[0015] Beneficial effects of the utility model:

[0016] The fan bracket and fan in the utility model can be assembled in advance to form a fan assembly, which is fast and does not occupy a large amount of storage space. After the fan assembly is formed, the fan assembly is assembled at the vent after the insulation ring and the middle ring are assembled, thereby preventing the fan assembly from interfering with the rotation of the insulation ring, and allowing the insulation ring to rotate relative to the middle ring. In this way, a screw buckle protrusion is provided on the top of the insulation ring, and the middle ring is provided with a screw buckle groove. By rotating the insulation ring, the screw buckle protrusion can be snapped into the screw buckle groove and fixed, so that the insulation ring and the middle ring are rotationally snap-fitted and fixed. Through the cooperation of the screw buckle protrusion and the screw buckle groove, the insulation ring can realize vertical and radial limitation and support of the middle ring, thereby avoiding vertical deformation and radial inward deformation of the middle ring, that is, indirectly enhancing the strength of the middle ring, thereby achieving the effect of effectively avoiding deformation of the middle ring.

[0017] The heat preservation ring includes a body and a flange formed by bending outward from the top of the body, the flange supports the middle ring, and the flange partially extends outward to form a screw-on protrusion. By designing the flange, the flange can form circumferential support for the middle ring, so as to further increase the contact area between the heat preservation ring and the middle ring, thereby improving the support effect on the middle ring and effectively preventing the middle ring from deforming downward; in addition, the screw-on protrusion is formed by partially extending the flange outward, which can also enhance the structural strength of the screw-on protrusion and prevent the screw-on protrusion from breaking.

[0018] The outer edge of the flange is bent downward to form a flange, and a plurality of reinforcing ribs are arranged between the inner circumference of the flange and the outer circumference of the body. Such a design can further enhance the structural strength of the flange and the turn-buckle protrusion through the arrangement of the flange and the reinforcing ribs, thereby preventing the flange and the turn-buckle protrusion from being deformed or even broken, thereby ensuring the connection reliability and support reliability between the insulation ring and the middle ring, and effectively preventing the middle ring from being deformed.

[0019] The middle ring includes a top plate located above the heat preservation ring and a protective plate extending downward from the bottom surface of the top plate. The protective plate surrounds the outside of the heat preservation ring. A clamping rib is convexly arranged on the inner side of the protective plate. The clamping rib cooperates with the lower surface of the top plate to form a screw-on slot. With such a design, the structural strength of the top plate can be enhanced by arranging the protective plate to further effectively prevent the top plate from being sunken and deformed. The clamping rib is convexly arranged on the inner side of the protective plate and cooperates with the lower surface of the top plate to form a screw-on slot, which can reduce the difficulty of molding the screw-on slot and facilitate the injection molding of the middle ring.

[0020] At least one of the clamping ribs includes an arc segment extending along the circumference of the protective plate and a limit segment connected to one end of the arc segment and extending upward, and the limit segment is connected to the bottom surface of the top plate. This design can prevent the user from over-rotating the heat preservation ring and causing the buckle protrusion to disengage from the buckle slot, thereby reducing the difficulty of assembling the heat preservation ring and the middle ring; in addition, the buckle protrusion abuts against the limit segment, which can also prompt the heat preservation ring to rotate into place, thereby further reducing the difficulty of assembly.

[0021] The middle ring is provided with a plurality of screw buckle slots, and the plurality of screw buckle slots are unevenly distributed at circumferential intervals. Such a design can avoid the wrong installation of the heat preservation ring, and ensure that after the heat preservation ring is rotated into place, the fan assembly corresponds to the air inlet on the housing.

[0022] The pot body also includes an air net, and a mounting groove is provided on the inner circumference of the insulation ring. The air net includes an air net body with a plurality of mesh holes and a mounting edge formed by bending the edge of the air net body. The mounting edge is inserted and fixed in the mounting groove so that the mesh holes are connected to the vents. With such a design, the air net and the insulation ring can be installed and fixed by simply inserting the mounting edge into the mounting groove. At the same time, disassembly and assembly are relatively simple and convenient, which is conducive to later cleaning. In addition, the design of the air net can also prevent foreign objects or reptiles from entering the insulation ring.

[0023] The outer circumference of the heat preservation ring is provided with a slot, the slot has a socket, the fan bracket is provided with a plug-in rib, and the plug-in rib is inserted into the slot through the socket. With this design, during assembly, the fan assembly can be assembled to the heat preservation ring by simply inserting the plug-in rib into the slot, thereby limiting the fan bracket except for the opposite direction of the insertion direction through the slot, making the assembly simple and convenient, and further improving the assembly efficiency of the cooking appliance.

[0024] The pot body also includes an electromagnetic wire coil installed at the bottom of the insulation ring. The electromagnetic wire coil and the insulation ring form a receiving cavity for accommodating the inner pot. The socket is open toward the electromagnetic wire coil. The electromagnetic wire coil sets a lower limit on the fan assembly to prevent the plug-in rib from falling out of the slot. In this design, the electromagnetic wire coil sets a lower limit on the fan assembly to prevent the plug-in rib from falling out of the slot, thereby improving the installation reliability of the fan bracket and the insulation ring, and there is no need to add other additional structures to prevent the plug-in rib from falling out of the slot, so the structure is also simpler.

[0025] The electromagnetic wire drum is fixed to the connecting column by fasteners. With this design, the clamping force can be generated by the fixed connection between the electromagnetic wire drum and the connecting column to clamp and fix the insulation ring between the middle ring and the electromagnetic wire drum, thereby improving the installation reliability of the insulation ring and ensuring the limiting effect of the insulation ring on the middle ring, that is, ensuring the structural strength of the middle ring and effectively preventing it from deforming.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.

[0040] Reference Figures 1 to 7 As shown, the cooking utensil in this embodiment includes a pot body, which includes a middle ring 100, an outer shell (not shown in the figure), an insulation ring 200 and a fan assembly 300. The outer shell is an annular structure surrounding the outer side of the insulation ring 200. The fan assembly 300 is arranged between the insulation ring 200 and the outer shell. The fan assembly 300 includes a fan bracket 310 and a fan 320 connected to the fan bracket 310 by screws. The middle ring 100 has a connecting column 140 extending downward, the insulation ring 200 is provided with a vent 201, the top of the insulation ring 200 is provided with a screw buckle protrusion 210, and the middle ring 100 is provided with a screw buckle groove 110. The insulation ring 200 is rotated to make the screw buckle protrusion 210 snap into the screw buckle groove 110 for fixation, and the vent 201 avoids the connecting column 140, so that the fan assembly 300 can be assembled at the vent 201 after the insulation ring 200 and the middle ring 100 are assembled.

[0041] The fan bracket 310 and the fan 320 in this embodiment can be assembled in advance to form the fan assembly 300, which is fast and does not occupy a large amount of storage space. After the fan assembly 300 is formed, the fan assembly 300 is assembled at the vent 201 after the insulation ring 200 and the middle ring 100 are assembled, thereby preventing the fan assembly 300 from interfering with the rotation of the insulation ring 200, and allowing the insulation ring 200 to rotate relative to the middle ring 100. In this way, by providing a screw buckle protrusion on the top of the insulation ring 200, the middle ring 100 is provided with a plurality of The screw-on groove 110 can be used to rotate the insulation ring 200 so that the screw-on protrusion 210 can be inserted into the screw-on groove 110 and fixed, so that the insulation ring 200 and the middle ring 100 can be rotatably connected and fixed. Through the cooperation between the screw-on protrusion 210 and the screw-on groove 110, the insulation ring 200 can realize vertical and radial limitation and support for the middle ring 100, thereby avoiding vertical and radial deformation of the middle ring 100, that is, indirectly enhancing the strength of the middle ring 100, thereby achieving the effect of effectively avoiding deformation of the middle ring 100.

[0042] Specifically, the middle ring 100 in this embodiment includes a top plate 120 located above the insulation ring 200. Figure 2 As shown, the insulation ring 200 includes a main body 220 and a flange 230 formed by bending the top of the main body 220 outward, the flange 230 is annular, and the top surface of the flange 230 is against the bottom surface of the top plate 120, so that the flange 230 supports the middle ring 100. In this way, by designing the flange, the flange 230 can form a circumferential support for the middle ring 100, so as to further increase the contact area between the insulation ring 200 and the middle ring 100, thereby improving the support effect on the middle ring 100, and effectively avoiding the top plate 120 of the middle ring from deforming downward; in addition, the turn-on protrusion 210 is formed by partially extending the flange 230 outward, which can also enhance the structural strength of the turn-on protrusion 210 and avoid the turn-on protrusion 210 from breaking.

[0043] In order to further enhance the structural strength of the flange 230 and the turn-on protrusion 210, in the present embodiment, the outer edge of the flange 230 is bent downward to form a flange 231, and a plurality of reinforcing ribs 240 are provided between the inner peripheral side of the flange 231 and the outer peripheral side of the main body 220, and the reinforcing ribs 240 are connected to the bottom surface of the flange 230. Such a design can further enhance the structural strength of the flange 230 and the turn-on protrusion 210 through the provision of the flange 231 and the reinforcing ribs 240, thereby avoiding deformation or even breakage of the flange 230 and the turn-on protrusion 210, thereby ensuring the connection reliability and support reliability between the insulation ring 200 and the middle ring 100, and effectively avoiding deformation of the middle ring 100.

[0044] In addition, if Figure 3 As shown, the middle ring 100 in this embodiment also includes a protective plate 130 extending downward from the bottom surface of the top plate 120 and integrally formed, the protective plate 130 surrounds the outside of the heat preservation ring 200, and a clamping rib 131 is convexly provided on the inner side of the protective plate 130, and the clamping rib 131 cooperates with the lower surface of the top plate 120 to form the above-mentioned screw-on clamping groove 110. With such a design, the structural strength of the top plate 120 can be enhanced by setting the protective plate 130, so as to further effectively prevent the top plate 120 from being sunken and deformed; and the clamping rib 131 is convexly provided on the inner side of the protective plate 130, and cooperates with the lower surface of the top plate 120 to form the screw-on clamping groove 110, which can reduce the molding difficulty of the screw-on clamping groove 110, so as to facilitate the injection molding of the middle ring 100.

[0045] Preferably, one of the clip ribs 131 includes an arc segment 1310 extending circumferentially along the protective plate 130 and a limit segment 1311 connected to one end of the arc segment 1310 and extending upward. The upward extension in this embodiment refers to the extension in the direction of the top surface of the top plate 120, and the limit segment 1311 is connected to the bottom surface of the top plate 120. Such a design can prevent the user from over-rotating the heat preservation ring 200, causing the turn buckle protrusion 210 to disengage from the turn buckle slot 110, thereby reducing the difficulty of assembling the heat preservation ring 200 and the middle ring 100; in addition, the heat preservation ring 200 can be prompted to rotate into place by the turn buckle protrusion 210 and the limit segment 1311, so as to further reduce the difficulty of assembly. Preferably, a reinforcing rib 132 is connected between the arc segment 1310 and the protective plate 130, so as to further enhance the structural strength of the clip rib 131 and avoid breaking.

[0046] It can be understood that in other embodiments of the utility model, all the clamping ribs include an arc segment extending circumferentially along the protective plate and a limiting segment connected to one end of the arc segment and extending upward, and the limiting segment is connected to the bottom surface of the top plate. Such a design can further enhance the circumferential limiting effect on the insulation ring.

[0047] In addition, the housing in this embodiment is provided with an air inlet corresponding to the vent 201. When the fan assembly 300 is working, it draws in cold air from the outside through the air inlet and blows it into the heat preservation ring 200 to dissipate heat from the inner pot in the heat preservation ring 200, thereby preventing the rice from sticking to the pot. In order to prevent the heat preservation ring 200 from being installed incorrectly and causing the fan assembly 300 to fail to correspond to the air inlet and need to be reworked and reinstalled, the multiple screw-on slots 110 in this embodiment are non-uniformly distributed at circumferential intervals. This design can prevent the heat preservation ring 200 from being installed incorrectly, so as to ensure that after the heat preservation ring 200 is rotated into place, the fan assembly 300 corresponds to the air inlet on the housing.

[0048] Furthermore, in order to prevent foreign matter or reptiles from entering the heat preservation ring 200 through the vent 201, the pot body in this embodiment further includes a wind net 400, such as Figure 6 As shown, the insulation ring 200 is provided with a mounting groove 250 surrounding the outside of the vent 201, and the wind net 400 includes a wind net body 410 provided with a plurality of mesh holes and a mounting edge 420 formed by bending the edge of the wind net body 410, and the mounting edge 420 is inserted and fixed in the mounting groove 250 so that the mesh holes are correspondingly connected with the vent 201. With such a design, the wind net 400 and the insulation ring 200 can be installed and fixed by simply inserting the mounting edge 420 into the mounting groove 250, and the disassembly and assembly are relatively simple and convenient, which is conducive to later cleaning; in addition, the design of the wind net 400 can also prevent foreign objects or reptiles from entering the insulation ring 200.

[0049] In order to reduce the difficulty of assembling the fan assembly 300 and the insulation ring 200, as Figure 1 and Figure 4As shown, in this embodiment, the outer circumferential side of the insulation ring 200 is provided with two mounting ears 260 that are integrally formed and circumferentially spaced, and the mounting ears 260 extend along the axial direction of the insulation ring 200. The mounting ears 260 include a first vertical section 261 connected to the body 220 and extending along the axial direction of the insulation ring 200, a second vertical section 262 formed by bending the first vertical section 261 toward the other mounting ear 260, and a connecting portion 261 and a connecting portion 262 connected to the first vertical section 261 and the second vertical section 262. The mounting ears 260 cooperate with the outer peripheral side of the body 220 to form a slot 270, and the slot 270 has a socket 271, which is open toward the side away from the top plate 120. The fan bracket 310 is provided with a plug rib 311, and the plug rib 311 is inserted into the slot 270 through the socket 271. With such a design, during assembly, the fan assembly 300 can be assembled to the insulation ring 200 by simply inserting the plug rib 311 into the slot 270, so that the fan bracket 310 can be limited in the direction other than the opposite direction of the insertion direction through the slot 270, that is, the upper limit, circumferential limit and radial limit of the fan bracket 310 are realized, and the assembly is relatively simple and convenient, which further improves the assembly efficiency of the cooking appliance.

[0050] like Figure 5 and Figure 6 As shown, in order to prevent the plug-in rib 311 from falling out of the slot 270, the pot body in this embodiment also includes an electromagnetic wire reel 500 installed at the bottom of the insulation ring 200. The electromagnetic wire reel 500 and the insulation ring 200 form a receiving cavity for accommodating the inner pot. The socket 271 is open toward the electromagnetic wire reel 500, and the electromagnetic wire reel 500 is against the bottom of the fan assembly 300 to lower the fan assembly 300, thereby preventing the plug-in rib 311 from falling out of the slot 270. With such a design, the use of the electromagnetic wire reel 500 to lower the fan assembly 300 can prevent the plug-in rib 311 from falling out of the slot 270, thereby improving the installation reliability of the fan bracket 310 and the insulation ring 200, and there is no need to add other additional structures to prevent the plug-in rib 311 from falling out of the slot 270, so the structure is also simpler.

[0051] like Figure 1 , Figure 5 and Figure 6As shown, the electromagnetic wire reel 500 in this embodiment includes a disc frame 510 and an electromagnetic induction coil arranged on the disc frame, and a limiting step 520 is provided on the top of the disc frame 510, and the limiting step 520 includes a supporting surface 521 and a limiting surface 522, and the limiting surface 522 is sleeved on the outer side of the insulation ring 200, and the supporting surface 521 is abutted against the bottom surface of the insulation ring 200, and the limiting step 520 is abutted against the bottom of the fan assembly 300 to limit the fan assembly 300 at the bottom, and a mounting boss 530 is also provided on the outer peripheral side of the disc frame 510, and the connecting column 140 is connected to the protective plate 130, and the fastener (screw) passes through the mounting boss 530 and is locked and fixed with the connecting column 140 to fix the electromagnetic wire reel 500 on the connecting column 140. With such a design, a clamping force can be generated through the fixed connection between the electromagnetic wire reel 500 and the connecting column 140 to clamp and fix the insulation ring 200 between the middle ring 100 and the electromagnetic wire reel 500, thereby improving the installation reliability of the insulation ring 200 and further ensuring the limiting effect of the insulation ring 200 on the middle ring 100, that is, ensuring the structural strength of the middle ring 100 and effectively preventing it from deforming.

[0052] When assembling the cooking utensil of this embodiment, the first step is: the air net 400 is first installed into the vent 201 of the insulation ring 200; the second step is that the insulation ring 200 is rotated into the middle ring 100, and the vent 201 avoids the connecting column 140; the third step is: the fan 320 is assembled to the fan bracket 310 to form a fan assembly 300, and the fan assembly 300 can be quickly and integrally installed into the slot 270 on the side of the insulation ring 200; the fourth step is: the electromagnetic wire reel 500 is connected to the connecting column 140 and then installed into the middle ring 100, and the fan assembly 300 is lowered.
