In order to make vinegared rice by mixing vinegar with rice with the vinegar combining machine 1 having the above-described configuration, first, the drum lid 47 is opened with the mixing drum 3 in the home position shown in FIG. After being held by the lid holder 72 and supplying vinegar to the vinegar container 136 in this state, the rice is put into the drum body 46.

At this time, the mixing drum 3 is inclined forward and downward at the home position, and the upper opening surface 124 of the drum body 46 has an inclined shape that moves downward as it goes forward, so that rice can be easily put in.
Since the drum lid 47 is hinged to the drum body 46, vinegar and rice can be supplied into the drum body 46 without removing the drum lid 47, and the drum lid 47 is opened by the lid holder 72. It is not necessary to have the drum lid 47 at the time of supply of vinegar and rice, and supply of vinegar and rice can be performed easily.

  After supplying vinegar and rice to the drum body 46, the drum lid 47 is closed, the lock member 71 is locked, and the start switch 17 provided on the operation panel 20 is pressed, the mixing drum 3 rotates in the reverse rotation direction R. To do. When the mixing drum 3 rotates in the reverse rotation direction R, as the mixing drum 3 rotates in the reverse rotation direction R, the vinegar container 136 passes through the front side of the drum support shafts 25L and 25R as shown in FIG. It moves above the drum support shafts 25L and 25R, and passes above the drum support shafts 25L and 25R and moves to the rear side of the drum support shafts 25L and 25R.

  At this time, while the vinegar storage part 136 moves to the front of the drum support shafts 25L and 25R, the vinegar storage container 138 is a container having an opening at the front end and the vinegar discharge part 139 is provided on the preceding side in the reverse rotation direction R. Therefore, there is almost no leakage of the vinegar 152 from the vinegar storage container 138. Moreover, even if the vinegar storage container 138 moves to the front of the drum spindles 25L and 25R, in this state, the rice remains on the bottom 117b side of the peripheral wall 117 of the drum body 46, and the vinegar discharge part 139 is made of rice. Since it is blocked, the discharge of vinegar 152 is suppressed.

  After that, when the vinegar container 136 passes directly in front of the drum support shafts 25L and 25R and the rice is lifted to some extent, the rice falls by its own weight. When the rice falls under its own weight, the vinegar discharging part 139 is opened, and vinegar starts to be discharged from the vinegar discharging part 139. And the vinegar 152 inside the vinegar storage container 138 is the reverse rotation direction R of the vinegar storage container 138 from the rearward direction R rearward of the position directly above the drum spindles 25L and 25R to the rearward direction R of the position directly above the drum spindles 25L and 25R. While moving to the front position, the rice is dropped and supplied in a shower shape, and vinegar is automatically and evenly spread on the rice. Thereby, vinegar can be mixed uniformly with rice.

  Further, when the mixing drum 3 is rotated once for the first time, the rotation speed of the mixing drum 3 is controlled so that all the vinegar 152 stored in the vinegar storage container 138 is dropped and discharged. That is, when the vinegar 152 is dropped and supplied to the rice in the form of a shower, the speed is slower than the starting speed when the mixing drum 3 rotates from the home position (for example, 30% of the starting speed). The mixing drum 3 is controlled to rotate at a speed of 1).

  When the vinegar container 136 passes a position just above the drum support shafts 25L and 25R and moves a predetermined amount (when the mixing drum 3 rotates a predetermined angle from the state where the vinegar container 136 is positioned directly above the drum support shafts 25L and 25R) ), The mixing drum 3 rotates at a faster rotation speed than when supplying vinegar. The rotation speed of the mixing drum 3 after the supply of vinegar may be slightly slower than the rotation speed at the start (for example, 90% of the rotation speed at the start), or the same speed as the rotation speed at the start. It may be.

When the mixing drum 3 is rotated, the rice is lifted up to a predetermined height and dropped repeatedly. When the rice drops, the rice hits the stirring rod 129 and is loosened (shaved) and stirred. , Vinegar is mixed with rice.
At this time, the cooling air is supplied into the mixing drum 3 while the mixing drum 3 rotates in the backward rotation direction R, and the rice is cooled. Thereafter, when the predetermined time has elapsed, the stickiness of the rice (vinegared rice) becomes stronger with the passage of time, so that the mixing drum 3 rotates in the reverse direction R while decreasing the rotational speed stepwise or steplessly according to the elapsed time. Rotate to.

  On the other hand, when the mixing drum 3 is rotated in the backward rotation direction R, the lower drum lid regulating member 105 is in the overhanging engagement portion 50 of the flange portion 49 of the drum lid 47 as shown in FIG. However, the upper drum lid regulating member 105 interferes with the overhanging engaging portion 50 of the flange portion 49 of the drum lid 47. When the mixing drum 3 rotates in the backward rotation direction R and the overhanging engaging portion 50 comes into contact with the upper drum lid regulating member 105, the drum lid regulating member 105 is pressed against the overhanging engaging portion 50, and The upper portion swings forward about the swing support shaft 108. As a result, the upper drum lid regulating member 105 automatically escapes from the overhanging engaging portion 50 of the drum lid 47 (the upper drum lid regulating member 105 is retracted from the interference region 143 with the overhanging engaging portion 50 of the drum lid 47. To do).

  Further, when the mixing drum 3 rotates in the backward rotation direction R, the lock release member 104 interferes with the guide guide 88 of the lock member 71 as shown in FIG. When the mixing drum 3 rotates in the reverse rotation direction R and the lock member 71 comes into contact with the lock release member 104, the lock release member 104 is pressed by the lock member 71, and the upper portion of the swing member 106 rotates around the swing support shaft 108. Swings forward. As a result, the unlocking member 104 automatically escapes from the locking member 71 (the unlocking member 104 retracts from the interference region 144 with the locking member 71).

  The drum lid regulating member 105 is released from the drum lid 47 and the unlocking member 104 is released from the lock member 71 by the swing member 106, the guide groove 111, the regulating pin 112, etc. (the drum lid regulating member 105 is connected to the drum lid 47). The escape means is configured to retract from the interference region 143 and retract the lock release member 104 from the interference region 144 with the lock member 71.

When the overhanging engagement portion 50 is disengaged from the upper drum lid regulating member 105 and the lock member 71 is detached from the unlocking member 104, the swing member 106 (drum lid regulating member 105 and unlocking member 104) is in its original position. Return to.
On the other hand, when the mixing drum 3 is rotated several times in the backward rotation direction R and the rice is moderately stirred, the unevenness process (set for a set time with the blower 10 stopped) was then set. The mixing drum 3 is intermittently rotated in the reverse rotation direction R at the rotation speed), the cooling process (the mixing drum 3 is intermittently rotated in the reverse rotation direction R at the set rotation speed for a set time while the blower 10 is operated) Or, the mixing drum 3 returns to the home position and stops. With the above, vinegared rice in which vinegar is uniformly mixed with rice is completed.

After the mixing drum 3 has returned to the home position, automatically or automatically by pressing the discharge switch 19 provided on the operation panel 20 to automatically discharge the finished vinegared rice (food ingredients). Operation is performed.
This discharging operation is performed when the mixing drum 3 rotates in the forward rotation direction F from the home position.

First, when the mixing drum 3 rotates in the forward rotation direction F from the home position shown in FIG. 34 (a), the lock member 71 engages with the lock release member 104, and as shown in FIG. 34 (b), the lock member 71 is unlocked.
The automatic unlocking of the lock member 71 will be described in detail. As shown in FIG. 35A, the guide guide 88 of the lock member 71 is located above the unlock member 104 when the mixing drum 3 is in the home position. At this time, the unlocking guide surface 88a of the guide guide 88 is inclined obliquely downward and forward.

  When the mixing drum 3 rotates in the forward rotation direction F from this home position, as shown in FIG. 35B, the lock member 71 moves downward and the lower end side of the lock release guide surface 88a contacts the lock release member 104 from above. I win. Further, when the mixing drum 3 rotates in the forward rotation direction F, as shown in FIGS. 35 (c) and 35 (d), the lock member 71 moves downward with respect to the lock release member 104, thereby locking the lock member 71. The release member 104 is forcibly pushed forward. As a result, the lock member 71 swings around the pivot pin 98, the lock engaging portion 92 is detached from the lock engaging member 99, and the lock of the lock member 71 is released. At this time, the unlocking member 104 relatively rolls with the unlocking guide surface 88a facing upward. Thereafter, when the mixing drum 3 rotates in the forward rotation direction F, the lock release member 104 is disengaged from the lock release guide surface 88a (guide guide 88) of the lock member 71.

  When the lock of the lock member 71 is released and the lock release member 104 is disengaged from the lock release guide surface 88a, and the mixing drum 3 further rotates in the forward rotation direction F, as shown in FIG. The front end side of the lower surface of the overhanging engagement portion 50 contacts the upper drum lid regulating member 105 from above, and the swinging operation of the drum lid 47 toward the drum body 46 is restricted.

  When the drum main body 46 further rotates in the forward rotation direction F from this state, as shown in FIG. 37, the overhanging engaging portion 50 contacts the lower drum lid regulating member 105 and the drum lid 47 side of the drum lid 47 The drum body 46 has an inclined vinegar rice discharging posture in which the upper opening surface 124 is inclined downward and the upper opening surface 124 moves downward as the upper opening surface 124 moves downward. In this posture, the drum body 46 is temporarily stopped.

  On the other hand, the vinegared rice in the drum main body 46 gradually falls naturally into the vinegared rice storage box 39 from when the upper opening surface 124 of the drum main body 46 starts to face downward until the drum main body 46 assumes the vinegared rice discharging posture. When the drum main body 46 is in the vinegared rice discharging posture, the whole is dropped and discharged into the vinegared rice storage box 39 (therefore, the horizontal surface of the vinegared rice support surface 123 when the drum main body 46 is in the vinegared rice discharging posture). The inclination angle with respect to is greater than the angle of repose).

After stopping for a predetermined time in the vinegared rice discharging posture (when vinegared rice is discharged), the drum body 46 rotates in the reverse rotation direction R and returns to the home position.
In addition, when the mixing drum 3 returns to the home position after discharging the vinegared rice, the guide guide 88 of the lock member 71 contacts the lock release member 104. In this case, the arc-shaped corner portion of the guide guide 88 The unlocking member 104 is guided by the corner portion 88d so as to pass through the unlocking guide surface 88a from the front surface 88b or the upper surface 88c of the guide guide, and the guide guide 88 of the locking member 71 is guided by the unlocking member 104. Don't get stuck in.

In the vinegar mixing machine 1 having the above-described configuration, the arc that touches the drum rotation axis X and contacts the upper part of the inner surface of the drum lid 47 on the leading and trailing sides in the rearward direction R of the drum lid 47 of the mixing drum 3. W
Further, bulging portions 122F and 122R that bulge outward are provided, and the drum main body 46 is centered around the drum rotation axis X on the leading and trailing sides in the reverse direction R of the drum main body 46 of the mixing drum 3. There are provided bulging portions 119F and 119R that bulge outward from the arc V in contact with the lower surface of the inner surface. By providing the bulging portions 119F, 119R, 122F, and 122R, the space ratio inside the mixing drum 3 can be increased.

  Further, when the mixing drum 3 is rotated in the backward rotation direction R and the rice is stirred, the rice is rotated and lifted together with the mixing drum 3, and when it is lifted to a certain extent, it naturally falls and hits the stirring rod 129 and is loosened and stirred. However, by providing the bulging portions 119F, 119R, 122F, 122R, the rice can be lifted to a high position and dropped from the high position onto the stirring rod 129.

And stirring performance can be improved by raising the space rate inside mixing drum 3, and dropping rice to stirring rod 129 from a high position.
Moreover, when the drum main body 46 is set to the vinegared rice discharging posture, the inner surface of the front portion 117a of the peripheral wall 117 of the drum main body 46 is used as the vinegared rice supporting surface 123 when the rice is discharged. By forming the bottom end 117b of the peripheral wall 117 of the main body 46 from the bottom 117b side toward the upper opening, the inclination angle with respect to the horizontal of the vinegared rice support surface 123 when the drum main body 46 is in the vinegared rice discharging posture is increased. Emission can be improved.

In addition, when discharging the vinegared rice, the drum body 46 can be moved away from the stirring bar 129 by the bulging portion 119F in the reverse rotation direction R of the drum body 46. Can be reduced and contribute to the improvement of vinegared rice discharge performance.
Further, when the inner surface of the rear portion 117d of the peripheral wall 117 of the drum main body 46 is formed so as to widen from the bottom 117b side of the peripheral wall 117 of the drum main body 46 toward the upper opening in the same manner as the vinegared rice support surface 123, As the length on the lower opening surface 133 side becomes longer, the hinge shaft 79 is displaced rearward.

Then, as shown by a virtual line in FIG. 38, when the drum main body 46 is in the vinegared rice discharging posture, the lower end position of the drum lid 47 is lowered. Also, since the vinegared rice storage box 39 is disposed below the mixing drum 3, if the lower end position of the drum lid 47 is lowered, the height of the mixing drum 3 must be increased accordingly.
On the other hand, in the mixing drum 3 of the present embodiment, the inner surface of the rear portion 117d of the peripheral wall 117 of the drum main body 46 is formed substantially orthogonal to the upper opening surface 124 of the drum main body 46. 46 is formed such that the longitudinal length H2 of the upper opening surface 124 of the drum main body 46 on the rear side of the drum rotational axis X is smaller than the longitudinal length H1 of the upper opening surface 124 of the drum 46 on the front side of the drum rotational axis X. Therefore, the hinge fulcrum of the drum lid 47 can be moved to the front side, and the front-rear length on the lower opening surface side of the drum lid 47 can be shortened. In this case, it is possible to suppress the lower end position of the drum lid 47 from being lowered, and the height of the mixing drum 3 can be suppressed.

In this embodiment, by rotating the drum body 46 in the forward rotation direction F, the lock member 71 is engaged with the lock release member 104 and the lock of the lock member 71 is automatically released. Therefore, the lock member 71 can be easily unlocked.
When the drum body 46 is further rotated in the forward rotation direction F after the lock member 71 is unlocked, the drum body 46 assumes a vinegared rice discharging posture with the upper opening surface 124 facing downward, and the drum body 46 Since the vinegared rice falls naturally and is discharged, even if it is the mixing drum 3 of the type in which the drum body 46 is closed with the drum lid 47 without opening, the finished vinegared rice is automatically taken out from the mixing drum 3 It is possible and convenient. Further, vinegared rice can be taken out from the drum body 46 without removing the drum lid 47.

Further, when the drum body 46 is brought into the vinegared rice discharging posture, the drum lid regulating member 105 engages with the drum lid 47 and regulates the drum lid 47 from swinging toward the drum body 46 side. 47 does not interfere with the discharge of vinegared rice and can easily discharge vinegared rice.
Further, when the mixing drum 3 is rotated in the backward rotation direction R and the rice is being stirred, the drum lid regulating member 105 is automatically retracted from the interference region 143 with the drum lid 47 and the unlocking member 104 is removed. Automatically retracts from the interference region 144 with the lock member 71, so that the operation of switching the drum lid restricting member 105 to the position to retract from the interference region 143 with the drum lid 47, or the lock release member 104 with the lock member 71. It is not necessary to perform a work of switching to a position for retreating from the interference area 144, which is convenient.

  The fixed element 148 is formed with a guide groove (not shown) that guides the guide pin 151 provided on the movable element 149 so as to be movable in the vertical direction, and the movable element 149 has a predetermined range with respect to the fixed element 148. It can be moved up and down. The movable element 149 is close to the drum support shaft 25R at the lower end position of the movement range, and restricts the upward movement of the drum support shaft 25R.

In the structure shown in FIG. 42A, an overload is applied to the meshing portion of the driven gear 52 and the drive gear 16, and the force that pushes the drum support shaft 25R upward is the drum support shaft 25R. As a result, the movable element 149 is pushed up against the urging force of the urging element 150 by the drum support shaft 25R, and the engagement between the driven gear 52 and the driving gear 16 is released.
The structure shown in FIG. 42B shows a structure in which the shaft restricting member 58 is formed of a spring plate. The shaft restricting member 58 composed of this spring plate is disposed close to the drum support shaft 25R with the front upper portion 58a fixed to the lower surface of the cover member and the rear lower portion 58b as a free end. The intermediate portion 58c of the shaft restricting member 58 is inclined so as to move backward as it goes downward.
