Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more specifically, to a pot body and a cooking utensil. Background Technology

[0002] In the relevant solutions, electric heaters that use heating plates limit the movement of the pot body and the heating plate by setting a ring of short ribs on the bottom wall of the pot. This limiting method causes the pot body to move a lot in the horizontal direction, and the user cannot easily notice when the pot body is not in the correct position, resulting in poor heating effect and poor user experience.

[0003] Therefore, designing an electric heating pot that allows users to promptly detect when the pot body is not properly installed has become an urgent problem to be solved. Utility Model Content

[0004] This application aims to at least solve the technical problem in the prior art or related technologies that users cannot promptly detect when the pot body of an electric heating pot is not properly installed.

[0005] Therefore, the first aspect of this application is to propose a pot body.

[0006] The second aspect of this application is to propose a cooking utensil.

[0007] An embodiment of the first aspect of this application provides a pot body for a cooking utensil. The cooking utensil includes a heating base and a pot body. The heating base includes one of a heating plate, a first limiting groove, and a first limiting rib. The heating plate is used to support and heat the pot body. The pot body includes: a bottom wall; the other of the first limiting groove and the first limiting rib is disposed on the outer wall surface of the bottom wall; and a second limiting rib is disposed on the outer wall surface of the bottom wall and can cooperate with the heating plate to limit the installation position of the pot body on the heating plate. The first limiting rib is located within the first limiting groove when the pot body and the heating plate are assembled in the use state, and is supported on the heating plate or on the outer wall surface of the bottom wall when the pot body and the heating plate are not in use.

[0008] The pot body provided by this utility model is used in cooking appliances. The cooking appliance includes a pot body and a heating base. The heating base includes a bottom shell and a heating plate. The heating plate is installed on the bottom shell to support and heat the pot body. A second limiting rib is provided on the pot body. The second limiting rib can cooperate with the heating plate to position the pot body on the heating plate. Specifically, the second limiting rib can be located at the edge of the heating plate, thus defining the installation position of the pot body. This limiting method reduces the likelihood of collisions between the pot body and the heating base during installation, thereby lowering the probability of damage to the pot body's exterior surface due to impacts.

[0009] Furthermore, the outer bottom wall of the pot body is provided with one of a first limiting rib and a first limiting groove, and the heating base is provided with the other of a first limiting rib and a first limiting groove. When the pot body is correctly installed on the heating plate, the pot body and the heating plate are assembled into a usable state. At this time, the cooperation of the first limiting rib and the first limiting groove can provide secondary limiting for the pot body, thereby making the positioning and installation of the pot body on the heating plate more precise and improving the positioning accuracy of the pot body. When the pot body is not correctly installed on the heating plate, the position of the pot body is not in place, and the first limiting rib cannot be engaged in the first limiting groove. In this case, if the first limiting rib is located on the pot body, it will be supported on the heating plate, causing the pot body to tilt at a large angle relative to the heating plate, allowing the user to quickly see that the pot body is not installed correctly. If the first limiting rib is located on the bottom shell, it will be supported on the bottom wall of the pot, also causing the pot body to tilt at a large angle relative to the heating plate, allowing the user to quickly see that the pot body is not installed correctly. Therefore, through the cooperation of the first limiting rib and the first limiting groove, on the one hand, the installation of the pot body and the heating plate can be repositioned, improving the positioning and installation accuracy of the pot body. On the other hand, through the cooperation of the first limiting rib and the first limiting groove, the pot body can produce a visually visible assembly step error when it is not installed in place, which makes it easy for the user to correct the placement of the pot body in time. This ensures the heating effect of the heating plate and improves the user experience.

[0010] In this application, the first limiting rib can also be called the foolproof rib. The first limiting rib can ensure that the pot body can be installed in place, thus achieving the effect of foolproof installation.

[0011] In any of the above embodiments, optionally, the heating base includes a first limiting groove, and the pot body includes a first limiting rib, the first limiting rib and the bottom wall of the pot being an integral structure.

[0012] In this embodiment, the first limiting groove is disposed on the heating base. A first limiting rib is provided on the pot body, thereby simplifying the pot body structure. Making the first limiting rib and the pot body an integral structure, or machining the first limiting rib and the pot body integrally, ensures the connection strength between the first limiting rib and the pot body.

[0013] In any of the above embodiments, optionally, the heating base includes a first limiting groove, and the pot body includes a first limiting rib, wherein the height dimension of the first limiting rib along the height direction of the pot body is less than or equal to the height dimension of the second limiting rib along the height direction of the pot body.

[0014] In this embodiment, when a first limiting rib and a second limiting rib are provided on the pot body, the height of the first limiting rib is lower than or flush with the second limiting rib, so that a supporting plane can be formed by the second limiting rib to facilitate the placement of the pot body on a flat surface such as a stove.

[0015] In any of the above embodiments, optionally, there are one or more second limiting ribs. When there are multiple second limiting ribs, the multiple second limiting ribs are disposed on the edge of the pot body, and the first limiting rib is disposed in the middle of the bottom wall of the pot.

[0016] In this embodiment, the number of second limiting ribs is not limited; there can be one or more. When there are multiple second limiting ribs, they can be placed on the edge of the pot body to facilitate the limiting engagement between the second limiting ribs and the edge of the heating plate. The first limiting rib is placed in the middle of the bottom wall of the pot, which allows the pot body to tilt at a larger angle relative to the heating plate when it is not installed properly, making it easier for the user to notice in time. Conversely, if the first limiting rib is placed on the edge of the pot body, the tilt angle of the pot body relative to the heating plate will be smaller when it is not installed properly, making it less likely for the user to notice that the pot body is not installed properly.

[0017] The bottom wall of the pot body is elongated, with multiple second limiting ribs located at the four corners of the pot body. The first limiting rib is located in the middle of the outer bottom wall of the pot body.

[0018] For designs with a long, rectangular pot body, the increased length makes improper installation more likely, and this is particularly difficult to detect. By incorporating a first limiting rib, the tilt angle of the long, rectangular pot body after installation is amplified, creating a visually noticeable assembly step error when it is not installed correctly, allowing the user to correct the pot's placement immediately. Therefore, incorporating a first limiting rib on the long, rectangular pot body significantly improves the situation regarding improper installation.

[0019] Of course, in other designs, the pot body can also be round.

[0020] In any of the above embodiments, optionally, a first guide surface is provided on the first limiting rib, which is used to guide the first limiting rib to be inserted into the first limiting groove when the pot body is installed on the heating plate.

[0021] In this embodiment, by setting a first guide surface, when the first limiting rib is located near the first limiting groove, the first limiting rib can slide into the first limiting groove under the action of the first guide surface, thereby increasing the probability of the pot body being installed in place.

[0022] In any of the above embodiments, optionally, a second guide surface is provided on the second limiting rib, the second guide surface being used to guide the second limiting rib to be limited to the edge of the heating plate when the pot body is installed on the heating plate.

[0023] In this embodiment, by providing a second guide surface, when the second limiting rib is located at the edge of the heating plate, the second limiting rib can slide into the edge of the heating plate with the help of the guidance of the second guide surface. In this way, the pot body and the heating plate can be guided and installed by the second guide surface during the installation process.

[0024] In any of the above embodiments, optionally, when the pot body and the heating plate are assembled into a usable state, a gap is provided between the second limiting rib and the heating plate along the edge to the center direction of the pot body.

[0025] In this embodiment, when the pot body and the heating plate are assembled into a usable state, a gap is provided between the second limiting rib and the heating plate, which makes it easier for the second limiting rib on the edge of the pot body to engage with the edge of the heating plate, making the installation of the pot body more convenient.

[0026] In any of the above embodiments, optionally, the gap is greater than or equal to 0.5 mm and less than or equal to 3 mm.

[0027] In this embodiment, the gap cannot be set too small. If it is too small, the second limiting rib may interfere with the heating plate, affecting the installation of the pot. If the gap is too large, the installation position of the pot will not be accurate enough, requiring additional adjustment of the pot's installation position, making installation inconvenient. Taking all factors into consideration, setting the gap in the range of 0.5mm-3mm ensures a suitable distance between the second limiting rib and the heating plate.

[0028] The second aspect of this utility model provides a cooking appliance, including: a heating base, the heating base including a heating plate and one of a first limiting groove and a first limiting rib; a pot body as in any embodiment of the first aspect; wherein the first limiting rib is located in the first limiting groove when the pot body and the heating plate are assembled in the use state, and is supported on the outer wall surface of the heating plate or the bottom wall of the pot body when the pot body and the heating plate are not in the use state.

[0029] The second aspect of this utility model provides a cooking utensil. Since the cooking utensil provided by this utility model includes the pot body of any embodiment of the first aspect of this utility model, it has all the beneficial effects of the pot body of any embodiment of the first aspect of this utility model.

[0030] In any of the above embodiments, optionally, the heating plate includes two plates spaced apart along a first direction, and the gap between the two plates along the first direction forms a first limiting groove.

[0031] In this embodiment, the heating plate is not a single structure, but rather composed of multiple plates. At least two plates are spaced apart along a first direction, forming a first limiting groove through the gap between the two plates, thus simplifying the overall structure of the heating base.

[0032] The first direction can be specifically the length direction or the width direction of the pot body.

[0033] In any of the above embodiments, optionally, the heating base further includes: a bottom shell, a heating plate mounted on the bottom shell, the heating plate including at least two plates; and a plurality of elastic floating components disposed between the plates and the bottom shell, so that the plates can float on the bottom shell along the height direction of the heating base.

[0034] In this embodiment, the heating base further includes multiple elastic floating components. At least two plates are mounted on the bottom shell to support and heat the pot. There can be two to four plates, for example, two. Multiple elastic floating components are disposed between each plate and the bottom shell, allowing the plates to float up and down under the action of the elastic floating components. After the pot is placed on the heating base, the plates descend under the weight of the pot, compressing the elastic elements in the elastic floating components. These elastic elements then apply a restoring force to the plates, ensuring a tight fit between the plates and the pot. This improves the adhesion between the heating base and the pot after installation, thereby enhancing the heating effect of the plates on the pot.

[0035] This structure, with its multiple plates, allows different plates to heat different areas of the pot, achieving zoned heating of the heating base. This results in higher heating efficiency and more even heating across all areas. Furthermore, the multiple plates provide a basis for zoned temperature control in each area.

[0036] In some embodiments, optionally, at least two discs are arranged independently of each other, and each disc and the bottom shell are provided with an elastic floating component.

[0037] In this embodiment, the disks are completely independent, meaning that different disks are completely separate. Furthermore, each disk and its base are equipped with a corresponding elastic floating component, meaning the elastic floating components for different disks are also completely independent. This arrangement allows each disk to float independently without interference between them. This enables different disks to heat different areas, allowing for separate heating of multiple areas through multiple independent disks, thus achieving zoned heating.

[0038] In some embodiments, optionally, an elastic floating component is provided between each disk body and the bottom shell, the elastic floating component being disposed between the middle of the disk body and the bottom shell.

[0039] In this embodiment, when the elastic floating component is set to a large size, only one elastic floating component is needed. In this case, the elastic floating component can be set between the middle of the disk body and the bottom shell, which reduces the number of elastic floating components used and makes assembly easier.

[0040] In some embodiments, optionally, at least three elastic floating components are provided between each disk body and the bottom shell, with the at least three elastic floating components disposed between the edge of the disk body and the bottom shell.

[0041] In this embodiment, considering the difficulty in sourcing materials for large elastic floating components, multiple small elastic floating components can be arranged along the edge of the pan. This arrangement makes material sourcing easier and helps maintain the balance of the pan, especially when the pot is placed unevenly. The pan can be set at different angles to follow the pot, ensuring that the pan and pot remain in contact at different angles. Optionally, there can be 3, 4, or 5 elastic floating components, and the central angles of any two adjacent elastic floating components are the same.

[0042] In some embodiments, the heating plate may optionally include at least two plates, the edges of which are provided with a first chamfer to guide the first limiting rib, and / or the edges of which are provided with a second chamfer to guide the second limiting rib.

[0043] In this embodiment, when the heating plate consists of at least two plates, a second chamfer is provided on the edge of each plate, and a second limiting rib can move along the second chamfer to guide the second limiting rib, thereby achieving installation guidance between the pot body and the plates. A first chamfer is provided on the edge of each plate, and a first limiting rib can move along the first chamfer to guide the first limiting rib into the first limiting groove. The guidance provided by the first and / or second chamfers makes the installation of the pot body smoother and more convenient.

[0044] In some embodiments, the cooking appliance may optionally include at least one of a multi-cooker, an electric pressure cooker, and a rice cooker.

[0045] In some embodiments, the heating base may optionally include: at least two thermostats mounted on the base shell and corresponding to at least two plates, for detecting the temperature of the pot and / or the corresponding plate; and a control device for controlling the operation of the corresponding plate according to the temperature detected by each thermostat.

[0046] In this embodiment, at least two thermostats are installed on the bottom shell, corresponding one-to-one with at least two pans. That is, the number of pans is the same as the number of thermostats. Each thermostat can detect the temperature of the pot and / or its corresponding pan. The control device is used to control the operation of its corresponding pan according to the temperature detected by each thermostat, thereby realizing independent control of each pan. In this way, the heating power and start / stop of each pan can be controlled separately according to actual needs, so that the heating temperature of different areas of the pot can be controlled separately.

[0047] In some embodiments, optionally, the pan body is provided with clearance holes, and at least two thermostats are respectively provided at the clearance holes of at least two pan bodies, and at least a part of each thermostat can extend into the corresponding clearance hole and contact the pan body to detect the temperature of the pan body.

[0048] In this embodiment, each plate is provided with a clearance hole, and at least a portion of the thermostat can extend into the clearance hole and contact the pot body to detect the pot body temperature. This design allows the thermostat to directly detect the pot body temperature and then control the operation of each plate based on that temperature. This enables zoned heating control of the pot body based on the temperature of different areas. Directly detecting the pot body temperature to control the plate operation allows for more precise temperature control. Of course, in other embodiments, the thermostat can also directly detect the temperature of different areas of the plate and then control the temperature of different plates based on those temperatures.

[0049] In some embodiments, optionally, at least two discs have the same shape.

[0050] In this embodiment, at least two disks have the same shape, so only one type of disk needs to be designed, resulting in faster manufacturing efficiency. Of course, depending on the requirements, the shapes of the at least two disks can also be different. In actual production, the shapes of the disks can be designed according to different needs.

[0051] In some embodiments, the disk body may optionally be at least one of a square disk, a circular disk, or an oval disk. The shape of the disk body can be selected as needed, and it can be square, circular, or oval, but is not limited to these shapes.

[0052] Optionally, each plate includes a heat-conducting plate and a heating element, with the heating element mounted on the back of the heat-conducting plate. The front of the plate is used to contact the pot body to heat and support the pot body.

Detailed Implementation

[0063] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0064] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0065] The following reference Figures 1 to 6 This application describes the pot body 2 and cooking utensils provided in some embodiments.

[0066] like Figures 1 to 6As shown, an embodiment of the first aspect of this application provides a pot body 2 for a cooking utensil. The cooking utensil includes a heating base 1 and a pot body 2. The heating base 1 includes a heating plate 12 and one of a first limiting groove 14 and a first limiting rib 22. The heating plate 12 is used to support and heat the pot body 2. The pot body 2 includes: a bottom wall 20; the other of the first limiting groove 14 and the first limiting rib 22 is disposed on the outer wall surface of the bottom wall 20; a second limiting rib 24 is disposed on the outer wall surface of the bottom wall 20 and can cooperate with the heating plate 12 to limit the installation position of the pot body 2 on the heating plate 12; wherein, as Figure 1 , Figure 2 and Figure 3 As shown, the first limiting rib 22 can be positioned within the first limiting groove 14 when the pot body 2 and the heating plate 12 are assembled into a usable state. Figure 4 and Figure 5 As shown, when the pot body 2 and the heating plate 12 are not in use, the first limiting rib 22 is supported on the heating plate 12 or on the outer wall surface of the bottom wall 20 of the pot.

[0067] The pot body 2 provided by this utility model is used as a cooking utensil. The cooking utensil includes a pot body 2 and a heating base 1. The heating base 1 includes a bottom shell 10 and a heating plate 12. The heating plate 12 is installed on the bottom shell 10 to support and heat the pot body 2. A second limiting rib 24 is provided on the pot body 2. The second limiting rib 24 can cooperate with the heating plate 12 to limit the installation position of the pot body 2 on the heating plate 12. Specifically, the second limiting rib 24 can be limited to the edge of the heating plate 12, so that the installation position of the pot body 2 can be limited by the heating plate 12. With this limiting method, the pot body 2 and the heating base 1 are less likely to collide during the installation of the pot body 2, thereby avoiding the limiting rib on the heating base from scratching the coating on the pot body and reducing the probability of damage to the appearance of the pot body 2 and the heating base 1 due to collisions.

[0068] Furthermore, the outer bottom wall of the pot body 2 is provided with one of the first limiting rib 22 and the first limiting groove 14, and the heating base 1 is provided with the other of the first limiting rib 22 and the first limiting groove 14. When the pot body 2 is correctly installed on the heating plate 12, the pot body 2 and the heating plate 12 are assembled into a usable state. At this time, through the cooperation of the first limiting rib 22 and the first limiting groove 14, the pot body 2 can be limited a second time, so that the positioning and installation of the pot body 2 on the heating plate 12 can be more accurate, and the positioning accuracy of the pot body 2 can be improved. When the pot body 2 is not correctly installed on the heating plate 12, the position of the pot body 2 is not installed in place, and the first limiting rib 22 cannot be engaged in the first limiting groove 14. At this time, if the first limiting rib 22 is provided on the pot body 2, the first limiting rib 22 will support the heating plate 12, so that the pot body 2 will tilt at a large angle relative to the heating plate 12, allowing the user to quickly see that the pot body 2 is not installed in place. If the first limiting rib 22 is located on the bottom shell 10, it will be supported on the bottom wall 20 of the pot. This will cause the pot body 2 to tilt at a larger angle relative to the heating plate 12, allowing the user to quickly see if the pot body 2 is not installed correctly. Therefore, through the cooperation of the first limiting rib 22 and the first limiting groove 14, on the one hand, the installation of the pot body 2 and the heating plate 12 can be repositioned, improving the positioning accuracy of the pot body 2. On the other hand, through the cooperation of the first limiting rib 22 and the first limiting groove 14, the user can more easily discover that the pot body 2 is not installed correctly, so that the user can promptly find out and adjust the installation position of the pot body 2. This ensures the heating effect of the heating plate 12 and improves the user experience.

[0069] In this application, the first limiting rib 22 can also be called the foolproof rib. The first limiting rib 22 can ensure that the pot body 2 can be installed in place, thus achieving the effect of foolproof installation.

[0070] In any of the above embodiments, optionally, as Figures 1 to 6 As shown, the heating base 1 includes a first limiting groove 14, and the pot body 2 includes a first limiting rib 22. The first limiting rib 22 and the bottom wall 20 of the pot are an integral structure.

[0071] In this embodiment, the first limiting groove 14 is disposed on the heating base 1. The pot body 2 is provided with a first limiting rib 22, which can simplify the structure of the pot body 2. The first limiting rib 22 and the pot body 2 are made into an integral structure, or the first limiting rib 22 and the pot body 2 are integrally formed, which can ensure the connection strength between the first limiting rib 22 and the pot body 2.

[0072] In any of the above embodiments, optionally, as Figures 1 to 3As shown, the heating base 1 includes a first limiting groove 14, and the pot body 2 includes a first limiting rib 22. The height dimension of the first limiting rib 22 along the height direction of the pot body 2 is less than or equal to the height dimension of the second limiting rib 24 along the height direction of the pot body 2.

[0073] In this embodiment, when the first limiting rib 22 and the second limiting rib 24 are provided on the pot body 2, the height of the first limiting rib 22 is lower than or level with the second limiting rib 24, so that a supporting plane can be formed by the second limiting rib 24 to facilitate the placement of the pot body 2 on a flat surface such as a stove.

[0074] In any of the above embodiments, optionally, as Figure 1 and Figure 4 As shown, there are one or more second limiting ribs 24. When there are multiple second limiting ribs 24, the multiple second limiting ribs 24 are disposed on the edge of the pot body 2, and the first limiting rib 22 is disposed in the middle of the bottom wall 20 of the pot.

[0075] In this embodiment, multiple second limiting ribs 24 are disposed on the edge of the pot body 2, facilitating the limiting engagement between the second limiting ribs 24 and the edge of the heating plate 12. The first limiting rib 22 is disposed in the middle of the bottom wall 20 of the pot, ensuring that when the pot body 2 is not properly installed, the angle of inclination of the pot body 2 relative to the heating plate 12 is relatively large, making it easier for the user to notice in time. Conversely, if the first limiting rib 22 is disposed on the edge of the pot body 2, the angle of inclination of the pot body 2 relative to the heating plate 12 will be relatively small when the pot body 2 is not properly installed, making it less likely for the user to notice that the pot body 2 is not properly installed.

[0076] The bottom wall 20 of the pot body 2 is elongated, and multiple second limiting ribs 24 are disposed at the four corners of the pot body 2. The first limiting rib 22 is disposed in the middle of the outer bottom wall of the pot body 2.

[0077] In the case of a long, narrow pot body 2, the probability of improper installation is relatively high due to its length. This means that if the long, narrow pot body is not installed correctly, it is particularly difficult to detect. By setting the first limiting rib 22, the tilt angle of the long, narrow pot body after installation is amplified, creating a visually visible assembly step error when the long, narrow pot body is not installed correctly, allowing the user to correct the pot's placement immediately. Therefore, setting the first limiting rib 22 on the long, narrow pot body can significantly improve the situation of improper installation of the long, narrow pot body.

[0078] Of course, in other designs, the pot body 2 can also be a circular pot body.

[0079] In any of the above embodiments, optionally, as Figure 3As shown, the first limiting rib 22 is provided with a first guiding surface 222. The first guiding surface 222 is used to guide the first limiting rib 22 into the first limiting groove 14 when the pot body 2 is installed on the heating plate 12.

[0080] In this embodiment, by setting a first guide surface 222, when the first limiting rib 22 is located near the first limiting groove 14, the first limiting rib 22 can slide into the first limiting groove 14 under the action of the first guide surface 222, thereby increasing the probability of the pot body 2 being installed in place.

[0081] In any of the above embodiments, optionally, the second limiting rib 24 is provided with a second guiding surface, which is used to guide the second limiting rib 24 to be limited to the edge of the heating plate 12 when the pot body 2 is installed on the heating plate 12.

[0082] In this embodiment, by setting a second guide surface, when the second limiting rib 24 is located at the edge of the heating plate 12, the second limiting rib 24 can slide into the edge of the heating plate 12 with the help of the guiding effect of the second guide surface. In this way, the pot body 2 and the heating plate 12 can be guided and installed by the second guide surface during the installation process.

[0083] In any of the above embodiments, optionally, as Figure 3 and Figure 5 As shown, when the pot body 2 and the heating plate 12 are assembled into a working state, a gap is provided between the second limiting rib 24 and the heating plate 12 along the edge to the center direction of the pot body 2.

[0084] In this embodiment, when the pot body 2 and the heating plate 12 are assembled into a working state, a gap is provided between the second limiting rib 24 and the heating plate 12, which makes it easier for the second limiting rib 24 on the edge of the pot body 2 to be engaged with the edge of the heating plate 12, making the installation of the pot body 2 more convenient.

[0085] In any of the above embodiments, optionally, the gap is greater than or equal to 0.5 mm and less than or equal to 3 mm.

[0086] In this embodiment, the gap cannot be set too small. If it is too small, the second limiting rib 24 may interfere with the heating plate 12, affecting the installation of the pot body 2. If the gap is too large, the installation position of the pot body 2 will not be accurate enough, requiring additional adjustment of the installation position, making the installation of the pot body 2 inconvenient. Taking all factors into consideration, setting the gap in the range of 0.5mm-3mm ensures a suitable distance between the second limiting rib 24 and the heating plate 12.

[0087] like Figures 1 to 6As shown, the second aspect of this utility model provides a cooking appliance, including: a heating base 1, the heating base 1 including a heating plate 12 and one of a first limiting groove 14 and a first limiting rib 22; a pot body 2 as in any embodiment of the first aspect; wherein the first limiting rib 22 is located within the first limiting groove 14 when the pot body 2 and the heating plate 12 are assembled in the use state, and is supported on the outer wall surface of the heating plate 12 or the bottom wall 20 of the pot body 2 when the pot body 2 and the heating plate 12 are not in the use state.

[0088] The second aspect of this utility model provides a cooking appliance. Since the cooking appliance provided by this utility model includes the pot body 2 of any embodiment of the first aspect of this utility model, it has all the beneficial effects of the pot body 2 of any embodiment of the first aspect of this utility model.

[0089] In any of the above embodiments, optionally, as Figures 1 to 6 As shown, the heating plate 12 includes two plates 122 spaced apart along a first direction, and the gap between the two plates 122 along the first direction forms a first limiting groove 14.

[0090] In this embodiment, the heating plate 12 is not a single structure, but is composed of multiple plates 122. At least two plates 122 are spaced apart along a first direction, so that a first limiting groove 14 can be formed through the gap between two plates 122, thus simplifying the overall structure of the heating base 1.

[0091] The first direction can be specifically the length direction or the width direction of the pot body 2.

[0092] In any of the above embodiments, optionally, as Figure 6 As shown, the heating base 1 also includes: a bottom shell 10, a heating plate 12 mounted on the bottom shell 10, the heating plate 12 including at least two plates 122; and a plurality of elastic floating components 16 disposed between the plates 122 and the bottom shell 10, so that the plates 122 can float on the bottom shell 10 along the height direction of the heating base 1.

[0093] In this embodiment, the heating base 1 further includes multiple elastic floating components 16, and at least two discs 122 are mounted on the bottom shell 10 for supporting and heating the pot body 2; there can be two to four discs 122, for example, two. Multiple elastic floating components 16 are disposed between each disc 122 and the bottom shell 10, allowing the disc 122 to float up and down under the action of the elastic floating components 16. After the pot body 2 is placed on the heating base 1, the disc 122 descends under the weight of the pot body 2, compressing the elastic element in the elastic floating component 16. This allows the elastic element to apply a rebound force to the disc 122, making the disc 122 and the pot body 2 fit tightly together. This improves the fit between the heating base 1 and the pot body 2 after the pot body 2 is mounted on the heating base 1, thereby improving the heating effect of the disc 122 on the pot body 2.

[0094] This structure, with its multiple plates 122, allows different plates 122 to heat different areas of the pot 2. This separate heating of different areas by the multiple plates 122 achieves zoned heating of the heating base 1, resulting in higher heating efficiency and more uniform heating of each area. Furthermore, the multiple plates 122 provide a basis for zoned temperature control of each area.

[0095] In some embodiments, optionally, at least two disc bodies 122 are arranged independently of each other, and each disc body 122 and the bottom shell 10 are provided with an elastic floating component 16.

[0096] In this embodiment, the disks 122 are completely independently configured, meaning that the different disks 122 are completely separate. Furthermore, each disk 122 and the bottom shell 10 are respectively provided with an elastic floating component 16, meaning that the elastic floating components 16 corresponding to different disks 122 are also completely independently configured. This configuration allows each disk 122 to float independently, without mutual interference between different disks 122. This enables different disks 122 to heat different areas, thus allowing for separate heating of multiple different areas through multiple independent disks 122, thereby achieving zoned heating.

[0097] In some embodiments, optionally, an elastic floating component 16 is provided between each disk body 122 and the bottom shell 10, the elastic floating component 16 being disposed between the middle of the disk body 122 and the bottom shell 10.

[0098] In this embodiment, when the elastic floating component 16 is set to a large size, only one elastic floating component 16 needs to be set. At this time, the elastic floating component 16 can be set between the middle of the disk body 122 and the bottom shell 10, which can reduce the number of elastic floating components 16 used and make it easier to assemble.

[0099] In some embodiments, optionally, at least three elastic floating components 16 are provided between each disc body 122 and the bottom shell 10, and the at least three elastic floating components 16 are provided between the edge of the disc body 122 and the bottom shell 10.

[0100] In this embodiment, considering the difficulty in sourcing materials for large elastic floating components 16, multiple small elastic floating components 16 can be provided on the edge of the pan body 122. This arrangement makes it easier to source materials and helps maintain the balance of the pan body 122, especially when the pot body 2 is not placed on an uneven surface. The pan body 122 can be set at different angles to follow the pot body 2, ensuring that the pan body 122 and the pot body 2 can always fit together at different angles. Optionally, there can be 3, 4, or 5 elastic floating components 16, and the central angles of any two adjacent elastic floating components 16 are the same.

[0101] In some embodiments, optionally, such as Figure 5 As shown, the heating plate 12 includes at least two plate bodies 122, and the edge of the plate body 122 is provided with a first chamfer 1222 to guide the first limiting rib 22, and / or the edge of the plate body 122 is provided with a second chamfer 1224 to guide the second limiting rib 24.

[0102] In this embodiment, when the heating plate 12 is composed of at least two plate bodies 122, a second chamfer 1224 is provided on the edge of the plate body 122. The second limiting rib 24 can move along the second chamfer 1224, thereby guiding the second limiting rib 24 and thus achieving installation guidance between the pot body 2 and the plate body 122. A first chamfer 1222 is provided on the edge of the plate body 122. The first limiting rib 22 can move along the first chamfer 1222, thereby guiding the first limiting rib 22 into the first limiting groove 14. The guidance of the first chamfer 1222 and / or the second chamfer 1224 makes the installation of the pot body 2 smoother and more convenient.

[0103] In some embodiments, the cooking appliance may optionally include at least one of a multi-cooker, an electric pressure cooker, and a rice cooker.

[0104] In some embodiments, the heating base 1 may optionally include: at least two thermostats mounted on the base shell 10, corresponding one-to-one with at least two plates 122, for detecting the temperature of the pot body 2 and / or the corresponding plate 122; and a control device for controlling the operation of the corresponding plate 122 according to the temperature detected by each thermostat.

[0105] In this embodiment, at least two thermostats are installed on the bottom shell 10, corresponding one-to-one with at least two plates 122. That is, the number of plates 122 is the same as the number of thermostats. Each thermostat can detect the temperature of the pot body 2 and / or its corresponding plate 122. The control device is used to control the operation of its corresponding plate 122 according to the temperature detected by each thermostat, thereby realizing independent control of each plate 122. In this way, the heating power and start / stop of each plate 122 can be controlled separately according to actual needs, so that the heating temperature of different areas of the pot body 2 can be controlled separately.

[0106] In some embodiments, optionally, the pan body 122 is provided with clearance holes, and at least two thermostats are respectively provided at the clearance holes of at least two pan bodies 122, and at least a part of each thermostat can extend into the corresponding clearance hole and contact the pot body 2 to detect the temperature of the pot body 2.

[0107] In this embodiment, each plate 122 is provided with a clearance hole, and at least a portion of the thermostat can extend into the clearance hole and contact the pot 2 to detect the temperature of the pot 2. This design allows the thermostat to directly detect the temperature of the pot 2 and then control the operation of each plate 122 based on that temperature. This enables zoned heating control of the pot 2 based on the temperature of different areas of the pot 2. Directly detecting the temperature of the pot 2 to control the operation of the plate 122 allows for more precise temperature control. Of course, in other embodiments, the thermostat can also directly detect the temperature of different areas of the plate 122 and then control the temperature of different plates 122 based on the temperature of those areas.

[0108] In some embodiments, at least two discs 122 may have the same shape.

[0109] In this embodiment, at least two disks 122 have the same shape, so only one specification of disk 122 needs to be designed, resulting in faster manufacturing efficiency. Of course, depending on the requirements, the shapes of at least two disks 122 can also be different. In the actual production process, the shape of the corresponding disk 122 can be designed according to different needs.

[0110] In some embodiments, the disk body 122 may optionally be at least one of a square disk, a circular disk, or an elliptical disk. The shape of the disk body 122 may be selected as needed, and may be square, circular, or elliptical, but is not limited to these shapes.

[0111] Optionally, each plate 122 includes a heat-conducting plate and a heating element, with the heating element mounted on the back of the heat-conducting plate. The front of the plate 122 is used to contact the pot body 2 to heat and support the pot body 2.

[0112] The pot body 2 and cooking utensils in this application will be described below in conjunction with a double-plate electric heater (such as an electric hot pot).

[0113] In related solutions, dual-disc electric heaters using heating plates typically employ two types of limiting mechanisms:

[0114] The first type is: the base contacts the outer wall of the pot for positioning, which is more accurate, but long-term collisions can easily damage the appearance of the pot (mainly the coating on the side wall of the pot).

[0115] The second method is to set a short rib on the bottom wall 20 of the pot, which limits the pot body 2 and the heating plate. With this limiting method, the pot body 2 moves a lot in the horizontal direction, and the user cannot easily notice when the pot body 2 is not in place, which results in poor heating effect and poor user experience.

[0116] Therefore, how to design an electric heating pot that is accurate in positioning, does not easily damage the appearance of the product, and has a good heating effect has become an urgent problem to be solved.

[0117] This embodiment aims to provide a pot bottom limiting solution that does not damage the appearance during use, is easy to place, and is easy to detect if it is not placed in place, thus preventing mistake-proofing.

[0118] The limiting scheme provided in this embodiment offers a large assembly tolerance during placement, thanks to the cooperation between the bottom limiting ribs and the heating plate guide. When the tolerance fails, the anti-misalignment ribs create a visually visible and easily detectable assembly step error, allowing the user to correct the placement immediately.

[0119] like Figures 1 to 6 As shown, this embodiment relates to a novel electric heater pot bottom limiting structure, including: a pot (pot body 2): the pot body to be limited by four corner limiting ribs (second limiting ribs 24): responsible for limiting four degrees of freedom on the horizontal plane; limiting rib guide angle: guiding during placement; middle anti-misalignment rib (first limiting rib 22): causing a large assembly error step between the pot and the heating plate (heating plate 12) when the placement is off-center; middle anti-misalignment rib guide angle: guiding during placement; heating plate (heating plate 12): bearing the weight, placing the pot on it; heating plate guide angle: cooperating with the four corner limiting ribs for guidance during placement.

[0120] in, Figure 1 and Figure 2 The diagram shows the relative positional relationship between the bottom limiting structure and the heating plate when the pot body 2 is normally installed on the heating base 1. At this time, the four corner limiting ribs and the middle rib are together locked at the upper limit of the heating plate, with the four corners playing the main limiting role. The gap between the four corner limiting ribs and the heating plate is about 0.5mm to 3mm.

[0121] Figure 4 and Figure 5In the middle, the heating plate has a chamfer around its entire circumference as a guide, and the surfaces of the anti-fooling ribs and limiting ribs that contact the heating plate have an increased slope for guidance.

[0122] Figure 4 and Figure 5 If the pot is not placed correctly, the gap between the pot and the heating plate will be large due to the presence of the anti-fooling rib, and the pot will be unstable. Users can easily find that the pot is not in the right position and can quickly correct its placement.

[0123] The combined action of the four corner limiting ribs and the central anti-misplacement rib ensures smooth and stable placement of the pot body 2. Incorrect placement can be quickly detected and corrected. The anti-misplacement ribs further enhance the installation effect of the pot body 2. This provides a pot bottom structure that does not damage the appearance during use, is easy to place, and is easily detected in case of misplacement, thus preventing mistaken placement.

[0124] The number of limiting ribs and anti-mistake ribs can be varied, and their positions can be selected according to actual needs, such as the edge and middle of the heating plate.
