[0043] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0044] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed or detachable connections, mechanical or electrical connections, direct or indirect connections through an intermediate medium, and internal communication between two elements or interaction between two elements. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0045] In the description of the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first feature being in direct contact with the second feature, or may include the first feature being in contact with the second feature through another feature between them instead of being in direct contact. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0046] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0047] like Figure 1-Figure 3 As shown, the present invention provides a panel flipping mechanism, comprising a drive assembly 1, a support member 2, an opening and closing rod 3, and a guide rod 4. The opening and closing rod 3 has a transmission portion and a mounting portion at either end, the transmission portion being rotatably connected to the output end of the drive assembly 1, and the mounting portion being used to mount the panel. The drive assembly 1 is capable of driving the transmission portion to move in a first direction. The guide rod 4 has a support portion and a guide portion at either end, the support portion being rotatably connected to the support member 2, and the guide portion being rotatably connected to the opening and closing rod 3. When the drive assembly 1 drives the transmission portion to move, the opening and closing rod 3 drives the guide portion to rotate around the support portion, causing the mounting portion to move in the first direction and, driven by the guide portion, to move in a second direction perpendicular to the first direction.

[0048] In the present invention, the rotation of the guide rod 4 drives the opening and closing rod 3 to swing up and down during the horizontal extension and contraction process, thereby completing the opening and closing action of the panel. Compared with the limitation of the motion trajectory by the track slide groove, it is not easy to get stuck, occupies a small space, has a low preparation cost, has good structural stability, and has high driving accuracy, so that the opening and closing rod 3 can smoothly drive the panel to move in the horizontal and vertical directions. Moreover, due to the action of the guide rod 4, the opening and closing rod 3 can open and close more quickly than the track slide groove limitation, thereby being able to drive the panel more efficiently.

[0049] Optionally, the drive assembly 1 includes a motor 11, a transmission system 12, a fixed base 13, and a slider 14. The slider 14 serves as an output terminal and is slidably mounted on the fixed base 13. The transmission unit is rotatably connected to the slider 14. The motor 11 can drive the slider 14 to slide in a first direction via the transmission system 12. The cooperation between the fixed base 13 and the slider 14 ensures smooth and stable movement of the transmission unit in the first direction.

[0050] Specifically, the transmission system 12 includes a vertical block 121, a connecting rod 122, a driving gear 123, a driven gear 124, and a transmission gear 125. The connecting rod 122 is rotatably mounted on the vertical block 121, the driving gear 123 is fixedly connected to the output shaft of the motor 11, the driven gear 124 is fixedly connected to the connecting rod 122 and meshes with the driving gear 123, and the transmission gear 125 is fixedly connected to the connecting rod 122 and meshes with the rack portion on the slider 14. Through the coordination of multiple gears, the output power of the motor 11 can be smoothly transmitted to the slider 14. In addition to the coordination of the three gears described above, it is also possible to have two gears coordinated, with the driven gear 124 directly meshing with the rack portion on the slider 14, or to have other structures in which multiple gears are coordinated.

[0051] More specifically, two fixing seats 13 are arranged side by side, each fixing seat 13 is provided with a slider 14, each slider 14 is connected to an opening and closing rod 3, the panel is fixedly installed on the mounting parts of the two opening and closing rods 3, and a transmission gear 125 is provided at both ends of the connecting rod 122. Each transmission gear 125 is engaged with a slider 14, and the motor 11 drives the two sliders 14 to slide synchronously through the connecting rod 122, so that the opening and closing of the panel is more stable.

[0052] In this embodiment, each support member 2 and guide rod 4 is provided with one, and the guide rod 4 is rotatably connected to a single opening and closing rod 3. Under the guidance of the single guide rod 4, the two opening and closing rods 3 are coordinated and synchronized by the panel connected to them, effectively saving space. In addition to the above configuration, it is also possible to provide two support members 2 and two guide rods 4, respectively, with each support member 2 being rotatably connected to a guide rod 4, and each guide rod 4 being rotatably connected to a single opening and closing rod 3. In this case, the movement of the two opening and closing rods 3 is more balanced and stable.

[0053] Optionally, the panel flipping mechanism of the present invention further includes a first limiter 5 and a second limiter 6, each of which is electrically connected to a control unit. When the slider 14 slides to trigger the first limiter 5, the opening and closing lever 3 drives the panel to an open position, and the control unit controls the motor 11 to stop. When the slider 14 slides to trigger the second limiter 6, the opening and closing lever 3 drives the panel to a closed position, and the control unit controls the motor 11 to stop. The first limiter 5 and the second limiter 6 work together to make the panel flipping mechanism drive the panel more accurately and reliably.

[0054] Specifically, when the slider 14 slides to trigger the first limiter 5, the first limiter 5 sends a first stop signal to the control unit. Upon receiving the first stop signal, the control unit controls the motor 11 to stop and, when the motor 11 is restarted, controls the motor 11 to reverse. When the slider 14 slides to trigger the second limiter 6, the second limiter 6 sends a second stop signal to the control unit. Upon receiving the second stop signal, the control unit controls the motor 11 to stop and, when the motor 11 is restarted, controls the motor 11 to rotate forward. The control unit timely adjusts the forward or reverse rotation of the motor 11 according to the states of the first limiter 5 and the second limiter 6, effectively preventing damage to the panel flipping mechanism caused by overdriving of the motor 11.

[0055] More specifically, the first limit device 5 and the second limit device 6 are both limit switches, which are conventional settings in this field. Their structure and working principle are not repeated here. When the slider 14 touches the push rod of the limit switch, it can be triggered.

[0056] In this embodiment, the opening and closing lever 3 is plate-shaped and comprises a first plate 31 and a second plate 32 connected to each other. Reinforced flanges 33 are provided on both sides of the width of the second plate 32. The free end of the first plate 31 serves as a transmission portion, and the free end of the second plate 32 serves as a mounting portion. The guide rod 4 is connected to the second plate 32. The plate-shaped configuration of the opening and closing lever 3 effectively reduces occupied space. Furthermore, the provision of the reinforced flanges 33 provides a more stable and reliable support for the panel provided by the opening and closing lever 3.

[0057] The present invention also provides a steamer comprising the above-mentioned panel turning mechanism.

[0058] During the cooking process, the steamer requires a large amount of water vapor, so a large-capacity water box is required to provide water vapor for the normal operation of the steamer. In the steamer of the present invention, the water box is arranged on the water box bracket on the rear side of the panel. After the panel is raised to expose the water box, the water box is manually removed from the water box bracket to add water. After the water adding work is completed, the water box is manually put back into the water box bracket. The panel flipping mechanism in this application can lift the panel and extend the water box in an integrated manner. The user only needs to take and place the water box from the water box bracket, which is simple and convenient to operate.

[0059] Specifically, the control unit of the panel flip mechanism is a computer board inside the steamer, which can control the opening and closing of the panel according to the operation buttons or instructions of the control panel on the steamer. The control principle of the computer board working in conjunction with the first limit device 5 and the second limit device 6 is a conventional setting in the field and will not be repeated here.

[0060] In addition to the above-mentioned steamer, the panel flip mechanism of the present application can also be applied to other kitchen appliances, which will not be described in detail here.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
