Description

Technical Field

[0001] This utility model relates to the field of stove technology, specifically to a stove. Background Technology

[0002] As the usage rate of gas stoves increases, people's requirements for stove safety are also rising. Gas stoves are usually equipped with thermocouples, which can detect whether the flame of the gas stove is burning normally and ensure that the gas supply is automatically cut off when the flame goes out, thereby preventing gas leaks and accidents.

[0003] In addition, most gas stoves on the market currently use an external temperature sensor that contacts the bottom of the pot to detect its temperature. When the pot's bottom temperature exceeds a preset temperature, the stove automatically shuts off to protect the flame. Simultaneously, if the stove accidentally goes out or a pot is left unattended on high heat for an extended period, the gas supply can be cut off immediately based on the external temperature sensor's readings to prevent accidents. However, external temperature sensors have certain limitations in use. For example, because they need to contact the bottom of the pot, only flat-bottomed pans can be used for cooking to avoid interference. Furthermore, external temperature sensors are susceptible to flame interference, which can cause them to inaccurately detect the pot's bottom temperature, leading to abnormal flameouts.

[0004] If the temperature sensor is placed in the bottom shell, it can avoid contact with the bottom of the pot. However, since the thermocouple generates heat when it is working, a large amount of heat can easily accumulate in the bottom shell, affecting the detection accuracy and service life of the temperature sensor. Utility Model Content

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a stove is provided, the technical solution of which is as follows.

[0006] The cooktop includes a bottom shell, a control panel, burners, a thermocouple, and a temperature sensor. The bottom shell encloses an open mounting cavity. The control panel is mounted on the bottom shell and covers the opening. A portion of the burners is located within the mounting cavity. The thermocouple and temperature sensor are connected to the burners, with the temperature sensor situated within the mounting cavity. The bottom shell has a bottom wall and side walls. The bottom wall is positioned opposite the control panel, and the side walls are located between the bottom wall and the control panel. The bottom wall has a first region and a second region. The projection of the temperature sensor onto the plane of the bottom wall lies within the first region. The second region is closer to the side wall than the first region and has ventilation holes for heat dissipation from the thermocouple.

[0007] This invention relates to a cooktop that uses a temperature sensor to detect the temperature of the burner head and thus the temperature of the pot bottom. The temperature sensor is located within the mounting cavity and is unaffected by the flame. Even when using a pointed-bottom pot, the temperature sensor will not interfere with the pot, expanding the cooktop's applicability. Furthermore, heat dissipation holes are formed on the bottom wall of the bottom shell cavity. These holes are positioned closer to the thermocouple than the temperature sensor, ensuring that the heat generated by the thermocouple can be dissipated as much as possible. This prevents damage to the temperature sensor, effectively improving its detection accuracy and lifespan, and enhancing the safety and reliability of the cooktop.

[0008] For example, the burner head includes an ejector tube and a support. Both the ejector tube and the thermocouple are mounted on the support and positioned by the support. Thus, by mounting the ejector tube and thermocouple on the support, the overall structural design of the burner head can be optimized, making it more compact and stable. Furthermore, the positioning of the ejector tube and thermocouple by the support not only reduces distance errors between them during installation, effectively improving the stability of the burner head, but also simplifies the assembly process, reducing assembly steps and time, and facilitating subsequent maintenance and replacement, significantly reducing maintenance costs.

[0009] For example, the temperature sensor is mounted on the support. By sensing the temperature of the support through the temperature sensor, the temperature of the pot bottom can be detected (i.e., the temperature of the pot can be detected indirectly). This not only ensures that the temperature sensor can sense the temperature of the pot bottom in real time, but also avoids interference or damage to the temperature sensor caused by the close distance between the temperature sensor and the flame. This effectively improves the accuracy of the temperature sensing results, thereby enhancing the safety and reliability of the stove.

[0010] For example, at least a portion of the temperature sensing element forms surface contact with the bracket. Along the length of the bottom shell, there is a first distance L1 between the surface contact location and the heat dissipation hole, where L1 is 30mm to 120mm. This first distance range between the surface contact location and the heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the heat dissipation hole, but also prevents the rapid loss of heat transferred to the bracket through the heat dissipation hole, thus avoiding inaccurate sensing results from the temperature sensing element. This effectively improves the reliability and accuracy of the temperature sensing element.

[0011] For example, the temperature sensing element is mounted on the ejector tube. In this way, the temperature of the pot bottom can be detected by sensing the temperature of the ejector tube through the temperature sensing element (i.e., indirect detection of the pot temperature). This not only ensures that the temperature sensing element can sense the temperature of the pot bottom in real time, but also avoids interference or damage to the temperature sensing element due to the close distance between the temperature sensing element and the flame. This effectively improves the accuracy of the temperature sensing element, thereby enhancing the safety and reliability of the stove.

[0012] For example, at least a portion of the temperature sensing element forms surface contact with the ejector tube. Along the length of the bottom shell, there is a second distance L2 between the surface contact location and the heat dissipation hole, the second distance L2 being 15mm to 105mm. This second distance range between the surface contact location and the heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the heat dissipation hole, but also prevents the rapid loss of heat transferred to the ejector tube through the heat dissipation hole, thus avoiding inaccurate sensing results from the temperature sensing element. This effectively improves the reliability and accuracy of the temperature sensing element.

[0013] For example, the ejector tube is connected to a heat transfer element, and the temperature sensing element is disposed on the heat transfer element. Thus, the temperature sensing element can contact the heat transfer element. When the stove is in combustion mode, since the temperature of the heat transfer element is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the heat transfer element (i.e., indirectly detecting the pot temperature). The temperature sensing element is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that even when using a pointed-bottom pot, the temperature sensing element will not interfere with the pot, expanding the stove's applicability and effectively improving its practicality.

[0014] For example, at least a portion of the temperature sensing element forms surface contact with the heat transfer element. Along the length of the bottom shell, there is a third distance L3 between the surface contact location and the heat dissipation hole, where L3 is 15mm to 105mm. This third distance range between the surface contact location and the heat dissipation hole not only ensures that the heat generated by the temperature sensing element during operation can be dissipated through the heat dissipation hole, but also prevents the rapid loss of heat transferred to the heat transfer element through the heat dissipation hole, thus avoiding inaccurate temperature sensing results. This effectively improves the reliability and accuracy of the temperature sensing element.

[0015] For example, the projection of the bracket onto the plane of the cavity bottom wall is located within the first region. In this way, a certain distance can be maintained between the bracket and the heat dissipation hole, so that when the heat from the bottom of the pot is transferred to the bracket, the distance between the bracket and the heat dissipation hole is not too close, which would cause the heat to dissipate too quickly and thus lead to inaccurate temperature sensing results. This greatly improves the accuracy and stability of the temperature sensing results.

[0016] For example, the temperature sensor has a sensing surface, and in a direction perpendicular to the panel, there is a fourth distance Z between the sensing surface and the second area, the fourth distance Z being 40mm to 68mm. This fourth distance range between the sensing surface and the second area not only ensures that the heat generated by the temperature sensor during operation can be dissipated through the heat dissipation holes, but also prevents the heat from the stove head from rapidly dissipating through the heat dissipation holes, thus avoiding inaccurate sensing results from the temperature sensor, effectively improving the reliability and accuracy of the temperature sensor.

[0017] For example, there are multiple heat dissipation holes, which are spaced apart along the width of the bottom shell. This increases the contact area between heat and the external environment, allowing heat to be dissipated more evenly, effectively improving the heat dissipation efficiency of the cooktop and increasing its stability and lifespan.

[0034] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0035] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0036] One embodiment of this utility model provides a cooktop 10 that can protect the thermocouple 140 from heat and damage, effectively improving the sensitivity and service life of the thermocouple 140, thereby enhancing the safety and reliability of the cooktop 10. The cooktop 10 according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings.

[0037] See also Figure 1 , Figure 2 and Figure 3 The cooktop 10 includes a bottom shell 110, a panel 120, a burner head 130, a thermocouple 140, and a temperature sensor 150. The bottom shell 110 encloses a mounting cavity 1110 with an opening. The panel 120 is disposed on the bottom shell 110 and covers the opening. A portion of the burner head 130 is disposed within the mounting cavity 1110. The thermocouple 140 and the temperature sensor 150 are respectively connected to the burner head 130, and the temperature sensor 150 is located within the mounting cavity 1110. The bottom shell 110 has a cavity bottom wall 1111 and a cavity side wall 1112. The cavity bottom wall 1111 is disposed opposite to the panel 120. The cavity side wall 1112 is located between the cavity bottom wall 1111 and the panel 120. The cavity bottom wall 1111 has a first region 1111a and a second region 1111b. The projection of the temperature sensing element 150 onto the plane of the cavity bottom wall 1111 is located in the first region 1111a. The second region 1111b is closer to the cavity side wall 1112 than the first region 1111a. The second region 1111b is provided with heat dissipation holes 1111c for heat dissipation of the thermocouple 140.

[0038] Specifically, the cavity bottom wall 1111 and cavity side wall 1112 of the bottom shell 110 can be detachably connected or integrally formed. The detachable connection can include plug-in connection or adhesive connection, etc., and this application does not make specific limitations in this regard.

[0039] Specifically, the panel 120 can be a glass panel or a metal panel. The panel 120 can be covered on the bottom shell 110 to form a mounting cavity 1110. The burner head 130 can be set in the mounting cavity 1110, and some of the burner head 130 can extend out of the mounting cavity 1110 through the through hole to heat cookware and other items.

[0040] See Figure 2Thermocouple 140 can be connected to burner head 130 and located next to burner head 130. Thermocouple 140 can detect and monitor the combustion status of burner head 130 so as to quickly cut off the gas supply when burner head 130 is accidentally extinguished, and prevent safety accidents caused by gas leakage.

[0041] See Figure 4 The temperature sensing element 150 may include a heat-conducting part 1510, a sensing part 1520 and a signal transmission line 1530. The two ends of the sensing part 1520 may be connected to the heat-conducting part 1510 and the signal transmission line 1530 respectively. The heat-conducting part 1510 can transfer the heat generated by the burner head 130 to the sensing part 1520. The sensing part 1520 can convert the heat into temperature information and transmit it outward via the signal transmission line 1530.

[0042] Furthermore, the heat-conducting part 1510 can be made of a material with good thermal conductivity, such as copper or aluminum. This application does not specifically limit the material of the heat-conducting part 1510; any material with good thermal conductivity is acceptable. Moreover, the shape of the heat-conducting part 1510 can be determined according to different application scenarios and requirements. For example, the shape of the heat-conducting part 1510 can be circular, square, or irregular, etc. This application does not specifically limit the shape of the heat-conducting part 1510.

[0043] See Figure 2 and Figure 3 The bottom wall 1111 of the cavity can have adjacent first regions 1111a and second regions 1111b. Through the heat dissipation holes 1111c provided on the second region 1111b, the heat generated by the thermocouple 140 can be discharged from the mounting cavity 1110 in a timely manner. Furthermore, the second region 1111b can be closer to the cavity sidewall 1112 than the first region 1111a, so that the hot air flow in the mounting cavity 1110 can flow from the middle region of the bottom shell 110 to the edge region of the bottom shell 110. This can make the heat evenly distributed and reduce the overheating phenomenon that may occur in the middle region of the bottom shell 110 due to heat concentration.

[0044] Specifically, the heat dissipation hole 1111c can communicate with the mounting cavity 1110, so that the mounting cavity 1110 can communicate with the external environment. The shape and heat dissipation area of ​​the heat dissipation hole 1111c can be determined according to actual use needs, and this application does not impose specific limitations on it. For example, the shape of the heat dissipation hole 1111c can be elongated or circular, etc.

[0045] The stove 10 of this invention can detect the temperature of the burner head 130 by sensing the temperature of the burner head 130 through the temperature sensing element 150. The temperature sensing element 150 is located inside the mounting cavity 1110 and is not affected by the flame. Even when using a pointed-bottom pot, the temperature sensing element 150 will not interfere with the pot, thus expanding the applicability of the stove 10. Furthermore, heat dissipation holes 1111c are formed on the bottom wall 1111 of the bottom shell 110. The heat dissipation holes 1111c are located closer to the thermocouple 140 than the temperature sensing element 150, thereby ensuring that the heat generated by the thermocouple 140 can be dissipated through the heat dissipation holes 1111c as much as possible, avoiding any impact or damage to the temperature sensing element 150. This effectively improves the detection accuracy and service life of the temperature sensing element 150, and enhances the safety and reliability of the stove 10.

[0046] In some embodiments, see Figure 5 The burner head 130 includes an ejector tube 1310 and a bracket 1320. Both the ejector tube 1310 and the thermocouple 140 are mounted on the bracket 1320 and positioned by the bracket 1320. By mounting the ejector tube 1310 and the thermocouple 140 on the bracket 1320, the overall structural design of the burner head 130 can be optimized, making it more compact and stable. Furthermore, the positioning of the ejector tube 1310 and the thermocouple 140 by the bracket 1320 not only reduces the distance error between the ejector tube 1310 and the thermocouple 140 during installation, effectively improving the stability of the burner head 130, but also simplifies the assembly process, reducing assembly steps and time, and facilitating subsequent maintenance and replacement, thus greatly reducing maintenance costs.

[0047] Specifically, the number and type of ejector tubes 1310 can be determined according to the type of burner head 130. Figure 3 For example, Figure 3 The burner head 130 shown is a double-ring burner head 130. When the burner head 130 is a double-ring burner head, the injector tube 1310 may include an inner ring injector tube 1311 and an outer ring injector tube 1312. When the burner head 130 is a triple-ring burner head, the injector tube 1310 may include an inner ring injector tube 1311, a middle ring injector tube, and an outer ring injector tube 1312. One end of the injector tube 1310 can be connected to a gas source, and the other end of the injector tube 1310 can be threaded onto the bracket 1320.

[0048] See Figure 6 The bracket 1320 may have a plate 1321 and a foot 1322. One end of the foot 1322 may be mounted on the plate 1321. The end of the foot 1322 away from the plate 1321 may form a connecting end 1323, which can be fixedly connected to the bottom shell 110 of the stove 10 to fix the burner head 130.

[0049] The thermocouple 140 can be fixed to the bracket 1320 by a detachable connection. Specifically, the thermocouple 140 and the bracket 1320 can be connected by plug-in connection or threaded connection, etc. This application does not make specific limitations in this regard.

[0050] In some embodiments, see Figure 6 and Figure 7 The temperature sensing element 150 is mounted on the bracket 1320. By sensing the temperature of the bracket 1320 through the temperature sensing element 150, the temperature of the bottom of the pot can be detected (i.e., the temperature of the pot can be detected indirectly). This not only ensures that the temperature sensing element 150 can sense the temperature of the bottom of the pot in real time, but also avoids interference or damage to the temperature sensing element 150 due to the close distance between the temperature sensing element 150 and the flame of the burner 130. This effectively improves the accuracy of the temperature sensing result of the temperature sensing element 150, thereby improving the safety and reliability of the stove 10.

[0051] The temperature sensor 150 can be mounted on the bracket 1320 so that it can form surface contact with the bracket 1320. When the cookware is heated, the temperature of the bottom of the cookware above the burner 130 can be transferred to the bracket 1320, thus correlating the temperature of the bracket 1320 with the temperature of the bottom of the cookware. Therefore, the temperature sensor 150 can determine the temperature of the bottom of the cookware by sensing the temperature of the bracket 1320. Specifically, the bracket 1320 can be made of a material with good thermal conductivity, such as stainless steel.

[0052] See Figure 6 and Figure 7 The temperature sensor 150 can be detachably connected to the bracket 1320 via fasteners 170. The fasteners 170 can be bolts or screws, etc. This detachable connection allows the temperature sensor 150 to be quickly installed on the bracket 1320, effectively saving installation time and costs. Furthermore, when the temperature sensor 150 needs replacement or maintenance, it can be easily disassembled and assembled, greatly reducing the workload and costs required for disassembly and assembly.

[0053] In embodiments not shown, the temperature sensing element 150 may also be connected to the bracket 1320 by other means, such as welding, riveting, gluing, snap-fit ​​connection, etc.

[0054] In some embodiments, at least a portion of the temperature sensing element 150 forms surface contact with the bracket 1320. Along the length of the bottom housing 110, a first distance L1 exists between the surface contact location and the heat dissipation hole 1111c, where L1 is 30mm to 120mm. This first distance range between the surface contact location and the heat dissipation hole 1111c ensures that the heat generated by the temperature sensing element 150 during operation can be dissipated through the heat dissipation hole 1111c, and also prevents the rapid loss of heat transferred to the bracket 1320 through the heat dissipation hole 1111c, thus avoiding inaccurate sensing results from the temperature sensing element 150. This effectively improves the reliability and accuracy of the temperature sensing element 150.

[0055] Specifically, the value of the first distance L1 ranges from 30 mm to 120 mm, for example, 30 mm, 50 mm, 85 mm, 100 mm, 120 mm, etc., preferably 85 mm.

[0056] The distance between the contact point and the heat dissipation hole 1111c should not be too large or too small. If the first distance is too large, the heat generated by the temperature sensing element 150 during operation cannot be dissipated through the heat dissipation hole 1111c, causing the heat generated by the temperature sensing element 150 to accumulate in the mounting cavity 1110, which may damage the temperature sensing element 150 and thermocouple 140. If the first distance is too small, the heat on the bracket 1320 may be dissipated quickly through the heat dissipation hole 1111c, which may affect the sensing result of the temperature sensing element 150. Specifically, it may cause the value sensed by the temperature sensing element 150 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 150.

[0057] See again Figure 3 In the width direction of the bottom shell 110, there is a fifth distance L5 between the surface contact location and the heat dissipation hole 1111c. Specifically, the value of the fifth distance L5 ranges from 5 mm to 30 mm, for example, 5 mm, 10 mm, 15 mm, 20 mm, 30 mm, etc., preferably 15 mm.

[0058] In some embodiments, see Figure 8 The temperature sensing element 150 is mounted on the ejector tube 1310. By sensing the temperature of the ejector tube 1310 through the temperature sensing element 150, the temperature of the bottom of the pot can be detected (i.e., the temperature of the pot can be detected indirectly). This not only ensures that the temperature sensing element 150 can sense the temperature of the bottom of the pot in real time, but also avoids interference or damage to the temperature sensing element 150 due to the close distance between the temperature sensing element 150 and the flame of the burner 130. This effectively improves the accuracy of temperature sensing by the temperature sensing element 150, thereby improving the safety and reliability of the stove 10.

[0059] Specifically, the ejector tube 1310 may include an inner ring ejector tube 1311 and an outer ring ejector tube 1312, and the temperature sensing element 150 may be attached to one or more of the ejector tubes 1310, preferably attached to the inner ring ejector tube 1311.

[0060] When the cookware is heated, the temperature of the bottom of the pot above the burner head 130 can be transferred to the ejector tube 1310, thus relating the temperature of the ejector tube 1310 to the temperature of the bottom of the pot. Therefore, the temperature sensor 150 can determine the temperature of the burner head 130 by sensing the temperature of the ejector tube 1310. Specifically, the ejector tube 1310 can be made of a heat-conducting material, such as metal or other materials with good heat transfer properties, so that the temperature sensor 150 can sense the temperature of the ejector tube 1310.

[0061] In some embodiments, at least a portion of the temperature sensing element 150 forms surface contact with the ejector tube 1310. Along the length of the bottom housing 110, a second distance L2 exists between the surface contact location and the heat dissipation hole 1111c, where L2 is 15mm to 105mm. This second distance range between the surface contact location and the heat dissipation hole 1111c not only ensures that the heat generated by the temperature sensing element 150 during operation can be dissipated through the heat dissipation hole 1111c, but also prevents the rapid loss of heat transferred to the ejector tube 1310 through the heat dissipation hole 1111c, thus avoiding inaccurate sensing results from the temperature sensing element 150. This effectively improves the reliability and accuracy of the temperature sensing element 150.

[0062] Specifically, the value of the second distance L2 ranges from 15 mm to 105 mm, for example, 15 mm, 50 mm, 70 mm, 85 mm, 105 mm, etc., preferably 70 mm.

[0063] The distance between the contact point and the heat dissipation hole 1111c should not be too large or too small. If the first distance is too large, the heat generated by the temperature sensing element 150 during operation cannot be dissipated through the heat dissipation hole 1111c, causing the heat generated by the temperature sensing element 150 to accumulate in the mounting cavity 1110, which may damage the temperature sensing element 150 and thermocouple 140. If the first distance is too small, the heat on the ejector tube 1310 may be quickly dissipated through the heat dissipation hole 1111c, which may affect the sensing result of the temperature sensing element 150. Specifically, it may cause the value sensed by the temperature sensing element 150 to be too low, failing to accurately reflect the actual sensed value, thus affecting the accuracy of the sensing result of the temperature sensing element 150.

[0064] In some embodiments, see Figure 9 and Figure 10The ejector tube 1310 is connected to a heat transfer element 160, and a temperature sensing element 150 is disposed on the heat transfer element 160. Thus, the temperature sensing element 150 can contact the heat transfer element 160. When the stove 10 is in combustion mode, since the temperature of the heat transfer element 160 is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the heat transfer element 160 through the temperature sensing element 150 (i.e., indirectly detecting the pot temperature). The temperature sensing element 150 is not affected by the flame, ensuring not only the accuracy and speed of temperature detection, but also that even when using a pointed-bottom pot, the temperature sensing element 150 will not interfere with the pot, expanding the applicability of the stove 10 and effectively improving its practicality.

[0065] For a single-ring burner head, there is only one ejector tube 1310, and the heat transfer element 160 can be connected to this single ejector tube 1310. For a double-ring burner head, the ejector tube 1310 may include an inner ring ejector tube 1311 and an outer ring ejector tube 1312. In this case, the heat transfer element 160 can be connected to the inner ring ejector tube 1311, or the heat transfer element 160 can also be connected to the outer ring ejector tube 1312, or the heat transfer element 160 can be connected to both the inner ring ejector tube 1311 and the outer ring ejector tube 1312 simultaneously. For a triple-ring burner head, there are three ejector tubes 1310, typically including an inner ring ejector tube 1311, a middle ring ejector tube, and an outer ring ejector tube 1312. In this case, the heat transfer element 160 can be connected to at least one of the three: the inner ring ejector tube 1311, the middle ring ejector tube, or the outer ring ejector tube 1312. (See also...) Figure 9 and Figure 10 The heat transfer element 160 can be disposed on the inner ring ejector tube 1311. It should be understood that when a pot is placed on the burner head 130, the central area of ​​the pot bottom is typically where heat is concentrated. When there are two or more ejector tubes 1310, the inner ring ejector tube 1311 is closer to the center of the burner head 130, and its temperature better reflects the temperature of the pot bottom. Therefore, connecting the heat transfer element 160 to the inner ring ejector tube 1311 allows the heat transfer element 160 to more accurately reflect the temperature of the pot bottom. In embodiments not shown, the heat transfer element 160 can also be disposed on ejector tubes 1310 other than the inner ring ejector tube 1311.

[0066] Specifically, see Figure 10The heat transfer element 160 may have a sleeve portion 1610, and the ejector tube 1310 may have a mating section 1313. A through hole (not shown in the figure) may be provided on the sleeve portion 1610. The sleeve portion 1610 can be fitted onto the mating section 1313 through the through hole. To ensure connection stability, the sleeve portion 1610 can also be connected to the mating section 1313 by means of adhesive, welding, or snap-fit. This facilitates the installation of the heat transfer element 160, and because the temperature of the pot bottom above the burner head 130 is transferred to the sleeve portion 1610 through the ejector tube 1310 when the pot is heated, the temperature of the heat transfer element 160 is correlated with the temperature of the pot bottom, ensuring accurate and rapid temperature detection.

[0067] Further, see Figure 10 The outer edge of the sleeve portion 1610 can extend into a plate-shaped portion 1611. The plate-shaped portion 1611 can have a surface to be measured 1612. The temperature sensing element 150 can be attached to the surface to be measured 1612. This facilitates the installation of the temperature sensing element 150, and since the temperature of the pot bottom above the burner 130 is transferred to the plate-shaped portion 1611 through the injector tube 1310 when the pot is heated, the temperature of the plate-shaped portion 1611 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0068] It should be understood that in this embodiment of the invention, the temperature sensing element 150 indirectly detects the temperature of the pot bottom by detecting the temperature of the heat transfer element 160. To ensure the accuracy of temperature detection, the heat transfer element 160 can be made of a thermally conductive material, such as metal or other materials with good thermal conductivity. Specifically, the heat transfer element 160 and the ejector tube 1310 can be made of the same material, such as stainless steel, thus forming a stainless steel assembly.

[0069] In some embodiments, at least a portion of the temperature sensing element 150 forms surface contact with the heat transfer element 160. Along the length of the bottom shell 110, a third distance L3 exists between the surface contact location and the heat dissipation hole 1111c, where L3 is 15mm to 105mm. This third distance range between the surface contact location and the heat dissipation hole 1111c not only ensures that the heat generated by the temperature sensing element 150 during operation can be dissipated through the heat dissipation hole 1111c, but also prevents the heat transferred to the heat transfer element 160 from rapidly dissipating through the heat dissipation hole 1111c, thus avoiding inaccurate sensing results from the temperature sensing element 150. This effectively improves the reliability and accuracy of the temperature sensing element 150.

[0070] At least a portion of the temperature sensing element 150 forms surface contact with the heat transfer element 160 connected to the ejector tube 1310. When the stove 10 is in combustion mode, since the temperature of the heat transfer element 160 is related to the temperature of the bottom of the pot, the temperature of the bottom of the pot can be detected by sensing the temperature of the heat transfer element 160 through the temperature sensing element 150 (i.e., indirectly detecting the temperature of the pot). The temperature sensing element 150 is not affected by the flame, which not only ensures the accuracy and speed of temperature detection, but also ensures that the temperature sensing element 150 will not interfere with the pot even when using a pointed bottom pot, thus expanding the applicability of the stove 10. At the same time, the third distance L3 is within this range, which further ensures the accuracy and speed of temperature detection.

[0071] Specifically, the value of the third distance L3 ranges from 15 mm to 105 mm, for example, 15 mm, 50 mm, 70 mm, 85 mm, 105 mm, etc., preferably 70 mm.

[0072] The distance between the contact point and the heat dissipation hole 1111c should not be too large or too small. If the first distance is too large, the heat generated by the temperature sensing element 150 during operation cannot be dissipated through the heat dissipation hole 1111c, causing the heat generated by the temperature sensing element 150 to accumulate in the mounting cavity 1110, which may damage the temperature sensing element 150 and thermocouple 140. If the first distance is too small, the heat on the heat transfer element 160 may be quickly dissipated through the heat dissipation hole 1111c, thus affecting the sensing result of the temperature sensing element 150. Specifically, it may cause the value sensed by the temperature sensing element 150 to be too low, failing to accurately reflect the actual sensed value, thereby affecting the accuracy of the sensing result of the temperature sensing element 150.

[0073] In some embodiments, see Figure 2 and Figure 3 The projection of the bracket 1320 onto the plane of the cavity bottom wall 1111 is located within the first region 1111a. This allows for a certain distance between the bracket 1320 and the heat dissipation hole 1111c. When heat from the bottom of the pot is transferred to the bracket 1320, the distance between the bracket 1320 and the heat dissipation hole 1111c is prevented from being too close, which would lead to rapid heat loss and inaccurate sensing results from the temperature sensor 150. This significantly improves the accuracy and stability of the temperature sensor 150's sensing results.

[0074] In some embodiments, in conjunction with reference Figure 4 and Figure 11The temperature sensing element 150 has a sensing surface 1511. In a direction perpendicular to the panel 120, there is a fourth distance Z between the sensing surface 1511 and the second region 1111b, which is 40mm to 68mm. This fourth distance range between the sensing surface 1511 and the second region 1111b not only ensures that the heat generated by the temperature sensing element 150 during operation can be dissipated through the heat dissipation hole 1111c, but also prevents the heat from the burner head 130 from rapidly dissipating through the heat dissipation hole 1111c, thus avoiding inaccurate sensing results from the temperature sensing element 150. This effectively improves the reliability and accuracy of the temperature sensing element 150.

[0075] The sensing surface 1511 can be formed on the heat-conducting part 1510 of the temperature sensing element 150. The sensing surface 1511 can be connected to the burner head 130 to transfer the heat of the burner head 130 to the temperature sensing element 150.

[0076] Specifically, the fourth distance Z ranges from 40 mm to 68 mm, for example, 40 mm, 45 mm, 54 mm, 70 mm, 68 mm, etc., preferably 54 mm.

[0077] The distance between the sensing surface 1511 and the second region 1111b should not be too large or too small. When the fourth distance is too large, the heat generated by the temperature sensing element 150 during operation cannot be dissipated through the heat dissipation hole 1111c, causing the heat generated by the temperature sensing element 150 to accumulate in the mounting cavity 1110, which may damage the temperature sensing element 150 and thermocouple 140. When the first distance is too small, the heat from the furnace head 130 may be dissipated quickly through the heat dissipation hole 1111c, thus affecting the sensing result of the temperature sensing element 150. Specifically, it may cause the value sensed by the temperature sensing element 150 to be too low, failing to accurately reflect the actual sensed value, thereby affecting the accuracy of the sensing result of the temperature sensing element 150.

[0078] In some embodiments, see Figure 2 and Figure 3 Multiple heat dissipation holes 1111c are provided, spaced apart along the width of the bottom shell 110. This increases the contact area between heat and the external environment, allowing heat to be dissipated more evenly, effectively improving the heat dissipation efficiency of the cooktop 10 and increasing its stability and lifespan.

[0079] The spacing between the multiple heat dissipation holes 1111c in the width direction of the bottom shell 110 can be determined according to the actual situation or usage requirements, and this application does not make a specific limitation in this regard. For example, when it is necessary to ensure that the heat dissipation area of ​​the heat dissipation holes 1111c can cover the second region 1111b, the spacing between the multiple heat dissipation holes 1111c can be 10 mm.
