The permanent magnet 6 is fixed to a magnet yoke 8 with a magnet cover 7, and the magnet yoke 8 has a magnet rod 9, which has the role of transmitting the attraction and detachment of the permanent magnet 6 to another control unit (not shown). are doing.
With the above structure, the heat on the outer bottom surface of the heating container is first received by the heat receiving portion 2 and then transferred to the soft ferrites 3 and 3' made of soft magnetic iron oxide. Also soft ferrite 3,3'
If it is made as thin as one leg or less, it will break on impact and warp will occur during firing during manufacturing, so a thickness of two to three legs is required. It is not possible to make large-area products because they tend to warp.
Therefore, in order to obtain the desired adsorption force, it is necessary to use two small soft ferrites, and three soft ferrites are required.
, 3' have limits on both area and thickness. Furthermore, if the heat capacity is large, the temperature rise will be slow and insensitive, so there is a size limit. Furthermore, it has various drawbacks, such as the need for a ferrite cover 4 because it is susceptible to impact. The present invention solves the above-mentioned drawbacks and provides an excellent heat-sensitive device.The present invention will be explained below with reference to Examples. FIG. 2 shows the thermal device 1 of the present invention.

たが、次の如き特徴を有している。The water for cooking rice goes from ioooo to water eventually disappearing from the bottom of the rice cooking pot 23, and then the temperature at the bottom of the rice cooking steel 23 rises to over 100°C, and the temperature of the heat receiving part 11 of the heat sensitive device blade Q also drops to the outside of the rice cooking pot 23. The temperature rises as the bottom surface rises, and when it reaches the Curie point of the heat receiving part 11, it loses most of its magnetic permeability, and the heat receiving part loses its magnetic permeability due to the loads of the valve spring 31 of the main valve 26, the main lever 19, the permanent magnet 12, the magnet rod 15, etc. The attraction force between the magnet 1 and the permanent magnet 2 is lost and they separate.Then, the main burner 24 and the ignition burner 29 are extinguished.Only the heat retention burner 30 is burning, and then the uneven time 10 to 1
After 5 minutes, when the heat retention lever 28 is raised, the heat retention valve 27 is closed, all gas is completely stopped, and the rice cooking is completed. The structure and function of the gas rice cooker using the present heat-sensitive device 10 have been described above, and it has the following characteristics.

にくいものとなる。Therefore, if the Curie point is the same, the Curie point can be reached faster in the first heat receiving part than in the conventional aluminum heat receiving part through heat transfer with the soft magnetic iron oxide soft ferrite 373r. . The sensitive magnetic alloy of the heat receiving part 11 is made of a thinner material, and the heat transfer is faster and the accuracy can be improved compared to the conventional example. Since the heat-sensitive device 10' does not require a ferrite cover and the anodized aluminum heat-receiving part 2 can be omitted, the processing cost can also be reduced. Since the soft ferrite 8;3' does not have the tendency to break due to impact, which is the biggest drawback, it is possible to eliminate critical complaints regarding the manufacturing quality and use of the heat-sensitive device 10. Since it uses a European magnetic alloy, it has the advantage of being easy to cut, bend, etc.
It is possible to create a heat-sensitive device 18 that has great utility value and greatly contributes to both cost and quality.As described above, in the present invention, the heat-receiving section itself is made of a European magnetic alloy having a set Curie point. Compared to the conventional method in which soft ferrite is provided under the heat receiving part, there is no problem of cracking of the soft ferrite and the need for a cover to prevent the cracking, and since the present invention directly detects heat, the detection sensitivity is also high. Furthermore, since the permanent magnet is covered by the heat-receiving part and the case, it is less susceptible to dirt, and as a result, performance fluctuations such as a decrease in the adsorption force with the heat-receiving part are less likely to occur.
