  Preferred examples of the present invention are shown below. The invention is not limited to the following examples.

  In the gas stove of the first aspect, the annular frame may be disposed along the opening and adhered to the opening through an adhesive medium.

  In this gas stove, since the adhesive medium is interposed between the annular frame portion of the inner frame and the opening formed in the plate-like structure, the inner frame can be fixed more firmly in the vicinity of the opening. In addition, a gap does not easily occur between the inner frame and the plate-like structure.

  In the gas stove of the first aspect, the annular frame portion may be provided with a grooved storage portion opened to the opening side. Then, the annular frame may be adhered to the opening through an adhesive medium stored between the storage and the opening.

  The gas stove can store more adhesive medium in the storage section, and the stored adhesive medium can more firmly bond the annular frame and the opening of the inner frame.

  The gas stove of the first aspect may have an elastic member fixed to the back surface side of the top plate main body. The elastic member may be configured to apply a pressing force to a part of the inner frame and bias the storage portion toward the opening.

  In this gas stove, the storage portion is biased toward the opening by the elastic member fixed to the back surface side of the top plate main body, so it is difficult to apply a strong force to separate the storage portion from the opening. Poor adhesion between the and the opening is less likely to occur. Therefore, the function of adhering with more adhesive medium stored in the storage part and the function of biasing the storage part to the opening side to prevent adhesion failure act synergistically, and further stronger adhesion To be realized.

  In the gas stove of the first aspect, the elastic member may be bonded to the back surface of the top plate main body by a quick-drying adhesive whose drying speed is faster than the bonding medium.

  This gas stove can be made to act to urge the annular frame downward by the elastic member fixed more quickly, and even if the drying of the adhesive medium is insufficient, it is caused by the elastic member The biasing force makes it easy to maintain the state in which the annular frame of the inner frame is pressed against the opening.

  The annular frame part may be provided with the groove-shaped storage part open | released at the opening part side regarding the manufacturing method of the gas stove of a 2nd aspect. The disposing step may be a step of disposing the annular frame along the opening with the adhesive medium interposed between the reservoir and the opening.

  In this manufacturing method, the annular frame and the opening can be adhered using more adhesive medium stored in the storage, and the inner frame and the plate-like structure can be adhered more firmly.

  In the method of manufacturing the gas stove according to the second aspect, the elastic member is disposed on the back surface side of the top plate main body, and the elastic force is applied in a state of applying a pressing force to a part of the inner frame and urging the storage part toward the opening You may include the fixing process of fixing a member to a top-plate main-body part.

  In this manufacturing method, since the elastic member can be fixed so as to apply a pressing force to a part of the inner frame and bias the storage portion toward the opening, a state in which the storage and the opening are difficult to separate The bonding medium can be interposed between them to hold the state. Therefore, the outflow of the adhesive medium can be suppressed, and the vicinity of the reservoir and the opening can be fixed more firmly. In particular, since the elastic member is configured to be fixed to the back surface side of the top plate main body, such an elastic member does not easily appear on the surface of the top plate main body, and the appearance is attributable to the appearance on the top plate main body It is possible to suppress the decline.

  In the method for producing a gas stove according to the second aspect, the fixing step may be a step of bonding the elastic member to the back surface of the top plate main body with a quick-drying adhesive whose drying speed is faster than the bonding medium.

  In this manufacturing method, it becomes easy to dry the adhesive between the elastic member and the top plate main body before the adhesive medium present between the reservoir and the opening is dried. Therefore, even if the adhesive medium existing between the storage portion and the opening portion is not sufficiently dried, the elastic member fixed to the top plate main body acts to bias the annular frame downward. In such a case, the adhesive medium is likely to flow out of the reservoir and to cause adhesion failure.

(Manufacturing process of top plate)
The manufacturing process of the top plate 30 will be described. FIGS. 17 and 18 are explanatory views schematically illustrating the manufacturing process of the top plate portion 30 of the first embodiment. As shown in FIG. 17 (A), the outer frame 50 is prepared, and is turned upside down. In the following description, as in the case of the gas stove 1 described above, the direction orthogonal to the mounting surface when the gas stove 1 is mounted on a flat mounting surface is the vertical direction. The side where the apparatus main body 1A is positioned with respect to the top plate portion 30 is a lower side, and the side opposite to the lower side is an upper side. The left-right direction and the front-rear direction are also the same as the description of the gas stove 1 described above.

  As shown in FIG. 17B, the inner frame 40 (more specifically, the annular frame 41) is disposed along the opening 35A of the plate-like structure 35. The bottom wall 41D, the lower inner wall 41E, the flange 41F, and the extension 45 are inserted into the inside of the opening 35A, and the extension 45 is inserted between the upper wall 52B and the lower wall 52C. The rear end portion extending in the width direction (left and right direction) of the outer wall portion 41B is brought into contact with the upper wall portion 52B from the front side, and the first extension portion 46 is brought into contact with the upper wall portion 52B from the lower side. The second extending portion 47 is brought into contact with the projecting portion 52E from the front side, and alignment in the front-rear direction of the second extending portion 47 with respect to the outer frame body 50 is performed. The lower end portion of the second extending portion 47 is brought into contact with the lower wall portion 52C from the upper side.

  The coupling member 61 is assembled so as to be inserted into the through hole 52D and the hole 48A in a state where each of the pair of holes 48A, 48A overlaps with each of the pair of through holes 52D, 52D. Thus, the outer frame 50 and the inner frame 40 are tightened together. By assembling the connecting member 61 to the outer frame 50 and the inner frame 40, alignment in the width direction of the inner frame 40 with respect to the plate-like structure 35 is performed. The process of fastening the outer frame 50 and the inner frame 40 together by the connecting member 61 may correspond to an example of the “connecting process” in the present invention.

  As shown in FIG. 17C, the packing 36 is inserted into the storage section 43. The packing 36 is inserted from below into the front end side portion and the width direction both end side portions of the storage portion 43.

  As shown to FIG. 18A, the top-plate main-body part 31 is assembled | attached with respect to the outer frame 50 and the inner frame 40, and the plate-shaped structure part 35 is formed. The outer peripheral portion of the top panel main body portion 31 is assembled to the outer frame body 50, so that the outer frame body 50 covers the entire outer peripheral portion except the notch portion 34 in the top panel main body portion 31. The cutout portion 34 of the top plate main body portion 31 and the rear end side frame portion 52 of the outer frame body 50 form an opening 35A having a substantially rectangular shape in plan view. The lower end portions on the front side and the left and right sides of the outer wall portion 41B of the inner frame body 40 are in contact with the surface of the top panel main body portion 31. The opening 35 </ b> A is located on the open side of the reservoir 43.

  As shown in FIG. 18B, the adhesive medium 71 is poured between the reservoir 43 and the opening 35A (more specifically, the side end 31A). The adhesive medium 71 is stored between the inner surface of the storage section 43 and the opening section 35A in a state where the opening section 35A is positioned on the open side of the storage section 43. The adhesive medium 71 is stored in a space surrounded by the side end 31A, the packing 36, and the notch 34 of the top plate main body 31. The step of interposing the bonding medium 71 between the annular frame 41 and the opening 35A and arranging the annular frame 41 along the opening 35A may correspond to an example of the "arranging step" in the present invention.

  As shown in FIG. 18C, in a state where the adhesive 72 is stored in the storage portion 37B of the elastic member 37, the second plate portion 37E of the bending portion 37C is inserted between the bottom wall portion 41D and the flange portion 41F. The upper surface portion of the main body portion 37A is the top plate main body in a state where the bending portion 37C is elastically deformed so as to bend upward (side toward the top plate main body portion 31) by applying a pressing force to the flange portion 41F. The back surface of the part 31 is brought into contact. The elastic member 37 is adhered to the top plate main body 31 via an adhesive 72 stored between the reservoir 37 B and the back surface of the top plate main body 31. For fixing the elastic member 37 to the top plate main body 31, a quick-drying adhesive 72 whose drying speed is faster than that of the adhesive medium 71 is used. Since the elastic member 37 applies a pressing force to the collar portion 41F of the inner frame and biases the annular frame portion 41 downward, the open side of the storage portion 37B is pressed against the side end 31A. . The elastic member 37 is disposed on the back surface side of the top plate main body portion 31 and in a state in which a pressing force is applied to a part of the inner frame body 40 and the annular frame portion 41 is biased downward The process of fixing to the part 31 may correspond to an example of the “fixing process” of the present invention.

Hereinafter, the effects of the present configuration will be illustrated.
In the gas stove 1 of this configuration, an opening 35A is formed in a partial range in the width direction on the rear end side and the widthwise center side of the plate-like structure 35, and the inner frame 40 is formed while an exhaust port 40A is formed. It is the structure provided with the annular frame part 41 arrange | positioned along the part 35A. As described above, since the inner frame 40 is assembled in a partial range in the width direction on the rear end side of the plate-like structure 35, the inner frame is assembled compared to the entire range in the width direction of the plate-like structure 35. The presence of the inner frame 40 can be reduced, and the decrease in the aesthetic appearance due to the presence of the inner frame 40 being too large can be suppressed. Moreover, since the extension 45 of the inner frame 40 and the rear end side frame 52 of the outer frame 50 are connected to each other by the connecting member 61 and the connecting member 61 performs positioning in the width direction, The inner frame 40 can be fixed more accurately and more stably at the predetermined position (the position aligned by the connecting member 61) of the plate-like structure 35 including the outer frame 50.

  The annular frame 41 is disposed along the opening 35 A and is bonded to the opening 35 A via the adhesive medium 71. Therefore, since the adhesive medium 71 intervenes between the annular frame portion 41 of the inner frame 40 and the opening 35A formed in the plate-like structure 35, the inner frame 40 can be made stronger near the opening 35A. It can be fixed. In addition, a gap does not easily occur between the inner frame 40 and the plate-like structure 35.

  The annular frame portion 41 includes a grooved storage portion 43 opened to the opening 35A side. The annular frame 41 is bonded to the opening 35A via the adhesive medium 71 stored between the storage 43 and the opening 35A. Therefore, a large amount of adhesive medium 71 can be stored in the storage portion 43, and the annular frame portion 41 of the inner frame 40 and the opening 35A can be more firmly bonded by the stored adhesive medium 71.

  The gas stove 1 has an elastic member 37 fixed to the back surface side of the top plate main body 31. The elastic member 73 applies a pressing force to a part of the inner frame 40 and biases the storage portion 43 toward the opening 35A.

  Therefore, the reservoir 43 is urged toward the opening 35A by the elastic member 37 fixed on the back surface side of the top plate main body 31, so a strong force is applied to separate the reservoir 43 from the opening 35A. This becomes difficult, and adhesion failure between the reservoir 43 and the opening 35A is less likely to occur. Therefore, the function of adhering with more adhesive medium 71 stored in the storage part 43 and the function of biasing the storage part 43 to the opening 35A side to prevent adhesion failure act synergistically, and further more Strong adhesion is realized.

  The elastic member 37 is bonded to the back surface of the top plate main body 31 by a quick-drying adhesive 72 whose drying speed is faster than that of the bonding medium 71.

  For this reason, the elastic member 37 fixed earlier can act to urge the annular frame portion 41 downward, and the elastic member 37 may be formed even if the drying of the adhesive medium 71 is insufficient. The state in which the annular frame portion 41 of the inner frame body 40 is pressed against the opening 35A is likely to be maintained by the biasing force resulting from this.

  The manufacturing method of the gas stove 1 of this configuration can obtain the same effects as the effects of the gas stove 1 described above. Furthermore, in this manufacturing method, since the adhesive medium 71 is interposed between the annular frame 41 of the inner frame 40 and the opening 35A and the annular frame 41 is disposed along the opening 35A, the intervening adhesive medium When 71 is dried, the annular frame 41 of the inner frame 40 can be firmly fixed to the opening 35A. In addition, since the adhesive medium 71 can be dried in a state in which the extending portion 45 and the rear end side frame portion 52 are connected to each other by the connecting member 61 and aligned in the width direction by the connecting member 61, more accurately The adhesive medium 71 can be dried in the positioned state, and the annular frame 41 is less likely to be displaced relative to the opening 35A during the period until the drying is completed.

  The annular frame portion 41 includes a grooved storage portion 43 opened to the opening 35A side. In the method of manufacturing the gas stove 1 of this configuration, the disposing step includes the step of disposing the annular frame portion 41 along the opening 35A in a state where the adhesive medium 71 is interposed between the reservoir 43 and the opening 35A. . In this manufacturing method, the annular frame 41 and the opening 35A can be adhered using more adhesive medium 71 stored in the storage 43, and the inner frame 40 and the plate-like structure 35 are more firmly adhered. can do.

  In the method of manufacturing the gas stove 1 of this configuration, the elastic member 37 is disposed on the back surface side of the top plate main body portion 31, a state in which pressing force is applied to a part of the inner frame 40, and the annular frame portion 41 is biased downward. The process of fixing the elastic member 37 to the top-plate main-body part 31 in the state to be carried out is included. Therefore, since the elastic member 37 applies a pressing force to a part of the inner frame 40 and biases the annular frame portion 41 downward, the opening side of the storage portion 43 corresponds to the surface of the opening 35A. You can hold it down. Therefore, the open side of the reservoir 43 is reliably blocked by the surface of the opening 35A, and the adhesive medium 71 can be prevented from flowing out of the reservoir 43. In particular, since the elastic member 37 is configured to be fixed to the back surface side of the top plate main body 31, such elastic member 37 does not easily appear on the surface of the top plate main body 31, and can be seen on the top plate main body 31 You can control the decline in aesthetics caused by

  The method of manufacturing the gas stove 1 of the present configuration includes a step of bonding the elastic member 37 to the back surface of the top plate main body portion 31 with the quick-drying adhesive 72 whose drying speed is faster than the bonding medium 71. Therefore, the adhesive 72 between the elastic member 37 and the top plate main body 31 can be easily dried before the adhesive medium 71 existing between the reservoir 43 and the opening 35A is dried. Therefore, even if the adhesive medium 71 existing between the reservoir 43 and the opening 35A is not sufficiently dried, the annular frame 41 is urged downward by the elastic member 37 fixed to the top plate main body 31. The adhesive medium 71 is likely to flow out of the reservoir 43 and cause an adhesive failure.
