Description

本発明は、台所に設置されるキッチンなど流し台に設けられる水槽の制音,結露防止構造およびこれを有する流し台に関する。   The present invention relates to a water tank sound control and condensation prevention structure provided in a sink such as a kitchen installed in a kitchen, and a sink having the same.

流し台としては、キッチン(たとえば、システムキッチン)や洗面化粧台などが挙げられ、流し台には水槽が設けられている。キッチン,洗面化粧台における各水槽は、通常はそれぞれシンク,洗面ボールと呼ばれている。
近年は、ダイニングやリビングに向けて開放したレイアウトのキッチンが次第に普及している。そのため、キッチンで調理,後片付けなどを行うとき、蛇口から吐出する水がシンクに強く当たったり、熱湯でシンクの底部が急激に熱変形を起こすと、衝撃音や反響音(以下、衝撃音等と記載)を発生していた。前記レイアウトのキッチンでは、この衝撃音等がダイニングやリビングに直接伝わりやすいので、調理や後片づけに要する長い時間、会話やテレビの観賞を妨げる要因となっていた。
Examples of the sink include a kitchen (for example, a system kitchen) and a bathroom vanity, and the sink is provided with a water tank. Each tank in the kitchen and vanity is usually called a sink and a wash bowl, respectively.
In recent years, kitchens with a layout that is open for dining and living are becoming increasingly popular. For this reason, when cooking or cleaning up in the kitchen, if the water discharged from the faucet hits the sink strongly, or if the bottom of the sink suddenly undergoes thermal deformation with hot water, impact sound or reverberation sound (hereinafter referred to as impact sound, etc.) Described). In the kitchen with the layout described above, this impact sound or the like is easily transmitted directly to the dining room or living room, which hinders conversation and television viewing for a long time required for cooking and cleaning up.

そこで、衝撃音等を低減する技術としてたとえば実公平7−28215号公報(特許文献1)には、流し台などの水槽の外面に防振用弾性シートを接着し、この防振用弾性シートの上から水槽の外面に結露防止カバーを取付け、防振用弾性シートの全周を含む全体を結露防止カバーで覆う技術が記載されている。

The anti-condensation covers 21, 21a, 21b are filled with the sound-suppressing sheet 20 in the recesses 24, so that there is no possibility that the thin portions caused by the extension of the anti-condensation cover will be lost and damaged.
Since the planar bottom portion of the recess 24 is integrally formed with the corrugation 29 having a wave shape (or a predetermined shape), the rigidity of the recess 24 is improved.

制音用シート20は、矩形(または、所定形状)に形成されて、シンク本体22の底部26の外面に固着されるようになっている。
シンク本体22に一枚の矩形の制音用シート20を固着する場合を示しているが、矩形または所定形状に形成された複数枚(たとえば、二枚,四枚,六枚)の制音用シートを、シンク本体22の底部26の外面に固着してもよい。この場合には、制音用シートの形状,枚数,配置位置に対応して、結露防止カバー21,21a,21bに、各制音用シートが填まり込むための複数の凹部を形成することになる。
The sound damping sheet 20 is formed in a rectangular shape (or a predetermined shape) and is fixed to the outer surface of the bottom portion 26 of the sink main body 22.
Although the case where one rectangular sound-damping sheet 20 is fixed to the sink main body 22 is shown, a plurality of (for example, two, four, six) sheets for sound-damping formed in a rectangular shape or a predetermined shape are shown. The sheet may be fixed to the outer surface of the bottom portion 26 of the sink body 22. In this case, in accordance with the shape, the number of sheets, and the arrangement position of the sound control sheets, a plurality of recesses for inserting the sound control sheets are formed in the dew condensation prevention covers 21, 21a, 21b. Become.

制音用シート20が余裕をもって填まり込みできるように、結露防止カバー21,21a,21bの凹部24の平面視形状は、制音用シート20の平面視形状より若干大きくなっている。
結露防止カバー21,21a,21bの凹部24と制音用シート20はそれぞれ矩形状に形成されており、凹部24の周壁と制音用シート20の周囲の外周縁部との間には全周にわたり、あるいは周囲の一部分に隙間dがある。これにより、結露防止カバー21,21a,21bに乗り上げることなく、制音用シート20の全体が凹部24に余裕をもって填まり込むことができる。
この隙間dは、制音用シート20の全周囲に渡って10mm程度であるが、実施例において隙間dは、いわゆる遊びなので、凹部24と制音用シート20との位置関係により変化可能である。
The planar view shape of the recess 24 of the dew condensation prevention covers 21, 21 a, 21 b is slightly larger than the planar view shape of the sound damping sheet 20 so that the sound damping sheet 20 can be filled with a margin.
The concave portions 24 of the dew condensation prevention covers 21, 21 a, 21 b and the sound damping sheet 20 are each formed in a rectangular shape, and the entire circumference is between the peripheral wall of the concave portion 24 and the outer peripheral edge around the sound damping sheet 20. There is a gap d over or around a part. As a result, the entire sound damping sheet 20 can be fitted into the recess 24 with a margin without running over the condensation prevention covers 21, 21 a, 21 b.
The gap d is about 10 mm over the entire periphery of the sound damping sheet 20, but in the embodiment, the gap d is so-called play and can be changed depending on the positional relationship between the recess 24 and the sound damping sheet 20. .

シンク2,2a,2bでは、凹部24と制音用シート20との間に隙間dが形成されているので、制音用シート20と結露防止カバー21,21a,21bのサイズのばらつき,これら制音用シートと結露防止カバーの取付け精度,制音用シートと結露防止カバーの伸縮などの影響が、隙間dで吸収される。
したがって、結露防止カバー21,21a,21bを取付けるとき、その凹部24を制音用シート20に容易に且つ良好に係合させることができるので、結露防止カバー21,21a,21bの取付け作業が簡単で安定化する。
In the sinks 2, 2 a, 2 b, a gap d is formed between the recess 24 and the sound damping sheet 20, so that the size variation of the sound damping sheet 20 and the dew condensation prevention covers 21, 21 a, 21 b can be reduced. Effects such as the mounting accuracy of the sound sheet and the condensation prevention cover and the expansion and contraction of the sound control sheet and the condensation prevention cover are absorbed by the gap d.
Therefore, when attaching the dew condensation prevention covers 21, 21a, 21b, the concave portion 24 can be easily and satisfactorily engaged with the sound damping sheet 20, so that the dew condensation prevention covers 21, 21a, 21b can be easily attached. To stabilize.

シンク2c(図15,図16)は、制音用シート20と結露防止カバー21cを備えている。
結露防止カバー21cは、カバー底部40cと、シンク本体22の側部27の外周面に固着するために、カバー底部40cの外周縁全周から立ち上がっている立ち上がり部41とを有して、カバー21c全体が一体成形されている。
The sink 2c (FIGS. 15 and 16) includes a sound suppression sheet 20 and a dew condensation prevention cover 21c.
The condensation prevention cover 21c has a cover bottom portion 40c and a rising portion 41 that rises from the entire outer peripheral edge of the cover bottom portion 40c in order to adhere to the outer peripheral surface of the side portion 27 of the sink body 22. The whole is integrally molded.

シンク2,2cの結露防止カバー21,21cは、結露防止カバー21,21cを取付けるときに立ち上がり部41の開口側43を弾性力に抗して強制的に拡げるために、立ち上がり部41には、上下方向に長いリブ状に折曲された少なくとも一つ(ここでは、四つ)の折曲部42が形成されている。折曲部42は、結露防止カバー21,21cの外周面より外方側に突出し、弧状(たとえば、円弧状),V字状,W字状,矩形状などの断面形状を有している。
折曲部42は、立ち上がり部41の曲率半径の小さい四つの角部にそれぞれ配置されている。したがって、立ち上がり部41の開口側43を外側に引っ張れば、角部の折曲部42に力が集中するのでこの四つの折曲部42が主として弾性変形し、開口側43の各辺をバランスよく容易に拡げることができる。
なお、結露防止カバー21,21cに合計四つの折曲部42が形成された場合を示したが、これに限らず、さらに結露防止カバーの任意の位置に任意の数の折曲部42を形成した場合であってもよい。
たとえば、結露防止カバーの曲率半径の小さな他の角部にもさらに折曲部42を形成して合計6個にした場合、角部と角部の間にもさらに折曲部42を形成して合計7個,9個,10個,14個などであってもよい。
The anti-condensation covers 21 and 21c of the sinks 2 and 2c are provided in the rising portion 41 in order to forcibly expand the opening side 43 of the rising portion 41 against the elastic force when the anti-condensation covers 21 and 21c are attached. At least one (four in this case) bent portion 42 is formed that is bent into a long rib shape in the vertical direction. The bent portion 42 protrudes outward from the outer peripheral surfaces of the dew condensation prevention covers 21 and 21c, and has a cross-sectional shape such as an arc shape (for example, an arc shape), a V shape, a W shape, or a rectangular shape.
The bent portions 42 are respectively disposed at four corner portions of the rising portion 41 having a small curvature radius. Therefore, if the opening side 43 of the rising portion 41 is pulled outward, the force concentrates on the bent portion 42 at the corner portion. Therefore, the four bent portions 42 are mainly elastically deformed, and each side of the opening side 43 is well balanced. Can be easily expanded.
In addition, although the case where the total four bending parts 42 were formed in the dew condensation prevention covers 21 and 21c was shown, not only this but the arbitrary number of bending parts 42 is formed in the arbitrary positions of a dew condensation prevention cover. It may be the case.
For example, when the bent portions 42 are further formed in other corner portions having a small radius of curvature of the dew condensation prevention cover to make a total of six, the bent portions 42 are further formed between the corner portions. There may be a total of 7, 9, 10, 14, etc.

シンク2,2cでは、立上がり部41に折曲部42が形成されているので、シンク本体22,結露防止カバー21,21cのサイズのばらつき,これらシンク本体22と結露防止カバー21,21cとの取付け精度,結露防止カバー21,21cの伸縮などの影響が、折曲部42で吸収される。
したがって、結露防止カバー21,21cを拡げて、シンク本体22に容易且つ良好に係合させることができるので、結露防止カバー21,21cの取付け作業が簡単で安定化する。
結露防止カバー21,21a,21cは、立上がり部41を有しているが、所定の強度を有しその取付け前には自立可能で全体が一体成形されている。したがって、結露防止カバー21,21a,21cは、その搬送,保管など取扱い作業および水槽に填め込む取付け作業が容易である。
In the sinks 2 and 2c, since the bent portion 42 is formed in the rising portion 41, the sizes of the sink main body 22 and the dew condensation prevention covers 21 and 21c are varied, and the sink body 22 and the dew condensation prevention covers 21 and 21c are attached. The bent part 42 absorbs influences such as accuracy and expansion / contraction of the condensation prevention covers 21 and 21c.
Therefore, the dew condensation prevention covers 21 and 21c can be expanded and easily and satisfactorily engaged with the sink body 22, so that the installation work of the dew condensation prevention covers 21 and 21c is simple and stable.
The condensation prevention covers 21, 21 a, and 21 c have a rising portion 41, but have a predetermined strength and can be self-supported before being attached and are integrally formed as a whole. Therefore, the dew condensation prevention covers 21, 21a, 21c are easy to handle, such as transport and storage, and to be installed in the water tank.

制音用シートと結露防止カバーはそれぞれ一層構造であってもよいが、本実施例および各変形例のシンク2,2a〜2cにおける制音用シート20は、シンク本体22の底部26の外面に固着するための弾性層50と、弾性層50の外面側の拘束層51とを貼り合わせた複数層構造(ここでは、二層構造)をなしている(図5〜図7,図14参照)。
弾性層50は、シンク本体22が衝撃などで振動すると、シンク本体22と一緒に変形動作してシンク本体22の振動を低減させる制振機能を発揮する。拘束層51は、弾性層50が振動で変形する動作を、拘束する機能を有している。
Each of the sound damping sheet and the condensation prevention cover may have a single-layer structure, but the sound damping sheet 20 in the sinks 2, 2 a to 2 c of the present embodiment and the modified examples is formed on the outer surface of the bottom portion 26 of the sink body 22. It has a multi-layer structure (here, a two-layer structure) in which an elastic layer 50 for fixing and a constraining layer 51 on the outer surface side of the elastic layer 50 are bonded together (see FIGS. 5 to 7 and FIG. 14). .
When the sink main body 22 vibrates due to an impact or the like, the elastic layer 50 performs a deformation operation together with the sink main body 22 and exhibits a damping function that reduces the vibration of the sink main body 22. The constraining layer 51 has a function of constraining the operation of the elastic layer 50 being deformed by vibration.

弾性層50の下面側の粘着層が拘束層51の上面に固着することにより、弾性層50と拘束層51は一体化している。制音用シート20をシンク本体22に取付ける前までは、弾性層50の上面側の粘着層は全体が保護カバー(図示せず)により覆われている。
制音用シート20をシンク本体22の底部26に取付ける直前に、保護カバーを取り外せば、弾性層50の上面側の粘着層が露出して、これをシンク本体22の底部26の外面に接着させることができ、制音用シート20がシンク本体22の底部外面に固着する。
When the adhesive layer on the lower surface side of the elastic layer 50 is fixed to the upper surface of the constraining layer 51, the elastic layer 50 and the constraining layer 51 are integrated. The adhesive layer on the upper surface side of the elastic layer 50 is entirely covered with a protective cover (not shown) until the sound damping sheet 20 is attached to the sink body 22.
If the protective cover is removed immediately before attaching the sound-damping sheet 20 to the bottom portion 26 of the sink body 22, the adhesive layer on the upper surface side of the elastic layer 50 is exposed, and this is adhered to the outer surface of the bottom portion 26 of the sink body 22. The sound damping sheet 20 is fixed to the bottom outer surface of the sink body 22.

弾性層50自体は、粘着弾性層の上面と下面にそれぞれ粘着層を貼り付けた三層構造で且つ厚みが約6mmの板材であり、その素材は、硬質または軟質のゴム(好ましくは、ブチルゴム),合成樹脂,無機充填材および軟化剤などの混合物からなっている。
拘束層51は、ステンレス(たとえば、SUS304)製で厚みが約0.1mmの金属板である。なお、拘束層51は、他の金属製(たとえば、アルミニウム製)または樹脂製の板材であってもよい。
The elastic layer 50 itself is a plate material having a three-layer structure in which an adhesive layer is bonded to each of the upper and lower surfaces of the adhesive elastic layer and a thickness of about 6 mm. The material is hard or soft rubber (preferably butyl rubber). It consists of a mixture of synthetic resin, inorganic filler and softener.
The constraining layer 51 is a metal plate made of stainless steel (for example, SUS304) and having a thickness of about 0.1 mm. The constraining layer 51 may be another metal (for example, aluminum) or resin plate.

弾性層50を構成するゴムなどの制振材料は、内部ロスが大変大きい材料であり、振動伝達部位に直接貼り付けることにより、振動エネルギーを熱エネルギーに変換し、共振時の振動やこれに伴い発生する固体伝播音を低減することができる。
エネルギーの損失係数に対しては制振材料の厚さ比の影響が大きいが、一定の厚さ比に対して損失係数は飽和する特性を有している。一般的には、制振材料の厚みが基板(ここでは、シンク本体22の底部26)の厚みに対して約1ないし3倍にするのが、効率のよい使い方になる。
単層でシート状の制振材料またはシート状の制振材料同士を重ね合わせた非拘束タイプの制振用シートは、弾性層のみを有し拘束層を有しておらず、弾性層は振動により伸縮変形動作するが制振効果はそれほど上昇しない。そのため、非拘束タイプで制振効果を発揮しようとして制振用シートの厚みを必要以上に厚くすると、制振用シートが重くなってシンク本体との接着部に加わる重量が重くなってしまう。
The damping material such as rubber constituting the elastic layer 50 is a material having a very large internal loss. By directly attaching it to the vibration transmitting portion, the vibration energy is converted into thermal energy, and vibrations at the time of resonance and along with this. The generated solid propagation sound can be reduced.
Although the influence of the thickness ratio of the damping material is large on the energy loss coefficient, the loss coefficient has a characteristic of saturation for a certain thickness ratio. In general, it is efficient to make the thickness of the damping material about 1 to 3 times the thickness of the substrate (here, the bottom portion 26 of the sink body 22).
Single-layer sheet-like damping material or non-restraining type damping sheet with sheet-like damping materials superimposed on each other has only an elastic layer and no constraining layer. However, the vibration control effect does not increase so much. Therefore, if the thickness of the vibration damping sheet is increased more than necessary in order to exhibit the vibration damping effect in the non-constrained type, the vibration damping sheet becomes heavy and the weight applied to the bonding portion with the sink body becomes heavy.

そこで、本発明では、制振材料からなる弾性層50に、この弾性層50の変形動作を拘束するための拘束層51を貼り合わせた複数層構造(ここでは、二層構造)の制音用シート20としている。
この制音用シート20は、拘束層51を設けて弾性層50の変形動作を拘束することにより、「ずり変形」を生ぜしめエネルギー吸収を行うことで、振動さらには固体伝播音の低減を図っており、衝撃音等を効果的に低減している。
また、非拘束タイプと比べて、制音用シート20全体の厚みを薄くして軽量化できるので、接着部の負担が軽減される。
Therefore, in the present invention, for the sound damping of a multi-layer structure (here, a two-layer structure) in which a constraining layer 51 for constraining the deformation operation of the elastic layer 50 is bonded to the elastic layer 50 made of a vibration damping material. The sheet 20 is used.
This sound damping sheet 20 is provided with a constraining layer 51 to constrain the deformation operation of the elastic layer 50, thereby generating “shear deformation” and absorbing energy, thereby reducing vibrations and solid-borne sound. This effectively reduces impact noise.
Moreover, since the thickness of the sound damping sheet 20 as a whole can be reduced and reduced in weight as compared with the unconstrained type, the burden on the bonding portion is reduced.

シンク本体22が金属製の場合、制音用シート20の拘束層51も同種の金属製にするのが好ましい。
シンク本体22がステンレス(たとえば、SUS304)製の場合、拘束層51を同種金属であるステンレス(たとえば、SUS304)製にしている。こうすれば、制音用シート20の貼り付け作業のばらつきなどで、拘束層51がシンク本体22に直接触れている場合でも、異種金属の電食による錆の発生を防止することができる。
When the sink body 22 is made of metal, it is preferable that the constraining layer 51 of the sound damping sheet 20 is also made of the same kind of metal.
When the sink body 22 is made of stainless steel (for example, SUS304), the constraining layer 51 is made of stainless steel (for example, SUS304) that is the same kind of metal. In this way, even when the constraining layer 51 is in direct contact with the sink main body 22 due to variations in the operation of attaching the sound damping sheet 20, it is possible to prevent the occurrence of rust due to electrolytic corrosion of dissimilar metals.

シンク2,2a〜2cにおける結露防止カバー21,21a〜21cは、シンク本体22の外面23(および、制音用シート20)に固着するための樹脂製発泡体層55と、樹脂製発泡体層55の外面側の樹脂製無発泡体層56とを貼り合わせた複数層構造(ここでは、二層構造)をなしている(図11等参照)。
結露防止カバー21,21a〜21cの素材としては、ポリプロピレン(PP),ポリスチレン(PS),ポリエチレン(PE)などの合成樹脂があり、これらの素材は熱伝導率が小さいので十分な結露防止機能を発揮する。
図示する結露防止カバー21,21a〜21cは、たとえば架橋ポリプロピレン系樹脂を素材とした二層構造である。シンク本体22側の樹脂製発泡体層55は、比較的柔らかいポリプロピレン発泡体(厚みt=3mm)からなっている。外側の樹脂製無発泡体層56は、比較的固いポリプロピレン無発泡体(厚みt=0.33mm)からなっており、発泡体層55と無発泡体層56は真空成形品である。
このように、柔らかい樹脂製発泡体層55と固い樹脂製無発泡体層56とを貼り合わせたので、樹脂製無発泡体層56が補強材としての機能を発揮する。したがって、結露防止カバー21,21a〜21cは、破れにくくまた所定の強度を有してその取付け前には自立可能である。樹脂製無発泡体層56が、外側に位置して意匠面となるので、発泡面が露出することがなく外観的に良好である。
制音用シート20と結露防止カバー21,21a〜21cを、それぞれ二層構造(複数層構造)にしたので、シンク2,2a〜2cの内側と外側に温度差があっても制音用シート20と結露防止カバーに反りが生じにくくなって脱落しにくくなる。
The condensation prevention covers 21, 21 a to 21 c in the sinks 2, 2 a to 2 c are a resin foam layer 55 for fixing to the outer surface 23 (and the sound damping sheet 20) of the sink body 22, and a resin foam layer A multi-layer structure (in this case, a two-layer structure) is formed by adhering 55 to the non-foamed resin layer 56 on the outer surface side (see FIG. 11 and the like).
Condensation prevention covers 21, 21 a to 21 c are made of synthetic resin such as polypropylene (PP), polystyrene (PS), polyethylene (PE), etc., and these materials have a low thermal conductivity and thus have sufficient dew condensation prevention functions. Demonstrate.
The dew condensation prevention covers 21, 21 a to 21 c shown in the figure have a two-layer structure made of, for example, a cross-linked polypropylene resin. The resin foam layer 55 on the sink body 22 side is made of a relatively soft polypropylene foam (thickness t = 3 mm). The outer resin non-foamed layer 56 is made of a relatively hard polypropylene non-foamed material (thickness t = 0.33 mm), and the foam layer 55 and the non-foamed layer 56 are vacuum-formed products.
Thus, since the soft resin foam layer 55 and the hard resin non-foam layer 56 are bonded together, the resin non-foam layer 56 functions as a reinforcing material. Therefore, the anti-condensation covers 21, 21a to 21c are not easily torn and have a predetermined strength, and can stand on their own before being attached. Since the non-foamed resin layer 56 is located on the outer side and becomes a design surface, the foamed surface is not exposed and the appearance is good.
Since the sound suppression sheet 20 and the dew condensation prevention covers 21, 21a to 21c have a two-layer structure (multi-layer structure), even if there is a temperature difference between the inside and the outside of the sinks 2, 2a to 2c, the sound suppression sheet 20 and the anti-condensation cover are less likely to warp and fall off.

次に、シンク本体22に、制音用シート20と結露防止カバー21,21a〜21cを取付ける手順について説明する。
シンク2,2a〜2cにおいて、まず最初に、シンク本体22の外面23のうち、制音用シート20と結露防止カバーを固着する部位を脱脂して表面を清浄にする。次いで、シンク本体22に、制音用シート貼り付け用の位置決め治具を填め込む。次に、所定寸法の矩形状にカットして納入された制音用シート20の保護カバーを取り除いて、弾性層50の粘着層を露出させる。
この粘着層には既に接着剤が塗布されているので、制音用シート20をシンク本体22の底部26に貼り付ける。位置決め治具を使用しているので、制音用シート20を所定位置に精度よく位置決めした状態で貼り付けることができる。この貼り付け時には、接着面のエアを抜きながら端から馴染ませるのが好ましい。
Next, a procedure for attaching the sound control sheet 20 and the dew condensation prevention covers 21, 21a to 21c to the sink body 22 will be described.
In the sinks 2, 2 a to 2 c, first, the surface of the outer surface 23 of the sink main body 22 where the sound damping sheet 20 and the dew condensation prevention cover are fixed is degreased to clean the surface. Next, a positioning jig for attaching a sound damping sheet is fitted into the sink body 22. Next, the protective cover of the sound-damping sheet 20 cut into a rectangular shape having a predetermined dimension is removed, and the adhesive layer of the elastic layer 50 is exposed.
Since this adhesive layer has already been coated with an adhesive, the sound damping sheet 20 is attached to the bottom 26 of the sink body 22. Since the positioning jig is used, the sound damping sheet 20 can be attached in a state of being accurately positioned at a predetermined position. At the time of this sticking, it is preferable to let it acclimate from the end while removing air from the bonding surface.

位置決め治具を取り外した後、結露防止カバーを貼り付けるための接着剤を、シンク本体22の底部26の外面,側部27の外周面,制音用シート20の表面(拘束層51の表面)などの固着予定の部位に塗布する。シンク2a,2bの場合も、結露防止カバー21a,21bの形状に応じて、固着予定の部位に接着剤を塗布する。
その後、結露防止カバー20,20a〜20cを、制音用シート20を覆ってシンク本体22の外面23と制音用シート20に固着すれば、シンク2,2a〜2cが完成する。
After removing the positioning jig, an adhesive for attaching the dew condensation prevention cover is applied to the outer surface of the bottom 26 of the sink body 22, the outer peripheral surface of the side 27, and the surface of the sound damping sheet 20 (the surface of the constraining layer 51). Apply to the site to be fixed. Also in the case of the sinks 2a and 2b, an adhesive is applied to a portion to be fixed according to the shape of the dew condensation prevention covers 21a and 21b.
After that, if the condensation prevention covers 20, 20a to 20c cover the sound suppression sheet 20 and are fixed to the outer surface 23 of the sink body 22 and the sound suppression sheet 20, the sinks 2, 2a to 2c are completed.

結露防止カバー21,21cの立ち上がり部41には、折曲部42が一体成形されている。したがって、結露防止カバー21,21cを取付けるのに、開口側43を外方に引っ張ると、立上がり部41が、弾性力に抗して主として折曲部42のところで容易に弾性変形して、開口側43を拡げることができる。
こうして開口部43側を拡げた状態で、結露防止カバー21,21cをシンク本体22に係合させて、結露防止カバー21,21cを破損することなく容易にシンク2,2cに取付けることができる。
A bent portion 42 is formed integrally with the rising portion 41 of the dew condensation prevention covers 21 and 21c. Therefore, when attaching the dew condensation prevention covers 21 and 21c, when the opening side 43 is pulled outward, the rising portion 41 is easily elastically deformed mainly at the bent portion 42 against the elastic force, so that the opening side 43 can be expanded.
In this way, the condensation prevention covers 21 and 21c can be engaged with the sink main body 22 with the opening 43 side expanded, and the condensation prevention covers 21 and 21c can be easily attached to the sinks 2 and 2c without being damaged.

結露防止カバー21,21cを取付けるときは、既にシンク本体22などに接着剤が塗布されているので、結露防止カバー21,21cの入れ込み初期に、シンク本体22の側部外周面の塗布済み接着剤に結露防止カバー21,21cが接触すると、そこでくっついてしまって入れ込み作業が中断してしまう。
そこで、本発明の結露防止カバー21,21cは、折曲部42を設けて立ち上がり部41の開口側43を容易に拡げることができるようにしたので、結露防止カバー21,21cの入れ込み作業が容易になり、接着作業性が良好になる。
折曲部42が形成されているので、結露防止カバー21,21cは、取付け後の状態でしわなどの変形が生じにくい。また、結露防止カバー21,21cの素材として、伸びにくい素材や硬くて変形しにくい素材を使用することができる。
組み込まれた後の結露防止カバー21,21cは、その弾性により元の形状に復元しようとするので、立ち上がり部41が、シンク本体22の外面23に対して隙間を生じることなく密着する。その結果、結露防止機能が有効に発揮されるとともに、外観上も好ましい。
When the condensation prevention covers 21 and 21c are attached, since the adhesive has already been applied to the sink body 22 and the like, the applied adhesive on the outer peripheral surface of the side of the sink body 22 at the initial insertion of the condensation prevention covers 21 and 21c. When the dew condensation prevention covers 21 and 21c come into contact with each other, they stick together and interrupt the insertion work.
Therefore, the dew condensation prevention covers 21 and 21c of the present invention are provided with the bent portion 42 so that the opening side 43 of the rising portion 41 can be easily expanded, so that the dew condensation prevention covers 21 and 21c can be easily inserted. And the adhesion workability is improved.
Since the bent portion 42 is formed, the anti-condensation covers 21 and 21c are unlikely to be deformed such as wrinkles in the state after being attached. In addition, as the material for the condensation prevention covers 21 and 21c, a material that does not easily stretch or a material that is hard and difficult to deform can be used.
Since the dew condensation prevention covers 21 and 21c after being assembled try to be restored to their original shape due to their elasticity, the rising portion 41 is in close contact with the outer surface 23 of the sink body 22 without generating a gap. As a result, the dew condensation prevention function is effectively exhibited and the appearance is also preferable.

結露防止カバー21,21a〜21cは、所定の強度を有して全体的に一体成形されており、これを取付けた状態では部分的に引っ張られて薄くなる部位がないので、必要な板厚が確保されて破損しにくくなる。
結露防止カバー21,21a〜21cの樹脂製発泡体層55は、シンク本体22に固着しているので、結露防止機能に加えて制音機能も発揮する。また、結露防止カバー21,21a〜21cは樹脂製無発泡体層56が設けられて重さが増しているので、シンク2,2a〜2cの振動が低減し、騒音低減効果を発揮する。
The anti-condensation covers 21, 21a to 21c have a predetermined strength and are integrally formed as a whole, and there is no portion that is partially pulled and thinned when the cover is attached. Secured and less likely to break.
Since the resin foam layers 55 of the dew condensation prevention covers 21, 21 a to 21 c are fixed to the sink main body 22, a sound damping function is exhibited in addition to the dew condensation prevention function. Further, since the dew condensation prevention covers 21, 21a to 21c are provided with the resin non-foamed layer 56 and increase in weight, the vibration of the sinks 2, 2a to 2c is reduced, and the noise reduction effect is exhibited.

結露防止カバー21,21a,21bを取付けると、制音用シート20は、結露防止カバー21,21a,21bの凹部24に填まり込むので、シンク本体22の外面23にしっかりと固着される。したがって、結露防止カバー21,21a,21bは、その一部が剥がれて浮きが生じるようなことはない。
なお、制音用シート20を結露防止カバー21,21a,21bの凹部24に予め固着して一体化した後、これらをシンク本体22に取付けるようにしてもよい。この場合には、凹部24の平面視形状を、制音用シート20の平面視形状とほぼ同じかまたは若干大きくして、制音用シート20と凹部24の周壁との間の隙間dの寸法を小さくしてもよい。
When the condensation prevention covers 21, 21 a, 21 b are attached, the sound damping sheet 20 fits into the recess 24 of the condensation prevention covers 21, 21 a, 21 b, and is thus firmly fixed to the outer surface 23 of the sink body 22. Therefore, the dew condensation prevention covers 21, 21a, 21b are not partly peeled off to cause floating.
Alternatively, the sound damping sheet 20 may be attached to the sink body 22 after being fixed and integrated in advance in the concave portions 24 of the dew condensation prevention covers 21, 21 a, 21 b. In this case, the plan view shape of the recess 24 is substantially the same as or slightly larger than the plan view shape of the sound damping sheet 20, and the size of the gap d between the sound control sheet 20 and the peripheral wall of the recess 24. May be reduced.

次に、本発明について行った実験について説明する。図17(A)は衝撃音等に関する実験結果を示す図、図17(B)は測定位置を示す説明図である。
この実験の試験体は「従来A」,「従来B」,「本発明」における各シンクであり、各シンクにおける水はね音,コップを落下させて発生した音,お湯のボコつき音をそれぞれ測定した。各試験体(シンク)をシステムキッチンSに組み込んだ状態で測定した。
図17(A)中の数値は、各試験体につき同じ条件を3回ずつ繰り返し、そのとき測定した値の平均値を示している。実験条件は下記の通りであり、符号tは厚みを示している。
Next, experiments conducted on the present invention will be described. FIG. 17A is a diagram showing experimental results regarding impact sound and the like, and FIG. 17B is an explanatory diagram showing measurement positions.
The specimens of this experiment are the sinks in “Conventional A”, “Conventional B”, and “Invention”, and the water splash sound in each sink, the sound generated by dropping the cup, and the sound of boiling water are shown. It was measured. Each specimen (sink) was measured in a state where it was incorporated in the system kitchen S.
The numerical values in FIG. 17A indicate the average value of the values measured at that time by repeating the same conditions three times for each specimen. The experimental conditions are as follows, and the symbol t indicates the thickness.

・従来A(シンク):薄い結露防止カバー(発泡PE(t=3mm))のみ
・従来B(シンク):制音用シート(ゴム(t=6mm))のみ
・本発明(シンク2):制音用シート(ゴム等の混合物(t=6mm)+SUS304(t=0.1mm))20+結露防止カバー(t=3mm)21
・測定位置:シンク中央の前方側縁部の鉛直上方で且つ床面から155cmの高さ位置に騒音計Gを設置して衝撃音等を測定。
・ Conventional A (sink): only thin anti-condensation cover (foamed PE (t = 3 mm)) ・ Conventional B (sink): only sound control sheet (rubber (t = 6 mm)) ・ Invention (sink 2): control Sound sheet (mixture of rubber and the like (t = 6 mm) + SUS304 (t = 0.1 mm)) 20 + condensation prevention cover (t = 3 mm) 21
・ Measurement position: A sound level meter G is installed vertically above the front edge of the center of the sink and at a height of 155 cm from the floor to measure impact sound and the like.

従来Aのシンクでは、シンク本体に薄い結露防止カバーのみが固着され、従来Bのシンクでは、シンク本体に制音用シートのみが固着されている。本発明のシンクとしては、上述の実施例で示したシンク2を使用した。
水はね音としては、蛇口から一定量の水をシンクに吐出したときの衝撃音等を測定した。コップ落下時の音は、142.7gのコップを2.5cmの高さからシンクに落下させたときの衝撃音等を測定した。お湯のボコつき音は、シンクにいきなり熱湯を流したり、熱湯と冷水とを交互に流したときに、シンクが熱変形して発生する音の有無を測定した。
図17(A)から分かるように、本発明のシンク2では、水はね音とコップ落下時の音は従来A,従来Bと比較して低減されており、また、お湯のボコつき音の発生は一回もなかった。したがって、本発明によれば、シンクで発生する衝撃音等を低減させることができることが分かる。
In the conventional A sink, only the thin dew condensation prevention cover is fixed to the sink main body, and in the conventional B sink, only the sound damping sheet is fixed to the sink main body. As the sink of the present invention, the sink 2 shown in the above embodiment was used.
As a water splash sound, an impact sound when a certain amount of water was discharged from a faucet to a sink was measured. The sound when the cup dropped was measured as the impact sound when a 142.7 g cup was dropped from a height of 2.5 cm onto the sink. As for the sound of hot water, the presence or absence of sound generated by hot deformation of the sink when hot water was suddenly poured into the sink or when hot water and cold water were alternately flowed was measured.
As can be seen from FIG. 17 (A), in the sink 2 of the present invention, the water splash sound and the sound when the cup is dropped are reduced compared to the conventional A and the conventional B, and There was no outbreak. Therefore, according to the present invention, it can be seen that the impact sound and the like generated at the sink can be reduced.
