Bread making machine and its controlling method

Abstract

A bread maker including a pair of kneading drums inside an oven compartment, to which are attached opposite ends of a mixing bag containing bread ingredients, the kneading drums reversing rotary direction periodically; a bar code scanner to read a bar code on the mixing bag ; a drum driving part rotating the kneading drums in clockwise and counterclockwise directions; a bar code reading checking part sensing whether the bar code scanner is reading the bar code; and a controller determining whether the bar code scanner is reading the bar code based upon a sensed signal output from the bar code reading checking part, and controlling the drum driving part to rotate the kneading drums at a bar code reading speed while the bar code scanner reads the bar code, and at a faster dough kneading speed when the bar code scanner has completely read the bar code.

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Application No. 2002-42594 filed with the Korean Intellectual Property Office on July 19, 2002, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a bread maker and a method of controlling the bread maker. Background technique [0004] In general, bread making is so complex that it is difficult for the average person to make satisfactory bread by hand at home. That is, making bread includes a number of steps: mixing ingredients such as flour, sugar, yeast, etc. to form dough; kneading the dough, allowing the dough to rise; baking the dough; and the like. [0005] Therefore, various bread makers have been developed to allow users to easily make bread. Bread makers automatically perform many of the above steps and provide the finished bread to the user. [0006] For example, a bread maker disclosed in Korean...

Problems solved by technology

[0010] However, in conventional bread makers, when the barcode scanner reads the barcode by rotating the upper kneading drum, the upper kneading drum may be jammed by the barcode of the mixing bag

Also, when the mixing bag is wrapped around the kneading drum, the kneading drum can become clogged with foreign matter, so operating the breadmaker can become dangerous and components inside can be damaged
