Description

  The present invention comprises a stove body and a top plate that covers the stove body from above, an outer bent flange is formed on the upper edge of the peripheral wall portion of the stove body, and the stove body is dropped into the stove opening established in the countertop The drop-in type stove is configured such that the outer bending flange is hooked on the mouth edge of the stove opening and the stove body is suspended from the counter top.

  The size of the stove opening to be opened at the counter top varies, and the type of drop-in stove that can be selected when replacing the stove is limited by the size of the stove opening. In this case, the stove body is made relatively small so that it can be dropped into a small stove opening, and the outer bending flange on the upper edge of the stove body is formed wide so that it can be hooked to the mouth edge even with a large stove opening. If it does, it can correspond to the stove opening of various sizes. However, when such a stove body is dropped into a relatively large stove opening, there is a large gap between the peripheral wall portion of the stove body and the inner wall surface of the stove opening, and the stove body can be greatly displaced within the stove opening. There is sex.

  Here, conventionally, in order to prevent displacement of the stove body, a fixing bolt is screwed into the peripheral wall portion of the stove body from the inside of the stove body, and the tip of the bolt comes into contact with the inner wall surface of the stove opening. It is known to fix the stove body in the stove opening by screwing into the stove. However, when the protruding length of the fixing bolt from the peripheral wall portion of the stove body is increased, the bolt is easily inclined by the contact reaction force when the tip of the fixing bolt comes into contact with the inner wall surface of the stove opening. For this reason, when the distance between the peripheral wall portion of the stove body and the inner wall surface of the stove opening exceeds a predetermined limit, it becomes difficult to firmly fix the stove body with the fixing bolt.

  Therefore, conventionally, Patent Document 1 also discloses that a spacer is interposed between the tip of a fixing bolt screwed into the peripheral wall portion of the stove body and the inner wall surface of the stove opening. In this case, when the fixing bolt is screwed in, the spacer is pushed toward the inner wall surface of the stove opening by the fixing bolt, and finally the fixing bolt comes into contact with the inner wall surface of the stove opening via the spacer. Therefore, the protrusion length of the fixing bolt from the peripheral wall portion of the stove body is shortened by the amount of the spacer. As a result, even if the interval between the peripheral wall portion of the stove body and the inner wall surface of the stove opening becomes long, the stove body can be firmly fixed without causing the inclination of the fixing bolt.

  By the way, recently, in order to prevent the user from removing the top board and tampering with the equipment in the stove body, the top board is fixed to the stove body so that the user cannot remove the top board. A drop-in stove is now available on the market. In such a drop-in type stove, the fixing bolt screwed into the peripheral wall portion of the stove body cannot be operated, and the stove body cannot be fixed.

JP 2006-125595 A

  In view of the above points, the present invention has been proposed in which the top plate is fixed to the stove body, and the stove body even if the interval between the inner wall surface of the stove opening established in the countertop and the peripheral wall portion of the stove body becomes long The challenge is to provide a drop-in stove that can be securely fixed.

  In order to solve the above-mentioned problems, the present invention comprises a stove body and a top plate that covers the stove body from above, an outer bent flange is formed on the upper edge of the peripheral wall of the stove body, and the stove body serves as a countertop. It is a drop-in type stove where the outer bending flange is hooked on the mouth edge of the stove opening while being dropped into the opened stove opening, and the stove body is suspended from the counter top. In the screw hole formed in the outer end of the spacer opposite to the inner end of the spacer that contacts the outer surface of the peripheral wall of the stove body and the spacer that contacts the outer surface of the peripheral wall of the stove main body And a fixing bolt that is screwed in from the outside. The stove body is fixed in the stove opening by bringing the head of the fixing bolt into contact with the inner wall surface of the stove opening.

  According to the present invention, since the fixing bolt is screwed into the screw hole at the outer end portion of the spacer from the outside, the fixing bolt is operated from below the counter top so that its head is placed inside the stove opening. It can be brought into contact with the wall surface. Therefore, even if the top plate is fixed to the stove body and the interval between the peripheral wall portion of the stove body and the inner wall surface of the stove opening becomes long, the stove body can be firmly fixed.

  Further, in the present invention, a convex portion that bulges outward is formed on the peripheral wall portion of the stove body, an engagement hole is formed in the outer bending flange, and the convex portion is engaged with the inner end portion of the spacer. It is desirable that a concave portion to be joined is formed, and a claw portion inserted and locked from below into the engagement hole is formed at the upper end of the outer end portion of the spacer. According to this, by pushing up the inner end portion of the spacer while the claw portion is inserted and locked in the engagement hole, the concave portion of the inner end portion is engaged with the convex portion of the peripheral wall portion of the stove body, and the spacer is It will be temporarily fixed to the stove body in a self-supporting state. Therefore, the fixing bolt can be operated without manually pressing the spacer, and workability is improved.

  In addition, the convex part of the peripheral wall part of the stove body is such that when the stove body is dropped into a stove opening of approximately the same size as this, the peripheral wall part comes into surface contact with the inner wall surface of the stove opening and the amount of heat transfer to the counter top is reduced. Conventionally, it is provided to prevent the increase. The above-described structure in which the spacer is temporarily fixed using such a convex portion is very reasonable.

The top view of the drop-in type stove of embodiment of this invention. The top view of the stove main body of the drop-in type stove of embodiment. (A) Sectional drawing of the principal part which shows the state which fixed the stove body of the drop-in type stove of embodiment using a spacer, (b) Sectional drawing of the principal part which shows the state which fixed the stove body without using a spacer . The perspective view of a spacer.

  FIG. 1 shows a state in which a drop-in stove is incorporated in the countertop 1 of the system kitchen. This drop-in stove includes a box-shaped stove body 2 (see FIG. 3) having an open upper surface, a top plate 3 that covers the stove body 2 from above, and two left and right burners 4.

  An outer bending flange 21 is formed on the upper edge of the peripheral wall portion of the stove body 2. Then, with the stove body 2 dropped into the stove opening 11 opened in the countertop 1, the outer bending flange 21 is hooked on the mouth edge of the stove opening 11, and the stove body 2 is suspended from the countertop 1. ing.

  As shown in FIG. 3, the top plate 3 includes a top plate main body 31 formed of heat-resistant glass or a thick metal plate, and a packing 32 attached to the peripheral portions of the openings opened at two left and right sides of the top plate main body 31. It consists of two left and right juice trays 33 placed on the packing 32 so as to cover the opening. A burner opening 33a is formed at the center of each soup pan 33, and the upper end of the mixing tube 41 of each burner 4 installed in the stove body 2 is inserted into the burner opening 33a. Each burner 4 includes a burner body 42 that is larger in diameter than the burner opening 33 a and is exposed on the juice receiving tray 33. A cylindrical portion 43 that is suspended from the center of the lower surface of the burner body 42 is provided at the upper end of the mixing tube 41. It is fitted. In addition, on each juice receiving tray 33, five virtues 5 each having a plurality of five virtue claws 52 attached to an annular five virtue frame 51 are placed so as to surround the burner body 42. Furthermore, the left and right operation knobs 6 for the burner 4 are provided on the front portion of the top plate body 31.

  Each soup pan 33 is fastened to the upper end of the fixed piece 22 erected on the bottom of the stove main body 2 with a screw 34 in a projection plane below the burner main body 42. Thereby, the top plate 3 is fixed to the stove body 2. Moreover, since the screw 34 is blindfolded by the burner main body 42, the top plate 3 cannot be removed easily. The top plate 3 is fixed to the stove body 2 at the shipping stage, and the stove body 2 is dropped into the stove opening 11 with the top plate 3 attached.

  By the way, the size of the stove opening 11 varies in size. Therefore, the stove body 2 is formed in a size that can be inserted into a small stove opening, while the left and right side and rear outer flanges 21 are hooked on the mouth edge of the large stove opening as shown in FIG. It is formed so as to be wide so that it can accommodate various types of small and large stove openings 11. The stove body 2 is dropped into the stove opening 11 so that the peripheral wall portion on the front side is close to the inner wall surface on the front side of the stove opening 11 regardless of the size of the stove opening 11. Therefore, the front outer bending flange 21 is formed narrow.

  A pair of front and rear screw holes 23 are formed in the peripheral wall portions on the left and right sides of the stove body 2, and a pair of front and rear projections 24 bulge outwardly at positions shifted from the screw holes 23 in the front and rear direction. Is formed. When the stove body 2 is dropped into the stove opening 11 having substantially the same size as the convex portion 24, the peripheral wall portion comes into surface contact with the inner wall surface of the stove opening 11 and the amount of heat transfer to the counter top 1 increases. In order to prevent this, it is provided conventionally.

  When the size of the stove opening 11 is relatively small, the fixing bolt 7 is screwed into the screw hole 23 in the peripheral wall portion of the stove body 2 from the outside. Then, after dropping the stove body 2 into the stove opening 11, the installer enters the lower part of the countertop 1 and operates the fixing bolt 7, and as shown in FIG. 3B, the head 71 of the fixing bolt 7. Is brought into contact with the inner wall surface of the stove opening 11. According to this, even if the top plate 3 is fixed to the stove body 2 and the fixing bolt 7 cannot be operated from above, the stove body 2 can be fixed in the stove opening 11.

  Here, when the stove opening 11 is large and the distance between the peripheral wall portion of the stove body 2 and the inner wall surface of the stove opening 11 becomes long, it is conceivable to fix the stove body 2 using a long bolt. However, when the bolt protruding length from the peripheral wall portion of the stove main body 2 increases, the bolt easily tilts due to the contact reaction force when the bolt head contacts the inner wall surface of the stove opening. For this reason, when the distance between the peripheral wall portion of the stove body 2 and the inner wall surface of the stove opening 11 exceeds a predetermined limit (for example, 50 mm or more), it is difficult to firmly fix the stove body 2 with the fixing bolt 7.

  Therefore, when the stove opening 11 is large, the stove body 2 is fixed using a pair of front and rear spacers 8 that abut on the outer surfaces of the peripheral wall portions on the left and right sides of the stove body 2. As shown in FIGS. 3A and 4, each spacer 8 is made of sheet metal and has a box shape that opens upward. A concave portion 81 that engages with the convex portion 24 of the peripheral wall portion of the stove body 2 is formed at the inner end portion of the spacer 8 that contacts the peripheral wall portion of the stove body 2. Further, at the outer end opposite to the inner end of the spacer 8, a central screw hole 82 and a pair of front and rear projections 83 that prevent the outer end from making surface contact with the inner wall surface of the stove opening 11. Further, a pair of claw portions 84 bent outward are formed at the upper end of the outer end portion. In addition, square engagement holes 25 corresponding to the claw portions 84 of the spacers 8 are formed in the outer bending flanges 21 on the left and right sides of the stove body 2. Then, when the inner end portion of the spacer 8 is pushed upward while the claw portion 84 of the spacer 8 is inserted and locked into the engagement hole 25 from below, the concave portion 81 of the inner end portion of the spacer 8 is formed on the stove body 2. It engages with the convex portion 24 of the peripheral wall portion. Thereby, the spacer 8 is temporarily fixed to the stove body 2 in a state where the spacer 8 is self-supporting.

  At the time of stove installation, after the stove body 2 is dropped into the stove opening 11, the installer sinks under the counter top and the fixing bolt 7 is screwed into the screw hole 82 so that the spacer 8 is inserted as described above. Temporarily fix to. Next, the fixing bolt 7 is operated from below the counter top 1, and the head 71 of the fixing bolt 7 is brought into contact with the inner wall surface of the stove opening 11 as shown in FIG.

  By using the spacer 8 in this way, the stove body 2 can be firmly fixed without causing the fixing bolt 7 to be inclined even if the distance between the peripheral wall portion of the stove body 2 and the inner wall surface of the stove opening 11 is increased. . Since the fixing bolt 7 is screwed into the screw hole 82 at the outer end portion of the spacer 8 from the outside, the fixing bolt 7 is fixed from below the counter top 1 even if the top plate 3 is fixed to the stove body 2. The stove body 2 can be fixed by operating the bolt 7. Furthermore, since the spacer 8 is temporarily fixed to the stove main body 2 in a self-supporting state, the fixing bolt 7 can be operated without pressing the spacer 8 by hand, and workability is improved. Further, when the head 71 of the fixing bolt 7 contacts the inner wall surface of the stove opening 11, the spacer 8 is pressed against the peripheral wall portion of the stove body 2 by the contact reaction force, and the stove body 1 is fixed securely.

  In the present embodiment, the spacer 8 is temporarily fixed by engaging the concave portion 81 of the spacer 8 with the convex portion 24 of the stove main body 2 provided to suppress heat transfer to the countertop 1. It is very reasonable.

  By the way, in the said embodiment, although the screw hole 82 was formed in the up-down direction center part of the outer end part of the spacer 8, the position of the screw hole 82 is shifted upwards and the height shown by a virtual line in FIG. The fixing bolts 7 may be provided on the. According to this, even if the countertop 1 is thin, it can be dealt with advantageously.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to this. For example, in the above embodiment, the end surface of the head 71 of the fixing bolt 7 is a flat surface, but the head end surface may be formed in a convex surface such as a conical shape. According to this, the head end face bites into the inner wall surface of the stove opening 11, and the stove body 2 is more firmly fixed.

  Moreover, although the spacer 8 of the said embodiment is a product made from a sheet metal, it is also possible to form a spacer with a die-cast product or a resin block. Furthermore, in the said embodiment, although the spacer 8 is made to contact | abut on the outer surface of the surrounding wall part of the left-right each side of the stove main body 2, it is made to contact the spacer 8 to the outer surface of the surrounding wall part of the front and back each side of the stove body 2. It may be.

  Moreover, although the said embodiment applies this invention to the drop-in type gas stove using the burner 4 as a heat source, this book is similarly applied to the drop-in type electric cooker using an electric heater or an electromagnetic induction coil as a heat source. The invention can be applied.
