Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microwave cooking device using a microwave oven.
The present invention relates to a microwave heating type cooking apparatus suitable for a rice cooking factory that supplies rice and lunches to a catering company, a convenience store chain, and the like.

[0002]

2. Description of the Related Art In general, a heating container used in a home microwave oven is made of various materials such as metal, plastic, ceramics, and glass. Also,
The shape of the container body is also mainly a round shape, has an oval shape or a square shape, and when cooking an object to be heated, the heating container is placed directly on the bottom surface of the microwave oven, or a turntable is attached. Used by setting through.

[0003] Various measures have been devised for such a heating container in order to easily bring it into and out of a microwave oven during cooking of an object to be heated, and to easily carry it with bare hands immediately after heating. . For example, Japanese Utility Model Laid-Open No. 64-9144
As disclosed in Japanese Patent Application Publication, a flange-shaped handle is provided on a part of the peripheral edge of the upper end opening of the container body, and a rib is provided on a flange forming the handle to reinforce the handle.

[0004]

However, in a home microwave oven, it is almost impossible to cook rice directly because it is used only for heating and cooking frozen foods such as rice that has been cooked and frozen. Not done.

[0005] On the other hand, most factories specializing in cooking rice, which supply rice and lunches to catering companies and convenience store chains, use large gas cookers, but rice cookers using such large gas cookers. Automation and unmanned systems are difficult. As mentioned above, when using a large gas cooker at a rice cooker factory to cook large amounts of rice,
Since the heat source is a gas, that is, a gas, the volume of the gas itself easily expands or contracts due to a change in the temperature of the atmosphere in the factory, and the thermal power constantly fluctuates. In addition, when rice is cooked, the temperature of the atmosphere in the factory rises sharply. To cook delicious rice, you need to finely adjust the heat and so on. Cost.

[0006] In such a large gas cooker, a heat source is arranged below the pot and the rice is cooked by using the convection action. Heating is not possible. In addition, since the kettle itself is large, partial unevenness in temperature is generated anyway, and uneven cooking is apt to occur, thereby causing unevenness in cooked quality. Therefore, it is difficult to set up an automated and unmanned line by using a conventional large gas cooker.

An object of the present invention is to provide a microwave heating type cooking apparatus in which a large number of objects to be heated are uniformly heated, and a large heating container can be easily conveyed into and out of a microwave oven. .

[0008]

In order to solve the above-mentioned problems, the present invention provides a heating container for accommodating an object to be heated, and heating the object by placing the heating container in a refrigerator. In a cooking apparatus including a microwave oven main body, the heating container has a cylindrical or substantially cylindrical round bottomed cylindrical body, and a planar square flange provided near the upper end opening periphery of the bottomed cylindrical body. The microwave oven body is characterized in that a guide member for supporting a flange portion of the heating container is provided on both left and right wall surfaces in the refrigerator.

[0009] Further, the guide member may be constituted by a plurality of rolling elements arranged along a depth direction inside the refrigerator of the microwave oven main body.

[0010] The bottomed cylinder of the heating vessel may be formed of a plastic material having a low dielectric constant, heat resistance and steam resistance. In this case, it is desirable that the flange portion of the heating container is formed integrally with the bottomed cylindrical body using the plastic material.

[0011]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a configuration diagram schematically showing the overall configuration of a rice cooking system using a commercial automatic rice cooker according to the present invention. As shown in FIG. 1, the automatic container transport line in this rice cooking system is formed by a monorail R installed in a ring shape (loop shape) on the ceiling of a rice cooking facility such as a rice cooking factory. The automatic guided vehicle 1 that is driven and controlled by a command from a central control center (not shown) can run on its own. A plurality of suspension belts 2 wound and wound by a winding / winding machine (not shown) hang down from the automatic transport vehicle 1.
The automatic container loading / unloading machine 3 is suspended and supported, and the automatic container loading / unloading machine 3 is also driven and controlled to move up and down in response to a command from a central control center.

The automatic container loading / unloading machine 3 includes a container supporting arm 4
The container support arm 4 can be driven to expand and contract by a drive mechanism (not shown) according to a command from a central control center. Further, a heating vessel 10 for cooking rice in which immersed rice is accommodated together with hot water or the like is mounted on the container support arm 4 through steps such as unpolished rice washing, washing and soaking of rice (not shown). .

That is, the supporting arm 4 allows the heating container 10 to be carried into the oven 21 of the microwave oven 20 to be described later by its extension operation. This makes it possible to take out the heating container 10 later.

As shown in FIG. 2, the heating vessel 10 is a cylindrical or substantially cylindrical round bottomed cylinder 11 made of a plastic material having a low dielectric constant, heat resistance and steam resistance, such as polypropylene. And a rising wall portion 12 formed stepwise on an upper peripheral edge 11a of the bottomed cylindrical body 11.
And a cover plate 13 detachably fitted to the stepped rising wall portion 12. A flange 14 having a flat rectangular shape similar to the flat shape in the oven chamber 21 of the microwave oven body 20 to be described later is integrally formed around the upper end opening periphery 11a of the bottomed cylindrical body 11. Each corner portion 14a of the flange portion 14 is rounded so that the inside of the oven storage 21 can be smoothly taken in and out.

On the other hand, as shown in FIG. 3, a large-sized microwave oven body 20 for business use is installed at an installation place G corresponding to the automatic container transport line. The microwave oven main body 20 has an oven box 21 having a rectangular box-like space in which rice can be cooked uniformly by electric control such as heating by a microcomputer. In the oven storage 21, microwaves are emitted from a magnetron (not shown), which controls and adjusts the degree of fire during rice cooking, according to a command from the central control center, and a door 22 is provided on the front surface thereof. ing. The door 22 is provided, for example, at the front of the oven
By detecting a state when rice is carried and the rice is cooked in the oven storage 21 by a sensor (not shown) or the like, the door is automatically opened by a drive motor (not shown). It has become.

The oven 2 of the microwave oven body 20
A guide member 23 for supporting the flange portion 14 of the heating vessel 10 is provided on both left and right wall surfaces 21a in 1. The guide member 23 has a configuration in which a plurality of rolling rollers 24 are arranged along the depth direction in the oven cabinet 21. Each of the rolling rollers 24 is made of metal as shown in FIG. It is rotatably attached to both left and right wall surfaces 21a in the oven storage 21 with screws 25.

In this case, each of the rolling rollers 24 can be arranged with an angle θ so as to be inclined downward in the depth direction in the oven storage 21.

Since the inside of the oven 21 of the microwave oven body 20 is formed as a rectangular box-like space, the microwave radiated from the magnetron is weak near the corners of the oven 21 and strong at the center thereof. Therefore, the strength tends to be relatively uniform. Therefore, in the present invention, by making the shape of the heating vessel 10 a basic form consisting of a cylindrical or substantially cylindrical round bottomed cylinder 11,
This enables uniform heating of the heating container 10 in the oven storage 21.

Also, as described above, the microwave oven main body 2
0 makes it easy to control rice cooking such as heating and cooling by a microcomputer, so that it is possible to prevent the occurrence of uneven temperature and uneven cooking due to the convection of a heat source as in a conventional gas cooker. Thus, the quality of the cooked rice is improved.

That is, in the rice cooking system using the commercial automatic rice cooker according to the present invention having the above-described configuration, the heating container 10 in which immersed rice is accommodated together with hot water or the like and covered is covered.
Is mounted on a container support arm 4 which can be extended and contracted on an automatic container loading / unloading machine 3 suspended from an automatic carrier 1. Next, the automatic container loading / unloading machine 3 is raised, and the automatic transport vehicle 1 is caused to self-propelled toward the installation location of the microwave oven main body 20 so that the heating container 10 is moved to a position corresponding to the installation location G of the microwave oven main body 20. Transport to

When the heating container 10 reaches a position corresponding to the microwave oven main body 20, the automatic container loading / unloading machine 3 is lowered and the heating container 10 is moved to the oven chamber 2 of the microwave oven main body 20.

At this time, the automatic container loading / unloading machine 3 operates the flange portion 1 of the heating container 10 mounted on the container support arm 4.
4 stands by so that it is located slightly above the position of the guide member 23 provided in the oven chamber 21 of the microwave oven body 20, and the flange portion 1 of the heating vessel 10 to the guide member 23
4 can be placed.

In this state, the heating container 10 on the automatic container loading / unloading machine 3 is detected by a sensor (not shown), and the door 22 of the microwave oven body 20 is automatically opened. This door 2
When the door 2 is opened, the container support arm 4 of the automatic container unloader 3 is extended, and the heating container 10 is carried into the oven chamber 21 of the microwave oven body 20.

When the heating container 10 is carried into the oven 21 of the microwave oven body 20, the flange portion 14 of the heating container 10 is placed on the guide members 23 provided on the left and right wall surfaces 21a in the oven 21. Then, the heating container 10 moves along with the elongating operation of the container supporting arm 4 along the guide member 23 and is carried in. At this time, since the guide member 23 is constituted by the rolling roller 24, the movement of the heating container 10 is facilitated by the rolling of the rolling roller 24.

In this case, when the rolling rollers 24 constituting the guide member 23 are arranged so as to be inclined downward in the depth direction in the oven chamber 21, the heating chamber 10 causes the oven chamber 21 to move by its own weight. The force that naturally falls toward the inside in the depth direction acts, and the movement of the heating container 10 into the oven storage 21 becomes smoother.

When the heating container 10 is taken into the oven 21 in this way, the automatic container loading / unloading machine 3 is once lowered, and the heating container 10 is opened from above the container support arm 4 to be guided by the guide member 23. It is completely positioned and mounted on the upper predetermined position. In this state, the container support arm 4 returns to the original position after the contraction operation, and the door 22 closes upon detection of a sensor (not shown). At this time, when the container support arm 4 returns to the original position, the automatic container loading / unloading machine 3 moves upward by the drive of the automatic transport vehicle 1 and shifts to the next container transport stage. The other heating container 10 is conveyed and carried into the microwave oven body 20.

On the other hand, when the closed state of the door 22 is confirmed, the microwave oven main body 20 is operated, and while the rice cooker is controlled by the microcomputer based on a preset rice cooker program, the microwave is radiated from the magnetron. The heating vessel 10 is heated by the microwaves to be cooked, and the immersed rice housed in the heating vessel 10 is cooked.

When the rice immersion of the immersed rice in the heating container 10 is completed, the automatic transport vehicle 1 drives the automatic container loading and unloading machine 3.
Is moved again, and the oven 2 of the microwave oven body 20 is moved again.
1 Lower to the front. At this time, the automatic container loading and unloading machine 3
The container support arm 4 stops at a position corresponding to the position below the heating container 10 placed on the guide member 23 in the oven storage 21 and waits, and at the same time, the door 22 opens.

When the door 22 is opened, the container support arm 4 of the automatic container loading / unloading machine 3 is extended toward the inside of the oven 21 of the microwave oven body 20, and the container support arm 4 is inserted below the heating container 10. And stop. In this state, the automatic container loading / unloading machine 3 is raised, and the heating container 10 is captured by the container supporting arm 4, and then the container supporting arm 4 is contracted to the original position, and the heating container 10 is taken out. The cooked rice container 10 after cooking rice is mounted on the in-out machine 3 again. At the same time, the door 22 closes.

The cooked rice cooker 10 mounted on the automatic container loading and unloading machine 3 is provided with a rice cooker (not shown) for loosening cooked rice.
It is conveyed toward a cooling step, a step of removing cooked rice, a step of cleaning the heating vessel, and the like, whereby the rice cooking step is completed.

In the above-described embodiment, the flange portion 14 of the heating vessel 10 is formed integrally with the bottomed cylinder 11, but the invention is not limited to this. A portion 14 may be provided. In this case, as the material of the flange portion 14, a plastic material different from the bottomed cylinder 11 can be used. Further, in addition to the rice cooking, the automatic rice cooking device having the above configuration can be applied as, for example, a cooking device for “side dishes”, and it is needless to say that various modifications can be made without departing from the gist of the present invention. Nor.
