Description

Technical Field

[0001] This invention relates to the field of home appliance control technology, and in particular to a protection method and related components for abnormal cooking in an electric pressure cooker. Background Technology

[0002] Electric pressure cookers are upgraded versions of traditional pressure cookers and rice cookers, combining the advantages of both while effectively solving the safety issues associated with traditional pressure cookers. Electric pressure cookers typically include multiple cooking modes. Different types of food require different heating methods and therefore different cooking modes. If a user mistakenly uses a cooking mode incompatible with the food being cooked, the pressure cooker may overheat or even be damaged. For example, the saute mode, also known as the tender sautéing mode, is a commonly used mode. This mode typically sets the cooking temperature above 100 degrees Celsius, causing the pressure cooker to operate at a higher power. However, if the user selects this mode to cook porridge or foods with high water content, the food may not reach the set cooking temperature quickly enough, causing the pressure cooker to continuously increase its power, resulting in overheating and shortening the pressure cooker's lifespan. Summary of the Invention

[0003] The purpose of this invention is to provide a protection method and related components for abnormal cooking in electric pressure cookers, which can prevent the electric pressure cooker from overheating due to improper operation by the user, causing it to continuously increase power and fail to reach the cooking set temperature.

[0004] To address the aforementioned technical problems, this invention provides a protection method for abnormal cooking in an electric pressure cooker, comprising:

[0005] After starting the electric pressure cooker, determine the initial temperature of the food to be cooked inside the electric pressure cooker;

[0006] The cooking protection time of the electric pressure cooker is adjusted according to the initial temperature, wherein the initial temperature is negatively correlated with the cooking protection time;

[0007] The heating module in the electric pressure cooker is controlled to start heating at a first preset working power, and when the heating time is longer than the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is lower than the target temperature, the heating module is controlled to heat at a second preset working power, wherein the second preset working power is less than the first preset working power.

[0008] Preferably, after controlling the heating module to heat at a second preset operating power, the method further includes:

[0009] The heating module is controlled to stop working when it continues to heat at the second preset working power until the electric pressure cooker meets the preset cooking end conditions.

[0010] Preferably, after controlling the heating module in the electric pressure cooker to start heating at a first preset operating power, the method further includes:

[0011] When the heating time is not greater than the cooking protection time, the step of controlling the heating module in the electric pressure cooker to start working at a first preset working power is initiated.

[0012] When the heating time is longer than the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is not less than the target temperature, the heating module is controlled to continue heating at the first preset working power until the electric pressure cooker meets the preset cooking end conditions, at which point the heating module is controlled to stop working.

[0013] Preferably, after controlling the heating module in the electric pressure cooker to start heating at a first preset operating power, the method further includes:

[0016] If not, it is determined that the electric pressure cooker is set to the low-temperature cooking function, and the electric pressure cooker is controlled to work at the fourth preset working power until the electric pressure cooker meets the preset cooking end condition, and the heating module is controlled to stop working, wherein the fourth preset working power is less than the first preset working power.

[0017] Preferably, before controlling the electric pressure cooker to stop working when the preset cooking end condition is met, the method further includes:

[0019] The preset working power corresponding to the temperature range is used as the final cooking power of the heating module, and the heating module is controlled to continue heating at the final cooking power. Then, the electric pressure cooker is controlled to stop working when the preset cooking end condition is met. The current temperature is negatively correlated with the final cooking power.

[0020] When the temperature of the bottom of the electric pressure cooker does not reach the preset protection temperature, the process enters the step of controlling the heating module in the electric pressure cooker to start heating at the first preset working power.

[0021] Preferably, when the electric pressure cooker meets the preset cooking end conditions, controlling the electric pressure cooker to stop working includes:

[0022] When the temperature of the bottom of the electric pressure cooker reaches the cooking set temperature, the heating module is controlled to stop working, and it is determined whether the total heating time from the start of heating to the current moment has reached the cooking set time.

[0040] In summary, this invention discloses a protection method and related components for abnormal cooking in an electric pressure cooker, relating to the field of home appliance control technology. After the electric pressure cooker is started, the initial temperature of the food to be cooked is first determined. Then, the cooking protection time of the electric pressure cooker is adjusted according to the initial temperature, and the initial temperature and the cooking protection time are negatively correlated. After determining the cooking protection time, the electric pressure cooker is controlled to start heating at a first preset power. If the heating time reaches the cooking protection time but the actual temperature of the bottom of the electric pressure cooker has not yet reached the target temperature, it indicates that the food to be cooked is difficult to heat. Therefore, the power of the electric pressure cooker is reduced to a second preset working power, thereby avoiding the problem of the electric pressure cooker continuously increasing its power due to its inability to reach the set cooking temperature, ultimately leading to excessive temperature rise.

[0045] Figure 4 This is a schematic diagram of a protective device for abnormal cooking in an electric pressure cooker provided by the present invention. Detailed Implementation

[0046] The core of this invention is to provide a protection method and related components for abnormal cooking in electric pressure cookers, which can prevent the electric pressure cooker from failing to reach the cooking set temperature due to improper operation by the user, causing the power to continuously increase and eventually leading to excessive temperature rise in the electric pressure cooker.

[0047] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] In existing technologies, when users mistakenly use a cooking mode that is not compatible with the food to be cooked, the electric pressure cooker may overheat or even be damaged. For example, when a user selects the Saute mode, the electric pressure cooker will heat the food to be cooked to a higher temperature. However, if the food actually placed in the electric pressure cooker is porridge or food with a high water content, which is not easy to heat, the electric pressure cooker will continuously increase its working power in order to reach a higher temperature, which will lead to the electric pressure cooker overheating or even being damaged.

[0049] Please refer to Figure 1 , Figure 1 This is a flowchart illustrating a protection method for abnormal cooking in an electric pressure cooker provided by the present invention. The control method includes:

[0050] S1: Determine the initial temperature of the food to be cooked inside the electric pressure cooker after starting the pressure cooker;

[0051] S2: Adjust the cooking protection time of the electric pressure cooker according to the initial temperature, wherein the initial temperature and the cooking protection time are negatively correlated;

[0052] Considering that existing technologies may cause malfunctions due to the inability to adjust the operating power of electric pressure cookers according to the characteristics of the food being cooked, this application determines the type of food by detecting whether the food reaches the target temperature after being heated for a period of time (i.e., the cooking protection time in this application). The operating power of the electric pressure cooker is then adjusted according to the type of food. For example, when the food is difficult to heat, the operating power of the electric pressure cooker is automatically reduced to allow the food to heat slowly, thus avoiding the problem of the electric pressure cooker rapidly and continuously increasing its operating power because it detects that the bottom temperature of the pot has not reached the target temperature.

[0053] Specifically, considering that the initial temperature of the food to be cooked affects whether it can reach the target temperature after being heated for a period of time, it is necessary to first determine the initial temperature of the food to be cooked in order to improve the accuracy of determining the type of food to be cooked, and then adjust the cooking protection time according to the initial temperature. Furthermore, the initial temperature and the cooking protection time are negatively correlated; the higher the initial temperature, the shorter the cooking protection time, and the lower the initial temperature, the longer the cooking protection time.

[0054] In this application, the initial temperature of the food to be cooked in the electric pressure cooker is determined specifically by controlling the electric pressure cooker to operate at a third preset power after the pressure cooker is started. This third preset power can be a relatively high power to quickly raise the temperature of the bottom of the pressure cooker to the preset temperature value, thereby improving the efficiency of determining the initial temperature. For example, the third preset power can be the rated power of the electric pressure cooker. Then, the operating time of the electric pressure cooker operating at the third preset power is determined when the temperature of the bottom of the pot reaches the preset temperature value. The lower the initial temperature of the food to be cooked, the longer the operating time required for the electric pressure cooker to raise the temperature of the bottom of the pot to the preset temperature value using the third preset power, and vice versa. Therefore, the initial temperature of the food to be cooked can be determined based on the range of operating times. Specifically, this application determines the preset temperature value corresponding to the range of operating times as the initial temperature of the food to be cooked, and then uses the preset cooking protection time corresponding to the initial temperature range as the cooking protection time of the electric pressure cooker.

[0055] It should also be noted that the cooking protection time in this application refers to the duration for which the heating module in the electric pressure cooker heats at the first preset working power. This duration can be used to determine whether the type of food to be cooked is difficult to heat or easy to heat, and thus the power of the electric pressure cooker can be adjusted according to the type of food to be cooked, that is, the electric pressure cooker can be protected according to the type of food to be cooked.

[0056] For example, when the working time is less than 300 seconds, set the cooking protection time to 3 to 10 minutes; when the working time is between 300 and 600 seconds, set the cooking protection time to 10 to 20 minutes; and when the working time is greater than 600 seconds, set the cooking protection time to 20 to 30 minutes.

[0057] S3: Control the heating module in the electric pressure cooker to start heating at the first preset working power, and when the heating time is longer than the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is lower than the target temperature, control the heating module to heat at the second preset working power, wherein the second preset working power is less than the first preset working power;

[0058] After determining the cooking protection time, the heating module in the electric pressure cooker is controlled to start heating the electric pressure cooker at a first preset working power. The specific value of the first preset working power is not particularly limited in this application. For example, the first preset working power is 90% of the rated power of the electric pressure cooker, and the third preset working power is the rated power of the electric pressure cooker.

[0059] If the heating time exceeds the cooking protection time and the actual temperature of the bottom of the electric pressure cooker has not yet reached the target temperature, it proves that the food to be cooked is porridge or a type of food with a high water content that is difficult to heat. Therefore, in this application, the heating module in the electric pressure cooker is controlled to heat the electric pressure cooker with a second preset working power, and the second preset working power is less than the first preset working power. That is, after determining that the food to be cooked is a type of food that is difficult to heat, the working power of the electric pressure cooker is automatically reduced, thereby avoiding the problem that the electric pressure cooker will continuously increase its power due to the fact that it cannot reach the cooking setting temperature corresponding to the cooking mode for a long time, eventually leading to the problem of the electric pressure cooker overheating.

[0060] It should also be noted that the preset cooking end condition can be that the working time of the electric pressure cooker reaches the preset cooking time and / or the temperature of the bottom of the electric pressure cooker reaches the preset cooking temperature. This application does not make any special limitation on this.

[0061] In summary, this invention provides a protection method and related components for abnormal cooking in an electric pressure cooker, relating to the field of home appliance control technology. After the electric pressure cooker is started, the initial temperature of the food to be cooked is first determined. Then, the cooking protection time of the electric pressure cooker is adjusted according to the initial temperature, and the initial temperature and the cooking protection time are negatively correlated. After determining the cooking protection time, the electric pressure cooker is controlled to start heating at a first preset power. If the heating time reaches the cooking protection time but the actual temperature of the bottom of the electric pressure cooker has not yet reached the target temperature, it indicates that the food to be cooked is difficult to heat. Therefore, the power of the electric pressure cooker is reduced to a second preset working power, thereby avoiding the problem of the electric pressure cooker continuously increasing its power due to its inability to reach the set cooking temperature, ultimately leading to excessive temperature rise.

[0062] Based on the above embodiments:

[0063] In a preferred embodiment, after controlling the heating module to heat at a second preset operating power, the method further includes:

[0064] The heating module continues to heat at the second preset working power until the electric pressure cooker meets the preset cooking end conditions, at which point the heating module is controlled to stop working.

[0065] In this embodiment, once it is determined that the food to be cooked is of a type that is difficult to heat, and the heating module is controlled to operate at a second preset power to ensure the electric pressure cooker can function properly, the electric pressure cooker is within a relatively safe range. Therefore, the heating module is controlled to continue operating at the second preset power until the electric pressure cooker meets the preset cooking end condition, at which point the heating module is controlled to stop operating. This embodiment does not specifically limit the preset cooking end condition; for example, the preset cooking end condition could be that the electric pressure cooker's operating time reaches the preset cooking time and / or the temperature of the bottom of the electric pressure cooker reaches the preset cooking temperature.

[0066] In a preferred embodiment, after the heating module in the electric pressure cooker starts heating at a first preset operating power, it further includes:

[0067] The step of starting heating at the first preset working power in the electric pressure cooker when the heating time is not greater than the cooking protection time;

[0068] When the heating time exceeds the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is not lower than the target temperature, the heating module is controlled to continue heating at the first preset working power until the electric pressure cooker meets the preset cooking end conditions, at which point the heating module is controlled to stop working.

[0069] Please refer to Figure 2 , Figure 2 This is a flowchart illustrating another method for protecting an electric pressure cooker from abnormal cooking provided by the present invention. In this embodiment, to further optimize the function of the electric pressure cooker, after detecting that the electric pressure cooker has started heating at a first preset working power, if it is determined that the heating time has not reached the cooking protection time, the electric pressure cooker continues to be controlled to heat at the first preset working power; if it is determined that the heating time is greater than the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is not less than the target temperature, it proves that the food to be cooked does not belong to the category of foods with high water content and difficult to heat, such as porridge, that is, the food to be cooked is matched with the cooking mode of the electric pressure cooker. Therefore, the heating module in the electric pressure cooker can be kept at the first preset working power until the electric pressure cooker stops working when the preset cooking end condition is met.

[0070] It should also be noted that if the heating time is longer than the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is not lower than the target temperature, and the first preset working power is set relatively high, the working power of the heating module can be reduced. The heating module will be controlled to work at the reduced working power until the electric pressure cooker stops working when the preset cooking end conditions are met.

[0071] In a preferred embodiment, after the heating module in the electric pressure cooker starts heating at a first preset operating power, it further includes:

[0072] Obtain the cooking setting temperature of the electric pressure cooker and determine whether the cooking setting temperature is greater than the preset cooking function temperature.

[0073] If so, it is determined that the electric pressure cooker is set to high-temperature cooking function, and the process proceeds to the step of controlling the heating module to heat at the second preset working power when the heating time is longer than the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is less than the target temperature.

[0074] If not, it is determined that the electric pressure cooker is set to the low-temperature cooking function, and the electric pressure cooker is controlled to work at the fourth preset working power until the electric pressure cooker meets the preset cooking end conditions and the heating module is controlled to stop working, wherein the fourth preset working power is less than the first preset working power.

[0075] Considering that the problem of excessive temperature rise in electric pressure cookers due to the cooker continuously increasing its power before reaching the set cooking temperature mainly occurs when the user uses the high-temperature cooking function, this embodiment, after controlling the electric pressure cooker to start heating at the first preset working power, first determines whether the electric pressure cooker is currently in a high-temperature or low-temperature cooking function. If the electric pressure cooker is currently in a low-temperature cooking function, it is not necessary to determine whether the food to be cooked is a type of food that is difficult to heat, thus improving the working efficiency of the electric pressure cooker. Please refer to... Figure 2 , Figure 2 This is a flowchart illustrating another method for protecting an electric pressure cooker from abnormal cooking, provided by the present invention.

[0076] Electric pressure cookers use different power levels to heat food in their high-temperature cooking and low-temperature cooking functions. Generally, the high-temperature cooking function means that the electric pressure cooker adjusts its power to keep the food at 100 degrees Celsius or higher, while the low-temperature cooking function means that the electric pressure cooker adjusts its power to keep the food at 100 degrees Celsius or lower.

[0077] Specifically, the process first obtains the cooking setting temperature of the electric pressure cooker, then determines whether the cooking setting temperature is greater than the preset cooking function division temperature. It should be noted that the cooking setting temperature is the temperature corresponding to the cooking mode selected by the user, and the preset cooking function division temperature is a temperature set by the developers in the electric pressure cooker to distinguish cooking modes; for example, the preset cooking function division temperature is 100 degrees Celsius. When the cooking setting temperature is greater than the preset cooking function division temperature, i.e., the electric pressure cooker is set to high-temperature cooking function by the user, the process proceeds to the step of controlling the electric pressure cooker to heat at a second preset working power when the heating time exceeds the cooking protection time and the actual temperature of the bottom of the electric pressure cooker is less than the target temperature. This step also involves determining whether the food to be cooked is a type of food that is difficult to heat. When the cooking setting temperature is not greater than the preset cooking function division temperature, i.e., the electric pressure cooker is set to low-temperature cooking function, the process controls the electric pressure cooker to operate at a fourth preset working power, and the electric pressure cooker stops working when the preset cooking end conditions are met. It should be noted that reducing the working power of the electric pressure cooker when it is determined to be set to low-temperature cooking function is to ensure the conditions for low-temperature cooking; this application does not specifically limit the value of the fourth preset working power.

[0078] As a preferred embodiment, before controlling the electric pressure cooker to stop working when the preset cooking end conditions are met, the method further includes:

[0079] When the temperature of the bottom of the electric pressure cooker reaches the preset protection temperature, determine the current temperature range of the bottom of the electric pressure cooker.

[0080] The preset working power corresponding to the temperature range is used as the final cooking power of the heating module, and the heating module is controlled to continue heating at the final cooking power. When the electric pressure cooker meets the preset cooking end conditions, the electric pressure cooker is controlled to stop working. The current temperature is negatively correlated with the final cooking power.

[0081] When the temperature of the bottom of the electric pressure cooker has not reached the preset protection temperature, the process enters the step of controlling the heating module in the electric pressure cooker to start heating at the first preset working power.

[0082] Considering that the cooking protection time varies depending on the initial temperature of the food to be cooked when the electric pressure cooker starts working, there may be a problem of the temperature being too low when cooking food normally. Therefore, in this embodiment, the working power of the heating module is readjusted according to the temperature of the bottom of the pot to ensure the temperature of the food to be cooked.

[0083] Please refer to Figure 2 , Figure 2This invention provides a schematic flowchart of another protection method for abnormal cooking in an electric pressure cooker. Specifically, when the temperature of the bottom of the electric pressure cooker reaches the preset protection temperature, the current temperature range of the bottom is first determined. The preset working power corresponding to this temperature range is then used as the final cooking power of the electric pressure cooker. It should also be noted that the current temperature of the bottom and the final cooking power are negatively correlated; that is, the lower the current temperature of the bottom, the higher the final cooking power. For example, when the current temperature of the bottom is less than 100 degrees Celsius, the final cooking power is adjusted to 50% of the rated power; when the current temperature of the bottom is between 100 and 130 degrees Celsius, the final cooking power is adjusted to 40% of the rated power; and when the current temperature of the bottom is between 130 and 160 degrees Celsius, the final cooking power is adjusted to 30% of the rated power. The more ranges defined, the more precise the control of the electric pressure cooker. The above ranges can be adjusted according to the actual usage scenario, and this application does not impose any particular limitations on them.

[0084] As a preferred embodiment, controlling the electric pressure cooker to stop working when the preset cooking end conditions are met includes:

[0085] When the temperature of the bottom of the electric pressure cooker reaches the cooking set temperature, the electric pressure cooker is controlled to stop working, and it is determined whether the total heating time from the start of heating to the current moment has reached the cooking set time.

[0086] The electric pressure cooker will stop working when the total heating time reaches the set cooking time.

[0087] If the total heating time has not reached the set cooking time, proceed to the step of determining the current temperature range of the bottom of the electric pressure cooker.

[0088] In this embodiment, the preset cooking end condition that needs to be met when the electric pressure cooker stops working is that the temperature of the bottom of the electric pressure cooker reaches the cooking set temperature and the total heating time of the heating module reaches the cooking set time, where the cooking set temperature and cooking set time are the temperature and time corresponding to the cooking mode set by the user. Specifically, firstly, it is determined whether the temperature of the bottom of the pot has reached the cooking set temperature. If the temperature of the bottom of the pot reaches the cooking set temperature, the electric pressure cooker is controlled to stop working. Then, it is further determined whether the total heating time of the heating module has reached the cooking set time. If the total heating time has also reached the cooking set time, it is determined that the electric pressure cooker meets the preset cooking end condition, and the electric pressure cooker is controlled to stop working. If the total heating time has not reached the cooking set time, the temperature range of the current temperature of the bottom of the electric pressure cooker is determined again, so as to readjust the final cooking power of the heating module according to the current temperature of the bottom of the electric pressure cooker. In summary, when the temperature of the bottom of the electric pressure cooker reaches the cooking set temperature and the total heating time reaches the cooking set time, the electric pressure cooker is considered to have met the preset cooking end conditions, further ensuring the reliability of the electric pressure cooker.

[0089] Please refer to Figure 3 , Figure 3 This is a schematic diagram of a protection system for abnormal cooking in an electric pressure cooker provided by the present invention. The control system includes:

[0090] The initial temperature determination unit 11 is used to determine the initial temperature of the food to be cooked in the electric pressure cooker after the electric pressure cooker is started.
