DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

The heating cooker 16 has a heating top surface 17 having an operating portion 13, a lower case 8 at the lower portion, and a heating portion 9 inside.

The heating top surface 17 is formed by a heating zone 18 and a non-heating zone 19, and the non-heating zone 19 is a top plate surface 20 of a non-crystallized glass material and is step-pressed with a V-shaped cross section in the central portion. The part 21 is provided.
On the other hand, the heating zone 18 is a crystallized glass 22 having a trapezoidal cross section, which is inserted into a stepped portion 21 provided on the top plate surface 20 and integrally joined by an adhesive 23.

Further, the ring body 23 has a V-shaped cross section, and is inserted between the step pushing portion 21 of the top plate surface 20 and the crystallized glass 22.

The operation of the configuration shown in FIGS. 1 to 3 will be described. When the heating cooker 16 turns on and off the operation SW14 and starts energization, the plurality of lamp heaters 12 inside the heating unit 9 generate heat and penetrate the crystallized glass 22 on the heating top surface 17 immediately above to cover a pot or the like. A heating object (not shown) is heated by radiation and conduction. To stop heating, turn the heating part on / off SW15 to O.

In this type of heating cooker, as described in FIGS. 19 to 20 of the conventional example, the heating top surface 2 is crystallized because the infrared rays of the lamp heater 12 are transmitted through the heating zone 3 and the temperature is high. In addition to the fog glass 5, the non-heating zone 4 was made of the same material in one piece.

This is because in order to integrate the non-heating zone 4 with the crystallized glass 5 in the heating zone 3 as a two-piece made of a different material, the joining portion has a flat feeling, the number of assembling steps is small, and the feeling of unity. This is because it is difficult to make the structure and shape such as the presence of such a thing.

On the other hand, in the present invention, the heating zone 18 and the non-heating zone 19 are made of different materials, and the crystallized glass 22 is used as the material of the heating zone 18 of the heating top surface 17. Amorphous glass is used as the material of the top plate surface 20 and is integrated.

Then, an O-ring-shaped ring body 26 having elasticity is provided in the recess A24 in the outer peripheral section of the crystallized glass 22.
Is inserted into the recess B25 of the step pressing portion 21 provided on the top plate surface 20 from the upper surface, and is fitted and joined integrally. At this time, the O-ring-shaped ring body 26 is prevented from coming off, and the upper surface portion of the crystallized glass 22 is in contact with the top plate surface 20 to provide a sense of unity.

As described above, according to the second embodiment, (1)
The crystallized glass in which the O-ring is fitted is inserted into the recess B of the stepped portion provided on the top plate surface from the top surface and integrated by fitting, so that a heating top surface with a small number of assembling steps can be provided. (2) Since a part of crystallized glass is placed on the top plate surface, a heated top surface with few bonding lines can be realized.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The difference from the third embodiment is that the inner peripheral side 27a of the donut-shaped plate 27 is bent toward the outer peripheral side 27b and the cross section is different from the one-piece metal ring 29 bent vertically downward 28 from the middle. Stepped convex shape 3
The crystallized glass 22 is No. 1.

Next, the top plate surface 20 is provided with two-step step pushing parts 32 and 33. And metal ring 2

I am looking forward to it. As a result, the metal ring 29
The vertical downward direction 28 is bent to prevent loosening when integrated.

Based on the above structure, the plate surface 27 of the metal ring 29, the upper surface of the crystallized glass 22 and the top plate surface 20 have the same height.

As described above, according to the fourth embodiment, (1)
By making the crystallized glass, the metal ring, and the top plate surface at the same height, it is possible to provide a heated top surface which is an integration of the three parts but has a flat feeling. (2) By using non-crystallized glass as the material for the top plate surface and by coordinating the materials and colors of the three parts,
It has effects such as realization of various heating top surfaces that are flat and inexpensive.

Next, a fifth embodiment of the present invention will be described with reference to FIG. The difference from the fourth embodiment is that the top plate surface 20 is limited to a metal material, and the two-piece metal ring 29 and the top plate surface 20 are completed into one piece.

Then, similar to the fourth embodiment, the crystallized glass 22 and the metal ring 29 each having a stepped convex shape 31 in cross section are used, and the top plate surface 20 is of a two-step type using an inexpensive material such as a zinc-treated steel plate. While providing step pushing portions 32 and 33, the outer peripheral side of the donut-shaped plate 27 of the metal ring 29 is placed on the first step 32 of the step pushing portion,
The other portion of the metal ring 29 integrated with the crystallized glass 22 in the vertically downward direction 28 is inserted into the slit portions 30 at a plurality of positions of the stepped portion and bent to be integrally coupled.

Thereafter, the surface of the crystallized glass 22 is masked, and the top plate surface 20 and the metal ring 29 are simultaneously powder-coated 34 to realize a one-piece feeling.

As described above, according to the fifth embodiment, (1)
The line of the joining portion between the crystallized glass and the metal ring and between the metal ring and the top plate surface is eliminated by the powder coating, so that a heated top surface with a sense of unity can be provided. (2) By adjusting the types of powder coating, various heating top surfaces can be realized.

Next, a sixth embodiment of the present invention will be described with reference to FIG. In the first to fifth embodiments, the crystallized glass, the metal ring and the three parts of the top plate surface are integrated, whereas in the sixth embodiment, the crystallized glass and the two parts of the top plate surface are integrated. It was done.

That is, the heating zone 18 and the non-heating zone 1
In the non-heating zone 19, the top plate surface 20 of the non-crystallized glass material is used as the non-heating zone 19, the inner peripheral side 35 is bent toward the outer peripheral side 36, and the vertical downward direction 37 is bent halfway.

On the other hand, the crystallized glass 22 in the heating zone 18 is inserted into the vertically downward direction 37 of the top plate surface 20, and the portion of the vertically downward direction 37 is bent to be integrated with each other.

As described above, according to the sixth embodiment, (1)
A part of the top plate surface is bent and integrated with crystallized glass to form a heated top surface with a small number of parts. (2) Furthermore, an inexpensive heating top surface with a small number of assembly steps can be realized. (3) The use of a steel plate laminated with fluorine on the top plate surface has the effect of eliminating the need for adhesives and surface treatments, and providing a simple construction method.

Next, a seventh embodiment of the present invention will be described with reference to FIG. Bend the inner circumference side 35 toward the outer circumference 36,

The difference from the embodiment is that they are joined by an adhesive agent 38 after being integrated.

At this time, one of the crystallized glasses 22 is brought into contact with the metal material serving as the top plate surface 20, and the other is bent to bond and integrate, but in order to bond them without a gap therebetween. It is preferable that the top plate surface 20 has a metal material plate thickness of 0.2 to 0.6 mm.

However, it is desirable that the top plate surface 20 on which a cooking container such as a pot is placed is as thick as 0.5 to 0.8 mm.

Therefore, in the case where the plate thickness is large, the processing equipment becomes large and the back spring at the time of bending becomes large, but there is a means for connecting them so that there is no gap between them, and to supplement the presence or absence of a gap after bending between them. There is a means for joining with an adhesive 38.

The seventh embodiment shows a means for joining with an adhesive 38, and in particular, an adhesive that cures at room temperature is used.

The top plate surface 20 is bent in the vertical downward direction 37 from the middle, and the crystallized glass 22 is inserted into the portion in the vertical downward direction 37, and the portion in the vertical downward direction 37 is bent to integrate and combine. The difference from the embodiment is that they are integrally connected via a cushioning material 39.

At this time, one of the crystallized glasses 22 is brought into contact with the metal material serving as the top plate surface 20, and the other is bent to bond and integrate them, but the bonding is performed at a position close to the heating section 9. , The temperature rises. At this time, the crystallized glass 22 has a small coefficient of thermal expansion and does not expand much,
The coefficient of thermal expansion of the metal material as the top plate surface 20 expands greatly.

Therefore, the loosened part is generated in the part which is bent and integrated. Conversely, it contracts at extremely low temperatures.

The eighth embodiment is integrated with the cushioning material 39 through the cushioning material 39, and corresponds to the above phenomenon.

As described above, according to the eighth embodiment, (1)
A part of the surface of the top plate is bent and bonded and integrated with the crystallized glass via a cushioning material, so that the difference in thermal expansion coefficient due to different materials is not absorbed and the crystallized glass is not damaged. (2) The cushioning material has an effect of absorbing the back spring during bending even when the plate thickness is large.

Next, a ninth embodiment of the present invention will be described with reference to FIG. The difference between the sixth embodiment and the eighth embodiment is that the upper surface of the crystallized glass 22 and the top plate surface 20 have the same height.

As described above, according to the ninth embodiment, (1)
By making the top plate surfaces of the crystallized glass and the non-crystallized glass at the same height, a heated top surface with a flat feeling is obtained.
