Abstract

PURPOSE: To interrupt transmission to a baking case guide member of heat generated in a motor by providing a heat shielding member between the baking case guide member provided on the bottom part of a baking chamber for guiding a baking case at the time of mounting the baking case to the baking chamber and the motor installed at a position facing it. CONSTITUTION: The backing case guide member 44 for guiding the baking case 27 at the time of setting the baking case 27 into the baking chamber 25 is disposed so as to project inwards from the upper surface of an almost box- shaped upper angle 24 and the outer peripheral part is fixed to the inner bottom surface of the baking chamber 25. Thus, since the side of the upper angle 24 constituted of sheet metal is positioned between the motor 32 and the baking case guide member 44 and then the upper angle 24 achieves the role of the heat shielding member, the heat generated in the motor 32 is interrupted on the side face of the upper angle 24 before being transmitted to the baking case guide member 44 and the baking case guide member 44 is not temperature- raised by the heat of the motor 32.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention automatically performs a series of fermentation and baking steps by simply adding predetermined ingredients, so that freshly baked bread can be prepared at the desired time. This relates to bread making machines.

Conventional technology When baking bread at home, we generally use a kneading machine, a fermentation machine, a stretching rod, an oven, etc., but it is very difficult to control the temperature and time, so it is necessary to automate this to some extent. As a conventional technique for baking bread, various types of bread making machines have been devised that automatically bake bread simply by setting the baking time, an example of which is shown in FIG.

That is, in FIG. 2, 1 is a main body case, 2 is a chassis provided in the main body case 1, 3 is a motor, 4 is a heater, and 6 is a firing chamber whose outer periphery is covered with a heat insulating material 6. Motor 3. The heater 4° firing chamber 6 is connected to the chassis 2.
is fixed. A firing case 8 having a kneading blade 7 is detachably installed in the firing chamber 6, and the kneading blade 7 is moved by a pulley 9. Belt 10. It is rotated and driven while being decelerated via a pulley 11. Further, above the firing chamber 5, there is a lid body 1 having an inner lid 2 that can be opened and closed.
3 is provided. Furthermore, a temperature detector 14 for detecting the temperature of the firing case 8 and the motor 3. A control device 15 for controlling the heater 4 and the like, and an input device (not shown) for setting control conditions for the control device 15 are provided. With this structure, when bread ingredients are put into the baking case 8 and the baking time and other information are input through the input device, the motor 3 starts operating at a predetermined time and detects the temperature of the baking case 8. A kneading process is performed while the kneading process is performed, and when a predetermined temperature or a predetermined time is reached, the motor 3 is stopped and the fermentation process begins. In this fermentation process, the temperature is controlled by the heater 4 depending on the temperature of the baking case 8, and degassing is performed several times by the rotation of the motor 3. After a predetermined period of time, the heater 4 is energized. A firing process is performed, and the kun is baked at a desired time.

Problems to be Solved by the Invention In such a conventional bread making machine, the motor 3 is disposed on the side of the baking chamber 5, and the motor 3 moves the pulley 9.
Belt 10. Since the kneading blades 7 are rotationally driven through the pulley 11, there is a problem in that the size of the bread making machine itself becomes longer in the lateral direction and becomes larger.

Therefore, in consideration of this problem, when making the bread making machine itself more compact, installing the motor 3 below the baking chamber 6 can prevent the bread making machine itself from becoming longer in the horizontal direction. However, in this case, when the firing case 8 is installed in the firing chamber S, the firing case guide member 15 that guides the firing case 8 and the motor 3 face each other. The generated heat is transmitted to the firing case guide member 15, raising the temperature of the firing case guide member 15, and ultimately raising the temperature of the firing case 8 as well. Generally speaking, mixing of bread dough is stopped when the dough temperature reaches a certain temperature, but as mentioned above,
If the arrangement is such that the baking case 3 and the baking case guide member 16 face each other, the baking case 8 receives heat from the baking case guide member 15 even after kneading of the dough is stopped.
This heat causes the temperature of the bread dough in the baking case 8 to rise, resulting in a problem in which the quality of the bread deteriorates.

In view of these problems, it is an object of the present invention to provide a bread making machine that can reliably prevent the temperature of bread dough from rising due to the heat of the motor.

Means for Solving the Problems In order to solve the above problems, the present invention provides a baking chamber heated by a heating means, a baking case installed in the baking chamber and housing bread ingredients, and a baking case that is installed in the baking chamber and stores bread ingredients. A kneading means for kneading the bread ingredients in the case, a baking case guide member provided at the bottom of the baking chamber and guiding the baking case when the baking case is installed in the baking chamber, and the mixing means are driven. It also has a motor installed at a position facing the baking case guide member, and a control device that controls each process of kneading, fermentation, and fermentation,
A heat shielding member is provided between the motor and the firing case guide member.

Operation According to the above configuration, the firing case guide member which is provided at the bottom of the firing chamber and guides the firing case when the firing case is installed in the firing chamber, drives the kneading means once, and faces the firing case nide member. Since a heat shielding member is provided between the motor and the motor installed in the position where the firing case guide member As a result, the temperature of the baking case guide member does not rise, so the temperature of the dough in the baking case does not rise even after kneading of the dough is stopped, which is the case in the past.
