Concretely, in each stirring mode, since the set value of the rotation speed of the mixing drum 3 at the time of stirring and the set value of the rotation time (stirring time) of the mixing drum are different from each other, Whereby fine stirring can be performed.

24 (a) shows an example of a plurality of stirring modes provided in the stirring control section 184. As shown in Fig. As shown in Fig. 24A, for example, since the stirring control unit 184 has three stirring modes (first stirring mode, second stirring mode and third stirring mode), the stirring control unit 184) sequentially execute the respective stirring modes (the first stirring mode, the second stirring mode and the third stirring mode) in order. For the convenience of explanation, the stirring control unit 184 proceeds to explain the first stirring mode, the second stirring mode and the third stirring mode. Naturally, the number of stirring modes executed by the stirring control section 184 is not limited to this.

As shown in FIG. 24A, the first stirring mode is the first mode (process) to be performed, and the rotational speed (drum rotational speed) of the mixing drum 3 at the time of stirring is different from the other stirring modes 2 stirring mode, and the third stirring mode) (the drum rotation speed is " high "). The second stirring mode is a mode executed next to the first stirring mode. The drum rotation speed at the time of stirring is set lower than the first stirring mode and higher than the third stirring mode (" middle " The third stirring mode is a mode executed next to the second stirring mode, and the drum rotation speed at the time of stirring is set lower than the second stirring mode (drum rotation speed "small"). The agitation time in the first agitation mode, the second agitation mode and the third agitation mode is a constant value.

The drum rotation speed and stirring time in each of the stirring modes (the first stirring mode, the second stirring mode, and the third stirring mode) are set in advance so as to make the granular plant material and the liquid plant material into a desired mixed state or the like. That is, the drum rotation speed and stirring time in each of the stirring modes (the first stirring mode, the second stirring mode, and the third stirring mode) are stored in the control device 9. In this embodiment, since the granular plant material is " rice ", the liquid plant material is " vinegar ", and the rice is made by mixing rice and vinegar, As described above, the drum rotation speed is lowered step by step with the elapse of time by each of the stirring modes (the first stirring mode, the second stirring mode, and the third stirring mode). That is, the stirring control unit 184 gradually decreases the drum rotation speed in accordance with the length of the stirring time at the time of stirring the liquid plant material and the granular plant material. That is, in the stirring operation, the stirring control unit 184 makes the rotational speed of the mixing drum 3 in the stirring mode to be executed later later than the rotational speed of the rotational mode to execute first. Thereby, in the initial stage of stirring, by rotating the mixing drum 3 at a relatively high speed, the vinegar can be mixed into the whole rice while the rice is warm. In the middle stage or the late stage of the stirring in which the rice and the vinegar are relatively mixed, by rotating the mixing drum 3 at a gradually slower speed, it is possible to make time for the rice to come into contact with air in the mixing drum 3 The temperature of the rice can be lowered. The drum rotation speed or stirring time in each stirring mode may be changed using the operation panel 20 or the like. Further, in the stirring step, the number of stirring modes may be changed using the operation panel 20 or the like.

Fig. 25 shows examples of the rotation speed of the mixing drum 3 in the stirring step, the steam rising process, the cooling step, and the operating time of each step.

As shown in Fig. 25, the stirring step A represents the drum rotation speed and the operation time which are performed in the first stirring mode, the stirring step B represents the drum rotation speed and the operation time which are performed in the second stirring mode, And C represents the drum rotation speed and the operation time which are executed in the third stirring mode.

The section from the point P3 to the point P4 in the stirring step A becomes the stirring operation (stirring operation mode) in the first stirring mode, and the drum rotation speed in the stirring operation in the first stirring mode (stirring step A) Is 90% with respect to the rated rotation speed (set rotation speed) of the drive motor 7. The interval from the point P4 to the point P5 in the stirring step B becomes the stirring operation in the second stirring mode and the drum rotation speed in the stirring operation in the second stirring mode (stirring step B) Of the rated rotational speed of the motor. The interval from the point P5 to the point P6 in the stirring step C becomes the stirring operation in the third stirring mode and the drum rotation speed in the stirring operation in the third stirring mode (stirring step C) Of the rated rotational speed of the motor.

Although the drum rotation speed in the first agitation mode, the drum rotation speed in the second agitation mode, and the drum rotation speed in the third agitation mode decelerate stepwise in accordance with the elapsed time as described above, the change in the drum rotation speed 90 %, 50%, 20%) is inversely proportional to the situation in which the strength of the sticky state gradually increases when the rice and the vinegar are mixed (at the time of stirring). When the rice and the vinegar are stirred in the stirring process, the stickiness of the rice gradually becomes stronger as the time passes. However, as described above, the stirring control unit 184, The drum rotational speed is gradually reduced in accordance with the strength of the sushi roll, so that the stickiness of the sushi can be prevented from becoming too strong.

The agitation control unit 184 has a supply mode. This feeding mode is a mode for appropriately dropping the liquid food (vinegar) in the liquid containing portion 136 toward the granular food (rice) before the start switch 170 is pressed and the mixing drum 3 enters the stirring operation. to be. That is, the feeding mode is operated before the stirring operation is started (point P1) in the first stirring mode, and the vinegar is dropped toward the rice by controlling the rotating position of the mixing drum 3 or the drum rotation speed. In other words, in the first agitation mode first stirring mode, the liquid containing portion 136 is moved to the feeding position by the rotation of the mixing drum 3 in order to drop the vinegar in the liquid containing portion 136 toward the rice And a feeding mode for moving the paper is added.

Next, the supply mode will be described in detail.

First, when the mixing drum 3 is at the initial position (home position), that is, as shown by the arrow A in Fig. 26, the liquid containing portion 136 is directly below the drum supporting shafts 25L and 25R When the start switch 170 is pressed and the rotation start instruction of the mixing drum 3 is input to the control device 9 when the control device 9 is in the home position, the stirring control part 184 of the control device 9 starts the supply mode . The stirring control unit 184 outputs a command for forward rotation to the drive motor 7 to rotate the mixing drum 3 backward so that the liquid containing portion 136 is moved from the home position indicated by arrow A And is moved toward the supply position. This feeding position is a position for dropping the vinegar toward the rice and is in a predetermined range when viewed in the rotating direction of the mixing drum 3. [

26, when the mixing drum 3 is rotated in the backward rotational direction R from the groove position, the mixing drum 3 rotates in the backward rotational direction R, The portion 136 moves in the main direction from the home position and moves toward the upper side of the drum supporting shafts 25L and 25R through the front side of the drum supporting shafts 25L and 25R. The liquid discharging portion 139 of the liquid containing portion 136 is positioned at a position where the liquid receiving portion 136 is substantially at the same height as the drum supporting shafts 25L and 25R Or the vinegar in the liquid storage portion 136 does not reach the liquid discharge portion 139, the vinegar does not drop from the liquid storage portion 136 toward the rice.

The liquid containing portion 136 is positioned higher than the drum supporting shafts 25L and 25R and the liquid containing portion 136 is slightly inclined (arrow C) Start dropping toward rice. That is, the liquid containing portion 136 is positioned at a position higher than the drum supporting shafts 25L and 25R and the leading end of the liquid containing portion 136 is inclined upward (the leading end is the upper side and the trailing end is the lower side) Is the starting point of the feeding position for dropping the vinegar toward the rice. When the liquid storage portion 136 moves in the main direction and is directly above the drum support shafts 25L and 25R (arrow D), the vinegar in the liquid storage portion 136 continues to fall toward the rice. The position at which the liquid storage portion 136 is directly above the drum support shafts 25L and 25R becomes the midpoint of the supply position. The position where the liquid accommodating portion 136 moves in the main direction and which is symmetrical with respect to the starting point of the supplying position (arrow E), that is, the leading end portion of the liquid accommodating portion 136 is in the downward inclined posture And the trailing end becomes the upper side) becomes the end point of the feeding position for dropping the vinegar toward the rice.

In the supply mode, the drum rotation speed from the home position to the starting point of the supply position is increased to raise the liquid containing portion 136 to the supply start position as soon as possible ). More specifically, as shown in Fig. 25, a point P1 in the first stirring step indicates a point in time when the mixing drum 3 starts rotating, and a point P2 indicates a point at which the liquid containing portion 136 reaches the start point of the home position As shown in FIG. In the supply mode, the drum rotational speed (third rotational speed) is supplied to the driving motor (third rotational speed) during the time T1 from the point P1 to the point P2, that is, 7) is set to 100% with respect to the rated rotational speed of the first agitation mode, and is faster than the drum rotational speed (90% of the second rotational speed and the rated rotational speed) at the time of agitation in the first agitation mode. That is, the first rotational speed is made faster than the second rotational speed at which vinegar is supplied and stirring is started.

In this regard, the liquid containing portion 136 containing the vinegar can quickly be set to the feeding position from the groove position, and the liquid containing portion (for example, , Vinegar) can be prevented from falling down. In other words, a large centrifugal force acts on the outer side during the period from the groove position to the supply position by increasing the rotational speed of the drum while the liquid storage portion 136 extends from the groove position to the supply position. 136 from being discharged. In other words, the vinegar in the liquid containing portion 136 can be reliably dropped on the rice.

In the supply mode, when the liquid storage portion 136 is in the supply position, that is, in the range of the end point of the supply position from the start of the supply position, It is promoting the drop of vinegar to be discharged. Specifically, as shown in Fig. 25, a point P3 in the first agitating step indicates a point in time at which the liquid containing portion 136 reaches the end point of the home position. In the supply mode, the drum rotation speed (first rotation speed) is set to the rated rotation speed of the drive motor 7 during the time T2 from the point P2 to the point P3, that is, Is set to 30% with respect to the speed, and is made later than the drum rotational speed (second rotational speed) at the time of stirring in the first agitation mode. In this embodiment, the first rotation speed is reduced to about 1/3 of the second rotation speed. In this respect, the time for the liquid containing portion 136 to be positioned above the rice can be lengthened, whereby the vinegar in the liquid containing portion 136 can be dropped toward the rice at once.

In addition, the relationship between the timing at which the supply position is made at the home position, that is, the drum rotation speed and the time (driving time) can be obtained through experiments or simulations. The supply position (the position of the liquid containing portion 136) at which the liquid food in the liquid containing portion 136 starts dropping may be obtained by experiments or simulations. Alternatively, do. For example, a line sensor for irradiating detection light in parallel with the upper wall 138a of the liquid containing portion 136 may be provided on the inner wall of the mixing drum 3, and the liquid containing portion The position of the feeding portion 136 may be set as the feeding position. The arrangement position and the arrangement method of the sensors and the like are not limited to those described above.

22, the control device 9 includes a steam boiler control unit 185 for executing a steam boiler process, a cooling control unit 186 for executing a cooling process, and a discharge control unit 186 for executing a discharge process. (187). The steam boiler control unit 185, the cooling control unit 186 and the discharge control unit 187 are constituted by programs stored in the control unit 9 or the like.

When the agitation process by the agitation control unit 184 is completed, the steam boiling process by the steam boiler control unit 185 is executed. More specifically, when the third stirring mode is completed by the stirring control unit 184, the steam boiler control unit 185 controls the driving motor 7 as shown in Fig. 25 in a state in which the blowing unit 8 is stopped, And outputs a signal for intermittently rotating. For example, the steam boiler control unit 185 outputs a forward rotation command to the drive motor 7 at intervals of time T3 to perform the steam boiler process. At this time, the steam entry control device 185 sets the drum rotation speed to 90% with respect to the rated rotation speed (set rotation speed) of the drive motor 7, for example.

When the steam boiling process by the steam boiler control unit 185 is completed, the cooling process by the cooling control unit 186 is executed. Specifically, the cooling control unit 186 first reads the cooling conditions (air volume, drum rotation speed, drum rotation interval, and the like) stored in advance in the control unit 9, (Cooling command) for blowing cooling air (air) to the cooling fan (blowing motor) 160. Further, the cooling control section 186 outputs a command (rotation command) for rotating the drive motor 7 so as to be the drum rotation speed and the drum rotation interval. 25, for example, the cooling control unit 186 sets the drum rotation speed to 70% with respect to the rated rotation speed of the drive motor 7, and at the interval of time T4, And outputs a rotating command to the drive motor 7. [ The cooling control unit 186 stops the mixing drum 3 at the home position at the end of the cooling step. That is, the cooling control unit 186 stops the command to the drive motor 7 when the home signal from the first detection device 40 is input to the control device 9, and the mixing drum 3 is stopped at the home position The cooling process is terminated.

When the cooling process by the cooling control unit 186 is completed, the discharge process by the discharge control unit 187 is executed. Fig. 27 shows a control flow by the discharge control section 187. Fig.

As shown in Fig. 27, the discharge control section 187 first determines whether the mixing drum 3 is at the discharge position (planting / discharging posture) when performing the discharging process. That is, the discharge control section 187 judges whether or not the discharge signal from the second detection device 45 is inputted to the control device 9 (S10). Here, when the discharge signal is not inputted to the control device 9, the discharge control section 187 proceeds to the next process.

The discharge control section 187 judges whether or not the planting container box 39 is installed on the base frame 4. [ That is, the discharge control section 187 judges whether or not the installation signal from the first detection device 40 is input to the control device 9 (S11). Here, when the installation signal is input to the control device 9, the discharge control section 187 proceeds to the next process.

The discharge control section 187 judges whether or not the mixing drum 3 is in the home position. That is, the discharge control section 187 determines whether a home signal from the second detection device 40 is input to the control device 9 (S12). When the home signal is input to the control device 9, the emission control section 187 proceeds to the next process.

Then, when the mixing drum 3 is in the home position, the discharge control unit 187 outputs a reverse rotation command to the drive motor 7 to rotate the mixing drum 3 forward (S13). Then, the discharge control section 187 judges whether or not the mixing drum 3 is at the discharge position (planting / discharging posture) as shown in Fig. That is, the discharge control section 187 judges whether or not the discharge signal from the second detection device 40 is inputted to the control device 9 (S14). When the discharge signal is inputted to the control device 9 and the planting / discharging posture of the mixing drum 3 is detected, the discharge control section 187 proceeds to the processing of S15.

When the mixing drum 3 is in the discharge position, the discharge control unit 187 stops the command to reverse the rotation to the drive motor 7 (S15). Further, it is preferable that the discharge control section 187 notify the discharge of the plant material after the plant material is discharged by a sound, a buzzer or the like.

In this manner, the discharge control section 187 can automatically discharge the sushi in the mixing drum 3 to the planting container box 39. [

In the above-described embodiment, the cooling process is terminated when the mixing drum 3 is in the groove position, and then the process proceeds to the discharging process. Instead, the mixing drum 3 may be moved The cooling process may be terminated and the process may be shifted to the discharge process.

28 shows the discharging process in the case where the cooling process is ended without using the mixing drum 3 as the groove position. Steps S10 to S15 shown in Fig. 28 are the same as those shown in Fig.

When the mixing drum 3 is not at the home position (S15, NO), the discharge control unit 187 shifts to the home return process (S16). Specifically, the discharge control section 187 outputs a command for forward rotation to the drive motor 7 to rotate the mixing drum 3 backward, and at the time point when a home signal is input to the control device 9 3) becomes the home position), the command for forward rotation to the drive motor 7 is stopped. In the above example, the mixing drum 3 is automatically returned to the home position, but the mixing drum 3 may be manually returned to the home position. In this case, the discharge control section 187 permits the input of the home return switch 172 or the rearward rotation switch 176. When the groove return switch 172 is depressed, the discharge control section 187 returns the mixing drum 3 to the home position as described above. When the rear rotation switch 176 is depressed, the discharge control section 187 causes the rear rotation switch 176 are pressed, a forward rotation command is outputted to the drive motor 7 to rotate the mixing drum 3 backward, and when the home signal is input to the control device 9, forward rotation to the drive motor 7 The command is stopped. As described above, the discharge control section 187 can discharge the completed sushi to the plantation containing box 39.

After discharging the sushi in the mixing drum 3 to the planting container 39 with the mixing drum 3 at the discharging position (planting and discharging posture), the discharging control unit 187 controls the mixing drum 3 And proceeds to the process of returning to the home position in the plant material discharge posture. Specifically, the discharge control section 187 causes the mixing drum 3 to rotate in one direction (backward rotational direction) after a predetermined elapsed time (for example, several tens of seconds to several minutes) after the mixing drum 3 reaches the planting / (The home return switch 172 or the rearward rotation switch 176) for rotating the housing. When the groove return switch 172 or the rear rotary switch 176 is pressed, the discharge control unit 187 performs a predetermined process to return the mixing drum 3 to the home position. The process when the home return switch 172 or the rearward rotation switch 176 is pressed is the same as the above description. According to this, by manually operating the switch (the groove return switch 172 or the rear rotary switch 176) after discharging the ingredients (sushi) in the mixing drum 3, the mixing drum 3 is moved to the home position So that new ingredients can simply be put into the mixing drum.

Further, the mixing drum 3 is returned to the home position in the planting / discharging position by the switch, but instead of this, the mixing drum 3 may be automatically returned from the planting / discharging position to the home position. For example, after a predetermined elapsed time (for example, several minutes) after the mixing drum 3 reaches the planting / discharging posture, the discharge control section 187 causes the driving motor 7 to rotate the mixing drum 3 backward And returns the mixing drum 3 to the home position in the planting / discharging position. At this time, when the home signal indicating that the mixing drum 3 is returned to the home position is inputted to the control device 9, the discharge control section 187 stops outputting the signal for rotating the mixing drum 3 backward. In this case, after the mixing drum 3 is rotated backward and the sushi is discharged, the mixing drum 3 can be returned to the home position by automatically switching the rotation of the mixing drum 3 from forward rotation to forward rotation Whereby it becomes possible to insert a new plant material into the mixing drum 3.

Incidentally, the stirring control section 184 enables the blowing device 8 to be operated at the time of stirring. Specifically, the stirring control unit 184 operates the air blowing device 8 (blower 10) to perform mixing operation when the stirring operation is performed by at least the first stirring mode, the second stirring mode and the third stirring mode And air is blown into the drum (3). That is, a blowing mode is added to the first agitation mode, the second agitation mode, and the third agitation mode.

24 (b) shows a pattern of blowing air to be executed in the first stirring mode, the second stirring mode and the third stirring mode, that is, in the blowing mode in the first stirring step, the second stirring step, and the third stirring step And the like. As shown in Fig. 24 (b), for example, in the pattern (1), blowing is performed at the time of stirring in all the stirring steps, and in the pattern (2) And in the pattern (3), air is blown at the time of stirring in the first stirring step. The pattern shown in FIG. 24 (b) may be selected by the operation panel 20, or a predetermined pattern may be stored in advance in the control device 9 in advance.

The air blowing by the air blowing device 8 performed at the time of stirring is performed to guide water vapor (steam) exiting the rice from the inside of the mixing drum 3 to the outside of the mixing drum 3 by air, Is set to be lower than the air flow rate of the cooling air. In other words, the blowing performed at the time of stirring is the degree of venting the steam to the outside, and it is a breeze.

As described above, when the air blowing device 8 (blower 10) is operated by the stirring control section 184 while stirring, air is introduced into the mixing drum 3 as indicated by an arrow W1 in FIG. 13, The introduced air W1 pushes the water vapor W2 coming out of the rice toward the exhaust hole 29 of the left side frame 5L and the water vapor W2 together with the introduction air W1, Enters the exhaust chamber 35 through the hole 29 and is exhausted from the exhaust chamber 35 to the outside through the exhaust port 36. [ As a result, when the rice is mixed with the rice, the rice is able to keep the fragrance of the vinegar because the rice can blow the extra moisture, that is, steam. In addition, it is possible to suppress adhesion of steam (water droplets) to the inner wall of the mixing drum 3. [

It is also to be understood that the embodiments disclosed herein are illustrative and non-restrictive in all respects. It is intended that the scope of the invention be indicated by the appended claims rather than the foregoing description and that all changes that come within the meaning and range of equivalency of the claims are intended to be embraced therein.

In the above-described embodiment, the bubble is sent to the mixing drum 3 at the time of stirring to suppress the adhesion of the water droplet to the mixing drum 3. However, when stirring is not performed, for example, It may be introduced into the drum 3. In addition, although the vinegar mixer described above performs the steam boiling process, the steam boiling process may be omitted.

In the above-described embodiment, the vinegar mixer is described with reference to the liquid planting material as "vinegar" and the granular planting material as "rice." However, the liquid planting material may be other than "vinegar" The granular planting material may be other than "rice".

[ Thereby, when inserting the vinegar storage container 138 into the container storage portion 137, the front and rear are not mistaken.

A vinegar outlet 139 formed by a plurality of small holes 139a passing through the upper wall 138a is formed on the upper wall 138a of the vinegar storage container 138. [ The vinegar outlet portion 139 is formed on the leading side of the mixing drum 3 in the backward rotational direction R and the trailing side of the upper wall 138a of the vinegar storage container 138 in the backward rotational direction R, So that the vinegar reservoir 138 is prevented from leaking out.

In order to store the vinegar in the vinegar reservoir 138, the vinegar is injected onto the upper wall 138a of the vinegar reservoir 138 from the upper opening of the drum body 46. [ The introduced vinegar mainly enters the vinegar storage container 138 from the vinegar discharge section 139 and is stored in the vinegar storage container 138.

The structure for supplying vinegar to the rice in the mixing drum 3 can be simplified by providing the vinegar receiving portion 136 on the bottom portion 117b of the peripheral wall 117 of the drum main body 46 as described above The cost can be reduced. In addition, by providing the vinegar receiving portion 136 for supplying the vinegar to the rice in the mixing drum 3, the mixing drum 3 can be easily attached and detached. Further, by removing the vinegar storage container 138 from the container storage portion 137, the vinegar storage portion 136 can be easily cleaned. Further, the vinegar storage container 138 can be easily cleaned by configuring the vinegar storage container 138 in the shape of the opening at the front end.

The mounting groove 132 formed in the drum main body 46 is formed at a position corresponding to the four corners of the bottom opening 118 of the drum main body 46 and the upper surface 138a of the vinegar storage container 138 The to-be-pressed piece 140 penetrating into the lower end of the mounting groove 132 is formed at the front, rear, left, and right corners of the mounting groove 132. Therefore, when the rod supporting member 130 of the agitating member 128 is mounted in the mounting groove 132 of the drum main body 46, the barrel supporting member 130 is pushed by the barbed piece 140, (138) is released from the container storage portion (137).

As described above, by making the rod supporting member 130 of the agitating member 128 a regulating member for regulating the separation of the vinegar storage container 138 from the vinegar receiving portion 136, members can be used in common The cost can be reduced.

A drain hole 141 is formed in the bottom wall 137d of the container storage portion 137. The drain hole 141 is openable and closable by an opening / closing cap 142 that is twisted into the drain hole 141 It is blocked.

By providing the drain holes 141, it is possible to easily remove the moisture in the mixing drum 3 when the mixing drum 3 is cleaned while being installed on the machine frame 2.

The vinegar receiving portion 136 may have a structure in which the upper opening surface of the container storage portion 137 is closed with a plate-shaped closing plate having the vinegar discharging portion 139 formed thereon.

In order to prepare sushi by mixing vinegar with rice with the vinegar mixer 1 having the above configuration, the drum lid 47 is first opened with the mixing drum 3 at the groove position shown in Fig. 8, The lid 47 is held by the lid holder 72. In this state, the vinegar is supplied to the vinegar receiving portion 136 and the rice is put into the drum main body 46. [

At this time, the mixing drum 3 is inclined forward and downward at the groove position, and the upper opening surface 124 of the drum main body 46 is inclined so as to move downward as it faces forward, .

Since the drum lid 47 is hinged to the drum main body 46, the vinegar and rice can be supplied into the drum main body 46 without removing the drum lid 47, By holding the drum lid 47 in the open state by the lid holder 72, the drum lid 47 is not required to be lifted up when the vinegar and rice are fed, and vinegar and rice can be easily supplied.

The vinegar and rice are supplied to the drum main body 46 and then the drum cover 47 is closed and the lock member 71 is locked and the start switch 17 provided on the operation panel 20 is pressed, 3 rotate in the rearward rotation direction R. [ 46, when the mixing drum 3 is rotated in the backward rotational direction R, the vinegar receiving portion 136 is rotated in the backward rotational direction R of the mixing drum 3, And passes over the front side of the support shafts 25L and 25R and moves above the drum supporting shafts 25L and 25R and passes over the drum supporting shafts 25L and 25R to move the drum supporting shafts 25L and 25R And moves to the rear side.

At this time, while the vinegar accommodating portion 136 is moved to the front surface of the drum supporting shafts 25L and 25R, the vinegar storage container 138 is a container having a front end opening shape, The vinegar storage vessel 138 does not leak the vinegar 152 because the vinegar storage vessel 138 is provided on the leading side in the direction R. Even if the vinegar storage container 138 moves directly to the front side of the drum support shafts 25L and 25R, the rice remains on the bottom 117b side of the main wall 117 of the drum main body 46, Since the portion 139 is clogged with rice, the discharge of the vinegar 152 is suppressed.

Thereafter, when the vinegar receiving portion 136 passes over the front surface of the drum supporting shafts 25L and 25R and the rice is lifted to some extent, the rice falls down by its own weight. When the rice falls by its own weight, the vinegar discharging portion 139 is opened and vinegar is discharged from the vinegar discharging portion 139. The vinegar 152 inside the vinegar storage vessel 138 is discharged from the vinegar storage vessel 138 from the rearward rotation position R rearward position which is the position directly above the drum support shafts 25L and 25R 25L, and 25R, the rice is dropped into the rice in the form of a shower, and vinegar is automatically and uniformly sprayed on the rice. Thereby, the vinegar can be uniformly mixed with the rice.

The rotation speed of the mixing drum 3 is controlled such that all of the vinegar 152 stored in the vinegar storage container 138 is dropped and discharged when the mixing drum 3 is rotated once for the first time. That is, when the vinegar 152 is dropped and supplied to the rice in the form of a shower, the speed of rotation of the mixing drum 3 from the home position (for example, 30 %). ≪ / RTI >

When the vinegar receiving portion 136 is moved by a predetermined amount beyond the position directly above the drum supporting shafts 25L and 25R (the state in which the vinegar receiving portion 136 is positioned just above the drum supporting shafts 25L and 25R) When the drum 3 is rotated by a predetermined angle, the mixing drum 3 rotates at a speed higher than that of the vinegar supply. The rotational speed of the mixing drum 3 after the vinegar supply may be a speed slightly lower than the rotational speed at the start (for example, 90% of the rotational speed at the start) or the same speed as the rotational speed at the start .

The rice is repeatedly lifted up to a predetermined height by the rotation of the mixing drum 3, and the rice is repelled by the rotation of the mixing drum 3 when the rice falls, and the rice is loosened (mixed with the rice balls) Vinegar is mixed in.

At this time, cooling air is supplied into the mixing drum 3 while the mixing drum 3 rotates in the rear rotation direction R, and the rice is cooled. When the predetermined time has elapsed, the rice (sushi) becomes stronger with the lapse of time, so that the mixing drum 3 is rotated in the backward rotation direction R while the rotational speed is decreased stepwise or stepwise in accordance with the elapsed time, .

47 (a), the lower drum lid restricting member 105 is moved in the direction of the rotation of the drum lid 47 in the rearward rotation direction R. On the other hand, when the mixing drum 3 is rotating in the rearward rotation direction R, The drum cover regulating member 105 on the upper side interferes with the projecting engaging portion 50 of the flange portion 49 of the drum cover 47 although the engaging portion 50 of the engaging portion 49 does not interfere with the projecting engaging portion 50 of the engaging portion 49. [ When the mixing drum 3 rotates in the backward rotation direction R so that the projecting engaging portion 50 contacts the upper drum lid regulating member 105, the drum lid regulating member 105 is brought into contact with the projecting engaging portion 50 And the upper portion of the swinging member 106 rocks forward in the direction of the swinging support shaft 108. As shown in Fig. The upper drum cover regulating member 105 is automatically released from the projecting engaging portion 50 of the drum cover 47 (the upper drum cover regulating member 105 is engaged with the projecting engaging portion 50 of the drum cover 47) (From the interference region 143 with the antenna 50).

47 (b), when the mixing drum 3 is rotating in the rearward rotation direction R, the unlocking member 104 is moved in the direction of the guide guide 88 ). When the mixing drum 3 rotates in the backward rotational direction R and the lock member 71 contacts the unlocking member 104, the unlocking member 104 is pressed against the lock member 71, 106 swings forward in the direction of the swing support shaft 108. As shown in Fig. Thereby, the lock releasing member 104 is automatically released from the lock member 71 (the lock releasing member 104 is retracted from the interference region 144 with the lock member 71).

The drum lid regulating member 105 is disengaged from the drum lid 47 by the pivotal member 106, the guide groove 111, the regulating pin 112 and the like and the unlocking member 104 is moved to the lock member 71, (The drum cover regulating member 105 is retracted from the interference region 143 with the drum cover 47 and the unlocking member 104 is retracted from the interference region 144 with the lock member 71) A relief means is constituted.

When the projecting engaging portion 50 is separated from the upper drum cover regulating member 105 and the lock member 71 is separated from the unlocking member 104, the swinging member 106 (the drum lid regulating member 105 And the unlocking member 104) return to their original positions.

When the rice is properly stirred, the mixing drum 3 is rotated several times in the backward rotational direction R, and then the rice is mixed with the rice in the steam-feeding process (with the blower 10 stopped) (The intermittent rotation of the mixing drum 3 in the backward rotation direction R) is performed in the cooling step (the intermittent rotation in the backward rotation direction R) The mixing drum 3 returns to the home position and stops. As a result, the sushi is uniformly mixed with rice vinegar.

After the mixing drum 3 returns to the home position, the automatic discharge operation of the sushi (planting material) automatically discharging the finished sushi automatically or by depressing the discharge switch 19 provided on the operation panel 20 .

This discharging operation is performed by rotating the mixing drum 3 in the forward rotational direction F from the groove position.

First, when the mixing drum 3 is rotated in the forward rotational direction F from the groove position shown in FIG. 48 (a), the lock member 71 is engaged with the unlocking member 104, , The lock of the lock member 71 is released.

49 (a), in the state in which the mixing drum 3 is positioned at the groove position, the guiding guide (not shown) of the locking member 71 88 are positioned above the unlocking member 104. At this time, the unlocking guide surface 88a of the guide guide 88 is inclined toward the front inclined downward.

49 (b), when the mixing drum 3 is rotated in the forward rotational direction F from this home position, the locking member 71 moves downward to move the lower end of the unlocking guide surface 88a The upper side contacts the unlocking member 104 from above. 49 (c) and (d), when the mixing drum 3 is rotated in the forward rotational direction F, the lock member 71 is moved downward relative to the unlocking member 104 The lock member 71 is forcibly moved to the front side by the unlocking member 104. As a result, Thereby, the lock member 71 swings in the direction of the pivot pin 98, the lock engaging portion 92 is disengaged from the lock retaining member 99, and the lock of the lock member 71 is released. At this time, the unlocking member 104 rotates relative to the unlocking guide surface 88a upward. Thereafter, the unlocking member 104 is separated from the unlocking guide surface 88a (guide guide 88) of the lock member 71 by rotating the mixing drum 3 in the forward rotational direction F. [

When the mixing drum 3 further rotates in the forward rotational direction F after the lock of the lock member 71 is released and the unlocking member 104 is separated from the unlocking guide surface 88a, The front lower end side of the projecting engaging portion 50 of the flange portion 49 of the drum lid 47 is in contact with the upper drum lid regulating member 105 from above and the drum lid 47 The swing motion to the side of the swing arm 46 is restricted.

When the drum main body 46 is further rotated in the forward rotational direction F in this state, as shown in Fig. 51, the projecting engaging portion 50 comes into contact with the drum cover regulating member 105 on the lower side, 47 are restricted from swinging toward the drum main body 46 side and the drum main body 46 is prevented from swinging in the rearward direction as the upper opening surface 124 is directed downward and the upper opening surface 124 is directed downward (Planting / discharging posture) in a slanting manner, and the drum main body 46 is once stopped at this sushi discharging posture.

On the other hand, the sushi in the drum main body 46 is gradually moved from the beginning of the upper opening surface 124 of the drum main body 46 to the lower side until the drum main body 46 becomes the sushi- And when the drum main body 46 reaches the sushi delivery position, almost all of the sushi is dropped and discharged to the sushi storage box 39 (accordingly, when the drum main body 46 is in the sushi delivery position, The inclination angle of the sushi support surface 123 with respect to the horizontal is larger than the angle of repose).

After the drum main body 46 is stopped for a predetermined time in the sushi discharge position (when sushi is discharged), the drum main body 46 rotates in the backward rotation direction R and returns to the home position.

When the mixing drum 3 is returned to the home position after the sushi is discharged, the guide 88 of the lock member 71 comes into contact with the unlocking member 104. At this time, Shaped corner portion 88d is brought into contact with the lock release member 104 and the lock release member 104 is moved from the front face 88b or the upper face 88c of the guide guide to the lock release guide face 88a So that the guide guide 88 of the lock member 71 is not caught by the unlocking member 104. As a result,

In the vinegar mixer 1 having the above-described configuration, the drum lid 47 of the mixing drum 3 is provided with the drum rotation shaft center X as the center and on the drum side Swelling parts 122F and 122R which swell outward beyond the arc W contacting the upper surface of the inner surface of the mixing drum 3 and the drum body 46 of the mixing drum 3 on the leading side in the backward rotation direction R Swelling portions 119F and 119R are provided on the trailing side to swell outward beyond the arc V which is in contact with the lower portion of the inner surface of the drum main body 46 with the drum rotation axis X as the center. By providing the bulging portions 119F, 119R, 122F, and 122R, the space ratio inside the mixing drum 3 can be increased.

When the rice is stirred by rotating the mixing drum 3 in the backward rotational direction R, the rice is rotated together with the mixing drum 3 to be lifted up. When the rice is lifted to some extent, The rice can be lifted up to a high position and dropped from the high position into the stirring rod 129 by installing the bulging portions 119F, 119R, 122F and 122R.

The stirring performance can be improved by increasing the space ratio inside the mixing drum 3 and by dropping the rice from the high position into the stirring rod 129. [

The inner surface of the front portion 117a of the peripheral wall 117 of the drum main body 46 becomes the sushi support surface 123 at the time of rice discharge when the drum main body 46 is in the sushi discharge posture, The surface 123 is formed so as to be wider from the bottom 117b side of the drum main body 46 toward the upper opening toward the end of the upper opening so that the sushi support surface The angle of inclination with respect to the horizontal direction of the cooking cavity 123 is increased, so that the dischargeability of the rice can be improved.

The sushi can be brought closer to the direction away from the stirring rod 129 by the swollen portion 119F on the leading side of the rearward rotational direction R of the drum main body 46 at the time of sushi discharge, It is possible to reduce the rate at which sushi is caught in the stirring rod 129, thereby contributing to an improvement in sushi discharge performance.

The inner surface of the rear portion 117d of the main wall 117 of the drum main body 46 is made to be the same as the sushi supporting surface 123 from the bottom 117b side of the main wall 117 of the drum main body 46, The length of the side of the lower opening surface 133 of the drum lid 47 becomes longer and the hinge shaft 79 is displaced to the rear side.

In this case, the position of the lower end of the drum lid 47 is lowered when the drum main body 46 is set in the sushi discharge position, as indicated by the imaginary line in Fig. Since the sushi storage box 39 is disposed below the mixing drum 3, if the position of the lower end 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 substantially flush with the upper opening surface 124 of the drum main body 46 And is formed so as to be perpendicular to the front and rear lengths H1 of the front side from the drum rotation axis X of the upper opening surface 124 of the drum body 46, The hinge fulcrum of the drum lid 47 can be brought closer to the front side and the front and rear lengths H2 of the drum lid 47 can be reduced. It is possible to suppress the lowering of the position of the lower end of the drum lid 47 when the drum main body 46 is set to the sushi discharge posture and to reduce the height of the mixing drum 3 .

In this embodiment, by rotating the drum main body 46 in the forward rotational direction F, the lock member 71 is engaged with the lock releasing member 104 so that the lock of the lock member 71 is automatically The lock member 71 can be unlocked easily.

When the drum main body 46 is further rotated in the forward rotational direction F after releasing the lock of the lock member 71, the drum main body 46 is rotated in a direction in which the upper opening surface 124 faces downward The sushi in the drum main body 46 is dropped and discharged so that the drum body 46 is closed with the drum cover 47 having no opening. It can be automatically taken out from the drum 3, which is very convenient. In addition, the sushi can be taken out of the drum main body 46 without removing the drum cover 47. [

The drum lid regulating member 105 engages with the drum lid 47 to restrict the drum lid 47 from oscillating toward the drum main body 46 when the drum main body 46 is in the sushi discharge posture , The drum cover (47) does not interfere with the sushi discharge, so that the sushi can be easily discharged.
