[0030] <Example 1>

[0031] This embodiment proposes a household kitchen appliance, in particular a household appliance (such as an oven, an integrated stove, etc.) equipped with a display screen and operated and controlled by the display screen, which at least includes a body and a display screen flipping mechanism installed on the body, and the display screen flipping mechanism is a manual display screen flipping mechanism 1. Figure 1As shown, the manual flip mechanism 1 of the display screen includes a mounting frame 2, a flip frame 3, a display screen 4, a pushing member 5 and a locking assembly 6. The flip frame 3 is rotatably set on the mounting frame 2, and the display screen 4 is installed on the front side of the flip frame 3, and has a flip state and a closed state; the pushing member 5 is tilted, with one end mounted on the upper end of the mounting frame 2 and the other end mounted on the lower end of the flip frame 3, and is located on the rear side of the display screen 4, and is used to push the flip frame 3 to flip so that the display screen 4 is in a flip state.

[0032] like Figure 1 and Figure 2 As shown, the mounting frame 2 has a front frame 24 and a rear frame 23, the front side of the flip frame 3 is mounted on the front frame 24, and the display screen 4 is also located on the front frame 24. Figure 4 As shown, the lock assembly 6 comprises a lock head 61, a lock body 62, and a lock catch 63. The lock head 61 is fixed to the rear side of the flip frame 3, and the lock body 62 is fixed to the rear frame 23 of the mounting frame 2. The rear frame 23 has a through hole 231 through which the lock head 61 can extend and cooperate with the lock catch 63. The lock catch 63 is movably mounted on the lock body 62 and cooperates with the lock head 61. The lock catch 63 has a locked state in which it engages with the lock head 61 and an unlocked state in which it disengages from the lock head 62. The user pushes the flip frame 3 to engage or disengage the lock head 61 and the lock catch 63. When the lock catch 63 is in the locked state, the display screen 4 remains in the closed state. When the lock assembly 6 is in the unlocked state, the display screen 4 is pushed out by the pusher 5 and flipped to form a flipped state.

[0033] like Figure 5 and Figure 6 As shown, the lock body 62 includes a lock shell 621 and a cover plate 622. A mounting cavity 623 is provided in the lock shell 621. The cover plate 622 is fixed at the upper opening of the mounting cavity 623. The lock catch assembly 6 also includes a lock core 64, an elastic member 65, and a limit hook 66 arranged in the mounting cavity 623. The lock core 64 is movably arranged on the lock shell 621. The elastic member 65 is a spring installed between the lock core 64 and the lock shell 621, and is used to drive the lock core 64 toward the side where the lock head 61 is located. To move, one end of the limit hook 66 is hooked on the lock core 64, and the other end is hooked on the lock shell 621. The lock core 64 is provided with a limit groove 641 for the limit hook 66 to move. The limit groove 641 is heart-shaped and has a first limit point 642 and a second limit point 643. When the limit hook 66 is hooked on the first limit point 642, the lock buckle 63 is in a locked state; when the limit hook 66 is hooked on the second limit point 643, the lock buckle 63 is in an unlocked state. Figure 6 The position shown is unlocked.

[0034] like Figure 6As shown, the lock head 61 in this embodiment has a spherical portion 611 on one side facing the lock catch 63, and a plate-shaped portion 612 on the other side to facilitate fastening to the flip frame 3. The lock catch 63 includes a pair of symmetrically arranged claws 631 and 632. Taking the claw 631 as an example, the claw 631 has a mounting end 6311 and a locking end 6312. The mounting end 6311 is mounted on the lock core 64, which has a pair of mounting posts 644. The mounting ends of the pair of claws are respectively mounted on the mounting posts 644, and both mounting posts 644 are mounted with torsion springs 645. The locking end 6312 is formed with a locking groove 6313 for locking on the spherical portion 611 of the lock head 61. The locking end 6312 of the pair of claws can be closed and opened by moving the lock core 64. A stopper 646 is provided on the front side of the mounting post 644 of the lock core 64, embedded between the mounting ends 6311 of the pair of pawls. The side of the stopper 646 facing the mounting ends 6311 is shaped to match the outer contour of the mounting ends 6311. Guide rollers 647 are also provided on either side of the pair of pawls within the lock housing 621 of the lock body 62. Slideways 6314 that mate with the guide rollers 647 are provided on the sides of the pair of pawls 631 and 632. A guide groove is defined along the circumference of the guide rollers 647, into which the slideways 6314 extend.

[0035] like Figure 6 and Figure 7 As shown, the lock core 64, the inner ends of a pair of claws, the elastic member 65, the limiting hook 66 and the guide roller 647 are all installed in the installation cavity 623. The lock shell 621 is provided with a through hole 6211 on the side facing the lock head 61 for the buckling end 6312 to extend out. The buckling end 6312 extends out of the through hole 6211 to cooperate with the lock head 61.

[0036] The working principle of the locking assembly 6 is as follows:

[0037] by Figure 6 The position shown is used as the initial position. At this time, the limit hook 66 is hooked on the second limit point 643, and the lock buckle 63 is in the unlocked state. When the lock head 61 is pushed into the buckling end 6312 by pressing the flip frame 3, the lock buckle 63 moves inward with the lock core 64. During this process, the limit hook 66 will move from the second limit point 643 to the first limit point 642 along the side channel of the heart-shaped limit groove 641, and the two buckling ends 6312 of a pair of claws are closed to buckle the lock head 61. When the lock buckle 63 is in the locked state, the display screen 4 remains in the closed state.

[0038] The user presses the flip frame 3 inward again, and the limit hook 66 will move from the first limit point 642 to the second limit point 643 along the other side channel of the heart-shaped limit groove 641. During this process, driven by the elastic force of the elastic member 65, the lock core 64 moves forward, the lock buckle 63 moves forward, and the two buckling ends 6312 are opened, so that the lock head 61 is separated from the lock buckle 63. Under the action of the pushing member 5, the flip frame 3 is pushed to flip together with the lock head 61, and the display screen 4 can remain in the flipped state.

[0039] In this embodiment, if Figure 2 As shown, a connecting arm 21 is further provided on the mounting frame 2, and a rotating arm 31 is provided above the flip frame 3. One end of the rotating arm 31 is connected to the connecting arm 21 through a rotating shaft 22. The pushing member 5 is a pair of small-torque hydraulic push rods arranged on the left and right. The upper end of the hydraulic push rod is installed on the rear side of the mounting frame 2, and the lower end is fixed to the bottom of the flip frame 3 through a mounting member 51, so that when the flip frame 3 is pushed to flip, the lower side of the flip frame 3 can be flipped outward with the upper rotating shaft 22 as the rotating axis, so that the display screen 4 is in a tilted flip state.

[0040] like Figure 2 As shown, the flip frame 3 has a front plate 32, a rear plate 33 and a bottom plate 34. The front plate 32 is used to install the display screen 4 and the hydraulic push rod, and the rear plate 33 is used to install the lock head 61. The bottom plate 34 connects the front plate 32 and the rear plate 33, and the connection between the bottom plate 34 and the rear plate 33 extends obliquely downward to form a blocking limit portion 35. When the flip frame 3 is pushed by the hydraulic push rod to flip, the blocking limit portion 35 can be abutted against the rear side of the front frame 24 of the mounting frame 2, thereby limiting the flipping angle of the flip frame 3.

[0041] In this embodiment, the rotation center of the display screen 4 is defined by the rotation center point of the rotating shaft 22 of the rotating arm 31 above the flip frame 3. A low-torque hydraulic push rod on each side provides the power for flipping. When the display screen 4 is vertical, it is closed. A locking assembly 6 located in the middle of the lower ends of the two hydraulic support rods acts as a securing mechanism, maintaining the display screen 4 in the vertical position. Pressing the center of the display screen 4 triggers the separation of the locking head 61 and the locking catch 63 of the locking assembly 6. Once separated, the force of the hydraulic push rod is released, allowing the display screen 4 to begin flipping around the rotation center point, following the flip frame 3. At the end of the flipping motion, a blocking stop 35 located at the bottom of the flip frame 3 limits the flipping (rotation) angle.

[0042] <Example 2>

[0043] This embodiment is basically the same as the above embodiment 1, except that: Figure 8As shown, the pusher 5 is a torsion spring mounted on the rotating shaft 22, and the torsion spring has a first end 521 and a second end 522. The first end 521 is abutted on the connecting arm 21, and the second end 522 is abutted on the rotating arm 31. The elastic force of the torsion spring 52 is used to cause the flip frame 3 to rotate.

[0044] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
