[0031] Please refer to Figure 1 , the present application embodiment proposes a cooking equipment 10, which can cook food. The type of cooking equipment 10 can be various, for example, the cooking equipment 10 can be a pressure cooker; for another example, the cooking equipment 10 can be an electric rice cooker. In the following embodiments, the cooking equipment 10 is mainly described as a pressure cooker, and the implementation of the cooking equipment 10 as an electric rice cooker can be referred to.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 , the cooking equipment 10 can include a shell 100, an outer pot 200 and a heat insulating piece 300, the shell 100 can include a shell 110 and a base 120 connected, the side of the base 120 away from the shell 110 is provided with a limiting structure 123 (as shown in Figure 8 ), the limiting structure 123 and the base 120 jointly constitute a limiting space 124 (as shown in Figure 8As shown in the drawings, the base 120 is provided with a base screw hole 122 and a limiting hole 121 which are communicated with the limiting space 124; the outer pot 200 is arranged in the shell 110, and the outer pot 200 is provided with a positioning hole 210; the heat insulation piece 300 is offset from the center position of the base 120, and the heat insulation piece 300 comprises a main body part 340, an abutting part 350 connected to the main body part 340, a positioning column 310 and a limiting protrusion 320, the main body part 340 is arranged in the base screw hole 122, the abutting part 350 is limited in the limiting space 124, the positioning column 310 is inserted and matched with the positioning hole 210, and the limiting protrusion 320 is limited and matched with the limiting hole 121, so as to limit the movement of the heat insulation piece 300 relative to the base 120 and limit the movement of the base 120 relative to the outer pot 200.

[0033] Therefore, compared with the cooking equipment in the related art, the cooking equipment 10 of the present application is provided with the positioning column 310 of the heat insulation piece 300 and the positioning hole 210 of the outer pot 200 which are inserted and matched, and the limiting protrusion 320 of the heat insulation piece 300 and the limiting hole 121 of the base 120 which are limited and matched, so as to limit the movement of the heat insulation piece 300 relative to the base 120 and limit the movement of the base 120 relative to the outer pot 200, and the heat insulation piece 300 and the base 120 and the outer pot 200 are all constrained, so that the heat insulation piece 300 can be pre-positioned during the assembly of the cooking equipment 10 (the base 120, the heat insulation piece 300 and the outer pot 200 are assembled by automatic screw locking), which helps to reduce the risk of mispositioning of the base screw hole 122 of the base 120 and the outer pot screw hole 220 (as shown in the drawings) of the outer pot 200, so as to reduce the additional manpower for manually adjusting the position of the base 120, and thus improve the production efficiency of the cooking equipment 10 and reduce the assembly cost. Figure 8 Figure 4 Therefore, compared with the cooking equipment in the related art, the cooking equipment 10 of the present application is provided with the positioning column 310 of the heat insulation piece 300 and the positioning hole 210 of the outer pot 200 which are inserted and matched, and the limiting protrusion 320 of the heat insulation piece 300 and the limiting hole 121 of the base 120 which are limited and matched, so as to limit the movement of the heat insulation piece 300 relative to the base 120 and limit the movement of the base 120 relative to the outer pot 200, and the heat insulation piece 300 and the base 120 and the outer pot 200 are all constrained, so that the heat insulation piece 300 can be pre-positioned during the assembly of the cooking equipment 10 (the base 120, the heat insulation piece 300 and the outer pot 200 are assembled by automatic screw locking), which helps to reduce the risk of mispositioning of the base screw hole 122 of the base 120 and the outer pot screw hole 220 (as shown in the drawings) of the outer pot 200, so as to reduce the additional manpower for manually adjusting the position of the base 120, and thus improve the production efficiency of the cooking equipment 10 and reduce the assembly cost.

[0034] In addition, the main body part 340 is arranged in the base screw hole 122, so that the heat insulation piece 300 is compactly matched with the base screw hole 122, thereby making the overall structure of the cooking equipment 10 more compact. Moreover, the abutting part 350 is limited in the limiting space 124, so that the heat insulation piece 300 is not easy to be separated from the base 120, thereby improving the stability and reliability of the assembly of the heat insulation piece 300 and the base 120.

[0035] Please refer to Figure 1 and Figure 2 , the shell 100 is a protective structure of the cooking equipment 10, which can prevent external dust, moisture or other pollutants from entering the inside of the cooking equipment 10, thereby protecting the internal components of the cooking equipment 10 from being contaminated or damaged.

[0036] ​The shell 100 can be made of hard plastic, which helps to provide support for the entire cooking device 10, so that the cooking device 10 is not easy to deform or damage during transportation or use.

[0037] The shell 110 can be arranged around the outer periphery of the outer pot 200, which can prevent the user from directly contacting the outer pot 200 from the outside of the cooking device 10, thereby avoiding scalding the user by the outer pot 200. The shell 110 can be connected with the outer pot 200 by screw connection or buckle connection.

[0038] When the cooking device 10 is in use, the base 120 is generally arranged at the bottom of the outer pot 200 to support the outer pot 200 and other structures. When the cooking device 10 is in an assembled state, the base 120 is generally placed above the bottom of the outer pot 200 and abuts against the shell 110, and then the base screw hole 330 of the base 120 is accurately aligned with the outer pot screw hole 220 of the outer pot 200, and finally the base 120 and the outer pot 200 are screw-connected by automatic screw locking.

[0039] The outer pot 200, as the main frame of the cooking device 10, can provide good support, so that the cooking device 10 will not deform or be damaged during use. The outer pot 200 can be made of materials with good heat conduction performance, such as stainless steel or aluminum alloy, so that the outer pot 200 has good heat conduction performance and strength.

[0040] Since high temperature is generated during the use of the cooking device 10, the outer pot 200 needs to have good high-temperature resistance, so that the outer pot 200 can work in a high-temperature environment for a long time.

[0041] The cooking device 10 can also include an inner pot (not shown in the figure), which can be installed in the outer pot 200. The inner pot can contain food. The inner pot can be made of materials such as stainless steel or aluminum alloy, so that the inner pot has sufficient strength and pressure resistance, so that the inner pot will not leak or burst in a high-pressure environment.

[0042] A heating element (not shown in the figure) can also be arranged between the inner pot and the outer pot 200. The heating element can be an electric heating tube. The heating element can be made of stainless steel or aluminum alloy. An insulating layer can be arranged on the surface of the heating element to avoid short circuit of the cooking device 10. The heating element can be connected to an external power source. When current passes through the heating element, the heating element generates heat. The heating element can transfer the heat to the inner pot to cook the food in the inner pot.

[0043] Please refer to Figures 4 to 6The heat insulation member 300 can be a heat insulation pad or a heat insulation block, etc. The heat insulation member 300 can avoid the direct contact between the base 120 and the outer pot 200, thereby helping to reduce the heat transferred from the outer pot 200 to the base 120, and further helping to reduce the heat loss of the outer pot 200, and helping to avoid the user from being scalded by the base 120 due to the excessively high temperature.

[0044] The heat insulation member 300 can be made of ceramic fiber, glass fiber or polyamide, etc., thereby making the heat insulation member 300 have good heat insulation performance, high temperature resistance and certain mechanical strength.

[0045] The overall shape of the heat insulation member 300 can be approximately cylindrical, thereby making the volume of the heat insulation member 300 small, and further helping to reduce the manufacturing cost of the heat insulation member 300. In other embodiments, the overall shape of the heat insulation member 300 can be approximately cuboid.

[0046] The main body 340 can be provided with a heat insulation member screw hole 330, which can penetrate the main body 340 along the axial direction of the main body 340. When the cooking device 10 is in the assembled state, the heat insulation member screw hole 330 can be aligned with the outer pot screw hole 220, so that the base screw hole 330, the heat insulation member screw hole 330 and the outer pot screw hole 220 are accurately aligned, thereby helping to automatically assemble the screw locking.

[0047] The number of heat insulation members 300 can be multiple, and the multiple heat insulation members 300 are arranged between the base 120 and the outer pot 200, and the adjacent two heat insulation members 300 are arranged at intervals.

[0048] Please refer to Figure 1 and Figure 4 In some embodiments, the heat insulation member 300 deviates from the center position of the base 120, and the center position is the vicinity of the axis of the base 120. That is, the axis of the heat insulation member 300 does not coincide with the axis of the base 120. The positioning column 310 and the positioning hole 210 are inserted and matched. In this way, the positioning column 310 of the heat insulation member 300 and the positioning hole 210 of the outer pot 200 are matched in the form of insertion, so that the heat insulation member 300 can be quickly inserted and matched with the outer pot 200.

[0049] In addition, due to the insertion of the positioning column 310 of the heat insulation member 300 and the positioning hole 210 of the outer pot 200, the assembly of the heat insulation member 300 and the outer pot 200 is more convenient, without the need for other complex tools.

[0050] Moreover, the heat insulation piece 300 is arranged at a position deviated from the center of the base 120, and the positioning column 310 of the heat insulation piece 300 is inserted into the positioning hole 210 of the outer pot 200, so that the heat insulation piece 300 and the outer pot 200 are connected in position, thereby restricting the heat insulation piece 300 and the outer pot 200, and thus helping to reduce the risk of rotation between the heat insulation piece 300 and the outer pot 200.

[0051] Please refer to Figure 4 In some embodiments, the outer pot 200 is provided with an outer pot screw hole 220, which is arranged opposite to the base screw hole 122. The outer pot screw hole 220 and the positioning hole 210 are independently arranged, that is, the outer pot screw hole 220 and the positioning hole 210 are arranged at intervals, and each of the outer pot screw hole 220 and the positioning hole 210 has a complete inner wall surface, so that the outer pot screw hole 220 and the positioning hole 210 do not affect each other, thereby helping to improve the stability and reliability of the overall structure of the outer pot 200.

[0052] The length of the positioning column 310 can be greater than the depth of the positioning hole 210. That is, the positioning hole 210 is a through hole, and the positioning hole 210 can pass through the opposite sides of the outer pot 200. When the positioning column 310 is inserted into the positioning hole 210, the positioning column 310 is arranged in the positioning hole 210, and the end of the positioning column 310 away from the base 120 is located in the outer pot 200. In this way, when the cooking device 10 encounters accidental collision or impact during assembly, the wall thickness of the outer pot 200 can block the positioning column 310 due to the longer length of the positioning column 310, so that the positioning column 310 is not easy to be separated from the positioning hole 210, thereby helping to reduce the risk of loosening or separation of the positioning column 310 and the positioning hole 210 due to accidental collision or other external force, and thus helping to improve the stability and reliability of the insertion and cooperation of the positioning column 310 and the positioning hole 210.

[0053] In addition, the longer positioning column 310 has better anti-vibration performance. When the cooking device 10 encounters accidental collision or impact during assembly, the longer positioning column 310 can better absorb and offset vibration, reducing the possibility of loosening between the positioning column 310 and the positioning hole 210.

[0054] Please refer to Figure 5 and Figure 6The positioning column 310 is connected to the outer periphery of the heat insulation member 300 and extends along the axial direction of the heat insulation member 300. In this way, the positioning column 310 extends from the outer periphery of the heat insulation member 300 to the end of the heat insulation member 300 along the axial direction of the heat insulation member 300, forming a structure that is easy to insert and pull out, thereby facilitating the easy insertion and pulling out of the positioning column 310 and the positioning hole 210 and rapid alignment. In addition, the positioning column 310 can also serve as a structure similar to a reinforcing rib to improve the overall rigidity and bending strength of the heat insulation member 300, so that the heat insulation member 300 is not easily deformed when subjected to external external force or impact. Moreover, the presence of the positioning column 310 can help to disperse the stress applied to the heat insulation member 300, avoiding local stress concentration of the heat insulation member 300 and causing damage.

[0055] Please refer to Figures 4 to 6 The positioning column 310 protrudes from the end of the heat insulation member 300 along the axial direction of the heat insulation member 300 in the direction of the outer pot 200, and the outer diameter of the end of the positioning column 310 gradually decreases as it approaches the end of the outer pot 200. The overall shape of the end of the positioning column 310 can be generally conical. The conical design of the end of the positioning column 310 can serve as an automatic alignment function. When the positioning column 310 approaches the positioning hole 210, even if the initial position of the positioning column 310 and the positioning hole 210 is slightly offset, the conical end of the positioning column 310 can guide the positioning column 310 to quickly align and enter the positioning hole 210, thereby facilitating the reduction of the difficulty of manual alignment of the positioning column 310 and the positioning hole 210, and facilitating the more rapid and convenient insertion of the positioning column 310 into the positioning hole 210.

[0056] The main body portion 340 is provided with an abutting plane 341 abutting against the outer pot 200 on the side facing the outer pot 200, and the positioning column 310 protrudes from the edge of the abutting plane 341 to the abutting plane 341, so that there is no separation gap between the positioning column 310 and the main body portion 340, thereby facilitating the guarantee of the overall strength of the heat insulation member 300, and also facilitating the processing of the heat insulation member 300. In addition, the abutting plane 341 abuts against the outer pot 200, thereby facilitating the increase of the contact area between the heat insulation member 300 and the outer pot 200, and thereby facilitating the improvement of the stability of the connection between the heat insulation member 300 and the outer pot 200.

[0057] Please refer to Figure 5 , Figure 7 and Figure 8In the assembling process of the cooking device 10, the limiting cooperation between the limiting hole 121 and the limiting protrusion 320 enables the heat insulation member 300 to be accurately installed at the predetermined position of the base 120, so that the position of the heat insulation member 300 relative to the base 120 will not change, thereby providing a reference basis for the accurate alignment of the positioning column 310 and the positioning hole 210 subsequently. When assembling the heat insulation member 300 with the outer pot 200, the accurate alignment of the positioning column 310 and the positioning hole 210 can be ensured through the known reference basis.

[0058] Moreover, since the accurate position of the positioning column 310 has been ensured by the limiting cooperation between the heat insulation member 300 and the base 120, when assembling the heat insulation member 300 with the outer pot 200, it is only necessary to focus on the alignment of the positioning column 310 and the positioning hole 210, without the need to adjust the position of the heat insulation member 300 relative to the base 120, thereby helping to improve the assembling efficiency of the cooking device 10.

[0059] In some embodiments, the limiting protrusion 320 can be a limiting column or a limiting protrusion, and the shape of the limiting protrusion 320 can be adapted to the shape of the limiting hole 121, so as to facilitate the limiting cooperation between the limiting protrusion 320 and the limiting hole 121.

[0060] Please refer to Figure 5 and Figure 8 In some embodiments, the overall cross-sectional outer contour of the limiting hole 121 and the base screw hole 122 is non-circular, and the overall cross-sectional outer contour of the main body portion 340 and the limiting protrusion 320 is non-circular. The limiting hole 121 can extend along the axial direction of the base screw hole 122. The overall cross-sectional outer contour of the limiting hole 121 and the base screw hole 122 can be in the shape of an ellipse or a triangle, and the overall cross-sectional outer contour of the main body portion 340 and the limiting protrusion 320 can also be in the shape of an ellipse or a triangle. The overall cross-sectional outer contour of the limiting hole 121 and the base screw hole 122 can be adapted to the overall cross-sectional outer contour of the main body portion 340 and the limiting protrusion 320. In this way, it is helpful to limit the rotation of the heat insulation member 300 relative to the base 120, thereby reducing the risk of rotation of the heat insulation member 300 under the action of external forces such as accidental collision.

[0061] In some embodiments, the limiting protrusion 320 is connected to the side surface of the main body portion and extends along the axial direction of the main body portion. In this case, the side surface of the limiting protrusion 320 can be connected to the side surface of the main body portion 340. In this way, the limiting protrusion 320 can also serve as a structure similar to a reinforcing rib to improve the overall rigidity and bending strength of the heat insulation piece 300, so that the heat insulation piece 300 is less likely to be deformed when subjected to external force or impact. In addition, due to the presence of the limiting protrusion 320, when the heat insulation piece 300 is subjected to external pressure, the limiting protrusion 320 can disperse the pressure to the base 120, thereby helping to reduce the risk of local stress concentration of the heat insulation piece 300 leading to damage.

[0062] Referring to Figure 6 , Figure 9 and Figure 10 , in some embodiments, the abutting portion 350 can be located at the end of the main body portion 340, and the main body portion 340 extends along the radial direction of the main body portion 340 and is arranged around the circumference of the main body portion 340. The limiting structure 123 can be a spring column embedded in the base 120, such as a rubber spring column or a silica gel spring column, etc. One end of the limiting structure 123 can be embedded in the base 120, and the other end of the limiting structure 123 can abut against the abutting portion 350, thereby limiting the heat insulation piece 300, so that the heat insulation piece 300 is less likely to fall off from the base screw hole 122.

[0063] The limiting structure 123 can also be a buckle structure. Along the axial direction of the main body portion 340, the buckle structure and the base 120 jointly clamp the abutting portion 350 to limit the movement of the heat insulation piece 300 along the axial direction of the base screw hole 122, so that the heat insulation piece 300 is less likely to fall off from the base screw hole 122.

[0064] Referring to Figure 4 , Figure 5 and Figure 10 , in some embodiments, the buckle structure can include an elastic hook located on the side of the base 120 away from the outer pot 200. The hook portion of the elastic hook and the base 120 can jointly clamp the abutting portion 350 along the axial direction of the base screw hole 122, thereby helping to limit the movement of the heat insulation piece 300 along the axial direction of the base screw hole 122.

[0065] The number of elastic hooks can be multiple, and the multiple elastic hooks can be arranged in sequence and at intervals along the edge of the abutting portion 350. The multiple elastic hooks can limit the movement of the heat insulation piece 300 along the radial direction of the base screw hole 122.

[0066] In some embodiments, the heat insulation piece 300, the positioning column 310 and the limiting protrusion 320 can be integrally formed, thereby helping to reduce the assembly process between the heat insulation piece 300, the positioning column 310 and the limiting protrusion 320, and thereby helping to improve the assembly efficiency of the cooking equipment 10.

[0067] Based on the above embodiment, before the outer pot 200, the heat insulation piece 300 and the base 120 of the cooking device 10 are automatically screwed by the LCIM (Low-Cost Intelligent Manufacturing) production line, the outer pot 200 needs to be assembled with the shell 110 and clamped by the clamp. In the process of manually assembling the cooking device 10, the heat insulation piece 300 is assembled on the base 120, the limiting convex part 320 is limited with the limiting hole 121, the abutting part 341 is clamped by the base 120 and the limiting structure 123, so as to limit the movement of the heat insulation piece 300 relative to the base 120, then the positioning column 310 of the heat insulation piece 300 is inserted and matched with the positioning hole 210 of the outer pot 200, the heat insulation piece 300 and the outer pot 200 are pre-positioned, so that the base screw hole 122, the heat insulation piece screw hole 330 and the outer pot screw hole 220 are accurately aligned, thereby meeting the production requirement of the LCIM production line for automatically screwing the outer pot 200, the heat insulation piece 300 and the base 120 of the cooking device 10, and further helping to reduce the process of manually adjusting the positions of the outer pot 200, the heat insulation piece 300 and the base 120.
