[0041] In related technologies, cooking appliances with panel structures, such as induction cookers, typically have flat or concave panels. However, this single flat or concave design usually only fits a single type of flat-bottomed or round-bottomed pan, limiting its compatibility with various types of cookware. Furthermore, in the past, panels were usually made of microcrystalline panels, which were relatively expensive.

[0042] The main purpose of this utility model is to propose a cooking appliance that aims to at least solve the technical problem in the related art that the panel is difficult to adapt to different types of cookware.

[0043] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the cooking appliance 100 includes a main body and a panel structure 3. The main body includes a base 1 and an upper cover 2 disposed on the upper end of the base 1. The upper cover 2 has a first through hole 21. The panel structure 3 is disposed on the upper side of the upper cover 2. The panel structure 3 includes a ceramic plate 31 covering the first through hole 21. A groove 311 is provided in the middle of the upper end surface of the ceramic plate 31. The groove 311 extends at least three spaced extension grooves 312 to the periphery of the ceramic plate 31.

[0044] In the technical solution of this utility model, the cooking utensil 100 includes a main body and a panel structure 3. The main body includes a base 1 and an upper cover 2 disposed on the upper end of the base 1. The upper cover 2 has a first through hole 21. The panel structure 3 is disposed on the upper side of the upper cover 2. The panel structure 3 includes a ceramic plate 31 covering the first through hole 21. A groove 311 is provided in the middle of the upper end surface of the ceramic plate 31. The groove 311 extends at least three spaced extension grooves 312 to the periphery of the ceramic plate 31. The ceramic plate 31 is used to place cookware. Taking advantage of the high plasticity of the ceramic plate 31, the groove 311 and at least three extension grooves 312 are provided on the ceramic plate 31. When a round-bottomed pot is to be placed, the center of the bottom of the round-bottomed pot can be accommodated by the groove 311, while the sides of the three extension grooves 312 can provide three-point support for other parts of the bottom of the round-bottomed pot, maintaining the stability of the round-bottomed pot. When a flat-bottomed pot is to be placed, the part of the upper surface of the ceramic plate 31 outside the groove 311 and the at least three extension grooves 312 can also stably support the flat-bottomed pot. With this configuration, the panel structure 3 of the cooking utensil 100 can be adapted to different types of cookware, while the cost of the ceramic plate 31 is low.

[0045] The cooking appliance 100 also includes a heating element 6, which is disposed on the base 1 corresponding to the first through hole 21, for heating the pot placed on the ceramic plate 31. The heating element 6 can take various forms, such as electromagnetic heating or resistance heating.

[0046] The cooking appliance 100 includes an induction cooker or an electric ceramic cooker.

[0047] During the use of the cooking appliance 100, it is necessary to continuously measure the temperature of the bottom of the pot in order to accurately control the heating power, keep the temperature of the bottom of the pot stable, and promptly detect any abnormal rise in the temperature of the bottom of the pot, so as to stop heating immediately and avoid damage to the pot due to dry burning or even causing a safety accident. Therefore, the cooking appliance 100 also includes a temperature sensing element 7, the temperature sensing end of the temperature sensing element 7 abutting against the lower end surface of the ceramic plate 31, so as to sense the temperature of the bottom of the pot through the temperature of the ceramic plate 31.

[0048] It is understandable that the ceramic plate 31 needs to have a considerable thickness because its upper surface needs to have the groove 311 and the at least three extension grooves 312. If the ceramic plate 31 is too thick, the distance between the temperature sensing element 7 and the bottom of the pot will be relatively large, resulting in a deviation between the temperature detected by the temperature sensing element 7 and the actual temperature of the pot. The response time to temperature changes will also be longer, which may make it impossible for the cooking utensil 100 to accurately control the temperature and affect the cooking quality of the food.

[0049] To enable the temperature sensing element 7 to more accurately measure the temperature of the pot bottom, please refer to the embodiments of this utility model. Figure 1 , Figure 3 , Figure 5 and Figure 7 The cooking appliance 100 also includes at least one temperature sensing element 7, the upper end of which is a temperature sensing end, and the lower end surface of the ceramic plate 31 is provided with a receiving groove 315 adapted to the temperature sensing end. Thus, by providing the receiving groove, the distance between the ceramic plate 31 and the bottom of the pot is shortened, thereby reducing the response time to temperature changes, reducing the deviation between the detected temperature and the actual temperature of the pot, and improving the accuracy of temperature control by the cooking appliance 100.

[0050] If the temperature sensing end of the temperature sensing element 7 is only in direct contact with the lower end surface of the ceramic plate 31, the ceramic plate 31 may undergo slight deformation due to high temperature during use, which may lead to the temperature sensing end of the temperature sensing element 7 separating from the lower end surface of the ceramic plate 31. The accommodating groove 315 can also play a positioning role. Even if the ceramic plate 31 deforms, it can keep the temperature sensing end of the temperature sensing element 7 in the accommodating groove 315, reducing the possibility of the temperature sensing element 7 separating from the lower end surface of the ceramic plate 31.

[0051] The temperature sensing element 7 can be provided as one or more. In order to further reduce the risk of the temperature sensing element 7 separating from the ceramic plate 31, it is preferable to provide multiple temperature sensing elements 7, and the corresponding receiving groove 315 is also provided as multiple. In this way, even if one temperature sensing element 7 separates from the ceramic plate 31, the temperature of the bottom of the pot can be detected by the other temperature sensing element 7. The possibility of multiple temperature sensing elements 7 separating from the ceramic plate 31 at the same time is very small.

[0052] The ceramic plate 31 provides different support for different cookware. For flat-bottomed pots, it supports the portion of the ceramic plate 31 outside the groove 311 and the extension groove 312. For round-bottomed pots, it supports the portion through the side wall of the extension groove 312. If the receiving groove 315 is located on a flat surface, the distance between the temperature sensing element 7 and the round-bottomed pot will be greater. If the receiving groove 315 is located on the extension groove 312, the distance between the temperature sensing element 7 and the flat-bottomed pot will be greater. To ensure accurate temperature measurement for both round-bottomed and flat-bottomed pots, in this embodiment, the receiving groove 315 is located at the junction of the extension groove 312 and other parts of the ceramic plate 31. This arrangement ensures that the distance between the temperature sensing element 7 and the cookware is relatively close, regardless of whether a flat-bottomed or round-bottomed pot is used, guaranteeing accurate temperature measurement for different types of cookware.

[0053] For details, please refer to Figure 5 and Figure 7 The temperature measuring element 7 is disposed on the base 1, and the heating element 6 is provided with a clearance part. The upper end of the temperature measuring element 7 passes through the clearance part into the receiving groove 315.

[0054] Because the ceramic plate 31 is opaque, there are certain difficulties in assembling the ceramic plate 31 and the upper cover 2. Therefore, in this embodiment, please refer to... Figure 3 and Figure 4 The cooking appliance 100 also includes a positioning structure 4, which includes a positioning groove 41 and a positioning protrusion 42 that cooperate in the vertical direction. One of the positioning groove 41 and the positioning protrusion 42 is disposed on the ceramic plate 31, and the other is disposed on the upper cover 2.

[0055] In the technical solution of this embodiment, the ceramic plate 31 is made of highly malleable. The positioning groove 41 or the positioning protrusion 42 is provided on the ceramic plate 31. In this way, it can cooperate with the corresponding positioning structure 4 on the upper cover 2 during assembly. The positioning between the ceramic plate 31 and the upper cover 2 can be achieved simply by aligning the positioning protrusion 42 and the positioning groove 41 in the vertical direction, thereby improving the convenience of assembly.

[0056] It should be noted that "one of the positioning groove 41 and the positioning protrusion 42 is disposed on the ceramic plate 31 and the other is disposed on the upper cover 2" includes two parallel schemes. One is that the positioning groove 41 is disposed on the ceramic plate 31 and the positioning groove 41 is disposed on the upper cover 2. The other is that the positioning groove 41 is disposed on the upper cover 2 and the positioning protrusion 42 is disposed on the ceramic plate 31.

[0057] The positioning groove 41 can be directly formed on the upper cover 2 or the ceramic plate 31, or it can be formed by providing at least two protrusions on the upper cover 2 or the ceramic plate 31. It is understood that to ensure the stability of the assembly of the ceramic plate 31 and the upper cover 2, the mating dimensions in the vertical direction need to be guaranteed. If the groove is directly formed on the upper cover 2, the overall thickness of the upper cover 2 needs to be relatively large. Consequently, with a fixed internal space, the overall height of the cooking appliance 100 will be larger, which is not conducive to a thin and light design. On the other hand, if the groove is directly formed on the ceramic plate 31, it is more difficult and can easily damage the ceramic plate 31.

[0058] Therefore, in this embodiment of the present invention, two protrusions 22 are provided at intervals on the upper side of the upper cover 2, and the interval between the two protrusions 22 defines the positioning groove 41; thus, the overall thickness of the upper cover 2 does not need to be thick, only to ensure its supporting function for the panel structure 3, and the two protrusions 22 and the upper cover 2 can be directly injection molded as a whole, which is convenient for production.

[0059] There are various ways in which the two protrusions 22 can be distributed. In some embodiments, the two protrusions 22 can be distributed radially along the first through hole 21 or circumferentially along the first through hole 21.

[0060] In a further embodiment, the outer periphery of the ceramic plate 31 is provided with a downwardly extending first flange portion 313, and the positioning protrusion 42 is provided on the inner side of the first flange portion 313; the upper side of the upper cover 2 is provided with two protrusions 22 spaced apart circumferentially along the first through hole 21, and the interval between the two protrusions 22 defines the positioning groove 41. In the technical solution of this embodiment, the two protrusions 22 are distributed circumferentially along the first through hole 21. When positioning the ceramic plate 31 and the upper cover 2, it will not affect the direct insertion of the positioning protrusion 42 between the two protrusions 22, and it can also limit the rotation of the ceramic plate 31 during the installation process, making the assembly of the ceramic plate 31 more convenient; at the same time, when the ceramic plate 31 moves in the horizontal direction, the two protrusions 22 of the first flange portion 313 will also come into contact, that is, the cooperation between the two protrusions 22 and the first flange portion 313 can further limit the movement of the ceramic plate 31 after positioning.

[0061] To further improve the stability of the fit between the positioning protrusion 42 and the positioning groove 41, please refer to... Figure 3 and Figure 4The positioning structure 4 further includes a stop portion 43 protruding from the upper side of the upper cover 2. The stop portion 43 abuts against the side of the positioning protrusion 42 away from the first flange portion 313. The stop portion 43 allows the structural features on the upper cover 2 to limit the positioning protrusion 22 in more directions, ensuring that the ceramic plate 31 is well positioned in all directions after the positioning protrusion 42 is inserted into the positioning groove 41, facilitating assembly.

[0062] The stop portion 43 and the two protrusions 22 can be separately arranged or integrally arranged. In this embodiment of the present invention, the stop portion 43 and the two protrusions 22 are integrally arranged. This arrangement allows the two protrusions 22 to be connected together by the stop portion 43, which improves the strength of each individual stop portion 43 and each individual protrusion 22, and also makes manufacturing easier.

[0063] It should be noted that the protrusion 22 and the stop 43 can be separately manufactured from the upper cover 2 and then fixed to the upper cover 2, or they can be integrally formed with the upper cover 2. Regardless of the forming method, connecting the two protrusions 22 together through the stop 43 makes processing more convenient. For example, when the two protrusions 22 and the stop 43 are separate from the upper cover 2, they can be formed into a single component in one step and then installed. When integrally formed, the two protrusions 22, the stop 43, and the upper cover 2 can be formed directly in one step, ensuring the relative positional relationship between the two protrusions 22 and the stop 43 and reducing the need for subsequent adjustments.

[0064] It is understandable that when there is only one positioning groove 41 and one positioning protrusion 42, the positioning effect on the upper cover 2 and the ceramic plate 31 is poor. Therefore, in the embodiments of this utility model, multiple positioning grooves 41 are provided, and multiple positioning protrusions 42 are provided accordingly.

[0065] Specifically, in this embodiment, the plurality of positioning protrusions 42 are arranged in a ring along the inner periphery of the first flange portion 313, and the positioning grooves 41 are arranged in a ring along the periphery of the first through hole 21.

[0066] Furthermore, the stop portion 43 is also provided with various types corresponding to the positioning groove 41.

[0067] It is understood that the positioning protrusion 42 and the positioning groove 41 are not tightly locked together. After the positioning protrusion 42 is inserted into the positioning groove 41, there is a certain gap between it and the side wall of the positioning groove 41. Otherwise, no matter which one of the positioning protrusion 42 and the positioning groove 41 is set on the ceramic plate 31, the ceramic plate 31 is easily damaged during the locking process. That is, the positioning structure 4 only serves to position the ceramic plate 31 and the upper cover 2, and does not serve to fix them.

[0068] To secure the ceramic plate 31 and the top cover 2, they can be fixed using tape or glue. It is understood that tape generally has lower heat resistance than glue, and the cooking appliance 100 generates high temperatures during use; therefore, glue is preferred for securing the ceramic plate 31 and the top cover 2.

[0069] There are several options for the bonding location between the ceramic plate 31 and the upper cover 2. It can be achieved by directly applying adhesive between the positioning groove 41 and the positioning protrusion 42, or by using other locations. However, the contact area between a single positioning groove 41 and the positioning protrusion 42 is limited. Even if multiple positioning grooves 41 and positioning protrusions 42 are provided, the overall bonding area between the ceramic plate 31 and the upper cover 2 remains small, potentially leading to instability.

[0070] Therefore, in this embodiment of the invention, the outer periphery of the ceramic plate 31 is provided with a downwardly extending first flange portion 313, which is bonded to the upper cover 2. This arrangement ensures a sufficient bonding area while also improving the sealing between the ceramic plate 31 and the upper cover 2, thereby reducing the possibility of external impurities entering the cooking appliance 100 through the first through hole 21 from the gap between the ceramic plate 31 and the upper cover 2.

[0071] Furthermore, an adhesive groove can be provided between the first flange 313 and the upper cover 2 to improve the bonding effect. The adhesive groove can be located at the lower end of the first flange 313 or on the upper side of the upper cover 2. It is understood that although the ceramic plate 31 has the characteristic of being able to be made into irregular shapes, it is relatively brittle. Placing the adhesive groove on the first flange 313 would undoubtedly greatly increase the processing difficulty and cost. Moreover, when fixing with adhesive, the ceramic plate 31 must be turned upside down and placed on the bottom, which is inconvenient. Therefore, in the embodiments of this utility model, please refer to... Figure 5 and Figure 6 The glue tank is placed on the upper side of the upper cover 2.

[0072] The panel structure 3 can use the ceramic plate 31 as a whole to completely cover the top cover 2, or it can be divided into sections. It is understood that the cookware is placed on the ceramic plate 31 at the position corresponding to the first through hole 21. The temperature of the panel structure 3 is the highest at this position, that is, the ceramic plate 31 at this position needs to have sufficient high temperature resistance. If the panel structure 3 uses the ceramic plate 31 as a whole, it means that the entire panel structure 3 has sufficient high temperature resistance, which will result in a higher cost for the entire panel structure 3.

[0073] Therefore, in this embodiment, the panel structure 3 further includes a second panel 32, the second panel 32 having a second through hole 321 corresponding to the first through hole 21 in its center; the ceramic plate 31 covers the second through hole 321, and its upper end protrudes from the second panel 32. With this configuration, the panel structure 3 adopts a combination of the ceramic plate 31 and the second panel 32. This allows only the ceramic plate 31 to be made of a material with high temperature resistance, while the second panel 32, which does not need to withstand very high temperatures, can be made of a material with relatively weaker temperature resistance and lower cost, thereby reducing the overall cost of the panel structure 3.

[0074] The second panel 32 can be made of tempered glass or ceramic. It should be noted that when the second panel 32 is made of ceramic, a material with lower high-temperature resistance than the ceramic plate 31 can be selected for better cost-effectiveness.

[0075] There are various arrangements of the second panel 32 and the ceramic plate 31. In one embodiment, please refer to... Figure 8 The second panel 32 is fitted onto the outer periphery of the ceramic plate 31. When installing the second panel 32, after positioning the ceramic plate 31 and the upper cover 2 using the positioning structure 4, the second panel 32 is directly fitted onto the ceramic plate 31 through the second through hole 321 to complete the positioning. Then, it can be fixed to the upper cover 2 with glue. In one embodiment, please refer to... Figure 6 The lower end of the ceramic plate 31 covers the second through hole 321. This arrangement changes the upward-opening gap between the ceramic plate 31 and the second panel 32 into an opening facing the horizontal direction, making the overall structure more aesthetically pleasing and reducing the phenomenon of dust accumulation.

[0076] When the lower end of the ceramic plate 31 covers the second through hole 321, in order to position the second panel 32, an annular groove adapted to the second panel 32 can be opened on the upper side of the upper cover 2; during assembly, the second panel 32 is first positioned by the annular groove, and then fixed by glue, and then the ceramic plate 31 is positioned and fixed by the positioning structure 4.

[0077] As described above, the positioning protrusion 42 and the positioning groove 41 are not tightly locked together. After the positioning protrusion 42 is inserted into the positioning groove 41, there is a certain gap between it and the side wall of the positioning groove 41. That is, when the ceramic plate 31 and the upper cover 2 are positioned by the positioning structure 4, the ceramic plate 31 can still move in the vertical direction. During the process of fixing with glue, the ceramic plate 31 may be at risk of shifting. Therefore, in this embodiment, the cooking appliance 100 also includes a limiting structure 5. The limiting structure 5 includes a limiting groove 51 and a limiting protrusion 52 arranged in the horizontal direction. The limiting groove 51 and the limiting protrusion 52 cooperate to restrict the vertical movement of the ceramic plate 31. One of the limiting groove 51 and the limiting protrusion 52 is provided on the ceramic plate 31, and the other is provided between the upper cover 2 or the upper cover 2 and the second panel 32. Thus, the vertical movement of the ceramic plate 31 is restricted by the limiting groove 51 and the limiting protrusion 52 that cooperate in the horizontal direction, so as to ensure the stability of the ceramic plate 31 during assembly.

[0078] In one specific embodiment, please refer to Figure 9 The ceramic plate 31 has a downwardly extending first flange 313 on its outer periphery, and a second flange 314 extending outwardly at the lower end of the first flange 313. The limiting protrusion 52 includes the second flange 314. The upper side of the upper cover 2 and the lower side of the second panel 32 are at least partially spaced apart to form the limiting groove 51. In this embodiment, when assembling the ceramic plate 31, the ceramic plate 31 and the upper cover 2 are first positioned horizontally by the positioning structure 4. Then, the second panel 32 is sleeved on the outside of the ceramic plate 31, and the second flange 314 of the ceramic plate 31 is pressed tightly. This allows the second panel 32 and the upper cover 2 to clamp the ceramic plate 31 vertically, achieving vertical limiting.

[0079] The phrase "at least partially spaced between the upper side of the top cover 2 and the lower side of the second panel 32" means that the second panel 32 and the top cover 2 can be completely spaced apart, or only partially spaced apart. When the second panel 32 and the top cover 2 are completely spaced apart, additional supports need to be filled between them to fix them, which is inconvenient in practice and provides poor support for the second panel 32. Therefore, in this embodiment, the upper side of the top cover 2 is provided with a receiving groove adapted to the second flange 314, and the limiting groove 51 includes the receiving groove. In this way, the second flange 314 is accommodated by the receiving groove, allowing the second panel 32 to be directly placed on the top cover 2, making fixation more convenient and the support more stable.

[0080] In yet another specific embodiment, please refer to Figure 10 The ceramic plate 31 has a downwardly extending first flange 313 on its outer periphery, and a second flange 314 extending outwardly at the lower end of the first flange 313. The limiting protrusion 52 includes the second flange 314, and the limiting groove 51 is disposed on the upper cover 2. It should be noted that when the ceramic plate 31 is limited vertically in this way, the limiting groove 51 can be a protruding feature disposed on the upper side of the upper cover 2, or it can be implemented by a separate injection molding part, which is fixed to the upper side of the upper cover 2 when the ceramic plate 31 is installed.

[0081] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
