Description

本発明は冷蔵庫に関する。   The present invention relates to a refrigerator.

冷蔵庫の収納室は、冷蔵室と冷凍室といった具合に複数の収納室に仕切られ、それぞれの収納室に扉が設けられているのが通常の構成である。収納室を仕切る仕切部は庫内の冷気で冷却される。冷却された仕切部の前面部分は、部分的には扉で覆われるものの、庫外に露出する箇所が生じることは避けがたい。仕切部の庫外露出箇所に庫外の空気が接触すると、空気中の水分がそこに結露し、結露水が生じる。結露水が下に垂れるのは好ましくないので、仕切部には庫外露出箇所が冷えすぎないようにする防露装置が設けられる。そのような防露装置のいくつかを紹介する。   The storage compartment of the refrigerator is usually divided into a plurality of storage compartments such as a refrigerator compartment and a freezer compartment, and a door is provided in each compartment. The partition part which partitions a storage chamber is cooled with the cool air in a store | warehouse | chamber. Although the front part of the cooled partition part is partially covered with a door, it is unavoidable that a portion exposed to the outside of the warehouse is generated. When the outside air contacts the outside exposed portion of the partition, moisture in the air condenses there, and condensed water is generated. Since it is not preferable for the dew condensation water to hang down, a dew proofing device is provided in the partition to prevent the exposed portion outside the refrigerator from being too cold. Some of such dew protection devices are introduced.

特許文献１に記載された冷蔵庫では、仕切部の前部に意匠板が配設される。意匠板の背後には冷凍サイクルの放熱側冷媒管が配設される。冷媒管は断熱材に埋め込まれた形になっている。意匠板の上下縁には裏面に向かって折れ曲がった折曲部が形成され、この折曲部の奥行きは折曲部から冷媒管の熱が流出しない程度に設定される。   In the refrigerator described in Patent Document 1, a design plate is disposed in the front part of the partition part. Behind the design plate, a heat radiation side refrigerant pipe of the refrigeration cycle is disposed. The refrigerant pipe is embedded in the heat insulating material. A bent portion that is bent toward the back surface is formed on the upper and lower edges of the design plate, and the depth of the bent portion is set such that heat of the refrigerant pipe does not flow out of the bent portion.

特許文献２に記載された冷蔵庫では、一方の室側の仕切りと他方の室側の仕切りを合わせて１個の仕切部を構成する。仕切りと仕切りの間に仕切板を配置し、この仕切板の背面に放熱パイプを取り付けて、仕切板での結露を防止するようにしている。   In the refrigerator described in Patent Document 2, one partition is configured by combining a partition on one side and a partition on the other side. A partition plate is disposed between the partitions, and a heat radiating pipe is attached to the rear surface of the partition plate to prevent condensation on the partition plate.

特許文献３に記載された冷蔵庫では、仕切部の内部に断面コの字状の補強用空間部を設け、この内部に断熱材を配し、その前面に防露パイプを配し、さらに鉄製の前板を配している。   In the refrigerator described in Patent Document 3, a U-shaped reinforcing space portion is provided inside the partition portion, a heat insulating material is disposed inside the partition portion, a dew-proof pipe is disposed on the front surface thereof, and an iron-made portion is further provided. A front board is arranged.

図６に示すのは従来の仕切部の構造例である。樹脂成型品１００により仕切部の前面部分が構成されるものであり、樹脂成型品１００の前面に放熱パイプ１０１が配管される。放熱パイプ１０１は金属板のプレス成型品からなるパイプホルダ１０２により樹脂成型品１００に固定される。その後、金属板のプレス成型品からなる化粧板１０３が、放熱パイプ１０１を隠すように樹脂成型品１００の前面に取り付けられる。   FIG. 6 shows a structural example of a conventional partition portion. The resin molded product 100 constitutes the front portion of the partition, and a heat radiating pipe 101 is provided on the front surface of the resin molded product 100. The heat radiating pipe 101 is fixed to the resin molded product 100 by a pipe holder 102 made of a metal plate press-molded product. Thereafter, a decorative plate 103 made of a metal plate press-molded product is attached to the front surface of the resin molded product 100 so as to hide the heat radiating pipe 101.

放熱パイプ１０１には高温の冷媒が流れるものであり、この冷媒の熱が化粧板１０３に伝わることにより、化粧板１０３の防露がなされる。化粧板１０３の裏面には、放熱パイプ１０１ががたつかないように押さえ込み、また放熱パイプ１０１からの熱を伝達する目的で、弾性材料からなるクッション１０４が取り付けられている。クッション１０４は、パイプホルダ１０２が存在する箇所と存在しない箇所の間のパイプホルダ１０２の板厚分の段差を吸収する役割も果たす。クッション１０４を構成する弾性材料としては一般的にブチルゴムが用いられる。   A high-temperature refrigerant flows through the heat radiating pipe 101, and the heat of the refrigerant is transmitted to the decorative plate 103, so that the decorative plate 103 is prevented from dew condensation. A cushion 104 made of an elastic material is attached to the back surface of the decorative plate 103 in order to hold the heat radiating pipe 101 so that it does not rattle and to transmit heat from the heat radiating pipe 101. The cushion 104 also serves to absorb a level difference corresponding to the plate thickness of the pipe holder 102 between the place where the pipe holder 102 exists and the place where the pipe holder 102 does not exist. Generally, butyl rubber is used as an elastic material constituting the cushion 104.

本発明は、冷蔵庫の仕切部前面の化粧板の防露を、従来用いられていた部材なしでも確実に行えるようにすることを目的とする。   An object of this invention is to make it possible to reliably perform dew-proofing of the decorative plate on the front surface of the partition portion of the refrigerator without using a conventionally used member.

上記目的を達成するために本発明は、庫内の収納室同士の間を仕切る仕切部の前面に防露用の放熱パイプが配管され、前記放熱パイプは金属製の化粧板で隠される冷蔵庫において、前記放熱パイプは前記仕切部の前面部分を構成する樹脂成型品と前記化粧板の間に挟み付けられて保持されるものであり、前記化粧板は当該化粧板自身に形成された係合部を前記樹脂成型品に形成された係合部に係合させて前記樹脂成型品に取り付けられるものであり、その際前記放熱パイプが偏平化する程度の圧力を前記放熱パイプに対して及ぼすことを特徴としている。   In order to achieve the above object, the present invention provides a refrigerator in which a heat-dissipating pipe for dew prevention is provided on the front surface of a partition that partitions the storage chambers in the cabinet, and the heat-dissipating pipe is hidden by a metal decorative plate. The heat radiating pipe is sandwiched and held between a resin molded product constituting the front portion of the partition and the decorative plate, and the decorative plate has an engaging portion formed on the decorative plate itself. It is engaged with an engaging portion formed on a resin molded product and is attached to the resin molded product, and at that time, a pressure is applied to the heat radiating pipe so that the heat radiating pipe is flattened. Yes.

上記構成の冷蔵庫において、前記化粧板側の係合部とそれに対応する前記樹脂成型品側の係合部は前記化粧板の長さ方向に沿って複数箇所に配置され、全ての係合部が係合したとき、前記化粧板はその長さ方向を含む平面内で、前記収納室の扉に向かって凸となるように湾曲せしめられることが好ましい。   In the refrigerator configured as described above, the engaging portion on the decorative plate side and the corresponding engaging portion on the resin molded product side are arranged at a plurality of locations along the length direction of the decorative plate, and all the engaging portions are arranged. When engaged, the decorative plate is preferably curved so as to be convex toward the door of the storage chamber within a plane including its length direction.

本発明によると、仕切部の前面部分を構成する樹脂成型品とこれに取り付けられる金属製の化粧板の間に放熱パイプを挟み付けるに際し、化粧板は放熱パイプが偏平化する程度の圧力を放熱パイプに対して及ぼすから、化粧板と放熱パイプの密着度が上がり、放熱パイプの熱が効率良く化粧板に伝えられる。これにより化粧板の結露を効果的に防ぐことができる。   According to the present invention, when the heat radiating pipe is sandwiched between the resin molded product constituting the front portion of the partition portion and the metal decorative plate attached thereto, the decorative plate applies pressure to the heat radiating pipe so that the heat radiating pipe is flattened. On the other hand, the degree of adhesion between the decorative plate and the heat radiating pipe is increased, and the heat of the heat radiating pipe is efficiently transmitted to the decorative plate. Thereby, the dew condensation of a decorative board can be prevented effectively.

＜第１実施形態＞
冷蔵庫の筐体構造を図１、２に基づき説明する。冷蔵庫１の筐体２は、庫内の空間が仕切部３によって上下の収納室に仕切られ、上部の収納室が冷凍室４、下部の収納室が冷蔵室５となっている。冷凍室４は扉６で閉ざされ、冷蔵室５は扉７で閉ざされる。仕切部３の前面部の内側にはヘアピン形状を描くように放熱パイプ８が引き回される。放熱パイプ８は銅製である。 <First Embodiment>
The housing structure of the refrigerator will be described with reference to FIGS. As for the housing | casing 2 of the refrigerator 1, the space in a store | warehouse | chamber is divided into an upper and lower storage chamber by the partition part 3, the upper storage chamber becomes the freezer compartment 4, and the lower storage chamber becomes the refrigerator compartment 5. The freezer compartment 4 is closed with a door 6, and the refrigerator compartment 5 is closed with a door 7. A heat radiating pipe 8 is routed inside the front portion of the partition 3 so as to draw a hairpin shape. The heat radiating pipe 8 is made of copper.

図３には扉６及び扉７の詳細構造が示されている。扉６の主な構成要素は、前面の化粧パネル６ａ、冷凍室４側の内板６ｂ、扉６の周囲を囲み且つ化粧パネル６ａと内板６ｂを連結するドアキャップ６ｃ、及びこれら３部材で囲まれる空間に形成される発泡樹脂よりなる断熱層である。扉７の主な構成要素は、前面の化粧パネル７ａ、冷蔵室５側の内板７ｂ、扉７の周囲を囲み且つ化粧パネル７ａと内板７ｂを連結するドアキャップ７ｃ、及びこれら３部材で囲まれる空間に形成される発泡樹脂よりなる断熱層である。内板６ｂ、７ｂは合成樹脂シートをブロー成型したものであり、ドア棚を形成するための凹凸形状を有している。ドアキャップ６ｃ、７ｃは合成樹脂の射出成型品である。   FIG. 3 shows the detailed structure of the door 6 and the door 7. The main components of the door 6 are a front decorative panel 6a, an inner plate 6b on the freezer compartment 4 side, a door cap 6c that surrounds the door 6 and connects the decorative panel 6a and the inner plate 6b, and these three members. It is a heat insulating layer made of a foamed resin formed in the enclosed space. The main components of the door 7 include a front decorative panel 7a, an inner plate 7b on the refrigerator compartment 5 side, a door cap 7c that surrounds the door 7 and connects the decorative panel 7a and the inner plate 7b, and these three members. It is a heat insulating layer made of a foamed resin formed in the enclosed space. The inner plates 6b and 7b are formed by blow molding a synthetic resin sheet and have an uneven shape for forming a door shelf. The door caps 6c and 7c are injection molded products of synthetic resin.

仕切部３は、水平な棚形状の本体部３ａと、本体部３ａに固定されて仕切部３の前面部分を構成する樹脂成型品３ｂを備える。本体部３ａの内部空間には発泡樹脂よりなる断熱層が形成される。樹脂成型品３ｂの前面に放熱パイプ８が配置され、放熱パイプ８は金属板のプレス成型品からなるパイプホルダ９で樹脂成型品３ｂに取り付けられる。   The partition part 3 includes a horizontal shelf-shaped main body part 3 a and a resin molded product 3 b that is fixed to the main body part 3 a and constitutes the front part of the partition part 3. A heat insulating layer made of foamed resin is formed in the internal space of the main body 3a. A heat radiating pipe 8 is disposed on the front surface of the resin molded product 3b, and the heat radiating pipe 8 is attached to the resin molded product 3b by a pipe holder 9 made of a metal plate press-molded product.

樹脂成型品３ｂの前面には金属板のプレス成型品からなる化粧板１０が取り付けられ、放熱パイプ８は化粧板１０で隠される。なお、放熱パイプ８を樹脂成型品３ｂと化粧板１０で挟み付けて保持し、パイプホルダ９を廃止する構成としてもよい。   A decorative plate 10 made of a metal plate press-molded product is attached to the front surface of the resin molded product 3 b, and the heat radiating pipe 8 is hidden by the decorative plate 10. In addition, it is good also as a structure which sandwiches and hold | maintains the thermal radiation pipe 8 with the resin molded product 3b and the decorative board 10, and abolishes the pipe holder 9. FIG.

図３、４に示す通り、化粧板１０は断面コ字形にプレス成型されている。化粧板１０は防錆処理がなされた鋼板を素材とし、それに化粧用の塗装を施したものである。扉６のドアパッキン６ｄに内蔵された磁石６ｅと、扉７のドアパッキン７ｄに内蔵された磁石７ｅは、筐体２を構成する鋼板に吸着すると同時に化粧板１０にも吸着し、これによりドアパッキン６ｄ、７ｄの箇所の気密が保たれる。   As shown in FIGS. 3 and 4, the decorative board 10 is press-molded in a U-shaped cross section. The decorative board 10 is made of a steel plate that has been subjected to a rust-proofing treatment, and a decorative coating is applied thereto. The magnet 6e built in the door packing 6d of the door 6 and the magnet 7e built in the door packing 7d of the door 7 are adsorbed to the steel plate constituting the housing 2 and at the same time adsorbed to the decorative plate 10, whereby the door The airtightness of the portions of the packings 6d and 7d is maintained.

化粧板１０は、それ自身に形成された係合部を樹脂成型品３ｂに形成された係合部に係合させて樹脂成型品３ｂに取り付けられ、同時に樹脂成型品３ｂとの間に放熱パイプ８を挟み付ける。放熱パイプ８は樹脂成型品３ｂの前面に形成されたリブ１１に押し当てられる。   The decorative plate 10 is attached to the resin molded product 3b by engaging the engaging portion formed on the decorative plate 10 with the engaging portion formed on the resin molded product 3b, and at the same time, the heat radiating pipe between the decorative plate 10 and the resin molded product 3b. 8 is sandwiched. The heat radiating pipe 8 is pressed against the rib 11 formed on the front surface of the resin molded product 3b.

化粧板１０側の係合部は上部の縁と下部の縁にそれぞれ上方及び下方に向けて切り起こした爪片１２である。爪片１２は先端を扉６あるいは扉７の側に向けている。樹脂成型品３ｂ側の係合部は爪片１２を受け入れる凹陥孔１３である。なお、樹脂成型品３ｂ側の係合部を爪片とし、化粧板１０側の係合部を凹陥孔または貫通孔としてもよい。   The engaging portion on the decorative board 10 side is a claw piece 12 cut and raised upward and downward at the upper edge and the lower edge, respectively. The tip of the claw piece 12 faces the door 6 or the door 7 side. The engaging portion on the resin molded product 3 b side is a recessed hole 13 that receives the claw piece 12. The engaging portion on the resin molded product 3b side may be a claw piece, and the engaging portion on the decorative board 10 side may be a recessed hole or a through hole.

化粧板１０を樹脂成型品３ｂに嵌め込み、強い力で押し込むと、図４に示す通り爪片１２の先端が凹陥孔１３の内面に係合し、化粧板１０は樹脂成型品３ｂに対し取り付け状態となる。この時化粧板１０は、リブ１１との間で放熱パイプ８が偏平化する程度の圧力を放熱パイプ８に対して及ぼす。放熱パイプ８は、奥行き方向の寸法が圧縮され、上下方向の寸法が延びて、断面が縦長の偏平形状となる。放熱パイプ８は銅製であることから、作業者が化粧板１０を押し込む力で偏平化が可能である。   When the decorative board 10 is fitted into the resin molded product 3b and pushed with a strong force, the tip of the claw piece 12 is engaged with the inner surface of the recessed hole 13 as shown in FIG. 4, and the decorative board 10 is attached to the resin molded product 3b. It becomes. At this time, the decorative plate 10 exerts a pressure on the heat radiating pipe 8 so that the heat radiating pipe 8 becomes flat between the rib 11. The heat radiating pipe 8 is compressed in the depth direction, extends in the vertical direction, and becomes a flat shape with a vertically long cross section. Since the heat radiating pipe 8 is made of copper, it can be flattened by the force with which the operator pushes the decorative plate 10.

偏平化した放熱パイプ８は自身の弾性で化粧板１０に密着する。これにより放熱パイプ８と化粧板１０の密着度が上がるから、放熱パイプ８の熱が効率良く化粧板１０に伝えられる。化粧板１０に接していない部分を含めた、放熱パイプ８の化粧板１０に対する投影面積も、放熱パイプ８の偏平化により増大するから、輻射熱として化粧板１０に伝達される熱量も増大する。これらが相まって、放熱パイプ８が持つ熱を効率的に利用し、化粧板１０の結露を効果的に防ぐことができる。   The flattened heat radiating pipe 8 is in close contact with the decorative plate 10 by its own elasticity. As a result, the degree of adhesion between the heat radiating pipe 8 and the decorative plate 10 increases, so that the heat of the heat radiating pipe 8 is efficiently transmitted to the decorative plate 10. Since the projected area of the heat radiating pipe 8 on the decorative plate 10 including the portion not in contact with the decorative plate 10 also increases due to the flattening of the heat radiating pipe 8, the amount of heat transmitted to the decorative plate 10 as radiant heat also increases. Together, the heat of the heat radiating pipe 8 can be efficiently used, and condensation on the decorative board 10 can be effectively prevented.

化粧板１０を樹脂成型品３ｂに押し込むことで化粧板１０は樹脂成型品３ｂに取り付けられるので、化粧板１０取付作業の能率も向上する。放熱パイプ８の偏平化のため放熱パイプ８を強く圧迫するにあたっては従来用いられたブチルゴム製のクッションは邪魔であり、それをなくすことができる。これにより部品コストを削減できる上、ブチルゴムを介さないで放熱パイプ８の熱が直接化粧板１０に伝えられることから、熱伝達効率も向上する。   Since the decorative board 10 is attached to the resin molded product 3b by pushing the decorative board 10 into the resin molded product 3b, the efficiency of the decorative board 10 attachment work is also improved. In order to flatten the heat radiating pipe 8, the conventionally used butyl rubber cushion is a hindrance when it is strongly pressed, and it can be eliminated. As a result, the component cost can be reduced, and the heat transfer efficiency is also improved because the heat of the heat radiating pipe 8 is directly transmitted to the decorative plate 10 without using butyl rubber.

爪片１２と凹陥孔１３は化粧板１０の長さ方向に沿って複数箇所に配置される。図５に示す通り、ここでは３箇所に配置されている。なお３箇所という数は単なる例示であり、発明を限定するものではない。このように複数箇所に係合部を設定するに際し、以下に述べる設計的配慮を施したものが実施形態２である。   The claw pieces 12 and the recessed holes 13 are arranged at a plurality of locations along the length direction of the decorative board 10. As shown in FIG. 5, it is arrange | positioned here at three places. The number of three places is merely an example and does not limit the invention. Thus, when setting an engaging part in several places, what gave the design consideration described below is Embodiment 2. FIG.

＜第２実施形態＞
第２実施形態では、複数の凹陥孔１３のうち、中央部の凹陥孔１３の左右に配置された凹陥孔１３は、中央部の凹陥孔１３に比べ、冷蔵庫１の奥寄りに配置されている。また樹脂成型品３ｂの前面は、化粧板１０の長さ方向において、扉６、７の方に向かって凸となるように僅かに湾曲している。このため、全ての爪片１２が自己に対応する凹陥孔１３に係合すると、それまで直線状であった化粧板１０は、その長さ方向を含む水平な平面内で、樹脂成型品３ｂの前面に沿うように曲げられる。すなわち化粧板１０は収納室の扉（冷凍室４の扉６及び冷蔵室５の扉７）に向かって凸となるように湾曲せしめられる。なお図５には扉の象徴としてドアキャップ６ｃが描かれている。 Second Embodiment
In the second embodiment, among the plurality of recessed holes 13, the recessed holes 13 disposed on the left and right sides of the central recessed hole 13 are disposed closer to the refrigerator 1 than the central recessed hole 13. . Further, the front surface of the resin molded product 3 b is slightly curved so as to be convex toward the doors 6 and 7 in the length direction of the decorative board 10. For this reason, when all the nail pieces 12 are engaged with the corresponding recessed holes 13, the decorative plate 10 that has been linear until then is formed in the horizontal plane including the length direction of the resin molded product 3 b. Bent along the front. That is, the decorative plate 10 is bent so as to protrude toward the doors of the storage room (the door 6 of the freezer room 4 and the door 7 of the refrigerator room 5). In FIG. 5, a door cap 6c is depicted as a symbol of the door.

上記のように化粧板１０を湾曲させるのは、ドアキャップ６ｃ、７ｃが湾曲しているからである。ドアキャップ６ｃ、７ｃには、扉６、７で断熱層を形成する発泡樹脂の収縮により、それらを化粧パネル６ａ、７ａの方に引き寄せようとする力が働く。ドアキャップ６ｃ、７ｃの中でも左右両端に位置する部位は発泡樹脂の収縮力に抗し得るが、ドアキャップ６ｃ、７ｃの中央部は収縮力に抗しきれず発泡樹脂の収縮に追随する。そのため、ドアキャップ６ｃ、７ｃは図５に示すように湾曲する。射出成型時にドアキャップ６ｃ、７ｃに生じる内部応力も、図５のような湾曲を生じさせる。   The decorative plate 10 is curved as described above because the door caps 6c and 7c are curved. The door caps 6c and 7c are subjected to a force to draw them toward the decorative panels 6a and 7a due to the shrinkage of the foamed resin that forms the heat insulating layer by the doors 6 and 7. Of the door caps 6c and 7c, the portions located at the left and right ends can withstand the contraction force of the foamed resin, but the central portions of the door caps 6c and 7c cannot resist the contraction force and follow the contraction of the foamed resin. Therefore, the door caps 6c and 7c are curved as shown in FIG. The internal stress generated in the door caps 6c and 7c at the time of injection molding also causes a curve as shown in FIG.

ドアキャップ６ｃ、７ｃが図５のように湾曲したにも関わらず、化粧板１０が直線状を保っていると、ドアキャップ６ｃ、７ｃの化粧板１０に対する間隔が、化粧板１０の中央部分だけ広くなる。化粧板１０との間隔が広ければ、その分だけドアパッキン６ｄ、７ｄが引き伸ばされないと磁石６ｅ、７ｅが十分化粧板１０に吸着しなくなる。冷凍室４及び冷蔵室５の冷気にさらされるドアパッキン６ｄ、７ｄは硬化しており、引き伸ばしが困難であることも多い。そのような時はドアパッキン６ｄ、７ｄと化粧板１０の間に隙間が生じ、冷凍室４内あるいは冷蔵室５内の冷気が化粧板１０に直接当たることがある。このような場合、化粧板１０の結露は避けられない。   Although the door caps 6c and 7c are curved as shown in FIG. Become wider. If the gap with the decorative plate 10 is wide, the magnets 6e and 7e are not sufficiently attracted to the decorative plate 10 unless the door packings 6d and 7d are stretched. The door packings 6d and 7d exposed to the cold air in the freezer compartment 4 and the refrigerator compartment 5 are hardened and are often difficult to stretch. In such a case, a gap is generated between the door packings 6d and 7d and the decorative plate 10, and cold air in the freezer compartment 4 or the refrigerator compartment 5 may directly hit the decorative plate 10. In such a case, condensation on the decorative board 10 is inevitable.

扉６、７に向かって凸となるように化粧板１０を湾曲させ、その湾曲の曲率を、化粧板１０とドアキャップ６ｃ、７ｃとの間隔がどの部位でもほぼ均等になるように設定しておけば、ドアパッキン６ｄ、７ｄによる気密保持をしっかりと維持することができる。これにより、放熱パイプ８による化粧板１０の防露効果が損なわれずに済む。   The decorative plate 10 is curved so as to be convex toward the doors 6 and 7, and the curvature of the curvature is set so that the interval between the decorative plate 10 and the door caps 6c and 7c is almost uniform at any part. If this is done, it is possible to securely maintain the airtightness of the door packings 6d and 7d. Thereby, the dew-proof effect of the decorative board 10 by the heat radiating pipe 8 is not impaired.

扉６、７に向かって凸となるように化粧板１０を湾曲させるにあたっては、樹脂成型品３ｂの前面の湾曲に化粧板１０を沿わせれば良いのであれば、係合部（爪片１２と凹陥孔１３）を左右２箇所に配置するだけでも目的を達成することができる。   When the decorative plate 10 is curved so as to be convex toward the doors 6 and 7, if the decorative plate 10 is to be aligned with the curvature of the front surface of the resin molded product 3b, the engaging portion (the nail piece 12 and The object can be achieved simply by disposing the recessed holes 13) at two locations on the left and right.

以上、本発明の実施形態につき説明したが、本発明の範囲はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で種々の変更を加えて実施することができる。   Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.
