I do.
- the pot 140 or the like is induction-heated as described above, it is assumed that the ambient temperature below the top plate 115, that is, the inside of the induction heating cooker main body rises to, for example, a maximum of 60 ° C. As a result, the metal member of the fluorescent display tube 123 is heated to some extent by the alternating magnetic field generated by the heating coils 112 and 113, thereby setting the temperature to rise to 10 ° C. .
- the horizontal distance D1 between the fluorescent display tube 123 and the heating coils 112 and 113 also affects the degree of induction heating, and the larger the distance D1, the more difficult it is for induction heating to occur. If Dl is increased, the size of the fluorescent display tube 123 must be reduced accordingly. Therefore, if the limit is set to, for example, 20 mm and Dl is changed to 10 mm or 5 mm, the degree of temperature rise will increase.
- the fluorescent display tube 123 is arranged such that the front side of the display surface glass 123d is separated from the lower surface of the top plate 115 by 2 mm or more.
- the top plate 115 is instantaneously bent. Therefore, by separating them by 2 mm or more, even if the top plate 115 is bent, it is possible to prevent the portion from contacting the display surface glass 123d.
- ferrites 135 and 136 are arranged below heating coils 112 and 113, and fluorescent display tube 123 is arranged below top plate 115 made of a translucent material. Then, at least a part of the metal member forming the fluorescent display tube 123 is configured to be located below the upper surface position of the ferrites 135 and 136.
- the fluorescent display tube 123 has a high degree of freedom of display without restriction of the viewing angle unlike a liquid crystal display, it is possible to improve the design of the induction heating cooker. Then, on the lower side of the top plate 115, the influence of the magnetic flux which goes out of the side surface of the ferrites 135 and 136 and goes around to the upper side of the top plate 115 hardly affects the fluorescent display tube 123. Can be prevented from being excessively heated by induction, and the lifetime of the fluorescent display tube 123 can be guaranteed.
- the upper end position of the lead pin 123a constituting the fluorescent display tube 123 is Since it is located below the upper surface of 36, it is possible to prevent induction heating of the lead pin 123a, which is a relatively large component of the metal members constituting the fluorescent display tube 123, and to avoid a rise in temperature in a favorable manner. Can be. Furthermore, since the sealing lid 1231 of the fluorescent display tube 123 is arranged on the lower glass substrate 123f, the sealing lid 1231 and the frit glass 123 ⁇ are prevented from being inductively heated, and the hermetic sealing of the fluorescent display tube 123 is prevented. Can be maintained.
- the front side of the display surface glass 123d constituting the fluorescent display tube 123 is disposed so as to be separated from the lower surface of the top plate 115 by at least 2 mm, even if the top plate 115 is bent, the deflection is not affected. It is possible to prevent the portion from contacting the display surface glass 123d, and to prevent the fluorescent display tube 123 from being broken.
- the present invention is not limited to the above-described embodiment, but can be modified as follows.
- the filament 123e of the fluorescent display tube 123 is positioned below the upper surface of the ferrites 135 and 136. May be.
- the setting in FIG. 8 is merely an example, and may be appropriately changed and performed according to individually assumed conditions.
- the fluorescent display tube 123 may have a configuration in which the phosphor 123h, the anode electrode 123k, the insulating coating 123 ⁇ 4, the internal wiring 123g, and the like are arranged on the inner side of the display surface glass 123d.
- the rigidity of the top plate 115 is sufficient, it is not necessary that the front side of the fluorescent display surface glass 123d is separated from the lower surface of the top plate 115 by 2 mm or more.
- the arrangement of the display section using the fluorescent display tube 123 is not limited to that shown in FIG. 9, and may be arranged, for example, at the corner of the top plate 115 or between the heating sections 116 and 117.
- the cooking device according to the present invention is suitable as a cooking device used in a home kitchen, and is particularly useful as a built-in cooking device incorporated in a kitchen cabinet. .
