Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a cooking device for baking using a gas burner as a heat source.

(Prior Art) The applicant of the present application has previously developed a cooking device of this type in which one side is installed on the left and right sides in a baking chamber equipped with a gas burner or other heat source.
In addition to providing a pair of guide rails, a frame casing is supported on the rails by a pair of right and left flanges so as to be freely drawn out forward, and the frame casing is provided with a convex portion formed on each side of the frame casing. In the type that can be engaged with a recess formed in the rail to be freely restrained in a predetermined position within the baking chamber, the protrusion is formed by a front-rear claw piece formed by folding a loose piece formed in the notch. However, in such a structure, the strength of the part where the claw piece is formed is likely to be reduced to some extent due to the formation of the notch, and therefore, the part where the claw piece is formed tends to lose some of its strength. Generally, extending reinforcing ribs are formed, which has the disadvantage of requiring time and effort to manufacture.

(Problems to be Solved by the Invention) The object of the present invention is to provide a cooking device that is free from such inconveniences, that is, a cooking device that does not particularly require the formation of reinforcing ribs.

(Means for Solving the Problems) The present invention provides a pair of left and right guide rails in a firing chamber equipped with a gas burner or other heat source, and
A frame casing is supported on the rail by a pair of left and right flanges so as to be freely drawn out forward, and the frame casing is engaged with a concave part formed in the rail on each side with a convex part formed on each side of the frame casing. In a type that can be freely stopped at a predetermined position within the firing chamber, the convex portion is constituted by a protrusion having a substantially V-shaped cross section that extends to the rear of the through hole in the front.

(Example) Embodiments of the present invention will be explained with reference to attached drawings.

In the drawings, reference numeral 1 denotes a main body of the cooking device, and a pair of left and right guide rails 4, 4 are provided in a baking chamber 3 having a gas burner and other heat sources 2 inside the main body 1, and on the rails 4, 4, there are provided a pair of left and right guide rails 4, 4 on both sides of the upper end. a pair of flanges 5,
An enameled frame casing 7 supported by a frame 5 and housing a grill 6 and the like therein is provided so as to be freely drawn out through a front opening 8, and furthermore, the frame casing 7 is supported by a convex portion 9 formed on each side thereof. It was made to engage in the recesses 10 formed in the rails 4 on each side, so that it could be freely stopped at a predetermined position within the baking chamber 3. In the drawings, reference numeral 11 indicates a door that can be opened and closed to close the opening 8.

Although the above is not particularly different from the conventional one, according to the present invention, the convex portion 9 has a substantially V-shaped cross section that continues to the front through hole 9a and extends to the rear, as shown in FIG. 3, for example. It is constructed of a press-formed protrusion 9b, and a locking surface 9c in a substantially vertical plane is formed on the front end surface thereof.

In this case, the recess 10 is not particularly different from that of the conventional one, and is composed of a U-shaped groove, and its front edge 1
0a to engage with the locking surface 9c. In the illustrated embodiment, the protrusion 9b has a shape that gradually increases in width and height toward the front.

The convex portion 9 may be formed within the width of the flange 5 as shown in the figure, or may be formed at an inner corner thereof as shown in the fourth figure.

(Function) The operation is not particularly different from that of the conventional one, and the frame housing 7 moves between the convex portion 9 and the concave portion 10 during cooking.
The convex portion 9 is engaged with and held in a predetermined position within the firing chamber 3, but in this case, the convex portion 9 consists of a protrusion 9b extending rearward in succession to the front through hole 9a, as described above. The front end surface is a locking surface 9 in a substantially vertical plane.
The recess 1 is formed of a U-shaped groove, for example.
0, and the convex portion 9 does not require the formation of a large cut portion when forming the convex portion 9, so that its strength is not impaired.

(Effects) According to the present invention, the convex portion 9 is constituted by a substantially V-shaped protrusion 9b at the rear which is continuous with the through hole 9a at the front, and a good engagement surface is provided on the front end surface of the protrusion 9. 9c can be obtained, and the strength of the frame casing 7 is not significantly impaired during its formation, and thus separate reinforcing ribs and the like can be omitted, which has the effect of simplifying and inexpensively manufacturing the frame casing 7.
