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 for performing heat treatment on various foodstuffs, and in particular, an oven for separately providing objects to be heated in the heating device. Among them, the present invention relates to a batch-type composite heating device in which microwave heating and hot air heating are used in combination.

[0002]

2. Description of the Related Art Although a conventional heating device using only microwaves, such as a microwave oven, is suitable for heating foodstuffs from the inside, the surface of the foodstuffs could not be raised well. 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 heating device, since the object to be heated is cooked inside the heating device main body, a great deal of labor has been spent on cleaning dirt due to cooking.

[0004]

The present invention complements the drawbacks of these conventional heating devices, that is, the microwave heating device or the convection function or the hot air jetting function when used alone, and It eliminates the great effort expended on cleaning the heating device.

Show.

As shown in FIG. 2 and FIG. 3 showing the state of the cabinet 1 after the oven chamber 5 is taken out from the cabinet 1, as shown in FIG.
From here, the oven 9 as well as the object to be heated 9 can be freely put in and taken out. By adopting such a configuration, it becomes possible to easily wash the oven chamber 5. FIG. 4 shows other parts taken out from the cabinet 1.

As shown in FIG. 2, the heat treatment of the object 9 to be heated in the oven chamber 5 by the apparatus of the present invention is carried out through the oven chamber 5 by two heating means, a microwave means and a hot air means. The microwave means irradiates the object to be heated 9 in the oven chamber 5 with microwaves, and the hot air means blows hot air to the object to be heated 9 in the oven chamber 5. The microwave means includes a magnetron 13 and a waveguide 22 having a microwave irradiation port 14. The microwave oscillated by the magnetron 13 is applied to the object 9 to be heated in the oven chamber 5 from the microwave irradiation port 14 through the waveguide 22. The hot-air unit includes a heating device 17, an internal circulation fan motor 16, an internal circulation fan 15, and a ventilation louver 21 that ventilates the inside of the cabinet 1.
The air in the cabinet is heated by the heating device 17, circulated by the internal circulation fan 15 rotated by the internal circulation fan motor 16, and reaches the oven chamber 5 through the straightening plate 24. After that, this hot air is stored in the oven
Heat is jetted through the orifices 18 provided at the upper and lower parts of the heat treatment unit and collides with the object to be heated 9. These two means are used together for the heat treatment. Therefore, the drawbacks of the prior art when using the microwave means or the hot air means alone are overcome.

The heat treatment by these heating means provided inside the cabinet 1 is directly performed by the cabinet 1.
It is performed in the oven chamber 5 housed inside. Therefore, even if the heat treatment is performed, the cabinet 1 constituting the main body of the heating device is not directly contaminated, and therefore it is not necessary to wash it. On the other hand, the inside of the oven chamber 5 will be soiled due to heat treatment or the like and will need to be cleaned, but by opening the front door 1, it can be easily taken out from the access port 7 provided in the cabinet 1.

It is composed of a frame 32. No front plate is provided. This is because it is unnecessary because the object to be heated is taken in and out from the front of the oven chamber. To disassemble the oven chamber 5, (1) take out the small chamber inner frame 32 inserted inside the oven chamber 5, and (2) plate 2
This is performed by a very simple process of taking 3, 25, 27, 29 from the inside of the internal frame 31. Obviously, it is easy to assemble. In this way, the oven chamber 5 can be easily disassembled, and thus the oven chamber 5 can be washed more easily.

The plates 23, 2 forming the oven chamber
5, 27 and 29 have been subjected to some treatments in order to perform heating or to attach an oven to the cabinet. First, in order to facilitate heating, particularly microwave heating, all the plates are made of a microwave-transparent material having heat resistance. However, not all the plates are necessarily made of such a material, and the object of the present invention can be sufficiently achieved even if only the top plate is made of this material and other plates are made of other metal materials. Second
In order to perform hot air jet heating, an orifice 18 for generating hot air jet is provided on the plate forming the top and bottom of the oven chamber, and an orifice for discharging hot air is provided on the plate forming the back face of the oven chamber. Having established 19. Thirdly, the turntable cabinet 1
The bottom plate 2 has holes 20 that enable easy attachment and detachment from the
It was installed in 9.

The attachment and detachment of the oven cabinet 5 to and from the cabinet 1 can be easily performed as in the disassembly and assembly of the oven cabinet 5 . As apparent from FIGS. 2 and 5, for example,
To remove this oven cabinet 5 from the cabinet 1,
This can be achieved by simple operations such as (1) removing the turntable 10, (2) removing the rotary shaft 11 that serves to rotate the turntable 10, and (3) pulling out the oven chamber 5. Installation is accomplished by the reverse operation. At the time of installation, the rotating shaft 11 is a bottom plate play.
