance shown in Figure 1 is taken as an example for introduction.

[0061] In step S101, under different voltage conditions, the maximum output power P of the heating wire coil max is different. For example, if the double-heating appliance is currently connected to the mains power supply, the voltage of the mains power supply in different places is often different. Since the relevant parameters such as the impedance of the heating wire coil are known, in this embodiment, the current input voltage of the double-heating appliance can be detected, and the maximum output power P of the heating wire coil can be calculated according to the current input voltage and the relevant parameters of the heating wire coil max . The maximum bearing power P0 of the heating film can be calculated according to the relevant parameters such as the thickness and material of the heating film.

[0062] In step S102, the detection power is the heating power of the heating wire coil set when adopting the cooking utensil type detection method. Different detection powers correspond to different target parameters. The target parameter can be the actual output power P of the heating wire coil or the actual turn-on frequency f of the switching tube of the heating wire coil. The switching tube is, for example, an IGBT (Insulated Gate Bipolar Transistor).

[0063] In step S103, according to the target parameter, the maximum output power of the heating wire coil, and the maximum load-bearing power of the heating film, the cooking utensil type is determined.

[0064] Specifically, the present embodiment provides the following two implementation manners.

[0065] In the first implementation manner, the detection power is set to the maximum output power P max , and the target parameter correspondingly is the actual output power P. Then the above step S102 is specifically: The double heating appliance heats the cooking utensil at the maximum output power P max , and the actual output power P of the heating wire coil is detected. Specifically, it can be implemented as: detecting the actual current of the heating wire coil, and calculating the actual output power of the heating wire coil according to the relevant parameters of the heating wire coil and the actual current.

[0066] Correspondingly, step S103 specifically includes:

[0067] Comparing the actual output power P with the maximum output power P max and the maximum load-bearing power P0. The maximum output power P max is greater than the maximum load-bearing power P0;

[0068] As Figure 3 shown:

[0069] If the actual output power P is equal to the maximum output power P max , then the cooking utensil type is the first type, that is, the current cooking utensil is a metal cooking utensil with a good electromagnetic heating match;

[0070] If the actual output power P is greater than the maximum load-bearing power P0 and less than the maximum output power P max , then the cooking utensil type is the second type, that is, the current cooking utensil is a metal cooking utensil with a poor electromagnetic heating match;

[0071] If the actual output power P is equal to the maximum load-bearing power P0, then the cooking utensil type is the third type, that is, the current cooking utensil is a non-metal cooking utensil or there is no cooking utensil;

[0072] If the actual output power P is less than the maximum load-bearing power P0, a prompt that the heating film has been damaged is sent out.

[0073] The principle of the first implementation mode above is as follows: Since the AC impedance of the electromagnetic heating film is small, when the heating coil outputs the maximum power (such as 2000W), the heating film cannot completely consume the power (such as the maximum can only reach 1000W). Based on this, it is judged whether there is a metal pot. If there is no metal pot, a relatively low maximum heating power is set to ensure that the temperature of the heating film will not be too high and improve the reliability of the heating film. The function of distinguishing between a metal pot with a better match and a metal pot with a worse match is to prevent the circuit board from working in an environment with relatively poor resonance conditions to protect the reliability of the circuit board.

[0074] In the second implementation mode, the detection power is set to the first power P1, and the target parameter corresponds to the actual turn-on frequency f of the switching tube. Among them, the first power P1 is less than the maximum load power P0 of the heating film. Then, the above step S102 is specifically: The dual heating appliance heats the cookware at the first power P1, and detects the actual turn-on frequency f of the switching tube of the heating coil.

[0075] Correspondingly, step S103 specifically includes:

[0076] According to the maximum output power P max and the maximum load power P0, determine the first frequency f1, second frequency f2, third frequency f3, and fourth frequency f4 from small to large as the preset frequency thresholds.

[0077] In practical applications, through a calibration method, according to the maximum output power P max and the maximum load power P0, determine the first frequency f1, second frequency f2, third frequency f3, and fourth frequency f4. For example, 19kHz < f1 < f2 < f3 < f4 < 32kHz.

[0078] Compare the actual turn-on frequency f with the first frequency f1, second frequency f2, third frequency f3, and fourth frequency f4.

[0079] As Figure 4 shown:

[0080] If the actual turn-on frequency f is greater than or equal to the third frequency f3 and less than or equal to the fourth frequency f4, the cookware type is the first type, that is, the current pot is a metal pot with a better electromagnetic heating match;

[0081] If the actual turn-on frequency f is greater than the second frequency f2 and less than the third frequency f3, the cookware type is the second type, that is, the current pot is a metal pot with a worse electromagnetic heating match;

[0082] If the actual turn-on frequency f is greater than or equal to the first frequency f1 and less than or equal to the second frequency f2, the cookware type is the third type, that is, the current pot is a non-metal pot or there is no pot;

[0083] If the actual turned-on frequency f is less than the first frequency f1, a prompt indicating that the heating film is damaged is issued.

[0084] The principle of the second implementation manner above is as follows: Since the AC impedance of the electromagnetic heating film is small, when a fixed power is output (such as 1000 W), the heating film itself can also consume 1000 W of power. However, due to the relatively large inductance of the film coupling, the actual frequency f of the switching tube is relatively low; under the condition of having a metal pot, the inductance coupled between the heating film and the pot is relatively small, so the actual frequency f of the switching tube is relatively high.

[0085] In some embodiments of the present application, if it is determined that the actual output power P of the heating wire coil or the actual turned-on frequency f of the switching tube undergoes a sudden change (not caused by the user operation panel) and exceeds the normal range, the above target parameters are re-detected and then the step of judging the type of cookware is performed to avoid misjudgment.

[0086] In some embodiments of the present application, the above cookware type detection method may further include:

[0087] According to the determined type of cookware, relevant heating parameters are adjusted to enable the dual heating appliance to adjust the heating state.

[0088] Specifically,

[0089] (1) If the current pot is a metal pot with good electromagnetic heating matching, the maximum heating power of the heating wire coil is set to P max ;

[0090] (2) If the current pot is a metal pot with poor electromagnetic heating matching, the maximum heating power of the heating wire coil is set to P m1 , and the maximum power does not exceed P during the entire heating process m1 ;

[0091] (3) If the current pot is a non-metal pot or there is no pot, the maximum heating power of the heating wire coil is set to P m2 , and the maximum power does not exceed P during the entire heating process m2 ;

[0092] (4) If the current heating film is damaged, an error can be reported through various means such as display, buzzer, voice, LED, etc., that is, a prompt indicating that the heating film is damaged is issued.

[0093] In this embodiment, setting different maximum heating powers for different cookwares and reporting an error if the heating film is damaged can ensure the reliability of the heating film and the circuit board of the dual heating appliance compared with the prior art.

[0094] The cookware type detection method of this embodiment obtains the maximum output power of the heating wire coil of the dual heating appliance and the maximum load-bearing power of the heating film; the dual heating appliance heats the cookware according to the detection power and detects the target parameters of the heating wire coil; according to the target parameters of the heating wire coil, the maximum output power and the maximum load-bearing power of the heating film, the cookware type is judged. Compared with the prior art, the dual heating appliance adopting this solution can detect the cookware type during operation, adjust relevant heating parameters according to the cookware type, and ensure the reliability of the heating film and the circuit board of the dual heating appliance.

Such a program for implementing the present application can be stored on a computer-readable medium, or can be in the form of one or more signals. Such signals can be downloaded from an Internet website, or provided on a carrier signal, or provided in any other form.

[0143] It should be noted that the above embodiments are illustrative of the present application rather than restrictive thereof, and those skilled in the art can design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word "comprising" does not exclude the presence of elements or steps not listed in the claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. The present application can be implemented by means of hardware including several different elements and by means of a suitably programmed computer. In a unit claim listing several devices, several of these devices may be embodied by the same item of hardware. The use of the words first, second, and third, etc. does not denote any order. These words may be interpreted as names.

[0144] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
