[0002] In the kitchen appliance market, steam ovens, as appliances that integrate multiple cooking functions such as steaming and baking, are widely favored by consumers because they can meet diverse cooking needs. Steam ovens are typically equipped with a water tank structure, where water supplied by the tank is converted into steam by a steam generator, thereby achieving the steaming and cooking of food.

[0003] However, in actual use of a steam oven, to ensure there is enough water in the tank for cooking, users need to check the water level and manually add water if necessary, resulting in low convenience. Some steam ovens also require manual setting of water supply parameters, which is not only cumbersome but also demands a certain level of cooking knowledge and experience from the user. For users lacking relevant experience, it is difficult to accurately determine the appropriate water volume for different cooking scenarios, further reducing the ease of use of the steam oven.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] This application provides a steam-roasting device. For example... Figure 1 As shown, the steam oven includes a controller 100 and a steam oven 200. The steam oven 200 includes a water inlet assembly and a steam generating assembly, both of which are electrically connected to the controller 100. The water inlet end of the water inlet assembly is connected to a water network pipeline, and the water outlet end of the water inlet assembly is connected to the steam generating assembly.

[0056] The controller 100 is used to acquire cooking instructions; determine the evaporation coefficient, reference compensation amount, and target cooking time that match the cooking instructions; determine the target water supply amount based on the target cooking time, evaporation coefficient, and reference compensation amount; control the water inlet status of the water inlet component of the steam oven 200 based on the target water supply amount; and also controls the steam generating component of the steam oven 200 to generate steam based on the water introduced by the water inlet component for cooking.

[0057] The water inlet assembly and steam generation assembly can be configured according to specific circumstances. In some embodiments, such as... Figure 2 As shown, the water inlet assembly of the steam oven 200 includes a water inlet treatment device 210 and an opening adjustment device 220. The water inlet end of the water inlet treatment device 210 is used to connect to the water network pipeline, and the water outlet end of the water inlet treatment device 210 is connected to the steam generating assembly 240. The opening adjustment device 220 is disposed between the water inlet treatment device 210 and the steam generating assembly 240.

[0058] The opening adjustment device 220 is used to adjust the water inlet status, which includes water inlet start, water inlet stop, different water inlet flow rates, water inlet duration, and other water inlet-related states. As an example, the opening adjustment device 220 includes a solenoid valve electrically connected to the controller 100, and the water inlet status is adjusted by the on / off state and opening status of the solenoid valve.

[0059] The water treatment device 210 may include a filtration and softening device. The inlet of the filtration and softening device is connected to the water network pipeline, and the outlet is connected to the steam generating assembly 240. An opening adjustment device 220 is disposed between the filtration and softening device and the steam generating assembly 240. This allows municipal tap water to flow into the steam generating assembly 240 after being treated by the filtration and softening modules of the filtration and softening device. The filtration and softening module can remove impurities and odors from the water, reduce hardness, and improve water quality. Consequently, the steam generated by the steam generating assembly 240 is odorless and free of impurities, improving cooking quality and helping to extend the service life of the steam generating assembly 240.

[0060] In some embodiments, the water inlet treatment device 210 further includes a pressure stabilizing device disposed between the filter softening device and the steam generating assembly 240. The pressure stabilizing device can monitor and adjust the outlet water pressure to stabilize it within a expected range. This effectively addresses water network pressure, resulting in a more stable water supply to the steam generating assembly 240, reducing steam fluctuations, and improving cooking performance.

[0061] Furthermore, the water inlet assembly also includes a water storage device 230, which is disposed between the opening adjustment device 220 and the steam generating assembly 240. The water storage device 230 can buffer fluctuations in the water supply network and instantaneous flow changes in the opening adjustment device 220, thereby stabilizing the inlet pressure and flow rate of the steam generating assembly 240. For example, the water storage device 230 can be a water storage tank.

[0062] In actual implementation, the steam oven 200 also includes an interactive device electrically connected to the controller 100. The interactive device is used to receive operation commands issued by the user or operation parameters set by the user. The interactive device is also used to send prompts to the user such as the current cooking status or cooking parameters. The interactive device can be one or more of the following: a central control screen, a voice module, a communication module that can communicate with the user's terminal device (such as a mobile phone, tablet computer, wearable device, etc.).

[0063] As an example, the controller 100 obtains cooking instructions from the user via an interactive device and determines the target water supply volume based on these instructions. The target water supply volume refers to the expected amount of water to be introduced into the steam oven 200 from the external water network. The controller 100 also determines the target operating time and target opening degree of the opening adjustment device 220 based on the target water supply volume. For example, the controller 100 controls the opening adjustment device 220 to open at the target opening degree, entering the water intake state. After the opening time of the opening adjustment device 220 reaches the target operating time, the controller controls the opening adjustment device 220 to close, thereby stopping the water intake.

[0064] In some embodiments, the controller 100 obtains user-inputted adjustment parameters through an interactive device; and updates the evaporation coefficient and baseline compensation amount that match the current cooking instruction based on the user-input adjustment parameters, the current cooking instruction corresponding to the user-input adjustment parameters, and the actual water supply of the cooking process corresponding to the current cooking instruction.

[0065] In some embodiments, the water inlet assembly is further provided with a corresponding sensor or sensor group for detecting the actual water supply. The type and location of the sensor can be determined depending on whether a water storage device 230 is provided. In some embodiments, the water inlet assembly includes a flow meter electrically connected to the controller 100. The flow meter is located at the outlet of the opening adjustment device 220, detects the inlet flow rate in real time, and transmits it to the controller 100. The controller 100 calculates the cumulative inlet volume based on the inlet flow rate by integration to determine the actual water supply. In some embodiments, the water inlet assembly also includes a water level sensor electrically connected to the controller 100. The water level sensor is located in the water storage device 230 to monitor the water level data within the water storage device 230. Thus, a more accurate actual water supply can be obtained by combining the water level data detected by the water level sensor. Furthermore, the controller 100 can also adjust the opening of the opening adjustment device 220 according to the water level data.

[0066] In some embodiments, when the water inlet component is stopped by controlling the opening adjustment device 220 to be turned off, the controller 100 will also determine the actual water supply of the water inlet component by calculating the cumulative total water supply based on the water inlet flow rate; determine the water inlet error based on the actual water supply and the target water supply; and update the evaporation coefficient and the reference compensation amount that match the current cooking instruction based on the actual water supply if the water inlet error is greater than the preset error threshold.

[0067] It is understood that in actual implementation, the water inlet assembly also includes a water inlet pipe, and the various devices are connected through the water inlet pipe. The filter softening device is detachable, facilitating user operation when replacement is needed. The water inlet treatment device 210 can be installed in the cabinet of the steam oven 200, for example, at the back of the cabinet. The cabinet includes a cooking cavity for cooking food, which is connected to a steam generating assembly 240, and the steam generated by the steam generating assembly 240 is input into the cooking cavity. The back of the cabinet refers to the portion between the side wall opposite the cooking cavity and the door and the side wall opposite the cabinet and the door. The door can be a left-opening or right-opening door. Exemplarily, the door is a multi-layered insulated glass door with a two-way damping hinge, which can be opened manually by the user or equipped with automatic opening technology, and can be designed according to actual needs by those skilled in the art.

[0068] This water inlet assembly allows for direct connection between cooking water and the domestic water supply network, eliminating the need for a water tank and thus reducing the need for manual water filling, making the steam oven 200 highly convenient to use. Furthermore, the reduced space required by the water tank allows for a larger cooking cavity.

[0069] In some embodiments, an environmental parameter detection sensor electrically connected to the controller 100 is also provided in the cooking cavity for detecting environmental parameters in the cooking cavity and transmitting them to the controller. The controller adjusts the water inlet duration according to the environmental parameters. Exemplarily, the environmental parameters include steam concentration, and the environmental parameter detection sensor is a steam concentration sensor; the selection of the steam concentration sensor is not limited.

[0070] In some embodiments, the steam oven 200 further includes a drainage component, and the controller 100 is also used to acquire the water accumulation parameters of the drainage component of the steam oven; when the water accumulation parameters reach a preset water accumulation threshold, the controller controls the drainage pump in the drainage component to start running.

[0071] For example, such as Figure 3 As shown, the drainage assembly includes a guide channel 14, a drain pipe (not shown), and a drain pump 15. The outlet end of the guide channel 14 is connected to the inlet end of the drain pipe, and the outlet end of the drain pipe is used to discharge wastewater. The drain pump 15 is installed inside the drain pipe and is electrically connected to the controller 100.

[0072] The cross-section of the drainage channel 14 is V-shaped, with the apex of the V serving as the outlet of the drainage channel 14 and connecting to the inlet of the drain pipe. The two sides of the V-shape are symmetrically distributed relative to the apex, and the distance between the two sides and the bottom surface of the cooking cavity is greater than the distance between the apex of the V-shape and the bottom plane of the cooking cavity. The bottom surface of the cooking cavity is typically parallel to the horizontal plane. Therefore, the drainage channel 14 is installed at an angle relative to the bottom surface of the cooking cavity, with the angle ranging from 5° to 8°, or other angles may be used. This inclined design facilitates rapid drainage and reduces the possibility of water accumulation.

[0073] The steam generating assembly 240 includes an evaporating plate 13 electrically connected to the controller 100, and a guide channel 14 is disposed on the side of the evaporating plate 13 away from the bottom surface of the cooking cavity. A condensate recovery device 12 is provided on the top of the steam oven 200. The condensate recovery device 12 is connected to a drain pipe through a water pipe, thereby guiding the recovered water to the drain assembly by gravity.

[0074] The drainage pipes can be made of 12mm outer diameter anti-clogging pipes to ensure drainage capacity. Depending on the specific circumstances, anti-backflow devices can also be installed inside the drainage pipes to prevent sewage backflow.

[0075] The specific location of the drainage pump 15 is set according to the actual situation; for example, it can be set at the connection between the drainage pipe and the guide channel 14. As an example, the drainage pump 15 is a miniature submersible pump, used to quickly drain accumulated water.

[0076] In practical implementation, the drainage assembly also includes a water level monitoring sensor 16 electrically connected to the controller 100 to monitor water level parameters and transmit them to the controller 100. Exemplarily, the water level monitoring sensor 16 can be a capacitive water level sensor, which offers high detection accuracy. In some embodiments, the water level monitoring sensor 16 is installed in the drainage pipe. Specifically, the water level monitoring sensor 16 is installed at the lowest point, i.e., the apex, of the V-shaped guide channel. The water level parameter refers to the height of the water in the V-shaped guide channel, i.e., the distance from the wastewater surface to the bottom of the channel.

[0077] In some embodiments, the controller 100 obtains the water accumulation parameters of the drainage component of the steam oven through a water accumulation level monitoring sensor; when the water accumulation parameters reach a preset water accumulation threshold, the controller controls the drainage pump in the drainage component to start running.

[0078] The steam oven 200 also includes a cleaning component electrically connected to the controller 100. The cleaning component is disposed in the drain pipe, and the specific location needs to be set according to the actual situation. In some embodiments, the controller 100 is also used to obtain the running time of the drain pump 15; when the running time reaches a preset drainage time threshold, the controller controls the cleaning component of the steam oven to enter the cleaning mode.

[0079] The cleaning component can be a high-frequency pulse cleaning device or a reused drain pump 15. When the high-frequency rinsing mode of the high-frequency pulse cleaning device is activated, its frequency pulse can be 10Hz-15Hz.

[0080] In some embodiments, the controller 100 is further configured to acquire the water accumulation parameters of the drainage component of the steam oven through a water accumulation level monitoring sensor, and control the cleaning component of the steam oven to enter the cleaning mode when the water accumulation parameters reach a preset upper limit threshold of water volume.

[0081] In practical applications, the steam oven 200 also includes a heat dissipation component electrically connected to the controller 100. In some embodiments, the controller 100 is further configured to adjust the heat dissipation parameters of the heat dissipation component according to the water accumulation parameters when the water accumulation parameters reach a water accumulation threshold.

[0082] The heat dissipation component can be a centrifugal fan 18, and the heat dissipation parameters can include the fan speed. The steam oven 200 includes a drawer 110 for storage, and the front end of the drawer 110 (the end near the door) is equipped with a honeycomb-shaped air vent grille 19 for easy heat dissipation. The drawer 110 of the steam oven 200 adopts a segmented guide rail structure and has built-in adjustable dividers 111 for categorized storage of baking utensils. Figure 3In the illustrated embodiment, the door 11 opens to the left. A temperature and humidity sensor 17 is located below the airflow channel 14.

[0083] The aforementioned steam-grill device eliminates the traditional independent water tank structure. Its interactive device uses a touch screen display, which is embedded in the left-opening door 11, freeing up the top space of the cooking cavity. The heat dissipation components (integrating a centrifugal fan and honeycomb grid) are located below the cooking cavity. This sunken layout, along with the layered design of the bottom storage drawer 110, constructs a three-dimensional space utilization system of "cooking layer - heat dissipation functional layer - storage layer," significantly improving the device's volumetric efficiency.

[0084] This application also provides a control method for a steam oven, and this embodiment applies the method to... Figure 1 Taking a steam oven as an example, it is understood that this method can also be applied to a server, or to a system that includes both a steam oven and a server, and is implemented through the interaction between the steam oven and the server. Specifically, the control method of this steam oven can be implemented through the controller 100 within the steam oven, or through other external control devices.

[0085] In one embodiment, the method is applied to Figure 1 The following explanation will be based on controller 100. Figure 4 As shown, the control method of this steam oven includes the following steps:

[0086] Step 202: Obtain cooking instructions.

[0087] The cooking instructions can include cooking modes, ingredient types, etc. For example, the cooking instructions could be "steam fish" or "steam and roast meat." The control system has pre-stored cooking parameters corresponding to different cooking modes and ingredient types, which can include target cooking time, target steam output, etc.

[0088] Cooking instructions can also include user-defined cooking parameters, such as cooking time or steam volume that the user manually adjusts.

[0089] Step 204: Determine the evaporation coefficient, baseline compensation amount, and target cooking time that match the cooking instructions.

[0090] The evaporation coefficient reflects the relationship between water evaporation and cooking temperature, food characteristics, etc., under current cooking conditions. The baseline compensation is used to compensate for water loss that may occur during cooking.

[0091] As an example, the controller pre-stores a parameter matrix. This matrix, indexed by cooking commands, integrates and stores parameters such as the evaporation coefficient and baseline compensation amount corresponding to different cooking commands. For instance, in high-temperature steaming mode, moisture evaporates quickly, resulting in a larger evaporation coefficient and a smaller baseline compensation amount. In low-temperature fermentation mode, the evaporation coefficient is smaller, and the baseline compensation amount is larger to better maintain humidity. When the user inputs a cooking command, the controller can quickly obtain the corresponding evaporation coefficient and baseline compensation amount by querying the parameter matrix.

[0092] The target cooking time can be obtained from the pre-stored data based on the cooking instructions, or it can be manually adjusted by the user. The target cooking time affects the amount of water evaporation. Taking the impact of cooking time on water supply when calculating the target water supply can improve the stability of steam.

[0093] Step 206: Determine the target water supply based on the target cooking time, evaporation coefficient, and baseline compensation amount.

[0094] The target water supply volume refers to the amount of water introduced into the water inlet assembly from the external water network pipeline. Since the water inlet assembly is connected to the steam generation assembly, the water introduced into the water inlet assembly can be directly supplied to the steam generation assembly. Therefore, the amount of water supplied by the water inlet assembly to the steam generation assembly is also the target water supply volume.

[0095] It should be noted that when a water storage device is installed in the water inlet assembly, this device is also connected to the drain assembly. After each cooking cycle, the water in the storage device can be drained through the drain assembly. Upon receiving the next cooking command, water is replenished to the storage device, which then provides a stable water supply to the steam generating assembly. This ensures that the water supplied to the steam generating assembly is at the target level and avoids the use of water that has accumulated over a long period, effectively improving the quality of the steam and reducing the potential adverse effects of water quality issues on cooking.

[0096] Step 208: Control the water inlet status of the steam oven's water inlet component according to the target water supply.

[0097] The water inlet component's water inlet status can include water inlet start, water inlet stop, water inlet flow rate, water inlet duration, and other water inlet-related states. Once the controller determines the target water supply, it immediately initiates control of the water inlet component, putting it into water inlet mode. This allows the steam generating component to generate steam based on the water introduced by the water inlet component, thus starting the cooking process.

[0098] The water inlet flow rate of the water inlet component can be a preset default value or dynamically adjusted according to the target water supply. For example, to address potential fluctuations in water inlet flow, the controller can set a larger initial water inlet flow rate based on the target water supply when initiating water intake. This allows for rapid replenishment of the water storage device during the initial cooking phase, ensuring stable operation of the steam generating component and preventing unstable steam generation due to fluctuations in water inlet flow, which could negatively impact cooking results.

[0099] When certain conditions are met, the controller further adjusts the water inlet component to maintain a constant water flow. These conditions can be set based on actual conditions, such as the steam generation component reaching a steady state, or the water level in the storage device reaching a preset threshold. A steady state of steam generation can be defined as a situation where the steam fluctuation within a certain timeframe (e.g., 2 seconds, 5 seconds) is below a preset fluctuation range. At this point, the controller adjusts the water inlet flow rate, reducing it to maintain a constant water flow and stabilize steam generation. The preset threshold can be set based on the target water supply and actual cooking needs. When the water level in the storage device reaches this threshold, it indicates sufficient water has been stored to handle fluctuations in water flow. In this case, the controller reduces the water inlet flow rate to maintain a constant water flow and prevent over-watering.

[0100] Therefore, users only need to input cooking commands, and the controller can control the water inlet status of the water inlet component according to the cooking commands, thereby enabling the steam generation component to operate stably and making it highly convenient to use.

[0101] The control method of the aforementioned steam oven first obtains the cooking command; then determines the target water supply based on the cooking command; and controls the water inlet status of the steam oven's water inlet component based on the target water supply. The water inlet end of the water inlet component is connected to the water network pipe, and the water outlet end of the water inlet component is connected to the steam generating component of the steam oven. The steam generating component is used to generate steam based on the water introduced by the water inlet component for cooking. Since the steam oven's water inlet component is directly connected to the water network pipe, the user no longer needs to check the water level in the water tank beforehand or add water to the tank. Furthermore, it eliminates the need for complex operations such as manually inputting water supply parameters, and especially avoids the risk of parameter misjudgment due to user lack of experience, making the steam oven highly convenient to use.

[0102] There are multiple ways to determine the target water supply based on cooking instructions. In some embodiments, the controller pre-stores the target water supply that matches each cooking instruction. When the user inputs a cooking instruction, the controller directly retrieves the target water supply corresponding to that instruction from the stored data. This method is simple, direct, and can quickly respond to cooking needs.

[0103] In some embodiments, step 206 includes: determining the target water supply based on the product of the target cooking time and the evaporation coefficient, combined with a baseline compensation amount. As an example, the evaporation coefficient is α, the baseline compensation amount is β, the target cooking time is t, and the target water supply amount = α·t + β.

[0104] Therefore, when determining the target water supply, various practical factors in the cooking process are fully considered, such as cooking time, ingredient characteristics, and steam loss. This allows for an accurate target water supply based on different cooking instructions and actual conditions, thus improving problems such as unstable steam generation and poor cooking results caused by inaccurate water volume. Simultaneously, the parameter matrix design makes parameter storage and retrieval more convenient and efficient, improving the controller's response speed and the overall system performance.

[0105] By assigning different evaporation coefficients and baseline compensation amounts to different cooking modes and food types, steam ovens can better adapt to various cooking scenarios. For example, when steaming vegetables with high moisture content and steaming / roasting meats, the evaporation and water loss will differ due to the different characteristics of the ingredients and cooking requirements. This control method can match the evaporation coefficient and baseline compensation amount according to the actual situation, thereby obtaining the appropriate target water supply in various cooking scenarios, thus improving the versatility and applicability of the steam oven.

[0106] In some embodiments, the control method of the steam oven includes the following steps:

[0107] Obtain user-adjusted parameters;

[0108] Based on the user-adjusted parameters, the current cooking command corresponding to the user-adjusted parameters, and the actual water supply of the cooking process corresponding to the current cooking command, update the evaporation coefficient and the baseline compensation amount that match the current cooking command.

[0109] It's understandable that users may adjust cooking parameters before or during cooking based on their needs. For example, users might manually adjust parameters such as cooking time and steam output according to their desired food texture. The controller monitors and acquires these adjustments in real time, recording the adjusted parameters as user-defined parameters. These user-defined parameters reflect the user's personalized requirements for the cooking effect achievable with the current cooking command. The controller records these user-defined parameters for subsequent optimization of the evaporation coefficient and baseline compensation.

[0110] After cooking, the controller calculates the actual water supply based on the water flow rate transmitted by the flow meter in the water inlet assembly by integrating the flow rate. Then, based on the user's adjustment parameters, the current cooking command, and the actual water supply, the controller updates the evaporation coefficient and baseline compensation amount matching the current cooking command. Specifically, this can be achieved using statistical analysis and machine learning algorithms based on historical data (such as recorded user adjustment parameters and actual water supply). By continuously accumulating and analyzing user adjustment data and actual water usage data, the evaporation coefficient and baseline compensation amount matching the current cooking command are iteratively adjusted. This improves the accuracy of the target water supply obtained from the current cooking command, making the actual water supply more consistent with the user's cooking habits, reducing manual intervention, and further enhancing the ease of use of the steam oven.

[0111] In some embodiments, the control method of the steam oven includes the following steps:

[0112] When the water inlet component is in a stopped water inlet state, determine the actual water supply of the water inlet component;

[0113] The water inlet error is determined based on the actual water supply and the target water supply.

[0114] If the water inlet error exceeds the preset error threshold, the evaporation coefficient and baseline compensation amount are updated to match the current cooking command based on the actual water supply.

[0115] It is understandable that the controller will stop the water inlet component from supplying water when the required water inlet time has elapsed. The controller calculates the actual water supply of the water inlet component by integrating and accumulating the water inlet flow rate transmitted by the flow meter installed in the water inlet component.

[0116] Water inlet error refers to the degree of deviation between the actual water supply and the target water supply. A preset error threshold can be set according to actual conditions, for example, ±3%. When the water inlet error exceeds the preset error threshold, it indicates a significant deviation between the current actual water supply and the target water supply, which may affect the cooking effect. In this case, the control system will update the evaporation coefficient and baseline compensation amount to match the current cooking command based on the actual water supply.

[0117] By dynamically updating the evaporation coefficient and baseline compensation based on the water inlet error, the target water supply can be more accurate, ensuring that there is an appropriate amount of water to generate steam during cooking. This helps maintain a stable cooking environment, reduces fluctuations in cooking results caused by insufficient or excessive water, and improves the stability and consistency of cooking results.

[0118] In some embodiments, such as Figure 5 As shown, after step 208, the control method of the steam oven also includes steps 302 and 304.

[0119] Step 302: Obtain the environmental parameters inside the cooking cavity of the steam oven.

[0120] The environmental parameters within the cooking cavity include steam concentration. In practice, after the controller initiates water intake through the water inlet assembly, it also acquires the steam concentration within the cooking cavity via a steam concentration sensor located inside. Steam concentration directly affects the effect of steam on food during cooking. A suitable steam concentration ensures even heating of food, preserves its moisture and nutrients, and also influences its color, taste, and texture.

[0121] Step 304: Adjust the water inlet time according to environmental parameters.

[0122] When the controller receives a cooking command, it will also determine the appropriate target steam concentration range based on factors such as cooking mode and ingredient type.

[0123] When the steam concentration in the cooking cavity exceeds the target steam concentration range, it indicates that the steam supply may be excessive. In this case, the controller can appropriately shorten the water inlet time, reducing the water supply and thus decreasing the steam volume, allowing the steam concentration to gradually return to a suitable range. If the steam concentration is below the target steam concentration range, it indicates insufficient steam supply. The controller will appropriately extend the water inlet time, increasing the water supply and steam volume to improve the steam concentration.

[0124] In this embodiment, dynamically adjusting the water intake time based on environmental parameters helps improve the food cooking quality of the steam oven and reduce energy consumption. When the steam concentration is too high, shortening the water intake time can reduce unnecessary water waste and energy consumption; when the steam concentration is too low, extending the water intake time can ensure sufficient steam supply and avoid energy waste caused by repeated heating or insufficient steam.

[0125] In some embodiments, the control method of the steam oven further includes the following steps:

[0126] Obtain the water accumulation parameters of the drainage component of the steam oven;

[0127] When the water accumulation parameters reach the preset water accumulation threshold, the drainage pump in the drainage assembly is started and operated.

[0128] The preset water accumulation threshold can be set according to specific circumstances.

[0129] During operation, some of the steam in the cooking cavity of a steam oven condenses and forms water, which flows through the drainage channel to the drain pipe. If this water accumulates inside the steam oven for a long time, it can breed bacteria and mold, producing unpleasant odors and potentially contaminating food, thus reducing the safety of using the steam oven.

[0130] Furthermore, when the accumulated water reaches a certain amount, it may overflow onto the evaporator plate or other components. When water overflows onto the evaporator plate, it may cause uneven temperature distribution, affecting the uniform generation of steam. This, in turn, affects the distribution and concentration of steam within the cooking cavity, leading to uneven heating of food and impacting cooking quality. Other components may include circuit boards; if water seeps into the circuit boards, it poses a risk of short circuits and damage to electronic components.

[0131] In this embodiment, by acquiring the water accumulation parameters of the drainage component and starting the drainage pump when the water accumulation reaches a preset threshold, the drainage pump can quickly drain the water, effectively reducing the risk of water overflow and improving the safety of using the steam oven.

[0132] In some embodiments, after the drain pump in the step control drainage assembly is started, the control method for the steam oven further includes the following steps:

[0133] Obtain the updated water accumulation parameters of the drainage components;

[0134] If the updated water accumulation parameters are lower than the lower limit threshold, the drainage pump will be stopped.

[0135] The lower limit threshold for water accumulation can be set according to specific circumstances. After the drainage pump starts and drains water quickly, the controller continuously monitors the water accumulation parameters. When the water accumulation parameters are lower than the lower limit threshold, it is determined that the water has been basically drained. At this point, the drainage pump is stopped, which can prevent the drainage pump from running dry for a long time, reducing energy waste and equipment wear.

[0136] In some embodiments, after the drain pump in the step control drainage assembly is started, the control method for the steam oven further includes the following steps:

[0137] Obtain the running time of the drainage pump;

[0138] When the running time reaches the preset drainage time threshold, the cleaning component of the steam oven is controlled to enter the cleaning mode.

[0139] During the use of a steam oven, food residue, grease, and other grime may remain inside the cooking cavity. If the drain pump runs for an extended period without effectively draining the water, it means that a significant amount of residue may remain in the drain pipe, leading to a buildup of grime.

[0140] In this embodiment, the cleaning mode is activated after the drain pump has run for a preset drainage time threshold. The cleaning component flushes the drain pipes to prevent dirt buildup and blockages, keeping the drainage channels clear. This reduces problems such as poor drainage and water overflow caused by drain pipe blockages, improving the operational reliability of the steam oven. The preset drainage time threshold is set according to actual conditions. By setting a reasonable preset drainage time threshold, unnecessary energy consumption can be reduced. For example, it prevents the drain pump from running idle for extended periods or over-operating, and it avoids activating the cleaning mode unnecessarily.

[0141] Furthermore, if the running time reaches a preset drainage duration threshold, the controller can also issue an alert to alert the user. If necessary, the user can promptly check for blockages in the drain pipe to prevent the problem from worsening.

[0142] In some embodiments, after the drain pump in the step control drainage assembly is started, the control method for the steam oven further includes the following steps:

[0143] When the water accumulation parameter reaches the preset upper limit threshold, the cleaning component of the steam oven is controlled to enter the cleaning mode.

[0144] The preset water volume upper limit threshold can be set according to the actual situation. The preset water volume upper limit threshold can be greater than the preset water accumulation threshold or equal to the preset water accumulation threshold.

[0145] In this embodiment, when the water accumulation parameter reaches the preset upper limit threshold, it indicates that there may be a significant amount of residue remaining in the drain pipe, resulting in dirt buildup. At this point, the cleaning component enters cleaning mode to promptly remove this dirt. This improves the drainage efficiency of the drain pump, reduces problems such as poor drainage and water overflow caused by drain pipe blockage, and enhances the operational reliability of the steam oven.

[0146] In some embodiments, after controlling the start-up of the drainage pump in the drainage assembly, the method further includes:

[0147] When the water accumulation parameter reaches the preset upper limit threshold, the heat dissipation parameter of the heat dissipation component of the steam oven is adjusted according to the water accumulation parameter.

[0148] If excessive water accumulates in a steam oven during operation and is not promptly removed, it may impair normal heat dissipation. For example, water may hinder heat dissipation, causing localized temperature increases on the evaporator plate, circuit boards, and other components. When the water level reaches the preset upper limit threshold, adjusting the heat dissipation parameters of the heat dissipation components, such as increasing the heat dissipation power, can accelerate heat dissipation and improve the operational safety of the steam oven.

[0149] In some embodiments, the heat dissipation component includes a fan, and the heat dissipation parameters include the fan speed and the water accumulation parameters include the water height. Adjusting the heat dissipation parameters of the steam oven's heat dissipation component based on the water accumulation parameters includes determining the fan speed based on the product of the square of the water height and the heat dissipation coefficient. Specifically, the fan speed... Where K represents the heat dissipation coefficient and h represents the water accumulation height. The heat dissipation coefficient K can be a constant or determined based on factors such as the performance of the heat dissipation components and actual heat dissipation requirements. Therefore, the fan speed is dynamically adjusted according to changes in the water accumulation height. When the water accumulation height increases slightly, the fan speed will increase significantly to more promptly and effectively cope with the heat dissipation pressure brought about by the increased water accumulation.

[0150] Since different cooking modes and ingredients may produce different amounts of water, this method can adaptively adjust the heat dissipation parameters according to the actual water accumulation, making the steam oven adaptable to various usage scenarios and more flexible in use.

[0151] The control method of the aforementioned steam oven dynamically adjusts the target water supply based on different cooking modes to improve steam stability. Utilizing a PID (proportional-integral-derivative) algorithm and a cleaning component, it achieves ±3% water supply error control while also implementing anti-clogging drainage, effectively improving issues such as pipe blockage, limescale residue, and poor steam stability.
