[0002] With the development of intelligent technology, gas stoves have gradually been upgraded from traditional cooking tools to intelligent household appliances. When users use gas stoves to cook, they need to check the cooking status every once in a while to prevent the pot from burning dry.

[0003] Currently, gas stoves are usually set with a fixed dry-burning temperature. During the cooking process, when the temperature of the pot reaches the dry-burning temperature, the gas stove can be controlled to turn off.

[0004] However, the method of using a fixed dry-boil temperature to judge whether a cookware has dry-boiled is less accurate. Summary of the Invention

[0012] The controller is configured as:

[0013] In the process of heating the pot by the flame guided through the fire outlet, the temperature of the pot detected by the temperature detection device is obtained in real time;

[0015] When the pot temperature is a second temperature, determining a time interval between the current moment and the first moment;

[0016] Determining a dry-boiling temperature corresponding to the cookware according to the time interval;

[0017] When the temperature of the pot reaches the dry-burning temperature, the gas source is controlled to be cut off to stop the flame from being drawn out through the fire outlet, so as to stop heating the pot.

[0018] In this application, when a gas stove heats a pot, the time it takes for the pot to reach a certain temperature is detected, which can be used to characterize the pot's heat conduction characteristics. Furthermore, the corresponding dry-burn temperature of the pot can be determined based on the determined time, allowing different dry-burn temperatures to be determined for different pots. Thus, when the pot reaches its corresponding dry-burn temperature, the gas stove is controlled to stop heating the pot, achieving targeted dry-burn prevention control for different pots, improving the accuracy of the anti-dry-burn prevention control, and enhancing the anti-dry-burn performance of the gas stove.

[0039] The adjustment parameter is used to adjust the temperature detected by the temperature detector obtained in real time to determine the temperature of the cookware.

[0040] In this application, the final pot temperature is obtained based on the size of the flame and the position of the temperature detector, and the detected temperature is adjusted at the same time, which can further improve the accuracy of the determined pot temperature, thereby improving the accuracy of the subsequently determined dry-burning temperature.

[0041] In some embodiments of the present application, the controller is configured to:

[0042] In the process of heating the pot by the flame guided through the fire outlet, at least two temperatures are obtained;

[0046] The first temperature detector of the at least two temperature detectors is arranged at the center of the inner fire cover, and the second temperature detector is arranged on the outer fire cover or the pot rack, wherein the second temperature detector is a temperature detector other than the first temperature detector.

[0047] In the present application, temperature detectors are respectively arranged at the center of the inner fire cover and the outer fire cover or the pot rack, so that the temperature of the side of the pot can be detected while detecting the temperature of the center of the pot rack, thereby improving the accuracy of the detected temperature and thus improving the accuracy of the subsequently determined dry-burning temperature.

[0078] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0079] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0080] In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0081] To improve safety during gas stove use, a fixed dry-burn temperature is usually set. During cooking, the temperature of the pot can be monitored in real time. When the temperature of the pot reaches the dry-burn temperature, it can be determined that the pot has dry-burned, and the gas stove is controlled to shut down.

[0082] However, a fixed dry-burn temperature is not suitable for all cookware materials. The gas stove may be turned off when there is no dry-burn, or the gas stove may be turned off only after a period of dry-burning. Therefore, the accuracy of the dry-burn prevention method using a fixed dry-burn temperature is low.

[0083] Based on this, the present application provides a gas stove and a dry-burn prevention control method. During the process of heating a pot on the gas stove, the time required for the pot to reach a certain temperature is detected, and this time can be used to characterize the pot's heat conduction characteristics. Furthermore, the corresponding dry-burn temperature of the pot can be determined based on the determined time, allowing different dry-burn temperatures to be determined for different pots. Thus, when the pot's temperature reaches its corresponding dry-burn temperature, the gas stove is controlled to stop heating the pot, achieving targeted dry-burn prevention control for different pots, improving the accuracy of the dry-burn prevention control, and enhancing the dry-burn prevention performance of the gas stove.

[0084] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. For the same or similar concepts or processes, some embodiments may not be described in detail. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0085] First, the structure of the gas stove provided in some embodiments of the present application is described.

[0086] In one possible implementation, Figure 1 FIG. 1 is a schematic structural diagram of a gas stove according to some embodiments, such as Figure 1 As shown, the gas stove 10 includes a base 101 , a burner 102 , a fire cover 103 , a pot stand 104 , and a temperature detection device 105 .

[0087] like Figure 1 As shown, the burner is mounted on the base. The fire cover is placed over the burner and has a flame outlet formed therein for directing flames through the outlet to heat the pot above the burner. The pot rack is mounted on the side of the burner and is used to support the pot above the burner.

[0088] The temperature detection device is arranged in the center of the fire cover. When the pot is placed on the pot rack, the temperature detection device contacts the bottom of the pot to detect the temperature of the pot.

[0089] Exemplarily, the temperature detection device may be an elastic device. When the pot is placed on the pot rack, the bottom of the pot contacts and presses the temperature detection device, so that the temperature detection device can more accurately detect the temperature of the pot.

[0090] In this application, the gas stove also includes a controller ( Figure 1 not shown).

[0091] In the embodiment of the present application, the controller may be a microcontroller unit (MCU) or other types of controllers. The embodiment of the present application does not specifically limit the controller.

[0092] This application is only Figure 1 The installation position of the temperature detection device shown is for illustration only and does not constitute any limitation.

[0093] Figure 2a A side view of placing a pot on a gas stove according to some embodiments Figure 1 . Figure 2b FIG2 is a second side view of placing a pot on a gas stove according to some embodiments.

[0094] Combine Figure 1 2, the following describes the anti-dry burning control method of the gas stove, which is applied to the controller of the gas stove. Figure 3 shown. Figure 3 A flow chart of a dry burning prevention control method according to some embodiments Figure 1 .

[0095] Figure 3 As shown, the anti-dry burning control method may include the following steps:

[0096] S301. While the flame guided through the fire outlet is heating the cookware, the cookware temperature detected by the temperature detection device is obtained in real time.

[0097] The temperature detection device can be an infrared sensor that detects the temperature of the cookware through infrared radiation, a thermocouple that uses the thermoelectric effect to detect the temperature of the cookware by contacting a metal probe with the bottom of the pot, or a thermistor / NTC whose resistance changes with temperature, detecting the temperature of the cookware through this change in resistance. The embodiments of this application do not specifically limit the type of temperature detection device.

[0098] When the flame guided through the fire outlet is heating the pot, the temperature detection device can obtain the temperature of the bottom of the pot, that is, the pot temperature, in real time, and the controller can obtain the pot temperature detected by the temperature detection device in real time.

[0099] S302: When the temperature of the cookware is the first temperature, determine the current first moment.

[0100] The first temperature may be 10° C. or 15° C., and the embodiment of the present application does not limit the first temperature.

[0101] For example, when the pot temperature is the first temperature,

[0102] S303: When the cookware temperature is the second temperature, determine the time interval between the current moment and the first moment.

[0103] The second temperature may be 20° C. or 25° C., and the second temperature is not limited in the present embodiment.

[0104] For example, the time it takes for the cookware temperature to rise from a first temperature to a second temperature can be determined by timing, that is, the time interval between the current moment and the first moment. Specifically, timing can be started when the cookware temperature reaches the first temperature, and stopped when the cookware temperature reaches the second temperature, and the timing duration is determined as the time interval between the current moment and the first moment.

[0105] S304: Determine the dry-boiling temperature corresponding to the cookware according to the time interval.

[0106] Exemplarily, the controller pre-stores a correspondence between the time interval and the dry-boiling temperature, so that when the time interval is obtained, the dry-boiling temperature corresponding to the cookware can be determined.

[0107] The correspondence between time intervals and dry-boil temperatures can be pre-determined and stored through multiple experiments. Since cookware with different heat conductivity characteristics has corresponding dry-boil temperatures that vary, and the time interval required for the cookware's temperature to rise to a certain value can reflect the cookware's heat conductivity characteristics, the present application can determine the corresponding dry-boil temperatures for cookware with different heat conductivity characteristics.

[0108] When the temperature of the pot does not reach the dry-burning temperature, the gas stove can heat the pot normally.

[0109] It should be noted that the time interval is proportional to the dry-burning temperature.

[0110] S305: When the temperature of the pot reaches the dry-burning temperature, the gas source is controlled to stop being discharged through the fire outlet, thereby stopping heating the pot.

[0111] Specifically, the solenoid valve or other type of control valve of the gas stove can be controlled to be closed to cut off the gas source, stop the flame from being guided through the fire hole, and thus stop heating the pot.

[0112] Thus, the anti-dry-burn control method provided by this application detects the time required for the cookware to reach a certain temperature during the process of heating the cookware by the gas stove. This time can be used to characterize the heat conduction characteristics of the cookware. Furthermore, the corresponding dry-burn temperature of the cookware can be determined based on the determined time, so that different dry-burn temperatures can be determined for different cookware. In this way, when the temperature of the cookware reaches its corresponding dry-burn temperature, the gas stove is controlled to stop heating the cookware, achieving targeted anti-dry-burn control for different cookware, improving the accuracy of the anti-dry-burn control, and enhancing the anti-dry-burn performance of the gas stove.

[0113] In the present application, the controller determining the dry-boiling temperature corresponding to the cookware according to the time interval may include: the controller determining the dry-boiling temperature corresponding to the cookware according to the corresponding relationship between the time interval and the target.

[0114] The target correspondence is a correspondence between a plurality of preset time interval ranges and dry-burning temperatures. In the correspondence, the time interval range is proportional to the dry-burning temperature.

[0115] Specifically, the controller can determine the preset time interval range in which the time interval is located within multiple preset time interval ranges in the target correspondence, and further determine the dry-boiling temperature corresponding to the preset time interval range, that is, determine the dry-boiling temperature corresponding to the cookware.

[0116] Exemplarily, the target correspondence relationship is pre-stored, and the embodiment of the present application does not specifically limit the target correspondence relationship.

[0117] In this way, the corresponding dry-boiling temperature is determined according to the pre-stored correspondence between the time and the dry-boiling temperature, so that the determined dry-boiling temperature can meet the heat conduction characteristics of the cookware.

[0119] S401, standby.

[0120] S402, ignition and startup.

[0121] S403: Detect the temperature of the cookware.

[0122] S404: Is the pot temperature greater than or equal to Temp1?

[0123] Temp1 is the first temperature described in the above embodiment.

[0124] If the pot temperature is greater than or equal to Temp1, the following step S405 may be executed. If the pot temperature is less than Temp1, the following step S403 may be executed.

[0125] S405: Is the pot temperature greater than or equal to Temp2?

[0126] If the pot temperature is greater than or equal to Temp2, the following step S406 may be executed. If the pot temperature is less than Temp2, the following step S403 may be executed.

[0127] Temp2 is the second temperature described in the above embodiment.

[0128] S406: Determine the time interval and judge whether the time interval is greater than Time3.

[0129] The time interval is the time interval between the moment when the pot temperature is detected to be greater than or equal to Temp1 and the moment when the pot temperature is detected to be greater than or equal to Temp2.

[0130] Time3 can be 1 minute or 2 minutes, and this embodiment of the application does not specifically limit Time3.

[0131] If the time interval is greater than Time3, the following step S408 may be executed. If the time interval is less than or equal to Time3, the following step S407 may be executed.

[0132] S407: Determine that the dry-boiling protection trigger condition is Temp3.

[0133] Temp3 is the dry-burning temperature described in the above embodiment.

[0134] S408: Determine that the dry-boiling protection trigger condition is Temp4.

[0135] Temp4 is the dry-burning temperature described in the above embodiment.

[0136] Among them, Temp4 is greater than Temp3.

[0137] In this way, the dry-boiling temperature of any pot placed on the gas stove can be determined.

[0138] In this application, the dry-boiling temperature corresponding to the pot can be determined according to the time interval in combination with the target correspondence. Figure 5 As shown, Figure 5 Schematic diagram 2 of a flow chart of an anti-dry burning control method according to some embodiments.

[0139] like Figure 5 As shown, determining the dry-burn temperature may include the following steps:

[0140] S501: Obtain the type of the pot above the fire cover.

[0141] The type of cookware may include the material, size, bottom shape, etc. of the cookware. This application does not limit the specific type of cookware.

[0142] Acquiring the cookware type may include the following manner: when the user places the cookware on the pot rack, the user may input the cookware type, so that the controller acquires the cookware type input by the user.

[0143] Exemplarily, the user inputting the cookware type may include the following possible implementations:

[0144] In one possible implementation, a plurality of buttons for the types of pots are provided on the gas stove. After the user places the pot on the pot rack, he or she can perform an operation on the button corresponding to the type of pot to input the type of pot.

[0145] Another possible implementation is that a voice module can be provided on the gas stove. When the user places the pot on the pot rack, he can speak a voice containing the type of pot. The voice module can collect the user's voice to obtain the pot type.

[0146] In another possible implementation, the gas stove can be linked to the range hood, and the user can input the pot type through the range hood display or voice input. The range hood can send the pot type to the gas stove controller so that the controller can obtain the pot type.

[0147] The embodiments of the present application are merely described using the above-mentioned possible methods of obtaining the type of cookware as examples, and do not constitute any limitation.

[0148] S502: Determine a target correspondence relationship corresponding to the cookware type from a plurality of preset correspondence relationships according to the cookware type.

[0149] In this application, a corresponding relationship between a time interval range and a dry-boiling temperature can be stored for each type of cookware.

[0150] After the controller obtains the cookware type, it can determine the target correspondence relationship corresponding to the cookware type, so that the dry-boil temperature subsequently determined based on the target correspondence relationship is more accurate.

[0151] S503: Determine a first temperature and a second temperature corresponding to the cookware type according to the cookware type.

[0152] The controller may also store the corresponding relationship between the cookware, the first temperature and the second temperature. After the controller obtains the type of cookware, it may obtain the corresponding first temperature and second temperature according to the type of cookware.

[0153] In this way, for different types of cookware, different first temperatures and second temperatures can be used to determine the time interval for the temperature rise, thereby further improving the accuracy of the subsequently determined dry-boil temperature of the cookware.

[0154] S504: When the cookware temperature is the first temperature, determine the current first moment; when the cookware temperature is the second temperature, determine the time interval between the current moment and the first moment.

[0155] The method for determining the time interval can be found in the above embodiment and will not be described in detail here.

[0156] S505: Determine the dry-boiling temperature corresponding to the cookware according to the corresponding relationship between the time interval and the target.

[0157] The method for determining the dry-burning temperature can be found in the above embodiment and will not be described in detail here.

[0158] S506: When the temperature of the pot reaches the dry-burning temperature, the gas source is controlled to stop being discharged through the fire outlet, thereby stopping heating the pot.

[0159] The method of controlling the gas source to stop the flame from being discharged through the fire outlet can be referred to the above embodiment and will not be described in detail here.

[0160] In this way, the dry-burning temperature can be determined and the anti-dry-burning control can be carried out for different types of pots, making the anti-dry-burning control more precise, thereby improving the anti-dry-burning performance of the gas stove.

[0161] For the different preset time intervals described in the above embodiment, the confirmation of the dry burning temperature of the gas stove can be referred to Figure 6 As shown, Figure 6 FIG2 is a second flow chart of a method for determining a dry-boiling trigger condition according to some embodiments.

[0168] If the pot temperature is greater than or equal to Temp1, the following step S605 may be executed. If the pot temperature is less than Temp1, the following step S603 may be executed.

[0169] S605: Is the pot temperature greater than or equal to Temp2?

[0170] Temp2 is the second temperature described in the above embodiment.

[0171] If the pot temperature is greater than or equal to Temp2, the following step S606 may be executed. If the pot temperature is less than Temp2, the following step S603 may be executed.

[0172] S606: Determine the time interval and judge whether the time interval is greater than Time3.

[0173] The time interval is the time interval between the moment when the pot temperature is detected to be greater than or equal to Temp1 and the moment when the pot temperature is detected to be greater than or equal to Temp2.

[0174] Time3 can be 3 minutes or 4 minutes. This embodiment of the application does not specifically limit Time3.

[0175] If the time interval is greater than Time3, step S607 is executed; if the time interval is not greater than Time3, step S608 is executed.

[0176] S607: Determine that the dry-boiling protection trigger condition is Temp4.

[0177] Temp4 is the dry-burning temperature described in the above embodiment.

[0179] Among them, Time2 is smaller than Time3.

[0180] Time2 can be 2 minutes or 1 minute. This embodiment of the application does not specifically limit Time2.

[0184] S6010: Determine whether the time interval is greater than Time1.

[0185] Among them, Time1 is smaller than Time2.

[0186] Time1 can be 2 minutes or 1 minute. This embodiment of the application does not specifically limit Time2.

[0187] If the time interval is greater than Time1, step S6011 is executed; if the time interval is not greater than Time1, step S6012 is executed.

[0188] S6011. Determine that the dry-boiling protection trigger condition is Temp6.

[0189] Temp6 is the dry-burning temperature described in the above embodiment, and Temp6 is less than Temp6.

[0190] S6012: Determine that the dry-boiling protection trigger condition is Temp3.

[0191] Temp3 is the dry-burning temperature described in the above embodiment, and Temp3 is less than Temp6.

[0192] In this way, time intervals of different levels can be set to determine different dry-burning temperatures, and the dry-burning temperature can be determined for any pot placed on the gas stove.

[0193] In this application, after the controller obtains the temperature of the pot detected by the temperature detection device, it can adjust the temperature to improve the accuracy of the obtained temperature. Figure 7 As shown, Figure 7 A flow chart of a method for determining the temperature of a cookware according to some embodiments Figure 1 .

[0194] like Figure 7 As shown, the method for determining the temperature of a cookware may include the following steps:

[0195] S701: Obtain parameters of the flame derived from the fire outlet, where the parameters are used to represent the size of the flame.

[0196] For example, the flame parameter may be the current gear position of the gas stove. Different gear positions indicate different sizes of flames emitted from the fire outlet of the gas stove, that is, different temperatures of the flames.

[0197] S702: Determine an adjustment parameter according to the flame parameter, where the adjustment parameter is inversely proportional to the flame size.

[0198] For example, the adjustment parameter can be a value between 0 and 1. Since the larger the flame, the higher the flame temperature, the greater the impact on the temperature detection device. Therefore, the adjustment parameter is inversely proportional to the flame size. The embodiment of the present application does not limit the specific adjustment parameter.

[0199] S703: Using the adjustment parameters, adjust the temperature detected by the temperature detection device in real time to determine the temperature of the cookware.

[0200] For example, the product of the adjustment parameter and the temperature detected by the temperature detection device may be calculated, and the product may be determined as the pot temperature.

[0201] In this way, the temperature detected by the temperature detection device is adjusted according to the flame size, so that the final pot temperature is less affected by the gas stove flame, which can improve the accuracy of the determined pot temperature and thus improve the accuracy of the subsequently determined dry-burning temperature.

[0202] In the present application, the fire cover includes an inner fire cover 21 and an outer fire cover 22, and the temperature detection device includes at least two temperature detectors.

[0203] The first temperature detector of the at least two temperature detectors is arranged at the center of the inner fire cover, and the second temperature detector is arranged on the outer fire cover or the pot rack, wherein the second temperature detector is a temperature detector other than the first temperature detector.

[0204] The temperature detection device includes at least two temperature detectors. The locations of the at least two temperature detection devices can be found in Figures 8-10 shown. Figure 8 Schematic diagram of the location of a temperature detector according to some embodiments Figure 1 , Figure 9 FIG2 is a second schematic diagram of a setting position of a temperature detector according to some embodiments. Figure 10 Schematic diagram of the location of a temperature detector according to some embodiments Figure 3 .

[0205] Take the temperature detection device including three temperature detectors as an example, Figure 8 As shown, one temperature detector is set at the center of the fire cover, the other two are set on the outer fire cover, and the three temperature detectors are arranged in a straight line.

[0206] Take the temperature detection device including 4 temperature detectors as an example, Figure 9 As shown, one temperature detector is set in the center of the fire cover, and the other three are set on the outer fire cover.

[0207] Take the temperature detection device including 5 temperature detectors as an example, Figure 10 As shown, one temperature detector is arranged at the center of the fire cover, and the other four are arranged at the four corners of the pot rack.

[0208] In this way, temperature detectors are respectively arranged at the center of the inner fire cover and the outer fire cover or the pot rack, so that the temperature of the side of the pot can be detected while detecting the temperature of the center of the pot rack, thereby improving the accuracy of the detected temperature and thus improving the accuracy of the dry-burning temperature determined subsequently.

[0209] In an embodiment of the present application, the controller obtains at least two temperatures during the process of heating the pot by the flame guided through the fire outlet; and determines the pot temperature based on the at least two temperatures.

[0210] Exemplarily, determining the temperature of the cookware according to at least two temperatures may include the following possible implementations:

[0211] In a possible implementation, an average value of at least two temperatures may be calculated and the average value may be determined as the pot temperature.

[0212] In another possible implementation, a corresponding coefficient can be determined based on the location of the temperature detector. The coefficient is between 0 and 1. The product of the coefficient of the temperature detector and the detected temperature is calculated to obtain at least two products, and the sum of the at least two products is determined as the pot temperature.

[0213] The closer the temperature detector is to the center of the pot bottom, the greater the effectiveness of the temperature it detects, and therefore, the larger the corresponding coefficient.

[0214] In this way, the cookware temperature is determined based on the values ​​detected by multiple temperature detectors, which can effectively improve the accuracy of the determined cookware temperature.

[0215] In another possible implementation, based on the temperature detection device including at least two temperature detectors, the temperature can be adjusted according to the size of the flame and the location of the temperature detector to determine the temperature of the pot. Figure 11 As shown, Figure 11 FIG2 is a second flow chart of another method for determining the temperature of a cookware according to some embodiments.

[0216] like Figure 11 As shown, the method for determining the temperature of a cookware may include the following steps:

[0217] S1101. Acquire at least two temperatures during the process of heating the cookware by the flame guided through the fire outlet.

[0218] The at least two temperatures are respectively acquired by at least two temperature detectors.

[0219] S1102. Determine adjustment parameters according to flame parameters and preset parameters of the temperature detector.

[0220] The parameters of the flame can be found in the above embodiment and will not be described in detail here.

[0221] The preset parameter represents the extent to which the temperature detected by the temperature detector is affected by the flame from the ignition hole, and is related to the distance between the temperature detector and the center of the flame cover. The adjustment parameter is inversely proportional to the flame size.

[0222] Exemplarily, the preset coefficient may be a value within the range of 0-1.

[0223] The closer the temperature detector is to the flame, the greater the effect of the flame on the temperature it detects. Furthermore, the closer the temperature detector is to the center of the flame cover, that is, the closer it is to the center of the pot, the greater the effectiveness of the temperature it detects.

[0224] For example, the product of the flame parameter and the preset parameter may be calculated and the product may be determined as the adjustment parameter. Alternatively, the adjustment parameter may be determined in other ways, which are not limited in the present embodiment.

[0225] S1103: Using adjustment parameters, adjust at least two temperatures detected by the temperature detector in real time to determine the temperature of the cookware.

[0226] Exemplarily, the product of the adjustment coefficient and the detected temperature may be calculated to obtain at least two products, and the sum of the at least two products may be determined as the pot temperature.

[0227] In this way, the final pot temperature is obtained by adjusting the detected temperature according to the flame size and the position of the temperature detector, which can further improve the accuracy of the determined pot temperature and thus improve the accuracy of the subsequently determined dry-boil temperature.

[0228] It should be understood that after determining the pot temperature, the dry-boiling temperature can be further determined. Detailed descriptions can be made in the above embodiments and will not be repeated here.
