A method of cooking porridge by a cooking appliance according to an embodiment of the present invention is described below with reference to the accompanying drawings. Here, the cooking appliance may be an electric cooker or an electric pressure cooker, etc.

Referring to fig. 1, a congee cooking method of a cooking appliance according to an embodiment of the present invention may include the steps of:

s1: and after receiving the porridge cooking instruction, controlling the cooking appliance to heat. For example, when a low-sugar porridge cooking button on the cooking appliance is triggered, the cooking appliance receives a porridge cooking instruction and starts to heat.

S2: and in the process of heating the cooking utensil and after the rice grains start to be gelatinized, injecting liquid into the cooking utensil to cool the rice porridge. Here, the liquid injected into the cooking appliance may be purified water, bottled water, or the like.

At present, the congee cooking method in the related technology generally boils the congee, slowly boils the congee to be well done until the rice is popped and completely gelatinized, and then finishes cooking. The porridge cooked by the porridge cooking method is fully gelatinized and easy to digest, has thick rice soup, is easy to convert into human blood sugar after being eaten, and is not suitable for people with sensitive blood sugar.

The gelatinized rice porridge is cooled by injecting liquid after rice grains begin to be gelatinized, the broken starch molecule hydrogen bonds after gelatinization are recombined at a lower temperature, the molecules are changed into an orderly arranged structure again, the starch in the rice porridge is cooled and regenerated and is converted into resistant starch, and therefore the content of the resistant starch in the porridge is improved, and the content of the digested starch is reduced. The resistant starch is difficult to digest, and the blood sugar conversion rate is low after the resistant starch is eaten, so that the effect of reducing the blood sugar is achieved. The rice porridge is more suitable for people with sensitive blood sugar and is more suitable for health preservation.

In the embodiment of the present invention, the liquid may be injected into the cooking utensil after the rice grains are completely gelatinized or after the rice grains are partially gelatinized.

And cooling the gelatinized layer on the surface of the rice grains to form a resistant starch crystalline layer, wherein the resistant starch crystalline layer wraps the starch in the rice grains to control the water absorption of the rice. The raw rice has high resistant starch originally, the higher the water content of the rice grains is, the easier the conversion of the resistant starch into the digestive starch is promoted, and the resistant starch is regenerated on the surface of the semi-cooked rice grains (namely the partially gelatinized rice grains) through cooling to form a resistant starch crystallization layer, so that the conduction of water and heat can be prevented, the conversion of the resistant starch in the rice grains in the cooking process is reduced, and the loss of the resistant starch is reduced. Therefore, when the rice grains are partially gelatinized, the liquid is injected into the cooking utensil, so that the original resistant starch of the rice grains can be greatly reserved, and the content of the resistant starch in the rice porridge can be improved.

In addition, the higher the degree of the early gelatinization is, the more sufficient the rice grains are gelatinized, the more sufficient the starch structure in the rice porridge is broken up, the more favorable the recombination of the starch structure of the subsequent cooling is, the generation of the resistant starch is promoted, the form of the resistant starch obtained by cooling and regeneration is relatively stable, and the resistant starch still can exist stably even if the rice porridge is reheated, so that the content of the resistant starch in the rice porridge is ensured. Therefore, when the rice grains are completely gelatinized, liquid is injected into the cooking utensil, more and more stable retrogradation resistant starch can be obtained, and the content of the resistant starch in the rice porridge is improved.

In some embodiments of the present invention, during heating of the cooking appliance, i.e. during the heating phase, if the temperature inside the cooking appliance is equal to or higher than the fourth preset temperature, it is determined that rice grains start to gelatinize. At the moment, liquid can be injected into the cooking utensil so as to cool and regenerate the gelatinized layer to form a resistant starch crystallization layer, thereby improving the content of resistant starch and reducing the conversion of original resistant starch in rice grains into consumed starch. In some embodiments, the fourth predetermined temperature may be 60 ℃, i.e., the temperature within the cooking appliance is greater than or equal to 60 ℃, determining that the rice grains begin to gelatinize. In some embodiments, the rice grains begin to gelatinize when the temperature in the cooking utensil is 60 deg.C, 65 deg.C, 70 deg.C, 75 deg.C, 80 deg.C, 85 deg.C, 90 deg.C, etc.

For example, in some embodiments, a liquid is injected into the cooking appliance during boiling in the cooking appliance. At the moment, most of the rice grains are gelatinized, and the gelatinized rice grains can be regenerated to form resistant starch by injecting liquid for cooling, so that the content of the resistant starch is obviously improved, a resistant starch crystallization layer is formed, and the original resistant starch in a small part of ungelatinized rice grains is prevented from being converted into digestive starch. Optionally, after the liquid is injected, the cooking appliance can be controlled to continue heating, and the rice core is gelatinized by using the waste heat, so that the cooked rice core of the rice porridge is just cooked, and the effect of resistant starch is better.

For example, in some embodiments, as shown in fig. 4, after the cooking appliance completes the boiling process, a liquid is injected into the cooking appliance. At the moment, the rice grains are completely gelatinized, the starch structure in the rice porridge is more fully broken, and the whole rice grains are quickly cooled and regenerated by injecting liquid to obtain more resistant starch with stable structure, so that the content of the resistant starch is obviously improved.

For example, in some embodiments, the liquid injection into the cooking appliance may begin at around 80% of rice grain gelatinization.

According to the porridge cooking method of the cooking utensil, disclosed by the embodiment of the invention, the liquid is injected into the cooking utensil after rice grains start to be gelatinized in the heating process of the cooking utensil, so that the starch in the porridge is cooled and regenerated and converted into resistant starch, and thus the content of the resistant starch in the porridge is increased and the content of the digested starch is reduced. The resistant starch is difficult to digest, and the blood sugar conversion rate is low after the resistant starch is eaten, so that the effect of reducing the blood sugar is achieved.

In some embodiments of the present invention, as shown in fig. 3 and 4, after receiving the congee cooking instruction, the cooking appliance is controlled to sequentially perform a water absorption phase, a heating phase and a boiling phase. For example, in some embodiments, rice and water are placed in the cooking appliance, and when the cooking appliance is heated after receiving a cooking instruction for cooking porridge, the cooking appliance is heated to the third preset temperature T3, enters the water absorption phase, and is maintained at the third preset temperature T3 for the third preset time T3 in the water absorption phase. Heating is then continued to boil. Wherein the third preset temperature T3 and the third preset time T3 satisfy: t3 is more than or equal to normal temperature and less than 60 ℃, T3 is more than 0min and less than or equal to 20 min. For example, in some embodiments, the third predetermined temperature T3 may be 30 ℃, 35 ℃, 40 ℃, 45 ℃, 50 ℃, 55 ℃ and the like, and the third predetermined time T3 may be 2min, 5min, 8min, 10min, 13min, 15min, 18min and the like.

In other embodiments of the present invention, after receiving the cooking instruction of congee, the cooking appliance is controlled to be heated to directly enter the boiling stage, in other words, after receiving the cooking instruction of congee, the water absorption stage is cancelled, and the cooking appliance is directly heated to the boiling stage. The rice grains can be quickly pasted to be well-done by canceling the water absorption stage, the water content of the rice grains is reduced, the pasting degree of the rice grains which do not absorb water is lower than that of the rice grains after absorbing water, the resistant starch content is high, the resistant starch content in the porridge can be further improved, and the better blood sugar reducing effect can be achieved.

According to some embodiments of the present invention, as shown in fig. 3 and 4, after the liquid is injected into the cooking appliance, the cooking appliance is further controlled to continue heating to the first preset temperature. On the one hand, the rice porridge can be pasted more fully, and due to the existence of the resistant starch crystallization layer, the starch in rice grains is prevented from being converted into the digestive starch, and on the other hand, the temperature of the rice porridge is enabled to better meet the edible requirements of users, and the user experience is improved.

In some embodiments, the first preset temperature T1 may satisfy: t1 is more than or equal to 50 ℃ and less than or equal to 95 ℃. Within the temperature range, the rice porridge has better taste and higher resistant starch content. For example, in some embodiments, the first predetermined temperature T1 may be 55 ℃, 60 ℃, 65 ℃, 70 ℃, 75 ℃, 80 ℃, 85 ℃, 90 ℃ or the like. Preferably, the first preset temperature T1 may satisfy: t1 is more than or equal to 55 ℃ and less than or equal to 80 ℃.

According to some embodiments of the present invention, the temperature of the liquid injected into the cooking appliance is less than or equal to the second preset temperature, so that the rice gruel in the cooking appliance is cooled more quickly, thereby improving the conversion effect of the resistant starch and the blood sugar reduction effect. In some embodiments, the second preset temperature may be normal temperature or lower.

In some embodiments, after the liquid is injected into the cooking appliance, the temperature in the cooking appliance is less than or equal to a fifth preset temperature, so that the rice grains in the cooking appliance can be sufficiently cooled and regenerated, and the resistant starch content is increased.

In some embodiments, the fifth predetermined temperature may be 60 ℃, for example, in some embodiments, after injecting the liquid into the cooking appliance, the temperature in the cooking appliance may be reduced to 55 ℃, 50 ℃, 45 ℃, 40 ℃, 35 ℃, 30 ℃, 25 ℃, 20 ℃, 15 ℃, 10 ℃ and the like. Preferably, the temperature in the cooking appliance can be lowered to less than 30 ℃, and the effect of increasing the resistant starch content is better.

According to some embodiments of the invention, the rice-to-water ratio added to the cooking appliance is greater than a preset standard porridge rice-to-water ratio before the cooking appliance is heated. In other words, the amount of water added to the cooking appliance before it is heated is less than the preset standard amount of porridge water. Thus, after the cooking appliance is filled with liquid to return the porridge, the resulting porridge has a rice-to-water ratio substantially equal to that of standard porridge cooking, and the cooked porridge has a better mouthfeel.

In the embodiment of the present invention, the liquid injected into the cooking appliance may be stored in the cooking appliance in advance, or may be provided by a liquid supply device (a water purifier, an external water tank, a water bottle, etc.) outside the cooking appliance.

For example, in some embodiments, a cooking appliance includes a cooking body defining a cooking cavity and a liquid injection device disposed in the cooking body and coupled to an external liquid supply device. When liquid is injected into the cooking appliance, the liquid in the external liquid supply equipment is guided into the cooking cavity by controlling the liquid injection device, so that the structure of the cooking appliance is simplified.

For another example, in other embodiments, a cooking appliance includes a cooking body defining a cooking cavity and a reservoir cavity, and a liquid injection device disposed in the cooking body. When liquid is injected into the cooking appliance, the liquid in the liquid storage cavity is guided into the cooking cavity by controlling the liquid injection device. Cooking utensil itself has the stock solution function, makes cooking utensil's the place environment unrestricted, and utilizes stock solution chamber stock solution to be convenient for control liquid volume, liquid temperature etc..

In some embodiments, the cooking appliance further comprises a refrigerating device arranged in the cooking main body to refrigerate the liquid in the liquid storage cavity. Therefore, the liquid injected into the cooking utensil is cold liquid (or cool liquid) with lower temperature, so that the regeneration speed and effect of the rice porridge are accelerated, and the better low-sugar effect is realized.

In the embodiment including the refrigerating device, after receiving the cooking instruction of cooking congee, the refrigerating device can be controlled to refrigerate immediately, and can also refrigerate after delaying preset time, for example, the refrigerating device can refrigerate in a heating stage or a boiling stage, so that the requirement of timely injecting liquid into the cooking appliance can be met, and the energy consumption is improved due to long-time storage and heat preservation of cold liquid.

In some embodiments, the refrigeration device may comprise a refrigeration member. The refrigeration piece has the portion of generating heat and refrigeration portion, and the wall contact cooperation in refrigeration portion and stock solution chamber to refrigerate the liquid in the stock solution intracavity. In some embodiments, the cooling device may further include a heat dissipation device disposed adjacent to the heat generating portion for dissipating heat from the heat generating portion, thereby improving the cooling efficiency of the cooling component.

Alternatively, the cooling member may be a semiconductor cooling plate. Based on the operating principle of the Peltier effect, when voltage is applied to the semiconductor refrigerating sheet, electrons are transferred from the first end to the second end of the semiconductor refrigerating sheet, the temperature of the first end is reduced to form a refrigerating part, and the temperature of the second end is increased to form a heating part.

In some embodiments, the heat dissipation device may include a heat exchanger disposed near or in contact with the heat generating portion to exchange heat with the heat generating portion, and a cooler connected to the heat exchanger to form a heat dissipation loop in which a cooling medium circulates. The cooling medium absorbs heat from the heat generating part in the heat exchanger and achieves cooling in the cooler. The heat dissipation device can further comprise a heat dissipation fan, the heat dissipation fan is arranged close to the cooler and used for driving air around the cooler to flow, so that the temperature of the cooler is reduced, the cooling effect of the cooler on cooling media is improved, the improvement of the refrigeration efficiency of the refrigeration part is facilitated, and the potential safety hazard caused by overhigh temperature of the heating part is reduced.

In the embodiment that the refrigerating element is a semiconductor refrigerating sheet, after cooking is finished, reverse voltage can be applied to the semiconductor refrigerating sheet, so that electrons migrate from the second end to the first end of the semiconductor refrigerating sheet, the temperature of the second end is reduced to form a refrigerating part, and the temperature of the first end is increased to form a heating part. At the moment, the heating part is in contact fit with the wall of the liquid storage cavity to heat the liquid storage cavity, so that the temperature of the liquid remaining in the liquid storage cavity is increased and the liquid remaining in the liquid storage cavity is evaporated, the phenomenon that the liquid remaining in the liquid storage cavity is easy to mildew is avoided, the generated liquid vapor can also sterilize and disinfect the liquid storage cavity, and the sanitary condition of the cooking appliance is improved.

According to some embodiments of the invention, the liquid injection device may further comprise a spraying assembly, wherein the liquid introduced into the cooking cavity is further sprayed by the spraying assembly. So that pour into the liquid of culinary art intracavity with the rice direct contact who sprays with wider within range to spray the processing procedure, be favorable to forming the liquid fog, the liquid fog can spread to the bottom of culinary art chamber, with the rice contact cooling that is located the culinary art chamber bottom, thereby improve the cooling homogeneity of reviving of whole culinary art intracavity rice.

In some embodiments, the spray assembly may have at least one nozzle, which may be a small hole or a gap, to facilitate the formation of the liquid mist. In embodiments where the spray assembly has multiple spray orifices, the multiple spray orifices are capable of spraying to a greater extent and also facilitate the formation of a liquid mist.

Since the congee cooking method of the cooking appliance according to the embodiment of the first aspect of the present invention has the above-mentioned advantageous technical effects, the computer-readable storage medium according to the embodiment of the second aspect of the present invention, on which the congee cooking program is executed, allows the starch in the congee to be cooled back to be converted into resistant starch by injecting a liquid into the cooking appliance after the rice grains start to be gelatinized during the heating of the cooking appliance, thereby increasing the content of the resistant starch in the congee and reducing the content of the digested starch. The resistant starch is difficult to digest, and the blood sugar conversion rate is low after the resistant starch is eaten, so that the effect of reducing the blood sugar is achieved.

The cooking appliance according to the third aspect of the invention comprises a memory, a processor and a porridge cooking program of the cooking appliance stored on the memory and capable of running on the processor, and when the processor executes the porridge cooking program, the porridge cooking method of the cooking appliance according to the first aspect of the invention is realized.

Since the cooking method of the cooking utensil according to the first aspect of the present invention has the above-mentioned beneficial technical effects, the cooking utensil according to the third aspect of the present invention can increase the content of resistant starch in the rice gruel and reduce the content of digested starch by injecting liquid into the cooking utensil after the rice grains begin to gelatinize during the heating process of the cooking utensil to cool the starch in the rice gruel and convert the starch into the resistant starch. The resistant starch is difficult to digest, and the blood sugar conversion rate is low after the resistant starch is eaten, so that the effect of reducing the blood sugar is achieved.

Upon receiving the congee cooking instruction, control device 30 controls heating device 50 to operate so that cooking appliance 100 is heated. For example, when the low-sugar porridge cooking button on the cooking appliance 100 is activated, the control device 30 receives a porridge cooking command and controls the heating device 50 to operate to heat the cooking appliance 100.

And the control device 30 controls the liquid injection device 20 to introduce the liquid in the liquid storage cavity 102 into the cooking cavity 101 so as to cool the rice porridge after the rice grains start to be gelatinized during the heating process of the cooking appliance 100. Here, the liquid injected into the cooking appliance 100 may be purified water, bottled water, or the like. Cooking utensil 100 itself has the stock solution function, makes cooking utensil 100 place the environment unrestricted, and utilizes stock solution chamber 102 stock solution to be convenient for control liquid volume, liquid temperature etc..

The cooking utensil 100 of the invention cools the gelatinized rice porridge by injecting liquid after the rice grains begin to be gelatinized, the molecules of the gelatinized starch are recombined by the broken molecular hydrogen bonds of the starch after being gelatinized at a lower temperature, and the molecules are changed into an orderly arranged structure again, so that the starch in the rice porridge is cooled and regenerated and is converted into resistant starch, thereby improving the content of the resistant starch in the porridge and reducing the content of the digested starch. The resistant starch is difficult to digest, and the blood sugar conversion rate is low after the resistant starch is eaten, so that the effect of reducing the blood sugar is achieved. The rice porridge is more suitable for people with sensitive blood sugar and is more suitable for health preservation.

In the embodiment of the present invention, the controller 30 controls the liquid filling device 20 to introduce the liquid in the liquid storage chamber 102 into the cooking chamber 101, and the rice grains may be completely gelatinized or partially gelatinized.

The raw rice has high resistant starch originally, the higher the water content of the rice grains is, the easier the conversion of the resistant starch into the digestive starch is promoted, and the resistant starch is regenerated on the surface of the semi-cooked rice grains (namely the partially gelatinized rice grains) through cooling to form a resistant starch crystallization layer, so that the conduction of water and heat can be prevented, the conversion of the resistant starch in the rice grains in the cooking process is reduced, and the loss of the resistant starch is reduced. Therefore, when the rice grains are partially gelatinized, the control device 30 controls the liquid injection device 20 to introduce the liquid in the liquid storage cavity 102 into the cooking cavity 101, so that the original resistant starch of the rice grains can be greatly reserved, and the content of the resistant starch in the rice porridge can be improved.

In addition, the higher the degree of the early gelatinization is, the more sufficient the rice grains are gelatinized, the more sufficient the starch structure in the rice porridge is broken up, the more favorable the recombination of the starch structure of the subsequent cooling is, the generation of the resistant starch is promoted, the form of the resistant starch obtained by cooling and regeneration is relatively stable, and the resistant starch still can exist stably even if the rice porridge is reheated, so that the content of the resistant starch in the rice porridge is ensured.

In some embodiments, the third predetermined temperature may be 60 ℃, i.e., the temperature within the cooking appliance is greater than or equal to 60 ℃, determining that the rice grains begin to gelatinize.

At the moment, most of the rice grains are gelatinized, and the gelatinized rice grains can be regenerated to form resistant starch by injecting liquid for cooling, so that the content of the resistant starch is obviously improved, a resistant starch crystallization layer is formed, and the original resistant starch in a small part of ungelatinized rice grains is prevented from being converted into digestive starch. Optionally, after the liquid is injected, the cooking appliance 100 can be controlled to continue heating, and the rice core is gelatinized by using the waste heat, so that the cooked rice core of the rice porridge is just cooked, and the effect of resistant starch is better.

For example, in some embodiments, as shown in fig. 4, after the cooking appliance 100 completes the boiling process, the control device 30 controls the liquid injection device 20 to introduce the liquid in the liquid storage chamber 102 into the cooking chamber 101. At the moment, the rice grains are completely gelatinized, the starch structure in the rice porridge is more fully broken, and the whole rice grains are quickly cooled and regenerated by injecting liquid to obtain more resistant starch with stable structure, so that the content of the resistant starch is obviously improved.

For example, in some embodiments, the liquid injection into cooking appliance 100 may begin at around 80% rice gelatinization.

According to the cooking appliance 100 of the embodiment of the invention, the control device 30 controls the liquid injection device 20 to introduce the liquid in the liquid storage cavity 102 into the cooking cavity 101 during the heating process of the cooking appliance 100 and after the rice grains start to be gelatinized, so that the starch in the rice porridge is cooled and regenerated and converted into resistant starch, the content of the resistant starch in the rice porridge is increased, and the content of the digested starch is reduced. The resistant starch is difficult to digest, and the blood sugar conversion rate is low after the resistant starch is eaten, so that the effect of reducing the blood sugar is achieved.

In some embodiments of the present invention, as shown in fig. 3 and 4, when control device 30 controls cooking appliance 100 to operate, cooking appliance 100 is controlled to sequentially perform a water absorption phase, a heating phase, and a boiling phase. For example, in some embodiments, rice and water are placed in cooking appliance 100, cooking appliance 100 receives a congee cooking instruction, heats to a third predetermined temperature T3, enters a water absorption phase, and maintains the third predetermined temperature T3 for a third predetermined time T3 during the water absorption phase. Heating is then continued to boil. Wherein the third preset temperature T3 and the third preset time T3 satisfy: t3 is more than or equal to normal temperature and less than 60 ℃, T3 is more than 0min and less than or equal to 20 min. For example, in some embodiments, the third predetermined temperature T3 may be 30 ℃, 35 ℃, 40 ℃, 45 ℃, 50 ℃, 55 ℃ and the like, and the third predetermined time T3 may be 2min, 5min, 8min, 10min, 13min, 15min, 18min and the like.

In other embodiments of the present invention, when the control device 30 controls the cooking appliance 100 to operate, the cooking appliance 100 is controlled to be heated to directly enter the boiling stage, in other words, when the cooking appliance 100 is controlled to operate, the water absorption stage is cancelled, and the cooking appliance is directly heated to the boiling stage. The rice grains can be quickly pasted to be well-done by canceling the water absorption stage, the water content of the rice grains is reduced, the pasting degree of the rice grains which do not absorb water is lower than that of the rice grains after absorbing water, the resistant starch content is high, the resistant starch content in the porridge can be further improved, and the better blood sugar reducing effect can be achieved.

According to some embodiments of the present invention, as shown in fig. 3 and 4, after the control device 30 controls the liquid injection device 20 to introduce the liquid in the liquid storage chamber 102 into the cooking chamber 101, the cooking appliance 100 is further controlled to continue heating to the first preset temperature. On the one hand, the rice porridge can be pasted more fully, and due to the existence of the resistant starch crystallization layer, the starch in rice grains is prevented from being converted into the digestive starch, and on the other hand, the temperature of the rice porridge is enabled to better meet the edible requirements of users, and the user experience is improved.

According to some embodiments of the present invention, the temperature of the liquid injected into the cooking appliance 100 is less than or equal to the second preset temperature, so that the rice porridge in the cooking appliance 100 is cooled more rapidly, thereby improving the conversion effect of the resistant starch and the blood sugar reduction effect. In some embodiments, the second preset temperature may be normal temperature or lower.

In some embodiments, after the liquid is injected into the cooking appliance 100, the temperature inside the cooking appliance 100 is less than or equal to the fifth preset temperature, so that the rice grains inside the cooking appliance 100 can be sufficiently cooled and retrograded, thereby increasing the resistant starch content.

In some embodiments, the fifth predetermined temperature may be 60 ℃, for example, in some embodiments, after injecting the liquid into the cooking appliance, the temperature in the cooking appliance 100 may be reduced to 55 ℃, 50 ℃, 45 ℃, 40 ℃, 35 ℃, 30 ℃, 25 ℃, 20 ℃, 15 ℃, 10 ℃, and the like. Preferably, the temperature in the cooking appliance 100 can be lowered to less than 30 ℃, and the effect of increasing the resistant starch content is better.

According to some embodiments of the present invention, the ratio of rice to water added to the cooking chamber 101 before the cooking appliance 100 is heated is greater than a preset standard porridge rice to water ratio. In other words, before the cooking appliance 100 is heated, the amount of water added into the cooking cavity 101 is less than the preset standard amount of porridge water. Thus, after pouring water into the cooking cavity 101 to return the porridge, the resulting porridge has a rice-to-water ratio substantially equal to that of standard porridge, and the cooked porridge has a better taste.

In some embodiments of the present invention, as shown in fig. 2, the cooking appliance 100 further includes a refrigerating device 40, and the refrigerating device 40 is disposed on the cooking main body 10 to refrigerate the liquid in the liquid storage chamber 102. Thus, the liquid injected into the cooking appliance 100 is a cold liquid (or cool liquid) having a relatively low temperature, thereby accelerating the retrogradation speed and effect of the rice porridge and realizing a better low sugar effect.

In the embodiment including the refrigerating device 40, after receiving the congee cooking instruction, the refrigerating device 40 may be controlled to immediately refrigerate, or refrigerate after delaying a predetermined time, for example, refrigerate in a heating stage or a boiling stage, which not only meets the requirement of timely injecting liquid into the cooking appliance 100, but also avoids storing cold liquid for a long time and keeping the temperature, thereby improving energy consumption.

In some embodiments, the refrigeration device 40 may include a refrigeration member. The refrigeration member has a heat generating portion and a refrigeration portion that is in contact fit with the wall of the reservoir 102 to refrigerate the liquid in the reservoir 102. In some embodiments, the cooling device 40 may further include a heat dissipation device disposed adjacent to the heat generating portion for dissipating heat from the heat generating portion, thereby improving the cooling efficiency of the cooling component.

In the embodiment that the refrigerating element is a semiconductor refrigerating sheet, after cooking is finished, reverse voltage can be applied to the semiconductor refrigerating sheet, so that electrons migrate from the second end to the first end of the semiconductor refrigerating sheet, the temperature of the second end is reduced to form a refrigerating part, and the temperature of the first end is increased to form a heating part. At this time, the heat generating portion contacts and cooperates with the wall of the liquid storage cavity 102 to heat the liquid storage cavity 102, so that the liquid remaining in the liquid storage cavity 102 is heated and evaporated, the liquid remaining in the liquid storage cavity 102 is prevented from being easy to mildew, and the generated water vapor can sterilize and disinfect the liquid storage cavity 102, thereby improving the sanitary condition of the cooking utensil 100.
