Description

Technical Field

[0001] This invention relates to the field of gas stove technology, specifically to a gas stove control method and a gas stove. Background Technology

[0002] Currently, gas stoves with anti-dry-burning functions typically have a temperature sensor in the center of the burner to detect the temperature of the pot bottom and compare it with a preset temperature value to determine if dry burning has occurred. If dry burning is detected, an alarm is triggered and the flame is shut off. However, when the dry-burning protection is triggered, the food inside the pot is often already burnt or spoiled due to excessive heat, making it inedible and resulting in waste.

[0003] In summary, current technology has a technical problem where, when a gas stove triggers the dry-burn protection, the food being cooked in the pot spoils due to excessively high temperatures, making it inedible and wasting food. Summary of the Invention

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0050] Figure 1 This invention illustrates a first flowchart of a gas stove control method according to an embodiment of the present invention, as shown below. Figure 1 As shown, the gas stove control method provided in this application includes:

[0051] Step S110: After receiving the start command, start the gas stove and obtain the warning temperature threshold and the dry burning protection temperature threshold, wherein the warning temperature threshold is less than the dry burning protection temperature threshold.

[0052] In this embodiment, after receiving the gas stove start command, the gas stove controller starts the gas stove and initializes the warning temperature threshold and the dry burning protection temperature threshold, wherein the warning temperature threshold is less than the dry burning protection temperature threshold.

[0053] Step S120: Obtain the real-time temperature of the cookware on the gas stove.

[0054] In this embodiment, following step S110, after starting the gas stove, the real-time temperature of the cookware on the gas stove is continuously acquired.

[0055] Step S130: Issue an early warning when the real-time temperature reaches the warning temperature threshold.

[0056] In this embodiment, when the real-time temperature of the cookware on the gas stove reaches the warning temperature threshold, a warning is issued to the user.

[0057] In some embodiments, issuing an early warning includes: issuing an early warning through at least one of the following methods: light, sound, text message, and application push notification. Specifically, the early warning method can be one of the following, or any combination of several: light, sound, text message, application push notification, etc.

[0058] In some embodiments, after issuing a warning when the real-time temperature reaches the warning temperature threshold, the method further includes: detecting a firepower adjustment command from a user terminal; and adjusting the firepower in response to the firepower adjustment command.

[0059] Specifically, this embodiment addresses adjusting the heat output via a user terminal. This embodiment assumes that the gas stove is wirelessly connected to the user terminal before startup, and that the gas stove and user terminal can communicate with each other. The user can adjust the gas stove's operation via the user terminal. After the gas stove issues a warning, the user can adjust the heat output through the user terminal. Upon detecting the heat output adjustment command from the user terminal, the gas stove responds by adjusting the heat output accordingly.

[0060] In some embodiments, after issuing a warning when the real-time temperature reaches the warning temperature threshold, the method further includes: detecting the rotation value of the knob; and adjusting the firepower in response to the rotation value.

[0061] In this embodiment, the rotation value may include the clockwise rotation angle or the counterclockwise rotation angle of the knob.

[0062] Specifically, this embodiment addresses the user's direct adjustment of the flame by rotating a knob on the gas stove. After the gas stove issues a warning, the user can directly rotate the knob to adjust the flame. When the gas stove detects the knob rotation, it acquires the rotation value and adjusts the flame accordingly.

[0063] Step S140: Perform anti-dry burning control based on the firepower changes after the warning and the dry burning protection temperature threshold.

[0064] In this application, the changes in firepower include no change in firepower, an increase in firepower, and a decrease in firepower.

[0065] In some embodiments, the step of performing anti-dry-burning control based on the firepower change after the warning and the dry-burning protection temperature threshold includes: when the firepower change indicates that the firepower has not changed or the firepower has increased, performing continuous warning and using the dry-burning protection temperature threshold to perform anti-dry-burning control on the gas stove.

[0066] Specifically, after the gas stove issues an alarm, it detects changes in the gas stove's flame. If the flame does not change or increases, the alarm continues. When the real-time temperature of the cookware reaches the dry-burn protection temperature threshold, it enters dry-burn protection mode and controls the gas stove to automatically shut off.

[0067] In some embodiments, the step of controlling dry burning based on the change in firepower after the warning and the dry burning protection temperature threshold includes: obtaining a safe firepower level when the change in firepower indicates a decrease in firepower; and stopping the warning when the changed firepower level is not greater than the safe firepower level.

[0068] In some embodiments, after stopping the warning, the method further includes: continuously monitoring the real-time temperature after the real-time temperature is lower than the warning temperature threshold; and issuing a new warning when the real-time temperature is higher than the warning temperature threshold.

[0069] In some embodiments, the method further includes: providing a continuous warning when the changed firepower level is greater than the safe firepower level; and using the dry-burning protection temperature threshold to control the gas stove against dry burning.

[0070] In some embodiments, obtaining the safe firepower level includes: obtaining the difference between the real-time temperature and the dry-burning protection temperature threshold; obtaining the rate of change of the real-time temperature before firepower adjustment; obtaining the real-time ratio of the difference to the rate of change; obtaining the preset threshold ratio of each firepower level; and comparing the real-time ratio with the preset threshold ratio to determine the safe firepower level.

[0071] In this application, the safe heat setting is the heat setting that, after reaching the warning level and reducing the heat, will not cause the cookware to overheat.

[0072] Specifically, after the gas stove issues an alarm, the system detects changes in the stove's flame. If the flame decreases, it obtains the safe flame level. Then, it compares the changed flame level with the safe flame level. If the changed flame level is not greater than the safe flame level, the alarm stops, and the system continuously monitors the real-time temperature of the cookware to determine if the alarm value has been reached again. If the changed flame level is greater than the safe flame level, the alarm continues, and when the real-time temperature of the cookware reaches the dry-burn protection temperature threshold, the system enters dry-burn protection mode and automatically shuts off the gas stove.

[0073] The method for obtaining the safe firepower level includes: obtaining the difference ΔT between the real-time temperature of the cookware and the dry-burn protection temperature threshold when the firepower is reduced; obtaining the rate of change α of the real-time temperature of the cookware before firepower adjustment; calculating the real-time ratio of the difference ΔT to the rate of change α and obtaining the preset threshold ratio for each firepower level of the gas stove; comparing the real-time ratio with the preset threshold ratio; if the preset threshold ratio is less than the real-time ratio, it indicates that the firepower level corresponding to the preset threshold ratio is a safe firepower level.

[0074] That is, in the method provided by the present invention, the gas stove sets a warning temperature threshold and a dry-burn protection temperature threshold. Before triggering the dry-burn protection temperature threshold, the gas stove first triggers the warning temperature threshold to remind the user. After receiving the warning reminder, the user can adjust the firepower in time, reducing the probability of dry burning and alleviating the current technical problem that when the dry-burn protection is triggered, the food cooked in the pot will spoil due to excessive temperature and become inedible, resulting in waste.

[0075] The present application will now be further explained in conjunction with a specific scenario. In this scenario, a gas stove with four firepower levels will be used as an example to illustrate the control method of the gas stove provided in this application.

[0076] Figure 2 A second flowchart illustrating the control method for a gas stove provided in an embodiment of the present invention is shown, as follows: Figure 2 As shown, the gas stove control method provided in this application includes:

[0077] Step S201: Start the gas stove and initialize the dry burning protection temperature threshold and the warning temperature threshold.

[0078] In this embodiment, the warning temperature threshold is lower than the dry-burn protection temperature threshold.

[0079] Step S202: Continuously acquire the pot temperature (corresponding to the real-time temperature of the pot mentioned above).

[0080] In this embodiment, following step S201, after starting the gas stove, the real-time temperature of the cookware on the gas stove is continuously acquired.

[0081] Step S203: When the temperature of the cookware reaches the warning temperature threshold, a warning is issued to the user.

[0082] In this embodiment, when the temperature of the cookware on the gas stove reaches the warning temperature threshold, a warning is issued to alert the user.

[0083] In some embodiments, the warning method may include: light, sound, text message, application information push, etc. Specifically, the warning method can be any one of light, sound, text message, application information push, etc., or any combination of several of them.

[0084] Step S204: Does the user adjust the firepower to be reduced?

[0085] In this embodiment, it is determined whether the user has turned down the firepower of the gas stove. If the firepower is detected to have decreased, step S205 is executed; if the firepower is not detected to have decreased, step S208 is executed.

[0086] In some embodiments, the user can adjust the heat output via a user terminal. This embodiment assumes that the gas stove is wirelessly connected to the user terminal before startup, and that the gas stove and user terminal can communicate with each other.

[0087] In other embodiments, the user can adjust the flame using a knob on the gas stove.

[0088] Step S205: Calculate the current heat level that will not cause the pot to overheat (corresponding to the safe heat level mentioned above) based on the current heat level and pot temperature when the heat changes.

[0089] In this embodiment, the method for calculating the heat level that will not cause the cookware to overheat includes:

[0090] (1) Obtain the difference ΔT between the real-time temperature of the cookware and the dry-burn protection temperature threshold when the heat changes;

[0091] (2) Obtain the rate of change α of the real-time temperature of the cookware before adjusting the heat;

[0092] (3) Calculate the real-time ratio of the difference ΔT to the rate of change α, and obtain the preset threshold ratio of ΔT to α for each power level of the gas stove; compare the real-time ratio with the preset threshold ratio. If the preset threshold ratio is less than the real-time ratio, it means that the power level corresponding to the preset threshold ratio is a power level that will not cause the pot to get too hot.

[0093] Step S206: Check whether the adjusted heat level is less than or equal to the calculated result (i.e., the heat level that will not cause the cookware to overheat).

[0094] In this embodiment, it is determined whether the adjusted heat level is not greater than the heat level that will not cause the pot to overheat (i.e., the calculated result, corresponding to the safe heat level mentioned above). If the adjusted heat level is not greater than the calculated result, step S207 is executed; if the adjusted heat level is greater than the calculated result, step S208 is executed.

[0095] Step S207: Stop the warning.

[0096] In this embodiment, following step S206, the warning is stopped when it is detected that the adjusted firepower level is not greater than the calculated result.

[0097] Furthermore, after the warning is stopped, the process returns to step S202, where the gas stove continues to acquire the real-time temperature of the cookware and determines whether the warning value has been reached again.

[0098] Step S208: Continuous early warning.

[0099] In some embodiments, following step S204, if it is detected that the user has not adjusted the firepower to a lower level, then this step is executed: continuous warning.

[0100] In some embodiments, following step S206, if the adjusted firepower level is greater than the calculated result, then this step is executed: continuous warning.

[0101] Step S209: Has the temperature of the cookware reached the dry-burn protection temperature threshold?

[0102] In this embodiment, following step S208, when the gas stove is continuously issuing warnings, it is detected whether the temperature of the cookware has reached the dry-burning protection temperature threshold.

[0103] Step S210: Enter dry burning protection mode and turn off the gas stove.

[0104] In this embodiment, following step S209, when the temperature of the cookware is detected to reach the dry-burn protection temperature threshold, the dry-burn protection is activated, and the gas stove is automatically shut off.

[0105] In other words, by setting a warning temperature threshold and a dry-burn protection temperature threshold, the gas stove will first trigger the warning temperature threshold to remind the user before triggering the dry-burn protection temperature threshold. After receiving the warning reminder, the user can adjust the firepower in time, reducing the probability of dry burning and alleviating the current technical problem that food cooked in the pot will spoil due to excessive temperature when the dry-burn protection is triggered, resulting in food being wasted.

[0106] The embodiments of the present invention will be described below with reference to specific examples.

[0107] Example 1:

[0108] When a user turns on the gas stove and cooks at level 4, after the controller initializes, it obtains the warning temperature threshold of 250℃ and the dry-burn protection temperature threshold of 285℃. The preset threshold ratio of ΔT to α for each power level can be set as follows: level 4: above 38, level 3: 23-38, level 2: 8-22, level 1: below 8. The controller continuously obtains the real-time temperature of the cookware detected by the anti-dry-burn temperature probe. When the real-time temperature of the cookware reaches the warning temperature of 250℃, the controller controls the warning module to issue a warning to remind the user.

[0109] If, after receiving the warning, the user adjusts the heat level from level 4 to level 2 (i.e., the heat level decreases), the current pot temperature is 250℃. The temperature difference ΔT between this and the dry-burn protection temperature threshold of 285℃ is 35℃. Assuming the rate of change α is 1℃ / s, the real-time ratio of the difference ΔT to the rate of change α is 35. This is compared with the preset threshold ratio of ΔT to α for each heat level. This real-time ratio of 35 is within the preset threshold ratio range (23-38) for level 3. Therefore, the safe heat level is level 3. Thus, the adjusted heat level 2 is less than the safe heat level (level 3). The ratio of the difference ΔT to the rate of change α is 35, which is within the preset threshold range of the ΔT to α ratio for level 3. The adjusted heat level is level 2, which is not greater than level 3. The calculation indicates that the adjusted heat level will not cause the pot temperature to be too high, and the warning module ends the warning.

[0110] Example 2:

[0111] The user turns on the gas stove and cooks at level 3. After the controller initializes, it obtains the warning temperature threshold of 250℃ and the dry-burn protection temperature threshold of 285℃. The preset threshold ratio of ΔT to α for each power level can be set as follows: level 4: above 38, level 3: 23-38, level 2: 8-22, level 1: below 8. The controller continuously obtains the real-time temperature of the cookware detected by the anti-dry-burn temperature probe. When the cookware temperature reaches the warning temperature (250℃), the controller controls the warning module to issue a warning to alert the user.

[0112] At this time, if the user adjusts the firepower level from level 3 to level 4 after receiving the warning (i.e., the firepower changes to increase), the warning module will continue to issue warnings. When the temperature of the anti-dry burning temperature probe reaches the dry burning protection temperature threshold (285℃), it will enter the dry burning protection mode and control the gas stove to automatically turn off the flame.

[0113] Example 3:

[0114] The user turns on the gas stove and cooks at level 3. After the controller initializes, it obtains the warning temperature threshold of 250℃ and the dry-burn protection temperature threshold of 285℃. The preset threshold ratio of ΔT to α for each power level can be set as follows: level 4: above 38, level 3: 23-38, level 2: 8-22, level 1: below 8. The controller continuously obtains the real-time temperature of the cookware detected by the anti-dry-burn temperature probe. When the cookware temperature reaches the warning temperature (250℃), the controller controls the warning module to issue a warning to alert the user.

[0115] If the user does not adjust the fire level of the gas stove after receiving the warning, the warning module will continue to issue warnings and will enter dry-burn protection when the temperature of the anti-dry-burning temperature probe reaches the dry-burning protection temperature threshold (285℃), controlling the gas stove to automatically turn off the flame.

[0116] Example 4:

[0117] The user turns on the gas stove and cooks at level 3. After the controller initializes, it obtains the warning temperature threshold of 250℃ and the dry-burn protection temperature threshold of 285℃. The preset threshold ratio of ΔT to α for each power level can be set as follows: level 4: above 38, level 3: 23-38, level 2: 8-22, level 1: below 8. The controller continuously obtains the real-time temperature of the cookware detected by the anti-dry-burn temperature probe. When the cookware temperature reaches the warning temperature (250℃), the controller controls the warning module to issue a warning to alert the user.

[0118] If, after receiving the warning, the user adjusts the heat level from level 3 to level 2 (i.e., the heat level decreases), the current pot temperature is 250℃. The temperature difference ΔT between this and the dry-burn protection temperature threshold of 285℃ is 35℃. Assuming the rate of change α is 5℃ / s (i.e., the real-time ratio of the difference ΔT to the rate of change α is 7), and this real-time ratio 7 is compared with the preset threshold ratio of ΔT to α for each heat level, this real-time ratio 7 is within the preset threshold ratio range of level 1 (below 8). At this time, the safe heat level is level 1. Therefore, the adjusted heat level 2 is greater than the safe heat level (level 1). The warning module will continue to issue warnings and, when the temperature of the anti-dry-burn temperature probe reaches the dry-burn protection temperature threshold (285℃), it will enter dry-burn protection and control the gas stove to automatically shut off.

[0119] Based on the above scenario, it can be seen that in this application, the gas stove sets a warning temperature threshold and a dry-burn protection temperature threshold. Before triggering the dry-burn protection temperature threshold, the gas stove first triggers the warning temperature threshold to remind the user. After receiving the warning reminder, the user can adjust the firepower in time, reducing the probability of dry burning and alleviating the current technical problem that when the dry-burn protection is triggered, the food cooked in the pot will spoil due to excessive temperature and become inedible, resulting in waste.

[0120] Accordingly, embodiments of the present invention also provide a control device for a gas stove; Figure 3 A schematic diagram of the control device for a gas stove is shown; for example... Figure 3 As shown, the control device for the gas stove includes:

[0121] The first module 310 is used to start the gas stove and obtain the warning temperature threshold and the dry burning protection temperature threshold after receiving the start command, wherein the warning temperature threshold is less than the dry burning protection temperature threshold.

[0122] The second module 320 is used to obtain the real-time temperature of the cookware on the gas stove;

[0123] The third module 330 is used to issue an early warning when the real-time temperature reaches the warning temperature threshold.

[0124] The fourth module 340 is used to perform anti-dry-burning control based on the changes in firepower after the warning and the dry-burning protection temperature threshold.

[0125] In some embodiments, the fourth module 340 is further configured to provide a continuous early warning and use the dry-burning protection temperature threshold to control the gas stove against dry burning when the firepower change condition indicates that the firepower has not changed or the firepower has increased.

[0126] In some embodiments, the fourth module 340 is further configured to obtain a safe firepower level when the firepower change indicates a decrease in firepower; and to stop the warning when the changed firepower level is not greater than the safe firepower level.

[0127] In some embodiments, the fourth module 340 is further configured to continuously monitor the real-time temperature after the real-time temperature is less than the warning temperature threshold; and to issue a new warning after the real-time temperature is higher than the warning temperature threshold.

[0128] In some embodiments, the fourth module 340 is further configured to provide a continuous warning when the changed firepower level is greater than the safe firepower level; and to use the dry-burn protection temperature threshold to control the gas stove against dry burning.

[0129] In some embodiments, the fourth module 340 is further configured to: obtain the difference between the real-time temperature and the dry-burning protection temperature threshold; obtain the rate of change of the real-time temperature before firepower adjustment; obtain the real-time ratio of the difference to the rate of change; obtain the preset threshold ratio of each firepower level; and compare the real-time ratio with the preset threshold ratio to determine the safe firepower level.

[0130] That is, the control device of the gas stove provided in this embodiment of the invention sets a warning temperature threshold and a dry-burn protection temperature threshold. Before the gas stove triggers the dry-burn protection temperature threshold, it first triggers the warning temperature threshold to remind the user. After receiving the warning reminder, the user can adjust the firepower in time, reducing the probability of dry burning and alleviating the current technical problem that when the dry-burn protection is triggered, the food cooked in the pot will spoil due to excessive temperature and become inedible, resulting in waste.

[0131] Those skilled in the art will understand that the above-described modules or steps can be implemented using general-purpose computing devices. They can be centralized on a single computing device or distributed across a network of multiple computing devices. Optionally, they can be implemented using computer-executable program code, thereby storing them in a storage device for execution by the computing device, or fabricating them separately as individual integrated circuit modules, or fabricating multiple modules or steps into a single integrated circuit module. This invention is not limited to any specific hardware and software combination.

[0132] Accordingly, this embodiment of the invention also provides a gas stove, which includes a memory and a controller; the memory stores a computer program, and when the computer program is executed by the controller, it implements the gas stove control method as described in the above embodiments.

[0133] In this embodiment, as Figure 4 As shown, the gas stove also includes an anti-dry-burning temperature probe 410, a burner 420, a knob 430, a potentiometer 440, a gas valve shaft 450, a gas valve 460, an early warning module 470, and a controller 480. The anti-dry-burning temperature probe 410 is located in the center of the burner 420 and is used to detect the real-time temperature of the pot bottom. The anti-dry-burning temperature probe 410, potentiometer 440, and early warning module 470 are all connected to the controller 480. The potentiometer 440 is mounted on the gas valve 460. When the user operates the knob 430 to adjust the flame, the knob 430 drives the gas valve shaft 450 and the potentiometer 440 to rotate. The resistance, voltage, or current of the potentiometer 440 changes at different angles. The controller 480 detects the resistance, voltage, or current of the potentiometer 440 to achieve flame detection.

[0134] In this embodiment, the controller may be implemented using an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a Programmable Logic Device (PLD), a Field Programmable Gate Array (FPGA), a microcontroller, a microprocessor, or other electronic components, and is used to execute the methods described in the above embodiments. The methods implemented when the computer program running on the controller is executed can be referred to specific embodiments of the methods provided in the foregoing embodiments of this invention, and will not be repeated here.

[0135] Accordingly, embodiments of the present invention also provide a computer-readable storage medium storing a computer program, which, when executed by one or more controllers, implements the method described in the above embodiments:

[0136] Upon receiving the start command, the gas stove is started and the warning temperature threshold and the dry burning protection temperature threshold are obtained, wherein the warning temperature threshold is less than the dry burning protection temperature threshold.

[0137] Obtain the real-time temperature of the cookware on the gas stove;

[0138] An early warning is issued when the real-time temperature reaches the warning temperature threshold.

[0139] Dry-burn prevention control is implemented based on the changes in firepower after the warning and the dry-burn protection temperature threshold.

[0140] In this embodiment, the computer-readable storage medium can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as Static Random Access Memory (SRAM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Erasable Programmable Read-Only Memory (EPROM), Programmable Read-Only Memory (PROM), Read-Only Memory (ROM), magnetic storage, flash memory, magnetic disk, or optical disk.

[0141] In summary, this invention provides a gas stove control method and a gas stove. The method includes: upon receiving a start command, starting the gas stove and acquiring a warning temperature threshold and a dry-burn protection temperature threshold, wherein the warning temperature threshold is less than the dry-burn protection temperature threshold; acquiring the real-time temperature of the pot on the gas stove; issuing a warning when the real-time temperature reaches the warning temperature threshold; and performing anti-dry-burn control based on the change in firepower after the warning and the dry-burn protection temperature threshold. In the solution provided in this application, the gas stove sets a warning temperature threshold and a dry-burn protection temperature threshold. Before triggering the dry-burn protection temperature threshold, the gas stove first triggers the warning temperature threshold to provide a warning reminder to the user. After receiving the warning reminder, the user can adjust the firepower in a timely manner, reducing the probability of dry-burning and alleviating the current technical problem of food spoiling due to excessively high temperatures and becoming inedible when dry-burn protection is triggered.
