Description

Technical Field

[0001] This invention relates to the field of kitchen equipment technology, and in particular to cooking equipment. Background Technology

[0002] Cooking appliances such as steam ovens, regular ovens, and steam ovens primarily rely on heating elements to create a high-temperature environment within the cooking cavity to cook food. Especially with ovens, the cooking cavity is generally enclosed, with the heating element located outside the inner chamber. The heat generated by the heating element must be transferred to the cooking cavity through heat conduction within the inner chamber. This results in food being cooked at different rates in different parts, affecting its color and texture. Summary of the Invention

[0003] This invention addresses the problem of uneven cooking of different parts of food when cooked by cooking equipment. It proposes a cooking device that ensures more even heating of all parts of the food, thereby guaranteeing a more consistent cooking degree for all parts of the food.

[0004] A cooking device includes an inner pot, a heating element, and a driving element. The inner pot forms a cooking cavity, the heating element is located outside the inner pot and in contact with the inner pot, and the driving element is disposed on the inner pot and connected to the heating element for driving the heating element to move outside the inner pot.

[0005] The above solution provides a cooking device in which a heating element located outside the inner pot generates heat during operation. This heat is conducted to the cooking cavity through the inner pot in contact with it. The driving assembly moves the heating element outside the inner pot, allowing it to contact different parts of the inner pot. This ensures that all parts of the inner pot participate in the heat conduction process, improving the uniformity of heat distribution within the cooking cavity. Ultimately, this results in food processed within the cooking cavity being heated more evenly across all parts, achieving a more consistent cooking temperature.

[0006] In one embodiment, the heating element is attached to the outer side of the inner liner, and the driving element is used to drive the heating element to move on the outer side of the inner liner.

[0039] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 7 As shown, in one embodiment, a cooking device 10 is provided, including an inner pot 11, which forms a cooking cavity 111. During cooking, food is placed in the cooking cavity 111, specifically, as shown... Figure 1 and Figure 4 As shown, a food rack 15 can be installed in the cooking cavity 111, and food is placed on the food rack 15 during the cooking process. The cooking device 10 can be a kitchen appliance that requires heating, such as a steam oven, oven, or steam oven.

[0041] Furthermore, such as Figures 1 to 3 As shown, the cooking device 10 also includes a heating element 13 and a driving element 12. The heating element 13 is located outside the inner pot 11 and is in contact with the inner pot 11. The driving element 12 is disposed on the inner pot 11 and is connected to the heating element 13, and is used to drive the heating element 13 to move outside the inner pot 11.

[0042] The cooking device 10 provided by the above solution includes a heating element 131 located outside the inner pot 11. When in operation, the heating element 131 generates heat, which is conducted to the cooking cavity 111 through the inner pot 11 in contact with it. The driving assembly 12 drives the heating element 131 to move outside the inner pot 11, allowing it to contact different parts of the inner pot 11. This ensures that different parts of the inner pot 11 participate in the heat conduction process, thereby improving the uniformity of heat distribution within the cooking cavity 111. Ultimately, this results in food processed in the cooking cavity 111 being heated more evenly across all parts, achieving a more consistent cooking temperature.

[0043] Specifically, after the driving component 12 drives the heating element 131 to move, the position on the inner pot 11 that is in direct contact with the heating element 131 changes, thereby changing the temperature of the inner pot 11, which in turn makes the temperature distribution in the cooking cavity 111 more uniform and ensures that the cooked food is cooked to a more consistent degree.

[0044] Furthermore, such as Figures 1 to 3 As shown, in one embodiment, the heating element 13 is attached to the outer surface of the inner liner 11, and the driving component 12 is used to drive the heating element 13 to move on the outer surface of the inner liner 11. In other words, under the driving action of the driving component 12, the heating element 13 can always remain attached to the inner liner 11 during the movement, so that the heat transfer process can continue.

[0045] Furthermore, such as Figure 5 As shown, in one embodiment, the heating component 13 and the driving component 12 constitute a dynamic heating unit. There are two dynamic heating units, one of which is located outside the left side wall 112 of the inner liner 11, and the other is located outside the right side wall 113 of the inner liner 11.

[0046] The dynamic heating unit is provided on the outside of the left side wall 112 and the right side wall 113 of the inner pot 11, which further makes the heat distribution in the cooking cavity 111 more uniform.

[0047] Furthermore, in one embodiment, such as Figures 1 to 7 As shown, a fixed heating device 16 is provided on the top wall 114 and the bottom wall 115 of the inner pot 11. The fixed heating device 16 is fixed in position relative to the inner pot 11, providing stable heat to the cooking cavity 111.

[0048] More specifically, the direction in which the heating element 13 moves can be the front-to-back direction of the inner liner 11. For example... Figure 1 As shown, the opening of the cooking cavity 111 faces forward. During use, there is a large temperature difference between the front and rear parts of the cooking cavity 111. The heating element 13 moves in the front-back direction, which can effectively improve the uniformity of temperature distribution in the cooking cavity 111.

[0049] Furthermore, in one embodiment, such as Figures 1 to 3 ,as well as Figure 6 and Figure 7 As shown, the drive assembly 12 is located outside the inner liner 11. A guide groove 1121 is provided on the outer side of the inner liner 11 at a position corresponding to the drive assembly 12, and a support protrusion 1124 for placing the food rack 15 is formed on the inner side of the inner liner 11.

[0050] Specifically, such as Figure 4 As shown, when the cooking device 10 includes two dynamic heating units, the left side wall 112 and the right side wall 113 of the inner pot 11 are provided with the guide groove 1121, so that the inner side of the left side wall 112 and the inner side of the right side wall 113 of the inner pot 11 both have the support protrusion 1124, and the two ends of the food rack 15 are respectively supported on the two support protrusions 1124.

[0051] Furthermore, such as Figures 1 to 3 As shown, the driving component 12 is installed in the guide groove 1121 and is used to drive the heating component 13 to move along the guide direction of the guide groove 1121. When the driving component 12 is in operation, it moves along the guide groove 1121, thereby driving the heating component 13 connected to it to move along the guide direction of the guide groove 1121.

[0052] More specifically, the drive assembly 12 can be a telescopic drive component such as a cylinder with telescopic function, or such as... Figures 1 to 7 As shown, the drive assembly 12 includes a drive motor 121 and a gear 122. The gear 122 is connected to the rotating shaft 1211 of the drive motor 121. When the drive motor 121 is running, the gear 122 rotates.

[0053] Specifically, in one embodiment, such as Figure 6 , Figure 7 and Figure 13 As shown, the drive assembly 12 includes a drive motor 121, a gear 122, and a connecting support 123. The connecting support 123 connects the drive motor 121 and the heating assembly 13. The gear 122 is connected to the rotating shaft 1211 of the drive motor 121. Figure 8 and Figure 9As shown, the side wall of the guide groove 1121 is provided with a tooth 1123 that matches the gear 122. The gear 122 is installed in the guide groove 1121 and the gear 122 meshes with the tooth 1123.

[0054] Therefore, when the drive motor 121 rotates, the gear 122 rotates, and the drive motor 121, gear 122, and connecting support 123 all move along the guiding direction of the guide groove 1121. The heating element 13 connected to the connecting support 123 also moves accordingly. By adjusting the direction of rotation of the drive motor 121, the moving direction of the heating element 13 can be changed.

[0055] Specifically, such as Figure 15 and Figure 16 As shown, the cross-section of the shaft 1211 of the drive motor 121 is polygonal, and the hole in the gear 122 for insertion of the shaft 1211 is a matching polygonal hole. Therefore, when the shaft 1211 rotates, the gear 122 can rotate accordingly.

[0056] Furthermore, such as Figures 1 to 3 ,as well as Figure 6 and Figure 7 As shown, in one embodiment, the guide groove 1121 is arranged along the front-rear direction of the inner liner 11. Thus, when the gear 122 moves within the guide groove 1121, the heating element 13 moves along the guiding direction of the guide groove 1121.

[0057] Furthermore, such as Figures 1 to 3 ,as well as Figure 6 and Figure 7 As shown, the heating element 13 includes two heating elements 131, and the driving element 12 is used to drive the two heating elements 131 to move. The two heating elements 131 are located on the upper and lower sides of the guide groove 1121, respectively, and both heating elements 131 are connected to the connecting support member 123. When the connecting support member 123 moves, the two heating elements 131 follow and move along the guiding direction of the guide groove 1121.

[0058] Specifically, such as Figures 1 to 3 As shown, the heating element 131 is clamped between the inner liner 11 and the connecting support 123. Figure 13 and Figure 18 As shown, the heating element 131 has a connecting hole 1311 on the side facing away from the inner liner 11, and the connecting support 123 has a through hole at the position corresponding to the connecting hole 1311. The connector can be installed into the connecting hole 1311 by passing through the through hole, thereby connecting the heating element 131 and the connecting support 123 together.

[0059] Furthermore, in one embodiment, the cooking cavity 111 is provided with a plurality of temperature sensors, which are arranged sequentially at intervals in the front-rear direction of the inner pot 11. This allows for the detection of the temperature of various parts within the cooking cavity 111, and the operation of the drive assembly 12 is controlled based on the detection results of the temperature sensors, thereby adjusting the position of the heating assembly 13.

[0060] More specifically, in one embodiment, such as Figures 5 to 7 As shown, a control unit 17 is provided on the rear wall 116 of the inner liner 11. The control unit 17 is electrically connected to both the temperature detection element and the drive motor 121. The control unit 17 controls the drive motor 121 to operate based on the temperature of each part detected by the multiple temperature detection elements, thereby causing the gear 122 to rotate and adjusting the position of the heating element 131.

[0061] Furthermore, in one embodiment, such as Figures 1 to 8 As shown, the outer surface of the inner liner 11 is also provided with a limiting guide groove 1122. The guiding direction of the limiting guide groove 1122 is consistent with the guiding direction of the guide groove 1121, and the limiting guide groove 1122 and the guide groove 1121 are arranged at intervals. Figures 1 to 3 As shown, the connecting support 123 extends to the location of the limiting guide groove 1122. Figure 6 , Figure 7 and Figure 13 As shown, the connecting support 123 is provided with a guide wheel 124. The guide wheel 124 is confined in the limiting guide groove 1122 and is movable in the limiting guide groove 1122. When the driving assembly 12 operates to move the connecting support 123, the guide wheel 124 moves in the limiting guide groove 1122.

[0062] Because the guide wheel 124 is confined within the limiting guide groove 1122, the connecting support 123 connected to the guide wheel 124 will not detach from the inner liner 11, and consequently, the drive motor 121, gear 122, and heating element 13 will not detach from the inner liner 11. This ensures that the gear 122 is reliably positioned within the guide groove 1121. The heating element 13 is clamped between the inner liner 11 and the connecting support 123, ensuring reliable contact between the heating element 13 and the inner liner 11.

[0063] Specifically, such as Figure 6 , Figure 7 and Figure 17As shown, the guide wheel 124 includes a roller body 1241 and a bearing 1242 sleeved on the roller body 1241. The roller body 1241 is connected to the connecting support 123, and the bearing 1242 is located in the limiting guide groove 1122. When the guide wheel 124 moves in the limiting guide groove 1122, the bearing 1242 can rotate relative to the roller body 1241.

[0064] Furthermore, in one embodiment, such as Figure 6 and Figure 7 As shown, the cooking device 10 also includes a limiting frame 14 formed by folding a rod in half. The folded rod forms a guide gap 142 with one open end. The limiting frame 14 is connected to the inner pot 11. The guide gap 142 is arranged along the guiding direction of the limiting guide groove 1122, and the guide gap 142 is located at the opening of the limiting guide groove 1122. The width of the guide gap 142 is smaller than the outer diameter of the guide wheel 124, thereby the limiting frame 14 limits the guide wheel 124 within the limiting guide groove 1122.

[0065] During the assembly process, such as Figure 13 As shown, this occurs after the drive assembly 12 and the heating assembly 13 are assembled. Figures 8 to 12 As shown, the limiting frame 14 is first installed on the inner liner 11, then the fixed heating device 16 and the control unit 17 are placed on the inner liner 11, and then the guide wheel 124 is installed from the opening of the limiting frame 14 into the limiting guide groove 1122. The limiting frame 14 then limits the guide wheel 124 in the limiting guide groove 1122, ensuring that the drive assembly 12 and the heating assembly 13 will not fall off the inner liner 11.

[0066] Specifically, such as Figures 1 to 3 ,as well as Figure 6 and Figure 7 As shown, in one embodiment, the fold crease of the rod is located at the folded end 141 of the limiting frame 14, and the folded end 141 is inclined towards the inner liner 11 relative to the other parts of the limiting frame 14. The folded end 141 is welded to the inner liner 11.

[0067] Thus, the limiting frame 14 can be reliably connected to the inner liner 11. At the same time, when the open end of the limiting frame 14 is subjected to a large outward pulling force, the limiting frame 14 can undergo a slight elastic deformation, which facilitates the placement of the guide wheel 124 into the limiting guide groove 1122 during the installation process.

[0068] Furthermore, such as Figures 1 to 3 ,as well as Figure 6 and Figure 7As shown, in one embodiment, the outer surface of the inner liner 11 is provided with two limiting guide grooves 1122, which are located on the upper and lower sides of the guide groove 1121, respectively. The connecting support member 123 is provided with two guide wheels 124, which are respectively positioned within the two limiting guide grooves 1122. Two limiting frames 14 are provided, each corresponding to one of the two limiting guide grooves 1122. Both ends of the connecting support member 123 are limited by the guide wheels 124, ensuring that the drive motor 121, gear 122, and heating element 13 can be reliably positioned on the inner liner 11.

[0069] Furthermore, such as Figure 10 and Figure 11 As shown, the opening formed by folding the rod is the opening of the limiting frame 14, and the openings of the two limiting frames 14 face opposite directions.

[0070] During installation, first, one guide wheel 124 on the connecting support 123 is installed into the limiting guide groove 1122. Then, the dynamic heating unit is moved so that the guide wheel 124 slides to the folded end 141 of the limiting guide groove 1122. Next, the other guide wheel 124 on the connecting support 123 is installed from the opening of another limiting frame 14 into the corresponding limiting guide groove 1122. Once the dynamic heating unit is in place, both guide wheels 124 are reliably positioned within their respective limiting guide grooves 1122.

[0071] Furthermore, such as Figure 14 and Figure 15 As shown, in one embodiment, the connecting support 123 is bent at a position corresponding to the drive motor 121 to form a latching portion 1231, the latching portion 1231 forming a clamping space 1233 with three open sides. Figure 13 As shown, the three side walls of the clamping space 1233 are perpendicular to the side walls of the inner liner 11. The drive motor 121 is clamped in the clamping space 1233, and the shaft 1211 of the drive motor 121 is perpendicular to the bottom wall 115 of the guide groove 1121. The rotation axis of the gear 122 is also perpendicular to the bottom wall 115 of the guide groove 1121. When the shaft 1211 of the drive motor 121 rotates, the gear 122 moves in the guide groove 1121.

[0072] Furthermore, such as Figure 14 and Figure 15As shown, the connecting support 123 also includes two connecting strips 1232, one connecting strip 1232 connecting the buckle part 1231 to one of the guide wheels 124, and the other connecting strip 1232 connecting the buckle part 1231 to the other guide wheel 124. Figure 13 As shown, the heating component 13 includes two heating elements 131, which are connected one-to-one with the connecting strips 1232. The heating elements 131 are clamped between the inner liner 11 and the corresponding connecting strips 1232.

[0073] When the gear 122 moves in the guide groove 1121, the drive motor 121, the buckle part 1231, the connecting bar 1232 and the heating element 131 move accordingly, so that the heating element 131 is always in contact with the inner liner 11 and the position of the heating element 131 can be adjusted.

[0074] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.
