Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a rice cake making machine that steams glutinous rice in a hopper and then kneads it to make rice cake.

Conventional technology Generally speaking, the temperature at which a good rice cake rises is around 65°C to 70°C, and in this type of electric rice cake making machine, the lid of the hopper is opened as soon as the glutinous rice is steamed in the hopper. It was necessary to release excess heat and steam inside the hopper.

However, conventional rice cake making machines generally only have a lid 31 placed on a hopper 32 of a main body 33, as shown in FIG.

Problems to be Solved by the Invention In other words, in the conventional mochi making machine, a buzzer notifies the user that the glutinous rice in the hopper 32 has finished steaming, and the user quickly opens the lid 31 and operates the changeover switch to start the next kneading process. It was very inconvenient to use.

The present invention eliminates the above-mentioned conventional drawbacks,
To provide a mochi pounding machine that can perform a series of operations from "steaming" to "kneading" without requiring any human operations.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides an original technology that includes a lid that covers the opening of the hopper, and a bearing that houses the hopper and pivotally supports the lid so that the lid can be opened and closed. a lid opening/closing device that pushes up the lid with a push-up rod to open the lid when the engagement is released; a transmission section that transmits the rotation of the motor to the lid opening/closing device; A rotating blade, a lid opening/closing device that opens the lid using the motor, a steaming-up detection device that detects steaming in the hopper, and a control unit that drives the motor when the steaming-up detection device detects steaming. The rotation of the motor via the transmission section disengages the lid opening/closing device and opens the lid, and also moves the push-up bar of the lid opening/closing device toward the center side relative to the bearing section of the top frame. and is configured to be close to the bearing portion.

Effect With the above configuration, when the steaming detection device detects steaming in the hopper, the motor and lid opening/closing device are activated, and the rice cake is kneaded while releasing steam and heat from the glutinous rice. It is possible to carry out a series of operations without requiring the operator to open the lid during the process of "kneading". Moreover, since the push-up bar of the lid opening/closing device is located closer to the center and closer to the bearing part of the top frame, even when the lid is open, the push-up bar only slightly protrudes from the top frame. It does not get in the way when putting rice cakes in or taking them out. Furthermore, when closing the lid, by pressing the side away from the bearing part, the lid can be closed with a small force due to the lever principle.

Reference numeral 35 denotes a control unit that rotates the motor 8 when the temperature regulator 16 detects a sudden temperature rise in the hopper 3.

Next, the operation of the rice cake making machine will be explained.

First, a predetermined amount of water is poured into the steam tank 10, glutinous rice is put into the hopper 3, and the lid 4 is set to complete preparations. At this time, by setting the lid 4, the push-up bar 23 descends against the compression spring 24, and the hook piece 25 is engaged with the engagement pulley 21. When the switch is turned on manually, the heater 12 is energized, and after a predetermined period of time, water vapor is generated from the steam tank 10 and the glutinous rice is steamed in the hopper 3 through the steam hole 17.

When the water in the steam tank 10 is completely evaporated, the temperature regulator 16 detects a sudden temperature rise in the steam tank 10, and the control unit 35 turns off the power to the heater 12, and at the same time the motor 8 starts rotating. Then, the engagement pulley 21 starts rotating from the main pulley 18 via the belt 20 and the slave pulley 19. Then, the claw 21a disengages the hook piece 25, the push-up bar 23 is raised by the compression spring 24 to open the lid 4, and the blades 7 also start kneading, and a few minutes later, the rice cake is completed.

As described above, the process from "steaming" to "kneading" can be carried out in a series without any human intervention. By arranging the push-up rod 23 closer to the center than the portion 6 and closer to the bearing portion 6, the stroke of the push-up rod 23 when opening the lid 4 can be made smaller. Therefore, even when the lid 4 is open, the push-up rod 23 does not protrude from the top frame 2 very much.
Don't be nervous when adding glutinous rice or removing mochi. Further, when closing the lid 4, by pushing the side away from the bearing portion 13, the lid 4 can be closed with a small force based on the lever principle.

In addition, in the above embodiment, the engagement and disengagement configuration was explained using the rotation of the motor 8 as the lid opening/closing device.
This lid opening/closing device can be sufficiently effective even if the design is changed as appropriate, such as engagement/disengagement using an electric magnet.

In addition, a temperature controller 16 is used as a steaming detection device.
As described above, this steaming-up detection device may be configured to use a timer or the like to switch the contact point after the time has elapsed for the glutinous rice in the hopper 3 to be sufficiently steamed.

Effects of the Invention As is clear from the description of the embodiments above, the present invention provides a lid that covers the opening of a hopper, a ceiling frame that houses the hopper and is provided with a bearing that pivotally supports the lid so that it can be opened and closed. a lid opening/closing device that pushes up the lid with a push-up rod to open the lid when the lid is released; a transmission section that transmits rotation of the motor to the lid opening/closing device;
The device includes a steaming-up detection device that detects steaming-up, and a control unit that drives a motor by the steaming-up detection device, and the lid opening/closing device is disengaged by rotation of the motor via the transmission unit to open the lid. At the same time, by placing the push-up bar of the lid opening/closing device closer to the center and closer to the bearing portion of the top frame, when the steaming-up detection device detects steaming in the hopper, the motor and lid opening/closing are activated. The device operates and kneads the mochi while releasing steam and heat from the glutinous rice, making it possible to perform a series of operations from ``steaming'' to ``kneading'' without requiring any human intervention, such as opening the lid. This will further improve the operability. Moreover, since the push-up bar of the lid opening/closing device is located closer to the center and closer to the bearing part of the top frame, even when the lid is open, the push-up bar only slightly protrudes from the top frame. The lid opening/closing device does not get stuck when putting in rice cakes or taking out rice cakes, and the lid can be closed smoothly, which is very effective.
