Description

Technical Field

[0001] The present invention belongs to the technical field of cooking equipment, and in particular, relates to a cooking device, a control method for a cooking device, a control device for a cooking device, and a readable storage medium. Background Art

[0002] With the diversification of induction cooker glass panels, induction cookers currently use two types of glass spliced ​​together as panels, and add connectors as the link between the two types of glass. However, if the pot is offset, the higher temperature of the pot can easily cause the connectors to melt, thereby bringing the risk of water ingress. The electrical components inside the induction cooker are easily damaged by moisture or short-circuited, which not only increases the damage rate of the induction cooker, but also brings safety risks to users. Summary of the Invention

[0003] The present invention aims to solve one of the technical problems existing in the prior art or related art.

[0004] In view of this, in a first aspect, the present invention proposes a cooking device, comprising: a first panel, wherein a mounting hole is provided on the first panel; a second panel, located in the mounting hole, the first panel and the second panel being used to support cooking utensils; a heating element, at least a portion of which is located below the second panel, the heating element being used to heat the cooking utensils; a splicing piece, connected to the first panel and / or the second panel, the splicing piece being used to connect the first panel and the second panel; a first temperature sensor, located below the second panel, the first temperature sensor being used to collect the temperature of the second panel; a second temperature sensor, located below the first panel and / or the second panel, the second temperature sensor being used to collect the temperature of the first panel and / or the second panel, the distance between the first temperature sensor and the side of the second panel being L1, the distance between the second temperature sensor and the side of the second panel being L2, L1>L2; wherein the operating power of the heating element is associated with the temperature of the first panel and the temperature of the second panel.

[0005] When the second panel is installed in the mounting hole, the first and second panels are combined to form a spliced ​​panel. The second panel is located near the center of the spliced ​​panel. When using the cooking device, cooking utensils need to be placed in the center of the spliced ​​panel. Therefore, when the cooking utensils are placed in the correct position, the cooking utensils are mainly supported by the second panel. The splicing piece is provided at the splicing position of the first and second panels, and is used to connect the first and second panels to ensure the structural stability of the spliced ​​panel.

[0006] The heating element needs to heat the cooking utensils. Since the cooking utensils need to be placed on the second panel, at least a portion of the heating element needs to be placed below the second panel so that the heating element can stably heat the cooking utensils. For example, all of the heating elements can be installed below the second panel, or a portion of the heating elements can be placed below the first panel and another portion of the heating elements can be placed below the second panel.

[0007] The first temperature sensor is positioned below the second panel so that the second temperature sensor can detect the temperature of the second panel. The first temperature sensor is spaced farther apart from the side of the second panel than the second temperature sensor. Therefore, the second temperature sensor is positioned closer to the edge of the second panel, enabling it to detect the temperature near the junction of the first and second panels. The first temperature sensor can be positioned closer to the center of the second panel.

[0008] During the heating process, the temperature of the cooking appliance is high. If the cooking appliance is misaligned, parts of the cooking appliance may come into contact with the splicing parts, causing the splicing parts to melt. The misalignment of the cooking appliance can be determined based on the temperature change values ​​detected by the first temperature sensor and the second temperature sensor, and the operating power of the heating element can be adjusted accordingly.

[0009] For example, during the heating process of a cooking utensil, if the cooking utensil is not misplaced or is slightly misplaced, the first temperature sensor will register a higher temperature value because it is close to the center of the second panel, while the second temperature sensor will register a lower temperature value because it is not close to the cooking utensil. If the cooking utensil is misplaced, the second temperature sensor will register a relatively higher temperature value, while the first temperature sensor will register a relatively lower temperature value. Therefore, based on the temperature change values ​​registered by the first and second temperature sensors, it can be determined whether the cooking utensil is misplaced. When the cooking utensil is accurately placed or slightly misplaced, there is no need to change the operating power of the heating element. However, if the cooking utensil is misplaced, the operating power of the heating element will need to be reduced or stopped to prevent the cooking utensil from melting the spliced ​​components.

[0010] The above method can quickly and accurately detect the deviation of cooking utensils, solve the problem of insufficient temperature resistance of splicing panels and melting of splicing parts caused by the deviation of cooking utensils, and reduce the risk of water intrusion into cooking equipment.

[0011] In addition, the cooking device in the above technical solution provided by the present invention may also have the following additional technical features:

[0012] In some technical solutions, optionally, the position of the second temperature sensor is opposite to the position where the first panel and the second panel are attached.

[0013] When the cooking utensil is placed in the middle of the second panel, or is slightly offset from the middle of the second panel, the cooking utensil is in the correct position. If the cooking utensil is close to the junction of the first and second panels, the cooking utensil is not correctly placed, that is, the cooking utensil is offset.

[0014] The second temperature sensor is installed at a position corresponding to the joint position of the first panel and the second panel, so that the second temperature sensor can detect the temperature at the joint position of the first panel and the second panel. If the cooking utensil is placed in an offset position, the temperature at the joint position of the first panel and the second panel will rise rapidly. Therefore, the above-mentioned installation position of the second temperature sensor can improve the accurate detection of whether the cooking utensil is offset.

[0015] Of course, in other embodiments, the second temperature sensor can also be positioned below the second panel or below the first panel. However, if the second temperature sensor is positioned only below the second panel, the proximity of the second temperature sensor to the cooking utensils will result in a higher temperature value being recorded by the second temperature sensor, even if the cooking utensils are not misplaced. This may reduce the accuracy of detecting misplaced cooking utensils. If the second temperature sensor is positioned only below the first panel, the proximity of the second temperature sensor to the cooking utensils will result in a smaller change in the temperature value recorded by the second temperature sensor, even if the cooking utensils are misplaced. This also makes it difficult to improve detection accuracy. Therefore, positioning the second temperature sensor at the junction of the first and second panels can improve the accuracy of detecting misplaced cooking utensils.

[0016] In some technical solutions, optionally, the second temperature sensor includes a plurality of temperature measuring probes, which are used to collect the temperature of the first panel and / or the second panel, and the plurality of temperature measuring probes are distributed at intervals along the circumference of the second panel.

[0017] When a cooking appliance is placed, it may shift in any direction. If multiple temperature probes are arranged around the second panel, any shift in the cooking appliance will result in a significant temperature change being detected by a corresponding temperature probe, thereby confirming the shift. By increasing the number of temperature probes used, the accuracy of detecting whether the cooking appliance has shifted can be improved.

[0018] In some technical solutions, optionally, the second temperature sensor has a first side and a second side, the first side and the second side are arranged opposite to each other, the spacing between the first side and the side of the second panel is L3, the spacing between the second side and the side of the second panel is L4, and the difference between L3 and L4 is set to L5, L5≤40mm.

[0019] The installation position of the second temperature sensor corresponds to the position where the first panel and the second panel are spliced. The center line of the second temperature sensor can be directly opposite the side of the second panel, or the center line of the second temperature sensor can be offset to a certain extent compared to the side of the second panel.

[0020] The two opposing sides of the second temperature sensor are the first side portion and the second side portion, respectively. When the midline of the second temperature sensor is aligned with the side portion of the second panel, the first and second side portions are spaced equal distances from the side portion of the second panel, namely, L3 and L4. If the midline of the second temperature sensor is offset relative to the side portion of the second panel, L3 may be greater than L4 or less than L4. To prevent the second temperature sensor from being excessively offset, the installation range of the second temperature sensor must be limited.

[0021] The maximum offset distance of the first side or the second side compared to the side of the second panel is 20 mm. In this case, the maximum difference between L3 and L4 is 40 mm. In this case, excessive offset of the second temperature sensor can be avoided, ensuring that the temperature value collected by the second temperature sensor can be used to accurately detect whether the cooking utensil is offset.

[0022] In some technical solutions, optionally, the first temperature sensor includes an infrared temperature sensor; and / or the second temperature sensor includes an infrared temperature sensor.

[0023] In a second aspect, the present invention proposes a control method for a cooking device, which is used for the cooking device in the first aspect. The control method for the cooking device includes: obtaining a first temperature change value collected by a first temperature sensor and a second temperature change value collected by a second temperature sensor; and controlling the operation of a heating element according to the first temperature change value and the second temperature change value.

[0024] The first temperature sensor is positioned below the second panel so that the second temperature sensor can detect the temperature of the second panel. The first temperature sensor is spaced farther apart from the side of the second panel than the second temperature sensor. Therefore, the second temperature sensor is positioned closer to the edge of the second panel, enabling it to detect the temperature near the junction of the first and second panels. The first temperature sensor can be positioned closer to the center of the second panel.

[0025] During the heating process, the temperature of the cooking appliance is high. If the cooking appliance is misaligned, parts of the cooking appliance may come into contact with the splicing parts, causing the splicing parts to melt. The misalignment of the cooking appliance can be determined based on the temperature change values ​​detected by the first temperature sensor and the second temperature sensor, and the operating power of the heating element can be adjusted accordingly.

[0026] For example, during the heating process of a cooking utensil, if the cooking utensil is not misplaced or is slightly misplaced, the first temperature sensor will register a higher temperature value because it is close to the center of the second panel, while the second temperature sensor will register a lower temperature value because it is not close to the cooking utensil. If the cooking utensil is misplaced, the second temperature sensor will register a relatively higher temperature value, while the first temperature sensor will register a relatively lower temperature value. Therefore, based on the temperature change values ​​registered by the first and second temperature sensors, it can be determined whether the cooking utensil is misplaced. When the cooking utensil is accurately placed or slightly misplaced, there is no need to change the operating power of the heating element. However, if the cooking utensil is misplaced, the operating power of the heating element will need to be reduced or stopped to prevent the cooking utensil from melting the spliced ​​components.

[0027] The above method can quickly and accurately detect the deviation of cooking utensils, solve the problem of insufficient temperature resistance of splicing panels and melting of splicing parts caused by the deviation of cooking utensils, and reduce the risk of water intrusion into cooking equipment.

[0028] In some technical solutions, optionally, a first temperature change value collected by the first temperature sensor and a second temperature change value collected by the second temperature sensor are obtained, including: when the heating element is running, obtaining the first temperature value collected by the first temperature sensor and the second temperature value collected by the second temperature sensor; when the time after collecting the first temperature value and the second temperature value reaches a set time, obtaining the third temperature value collected by the first temperature sensor and the fourth temperature value collected by the second temperature sensor, the difference between the third temperature value and the first temperature value is the first temperature change value, and the difference between the fourth temperature value and the second temperature value is the second temperature change value.

[0029] During the cooking process, a processor in the cooking device first obtains a first temperature value collected by a first temperature sensor and a second temperature value collected by a second temperature sensor. After a period of heating, the temperature values ​​collected by the first and second temperature sensors change, at which point a third temperature value collected by the first and fourth temperature sensors is obtained. If only the first or second temperature sensor is used to collect temperature change values, even if the cooking appliance is not misaligned, the temperature value collected by the first or second temperature sensor may be abnormal due to other factors. Therefore, combining the temperature change values ​​collected by the first and second temperature sensors can accurately determine whether the cooking appliance is misaligned, thereby improving detection accuracy and reducing the risk of false positives.

[0030] In some technical solutions, optionally, the operation of the heating element is controlled according to the first temperature change value and the second temperature change value, including: when the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, maintaining the operating power of the heating element unchanged, and the first set value is greater than or equal to the second set value; when the first temperature change value is greater than the first set value and the second temperature change value is greater than or equal to the second set value, controlling the operating power of the heating element according to the cooking mode of the cooking equipment.

[0031] During the heating process of the cooking utensil, if the placement position of the cooking utensil is not shifted or is slightly shifted, since the cooking utensil is close to the middle of the second panel, the temperature change collected by the first temperature sensor will be relatively large, and since the second temperature sensor is far away from the middle of the second panel, the temperature change collected by the second temperature sensor will be relatively small.

[0032] When obtaining the first temperature change value and the second temperature change value, if the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, the temperature change in the middle of the second panel is larger, and the temperature change in the edge area of ​​the second panel is smaller, which is consistent with the situation where the cooking utensil is placed accurately. Therefore, it is determined that the current cooking utensil has not been significantly displaced. At this time, the operating power of the heating element needs to be changed, and the current operating power can be maintained to continue heating the cooking utensil.

[0033] If the first temperature change value is greater than the first set value, and the second temperature change value is greater than or equal to the second set value, the temperature value change collected by the second temperature sensor is large, which means that the cooking utensil has been displaced. In this case, the adjustment method of the operating power of the heating element is determined based on the collected temperature change value and the cooking mode of the cooking equipment. By making targeted adjustments to the operating power of the heating element, stable heating of the cooking utensil can be guaranteed as much as possible, and the problem of melting of the spliced ​​parts can be avoided.

[0034] In some technical solutions, optionally, the operating power of the heating element is controlled according to the cooking mode of the cooking equipment, including: when the cooking mode is the first mode, adjusting the operating power of the heating element, wherein the operating power of the heating element is inversely proportional to the temperature value collected by the second temperature sensor; when the cooking mode is the second mode, controlling the heating element to stop operating; wherein the first mode includes any one of the following: steaming mode, soup mode, hot pot mode; the second mode includes any one of the following: stir-frying mode, frying mode, and grilling mode.

[0035] If the cooking appliance is misaligned, the heating element needs to be controlled according to the cooking mode of the cooking device. In cooking modes such as steaming, soup making, or hot pot, water is primarily used as the heating medium. When there is water in the cooking appliance, the temperature of the cooking appliance will not be too high. In this case, even if the cooking appliance is misaligned, it is unlikely to cause the joints to melt. In this case, the heating element can be controlled to continue cooking at the current operating power or reduced in power, thereby ensuring stable heating of the cooking appliance.

[0036] When there is water in the cooking container, the temperature of the cooking container is unlikely to continue to rise after reaching a certain value. If the water in the cooking container boils away, the temperature of the cooking container will rise rapidly. Therefore, in the first cooking mode, when the second temperature change value is greater than the second set value, as the temperature value collected by the second temperature sensor increases, the operating power of the heating element needs to be reduced accordingly to prevent damage to the cooking appliance due to dry cooking.

[0037] In cooking modes such as stir-fry mode, frying mode or grilling mode, the cooking appliance does not need water as a heating medium. The cooking appliance directly heats the food. As the cooking appliance is heated, the temperature of the cooking appliance will reach a higher temperature. If the cooking appliance is misaligned at this time, the cooking appliance may easily cause heat melting of the splicing parts. Therefore, in the second mode, if the cooking appliance is misaligned, the heating element is controlled to stop running, thereby stopping heating the cooking appliance.

[0038] In some technical solutions, optionally, according to the cooking mode of the cooking equipment, the operating power of the heating element is controlled, and it also includes: in the case of the first mode, based on the second temperature change value being greater than or equal to a third set value, controlling the heating element to stop operating, and the third set value is greater than the second set value.

[0039] When the cooking device is operating in the first mode, the temperature value recorded by the second temperature sensor increases, and the operating power of the heating element decreases accordingly. However, when the second temperature change value is greater than or equal to the third set value, it indicates that the temperature value recorded by the second temperature sensor has reached a high value. If the cooking device continues to heat at this time, the cooking device may cause the joint to melt. Therefore, it is necessary to control the heating element to stop operating to ensure the seal between the first panel and the second panel.

[0040] In some technical solutions, optionally, when the second temperature change value is obtained, the control method further includes: controlling the heating element to stop running when the temperature value collected by the first temperature sensor is greater than a fourth set value.

[0041] During the cooking process, it is necessary to judge whether the temperature value collected by the first temperature sensor reaches the fourth set value. If the temperature collected by the first temperature sensor reaches the fourth set value, it means that the current cooking appliance has reached a higher temperature. The fourth set value can be the limit temperature value set inside the cooking device. When this temperature value is reached, it means that the temperature of the cooking appliance is abnormal. At this time, it is necessary to control the heating element to stop running to ensure the safety of the cooking device during use.

[0042] In some technical solutions, optionally, controlling the operation of the heating element according to the first temperature change value and the second temperature change value also includes: controlling the heating element to stop operating when the first temperature change value is less than the first set value and the second temperature change value is greater than the second set value.

[0043] If the temperature change value detected by the first temperature sensor is less than the first set value, and the temperature change value detected by the second temperature sensor is greater than the second set value, it means that the cooking utensil is not heated normally. At this time, it can be determined that the cooking utensil is misaligned and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor. Heating needs to be stopped immediately to ensure the safety of the cooking equipment.

[0044] In some technical solutions, optionally, when the first temperature change value is less than the first set value, and the second temperature change value is greater than the second set value, the control method further includes: outputting a reminder message.

[0045] When it is determined that the cooking utensil is misaligned and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor, the cooking device outputs a reminder message to remind the user to deal with the problem of the current misalignment of the cooking utensil.

[0046] In a third aspect, the present invention proposes a control device for a cooking device, which is used for the cooking device as in the first aspect. The control device of the cooking device includes: an acquisition module, which is used to obtain a first temperature change value collected by a first temperature sensor and a second temperature change value collected by a second temperature sensor; and a control module, which is used to control the operation of a heating element according to the first temperature change value and the second temperature change value.

[0047] In some technical solutions, optionally, the acquisition module is specifically used to: when the heating element is running, obtain a first temperature value collected by the first temperature sensor and a second temperature value collected by the second temperature sensor; when the time after collecting the first temperature value and the second temperature value reaches a set time, obtain a third temperature value collected by the first temperature sensor and a fourth temperature value collected by the second temperature sensor, the difference between the third temperature value and the first temperature value is a first temperature change value, and the difference between the fourth temperature value and the second temperature value is a second temperature change value.

[0048] In some technical solutions, optionally, the control module is specifically used to: maintain the operating power of the heating element unchanged when the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, and the first set value is greater than or equal to the second set value; control the operating power of the heating element according to the cooking mode of the cooking equipment when the first temperature change value is greater than the first set value and the second temperature change value is greater than or equal to the second set value.

[0049] In some technical solutions, optionally, the control module is also used to: when the cooking mode is the first mode, adjust the operating power of the heating element, wherein the operating power of the heating element is inversely proportional to the temperature value collected by the second temperature sensor; when the cooking mode is the second mode, control the heating element to stop operating; wherein, the first mode includes any one of the following: steaming mode, soup mode, hot pot mode; the second mode includes any one of the following: stir-frying mode, frying mode, and grilling mode.

[0050] In some technical solutions, optionally, the control module is also used to: in the first mode, based on the second temperature change value being greater than or equal to a third set value, control the heating element to stop operating, and the third set value is greater than the second set value.

[0051] In some technical solutions, optionally, when the second temperature change value is obtained, the control module is further used to: control the heating element to stop running when the temperature value collected by the first temperature sensor is greater than a fourth set value.

[0052] In some technical solutions, optionally, the control module is further used to: control the heating element to stop operating when the first temperature change value is less than the first set value and the second temperature change value is greater than the second set value.

[0053] In some technical solutions, optionally, when the first temperature change value is less than the first set value, and the second temperature change value is greater than the second set value, the control module is further used to: output a reminder message.

[0054] In a fourth aspect, the present invention proposes a control device for a cooking appliance, comprising a memory and a processor, wherein the memory stores programs or instructions that can be run on the processor, and when the programs or instructions are executed by the processor, the steps of the control method in the second aspect are implemented.

[0055] In a fifth aspect, the present invention proposes a readable storage medium having a program or instruction stored thereon, wherein the program or instruction, when executed by a processor, implements the steps of the control method in the second aspect.

[0068] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0070] Refer to the following Figures 1 to 8 A cooking device, a cooking device control method, a cooking device control apparatus, and a readable storage medium according to some embodiments of the present invention are described.

[0071] Combine Figure 1 、 Figure 2 and Figure 3As shown, in an embodiment of the present invention, a cooking device is proposed, including: a first panel 110, a second panel 120, a heating element 130, a splicing piece 140, a first temperature sensor 150 and a second temperature sensor 160, the first panel 110 is provided with a mounting hole 111, the second panel 120 is located in the mounting hole 111, the first panel 110 and the second panel 120 are used to support the cooking utensil 170, at least a portion of the heating element 130 is located below the second panel 120, the heating element 130 is used to heat the cooking utensil 170, the splicing piece 140 is connected to the first panel 110 and / or the second panel 120, and the splicing piece 140 is used to seal the gap between the first panel 110 and the second panel 120. The first temperature sensor 150 is located below the second panel 120 and is used to collect the temperature of the second panel 120. The second temperature sensor 160 is located below the first panel 110 and / or the second panel 120 and is used to collect the temperature of the first panel 110 and / or the second panel 120. The distance between the first temperature sensor 150 and the side of the second panel 120 is L1, and the distance between the second temperature sensor 160 and the side of the second panel 120 is L2, L1>L2; wherein, the operating power of the heating element 130 is associated with the temperature of the first panel 110 and the temperature of the second panel 120.

[0072] When the second panel 120 is installed in the installation hole 111, the first panel 110 and the second panel 120 are combined to form a spliced ​​panel. The second panel 120 is located near the middle of the spliced ​​panel. When the cooking device is used, the cooking utensil 170 needs to be placed in the middle of the spliced ​​panel. Therefore, when the cooking utensil 170 is placed in the correct position, the cooking utensil 170 is mainly supported by the second panel 120. The splicing piece 140 is provided at the splicing position of the first panel 110 and the second panel 120, so that the splicing piece 140 connects the first panel 110 and the second panel 120 at the same time. In one possible application, the splicing piece 140 can seal the gap between the first panel 110 and the second panel 120, thereby achieving a waterproof function.

[0073] The heating element 130 needs to heat the cooking utensil 170. Since the cooking utensil 170 needs to be placed on the second panel 120, at least a portion of the heating element 130 needs to be positioned below the second panel 120 so that the heating element 130 can stably heat the cooking utensil 170. For example, the entire heating element 130 can be installed below the second panel 120, or a portion of the heating element 130 can be positioned below the first panel 110 and another portion of the heating element 130 can be positioned below the second panel 120.

[0074] The first temperature sensor 150 is disposed below the second panel 120, allowing the second temperature sensor 160 to collect the temperature of the second panel 120. The first temperature sensor 150 is spaced relatively large from the side of the second panel 120, while the second temperature sensor 160 is spaced relatively small from the side of the second panel 120. Therefore, the second temperature sensor 160 is positioned near the edge of the second panel 120, enabling it to detect the temperature near the junction of the first and second panels 110 and 120. The first temperature sensor 150 can be mounted near the center of the second panel 120.

[0075] During the heating process of the cooking utensil 170, the temperature of the cooking utensil 170 is relatively high. If the cooking utensil 170 is misaligned, a portion of the cooking utensil 170 may come close to the assembling piece 140, causing the assembling piece 140 to melt. The misalignment of the cooking utensil 170 can be determined based on the temperature change values ​​collected by the first temperature sensor 150 and the second temperature sensor 160, and the operating power of the heating element 130 can be adjusted accordingly.

[0076] For example, during heating of the cooking utensil 170, if the cooking utensil 170 is not misaligned or is slightly misaligned, the first temperature sensor 150 will register a higher temperature value due to its proximity to the center of the second panel 120, while the second temperature sensor 160 will register a lower temperature value due to its proximity to the cooking utensil 170. If the cooking utensil 170 is misaligned, the second temperature sensor 160 will register a relatively higher temperature value, while the first temperature sensor 150 will register a relatively lower temperature value. Therefore, based on the temperature changes registered by the first and second temperature sensors 150, it is possible to determine whether the cooking utensil 170 is misaligned. If the cooking utensil 170 is correctly positioned or slightly misaligned, the operating power of the heating element 130 does not need to be changed. However, if the cooking utensil 170 is misaligned, the operating power of the heating element 130 will need to be reduced or stopped to prevent the cooking utensil 170 from melting the splicing element 140.

[0077] Through the above method, the offset of the cooking utensil 170 can be detected quickly and accurately, and the problem of insufficient temperature resistance of the splicing panel caused by the offset of the cooking utensil 170, which leads to the melting of the splicing piece 140, is solved. The risk of water entering the cooking equipment is reduced, and the electrical components inside the cooking equipment are not easily damaged by moisture, and the risk of short circuit can also be avoided. This not only reduces the damage rate of the cooking equipment, but also reduces the safety risks of users when using the cooking equipment.

[0078] In the embodiment of the present invention, at least one second temperature sensor 160 is added around the defined area of ​​the heating region of the splicing panel, so that the second temperature sensor can effectively detect the temperature of the bottom boundary of the cooking utensil 170 .

[0079] For example, first panel 110 is made of tempered glass, and second panel 120 is made of glass-ceramic. Of course, first panel 110 and second panel 120 can also be made of other materials to quickly transmit the temperature of cooking utensil 170 through the glass. The surface of the panel is not limited to being flat and can be concave or have other shapes.

[0080] In one possible application, the cooking device also includes a base, the first panel 110 is arranged on the base, and the heating element 130, the first temperature sensor 150 and the second temperature sensor 160 are also installed on the base. The heating element 130 can be an electromagnetic heating component, which will not be described here.

[0081] like Figure 4 As shown, in some embodiments, optionally, the position of the second temperature sensor 160 is opposite to the position where the first panel 110 and the second panel 120 are attached.

[0082] When the cooking utensil 170 is placed in the middle of the second panel 120, or is slightly offset from the middle of the second panel 120, the cooking utensil 170 is in the correct position. If the cooking utensil 170 is close to the junction of the first panel 110 and the second panel 120, it indicates that the cooking utensil 170 is not correctly placed, that is, the cooking utensil 170 is offset.

[0083] The second temperature sensor 160 is installed at a position corresponding to the splicing position of the first panel 110 and the second panel 120, so that the second temperature sensor 160 can detect the temperature at the splicing position of the first panel 110 and the second panel 120. If the cooking utensil 170 is placed in an offset position, the temperature at the splicing position of the first panel 110 and the second panel 120 will rise rapidly. Therefore, the above-mentioned installation position of the second temperature sensor 160 can improve the accurate detection of whether the cooking utensil 170 is offset.

[0084] Of course, in other embodiments, the second temperature sensor 160 can also be positioned below the second panel 120 or below the first panel 110. However, if the second temperature sensor 160 is positioned only below the second panel 120, the proximity of the second temperature sensor 160 to the cooking utensil 170 will result in a higher temperature value being recorded by the second temperature sensor 160, even if the cooking utensil 170 is not misplaced. This may reduce the accuracy of detecting misplacement of the cooking utensil 170. If the second temperature sensor 160 is positioned only below the first panel 110, the proximity of the second temperature sensor 160 to the cooking utensil 170 will result in a smaller change in the temperature value recorded by the second temperature sensor 160, even if the cooking utensil 170 is misplaced. This also makes it difficult to improve detection accuracy. Therefore, positioning the second temperature sensor 160 at the junction of the first and second panels 110, 120 can more accurately detect whether the cooking utensil 170 is misplaced.

[0085] Combine Figure 3 and Figure 4 As shown, in some embodiments, optionally, the second temperature sensor 160 includes a plurality of temperature measuring probes 161 , which are used to collect the temperature of the first panel 110 and / or the second panel 120 , and the plurality of temperature measuring probes 161 are distributed at intervals along the circumference of the second panel 120 .

[0086] When the cooking utensil 170 is placed, it may shift in any direction. If multiple temperature measuring probes 161 are provided around the circumference of the second panel 120, any shift in the cooking utensil 170 will result in a significant temperature change being detected by a corresponding temperature measuring probe 161, thereby determining that the cooking utensil 170 has shifted. By increasing the number of temperature measuring probes 161 used, the accuracy of detecting whether the cooking utensil 170 has shifted can be improved.

[0087] The second temperature sensor 160 needs to meet the requirement of adding at least one temperature measuring probe 161, and the number of temperature measuring probes 161 is at least 3, to ensure that no matter how the cooking utensil 170 is offset, it can be effectively detected. At least 3 temperature measuring probes 161 evenly divide the angle a=360 / b, where b is the number of temperature measuring probes 161.

[0088] The temperature measuring probe 161 can be an ordinary thermistor, and the protection point is adjusted based on the temperature difference. For example, in normal thermistor temperature measurement, the protection point needs to be at least 50° C. lower than the material temperature resistance design protection point.

[0089] like Figure 4As shown, in some embodiments, optionally, the second temperature sensor 160 has a first side portion 162 and a second side portion 163, the first side portion 162 and the second side portion 163 are arranged opposite to each other, the distance between the first side portion 162 and the side portion of the second panel 120 is L3, the distance between the second side portion 163 and the side portion of the second panel 120 is L4, and the difference between L3 and L4 is set to L5, L5≤40mm.

[0090] The installation position of the second temperature sensor 160 corresponds to the position where the first panel 110 and the second panel 120 are spliced. The center line of the second temperature sensor 160 can be directly opposite the side of the second panel 120, or the center line of the second temperature sensor 160 can be offset to a certain extent compared to the side of the second panel 120.

[0091] The second temperature sensor 160 has two opposing sides, namely a first side portion 162 and a second side portion 163. When the centerline of the second temperature sensor 160 is aligned with the side of the second panel 120, the first side portion 162 and the second side portion 163 are spaced equal distances from the side of the second panel 120, namely, L3 and L4. If the centerline of the second temperature sensor 160 is offset relative to the side of the second panel 120, L3 may be greater than L4 or less than L4. To prevent the second temperature sensor 160 from being excessively offset, the installation range of the second temperature sensor 160 must be limited.

[0092] The maximum offset distance of the first side portion 162 or the second side portion 163 compared to the side portion of the second panel 120 is 20 mm. In this case, the maximum difference between L3 and L4 is 40 mm. In this case, excessive offset of the second temperature sensor 160 can be avoided, ensuring that the temperature value collected by the second temperature sensor 160 can be used to accurately detect whether the cooking utensil 170 is offset.

[0093] The position of the second temperature sensor 160 between the splicing pieces 140 needs to be within ±20 mm to ensure the accuracy of temperature measurement.

[0094] For example, in embodiments of the present invention, any cooking device using a glass panel can use the temperature measurement method described in the above embodiment to detect pot misalignment. For example, the cooking device can be an induction cooker or a warming plate. The temperature probe 161 is applicable to various types of induction cooker glass panels, thereby improving the safety and stability of the induction cooker.

[0095] In some embodiments, optionally, the first temperature sensor 150 includes an infrared temperature sensor; and / or the second temperature sensor 160 includes an infrared temperature sensor.

[0096] For example, the first temperature sensor 150 and the second temperature sensor 160 may be infrared temperature sensors. In other embodiments, the first temperature sensor 150 and the second temperature sensor 160 may also be thermistor temperature sensors.

[0097] The first temperature sensor 150 and the second temperature sensor 160 can be non-contact infrared temperature sensors, which can measure the temperature of the surface of the cooking utensil without contacting the surface of the cooking utensil, avoiding the problem that conventional thermistors cannot effectively and accurately test the temperature of the bottom of the cooking utensil.

[0098] like Figure 5 As shown, in an embodiment of the present invention, a control method for a cooking device is proposed, which is used for the cooking device in the above embodiment. The control method for the cooking device includes:

[0099] Step 202: Acquire a first temperature change value acquired by a first temperature sensor and a second temperature change value acquired by a second temperature sensor;

[0100] Step 204: Control the operation of the heating element according to the first temperature change value and the second temperature change value.

[0101] The first temperature sensor is positioned below the second panel so that the second temperature sensor can detect the temperature of the second panel. The first temperature sensor is spaced farther apart from the side of the second panel than the second temperature sensor. Therefore, the second temperature sensor is positioned closer to the edge of the second panel, enabling it to detect the temperature near the junction of the first and second panels. The first temperature sensor can be positioned closer to the center of the second panel.

[0102] During the heating process, the temperature of the cooking appliance is high. If the cooking appliance is misaligned, parts of the cooking appliance may come into contact with the splicing parts, causing the splicing parts to melt. The misalignment of the cooking appliance can be determined based on the temperature change values ​​detected by the first temperature sensor and the second temperature sensor, and the operating power of the heating element can be adjusted accordingly.

[0103] For example, during the heating process of a cooking utensil, if the cooking utensil is not misplaced or is slightly misplaced, the first temperature sensor will register a higher temperature value because it is close to the center of the second panel, while the second temperature sensor will register a lower temperature value because it is not close to the cooking utensil. If the cooking utensil is misplaced, the second temperature sensor will register a relatively higher temperature value, while the first temperature sensor will register a relatively lower temperature value. Therefore, based on the temperature change values ​​registered by the first and second temperature sensors, it can be determined whether the cooking utensil is misplaced. When the cooking utensil is accurately placed or slightly misplaced, there is no need to change the operating power of the heating element. However, if the cooking utensil is misplaced, the operating power of the heating element will need to be reduced or stopped to prevent the cooking utensil from melting the spliced ​​components.

[0104] The above method can quickly and accurately detect the deviation of cooking utensils, solve the problem of insufficient temperature resistance of splicing panels and melting of splicing parts caused by the deviation of cooking utensils, and reduce the risk of water intrusion into cooking equipment.

[0105] In some embodiments, optionally, obtaining a first temperature change value collected by the first temperature sensor and a second temperature change value collected by the second temperature sensor includes: when the heating element is running, obtaining the first temperature value collected by the first temperature sensor and the second temperature value collected by the second temperature sensor; when the time after collecting the first temperature value and the second temperature value reaches a set time, obtaining a third temperature value collected by the first temperature sensor and a fourth temperature value collected by the second temperature sensor, the difference between the third temperature value and the first temperature value is the first temperature change value, and the difference between the fourth temperature value and the second temperature value is the second temperature change value.

[0106] During the cooking process, a processor in the cooking device first obtains a first temperature value collected by a first temperature sensor and a second temperature value collected by a second temperature sensor. After a period of heating, the temperature values ​​collected by the first and second temperature sensors change, at which point a third temperature value collected by the first and fourth temperature sensors is obtained. If only the first or second temperature sensor is used to collect temperature change values, even if the cooking appliance is not misaligned, the temperature value collected by the first or second temperature sensor may be abnormal due to other factors. Therefore, combining the temperature change values ​​collected by the first and second temperature sensors can accurately determine whether the cooking appliance is misaligned, thereby improving detection accuracy and reducing the risk of false positives.

[0107] In some embodiments, optionally, the operation of the heating element is controlled according to the first temperature change value and the second temperature change value, including: when the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, maintaining the operating power of the heating element unchanged, and the first set value is greater than or equal to the second set value; when the first temperature change value is greater than the first set value and the second temperature change value is greater than or equal to the second set value, controlling the operating power of the heating element according to the cooking mode of the cooking equipment.

[0108] During the heating process of the cooking utensil, if the placement position of the cooking utensil is not shifted or is slightly shifted, since the cooking utensil is close to the middle of the second panel, the temperature change collected by the first temperature sensor will be relatively large, and since the second temperature sensor is far away from the middle of the second panel, the temperature change collected by the second temperature sensor will be relatively small.

[0109] When obtaining the first temperature change value and the second temperature change value, if the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, the temperature change in the middle of the second panel is larger, and the temperature change in the edge area of ​​the second panel is smaller, which is consistent with the situation where the cooking utensil is placed accurately. Therefore, it is determined that the current cooking utensil has not been significantly displaced. At this time, the operating power of the heating element needs to be changed, and the current operating power can be maintained to continue heating the cooking utensil.

[0110] If the first temperature change value is greater than the first set value, and the second temperature change value is greater than or equal to the second set value, the temperature value change collected by the second temperature sensor is large, which means that the cooking utensil has been displaced. In this case, the adjustment method of the operating power of the heating element is determined based on the collected temperature change value and the cooking mode of the cooking equipment. By making targeted adjustments to the operating power of the heating element, stable heating of the cooking utensil can be guaranteed as much as possible, and the problem of melting of the spliced ​​parts can be avoided.

[0111] Exemplarily, the first set value is 10°C, and the second set value is 10°C.

[0112] In some embodiments, optionally, according to the cooking mode of the cooking equipment, the operating power of the heating element is controlled, including: when the cooking mode is a first mode, adjusting the operating power of the heating element, wherein the operating power of the heating element is inversely proportional to the temperature value collected by the second temperature sensor; when the cooking mode is a second mode, controlling the heating element to stop operating; wherein the first mode includes any one of the following: steaming mode, soup mode, hot pot mode; the second mode includes any one of the following: stir-frying mode, frying mode, and grilling mode.

[0113] If the cooking appliance is misaligned, the heating element needs to be controlled according to the cooking mode of the cooking device. In cooking modes such as steaming, soup making, or hot pot, water is primarily used as the heating medium. When there is water in the cooking appliance, the temperature of the cooking appliance will not be too high. In this case, even if the cooking appliance is misaligned, it is unlikely to cause the joints to melt. In this case, the heating element can be controlled to continue cooking at the current operating power or reduced in power, thereby ensuring stable heating of the cooking appliance.

[0114] When there is water in the cooking container, the temperature of the cooking container is unlikely to continue to rise after reaching a certain value. If the water in the cooking container boils away, the temperature of the cooking container will rise rapidly. Therefore, in the first cooking mode, when the second temperature change value is greater than the second set value, as the temperature value collected by the second temperature sensor increases, the operating power of the heating element needs to be reduced accordingly to prevent damage to the cooking appliance due to dry cooking.

[0115] In cooking modes such as stir-fry mode, frying mode or grilling mode, the cooking appliance does not need water as a heating medium. The cooking appliance directly heats the food. As the cooking appliance is heated, the temperature of the cooking appliance will reach a higher temperature. If the cooking appliance is misaligned at this time, the cooking appliance may easily cause heat melting of the splicing parts. Therefore, in the second mode, if the cooking appliance is misaligned, the heating element is controlled to stop running, thereby stopping heating the cooking appliance.

[0116] In some embodiments, optionally, in some embodiments, optionally, according to the cooking mode of the cooking device, the operating power of the heating element is controlled, including: when the cooking mode is the first mode and the temperature collected by the first temperature sensor is less than or equal to the fifth set value, adjusting the operating power of the heating element, wherein the operating power of the heating element is inversely proportional to the temperature value collected by the second temperature sensor; when the cooking mode is the second mode, controlling the heating element to stop operating; wherein the first mode includes any one of the following: steaming mode, soup mode, hot pot mode; the second mode includes any one of the following: stir-frying mode, frying mode, frying mode.

[0117] In cooking modes such as steaming mode, soup mode, or hot pot mode, it is also necessary to determine whether the temperature currently recorded by the first temperature sensor reaches a fifth set value. If the temperature reaches the fifth set value, it indicates that the temperature of the cooking appliance is too high, and the water in the cooking appliance may have boiled dry. Therefore, in the first mode, if the temperature value recorded by the first temperature sensor is less than or equal to the fifth set value, the heating element may continue to operate. In the first mode, if the temperature value recorded by the first temperature sensor is greater than the fifth set value, the heating element is controlled to stop operating.

[0118] Exemplarily, the fifth set value is 120°C.

[0119] In some embodiments, optionally, controlling the operating power of the heating element according to the cooking mode of the cooking equipment also includes: in the case of the first mode, controlling the heating element to stop operating based on the second temperature change value being greater than or equal to a third set value, and the third set value being greater than the second set value.

[0120] When the cooking device is operating in the first mode, the temperature value recorded by the second temperature sensor increases, and the operating power of the heating element decreases accordingly. However, when the second temperature change value is greater than or equal to the third set value, it indicates that the temperature value recorded by the second temperature sensor has reached a high value. If the cooking device continues to heat at this time, the cooking device may cause the joint to melt. Therefore, it is necessary to control the heating element to stop operating to ensure the seal between the first panel and the second panel.

[0121] Exemplarily, the third set value is 50°C.

[0122] In some embodiments, optionally, when the second temperature change value is obtained, the control method further includes: controlling the heating element to stop operating when the temperature value collected by the first temperature sensor is greater than a fourth set value.

[0123] During the cooking process, it is necessary to judge whether the temperature value collected by the first temperature sensor reaches the fourth set value. If the temperature collected by the first temperature sensor reaches the fourth set value, it means that the current cooking appliance has reached a higher temperature. The fourth set value can be the limit temperature value set inside the cooking device. When this temperature value is reached, it means that the temperature of the cooking appliance is abnormal. At this time, it is necessary to control the heating element to stop running to ensure the safety of the cooking device during use.

[0124] Exemplarily, the fourth set value is 260°C.

[0125] In some embodiments, optionally, controlling the operation of the heating element according to the first temperature change value and the second temperature change value also includes: controlling the heating element to stop operating when the first temperature change value is less than the first set value and the second temperature change value is greater than the second set value.

[0126] If the temperature change value detected by the first temperature sensor is less than the first set value, and the temperature change value detected by the second temperature sensor is greater than the second set value, it means that the cooking utensil is not heated normally. At this time, it can be determined that the cooking utensil is misaligned and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor. Heating needs to be stopped immediately to ensure the safety of the cooking equipment.

[0127] In some embodiments, optionally, when the first temperature change value is less than the first set value, and the second temperature change value is greater than the second set value, the control method further includes: outputting a reminder message.

[0128] When it is determined that the cooking utensil is misaligned and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor, the cooking device outputs a reminder message to remind the user to deal with the problem of the current misalignment of the cooking utensil.

[0129] For example, the reminder information may be sound information or optical information.

[0130] In an embodiment of the present invention, when a cooking utensil is placed on a cooking device for heating, three temperature probes are used for exemplary purposes, arranged evenly at a 120-degree angle. The processor first obtains the initial temperatures of the three temperature probes and stores them as T1, T2, and T3, along with the first temperature sensor T0. After heating for a period of time t (at least 30 seconds), the temperature changes. The temperature of the temperature probes is then compared with the temperature of the first temperature sensor, i.e., t1, t2, t3, and t0, resulting in the following three conditions.

[0131] State 1: The cooking appliance is not deflected at all.

[0132] Detect the temperature t0 of the first temperature sensor. If the temperature t0 changes normally with the increase of power, and the current temperature probe temperatures t1, t2, t3 differ from the initial infrared temperature measurement temperatures T1, T2, T3 by less than 10°C, and the difference in t0 is large (greater than 50°C), then it is determined that the cooking appliance has not been incorrectly offset, and the current cooking mode is maintained.

[0133] State 2: The cooking utensil is offset or the bottom diameter of the cooking utensil exceeds the range of the joint piece, but does not deviate from the position detectable by the first temperature sensor.

[0134] If the temperature probe detects a temperature change, and if the current t1, t2, t3 is detected to differ from the initial infrared temperature T1, T2, T3 by more than 10°C, and t0 increases normally, then it is determined that the cooking appliance has shifted a certain amount. The program identification function is steaming, hot pot, and soup making. This type of function is mainly designed for water at 100°C. The user will not be prompted to deviate from the pot, and t0 will continue to control the cooking function. Only when the temperature difference of any temperature probe t1, t2, t3 exceeds 100°C, the power reduction control will be actively performed. When the temperature change increases by 10°C, the program will reduce the power by at least 500W.

[0135] The specific power control is Pt = P-(△t-10)×500, where △t is the maximum temperature difference between the three temperature measuring probes, Pt is the target operating power of the heating element, or the operating power that currently needs to be adjusted to, and P is the power between power reduction operations. For example, P is the operating power of the heating element when the cooking equipment is just started.

[0136] For example, for a 2000W product, when the temperature difference exceeds 20°C, the power needs to be reduced to 1500W; when the temperature difference exceeds 30°C, the power needs to be reduced to 1000W; when the temperature difference exceeds 40°C, the power needs to be reduced to 500W; and when the temperature difference exceeds 50°C, the power needs to be reduced to 0.

[0137] When the program identifies high-temperature power, such as stir-frying or frying, it will directly prompt that the cooking utensil is offset, and an alarm will be given to stop heating at the same time.

[0138] State three: the cooking utensil is offset and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor.

[0139] Detect the temperature t0 of the first temperature sensor. If t0 does not change and the current temperature probe temperatures t1, t2, t3 differ from the initial T1, T2, T3 by more than 10°C, an alarm will be issued to remind the user that the device cannot be used.

[0140] like Figure 6 As shown, in a possible embodiment, the control method of the cooking device includes:

[0141] Step 302, infrared temperature measurement call;

[0142] Step 304 , initializing the cache, obtaining the temperatures of the three temperature measuring probes and the temperatures T1 , T2 , T3 , and T0 of the first temperature sensor;

[0143] Step 306: After heating t, collect t0, t1, t2, and t3;

[0144] Step 308, T1-t1≥10°C, or T2-t2≥10°C, or T3-t3≥10°C, if yes, go to step 310, otherwise go to step 312;

[0145] Step 310, |t0-T0|<10°C, if yes, go to step 314, if no, go to step 316;

[0146] Step 312, t0>260°C, if yes, go to step 322, if no, go to step 324;

[0147] Step 314: Display a fault code to inform the consumer that the device cannot be used.

[0148] Step 316, the cooking function is low-temperature water function, t0≤120°C, if so, go to step 318, if not, go to step 322;

[0149] Step 318, Pt = P - (Δt - 10) × 500;

[0150] Step 320: T1-t1≥50°C, or T2-t2≥50°C, or T3-t3≥50°C. If yes, go to step 322; otherwise, go back to step 312.

[0151] Step 322, P0=0W;

[0152] Step 324: Maintain the current functional cooking state and continue heating.

[0153] like Figure 7 As shown, in an embodiment of the present invention, a control device 400 for a cooking device is provided, which is used for a cooking device as in any of the above embodiments. The control device 400 for the cooking device includes:

[0154] An acquisition module 410 is configured to acquire a first temperature change value acquired by a first temperature sensor and a second temperature change value acquired by a second temperature sensor;

[0155] The control module 420 is configured to control the operation of the heating element according to the first temperature change value and the second temperature change value.

[0156] The first temperature sensor is positioned below the second panel so that the second temperature sensor can detect the temperature of the second panel. The first temperature sensor is spaced farther apart from the side of the second panel than the second temperature sensor. Therefore, the second temperature sensor is positioned closer to the edge of the second panel, enabling it to detect the temperature near the junction of the first and second panels. The first temperature sensor can be positioned closer to the center of the second panel.

[0157] During the heating process, the temperature of the cooking appliance is high. If the cooking appliance is misaligned, parts of the cooking appliance may come into contact with the splicing parts, causing the splicing parts to melt. The misalignment of the cooking appliance can be determined based on the temperature change values ​​detected by the first temperature sensor and the second temperature sensor, and the operating power of the heating element can be adjusted accordingly.

[0158] For example, during the heating process of a cooking utensil, if the cooking utensil is not misplaced or is slightly misplaced, the first temperature sensor will register a higher temperature value because it is close to the center of the second panel, while the second temperature sensor will register a lower temperature value because it is not close to the cooking utensil. If the cooking utensil is misplaced, the second temperature sensor will register a relatively higher temperature value, while the first temperature sensor will register a relatively lower temperature value. Therefore, based on the temperature change values ​​registered by the first and second temperature sensors, it can be determined whether the cooking utensil is misplaced. When the cooking utensil is accurately placed or slightly misplaced, there is no need to change the operating power of the heating element. However, if the cooking utensil is misplaced, the operating power of the heating element will need to be reduced or stopped to prevent the cooking utensil from melting the spliced ​​components.

[0159] The above method can quickly and accurately detect the deviation of cooking utensils, solve the problem of insufficient temperature resistance of splicing panels and melting of splicing parts caused by the deviation of cooking utensils, and reduce the risk of water intrusion into cooking equipment.

[0160] In some embodiments, optionally, the acquisition module is specifically used to: when the heating element is running, obtain a first temperature value collected by the first temperature sensor and a second temperature value collected by the second temperature sensor; when the time after collecting the first temperature value and the second temperature value reaches a set time, obtain a third temperature value collected by the first temperature sensor and a fourth temperature value collected by the second temperature sensor, the difference between the third temperature value and the first temperature value is a first temperature change value, and the difference between the fourth temperature value and the second temperature value is a second temperature change value.

[0161] During the cooking process, a processor in the cooking device first obtains a first temperature value collected by a first temperature sensor and a second temperature value collected by a second temperature sensor. After a period of heating, the temperature values ​​collected by the first and second temperature sensors change, at which point a third temperature value collected by the first and fourth temperature sensors is obtained. If only the first or second temperature sensor is used to collect temperature change values, even if the cooking appliance is not misaligned, the temperature value collected by the first or second temperature sensor may be abnormal due to other factors. Therefore, combining the temperature change values ​​collected by the first and second temperature sensors can accurately determine whether the cooking appliance is misaligned, thereby improving detection accuracy and reducing the risk of false positives.

[0162] In some embodiments, optionally, the control module is specifically used to: maintain the operating power of the heating element unchanged when the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, and the first set value is greater than or equal to the second set value; control the operating power of the heating element according to the cooking mode of the cooking equipment when the first temperature change value is greater than the first set value and the second temperature change value is greater than or equal to the second set value.

[0163] During the heating process of the cooking utensil, if the placement position of the cooking utensil is not shifted or is slightly shifted, since the cooking utensil is close to the middle of the second panel, the temperature change collected by the first temperature sensor will be relatively large, and since the second temperature sensor is far away from the middle of the second panel, the temperature change collected by the second temperature sensor will be relatively small.

[0164] When obtaining the first temperature change value and the second temperature change value, if the first temperature change value is greater than the first set value and the second temperature change value is less than the second set value, the temperature change in the middle of the second panel is larger, and the temperature change in the edge area of ​​the second panel is smaller, which is consistent with the situation where the cooking utensil is placed accurately. Therefore, it is determined that the current cooking utensil has not been significantly displaced. At this time, the operating power of the heating element needs to be changed, and the current operating power can be maintained to continue heating the cooking utensil.

[0165] If the first temperature change value is greater than the first set value, and the second temperature change value is greater than or equal to the second set value, the temperature value change collected by the second temperature sensor is large, which means that the cooking utensil has been displaced. In this case, the adjustment method of the operating power of the heating element is determined based on the collected temperature change value and the cooking mode of the cooking equipment. By making targeted adjustments to the operating power of the heating element, stable heating of the cooking utensil can be guaranteed as much as possible, and the problem of melting of the spliced ​​parts can be avoided.

[0166] Exemplarily, the first set value is 10°C, and the second set value is 10°C.

[0167] In some embodiments, optionally, the control module is also used to: when the cooking mode is the first mode, adjust the operating power of the heating element, wherein the operating power of the heating element is inversely proportional to the temperature value collected by the second temperature sensor; when the cooking mode is the second mode, control the heating element to stop operating; wherein the first mode includes any one of the following: steaming mode, soup mode, hot pot mode; the second mode includes any one of the following: stir-frying mode, frying mode, and grilling mode.

[0168] If the cooking appliance is misaligned, the heating element needs to be controlled according to the cooking mode of the cooking device. In cooking modes such as steaming, soup making, or hot pot, water is primarily used as the heating medium. When there is water in the cooking appliance, the temperature of the cooking appliance will not be too high. In this case, even if the cooking appliance is misaligned, it is unlikely to cause the joints to melt. In this case, the heating element can be controlled to continue cooking at the current operating power or reduced in power, thereby ensuring stable heating of the cooking appliance.

[0169] When there is water in the cooking container, the temperature of the cooking container is unlikely to continue to rise after reaching a certain value. If the water in the cooking container boils away, the temperature of the cooking container will rise rapidly. Therefore, in the first cooking mode, when the second temperature change value is greater than the second set value, as the temperature value collected by the second temperature sensor increases, the operating power of the heating element needs to be reduced accordingly to prevent damage to the cooking appliance due to dry cooking.

[0170] In cooking modes such as stir-fry mode, frying mode or grilling mode, the cooking appliance does not need water as a heating medium. The cooking appliance directly heats the food. As the cooking appliance is heated, the temperature of the cooking appliance will reach a higher temperature. If the cooking appliance is misaligned at this time, the cooking appliance may easily cause heat melting of the splicing parts. Therefore, in the second mode, if the cooking appliance is misaligned, the heating element is controlled to stop running, thereby stopping heating the cooking appliance.

[0171] In some embodiments, optionally, in some embodiments, optionally, the control module is also used to: when the cooking mode is the first mode and the temperature collected by the first temperature sensor is less than or equal to the fifth set value, adjust the operating power of the heating element, wherein the operating power of the heating element is inversely proportional to the temperature value collected by the second temperature sensor; when the cooking mode is the second mode, control the heating element to stop operating; wherein the first mode includes any one of the following: steaming mode, soup mode, hot pot mode; the second mode includes any one of the following: stir-frying mode, frying mode, frying mode.

[0172] In cooking modes such as steaming mode, soup mode, or hot pot mode, it is also necessary to determine whether the temperature currently recorded by the first temperature sensor reaches a fifth set value. If the temperature reaches the fifth set value, it indicates that the temperature of the cooking appliance is too high, and the water in the cooking appliance may have boiled dry. Therefore, in the first mode, if the temperature value recorded by the first temperature sensor is less than or equal to the fifth set value, the heating element may continue to operate. In the first mode, if the temperature value recorded by the first temperature sensor is greater than the fifth set value, the heating element is controlled to stop operating.

[0173] In some embodiments, optionally, the control module is further configured to: in the first mode, control the heating element to stop operating based on the second temperature change value being greater than or equal to a third set value, and the third set value being greater than the second set value.

[0174] When the cooking device is operating in the first mode, the temperature value recorded by the second temperature sensor increases, and the operating power of the heating element decreases accordingly. However, when the second temperature change value is greater than or equal to the third set value, it indicates that the temperature value recorded by the second temperature sensor has reached a high value. If the cooking device continues to heat at this time, the cooking device may cause the joint to melt. Therefore, it is necessary to control the heating element to stop operating to ensure the seal between the first panel and the second panel.

[0175] Exemplarily, the third set value is 50°C.

[0176] In some embodiments, optionally, when the second temperature change value is obtained, the control module is further configured to: control the heating element to stop operating when the temperature value collected by the first temperature sensor is greater than a fourth set value.

[0177] During the cooking process, it is necessary to judge whether the temperature value collected by the first temperature sensor reaches the fourth set value. If the temperature collected by the first temperature sensor reaches the fourth set value, it means that the current cooking appliance has reached a higher temperature. The fourth set value can be the limit temperature value set inside the cooking device. When this temperature value is reached, it means that the temperature of the cooking appliance is abnormal. At this time, it is necessary to control the heating element to stop running to ensure the safety of the cooking device during use.

[0178] Exemplarily, the fourth set value is 260°C.

[0179] In some embodiments, optionally, the control module is further configured to: control the heating element to stop operating when the first temperature change value is less than a first set value and the second temperature change value is greater than a second set value.

[0180] If the temperature change value detected by the first temperature sensor is less than the first set value, and the temperature change value detected by the second temperature sensor is greater than the second set value, it means that the cooking utensil is not heated normally. At this time, it can be determined that the cooking utensil is misaligned and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor. Heating needs to be stopped immediately to ensure the safety of the cooking equipment.

[0181] In some embodiments, optionally, when the first temperature change value is less than the first set value, and the second temperature change value is greater than the second set value, the control module is further configured to: output a reminder message.

[0182] When it is determined that the cooking utensil is misaligned and the bottom of the cooking utensil is completely out of the detection range of the first temperature sensor, the cooking device outputs a reminder message to remind the user to deal with the problem of the current misalignment of the cooking utensil.
