DETAILED DESCRIPTION

[0039] 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.

[0040] Embodiment 1

[0041] Please refer to Figures 1 to 17 , this embodiment provides a flip structure of a control panel.

[0042] 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.

[0043] like Figure 1As 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.

[0044] 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.

[0045] Specifically, a first connecting rod 61 is installed on one side of the upper plate 13, and a second connecting rod 62 is installed on the other side. The structures of the first connecting rod 61 and the second connecting rod 62 are the same and are designed to be symmetrical with each other. Furthermore, the front ends of the first connecting rod 61 and the second connecting rod 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 parts, thereby achieving mutual symmetry of the forces, and the control panel 11 is evenly stressed during the flipping process.

[0046] Furthermore, the rear end of the first connecting rod 61 is equipped with a first sliding shaft 21, and correspondingly, the rear end of the second connecting rod 62 is equipped with a second sliding shaft 22. The first sliding shaft 21 is clamped in the first groove 91, and the second sliding shaft 22 is clamped in the second groove 92; the first connecting rod 61 slides linearly along the first groove 91 through the first sliding shaft 21, and the second connecting rod 62 slides linearly along the second groove 92 through the second sliding shaft 22, so that the linear motion is smooth and continuous, which in turn leads to smooth and continuous flipping motion.

[0047] Furthermore, the first sliding shaft 21 and the second sliding shaft 22 are also synchronously connected through the synchronous transmission shaft 5; thereby, the first connecting rod 61 and the second connecting rod 62 have consistent movements, which leads to consistent flipping movements, accurate and adjustable flipping angles, and a safe and reliable flipping process.

[0048] Driven by external force, the first sliding shaft 21 and the second sliding shaft 22 slide linearly along the first groove 91 and the second groove 92 respectively, so that the first connecting rod 61 and the second connecting rod 62 extend to the front of the frame 12, driving the control panel 11 to flip around the rotating shaft 14.

[0049] Furthermore, the first sliding shaft 21 and the second sliding shaft 22 can directly slide linearly under the drive of the cylinder; they can also be driven by a drive motor 7, and the rotational motion is converted into the linear motion of the first sliding shaft 21 and the second sliding shaft 22 by the cooperation of gears and racks, and synchronously transmitted through the synchronous transmission shaft 5.

[0050] like Figure 3As shown, a first linear track housing 93 is installed on one side of the upper plate 13, and a second linear track housing 94 is installed on the other side; a first groove 91 is provided inside the first linear track housing 93, and a second groove 92 is provided inside the second linear track housing 94; a first bearing 95 is sleeved on the outside of the first sliding shaft 21, and the first linear track housing 93 clamps the first sliding shaft 21 and the first bearing 95 in the first groove 91 to achieve the encapsulation of the first sliding shaft 21 and the first bearing 95; similarly, a second bearing 96 is sleeved on the outside of the second sliding shaft 22, and the second linear track housing 94 clamps the second sliding shaft 22 and the second bearing 96 in the second groove 92 to achieve the encapsulation of the second sliding shaft 22 and the second bearing 96, thereby reducing the entry of external dust into the bearing, and the bearing is sleeved on the sliding shaft, which can reduce the friction during the sliding process, thereby reducing the flipping resistance of the control panel 11 and extending the service life.

[0051] The end of the first sliding shaft 21 extends out and is connected to the rear end of the first connecting rod 61, thereby limiting the first connecting rod 61 so that the first connecting rod 61 can have a stable motion state and output; similarly, the end of the second sliding shaft 22 extends out and is connected to the rear end of the second connecting rod 62, thereby limiting the second connecting rod 62 so that the second connecting rod 62 can have a stable motion state and output.

[0052] like Figure 4 As shown, a first synchronous wheel assembly 41 is installed on one side of the first linear track housing 93, and a second synchronous wheel assembly 42 is installed on one side of the second linear track housing 94. The first synchronous wheel assembly 41 is transmission connected to the first connecting rod 61, and the second synchronous wheel assembly 42 is transmission connected to the second connecting rod 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 connecting rod 61 and the second connecting rod 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 8As 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 one end of the first sliding shaft 21. Further, the first synchronous wheel bracket 411 is U-shaped, and the two first synchronous wheels 412 are respectively placed at both ends of the U-shaped first synchronous wheel bracket 411. The lower part of the first push block 414 is fixed to the first synchronous belt 413, and the end is connected to the first sliding shaft 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 shaft 21 to reciprocate linearly.

[0056] Similarly, if Fig. 9 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 an end of the second pushing block 424 is connected to one end of the second sliding shaft 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.12 As 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 7 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 rotation of the driving motor 7, and drives the rotation of the synchronous transmission shaft 5 after being decelerated by the reduction gear set 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 shaft 21 to move linearly, and the second pushing block 424 on the second synchronous wheel 422 pushes the second sliding shaft 22 to move linearly; finally, the first sliding shaft 21 and the second sliding shaft 22 slide linearly along the first groove 91 and the second groove 92 respectively, so that the first connecting rod 61 and the second connecting rod 62 extend to the front of the frame 12, driving the control panel 11 to flip around the rotating shaft 14.

[0060] like Fig.13 As shown, the control panel 11 includes a first locking hook 15 installed on one side and hingedly connected to the first connecting rod 61, and a second locking hook 16 installed on the other side and hingedly connected to the second connecting rod 62. The first connecting rod 61 controls or drives the control panel 11 through the first locking hook 15, and at the same time, the second connecting rod 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.13 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 and Fig.17 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.10 and Fig.11 As shown, the first connecting rod 61 is provided with a first cover plate 63 on the outside, and the second connecting rod 62 is provided with a second cover plate 64 on the outside. The cover plates are used to protect the internal connecting rods, 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 connecting rod 61 and the second connecting rod 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, the 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; 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, and 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.

[0068] 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.

[0069] In actual application, when the first connecting rod 61 and the second connecting rod 62 extend to the front of the frame 12, the first boss 67 is separated 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.

[0070] 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.

[0071] 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.

[0072] In this embodiment, the control panel 11 is also provided with a hard limiter. Fig.16 As shown, the first cover plate 63 and the second cover plate 64 are both provided with a limiting rod 69. When the first connecting rod 61 and the second connecting rod 62 extend forward of the frame 12, the limiting rod 69 contacts the frame 12 to perform hard limiting.

[0073] In this embodiment, the control panel 11 is also provided to retract the hard limit; Fig.15 As shown, when the first connecting rod 61 and the second connecting rod 62 are retracted to the rear of the frame 12, the limiting rod 69 on one side contacts the first synchronous wheel bracket 411, and the limiting rod 69 on the other side contacts the second synchronous wheel bracket 421, performing hard limiting.

[0074] In this embodiment, the control panel 11 is also provided with a soft limiter; Fig. 9 As shown, a second microswitch 99 is installed at one end of the second synchronous wheel bracket 421, and a third microswitch 98 is installed at the other end; the second microswitch 99 and the third microswitch 98 are both electrically connected to the drive motor 7; in the actual connection process, the second microswitch 99 and the third microswitch 98 are electrically connected to the drive motor 7 through the control PCB board 72; a second boss 425 is provided at the lower part of the second pushing block 424; when the first connecting rod 61 and the second connecting rod 62 extend to the front of the frame 12, the second boss 425 contacts the second microswitch 99, controls the drive motor 7 to stop rotating, and performs soft limit extension.

[0075] In this embodiment, a control panel 11 is also provided to retract the soft limit; when the first connecting rod 61 and the second connecting rod 62 are retracted to the rear of the frame 12, the second boss 425 contacts the third micro switch 98, controlling the drive motor 7 to stop rotating and retract the soft limit.

[0076] Furthermore, in this embodiment, the flip angle of the control panel 11 can be adjusted by adjusting the positions of the second micro switch 99 and the third micro switch 98, which is generally set at 90°, but can be increased or decreased on the above angle, so as to be applicable to various kitchen appliances with different capacities and a wide range of applications. In addition, it is also necessary to match and adjust with the limit rod 69, the first synchronous wheel bracket 411 and the second synchronous wheel bracket 421.

[0077] 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.

[0078] 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.

[0079] The control panel 11 flips over and closes the function:

[0080] like Fig.14 and Fig.15 As 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;

[0081] 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 shaft 21 to move linearly backward; the second pushing block 424 on the second synchronous wheel 422 pushes the second sliding shaft 22 to move linearly backward;

[0082] The first sliding shaft 21 and the second sliding shaft 22 slide linearly backward along the first groove 91 and the second groove 92 respectively, so that the first connecting rod 61 and the second connecting rod 62 retract to the rear of the frame 12, driving the control panel 11 to flip and close around the rotating shaft 14.

[0083] When the first connecting rod 61 and the second connecting rod 62 are retracted to the rear of the frame 12, the second boss 425 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.

[0084] Similarly, if Fig.16 and Fig.17 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.
