Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a batch type heating device and a package for heat-treating foodstuffs. In particular, the heat treatment is carried out by combining microwave heating and hot air jet heating. The present invention relates to a device and a package which can be performed at high speed and with high quality, and can be used as a cooking container.

[0002]

2. Description of the Related Art A conventional heating device using only microwaves, such as a microwave oven, is suitable for heating foods, but the surface of foods cannot be raised. On the other hand, the conventional heating device using only the convection function or the hot air blowing function is suitable for raising the surface, but it took a long time to cook. As described above, in the conventional heating device, for example, a relatively thick object to be heated cannot be baked with high quality and at high speed from the surface to the inside.

Further, in the conventional batch type heating device,
Due to the low heat resistance of the packaging container, the food could only be heated after the food was transferred to another suitable cooking container. For this reason, it takes extra time when heating, and in addition, since the heated food material is generally transferred to another packaging container again, there is a drawback that the heated food material is cooled and loses its taste.

[0004]

The present invention complements the drawbacks of these conventional heating devices, that is, the microwave heating device and the convection function or the hot blast function, respectively. In addition, the package, which is a packaging container, can be used also as a cooking container so as to save the labor required for the heat treatment. Further, in the present invention, an improvement is made so that the heat treatment can be performed more effectively and easily by using these devices and packages.

[0005]

A cabinet constituting a main body of a heating device according to the present invention has a package mounting table for mounting a package containing an object to be heated, and the package mounting table arranged inside. Such a heating space and a loading / unloading opening for loading / unloading the package into / from the heating space. The package mounted on the package mounting table is directly or indirectly housed in the heating space through the loading / unloading port. The storage of the package in the heating space is performed by vertically moving the package mounting table on which the package is mounted by the elevating means or by moving the package mounting table in the horizontal direction by the sliding means. In some cases, the inside of the loading / unloading port of the package immediately becomes a heating space, and in this case, the movement of the package mounting table is not required.

After the package is stored in the heating space,
Heat treatment is performed. In the apparatus according to the present invention, the heat treatment for the object to be heated in the package is performed by using hot air, particularly hot air jetting, and microwaves together. By using these in combination, high speed and high quality heat treatment becomes possible. In order to perform hot air jet heating, hot air is required first. The hot air is generated by hot air means provided inside the cabinet. The hot air generated by the hot air means is directed toward the package mounted on the package mounting table by the hood means provided in the heating space of the cabinet. The hot air from the hood means arranged in the vicinity of the package passes through the orifice provided in the package to be a hot air jet, and is introduced into the package. This hot air jet forms a heating chamber inside the package, and as a result, hot air jet heating is performed.
Two methods are used in the present invention in order to bring the hood means and the package close to each other. One is a method in which the hood means itself is moved and the package mounting table on which the package is mounted is fixed, and the other is a method in which the hood means is fixed and the package mounting table on which the package is mounted is hooded. It is a method of getting closer to the means. Which one is used depends on the difference in the method of storing the package in the heating space described above. On the other hand, the microwave required for microwave heating is generated by the microwave means in the cabinet, and is then irradiated to the object to be heated in the package from the microwave irradiation port for irradiating the microwave provided in the heating space. It

In the package according to the present invention, the object to be heated inside the package can be heated with hot air and microwaves, in other words, the package itself containing the object to be heated can be used as a cooking container. Configured as First, the package was provided with multiple orifices to allow hot air jet heating. These orifices are classified into hot air jetting orifices and hot air jetting orifices. The hot air blowing orifice serves to form hot air from the hood means arranged in the vicinity of the package into hot air and form a heating chamber inside the package. The hot air discharge orifice serves to discharge the used hot air sprayed onto the object to be heated. Secondly, since heating is performed by microwave irradiation, the package is formed of a microwave transparent material having a small heat capacity. By configuring the package in this way and making it with such materials,
In the present invention, the package could be used as a cooking container.

Further, in the present invention, in order to perform the heat treatment more effectively, or in order to make the heat treatment easier,
Made improvements. First, in order to more effectively perform the heat treatment, particularly the heat treatment by hot air jetting, the device was configured so that the hood means covers the upper half of the package. By configuring the device in this manner, lateral leakage of hot air from the hood means is prevented during hot air jet heating, and the heating chamber is better formed inside the package 31. Correspondingly, the package has been improved. The package is composed of an upper lid and a main body, and an orifice for hot air injection is attached to the upper lid
An orifice for discharging hot air was provided below the periphery of the side surface of the main body. By providing the orifice at such a position,
The hot air jet is guided to the inside of the package without exception, and all of the hot air jets effectively serve for heating. Also, the upper lid is 2
With the double structure, the hot air can be rectified so that the heat treatment can be performed more effectively.

Although optional, in order to facilitate the heat treatment by operating the apparatus of the present invention, a bar code containing information necessary for heating is printed on the side surface of the package, and a reading means for reading the bar code. It is also possible to provide the device of the invention.

Food means and package 31
Two methods have been used in the present invention to bring the and close together.
One is a method of moving the hood means without moving the package mounting table on which the package 31 is placed, and the other is a method of bringing the hood means itself into the package 31.
It is a method of approaching to. It is possible to move both the hood means and the package mounting table, but this time, these two methods were used. Which of these two methods is used depends on the difference in the method of storing the package 31 in the heating space 11 described above. The embodiment shown in FIG. 1 corresponds to the package mounting table on which the package 31 is mounted, that is, the one for moving the elevating bottom plate 4 in FIG. This can be easily achieved with the device shown in FIG. Store the package 31 in the heating space 11,
This is because the vertical bottom plate 4 is moved in the vertical direction, and this can be easily achieved by pulling up the vertical bottom plate 4 to a position where the package 31 approaches the hood means. The embodiment shown in FIGS. 4 to 8 and 9 to 10 is to move the hood means itself. In FIGS. 4 to 8 and 9 to 10, the lifting and lowering of the hood means is performed by a hood lifting and lowering motor 27 provided in the upper part of the cabinet 1. The hood means and the package 31 are brought close to each other by these methods, and the hot air introduced from the hood means is jetted by the orifice provided in the package 31. A heating chamber is formed inside the package 31 by this hot air jet, and hot air jet heating is possible. The hot air sprayed onto the object to be heated 24 inside the package 31 is then guided from the hot air outlet 43 provided in the lower part of the heating space 11 to the ventilation pipe 38 by the exhaust chamber 39, and the ventilation louver provided in the ventilation pipe 38. It is discharged from the outside through the ventilation gallery 40. In addition,
In the lower part of the hot air fan motor 7 and the ventilation pipe 38,
Since it is suspended vertically by the hot air fan motor holding spring 37, a hot air fan motor stopper 45 and a ventilation pipe stopper 44 are provided to prevent excessive dropping. On the other hand, the microwave heating is performed by radiating the microwave generated by the magnetron 9 from the microwave irradiation port 10 below the heating space through the waveguide 12 provided in the middle part of the cabinet 1. In this specification, what is necessary for microwave heating, such as the magnetron 9 and the waveguide 12, is called a microwave means. However, this does not include the microwave irradiation port 10.

The package 31 according to the present invention is formed corresponding to the device of the present invention as described above. The package 31 according to the present invention is the object to be heated 2 inside the package 31.
In order to enable the hot air jet heating and the microwave heating to the No. 4, in other words, the package itself containing the object to be heated is formed so as to be usable as a cooking container. First, a large number of orifices are provided in the package 31 to enable hot air jet heating. As shown in FIGS. 11 and 12, these orifices are divided into a hot air jetting orifice 25 and a hot air exhausting orifice 26.
