[0010] 以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実 施の形態によって、本発明が限定されるものではない。  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited by the embodiment.
[0011] (実施の形態 1)  (Embodiment 1)
図 1は本実施の形態 1の冷蔵庫の断面図である。図示のように、冷蔵庫の内部は複 数の貯蔵室に仕切られる。貯蔵室 25、 27及び 28は、引出し式扉 50を有する。例とし て、貯蔵室 27の引出し式扉の構成を以下に説明する。  FIG. 1 is a cross-sectional view of the refrigerator according to the first embodiment. As shown, the interior of the refrigerator is divided into a plurality of storage rooms. The storage rooms 25, 27 and 28 have a drawer door 50. As an example, the configuration of the drawer door of the storage room 27 will be described below.
[0012] 図 2は、図 1における矢視 2— 2断面図であり、図 3は、レール部材 32の分解図であ る。図 1に示す貯蔵室 27の引出し式扉 50は、前後方向に移動できるように貯蔵室の 両側端でリニア形のレール部材 32に支持される。 FIG. 2 is a sectional view taken along line 2-2 in FIG. 1, and FIG. 3 is an exploded view of the rail member 32. The pull-out door 50 of the storage room 27 shown in FIG. 1 is supported by linear rail members 32 at both ends of the storage room so as to be movable in the front-rear direction.
[0013] レール部材 32は、固定レール 32aと、移動レール 32bと、固定レール 32aと移動レ ール 32bとの間に置かれた中間レール 32cと、中間レール 32cと、固定レール 32a及 び移動レール 32bとの係合を支持する転動体である複数の球 32dとを一体ィ匕して、 固定レール 32aと移動レール 32bの間は小さなクリアランスで構成される。球 32dに 代えて、例えばローラを転動体として用いてもよい。固定レール 32aは、貯蔵室の側 壁に設けた側壁補強板 31に固定される。 [0013] The rail member 32 includes a fixed rail 32a, a moving rail 32b, an intermediate rail 32c placed between the fixed rail 32a and the moving rail 32b, an intermediate rail 32c, a fixed rail 32a, and a moving rail. A plurality of balls 32d, which are rolling elements supporting the engagement with the rail 32b, are integrally formed, and a small clearance is formed between the fixed rail 32a and the moving rail 32b. Instead of the ball 32d, for example, a roller may be used as a rolling element. The fixed rail 32a is fixed to the side wall reinforcing plate 31 provided on the side wall of the storage room.
[0014] 図 4は引出し式扉の分解図、図 5は引出し式扉の背面図である。図示のように、引 出し式扉 50は、前面扉 29と、前面扉 29の背面に取り付けられた一対の扉フレーム 3FIG. 4 is an exploded view of the drawer-type door, and FIG. 5 is a rear view of the drawer-type door. As shown, the pull-out door 50 includes a front door 29 and a pair of door frames 3 attached to the rear of the front door 29.
4とを有する。 [0015] 扉フレーム 34は、下端にステップ状の折り曲げ部 34aを有する。扉フレーム 34と移 動レール 32bとの結合の一例が図 4に示される。すなわち、扉フレーム 34は、折り曲 げ部 34aでレール部材 32の移動レール 32bを覆って、扉フレーム 34の穴 34eを通し てねじ 34dにより、移動レール 32bの上に取り付けられる。図 2に示されるように、被冷 却物を収納する容器 33が、一対の扉フレーム 34の間に支持される。 And 4. [0015] The door frame 34 has a step-shaped bent portion 34a at the lower end. An example of the connection between the door frame 34 and the moving rail 32b is shown in FIG. That is, the door frame 34 covers the moving rail 32b of the rail member 32 with the bent portion 34a, and is mounted on the moving rail 32b by the screw 34d through the hole 34e of the door frame 34. As shown in FIG. 2, a container 33 for storing an object to be cooled is supported between a pair of door frames.
[0016] 図 6に示すように、前面扉 29は、扉フレーム 34を取り付けるための補強板 38と断熱 材 37を内部に有する。補強板 38は、扉の背面板 35より高剛性の材料で形成される 。図 7に示すように、扉フレーム 34の折り曲げ部 34aは、下部の寸法 Fより上部の寸 法 Eを狭くした下方に開口する台形形状に形成される。これにより扉フレーム 34の移 動レール 32bへの取り付けが容易となる。図 8に示すように、一対の扉フレーム 34は コの字形に一体形成しても良い。  As shown in FIG. 6, the front door 29 has a reinforcing plate 38 for mounting the door frame 34 and a heat insulating material 37 inside. The reinforcing plate 38 is formed of a material having higher rigidity than the rear plate 35 of the door. As shown in FIG. 7, the bent portion 34a of the door frame 34 is formed in a trapezoidal shape that opens downward, in which the upper dimension E is narrower than the lower dimension F. This facilitates attachment of the door frame 34 to the moving rail 32b. As shown in FIG. 8, the pair of door frames 34 may be integrally formed in a U-shape.
[0017] 扉フレーム 34は、線膨張率 1. 0 X 10_6 (K_1)以上、 3. O X 10_6 (Κ_ 1)以下を有 する材料で構成され、低温時に扉支持部材が収縮することによる影響を低減する。ま た、扉フレーム 34は、熱伝導率が 0. lWZ (m.K)以上、 0. 2WZ (m'K)以下の材 料で構成され、複数の貯蔵室の温度帯が異なる場合に扉支持部材からの熱伝達を 抑制する。 [0017] The door frame 34 is made of a material having a linear expansion coefficient of not less than 1.0 X 10 -6 (K _1 ) and not more than 3. OX 10 _6 (Κ _ 1 ). The effects of The door frame 34 is made of a material having a thermal conductivity of 0.1 WZ (mK) or more and 0.2 WZ (m'K) or less. Suppress heat transfer from
[0018] 前面扉 29を引出すと、レール部材 32の移動レール 32bと中間レール 32c力球 32d の回転により滑らかに前方に移動する。それに伴い、扉フレーム 34に支持された容 器 33も引出され、容器内の被冷却物を取出し又は収納できる。固定レール 32aと移 動レール 32bの間のクリアランスは小さいので、扉は揺れずに引き出すことができ、か つ、扉の傾きなどの外観不良も防止できる。これらの効果はレール部材 32の引出し 代が大き 、ほど効果的である。  When the front door 29 is pulled out, the front rail 29 smoothly moves forward by the rotation of the moving rail 32b of the rail member 32 and the intermediate rail 32c. Along with this, the container 33 supported by the door frame 34 is also pulled out, and the object to be cooled in the container can be taken out or stored. Since the clearance between the fixed rail 32a and the moving rail 32b is small, the door can be pulled out without swinging, and appearance defects such as the inclination of the door can be prevented. These effects are more effective as the allowance for pulling out the rail member 32 is larger.
