Description

  The present invention relates to a glass top plate for a stove, and more particularly, to a glass top plate for a stove in which an upper open portion of a stove body is covered and an opening for a heat source is formed at a position corresponding to the heat source.

FIG. 6 shows a glass top plate (3) covering the main body (31) of the drop-in stove to be fitted into the countertop (32) of the system kitchen and the upper open portion thereof, and the upper side of the glass top plate (3). FIG. 5 is an enlarged cross-sectional view showing a part of the five virtues (5) projecting from the gas top plate (3), and a gas burner (FIG. 5) as a heating source housed in the stove body (31). A heat source opening (30) is formed at a position corresponding to (not shown). A protective ring (4) is attached to the periphery of the heat source opening (30) in order to prevent cracking and the like.
The protective ring (4) is an upper ring provided with a cylindrical portion (41a) that covers the upper surface in the vicinity of the periphery of the heat source opening (30) via a packing (40) and is inserted into the heat source opening (30). (41) and a lower ring (42) that covers the lower surface near the periphery of the heat source opening (30) via a packing (40), and the cylindrical portion (41a) of the upper ring (41) A through hole (45) for inserting a fixing projection (51) projecting downward from the lower end of Gotoku (5) is formed in the vicinity of the base end of From the lower end of 41a), a flange piece (41b) is stretched into the heat source opening (30).

Conventionally, in order to fix the upper ring (41) and the lower ring (42) in a non-rotating state, as shown in FIG. 7, a plurality of portions of the flange piece (41b) of the upper ring (41) are moved downward. The cut-and-raised piece (43) having a substantially L-shaped cross-section is formed, and the latched pieces are engaged with the cut-and-raised pieces (43) from the inner peripheral edge of the lower ring (42). There is a configuration in which a piece (44) is projected.
The upper ring (41) and the lower ring (42) are attached to the peripheral edge of the heat source opening (30), and are rotated relative to each other in a predetermined direction, whereby the flange piece (41b) of the upper ring (41) is attached. The locking piece (44) of the lower ring (42) is locked to the cut and raised piece (43) provided, so that the upper ring (41) and the lower ring (42) are fixed in a non-rotating state. .

However, in the conventional protection ring (4), the flange piece (41b) provided on the upper ring (41) has a hole (46) for raising the cut-and-raised piece (43). In addition to being unsightly exposed under the five virtues (5), there are inconveniences that dirt such as boiled spills enters the holes (46). Also, when the cut and raised piece (43) is caulked to the locking piece (44), the flange piece (41b) of the upper ring (41) is wavy, which is also unsightly exposed in the virtues (5). It will be a thing.
Further, in the above-mentioned conventional one, the cut and raised piece (43) provided on the upper ring (41) and the locking piece (44) provided on the lower ring (42) are the upper ring (41) and the lower ring (41). Since it is set so as to function as both a rotation prevention means and a connection means with respect to the ring (42), when a force that shifts in the circumferential direction with respect to the lower ring (42) acts on the upper ring (41), the caulking The rotational load is directly applied to the part. This affects the connection state between the two, and in some cases, the locking state between the cut-and-raised piece (43) and the locking piece (44) is loosened or disconnected. In addition, there is a disadvantage that the cut and raised piece (43) is caught on a cloth or the like during cleaning.

  The present invention is “a glass top plate that covers an upper open portion of a stove body in which a heating source is accommodated, and an opening for the heat source is formed at a location corresponding to the heating source. In the glass top plate for a stove in which a protective ring comprising an upper ring and a lower ring is mounted on the periphery of the opening, and the virtues are placed above the upper ring, the stove body in the protective ring mounted state It is an object of the present invention to improve the external appearance and to prevent the rotational load applied to the upper ring or the lower ring from affecting the joint portion between them.

(1) The top plate for a stove of the invention according to claim 1 is provided such that an upper flange piece and a lower flange piece projecting into the heat source opening are provided on the upper ring and the lower ring, respectively.
An opening is formed at each of the upper flange piece and the lower flange piece facing each other in the vertical direction,
A rising wall that extends toward the other opening and can be inserted into the other opening is formed at the periphery of the opening of either the upper flange piece or the lower flange piece,
In the space surrounded by the upright wall, a fixing projection protruding downward from the lower end of the five virtues can be inserted,
A connecting piece is formed on the inner peripheral edge of the upper flange piece so as to be engaged with the inner peripheral edge of the lower flange piece so as to connect the upper ring and the lower ring. .
The above means operates as follows.
An upper ring is attached to the upper surface periphery of the heat source opening provided on the glass top plate, and a lower ring is attached to the lower surface periphery. At this time, the rising wall formed on one of the upper flange piece and the lower flange piece extending from the both into the heat source opening is inserted into the opening formed on the other. Thereby, even if it is going to rotate an upper ring with respect to a lower ring, both will be in the rotation prevention state in the circumferential direction, when a standing wall contact | abuts to an opening part in the rotation stop state. In this inserted state, the connecting piece provided on the upper flange piece is bent and locked to the inner peripheral edge side of the lower flange piece. Thereby, the upper ring and the lower ring are connected in the vertical direction. The upper ring opening is exposed on the upper surface of the protective ring mounted as described above, and the five virtue fixing protrusions are inserted into the opening.

(2) In claim 1, "the upper flange piece and the lower flange piece are annular bodies projecting from the entire inner peripheral edge of the upper ring and the lower ring,
The opening is a notch formed so as to open inward at each position facing the center of each of the upper flange piece and the lower flange piece,
The upright wall is formed along at least the circumferentially facing portion of the notch formed in the upper flange piece '', the upright wall provided in the notch of the upper flange piece is The upright wall is brought into contact with a portion of the lower flange piece that is inserted into the notch and is opposed to the circumferential direction of the notch of the lower flange piece. Therefore, the relative rotation of the upper ring and the lower ring in the circumferential direction is prevented. The notches are formed at positions facing the centers of the upper ring and the lower ring, and a pair of fixing protrusions provided at the positions facing the virtues are respectively inserted into the notches.

(3) In claim 2, "the rising wall is formed over the entire inner circumference of the upper flange piece,
The rising wall is set so as to be located inward from the inner peripheral edge of the lower flange piece, and the connecting pieces are projected at a plurality of locations on the extended end side of the rising wall. '' When the protective ring is attached, the rising wall provided on the entire inner peripheral edge of the upper flange piece of the upper ring is positioned inward of the lower flange piece of the lower ring, The peripheral edge is entirely covered with the rising wall. In this state, the connecting piece protruding from the edge of the rising wall is bent toward the lower flange piece so that the connecting piece can be locked to the back side of the lower flange piece.

  According to the first aspect of the present invention, in a state where the protective ring is attached to the periphery of the heat source opening, the opening formed in the upper flange piece of the upper ring is exposed in the heat source opening of the top plate. However, when the fixing protrusion for virtues is inserted into the opening, the opening is not exposed below the virtues. Further, since the connecting piece is locked to the back surface side of the lower flange piece of the lower ring and crimped, undulation due to the crimping that appeared on the upper ring can be reduced. By these, the beauty | look of a stove can be improved.

  In addition, the upright wall provided on either the upper flange piece or the lower flange piece and the opening into which the upper wall is inserted function as a circumferential detent means for the upper ring and the lower ring. Since the engagement of the connecting piece with the lower flange piece functions as a connecting means in the vertical direction of the upper ring and the lower ring, for example, a force that causes the upper ring to shift in the circumferential direction with respect to the lower ring acts. Even so, the accompanying rotational load is received by the rising wall and the periphery of the opening, and does not affect the locking state of the connecting piece. In other words, there is no inconvenience that the upper ring and the lower ring are disconnected even when a rotational load is applied.

  According to the second aspect of the present invention, since the opening is formed by the notch, the opening and the rising wall can be easily formed in the upper flange piece and the lower flange piece, and the positioning is easy. Further, since the rising wall is provided on the upper ring side, the peripheral edge of the notch of the lower ring is covered with the rising wall when the protective ring is mounted, and the aesthetics are further improved. Furthermore, the notches are formed at respective positions opposed to the centers of the upper ring and the lower ring, and the fixing protrusions for the five virtues are inserted into each of the notches. In this state, since the five virtues are unstable with respect to the top plate, it can be confirmed that the five virtues are in an erroneous setting state, and can be reliably prevented from being used in the erroneous setting state.

  Further, according to the invention according to claim 3, the rising wall provided in the entire inner peripheral edge of the upper flange piece can surround the inner peripheral edge of the lower flange piece over the entire area. There is no exposure of burrs formed by punching formed on the inner periphery. Therefore, the aesthetics are further improved, and there is no inconvenience of being injured by catching a hand on the burr even if the hand is put in the protective ring during assembly or cleaning.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
