[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 8 As shown, the present invention provides an electric oven with a multi-functional baking tray and grill rack combination accessory, including a housing 100, and further including: a folding mechanism 200 disposed in the inner wall of the housing 100; a baking tray 500 installed in the inner wall of the housing 100 by a fixing mechanism 300; and a rotisserie fork 600 disposed in the inner wall of the housing 100 by a connecting mechanism 400. The folding mechanism 200 includes a fixed rod 202, a square block 211 elastically connected to the inner wall of the fixed rod 202 via a connecting spring 210, a rotating wheel 208 rotatably connected to the inner wall of the fixed rod 202, a pull rope 209 wound around the outer wall of the rotating wheel 208, a lever block 207 slidably connected to the inner wall of the fixed rod 202, a frame rod 201 slidably connected to the inner wall of the housing 100, a fixed block 204 fixedly connected to the inner wall of the frame rod 201, and a moving block 206 hinged to the outer wall of the fixed block 204 via a hinge rod 205.

[0021] like Figures 2 to 4 As shown, a slider 203 is fixedly connected to the outer wall of the support rod 201, and a square groove 212 is opened on the inner wall of the housing 100. The moving block 206 is slidably connected to the outer wall of the support rod 201. The above solution is adopted: the shell 100 is the main body of the electric oven, and the folding mechanism 200 can be folded up and unfolded. When unfolded, it can be used as a baking rack, while when folded, it can reduce the space occupied and improve the utilization rate of the internal space of the shell 100; both the baking tray 500 and the folding mechanism 200 can move vertically. When the baking tray 500 is below the folding mechanism 200, the baking tray 500 can be used to catch oil when the folding mechanism 200 is unfolded. When the baking tray 500 is above the folding mechanism 200, the baking tray 500 can be used and the folding mechanism 200 can be folded up, thus switching between independent use. When not in use, there is no need to remove the unused baking tray 500 or grill rack from the housing 100. After adjusting the position, it can be used directly, which is more convenient. There is also no need to place the removed baking tray 500 or grill rack on the outside, which will cause dust to fall on it. There are multiple sets of support rods 201. The innermost set of support rods 201 is slidably connected to the inner wall of the rear end of the housing 100 and can move vertically, while the front sets of support rods 201 can move horizontally to unfold and retract. The fixing rod 202 is set on the outermost side. When the fixing rod 202 is pulled, multiple sets of support rods 201 can be unfolded or retracted at the same time for use.

[0022] like Figures 2 to 4 As shown, the fixed rod 202 is in contact with the inner wall of the housing 100, the two ends of the hinge rod 205 are respectively hinged to the outer walls of the moving block 206 and the fixed block 204, the two ends of the pull rope 209 are respectively fixedly connected to the outer walls of the lever block 207 and the square block 211; one end of the connecting spring 210 is fixedly connected to the outer wall of the square block 211, the other end of the connecting spring 210 is fixedly connected to the inner wall of the fixed rod 202, the square block 211 is slidably connected to the inner wall of the fixed rod 202, and the square block 211 is engaged with the square groove 212.

[0023] The above scheme is adopted: Each set of support rods 201 has a sliding block 206 slidably connected to its outer wall, and a fixing block 204 fixed to its inner wall. The outer wall of the rear end of the fixing rod 202 is also slidably connected to a sliding block 206. In the folded state, the hinge rod 205 is retracted into the inner wall of the support rod 201, and the support rod 201 and the fixing rod 202 fit together to reduce space occupation. When unfolded, the hinge rod 205 flips, and the sliding block 206 slides along the outer walls of the support rod 201 and the fixing rod 202. Figure 3As shown, it can be unfolded and used as a grill. The square block 211 in the fixing rod 202 can be engaged with the square groove 212 under the elastic force of the connecting spring 210, fixing the position of the fixing rod 202. The square groove 212 is provided with two sets, one at the top and one at the bottom, and each set has two openings at the front and one at the back. When engaged with the rear square groove 212, it is in the folded state, and when engaged with the front square groove 212, it is in the unfolded state. The lever 207 can be manually pushed outward, driving the pull rope 209 to move synchronously with one end connected to it. At the same time, the pull rope 209 moves along the outer wall of the rotating wheel 208, causing the rotating wheel 208 to rotate, changing the direction of the pull force of the pull rope 209. Its other end will pull the square block 211 to move into the inner wall of the fixing rod 202. After it is disengaged from the square groove 212, the fixing rod 202 can be pulled back and forth to fold or unfold the folding mechanism 200. When moving vertically, the height of the folding mechanism 200 can be adjusted.

[0024] like Figure 5 and Figure 6 As shown, the fixing mechanism 300 includes a connecting block 301. A circular block 303 is elastically connected to the inner wall of the connecting block 301 via a telescopic spring 302. A trapezoidal block 305 is slidably connected to the inner wall of the connecting block 301. A slide rod 304 is slidably connected to the inner wall of the connecting block 301. A circular groove 307 is provided on the inner wall of the housing 100. A guide groove 308 is provided on the inner wall of the housing 100. A guide block 306 is fixedly connected to the outer wall of the baking tray 500.

[0025] Using the above scheme: the fixing mechanism 300 is used to fix the position of the baking tray 500. When using the folding mechanism 200 to bake larger food items, the baking tray 500 can be fixed at the bottom, and the folding mechanism 200 is fixed above the baking tray 500. When both the folding mechanism 200 and the baking tray 500 need to be used, if a larger food item is placed on the baking tray 500, the folding mechanism 200 can be moved upwards. When only the baking tray 500 needs to be used, the folding mechanism 200 is moved downwards, and the baking tray 500 is moved above the folding mechanism 200. Figure 6 As shown, it can be used immediately, which is quite flexible. It does not require removing the unused baking tray 500 or baking rack and placing it outside when switching between baking trays 500 and baking racks, which is quite convenient.

[0026] like Figure 5 and Figure 6 As shown, the connecting block 301 is fixedly connected to the outer wall of the baking pan 500, one end of the telescopic spring 302 is fixedly connected to the outer wall of the round block 303, and the other end of the telescopic spring 302 is fixedly connected to the inner wall of the connecting block 301; the round block 303 is slidably connected to the inner wall of the connecting block 301, the round block 303 is engaged with the round groove 307, the guide block 306 is in contact with the inner wall of the guide groove 308, one end of the slide rod 304 is fixedly connected to the outer wall of the round block 303, and the other end of the slide rod 304 is slidably connected to the outer wall of the trapezoidal block 305.

[0027] Using the above solution: the connecting block 301 is fixed by the telescopic spring 302 driving the round block 303 to engage with the round groove 307, thus fixing the position of the baking tray 500. The user can press the trapezoidal block 305 inward, and its inclined surface pulls the slide rod 304 to move. Since the slide rod 304 is fixed to the round block 303 and can only move laterally, it will drive the round block 303 to move towards the center into the inner wall of the connecting block 301, disengaging from the round groove 307, thereby releasing the fixing of the connecting block 301 to the baking tray 500 and moving it. When it is necessary to adjust the baking tray 500 to above the folding mechanism 200, first pull the baking tray 500 outward, and the guide block 306... Move along the inner wall of the guide groove 308, then move the baking tray 500 upwards and inwards. The baking tray 500 moves past the folding mechanism 200, so that the round block 303 corresponds to the position of the upper round groove 307. At this time, release the trapezoidal block 305, and the telescopic spring 302 drives the round block 303 to pop out and engage with the round groove 307 to complete the fixing of the baking tray 500. At this time, the folding mechanism 200 is below the baking tray 500. The round groove 307 is provided with two vertical sets, which can fix the baking tray 500 in the upper and lower positions. When using the baking tray 500, place it above the folding mechanism 200 to avoid the folding mechanism 200 blocking the heat and affecting the baking effect.

[0028] like Figure 7 and Figure 8 As shown, the connecting mechanism 400 includes a motor 401, the output shaft of the motor 401 is fixedly connected to a plug 402, the inner wall of the plug 402 is elastically connected to a wedge block 404 through a reset spring 403, the inner wall of the plug 402 is elastically connected to a partition 406 through a compression spring 405, the outer wall of the roasting fork 600 is provided with a groove 407, and the inner wall of the housing 100 is fixedly connected to a mounting base 408.

[0029] The above solution improves the fixing effect of the roasting fork 600 by connecting the connecting mechanism 400. The roasting fork 600 can fix the food and rotate it continuously, improving the uniformity of roasting. The cooperation between the baking tray 500, the grill and the roasting fork 600 makes the device more functional. One end of the roasting fork 600 can be placed on the mounting base 408, and the other end is fixed in the insert 402. The motor 401 drives the insert 402 to rotate, which in turn drives the roasting fork 600 to rotate synchronously. The wedge block 404 in the insert 402 can improve the fixing effect of the roasting fork 600 after engaging with the groove 407, and avoid the problem of wear gap between the hexagonal shaft of the roasting fork 600 and the insert after long-term use, which would affect the rotation.

[0030] like Figure 7 and Figure 8As shown, the motor 401 is fixedly connected to the inner wall of the housing 100. One end of the return spring 403 is fixedly connected to the outer wall of the wedge block 404, and the other end of the return spring 403 is fixedly connected to the inner wall of the insert block 402. The wedge block 404 is engaged with the groove 407. The roast fork 600 is in contact with the mounting base 408 and the insert block 402. One end of the compression spring 405 is fixedly connected to the outer wall of the partition plate 406, and the other end of the compression spring 405 is fixedly connected to the inner wall of the insert block 402. The partition plate 406 is slidably connected to the inner wall of the insert block 402, and the wedge block 404 is slidably connected to the inner wall of the insert block 402.

[0031] Using the above method: After one end of the roast fork 600 is placed on the mounting base 408, the other end can be inserted into the insert block 402. The arc surface of the wedge block 404 is pressed, causing the return spring 403 to contract. After the wedge block 404 moves into the inner wall of the insert block 402, the roast fork 600 is inserted and rotated so that the groove 407 corresponds to the position of the wedge block 404. The return spring 403 drives the wedge block 404 to pop out and engage with the groove 407 to complete the fixation. At this time, the roast fork 600 is in contact with the partition plate 406 but does not generate pressure. When removing the roast fork 600, it is pushed into the insert block 402, pressing the partition plate 406 to move inward. The compression spring 405 contracts, and the arc surface of the wedge block 404 is pressed by the inner wall of the groove 407 and moves back into the insert block 402. At this time, the roast fork 600 is manually rotated so that the positions of the wedge block 404 and the groove 407 are staggered, and the roast fork 600 can be directly removed. The operation is simple and the fixation effect is also good.

[0032] Working principle and usage process of this invention: When the grill is needed, the user can manually pull the lever 207 outward to move the pull rope 209 along the rotating wheel 208, which pulls the square block 211 to move and compress the connecting spring 210, and disengage it from the square groove 212 at the rear end of the inner wall of the housing 100. Then, the user can pull the fixing rod 202 forward to drive multiple sets of frame rods 201 to unfold simultaneously. The moving block 206 on the frame rod 201 slides, and the hinge rod 205 flips and unfolds. When the fixing rod 202 moves to the front position, the user can release the lever 207, and the connecting spring 210 will reset and push the square block 211 to engage with the front square groove 212, thus completing the unfolding and fixing of the folding mechanism 200. At this time, it can be used as a grill. In this state, the baking tray 500 is located below the folding mechanism 200 and can be used as an oil drip tray to prevent oil from dripping inside the housing 100.

[0033] When the baking tray 500 is needed, the user can manually pull the lever 207 outward and then push the fixing rod 202 backward, causing multiple sets of support rods 201 to retract synchronously. The hinge rod 205 folds and retracts into the inner wall of the support rod 201, and the multiple sets of support rods 201 and the fixing rod 202 fit together. When the fixing rod 202 moves to the rear position, the lever 207 is released, and the square block 211 is engaged with the rear square groove 212 under the action of the connecting spring 210, completing the retraction and fixing of the folding mechanism 200.

[0034] Next, press the trapezoidal block 305 inward to release the engagement between the round block 303 and the lower round groove 307; pull the baking tray 500 outward, and the guide block 306 slides along the guide groove 308 to the end. Then move the baking tray 500 upward past the folded mechanism 200. After it is above the folded mechanism 200, push the baking tray 500 inward. After it is in place, release the trapezoidal block 305. The round block 303 engages with the upper round groove 307 under the action of the telescopic spring 302, thus fixing the baking position of the baking tray 500. At this time, the folding mechanism 200 will not block the heat transfer to the baking tray 500.

[0035] When the baking tray 500 and the grill rack need to be used at the same time, the folding mechanism 200 can be adjusted so that the square block 211 engages with the square slot 212 above, with the baking tray 500 at the bottom. This allows larger food to be placed on the baking tray 500 and smaller food to be placed on the folding mechanism 200 for baking.

[0036] When the roasting fork 600 is needed, fix the food to be roasted on the roasting fork 600, place one end of the roasting fork 600 on the mounting base 408, align the other end with the insertion block 402 of the connecting mechanism 400 and insert it. During the insertion process, the roasting fork 600 presses the arc surface of the wedge block 404, causing the wedge block 404 to compress the return spring 403 and retract into the inner wall of the insertion block 402. When the roasting fork 600 contacts the partition plate 406, the roasting fork 600 can be rotated so that the groove 407 corresponds to the position of the wedge block 404. The return spring 403 returns to its original position and pushes the wedge block 404 to engage with the groove 407, thus completing the fixing of the roasting fork 600. At this time, starting the motor 401 will drive the roasting fork 600 and the food to rotate for roasting.

[0037] After baking, once the roasting fork 600 has cooled, push the roasting fork 600 towards the insert block 402. The roasting fork 600 presses against the partition 406, compressing the compression spring 405. At the same time, the arc surface of the wedge block 404 is squeezed by the inner wall of the groove 407, and the compression return spring 403 retracts into the inner wall of the insert block 402. The user can manually rotate the roasting fork 600 to make the wedge block 404 and the groove 407 intersect, and then pull the roasting fork 600 outward to complete the disassembly. The operation is simple and the fixing effect is good.
