Conventional structure and its problems The structure of conventional high-frequency heating devices such as microwave ovens consists of a metal plate formed into a substantially U-shape, a body plate with a ceiling surface on top, a back plate at the rear, and a front plate. A front plate having an opening approximately equal to the U-shaped cross section of the body plate is attached to the bottom plate by welding or other means. For installation, the front plate and back plate of the heating chamber are extended in one direction, and a space surrounded on three sides by the sides of the heating chamber and the extensions of the front plate and back plate is installed with a high-frequency generator such as a magnetron and It is common to have an electrical room in which electrical components such as a control device are placed, and a metal external member that covers the entire electrical components attached by screws or the like.

In addition, a configuration in which the electric chamber is placed at the bottom or top of the heating chamber is also available, but the basic configuration is the same as the above example, and in either case, the heating chamber and the external material are separate,
It is, so to speak, a double structure, and the external shape is larger than necessary relative to the effective volume of the heating chamber, making it impossible to expect a reduction in occupied space or weight, and in addition, it requires a lot of time to assemble. Ta.

In FIGS. 1 and 2, 1 is a heating chamber, 2 is an electric chamber housing electric control parts such as a high frequency generator, and 4 is a heating chamber 1.
The body plate 5 is the front plate of the heating chamber and has an opening 6 for entering and exiting the heated object, and a door (not shown) that can be opened and closed is attached to cover this opening 6. 7 is a heating chamber back plate. The body plate 4 has a square cross section,
Seven flange portions 8 extending outward are provided on the front and rear sides thereof, and the front plate 5 and the back plate 7 are provided with flanges extending further outward than the seven flange portions 8. After they are placed uniformly over the area and assembled as shown in FIG. 3, they are seamed as shown in FIG. 4. In FIG. 6, the electric room 2 includes a magnetron 1 that generates high frequency waves.
1. Cooling fan 12. Timer 1 for heating time setting
3. Although not shown, high-voltage transformers, capacitors, and other electrical control parts are housed and interconnected. The magnetron 11 connects the antenna 14 to the bottom 4a of the heating chamber.
After insertion, it is connected to the heating chamber bottom 4a with screws or the like, and the electric chamber 2 is also attached with screws or the like in the same manner. These operations are performed through the opening 6 in the front plate. 15 is a high-frequency stirring device that directs the wind from the cooling fan 12 to the guide plate 16.
It is guided into the heating chamber by the wind, and is rotated by this wind. After stirring, the claws pass through the pores 18a at the bottom of the back plate 7 and exit the exhaust guide 1.
7 to the upper pore 18b and enter the heating chamber again. Reference numeral 19 denotes a floor plate made of a material with a low dielectric constant such as glass, ceramic, or resin, which hides the magnetron antenna 14, the stirring device 16, and the screws that attach them, and also serves as a platform for placing objects to be heated. Become. Note that the surface of the floor plate 19 is aligned with the lower edge of the opening 6 of the front plate 6,
This makes it easier to take in and out the heated items, and also makes it easier to remove water and debris when cleaning the heating chamber.

なお、扉は第5図において破線にて示す。Note that the door is indicated by a broken line in FIG.

加熱室1を第2図のように構成すれば、加熱室の外壁面

If the seaming process is performed as shown in FIG. 4, there is no risk of high frequency leakage, but spot welding may be used as a joining means if spot welding can be reliably performed at fine pitch intervals over the entire circumference. In this case, the box-shaped heating chamber 1 is formed and then painted.

However, the painted surface of the weld marks remains uneven, making it extremely difficult to achieve the best appearance. On the other hand, in the case of seaming, post-painting is also possible, but by using a metal plate that has been coated on both sides in advance, the seamed and joined state becomes a completed product as a heating chamber without post-painting. In this case, there is an advantage in that, by using different paint colors on the front and back sides, it is possible to select various colors for the outer surface even though the inner surface of the heating chamber is the same color.

Therefore, as shown in FIG. 6, the body plate 4 and bottom plate 4a of the heating chamber are
If these are made into separate parts, the bottom plate 4a is a normal unpainted metal plate, and the other parts are coated metal plates, and they are joined by seam folding and caulking as shown in the cross section in Fig. 7, the cross section will be square as shown in Fig. 2. body plate, and there is no high frequency leakage from the joints. Since this unpainted part is not suitable as an outer shell material, the dimensions are set so that it will be covered by the electrical room when the electrical room 2 is connected. Note that the seam-fold crimping shown in FIG. 7 is also effective as a method for joining the ends when forming a body plate with a rectangular cross section from a single metal plate.

FIG. 8 shows another persimmon example, in which the electric chamber 2a is connected to the side of the heating chamber 1a. At this time, the floor plate 19 provided at the bottom of the heating chamber serves as a mere platform for placing the object to be heated. The magnetron 14 is attached to the side wall of the heating chamber, and if a high frequency stirring device 15 is required, the magnetron 14 is attached to the heating chamber 1 together with the cover 20.
Installed on the ceiling surface of a. Alternatively, it may be provided at the bottom of the floorboard 19.
