[0001] This application relates to the technical field of steam cooking appliances, and particularly to a steam oven and its control method. Background Art

[0002] The heating sources of existing steam ovens are often distributed at the top or the back of the inner cavity of the steam oven. Thus, when the steam oven is baking food, if the placed food is divided into upper and lower layers, often due to the influence of the position of the heating source of the steam oven, the food on the top layer is heated too fast, while the food at the bottom is blocked, resulting in a temperature lower than that of the food on the top. As a result, the food is unevenly heated. If the baking work continues, the food on the top will be burnt while the food at the bottom is not cooked. Summary of the Invention

It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0044] Please refer to Figures 1 to 3 below, and Figures 1 - 3 will be used to describe the technical solutions of the present application in detail.

[0045] An embodiment of the present application provides a steam oven, as Figures 1 to 3 shown. Specifically, the steam oven includes a steam oven cabinet 1, a ripeness detection device 2, a control device, and an upper steam baking device 3 and a lower steam baking device 4 arranged in the steam oven cabinet 1.

[0046] Among them, the upper steaming and baking device 3 and the lower steaming and baking device 4 are both arranged on the moving mechanism 7. The positions of the upper steaming and baking device 3 and the lower steaming and baking device 4 can be moved through the movement of the moving mechanism 7. The moving mechanism 7 is electrically connected to the control device, and the control device is arranged outside the steaming oven housing 1; the maturity detection device 2 is arranged on the inner side wall of the steaming and baking door body 11 in the steaming oven housing 1. The maturity detection device 2 is electrically connected to the control device. The maturity detection device 2 is used to detect the first maturity data of the food to be steamed and baked on the upper steaming and baking device 3 and the second maturity data of the food to be steamed and baked on the lower steaming and baking device 4, so that the control device controls the movement of the moving mechanism 7 based on the first maturity data and the second maturity data transmitted by the maturity detection device 2.

[0047] In the embodiment of the present application, the movement of the moving mechanism 7 can drive the upper steaming and baking device 3 and the lower steaming and baking device 4 to move. It can be understood that the multiple steaming and baking units 5 in the upper steaming and baking device 3 can move to the position of the lower steaming and baking device 4, and the multiple steaming and baking units 5 in the lower steaming and baking device 4 can move to the position of the upper steaming and baking device 3. Furthermore, the multiple steaming and baking units 5 on the upper layer can move to the lower layer, and the multiple steaming and baking units 5 on the lower layer can move to the upper layer. Further, the maturity detection device 2 can detect the first maturity data of the food to be steamed and baked on the upper steaming and baking device 3 and the second maturity data of the food to be steamed and baked on the lower steaming and baking device 4, and transmit the detected first maturity data and second maturity data to the control device, so that the control device controls the movement of the moving mechanism 7 based on the first maturity data and the second maturity data to drive the upper and lower steaming and baking devices to move, thereby avoiding the situation that the food on the fixed two-layer baking trays is unevenly heated, resulting in the food on the top being burned and the food on the bottom being undercooked, and improving the steaming and baking accuracy.

[0048] In a specific embodiment, the maturity detection device 2 can be a camera or other imaging device. The first maturity data can be the color data detected on the surface of the food to be steamed and baked on the upper steaming and baking device 3, and the second maturity data can be the color data detected on the surface of the food to be steamed and baked on the lower steaming and baking device 4. It can be understood that the maturity detection device 2 can respectively detect the color data on the surface of the food to be steamed and baked on the upper steaming and baking device 3 and the lower steaming and baking device 4, and then determine the position data of the movement of the moving mechanism 7 driving the upper steaming and baking device 3 and the lower steaming and baking device 4 according to the color data on the surface of the food to be steamed and baked on the corresponding layer.

[0049] In a specific implementation manner, such as Figure 2As shown in the figure, the maturity detection device 2 includes a first maturity detection unit 21 and a second maturity detection unit 22. Among them, the first maturity detection unit 21 is arranged on the inner side wall of the steaming and baking door body 11, and at one end close to the top edge of the steaming and baking door body 11. The detection port of the first maturity detection unit 21 is arranged towards the upper-layer steaming and baking device 3. The second maturity detection unit 22 is arranged on the inner side wall of the steaming and baking door body 11 and is located in the middle of the steaming and baking door body 11. The detection port of the second maturity detection unit 22 is arranged towards the lower-layer steaming and baking device 4.

[0050] Specifically, the first maturity detection unit 21 is used to detect the first maturity data of the food to be steamed and baked on the upper-layer steaming and baking device 3, that is, the color data on the surface of the food to be steamed and baked on the upper-layer steaming and baking device 3. Further, by arranging the first maturity detection unit 21 at one end of the inner side wall of the steaming and baking door body 11 close to the top edge of the steaming and baking door body 11, and the detection port of the first maturity detection unit 21 is arranged towards the upper-layer steaming and baking device 3, it is convenient to improve the detection accuracy of the first maturity data of the food to be steamed and baked on the upper-layer steaming and baking device 3. Further, the second maturity detection unit 22 is used to detect the second maturity data of the food to be steamed and baked on the lower-layer steaming and baking device 4, that is, the color data on the surface of the food to be steamed and baked on the lower-layer steaming and baking device 4. Further, by arranging the second maturity detection unit 22 in the middle of the steaming and baking door body 11, and the detection port of the second maturity detection unit 22 is arranged towards the lower-layer steaming and baking device 4, it is convenient to improve the detection accuracy of the second maturity data of the food to be steamed and baked on the lower-layer steaming and baking device 4.

[0051] In actual application, the detection area of the first maturity detection unit 21 is Figure 2 the upper-middle dotted line area, and the detection area of the second maturity detection unit 22 is Figure 2 the lower-middle dotted line area, that is, the first maturity detection unit 21 is used to detect the first maturity data of the food to be steamed and baked on multiple steaming and baking units 5 in the upper-layer steaming and baking device 3, and the second maturity detection unit 22 is used to detect the second maturity data of the food to be steamed and baked on multiple steaming and baking units 5 in the lower-layer steaming and baking device 4.

[0052] In a specific embodiment, as Figure 1 and Figure 3 shown, the upper-layer steaming and baking device 3 includes multiple steaming and baking units 5, and the lower-layer steaming and baking device 4 includes multiple steaming and baking units 5. Among them, multiple steaming and baking units 5 in the upper-layer steaming and baking device 3 and multiple steaming and baking units 5 in the lower-layer steaming and baking device 4 are both arranged on the moving mechanism 7. The moving mechanism 7 is wound around the steaming oven frame body 1 in a rectangle. The moving mechanism 7 is used to drive multiple steaming and baking units 5 in the upper-layer steaming and baking device 3 and multiple steaming and baking units 5 in the lower-layer steaming and baking device 4 to move counterclockwise or clockwise.

[0053] Specifically, asFigure 1 As shown, the moving mechanism 7 is wound in a rectangular shape within the steam oven housing 1. It can be understood that the moving mechanism 7 can move in accordance with the layout direction of the moving mechanism 7. That is to say, the moving mechanism 7 can move counterclockwise or clockwise. When the moving mechanism 7 moves counterclockwise or clockwise, it can drive the upper steam baking device 3 and the lower steam baking device 4 to move, so as to change the relative position between the upper steam baking device 3 and the lower steam baking device 4, facilitating the steam baking of the food to be steam-baked on the upper steam baking device by the steam baking element 8 located at the top within the steam oven housing 1. Furthermore, when the color data on the surface of the food to be steam-baked on the upper steam baking device meets the preset color condition, the moving mechanism 7 can be controlled to move, so as to change the relative position between the upper steam baking device 3 and the lower steam baking device 4. As a result, the lower steam baking device is moved to the upper layer, and the food to be steam-baked on the steam baking device moved to the upper layer approaches the steam baking element 8, facilitating the steam baking of the food to be steam-baked with a lower degree of maturity. Moreover, it can be ensured that the color data on the surfaces of the food to be steam-baked on the upper and lower steam baking devices gradually tends to be consistent, that is, the food to be steam-baked on the upper and lower steam baking devices can mature synchronously, thereby avoiding the situation where the food at the top is burnt while the food at the bottom is undercooked due to uneven heating of the food on the two fixed baking trays, and improving the steam baking accuracy.

[0054] It should be noted that, as Figure 3 shown, the steam baking element 8 is arranged at the top within the steam oven housing 1. The steam baking element 8 is used for steam-baking the food within the steam oven housing 1. In a specific embodiment, the steam baking element 8 can be a heating element. Preferably, the heating element is a heating tube. Consequently, the food to be steam-baked on the upper steam baking device 3 closer to the steam baking element 8 matures earlier, and the food to be steam-baked on the lower steam baking device 4 farther from the steam baking element 8 matures later. And in this application, by setting the first maturity detection unit 21 to detect the first maturity data of the food to be steam-baked on the upper steam baking device 3, and setting the second maturity detection unit 22 to detect the second maturity data of the food to be steam-baked on the lower steam baking device 4, the control module can control the moving mechanism 7 to move according to the first maturity data and the second maturity data, so as to ensure that the food to be steam-baked on the upper and lower steam baking devices has the same or similar maturity.

[0055] In a specific implementation manner, the steam baking element 8 extends along the top of the steam oven housing 1. One end of the steam baking element 8 extends to the edge of the steam baking unit 5 near one inner side wall of the steam oven housing 1, and the other end of the steam baking element 8 extends to the edge of the steam baking unit 5 near the other inner side wall of the steam oven housing 1.

[0056] In an embodiment of the present application, one end of the steaming and baking member 8 extends to the edge of the steaming and baking unit 5 near the inner side wall of one side of the steaming and baking oven housing 1, and the other end of the steaming and baking member 8 extends to the edge of the steaming and baking unit 5 near the inner side wall of the other side of the steaming and baking oven housing 1, so as to heat the food to be steamed and baked on the upper steaming and baking unit 5 by using the steaming and baking member 8, and further ensure that the ripeness degrees of all the foods to be steamed and baked on the multiple steaming and baking units 5 on the upper layer are the same.

[0057] In some embodiments, such as Figure 1 and Figure 3 shown, the upper steaming and baking device 3 includes 3 steaming and baking units 5, and the lower steaming and baking device 4 includes 3 steaming and baking units 5. Among them, the steaming and baking unit 5 can be a baking tray. There is a preset interval between the 3 steaming and baking units 5 in the upper steaming and baking device 3, between the 3 steaming and baking units 5 in the lower steaming and baking device 4, and between the steaming and baking unit 5 in the upper steaming and baking device 3 and the steaming and baking unit 5 in the lower steaming and baking device 4. That is, the 6 steaming and baking units 5 are independent structures for respectively containing the foods to be steamed and baked. Further, the first ripeness detection unit 21 is used to detect the color data on the surfaces of the foods to be steamed and baked on the 3 steaming and baking units 5 on the upper layer, and the second ripeness detection unit 22 is used to detect the color data on the surfaces of the foods to be steamed and baked on the 3 steaming and baking units 5 on the lower layer. Further, the control module compares the color data on the surfaces of the foods to be steamed and baked on the 3 steaming and baking units 5 on the upper layer with the depth of the color data on the surfaces of the foods to be steamed and baked on the 3 steaming and baking units 5 on the lower layer, and controls the movement of the moving mechanism 7 according to the comparison result, so that the multiple steaming and baking units 5 on the moving mechanism 7 move in sequence, and further ensure that the ripening times of the foods to be steamed and baked on the multiple steaming and baking units 5 are equal.

[0058] In some embodiments, the upper steaming and baking device 3 includes 3 steaming and baking units 5, the lower steaming and baking device 4 includes 2 steaming and baking units 5 and a vacant position. Or, the upper steaming and baking device 3 includes 2 steaming and baking units 5 and a vacant position, and the lower steaming and baking device 4 includes 3 steaming and baking units 5.

[0059] In actual application, the way for the moving mechanism 7 to drive the multiple steaming and baking units 5 to move can be as follows. The first way is that through the movement of the moving mechanism 7, the positions of the 3 steaming and baking units 5 in the upper steaming and baking device 3 and the 3 steaming and baking units 5 in the lower steaming and baking device 4 can be exchanged and then fixed. Specifically, all 3 steaming and baking units 5 in the upper steaming and baking device 3 are moved to the positions of the 3 steaming and baking units 5 in the lower steaming and baking device 4, and all 3 steaming and baking units 5 in the lower steaming and baking device 4 are moved to the positions of the 3 steaming and baking units 5 in the upper steaming and baking device 3 and then fixed. In a specific embodiment, the moving process can be referred to Figure 3 wherein, Figure 3A1, A2, A3, B1, and B2 refer to the food to be steamed and roasted. The second method is that the moving mechanism 7 drives the three steaming and roasting units 5 in the upper steaming and roasting device 3 and the three steaming and roasting units 5 in the lower steaming and roasting device 4 to move slowly and uniformly until the steaming and roasting is completed.

[0060] In a specific embodiment, as Figure 1 shown, the steam oven housing 1 is further provided with a plurality of fixing members 9, and the plurality of fixing members 9 are arranged in one-to-one correspondence with the plurality of steaming and roasting units 5; wherein, one end of the fixing member 9 is arranged on the first moving part, the other end of the fixing member 9 is arranged on the second moving part, the fixing member 9 penetrates through the steaming and roasting unit 5, and is fixedly connected to the steaming and roasting unit 5.

[0061] In the embodiment of the present application, by arranging one end of the fixing member 9 on the first moving part, the other end of the fixing member 9 on the second moving part, and the fixing member 9 penetrating through the steaming and roasting unit 5, it is convenient to ensure that the placing surface of the steaming and roasting unit 5 is always on the upper side during the movement. That is to say, during the process of the moving mechanism 7 driving the plurality of steaming and roasting units 5 to move, it is necessary to ensure that the plurality of steaming and roasting units 5 are always horizontal. That is, the fixing member 9 of the fixed moving mechanism 7 and the steaming and roasting unit 5 can provide the supporting force for the steaming and roasting unit 5 to ensure that during the movement of the moving mechanism 7, the placing surfaces of the plurality of steaming and roasting units 5 are always horizontal, so as to avoid the situation that the food to be steamed and roasted falls during the steaming and roasting process.

[0062] In a specific embodiment, the width of the fixing member 9 is less than the width of the steaming and roasting unit 5, and the thickness of the fixing member 9 is less than the thickness of the steaming and roasting unit 5.

[0063] Specifically, the width of the fixing member 9 can be equal to half of the width of the steaming and roasting unit 5, and the thickness of the fixing member 9 is equal to half of the thickness of the steaming and roasting unit 5. Among them, the material of the fixing member 9 can be the same as or different from that of the steaming and roasting unit 5. Exemplarily, the material of the steaming and roasting unit 5 is stainless steel or enamel. Furthermore, the material of the fixing member 9 can be any one of stainless steel and enamel, or other materials with high temperature resistance and corrosion resistance, which are not specifically limited herein.

[0064] In some embodiments, a driving mechanism is further provided on the outer side wall of the steam oven housing 1. The driving shaft of the driving mechanism is connected to the moving mechanism 7, and the control end of the driving mechanism is connected to the control module. Furthermore, the control module can drive the moving mechanism 7 to move through the driving mechanism, so as to drive the plurality of steaming and roasting units 5 to move clockwise or counterclockwise.

[0065] In the embodiments of the present application, by evenly spacing a plurality of steaming and baking units 5 on a moving mechanism 7 wound in a rectangle within a steaming and baking oven housing 1, when the driving mechanism drives the moving mechanism 7 to move, the plurality of steaming and baking units 5 can be driven to move clockwise or counterclockwise, thereby realizing uniform heating of the foods to be steamed and baked on the upper and lower layers of the plurality of steaming and baking units 5 and improving the steaming and baking accuracy.

[0066] In a specific embodiment, the steaming and baking unit 5 can be a steaming baking tray. By evenly spacing a plurality of steaming baking trays on the moving mechanism 7, separate steaming and baking of a plurality of foods to be steamed and baked can be realized. At the same time, it is also convenient for the steaming and baking unit 5 to move along the moving mechanism 7. Further, by winding the moving mechanism 7 in a rectangle within the steaming and baking oven housing 1, the moving mechanism 7 can move clockwise or counterclockwise under the drive of the driving mechanism, and then drive the plurality of steaming and baking units 5 to move clockwise or counterclockwise, thereby realizing uniform heating of the foods to be steamed and baked on the upper and lower layers of the plurality of steaming and baking units 5.

[0067] In actual applications, the moving mechanism 7 is fixedly connected to the steaming and baking unit 5. During the movement of the moving mechanism 7, the steaming and baking unit 5 can move synchronously with the moving mechanism 7, thereby realizing uniform heating of the foods to be steamed and baked on the steaming and baking unit 5. In some embodiments, the moving mechanism 7 can be a moving mechanism with a moving chain or a conveying device to facilitate stable clockwise or counterclockwise movement.

[0068] In a specific embodiment, the distance from one side edge of the moving mechanism 7 wound in a rectangle within the steaming and baking oven housing 1 to the inner side wall of the steaming and baking oven housing 1 is greater than or equal to half of the width of the steaming and baking unit 5.

[0069] Specifically, during the movement of the moving mechanism 7, by setting the distance from one side edge of the moving mechanism 7 to the inner side wall of the steaming and baking oven housing 1 to be greater than or equal to half of the width of the steaming and baking unit 5, it is ensured that during the movement, the inner side wall of the steaming and baking oven housing 1 will not interfere with the movement of the steaming and baking unit 5.

[0070] It should be noted that the middle parts of both ends of the steaming and baking unit 5 are fixedly connected to the moving mechanism 7. Further, if the distance from one side edge of the moving mechanism 7 to the inner side wall of the steaming and baking oven housing 1 is greater than or equal to half of the width of the steaming and baking unit 5, the inner side wall of the steaming and baking oven housing 1 will not prevent the normal movement of the steaming and baking unit 5, which helps to realize uniform heating of the plurality of steaming and baking units 5.

[0071] In a specific embodiment, the driving mechanism is a driving motor, and the driving motor is used to drive the moving mechanism 7 at a constant speed. Specifically, the driving motor drives the moving mechanism 7 at a constant speed to facilitate uniform heating of the foods to be steamed and baked on the plurality of steaming and baking units 5.

[0072] In another specific embodiment, the driving mechanism is a driving motor, and the driving motor is used to intermittently drive the moving mechanism 7.

[0073] Specifically, the interval duration for the driving motor to drive the moving mechanism 7 to move can be 30 seconds, 1 minute, 2 minutes, 3 minutes, 5 minutes, etc. Preferably, the interval duration for the driving motor to drive the moving mechanism 7 to move is 1 minute. Furthermore, by intermittently driving the moving mechanism 7 to move clockwise or counterclockwise by the driving motor, it can be ensured that the heating duration of the food to be steamed and baked on each steaming and baking unit 5 is equal, so as to facilitate the uniform heating of the food to be steamed and baked on multiple steaming and baking units 5.

[0074] In an alternative embodiment, the moving mechanism 7 includes a first moving part and a second moving part arranged in parallel; wherein, the first moving part is arranged on the side close to the steaming and baking door in the steaming oven housing 1, and the second moving part is arranged on the side far from the steaming and baking door in the steaming oven housing 1. The steaming and baking unit 5 is arranged between the first moving part and the second moving part, and the first moving part and the second moving part move synchronously.

[0075] In the embodiment of the present application, both the first moving part and the second moving part are wound in a rectangular shape inside the steaming oven housing 1, and the first moving part and the second moving part are arranged opposite to each other, and the size and dimensions of the first moving part and the second moving part are equal, so as to facilitate the synchronous movement of the first moving part and the second moving part. Furthermore, when the first moving part and the second moving part move synchronously, they can drive the steaming and baking unit 5 located between the first moving part and the second moving part to move, which helps to ensure the stable movement of the steaming and baking unit 5.

[0076] In a specific embodiment, as Figure 1 shown, the steaming oven further includes a plurality of weight detection devices 6, and the plurality of weight detection devices 6 are respectively arranged on the upper steaming and baking device 3 and the lower steaming and baking device 4; wherein, the plurality of weight detection devices 6 are all electrically connected to the control device. The weight detection device 6 corresponding to the upper steaming and baking device 3 is used to detect the first weight data of the food to be steamed and baked on the upper steaming and baking device 3 and transmit the first weight data to the control device. The weight detection device 6 corresponding to the lower steaming and baking device 4 is used to detect the second weight data of the food to be steamed and baked on the lower steaming and baking device 4 and transmit the second weight data to the control device, so that the control device controls the heating duration of the steaming and baking part 8 at the top inside the steaming oven housing 1 based on the first weight data and the second weight data.

[0077] In the embodiment of the present application, weight detection devices 6 are respectively arranged on the upper-layer steaming and baking device 3 and the lower-layer steaming and baking device 4, so as to use the weight detection device 6 corresponding to the upper-layer steaming and baking device 3 to detect the first weight data of the food to be steamed and baked on the upper-layer steaming and baking device 3, and the weight detection device 6 corresponding to the lower-layer steaming and baking device 4 to detect the second weight data of the food to be steamed and baked on the lower-layer steaming and baking device 4, so that the control device controls the heating duration of the steaming and baking part 8 at the top inside the steaming oven housing 1 based on the first weight data and the second weight data, so as to accurately control the heating duration of the steaming and baking part 8 according to the weight data detected by the weight detection device 6, and improve the steaming and baking accuracy.

[0078] It should be noted that the first weight data is the weight data of the food to be steamed and baked on the upper-layer steaming and baking device 3 detected by the steaming oven before steaming and baking. It can be understood that the first weight data is the weight data of the food to be steamed and baked corresponding to each of the multiple steaming and baking units 5 in the upper-layer steaming and baking device 3. The second weight data is the weight data of the food to be steamed and baked on the lower-layer steaming and baking device 4 detected by the steaming oven before steaming and baking. It can be understood that the second weight data is the weight data of the food to be steamed and baked corresponding to each of the multiple steaming and baking units 5 in the lower-layer steaming and baking device 4. In actual applications, the first weight data and the second weight data are equal, or the difference between the first weight data and the second weight data meets a preset difference condition. Among them, the preset difference condition can be less than or equal to 100 grams.

[0079] In a specific embodiment, as Figure 1 shown, the weight detection devices 6 are arranged in one-to-one correspondence with the steaming and baking units 5, so the number of weight detection devices 6 is equal to the number of steaming and baking units 5. Each weight detection device 6 is used to detect the weight data of the food to be steamed and baked on the corresponding steaming and baking unit 5. In some embodiments, after the control module receives the weight data of the food to be steamed and baked corresponding to each of the 3 upper-layer steaming and baking units 5 and the weight data of the food to be steamed and baked corresponding to each of the 3 lower-layer steaming and baking units 5 detected by the steaming oven before steaming and baking, it can determine the average value of the sum of the weight data of the food to be steamed and baked corresponding to each of the 6 steaming and baking units 5, so as to determine the heating duration of the steaming and baking part 8 at the top inside the steaming oven housing 1 based on the determined average value, and then realize reasonable regulation of the heating duration of the steaming oven, so as to facilitate automatic control of the heating duration.

[0080] In practical applications, the corresponding relationship between the weight data and the heating duration can be set in the control module. Then, after determining the weight data, the corresponding heating duration can be directly determined. It should be noted that the corresponding relationship between the weight data and the heating duration of meat foods is different from that of vegetable foods. That is, for meat foods with equal weight values, the heating duration is longer than that of vegetable foods, and the heating duration of meat foods is greater than that of vegetable foods.

[0081] In a specific embodiment, the control module is further configured to determine the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device corresponding to the target weight detection device based on a series of consecutive weight data transmitted by the target weight detection device at a preset interval duration. And when the ripening speed data meets the first preset ripening speed condition, the control module controls the moving mechanism 7 to move, so that the target steaming and roasting device moves to a layer close to the steaming and roasting part 8. The target weight detection device is the upper steaming and roasting device 3 or the lower steaming and roasting device 4.

[0082] In the embodiment of the present application, based on a series of consecutive weight data transmitted by the target weight detection device at a preset interval duration, the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device corresponding to the target weight detection device can be determined. And when the ripening speed data meets the first preset ripening speed condition, the moving mechanism is controlled to move, so that the target steaming and roasting device moves to a layer close to the steaming and roasting part, thereby accurately controlling the movement of the target steaming and roasting device to avoid the situation that the maturity of the food varies greatly due to uneven heating.

[0083] In a specific embodiment, the first preset ripening speed condition is that the ripening speed data is less than or equal to the first preset ripening speed threshold. Then, when the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device meets the first preset ripening speed condition, it indicates that the ripening speed of the food to be steamed and roasted on the target steaming and roasting device is relatively slow. Then, the moving mechanism 7 can be controlled to move, so that the target steaming and roasting device moves to a layer close to the steaming and roasting part 8, thereby accelerating the steaming and roasting speed of the food to be steamed and roasted on the target steaming and roasting device and avoiding the situation that the maturity of the food to be steamed and roasted on the target steaming and roasting device varies greatly from that of the food to be steamed and roasted on another steaming and roasting device, which helps to further improve the steaming and roasting accuracy of the steam oven.

[0084] It should be noted that the target steaming and baking device corresponds to any steaming and baking unit 5 on the upper steaming and baking device 3 or any steaming and baking unit 5 on the lower steaming and baking device 4, and the target weight detection device is the weight detection device corresponding to the steaming and baking unit 5. Among them, when the maturity speed data of the food to be steamed and baked on the target steaming and baking device meets the first preset maturity speed condition, all the steaming and baking units 5 on the layer where the steaming and baking unit 5 corresponding to the target steaming and baking device is located need to be moved to the layer close to the baking element 8, so as to facilitate unified control of the whole layer of steaming and baking units 5, which helps to improve the control efficiency and achieve precise steaming and baking control.

[0085] In a specific embodiment, when the maturity speed data meets the second preset maturity speed condition, the moving mechanism 7 is controlled to move so that the target steaming and baking device moves to a layer away from the baking element 8. Specifically, the second preset maturity speed condition is greater than or equal to the second preset maturity speed threshold, where the second preset maturity speed threshold is greater than the first preset maturity speed threshold. Furthermore, when the maturity speed data of the food to be steamed and baked on the target steaming and baking device meets the second preset maturity speed condition, it indicates that the maturity speed of the food to be steamed and baked on the target steaming and baking device is relatively fast. Then, the moving mechanism 7 can be controlled to move so that the target steaming and baking device moves to a layer away from the baking element 8, thereby slowing down the steaming and baking speed of the food to be steamed and baked on the target steaming and baking device, and avoiding the situation that the maturity of the food to be steamed and baked on the target steaming and baking device and the food to be steamed and baked on another layer of the steaming and baking device differ greatly, which helps to further improve the steaming and baking accuracy of the steam oven.

[0086] The embodiment of the present application also provides a control method for a steam oven, where the steam oven includes all the technical features of the above-mentioned steam oven. Specifically, as Figure 4 shown, it is a schematic flowchart of a control method for a steam oven provided by an embodiment of the present application. Then, the above control method includes:

[0087] S101: Obtain the first maturity data of the food to be steamed and baked on the upper steaming and baking device 3 in the steam oven detected by the maturity detection device 2 in the steam oven, and the second maturity data of the food to be steamed and baked on the lower steaming and baking device 4 in the steam oven. Among them, the positions of the upper steaming and baking device 3 and the lower steaming and baking device 4 can be moved by the movement of the moving mechanism 7 in the steam oven;

[0088] S102: Control the moving mechanism 7 to move according to the first maturity data and the second maturity data.

[0089] Specifically, the first maturity data may be the color data of the surface of the food to be steamed and roasted on the upper steaming and roasting device 3 detected, and the second maturity data may be the color data of the surface of the food to be steamed and roasted on the lower steaming and roasting device 4 detected. It can be understood that the maturity detection device 2 can respectively detect the color data of the surface of the food to be steamed and roasted on the upper steaming and roasting device 3 and the lower steaming and roasting device 4, and then determine the position data of the movement of the upper steaming and roasting device 3 and the lower steaming and roasting device 4 driven by the moving mechanism 7 according to the color data of the surface of the food to be steamed and roasted on the corresponding layer.

[0090] In some embodiments, the maturity detection device 2 includes a first maturity detection unit 21 and a second maturity detection unit 22. Among them, the first maturity detection unit 21 is used to detect the first maturity data of the food to be steamed and roasted on the upper steaming and roasting device 3, that is, the color data of the surface of the food to be steamed and roasted on the upper steaming and roasting device 3, and the second maturity detection unit 22 is used to detect the second maturity data of the food to be steamed and roasted on the lower steaming and roasting device 4, that is, the color data of the surface of the food to be steamed and roasted on the lower steaming and roasting device 4. Then, according to the first maturity data and the second maturity data, the moving mechanism 7 can be controlled to move to change the relative position between the upper steaming and roasting device 3 and the lower steaming and roasting device 4, so that the steaming and roasting device located at the lower layer is moved to the upper layer, and the food to be steamed and roasted on the steaming and roasting device moved to the upper layer is close to the roasting member 8, so as to facilitate the steaming and roasting of the food to be steamed and roasted with a lower maturity. Furthermore, it can be ensured that the color data of the surfaces of the food to be steamed and roasted on the upper and lower steaming and roasting devices also gradually tend to be consistent, that is, the food to be steamed and roasted on the upper and lower steaming and roasting devices can be matured synchronously, thereby avoiding the situation that the food on the top is burnt and the food on the bottom is not cooked due to uneven heating of the food on the two fixed baking trays, and improving the steaming and roasting accuracy.

[0091] In a specific embodiment, as Figure 5 shown, it is a schematic flowchart of a moving mechanism control method provided by an embodiment of the present application. Specifically, step S102 may include:

[0092] S1021: When the first maturity data is greater than the second maturity data, control the moving mechanism 7 to move so that the position of the upper steaming and roasting device 3 is interchanged with the position of the lower steaming and roasting device 4;

[0093] S1022: When the difference between the first maturity data and the second maturity data satisfies a preset difference condition, control the moving mechanism 7 to move so that the upper steaming and roasting device 3 and the lower steaming and roasting device 4 perform uniform circular movement.

[0094] Specifically, when the first maturity data is greater than the second maturity data, it indicates that the color of the surface of the food to be steamed and roasted on the upper steaming and roasting device 3 is darker than the color of the surface of the food to be steamed and roasted on the lower steaming and roasting device 4. That is, it is necessary to reduce the heating degree of the food to be steamed and roasted in the upper steaming and roasting device 3. Furthermore, the moving mechanism can be controlled to move so that the position of the upper steaming and roasting device 3 is interchanged with the position of the lower steaming and roasting device. Exemplarily, all 3 steaming and roasting units 5 in the upper steaming and roasting device 3 can be moved to the positions of the 3 steaming and roasting units 5 in the lower steaming and roasting device 4, and all 3 steaming and roasting units 5 in the lower steaming and roasting device 4 can be moved to the positions of the 3 steaming and roasting units 5 in the upper steaming and roasting device 3 and then fixed, so as to increase the heating degree of the food to be steamed and roasted on the 3 steaming and roasting units 5 in the lower steaming and roasting device 4, thereby ensuring that the color data of the surfaces of the food to be steamed and roasted on the upper and lower steaming and roasting devices gradually tend to be consistent, so as to achieve precise movement control.

[0095] In some embodiments, the preset difference condition is that the difference between the first maturity data and the second maturity data is less than or equal to a preset difference threshold. Furthermore, when the difference between the first maturity data and the second maturity data meets the preset difference condition, it indicates that the color data of the surfaces of the food to be steamed and roasted on the upper and lower steaming and roasting devices tend to be consistent, but the steaming and roasting time has not reached. Furthermore, the moving mechanism 7 can be controlled to move so that the upper steaming and roasting device 3 and the lower steaming and roasting device 4 move slowly and evenly in a cycle until the steaming and roasting ends, so as to achieve precise movement control.

[0096] In a specific embodiment, as Figure 6 shown, it is a schematic flowchart of the method for determining the heating duration provided by the embodiment of the present application. Specifically, the method further includes:

[0097] S103: Obtain the first weight data of the food to be steamed and roasted on the upper steaming and roasting device 3 detected by the weight detection device 6 corresponding to the upper steaming and roasting device 3 in the steam oven, and the second weight data of the food to be steamed and roasted on the lower steaming and roasting device 4 detected by the weight detection device 6 corresponding to the lower steaming and roasting device 4 in the steam oven;

[0098] S104: Control the heating duration of the roasting part 8 at the top inside the steam oven box body 1 in the steam oven according to the first weight data and the second weight data.

[0099] In the embodiments of the present application, the first weight data is the weight data of the food to be steamed and baked on the upper steaming and baking device 3 detected before steaming and baking. It can be understood that the first weight data is the weight data of the food to be steamed and baked corresponding to each of the multiple steaming and baking units 5 in the upper steaming and baking device 3. The second weight data is the weight data of the food to be steamed and baked on the lower steaming and baking device 4 detected before steaming and baking. It can be understood that the second weight data is the weight data of the food to be steamed and baked corresponding to each of the multiple steaming and baking units 5 in the lower steaming and baking device 4. In actual applications, the first weight data and the second weight data are equal, or the difference between the first weight data and the second weight data satisfies a preset difference condition, where the preset difference condition can be less than or equal to 100 grams.

[0100] Furthermore, the control device can control the heating duration of the steaming and baking part 8 at the top inside the steaming and baking oven housing 1 based on the received first weight data and second weight data, so as to accurately control the heating duration of the steaming and baking part 8 according to the weight data detected by the weight detection device 6, thereby improving the steaming and baking accuracy.

[0101] In a specific embodiment, the weight detection devices 6 are arranged in one-to-one correspondence with the steaming and baking units 5. Each weight detection device 6 is used to detect the weight data of the food to be steamed and baked on the corresponding steaming and baking unit 5. In some embodiments, after the control module receives the weight data of the food to be steamed and baked corresponding to each of the 3 upper steaming and baking units 5 and the weight data of the food to be steamed and baked corresponding to each of the 3 lower steaming and baking units 5 detected before steaming and baking, it can determine the average value of the sum of the weight data of the food to be steamed and baked corresponding to each of the 6 steaming and baking units 5, so as to determine the heating duration of the steaming and baking part 8 at the top inside the steaming and baking oven housing 1 based on the determined average value, and further realize reasonable regulation of the heating duration of the steaming and baking oven, so as to facilitate automatic control of the heating duration.

[0102] In actual applications, the corresponding relationship between the weight data and the heating duration can be set in the control module. Furthermore, after the weight data is determined, the corresponding heating duration can be directly determined. It should be noted that the corresponding relationship between the weight data of meat food and the heating duration is different from the corresponding relationship between the weight data of vegetable food and the heating duration.

[0103] In a specific embodiment, as Figure 7 shown, it is a schematic flowchart of another mobile mechanism control method provided by the embodiments of the present application. Specifically, the method further includes:

[0104] S105: Obtain a continuous plurality of weight data transmitted by the target weight detection device in the steaming and baking oven at preset intervals. The target weight detection device is the upper steaming and baking device 3 or the lower steaming and baking device 4;

[0105] S106: Determine the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device corresponding to the target weight detection device according to a series of consecutive weight data transmitted by the target weight detection device within a preset time interval;

[0106] S107: When the ripening speed data meets the first preset ripening speed condition, control the moving mechanism 7 to move so that the target steaming and roasting device moves to a layer closer to the steaming and roasting component 8.

[0107] In the embodiment of the present application, according to a series of consecutive weight data transmitted by the target weight detection device within a preset time interval, the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device corresponding to the target weight detection device can be determined. When the ripening speed data meets the first preset ripening speed condition, control the moving mechanism to move so that the target steaming and roasting device moves to a layer closer to the steaming and roasting component, thereby accurately controlling the movement of the target steaming and roasting device to avoid the situation where the maturity of the food varies greatly due to uneven heating.

[0108] In a specific embodiment, the first preset ripening speed condition is that the ripening speed data is less than or equal to the first preset ripening speed threshold. Therefore, when the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device meets the first preset ripening speed condition, it indicates that the ripening speed of the food to be steamed and roasted on the target steaming and roasting device is slow. Then, control the moving mechanism 7 to move so that the target steaming and roasting device moves to a layer closer to the steaming and roasting component 8, thereby accelerating the steaming and roasting speed of the food to be steamed and roasted on the target steaming and roasting device and avoiding the situation where the maturity difference between the food to be steamed and roasted on the target steaming and roasting device and the food to be steamed and roasted on another steaming and roasting device is large, which helps to further improve the steaming and roasting accuracy of the steam oven.

[0109] In a specific embodiment, the method further includes:

[0110] S108: When the ripening speed data meets the second preset ripening speed condition, control the moving mechanism 7 to move so that the target steaming and roasting device moves to a layer farther away from the steaming and roasting component 8.

[0111] Specifically, the second preset ripening speed condition is greater than or equal to the second preset ripening speed threshold, where the second preset ripening speed threshold is greater than the first preset ripening speed threshold. Further, when the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device meets the second preset ripening speed condition, it indicates that the ripening speed of the food to be steamed and roasted on the target steaming and roasting device is relatively fast. Then, the moving mechanism 7 can be controlled to move so that the target steaming and roasting device moves to a layer away from the steaming and roasting part 8, thereby slowing down the steaming and roasting speed of the food to be steamed and roasted on the target steaming and roasting device, and avoiding the situation where the ripeness of the food to be steamed and roasted on the target steaming and roasting device and the food to be steamed and roasted on another layer of the steaming and roasting device differ greatly, which helps to further improve the steaming and roasting accuracy of the steam oven.

[0112] It should be noted that the target steaming and roasting device corresponds to any steaming and roasting unit 5 on the upper steaming and roasting device 3 or any steaming and roasting unit 5 on the lower steaming and roasting device 4. The target weight detection device is a weight detection device corresponding to the steaming and roasting unit 5. When the ripening speed data of the food to be steamed and roasted on the target steaming and roasting device meets the second preset ripening speed condition, all the steaming and roasting units 5 on the layer where the steaming and roasting unit 5 corresponding to the target steaming and roasting device is located need to be moved to a layer away from the steaming and roasting part 8, so as to facilitate unified regulation of the entire layer of steaming and roasting units 5, which helps to improve the regulation efficiency and achieve precise steaming and roasting control.

[0113] As can be seen from the above technical solutions of the embodiments of the present application, the following technical effects are achieved:

[0114] In the present application, by providing upper and lower layers of steaming and roasting devices, and the upper and lower layers of steaming and roasting devices can be moved through the movement of the moving mechanism, as well as the ripeness detection device and the control device, so as to use the ripeness detection device to detect the first ripeness data of the food to be steamed and roasted on the upper steaming and roasting device and the second ripeness data of the food to be steamed and roasted on the lower steaming and roasting device, so that the control device controls the moving mechanism to move based on the first ripeness data and the second ripeness data transmitted by the ripeness detection device, so as to drive the upper and lower layers of steaming and roasting devices to move. Further, the situation where the food on the fixed two-layer baking trays is unevenly heated, resulting in the food on the top being burnt and the food on the bottom being undercooked, can be avoided, and the steaming and roasting accuracy can be improved.

[0115] The structure shown in this embodiment is only a part of the structure related to the solution of the present application, and does not constitute a limitation on the device to which the solution of the present application is applied. The specific device may include more or fewer components than those shown, or combine some components, or have a different arrangement of components.

Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
