Description

特許法第30条第2項適用 刊行物の発行日 平成27年2月3日 添付した刊行物を配布した。Article 30, Paragraph 2 of the Patent Act applied Publication date February 3, 2015 The attached publication was distributed.

本発明は、システムキッチンの構成要素となり得るキッチンシンクに関する。 The present invention relates to a kitchen sink that can be a component of a system kitchen.

従来のキッチンシンクには、その内面に段差部が設けられているタイプのものがある。この段差部を利用してプレート状部材を掛け渡し、例えばプレート状部材上の食材を切断する。これにより、キッチンシンクの開口部のスペースを作業場として有効に利用することができる。 Some conventional kitchen sinks have a stepped portion on the inner surface thereof. The stepped portion is used to span the plate-shaped member, and for example, the food material on the plate-shaped member is cut. As a result, the space of the opening of the kitchen sink can be effectively used as a work area.

ところで、単に段差部にプレート状部材を掛け渡すだけの構成では、調理や作業の数が多くなる場合に、スペースが不足する問題が生じる。例えば、食材を切断したり、あるいは水切りプレートとして利用する場合には大きな加重あるいは圧力が発生するものの、単に食材や調理器具等を載置しておくだけの用途として利用する場合には概して大きな加重あるいは圧力は発生しない。 By the way, in a configuration in which the plate-shaped member is simply hung over the stepped portion, there arises a problem of lack of space when the number of cooking and operations increases. For example, when cutting food or using it as a draining plate, a large load or pressure is generated. Or no pressure is generated.

このような状況において、複数の用途に利用する場合の段差部の設計上の工夫がされておらず、また加重あるいは圧力の違いに基づいた段差部の設計上の工夫もされていない。このため、実用性に乏しいキッチンシンクであった。 Under such circumstances, no steps have been devised for use in a plurality of applications, and no steps have been devised based on differences in load or pressure. Therefore, the kitchen sink lacks practicality.

そこで、本発明は、上記課題に鑑み、多用途に対応でき、開口部のスペースを有効に利用可能なキッチンシンクを提供することを目的とする。 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a kitchen sink that can be used for multiple purposes and that can effectively utilize the space of the opening.

発明は、高さ方向の途中に複数の段部が形成された凹部を有するキッチンシンクであって、前記凹部は、底部と第1長辺部と第2長辺部と第1短辺部と第2短辺部とが形成された一体部材を、前記第1長辺部と前記第2長辺部が相対する側部及び前記第1短辺部と前記第2短辺部が相対する側部となるように折り曲げて形成されたものであり、前記段部は、前記第1長辺部及び前記第2長辺部で、かつ前記凹部の内面側の異なる高さの部位に設けられた複数の段差部であり、前記段差部は、第1段差部と、前記第1段差部よりも低い位置の第2段差部と、を有し、前記第1長辺部の第1段差部と前記第2長辺部の第1段差部とが同じ高さに形成されており、前記第1長辺部の第2段差部と前記第2長辺部の第2段差部とが同じ高さに形成されており、前記第2段差部は、前記底部から前記第2段差部に至る側部よりも平面視にて前記凹部の開口面方向の外側に向かって延在した第2平面部を有し、前記第1段差部は、前記第2平面部から前記第1段差部に至る側部よりも平面視にて前記凹部の開口面方向の外側に向かって延在した第1平面部を有し、前記第1平面部と前記第2平面部の延在長さがそれぞれ異なるものであり、前記第1平面部は、その延在方向に直交する前記第1長辺部の長手方向の長さと同じ長さになるように前記第1長辺部の長手方向に沿って連続して形成され、前記第2平面部は、その延在方向に直交する前記第2長辺部の長手方向の長さと同じ長さになるように前記第2長辺部の長手方向に沿って連続して形成され、前記第1長辺部と前記底部との境界部、及び前記第2長辺部と前記底部との境界部にそれぞれ傾斜部が形成され、前記各傾斜部は、前記第1長辺部と前記底部とを接続する平面状の傾斜面、及び前記第2長辺部と前記底部とを接続する平面状の傾斜面をそれぞれ有する、キッチンシンク。 The present invention is a kitchen sink having a recess with a plurality of steps formed in the middle of the height direction , wherein the recess comprises a bottom, a first long side, a second long side and a first short side. and a second short side portion, a side portion where the first long side portion and the second long side portion face each other and a side portion where the first short side portion and the second short side portion face each other The steps are formed by bending to form side portions, and the stepped portions are provided on the first long side portion and the second long side portion and at different heights on the inner surface side of the recess. a plurality of stepped portions , each stepped portion having a first stepped portion and a second stepped portion positioned lower than the first stepped portion; and the first stepped portion of the second long side portion are formed at the same height, and the second stepped portion of the first long side portion and the second stepped portion of the second long side portion are at the same height The second stepped portion extends outward in the direction of the opening surface of the recess in plan view from the side portion extending from the bottom portion to the second stepped portion. and the first stepped portion extends outward in the direction of the opening surface of the recess in plan view from the side portion extending from the second flat portion to the first stepped portion. , wherein the extension lengths of the first plane portion and the second plane portion are different, and the first plane portion is perpendicular to the extension direction of the first long side portion in the longitudinal direction The second plane portion is formed continuously along the longitudinal direction of the first long side portion so as to have the same length as the length of the second long side portion. Continuously formed along the longitudinal direction of the second long side so as to have the same length as the length of the direction, the boundary between the first long side and the bottom, and the second long side and the bottom portion, and each of the inclined portions includes a planar inclined surface connecting the first long side portion and the bottom portion, and a planar inclined surface connecting the second long side portion and the bottom portion. a kitchen sink, each having a planar inclined surface connecting the

複数の段差部のそれぞれは、突出方向に延在する平面部を有し、当該平面部の突出方向に沿った延在長さがそれぞれ異なることにより、用途に最適な平面部が選択可能になる。そして、平面部に例えばプレート状部材を掛け渡すことにより、複数の用途に対応できるキッチンシンクになる。 Each of the plurality of stepped portions has a flat portion extending in the projecting direction, and the extending length of the flat portion along the projecting direction is different, so that the optimum flat portion for the application can be selected. . By laying, for example, a plate-like member over the flat portion, the kitchen sink can be used for a plurality of purposes.

平面部の突出方向に沿った延在長さが長い方の段差部は、平面部の突出方向に沿った延在長さが短い方の段差部よりも高さ方向に沿って高い位置に設けられていることにより、力作業が必要なときには上方の段差部を選択する。例えば、平面部にプレート状部材を掛け渡し、プレート状部材上に作業対象物を載せることにより、作業者の手に近い位置に作業対象物を位置させることができる。この結果、作業効率が向上する。また平面部の突出方向に沿った延在長さが短い方の段差部は下方に位置し、その平面部に例えばプレート状部材を掛け渡し、プレート状部材上に食器類や食材を載せることにより、食器類や食材を載置しておくための用途として利用できる。 The stepped portion with the longer extension length along the projection direction of the flat portion is provided at a higher position along the height direction than the stepped portion with the shorter extension length along the projection direction of the flat portion. Therefore, when force work is required, the upper stepped portion is selected. For example, the work object can be positioned close to the operator's hand by laying the plate-shaped member across the flat portion and placing the work object on the plate-shaped member. As a result, work efficiency is improved. In addition, the stepped portion having the shorter extension length along the projecting direction of the planar portion is positioned downward, and a plate-shaped member, for example, is spanned over the planar portion, and tableware or foodstuffs are placed on the plate-shaped member. , can be used for placing tableware and foodstuffs.

凹部は底部と側部を有し、底部と側部との境界部に傾斜部を有することにより、底部と側部との境界部が直角にならない。傾斜部には傾斜面を有しているため、傾斜面の清掃がし易くなり、キッチンシンクを清潔な状態で維持でき、ひいては製品寿命が向上し得る。 The recess has a bottom and a side, and has an inclined portion at the boundary between the bottom and the side so that the boundary between the bottom and the side is not perpendicular. Since the inclined portion has an inclined surface, the inclined surface can be easily cleaned, the kitchen sink can be kept clean, and the life of the product can be extended.

本発明によれば、多用途に対応でき、開口部のスペースを有効に利用可能なキッチンシンクを提供する。 ADVANTAGE OF THE INVENTION According to this invention, the kitchen sink which can respond to multiple uses and can utilize the space of an opening effectively is provided.

本発明の一実施形態のキッチンシンクの斜視図である。1 is a perspective view of a kitchen sink according to one embodiment of the present invention; FIG. 本発明の一実施形態のキッチンシンクの平面図である。It is a top view of the kitchen sink of one embodiment of the present invention. 図2のA-A間で切断した断面図である。FIG. 3 is a cross-sectional view taken along line AA of FIG. 2;

本発明の一実施形態に係るキッチンシンクについて、図面を参照して説明する。なお、本実施形態で説明した具体的な数値、寸法、材料、加工方法等については、あくまでも例示であり、本発明を限定するものではない。 A kitchen sink according to one embodiment of the present invention will be described with reference to the drawings. It should be noted that the specific numerical values, dimensions, materials, processing methods, etc. described in this embodiment are merely examples and do not limit the present invention.

図1乃至図3に示すように、キッチンシンク10は、底部12と、第1長辺部14Aと、第2長辺部14Bと、第1短辺部14Cと、第2短辺部14Dと、が組み合わされて構成されている。各構成要素は例えば一体部材に形成され、各構成要素を折り曲げて組み合わしたものであるが、各構成要素を別部材にしてそれぞれ組み付けて構成してもよい。 As shown in FIGS. 1 to 3, the kitchen sink 10 includes a bottom portion 12, a first long side portion 14A, a second long side portion 14B, a first short side portion 14C, and a second short side portion 14D. , are combined. Each component is formed as an integral member, for example, and is assembled by bending each component.

なお、第1長辺部14A、第2長辺部14B、第1短辺部14Cおよび第2短辺部14Dは、本発明の側部14として機能する。 The first long side portion 14A, the second long side portion 14B, the first short side portion 14C, and the second short side portion 14D function as the side portion 14 of the present invention.

キッチンシンク10は、第1長辺部14Aと第2長辺部14Bとが相互に対向し、かつ第1短辺部14Cと第2短辺部14Dとが相互に対向しており、全体として凹部16を構成している。 The kitchen sink 10 has a first long side portion 14A and a second long side portion 14B facing each other, and a first short side portion 14C and a second short side portion 14D facing each other. It constitutes the recess 16 .

凹部16の内面には、複数の段差部18が形成されている。複数の段差部18は、凹部16の内面の異なる高さの部位から突出して設けられ、かつ前記突出方向(図1中矢印Y方向)に対して略直交する方向(図1中矢印X方向)に延在している。 A plurality of stepped portions 18 are formed on the inner surface of the recessed portion 16 . A plurality of stepped portions 18 are provided so as to protrude from portions of the inner surface of the recess 16 at different heights, and are provided in a direction (arrow X direction in FIG. 1) that is substantially perpendicular to the projection direction (arrow Y direction in FIG. 1). extends to

各段差部18は、前記突出方向に延在する平面部20を有している。当該平面部20には、例えば、プレート状部材あるいはかご状部材などの何らかの部材が載置され得る。 Each stepped portion 18 has a planar portion 20 extending in the projecting direction. Some member such as a plate-shaped member or a basket-shaped member can be placed on the flat portion 20 .

なお、段差部18は、例えば、第1長辺部14Aと第2長辺部14Bの各内面の相対向する位置に形成されている。しかしながら、この構成に限らず、段差部18は、例えば、第1短辺部14Cと第2短辺部14Dの各内面に相対向する位置に形成されていてもよく、各長辺部14A、14Bと各短辺部14C、14Dの両方に形成されていてもよい。 In addition, the stepped portion 18 is formed, for example, at positions facing each other on the inner surfaces of the first long side portion 14A and the second long side portion 14B. However, the configuration is not limited to this, and the stepped portion 18 may be formed, for example, at a position facing each inner surface of the first short side portion 14C and the second short side portion 14D. It may be formed on both 14B and each of the short sides 14C and 14D.

ここで、段差部18は、例えば、大きさが異なる2種類のものが設けられている。例えば、第1段差部18Aは、第1平面部20Aの突出方向(図1中矢印Y方向)に沿った延在長さが長くなるように構成されている。第2段差部18Bは、第2平面部20Bの突出方向(図1中矢印Y方向)に沿った延在長さが短くなるように設定されている。このため、第1段差部18Aの第1平面部20Aの平面上の面積が、第2段差部18Bの第2平面部20B上の面積よりも大きくなる。 Here, for example, two types of stepped portions 18 having different sizes are provided. For example, the first stepped portion 18A is configured to extend along the projecting direction of the first flat portion 20A (the arrow Y direction in FIG. 1). The second stepped portion 18B is set to have a short extension length along the projecting direction of the second flat portion 20B (the arrow Y direction in FIG. 1). Therefore, the area of the first stepped portion 18A on the plane of the first flat portion 20A is larger than the area of the second stepped portion 18B on the second flat portion 20B.

図3に示すように、第1段差部18Aを構成する第1平面部20Aの突出方向に沿った延在長さをLと、第2段差部18Bを構成する第2平面部20Bの突出方向に沿った延在長さをMとすると、L>Mの関係が成立する。 As shown in FIG. 3, the extension length along the projecting direction of the first plane portion 20A that constitutes the first step portion 18A is L, and the projecting direction of the second plane portion 20B that constitutes the second step portion 18B is Assuming that the extension length along is M, the relationship of L>M is established.

なお、第1長辺部14Aに形成された第1段差部18Aと第2長辺部14Bに形成された第1段差部18Aとは、略同じ高さとなるように形成されている。同様にして、第1長辺部14Aに形成された第2段差部18Bと第2長辺部14Bに形成された第2段差部18Bとは、略同じ高さとなるように形成されている。また、各段差部18A、18Bが第1短辺部14Cと第2短辺部14Dに形成されている構成においても同様である。 The first stepped portion 18A formed on the first long side portion 14A and the first stepped portion 18A formed on the second long side portion 14B are formed to have substantially the same height. Similarly, the second stepped portion 18B formed on the first long side portion 14A and the second stepped portion 18B formed on the second long side portion 14B are formed to have substantially the same height. The same applies to the configuration in which the stepped portions 18A and 18B are formed on the first short side portion 14C and the second short side portion 14D.

第1平面部20Aの突出方向に沿った延在長さが長い第1段差部18Aが、第2平面部20Bの突出方向に沿った延在長さが短い第2段差部18Bよりも凹部16の高さ方向(図3中矢印Z方向)に沿って高い位置に形成されている。 The first stepped portion 18A having a longer extension length along the projecting direction of the first flat portion 20A is more recessed than the second stepped portion 18B having a shorter extension length along the projecting direction of the second planar portion 20B. is formed at a high position along the height direction (direction of arrow Z in FIG. 3).

凹部16を構成する底部12と第1長辺部14Aとの境界部、および凹部16を構成する底部12と第2長辺部14Bとの境界部には、段差部18の延在方向(図1中矢印X方向)に対して略平行に延在する傾斜部22がそれぞれ形成されている。このため、底部12と第1長辺部14Aとの境界部、および底部12と第2長辺部14Bとの境界部は、直角部が形成されていない。 The boundary between the bottom 12 and the first long side 14A forming the recess 16 and the boundary between the bottom 12 and the second long side 14B forming the recess 16 are aligned in the extending direction of the stepped portion 18 (Fig. 1) are formed with inclined portions 22 extending substantially parallel to the direction of arrow X in FIG. Therefore, the boundary between the bottom portion 12 and the first long side portion 14A and the boundary portion between the bottom portion 12 and the second long side portion 14B do not have right-angled portions.

特に、傾斜部22は平面状の傾斜面24を有しているため、傾斜部22の掃除がし易くなる。このため、傾斜部22をいつも清潔な状態に維持しておくことができる。これにより、キッチンシンク10の製品寿命が向上する。 In particular, since the inclined portion 22 has a planar inclined surface 24, cleaning of the inclined portion 22 is facilitated. Therefore, the inclined portion 22 can always be kept clean. This increases the product life of the kitchen sink 10 .

次に、本発明の一実施形態のキッチンシンク10の作用について説明する。 Next, the operation of the kitchen sink 10 of one embodiment of the present invention will be described.

図1乃至図3に示すように、複数の段差部18のそれぞれは、突出方向(図1中矢印Y方向)に延在する平面部20を有し、当該平面部20の突出方向(図1中矢印Y方向)に沿った延在長さが異なることにより、用途に最適な平面部20が選択可能になる。例えば、平面部20にプレート状部材等の何らかの部材を掛け渡すことにより、プレート状部材に食材や食器類を載置でき、複数の用途に対応できるキッチンシンク10になる。 As shown in FIGS. 1 to 3, each of the plurality of stepped portions 18 has a flat portion 20 extending in the projecting direction (arrow Y direction in FIG. 1). By varying the extension length along the Y direction of the middle arrow), it is possible to select the plane portion 20 that is most suitable for the application. For example, by laying some kind of member such as a plate-shaped member across the flat portion 20, foodstuffs and tableware can be placed on the plate-shaped member, and the kitchen sink 10 can be used for a plurality of purposes.

特に、段差部18の平面部20上に載せたプレート状部材を段差部18の延在方向(図1中矢印X方向)に沿ってスライドさせることにより、プレート状部材に載置させた物を移動させることができ、作業効率が向上する。また、複数の段差部18を設けたことにより、それぞれ段差部18に掛け渡される部材を異ならせることにより、複数の作業を同時に行うことができるキッチンシンク10を提供できる。 In particular, by sliding the plate-shaped member placed on the flat portion 20 of the stepped portion 18 along the extending direction of the stepped portion 18 (the direction of the arrow X in FIG. 1), the object placed on the plate-shaped member can be moved. It can be moved to improve work efficiency. In addition, by providing a plurality of stepped portions 18 and different members to be bridged over the stepped portions 18, it is possible to provide the kitchen sink 10 in which a plurality of tasks can be performed at the same time.

複数の段差部18を形成することにより、用途別に段差部18を使い分けることが可能になる。これにより、例えば、洗浄前の食器類と洗浄後の食器類の位置を異ならせることも可能であり、作業効率が向上する。 By forming a plurality of stepped portions 18, it becomes possible to selectively use the stepped portions 18 for different purposes. As a result, for example, the tableware before washing and the tableware after washing can be placed in different positions, improving work efficiency.

第1平面部20Aの突出方向(図3中矢印Y方向)に沿った延在長さが長い方の第1段差部18Aは、第2平面部20Bの突出方向(図3中矢印Y方向)に沿った延在長さが短い方の第2段差部18Bよりも高さ方向(図3中矢印Z方向)に沿って高い位置に設けられていることにより、力作業が必要なときには第1段差部18Aを選択する。これにより、第1段差部18Aの第1平面部20Aに例えばプレート状部材を掛け渡し、プレート状部材上に作業対象物を載せることにより、作業者の手に近い位置に作業対象物を位置させることができる。この結果、作業効率が向上する。 The first stepped portion 18A having a longer extension length along the projecting direction of the first plane portion 20A (the direction of the arrow Y in FIG. 3) extends in the direction of the projection of the second plane portion 20B (the direction of the arrow Y in FIG. 3). By being provided at a position higher in the height direction (the direction of the arrow Z in FIG. 3) than the second stepped portion 18B, which has a shorter extension length along the . Stepped portion 18A is selected. As a result, for example, a plate-shaped member is laid over the first flat portion 20A of the first stepped portion 18A, and the work object is placed on the plate-shaped member, thereby positioning the work object at a position close to the hand of the operator. be able to. As a result, work efficiency is improved.

また、第2平面部20Bの突出方向(図3中矢印Y方向)に沿った延在長さが短い方の第2段差部18Bは下方に位置し、第2平面部20Bに例えばプレート状部材を掛け渡し、プレート状部材上に食器類や食材を載せることにより、食器類や食材を載置しておくための用途として利用できる。 In addition, the second stepped portion 18B having a shorter extension length along the projecting direction of the second flat portion 20B (direction of arrow Y in FIG. 3) is positioned below, and the second flat portion 20B is provided with, for example, a plate-shaped member. It can be used for placing the tableware and foodstuffs on the plate-shaped member.

凹部16を構成する底部12と第1長辺部14Aとの境界部、および底部12と第2長辺部14Bとの境界部には、段差部18の延在方向(図1中矢印X方向)に対して略平行に延在する傾斜部22が形成されているため、底部12と各長辺部14A、14Bとの境界部が直角にならない。傾斜部22の傾斜面24が平面であるため、清掃がし易くなり、キッチンシンク10を清潔な状態で維持でき、ひいては製品寿命が向上し得る。 The boundary between the bottom 12 and the first long side 14A and the boundary between the bottom 12 and the second long side 14B of the recess 16 are aligned in the extending direction of the stepped portion 18 (the direction of the arrow X in FIG. 1). ), the boundaries between the bottom 12 and the long sides 14A and 14B are not perpendicular. Since the inclined surface 24 of the inclined portion 22 is flat, it is easy to clean, the kitchen sink 10 can be maintained in a clean state, and the life of the product can be extended.

なお、凹部16には2種類の段差部18A、18Bを形成した構成を例示したが、2種類に限定されない。例えば、大きさや形状の異なる又は同じである3種類以上の段差部を形成してもよい。 In addition, although the configuration in which two types of stepped portions 18A and 18B are formed in the concave portion 16 is illustrated, the number of types is not limited to two. For example, three or more types of stepped portions having different sizes and shapes or having the same size and shape may be formed.
