Description

Technical Field

[0001] This utility model relates to the field of kitchen cooking appliances, and in particular to an automatic cooking pot suitable for gas stove cooking machines and induction cooker cooking machines. Background Technology

[0002] The driving force for stir-frying comes from an automatic stir-fry pan directly below the heating source at the bottom of the pan. Its operation typically involves the pan itself remaining stationary, while a rotating shaft at the center of the bottom drives a spatula inside the pan to rotate and stir-fry. Existing technologies have the following main shortcomings: For example, in Chinese patent CN201621119476, ribs are used on the pan wall to disturb the food. This structure requires a special mold and has limited effectiveness for large-diameter pans. The spatula has a complex curved shape and uses a cast aluminum substrate coated with a polytetrafluoroethylene non-stick layer, which makes cleaning difficult, the non-stick layer easily peels off, and the low strength of the aluminum material results in a large and tall spatula, often only pushing the food to rotate, leading to poor even stirring and heating. Another example is Chinese patent CN202110312540, which uses a hexagonal fit between a rotating shaft seat and an external anti-rotation sleeve to prevent rotation. This method requires a large amount of machining, high precision, large parts, material waste, and is not conducive to compact design. Therefore, the present invention aims to provide a more easily processed and more compact anti-rotation solution, while optimizing the structure of the automatic cooking pot to achieve better performance. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the existing technology by providing an automatic cooking pot suitable for gas stove and induction cooker cooking machines. This invention enables even stirring and heating of ingredients, simplifies the structure and manufacturing process, reduces production costs, facilitates cleaning during use, prevents the non-stick layer from peeling off or failing, allows for easy replacement of the anti-stick sleeve after wear, and extends the lifespan of the cookware.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses an automatic cooking pot suitable for gas stove and induction cooker cooking machines, comprising a pot body, a handle, a rotating shaft seat, a rotating shaft, a rotating shaft sleeve, and a spatula. The pot body is a deep pot with a flat bottom and steep walls. The rotating shaft seat is fixedly connected to the bottom of the pot body, and the inner wall of the rotating shaft seat is provided with anti-rotation protrusions for cooperating with an external anti-rotation sleeve to prevent the pot body from rotating. The spatula is a stainless steel profile bent into a triangular cross-section, with its length extending from the center of the pot to the arc transition between the bottom and the wall of the pot. It is located at one end of the center of the pot and is connected to the rotating shaft and the rotating shaft sleeve at the top, rotating synchronously with the rotating shaft to stir-fry the food. The metal surfaces of the rotating shaft seat, the rotating shaft sleeve, and the spatula that come into contact with the food are covered with an easy-to-remove anti-stick sleeve.

[0005] The pot body described in this utility model is a flat-bottomed, steep-walled deep pot with an outward-flaring trumpet-shaped upper wall and a steep, straight lower wall; the pot body has a diameter of 20-30cm, a depth greater than 9cm and not greater than half the diameter of the pot body, and an angle between the lower section of the pot wall and the bottom plane of the pot range of 90-100 degrees.

[0006] In this invention, the rotating shaft seat is fixed to the bottom of the pot body by an interference fit.

[0007] In this invention, the rotating shaft seat is fixed to the bottom of the pot body via a threaded connection.

[0008] The anti-rotation protrusion described in this invention is a welded metal protrusion.

[0009] The cross-section of the shovel described in this invention is an equilateral triangle with a side length ranging from 6 to 8 mm.

[0010] The end of the spatula at the center of the pot described in this utility model is processed into a square block. An axial vertical groove is opened at the top of the rotating shaft. The square block is inserted into the top center groove of the rotating shaft sleeve and the axial vertical groove at the top of the rotating shaft, and then welded together to form a crossbeam inside the rotating shaft sleeve, which is used to transmit torque.

[0011] The anti-stick sleeve described in this utility model is a tube sleeve made of food-grade silicone.

[0012] In this utility model, the anti-stick sleeve covering the rotating shaft sleeve has an installation hole at the connection position between the rotating shaft sleeve and the shovel for inserting the shovel body.

[0013] The design principle of this utility model is as follows: This invention primarily improves the uniformity of food stirring and heating by optimizing the pot's shape, the spatula structure, the anti-rotation structure, and coordinating with the motor's rotation control. More specifically, driven by an external motor, the rotating shaft rotates, transmitting torque through the crossbeam within the shaft sleeve. This causes the shaft sleeve and the spatula, welded together, to rotate synchronously, automatically stirring the food and ensuring even heating. Simultaneously, the anti-rotation protrusion welded to the inner wall of the shaft seat engages with the notch on the outer anti-rotation sleeve to prevent the pot from rotating. This anti-rotation protrusion design requires only a simple weld of a single protrusion to the inner wall of the shaft seat, achieving the same effect as the original hexagonal anti-rotation design. This simplifies the complex multi-faceted fit into a single-point fit, significantly reducing processing precision requirements and manufacturing costs.

[0014] Because the spatula in this invention is made of high-strength, high-temperature resistant, and easy-to-weld stainless steel profile, it can be designed with a small volume and simple cross-section to meet the strength requirements. That is, the spatula of this invention is simplified into a low equilateral triangle with acute angles on both sides. This high-strength, non-deformable, small-volume spatula with a height of less than 7mm and acute-angled shovel corners makes it easier for food to pass over the spatula when rotating, and collide and flip over when passing over the spatula, achieving a stir-frying effect. At the same time, the length of the spatula extends from the center of the pot along the radial direction to the arc transition between the bottom of the pot and the pot wall, that is, the length of the spatula covers the entire radius. The food in the pot is effectively disturbed during each rotation of the spatula. In addition, the spatula is close to the bottom of the pot, so no food can stay for a long time without being disturbed, which can prevent the food from sticking to the bottom of the pot.

[0015] The pot in this invention is designed as a flat-bottomed, steep-walled, deep pot. The flat bottom makes it suitable for both gas stove and induction cooker cooking; the deep pot ensures that food won't be thrown out by the centrifugal force generated by the rotating spatula, while also providing sufficient volume to hold the food; the steep walls facilitate the accumulation of food against the pot walls under centrifugal force, and when the food accumulated at the bottom is removed by the rotating spatula, the food at the top quickly falls to the bottom due to the lack of support from the steep walls, thus achieving continuous stirring. Even if the pot's shape is drum-shaped (with an inwardly constricted upper wall) or the upper wall is outwardly flared, as long as the lower section of the pot wall is steep, it will still provide excellent stirring results.

[0016] This invention also covers the metal surfaces of the rotating shaft seat, rotating shaft sleeve, and spatula that come into contact with food with anti-stick sleeves to isolate and prevent food from sticking to the metal. The anti-stick sleeves are made of food-grade silicone tubing with a certain degree of elasticity, featuring high temperature resistance up to 250℃, good non-stick properties, and easy cleaning. Their inner diameter is slightly smaller than the outer diameter of the aforementioned components. They are fixed by being stretched and then fitted together, relying on their own elasticity to hold them in place. When replacing, they can be removed by simply applying axial force. The anti-stick sleeve on the rotating shaft sleeve has a small hole at the connection point between the rotating shaft sleeve and the spatula to allow the spatula body to pass through. The use of anti-stick sleeves eliminates the problems of traditional non-stick coating peeling and anti-stick failure. When they age or become damaged, they are easy to replace, greatly improving the overall service life of the cookware.

[0017] Furthermore, the spatula in this invention has its center end of the pot processed into a cube through hot pressing or grinding. This cube is inserted into the top center slot of the rotating shaft sleeve, and then welded to form a crossbeam inside the rotating shaft sleeve. Simultaneously, the spatula and the rotating shaft sleeve are welded together to form a single unit. During assembly, the rotating shaft sleeve is inserted onto the rotating shaft, and the crossbeam inside the sleeve fits perfectly into the axial vertical groove at the top of the rotating shaft. When the rotating shaft rotates, the crossbeam transmits torque, causing the rotating shaft sleeve and the spatula to rotate synchronously and stir-fry the food. Thus, the transmission of the motor's rotational power within the pot is: external motor rotational power → rotating shaft → crossbeam inside the rotating shaft sleeve → rotating shaft sleeve → spatula → stir-frying food. This plug-in connection structure between the rotating shaft and the rotating shaft sleeve reliably transmits the motor's forward and reverse rotation power while allowing the entire spatula assembly (including the rotating shaft sleeve and the spatula) to be removed from the rotating shaft, greatly facilitating cleaning and maintenance.

[0018] The beneficial effects of this utility model are: By simplifying the anti-rotation structure, optimizing the shape of the spatula and the pot body, and adopting a detachable anti-stick sleeve, the spatula's quick-release design achieves the goals of easy pot processing, even stirring and heating, convenient anti-stick maintenance, easy cleaning, and extended service life.

Anti-stick sleeve; 8. Weld. Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Example

[0027] like Figures 1 to 5 As shown, the automatic cooking pot of this embodiment has a pot body 1 with a diameter of 24cm, a bottom inner diameter of 24cm, and a depth of 11cm. It is a flat-bottomed, steep-walled deep pot (the angle between the lower section of the pot wall and the inner plane of the pot bottom is 90 degrees, which is a steep wall), and a hole is opened in the center of the pot bottom.

[0028] The rotating shaft seat (3) is fixed to the opening at the bottom of the pot by an interference fit between the stainless steel rotating shaft seat hole rod (3.1a) and the rotating shaft seat sleeve (3.2a). The rotating shaft seat hole rod (3.1a) has upper and lower stepped holes machined in the center.

[0029] An anti-rotation protrusion (3.1.1) is welded to the wall of the lower step hole.

[0030] The shaft (4) is fitted with clearance through the upper stepped hole of the shaft seat (3) and is limited by two snap rings (4.2). Multiple shaft sealing rings (4.1) are fitted on it for sealing. An axial vertical groove (4.3) is opened at the center of the top of the shaft (4).

[0031] The spatula (6) is made of stainless steel profile, which is made by bending a stainless steel equilateral triangular profile with a cross-sectional side length of 6mm. Its length extends from the center of the pot to the arc transition between the bottom of the pot and the pot wall. The end of its center is processed into a cube, which is inserted into the top center slot of the rotating sleeve (5) and then welded by the weld (8) to form a crossbeam (5.1) inside the rotating sleeve (5). At the same time, the spatula (6) and the rotating sleeve (5) are fixed together after being welded by the weld (8).

[0032] When the rotating sleeve (5) is inserted into the rotating shaft (4), the crossbeam (5.1) is stuck in the axial vertical groove (4.3). When the rotating shaft (4) rotates, the crossbeam (5.1) transmits torque, which drives the rotating sleeve (5) and the spatula (6) to rotate synchronously, transmit power, and stir-fry the ingredients.

[0033] Anti-stick sleeves (7) are fitted on the surface of the rotating shaft seat (3) located inside the pot, the rotating shaft sleeve (5), and the entire spatula (6). The anti-stick sleeve (7) is a food-grade silicone tube with a certain degree of elasticity. Its inner diameter is slightly smaller than the outer diameter of the spatula (6) and other components. It is fixed by being stretched and then fitted, and it holds tightly by its own elasticity. When replacing, it can be removed by directly applying axial force. The anti-stick sleeve on the rotating shaft sleeve (5) has a small hole at the connection position between the rotating shaft sleeve (5) and the spatula (6) so that the spatula body can pass through.

[0034] The handle (2) is installed on the side wall of the pot body (1).

[0035] In the automatic cooking pot described in Example 1, the pot body (1) is placed on the heating source (gas stove head or induction cooker panel) of the cooking machine during use. The lower end of the rotating shaft (4) is connected to the drive motor shaft of the cooking machine through the transmission inner sleeve, and the lower end of the outer anti-rotation sleeve is fixed to the frame of the cooking machine. This achieves stable operation in an automated cooking scenario.

[0036] Work process: The motor drive shaft of the external cooking machine is connected to the lower end of the rotating shaft (4) through the transmission inner sleeve, which drives the rotating shaft (4) to rotate; the rotating shaft (4) transmits torque through the crossbeam (5.1) in the axial vertical groove (4.3) at its upper end, which drives the rotating shaft sleeve (5) and the spatula (6) welded to it to rotate synchronously; at the same time, the upper end of the external anti-rotation sleeve extends into the lower step hole of the rotating shaft seat hole rod (3.1a), and its upper end notch engages with the anti-rotation protrusion (3.1.1) welded on the hole wall of the lower step hole, preventing the pot body (1) from rotating with the spatula and the food. The extended length and low height of the spatula (6) and the sharp angle design of its cross section effectively "sweep the bottom and cross the top" to turn the food. Combined with the centrifugal force generated by the rotating spatula and the "scraping" effect on the food at the arc transition of the bottom wall of the pot, the food accumulates at the steep wall and then loses support and automatically falls back to the bottom of the pot, thereby realizing the cycle of stir-frying. The anti-stick sleeve (7) effectively prevents sticking and can be replaced separately. Example

[0037] like Figure 6 As shown, the main difference between Embodiment 2 and Embodiment 1 lies in the fixing method of the rotating shaft seat (3). In this embodiment, the rotating shaft seat (3) is connected by a rotating shaft seat screw (3.1b) and a rotating shaft seat nut sleeve (3.2b) through threaded pre-tightening, and is clamped to the edge of the opening at the bottom of the pot body (1). The pot body (1) has a diameter of 24cm, a bottom inner diameter of 22cm, and a depth of 11.5cm. Its pot wall is also a steep wall (the angle between the lower section of its pot wall and the inner plane of the bottom of the pot is about 95 degrees, which is a steep wall). The structure, connection relationship and working principle of the other components are the same as those in Embodiment 1, and it also has the core features such as the anti-rotation protrusion (3.1.1), the stainless steel triangular profile spatula (6) and the detachable anti-stick sleeve (7).

[0038] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and concept of this utility model, should be included within the protection scope of this utility model.
