Technical Field

[0001] This invention relates to the field of cooking appliance technology, and in particular to a control method for a cooking appliance and a cooking appliance. Background Technology

[0002] Existing cooking appliances that combine electromagnetic and infrared heating have two heating modes within the same heating zone. There are two main approaches: one is to use electromagnetic and infrared heating in inner and outer rings for mixed heating; this is simple in structure but has poor heating performance. The other is to use infrared and electromagnetic heating in an overlapping manner for mixed heating. Since both the infrared component and the electromagnetic coil component can be set to a heating area that is comparable to the size of the heating zone, single electromagnetic or single infrared heating can achieve high-power heating, or they can be combined to form high-power heating, resulting in better heating performance.

[0003] However, while existing hybrid heating cooking appliances can achieve hybrid heating, the hybrid heating method is singular, there are many limitations in the use environment, the user experience is poor, and they cannot achieve long-term hybrid heating. Summary of the Invention

This electromagnetic field can pass upwards through the electric heating device to couple with the pot in the heating area, providing electromagnetic heating to the heating area. To achieve cooperation between the electric heating device and the electromagnetic heating device, when the cooking appliance is in the on state, a working command is issued to the cooking appliance. Multiple working commands are used to determine different working modes, enabling the cooking appliance to have multiple different heating methods. After receiving the working command, the cooking appliance can determine the working mode, i.e., determine the corresponding heating method, based on the determined working mode.

[0058] This invention proposes a control method for a cooking appliance and the cooking appliance itself. It aims to improve upon existing hybrid heating cooking appliances, which suffer from a single hybrid heating method, numerous limitations in usage environments, poor user experience, and inability to achieve prolonged hybrid heating.

[0059] Please see Figure 1-2 In one embodiment of the present invention, the cooking appliance 100 includes a main body 1, an electric heating device 2, an electromagnetic heating device 3, and a control device 4. The main body 1 includes a panel 11 with a heating area on its upper side. The electric heating device 2 is disposed within the main body 1 and includes at least two heating elements arranged in sections. The electromagnetic heating device 3 is disposed within the main body 1 and located on the side of the heating element opposite to the panel 11. The electromagnetic heating device 3 includes at least one coil assembly. The control device 4 is electrically connected to the electric heating device 2 and the electromagnetic heating device 3 to control at least two of the heating elements to work independently and to control the electromagnetic heating device 3 to work. The control device 4 includes a memory, a processor, and a control program for the cooking appliance 100 stored in the memory and executable on the processor. The control program for the cooking appliance 100 is configured to implement the steps of the above-described control method for the cooking appliance.

[0060] In the technical solution of this invention, the cooking appliance 100 is equipped with the electric heating device 2. To ensure the heating performance of the electric heating device 2, it is positioned close to the heating area of ​​the panel 11, so that the two heating elements are close to the heating area. When the cooking appliance 100 only needs to heat the pot in the heating area using electric heating, the control device 4 controls at least one of the two heating elements to operate, so that the heating element heats the pot in the heating area independently. Simultaneously, the cooking appliance 100 is also equipped with the electromagnetic heating device 3, which is located below the electric heating device 2. When the pot in the heating area has high coupling performance, the cooking appliance 100 can use only electric heating... The cookware in the heating area is heated by electromagnetic heating. At this time, the coil assembly is energized, and the control device 4 controls the coil assembly to work. The coil assembly generates an electromagnetic field that can pass upward through the electric heating device 2 to couple with the cookware in the heating area, thereby providing electromagnetic heating function to the heating area. When the electric heating device 2 and the electromagnetic heating device 3 need to be heated in combination, the control device 4 controls at least one of the two heating elements to work and controls the coil assembly to work, so that the heating elements and the coil assembly work simultaneously for at least a period of time, thereby increasing the heating power of the cooking appliance 100 and enabling the cooking appliance 100 to achieve high-power heating for a long time.

[0061] It should be noted that the two heating elements include a first heating element 21 and a second heating element 22. In order to ensure that the first heating element 21 and the second heating element 22 can work independently without affecting the other heating element, in a further embodiment of the present invention, the first heating element 21 and the second heating element 22 are arranged in parallel. This arrangement enables the control device 4 to control the first heating element 21 and the second heating element 22 to work independently, thereby ensuring the normal operation of the mixed heating function of the cooking appliance 100.

[0062] Similarly, the present invention does not limit the specific arrangement of the first heating element 21 and the second heating element 22. In one embodiment of the present invention, the first heating element 21 and the second heating element 22 can be arranged at intervals in a certain horizontal direction.

[0063] In another embodiment of the present invention, the second heating element 22 can be annular in shape and arranged around the periphery of the first heating element 21. This arrangement allows both the first heating element 21 and the second heating element 22 to be more accurately aligned with the heating area of ​​the panel 11, thereby improving the heating efficiency of the electric heating device 2.

[0064] In another embodiment of the present invention, the first heating element 21 can be annular in shape and disposed around the second heating element 22. This arrangement also improves the heating efficiency of the electric heating device 2.

[0065] Specifically, the specific shape and arrangement of the first heating element 21 and the second heating element 22 can be selected according to the requirements during actual installation, and the present invention does not impose any restrictions on this.

[0066] It should also be noted that the present invention does not limit the specific number of the heating elements. In another embodiment of the present invention, there are three heating elements, and the three heating elements further include a third heating element, which is spaced apart from the first heating element 21 and the second heating element 22.

[0067] In other embodiments of the present invention, the number of heating elements may be set to four or other numbers, which can be selected according to the actual needs.

[0068] It should also be noted that, in order to improve the heating efficiency of the cooking appliance 100 when performing mixed heating, the heating area of ​​the electromagnetic heating device 3 can be further increased. In one embodiment of the present invention, the coil assembly includes a first coil assembly 31, which is arranged around the periphery of the two heating parts and is at least arranged upward to correspond to the heating area, so as to be able to electromagnetically heat the cookware. It is understood that in this embodiment, the first coil assembly 31 is arranged around the electric heating device 2, that is, the first coil assembly 31 and the electric heating device 2 are misaligned. With this arrangement, if the cooking appliance 100 needs to perform mixed heating, the control device 4 can control the first coil assembly 31 to work. The electromagnetic field generated by the first coil assembly 31 can be directed upwards around the electric heating device 2 to couple with the pot in the heating area, providing electromagnetic heating function to the heating area. At the same time, the control device 4 can also control the first heating part 21 and the second heating part 22 to work simultaneously to electrically heat the heating area of ​​the panel 11. At this time, since the first coil assembly 31 and the electric heating device 2 are misaligned, only a small portion of the heat generated by the electric heating device 2 will be conducted to the first coil assembly 31, which will not cause a sharp increase in the temperature of the first coil assembly 31. This can further improve the heating efficiency of the cooking appliance 100 while ensuring the service life of the first coil assembly 31.

[0069] Of course, the present invention does not limit the specific shape of the first coil assembly 31. In one embodiment of the present invention, the first coil assembly 31 is rectangular; in another embodiment of the present invention, the first coil assembly 31 is annular, in which case the first coil assembly 31 is located on the periphery of the electric heating device 2.

[0070] Specifically, in this embodiment, the first coil assembly 31 is arranged in a ring shape.

[0071] It is understood that the first coil assembly 31 is composed of multiple turns of coil wound together. The present invention does not limit the arrangement of the multiple turns of coil in the first coil assembly 31. In one embodiment of the present invention, the first coil assembly 31 includes multiple turns of coil arranged in layers along the vertical direction. With this arrangement, since the multiple turns of coil are all arranged vertically, the first coil assembly 31 occupies less space horizontally, thereby reducing the horizontal size of the cooking appliance 100 and optimizing the miniaturization of the cooking appliance 100.

[0072] In another embodiment of the present invention, the first coil assembly 31 includes multiple turns of coil arranged in layers from the inside out. With this arrangement, all the multiple turns of coil are on the same horizontal plane, and since the first coil assembly 31 is arranged at least upwards to correspond to the heating area, the multiple turns of the first coil assembly 31 are all located close to the heating area of ​​the panel 11. When the control device 4 controls the first coil assembly 31 to operate, the first coil assembly 31 can further improve the electromagnetic heating efficiency, thereby improving the heating efficiency of the cooking appliance 100.

[0073] To further improve the heating efficiency of the cooking appliance 100 during mixed heating, in one embodiment of the present invention, the coil assembly is configured as a plurality of coil assemblies, and the plurality of coil assemblies further includes a second coil assembly 32. The second coil assembly 32 is located below the second heating part 22 and is at least partially offset from the first heating part 21. The first coil assembly 31 is located around the second coil assembly 32. With this configuration, when the electric heating device 2 and the electromagnetic heating device 3 are used for combined heating, the control device 4 controls the second coil assembly 32 to work and controls the first heating element 21 to work. At this time, the first heating element 21 and the second coil assembly 32 are at least partially misaligned. Only a portion of the heat generated by the first heating element 21 can be conducted to the surface of the second coil assembly 32, reducing the impact of the electric heating device 2 on the temperature rise of the second coil assembly 32. This alleviates the overheating problem caused by the heat transferred downward by the electric heating device 2 combined with the heat generated by the second coil assembly 32 itself. This reduces the probability of damage to the insulation layer of the second coil assembly 32, alleviates the overheating problem of the second coil assembly 32, protects the second coil assembly 32 from burning out, increases the service life of the second coil assembly 32, and improves the heating power of the cooking appliance 100.

[0074] Of course, in another embodiment of the present invention, the second heating element 22 may be at least partially misaligned with the second coil assembly 32. Thus, in this embodiment, if the cooking appliance 100 needs to perform mixed heating on the heating area on the panel 11, the control device 4 controls the second heating element 22 to work independently and simultaneously controls the second coil assembly 32 to work. Since the second heating element 22 and the second coil assembly 32 are at least partially misaligned, only a portion of the heat generated by the second heating element 22 can be transferred to the second coil assembly 32. The probability of the second coil assembly 32 overheating is reduced, and the service life of the second coil assembly 32 is increased.

[0075] Of course, in another embodiment of the present invention, the second coil assembly 32 can also be configured to be at least partially offset from both the first heating element 21 and the second heating element 22. With this configuration, when the cooking appliance 100 needs to perform mixed heating on the heating area on the panel 11, the control device 4 controls the second coil assembly 32 to work. At the same time, it can also control either the first heating element 21 or the second heating element 22 to work independently. Since both heating elements are at least partially offset from the second coil assembly 32, no matter which heating element is controlled to work, only a portion of the heat emitted by that heating element can be transferred to the second coil assembly 32, thereby reducing the influence of the heating element on the temperature of the second coil assembly 32 and improving the service life of the second coil assembly 32.

[0076] Specifically, in this invention, the second coil assembly 32 is at least partially offset from the first heating element 21.

[0077] In order to ensure the heating efficiency of the second coil assembly 32 while stabilizing its temperature, in a specific embodiment of the present invention, the projected area of ​​the second coil assembly 32 on the horizontal plane is A, and the projected area of ​​the portion of the second coil assembly 32 that is staggered from the first heating part 21 on the horizontal plane is B, where B ≥ 0.5A.

[0078] In a preferred embodiment of the present invention, the second coil assembly 32 is completely offset from the first heating element 21, i.e., B=A. In this way, the heat generated by the electric heating device 2 can have a minimal impact on the temperature of the second coil assembly 32.

[0079] Of course, in this invention, the second coil assembly 32 and the first coil assembly 31 can work independently without affecting each other. In one embodiment of the invention, the control device 4 can control only the second coil assembly 32 to work; in another embodiment of the invention, the control device 4 can also control only the first coil assembly 31 to work; in yet another embodiment of the invention, the control device 4 can also control both the second coil assembly 32 and the first coil assembly 31 to work simultaneously, and the second coil assembly 32 and the first coil assembly 31 work independently respectively.

[0080] Furthermore, to further enhance the heating method of the cooking appliance 100, in one embodiment of the present invention, the plurality of coil assemblies further include a third coil assembly 33, which is located below the first heating element 21 and is at least partially offset from the second heating element 22, and is located between the first coil assembly 31 and the second coil assembly 32. With this configuration, when the electric heating device 2 and the electromagnetic heating device 3 are used for combined heating, the control device 4 controls the third coil assembly 33 to operate and controls the second heating element 22 to operate. At this time, the second heating element 22 and the third coil assembly 33 are at least partially misaligned. Only a portion of the heat generated by the second heating element 22 can be conducted to the surface of the third coil assembly 33, reducing the impact of the electric heating device 2 on the temperature rise of the third coil assembly 33. This alleviates the overheating problem caused by the heat transferred downward by the electric heating device 2 being superimposed on the heat generated by the third coil assembly 33 itself, thereby reducing the probability of damage to the insulation layer of the third coil assembly 33. This can alleviate the overheating problem of the third coil assembly 33, protect the third coil assembly 33 from burning out, increase the service life of the electromagnetic heating device 3, and improve the heating power of the cooking appliance 100.

[0081] Similarly, to ensure that the first coil assembly 31, the second coil assembly 32, and the third coil assembly 33 can all operate independently without affecting the other coil assemblies, in one embodiment of the present invention, the first coil assembly 31, the second coil assembly 32, and the third coil assembly 33 are arranged in parallel, so that the control device 4 can control the first coil assembly 31, the second coil assembly 32, and the third coil assembly 33 to operate independently. This ensures the normal operation of the mixed heating function of the cooking appliance 100.

[0082] It should also be noted that, in order to further maintain the temperature of the electromagnetic heating device 3 and alleviate its rapid temperature rise, in one embodiment of the present invention, the cooking appliance 100 further includes a fan 5, which is disposed inside the main body and located below the electromagnetic heating device 3. The fan 5 is used to blow on the electromagnetic heating device 3 to maintain the temperature of the electromagnetic heating device 3.

[0083] Furthermore, in this invention, to facilitate user operation of the cooking appliance 100, the cooking appliance 100 also includes an operating device 6, which is provided with buttons for user operation, allowing the user to control the electric heating device 2 and the electromagnetic heating device 3.

[0084] The present invention also proposes a method for controlling a cooking appliance, which is based on the cooking appliance 100 described above. Please refer to [link to relevant documentation]. Figure 3 In a first embodiment of the present invention, the method for controlling the cooking appliance includes:

[0085] S100: When the cooking appliance 100 is in the on state and receives a working instruction, determine the working mode of the cooking appliance 100 according to the working instruction.

[0086] It is understood that the cooking appliance 100 can receive the working instructions only when the cooking appliance 100 is in the "on" state, and the working instructions are of various kinds, with the various different working instructions used to determine different working modes of the cooking appliance 100.

[0087] S200. According to the operating mode, control the corresponding heating element and / or the coil assembly to operate.

[0088] The heating element and coil assembly of the cooking appliance 100 need to work differently in different working modes. Only after the working mode is determined can the working element and / or coil assembly corresponding to the working mode be controlled to ensure the accuracy of the heating method and protect the user experience.

[0089] In the technical solution of the present invention, the cooking appliance 100 is equipped with the electric heating device 2. To ensure the heating performance of the electric heating device 2, it is positioned close to the heating area of ​​the panel 11, so that the two heating parts are close to the heating area. Simultaneously, an electromagnetic heating device 3 is provided. The coil assembly in the electromagnetic heating device 3 is energized to generate an electromagnetic field. The electromagnetic field generated by the coil assembly can pass upward through the electric heating device 2 to couple with the pot in the heating area, providing electromagnetic heating to the heating area. This achieves the desired heating performance of the electric heating device 2 and the... The electromagnetic heating device 3, in conjunction with the cooking appliance 100 when it is in the on state, sends a working command to the cooking appliance 100. This working command has multiple variations, each used to determine a different working mode, enabling the cooking appliance 100 to employ various heating methods. Upon receiving the working command, the cooking appliance 100 determines the working mode, i.e., the corresponding heating method, based on the determined working mode. Then, according to the determined working mode, it controls the operation of the corresponding heating element and / or the coil assembly. This configuration allows the electric heating device 2 and the electromagnetic heating device 3 to work together, enabling the cooking appliance 100 to achieve multiple different heating modes under varying environmental conditions through the control of both electric and electromagnetic heating, and ensuring that the cooking appliance 100 can achieve prolonged heating in each mode.

[0090] It should be noted that when the heating element and the coil assembly operate simultaneously, the heat from the heating element is easily conducted to the coil assembly, causing its temperature to rise. Furthermore, the coil assembly itself also generates heat during operation, leading to an increase in its temperature. This cumulative heat can easily damage the coil assembly. Therefore, to ensure that the cooking appliance 100 can achieve prolonged heating in each mode, please refer to [link to relevant documentation]. Figure 4 In the second embodiment of the present invention, step S200 includes:

[0091] S210. When the working mode is a combination mode, the coil assembly and the heating element, which are set in a staggered manner, are controlled to work simultaneously for at least a period of time.

[0092] In the technical solution of this embodiment, when the working mode of the cooking appliance 100 is determined to be the combined mode, the control device 4 can control the coil assembly to work and control one of the two heating elements to work. At this time, the independently working heating element is at least partially misaligned with the coil assembly. Only a portion of the heat generated when the heating element is working can be conducted to the surface of the coil assembly, so as to reduce the influence of the electric heating device 2 on the temperature rise of the coil assembly. This alleviates the overheating problem caused by the heat transmitted downward by the electric heating device 2 plus the heat generated by the coil assembly itself, thereby reducing the probability of damage to the insulation layer of the coil assembly. While protecting the coil assembly from damage, it ensures that the cooking appliance 100 can achieve long-term, high-power heating in the combined mode.

[0093] Of course, in this invention, when the working mode of the cooking appliance 100 is the combined mode, the cooking appliance 100 still has multiple heating methods. Please refer to [link / reference]. Figure 5 For example, in the third embodiment of the present invention, step S210 includes:

[0094] S211. When the working mode is the first combination mode, the first coil assembly 31, the first heating element 21 and / or the second heating element 22 are controlled to work simultaneously for at least a period of time.

[0095] In the technical solution of this embodiment, when the working mode of the cooking appliance 100 is the first combination mode, the first coil assembly 31 operates. Since the first coil assembly 31 is arranged around the periphery of the two heating elements (i.e., the first coil assembly 31 is misaligned with the first heating element 21 and / or the second heating element 22), when the first coil assembly 31 operates, the electromagnetic field generated by the first coil assembly 31 can bypass the first heating element 21 and / or the second heating element 22 upwards to couple with the pot in the heating area, providing electromagnetic heating to the heating area. Simultaneously, the... When the first heating element 21 and / or the second heating element 22 are in operation, they electrically heat the heating area. At this time, since the first coil assembly 31 is misaligned with the first heating element 21 and / or the second heating element 22, only a small portion of the heat generated by the first heating element 21 and / or the second heating element 22 is conducted to the first coil assembly 31, which will not cause a sharp increase in the temperature of the first coil assembly 31. This ensures the service life of the first coil assembly 31 while expanding the heating methods of the cooking appliance 100, and ensures the long-term high-power heating operation of the cooking appliance 100.

[0096] It is understood that, in this embodiment, the present invention does not limit which of the first heating element 21 and the second heating element 22 operates. For example, in one embodiment of the present invention, when the operating mode is the first combination mode, the first coil assembly 31 and the first heating element 21 are controlled to operate simultaneously for at least a period of time; in another embodiment of the present invention, when the operating mode is the first combination mode, the first coil assembly 31 and the second heating element 22 are controlled to operate simultaneously for at least a period of time; in yet another embodiment of the present invention, when the operating mode is the first combination mode, the first coil assembly 31, the first heating element 21, and the second heating element 22 are controlled to operate simultaneously for at least a period of time.

[0097] It should be further noted that, in this invention, when the working mode of the cooking appliance 100 is the combined mode, the cooking appliance 100 may also have other heating methods. Please refer to [link / reference needed]. Figure 6 In the fourth embodiment of the present invention, step S210 includes:

[0098] S212. When the working mode is the first combination mode, the first coil assembly 31, the second coil assembly 32 and the first heating element 21 are controlled to work simultaneously for at least a period of time.

[0099] In this embodiment, when the cooking appliance 100 is in the first combination mode, the first coil assembly 31 and the second coil assembly 32 operate. Since the first coil assembly 31 is positioned around the periphery of the two heating elements, and the second coil assembly 32 is located below the second heating element 22, meaning both the first coil assembly 31 and the second coil assembly 32 are at least partially offset from the first heating element 21, when the first coil assembly 31 operates, the electromagnetic field generated by the first coil assembly 31 can bypass the first heating element 21 upwards, and the electromagnetic field generated by the second coil assembly 32 can pass upwards through the electric heating device 2, thus interacting with the heating area. The cookware is coupled at the point of contact, providing electromagnetic heating to the heating area. Simultaneously, the first heating element 21 operates to electrically heat the heating area. At this time, since the first coil assembly 31 and the second coil assembly 32 are at least partially misaligned with the first heating element 21, only a small portion of the heat generated by the first heating element 21 is conducted to the first coil assembly 31 and the second coil assembly 32, preventing a sharp increase in the temperature of the first coil assembly 31 and the second coil assembly 32. This expands the heating methods of the cooking appliance 100 while ensuring the service life of the first coil assembly 31 and the second coil assembly 32, and ensuring the long-term high-power heating operation of the cooking appliance 100.

[0100] It should be further noted that, in this invention, when the operating mode of the cooking appliance 100 is the combined mode, the cooking appliance 100 may also have another heating method. Please refer to [link / reference needed]. Figure 7 In the fifth embodiment of the present invention, step S210 includes:

[0101] S213. When the working mode is the first combination mode, the first coil assembly 31, the third coil assembly 33 and the second heating element 22 are controlled to work simultaneously for at least a period of time.

[0102] In this embodiment, when the cooking appliance 100 is in the first combination mode, the first coil assembly 31 and the third coil assembly 33 operate. Since the first coil assembly 31 is positioned around the periphery of the two heating elements, and the third coil assembly 33 is located below the second heating element 22, meaning both the first coil assembly 31 and the third coil assembly 33 are at least partially offset from the second heating element 22, when the first coil assembly 31 operates, the electromagnetic field generated by it can bypass the second heating element 22 upwards, and the electromagnetic field generated by the third coil assembly 33 can pass upwards through the electric heating device 2, thus interacting with the heating area. The cookware is coupled at the point of contact, providing electromagnetic heating to the heating area. Simultaneously, the second heating element 22 operates to electrically heat the heating area. At this time, since the first coil assembly 31 and the third coil assembly 33 are at least partially misaligned with the second heating element 22, only a small portion of the heat generated by the second heating element 22 is conducted to the first coil assembly 31 and the third coil assembly 33, preventing a sharp increase in the temperature of the first coil assembly 31 and the third coil assembly 33. This expands the heating methods of the cooking appliance 100 while ensuring the service life of the first coil assembly 31 and the third coil assembly 33, and ensuring the long-term high-power heating operation of the cooking appliance 100.

[0103] Furthermore, in this invention, when the operating mode of the cooking appliance 100 is the combined mode, the control device 4 may not control the first coil assembly 31 to operate. (See also...) Figure 8 In the sixth embodiment of the present invention, step S210 includes:

[0104] S214. When the working mode is the second combination mode, the second coil assembly 32 and the first heating element 21 are controlled to work simultaneously for at least a period of time.

[0105] In this embodiment, when the cooking appliance 100 is in the second combination mode, the second coil assembly 32 operates. Since the second coil assembly is located below the second heating element 22 (i.e., the second coil assembly 32 and the first heating element 21 are at least partially misaligned), when the second coil assembly 32 operates, the electromagnetic field generated by the second coil assembly 32 can pass upwards through the electric heating device 2 to couple with the pot in the heating area, providing electromagnetic heating to the heating area. Simultaneously, the control device 4 controls the first heating element 21 to operate independently. The first heating element 21 and the first coil assembly 31 are at least partially misaligned. When the first heating element 21 is working, only a portion of the heat generated can be conducted to the surface of the first coil assembly 31, reducing the impact of the first heating element 21 on the temperature rise of the second coil assembly 32. This alleviates the overheating problem caused by the heat transferred downward by the electric heating device 2 combined with the heat generated by the second coil assembly 32 itself. This reduces the probability of damage to the insulation layer of the second coil assembly 32, protects the second coil assembly 32 from being burned out, and improves the heating power and heating time of the cooking appliance 100.

[0106] It should be noted that when the cooking appliance 100 operates in a combined mode, the heating power and heating effect of the electric heating device 2 and the electromagnetic heating device 3 differ. This can easily lead to uneven heating of multiple areas on the surface of the cookware within the heating zone. Therefore, to reduce the heating blind spots of the cooking appliance 100 and achieve uniform and stable heating in a certain area on the surface of the cookware, please refer to [link to relevant documentation]. Figure 9 In the seventh embodiment of the present invention, step S210 includes:

[0107] S215. When the working mode is the third combination mode, the coil assembly and the heating element, which are set in a staggered manner, are controlled to work simultaneously for at least a period of time with a preset power ratio; wherein, the preset power ratio of the coil assembly and the heating element is A, 0.6≤A≤1.3.

[0108] In the technical solution of the present invention, when the working mode of the cooking appliance 100 is determined to be the third combination mode, the control device 4 can control the coil assembly to work and control one of the two heating elements to work. At this time, the independently working heating element and the coil assembly are at least partially misaligned. Only a portion of the heat generated by the heating element can be conducted to the surface of the coil assembly, so as to reduce the influence of the electric heating device 2 on the temperature rise of the coil assembly. At the same time, since the preset power ratio of the coil assembly and the heating element is A, 0.6≤A≤1.3, the heating element can add heat to the part of the heating area where the coil assembly has a lower heating temperature by electric heating, thereby increasing the temperature of that part in the heating area and maintaining the uniformity of the temperature in the heating area. This maintains a more uniform temperature distribution on the surface of the cookware corresponding to the heating area, enabling the surface of the cookware to achieve uniform and stable heating, thereby further expanding the application scenarios of the cooking appliance 100 and enhancing the use value of the product.

[0109] It should be noted that the present invention does not limit the specific power values ​​of the coil assembly and the heating element, but only requires that the power ratio of the coil assembly and the heating element be within the range of the preset power ratio. In actual settings, the power ratio can be selected according to the actual situation.

[0110] When a user uses the cooking appliance 100, the user typically adjusts the heating power of the cooking appliance 100 according to the actual usage scenario. To ensure that the cooking appliance 100 can still provide uniform heating to the pot within a certain range after the user adjusts the heating power, please refer to [the relevant documentation / reference needed]. Figure 10 In the eighth embodiment of the present invention, after step S215, the method further includes:

[0111] S216. When the cooking appliance 100 is in the third combination mode and receives an adjustment command, the power ratio of the coil assembly and the heating element, which are set in a staggered manner, is adjusted according to the adjustment command; wherein, the adjusted power ratio of the coil assembly and the heating element is B, 0.8A≤B≤1.2A, and 0.6≤B≤1.3.

[0112] In the technical solution of this embodiment, when the working mode of the cooking appliance 100 is the third combination mode, the adjustment command is sent to the cooking appliance 100. The adjustment command includes at least a power increase adjustment command and a power decrease adjustment command, so as to increase or decrease the power of the cooking appliance 100. After the cooking appliance 100 receives the adjustment command, it can adjust the power of the coil assembly and the heating element according to the adjustment command. At this time, the adjustment range of the power of the coil assembly and the heating element may be different. Therefore, the power ratio of the coil assembly and the heating element may also change. The adjusted power ratio of the coil assembly and the heating element is maintained so that the adjusted power ratio B is between 0.8A and 1.2A, and between 0.6 and 1.3. This configuration ensures the efficiency of the heating element in replenishing the heat to the lower-temperature portion of the coil assembly in the heating area, so that the cooking appliance 100 can maintain a uniform temperature in the heating area even after power adjustment. This maintains a more uniform temperature distribution on the surface of the cookware corresponding to the heating area, ensuring that the cooking appliance 100 heats a certain area of ​​the cookware surface evenly and stably.

[0113] It is understood that the cooking appliance 100 may also control only one of the heating element and the coil assembly to operate; please refer to [link / reference]. Figure 11 For example, in the ninth embodiment of the present invention, step S200 includes:

[0114] S220. When the working mode is the standby mode, the coil assembly or the heating element is controlled to work independently for a period of time.

[0115] It is understandable that when the magnetic conductivity of the cookware in the heating area is poor, the control device 4 only controls the coil assembly to work, and the heating element does not work, so that the cooking appliance 100 performs electromagnetic heating alone; while when the magnetic conductivity of the cookware in the heating area is good, the control device 4 only controls the heating element to work, and the coil assembly does not work, so that the cooking appliance 100 performs electric heating alone.

[0116] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
