In addition, similar models often use the same set of hardware solutions, and the same set of hardware can be installed on different models by changing the length and routing of the connecting wires between the coupler and the circuit board. This leads to unstable EMI performance of different machines of the same model and different models. Utility Model Content

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
[0042] like Figures 1 to 3 As shown, an electrical connection structure of a cooking appliance includes a power board 1 and a coupler 2 fixed to the power board 1, the coupler 2 has a plug end 22 for plugging with a power cord, and a connection end 21 for electrically connecting to the power board 1, the power board 1 has a connection area 11, and the connection end 21 is located in the connection area 11.
[0043] In the present invention, the plug end 22 of the coupler 2 is used for plugging and coupling with the power cord, and the connection end 21 is used for connecting with the power board 1, wherein the power board 1 has a connection area 11, and the connection end 21 is located in the connection area 11, so that the power board 1 and the coupler 2 are fixed as a whole by direct or indirect fixing to form a stable component. It can be understood that the connection end 21 is located in the connection area 11, which means that at least part of the area of the coupler 2 overlaps with the power board 1, so that the two are fixed to form an integral component, and the two cannot be separated.
[0044] During assembly, the assembly formed by the power board 1 and the coupler 2 can be fixed to the machine, so that the power board 1 and the coupler 2 are fixed at the same position of the machine at the same time, and the distance between the two is kept fixed even on machines of different models, so that whether the electrical connection between the connection terminal 21 and the power board 1 is achieved through a wire, or the electrical connection is directly achieved through welding, stable conduction and EMI performance can be maintained. In addition, the connection terminal 21 and the power board 1 can be connected in advance with a connecting wire, so that the power board 1, the coupler 2 and the connecting wire together form a module, realizing the modular design of the electrical connection structure, facilitating assembly line production and manufacturing, and at the same time, the wire arrangement of the module is consistent, and the conduction performance is more stable. In addition, the length of the connecting wire can be greatly shortened, and while optimizing the internal layout of the machine, it also avoids the problem of the connecting wire passing through many other electrical components and being subject to electromagnetic interference.
[0045] It should be noted that the present invention does not limit the fixing method of the power board 1 and the coupler 2, which can be one of the following embodiments:
[0046] Implementation method 1: In this implementation method, Figure 1 As shown, the coupler 2 is welded and fixed to the power board 1 , the plug end 22 faces the side away from the power board 1 , and the connection end 21 faces the power board 1 .
[0047] In this embodiment, the coupler 2 is directly fixed to the power board 1 by welding, and the connection end 21 of the coupler 2 faces the power board 1, so that the electrical connection between the two is simpler and more convenient, and the distance is shorter. Therefore, direct electrical connection can be achieved by welding, and a shorter connecting wire can be used to connect the connection end 21 to the power board 1. In addition, the welding method also makes the connection between the power board 1 and the coupler 2 more stable, reduces the risk of the two being loose, and improves the stability of the structure and conduction.
[0048] Implementation method 2: In this implementation method, if Figure 2 , Figure 3 As shown, the electrical connection structure also includes a fixing bracket 3, the fixing bracket 3 has a first fixing position 31 and a second fixing position 32, the power board 1 is installed at the first fixing position 31, and the coupler 2 is installed at the second fixing position 32, so that the coupler 2 is fixed to the power board 1 through the fixing bracket 3.
[0049] In this embodiment, the coupler 2 is fixed to the power board 1 as a whole through the fixing bracket 3, so that the power board 1 and the coupler 2 are indirectly fixed, so there is no need to improve the structure of the coupler 2 and the power board 1 respectively, and the problems of difficult positioning and processing errors caused by direct fixing of the two can be improved, thereby reducing the difficulty of processing. The fixing bracket 3 can directly process a fixing structure, so as to facilitate fixing with the machine and reduce the difficulty of installing the power board 1 and the coupler 2.
[0050] Specifically, Figure 3 As shown, the fixing bracket 3 is provided with a mounting rib 33 extending along its own circumference, the mounting rib 33 encloses the first fixing position 31, and a partial area of the mounting rib 33 is provided with an avoidance groove, and the avoidance groove constitutes the second fixing position 32.
[0051] The mounting ribs 33 enclose the first fixing position 31, which is used to fix the power board 1. The mounting ribs 33 form the installation position of the power board 1, ensuring that the power board 1 is fixed at the preset position of the fixing bracket 3 to prevent the power board 1 from shifting. The mounting ribs 33 are partially provided with a notch, forming a second fixing position 32 for fixing the coupler 2. After the coupler 2 is fixed, a partial area is located in the first fixing position 31, thereby further reducing the distance between the coupler 2 and the power board 1 and shortening the length of the connecting wire. At the same time, the setting of the avoidance groove can also reduce the overall height of the coupler 2 after it is installed on the fixing bracket 3, thereby making the volume of the electrical connection structure smaller and applicable to more models, especially miniaturized models.
[0052] Preferably, if Figure 2 , Figure 3 As shown, the fixing bracket 3 is provided with protruding fixing ribs 34 on its circumference. There are at least two fixing ribs 34 which are arranged oppositely on both sides of the first fixing position 31 . The fixing ribs 34 are used for fixed connection with the pot body 4 .
[0053] like Figure 3 As shown, the fixing ribs 34 are arranged on both sides of the first fixing position 31 along the diagonal line of the first fixing position 31 to ensure the stability of the fixing ribs 34 to the pot body 4. Figure 3As shown, the fixing rib 34 is provided with a fixing hole 341 , and the pot body 4 is correspondingly provided with a screw column 43 , and a fastener (such as a screw, etc.) passes through the fixing hole 341 and is fastened to the screw column 43 .
[0054] Furthermore, if Figure 3 As shown, a fixing column 35 is disposed in the first fixing position 31 , and the power board 1 is fixed to the fixing column 35 , so that a heat dissipation gap is provided between the power board 1 and the fixing bracket 3 .
[0055] The fixing column 35 protrudes from the first fixing position 31, so that after the power board 1 is fixed to the fixing column 35, there is a heat dissipation gap between the power board 1 and the inner wall of the first fixing position 31, and they do not contact each other. This increases the contact area between the power board 1 and the air, and improves the heat dissipation effect of the power board 1. At the same time, the vibration transmitted from the fixing bracket 3 to the power board 1 can be alleviated, making the position of the power board 1 and the link connection more stable.
[0056] like Figures 4 to 7 As shown, the utility model also discloses a cooking utensil, including a pot body 4, and also includes the electrical connection structure of the above-mentioned cooking utensil, the electrical connection structure is fixed to the pot body 4, the outer surface of the pot body 4 is provided with an opening, and the plug end 22 is exposed at the opening.
[0057] After the electrical connection structure is fixed to the pot body 4, the plug-in end 22 of the coupler 2 is exposed on the outer surface of the pot body 4, so that the user can easily plug the power cord into the coupler 2, thereby improving the convenience of use.
[0058] Furthermore, if Figure 4 , Figure 5 , Figure 7 As shown, the pot body 4 is provided with a mounting position 41 for mounting the power board 1 , and the mounting position 41 is provided with a clamping rib 42 , and the clamping rib 42 is clamped and fixed with the coupler 2 .
[0059] During use, the user needs to frequently plug or unplug the power cord into or out of the coupler 2. After the electrical connection structure is fixed to the pot body 4, the clamping ribs 42 of the pot body 4 are clamped and fixed with the coupler 2, thereby forming multiple fixations on the coupler 2, improving the fixing stability of the coupler 2, reducing the shaking of the coupler 2 and the power board 1 when the user plugs or unplugs the power cord, and ensuring the structural and conductive stability.
[0060] Furthermore, after the electrical connection structure composed of the coupler 2 and the power board 1 is fixed to the pot body 4, the clamping rib 42 is clamped and fixed to the coupler 2. In addition, the coupler 2 is fastened to the pot body 4 by fastening screws, thereby forming a triple fixation for the coupler 2, which greatly ensures the stability of the coupler 2 and the plug-in reliability.
[0061] Preferably, if Figure 6 , Figure 7 As shown, the plug-in end 22 has a plug-in slot for mating with a power cord, and a fixing lug 23 surrounding the outer circumference of the plug-in slot. The pot body 4 is provided with a stop rib, which forms a mating slot 44, and the fixing lug 23 is located in the mating slot 44.
[0062] The fixing lug 23 is located in the matching groove 44, and the groove wall of the matching groove 44 forms a limit for the fixing lug 23, which can not only improve the positioning effect of the coupler 2 when installing the coupler 2 and reduce the difficulty of installation, but also stop and limit the coupler 2 during use to ensure the stable position of the coupler 2 and reduce shaking during plugging and unplugging.
[0063] The fixing lug 23 and the groove wall of the matching groove 44 are respectively provided with screw holes so that fasteners can pass through and fix the two.
[0064] Preferably, if Figure 1 , Figure 6 As shown, the power strip 1 has a connection side 12 , the coupler 2 is fixed to the connection side 12 , the power strip 1 is fixed to the bottom wall of the pot body 4 , and the connection side 12 faces the bottom wall of the pot body 4 .
[0065] The connection side 12 of the power board 1 faces the bottom wall of the pot body 4, and thus faces away from the inner pot above, which can prevent the inner pot from interfering with the connection side 12 of the power board 1 when it moves downward under the pressure of food, thereby preventing the power board 1 from being damaged. It can also prevent food residues, water, oil and other impurities from dripping onto the power board 1, thereby affecting the service life of the power board 1.

[0067] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.
