Description

  The present invention relates to a gas stove that can be used by being mounted on a countertop, and can be used as a tabletop stove by being detached from the countertop.

  The drop-in type stove has a stove body in which a gas burner is accommodated and dropped into a stove installation opening formed in the counter top, and is further mounted on the top of the counter top so as to cover the top of the stove body. Is mounted (see, for example, Patent Document 1).

  On the other hand, there is known a gas stove that is not only usable as a drop-in stove, but also can be used as a tabletop stove by being detached from the countertop as required (see, for example, Patent Document 2). In this case, the top plate is connected to the upper portion of the stove body so that it can be easily detached from the counter top. In addition, this type of stove body is generally formed of a steel or stainless steel plate.

  However, when used as a drop-in stove, there is no problem because the stove body is dropped into the countertop stove opening, but when used as a desktop stove, the hot stove body is exposed, so the stove body When the user touches, there is a risk of discomfort due to heat.

  Therefore, in Patent Document 2, when used as a desktop stove, a cosmetic case that covers the stove body is attached so that the user does not directly contact the stove body.

Japanese Patent Laying-Open No. 2005-3288 (FIG. 2) Japanese Utility Model Publication No. 56-41135

  However, in the thing of the said patent document 2, whenever it uses as a tabletop stove, a decorative case must be mounted | worn to a stove body, The operation | work is troublesome. For this reason, not only usability is bad, but it is also considered that it is used as a tabletop stove without wearing a cosmetic case.

  Also, if the stove body is covered with a decorative case that is a separate member from the stove body, the heat dissipation effect of the stove body cannot be obtained sufficiently, and if the temperature of the stove body becomes excessively high, the shape of the stove body is distorted by heat. In addition, the stability may deteriorate when used as a desktop stove. Alternatively, when the temperature of the stove body becomes excessively high, the gas cock, electrical parts, and the like housed inside the stove body may be affected by heat, which is not preferable.

  In addition, this type of gas stove has insufficient heat dissipation from the stove body, and since the heat from the top plate is transmitted to the stove body and dispersed to reduce the temperature of the top plate, the top plate is extremely May become hot.

  In view of the above points, the present invention can reduce the influence of heat by suppressing the temperature rise of the stove body, and is preferably used in both cases where it is mounted on a countertop and a tabletop stove. An object is to provide a gas stove that can be used.

  The present invention includes a stove body that accommodates a gas burner therein, and a top plate that has a burner opening corresponding to the gas burner and closes the top of the stove body, and the top plate is exposed on the countertop. The stove body is detachably attached to the counter top by dropping it into a stove installation opening formed in the counter top, and the top plate is integrally connected to the upper part of the stove body. In the gas stove that can be used as a tabletop stove by removing the stove body from the above, the stove body is formed into a cylindrical shape by abutting a strip-shaped aluminum extrusion molding material at both longitudinal ends thereof A bulging portion that is formed on the entire periphery of the upper end portion and bulges so as to be hookable around the periphery of the opening for stove installation, A top plate holding portion that is formed inside the protruding portion and integrally holds the top plate, and a peripheral wall portion that is integrally connected to a lower end of the bulging portion, and the top plate holding portion includes: An abutting portion that protrudes from the upper end toward the inside of the stove body and abuts on the top surface of the top plate, and is formed below the opposed portion so that the top plate can be attached to the top plate holding portion. And an opening portion to be provided.

  The gas stove of the present invention is detachably attached to the counter top by hooking a bulging portion around the periphery of the opening for installing the stove on the counter top. And, the gas stove of the present invention has a stove body that is formed into a cylindrical shape by an extruded material made of aluminum in the form of a strip plate, for example, compared to a conventional stove body that is made of a plate material made of steel or stainless steel, for example. Therefore, the heat dispersion action and the heat dissipation effect are extremely high. In addition, the use of the aluminum extrusion-molded material makes it possible to use the stove body stably on the table because the occurrence of distortion in the stove body is extremely small. In addition, since an extrusion molding material may be called a pultrusion molding material, in this invention, a pultrusion molding material shall also be included.

  Further, the stove body of the present invention attaches the top plate to the contact portion from below the top plate holding portion through the open portion when the top plate is attached to the top plate holding portion formed at the upper end portion thereof. Make contact. A fixing member for fixing the top plate can be attached to the open portion. As the fixing member, for example, the top plate can be fixedly held on the top plate holding portion by filling the open portion with caulking material. it can. By adopting such a structure, it is not necessary to divide the stove body into a plurality of parts, thereby preventing an increase in the number of parts and a decrease in strength.

  Also, the top plate is usually heated by the radiant heat of the burner, but the contact portion formed on the top plate holding portion is in contact with the top surface of the top plate, so that it is transmitted from the top plate to the stove body. The heat is efficiently transmitted and distributed over the entire circumference of the peripheral wall portion of the stove body, and is further dissipated by a relatively large area in the peripheral wall portion. Thereby, not only can the top plate be prevented from becoming extremely hot, but also the heat transferred to the stove body can be efficiently dissipated to suppress the temperature rise of the stove body.

  Further, in the present invention, since the bulging portion is provided in the stove body, a vent hole that allows ventilation between the outside and the inside of the stove body can be formed in the bulging portion. The bulging portion is exposed on the counter top by being hooked on the periphery of the stove installation opening of the counter top. Thereby, combustion air can be smoothly supplied to the gas burner accommodated in the inside of the stove body via the bulging portion.

  In the present invention, it is preferable that a hanging wall that hangs down from a lower surface of the bulging portion is provided continuously with the bulging portion of the stove main body with a gap outside the peripheral wall portion. According to this, since the strength of the bulging portion can be improved by the drooping wall, the bulging portion is hooked on the outer periphery of the countertop stove installation opening via the drooping wall, and the gas stove The load can be firmly supported.

  In the present invention, the stove body is detachably provided with a support member that is interposed between the bulging portion and the counter top and supports the bulging portion, and the supporting member includes the counter top. A seating portion that is seated on an upper surface along the stove installation opening, and a standing wall that stands up from the seating portion and enters the space between the hanging wall and the peripheral wall portion.

  By providing the support member, for example, water spilled on the counter top can be blocked by an upright wall, and water or the like can be prevented from entering the stove installation opening. Also, the size of the existing stove installation opening formed on the countertop does not match the shape of the stove body, and a gap is created between the inner periphery of the stove installation opening and the bulge of the stove body In other words, by forming the seating portion to a size that covers the gap, it is possible to attach the gas stove to the existing stove installation opening that does not match the size without any trouble.

The lower part of the second contact part 18 (the lower part facing the first contact part 17) is open, and the open part 19 is filled with a caulking material 20 for bonding and fixing the top plate 6.

  Further, as shown in FIGS. 2 and 3, a plurality of vent holes 21 are provided at predetermined intervals with the side surface portion 15 of the bulging portion 9 being opened to allow ventilation. The vent 21 can be selectively disposed on the side surface 15 on the front, rear, left and right sides of the bulging portion 9, or on the side surface portion 15 on either side of the bulging portion 9. In order to improve the appearance by making it difficult to visually recognize the vent hole 21, the vent hole 21 can be provided only on the side surface portion 15 of the bulging portion 9 located on the back side of the stove body 5.

  Further, as shown in FIG. 3, a ridge 22 protruding upward is formed along the boundary between the upper end of the peripheral wall portion 8 and the lower surface portion 14 of the bulging portion 9. The ridges 22 can block water and the like that has entered the inside of the bulging portion 9 from the vent 21, so that water and the like can be prevented from entering the stove body through the vent 21. .

  The stove body 5 is formed of an extruded material made of a strip-like aluminum alloy. That is, a strip including the peripheral wall portion 8, the bulging portion 9, the bottom plate connecting portion 11, and the top plate holding portion 12 is formed by extrusion molding from an aluminum alloy material. As shown in FIG. A square tube-shaped stove body 5 is formed by bending the two ends 5a and 5b into a substantially quadrangular ring shape. The abutting portions of both end portions 5a and 5b are joined by a joint member, welding, or the like, although not shown. Note that the vent hole 21 is formed at an appropriate position after the extrusion molding and in the previous step of bending into a square tube shape.

  When assembling the top plate 6 to the square tube-shaped stove body 5, referring to FIG. 3, prior to attaching the bottom plate 10 to the stove body 5, the top plate 6 is inserted into the stove body 5 from below, The top plate 6 is brought into contact with the first contact portion 17 and the second contact portion 18 through the opening portion 19 of the top plate holding portion 12. Thereafter, the caulking material 20 is filled in the open portion 19, whereby the top plate 6 is maintained in a state of being firmly held by the top plate holding portion 12. Thus, when the top plate 6 is attached to the top plate holder 12 of the stove body 5, the top plate 6 can be mounted from the lower side of the top plate holder 12 through the opening portion 19, so the stove body 5 Need not be divided into a plurality of parts, and an increase in the number of parts and a decrease in strength can be prevented.

  The top plate 6 is formed in a flat plate shape using heat-resistant glass or metal, and as shown in FIG. 1, burner heads 23, 23 are connected to the upper part of the burner body housed in the stove body 5 to form a flame. Is exposed on the top surface. On the top plate 6, the virtues 24 and 24 are placed so as to surround each burner head 23, and operation knobs 25 and 25 for each burner are arranged on the front side of the top plate 6.

This prevents the occurrence of gas supply failure due to extreme bending of the gas hose H when used as a tabletop stove.

  As described above, the gas stove 1 of the present embodiment is formed of, for example, a steel plate or a stainless steel plate because the stove main body 5 is formed in a tubular shape by the strip-shaped aluminum extrusion molding material. Compared to the conventional stove body, the heat dispersing action and heat dissipation effect are extremely high.

  The top plate 6 is heated by the radiant heat of the flame formed on the outer periphery of the burner heads 23, 23. As shown in FIG. 3, the first contact portion 17 of the top plate holding portion 12 is By being in contact with the upper surface, the heat transmitted from the top plate 6 to the stove main body 5 is efficiently transmitted and distributed over the entire circumference of the peripheral wall portion 8 of the stove main body 5, and the peripheral wall portion 8 has a relatively large area. Heat is dissipated. Thereby, not only can the top plate 6 be prevented from becoming extremely hot, but also the heat transmitted to the stove body can be efficiently radiated to suppress the temperature rise of the stove body 5. Therefore, since the distortion of the stove body 5 is extremely small due to the influence of heat, it can be used stably on a table. Further, since the peripheral wall portion 8 of the stove body 5 has good thermal conductivity, when the user touches the stove body 5, discomfort due to heat can be reduced.

  Further, when the stove main body 5 is mounted on the countertop 2, if the airtightness inside the system kitchen is high, the supply of combustion air to the burner main body housed inside the stove main body 5 may be insufficient. Though possible, external air can be taken into the stove body 5 as combustion air through the vent 21 formed in the bulging portion 9 as in the present embodiment, so that the burner is burned well. be able to.
