Description

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

冷蔵庫は、断熱性能を向上するために、外壁部および扉等の内部に真空断熱材を設けるとともに、この真空断熱材を設けた隙間に発泡断熱材である発泡ウレタンを充填して、断熱性能の向上を図っているが、例えば冷蔵庫の扉においては、扉の表面積に比較して真空断熱材の表面積の割合が少ないとともに、この真空断熱材のない部分には発泡ウレタンを厚く設けて、断熱性能の向上を図っている。しかしながら、発泡ウレタンを厚く設けることにより、発泡ウレタンの厚さの分だけ、扉が厚くなって、冷蔵庫の内部の奥行きが小さくなり、冷蔵庫の内容積が小さくなっている。 In the refrigerator, in order to improve the heat insulating performance, a vacuum heat insulating material is provided inside the outer wall and the door, and the gap provided with the vacuum heat insulating material is filled with urethane foam, which is a foam heat insulating material, to improve the heat insulating performance. Although we are trying to improve it, for example, in the refrigerator door, the ratio of the surface area of the vacuum heat insulating material is smaller than the surface area of the door, and the heat insulating performance is provided by thickly providing urethane foam in the part without the vacuum heat insulating material. We are trying to improve. However, by providing the urethane foam thickly, the door becomes thicker by the thickness of the urethane foam, the depth inside the refrigerator becomes smaller, and the internal volume of the refrigerator becomes smaller.

一方、冷蔵庫の扉の表面には、冷蔵庫の動作状態を制御したり、表示するための例えば操作ボタンや表示器などからなる操作部を設けているが、この操作部を設けるために扉の表面の一部を凹ませたり、孔をあけるなどしている。従って、この凹ませられたり、孔をあけられた扉の裏側には、真空断熱材を設けることができないため、発泡ウレタンを厚く充填している。このため、扉は更に厚くなり、上述したように発泡ウレタンの厚さの分だけ、冷蔵庫の内部の奥行きが小さくなり、冷蔵庫の内容積が小さくなっている。 On the other hand, the surface of the refrigerator door is provided with an operation unit including, for example, operation buttons and a display for controlling and displaying the operating state of the refrigerator. In order to provide this operation unit, the surface of the door is provided. A part of the door is dented or a hole is made. Therefore, since the vacuum heat insulating material cannot be provided on the back side of the dented or perforated door, urethane foam is thickly filled. Therefore, the door becomes thicker, and as described above, the depth inside the refrigerator becomes smaller by the thickness of the urethane foam, and the internal volume of the refrigerator becomes smaller.

従って、扉に操作部を設けても、扉を薄くでき、断熱性能が低下しない冷蔵庫を要望されている。 Therefore, there is a demand for a refrigerator that can make the door thinner and does not deteriorate the heat insulating performance even if the operation unit is provided on the door.

特開２００４－３４７２１６号公報Japanese Unexamined Patent Publication No. 2004-347216

以下、図面を用いて、本発明を実施するための形態(以下、実施形態と称する)を説明する。 Hereinafter, embodiments for carrying out the present invention (hereinafter referred to as embodiments) will be described with reference to the drawings.

図１は、本発明の第１の実施形態に係わる冷蔵庫の全体構成を示す斜視図である。同図に示す冷蔵庫１は、最上部に冷蔵室３が設けられ、この冷蔵室３は右端部に図示しないヒンジが取り付けられ、この右端を軸として開閉する片開き式の扉５が取り付けられている。この冷蔵室３の扉５のヒンジ側とは反対の左側の自由端部の表面には、取っ手であるハンドル７が取り付けられ、このハンドル７には、冷蔵庫１の各部の動作状態を制御したり、表示するための例えば操作ボタンや表示器などからなる機能手段でもある操作部９が設けられている。この機能手段は、動作状態等を表示する表示部と、この表示を制御する制御部、そして動作状態を制御するための操作ボタン部と、この操作ボタン部での操作を処理し、制御する制御部からなるが、これらは一体であっても、後述するように個々に別体であっても、機能の一部のみを一体に設けていても構わない。 FIG. 1 is a perspective view showing the overall configuration of a refrigerator according to the first embodiment of the present invention. The refrigerator 1 shown in the figure is provided with a refrigerating chamber 3 at the uppermost portion, and a hinge (not shown) is attached to the right end portion of the refrigerating chamber 3, and a single door 5 that opens and closes around the right end is attached. There is. A handle 7 as a handle is attached to the surface of the free end portion on the left side opposite to the hinge side of the door 5 of the refrigerator compartment 3, and the handle 7 controls the operating state of each part of the refrigerator 1. , An operation unit 9 which is also a functional means including, for example, an operation button and a display for displaying is provided. This functional means has a display unit that displays an operating state and the like, a control unit that controls this display, an operation button unit that controls the operating state, and a control that processes and controls operations on the operation button unit. Although they are composed of parts, they may be integrated, they may be individually separated as described later, or only a part of the function may be provided integrally.

なお、冷蔵庫１は、冷蔵室３の下側に野菜室１１が設けられ、この野菜室１１の真下に製氷室１３と冷蔵から冷凍までの任意の冷却状態に可変し得る切替室とも称する上部冷凍室１５が横に並んで設けられ、これら製氷室１３と上部冷凍室１５の直下の最下部には冷凍室１７が設けられている。 The refrigerator 1 is provided with a vegetable compartment 11 under the refrigerating chamber 3, and directly below the vegetable compartment 11 is an ice making chamber 13 and an upper freezing chamber, which is also called a switching chamber that can be changed to an arbitrary cooling state from refrigeration to freezing. The chambers 15 are provided side by side, and a freezing chamber 17 is provided at the lowermost part directly below the ice making chamber 13 and the upper freezing chamber 15.

図２は、図１に示した冷蔵庫１の冷蔵室３の扉５のみを示す正面図である。図２に示すように、扉５の左端の自由端部寄りには、ハンドル７が取り付けられ、このハンドル７に操作部９が設けられているが、更に扉５の上下両端には、扉上キャップ２１および扉下キャップ２３が取り付けられている。 FIG. 2 is a front view showing only the door 5 of the refrigerating chamber 3 of the refrigerator 1 shown in FIG. As shown in FIG. 2, a handle 7 is attached near the free end of the left end of the door 5, and an operation unit 9 is provided on the handle 7, but further, on the upper and lower ends of the door 5, on the door. A cap 21 and a cap 23 under the door are attached.

図３は、図２に示した扉５の分解斜視図である。図３に示すように、扉５は、その前側を全体的に覆う前板である面材２５を有し、この面材２５の左右両側部は、扉５内に実装される各部材を両側から囲んで固定するように後方に折り曲がってから、更に内側に少し折曲している。そして、この面材２５の上下両端には、前記扉上キャップ２１および扉下キャップ２３が嵌合するようになっている。 FIG. 3 is an exploded perspective view of the door 5 shown in FIG. As shown in FIG. 3, the door 5 has a face material 25 which is a front plate that totally covers the front side thereof, and the left and right side portions of the face material 25 have both sides of each member mounted in the door 5. It is bent backwards so that it is surrounded and fixed, and then slightly bent inward. The upper door cap 21 and the lower door cap 23 are fitted to the upper and lower ends of the face material 25.

なお、操作部９の設けられたハンドル７の上下両端は、４本の皿ねじ１９で面材２５に固定されているが、この皿ねじ１９によるハンドル７の面材２５への固定は、詳しくは、図５に断面を示すように、皿ねじ１９の頭部が前記面材２５よりも突出しないように面材２５に円錐状の孔を形成し、この円錐状の孔内に皿ねじ１９の頭部が入って面材２５よりも突出しないようにしている。これは、後述するように、面材２５の裏側に真空断熱材を接着剤で貼り付けた時に皿ねじ１９の頭部で真空断熱材に傷がつくことを防止するためである。なお、図５は、図２の線ｂ－ｂに沿った断面である。 The upper and lower ends of the handle 7 provided with the operation unit 9 are fixed to the face material 25 with four countersunk screws 19, but the fixing of the handle 7 to the face material 25 by the countersunk screws 19 is detailed. As shown in the cross section in FIG. 5, a conical hole is formed in the face material 25 so that the head of the countersunk screw 19 does not protrude from the face material 25, and the countersunk screw 19 is formed in the conical hole. The head of the head is inserted so that it does not protrude from the face material 25. This is to prevent the vacuum heat insulating material from being damaged by the head of the countersunk screw 19 when the vacuum heat insulating material is attached to the back side of the face material 25 with an adhesive, as will be described later. Note that FIG. 5 is a cross section taken along the line bb of FIG.

図３に戻って、前記面材２５の後方には、矩形の真空断熱材２７が設けられ、この真空断熱材２７が接着剤で面材２５の裏面に貼り付けられるようになっている。なお、この真空断熱材２７の周囲には、真空断熱材と異なる断熱材であって、真空断熱材よりも断熱性能が低いが配設する場所の形状に合わせて成形しやすい別の例えば発泡スチロール（ＥＰＳ）などからなる成形品である発泡断熱材２９ａ、２９ｂ、２９ｃ、２９ｄが真空断熱材２７を四方から囲むように近接して設けられている。 Returning to FIG. 3, a rectangular vacuum heat insulating material 27 is provided behind the face material 25, and the vacuum heat insulating material 27 is attached to the back surface of the face material 25 with an adhesive. Around the vacuum heat insulating material 27, another heat insulating material different from the vacuum heat insulating material, for example, foamed styrene (which has lower heat insulating performance than the vacuum heat insulating material but is easy to mold according to the shape of the place where the vacuum heat insulating material is arranged) ( Foam heat insulating materials 29a, 29b, 29c, 29d, which are molded products made of EPS) and the like, are provided in close proximity so as to surround the vacuum heat insulating material 27 from all sides.

また、真空断熱材２７および発泡断熱材２９ａ、２９ｂ、２９ｃ、２９ｄの後方には、扉５の裏側を全体的に覆う裏板である扉内側部３１が設けられているが、この扉内側部３１の四方の周辺寄りの全周縁部分は、冷蔵室３の内側に向かって断面が細い台形状に突出して、スロート部３３を細長く形成している。また、このスロート部３３の外側は、僅かに外方に延出し、この延出した部分に後方に図示されている矩形の枠状のガスケット３５が装着されるようになっている。詳しくは、前記延出した部分には図示しない凹部が形成され、この凹部にガスケット３５の矢尻状の差込部が差し込まれて、これによりガスケット３５が扉内側部３１に装着されている。 Further, behind the vacuum heat insulating material 27 and the foam heat insulating materials 29a, 29b, 29c, 29d, a door inner portion 31 which is a back plate that totally covers the back side of the door 5 is provided, and the door inner portion 31 is provided. The entire peripheral edge portion of the 31 on all sides near the periphery protrudes in a trapezoidal shape having a narrow cross section toward the inside of the refrigerating chamber 3, and forms the throat portion 33 in an elongated shape. Further, the outside of the throat portion 33 is slightly extended outward, and a rectangular frame-shaped gasket 35 shown in the rear is attached to the extended portion. Specifically, a recess (not shown) is formed in the extended portion, and an arrowhead-shaped insertion portion of the gasket 35 is inserted into the recess, whereby the gasket 35 is attached to the door inner portion 31.

図４は、図２に示した扉５において線ａ―ａに沿って切断した扉５の左端部寄りの部分のみを拡大して示す断面図である。図４に示すように、前記面材２５の裏側には、真空断熱材２７が接着により貼り付けられ、この真空断熱材２７の反対側の裏面には、裏板を構成する前記扉内側部３１が接着により貼り付けられている。また、操作部９を有するハンドル７が面材２５の左端寄りの表面に図５で説明したように皿ねじ１９により取り付けられている。このハンドル７が取り付けられた面材２５の内側には、ＥＰＳからなる前記発泡断熱材２９ｂが配設され、この発泡断熱材２９ｂと真空断熱材２７との間に同様にスポンジやＥＰＳなどからなる発泡断熱材３７が配設されている。また、裏板を構成する扉内側部３１は、端部寄りの部分が冷蔵室３内に向かって大きく膨出して、前記スロート部３３を形成し、このスロート部３３内には同様にＥＰＳなどからなる発泡断熱材４１が配設されている。 FIG. 4 is an enlarged cross-sectional view showing only a portion of the door 5 shown in FIG. 2 near the left end portion of the door 5 cut along the line aa. As shown in FIG. 4, a vacuum heat insulating material 27 is adhered to the back side of the face material 25 by adhesion, and the door inner portion 31 constituting the back plate is attached to the back surface on the opposite side of the vacuum heat insulating material 27. Is attached by adhesion. Further, the handle 7 having the operation portion 9 is attached to the surface of the face material 25 near the left end by a countersunk screw 19 as described with reference to FIG. The foamed heat insulating material 29b made of EPS is arranged inside the face material 25 to which the handle 7 is attached, and similarly made of a sponge, EPS or the like between the foamed heat insulating material 29b and the vacuum heat insulating material 27. The foam heat insulating material 37 is arranged. Further, in the door inner portion 31 constituting the back plate, a portion near the end portion greatly bulges toward the inside of the refrigerating chamber 3 to form the throat portion 33, and an EPS or the like is similarly formed in the throat portion 33. A foamed heat insulating material 41 made of the same material is arranged.

発泡断熱材２９ｂの裏側であって、発泡断熱材３７の横には、ガスケット３５の差込部３５ａが挿入される凹部３９が形成されている。この凹部３９に差し込まれた差込部３５ａに続くガスケット３５のエアクッション部３５ｂは、凹部３９から突出し、図示しない冷蔵庫１の側壁の端部に当接し、冷蔵庫１を密閉状態に閉塞するようになっているが、このエアクッション部３５ｂの背面には、マグネット３５ｃが取り付けられ、このマグネット３５ｃにより冷蔵庫１の側壁の端部の金属部などに磁気的に吸着し、扉５を完全に閉塞するようになっている。 On the back side of the foamed heat insulating material 29b, a recess 39 into which the insertion portion 35a of the gasket 35 is inserted is formed next to the foamed heat insulating material 37. The air cushion portion 35b of the gasket 35 following the insertion portion 35a inserted into the recess 39 protrudes from the recess 39 and abuts on the end of the side wall of the refrigerator 1 (not shown) so as to close the refrigerator 1 in a sealed state. However, a magnet 35c is attached to the back surface of the air cushion portion 35b, and the magnet 35c magnetically attracts the metal portion at the end of the side wall of the refrigerator 1 to completely close the door 5. It has become like.

更に、前記発泡断熱材２９ｂの裏側であって、扉５の左端部の内側には、操作部９の制御部を構成する電気部品を実装した基板４３が配設されている。 Further, on the back side of the foamed heat insulating material 29b, inside the left end portion of the door 5, a substrate 43 on which electrical components constituting the control unit of the operation unit 9 are mounted is disposed.

以上のように構成される本実施形態の冷蔵庫１においては、操作部９は、扉５から突出したハンドル７に設けられていて、真空断熱材２７が配設される扉５の表面などに設けられていないため、扉５の表面を構成する面材２５に操作部のための凹部や孔などがなく、このため真空断熱材２７を扉５のほぼ全面にわたって広く設けることができ、扉５の断熱性能を向上できるとともに、薄くても断熱性能の良好な真空断熱材２７を使用することで扉５自身も薄くでき、ひいては冷蔵室３の内容量を増大することができる。 In the refrigerator 1 of the present embodiment configured as described above, the operation unit 9 is provided on the handle 7 protruding from the door 5, and is provided on the surface of the door 5 on which the vacuum heat insulating material 27 is arranged. Since the surface material 25 constituting the surface of the door 5 does not have recesses or holes for the operation portion, the vacuum heat insulating material 27 can be widely provided over almost the entire surface of the door 5, and the door 5 can be provided. By using the vacuum heat insulating material 27 which is thin but has good heat insulating performance, the door 5 itself can be made thin, and the internal capacity of the refrigerating chamber 3 can be increased.

また、操作部９は、ハンドル７に設けられているものであるため、外観的にも良好である上に、冷蔵庫１を使用する時にハンドル７を操作しながら操作部９を見ることができ、操作性を向上することができるとともに、手の移動や視線の移動を少なくすることもできる。なお、ハンドル７は、皿ねじ１９により面材２５の内側から取り付けられ、面材２５の裏側に皿ねじ１９が突出することがないため、真空断熱材２７が皿ねじ１９で傷つくこともない。 Further, since the operation unit 9 is provided on the handle 7, the appearance is also good, and when using the refrigerator 1, the operation unit 9 can be seen while operating the handle 7. The operability can be improved, and the movement of the hand and the movement of the line of sight can be reduced. Since the handle 7 is attached from the inside of the face material 25 by the countersunk screw 19 and the countersunk screw 19 does not protrude from the back side of the face material 25, the vacuum heat insulating material 27 is not damaged by the countersunk screw 19.

更に、操作部９の取り付けのために、冷蔵室３の扉５の表面などに凹部や孔などを形成する必要がないため、操作部９のない汎用的な扉として扉５を標準化でき、操作部９の表示器や操作ボタンなどを変更するだけで、種々の冷蔵庫に適用することができる。 Further, since it is not necessary to form recesses or holes on the surface of the door 5 of the refrigerator compartment 3 for mounting the operation unit 9, the door 5 can be standardized as a general-purpose door without the operation unit 9 and operated. It can be applied to various refrigerators only by changing the display and operation buttons of the unit 9.

また、扉５の端部には、真空断熱材２７の端部に対して発泡断熱材３７を挟んで発泡断熱材２９ｂを設けているため、真空断熱材２７の端部が長さ的にばらついても、この真空断熱材２７のばらつきを発泡断熱材３７および発泡断熱材２９ｂで吸収することができる。 Further, since the foam heat insulating material 29b is provided at the end of the door 5 with the foam heat insulating material 37 sandwiched between the end of the vacuum heat insulating material 27, the end of the vacuum heat insulating material 27 varies in length. However, the variation of the vacuum heat insulating material 27 can be absorbed by the foam heat insulating material 37 and the foam heat insulating material 29b.

なお、本実施形態では、操作部９をハンドル７に設けた場合について説明したが、本発明は、これに限定されるものでなく、真空断熱材２７を取り付ける面材２５に凹部や孔を作ることなく、真空断熱材２７を扉５のほぼ全面にわたって広く設けることができればよいものである。 In the present embodiment, the case where the operation unit 9 is provided on the handle 7 has been described, but the present invention is not limited to this, and recesses and holes are formed in the face material 25 to which the vacuum heat insulating material 27 is attached. It suffices if the vacuum heat insulating material 27 can be widely provided over almost the entire surface of the door 5.

図６は、本発明の第２の実施形態に係わる冷蔵庫に適用される扉の左端部分の断面を示す断面図である。なお、この図６に示す扉５０は、図１乃至図５に示した第１の実施形態において操作部９の制御部を構成する電気部品を実装した基板の位置およびこの基板に隣接する発泡断熱材の形状が異なるのみであり、その他の構成作用は図１乃至図５に示した冷蔵庫１および扉５と同じであり、同じ構成要素には同じ符号を付し、その説明を省略する。 FIG. 6 is a cross-sectional view showing a cross section of a left end portion of a door applied to a refrigerator according to a second embodiment of the present invention. The door 50 shown in FIG. 6 is the position of the substrate on which the electric components constituting the control unit of the operation unit 9 are mounted in the first embodiment shown in FIGS. 1 to 5, and the foam insulation adjacent to the substrate. Only the shape of the material is different, and other constituent actions are the same as those of the refrigerator 1 and the door 5 shown in FIGS. 1 to 5. The same constituent elements are designated by the same reference numerals, and the description thereof will be omitted.

すなわち、図６に示す扉５０は、第１の実施形態と同様に、面材２５の裏面には、真空断熱材２７が接着により貼り付けられ、この真空断熱材２７の裏側には扉内側部３１が貼り付けられ、この扉内側部３１の端部寄りの部分にはスロート部３３が形成され、このスロート部３３の内部に発泡断熱材４１が配設されるとともに、面材２５の左端部寄りの表面には、ハンドル７が取り付けられ、このハンドル７に操作部９が設けられている。 That is, in the door 50 shown in FIG. 6, the vacuum heat insulating material 27 is adhered to the back surface of the face material 25 by adhesion as in the first embodiment, and the inside of the door is attached to the back side of the vacuum heat insulating material 27. 31 is attached, a throat portion 33 is formed in a portion near the end of the door inner portion 31, a foam heat insulating material 41 is disposed inside the throat portion 33, and the left end portion of the face material 25 is provided. A handle 7 is attached to the surface closer to the handle 7, and an operation unit 9 is provided on the handle 7.

また同様に、真空断熱材２７の端部には、発泡断熱材３７が隣接して設けられ、この発泡断熱材３７に隣接して凹部３９が形成され、この凹部３９にガスケット３５の差込部３５ａが差し込まれ、ガスケット３５のエアクッション部３５ｂにはマグネット３５ｃが内側に設けられ、このマグネット３５ｃは、冷蔵室３を構成する側壁５１の端面を構成している金属部などに磁気的に吸着し、扉５０を完全に閉塞するようになっている。 Similarly, a foam heat insulating material 37 is provided adjacent to the end of the vacuum heat insulating material 27, a recess 39 is formed adjacent to the foam heat insulating material 37, and a gasket 35 is inserted into the recess 39. 35a is inserted, and a magnet 35c is provided inside the air cushion portion 35b of the gasket 35, and the magnet 35c is magnetically attracted to a metal portion or the like constituting the end surface of the side wall 51 constituting the refrigerating chamber 3. However, the door 50 is completely closed.

このような構成において、本第２の実施形態の扉５０においては、操作部９の制御部を構成する電気部品を実装した基板は、符号４３０で示すように扉５０の左端に設けられているが、この基板４３０と前記発泡断熱材３７との間に設けられている発泡断熱材は、符号２９０で示すように、図６で上端部が左方に延出し、この延出部２９０ａで基板４３０の上部を囲むように形成されている。また、基板４３０の電気部品などの実装された面は、発泡断熱材２９０の図６で上方に伸びた面に平行に配設され、発泡断熱材２９０で覆われるようになっている。すなわち、発泡断熱材２９０は、基板４３０の上部および右側面を覆って断熱するように構成されている。 In such a configuration, in the door 50 of the second embodiment, the substrate on which the electric components constituting the control unit of the operation unit 9 are mounted is provided at the left end of the door 50 as shown by reference numeral 430. However, as shown by reference numeral 290, the foamed heat insulating material provided between the substrate 430 and the foamed heat insulating material 37 has an upper end portion extending to the left in FIG. 6, and the extending portion 290a serves as a substrate. It is formed so as to surround the upper part of the 430. Further, the mounted surface of the substrate 430 such as an electric component is arranged in parallel with the surface of the foamed heat insulating material 290 extending upward in FIG. 6, and is covered with the foamed heat insulating material 290.
