[0024] 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.

[0025] Please see Figure 1-7 The present invention provides a technical solution:

[0026] Example 1:

[0027] A cooking device includes a heating box 1, with several sets of heating tubes 2 fixedly connected inside the heating box 1. A cooking pot 3 is snapped into the heating box 1. The several sets of heating tubes 2 are arranged around the cooking pot 3. When the several sets of heating tubes 2 are turned on, the cooking pot 3 will be heated evenly. A box cover 4 is movably connected to the upper end of the heating box 1. A connecting plate 13 is provided on the lower side of the box cover 4. A first connecting cavity 14 is opened in the connecting plate 13. A cooking plate 15 is movably connected in the first connecting cavity 14. The lower end of the cooking plate 15 is set in a tooth-like shape. During the rotation of the cooking plate 15, the ingredients and seasonings will rotate. With the continuous heating of the cooking pot 3 by the several sets of heating tubes 2, the ingredients can be cooked. Two sets of first toothed rods 27 are fixedly connected to both sides of the cooking plate 15. The first toothed rods 27 mesh with one side of a gear 28. The gear 28 is movably connected in the connecting plate 13. The other side of the gear 28 meshes with a second toothed rod 32. Opening the telescopic rod 10 controls the cooking plate 15 connected to its output end to move into the first connecting cavity 14.

[0028] As the cooking plate 15 moves, it drives the first toothed rods 27 connected to both sides to move upward. The upward movement of the first toothed rods 27 drives the corresponding gears 28 to start rotating. The rotation of the gears 28 drives the second toothed rods 32 connected to the other side to start moving upward. The second toothed rods 32 are fixedly connected to one side of the cleaning tube 33. The cleaning tube 33 is movably connected to the second connecting cavity 29. The second connecting cavity 29 is opened in the connecting plate 13. Since the lower end of the cleaning tube 33 is tapered, the cleaning tube 33 will clean the bottom of the cooking pot 3. At the same time, the water sprayed from the cleaning tube 33 can wash away the impurities that have been cleaned.

[0029] The upper end of the cooking plate 15 is fixedly connected to the output end of the telescopic rod 10. The telescopic rod 10 is fixedly connected to the connecting shaft 12. The connecting shaft 12 is fixedly connected to the upper end of the connecting plate 13. The end of the connecting shaft 12 away from the connecting plate 13 is fixedly connected to the lower end of the water guide tank 7. The water guide tank 7 is movably connected to the relief groove 6. The relief groove 6 is opened in the lower end of the tank cover 4. A connecting ring 8 is movably connected to the upper end of the water guide tank 7. When the motor 5 is turned on, it will drive the water guide tank 7 connected to its output end to start rotating along the relief groove 6. At the same time, in order to prevent the water inlet pipe 9 from rotating with the water guide tank 7, a connecting ring 8 is movably connected to the upper end of the water guide tank 7. When the water guide tank 7 starts to rotate, the connecting ring 8 will move along the water guide tank 7 so that the water inlet pipe 9 connected to its upper end always stays in the original position.

[0030] A water inlet pipe 9 is fixedly connected to the upper end of the connecting ring 8. The end of the water inlet pipe 9 away from the connecting ring 8 extends out of the cover 4. A water guide pipe 11 is fixedly connected to the lower end of the water guide tank 7. The end of the water guide pipe 11 away from the water guide tank 7 is fixedly connected to the connecting plate 13 and is fixedly connected to two sets of telescopic pipes 30. The end of the telescopic pipe 30 away from the water guide pipe 11 is fixedly connected to the cleaning pipe 33. The external water pipe is connected to the water inlet pipe 9. The water source enters the water guide tank 7 through the water inlet pipe 9, and then enters the water guide pipe 11 through the water guide tank 7. Under the guidance of the water guide pipe 11, the water source enters the telescopic pipe 30. At this time, the water source in the telescopic pipe 30 enters the cleaning pipe 33 and is discharged through the through hole 31 opened at its lower end.

[0031] Example 2:

[0032] Based on Embodiment 1, in order to prevent the lid 4 from moving further after being closed, and to ensure that the wastewater after cleaning the cooking pot 3 can be discharged, T-shaped rods 26 are fixedly connected to both ends of the cooking plate 15. The T-shaped rods 26 are movably connected to the T-shaped grooves 34, which are opened in the first connecting cavity 14. A first spring 35 is fixedly connected in the T-shaped grooves 34, and the other end of the first spring 35 is fixedly connected to the T-shaped rods 26. When the cooking plate 15 moves upward, it will drive the T-shaped rods 26 connected to both ends to move upward synchronously along the T-shaped grooves 34. At this time, the first spring 35 located in the T-shaped grooves 34 is compressed. When it is necessary to return the cooking plate 15 to its original position and allow the two sets of cleaning tubes 33 to enter the second connecting cavity 29, the telescopic rod 10 is closed. Under the elastic force of the first spring 35, the cooking plate 15 will be popped out again.

[0033] The upper end of the water guide tank 7 is fixedly connected to the output end of the motor 5, and the motor 5 is fixedly connected inside the tank cover 4. The lower end of the cleaning pipe 33 is tapered, and several sets of through holes 31 are opened in the lower end of the cleaning pipe 33. One end of the heating box 1 is fixedly connected to a limiting block 23. A limiting cavity 22 is opened in the limiting block 23. A T-shaped locking rod 17 is slidably connected in the limiting cavity 22. A pull rod 21 is fixedly connected to the end of the T-shaped locking rod 17 away from the heating box 1. The end of the pull rod 21 away from the T-shaped locking rod 17 extends out of the limiting block 23. A second spring 20 is sleeved on the outside of the pull rod 21. One end of the second spring 20 is fixedly connected to the T-shaped locking rod 17, and the other end is fixedly connected to the limiting cavity 22.

[0034] The T-shaped locking rod 17 extends out of the limiting cavity 22 away from the pull rod 21 and then engages with the locking groove 18. The locking groove 18 is opened in the limiting rod 19, which is fixedly connected to the lower end of the box cover 4. Since the lower end of the limiting rod 19 is arc-shaped, and the locking end of the T-shaped locking rod 17 is also arc-shaped, the T-shaped locking rod 17 moves into the limiting cavity 22 under the pressure of the limiting rod 19. When the locking groove 18, which is opened in the lower side of the limiting rod 19, moves to the position of the T-shaped locking rod 17, the T-shaped locking rod 17 engages with the locking groove 18 under the elastic force of the second spring 20, and the box cover 4 is fixed.

[0035] A positioning groove 38 is provided in the lower end of the cooking pot 3. A T-shaped water guide block 24 is engaged in the positioning groove 38. A T-shaped guide rod 25 is fixedly connected to the lower end of the T-shaped water guide block 24. The lower end of the T-shaped guide rod 25 is movably connected to the guide cavity 37, which is located in the heating box 1. An electromagnet 36 is fixedly connected to the lower end of the guide cavity 37. A drain pipe 16 is fixedly connected to the lower end of the T-shaped water guide block 24. The end of the drain pipe 16 away from the T-shaped water guide block 24 extends out of the heating box 1. A third spring is sleeved on the outside of the T-shaped guide rod 25. 39. One end of the third spring 39 is fixedly connected to the T-shaped water guide block 24, and the other end is fixedly connected to the heating box 1. When the electromagnet 36 is turned on, the T-shaped guide rod 25 moves downward along the guide cavity 37. At this time, the T-shaped water guide block 24 moves downward along the positioning groove 38. At this time, the water source in the cooking pot 3 enters the drain pipe 16 through the T-shaped water guide block 24 and is discharged. When the cleaning is completed, the electromagnet 36 is turned off. At this time, under the elastic force of the third spring 39, the T-shaped water guide block 24 is re-locked into the positioning groove 38.

[0036] In addition, to achieve the above objectives, the present invention also provides a cooking system including the cooking apparatus described above.

[0037] Working principle: When in use, put the ingredients to be cooked and the corresponding seasonings into the cooking pot 3. After putting them in, close the lid 4 and insert the limiting rod 19 connected to one side into the limiting block 23. Since the lower end of the limiting rod 19 is arc-shaped, and the locking end of the T-shaped locking rod 17 is also arc-shaped, the T-shaped locking rod 17 moves into the limiting cavity 22 under the pressure of the limiting rod 19. When the locking groove 18 located in the lower side of the limiting rod 19 moves to the position of the T-shaped locking rod 17, the T-shaped locking rod 17 is locked into the locking groove 18 under the elastic force of the second spring 20. At this time, the lid 4 is fixed.

[0038] Turn on the motor 5 and several sets of heating tubes 2. After the heating tubes 2 are turned on, they will heat the cooking pot 3. The motor 5 rotates and drives the water tank 7 connected to its output end to rotate. The rotation of the water tank 7 drives the connecting shaft 12 to rotate. The rotation of the connecting shaft 12 drives the connecting plate 13 to rotate. The rotation of the connecting plate 13 drives the cooking plate 15 to rotate. Since the lower end of the cooking plate 15 is set in a tooth-like shape, the rotation of the cooking plate 15 will drive the food and seasonings to rotate. With the continuous heating of the cooking pot 3 by several sets of heating tubes 2, the food can be cooked. When the food is cooked, pull the lever 21 outward to drive the T-shaped locking lever 17 to move. The T-shaped locking lever 17 moves along the limiting cavity 22 and compresses the second spring 20. At this time, the T-shaped locking lever 17 disengages from the locking groove 18. At this time, the lid 4 can be opened. After releasing the lever 21, under the elastic force of the second spring 20, the T-shaped locking lever 17 returns to its original position. At this time, the cooked food can be taken out.

[0039] When cleaning of the cooking pot 3 is required, the telescopic rod 10 is opened to control the cooking plate 15 connected to its output end to move into the first connecting cavity 14. During the movement of the cooking plate 15, the first gear 27 connected to both sides moves upward. The upward movement of the first gear 27 drives the corresponding gear 28 to rotate. The rotation of the gear 28 drives the second gear 32 connected to its other side to move upward. At this time, the cleaning tube 33 located in the second connecting cavity 29 disengages. When both sets of cleaning tubes 33 are completely disengaged from the second connecting cavity 29, and the cooking plate 15 retracts into the first connecting cavity 14, the external water pipe is connected to the inlet pipe 9. The motor 5 is then turned on to make the connecting plate 13 rotate. During the rotation of the connecting plate 13, the two sets of cleaning tubes 33 move synchronously. The external water source enters the water tank 7 through the inlet pipe 9. Water enters the water guide tube 11 through the water guide tank 7. Guided by the water guide tube 11, the water enters the telescopic tube 30. At this time, the water in the telescopic tube 30 enters the cleaning tube 33 and is discharged through the through hole 31 at its lower end. Since the lower end of the cleaning tube 33 is tapered, the cleaning tube 33 will clean the bottom of the cooking pot 3. At the same time, the water sprayed from the cleaning tube 33 can wash away the impurities. When it is necessary to drain the water in the cooking pot 3, the electromagnet 36 is turned on to move the T-shaped guide rod 25 downward along the guide cavity 37. At this time, the T-shaped water guide block 24 moves downward along the positioning groove 38. The water in the cooking pot 3 enters the drain pipe 16 through the T-shaped water guide block 24 and is discharged. After cleaning is completed, the electromagnet 36 is turned off. At this time, under the elastic force of the third spring 39, the T-shaped water guide block 24 is re-locked into the positioning groove 38.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
