[0031] To more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of the present invention. Those skilled in the art can apply the present invention to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0032] As used herein and in the claims, unless the context clearly indicates otherwise, the terms "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0033] Although the present invention makes various references to certain modules in the system according to an embodiment of the present invention, any number of different modules can be used and run on a computing device and / or processor. The modules are only illustrative, and different aspects of the system and method can use different modules.

[0034] It should be understood that when a unit or module is described as being "connected" or "coupled" to other units, modules, or blocks, it can refer to being directly connected or coupled, or communicating with other units, modules, or blocks, or there can be intervening units, modules, or blocks, unless the context clearly indicates otherwise. As used herein, the term "and / or" may include any and all combinations of one or more of the associated listed items.

[0035] The embodiment of the present application proposes a steam oven, such as Figure 1-2 As shown, the steam oven includes an inner pot 1, a reversible heating tube 2 arranged in the inner pot 1, a driving mechanism 3 for driving the heating tube 2 to flip, a status detection unit 4 for detecting the status of the heating tube 2, and a control unit 6 electrically connected to the driving mechanism 3 and the status detection unit 4.

[0036] Through holes are provided on both sides of the lower rear of the inner tank 1, and high-temperature resistant silicone pads are installed on the through holes. The two ends of the heating tube 2 pass through the middle of the silicone pads respectively to play a limiting and sealing role.

[0037] A bearing structure is installed on one side of the inner container 1. One end of the heating tube 2 has an interference fit with the inner ring of the bearing and is secured in place with a stopper 201. The outer ring of the bearing secures the bearing to the inner container 1 with four nuts, while also tightening the silicone gasket for a better seal. The outer ring of the bearing is equipped with a first stopper 202 and a second stopper 203, which limit the rotational position of the heating tube 2.

[0038] like Figure 3 As shown, the state detection unit 4 includes a first microswitch and a second microswitch. The first microswitch is provided at the first limiting structure 202, and the second microswitch is provided at the second limiting structure 203. When the heating tube 2 is in the first initial state, the first microswitch outputs a high-level signal; when the heating tube 2 is in the second initial state, the second microswitch outputs a high-level signal.

[0039] A gear transmission structure is provided on the other side of the inner tank 1, and the other end of the heating tube 2 is fixed to the gear. Two circles of raised ribs are designed on one end face of the gear. While pressing the silicone pad, the contact area with the silicone pad is reduced to reduce friction. When the gear rotates to drive the heating tube 2 to flip, the silicone pad will not rotate, thereby increasing the life of the silicone pad.

[0040] like Figure 4 As shown, the drive mechanism 3 includes a drive circuit and a motor. The motor is fixed to the inner container 1 via a bracket. A gear is fixed to the top of the motor shaft and meshes with the gear of the heating tube 2. By controlling the forward and reverse rotation of the motor, the heating tube 2 can be rotated forward and reverse, thereby realizing the flipping function of the heating tube 2.

[0041] The heating tube 2 can be positioned horizontally or vertically within the inner container 1. This position is determined by the oven's operating mode. For example, when the oven is in lower heating tube mode, the heating tube 2 is horizontal; when the oven is in cleaning mode or back-of-tube mode, the heating tube 2 is vertical.

[0042] The control unit receives a user instruction and selects a working mode to be executed currently.

[0043] The control unit 6 determines the target state of the heating tube 2 in response to the working mode of the steam oven; uses the state detection unit 4 to obtain the initial state of the heating tube 2, and if the initial state is different from the target state, controls the driving mechanism 3 to drive the heating tube 2 to flip to the target state.

[0044] The control unit 6 obtains the initial state of the heating tube 2 according to the initial level signals output by the first micro switch and the second micro switch.

[0045] If the initial level signals output by the first microswitch and the second microswitch are different from the target level signals, the control unit controls the driving mechanism 3 to drive the heating tube 2 to flip until the first microswitch and the second microswitch output the target level signals.

[0046] This embodiment is suitable for different heating methods by arranging a reversible heating tube 2 in the inner pot 1, and is conducive to cleaning and maintenance of the steam oven.

[0047] In some embodiments, as Figure 2 As shown, the steam oven further includes a current detection unit 5 for detecting the driving current output by the driving mechanism 3 .

[0048] The control unit 6 obtains the current detected by the current detection unit 5 and determines whether the current is greater than a current threshold; if so, the control unit 6 controls the driving mechanism 3 to stop working.

[0049] By determining whether the current is greater than the current threshold, it can be determined whether the motor is in a normal working state or in a state of motor deadlock. When the motor is locked, the motor is controlled to stop working and fault information is output at the same time.

[0050] like Figure 5 As shown, an embodiment of the present application provides a control method for a steam oven, which is applied to the above-mentioned steam oven and specifically includes the following steps:

[0051] S502: Determining a target state of the heating tube in response to an operating mode of the steam oven;

[0052] The operation modes of the steam oven include, for example, a lower heating tube mode, a cleaning mode, or a back tube mode.

[0053] The target state can be horizontal or vertical.

[0054] S504: Utilizing the state detection unit to obtain an initial state of the heating tube, and if the initial state is different from the target state, controlling the driving mechanism to drive the heating tube to flip to the target state.

[0055] The initial state can be horizontal or vertical.

[0056] Based on the above steps S502-S506, this embodiment determines the target state of the heating tube in response to the operating mode of the steam oven; uses the state detection unit to obtain the initial state of the heating tube; if the initial state is different from the target state, controls the driving mechanism to drive the heating tube to flip to the target state, thereby realizing automatic flipping control of the heating tube.

[0057] In some embodiments, the state detection unit includes a first microswitch and a second microswitch. When the heating tube is in a first initial state, the first microswitch outputs a high-level signal; when the heating tube is in a second initial state, the second microswitch outputs a high-level signal. Based on this, the initial state of the heating tube can be determined based on the initial level signals output by the first and second microswitch.

[0058] In some embodiments, the target state of the heating tube corresponds to the target level signal output by the first microswitch and the second microswitch; if the initial level signal output by the first microswitch and the second microswitch is different from the target level signal, the driving mechanism is controlled to drive the heating tube to flip until the first microswitch and the second microswitch output the target level signal.

[0059] In some embodiments, when the heating tube is in a horizontal state, the first microswitch outputs a high-level signal and the second microswitch outputs a low-level signal; when the heating tube is in a vertical state, the first microswitch outputs a low-level signal and the second microswitch outputs a high-level signal.

[0060] In some embodiments, the method further includes: obtaining the current detected by the current detection unit, and determining whether the current is greater than a current threshold; if so, controlling the driving mechanism to stop working.

[0061] By determining whether the current is greater than the current threshold, it can be determined whether the motor is in a normal working state or in a state of motor deadlock. When the motor is locked, the motor is controlled to stop working and fault information is output at the same time.

[0062] In the first exemplary embodiment, the steam oven is in cleaning mode or back-of-house mode. If the first microswitch outputs a high-level signal of 1 and the second microswitch outputs a low-level signal of 0, the heating tube is in a horizontal position. The drive mechanism is then activated, causing the heating tube to begin rotating clockwise until the second microswitch outputs a low-level signal of 1 and the first microswitch outputs a high-level signal of 0, indicating that the heating tube has flipped into place. The heating tube is now in a vertical position, perpendicular to the bottom of the inner pot. Finally, the drive mechanism is deactivated.

[0063] In the first exemplary embodiment, the steam oven operates in the bottom heating tube mode. If the first microswitch outputs a high-level signal of 0 and the second microswitch outputs a low-level signal of 1, the heating tube is in a vertical position. The drive mechanism is then activated, causing the heating tube to begin rotating counterclockwise until the second microswitch outputs a low-level signal of 0 and the first microswitch outputs a high-level signal of 1, indicating that the heating tube has flipped over and is now horizontal. Finally, the drive mechanism is deactivated.
