Description
Technical Field
[0001] This application relates to the field of smart home appliances, and in particular to a control method for a smart steam oven and a smart steam oven. Background Technology
[0002] In existing technologies, steam ovens generally use air pumps or fans for forced ventilation to achieve dehumidification. This method involves introducing dry external air and expelling hot, humid air from the cavity. However, this approach inevitably leads to drastic fluctuations in temperature and humidity within the cavity. The high-speed, cold, dry airflow can cause excessive moisture loss from the food's surface, while significant heat loss may result in insufficient internal cooking, ultimately affecting the cooking outcome. Furthermore, this dehumidification device has a limited function, operating only during periods when humidity reduction is needed, and cannot provide more flexible environmental control throughout the entire cooking process.
[0003] There is currently no effective solution to the problems that the dehumidification process affects the cooking effect and that the dehumidification device has limited functionality in related technologies. Summary of the Invention

[0017] When the relative humidity value is less than or equal to the corresponding first parameter threshold and the temperature value is greater than or equal to the corresponding third parameter threshold, the condenser plate is controlled to enter the auxiliary heating mode.
[0018] In some embodiments, controlling the condenser plate to enter the auxiliary heating mode includes:
[0019] In the auxiliary heating mode, the condenser plate is controlled to be heated to a first target temperature; the first target temperature is used to form a local micro-heat zone in the intelligent steam oven cavity.
[0020] In some embodiments, the intelligent steam oven cavity is equipped with a spice container; controlling the condenser plate to enter the auxiliary heating mode includes:

[0023] In the auxiliary heating mode, the condenser plate is heated to a third target temperature; the third target temperature is used to soften the oil stains inside the intelligent steam oven cavity.
[0024] In some embodiments, the method further includes:
[0025] When the cooking process in the smart steam oven ends, it is determined whether the relative humidity value inside the smart steam oven cavity is greater than a preset safety threshold.
[0026] If the relative humidity value is greater than the preset safety threshold, the condenser plate is controlled to operate at maximum cooling power.
[0027] When the relative humidity value is less than the preset safety threshold, a safety door opening prompt is generated.
[0028] Secondly, this embodiment provides an intelligent steam oven, including a controller, which executes the steps of the control method for the intelligent steam oven described in the first aspect.

[0040] The method embodiments provided in this example can be executed on a terminal, computer, or similar computing device. For example, it can run on a terminal.

[0043] This embodiment provides a control method for an intelligent steam oven, wherein a condensation plate is provided inside the intelligent steam oven cavity. Figure 2 This is a flowchart of the control method for the intelligent steam oven in this embodiment, as shown below. Figure 2 As shown, the process includes the following steps:
[0044] Step S210: Real-time acquisition of environmental parameters inside the intelligent steam oven cavity; environmental parameters include relative humidity and temperature.
[0045] Step S220: Determine the parameter thresholds corresponding to the environmental parameters; wherein, the relative humidity value corresponds to the first parameter threshold; and the temperature value corresponds to the second and third parameter thresholds.
[0046] Step S230: Compare the environmental parameters with the corresponding parameter thresholds, and control the condenser plate to start the corresponding target mode based on the comparison result; the target modes include cooling and dehumidification mode and auxiliary heating mode.
[0047] Specifically, various sensors within the intelligent steam oven cavity collect environmental parameters in real time. These include a humidity sensor to collect the relative humidity value inside the cavity, and a temperature sensor to collect the temperature value.
[0048] It should be noted that different environmental parameters have corresponding threshold values. The relative humidity value corresponds to the first threshold value, which is a preset target humidity range (e.g., 70%~85%). This first threshold value can be dynamically adjusted based on the cooking mode (e.g., steaming, baking, steam-baking combination, sous-vide, etc.), ingredient type, or cooking stage. For example, when steaming seafood, a higher humidity threshold can be set to maintain its tenderness; while when baking bread or other baked goods, a relatively lower humidity threshold can be used to ensure a crispy surface. Furthermore, the temperature value has corresponding second and third threshold values, which are the preset minimum temperature and target cavity temperature, respectively. These second and third threshold values can also be dynamically adjusted based on the cooking mode, ingredient type, or cooking stage to adapt to diverse cooking needs.
[0049] Furthermore, during cooking, the condenser plate is intelligently controlled based on real-time monitored internal environmental parameters. When the relative humidity value is greater than the corresponding first parameter threshold and the temperature value is greater than the corresponding second parameter threshold, the condenser plate is controlled to start the cooling and dehumidification mode; when the relative humidity value is less than or equal to the corresponding first parameter threshold and the temperature value is greater than or equal to the corresponding third parameter threshold, the condenser plate is controlled to switch to auxiliary heating mode.
[0050] Understandably, the condenser plate is typically located in a specific area within the cavity of a smart steam oven (such as the left or right side walls or the top). Its material is preferably stainless steel, which offers excellent thermal performance and is easy to clean, or aluminum alloy with an oil-resistant coating. The condenser plate features bidirectional temperature control, and its temperature control unit preferably employs a reversible Peltier module to flexibly adjust the surface temperature of the condenser plate according to control commands, enabling flexible switching of the condenser plate's operating modes. In different operating modes of the condenser plate, the power can be dynamically adjusted based on the cooking mode, temperature and humidity sensor data, and / or preset curves (used to define the ideal humidity / temperature change trajectory over time).
[0051] Furthermore, the system monitors the humidity changes within the intelligent steam oven cavity in real time, specifically the rate of change of relative humidity per unit time, and promptly switches the condenser plate's operating mode based on these trends. For example, when the relative humidity level inside the cavity rapidly approaches the target value, the cooling power is reduced in advance; when a rapid increase in humidity is detected that may exceed the set range, the cooling function is activated in advance to suppress it. Based on this control mechanism, unnecessary cooling or heating actions are effectively reduced, thereby achieving precise humidity control while significantly reducing energy consumption and avoiding drastic fluctuations in the cavity environment.
[0052] Therefore, a condenser plate with bidirectional temperature control is integrated into the cavity of the intelligent steam oven. During the dehumidification phase, it rapidly condenses water vapor through cooling, and during the non-dehumidification phase, it switches to auxiliary heating, achieving multiple uses in one plate and flexibly adapting to diverse cooking needs. This not only ensures efficient dehumidification performance, avoiding any impact on cooking results, but also significantly improves the utilization rate of the condenser plate, while effectively preventing condensation and oil adhesion problems caused by excessively low plate surface temperature during the non-dehumidification phase.
[0053] In existing technologies, steam ovens generally use air pumps or fans for forced ventilation to achieve dehumidification. This method involves introducing dry external air and expelling hot, humid air from the cavity. However, this approach inevitably leads to drastic fluctuations in temperature and humidity within the cavity. The high-speed, cold, dry airflow can cause excessive moisture loss from the food's surface, while significant heat loss may result in insufficient internal cooking, ultimately affecting the cooking outcome. Furthermore, this dehumidification device has a limited function, operating only during periods when humidity reduction is needed, and cannot provide more flexible environmental control throughout the entire cooking process.
[0054] Compared to existing technologies, this application collects environmental parameters within the intelligent steam oven cavity in real time. These parameters include relative humidity and temperature. It then determines parameter thresholds corresponding to these real-time environmental parameters, with relative humidity corresponding to a first threshold and temperature corresponding to a second and third threshold. The real-time environmental parameters are compared with their corresponding thresholds, and based on the comparison results, the condenser plate is controlled to activate the corresponding target mode. The target modes include a cooling / dehumidification mode and an auxiliary heating mode. Based on this, by integrating a condenser plate with bidirectional temperature control into the intelligent steam oven cavity, it can rapidly condense water vapor during the dehumidification phase and switch to auxiliary heating during the non-dehumidification phase. This allows for automatic switching between different operating modes according to cooking needs, solving the problem of dehumidification affecting cooking results and the limitation of single-function dehumidification devices. It avoids the impact of dehumidification on cooking performance and achieves bidirectional adjustment of the cavity environment by a single component, improving equipment utilization and control flexibility.
[0055] In some embodiments, step S230, which compares the environmental parameters with corresponding parameter thresholds and controls the condenser plate to start the corresponding target mode based on the comparison result, includes the following steps:
[0056] When the relative humidity value is greater than the corresponding first parameter threshold and the temperature value is greater than the corresponding second parameter threshold, the condenser plate is controlled to enter the cooling and dehumidification mode.
[0057] Specifically, the relative humidity value corresponds to a first parameter threshold, which is a preset target humidity range (e.g., 70%~85%). The first parameter threshold can be dynamically adjusted according to the cooking mode, food type, or cooking stage. In addition, the temperature value has a corresponding second parameter threshold, which is a preset minimum temperature value used to determine whether to start the dehumidification process.
[0058] When the relative humidity value exceeds the corresponding first parameter threshold and the temperature value exceeds the corresponding second parameter threshold, the condenser plate is controlled to activate the cooling and dehumidification mode. In this mode, the temperature of the condenser plate decreases, causing water vapor within the chamber to condense into liquid. The condensate flows along the plate surface into the collection tank and is then discharged into the wastewater tank via a guide pipe. When the wastewater tank's full water sensor detects that the tank is full, it will automatically prompt the user to empty it promptly to ensure stable operation thereafter.
[0059] In this way, active cooling and dehumidification via the condenser plate eliminates the need to introduce external cold air or forcibly expel air from the cavity, thus completely avoiding drastic temperature and humidity fluctuations caused by forced ventilation. This ensures a stable internal environment, providing uniform and controllable cooking conditions for food. Simultaneously, by avoiding the impact of high-speed airflow and preventing significant heat loss, the quality and taste of food are effectively preserved.
[0060] In some embodiments, the control method for the above-mentioned intelligent steam oven further includes the following steps:
[0061] Based on the collected relative humidity and temperature values, determine the corresponding air dew point temperature;
[0062] In cooling and dehumidification mode, the surface temperature of the condenser plate is controlled to be lower than the air dew point temperature.
[0063] Specifically, based on the relative humidity and temperature values inside the intelligent steam oven cavity, the current air dew point temperature (e.g., 3~8℃) is calculated. The air dew point temperature refers to the critical temperature at which water vapor in the air reaches saturation and begins to condense into liquid water under the current air pressure. This temperature provides a crucial data benchmark for subsequent condensation dehumidification.
[0064] In cooling and dehumidifying mode, the temperature control unit of the condenser plate lowers the surface temperature of the condenser plate to below the current air dew point temperature. When the air inside the steam oven cavity comes into contact with the low-temperature plate surface, the water vapor it contains will quickly condense into liquid water droplets because the temperature is lower than its dew point, thus achieving a highly efficient and precise dehumidification effect.
[0065] It should be noted that the system can dynamically adjust the duration for which the surface temperature of the condenser plate remains below the air dew point temperature based on the deviation between the real-time monitored relative humidity value inside the cavity and the target humidity range. This allows for precise control of the condensation dehumidification capacity, ensuring that the humidity inside the cavity quickly approaches and stabilizes within the target range. The setting of the target humidity range is related to several key factors, including but not limited to the cooking mode, food type, and cooking stage.
[0066] For example, in steaming mode, a higher target humidity range is maintained to achieve efficient heat transfer through a saturated steam environment, ensuring that food cooks quickly and evenly; in baking mode, a relatively lower target humidity range is usually used to avoid excessive loss of moisture from the food surface, which would affect the taste of the finished product.
[0067] This embodiment utilizes real-time calculated air dew point temperature to precisely control the dehumidification process, while ensuring that the humidity inside the cavity is stably controlled within the target range, thereby providing a suitable cooking environment and improving the cooking effect of food.
[0068] In some embodiments, the control method for the above-mentioned intelligent steam oven further includes the following steps:
[0069] In cooling and dehumidification mode, the cooling power is adjusted in real time based on the rate of humidity decrease in the intelligent steam oven cavity and the surface temperature of the condenser plate.
[0070] Specifically, when the steam oven operates in cooling and dehumidification mode, it continuously monitors the rate of humidity decrease in the cavity and the real-time surface temperature of the condenser plate. The rate of humidity decrease directly reflects the effectiveness of the current dehumidification process, while the surface temperature of the condenser plate is directly related to the energy consumption of cooling and dehumidification.
[0071] Based on the aforementioned real-time data, the cooling power of the condenser plate temperature control unit is dynamically adjusted using pulse width modulation (PWM) or proportional-integral-derivative (PID) control algorithms.
[0072] For example, in baking mode, the system presets a target humidity of 50%. In the early stages of cooking, when the real-time relative humidity inside the cavity is 70%, there is a large deviation from the target value. At this time, the system operates with a higher cooling power to achieve rapid dehumidification. In the middle stages of cooking, when the relative humidity value is detected to be close to the target humidity value, the cooling power will be reduced to allow the humidity to smoothly transition to the target range. In the later stages of cooking, when the humidity is stable near the target humidity, only the minimum power required to maintain it is applied. This not only condenses the newly generated water vapor during cooking in a timely manner, but also effectively avoids moisture loss from the surface of the food due to excessive dehumidification.
[0073] This embodiment ensures that the humidity inside the cavity can be quickly and stably controlled within a preset target range, avoiding continuous maximum power cooling and significantly reducing system energy consumption. Simultaneously, by utilizing flexibly adjustable cooling power, excessive moisture loss from food due to over- or overly rapid dehumidification is prevented, effectively avoiding the problem of dry and hard food texture.
[0074] In some embodiments, step S230, which compares the environmental parameters with corresponding parameter thresholds and controls the condenser plate to start the corresponding target mode based on the comparison result, includes the following steps:
[0075] When the relative humidity value is less than or equal to the corresponding first parameter threshold and the temperature value is greater than or equal to the corresponding third parameter threshold, the condenser plate is controlled to enter the auxiliary heating mode.
[0076] Specifically, the relative humidity value corresponds to the first parameter threshold, which is a preset target humidity range (e.g., 70%~85%). The first parameter threshold can be dynamically adjusted according to the cooking mode, ingredient type, or cooking stage. In addition, the temperature value has a corresponding third parameter threshold, which is a preset target cavity temperature used to determine whether to start the heating process.
[0077] When the relative humidity value is detected to be less than or equal to the corresponding first parameter threshold and the temperature value is greater than or equal to the corresponding third parameter threshold, the temperature control unit driving the condenser plate will be switched to the heating function so that the condenser plate can start the auxiliary heating mode.
[0078] The specific execution strategy of the auxiliary heating mode is related to the cooking stage, cooking mode, or other functional requirements. For example, in the early stage of cooking, in order to accelerate local heating and shorten the preheating time, the condenser plate can be controlled to heat up rapidly, forming a local micro-heat zone in the intelligent steam oven cavity; when the aroma or smoking function is activated, the condenser plate can be controlled to heat up, so as to promote the continuous release of aroma molecules by the spices placed in the spice container, ensuring that the food absorbs the aromatic substances evenly; when baking at high temperature, the auxiliary heating of the condenser plate can supplement the top heat source, ensuring that the cavity temperature is maintained stably at the set high temperature; in the self-cleaning mode, the condenser plate will be controlled to enter a high-temperature working state, and its surface temperature will rise to a specific range (such as above 70°C) by heating, so that the oil stains attached to the surface of the condenser plate will soften, and the food residue will be carbonized and loosened under continuous high temperature. This process can be further combined with the steam flushing function, thereby greatly simplifying the cleaning process.
[0079] This embodiment enables the condenser plate to intelligently switch between cooling and dehumidification and auxiliary heating modes based on real-time changes in the cavity environment parameters, breaking through the single-function limitation of the condenser device in the steam oven, while significantly improving the diversity of cooking effects and ease of use.
[0080] In some embodiments, controlling the condenser plate to enter auxiliary heating mode includes the following steps:
[0081] In auxiliary heating mode, the condenser plate is heated to the first target temperature; the first target temperature is used to form a local micro-heat zone in the intelligent steam oven cavity.
[0082] In this embodiment, when the steam oven operates in auxiliary heating mode, the condenser plate is heated to a preset first target temperature (e.g., 40~60℃). This first target temperature aims to create a stable local micro-heat zone within the intelligent steam oven cavity through the heating function of the condenser plate, thereby achieving precise regulation of the internal thermal environment.
[0083] For example, in the early stages of cooking, the auxiliary heating mode is activated, and the local micro-heated area it forms works in conjunction with the main heating system of the steam oven to effectively accelerate the local heating inside the cavity, thereby shortening the preheating time and improving cooking efficiency. During long-term low-humidity baking or food warming, the auxiliary heating mode provides weak supplemental heating to accurately compensate for some of the heat loss, thereby stabilizing the temperature field and avoiding temperature fluctuations from affecting the cooking effect.
[0084] This embodiment utilizes the heating function of the condenser plate to enhance the cavity environment control capability of the steam oven, providing a precise heat source for different cooking scenarios, while significantly improving the controllability and stability of the cooking process.
[0085] In some embodiments, the intelligent steam oven cavity is equipped with a spice container; controlling the condenser plate to enter the auxiliary heating mode includes the following steps:
[0086] In auxiliary heating mode, the condenser plate is heated to a second target temperature; the second target temperature is used to induce the fragrance placed in the fragrance container to release aroma molecules.
[0087] In this embodiment, when the steam oven operates in auxiliary heating mode to support specific functions, the condenser plate is heated to a preset second target temperature (e.g., 60-80°C). This second target temperature aims to use the heating function of the condenser plate to induce the release of aroma molecules from the spices (e.g., sawdust, tea leaves, herbs, etc.) placed in the spice container, thereby creating a uniform aroma environment within the cavity. This aroma is then mixed with steam through convection within the cavity and evenly applied to the surface of the food to achieve a fragrance or smoking effect.
[0088] It should be noted that the specific value of the second target temperature should be adapted to the type of spice to be heated in order to achieve the best flavor release effect. For example, for herbal spices (such as rosemary and thyme), 60~70℃ can be used to avoid flavor degradation caused by high temperature; for wood chips spices (such as apple wood and walnut wood), 70~85℃ can be used to ensure that they are fully pyrolyzed and produce a rich smoky aroma.
[0089] This embodiment utilizes the auxiliary heating mode of the condenser plate to expand the aroma release function of the smart steam oven. This not only enables the reuse of hardware unit functions and improves system integration, but also allows users to flexibly select different combinations of spices and temperatures according to their cooking needs, achieving a diverse flavor experience.
[0090] In some embodiments, controlling the condenser plate to enter auxiliary heating mode includes the following steps:
[0091] In auxiliary heating mode, the condenser plate is heated to the third target temperature; the third target temperature is used to soften the oil stains inside the intelligent steam oven cavity.
[0092] Specifically, during the standby and low humidity stages of the steam oven, the auxiliary heating mode is activated to control the condenser plate to heat up to the third target temperature (e.g., above 70°C). This third target temperature aims to effectively soften and prevent water droplets and grease from condensing and adhering inside the cavity by raising the temperature of the condenser plate, thereby reducing grease buildup at the source and playing a role in daily cleaning and maintenance.
[0093] For example, in the self-cleaning mode of the steam oven, the condenser plate is controlled to enter a high-temperature working state, raising its surface temperature to 75°C or higher. This softens the oil stains adhering to the condenser plate surface, while food residue is carbonized and loosened under continuous high temperature. This process can be further combined with the steam flushing function, utilizing the impact and dissolving effect of high-temperature steam to completely peel the softened or carbonized dirt off the plate surface and flush it into the water collection tank, effectively preventing long-term accumulation of dirt and helping to extend the service life of the entire machine. In addition, before turning off the steam oven, the auxiliary heating mode can be activated to evaporate the moisture inside the cavity and on the surface of the condenser plate, ensuring that the inside of the equipment remains dry and clean, effectively preventing the generation of odors and the growth of mold.
[0094] This embodiment achieves automated cleaning and maintenance of the intelligent steam oven. It not only solves stubborn stains through a powerful self-cleaning mode, but also improves the hygiene and ease of use of the equipment through intelligent intervention during daily use.
[0095] In some of these embodiments, such as Figure 3 As shown, the control method for the above-mentioned intelligent steam oven also includes the following steps:
[0096] Step S241: When the cooking in the smart steam oven is finished, determine whether the relative humidity value inside the smart steam oven cavity is greater than the preset safety threshold.
[0097] Step S242: If the relative humidity value is greater than the preset safety threshold, control the condenser plate to operate at maximum cooling power.
[0098] Step S243: When the relative humidity value is less than the preset safety threshold, a safety door opening prompt is generated.
[0099] Specifically, when the cooking program of the smart steam oven enters the final stage (e.g., the remaining cooking time is less than 2 minutes), or the system detects a cooking end signal, it determines whether the relative humidity value inside the smart steam oven cavity is greater than a preset safety threshold (e.g., 40~50%). The preset safety threshold can be dynamically adjusted according to different cooking modes (e.g., high-temperature steaming and low-temperature steaming and baking).
[0100] When the current relative humidity value is detected to be higher than the preset safety threshold, the condenser plate is controlled to operate at maximum cooling power, that is, the temperature control unit of the condenser plate is driven at full power, so that the surface temperature of the condenser plate drops rapidly to below the air dew point temperature, thereby forming a strong condensation rate and achieving rapid and safe dehumidification. Once the relative humidity value inside the cavity is lower than the preset safety threshold, a safe door opening prompt (such as an audible prompt or interface icon) is generated to inform the user that the cabinet door can be opened.
[0101] Understandably, if the relative humidity inside the cavity fails to drop to the safe threshold, the door lock unlocking time can be delayed, or the user interface can prompt the user to prioritize the micro-gap dehumidification mode, which slowly releases residual moisture until the door can be safely opened.
[0102] This embodiment utilizes the rapid dehumidification mechanism and safety door opening prompts of the steam oven to effectively prevent users from being burned by high-temperature and high-humidity steam when they finish cooking. At the same time, it can prevent a large amount of water vapor from condensing inside the steam oven, thereby protecting electrical components and internal cavity structure and extending the service life of the entire machine.
[0103] The present embodiment will now be described and illustrated through preferred embodiments.
[0104] Figure 4 This is a flowchart of the control method for the intelligent steam oven according to a preferred embodiment, such as... Figure 4 As shown, the control method of this smart steam oven includes the following steps:
[0105] Step S410: Real-time collection of relative humidity and temperature values inside the intelligent steam oven cavity;
[0106] Step S420: When the relative humidity value is greater than the preset target humidity value and the temperature value is greater than the preset minimum temperature value, control the condenser plate to enter the cooling and dehumidification mode.
[0107] Step S430: In the cooling and dehumidification mode, the surface temperature of the condenser plate is controlled to be lower than the air dew point temperature, so that the water vapor in the cavity condenses into liquid. The condensate flows into the water collection tank along the plate surface and is discharged into the wastewater tank through the guide pipe.
[0108] Step S440: When the relative humidity value is less than the preset target humidity value and the temperature value is greater than the target cavity temperature, control the condenser plate to enter the auxiliary heating mode.
[0109] Step S450: In auxiliary heating mode, control the condenser plate to heat to the target temperature; the target temperature matches the real-time cooking requirements.
[0110] Step S460: When the cooking program of the smart steam oven enters the end stage, determine whether the relative humidity value inside the smart steam oven cavity is greater than the preset safety threshold.
[0111] In step S470, if the relative humidity value is greater than the preset safety threshold, the condenser plate is controlled to operate at maximum cooling power until the relative humidity value is less than the preset safety threshold, and a safe door opening prompt is generated.
[0112] This embodiment collects the relative humidity and temperature values inside the intelligent steam oven cavity in real time. When the relative humidity exceeds the preset target humidity value and the temperature exceeds the preset minimum temperature value, the condenser plate is controlled to enter the cooling and dehumidification mode. In this mode, the surface temperature of the condenser plate is kept below the air dew point temperature, causing water vapor inside the cavity to condense into liquid. The condensate flows along the plate surface into the water collection tank and is then discharged into the wastewater tank through a guide pipe, achieving rapid dehumidification. When the relative humidity is less than the preset target humidity value and the temperature exceeds the target cavity temperature, the condenser plate is controlled to enter the auxiliary heating mode. In this mode, the condenser plate is heated to the target temperature, which matches the real-time cooking requirements. This solves the problem of the dehumidification process affecting the cooking effect and the single function of the dehumidification device. It avoids the dehumidification process affecting the cooking effect and achieves bidirectional regulation of the cavity environment by a single component, improving the utilization rate and control flexibility of the equipment.
[0113] In addition, when the cooking program of the smart steam oven enters the final stage, it checks whether the relative humidity value inside the oven cavity is greater than the preset safety threshold. If the relative humidity value is greater than the preset safety threshold, it controls the condenser plate to operate at maximum cooling power until the relative humidity value is less than the preset safety threshold, generating a safe door opening prompt to effectively prevent steam from rushing out when the oven door is opened.
[0114] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0127] In some embodiments, the control module 30 is also configured to control the condenser plate to heat to a third target temperature in the auxiliary heating mode; the third target temperature is used to soften the oil stains inside the intelligent steam oven cavity.
