Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and specifically to an automatic tilting frying cooking pot.

Background Art

[0002] A frying cooking pot is a type of household appliance and an automated cooking device. Conventional frying cooking mainly relies on iron frying pans, especially those made of wrought iron or cast iron. Such pans can reach a high temperature in a short time due to their good thermal conductivity and high heat capacity, meeting the heat conditions required for high-fire frying. On the other hand, a frying cooking pot can automatically fry the ingredients in the pan, thereby reducing the workload of the cook.

[0003] The multifunctional frying cooking pot with Chinese Patent Application Number 202222117250.6 includes a case base, an inner pot, a pot lid, a stirring assembly, an electric heating assembly, and a control center. The pot lid is detachably attached to the case base and can cover the cooking chamber. A motor mounting part is provided on the pot lid. The stirring assembly includes a stirring motor and a stirring rod. The stirring motor is attached to the motor mounting part and is electrically connected to the control center. The output shaft of the stirring motor extends towards the cooking chamber. The stirring rod is detachably connected to the output shaft and can stir the ingredients in the cooking chamber. The stirring assembly of this invention is attached to the pot lid and can automatically perform stirring and frying. However, it is difficult to control the tilting angle during use of this frying cooking pot.

[0004] Conventional frying cooking pots are inconvenient to control the tilting angle during use. When frying ingredients, it is necessary to adjust the angle of the pot body to utilize the arc-shaped structure of the pot to throw up and scatter the ingredients from the bottom of the pot and then let them fall. However, if the angle of the pot is fixed or difficult to adjust, the ingredients will only be stirred on the flat surface of the bottom of the pot, resulting in insufficient and uneven stirring of the ingredients. Some ingredients are likely to be scorched because they contact the high-temperature bottom of the pot for a long time, while other ingredients are not heated sufficiently and remain undercooked or semi-cooked, seriously affecting the quality of the dish. [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] The purpose of this invention is to provide an automatic tilting stir-frying pan that has the advantage of being able to stir-fry evenly. Conventional stir-frying pans have the disadvantage of making it difficult to control the tilt angle during use. When stir-frying ingredients, it is necessary to adjust the angle of the pan body to use the curved structure of the pan to toss the ingredients up from the bottom of the pan, scatter them, and then drop them back down. However, if the angle of the pan is constant or difficult to adjust, the ingredients are only stirred on the flat surface of the bottom of the pan, resulting in insufficient and uneven stirring of the ingredients.

Modes for Carrying Out the Invention

[0018] Referring to FIGS. 1 to 11, the automatic tilting frying cooker includes a cooker top cover assembly 1, a base 17, and a pedestal assembly 21. The cooker top cover assembly 1 is rotatably attached to the top of the base 17, and the base 17 is rotatably attached inside the pedestal assembly 21.

[0019] Furthermore, a base inner cover 11 is fixedly attached inside the base 17, and an inner pot 9 for frying raw materials is rotatably connected inside the base inner cover 11.

[0020] Furthermore, a bidirectional motor bracket 13 is fixedly attached to the center of the bottom of the base 17. A bidirectional rotation motor 12 is attached to one side of the bidirectional motor bracket 13. A gear 14 is attached to the output shaft of the bidirectional rotation motor 12. An arc-shaped rack 18 is engaged with the surface of the gear 14, and the arc-shaped rack 18 is fixedly attached inside the pedestal assembly 21.

[0021] Furthermore, a fan assembly 2 and a heating element cover 4 are attached to the inner chamber of the cooker top cover assembly 1. The blades of the fan assembly 2 are located in the inner chamber of the heating element cover 4.

[0022] Furthermore, an infrared heating tube 5 is attached inside the heating element cover 4, and a heating tube protection cover 6 is fixedly attached to the bottom of the heating element cover 4.

[0023] Furthermore, a glass cover 3 is fixedly attached to the bottom of the inner chamber of the cooker top cover assembly 1, and the heating element cover 4 is fixedly attached to the top of the glass cover 3.

[0024] Furthermore, a fixing piece 15 is fixedly attached to the bottom of the base inner cover 11, and a synchronous motor 16 is fixedly attached to the bottom of the fixing piece 15. The output shaft of the synchronous motor 16 extends into the base inner cover 11, and a rotating block 10 is attached thereto.

[0025] Furthermore, the top of the rotating block 10 penetrates into the inner pot 9, and an inner pot fixing device 7 is attached to it. The synchronous motor 16 rotates the inner pot 9 inside the base inner lid 11 via the rotating block 10 and the inner pot fixing device 7. An inner pot sealing silicone rubber ring 8 is attached to the connection point between the inner pot fixing device 7 and the inner pot 9, and the inner pot sealing silicone rubber ring 8 seals the connection point between the inner pot fixing device 7 and the inner pot 9.

[0026] Furthermore, a forward-tilting microswitch assembly 19 and a vertical microswitch assembly 20 are mounted on both the left and right sides of the bottom of the base 17, and a vertical state positioning point and a tilt state positioning point are provided inside the base assembly 21, which are used in cooperation with the forward-tilting microswitch assembly 19 and the vertical microswitch assembly 20.

[0027] Furthermore, base fixing rings 23 are rotatably connected to both the left and right sides of the base assembly 21, and the base fixing rings 23 are fixedly attached to both the left and right sides of the base 17, and base decorative rings 22 are fixedly attached to both the left and right sides of the base assembly 21, and the base decorative rings 22 are located outside the base fixing rings 23.

[0028] Furthermore, an oil tray 24 is movably attached to the bottom of the base assembly 21.

[0029] Furthermore, a first oil hole 25 is provided at the bottom of the inner pot 9, and a second oil hole 26 is provided at the bottom of the base inner lid 11, with the second oil hole 26 located at the top of the oil drip tray 24.

[0030] In its initial state, the entire device is in either a vertical or tilted position, and the user selects the cooking mode via the operating interface. When starting a cooking program, if the device is in the vertical position, the vertical microswitch assembly 20 contacts and conducts with the vertical positioning point in the base assembly 21, and the control system recognizes the current state. When the rotation key is pressed, the bidirectional rotation motor 12 mounted on the bidirectional motor bracket 13 starts operating, and its output shaft rotates a gear 14, which meshes with an arc-shaped rack 18 fixed inside the base assembly 21, thereby driving the base 17 to slowly tilt and rotate within the base assembly 21.

[0031] When the base 17 rotates to the designed forward tilt angle, the forward tilt microswitch assembly 19 contacts and conducts to the forward tilt positioning point in the base assembly 21, and when the control system receives the signal, it stops the bidirectional rotary motor 12 and stabilizes the entire appliance in the forward tilt position. During the stir-frying process, the infrared heating tube 5 in the stove top lid assembly 1 generates heat within the heating element cover 4, efficiently heating the food below, and at the same time, the fan assembly 2 starts up, and its blades are located inside the heating element cover 4, forcing convection of the hot air, thereby improving the uniformity of heating. The glass lid 3 and the lower inner pot 9 form a relatively sealed cavity, effectively trapping heat and reducing heat energy loss.

[0032] Furthermore, a synchronous motor 16 located below the base inner lid 11 is activated, and its output shaft is inserted into the rotating block 10, causing the rotating block 10 to rotate. The rotating block 10 penetrates upward through the circular hole in the base inner lid 11, and its top end is connected to the inner pot fixing device 7, which allows the inner pot 9 to rotate stably within the base inner lid 11. The inner pot sealing silicone rubber ring 8 ensures a seal in the transmission part and prevents oil leakage. During rotation, the ingredients in the inner pot 9 are carried to the highest point by the convex structure of the pot body, and then fall freely to the bottom of the pot due to gravity, thus achieving continuous and uniform stir-frying and grilling.

[0033] During the cooking process, oil seeping from the ingredients flows out through the first oil hole 25 located at the bottom of the inner pot 9, passes through the second oil hole 26 corresponding to the bottom of the base inner lid 11, and finally drips into the retractable oil tray 24 at the bottom of the base assembly 21. In this way, automatic oil drainage is achieved, preventing the oil from repeatedly volatilizing at high temperatures and achieving the effect of smokeless cooking.

[0034] When cooking is complete or when it is necessary to switch states, the control system instructs the bidirectional rotary motor 12 to rotate in the reverse direction. The meshing of the gear 14 and the arcuate rack 18 causes the base 17 to rotate gradually from a tilted position to a vertical position. When the vertical microswitch assembly 20 is triggered and conducts again, the motor stops, completing the full cycle of automatic tilting and stir-frying. This entire process enables fully automated operation of heating, stir-frying, oil draining, and state switching, improving cooking efficiency and food quality.

[0035] The foregoing are merely preferred embodiments of the present invention and do not limit it. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention shall all be covered by the protection of the present invention.
