Abstract

PROBLEM TO BE SOLVED: To prevent the occurrence of the crack of an artificial marble counter by setting the space width between the front side inner peripheral surface of the opening of the counter of a cooking stove table and a gas cooking stove body to a specific size or more. SOLUTION: A space S is provided between the inner peripheral surface 2b of the opening 2b of the artificial marble counter 2 of a gas cooking stove 5 and a gas cooking stove body 5a. The width size (d) of the space S at the front side of the counter 2 is so set as to become 20mm or more. Thus, at the time of normally using the stove 5, the temperature rise of the front side area of the counter 2 can be suppressed. The sheet made of a heat insulation tape or foamable material such as aluminum is, for example, laminated on the inner peripheral surface 2b of the opening of the counter 2 to form a heat insulation layer 10, and the absorption efficiency of the radiation heat from the surface 5a of the body 5a is lowered. Thus, the occurrence of the crack of the counter 2 can be prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a stove top having an artificial marble counter.

[0002]

2. Description of the Related Art A stovetop, which is used as a component of a system kitchen or installed in the kitchen as an independent cooking facility, usually has a counter at the top and a gas stove at the opening formed in the counter. It has a structure in which a heating device is installed facing the above. There is also one that incorporates a grill, gas oven, microwave oven, etc. under the stove.

[0003]

[Problems to be Solved by the Invention] When the counter of the stove is made of artificial marble manufactured by a casting method,
There is a problem that the counter repeatedly expands and contracts due to the heat history of temperature rising and cooling accompanying the use of heating equipment, and as a result, cracks are generated particularly in the four corners of the opening after continuous use for a certain period or longer. The occurrence of cracks is observed as early as 2-3 years.

The cause of the cracks is mainly that the counter is heated to a considerably high temperature by the use of a heating device. In addition to that, since the heating state of the counter varies depending on the part, the degree of expansion becomes non-uniform and the strain is distorted. It may occur at the counter. To explain this in detail, a plurality of stoves are usually arranged on the stove stand, and the use frequency of each stove is different. In particular,
In general, the stove on the front side is used more frequently than the stove on the back side, and when the stove table and the cooking table are adjacent to each other, the stove closer to the cooking table is used more frequently. Therefore, the front area of the counter and the area near the stove near the counter are often heated to relatively high temperatures, while the area behind the counter and the area near the stove far from the counter are hot. The difference is that the number of times of heating is relatively small, which is a factor that causes the above-mentioned distortion.

Even with the same artificial marble counter, cracks are less likely to occur with the press molding method, so it is conceivable that the artificial marble product with the cast molding method is slightly inferior in the fineness of the structure. Therefore, overcoming the above-mentioned drawbacks in the product by the casting method suitable for molding a complicated shape is extremely important for increasing the commercial value.

[0006]

The feature of the means adopted by the present invention to solve the above-mentioned conventional drawbacks in the cooktop is that a heating device such as a gas stove is arranged in the opening of the counter made of artificial marble. In the stove stand, the space width between the front inner peripheral surface of the counter opening and the heating device is set to 20 mm or more.

Further, in order to enhance the effect of preventing the temperature rise of the counter, it is possible to adopt a structure in which a heat insulating layer is formed on the inner peripheral surface of the counter opening.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A case where the present invention is applied to a gas stove, which is the most common stove top, will be described. In a gas stove, a gas stove is placed as a heating device in an opening formed in a counter at the top of a cabinet. A space is provided between the side surface of the stove body and the inner peripheral surface of the opening of the counter so that they do not come into contact with each other. The top plate on the top of the stove main body has a flange on its periphery that covers the gap between the counter opening and the stove main body.This flange contacts the surface of the counter through the seal packing attached to the tip. Touching.

The burner portion of the gas stove is usually arranged in front of the counter in consideration of usability. A stove top frame is installed above the burner so that cooking utensils such as pots and pans can be placed.

In addition, a grill, a gas oven, a microwave oven, or a model that combines these is often installed in the lower part of the gas stove.

In order to suppress an excessive temperature rise of the counter when using the gas stove, a space is provided between the inner peripheral surface of the opening of the counter and the side surface of the main body of the stove so that the two do not come into direct contact with each other. In the present invention, the space width between the front inner peripheral surface of the opening of the counter and the front surface of the stove body is set to 20 mm or more, preferably 20 to 29 mm, and more preferably 24 to 26 mm. Conventionally, the space width is less than 20 mm, and most of it is 10 mm or less.

As the space width on the front side of the counter and the main body of the stove is expanded more than the conventional one, the space width on the rear side is narrowed to the contrary. For this reason, when the gas stove is used, the temperature rise in the front area of the counter is suppressed, and on the contrary, the degree of temperature increase in the rear area is slightly increased, so that the temperature difference in the entire counter is reduced. As a result, the unevenness of the expansion degree of the counter is reduced, and the generation of strain, which is the main cause of cracks, can be prevented. Therefore, even if the artificial marble counter is manufactured by a casting method that is excellent in moldability as compared with the press-molded product but is slightly inferior in the denseness and strength of the structure, there is no possibility of causing cracks.

By the way, in order to enhance the effect of preventing the temperature rise of the counter, a heat insulating layer may be formed on the inner peripheral surface of the counter opening. As means for forming the heat insulating layer, for example, a heat insulating tape that reflects radiant heat such as an aluminum tape is attached, or a thin plate or sheet made of a foamable material is attached,
It is conceivable to apply a foaming paint. By forming a heat insulating layer on the inner peripheral surface of the counter opening,
Since the efficiency of absorbing the radiant heat emitted from the gas stove is reduced, the temperature rise of the counter when using the gas stove can be reduced.

In addition to the gas range described above, the present invention can be applied to a stove top using an electric stove, a hot plate, an electromagnetic cooker or the like as a heating device.
