Problems solved by technology

[0011] However, during the intermittent driving of the motor, depending on the performance of the motor or the position of the bread dough, there may be excessive exhaust gas that causes damage to the bread dough, or insufficient exhaust gas that cannot be discharged smoothly.

Embodiment approach 1

[0033] figure 1 It is a partially cutaway sectional view showing a schematic structure of automatic bread maker 1 according to Embodiment 1 disclosed herein. The automatic bread maker 1 has an operation unit 2 , a container 3 , a baking chamber 4 , a stirring blade 5 , a rotating shaft 6 , pulleys 7 and 8 , a belt 9 , a motor 10 , and a driving unit 20 .

[0034] The operation part 2 is provided on the upper part of the main body of the automatic bread maker 1 . The operation unit 2 is provided with a plurality of operation keys for performing operations such as start / stop of bread making, and a display unit for displaying operation contents. The display unit also displays progress status, scheduled end time, and the like. The plurality of operation keys may include operation keys for inputting the quantity of bread ingredients.

[0035] Put bread ingredients into container 3. The container 3 is housed in the baking chamber 4 . A heater (not shown) is arranged in the baki...

Embodiment approach 2

[0106] Hereinafter, Embodiment 2 of the automatic breadmaker disclosed here is demonstrated.

[0107] In the initial stage of the kneading process, the bread ingredients are not sufficiently kneaded. Therefore, in the initial stage of the stirring process, the stirring blade 5 is rotated at a relatively low rotational speed (for example, 60 rpm) to suppress scattering of the bread ingredients.

[0108] When a predetermined time elapses in the kneading step, the kneading of the bread dough proceeds to a certain extent. At this point, the rotation speed of the stirring blade 5 is increased (for example, 250 rpm).

[0109] When the rotational speed of the stirring blade 5 is increased, the stirring blade 5 rotates while the bread dough sticks to the stirring blade 5 , so-called idling of the stirring blade 5 may occur. When the idling of the kneading blade 5 occurs, the bread dough cannot be kneaded sufficiently.

Abstract

Provided is an automatic bread maker, comprising a container, stirring blades, a motor, a pulse output part, an inverter part and a control part. Bread stuff is put into the container. The stirring blades are disposed in the container in a rotatable manner. The motor enables the stirring blades to rotate. The pulse output part outputs a pulse signal based on the rotation angle of the motor. The inverter part drives the motor. The control part controls the inverter part based on the pulse. In an air exhausting process, the control part calculates the rotating speed of a motor based on the pulsesignal, and controls the inverter part so that the rotating speed can be the target rotating speed. The control part calculates the rotating speed of the motor based on the pulse signal, and controlsthe inverter part so that the rotating angle can be the target rotating angle. In the air exhausting process, the damage of bread dough can be prevented, and air exhaust can be stably conducted.

Description

technical field [0001] The disclosure herein relates to automatic bread makers used primarily in ordinary households. Background technique [0002] In an automatic home-use breadmaker, bread is made by putting ingredients into containers that serve as baking molds. Usually, such an automatic bread maker makes bread by sequentially performing a stirring process, a primary fermentation process, an exhaust process, a secondary fermentation process, and a baking process. [0003] The degassing process is a process for degassing the gas present in the fermented bread dough. While the bread dough is shredded by the rotating mixing blades during the degassing process, the bread hardly expands during the baking process. [0004] Conventional techniques for solving this problem include an automatic breadmaker that has a container for putting raw materials and a stirring blade that rotates in the container centering on a vertical rotation axis. The mechanism is to stir the bread in...
