Description

  The present invention relates to a top plate of a cooker.

  The top plate of a cooker such as a built-in stove used in the system kitchen is desired to have a flat plate shape with less unevenness from the viewpoint of easy cleaning and aesthetic improvement. On the other hand, in the flat plate shape, it is difficult to ensure the mechanical strength, and it is necessary to devise a technique for preventing the deformation of the top plate due to heat or load. In view of this, a configuration has been proposed in which the top plate has a two-layer structure of an upper plate and a lower plate to improve the strength (see, for example, Patent Document 1).

Japanese Patent Laying-Open No. 2004-360984 (FIG. 1)

However, the two-layer top plate is heavy and inconvenient for installation and transportation. Moreover, the operation | work which fixes an upper board and a lower board to an outer frame is troublesome, and an assembly is complicated.
In view of such a conventional problem, an object of the present invention is to make the assembly lightweight and easy to assemble while ensuring the strength required for the top plate of the cooker.

The top plate of the cooker according to the present invention includes a plate body having a plurality of stove holes, an outer frame member that forms a frame body along an outer edge portion of the plate body, and a longitudinal direction Both ends are fitted into the groove, thereby providing a reinforcing member constructed along a part of the back surface of the plate body.
In the top plate configured as described above, the plate body is supported from the back side by the reinforcing member. Moreover, the weight increase of the whole top plate is suppressed by providing a reinforcement member along a part instead of the whole back surface of a plate main body. Furthermore, the reinforcing member has a simple configuration that is installed on the outer frame member.

In the top plate, the reinforcing member may include a horizontal plate portion that contacts the back surface and a vertical plate portion that protrudes downward from the horizontal plate.
In this case, the presence of the vertical plate portion improves the strength of the reinforcing member with respect to the vertical load.

Further, in the top plate, a plurality of reinforcing members having the same shape may be provided and have a relief recess that avoids the back stove hole.
In this case, since the plurality of reinforcing members are common members, the manufacturing cost is low, and there is no risk of mixing them, so that assembly is easy. Further, the reinforcing member does not interfere with the back stove because of the relief recess.

In the top plate, an elastic sheet may be interposed in the gap between the plate body and the reinforcing member.
In this case, the direct contact between the plate body and the reinforcing member is suppressed by the intervention of the elastic sheet. Therefore, it is possible to suppress the generation of contact sound due to the plate body and the reinforcing member being in direct contact with each other. In addition, variations in the groove width of the outer frame member and the thickness of the reinforcing member can be absorbed by the elastic sheet.

  Moreover, the cooker of this invention may be equipped with the cooker main body, a stove, and any one of said top plates, and there exists said effect as a cooker.

Further, the top plate of the cooking device of the present invention includes a plate main body having a grill exhaust hole and a stove hole from the back to the front, and the grill exhaust hole and the stove along the back surface of the plate main body. A first reinforcing member that extends in the width direction between the holes for use and a second reinforcing member that extends in the width direction in front of the hole for the stove along the back surface of the plate body may be provided. .
In the top plate configured as described above, the plate body is supported from the back side by the first and second reinforcing members. Further, the reinforcing member is placed along the plate main body only in the two front and rear partial areas, and even if the reinforcing member is provided, an increase in weight is suppressed. Furthermore, the structure which only provides a reinforcement member is simple.

In addition, the top plate of the cooking device of the present invention has a plate body having a back stove hole and a front stove hole, from the back to the front, from the back stove hole and from the back stove hole. A reinforcing member that extends in the width direction along the back surface of the plate body may be provided at the back of the front stove hole and at least two locations in front of the front stove hole.
In the top plate configured as described above, the plate body is supported from the back side by the reinforcing member. The place where the reinforcing member is placed along the plate body is only a part of the front and rear two places or the front and rear three places, and even if the reinforcing member is provided, an increase in weight is suppressed. Furthermore, the structure which only provides a reinforcement member is simple.

On the other hand, the method of assembling the top plate of the cooker of the present invention attaches a plate body having a plurality of stove holes to an outer frame member serving as an outer frame, and a reinforcing member longer than the inner method of the outer frame member, Along the back surface of the plate main body, it is applied so as to be inclined with respect to the width direction, and by changing the posture of the reinforcing member in parallel to the width direction from the diagonal, both ends thereof are placed inside the outer frame member. It inserts in the formed groove | channel, It is set as the state constructed by the said outer frame member.
In such a method of assembling the top plate, the reinforcing member is placed in a erected state by being placed in a predetermined position while changing its posture from oblique to parallel. Since the reinforcing member can be easily attached in this way, the top plate can be easily assembled.

According to the top plate of the cooking device of the present invention (or the cooking device of the present invention), since the plate body is supported from the back side by the reinforcing member, the necessary strength against the load can be ensured. Further, by providing the reinforcing member along a part of the plate body instead of the entire back surface, an increase in the weight of the entire top plate can be suppressed and the weight can be reduced. Furthermore, the structure which only constructs a reinforcement member to an outer frame member is simple, and an assembly is easy.
On the other hand, according to the method for assembling the top plate of the present invention, the reinforcing member is placed in a erected state by being placed in a predetermined position while changing its posture from oblique to parallel. Since the reinforcing member can be easily attached in this way, the top plate can be easily assembled.

  FIG. 1 is a perspective view of a built-in cooker 1 used in the system kitchen 100. In the figure, the cooker 1 includes a cooker body 2, a top plate 3 provided on the cooker body 1, one back stove 4, and two near ones (one below the pan), A grill exhaust unit 6 and 7 are provided. The cooker body 2 is provided with a switch 2a and a grill 2b.

  FIG. 2 is an exploded perspective view of each part constituting the top plate 3. The top plate 3 mainly includes a top plate 30 and a middle plate 31 that constitute the plate body 3A, an outer frame member 32 that forms a frame body along the outer edge of the plate body 3A, and a reinforcing member 33 (a pair). Further, it is composed of back plates 35 (4 pieces) and 36 (2 pieces) as retaining members, elastic sheets 37 (14 pieces), and rings 38 and 39 (each quantity is an example). is there.). The elastic sheet 37 is made of, for example, a sponge and is mounted between the top plate 30 and the reinforcing member 33 and between the top plate 30 and the back plate 36, respectively. Direct contact between the top plate 30 and the reinforcing member 33 is suppressed by the interposition of the elastic sheet 37, and generation of contact sound due to direct contact between the top plate 30 and the reinforcing member 33 can be suppressed. In addition, variations in the groove width of the outer frame member 32 and the thickness of the reinforcing member 33 can be absorbed by the elastic sheet 37. The rings 38 and 39 are provided for the protection of the top board 30, prevention of spilling, and positioning of the board 7.

  The top plate 30 is obtained, for example, by applying a glassy coating (enamel) to the surface of a thin steel plate. Further, the top plate 30 is formed with one back stove hole 30a and two front stove holes 30b, and the rings 38 and 39 are respectively attached to the edges of these holes. The middle plate 31 in which the horizontally long grill exhaust hole 31a is formed is formed into a drawn shape by press work in order to ensure strength. The outer frame member 32 is a substantially rectangular frame having an arcuate corner portion, but is originally cut at the center of one side and is connected by caulking plates 34 sandwiched therebetween.

  The reinforcing member 33 is formed by bending a thin steel plate into an angle shape, and includes a horizontal plate portion 33a extending along the back surface of the plate body 3A and a vertical plate portion 33b protruding downward from the horizontal plate portion 33a. In the vicinity of both ends in the longitudinal direction, the vertical plate portion 33b does not exist, but only the horizontal plate portion 33a. Therefore, the vicinity of the both ends is a thin plate. Further, the near side portion in the vicinity of both ends is formed in an arc shape that approximates the curvature of the corner of the outer frame member 32. Due to the presence of the vertical plate portion 33b, the strength of the reinforcing member 33 against a vertical load is improved.

  In addition, an escape recess 33c is formed at the center of the horizontal plate portion 33a so as to avoid the back stove hole 30a when being along the back surface of the plate body 3A. In addition, screw holes 33d (four locations) for fastening together with the ring 39 and screw holes 33e for fastening together with the ring 38 are formed in the horizontal plate portion 33a. The pair of reinforcing members 33 have the same shape and are a common member, so that the manufacturing cost is low, and there is no risk of mixing them, so that assembly is easy.

  FIG. 3 is a plan view of the top plate 3 in a state where components other than the rings 38 and 39 are assembled. The reinforcing member 33 on the back side (upper side in the figure) extends in the width direction between the grill exhaust hole 31a and the back stove hole 30a along the back surface of the plate main body 3A, and also on the near side (lower side in the figure). The reinforcing member 33 on the side) is arranged so as to extend in the width direction from the two front stove holes 30b along the back surface of the plate body 3A. The back reinforcing member 33 is arranged so as to avoid the back stove hole 30a by the escape recess 33c, and thus does not interfere with the back stove 4 (FIG. 1).

  4 (a), 4 (b), and 4 (c) are cross-sectional views taken along lines AA, BB, and CC, respectively, in FIG. 3 (however, only the cross section). (The other side of the cross section is not shown.) FIG. 4 shows a cross section on the right end side of the top plate 3, but the left end side has a similar cross section that is bilaterally symmetrical. In FIG. 4A, grooves 32 a and 32 b and support portions 32 c and 32 d are formed inside the outer frame member 32. The outer frame member 32 forms a frame body with the grooves 32a and 32b along the outer edge portion of the plate body 3A.

  4B, the reinforcing member 33 has one end in the longitudinal direction fitted in the groove 32a with the elastic sheet 37 interposed between the reinforcing member 33 and the top plate 30. The same applies to the other end portion, whereby the reinforcing member 33 is constructed along the back surface of the top plate 30 (plate body 3A). By fitting both end portions of the reinforcing member 33 into the groove 32a, the top plate 30 is held by the outer frame member 32 and is prevented from coming off. Similarly, the reinforcing member 33 on the near side is constructed along the back surface of the top plate 30 (plate body 3A). Further, as shown in FIG. 3, the front-side reinforcing member 33 is fitted not only at both ends in the longitudinal direction but also at the front-side end into the groove (32a) on the lower side of the outer frame member 32. It will be in the state supported by the edge | side (left and right side edge and lower edge). Note that an adhesive is injected into the space V in the vicinity of the groove 32a in FIG.

  With such a configuration, a load applied to the top plate 30 is applied to the reinforcing member 33 via the elastic sheet 37. Since the reinforcing member 33 has a structure in which the bending strength is increased as described above, the top plate 30 is supported with almost no bending, and the reinforcing member 33 is supported by the support portion 32c. Therefore, the top plate 30 is supported from the back surface side by the reinforcing member 33, and the top plate 3 as a whole with respect to a load can secure a necessary strength. In addition, the reinforcing member 33 can be placed along the top plate 30 only in two front and rear partial areas. Therefore, even if the reinforcing member 33 is provided, an increase in weight can be suppressed and the weight can be reduced. . Furthermore, the structure which only constructs the reinforcement member 33 to the outer frame member 32 is simple, and an assembly is easy.

  Moreover, the remaining dimension from the back stove hole 30a of the top plate 30 to the end on the back side (contact surface with the middle plate 31) is short, or the top plate 30 has a load applied to the center in the width direction. The insufficient strength on the back side can be sufficiently compensated by the reinforcing member 33 on the back side. On the other hand, the front side of the top plate 30 tends to warp upward due to thermal strain, but the reinforcing member 33 on the front side does not allow the top plate 30 to warp due to excellent bending strength against a vertical load. Therefore, the warp of the top plate 30 on the near side can be reliably prevented.

As shown in FIG. 4C, a back plate 36 is fitted between the top plate 30 and an elastic sheet 37 between the left and right side surfaces of the top plate 30, and a space near the groove 32a. An adhesive is injected into V. The load applied to the top plate 30 is supported by the support portion 32 c from the elastic sheet 37 through the back plate 36. Thereby, the downward movement of the top plate 30 can be restricted and can be prevented from coming off.
In addition, the other groove | channel 32b and the support part 32d are used similarly in order to support the intermediate | middle board 31 using the back plate 35 shown in FIG. 2 (illustration is abbreviate | omitted).

  Next, a method for assembling the top plate as described above will be described with reference to FIGS. 5 to 7 are rear views of the top plate, and FIG. 8 is a plan view. 5-8, the shape of each part is simplified more than FIGS. 1-4, and the width | variety of the outer frame member 32 is also displayed thickly in order to make it easy to see.

First, in FIG. 5, the plate body 3A (top plate 30, middle plate 31) is placed on the outer frame member 32, and the groove 32a (FIG. 4) is filled with an adhesive. The top plate 30 is provided with holes 30c, 30d (fitted holes) for attaching the rings 38, 39 and the reinforcing member 33 as well as screw holes 30e, 30f dedicated for attaching the rings 38, 39.
Next, as shown in FIG. 6, the reinforcing member 33 is applied along the back surface of the plate body so as to be inclined with respect to the width direction. In this way, the reinforcing member 33 whose longitudinal length L2 is longer than the inner method L1 of the outer frame member 32 can be fitted into the groove 32a (FIG. 4) for the installation. it can.

Next, as shown in FIG. 7A, by changing (rotating) the posture of the reinforcing member 33 so as to be parallel to the width direction from the oblique direction, the both end portions are attached to the outer frame member. It fits in the groove | channel 32a formed inside 33, and it is set as the state constructed by the outer frame member 33. FIG. The reinforcing member 33 on the lower side (front side) in the figure is in a state of being supported not only on both ends in the longitudinal direction but also on the three sides (the left and right sides and the lower side in the figure) of the outer frame member 32. (B), (c) is the BB sectional view taken on the line in (a), and CC sectional drawing, respectively. The semicircular hole 33f of the reinforcing member 33 in (b) is formed in order to provide the screw hole 33d close to the bent portion.
The elastic sheet 37 is bonded to the reinforcing member 33 or the top plate 30 in advance.

Thereafter, as shown in FIG. 8 (a) and (B) which is a cross section taken along the line B-B, the rings 38 and 39 are mounted from above, and the screws 8 are inserted into the holes 38a and 39a of the ring and the top plate. And are screwed into the screw holes 33e and 33d (FIG. 7A) of the reinforcing member 33. Accordingly, the top plate 30 and the reinforcing member 33 can be fixed to each other by fastening the three members 38, 39, the top plate 30, and the reinforcing member 33 together.
As described above, the reinforcing member 33 is placed in a predetermined position while changing its posture from obliquely parallel to the width direction of the top plate 3, and is further installed simply by tightening with screws. Can do. Therefore, the top plate 3 is easy to assemble. The rings 38 and 39 are securely fixed by screwing the other holes (38a and 39a) into the screw holes 30e and 30f (FIG. 7) of the top plate 30 through screws.

  The form of the reinforcing member 33 can be variously modified. For example, instead of an angle shape, the cross section may be a T-shape or a drawn shape by press working. Further, a strip-shaped steel plate or the like without a vertical plate portion may be used, but in that case, it is necessary to secure a sufficient plate thickness and to make the end portion thin so that it can be fitted into the groove 32a of the outer frame member 32. There is. In addition, although a C channel member is also conceivable, in this case, it is difficult to fit in the three sides of the outer frame member. However, when the outer frame member 32 is not used and the top plate 30 is fixed directly by screwing or welding, various types of reinforcing members can be used.

In the above-described embodiment, two reinforcing members 33 are provided at the back from the back stove hole 30a and the front from the front stove hole 30b, but instead of or from the back stove hole 30a. It is also possible to provide the front side from the front stove hole 30b, that is, between both the stove holes 30a and 30b so as to extend in the width direction along the back surface of the plate body 3A. In particular, in the case of a cooker having a wide frontage (for example, 75 cm), etc., when further strength is required, it is preferable to provide reinforcing members at three positions in the front and rear. In short, according to the configuration of the frontage of the cooker and each hole (for example, the presence or absence of the grill exhaust hole and the number of stove holes is 2 or 3), in the place that can be installed in the width direction while avoiding the hole, What is necessary is just to build it as needed. On the other hand, a plurality of reinforcing members are not necessarily required, and a configuration of one reinforcing member is also possible when a predetermined strength is obtained.
Further, the reinforcement member can be installed not only in the width direction but also in the depth direction. Furthermore, it is also possible to construct a reinforcing member approximately in an X shape while avoiding each stove hole.

  Further, the plate main body 3A in the above embodiment is configured by the top plate 30 and the middle plate 31, but the configuration of the plate main body is not limited to this and may be a single plate main body.
