Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the range, specifically, a range. BACKGROUND

[0002] With the use rate of gas range being higher and higher, people's requirement for the safety of the range is also higher and higher. The gas range will be usually provided with an external temperature sensing probe, which can detect the temperature of the bottom of the pot, and when the temperature of the bottom of the pot exceeds the preset temperature, it will automatically extinguish the flame to protect; at the same time, when the range is accidentally extinguished and the pot is not placed for a long time, the gas source can also be cut off in the first time based on the detection result of the external temperature sensing probe to avoid accidents.

[0003] However, the external temperature sensing probe has certain limitations in the use process, such as: because the external temperature sensing probe needs to be in contact with the bottom of the pot, in order to avoid interference with the external temperature sensing probe, only flat-bottomed pots can be used for cooking; in addition, the external temperature sensing probe is easily affected by the flame, which causes the external temperature sensing probe to be unable to accurately detect the temperature of the bottom of the pot, resulting in the range being abnormally determined to extinguish the flame.

[0004] If the temperature sensing probe is arranged on the bottom shell, although it can avoid contact with the bottom of the pot, since the temperature sensing probe will generate heat when working, a large amount of heat is easy to accumulate in the bottom shell, which affects the detection accuracy and service life of the temperature sensing part. UTILITY MODEL CONTENT

[0005] In order to at least partially solve the problems existing in the prior art, according to one aspect of the utility model, a range is provided, and the technical scheme is as follows.

[0006] The range comprises a bottom shell, a panel, a burner and a temperature sensing part. The bottom shell encloses an installation cavity with an opening, the panel is arranged on the bottom shell and covers the opening, a part of the burner is arranged in the installation cavity, and the temperature sensing part is connected with the burner and located in the installation cavity. The bottom shell has a cavity bottom wall, the cavity bottom wall is arranged opposite to the panel, the cavity bottom wall has a first area, the projection of the temperature sensing part on the plane of the cavity bottom wall is located in the first area, and the first area is provided with a heat dissipation hole.

[0007] The range of the utility model can sense the temperature of the burner through the temperature sensing part to realize pot bottom temperature detection, the temperature sensing part is arranged in the installation cavity, the temperature sensing part will not be affected by the flame, even in the case of using a pointed-bottom pot, the temperature sensing part will not interfere with the pot, thereby expanding the application range of the range. In addition, the cavity bottom wall of the bottom shell is formed with a heat dissipation hole, the position of the heat dissipation hole is close to the temperature sensing part, the heat generated by the temperature sensing part can also be discharged through the heat dissipation hole, thereby avoiding affecting and damaging the temperature sensing part, effectively improving the detection accuracy and service life of the temperature sensing part, and improving the safety and reliability of the range.

[0008] Exemplarily, the temperature sensing element has a sensing surface, and the sensing surface has a first distance Z of 40mm-68mm from the first area in a direction perpendicular to the panel. In this way, the sensing surface has the above-mentioned first distance range from the first area, which not only ensures that the heat generated by the temperature sensing element during operation can be discharged through the heat dissipation hole, but also avoids the heat of the burner being rapidly lost through the heat dissipation hole, thereby causing inaccurate sensing results of the temperature sensing element, and effectively improving the reliability and accuracy of the temperature sensing element.

[0009] Exemplarily, the burner includes an ejector pipe and a bracket, the ejector pipe is arranged in the bracket, and the ejector pipe is positioned by the bracket. In this way, by mounting the ejector pipe on the bracket, the overall structural design of the burner can be optimized to be more compact and stable. Moreover, the ejector pipe can be positioned by the bracket, which simplifies the assembly process of the burner, reduces the assembly steps and time, and is convenient for subsequent maintenance and replacement, thereby greatly reducing the maintenance cost.

[0010] Exemplarily, the temperature sensing element is arranged on the bracket. The temperature of the bracket can be sensed by the temperature sensing element to realize the detection of the temperature of the pot bottom (i.e., indirect detection of the temperature of the cookware), which not only ensures that the temperature sensing element can sense the temperature of the pot bottom in real time, but also avoids the interference or damage of the temperature sensing element caused by the close distance between the temperature sensing element and the flame of the burner, effectively improves the accuracy of the sensing result of the temperature sensing element, and further improves the safety and reliability of the use of the cooktop.

[0011] Exemplarily, at least part of the temperature sensing element forms surface contact with the bracket. In this way, the surface contact can significantly increase the contact area between the temperature sensing element and the bracket, thereby reducing the contact thermal resistance, allowing the heat on the bracket to be quickly and uniformly transmitted to the temperature sensing element, further improving the accuracy of the sensing result of the temperature sensing element, and further improving the safety and reliability of the use of the cooktop.

[0012] Exemplarily, the temperature sensing element is arranged on the ejector pipe. The temperature of the ejector pipe can be sensed by the temperature sensing element to realize the detection of the temperature of the pot bottom (i.e., indirect detection of the temperature of the cookware), which not only ensures that the temperature sensing element can sense the temperature of the pot bottom in real time, but also avoids the interference or damage of the temperature sensing element caused by the close distance between the temperature sensing element and the flame of the burner, effectively improves the accuracy of the sensing result of the temperature sensing element, and further improves the safety and reliability of the use of the cooktop.

[0013] Exemplarily, at least part of the temperature sensing element forms surface contact with the ejector pipe. In this way, the temperature sensing element can directly form surface contact with the outer surface of the ejector pipe, which not only ensures that the temperature sensing element can sense the temperature of the ejector pipe, but also simplifies the connection mode between the temperature sensing element and the ejector pipe, and facilitates the disassembly of the temperature sensing element when the temperature sensing element needs to be repaired or replaced, thereby effectively improving the convenience of the use of the operator.

[0014] Exemplarily, the heat pipe is connected with the heat transfer member, and the temperature sensing member is arranged on the heat transfer member. In this way, the temperature sensing member can be in contact with the heat transfer member, and when the stove is in the combustion state, the temperature of the heat transfer member is related to the temperature of the pot bottom, and the temperature of the pot bottom can be detected by sensing the temperature of the heat transfer member through the temperature sensing member (i.e., indirectly detecting the temperature of the pot), and the temperature sensing member is not affected by the flame, which not only ensures the accuracy and rapidity of temperature detection, but also ensures that the temperature sensing member will not interfere with the pot even in the case of using a pointed bottom pot, thereby expanding the application range of the stove and effectively improving the practicability of the stove.

[0015] Exemplarily, at least part of the temperature sensing member is in surface contact with the heat transfer member. In this way, the temperature sensing member can be in direct surface contact with the heat transfer member, which not only ensures that the temperature sensing member can sense the temperature of the heat transfer member, but also simplifies the connection mode between the temperature sensing member and the heat transfer member, and when the temperature sensing member needs to be repaired or replaced, the temperature sensing member can be conveniently disassembled, thereby effectively improving the convenience of use for the operator.

[0016] Exemplarily, the projection of the support towards the plane where the cavity bottom wall is located is located in the first area. In this way, the support can be arranged close to the heat dissipation hole, and the heat transferred to the support and the heat generated by the components on the support can be discharged through the heat dissipation hole, thereby effectively avoiding the accumulation of heat in the mounting cavity and effectively improving the safety and reliability of the stove in use.

[0017] Exemplarily, the heat dissipation hole is a circular hole, the temperature sensing member has a sensing surface, and the projection of the sensing surface towards the plane where the cavity bottom wall is located is located in the circular hole. In this way, the sensing surface of the temperature sensing member can be located directly above the heat dissipation hole, and the heat generated by the temperature sensing member can be discharged through the heat dissipation hole in the first time, thereby ensuring that the temperature sensing member can always be in a stable and suitable working environment temperature, effectively improving the sensing accuracy and service life of the temperature sensing member, and further improving the safety and reliability of the stove in use.

DETAILED DESCRIPTION

[0034] In the following description, numerous specific details are provided in order to provide a thorough understanding of the present application. One of ordinary skill in the art will realize, however, that the application can be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order not to unnecessarily obscure the present application.

[0035] In order to thoroughly understand the embodiments of the present application, detailed structures will be proposed in the following description. Obviously, the implementation of the embodiments of the present application is not limited to the special details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail as follows, however, in addition to these detailed descriptions, the present application can also have other embodiments.

[0036] One embodiment of the present application provides a stove 10 which can protect the temperature sensing piece 140 from heat and damage, effectively improve the sensitivity and service life of the temperature sensing piece 140, and further improve the safety and reliability of the use of the stove 10. Hereinafter, a stove 10 according to an embodiment of the present application will be described in detail with reference to the accompanying drawings.

[0037] In combination with reference to Figure 1 , Figure 2 and Figure 3 , the stove 10 includes a bottom shell 110, a panel 120, a burner 130, and a temperature sensing piece 140. The bottom shell 110 encloses a mounting cavity 1110 with an opening, the panel 120 is arranged on the bottom shell 110 and covers the opening, a part of the burner 130 is arranged in the mounting cavity 1110, and the temperature sensing piece 140 is connected with the burner 130 and located in the mounting cavity 1110. Among them, the bottom shell 110 has a cavity bottom wall 1111, the cavity bottom wall 1111 is arranged opposite to the panel 120, the cavity bottom wall 1111 has a first region 1112, the projection of the temperature sensing piece 140 towards the plane where the cavity bottom wall 1111 is located is located in the first region 1112, and the first region 1112 is provided with a heat dissipation hole 150.

[0038] 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 the mounting cavity 1110, the burner 130 can be arranged in the mounting cavity 1110, and part of the burner 130 can be extended out of the mounting cavity 1110 through the through hole to heat the pot and other objects.

[0039] Referring to Figure 5 , the temperature sensing piece 140 can include a heat conduction part 1410, a sensing part 1420, and a signal transmission line 1430, two ends of the sensing part 1420 can be connected with the heat conduction part 1410 and the signal transmission line 1430 respectively, the heat conduction part 1410 can transmit the heat generated by the burner 130 to the sensing part 1420, the sensing part 1420 can convert the heat into temperature information and transmit it to the outside through the signal transmission line 1430.

[0040] Further, the heat conduction part 1410 can be made of copper or aluminum or other materials with good heat conduction, and the application does not make specific limitation on the material of the heat conduction part 1410, and any material with good heat conduction performance can be used. In addition, the shape of the heat conduction part 1410 can be determined according to different use scenarios and use requirements. For example, the shape of the heat conduction part 1410 can be circular, square or irregular, and the application does not make specific limitation on the shape of the heat conduction part 1410.

[0041] Referring to Figure 2 and Figure 3 , the first area 1112 can be formed on the cavity bottom wall 1111, and the heat generated by the temperature sensing piece 140 can be discharged from the mounting cavity 1110 in time through the heat dissipation hole 150 arranged on the first area 1112. In addition, the temperature sensing piece 140 is located above the first area 1112, so that the hot air flow in the mounting cavity 1110 can be quickly discharged along a shorter air flow path, avoiding the overheating phenomenon that may occur due to the heat concentration in the area near the temperature sensing piece 140.

[0042] Specifically, the heat dissipation hole 150 can be in communication with the mounting cavity 1110, so that the mounting cavity 1110 is in communication with the external environment. The shape and heat dissipation area of the heat dissipation hole 150 can be determined according to actual use needs, and the application does not make specific limitation thereon. For example, the shape of the heat dissipation hole 150 can be strip-shaped or circular.

[0043] In an embodiment not shown, the number of heat dissipation holes 150 can be multiple, and multiple heat dissipation holes 150 can be arranged on the first area 1112 at intervals.

[0044] The temperature sensing piece 140 is arranged in the mounting cavity 1110, the temperature sensing piece 140 is not affected by the flame, even in the case of using a sharp bottom pot, the temperature sensing piece 140 also does not interfere with the pot, and the application range of the stove 10 is expanded. In addition, the bottom wall 1111 of the bottom shell 110 is formed with a heat dissipation hole 150, the position of the heat dissipation hole 150 is close to the temperature sensing piece 140, heat generated by the temperature sensing piece 140 can also be discharged through the heat dissipation hole 150, the temperature sensing piece 140 is avoided from being affected and damaged, the detection accuracy and service life of the temperature sensing piece 140 are effectively improved, and the safety and reliability of the stove 10 are improved.

[0045] In some embodiments, referring to Figure 4 The temperature sensing piece 140 has a sensing surface 1411, and the sensing surface 1411 and the first area 1112 have a first distance Z in a direction perpendicular to the panel 120, and the first distance Z is 40mm-68mm. In this way, the sensing surface 1411 and the first area 1112 have the above-mentioned first distance range, which not only ensures that the heat generated by the temperature sensing piece 140 during work can be discharged through the heat dissipation hole 150, but also avoids the heat of the burner 130 from being quickly lost through the heat dissipation hole 150, thereby causing the sensing result of the temperature sensing piece 140 to be inaccurate, and effectively improving the reliability and accuracy of the temperature sensing piece 140.

[0046] The sensing surface 1411 can be formed on the heat-conducting part 1410 of the temperature sensing piece 140, and the sensing surface 1411 can be connected with the burner 130 to transfer the heat of the burner 130 to the temperature sensing piece 140.

[0047] Specifically, the first distance Z is 40mm-68mm, for example, 40mm, 50mm, 54mm, 60mm, 68mm, etc., and is preferably 54mm.

[0048] The distance between the sensing surface 1411 and the first area 1112 should not be too large or too small. When the first distance is too large, the heat generated by the temperature sensing piece 140 during work cannot be discharged through the heat dissipation hole 150, so that the heat generated by the temperature sensing piece 140 accumulates in the mounting cavity 1110, thereby damaging the temperature sensing piece 140. When the first distance is too small, the heat of the burner 130 can be quickly discharged through the heat dissipation hole 150, thereby affecting the sensing result of the temperature sensing piece 140. Specifically, it can cause the value sensed by the temperature sensing piece 140 to be low, and cannot accurately reflect the actual value sensed, thereby affecting the accuracy of the sensing result of the temperature sensing piece 140.

[0049] In some embodiments, in combination with referring to Figure 3 ,Figure 6 、 Figure 8 、 Figure 9 and Figure 10 The furnace head 130 comprises an ejector pipe 1310 and a bracket 1320, the ejector pipe 1310 is arranged in the bracket 1320, and the ejector pipe 1310 is positioned by the bracket 1320. In this way, by mounting the ejector pipe 1310 on the bracket 1320, the overall structural design of the furnace head 130 can be optimized to be more compact and stable. Moreover, the ejector pipe 1310 can be positioned by the bracket 1320, which also simplifies the assembly process of the furnace head 130, reduces the assembly steps and time, and is convenient for subsequent maintenance and replacement, greatly reducing the maintenance cost.

[0050] Specifically, the number and type of the ejector pipe 1310 can be determined according to the type of the furnace head 130. For example, Figure 6 the furnace head 130 shown in Figure 6 is a double-ring furnace head, when the furnace head 130 is a double-ring furnace head, the ejector pipe 1310 can comprise an inner ring ejector pipe 1311 and an outer ring ejector pipe 1312. When the furnace head 130 is a three-ring furnace head, the ejector pipe 1310 can comprise an inner ring ejector pipe 1311, a middle ring ejector pipe, and an outer ring ejector pipe 1312. One end of the ejector pipe 1310 can be connected in communication with the gas source, and the other end of the ejector pipe 1310 can be arranged in the bracket 1320.

[0051] Referring to Figure 7 , the bracket 1320 can have a plate body 1321 and a leg 1322. One end of the leg 1322 can be arranged on the plate body 1321. The end of the leg 1322 away from the plate body 1321 can form a connecting end 1323, which can be fixedly connected to the bottom shell 110 of the cooktop 10 to realize the fixation of the furnace head 130.

[0052] In some embodiments, referring to Figure 7 , the temperature sensing piece 140 is arranged on the bracket 1320. The temperature sensing piece 140 can realize the detection of the temperature of the pot bottom (i.e., indirectly detect the temperature of the pot) by sensing the temperature of the bracket 1320. In this way, not only can the temperature sensing piece 140 sense the temperature of the pot bottom in real time, but also can avoid the situation that the temperature sensing piece 140 is disturbed or damaged due to the close distance between the temperature sensing piece 140 and the flame of the furnace head 130, effectively improving the accuracy of the temperature sensing result of the temperature sensing piece 140, and further improving the safety and reliability of the use of the cooktop 10.

[0053] The temperature sensing element 140 can be arranged on the support 1320 so that the temperature sensing element 140 can form a surface contact with the support 1320. Since the temperature of the bottom of the pot above the burner head 130 can be transferred to the support 1320 when the pot is heated, the temperature of the support 1320 is associated with the temperature of the bottom of the pot, so that the temperature sensing element 140 can determine the temperature of the bottom of the pot by sensing the temperature of the support 1320. Specifically, the support 1320 can be made of a material with good thermal conductivity, such as stainless steel.

[0054] Referring to Figure 7 and Figure 8 , the temperature sensing element 140 can be detachably connected to the support 1320 by the fastener 170. The fastener 170 can be a bolt or a screw, etc. The above-described detachable connection can enable the temperature sensing element 140 to be quickly installed on the support 1320, effectively saving the installation time and cost of the temperature sensing element 140. Moreover, when the temperature sensing element 140 needs to be replaced or maintained, the temperature sensing element 140 can be conveniently disassembled and assembled, greatly reducing the workload and cost required for disassembling and assembling the temperature sensing element 140.

[0055] In an embodiment not shown, the temperature sensing element 140 can also be connected to the support 1320 in other ways, such as welding, riveting, pasting, buckle connection, etc.

[0056] In some embodiments, referring to Figure 5 and Figure 7 , at least part of the temperature sensing element 140 forms a surface contact with the support 1320. In this way, the surface contact can significantly increase the contact area between the temperature sensing element 140 and the support 1320, thereby reducing the contact thermal resistance, enabling the heat on the support 1320 to be quickly and uniformly transferred to the temperature sensing element 140, further improving the accuracy of the sensing result of the temperature sensing element 140, and thereby improving the safety and reliability of the cooktop 10.

[0057] Specifically, the sensing surface 1411 of the temperature sensing element 140 can form a surface contact with the support 1320 to ensure that the sensing surface 1411 and the support 1320 have sufficient contact area, and thereby the heat of the support 1320 can be quickly and efficiently transferred to the temperature sensing element 140. Moreover, the surface contact can make the connection between the temperature sensing element 140 and the support 1320 more firm, avoiding the situation that the connection between the temperature sensing element 140 and the support 1320 is not tight or even loose when the cooktop 10 is vibrated or subjected to external force, further improving the reliability of the temperature sensing element 140.

[0058] In some embodiments, referring to Figure 9The temperature sensing piece 140 is arranged on the ejector pipe 1310. The temperature of the pot bottom can be detected by sensing the temperature of the ejector pipe 1310 (i.e., indirectly detecting the temperature of the pot), which not only ensures that the temperature sensing piece 140 can sense the temperature of the pot bottom in real time, but also avoids the situation that the temperature sensing piece 140 is interfered or damaged due to the close distance between the temperature sensing piece 140 and the flame of the burner 130, effectively improves the accuracy of temperature sensing of the temperature sensing piece 140, and further improves the safety and reliability of the use of the cooktop 10.

[0059] Specifically, the ejector pipe 1310 can include an inner ring ejector pipe 1311 and an outer ring ejector pipe 1312, and the temperature sensing piece 140 can be attached to one or more of the above ejector pipes 1310, preferably attached to the inner ring ejector pipe 1311.

[0060] Since the temperature of the pot bottom above the burner 130 can be transmitted to the ejector pipe 1310 when the pot is heated, the temperature of the ejector pipe 1310 is associated with the temperature of the pot bottom, so that the temperature sensing piece 140 can determine the temperature of the burner 130 by sensing the temperature of the ejector pipe 1310. Specifically, the ejector pipe 1310 can be made of a heat-conducting material, for example, the material of the ejector pipe 1310 can be metal or other materials with good heat transfer performance, so that the temperature sensing piece 140 can sense the temperature of the ejector pipe 1310.

[0061] In some embodiments, referring to Figure 9 Therefore, the temperature sensing piece 140 can be in direct surface contact with the outer surface of the ejector pipe 1310, which not only ensures that the sensing piece can sense the temperature of the ejector pipe 1310, but also simplifies the connection mode between the sensing piece and the ejector pipe 1310. When the temperature sensing piece 140 needs to be repaired or replaced, the temperature sensing piece 140 can be conveniently disassembled, effectively improving the convenience of use of the operator.

[0062] The shape of the heat-conducting part 1410 of the temperature sensing piece 140 can be adapted to the outer contour of the ejector pipe 1310. Specifically, the shape of the heat-conducting part 1410 can be arc-shaped plate-shaped, so that not only the heat-conducting part 1410 and the ejector pipe 1310 have sufficient contact area, but also the above two can be closely attached. The sensing surface 1411 can be formed on the side of the heat-conducting part 1410 that is attached to the outer surface of the ejector pipe 1310.

[0063] The sensing surface 1411 of the heat-conducting part 1410 and the outer surface of the ejector pipe 1310 can be in contact through bonding connection or clamping connection, and the application does not make specific limitation on the contact mode between the temperature sensing piece 140 and the ejector pipe 1310.

[0064] In some embodiments, referring toFigure 10 The heat transfer member 160 is connected with the ejector pipe 1310, and the temperature sensing member 140 is arranged on the heat transfer member 160. In this way, the temperature sensing member 140 can be in contact with the heat transfer member 160. When the stove 10 is in the combustion state, the temperature of the heat transfer member 160 is related to the temperature of the pot bottom. The temperature of the heat transfer member 160 is sensed by the temperature sensing member 140, so that the temperature of the pot bottom can be detected (i.e., the temperature of the pot is indirectly detected). The temperature sensing member 140 is not affected by the flame, which not only ensures the accuracy and rapidity of temperature detection, but also ensures that the temperature sensing member 140 does not interfere with the pot even when a pointed-bottom pot is used, thereby expanding the application range of the stove 10 and effectively improving the practicality of the stove 10.

[0065] For a single-ring burner head, the number of ejector pipes 1310 is only one, and the heat transfer member 160 can be connected with the single ejector pipe 1310. For a double-ring burner head, the heat transfer member 160 can be connected with the inner ring ejector pipe 1311, or the heat transfer member 160 can be connected with the outer ring ejector pipe 1312, or the heat transfer member 160 can be connected with both the inner ring ejector pipe 1311 and the outer ring ejector pipe 1312. For a three-ring burner head, the heat transfer member 160 can be connected with at least one of the inner ring ejector pipe 1311, the middle ring ejector pipe, or the outer ring ejector pipe 1312. For reference, Figure 10 The heat transfer member 160 can be arranged on the inner ring ejector pipe 1311. It should be understood that when the pot is placed on the burner head 130, the central region of the pot bottom is usually the part where heat is concentrated. When the number of ejector pipes 1310 is two or more, the inner ring ejector pipe 1311 is closer to the center of the burner head 130, and the temperature of the inner ring ejector pipe 1311 better reflects the temperature of the pot bottom. Therefore, connecting the heat transfer member 160 with the inner ring ejector pipe 1311 can make the heat transfer member 160 more accurately reflect the temperature of the pot bottom. In an embodiment not shown, the heat transfer member 160 can also be arranged on the ejector pipe 1310 other than the inner ring ejector pipe 1311.

[0066] Specifically, referring to Figure 11 The heat transfer member 160 can have a sleeving portion 1610, and the ejector pipe 1310 can have a matching segment 1313. The sleeving portion 1610 can be provided with a through hole (not shown in the figure). The sleeving portion 1610 can be sleeved on the matching segment 1313 through the through hole. In order to ensure the stability of the connection, the sleeving portion 1610 can also be connected with the matching segment 1313 by means of adhesion, welding, buckling, or the like. In this way, the heat transfer member 160 is convenient to install. In the case of heating with the pot placed on the burner head 130, the temperature of the pot bottom above the burner head 130 is transmitted to the sleeving portion 1610 through the ejector pipe 1310, so that the temperature of the heat transfer member 160 is related to the temperature of the pot bottom, thereby ensuring the accuracy and rapidity of temperature detection.

[0067] Further, referring toFigure 11 The outer edge of the sleeving part 1610 can extend out a plate-shaped part 1611. The plate-shaped part 1611 can have a to-be-measured surface 1612. The temperature sensing piece 140 can be attached to the to-be-measured surface 1612. In this way, the temperature sensing piece 140 is conveniently installed, and in the case of heating with a pot, the temperature of the bottom of the pot above the burner 130 is transmitted to the plate-shaped part 1611 through the ejector pipe 1310, so that the temperature of the plate-shaped part 1611 is related to the temperature of the bottom of the pot, ensuring the accuracy and rapidity of temperature detection.

[0068] It should be understood that in the embodiments of the present application, the temperature sensing piece 140 actually indirectly detects the temperature of the bottom of the pot by detecting the temperature of the heat transfer piece 160. In order to ensure the accuracy of temperature detection, the heat transfer piece 160 can be made of a heat-conducting material, such as metal or other materials with good heat transfer performance. Specifically, the heat transfer piece 160 and the ejector pipe 1310 can be made of the same material, such as stainless steel, so that the heat transfer piece 160 and the ejector pipe 1310 form a stainless steel assembly.

[0069] In some embodiments, referring to Figure 10 At least part of the temperature sensing piece 140 forms a surface contact with the heat transfer piece 160. In this way, the temperature sensing piece 140 can directly form a surface contact with the heat transfer piece 160, which not only ensures that the sensing piece can sense the temperature of the heat transfer piece 160, but also simplifies the connection between the sensing piece and the heat transfer piece 160. When the temperature sensing piece 140 needs to be repaired or replaced, the temperature sensing piece 140 can be conveniently disassembled, effectively improving the convenience of use for the operator.

[0070] Specifically, the heat-conducting part 1410 of the temperature sensing piece 140 can be plate-shaped, and the plate-shaped heat-conducting part 1410 can be attached to the heat transfer piece 160 to achieve the surface contact between the two.

[0071] Further, the temperature sensing piece 140 and the heat transfer piece 160 can be connected by welding, riveting, pasting or buckling, etc., which is not limited in the present application.

[0072] In some embodiments, in combination with reference to Figure 2 and Figure 3 The projection of the support 1320 towards the plane where the cavity bottom wall 1111 is located is located in the first area 1112. In this way, the support 1320 can be arranged close to the heat dissipation hole 150, and the heat transferred to the support 1320 and the heat generated by the components on the support 1320 can be quickly dissipated through the heat dissipation hole 150, avoiding the accumulation of heat in the installation cavity 1110, effectively improving the safety and reliability of the stove 10.

[0073] In some embodiments, referring to Figure 2The heat dissipation hole 150 is a circular hole, and the sensing surface 1411 of the temperature sensing element 140 is projected onto the plane of the cavity bottom wall 1111 and located in the circular hole. In this way, the sensing surface 1411 of the temperature sensing element 140 can be located directly above the heat dissipation hole 150, and the heat generated by the temperature sensing element 140 can be first discharged through the heat dissipation hole 150, so that the temperature sensing element 140 can always be in a stable and suitable working environment temperature, effectively improving the sensing accuracy and service life of the temperature sensing element 140, and further improving the safety and reliability of the stove 10.
