Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

The embodiment of the application provides a control method of an oven, which can be applied to the controller 7 in the oven 100. Fig. 11 is a schematic flow chart of a cooking process of an oven according to an embodiment of the present application. As shown in fig. 11, the control method may include the steps of:

s101, controlling the steaming oven to start to operate a cooking program.

When a user needs to cook food by using the steaming oven, a controller of the steaming oven needs to acquire a cooking program corresponding to the food to be cooked, so as to control the steaming oven to cook the food to be cooked according to the cooking program corresponding to the food to be cooked.

It will be appreciated that the cooking program for different foods to be cooked may be different, for example, the cooking program for baked bread and baked fish may be different. When the food to be cooked is cooked, a user can select a proper cooking program according to the attribute of the food to be cooked so as to obtain a good cooking effect.

For example, a user may input a cooking program of food to be cooked to the steam oven by voice using a voice recognition function of the steam oven. The voice acquisition device of the steaming oven acquires voice instructions of a user and recognizes the voice instructions of the user so as to acquire a cooking program of food to be cooked.

S102, if the cooking program comprises a door opening heat dissipation step, acquiring the temperature in the cooking cavity in real time.

The controller judges whether the cooking program comprises a door opening heat dissipation step or not before controlling the steaming oven to run the cooking program, and controls the temperature sensor to detect the temperature in the cooking cavity in real time when the cooking program comprises the door opening heat dissipation step. The controller can acquire the temperature in the cooking chamber in real time through the temperature sensor.

It can be understood that the temperature in the cooking cavity can be obtained in real time, the working state of the steaming and baking oven can be monitored, and the cooking program can be corrected according to the working state of the steaming and baking oven, so that a good cooking effect can be obtained.

And S103, if the temperature in the cooking cavity is greater than or equal to a first preset temperature corresponding to the door opening heat dissipation step, controlling the driving device to drive the door body to open.

When the temperature in the cooking cavity obtained by the controller reaches a first preset temperature corresponding to the heat dissipation step, the controller can control the driving device to drive the door body to rotate, so that the door body of the steaming and baking box is opened.

It should be noted that, in different cooking procedures, the first preset temperature corresponding to the step of opening the door and radiating heat may be different. For example, the first preset temperature corresponding to the step of opening the door and radiating the heat in the cooking process corresponding to the grilled fish may be different from the first preset temperature corresponding to the step of opening the door and radiating the heat in the cooking process corresponding to the grilled bread.

In some embodiments, if the temperature in the cooking chamber is greater than or equal to a first preset temperature corresponding to the step of opening the door and dissipating heat, the driving device is controlled to drive the door to open, which specifically includes:

if the temperature in the cooking cavity is greater than or equal to the first preset temperature corresponding to the door opening and heat dissipation step, judging whether the door opening times in the process of running the cooking program of the steaming oven are smaller than the preset times corresponding to the door opening and heat dissipation step; if yes, the driving device is controlled to drive the door body to open.

The controller counts the door opening times in the process of the steaming oven running the cooking program, and before the controller controls the driving device to drive the door body to open, the controller judges whether the door opening times in the process of the steaming oven running the cooking program are smaller than the preset times corresponding to the door opening heat dissipation steps, and when the door opening times are smaller than the preset times, the controller controls the driving device to drive the door body to open.

It should be noted that the first preset door opening times corresponding to the door opening heat dissipation steps corresponding to different cooking programs may be different. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

When the door opening times are smaller than the preset times corresponding to the door opening heat dissipation steps, the fact that the steaming oven does not finish the door opening heat dissipation steps included in the cooking program is indicated. In this case, the controller may control the driving device to drive the door body to open so as to continue to complete the door opening and heat dissipation steps included in the cooking process.

When the door opening times are greater than or equal to the preset times corresponding to the heat dissipation steps, the fact that the steaming oven has completed the door opening heat dissipation steps included in the cooking program is indicated. Under the condition, the controller can control the steaming oven to stop executing the door opening and heat dissipation steps, and the driving device is not controlled to drive the door body to open.

In some embodiments, in the process of the steaming oven running the cooking program, if the door opening times reach the preset times, a prompt message is sent out.

When the door opening times reach the preset times, the step of opening the door and radiating heat contained in the cooking program is finished by the steaming oven. In this case, the controller may send a prompt message to alert the user that the door opening heat dissipation step has been completed.

For example, the prompt issued by the controller may include one or more of the following.

Mode 1, the controller controls the voice prompt device to play the first prompt message.

The content played by the voice prompt device may be "the step of opening the door and radiating heat is completed, please confirm", wherein the voice of the voice prompt device playing the prompt information may be a preset voice when the steaming and baking oven leaves the factory, or may be various voice packets downloaded by the user for the steaming and baking oven through the internet.

Optionally, the controller may control the voice prompt device to stop playing the prompt information after receiving the confirmation operation of the user.

And 2, the controller sends prompt information to the terminal equipment of the user through the communication interface.

The controller can also send prompt information to the terminal equipment (such as a mobile phone) of the user through the communication interface so as to prompt the user that the door opening and heat dissipation steps in the cooking program are completed.

Fig. 12 is a schematic diagram illustrating a display of prompt information by a terminal device according to an embodiment of the present application, as shown in fig. 12. The terminal device receives the prompt message sent from the steaming box through Wi-Fi network or Bluetooth, which is "the step of opening the door and radiating heat is completed, please confirm-! ".

And S104, if the temperature in the cooking cavity is smaller than a second preset temperature corresponding to the door opening heat dissipation step, controlling the driving device to drive the door body to be closed.

Wherein the second preset temperature is less than the first preset temperature. It is understood that the second preset temperature is a target temperature to be reached by opening the door of the steaming oven for heat dissipation.

When the temperature in the cooking cavity is smaller than the second preset temperature corresponding to the door opening heat dissipation step, the purpose of opening the door and dissipating heat is achieved, and at the moment, the controller controls the driving device to drive the door body to be closed, so that the steaming oven continues to operate the cooking program, and cooking is completed.

In some embodiments, if the temperature in the cooking chamber is greater than or equal to the first preset temperature corresponding to the door opening heat dissipation step, the controller controls the driving device to drive the door body to open by a target angle.

Wherein the target angle is determined from a difference between the first preset temperature and the second preset temperature.

The target angle is, for example, a first preset angle when the difference between the first preset temperature and the second preset temperature is greater than or equal to a preset temperature difference. When the difference between the first preset temperature and the second preset temperature is smaller than the preset temperature difference, the target angle is the second preset angle. Wherein the first preset angle is larger than the second preset angle.

That is, when the steaming oven performs door opening heat dissipation, the controller can control the door opening angle of the steaming oven according to the temperature value which is reduced as required. It can be understood that the larger the temperature value to be reduced is, the larger the corresponding door opening angle is; the smaller the temperature value to be reduced, the smaller the corresponding door opening angle. Therefore, the cooling rate in the cooking cavity can be matched with the temperature value to be reduced, the cooking time is shortened, and the use experience of a user is improved.

The first preset angle may be, for example, a maximum angle that can be reached when the driving device drives the door body to open. The second preset angle may be any one of a fifth, a quarter, a third and a half of the first preset angle, and may be specifically selected according to practical situations, which is not specifically limited in the present disclosure. For example, the second preset angle is one third of the first preset angle.

In some embodiments, after the cooking is completed, if the temperature in the cooking chamber is greater than the third preset temperature, the controller controls the driving device to drive the door to open.

Illustratively, the third predetermined temperature is any one of 30 ℃, 35 ℃, 40 ℃, 45 ℃, and 50 ℃. Specifically, the selection may be performed according to actual situations, and this disclosure is not limited specifically.

The third preset temperature may be preset when the steaming oven leaves the factory, or may be preset by a user through a user input port.

It can be appreciated that when the steaming oven finishes cooking, the temperature in the cooking chamber is high, and at this time, the user directly opens the door body of the steaming oven, and the user can be scalded, so that the personal safety of the user is damaged. Through detecting the temperature in the cooking cavity to when the temperature in the cooking cavity is greater than the third and predetermines the temperature, control drive arrangement drive door body and open, can reduce the risk of scalding the user in advance to the cooking cavity, improve the safety in utilization of steaming and baking box.

On the basis, when the temperature in the cooking cavity is smaller than or equal to a third preset temperature, the controller can control the driving device to drive the door body to be closed. Thus, the heat preservation of the food is facilitated, and the use experience of a user is improved.

In some embodiments, after the driving device drives the door body to open, the plurality of reed pipes are disconnected, and the controller controls the driving device to retract the push rod.

It will be appreciated that when the reed switch is disconnected, the push rod of the drive means is shown separated from the door body. For example, human intervention, the door is opened. At this time, the driving device can not drive the door body to rotate any more. The driving device is controlled to retract the push rod, so that the push rod is protected, and the damage risk of the push rod is reduced.
