Description

Technical Field

[0001] The invention relates to a cooking utensil, in particular to a cooking utensil with a stirring function. Background Art

[0002] In order to realize automatic cooking, especially to realize the automatic stir-frying function, a cooking utensil with a stirring device is known. Usually, a stirring device is arranged in the inner pot of the cooking utensil, and a motor and a transmission member driven by the motor are arranged in the cover body to drive the stirring device to move, thereby stirring the food in the pot. At the same time, during the stirring process, it is usually hoped that the stirred food can be turned over so that it is heated evenly. As described in CN107616676A, in order to turn over the food, the prior art may use the method of stamping the inner pot to form a protrusion, but the process is complicated and the turning effect cannot be guaranteed. The cooking utensil according to the invention includes a support frame mounted on the inner pot mouth, and a spoiler is provided on the support frame to block the food and make the food fully turn over.

[0003] However, in this invention, the support frame is relatively large, inconvenient to assemble and disassemble, and not easy to store when not in use. In addition, in some cases, such as when the cover of the cooking utensil has other functions, the motor driving the stirring device needs to be placed in the pot of the cooking utensil, and the lower end of the stirring device is connected to the driving device. In this case, the technical solution according to this invention is no longer suitable. Summary of the invention

[0004] The invention provides a cooking utensil, which is used for realizing an automatic stir-frying function in the cooking utensil with a driving device in the pot body, and enables the stirred food to be fully turned over.

[0005] Specifically, a cooking utensil according to the present invention comprises:

[0006] - the pot body, which contains the inner pot for holding the food and the driving device;

[0007] - a lid, which is openably and closably disposed on the pot body and defines a cooking space together with the inner pot;

[0008] - a stirring assembly, arranged to be mounted on the bottom of the inner pot and driven to rotate by the driving device;

[0009] It is characterized in that a protrusion is provided on the inner wall of the inner pot, the stirring assembly includes a stirring blade and a spoiler, the spoiler includes an axial mounting section, and the spoiler is installed above the stirring blade in a rotatable manner relative to the stirring blade through the axial mounting section, the spoiler is configured to be blocked by the protrusion and maintained in this position, and the stirring blade is configured not to contact the protrusion when rotating.

[0010] In the cooking utensil according to the present invention, the driving device is located in the pot body instead of being carried by the lid. It is understood that the bottom of the inner pot has a through hole for the driving device or the stirring assembly to pass through, so as to achieve the coupling of the driving device and the stirring assembly. Advantageously, the driving device is configured to drive the stirring assembly to rotate around the rotation axis. Preferably, the stirring assembly is detachably mounted in the inner pot. According to some embodiments, the cooking utensil can be equipped with a plurality of stirring assemblies that are interchangeable with each other to achieve different functions.

[0011] The so-called "stirring blade" can also be called "stirring blade", which may or may not have the function of cutting, and its main function is to stir the ingredients in the pot so that they move in the pot instead of staying in the same position. The stirring assembly according to the present invention also includes a spoiler, which is advantageously installed coaxially with the stirring blade. The spoiler is installed so that it can rotate relative to the stirring blade through the axial mounting section of the spoiler. When the stirring assembly is driven to rotate by the driving device, even if the spoiler is not in place at the beginning, it will rotate due to the friction between the stirring blade or being pushed by the food until the protrusion set in the inner pot blocks the spoiler and maintains it in the working position. The stirring blade continues to rotate around the axis under the drive of the driving device, thereby generating relative rotation between the spoiler and the stirring blade. In this working state, when the stirring blade pushes the food in the pot to move onto the spoiler, the spoiler, which is blocked by the protrusion of the inner pot and is fixed, will force the food to turn over or mix, thereby ensuring that the food is fully turned over, heated evenly and not easy to stick to the pot.

[0012] According to one embodiment of the present invention, the stirring assembly includes an axial limiter installed at the bottom of the spoiler, which is fixed to the top of the stirring blade so as to rotatably mount the spoiler above the stirring blade. As the name implies, the axial limiter limits the position of the spoiler in the axial direction so that the spoiler cannot move along the rotation axis of the stirring assembly. At the same time, the axial limiter also positions the axial mounting section of the spoiler on the stirring blade in a plane perpendicular to the axial direction, preferably on its rotation axis. In other words, the axial limiter cooperates with the axial mounting section to fix the spoiler to the top of the stirring blade. This fixing method ensures that only the freedom of relative rotation between the spoiler and the stirring blade along the rotation axis is retained.

[0013] According to one embodiment of the present invention, the axial limit member includes a sleeve and a limit ring, the outer wall of the axial mounting section is provided with an annular groove, the limit ring is installed in the annular groove, the sleeve is sleeved outside the axial mounting section and the limit ring, and the sleeve is fixed to the top of the stirring blade. More specifically, according to this embodiment, after the limit ring is installed in the annular groove, its outer diameter is greater than the outer diameter of the axial mounting section, and the top of the sleeve includes a return edge extending radially inward, and the limit ring abuts against the inner side of the return edge to achieve axial limitation of the spoiler. According to this embodiment, the shapes of the components are simple and easy to process. Alternatively, an integrally formed flange can be directly provided on the axial mounting section to replace the cooperation between the annular groove and the limit ring, or any other axial limit cooperation structure known to those skilled in the art can be adopted.

[0014] According to one embodiment of the present invention, the top of the mixing blade includes an L-shaped slot, the interior of the sleeve includes a retaining rib, and the sleeve can be rotated to a position where the retaining rib is inserted into the slot, thereby fixing the sleeve in the axial and circumferential directions. In this way, the sleeve can be easily installed on the top of the mixing blade and can also be easily removed, thereby making it easy to remove the spoiler, which helps to achieve a variety of cooking methods and is easy to clean. Alternatively, any other known detachable fixing method can be used to fix the sleeve, such as a threaded connection.

[0015] According to one embodiment of the present invention, an axial protrusion is provided at the top of the mixing blade, and a hollow section is provided at the bottom of the axial mounting section of the spoiler, and the hollow section is sleeved on the axial protrusion. Although the axial mounting section of the spoiler is sleeved outside the axial protrusion at the top of the blade holder, the axial protrusion does not produce a circumferential constraint on it, but only plays a positioning role. In other words, the cooperation between the axial mounting section and the axial protrusion allows the two to generate relative rotation around the axis of rotation. Alternatively, the axial protrusion can also be set as a hollow section and the axial mounting section can be inserted into it for positioning.

[0016] According to one embodiment of the present invention, the spoiler includes a spoiler blade, and the spoiler blade includes a first section extending obliquely upward from the axial mounting section and a second section extending downward from the apex of the first section, and the second section is blocked by the protrusion of the inner pot. It can be understood that the axial mounting section is located on the rotation axis of the stirring assembly and has a relatively low height, while the spoiler blade is fixed to the axial mounting section. In order to expand the effective spoiler area, the first section extends obliquely upward, while the second section extends downward close to the side wall of the inner pot. The first section and the second section as a whole form a shape similar to a ram's horn. The height and radial position of the apex of the first section can be set according to actual needs.

[0017] According to one embodiment of the present invention, when the second section is blocked by the protrusion of the inner pot, the first section and the second section respectively disturb and stir the food rotating in the inner pot while being stirred by the stirring blade. In fact, when the second section of the spoiler blade contacts the protrusion, the height and thickness combination formed by the two will disturb and stir and flip the food on the side of the inner pot. At the same time, since the spoiler blade remains stationary, the rotating food and the spoiler blade have relative motion, so the first section and possible second section of the spoiler blade also play a role in stirring the food.

[0018] Advantageously, when the spoiler is mounted on the stirring blade, the height of the apex of the first section is at least half the height of the inner pot. This ensures that the lower portion of the food being stirred in the pot can pass under the spoiler blade, while the upper portion of the food is driven to move and stirred by the spoiler blade due to the relative movement. If the apex of the first section is set too low, the upper portion of the food cannot be stirred.

[0019] According to an embodiment of the present invention, the inner pot includes two protrusions, and the spoiler includes two spoiler blades whose positions correspond to the two protrusions. The number and position of the protrusions correspond to the spoiler blades, and there may be only one or more than two protrusions. When the number of protrusions is greater than or equal to two, they are preferably evenly distributed along the circumference of the inner pot.

[0020] Further, according to an embodiment of the present invention, the two protrusions are arranged at radially opposite positions in the inner pot, and the two spoiler blades of the spoiler are at an angle of 180° to each other. This arrangement has a simple structure, balanced force, and good effect.

[0021] According to one embodiment of the present invention, the protrusion is fixed on the inner side wall of the inner pot. The protrusion can be a separately processed component, fixed to a suitable position on the inner side wall of the inner pot by rivets or other attachment devices. Of course, the protrusion can also be integrally formed with the inner pot, for example, made by stamping or other processes. The inner side wall of the inner pot refers to the wall portion other than the bottom wall, which can be a cylindrical side wall close to the pot mouth, or a circular arc segment connecting the bottom wall and the cylindrical side wall. For example, the protrusion can be fixed at the top of the circular arc segment.

[0022] According to one embodiment of the present invention, the stirring knife includes a knife seat and a stirring blade fixed to the knife seat, and a driving shaft assembly connected to the driving device is provided at the bottom of the inner pot, and the knife seat is driven to rotate by the driving shaft assembly and can be removed from the driving shaft assembly. According to one embodiment of the present invention, the driving shaft assembly includes a driving shaft protruding upward, and the knife seat of the stirring knife is fastened to the driving shaft in a detachable manner, for example, by an interference fit. Specifically, the driving shaft assembly passes through the through hole at the bottom of the inner pot and is directly or indirectly connected to the driving device arranged in the pot body to provide rotational power.

[0023] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices, systems, equipment, and methods consistent with some aspects of the present invention.

[0038] Figure 1 FIG. 2 shows an overall external view of a cooking appliance according to the present invention. The cooking appliance may be an electric rice cooker, an electric pressure cooker or an electric heating appliance with a baking function, in particular, a multifunctional cooking machine. Figure 1 As described, the cooking utensil includes a pot body 10 and a lid 20. The lid 20 is openably and closably disposed on the pot body 10 to close the cooking space. The pot body 10 accommodates an inner pot 12 for holding food and typically includes a heating mechanism such as a resistor, which may be disposed below or near the inner pot 12. At the same time, a baking device (not shown), such as a heating mechanism, an air duct, and a fan, may be disposed in the lid 20 of the cooking utensil according to the present invention to achieve the baking function of the cooking utensil. In addition, in order to achieve cooking functions such as frying and stewing, the pot body 10 also accommodates a driving device 14 (see Figure 5 ) to drive the stirring assembly 30 installed in the inner pot 12 to rotate to stir the ingredients evenly.

[0039] Figure 2 1 shows a top view of the pot body 10, which includes an inner pot 12 with a stirring assembly 30 installed. Figure 2 As shown, two protrusions 122 are provided on the inner wall of the inner pot 12, and their positions are opposite to each other in the radial direction. The stirring assembly 30 is installed at the center of the inner pot 12, and includes a stirring blade 32 and a spoiler 34. Figure 2 The working position of the stirring assembly 30 is shown, that is, the position where the spoiler 34 is blocked and maintained by the protrusion 122 of the inner pot. Specifically, the spoiler 34 is configured so that its two ends are blocked by a protrusion 122 respectively. In other words, the spoiler 34 is configured to include two wings extending in the radial direction and 180 degrees to each other. At the same time, it can be seen that the length and shape of the stirring blade 32 are configured so that it will not contact the protrusion 122 during the rotation process.

[0040] Figure 3 The various components of the stirring assembly 30 in this embodiment are further shown. Figure 3As shown, the spoiler 34 includes an axial mounting section 341 and two spoiler blades 38, and the overall shape is similar to the letter "M", or a ram's horn shape. The outer wall of the axial mounting section 341 is provided with an annular groove 342. The spoiler 34 is mounted to the top 320 of the mixing blade 32 through the axial mounting section 341, and the mounting enables the spoiler 34 to rotate around the axis relative to the mixing blade 32. In this embodiment, this is achieved with the aid of an axial stopper 36. Figure 3 As shown, the axial limiting member 36 includes a sleeve 361 fixed to the top 320 of the stirring blade 32 and a limiting ring 362 installed in the annular groove 342 of the axial mounting section 341 , and the sleeve 361 is sleeved outside the axial mounting section 341 and the limiting ring 362 .

[0041] also, Figure 3 A drive shaft assembly 40 is also shown. It should be understood that the drive shaft assembly 40 is sealedly mounted in the bottom through hole of the inner pot 12 and is connected to the drive device 14 disposed in the pot body 10 to transmit the power provided by the drive device 14 to the stirring assembly 30 mounted on the drive shaft assembly 40. The stirring assembly 30 is preferably fastened to the drive shaft in a detachable manner, such as by an interference fit.

[0042] Figure 4 The details of the stirring blade 32 and the shaft sleeve 361 are further shown, wherein the shaft sleeve 361 is shown in a flipped three-dimensional view to more clearly show its internal structure. Figure 4 As shown, the stirring blade 32 includes a blade holder 322 for mounting on the drive shaft assembly 40 and a stirring blade 324 fixed to the blade holder. In this embodiment, the stirring blade 324 has only a stirring function but not a cutting function. The top 320 of the stirring blade 32 is provided with an axial protrusion 323 located in the center and two arc-shaped baffles 325 surrounding the axial protrusion 323. Figure 5 It can be seen that in this embodiment, a hollow section is provided at the bottom of the axial mounting section 341, which is sleeved on the axial protrusion 323, and the arc-shaped baffle 325 provides radial positioning for the axial mounting section 341. At the same time, an L-shaped groove 321 is also provided on the outside of each arc-shaped baffle 325, including an upper baffle and a side baffle. A retaining rib 363 is provided at the corresponding position of the inner side wall of the sleeve 361. In this embodiment, there are two L-shaped grooves 321 and two retaining ribs 363, and their respective positions are radially opposite. In addition, a return edge 365 extending radially inward is also provided at the top of the sleeve 361.

[0043] In order to rotatably mount the spoiler 34 to the top of the mixing blade 32, firstly, the limiting ring 362 is placed in the sleeve 361 and the two are inserted together from the bottom of the axial mounting section 341 until the limiting ring 362 is stuck in the annular groove 342. Then, the bottom hollow section of the axial mounting section 341 is sleeved on the axial protrusion 323 and is located inside the arc-shaped baffle 325, and at the same time, the sleeve 361 is also located outside the arc-shaped baffle 325. At this time, the sleeve 361 is rotated so that its retaining rib 363 is inserted into the L-shaped slot 321, thereby fixing the sleeve 361 to the top 320 of the mixing blade 32 in both the axial and circumferential directions. It can be understood that this fixing structure only limits the displacement of the spoiler 34 in the axial and radial directions, but allows the spoiler 34 and the mixing blade 32 to rotate around the axis relative to each other. At the same time, this structure also makes it easy to remove the spoiler 34 from the mixing blade 32, and the structure is simple and easy to clean.

[0044] Figure 5 The edge of the inner pot 12 Figure 2 The cross-sectional view of the middle AA plane passes through two inner pot protrusions 122 that are radially opposite to each other. The inner pot 12 includes a side wall 121 and a bottom wall 123. The side wall 121 has a nearly vertical cylindrical section located below the pot mouth and an arc section connecting the cylindrical section and the bottom wall 123. Figure 5 As shown, in this embodiment, the protrusion 122 is located at the upper end of the arc segment in the vertical direction. On the one hand, the protrusion is arranged at a position where the inner pot has a larger diameter, which allows the stirring blade 324 to have a larger radial length, so that the stirring is more sufficient; on the other hand, the protrusion is arranged at a position where the inner pot is lower in height, which allows the spoiler 34 to have a larger size in height, so that the effective spoiler area is larger.

[0045] Figure 5 It can be seen from the figure that the spoiler 34 includes two spoiler blades 38, each of which includes a first section 381 extending upward and outward from the axial mounting section 341 and a second section 382 extending downward and almost vertically from the vertex 380 of the first section 381. When the bottom end of the second section 382 is blocked by the protrusion 122 of the inner pot 12 and maintained in the working position (i.e. Figure 2 The height and thickness combination formed by the two will cause the food in the inner pot 12 to be turned over on the inner side of the pot when it moves to the position of the protrusion 122. According to a preferred embodiment of the present invention, the distance H2 between the vertex 380 of the first section and the bottom wall 123 is at least half of the inner pot height H1. This ensures that the lower part of the food being stirred in the pot can pass under the spoiler blades, while the upper part of the food is driven to move and stirred by the spoiler blades due to the relative movement.

[0046] The cooking device according to the present invention operates as follows: the stirring assembly 30 is mounted on the drive shaft assembly 40, and the drive shaft assembly 40 rotates under the drive of the driving device 14, thereby driving the stirring blade 32 to rotate around the axis R. When the stirring assembly 30 is installed, the spoiler 34 can be directly installed to the working position, that is, the position blocked by the inner pot protrusion 122. If the spoiler 34 is not installed in place, it will still rotate to its working position due to the friction between it and the stirring blade 32 or the driving of the rotating food. When the spoiler 34 contacts the inner pot protrusion 122 and is maintained in the working position, because the connection method of the spoiler 34 and the stirring blade 32 does not limit the relative rotation between the two, and the stirring blade 32 is also arranged not to touch the inner pot protrusion 122, the stirring blade 32 still continues to rotate under the drive of the drive shaft assembly 40. Thus, the stirring blade 32 pushes the food in the pot to move during the rotation around the axis, and the lower part of the food can pass under the spoiler blade 38, while the upper part of the food is driven to move and is stirred by the first section 381 of the spoiler blade due to the relative movement. When the food moves to the spoiler 34, it will be blocked by the spoiler 34 and thus turned over, thereby ensuring that the food is heated evenly and does not stick to the pot.
