Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of the range, specifically, a temperature sensing piece, a burner, a combustor and 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 existing gas range is usually provided with a temperature sensing probe to detect the temperature of the pot, and to judge whether the combustor is dry burning, accidental extinguishing or the like according to the detected temperature, so that the gas source can be cut off in the first time when the above-mentioned situations occur, to avoid safety hazards.

[0003] At present, most of the gas ranges on the market are provided with an infrared temperature detection device beside the fire cover, which senses the temperature of the bottom of the pot, and automatically extinguishes the flame when the temperature of the bottom of the pot exceeds the preset temperature; at the same time, when the range accidentally extinguishes the flame and the pot is not placed on the range for a long time, the gas source can also be cut off in the first time based on the detection result of the infrared temperature detection device to avoid accidents.

[0004] However, the infrared temperature detection device is easily disturbed by the external environment (such as temperature, humidity, water vapor or smoke, etc.) during use, resulting in inaccurate temperature detection result, and thus reducing the safety and reliability of the range. SUMMARY

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

[0006] The temperature sensing piece comprises a heat-conducting part, a sensing part and a signal transmission line, the heat-conducting part has a contact plane in contact with a temperature-measured piece, the sensing part is connected with the heat-conducting part, and the sensing part obtains temperature information of the temperature-measured piece through the contact plane, and the signal transmission line is connected with the sensing part to transmit the temperature information outward.

[0007] The temperature sensing piece of the utility model can contact the temperature-measured piece through the contact plane on the heat-conducting part, so that the surface heat of the temperature-measured piece can be transmitted to the sensing part, the sensing part can convert the heat into specific temperature information, and transmit the temperature information to the outside through the signal transmission line, so that the temperature detection and monitoring of the temperature-measured piece are realized. Through the direct contact between the temperature sensing piece and the temperature-measured piece, the interference of the external use environment on the temperature sensing piece can be avoided, and the accuracy of the temperature measurement result of the temperature sensing piece is effectively ensured. When the temperature sensing piece is applied to the range, the temperature of the bracket of the burner can be detected to indirectly detect the temperature of the bottom of the pot, the temperature sensing piece is not affected by the flame, the safety and reliability of the range are improved, and even in the case of using a sharp-bottomed pot, the temperature sensing piece will not interfere with the pot, so the application range of the range is expanded.

[0008] Exemplarily, the sensing part comprises a body and a sensing chip, the sensing chip is arranged in the body, and one end of the signal transmission line is connected with the sensing chip. In this way, the sensing chip can be arranged in the body, so as to effectively protect the sensing chip from the external environment such as dust, water vapor or mechanical impact, greatly improving the service life and reliability of the sensing chip. Moreover, the direct connection of the sensing chip and the signal transmission line greatly reduces the delay of signal transmission, so that the temperature sensing chip can quickly respond to temperature changes and transmit temperature information outward.

[0009] Exemplarily, the heat conduction part is configured in a sheet structure. In this way, the sheet structure of the heat conduction part not only can reduce the volume of the heat conduction part and reduce the overall weight of the temperature sensing piece, but also can have a larger contact area with the surface of the temperature to be measured, effectively ensuring the heat transfer and improving the heat conduction efficiency of the heat conduction part.

[0010] Exemplarily, the heat conduction part has a thickness D, and the thickness D is 0.4mm-1mm. In this way, the heat conduction part with the above thickness range can not only ensure efficient heat transfer, but also reduce the volume and weight of the heat conduction part, effectively improving the practicality and flexibility of the temperature sensing piece.

[0012] Exemplarily, the heat conduction part has a length L1, and the length L1 is 5mm-15mm. In this way, the heat conduction part with the above length range can effectively ensure that the heat generated by the temperature to be measured is efficiently and accurately transferred to the sensing part through the heat conduction part, avoiding the situation that the sensing result of the sensing part is inaccurate due to the length of the heat conduction part being too long or too short, and effectively improving the reliability and accuracy of the temperature sensing piece.

[0013] Exemplarily, the heat conduction part has a width M, and the width M is 3mm-10mm. In this way, the heat conduction part with the above width range can effectively ensure that the heat generated by the temperature to be measured is efficiently and accurately transferred to the sensing part through the heat conduction part, avoiding the situation that the sensing result of the sensing part is inaccurate due to the width of the heat conduction part being too large or too small, and further improving the reliability and accuracy of the temperature sensing piece.

[0014] Exemplarily, the sensing part has a length L2, the sensing chip and the end of the body away from the heat conduction part have a length L3, L1:L2=1:3-1:1, and L3:L2=1:3-1:1.

[0015] Exemplarily, the heat-conducting part has an alloy material layer and an electroplated layer, the electroplated layer is formed on the surface of the alloy material layer, and the outer surface of the electroplated layer away from the alloy material layer forms a contact plane. In this way, the heat-conducting part can be composed of the alloy material layer and the electroplated layer, and the contact plane can be formed on the electroplated layer, so as to not only simplify the structure of the heat-conducting part, but also significantly improve the corrosion resistance, wear resistance and heat-conducting performance of the heat-conducting part. The electroplated layer can also avoid rusting of the sheet part, thereby improving the service life of the temperature sensing element.

[0016] Exemplarily, the contact plane has an area S1, and the area S1 is 60mm 2 ~ 80mm 2 In this way, the contact plane with the above area can ensure that the contact plane and the temperature measuring element can be in sufficient contact, thereby ensuring that heat can be quickly and efficiently transmitted from the temperature measuring element to the sensing part through the heat-conducting part. In addition, the close contact between the contact plane and the temperature measuring element can significantly reduce the contact thermal resistance, thereby improving the heat-conducting efficiency of the heat-conducting part.

[0017] Exemplarily, the heat-conducting part is provided with a connecting hole for the fastener to pass through, and the connecting hole has an area S2, and S2:S1=1:5~1:2. In this way, the ratio between the area of the connecting hole and the area of the contact plane of the heat-conducting part can be 0.2 to 0.5, so as to not only ensure that the temperature sensing element and the temperature measuring element are closely connected, but also avoid the situation that the heat-conducting effect of the heat-conducting part is poor due to the area of the connecting hole being too large.

[0020] Exemplarily, the temperature sensing piece is detachably connected with the support through the clamping structure. In this way, the temperature sensing piece and the support can be respectively provided with the clamping structures matched with each other, and the two are firmly connected through the clamping structures, and the connection between the two does not require other accessories, which greatly reduces the cost of materials and assembly while ensuring the convenient disassembly of the temperature sensing piece.

DETAILED DESCRIPTION

[0037] 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.

[0038] In order to thoroughly understand the embodiments of the present application, detailed structures will be presented in the following description. It is obvious that 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 have other embodiments.

[0039] In one embodiment of the utility model, a temperature sensing piece 10 is provided, which can avoid the interference of external use environment on the temperature sensing piece 10, and effectively ensure the accuracy of the temperature measurement result of the temperature sensing piece 10. In the following, a temperature sensing piece 10 according to the embodiment of the utility model will be introduced in detail in combination with the drawings.

[0040] In combination with the drawings, Figure 1 , Figure 2 and Figure 3 , the temperature sensing piece 10 comprises a heat conduction part 110, a sensing part 120 and a signal transmission line 130, the heat conduction part 110 has a contact plane 1101 in contact with a temperature measuring object, the sensing part 120 is connected with the heat conduction part 110, and the sensing part 120 obtains temperature information of the temperature measuring object through the contact plane 1101, and the signal transmission line 130 is connected with the sensing part 120 to transmit the temperature information outward.

[0041] The temperature sensing piece 10 of the utility model, the contact plane 1101 on the heat conduction part 110 can be in contact with the temperature measuring object, so that the surface heat of the temperature measuring object can be transmitted to the sensing part 120, and the sensing part 120 can convert the heat into specific temperature information and transmit it to the outside world through the signal transmission line 130, so that the temperature detection and monitoring of the temperature measuring object are realized. Through the direct contact of the temperature sensing piece 10 with the temperature measuring object, the interference of the external use environment on the temperature sensing piece 10 can be avoided, and the accuracy of the temperature measurement result of the temperature sensing piece 10 is effectively ensured. When the temperature sensing piece 10 is applied to the stove 50, the temperature of the support 320 of the burner 30 can be detected to indirectly detect the temperature of the bottom of the pot, so that the temperature sensing piece 10 is not affected by the flame, the safety and reliability of the use of the stove 50 are improved, and even in the case of using a pointed bottom pot, the temperature sensing piece 10 will not interfere with the pot, and the application range of the stove 50 is expanded.

[0042] Specifically, the two ends of the sensing part 120 can be connected with the heat conduction part 110 and the signal transmission line 130 respectively, the heat conduction part 110 can be used to transmit the heat on the surface of the temperature measuring object, the sensing part 120 can convert the perceived heat into temperature information, and the signal transmission line 130 can transmit the temperature information to an external device. Through the above split type design, the structure and layout of the temperature sensing piece 10 can be more stable, and the risk of failure caused by complex structure is reduced.

[0043] Further, the heat conduction part 110 can be in the shape of a plate, the plate-shaped heat conduction part 110 can have a contact plane 1101 with the temperature measuring object, and through the close fit of the contact plane 1101 with the surface of the temperature measuring object, the heat of the temperature measuring object can be quickly and efficiently transmitted to the sensing part 120, so that the loss and delay in the heat transmission process are greatly reduced, and the sensing part 120 can obtain more accurate temperature information.

[0044] Further, the heat-conducting part 110 can be made of copper or aluminum or other materials with good heat conductivity. The application does not make specific limitations on the material of the heat-conducting part 110, and any material with good heat conductivity can be used.

[0045] Of course, the shape of the heat-conducting part 110 can be determined according to the shape and size of the temperature-sensing part to meet different use scenarios and use requirements. For example, the shape of the heat-conducting part 110 can be circular, square, irregular, or the like. The application does not make specific limitations on the shape of the heat-conducting part 110.

[0046] The above-mentioned signal transmission line 130 can transmit the temperature information obtained by the sensing part 120 to an external control system. During transmission, the signal transmission line 130 can effectively reduce the influence of electromagnetic interference, dust, humidity, and other factors on the signal, thereby improving the reliability of the temperature-sensing part 10 and the accuracy of the temperature detection result.

[0047] In some embodiments, referring to Figure 4 The sensing part 120 includes a body 1201 and a sensing chip 1202, the sensing chip 1202 is arranged in the body 1201, and one end of the signal transmission line 130 is connected with the sensing chip 1202. In this way, the sensing chip 1202 can be arranged in the body 1201 to effectively protect the sensing chip 1202 from the influence of external environment such as dust, water vapor, or mechanical impact, greatly improving the service life and reliability of the sensing chip 1202. Moreover, the direct connection of the sensing chip 1202 with the signal transmission line 130 greatly reduces the delay of signal transmission, so that the temperature-sensing chip can quickly respond to temperature changes and transmit temperature information outward.

[0048] Specifically, the sensing chip 1202 can quickly respond to temperature changes and convert them into electrical signals. Moreover, through the efficient heat transfer of the heat-conducting part 110, the sensing chip 1202 can more accurately capture the slight changes in temperature.

[0049] Specifically, the sensing chip 1202 can be arranged in the body 1201 to avoid interference or influence of external environment such as high temperature or water vapor on the sensing chip 1202. The body 1201 and the sensing chip 1202 can be filled with a heat-conducting material, such as heat-conducting resin. In this way, the air between the sensing chip 1202 and the body 1201 can be excluded, reducing the contact thermal resistance and thereby improving the efficiency of heat transfer to the sensing chip 1202.

[0050] Further, the shape of the sensing chip 1202 can be spherical or square, etc. to increase the contact area between the sensing chip 1202 and the heat-conducting material, thereby further improving the efficiency of heat transfer to the sensing chip 1202. The application does not make specific limitations on the shape of the sensing chip 1202.

[0051] Further, the body 1201 has an inclined surface 1201a inclined to the contact surface 1101 of the heat conduction part 110, and the inclined surface 1201a forms an angle a with the contact surface 1101, and the angle a is in a range of 30 degrees to 60 degrees (°), for example, 30°, 40°, 45°, 50°, 60°, etc., and preferably 45°.

[0052] In some embodiments, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the heat conduction part 110 is configured as a sheet structure. In this way, the sheet structure of the heat conduction part 110 not only reduces the volume of the heat conduction part 110 and reduces the overall weight of the temperature sensing part 10, but also has a larger contact area with the surface of the temperature sensing part, effectively ensuring the transfer of heat and improving the heat conduction efficiency of the heat conduction part 110.

[0053] In some embodiments, referring to Figure 4 , the heat conduction part 110 has a thickness D of 0.4mm-1mm. In this way, the heat conduction part 110 with the above thickness range can not only ensure efficient heat transfer, but also reduce the volume and weight of the heat conduction part 110, effectively improving the practicality and flexibility of the temperature sensing part 10.

[0054] Specifically, the thickness D is in a range of 0.4mm to 1mm, for example, 0.4mm, 0.6mm, 0.8mm, 1mm, etc., and preferably 0.6mm.

[0055] The heat conduction part 110 with the above thickness can quickly transfer heat from the contact surface 1101 to the sensing part 120, reducing the residence time of heat in the heat conduction part 110, thereby improving the heat conduction speed of the entire temperature sensing part 10. Moreover, the heat conduction part 110 with the above thickness has a lower thermal resistance, which can more efficiently transfer heat, thereby improving the accuracy of the temperature information obtained by the sensing part 120.

[0056] The heat conduction part 110 with the above thickness can make the temperature sensing part 10 suitable for use in space-limited devices or systems, such as small electronic devices or high-density integrated devices, effectively improving the practicality of the temperature sensing part 10.

[0057] In some embodiments, referring to Figure 4 , Figure 4 , Figure 1 and Figure 2The heat-conducting part 110 is in a strip shape. In this way, the heat-conducting part 110 in the strip shape can quickly transfer heat from the temperature-measuring object to the temperature-sensing chip, effectively reducing the accumulation of heat in the heat-conducting part 110, thereby improving the heat-conducting efficiency of the heat-conducting part 110.

[0058] Of course, the heat-conducting part 110 can be adapted to the shape of the outer surface of the temperature-measuring object to ensure that the contact plane 1101 of the heat-conducting part 110 can be closely attached to the outer surface of the temperature-measuring object, thereby ensuring accurate heat transfer.

[0059] In some embodiments, referring to Figure 3 The heat-conducting part 110 has a length L1 of 5-15 mm. In this way, the heat-conducting part 110 with the above length range can effectively ensure that the heat generated by the temperature-measuring object is efficiently and accurately transferred to the sensing part 120 through the heat-conducting part 110, avoiding the situation that the sensing part 120 senses inaccurate results due to the length of the heat-conducting part 110 being too long or too short, and effectively improving the reliability and accuracy of the temperature-sensing object 10.

[0060] Specifically, the length L1 is in the range of 5-15 mm, for example, 5 mm, 8 mm, 10 mm, 15 mm, etc., and is preferably 10 mm.

[0061] The length of the heat-conducting part 110 should not be too long or too short. When the length of the heat-conducting part 110 is too long, heat loss may occur during heat transfer. When the length of the heat-conducting part 110 is too short, it may result in less heat transferred by the heat-conducting part 110, thereby affecting the accuracy of the temperature information obtained by the sensing part 120.

[0062] In some embodiments, referring to Figure 4 The heat-conducting part 110 has a width M of 3-10 mm. In this way, the heat-conducting part 110 with the above width range can effectively ensure that the heat generated by the temperature-measuring object is efficiently and accurately transferred to the sensing part 120 through the heat-conducting part 110, avoiding the situation that the sensing part 120 senses inaccurate results due to the width of the heat-conducting part 110 being too large or too small, and further improving the reliability and accuracy of the temperature-sensing object 10.

[0063] Specifically, the width M is in the range of 3-10 mm, for example, 3 mm, 6 mm, 8 mm, 10 mm, etc., and is preferably 6 mm.

[0064] The width of the heat conduction part 110 should not be too long or too short. When the width of the heat conduction part 110 is too large, heat loss may occur during heat transfer. When the width of the heat conduction part 110 is too small, the heat transferred by the heat conduction part 110 per unit time may be reduced, resulting in slow heat conduction of the heat conduction part 110, thereby affecting the accuracy of the temperature information obtained by the sensing part 120.

[0065] In some embodiments, referring to Figure 4 The sensing part 120 has a length L2, and the length between the sensing chip 1202 and the end of the body 1201 away from the heat conduction part 110 is L3, L1: L2 = 1:3-1:1, and L3: L2 = 1:3-1:1. In this way, the sensing temperature device 10 has a suitable length ratio between the components, which not only ensures that the sensing temperature device 10 has good temperature sensing effect, but also improves the miniaturization and practicality of the sensing temperature device 10.

[0066] For example, the length L2 of the sensing part 120 is in the range of 10-30 millimeters (mm), for example, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, etc., and preferably 20 mm. The sensing part 120 with the above length range avoids the sensing temperature device 10 being too large due to the length of the sensing part 120 being too long, effectively ensuring the miniaturization design of the sensing temperature device 10.

[0067] For example, the length L3 between the sensing chip 1202 and the end of the body 1201 away from the heat conduction part 110 is in the range of 5-15 millimeters (mm), for example, 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, etc., and preferably 10 mm. In this way, the contact area between the sensing chip 1202 and the heat conduction material can be further ensured, thereby ensuring the accuracy and reliability of the detection results of the sensing chip 1202.

[0068] In some embodiments, the heat conduction part 110 has an alloy material layer and an electroplated layer, the electroplated layer is formed on the surface of the alloy material layer, and the outer surface of the electroplated layer away from the alloy material layer forms a contact plane 1101. In this way, the heat conduction part 110 can be composed of an alloy material layer and an electroplated layer, and the contact plane 1101 can be formed on the electroplated layer. In this way, not only is the structure of the heat conduction part 110 simplified, but also the corrosion resistance, wear resistance and heat conduction performance of the heat conduction part 110 are significantly improved. The electroplated layer can also avoid rusting of the flaky part, thereby improving the service life of the sensing temperature device 10.

[0069] The electroplating layer effectively isolates the alloy material layer from the external environment, preventing corrosion and significantly improving the corrosion resistance of the heat-conducting part 110. Furthermore, the electroplating layer possesses high hardness and wear resistance, resisting external friction and abrasion, effectively extending the service life of the heat-conducting part 110.

[0070] Specifically, the alloy material layer can be made of copper, and the electroplating layer can be made of nickel. This application does not specifically limit the material of the alloy material layer and the electroplating layer.

[0071] In some embodiments, the contact plane 1101 has an area S1, which is 60 mm². 2 ~80mm 2 Thus, the contact plane 1101 with the aforementioned area ensures sufficient contact between the contact plane 1101 and the element to be measured, thereby ensuring that heat can be quickly and efficiently transferred from the element to the sensing part 120 through the heat-conducting part 110. Furthermore, the close contact between the contact plane 1101 and the element to be measured significantly reduces the contact thermal resistance, thereby improving the thermal conductivity of the heat-conducting part 110.

[0072] Specifically, the area S1 ranges from 60 square millimeters to 80 square millimeters (mm). 2 For example, 60mm 2 65mm 2 68mm 2 75mm 2 80mm 2 Etc., preferably 68mm 2 .

[0073] In some embodiments, in conjunction with reference Figure 4 and Figure 4 The heat-conducting part 110 is provided with a connecting hole 1102 for the fastener 20 to pass through. The connecting hole 1102 has an area S2, where S2:S1 = 1:5 to 1:2. Thus, the ratio between the area of ​​the connecting hole 1102 and the area of ​​the contact plane 1101 of the heat-conducting part 110 can be between 0.2 and 0.5. This not only ensures a tight connection between the temperature sensing element 10 and the element to be measured, but also avoids the situation where the heat-conducting part 110 has poor heat conduction due to the area of ​​the connecting hole 1102 being too large.

[0074] Specifically, the heat-conducting part 110 can be provided with a connecting hole 1102, and the fastener 20 can be connected to the temperature-measuring object through the connecting hole 1102. The fastener 20 can be a bolt or a screw. The diameter of the fastener 20 can be 3-6 mm, for example, 3 mm, 4 mm, 5 mm, 6 mm, and preferably 4 mm. The length of the fastener 20 can be 4-8 mm, for example, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, and preferably 6 mm.

[0075] In an embodiment not shown, a heat-insulating material can be arranged between the fastener 20 and the heat-conducting part 110 to minimize the influence of the fastener 20 on the heat-conducting part 110 when heat is conducted by the heat-conducting part 110.

[0076] According to another aspect of the present application, in combination with the Figure 1 and Figure 2 A furnace head 30 is also provided, which comprises an ejector pipe 310, a support 320, and the temperature-sensing object 10 as described above.
