[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0053] The embodiment of the present invention provides a control method and a steam oven. Based on a cleaning instruction, the steam oven is controlled to enter the first stage of the cleaning mode, and the cooking chamber of the steam oven is actively heated by a steam generating device. After the first stage, the steam oven enters the second stage of the cleaning mode, and the solenoid valve provided in the air inlet channel is opened and the exhaust fan is started to clean the steam oven. During the cleaning process of the steam oven, the mode and stage switching is realized by temperature and humidity, and the start and stop of the solenoid valve and the exhaust fan are automatically controlled accordingly. In this way, the tedious operation of manually cleaning the steam oven is effectively avoided, and the cleaning efficiency is significantly improved. In addition, the timing of issuing the cleaning instruction can be set according to the demand, and the steam oven is cleaned in a timely and effective manner, which effectively avoids the cross-flavor between foods of different cooking batches or different cooking types and the food odor pollution caused by the cross-flavor, and significantly improves the user experience.

[0054] Figure 1 and Figure 2is a schematic diagram of an application scenario of the control method of the steam oven according to an embodiment of the present application, such as Figure 1 As shown, the steam oven has a cooking cavity 106, a steam generating device 107, an air inlet channel 109 and an exhaust channel 104, the air inlet channel 109 has a solenoid valve 101, and the exhaust channel 104 has an exhaust fan 102. Further, the air inlet channel 109 may include an air inlet pipe, and the air inlet channel 109 is also provided with an air inlet port 108. The exhaust channel 104 is also provided with an air vent 103. In addition, the steam oven is also provided with a sealing door 105, which is used to form the cooking cavity 106 with the steam oven body (not shown in the figure). When the steam oven is used to perform cooking work, the steam generating device 107 heats the cooking cavity 106 to increase the internal temperature of the cooking cavity 106, thereby achieving the cooking purpose, and the solenoid valve 101 is closed at this time.

[0055] According to an embodiment of the present invention, a control method embodiment of a steam oven is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0056] In this embodiment, a control method for a steam oven is provided, which can be used for the above-mentioned steam oven. The steam oven has a cooking cavity 106, a steam generating device 107, an air intake channel 109 and an exhaust channel 104. The air intake channel 109 has a solenoid valve 101, and the exhaust channel 104 has an exhaust fan 102. Figure 3 is a flow chart of a control method of a steam oven according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0057] Step S301, based on the cleaning instruction, control the steam oven to enter the first stage of the cleaning mode. In the first stage, control the steam generating device to heat the cooking cavity to a first preset temperature.

[0058] In some optional embodiments of the present invention, the cleaning instruction can be triggered by the user clicking a setting button to send it to the steam oven controller after the cooking operation. It can also be a cleaning instruction that is automatically triggered after the steam oven executes the set program. For example, after each cooking, the cleaning instruction is triggered by closing the airtight door of the steam oven. It can also be triggered at a set time point or every set time period, for example, the cleaning instruction is triggered at 22:00 every Sunday night, etc.

[0059] The key operation of the first stage of controlling the steam oven to enter the cleaning mode is: controlling the steam generating device to heat the cooking cavity to a first preset temperature.

[0060] Here, the first preset temperature may be 100°C. If the steam generating device is immediately turned off and no longer heated after the cooking cavity is heated to the first preset temperature, the temperature in the cooking cavity will begin to drop, and the cooking cavity may not be completely cleaned. Therefore, the cooking cavity may be heated to the first preset temperature and maintained for a set time, which may be 20 minutes. The steam generating device may be controlled to heat the cooking cavity to the first preset temperature again after the cooking cavity temperature drops to a set temperature value. Other applicable methods may also be used to control the steam generating device to heat the cooking cavity to the first preset temperature.

[0061] Step S302, after the first stage ends, control the steam oven to enter the second stage of the cleaning mode.

[0062] After the first stage is over, the key to controlling the steam oven to enter the second stage of the cleaning mode is to exhaust the gas in the cooking cavity and discharge it out of the cooking cavity. Therefore, the key operation of controlling the steam oven to enter the second stage of the cleaning mode is to make the exhaust channel unblocked and provide appropriate power to discharge the gas in the cooking cavity out of the cooking cavity.

[0063] Step S303, in the second stage, the solenoid valve is opened and the exhaust fan is started, and the temperature and / or humidity of the cooking cavity is detected.

[0064] Figure 4 FIG. 1 shows a schematic diagram of the airflow inside and outside the cooking cavity 106 after the solenoid valve 101 is opened and the exhaust fan 102 is started. Figure 4 As shown, after the control solenoid valve 101 is opened, the air outside the cooking cavity 106 enters the cooking cavity 106 through the solenoid valve 101, the air inlet pipe and the air inlet 108 in sequence. The air flows in the cooking cavity 106, and enters the exhaust passage 104 from the air vent 103 after passing through the cooking cavity 106. The exhaust passage 104 is a wind tube structure that is small in the front and large in the back. The size of the wind tube structure is similar to the side area of ​​the exhaust fan 102. Under the drive of the exhaust fan 102, the air flow speed inside the cooking cavity 106 gradually increases. Because the exhaust passage 104 is driven by the exhaust fan 102, the air inside the cooking cavity 106 forms a tangential airflow at the air vent 103, so that a negative pressure is formed at the lower end of the air vent 103, and the negative pressure further accelerates the air flow rate in the cooking cavity 106. As a result, the air in the exhaust passage 104 is quickly discharged to the outside of the cooking cavity 106 of the steam oven.

[0065] Furthermore, a temperature detection device (not shown in the figure) and a humidity detection device (not shown in the figure), such as a temperature sensor and a humidity sensor, may be configured in the vent 103. The temperature of the vent 103 may be collected by the temperature detection device, and the humidity of the vent 103 may be collected by the humidity detection device.

[0066] Step S304: Based on the temperature and / or humidity, control the solenoid valve and the exhaust fan to close.

[0067] By using the temperature of the vent collected by the temperature detection device and the humidity of the vent collected by the humidity detection device, it can be determined whether all the air in the cooking cavity is discharged out of the cooking cavity of the steam oven. More accurately, a more accurate determination can be made based on the temperature change rate of the temperature and the humidity change rate of the humidity.

[0068] The control method of the steam oven in the embodiment of the present invention controls the steam oven to enter the first stage of the cleaning mode based on the cleaning instruction, actively heats the cooking cavity of the steam oven through the steam generating device, and enters the second stage of the cleaning mode after the first stage, opens the solenoid valve provided in the air inlet channel and starts the exhaust fan to clean the steam oven. During the cleaning process of the steam oven, the mode and stage switching is achieved through the temperature and humidity, and the start and stop of the solenoid valve and the exhaust fan are automatically controlled accordingly. In this way, the tedious operation of manually cleaning the steam oven is effectively avoided, and the cleaning efficiency is significantly improved. In addition, the timing of issuing the cleaning instruction can be set according to the needs, and the steam oven can be cleaned in a timely and effective manner, effectively avoiding the cross-flavor between foods of different cooking batches or different cooking types and the food odor pollution caused by the cross-flavor, and significantly improving the user experience.

[0069] In this embodiment, a control method for a steam oven is provided, which can be used for the above-mentioned steam oven. The steam oven has a cooking cavity, a steam generating device, an air intake channel and an exhaust channel. The air intake channel has a solenoid valve 101, and the exhaust channel has an exhaust fan. Figure 5 is a flow chart of a control method of a steam oven according to an embodiment of the present invention. Figure 5 As shown, the process includes the following steps:

[0070] Step S501, based on the cleaning instruction, control the steam oven to enter the first stage of the cleaning mode. In the first stage, control the steam generating device to heat the cooking cavity to a first preset temperature.

[0071] In an optional implementation, in step S501, the following operations may be used to control the steam generating device to heat the cooking cavity to a first preset temperature:

[0072] Step S5011, controlling the steam generating device to repeatedly heat the cooking cavity to a first preset temperature, until the cooking cavity reaches the first preset temperature a preset number of times, and the first stage ends.

[0073] Specifically, step S5011 may include:

[0074] Step a1: after the steam generating device heats the cooking cavity to a first preset temperature, the steam generating device is turned off.

[0075] In an optional embodiment, the steam generating device may be turned off after the steam generating device heats the cooking cavity to the first preset temperature.

[0076] In another optional embodiment, after the steam generating device heats the cooking cavity to the first preset temperature, the steam generating device may continue to be controlled to operate until the first preset temperature is maintained for a fourth preset time, and then the steam generating device is turned off.

[0077] Here, the first preset temperature, the fourth preset time and other preset times and temperatures can be set according to actual needs, and the present invention is not limited to this.

[0078] The control method of the steam oven in the embodiment of the present invention continues to control the steam generating device to work for a fourth preset time after the steam generating device heats the cooking cavity to a first preset temperature, and then turns off the steam generating device, thereby fully ensuring that the first preset temperature is maintained in the cooking cavity, thereby effectively improving the cleanliness of the cooking cavity.

[0079] Step a2, when the temperature of the cooking cavity drops to a second preset temperature, reopening the steam generating device, wherein the second preset temperature is lower than the first preset temperature.

[0080] Specifically, the temperature of the cooking cavity can be detected in real time, and when the detected temperature reaches 100°C, the steam generating device is turned off, and when the detected temperature is lower than 80°C, the steam generating device is started again. In this way, the steam generating device is controlled to repeatedly heat the cooking cavity to the first preset temperature until the cooking cavity reaches the first preset temperature for a preset number of times, and the first stage ends. The preset number of times can be 2 times, 3 times, or other suitable times.

[0081] The control method of the steam oven according to the embodiment of the present invention repeatedly heats the cooking cavity to a first preset temperature through a steam generating device, thereby effectively improving the cleanliness of the cooking cavity.

[0082] Step S502, after the first stage ends, control the steam oven to enter the second stage of the cleaning mode.

[0083] For details, please see Figure 3 Step S301 of the illustrated embodiment will not be described in detail here.

[0084] Step S503, in the second stage, the solenoid valve is opened and the exhaust fan is started, and the temperature and / or humidity of the cooking cavity is detected.

[0085] For details, please see Figure 3 Step 301 of the illustrated embodiment will not be described in detail here.

[0086] Step S504: Based on the temperature and / or humidity, control the solenoid valve and the exhaust fan to close.

[0087] Specifically, step S504 includes:

[0088] Step S5041, determining a temperature change rate of the temperature based on the temperature, and / or determining a humidity change rate of the humidity based on the humidity.

[0089] In some optional embodiments of the present invention, the changing trend of temperature over time is the temperature changing rate, and the changing trend of humidity over time is the humidity changing rate.

[0090] Step S5042, controlling the solenoid valve and the exhaust fan to close based on the temperature change rate and / or the humidity change rate.

[0091] In an optional implementation, step S5042 may include:

[0092] Step b1, after the temperature change rate is less than the first preset curvature and the humidity change rate is less than the second preset curvature, control the solenoid valve and the exhaust fan to close.

[0093] Here, the first preset curvature and the second preset curvature may be equal or unequal, and both may be determined separately according to actual needs.

[0094] For example, the first preset curvature and the second preset curvature are both equal to 0.35. When the temperature change curvature is ≥ 0.35 or the humidity change curvature is ≥ 0.35, the steam oven is controlled to continue the second stage of the cleaning mode. When the temperature change rate is < 0.35 and the humidity change rate is < 0.35 for 2 minutes, the solenoid valve and the exhaust fan are controlled to be closed.

[0095] Here, you can also first close the solenoid valve, and then turn off the exhaust fan after a delay of 5 minutes to complete the second stage of the steam oven cleaning mode.

[0096] The control method of the steam oven in the embodiment of the present invention determines the temperature change rate based on the temperature, determines the humidity change rate based on the humidity, and controls the electromagnetic valve and the exhaust fan to be closed after the temperature change rate is less than the first preset curvature and the humidity change rate is less than the second preset curvature. The electromagnetic valve and the exhaust fan are controlled timely and effectively through quantifiable parameters such as the temperature and humidity of the cooking cavity of the steam oven, which significantly improves the controllability of the cleaning process, thereby effectively realizing the cleaning of the steam oven.

[0097] In another optional embodiment, when the temperature change rate is less than the first preset curvature for a first duration that reaches a first set time and the humidity change rate reaches the second preset curvature for a second duration that reaches a second set time, the solenoid valve and the exhaust fan are controlled to close, thereby implementing the above step b1.

[0098] For example, the first preset curvature and the second preset curvature are both equal to 0.35. When the temperature change curvature is ≥ 0.35 or the humidity change curvature is ≥ 0.35, the steam oven is controlled to continue the second stage of the cleaning mode. After the temperature change rate is less than 0.35 for 2 minutes and the humidity change rate is less than 0.35 for 2 minutes, the solenoid valve and the exhaust fan are controlled to be closed.

[0099] According to the control method of the steam oven of the embodiment of the present invention, when the temperature change rate is less than the first preset curvature for a first duration that reaches the first set time and the humidity change rate reaches the second preset curvature for a second duration that reaches the second set time, it indicates that the temperature and humidity are basically stable. At this time, the solenoid valve and the exhaust fan are promptly controlled to be closed, which effectively reduces the energy consumption of the exhaust fan and significantly improves the cleaning efficiency.

[0100] Figure 6 Another application scenario of the control method of the steam oven according to the embodiment of the present invention is shown. Figure 6 As shown, the steam oven to which the control method for the steam oven according to the embodiment of the present invention is applied further includes an electric heating tube 110, which is arranged inside the cavity of the steam oven.

Figure 7 is a flow chart of a control method of a steam oven according to an embodiment of the present invention. Figure 7 As shown, the process includes the following steps:

[0102] Step S701, based on the cleaning instruction, control the steam oven to enter the first stage of the cleaning mode. In the first stage, control the steam generating device to heat the cooking cavity to a first preset temperature.

[0103] In an optional embodiment, in step S701, controlling the steam generating device to heat the cooking cavity to a first preset temperature can be achieved by the following operations: after controlling the electric heating tube to heat the cooking cavity to a third preset temperature, controlling the steam generating device to heat the cooking cavity to the first preset temperature, wherein the third preset temperature is lower than the first preset temperature.

[0104] For example, the first preset temperature may be 100°C, and the third preset temperature may be 60°C. Here, an electric heating tube may be used to heat the cooking cavity to 60°C, and then a steam heating device may be used to further heat the cooking cavity to 100°C.

[0105] The control method of the steam oven in the embodiment of the present invention heats the cooking cavity by means of an electric heating tube arranged inside the cavity of the steam oven, thereby effectively improving the heating efficiency of the cooking cavity and thus significantly improving the cleaning efficiency of the steam oven.

[0106] Step S702, after the first stage ends, control the steam oven to enter the second stage of the cleaning mode.

[0107] Step S703, in the second stage, the solenoid valve is opened and the exhaust fan is started, and the temperature and / or humidity of the cooking cavity is detected.
