Description

[0001]
BACKGROUND OF THE INVENTION
The present invention comprises a glass top plate for a stove comprising a glass plate provided with a plurality of stove openings for facing a heat source such as a burner, and a protective ring attached to each stove opening, and the glass top plate. Concerning the stove.
[0002]
[Prior art]
Although the glass top plate is excellent in appearance and cleanability, the opening edge of the stove opening established in the glass plate is vulnerable to impact, so conventionally a metal protective ring was attached to the stove opening to protect the opening edge. What you do is known.
[0003]
Here, the protective ring includes a cylindrical portion inserted into the stove opening, and upper and lower flange portions that are opposed to the upper and lower surfaces of the glass plate and are connected via the cylindrical portion. And in order to prevent that a cylinder part press-contacts to the opening edge of a stove opening by thermal expansion, it inserts in a stove opening in the state which left the clearance gap around. The upper flange portion and the lower flange portion are respectively seated on the lower surface and the upper surface of the glass plate via packing.
[0004]
[Problems to be solved by the invention]
The conventional protection ring moves relative to the glass plate because there is a gap between the cylindrical portion and the opening edge of the stove opening. The packing is rubbed due to the shift of the protective ring, and the wear tends to occur.
Even if the five victories placed on the glass plate are locked so as not to move relative to the protective ring, the five victories move together with the protective ring. In particular, the rotation of the protective ring cannot be restricted, and if the pan is shaken so as to rotate on the virtues, the virtues will also rotate, giving the user a sense of incongruity.
[0005]
In view of the above points, the present invention provides a glass top plate that can regulate the movement of the protective ring relative to the glass plate and a stove in which the virtues are prevented from moving by using this glass top plate. It is an issue.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, according to the present invention, a glass plate provided with a plurality of stove openings for exposing a heating source is provided, and each stove opening is inserted with a surrounding gap in each stove opening. A glass top plate for a stove comprising a plurality of protective rings each having a cylindrical portion and upper and lower flange portions that are connected to each other via the cylindrical portion and that are opposed to the upper and lower surfaces of the glass plate. A plurality of protection rings attached to the openings are connected to each other at the lower flange portion of these protection rings.
[0007]
According to said structure, even if each protection ring tries to rotate, the other protection ring connected with this will contact | abut to the opening edge of a corresponding stove opening, and rotation of each protection ring is blocked | prevented. In addition, unlike the case where the plurality of protection rings are independent of each other, the force obtained by adding the frictional forces acting between the protection rings and the glass plate for the plurality of protection rings is the resistance to the displacement of each protection ring. Therefore, the movement of each protection ring relative to the glass plate can be effectively restricted.
[0008]
By the way, it is conceivable to connect the lower flange portions of the plurality of protection rings with bars, but this increases the number of parts and increases the cost. On the other hand, if the lower flange portions of the plurality of protective rings are integrally formed of a common plate material disposed on the lower surface side of the glass plate, the number of parts can be reduced and the cost can be reduced, which is advantageous.
[0009]
Here, in the stove where each virtues are placed so as to surround each stove opening on the glass plate of the glass top plate, the glass top plate of the present invention is used, and each virtues are attached to the upper flange portion of each protection ring. If you lock it so that it does not move relative, you can regulate the movement of each virtue relative to the glass plate, and even if you shake the pan on the virtue, the virtue does not rotate, giving the user a sense of incongruity Absent.
[0010]
In addition to the five victories, each cover ring that covers each protective ring may be provided on the glass plate. In this case, each cover ring is not required to be directly locked to the upper flange portion of the protective ring. Is locked so as not to move relative to the upper flange portion of each protective ring, and each virtues are locked so as not to move relative to each cover ring, thereby restricting the movement of each virtues relative to the glass plate.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a stove provided with a glass top plate 1. The glass top plate 1 is composed of a glass plate 2 made of ceramic glass and a metal outer frame 3 surrounding the glass plate 2, and a support body (a counter top in a built-in stove and a table top stove in a built-in stove). It is supported by the stove body.
[0012]
The glass plate 2 is provided with a total of three stove openings 5 on both the left and right sides and the rear center where the burner 4 as a heating source faces, and each of the five virtues 6 is enclosed on the glass plate 2 so as to surround each stove opening 5. Is placed.
[0013]
Here, a protection ring 7 made of metal such as stainless steel is attached to each stove opening 5 as shown in FIG. 2 in order to protect the opening edge. The protection ring 7 includes a cylindrical portion 70 that is inserted into the stove opening 5 with a peripheral gap, an upper flange portion 71 that faces the upper surface of the glass plate 2, and a lower flange portion that faces the lower surface of the glass plate 2. 72. The cylinder part 70 has an inner / outer double structure of an inner cylinder 70 a integrated with the upper flange part 71 and an outer cylinder 70 b integrated with the lower flange part 72. Then, cutout claws 70c projecting inward are formed at a plurality of locations in the circumferential direction of the outer cylinder 70b, engagement holes 70d are formed at a plurality of locations in the circumferential direction of the inner cylinder 70a, and the inner cylinder 70a is formed in the outer cylinder 70b. When internally fitted, each cut-out claw 70c is engaged with each engagement hole 70d, the inner cylinder 70a is immovably locked to the outer cylinder 70b, and the upper and lower flange portions 71 and 72 are interposed via the cylinder portion 70. It is supposed to be connected.
[0014]
Further, the upper flange portion 71 and the lower flange portion 72 are seated on the lower surface and the upper surface of the glass plate 2 through packing 73, respectively, in order to prevent the glass plate 2 from being damaged. When the inner cylinder 70a is locked to the outer cylinder 70b as described above and the protective ring 7 is attached to the stove opening 5, the packing 73 is compressed, and the frictional force acting between the packing 73 and the glass plate 2 is applied. The movement of the protective ring 7 relative to the glass plate 2 is restricted to some extent. In addition, the packing 73 opened between the upper flange part 71 and the upper surface of the glass plate 2 is piled up two sheets. Further, on the glass plate 2, each cover ring 8 for covering the protective rings 7 is provided.
Note that the burner 4 on the left side of the stove shown in FIG. 2 is configured so that the flame from the inward flame hole 4b formed in the annular burner main body 4a passes through the guide 4c disposed above the burner main body 4a. It consists of an internal flame burner that leads to the inner space. The burner 4 on the back side of the stove is also an internal flame type burner, but the burner 4 on the right side of the stove is composed of an external flame type burner with a pan bottom temperature sensor 4d.
[0015]
The five virtues 6 are composed of an annular five virtue frame 60 formed of a round bar, which is seated on the glass plate 2, and a plurality of, for example, six five virtue claws 61 fixed to the five virtue frames 60. Further, six engaging holes 71a are formed in the upper flange portion 71 of the protective ring 7 at the same pitch as the five virtue claws 61, and protrusions 61a extending downward are formed on the respective five virtue claws 61 to cover the respective projections 61a. By engaging each engagement hole 71a through each of the through holes 8a formed at the same pitch as that of the five virtue claws 61 on the ring 8, the virtue 6 is locked so as not to move relative to the upper flange portion 71 of the protective ring 7. ing.
[0016]
However, since the protective ring 7 can move against the frictional force of the packing 73 by the gap between the cylindrical portion 70 and the opening edge of the stove opening 5, when the pan is moved on the virtues 6, , The protective ring 7 is displaced, and due to this displacement, the packing 73 is rubbed and worn by the edge of the opening edge of the stove opening 5. Moreover, if it shakes so that a pan may be rotated on Gotoku 6, Gotoku 6 will rotate with the protection ring 7, and will give a user an uncomfortable feeling.
[0017]
Therefore, in the present embodiment, as clearly shown in FIG. 3, a plate material 74 that extends over the opening of the three stove openings 5 is disposed on the lower surface side of the glass plate 2, and is attached to these stove openings 5. The lower flange portions 72 of the individual protective rings 7 are integrally formed of a plate material 74. According to this, the three protective flanges 7 are connected to each other via the plate material 74 in the lower flange portion 72, and the frictional force acting between each protective ring 7 and the glass plate 2 is reduced to three. The total force with respect to the protection ring 7 becomes a resistance force against the displacement of each protection ring 7. Therefore, the displacement of each protective ring 7 with respect to the glass plate 2 can be suppressed, and wear of the packing 73 can be effectively prevented. Moreover, even if each protection ring 7 tries to rotate, the other protection ring 7 connected to the contact comes into contact with the opening edge of the corresponding stove opening 5 and the rotation of each protection ring 7 is prevented. Therefore, even if it shakes so that a pan may rotate on Gotoku 6, Gotoku 6 does not rotate and does not give a sense of incongruity to a user.
[0018]
By the way, the glass plate 2 is colored in a dark color so that the inside of the stove cannot be seen. However, when light from the periphery of the stove enters the stove and reaches the glass plate 2, the glass plate 2 is partially brightened. It gives anxiety to the user. Further, the upper surface of the glass plate 2 is provided with a reinforced coating and is resistant to impact, but the lower surface of the glass plate 2 is weak against impact. In this case, if the plate member 74 is extended over substantially the entire lower surface of the glass plate 2, it is useful for shielding light from below the glass plate 2 and protecting the lower surface of the glass plate 2.
[0019]
By the way, in the said embodiment, the latching means which latches the morality 6 so that it may not move relatively with respect to the upper flange part 71 of the protection ring 7 engages with this with the engagement hole 71a formed in the upper flange part 71. Although it comprised with the protrusion 61a of the virtuosity nail | claw 61, in this thing, simmering may penetrate | invade between the protection ring 7 and the glass plate 2 from the engagement hole 71a.
[0020]
Here, if the plurality of protection rings 7 are connected to each other at the lower flange portion 72 so that the movement of each protection ring 7 can be regulated, the cover ring 8 is made relatively to the upper flange portion 71 of the protection ring 7. By locking so as not to move and locking the virtues 6 so as not to move relative to the cover ring 8, the movement of the virtues 6 can be restricted as in the above embodiment. 4 and 5 show such an embodiment. In this case, the five virtues 6 are of a five-claw type, and the outer periphery of the upper flange portion 71 of the protective ring 7 is formed in a square shape, for example, a decagonal shape, and a cut-and-raised piece 8b bent downward is formed in the cover ring 8. Five pieces are formed at an equal pitch in the circumferential direction, and these cut-and-raised pieces 8b are engaged with every other five sides of the outer periphery of the upper flange portion 71 of the protective ring 7 so that the cover ring 8 is protected. The upper flange portion 71 is locked so as not to move relative to the upper flange portion 71. The cover ring 8 is formed with a total of five engagement holes 8c located on the outer side between the outer peripheral sides of the upper flange portion 71 with which the cut and raised pieces 8b are engaged. The protrusions 61 a formed in the above are engaged with the respective engagement holes 8 c so that the virtues 6 are locked so as not to move relative to the cover ring 8. According to this, since it is not necessary to form the engagement hole 71 a in the upper flange portion 71 of the protective ring 7, the spilled portion does not enter between the protective ring 7 and the glass plate 2.
[0021]
The outer periphery of the cover ring 8 is formed in a rectangular shape that fits into the rectangular outer peripheral shape of the upper flange portion 71 of the protective ring 7 so that the cover ring 8 does not move relative to the upper flange portion 71 of the protective ring 7. In addition to stopping, it is also possible to form contact portions in contact with the respective sides of the outer periphery of the cover ring 8 on the virtues 6 so that the virtues 6 are locked so as not to move relative to the cover ring 8. Further, when the cover ring 8 is omitted, contact portions that contact each side of the outer periphery of the upper flange portion 71 of the protective ring 7 are formed on the virtues 6, and the virtues 6 are formed on the upper flange portion 71 of the protective ring 7. You may lock so that it may not move relatively.
