It is formed to enhance the heat shielding effect. Further, as shown in FIG. 3, tongues 18 bent toward the door frame 4 are provided on both side edges of the first heat shield plate 13, and as shown in FIG. A gap is formed between the plate 13 and the door frame 4 to enhance the heat shielding effect.

図４においては第１遮熱板１３のみを示しているが、図４に示すように、第１遮熱板１３には、複数の連結部用挿通孔１９が形成されている。該連結部用挿通孔１９は、連結部１１（図２示）の外径よりも大径に形成されており、図２に示すように、連結部１１が間隙を存して挿通孔１９に挿通されるようになっている。   Although only the first heat shield plate 13 is shown in FIG. 4, as shown in FIG. 4, the first heat shield plate 13 has a plurality of connecting portion insertion holes 19. The connecting portion insertion hole 19 is formed to have a larger diameter than the outer diameter of the connecting portion 11 (shown in FIG. 2). As shown in FIG. 2, the connecting portion 11 has a gap in the insertion hole 19. It is designed to be inserted.

第２遮熱板１４は、図２及び図３に示すように、把持部８の位置に対応して設けられており、グリル庫から把持部８への熱を一層確実に遮断する。該第２遮熱板１４の両側縁には、第１遮熱板１３に向って折り曲げられた連結片２０が複数設けられ、該連結片２０を介して第１遮熱板１３との間に空隙を存して第１遮熱板１３に連結されている。また、図３に示すように、第２遮熱板１４においても、第１遮熱板１３と同様に、連結部１１が間隙を挿通される複数の連結部用挿通孔２１が形成されている。   As shown in FIGS. 2 and 3, the second heat shield plate 14 is provided corresponding to the position of the grip portion 8, and more reliably blocks heat from the grill box to the grip portion 8. A plurality of connecting pieces 20 bent toward the first heat insulating plate 13 are provided on both side edges of the second heat insulating plate 14, and the first heat insulating plate 13 is interposed between the connecting pieces 20. There is a space between the first heat shield plate 13 and the first heat shield plate 13. Further, as shown in FIG. 3, in the second heat shield plate 14, similarly to the first heat shield plate 13, a plurality of connecting portion insertion holes 21 through which the connecting portions 11 are inserted through the gaps are formed. .

以上のように構成されたグリル扉１は、図２を参照すれば、扉枠４と前面パネル５との間に遮熱部材１２が介在されているので、グリル庫の熱を遮熱部材１２により遮断して前面パネル５が熱くなるのを防止することができる。このとき、把持部８においては、前記第１遮熱板１３に加えて第２遮熱板１４によっても熱が遮断され、把持部８に手が触れたときの熱さを確実に軽減することができる。また、把持部８を把持する際には、ガラス板７の下縁を覆う覆縁壁９に手が触れることが考えられるが、第１遮熱板１３の前記縁片１５によってガラス板７の熱が吸収放熱され、覆縁壁９が高温となることが防止されるので、覆縁壁９に手が触れたときの熱さによる不快感を確実に減少させることができる。   Referring to FIG. 2, the grill door 1 configured as described above has a heat shield member 12 interposed between the door frame 4 and the front panel 5, so that the heat of the grill box is removed from the heat shield member 12. Therefore, it is possible to prevent the front panel 5 from becoming hot by blocking. At this time, in the gripping portion 8, heat is blocked by the second heat shield plate 14 in addition to the first heat shield plate 13, and the heat when the hand touches the grip portion 8 can be reliably reduced. it can. Further, when gripping the gripping portion 8, it is conceivable that the hand touches the covering wall 9 that covers the lower edge of the glass plate 7, but the edge piece 15 of the first heat shield plate 13 causes the glass plate 7 to be touched. Since heat is absorbed and dissipated and the covering wall 9 is prevented from reaching a high temperature, discomfort due to heat when the hand touches the covering wall 9 can be reliably reduced.

なお、本実施形態においては、第１遮熱板１３及び第２遮熱板１４を金属製として放熱・遮熱作用を得ているが、特に、第１遮熱板１３と第２遮熱板１４との両方、或いは何れか一方をアルミニウムによって形成することにより、放熱効果を一層向上させることができる。   In the present embodiment, the first heat shield plate 13 and the second heat shield plate 14 are made of metal to obtain a heat radiation / heat shield action, but in particular, the first heat shield plate 13 and the second heat shield plate. By forming both or one of them with aluminum, the heat dissipation effect can be further improved.

また、本実施形態においては、前記遮熱部材１２を第１遮熱板１３と第２遮熱板１４とによって構成したが、更に、図示しないが、第１遮熱板１３と第２遮熱板１４だけでなく他の遮熱板を追加配設してもよい。また、例えば、前述のように、アルミニウム等の放熱作用の大きな材料を用いた場合等には、図４に示すように、第１遮熱板１３のみを設けて把持部８の加熱を十分に防止することができる。   In the present embodiment, the heat shield member 12 is constituted by the first heat shield plate 13 and the second heat shield plate 14. Further, although not shown, the first heat shield plate 13 and the second heat shield plate are also shown. In addition to the plate 14, other heat shield plates may be additionally provided. For example, as described above, when a material having a large heat dissipation function such as aluminum is used, as shown in FIG. 4, only the first heat shield plate 13 is provided to sufficiently heat the grip portion 8. Can be prevented.

また、図２に仮想線示するように、前記第２遮熱板１４の上縁をガラス板７と扉枠４との間に延出させて他の縁片２２ａを設け、或いは、前記第２遮熱板１４の上縁をガラス板７と扉枠４との間に起立させて他の縁片２２ｂを設けて、グリル庫からガラス板７への熱を遮るようにしてもよい。これにより、ガラス板７の温度上昇を抑えて前面パネル５の加熱を一層確実に防止することができる。更にまた、図示しないが、第２遮熱板１４の上端部（例えば、前記他の縁片２２ａ又は２２ｂ）をガラス板７の内面側に接触させることで、ガラス板７の熱を第２遮熱板１４により吸収放熱することができ、第１遮熱板１３の縁片１５を設けることなく覆縁壁９の温度上昇を抑えることができる。   Further, as shown in phantom lines in FIG. 2, the upper edge of the second heat shield 14 is extended between the glass plate 7 and the door frame 4 to provide another edge piece 22a, or the second (2) The upper edge of the heat shield plate 14 may be raised between the glass plate 7 and the door frame 4 to provide another edge piece 22b to block heat from the grill box to the glass plate 7. Thereby, the temperature rise of the glass plate 7 can be suppressed and heating of the front panel 5 can be prevented more reliably. Furthermore, although not shown, the upper end portion of the second heat shield plate 14 (for example, the other edge piece 22a or 22b) is brought into contact with the inner surface side of the glass plate 7, so that the heat of the glass plate 7 is second shielded. The heat plate 14 can absorb and radiate heat, and the temperature rise of the covering wall 9 can be suppressed without providing the edge piece 15 of the first heat shield plate 13.

また、図示しないが、前記第１遮熱板１３或いは第２遮熱板１４に、ガラス板７の下縁に接触する接触片を設けることによっても、ガラス板７の熱を吸収放熱することができ、その放熱作用が十分であれば第１遮熱板１３の縁片１５や前述した第２遮熱板１４の他の縁片２２ａや２２ｂを設けなくてもよい。   Moreover, although not shown in figure, the heat of the glass plate 7 can be absorbed and radiated also by providing the first heat shield plate 13 or the second heat shield plate 14 with a contact piece that contacts the lower edge of the glass plate 7. If the heat dissipation action is sufficient, the edge piece 15 of the first heat shield plate 13 and the other edge pieces 22a and 22b of the second heat shield plate 14 described above need not be provided.
