The conventional technique is based on Japanese Patent Laid-Open Publication No. 11-201461. This conventional pan bottom temperature sensor includes: an inner cylinder, which blocks the upper end by a heat collecting plate abutting the bottom surface of the conditioning container; and The outer tube is a person who surrounds the inner tube and installs a temperature detection element under the heat collecting plate, and at the same time, a cover portion protruding radially inward at the upper end of the outer tube to form a substantially closed space between the inner tube and the outer tube is provided. . 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 stove 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 cover portion is in contact with the inner tube, the heat from the tube exposed to the heat from the heat source is transmitted to the heat collecting plate via the cover portion and the inner tube to increase the detection temperature. Therefore, the cover portion is made not to contact the inner tube, so that There is a slight gap between the lid and the inner tube, so there may be cases where the overflowing soup flows into the outer tube from the gap. 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. 1222512 [Summary of the Invention] Means for Solving the Problem In order to solve the foregoing problem, the present invention provides a pot bottom temperature sensor for a stove, including: an inner cylinder, which is blocked by 5 heat collecting plates abutting on the bottom surface of a conditioning container And an 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 does not contact the inner portion A gap is left between the lid portion and the inner cylinder, and an umbrella portion is formed outside the heat collecting plate to cover the gap from above and protrude upward from the lid portion without touching the lid 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 overlap with each other forms an inclined portion which is inclined downward toward the outside in the radial direction, the overflowing soup can also be prevented from passing between the lid portion and the inner tube along the gap between the umbrella portion and the lid portion. The gap 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 ministry sent to the heat collecting plate 81. In addition, since the gap 伞 between the umbrella portion 87 and the cover portion% is small, the space between the inner tube 82 and the outer tube 83 is substantially closed, and heat insulation can be ensured. Therefore, the influence of the heat from the gas burner 3 or the heat insulation barrel 9 on the temperature detection element 排除 is eliminated, and the temperature of the conditioning container p can be accurately detected by the temperature detection element 80. In addition, the umbrella portion 87 can prevent the overflow of soup from falling toward the gap 86 between the lid portion 85 and the inner tube 82. Furthermore, in the present embodiment, the portion where the umbrella portion "and the cover portion 85 overlap each other, that is, the portion of the outer peripheral edge of the umbrella portion 87 and the portion of the inner peripheral edge of the cover portion 85 are inclined downward and radially outward. The inclined portions 87a and 85a can prevent the overflowing soup from flowing between the umbrella portion 87 and the cover portion 85. Therefore, the overflowing soup can be reliably prevented from flowing between the cover portion 85 and the inner tube 82. The gap 86 flows into the outer cylinder 83. Also, the central portion of the heat collecting plate 81 of the temperature sensor 8 is mounted on the umbrella portion 87, and even if the bottom surface of the conditioning container p is slightly uneven, the center of the heat collecting plate 81 It can also abut the bottom surface of the conditioning container p surely. 5 Also, the aforementioned embodiment is that the flange 82a at the upper end of the inner cylinder 82 is fixed under the umbrella portion 87 by spot welding, but as shown in FIG. 3, The outer peripheral edge of the umbrella portion 87 may be crimped, and the flange 82a may be fixed to the lower surface of the umbrella portion 87 by the curled portion 87b.
