[0052] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0053] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0054] Example 1

[0055] This embodiment provides a method for detecting pot slippage, applied to a range hood and cooktop linkage device. The range hood and cooktop linkage device includes a cooktop, such as... Figure 1 As shown, the method for detecting a slippery pan includes:

[0056] S1. Obtain the current reflected light intensity value corresponding to the pot on the stove.

[0057] S2. Determine whether the cookware is slipping based on the preset light intensity value and the current reflected light intensity value.

[0058] When a cookware slips, the current reflected light intensity value of the cookware will change. Therefore, the slippage can be detected by the reflected light intensity value.

[0059] The current reflected light intensity value of the cookware can be collected by a light intensity detection component installed on the cookware.

[0060] The disclosed method for detecting pot slippage obtains the current reflected light intensity value of the pot on the stove and determines whether the pot has slipped based on the preset light intensity value and the current reflected light intensity value. This method is simple and reliable, improves the accuracy of pot slippage detection, and ensures user safety.

[0061] In an alternative implementation, such as Figure 2 As shown, the steps following step S1 include:

[0062] S3. Obtain the reference reflected light intensity value corresponding to the cookware.

[0063] S4. Calculate the absolute value of the difference between the current reflected light intensity value and the reference reflected light intensity value.

[0064] Step S2 above includes:

[0065] S21. Determine whether the cookware is slipping based on the absolute value and the preset light intensity value.

[0066] The baseline reflected light intensity value corresponds to the reflected light intensity value of the cookware when it does not slip, and can be determined through experimental values ​​or actual measurements. For example, when a user uses the cookware for the first time, the cookware is numbered, and a light intensity value test mode is entered, reminding the user to place the cookware stably, thereby measuring and storing the corresponding baseline reflected light intensity value for the cookware for subsequent use.

[0067] In this embodiment, the difference between the current reflected light intensity value and the reference reflected light intensity value is calculated, and the absolute value of the light intensity difference is compared with the preset light intensity value to determine whether the cookware has slipped.

[0068] The reference reflected light intensity value of the cookware can be collected by a light intensity detection component installed on the cookware.

[0069] In an alternative implementation, such as Figure 3 As shown, step S21 above includes:

[0070] S211. Obtain the first preset light intensity value and the second preset light intensity value.

[0071] S212. If the absolute value is greater than the second preset light intensity value and less than the first preset light intensity value, then it is determined that the cookware has slipped.

[0072] When the absolute value of the light intensity difference is greater than the second preset light intensity value and less than the first preset light intensity value, it is determined that the cookware has slipped.

[0073] In an alternative implementation, such as Figure 4 As shown, the steps preceding step S1 include:

[0074] S01. Obtain the current value of the solenoid valve corresponding to the stove.

[0075] S02. Determine whether the stove is in the off state based on the current value of the solenoid valve.

[0076] If so, then proceed to step S1, that is, if the stove is in the off state, proceed to the step of obtaining the current reflected light intensity value corresponding to the pot on the stove.

[0077] The stove's status can be determined by the current value of the solenoid valve corresponding to the stove. If the current value is less than the preset current value, the stove is considered to be off; otherwise, it is on. If the stove is off, a pan-slip detection is performed (before or after cooking) to directly obtain the current reflected light intensity value of the pan on the stove before proceeding to the next step.

[0078] In an alternative implementation, such as Figure 5 As shown, if the stove is in the ignition state, steps S03 and S04 are executed sequentially.

[0079] S03. Obtain the current temperature value corresponding to the cookware.

[0080] S04. Determine whether the current temperature value is greater than the first preset temperature threshold.

[0081] If so, then proceed to step S1, that is, if the current temperature value is greater than the first preset temperature threshold, then proceed to obtain the current reflected light intensity value corresponding to the pot on the stove.

[0082] If the stove is on, a pan slip detection is performed while the stove is on (cooking). At this time, the current temperature value of the pan needs to be obtained first, and the current temperature value is compared with the first preset temperature threshold. If the current temperature value is greater than the first preset temperature threshold, the current reflected light intensity value of the pan on the stove is obtained, and the next step is performed.

[0083] In an alternative implementation, such as Figure 6 As shown, if the stove is in the ignition state, steps S03, S05 and S06 are executed sequentially.

[0084] S03. Obtain the current temperature value corresponding to the cookware.

[0085] S05. Obtain the derivative of the current temperature value with time.

[0086] S06. Determine whether the derivative value is greater than the second preset temperature threshold.

[0087] If so, then step S1 is executed, that is, if the derivative value is greater than the second preset temperature threshold, then the step of obtaining the current reflected light intensity value corresponding to the pot on the stove is executed.

[0088] If the stove is on, a pan slip detection is performed. At this time, the current temperature value of the pan needs to be obtained, the derivative of the current temperature value with time is calculated, and the derivative value is compared with the second preset temperature threshold. If the derivative value is greater than the second preset temperature threshold, the current reflected light intensity value of the pan on the stove is obtained, and the next step is performed.

[0089] By comparing the derivative of the current temperature of the cookware with time with a second preset temperature threshold, the change of the current temperature of the cookware over time can be accurately determined, thereby more accurately determining whether the stove is in the on state, and then performing pan slip detection in the on state.

[0090] In an alternative implementation, such as Figure 7 As shown, the method for detecting a slippery pan also includes:

[0091] S5. If it is determined that the pot has slipped, a first adjustment signal is sent to the stove to adjust the stove to turn off the heat.

[0092] If the cookware has already slipped off the stove, turn it off to prevent the cooking liquid from extinguishing the gas flame and causing a gas leak. Therefore, you need to turn off the stove immediately to avoid a continued gas leak.

[0093] The pot slip detection method of this embodiment links the stove and the pot together, and can intelligently realize a series of safety handling operations after the pot slips, providing users with a safe and reliable product.

[0094] In an alternative implementation, such as Figure 8 As shown, the method for detecting a slippery pan also includes:

[0095] S6. If it is determined that the cookware has slipped, a reminder message will be triggered to indicate that the cookware has slipped.

[0096] If the cookware has already slipped, a notification will be sent to the user, which can be a voice announcement or a buzzer. This disclosure does not limit the type of notification message.

[0097] In an optional embodiment, the range hood and cooktop linkage device further includes a range hood, such as... Figure 8 As shown, the method for detecting a slippery pan also includes:

[0098] S7. If it is determined that the cookware has slipped, a second adjustment signal is sent to the range hood to adjust the range hood to the maximum airflow.

[0099] Generally speaking, when a cookware slips, the cooking liquid in the pot will extinguish the open flame of the gas, leading to a gas leak. It is necessary to turn off the stove immediately to prevent the gas leak from continuing. At the same time, turn the range hood to the maximum speed to quickly remove the leaked gas and ensure user safety.

[0100] The pot slip detection method of this embodiment links the stove, pot and range hood, and can intelligently realize a series of safety handling operations after the pot slips, providing users with a safe and reliable product.

[0101] Example 2

[0102] This embodiment provides a stove-range cooker linkage device, which includes a cooker. The stove-range cooker linkage device uses the pot slip detection method in Embodiment 1 to detect pot slippage on the cooker.

[0103] In an optional embodiment, the range hood and stove linkage device also includes a range hood.

[0104] In one alternative embodiment, the cooktop is equipped with a temperature sensor for detecting the current temperature of the cookware.

[0105] The temperature sensor can be placed in the center of the stove burner, in contact with the outer surface of the cookware. Alternatively, the temperature sensor can be placed on the cookware support of the stove, also in contact with the outer surface of the cookware; the placement should be based on the ability to capture the current temperature of the cookware.

[0106] In one alternative embodiment, the cooktop is equipped with a light intensity detection component, which is used to detect the reflected light intensity value of the cooktop.

[0107] The light intensity detection component includes a light source and a light intensity sensor. The light source emits light that shines on the bottom of the cookware, and the light intensity sensor is used to detect the intensity of the light reflected from the cookware.

[0108] The light intensity detection component can be installed outside the cooktop, ensuring it is not obstructed and can detect the reflected light intensity from the bottom of the pot. Alternatively, it can be installed inside the cooktop, again ensuring it is not obstructed and can detect the reflected light intensity from the bottom of the pot. For example, it can be positioned parallel to and close to the burner head.

[0109] like Figure 10 As shown, the temperature sensor is located at the center of the stove head, in contact with the outer surface of the cookware, and the light intensity detection component is located inside the stove, parallel to and close to the stove head.

[0110] The range hood and cooktop linkage device in this embodiment uses the pot slip detection method in Embodiment 1 to determine whether the pot on the cooktop has slipped. This pot slip detection method is simple and reliable, improves the accuracy of pot slip detection, and ensures user safety. At the same time, the range hood and cooktop linkage device links the cooktop and the range hood, and can intelligently realize a series of safety handling operations after the pot slips, providing users with a safe and reliable product.

[0111] Example 3

[0112] This embodiment provides a range hood and cooktop linkage system, which includes cookware and the range hood and cooktop linkage device in Embodiment 2.

[0113] The range hood and cooktop linkage system may also include other components, such as a communication module and a cooktop status acquisition module. The communication module can communicate with the control circuit boards inside the cooktop and the range hood respectively. The cooktop status acquisition module can acquire the status of the cooktop, such as on and off signals, through the communication module, and send the cooktop status to the control circuit board inside the range hood through the communication module to realize the linkage control of the range hood and cooktop.

[0114] The range hood and cooktop linkage system of this embodiment includes a cookware and the range hood and cooktop linkage device of Embodiment 2. By acquiring the current reflected light intensity value corresponding to the cookware on the cooktop, it determines whether the cookware has slipped based on the preset light intensity value and the current reflected light intensity value. This cookware slip detection method is simple and reliable, improves the accuracy of cookware slip detection, and ensures user safety. At the same time, the cookware slip detection method links the cooktop and range hood, which can intelligently realize a series of safety handling operations after the cookware slips, providing users with a safe and reliable product.
