For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Reference below Figure 1-Figure 4 A temperature detector 100 according to an embodiment of the present invention is described.

[0041] like Figure 1 As shown, the temperature detector 100 according to the first embodiment of the present invention includes: an insulating column 10, a first electrode (not shown in the figure), a second electrode (not shown in the figure), a first wire 20 and a second wire 21.

[0042] Among them, a rounded corner is constructed between the end face and the side surface of the insulating column 10, the first electrode is arranged on the side surface of the insulating column 10 and extends to the end face of the insulating column 10, the second electrode is arranged on the side surface of the insulating column 10 and extends to the end face of the insulating column 10, the first electrode and the second electrode form a temperature detection area 13 in the overlapping area of ​​the end face of the insulating column 10, the first wire 20 is connected to the first electrode, and the second wire 21 is connected to the second electrode.

[0043] Specifically, if Figure 1As shown, the insulating column 10 can be a column made of insulating material, or a column made of non-insulating material with an insulating layer, that is, the contact surfaces of the first electrode and the second electrode with the insulating column 10 are both insulated, and a fillet is constructed between the side surface and the end face of the insulating column 10, and the cross-sectional area of ​​the portion of the insulating column 10 forming the fillet gradually decreases in the direction toward the end face, thereby, the area of ​​the end face of the insulating column 10 is smaller.

[0044] The first electrode and the second electrode are made of nanometer-scale galvanic material, one of the first electrode and the second electrode is made of positive galvanic material, and the other of the first electrode and the second electrode is made of negative galvanic material. The first electrode extends from the end face of the insulating column 10 to the side surface of the insulating column, and the second electrode extends from the end face of the insulating column 10 to the side surface of the insulating column. It should be noted that the end face of the insulating column 10 refers to one of the two end faces of the insulating column 10, for example Figure 1 In the embodiment shown, the upper end surface of the insulating column 10, the first electrode and the second electrode have an overlapping area on the end surface of the insulating column 10. The temperature of the overlapping area generates different thermoelectric potentials for the positive electrode material and the negative electrode material. The temperature of the overlapping area can be obtained by measuring the thermoelectric potential. The temperature detection area 13 is suitable for directly contacting the bottom of the pot to detect the temperature of the bottom of the pot.

[0045] According to the temperature detector 100 of the embodiment of the present invention, a fillet is constructed between the end face and the side surface of the insulating column 10, and the cross-sectional area of ​​the fillet portion gradually decreases in the direction toward the end face of the insulating column 10. In this way, the area of ​​the end face of the insulating column 10 is smaller, and the area of ​​the temperature detection zone 13 formed by the first electrode and the second electrode on the end face is also correspondingly smaller. As a result, the contact area between the temperature detection zone 13 and the bottom of the cookware is smaller and the contact is closer. Even if the cookware is a pointed bottom pot or the bottom of the cookware is tilted, the bottom of the cookware can still be in good contact with the temperature detection zone 13, thereby reducing the gap between the bottom of the cookware and the temperature detection zone 13, making it less susceptible to the influence of hot air flow or external high temperature environment between the bottom of the cookware and the temperature detection zone 13, and the temperature detected by the temperature detection zone 13 is more accurate and the measurement result is more stable.

[0046] Furthermore, the temperature detector 1 in the related art needs to set a heat collection plate between the thermocouple and the bottom of the cookware. The thermocouple indirectly obtains the temperature of the bottom of the cookware by measuring the temperature of the heat collection plate. The temperature detector 100 of the embodiment of the present invention directly obtains the temperature of the bottom of the cookware by contacting the temperature detection area 13 set on the end face of the insulating column 10 with the bottom of the cookware. The temperature measurement is more timely and the measured data is more accurate.

[0047] Therefore, the temperature detector 100 according to the embodiment of the present invention has the advantages of good contact with the bottom of the cookware, stable temperature measurement results and accurate measurement data.

[0048] According to some embodiments of the present invention, Figure 1 As shown, the insulating column 10 is a cylinder. The insulator used in the temperature monitor in the related art is usually a rectangular parallelepiped. During production, the right-angled sides of the insulator are easily stretched, resulting in a low yield rate, thereby affecting the overall performance. In the embodiment of the present invention, the insulating column 10 adopts a cylindrical structure, thereby improving the yield rate of the insulating column 10, thereby making the structure of the temperature detector more stable and the measurement result more accurate.

[0049] According to some embodiments of the present invention, Figure 1 As shown, the side surface of the insulating column 10 is provided with a first wire groove 11 and a second wire groove 12, the first electrode is provided in the first wire groove 11 and extends to the end surface of the insulating column 10, and the second electrode is provided in the second wire groove 12 and extends to the end surface of the insulating column 10. Thus, it is convenient to provide the first electrode and the second electrode on the side surface of the insulating column 10, and the first electrode located in the first wire groove 11 and the second electrode located in the second wire groove 12 can be well isolated, and the electrode material will not touch the outside world to cause the electrode material to fall off, so the first electrode and the second electrode can be well protected.

[0050] According to some embodiments of the present invention, continue to refer to Figure 1 In the embodiment shown, the first wire groove 11 and the second wire groove 12 extend along the axial direction of the insulating column 10. That is, the first wire groove 11 and the second wire groove 12 are respectively arranged parallel to the central axis of the insulating column 10, so that the first wire groove 11 and the second wire groove 12 are parallel to each other, and the length of the first wire groove 11 and the second wire groove 12 on the insulating column 10 is relatively short, which is convenient for processing and is conducive to the arrangement of the first wire 20 and the second wire 21.

[0051] Optionally, in the cross section of the insulating column 10, the line between the first wire groove 11 and the second wire groove 12 passes through the center of the insulating column 10. It is worth noting that the line between the first wire groove 11 and the second wire groove 12 refers to the shortest straight line connecting the first wire groove 11 and the second wire groove 12, and the line passes through the center of the insulating column 10, so that the first wire groove 11 and the second wire groove 12 are symmetrical about the central axis of the insulating column 10, and the distance between the first wire groove 11 and the second wire groove 12 in the circumferential direction of the insulating column 10 is the largest, which is convenient for arranging the first electrode and the second electrode in the first wire groove 11 and the second wire groove 12 respectively, and the isolation effect of the first electrode in the first wire groove 11 and the second electrode in the second wire groove 12 is good, and the temperature measurement is more accurate.

[0052] In some embodiments of the present invention, the first wire 20 and the first wire slot 11 as well as the second wire 21 and the second wire slot 12 are connected by welding, conductive adhesive bonding or metal melting point bonding.

[0053] Specifically, the first wire 20 and the second wire 21 can be connected to the first wire groove 11 and the second wire groove 12 respectively by welding, so as to connect the first wire 20 and the second wire 21 to the first electrode and the second electrode respectively; or, the first wire 20 and the second wire 21 can be adhered to the first wire groove 11 and the second wire groove 12 respectively by conductive glue, thereby, the first wire 20 and the second wire 21 can be electrically connected to the first electrode and the second electrode while being connected to the first wire groove 11 and the second wire groove 12 respectively; or, by applying melted conductive silver paste to the first wire groove 11 and the second wire groove 12, the first wire 20 and the second wire 21 are electrically connected to the first electrode and the second electrode respectively by point connection with the conductive silver paste.

[0054] Preferably, the first wire 20 and the second wire 21 as well as the first electrode and the second electrode are melted by a high energy beam (laser beam, electron beam, etc.), and after cooling, the first wire 20 and the first electrode are integrated, and the second wire 21 and the second electrode are integrated to achieve electrical connection between the wire and the electrode. Thus, the electrical connection between the wire and the electrode is better, and the integrated structure is not easy to separate.

[0055] In some embodiments of the present invention, Figure 2 As shown, the side surface of the insulating column 10 is provided with a plurality of grooves, each of which extends along the circumference of the insulating column 10 and is spaced apart along the axial direction of the insulating column 10, each of which is respectively connected to the first wire groove 11 and the second wire groove 12 and is provided with a clamp for clamping the first wire 20 and the second wire 21.

[0056] Specifically, a plurality of grooves are arranged at intervals along the axial direction of the insulating column 10, and each groove extends along the circumferential direction of the insulating column 10, the grooves are connected to both the first wire groove 11 and the second wire groove 12, the first wire 20 located in the first wire groove 11 passes through a plurality of grooves, and the second wire 21 located in the second wire groove 12 passes through a plurality of grooves, and a clamp is provided in each groove, which is clamped on the inner surface of the groove and presses the first wire 20 and the second wire 21 passing through the groove into the groove, thereby restraining and fixing the wires, and the connection effect between the wires and the insulating column 10 is further improved.

[0057] Optionally, continue to refer to Figure 2 In the embodiment shown, the groove is connected to the first wire groove 11 and the second wire groove 12 respectively, and the depth of the groove is equal to the depth of each of the first wire groove 11 and the second wire groove 12. That is, the groove intersects with the first wire groove 11 and the second wire groove 12 respectively, and the depth of the groove is equal to the depth of the first wire groove 11 and the depth of the second wire groove 12. Therefore, the first wire 20 and the second wire 21 are pressed by the clamp in the groove without bending, thereby playing a role in protecting the wires.

[0058] In some specific examples of the present invention, Figure 2 As shown, the plurality of grooves include a first groove 14 and a second groove 15 . The first groove 14 is closer to the temperature detection area 13 in the axial direction of the insulating column 10 than the second groove 15 . A first clamp 141 is disposed in the first groove 14 and a second clamp 151 is disposed in the second groove 15 .

[0059] Optionally, the first electrode extends from the end surface of the insulating column 10 to the first groove 14, and the second electrode extends from the end surface of the insulating column 10 to the second groove 15. In other words, the first electrode extends from the end surface of the insulating column 10 to the intersection of the first wire groove 11 and the first groove 14, and the second electrode extends from the end surface of the insulating column 10 to the intersection of the second wire groove 12 and the second groove 15.

[0060] Furthermore, if Figure 2 and Figure 3 As shown, the first clamp 141 and the second clamp 151 both have openings, the first wire 20 and the first electrode both pass through the opening of the second clamp 151 to be electrically separated from the second clamp 151, and the second wire 21 and the second electrode pass through the opening of the first clamp 141 to be electrically separated from the first clamp 141.

[0061] Specifically, the first clamp 141 and the second clamp 151 are both elastic parts, and the first clamp 141 and the second clamp 151 are both arc-shaped structures. The first clamp 141 and the second clamp 151 are respectively clamped in the first groove 14 and the second groove 15 through their respective openings. The first wire 20 and the first wire groove 11 avoid the second clamp 151 at the opening of the second clamp 151, and the second wire 21 and the second wire groove 12 avoid the first clamp 141 at the opening of the first clamp 141. Therefore, the first clamp 141 only contacts the first wire 20 and the first wire groove 11, and the second clamp 151 only contacts the second wire 21 and the second wire groove 12, thereby avoiding the situation where the first clamp 141 or the second clamp 151 simultaneously contacts the first electrode and the second electrode to cause a short circuit, thereby improving the stability of the temperature detector 100.

[0062] According to some embodiments of the present invention, the first electrode and the second electrode are both provided on the insulating column 10 by spraying. Specifically, the first electrode and the second electrode are formed by spraying nanoscale thermocouple materials on the insulating column 10, thereby, the first electrode and the second electrode are small in size and thin in thickness, the temperature detection area 13 formed by the first electrode and the second electrode can be in direct contact with the cookware, the timeliness and accuracy of temperature measurement are high, and the processing and manufacturing are convenient.

[0063] According to some embodiments of the present invention, the insulating column 10 is a ceramic component, that is, the insulating column 10 is made of a ceramic material, and thus, the insulating column 10 has the advantages of good insulation effect, high mechanical strength, good thermal stability, and the like.

[0064] In some embodiments of the present invention, Figure 4 As shown, the temperature detector 100 further includes a cover 30, which is sleeved on the outer side of the insulating column 10, and the cover 30 covers the first wire 20 and the second wire 21, and the temperature detection area 13 is exposed from the cover 30. Specifically, the cover 30 is covered on the outer surface of the insulating column 10 to isolate the side surface of the insulating column 10, the first electrode, the second electrode, the first wire 20 and the second wire 21 from the outside, so as to play a protective role, the end surface of the insulating column 10 with the temperature detection area 13 is exposed from the cover 30, the temperature detection area 13 is in direct contact with the bottom of the pot to detect the temperature of the bottom of the pot, and the first wire 20 and the second wire 21 extend from one end of the cover 30 away from the temperature detection area 13.

[0065] According to some optional examples of the present invention, Figure 4 As shown, the inner surface of the cover body 30 is provided with two matching protrusions 31 respectively matching with the first wire groove 11 and the second wire groove 12. Specifically, each matching protrusion 31 is formed by the side surface of the cover body 30 being recessed inwardly, and each matching protrusion 31 is consistent with the size of the corresponding wire groove. After the cover body 30 is assembled on the insulating column 10, the two matching protrusions 31 are correspondingly clamped in the first wire groove 11 and the second wire groove 12 one by one, so that the insulating column 10 can be prevented from rotating relative to the cover body 30 in the circumferential direction of the insulating column 10, so that the matching between the insulating column 10 and the cover body 30 is tighter and the overall consistency is better.

[0066] According to some embodiments of the present invention, an insulating glue is provided between the insulating column 10 and the cover 30. Specifically, the insulating glue is a high temperature resistant and insulating colloid, and the insulating glue is filled between the wire and the cover 30 and between the electrode and the cover 30 to prevent the wire or the electrode from contacting the cover 30 and causing a short circuit.

[0067] According to some embodiments of the present invention, a sealant is filled between the insulating column 10 and the cover 30. Specifically, the sealant is a high temperature resistant colloid, and the sealant is filled in the gap between the insulating column 10 and the cover 30, thereby the sealing performance between the insulating column 10 and the cover 30 is better, and the overall structural strength is further improved.

[0068] According to some embodiments of the present invention, the housing 30 has a lead end 32 for leading out the first wire 20 and the second wire 21. Specifically, the lead end 32 is located at the end face of the housing 30 away from the temperature detection area 13, and the lead end 32 is formed by an opening on the end face, and the first wire 20 and the second wire 21 extend out of the housing 30 from the lead end 32.

[0069] The cooking stove according to the second embodiment of the present invention includes the temperature detector 100 according to the first embodiment of the present invention.

[0070] The cooking stove according to the second embodiment of the present invention, by utilizing the temperature detector 100 according to the first embodiment of the present invention, has the advantages of stable temperature measurement results and accurate measurement data, which is conducive to achieving the advantages of preventing the pot from drying out and intelligent temperature control.
