The present invention relates to a glass top plate for a drop recognition furnace, which is arranged so as to be inserted into a furnace opening formed in a countertop.

Conventionally, in this kind of drop recognition furnace, it is known to use the glass top plate made from the glass of the main part (top main body) which is good in external appearance and cleaning property as a top plate (for example, refer patent document 1). The glass top plate is composed of a glass main body and a frame surrounding the periphery of the top main body, and the outer frame is formed on the left and right sides of the front frame member along the front side of the main body and the left and right sides of the top main body. It is composed by connecting the frame material along the rear side part of the side frame material and the upper plate body in a frame shape. Moreover, in a drop recognition furnace, in order to prevent the heat in a furnace main body from hitting a countertop, the sealing of the furnace main body is improved, and in that state, it becomes impossible to supply sufficient combustion air to the burner in the furnace main body. Therefore, in the glass plate, an air vent is formed in the drooping wall portion seated on the counter top of the rear edge of the frame member, so that the combustion air can be supplied from the vent to the furnace body.

However, since the height of the drooping wall portion of the hull material cannot be made very high due to design constraints, and the opening area of the vent provided in the drooping wall portion cannot be secured too widely, it is difficult to supply sufficient combustion air.

Thus, the applicant of the present application is a glass top plate for a drop recognition furnace according to Japanese Patent Application No. 2003-22583, which is arranged by dropping the frame material to the rear of the upper plate main body, and placing the partition frame material along the rear side part of the upper plate main body between the left and right side frame materials. It arrange | positioned, and it partitions between the partition material and the frame material, and forms the ventilation hole which connects in the furnace body continuously, and also proposes that integrally formed the hood part extended rearward by covering the ventilation hole in front of the ventilation hole in the partition material, have. According to this, the opening area of the air vent can be widened to sufficiently supply the combustion air into the main body, and since the air vent is hidden behind the hood when viewed from the front, foreign matter such as boiled broth is not damaged. Falling to the vent is also prevented by the hood portion.

However, in the glass top plate of the source, the outer frame surrounding the top plate made of glass includes five front frame members along the front side part of the top plate and left and right side frame members along the left and right side portions of the top plate body, frame material and partition frame material. It is made of a frame member, the number of parts is increased, it takes time to assemble, there is an inconvenience that the cost is high. Moreover, since the whole periphery of the upper plate main body is surrounded by an outer frame, the neatness of glass originality may be impaired.

[Patent Document 1] Japanese Patent Application Laid-Open No. 11-22981 (0026 to 0028, Figs. 1 to 3)

In view of the above, it is an object of this invention to provide the glass top plate for low cost drop recognition furnaces which has a vent and the hood part which covers this, and also obtains the intrinsic neatness of glass.

MEANS TO SOLVE THE PROBLEM In order to solve the said subject, this invention is the glass top plate for drop recognition furnaces arrange | positioned so that a furnace main body may be inserted in the furnace opening formed in the countertop,

It consists of a glass main body and a frame body separate from the top body, which is formed along only the rear side part in the periphery of the top body, and the frame body has a front edge facing each other with a gap in the front and rear direction at the end edge of the rear side part of the top body. A cover which covers the upper surface of the rear side part of the main body of the main body, a flat plate portion extending substantially horizontally from the front edge portion to the rear, a hood portion extending obliquely upward from the front edge portion, and protruding forward from the front edge portion. It is formed by an extruded metal material having a part, and a vent is formed in the flat plate body through the post-processing after extrusion molding, and is filled in the gap between the front edge of the frame and the end edge of the rear side of the upper plate body. The framework is joined to the upper plate main body by a silicone-based caulking material, and the rear side of the upper main body A support member is provided separately from the frame contacting the lower surface of the portion, and the support member is attached to the lower surface of the flat plate in a cantilevered state.

According to the said structure, the former frame material and the frame body of a side frame member are not connected to the front side part and the left side part part of an upper plate main body, and the inherent neatness of glass can be obtained favorably. Moreover, a vent can be formed in a large area in the flat part of the frame along the rear side part of the upper plate main body, and therefore, the combustion air can be sufficiently supplied into the furnace main body. In addition, the vent is hidden behind the hood as viewed from the front, and the caulking material to be filled between the front edge of the frame and the end edge of the rear side of the upper plate body is covered by the cover to provide good appearance. The hood part also prevents falling of boiled broth and the like into the vent. In addition, since the air vent and the hood portion are formed in a single frame body, the number of parts can be reduced and the cost can be reduced.

By the way, the use of the silicone-based caulking material for the coupling of the upper body and the frame is to ensure heat resistance, but the silicone-based caulking material is excellent in elasticity, the frame is easy to shake during conveyance of the top plate, sometimes the outer frame is excessively shaken to break the caulking material There is a possibility of falling. However, in the present invention, since the rear side portion of the upper plate main body is sandwiched between the upper and lower sides by the cover portion and the supporting member, the shaking of the frame is suppressed, and the inconvenience of breaking the caulking material due to excessive shaking of the frame during conveying the upper plate does not occur. .

In addition, it is also conceivable to integrally shape the supporting member so that the supporting member extends from the front edge thereof without the supporting member being separate from the frame. Here, the glass plate used as the upper plate main body has a property of being strong against the impact on the upper surface side but weak to the impact on the lower surface side. In the state where the upper plate is installed on the countertop, the impact force does not act on the lower surface of the upper plate main body, but when the upper plate is exerted by the external force on the frame during the conveyance of the upper plate or the external force acts downward on the frame, When the moment of pushing up the supporting member acts, the impact force acts on the lower surface of the upper plate main body from the supporting member. As described above, when the supporting member is integrally formed and formed on the front edge of the frame, the rigidity of the supporting member is increased. Therefore, when an external force acts on the frame, a relatively strong impact force is applied from the supporting member to the lower surface of the upper plate main body (glass plate). This action may cause cracking of the main plate body. On the contrary, in the present invention, since the supporting member is attached to the flat plate in a cantilever state, the supporting member tends to be tilted downward, and even if an external force is applied to the frame, the upper plate is subject to tilting of the supporting member. The impact force acting on the lower surface of the upper surface is alleviated, and cracking of the upper plate main body does not occur.

By the way, the caulking material which fills in the space | interval between the front edge part of a frame body and the edge of the edge part of the back side part of an upper plate main body will accumulate on the lower surface side, and a support member may interfere here. In order to prevent this interference, it is preferable to form a groove on the upper surface of the supporting member at a portion opposing the gap between the front edge of the frame and the end edge of the rear edge of the upper plate body. When the groove is formed, the groove becomes a weakened portion and the supporting member tends to bend, and the bending force also reduces the impact force acting on the lower surface of the upper plate main body.

Moreover, when the support member is made of resin, the touch of the support member to the lower surface of the upper plate main body is softened, and the cracking of the upper plate main body is more reliably prevented.

(The best form to carry out invention)

Fig. 1 shows a state in which a drop recognition furnace is assembled to the counter top 1 of the system kitchen. As shown in FIG. 2, the furnace body includes a box-shaped furnace body 2 having an upper surface as an open surface. The outer bend flange 2a is formed in the upper edge of the furnace main body 2, and the outer bend flange 2a is inserted in the furnace opening 1a formed in the furnace top 2 formed in the countertop 1. ) Is hooked to the edge of the opening of the furnace opening 1a, and the furnace body 2 is held on the counter top 1. The top plate 3 covers the furnace main body 2 from above over the outer bend flange 2a. Moreover, the packing 2b is attached to the peripheral part of the outer bending flange 2a, and the outer bending flange 2a is seated on the counter top 1 via the packing 2b.

The upper plate 3 is a glass upper plate composed of an upper plate main body 4 made of heat-resistant glass such as ceramic glass and a frame 5 formed along the rear side portion of the upper plate main body 4. The upper plate main body 4 is formed with a pair of left and right burner openings in which a pair of left and right burners 6 and 6 as heat sources disposed in the main body 2 are formed, and openings for each burner are placed on the upper plate main body 4. It is surrounded by a pair of left and right trivets (7,7). Each burner 6 is comprised with a flameproof burner which has a flame hole which opens inwardly. Moreover, it is located in the front center part on the upper plate main body 4, and the left and right pair of operation handles 8 and 8 for each burner 6 are arrange | positioned.

Here, the front side part and the left and right side parts of the upper plate main body 4 are frameless parts to which a frame is not connected, and the neatness of glass originality can be obtained favorably. In addition, the sides connecting the frame body must be formed in a straight line, but by forming the front side portion and the left and right side edge portions of the upper plate main body 4 as a frameless portion, these sides can be formed in a curved shape, Freedom of design regarding the shape of the glass top plate 3 also becomes high.

The packing 41 is attached to the lower surface of the upper plate main body 4 from the front edge portion to the left and right side edge portions by adhesion or the like. And the front side part and the left and right side part of the upper plate main body 4 are seated on the counter top 1 via the packing 41 in the outer side of the outer bending flange 2a of the furnace main body 2. . The packing 41 at the left and right side portions of the upper plate main body 4 extends over the frame 5. Further, the front side part and the left and right side parts of the upper plate main body 4 are seated on the packing 2b attached to the outer bend flange 2a of the upper edge of the furnace body 2 without attaching the packing 41. You may do so.

The frame 5 is made of an extruded molding material made of metal, for example, aluminum, and has a front edge 51 facing the end edge of the rear side part of the upper plate body 4 with a gap in the front and rear direction, and the front side. A flat portion 52 extending substantially horizontally from the edge portion 51 to the rear, a hood portion 53 extending obliquely upward from the front edge portion 51, and protruding forward from the front edge portion 51. The cover part 54 which covers the upper surface of the rear side part of the upper plate main body 4 is integrally formed by extrusion molding. At the rear edge of the flat plate portion 52, there is formed a bent portion 52a downwardly seated on the counter top 1 from the rear side than the outer bend flange 2a of the rear wall portion upper edge of the furnace main body 2. In addition, the flat plate portion 52 is provided with a vent hole 55 connected in the furnace main body 2 by post-processing after extrusion molding. In this way, the combustion air of the burner 6 is supplied into the furnace main body 2 via the vent 55. In addition, the air vent 55 is covered by the hood portion 53 from the front to the top thereof. For this reason, the air vent 55 is hidden behind the hood part 53 when seen from the front, and the air vent 55 does not impair the external appearance when seen from the front. In addition, the hood 53 prevents foreign substances such as boiled broth from falling into the furnace main body 3 from the air vent 55.

The gap between the front edge 51 of the mold 5 and the end face of the rear side of the upper plate main body 4 is filled with a silicone-based caulking material 56 such as silicone rubber. The frame 5 is coupled to the upper plate main body 4 by the adhesive force. Here, the appearance of the caulking material 56 damages the appearance, but the filling portion of the caulking material 56 is covered by the cover portion 54 from above, and does not damage the appearance. Moreover, the small protrusion 51a which protrudes slightly below the lower surface of the flat plate part 52 is formed in the lower surface of the front edge part 51 of the frame 5, and the caulking material 56 is the flat plate part 52. Pushing out to the side is prevented by the small protrusion 51a.

In addition, the flat plate portion 52 is provided with an engagement hole 57 that engages with the positioning bolt 9 placed in the outer bending flange 2a at the upper edge of the rear wall portion of the furnace body 2. The washer 9a fitted between the outer bending flange 2a and the flat plate portion 52 is externally fitted to the positioning bolt 9. Then, the nut 9b is screwed into the positioning bolt 9 from above the flat plate portion 52, so that the upper plate 3 can be fixed in a state in which it is positioned with respect to the furnace main body 2.

By the way, although the silicone type caulking material 56 is excellent in heat resistance, since it is rich in elasticity, the frame 5 will shake in the state of top plate conveyance in that state. Thus, in the present embodiment, two support members 10 are formed on the left and right sides of the plate body 52, which are separate from the frame body 5 in contact with the lower surface of the rear side of the upper plate main body 4. To the cantilevered state with screws 10a. The supporting member 10 is made of resin, and the filling point of the caulking material 56 on the upper surface of the supporting member 10 (the end edge of the rear side part of the upper plate main body 4 and the front edge 51 of the frame 5). In the gap between the < RTI ID = 0.0 >) < / RTI > and the portion facing the small protrusion 51a, a groove 10b is formed to avoid interference with the caulking material 56 and the small protrusion 51a.

When the supporting member 10 is formed in this way, the frame body 5 is fitted to the rear side of the upper plate main body 4 by being fitted between the upper and lower sides by the cover portion 54 and the supporting member 10. As a result, the shake of the frame 5 is suppressed, and the inconvenience that the caulking material 56 falls off by excessive shake of the frame 5 during top plate conveyance does not arise.

In addition, the moment when the external force acts upward on the frame 5 during the upper plate conveyance, or the external force acts downward on the frame 5 to push up the supporting member 10 with the cover 54 as a point. When is applied, the impact force may act on the lower surface of the upper plate main body from the supporting member. Here, when the support member 10 is integrally molded to the frame 5 so as to extend from the front edge portion 51 of the frame 5, the rigidity of the support member 10 becomes high, and the lower surface of the upper plate main body 4 There is a possibility that a relatively strong impact force acts on the supporting member 10 to cause cracking of the upper plate main body 4.

On the other hand, since the supporting member 10 of the present embodiment is attached to the flat plate 52 in a cantilever state separately from the frame 5, the supporting rigidity of the supporting member 10 is relatively low, and the supporting member 10 is relatively low. It becomes easy to incline 10, and the groove | channel 10b formed in the support member 10 becomes a weakening part, and the support member 10 becomes easy to bend. For this reason, even if an external force acts on the frame 5, the impact force from the supporting member 10 acting on the lower surface of the upper plate main body 4 is alleviated by the inclination and bending of the supporting member 10, and the upper plate main body 4 The cracking of the is effectively prevented. In addition, in this embodiment, since the support member 10 is made of resin, the touch of the support member 10 with respect to the lower surface of the upper plate main body 4 becomes soft, and the crack of the upper plate main body 4 is prevented more reliably. In addition, the screw 10a is preferably not fastened so much that the support member 10 is easily inclined.

As mentioned above, although embodiment which provided the vent 55 for introducing the combustion air into the frame 5 was described, in the drop recognition furnace with a grill, the vent for exhausting the exhaust from a grill is attached to the glass plate. Also when forming, this invention can be applied similarly.

ADVANTAGE OF THE INVENTION According to this invention, the glass top plate for low cost drop recognition furnaces can be provided which has the ventilation hole which connects in the furnace main body and the hood part which covers this, and also obtains the intrinsic neatness of glass favorably.
