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, as shown in FIG. 3, conventional rice cake making machines generally only have a lid 32 placed on a hopper 31 provided on a main body 34 having a steam tank 33.

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

The present invention eliminates the above-mentioned conventional drawbacks,
The process from ``steaming'' to ``kneading'' can be carried out without any human intervention.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a lid that covers the opening of the hopper and is partially supported by a ceiling frame that covers the upper part of the main body, and a lid that is disengaged from the lid. a lid opening/closing device that opens the lid by pushing up the vicinity of the support portion of the lid when the lid is opened; a transmission portion that transmits the rotation of the motor to the lid opening/closing device; and 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 in the hopper, and the lid opening/closing device is disengaged by rotation of the motor via the transmission unit, and the lid is closed. The structure is such that the

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 lid is left open for ``kneading,'' steam and heat escape, allowing the creation of delicious, chewy rice cakes.

9, engagement pulley 21, connection shaft 22, push-up bar 2
3. Compression spring 24, hook piece 25, hook spring 2
This is a support for a lid opening/closing device consisting of 6 parts. Support 2
7 is attached to the ceiling frame 2 at the upper part and to the motor mount 10 at the lower part.

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, and the push-up bar 2
3 is raised by the compression spring 24 to open the lid 4,
Furthermore, the blade 7 also starts kneading, and a few minutes later, the rice cake is completed.

As described above, it is possible to perform the steps from "steaming" to "kneading" in a series without requiring any human operations during the process, and the steaming state in the hopper 3 is detected by the steaming state detection device consisting of the temperature controller 16. Since the lid 4 is opened at the same time as the detection of , steam and heat can quickly escape from the sufficiently steamed glutinous rice, making it possible to make delicious and chewy rice cakes.

In one embodiment of the present invention, the lid opening/closing device has been described as having an engaging/disengaging configuration using the rotation of the motor 8, but this lid opening/closing device can be modified as appropriate, such as by being directly pushed up by an electric plunger or engaging/disengaging by an electric magnet. However, the effect can still be obtained.

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.

Furthermore, in the explanation, the lid 4 is pivoted near the top frame 2 passing through the push-up rod 23 and is attached so as to be openable and closable.
Needless to say, the configuration is not limited to this.

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 the hopper and is partially supported by a ceiling frame that covers the upper part of the main body, and A lid opening/closing device that opens the lid by pushing up the vicinity of the support portion of the lid with a push-up rod, a transmission portion that transmits the rotation of a motor to the lid opening/closing device, and a steaming detection device that detects steaming in the hopper. a control unit that drives the motor when the steaming-up detection device detects steaming in the hopper, and engages the lid opening/closing device by rotation of the motor via the transmission unit. With this configuration, the controller drives the motor to operate the lid opening/closing device and open the lid at the same time as the steaming detection device detects steaming in the hopper. Steam and heat are released from the glutinous rice, and the blades rotate to "steam" the rice.
The process from ``kneading'' to ``kneading'' can be carried out in a series without the need for human operations such as opening the lid in between, and the operability is further improved. Moreover, by opening the lid and performing ``kneading,'' steam and heat are released, which has great effects, such as making delicious and chewy rice cakes.
