[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. In response to the vibration of the pot on the stove, obtain the actual number of vibrations of the pot.
[0057] S2. Determine whether the cookware slips based on the preset number of vibrations and the actual number of vibrations.
[0058] When a pot on the stove slips, it vibrates. Therefore, the vibration of the pot can be used to detect if the pot is slipping.
[0059] The disclosed method for detecting pot slippage involves responding to the vibration of the pot on the stove, obtaining the actual number of vibrations of the pot, and determining whether the pot has slipped based on the preset number of vibrations and the actual number of vibrations. This method is simple and reliable, improves the accuracy of pot slippage detection, and ensures user safety.
[0060] In an alternative implementation, such as Figure 2 As shown, the steps preceding step S1 include:
[0061] S01. Obtain the vibration data corresponding to the cookware.
[0062] S02. Determine whether the cookware is vibrating based on vibration data.
[0063] Step S1 above includes:
[0064] S11. In response to the vibration of the pot on the stove, obtain the actual number of vibrations of the pot based on the vibration data.
[0065] Vibration data characterizes the vibration of the cookware, and includes, but is not limited to, the number of vibrations. Vibration data also includes amplitude and frequency. Vibration data can be collected from the cookware using vibration sensors installed on the cooktop.
[0066] In an alternative implementation, such as Figure 3 As shown, step S2 above includes:
[0067] S21. If the actual number of vibrations is greater than the preset number of vibrations, it is determined that the pot has slipped.
[0068] The preset number of vibrations can be determined based on empirical or experimental values. For example, the preset number of vibrations could be 3.
[0069] In an alternative implementation, such as Figure 4 As shown, the steps preceding step S01 above include:
[0070] S03. Obtain the current value of the solenoid valve corresponding to the stove.
[0071] S04. Determine whether the stove is in the off state based on the current value of the solenoid valve.
[0072] If so, then execute step S01 above, that is, if the stove is in the off state, then execute the step of obtaining the vibration data corresponding to the pot.
[0073] The stove's status can be determined by the current value of the solenoid valve. If the current value is less than the preset value, the stove is considered off; otherwise, it is on. If the stove is off, a pan-slip detection is performed (before or after cooking) to obtain the corresponding vibration data and proceed to the next step.
[0074] In an alternative implementation, such as Figure 5 As shown, if the stove is in the ignition state, steps S05 and S06 are executed sequentially.
[0075] S05. Obtain the current temperature value corresponding to the cookware.
[0076] S06. Determine whether the current temperature value is greater than the first preset temperature threshold.
[0077] If so, then execute the above step S01, that is, if the current temperature value is greater than the first preset temperature threshold, then execute the step of obtaining the vibration data corresponding to the cookware.
[0078] 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 vibration data of the pan is obtained, and the next step is performed.
[0079] In an alternative implementation, such as Figure 6 As shown, if the stove is in the ignition state, steps S05, S07 and S08 are executed sequentially.
[0080] S05. Obtain the current temperature value corresponding to the cookware.
[0081] S07. Obtain the derivative of the current temperature value with time.
[0082] S08. Determine whether the derivative value is greater than the second preset temperature threshold.
[0083] If so, then execute the above step S01, that is, if the derivative value is greater than the second preset temperature threshold, then execute the step of obtaining the vibration data corresponding to the cookware.
[0084] 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 vibration data of the pan is obtained, and the next step is performed.
[0085] 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.
[0086] In an alternative implementation, such as Figure 7 As shown, the method for detecting a slippery pan also includes:
[0087] S3. 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.
[0088] 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.
[0089] 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.
[0090] In an alternative implementation, such as Figure 8 As shown, the method for detecting a slippery pan also includes:
[0091] S4. If it is determined that the cookware has slipped, a reminder message will be triggered to indicate that the cookware has slipped.
[0092] 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.
[0093] In an optional embodiment, the range hood and cooktop linkage device further includes a range hood, such as... Figure 9 As shown, the method for detecting a slippery pan also includes:
[0094] S5. 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.
[0095] 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.
[0096] 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.
[0097] Example 2
[0098] 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.
[0099] In an optional embodiment, the range hood and stove linkage device also includes a range hood.
[0100] In one alternative embodiment, the cooktop is equipped with a temperature sensor for detecting the current temperature of the cookware.
[0101] 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.
[0102] In an alternative embodiment, the cooktop is equipped with a vibration sensor for detecting vibration data of the cookware.
[0103] The vibration sensor can be placed in the center of the stove burner, in contact with the outer surface of the cookware.
[0104] like Figure 10 As shown, both the vibration sensor and the temperature sensor are located at the center of the stove head, in contact with the outer surface of the cookware.
[0105] 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.
[0106] Example 3
[0107] This embodiment provides a range hood and cooktop linkage system, which includes cookware and the range hood and cooktop linkage device in Embodiment 2.
[0108] 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.
[0109] 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 responding to the vibration of the cookware on the cooktop, the system obtains the actual number of vibrations of the cookware and determines whether the cookware has slipped based on the preset number of vibrations and the actual number of vibrations. The method of detecting slipping by means of cookware vibration is simple and reliable, improves the accuracy of slipping detection, and ensures user safety. At the same time, the slipping detection method links the cooktop and the range hood, which can intelligently realize a series of safety handling operations after the cookware slips, providing users with a safe and reliable product.
