Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は冷蔵庫の扉に係り、特に意匠効果向上、耐食
性向上、安全性の向上等に関するものである。Description: TECHNICAL FIELD The present invention relates to a refrigerator door, and more particularly to an improvement in a design effect, an improvement in corrosion resistance, an improvement in safety, and the like.
従来技術は第２図のＡ−Ａ断面図である第３図に示す
如く鉄板等で製作した扉外板１の上端及び下端に合成樹
脂等で製作した枠部材２を該枠部材２と一体成形したリ
ブ2aと枠部材２の前面部2bとの隙部2cに扉外板１を嵌入
する如く挿着し、しかる後断熱材３を充填させたもので
ある。In the prior art, a frame member 2 made of synthetic resin or the like is integrated with the frame member 2 at the upper end and lower end of a door outer plate 1 made of an iron plate or the like as shown in FIG. The door outer plate 1 is inserted into the gap 2c between the molded rib 2a and the front surface 2b of the frame member 2 so as to fit, and then the heat insulating material 3 is filled.
上記従来技術は枠部材２の前面部2bが扉外板１の外表
面部1aよりでているため扉外板１の外表面部1aに冷蔵庫
内温度と外気温の温度差により高湿度状況下等により付
着する露などが滴下した場合枠部材２の前面部2bとリブ
2aより形成する隙部2cに溜まり断熱材３側へ侵入しやす
く該侵入水により扉外板１の端面部より錆が発生する点
について配慮されておらず、耐食性についての問題があ
った。In the above prior art, the front surface 2b of the frame member 2 is located outside the outer surface 1a of the door outer panel 1, so that the outer surface 1a of the door outer panel 1 is exposed to high humidity conditions due to the temperature difference between the refrigerator temperature and the outside air temperature. When the dew or the like which adheres to the frame member 2 drops, the front part 2b of the frame member 2 and the rib
No consideration is given to the fact that the water accumulates in the gap 2c formed by the hole 2a and easily penetrates into the heat insulating material 3 side, and rust is generated from the end face of the door outer panel 1 due to the infiltration water, and there is a problem in corrosion resistance.
本発明は、上記水の侵入を防止する冷蔵庫の扉を提供
することにある。An object of the present invention is to provide a refrigerator door that prevents the above water from entering.
上記目的は扉外板表面と枠部材の前面部を同一面もし
くは、扉外板表面よりも枠部材の前面部をへこますこと
により達成される。The above object is achieved by making the front surface of the frame member concave with respect to the front surface of the door member with the same surface or the front surface of the frame member.
扉外板の上端及び下端部を略クランク状の深さを有す

でっぱりがなくなり若しくは小さくなる。これによって
扉外表面に温度差により付着した露が滴下した場合枠部
材の断熱材側への侵入が非常に少なくなり扉外板の耐食
効果の大巾な向上を図れるものである。When the upper and lower ends of the door outer panel are engaged with the squeezed portion having a substantially crank-shaped depth, the outer surface of the door outer panel becomes flatter or smaller. Thus, when dew attached to the outer surface of the door due to the temperature difference drops, the penetration of the frame member into the heat insulating material side is extremely reduced, and the corrosion resistance of the outer panel of the door can be greatly improved.
以下本発明の一実施例を第２図のＡ−Ａ断面図である
第１図により説明する。An embodiment of the present invention will be described below with reference to FIG. 1 which is a cross-sectional view taken along line AA of FIG.

≧T3となるような傾斜部5dを設けるものである。The upper end 4a and the lower end 4b of the door outer plate 4 made of an iron plate or the like are provided with substantially crank-shaped throttles 4a 'and 4b', respectively.
4b '4a diaphragm and the wall thickness T 1 of the front portion 5a of the frame member 5 made of a synthetic resin or the like be disposed portion', substantially crank shape so that the depth T 2 of the 4b 'becomes T 1 ≧ T 2 Apertures 4a ', 4b' are provided, and frame members 5
Front portion 5a and T 2 -T 1 = 0~1.0mm so that 0～1.0Mm step than the outer plate surface of the door outer plate 4, the restrictor 4a ', 4b' front portion of the frame member 5 to the portion Groove 5c composed of 5a and rib 5b
Then, the door body constituted by the door outer plate 4 and the frame member 5 is filled with the heat insulating material 6 to form a refrigerator door.
Further, in the door configured as described above, in order to minimize the gap 7 generated when the door outer plate 4 and the frame member 5 are combined, the door is provided at the front portion 5a of the frame member 5 at a position facing the door outer plate 4 and at the end surface. R for the R of the substantially crank-shaped throttles 4a ', 4b' of the outer plate 4
It is intended to provide a ≧ T 3 become such inclined portion 5d.

上を図れるものである。The upper end and the lower end of the door outer plate 4 are substantially crank-shaped throttles, and the depth at which the frame member 5 disposed in the throttle portion has a step (dent) of 0 to 1.0 mm from the surface of the door outer plate 4. The door of the refrigerator, which is formed by inserting the frame member 5 having a thin front portion having a thickness of 0 to 1.0 mm from the depth of the aperture as described above and filling the heat insulating material 6 with the aperture portion having the The flatness of the door 4 can be reduced, and the design effect can be remarkably improved. The surface of the door outer plate 4 has a frame member 4 even if a human hand touches the food or the like when putting the food into or out of the refrigerator. Is not protruded from the surface of the door outer plate 4, so that the frame member 4 is not injured by being caught on the hand, and safety is considered. Furthermore, since there is no sticking, it is difficult for external force to be applied to the frame member 5, and it is possible to prevent the frame member 5 from peeling off from the heat insulating material 6. Further, when dew attached to the outer surface of the door due to a temperature difference drops, penetration of the frame member 5 into the heat insulating material 6 side is extremely reduced, so that the corrosion resistance of the door outer panel 4 can be greatly improved. .

率を更に低くすることができる。Further, in this embodiment, the end surface of the door outer plate is narrowed in a substantially crank shape, and the depth of the throttle is equal to or slightly greater than the thickness of the front portion of the frame member. In order to minimize the gap generated at the abutting portion with the squeezing portion, the portion facing the squeezed portion of the door skin at the end of the front face of the frame member is inclined more than the squeezing R of the door skin to escape the squeezed R. Thereby, the gap can be further reduced, and the probability of water intrusion can be further reduced.
本発明によれば扉表面よりでっぱりを皆無若しくは少
なくすることができることにより露等の侵入が非常に少
く耐食性を大巾に改良できるものである。ADVANTAGE OF THE INVENTION According to this invention, the penetration | invasion of a dew etc. can be very little, and corrosion resistance can be improved greatly because the protrusion can be made to be zero or less than a door surface.
