DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grille for supporting an object to be cooked, such as a fish, when heating the object, and more particularly to a grille used for a grill.

[0002]

2. Description of the Related Art A grill of this type is used, for example, in a grill integrated with a gas stove when cooking with a grill burner provided on the ceiling and side walls of the grill. It is used to support objects to be cooked. As shown in FIG. 6, the conventional grill 5 is a wire 51 having a circular cross section in order to reduce costs and facilitate handling.
a, and a mounting portion 52 in which a plurality of circular wires 52a having a circular cross section are erected in a range surrounded by the frame portion 51.
It is composed of Each wire 52a is fixed to the upper surface of the frame 51 by, for example, spot welding.

Here, when a wire having a circular cross section is used as a wire constituting the frame portion 51 and the mounting portion 52, the frame portion 51
When dirt such as grease adheres to a small gap formed by the upper surface of the wire 51a of the frame portion and the outer peripheral surface of each wire 52a in the vicinity of each fixed portion where each wire 52a is spot-welded to the It is often difficult to completely remove the dirt, and the dirt accumulates around the fixed portion. Then, with the use of the grill, the weld 5
No. 3 corroded and came off, resulting in poor durability.

[0004] In order to solve such a problem, Japanese Patent Application Laid-Open No. H11-346932 discloses a grill which is welded by bringing an end face of a wire constituting a mounting portion into contact with an inner surface of a frame portion. However, in this case, the end face of the wire must be accurately brought into contact with the inner side surface of the frame portion, and the positioning and dimensional control therefor are troublesome and costly.

In the case of using a wire having a circular cross section,
Due to the weight of the object to be cooked, the contact area of the object to be cooked with the outer peripheral surface of each wire 52a constituting the mounting portion 52 increases, so that the cooking of the object to be cooked is completed and the object to be cooked is removed from the grill. In some cases or when the object to be cooked is turned upside down during cooking, the object to be cooked adheres to the grill, and the object to be cooked sometimes collapses.

[0006]

In this case, it is proposed that the grill is subjected to a surface treatment, for example, such as a fluororesin, in order to protect the welded portion and to prevent the food to be attached to the grill. (Japanese Unexamined Patent Publication No. 5-313337)
In this case, the production cost of the grill is high. On the other hand, it has been proposed to lay an aluminum mat having irregularities on its surface in a grill at the time of cooking (for example, see Japanese Utility Model Publication No. Sho 62-31770). It cannot be used for a double-sided grill that heats and cooks an object from below the grill at the same time as heating the object.

Accordingly, the present invention can be used for a double-sided grill, can be manufactured at low cost, has a structure that is easy to care for, and it is difficult for dirt to accumulate at the fixing portion of the wire, and the durability of the grill is improved. In addition, it is an object of the present invention to provide a grill which is difficult to adhere to an object to be cooked during cooking.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a method for forming a mounting portion by forming a plurality of wires on a frame portion within a range surrounded by the frame portion. In a grill net on which a cooking object such as fish is placed, the frame and each wire come into surface contact at least at the location where each wire is fixed to the frame, and the upper surface of the frame to which the wire is fixed The frame portion and each wire are formed such that the outer angle between the wire and the side portion of the wire is 90 degrees or more.

According to the present invention, since no gap is formed at each fixing point of the wire constituting the mounting portion to the frame portion, dirt hardly accumulates in the periphery thereof, and corrosion associated with use does not progress.
In addition to the fact that the wires are fixed in surface contact with the frame, the durability of the grill is improved, and since no special surface treatment or the like is required, the production cost can be reduced and the grill is double-sided. Can also be used.

Further, if a wire having a circular cross section is used as the wire constituting the mounting portion, the weight of the object to be cooked increases.
The contact area of the object to be cooked with the outer peripheral surface of each wire becomes large, and the object to be cooked easily adheres to the grill during cooking. Here, if the upper surface portion of each wire is formed in a shape having an upwardly convex corner, the contact area of the object to be cooked with the outer peripheral surface of each wire can be made smaller than that having a circular cross section, and the cooked material can be cooked during cooking. This is advantageous in that objects are less likely to adhere to the grill. In this case, it is preferable that each wire has a substantially triangular cross-sectional shape in order to reduce the work and processing cost of the wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a gas stove 1 has two stove burners 12 provided so as to face an opening 11a of a top plate 11, and the operation of the stove burner 12 is controlled by a front panel at both ends. 13 is controlled by an operation button 14a and a heating power adjustment lever 14b. The grill 2 for cooking foods such as fish is integrated into the gas stove 1 at the center, that is, between the front panels 13 at both ends.

The grill 2 has a substantially rectangular parallelepiped shape and includes a grill 21 made of steel. An exhaust pipe communicating with an exhaust port 16 provided on the top plate 11 of the gas stove 1 is provided on the rear side of the grill storage 21. An upper fire burner is provided on the ceiling of the grill storage 21, and on both inner side walls of the grill storage 21, left and right lower fire burners 22 which are located below a grill, which will be described later, face their flame outlets. It is provided.
Here, the upper fire burner is constituted by a Schbank type burner having a plurality of ceramic plates provided with a plurality of gas outlets penetrating therethrough. The left and right lower fire burners 22 are constituted by Bunsen type burners in which a plurality of flame openings are arranged. The operation of both the upper and lower burners is also controlled by the operation button 15a and the heat control lever 15b attached to the front panel 13. A grill door 23 in which heat-resistant glass is fitted is detachably mounted on the open front surface of the grill storage 21. The grill door 23 includes a frame member 23a.
Plays a role in supporting the grill plate 3 described later and moving the grill plate 3 in and out of the grill storage 21 as the grill door 23 opens and closes. The grill plate 3 for storing broth such as fat and water generated when cooking a food such as fish on the grill is made of a thin steel plate having a substantially rectangular plate shape and a substantially horizontal brim portion 31 around the plate. After being press-formed so as to be formed, a finish coating such as an enamel is applied.

Referring to FIG. 2, the grill 4 supported by the grill plate 3 includes a frame 41 made of a wire 41a,
And a mounting portion 42 in which a plurality of wires 42a are erected at predetermined intervals in the longitudinal direction of the mounting portion 42. Each of the wires 4 constituting the mounting portion 42
2a is joined to the upper surface of the wire 41a constituting the frame 41 by, for example, spot welding. A grill support 43 extending in a direction perpendicular to the mounting surface of the mounting portion 42 is joined to the front and rear wires 41a of the frame portion 41 by, for example, spot welding. Thus, the grill net 4 is stored in the grill storage 21 together with the grill dish 3 with the opening and closing of the grill door 23 by placing the grill net support 43 on the front and rear flanges 31 of the grill dish 3, An object to be cooked such as fish is held at a predetermined height position in the grill storage 21.

When a wire having a circular cross section is used for the frame portion 41 and the mounting portion 42 as in the prior art, the upper surface of the frame portion and the outer peripheral surface of the wire are formed around the fixing portion. There is a problem that dirt such as oils and fats adheres and accumulates in the small gaps, and the locations corrode, thereby impairing the durability of the grill. Further, in this case, the contact area of the object to be cooked with each wire rod 42a is large due to the weight of the object to be cooked, and the object to be cooked easily adheres to the grill 4 during cooking. Therefore, in the present embodiment, the wire 41 forming the frame portion 41
a having a square cross section is used, and
As the wire 42a constituting the wire 2, a wire having a substantially regular triangular cross section was used. Each wire 42a of the mounting portion 42 is fixed to the frame portion 41 by spot welding in a state where the wires 42a of the mounting portion 42 are in surface contact with the upper surface of the wire 41a of the frame portion 41. As a result, there is no gap in the fixing portion 44 of the wire 42a constituting the mounting portion 42 to the frame portion 41. For this reason, it is difficult for dirt to accumulate around it, and corrosion associated with use hardly progresses. As a result, the durability of the grill 4 can be improved. On the other hand, the object to be cooked placed on the grill 4 is supported at the top corner of each wire 42a having a substantially equilateral triangular cross-section constituting the mounting portion 42, so that the wire 42a having a circular cross section is not used. Since the contact area of the object to be cooked becomes small, the object to be cooked hardly adheres to the grill 4. In this embodiment, each wire 42a has a substantially triangular cross section in order to facilitate the manufacture of the grill 4 and reduce the manufacturing cost. However, the present invention is not limited to this. The upper surface of 42a may have a shape having an upwardly convex corner. For example, as shown in FIG. 3, a pentagonal cross section may be used.
In this case, in order to reduce the contact area of each wire 42a with the object to be cooked, the upper surface portion of each wire 42a as viewed in the cross section of the wire is formed such that the angle of the top is about 120 degrees or less. Further, in order to prevent dirt from adhering and accumulating around the fixing portion 44 of each wire 42a, an angle α outside the wire 42a formed by the upper surface of the wire 41a of the frame 41 and the side portion 42b of the wire 42a. Was set to 90 degrees or more.

[0015] Further, during cooking, the object to be cooked is a grill 4.
In order to make it difficult to adhere to the
2a can also be formed as follows. That is, FIG.
As shown in FIG. 4A, a concave portion 42c may be formed at a predetermined interval at the top of a wire 42a having a substantially regular triangular cross section, or a wire 42 having a substantially regular triangular cross section as shown in FIG.
a may be curved like a wave. As shown in FIG. 5, the wire netting 42 a having a substantially regular triangular cross section may be alternately fixed to the upper and lower surfaces of the frame portion 41 by spot welding.
