Unexamined-Japanese-Patent No. 2004-28405

  In this type of built-in stove, the annular packing intervenes between the peripheral portion of the counter hole and the top plate, thereby preventing the boiling water and the like spilled from the top plate side from entering the counter hole side. However, if the packing only intervenes, a part of the mounting surface in the vicinity of the counter hole in the kitchen counter may be partially warped downward, or if there is another deformation, the flatness of the mounting surface If a deviation occurs, part of the packing is likely to be lifted from the mounting surface in the vicinity of the counter hole. If such packing floats up, the adhesion between the packing and the mounting surface around the counter hole can not be secured, and a gap (a gap between the packing and the mounting surface) generated in the vicinity of the floating portion Boiled water can easily enter the counter hole side.

  The present invention has been made to solve the above-described problems, and a built-in stove installed in a state in which a part is inserted into a counter hole formed in a kitchen counter, such as boiling water from the top plate An object of the present invention is to realize a configuration capable of more reliably preventing liquid from entering the counter hole side.

The built-in stove which is one example of the present invention is

A packing provided along the supported portion of the housing portion;
Have
The peripheral wall portion is accommodated inside the kitchen counter through a counter hole formed in a predetermined mounting surface of the kitchen counter, and the supported portion is installed in a state supported on the mounting surface around the counter hole Built-in stove, and
The packing is
A fixing portion disposed annularly along the supported portion and fixed to the supported portion;
It is arranged in an annular form integrally connected to the fixed part and projecting to the outside of the fixed part, and sandwiched between the mounting surface and the peripheral part of the top plate when the built-in stove is installed. An overhanging portion capable of elastic deformation and bending deformation, which is disposed in a stationary state;
The upper surface of the overhanging portion is formed to project upward and is annularly arranged along the peripheral edge of the top plate, and in contact with the peripheral edge of the top plate when the built-in stove is installed An elastically deformable protrusion that generates an elastic return force that biases the overhanging portion toward the mounting surface;
Equipped with

The built-in stove has a configuration in which a supported portion provided at the upper end of the housing when the built-in stove is installed is supported by a kitchen counter, and an annular packing is attached along the supported portion. . And an overhanging portion is provided in the packing, and the overhanging portion is configured to be capable of elastic deformation and bending deformation, and is sandwiched between the mounting surface of the kitchen counter and the peripheral portion of the top plate when installing the built-in stove Are placed in Since it is such a structure, between the to-be-supported part which protrudes by the upper end part of a housing | casing part, and the mounting surface of a kitchen counter can be sealed by packing. Moreover, on the upper surface of the overhanging portion, an upwardly projecting projecting portion is annularly formed along the peripheral edge of the top plate, and this projecting portion contacts the peripheral edge of the top plate when the built-in stove is installed. An elastic return force is generated so as to bias the overhanging portion toward the mounting surface. With such a configuration, even if a portion of the supported portion or the fixing portion is slightly lifted due to the warpage of the mounting surface or the like, the overhang portion located in the vicinity of the lifted portion is the supported portion or the fixing As in the case of the part, it does not float up, but is displaced so as to bend toward the mounting surface by the elastic return force of the protrusion. Since such displacement occurs partially at the overhanging portion, the overhanging portion is easily maintained in close contact with the mounting surface of the kitchen counter even if the supported portion or a part of the fixing portion is slightly lifted.
Therefore, it can prevent more reliably that liquids, such as a boiled soup which spilled from the top plate, enter into the counter hole side.

Hereinafter, desirable examples of the present invention will be shown. However, the present invention is not limited to the following examples.
The overhanging portion may be configured to overhang the outer side and the lower side of the fixing portion in a non-installation state where the built-in stove is not installed at the kitchen counter.
In this way, even if part of the packing is deformed in the horizontal direction due to some reason (for example, horizontal movement caused by the weight of the built-in stove), the overhang portion and the mounting surface of the kitchen counter Adhesion between the two can be easily secured. Also, even if the protrusion does not come in contact with the peripheral edge of the top plate in the vicinity of the floating portion, the shape when the protruding portion itself is in the non-installed state Since it is easy to approach, the overhang part is easily maintained in close contact with the mounting surface of the kitchen counter.

The projecting portion overhangs at least a part of the projecting portion when viewed in a cross section in a direction orthogonal to the direction in which the projecting portion extends along the projecting portion in the non-installed state where the built-in stove is not installed at the kitchen counter A space may exist between the part. And at the time of installation of a built-in stove, at least one copy of the projection is elastically deformed toward the projection while the projection is sandwiched between the peripheral portion of the top plate and the projection. Good.
In this way, the projection can be deformed to reduce or eliminate the space area when installing the built-in stove. With the configuration in which the height of the protrusion is not easily reduced (a configuration that requires a larger force to reduce the height of the protrusion), the height of the protrusion is too large when the built-in stove is installed, and the top plate is lifted In such a configuration, such a situation is less likely to occur.

(Packing and peripheral configuration)
As shown in FIGS. 4 to 6, the packing 50 is provided along the supported portion 34 of the housing 30 and is annularly attached around the supported portion 34. In this configuration, the peripheral wall portion 32 is configured to include front and rear, left and right wall portions (a front wall portion 32A, a rear wall portion 32B, and a pair of side wall portions (side wall portions 32C and opposite side wall portions)) The support portion 34 is a supported portion on the front side (a supported portion extending along the left-right direction) provided to project forward at the upper end portion of the front wall portion 32A and a rear side at the upper end portion of the rear wall portion 32B. One of the upper end portions of the rear supported portion (the supported portion extending along the left-right direction) provided to project and the side wall portion on one side in the left-right direction (side wall portion on the opposite side to the side wall portion 32C) Provided so as to project to the other side at the upper end portion of the supported portion on one side in the left-right direction (supported portion extending along the front-rear direction) provided to project to the side (the supported portion extending along the longitudinal direction) The other supported part on the other side (in the Includes a supported portion), the extending I. The supported portion 34 is formed in a rectangular frame shape by connecting the front supported portion, the rear supported portion, the supported portion on one lateral side, and the supported portion on the other lateral side. There is. The packing 50 is disposed along the outer edge portion (outer peripheral edge portion) of the supported portion 34 configured as described above. The portion of the packing 50 disposed along the front end side portion (the supported portion on the front side) of the supported portion 34 extends in the left-right direction, and the rear end side portion (the supported side of the supported portion 34) The portion disposed along the section extends in the left-right direction, and the portion disposed along the left-right direction one end side portion of the supported portion 34 (the supported portion on one side in the left-right direction) extends along the front-rear direction A portion extending along the other end side portion in the left-right direction (the supported portion on the other side in the left-right direction) of the supported portion 34 extends in the front-rear direction.

  Each of FIGS. 7 to 10 is a cross-sectional view in the direction orthogonal to the direction in which the protrusion 56 extends along the protrusion 54. 7 shows a part of the cross section C-C in the configuration of FIG. 4 (near the part of the packing 50 disposed along the front end side portion of the supported portion 34 (the supported portion on the front side)) It is shown enlarged. Since the extending direction of the supported portion 34 (specifically, the front end side portion (the supported portion on the front side) of the supported portion 34) is the lateral direction at the position of the cut surface shown in FIG. The direction in which the portion 54 extends along the supported portion 34 is also the lateral direction, and the direction in which the projecting portion 56 extends along the overhanging portion 54 is also the lateral direction. Therefore, the cross section in FIG. 7 is a cross section in a direction orthogonal to the left and right direction (a cross section in a plane direction parallel to the front and rear direction and the vertical direction). 8 is a cross section at the same position as in FIG. 7 when the top plate 2 is assembled, and this cross section is also a cross section in a direction orthogonal to the left and right direction (a plane direction parallel to the front and rear direction and the vertical direction) Cross section). On the other hand, FIG. 9 is disposed along a part of the B-B cross section in the configuration of FIG. 2 (a part of the packing 50 in the left-right direction one end side part of the supported portion 34 (supported portion on one horizontal side) And the vicinity of the portion to be At the position of the cutting plane shown in FIG. 9, the extending direction of the supported portion 34 (specifically, the one lateral end portion of the supported portion 34 (the supported portion on one lateral side)) is the longitudinal direction. Therefore, the direction in which the overhanging portion 54 extends along the supported portion 34 is also the front-rear direction, and the direction in which the projecting portion 56 extends along the overhanging portion 54 is also the front-rear direction. Therefore, the cross section in FIG. 9 is a cross section in a direction orthogonal to the front-rear direction (a cross-section in a plane direction parallel to the left-right direction and the up-down direction).

  When the built-in stove 1 is not installed in the kitchen counter 100, the packing 50 is in a natural state as shown in FIG. On the other hand, when the built-in stove 1 is installed on the kitchen counter 100, the natural state is deformed as shown in FIG. 8 and FIG. The packing 50 is cut in a plane direction orthogonal to the extending direction of the packing 50 at each position, as shown in FIGS. The shape of the cut surface of has the same cross-sectional shape.

The packing 50 includes a fixing portion 52, an overhanging portion 54, and a projecting portion 56.
The fixing portion 52 is annularly disposed along the supported portion 34 formed in a flange shape at the upper end portion 30A of the housing portion 30, and is fixed to the periphery of the supported portion 34. Specifically, as shown in FIG. 9, the shape of the cut surface of the supported portion 34 when cut in the plane direction orthogonal to the extending direction of the packing 50 at the position of most of the circumferential direction of the packing 50 is It has a shape that sandwiches the vicinity of the outer edge up and down, and a rib-like convex part 52A is formed at the lower end of the part that sandwiches up and down. In the example of FIG. 9, the outer edge portion of the supported portion 34 is vertically sandwiched by the upper covering portion 53A and the lower covering portion 53B forming a part of the fixing portion 52, and the upper covering portion 53A and the lower covering portion The part 53B is integrally connected via the connecting part 53C. The convex portion 52A is formed to be convex downward in the lower covering portion 53B, and extends along the direction in which the supported portion 34 extends. For example, at the position of the cutting plane shown in FIG. 9, the extending direction of the supported portion 34 is the front-rear direction, so the direction in which the convex portion 52A extends along the supported portion 34 is also the front-rear direction.

  The overhanging portion 54 is configured so as to be capable of elastic deformation and bending deformation, and is integrally connected to the fixing portion 52 as shown in FIGS. 8 and 9, and is disposed in an annular form projecting to the outside of the fixing portion 52. . Specifically, as shown in FIGS. 8 and 9, a cross section in a direction orthogonal to the direction in which the projecting portion 56 extends along the overhanging portion 54 (specifically, orthogonal to the extending direction of the packing 50 at the cutting position) When the cut surface when cut in the planar direction is viewed, the overhanging portion 54 extends to the side (outside) away from the connecting portion 53C starting from the position of the connecting portion 53C described above. Specifically, the shape of the overhanging portion 54 in the cutting plane as shown in FIG. 8 and FIG. 9 extends obliquely downward so as to be at a lower position as it goes away from the fixing portion 52. As described above, at any position in the circumferential direction of the packing 50, the shape of the overhanging portion 54 in the plane in the plane direction orthogonal to the extending direction of the packing 50 is lower as it goes away from the connecting portion 53C. Such an overhang portion 54 is formed over the entire circumference.

  The projecting portion 56 is configured to be capable of elastic deformation and bending deformation, is formed to project upward on the upper surface of the overhanging portion 54, and is annularly disposed along the peripheral edge portion 2B of the top plate 2. Specifically, as shown in FIGS. 8 and 9, a cross section in a direction orthogonal to the direction in which the projecting portion 56 extends along the overhanging portion 54 (specifically, orthogonal to the extending direction of the packing 50 at the cutting position) (See the cut surface when cut in the planar direction), the protrusion 56 is in the form of a claw projecting upward on the upper surface of the protrusion 54, and It is in the form of a circular arc curved to be convex on the opposite side. When the top plate 2 is not attached to the case 30 as shown in FIG. 7, the protrusion 56 has a relatively large amount of protrusion from the overhanging portion 54, and as shown in FIGS. 8 and 9, the case In the state where the top plate 2 is attached to the portion 30, the tip end side approaches the overhanging portion 54 by being pressed by the vicinity of the peripheral portion 2B of the top plate 2, and the projecting amount is larger than that in FIG. It becomes relatively small. In the state of FIG. 8, FIG. 9, the force (elastic return force) which is going to return to a shape like FIG. 7 has arisen to the protrusion part 56. As shown in FIG. As described above, the force that the projection 56 tries to elastically return is similarly generated at most positions in the circumferential direction of the packing 50 or at all positions in the circumferential direction.

  As shown in FIG. 9, in the non-installed state where the built-in stove 1 is not installed on the kitchen counter 100, when the cross section in the direction orthogonal to the direction in which the projecting portion 56 extends along the overhanging portion 54, the overhanging portion 54 The configuration is such that the fixing portion 52 projects outward and downward. Then, a space 90 is present between at least a part of the projection 56 and the overhang 54. Specifically, when the cross section is viewed in the non-installed state described above, the projecting portion 56 is curved and extended so as to approach the fixed portion 52 as it becomes the upper side, and the projecting portion 54 The space 90 is formed between the inner portion and the inner side of the projection 56, which is located inside the projection 56.

  On the other hand, as shown in FIG. 10, when the mounting surface 102A of the portion covered by the packing 50 is flat all around the periphery of the counter hole 104, the fixing portion is installed when the built-in stove 1 is installed on the kitchen counter 100. The projection 52A provided at the lower end of the contact 52 is in contact with the mounting surface 102A, and the overhanging portion 54 is disposed in a state of being sandwiched between the mounting surface 102A and the peripheral portion 2B of the top plate 2 Be done. Then, at the time of this installation, the protrusion 56 is elastically deformed toward the protrusion 54 so that at least a part thereof approaches the protrusion 54 while being sandwiched by the peripheral portion 2B of the top plate 2 and the protrusion 54. More specifically, the elastic deformation is performed so that the area of the space 90 is reduced or no space 90 is generated as compared with the non-installed state. As described above, at the time of installation, the projecting portion 56 is maintained in a state of generating an elastic return force that biases the projecting portion 54 toward the mounting surface 102A while being in contact with the peripheral portion 2b of the top plate 2. Since such an elastic return force is generated, the mounting surface 102A is temporarily warped in the vicinity of the counter hole 104, and the supported portion 34 and the convex portion 52A are caused due to the warping as shown in FIG. Even if the vicinity floats away from the mounting surface 102A, the overhanging portion 54 is pushed downward by the force of the projecting portion 56 to return to the natural state, and as shown in FIG. The state of contact with the mounting surface 102A is maintained. For example, the mounting surface 102A in the vicinity of the front end portion and the rear end portion of the supported portion 34 configured in a flange shape as shown in FIGS. 4 and 6 is slightly high, and mounting in the vicinity of the longitudinal center position of the supported portion 34 In the case where a warp such that the surface 102A is lowered (a warp in which the center side is slightly recessed downward) is generated, the packing 50 in the vicinity of the center in the front-rear direction is deformed as shown in FIG. The adhesion is maintained even if the lower warp occurs.

Next, the main effects of this configuration are illustrated.
The built-in stove 1 has a configuration in which the supported portion 34 provided on the upper end portion 30A of the housing unit 30 is supported by the kitchen counter 100 at the time of installation installed on the kitchen counter 100. An annular packing 50 is attached to the. And the overhanging part 54 is provided in the packing 50, and this overhanging part 54 is comprised so that elastic deformation and bending deformation are possible, and the installation of the kitchen counter 100 is carried out at the time of installation of the built-in stove 1 like FIG. It is arrange | positioned in the state pinched | interposed between the surface 102A and the peripheral part 2B of the top plate 2. As shown in FIG. With such a configuration, the space between the supported portion 34 protruding at the upper end portion 30A of the housing 30 and the mounting surface 102A of the kitchen counter 100 can be sealed by the packing 50. Moreover, on the upper surface of the overhanging portion 54, an upwardly projecting projecting portion 56 is annularly formed along the peripheral edge portion 2B of the top plate 2, and this projecting portion 56 is used when the built-in stove is installed. The elastic return force is generated so as to bias the overhanging portion 54 toward the mounting surface 102A while being in contact with the peripheral edge portion 2B. With such a configuration, even if a portion of the supported portion 34 or the fixing portion 52 slightly floats up as shown in FIG. 11 due to the warpage of the mounting surface 102A or the like, the tension located in the vicinity of the floating portion The projecting portion 54 is not lifted up like the supported portion 34 and the fixing portion 52, but is displaced so as to bend toward the mounting surface 102 by the elastic return force of the projecting portion 56. Since such displacement occurs partially in the overhanging portion 54, the overhanging portion 54 is in close contact with the mounting surface 102A of the kitchen counter 100 even if the supported portion 34 or the fixing portion 52 is slightly lifted. It becomes easy to be maintained.
Therefore, it can prevent more reliably that liquids, such as a boiled soup which spilled from the top plate 2, enter into the counter hole 104 side.

  As shown in FIG. 9, the overhanging portion 54 projects outward and downward of the fixing portion 52 when the built-in stove 1 is not installed in the kitchen counter 100. In this way, even if part of the packing 50 is deformed in the horizontal direction due to any reason (for example, horizontal movement caused by the weight of the built-in stove 1), the overhang portion 54 and the kitchen counter 100 are placed Adhesion with the mounting surface 102A is easily secured. Further, even if the protrusion 56 does not come into contact with the peripheral portion 2B of the top plate 2 in the vicinity of the floating portion, the shape when the protrusion 54 itself is not installed (outside and below the fixing portion 52) The overhanging portion 54 is easily maintained in a state of being in close contact with the mounting surface 102A of the kitchen counter 100, since the overhanging portion 54 is easily approached.

  The protrusion 56 has a cross section in a direction orthogonal to the direction in which the protrusion 56 extends along the overhang 54 in a non-installed state where the built-in stove 1 is not installed on the kitchen counter 100 (that is, a cross section as shown in FIG. ), There is a space between at least a part of the projecting portion 56 and the overhanging portion 54. And at the time of installation of built-in stove 1 like FIG. 10, at least one part of the said protrusion part 56 is the protrusion part 54, being pinched | interposed into the peripheral part 2B of the top plate 2, and the overhang part 54. It is elastically deformed towards the In this way, the projection 56 can be deformed so as to reduce or eliminate the space area when the built-in stove 1 is installed. If the height of the protrusion is not easily reduced (a configuration that requires a larger force to reduce the height of the protrusion), the height of the protrusion is too large when the built-in stove is installed, and the top plate is too large. However, according to the above configuration, such a situation is less likely to occur.

  Further, as shown in FIGS. 3 and 8, a claw portion 38 for fixing the housing portion 30 to the top plate 2 is provided at the upper end portion of the housing portion 30, and the top plate is formed on the housing portion 30. When mounting 2, the claw 38 is configured to be engaged so as to hook a part of the top plate 2. In such a configuration, if the protrusion 56 is configured to create the space 90 as described above, in the step of hooking the top plate 2 to the claw portion 38, a portion of the top plate 2 is the protrusion 56. Also in the case of contact, the protrusion 56 is easily deformed, and the step of hooking a part of the top plate 2 on the claw 38 is facilitated.
