Description

  The present invention relates to a glass top plate for a drop-in type stove in which a stove body is disposed so as to drop into a stove opening established on 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 countertop, the stove body has been hermetically sealed. In this state, sufficient combustion air is supplied to the burner in the stove body. become unable. Therefore, in the glass top plate, a vent is formed in the hanging wall portion seated on the counter top at the rear edge of the rear frame member so that combustion air can be supplied from the vent into the stove body.

  However, the height of the drooping wall part of the rear frame material cannot be increased to the left because of design restrictions, and the opening area of the vent opening in the drooping wall part cannot be secured as wide as the left side. It was difficult to supply sufficient air.

  Therefore, the applicant of the present application previously arranged a rear frame material as a glass top plate for a drop-in stove according to Japanese Patent Application No. 2003-22583, and separated the left and right side frame materials. A partition frame material is disposed along the rear side of the top plate between the partition frame material and the rear frame material to define a vent hole communicating with the inside of the stove body. A material in which a hood portion extending rearward and upward is integrally formed so as to cover the vent from the front of the vent on the material is proposed. 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 boiled spilled juice from falling into the vent.

However, in the glass top plate of the prior application, 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 portions along the left and right side portions of the top plate main body. There are five frame members, that is, a side frame member, a rear frame member, and a partition frame member. This increases the number of parts, requiring time for assembly, and increases the 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.
JP-A-11-22981 (0026 to 0028, FIGS. 1 to 3)

  In view of the above, the present invention provides a low-cost glass top plate for a drop-in type stove that has a vent and a hood portion that covers the vent and that can also provide a natural refreshing feeling. That is the issue.

In order to solve the above-mentioned problem, the present invention is a glass top plate for a drop-in type stove that is arranged so as to drop into a stove opening established on the counter top of the stove body.
It is composed of a glass top plate main body and a frame that is provided along only the rear side of the periphery of the top plate main body. A front edge portion facing the edge of the rear side portion with a gap in the front-rear direction, a flat plate portion extending substantially horizontally rearward from the front edge portion, a hood portion extending obliquely rearward and upward from the front edge portion, and the front A vent that is formed of a metal extrusion molding material that has a cover portion that projects forward from the edge portion and covers the upper surface of the rear side of the top plate, and communicates with the inside of the stove body by post-processing after extrusion molding to the flat plate portion. Was established, and the frame body was joined to the top plate main body by silicone caulking material filling the gap between the front edge of the frame body and the edge of the rear side of the top plate main body. A receiving member separate from the frame that contacts the lower surface of the rear side portion is provided, and the receiving member is cantilevered on the lower surface of the flat plate portion. Characterized in that it is attached.

  According to the above configuration, a frame body such as a conventional front frame material and 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 satisfactorily. Moreover, a vent hole can be opened in a wide area in the flat plate portion of the frame body along the rear side portion of the top plate main body, so that combustion air can be sufficiently supplied into the stove body. Furthermore, when viewed from the front, the vent is hidden behind the hood, and the caulking material filled between the front edge of the frame and the edge of the rear side of the top plate is covered by the cover, Appearance is improved. Further, the hood portion prevents the boiled juice from dropping into the vent. In addition, since the vent and the hood are formed from a single frame, the number of parts can be reduced and the cost can be reduced.

  By the way, the silicone caulking material is used to bond the top plate main body and the frame to ensure heat resistance. However, since the silicone caulking material is highly elastic, the frame is wobbled during transport of the top plate. It is easy, and the outer frame may sometimes wobble excessively and the caulking material may be broken. However, in the present invention, the rear side portion of the top plate main body is sandwiched from above and below by the cover portion and the receiving member, so that the wobbling of the frame body is suppressed, and the caulking material is sunk by the excessive wobbling of the frame body during the transport of the top plate. There is no problem of running out.

  It is also conceivable that the receiving member is integrally formed so as to extend from the front edge of the frame body without making the receiving member separate from the frame body. Here, the glass plate which is the main body of the top plate has a property that it is strong against an impact from the upper surface side but weak against an impact from the lower surface side. In the state where the top plate is installed on the countertop, impact force does not act on the bottom surface of the top plate main body, but when an external force is applied to the frame body during transport of the top plate, or downward When an external force acts on the cover member and a moment that pushes up the receiving member with the cover portion as a fulcrum is applied, an impact force is applied from the receiving member to the lower surface of the top plate main body. When the receiving member is integrally formed at the front edge of the frame body as described above, the rigidity of the receiving member increases, so that when an external force is applied to the frame body, the receiving member is received on the lower surface of the top plate main body (glass plate). A relatively strong impact force acts from the member, and there is a possibility that the top plate is mainly cracked. On the other hand, in the present invention, since the receiving member separate from the frame is attached to the flat plate portion in a cantilevered state, the receiving member is easily inclined downward, and even if an external force acts on the frame, the receiving member The impact force acting on the lower surface of the top plate main body is mitigated by the inclination of the member, and the top plate main body is not cracked.

  By the way, there is a possibility that the caulking material filling the gap between the front edge portion of the frame body and the edge of the rear side portion of the top plate main body swells on the lower surface side, and the receiving member interferes there. In order to prevent this interference, a groove may be formed on the upper surface of the receiving member so as to be positioned at a portion facing the gap between the front edge portion of the frame body and the edge of the rear side portion of the top plate main body. desirable. And if a groove | channel is formed, a groove | channel becomes a weakened part and a receiving member will become easy to bend, and the impact force which acts on the lower surface of a top plate main body will be relieved also by this bending.

  Further, if the receiving member is made of resin, the contact of the receiving member with the lower surface of the top plate main body is softened, and cracking of the top plate main body is further reliably prevented.

  FIG. 1 shows a state in which a drop-in stove is incorporated in the countertop 1 of the system kitchen. As shown in FIG. 2, the stove includes a box-shaped stove body 2 having an upper surface as an open surface. An outer bending flange 2 a is formed on the upper edge of the stove body 2, and the outer bending flange 2 a is placed at the opening edge of the stove opening 1 a in a state where the stove body 2 is dropped into the stove opening 1 a opened in the countertop 1. The stove body 2 is suspended from the countertop 1 by being hooked. And the top plate 3 covers the stove body 2 over the outer bending flange 2a from above. A packing 2b is attached to the peripheral edge of the outer bending flange 2a, and the outer bending flange 2a is seated on the counter top 1 via the packing 2b.

  The top plate 3 is a glass top plate composed of a top plate main body 4 made of heat-resistant glass such as ceramic glass and a frame body 5 provided along the rear side portion of the top plate main body 4. The top plate main body 4 is provided with a pair of left and right burner openings facing the pair of left and right burners 6 and 6 that are heat sources arranged in the stove body 2, and each burner opening is provided on the top plate main body 4. A pair of left and right virtues 7 and 7 are placed so as to surround. Each burner 6 is composed of an internal flame type burner having a flame hole that opens inward. A pair of left and right operation knobs 8 and 8 for each burner 6 are arranged on the top plate main body 4 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 4 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 4 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 3.

  A packing 41 is attached to the lower surface of the top plate main body 4 from the front side portion to the left and right side portions by adhesion or the like. Then, the front side portion and the left and right side portions of the top plate main body 4 are seated on the counter top 1 via the packing 41 on the outside of the outer bending flange 2 a of the stove body 2. The packings 41 on the left and right side portions of the top plate main body 4 extend over the frame body 5. Note that the front side portion and the left and right side portions of the top plate main body 4 may be seated on the packing 2b attached to the outer bending flange 2a on the upper edge of the stove body 2 without attaching the packing 41.

  The frame body 5 is made of an extruded molding material of metal, for example, aluminum, and has a front edge portion 51 facing the edge of the rear side portion of the top plate main body 4 with a gap in the front-rear direction, and a front edge A flat plate portion 52 extending substantially horizontally rearward from the portion 51, a hood portion 53 extending obliquely rearward and upward from the front edge portion 51, and projecting forward from the front edge portion 51 to cover the upper surface of the rear side portion of the top plate main body 4 The cover part 54 is integrally formed by extrusion molding. At the rear edge of the flat plate portion 52, a downward bent portion 52 a that is seated on the countertop 1 is formed at the rear side of the outer bending flange 2 a at the upper edge of the rear wall portion of the stove body 2. The flat plate portion 52 is provided with a vent 55 communicating with the inside of the stove main body 2 by post-processing after extrusion. Thus, the combustion air for the burner 6 is supplied into the stove body 2 through the vent 55. The vent 55 is covered by the hood portion 53 from the front to the top. Therefore, the vent 55 is hidden behind the hood portion 53 when viewed from the front, and the vent 55 can be seen from the front and does not impair the appearance. Furthermore, the food part 53 prevents foreign matter such as boiled juice from falling into the stove body 3 from the vent hole 55.

  A gap between the front edge 51 of the frame 5 and the end surface of the rear side of the top plate main body 4 is filled with a silicone-based caulking material 56 such as silicone rubber. The frame body 5 is coupled to the top plate main body 4. Here, when the caulking material 56 appears on the appearance, the appearance is impaired, but the filling portion of the caulking material 56 is covered from above by the cover portion 54, and the appearance is not impaired. Further, a small protrusion 51a is formed on the lower surface of the front edge portion 51 of the frame body 5 so as to protrude slightly downward from the lower surface of the flat plate portion 52, so that the caulking material 56 does not protrude to the flat plate portion 52 side. This is prevented by the protrusion 51a.

  Further, the flat plate portion 52 is formed with an engagement hole 57 that engages with a positioning bolt 9 erected on the outer bending flange 2 a on the upper edge of the rear wall portion of the stove body 2. A washer 9 a sandwiched between the outer bending flange 2 a and the flat plate portion 52 is extrapolated to the positioning bolt 9. The nut 9 b is screwed into the positioning bolt 9 from above the flat plate portion 52 so that the top plate 3 can be fixed in a state of being positioned with respect to the stove body 2.

  By the way, although the silicone-based caulking material 56 is excellent in heat resistance, since it is rich in elasticity, the frame body 5 is wobbled when the top plate is conveyed as it is. Therefore, in the present embodiment, two receiving members 10 are provided on the left and right sides, separate from the frame 5 in contact with the lower surface of the rear side portion of the top plate main body 4, and each receiving member 10 is screwed to the lower surface of the flat plate portion 52. It is attached in a cantilever state. The receiving member 10 is made of resin, and a filling portion of the caulking material 56 on the upper surface of the receiving member 10 (a gap between the edge of the rear side portion of the top plate main body 4 and the front edge portion 51 of the frame body 5) and the above A groove 10b for avoiding interference with the caulking material 56 and the small protrusion 51a is formed in a portion facing the small protrusion 51a.

  When the receiving member 10 is provided in this manner, the frame 5 is engaged with the rear side portion of the top plate main body 4 so as to be sandwiched between the cover portion 54 and the receiving member 10 from above and below. As a result, the wobbling of the frame body 5 is suppressed, and there is no problem that the caulking material 56 is cut off due to excessive wobbling of the frame body 5 during transport of the top plate.

  A moment that pushes up the receiving member 10 with the cover 52 serving as a fulcrum when an upward external force acts on the frame 5 during transport of the top plate or when a downward external force acts on the frame 5. When works, impact force may be applied from the receiving member to the lower surface of the top plate. Here, when the receiving member 10 is integrally formed with the frame body 5 so as to extend from the front edge portion 51 of the frame body 5, the rigidity of the receiving member 10 is increased, and the receiving member is formed on the lower surface of the top plate main body 4. There is a possibility that a relatively strong impact force will act from 10 and the top plate main body 4 will be cracked.

  On the other hand, since the receiving member 10 of this embodiment is a separate body from the frame 5 and is attached to the flat plate portion 52 in a cantilever state, the supporting rigidity of the receiving member 10 is relatively low, and the receiving member 10 easily tilts downward, and the groove 10b formed in the receiving member 10 becomes a weakened portion, and the receiving member 10 is easily bent. Therefore, even if an external force is applied to the frame 5, the impact force from the receiving member 10 acting on the lower surface of the top plate main body 4 is alleviated by the inclination and bending of the receiving member 10, and cracking of the top plate main body 4 is effective. To be prevented. Further, in the present embodiment, since the receiving member 10 is made of resin, the contact of the receiving member 10 with the lower surface of the top plate main body 4 is softened, and cracking of the top plate main body 4 is more reliably prevented. It should be noted that the screw 10a should not be tightened as strongly as the left so that the receiving member 10 can be easily tilted.

  As described above, the embodiment in which the ventilation hole 55 for taking in combustion air is formed in the frame body 5 has been described. However, the drop-in hob with a grill has a ventilation hole for exhausting exhaust from the grill. The present invention can be similarly applied to a case where the glass top plate is provided.
