HEATING COOKER

PROBLEM TO BE SOLVED: To improve cleanability while ensuring the size of a heating chamber, in a heating cooker that feeds hot air generated in a combustion chamber to the heating chamber and circulates the hot air to perform heating cooking.SOLUTION: A heating cooker includes: a body part 20 that has an upper wall 33, a lower wall 34, a horizontal side wall 35 and a rear frame 38; a front frame 37 that is provided to the front opening end of the body part; and a distribution plate 36 that is connected to the rear opening end thereof. Boundary portions 20a between the upper and lower walls 33, 34 and the horizontal side wall 35 are made into a corner R part, the rear frame 38 is formed into a taper cylindrical shape so as to make its opening cross sectional area smaller toward the distribution plate 36, and a peripheral wall 361 is provided from the periphery of the distribution plate 36 toward the rear opening end of the rear frame 38 via the corner R part. 【課題】燃焼室で発生させた熱気を加熱室に送り込み循環させて加熱調理を行なう加熱調理器において、加熱室のサイズを確保しながら、清掃性を向上させる。【解決手段】上壁(33)、下壁(34)、左右側壁(35)及び後枠(38)を有する本体部(20)と、その前方開口端に設けられる前枠(37)と、後方開口端に接続される分布板(36)を備え、上壁(33)(34)と左右側壁(35)との境界部分(20a)はコーナＲ部とし、後枠(38)を分布板(36)に向かって開口断面積が小さくなるテーパ筒状に形成すると共に、分布板(36)の周囲から後枠(38)の後方開口端に向かって周壁(361)をコーナＲ部を介して設けたこと。【選択図】図４
