[0002] Cooking devices are generally provided with control panels to facilitate user control of the devices, such as ovens and steamers. The control panel is generally fixed on the cooking device, and some cooking devices such as ovens and steamers are embedded in the kitchen cabinets. However, due to the closed design, the water tank and corresponding water accessories behind the control panel cannot be observed. If the control panel can be flipped open and laid flat, the water tank can be observed from the front of the product and can be taken out or placed, so that operations such as adding water to the water tank, emptying the water tank, cleaning the water tank, and even replacing the water tank can be achieved. When the control panel is closed and restored to the vertical state, the user can perform various cooking settings and operations on the control panel, and hide the control panel to reduce the volume.

DETAILED DESCRIPTION
[0038] The technical scheme in this embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in this embodiment of the present invention. Obviously, the described embodiment is one embodiment of the present invention, not all embodiments of the present invention. Based on this embodiment of the present invention, all other embodiments of the present invention obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0039] Embodiment 1
[0040] Please refer to Figures 1 to 16 , this embodiment provides a flipping mechanism for a control panel.
[0041] like Figure 1 As shown, the control panel 11 is mounted on the frame 12. In this embodiment, the control panel 11 is mounted on the upper end of the frame 12, so that the water tank can be observed from the front of the product and can be taken out or placed, so as to realize operations such as adding water to the water tank, emptying the water tank, cleaning the water tank, and even replacing the water tank. In other embodiments, the control panel 11 can also be mounted on the lower end of the frame 12, so that the components installed inside the control panel 11, such as the filter, can be taken out for cleaning.
[0042] like Figure 1 As shown, the control panel 11 is connected to the frame 12 via a rotating shaft 14, and the control panel 11 is flipped through the rotating shaft 14 to achieve a hinge connection; in this embodiment, the rotating shaft 14 is installed at the lower part of the control panel 11 to achieve the control panel 11 flipping forward.
[0043] like Figure 1 As shown, an upper plate 13 is installed on one side of the control panel 11, and the upper plate 13 is used to place and install a driving device to drive the control panel 11 to flip forward.
[0044] Specifically, a first rocker arm 61 is installed on one side of the upper plate 13, and a second rocker arm 62 is installed on the other side. The structures of the first rocker arm 61 and the second rocker arm 62 are the same and are designed symmetrically to each other. In other embodiments, more rocker arms can be provided to enable more connections with the control panel 11 and to ensure that the control panel 11 is evenly stressed.
[0045] Furthermore, the front ends of the first rocker arm 61 and the second rocker arm 62 pass through the frame 12 and are connected to the control panel 11, so that the control panel 11 is respectively connected to the two control components, so that the forces are symmetrical and the control panel 11 is evenly stressed during the flipping process.
[0046] Furthermore, a first sliding frame 21 is installed at the rear end of the first rocker arm 61, and correspondingly, a second sliding frame 22 is installed at the rear end of the second rocker arm 62. The first sliding frame 21 slides linearly along the first slide rail 91, and the second sliding frame 22 slides linearly along the second slide rail 92. The first slide rail 91 and the second slide rail 92 are fixedly installed on the upper plate 13.
[0047] The first rocker arm 61 slides linearly along the first slide rail 91 through the first sliding frame 21, and the second rocker arm 62 slides linearly along the second slide rail 92 through the second sliding frame 22, so that the linear motion is smooth and continuous, thereby resulting in smooth and continuous flipping motion.
[0048] The first sliding frame 21 and the second sliding frame 22 are also synchronously connected through the synchronous transmission shaft 5; thereby, the first rocker arm 61 and the second rocker arm 62 have consistent movements, which in turn leads to consistent flipping movements, accurate and adjustable flipping angles, and a safe and reliable flipping process.
[0049] When the present invention is working, the synchronous transmission shaft 5 is driven by an external force, so that the first sliding frame 21 slides linearly along the first slide rail 91, and the second sliding frame 22 slides linearly along the second slide rail 92; the front ends of the first rocker arm 61 and the second rocker arm 62 extend to the front of the frame 12, driving the control panel 11 to flip around the rotating shaft 14; the control panel 11 flips a certain angle, and the flipping angle can be set, generally between 0° and 180°, preferably 90°, so that the control panel 11 and the frame 12 are perpendicular to each other.
[0050] Furthermore, the first sliding frame 21 and the second sliding frame 22 can directly slide linearly under the drive of the cylinder.
[0051] like Figure 3 As shown, the first rocker arm 61 and the first sliding frame 21 are hingedly connected via a first connecting shaft 93, and the first connecting shaft 93 connects the first rocker arm 61 and the first sliding frame 21; similarly, the second rocker arm 62 and the second sliding frame 22 are hingedly connected via a second connecting shaft 94; in order to reduce the friction during the sliding process and extend the service life; support balls are arranged between the first sliding frame 21 and the first slide rail 91, and between the second sliding frame 22 and the second slide rail 92; rolling friction is used instead of sliding friction.
[0052] like Figure 4As shown, a first synchronous wheel assembly 41 is installed on one side of the first slide rail 91, and a second synchronous wheel assembly 42 is installed on one side of the second slide rail 92. The first synchronous wheel assembly 41 is transmission connected to the first rocker arm 61, and the second synchronous wheel assembly 42 is transmission connected to the second rocker arm 62. The first synchronous wheel assembly 41 and the second synchronous wheel assembly 42 are synchronously connected through a synchronous transmission shaft 5, and the synchronous transmission shaft 5 is transmission connected to the drive motor 7.
[0053] The movement process in this embodiment is as follows: the driving motor 7 drives the synchronous transmission shaft 5 to rotate, and drives the first rocker arm 61 and the second rocker arm 62 to move linearly through the first synchronous wheel assembly 41 and the second synchronous wheel assembly 42, thereby driving the control panel 11 to flip around the rotating shaft 14.
[0054] like Figure 4 As shown, the structures of the first synchronous wheel assembly 41 and the second synchronous wheel assembly 42 are basically the same and can be understood by comparison.
[0055] Specifically, Figure 7 As shown, the first synchronous wheel assembly 41 includes a first synchronous wheel bracket 411 connected to the upper plate 13, first synchronous wheels 412 installed at both ends of the first synchronous wheel bracket 411, a first synchronous belt 413 sleeved on the first synchronous wheel 412, and a first push block 414 installed on the first synchronous belt 413, and the end of the first push block 414 is connected to the first sliding frame 21. Further, the first synchronous wheel bracket 411 is U-shaped, and the two first synchronous wheels 412 are respectively placed at the two ends of the U-shaped first synchronous wheel bracket 411. The first push block 414 is fixed at the lower part of the first synchronous belt 413, and the end is connected to the first sliding frame 21, so as to convert the rotational motion of the first synchronous wheel 412 into the linear motion of the first synchronous belt 413, and push the first sliding frame 21 to reciprocate linearly.
[0056] Similarly, if Figure 8 As shown, the second synchronous wheel assembly 42 includes a second synchronous wheel bracket 421 connected to the upper plate 13, a second synchronous wheel 422 installed at both ends of the second synchronous wheel bracket 421, a second synchronous belt 423 sleeved on the second synchronous wheel 422 and a second pushing block 424 installed on the second synchronous belt 423, and the end of the second pushing block 424 is connected to the second sliding frame 22.
[0057] In order to realize the synchronous rotation of the first synchronous wheel 412 and the second synchronous wheel 422, as shown in FIG. Fig.11As shown, the first synchronous wheel 412 is installed at one end of the synchronous transmission shaft 5, and the second synchronous wheel 422 is installed at the other end of the synchronous transmission shaft 5, so as to realize the synchronous transmission connection; further, in this embodiment, the synchronous transmission shaft 5 serves as a part of the transmission, and the synchronous transmission shaft 5 drives the first synchronous wheel 412 and the second synchronous wheel 422 to rotate synchronously.
[0058] like Figure 6 As shown, a reduction gear set 71 is installed at the end of the driving motor 7, and the reduction gear set 71 is meshed and connected with the driving gear 51 on the synchronous transmission shaft 5; a control PCB board 72 is also installed on the upper plate 13, and the control PCB board 72 is electrically connected to the driving motor 7 to control the output of the driving motor 7; further, the control PCB board 72 is also provided with a current sensing element for monitoring the current of the driving motor 7, so as to monitor the rotation of the driving motor 7 in real time, and also prevent the control panel 11 from pinching hands or foreign objects.
[0059] In this embodiment, first, the control PCB board 72 controls the drive motor 7 to rotate, and drives the rotation of the synchronous transmission shaft 5 after being decelerated by the reduction gear group 71; secondly, the synchronous transmission shaft 5 drives the first synchronous wheel 412 and the second synchronous wheel 422 to rotate synchronously; the first synchronous wheel 412 and the second synchronous wheel 422 respectively drive the first synchronous belt 413 and the second synchronous wheel 422 to move linearly; thirdly, the first pushing block 414 on the first synchronous belt 413 pushes the first sliding frame 21 to move linearly, and the second pushing block 424 on the second synchronous wheel 422 pushes the second sliding frame 22 to move linearly; finally, the first sliding frame 21 and the second sliding frame 22 slide linearly along the first slide rail 91 and the second slide rail 92 respectively, so that the first rocker arm 61 and the second rocker arm 62 extend to the front of the frame 12, driving the control panel 11 to flip around the rotating shaft 14.
[0060] like Fig.12 As shown, the control panel 11 includes a first locking hook 15 installed on one side and hingedly connected to the first rocker arm 61, and a second locking hook 16 installed on the other side and hingedly connected to the second rocker arm 62. The first rocker arm 61 controls or drives the control panel 11 through the first locking hook 15, and at the same time, the second rocker arm 62 controls or drives the control panel 11 through the second locking hook 16.
[0061] Furthermore, a first control button 17 is provided on the front side of the control panel 11, and a second control button 18 is provided on the rear side. The first control button 17 controls the control panel 11 to open, and the second control button 18 controls the control panel 11 to close. The first control button 17 and the second control button 18 can be physical buttons, touch buttons, or virtual buttons.
[0062] like Fig.12 As shown, in this embodiment, the rotating shaft 14 is provided with two, namely a first rotating shaft 141 provided at one side of the control panel 11 and a second rotating shaft 142 provided at the other side of the control panel 11; correspondingly, as shown in Figure 4 As shown, a first panel fixing frame 121 is installed on one side of the frame 12, and a second panel fixing frame 122 is installed on the other side; the first rotating shaft 141 is inserted into the first panel fixing frame 121, and the second rotating shaft 142 is inserted into the second panel fixing frame 122, so as to realize the flipping of the control panel 11 around the lower rotating shaft 14.
[0063] Furthermore, the first panel fixing frame 121 and the second panel fixing frame 122 are both L-shaped. The first panel fixing frame 121 and the second panel fixing frame 122 are fixedly mounted on the rear of the frame 12 , and their ends pass through the frame 12 and are plugged into the rotating shaft 14 , thereby being connected to the control panel 11 .
[0064] like Fig. 9 and Fig.10 As shown, the first rocker arm 61 is provided with a first cover plate 63 on the outside, and the second rocker arm 62 is provided with a second cover plate 64 on the outside. The cover plates are used to protect the internal rocker arm, so that the movement is smoother and the service life is extended.
[0065] Furthermore, a first infrared sensor 65 is installed on the first cover plate 63, and a second infrared sensor 66 is installed on the second cover plate 64. When the first rocker arm 61 and the second rocker arm 62 extend forward of the frame 12, the first infrared sensor 65 and the second infrared sensor 66 start to work and emit and receive signals from each other.
[0066] A first implementation method of the first infrared sensor 65 and the second infrared sensor 66: when the control panel 11 is flipped open, the first infrared sensor 65 and the second infrared sensor 66 start working and continue to shoot and receive each other; when something like a human hand or other obstacles block the first infrared sensor 65 and the second infrared sensor 66, making it impossible to sense the infrared signal, they immediately identify it and send a command signal through the control PCB board 72 to stop the rotation of the drive motor 7, and the first infrared sensor 65 and the second infrared sensor 66 continue to work, thereby realizing the first safety protection function of the control panel 11 to prevent pinching of hands or foreign objects.
[0067] In this embodiment, in order to make the first infrared sensor 65 and the second infrared sensor 66 easier to control, a second implementation method of the first infrared sensor 65 and the second infrared sensor 66 is: a first micro switch 68 is provided to start and shut it down, so that it is started when the control panel 11 is opened, and shut down when the control panel 11 is closed.
[0068] Specifically, a first micro switch 68 is installed on one side of the first cover plate 63, and the first micro switch 68 is fixedly installed on the rear side of the frame 12. The first micro switch 68 is electrically connected to the first infrared sensor 65 and the second infrared sensor 66 respectively; further, in other embodiments, the first micro switch 68 can also be electrically connected to the first infrared sensor 65 and the second infrared sensor 66 through the control PCB board 72.
[0069] Furthermore, in order to control the first microswitch 68, a first boss 67 is provided on the side of the first cover plate 63 corresponding to the first microswitch 68, and the first boss 67 contacts the first microswitch 68, pressing the first microswitch 68, and the first infrared sensor 65 and the second infrared sensor 66 are closed; the first boss 67 moves away from the first microswitch 68, releasing the first microswitch 68, and the first infrared sensor 65 and the second infrared sensor 66 are turned on and start working.
[0070] In actual application, when the first rocker arm 61 and the second rocker arm 62 extend forward to the front of the frame 12, the first boss 67 separates from the first micro switch 68, the first micro switch 68 is released, and the first infrared sensor 65 and the second infrared sensor 66 are activated.
[0071] In this embodiment, the control PCB board 72 is also equipped with a current sensing element for detecting the current of the driving motor 7, thereby realizing the second safety protection function of the control panel 11 to prevent fingers from being pinched or foreign objects from being pinched.
[0072] Specifically, the current sensing element is electrically connected to the drive motor 7 to detect the current of the drive motor 7 in real time. When a hand or other obstacle is accidentally clamped when the control panel 11 is flipped and retracted; when the drive motor 7 encounters resistance and the rotation is blocked (such as when a stall test occurs), the drive motor 7 will produce an increase in current. At this time, the current sensing element in the control PCB board 72 detects the increase in the current of the drive motor 7, and sends a stop command to the drive motor 7; thereby realizing the second safety protection function of the control panel 11 to prevent fingers or foreign objects from being clamped.
[0073] In this embodiment, the control panel 11 is also provided with a hard limiter; Fig.15 As shown, the first cover plate 63 and the second cover plate 64 are both provided with a limiting rod 69. When the first rocker arm 61 and the second rocker arm 62 extend forward of the frame 12, the limiting rod 69 contacts the frame 12 to perform hard limiting.
[0074] In this embodiment, a control panel 11 is further provided for retracting a hard limit; a stop frame 60 is provided at the rear end of the first sliding frame 21 and the second sliding frame 22. When the first rocker arm 61 and the second rocker arm 62 are retracted to the rear of the frame 12, the first sliding frame 21 and the second sliding frame 22 contact the stop frame 60 for hard limiting.
[0075] In this embodiment, the control panel 11 is also provided with a soft limiter; Figure 8 As shown, a second micro switch 99 is installed at one end of the second synchronous wheel bracket 421, and a third micro switch 98 is installed at the other end; the second micro switch 99 and the third micro switch 98 are both electrically connected to the drive motor 7; in the actual connection process, the second micro switch 99 and the third micro switch 98 are electrically connected to the drive motor 7 through the control PCB board 72; when the first rocker arm 61 and the second rocker arm 62 extend forward of the frame 12, the second connecting shaft 94 contacts the second micro switch 99 to control the drive motor 7 to stop rotating; and the extension soft limit is performed.
[0076] In this embodiment, a control panel 11 is also provided for retracting the soft limit; when the first rocker arm 61 and the second rocker arm 62 are retracted to the rear of the frame 12, the second connecting shaft 94 contacts the third micro switch 98, controlling the drive motor 7 to stop rotating and retract the soft limit.
[0077] Furthermore, in this embodiment, the flip angle of the control panel 11 can be adjusted by adjusting the positions of the second microswitch 99 and the third microswitch 98, which is generally set at 90°, but can be increased or decreased on the above angle, so as to be suitable for kitchen appliances of various capacities and has a wide range of applications.
[0078] Furthermore, by adjusting the installation positions of the first infrared sensor 65 and the second infrared sensor 66, the travel range of the infrared sensor to start the protection and close and flip the structure can be achieved, which is flexible, convenient, reliable and safe to use.
[0079] In addition, by adjusting the reaction value of the current sensing data size of the current sensing element, it is possible to adjust the resistance of the control panel 11 when a human hand or obstacle blocks the control panel 11 during the flipping movement, and then issue a rotation stop command for the drive motor 7. According to the actual use requirements of different kitchen appliances, the actual use requirements can be met by replacing the drive motor 7 models with different speeds and torques.
[0080] The control panel 11 flips over and closes the function:
[0081] like Fig.13 and Fig.14As shown, the control PCB board 72 controls the drive motor 7 to rotate counterclockwise, and after the reduction of the reduction gear set 71, drives the synchronous transmission shaft 5 to rotate counterclockwise; the synchronous transmission shaft 5 drives the first synchronous wheel 412 and the second synchronous wheel 422 to rotate counterclockwise;
[0082] The first synchronous wheel 412 and the second synchronous wheel 422 respectively drive the first synchronous belt 413 and the second synchronous wheel 422 to move linearly backward; the first pushing block 414 on the first synchronous belt 413 pushes the first sliding frame 21 to move linearly backward; the second pushing block 424 on the second synchronous wheel 422 pushes the second sliding frame 22 to move linearly backward;
[0083] The first sliding frame 21 and the second sliding frame 22 slide linearly backward along the first slide rail 91 and the second slide rail 92 respectively, so that the first rocker arm 61 and the second rocker arm 62 retract to the rear of the frame 12, and drive the control panel 11 to flip and close around the rotating shaft 14.
[0084] When the first rocker arm 61 and the second rocker arm 62 are retracted to the rear of the frame 12, the second connecting shaft 94 contacts the third micro switch 98, and the driving motor 7 is controlled to stop rotating, and the flipping and closing action of the control panel 11 stops.
[0085] Similarly, if Fig.15 and Fig.16 As shown, the flip-open function of the control panel 11 is exactly opposite to the closing function, which will not be described in detail here.
