[0001] The present invention relates to the technical field of cooking, and particularly to a control method for a cooking appliance, a cooking appliance, and a readable storage medium. Background Art

[0002] Existing cooking appliances discharge a large amount of steam during the cooking process. The high-temperature and high-humidity steam can cause the temperature and humidity in a narrow kitchen environment, making the kitchen humid, which can easily affect the service life of kitchen cabinets and kitchen appliances, etc., and there is also a safety risk of scalding users. In related technologies, a condensation chamber can be set so that the steam is discharged into the condensation chamber and contacts with cooling water to condense into water, thereby reducing or avoiding the outward discharge of steam. However, if the amount of cooling water in the condensation chamber is low, it is easy to cause the cooling water to be heated by the steam and increase in temperature, affecting the condensation efficiency; if the amount of cooling water in the condensation chamber is high, there is an easy problem of water overflow. Summary of the Invention

[0011] In an embodiment of the present application, in the step of setting the power adjustment of the boiling stage of the cooking appliance to a second preset power adjustment under the condition that the water volume value of the condensation chamber is not within the preset water volume range, it includes:

[0012] Under the condition that the water volume value in the condensation chamber is not within the preset water volume range, issue an instruction to adjust the water volume in the condensation chamber;

[0013] After issuing the instruction to adjust the water volume in the condensation chamber and after a preset time, if the water volume value in the condensation chamber is not within the preset water volume range, then set the power adjustment in the boiling stage to the second preset power adjustment.

[0014] In an embodiment of the present application, in the step of, after issuing the instruction to adjust the water volume in the condensation chamber and after a preset time, if the water volume value in the condensation chamber is not within the preset water volume range, then set the power adjustment in the boiling stage to the second preset power adjustment, it includes:

[0015] After issuing the instruction to adjust the water volume in the condensation chamber and after a preset time, if the water volume in the condensation chamber is not within the preset water volume range;

[0016] Set the power adjustment in the cooking stage before the boiling stage to the first preset power adjustment, and set the power adjustment in the boiling stage to the second preset power adjustment.

[0017] In an embodiment of the present application, before the step of setting the power adjustment in the boiling stage of the cooking appliance to the second preset power adjustment, it further includes:

[0018] Under the condition that the temperature in the cooking space reaches the preset temperature, confirm that it enters the boiling stage.

[0019] In an embodiment of the present application, the step of, under the condition that the temperature in the cooking space reaches the preset temperature, confirm that it enters the boiling stage, includes:

[0020] Under the condition that the temperature in the cooking space is not lower than 95 °C, confirm that it enters the boiling stage.

[0021] In an embodiment of the present application, in the step of, under the condition that the water volume value in the condensation chamber is not within the preset water volume range, set the power adjustment in the boiling stage of the cooking appliance to the second preset power adjustment, it includes:

[0022] Under the condition that the water volume value in the condensation chamber is lower than the preset minimum water volume, set the power adjustment in the boiling stage of the cooking appliance to the second preset power adjustment.

[0023] In an embodiment of the present application, in the step of, under the condition that the water volume value in the condensation chamber is not within the preset water volume range, set the power adjustment in the boiling stage of the cooking appliance to the second preset power adjustment, it includes:

[0024] Under the condition that the water volume value in the condensation chamber exceeds the preset maximum water volume, set the power adjustment in the boiling stage of the cooking appliance to the second preset power adjustment.

[0028] According to the technical solution of the present invention, when the water quantity value in the condensation chamber is not within the preset water quantity range, the steam emission can be reduced by reducing the heating power adjustment during the cooking process. During the cooking process, the amount of steam generated is related to the heating power adjustment of the cooking appliance. The heating power adjustment is the ratio of the heating time of the cooking appliance within a power adjustment cycle to the time of the power adjustment cycle. When the water quantity in the condensation chamber is outside the preset water quantity range, the power adjustment of the cooking appliance in the boiling stage can be set to a second preset power adjustment, so that the cooking appliance heats and cooks at the second preset power adjustment in the boiling stage, thereby reducing the boiling degree in the boiling stage, reducing steam generation, and enabling more water to be absorbed by the ingredients.

[0029] With such a setting, when the water quantity value in the condensation chamber is lower than the lowest preset water quantity, reducing the heating power adjustment can prevent the water in the condensation chamber from being quickly heated up as it enters with the steam, resulting in a decrease in the condensation efficiency, so as to ensure the steam condensation efficiency and ensure the effect of no steam or micro-steam emission. When the water quantity value in the condensation chamber is higher than the highest preset water level, reducing the heating power adjustment can prevent the water quantity in the condensation chamber from increasing too much, resulting in an overflow problem, and improve the use safety.

[0046] The present invention provides a control method for a cooking appliance 100. This control method can be applied to rice cookers, pressure cookers, steamers, steam ovens, or other appliances that generate steam during the cooking process.

[0047] For ease of explanation, in the embodiments of this application, rice cooking in a rice cooker is taken as an example. For different cooking appliances 100 and cooking processes, they can generally be divided into a heating stage, a boiling stage, and a warming stage. When cooking rice in a rice cooker, the warming stage is also similar to the simmering stage. Additionally, during the cooking process, the main stage for generating steam is the boiling stage.

[0048] A cooking space 111 for placing and cooking food ingredients is formed within the appliance main body 10 of the cooking appliance 100, and a condensation chamber 131 communicating with the cooking space 111 is formed. The condensation chamber 131 is connected to the cooking space 111 through a communication channel. When using the cooking appliance 100, cooling water can be stored in the condensation chamber 131 first, so that the steam generated during the cooking process of the cooking appliance 100 can flow into the condensation chamber 131 through the communication channel and contact the cooling water to condense into water, reducing or avoiding the discharge of steam to the outside of the cooking appliance 100, achieving the purpose of micro-steam or steam-free discharge during the cooking process, thereby avoiding the impact of steam on the surrounding environment and avoiding scalding the user by steam.

[0049] Please refer to Figure 3 , in some embodiments of the control method for the cooking appliance 100 of this application, the control method includes the following steps:

[0050] Step S10, obtaining the water quantity value of the condensation chamber 131;

[0051] Step S20, under the condition that the water quantity value of the condensation chamber 131 is within a preset water quantity range, setting the power adjustment of the boiling stage of the cooking appliance to a first preset power adjustment;

[0052] Step S30, under the condition that the water quantity value of the condensation chamber 131 is not within the preset water quantity range, setting the power adjustment of the boiling stage of the cooking appliance to a second preset power adjustment, and the second preset power adjustment is less than the first preset power adjustment.

[0053] Since the process of steam entering the condensation chamber 131 for condensation is also a process of heat transfer, it will cause the water temperature of the cooling water to rise, and the water volume value in the condensation chamber 131 will also increase as the steam continues to condense. Additionally, in some embodiments, the steam is directly discharged into the cooling water, and some uncondensed steam floats up from the cooling water, which may also cause the cooling water to vibrate or even splash.

[0054] Under the condition of enabling the cooking appliance 100 for cooking, it is necessary to determine whether the water volume value in the condensation chamber 131 is within a preset water volume range. It should be understood that the preset water volume range can be set according to parameters such as the set heating power adjustment, heating power, and heating time under normal cooking conditions, and can also be combined with the cooking environment, the type of cooling water, and the condensation efficiency, etc. Generally, the preset water volume range is reflected by a preset minimum water volume and a preset maximum water volume. If the water volume value in the condensation chamber 131 is lower than the preset minimum water volume, it will cause the water temperature of the cooling water in the condensation chamber 131 to rise rapidly, which will affect the condensation efficiency of the steam in the condensation chamber 131. If the water volume value in the condensation chamber 131 is higher than the preset maximum water volume, as the steam continues to condense, it will cause the problem that the condensation chamber 131 is filled with water and is prone to overflow.

[0055] The steam generation amount during the cooking process is related to the heating power adjustment of the cooking appliance 100. The heating power adjustment is the ratio of the heating time of the cooking appliance 100 in one heating cycle to the time of the heating cycle. That is, assuming that the cooking stage is divided into multiple heating cycles, the heating power adjustment can reflect the heating time of each heating cycle. When the heating power adjustment is reduced, the intensity of boiling can be weakened, so that more water is absorbed by the ingredients, thereby reducing the steam generation amount. It can also slow down and reduce the amount of steam entering the condensation chamber 131 per unit time. With such a setting, when the water volume value in the condensation chamber 131 is lower than the preset minimum water volume, the rising speed of the cooling water can also be slowed down, avoiding the cooling water from quickly rising to a temperature range that is not conducive to condensation. When the water volume in the condensation chamber 131 is higher than the preset maximum water volume, it can avoid the problem that the water in the condensation chamber 131 increases to an overflow state due to the generation of more steam.

[0056] That is to say, in the embodiment of the present application, when the water quantity value in the condensation cavity 131 is within the preset water quantity range, the power adjustment in the boiling stage is set to the first preset power adjustment, so that the cooking appliance 100 performs heating cooking at the first preset power adjustment in the boiling stage; while when the water quantity value in the condensation cavity 131 is not within the preset water quantity range, the power adjustment in the boiling stage is set to the second preset power adjustment, so that the cooking appliance 100 performs cooking at the second preset power adjustment lower than the first preset power adjustment in the boiling stage. Among them, the first preset power adjustment can be regarded as the standard heating power adjustment of the cooking appliance 100 in the normal water quantity state, and the first preset power adjustment in different cooking stages or different cycles can be the same or different, only referring to the preset normal power adjustment in each stage and each cycle in the normal water quantity state; and cooking at the second preset power adjustment when the water quantity value in the condensation cavity 131 is not within the preset water quantity range means that the power adjustment needs to be reduced for cooking in this stage or this cycle.

[0057] It should be noted that in the embodiment of the present application, cooking at the second preset power adjustment only means that the heating power adjustment needs to be reduced when the cooling water quantity is not within the preset water quantity range. And in the embodiment of the present application, the situation where the water quantity of the cooling water in the condensation cavity is not within the preset water quantity range includes the situation where the water quantity is lower than the preset minimum water quantity or higher than the preset maximum water quantity; different second preset power adjustments can be set based on different situations; and in the same situation where the preset use requirements are not met, for example, different second preset power adjustments can be set according to different abnormal situations where the water quantity is lower than the preset minimum water quantity and higher than the preset maximum water quantity; in addition, when the cooling water quantity is not within the preset water quantity range, different second preset power adjustments can also be set for cooking according to the actual water quantity.

[0058] In addition, when the water volume value in the condensation chamber is within the preset water volume range, the cooking appliance 100 can always cook at the first preset power adjustment until the cooking ends. In some embodiments, the cooking process can be divided into multiple stages, and each stage can also be divided into multiple cycles; and the first preset power adjustment, i.e., the preset normal power adjustment, set in different stages or different cycles can be different. For example, when the cooking process is divided into a heating stage, a boiling stage, and a heat preservation stage, the heating power adjustments in the heating stage, the boiling stage, and the heat preservation stage can all be different. At this time, cooking at the first preset power adjustment or the second preset power adjustment defined in the embodiments of the present application means heating and cooking at the first preset power adjustment or the second preset power adjustment set in the current stage; the limitation that the second preset power adjustment is less than the first preset power adjustment means that the second preset power adjustment is less than the first preset power adjustment set in the same stage or cycle. For example, it is assumed that the first preset power adjustment in the heating stage is 1 and the second preset power adjustment is 0.8; the first preset power adjustment in the boiling stage is 0.6 and the second preset power adjustment is 0.3. At this time, under the condition that the cooling water meets the usage requirements throughout the cooking process, the cooking program will cook at the heating power adjustments of 1 and 0.6 in the heating stage and the cooking stage respectively. If the cooling water does not meet the usage requirements before the heating structure operates and it is temporarily impossible to adjust the cooling water, the cooking program will cook at the heating power adjustments of 0.8 and 0.3 in the heating stage and the cooking stage respectively. If the cooling water meets the usage requirements in the heating stage, but in the boiling stage, as steam continuously enters the condensation chamber 131, the cooling water does not meet the usage requirements, for example, the water temperature or water level rises. At this time, the cooking program can first cook at the heating power adjustments of 1 and 0.6 in the heating stage and the cooking stage respectively, and when it is confirmed that the cooling water does not meet the usage requirements during the boiling stage, continue cooking at the heating power adjustment of 0.3. Similarly, when the cooking stage is divided into multiple cycles and different heating power adjustments are set for different cycles, the cooking control can refer to the foregoing examples for illustration.

[0059] Among them, for the water volume detection of the cooling water in the condensation chamber 131, the water surface position can be directly detected by setting a detection structure such as an infrared photosensitive sensor to judge the water level of the cooling water. It is also possible to detect the total weight of the water tank 13 forming the condensation chamber 131 and the cooling water by setting a detection structure such as a weight sensor; in both cases, the water volume value in the condensation chamber 131 can be confirmed.

[0060] Therefore, it can be understood that, for the technical solution of the present application, when the water volume value in the condensation chamber 131 is not within the preset water volume range, the steam emission can be reduced by reducing the heating power adjustment during the cooking process. During the cooking process, the amount of steam generated is related to the heating power adjustment of the cooking appliance 100. The heating power adjustment is the ratio of the heating time of the cooking appliance 100 within a power adjustment cycle to the time of the power adjustment cycle. When the water volume in the condensation chamber 131 is outside the preset water volume range, the power adjustment of the cooking appliance during the boiling stage is set to the second preset power adjustment, and the cooking appliance is heated and cooked at the second preset power adjustment during the boiling stage, so as to reduce the boiling degree during the boiling stage, reduce the generation of steam, and enable more water to be absorbed by the food materials.

[0061] With such a setting, when the water volume value in the condensation chamber 131 is lower than the lowest preset water volume, heating and cooking at the second preset power adjustment can prevent the water in the condensation chamber 131 from being rapidly heated up as it enters with the steam, resulting in a decrease in the condensation efficiency, so as to ensure the steam condensation efficiency and ensure the effect of no steam or micro-steam emission. When the water volume value in the condensation chamber 131 is higher than the highest preset water level, heating and cooking at the second preset power adjustment can prevent the water volume in the condensation chamber 131 from increasing too much, resulting in an overflow problem, and improve the use safety.

[0062] Please refer to Figure 4 , in some embodiments of the present application, the step of obtaining the water volume value of the condensation chamber 131 includes: obtaining the water level value in the condensation chamber 131, and confirming the water volume value of the condensation chamber according to the water level value; and / or, obtaining the weight value of the water in the condensation chamber, and confirming the water volume value of the condensation chamber according to the weight value.

[0063] In this embodiment, at least one of the water level and the weight of the water in the condensation chamber is used as the judgment basis for the water volume value of the condensation chamber 131. Specifically, a detection structure such as an infrared photosensitive sensor can be set to directly detect the water surface position to obtain the water level value in the condensation chamber 131. The total weight of the water tank 13 forming the condensation chamber 131 and the cooling water can also be detected by setting a detection structure such as a weight sensor.

[0064] If the water level value is directly used as the judgment basis, the obtained water level value is compared with the preset water level range, and it can be compared with the preset highest water level and the preset lowest water level. If the current water level value is lower than the preset lowest water level or higher than the preset highest water level, it can be confirmed that the current water volume value in the condensation chamber 131 does not meet the water volume required for the normal cooking procedure; at this time, the heating power adjustment during the boiling stage can be adjusted to the second preset power adjustment.

[0065] Similarly, if the weight value of water is directly used as the judgment basis, the obtained weight value is compared with the preset weight range, and it can be compared with the preset maximum weight and the preset minimum weight. If the current weight value is lower than the preset minimum weight or higher than the preset maximum weight, it can be confirmed that the water volume value in the current condensation chamber 131 does not meet the water volume required for the normal cooking program; at this time, the heating power adjustment during the cooking process can be adjusted to the second preset power.

[0066] Of course, the water level and weight can be used as the judgment basis at the same time to improve the judgment accuracy of the water volume. In addition, in some embodiments, the water volume value in the condensation chamber 131 can also be adjusted by setting a water pumping structure. By adopting the method of adjusting the heating power, in the case of failures such as damage to the water pumping structure, the cooking appliance 100 can maintain the operating state without closing the cooking program for water replenishment or water reduction operations, reducing the impact on the cooking operation of the cooking appliance 100.

[0067] Please refer to Figure 5 , in some embodiments of the present application, in the step of setting the power adjustment during the boiling stage of the cooking appliance to the second preset power under the condition that the water volume value in the condensation chamber 131 is not within the preset water volume range, it includes:

[0068] Step S31, under the condition that the water volume value in the condensation chamber 131 is not within the preset water volume range, issue an instruction to adjust the water volume in the condensation chamber 131;

[0069] Step S32, after issuing the instruction to adjust the water volume in the condensation chamber 131 and after a preset time, if the water volume value in the condensation chamber 131 is not within the preset water volume range, set the power adjustment during the boiling stage to the second preset power.

[0070] In this embodiment, when it is detected that the water volume value in the condensation chamber 131 is not within the preset water volume range, an instruction to adjust the water volume in the condensation chamber 131 can be issued first. The instruction can be an indication signal, such as a buzzer, an indicator light, or information sent to the terminal, etc., to notify the user to add water to the condensation chamber 131 or reduce the water in the condensation chamber 131. If the cooking appliance 100 is provided with a water pumping structure that can inject water and drain water from the condensation chamber 131, the instruction can also be a control instruction to directly control the water pumping structure to automatically add water to the condensation chamber 131 or drain the water in the condensation chamber 131.

[0071] After a period of time when the instruction to adjust the water volume in the condensation chamber 131 is issued, the water volume value in the condensation chamber 131 is detected. If the water volume value in the condensation chamber 131 does not change significantly and is still outside the preset water volume range, it is confirmed that the user cannot adjust the water volume in the condensation chamber 131 in time or there is a fault in the water pumping structure. Thus, it is confirmed that the water volume in the condensation chamber 131 cannot be adjusted temporarily at the current stage. Then, the generation of steam can be reduced by reducing the heating power adjustment, and the power adjustment in the boiling stage is set to the second heating power adjustment, so that the cooking appliance 100 operates at the second preset power adjustment in the boiling stage for cooking, without interrupting the cooking program and reducing the impact on the cooking operation.

[0072] Please refer to Figure 8 , in some embodiments of the present application, in the step of issuing an instruction to adjust the water volume in the condensation chamber 131 under the condition that the water volume value in the condensation chamber 131 is not within the preset water volume range, it includes:

[0073] Step S311, under the condition that the water volume value in the condensation chamber 131 is lower than the preset minimum water volume, issue an instruction to add water to the condensation chamber 131;

[0074] Step S312, under the condition that the water volume value in the condensation chamber 131 is greater than the preset maximum water volume, issue an instruction to reduce the water volume in the condensation chamber 131.

[0075] It can be understood that when the water volume in the condensation chamber 131 is not within the preset water volume range, there are two cases, that is, the water volume value in the condensation chamber 131 is lower than the preset minimum water volume, and the water volume value in the condensation chamber 131 is greater than the preset maximum water volume. At this time, correspondingly, under the condition that the water volume value in the condensation chamber 131 is lower than the preset minimum water volume, it is necessary to add water to the condensation chamber 131 to make the water volume in the condensation chamber 131 reach the preset water volume range; under the condition that the water volume value in the condensation chamber 131 is greater than the preset maximum water volume, it is necessary to reduce the water volume in the condensation chamber 131 to make the water volume in the condensation chamber 131 reach the preset water volume range.

[0076] Please refer to Figure 6 , in some embodiments of the present application, in the step of setting the power adjustment in the boiling stage to the second preset power adjustment under the condition that the water volume value in the condensation chamber 131 is not within the preset water volume range after issuing the instruction to adjust the water volume in the condensation chamber 131 and after a preset time, it includes:

[0077] Step S321, after issuing the instruction to adjust the water volume in the condensation chamber and after a preset time, if the water volume in the condensation chamber is not within the preset water volume range, set the power adjustment in the cooking stage before the boiling stage to the first preset power adjustment, and set the power adjustment in the boiling stage to the second preset power adjustment.

[0078] It can be understood that during the cooking process, the main steam generation stage is the boiling stage of the liquid in the cooking space 111. In this embodiment, if after issuing an instruction to adjust the water volume in the condensation chamber 131, it is confirmed that the water volume in the condensation chamber 131 cannot be adjusted by other means temporarily, in order not to affect the cooking operation, the heating structure can be turned on for heating. Before entering the boiling stage, no steam is generated or the amount of steam generated is small and the steam generation process is slow in the cooking space 111. During this process, the power adjustment of the cooking appliance 100 is set to the first heating power adjustment, that is, when entering the boiling stage, the cooking appliance 100 operates according to the first heating power adjustment of the conventional standard to maintain a high heating and temperature-rising efficiency. When after entering the boiling stage, if it operates according to the heating power adjustment of the normal cooking procedure, at this time, a large amount of steam is generated, which easily causes the water in the condensation chamber 131 to quickly heat up, resulting in a decrease in the condensation rate or the water in the condensation chamber 131 to overflow. At this time, the power adjustment of the cooking appliance 100 is set to the second preset power adjustment, so that the cooking appliance 100 heats and cooks at the second preset power adjustment during the boiling stage, reducing the generation of steam during the boiling stage, so that the cooking appliance 100 can continue cooking without interruption, achieving the purpose of no steam or micro-steam emission, and no problems such as water overflow will occur.

[0079] It should be noted that in the embodiments of the present application, it is possible to determine whether the current stage is in the boiling stage by detecting whether there is a large amount of steam generated in the cooking space 111; it is also possible to confirm whether the current stage is in the boiling stage by the cooking time; it is also possible to confirm whether the current stage has entered the boiling stage by detecting any factor such as the temperature, pressure in the cooking space 111, the temperature, and water volume of the condensation chamber 131.

[0080] Please refer to Figure 7 , in some embodiments of the present application, before the step of setting the power adjustment of the cooking appliance in the boiling stage to the second preset power adjustment, it further includes:

[0081] Under the condition that the temperature of the cooking space 111 reaches the preset temperature, it is confirmed that it enters the boiling stage.

[0082] In this embodiment, it is confirmed whether it has entered the boiling stage by detecting the temperature in the cooking space 111. The temperature sensor 70 can be set on the outer side of the pot body 11 that forms the cooking space 111 in the cooking appliance 100, or can be set on the cover body assembly 30 and at the opening position of the cooking space 111, or can be set directly in the cooking space 111 to detect the temperature of the food ingredients. In addition, it can be set to detect the temperature of the cooking space 111 at regular intervals, or can be set to detect the temperature of the cooking space 111 in real time.

[0083] It is understandable that when the liquid in the food material boils, the boiling temperature under standard atmospheric pressure is approximately around 100 °C. If the temperature sensor 70 is located outside the pot body 11 that forms the cooking space 111 or is set on the lid body, due to the distance and the gap in the structure of the pot body 11, the temperature at the position where the temperature sensor 70 is located may be lower than 100 °C. Therefore, the set preset temperature value needs to be set according to the position where the temperature sensor 70 is set, and can also be combined with environmental factors such as the environment in which the cooking appliance 100 is applied.

[0084] When the detected temperature value reaches the preset temperature, for example, is consistent with the preset temperature, exceeds the preset temperature, or is lower than the preset temperature by a certain difference; it can be confirmed that the current has entered the boiling stage, and thus the step of heating and cooking with the second preset power adjustment can be executed.

[0085] In an embodiment of the present application, the step of confirming entering the boiling stage under the condition that the temperature in the cooking space 111 reaches the preset temperature includes:

[0086] Under the condition that the temperature in the cooking space 111 is not lower than 95 °C, it is confirmed that the boiling stage has been entered.

[0087] In this embodiment, when the temperature sensor 70 detects that the temperature in the cooking space 111 is not lower than 95 °C, it is confirmed that the boiling stage has been entered, and then heating and cooking can be performed with the second preset power adjustment to reduce the generation of steam, and to slow down the heating rate of the cooling water in the condensation chamber 131 under the condition that the water volume in the condensation chamber 131 is insufficient, so as to avoid the cooling water quickly heating up to a temperature range that is not conducive to condensation. In the case where the water level in the condensation chamber 131 is too high, it is avoided that a large amount of steam enters the condensation chamber 131 for condensation, resulting in the water volume value in the condensation chamber 131 increasing to a full state and overflowing.

[0088] In some embodiments of the present application, in the step of setting the power adjustment of the boiling stage of the cooking appliance 100 to the second preset power adjustment under the condition that the water volume value in the condensation chamber 131 is not within the preset water volume range, it includes:

[0089] Under the condition that the water volume value in the condensation chamber 131 is lower than the preset minimum water volume, the power adjustment of the boiling stage of the cooking appliance 100 is set to the second preset power adjustment.

[0090] In this embodiment, when the water volume value in the condensation chamber 131 is less than the preset minimum water volume, the heating power adjustment during the cooking process is reduced; thereby, the amount of steam generated per unit time and the steam flow rate can be reduced, and the amount of steam entering the condensation chamber 131 per unit time can be slowed down and reduced. With such a setting, the heating rate of the cooling water in the condensation chamber 131 can be slowed down, and it is avoided that the cooling water quickly heats up to a temperature range that is not conducive to condensation.

[0091] In some embodiments of the present application, in the step of setting the power adjustment of the boiling stage of the cooking appliance 100 to a second preset power adjustment under the condition that the water volume value in the condensation chamber 131 is not within the preset water volume range, it includes:

[0092] Under the condition that the water volume value in the condensation chamber 131 exceeds the preset maximum water volume, set the power adjustment of the boiling stage of the cooking appliance 100 to the second preset power adjustment.

[0093] In this embodiment, when the water volume value in the condensation chamber 131 is higher than the preset maximum water volume, the heating and cooking are also carried out at the second preset power adjustment to slow down and reduce the amount of steam entering the condensation chamber 131 per unit time. This avoids the situation where, when the water level in the condensation chamber 131 is too high, a large amount of steam enters the condensation chamber 131 for condensation, resulting in an increase in the cooling water in the condensation chamber 131 to a full state and overflowing.

[0094] Please refer to Figure 1 and Figure 2 , the present application also proposes a cooking appliance 100, the cooking appliance 100 includes an appliance main body 10 and a water volume detection structure 50, a cooking space 111 and a condensation chamber 131 are formed in the appliance main body 10 and are in communication with each other, and the water volume detection structure 50 is used to detect the water volume value in the condensation chamber 131; the cooking appliance 100 can perform cooking by using the control method described in any of the foregoing embodiments.

[0095] The cooking appliance 100 proposed by the present application can be an electric rice cooker, a pressure cooker, a steam box, a steam oven or other appliances that generate steam during the cooking process.

[0096] In some embodiments, the cooking appliance 100 includes an appliance main body 10 and a lid assembly 30. A cooking space 111 and a condensation chamber 131 are formed in the appliance main body 10. A diversion channel 31 is formed in the lid assembly 30, and both the inlet 33 and the outlet 35 of the diversion channel 31 are located on the inner surface of the lid assembly 30. When the lid assembly 30 is closed on the appliance main body 10, the inlet 33 communicates with the cooking space 111, and the outlet 35 communicates with the condensation chamber 131, so that the cooking space 111 and the condensation chamber 131 are communicated through the diversion channel 31. Cooling water is added to the condensation chamber 131 so that the steam generated during the cooking process can flow into the condensation chamber 131 through the diversion channel 31 and condense when encountering water, thereby reducing or avoiding the outward discharge of steam. Among them, a water quantity detection structure 50 is further provided in the cooking appliance 100; the water quantity detection structure 50 can be at least one of a weight detection structure and an infrared photosensitive detection structure, etc. Among them, when the weight detection structure is used as the water quantity detection structure 50, the total weight of the condensation chamber 131 is detected to confirm the water quantity value of the condensation chamber 131, or the water level height in the current condensation chamber 131 can be obtained by weight and then the water quantity value of the condensation chamber 131 is confirmed. The infrared photosensitive detection structure generally includes a transmitter and a receiver. The transmitter emits infrared rays. When the infrared rays irradiate on the liquid surface, part of the light is reflected and part of the light is refracted. When the water level is different, the refracted and reflected light is also different, such as the light intensity and the propagation direction are different; and the receiver receives the reflected and refracted infrared rays, and the receiver can judge the current water level height according to the received infrared ray signal, so as to confirm the water quantity value of the condensation chamber 131. In addition, only one water quantity detection structure 50 can be provided, or two or more can be provided; for example, two water quantity detection structures 50 are provided for detecting at a preset minimum water level and a preset maximum water level, or two or more different water quantity detection structures 50 are provided to improve the detection accuracy of the water level.

[0097] Of course, a temperature sensor 70, a weight sensor, a water pumping structure, etc. can also be provided in the cooking appliance 100, which is not limited herein.

[0098] Since the cooking appliance 100 proposed in this application has applied all the technical solutions of the foregoing all embodiments, it has at least all the beneficial effects brought by the foregoing all embodiments, which will not be elaborated herein one by one.

[0099] Please refer to Figure 2 , in some embodiments of the present application, the cooking appliance 100 further includes an air duct 15. The air duct 15 is arranged in the condensation chamber 131. One end of the air duct 15 communicates with the diversion channel 31, and the other end extends to the bottom of the condensation chamber 131.

[0100] In this embodiment, an air guide pipe 15 is arranged in the condensation chamber 131. The air guide pipe 15 forms an air guide channel 151 that penetrates through both ends for guiding the flow of steam, such that one end of the air guide pipe 15 communicates with the diversion channel 31, and the other end extends to the bottom of the water tank 13 and is not higher than the lowest water level in the condensation chamber 131. With such an arrangement, when the cooking appliance 100 is in use, water not lower than the lowest water level is pre-added to the condensation chamber 131, so that the air outlet end of the air guide pipe 15 is submerged in the water. When cooking, the steam generated in the cooking space 111 can directly enter the water through the diversion channel 31 and the air guide pipe 15, enabling the steam to directly contact the water and cool down and condense, thereby improving the condensation efficiency of the steam.

[0101] Please refer to Figure 2 , in some embodiments of the present application, the air outlet end of the air guide pipe 15 has an outwardly expanding air guide port 153;

[0102] And / or, the air guide pipe 15 further includes an extension section that extends outward from the edge of the air outlet end of the air guide pipe 15 and is disposed opposite to the bottom wall of the condensation chamber 131.

[0103] In this embodiment, an outwardly expanding air guide port 153 is provided at the air outlet end of the air guide pipe 15 extending to the bottom of the condensation chamber 131. The air guide port 153 is generally in the shape of a flared opening, which can increase the cross-sectional area of the channel at the air outlet end of the air guide pipe 15, enable the steam discharge area to increase, and slow down the steam flow rate. When the cooking appliance 100 is in use, the water level in the condensation chamber 131 is raised to the position of the air guide pipe 15 and at least submerges the air guide port 153, so that the steam slowly discharges from the air guide port 153, reducing the steam flow rate and prolonging the heat exchange time between the steam and the cooling water; and it can increase the contact area between the steam and the water, enabling the steam to fully contact the cooling water and be quickly condensed, thereby improving the condensation efficiency of the steam.

[0104] In an embodiment of the present application, it may also be that an extension section extends outward from the edge of the air outlet of the air guide pipe 15. The extension section is disposed opposite to the bottom wall of the condensation chamber 131, and when the cooking appliance 100 is in use, the water level in the condensation chamber 131 is raised to the position of the air guide pipe 15 and at least submerges the extension section. With such an arrangement, when the steam flows out from the air guide channel 151 of the air guide pipe 15, the steam is blocked by the extension section and diffuses in all directions, preventing the steam from directly rising and discharging out of the water surface after being discharged from the air guide pipe 15. The setting of the extension section can prolong the residence time of the steam in the cooling water and the heat exchange time between the steam and the cooling water, thereby improving the condensation effect of the steam.

[0105] In some embodiments, the air guide port 153 and the extension section can be provided simultaneously, with the extension section extending outward from the edge of the air guide port 153, effectively improving the condensation effect of the steam in the condensation chamber 131.
