Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a three-port gas stove or a four-port gas stove in a system kitchen.
The present invention relates to an aluminum sheet stove mat used in combination with a gas stove provided with four or four gas burners.

[0002]

2. Description of the Related Art Conventionally, for example, in the structure of a three-necked gas stove, a burner head is provided on both sides of the front half of the saucer and a central portion of the latter half, and one side part of the first half and one side of the latter half of the saucer. There is a burner head provided in and, but in any case, on the saucer of the gas stove provided with these burner heads, as an aluminum sheet stove mat laid to prevent contamination due to broth etc., Conventionally, three rectangular mats each having an exposed hole for a burner head in the central portion and having a circumferential groove around the exposed hole that can be fitted into a saucer portion around the burner head are used. Each mat is individually laid on the saucer according to the corresponding burner head, or for the first half of the saucer, an oblong rectangular shape is provided on both sides with exposure holes that match the burner heads on both sides. State It is configured so as to lay a piece of stove mat.

[0003]

However, in the three-necked gas stove of the system kitchen, the size between the left and right burner heads provided on both sides of the first half of the saucer differs depending on the model, and is the smallest. There is a difference of about 60 mm in width from the largest one. for that reason,
If the mats that were separately laid on the left and right burner heads as in the former are formed to a size that fits smaller models, a gap will be created between the mats when laying on a large model gas stove. There is a problem that part of the saucer is exposed to the outside through the gap, which not only impairs the appearance but also stains it with broth or the like.

Further, if the mat is formed in a size suitable for a large model, when it is laid on a gas stove of a small model, the outer end of the mat sticks out from the periphery of the saucer of the gas stove and becomes invisible. However, there were problems such as unstable installation. Therefore, it is sufficient to form several kinds of mats according to the size of the model, but this not only increases the cost, but in many cases the purchaser does not remember the size of the gas stove used. In addition, new problems arise such as the case of purchasing different models.

On the other hand, even in the case of a single oblong oblong stove mat having exposure holes on both sides adapted to the burner heads on both sides, the size between the exposure holes cannot be changed. It is necessary to manufacture several kinds of mats each having a size suitable for a gas stove of a large size, which causes the same problem as described above.

The present invention has been made in view of the above problems, and an object of the present invention is that the gas stoves of the above-mentioned large and small models can be laid accurately and clearly, and the laying can be performed easily, and the saucer of the gas stove can be easily installed. It is intended to provide a stove mat which can be completely covered with broth to prevent stains caused by broth and the like.

[0007]

In order to achieve the above object, a stove mat according to the present invention is provided with one or two gas burners in the rear half of the pan and two gas burners in the front half with a predetermined interval in the left-right direction. A gas stove mat having a gas burner, the mat body laid on each of the gas burner portions has an exposure hole for exposing the burner head, a receiving groove portion fitted in a saucer portion around the burner head, and a receiving groove portion. The left and right mat bodies, which are made up of horizontal flanges that are connected to the upper end of the peripheral wall of the groove and are laid on both sides of the first half of the tray, have their inner facing edges integrally connected by a bendable portion that can be expanded and contracted. It has a structure.

In the stove mat having such a structure, according to the invention described in claim 2, the stretchable bending portion has a length equal to the side length of the opposing horizontal flange portions of the left and right mat bodies, and It is formed by a rectangular flap body having a V-shaped cross section in which the central part is bent downward over the entire length, and the outer edges of the flap piece parts on both sides are bendable to the opposing horizontal flange parts of the left and right mat bodies. According to the invention described in claim 3, in the left and right mat bodies, at least one mat body is formed by extending the outer edge portion at the rear end rearward of the gas stove. It is characterized in that it is formed into a flat L-shaped mat body formed in an auxiliary receiving groove portion laid on the latter half of the tray.

[0009]

[Function] The left and right mat bodies are laid on the pan portions around the burner heads provided on both sides of the front half of the pan of the three-port gas stove. At this time, since the opposing inner end edges of the left and right mat bodies are continuously provided by the bent portions that can be expanded and contracted in the left and right direction, these left and right mat bodies are provided between the left and right gas burners provided on both sides of the first half of the saucer of the gas stove. It can be laid at the same time while adjusting the expansion and contraction in the left-right direction according to the dimensions. Therefore, it can be adapted to large and small gas stoves.

In addition, when the exposed holes formed in the left and right mats are placed on the burner ports of the corresponding gas burners and pushed down onto the pan, the expansion and contraction of the bent portion allows the exposed holes to be accurately and easily burned. Fits in the mouth. In this way, the front half of the saucer of the gas stove is entirely covered by the laying of the left and right mat bodies, and the saucer is well covered with the mat body laid at the rear end of the saucer to prevent stains due to broth or the like. In the four-port gas stove, the left and right mat bodies may be arranged before and after the saucer.

When the left and right mat bodies are connected to each other so as to be expandable and contractible in the left and right direction, the bent portion has a V-shaped cross-section, the expansion and contraction action can be improved. If it is done smoothly and one of the mat bodies is oriented in the width direction of the gas stove, the other mat body will naturally orient precisely in the same direction and the laying operation can be easily performed. From left to right mat body back to back,
That is, the horizontal flanges can be overlapped with each other in a joined state to be compact.

Further, as described in claim 2, at least one of the left and right mat bodies is laid on the rear half of the saucer of the gas stove with the outer edge of the rear edge thereof being extended rearward. Plane L formed in the auxiliary receiving groove
If it is formed in a V-shaped mat body, not only can the mat body laid on the latter half of the saucer be downsized, but if only one is formed in a plane L-shaped mat body, the latter half of the saucer can be formed. The mat body to be laid on top has a structure that can fit both a three-port gas stove with a gas burner in the center of the latter half of the saucer and a three-port gas stove with a gas burner on one side. You can keep it.
