Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic bread maker that automatically bakes bread.

BACKGROUND TECHNOLOGY Automatic bread making machines currently on the market perform everything from kneading to baking under the same conditions, regardless of the amount of input ingredients.

Problems to be Solved by the Invention However, the kneading time will naturally change depending on whether the amount of ingredients added is small or large, and the speed at which heat is transferred to the inside of the dough will also change. When there were few ingredients, there was a risk of over-kneading, over-fermenting, or over-baking, and conversely, when there were too many ingredients, there was a risk of under-kneading, under-fermenting, or under-baking.

The present invention solves these problems and provides an automatic bread maker that detects the amount of input ingredients and can always make good bread regardless of the amount of ingredients.

Means for Solving the Problems In order to achieve the above object, the automatic bread maker of the present invention detects the amount of input ingredients with an amount detection means and makes bread based on that information and temperature information. It is designed to execute the process.

With this structure, even if the flea of input ingredients changes, it is possible to always make good bread by changing the bread making process time, control temperature, etc. to the optimal conditions based on the amount information and temperature information. It is possible.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, 1 is the main body of the automatic bread maker, 2 is a chassis provided inside the main body 1, 3 is a motor installed on this chassis 2, and 4 is a motor cooling fan provided at one end of the shaft 5 of the motor 3. , 6 is a small pulley attached to the other end of the shaft 5; 7 is a fan guide provided around the motor cooling fan 4; 8 is a large pulley attached to one end of the shaft 10 supported by a bearing 9; 11 is a large pulley attached to one end of the shaft 10 supported by a bearing 9; Connector attached to the other end of the shaft 10, 12 is a small pulley 6
13 is a container fixing guide provided on the chassis 2, 14 is a kneading container installed guided by the container fixing guide 13, and 15 is an inner bottom of the kneading container 14. 17 is a bearing that supported the shaft 25; 18 is a connector on the kneading container side that is attached to the other end of the shaft 16 and is detachably connected to the connector 11; , 19 is a heater provided around the lower part of the kneading container 14, 20 is a baking chamber that accommodates the heater 19 and to which the kneading container 14 is detachably attached, 21 is a container lid of the main body 1, and 22 is a heater provided in the center of the container lid 21. The yeast container provided, 23 is the lid of the yeast container 22, 2
4 is a charging lid thereof; 25 is a temperature detection unit that comes into contact with the side wall of the kneading container 14 to detect the internal material temperature when the kneading container 14 is installed in the baking chamber 20; 26 is a control device for the automatic bread making machine; Reference numeral 27 denotes an amount detection means for detecting the amount of material put into the kneading container 14.

As shown in FIG. 2, the control device 26 includes a condition setting section 28 that can be operated from the outside, and a temperature detection section 25. The motor 3 is connected to the amount detecting means 27 and the condition setting section 28.
．． It has a control section 29 that controls the heater 19, and determines control conditions for the motor 3, heater 19, etc. based on input information from each section. Further, the amount detection means 27
Detects the input current or torque of the motor 3 during the kneading process.

Next, the operation of the above embodiment will be explained. A kneading container 14 equipped with a kneading blade 15 and containing materials other than yeast such as flour and water is set in a baking chamber 20, a container lid 21 is closed, and a predetermined amount of yeast is put into a yeast container 22.

In this state, the completion time of the bread is input from the condition setting section 28 and the process is started. Then, at a predetermined time, the motor 3 starts operating, the small pulley 6 rotates, and the large pulley 8 and connector 11 rotate via the belt 12. The connector 11 transmits drive to the connector 18 to rotate the kneading blades 15 in the kneading container 14 to knead the material. At this time, the input current torque flowing to the motor 3 changes depending on the amount of material introduced, the amount of material introduced is detected based on the magnitude, and the control conditions of the motor 3 and heater 19 are optimized based on this information. conditions. For example, if the amount of input is large, the time for kneading, fermentation, baking, etc. may be lengthened, the control temperature may be increased, and
Control is performed to increase the capacity of the heater 3. Furthermore, when a predetermined time comes, a drive device (not shown) inside the container lid 21 is energized, the charging lid 24 is opened, and the yeast contained in the yeast container 22 is kneaded into the container 14.
Put it inside. After the yeast put into the kneading container 14 is kneaded with other materials for a predetermined time, the temperature of the kneading container 14 is controlled by the heater 19 while inputting information from the temperature detection section 25 under the control of the process IQ of the controller 26. Each step of primary fermentation, secondary fermentation, degassing, molding fermentation, and baking is performed automatically while making adjustments, and the bread is baked at the set time. It should be noted that, as the amount detecting means 27, the one that detects the input terminal among the above-mentioned embodiments is the most practical in its configuration, but a torque detecting method can also be easily implemented. In addition to these, there may also be devices that detect the weight of the material or devices that detect the bulk of the material.

Effects of the Invention As is clear from the embodiments described above, the automatic bread maker of the present invention detects the amount of input material at the start of kneading as the amount of load applied to the motor, and the subsequent control conditions are determined based on the input amount. By controlling heaters, motors, etc. under optimal control conditions, regardless of the amount of material input,
This has the effect of always making good bread.
