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 automatically makes rice cakes in the same hopper.

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

Problems to be Solved by the Invention By the way, in order to make chewy rice cakes, the steam in the hopper 42 must be released after the glutinous rice in the hopper 42 is steamed and the next time it is added. Since the lid 41 cannot be opened automatically, the lid 41 must be opened manually after the glutinous rice has finished steaming, making it impossible to perform the entire process from "steaming" to "simmering". , the work of making mochi had become a tedious task. Also lid 4
There was no suitable configuration to open 1.

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 manual operations.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a main body incorporating a motor and a steam tank, a hopper that engages with the steam tank, and a blade driven by the motor within the hopper. A steaming-up detection device that detects steaming in the hopper, a lid that covers the opening of the hopper and has a shaft in a part, a ceiling frame that houses the hopper and supports the front lid so that it can be freely opened and closed, and the lid. A push-up rod that biases the push-up rod in the opening direction, a hook piece that restricts the movement of the push-up rod, a one-way tightening clutch spring that releases the restriction on the movement of the push-up rod by the hook piece, and a motor that rotates. The clutch spring is rotatably supported on the pulley so that the operation of the clutch spring will not be adversely affected even if the blade is incorrectly rotated by hand or the like in the reverse direction. In other words, the direction in which the clutch spring is tightened is the direction of rotation when making rice cakes, and the rib formed on the pulley that transmits the rotation to the clutch spring is inclined so that the clutch spring will spin idly in the opposite direction due to misuse. .

Function With the above configuration, the process from "steaming" to "cooking" can be carried out in a series without requiring any manual operation during the process, and even if the lid is used incorrectly, the lid can be opened reliably. Furthermore, the first lid can always be set regardless of the position of the release means.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In Figures 1 to 8, 1 is the main body, 2
is a ceiling frame that covers the upper part of the main body 1, and is formed by covering the hopper 3 which serves both as a steamer and a rice cake making chamber. Reference numeral 4 denotes a lid which covers the opening of the hopper 3 in an openable and closable manner, and a part of the lid forms a shaft 5 and is fitted with a bearing portion 6 formed on the ceiling frame 2 via the shaft 5.

Further, a hole 7 is provided in the lid 4 near the shaft 5, and a push button 8 is slidably attached to the hole 7. Reference numeral 9 denotes a blade installed in the center of the bottom of the hopper 3, and is detachably attached to a rotating shaft 10 protruding from the main body 1. Reference numeral 11 denotes a steam tank that is fixed to the motor mounting base 12 to form a steam generation chamber.A heater 13 is attached to the outer bottom, and a seal 14 is attached to the center to prevent water and steam from entering the main body 1. It is being 15 is a hopper mounting plate attached to the outer bottom of the hopper 3, and a fitting step 11 provided at the upper end of the steam tank 11.
They are removably engaged in an airtight manner via a packing 16 provided at a. 17 is the steam tank 11
This is a thermosensitive temperature controller. Reference numeral 18 denotes a steam hole that is opened at the center of the bottom of the hopper 3 and also serves as a through hole for the rotating shaft 10.

19 is a chassis that supports the rotating shaft 10;
The chassis 19 is fixed to the motor mounting base 12. Further, a large pulley 20 is attached to the lower part of the rotating shaft 10, and is connected via a belt 24 to a small pulley 23 attached to a motor shaft 22 of a motor 21 fixed to a motor mount 12.
The large pulley 20 has a clutch spring 2 formed of a fitting part 25a, a large diameter part 25b, a hook piece operating arm 25c, and an operating arm 25d that receives rotation of the pulley.
5 is rotatably fitted into the boss portion 20a, and the large pulley 20 has an operating arm 25d of the clutch spring 25.
A triangular rib 20a whose leading surface is perpendicular to the direction of rotation for transmitting rotation to the clutch spring 25 is formed.
When the operating arm 25c is pushed in the opposite direction to the rotational direction of the large pulley 20, the large diameter portion 25b is wound tightly, and the tip of the operating arm 25c is bent into a substantially U-shape. Reference numeral 26 denotes a support rod that penetrates near the bearing portion 6 of the lid 4 provided on the top frame 2 and is in contact with the push button 8 .

27 is a push-up rod that is in contact with the support rod 26;
A compression spring 28 biases the lid 4 in the opening direction.
The push-up rod 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 rod 27 and is adapted to engage with a hook piece 32. When the push button 8 is pressed, the hook piece 32 rotates by the force of the hook spring 33 and engages with the upper end surface of the fitting piece 31, thereby restricting upward movement of the push-up rod 27.

Further, a claw portion 32a is provided at the tip of the hook piece 32, and the operating arm 25c of the clutch spring 25 engages with the claw portion 32a. Furthermore, push up rod 27
A damper spring 34 is attached between the fitting piece 31 and the bearing 29 to prevent the push-up rod from rising rapidly. The support fitting 30 has an upper portion fixed to the ceiling frame 2 and a lower portion fixed to the motor mounting base 12.

Next, the operation of the mochi pounding machine will be explained. First, a predetermined amount of water is poured into the steam tank 10, the hopper 3 is fitted, the blades are set, and then glutinous rice is poured. Then, the shaft 5 of the lid 4 is fitted into the bearing part 6 of the top frame 2, the lid 4 is closed, and the push button 8 is pressed. Then, the fitting piece 31 moves down to a position where it fits into the hook piece 32, and the hook piece 32 is urged by the tight spring 33 and tries to fit. At this time, clutch spring 2
If the operating arm 25c of the clutch spring 25 is in the position shown in FIG.
If the fitting part 32a with 5c slides and rotates in the rotation direction and is in the position shown in FIG.
The fitting piece 31 and the hook piece 32
are mated. Therefore, the clutch spring 2 of the present invention
5, the fitting piece 31 and the hook piece 32 can always be fitted together regardless of the position of the clutch spring 25, and the lid 4 can be kept in a closed state. Next, when the switch is manually turned on, the heater 13 is energized, 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 evaporates, steam tank 1
1 suddenly rises in temperature, the temperature regulator 17 detects this and cuts off the power to the heater 13. At the same time, the temperature regulator 17 switches, the motor 21 is energized, and the large When the pulley 20 rotates, the rotation is transmitted to the arm 25d of the clutch spring 25 by the triangular rib as shown in FIGS.
After the large-diameter portion 25b is tightly wound and comes into close contact with the boss 20a of the large pulley 20, the tight spring 33
The hook piece is rotated in the direction of the arrow against the urging force of , the fitting piece 31 is disengaged, the restriction on the push-up bar is released, and the lid 4 is opened via the support bar 26 by the force of the compression spring 28. The blades 9 are rotated by the drive of the motor 21 while releasing the heat and steam inside the hopper 3, and the rice cakes rise after a few minutes.

Moreover, even if the blade 9 is rotated in the opposite direction to the normal direction due to misuse, the rib that transmits the rotation of the large pulley 20 is not the triangular rib 20, as shown in FIGS. 7 and 8.
b, the hook piece 32 allows the operating arm 2 to
Even if 5c is restricted, the arm 25d rides on the slope and the rotation is not transmitted to the clutch spring. If both sides of the rib 20b are vertical, the small diameter portion 25a and the large diameter portion 25b of the clutch spring 25 will be permanently deformed to a large diameter, causing a problem (not shown) in which normal operation is impossible.

As described above, the process from "steaming" to "sticking" can be carried out in a series without any human intervention during the process, and the safety of the composition can be maintained even if it is misused. .

Effects of the Invention As is clear from the above description of the embodiments, the present invention includes a lid that covers the opening of the hopper, a push-up bar that biases the lid in the opening direction, and a hook piece that restricts the movement of the push-up bar. , is equipped with a one-way tightening type clutch spring that releases the restriction on the movement of the push-up rod by the hook piece, and a pulley that rotates by the drive of a motor, and the clutch spring is rotatably supported on the pulley, and By forming triangular ribs on the pulley that act in the tightening direction of the clutch spring and rotate the clutch spring in the opposite direction, it is possible to perform the steps from "steaming" to "tacking" in a series, and also to rotate the blades by hand in the opposite direction. This allows for a highly safe configuration in which the clutch spring does not operate abnormally even if the clutch spring is used incorrectly, such as when the clutch spring is accidentally rotated.
