[0045] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0046] The terms "first", "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0047] The steam oven is an electric appliance capable of steaming and baking food. The steam oven includes a box body, a steam baking inner container, a water tank, a heating device and a steam generator. The steam baking inner container, the heating device, the water tank and the steam generator are all arranged in the box body. The heating device can heat the steam baking inner container.

[0048] When food needs to be baked, the food is placed in the steam baking inner container, and the heating device heats the steam baking inner container, so that the food can be baked.

[0049] When food needs to be steamed, the food is placed in the steam baking inner container, and the steam generator is controlled to convert the water in the water tank into high-temperature steam and then enter the steam baking inner container, so that the food in the steam baking inner container can be steamed.

[0050] The steam oven provided in the embodiments of the present application improves the safety factor of the steam oven by remote starting protection mechanism, and makes up for the defects that may be caused by remote starting of the steam oven. As shown in the figure, Figure 1 The steam oven includes:

[0051] The steam baking inner container 10 has a heating cavity formed inside;

[0052] The heating pipe 20 is used to heat the heating cavity;

[0053] The power board 30 is used to supply power to the steam oven;

[0054] The cooling fan 40 is used to cool the power board 30;

[0055] The communication module 50 is used to establish a communication connection with the control terminal of the user;

[0056] a discrimination module 60, configured to discriminate whether there is preset operation after the steaming oven is started;

[0057] a controller 70, configured to:

[0058] start a preset self-checking program to perform self-checking on the steaming oven and start timing when receiving a starting instruction sent by the control terminal of the user;

[0059] start the cooling fan 40 and start the heating pipe 20 to preheat if the self-checking is normal;

[0060] stop the steaming oven if the timing reaches a first preset time length and no discrimination result sent by the discrimination module 60 that there is preset operation is received.

[0061] In the embodiment, the control terminal can be a mobile phone, a tablet computer, a smart wearable device (such as a smart bracelet or a smart watch), etc. The control terminal is installed with an application program that can send a control instruction to the steaming oven. The communication module 50 can be a device component with functions of communication and data processing, etc. and can be a WiFi module, a 2 / 3 / 4 / 5G module or a NB-IoT module. Normally, the user will perform some preset operation after the steaming oven is started, such as opening the door to put in the food to be steamed and baked, etc. The discrimination module 60 can discriminate whether there is preset operation after the steaming oven is started to determine whether the user has actually operated the steaming oven after the steaming oven is started.

[0062] The preset self-checking program is pre-stored in the controller 70. When the controller 70 receives the starting instruction sent by the control terminal through the communication module 50, the preset self-checking program is started to perform self-checking on the steaming oven to detect whether the steaming oven can be normally started. The timing is started at the same time when the preset self-checking program is started. If the self-checking is normal, it indicates that the steaming oven can be normally started. The cooling fan 40 is started to cool the power board 30 to ensure that the hardware and software of the steaming oven can work normally. Then the heating pipe 20 is started to preheat. If the timing reaches the first preset time length and no discrimination result sent by the discrimination module 60 that there is preset operation is received, it indicates that the steaming oven has not been actually operated by the user after the steaming oven is started. It can be a misoperation of the user. At this time, to ensure safety, the steaming oven is stopped.

[0063] Optionally, the first preset time length can be 10 minutes.

[0064] To further improve the safety of the steaming oven, the controller 70 is further configured to:

[0065] maintain the temperature if the timing does not reach the first preset time length, no discrimination result is received and the temperature of the heating cavity reaches a preset proportion of the user demand temperature.

[0066] In the embodiment, before the timing reaches the first preset time length and the discrimination result is not received, if the temperature of the heating cavity reaches the preset proportion of the user demand temperature, the power of the heating pipe 20 is controlled to maintain the temperature in the heating cavity, so as to ensure that the temperature of the heating cavity is not too high.

[0067] Optionally, the preset proportion can be 90%. For example, if the user demand temperature is 100℃, when the temperature of the heating cavity reaches 90℃, the temperature of the heating cavity is maintained at 90℃.

[0068] In order to remind the user to perform the related operation in time after the steam oven is started, in some embodiments of the present application, the steam oven further comprises a buzzer, and the controller 70 is further configured to:

[0069] If the timing reaches the second preset time length and does not reach the first preset time length and the discrimination result is not received, the buzzer is started, and / or the control terminal is sent the prompt information that the user is not detected.

[0070] In the embodiment, if the timing reaches the second preset time length and does not reach the first preset time length and the discrimination result is not received, it is indicated that the user has been waited for a period of time, and the preset operation of the steam oven after the steam oven is started is not detected. In order to remind the user that the steam oven has been started, the buzzer is started, and / or the control terminal is sent the prompt information that the user is not detected.

[0071] Optionally, the difference between the first preset time length and the second preset time length can be 1 minute.

[0072] In order to inform the user that the steam oven fails to start, in some embodiments of the present application, the controller 70 is further configured to:

[0073] Before the steam oven stops working, the control terminal is sent the prompt information that the starting fails.

[0074] In order to further improve the user experience, in some embodiments of the present application, the controller 70 is further configured to:

[0075] If the self-check is abnormal, the control terminal is sent the prompt information that the equipment is abnormal;

[0076] If the timing does not reach the first preset time length and the discrimination result is received, the control terminal is sent the prompt information that the starting succeeds.

[0077] In order to ensure the reliability of the discrimination module 60, in some embodiments of the present application, the discrimination module 60 is an infrared detection module, or an open door detection module, or an open door key.

[0078] In this embodiment, if the steaming oven is provided with an infrared detection module, whether the user has performed post-start operation on the steaming oven can be detected by the infrared probe; if the steaming oven is not provided with an infrared detection module, whether the user has opened the door can be detected by the door opening detection module or the door opening key, so as to determine whether the user has performed post-start operation on the steaming oven.

[0079] By applying the above technical solution, the steaming oven comprises a steaming oven liner, a heating pipe, a power board, a cooling fan, a communication module, a discrimination module and a controller, the controller is configured to: when receiving a start instruction sent by a control terminal of a user, starting a preset self-checking program to perform self-checking on the steaming oven and starting timing; if the self-checking is normal, starting the cooling fan and starting the heating pipe to preheat; if the timing reaches a first preset time length and no discrimination result of the preset operation is received from the discrimination module, stopping the steaming oven from working, so that the possibility of user misoperation can be avoided, and the reliability and safety of remote start of the steaming oven are improved.

[0080] In order to further illustrate the technical idea of the present application, the technical solution of the present application will be described in combination with specific application scenarios.

[0081] The present application embodiment provides a start control method of a steaming oven, as shown in Figure 2 The method comprises the following steps:

[0082] Step S101, APP remote start instruction is issued.

[0083] The mobile phone APP issues a remote start instruction to the controller of the steaming oven.

[0084] Step S102, device self-checking.

[0085] Step S103, whether the device is normal, if yes, step S104 is performed, otherwise, step S105 is performed.

[0086] Step S104, starting the cooling fan.

[0087] The cooling fan is started to dissipate heat from the power board, so as to ensure the reliability and safety of the device hardware.

[0088] Step S105, feeding back device abnormality.

[0089] The controller feeds back device abnormality to the mobile phone APP.

[0090] Step S106, starting the heating pipe to preheat.

[0091] Before the remote start protection mechanism is discriminated to be normal, if the temperature of the heating cavity of the steaming oven reaches 90% of the user's demand and is maintained, the discrimination result of the remote protection mechanism is waited.

[0092] Step S107, the remote start protection mechanism is determined to be normal, if yes, execute step S109, otherwise execute step S108.

[0093] Step S108, the start fails.

[0094] The oven stops working, and the controller sends a start failure prompt information to the mobile phone APP.

[0095] Step S109, the start succeeds.

[0096] The oven starts normally, and the controller sends a start success prompt information to the mobile phone APP.

[0097] The control principle of the remote start protection mechanism is as shown in Figure 3 , including the following steps:

[0098] Step S201, the remote start protection mechanism starts.

[0099] Step S202, whether the infrared detection function is available, if yes, execute step S204, otherwise execute step S203.

[0100] The remote protection mechanism is determined by the existing hardware of the steaming oven, and most of the current intelligent steaming ovens have infrared probes. For ovens without infrared probes, the start can be determined by door opening detection or door opening key.

[0101] Step S203, the user opens the door or confirms the door opening key.

[0102] Step S204, the infrared probe detects.

[0103] Step S205, whether it is overtime, if yes, execute step S206, otherwise execute step S207.

[0104] After the user issues a remote start instruction through the mobile phone APP, the timer starts timing. If the infrared probe does not detect the presence of the user or the user does not confirm through the door opening detection or the door opening key within a certain time (such as 10 minutes), the device reminds the user to confirm through the buzzer and the mobile phone APP 1 minute in advance. If the user still does not confirm after the timeout, it is defaulted as a false operation.

[0105] Step S206, the remote start protection mechanism is determined to be abnormal.

[0106] Step S207, the remote start protection mechanism is determined to be normal.

[0107] By applying the above technical solution, the existing hardware function of the steaming oven can be expanded, the possibility of user misoperation can be avoided, the reliability and safety factor of the device use can be improved, and the defects that may be caused by the remote start of the steaming oven can be compensated.

[0108] The embodiment of the present application also provides a starting control method of the steam oven, wherein the steam oven comprises a discrimination module for discriminating whether there is a preset operation after the steam oven is started, and the method comprises the following steps: Figure 4
