[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0052] This utility model provides a cooking stove with a weighing function, which can weigh the cooking pot and the ingredients inside the cooking pot during the cooking process. Users can judge the cooking progress and cooking effect of the ingredients based on the weighing results and changes in the weighing data during the cooking process.

[0053] See Figure 1 , Figures 3-4 , Figures 12-15 ,as well as Figures 19-21The cooking stove of this utility model includes a stove body, a weighing component 40, and a heating component 51. The stove body includes a panel 10, a cooking plate 20, and a stove cavity 24 formed by the panel 10 and the cooking plate 20 fixedly connected and enclosed. The stove body also has a heat exhaust hole 23 connecting the stove cavity 24 and the outside of the stove body. The panel 10 includes an upper side and a lower side arranged opposite to each other. The upper side is the side of the panel 10 that is away from the cooking plate 20 and the stove cavity 24, and the lower side is the side of the panel 10 that is relatively close to the cooking plate 20. The panel 10 has a through hole 11 that passes through the upper side and the lower side, and the upper side has a stop edge 61 protruding around the outer periphery of the edge of the through hole 11. The heating component 51 is disposed in the stove cavity 24 and is used to heat the cooking pot. The weighing component 40 includes a sensing component 41, a support component 42, and a stop cap 43. The sensing component 41 is located on the side of the panel 10 that is away from the upper side. The sensing component 41 is accommodated in the stove cavity 24 by the stove body. The support member 42 passes through the through hole 11 and its two ends protrude from the upper and lower sides of the panel 10, respectively. The end of the support member 42 protruding from the upper side of the panel 10 is used to support the cooking pot, and the other end of the support member 42 protruding from the lower side of the panel 10 forms the assembly end 421 for connecting the sensing element 41. The support member 42 extends from the upper side of the panel 10 and is surrounded by the stop edge 61. The support member 42 does not contact the hole wall of the through hole 11 or the inner peripheral side of the stop edge 61, that is, the support member 42 does not contact the panel 10 or the stop edge 61. The stop cap 43 includes a cap ring 431 surrounding the outer peripheral side of the stop edge 61. The stop edge 61 has a hollow cylindrical or prismatic structure. The inner peripheral side of the stop edge 61 is the side of the stop edge 61 that is relatively close to the outer peripheral wall of the support member 42, and the outer peripheral side of the stop edge 61 is the other side of the stop edge 61 that is opposite to the outer peripheral wall of the support member 42.

[0054] Specifically, the support member 42 is used to bear the pressure of the cooking pot and the food inside the cooking pot and transfer the load to the sensing member 41. The sensing member 41, under the loading action of the support member 42, will generate stress or strain changes associated with the load. The specific changes depend on the type of sensing member 41. The stress or strain value of the sensing member 41 has a proportional relationship with the weight of the cooking pot and the food, thus characterizing the weight of the cooking pot and the food. The sensing member 41 is located in the stove cavity 24, which on the one hand achieves reasonable utilization of the space in the stove cavity 24 and avoids wasting space; on the other hand, the sensing member 41 being located inside the stove cavity 24 does not increase the overall thickness of the cooking stove. The overall thickness is measured along the stacking direction of the panel 10 and the stove plate 20. Since the cooking pot is located on the side of the panel 10 facing away from the bottom, a through hole 11 must be opened in the panel 10 for the support member 42 to extend out of the panel 10. The opening of the through hole 11 should not be too small, otherwise the contact between the support member 42 and the panel 10 will cause distortion of the weighing results. In actual use, the broth, Liquids such as residual water droplets from food can easily leak into the stove cavity 24 through the through hole 11. The sensing element 41 and the heating element 51 are very susceptible to moisture and may malfunction. The stop edge 61 protruding from the upper side of the panel 10 can prevent liquid from entering the through hole 11, thereby protecting the sensing element 41 and the heating element 51 from contact with liquid to a certain extent. However, the height of the stop edge 61 protruding from the upper side of the panel 10 is ultimately limited to ensure that the stop edge 61 does not contact the cooking pot. Therefore, the effect of the stop edge 61 in blocking liquid is limited. The cap 43 surrounds the stop edge 61 with the cap ring 431, thereby preventing liquid from approaching the through hole 11 and the stop edge 61.

[0055] In some embodiments, the cooking stove also includes a pot rack 70 located on the side of the panel 10 facing away from the bottom. The pot rack 70 supports the bottom of the cooking pot. A support member 42 protrudes from the upper side of the panel 10, supporting the pot rack 70 and lifting it away from the upper side of the panel 10. The overall thickness of the cooking stove is the distance from the pot rack 70 to the bottom of the cooktop 20, where the bottom of the cooktop 20 is the side of the cooktop 20 facing away from the panel 10. With this arrangement, the panel 10 does not share the weight of the pot rack 70, the cooking pot, and the food, thus ensuring the accuracy of the weighing result of the weighing member 40. Optionally, see [reference needed]. Figures 4-5 , Figures 14-15 , Figures 20-22 The pot rack 70, the panel 10, and the stove plate 20 are stacked vertically and arranged close to the ground. The overall thickness is measured in the direction of the thickness of the panel 10. The panel 10 is a horizontally extending plate structure, and the axis of the support member 42 is a vertical straight line. It can be understood that in other embodiments, the pot rack 70 may be omitted, and the cooking pot may be directly supported by the support member 42.

[0056] Compared to existing cooktops that place the pressure-sensitive module (sensor 41) at the bottom of the cooktop body, this invention avoids the increased thickness caused by placing the sensor 41 at the bottom of the cooktop plate 20. The overall structure of this cooktop is more flat and compact, controlling the overall thickness without increasing the thickness due to the addition of the sensor 41 and weighing function. Therefore, this cooktop is more easily adapted to conventional countertops, expanding its installation options and avoiding the need for separate countertop designs for cooktops with larger overall thicknesses. The sensor 41 is enclosed within the cooktop cavity 24 by the panel 10 and the cooktop plate 20. To better protect the sensor 41 from external impacts, the heat dissipation hole 23 allows airflow exchange between the stove cavity 24 and the outside of the stove body, so that the airflow can carry away the heat in the stove cavity 24 and prevent heat from accumulating in the stove cavity 24 for a long time, thus reducing the risk of the sensor 41 malfunctioning due to heat. In addition, based on the use of the stop edge 61 to prevent liquid from flowing into the through hole 11, the baffle 43 around the stop edge 61 can further prevent liquid from approaching the through hole 11 and the stop edge 61, making it less likely for liquid to flow along the support 42 to the sensor 41, thereby providing the sensor 41 with more effective waterproof protection. Users do not need to worry about liquid leaking into the stove cavity 24 during cooking.

[0057] See Figures 4-5 , Figures 15-16 , Figure 22 A first anti-contact gap is formed between the outer peripheral side of the support member 42 and the wall of the through hole 11. A second anti-contact gap is formed between the outer peripheral side of the support member 42 and the inner peripheral side of the stop edge 61 surrounding the support member 42. Both the first and second anti-contact gaps provide radial movement space for the support member 42 to allow the support member 42 to move slightly relative to the panel 10 after being subjected to force, and to ensure that the support member 42 never contacts the panel 10 and the stop edge 61. Optionally, see [reference needed]. Figure 1 , Figures 3-4 , Figure 7 , Figures 12-15 , Figures 19-21 In some embodiments, the cooking stove also includes a liquid collection tray 60, which includes a cover 63 and a stop edge 61. The cover 63 is positioned on the upper side of the panel 10, and the stop edge 61 protrudes from the side of the cover 63 facing away from the panel 10. The cover 63 has a surrounding hole 62, and the inner periphery of the stop edge 61 forms a liquid collection channel communicating with the surrounding hole 62. The support member 42 passes through the liquid collection channel and protrudes from the end of the stop edge 61 that is relatively far away from the panel 10. The liquid collection tray 60 and the upper side of the panel 10 form a step, which further increases the difficulty of liquid leakage into the liquid collection channel and optimizes the effect of the stop edge 61 in blocking liquid. In other embodiments, the cover 63 can be omitted, and the stop edge 61 protrudes directly from the upper side of the panel 10.

[0058] Furthermore, the cap 43 is fixedly connected to the support member 42. The cap 43 also includes a cover 432, which is located at the end of the support member 42 that is relatively far from the assembly end 421 and the sensing element 41. (See reference...) Figures 15-16 The cover 432 extends radially outward along the support member 42. One end of the cap ring 431 is bent and connected to the outer periphery of the cover 432. The other end of the cap ring 431 forms a pressure-resistant gap with the upper side of the panel 10. This arrangement ensures that the cap 43 does not contact the panel 10. The pressure-resistant gap provides axial movement space for the support member 42, allowing the support member 42 to sink slightly under the pressure of the cooking pot and food. The cover 432, cap ring 431, and support member 42 together form an opening facing the panel 10. The cap cavity 433 has a stop edge 61 extending into it at one end, away from the panel 10. A third anti-contact gap is formed between the outer periphery of the stop edge 61 and the inner periphery of the cap ring 431. The inner periphery of the cap ring 431 is the side of the cap ring 431 closest to the stop edge 61 and the straight rod portion of the support member 42. This third anti-contact gap provides radial movement space for the support member 42, allowing it to move slightly relative to the panel 10 under force, thus ensuring that the cap 43 and the stop edge 61 do not come into contact with each other. (See also...) Figures 5-6 , Figures 15-16 The end of the stop edge 61 extending into the cap cavity 433 forms an anti-collision gap with the side of the cover 432 facing the panel 10. This anti-collision gap provides axial movement space for the support member 42, allowing it to sink slightly under the pressure of the cooking pot and food. With this configuration, when the support member 42 is subjected to the load of the food and cooking pot, regardless of whether the support member 42 moves slightly in the radial or axial direction, the cover 43 will not contact the panel 10 and the stop edge 61. Neither the panel 10 nor the stop edge 61 will share the weight of the food and cooking pot, thus ensuring the accurate weighing results of the food and cooking pot.

[0059] See Figure 6 , Figure 16 The stove cavity 24, through hole 11, surrounding hole 62, cap cavity 433, and the outside of the stove body are connected to form a venting channel, allowing heat from the stove cavity 24 to be discharged from the stove body sequentially through hole 11, surrounding hole 62, and cap cavity 433. The end of the stop edge 61, which is relatively far from the panel 10, extends into the cap cavity 433, making the venting channel more meandering and increasing the difficulty of liquid leakage into the stove cavity 24 along the venting channel. This can simultaneously ensure the outward flow of heat from the stove cavity 24 and prevent liquid leakage. In addition to the cap ring 431 surrounding the stop edge 61, the cap 43, through the cover 432, vertically blocks the stop edge 61 and surrounding hole 62, preventing soup that overflows to the bottom wall of the cooking pot during cooking from directly entering the surrounding hole 62. The overflowing soup at most flows to the side of the cover 432 that is away from the panel 10 and the stop edge 61, and the outer periphery of the cap ring 431. Optionally, in Figures 12-18 , Figures 19-22In the cooking stove shown, the baffle 43 is fixed to the end of the support 42 that is relatively far from the assembly end 421 and the sensing element 41, and supports the pot rack 70, as shown. Figure 17 As shown, the baffle 43 and the support 42 are integrally formed. The weighing component 40 also includes a weighing pan 44 on the side of the panel 10 facing away from the top. The weighing pan 44 is a horizontally extended plate and is housed in the stove cavity 24 by the panel 10 and the stove plate 20. It is connected to the sensing component 41 by the second fastener. The assembly end 421 is connected to the weighing pan 44 by the first fastener 81.

[0060] Specifically, the first fastener 81 can be a first threaded component 811. The first threaded component 811, the stop cap 43, and the support component 42 are coaxially arranged. The first threaded component 811 can be a bolt. The nut head of the first threaded component 811 is located on the side of the weighing pan 44 facing away from the panel 10. The thread of the first threaded component 811 passes through the weighing pan 44 and protrudes from the side of the weighing pan 44 closest to the panel 10. Figures 12-18 , Figures 19-22 The connection process between the support member 42 and the weighing pan 44 is as follows: First, the support member 42 is passed through the surrounding hole 62 of the liquid tray 60 and the through hole 11 of the panel 10 in sequence so that the assembly end 421 extends into the stove cavity 24. Then, the assembly end 421 forms a threaded engagement with the screw of the first threaded component 811. Next, the stop cap 43 is held and the support member 42 is rotated, so that the thread engagement size between the assembly end 421 and the first threaded component 811 gradually increases until the nut heads of the assembly end 421 and the first threaded component 811 respectively abut against the two sides of the weighing pan 44, tightening and fixing the weighing pan 44. Finally, the sensing element 41 and the support member 42 are both connected to the weighing pan 44. With this configuration, the process of connecting the support member 42 and the weighing pan 44 is simple and easy to complete by hand.

[0061] See Figure 2 , Figures 4-6In another embodiment of this utility model, the support member 42 and the baffle cap 43 are separately formed. The baffle cap 43 further includes a hollow sleeve portion 434 and an abutment portion 435 protruding from the inner wall of the sleeve portion 434. The sleeve portion 434 is coaxially sleeved on the end of the support member 42 that is relatively far from the assembly end 421 and the weighing pan 44. The abutment portion 435 abuts against the end face of the end of the support member 42 that is relatively far from the assembly end 421 and the weighing pan 44. The end of the sleeve portion 434 that is relatively far from the assembly end 421 and the weighing pan 44 supports the pot rack 70. The baffle cap 432 protrudes from the outer peripheral wall of the sleeve portion 434 and extends along the sleeve portion. The cover 434 and support 42 extend radially outward. One end of the cap ring 431 is bent and connected to the outer periphery of the cover 432. The other end of the cap ring 431 forms a pressure-resistant gap with the upper side of the panel 10. The cover 432, cap ring 431, and the outer periphery of the sleeve portion 434 together form a cap cavity 433 with an opening facing the panel 10. The end of the stop edge 61 that is relatively away from the panel 10 extends into the cap cavity 433. A third anti-contact gap is formed between the outer periphery of the stop edge 61 and the inner periphery of the cap ring 431. The stop edge 61 can either surround the sleeve portion 434 or not surround the sleeve portion 434. Figure 6 As shown, when the stop edge 61 surrounds the sleeve portion 434, a fifth anti-collision gap is formed between the inner circumference of the stop edge 61 and the outer circumference of the sleeve portion 434. An anti-collision gap is formed between the end of the stop edge 61 extending into the cap cavity 433 and the side of the cover 432 facing the panel 10. With this configuration, when the support member 42 is subjected to the load of food and the cooking pot, regardless of slight radial or axial movement of the support member 42, the cover 43 will not contact the panel 10 or the stop edge 61. Therefore, neither the panel 10 nor the stop edge 61 will share the weight of the food and the cooking pot, thus ensuring the accurate weighing results of the food and the cooking pot.

[0062] Further, see Figures 5-6The sleeve portion 434 has a tool hole 437 at the end opposite to the weighing pan 44 and the assembly end 421. The abutment portion 435 has a fastening hole 436 communicating with the tool hole 437. The cap 43 also includes a third fastener and a plug 438. The third fastener passes through the fastening hole 436 to fix the abutment portion 435 and the support member 42 at the end opposite to the assembly end 421. The third fastener can be a threaded connector. The tool hole 437 allows an external tool to be inserted into the sleeve portion 434 to facilitate the external tool connecting the third fastener and applying the force required to fix the abutment portion 435 and the support member 42 to the third fastener. 2. After the connection is fixed, the third fastener is located inside the sleeve portion 434. The plug 438 is inserted from the end of the sleeve portion 434 that is relatively far away from the weighing pan 44 and the assembly end 421, and is press-fitted with the inner wall of the sleeve portion 434. Finally, the plug 438 seals the opening of the end of the sleeve portion 434 that is relatively far away from the weighing pan 44. With this setting, the plug 438 can prevent residual water droplets, soup and other liquids on the food from leaking into the sleeve portion 434. This can protect the third fastener from rust and damage, and also ensure that no oil adheres between the sleeve portion 434 and the support member 42 to maintain sufficient static friction and prevent the cap 43 from rotating or loosening relative to the support member 42.

[0063] See Figure 1 , Figure 8 , Figures 10-11 , Figure 12 as well as Figure 19 In some embodiments, the number of support members 42 and the number of baffles 43 are both multiple and equal. The multiple support members 42 and the multiple baffles 43 are connected one-to-one. The bottom of the pot rack 70 is provided with an annular limiting groove 71. The multiple support members 42 are arranged in a ring around the axis of the annular limiting groove 71 as the center. The axis of the annular limiting groove 71 is perpendicular to the panel 10 and extends in the vertical direction. The multiple baffles 43 extend into the annular limiting groove 71 and abut against the bottom wall of the annular limiting groove 71. The bottom wall of the annular limiting groove 71 faces the upper side of the panel 10, and the multiple baffles 43 are limited and abutted by the side wall of the annular limiting groove 71, thereby restricting the freedom of the pot rack 70 to slide radially and fall onto the panel 10. With this configuration, the pot rack 70 can rotate around its own axis at any angle and be placed on multiple baffles 43. When placing the pot rack 70 on the baffles 43, there is no need to deliberately find the exact angle of the pot rack 70, which improves the ease of placement of the pot rack 70.

[0064] It is understood that in some embodiments not shown in the figure, the stop cap 43 may not need to be located at the end of the support member 42 that is relatively far from the assembly end 421 and the weighing pan 44, and the stop cap 43 may not need to support the bottom of the pot rack 70 or the cooking pot, as long as the stop cap 43 can surround the outer periphery of the stop edge 61 by the cap ring 431.

[0065] In some embodiments, at least some of the heat dissipation holes 23 are formed in the cooktop 20, and the sensing element 41 is fixedly connected to the cooktop 20. (See reference...) Figure 1 , Figures 4-5 , Figures 8-9 , Figure 12 , Figures 14-15 as well as Figure 18 The stove body also includes a sub-plate 30 disposed in the stove cavity 24 and fixedly connected to the stove plate 20. The stove plate 20 includes a first bottom cover 21 and a first side plate 22. The first bottom cover 21 is disposed opposite to the lower side of the panel 10 at a distance. The first side plate 22 is bent and connected to the edge of the first bottom cover 21 and extends to the lower side of the panel 10. The lower side of the panel 10, the first bottom cover 21 and the first side plate 22 together form the stove cavity 24. The first bottom cover 21 includes a hollow portion 211 with heat dissipation holes 23. The sub-panel 30 includes a second bottom cover 31 and a second side plate 32. The second bottom cover 31 is located between the first bottom cover 21 and the panel 10. The second side plate 32 is bent and connected to the edge of the second bottom cover 31 and extends towards the first bottom cover 21. The hollow portion 211, the second bottom cover 31 and the second side plate 32 together form a cavity. This cavity serves as a heat insulation cavity 241 and is part of the stove cavity 24. The sensing element 41 and the weighing pan 44 are both located in the heat insulation cavity 241. In this case, the stove cavity 24 also includes a furnace cavity 242. The furnace cavity 242 is formed on the other side of the sub-panel 30 opposite to the heat insulation cavity 241. The heating element 51 is placed in the furnace cavity 242. With this configuration, the heat from the heating element 51 is stored in the furnace cavity 242. The auxiliary plate 30 can block some of the heat so that it does not enter the heat insulation cavity 241, thereby reducing the temperature inside the heat insulation cavity 241 to protect the sensing element 41. In addition, the perforated portion 211 connects the heat insulation cavity 241 to the outside of the stove body, allowing gas exchange between the heat insulation cavity 241 and the outside of the stove body. This facilitates the gas carrying heat out of the heat insulation cavity 241 to further reduce the temperature inside the heat insulation cavity 241.

[0066] See Figures 3-4 , Figure 8 , Figures 13-14 , Figure 18The second bottom cover 31 of the auxiliary plate 30 is a horizontally extending plate structure. The second bottom cover 31 and the hollowed-out portion 211 of the cooktop 20 are spaced apart and parallel. The second bottom cover 31 has a mounting through hole 312 for the support member 42 to pass through. The support member 42 passes through the mounting through hole 312 through the auxiliary plate 30 so that the assembly end 421 protrudes from the side of the second bottom cover 31 facing away from the panel 10 and extends into the heat insulation cavity 241. The assembly end 421 and the weighing pan 44 located in the heat insulation cavity 241 are fixedly connected by the first fastener 81. A fourth anti-contact gap is formed between the outer periphery of the support member 42 and the hole wall of the mounting through hole 312. The fourth anti-contact gap provides radial movement space for the support member 42, allowing the support member 42 to move slightly relative to the auxiliary plate 30 after being subjected to force, so as to prevent the support member 42 and the auxiliary plate 30 from contacting each other and ensuring that the auxiliary plate 30 does not share the weight of the food and cooking pot, so as to achieve accurate weighing of the food and cooking pot. Figures 1 to 18 In the cooking stove shown, the panel 10, the second bottom cover 31, the sensing element 41, the weighing pan 44, and the hollow part 211 are arranged vertically in sequence and gradually approach the ground. A floating gap is formed between the weighing pan 44 and the hollow part 211. When the cooking pot is placed on the pot rack 70 or directly supported by the support member 42, the support member 42 is compressed and moves slightly closer to the ground, thereby causing the weighing pan 44 to move slightly away from the second bottom cover 31 and closer to the hollow part 211. The floating gap can ensure that the weighing pan 44 will not contact the hollow part 211. The sensing element 41 includes a tension sensor 412 with its two ends connected to the second bottom cover 31 and the weighing pan 44 respectively. The tension sensor 412 is stretched as the weighing pan 44 approaches the hollow part 211 and its internal tensile strain increases. The tension sensor 412 can also be replaced by a tensile strain sensor.

[0067] Figures 1 to 18 In the cooking stove shown, the second side plate 32 of the auxiliary plate 30 and the first bottom cover 21 of the cooktop 20 are fixedly connected by fasteners. When the support member 42 slightly decreases under the pressure of the cooking pot and food, the tension on the sensing element 41 increases, and the sensing element 41 applies a pulling force to the second bottom cover 31 in a direction close to the ground. The second side plate 32 applies a pressure to the first bottom cover 21 in a direction close to the ground. Compared to the sensing element 41 being directly connected to the first bottom cover 21, the area of ​​action when the second side plate 32 applies pressure to the first bottom cover 21 is larger, thus reducing the pressure on the first bottom cover 21 and mitigating the deformation of the cooktop 20. By using the second bottom cover 31 of the auxiliary plate 30 instead of the first bottom cover 21 of the cooktop 20 to bear the force from the sensing element 41, the cooktop 20 can be designed to be lightweight and thinner, significantly reducing the weight of the cooking stove for easier installation. Furthermore, see [reference needed]. Figure 1 , Figures 4-5 as well as Figure 9The weighing pan 44 and the assembly end 421 of the support member 42 are fixedly connected by the first fastener 81. The weighing pan 44 and the sensing element 41 are connected by the second fastener. The heat dissipation hole 23 includes a first clearance hole 231 and a second clearance hole 232 opened in the hollow part 211. The opening of the first clearance hole 231 faces the first fastener 81 at intervals, and the opening of the second clearance hole 232 faces the second fastener at intervals. When the support member 42 is slightly close to the ground under the pressure of the food and cooking pot, the height of the floating gap decreases. At this time, at least a part of the first fastener 81 and at least a part of the second fastener enter the first clearance hole 231 and the second clearance hole 232 respectively, ensuring that the first fastener 81 and the second fastener will not contact or interfere with the stove plate 20. With this setting, the stove plate 20 will not share the weight of the food and cooking pot, and the weighing result of the weighing member 40 is accurate.

[0068] Optionally, for Figures 1 to 18 The cooking stove shown can also have the following structure for the cooktop 20: Figure 23 As shown, the orthographic projection of the first clearance hole 231 onto the horizontal plane can completely enclose the orthographic projection of the weighing pan 44 onto the same horizontal plane. The second side plate 32 of the sub-panel 30 is connected to the opening edge of the first clearance hole 231. This arrangement... Figure 23 The cooktop shown can avoid the entire weighing pan 44 through the first clearance hole 231. That is, when the weighing pan 44 moves away from the panel 10 and the second bottom cover 31 under the pressure of the support member 42, the weighing pan 44 can be inserted into the first clearance hole 231 without contacting the cooktop 20. Therefore, the situation where the cooktop 20 shares the weight of the food and the cooking pot is eliminated, and the weighing result is more accurate.

[0069] The first clearance hole 231 and the second clearance hole 232 allow air from outside the cooktop to enter the insulation cavity 241 to cool the sensing element 41. Optionally, the second side plate 32 is approximately perpendicular to the second bottom cover 31, and the shape of the weighing pan 44 is similar to that of the second bottom cover 31, with the size of the weighing pan 44 being slightly smaller than that of the second bottom cover 31. When the weighing is finished and the user removes the cooking pot from the pot rack 70, the sensing element 41 resets and deforms, causing the weighing pan 44 and the support member 42 to reset. The weighing pan 44 rises with the support member 42 away from the hollow portion 211. At this time, the height of the floating gap between the weighing pan 44 and the hollow portion 211 increases, and the air pressure in the floating gap decreases and becomes lower than the air pressure outside the cooktop. Therefore, the air located at the bottom of the first bottom cover 21 can be drawn into the floating gap through the first clearance hole 231 and the second clearance hole 232. The air entering the floating gap can cool the weighing pan 44 and the sensing element 41, and fills the insulation cavity 241 as the support member 42 and the weighing pan 44 reset. Preferably, for Figures 1-9 , Figures 12-18The cooking stove shown has a weighing pan 44 made of a material with a high thermal conductivity, and a secondary pan 30 made of a material with a lower thermal conductivity. A heat insulation layer can be installed on the secondary pan 30.

[0070] Furthermore, in some embodiments, the heating element 51 located within the furnace cavity 242 is fixedly connected to at least one of the cooktop 20 and the sub-plate 30, as long as the heating element 51 is located on the side of the sub-plate 30 facing away from the heat insulation cavity 241. A mounting space is formed between the lower side of the panel 10 and the second bottom cover 31 of the sub-plate 30, and the mounting space is used to mount at least a portion of the heating element 51. See also Figure 1 The panel 10 also has a burner opening 12 that runs through the upper and lower sides. The cooking stove also includes a stove platform 52 that connects to the heating element 51. Part of the stove platform 52 is located in the mounting space, and another part passes through the burner opening 12 and protrudes from the upper side of the panel 10. The stove platform 52 is used to ignite and heat the bottom of the cooking pot. Of course, the stove platform 52 can also heat the cooking pot in other ways. Multiple through holes 11 are configured, and the number of through holes 11 is equivalent to the number of support members 42. The axis of the stove platform 52 coincides with the axis of the pot rack 70, and the axis of the pot rack 70 coincides with the axis of the annular limiting groove 71. The multiple through holes 11 are arranged in a ring around the axis of the stove platform 52 as the center. See reference Figure 12 and Figure 19 In other embodiments, the panel 10 has a through hole 11 that extends through the upper and lower sides, allowing both the support member 42 to pass through and protrude from the upper side of the panel 10, and the stove 52 to pass through and protrude from the upper side of the panel 10.

[0071] In some embodiments, the heat dissipation hole 23 includes at least a first ventilation hole 233 formed in the hollow portion 211 of the cooktop 20. The auxiliary plate 30 is fixedly installed on the cooktop 20 and includes a second bottom cover 31 stacked on the side of the hollow portion 211 that is relatively close to the panel 10. Optionally, the heat dissipation hole 23 also includes a second ventilation hole 311 formed in the second bottom cover 31. The first ventilation hole 233 is connected to the second ventilation hole 311. The weighing pan 44 is located on the side of the second bottom cover 31 that is relatively close to the panel 10. The gap between the second bottom cover 31 and the weighing pan 44 is connected to the first ventilation hole 233, thereby connecting to the outside of the cooktop. The sensing element 41 includes a pressure sensor 411 and the opposite ends of the pressure sensor 411 are respectively connected to the second bottom cover 31 and the weighing pan 44. The pot rack 70, panel 10, weighing pan 44, sensing element 41, second bottom cover 31, and hollow portion 211 are arranged in sequence and gradually approach the ground. The pressure sensor 411 can also be replaced by a pressure strain sensor. The sensing element 41 supports the weighing pan 44. When the cooking pot is placed on the pot rack 70, the pot rack 70 applies pressure to the support member 42, the support member 42 applies pressure to the weighing pan 44, the weighing pan 44 applies pressure to the sensing element 41, the sensing element 41 applies pressure to the sub-pan 30, and the sub-pan 30 applies pressure to the stove plate 20. Under the pressure, the sensing element 41 undergoes slight compression deformation, and the height of the gap between the weighing pan 44 and the second bottom cover 31 decreases. After the user removes the cooking pot from the pot rack 70, the pressure on the sensing element 41 decreases, and the deformation is restored. The support member 42 and the weighing pan 44 move away from the first bottom cover 21 and move upward to reset. The air pressure between the weighing pan 44 and the second bottom cover 31 decreases and is less than the air pressure outside the stove body. Therefore, the air located at the bottom of the first bottom cover 21 can be drawn into the gap between the weighing pan 44 and the second bottom cover 31 through the first ventilation hole 233 and the second ventilation hole 311 and cool the sensing element 41. Optionally, the first ventilation hole 233 and the second ventilation hole 311 have the same shape and size, forming an airflow channel. The outlines of the first ventilation hole 233 and the second ventilation hole 311 are projected onto the same horizontal plane and overlap. With this arrangement, air passes through the airflow channel more smoothly and loses less kinetic energy, resulting in better cooling of the sensing element 41.

[0072] Further, see Figure 22 A space is formed between the lower side of the panel 10 and the weighing pan 44. The stove 52 and part of the heating element 51 are located in this space. In order to avoid the stove 52 and the heating element 51 exerting pressure on the weighing pan 44 and causing the weighing result of the weighing element 40 to be distorted, the cooking stove also includes a bracket 53. One end of the bracket 53 is fixedly connected to at least one of the auxiliary plate 30 and the stove plate 20, and the other end of the bracket 53 is fixedly connected to the stove 52 and the heating element 51. With this arrangement, the bracket 53 bears the weight of the heating element 51 and the stove 52 and keeps the stove 52 and the heating element 51 fixed relative to the auxiliary plate 30 and the stove plate 20, preventing the weighing pan 44 from being interfered with due to accidental movement of the stove 52 and the heating element 51.

[0073] Optionally, in Figures 19-22 Based on the cooking stove shown, the heat dissipation hole 23 also includes a first clearance hole 231 opened in the auxiliary plate 30. The weighing pan 44 and the support member 42 are connected by a first fastener 81. The first fastener 81 can be a bolt or other form of first threaded member 811. The nut head of the bolt abuts against the side of the weighing pan 44 that is away from the assembly end 421 and the panel 10. The bolt thread passes through the weighing pan 44 and extends into the assembly end 421. The two sides of the weighing pan 44 are clamped by the nut head and the assembly end 421 respectively. The openings of the first clearance hole 231 face the first fastener 81 at intervals. With this arrangement, when the support member 42 is pressed and moves down slightly, the first fastener 81 can be driven by the support member 42 into the first clearance hole 231. For example, the nut head of the first threaded member 81 enters the clearance hole, thereby preventing the first fastener 81 from contacting the auxiliary plate 30, ensuring that the auxiliary plate 30 does not share the weight of the food and cooking pot, and ensuring accurate weighing results.

[0074] Figures 19-22 In the cooking stove shown, the first bottom cover 21, the second bottom cover 31, the sensing element 41, the weighing pan 44, and the panel 10 are arranged in sequence along the direction away from the ground. Compared with the sensing element 41 being directly connected to the first bottom cover 21 and applying pressure to the first bottom cover 21, the sensing element 41 being directly connected to the second bottom cover 31 and applying pressure to the first bottom cover 21 through the second bottom cover 31 can reduce the pressure on the first bottom cover 21, thereby reducing the deformation amplitude of the first bottom cover 21 when it is under pressure. The force-bearing area of ​​the first bottom cover 21 under the pressure of the second bottom cover 31 is significantly larger than the force-bearing area of ​​the first bottom cover 21 under the pressure of the sensing element 41.
