The cooking appliance 100 and the control method of the cooking appliance 100 according to the embodiment of the present invention are described below with reference to the accompanying drawings. The cooking appliance 100 according to the embodiment of the present invention operates using the control method of the cooking appliance 100 according to the embodiment of the present invention.

Referring to fig. 1, the cooking appliance 100 may include: a pot body assembly 10 and a pot cover assembly.

Specifically, as shown in fig. 1 and 3, pan body assembly 10 has a cooking cavity 101 therein, and pan body assembly 10 may be provided with a first heating assembly 12, and first heating assembly 12 may heat cooking cavity 101 of pan body assembly 10. The pan cover assembly can be covered on the pan body assembly 10.

The cooking appliance 100 has a first cooking mode and a second cooking mode. In the first cooking mode, the first heating assembly 12 heats the cooking cavity 101, and when some food is cooked, the food can be steamed, braised, boiled, etc. by the first heating assembly 12.

As shown in fig. 2 to 5, the lid assembly may include a lid body 31, a second heating assembly 33 and a fan 34, the second heating assembly 33 and the fan 34 are disposed on the lid body 31, and the second heating assembly 33 may also heat the cooking cavity 101. In the second cooking mode, the second heating assembly 33 operates to heat air, and the fan 34 may blow a hot air flow heated by the second heating assembly 33 to the cooking chamber 101. Due to the high temperature hot air flow, when cooking some foods, the foods may be fried, fried or air-fried.

In the present invention, when the cooking appliance 100 receives a cooking instruction, the first heating assembly 12 may be controlled to heat the cooking cavity 101 to perform the first cooking mode. After the first cooking mode is finished, the second heating assembly 33 and the fan 34 are controlled to work, so that the hot air flow heated by the second heating assembly 33 is blown to the cooking cavity 101 by the fan 34, so that the cooking appliance 100 performs the second cooking mode.

Therefore, stewing and then frying cooking of food can be realized, and the cooking appliance 100 can directly realize one-pot cooking of the food in the cooking cavity 101 through two seamless connection cooking modes. By simmering in the first cooking mode, the food can be cooked quickly, and especially in the embodiment with pressure, the cooking time can be saved. When the food is cooked or is cooked quickly, the food is fried by switching to the second cooking mode, and the two different cooking modes are matched to well lock the moisture of the food, so that the food has the mouthfeel that the inside is tender and the outside is crisp. The problem that when the food is fried and heated in the whole process, the hot air flow takes away more water of the food to cause the cooked food to be dry is solved, and the problem that when the food is braised and cooked in the whole process and heated, the cooked food is not crisp enough on the surface and poor in taste is also solved.

In the embodiment where first heating assembly 12 is disposed on pan assembly 10, optionally, in the second cooking mode, first heating assembly 12 may stop heating or may use low power (typically less than 500W) to heat cooking chamber 101.

For example, in the embodiment where the first heating assembly 12 heats food from the lower side of the food and the second heating assembly 33 heats food from the upper side of the food, the first heating assembly 12 and the second heating assembly 33 cooperate to achieve uniform heating of the food from the upper side to the lower side, and the food is cooked to the inside from the upper surface and the lower surface, which is beneficial to improving the cooking uniformity and efficiency of the food.

According to the control method of the cooking appliance 100 of the embodiment of the invention, the cooking appliance 100 is controlled to stew and cook food in the first cooking mode to quickly cook the food, the food is baked in the second cooking mode to crisp the surface of the food, and the cooking appliance 100 is controlled to execute the second cooking mode after the first cooking mode is executed, so that the cooking modes of stewing before frying and drying after seamless connection of the two cooking modes can be realized, the cooking time is effectively shortened, the moisture of the food is locked, and the food has good mouthfeel of tender inside and crisp outside.

According to some embodiments of the present invention, as shown in fig. 1, the lid assembly may include a first lid assembly 20 and a second lid assembly 30, wherein the cooking appliance 100 is in the first cooking mode when the first lid assembly 20 covers the pre-lid assembly 10 and the first heating assembly 12 is operated, and the cooking appliance 100 is in the second cooking mode when the second lid assembly 30 covers the lid assembly 10 and the second heating assembly 33 and the blower 34 are operated. The cooking mode can be switched by replacing the first pot cover assembly 20 or the second pot cover assembly 30 matched with the pot body assembly 10, and the use is more convenient.

Further, after the first cooking mode is finished and before the second heating assembly 33 is controlled to heat, it may be detected whether the second lid assembly 30 is covered on the pot assembly 10, the cooking appliance 100 performs the second cooking mode when it is detected that the second lid assembly 30 is covered on the pot assembly, and the second heating assembly 33 does not heat when it is detected that the second lid assembly 30 is not covered on the pot assembly. Therefore, when the second pot cover assembly 30 is not covered on the pot body assembly 10, the second heating assembly 33 can be prevented from heating to scald users or bake out equipment near the cooking utensil 100, and the use is safer.

Alternatively, in some embodiments, pan body assembly 10 may alternatively be removably coupled to first pan cover assembly 20 and second pan cover assembly 30. That is, in the first cooking mode, the pot body assembly 10 may be connected with the first lid assembly 20, and the second lid assembly 30 is separated from the pot body assembly 10. In the second cooking mode, the pot body assembly 10 may be connected with the second lid assembly 30, and the first lid assembly 20 is separated from the pot body assembly 10.

Therefore, when one of the first and

second lid assemblies

20 and 30 is covered on the pot body assembly 10, the other of the first and

second lid assemblies

20 and 30 has no influence on the use of the cooking device 100, and the cooking device 100 has a simple structure and a lower overall height.

It should be noted that, according to actual needs, the cooking appliance 100 may further include a third lid assembly, a fourth lid assembly or more lid assemblies, so that the cooking appliance 100 may have a third cooking mode, a fourth cooking mode and more cooking modes under the control of the control method, and only the requirement that the second cooking mode is executed after the first cooking mode under the control of the control method needs to be satisfied.

In addition, after the first cooking mode is finished, the control method according to some embodiments of the present invention may control the cooking appliance 100 to send a prompt message to remind the user to replace the first lid assembly 20 with the second lid assembly 30, so as to prevent the user from forgetting to replace the first lid assembly and the second lid assembly, which may cause the cooking to be unable to be performed normally.

Alternatively, in the present invention, the prompt message sent by the cooking appliance 100 may be a display message (e.g., a display screen display message, a light prompt message), a voice message (e.g., a voice broadcast, a music prompt tone, etc.), or the like, or may include a combination of at least two of the above prompt messages.

According to some embodiments of the present invention, as shown in fig. 2 and 4, the pot body assembly 10 may have a first coupler 11, the second pot cover assembly 30 may have a second coupler 32, and when the second pot cover assembly 30 is covered on the pot body assembly 10, the first coupler 11 and the second coupler 32 may be coupled, so that the second pot cover assembly 30 and the pot body assembly 10 may be coupled, and the second pot cover assembly 30 may be powered through the pot body assembly 10. The coupling structure of the first coupler 11 and the second coupler 32 can be disassembled, and is convenient to disassemble and assemble, the second cover assembly 30 is more stable in electric connection with the pot body assembly 10, the second heating assembly 33 works more stably, and the second cover assembly 30 is more convenient to disassemble and assemble with the pot body assembly 10.

In some embodiments of the present invention, as shown in fig. 3, pan body assembly 10 may comprise: housing 13, pot 14, and control system 15. Pot 14 may be disposed within housing 13 and first heating assembly 12 may be disposed within pot 14 such that first heating assembly 12 may heat cooking chamber 101. Alternatively, first heating assembly 12 may be disposed at least one of the underside of pan body 14 and the outside of the outer peripheral surface.

In addition, as shown in fig. 3, the control system 15 may be connected to the housing 13, and the control system 15 may control the first heating assembly 12 and the second heating assembly 33 to operate, so that the first heating assembly 12 and the second heating assembly 33 are controlled by the same control system 15, which may simplify the structure of the second lid assembly 30, simplify the structure of the cooking appliance 100, and facilitate the cooking appliance 100 to switch between the first cooking mode and the second cooking mode under the control of the control method. In addition, the second heating assembly 33 can realize signal connection through the first coupler 11 and the second coupler 32, and the electric transmission and signal transmission structure of the second heating assembly 33 are integrally arranged, so that the structure of the cooking appliance 100 is further simplified, and the second cover assembly 30 and the pot body assembly 10 are more convenient to disassemble and assemble.

According to some embodiments of the present invention, as shown in fig. 3 and 5, the cooking appliance 100 may further include: a first temperature sensor 40 and a second temperature sensor 41, wherein the first temperature sensor 40 is disposed on the pot body assembly 10, the second temperature sensor 41 is disposed on the pot cover assembly, and the first temperature sensor 40 and the second temperature sensor 41 can detect the temperature in the cooking cavity 101. The control method can control the cooking appliance 100, so that the cooking appliance 100 controls the first heating assembly 12 to work according to the temperature detection result of the first temperature sensor 40 when the cooking appliance 100 is in the first cooking mode, and the heating temperature, the switching state and the like of the first heating assembly 12 are more in accordance with the use requirements. The control method can also control the cooking appliance 100, so that the cooking appliance 100 controls the second heating assembly 33 to work according to the temperature detection result of the second temperature sensor 41 when the cooking appliance is in the second cooking mode, and the heating temperature, the switching state and the like of the second heating assembly 33 are more in accordance with the use requirements.

Further, as shown in fig. 3, a first heating assembly 12 may be provided at the bottom of the pot assembly 10 to heat the cooking chamber 101 from the lower side. The first temperature sensor 40 may detect the temperature of the lower portion of the cooking cavity 101, and control the operation of the first heating assembly 12 according to the temperature detection result of the lower portion of the cooking cavity 101, the temperature detection result of the first temperature sensor 40 is more accurate, and the heating temperature of the first heating assembly 12 is more accurately controlled. The second temperature sensor 41 may be connected to the lid body 31 of the second lid assembly 30, and the second temperature sensor 41 may detect the temperature of the upper portion of the cooking chamber 101, and control the operation of the second heating assembly 33 according to the temperature detection result of the upper portion of the cooking chamber 101, the temperature detection result of the second temperature sensor 41 being more accurate, and the heating temperature control of the second heating assembly 33 being more accurate.

Still further, as shown in fig. 3 and 5, the second heating assembly 33 may include a heating tube extending horizontally and spirally, and the second temperature sensor 41 may be disposed at the center of the heating tube. The second temperature sensor 41 is closer to the heating pipe, the temperature detection result is more accurate, and the structure is more compact. Alternatively, the second temperature sensor 41 may protrude into an upper portion of the cooking chamber 101 to further improve temperature detection accuracy.

Alternatively, as shown in FIG. 3, in embodiments where pan body assembly 10 includes a pan body 14 and an outer shell 13, pan body 14 may include an inner pan and an outer pan, the inner pan disposed within the outer pan, and the inner pan having a cooking cavity 101. The first temperature sensor 40 may be provided at the outer pot, and the first temperature sensor 40 may be abutted against the lower wall surface of the inner pot to detect the temperature of the lower portion of the cooking chamber 101 by detecting the temperature of the lower wall surface of the inner pot.

In the example shown in fig. 3, the first temperature sensor 40 has a detecting portion that abuts against the lower wall surface of the inner pot to detect the temperature of the lower wall surface of the inner pot, and an elastic member. When the inner pot is placed in the outer pot, the inner pot compresses the elastic piece, so that the detection part can be tightly attached to the lower wall surface of the inner pot, and the temperature detection precision is improved. In fig. 3, the detection part passes through the lower wall surface of the inner pan, showing that the detection part abuts against the lower wall surface of the inner pan, the elastic member is shown in an uncompressed state, while the elastic member is actually in a compressed state, and the detection part abuts against the lower wall surface of the inner pan.

Alternatively, as shown in fig. 2 and 3, the fan 34 may be disposed above the second heating assembly 33, so that the fan 34 blows hot air into the cooking cavity 101 more efficiently.

In embodiments where the lid assembly includes the second lid assembly 30 and the second lid assembly 30 is coupled to the body assembly 10, the fan 34 may be coupled to the second coupler 32. When the cooking appliance 100 is in the second cooking mode, the second coupler 32 is coupled to the first coupler 11 to energize the fan 34.

According to some embodiments of the present invention, as shown in FIG. 6, the first cooking mode includes a pressure cooking stage in which the pressure inside the cooking chamber 101 is P1 and the difference between P1 and the normal pressure is P0 satisfies 40KPa ≦ P1-P0 ≦ 175 KPa.

Therefore, the pressure in the cooking cavity 101 is greater than the external pressure, positive pressure cooking of food is realized, the food can be stewed and stewed under the positive pressure cooking state, the food cooking efficiency is high, the nutrition extraction effect is better, and the cooking temperature does not need to be too high under the positive pressure cooking state, for example, the temperature T1 in the cooking cavity 101 can meet the condition that the temperature T1 is more than or equal to 100 ℃ and is less than or equal to 135 ℃, so that the energy consumption is reduced. In some embodiments, the first predetermined temperature T1 may be 110 ℃, 115 ℃, 120 ℃, 125 ℃, 130 ℃, and the like.

It should be noted that P1 can be flexibly set according to actual needs. Alternatively, when the cooking food is a relatively hard food such as tendon, beef and mutton, etc., P1 may satisfy 80KPa ≦ P1-P0 ≦ 175KPa to improve the cooking efficiency as much as possible. For example, in some embodiments, the P1 may be 90KPa, 100KPa, 110KPa, 120KPa, 130KPa, 140KPa, 150KPa, 160KPa, 170KPa, and so on. Alternatively, when the cooking food is relatively easy-to-cook food, such as chicken, fish, etc., P1 may satisfy 40KPa ≦ P1-P0 ≦ 80KPa to reduce energy consumption while satisfying cooking efficiency. For example, in some embodiments, P1 may be 45KPa, 50KPa, 55KPa, 60KPa, 65KPa, 70KPa, 75KPa, and so on.

According to a further embodiment of the present invention, as shown in fig. 6, the first cooking mode may further include a step-down stage. When the first cooking mode is switched to the second cooking mode, the first lid assembly 20 needs to be replaced with the second lid assembly 30, that is, the first lid assembly 20 needs to be separated from the pot assembly 10. Since the pressure in cooking chamber 101 is positive during the pressure cooking stage, cooking appliance 100 enters the pressure reduction stage after the pressure cooking stage is finished. In the pressure reduction stage, the pressure in the cooking cavity 101 is reduced from P1 to P0, so that the first lid assembly 20 is easily separated from the body assembly 10, and no safety accident occurs. It should be noted that, in the pressure reduction stage, the temperature in the cooking cavity 101 is slightly reduced from T1 due to the effect of the pressure reduction in the cooking cavity 101, but the temperature reduction range is small, so that the waste heat in the first cooking mode can be utilized in the second cooking mode, which is beneficial to saving energy, reducing consumption and improving cooking efficiency.

Optionally, the way of reducing the pressure in the cooking cavity 101 during the pressure reduction stage can be flexibly set according to actual requirements. For example, it is within the scope of the present invention to control the opening of the exhaust valve or the water cooling during the depressurization phase.

According to the control method of the embodiment of the present invention, the first heating assembly 12 is switchably heated between at least two heating powers during the pressure cooking stage. Thus, the first heating assembly 12 can have more heating modes, and while meeting the temperature requirements of the first cooking mode, the first heating assembly 12 consumes less energy and does not need to operate continuously at high heating power, which is beneficial to improving the service life of the first heating assembly 12.

In some embodiments of the present invention, as shown in fig. 6, the second cooking mode may include an atmospheric cooking stage in which the pressure inside the cooking chamber 101 is atmospheric P0, the temperature inside the cooking chamber 101 is T2 and satisfies: t2 is more than or equal to 100 ℃ and less than or equal to 250 ℃. In the normal-pressure cooking stage, the control method can control the cooking appliance 100 to cook food at normal pressure and high temperature, the surface of the food is quickly cooked and is cooked into the food, and the surface of the food can reach different coking degrees according to different set values of T2, so that the food has different surface tastes.

Alternatively, if the user prefers a food with severe surface scorching and crispness, T2 may be selected to satisfy: 200 ℃ T2 ℃ 250 ℃, for example, in some embodiments, T2 can be 210 ℃, 220 ℃, 230 ℃, and 240 ℃, respectively, etc.

Alternatively, if the user prefers a food with a relatively light and less brittle surface scorch, then T2 may be selected to satisfy: t2 ≦ 200 ℃. for example, in some embodiments, T2 may be 110 ℃, 120 ℃, 130 ℃, 140 ℃, 150 ℃, 160 ℃, 170 ℃, 180 ℃, 190 ℃ and the like, respectively.

Further, during the atmospheric cooking phase, the second heating assembly 33 is switchably heated between at least two heating powers. Thus, the second heating assembly 33 can have more heating modes, and while meeting the temperature requirement of the second cooking mode, the second heating assembly 33 consumes less energy, and does not need to continuously operate at high heating power, which is beneficial to improving the service life of the second heating assembly 33.

According to some embodiments of the present invention, referring to FIG. 6, in the first cooking mode, the highest heating power of the first heating assembly 12 is W1, and in the second cooking mode, the highest heating power of the second heating assembly 33 is W2, wherein 0W < W1 ≦ 2100W and 0W < W2 ≦ 2100W. By adjusting the magnitude of the maximum heating power W1, the cooking temperature and the cooking pressure, etc. in the first cooking mode may be adjusted, and by adjusting the magnitude of the maximum heating power W2, the cooking temperature, etc. in the second cooking mode may be adjusted, so that the cooking appliance 100 may achieve more cooking effects in the first cooking mode and the second cooking mode, respectively.

For example, in some embodiments, W1 may be 250W, 500W, 750W, 1000W, 1250W, 1750W, 2000W, etc. and W2 may be 250W, 500W, 750W, 1000W, 1250W, 1750W, 2000W, etc. respectively.

It should be noted that, in the present invention, the maximum heating power W1 of the first heating assembly 12 and the maximum heating power W2 of the second heating assembly 33 are not necessarily related, that is, W1 may be greater than W2, or W may be equal to W2, or W1 may be smaller than W2.

Alternatively, as shown with reference to fig. 6, the first cooking mode may include a first pre-treatment stage. During the first pretreatment stage, the heating power of the first heating assembly 12 is uniformly increased from zero to the highest heating power W1 and is maintained at the highest heating power W1 until the first pretreatment stage is finished, and the pressure in the cooking chamber 101 is uniformly increased from the normal pressure P0 to P1 and is maintained at P1 until the first pretreatment stage is finished. Alternatively, the temperature inside the cooking chamber 101 may be uniformly raised from the normal temperature to T1 and maintained at T1 until the end of the first pre-treatment stage.
