Generally speaking, the terms "comprising" and "including" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

The modules are merely illustrative, and different aspects of the apparatus and method may use different modules.

[0035] It should be understood that when a unit or module is described as "connected" or "coupled" to other units, modules or blocks, it may mean directly connected or coupled, or communicate with other units, modules or blocks, or there may be intermediate units, modules or blocks, unless the context clearly indicates otherwise. The term "and / or" as used herein may include any and all combinations of one or more of the related listed items.

[0036] The cooking control method of the steam oven provided by this application can be applied to the controller of the steam oven. The steam oven may further include a cabinet, a cabinet door, and a door control switch provided on the cabinet for detecting the state of the cabinet door. An inner container and a blower communicating with the inner container are provided in the cabinet. As Figure 1 shown, the position and specific structure of the blower in the steam oven are shown.

[0037] Wherein, the door control switch is used to detect the state of the cabinet door, including the open or closed state. The blower is used to blow dry air outside into the inner container of the cabinet. The blower is provided with different speed gears, such as low speed gear, medium speed gear and high speed gear speed gears. The higher the gear speed, the faster the blower blows dry air into the inner container and the faster the moisture exhaust speed.

[0038] As Figure 2 shown, the controller 200 is electrically connected to the door control switch 300 and the blower 100. The controller is used to obtain the state of the cabinet door detected by the door control switch; if the cabinet door is in the open state, the blower is controlled to operate at the highest gear power until after a first preset time when the door control switch detects that the cabinet door is in the closed state.

[0039] Considering that in the existing steam oven during the cooking process, when the cabinet door is opened and then closed, the air pressure in the inner container will increase. If the power of the blower is small at this time, resulting in the failure to timely exhaust the steam in the inner container, the steam in the inner container will backflow into the blower, posing a risk of causing failures of the blower and the steam oven.

[0040] To solve the above technical problems, an embodiment of this application provides a cooking control method for a steam oven, which is applied to the controller of the above-mentioned steam oven. As Figure 3 shown, the method includes the following steps:

[0041] S102: Obtain the state of the cabinet door detected by the door control switch.

[0042] Specifically, a door control switch is installed inside the box body of the steam oven. The door control switch can be used to detect the state of the box door during the steaming function cooking process of the steam oven, including the open state and the closed state, and send the state of the box door to the controller.

[0043] S104: If the box door is in the open state, control the blower to operate at the maximum power until a first preset time after the door control switch detects that the box door is in the closed state.

[0044] During the steaming function cooking process, if it is detected that the box door is opened, the controller controls the blower to operate at the maximum power. The blower is used to blow dry air outside into the inner container. The greater the power, the faster the moisture is discharged. During the steaming function cooking process, when the box door is opened and then closed, the air pressure in the inner container will increase. If the power of the blower is small at this time, the steam in the inner container will backflow into the blower. In this application, by increasing the operating power of the blower, the air pressure in the inner container is lower than the air pressure in the blower, so backflow will not occur. After that, the controller controls the blower to enter the normal operating state. If the blower operates at a low power before the box door is opened, continue to control the blower to operate at a low power after a first preset time when the box door is in the closed state.

[0045] Based on the above steps S102 - S104, in this embodiment, during the steaming function cooking process of the steam oven, the state of the box door detected by the obtained door control switch is judged; if the box door is in the open state, control the blower to operate at the maximum power until a first preset time after the door control switch detects that the box door is in the closed state, avoiding the risk of high-pressure steam backflowing into the blower at the moment of closing the door, and achieving a better safety effect.

[0046] Among them, the first preset time can be set according to actual needs. Exemplarily, the first preset time is set to 30 seconds. That is, during the cooking process, when the door control switch detects that the box door is in the open state, the controller controls the blower to operate at the maximum power, and when the door control switch detects that the box door is closed for 30 seconds, then controls the blower to enter the normal operating state.

[0047] In some embodiments, the method further includes: obtaining the difference between the current cooking time and the preset cooking time of the steam oven; if the difference is less than or equal to the time threshold, control the blower to operate at the maximum power for a second preset time, and the second preset time is greater than the time threshold.

[0048] Wherein, the time threshold and the second preset time can be set according to actual requirements, and the second preset time is greater than the time threshold. Exemplarily, the time threshold is set to 5 minutes and the second preset time is set to 10 minutes.

[0049] In this embodiment, when the steam function of the steam oven is turned on, the blower enters the steam function exhaust mode. In the early stage of cooking, the blower operates at a low power level to prevent steam from flowing back into the air duct; in the later stage of cooking, in order to minimize the influence of external air on the cavity temperature as much as possible, when the difference between the current cooking time and the preset cooking time is less than or equal to the time threshold, the controller controls the blower to operate at the highest power level for the second preset time. At this time, the moisture removal speed is the fastest, achieving the effect of discharging steam in advance and avoiding the risk of steam hitting the face when opening the oven door at the end of cooking.

[0050] In some embodiments, a humidity sensor is further provided in the inner container, and the method further includes: if the difference is greater than the time threshold, determining whether the humidity detected by the humidity sensor is greater than the humidity threshold; if so, controlling the blower to operate at the power corresponding to the preset gear, and the preset gear is determined based on the type of the food being cooked currently.

[0051] Wherein, the humidity sensor is used to detect the humidity of the inner container, and the controller is further used to obtain the humidity data detected by the humidity sensor in real time.

[0052] The preset gear is determined based on the type of the food being cooked currently. For example, for some roasted dishes with high humidity, high moisture removal requirements, and a lot of oil fume, the highest gear is used for moisture removal to achieve the best cooking effect of the food.

[0053] In this embodiment, when the difference between the current cooking time and the preset cooking time is greater than the time threshold, determining whether the humidity detected by the humidity sensor is greater than the humidity threshold. If so, it indicates that the humidity in the cavity is too high. At this time, the controller controls the blower to operate at the power corresponding to the preset gear for moisture removal to achieve the best cooking effect.

[0054] In some embodiments, a temperature sensor is further provided in the inner container. The temperature sensor is used to detect the temperature of the inner container, and the controller is further used to obtain the temperature data detected by the temperature sensor. The method further includes the following:

[0055] Based on the temperature detected by the temperature sensor, determining whether the steam oven has ended the temperature rise stage;

[0056] If so, determining whether the humidity detected by the humidity sensor is greater than the humidity threshold; otherwise, controlling the blower to operate at the lowest power level.

[0057] In this embodiment, the controller makes a judgment based on the temperature detected by the temperature sensor. If the temperature detected by the temperature sensor is greater than the temperature threshold, it is determined that the steam oven has ended the heating-up stage. After the steam oven ends the heating-up stage, a judgment is made based on the humidity detected by the humidity sensor. If the humidity detected by the humidity sensor is greater than the humidity threshold, it indicates that the humidity inside the cavity is too high. At this time, the controller controls the blower to operate at the highest gear to perform rapid dehumidification. If the humidity detected by the humidity sensor is less than or equal to the humidity threshold, indicating that the humidity inside the cavity is normal, the controller controls the blower to operate at the lowest gear.

[0058] Figure 4 It is a flowchart of the cooking control method for the steam oven in the first exemplary embodiment. As Figure 4 shown, the method includes the following steps:

[0059] S201, when the controller detects that the steam oven starts cooking, it controls the blower to operate at a low power level.

[0060] S202, the controller judges whether the temperature detected by the temperature sensor is greater than the temperature threshold to determine whether the steam oven has ended the heating-up stage.

[0061] S203, if the heating-up stage has ended, the controller judges whether the humidity detected by the humidity sensor is greater than the humidity threshold; if the heating-up stage has not ended, the controller continues to control the blower to operate at a low power level.

[0062] S204, if the humidity detected by the humidity sensor is greater than the humidity threshold, control the blower to operate at the highest gear, otherwise, control the blower to operate at the lowest power level.

[0063] S205, during the cooking process, the controller judges whether the difference between the current cooking time and the preset cooking time is less than or equal to the time threshold (5 minutes).

[0064] S206, if it is less, control the blower to operate at the highest power level for a second preset time (8 minutes).

[0065] During the process of steps S201 to S206, it also includes that the door control switch continuously detects the state of the oven door, and the controller is also used to obtain the state of the oven door detected by the door control switch; if the oven door is in the open state, control the blower to operate at the highest power level until the first preset time after the door control switch detects that the oven door is in the closed state, avoiding the risk of high-pressure steam backflow into the blower at the moment of closing the door, and achieving a better safety effect.

[0066] It should be understood that although the steps in the above flowchart are shown in sequence according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise clearly stated in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, at least a part of the steps in the above flowchart may include multiple steps or multiple stages. These steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed alternately or in turn with at least a part of other steps or steps or stages in other steps.

[0068] The controller is configured to obtain the state of the box door detected by the door control switch; if the box door is in an open state, the controller controls the blower to operate at the highest gear power until a first preset time after the door control switch detects that the box door is in a closed state.

[0069] In the steam oven according to the embodiment of the present application, by providing a door control switch for detecting the state of the box door on the box body, during the cooking process, the controller obtains the state of the box door detected by the door control switch in real time; if the box door is in an open state, the controller controls the blower to operate at the highest gear power until a first preset time after the door control switch detects that the box door is in a closed state. By controlling the blower to operate at the highest gear power from the moment the box door is in an open state until a first preset time after the box door is in a closed state, pressure relief measures are taken for the cavity in a timely manner, avoiding the risk of high-pressure steam backflow into the blower at the moment of closing the door, and achieving a better safety effect.

[0070] In one embodiment, the controller is further configured to obtain the difference between the current cooking time and the preset cooking time of the steam oven; if the difference is less than or equal to a time threshold, the controller controls the blower to operate at the highest gear power for a second preset time, and the second preset time is greater than the time threshold.
