Description

  The present invention relates to a glass top plate for a drop-in type stove in which the stove body is disposed so as to drop into a stove opening established in a countertop.

  Conventionally, in this type of drop-in stove, a top plate is known that uses a glass top plate whose main portion (top plate main body) is made of glass because of its good appearance and cleanability (for example, Patent Document 1). This glass top plate is composed of a glass top plate main body and an outer frame surrounding the top plate main body, and the outer frame is composed of a front frame material along the front side of the top plate main body, and the top plate main body. The left and right side frame members along the left and right side portions and the rear frame member along the rear portion of the top plate main body are connected in a frame shape. In addition, in the drop-in type stove, in order to prevent the hot air in the stove body from reaching the counter top, the hermeticity of the stove body has been improved. In this state, sufficient combustion air is supplied to the burner in the stove body. become unable. Therefore, in the glass top plate, the rear frame material is arranged separately behind the top plate main body, the partition frame material is arranged along the rear side portion of the top plate main body between the left and right side frame materials, A vent opening communicating with the inside of the stove body is defined between the partition frame member and the rear frame member, and a hood portion extending rearward and upward is provided on the partition frame member so as to cover the vent hole from the front of the vent hole. Provided integrally. According to this, the opening area of the ventilation hole can be widened, and the combustion air can be sufficiently supplied into the stove body, and the ventilation hole is hidden behind the hood portion when viewed from the front, so that the appearance can be impaired. Furthermore, the hood portion prevents foreign matter such as spilled boiled juice or dust from falling into the vent hole.

  However, in the glass top plate, the outer frame surrounding the glass top plate main body is a front frame material along the front side portion of the top plate main body and left and right side frame materials along the left and right side portions of the top plate main body. And it will be comprised by five frame materials, a rear frame material and a partition frame material, and there exists a malfunction which increases a number of parts, requires an effort, and becomes high in cost. Moreover, since the entire periphery of the top plate main body is surrounded by the outer frame, there is a problem that the original refreshing feeling of glass is impaired.

  Therefore, a glass top provided with a frame body separate from the top plate main body only on the rear side of the periphery of the top plate main body, and provided with a vent and a hood portion covering the upper side of the vent on the frame. A plate is known (see, for example, Patent Document 2). In this case, a silicone caulking material is filled between the front edge of the frame and the edge of the rear side of the top plate main body, and the silicone caulking material is dried to dry the top plate main body and the frame body. Is glued. Furthermore, since the silicone-based caulking material has elasticity even after being dried, in order to reinforce the adhesive state by the silicone-based caulking material and prevent the frame body from wobbling, it is in contact with the lower surface of the rear side of the top plate. A member is provided.

  According to this, a frame body such as a conventional front frame material or side frame material is not connected to the front side portion and the left and right side portions mainly of the top plate, and the original refreshing feeling of glass can be obtained well. Further, since the vent and the hood are formed with a single frame, the number of parts can be reduced and the cost can be reduced.

However, a gap of a predetermined size (about 3 mm) for filling the silicone-based caulking material must be provided between the front edge of the frame and the edge of the rear side of the top plate. In the filling operation of the silicone-based caulking material, it is necessary to use a positioning jig in order to maintain this gap, which not only increases the cost but also reduces the work efficiency. Moreover, since it takes a very long time (about 24 hours) until the silicone-based caulking material is dried and sufficient adhesion is obtained, the positioning jig cannot be removed until the silicone-based caulking material is dried. The yield is extremely bad. In order to shorten the drying time of the silicone caulking material and obtain high adhesive strength, it is conceivable to increase the viscosity of the silicone caulking material, but the edge of the front edge of the frame and the rear edge of the top plate The silicone caulking material is difficult to be filled in the gap provided between the two, and there is a possibility that an unfilled portion is generated. It is also possible to reduce the viscosity of the silicone caulking material so that the silicone caulking material can sufficiently penetrate into the gap between the front edge of the frame and the edge of the rear side of the top plate. However, the drying time of the silicone-based caulking material becomes longer and the working efficiency is poor. In addition, when a coking material having a low viscosity is used, the caulking material may flow out from the filling portion to the exterior portion mainly composed of the top plate, and it is necessary to remove the caulking material flowing out, so that the work efficiency is remarkably lowered. .

Further, when the lower surface of the cover portion of the frame body and the upper surface of the rear side portion of the top plate main body are bonded with the heat resistant adhesive tape, the contact portion provided on the frame body is used as the rear edge of the top plate main body. Since the positioning can be easily performed only by abutting, the top plate main body and the frame can be accurately bonded without using a positioning jig or the like. In addition, since the lower surface of the cover part, which is the bonding portion between the top plate main body and the frame body, and the upper surface of the rear side portion of the top plate main body are in close contact with each other via a heat-resistant adhesive tape, the top plate main body and the frame It is possible to surely prevent the spilled broth from entering the body, and to the functional parts (for example, an operating mechanism such as a cock or an electrical component such as a sparker) housed in the stove body. Since adhesion of boiled soup or the like can be prevented, the durability of the functional parts is not impaired, and it is advantageous in terms of hygiene.

  Moreover, in this invention, it is preferable that the said heat resistant adhesive tape is provided over the full length of the cover part of the said frame, and is provided inside the predetermined dimension from the front end of the cover part. Thereby, it is possible to prevent the heat resistant adhesive tape from being exposed from the front end of the cover portion, and it is possible to obtain a good appearance by preventing the heat resistant adhesive tape from being seen from the front.

  FIG. 1 shows a state where a drop-in stove 2 is incorporated in a countertop 1 of a system kitchen. As shown in FIG. 2, the stove 2 includes a box-shaped stove body 3 having an upper surface as an open surface. An outer bending flange 4 is formed on the upper edge of the stove body 3, and the outer bending flange 4 is placed at the opening edge of the stove opening 5 in a state where the stove body 3 is dropped into the stove opening 5 opened in the countertop 1. The stove body 3 is suspended from the countertop 1 by being hooked. The top plate 6 covers the stove body 3 over the outer bending flange 4 from above. A packing 7 is attached to the peripheral portion of the outer bending flange 4, and the outer bending flange 4 is seated on the counter top 1 via the packing 7 for preventing intrusion of boiled juice or the like due to spilling.

  The top plate 6 is a glass top plate composed of a top plate main body 8 made of heat-resistant glass such as ceramic glass and a frame body 9 provided along the rear side portion of the top plate main body 8.

  As shown in FIG. 1, the top plate main body 8 is provided with a pair of left and right burner openings facing the pair of left and right burners 10 and 10 as heat sources arranged in the stove body 3. On the top, a pair of left and right virtues 11 and 11 are placed so as to surround each burner opening. Each of the burners 10 and 10 is constituted by an internal flame type burner having a flame hole that opens inward. In addition, a pair of left and right operation knobs 12 and 12 for the burners 10 and 10 are arranged on the top plate main body 8 so as to be positioned at the front center portion.

  Here, the front side portion and the left and right side portions of the top plate main body 8 are frameless portions to which the frame body is not connected, and the original refreshing feeling of glass can be obtained satisfactorily. In addition, the sides connecting the frames need to be formed in a straight line, but by forming the front side portion and the left and right side portions of the top plate main body 8 into frameless portions, these sides are formed in a curved shape. It becomes possible to increase the degree of freedom in designing the shape of the glass top plate 6.

  As shown in FIG. 2, a packing 13 is attached to the lower surface of the top plate main body 8 by bonding or the like from the front side portion to the left and right side portions. Then, the front side portion and the left and right side portions of the top plate main body 8 are seated on the counter top 1 via the packing 13 outside the outer bending flange 4 of the stove body 3. Alternatively, the front side portion and the left and right side portions of the top plate main body 8 may be seated on the packing 7 attached to the outer bending flange 4 on the upper edge of the stove body 3 without attaching the packing 13.

  The frame body 9 is made of an extruded molding material of metal, for example, aluminum, and as shown in FIG. 2, a contact portion 14 that protrudes downward and abuts against a rear edge of the top plate main body 8 and a contact portion. A flat plate portion 15 extending substantially horizontally rearward from the portion 14, a hood portion 16 extending obliquely rearward and upward from the contact portion 14, and extending forward from the contact portion 14 to cover the upper surface of the rear side portion of the top plate main body 8. The cover part 17 is integrally formed by extrusion molding. In addition, the boundary portion between the cover portion 17 and the hood portion 16 including the upper position of the contact portion 14 is provided with a thick portion 18 that is thicker than the other portions in order to obtain sufficient bending strength. The cover portion 17 and the hood portion 16 are formed in a smoothly continuous shape via the thick portion 18.

  At the rear edge of the flat plate portion 15, a downward bent portion 19 is formed which is seated on the countertop 1 behind the outer bent flange 4 at the upper end of the rear wall portion of the stove body 3. Further, the flat plate portion 15 is provided with a vent 20 communicating with the inside of the stove main body 3 by post-processing after the extrusion molding, and the burners 10 and 10 are combusted in the stove main body 3 through the vent 20. Supply air is supplied. The vent 20 is covered with the hood portion 16 from the front to the top. Therefore, the vent 20 is hidden behind the hood portion 16 when viewed from the front, and the vent 20 can be seen from the front and does not impair the appearance. Further, the hood 16 prevents foreign matter such as dust from falling into the stove body 3 from the vent 20.

  The frame body 9 is firmly bonded and fixed through the heat-resistant adhesive tape 21 along the entire length of the rear side portion of the top plate main body 8. The heat resistant adhesive tape 21 bonds the lower surface of the cover portion 17 of the frame body 9 to the upper surface of the rear side portion of the top plate main body 8. At this time, the heat-resistant adhesive tape 21 is provided on the inner side from the front end of the cover portion 17 with a predetermined dimension (about 1 mm). The adhesive tape 21 employed in the present embodiment has an acrylic adhesive as a base material and an acrylic adhesive layer provided on both sides thereof, and has a heat resistance of about 200 ° C.

  When attaching the frame body 9 to the top plate main body 8, first, the peeling tape on one side of the heat-resistant adhesive tape 21 is peeled off and the adhesive surface exposed on one side is attached to the lower surface of the cover portion 17 of the frame body 9. Fix it. Next, the release tape on the other side of the heat-resistant adhesive tape 21 attached to the cover portion 17 is peeled off, and the upper surface of the rear side portion of the top plate main body 8 is attached to the exposed adhesive surface. At this time, the rear end edge of the top plate main body 8 is abutted against the side surface of the abutting portion 14 of the frame body 9 so that the top plate main body 8 and the frame body 9 can be quickly moved in a reliably positioned state. Can be glued.

  Further, even immediately after bonding with the heat-resistant adhesive tape 21, the bonding state between the top plate main body 8 and the frame body 9 is strong, and in the bonding position between the top plate main body 8 and the frame body 9, Since the high bending strength is ensured by the thick portion 18, inadvertent peeling of the heat-resistant adhesive tape 21 accompanying bending deformation at the boundary between the cover portion 17 and the hood portion 16 is prevented.

  Thus, by adopting the heat-resistant adhesive tape 21, there is no long waiting time until the silicone caulking agent dries as in the case of filling an adhesive made of a conventional silicone caulking agent, and In addition, it is not necessary to maintain the positioning state of the frame body 9 with respect to the top plate main body 8 so that the frame body 9 does not move carelessly until the silicon dries and a sufficient adhesive force is obtained. Installation can be performed quickly. Moreover, there is no need to provide a gap between the top plate main body 8 and the frame body 9 in order to fill the caulking agent as in the conventional case, and the top plate main body 8 is provided on the side surface of the convex contact portion 14 of the frame body 9. Since the positioning can be performed by just abutting the rear end edge, it is possible to reliably prevent the frame 9 from being displaced with respect to the top plate main body 8. Further, the frame 9 can be fixed to the top plate main body 8 without a gap by abutting the rear end edge of the top plate main body 8 against the side surface of the convex contact portion 14 of the frame 9. Intrusion of boiled juice or the like between the main body 8 and the frame body 9 can be reliably prevented. Moreover, by providing the heat resistant adhesive tape 21 inside the front end of the cover part 17, it can prevent that the heat resistant adhesive tape 21 is exposed from the front end of the cover part 17, and the heat resistant adhesive tape 21 is from the front. A good appearance can be obtained by making it invisible.
