A device having a through-hole for inserting the handle is used, while a part of the handle protrudes to the outside through the through-hole, and a heat insulating material is interposed between the inner periphery of the through-hole and the handle. The method is characterized in that after the cooking utensil is housed in the firing furnace, the firing furnace is heated.
(実施例)
以下本発明を図面に示す実施例に基き具体的に説明する
。(Example) The present invention will be specifically described below based on an example shown in the drawings.
第1図及び第2図は本発明方法が実施される焼成炉12
の1例を示している。Figures 1 and 2 show a firing furnace 12 in which the method of the present invention is carried out.
An example of this is shown.

大きさを有している。The main body of the firing furnace 12 includes a main container 2 having a heat-insulating structure and a main container 2.
The lid body 16 has an insulating structure and is attached via a hinge 15 so as to be openable and closable in the vertical direction.The soaking chamber 1 in the internal space stores one cooking utensil A having a handle a such as a frying pan. It has a size that allows the coating layer C to be fired.
蓋体16の頂壁3の略中央には、排気管4を貫通固定し
、その下端を均熱室1内に突出させている。An exhaust pipe 4 is fixedly penetrated approximately at the center of the top wall 3 of the lid 16, and its lower end projects into the soaking chamber 1.

ガスバーナ9には配管8.8を通じてプロパンガスなど
のガス燃料が供給される。A gas burner 9 is disposed on the bottom wall 6 of the main passenger appliance 2, and an air intake lower is provided in the bottom wall 6. Gas fuel such as propane gas is supplied to the gas burner 9 through a pipe 8.8.

A large number of small holes 13 are formed in the gas burner 9.
The structure is such that the hot air generated by the erupting flame spreads throughout the soaking chamber 1 and rises.
又主容器2と蓋体16との合せ面に前記柄aを挿通する
ための切欠部5a、 5bを設けている。Further, notches 5a and 5b are provided on the mating surfaces of the main container 2 and the lid 16, through which the handle a is inserted.

最適であることは云うまでもない。The amount of downward protrusion of the exhaust pipe 4 is preferably selected such that its lower end is located at approximately the same height as the opening edge 18 of the cooking utensil A, or slightly lower than this. This shows the case where the bottom end is inserted about 1/3 of the depth of the container of cooking utensil A, which has been experimentally confirmed to shorten the baking time the most and prevent uneven baking. . On the other hand, as the lower end setting position of the exhaust pipe 4 moves upward away from the opening edge 18, the firing time becomes longer, but as long as the firing time is kept within loCII, there is almost no problem in practice. Also, the lower end of the exhaust pipe 4 is the opening edge 1 for cooking utensils.
Needless to say, positioning it at the center of the center is optimal from the standpoint of both heat uniformity and thermal efficiency.

欠部で前記貫通孔5を構成することなどが可能である。The firing furnace 12 configured as described above has notches 5a and 5b provided in each side wall 22 at the mating surface of the main container 2 and the lid body 16 to form a through hole 5 through which the handle a is inserted. However, it is also possible to configure the through hole 5 with a notch provided in either the main container 2 or the lid 16.

なっている。Next, one method of implementing the present invention, which is carried out using the firing furnace 12 having the above configuration, will be explained. In this example, the processing target is a frying pan A having a heat-resistant grip part formed at the tip of the handle a.

に接する位置に巻き付けられる。As shown in FIG. 4, the cooking utensil A, on which the base treatment, primer treatment, and pre-drying treatment have been sequentially performed, and on which the fluororesin has been applied and the coating layer C has been formed, is heated in the firing furnace 12, as shown in FIG. A heat-resistant glass fiber (insulating material) as a heat insulating material 19 is wrapped around the handle a at an appropriate location. As shown in FIG. 3, the heat-resistant glass fiber 19 is wound to a thickness that substantially closes the through hole 5, and is also wound at a position in contact with the inner periphery of the through hole 5.

炉12の外部に位置することは云うまでもない。After making the above preparations, as shown in FIGS. 1 and 2, a part of the handle a is projected to the outside through the through hole 5, and there is a space between the inner periphery of the through hole 5 and the handle a. The cooking utensil A is housed in the firing furnace 12 with a heat-resistant glass fiber (insulating material) 19 interposed therebetween. Needless to say, the grip portion is located outside the firing furnace 12 at this time.

結果、焼成処理は良好且つ能率的なものとなる。Next, the coating layer C can be fired by igniting the gas burner 9 and heating the soaking chamber 1 for a predetermined period of time. At this time, the hot air generated by the flame of the gas burner 9 rises in the soaking chamber l, and the top wall 3
However, since the exhaust pipe 4 protrudes downward, it turns downward and hits the coating layer C of the cooking utensil A, then changes direction again and is collected in the exhaust pipe 4 and discharged to the outside. Ru. The flow of hot air is excellent in applying heat effectively to the coating layer C, and is also excellent in applying heat evenly to the coating layer C. As a result, the firing process is good and efficient. becomes.
焼成中、均熱室l内は非常に高温になっているが、前記

冷却されることと、均熱室1からの輻射熱が前記断熱材
19によって遮断されることによるものと思料される。During firing, the temperature inside the soaking chamber l is extremely high, but the part of the handle a that protrudes to the outside does not reach such a high temperature that it can be touched by hand even in an actual test. temperature. This is because the effect of heat transfer through the handle a is small, the part of the handle a that protrudes outside is cooled by the outside air, and the radiant heat from the soaking chamber 1 is blocked by the heat insulating material 19. It is thought that.
ちなみに、前記断熱材19を除去した状態で焼成する実
験を行ったところ、輻射熱の影響を受けて、柄aの外部

握り部すが変質するという結果を招来した。Incidentally, when we conducted a firing experiment with the heat insulating material 19 removed, the part of the handle a that protruded to the outside became extremely hot due to the influence of radiant heat, and the synthetic resin grip part This resulted in a change in quality.

るように構成してもよい。As described above, when the method of the present invention is used, even when firing the cooking utensil A equipped with a heat-resistant grip, the tip of the handle a is made to protrude outside the firing furnace 12, and the heat insulating material 19 is used to radiate heat. As a result, the temperature rise of the tip can be suppressed by blocking the temperature of the tip, so that the firing can be performed properly. For example, asbestos, clay, or the like can be used as the heat material 19. Further, as shown in FIG. 5, a heat insulating material 19 is fixed to the upper and lower inner circumferences of the through hole 5, so that when the lid 16 is closed, the heat insulating material 19 is attached to the periphery of the handle a of the cooking utensil A. It may be configured such that it is in pressure contact with the.
