Detailed Implementation

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figure 1 , Figure 2 As shown, a specific embodiment of the present invention discloses a support structure, including a motor 410 and a lead screw 420; the lead screw 420 is rotatably supported by a bearing seat 430; the lead screw 420 has two threaded sections with opposite helical directions, and a sliding sleeve 440 is fitted at the threaded section, with a push block 450 installed on the top surface of the sliding sleeve 440; a support plate 460 is rotatably connected to the side of the push block 450 near the center of the lead screw 420, and the ends of the two support plates 460 are movably connected by a support plate 470; the lead screw 420 is driven by the motor 410, which drives the two sliding sleeves to move, thereby driving the support plate to move up and down.

[0019] The above structural design allows for deformation adjustment through the cooperation of a motor, a lead screw, and multiple movable connecting plates. When the two sliding sleeves move towards each other, the support plate in the middle position arches and rises smoothly, providing effective support. When the two sliding sleeves move in opposite directions to their ends, the multiple plates return to a flat state, without occupying too much external space, facilitating the overall layout. Furthermore, the use of a lead screw structure allows for more accurate displacement adjustment, with more precise height adjustment. On the other hand, it also has a certain self-locking effect, preventing easy displacement and providing stable support.

[0020] Furthermore, such as Figure 2As shown, the support plate 460 has protruding locking blocks 461 fixed at the middle of both ends. Both the ends of the support plate 460 and the locking blocks 461 have protruding arc-shaped structures. The push block 450 has a protruding arc-shaped end face near the support plate 460, and a first locking groove 451 at the middle position. The first locking groove has an arc-shaped concave structure that matches the shape of the locking block 461. Both ends of the support plate 470 have protruding arc-shaped structures, and a second locking groove 471 at the middle position. The second locking groove has an arc-shaped concave structure that matches the shape of the locking block 461. The shape is adapted; the locking blocks, the first locking groove, and the second locking groove are provided with holes for installing the pins; the locking blocks at both ends of the support plate are respectively locked in the first locking groove and the second locking groove, and are rotatably connected by the pins passing through the holes, and the connected ends abut against each other and slide; this structural design allows the push plate, support plate, and tray to be movably connected and fitted, and slide against each other at the connection points, reducing gaps, reducing heat loss and waste, and preventing food crumbs from splashing onto the lead screw during baking, maintaining the cleanliness of the lead screw and normal operation.

[0021] like Figures 3 to 6 As shown, the present invention also discloses an oven, including a body 100, a door 200, a baking tray 300, and a support structure 400; the bottom of the door 200 is rotatably connected to the bottom of the open opening of the body 100; the support structure 400 is installed on one side of the inner wall of the door 200; when the door 200 is opened to a flat position, the start motor 410 can be adjusted to move the tray 470 to the required height position to support the baking tray 300 that has been moved to the outside; The oven described above features a flip-down door that remains stationary when in a horizontal position, serving as a support base. The support structure, mounted on the door, supports the baking tray when it's raised to the desired height, ensuring a stable, suspended position without requiring complete removal of the tray. This frees up the hands for operation, improving overall efficiency and safety. When the support structure is retracted, it doesn't protrude from the door's outer wall and doesn't interfere with the oven's normal baking functions.

[0022] Furthermore, such as Figure 7 , Figure 8 As shown, the inner wall of the door 200 is provided with a groove 210 extending along the length direction; the support structure 400 is installed in the groove 210; when the push block 450, support plate 460, and tray 470 move to the straight position, they are flush with the inner wall of the door 200 and cover the exposed groove opening; the recessed groove is used as the installation part of the support structure so that it does not protrude and occupy space, making the whole more compact; and when the support structure is in the retracted state, it can cover the groove opening, which can reduce the impact of heat on the internal motor and prevent food crumbs from splashing onto the lead screw during baking.

[0023] Furthermore, recesses 211 are provided at both ends of the groove 210, and cover plates 220 are installed at the recesses 211; bearing seats 430 are fixedly installed at the bottom of the recesses 211 by bolts, and lead screw 420 is rotatably mounted between the two bearing seats 430; motor 410 is located below one of the cover plates 220 and is fixed to the groove wall by bolts; when the push block 450, support plate 460, and pallet 470 move to a position flush with the inner wall of the door 200, the end of the push block 450 abuts against... The push block, support plate, and tray, held on the side wall of the cover plate 220, block the groove at the slot between the two cover plates, forming a relatively tight blocking effect. The cover plate mainly insulates the motor. Even after the door is opened and the air supply is adjusted, the slot will open and some heat will enter the groove. However, the cover plate remains unchanged and can still provide heat insulation or protection to a certain extent. Among them, the motor is preferably a brushless motor, which can better adapt to high-temperature working environments and has a longer service life. Furthermore, such as Figure 10 As shown, the two opposite side walls of the housing 100 are provided with multiple sets of sliding grooves 110 for holding the baking tray 300; a first push switch 510 is installed on the end face of the sliding groove 110 away from the door 200 to monitor the movement of the baking tray at the sliding groove; as Figure 3 , Figure 5 As shown, a second push switch 520 and a third push switch 530 are embedded in the top surface of the cabinet door 200. The second push switch is used to start the support program; the third push switch is used to adjust the support height; furthermore, a fourth push switch is provided on the outside of the open opening of the cabinet. When the cabinet door is closed, pressure can be applied to the fourth push switch. Its protective function is to ensure that the support program cannot be started in this state, and the support structure will not extend and deform, avoiding contact and collision with the internal food or components.

[0024] Furthermore, such as Figure 6 , Figure 9 , Figure 10As shown, a boss is provided below the bottom of the opening of the box 100. Bosses 120 are fixedly provided at the top of both ends of the boss. A raised strip 230 is fixedly provided on the bottom surface of the box door 200. The length of the raised strip is adapted to the distance between the two bosses. One boss 120 has an insertion hole 130 on its wall surface near the center of the box. The other boss has a through hole 140 corresponding to it. An end cap 150 is internally threaded onto the end of the through hole 140 away from the insertion hole. A rotating shaft 160 is mounted between the end cap 150 and the insertion hole 130. A round hole 240 is provided on the raised strip 230, penetrating both ends. A countersunk hole 250 is provided near the end of the through hole 240. A prismatic groove 260 is provided at the end of the countersunk hole 250. The rotating shaft passes through the round hole and the raised strip. A prismatic block 161 is fixedly provided on the rotating shaft 160. The prismatic block 161 has a shape... The shape of the prism groove 260 is adapted to the shape and the position is corresponding, so that the rotating shaft and the box door rotate synchronously; the inner diameter of the through hole 140 is larger than the maximum outer diameter of the prism block 161, and the diameter of the through hole 140 is the same as the diameter of the countersunk hole 250. The inner wall of the through hole 140 near the insertion hole 130 is provided with a first wire hole 170 that communicates with the inner cavity of the box body 100; a second wire hole 270 is provided on the box door 200, one end of the second wire hole 270 communicates with the countersunk hole 250, and the other end extends to the groove 210; the wiring of the second push switch and the motor extends into the inner cavity of the box body through the second wire hole and the first wire hole for electrical connection; the above structural design allows the box door to be rotated and installed on the box body by the rotating shaft, which can meet the rotation support conditions and leave space for wiring and routing, so as to realize the required power connection and signal transmission.

[0025] Furthermore, such as Figure 3 As shown, a support strip 280 is fixedly installed on the top of the wall away from the box body of the box door 200, and the support strip extends along the length of the box door; the position of the support strip 280 corresponds to the position of the groove 210, and the groove sinks down to the support strip; the support strip 280 has a strip-shaped opening 290 that penetrates the upper and lower walls, and the edge of the opening is chamfered; the support strip provides the groove with a deeper recess, and the outside can also be used as a handle, which facilitates the overall design and layout; Furthermore, a first magnet block is fixedly embedded on the top surface of the tray; a second magnet block is fixedly embedded on both sides of the bottom surface of the baking tray; both the first and second magnet blocks are high-temperature resistant magnets; when the second magnet block moves to contact the first magnet block, they are magnetically attracted to each other; the magnet blocks can be samarium cobalt magnets or alnico magnets, which have very high Curie temperatures, up to 700°C, and excellent high-temperature stability; among them, samarium cobalt magnets are preferred under the operating conditions of the oven, as they are more stable and reliable in operation.

[0026] This invention also discloses a method of using an oven, which includes the following steps during baking: S1, Press the pause button to stop heating; S2, open the box door and flip it to a flat position; S3, press the second press switch to start the support program; S4, press the third press switch to move the support structure's tray to the desired height position; Alternatively, drag the baking tray outward to trigger the first press switch, causing the support structure's tray to move to the matching height position; S5, with the outer support of the baking pan placed on the tray, freeing your hands to handle baked goods; S6, after processing, the top baking tray moves inward to reset; S7, press the second press switch to reset the support structure; S8, close the oven door and restart the baking program; If multi-layer processing is required; An additional processing step is added between S6 and S7: press the third press switch to move the support structure tray to the required height position; and pull out the baking tray at the corresponding position to process the baked food accordingly.
