Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooling air discharge device for a rice / vinegar mixing device in which a mixture of rice, vinegar and other seasonings or ingredients is placed in a rotary container and mixed.

[0002]

2. Description of the Related Art Conventionally, a mixing device used for making sushi rice by mixing vinegar with freshly cooked rice includes a rotating container for putting the rice and vinegar and rotating the same, as well as a feeding cylinder on the axis of rotation. It is equipped with a cooling fan that forcibly supplies the cooling air into the rotating container via the cooling air to cool the rice and to let the moisture out of the rotating container with the cooling air to prevent the stickiness of the rice. I have to.

As a form of discharging the cooling air supplied into the rotary container to the outside, conventionally, an exhaust pipe is provided on the rotation axis of the rotary container so as to face the feed cylinder, and is exhausted to the outside from the exhaust pipe. And a type in which an exhaust hole is formed in the lid of the rotating container and the exhaust hole is allowed to escape.

[0004]

In the conventional discharge type,
There are the following problems. That is, in the former exhaust type, since the sending cylinder and the exhaust cylinder are opposed to each other on the rotation axis, the cooling air supplied from the exhaust cylinder into the rotary container is directly passed through and is discharged from the exhaust cylinder to the outside. It is difficult to circulate in the rotating container, and there is a problem that the cooling effect of rice is significantly reduced.

Therefore, from the viewpoint of cooling effect, the latter discharge type is naturally preferable. However, in the conventional latter discharge method, a simple exhaust hole is formed in the lid, and the cooled cooling air in the rotary container is allowed to escape to the outside from the exhaust hole. Therefore, if the cooling air is supplied to the inside of the rotating container to cool it while the rotating container is rotating, hot and humid air containing a large amount of moisture is discharged from the exhaust hole of the lid of the rotating container to the surroundings. Since it is discharged, the working environment is significantly deteriorated by the hot and humid air. .

On the other hand, if a method is adopted in which cooling air is supplied while the rotary container is stopped to cool it, the rice does not move in the rotary container, so the cooling efficiency is poor and it takes time to cool the rice. Needless to say, high-temperature and high-humidity air that contains water may be lodged inside the rotating container, causing stickiness of the rice and other quality problems.

In view of the above-mentioned conventional problems, the present invention can always discharge the cooled cooling air to the outside from a fixed location, even though the cooled cooling air is discharged from the exhaust hole of the lid. An object of the present invention is to provide a cooling air discharge device in a mixing device of rice, vinegar, etc. which can be cooled significantly and can be efficiently cooled in a short time without stickiness of the rice.

[0008]

The present invention according to claim 2 provides the invention according to claim 1.
In the invention described in (1), the relay passage 60 is provided in the container mount 23 to which the rotary container 3 is detachably attached.

[0010]

When the mixture S such as vinegar is mixed with the rice M, after the rice M and the mixture S such as vinegar are put in the rotary container 3,
Rotate container 3 to mix. At this time, if necessary, the cooling means 5 supplies cooling air into the rotary container 3 to cool the rice M. The cooling air in the rotary container 3 is discharged to the outside from the exhaust hole 16 of the lid 13 through the guide passage 63, the relay passage 60, and the discharge passage 65. Therefore, even if the cooling air is supplied while the rotating container 3 is rotating to cool the rice M, the cooling air after the cooling is not discharged to the periphery of the rotating container 3.

It is fixed to the side wall 8a on the 67 side, and another exhaust duct 68 is connected to the outer end of the exhaust pipe 66.

Next, the operation of the above configuration will be described with reference to the time chart of FIG. Usually a rotating container
3 is stopped at the closing position X as shown by the solid line in FIG. Therefore, when making sushi rice by mixing vinegar S with rice M, first remove the lid 13 and put the required amount of cooked rice M into the rotary container 3 and add the required amount of vinegar S. After the addition, the lid 13 is attached to close the opening 10 of the rotary container 3. At this time, the guide passage 63 of the lid 13 is attached to the container mount 23.
To the relay passage 60 of.

Next, when the start switch is pushed, the control device operates and the drive motor 29 is started, so that the winding transmission mechanism is activated.
30, horizontal axis 2, rotary container 3 is horizontal axis 2 via container mount 23
Around a Rotate in the direction of the arrow. Then, when the rotary container 3 rotates, the rice M in the rotary container 3 relatively moves in the direction opposite to the arrow a direction along with the rotation, whereby the vinegar S is mixed with the rice M.

Each time the rotary container 3 makes one rotation, the cam plate 34 activates the closing position detecting switch 36. If the rotating container 3 rotates by the set number, the drive motor 29 is activated when the closing position detecting switch 36 operates. Stops and the rotary container 3 stops at the feeding position X. Then, the control device works and the cooling means 5
With the start of supplying the cooling air into the rotary container 3 at the same time, while stopping the rotary container 3 at the feeding position X for a certain time (for example, about 15 seconds) every time the rotary container 3 makes one rotation,
The rotating container 3 is intermittently rotated by the rotation driving means 4 to cool the rice M.

During this cooling, the cooling fan 38 drives by the cooling fan motor 41, so that the cooling fan 38 sucks external air from the outside of the support frame 8 through the air suction hole 44, and the vertical transfer cylinder 39 and the connection box. It is supplied as cooling air into the rotary container 3 from the tip of the cylindrical horizontal axis 2 via 40. Horizontal axis 2
The cooling air supplied from the rotating container 3 is guided by the guide plate 28.
The rice M is cooled while being guided to the inner surface side of the rice and circulating through the inner surface of the rotary container 3 and the surface of the rice M.

After cooling, the high-temperature and high-humidity cooling air containing water enters the exhaust pipe 17 from the perforated pipe portion 19 of the exhaust pipe 17, and the lid body
It flows through the exhaust holes 16 of 13 toward the guide passage 63 side. Then, this air is sent from the relay passage 60 of the container mount 23 through the discharge passage 65 to the exhaust duct 68, and the exhaust duct 68.
Is discharged from. By doing so, even if the cooling air is supplied into the rotating container 3 to cool the rice M while the rotating container 3 is rotating, the air after cooling is discharged from the exhaust hole 16 of the lid 13 in the rotating state. It will not be discharged directly to the surroundings. Therefore, the working environment can be significantly improved as compared with the case where hot and humid air is discharged.

Further, even if the rotary container 3 is cooled during its rotation, no problem occurs due to the air discharged after cooling, so the amount of cooling air supplied, etc. can be determined in consideration of the cooling effect of the rice M. it can. Therefore, the rice M can be effectively cooled,
There is no stickiness of the rice M after cooling, and the quality of the rice M is significantly improved.

Moreover, since the discharge passage 65 is provided in the fixed side support frame 8, the air discharged from the discharge passage 65 can be easily guided to the outside through the exhaust duct 68, and the subsequent processing can be easily performed. Further, a relay passage 60 is provided in the container mounting base 23 which rotates integrally with the rotary container 3, and the relay passage 60 and the fixed side discharge passage 65 are communicated with each other through the through hole 63 on the rotation center side of the rotary container 3. Therefore, the communication structure of both passages 60, 65 can be simplified.

When the rotary container 3 is rotated a set number of times while the cooling air is being supplied, the cooling fan motor 41 and the drive motor 29 are stopped when the closing position detection switch 36 is activated,
The rotating container 3 stops at the feeding position X and the cooling is completed. Next, the lid 13 of the rotary container 3 is removed, the opening 10 is opened, the rice extracting container 9 is placed on the dolly 7 of the base 1, and then the extraction switch is pressed. Then, the drive motor 29 rotates the rotary container 3 from the loading position X to the removal position Y, and the cam plate
When the take-out position detection switch 37 is actuated by 35, the rotary container 3 stops at the take-out position Y.

At this take-out position Y, as shown by the chain double-dashed line in FIG. 5, since the opening 10 of the rotary container 3 is directed obliquely downward, the rice M in the rotary container 3 is placed in this state. 9
Take it out. After taking out the rice M, the return switch 59 is pushed and the rotary container 3 is rotated to return to the loading position X. When the closing position detection switch 36 operates, the rotary container 3 is stopped at the closing position X. With this, as shown in FIG. 8, a series of vinegar combining steps from the addition of the rice M and the vinegar S to the mixing, cooling and taking out is completed.

When the rotary container 3 is washed while it is still attached to the container mount 23 of the horizontal axis 2, water may enter 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, or to put water into the rotary container 3 to cover the lid 13. After closing, it is also possible to wash with water while rotating the rotary container 3. Further, since the water that has entered the junction box 40 is drained to the outside through the drain port 46 and the drain pipe 47, the water does not accumulate in the junction box 40. The drain pipe 47 has a trap portion 48 that bends in a U shape.
It is always sealed with 48 water. For this reason, junction box 40
Although the drain pipe 47 is connected to
It is very hygienic as there is no dust, insects, etc. in the connection box 40 after passing through.

Although the embodiment has been described above, other than that, the following configuration may be adopted. The rotary container 3 may have a lid 13 that can be opened and closed, and the shape thereof may be a cylindrical shape with a bottom or a ball shape. Further, the rotary container 3 is not limited to the one that rotates around the horizontal axis 2, but may be the one that rotates around the tilt axis, the one that swings around a single point, or the like. Further, the guide passage 63 of the lid 13
Can also be constructed by bending a pipe. It is sufficient that the relay passage 60 is provided so as to rotate together with the rotary container 3, and may be integrally provided on the side surface of the rotary container 3, for example. However, providing the relay passage 60 in the container mount 23 simplifies the structure of the rotating container 3.

Also when the relay passage 60 is provided in the container mount 23, the container mount 23 is formed by a plate material having a U-shaped cross section, and a member having a narrow C-shaped cross section is attached to the center thereof. May be. Further, the discharge passage 65 may use the inside of the cylindrical horizontal shaft 2. In this case, the sending cylinder may be provided separately from the horizontal axis 2 or may be inserted inside the horizontal axis 2. Further, in the embodiment, the case where the mixture is vinegar S and this is mixed with the rice M is illustrated, but the mixture may be various other seasonings, or may be a component for mixed rice.

The lid 13 is provided with a guide passage 63 for communicating 16 with one end of the relay passage 60, and a fixed discharge passage 65 is provided for communicating with the other end of the relay passage 60 so as to be relatively rotatable. The cooling air after cooling the rice M inside is exhausted through the exhaust hole 16 of the lid body 13.
Despite being discharged from the cooling air, the cooling air can always be discharged to the outside from the discharge passage 65 at a fixed location. Therefore, even if the cooling air is supplied into the rotary container 3 to cool the rice M while the rotary container 3 is rotating, the hot and humid air is not discharged from the rotating rotary container 3 to the surroundings. The working environment can be significantly improved. Further, even if the rotary container 3 is cooled during rotation, no problem occurs due to the discharged air, so the amount of cooling air supplied and the like can be determined in consideration of the cooling effect of the rice M. Therefore, the cooked rice M can be effectively cooled in a short time, the cooked cooked rice M does not have stickiness, and the quality of the cooked rice M is significantly improved. Moreover, since the discharge passage 65 communicates with the other end side of the relay passage 60 so as to be rotatable relative to each other, and the discharge location of the cooling air can be fixedly fixed, the air discharged from the discharge passage 65 is also discharged by the discharge duct 68. Subsequent processing such as guiding to the outside can be easily performed. Further, according to the invention described in claim 2, in the invention described in claim 1, since the relay passage 60 is provided in the container mount 23 to which the rotary container 3 is detachably attached,
Compared with the case where the relay passage 60 is provided on the rotary container 3 side, there is an advantage that the structure on the rotary container 3 side can be simplified.
