Description

Technical Field

[0001] This application belongs to the technical field of household appliances, and particularly relates to a control method, device, electric pressure cooker, and storage medium for an electric pressure cooker. Background Art

[0002] A temperature sensor is usually provided on the upper cover of the electric pressure cooker, and the temperature inside the pot can be detected through this temperature sensor. Since there is a certain distance between the upper cover and the bottom of the pot, when the water in the pot boils to generate steam, the temperature of the gas below the upper cover is still relatively low, and it takes a relatively long time for the temperature inside the pot to reach equilibrium. In this case or when the temperature sensor is blocked by the cover plate of the upper cover, the temperature sensor has a delay in sensing the temperature, that is, it cannot obtain the temperature inside the pot in time, and thus cannot obtain the pressure inside the pot according to the temperature inside the pot in time, resulting in a longer cooking time.

[0003] When the user uses the electric pressure cooker for fast cooking, in order to shorten the cooking time, it is necessary to reduce the response delay of the temperature inside the pot and reduce the time for detecting the temperature inside the pot. To achieve the above purpose, it is necessary to quickly discharge the gas with a relatively low temperature inside the pot. Therefore, how to quickly discharge the gas with a relatively low temperature inside the electric pressure cooker is an urgent problem to be solved. Summary of the Invention

[0048] To enable those skilled in the art to better understand this application, the application scenarios involved in this application will be briefly described first.

[0049] The upper cover of the electric pressure cooker is provided with a temperature detection device. When using this temperature detection device to detect the temperature inside the pot, since the gas temperature near the upper cover is still relatively low after the liquid in the pot boils and generates steam, the temperature detection device cannot accurately reflect the temperature inside the pot. In order to reduce the detection time of the temperature inside the pot and achieve the purpose of fast cooking, it is necessary to quickly discharge the gas with a relatively low temperature. The embodiments of this application perform exhaust control with different exhaust frequencies and heating powers according to the amount of liquid in the electric pressure cooker. Compared with exhausting with a fixed exhaust frequency and a fixed heating power, it can discharge the gas with a relatively low temperature more quickly, so that the temperature detection device can quickly and accurately detect the temperature inside the pot, reducing the time for detecting the temperature inside the pot and achieving the purpose of fast cooking.

[0050] Figure 1 Shows a schematic flow diagram of the control method of an electric pressure cooker in an embodiment. As Figure 1 shown, a control method of an electric pressure cooker is provided, and this method may include the following steps 101 to step 103.

[0051] Step 101, when the electric pressure cooker starts to build pressure, determine the amount of liquid in the electric pressure cooker.

[0052] It can be understood that the pressure build-up of an electric pressure cooker means that there is pressure inside the electric pressure cooker. When the electric pressure cooker builds up pressure, it is necessary to discharge the gas with a relatively low temperature inside the electric pressure cooker so that the temperature detection device can quickly and accurately detect the temperature inside the pot.

[0053] When the user starts the electric pressure cooker to start cooking, the electric pressure cooker starts to heat up. During the heating process, there are various ways to determine whether the electric pressure cooker builds up pressure.

[0054] In some embodiments, if the electric pressure cooker is provided with a pressure detection device, when the pressure detection device detects a pressure signal, it can be determined that the electric pressure cooker builds up pressure.

[0055] It can be understood that when there is pressure inside the electric pressure cooker, the float valve of the electric pressure cooker will be lifted. Therefore, the pressure detection device can be a device for detecting whether the float valve is lifted. If the float valve is lifted, the pressure detection device will detect a pressure signal and transmit it to the control unit of the electric pressure cooker so that the control unit can determine that the electric pressure cooker builds up pressure according to the pressure signal.

[0056] In other embodiments, if the electric pressure cooker is not provided with a pressure detection device, it can be determined that the electric pressure cooker builds up pressure when the temperature detected by the temperature detection device reaches a preset temperature.

[0057] Among them, the preset temperature can be set according to specific circumstances and can be about 100 °C. At this preset temperature, the liquid inside the electric pressure cooker boils to generate steam, thereby generating pressure inside the electric pressure cooker.

[0058] After the electric pressure cooker builds up pressure, there are various ways to determine the liquid volume inside the electric pressure cooker. This liquid volume can be the volume or mass of the liquid, and the embodiments of the present application do not limit this.

[0059] In some embodiments, the liquid volume can be determined according to the menu selected by the user.

[0060] It can be understood that the surface of the electric pressure cooker is usually designed with various menus, such as porridge, soup, chicken, beef and mutton, etc. Different menus correspond to different liquid volume requirements. In order to complete cooking, the user needs to first select a menu and then add the liquid with the corresponding liquid volume to the electric pressure cooker according to the menu prompt. Therefore, the liquid volume inside the electric pressure cooker can be determined according to the menu selected by the user.

[0061] In other embodiments, the heating duration can be determined according to the start time and pressure build-up time of the electric pressure cooker heating; the liquid volume inside the electric pressure cooker can be determined according to the heating duration.

[0062] During the implementation process, the time when the user clicks the "Start" button on the surface of the electric pressure cooker can be recorded and used as the heating start time. The time when it is determined that the electric pressure cooker starts to build pressure can be recorded and used as the pressure build-up time. Then, the difference between the pressure build-up time and the heating start time is used as the heating duration. The longer the heating duration, the more liquid there is; the shorter the heating duration, the less liquid there is.

[0063] It should be noted that in order to accurately determine the liquid volume in the electric pressure cooker, the corresponding relationship between the heating duration and the liquid volume can be pre-recorded through experiments to obtain the first relationship mapping table of the heating duration and the liquid volume. After the electric pressure cooker starts to build pressure, the first relationship mapping table is queried according to the heating duration of the electric pressure cooker, and the found liquid volume is determined as the liquid volume in the electric pressure cooker.

[0064] Step 102, determine the target exhaust frequency and the target heating power according to the liquid volume.

[0065] It should be noted that when the liquid volume is very small, a higher exhaust frequency can be used as the target exhaust frequency, and a higher heating power can be used as the target heating power to achieve the purpose of rapid exhaust; while when the liquid volume is relatively large, a lower exhaust frequency can be used as the target exhaust frequency, and a lower heating power can be used as the target heating power to avoid liquid overflow.

[0066] Figure 2 shows Figure 1 a detailed schematic diagram of step 102 in Figure 2 As shown, step 102 may include:

[0067] Step 201, when the liquid volume is less than the preset threshold, determine the first exhaust frequency as the target exhaust frequency and determine the first heating power as the target heating power;

[0068] Step 202, when the liquid volume is greater than or equal to the preset threshold, determine the second exhaust frequency as the target exhaust frequency and determine the second heating power as the target heating power, where the first exhaust frequency is greater than the second exhaust frequency, the first heating power is greater than or equal to the current heating power of the electric pressure cooker, and the second heating power is less than the current heating power.

[0069] Among them, the preset threshold can be determined according to the volume of the electric pressure cooker. For example, for an electric pressure cooker with a volume of 4L, the preset threshold can be 200mL. Of course, the preset threshold can also be determined by other means, and the embodiments of the present application do not limit this.

[0070] During the implementation process, when the liquid volume is less than the preset threshold, the first heating power can be maintained at the current heating power or higher than the current heating power. For example, it can be the rated power. Usually, in order to achieve rapid pressure rise, the electric pressure cooker will heat at the rated power, that is, the current heating power of the electric pressure cooker is the rated power. In this case, the first heating power can just maintain the current heating power.

[0071] When the user cooks easily cooked ingredients, generally very little liquid is added, such as 50 mL. In this case, adopting a higher first exhaust frequency can increase the exhaust time, accelerate the discharge of the gas with a lower temperature, shorten the cooking time. At the same time, adopting a higher first heating power can further shorten the cooking time.

[0072] When the user adds a large amount of liquid, such as half a pot or a full pot, adopt a lower second exhaust frequency, and reduce the current heating frequency to the second heating frequency. The float valve drops, and the gas with a lower temperature will be slowly discharged, which can effectively avoid liquid overflow.

[0073] Step 103, control the electric pressure cooker to operate according to the target exhaust frequency and the target heating power.

[0074] During the implementation process, the exhaust valve of the electric pressure cooker can be controlled to open according to the target exhaust frequency, and the heating device of the electric pressure cooker can be controlled to heat according to the target heating power, so that the electric pressure cooker discharges the gas with a lower temperature.

[0075] In some embodiments, the first exhaust period can be determined according to the first exhaust frequency; the first exhaust duration can be determined according to the first exhaust period and the first preset ratio; control the electric pressure cooker to operate according to the first exhaust duration and the first heating power, where the first preset ratio is between 10% and 40%.

[0076] Among them, the reciprocal of the first exhaust frequency can be used as the first exhaust period. Taking the first exhaust frequency of 0.25 Hz as an example, the first exhaust period is 4 s, and the first exhaust duration is between 0.4 s and 1.6 s. Assuming the first exhaust duration is 1 s, it means that within an exhaust period of 4 s, 1 s is used for exhaust and 3 s is not for exhaust.

[0077] After determining the first exhaust duration, control the opening duration of the exhaust valve within an exhaust period to be the first exhaust duration, control the exhaust valve to close at other times within this exhaust period, and control the heating device of the electric pressure cooker to heat at the first heating power within this exhaust period.

[0078] It should be noted that by setting the first preset ratio between 10% and 40%, the proportion of the exhaust duration can be ensured to be moderate, which not only avoids the failure to achieve the purpose of rapid exhaust due to too short exhaust duration, but also avoids the high-temperature gas generated from being discharged before it has time to boost pressure, resulting in the failure to build pressure.

[0079] In some embodiments, the second exhaust period can be determined according to the second exhaust frequency; the second exhaust duration can be determined according to the second exhaust period and the second preset ratio; the electric pressure cooker is controlled to operate according to the second exhaust duration and the second heating power, wherein the second preset ratio is less than 10%.

[0080] Among them, the reciprocal of the second exhaust frequency can be used as the second exhaust period. Taking the second exhaust frequency of 0.1 Hz as an example, the second exhaust period is 10 s, and the second exhaust duration is less than 1 s. Assuming the second exhaust duration is 0.5 s, it means that within one exhaust period of 10 s, 0.5 s is used for exhaust and 9.5 s is not for exhaust.

[0081] After determining the second exhaust duration, the opening duration of the exhaust valve is controlled to be the second exhaust duration within one exhaust period, the exhaust valve is controlled to be closed at other times within this exhaust period, and the heating device of the electric pressure cooker is controlled to heat at the second heating power within this exhaust period.

[0082] It should be noted that by setting the second preset ratio below 10%, the exhaust duration can be ensured to be short, avoiding the liquid in the electric pressure cooker from overflowing.

[0083] During the exhaust process of the electric pressure cooker, it is necessary to monitor the pressure inside the electric pressure cooker in real time to determine whether to control the electric pressure cooker to stop exhausting according to the pressure inside the electric pressure cooker.

[0084] In some embodiments, the pressure inside the electric pressure cooker can be determined according to the temperature detected by the temperature detection device; when the pressure inside the electric pressure cooker reaches the preset pressure, the electric pressure cooker is controlled to stop exhausting.

[0085] In the implementation process, the corresponding relationship between the temperature and pressure of the electric pressure cooker can be recorded in advance through experiments to obtain the second relationship mapping table of temperature and pressure. After the electric pressure cooker exhausts, the second relationship mapping table is queried according to the temperature detected by the temperature detection device, and the found pressure is determined as the pressure inside the electric pressure cooker.

[0086] It can be understood that when the liquid volume inside the electric pressure cooker is small, after the electric pressure cooker exhausts, if the pressure inside the electric pressure cooker reaches the preset pressure, the electric pressure cooker is controlled to stop exhausting and continue the subsequent cooking.

[0087] When there is a relatively large amount of liquid in the electric pressure cooker, after the electric pressure cooker exhausts, it can be determined whether to control the electric pressure cooker to stop exhausting according to whether multiple parameters meet preset conditions.

[0088] The parameter can be the number of exhausts. When the number of exhausts reaches a preset number (for example, 10 to 20 times), control the electric pressure cooker to stop exhausting; the parameter can also be the pressure inside the electric pressure cooker. When the pressure inside the electric pressure cooker reaches a preset pressure, control the electric pressure cooker to stop exhausting; the parameter can also be the pressure rising state. When the pressure rising state is that the electric pressure cooker rises in pressure again, control the electric pressure cooker to stop exhausting.

[0089] In the embodiment of the present application, when the electric pressure cooker rises in pressure, the amount of liquid inside the electric pressure cooker is determined; the target exhaust frequency and the target heating power are determined according to the amount of liquid; the electric pressure cooker is controlled to operate according to the target exhaust frequency and the target heating power. The technical solution provided by the present application performs exhaust control using different exhaust frequencies and heating powers according to the amount of liquid, can quickly discharge the gas with a lower temperature inside the electric pressure cooker, thereby quickly and accurately detecting the temperature inside the pot, reducing the time for detecting the temperature inside the pot, and achieving the purpose of quick cooking.

[0090] Figure 3 The flowchart of the control method of the electric pressure cooker in another embodiment is shown. As Figure 3 shown, the control method of the electric pressure cooker may include the following steps:

[0091] Step 301, when the temperature detected by the temperature detection device reaches the preset temperature, or when the pressure detection device detects a pressure signal, determine that the electric pressure cooker rises in pressure;

[0092] Step 302, determine the heating duration according to the heating start time and the pressure rising time of the electric pressure cooker, and determine the amount of liquid inside the electric pressure cooker according to the heating duration;

[0093] Step 303, when the amount of liquid is less than the preset threshold, determine the first exhaust frequency as the target exhaust frequency, and determine the first heating power as the target heating power;

[0094] Step 304, determine the first exhaust period according to the first exhaust frequency, determine the first exhaust duration according to the first exhaust period and the first preset ratio, and control the electric pressure cooker to operate according to the first exhaust duration and the first heating power, where the first preset ratio is between 10% and 40%;

[0095] Step 305, when the liquid volume is greater than or equal to a preset threshold, determine the second exhaust frequency as the target exhaust frequency and determine the second heating power as the target heating power, where the first exhaust frequency is greater than the second exhaust frequency, the first heating power is greater than or equal to the current heating power of the electric pressure cooker, and the second heating power is less than the current heating power;

[0096] Step 306, determine the second exhaust period according to the second exhaust frequency, determine the second exhaust duration according to the second exhaust period and the second preset ratio, and control the electric pressure cooker to operate according to the second exhaust duration and the second heating power, where the second preset ratio is less than 10%;

[0097] Step 307, determine the pressure inside the electric pressure cooker according to the temperature detected by the temperature detection device, and when the pressure inside the electric pressure cooker reaches the preset pressure, control the electric pressure cooker to stop exhausting.

[0098] In the embodiment of the present application, by determining the liquid volume according to the heating duration, the calculation accuracy of the liquid volume is improved. By exhausting with a higher exhaust frequency and a higher heating power when the liquid volume is small, the cooking time is effectively shortened; by exhausting with a lower exhaust frequency and a lower heating power when the liquid volume is large, the liquid overflow inside the electric pressure cooker is avoided, meeting the user's needs for convenient and fast cooking, and enhancing the use value and competitiveness of the product.
