Description

[Detailed explanation of the idea] The present invention relates to a cooking appliance equipped with a high frequency oscillation source.

Conventionally, in order to prevent radio wave leakage from around the front door of this type of cooker, a decorative frame is provided on the front side of the cooker body with the inner surface facing the circumferential side of the door. It is known that a radio wave absorber such as ferrite rubber is attached to the side surface to absorb leaked radio waves, but in this case, the absorber is generally attached to the decorative frame with screws, etc. It is known that assembly is difficult, and the decorative frame is made of extruded aluminum or the like and has grooves for inserting the absorber in order to improve assembly. However, this method involves the disadvantage of being expensive due to the use of molded materials.

The purpose of the present invention is to provide a cooker that eliminates such inconveniences, and has an inner surface facing the circumferential side of the front door 3 on the front side of the cooker main body 2 equipped with the high frequency oscillation source 1. In the case where a decorative frame 4 is provided and a radio wave absorber 5 is attached to the inner side of the decorative frame 4, the decorative frame 4 is made of a sheet metal outer plate having a bent edge 6 forming the front edge of the inner side. It is composed of a frame 7 and an inner frame 9 made of sheet metal having a recess 8 recessed outward to receive the absorbent body 5, and the inner frame 9 is attached to the outer frame 7 at the front edge of the recess 8. The folded edge 6 is connected to the inner side, and a cut and raised piece 10 is formed on the inner frame 9 to face the inner side of the rear edge of the recessed part 8.
The cut and raised pieces 1o form a groove 11 into which the absorbent body 5 can be inserted and removed from the outside in the longitudinal direction of the decorative frame 4.

The drawing shows an embodiment in which the front door 3 is of an upward-opening type, and a radio wave absorber 5 is provided on the inner surface, that is, the lower surface, of the decorative frame 4 at the top of the door 3, which is particularly susceptible to radio wave leakage. The decorative frame 4 includes the above-mentioned outer frame 7 and inner frame 9.
The front edge of the inner frame 9 is superimposed and bonded onto the lower bent edge 6 by spot welding or other means, and then the radio wave absorber 5 is attached to the groove 11 with stepped edges on both front and rear sides thereof. 5a
v5a is inserted from left and right so that it is sandwiched between the recess 8 and the bent edge 6, and between the recess 8 and the cut and raised piece 10, respectively, and this assembled body is inserted between the outer frame 7 and the inner frame 9. Mounting base 1 on each rear with
In 2.13, screws were fixed to the top and front surfaces of the cooking device main body 2.

In the drawing, 14 is a top plate attached to the top surface of the cooking device main body 2, and 15
indicates a heating chamber housed within the main body 2.

In the illustrated embodiment, the decorative frame 4 into which the radio wave absorber 5 is inserted is provided only at the top of the front door 3, but it may of course be provided over the entire circumference of the door 3.

As described above, according to the present invention, the decorative frame 4 is constituted by the outer frame 9 and the inner frame 9 made of sheet metal, which can be obtained at a lower cost than when using a shape material such as an extruded shape material, and the inner frame 4 is made of sheet metal. A groove 11 into which a radio wave absorber 5 can be freely inserted is formed by a recess 8 formed in the frame 9, a cut and raised piece 10, and a bent edge 6 formed in the outer frame 7. This has the effect of improving the ease of assembly.
