[0008]
In addition to the drive motor 8, a blower 12 including a blower fan 10, a fan motor 11, and the like is housed in the support frame 5 a, and air can be introduced from an air inlet 13 provided at an appropriate position of the support frame 5 a. It is configured. The end of the air duct 14 connected to the blower 12 is fitted to the end of the hollow support shaft 4. The support shaft 4 is rotatably provided, whereas the end of the duct 14 is fixed, and a seal is provided to ensure airtightness with the inner surface of the support shaft 2.
[0009]
In the fitting portion between the support shaft portion 4 and the support frame 5b, the exhaust duct 17 is communicated with the inside of the support shaft portion 4 so that the air from the blower is exhausted through the space in the upper and lower hooks. It is detachably provided inside the frame 5b. Further, the support shaft portion 3 constitutes a lower hook ventilation mechanism comprising a blower pipe, an exhaust port and the like leading to the blower so as to be blown to the outer periphery of the inner hook of the lower hook 2 formed on the double wall. That is, one end of the blower pipe 19 is connected to the support shaft portion 3 of the support frame 5a. The air pipe 19 end is connected and fixed to an appropriate position of the outer hook portion of the lower hook 2 so that air can be blown to the outer circumference of the inner hook. The wind of the blower 12 is branched and supplied to the cooked rice cooling air supplied to the inside of the kettle and the ventilation cooling air of the lower kettle 2, and the ventilation of the lower kettle 2 enters from the tangent direction of the kettle and is spirally ventilated at the lower end. The exhaust port 20 is exhausted.
[0010]
Reference numeral 21 denotes a connection fitting for connecting the upper hook 1 and the lower hook 2. Further, although not shown in the figure, the lower hook 2 is appropriately provided with a shaving bar in a cross state, which is effective for loosening and the like when the rice is stirred and mixed by rotation.
[0011]
In the above configuration, the rotation stop control of the hooks 1 and 2 and the operation control of the blower 12 are performed by the control unit 22. The control unit 22 receives operation signals from various switches arranged on the surface of the operation panel 23 and inputs sensor detection signals such as a reference stop position detection sensor and a discharge position detection sensor, which will be described later, while driving motors. 8 or a drive stop signal is output to the blower 11. The operation panel 23 is divided into a left half portion where operation switches are arranged and a right half portion where various settings are made, and consideration is given to facilitating operation and reducing erroneous operations. As the left half operation switch, in addition to the power switch 25, a start switch 26, an automatic operation switch 27, a sharpening switch 28, a manual switch 29, a repeat switch 30, and a 7-segment time display unit 31 are provided. Yes. In the right half, “Run”, “Maze” (pull rotation), “Murashi” (puff time after hook stop), “Intermittent” (pull rotation intermittent time), “Blow” (puff time) A mode selection switch 32 for setting each time, a setting switch 35 for setting an arbitrary course by a combination of the mode selection switch 32, a plus switch 33 and a minus switch 34 for increasing / decreasing the timer time, and setting input A group of course switches 36 for determining or calling a course is arranged. The control unit 22 has a built-in timer. In addition, an LED lamp 37 is disposed above each switch of the mode selection switch 32 so that the mode setting display and the currently executing mode can be displayed. These mode selection switch groups are combined with the timer switches 33 and 34, and (1) “Operation” switch sets the total operation time for one operation, and (2) “Maze” is the mixing operation time from the start of operation. Set. (3) “Murashi” sets an irregular time from the mixing work time, and (4) “Intermittent” sets an intermittent stop time until the end of operation. {Circle around (5)} “Blow” sets the time for starting air cooling. (6) “Cooling” includes various settings such as setting the cooling start time by blowing air to the outer pot, and the course can be set by combining these settings. An example is shown in FIG.
[0012]
The control unit 22 has the following functions. By turning on the automatic operation switch 27 and the start switch 26, automatic operation is executed based on the course previously selected by the course switch 36. When an automatic driving signal to be output is received, automatic driving is performed according to a preset course. The drive motor 8 is started, the hooks 1 and 2 are rotated for a predetermined time, and the blower 12 is started at the same time to start blowing. The control unit 22 has the following functions in stopping the shuttle rotation. The shuttle rotation stop signal is output when the predetermined time has elapsed, but the drive motor 8 does not stop immediately but receives the detection output of the reference stop position detection sensor 38 to stop the motor 8. Specifically, the upper hook 1 of the hooks 1 and 2 is stopped in a loosely inclined state slightly inclined toward the discharge position (FIG. 1 (A)). Further, when the release switch 28 is turned on in this stop mode, the drive motor 8 is started until the detection position of the discharge position detection sensor 39 is reached, and the hooks 1 and 2 are set at a steep angle with the lower hook 2 opening further downward (see FIG. 1 (b)). When it is desired to obtain a steeper angle from the detection position of the discharge position detection sensor 39, the release switch 28 is continuously turned on. That is, the lower hook 1 gradually rotates according to the on time of the shaving switch 28 and stops when the shaving switch 28 is turned off. In addition, when the cumulative on-time is exceeded (for example, 4 seconds), the rotation is returned to the standard position after approximately one rotation. Therefore, although it can be steep to maximum inclination angle on the time management of the accumulated, it can cost reduction be covered by the management of the time without providing each separate sensor to its maximum angular position.
[0013]
The reference stop position detection sensor 38 and the discharge position detection sensor 39 are provided on the outer periphery of the sprocket 7. That is, these sensors 38 and 39 are in the form of a reed switch, and are configured to output a detection signal by sensing a magnetic material (not shown) provided appropriately on the outer periphery of the sprocket 7. These detection sensors 38 and 39 are appropriately fixed to the machine frame by mounting plates 40 and 41, but the reference stop position detection sensor 38 has a gentle inclination angle with the open upper surface of the lower hook 3 slightly downward from the horizontal state. Thus, the discharge position detection sensor 39 is set to be slightly steeper than this. Further, the discharge position detection sensor 39 is formed with a long hole in the mounting plate 41 so that the angle of the sensor 39 fixing position can be adjusted appropriately along the outer periphery of the sprocket 7.
[0014]
The operation of the above example will be described.
The upper pot 1 of the pots 1 and 2 at the detection position of the reference position stop sensor 38 is removed, and a required amount of cooked rice and vinegar necessary for it are added. The upper hook 1 is attached, the inside is sealed, and the operation start switch 26 is turned on. The drive motor 8 starts and the shuttles 1 and 2 start rotating. The internal cooked rice is cut back and stirred by the rotation of the kettle. During this time, it will be mixed with vinegar. By the way, outside air is supplied into the hook by the operation of the blower 12. That is, the blower fan 10 is activated by the rotation of the fan motor 11 and air is introduced from the air suction port 13, reaches the inside of the pot via the blower duct 14 and the support shaft portion 3, and acts on the stirred rice. Can be cooled. During the stirring and mixing operation, the air is blown to the outer periphery of the inner hook of the lower pot 2 through the blow pipe 19 and the blow connecting pipe 21, and the lower pot 2 is air-cooled.
[0015]
When the driving time of the course set in advance by the amount of cooked rice or the quality of rice elapses, the drive motor 8 automatically stops rotating. In other words, control is performed to automatically stop at the position detected by the reference stop position detection sensor 38 ((A) position in FIG. 1). Next, the shaving take-off switch 28 is turned on so that the lower hook 2 stops at a position where it is easy to receive and take out the whole rice, for example, the lower hook 2 is steeply inclined toward the take-out operator side. By this operation, the lower hook 2 is stopped at the position detected by the discharge position detection sensor 39 ((b) in the figure). Note that the stop position by the discharge position detection sensor 39 can be arbitrarily set according to the height of the apparatus and the physique of the unloading operator because the sensor 39 mounting position can be adjusted within the range of angle (c).
[0016]
When the tilt angle is still necessary, the shredding switch 28 is turned on. During this ON time, the drive motor is activated and rotates to the switch 28 OFF, and a desired tilt angle can be obtained.
[0017]
When the operation for taking out the cooked rice from the inside of the lower pot 2 is finished, the shredder switch 28 is continuously turned on. For example, when the accumulated on-time becomes 4 seconds or more, the lower hook 2 stops by rotating approximately once to the position (the position (A) in FIG. 1) detected by the reference stop position detection sensor 38.
