A frame-shaped upper case 2 is combined with the lower case 1 to form an exterior case that becomes the main body of the cooker, and a flat rectangular flat top plate 3 made of an insulating material is fitted into the upper case 2. Fixed.
When a cooking container is placed on the top plate 3 and the power is turned on, an eddy current is generated in the metal cooking container due to the magnetic flux generated by the electromagnetic coil placed on the bottom side of the top plate 3, and the cooking container is guided. It is now possible to cook by heating.

ートが案出されている。 By the way, the top plate 3 conducts heat from the heated cooking container, so if you accidentally touch the top plate after removing the cooking container, there is a risk of burns. This needs to be displayed. Therefore, a temperature-indicating paint is applied to the top surface of the top plate on which the cooking container is placed, creating a film that changes color and indicates danger when the top plate reaches a predetermined temperature of 40 to 60 degrees Celsius. A top plate has been devised.

い。<Problems to be Solved by the Invention> By the way, as a material for forming the temperature display part, there is a low-temperature type thermochromic material that changes color at 40 to 60°C, which may cause burns. However, when this thermochromic material reaches temperatures of around 100°C to 120°C, it deteriorates in a short period of time and no longer changes color. On the other hand, when cooking with this type of electromagnetic cooker, for example cooking with oil such as tempura, the top plate reaches a high temperature of about 200 to 250 degrees Celsius. Low-temperature thermochromic materials cannot be used for the top plate. In addition, if the operating environment exceeds 40 degrees Celsius, it will be susceptible to sunlight and cannot be installed near a window.

レートは実用化に至つていない。 On the other hand, in recent years, a new high-temperature thermochromic material has been developed that can withstand high temperatures of 600 to 800 degrees Celsius and is also resistant to sunlight. Since it does not change color, it cannot display any temperature in the temperature range of 60 to 100 degrees Celsius, where there is a risk of burns, and it is difficult to use color display for safety purposes. In this way, because there is no existing thermochromic material that can change color at 40 to 60 degrees Celsius and withstand temperatures as high as 300 degrees Celsius, which is necessary to form the above-mentioned temperature display section, Top plates using color display technology have not yet been put into practical use.

目的とするものである。<Purpose of the invention> The present invention was devised in view of these conventional problems, and although it uses the existing thermochromic material, it does not work when the top plate reaches a temperature of 40 to 60°C. In addition to displaying the color, 200
The object of the present invention is to provide a top plate for an electromagnetic cooker that can stably display the temperature even at high temperatures of ~250°C.

とができる。<Function> When this top plate is applied to an electromagnetic cooker for cooking, the magnetic flux generated by the electromagnetic coil also acts on the temperature measuring member of the temperature display section made of other conductive materials of the cooking container. Heated by induction. On the other hand, since the flat plate portion of the main body is heated by heat conduction from the cooking container, the rate of temperature rise is slower than that of the temperature measuring member.
That is, when the temperature of the flat plate of the main body reaches 40 to 60 degrees Celsius, the temperature of the temperature measuring member rises to about 120 degrees Celsius, and the high-temperature temperature indicator material, which has a discoloration temperature of 100 to 120 degrees Celsius, changes color due to heat conduction from the temperature measuring member. , indicates that the flat plate of the main unit has reached a dangerous temperature that could cause burns. That is, existing high-temperature temperature indicating materials that change color at temperatures of 100°C or higher can be changed in color when the flat plate portion of the main body is heated to 40 to 60°C.

支障は生じない。 When cooking by induction heating continues, the temperature measuring member reaches a constant temperature when it reaches its own Curie temperature of 120 to 300 degrees Celsius, so if the temperature display part becomes too high, the mechanical part of the induction cooker This can prevent harmful effects on food and cooking. At this time, the temperature indicating material maintains its discolored state due to heat conduction from the flat plate portion of the main body, which is heated to 100° C. or more due to heat conduction from the cooking container. In addition, when cooking tempura dishes, etc.
The temperature rises to 200-250℃, but high-temperature indicating materials
It has a high heat resistance of 600 to 800 degrees Celsius, so no problems will occur.

になつている。 Next, the effect will be explained. When this top plate is applied to an electromagnetic cooker, the cooking container 7 is placed on the main body flat plate part 4, the power is turned on, and the electromagnetic coil 5 is driven, the magnetic flux generated by the electromagnetic coil 5 acts on the cooking container 7. As a result, eddy currents are generated, and the cooking container 7 is heated by induction to perform cooking, and heat is conducted from the cooking container 7 to the top plate to heat the main body flat plate portion 4. On the other hand, since the temperature measuring member 6a of the temperature display section 6 is made of an iron-nickel alloy and is a conductive material as described above, an eddy current flows due to the magnetic flux generated by the electromagnetic coil 5 and is heated by induction, so that the temperature measuring member 6a of the temperature display section 6 is heated by induction. The temperature becomes higher than that of the main body flat plate portion 4, which increases in temperature due to heat conduction. That is, the temperature of the main body flat plate part 4 is 40 to 60°C.
When the temperature rises to a certain degree, the temperature measuring member 6a rises to about 120° C., and the high temperature type temperature indicator 6b on the surface of the temperature measuring member 6a changes color from yellow to orange. That is, 100~
By using the high temperature type temperature indicating material 6b which changes color at 120°C, it is possible to display the state in which the temperature of the main body flat plate part 4 has risen to 40 to 60°C, and it is designed to prevent accidental contact with the main body flat plate part 4.

して使用できる。 In addition, the two types of iron-nickel alloys shown as the temperature measuring member 6a were heated to temperatures of 120°C and 180°C, respectively.
Since the Curie temperature is 120℃ and 180℃
When the temperature rises to ℃, the magnetic permeability changes and transitions from ferromagnetism to paramagnetism, and even when cooking at high temperatures such as tempura, the temperature does not rise above 120℃ or 180℃, and electromagnetic properties due to overheating. There will be no interference with the mechanical parts of the cooker or with cooking. At this time, the temperature indicator 6b
maintains its discolored state due to heat conduction from the flat plate portion 4 of the main body heated to 100° C. or higher due to heat conduction from the cooking container 7. Furthermore, since the high-temperature temperature indicating material 6b is used, it can be installed and used near a window without being affected by sunlight.
また、第４図およびこれの一部拡大図を示した

面に接合状態に設けてもよい。 Further, as shown in FIG. 4 and FIG. 5 showing a partially enlarged view thereof, a ring-shaped temperature display section 6 consisting of a temperature measuring member 6a and a temperature indicating material 6b is provided in a bonded state on the upper surface of the main body flat plate section 4. You can.

題は生じない。 It should be noted that the present invention is not limited only to the above-mentioned embodiments, and it goes without saying that various embodiments are possible. For example, as a temperature measuring member for a temperature display section,
A stainless steel plate with a thickness of about 0.4 mm formed into a disk shape with a diameter of 90 mm may be used. In this case, the temperature of the temperature measuring member rises to about 300°C, but since the high temperature type temperature indicator 6b has a heat resistance temperature of 800°C, no particular problem occurs.

The existing high-temperature temperature indicator material, which has a high temperature resistance of ~800℃, is applied to the flat plate of the main body in a thermally conductive contact state, and this temperature indicator is connected to the electromagnetic coil on the top surface of the flat plate of the main body. Since it is installed on the opposite part of the top plate, there is a risk of burns to the flat part of the main body of the top plate even though high-temperature indicating material is used.
It is possible to change color when the temperature rises to ℃,
Moreover, since a high-temperature temperature indicating material is used, it has excellent light resistance, and a top plate equipped with a color display temperature sensor can be put to practical use.
