Next, the operation of the above configuration will be described with reference to the time chart of FIG. 11 and the flowchart of FIG. When making sushi rice by mixing vinegar S with rice M, the cover 80 of the setting unit 55 is opened, and the conditions for mixing, steaming, and cooling are set according to the amount of rice M. For example, if the amount of rice M is 4 and steaming is not required, the setting switch 67 for mixing is set to "4" and the setting switch 70 for steaming is set to "0".
The setting switch 73 for cooling is set to "0" and set to "5".
Do the same for 3 and 2 boxes, then cover
Close 80.

The rotary container 3 is normally stopped at the loading position X with the opening 10 facing the upper right. Therefore, first, the rotating container
The lid 13 of 3 is removed, the required amount of cooked rice M is put into the rotary container 3, and after adding the required amount of vinegar S, the lid 13 is attached and the opening 10 of the rotary container 3 is opened. Block.

Next, the selection switches 63 to 65 are selected according to the amount of the rice M.
After pressing any of the above, the start switch 57 is pressed. For example, if the rice M is 4 boxes, the start switch 57 is pressed after pressing the 4 box selection switches 63. Then, the mixing control unit 82
Is activated, the mixing display lamp 61 is turned on, the drive motor 29 is activated, and the horizontal shaft 2 is driven in the direction indicated by the arrow a through the winding transmission mechanism 30, so that the rotary container 3 is integrated with the horizontal shaft 2. a
It rotates in the direction of the arrow (step S1). Then, each time the rotary container 3 makes one rotation and passes the loading position X, the cam plate 35
Thereby, the closing position detection switch 36 is operated (step 2), and the set number CT ₁ (for example, 4) set by the setting switch 67 for mixing of the setting portion 55 is sequentially subtracted (step S3).

When the rotary container 3 is rotated about the horizontal axis 2, the rice M in the rotary container 3 is rotated as shown in FIGS. 13 and 14.
As shown in (1), while moving, it moves relatively in the opposite direction, so that the vinegar S is mixed with the rice M. When the rotary container 3 rotates by the set number CT ₁ times and the predetermined mixing is completed, the mixing control unit 82 determines that the mixing is completed (step S
4) Then, the drive motor 29 is stopped to stop the rotary container 3 (step S5). At this time, the rotary container 3 is at the loading position X, and at the same time, the mixing display lamp 61 is turned off.

Next, the steaming control unit 83 operates and determines whether or not the steaming time is set (step S6). If the steaming time is set, the rotary container 3 is moved to the steaming position X while being stopped at the charging position X (step S7), and the vinegar S is permeated into the rice M. Then, when the steaming for the set time is completed (step S8), the cooling control unit 84 operates and shifts to cooling.

In this case, since the steaming setting switch is "00" and the steaming time is not set,
Immediately after the mixing is completed, the cooling control unit 84 works to shift to cooling. When the cooling controller 84 operates, the cooling fan motor 41 operates, the cooling fan 38 rotates, and the cooling indicator lamp
62 lights up. Then, when the cooling fan 38 rotates, external air is sucked from the outside of the support frame 8 through the air suction holes 44, and then the vertical feeding cylinder 39 and the connection box 40 pass through the tubular horizontal axis 2 and into the rotary container 3. Supply cooling air (step S9),
Start cooling the rice M in the rotating container 3.

At the start of this cooling, the rotary container 3 is stopped at the charging position X (step S10). Then, the cooling control section 84 is adapted to intermittently control the rotating container 3 every one rotation for a predetermined stop time (for example, about 15 seconds). Therefore, when a predetermined time has elapsed (step S11), the drive motor 29 is activated to rotate the rotary container 3 about the horizontal axis 2 (step S12). When the rotary container 3 makes one rotation to the loading position X and the loading position detection switch 36 is activated (step S13), the process returns to step S10, and the rotary container 3 is rotated.
To stop.

On the other hand, every time the closing position detection switch 36 is operated, the set number CT ₂ (for example, 5) set by the cooling setting switch 37 of the setting unit 55 is sequentially subtracted (step S14). When the rotating container 3 is intermittently rotated by the set number CT ₂ and cooling is completed (step S15), the rotating container 3
3 is stopped at the feeding position X, and the supply of cooling air by the cooling fan 38 is stopped (steps S16, S17).
At the same time, the cooling indicator lamp 62 goes out.

When cooling is completed and the cooling indicator lamp 62 goes out, the lid 13 of the rotary container 3 is removed to open the opening 11, and as shown in FIG. 5, the food take-out container is placed on the carriage 7 of the base 1. After placing 9, press the eject switch 58 (step S
18). Then, the take-out control section 85 operates and the drive motor 29 is activated to rotate the rotary container 3 from the loading position X to the take-out position Y (step S19). When the rotary container 3 is rotated to the take-out position Y, the cam plate 35 operates the take-out position detection switch 37 to detect the take-out position Y (step S20), so that the rotary container 3 is stopped at the take-out position Y ( Step S21). At the take-out position Y, as shown by the chain double-dashed line in FIG. 5, the opening 10 of the rotary container 3 is directed obliquely downward, so that the rice M in the rotary container 3 is placed in this state.
Take it out.

After the rice M is taken out, the return switch 59 is pressed (step S22), and the rotation control unit 86 rotates the rotary container 3 (step S23) to return it to the loading position X. At this time, if the closing position detection switch 36 operates (step S
24) Then, the rotary container 3 is stopped at the loading position X (step S25). This completes a series of vinegar matching steps from the addition of rice M and vinegar S to mixing, steaming, cooling and removal.

Next, the operation during mixing and cooling will be described. 13 (A) to (H), the rotary container 3 is rotated about the horizontal axis 2 by 4
FIG. 14A to FIG. 14H show the states of the flow of the rotary container 3, the rice M and the cooling air when rotated at a pitch of 5 degrees.
The state of the planar movement of the rice M in (A)-(H) of FIG. 13 is shown.

When the rotary container 3 is at the loading position X, the rice M is served on the side wall 3b of the rotary container 3 as shown in FIG.
And is on the bottom wall 3a, and has an elliptical shape that is slightly longer in the rotation direction in plan view. Then, via the horizontal axis 2, the rotating container 3
The cooling air supplied inside is guided obliquely downward by the guide plate 28, circulates from the inner circumference of the rotary container 3 through the surface of the rice M in the direction of the arrow b, and then from the perforated cylindrical portion 19 of the exhaust pipe 17. Exhaust hole
It passes through 16 and is discharged to the outside.

When the rotary container 3 is rotated, the vertical cross-sectional shape of the rotary container 3 including the lid 13 is substantially quadrangular, so that the rice M in the rotary container 3 is rotated along with the bottom wall 3a, the side wall 3b, and the side wall 3b. Lid
13, the side wall 3c is sequentially pushed up and collapses from the surface side, and as shown in FIGS. 13B to 13H, moves in the direction opposite to the rotation direction of the rotary container 3. Therefore, during this movement, the rice M is much less likely to slip on the inner surface of the rotary container 3, and the stickiness of the rice M can be prevented.

When the rotary container 3 is in FIG. 13B, the rice M is on the cylindrical peripheral wall of the rotary container 3 and has a rectangular shape which is long in the rotational direction as shown in FIG. 14A. .
Then, if the rotary container 3 rotates to (C) in FIG. 13,
The rice M is on the side wall 3b and the lid 13, and the exhaust pipe 17 of the lid 13
Begin to surround the blind tube portion 18 of. At this time, the rice M has an elliptical shape as shown in FIG. 14C, but the surface level is increased by the amount of the exhaust pipe 17, and the ellipse becomes larger than that in FIG. 14A. .

On the other hand, during the rotation of the rotary container 3 from (A) to (C) of FIG. 13, the four rice cutting members 21 fixed to the exhaust pipe 17 are cut against the movement of the rice M. go. When the rotary container 3 faces downward as shown in FIG. 13 (D), the rice M surrounds the exhaust pipe 17 and rides on the lid 13, the level further rises, and as shown in FIG. 14 (D). So that it has a maximum diameter donut shape. And while the rotary container 3 is between (E) to (G) of FIG. 13, the rice M is (E) to (G) of FIG.
As shown in (G), when the rotary container 3 moves while tracing the reverse shape and is turned upward as shown in (H) of FIG. 13, the level of the rice M is lowered and (H) of FIG. ), It becomes a perfect circle. On the other hand, while the rotary container 3 moves from (E) to (G) of FIG. 13, one rice cutting member 22 fixed to the exhaust pipe 17 cuts against the movement of the rice M.

Therefore, the rice M during one rotation of the rotary container 3
14A and 14B, while being cut by the four rice cutting members 21, the width gradually narrows and extends in the rotation direction. Then, between (B) to (C), (D), and (E) of FIG. 14, the rice M is divided into two by the exhaust pipe 17 from the narrow state and widened to the maximum width, and then merges into one. Then the width becomes narrower.

Then, the width becomes the minimum width at the time of (F) of FIG. 14, and then the width becomes wide again as shown in (G) and (H), and becomes the maximum width at the time of (H). Then, the rice M is cut by the rice cutting members 21 and 22 before and after the minimum width. While continuing this series of operations, the rice M moves evenly over the whole area, and the vinegar S is mixed with the rice M along with the movement, so the rice M is evenly distributed over the rice M in a short time. Can be mixed. In addition, the rice M does not become sticky and the rice M does not form a dumpling.

The cooling air is directed downward in FIG.
In (C), diagonally downward, and in (D), sideways.
Since it is guided by 28, it constantly circulates inside the rotary container 3 through the surface side of the rice M as shown by the arrow b. And FIG.
3 (E) is guided obliquely upward to the left, (F) upwards, (G) obliquely upwards to the right, and (H) is guided laterally to the right. Flowing from.

Therefore, while the rotary container 3 makes one rotation, the flow direction of the cooling air with respect to the rice M is reversed, and the cooling air always passes through the surface of the rice M and is then discharged from the exhaust pipe 17 to the outside. Since the rice M is cooled, the rice M can be efficiently cooled and excess water can be removed, and the rice M can be prevented from sticking.

When the rotating container 3 is washed while being attached to the container mounting base 23 of the horizontal axis 2, water may enter into the cylindrical horizontal axis 2 which also serves as the sending cylinder. However, the horizontal axis 2 is not directly connected to the vertical transfer cylinder 39, the connection box 40 is interposed between them, and the horizontal axis 2 and the vertical transfer cylinder 39 are arranged at least horizontally apart from each other. Therefore, the water in the horizontal axis 2 only flows into the connection box 40, and does not enter the cooling fan 38 via the vertical transfer cylinder 39. The same applies when cleaning the inside of the horizontal axis 2. Therefore, it is sufficiently possible to insert a hose or the like into the rotary container 3 to wash away the dirt while spraying water in the rotary container 3, and put water into the rotary container 3 to close the lid 13. After that, it is also possible to wash with water while rotating the rotary container 3.

Further, the water that has entered the junction box 40 has its drain port 46.
From the drainage pipe 47 to the outside,
Water does not collect in 40. The drain pipe 47 has a trap portion 48 that bends in a U shape, and is constantly sealed with water in the trap portion 48. For this reason, the drain pipe 47 is installed in the junction box 40.
Despite being connected, no dirt, insects or the like enter the connection box 40 through the drain pipe 47, which is very hygienic.

FIG. 15 shows a second embodiment of the present invention. A vinegar supply tank 89 is provided on the support frame 8 via a support base 88, and a supply pipe 90 is provided in the horizontal axis 2 to provide the vinegar supply tank 89. It is possible to automatically supply vinegar from and the automatic supply of cleaning water at the time of cleaning. The vinegar supply tank 89 is provided with a lid 91, and vinegar S is put inside. A vinegar supply pipe 93 having a flow meter 92 is connected to the bottom of the vinegar supply tank 89, and the vinegar supply pipe 93 is connected to the supply pipe 90 via a three-way solenoid valve 94. The solenoid valve 94 has a connecting portion 95, and a water supply pipe 96 from a water pipe is connected to the connecting portion 95. A flow meter 92, solenoid valve 94
Is provided inside the support base 88.

In this embodiment, when the rice M is put in the rotary container 3 and the lid 13 is closed, and then the vinegar supply button is pressed, the solenoid valve 94 is pressed.
Since the vinegar S is connected to the vinegar supply side, the vinegar S in the vinegar supply tank 89 can be automatically supplied to the rice M in the rotary container 3 via the solenoid valve 94 and the vinegar supply pipe 93. The vinegar supply pipe amount at this time is measured by the flow meter 92, and when the set amount is reached, the solenoid valve 94 returns to neutral and the vinegar supply is automatically terminated.

When the washing button is pressed when washing the rotary container 3, the solenoid valve 94 is connected to the water supply side. Therefore, the cleaning water is supplied from the water supply pipe 96 into the rotary container 3 through the electromagnetic valve 94, so that the rotary container 3 can be cleaned with the water. At this time, the rotary container 3 may be stopped or may be rotated with the lid 13 closed.

FIG. 16 shows a third embodiment of the present invention, in which the horizontal axis
The guide plate 28 at the tip of 2 is formed in a mountain shape. By doing so, the cooling air sent from the horizontal axis 2 into the rotary container 3 can be guided in two directions.

FIG. 17 shows a fourth embodiment of the present invention, in which the rice cutting members 21 and 22 are made of U-shaped rods. That is, the rice cutting members 21 and 22 shown in FIG. 17A have both ends of a U-shaped bar member circumferentially positioned and fixed to the blind cover 20 of the exhaust pipe 17, and FIG. ) The rice cutting members 21 and 22 are
Both ends thereof are fixed to the blind cylinder portion 18 of the exhaust pipe 17 and the blind cover 20, respectively. Also in these cases, the rice M can be cut by the rice cutting members 21 and 22 when the rotary container 3 rotates.

Although each embodiment has been described above, the following configuration may be adopted. The rotary container 3 is not limited to a perfect circular shape, but may have a polygonal shape close to a cylindrical shape, for example, a hexagon or an octagon. The horizontal axis 2 may be solid, and a feed cylinder may be separately provided on the outer peripheral side in parallel or concentrically.

The container mount 23 is formed in a U shape in side view so as to receive the rotary container 3, and a horizontal axis is provided on both sides of the container mount 23.
2 may be provided to support the rotary container 3 in a two-sided manner, or the horizontal shaft 2 and the rotary container 3 may be integrally fixed. The exhaust pipe 17 is most preferably provided concentrically in the center of the lid body 13, but if it is at the substantially central portion in the axial direction of the horizontal axis 2 with respect to the lid body 13, it is located in the front in the rotation direction of the rotary container 3. Alternatively, it may be provided with a slight offset to the rear.

The lid 13 may be pivotally attached to the opening 10 side of the rotary container 3 so as to be openable and closable. In addition, in the examples, the mixture is vinegar S.

In a rice / vinegar mixing device having a cooling fan 38 for cooling the rice M, a sending cylinder 39 communicating with the cooling fan 38 side and a sending cylinder 2 communicating with the rotary container 3 side are connected to the latter sending cylinder. Since water from the 2 side does not flow into the former sending cylinder 39 side through a connection box 40, and a drain pipe 47 is provided at the bottom of this connection box 40, the inside of the rotary container 3 and the sending cylinder 2 are connected. Even when washing water is put into the rotary container 3 to wash the water, the water does not enter the cooling fan 38 side. Therefore, cleaning of the rotary container 3 and the transfer cylinder 2 is very easy, and can always be used in a hygienic state.

Further, since the water received by the junction box 40 can be drained to the outside from the drain pipe 47 provided at the bottom of the junction box 40, it is not necessary to drain the water. Further, according to the present invention as set forth in claim 2, since the ends of the former sending cylinder 39 and the latter sending cylinder 2 on the side of the connection box 40 are arranged at least horizontally apart,
Even when the water from the latter sending cylinder 2 side is prevented from flowing into the former sending cylinder 39 side, there is an advantage that the structure can be simplified.

Further, since the trap portion 48 is provided in the middle of the drain pipe 47, dust, insects and the like do not enter the connection box 40 through the drain pipe 47.
