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 stove, in order to prevent the hot air in the stove body from reaching the countertop, the stove body has been improved in sealing performance, so that the combustion air is sufficiently supplied to the burner in the stove body. It becomes impossible to supply. 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 portion of the rear frame material cannot be so high due to design restrictions, and the opening area of the vent opening established in the drooping wall portion cannot be secured so large, so that the combustion air is not There is a risk that it will be difficult to supply it sufficiently. In particular, when the distance between the vent and the rear wall surface is narrow, there is a possibility that the amount of combustion air is insufficient.

  Next, an example of an embodiment of a glass top plate for a drop-in stove according to the present invention will be described with reference to FIGS. First, the glass top plate which is the 1st example of 1st Embodiment shown in FIG.1 and FIG.2 is demonstrated.

  FIG. 1 shows a state where a drop-in stove 2 is incorporated in a countertop 1 of a system kitchen. The stove 2 includes a glass top plate 3 placed on the surface of the countertop 1 and a box-shaped stove body 4 having an upper surface as an open surface as shown in FIG. A flange portion 4a projecting outward is formed on the upper edge of the stove body 4, and the flange portion 4a is opened to the stove opening 1a in a state where the stove body 4 is dropped into the stove opening 1a provided in the countertop 1. The stove body 4 is suspended from the counter top 1 by being hooked to the edge.

  Further, a packing 4b is attached to the outer peripheral edge of the flange portion 4a, and the flange portion 4a is placed on the counter top 1 through the packing 4b. The stove body 4 is covered with the glass top plate 3 from above. As described above, the stove body 4 has a structure with improved hermeticity so that internal hot air does not reach the countertop 1. Further, a packing 5 is provided between the back surface of the glass top plate 3 and the surface of the countertop 1 so as to surround the packing 4b. The packing 5 is fixed to the back surface of the glass top plate 3 with an adhesive or an adhesive tape.

  The glass top plate 3 includes a top plate main body 6 made of heat-resistant glass such as ceramic glass, a front frame body 7 provided along a front side portion of the top plate main body 6, and a rear side portion of the top plate main body 6. The rear frame body 8 is provided with the rear frame. The top plate main body 6 is provided with a pair of left and right burner openings to which a pair of left and right burners 9 disposed in the stove body 4 are attached. The top plate main body 6 is surrounded by each burner opening. A pair of left and right virtues 9a are placed. The burner 9 is a so-called shield-type burner in which the spilled broth or the like does not enter the stove main body 4 even when it is spilled during cooking.

  The front frame 7 and the rear frame 8 are made of an extruded material of metal, for example, aluminum. The front frame body 7 includes a first edge portion 7b having a first groove portion 7a into which a front side portion of the top plate main body 6 is inserted from the rear, and a first ventilation that protrudes forward from the first edge portion 7b and is open on the left and right sides. And a cylindrical front tube portion 7c provided with a mouth 11. This front cylinder part 7c has the inclination part 7d which inclines toward the front, and is formed so that it may become a substantially flat pentagon in side view. Moreover, the 2nd ventilation hole 12 formed in the left and right two places of the lower surface 7e of the front cylinder part 7c by the post-process after extrusion molding, and is connected in the stove main body 4 is provided. A pair of left and right operation knobs 9b for performing an ignition operation of each burner 9 and the like are attached to the inclined portion 7d of the front cylinder portion 7c.

  The rear frame 8 is formed integrally with the second edge 8b provided with the second concave groove 8a into which the rear side portion of the top plate main body 6 is inserted from the front, and protrudes rearward thereof. And a cylindrical rear cylinder portion 8c (rear ventilation portion) provided with a third vent 13 that is open on the left and right. The rear cylinder portion 8c has an inclined portion 8d that is largely chamfered forward, and the back surface is a flat portion 8e that rises vertically, and is formed to be substantially trapezoidal in a side view. Moreover, the 4th ventilation hole 14 formed in the left-right two places of the lower surface 8f of the rear cylinder part 8c by the post-process after extrusion molding, and connecting in the stove main body 4 is provided. In the first example, a rear ventilation passage is formed by the third ventilation hole 13 and the fourth ventilation hole 14.

  The glass top plate 3 of the first example is formed such that the total opening area of the two second vent holes 12 is larger than the total opening area of the left and right first vent holes 11. Similarly, the total opening area of the fourth vent holes 14 is formed to be larger than the total opening area of the third vent holes 13.

  The reason is as follows. Both the first vent hole 11 and the third vent hole 13 are provided on the side surfaces of the front frame body 7 and the rear frame body 8, and these frame bodies cannot be made too large for convenience or design. The opening area cannot be too large. On the other hand, the second vent hole 12 and the fourth vent hole 14 are not visible from the outside and are not subject to such restrictions, so that the opening area can be increased. Further, by taking the second vent hole 12 and the fourth vent hole 14 wider than the first vent hole 11 and the third vent hole 13, the ventilation capacity of the first vent hole 11 and the third vent hole 13 is maximized. This is because it can be saved.

  When connecting the top plate main body 6 and the front frame body 7, the first concave groove portion 7 a is filled with the adhesive 15 made of a silicone-based caulking agent, and the adhesive is applied to the end surface of the front side of the top plate main body 6. In this state, the front side portion of the top plate main body 6 is inserted into the first groove portion 7a. Thereby, the front side end surface of the top plate main body 6 is bonded to the first edge portion 7b. As with the front frame 7, the rear frame 8 is also filled with the adhesive 15 in the second concave groove 8a, and the rear end surface of the top plate main body 6 is inserted into the second concave groove 8a to be bonded.

  In the first example, mesh-shaped vent guards 16 and 17 are attached to the first vent 11 and the third vent 13. The vent guards 16 and 17 are provided to prevent insects, rats, cotton dust, dust, and the like from entering the stove body 4. The vent guards 16 and 17 may be formed of metal as in the case of the front and rear frames, or may be formed of synthetic resin.

  Since the glass top plate 3 of the first example has the above-described configuration, when the burner 9 is ignited and burned by the operation knob 9b, the air in the stove body 4 is used as the combustion air and the combustion is performed. Is called. When the air in the stove main body 4 is used in this way, the outside air passes through the second vent 12 opened toward the stove main body 4 and the first vent 11 provided on the left and right of the front cylinder portion 7c. Is supplied into the stove body 4. At the same time, outside air is supplied into the stove body 4 via the fourth vent hole 14 opened toward the stove body 4 and the third vent holes 13 provided on the left and right sides of the rear cylinder portion 8c.

  In the glass top plate 3 of the first example, since the opening area of the second ventilation hole 12 is formed larger than the opening area of the first ventilation hole 11, the air supplied from the first ventilation hole 11 is smoothly supplied. It can be supplied into the stove body 4. Similarly, the outside air can be smoothly supplied into the stove body 4 from the fourth vent hole 14 and the third vent hole 13. Thereby, for example, as shown in FIG. 1, even when the space between the glass top plate 3 and the rear wall surface W is small, the combustion air for the burner 9 can be sufficiently supplied into the stove body 4. . Furthermore, since the entry of pests and the like can be prevented by the vent guards 16 and 17 provided in the first and third vents 11 and 13, the pests and the like do not enter the stove body 4.

  A modification of the first example is shown in FIG. In this modified example, a fifth ventilation port 18 that communicates the inside and the outside of the rear frame 8 is provided in a flat portion 8 e formed on the rear surface of the rear frame 8. Further, the fourth vent 14 is formed with an opening area that is substantially the same as the opening areas of the third vent 13 and the fifth vent 18. In this modification, a rear ventilation passage is formed by the third ventilation port 13, the fourth ventilation port 14, and the fifth ventilation passage. The fifth vent 18 is also provided with a vent guard 19.

  Thus, by providing the rear frame 8 with the fifth vent 18 in addition to the third vent 13, more air can be guided into the stove body 4. Moreover, since the 5th ventilation port 18 exists in the position which cannot be seen by the user who uses the stove 2, much air can be guide | induced in the stove main body 4 with the external appearance design similar to the said 1st example.

  Next, a glass top plate 21 as a second example of the first embodiment will be described with reference to FIG. The glass top plate 21 of the second example is different from the first example in the rear frame 22 provided along the rear side portion of the top plate main body 6 made of heat-resistant glass. The rear frame 22 of the second example is made of an extruded material made of metal such as aluminum. 4 (a) and 4 (b), a second edge 22b provided with a second concave groove 22a into which the rear side of the top plate main body 6 is inserted from the front, and a second edge 22b. The upper plate 22c extends rearward from above, and the lower plate 22d extends rearward from below the second edge 22b. The upper plate 22c has a shape extending horizontally rearward from the second edge 22b and a rear portion extending vertically downward. The lower plate 22d is provided with a central plate 22e that protrudes upward from the central portion in a side view.

  Since the rear frame body 22 is formed of a metal extrusion molding material, the left and right end portions are opened to form the third ventilation holes 23. Further, the lower plate 22d is provided with a fourth vent hole 24 that passes through the front and back surfaces and opens toward the stove body 4. Further, a gap 25 is provided between the leading edge of the upper plate 22c and the leading edge of the lower plate 22d. In this second example, this interval 25 is the fifth vent.

  As shown in FIG. 4A, a reinforcing frame body 26 interposed between the inner surface of the upper plate 22c and the inner surface of the lower plate 22d is attached to the third vent hole 23. In the reinforcing frame 26, the outer shell 26a is formed of a rigid material, for example, a metal such as aluminum. The reinforcing frame 26 also serves as a vent guard, and a net 26b is provided inside the outer shell 26a. This net 26b prevents the entry of pests and the like into the interior. By attaching the reinforcing frame 26 to the rear frame 22, for example, even when a force is applied to the upper plate 22c, the upper frame 22c is deformed because it is interposed between the upper plate 22c and the lower plate 22d. Can be prevented. Thereby, since the change of the width | variety of the space | interval 25 is prevented, the ventilation capability of a 5th vent hole is ensured.

  Further, in the second example, the width of the interval 25 is set to a width (for example, about 3 mm) that is difficult for pests and the like to enter. The distance between the center plate 22e provided on the lower plate 22d and the upper plate 22c is also set to the same width. In the second example, when air is supplied into the stove body 4 from the interval 25 that is the fifth vent, the supplied air meanders by the center plate 22e. For this reason, even when dust or the like is present in the air, the dust or the like is removed by the center plate 22e. Note that the width of the interval 25 may be widened to provide a vent guard. Since other configurations are the same as those in the first example, the same reference numerals are given to the same configurations in the drawings, and detailed description thereof is omitted.

  Since the glass top plate 21 of the second example has the above-described configuration, when the burner 9 is ignited and burned by the operation knob 9b, the air in the stove body 4 is used as combustion air and burns. Is called. When the air in the stove body 4 is used in this way, the outside air passes through the second vent 12 opened toward the stove body 4 and the first vents 11 provided on the left and right sides of the front tube portion 7. Is supplied into the stove body 4. At the same time, outside air is supplied into the stove main body 4 through the fourth vent 24 and the third vent 23 opened toward the inside of the stove main body 4, and further through the fifth vent. In the glass top plate 21 of the second example, since the fourth vent 24 is formed larger than the opening area of the third vent 23, the air supplied from the third vent 23 and further from the fifth vent. Can be smoothly supplied into the stove body 4.

  Next, the glass top plate 31 which is the 3rd example of 1st Embodiment is demonstrated with reference to FIG. The glass top plate 31 of the third example is different from the first example in the shape of the rear frame and the shape of the top plate main body. The rear frame body 32 of the third example is formed of an extrusion molding material, and the rear cylinder part 34 is directed from the front of the second edge part 32b provided with the second concave groove part 32a toward the surface of the top plate main body 33. It has been extended. The rear cylinder portion 34 is formed to be an isosceles triangle in a side view, and the third vent holes 35 opened to the left and right are also formed to be an isosceles triangle. A fourth vent 36 having a larger opening area than the third vent 35 is formed on the lower surface of the rear cylinder portion 34. The fourth vent 36 is also formed by processing after the rear frame 32 is extruded as in the first example. In the third example, a rear vent passage is formed by the third vent 35 and the fourth vent 36.

  The top plate main body 33 is provided with a top plate opening 33a penetrating the front and back. The top plate opening 33 a has an opening area larger than that of the third ventilation hole 35 and has almost the same opening area as that of the fourth ventilation hole 36. And if the back frame 32 is attached to the rear side part of the top plate main body 33, the 4th ventilation port 36 and the top plate opening 33a will connect. As a result, the inside of the stove main body 4 communicates with the outside air through the third vent hole 35, the fourth vent hole 36, and the top plate opening 33a. In addition, since the other structure is the same as that of the said 1st example, the same code | symbol is attached | subjected to drawing in the drawing, and detailed description is abbreviate | omitted.

  Since the glass top plate 31 of the third example has the above-described configuration, when the burner 9 is ignited and burned by the operation knob 9b, the air in the stove body 4 is used as combustion air and combustion is performed. Is called. When the air in the stove body 4 is used in this way, the outside air passes through the second vent 12 opened toward the stove body 4 and the first vents 11 provided on the left and right sides of the front tube portion 7. Is supplied into the stove body 4. At the same time, outside air enters the stove body 4 through the top plate opening 33 a that is opened toward the stove body 4, the fourth vent 36, and the third vent holes 35 provided on the left and right sides of the rear cylinder portion 34. Supplied.

  In the glass top plate 31 of the third example, since the top plate opening 33a and the fourth vent 36 are formed larger than the opening area of the third vent 35, the air supplied from the third vent 35 is not supplied. It can be smoothly fed into the stove body 4.

  Further, the glass top plate 31 of the third example is provided so that the rear cylinder part 34 is positioned on the surface of the top plate main body 33 without the rear frame 8 extending behind the top plate main body 33. For this reason, if the top plate main body 33 having the same outer dimensions as the glass top plate 3 of the first example is used for the glass top plate 31, the depth size of the entire glass top plate 31 can be shortened. It can be installed in a short kitchen. Moreover, since the shape of the rear frame 32 becomes simple, the glass top plate 31 having a clean appearance can be provided.

  Next, a glass top plate 41 as a fourth example of the first embodiment will be described with reference to FIG. The glass top plate 41 of the fourth example is different in the rear frame 42 from the rear frame of the first to third examples. The rear frame 42 in the fourth example is formed of a metal extrusion molding material, and as shown in FIG. 6, a flat plate portion 42c extending horizontally from the second edge 42b having the second groove 42a to the rear. And a hood portion 42d extending obliquely rearward and upward from the second edge portion 42b.

  The flat plate portion 42c is formed with a third vent hole 43 that opens the inside of the stove body 4 to the atmosphere and is processed after extrusion. In the fourth example, a rear vent passage is formed by the third vent 43. A vent guard (not shown) is also attached to the third vent 43. In addition, since the other structure is the same as that of the said 1st example, the same code | symbol is attached | subjected to drawing in the drawing, and detailed description is abbreviate | omitted.

  Since the glass top plate 41 of the fourth example has the above configuration, even if the burner 9 is burned and the air in the stove body 4 is consumed, only the first vent 11 and the second vent 12 are used. In addition, outside air is also supplied into the stove main body 4 from the third vent 43. Moreover, since the 3rd ventilation hole 43 is covered with the food | hood part 42d, even when there is spilling etc. at the time of cooking, the broth etc. do not permeate into the stove main body 4 from the 3rd ventilation hole 43. Further, since the hood portion 42d is opened not only on the rear side but also on the left and right sides, even if the space between the glass top plate 3 and the rear wall surface W is small, the stove main body 4 is provided for the burner 9. A sufficient amount of combustion air can be supplied.

  Next, the glass top plate 51 of 2nd Embodiment is demonstrated with reference to FIG.
