Problems to be Solved by the Invention In the conventional configuration as shown in FIG. 3, the opening and closing surface is large, making it easy to clean the inside of the baking chamber, but the thermal efficiency is poor, requiring more heat than necessary, and causing uneven baking. There was a problem that it was easy to occur. In addition, in the conventional configuration shown in Figure 4, the opening and closing surface is a small upper surface, and by configuring the heater on the outside surface of the firing chamber, it is possible to easily clean the inside of the firing chamber and reduce heat loss due to the opening and closing surface. However, by configuring the heater on the outer surface of the firing chamber, there was a problem that heat loss was large and the heat adversely affected the main body case, and the upper part of the object to be fired could not be heated.

The present invention is intended to solve these problems, and aims to reduce heat loss during heating as much as possible, and to provide a structure that allows easy cleaning of the inside of the firing chamber.

Means for Solving the Problem In order to solve this problem, the present invention installs a heater inside the firing chamber, and also reduces the size of the firing chamber by providing an inclined part on the side of the firing chamber below the heater mounting section. It is structured like this.

Function: With this configuration, opening and closing is done from a small surface on the top surface, and the contact surface between the firing chamber and the lid is also small, which reduces heat loss.When cleaning from above, the lower part of the heater is tilted. To provide an automatic bread maker having a baking chamber that prevents materials such as flour from scattering and accumulating and which can be easily cleaned even if it becomes dirty.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In Fig. 1, 31 is the main body;

Power is transmitted to the dog pulley 36 via.

Further, a heater 37 is fixed to the side surface of the chassis 32 via a heater fixing insulator 38, and a temperature detection section 40 is elastically supported so as to come into pressure contact with the side surface of the bread baking mold 39.
The firing chamber 41 is fixed. This firing chamber 4
1 is fixed to the chassis 32 and has a dog pulley 36 on the inner bottom.
．． A pan-shaped bone that pivotally supports the pulley shaft 42 and the lower connector 43 is provided with a stand 44 .

Also, the side surface of the firing chamber 41 is tilted at a position slightly below where the heater 37 is attached, gradually reducing the firing chamber space, so that the inner dimension of the heater 37 is smaller when viewed from above as shown in Fig. 2. It has been reduced to. (A>C>A',
B>D>B') (It is better to reduce the temperature detection part 40 side to the inside of the temperature detection part 4o, but the heater 37
If there is a difference in height between the temperature sensing portion 4o and the temperature sensing portion 4o, there is no need to reduce the temperature sensing portion 4o to the inner part. ) A tray 63 is attached to the bottom of the reduced firing chamber 41.

The bread baking mold 39 has an upper connector 45 for transmitting the power of the motor 33 at the bottom, a spring shaft 46, and a removable kneading blade 47, and the bread mold rib is removably fitted to the base 44.

Further, on the upper surface of the firing chamber 41, there is a lid that can be opened and closed, a mounting shaft 49 that protrudes from the center of the lower surface, and an inner lid 61 that is elastically supported by a pressing spring 50, so that the lid 48 can be closed. As a result, the lower surface of the outer periphery of the inner lid 61 is brought into pressure contact with the plane of the upper step of the firing chamber 41. Furthermore, the lid body 48
There is an opening knob 62 and a latch 63 for opening the lid body 48.
