C The previous 3 conventional technologies are based on Japanese Patent Laid-Open Publication No. 11-201461. This conventional pot bottom temperature sensor includes: an inner tube, which is blocked by the heat collecting plate abutting the bottom surface of the conditioning 10 container to block the upper end. And an outer tube, which surrounds the inner tube, and a temperature detecting element is installed under the heat collecting plate, and at the same time, an upper end of the outer tube is provided with a projecting radially inward to form a substantially closed space between the inner tube and the outer tube. Covered by. According to this, through the heat insulation effect of the space between the inner cylinder and the outer cylinder, the thermal influence of the heat source from the 15 stoves on the temperature detecting element is eliminated, and the temperature detecting element can correctly detect the temperature of the conditioning container through the heat collecting plate. Here, if the lid portion is in contact with the inner tube, the heat from the cylinder exposed to the heat from the heat source is transmitted to the heat collecting plate via the lid portion and the inner tube to increase the detection temperature. Therefore, the lid portion is made not to contact the inner tube, so that There is a slight 20 clearance between the lid and the inner tube, so there may be cases where the overflowing soup flows into the outer tube through the clearance. Problem to be Solved by the Invention In view of this, an object of the present invention is to provide a pot bottom temperature sensor for a stove that can prevent the soup from overflowing from the gap. 200402522 C Summary of the invention; j Means of solving the problem In order to solve the foregoing problem, the present invention provides _ a kind of boiler bottom temperature sensor for stoves, including: an inner cylinder, which is contacted by the 5 heat collecting plates on the bottom surface of the conditioning container Those who block the upper end; and the outer tube, which surrounds the inner tube, and a temperature detecting element is installed under the heat collecting plate, and a cover portion protruding radially inward is provided at the upper end of the outer tube, and the cover portion is not The inner tube is in contact with a gap between the cover portion and the inner tube, and an umbrella portion is formed outside the heat collecting plate to cover the gap from above and protrude above the cover portion without touching the cover portion. 10 According to the foregoing structure, the umbrella portion covering the gap can prevent the overflowing soup from flowing from the gap between the lid portion and the inner tube. At this time, if the portion where the umbrella portion and the lid portion are heavy with each other forms an inclined portion sloping downward in the radial direction outward, the overflowing soup can also be prevented from flowing from the lid portion and the inner tube along the gap between the umbrella portion and the lid portion. The interstitial space flows in. 15 In addition, since the umbrella portion does not contact the lid portion, the heat of the outer cylinder is not transmitted to the heat collecting plate through the lid portion and the umbrella portion, and the temperature of the conditioning container can be accurately detected by the temperature detecting element through the heat collecting plate. . In addition, in the present invention, even if the gap between the cover portion and the inner tube is large, the space between the inner tube and the outer tube can be substantially closed by reducing the gap between the cover portion and the umbrella portion to ensure heat insulation, because 20 This can also leave a large gap between the lid and the inner tube.

The gas burner 3 is disposed below the glass top plate 1 and is composed of an inner flame burner having a plurality of flame holes 3b facing the burner head 3a. The burner head 3a is connected to the furnace. Those with openings 2 have concentric rings. The gas burner 3 is provided with a flame detecting thermocouple 3c or an ignition electrode (not shown), and a burner cover 5 is provided above the burner head 3a. A protective member 2a for preventing cracking is attached to the opening edge of the stove opening 2. Below the space surrounded by the burner head 3a, a ring-shaped soup receiving tray 6 for receiving the overflowing soup falling from the opening 10 of the stove 2 is arranged. In addition, a support tube 7 fixed to the stove body is erected in the inner peripheral space of the soup receiving tray 6, and the bottom tube temperature sensor 8 is supported by the support tube 7. In addition, a heat-receiving tube 9 is formed on the soup receiving plate 6 to surround the bottom temperature sensor 8, and the flame or heat of the gas burner 3 does not reach the bottom temperature sensor 8. 15 The pot bottom temperature sensor 8 is provided with a temperature detecting element 80 ′ such as a thermistor, and the temperature detecting element 80 is installed below the heat collecting plate 81 which abuts the bottom surface of the conditioning container p, and is configured to pass through the heat collecting plate. 81, and the temperature of the conditioning container p is detected by the temperature detecting element 80. In addition, in order to eliminate the influence of the radiant heat from the heat insulation tube 9 on the temperature detecting element 8020, 5 the inner tube 82 at the upper end and the outer tube 83 surrounding the inner tube 82 are blocked by the heat collecting plate 81. The inner tube 82 and the outer tube 83 are fixed and fixed to each other under the lower ends. In addition, the inner cylinder 82 is embedded with a freely sliding spring bearing 7a mounted on the upper end of the support tube 7, and a spring 84 is provided between the spring bearing% and the heat collecting plate 81, and is supported by the spring 84. The pipe 7 imparts upward potential energy to 200402522 to support the bottom temperature salt reactor 8.
