冷凍室15の背面には冷気を生成する冷却室が設けられ、冷却室内には、冷却器、および、冷却器で冷却した冷気を冷蔵室12、切換室14、製氷室13、野菜室16、冷凍室15に送風する冷却ファンが配置される。さらに冷却ファンからの風量を調節する風量調節ダンパーが風路内に設置されている。また、冷却器やその周辺に付着する霜や氷を除霜するためにラジアントヒータ、ドレンパン、ドレンチューブ、蒸発皿等が構成されている。   A cooling chamber for generating cold air is provided on the back surface of the freezer compartment 15, and in the cooling chamber, the cooler, and the cold air cooled by the cooler 12, the switching chamber 14, the ice making chamber 13, the vegetable chamber 16, A cooling fan that blows air to the freezer compartment 15 is arranged. Further, an air volume adjusting damper for adjusting the air volume from the cooling fan is installed in the air path. Further, a radiant heater, a drain pan, a drain tube, an evaporating dish and the like are configured to defrost frost and ice adhering to the cooler and its surroundings.

冷蔵室12は冷蔵保存のために凍らない温度を下限に通常1℃〜5℃とし、最下部の野菜室16は冷蔵室12と同等もしくは若干高い温度設定の2℃〜7℃としている。また、冷凍室15は冷凍温度帯に設定されており、冷凍保存のために通常−22℃〜−15℃で
設定されているが、冷凍保存状態の向上のために、例えば−30℃や−25℃の低温で設定されることもある。
The refrigerator compartment 12 is normally set to 1 ° C. to 5 ° C. at the lower limit of the temperature at which it is not frozen for refrigerated storage. In addition, the freezer compartment 15 is set in a freezing temperature zone, and is usually set at −22 ° C. to −15 ° C. for frozen storage. For example, in order to improve the frozen storage state, −30 ° C. or − It may be set at a low temperature of 25 ° C.

製氷室13は冷蔵室12内の貯水タンクから送られた水で室内上部に設けられた自動製氷機で氷をつくり、室内下部に配置した貯氷容器に貯蔵する。   The ice making chamber 13 creates ice with water sent from a water storage tank in the refrigerator compartment 12 by an automatic ice maker provided at the upper part of the room and stores it in an ice storage container disposed at the lower part of the room.

切換室14は、1℃〜5℃で設定される冷蔵、2℃〜7℃で設定される野菜、通常−22℃〜−15℃で設定される冷凍の温度帯以外に、冷蔵温度帯から冷凍温度帯の間で予め設定された温度帯に切り換えることができる。切換室14は製氷室13に並設された独立扉を備えた収納室であり、引き出し式の扉を備えることが多い。   The switching chamber 14 is not only refrigerated set at 1 ° C to 5 ° C, vegetables set at 2 ° C to 7 ° C, but also frozen at a temperature set at -22 ° C to -15 ° C. It is possible to switch to a preset temperature range between the freezing temperature ranges. The switching chamber 14 is a storage chamber provided with an independent door arranged in parallel with the ice making chamber 13, and is often provided with a drawer-type door.

なお、本実施の形態1では、切換室14を、冷蔵と冷凍の温度帯までを含めた収納室としているが、冷蔵は冷蔵室12と野菜室16、冷凍は冷凍室15に委ねて、冷蔵と冷凍の中間の上記温度帯のみの切り換えに特化した収納室としても構わない。また、特定の温度帯、例えば近年冷凍食品の需要が多くなってきたことに伴い、冷凍に固定された収納室でも構わない。   In the first embodiment, the switching chamber 14 is a storage room including the temperature range of refrigeration and freezing. However, the refrigeration is performed by the refrigerator compartment 12 and the vegetable compartment 16, and the freezing is performed by the freezer compartment 15. It is also possible to use a storage room specialized for switching only the above temperature range between the refrigeration and the freezing. Moreover, the storage room fixed to freezing may be sufficient as the demand for frozen foods has increased in recent years, for example, frozen food.

野菜室16は、断熱壁を有する筐体11と冷気漏れを抑制するガスケット18、野菜室の引出扉16aにて構成されている。引出扉16aは、フレーム19に固定された傾斜機構30の扉回転軸33と棒上のアーム31によって開口方向へ所定角度回転可能に枢支される。引出扉16aと傾斜機構30のアーム連結部32の一部はウレタン内に埋没されており、連結強度を保っている。フレーム19は、野菜室16の内壁の側面と底面に接して固定された引出レール20上を前後方向自由にスライドする構成となっている。引出扉16aの庫内側には背面収納ケース37が取り付けられ、フレーム19には収納ケース22が取付けられている。これによって、引出扉16aは、所定角度回転する傾斜動作とスライド動作が可能になり、それに伴って、背面収納ケース37と、収納ケース22が動作する。また、閉扉時は密閉保持機構21によって、開扉を妨げない範囲で密閉を維持している。   The vegetable compartment 16 includes a casing 11 having a heat insulating wall, a gasket 18 that suppresses cold air leakage, and a drawer door 16a of the vegetable compartment. The drawer door 16a is pivotally supported by a door rotation shaft 33 of the tilt mechanism 30 fixed to the frame 19 and an arm 31 on the bar so as to be rotatable by a predetermined angle in the opening direction. A part of the drawer door 16a and the arm connecting portion 32 of the tilting mechanism 30 is buried in urethane to maintain the connection strength. The frame 19 is configured to freely slide in the front-rear direction on a drawer rail 20 fixed in contact with the side and bottom surfaces of the inner wall of the vegetable compartment 16. A back storage case 37 is attached to the inside of the drawer door 16 a and a storage case 22 is attached to the frame 19. As a result, the drawer door 16a can be tilted and slid at a predetermined angle, and the rear storage case 37 and the storage case 22 operate accordingly. Further, when the door is closed, the hermetic holding mechanism 21 maintains the hermetic seal in a range that does not hinder the opening of the door.

傾斜機構30は、扉回転軸33とアーム31に加え、傾斜動作に連動して開口側と反対方向に移動し引出扉16aを開扉方向へ押し出す、押し出し部35によって構成される。押し出し部35は、筐体11の内箱に設けられた留め部36を押し出すことで、傾斜角度に応じて引出扉16aを開扉方向へ押し出す。留め形状は、引出レール20の一部に留め部材として固定してもよい。また、押し出し部35は、留め部36に接触にし、引出扉16aを開口側と反対方向に押し出すことができれば、並進運動でなくても良い。傾斜角度と押し出し部35の移動量を、調節することでガスケットに圧縮負荷を与えずに、傾斜動作を行いつつ引出扉16aを開扉方向へ移動させることができる。   In addition to the door rotation shaft 33 and the arm 31, the tilt mechanism 30 is configured by an extruding portion 35 that moves in the direction opposite to the opening side in conjunction with the tilting operation and pushes the drawer door 16a in the door opening direction. The push-out part 35 pushes out the pull-out door 16a in the opening direction according to the inclination angle by pushing out the fastening part 36 provided in the inner box of the housing 11. The fastening shape may be fixed to a part of the drawer rail 20 as a fastening member. Further, the push-out portion 35 may not be in translational motion as long as the push-out portion 35 can be brought into contact with the fastening portion 36 and can push out the drawer door 16a in the direction opposite to the opening side. By adjusting the inclination angle and the amount of movement of the pushing portion 35, the drawer door 16a can be moved in the opening direction while performing an inclination operation without applying a compression load to the gasket.

押し出し部35が連動して動作する仕組みについては、図3のように取り付けプレート40の回転軸41にアーム31が枢支される。引出扉16aとアーム31の連結部は、上下に移動可能なスライダー43と回転自由のピン42によって構成される。押し出し部35は、アーム31の引出扉16aと反対側の先端に設けられる。この場合、引出扉16aの連結部のピン42と回転軸41間の距離L1と、回転軸41と押し出し部35間の距離L2の比によって、回転角度と押し出し量の関係が決まる。   Regarding the mechanism in which the push-out portion 35 operates in conjunction with each other, the arm 31 is pivotally supported on the rotating shaft 41 of the mounting plate 40 as shown in FIG. The connecting portion between the drawer door 16a and the arm 31 is constituted by a slider 43 that can move up and down and a pin 42 that can rotate freely. The pushing portion 35 is provided at the tip of the arm 31 on the side opposite to the drawer door 16a. In this case, the relationship between the rotation angle and the push-out amount is determined by the ratio of the distance L1 between the pin 42 of the connecting portion of the drawer door 16a and the rotary shaft 41 and the distance L2 between the rotary shaft 41 and the push-out portion 35.

傾斜機構30が引出扉16aを回動傾斜させる回転軸の中心は、引出レール20を構成する部材の最下部より上方に位置している。   The center of the rotation shaft by which the tilt mechanism 30 pivots and tilts the drawer door 16 a is located above the lowermost part of the members constituting the drawer rail 20.

以上のように構成された冷蔵庫について、以下、その動作を順に説明する。   About the refrigerator comprised as mentioned above, the operation | movement is demonstrated in order below.

使用者が野菜室の引出扉16aの把持部16bを把持し、引き出し方向に開扉力を加える。引出扉16aは、扉回転軸33を中心に開口方向へ回転し傾斜動作を開始する。これにより、磁着したガスケット18は上辺から離間する。ガスケット18が上辺から離間することで、全辺を同時に離間させるより小さな力で開扉する事ができる。   The user grips the grip 16b of the drawer door 16a of the vegetable compartment and applies a door opening force in the pull-out direction. The drawer door 16a rotates in the opening direction around the door rotation shaft 33 and starts tilting. Thereby, the magnetized gasket 18 is separated from the upper side. By separating the gasket 18 from the upper side, the door can be opened with a smaller force than separating all the sides at the same time.

図4において、A1は留め部36の端部位置を、B1は扉回転軸33の中心位置を示す。A2、B2はそれぞれ押し出し部35が距離X1移動した位置を示す。引出扉16aの回動動作と同時に、引出扉16aの傾斜動作と連動して、押し出し部35が位置A1に固定された留め部36を押し出し、引出扉16aが開扉方向へ押し出される(開扉運動)。図4bは、押し出し部35が距離X1を移動したときである。押し出し部35が移動したことで、位置B1で閉扉していた引出扉16aは、位置B2まで開扉運動を行う。このとき、位置A1とA2間の距離と、位置B1とB2間の距離は同一である。   In FIG. 4, A <b> 1 indicates the end position of the fastening portion 36, and B <b> 1 indicates the center position of the door rotation shaft 33. A2 and B2 respectively indicate positions where the pushing portion 35 has moved by the distance X1. Simultaneously with the pivoting operation of the drawer door 16a, in conjunction with the tilting operation of the drawer door 16a, the push-out portion 35 pushes out the fastening portion 36 fixed at the position A1, and the drawer door 16a is pushed out in the door opening direction (open door). motion). FIG. 4B shows a case where the pushing portion 35 has moved the distance X1. As the push-out portion 35 moves, the drawer door 16a that has been closed at the position B1 performs a door-opening movement to the position B2. At this time, the distance between the positions A1 and A2 and the distance between the positions B1 and B2 are the same.

以上のように、引出扉16aの引出し動作と連動して引出扉16aの上部を前方へ回動させる引出ユニットの動作過程における引出扉16aの下端、あるいはガスケットの端部60は、冷蔵庫の構成部材と干渉せずに前方に移動することができ、冷蔵庫の使い勝手を高めることができるとともに、ガスケットの信頼性を高めることができる。   As described above, the lower end of the drawer door 16a or the gasket end 60 in the operation process of the drawer unit that rotates the upper portion of the drawer door 16a forward in conjunction with the drawer operation of the drawer door 16a is a component of the refrigerator. It is possible to move forward without interfering with the above, and it is possible to improve the convenience of the refrigerator and improve the reliability of the gasket.

すなわち、ガスケット18の最も筐体11に接近するガスケットの端部60が、開扉直前の位置より筐体側に移動することは幾何学的にはない。ただし、部品間のスキや公差により、ガスケット18の厚みの30%までは、筐体側へ移動する設計にしても良い。これにより、ガスケット18の変形量は30%以下となる。引出扉16aは所定角度まで、傾斜動作とそれと連動した開扉運動を行う。所定角度に到達すると、傾斜と押し出し部35の移動は終了する。この時、背面収納ケース37は所定角度傾いた状態となり、使用者は背面収納ケース37内の収納物、例えば2Lペットボトルなどを視認しやすく、取り出しやすい。ここで、所定角度は、例えば20度が野菜室のペットボトルを取り出しやすい。さらに引出扉16aを引き出し、収納ケース22の収納物を出し入れしたい場合は、所定角度傾いた状態のまま把持部16bを引き出すことで、引出扉16aを全開にする事ができる。閉扉時は、以上の動作を逆に行うことで閉扉が可能である。   That is, it is not geometrically that the gasket end portion 60 closest to the casing 11 of the gasket 18 moves to the casing side from the position immediately before opening the door. However, it may be designed to move to the housing side up to 30% of the thickness of the gasket 18 due to gaps and tolerances between parts. Thereby, the deformation amount of the gasket 18 becomes 30% or less. The drawer door 16a performs a tilting operation and a door opening movement in conjunction with the tilting operation up to a predetermined angle. When the predetermined angle is reached, the inclination and the movement of the pushing portion 35 are finished. At this time, the back storage case 37 is inclined at a predetermined angle, and the user can easily see and take out the stored items in the back storage case 37, such as 2L plastic bottles. Here, the predetermined angle is, for example, 20 degrees, and it is easy to take out the plastic bottle in the vegetable room. Further, when it is desired to pull out the drawer door 16a and put in and out the stored item in the storage case 22, the drawer door 16a can be fully opened by pulling out the gripping portion 16b while being inclined at a predetermined angle. When the door is closed, the door can be closed by performing the above operations in reverse.

図5(a)は本発明の引出扉の開扉前の状態を示す図である。図5(b)は、本発明の引出扉の開扉中で、押し出し部35が距離X2を移動したときを示す図である。なお、実施の形態1と同一構成は同一符号を付して詳細な説明は省略する。
(Embodiment 2)
Fig.5 (a) is a figure which shows the state before opening of the drawer door of this invention. FIG. 5 (b) is a diagram showing a state in which the pushing portion 35 has moved a distance X2 while the drawer door of the present invention is being opened. The same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図5において、アーム56の引出扉16a側を回転自由なピン50と先端アーム51を介して引出扉16aに固定し、引出扉16aと逆側にラックオピニオン52を取り付ける。逆側にラックオピニオン52とかみ合う場所に平歯車53を設け、平歯車53とかみ合う場所に押し出し部側のアーム55とラックオピニオン54を設ける。これにより、アーム56が引出扉16aの回動に伴い開口方向へ移動する力を反転させ、押し出し部35は、傾斜に伴い開口側と反対方向へ移動する。   In FIG. 5, the drawer door 16a side of the arm 56 is fixed to the drawer door 16a via a rotatable pin 50 and a tip arm 51, and a rack opinion 52 is attached to the opposite side of the drawer door 16a. On the opposite side, a spur gear 53 is provided at a position where it engages with the rack opinion 52, and an arm 55 and a rack opinion 54 on the pushing portion side are provided at a position where it engages with the spur gear 53. Thereby, the force which the arm 56 moves to an opening direction with rotation of the drawer | drawing-out door 16a is reversed, and the extrusion part 35 moves to the opposite direction to an opening side with inclination.

また、図5において、C1は留め部36の端部位置を、D1は扉回転軸33の中心位置を示す。C2、D2はそれぞれ押し出し部35が距離X2移動した位置を示す。押し出し部35が移動したことで、位置D1で閉扉していた引出扉16aは、位置D2まで開扉運動を行う。このとき、位置C1とC2間の距離と、位置D1とD2間の距離は同一である。この場合、軸取付け部34とアーム連結部32の取付け位置と二つのラックオピニオン52,54と平歯車53のギア比によって、引出扉16aの回転角度と、押し出し部の押し出し量X2が決まる。   In FIG. 5, C <b> 1 indicates the end position of the fastening portion 36, and D <b> 1 indicates the center position of the door rotation shaft 33. C2 and D2 respectively indicate positions where the pushing portion 35 has moved by a distance X2. As the push-out portion 35 moves, the drawer door 16a that has been closed at the position D1 performs a door-opening movement to the position D2. At this time, the distance between the positions C1 and C2 is the same as the distance between the positions D1 and D2. In this case, the rotation angle of the drawer door 16a and the push-out amount X2 of the push-out portion are determined by the mounting positions of the shaft attachment portion 34 and the arm connecting portion 32 and the gear ratio between the two rack opinions 52 and 54 and the spur gear 53.

冷凍室15についても、同様の機構であるため省略する。本実施例では、野菜室16、冷凍室15の両方に本機構を備えたが、どちらか一方でも良い。さらに、製氷室13や切換室14に備えても良い。   The freezer compartment 15 is also omitted because it has the same mechanism. In the present embodiment, both of the vegetable compartment 16 and the freezer compartment 15 are provided with this mechanism, but either one may be used. Further, the ice making chamber 13 and the switching chamber 14 may be provided.
