Description

[Detailed description of the invention] This invention relates to an improvement of a rice cooker that is a more compact three-dimensional circulation rice cooker.

Conventionally, while a large number of rice cooking pots are circulated and moved by a three-dimensional circulation chain conveyor, the rice is boiled in the lower running part of the rice cooker using the direct fire of the burner, and then the rice is transferred to the upper running part of the conveyor and steamed using the exhaust heat of the burner. Various small three-dimensional circulation type rice cookers are known.

By the way, this type of three-dimensional circulation rice cooker is smaller and has a smaller path than a continuous automatic rice cooker using a straight conveyor, but there is also less demand for a more compact rice cooker. do not have.

Therefore, when manufacturing a smaller rice cooker, it is naturally necessary to shorten the travel length of the rice cooker, but the conditions for cooking rice, such as boiling time, temperature, and steaming time and temperature, are different for small and large rice cookers. Since the same conditions are required regardless of the rice cooker, it is not possible to achieve the function as a rice cooker simply by shortening the path length.

Therefore, it is conceivable to reduce the speed at which the rice cooker travels along the path by the amount that the path length is shortened, but in this case, the rice cooker will move onto the burner at the start and end of heating, and the speed at which it will be removed will be slow. As a result, there is a problem that the heating unevenness of the rice cooker as a whole becomes significant, making it difficult to cook rice well, and there is also a problem that sufficient steaming cannot be achieved because the exhaust heat from the burner is small and easily escapes to the outside.

In order to solve the above-mentioned problems, this invention proposes a more compact three-dimensional circulation type that can achieve good rice cooking without causing uneven heating in the rice cooker at the start and end of heating with a burner.

An example of this invention shown in the drawings will be explained below.
Inside the fuselage 1, a pair of chain conveyors 7 are installed symmetrically, which circulate around the front and rear sprockets 2 and 3 and the sprocket 4°5.6 installed above them. Below between the runs is a series of burners 8.
The machine body 1 on the front side of the conveyor 7 is provided with a loading port 9 for the rice cooker A at the bottom and a loading port 10 at the top.
12 are installed.

A large number of support arms 13 facing vertically outward are fixed to the left and right chain conveyor 7 at right angles to the conveyor and at intervals approximately equal to the front and rear width of the rice cooker A.
A support holder 14 is attached to the tip of the rice cooker A for supporting both sides of the rice cooker A and transporting the rice cooker A.

For example, as shown in the figure, the support receiver 14 has a stopper provided on the horizontal surface that supports the rice cooker A, and a roller 15 is attached to the lower part of the stopper, and the center portion is pivoted to the support arm 13 so that the horizontal surface remains horizontal. Configure.

A guide rail 16 on which rollers 15 are placed and allows the support holder 14 to travel is provided at a moving portion of the support holder 14 that moves along the lower running portion of the chain conveyor 7 together with the support arm 13.

In addition, between the lower running parts of the left and right chain conveyors 7, there is provided exhaust heat (hot air) rising from the lower burner 8 that shields the moving path of the rice cooker A moving along the lower running part. )
Exhaust guide plate 1 that guides the air to the rear of the chain conveyor 7
7 is installed.

When the drive switch is turned on, the chain conveyor 7 rotates for a short period of time (for example, around 1 minute) for a length equal to the front and back width of the rice cooker, then stops for a predetermined period of time (for example, around 3 minutes), and repeats this operation intermittently. Do some exercise.

When the chain conveyor 7 is stopped, a plurality of (four in the figure) support arms 13 are positioned downward on the lower running part of the chain conveyor 7.
The rice cooking pots A are configured to be supported by the respective support holders 14 in close proximity to each other.

Furthermore, among the plurality of rice cooking pots A supported on the lower running part of the chain conveyor 7 in this way, the rear rice cooking pot A installed on the carry-in port 9 side is placed on the carry-in conveyor 11 and is not heated by the burner 8. The rice cooker A in front of the rice cooker A is located on the burner 8 and is heated by this.

A hot air regulating plate 18 is installed in front of the tip of the burner 8.

When the chain conveyor 7 is stopped, the hot air regulating plate 18 shields the front surface of the first rice cooking pot A supported on the lower running portion of the chain conveyor 7 while keeping a small distance from the front surface, and protects the tip of the burner 8 from the front surface. The structure is configured to guide the hot air rising from the rice cooker A along the front surface of the rice cooker A, and when the rice cooker A moves upward along the sprocket 3, a position is established where this movement cannot be blocked. It is designed to be displaced to .

As such a hot air regulating plate 18, for example, a plate with a groove-shaped cross section is pivoted at its lower end in front of the tip of the burner 8 with the groove facing the front of the rice cooker A, and the front side of the rice cooker A is fixed by a spring 19. The rice cooker A is given elasticity so that it is tilted, and after the rice cooker A is turned, it returns to the front from the rearward tilted position.

The gap formed between the hot air adjusting plate 18 and the front surface of the first rice cooking pot A is such that the front surface is heated to the same temperature as the rear surface of the first rice cooking pot A is heated by the hot air of the burner 8. Set it so that

(For example, the gap is set to be equal to the gap between the front and rear rice cooking pots.) When cooking rice in the above configuration, the rice cooking pots A are sequentially supported on each support holder 14 as shown in the figure, and the chain conveyor 7
rotate intermittently.

The figure shows a state in which the chain conveyor 7 is temporarily stopped.
The three rice-cooking pots A in the lower running section are located close to each other on the burner 8, and the bottom surface and both front and rear sides are heated by the flame and its hot air, and the front surface of the first rice-cooking pot A is It is heated by the hot air adjustment plate 18 under the same conditions as the rear surface.

On the other hand, the exhaust heat from the burner 8 is guided to the rear of the chain conveyor 7 by the exhaust guide plate 17, flows to the upper side of the machine body, further flows along the top plate of the machine body 1, and flows to the exit port 1.
0 out of the aircraft.

Therefore, the rice cooking pot A supported on the upper running part of the chain conveyor 7 is heated by the hot air flow flowing along the upper running part, and the boiled rice inside is steamed.

Next, after a predetermined period of time has elapsed, the chain conveyor 7 rotates by the front and back width of the rice cooker A, and the first rice cooker A in the lower running portion is turned upward and is carried in through the carry-in port 9 and placed in the support holder 14. The new rice-cooking pot A supported by the chain conveyor A is moved onto the burner 8, and the rice-cooking pot A that has completed the steaming process at the top of the upper running section of the chain conveyor A is automatically placed on the carry-out conveyor 12 and carried out. Ru.

In this case, since the rice cooker newly moved onto the burner 8 can move at a speed equal to or faster than that of the conventional rice cooker, uneven heating will not occur.

In addition, the rice cooker A, which is turned upward from the lower running part of the chain conveyor 7, moves at a high speed as well, and since the hot air adjustment plate 18 is in contact with the front surface of the pot with a gap, it moves upward a little. During this time, the hot air from the burner 8 is received in the same way as the rear surface, and uneven heating does not occur.

The rice cooker A carried in from the carry-in port 9 in this way moves and stops repeatedly until it is carried out from the carry-in port 10, and stays in the machine body 1 for a sufficient time, and is sufficiently boiled by the burner 8. The rice is sufficiently steamed by the exhaust heat of the burner flowing slowly inside the body 1, and the rice is cooked well.

As described above, according to this invention, the chain conveyor rotates,
Since the rice cooker rotates intermittently with repeated stops, the rice cooker can remain inside the machine for a sufficient period of time without slowing down the rotation speed, and sufficient boiling and steaming time can be secured using the burner and its exhaust heat. At the same time, the time taken to start and end heating by the burner of rice cooker A can be made faster.
No uneven heating occurs during the movement.

In addition, a predetermined gap is maintained between the front of the tip of the burner and the front of the first rice cooking pot supported on the lower running part of the chain conveyor to shield the front of this rice cooking pot, and the rice cooking pot is moved. Since the hot air adjustment plate is installed at a position where its movement is not blocked, the hot air at the tip of the burner is reliably guided to the front of the rice cooker without being dissipated, and heated under the same temperature conditions as the rear side. This enables uniform heating without uneven heating.

Therefore, it is possible to construct a compact three-dimensional circulation rice cooker that is more compact than the conventional three-dimensional circulation rice cooker in which the moving path of the rice cooker is shortened, and it is also possible to cook rice as well as the conventional three-dimensional circulation rice cooker.
