INSTRUCTIONS: I: TECHNICAL FIELD OF THE INVENTION: FIELD OF THE INVENTION The present invention relates to a furnace bottom temperature sensor that abuts against the bottom surface of a conditioning container to detect the temperature of the container. BACKGROUND OF THE INVENTION In recent years, the temperature of a conditioning container placed on a gas-fired fire rack is detected by a pot bottom temperature detector, and a detection signal from the sensor is sent to a controller to control the burner of the furnace. The temperature of the container is maintained at the set temperature while preventing the scorching of the conditioning container. The steel bottom temperature sensor is provided with a thermal head having a built-in thermal circuit. The thermal head is supported by the upper end portion of the hollow support provided in the inner space of the burner surrounded by the annular burner by the potential energy given upward by the spring. A flat heat collecting plate is arranged at the front end of the thermal head, and a thermistor is mounted inside the heat collecting plate. A wire extending from the thermistor is pulled out from the lower end of the column by the inside of the column and connected to the controller (for example, refer to Patent Document 1). Further, 'the heat collecting plate is brought into contact with the bottom surface of the conditioning container heated by the furnace burner', and the thermistor is passed through the heat collecting plate to detect the temperature of the conditioning container. [PRIOR ART DOCUMENT] [Patent Document 1] Japanese Patent Application Laid-Open No. Hei 8-152135-A No. Hei No. Hei No. 8-152135. Further, in addition to the control of the burner for conditioning, control of the heat resistant temperature of the thermistor is also performed. That is, when the controller controls the temperature adjustment of the conditioning container, the heating temperature of the upper limit is set in consideration of the heat resistant temperature of the thermistor, and when the temperature is the upper limit heating temperature or the temperature thereof, the thermistor is protected. Fire control. However, depending on the conditioning material, even if the temperature of the conditioning container becomes extremely high, the heating of the conditioning material may be insufficient. In a specific example, when the rice cake is grilled at a high temperature such as a rice cake, the temperature of the thermal head that abuts the iron mesh rises in a relatively short period of time. Further, when the temperature rises to the upper limit heating temperature set by the heat resistant temperature of the thermistor, although the rice cake or the like is not fired, there is a case where the furnace is extinguished by the controller to extinguish the fire too early. Therefore, depending on the conditioning property, the thermal resistance is prematurely deteriorated, not only when the usability is deteriorated, but also when the temperature is raised to the upper limit heating temperature. Further, the wire of the thermal resistance resistor extends toward the inside of the pillar through the inside of the thermal head having the heat collecting plate abutting against the bottom surface of the conditioning container, but the periphery of the thermal head becomes relatively high as described above, and therefore, the coating is covered. The coated member of the wire is deteriorated by the influence of heat, and there is a possibility that the durability of the pan bottom temperature sensor is lowered. In view of the above, the present invention has been made in an effort to provide a pan bottom temperature sensor which is easy to use and has high durability. 201241370 [Means to solve the problem] d. In order to achieve such a purpose, the furnace bottom temperature sensing system of the present invention is applied upward from the inner space of the burner surrounded by the burner of the & burner and abuts the conditioning vessel heated by the furnace burner. The bottom surface, the levy: the temperature of the distiller's barn's special characteristics of the bottom temperature sensor of the furnace; 匕3 has a heat collecting plate that abuts the bottom surface of the conditioning container, and should be /, '', ' a bimetal which is deformed by the degree of the plate, and a deformation amount detecting mechanism for detecting the deformation amount of the bimetal and replacing the money with a value corresponding to the electrical value of the temperature. The flame hole of the burner flame is below. The pot bottom temperature sensor of the present invention can detect the container in the same manner as the thermistor by detecting the shape of the bimetal which is heated from the bottom surface of the column by the deformation amount detecting means. The temperature output is used as an electrical value' and can be easily controlled according to the temperature of the controller or the like. Moreover, the 'heated part' can be made of a bimetal having a high heat resistance temperature (for example, JIS standard TM4: heat-resistant temperature 500 ° C) compared with the conventional thermistor, and the upper limit of the high-temperature fire extinguishing according to the controller or the like can be used. The temperature is set to a higher temperature than the thermistor. Thereby, temperature control in a relatively high temperature range can be performed. For example, in the case of grilling rice cakes on an iron net, it is possible to avoid the fact that the rice cakes and the like have not been fired and are turned off prematurely, and the use convenience is good. Further, since the deformation amount detecting means is located below the flame hole of the furnace burner, the wire connected to the deformation amount detecting means for outputting the electrical value from the deformation amount detecting means may be combined with the deformation amount detecting means 201241370 They are placed together in a position away from the flame formed by the burner of the furnace. Thereby, the thermal influence on the deformation amount detecting mechanism and the wire can be reduced, and the durability of the deformation detecting mechanism or the wire can be improved. Further, in the present invention, either of the spiral bimetal and the bimetal of the flat plate shape (supported at both ends of the central portion of the movement or one end of the central portion) may be suitably employed. The spiral bimetal is deformed with its ends, and both ends rotate in opposite directions. Further, the deformation amount detecting means can effectively detect the temperature of the conditioning container by detecting the rotation angle of the bimetal. The flat bimetal is deformed with a part of it, and a part is displaced in the up and down direction. Further, the deformation amount detecting means can effectively detect the temperature of the conditioning container by detecting the displacement of the bimetal. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional view showing the description of an embodiment of the present invention. Fig. 2 is a cross-sectional view showing the description of another embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 3 BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings. Figure 1 shows the main part of the gas furnace. The gas burner is equipped with a furnace burner 1. The furnace burner 1 has an annular burner body 3 connected to the mixing pipe 2, and an annular burner head 4 on which the burner body 3 is placed. A plurality of flame holes 5 which are opened outward by a tooth shape are formed below the outer peripheral surface of the burner head 4. The burner body 3 is made of a metal plate and has an inner cylinder 6 and an outer cylinder 7. The inner cylinder 6 is provided with a cylindrical wall 8 of the burner head 4, and in the outer cylinder 7 6 201241370, a mounting portion 9 having a toothed shape of the burner head 4 is formed, and the mounting portion 9 is outwardly connected from the mounting portion 9. The outer peripheral wall portion 10 extends obliquely downward. Although not shown, a juice receiving tray for receiving the overflowing juice is provided on the outer periphery of the outer peripheral wall portion 10. Further, the flame frame 11 of the portion shown in Fig. 1 is provided on the outer side of the burner 1. Conditioning is carried out by placing a conditioning container (not shown) on the flame frame 11' and heating the conditioning container with the flame of the furnace burner 1. The furnace burner 1 is provided with a bottom temperature sensor that abuts against the bottom surface of the conditioning container heated by the burner 1, that is, the bottom surface of the conditioning container that is placed around the fire rack 11 of the burner 1 to detect the temperature thereof. 12. The bottom temperature sensor 12 is provided with a hollow tubular heat-sensitive portion 14 that is erected in a burner inner space 13 surrounding the cylindrical wall 8 of the furnace burner 1, and a hollow portion that is slidably movable in the vertical direction to maintain the heat-sensitive portion I4. Tubular support member 15. The heat sensitive portion 14 is provided with a heat collecting plate 16 that abuts against the bottom surface of the conditioning container, and a spiral bimetal 17 and a rotating potential leaf 18 (deformation amount detecting means) that extend in the vertical direction. The rotary potentiometer 18 is supported at the bottom of the heat sensing portion 14 below the flame hole 5 of the furnace burner 1. Thereby, the rotary potentiometer_wire 21 leaves the fire and is hardly affected by heat. The upper end of the bimetal 17 is integrally connected to the joint portion 19 of the heat collecting plate 16. The lower end of the bimetal 17 is integrally coupled to the input rotary shaft 20 of the rotary potentiometer °8. When the bimetal 17 is deformed by the heat transmitted from the heat collecting plate 16, the lower end is rotated by the snail 201241370. . At this time, the rotation is input to the input rotary shaft 20 of the rotary potentiometer 18. By using the spiral bimetal 17, the deformation amount (rotation amount) of the bimetal iridium can be effectively obtained without connecting the bimetal 17 and the member of the rotary potentiometer 18 to the input shaft 2 It is transmitted to the input rotary shaft 20. The rotary potentiometer 18 changes the resistance value of the electric electric current in response to the rotation angle of the input rotary shaft 2〇. The lead wire 21 extending from the rotary potentiometer 18 is connected to a controller (not shown). The resistance value obtained from the rotary potentiometer 18 corresponds to the deformation amount of the bimetal 17, and the deformation amount of the bimetal 17 corresponds to the temperature of the conditioning container received from the heat collecting plate 16 abutting on the bottom surface of the conditioning container. Therefore, in the controller, the furnace burner 控制 can be controlled in accordance with the resistance value obtained by the rotary potentiometer 18, and temperature control of the conditioning container becomes possible. The support member 15 is fixed by a bracket 23 attached to the support plate 22 for the furnace burner 1. An annular spring receiving portion 24 is formed at the lower end of the support member 15. A spring 25 is provided between the spring receiving portion 24 and the bottom of the heat sensing portion 14 so as to be pushed upward against the lower portion of the heat sensing portion 14. Thereby, when the conditioning container is placed on the fire frame 11, the heat sensitive portion 14 is pressed against the biasing force of the spring 25, and the heat collecting plate 16 is surely abutted against the bottom surface of the conditioning container by the compression reaction force of the spring 25. According to the above-described bottom temperature sensor 12, the heat of the heat collecting plate 16 is received by the bimetal 17, and the upper limit temperature at the time of forced fire extinguishing can be set to a relatively high temperature in the temperature control according to the controller. Specifically, when a conventional thermistor is used, it is considered that the heat resistance temperature of the heat resistor is about 350 °C, and the upper limit temperature of the fire extinguishing control must be about 320 °C, for example. On the other hand, as in the present embodiment, by using a bimetal having a heat-resistant temperature of 500 ° C (such as TM4 of JIS standard), the upper limit temperature of the fire extinguishing control can be made relatively high, for example, 450 ° C. Therefore, for example, in the case of grilling rice cakes on the iron net, it is possible to avoid the fact that the furnace burner 1 is extinguished by controlling the rice cake or the like without being fired, and the usability is good. The temperature sensor 26 will be described with reference to Fig. 2 . In addition, since the furnace burner 1 has the same configuration as that of the first embodiment, the description thereof will be omitted. ...the steel bottom temperature sensor % shown in Fig. 2 is provided with a hollow tubular heat-sensing member 28 which is disposed in the inner space 13 of the burner surrounded by the burner 27 and is slidable upward and downward. The support structure of the ground protection thief hot part 27 is provided with a bottom heat collecting plate 29, a flat metal, a double metal 3G, a linear potentiometer 31 (deformation amount detecting mechanism), and a ^ which are in contact with the conditioning container. The upper portion of the rod member 32 which is a rod-shaped rod member of the linear potentiometer 3 is connected to the inside of the heat collecting plate 29. The link member 32 is rotatably coupled to the lower half of the bimetal 3G. The link is constructed. The lower end is freely rockably coupled to the input pot of the linear potentiometer 31. When the flat 3G is deformed by the heat transmitted from the heat collecting plate 29, by being pre-shaped, the lower half thereof faces downward with respect to the upper half. Variable Bit. At this time, the displacement 201241370 is input to the wheel bar 33 of the linear potentiometer through the link member 32. The light potential blade is electrically connected to the resistance value of the input rod 33, and the wire % extending from the linear potentiometer 3 is connected to an electric limit value obtained from the linear potentiometer 31 (not shown) corresponding to the bimetal. The deformation of 30 == gold _ is the amount of deformation corresponding to the temperature of the conditioning container that is abutted from the bottom of the conditioning container. Therefore, in the controller, it is possible to control the temperature of the conditioning container in accordance with the resistance (four) __burner obtained from the potentiometer 31. Further, the linear potentiometer 31 is supported on the bottom side of the heat sensitive portion 27 and is located below the flame hole 5 of the furnace burner 1. Thereby, the linear potentiometer 31 and the wire 34 are separated from the flame and are hardly affected by heat. The support member 28 is fixed by a bracket 23 attached to the support plate 2 2 for use in the furnace burner. A ring-shaped elastic crest receiving portion 35 is formed at the lower end of the reading member ’. A spring 36 is provided between the spring receiving portion 35 and the bottom of the sensible rib to be pressed upward in response to the movement of the heat-sensitive portion 27. Thereby, when the conditioning container is placed on the fire frame 11, the heat sensitive portion 27 is pressed against the biasing force of the spring 26, and the plate 29 is reliably abutted against the conditioning container by the compression reaction force of the magazine 36. The bottom surface. The bottom temperature sensor 26 is also subjected to the heat of the heat collecting plate 29 by the bimetal 3〇 in the same manner as the above-described bottom temperature sensor 丨2, and can be forced by the temperature control of the controller. The upper limit temperature of the ground fire extinguishing is set to a higher temperature, and the use convenience is good. Further, in the bottom temperature sensor 26 shown in FIG. 2, although the bimetal 30 having a flat U-shape is used for the display of 10 201241370, although not shown, a flat plate may be used. The both ends support a bimetal having a shape in which the input rod 33 of the linear potentiometer 31 is moved up and down through the link member 32, such as a shape or a disk. Further, in each of the above-described embodiments, a potentiometer using a so-called rotary potentiometer 18 or a linear potentiometer 31 is used as the deformation amount detecting means of the present invention, but it is not limited thereto, as long as it is a bimetal. The deformation amount of 丨7, 30 can be converted into an electrical value (resistance value or signal). Specifically, in particular, regarding the rotation of the bimetal iridium shown in Fig. 1, a rotary encoder or the like can be used as the deformation amount detecting means, and the bimetal 30 shown in Fig. 2 can be displaced up and down. A linear encoder, a pressure sensor or a strain gauge is used as the deformation detecting mechanism.
