Abstract

PURPOSE: To provide an automatic bread baker in which jam can be made without discoloration or burn by reducing the difference in temp. between upper and lower parts in a vessel, equally applying heat, sufficiently stewing the jam and rapidly cooling it. CONSTITUTION: Concerning this automatic bread baker, when a jam course is selected, the temperature is almost set at 70 deg.C in a preheating process, the electrification rate of a heater 18 is almost set to 45%, and heating is slowly performed at the comparatively low temperature so that the temperature in a vessel 6 can uniformly be increased. In a stewing process, the temperature is almost set at 100 deg.C and the electrification rate is almost increased to 67% so that the calorific amount can be increased at a low temperature and the jam can be sufficiently stewed at the uniform temperature. In an air blowing process, a fan motor 16 is operated while turning on a main motor 11 and stirring air so that cold air can be sent into a heating chamber 5, the materials of jam in the vessel 6 can rapidly and uniformly be cooled and the uniform jam can be made.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic bread maker having a stirring and heating function and a jam course in addition to a bread making course.

[0002]

2. Description of the Related Art A conventional automatic bread maker having a jam course is only a convection type, and is heated by an oven in the preheating and simmering steps and is cooled by a fan without being heated in the blowing step. There is. FIG. 6 shows the relationship between the time during operation and the temperature of the container, and FIG. 7 shows a control configuration table during operation. On the other hand, in the oven-type automatic bread maker, the temperature distribution of the container was poor, and there was a problem that the upper surface of the jam was discolored or scorched.

As a cooking machine capable of making jams at home, for example, as shown in Japanese Patent Laid-Open No. 62-32928, a kneading brush provided in a container placed on a heater is put through a speed reducing mechanism. Rotate it by the main motor,
While stirring at a stirring speed suitable for the type of cooking, an automatic jam is prepared by heating the material uniformly, or as a jam-manufacturing-dedicated machine, for example, as shown in Japanese Utility Model Publication No. 5-38697, intermittently in a container. Rotatable and crushes jam material
There is a rotary blade that mixes and stirs, and even coarse jammed materials such as fruits can automatically make jams by crushing, mixing, stirring and heating without cutting them into thin pieces in the previous work. Neither has a baking function.

[0004]

In the conventional automatic bread maker described above, when the convection method is controlled by the oven method, the temperature distribution of heat above and below the container is poor as shown in FIG. Therefore, a temperature difference occurs in the container, a temperature difference between the upper space temperature and the bottom portion is large, and there is a possibility that defects such as discoloration only at the top of the jam or burning depending on conditions may occur.

The present invention equalizes the temperature distribution of the container,
An object of the present invention is to reduce the temperature difference between the upper side and the lower side of the container so that heat can be evenly applied to the jam so that the jam can be cooled quickly.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is a container that is detachably mounted in a heating chamber and is attached to the outside of the container in the heating chamber. An automatic bread maker that has a heater, a main motor and a fan motor mounted outside the heating chamber, and a control device that controls the main motor, fan motor, heater, etc., and automatically performs food processing such as bread making. In the machine, a jam course is provided as a program of the control device,
In the preheating process when the controller selects the jam course, the set temperature is set to about 70 ° C., the energization rate of the heater is set to about 45%, and the container is heated slowly at a relatively low temperature, Temperature is raised uniformly, and in the simmering process, the set temperature is set to about 100 ° C., and the duty ratio is raised to about 67% to increase the heating amount at a low temperature so that the temperature becomes uniform. In the blowing process, the fan motor is operated while the main motor is rotating to stir the material of the jam to cool the air into the heating chamber and quickly and evenly cool the inside of the container. While trying to make jam.

[0007]

With this configuration, the temperature rises slowly during preheating, the difference in temperature between the top and bottom of the container is reduced, and in the simmering process, although the temperature is low, there is a large amount of heating. , The heat applied to the jam is evenly distributed, and the jam is sufficiently cooked, and the jam is cooled quickly and uniformly in the blowing process, so that the jam can be made without discoloration or charring.
