Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings).

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0036] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0037] Generally, a cooking appliance will have a heating plate and a heating tube at the bottom of the inner pot. The heating plate is connected to the inner pot, and the heating tube is welded to the heating plate. Furthermore, in order to achieve real-time monitoring during the operation of the cooking appliance to ensure that it can operate normally, electrical components such as a thermostat and a temperature sensor are usually installed on the heating plate. At present, in order to reduce the difficulty of wiring between the electrical components and reduce the circuit risks caused by the setting of the electrical components, an integrated thermostat is used in some designs. The above-mentioned functions such as the thermostat and temperature sensor can be integrated together, and the integrated thermostat needs to be welded together with the heating tube.

[0038] However, in the installation process of the above-mentioned cooking appliance, the heating tube and the heating plate are first welded together, and then the integrated thermostat is installed on the heating plate, and the terminal of the integrated thermostat is welded to the cold end of the heating tube. At this time, since the relative position between the heating tube and the heating plate cannot be determined during the assembly process, the welding position of the heating tube on the heating plate may not match the preset installation position, that is, the heating tube may be offset. In this way, not only the automatic welding between the heating tube and the integrated thermostat cannot be performed, but also the welding between the heating tube and the integrated thermostat may be poor. This will not only affect the assembly efficiency of the cooking appliance, but also increase the product defect rate of the cooking appliance.

[0039] Therefore, the embodiments of the present application provide a heating component, a heating vessel and a cooking utensil. During the assembly process of the cooking utensil, the heating tube and the heating plate can be pre-positioned, so that effective welding between the temperature control module and the heating tube can be achieved, which can not only improve the assembly efficiency of the cooking utensil, but also avoid the phenomenon of poor welding between the temperature control module and the heating tube during the welding process to a certain extent.

[0040] It should be noted that the cooking utensil provided in this embodiment may be an electric steamer, an electric kettle, a food processor (including a wall-breaking machine), a health pot, an electric cooking pot, etc. In the following description, this embodiment may be understood with reference to the actual structure of the food processor.

[0041] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0042] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the partial structure of the cooking utensil provided in the embodiment of the present application. Figure 2 for Figure 1 The enlarged schematic diagram of the local structure at A in the middle. As shown in the figure, this embodiment provides a heating assembly 10, including a heating plate 1, a heating tube 2 and a temperature control module 3.

[0043] The heating plate 1 and the heating tube 2 together form a module that mainly performs the heating function in the cooking utensil, and the heating plate 1 is generally made of aluminum. Specifically, the heating plate 1 has a mounting surface 11, wherein the heating plate 1 has two surfaces disposed opposite to each other along its thickness direction, one surface is used to be fixedly connected to the bottom wall of the container 20 in the cooking utensil, and the other surface is formed as the above-mentioned mounting surface 11. Of course, in some other embodiments, the heating plate 1 can also be configured as the bottom wall of the container 20 in the cooking utensil. Here, the specific form of the heating plate 1 is not limited.

[0044] The heating tube 2 and the temperature control module 3 are both arranged on the mounting surface 11, and the temperature control module 3 is electrically connected to the first connection terminal 21 of the heating tube 2. The heating tube 2 is arranged around the temperature control module 3, wherein the temperature control module 3 can monitor and control the temperature of the food in the cooking cavity to maintain the normal operation of the cooking utensil, and to a certain extent avoid the phenomenon of short circuit or dry burning of the cooking utensil, so that the cooking utensil is safer to use.

[0045] In the process of assembling the cooking utensil, the heating tube 2 and the heating plate 1 need to be welded together first, and then assembled to the container 20 of the cooking utensil. After that, the temperature control module 3 is installed on the heating plate 1, and the first connection terminal 21 and the second connection terminal 31 of the temperature control module 3 are welded together. In this way, the assembly of the heating assembly 10 provided in this embodiment can be completed.

[0046] It should be noted that the first connecting terminal 21 is a cold pin of the heating tube.

[0047] Furthermore, the welding method between the first connection terminal 21 and the second connection terminal 31 may be spot welding, butt welding, brazing, etc. Here, the welding method between the first connection terminal 21 and the second connection terminal 31 is not specifically limited.

[0048] It is understandable that, during the assembly of the heating component 10, if the heating tube 2 and the heating plate 1 cannot be pre-positioned, the installation position of the heating tube 2 may deviate from the preset installation position, that is, the heating tube 2 may shift on the installation surface 11. In this way, when the second connecting terminal 31 and the first connecting terminal 21 are welded, the welding point between the first connecting terminal 21 and the second connecting terminal 31 may also deviate from the preset welding position, thereby causing poor welding, resulting in a high defective rate of the cooking appliance. In addition, since the installation position of the heating tube 2 cannot be determined, it is difficult for the cooking appliance to achieve low-cost intelligent manufacturing (LCIM), which not only increases production costs but also reduces production efficiency.

[0049] Therefore, in order to overcome this defect, during the welding process of the heating plate 1 and the heating tube 2 , the heating tube 2 and the heating plate 1 may be pre-positioned, and then the heating tube 2 may be welded to the heating plate 1 .

[0050] Based on this, in the heating assembly 10 provided in the present embodiment, a positioning structure 4 is further provided on the heating plate 1, and the positioning structure 4 abuts against the heating tube 2 to prevent the heating tube 2 from moving on the mounting surface 11. The movement here can be understood as the movement or rotation of the heating tube 2 on the mounting surface 11. In this way, in the process of assembling the heating assembly 10, the relative position between the heating tube 2 and the heating plate 1 can be determined by the positioning structure 4 first, and then the heating tube 2 can be welded to the heating plate 1. In this way, the installation position of the heating tube 2 on the heating plate 1 will be closer to the preset installation position of the heating tube 2, thereby improving the welding accuracy between the temperature control module 3 and the heating tube 2, so as to avoid the occurrence of poor welding and the like to a certain extent, which can not only improve the assembly efficiency of the cooking utensil provided in the present embodiment, but also improve the product yield of the cooking utensil provided in the present embodiment.

[0051] At present, in order to reduce the wiring difficulty of the temperature control module 3 and to improve the assembly efficiency of the temperature control module 3, devices with various functions are usually integrated together. Therefore, in a specific implementation of this embodiment, the temperature control module 3 includes a fixed bracket 32 ​​and a temperature control component 33 connected together, the fixed bracket 32 ​​is connected to the heating plate 1, and the temperature control component 33 is electrically connected to the second connecting terminal 31.

[0052] Please combine Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the three-dimensional structure of the temperature control module in the heating assembly provided in the embodiment of the present application. Figure 4 for Figure 3 Schematic diagram of the three-dimensional structure from another perspective. The temperature control component 33 includes a temperature sensor probe 331, a temperature controller 332, a grounding terminal 333 and a thermal fuse 334. The temperature sensor probe 331, the temperature controller 332, the grounding terminal 333 and the thermal fuse 334 are arranged at intervals along the circumference of the fixed bracket 32. In order to realize the electrical connection between the temperature control component 33 and other modules, the fixed bracket 32 ​​should also be provided with a wiring terminal 34. Here, the specific relationship between the electrical connection between the temperature control component 33 and other devices or modules is not introduced.

[0053] In order to achieve the connection between the fixed bracket 32 ​​and the heating plate 1, in some specific embodiments, the fixed bracket 32 ​​includes a bracket body 321 and a connecting portion 322 connected together, the temperature control component 33 is arranged on the bracket body 321, the connecting portion 322 is connected to the peripheral outer edge of the bracket body 321, and is detachably connected to the heating plate 1 through fasteners.

[0054] In this way, by setting the connecting portion 322 on the bracket body 321, the connection between the fixed bracket 32 ​​and the heating plate 1 can be achieved, so that when the temperature control module 3 is installed, the temperature control module 3 and the heating plate 1 can be fastened by fasteners first, which can also be understood as pre-positioning the temperature control module 3, and then the second connecting terminal 31 and the first connecting terminal 21 are welded together. In this process, after the temperature control module 3 and the heating plate 1 are connected together, the installation position of the temperature control module 3 can be determined, so that the installation position of the temperature control module 3 is closer to the preset installation position, so that in the process of welding the second connecting terminal 31 and the first connecting terminal 21, the phenomenon of poor welding can be avoided.

[0055] It should be noted that the connection portion 322 and the heating plate 1 can be detachably connected by threaded fasteners such as screws. Here, there is no specific limitation on the fasteners that connect the connection portion 322 and the heating plate 1 together.

[0056] From the above, it can be known that the position of the heating tube 2 can be pre-positioned by setting the positioning structure 4, and the positioning of the heating tube 2 includes the positioning of the heating tube 2 in the radial direction of the heating plate 1 and the positioning of the heating tube 2 in the circumferential direction of the heating plate 1.

[0057] The heating tube 2 can be positioned radially on the heating plate 1 by making the positioning structure 4 abut against two opposite sides of the heating tube 2. The opposite sides here can be understood as the side of the heating tube 2 facing the center of the heating plate 1 and the side of the heating tube 2 away from the center of the heating plate 1. In this way, the heating tube 2 is clamped by the positioning structure 4, and the position of the heating tube 2 in the radial direction of the heating plate 1 can be limited.

[0058] The positioning of the heating tube 2 in the circumferential direction of the heating plate 1 can be determined according to the specific structure of the heating tube 2. Figure 5 , Figure 5 A schematic diagram of the partial structure of the heating assembly provided in the embodiment of the present application. Thus, in a specific implementation of the present embodiment, the heating tube 2 further includes a heating body 22; the heating body 22 includes an arc portion 221 and a straight portion 222 connected together, the arc portion 221 is connected to the first connection terminal 21, and the positioning structure 4 includes a plurality of positioning protrusions 41, and at least part of the positioning protrusions 41 abut against opposite sides of the straight portion 222.

[0059] In this way, both sides of the straight portion 222 along its own extension direction are supported by the positioning protrusion 41. That is to say, even if the heating tube 2 has a tendency to rotate, the two sides of the straight portion 222 along its own extension direction will be stuck and unable to rotate due to the stopping of the positioning protrusion 41. Therefore, the positioning structure 4 can limit the position of the heating tube 2 in the circumferential direction of the heating plate 1, that is, the positioning structure 4 can prevent the heating tube 2 from rotating on the heating plate 1.

[0060] Among them, a plurality of positioning protrusions 41 can be arranged in pairs to respectively abut against the opposite sides of the heating tube 2; a plurality of positioning protrusions 41 can also be staggered on the opposite sides of the heating tube 2. The paired arrangement here can be understood as the positioning protrusion 41 located on the side of the heating tube 2 close to the center of the heating plate 1 and the positioning protrusion 41 located on the side of the heating tube 2 away from the center of the heating plate 1 are arranged opposite to each other in the radial direction of the heating plate 1, and the staggered distribution can be understood as the positioning protrusion 41 located on the side of the heating tube 2 close to the center of the heating plate 1 and the positioning protrusion 41 located on the side of the heating tube 2 away from the center of the heating plate 1 are arranged at intervals in the circumferential direction of the heating plate 1. Regardless of which method is adopted and regardless of the shape of the heating tube 2, the heating tube 2 can be clamped by the positioning structure 4 to limit the position of the heating tube 2 in the radial direction of the heating plate 1.

[0061] In the specific implementation of this embodiment, the positioning structure 4 can be further restricted in combination with the specific shape of the heating tube 2. Specifically, in this embodiment, the arc portion 221 includes a first arc segment 2211 and a second arc segment 2212 that are arranged opposite to each other, and the first arc segment 2211 and the second arc segment 2212 are both recessed to a side away from the center of the heating plate 1, there are two first connecting terminals 21, and they are respectively connected to the first arc segment 2211 and the second arc segment 2212, and the straight portion 222 is connected between the first arc segment 2211 and the second arc segment 2212, that is, the straight portion 222 is arranged opposite to the two first connecting terminals 21; the positioning protrusion 41 includes a first positioning protrusion 411, a second positioning protrusion 412 and a plurality of third positioning protrusions 413; the first positioning protrusion 411 is abutted against the first arc segment 2211, the second positioning protrusion 412 is abutted against the second arc segment 2212, and the plurality of third positioning protrusions 413 are abutted against the opposite sides of the straight portion 222.

[0062] In this way, the first arc segment 2211, the second arc segment 2212 and the straight portion 222 can all be pre-positioned, so that the positioning structure 4 has a better positioning effect on the heating tube 2, and the installation position of the heating tube 2 is closer to the preset installation position of the heating tube 2, which can further avoid the occurrence of poor welding during the subsequent welding of the first connecting terminal 21 and the second connecting terminal 31.

[0063] Since the first arc segment 2211 and the second arc segment 2212 are recessed toward the side away from the center of the heating disk 1, if the first positioning protrusion 411 is abutted against the side of the first arc segment 2211 away from the center of the heating disk 1, and the second positioning protrusion 412 is abutted against the side of the second arc segment 2212 away from the center of the heating disk 1, at this time, the first arc segment 2211 and the second arc segment 2212 will both move toward the side facing the center of the heating disk 1, that is, the first positioning protrusion 411 and the second positioning protrusion 412 cannot play a substantial positioning role on the first arc segment 2211 and the second arc segment 2212.

[0064] Therefore, in this embodiment, the first positioning protrusion 411 abuts against the side of the first arc segment 2211 facing the center of the heating disk 1, and the second positioning protrusion 412 abuts against the side of the second arc segment 2212 facing the center of the heating disk 1; the third positioning protrusion 413 is arranged in pairs and abuts against the side of the straight portion 222 facing the center of the heating disk 1 and the side away from the center of the heating disk 1.

[0065] In this way, the radial position of the first arc segment 2211 and the second arc segment 2212 in the heating plate 1 can be limited, and the radial and circumferential position of the straight portion 222 in the heating plate 1 can be limited, so that the positioning structure 4 can limit the radial and circumferential position of the heating tube 2 in the heating plate 1.

[0066] In a specific implementation of this embodiment, the first positioning protrusion 411 is set to one, the second positioning protrusion 412 is set to one, and the third positioning protrusion 413 is set to two pairs, that is, four. In other implementations, the first positioning protrusion 411 and the second positioning protrusion 412 can be set to two or more, and the third positioning protrusion 413 can be set to three or more pairs. Here, there is no specific limitation on the number of the first positioning protrusion 411, the second positioning protrusion 412, and the third positioning protrusion 413.

[0067] From the above, it can be seen that the first connecting terminal 21 is welded to the second connecting terminal 31. Therefore, the pre-positioning of the first arc segment 2211 and the pre-positioning of the second arc segment 2212 are essentially the pre-positioning of the two first connecting terminals 21. That is to say, when the first positioning protrusion 411 and the second positioning protrusion 412 are arranged closer to the two first connecting terminals 21, the positioning effect is better.

[0068] Therefore, in some specific embodiments, the first positioning protrusion 411 abuts against a position of the first arc segment 2211 that is closer to the first connection terminal 21 than the straight portion 222, and the second positioning protrusion 412 abuts against a position of the second arc segment 2212 that is closer to the first connection terminal 21 than the straight portion 222. In this way, after the heating tube 2 is welded to the heating plate 1, the positions of the two first connection terminals 21 will be closer to the preset positions of the two first connection terminals 21, so as to achieve the subsequent effective welding of the second connection terminal 31 and the first connection terminal 21.

[0069] As for the setting mode of the positioning protrusion 41, it can be welded to the heating plate 1 or formed by other forming methods. It is understandable that the cost of welding is relatively high. Therefore, in some embodiments, the heating plate 1 includes a plate body 12, a mounting surface 11 is formed on the plate body 12, and the heating tube 2 and the temperature control module 3 are both connected to the plate body 12; the positioning protrusion 41 is formed by stamping the plate body 12. In this way, by forming the positioning protrusion 41 on the plate body 12 by stamping, the cost of forming the positioning protrusion 41 is relatively low, so that the manufacturing cost of the heating assembly 10 provided in this embodiment is relatively low.

[0070] It can be understood that when the positioning protrusion 41 is formed by stamping, the free end of the positioning protrusion 41 will be farther away from the center of the heating plate 1 than the root of the positioning protrusion 41. In this way, the deformation of the positioning protrusion 41 can be increased. On the one hand, it is convenient to achieve the positioning between the heating tube 2 and the heating plate 1. On the other hand, it can increase the supporting force applied by the positioning protrusion 41 to the heating tube 2, so that the positioning structure 4 can effectively position the heating tube 2.

[0071] This embodiment also provides a heating vessel, comprising a container 20 and the heating assembly 10 in the above embodiment; the container 20 is connected to the heating plate 1. The specific structure of the heating assembly 10 has been described in detail in the above embodiment, and will not be repeated here.

[0072] It should be noted that the heating vessel provided in this embodiment should also include structural parts such as a cover body, and other components included in the heating vessel provided in this embodiment will not be introduced one by one here.
