[0002] With people's pursuit of healthy eating, steamed food is becoming increasingly popular because it better preserves the flavor and nutrients of food. Consequently, household appliances such as steam ovens and steam ovens are becoming more and more popular. However, in order to maintain the cavity temperature during the cooking process, steam ovens or steam ovens often introduce a lot of steam, which produces excess condensation. This not only affects the taste of the food but also increases the difficulty of cleaning the equipment, resulting in a poor user experience. Summary of the Invention

[0034] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

[0035] Traditional steam ovens use a thermostat to control the steam generator's on / off state to achieve the desired cooking temperature for their steaming and quick-steaming methods. To maintain this temperature, excessive steam is often introduced, resulting in humidity levels inside the cavity far exceeding the ideal humidity for steaming food. This causes excess condensation to drip onto the food during cooking, affecting its appearance and taste. Furthermore, after steaming, excess condensation accumulates on the cavity walls and sealing rings, and the reflux tank collects this wastewater, increasing the difficulty of cleaning.

[0036] In view of this, please refer to Figure 1This application provides a control method for a kitchen appliance. The kitchen appliance can operate in a second mode and / or a first mode to cook food, wherein the first mode includes steaming, and the second mode includes at least one cooking mode such as grilling, hot air, or microwave. The control method includes:

[0037] 01: When the kitchen appliance reaches the set temperature in the first mode, determine the humidity level inside the cavity;

[0038] 02: Based on changes in humidity levels, control the kitchen appliances to switch between the first and second modes to complete the food cooking process.

[0039] Please combine Figure 2 This application also provides a control device 10. The control device 10 includes a judgment module 11 and a control module 12. The control device 10 can be installed inside a kitchen appliance or connected externally to the kitchen appliance. This application will describe the case where the control device 10 can be installed inside a kitchen appliance.

[0040] Step 11 can be implemented by the judgment module 11, and step 12 can be implemented by the control module 12.

[0041] In other words, the judgment module 11 is used to determine the humidity value inside the cavity when the kitchen appliance operates in the first mode and reaches the set temperature. The control module 12 is used to control the kitchen appliance to switch between the second mode and the first mode according to the change in humidity value, so as to complete the food cooking process.

[0042] Specifically, the kitchen appliance can be a steam oven, or other appliances that can operate in either a second mode or a first mode to cook food, or appliances that can operate in both a second mode and a first mode simultaneously to cook food. This application uses a steam oven as an example to illustrate this.

[0043] When the kitchen appliance is a steam oven, the first mode includes steam cooking, and the second mode includes at least one cooking mode such as grilling, convection, or microwave. The following explanation uses steaming as the first mode and grilling as the second mode as an example.

[0044] When the steam oven reaches the set temperature in its first mode (steaming mode), it first activates the steaming mode to reach a balanced temperature. Then, the judgment module 11 can monitor and judge the humidity value inside the steam oven cavity in real time. Since the humidity value inside the cavity is necessarily relatively high before reaching the balanced temperature, detecting the humidity value when the steaming mode reaches the balanced temperature can improve the accuracy of the humidity value judgment without increasing energy consumption. The typical set temperature is 90℃ to 120℃.

[0045] The judgment module 11 may include a humidity detector or other instruments capable of detecting the humidity value inside the cavity of the steam oven, and there are no limitations on this. For example, a humidity detector can be installed inside the steam oven, and the humidity detector can be connected to a computer to obtain the humidity value inside the steam oven cavity in a timely manner.

[0046] While the steam oven continues to operate at a set temperature of 90℃ to 120℃ for 0 to 12 minutes, the control module 12 can control the steam oven to intelligently switch between the second mode and the first mode based on the change in humidity value judged by the judgment module 11, thereby completing the food cooking process.

[0047] The control method and control module of this application determine the humidity value inside the cavity of the kitchen appliance and control the intelligent switching of the working mode of the kitchen appliance according to the change of humidity value. Thus, without increasing energy consumption, it achieves no condensation or dripping during the cooking process, and effectively reduces the excess moisture in the cavity after steaming, resulting in better food taste and reducing the difficulty of cleaning the equipment.

[0048] Please see Figure 3 In some implementations, step 02 includes:

[0049] 021: When the humidity value reaches the first preset humidity value, control the kitchen appliances to switch from the first mode to the second mode.

[0050] Please combine Figure 2 Step 021 can be implemented by the control module 12. That is to say, the control module 12 is used to control the kitchen appliances to switch from the first mode to the second mode when the humidity value reaches the first preset humidity value.

[0051] Specifically, the first preset humidity value can be assumed to be value A, such as value A being 100%RH-90%RH.

[0052] Understandably, when steaming food, the steam oven first starts its steaming mode to reach a balanced temperature, generally set at 90-120℃, and continues to run for 0-10 minutes. When the humidity sensor inside the cavity detects that the humidity value inside the cavity reaches value A (100%RH-90%RH), the first module (steaming mode) is stopped and the second mode (baking mode) is switched. This allows the oven to switch to baking mode in time when too much moisture is generated during cooking to prevent excessive moisture production.

[0053] Please see Figure 4 In some implementations, step 02 includes:

[0054] 022: When the humidity value drops from the first preset humidity value to the second preset humidity value, control the kitchen appliances to switch from the second mode to the first mode.

[0055] 023: When the humidity value rises from the second preset humidity value to the third preset humidity value, the kitchen appliances are controlled to switch from the first mode to the second mode.

[0056] 024: When the humidity value drops from the third preset humidity value to the second preset humidity value, the kitchen appliance is controlled to switch from the second mode to the first mode, wherein the first preset humidity value is greater than or equal to the third preset humidity value.

[0057] Please combine Figure 2 Steps 022, 023 and 024 can be implemented by the control module 12.

[0058] In other words, the control module 12 is used to control the kitchen appliance to switch from the second mode to the first mode when the humidity value drops to the second preset humidity value. The control module 12 is also used to control the kitchen appliance to switch from the first mode to the second mode when the humidity value rises to the third preset humidity value. The first preset humidity value is greater than or equal to the third preset humidity value.

[0059] Specifically, the first preset humidity value can be assumed to be value A, such as A being 100%RH to 90%RH. The second preset humidity value can be assumed to be value B, which can be 50%RH to 70%RH. The third preset humidity value can be assumed to be value C, where value A is greater than or equal to value C, for example, value C being 70%RH to 90%RH. In this case, the relationship between the three preset humidity values ​​is A ≥ C ≥ B.

[0060] When the humidity value inside the cavity drops from value A to value B, the control module 12 can control the steam oven to switch from baking mode to steaming mode to replenish the steam inside the cavity.

[0061] When the humidity value rises from B to C, the control module 12 can control the steam oven to switch from steaming mode to baking mode to remove excess moisture.

[0062] When the humidity value drops from C to B, the control module 12 can control the kitchen appliance to switch back from baking mode to steaming mode. By controlling the intelligent switching between steaming and baking modes of the steam oven through the control module 12, the entire cooking process is completed.

[0063] Specifically, this application uses the optimal and maximum humidity values ​​required for steaming food as standard values. That is, the aforementioned value A can be set as the humidity value when the steam oven initially starts steaming and reaches the equilibrium temperature, value B can be set as the optimal humidity value required for steaming food, and value C can be set as the maximum humidity value required for steaming food, with value A ≥ value C ≥ value B. Values ​​A, B, and C have all been measured through numerous experiments, and the values ​​of A, B, and C will vary depending on the type of food.

[0064] The specific workflow is as follows: When steaming food, first start the steam oven in steam mode, reach the set temperature of 90-120℃, and continue running for 0-10 minutes. When the humidity value reaches A, stop steaming and switch to baking mode, setting the temperature back to 90-120℃ to maintain the required temperature for steaming. When the humidity sensor detects that the cavity humidity has dropped to the minimum humidity value D (D is the minimum humidity value required for steaming food), switch back to steam mode to replenish steam, bringing the cavity humidity to value C, and then switch back to baking mode. When the cavity humidity drops to the minimum humidity value D, switch back to steam mode. In this way, the intelligent control module for humidity detection regulates the intelligent switching between steaming and baking modes, ultimately completing the entire steaming process.

[0065] More specifically, in one example, when steaming seafood in a steam oven, the steam oven is first activated in steam mode. Once the set temperature of 100℃ to 120℃ is reached, and the humidity value is A, the steam mode is switched to baking mode, with the temperature also set to 100℃ to 120℃ to maintain the required temperature for steaming. When the humidity sensor detects that the cavity humidity has dropped to a value B, the oven switches back to steam mode to replenish steam, bringing the cavity humidity to a value C, and then switches back to baking mode. When the humidity sensor detects that the cavity humidity has dropped to a value B, the oven switches back to steam mode. The intelligent control module of the humidity sensor regulates the intelligent switching between steaming and baking modes, ultimately completing the entire steaming process. In this mode, value A equals value C.

[0066] In another example, when steaming grains, chicken, beef, etc. in a steam oven, the steam oven is first started in steam mode, reaching the set temperature of 90℃ to 120℃, and continues to run for 1-10 minutes. When the humidity value reaches A, the steam mode is stopped and switched to baking mode, with the temperature set to 90℃ to 120℃ to maintain the required temperature for steaming. When the humidity sensor detects that the cavity humidity has dropped to humidity value B, it switches back to steam mode to replenish steam, bringing the cavity humidity to value C, and then switches back to baking mode. When the humidity sensor detects that the cavity humidity has dropped to humidity value B, it switches back to steam mode. The intelligent control module of the humidity sensor regulates the intelligent switching between steaming and baking modes to complete the entire steaming process. In this mode, value A > value C.

[0067] In addition, since the control module 12 controls the intelligent switching of modes during the cooking process of the steam oven, the cooking time for food to be cooked is fixed. Therefore, when cooking the same food, the energy consumption of cooking in the intelligent switching mode described above is the same as the energy consumption in the normal mode. Therefore, the control method of the kitchen appliance of this application can achieve the goal of no condensation and no dripping during the cooking process without increasing energy consumption.

[0068] Please see Figure 5 In some implementations, the control method includes:

[0069] 03: Within the preset time limit for the end of the current work cycle, detect the working mode of the kitchen appliances;

[0070] 04: If the kitchen appliance is in the first mode, control the kitchen appliance to switch from the first mode to the second mode. When the humidity value drops to the fourth preset humidity value, keep the kitchen appliance in the second mode and turn on the first mode at the first frequency.

[0071] Please combine Figure 6 The control device 10 for kitchen appliances also includes a mode detection module 13.

[0072] Step 03 can be implemented by the pattern detection module 13, and step 04 can be implemented by the control module 12.

[0073] That is, the mode detection module 13 is used to detect the working mode of the kitchen appliance within a preset time after the end of the current work cycle. The control module 12 is used to control the kitchen appliance to switch from the first mode to the second mode if the kitchen appliance is in the first cooking mode. When the humidity value drops to the fourth preset humidity value, the kitchen appliance is kept in the second mode and the first mode is turned on at the first frequency.

[0074] Specifically, the preset time can be any value between 0 and 5 minutes. That is to say, if the mode detection module 13 detects that the cavity is in steaming mode 0 to 5 minutes before the end of cooking, the control module 12 can control the steam oven to disconnect the steaming mode and turn on the grilling mode.

[0075] When the humidity sensor detects that the humidity inside the steam oven has dropped to the fourth preset humidity value, assuming the fourth preset humidity value is D, and D is between 30% and 50% RH, the grilling mode remains on, and the steaming mode is activated at the first frequency to supply steam to the food. The first frequency can be 1 to 5 seconds of steam every 60 seconds. Activating the steaming mode at the first frequency reduces the operating time of the steam generator in the kitchen appliance, allowing for full utilization of the water in the water tank and thus reducing the frequency of water tank refills.

[0076] In this way, the humidity inside the cavity can be further controlled within a preset time when the cooking process is about to end, ensuring that no excess condensation will accumulate on the inner wall of the cavity and the sealing ring after the cooking process is over. This can effectively prevent excess condensation from dripping onto the food and affecting its appearance and taste.

[0077] Specifically, the fourth preset humidity value (i.e., the D value) can be set as the minimum humidity value required for steaming food, and the A value ≥ C value ≥ B value ≥ D value.

[0078] In addition, in other embodiments of this application, the kitchen appliance of this application can set different on / off ratios of steaming and baking modes according to the characteristics of different foods, so as to reduce energy consumption and improve efficiency when steaming the same food.

[0079] Turning on the steaming mode at the first frequency can reduce the working time of the steam generator in the kitchen appliance, making full use of the water in the water tank and thus reducing the frequency of water tank refills.

[0080] Please see Figure 7 In some implementations, the control method includes:

[0081] 03: Within the preset time limit for the end of the current work cycle, detect the working mode of the kitchen appliances;

[0082] 05: If the kitchen appliance is in the first mode, control the kitchen appliance to switch from the first mode to the second mode. When the humidity value drops to the fourth preset humidity value, control the kitchen appliance to alternate between the first mode and the second mode within a preset cycle.

[0083] Please combine Figure 6 and Figure 2 Step 03 can be implemented by the mode detection module 13, and step 05 can be implemented by the control module 12. That is, the mode detection module 13 is used to detect the working mode of the kitchen appliance within a preset time after the end of the current working cycle. The control module 12 is used to control the switch to the second mode if the working mode is the first mode, and to control the kitchen appliance to work alternately in the first mode and the second mode within the preset cycle when the humidity value drops to the fourth preset humidity value.

[0084] Specifically, the preset time can be any value between 0 and 5 minutes. That is to say, if the mode detection module 13 detects that the cavity is in steaming mode 0 to 5 minutes before the end of cooking, the control module 12 can control the steam oven to disconnect the steaming mode and turn on the grilling mode.

[0085] When the humidity detector detects that the humidity inside the cavity has dropped to the fourth preset humidity value, which is assumed to be value D, and where value D is between 30% and 50% RH, the control module 12 can also control the steaming mode and the grilling mode to alternately operate within a preset cycle. For example, if the preset cycle is 60 seconds, the control module 12 can control the steam oven to operate in grilling mode for 40 to 60 seconds and in steaming mode for 0 to 20 seconds every 60 seconds. It should be noted that the shorter steaming mode operation time compared to the baking mode reduces the operating time of the steam generator in the kitchen appliance, allowing for full utilization of the water in the water tank and thus reducing the frequency of water tank refills.

[0086] In this way, the humidity inside the cavity can be further controlled within a preset time when the cooking process is about to end, ensuring that no excess condensation will accumulate on the inner wall of the cavity and the sealing ring after the cooking process is over. This can effectively prevent excess condensation from dripping onto the food and affecting its appearance and taste.

[0087] It should be noted that whether to choose to keep the kitchen appliances working in the second mode (such as baking mode) and start the first mode (such as steaming mode) at the first frequency, or to choose to have the kitchen appliances work alternately in the second mode and the first mode within a preset cycle, can be determined according to the type of food and user needs.

[0088] Please see Figure 8 In some implementations, the control method includes:

[0089] 03: Within the preset time limit for the end of the current work cycle, detect the working mode of the kitchen appliances;

[0090] 06: If the kitchen appliance is in the second mode, keep the kitchen appliance working in the second mode. When the humidity value drops to the fourth preset humidity value, control the kitchen appliance to turn on the first mode at the first frequency.

[0091] Please combine Figure 6 and Figure 2 Step 03 can be implemented by the pattern detection module 13, and step 06 can be implemented by the control module 12.

[0092] That is, the mode detection module 13 is used to detect the working mode of the kitchen appliance within a preset time range after the end of the current work cycle. The control module 12 is used to keep the kitchen appliance working in the second mode if it is in the second mode, and to control the kitchen appliance to start working in the first mode at a first frequency when the humidity value drops to a fourth preset humidity value.

[0093] Specifically, the preset time can be any value between 0 and 5 minutes. That is to say, if the mode detection module 13 detects that the cavity is in baking mode 0 to 5 minutes before the end of cooking, the control module 12 can control the oven to keep the grilling mode on and working.

[0094] When the humidity detector detects that the humidity inside the cavity has dropped to a fourth preset humidity value, which is assumed to be value D, and where value D is between 30% and 50% RH, the control module 12 can also control the oven to keep the grilling mode on and activate the steaming mode at a first frequency, thereby supplying steam to the food. The first frequency can be 1 to 5 seconds of steam every 60 seconds. Activating the steaming mode at the first frequency reduces the operating time of the steam generator in the kitchen appliance, allowing for full utilization of the water in the water tank and thus reducing the frequency of water tank refills.

[0095] In this way, the humidity inside the cavity can be further controlled within a preset time when the cooking process is about to end, ensuring that no excess condensation will accumulate on the inner wall of the cavity and the sealing ring after the cooking process is over. This can effectively prevent excess condensation from dripping onto the food and affecting its appearance and taste.

[0096] Please see Figure 9 The control methods include:

[0097] 03: Within the preset time limit for the end of the current work cycle, detect the working mode of the kitchen appliances;

[0098] 07: If the kitchen appliance is in the second mode, keep the kitchen appliance working in the second mode. When the humidity value drops to the fourth preset humidity value, control the kitchen appliance to alternate between the first mode and the second mode within a preset cycle.

[0099] Please combine Figure 6 and Figure 2 Step 03 can be implemented by the pattern detection module 13, and step 07 can be implemented by the control module 12.

[0100] In other words, the mode detection module 13 is used to detect the working mode of kitchen appliances within a preset time range at the end of the current work cycle.

[0101] The control module 12 is used to keep the kitchen appliance working in the second mode if the kitchen appliance is in the second mode, and to control the kitchen appliance to work alternately in the first mode and the second mode within a preset cycle when the humidity value drops to the fourth preset humidity value.

[0102] Specifically, the preset time can be any value between 0 and 5 minutes. That is to say, if the mode detection module 13 detects that the cavity is in baking mode 0 to 5 minutes before the end of cooking, the control module 12 can control the oven to keep the grilling mode on and working.

[0103] When the humidity detector detects that the humidity inside the cavity has dropped to the fourth preset humidity value, which is assumed to be value D (30% RH to 50% RH), the control module 12 can also control the steam oven to alternate between steaming and baking modes within a preset cycle. For example, the preset cycle can be 60 seconds, meaning that every 60 seconds, the steam oven will operate in baking mode for 40 to 60 seconds and in steaming mode for 0 to 20 seconds. It should be noted that the shorter steaming time compared to baking reduces the operating time of the steam generator in the kitchen appliance, allowing for more efficient use of the water in the water tank and thus reducing the frequency of water replenishment.

[0104] In this way, the humidity inside the cavity can be further controlled within a preset time when the cooking process is about to end, ensuring that no excess condensation will accumulate on the inner wall of the cavity and the sealing ring after the cooking process is over. This can effectively prevent excess condensation from dripping onto the food and affecting its appearance and taste.

[0105] Please see Figure 10 In some implementations, step 02 includes:

[0106] 025: When the humidity value reaches the fifth preset humidity value, control the kitchen appliances to simultaneously start working in the first mode and the second mode;

[0107] 026: Reduce the steam generation efficiency of kitchen appliances in the first mode and / or increase the grilling power in the second mode.

[0108] Please combine Figure 2 Steps 025 and 026 can be implemented by the control module 12.

[0109] That is, the control module 12 is used to control the operation to start in both the second mode and the first mode when the humidity value reaches the fifth preset humidity value; to increase the grilling power of the kitchen appliance in the second mode and / or reduce the steam generation efficiency in the first mode.

[0110] Specifically, when the humidity detector detects that the humidity value inside the cavity is the fifth preset humidity value, the control module 12 can control the steam oven to simultaneously start and operate the steaming mode and baking mode. The fifth preset humidity value can be the same as the third preset humidity value (C value), which can be between 70%RH and 90%RH. Alternatively, the fifth preset humidity value can be a different value from the third preset humidity value, meaning it can be set according to user needs.

[0111] Next, the control module 12 can reduce the steam generation efficiency when the steam oven is only in steaming mode; or increase the grilling power when the steam oven is only in baking mode; or, when the steam oven is in both steaming and baking modes, simultaneously increase the grilling power and reduce the steam generation efficiency.

[0112] This prevents excess condensation from accumulating on the inner wall of the cavity and inside the sealing ring, and also prevents excess condensation from dripping onto the food, affecting its appearance and taste.

[0113] In other embodiments of this application, the amount of steam or the steam power can be reduced to prevent excess condensate from accumulating on the inner wall of the cavity and inside the sealing ring, thus preventing excess condensate from dripping onto the food and affecting its appearance and taste.

[0114] Please see Figure 11 In some implementations, the control method further includes:

[0115] 027: If the humidity value drops to the sixth preset humidity value, increase the steam generation efficiency of the kitchen appliances in the first mode and / or reduce the grilling power in the second mode.

[0116] Please combine Figure 2 Step 027 can be implemented by control module 12.

[0117] That is, if the humidity value drops to the sixth preset humidity value, the control module 12 is used to reduce the grilling power of the kitchen appliance in the second mode and / or increase the steam generation efficiency in the first mode.

[0118] Specifically, at this time, when the humidity detector detects that the humidity value inside the cavity has dropped to the sixth preset humidity value, the control module 12 can control the steaming mode and baking mode of the steam oven to be turned on and operated simultaneously. The sixth preset humidity value can be the same as the second preset humidity value (B value), and the B value can be 50%RH-70%RH. The sixth preset humidity value can also be a different value from the second preset humidity value, that is, the sixth preset humidity value can also be set according to user needs.

[0119] Next, the control module 12 can increase the steam generation efficiency when the steam oven is only in steaming mode; or reduce the grilling power when the steam oven is only in baking mode; or, when the steam oven is in both steaming and baking modes, reduce the grilling power and increase the steam generation efficiency at the same time.

[0120] This prevents excess condensation from accumulating on the inner wall of the cavity and inside the sealing ring, and also prevents excess condensation from dripping onto the food, affecting its appearance and taste.

[0121] In other embodiments of this application, the amount of steam or the steam power can be increased to prevent excess condensate from accumulating on the inner wall of the cavity and inside the sealing ring, thus preventing excess condensate from dripping onto the food and affecting its appearance and taste.

[0122] Furthermore, through steps 025, 026, and 027 above, the steam oven can maintain the cavity humidity value between the sixth preset humidity value (value B) and the fifth preset humidity value (value C). The entire cooking process described above involves simultaneous steaming and grilling modes, avoiding frequent switching between these modes, thus reducing the risk of damage to the steam oven and extending its lifespan.

[0123] Please see Figure 12 This application also provides a readable storage medium 200, which includes a computer program 210 and a processor 220. When the computer program 210 is executed by one or more processors 220, it implements the method of any of the above embodiments.

[0124] The computer-readable storage medium of this application can determine the humidity value inside the cavity of a kitchen appliance and control the intelligent switching of the working mode of the kitchen appliance based on the change of humidity value. This achieves the goal of preventing condensation and dripping during cooking without increasing energy consumption, and effectively reduces the excess moisture in the cavity after steaming, resulting in better food taste and reducing the difficulty of cleaning the equipment.

[0125] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
