Description

  The present invention relates to a grill of an oven toaster.

With respect to the grill net of this type of oven toaster, a net structure is known instead of a conventional wire rod arranged in parallel.
For example, there is a net having a mesh structure composed of a mesh part and a frame part shown in FIG. 1 of Japanese Patent No. 3760408 (Patent Document 1) “Oven Toaster”.

Japanese Patent No. 3760408

The grill structure having the above-described mesh structure is configured by fusing and integrating a frame portion with the periphery of the mesh portion to protect the periphery of the mesh portion. That is, since it is composed of a mesh part and a frame part of two or more parts, it requires two parts or more and requires fixing work of two parts or more, resulting in an increase in product cost.
In the known oven toaster shown in FIG. 15, the grill 10 has a configuration in which a plurality of conventional wire rods are arranged in parallel, and further, in order to move the grill net back and forth in conjunction with the door opening / closing mechanism of the oven toaster, A fixing protrusion 11 protruding in the direction is fixed to and integrated with the grill 10. The rear side 11a of the fixing projection 11 is fixed to the body via the spring 12, the front side 11b of the cylindrical projection 11 is fixed to the door 15 via the linkage 13, the rear side 11a of the fixing projection 11 and By passing the front side 11b of the fixing projection 11 through a longitudinal hole formed in the inner wall of the machine body, the grill 10 is supported in a substantially horizontal state.
An object of the present invention is to make the above-mentioned grilled net structure a single component, and in the fixed type grilled net, the fixing protrusion 11 is integrated with the grilled net.

  In the present invention, in the oven toaster grill, a mesh portion formed by pressing a metal flat plate, a plurality of cylindrical protrusions formed on both sides of the peripheral portion, and the peripheral portion, It has an edge winding part formed by edge winding processing except for a portion where the cylindrical projection part exists.

In the present invention, the mesh portion of the grill net is manufactured by pressing a metal flat plate, and the peripheral portion of the mesh portion is made to function as a frame portion by the edge winding process. By completing the product by press working and edge winding of a metal flat plate, there is an effect of eliminating the work of fixing two parts in the conventional process and reducing the product manufacturing cost.
Further, in the fixed type grill net, instead of the fixing projection, the cylindrical projection portion is integrated with the mesh portion, so that the fixing projection in the known grill net is equipped with two parts. It has the effect of eliminating the fixing work and reducing the product manufacturing cost.

The longitudinal cross-sectional view of the grill which has the rib-shaped projection part of 3rd Example of this invention. The schematic which shows the use condition of the grill of this invention in a longitudinal section. The perspective view which shows the grill net of a well-known oven toaster.

  The present invention will be described in detail based on the embodiment shown in FIGS.

  1 to 8, the grill A of the present invention has a rectangular mesh portion 1 in plan view, an edge winding portion 2 adjacent to the periphery of the mesh portion 1, and a part of the edge winding portion 2. And a plurality of cylindrical projecting portions 3 formed by cutting out the.

Below, the manufacturing method of the grill of this invention is demonstrated.
The metal flat plate B of the material shown in FIG. 9 is formed by cutting the mesh w in the central portion excluding the peripheral edge b, and forming the mesh portion 1 by a pressing process, and cutting off the portions C on both sides. The metal flat plate B1 shown in FIG.

  The metal flat plate B1 of the intermediate material has a shape having a flat plate strip portion bb on the left and right sides of the peripheral portion b. By cutting off the outer end c of the peripheral portion b, the tip of the flat plate strip portion bb It protrudes from the edges of the peripheral portions bL and bR.

Next, with respect to the peripheral portion b of the metal flat plate B, the edge winding portion 2 is formed by performing edge winding processing (curling processing) except for a partial section (flat plate strip portion bb),
Further, the plate-like strip portion bb of the peripheral edge portion b of the metal flat plate B is formed into a cylindrical shape by curling, thereby forming the cylindrical projection portion 3 protruding from the peripheral edge of the mesh portion 1 to the left and right sides.

Thus, the net A is completed by the metal flat plate B which is a single material.
This eliminates the need for a plurality of members and their fixing work in the conventional product grill.

  The edge winding part 2 eliminates the exposure of the edge of the mesh part, prevents accidents in which the user touches carelessly and damages the fingers, and increases the strength of the grill net A.

  In the examples, the thickness t of the metal flat plate B was set to 0.6 mm for the mesh portion, the square a for the side a = 7 mm was set for the mesh w, and the width d of the linear portion of the mesh portion 1 was set to 1 mm.

  The mesh w is a square in the embodiment, but may be a rectangle, a rhombus, a hexagon (tortoise shape), a round shape, or the like. Furthermore, as the shapes of the central portion and the peripheral portion are different, meshes of several kinds of shapes may be mixed.

  In the embodiment, the vertical part 4 is formed by adding a bending process on the back side, but may be omitted.

  FIG. 13 shows the use state of the grill A of the present invention, and is located in the heating chamber of the oven toaster, connecting the rear side 3a of the cylindrical projection 3 with the spring 12, and the front side of the cylindrical projection 3 3b is connected to the door 15 through the linkage 13.

  FIG. 11 shows a grill according to the second embodiment, in which a peripheral step portion 5 is formed around the mesh portion 1 by step pressing.

  FIG. 12 shows a grill according to a third embodiment, in which a plurality of rib-like protrusions 6 are formed in the center part of the mesh part 1 in the front-rear direction or in the left-right direction by pressing or ribning.

  The peripheral step portion 5 and the rib-like protrusion 6 have an effect of increasing the strength of the flat plate net A.

  An aluminum-plated steel plate is used as it is, surface treatment such as heat-resistant coating (black, brown, gray, etc.) on the steel plate and chrome plating on the steel plate is appropriate. The heat-resistant coating has good heat absorption, so the bread is baked well.

  The present invention contributes to sales promotion of an oven toaster by providing an inexpensive grill net.
