Description

本発明は、真空断熱材を有する断熱扉及びそれを用いた貯蔵庫に関する。   The present invention relates to a heat insulating door having a vacuum heat insulating material and a storage using the same.

冷蔵庫等の貯蔵庫の開口部を開閉する従来の断熱扉は特許文献１に開示されている。この断熱扉は内部に真空断熱材が配されるとともに、発泡ウレタン等の発泡断熱材が充填されている。真空断熱材は袋状の外装材内にガラス繊維等の芯材を内包し、外装材は内部を真空に維持して端部を密着した密着部により密閉されている。これにより、断熱扉が高い断熱効果を得ることができる。   A conventional heat insulating door that opens and closes an opening of a storage such as a refrigerator is disclosed in Patent Document 1. The heat insulating door is provided with a vacuum heat insulating material and filled with a foam heat insulating material such as urethane foam. The vacuum heat insulating material encloses a core material such as glass fiber in a bag-shaped exterior material, and the exterior material is hermetically sealed by a close contact portion in which the inside is kept in a vacuum and the ends are in close contact. Thereby, the heat insulation door can acquire the high heat insulation effect.

上記の断熱扉によると、発泡断熱材が発泡する際に開放端が支持されていない密着部により流動が妨げられ、発泡断熱材が充填されない空間部が生じる。このため、密着部の開放端を固定した断熱扉が知られている。図９はこの断熱扉の概略を示す横断面図である。また、図１０は図９のＢ−Ｂ断面図を示しており、図１１は真空断熱材の平面図を示している。   According to said heat insulation door, when a foaming heat insulating material foams, a flow part is prevented by the contact | adherence part by which the open end is not supported, and the space part which is not filled with a foaming heat insulating material arises. For this reason, the heat insulation door which fixed the open end of the contact | adherence part is known. FIG. 9 is a cross-sectional view showing the outline of the heat insulating door. FIG. 10 shows a cross-sectional view along the line BB in FIG. 9, and FIG. 11 shows a plan view of the vacuum heat insulating material.

断熱扉１１は貯蔵庫の外面に面した外板成型品２３と内面に面した内板成型品２２とが対向配置される。内板成型品２２の裏面には真空断熱材２４が両面粘着テープ２５により固着され、外板成型品２３と内板成型品２２との間には真空断熱材２４に接して発泡断熱材２６が充填されている。内板成型品２２は貯蔵庫側に突出した突出部２２ａを有し、空気や発泡断熱材２６の発泡時に発生するガスを排気する排気孔２２ｂが突出部２２ａの先端に設けられる。   The heat insulation door 11 has an outer plate molded product 23 facing the outer surface of the storage and an inner plate molded product 22 facing the inner surface. A vacuum heat insulating material 24 is fixed to the back surface of the inner plate molded product 22 by a double-sided adhesive tape 25, and a foam heat insulating material 26 is in contact with the vacuum heat insulating material 24 between the outer plate molded product 23 and the inner plate molded product 22. Filled. The inner plate molded product 22 has a protruding portion 22a protruding toward the storage side, and an exhaust hole 22b for exhausting air or gas generated when foaming the foam heat insulating material 26 is provided at the tip of the protruding portion 22a.

真空断熱材２４は外装材２４ａの一端が密着部２４ｃで密着され、密着部２４ｃは内板成型品２２側に折り返されて所定間隔で配される粘着テープ２７により開放端が外装材２４ａに貼着されている。これにより、密着部２４ｃによって発泡断熱材２６の流動が妨げられることを防止できるようになっている。
特開２００５−１６７７６号公報（第３頁−第４頁、第１図） The vacuum heat insulating material 24 has one end of the exterior material 24a in close contact with the contact portion 24c, and the close contact portion 24c is folded back to the inner plate molded product 22 side and attached to the exterior material 24a by an adhesive tape 27 disposed at a predetermined interval. It is worn. Thereby, it can prevent that the flow of the foam heat insulating material 26 is prevented by the contact | adherence part 24c.
Japanese Patent Laying-Open No. 2005-16776 (page 3 to page 4, FIG. 1)

しかしながら、上記従来の断熱扉１１によると、隣接する粘着テープ２７間には折り返された密着部２４ｃの開放端と外装材２４ａとの隙間２４ｄが形成される。密着部２４ｃと外装材２４ａとの間の空気や、密着部２４ｃと外装材２４ａとの間に侵入した発泡断熱材２６によるガスは隙間２４ｄから矢印Ｄ（図１１参照）に示すように外装材２４ａ上に流出する。 However, according to the conventional heat insulating door 11, the gap 24d between the open end of the folded back contact portion 24c and the exterior material 24a is formed between the adjacent adhesive tapes 27 . As shown by the arrow D (see FIG. 11 ), the air between the contact portion 24c and the exterior material 24a and the gas generated by the foamed heat insulating material 26 that has entered between the contact portion 24c and the exterior material 24a are indicated by the arrow D (see FIG. 11 ). It flows out on 24a.

また、密着部２４ｃの側方の開口２４ｅからも密着部２４ｃと外装材２４ａとの間の空気やガスが流出する。このため、密着部２４ｃと内板成型品２２との間には空間部２８が以前として形成される。その結果、発泡断熱材２６の発泡時の熱によって、内板成型品２２が軟化するとともに空間部２８の空気やガスが膨張し、内板成型品２２の変形が生じる問題があった。   Further, air and gas between the contact portion 24c and the exterior material 24a also flow out from the side opening 24e of the contact portion 24c. For this reason, the space part 28 is formed as before between the close contact part 24 c and the inner plate molded product 22. As a result, there is a problem in that the inner plate molded product 22 is softened and the air or gas in the space 28 expands due to heat generated when the foam heat insulating material 26 is foamed, and the inner plate molded product 22 is deformed.

本発明は、真空断熱材を有して変形を容易に防止できる断熱扉及びそれを用いた貯蔵庫を提供することを目的とする。   An object of this invention is to provide the heat insulation door which has a vacuum heat insulating material and can prevent a deformation | transformation easily, and a storage using the same.

上記目的を達成するために本発明は、貯蔵庫の前面を開閉する断熱扉において、前記貯蔵庫の内面に面して配されるとともに樹脂成形品から成る内板成型品と、前記貯蔵庫の外面に面して配されるとともに前記内板成型品に対峙する外板成型品と、前記内板成型品の裏面に固着される真空断熱材と、前記内板成型品と前記外板成型品との間に充填される発泡断熱材とを備え、前記真空断熱材は芯材を内包する外装材の端部を密着した密着部により密閉して成り、前記密着部を前記内板成型品側に折り返して前記内板成型品に面した前記密着部の開放端を、側方を開放して前記開放端の長手方向の両側端に亙って粘着テープにより前記外装材に貼着するとともに、前記密着部の側方近傍の前記内板成型品に排気孔を設けたことを特徴としている。 In order to achieve the above object, the present invention provides a heat insulating door that opens and closes a front surface of a storage, and is arranged to face the inner surface of the storage, and is an inner plate molded product made of a resin molded product, and an outer surface of the storage. Between the inner plate molded product and the outer plate molded product, the outer plate molded product facing the inner plate molded product, the vacuum heat insulating material fixed to the back surface of the inner plate molded product, The vacuum heat insulating material is formed by sealing an end portion of the exterior material containing the core material with a close contact portion, and the close contact portion is folded back to the inner plate molded product side. The open end of the close contact portion facing the inner plate molded product is attached to the exterior material with an adhesive tape over both side ends in the longitudinal direction of the open end , and the close contact portion is characterized in the lateral said plate moldings near to the provision of the vent hole

この構成によると、発泡断熱材は内板成型品の裏面に固着される真空断熱材に接して内板成型品と外板成型品との間に充填される。真空断熱材の外装材の端部を密着した密着部は折り返されて粘着テープにより開放端が外装材に貼着される。密着部と外装材との間の空気や、密着部と外装材との間に侵入した発泡断熱材から発生するガスは、粘着テープ間に形成される密着部の開放端と外装材との隙間や、密着部の側方に形成される開口から外装材上に流出し、密着部近傍の排気孔から排気される。   According to this configuration, the foam heat insulating material is filled between the inner plate molded product and the outer plate molded product in contact with the vacuum heat insulating material fixed to the back surface of the inner plate molded product. The close contact portion where the end portion of the exterior material of the vacuum heat insulating material is in close contact is folded back and the open end is adhered to the exterior material by the adhesive tape. The air generated between the adhesive part and the exterior material, or the gas generated from the foam insulation that has entered between the adhesive part and the exterior material, is a gap between the open end of the adhesive part formed between the adhesive tape and the exterior material. Or, it flows out from the opening formed on the side of the close contact portion onto the exterior material and is exhausted from the exhaust hole near the close contact portion.

また、密着部の開放端と外装材との間が粘着テープにより塞がれる。 Further, the adhesive tape closes the space between the open end of the close contact portion and the exterior material.

また本発明の貯蔵庫は上記各構成の断熱扉を備えたことを特徴としている。   The storage according to the present invention is characterized by including the above-described heat insulating doors.

本発明によると、密着部の近傍の内板成型品に排気孔を設けたので、密着部と外装材との間の空気や発泡時のガスが排気孔から排気される。これにより、密着部と内板成型品との間の空間部の発生が防止されるため、内板成型品の裏面が発泡断熱材により支持される。従って、発泡断熱材の発泡時の熱による内板成型品の変形を防止することができる。   According to the present invention, since the exhaust hole is provided in the inner plate molded product in the vicinity of the close contact portion, the air between the close contact portion and the exterior material and the gas during foaming are exhausted from the exhaust hole. Thereby, since generation | occurrence | production of the space part between a contact | adherence part and an inner-plate molded product is prevented, the back surface of an inner-plate molded product is supported by a foam heat insulating material. Therefore, it is possible to prevent deformation of the inner plate molded product due to heat generated when the foam heat insulating material is foamed.

また本発明によると、密着部の開放端の長手方向の両側端に亙って粘着テープを貼着し、密着部の側方の内板成型品に排気孔を設けたので、密着部の開放端と外装材との隙間が塞がれ、密着部と外装材との間の空気や発泡時のガスが密着部の側方の開口のみから流出する。従って、密着部の側方の排気孔から容易に空気やガスを排気することができ、内板成型品の変形をより確実に防止することができる。   Further, according to the present invention, the adhesive tape is stuck over both longitudinal ends of the open end of the close contact portion, and the exhaust hole is provided in the inner plate molded product on the side of the close contact portion. The gap between the end and the exterior material is closed, and the air between the contact portion and the exterior material or the gas during foaming flows out only from the side opening of the contact portion. Therefore, air or gas can be easily exhausted from the exhaust hole on the side of the close contact portion, and deformation of the inner plate molded product can be prevented more reliably.

FIG. 5 is a cross-sectional view showing the heat insulating door 12. A vacuum heat insulating material 24 is fixed to the back surface of the inner plate molded product 22 by a double-sided adhesive tape 25, and a foam heat insulating material 26 is in contact with the vacuum heat insulating material 24 between the outer plate molded product 23 and the inner plate molded product 22. Filled. An exhaust hole 22 b for exhausting air or gas generated when foaming the foam heat insulating material 26 is provided at the tip of the protruding portion 22 a of the inner plate molded product 22.

図６は図５のＡ−Ａ断面図を示しており、図７は真空断熱材２４の平面図を示している。真空断熱材２４は袋状の外装材２４ａ内にガラス繊維等の芯材２４ｂを内包し、外装材２４ａは内部を真空に維持して端部を密着した密着部２４ｃにより密閉されている。密着部２４ｃは内板成型品２２側に折り返され、粘着テープ２７により開放端が長手方向の両側端に亙って外装材２４ａに貼着されている。   6 shows a cross-sectional view taken along the line AA of FIG. 5, and FIG. 7 shows a plan view of the vacuum heat insulating material 24. FIG. The vacuum heat insulating material 24 encloses a core material 24b such as glass fiber in a bag-shaped exterior material 24a, and the exterior material 24a is hermetically sealed by a close contact portion 24c that keeps the inside in a vacuum and closes the end portions. The close contact portion 24c is folded back to the inner plate molded product 22 side, and an open end thereof is adhered to the exterior member 24a over both side ends in the longitudinal direction by an adhesive tape 27.

また、密着部２４ｃの側方の内板成型品２２には、空気や発泡断熱材２６の発泡時に発生するガスを排気する排気孔２２ｃ（図５参照）が設けられる。   Further, the inner plate molded product 22 on the side of the close contact portion 24c is provided with an exhaust hole 22c (see FIG. 5) for exhausting air or a gas generated when the foam heat insulating material 26 is foamed.

図８は断熱扉１２の製造方法を示す斜視図である。外板成型品２３は下金型（不図示）に設置され、真空断熱材２４が固着された内板成型品２２が上金型（不図示）に設置される。外板成型品２３上にはウレタン注入設備（不図示）からウレタン混合液３０が注入され、上金型と下金型とが合わされる。そして、ウレタン混合液３０を加熱して発泡し、外板成型品２３と内板成型品２２との間に発泡ウレタンから成る発泡断熱材２６（図５参照）が充填される。従って、真空断熱材２４及び発泡断熱材２６により高い断熱効果を得ることができる。   FIG. 8 is a perspective view showing a method for manufacturing the heat insulating door 12. The outer plate molded product 23 is installed in a lower mold (not shown), and the inner plate molded product 22 to which the vacuum heat insulating material 24 is fixed is installed in an upper mold (not shown). A urethane mixed solution 30 is injected onto the outer plate molded product 23 from a urethane injection facility (not shown), and the upper mold and the lower mold are combined. Then, the urethane mixed liquid 30 is heated and foamed, and a foam heat insulating material 26 (see FIG. 5) made of foamed urethane is filled between the outer plate molded product 23 and the inner plate molded product 22. Therefore, a high heat insulating effect can be obtained by the vacuum heat insulating material 24 and the foam heat insulating material 26.

本実施形態によると、密着部２４ｃの側方の内板成型品２２に排気孔２２ｃを設けたので、密着部２４ｃと外装材２４ａとの間の空気や、密着部２４ｃと外装材２４ａとの間に侵入した発泡断熱材２６によるガスは、密着部２４ｃの側方の排気孔２２ｃから排気される。これにより、密着部２４ｃと内板成型品２２との間の空間部２８（図１０参照）の発生が防止されるため、内板成型品２２の裏面全体が発泡断熱材２６により支持される。従って、発泡断熱材２６の発泡時の熱による内板成型品２２の変形を防止することができる。   According to this embodiment, since the exhaust hole 22c is provided in the inner plate molded product 22 on the side of the close contact portion 24c, the air between the close contact portion 24c and the exterior material 24a, or between the close contact portion 24c and the exterior material 24a. The gas by the foam heat insulating material 26 that has entered between is exhausted from the exhaust holes 22c on the side of the close contact portion 24c. Thereby, since the generation of the space 28 (see FIG. 10) between the contact portion 24c and the inner plate molded product 22 is prevented, the entire back surface of the inner plate molded product 22 is supported by the foam heat insulating material 26. Therefore, it is possible to prevent the inner plate molded product 22 from being deformed by heat generated when the foam heat insulating material 26 is foamed.

尚、排気孔２２ｃを密着部２４ｃの近傍に設けてもよい。しかしながら、密着部２４ｃの開放端の長手方向の両側端に亙って粘着テープ２７を貼着して排気孔２２ｃを密着部２４ｃの側方に設けると、より確実に空間部２８（図１０参照）の発生を防止することができる。即ち、密着部２４ｃの開放端と外装材２４ａとの隙間が粘着テープ２７により塞がれ、密着部２４ｃと外装材２４ａとの間の空気や発泡時のガスが密着部２４ｃの側方の開口２４ｅのみから流出する。従って、密着部２４ｃの側方の排気孔２２ｃから容易に空気やガスを排気することができ、内板成型品２２の変形をより確実に防止することができる。   In addition, you may provide the exhaust hole 22c in the vicinity of the contact | adherence part 24c. However, if the adhesive tape 27 is attached to the both ends in the longitudinal direction of the open end of the close contact portion 24c and the exhaust hole 22c is provided on the side of the close contact portion 24c, the space portion 28 (see FIG. 10) is more reliably provided. ) Can be prevented. That is, the gap between the open end of the close contact portion 24c and the exterior material 24a is closed by the adhesive tape 27, and the air between the close contact portion 24c and the exterior material 24a and the gas during foaming are opened to the side of the close contact portion 24c. It flows out only from 24e. Therefore, air or gas can be easily exhausted from the exhaust hole 22c on the side of the close contact portion 24c, and deformation of the inner plate molded product 22 can be prevented more reliably.

本実施形態において、冷蔵庫１の断熱扉について説明しているが、冷凍庫や保温庫等の他の貯蔵庫を開閉する断熱扉であってもよい。   In this embodiment, although the heat insulation door of the refrigerator 1 is demonstrated, the heat insulation door which opens and closes other storages, such as a freezer and a heat retention box, may be sufficient.

本発明によると、冷蔵庫、冷凍庫、保温庫等の貯蔵庫に利用することができる。   According to this invention, it can utilize for storages, such as a refrigerator, a freezer, and a heat storage.
