Description

  The present invention relates to a gas stove.

  A gas stove generally has a top plate attached to the upper surface of the gas stove body where the burner is installed, and a burner is inserted into the burner opening formed in the top plate, and five virtues are arranged around the burner. ing. The five virtues include a five virtue frame having a substantially annular shape in a plan view, and a plurality of five virtue claws on which an object to be heated is placed at substantially equal intervals in the circumferential direction of the five virtue frames.

  If the virtues are not arranged in the prescribed position and orientation with respect to the burner, the virtuosity claw may be abnormally heated and burnt out or the heated object cannot be heated with the prescribed thermal power. It is necessary to arrange in the direction. For this reason, the top plate is provided with a locking recess for locking the virtuosity claw, and the virtuosity claw is locked in the locking recess to position the virtues (for example, see Patent Document 1).

  In this case, the top plate (more precisely, the burner ring that closes the gap formed between the burner and the inner edge of the burner opening) is provided with a locking recess corresponding to all five virtue claws. Therefore, the number of the locking recesses is increased, and the wiping and cleaning becomes troublesome and the careability is poor.

  Thus, it has been considered that some of the five virtue claws are provided with a locking protrusion and a locking recess is provided only in a portion corresponding to the locking protrusion. Thereby, it is not necessary to provide locking recesses so as to correspond to all five virtue claws, the number of locking recesses can be reduced, and wiping and cleaning are facilitated, and the careability is improved.

On the outer surface of the lower end portion of the cylindrical portion 31 of the burner ring 3, a fixing plate engaging portion (not shown) that engages with the ring fixing plate 12 described later is provided.

  As shown in FIG. 2, the ring fixing plate 12 is disposed on the lower surface side of the top plate 1 and is attached to the gas stove body or the top plate 1, and has substantially the same shape as the burner opening 10 in a plan view. An opening 12a is formed. A ring fixing plate 12 having the opening 12a formed in the center may be provided for each of the kitchen parts 11, or a single ring having a plurality of the openings 12a corresponding to the kitchen parts 11. The fixing plate 12 may be provided and is not particularly limited. A burner ring engaging portion (not shown) that engages with the fixing plate engaging portion of the burner ring 3 is provided on the periphery of the opening 12 a of the ring fixing plate 12.

  The burner ring 3 is attached to the ring fixing plate 12. In this embodiment, the cylindrical portion 31 of the burner ring 3 is inserted from above the top plate 1 into the burner opening 10 and into the opening 12a of the ring fixing plate 12. The fixing plate engaging part is engaged with and attached to the burner ring engaging part. A concave groove 34a having a ring shape in plan view is formed on the lower surface of the outer flange portion 32 of the burner ring 3, and a sealing member 34b is loaded in the concave groove 34a. When the burner ring 3 is attached to the ring fixing plate 12, the outer flange portion 32 comes into contact with the upper surface of the peripheral edge of the burner opening 10 of the top plate 1. At this time, the seal member 34 b is placed on the upper surface of the top plate 1. The seal is made by pressure contact. The top surface portion is constituted by the burner ring 3 and the top plate 1 attached in this manner.

  The top surface portion is provided with a locking recess 35 in which the locking protrusion 43 of the above-mentioned five virtues 4 is locked. In this embodiment, as shown in FIG. 5, the upper surface of the outer flange portion 32 of the burner ring 3 is provided. In addition, a locking recess 35 for locking the locking protrusion 43 is provided. The locking recess 35 is formed to have a width that is substantially the same as or slightly wider than the thickness of the locking protrusion 43 and is substantially the same as or slightly longer than the length of the locking protrusion 43. , Which has a plurality of stepped portions whose width gradually decreases, will be described below.

  As shown in FIG. 5 (b), the stepped portion has a first width portion 35a having a width W2 that is substantially the same as or slightly wider than the thickness of the smoked virtuosity claw 42 (and the locking projection 43), It consists of a second width portion 35b having a width W1 which is narrower than the one width portion and substantially the same as or slightly wider than the thickness of the metal virtuosity claw 42 (and the locking projection piece 43).

  And when arranging the 5 virtues 4 provided with the metal virtues claw 42, when the locking protrusion 43 is locked to the locking recess 35 as shown in FIG. It is positioned over the entire length of 35a and the second width portion 35b and is inserted into the second width portion 35b which is substantially the same as or slightly wider than the locking protrusion 43 and is positioned without rattling. Thus, the length of the locking protrusion 43 is formed to be a length located in the first width portion 35a and the second width portion 35b.

  Further, when the virtues 4 having the smoked virtuosity claw 42 are arranged, the first width portion when the locking projection 43 is locked to the locking recess 35 as shown in FIG. Positioned in the first width portion 35a located at 35a and substantially the same as or slightly wider than the locking projection 43, positioning is performed without rattling. As described above, the length of the locking protrusion 43 is formed to be a length located only in the first width portion 35a.

  By doing in this way, since the locking protrusions 43 having different thicknesses can be locked to the locking recesses 35, a plurality of locking recesses 35 having different widths depending on the locking protrusions 43 having different thicknesses. There is no need to manufacture the top surface (ie, burner ring 3).

  Further, in the present embodiment, the five-virtual frame 41 is provided with a non-circular shape in plan view and a five-virtual frame engaging portion capable of engaging the five-virtual frame 41 from above with the outer flange portion 32 of the burner ring 3.

  In this embodiment, as shown in FIGS. 3 and 4, the virtually frame 41 is formed in a plan view shape with a part of the annular circumferential direction as an arc, and the remaining part is formed by extending the arc. In particular, in the illustrated example, the two arcuate portions 41a on the same circle having a central angle of about 150 degrees are opposed to each other, and the distance is slightly separated. The end portions on the same side of the arc-shaped portion 41a are connected by a straight line portion 41b to be a point-symmetric shape. The central angle of the arcuate portion 41a may not be 150 degrees.

  As shown in FIG. 5, the burner ring 3 forms an arcuate portion 32 a and a rectilinear portion 32 b corresponding to the arcuate portion 41 a and the rectilinear portion 41 b of the virtually frame 41, and The shape is formed in substantially the same shape as the plan view of the virtuosity frame 41, and this outer peripheral edge functions as the virtuosity frame engaging portion.

  As shown in FIG. 6, the inner peripheral edge of the five virtue frame 41 fits and engages with the outer peripheral edge of the outer collar portion 32 of the burner ring 3. Since the outer shape of the outer frame portion 32 of the virtuosity frame 41 and the burner ring 3 is non-circular, the virtues 4 are positioned with respect to the burner ring 3 when the virtues 4 and the burner ring 3 are engaged. It cannot be rotated relative to the circumferential direction.

  Further, since the outer shape of the outer flange portion 32 of the burner ring 3 is substantially the same as the plan view shape of the five virtue frame 41, the predetermined orientation of the five virtue frame 41 with respect to the burner ring 3 can be seen at a glance. It is easy to match the direction of the to a predetermined direction.

  Further, by making the shape of the virtuosity frame 41 in a plan view a combination of an arc and a straight line, the virtuosity frame 41 can be manufactured with a slight modification from the conventional annular virtuosity frame, and the design is easy. It becomes.

  In addition, by making the shape of the virtuosity frame 41 in a point-symmetrical shape, the virtues 4 can be engaged even if they are inverted by 180 degrees, and the work of arranging the virtues 4 becomes easy.

  Moreover, in this embodiment, as shown in FIG. 8, the ring cover 5 which covers the upper surface of the burner ring 3 is provided. As a result, even if the broth spills from the pan during cooking, the dirt does not adhere to the burner ring 3 but adheres to the ring cover 5, so that only the ring cover 5 needs to be washed and the careability is improved. Is.

  Furthermore, the ring cover 5 is arranged between the outer periphery of the burner 2 (specifically, the outer periphery of the burner body 22) and the inner periphery of the virtuosity frame 41. It will be better. A notch 51 for releasing the locking protrusion 43 is formed in a portion corresponding to the locking protrusion 43.

  In the present embodiment, the ring cover 5 is disposed on the upper surface of the burner ring 3 with a gap therebetween, thereby eliminating the heat conduction from the ring cover 5 to the burner ring 3 and increasing the temperature of the burner ring 3. It can be suppressed, and when the burner ring 3 is contaminated, it becomes difficult for the dirt to stick.
