Description

Technical Field

[0001] The present invention relates to the technical field of steam cooking equipment, and in particular to a descaling control method and device for a steam cooking device. Background Art

[0002] Existing steam ovens combine the functions of a steamer and an oven. In the steam mode, since steam is generated during operation, scale is likely to form on the inner surface of the steam generator of the steam oven. In the baking mode, contaminants such as food oil stains and sugar stains will fall on the surface of the steam generator during operation, and thus there are oil stains, sugar stains, etc. on the inner surface of the steam generator. Therefore, there is a problem of aging and scaling in the steam generator of the steam oven. To solve this problem, in the prior art, a cleaning agent or a steel wool ball is generally used to remove the dirt of the steam generator. However, using a cleaning agent to remove scale may cause a small amount of the cleaning agent to remain in the steam generator, which may affect people's health. Using a steel wool ball to remove the dirt of the steam generator not only has problems such as incomplete cleaning or difficult-to-thoroughly clean stains, but also damages the coating on the inner liner of the steam oven, thereby reducing the service life of the machine.

[0003] To solve the above problems, it is disclosed in the prior art to use ultrasonic waves to remove the scale of the steam generator in a single working mode of the steam cooking device. However, this method has limitations and may cause stains generated in different working modes or different working durations to be difficult to completely remove, thereby affecting the service life and normal operation of the equipment. Summary of the Invention

[0004] To solve the above technical problems, the present invention discloses a descaling control method for a steam cooking device, which can determine different cleaning strategies based on different working modes and working times of the steam cooking device, so as to be able to completely remove the stains inside the steam generator, ensure the clean and normal operation of the steam cooking equipment, not only improve the user experience, but also extend the service life of the equipment.

[0005] To achieve the above object, the present invention provides a descaling control method for a steam cooking equipment, which is applied to a steam cooking device. The steam cooking device is provided with a steam generator and an ultrasonic device, and the ultrasonic device is used to provide an ultrasonic sound field to the steam generator. The method includes:

[0006] Obtain the current working state information of the steam cooking device, where the current working state information is used to indicate the working state corresponding to the most recent operation of the steam cooking device;

[0007] Based on the preset correspondence between the working state and the cleaning strategy, determine the target cleaning strategy corresponding to the current working state information;

[0008] When the water volume in the steam generator meets a preset condition, control the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, so as to perform ultrasonic oscillation treatment on the steam generator of the steam baking device.

[0009] In a possible implementation manner, the current working information includes the last running duration, working mode, and the corresponding cumulative usage times of the working mode of the steam baking device. Based on the corresponding relationship between the preset working state and the cleaning strategy, determining the target cleaning strategy corresponding to the current working state information includes:

[0010] If the working mode is the steaming mode and the cumulative usage times are greater than a first preset number of times, and / or the last running duration is greater than or equal to a first preset duration, determine that the target cleaning strategy of the steam baking device is a forced cleaning strategy, and the forced cleaning strategy is used to automatically trigger a cleaning event of the steam baking device.

[0011] In a possible implementation manner, the current working information includes the last running duration, working mode, and the corresponding cumulative usage times of the working mode of the steam baking device. Based on the corresponding relationship between the preset working state and the cleaning strategy, determining the target cleaning strategy corresponding to the current working state information includes:

[0012] When the last running duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset number of times, determine the target cleaning strategy based on the last working mode, the running duration, and the preset corresponding relationship. Each working mode includes multiple sub - modes, and the preset corresponding relationship includes the corresponding relationship between multiple sub - modes, multiple running durations, and cleaning strategies.

[0013] In a possible implementation manner, the descaling parameters corresponding to the target cleaning strategy include the ultrasonic working frequency of the ultrasonic device. When the last running duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset number of times, the ultrasonic working frequency of the determined target cleaning strategy is higher than the ultrasonic working frequency corresponding to the forced cleaning strategy;

[0014] The working mode includes a steaming mode and a baking mode, and the ultrasonic working frequency of the target cleaning strategy corresponding to the steaming mode is lower than the ultrasonic working frequency of the target cleaning strategy corresponding to the baking mode.

[0019] The heating temperature of the forced cleaning strategy determined when the last operation duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steam mode are less than the first preset times is less than the heating temperature of the forced cleaning strategy determined when the last operation duration of the steam baking device is greater than the first preset duration.

[0020] In a possible implementation, the steam baking device is provided with a heating device for heating the steam generator, and the descaling parameters corresponding to the cleaning strategy include the heating temperature. The method satisfies at least one of the following characteristics:

[0023] In a possible implementation, before controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, it includes:

[0024] Obtain the cavity placement information and door state information of the steam baking device;

[0025] If the cavity placement information indicates that the cavity of the steam baking device is empty and the door state information indicates that the door of the steam baking device is closed, execute the step of controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy.

[0026] In a possible implementation, after controlling the operation of the ultrasonic device based on the descaling parameters indicated by the target cleaning strategy, the method further includes:

[0027] In response to the completion of the cleaning operation corresponding to the target cleaning strategy, obtain a cavity image of the inner cavity of the steaming and baking device and a pre-stored cavity image, where the pre-stored cavity image is collected when the inner cavity of the steaming and baking device is in a clean state;

[0028] Determine the current cleanliness of the inner cavity of the steaming and baking device based on the comparison result between the current image and the pre-stored cavity image;

[0029] If the current cleanliness is lower than the preset cleanliness, control the ultrasonic device to continuously operate for a preset duration based on the descaling parameters indicated by the target cleaning strategy until it is detected that the cleanliness of the inner cavity of the steaming and baking device is greater than or equal to the preset cleanliness, and then control the ultrasonic device to stop operating.

[0030] The present invention also provides a descaling control device applied to a steaming and baking device. The steaming and baking device is provided with a steam generator and an ultrasonic device, and the ultrasonic device is used to provide an ultrasonic sound field to the steam generator.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned accompanying drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or server comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0049] Please refer to Figure 1 , which shows a schematic flowchart of a descaling control method for a steaming and baking device provided by the embodiments of the present invention. This specification provides the method operation steps as described in the embodiments or flowcharts, but based on routine or non-creative labor, it may include more or fewer operation steps. The step sequence listed in the embodiments is only one of the execution sequences of numerous steps and does not represent the only execution sequence. In actual execution of the system or server product, it can be executed in the method sequence shown in the embodiments or the accompanying drawings. Specifically, as Figure 1As shown, the descaling control method of the steaming and baking device is applied to the steaming and baking device. The steaming and baking device is provided with a steam generator and an ultrasonic device. The ultrasonic device is used to provide an ultrasonic sound field to the steam generator. The method includes:

[0050] S1: Obtain the current working state information of the steaming and baking device. The current working state information is used to indicate the working state corresponding to the most recent operation of the steaming and baking device.

[0051] In some embodiments, the steaming and baking device may be a steamer, an oven, or a steaming and baking integrated machine.

[0052] In some embodiments, the current working state information includes the most recent operation duration, working mode, and the cumulative usage times corresponding to the working mode of the steaming and baking device.

[0053] Specifically, the working mode is a steaming mode or a baking mode.

[0054] In some embodiments, the current working state information further includes the food type of the steaming and baking device.

[0055] S2: Based on the preset correspondence between the working state and the cleaning strategy, determine the target cleaning strategy corresponding to the current working state information.

[0056] In some embodiments, based on the preset correspondence between the working state and the cleaning strategy, determining the target cleaning strategy corresponding to the current working state information includes S10 - S11:

[0057] S10: If the working mode is the steaming mode and the cumulative usage times are greater than the first preset times, and / or the most recent operation duration is greater than or equal to the first preset duration, determine that the target cleaning strategy of the steaming and baking device is a forced cleaning strategy. The forced cleaning strategy is used to automatically trigger the cleaning event of the steaming and baking device. By defining the forced cleaning strategy, after the steaming and baking device reaches a certain number of usage times and a relatively long operation duration, the steaming and baking device can automatically perform cleaning, greatly saving the user's time and energy, and also preventing the accumulation of water scale and oil stains, and extending the service life of the steaming and baking device.

[0058] Specifically, the first preset times can be set to be greater than or equal to 21 times; it can be understood that the first preset times can be any point value within the above range, and no enumeration is made here.

[0059] Specifically, the first preset duration can be set to be greater than 240 min; it can be understood that the first preset duration can be any point value within the above range, and no enumeration is made here.

[0060] In some embodiments, as Figure 2 shown, the specific process of determining the target cleaning strategy corresponding to the current working state information includes:

[0061] S12: Obtain the working status information of the steam cooking device. The working status information includes the most recent running duration, working mode, cumulative usage times corresponding to the working mode, and the food type of the steam cooking device;

[0062] S13: Determine whether the most recent running duration of the steam cooking device is greater than a first preset duration. If so, execute S17; if not, execute S14;

[0063] S14: Determine whether the most recent working mode of the steam cooking device is the steaming mode. If so, execute S15; if not, execute S16;

[0064] S15: Determine whether the cumulative usage times of the steam cooking device is greater than a first preset number of times. If so, execute S17;

[0065] S16: Determine whether the most recent working mode of the steam cooking device is the baking mode. If so, execute S18;

[0066] S17: The steam cooking device enters the forced cleaning strategy;

[0067] S18: Confirm that the target cleaning strategy corresponding to the current working status information is the forced cleaning strategy.

[0068] In some embodiments, when the most recent running duration of the steam cooking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode is less than the first preset number of times, before determining the target cleaning strategy based on the most recent working mode, running duration, and preset corresponding relationship, the method further includes:

[0069] S224: When the most recent running duration of the steam cooking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode is less than the first preset number of times, display a cleaning prompt message, where the cleaning prompt message is used to indicate the executable cleaning strategy;

[0070] S225: In response to a cleaning request submitted for the cleaning prompt message, execute the step of determining the target cleaning strategy based on the most recent working mode, running duration, and preset corresponding relationship. By displaying the cleaning prompt message, the user can be reminded that the steam cooking device needs to be cleaned, avoiding factors such as the user forgetting or neglecting, resulting in too much scale in the steam generator of the steam cooking device and being difficult to remove, and at the same time avoiding the normal operation of the steam cooking device being affected due to serious scale.

[0071] Specifically, when the most recent running duration of the steam cooking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode is less than the first preset number of times, before determining the target cleaning strategy based on the most recent working mode, running duration, and preset corresponding relationship, the method further includes:

[0072] When the most recent operation duration of the steaming and baking device is less than the first preset duration, the cumulative usage times corresponding to the steaming mode are less than the first preset times, and the cumulative usage times corresponding to the steaming mode are greater than the second preset usage times, display a cleaning prompt message, where the cleaning prompt message is used to indicate that a cleaning strategy can be executed;

[0073] In response to a cleaning request submitted for the cleaning prompt message, execute the step of determining a target cleaning strategy based on the most recent working mode, operation duration, and preset correspondence.

[0074] In some embodiments, the second preset times can be 11 times.

[0075] In some embodiments, when the most recent operation duration of the steaming and baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the second preset usage times, before determining the target cleaning strategy based on the most recent working mode, operation duration, and preset correspondence, the method further includes:

[0076] When the most recent operation duration of the steaming and baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the second preset times, display a cleaning prompt message, where the cleaning prompt message is used to indicate that a cleaning strategy can be executed;

[0077] In response to a cleaning request submitted for the cleaning prompt message, execute the step of determining a target cleaning strategy based on the most recent working mode, operation duration, and preset correspondence.

[0078] Specifically, the cleaning prompt message includes the cumulative usage times corresponding to the steaming and baking device in the steaming mode.

[0079] By displaying the cleaning prompt message to the user, the user is enabled to select whether to execute the cleaning strategy. If the user selects to execute, the steaming and baking device executes the cleaning strategy; if the user selects not to execute, the steaming and baking device does not execute the cleaning strategy. This user-friendly setting improves the user experience and can avoid the long-term accumulation of dirt, thereby increasing the service life of the steaming and baking device.

[0080] In some embodiments, before determining the target cleaning strategy corresponding to the current working state information, the method further includes: clearing the cumulative usage times corresponding to the steaming and baking device in the steaming mode, and executing the step of controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy.

[0081] In some embodiments, as Figure 2 shown, the specific process of displaying the cleaning prompt message includes:

[0082] S15: Whether the cumulative usage times of the steaming and baking device are greater than the first preset times. If not, execute S151;

[0083] S151: Whether the cumulative usage times of the steam cooking device are less than the first preset times and greater than the second preset times. If so, execute step S152; if not, execute step S153;

[0084] S152: Display a cleaning prompt message.

[0085] S153: Display a cleaning prompt message.

[0086] In some embodiments, based on the corresponding relationship between the preset working states and the cleaning strategies, determining the target cleaning strategy corresponding to the current working state information includes:

[0087] S11: When the most recent operation duration of the steam cooking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times, based on the most recent working mode, operation duration, and the preset corresponding relationship, determining the target cleaning strategy. Each working mode includes multiple sub - modes, and the preset corresponding relationship includes the corresponding relationship between multiple sub - modes, multiple operation durations, and cleaning strategies. By determining the target cleaning strategy based on the most recent working mode, operation duration, and the preset corresponding relationship, and at the same time defining that each working mode includes multiple sub - modes, and the preset corresponding relationship includes the corresponding relationship between multiple sub - modes, multiple operation durations, and cleaning strategies, different cleaning strategies are set according to different sub - modes and different operation durations, so as to be able to completely remove the dirt generated in specific situations, avoid the phenomenon that the stains generated under different working modes or different working durations are difficult to be completely removed, and enable the device to work properly.

[0088] In some embodiments, under the condition of the same operation duration, the working temperature of the sub - mode is positively correlated with the cleaning duration.

[0089] In some embodiments, in the same sub - mode corresponding to the steaming mode, the operation duration is positively correlated with the cleaning duration. Since the higher the working temperature of the sub - mode, the more the vaporization of the water entering the inner cavity of the steam cooking device will be intensified, and thus more water will be consumed. Therefore, the higher the working temperature of the sub - mode, the more scale will be generated. Therefore, it is defined that the working temperature of the sub - mode is positively correlated with the cleaning duration. And since the amount of scale generated under different operation durations is different, in order to ensure that the scale can be removed completely, it is necessary to define that the operation duration is positively correlated with the cleaning duration.

[0090] In some embodiments, when the most recent working mode is the steaming mode and the working temperature of the sub - mode of the steaming mode is less than the first preset working temperature, based on the most recent operation duration of the steam cooking device, determining the ultrasonic time of the target cleaning strategy corresponding to the situation where the most recent operation duration of the steam cooking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times.

[0091] In some embodiments, the first preset operating temperature may be 100°C.

[0092] In some embodiments, when the most recent operating mode is the steaming mode and the operating temperature of the sub-mode of the steaming mode is less than the first preset operating temperature, based on the most recent operating duration of the steam baking device, when the most recent operating duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times, the ultrasonic time of the target cleaning strategy corresponding thereto includes S110 - S113:

[0093] S110: If the most recent operating duration of the steam baking device is less than the first preset operating duration, the ultrasonic time of the target cleaning strategy corresponding thereto when the most recent operating duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times is the first ultrasonic time;

[0094] S111: If the most recent operating duration of the steam baking device is greater than the first preset operating duration and less than the second preset operating duration, the ultrasonic time of the target cleaning strategy corresponding thereto when the most recent operating duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times is the second ultrasonic time;

[0095] S112: If the most recent operating duration of the steam baking device is greater than the second preset operating duration and less than the third preset operating duration, the ultrasonic time of the target cleaning strategy corresponding thereto when the most recent operating duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times is the third ultrasonic time;

[0096] S113: If the most recent operating duration of the steam baking device is greater than the third preset operating duration, the ultrasonic time of the target cleaning strategy corresponding thereto when the most recent operating duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times is the fourth ultrasonic time.

[0097] In some embodiments, as Figure 3 shown, the specific process of determining the ultrasonic time of the target cleaning strategy corresponding thereto when the most recent operating duration of the steam baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times includes:

[0098] S19: The operating mode of the steam baking device is the steaming mode;

[0099] S20: Whether the most recent operating temperature of the steam baking device is less than the first preset operating temperature. If so, execute S21;

[0100] S21: Whether the most recent operation duration of the steam cooking and baking device is less than the first preset working duration. If so, execute S22;

[0101] S22: Confirm that the ultrasonic time of the target cleaning strategy is the first ultrasonic time;

[0107] S28: Confirm that the ultrasonic time of the target cleaning strategy is the fourth ultrasonic time.

[0108] In some embodiments, when the most recent working mode is the steam mode and the working temperature of the sub - mode of the steam mode is greater than the first preset working temperature, the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam cooking and baking device is less than the first preset duration and the cumulative usage times corresponding to the steam mode is less than the first preset times is determined based on the most recent operation duration of the steam cooking and baking device.

[0109] Specifically, when the most recent working mode is the steam mode and the working temperature of the sub - mode of the steam mode is greater than the first preset working temperature, determining the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam cooking and baking device is less than the first preset duration and the cumulative usage times corresponding to the steam mode is less than the first preset times includes S114 - S117:

[0110] S114: If the most recent operation duration of the steam cooking and baking device is less than the first preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam cooking and baking device is less than the first preset duration and the cumulative usage times corresponding to the steam mode is less than the first preset times is the fifth ultrasonic time;

[0111] S115: If the last running duration of the steaming and baking device is greater than the first preset working duration and less than the second preset working duration, and the last running duration of the steaming and baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are less than the first preset times, the ultrasonic time of the target cleaning strategy corresponding thereto is the sixth ultrasonic time;

[0118] S32: Confirm that the ultrasonic time of the target cleaning strategy is the fifth ultrasonic time;

[0119] S33: Whether the last running duration of the steaming and baking device is greater than the first preset working duration and less than the second preset working duration. If so, execute S34; if not, execute S35;

[0120] S34: Confirm that the ultrasonic time of the target cleaning strategy is the sixth ultrasonic time;

[0125] Exemplarily, the first preset working duration can be set to be greater than or equal to 60 min, the range of the second preset working duration is 61 - 120 min, and the range of the third preset working duration is 121 min - 180 min.

[0126] Exemplarily, the first ultrasonic time is 3 min, the second ultrasonic time is 7 min, the third ultrasonic time is 10 min, the fourth ultrasonic time is 15 min, the fifth ultrasonic time is 2 min, the sixth ultrasonic time is 5 min, the seventh ultrasonic time is 8 min, and the eighth ultrasonic time is 10 min.

[0127] In the steaming mode, different ultrasonic times of the cleaning strategy are determined according to different operation durations of the steaming and baking device, so as to ensure that the scale in the steaming and baking device can be removed completely, and avoid the phenomenon that the scale cannot be removed completely due to too long operation duration and too short ultrasonic time.

[0128] In some embodiments, based on the most recent working mode, operation duration and preset corresponding relationship, the target cleaning strategy is determined. Each working mode includes multiple sub - modes, and the preset corresponding relationship includes the corresponding relationship among multiple sub - modes, multiple operation durations and cleaning strategies, including:

[0132] Specifically, when the sub - mode of the baking mode is the manual mode, the ultrasonic time of the target cleaning strategy corresponding to the case where the last running duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times is determined, including S2230 - S2231:

[0134] S2231: If the last running duration of the steam - baking device is less than the second preset working duration and greater than the first preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the case where the last running duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times is the tenth ultrasonic time;

[0135] If the last running duration of the steam - baking device is greater than the second preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the case where the last running duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times is the eleventh ultrasonic time.

[0136] In some embodiments, as Figure 5 shown, the specific process of determining the ultrasonic time of the target cleaning strategy corresponding to the case where the last running duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times includes:

[0144] S46: Confirm that the ultrasonic time of the target cleaning strategy is the eleventh ultrasonic time;

[0145] In some embodiments, based on the most recent working mode, operation duration, and preset correspondence, determine the target cleaning strategy. Each working mode includes multiple sub - modes, and the preset correspondence includes the correspondence between multiple sub - modes, multiple operation durations, and cleaning strategies, including S2232 - S2233:

[0146] S2232: When the most recent working mode is the baking mode, determine the target cleaning strategy based on the correspondence between multiple sub - modes of the baking mode, multiple operation durations, food types, and cleaning strategies. Each baking mode includes multiple sub - modes, and the preset correspondence includes the correspondence between multiple sub - modes, multiple operation durations, food types, and cleaning strategies.

[0147] In some embodiments, when the most recent working mode is the baking mode, determine the target cleaning strategy based on the correspondence between multiple sub - modes of the baking mode, multiple operation durations, food types, and cleaning strategies, including:

[0148] S2233: When the sub - mode of the baking mode is the intelligent dish mode and the food type is meat, determine the ultrasonic time of the target cleaning strategy corresponding to the situation where the most recent operation duration of the steaming and baking device is less than the first preset duration and the cumulative usage times of the steaming mode are less than the first preset times based on the most recent operation duration of the steaming and baking device.

[0150] S2234: If the most recent operation duration of the steaming and baking device is less than the first preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the situation where the most recent operation duration of the steaming and baking device is less than the first preset duration and the cumulative usage times of the steaming mode are less than the first preset times is the twelfth ultrasonic time;

[0151] S2235: If the most recent operation duration of the steam cooking and baking device is greater than the first preset working duration and less than the second preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam cooking and baking device is less than the first preset duration and the cumulative usage times of the steaming mode are less than the first preset times is the thirteenth ultrasonic time.

[0152] In some embodiments, such as Figure 6 as shown in, the specific process of determining the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam cooking and baking device is less than the first preset duration and the cumulative usage times of the steaming mode are less than the first preset times includes:

[0153] S47: The working mode of the steam cooking and baking device is the baking mode;

[0154] S48: Whether the sub - mode of the baking mode of the steam cooking and baking device is the intelligent dish mode. If so, execute S48;

[0157] S51: Confirm that the ultrasonic time of the target cleaning strategy is the twelfth ultrasonic time;

[0158] S52: Whether the most recent operation duration of the steam cooking and baking device is greater than the first preset working duration and less than the second preset working duration. If so, execute S53;

[0159] S53: Confirm that the ultrasonic time of the target cleaning strategy is the thirteenth ultrasonic time;

[0160] In some embodiments, when the most recent working mode is the baking mode, based on the corresponding relationship between multiple sub - modes, multiple operation durations, food types and cleaning strategies of the baking mode, the target cleaning strategy is determined, including S2236 - S2237:

[0161] S2236: When the sub - mode of the baking mode is the intelligent dish mode and the food type is pasta, fruits and vegetables, based on the most recent operation duration of the steam cooking and baking device, determine the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam cooking and baking device is less than the first preset duration and the cumulative usage times of the steaming mode are less than the first preset times.

[0162] Specifically, when the sub - mode of the baking mode is the intelligent dish mode and the food type is pastries, fruits and vegetables, determining the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times includes:

[0163] S2237: If the most recent operation duration of the steam - baking device is less than the first preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times is the fourteenth ultrasonic time;

[0164] S2238: If the most recent operation duration of the steam - baking device is greater than the first preset working duration and less than the second preset working duration, the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times is the fifteenth ultrasonic time.

[0165] In some embodiments, as Figure 7 shown, the specific process of determining the ultrasonic time of the target cleaning strategy corresponding to the case where the most recent operation duration of the steam - baking device is less than the first preset duration and the cumulative usage times of the steaming mode is less than the first preset number of times includes:

[0166] S54: The working mode of the steam - baking device is the baking mode;

[0167] S55: Whether the sub - mode of the baking mode of the steam - baking device is the intelligent dish mode. If so, execute S56;

[0168] S56: Whether the food type is pastries, fruits and vegetables. If so, execute S57;

[0169] S57: Whether the most recent operation duration of the steam - baking device is less than the first preset working duration. If so, execute S58; if not, execute S59;

[0170] S58: Confirm that the ultrasonic time of the target cleaning strategy is the fourteenth ultrasonic time;

[0171] S59: Whether the most recent operation duration of the steam - baking device is greater than the first preset working duration and less than the second preset working duration. If so, execute S60;

[0172] S60: Confirm that the ultrasonic time of the target cleaning strategy is the fifteenth ultrasonic time;

[0173] Exemplarily, the first preset working duration can be set to be greater than or equal to 60 min, and the range of the second preset working duration is 61 - 120 min.

[0174] Exemplarily, the ninth ultrasonic time is 2 min, the tenth ultrasonic time is 3 min, the eleventh ultrasonic time is 5 min, the twelfth ultrasonic time is 2 min, the thirteenth ultrasonic time is 4 min, the fourteenth ultrasonic time is 2 min, and the fifteenth ultrasonic time is 5 min.

[0175] Since the stains in the baking mode are relatively stubborn and difficult to remove, such as the sugar stains dropped by baked sweet potatoes, the oil stains dropped by roasted meats, and the residues after food is burnt, therefore, in order to completely remove the stains in the baking mode, the present application defines that the sub - modes in the baking mode include a manual mode and an intelligent dish mode. In different sub - modes, the ultrasonic time of the cleaning strategy is determined according to the operating duration of the steaming and baking device, so as to be able to remove the relatively stubborn stains in the baking mode. On this basis, the present application determines the ultrasonic time of the cleaning strategy according to different food types in the intelligent dish mode, so as to be able to remove specific types of stains according to different food types, making the stain removal cleaner and more efficient.

[0176] In some embodiments, the heating temperature of the cleaning strategy corresponding to the steaming mode is less than the heating temperature of the cleaning strategy corresponding to the baking mode.

[0177] Specifically, the range of the heating temperature of the cleaning strategy corresponding to the steaming mode is 30 - 50 °C. Preferably, the range of the heating temperature of the cleaning strategy corresponding to the steaming mode is 35 - 45 °C. Further preferably, the heating temperature of the cleaning strategy corresponding to the steaming mode is 40 °C. Since the stains generated by the device in the steaming mode are water scales, and compared with pollutants such as oil stains, water scales are easier to remove. Therefore, the present application defines the heating temperature in the steaming mode, which can not only ensure the complete removal of water scales, but also make the device more energy - efficient.

[0178] In some embodiments, the heating temperature of the forced cleaning strategy determined when the most recent operating duration of the steaming and baking device is less than the first preset duration and the cumulative usage times corresponding to the steaming mode are greater than the first preset times is less than the heating temperature of the forced cleaning strategy determined when the most recent operating duration of the steaming and baking device is greater than the first preset duration. Since the latter working mode may be the baking mode, the stains generated may be oil stains. In order to ensure that the oil stains can be completely removed, the heating temperature of the latter is defined to be larger, while the former working mode is the baking mode, and the stains generated are water scales, which can be completely removed without too high a heating temperature.

[0179] Specifically, when the duration of the most recent operation of the steam cooking device is greater than the first preset duration, the range of the heating temperature corresponding to the forced cleaning strategy is 70 - 90°C. Preferably, when the duration of the most recent operation of the steam cooking device is greater than the first preset duration, the range of the heating temperature corresponding to the forced cleaning strategy is 75 - 85°C. Further preferably, when the duration of the most recent operation of the steam cooking device is greater than the first preset duration, the heating temperature corresponding to the forced cleaning strategy is 80°C. Since the operation time of the steam cooking device is relatively long and the amount of stains generated is large, the range of this temperature is limited, so as to ensure that the stains generated during a relatively long single operation time of the device can be completely removed.

[0180] In some embodiments, the descaling parameter corresponding to the target cleaning strategy includes the ultrasonic working frequency of the ultrasonic device. When the duration of the most recent operation of the steam cooking device is less than the first preset duration and the cumulative number of uses corresponding to the steaming mode is less than the first preset number, the ultrasonic working frequency of the target cleaning strategy determined is higher than the ultrasonic working frequency corresponding to the forced cleaning strategy;

[0181] The working modes include the steaming mode and the baking mode. The ultrasonic working frequency of the target cleaning strategy corresponding to the steaming mode is lower than that corresponding to the baking mode. Further, it is defined that the ultrasonic working frequency in the baking mode is greater than that in the steaming mode. The reason for the relatively high ultrasonic working frequency in the baking mode is mainly that under the same sound pressure, the number of cavitation bubbles generated by the ultrasonic device is large, but the cavitation intensity generated during fragmentation is low, the noise is small, and the penetration ability is strong. It is more suitable for removing dirt with relatively weak surface adhesion generated in the baking mode, and can also timely remove stains with relatively weak adhesion generated in the steaming mode, avoiding damage to the inner tank of the steam cooking device caused by continuous high frequency and reducing the service life of the steam cooking device. In addition, the ultrasonic working frequency used in the forced cleaning mode is relatively low, which can obtain a relatively small number of cavitation bubbles, generate noise, but has a large cavitation intensity, and can be used to clean the water scale and stains generated in the case of long-term use of the steaming mode without timely cleaning and long single operation time.

[0182] In some embodiments, when the duration of the most recent operation of the steam cooking device is less than the first preset duration and the cumulative number of uses corresponding to the steaming mode is less than the first preset number, the ultrasonic working frequency of the target cleaning strategy determined can be 30HZ - 39HZ; it can be understood that the ultrasonic working frequency can be any point value within the above range, and no enumeration is made here. Preferably, the ultrasonic working frequency is generally 30HZ.

[0183] In some embodiments, the ultrasonic frequency of the forced cleaning strategy can be 20 - 29 HZ. It can be understood that the ultrasonic working frequency can be any point value within the above range, and no enumeration is made here. Preferably, the ultrasonic frequency of the forced cleaning strategy can be 20 HZ.

[0184] In some embodiments, the ultrasonic working frequency of the target cleaning strategy corresponding to the baking mode can be 40 - 50 HZ. It can be understood that the ultrasonic working frequency can be any point value within the above range, and no enumeration is made here. Preferably, the ultrasonic working frequency of the target cleaning strategy corresponding to the baking mode can be 40 HZ.

[0185] In some embodiments, before controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, the method further includes:

[0186] Obtaining the cavity placement information and door state information of the steam - baking device;

[0187] If the cavity placement information indicates that the cavity of the steam - baking device is empty and the door state information indicates that the door of the steam - baking device is closed, perform the step of controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy. Before performing the cleaning operation, it is necessary to determine whether the door of the steam - baking device is closed, in order to make the entire cleaning process occur in a closed environment, avoid water vapor leakage during the cleaning process, and ensure the effectiveness and safety of the cleaning process.

[0188] In some embodiments, before controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, the method further includes:

[0189] If the cavity placement information indicates that the cavity of the steam - baking device is not empty or the door state information indicates that the door of the steam - baking device is not closed, display the cavity placement information or the door state information, and the cavity placement information or the door state information is used to indicate the executable cleaning strategy.

[0190] In some embodiments, as Figure 8 shown, after determining the target cleaning strategy, the method further includes obtaining the cavity placement information and door state information of the steam - baking device, and the specific process of obtaining the cavity placement information and door state information of the steam - baking device includes:

[0191] S18: Determine the target cleaning strategy;

[0192] S181: Determine whether the door of the steam - baking device is closed. If it is closed, execute S182; if it is not closed, execute S183;

[0193] S182: Determine whether the cavity of the steam - baking device is empty. If it is, execute S3; if not, execute S184;

[0194] S183: Display the door state information;

[0195] S184: Display the information of the items placed in the cavity;

[0196] S3: When the water volume in the steam generator meets the preset conditions, control the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, so as to perform ultrasonic oscillation treatment on the steam generator of the steaming and baking device. Using ultrasonic waves to remove scale can not only effectively remove various types of stains, but also be more environmentally friendly and safe. It solves the problems of firm, caked, adhered stains and easy attachment to the bottom of the machine, improves the heat conduction efficiency of the steam generator or the heating tube, avoids the hazards brought by using cleaners during the cleaning process, and extends the service life of the equipment.

[0197] Specifically, when the water volume in the steam generator meets the preset conditions, control the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, so as to perform ultrasonic oscillation treatment on the steam generator of the steaming and baking device, including:

[0198] Respond to the cleaning request corresponding to the target cleaning strategy, and obtain the current water volume in the steam generator;

[0199] If the current water volume in the steam generator is lower than the preset water volume, add water to the steam generator until the current water volume in the steam generator is greater than or equal to the preset water volume, and control the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, so as to perform ultrasonic oscillation treatment on the steam generator of the steaming and baking device. Adding enough water in the steam generator can greatly improve the cavitation effect of ultrasonic waves, ensuring the descaling effect. At the same time, if the water volume is small, the energy of ultrasonic waves cannot be fully transmitted and act on the steam generator, which will greatly affect the descaling efficiency.

[0200] In some embodiments, the descaling parameters include the ultrasonic working frequency of the ultrasonic device, the heating temperature of the heating device, and the ultrasonic time for operating the ultrasonic device.

[0201] In some embodiments, after controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy, the method further includes:

[0202] S4: Respond to the completion of the cleaning operation corresponding to the target cleaning strategy, obtain the cavity image of the inner cavity of the steaming and baking device and the pre-stored cavity image, and the pre-stored cavity image is collected when the inner cavity of the steaming and baking device is in a clean state;

[0203] Determine the current cleanliness of the inner cavity of the steaming and baking device based on the comparison result between the current image and the pre-stored cavity image;

[0204] If the current cleanliness is lower than the preset cleanliness, control the ultrasonic device to continuously operate for a preset duration based on the descaling parameters indicated by the target cleaning strategy until it is detected that the cleanliness of the inner cavity of the steaming and baking device is greater than or equal to the preset cleanliness, and then control the ultrasonic device to stop operating. By specifying that the descaling continues for a certain period when the current cleanliness is lower than the preset cleanliness, the cleaning effect can be ensured and the normal operation of the device due to insufficient cleaning can be avoided. Specifically, the preset duration can be 1 - 3 minutes. Preferably, the preset duration is 1 - 2 minutes. More preferably, the preset duration is 1 minute.

[0205] In some embodiments, as Figure 9 shown, the specific process after controlling the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy includes:

[0206] S3: When the water volume in the steam generator meets the preset conditions, control the ultrasonic device to operate based on the descaling parameters indicated by the target cleaning strategy to perform ultrasonic oscillation treatment on the steam generator of the steaming and baking device;

[0207] S411: Obtain the cavity image of the inner cavity of the steaming and baking device and the pre - stored cavity image, and determine the current cleanliness of the inner cavity of the steaming and baking device based on the comparison result between the current image and the pre - stored cavity image;

[0208] S412: Whether the current cleanliness is greater than or equal to the preset cleanliness. If so, execute step S5; if not, then execute step S413;

[0209] S413: Control the ultrasonic device to continuously operate for a preset time.

[0210] An embodiment of the present invention also provides a descaling control device applied to a steaming and baking device.

[0222] In some embodiments, the device further includes: a time supplement module, configured to, if the current cleanliness is lower than the preset cleanliness, control the ultrasonic device to continuously run for a preset duration based on the descaling parameters indicated by the target cleaning strategy until it is detected that the cleanliness of the inner cavity of the steaming and baking device is greater than or equal to the preset cleanliness, and then control the ultrasonic device to stop running.

[0223] In some embodiments, the time supplement module includes:
