Description

  The present invention includes a stove body, a top plate made of steel plate that covers the stove body from above, and has been subjected to surface treatment for rust prevention on both the upper and lower sides, and a flange portion and a top plate formed on the upper edge of the stove body. The present invention relates to a stove including a sheet metal member having a fixed portion sandwiched therebetween.

  Conventionally, in a stove with a grill, according to Patent Document 1, a heat shield plate, which is a plate-like component positioned above the grill, is sandwiched and fixed between a flange portion formed on an upper upper edge of the stove body and a top plate. This is known. In this case, a receiving metal fitting is provided that overlaps the front end of the heat shield plate that is seated on the upper surface of the flange portion, and the front metal plate is pressed downward with the top plate so that the front end of the heat shield plate is connected to the flange portion and the top plate. It is made to pinch | interpose through a receiving metal fitting.

  It should be noted that the same method as described above can be adopted for fixing plate-like components other than the heat shield plate. In order to reduce the number of parts, a fixing part having a portion corresponding to a metal fitting is formed on a plate-like part, and the fixing part is sandwiched between the upper flange part of the stove body and the top plate. Conceivable.

  In this way, if the fixing portion of the plate-like component is sandwiched between the flange portion and the top plate, the plate-like component can be fixed without requiring screwing work, and the number of assembly steps can be reduced and the cost can be reduced. it can. However, this causes the following problems when the top plate is made of steel plate. That is, in the case of a steel plate top plate, the bottom surface is subjected to a surface treatment for rust prevention, so if an impact is applied to the top plate by vigorously placing a pan on the virtues on the top plate, the surface treatment The bottom surface of the top plate may be scratched at the contact portion of the fixing portion, and the bottom surface of the top plate may be rusted.

JP-A-6-50557

  In view of the above, an object of the present invention is to provide a stove that can prevent the bottom surface of the top plate from being scratched by a fixing portion of a plate-like component and rusting.

  In order to solve the above-mentioned problems, the present invention is formed on a stove main body, a steel plate top plate that covers the stove main body from above, and has surface treatment for rust prevention on the upper and lower surfaces, and an upper edge of the stove main body. A stove including a plate-like component having a fixing portion sandwiched between the flange portion and the top plate, the plate spring portion being formed in the fixing portion of the plate-like component, and being fixed by the elastic force of the plate spring portion The portion is elastically sandwiched between the flange portion and the top plate.

  According to the present invention, even if an impact is applied to the top plate, the impact is absorbed by the bending of the leaf spring portion formed in the fixed portion. Therefore, it is possible to prevent the bottom surface of the top plate subjected to the surface treatment from being scratched at the contact portion of the fixing portion, and it is possible to effectively prevent the rust generation on the bottom surface of the top plate.

  It is also possible to form the leaf spring portion so as to abut the lower surface of the top plate. However, in this case, the end portion of the leaf spring portion that abuts the lower surface of the top plate is deformed by the bending of the leaf spring portion. It may move by rubbing the lower surface, and scratches may be made on the lower surface of the top plate. Therefore, it is desirable that the leaf spring portion is formed so as to contact the upper surface of the flange portion of the stove body. However, if the leaf spring part is formed in this way, the bending part acts on the fixed part due to the bending of the leaf spring part, causing a slight but warping of the fixed part, so that the upper surface of the fixed part is on the lower surface of the top plate. It comes in line contact, and the certainty of preventing scratches on the lower surface of the top plate is lowered.

  Therefore, it is desirable to form a convex portion having a flat upper end surface in contact with the lower surface of the top plate on the upper surface of the fixed portion. According to this, even if a bending moment is applied to the fixed portion due to the bending of the leaf spring portion, the convex portion is highly rigid and thus does not warp, and the upper end surface of the convex portion is in surface contact with the lower surface of the top plate. Maintained in a state. Therefore, the bottom surface of the top plate can be reliably prevented from being damaged.

  In addition, in a stove provided with a battery case and a case support plate for supporting the battery case in the stove body, a drip-proof covering the battery case from above to prevent dripping of the battery case. A cover may be provided. In this case, if the plate-shaped part is a drip-proof cover, the screwing operation of the drip-proof cover to the stove body is not necessary. Furthermore, if the drip-proof cover is formed with a pressing portion that extends downward to cover the side surface of the battery case and presses the case support plate from above, the case support plate can be pressed so as not to move up and down. Therefore, the case support plate can be positioned and fixed in the stove body simply by engaging the case support plate with the stove body so as not to move in the horizontal direction, which is advantageous in reducing the number of assembly steps and reducing costs.

The perspective view which shows the engaging part of the case support plate of the stove of embodiment, and a stove main body front board part.

  FIG. 1 shows a stove according to an embodiment of the present invention. This stove has a stove body 1, a top plate 2 that covers the stove body 1 from above, and a pair of left and right exposed on the top plate 2 through burner openings (not shown) provided at two left and right sides of the top plate 2. Burners 3 and 3, a pair of left and right virtues 4 and 4 placed so as to surround the burner 3 on the top plate 2, a grill 5 provided at the lateral center of the stove body 1, and the stove body 1 And a battery case 6 provided on one side portion in the lateral direction.

  The top plate 2 is formed of a plated steel plate that has been subjected to surface treatment for rust prevention on both the upper and lower surfaces, for example, hot dip aluminum alloy plating. In addition, you may perform a fluorine process in order to improve the cleaning property on the upper surface of the top plate 2 which consists of a plated steel plate. Moreover, it is also possible to form the top plate 2 with the steel plate which gave the wrinkle process to upper and lower surfaces.

  As shown in FIG. 3, the battery case 6 includes a case main body 61 for storing a battery, with a cover plate 61 a attached to the front end, and a box 62 for storing the case main body 61 so that the case main body 61 can be pulled out forward. A case support plate 7 is installed on one side of the stove main body 1, and the battery case 6 is supported by the case support plate 7.

  In order to prevent boiled spilled from the burner opening from dropping on the opening 62a formed on the upper surface of the box 62 through the lower surface of the top plate 2, as shown in FIGS. A drip-proof cover 8 is provided as a plate-like component that covers the case 6 from above. A rising portion 81 is formed at the front end and the lateral outer edge of the drip-proof cover 8. And the fixing | fixed part 82 bent outward is formed in the upper end of the rising part 81 of an outer edge, and the flange part 11 and top plate which formed this fixing | fixed part 82 in the upper edge of the side plate part of the one side of the stove main body 1 Between the two and fixed.

  2 to 5, a claw portion 821 that is bent downward is formed on the outer edge of the fixing portion 82, and the claw portion 821 is inserted into the engagement hole 111 formed in the flange portion 11. Positioning. The fixed portion 82 is formed with leaf spring portions 822 and 822 at both the front and rear ends that abut against the upper surface of the flange portion 11. Further, a convex portion 823 having a flat upper end surface that contacts the lower surface of the top plate 2 is formed on the upper surface of the fixed portion 82.

  If the fixing portion 82 is sandwiched between the flange portion 11 and the top plate 2 in this manner, the drip-proof cover 8 can be fixed without requiring a troublesome screwing operation, and the cost can be reduced. However, if the fixing portion 82 is simply sandwiched between the flange portion 11 and the top plate 2, when a shock is applied to the top plate 2 by vigorously placing a pan on the virtues 4 on the top plate 2, The bottom surface of the top plate 2 subjected to the surface treatment is scratched at the contact portion of the fixing portion 82, and rust is generated on the bottom surface of the top plate 2.

  On the other hand, in the present embodiment, since the plate spring portion 822 is formed in the fixed portion 82, the fixed portion 82 is elastically formed between the flange portion 11 and the top plate 2 by the elastic force of the plate spring portion 822. Even if it is sandwiched and an impact is applied to the top plate 2, the impact is absorbed by the bending of the leaf spring portion 822. Therefore, it is possible to prevent the bottom surface of the top plate 2 subjected to the surface treatment from being scratched at the contact portion of the fixing portion 82, and to prevent rust from being generated on the bottom surface of the top plate 2.

  Although it is conceivable to form the leaf spring portion 822 so as to contact the lower surface of the top plate 2, in this case, the end portion of the leaf spring portion 822 that contacts the lower surface of the top plate 2 is bent by the leaf spring portion 822. Accordingly, there is a possibility that the lower surface of the top plate 2 moves while being rubbed, and the lower surface of the top plate 2 is scratched. Therefore, in the present embodiment, the leaf spring portion 822 is formed so as to contact the upper surface of the flange portion 11.

  Further, when the upper surface of the fixing portion 82 is formed flat, the upper surface of the fixing portion 82 is warped due to a bending moment acting on both front and rear ends of the fixing portion 82 as the leaf spring portion 822 is bent. As a result, the upper surface of the fixing portion 82 comes into line contact with the lower surface of the top plate 2, and the certainty of preventing damage to the lower surface of the top plate is reduced.

  Therefore, in the present embodiment, the convex portion 823 is formed on the upper surface of the fixed portion 82 as described above. According to this, even if a bending moment acts on the fixed portion 82 due to the bending of the leaf spring portion 822, the convex portion 823 is highly rigid and thus does not warp, and the upper end surface of the convex portion 823 is the top plate 2 of the top plate 2. The surface is kept in surface contact with the lower surface. Therefore, it is possible to reliably prevent the bottom surface of the top plate 2 from being damaged.

  Further, in the present embodiment, a protruding portion 83 that is bent forward from the upper end of the rising portion 81 at the front end of the drip-proof cover 8 is formed. Referring to FIGS. 3 and 6, a claw portion 831 that is bent downward is formed at the front end of the overhang portion 83, and this claw portion 831 is attached to the flange portion 12 at the upper edge of the front plate portion of the stove body 1. It is inserted into the formed engagement hole 121 and positioned.

  Further, a protruding portion 832 having a flat upper end surface is formed on the upper surface of the portion of the overhanging portion 83 that is disengaged from the flange portion 12, and the lower surface of the top plate 2 is brought into contact with the upper end surface of the protruding portion 832, thereby Can be pressed from above. In addition, although the leaf | plate spring part is not formed in the overhang | projection part 83, since the convex part 832 is formed in the part remove | deviated from the flange part 12, even if an impact is applied to the top plate 2, the overhang | projection part 83 itself No impact is caused by this bending, and the lower surface of the top plate 2 is not damaged.

  In addition, a pressing portion 84 extending downward is formed at the lateral inner edge of the drip-proof cover 8 so as to cover the side surface of the battery case 6. Then, as shown in FIG. 3, a bowl-shaped receiving portion 71 is formed on the lateral inner edge of the case supporting plate 7, and the lower edge of the pressing portion 84 is brought into contact with the receiving portion 71, so that the case supporting plate 7 is Pressing from above. The pressing portion 84 also functions as a heat shield plate that prevents heat from the grill 5 from reaching the battery case 6.

  A claw portion 85 is provided at the rear end of the drip-proof cover 8 and is inserted into an engagement hole 131 formed in the front surface of the burner support frame 13 provided horizontally in the stove body 1. The reaction force from the pressing portion 84 acting on the inner edge of the drip-proof cover 8 can be received by the burner support frame 13 via the claw portion 85.

  Leg piece portions 72 and 73 seated on the bottom of the stove main body 1 are suspended from the front portion of the lateral inner edge and the intermediate portion of the lateral outer edge of the case support plate 7. At the lower end of the leg piece 72 at the inner edge, an engagement portion 721 is formed that engages with the claw portion 14 cut and raised at the bottom of the stove body 1 from the rear. Thereby, the position shift of the case support plate 7 to the front is prevented.

Further, at the front end of the case support plate 7, a projecting portion 74 is provided so as to be seated on the lower edge of the opening 15 for the battery case 6 opened in the front plate portion of the stove body 1. Then, as shown in FIG. 7, a claw portion 741 to be inserted into an engagement hole 151 formed at the lower edge of the opening 15 is formed on the overhang portion 74 so that the case support plate 7 is displaced rearward and laterally. I try not to.

  Here, in the present embodiment, the case support plate 7 can be pressed by the pressing portion 84 formed on the drip-proof cover 8 so as not to move up and down. Therefore, the case support plate 7 can be positioned and fixed in the stove body 1 simply by engaging the case support plate 7 with the stove body 1 so as not to move in the horizontal direction at the engaging portion 721 or the claw portion 741.

  In addition, in this embodiment, since it is only the receiving part 71 formed in the horizontal direction inner edge of the case support plate 7 that the press part 84 presses, there is a possibility that the case support plate 7 may be inclined inward in the horizontal direction. is there. Therefore, a tongue piece 16 that contacts the lower surface of the outer edge of the case support plate 7 is cut out on the side plate of the stove body 1, and the outer edge of the case support plate 7 is screwed into the tongue piece 16 from above. Fastening at 75 prevents the case support plate 7 from tilting. Even if screwing is performed in this way, only one screwing point is required, so that the number of assembling steps can be reduced and the cost can be reduced.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, a pair of pressing portions can be formed on the drip-proof cover 8 so as to press both side edges of the case support plate 7 in the lateral direction. This eliminates the need for screwing the case support plate 7 at all. Moreover, although the said embodiment applies this invention to the stove provided with the drip-proof cover 8, the drip-proof cover 8 which has a fixing part pinched | interposed between the flange part of the upper edge of a stove main body, and a top plate. The present invention can be similarly applied to a stove including other plate-like components. Moreover, although the stove of the said embodiment is a thing with the grill 5, this invention is applicable similarly to the stove without a grill.
