Description

TECHNICAL FIELD OF THE INVENTION The present invention is designed to automatically perform a series of steps of kneading, fermentation, and baking only by adding a predetermined material so that freshly baked bread is completed at a desired time. It relates to a bread maker.

2. Description of the Related Art A conventional bread maker of this type is constructed as shown in FIGS. That is, in FIG. 4, 1 is a bread making machine main body, 2 is a baking chamber installed in the main body 1, and a baking case 4 for accommodating bread ingredients is attached to and detached from the baking chamber 2 via an installation table 3. It is installed freely. 5 is a lid that covers the upper opening of the baking chamber 2 so as to be openable and closable, and 6 is a substantially U-shaped heater. The heater 6 is a sidewall of the baking chamber 2 and a baking case 4.
It is located between the side wall and the both ends of the baking chamber 2.
It is attached to one side wall inside. 7 is the firing case 4
The temperature detector 7 detects the temperature of the heater 6. The temperature detector 7 is provided on one side wall inside the baking chamber 2 between the both ends of the heater 6 as shown in FIG. 8 is the heater 6
It is a supporting portion for supporting the bent portion 6a of the above, and is attached to the inner side wall of the baking chamber 2. Reference numeral 9 is a control device.
Controls the energization of the heater 6 based on the detection result of the temperature detection unit 7, and also performs kneading, curing, fermentation,
It controls each step of firing.

Problems to be Solved by the Invention In the above-described conventional bread maker, since the heater 6 is formed in a substantially U shape, and the winding pitch of the heater 6 is generally the same as shown in FIG. Looking at the temperature distribution of each part of the heater 6, the temperature of the part located in the central part of the heater 6, that is, the bent part 6a of the heater 6, becomes higher than that of the other parts, and the temperature during firing is about At 270 ° C
The temperature of the other parts was about 230 ° C. Therefore, when the bread is baked by the heater 6, the baking color of the side surface of the bread corresponding to the bent portion 6a of the heater 6 becomes dark, while
There is a problem that the baking color of the side of the bread corresponding to other parts becomes lighter, and there is a problem that the baking color of the side of the bread becomes unbalanced.To solve this, place the temperature detection part close to the heater. If the temperature is to be controlled, the following problems occur in the kneading, kneading of the dough, and the fermentation process, and the temperature detecting unit cannot be placed close to the heater. For example, when the outside air temperature in winter is low, it is necessary to energize the heater for a short time to raise the temperature of the bread dough, but since it is close to the heater, even if the heater is de-energized, the accurate temperature of the bread dough is detected due to its preheating. Can not.

The present invention has been made in view of such problems, and an object thereof is to provide a bread maker capable of eliminating the imbalance of the baking color on the side surface of the bread.

Means for Solving the Problems In order to solve the above problems, the present invention provides a baking chamber in which both ends of a substantially U-shaped heater are attached to one side wall of the inside, and a baking material installed in the baking chamber. , A kneading means for kneading the bread material in the baking case, a temperature detecting section for detecting the temperature of the baking case, and energizing the heater based on the detection result of the temperature detecting section. A controller for controlling each of the kneading, curing, fermentation, and firing steps, and at least a part of the heater is located between the side wall of the firing chamber and the side wall of the firing case, and the temperature A detection unit is provided between both ends of the heater and is provided on one side wall inside the firing chamber, and the winding pitch of the heater is configured to be coarser in a portion facing the temperature detection unit than in other portions. Is.

Operation According to the above configuration, both ends of the substantially U-shaped heater are attached to one side wall inside the firing chamber, and at least a part of the heater is positioned between the side wall of the firing chamber and the side wall of the firing case. And a temperature detecting portion is provided between both ends of the heater on one side wall inside the baking chamber, and the winding pitch of the heater is made coarser than the other portion facing the temperature detecting portion. With this configuration, the temperature of the portion of the heater facing the temperature detecting portion can be lowered and the temperature of the other portion of the heater can be increased conversely during firing. The whole temperature distribution can be made uniform. Further, since the temperature control during baking can be accurately performed without bringing the temperature detection unit close to the heater, it is possible to eliminate the conventional imbalance of the baking color on the side surface of the bread.
