Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic bread maker that can knead flour and the like and make bread at home.

(Prior technology) Generally, when making bread, equipment such as a kneading machine, a fermentation machine, a rolling pin, and an oven are used, but it is extremely difficult to control the temperature and time. It required considerable skill to make fresh bread. In order to solve this problem, an automatic bread maker has been proposed that has a kneading function, a fermentation function, and an oven function in a single product. In such automatic bread making machines, the kneading container, which is used to mix and ferment ingredients and serve as a bread baking mold, plays an important role. There are many. By the way, since the temperature of the kneading container becomes high, it is not possible to use a switch directly, so the switch is operated via a lever. As methods for supporting such a lever, there are a cantilever type in which one end is fixed and the point of action and the switch operating point are in the same direction, and a rotary type in which the point of action and the point of action are in opposite directions.

(Problems to be Solved by the Invention) The cantilever type of kneading container detection method in such conventional motion bread making machines has a problem in that the stroke of the tip becomes large, and the rotary type has a problem in that the rotating shaft is supported. The method involves welding and fitting the shaft to the lever, or passing the shaft through a hole in the lever and fixing both ends of the shaft with separate members, which poses the problem of increased assembly man-hours and costs. It was hot.

(Means for Solving the Problems) Therefore, the present invention provides a hole provided in the intermediate part of a switch lever whose one end is pushed down at the lower end of the kneading container and which operates the switch at the other end, and a hole provided in the hanging piece of the chassis. One side of the switch lever shaft to be inserted into the hole is extended and bent to form an L-shape, the extended bent part of the lever shaft is inserted into the notch provided in the chassis, and the inside of this notch is inserted. A fixing member for fixing the position of the switch lever shaft extension bent portion is attached to the chassis.

(Function) Insert the switch lever shaft into the hole in the switch lever and the hole in the hanging piece of the chassis, insert the extended bent part into the notch in the chassis, and extend and bend the switch lever shaft inserted into the notch. Since the position of the switch lever is fixed by a fixing member attached to the chassis, the switch lever can be easily installed and assembled, and the number of assembly steps is reduced.

A cylindrical guide 43 is fixed to a heat shield plate 45 that covers the periphery of the firing container 44 and to the bottom of the firing container 44 so as to surround the connector 38 . A heater 48 is fixed to the wall of the firing container 44 with a stopper 47 via an insulator, and a container fixing spring 4
9 and an elastically supported temperature sensing section 50 are fixed. Further, the upper part of the firing container 44 is fixed to the main body upper frame 58 by a fixing member 57. The main body 30 is fixed to the main body upper frame 58 and also to the chassis 31. Reference numeral 55 denotes a kneading container housed in the firing container 44, with a handle 56 provided at the top and a cylindrical guide 43 at the bottom.

The large pulley 37 and the connector 38 rotate via the belt 39. The rotation of the connector 38 is directly transmitted to the container connector 52, and the kneading blades 53 in the kneading container 55 are rotated to knead the material. Then, when a predetermined time comes, the drive device 59 inside the lid 68 is energized to drive the transmission plate 61, move the rotating shaft 64, open the opening/closing plate 63, and release the yeast contained in the yeast container 65. Kneading container 5
Insert within 5. After the yeast put into the kneading container 55 is kneaded with other materials for a predetermined time, the temperature of the kneading container 55 is adjusted by the heater 48 while inputting information from the temperature detection section 50 based on the process control of the control device 71. The bread is baked at the set time by automatically performing the primary fermentation, degassing, molding fermentation, and baking steps while adjusting the temperature.
