Description

実施形態は、冷蔵庫に関する。   Embodiments relate to a refrigerator.

冷蔵庫は、その断熱性能の向上及び省エネルギー化を図るために、冷蔵庫本体となる断熱箱体を構成する外箱と内箱の間の空間に断熱材を挟み込んで構成されている。また、冷蔵庫の断熱箱体の開口部分を封止する扉も、外板と内板の間に断熱材を挟み込んで構成される。冷蔵庫は、断熱材として液状発泡断熱材が使用されたものが多いが、近年、液状発泡断熱材に代わって真空断熱材の使用が検討されている。例えば特許文献１では、冷蔵庫の扉に発泡ウレタンと真空断熱材とを併用した技術の提案が成されている。   In order to improve the heat insulation performance and save energy, the refrigerator is configured by sandwiching a heat insulating material in a space between an outer box and an inner box constituting a heat insulating box body serving as a refrigerator main body. Moreover, the door which seals the opening part of the heat insulation box of a refrigerator is also comprised by inserting a heat insulating material between an outer plate and an inner plate. Many refrigerators use liquid foam heat insulating materials as heat insulating materials, but in recent years, the use of vacuum heat insulating materials instead of liquid foam heat insulating materials has been studied. For example, Patent Document 1 proposes a technique in which urethane foam and a vacuum heat insulating material are used in combination on a refrigerator door.

真空断熱材は、コア材を薄い外包フィルムで真空パックした構成である。この真空断熱材は、発泡ウレタンよりも断熱性能に優れているが、外包フィルムが傷付きやすく、傷が付いて破損した場合には断熱性能が著しく落ちる。冷蔵庫の扉等で真空断熱材を使用する場合、取手の取付部分の螺子に触れる位置に真空断熱材を配置すると外包フィルムが破損するおそれがある。そこで、真空断熱材が螺子などと干渉しないようにサイズを小さくした場合、扉の内側に断熱材がない空間が増えるため、上記特許文献１のように発泡ウレタンなどを併用して断熱効果を高める必要がある。   A vacuum heat insulating material is the structure which vacuum-packed the core material with the thin envelope film. This vacuum heat insulating material is superior in heat insulating performance to foamed urethane, but the outer packaging film is easily damaged, and when it is damaged due to scratches, the heat insulating performance is remarkably reduced. When using a vacuum heat insulating material in a refrigerator door or the like, the outer packaging film may be damaged if the vacuum heat insulating material is disposed at a position where the handle touches the screw. Therefore, when the size is reduced so that the vacuum heat insulating material does not interfere with the screw or the like, the space without the heat insulating material increases on the inside of the door. There is a need.

以下、実施の形態を図に基づいて詳説する。   Hereinafter, embodiments will be described in detail with reference to the drawings.

（第１の実施形態）
図１及び図２に示すように、本実施形態における冷蔵庫１は、正面を開口とし、内側を複数の部屋に区画された断熱箱体３と、各部屋の正面側の開口を封止する複数の扉２１〜２６と、を備えている。 (First embodiment)
As shown in FIGS. 1 and 2, the refrigerator 1 in the present embodiment has a heat insulating box 3 whose front is an opening and the inside is partitioned into a plurality of rooms, and a plurality of openings that seal the front opening of each room. Doors 21-26.

断熱箱体３は、内箱と外箱との間に断熱材としてそれらの対向面のほぼ全面にＶＩＰ（Ｖａｃｕｕｍ Ｉｎｓｕｌａｔｉｏｎ Ｐａｎｅｌ）と呼ばれる真空断熱材３５を挟み込んで構成されている。尚、図２においては、説明のために冷蔵庫１の右側面板の真空断熱材３５のみを透過させて図示しているが、上面板、底面板、左側面板、背面板にも真空断熱材３５が配設されている。   The heat insulating box 3 is configured by sandwiching a vacuum heat insulating material 35 called VIP (Vacuum Insulation Panel) as a heat insulating material between the inner box and the outer box over almost the entire surface thereof. In FIG. 2, only the vacuum heat insulating material 35 on the right side plate of the refrigerator 1 is shown for the sake of explanation, but the vacuum heat insulating material 35 is also provided on the top plate, the bottom plate, the left side plate, and the back plate. It is arranged.

この断熱箱体３は、上方から順に冷蔵室１１と、野菜室１２と、横並びの製氷室１３及び第一冷凍室１４と、第二冷凍室１５の５個の部屋に区画されている。冷蔵室１１の正面側の開口には、観音開き式の冷蔵室第一扉２１と冷蔵室第二扉２２が取り付けられている。また、野菜室１２、製氷室１３、第一冷凍室１４、第二冷凍室１５の正面側の開口には、夫々引出し式の野菜室扉２３、製氷室扉２４、第一冷凍室扉２５、第二冷凍室扉２６が取り付けられている。   The heat insulation box 3 is partitioned into five rooms of a refrigerator compartment 11, a vegetable compartment 12, a side-by-side ice making room 13, a first freezer compartment 14, and a second freezer compartment 15 in order from the top. At the front opening of the refrigerating room 11, a double door refrigerating room first door 21 and a refrigerating room second door 22 are attached. In addition, in the opening on the front side of the vegetable room 12, the ice making room 13, the first freezing room 14, and the second freezing room 15, a drawer type vegetable room door 23, an ice making room door 24, a first freezing room door 25, respectively. A second freezer compartment door 26 is attached.

引出し式扉の構造を説明するため、代表して第二冷凍室扉２６について説明する。図３乃至図５に示すように、第二冷凍室扉２６は、外板３１と、内板３２と、内枠３３と、真空断熱材３５と、ガスケット３７と、取手３９とを備えている。尚、以下の説明においては、第二冷凍室扉２６における外板３１が位置する方向を前方、内板３２が位置する冷蔵庫１の内側方向を後方として述べる。   In order to explain the structure of the drawer-type door, the second freezer compartment door 26 will be described as a representative. As shown in FIGS. 3 to 5, the second freezer compartment door 26 includes an outer plate 31, an inner plate 32, an inner frame 33, a vacuum heat insulating material 35, a gasket 37, and a handle 39. . In the following description, the direction in which the outer plate 31 is located in the second freezer compartment door 26 will be described as the front, and the inner direction of the refrigerator 1 in which the inner plate 32 is located will be described as the rear.

第二冷凍室扉２６は、外板３１と内板３２の間に真空断熱材３５が挟み込まれている。そして、内板３２の後方から内板３２を外板３１に押し込むように内枠３３が外板３１に嵌合されている。内枠３３には、背面側に突出するスロート部３３ｂが設けられ、さらに、背面側（第二冷凍室扉２６における内側に位置する面）の外周近傍にガスケット３７が嵌着されている。また、外板３１の正面には取手３９が取り付けられている。   In the second freezer compartment door 26, a vacuum heat insulating material 35 is sandwiched between the outer plate 31 and the inner plate 32. The inner frame 33 is fitted to the outer plate 31 so as to push the inner plate 32 into the outer plate 31 from behind the inner plate 32. The inner frame 33 is provided with a throat portion 33b that protrudes toward the back side, and a gasket 37 is fitted near the outer periphery of the back side (the surface located inside the second freezer compartment door 26). A handle 39 is attached to the front surface of the outer plate 31.

外板３１は、略方形状の平面板である平板部３１ａと、平板部３１ａの外周縁から後方に延在する側壁３１ｂと、を備えた略箱形である。そして、平板部３１ａの上端近傍であって左右両端近傍には、取手３９が取り付けられる開口３１ｃが形成されている。   The outer plate 31 has a substantially box shape including a flat plate portion 31a, which is a substantially rectangular flat plate, and a side wall 31b extending rearward from the outer peripheral edge of the flat plate portion 31a. An opening 31c to which the handle 39 is attached is formed in the vicinity of the upper end of the flat plate portion 31a and in the vicinity of both left and right ends.

取手３９は、管状の中空もしくは中密な略コの字状の部材からなるグリップハンドルであり、外板３１の平板部３１ａと平行に延在する把持部３９ａと、把持部３９ａの両端から後方に延在する脚部３９ｂと、を備える。また、脚部３９ｂの後端部には凹部３９ｃが形成され、凹部３９ｃの底に位置する面（前面）には螺子４１が螺着されるねじ穴３９ｄが形成されている。   The handle 39 is a grip handle made of a tubular hollow or medium-sized substantially U-shaped member, and includes a gripping portion 39a extending in parallel with the flat plate portion 31a of the outer plate 31, and a rear side from both ends of the gripping portion 39a. And a leg portion 39b extending to the bottom. A concave portion 39c is formed at the rear end of the leg portion 39b, and a screw hole 39d into which the screw 41 is screwed is formed in a surface (front surface) located at the bottom of the concave portion 39c.

この取手３９は、取付部材としてのボス４０と螺子４１によって外板３１に固定されている。ボス４０は、リング部４０ａと、リング部４０ａの内径から前方に立ち上がる円筒部４０ｂと、円筒部４０ｂの前端面を塞ぐ円板状の当接部４０ｃと、当接部４０ｃに形成されたねじ穴４０ｄと、から成る。このボス４０は、リング部４０ａの前面（円筒部４０bが形成された側の面）に両面テープ等の接着部材が貼着され、円筒部４０bが外板３１の開口３１ｃを貫通した状態で外板３１に接着固定されている。そして、取手３９は、取手３９の凹部３９ｃをボス４０の円筒部４０ｂに被せた状態で螺子４１により固定されている。螺子４１は、ボス４０の円筒部４０ｂ内に入り込んだ状態となるため、外板３１の平板部３１ａよりも後方に螺子４１の頭が突出することはない。   The handle 39 is fixed to the outer plate 31 by a boss 40 and a screw 41 as mounting members. The boss 40 includes a ring part 40a, a cylindrical part 40b that rises forward from the inner diameter of the ring part 40a, a disk-like contact part 40c that closes the front end surface of the cylindrical part 40b, and a screw formed on the contact part 40c. A hole 40d. The boss 40 has an adhesive member such as a double-sided tape attached to the front surface (the surface on which the cylindrical portion 40b is formed) of the ring portion 40a, and the cylindrical portion 40b passes through the opening 31c of the outer plate 31 in an outer state. The plate 31 is adhesively fixed. The handle 39 is fixed by a screw 41 in a state where the concave portion 39 c of the handle 39 is covered with the cylindrical portion 40 b of the boss 40. Since the screw 41 enters the cylindrical portion 40 b of the boss 40, the head of the screw 41 does not protrude behind the flat plate portion 31 a of the outer plate 31.

真空断熱材３５は、外板３１の後面側の略全体にわたって配置されており、この真空断熱材３５の後面側に内板３２が配置されている。また、真空断熱材３５は外板３１に接着されており、ボス４０にも同様に接着されている。この真空断熱材３５は、コア材を外包フィルムで真空パックした構造であり、外包フィルムに突起物や螺子などが触れると破れることがある。本実施形態における冷蔵庫１の扉では、螺子４１の頭と真空断熱材３５の前面とが離間しているため、螺子４１によって真空断熱材３５の外包フィルムが破損することを防止できる。また、真空断熱材３５の側面には、スポンジテープなどのソフトテープ３６が巻装されている。このように側面にソフトテープ３６を巻装することで、外板３１と内板３２の連結部分やその他の部材から真空断熱材３５の外包フィルムを保護することができる。尚、真空断熱材３５は、外板３１だけでなく、必要な場合には内板３２にも接着されている。   The vacuum heat insulating material 35 is disposed over substantially the entire rear surface side of the outer plate 31, and the inner plate 32 is disposed on the rear surface side of the vacuum heat insulating material 35. Further, the vacuum heat insulating material 35 is bonded to the outer plate 31 and is also bonded to the boss 40 in the same manner. The vacuum heat insulating material 35 has a structure in which a core material is vacuum packed with an outer packaging film, and may be broken when a projection or a screw touches the outer packaging film. In the door of the refrigerator 1 in this embodiment, since the head of the screw 41 and the front surface of the vacuum heat insulating material 35 are separated from each other, the outer film of the vacuum heat insulating material 35 can be prevented from being damaged by the screw 41. A soft tape 36 such as a sponge tape is wound around the side surface of the vacuum heat insulating material 35. Thus, by winding the soft tape 36 on the side surface, the outer film of the vacuum heat insulating material 35 can be protected from the connection portion of the outer plate 31 and the inner plate 32 and other members. The vacuum heat insulating material 35 is bonded not only to the outer plate 31 but also to the inner plate 32 when necessary.

内枠３３は、方形状の枠体であり、外周縁近傍の後方にガスケット嵌合部３３ａとしての溝を備え、ガスケット嵌合部３３ａの内側にスロート部３３ｂを備えている。スロート部３３ｂの内部には発泡断熱材３３ｃが充填されている。そして、この内枠３３は、真空断熱材３５に接着された内板３２を外板３１の後面に押しつけるように配置され、外板３１の側壁３１ｂに嵌合されている。   The inner frame 33 is a rectangular frame, and includes a groove as a gasket fitting portion 33a behind the vicinity of the outer peripheral edge, and a throat portion 33b inside the gasket fitting portion 33a. The inside of the throat portion 33b is filled with a foam heat insulating material 33c. The inner frame 33 is disposed so as to press the inner plate 32 bonded to the vacuum heat insulating material 35 against the rear surface of the outer plate 31, and is fitted to the side wall 31 b of the outer plate 31.

ガスケット３７は、中空密閉のエアクッション部３７ａを有した枠体であり、矢尻状の差込部３７ｂを有している。さらに、ガスケット３７は、エアクッション部３７ａの後面に断熱箱体３の開口部周面に磁着するためのマグネット３７ｃを有している。このガスケット３７は柔軟材であり、差込部３７ｂを内枠３３のガスケット嵌合部３３ａに柔軟性を利用して押し込むことで内枠３３に取り付けられている。   The gasket 37 is a frame body having a hollow hermetically sealed air cushion portion 37a, and has an arrowhead-shaped insertion portion 37b. Furthermore, the gasket 37 has a magnet 37c for magnetically attaching to the peripheral surface of the opening of the heat insulating box 3 on the rear surface of the air cushion portion 37a. The gasket 37 is a flexible material, and is attached to the inner frame 33 by pushing the insertion portion 37b into the gasket fitting portion 33a of the inner frame 33 using flexibility.

このように本実施形態における扉では、外板３１の平板部３１ａと内板３２が平行に配置されているため、真空断熱材３５を第二冷凍室扉２６内の広い範囲に配置できることとなる。従来の冷蔵庫における扉では、取手が上端面と連続して形成された構造のものがあり、このような形状の扉では取手を掴みやすくするために外板における取手の近傍部分（上端近傍部分）が後方（扉の内側）に入り込んだ形状とされることがあった。この場合、外板と内板との距離、すなわち扉の厚みが一定でないため、平板形状の真空断熱材を扉の内側に配置しても真空断熱材が存在しない空間が広く存在することとなる。しかし、本実施形態では、外板３１の前端面（平板部３１ａ）が平板形状であるため、外板３１の平板部３１ａと内板３２を平行に配置すると、平板形状の真空断熱材３５を扉内の広い範囲、略全体に配置できることとなる。   Thus, in the door in this embodiment, since the flat plate portion 31a of the outer plate 31 and the inner plate 32 are arranged in parallel, the vacuum heat insulating material 35 can be arranged in a wide range in the second freezer compartment door 26. . Some doors in conventional refrigerators have a structure in which the handle is formed continuously with the upper end surface. In the door with such a shape, the vicinity of the handle on the outer plate (the vicinity of the upper end) in order to make it easier to grip the handle. May have a shape that entered the back (inside the door). In this case, since the distance between the outer plate and the inner plate, that is, the thickness of the door is not constant, there is a wide space where no vacuum heat insulating material exists even if a flat plate vacuum heat insulating material is arranged inside the door. . However, in this embodiment, since the front end surface (flat plate portion 31a) of the outer plate 31 has a flat plate shape, when the flat plate portion 31a of the outer plate 31 and the inner plate 32 are arranged in parallel, the flat plate-shaped vacuum heat insulating material 35 is provided. It can be arranged over a wide range in the door, almost the whole.

尚、外板３１を平板部３１ａと側壁３１ｂとからなる箱形形状として説明しているが、外板３１を平板として外板３１と内枠３３を側面板などで連結する構成としてもよい。すなわち、本実施形態における扉は、少なくとも平板部分を備えた外板３１と内板３２を有し、外板３１の平板部分と内板３２が平板形状の真空断熱材３５を挟み込むように平行に配置されていればよい。   Although the outer plate 31 is described as a box-shaped shape including a flat plate portion 31a and a side wall 31b, the outer plate 31 may be a flat plate and the outer plate 31 and the inner frame 33 may be connected by a side plate or the like. That is, the door in the present embodiment has an outer plate 31 and an inner plate 32 having at least a flat plate portion, and the flat plate portion of the outer plate 31 and the inner plate 32 are parallel so as to sandwich the flat plate-shaped vacuum heat insulating material 35. It only has to be arranged.

また、本実施形態における扉では、取手３９がグリップハンドルとされている。すなわち、扉の上端面から前方に突出した形状ではなく、外板３１から把持部３９ａ（グリップ部）が離間した形状であるため、外板３１に指などをかけやすくするための凹部や溝を設ける必要がなく外板３１を平板状に形成できる。   Moreover, in the door in this embodiment, the handle 39 is a grip handle. That is, it is not a shape protruding forward from the upper end surface of the door, but a shape in which the grip portion 39a (grip portion) is separated from the outer plate 31, so that a recess or a groove for easily placing a finger or the like on the outer plate 31 is provided. There is no need to provide the outer plate 31, and the outer plate 31 can be formed in a flat plate shape.

さらに、取手３９を外板３１に取り付けた状態においては、螺子４１の頭と真空断熱材３５とが離間した状態となるため、真空断熱材３５を螺子４１の頭等で傷つけることも防止できる。   Further, when the handle 39 is attached to the outer plate 31, the head of the screw 41 and the vacuum heat insulating material 35 are separated from each other, so that the vacuum heat insulating material 35 can be prevented from being damaged by the head of the screw 41 or the like.

尚、引出し式扉として第二冷凍室扉２６を例に取って述べたが、観音式扉または回転式扉の取手にも同様の構成を用いることができる。   In addition, although the 2nd freezer compartment door 26 was taken and described as an example as a drawer-type door, the same structure can be used also for the handle of a kannon door or a rotary door.

（第２の実施形態）
次に、第２の実施形態について説明する。尚、以下の実施形態においても、共通する部位に関しては共通する符号を用いて説明する。図６〜図８に示すように、本実施形態における冷蔵室第一扉２１は、第１の実施形態と同様に外板３１と内板３２との間に真空断熱材３５を挟み込んでなり、外板３１には取手３９が取り付けられている。そして、真空断熱材３５は、取手３９の取付部に対応する位置（本実施形態においては上方の隣接する角部）が三角形状に切り欠いて形成されている。すなわち、取手３９の取付部の直下には真空断熱材３５が配置されておらず、代わりに発泡ウレタン等の発泡断熱材４５やその他の断熱材が充填されている。 (Second Embodiment)
Next, a second embodiment will be described. In the following embodiments, common portions will be described using common reference numerals. As shown in FIGS. 6-8, the refrigerator door 1st door 21 in this embodiment inserts the vacuum heat insulating material 35 between the outer plate 31 and the inner plate 32 similarly to 1st Embodiment, A handle 39 is attached to the outer plate 31. And the vacuum heat insulating material 35 is formed by notching the position corresponding to the attachment part of the handle 39 (in this embodiment, the upper adjacent corner part) into a triangular shape. That is, the vacuum heat insulating material 35 is not disposed directly under the attachment portion of the handle 39, but instead is filled with a foam heat insulating material 45 such as urethane foam and other heat insulating materials.

このように、真空断熱材３５を上部両端を三角形状に切り欠いた形状にし、取手３９の取付部の直下には真空断熱材３５が配置されていない空間を形成することで、取付部材と真空断熱材３５を離間させることができ、取手３９の取付部材（ボス４０や螺子４１）が真空断熱材３５に接触して真空断熱材３５のフィルムが破損することを防止できる。尚、取手３９や取手３９の取付部材、その他の構成は第１の実施形態と共通であり、作用や効果も同一であるが、取手３９の取付部近傍に真空断熱材が配置されていないため、図９に示すように、螺子４１の頭が扉内に突出する構成としてもよい。図９においては、取付部材としてのボス４０を使用しておらず、中密な取手３９の脚部３９ｂに螺子４１で直接取り付ける構成とされている。   Thus, the vacuum heat insulating material 35 is formed in a shape in which both upper ends are cut out in a triangular shape, and a space in which the vacuum heat insulating material 35 is not disposed is formed immediately below the mounting portion of the handle 39, so that the mounting member and the vacuum are formed. The heat insulating material 35 can be separated, and the attachment member (boss 40 or screw 41) of the handle 39 can be prevented from coming into contact with the vacuum heat insulating material 35 and damaging the film of the vacuum heat insulating material 35. The handle 39, the attachment member of the handle 39, and other configurations are the same as those of the first embodiment, and the operation and effect are the same. However, no vacuum heat insulating material is disposed in the vicinity of the attachment portion of the handle 39. As shown in FIG. 9, the head of the screw 41 may be configured to protrude into the door. In FIG. 9, the boss 40 as an attachment member is not used, and the structure is such that the screw 41 directly attaches to the leg portion 39 b of the medium handle 39.

本発明のいくつかの実施形態を説明したが、これらの実施形態は、例として提示したものであり、発明の範囲を限定することは意図していない。これら新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。これら実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。例えば、発泡断熱材としては発泡ウレタンに限らず、発泡スチロール、発泡ポリプロピレン等を採用することができる。また外板、内板に対する真空断熱材の接着には、ホットメルト接着剤や、両面テープ、フィルム状接着剤等による接着技術を採用することができる。   Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof. For example, the foam heat insulating material is not limited to urethane foam, but may be foamed polystyrene, foamed polypropylene, or the like. For bonding the vacuum heat insulating material to the outer plate and the inner plate, a bonding technique using a hot melt adhesive, a double-sided tape, a film adhesive, or the like can be employed.
