[0052] Steam ovens, as multifunctional kitchen appliances that combine steaming and baking, are widely used in home kitchens, hotel kitchens, and professional baking settings. Their core advantage lies in their ability to flexibly achieve various combined cooking modes through the synergistic effect of steam and hot air. Especially when steam is introduced during high-temperature baking, the precise control of humidity within the cavity has a decisive impact on the expansion effect, surface color, internal texture, and retention of nutrients in food.

[0053] In existing technologies, mainstream steam ovens typically use a method of directly spraying room temperature water into a high-temperature cavity to achieve steam-assisted humidification. The moisture is instantly vaporized by the thermal environment inside the cavity, thereby increasing the humidity level inside the cavity.

[0054] However, the temperature settings of steam ovens in baking mode are often as high as 150℃ to 230℃, while the temperature of the directly sprayed warm water is usually no more than 100℃. The introduction of a low-temperature medium causes temperature fluctuations inside the steam oven cavity. This results in uneven heating of food, reduced cooking efficiency, and affects the quality of the final product.

[0055] To address the aforementioned issues, this application proposes a control method, device, and electronic equipment for steam-assisted cooking in a steam oven. By determining the set temperature and capacity of the steam oven, and based on the set temperature and capacity, the steam demand is determined. The steam generator is controlled to produce steam exceeding the demand, and the steam undergoes secondary heating. When the steam temperature reaches the set temperature, the output valve of the steam generator is opened to spray steam into the steam oven, reducing temperature fluctuations during cooking, ensuring even heating of food, and improving cooking quality.

[0056] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0057] Figure 1 A flowchart illustrating a control method for steam-assisted cooking in a steam oven, as provided in this application embodiment. Figure 1 ,like Figure 1 As shown, the control method for steam-assisted cooking in a steam oven provided in this embodiment includes:

[0058] S101. Determine the set temperature and capacity of the steam oven, and determine the steam demand based on the set temperature and capacity.

[0059] The set temperature directly reflects the heat intensity of the current cooking mode. For example:

[0060] In low-temperature steaming mode (e.g., 60℃~90℃), the water vapor saturation in the cavity is high, and a small amount of steam is enough to maintain high humidity;

[0061] Under high-temperature baking mode (e.g., 150℃~220℃), the air dryness and the rate of moisture evaporation are accelerated. To achieve the same relative humidity level, the amount of steam required increases significantly.

[0062] Therefore, the higher the set temperature, the greater the amount of steam required to maintain effective humidification. This positive correlation stems from the increased water-holding capacity of air at high temperatures, necessitating the injection of more water vapor to achieve the target humidity level.

[0063] The capacity determines the volume of the space that needs to be humidified. Smaller capacities require less steam to quickly raise the overall humidity; while larger capacities require more steam to achieve a uniform and effective humidity distribution. The larger the cavity volume, the greater the amount of steam required to achieve the same humidity level.

[0064] One possible approach is to calibrate the amount of steam required to achieve ideal cooking humidity under different combinations of set temperature and capacity through numerous experiments, and store the results as a lookup table. During oven operation, based on the user-input set temperature and the oven's inherent capacity, the steam demand corresponding to the set temperature and capacity is obtained through table lookup and interpolation.

[0065] Preferably, the steam demand recorded in the lookup table usually includes a certain safety margin (such as +10%) to compensate for deviations in actual operating conditions such as water hardness, voltage fluctuations, and insufficient sealing of the steam oven.

[0066] By using the set temperature and cavity capacity as the basis for determining the amount of steam required, the system avoids insufficient or excessive humidification caused by the traditional fixed steam injection mode, thereby reducing unnecessary steam generation and heating energy consumption.

[0067] S102. Control the steam generator to produce steam no less than the required amount of steam, and perform secondary heating treatment on the steam.

[0068] Steam demand is typically expressed in grams (mass). Since most household steam ovens use constant-power electric steam generators, their steam generation rate per unit time is essentially constant. Therefore, steam demand is converted into steam generator operating time.

[0069]

[0070] The control module sends a start command to the steam generator, instructing it to begin heating the water source and continue operation. During the heating process, the water is heated to boiling and converted into steam.

[0071] The steam generated by the steam generator is limited by the boiling point of water (usually ≤100℃), which is far lower than the set temperature of the steam oven in high-temperature mode. If injected directly, the steam will absorb a large amount of sensible heat, causing the cavity temperature to drop sharply. Therefore, the steam must be reheated to raise its temperature to the set temperature.

[0072] It should be noted that the secondary heating is not turned on continuously, but only after confirming that the steam output is sufficient, in order to save energy.

[0073] S103. When the steam temperature reaches the set temperature, control the output valve of the steam generator to open and spray steam into the steam oven.

[0074] When the actual temperature of the steam after secondary heating is confirmed to have reached or exceeded the set temperature of the steam oven, the control module sends an opening command to the output valve at the steam generator outlet. Upon receiving the opening signal, the valve core of the output valve quickly moves under the drive of electromagnetic force, opening the originally closed steam passage. Under the pressure difference between the internal pressure of the steam generator and the cavity, the high-temperature steam flows at high speed along the steam duct into the steam oven cavity and is evenly sprayed into specific areas of the cavity through preset nozzles or steam outlets.

[0075] The injection process continues until all the required steam for this cycle has been released, or the control module determines the end condition based on the preset injection duration, pressure drop threshold, or flow integral and issues a valve closing command to cut off the steam output.

[0076] This embodiment provides a control method for steam-assisted cooking in a steam oven. The method determines the set temperature and capacity of the steam oven, and determines the steam demand based on the set temperature and capacity. It controls the steam generator to generate steam of no less than the required amount and performs secondary heating on the steam. When the steam temperature reaches the set temperature, it controls the output valve of the steam generator to open and spray the steam into the steam oven. This reduces temperature fluctuations during the cooking process, ensures even heating of food, and improves cooking quality.

[0077] Figure 2 A flowchart illustrating a control method for steam-assisted cooking in a steam oven, as provided in this application embodiment. Figure 2 .like Figure 2 As shown, in Figure 1 Based on the embodiments, the control method for steam-assisted cooking in a steam oven is described in detail, including:

[0078] S201. Determine the set temperature and capacity of the steam oven, and determine the steam demand based on the set temperature and capacity.

[0079] Step S201 is similar to step S101 above, and will not be repeated here.

[0080] S202, Control the steam generator to produce steam no less than the required amount.

[0081] Based on the determined steam demand, which is usually expressed in grams or equivalent steam production time, the working state of the steam generator is precisely controlled to ensure that the total amount of steam actually generated is not less than the demand.

[0082] One possible implementation is that the control module outputs a high level to the main heating circuit of the steam generator to start its internal heating wire. At the same time, if it is an external water supply structure, the water inlet solenoid valve is opened simultaneously to inject a certain amount of water into the evaporation chamber to ensure that the evaporation surface is continuously moist.

[0083] Steam generator throughout The system remains under heating, rapidly heating water to its boiling point and vaporizing it to generate saturated steam. To ensure that the actual steam production is greater than or equal to the demand, the calculated output must be strictly followed. It also reserves a safety margin of 5%–10% to compensate for the decrease in steam production efficiency caused by factors such as water hardness, voltage fluctuations, scaling and aging.

[0084] Throughout the steam generation process, the steam generator's output valve remains closed, preventing the generated steam from escaping and causing it to accumulate within the chamber. This not only helps in determining the steam volume through pressure but also creates a sealed retention condition for subsequent secondary heating.

[0085] S203. Obtain the pressure value inside the steam generator.

[0086] The present invention aims to ensure that the temperature of the steam injected into the oven cavity is not lower than the currently set temperature, thereby avoiding temperature disturbances caused by the injection of low-temperature media. However, in high-temperature cooking scenarios, the actual steam temperature cannot be directly measured due to the following issues:

[0087] High-temperature saturated / superheated steam is highly corrosive to sensors;

[0088] Steam has a high flow rate and low heat capacity, resulting in a lag in the response of traditional temperature probes.

[0089] Sensors placed in narrow steam pipes are prone to clogging or failure.

[0090] Therefore, direct temperature measurement cannot be used as the criterion for valve opening. Instead, an indirect but reliable multi-parameter collaborative judgment mechanism is adopted to achieve the control logic of "steam injection when the temperature reaches the target" while ensuring safety and accuracy.

[0091] S204. When the pressure value is greater than the first pressure threshold, it is determined that the steam generator has generated steam that is not less than the amount of steam required.

[0092] During the operation of the steam generator, if its output valve remains closed, the evaporation chamber forms a nearly sealed volumetric space. As the heating wire continuously heats the water source, the liquid water vaporizes into water vapor, and the mass of the gas phase inside the chamber continuously increases.

[0093] In reality, the steam is saturated, but within a fixed cavity volume and a similar temperature range, the pressure inside the cavity increases monotonically with the mass of steam generated; that is, the more steam, the higher the pressure. Therefore, pressure can be used as an effective proxy variable for the amount of steam accumulated.

[0094] Preferably, the first pressure threshold is preset based on the steam demand and is positively correlated with the set temperature and capacity. The first pressure threshold is not a fixed value, but is dynamically set or obtained by looking up a table based on the steam demand required for the current cooking task.

[0095] One possible implementation is that the control module continuously collects the pressure signal inside the cavity through a pressure sensor installed on the steam generator housing. When the pressure value is greater than a first pressure threshold, it determines that the steam generator has produced steam that is not less than the required amount of steam.

[0096] S205. Adjust the heating power of the heating wire according to the set temperature.

[0097] S206. Control the heating wire to perform secondary heating treatment on the steam according to the heating power.

[0098] One possible implementation is that the control module reads the current set temperature value of the steam oven; based on this set temperature, it determines the corresponding heating power level from a pre-stored mapping relationship.

[0099] The mapping relationship is that the higher the set temperature, the greater the corresponding heating power; for example, when the set temperature is 150℃, the corresponding heating power is 300W; when the set temperature is 200℃, the corresponding heating power is 450W; and when the set temperature is 230℃, the corresponding heating power is 550W. This mapping relationship was obtained through experimental calibration and is stored in the controller's memory.

[0100] The control module outputs a control signal matching the heating power to the drive circuit of the heating wire. The drive circuit adjusts the voltage or duty cycle applied to both ends of the heating wire according to the control signal, so that the heating wire heats up at the target power. When the steam flows through the steam channel where the heating wire is located, it comes into contact with the high-temperature surface of the heating wire, absorbs heat, and its temperature rises; the heating process continues until the steam is heated to a level not lower than the set temperature.

[0101] S207. Obtain the pressure value inside the steam generator. If the pressure value is greater than the second pressure threshold, determine that the steam has completed secondary heating and reached the set temperature.

[0102] S208. Control the steam generator's output valve to open, injecting steam into the steam oven.

[0103] One possible implementation involves using a pressure sensor mounted on the steam generator housing to collect the internal steam pressure in real time. The second pressure threshold is a fixed value or a lookup value pre-calibrated based on the set temperature of the steam oven, and the second pressure threshold is greater than the first pressure threshold. When the real-time pressure value is continuously greater than or equal to the second pressure threshold, the control module determines that the steam has accumulated in the sealed cavity for a sufficient time and has been fully heated under the action of the heating wire, and its temperature has reached or exceeded the current set temperature.

[0104] The control module sends an opening command to the solenoid valve at the steam generator outlet; after receiving the opening command, the solenoid valve actuates and opens the steam passage; high-temperature steam is driven by the internal pressure of the steam generator and is quickly injected into the steam oven cavity through the steam pipe and nozzle; the injection process continues until the preset injection time ends or the pressure drops to the closing threshold, at which point the control module sends a closing command to reset and close the output valve.

[0105] S209. After the steam injection is completed, control the heating wire to continue heating for a preset time to heat the residual steam in the steam pipeline.

[0106] When the control module determines that the steam injection process has ended (e.g., the output valve has been closed, or the injection time has reached the set value), it does not immediately cut off the power supply to the heating wire, but instead starts a delay timer to keep the heating wire in operation.

[0107] The preset duration is either a fixed value or a dynamically determined time value based on the current set temperature. Within the preset duration, the heating wire maintains the same heating power as during the injection phase. A small amount of steam remaining in the steam generator outlet section, steam pipe, and upstream cavity of the valve is further heated by the continuous heat from the heating wire, ensuring its temperature does not fall below the current set temperature of the steam oven. Only after the delay timer reaches the preset duration does the control module issue a command to completely shut down the heating wire's drive circuit, stopping the secondary heating operation.

[0108] This embodiment provides a control method for steam-assisted cooking in a steam oven. This method dynamically determines the required steam quantity by combining the set temperature and capacity of the steam oven, and controls the steam generator to produce sufficient steam accordingly. Using the internal pressure of the steam generator as an indirect judgment criterion, when the pressure exceeds a first pressure threshold corresponding to the steam demand, it is confirmed that the steam output meets the requirements, and the heating wire is activated to reheat the steam. The heating power of the heating wire is dynamically adjusted according to the set temperature to ensure that the steam is effectively heated. Further, a second pressure threshold is used to determine if the steam has reached the set temperature. Based on this, the output valve is opened to inject steam at a temperature not lower than the set temperature into the cavity. After the injection is completed, the heating wire continues to work for a preset time to heat the residual steam in the pipeline, preventing low-temperature residual steam from entering the cavity, fundamentally avoiding temperature fluctuations caused by traditional low-temperature steam or room-temperature water injection.
