After the rice is cooked, the rice cooker 2 is carried out of the steam outlet 12 by the carry-out means 29 to the outside of the steaming chamber 12 and sent to the next step.

Although a part of the upper surface of the steaming chamber 12 (for example, a half or more portion) is covered by an inclined ceiling plate 22 that slopes upward toward the front, the other part of the upper surface of the steaming chamber 12 remains. The portion (on the outlet side of the hook) is opened upward by the outlet 27.

The conveying means 15 has a pair of left and right chains 31 which form an endless shape, and each of these chains 31 is hung on a sprocket 32 which is a front and rear rotating body rotated by power from a drive motor (not shown). ing. Further, a plurality of carriers (not shown) for supporting the handle portion 7 of the cooker main body 4 and for transporting the rice cooker 2 are attached to each chain 31 at intervals.

The transport by the transport means 15 is not limited to continuous transport in which the plurality of rice cookers 2 continuously move in the transport direction, but tact transport in which the plurality of rice cookers 2 intermittently move in the transport direction. But it's okay.

The heating means 16 is composed of, for example, a plurality of gas burner units (press burner Assy) 36 that are arranged side by side in the transport direction in the state of being close to each other at the bottom of the heating chamber 11.

As shown in FIGS. 3 and 4, the gas burner unit 36 has a plurality of rows (for example, eight rows) of burners (press burners) 37 that form a longitudinal shape along the conveyance direction. A plurality of gas ejection ports 38 that open toward the front are formed.

Further, the gas burner unit 36 has an outside air shielding plate 39 having a longitudinal shape in the transport direction, which is located between the two adjacent burners 37 facing each other apart from each other, and by this outside air shielding plate 39, the space between the both burners 37 is substantially formed.

Outside air) flows into the heating chamber 11 as secondary air and is supplied to the vicinity of the gas ejection port 38 (see FIG. 4). The gap 40 is formed between the vertical plate portion 39b of the outside air shielding plate 39 and the side surface of the burner 37.

Further, a fire transfer plate 35 having a long shape in the left-right direction which is a direction orthogonal to the transport direction is attached to the plurality of outside air shielding plates 39.

Each shield plate 18 is removably attached to the shield plate attachment portion 41 of the apparatus main body 13 by a fixture 43 such as a screw. In addition, each shield plate 18 has a horizontal posture at least along the transport direction and a slanting up-tilt posture (rearward) that is slanted upward in the transport direction (rearward) which is the moving direction of the rice cooker 2 in the heating chamber 11. It is possible to change the posture between the upward inclination posture) and the downward inclination posture (front upward inclination posture) in which the rice cooker 2 moves in the heating chamber 11 in the conveying direction (rearward). There is. That is, the plurality of shield plates 18 can adjust the flow of hot air from the heating chamber 11 to the steaming chamber 12 based on at least the posture change with respect to the apparatus body 13.

In addition, for example, in the example shown in FIG. 1, all of the three shield plates (partition plates) 18 are in the upward inclined posture. Therefore, among the shielding plates 18 adjacent to each other, an opening 42 for passing hot air exists between the rear end of the shielding plate 18 located on the front side and the front end of the shielding plate 18 located on the rear side. doing.

Each of the three shield plates 18 has, for example, the same size, and is divided into two left and right plate members 18a and 18b for facilitating the attachment/detachment work of the shield plate 18 as shown in FIG. It is configured. Therefore, when removing the shielding plate 18, the plate members 18a and 18b are removed one by one and taken out of the apparatus main body 13. Although not shown, the shielding plate 18 may be composed of a single plate member.

Each hanging wall 19 is detachably attached to the hanging wall attaching portion 46 of the apparatus main body 13 by an attaching tool 44 such as a screw. The hanging wall mounting portions 46 are provided on the lower surface of the ceiling plate 22 at intervals.

Further, the lower end portion of each hanging wall 19 is formed in a shape corresponding to the lid body 5 of the rice cooker 2. That is, the lower end portion of the hanging wall 19 includes a horizontal lower end portion 47 located at the center in the left-right direction, one lower end portion 48 on the left side located on the upper right side, and the other lower end portion 48 on the right side located on the other side. It is composed of the lower end portion 49. Then, the handle portion 6 of the lid body 5 of the rice cooker 2 passes under the horizontal lower end portion 47 of the lower end portion of the hanging wall 19.

Each of the three hanging walls 19 is made of, for example, a single plate member having a different size, and the one located closer to the front side is larger. Although not shown, the hanging wall 19 may be configured by a plate member that is divided into two left and right parts.

Next, the operation of the continuous rice cooker 1 will be described.

The rice cooker 2 containing rice and water before being cooked is supplied to the heating chamber 11 through the oven inlet 25 and heated by the hot air (combustion heat) generated by the gas combustion of the burner 37 of the heating means 16 in the heating chamber 11. It

At this time, since the upper surface of the heating chamber 11 is covered with the shielding plate 18, the hot air stays in the heating chamber 11 without directly rising to the steaming chamber 12, and the hot air is passed from the upper part of the rice cooker 2 to the side. It is heated efficiently. Further, since the lower surface of the heating chamber 11 is covered by the burner 37 and the outside air shielding plate 39, no extra outside air other than the secondary air necessary for gas combustion enters, and the bottom of the rice cooker 2 moves to the side. Efficiently heated by hot air. In this way, the entire rice cooker 2 is heated in the heating chamber 11 with good thermal efficiency.

After that, the rice cooker 2 is transported from the heating chamber 11 to the steaming chamber 12 by the transporting means 15, and is steamed while being heated by the hot air from the heating chamber 11 in the steaming chamber 12.

That is, the hot air after heating the rice cooker 2 in the heating chamber 11 flows into the steaming chamber 12 from the communication opening (rear part of the apparatus main body 13) 50 that connects the heating chamber 11 and the steaming chamber 12 and is shielded. It is guided by the plate 18 and dispersed from a plurality of openings (two openings in the example shown in FIG. 1) 42 and flows into the steaming chamber 12. At this time, due to the hot air flowing into the steaming chamber 12 through the communication opening 50 and the plurality of openings 42, the rice cooker 2 located above the openings 42 is directly exposed to the flow of hot air. It is also heated from below. The hot air that rises from the heating chamber 11 and flows into the steaming chamber 12 is due to the fact that the outside air shielding plate 39 is provided between the adjacent burners 37 and the gas is burned by the minimum required secondary air. Since it is not a mixture of a large amount of air, it does not cause an increase in the flow of current one after another as compared with the case where the outside air shielding plate 39 is not provided.

Then, the steaming process is performed while the rice cooker 2 is heated by the hot air flowing into the steaming chamber 12.

At this time, since the hanging wall 19 is provided in the upper part of the steaming chamber 12, the hot air flowing toward the discharge port 27 side along the inclined ceiling plate 22 has a hanging wall (in the example shown in FIG. 1, The rice cooker 2 located near the lower part of the hanging wall 19 is efficiently heated by the hot air that has stayed once. In particular, the hot air accumulated by the hanging wall 19 passes through the lower end of the hanging wall 19 to generate a flow toward the discharge port 27 side, and the rice cooker 2 (front side of the hanging wall 19) corresponding to this flow It is more heated. That is, during this steaming, the amount of heat required for steaming is efficiently added to the rice cooker 2 at the required position.

The hot air after heating the rice cooker 2 in the steaming chamber 12 flows forward and is discharged from the discharge port 27 to the outside of the steaming chamber 12.

In this way, the steaming process is performed, and the rice cooker 2 in which the rice in the kettle has been cooked to a desired finished state is carried out of the steam outlet 12 from the kettle outlet 26 and sent to the next step.

Here, in this continuous rice cooker 1, the rice in the rice cooker 2 is cooked to a desired finished state by adjusting the flow of hot air (combustion heat) in the steaming chamber 12, that is, for example, for the use of cooked rice. It is possible to change the mounting pattern of the shielding plate 18 and the hanging wall 19 so that cooked rice having a desired hardness and stickiness can be obtained.

That is, in the example shown in FIG. 1, the three shield plates 18 and the three hanging walls 19 are attached to the apparatus main body 13, and all the three shield plates 18 are in the rearward upward inclination posture. However, other than this mounting pattern, for example, the mounting pattern shown in FIGS. 5 to 8 can be changed.

In the example shown in FIG. 5, the three shield plates 18 and the three hanging walls 19 are attached to the apparatus main body 13, and the front shield plate 18 is in a rearwardly inclined posture, as shown in FIG. Same as the example. However, in the example shown in FIG. 5, the shield plate 18 in the center is in a horizontal posture, and the shield plate 18 in the rear side is in a forward ascending posture, so that hot air is blown from the central portion of the heating chamber 11 to the latter half of the steaming chamber 12. Many of them are directed to flow.

Further, in the example shown in FIG. 6, the rear shield plate 18 is removed from the apparatus main body 13 to guide the hot air from the latter half of the heating chamber 11 to the entire first half of the steaming chamber 12.

Further, in the example shown in FIG. 7, the two hanging walls 19 are removed from the apparatus main body 13, the central and rear shielding plates 18 are in a horizontal posture, and the thermal efficiency in the heating chamber 11 is emphasized. ..

Further, in the example shown in FIG. 8, the two hanging walls 19 are removed from the apparatus main body 13, the central shielding plate 18 is in a horizontal posture, and in the heating chamber 11, the thermal efficiency by the hot air is emphasized and the steaming chamber 12 has Most of the hot air was introduced to the first half of the steaming process. Further, in this example, although the front shield plate 18 is in the rearward upward inclination posture, its inclination angle β is smaller than the normal inclination angle α of the rear shield plate 18. That is, the inclination angle of the shielding plate 18 can be adjusted to an arbitrary angle within a predetermined range (in the space between the upper and lower rice cookers).

In addition to the mounting patterns shown in FIG. 1 and FIGS. 5 to 8, although not shown, for example, a mounting pattern using only one shield plate 18 or a mounting pattern in which all shield plates 18 are removed and the shield plate 18 is not used. It is also possible to remove all the hanging walls 19 and change to a mounting pattern that does not use the hanging walls 19.

Further, according to the continuous rice cooker 1, hot air is caused to flow from the heating chamber 11 to any part of the steaming chamber 12 by changing the posture of the shielding plate 18 (changing the angle with respect to the horizontal direction) and detaching the shielding plate 18 (changing the number of sheets). Since it is possible to adjust whether to heat the rice cooker 2 by applying heat, an appropriate steaming process can be performed in the steaming chamber 12, so that the rice in the rice cooker 2 can be cooked to a desired finished state and desired. Hard and sticky rice is obtained.

Further, by attaching/detaching the hanging wall 19 (changing the number of sheets), it is possible to adjust in which part of the steaming chamber 12 hot air should be retained and heat should be applied to the rice cooker 2, so that more appropriate steaming in the steaming chamber 12 is possible. It can be processed.

Further, since the heating means 16 has the burners 37 facing each other and separated from each other and the outside air shielding plate 39 located between the both burners 37, only the minimum amount of outside air required for gas combustion of the burners 37 is supplied to the secondary air. As a result, the rice cooker 2 can be efficiently heated in the heating chamber 11.

Note that the configuration is not limited to the configuration in which each of the three shield plates 18 and the hanging wall 19 is provided, and for example, a configuration in which four or more sheets are provided may be used.

Further, for example, the hanging wall 19 may be provided on the apparatus main body 13 so that the posture can be changed. That is, the inclination angle of the hanging wall 19 with respect to the vertical direction may be adjusted within a predetermined range.

Further, for example, the shield plate 18 may have a position adjustable in the front-back direction, and the hanging wall 19 may have a position adjustable in the front-back direction.

Further, for example, by providing a hot air passage portion (for example, a punching hole, a louver hole, a notch, etc.) in a part of the shielding plate 18, the position where the hot air from the heating chamber 11 flows into the steaming chamber 12 can be freely set, It may be made to flow into the steaming chamber 12 through a hot air passage portion provided at a position to be made to flow. Further, an opening/closing member capable of opening/closing the hot air passage portion may be provided.

Further, in order to adjust the retention of hot air in the steaming chamber 12, for example, a closing plate that closes at least a part of the outlet 27 of the apparatus body 13 may be detachably attached to the apparatus body 13.
