Description

  The present invention relates to a cooking stove that covers an exhaust port opened on a top plate communicating with a grill cabinet with an exhaust port cover.

  In a cooking stove that has a grill cabinet for roasting fish etc. in the stove body, an exhaust port communicating with the grill cabinet is provided on the top plate on the top surface of the stove body, so that oil smoke generated in the grill cabinet Combustion exhaust is discharged to the outside through the exhaust port.

  In general, the exhaust port is provided with an exhaust port cover so as to cover the exhaust port in order to prevent intrusion of cooking juice, dust and the like from the top plate into the grill. As this type of exhaust port cover, a metal base material made of iron or the like formed in a tray shape or the like having a vent hole for allowing combustion exhaust gas or the like to pass through on the upper surface and opening downward according to the shape of the exhaust port. In order to improve the aesthetics and prevent the top plate from being scratched, a material that has been dipped in a glaze and the surface of which has been wrinkled is widely used.

  However, if the lower end portion of the exhaust port cover that is in contact with the top plate is an end surface, it is difficult for the glaze to sufficiently adhere to the end surface. Since the exhaust port cover needs to be detachably disposed on the top plate for cleaning or the like, the exhaust port cover is likely to be loose at the opening periphery of the exhaust port. As a result, in the case of a cooking stove having a stainless steel top plate or the like, there is a problem that the end surface of the rough metal base material is rubbed against the top plate, and the top plate is significantly damaged.

  In order to prevent the top plate from being damaged by rubbing the exhaust port cover, for example, an L-shaped attachment member having a rib extending inward from the lower end and a hanging portion extending downward from the rib is provided at the lower end. A cooking stove has been proposed that has a plurality of exhaust port covers provided on the sides facing each other in the front-rear direction (for example, Patent Document 1). According to this cooking stove, since the flat surface of the rib is grounded to the top plate, the top plate can be prevented from being damaged even if the exhaust cover is rubbed against the top plate.

Japanese Utility Model Publication No. 5-19815

  However, if a metal base material having a mounting member extending downwardly in an L shape from the lower end as described above is subjected to glaze processing, the glaze accumulates due to surface tension at the corners of the ribs and hanging parts, and firing After the treatment, a pit is formed in the corner portion. As a result, there is a difference in the height of the flat surface of the rib that comes in contact with the top plate, and there is a problem that rattling tends to occur in the height direction.

  Moreover, in the exhaust port cover of patent document 1, since the attachment member is provided in the side which opposes the front-back direction of a lower end part, the drooping piece part is adjoining to the opening end of an exhaust port, and an exhaust port cover As the exhaust cover is detachably installed on the top plate, it can be easily moved when the cooking container comes into contact with the exhaust cover. Therefore, the exhaust port cover as in Patent Document 1 has a problem that the exhaust port cover is likely to be loose in the left-right direction. In this case, it is conceivable to provide attachment members not only on the front and rear sides of the lower end of the exhaust port cover, but also on the lateral sides. The difference becomes large, and the play in the height direction tends to occur.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and the object of the present invention is to prevent the inconvenience that the lower end portion of the exhaust port cover rubs against the top plate and damages the top plate. An object of the present invention is to provide a cooking stove that can be installed in a stable state without rattling on the top board.

The present invention includes a grille, a top plate provided with an exhaust port communicating with the grille, and a downwardly opened exhaust port cover that is detachably installed on the top plate so as to cover the exhaust port. A cooking stove having,
The exhaust port cover includes an upper surface portion in which a ventilation port is formed, and a side wall that extends downward from a peripheral edge of the upper surface portion and forms a substantially oval or substantially rectangular lower end portion larger than the exhaust port. Have
The exhaust cover is entirely wrought,

  What is shown in FIG. 1 is a gas stove 1 with a grill of a rear exhaust type, and a grill cabinet 2 for heating and cooking an object to be cooked such as fish is disposed in the stove body. A grill door 21 that can be opened and closed is provided in front of the grill cabinet 2. When the grill door 21 is pulled out, the grill pan 23 in the grill cabinet 2 is pulled out together with the grill 22.

  An upper fire burner 24 is provided in the upper portion of the grill cabinet 2, and a lower fire burner 25 is provided along the front-rear direction below the left and right side walls of the grill cabinet 2 below the grill net 22. The upper fire burner 24 is composed of a surface combustion type burner having a ceramic combustion plate in which a large number of flame holes are formed, and is arranged in the upper portion of the grill cabinet 2 with the combustion plate directed downward. The lower fire burner 25 is composed of a Bunsen type burner, and is disposed below the left and right side walls with a plurality of flame holes directed toward the center of the grill cabinet 2.

  An exhaust cylinder 26 through which oil smoke generated in the grill warehouse 2 and combustion exhaust from the upper fire burner 24 and the lower fire burner 25 flows is provided at the rear of the grill warehouse 2, and the downstream end of the exhaust cylinder 26 is The exhaust port 30 is opened in the top plate 3 of the stove body. An exhaust port cover 5 is detachably installed on the top plate 3 so as to cover the exhaust port 30 from above.

  As shown in FIG. 2, the exhaust port cover 5 according to the embodiment of the present invention has a substantially rectangular upper surface portion 51 in which a large number of vent holes 53 are formed, and extends downward from the periphery of the upper surface portion 51. It has a side wall 52 and has a thin tray shape that is open downward. In addition, the exhaust port cover 5 is dipped in the glaze by immersing a metal base material formed in the above-mentioned shape in a glaze and firing, so that the lower end portion 54 of the exhaust port cover 5 is provided. Is formed in a substantially rectangular shape slightly larger than the exhaust port 30.

  As shown in FIG. 2 and FIG. 3, the front ends of the side walls 52 constituting the lower end portion 54 are inwardly hemmed on each of the two sides facing each other in the front-rear and left-right directions of the lower end portion 54. The top plate grounding portion 55 formed by the above is provided in the entire area excluding the backlash restricting claw portion 57 and both ends thereof. Thereby, even if the exhaust port cover 5 is displaced on the top plate 3, the top plate 3 is prevented from being damaged even if the end surface of the metal base material is not exposed to the lower end portion 54. Further, since the top plate grounding portion 55 is formed on each of the two opposing sides of the lower end portion 54, the exhaust port cover 5 is prevented from being tilted when the exhaust port cover 5 is installed on the top plate 3. And can prevent backlash. In addition, you may provide the top-plate grounding part 55 in at least 1 set of each side of 2 sets of each side which mutually opposes in the front-back and left-right direction of the lower end part 54. FIG.

  The method of forming the top plate grounding portion 55 by bending the front end of the side wall 52 is not particularly limited as long as the end surface of the metal base material to which the glaze is difficult to adhere is not exposed to the lower end portion 54 after the glazing. . For example, the top plate grounding portion 55 may be formed by curling the tip of the side wall 52. Further, as will be described later, a top plate grounding portion having a folded portion that is bent so as to extend the tip of the side wall 52 inward may be formed.

  The length of the top plate grounding part 55 is not particularly limited as long as the exhaust port cover 5 can be stably installed on the top plate 3, but as shown in FIG. If the top plate grounding portion 55 is formed almost in the entire central portion, the exhaust port cover 5 can be installed in a more stable state, and the gap between the top plate 3 and the exhaust port cover 5 is reduced in front view. The beauty of 1 can be improved. In addition, as long as the top-plate grounding part 55 is provided in the opposite side, you may provide the top-plate grounding part 55 in which length differs in each side.

  As shown in FIG. 2, the exhaust port cover 5 has play-restricting claw portions 57 on each side of the lower end portion 54 facing each other in the front-rear direction and at both ends in the left-right direction. The backlash restricting claw portion 57 includes a protruding piece portion 57a bent so as to protrude inwardly from the side wall 52 constituting the lower end portion 54, and a protruding end of the protruding piece portion 57a into the exhaust port 30. It has a hanging piece portion 57b that is bent so as to hang down, and is formed in a substantially L shape in a sectional view.

  As shown in FIG. 3, the drooping piece portion 57 b is provided so that the outer surface of the drooping piece portion 57 b is located in the vicinity of the opening end 30 a of the exhaust port 30. Thereby, even if the exhaust port cover 5 is moved in the front-rear direction, the drooping piece portion 57b contacts the opening end 30a of the exhaust port 30, so the drooping piece portion 57b and the opening end 30a of the exhaust port 30 face each other. Can be prevented.

  Further, the lower surface of the top plate grounding portion 55 is provided so as to be positioned below the exhaust port 30 side with respect to the lower surface of the protruding piece portion 57a. As described above, when the exhaust port cover 5 that has been glazed is produced, the metal piece having the bent piece 57a and the hanging piece 57b that has been bent is immersed in the glaze. The glaze is accumulated by the surface tension at the corner portion between 57a and the hanging piece portion 57b, and the glaze pool is formed. As a result, each protruding piece portion 57a provided for backlash regulation is formed to have horizontal surfaces with different heights. Therefore, when the projecting piece 57a is grounded to the top plate 3, the exhaust port cover 5 is likely to be loose.

  On the other hand, according to the exhaust port cover 5 of the present embodiment, the lower surface of the top plate grounding portion 55 is positioned at the lowest end on the top plate 3 in the height direction, and the lower surface of the top plate grounding portion 55 is Since it is provided so as to be positioned below the lower surface of the protruding piece portion 57a of the backlash regulating claw portion 57, it is possible to prevent backlash due to wrinkling.

  The difference in height between the lower surface of the top plate grounding portion 55 and the lower surface of the protruding piece portion 57a is not particularly limited as long as it is larger than the height of the ridges to be formed, although it varies depending on the heel processing conditions.

  As long as the play restricting claw portion 57 is provided on the opposite side of the lower end portion 54, it may be provided on the same side as the set on which the top plate grounding portion 55 is provided. It may be provided on a different set of sides. As shown in FIG. 2, when the top plate grounding portion 55 and the backlash restricting claw portion 57 are formed on the same side, the top plate grounding portion 55 and the backlash restricting claw portion are formed at the lower end portion 54. A notch 58 is formed between the first and second portions 57. As a result, the top plate grounding portion 55 and the backlash regulating claw portion 57 can be formed discontinuously, and the bottom surface of the topplate grounding portion 55 is lower than the bottom surface of the protruding piece portion 57a of the backlash regulating claw portion 57. Can be formed.

  As shown in FIG. 4, the exhaust port 30 has a horizontally long oval shape in which the opening end 30a is composed of a pair of linear long sides and a pair of arcuate short sides, and the long side is a ceiling. It is formed along the long side of the plate 3. The exhaust port cover 5 is installed so as to cover the entire exhaust port 30. The exhaust port 30 may have a substantially rectangular shape in which the opening end 30a includes a pair of linear long sides and a pair of linear short sides in accordance with the shape of the exhaust cylinder 26 and the purpose of use. Alternatively, the four sides may have a substantially square shape having substantially the same length.

  In addition, a projection 31 that protrudes inward is formed at the opening end 30 a of the exhaust port 30. When the exhaust port cover 5 is installed on the exhaust port 30 at the opening end 30 a in the front-rear direction of the exhaust port 30, the protrusion 31 is formed on the side portion 57 c of the hanging piece portion 57 b of the backlash restricting claw portion 57. It is provided in the position which can be engaged. Thereby, backlash in the lateral direction of the hanging piece portion 57b can be prevented.

  FIG. 5 is a schematic perspective view showing another example of the exhaust port cover according to the present embodiment. In addition, about the part same as FIG. 2, description is abbreviate | omitted using the same code | symbol.

  As shown in FIG. 5, the exhaust port cover 5 a includes a top plate grounding portion 55 a having a folded portion extending inwardly formed by bending the front end of the side wall 52 constituting the lower end portion 54. ing. The top plate grounding portion 55a is formed such that the lower surface of the folded portion is positioned below the lower surface of the protruding piece portion 57a of the backlash restricting claw portion 57 in the same manner as described above. By providing the top plate grounding portion 55a having such a folded portion, the plane of the folded portion is grounded to the top plate 3, so that the top plate 3 can be prevented from being damaged due to rubbing of the exhaust port cover 5a. Particularly, according to the exhaust port cover 5a, the top plate grounding portion 55a can be formed by bending only a part of the lower end portion 54.
