Description

Technical Field

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

[0002] As the usage rate of gas stoves increases, people's requirements for their safety are also rising. Gas stoves are typically equipped with a drip tray and an external temperature sensor. The drip tray is used to catch liquids that splash during cooking. It has a through-hole through which the external temperature sensor passes, allowing it to contact the bottom of the pot to detect its temperature. If the bottom temperature exceeds a preset temperature, the stove will automatically shut off to prevent accidents. Simultaneously, if the stove accidentally shuts off or if 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.

[0003] However, since the external temperature sensor needs to be in contact with the bottom of the pot, only a flat-bottomed pan can be used for cooking to avoid interference with the external temperature sensor. In addition, the external temperature sensor is easily affected by the flame, which may cause it to fail to accurately detect the temperature of the bottom of the pot, resulting in the stove malfunctioning and shutting off. Finally, since the external temperature sensor passes through the through hole in the liquid tray, the temperature of the liquid tray itself and the temperature of the liquid it holds may affect the detection results of the external temperature sensor. Utility Model Content

[0004] In order to at least partially solve the problems existing in the prior art, according to one aspect of the present invention, a burner head is provided, the technical solution of which is as follows.

[0005] The burner head includes a liquid tray, an ejector tube, a support, and a temperature sensing element. The support is located below the liquid tray. The ejector tube passes through the support and the liquid tray sequentially from bottom to top and is positioned by the support. The temperature sensing element is mounted on the support. The liquid tray has a protrusion at the position corresponding to the temperature sensing element. The protrusion protrudes away from the temperature sensing element and forms a cavity.

[0006] The burner head of this utility model, on the one hand, when used on a gas stove, because the temperature of the support is related to the temperature of the pot bottom, and the temperature sensing element is located on the support below the liquid tray, the temperature of the pot bottom can be detected by sensing the temperature of the support (i.e., indirectly detecting the pot temperature) through the temperature sensing element. This not only prevents the temperature sensing element from being affected by the flame, ensuring the accuracy of temperature detection, but also avoids interference between the temperature sensing element and the pot, thereby expanding the types of pots that can be used on the stove and broadening the applicability of the stove; on the other hand, the protrusion protrudes away from the temperature sensing element and... The cavity not only allows the liquid on the protrusion to flow to other parts of the liquid tray, reducing the influence of the liquid temperature on the temperature sensor and preventing the temperature of the protrusion or the temperature of the liquid remaining on the protrusion from affecting the detection results of the temperature sensor, but also allows the heat generated by the ejector tube to be dissipated into the cavity and outward through the cavity, preventing excessive heat concentration from affecting the measurement results of the temperature sensor, thus ensuring the accuracy of the detection results of the temperature sensor; in addition, when the temperature sensor is fixed by fasteners, the protrusion can also avoid the fasteners, thereby avoiding mutual interference.

[0007] For example, the protrusion has a top wall, the temperature sensing element has a temperature sensing surface, and there is a first distance H1 between the lower surface of the top wall and the temperature sensing surface, the first distance H1 being 4mm to 14mm. With this configuration, the first distance H1 is within this range, which not only allows the liquid remaining on the protrusion to flow to the first and second discs, further reducing the influence of the temperature of the remaining liquid on the temperature sensing element, but also prevents the temperature of the protrusion or the temperature of a small amount of liquid remaining on the protrusion from affecting the detection results of the temperature sensing element, thereby ensuring the accuracy of the detection results of the temperature sensing element.

[0008] For example, the liquid-holding tray has a first tray and a second tray, the second tray being lower than the first tray, and the first tray being closer to the center of the liquid-holding tray than the second tray. The orthographic projection of the temperature-sensing surface onto the plane of the first tray falls within the first tray, and a protrusion is disposed on the first tray. With this configuration, since the second tray is lower than the first tray, the liquid on the first tray can flow to the second tray, reducing the influence of the liquid temperature on the first tray on the temperature-sensing element. This allows the protrusion to be further away from the temperature-sensing surface, and the liquid remaining on the protrusion can flow to both the first and second trays, preventing the temperature of the protrusion or the temperature of a small amount of liquid remaining on the protrusion from affecting the detection results of the temperature-sensing element. For example, the support has a plate-shaped body, the temperature-sensing surface is in contact with the plate-shaped body, and the upper surface of the plate-shaped body is spaced apart from the lower surface of the first tray to form a first cavity, which communicates with the cavity. With this configuration, the heat generated by the ejector tube is dissipated into the first cavity and then outward through the first cavity. This further allows the heat generated by the ejector tube to be dissipated from the first cavity into the cavity and then outward through the cavity. This avoids excessive heat concentration that could affect the measurement results of the temperature sensing element, thus ensuring the accuracy of the temperature sensing element's detection results.

[0009] For example, a second distance H2 is provided between the temperature sensing surface and the lower surface of the first plate, and the second distance H2 is 5mm to 12mm. With this setting, the second distance H2 is within this range, which avoids the temperature of the first plate or the temperature of the liquid remaining on the first plate from affecting the detection result of the temperature sensing element if the first plate is too close to the temperature sensing surface, thereby ensuring the accuracy of the detection result of the temperature sensing element.

[0010] For example, the upper surface of the plate-shaped body is spaced apart from the lower surface of the second disk to form a second cavity, which is connected to the first cavity. With this configuration, the heat generated by the ejector tube can be further dissipated outward through the second cavity after being dissipated to the first cavity, thereby avoiding excessive heat concentration that could affect the measurement results of the temperature sensing element, and thus ensuring the accuracy of the temperature sensing element's detection results.

[0011] For example, a third distance H3 is provided between the temperature sensing surface and the lower surface of the second disc, and the third distance H3 is 3mm to 8mm. With this setting, the third distance H3 is within this range, which avoids the temperature of the second disc or the temperature of the liquid received by the second disc from affecting the detection results of the temperature sensing element, thereby ensuring the accuracy of the detection results of the temperature sensing element.

[0012] For example, the liquid-containing tray also has a third section, which is higher than the second section. The second section is connected between the first and third sections, and the third section encloses a third cavity that is connected to the second cavity. This arrangement allows heat dissipated into the second cavity to be further dissipated outwards through the third cavity, achieving thermal equilibrium below the liquid-containing tray. This prevents excessive heat concentration from affecting the measurement results of the temperature sensor, thus ensuring the accuracy of the temperature sensor's detection results.

[0013] For example, the temperature-sensing surface makes surface contact with the support. With this configuration, since the temperature of the support is related to the temperature of the pot bottom, the temperature of the pot bottom can be detected by sensing the temperature of the support through the temperature-sensing surface (i.e., indirectly detecting the temperature of the cookware). This not only prevents the temperature-sensing element from being affected by the flame, ensuring the accuracy of temperature detection, but also avoids interference between the temperature-sensing element and the cookware, thereby expanding the types of cookware that can be placed on the stove and broadening the applicability of the stove.

[0014] For example, the bracket has a surface to be measured, and the temperature-sensing surface is in contact with the surface to be measured. This arrangement ensures that the temperature-sensing surface and the bracket form surface contact, ensuring that the temperature-sensing element can accurately detect the temperature of the bracket through the temperature-sensing surface.

[0015] For example, the support has a plate-shaped body, through which at least part of the ejector tube passes, and the surface to be measured is disposed on the plate-shaped body. This arrangement not only facilitates the positioning of the ejector tube, but also, since the temperature of the pot bottom above the burner is transferred to the plate-shaped body through the ejector tube when the pot is heated, the temperature of the plate-shaped body is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0016] According to another aspect of this utility model, a burner is provided, which includes a flame distribution seat, a flame cap, and a burner head as described above. The flame cap and the flame distribution seat enclose a mixing chamber, which is connected to an injector tube. Since the burner head described above has the aforementioned beneficial effects, the burner including the burner head described above also has the aforementioned beneficial effects, which will not be elaborated further here.

[0017] According to another aspect of this utility model, a stove is provided, comprising a bottom shell, a panel, and a burner as described above. The bottom shell forms an open mounting cavity, the panel covers the opening, and the panel has a through hole. A liquid tray covers the through hole and has a through hole. An injector tube has a gas outlet, which passes through the mounting cavity and the through hole to communicate with a mixing chamber. Since the burner described above has the aforementioned beneficial effects, the stove including the burner also has the aforementioned beneficial effects, which will not be elaborated further here.

[0031] 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.

[0032] 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.

[0033] An embodiment of this utility model provides a burner head. The burner head provided by this utility model can be applied to a burner, which can be applied to a stove. The following will describe in detail a burner head according to an embodiment of this utility model with reference to the accompanying drawings.

[0034] See also Figures 1 to 6 The burner head 10 may include a liquid collection tray 110, an ejector tube 120, a support 130, and a temperature sensing element 140. The liquid collection tray 110 may be made of metal, which is not only easy to clean but also resistant to liquid corrosion. The support 130 may be positioned below the liquid collection tray 110. The support 130 may be made of a heat-conducting material, such as metal or other materials with good heat transfer properties. The ejector tube 120 may pass sequentially through the support 130 and the liquid collection tray 110 from bottom to top, and the ejector tube 120 may be positioned by the support 130. The temperature sensing element 140 may be mounted on the support 130. Understandably, the temperature sensing element 140 may be positioned below the liquid collection tray 110. A protrusion 111 may be formed on the liquid collection tray 110 at the location corresponding to the temperature sensing element 140. The protrusion 111 may protrude away from the temperature sensing element 140 and form a cavity 1111. The protrusion 111 can be in the shape of a disc or a box, etc.

[0035] The burner head 10 of this utility model, on the one hand, when used on a gas stove, since the temperature of the support 130 is related to the temperature of the pot bottom, and the temperature sensing element 140 is located on the support 130 below the liquid tray 110, the temperature of the pot bottom can be detected by sensing the temperature of the support 130 through the temperature sensing element 140 (i.e., indirect detection of the pot temperature). This not only prevents the temperature sensing element 140 from being affected by the flame, ensuring the accuracy of temperature detection, but also avoids interference between the temperature sensing element 140 and the pot, thereby expanding the types of pots that can be placed on the stove and broadening the applicability of the stove; on the other hand, the protrusion 111 protrudes away from the temperature sensing element 140 and forms a cavity 1111, which not only allows the liquid on the protrusion 111 to be... The liquid can flow to other parts of the liquid tray 110, reducing the influence of the liquid temperature on the protrusion 111 on the temperature sensing element 140. This avoids the temperature of the protrusion 111 (i.e., the temperature conducted from the ejector tube 120 through the liquid tray 110 to the protrusion 111) or the liquid temperature remaining on the protrusion 111 affecting the detection result of the temperature sensing element 140. Moreover, the heat generated by the ejector tube 120 can be dissipated to the cavity 1111 and dissipated outward through the cavity 1111, avoiding excessive heat concentration that could affect the measurement result of the temperature sensing element 140, thereby ensuring the accuracy of the detection result of the temperature sensing element 140. In addition, when the temperature sensing element 140 is fixed by fasteners, the protrusion 111 can also avoid the fasteners, thereby avoiding mutual interference.

[0036] See Figure 3The protrusion 111 may have a top wall 1112. The temperature sensing element 140 may have a temperature sensing surface 141. A first distance H1 may exist between the lower surface of the top wall 1112 and the temperature sensing surface 141. The first distance H1 can be 4mm to 14mm, for example, 4mm, 7mm, 9mm, 14mm, etc. Thus, within this range, the first distance H1 not only allows the liquid remaining on the protrusion 111 to flow to the first disk 112 and the second disk 113, further reducing the influence of the temperature of the remaining liquid on the temperature sensing element 140, but also avoids the temperature of the protrusion 111 or the temperature of the small amount of liquid remaining on the protrusion 111 affecting the detection result of the temperature sensing element 140, thereby ensuring the accuracy of the detection result of the temperature sensing element 140. In one embodiment of this utility model, the first distance H1 is 9mm, which effectively ensures the accuracy of the detection result of the temperature sensing element 140.

[0037] Furthermore, when the temperature sensing element 140 is fixed by fasteners, the distance between the lower surface of the top wall 1112 and the top of the fastener can be greater than 1 mm, such as 1 mm, 1.5 mm, or 2 mm. This effectively avoids interference between the protrusion 111 and the fastener. In one embodiment of this invention, the distance between the tops of the fasteners is 1.5 mm, which effectively ensures that the protrusion 111 and the fastener do not interfere with each other.

[0038] See also Figure 3 and Figure 6 The liquid-holding tray 110 may have a first tray portion 112 and a second tray portion 113. The second tray portion 113 may be lower than the first tray portion 112. The first tray portion 112 may be closer to the center of the liquid-holding tray 110 than the second tray portion 113. The temperature-sensing surface 141 may have its orthographic projection onto the plane containing the first tray portion 112 falling within the first tray portion 112. A protrusion 111 may be provided on the first tray portion 112. Thus, since the second tray portion 113 is lower than the first tray portion 112, the liquid on the first tray portion 112 can flow to the second tray portion 113, reducing the influence of the liquid temperature on the first tray portion 112 on the temperature-sensing element 140. This allows the protrusion 111 to be further away from the temperature-sensing surface 141, and the liquid remaining on the protrusion 111 can flow to the first tray portion 112 and the second tray portion 113, avoiding the temperature of the protrusion 111 or the temperature of the small amount of liquid remaining on the protrusion 111 from affecting the detection result of the temperature-sensing element 140.

[0039] Specifically, in conjunction with reference Figures 3 to 6The ejector tube 120 may include an inner ring ejector tube 121 and an outer ring ejector tube 122. Since the inner ring ejector tube 121 is centered for convenient flame control, and the outer ring ejector tube 122 is further from the center than the inner ring ejector tube 121, it helps to expand the combustion range. Therefore, the inner ring ejector tube 121 is positioned closer to the center of the liquid-holding tray 110 than the outer ring ejector tube 122. Because the first tray portion 112 is positioned close to the center of the liquid-holding tray 110, the inner ring ejector tube 121 can pass through the first tray portion 112. A first hole 1121 may be provided on the first tray portion 112, and the inner ring ejector tube 121 can pass through the first hole 1121. The first tray portion 112 is higher than the second tray portion 113, allowing liquid on the first tray portion 112 to flow towards the second tray portion 113, reducing the amount of liquid on the first tray portion 112 flowing into the liquid-holding tray 110 from the first hole 1121 and affecting the detection of the temperature sensing element 140. To further prevent liquid from flowing into the liquid collection tray 110 from the first hole 1121, a leak-proof structure, such as a flange or a seal, can be provided between the inner ring ejector tube 121 and the first tray 112. To accommodate the positional relationship between the inner ring ejector tube 121 and the outer ring ejector tube 122, the outer ring ejector tube 122 can pass through the second tray 113. A second hole 1131 can be provided on the second tray 113, through which the outer ring ejector tube 122 can pass. To prevent liquid from flowing into the liquid collection tray 110 from the second hole 1131, a leak-proof structure, such as a flange or a seal, can also be provided between the outer ring ejector tube 122 and the second tray 113.

[0040] A first connecting portion 116 may be provided between the first plate portion 112 and the second plate portion 113. The first connecting portion 116 may be inclined or arc-shaped to better guide the liquid from the first plate portion 112 to the second plate portion 113. (See again) Figure 3The support 130 may have a plate-shaped body 132. A temperature-sensing surface 141 may contact the plate-shaped body 132. The temperature-sensing surface 141 may be attached to the plate-shaped body 132 so that it can directly detect the heat of the plate-shaped body 132. Alternatively, the temperature-sensing surface 141 may be fixed to the plate-shaped body 132 by a heat-conducting element, allowing it to transfer heat to detect the heat of the plate-shaped body 132. The temperature-sensing surface 141 may be disposed on the lower surface of the plate-shaped body 132. The upper surface of the plate-shaped body 132 and the lower surface of the first disk portion 112 may be spaced apart to form a first cavity 151. The first cavity 151 may communicate with the cavity 1111. In this way, the heat generated by the ejector tube 120 is dissipated into the first cavity 151 and then outward through the first cavity 151. Furthermore, the heat generated by the ejector tube 120 is dissipated from the first cavity 151 into the cavity 1111 and then outward through the cavity 1111. This avoids excessive heat concentration that could affect the measurement results of the temperature sensing element 140, thus ensuring the accuracy of the detection results of the temperature sensing element 140. Furthermore, the support 130 may also have a support leg 133, which can be used to support the plate-shaped body 132, thereby ensuring that the ejector tube 120 can be positioned by the support 130.

[0041] See again Figure 3 A second distance H2 can be provided between the temperature-sensing surface 141 and the lower surface of the first disc portion 112. This second distance H2 can be 5mm to 12mm, for example, 5mm, 7.5mm, 10mm, or 12mm. Within this range, the second distance H2 avoids the temperature of the first disc portion 112 or the temperature of the liquid remaining on it affecting the detection result of the temperature-sensing element 140, thus ensuring the accuracy of the detection result. In one embodiment of this invention, the second distance H2 is 7.5mm, which effectively ensures the accuracy of the detection result of the temperature-sensing element 140.

[0042] See again Figure 3 The upper surface of the plate-shaped body 132 and the lower surface of the second disk portion 113 can be spaced apart to form a second cavity 152. The second cavity 152 can be connected to the first cavity 151. In this way, the heat generated by the ejector tube 120, after being dissipated to the first cavity 151, can be further dissipated outward through the second cavity 152, thereby avoiding excessive heat concentration that would affect the measurement results of the temperature sensing element 140, and thus ensuring the accuracy of the detection results of the temperature sensing element 140.

[0043] See again Figure 3A third distance H3 can be provided between the temperature-sensing surface 141 and the lower surface of the second disc portion 113. This third distance H3 can be 3mm to 8mm, for example, 3mm, 4.6mm, 6mm, or 8mm. Within this range, the temperature of the second disc portion 113 or the temperature of the liquid it receives prevents the temperature sensor 140 from affecting its detection results, thus ensuring the accuracy of the detection results. In one embodiment of this invention, the third distance H3 is 4.6mm, which effectively ensures the accuracy of the temperature sensor 140's detection results.

[0044] See again Figure 3 The liquid-holding tray 110 may also have a third tray 114. The third tray 114 may be higher than the second tray 113. The second tray 113 may be connected between the first tray 112 and the third tray 114. The third tray 114 may enclose a third cavity 153. The third cavity 153 may be connected to the second cavity 152. In this way, the heat dissipated into the second cavity 152 can be further dissipated outward through the third cavity 153, so that the area below the liquid-holding tray 110 can reach thermal equilibrium, thereby avoiding excessive heat concentration that would affect the measurement results of the temperature sensing element 140, and thus ensuring the accuracy of the detection results of the temperature sensing element 140. Furthermore, a second connecting portion 117 may be provided between the second tray 113 and the third tray 114. The second connecting portion 117 may also be inclined or arc-shaped to better guide the liquid from the third tray 114 to the second tray 113. A liquid-holding cavity 115 can be formed at the second plate section 113 to catch liquids that splash during cooking, preventing liquids from flowing everywhere and affecting the operation of other components.

[0045] See also Figure 3 , Figure 4 , Figure 5 and Figure 7 The temperature-sensing surface 141 and the support 130 can form surface contact. Since the temperature of the support 130 is related to the temperature of the pot bottom, sensing the temperature of the support 130 through the temperature-sensing surface 141 enables the detection of the pot bottom temperature (i.e., indirect detection of the pot temperature). This not only prevents the temperature-sensing element 140 from being affected by the flame, ensuring accurate temperature detection, but also avoids interference between the temperature-sensing element 140 and the pot, thereby expanding the types of pots that can be placed on the stove and broadening the applicability of the stove.

[0046] See also Figure 3 and Figure 7 The bracket 130 may have a test surface 131, and the temperature sensing surface 141 may be in contact with the test surface 131. In this way, the temperature sensing surface 141 and the bracket 130 are in surface contact, ensuring that the temperature sensing element 140 can accurately detect the temperature of the bracket 130 through the temperature sensing surface 141.

[0047] See also Figure 4 , Figure 5 and Figure 7 The support 130 may have a plate-shaped body 132. The ejector tube 120 may at least partially extend through the plate-shaped body 132. The surface to be measured 131 may be disposed on the plate-shaped body 132. This not only facilitates the positioning of the ejector tube 120, but also, since the temperature of the pot bottom above the burner 10 is transferred to the plate-shaped body 132 through the ejector tube 120 when the pot is heated, the temperature of the plate-shaped body 132 is correlated with the temperature of the pot bottom, ensuring the accuracy and speed of temperature detection.

[0048] For example, the temperature sensing element 140 can be connected to the bracket 130 via fasteners to ensure that the temperature sensing surface 141 is in close contact with the surface to be measured 131. This ensures the stability of the connection between the temperature sensing element 140 and the bracket 130 and guarantees good surface contact. The fasteners can be screws, bolts, etc. In embodiments not shown, the temperature sensing element 140 can also be connected to the bracket 130 by other means, such as welding, riveting, gluing, or snap-fit ​​connection.

[0049] For example, the temperature sensor 140 can be located above or below the bracket 130, ensuring that the temperature sensor 140 can accurately detect the temperature of the bracket 130. Depending on the size of the burner 10 or the usage scenario, the temperature sensor 140 can be set in a suitable position, expanding the applicability of the stove.

[0050] See again Figure 3 and Figure 7 The temperature-sensing surface 141 can be attached to the lower surface of the plate-shaped body 132. The upper surface of the plate-shaped body 132 and the lower surface of the second disc portion 113 can have a fourth distance H4. The plate-shaped body 132 can have a thickness h, where H4 = H3 - h. In this way, on the one hand, the surface to be measured 131 is located on the lower surface of the plate-shaped body 132, which not only avoids the influence of flame combustion on temperature detection and ensures the accuracy of temperature detection, but also effectively prevents leaked soup from contacting the temperature-sensing element 140 and affecting the accuracy and service life of the temperature-sensing element 140. On the other hand, through the second cavity 152 formed between the upper surface of the plate-shaped body 132 and the lower surface of the second disc portion 113, the heat generated by the ejector tube 120 can be further dissipated outward, thereby avoiding excessive heat concentration that would affect the measurement results of the temperature-sensing element 140.

[0051] The thickness h can be from 0.5mm to 3mm, for example, 0.5mm, 1mm, 2mm, 3mm, etc. Within this range, the thickness h ensures the accuracy of temperature detection by the temperature sensing element 140 and the strength of the plate-shaped body 132. This avoids both excessively thin plate-shaped body 132 (which would result in poor strength) and excessively thick plate-shaped body 132 (which would slow down the temperature conduction to the temperature sensing element 140 and affect its temperature detection). In one embodiment of this invention, the thickness h is 1mm, which effectively ensures the accuracy of temperature detection by the temperature sensing element 140.

[0052] Specifically, in conjunction with reference Figures 1 to 8 When the burner head 10 is applied to a stove, the temperature sensing element 140 can be a temperature sensor. The temperature sensing element 140 may have a sheet-like portion 142 and a lead portion 143. The sheet-like portion 142 may be made of a thermally conductive material, such as metal or other materials with good thermal conductivity. The temperature sensing surface 141 may be located on the sheet-like portion 142 to ensure that the temperature sensing element 140 can accurately detect the temperature of the bracket 130 through the temperature sensing surface 141. The lead portion 143 may include a probe body 1431 connected to the sheet-like portion 142. The probe body 1431 may contain a negative temperature coefficient thermistor, etc., which is not limited here, as long as it can convert temperature information into other output or judgment signals. In this way, the temperature sensor 140 can monitor the temperature in real time and compare it with the preset temperature threshold. If the temperature of the bottom of the pot is higher than the preset temperature threshold, it is determined that dry burning has occurred; or it can collect temperature information for a period of time, calculate the temperature change rate during that period, and automatically select the threshold for activating the anti-dry burning function based on the temperature change rate. Finally, if the temperature change of the bottom of the pot is higher than the threshold, it is determined that dry burning has occurred, and then the gas supply is cut off to prevent combustion.

[0053] The following explanation uses a negative temperature coefficient thermistor as an example. Under normal heating conditions, the temperature change rate of a negative temperature coefficient thermistor is relatively stable. However, when the cookware is dry-burned, the temperature of the cookware will rise rapidly due to insufficient medium to absorb heat, and the temperature of the support 130 will also rise rapidly, causing the temperature change rate of the negative temperature coefficient thermistor to increase sharply.

[0054] Negative temperature coefficient (NTC) thermistors exhibit a temperature-resistance characteristic curve. When the temperature of an NTC thermistor increases, the steeper slope of its temperature-resistance characteristic curve indicates that the thermistor is under continuous heating, thus confirming that the cookware is dry-heated. NTC thermistors respond quickly to temperature changes and have high sensitivity, providing accurate temperature measurements. Furthermore, NTC thermistors are simple in structure, low in cost, have a low failure rate, and exhibit good long-term stability. Their high heat transfer efficiency and sensitive response to temperature changes, combined with their simple structure and low operating cost, effectively reduce the failure rate and operating costs of cookware, thereby improving its reliability.

[0055] In some embodiments, the probe body 1431 may contain a thermally conductive medium. This allows the temperature of the support 130 to be transferred to the negative temperature coefficient thermistor more effectively and accurately, thereby further improving the accuracy and speed of temperature detection. Specifically, the thermally conductive medium can be a thermally conductive resin. Thermally conductive resin not only has high thermal conductivity but also stability. Filling the probe body 1431 with thermally conductive resin can effectively improve the accuracy and speed of temperature detection. Of course, the thermally conductive medium can also be other materials.

[0056] Furthermore, the lead portion 143 may also include a signal transmission line 1432 connected to the end of the probe body 1431 away from the sheet portion 142. This not only facilitates the conversion of the temperature information collected by the sheet portion 142 into an output signal for transmission, but also prevents the signal transmission line 1432 from being affected by high temperatures, as it is relatively far from the sheet portion 142. Specifically, the signal transmission line 1432 may be covered with a protective sleeve. The protective sleeve further prevents high temperatures from affecting the signal transmission line 1432 and also avoids the problem of the signal transmission line 1432 being easily damaged when exposed.

[0057] In an embodiment not shown, the end of the signal transmission line 1432 furthest from the probe body 1431 can be connected to a controller. The temperature information collected by the temperature sensing element 140 by the plate-shaped portion 142 is converted into a signal by a negative temperature coefficient thermistor and transmitted to the controller via the signal transmission line 1432. The controller can control the working status of the stove based on this signal. When the controller determines that the stove is in a state of dry burning, accidental flameout, or prolonged high flame without placing the pot on it, it can immediately cut off the gas supply to extinguish the stove and avoid safety hazards.

[0058] According to another aspect of the present invention, a burner 1 is provided. (See also...) Figures 2 to 5The burner 1 may include a flame distribution seat 11, a flame cap 12, and a burner head 10 as described above. The flame cap 12 and the flame distribution seat 11 may be closed to form a mixing chamber 13. The mixing chamber 13 may be connected to the injector tube 120. Since the burner head 10 described above has the aforementioned beneficial effects, the burner 1 including the burner head 10 described above also has the aforementioned beneficial effects, which will not be described in detail here.

[0059] Furthermore, the burner cap 12 may include an outer ring burner cap and an inner ring burner cap. The outer ring burner cap is located at the outermost layer of the burner 1, providing a wide heating area. The inner ring burner cap is located inside the outer ring burner cap, forming a central flame area for concentrated heating, and together with the outer ring burner cap, forming at least two rings of flame. The corresponding burner base 11 may include a large burner base and a small burner base. The outer ring burner cap may be placed on the large burner base, and the inner ring burner cap may be placed on the small burner base. The burner 1 may also typically include a pot support 14. The pot support 14 may be disposed around the outer periphery of the outer ring burner cap. The pot support 14 may be supported on the liquid tray 110. The pot may be placed on the pot support 14. When the user turns on the burner 1, the combustible gas ejected from the burner base 11 can be ignited by the ignition needle to form a flame, and the flame can diffuse through the gaps in the burner cap 12 to form a flame ring, thereby heating the pot.

[0060] According to another aspect of this utility model, a stove is provided. (See also...) Figures 1 to 3 The stove may include a bottom shell 3, a panel 2, and a burner 1 as described above. The bottom shell 3 may form a mounting cavity 31 with an opening 32. The panel 2 may cover the opening 32. The panel 2 may have a through hole 20. A liquid tray 110 may cover the through hole 20. The liquid tray 110 may have a through hole. Understandably, the through hole may include a first hole 1121 and a second hole 1131. The ejector tube 120 may have a gas outlet 123. The gas outlet 123 can pass through the mounting cavity 31 through the through hole and communicate with the mixing chamber 13. Since the burner 1 described above has the above-mentioned beneficial effects, the stove including the burner 1 described above also has the above-mentioned beneficial effects, which will not be described in detail here.

[0061] Furthermore, the third cavity 153 can be formed by the lower surface of the third disc portion 114 and the upper surface of the panel 2. A fifth distance H5 can exist between the third disc portion 114 and the panel 2, which can be 2mm to 7mm, for example, 2mm, 4.8mm, 6mm, or 7mm. In this way, the ejector tube 120 dissipates heat sequentially from the first cavity 151, the second cavity 152, and the third cavity 153. Heat can also be dissipated from the first cavity 151 into the cavity 1111, thus achieving thermal equilibrium below the liquid-filled tray 110. This prevents excessive heat concentration from affecting the measurement results of the temperature sensing element 140, thereby ensuring the accuracy of the detection results of the temperature sensing element 140. In one embodiment of this invention, the fifth distance H5 is 4.8mm, which effectively ensures the accuracy of the detection results of the temperature sensing element 140.
