Description

Technical Field

[0001] This invention relates to the field of cooking technology, and in particular to a control method, control device, oven / steamer cooking appliance, and computer-readable storage medium. Background Art

[0002] Seafood, especially fish and seafood, is a staple source of oil and protein on people's tables. It is nutritious, healthy, and easy to cook, primarily through steaming and boiling. However, in multi-heat source integrated home appliances like electric ovens and steamers, single steam sources often suffer from low power and insufficient heating capacity, resulting in slow heating and turning fast steaming into slow simmering. This can cause crustaceans to become dry, tough, and sticky. Furthermore, insufficient heating during steaming can lead to inadequate deactivation of endogenous enzymes, resulting in thermal oxidation and black spots that negatively impact the appearance and taste. Summary of the Invention

[0003] The present invention provides a control method, control device, oven / steam cooking appliance, and computer-readable storage medium to solve at least one of the above-mentioned technical problems.

[0004] This invention provides a control method for a steam oven / baking appliance, the appliance comprising a cooking cavity, a steam generator, an upper heating element, and a side heating element. The control method includes:

[0006] In the first cooking stage, the steam generator, the upper heating element and the side heating element are controlled to work to heat the cooking cavity. The working percentage of the upper heating element per unit cycle is a first percentage, and the working percentage of the side heating element per unit cycle is a second percentage.

[0007] When the temperature of the cooking cavity is greater than or equal to the set temperature, the second cooking stage begins.

[0008] In the second cooking stage, the steam generator, the upper heating element, and the side heating element are controlled to maintain the temperature of the cooking cavity at the set temperature until cooking is completed.

This allows the temperature of the cooking cavity to rise rapidly to the set temperature in the first cooking stage, and maintains the temperature of the cooking cavity at the set temperature in the second cooking stage, thereby fully heating the food and meeting the cooking requirements of rapid heating and rapid steaming.

[0011] In some embodiments, the control method includes:

[0012] In at least one of the first cooking stage and the second cooking stage, the upper heating element and the side heating element are controlled to work alternately or the upper heating element and the side heating element are controlled to work alternately and simultaneously.

[0013] In some implementations, the upper limit thresholds of the first ratio, the second ratio, the third ratio, and the fourth ratio are determined by the rated power of the upper heating element and the side heating element.

[0014] In some implementations, the first ratio is 100%, and the third ratio is 60% to 100%.

[0015] In some embodiments, the second ratio is 60% to 80%, and the fourth ratio is 20% to 50%.

[0016] In some embodiments, the baking / steaming cooking appliance includes a hot air blower, and the control method includes:

[0017] During the first and second cooking stages, the hot air blower is controlled to operate to dissipate the heat from the side heating tube into the cooking cavity.

[0018] In some embodiments, the operating power of the upper heating element is less than that of the side heating element.

[0019] In some embodiments, the control method includes:

[0020] During the first cooking stage, at least one of the operating power of the steam generator, the operating power of the upper heating element, and the operating power of the side heating element is kept constant.

[0021] During the second cooking stage, at least one of the operating power of the steam generator, the operating power of the upper heating element, and the operating power of the side heating element is kept constant.

[0041] Please see Figure 1 This invention provides a control method for a baking and steaming cooking appliance 1000. Please refer to... Figure 2 and Figure 3 The baking and steaming cooking appliance 1000 includes a cooking cavity 500, a steam generator 100, an upper heating element 200, and a side heating element 300.

[0042] Control methods include:

[0043] Step S01: According to the cooking start command, control the baking and steaming cooking appliance 1000 to execute the first cooking stage and the second cooking stage in sequence.

[0044] In step S03, during the first cooking stage, the steam generator 100, the upper heating element 200, and the side heating element 300 are controlled to operate to heat the cooking cavity 500. The working percentage of the upper heating element 200 per unit cycle is the first percentage, and the working percentage of the side heating element 300 per unit cycle is the second percentage.

[0045] Step S05: When the temperature of the cooking cavity 500 is greater than or equal to the set temperature, proceed to the second cooking stage.

[0046] In step S07, during the second cooking stage, the steam generator 100, the upper heating element 200, and the side heating element 300 are controlled to maintain the temperature of the cooking cavity 500 at the set temperature until the cooking is finished. The working percentage of the upper heating element 200 per unit cycle is the third percentage, and the working percentage of the side heating element 300 per unit cycle is the fourth percentage.

[0047] Among them, the first proportion is not less than the third proportion, and the second proportion is greater than the fourth proportion.

[0048] In the control method of the above-mentioned oven-steam cooking appliance 1000, the working percentage of the upper heating tube 200 per unit cycle in the first cooking stage is not less than the working percentage of the upper heating tube 200 per unit cycle in the second cooking stage, and the working percentage of the side heating tube 300 per unit cycle in the first cooking stage is greater than the working percentage of the side heating tube 300 per unit cycle in the second cooking stage. This allows the temperature of the cooking cavity 500 to rise rapidly to the set temperature in the first cooking stage, and the temperature of the cooking cavity 500 to be maintained at the set temperature in the second cooking stage. This enables the food to be fully heated, thereby meeting the cooking requirements of rapid heating and rapid steaming.

[0049] Specifically, the Grill & Steam Cooking Appliance 1000 is a kitchen cooking appliance that integrates grilling and steaming functions, offering multiple cooking methods to meet different cooking needs. The Grill & Steam Cooking Appliance 1000 can perform high-temperature grilling and provide a humid steam environment, thereby improving cooking efficiency while satisfying the taste of the food. The Grill & Steam Cooking Appliance 1000 may include a cooking cavity 500, a steam generator 100, an upper heating element 200, and a side heating element 300.

[0050] The cooking cavity 500 is a closed or semi-closed structural component. The cooking cavity 500 contains a cooking chamber 501, within which food ingredients can be placed for cooking by the baking / steaming cooking appliance 1000. Optionally, the cooking cavity 500 can be made of metal.

[0051] The steam generator 100 is used to generate high-temperature steam and introduce it into the cooking chamber 501 to provide the steam needed for heating the food. Figure 2 In the illustrated embodiment, a steam generator 100 is located outside the cooking cavity 500. The steam generator 100 includes a water source interface, a flow channel system, and a steam outlet, wherein a heating element is provided in the flow channel system. The steam generator 100 can be connected to a water tank containing water via the water source interface and a water pump. The steam outlet of the steam generator 100 can be connected via a pipe to a nozzle located on the cooking cavity 500. Water in the water tank can be supplied to the flow channel system of the steam generator via the water source interface, so that the heating element heats the water to form high-temperature steam. The high-temperature steam can be supplied to the nozzle via the steam outlet and the pipe to input high-temperature steam into the cooking cavity 501. In one embodiment, the steam generator 100 may include a boiling water pan and a heating element. The boiling water pan may be located at the bottom of the cooking cavity 501. The heating element is located outside the cooking cavity 500. When the heating element is working, it heats the boiling water pan, causing the water in the boiling water pan to form steam. The steam is emitted from the bottom of the cooking cavity 501 to other locations in the cooking cavity 501.

[0052] The upper heating element 200 and the side heating element 300 are electric heating elements that convert electrical energy into heat energy by current flowing through a resistive material, thereby heating air to form hot air, and using the hot air and thermal radiation to heat food. Optionally, such as Figure 2 As shown, the cooking cavity 500 includes an upper plate, a bottom plate, and side plates. An upper heating element 200 may be disposed on the side of the upper plate facing the cooking cavity 501, and a side heating element 300 may be disposed on the side of the side plate facing the cooking cavity 501. In one embodiment, the upper heating element 200 is disposed on the side of the upper plate away from the cooking cavity 501. The upper heating element 200 can heat the food placed inside the cooking cavity 501 by heating the upper plate. In one embodiment, the side heating element 300 is disposed on the side of the side plate away from the cooking cavity 501. The side heating element 300 can heat the food placed inside the cooking cavity 501 by heating the side plate.

[0053] In related technologies, oven-steam cooking appliances can simultaneously bake and steam food. Existing oven-steam cooking appliances bake and steam food by operating all heating elements and the steam generator at full capacity. However, operating all heating elements and the steam generator at full capacity is easily limited by the overall power load limit of the appliance and can also lead to energy waste. In particular, during the cooking process, there is no design for the different installation positions of the heating elements and the working ratio of the heating elements in different positions. Some of the heat generated by the heating elements may not be effectively applied to the food, resulting in energy waste.

[0054] In this embodiment of the invention, the oven / steam cooking appliance 1000 includes an upper heating element 200 and a side heating element 300 disposed at different positions. The oven / steam cooking appliance 1000 also includes a control device 2, which is electrically connected to the upper heating element 200 and the side heating element 300.

[0055] After receiving the cooking start command, the control device 2 can control the steam generator 100 to work continuously to provide a humid cooking environment to ensure the taste of the food, and control the upper heating element 200 and / or the side heating element 300 to work intermittently until the temperature of the cooking cavity 500 is greater than or equal to the set temperature. When the temperature of the cooking cavity 500 is greater than or equal to the set temperature, the control device 2 can control the steam generator 100 to continue working continuously to provide a humid cooking environment to ensure the taste of the food, and control the upper heating element 200 and / or the side heating element 300 to work intermittently until the cooking is finished.

[0056] It should be noted that intermittent operation refers to the electrical components working or resting according to a set working percentage within each unit cycle. In one embodiment, the duration of one unit cycle is 60 seconds (s). In the first cooking stage, the working percentage of the upper heating element 200 per unit cycle is a first percentage, and the working percentage of the side heating element 300 per unit cycle is a second percentage. If the first percentage is 80% and the second percentage is 60%, then the control device 2 can control the upper heating element 200 to work for 48 seconds and rest for 12 seconds within one unit cycle. Multiple unit cycles in the first cooking stage constitute the intermittent operation of the upper heating element 200; the control device 2 can control the side heating element 300 to work for 36 seconds and rest for 24 seconds within one unit cycle. Multiple unit cycles in the first cooking stage constitute the intermittent operation of the side heating element 300.

[0057] It should be noted that when the working percentage of an electrical component is set to 100%, the electrical component will not work intermittently (it will work continuously).

[0058] It should be understood that the upper heating element 200 is located above the cooking cavity 501, and the side heating element 300 is located to the side of the cooking cavity 501. The upper heating element 200 and the side heating element 300 in different positions can transfer heat into the cooking cavity 501 from different directions, which helps to achieve a more uniform heat distribution and thus improve the heating effect of the food.

[0059] It should be understood that during the cooking process, controlling the intermittent operation of the upper heating element 200 and / or the side heating element 300 can reduce the probability of simultaneously turning on the steam generator 100, the upper heating element 200, and the side heating element 300. This can reduce the situation where the steam generator 100, the upper heating element 200, and the side heating element 300 are turned on at the same time, thereby avoiding the limitation of the upper limit of the overall power load. On this basis, first controlling the upper heating element 200 to operate at a larger first ratio and the side heating element 300 to operate at a larger second ratio can enable the temperature of the cooking cavity 500 to rise rapidly in the first cooking stage. Then controlling the upper heating element 200 to operate at a smaller or unchanged third ratio and the side heating element 300 to operate at a smaller fourth ratio can maintain the temperature of the cooking cavity 500 at the set temperature in the second cooking stage, thereby fully heating the food and meeting the cooking requirements of rapid heating and rapid steaming.

[0060] It should be noted that the first ratio refers to the percentage of operation of the upper heating element 200 per unit cycle in the first cooking stage; the second ratio refers to the percentage of operation of the side heating element 300 per unit cycle in the first cooking stage; the third ratio refers to the percentage of operation of the upper heating element 200 per unit cycle in the second cooking stage; and the fourth ratio refers to the percentage of operation of the side heating element 300 per unit cycle in the second cooking stage. The percentage of operation per unit cycle refers to the ratio of the working time to the unit cycle duration within one unit cycle. Optionally, the unit cycle duration can be 30 seconds (s) or 60 seconds (s). In one embodiment, the unit cycle duration is 60 seconds, and the first ratio is 80%, then in the first cooking stage, the upper heating element 200 operates for 48 seconds within each 60-second unit cycle, that is, in the first cooking stage, the upper heating element 200 operates for 48 seconds every 12-second interval (rest).

[0061] Optionally, the set temperature can be less than or equal to the cooking temperature. Different ingredients require different temperatures during cooking, and different cooking needs (e.g., a firm, chewy, or tender texture) necessitate different cooking temperatures. The cooking temperature can refer to a temperature determined based on different ingredients and cooking needs. In one example, for steaming fish and seafood, the set temperature is between 120℃ and 170℃. In another example, for 500g of fresh, live shrimp, the cooking temperature is 130℃, and the set temperature is 120℃.

[0062] It should be noted that the first cooking stage is the heating stage of the cooking process. During this stage, the oven-steamer appliance 1000 needs to quickly raise the temperature of the cooking cavity 500 to the set temperature to avoid prolonged cooking and poor cooking results. The second cooking stage is the temperature maintenance stage. During this stage, the oven-steamer appliance 1000 needs to maintain the temperature of the cooking cavity 500 at the set temperature to avoid overheating the food.

[0063] It should be noted that the steam generator 100 operates continuously during both the first and second cooking stages to provide a humid and hot cooking environment to ensure the texture of the ingredients.

[0064] In some implementations, the control method includes:

[0065] In at least one of the first cooking stage and the second cooking stage, the upper heating element 200 and the side heating element 300 are controlled to work alternately or to work alternately and simultaneously.

[0066] In the above embodiments, during the cooking process, the upper heating element 200 and the side heating element 300 can work alternately, or work alternately and simultaneously, which can further reduce the situation where the steam generator 100, the upper heating element 200 and the side heating element 300 are turned on at the same time, thereby further avoiding the limitation of the upper limit of the overall power load.

[0067] Specifically, in one embodiment, during at least one of the first cooking stage and the second cooking stage, the control device 2 can control the upper heating tube 200 and the side heating tube 300 to work alternately, that is, when the upper heating tube 200 is working, the side heating tube 300 is resting, and when the side heating tube 300 is working, the upper heating tube 200 is resting.

[0068] In one embodiment, during at least one of the first cooking stage and the second cooking stage, the control device 2 can control the upper heating element 200 and the side heating element 300 to work alternately and simultaneously, that is, to control the upper heating element 200 and the side heating element 300 to work alternately during a part of the cooking stage, and to control the upper heating element 200 and the side heating element 300 to work simultaneously during another part of the cooking stage.

[0069] It should be understood that the alternating operation of the upper heating tube 200 and the side heating tube 300 provides more precise control over their working and rest times. Specifically, within each unit cycle, the rest time of one of them is synchronized with at least a portion of the working time of the other. This ensures, to a certain extent, that the simultaneous operation of the steam generator 100, the upper heating tube 200, and the side heating tube 300 can be guaranteed, further avoiding the limitation imposed by the overall power load limit.

[0070] In one embodiment, if the sum of the first ratio and the second ratio is less than or equal to 100%, during the first cooking stage, the control device 2 controls the upper heating element 200 and the side heating element 300 to work alternately. That is, in each unit cycle, one of the upper heating element 200 and the side heating element 300 is first controlled to work according to the first ratio or the second ratio, and then the other of the upper heating element 200 and the side heating element 300 is controlled to work according to the first ratio or the second ratio. Multiple unit cycles of the first cooking stage can constitute the alternating operation of the upper heating element 200 and the side heating element 300.

[0071] In one embodiment, if the sum of the first ratio and the second ratio is greater than 100%, during the first cooking stage, the control device 2 controls the upper heating element 200 and the side heating element 300 to work alternately and simultaneously. Specifically, in each unit cycle, the overlapping portion of the working time of the upper heating element 200 and the side heating element 300 is simultaneous operation, and the staggered portion is staggered operation. In multiple unit cycles, multiple staggered operations constitute the alternating operation of the upper heating element 200 and the side heating element 300 during the first cooking stage.

[0072] In one embodiment, if the sum of the third and fourth ratios is less than or equal to 100%, during the second cooking stage, the control device 2 controls the upper heating element 200 and the side heating element 300 to work alternately. That is, in each unit cycle, one of the upper heating element 200 and the side heating element 300 is first controlled to work at the third or fourth ratio, and then the other of the upper heating element 200 and the side heating element 300 is controlled to work at the third or fourth ratio. Multiple unit cycles of the second cooking stage can constitute the alternating operation of the upper heating element 200 and the side heating element 300.

[0073] In one embodiment, if the sum of the third and fourth ratios is greater than 100%, during the second cooking stage, the control device 2 controls the upper heating element 200 and the side heating element 300 to work alternately and simultaneously. Specifically, in each unit cycle, the overlapping portion of the working time of the upper heating element 200 and the side heating element 300 is simultaneous operation, and the staggered portion is staggered operation. Over multiple unit cycles, multiple staggered operations constitute the alternating operation of the upper heating element 200 and the side heating element 300 during the second cooking stage. In some embodiments, the upper limit thresholds of the first, second, third, and fourth ratios are determined by the rated power of the upper heating element 200 and the side heating element 300.

[0074] In the above embodiments, the upper limit thresholds of the first ratio, the second ratio, the third ratio and the fourth ratio are determined by the rated power of the upper heating tube 200 and the side heating tube 300, which can reduce unnecessary energy waste and lower safety risks to a certain extent.

[0075] Specifically, the control device 2 can control the heating process by adjusting the working time of the heating tube, that is, by adjusting the size of the first ratio, the second ratio, the third ratio and the fourth ratio, so as to ensure rapid heating to a certain extent while avoiding overheating of food and resulting in poor cooking effect.

[0076] In one embodiment, rated power refers to the maximum or limited power at which the equipment or electrical component can operate stably and safely for a long period under normal operating conditions. A higher rated power results in stronger heat output and generates more heat per unit time. To avoid unnecessary energy waste or high safety risks caused by the oven / steamer appliance 1000 operating under high load, in this embodiment of the invention, the upper limit thresholds of the first, second, third, and fourth ratios are determined by the rated power of the upper heating element 200 and the side heating element 300.

[0077] Optionally, the upper limit thresholds of the first ratio, the second ratio, the third ratio, and the fourth ratio can be determined by experimental testing or simulation analysis based on the rated power of the upper heating tube 200 and the side heating tube 300.

[0078] In some implementations, the first proportion is 100%, and the third proportion is 60% to 100%.

[0079] In the above embodiments, the first ratio is 100% and the third ratio is 60% to 100%. In the first cooking stage, the heating element 200 can be controlled to rapidly raise the temperature of the cooking cavity 500, and in the second cooking stage, the heating element 200 can be controlled to maintain the temperature of the cooking cavity 500 at the set temperature, so as to fully heat the food and meet the cooking requirements of rapid heating and fast steaming.

[0080] Specifically, the first ratio is 100%, meaning that the upper heating element 200 operates continuously (without interruption) throughout the first cooking stage. The upper heating element 200 reaches its maximum operating percentage during the first cooking stage, thereby enabling the temperature of the cooking cavity 500 to rise rapidly. Optionally, the operating power of the upper heating element 200 can be its maximum power.

[0081] The third ratio is 60% to 100%. The working ratio of the upper heating element 200 in the second cooking stage decreases or remains unchanged, which can avoid overheating the food to a certain extent, while keeping the temperature of the cooking cavity 500 at the set temperature.

[0082] In some examples, the third percentage can be equal to 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 100%, or other values ​​between 60% and 100%.

[0083] In some implementations, the second proportion is 60% to 80%, and the fourth proportion is 20% to 50%.

[0084] In the above embodiments, the second ratio is 60% to 80%, and the fourth ratio is 20% to 50%. In the first cooking stage, the control side heating tube 300 can rapidly raise the temperature of the cooking cavity 500, and in the second cooking stage, the control side heating tube 300 can maintain the temperature of the cooking cavity 500 at the set temperature, thereby fully heating the food and meeting the cooking requirements of rapid heating and fast steaming.

[0085] Specifically, the second ratio is 60% to 80%, where the side heating element 300 operates at a higher rate during the first cooking stage, allowing the temperature of the cooking cavity 500 to rise rapidly. The fourth ratio is 20% to 50%, where the side heating element 300 operates at a lower rate during the second cooking stage, thus preventing overheating of the food to some extent and maintaining the temperature of the cooking cavity 500 at the set temperature. Optionally, the operating power of the side heating element 300 can be its maximum power.

[0086] In some examples, the second percentage can be equal to 60%, 63%, 65%, 68%, 70%, 73%, 75%, 78%, 80%, or other values ​​between 60% and 80%.

[0087] In some examples, the fourth percentage can be equal to 20%, 25%, 30%, 35%, 40%, 45%, 50%, or other values ​​between 20% and 50%.

[0088] In some implementations, please refer to Figure 2 The 1000 oven and steam cooking appliance includes a 400 hot air blower. Control method:

[0089] In the first and second cooking stages, the hot air blower 400 is controlled to operate to blow the heat from the side heating tube 300 into the cooking cavity 500.

[0090] In the above embodiments, the hot air blower 400 can blow the heat from the side heating tube 300 into the cooking cavity 501, thereby heating the food more evenly and improving the cooking effect.

[0091] Specifically, the hot air blower 400 is a device used to dissipate heat from the side heating element 300 into the cooking cavity 500. During the first and second cooking stages, the hot air blower 400 can generate airflow to evenly distribute the hot air around the side heating element 300 throughout the entire cooking cavity 500. It can be understood that when the hot air blower 400 is operating, it can also drive airflow around the upper heating element 200, thereby dissipating heat from the upper heating element 200 into the cooking cavity 500.

[0092] In one embodiment, a hot air blower 400 is located on the side of the side heating pipe 300 near the cooking cavity 501. The hot air blower 400 can draw in hot air near the side heating pipe 300 and blow it into the cooking cavity 500.

[0093] Optionally, in one embodiment, the hot air blower 400 operates at a first speed during the first cooking stage and at a second speed during the second cooking stage. The first speed is greater than the second speed, which allows the heat from the side heating tube 300 to be dissipated into the cooking cavity 501 more quickly during the first cooking stage, further improving the heating efficiency of the cooking cavity 500, while reducing energy consumption to some extent during the second cooking stage.

[0094] In some embodiments, the operating power of the upper heating element 200 is less than that of the side heating element 300.

[0095] In the above embodiments, the working power of the upper heating tube 200 is less than that of the side heating tube 300, which is conducive to achieving a more flexible working ratio scheme, thereby controlling energy consumption and avoiding energy waste to a certain extent.

[0096] Specifically, the operating power of the upper heating element 200 refers to the actual electrical power consumed by the upper heating element 200 during its operation. The operating power of the side heating element 300 refers to the actual electrical power consumed by the side heating element 300 during its operation. The upper heating element 200 has a lower operating power and relatively lower energy consumption, while the side heating element 300 has a higher operating power and relatively higher energy consumption. Heating the cooking cavity 500 using both the upper heating element 200 and the side heating element 300 allows for a more flexible operating ratio, thereby controlling energy consumption and avoiding energy waste to some extent.

[0097] In some implementations, the control method includes:

[0098] Step S13, in the first cooking stage, at least one of the operating power of the steam generator 100, the operating power of the upper heating element 200, and the operating power of the side heating element 300 is kept constant;

[0099] In step S15, during the second cooking stage, at least one of the operating power of the steam generator 100, the operating power of the upper heating element 200, and the operating power of the side heating element 300 is kept constant.

[0100] The above embodiments can simplify power adjustment during the cooking process to a certain extent and reduce the control complexity of the baking and steaming cooking appliance 1000 to a certain extent.

[0101] Optionally, in one embodiment, the steam generator 100, the upper heating element 200, and the side heating element 300 operate at a higher power during the first cooking stage than during the second cooking stage.

[0102] In one embodiment, the steam generator 100 has an operating power of 1200W or more and 1800W or less, the upper heating element 200 has an operating power of 400W or more and 800W or less, and the side heating element 300 has an operating power of 1500W or more and 1800W or less.

[0103] In one example, the duration of a unit cycle is 60 seconds, the first proportion is 100%, the second proportion is 60%, the third proportion is 60%, and the fourth proportion is 20%. The first cooking stage and the second cooking stage may include cooking times consisting of multiple individual cycles.

[0104] In the first cooking stage, the steam generator 100 operates at a power of 1500W, the upper heating element 200 operates at a power of 700W, and the side heating element 300 operates at a power of 1700W. In the second cooking stage, the steam generator 100 operates at a power of 1300W, the upper heating element 200 operates at a power of 500W, and the side heating element 300 operates at a power of 1500W.

[0105] In the first cooking stage, the steam generator 100, upper heating element 200, and side heating element 300 are controlled to operate to heat the cooking cavity 500. The steam generator 100 operates continuously with a constant power of 1500W. The upper heating element 200 operates continuously with a constant power of 700W. The side heating element 300 operates for 36 seconds every 24 seconds within one unit cycle, with a constant power of 1700W.

[0106] In the second cooking stage, the steam generator 100, upper heating element 200, and side heating element 300 are controlled to maintain the temperature of the cooking cavity 500 at the set temperature. The steam generator 100 operates continuously with a constant power of 1300W. The upper heating element 200 operates for 36 seconds every 24 seconds within a unit cycle, with a constant power of 500W. The side heating element 300 operates for 12 seconds every 48 seconds within a unit cycle, with a constant power of 1500W.

[0107] At least one of the operating power of the steam generator 100, the operating power of the upper heating element 200, and the operating power of the side heating element 300 is kept constant. In one embodiment, the operating power of the steam generator 100, the operating power of the upper heating element 200, or the operating power of the side heating element 300 is kept constant. In another embodiment, any two or three of the operating power of the steam generator 100, the operating power of the upper heating element 200, and the operating power of the side heating element 300 are kept constant.

[0108] Please refer to Figure 3 The control device 2 of a baking and steaming cooking appliance 1000 according to an embodiment of the present invention includes a processor 22 and a memory 21. The memory 21 stores a computer program. When the computer program is executed by the processor 22, it implements the steps of the control method of any of the above embodiments.

[0109] Specifically, the control device 2 is electrically connected to the steam generator 100, the upper heating element 200, the side heating element 300, and the hot air blower 400. The control device 2 can control the steam generator 100, the upper heating element 200, and the side heating element 300 to operate in sequence to execute the first cooking stage and the second cooking stage.

[0110] Please refer to Figure 3 The present invention provides a baking and steaming cooking appliance 1000, which includes the control device 2 described in the above embodiment.

[0111] Specifically, the Oven-Steam Cooking Appliance 1000 is a kitchen cooking device that integrates baking and steaming functions, providing multiple cooking methods to meet different cooking needs. The Oven-Steam Cooking Appliance 1000 can perform high-temperature baking and provide a humid steaming environment, thereby improving cooking efficiency while satisfying the taste of the ingredients. The Oven-Steam Cooking Appliance 1000 may include, but is not limited to, a cooking cavity 500, a steam generator 100, an upper heating element 200, and a side heating element 300.

[0112] In some implementations, please refer to Figure 2 The baking and steaming cooking appliance 1000 includes a cooking cavity 500 and a liquid receiving box 600.

The liquid receiving box 600 is located outside the cooking cavity 500 and is connected to the drain hole 502.

[0113] In the above embodiments, the drain hole 502 and the liquid receiving box 600 can promptly drain the condensate in the cooking cavity 501 out of the cooking cavity 500, thereby avoiding the accumulation of condensate in the cooking cavity 500 to a certain extent and affecting the cooking effect and cooking efficiency.

[0114] Specifically, the cooking cavity 500 is a closed or semi-closed structure. Inside the cooking cavity 500 is a cooking chamber 501, where food ingredients can be placed for cooking by the baking / steaming equipment. During cooking, water vapor inside the cooking chamber 501 condenses upon contact with the cooler surface of the food ingredients or the surface of the cooking cavity 500. A drain hole 502 is located at the bottom of the cooking cavity 501. The condensate flows naturally to the drain hole 502 under gravity and is discharged outside the cooking cavity 500 to be collected by the liquid collection box 600.

[0115] Optionally, the number, size, and shape of the drain holes 502 can be selected according to the volume of the oven / steamer cooking appliance 1000, drainage requirements, etc., and the present invention does not impose specific limitations on this.

[0116] The present invention provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor 22, implements the steps of the control method of any of the above embodiments.

The working percentage of the upper heating element 200 per unit cycle is the first percentage, and the working percentage of the side heating element 300 per unit cycle is the second percentage.

[0120] Step S05: When the temperature of the cooking cavity 500 is greater than or equal to the set temperature, proceed to the second cooking stage.

[0121] In step S07, during the second cooking stage, the steam generator 100, the upper heating element 200, and the side heating element 300 are controlled to maintain the temperature of the cooking cavity 500 at the set temperature until the cooking is finished. The working percentage of the upper heating element 200 per unit cycle is the third percentage, and the working percentage of the side heating element 300 per unit cycle is the fourth percentage.

[0122] Among them, the first proportion is not less than the third proportion, and the second proportion is greater than the fourth proportion.
