Description

  The present invention relates to a kneading machine that steams sticky rice with steam generated from a boiler and then raises the sticky rice to make rice cake.

  2. Description of the Related Art Conventionally, a tacking machine that introduces steam from above a hopper and causes the steam to flow down from above is provided with a lid that covers the hopper that contains the rice at the top of the main body. This lid is attached to the upper part of the hopper so as to prevent dust from entering inside during storage and use, and in the process of steaming the glutinous rice, the steam spreads in the hopper.

  However, in a tacking machine that introduces steam from the top of the hopper and flows down from the top, the lid that is simply placed on the top of the hopper is easy to open and close, while the lid is closed in the steaming process. If it is incomplete, the steam introduced from the boiler through the gap between the lid and the hopper escapes to the outside as it is and does not reach the bottom layer of the hopper, resulting in a problem that the steam does not steam well.

In addition, the lid of the tacking machine that introduces steam from the top of the hopper and flows down the steam from the top has a weight because it has a steam introduction pipe inside, so if the capacity of the tacking machine increases As the lid becomes larger, it is necessary to take care not to slide the hand while requiring a force for the opening / closing operation.

Then, the protrusion 47 pushes the wall of the recess 48 to retract the hook member 38 against the spring force of the first coil spring 43, and at the same time removes the hook 39 from the engagement hole 41. The projecting piece 45 that has been in contact with the projection 46 moves rearward as the hook member 38 moves backward, is dropped to the back side of the projection 46 by the bias of the second coil spring 44, and is attached to the first coil spring 43. It is pressed against the back surface of the protrusion 46 by the force, and the movement of the front, rear, up, down, left and right is restricted. Due to this restriction, the hook 39 is held in the disengaged state, and the hook operating lever 27 is also fixed in the raised state. When the hook 39 is removed from the engagement hole 41, the lid is opened by lifting the hook operating lever 27 while holding the finger.

  When closing the lid body 4 in the opened state, the lid body 4 is slowly lowered by placing a finger on the finger hooking portion 49 of the hook operating lever 27 in the raised state. When the lid is closed, the hook 39 exposed from the lid cover 30 comes into contact with the upper edge of the trunk and is pushed into the lid body 4. Then, the hook member 38 moves upward, the engagement of the protrusion 45 is released from the protrusion 46, and the restriction on the movement of the hook member 38 is released. The hook member 38 is urged forward by the spring force of the first coil spring 43, the hook 39 is inserted into the engagement hole 41, and the hook operation lever 27 returns to a position flush with the upper surface of the upper lid 29.
