[0027] As attached Figure 1-11 The shown embodiment is a flat door panel assembly for a pull-out rice cooker, comprising a sliding pot rack 2 slidably installed in the rice cooker 30 via a slide rail 1, wherein there are two slide rails 1 which are symmetrically fixed on the side walls on both sides of the inner cavity of the rice cooker 30, wherein each slide rail 1 is made of sheet metal bent into a U shape, and the bottom of the U-shaped structure is fixedly installed on the inner cavity side wall of the rice cooker 30 via screws to form a side-lying U-shaped structure, wherein the two side walls of the U-shaped structure respectively form an upper sliding portion 3 and a lower sliding portion 4, and the upper sliding portion 3 is located directly above the lower sliding portion 4, and a guide pulley 5 is rotatably installed at the front end of the lower sliding portion 4, and a pot rack limit plate 7 for limiting the maximum sliding stroke of the pot rack pulley 6 is fixedly installed on the slide rail 1 at the rear side of the guide pulley 5.

[0028] The sliding pot rack 2 includes a pot rack side beam 8 and a pot rack rear beam 9. The pot rack side beam 8 has two, and the two pot rack side beams 8 correspond to the two slide rails 1 one by one. The top of each pot rack side beam 8 is bent to form a hanging edge 10. The rear end of the hanging edge 10 is fixedly installed with a pot rack pulley 6. The pot rack pulley 6 includes a wheel frame 11 and a roller 12. The roller 12 is rotatably installed on the wheel frame 11. One side of the wheel frame 11 is an opening, and the other side of the wheel frame 11 is provided with a perforation. The size of the roller 12 is larger than the wheel frame 11 so that the upper part of the roller 12 can extend from the opening of the wheel frame 11, and the lower part of the roller 12 can extend from the perforation to the outside of the wheel frame 11; the wheel frame 11 is fixedly installed to the hanging edge 1 0, a perforation matching the roller 12 is also provided on the hanging edge 10, the lower part of the roller 12 extends downward to pass through the hanging edge 10 and can be slidably connected with the lower sliding part 4, the hanging edge 10 and the pot rack pulley 6 are slidably installed between the upper sliding part 3 and the lower sliding part 4, and the lower surface of the hanging edge 10 is also slidably connected with the guide pulley 5, a hinged portion 13 is provided at the lower front end of the pot rack side beam 8, and a door panel 14 is rotatably installed on the hinged portion 13, the rear ends of the two pot rack side beams 8 are respectively fixedly connected to the two ends of the same pot rack rear beam 9, and the door panel 14 contacts the front end of the pot rack side beam 8 when it is flipped and closed, and the pot rack rear beam 9, the pot rack side beam 8 and the door panel 14 cooperate to form a pot placement position. A pull handle 15 is provided on the front side of the door panel 14, and a fixed hook 16 is provided on the rear side of the door panel 14. An active hook 17 is rotatably installed on the pot rack side beam 8 to cooperate with the fixed hook 16 to lock the door panel 14 in a flipped closed position. The active hook 17 is located below the guide rail pulley 5 and slidably cooperates with the guide rail pulley 5. The structure of the guide rail pulley 5 is the same as that of the pot rack pulley 6, so that the guide rail pulley 5 can also serve as a pressing structure 18 that can be operated to limit the active hook 17 to a cooperative state with the fixed hook 16. The fixed hook 16 is located below the active hook 17. The sliding pot rack 2 is also provided with a pot holder on the pot placement position, and the pot holder includes two pot rack reinforcement angles 19 and a pot clamping plate 20, and the two pot rack reinforcement angles 19 are respectively fixedly mounted to the angle formed by the pot rack rear beam 9 and the two pot rack side beams 8, and the side of the pot rack reinforcement angle 19 close to the pot inner 31 is an arc-shaped edge adapted to the edge of the pot inner 31; a first hinge 21 is fixedly mounted on the upper part of the rear side of the door panel 14, and the pot clamping plate 20 is mounted on the first hinge 21 on the rear side of the door panel 14 for rotation up and down, the size of the pot clamping plate 20 is adapted to the size of the sliding pot rack 2, and the side of the pot clamping plate 20 close to the pot inner 31 is an arc-shaped edge adapted to the edge of the pot inner 31, and the setting of the pot holder can fill the gap between the pot inner 31 and the sliding pot rack 2, so that the placement of the pot inner 31 is more stable, and at the same time, the strength of the sliding pot rack 2 can be improved. A second hinge 22 is fixedly mounted on the lower portion of the rear side of the door panel 14 , and the door panel 14 is rotatably mounted on the hinge portion 13 via the second hinge 22 .One end of a linkage rod 23 is also rotatably mounted on the hinged portion 13 of the pot rack side beam 8, and the other end of the linkage rod 23 is rotatably connected to the pot clamping plate 20. The hinged portion 13, the linkage rod 23, the pot clamping plate 20 and the door panel 14 form a quadrilateral linkage structure, and the linkage rod 23 is provided with a supporting limit column 24 for contacting and limiting the maximum flipping and opening stroke of the pot clamping plate 20, and the second hinge 22 is provided with a door panel limit frame 25 for contacting and limiting the maximum flipping and opening stroke of the door panel 14. When the door panel 14 is flipped open, the quadrilateral linkage structure deforms accordingly, so that the pot clamping plate 20 is attached to the door panel 14, so as to prevent the pot clamping plate 20 from extending upward when the door panel 14 is placed flat, which is easy to cause a collision and affect the placement of the pot 31, and also reduce the probability of collision damage.

[0029] As a preferred embodiment, the movable hook 17 includes a hook rocker 26 rotatably mounted on the pot rack side beam 8 of the sliding pot rack 2, and a heavy pressure hook portion 27 cooperating with the fixed hook 16 is fixedly mounted at the front end of the hook rocker 26 so that the weight of the front end of the hook rocker 26 is greater than that of the rear end, and an unlocking pressure plate 28 is provided at the rear end of the hook rocker 26 to contact and cooperate with the guide rail pulley 5.

[0030] As a preferred embodiment, the rearmost end of the lower slide portion 4 is provided with a closed locking notch 29 that cooperates with the pot rack pulley 6 , and when the sliding pot rack 2 completely slides into the rice cooker 30 , the pot rack pulley 6 can sink into the closed locking notch 29 .

[0031] like Fig.12As shown, the door panel 14 assembly provided in this embodiment is installed in the rice cooker 30. The initial state is that the sliding pot rack 2 is completely pushed into the rice cooker 30 and the door panel 14 is completely flipped and closed. At this time, the guide rail pulley 5 presses the movable hook 17 to hook onto the fixed hook 16. When the sliding pot rack 2 is pulled out by hand by pulling the handle 15, the pot rack pulley 6 is stressed and disengaged from the closed locking notch 29. At this time, the center of gravity of the sliding pot rack 2 is on the inner side of the guide pulley 5, so the pot rack pulley 6 and the lower slide portion 4 slide and cooperate, and the sliding pot rack 2 is continued to be pulled out until the center of gravity of the sliding pot rack 2 crosses the guide pulley 5. At this time, the sliding pot rack 2 gradually swings slightly outward, and the pot rack pulley 6 and the upper slide portion 3 slide and cooperate, and then the sliding pot rack 2 is continued to be pulled outward until the pot rack pulley 6 contacts the pot rack limit plate 7, that is, the pulling out process of the entire sliding pot rack 2 is completed, and the relative sliding of the sliding pot rack 2 and the slide rail 1 is smoother through the cooperation of the guide pulley 5 and the pot rack pulley 6. During the pulling process, since the weight of the front end of the hook rocker 26 is greater than the rear end, under the action of gravity, the heavy pressure hook portion 27 will always be hooked on the fixed hook 16, and the door panel 14 cannot be flipped open until the unlocking pressure plate 28 contacts the guide rail pulley 5. Under the action of the pulling force, the guide rail pulley 5 presses the rear end of the hook rocker 26 downward through the unlocking pressure plate 28, and the heavy pressure hook portion 27 is separated from the fixed hook 16. The door panel 14 can be flipped open by pulling the handle 15 downward. At this time, the pot core 31 can be taken and placed. After taking and placing the pot core 31, the door panel 14 can be flipped and closed again, and the sliding pot rack 2 can be pushed into the rice cooker 30.

[0032] When the pulled out sliding pot rack 2 is pushed into the rice cooker 30 by hand, the sliding pot rack 2 and the pot rack pulley 6 will slide into the rice cooker 30. When the unlocking pressure plate 28 is separated from the guide rail pulley 5, the heavy pressure hook 27 re-hooks the fixed hook 16 under the action of gravity, so that the door panel 14 cannot be flipped open. When the center of gravity of the sliding pot rack 2 crosses the guide rail pulley 5, the pot rack pulley 6 moves slightly downward and slides with the lower descending part 4. When the pot rack pulley 6 slides to the closed locking notch 29, it will sink into the closed locking notch 29 under the action of gravity, forming an automatic return and locking effect, which can prevent the sliding pot rack 2 from sliding out by itself. In addition, the guide rail pulley 5 can act as a rotating fulcrum, making the swing of the pot rack side beam 8 smoother, so that the action of the pot rack pulley 6 falling into and out of the closed locking notch 29 is more stable and smooth, improving the user experience.

[0033] The above-mentioned embodiment only expresses one implementation method of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
