Description

[Detailed description of the invention] This invention is a hot-spot device in which the heater is sandwiched between the back side of the heating plate and the support plate, and the heater is fixed by tightening nuts on a plurality of bolts that pass through the heating plate and the support plate. Regarding plates, in particular, it is related to the temperature-sensing part attachment device of the temperature-sensing device that senses the temperature of the heating plate and controls the energization of the heater. Aimed at warmth. An embodiment of the present invention will be described below based on the drawings. As shown in an exploded perspective view in Fig. 1, 1 is a heating plate whose upper surface is a surface on which food is placed, 2 is a sheathed heater bent into an irregular meandering shape, and 3 is a heater 2.
A plurality of bolts protrudes downward from the back surface of the heating plate 1, avoiding the area where the heating plate 1 is placed. Reference numeral 4 denotes a support plate having an area covering the heater 2, and has a vertically elongated opening 5 bored in the central part. . 6 is a temperature sensing part of a temperature sensing device that senses the temperature of the heating plate 1 and controls the energization of the heater 2; 7 is a cylindrical body formed hollow into which the temperature sensing part 6 is inserted and has a flat surface 7A ; , 8 is the opening 5
Glass wool insulation, with a larger area
Reference numeral 9 denotes a holding plate, which is a holding surface 9 of the cylinder body 7 formed in a V shape.
It has A. 10 is a tightening nut for the bolt 3. In the above configuration, the heater 2 and the temperature sensing section 6
To install the heating plate 1, turn the heating plate 1 upside down and place the heater 2 on the back side of the heating plate 1. Then, the support plate 4 is passed through the bolt 3, and the heater 2 is held between the heating plate 1 and the support plate 4. Furthermore, the opening 5 of the support plate 4
The cylindrical body 7 into which the temperature sensing part 6 has been inserted is placed on the back surface of the heating plate 1. At this time, the flat surface 7A of the cylinder 7 is brought into contact with the heating plate 1. After that, the opening 5 is covered with a heat insulating material 8, and the bolt 3 is passed through the holding plate 9 , so that the heat insulating material 8 is held between the holding plate 9 and the support plate 4, and the V-shaped holding surface 9A is made of heat insulating material. 8
The cylindrical body 7 is held between the heating plate 1 and the heating plate 1 through the cylindrical body 7. Finally, by tightening the nuts 10 to the bolts 3, the support plate 4 connects the heater 2 to the heating plate 1.
, and the pressing surface 9A of the pressing plate 9 presses the cylinder 7 against the heating plate 1. Thus, the heater 2 is fixed between the heating plate 1 and the support plate 4, and the cylindrical body 7 is fixed between the heating plate 1 and the holding plate 9 , completing the installation of the temperature sensing section 6. Note that the presser plate 9 is fastened together with the support plate 4 at fewer points than the support plate 4, and the fixation of the heater 2 by the support plate 4 will not be released by removing the presser plate 9 . As described above, the present invention can achieve simultaneous fixation of the heater and the cylinder by fastening together the support plate of the heater and the holding plate of the cylinder into which the temperature sensing part is inserted. If the heater malfunctions, you can remove only the holding plate and take out only the cylinder through the opening drilled in the support plate and replace the temperature sensing part without releasing the fixation of the heater by the support plate, making the installation and removal work extremely easy. It will improve. Further, since the flat surface formed on the cylinder is in contact with the heating plate, stability is improved, and since the contact area with the heating plate is increased, accurate temperature sensing operation can be performed. Furthermore, since the pressing surface is formed in a V shape, the cylindrical body does not shift laterally, making the fixation even more reliable. Furthermore, since heat transmitted through the bolts, support plate, and presser plate is blocked by the heat insulating material, the temperature sensing portion can reliably respond to the temperature of the heating plate and perform accurate temperature control.
