Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a mochi making machine that generates steam using a steam tank with a built-in heater, steams glutinous rice in a hopper, and then automatically makes mochi in the same hopper. It is something.

BACKGROUND ART Conventionally, in this type of rice cake making machine, a lid 41 was generally simply placed on a hopper 42, as shown in FIG.

Problems to be Solved by the Invention In order to make chewy rice cakes, the steam and heat in the hopper 42 must be released when the glutinous rice in the hopper 42 is steamed and then added to the next batch. Since the lid 41 cannot be opened automatically, the lid must be opened manually after the glutinous rice has finished steaming, making it impossible to carry out the entire process from "steaming" to "simmering". During the process of making mochi, it became a tedious task.
Also, there was no suitable structure for automatically opening the lid when steaming started.

The present invention eliminates the above-mentioned conventional drawbacks,
To provide an easy-to-use rice cake making machine that can perform a series of operations from ``steaming'' to ``making'' without requiring any human operations.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a main body that includes a built-in electric motor and a steam tank, a hopper that engages with the steam tank via a sealing material, and a hopper that is driven by the electric motor inside the hopper. a steaming-up detection device that detects steaming in the hopper and forms an energizing circuit for the motor; a lid that covers the opening of the hopper and has a shaft portion; It is provided with a top frame that is freely pivoted, and a stop that opens the lid when the electric motor starts rotating, and has a lower end surface of the lid that comes into contact with a hopper on the opposite side of the shaft portion formed on the lid at one or more places. A notch is provided in the lid to ensure that the lid can be opened by the above-mentioned tip.

Function: With the above configuration, the process from "steaming" to "cooking" can be carried out in a series without any human intervention, and the movement of the lid when opening is ensured.

The push-up bar 27 is supported by a support fitting 30 via a bearing 29. A fitting piece 31 is attached to the lower part of the push-up bar 27,
It is adapted to engage with the hook piece 32. When the fitting piece 31 engages with the hook piece 32, upward movement of the push-up bar 27 is restricted. The hook piece 32 is provided with a tight spring 33, and the tight spring 33 biases the hook piece 32 in a direction in which the fitting piece 31 and the hook piece 32 are engaged with each other. Further, a claw portion 32a is provided at the tip of the hook piece 32, and the tip portion 25a of the clutch spring 25 engages with the claw portion 32a. Further, a damper spring 34 is attached to the push-up bar 27 between the fitting piece 31 and the bearing 29, and prevents the push-up bar 27 from rising rapidly.

The support fitting 30 is attached to the ceiling frame 2 at the upper part and to the motor mounting base 12 at the lower part.

Next, the operation of the rice cake making machine will be explained. First, put a predetermined amount of water into the steam tank 11,
Put glutinous rice into hopper 3. Then, the shaft 5 of the lid 4 is fitted into the bearing part 6, and the lid 4 is closed. At this time, since the push button 8 is provided with a rib 8a that is raised at the center of the lid 4 and becomes lower toward the outer periphery in an R shape, the angle at which it contacts the support rod 26 is constant and the lid 4 can be held without getting caught. Can be closed smoothly. Then, when the push button 8 is pressed, the fitting piece 31
The hook pieces 32 are fitted and set, and the lid 4 is closed.

Next, when the switch is turned on manually, the heater 13 is energized, and after a predetermined time, steam is generated from the steam tank 11, and the glutinous rice is steamed in the hopper 3 through the steam hole 18. When the water in the steam tank 11 has completely evaporated, the temperature regulator 17 detects a sudden temperature rise in the steam tank 11 and turns off the power to the heater 13. At the same time, the temperature regulator 17 is switched, the electric motor 21 is energized, the small pulley 23 and the large pulley 20 rotate,
The clutch spring 25 attached to the large pulley also rotates. And the tip 25a of the clutch spring 25
is caught on the claw portion 32a of the hook piece 32, and the hook piece 32 and the fitting piece 31 are disengaged from each other. Then, the compression spring 28 expands and the support rod 26 and push-up bar 27
Push up to open the lid 4 via the push button 8. At this time, when the steaming is completed, steam may condense on the contact area between the hopper 3 and the lid 4 and become water, resulting in a sealed state between the hopper 3 and the lid 4, and the compression spring 28 Stretching force is about 2 kg (however, the lid 4
There were cases where the lid 4 did not open when the support rod 26 was 20 mm away from the shaft support and the weight of the lid 4 was approximately 100 g. By forming a notch 4a in the lower end of the lid 4, the lid 4 is reliably opened without being sealed even if steam condenses. In this way, the lid 4 is opened and the blade 9 is released while the heat and steam inside the hopper 3 is released.
is driven by the electric motor 21, and the rice cake is cooked several minutes later.

As described above, the process from "steaming" to "cooking" can be carried out in a series without requiring any human operations during the process, and the lid 4 can be opened reliably. In this case, the notch 4a is desirably about 2 to 7 mm from the contact surface with the hopper 3, since there is no seal due to steam condensation and steam escapes from the notch 4a.

Effects of the Invention As is clear from the description of the embodiments above, the present invention includes a lid that covers the opening of the hopper and is provided with a shaft, and a shaft that biases the lid in the opening direction when the electric motor that makes the rice cake rotates. By cutting out the lower end surface of the lid that contacts the hopper on the side substantially opposite to the shaft portion of the lid, it is possible to reliably perform the steps from "steaming" to "sticking" in a continuous manner.
