SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem

However, the hot air flowing into the first cooking chamber heats the bottom of the rice cooker in the first cooking chamber, but it also flows between the rice cookers arranged in series in the conveying direction of the first cooking chamber, and then directly circulates to the top (inner ceiling) of the second cooking chamber. As such, the hot air of the heating chamber may not uniformly heat the entirety of each of the rice cookers transferred in the first and second cooking chambers, so that the rice in the rice cookers in the respective cooking chambers cannot be uniformly cooked.

In view of the above problem, the utility model provides a continuous cooking device, the device can utilize the steam of heating chamber to carry out the bulk heating to the rice cooker of the indoor conveying of second cooking of first cooking chamber and top more effectively to make the rice in the rice cooker can obtain more even cooking.

Means for solving the problems

In view of the above, the present invention provides a continuous cooking apparatus for cooking rice in a rice pot by heating the rice pot which is continuously conveyed. The continuous rice cooking apparatus at least comprises: a device body composed of an inlet into which a rice pot enters, a cooking chamber for cooking rice in the rice pot entering from the inlet, and an outlet from which the rice pot leaves from the cooking chamber; a conveying device having a first conveying unit, a second conveying unit and a third conveying unit, the first conveying unit continuously conveying the rice cookers from the inlet toward the outlet, the second conveying unit being provided above the first conveying unit and continuously conveying the rice cookers conveyed by the first conveying unit from the outlet toward the inlet, the third conveying unit being provided above the second conveying unit and continuously conveying the rice cookers conveyed by the second conveying unit from the inlet toward the outlet; and a heating device provided below the cooking chamber to heat the rice pot in the cooking chamber. The brewing chamber comprises: a heating chamber provided above the heating device, the heating chamber heating the rice in the rice pot transferred by the first transfer unit by the heating device; a first cooking chamber provided above the heating chamber so as to communicate with the heating chamber, the first cooking chamber cooking rice in the rice pot while the rice pot heated by the heating chamber is transferred by the second transfer unit; and a second cooking chamber provided above the first cooking chamber in such a manner as to communicate with the first cooking chamber, the second cooking chamber cooking rice in the rice pot while the rice pot heated by the first cooking chamber is transferred by the third transfer unit. A hot air guide structure formed with a ventilating portion through which hot air of the heating chamber passes is provided between the heating chamber and the first cooking chamber, and the ventilating portion allows the hot air to pass in such a manner as to move toward the bottom of the rice pot conveyed by the second conveying unit. And a partition plate for separating the rice pot in the first cooking chamber from the rice pot in the second cooking chamber is arranged between the first cooking chamber and the second cooking chamber. A gap for the hot air of the first cooking chamber to flow into the second cooking chamber is formed between the sidewall of the cooking chamber formed along the conveying direction of the rice cooker and the partition.

Effect of the utility model

According to the utility model discloses, owing to be equipped with the baffle that separates the rice pot in the first cooking chamber and the second cooking chamber, consequently under the effect that blocks of this baffle, the steam that partly flows in of ventilating through steam guide structure can't directly follow the situation and flow into the second cooking chamber from first cooking chamber. Thus, the hot air flowing into the first cooking chamber through the vent part stays temporarily in the first cooking chamber, thereby filling the first cooking chamber. In the first cooking chamber, the temperature in the first cooking chamber is made uniform by the hot air filled therein due to staying, so that the whole of the rice pot transferred into the first cooking chamber can be uniformly heated.

The hot air further flowing in through the ventilating part of the heating chamber flows toward the bottom of the rice pot conveyed into the first cooking chamber, then flows upward along the periphery of the rice pot, and further flows into the second cooking chamber through the gap between the side wall of the cooking chamber and the partition plate. In this manner, in the first cooking chamber, since the hot air flows from the bottom of the rice pot along its circumference, the rice pot transferred into the first cooking chamber can be heated more uniformly.

In this way, in the second cooking chamber, since the hot air in the heating chamber is directly raised along the heating direction, the rice pot in the second cooking chamber is not preferentially heated, and therefore, the whole rice pot conveyed therein can be uniformly heated by the first cooking chamber and the second cooking chamber.

second cooking chambers

15, 16 in this order by rotationally driving the second driving mechanism 22 a.

The heating means 30 is an infrared burner provided below the cooking chamber 12, and heats the pots P, P … … continuously conveyed by the first conveying unit 21 of the conveying means 20 in the cooking chamber 12. Since the infrared burner is configured not to use secondary intake air, it is disposed to face the bottom of the heating chamber 14 described below as shown in fig. 2. In the present embodiment, the heating means 30 includes a first burner 31 for heating the bottom Pb of the rice pot P in conveyance, and a pair of

second burners

32, 32 for heating the left and right sides of the rice pot P.

The plurality of first and

second burners

31, 32 are arranged side by side in the conveying direction S of the rice pot P and are composed of an air supply pipe 34 for supplying a mixture of gas and air, a ceramic plate 35, and the like. When the heating means 30 heats the rice pot P, the mixed gas supplied from the gas supply pipe 34 is delivered to the ceramic plate 35 and burned on the surface thereof. In addition, the adjustment of the heating condition of the rice pot P is carried out by controlling the partial combustion condition of the first and

second burners

31, 32 and stopping the combustion.

Wherein the cooking chamber 12 of the device body 10 includes a heating chamber 14, a first cooking chamber 15, and a second cooking chamber 16. The heating chamber 14 is formed on the heating device 30, and is a portion where the heating device 30 heats the rice in the rice pot P conveyed by the first conveying unit 21. The first cooking chamber 15 is formed above the heating chamber 14 so as to communicate with the heating chamber 14. The first cooking chamber 15 is a portion for cooking rice in the rice pot P while transferring the rice pot P heated by the heating chamber 14 by the second transfer unit 22.

Between the heating chamber 14 and the first cooking chamber 15, there is provided a hot air guide structure 40 on which a ventilating portion 41 through which hot air H of the heating chamber 14 passes is formed so that the hot air H moves toward the bottom Pb of the rice pot P conveyed by the second conveying unit 22. The hot air guide structure 40 extends in the rice cooker transferring direction S and has an inclined surface at a side surface of the heating chamber 14 in order to flow the hot air toward the ventilating portion 41. The hot air guide structure 40 is formed by filling a heat insulating material (not shown) in a covering (not shown). In this way, the internal space of the heating chamber 14 is referred to as an insulating space, so that rice immersed in water in the rice pot P can be cooked efficiently with the heating heat of the heating device 30.

The second cooking chamber 16 is formed above the first cooking chamber 15 in such a manner as to communicate with the first cooking chamber 15. The second cooking chamber 16 is a portion where the rice in the rice pot P heated by the first cooking chamber 15 is cooked while the rice pot P is conveyed by the third conveying unit 23. Further, a hot air discharge port 61 is formed at the center in the width direction (direction perpendicular to the conveying direction S) of the second cooking chamber 16, and the hot air discharge port 61 communicates with the exhaust fan 60. The second cooking chamber 16 is provided at the top thereof with a temperature sensor (not shown) for discharging hot air in the second cooking chamber 16 to the upper side of the rice cooking system 1 by driving the exhaust fan 60 through a control unit (not shown) when the temperature of the second cooking chamber reaches a predetermined temperature or higher.

In order to separate the rice pot P in the first cooking chamber 15 from the rice pot P in the second cooking chamber 16, a partition plate 50 made of, for example, stainless steel or the like is provided between the first cooking chamber 15 and the second cooking chamber 16. Wherein a gap C through which hot air flows from the first cooking chamber 15 into the second cooking chamber 16 is formed between the partition 50 and the side wall 12a of the cooking chamber 12 formed in the transporting direction S of the rice pot P.

In the present embodiment, in a state where the partition plate 50 is provided between the first cooking chamber 15 and the second cooking chamber 16, a concave groove 57 opening toward the first cooking chamber 15 is formed on the first cooking chamber 15 side of the partition plate 50.

Specifically, the partition plate 50 is supported by a plurality of

support beams

12b, 12b … … provided across the

opposite side walls

12a, 12a of the cooking chamber 12 at intervals L in the conveying direction S of the rice pot P.

More specifically, as shown in fig. 3 (a) and (b), the partition 50 is formed with a top plate 51 and a bent structure 52 bent from an edge of the top plate 51 toward the first cooking chamber 15 side. The bent structure 52 has a notch 53 formed therein for insertion of the support beam 12b so that the support beam 12b is in contact with the top plate 51 in a state where the partition plate 50 is supported by the support beams 12b, 12 b. Notches 53 are formed in portions of each bending structure 52 on both sides in the conveying direction. With this structure, the recess 57 opened toward the first cooking chamber 15 side forms a space surrounded by the adjacent pair of

support beams

12b, 12b and the bent structure 52 of the partition plate 50.

Further, the partition 50 is divided into two parts in a direction (width direction) perpendicular to the conveying direction S of the rice pot P. Specifically, two

sub-plates

50a, 50a arranged in parallel in the width direction are used as the partition plate 50. Each of the partial plates 50a is further formed at mutually adjacent edges thereof with a bent structure 55 bent toward the side of the first cooking chamber 15. Similarly, in the bent structure 55, a notch 56 into which the support beam 12b is inserted is formed so that the support beam 12b contacts the top plate 51 in a state where the respective partial plates 50a are supported by the support beams 12b, 12 b. In the present embodiment, the partition 50 is divided into a plurality of divided plates in the conveying direction S of the rice pot P. Specifically, a plurality of sub-plates 50a, 50a … … are provided along the conveying direction S.

Hereinafter, the operation principle of the rice cooking system 1 according to the present embodiment will be described with reference to fig. 4. In the present embodiment, in order to separate the rice pot P in the first cooking chamber 15 from the rice pot P in the second cooking chamber 16, a partition plate 50 (specifically,

partition plates

50a, 50a) is provided in the width direction. The hot air H flowing in through the ventilating portion 41 of the hot air guiding structure 40 cannot directly follow the flow from the first cooking chamber 15 into the second cooking chamber 16 by the blocking action of the partition 50. In this way, the hot gas H flowing into the first cooking chamber 15 through the vent portion 41 temporarily stays in the first cooking chamber 15, and the first cooking chamber 15 can be filled. In the first cooking chamber 15, the hot air H filled therein by staying makes the temperature in the first cooking chamber 15 uniform, so that the whole of the rice pot P transferred into the first cooking chamber 15 can be uniformly heated.

The hot air H further flowing in through the ventilating portion 41 of the heating chamber 14 flows toward the bottom Pb of the rice pot P transferred into the first cooking chamber 15, then flows upward against the periphery of the rice pot P, and further flows into the second cooking chamber 16 through the gap C between the side wall 12a of the cooking chamber 12 and the partition 50. In this manner, in the first cooking chamber 15, since the hot air H flows from the bottom Pb of the rice pot P along the periphery thereof, the rice pot P transferred into the first cooking chamber 15 can be heated more uniformly.

In addition, in the second cooking chamber 16, since the hot air H in the heating chamber 14 directly rises without preferentially heating the rice pot P in the second cooking chamber 16, the whole of the rice pot P conveyed therein can be uniformly heated by the first cooking chamber 15 and the second cooking chamber 16.

However, in the case of the prior art without the partition 50, the hot air H in the heating chamber 14 does not stay in the first cooking chamber 15 and rises directly to the top of the second cooking chamber 16, so that the temperature of the top of the second cooking chamber 16 is higher than the temperature of the bottom of the first cooking chamber 15. At this time, when the measured temperature of the temperature sensor provided at the top of the second cooking chamber 16 reaches the preset temperature, the exhaust fan 60 is started until the temperature of the top of the second cooking chamber 16 is lower than the preset temperature. However, since the temperature of the first cooking chamber 15 is lower than that of the second cooking chamber 16, there occurs a case where the exhaust fan 60 is activated when the first cooking chamber 15 has not reached a proper temperature. In the present embodiment, as described above, by providing the partition 50, the temperature difference between the first and

second cooking chambers

15, 16 can be eliminated, so that the hot air can be effectively utilized, and thus the above-described temperature control of the exhaust fan 60 can be made more reasonable.

In the present embodiment, by providing the concave groove 57 that opens toward the first cooking chamber 15, the hot air can be retained in the concave groove 57, and the entire partition plate 50 can be heated substantially uniformly. The heated partition plate 50 uniformly radiates heat to the entire regions of the first and

second cooking chambers

15 and 16, thereby simultaneously heating the lid Pc of the pot P in the first cooking chamber 15 and the bottom Pb of the pot P in the second cooking chamber 16. In this way, the rice pot P transferred into the cooking chamber 12 can be heated more uniformly.

In particular, since the concave groove 57 opened toward the first cooking chamber 15 is formed in the space surrounded by the adjacent pair of support beams 12b and the bent structure 52 of the partition plate 50, the hot air H stays in the concave groove 57, and the top plate 51 of the partition plate 50 can be heated more uniformly. In this way, the top plate 51 of the partition plate 50, which is heated by the hot air H staying in the groove 57, radiates heat to the entire second cooking chamber 16, so that the second cooking chamber 16 is more uniformly heated, and thus the rice pot P transferred into the second cooking chamber 16 is more uniformly heated.

Further, in the present embodiment, by dividing the partition plate 50 into two divided

plates

50a, 50a in the width direction perpendicular to the conveying direction S of the rice pot P, the hot air H staying in the recess 57 can be allowed to rise through the gap between the divided

plates

50a, 50a adjacent in parallel in the width direction (specifically, the gap C1 between the bent structures 55, 55). Since the rising hot air H flows toward the center of the bottom Pb of the pot P in the second cooking chamber 16, the hot air H can be actively heated from the bottom Pb of the pot P, and the pot P in the second cooking chamber 16 can be heated as a whole.

Further, since the partition 50 is constituted by the plurality of the divided

plates

50a, 50a … … arranged in the conveying direction S and the width direction perpendicular thereto, the partition 50 can be easily detached from the boiling chamber 12 by removing the divided plates 50a one by one, and good maintainability can be achieved.

Further, although the partition plate 50 is divided into a plurality of divided plates in the conveying direction S of the rice cooker P, since the notches 53, 56 (see fig. 3 (b)) into which the support beams 12b are inserted are formed in the portions of the respective

bent structures

52, 55 on both sides in the conveying direction S, even if gaps are formed between the adjacent divided

plates

50a, 50a in the conveying direction S, since the support beams 12b are located in the gaps, the hot air H of the first cooking chamber 15 does not flow into the second cooking chamber 16 through the gaps.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes in design may be made without departing from the spirit of the present invention described in the claims.

Although the partition is formed by providing a plurality of divided plates in the conveying direction and in the direction perpendicular thereto (width direction) in the present embodiment, these divided plates may be constituted by the same plate, for example. For example, the two divided plates in the width direction may be constituted by the same plate.

Further, although the groove in which the hot air of the first cooking chamber stays is provided by placing the partition plate (specifically, the partition plate) provided with the bent structure on the support beam in the present embodiment, the groove may be provided by providing the bent structure over the entire periphery of the partition plate.
