The upper end of the main body case 20 is fixed to the outside of the convex portion 41 formed on the lower surface, and the upper portion of the main body case 20 is fixed to the upper portion of the main case 20.
The upper end of the oven 50 is fixed by screws 42 inside the inside. A peripheral wall 43 is formed integrally with the outer peripheral edge of the upper surface of the oven ring 40, and a plurality of steam vent holes 44 are formed in the peripheral wall 43. Reference numeral 32 denotes a reflection plate mounted inside the upper lid 30. Firing case 6
The 0 stirring blade 70 is rotated by a drive motor 80 via pulleys 72 and 82 fixed to respective shafts 71 and 81 and a belt 83 to knead the bread material. At the upper end of the shaft 71 of the stirring blade 70, a temperature sensor 65 such as a thermistor, which is a temperature detecting means for detecting the dough temperature of the bread material, is attached. Further, between the baking case 60 and the oven 50, a heating means 66 composed of a heater for baking the bread material is arranged. In addition, a chassis 22 is disposed at a predetermined distance from a bottom wall 21 of the main body case 20 at a bottom inside the main body case 20 (apparatus main body), and a shaft 81 of a drive motor 80 and a stirring blade 70 are provided on the chassis 22. A shaft 71 is rotatably supported. In the bread maker 10 configured as described above, in the joint structure of the oven and the chassis according to the present embodiment, as shown in FIGS. 1 and 2, a main body case (apparatus main body).
The vibration generated when the bread material is kneaded by the rotational drive of the drive motor 80 and the rotation of the stirring blade 70 is formed at the joint between the chassis 22 of FIG. 20 and the oven 50 in which the baking case 60 having the stirring blade 70 is provided. A vibration absorbing member 90 made of an elastic material such as synthetic rubber for absorbing is provided. The chassis 22 and the oven 50 are joined by a plurality of mounting screws 96 and nuts 95, and the above-described vibration absorbing material 90 is provided at a joint between the mounting screws 96 and the nut 95. That is, the mounting screw 96 penetrates a substantially central portion of the vibration absorbing material 90, and the nut 95 is screwed into the lower end of the mounting screw 96 and tightened, so that the vibration absorbing material 90 is disposed in a fixed state. ing. The vibration absorbing material 90 is not limited to the one provided at the joint portion by the mounting screw 96 and the nut 95, and may be provided at a portion near the joint portion by the mounting screw 96 and the nut 96. In this case, a double-sided adhesive tape is stuck on both upper and lower surfaces of the vibration absorbing material 90 so that the vibration absorbing material 90 is attached to the chassis 22 and the oven 5.
