Description

  The present invention relates to a gas stove.

  Conventionally, a gas stove including a top plate made of a flat plate made of glass or metal is known (for example, see Patent Document 1). Some gas stove top plates are made of sheet metal press-molded products, but recently, top plates made of glass or metal flat plates have become popular. This top plate has a flat upper surface and is excellent in cleanability and appearance.

  Moreover, in the gas stove using the top plate comprised with such a flat plate, in order to show the upper surface of a top plate widely, five virtues are formed compactly and are mounted on the top plate.

JP2007-285613

  However, in the configuration where the virtues are placed on the top plate, if a relatively heavy pan or the like is placed on the virtues, the load received by the virtues concentrates on a part of the top plate, and the top plate is distorted. . In particular, Gotoku is placed on the top plate so as to surround the stove opening formed on the top plate corresponding to the stove burner, so that distortion near the stove opening is smaller than the outer peripheral side of the top plate. growing.

  And if the top plate is distorted in the vicinity of the stove opening, the virtues will tilt along the direction of the top plate distortion, and the flame of the stove burner will not hit the pan bottom evenly, and the goboku claws may be struck. There is a risk of lowering the combustion efficiency.

  In this type of gas stove, generally, a beam member is bridged between the left and right side walls of the stove body, and the burner body of the stove burner is supported on the beam member.

  However, in the case where the stove burner includes a mixing tube extending from the burner body, the mixing tube side is easily swung easily only by supporting the burner body on the beam member. When the gas supply pipe provided with a nozzle for injecting fuel gas is a relatively hard copper pipe, the gas supply pipe is connected to the end of the mixing pipe and the nozzle is provided at the end opening of the mixing pipe. When the gas pipes face each other, the mixing pipe may be inclined due to the influence of the pipe shape or pipe length of the gas supply pipe. When the mixing tube is inclined, the cono burner is inclined with respect to the top plate. This also causes the flame of the cono burner to not uniformly hit the bottom of the pan, and the combustion efficiency of the cono burner may be reduced by hitting the five virtue claws.

  In view of the above points, an object of the present invention is to provide a gas stove that can prevent the inclination of the stove burner and at the same time prevent the top plate from being distorted by a load and suppress the reduction in the combustion efficiency of the stove burner. To do.

A supported burner body, a mixing pipe extending from the burner body and introducing a mixed gas of fuel gas and primary air into the burner body, and provided on the top of the burner body through the stove opening on the top plate And a burner head having a plurality of flame holes on the outer periphery, a second support member for supporting the burner body on the stove body via the mixing tube is provided, Of the support member, said the back surface of the top plate corresponding to the inside of the circumscribed circle of the trivet contact provided table support portion for supporting the top plate, a pair of the stove burner to the stove body is accommodated, A pair of the stove openings are formed in the top plate, the mixing tubes of both the stove burners are arranged in the left-right direction and extend in the front-rear direction, and the second support member is provided between the mixing tubes of both the stove burners And both mixing tubes are supported together .

  The burner body is not only supported by the first support member (for example, a beam member spanned between the left and right side walls constituting the stove body), but also includes a mixing tube provided extending from the burner body. And is also supported by the second support member. As a result, the mixing tube can be made non-oscillating, and the combustion efficiency of the stove burner can be prevented from being lowered due to the tilt of the stove burner with respect to the top plate.

  Furthermore, the top plate support portion provided on the second support member abuts against the back surface of the top plate and receives a load applied to the top plate from below. Thereby, the concave deformation | transformation of the top plate to the inside of a stove main body by the load provided to the top plate is prevented. At this time, the top plate support portion abuts the back surface of the top plate corresponding to the inside of the circumscribed circle of the virtues, so that when a relatively heavy pan or the like is placed on the virtues, a load from the virtues is obtained. This load can be supported at a position where it is easy to concentrate, and distortion of the top plate can be prevented efficiently and reliably.

  Furthermore, by providing the top plate support portion on the second support member, a single member can be obtained, and both the inclination of the cono burner and the distortion of the top plate are prevented without increasing the number of parts. can do.

Furthermore , since the second support member supports the mixing tubes of both the stove burners at the same time, it is possible to prevent misalignment between the stove burners.

Moreover, in this invention, it is preferable to provide the top-plate support member which contact | connects the back surface of the said top plate corresponding to the center part between both said stove main bodies, and supports this top plate.

  When a relatively heavy pan or the like is placed on both virtues provided for both stove burners, the load is concentrated in the center between the stove openings, and the center is in the direction of the stove body. There is a risk of deformation. Therefore, by providing the top plate support member, the top plate support member abuts on the back surface of the top plate corresponding to the central portion between the two stove openings, and the distortion of the central portion between the two stove openings in the top plate is achieved. Can be reliably prevented.

  When the stove body is provided with a grill cabinet, and the stove burner is adjacent to the grill cabinet, the second support member is connected to the outer surface of the upper wall of the grill cabinet, and the grill cabinet The burner body is preferably supported on the stove body via

  As a result, the second support member is connected to the outer surface of the upper wall of the grill cabinet located relatively close to the top plate, so that the second support member can be formed compactly and has sufficient strength. It is possible to reduce the size and weight while ensuring.
