[0030] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] The cooking method and the cooking appliance for a cooking appliance according to an embodiment of the present invention will be described in detail below with reference to the drawings.

[0032] According to the cooking method for a cooking appliance according to the first aspect embodiment of the present invention, with reference to Figure 1 as shown, the cooking appliance 10 includes a steam generating device 1 and a cooking pot 2. The steam generating device 1 is used to heat a liquid to form steam, and the steam generating device 1 is used to introduce the steam into the cooking pot 2. The cooking pot 2 has a cooking cavity suitable for containing food materials. After the steam generated by heating the liquid by the steam generating device 1 enters the cooking pot 2, it can heat the food materials in the cooking cavity to realize steaming of the food materials. Among them, the liquid heated by the steam generating device 1 can be water or a mixed liquid of water and seasonings.

[0033] It can be understood that parameters such as the liquid inflow rate and heating power of the steam generating device can be adjusted according to the required steam temperature so that the steam generating device generates steam at the corresponding temperature.

[0034] Figure 2 FIG. is a flowchart of a cooking method for a cooking appliance according to an embodiment of the present invention. Refer to Figure 2 As shown, the cooking method for a cooking appliance includes:

[0035] S1, in the first cooking stage, control the steam generating device to operate to form steam at a first preset temperature in the steam generating device.

[0036] Among them, the first cooking stage can be the cooking stage when the cooking appliance initially heats the ingredients in the cooking pot. During this process, the steam mainly acts on the surface of the ingredients to heat up the surface of the ingredients.

[0037] S2, in the second cooking stage, control the steam generating device to operate to form steam at a second preset temperature in the steam generating device.

[0038] Among them, the second cooking stage is the cooking stage after the first cooking stage. During this process, the steam is mainly used to continuously heat or keep warm the whole ingredients to cook the ingredients.

[0039] Refer to Figure 3 As shown, the first cooking stage is before the second cooking stage, and the first preset temperature is greater than the second preset temperature. In the first cooking stage, the steam at the higher first preset temperature can quickly act on the surface of the ingredients, accelerating the ripening of the surface of the ingredients, improving the water-locking effect on the surface of the ingredients, reducing the loss of moisture and nutrients in the ingredients, and improving the cooking effect. In the second cooking stage, the steam at the lower second preset temperature can keep the temperature of the ingredients, and cook the ingredients with lower energy consumption. At the same time, since the first cooking stage is before the second cooking stage, after the first cooking stage is completed, the surface of the ingredients is basically cooked and has a good water-locking effect. Therefore, when using the steam at the lower second preset temperature to cook the ingredients in the second cooking stage, the ingredients will not lose too much moisture and nutrients to ensure the cooking effect.

[0040] According to the cooking method of the cooking appliance of the embodiment of the present invention, control the steam temperature of the steam generating device in the first cooking stage to be greater than that in the second cooking stage, so as to improve the water-locking effect on the surface of the ingredients in the first cooking stage, reduce the loss of moisture and nutrients in the ingredients, which is beneficial to improving the cooking effect of the cooking appliance, enhancing the use experience of the cooking appliance and the product competitiveness.

[0041] In some embodiments of the present invention, the cooking method further includes:

[0042] S3. Control the steam generating device to operate in the third cooking stage to form steam at a third preset temperature within the steam generating device.

[0043] Among them, the third cooking stage comes after the second cooking stage, and the third preset temperature is greater than the second preset temperature. That is to say, the third cooking stage is the cooking stage after the second cooking stage, that is, the cooking stage of the cooking appliance for the ingredients in the cooking pot before the end of cooking. During this process, the steam is mainly used to promote the further ripening of the ingredients and heat the condensed water in the cooking pot to evaporate the condensed water, so as to reduce the amount of condensed water on the inner wall of the cooking pot.

[0044] It can be understood that both the first preset temperature and the third preset temperature are greater than the second preset temperature. Referring to Figure 3 As shown, in the first cooking stage, the steam at the relatively high first preset temperature can quickly act on the surface of the ingredients, accelerate the ripening of the surface of the ingredients, improve the water-locking effect on the surface of the ingredients, reduce the loss of water and nutrients in the ingredients, and improve the cooking effect. In the second cooking stage, the steam at the relatively low second preset temperature can keep the temperature of the ingredients and achieve the ripening of the ingredients with lower energy consumption. In the third cooking stage, the steam at the relatively high third preset temperature can heat the condensed water in the cooking pot while heating the ingredients, so that the condensed water evaporates and is discharged from the cooking pot through the exhaust hole in the cooking pot, reducing the amount of condensed water on the inner wall of the cooking pot and reducing the risk of condensed water droplets falling onto the surface of the ingredients.

[0045] In some embodiments of the present invention, the duration of the first cooking stage is less than the duration of the second cooking stage to prevent the surface of the ingredients from becoming hard due to the relatively long first cooking stage. The duration of the third cooking stage is less than the duration of the first cooking stage to prevent the surface of the ingredients from becoming hard due to the relatively long third cooking stage.

[0046] In some embodiments of the present invention, the cooking method further includes: controlling the steam temperature within the steam generating device by adjusting the flow rate of the liquid flowing into the steam generating device and / or adjusting the heating power of the steam generating device, so as to form steam at the first preset temperature, the second preset temperature and the third preset temperature within the steam generating device as needed.

[0047] In some embodiments, the steam temperature in the steam generating device is controlled by adjusting the flow rate of the liquid flowing into the steam generating device. Among them, the heating power of the evaporation device can be kept constant. In the second cooking stage, the steam generating device can heat the liquid flowing into it to form steam at a second preset temperature, and the second preset temperature can be the boiling point temperature of water (for example, the second preset temperature is 100 °C). Compared with the second cooking stage, in the first cooking stage, the flow rate of the liquid flowing into the steam generating device can be reduced (for example, reduced from 5 g / s to 2 g / s), and the steam generating device has a certain degree of dry burning to heat the steam, so as to form steam at a first preset temperature (for example, the first preset temperature is 120 °C). The control principle of the third cooking stage is the same as that of the first cooking stage.

[0048] In other embodiments, the steam temperature in the steam generating device is controlled by adjusting the heating power of the steam generating device. Among them, the flow rate of the liquid flowing into the steam generating device can be kept constant. In the second cooking stage, the steam generating device can heat the liquid flowing into it to form steam at a second preset temperature, and the second preset temperature can be the boiling point temperature of water (for example, the second preset temperature is 100 °C). Compared with the second cooking stage, in the first cooking stage, the heating power of the steam generating device can be increased (for example, increased from 1500 w to 2000 w), and the steam generating device has a certain degree of dry burning to heat the steam, so as to form steam at a first preset temperature (for example, the first preset temperature is 120 °C). The control principle of the third cooking stage is the same as that of the first cooking stage.

[0049] In still other embodiments, the steam temperature in the steam generating device is controlled by adjusting the flow rate of the liquid flowing into the steam generating device and adjusting the heating power of the steam generating device. In the second cooking stage, the steam generating device can heat the liquid flowing into it to form steam at a second preset temperature, and the second preset temperature can be the boiling point temperature of water (for example, the second preset temperature is 100 °C). Compared with the second cooking stage, in the first cooking stage, the flow rate of the liquid flowing into the steam generating device can be reduced (for example, reduced from 5 g / s to 4 g / s), and at the same time, the heating power of the steam generating device is increased (for example, increased from 1500 w to 1800 w). The steam generating device has a certain degree of dry burning to heat the steam, so as to form steam at a first preset temperature (for example, the first preset temperature is 120 °C). The control principle of the third cooking stage is the same as that of the first cooking stage.

[0050] It should be noted that only one heating element can be provided in the steam generating device for heating the liquid and the steam simultaneously. Multiple heating elements can also be provided in the steam generating device, and at least one of the multiple heating elements is used to heat the steam to achieve the adjustment of the steam temperature.

[0051] In some embodiments of the present invention, a liquid pump is provided at the liquid inlet of the steam generating device, and the liquid flow rate flowing into the steam generating device can be adjusted by controlling the liquid pump. Among them, the liquid pump can be an electronic diaphragm pump.

[0052] In some embodiments of the present invention, the first cooking stage controls the steam generating device to operate to form steam at a first preset temperature in the steam generating device, including: controlling the liquid to flow into the steam generating device at a first set flow rate to form steam at the first preset temperature.

[0053] Among them, the first set flow rate can be 2 g / s. The steam generating device has a certain degree of dry burning to heat the steam, so as to form steam at the first preset temperature. The first preset temperature can be 120 °C.

[0054] The second cooking stage controls the steam generating device to operate to form steam at a second preset temperature in the steam generating device, including: controlling the liquid to flow into the steam generating device at a second set flow rate to form steam at the second preset temperature, and the second set flow rate is greater than the first set flow rate.

[0055] Among them, the second set flow rate can be 5 g / s. The steam generating device can heat the liquid flowing into it to form steam at the second preset temperature. The second preset temperature can be the boiling point temperature of water, and the second preset temperature can be 100 °C.

[0056] The third cooking stage controls the steam generating device to operate to form steam at a third preset temperature in the steam generating device, including: controlling the liquid to flow into the steam generating device at a third set flow rate to form steam at the third preset temperature, and the third set flow rate is less than or equal to the first set flow rate.

[0057] Among them, the third set flow rate can be 2 g / s. The steam generating device has a certain degree of dry burning to heat the steam, so as to form steam at the third preset temperature. The first preset temperature can be 120 °C.

[0058] Thus, it is possible to control the steam temperature in the steam generating device by adjusting the flow rate of the liquid flowing into the steam generating device.

[0059] In some embodiments of the present invention, the first set flow rate is Q1, the second set flow rate is Q2, and the third set flow rate is Q3, satisfying the relational expression: 2 g / s ≤ Q1 ≤ 6 g / s, 5 g / s ≤ Q2 ≤ 8 g / s, 2 g / s ≤ Q3 ≤ 6 g / s. Among them, the second set flow rate Q2 can be determined according to the rated heating power of the steam generating device. Under the rated heating power of the steam generating device, the liquid inflow rate that keeps the liquid in the steam generating device in a boiling state is the second set flow rate Q2. The second set flow rate Q2 can be 5 g / s, 6 g / s, 7 g / s, or 8 g / s. When the second set flow rate Q2 is greater than the first set flow rate Q1, the first set flow rate Q1 can be 2 g / s, 3 g / s, 4 g / s, 5 g / s, or 6 g / s. When the third set flow rate Q3 is less than or equal to the first set flow rate Q1, the first set flow rate Q1 can be 2 g / s, 3 g / s, 4 g / s, 5 g / s, or 6 g / s.

[0060] For example, the first set flow rate is 2 g / s, the second set flow rate Q2 is 5 g / s, and the third set flow rate is 2 g / s. For another example, the first set flow rate is 5 g / s, the second set flow rate Q2 is 6 g / s, and the third set flow rate is 4 g / s. For still another example, the first set flow rate is 6 g / s, the second set flow rate Q2 is 8 g / s, and the third set flow rate is 6 g / s.

[0061] In some embodiments of the present invention, the steam generating device includes a first heating element, a second heating element, a steam generator, and a steam conduit. The steam conduit connects the steam generator and the cooking pot. The first heating element is used to heat the liquid in the steam generator, and the second heating element is used to heat the steam in the steam conduit to achieve separate heating of the liquid and the steam, so as to facilitate precise control of the steam temperature.

[0062] It can be understood that the heating power of the steam generating device is the sum of the power of the first heating element and the power of the second heating element. During the cooking process, the first heating element can keep working to heat the liquid into steam, and the heating power of the steam generating device can be controlled by controlling whether the second heating element works.

[0063] The first cooking stage controls the steam generating device to work to form steam at a first preset temperature in the steam generating device, including: controlling the first heating element and the second heating element to work to form steam at a first preset temperature. That is to say, when the first heating element works, it can heat the liquid in the steam generator to boiling to form steam. When the steam flows through the steam conduit to the cooking pot, the second heating element works and heats the steam in the steam conduit to the first preset temperature to achieve separate heating of the liquid and the steam. At the same time, the temperature of the steam can be precisely controlled by controlling the power of the second heating element.

[0064] It should be noted that the first heating element heats the liquid in the steam generator to form steam at a second preset temperature, which can be the boiling point temperature of water (e.g., 100 °C). The steam at the second preset temperature is heated by the second heating element in the steam conduit to reach the first preset temperature (e.g., 120 °C). The steam at the higher first preset temperature can act quickly on the surface of the food material, accelerating the ripening of the food material surface and enhancing the water-locking effect on the food material surface.

[0065] In some embodiments of the present invention, controlling the steam generating device to operate in the second cooking stage to form steam at a second preset temperature in the steam generating device includes: controlling the first heating element to operate to form steam at the second preset temperature. That is to say, when forming steam at the second preset temperature in the steam generating device, the first heating element operates and the second heating element may not operate. The steam at the second preset temperature formed by the first heating element heating the liquid may not require additional heating, so as to reduce the energy consumption of the cooking appliance.

[0066] In some other embodiments of the present invention, controlling the steam generating device to operate in the second cooking stage to form steam at a second preset temperature in the steam generating device includes: determining the altitude at which the cooking appliance is located. When the altitude is less than or equal to a preset altitude threshold, controlling the first heating element to operate to form steam at the second preset temperature. When the altitude is greater than the preset altitude threshold, controlling the first heating element and the second heating element to operate to form steam at the second preset temperature. Among them, the preset altitude threshold can be 1500 m. When the cooking appliance is used at an altitude less than or equal to the preset altitude threshold, the first heating element can heat the liquid to steam when it operates, and the steam temperature is the boiling point temperature of water at the current altitude, which is the second preset temperature. When the cooking appliance is used at an altitude greater than the preset altitude threshold, to avoid the low boiling point temperature of water at high altitudes resulting in difficult steaming of food, the first heating element can be controlled to operate to heat the liquid to steam. When the steam flows through the steam conduit to the cooking pot, the second heating element operates and heats the steam in the steam conduit to the second preset temperature, so as to ensure that steam at the second preset temperature is formed in the steam generating device by the combined operation of the first heating element and the second heating element at high altitudes.

[0067] In some embodiments of the present invention, controlling the steam generating device to operate in the third cooking stage to form steam at a third preset temperature in the steam generating device includes: controlling the first heating element and the second heating element to operate to form steam at the third preset temperature. That is to say, when the first heating element operates, it can heat the liquid in the steam generator to boiling to form steam. When the steam flows through the steam conduit to the cooking pot, the second heating element operates and heats the steam in the steam conduit to the third preset temperature, so as to achieve separate heating of the liquid and the steam. At the same time, the temperature of the steam can be precisely controlled by controlling the power of the second heating element.

[0068] In some embodiments of the present invention, the first preset temperature is T1, the second preset temperature is T2, and the third preset temperature is T3, satisfying the relational expression: T1≥120°C, 95°C≤T2≤110°C, T3≥120°C, so as to improve the water-locking effect on the surface of the food ingredients in the first cooking stage, reduce the loss of water and nutrients in the food ingredients, ensure the ripening of the food ingredients in the second cooking stage, and reduce the amount of condensed water on the inner wall of the cooking pot in the third cooking stage.

[0069] It can be understood that in the first cooking stage, if the first preset temperature T1 < 120°C, the heating rate of the surface of the food ingredients is slow, and the water and nutrients in the food ingredients will be lost through the surface of the food ingredients during the steaming process. In the embodiments of the present invention, the first preset temperature T1≥120°C, and the first preset temperature T1 can be 120°, 125° or 130°, etc., so as to improve the water-locking effect on the surface of the food ingredients in the first cooking stage and reduce the loss of water and nutrients in the food ingredients.

[0070] In the second cooking stage, the steam is mainly used to continuously heat or keep warm the whole food ingredients. If the second preset temperature T2 < 95°C, the temperature of the food ingredients is relatively low during the steaming process, and it is difficult to steam the food ingredients thoroughly. If the second preset temperature T2 > 110°C, the internal and external heating of the food ingredients during the steaming process is uneven, which affects the cooking effect of the food ingredients, and the energy consumption of the cooking appliance is also relatively high. In the embodiments of the present invention, 95°C≤T2≤110°C, and the second preset temperature T2 can be 95°C, 100°C, 105°C or 110°C, so as to take into account the energy consumption of the cooking appliance and the cooking effect of the food ingredients while ensuring the ripening of the food ingredients.

[0071] In the third cooking stage, the steam is mainly used to promote the further ripening of the food ingredients and heat the condensed water in the cooking pot. If the third preset temperature T3 < 120°C, a large amount of condensed water in the cooking pot will remain on the inner wall of the cooking pot, and the condensed water is likely to drip onto the surface of the food ingredients, affecting the cooking effect. In the embodiments of the present invention, the third preset temperature T3≥120°C, and the third preset temperature T3 can be 120°, 125° or 130°, etc. In the third cooking stage, while the steam heats the food ingredients, it can also heat the condensed water in the cooking pot, so that the condensed water evaporates and is discharged from the cooking pot through the exhaust hole in the cooking pot, reducing the risk of the condensed water dripping onto the surface of the food ingredients and having a good moisture-removing effect.

[0072] According to the computer-readable storage medium of the second aspect embodiment of the present invention, a control program of a cooking appliance is stored thereon, and when the control program is executed by a processor, the cooking method of the above embodiment is implemented.

[0073] When the control program stored in the computer-readable storage medium according to an embodiment of the present invention is executed by a processor, the steam generation device is controlled such that the steam temperature in the first cooking stage is higher than that in the second cooking stage, so as to improve the water-locking effect on the surface of the food material in the first cooking stage, reduce the loss of moisture and nutrients in the food material, thereby facilitating the improvement of the cooking effect of the cooking appliance, and enhancing the use experience of the cooking appliance and the product competitiveness.

[0074] The cooking appliance according to the third aspect embodiment of the present invention includes a memory, a processor, and a control program of the cooking appliance stored in the memory and executable on the processor. When the processor executes the control program of the cooking appliance, the cooking method of the above embodiment is implemented.

[0075] When the processor of the cooking appliance according to an embodiment of the present invention executes the control program of the cooking appliance, the steam generation device is controlled such that the steam temperature in the first cooking stage is higher than that in the second cooking stage, so as to improve the water-locking effect on the surface of the food material in the first cooking stage, reduce the loss of moisture and nutrients in the food material, thereby facilitating the improvement of the cooking effect of the cooking appliance, and enhancing the use experience of the cooking appliance and the product competitiveness.

[0076] The cooking appliance 10 according to the fourth aspect embodiment of the present invention, refer to Figure 1 As shown, the cooking appliance 10 includes: a steam generation device 1, a cooking pot 2, and a control module. The steam generation device 1 is used to heat a liquid to form steam, and the steam generation device 1 is used to introduce the steam into the cooking pot 2.
