Description
本開示は、収納室の扉を自動で閉じる機能を備えた冷蔵庫に関する。
This disclosure relates to a refrigerator having a function of automatically closing a door of a storage room.
近年では、食生活の変化および郊外型の大型スーパーマーケットの増加から、日々買い物をする習慣が薄れて来ている。例えば、1週間分の食料品を纏め買いして冷蔵庫に保存しておくような傾向が強くなっている。また、比較的大型の冷蔵庫を使用する高齢者が増加しており、そのような使用者にとって纏め買いした食品と扉との総重量が重く、収納室の開閉が負担に感じられるようになってきている。
In recent years, the habit of daily shopping has faded due to changes in eating habits and the increase in suburban large supermarkets. For example, there is a strong tendency to buy food items for a week and store them in a refrigerator. In addition, the number of elderly people who use relatively large refrigerators is increasing, and for such users, the total weight of food and doors bought together is heavy, and opening and closing of the storage room can be felt as a burden. ing.
また、使用者が軽い力でドアを閉じようとすると、摩擦によってドアが途中で停止し、冷蔵庫の閉じ忘れが意図せず発生する頻度が増加している。扉が少しでも開いた状態で放置されると、暖気の侵入による保存性能の低下、冷却量の増加による消費電力の増大、並びに、外湿気の侵入による収納室内の結露および着霜が発生し、冷蔵庫の機能を損ねることになる。
Also, when the user tries to close the door with a light force, the door stops halfway due to friction, and the frequency of unintentional occurrence of forgetting to close the refrigerator is increasing. If the door is left open as much as possible, the storage performance will decrease due to the intrusion of warm air, the power consumption will increase due to the increased amount of cooling, and condensation and frost will form in the storage room due to the ingress of outside moisture. The function of the refrigerator will be impaired.
このような課題のうち、収納室の閉じ忘れ頻度を軽減する冷蔵庫として、自動閉扉機構を備え、半ドア状態を防止し、且つ扉を勢いよく閉じた際の衝撃を低減するものがある(特許文献1参照)。
Among such problems, as a refrigerator that reduces the frequency of forgetting to close the storage room, there is a refrigerator that includes an automatic door closing mechanism, prevents a half-door state, and reduces the impact when closing the door vigorously (patent) Reference 1).
図9は、特許文献1に記載された従来の冷蔵庫の引出し冷凍室周辺を側方から見た模式図である。
FIG. 9 is a schematic view of the periphery of the drawer freezer compartment of the conventional refrigerator described in Patent Document 1, as viewed from the side.
図9に示すように、従来の冷蔵庫は、本体筐体101と、本体筐体101内に設けられた貯蔵室と、貯蔵室の前面開口部を覆う引出し扉102と、引出し扉102とともに引き出され、食品が収納される収納容器103とを備える。また、従来の冷蔵庫は、引出し部と、引出し部に設けられた引き込みピン105と、引き込みピン105と当接または離反可能な扉閉鎖部106とを備える。引出し部は、引出し扉102と、収納容器103と、収納容器103を支持する枠体104とからなる。従来の冷蔵庫は、引出し部が本体筐体101から引き出され、あるいは本体筐体101に押し込まれると、引き込み部材である扉閉鎖部106が、引き込みピン105を引き込んで引出し扉102を閉じるよう構成されている。
As shown in FIG. 9, the conventional refrigerator is pulled out together with a main body casing 101, a storage chamber provided in the main body casing 101, a drawer door 102 covering the front opening of the storage chamber, and the drawer door 102. And a storage container 103 for storing food. The conventional refrigerator includes a drawer, a pull-in pin 105 provided in the drawer, and a door closing portion 106 that can come into contact with or separate from the pull-in pin 105. The drawer portion includes a drawer door 102, a storage container 103, and a frame body 104 that supports the storage container 103. The conventional refrigerator is configured such that when the drawer portion is pulled out from the main body casing 101 or pushed into the main body casing 101, the door closing portion 106 as a pulling member pulls the pull-in pin 105 and closes the drawer door 102. ing.
扉閉鎖部106は、内部に、粘性オイル等を利用して閉扉速度を減速させる手段、すなわち、摩擦負荷トルクまたは粘性負荷トルクを発生することで、扉が勢いよく閉じられた際の衝撃を低減する手段を備える。
The door closing unit 106 generates a friction load torque or a viscous load torque to reduce the closing speed by using viscous oil or the like inside, thereby reducing an impact when the door is closed vigorously. Means are provided.
しかしながら、上述したような従来の冷蔵庫の構成は、自閉機能を備えてはいるが、閉扉速度を減速しながら閉じるため、密閉直前に閉扉速度がほぼゼロとなり、ドアに隙間がある状態で停止してしまうことがある。特に、収納物の重量が重い時に、このような問題が頻繁に発生する。
However, although the conventional refrigerator configuration as described above has a self-closing function, it closes while decelerating the closing speed, so the closing speed becomes almost zero just before sealing and the door stops with a gap. May end up. In particular, such a problem frequently occurs when the weight of stored items is heavy.
また、減速手段を廃止した場合は、扉が勢いよく閉じられた際の衝撃を低減することができず、衝撃低減と確実な密閉とを両立させることが困難である。
Also, when the speed reduction means is abolished, it is difficult to reduce the impact when the door is closed vigorously, and it is difficult to achieve both impact reduction and reliable sealing.

A cooling chamber for generating cool air is provided on the back of the freezing chamber 15. A cooler and a cooling fan are disposed in the cooling chamber. The cooling fan blows the cold air cooled by the cooler to the refrigerator compartment 12, the switching room 14, the ice making room 13, the vegetable room 16, and the freezer room 15 through the air path. The air path is provided on the back of the refrigerator compartment 12, the switching compartment 14, the ice making compartment 13, the vegetable compartment 16, and the freezer compartment 15. Further, an air volume adjusting damper for adjusting the air volume from the cooling fan is installed in the air path. The cooling chamber is provided with a radiant heater, a drain pan, a drain tube evaporating dish, and the like in order to defrost the cooler and frost and ice adhering to the cooler.
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℃に設定される。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の2℃~7℃に設定される。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℃で設定される。なお、冷凍室15は、冷凍保存状態の向上のために、例えば-30℃または-25℃の低温で設定されることもある。

The switching chamber 14 is a refrigeration temperature zone set at 1 ° C. to 5 ° C., a vegetable temperature zone set at 2 ° C. to 7 ° C., a freezing temperature zone normally set at −22 ° C. to −15 ° C., And it is comprised so that it can switch to the temperature range preset between the refrigerator temperature zone and the freezing temperature zone. The switching chamber 14 is a storage chamber provided in parallel with the ice making chamber 13 and having an independent door. The switching chamber 14 often includes a drawer-type door.
なお、本実施の形態では、切換室14は、冷蔵温度帯から冷凍温度帯までの温度帯に切換可能な収納室として構成されている。しかし、冷蔵は、冷蔵室12および野菜室16に委ね、冷凍は、冷凍室15に委ねて、切換室14は、冷蔵温度帯と冷凍温度帯との間の温度帯でのみの切り換えに特化した収納室として構成されていてもよい。また、切換室14は、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、冷凍温度帯に固定された収納室として構成されていてもよい。
In the present embodiment, the switching chamber 14 is configured as a storage chamber that can be switched to a temperature zone from a refrigeration temperature zone to a freezing temperature zone. However, refrigeration is left to the refrigerator compartment 12 and the vegetable compartment 16, freezing is left to the freezer compartment 15, and the switching room 14 is specialized for switching only in the temperature zone between the refrigeration temperature zone and the freezing temperature zone. It may be configured as a storage room. In addition, the switching chamber 14 may be configured as a storage room fixed in a specific temperature range, for example, a frozen temperature range in accordance with the recent increase in demand for frozen food.
図2等に示すように、野菜室扉16aには、フレーム19によって支持された収納ケース20が取付けられている。引出しレール21は、野菜室16の内壁に固定されている。フレーム19は、引出しレール21上をスライドする構成となっている。また、フレーム19と野菜室扉16aとは、互いに組み合わされた構造となっている。このような構成により、フレーム19と収納ケース20とは、野菜室扉16aの開閉に伴って動作する。
As shown in FIG. 2 and the like, a storage case 20 supported by a frame 19 is attached to the vegetable compartment door 16a. The drawer rail 21 is fixed to the inner wall of the vegetable compartment 16. The frame 19 is configured to slide on the drawer rail 21. Moreover, the frame 19 and the vegetable compartment door 16a have a structure combined with each other. With such a configuration, the frame 19 and the storage case 20 operate as the vegetable compartment door 16a is opened and closed.
引出しレール21には、自閉装置(自閉部)27(例えば第一のバネ)が取り付けられている。自閉装置27は、野菜室扉16aの開扉寸法が所定寸法以下になると、フレーム19と連携または係合し、閉扉方向にドアを引き込むよう構成されている。
A self-closing device (self-closing portion) 27 (for example, a first spring) is attached to the drawer rail 21. The self-closing device 27 is configured to cooperate or engage with the frame 19 and pull the door in the closing direction when the opening size of the vegetable compartment door 16a is equal to or smaller than a predetermined size.
より具体的には、自閉装置27は、野菜室扉16aの閉扉速度が所定速度以上になったときに閉扉速度を減速させる減速部と、野菜室扉16aの閉扉直前に閉扉速度を加速させる加速部を有する。例えば、自閉装置27は、図8(a)~図8(d)に示すように、ダンパ機構30で構成された減速部と、第一のバネ31を有する加速部とで構成されている。また、自閉装置27は、野菜室扉16aの開閉方向に可動自在の第一の凹部32、および、野菜室扉16aの開閉方向に可動自在の第二の凹部33を有する。第一の凹部32および第二の凹部33は、第二の凹部33に第一の凹部32が係合するよう、構成されている。第一のバネ31は、第一の凹部32を閉扉方向に引き込むように構成されている。ダンパ機構30は、第二の凹部33の閉扉方向の動きを抑制するように構成されている。自閉装置27は、野菜室扉16aの開扉寸法が所定寸法以上では、図8(a)に示すように、フレーム19の凸部19aと第一の凹部32とは係合していないが、野菜室扉16aの開扉寸法が所定寸法以下では、図8(b)に示すように、フレーム19の凸部19aと第一の凹部32とが係合し、野菜室扉16aを閉扉方向に引き込むように構成されている。また、野菜室扉16aの開扉寸法が所定寸法から閉扉直前までは、図8(c)に示すように、第一の凹部32と第二の凹部33は係合している。このため、野菜室扉16aの開扉寸法が所定寸法から閉扉直前までは、第二の凹部33の閉扉方向の動きを抑制するダンパ機構30(減速部)により、第一のバネ31の引き込みによる閉扉速度が抑制されている。第一の凹部32は、野菜室扉16aの閉扉直前に、図8(d)に示すように、凸部19aと係合したまま、第二の凹部33との係合が外れるように構成されている。このような構成により、第二の凹部33に作用していたダンパ機構30による引き込みの抑制がなくなり、第一のバネ31(加速部)による第一の凹部32の引き込みのみとなるため、閉扉速度が加速される。このように、自閉装置27は、加速部としても機能するよう構成されている。
More specifically, the self-closing device 27 accelerates the closing speed immediately before the vegetable compartment door 16a is closed, and a deceleration unit that reduces the closing speed when the closing speed of the vegetable compartment door 16a is equal to or higher than a predetermined speed. It has an acceleration part. For example, as shown in FIGS. 8A to 8D, the self-closing device 27 is configured by a speed reduction portion configured by a damper mechanism 30 and an acceleration portion having a first spring 31. . The self-closing device 27 includes a first recess 32 that is movable in the opening / closing direction of the vegetable compartment door 16a and a second recess 33 that is movable in the opening / closing direction of the vegetable compartment door 16a. The first recess 32 and the second recess 33 are configured such that the first recess 32 engages with the second recess 33. The first spring 31 is configured to draw the first recess 32 in the door closing direction. The damper mechanism 30 is configured to suppress the movement of the second recess 33 in the door closing direction. In the self-closing device 27, when the opening size of the vegetable compartment door 16a is equal to or larger than the predetermined size, the convex portion 19a of the frame 19 and the first concave portion 32 are not engaged as shown in FIG. When the opening size of the vegetable compartment door 16a is equal to or smaller than the predetermined size, as shown in FIG. 8B, the convex portion 19a of the frame 19 and the first concave portion 32 are engaged, and the vegetable compartment door 16a is closed. It is configured to be pulled into. Moreover, as shown in FIG.8 (c), the 1st recessed part 32 and the 2nd recessed part 33 are engaging until the opening dimension of the vegetable compartment door 16a is from a predetermined dimension to just before closing. For this reason, by the damper mechanism 30 (deceleration part) which suppresses the movement of the 2nd recessed part 33 in the door closing direction until the door opening dimension of the vegetable compartment door 16a is from a predetermined dimension to just before door closing, it is by pulling in of the 1st spring 31. The closing speed is suppressed. As shown in FIG. 8 (d), the first recess 32 is configured to be disengaged from the second recess 33 while being engaged with the projection 19a immediately before the vegetable compartment door 16a is closed. ing. With such a configuration, the pull-in suppression by the damper mechanism 30 acting on the second concave portion 33 is eliminated, and only the first concave portion 32 is pulled in by the first spring 31 (acceleration portion). Is accelerated. Thus, the self-closing device 27 is configured to function also as an acceleration unit.
また、変形例として、自閉装置27は、以下のように構成されていてもよい。第二の凹部33は、第一の凹部32の閉扉方向の可動域の延長線上に設けられ、第二の凹部33に第二のバネ(図示なし)が設けられて、野菜室扉6aを閉扉方向に引き込むように構成されていてもよい。この場合、第一のバネ31は、第一の凹部32を閉扉方向に引き込むように構成されている。ダンパ機構30は、第一のバネ31による第一の凹部32の引き込みを抑制するように構成されていている。この場合、自閉装置27は、野菜室扉16aの開扉寸法が所定寸法以上では、フレーム19の凸部19aと第一の凹部32は係合していないが、野菜室扉16aの開扉寸法が所定寸法以下では、フレーム19の凸部19aと第一の凹部32とが係合し、閉扉方向に野菜室扉16aを引き込むように構成されていてもよい。また、野菜室扉16aの開扉寸法が所定寸法から閉扉直前までは、フレーム19の凸部19aと第一の凹部32とが係合し、閉扉方向に野菜室扉16a第一の凹部32とは係合している。このため、野菜室扉16aの開扉寸法が所定寸法から閉扉直前までは、第一の凹部32の閉扉方向の動きを抑制するダンパ機構30により、第一のバネ31の引き込みによる閉扉速度が抑制されている。野菜室扉16aの閉扉直前に、フレーム19の凸部19aは、第一の凹部32との係合が外れるとともに、第二の凹部33に係合するように構成されていてもよい。このような構成により、フレーム19の凸部19aは、ダンパ機構30による引き込みの抑制がなくなり、第二の凹部33に設けられた第二のバネによる引き込みにより、野菜室扉16aの閉扉速度が加速される。
As a modification, the self-closing device 27 may be configured as follows. The second recess 33 is provided on an extension of the movable range in the door closing direction of the first recess 32, and a second spring (not shown) is provided in the second recess 33 to close the vegetable compartment door 6a. It may be configured to pull in the direction. In this case, the first spring 31 is configured to draw the first recess 32 in the door closing direction. The damper mechanism 30 is configured to suppress the first recess 32 from being pulled in by the first spring 31. In this case, in the self-closing device 27, when the opening size of the vegetable compartment door 16a is equal to or larger than the predetermined size, the convex portion 19a of the frame 19 and the first concave portion 32 are not engaged, but the vegetable compartment door 16a is opened. If the dimension is equal to or smaller than the predetermined dimension, the convex portion 19a of the frame 19 and the first concave portion 32 may be engaged with each other, and the vegetable compartment door 16a may be drawn in the door closing direction. Moreover, the convex part 19a of the flame | frame 19 and the 1st recessed part 32 engage until the door opening dimension of the vegetable compartment door 16a is just from a predetermined dimension to a door closing, and the vegetable compartment door 16a 1st recessed part 32 and the door direction are closed. Are engaged. For this reason, until the door opening dimension of the vegetable compartment door 16a is from a predetermined dimension to immediately before closing, the damper mechanism 30 that suppresses the movement of the first recess 32 in the door closing direction suppresses the door closing speed due to the pulling of the first spring 31. Has been. Immediately before the vegetable compartment door 16a is closed, the convex portion 19a of the frame 19 may be configured to be disengaged from the first concave portion 32 and to be engaged with the second concave portion 33. With such a configuration, the convex portion 19a of the frame 19 is not restrained from being pulled in by the damper mechanism 30, and the closing speed of the vegetable compartment door 16a is accelerated by the pulling in by the second spring provided in the second concave portion 33. Is done.
野菜室扉16aは、弾性のある材料で構成されたガスケット28を有する。ガスケット28は、野菜室扉16aと筐体11との隙間を密閉する役割を担う。ガスケット28は、野菜室扉16aの密閉時には、自閉装置27の引き込み力によって、ガスケット28が筐体11の開口部に接触していないときの状態と比べて、0.2mm以上圧縮された状態となる。ガスケット28がこのように圧縮されることで、ガスケット28が外気に触れる面積を低減できるので、外部から野菜室16内に侵入する熱量も抑制することが可能となる。
The vegetable compartment door 16a has a gasket 28 made of an elastic material. The gasket 28 plays a role of sealing a gap between the vegetable compartment door 16a and the housing 11. When the vegetable compartment door 16a is sealed, the gasket 28 is compressed by 0.2 mm or more compared to the state when the gasket 28 is not in contact with the opening of the housing 11 by the pulling force of the self-closing device 27. It becomes. Since the gasket 28 is compressed in this manner, the area where the gasket 28 is exposed to the outside air can be reduced, so that it is possible to suppress the amount of heat that enters the vegetable compartment 16 from the outside.
以下、図2から図6を用いて、さらに自閉装置27による閉扉動作を説明する。
Hereinafter, the closing operation by the self-closing device 27 will be described with reference to FIGS.
図2では、野菜室16が開扉状態にあり、その開扉量はD0である。開扉量(開扉寸法)は、野菜室16の前面から、野菜室扉16aのガスケット28の、野菜室16側の表面までの距離(寸法)で表される。使用者は、開扉量D0からD1(図5参照)となるまで手動で野菜室扉16aを閉扉方向に操作する。これにより、閉扉速度はV1(図5参照)まで加速される。
In FIG. 2, the vegetable compartment 16 is in an open state, and the door opening amount is D0. The door opening amount (door opening dimension) is represented by the distance (dimension) from the front surface of the vegetable compartment 16 to the surface of the gasket 28 of the vegetable compartment door 16a on the vegetable compartment 16 side. The user manually operates the vegetable compartment door 16a in the door closing direction until the door opening amount D0 becomes D1 (see FIG. 5). Thereby, the door closing speed is accelerated to V1 (see FIG. 5).
その後、野菜室扉16aは、惰性で閉扉され、レール21とフレーム19との摩擦によって少しずつ減速していき、図3に示すように、開扉量がD2となったときに閉扉速度はV2(図5参照)となる。自閉装置27は、この時点からドア引き込み作用を発生させる。
Thereafter, the vegetable compartment door 16a is closed by inertia and gradually decelerates due to friction between the rail 21 and the frame 19, and as shown in FIG. 3, when the door opening amount becomes D2, the closing speed is V2. (See FIG. 5). The self-closing device 27 generates a door retracting action from this point.
閉扉速度V2とそれに加わる自閉装置27のドア引き込み作用による引き込み力によって、残りの開扉量D2が閉扉される。野菜室扉16aが完全に閉扉されるとき、野菜室扉16aと筐体11との接触で大きな衝撃が発生し、その衝撃は、野菜室16内の食品同士を接触させ、食品を傷める可能性がある。また、野菜室扉16a上部と冷凍室扉15a下部との隙間C1(図3参照)に使用者の指が挟まる可能性もある。よって、減速部による減速作用が、隙間C1が例えば100mm以下となった時点で発生するように構成されており、隙間C1が10~20mm程度になったときには指が挟まらない程度に十分に減速されるよう構成されている。本実施の形態では、減速部によるこの減速作用には、シリコンオイル等を使用したダンパ機構が利用されているが、これに限られない。
The remaining door opening amount D2 is closed by the closing speed V2 and the pulling force due to the pulling action of the self-closing device 27 applied thereto. When the vegetable compartment door 16a is completely closed, a large impact is generated by the contact between the vegetable compartment door 16a and the housing 11, and the impact may cause food in the vegetable compartment 16 to contact each other and damage food. There is. In addition, a user's finger may be caught in a gap C1 (see FIG. 3) between the upper part of the vegetable compartment door 16a and the lower part of the freezer compartment door 15a. Therefore, the speed reducing action by the speed reducing portion is configured to occur when the gap C1 becomes, for example, 100 mm or less, and the speed is sufficiently reduced so that the finger is not caught when the gap C1 becomes about 10 to 20 mm. It is configured to be. In the present embodiment, a damper mechanism using silicon oil or the like is used for the deceleration action by the deceleration unit, but is not limited thereto.
このように、自閉装置27は、開扉量がD2となった時点(第2の位置)から、ドア引き込み作用を発生させる。これに伴い、閉扉速度V2は減速される。減速部による減速作用は、図4に示すように、開扉量D3となるまで継続される。このときの閉扉速度はV3(図5参照)となっている。
Thus, the self-closing device 27 generates a door pull-in action from the point in time when the door opening amount becomes D2 (second position). Accordingly, the door closing speed V2 is decelerated. The deceleration action by the deceleration unit is continued until the door opening amount D3 is reached, as shown in FIG. The closing speed at this time is V3 (see FIG. 5).
もし、閉扉速度V3以下のまま、残りの開扉量D3が閉扉されるとき、野菜室16内の収納物重量が重い場合は、レール21とフレーム19との摩擦によって、更に閉扉速度が低下し、図6Aに示すような閉じ方となる。図6Aの寸法C2は、ガスケット28が殆んど圧縮されない状態、すなわち、ガスケット28が筐体11の開口部に接触していない状態でのガスケット28の厚み寸法から0.2mmを引いた値より大きい寸法(圧縮代が0.2mm以下)となっている。このため、ガスケット28の外気に触れる面積を十分に低減できず、外部から野菜室16内に侵入する熱量抑制効果が殆ど得られない。このため、閉扉状態は、図6Bの寸法C3のように、ガスケット28が筐体11の開口部に接触していない状態での寸法から0.2mmを引いた値より小さい寸法まで(圧縮代が0.2mm以上)圧縮されていることが望ましい。
If the remaining door opening amount D3 is closed with the door closing speed V3 or less, and the weight of the stored item in the vegetable compartment 16 is heavy, the door closing speed is further reduced due to friction between the rail 21 and the frame 19. The closing method is as shown in FIG. 6A. The dimension C2 in FIG. 6A is a value obtained by subtracting 0.2 mm from the thickness dimension of the gasket 28 in a state where the gasket 28 is hardly compressed, that is, in a state where the gasket 28 is not in contact with the opening of the housing 11. The dimensions are large (compression allowance is 0.2 mm or less). For this reason, the area of the gasket 28 exposed to the outside air cannot be sufficiently reduced, and the effect of suppressing the amount of heat entering the vegetable compartment 16 from the outside can hardly be obtained. For this reason, the closed state is a dimension smaller than the value obtained by subtracting 0.2 mm from the dimension in the state where the gasket 28 is not in contact with the opening of the housing 11 as in the dimension C3 in FIG. It is desirable that it is compressed (0.2 mm or more).
よって、開扉量D3(図4参照)となった時点(第1の位置)で、自閉装置27は、閉扉速度を加速させる(図5参照)。密閉時の閉扉速度は、大きな衝撃が発生しない程度のV4(図5参照)となっており、ガスケット28は、寸法C3まで確実に圧縮され、野菜室16内に侵入する熱量も抑制することが可能となる。
Therefore, at the time (first position) when the door opening amount D3 (see FIG. 4) is reached, the self-closing device 27 accelerates the door closing speed (see FIG. 5). The closing speed at the time of sealing is V4 (see FIG. 5) that does not cause a large impact, and the gasket 28 is reliably compressed to the dimension C3, and the amount of heat entering the vegetable compartment 16 is also suppressed. It becomes possible.
また、密閉直前に閉扉速度を加速し、密閉時に野菜室扉16aと筐体11との接触に伴うパタンという接触音を発生させることで、使用者に、野菜室扉16aが確実に閉じられたことを知らせることができる。
Moreover, the door closing speed was accelerated immediately before sealing, and the vegetable chamber door 16a was reliably closed to the user by generating a contact sound called a pattern accompanying the contact between the vegetable chamber door 16a and the housing 11 at the time of sealing. I can let you know.
また、閉扉速度の加速が開始される開扉量D3は、野菜室扉16a上部と冷凍室扉15a下部との隙間C1が発生しない地点に設定されているため(図3および図4参照)、自閉装置27による加速作用で使用者の指が挟まれるようなことも回避できる。
Moreover, the opening amount D3 at which acceleration of the closing speed is started is set at a point where the gap C1 between the upper part of the vegetable compartment door 16a and the lower part of the freezer compartment door 15a does not occur (see FIGS. 3 and 4). It is also possible to avoid the user's finger being pinched by the acceleration action of the self-closing device 27.
なお、野菜室扉16aが密閉状態でも、自閉装置27の引き込み力は作用しており、自閉装置27は、開扉を妨げない10N前後の力で、フレーム19を閉じ方向に引き込んでいる。このような構成により、例えば冷蔵庫50の手前方向への傾きがあったとしても、野菜室扉16aの密閉状態は保持される。
In addition, even if the vegetable compartment door 16a is hermetically sealed, the pulling force of the self-closing device 27 is acting, and the self-closing device 27 pulls the frame 19 in the closing direction with a force of about 10 N that does not interfere with the opening of the door. . With such a configuration, for example, even if the refrigerator 50 is tilted toward the front, the sealed state of the vegetable compartment door 16a is maintained.
一方、図7に示すように、開扉量D0からD1となるまでの使用者による手動操作が弱く、初期閉扉速度がV11であったとする。
On the other hand, as shown in FIG. 7, it is assumed that the manual operation by the user from the door opening amount D0 to D1 is weak and the initial door closing speed is V11.
この場合は、その後、野菜室扉16aは惰性で閉扉され、レール21とフレーム19との摩擦によって少しずつ減速していき、開扉量がD2となったときに閉扉速度はV12となる(図7参照)。この閉扉速度V12のみでは、野菜室扉16aは、閉扉前に停止してしまう。しかしながら、自閉装置27がこの時点からドア引き込み作用を発生させるので、半ドア状態が防止される。
In this case, the vegetable compartment door 16a is then closed by inertia and gradually decelerates due to friction between the rail 21 and the frame 19, and when the door opening amount becomes D2, the closing speed becomes V12 (FIG. 7). With this door closing speed V12 alone, the vegetable compartment door 16a stops before closing. However, since the self-closing device 27 generates the door retracting action from this point, the half-door state is prevented.
なお、図5を参照して上記でも説明したように、使用者の指挟まりも防止するため、隙間C1が、指が挟まり得る10~20mm程度になるまで、自閉装置27による引き込み加速は、ダンパ機構によって制限されており、開扉量D3となるまで、閉扉速度はV13に抑制されている。
As described above with reference to FIG. 5, in order to prevent the user's fingers from being pinched, the retraction acceleration by the self-closing device 27 is performed until the gap C1 reaches about 10 to 20 mm where the fingers can be pinched. The door closing speed is limited to V13 until the door opening amount D3 is limited by the damper mechanism.
さらに、閉扉状態において、図6Bの寸法C3のように、ガスケット28を非密閉時のガスケット28の厚み寸法から0.2mm引いた値より小さい寸法まで圧縮させるため、開扉量D3となった時点で、自閉装置27は、閉扉速度を加速させる。密閉時の閉扉速度は、大きな衝撃が発生しない程度のV14(図7参照)となっており、ガスケット28は、寸法C3まで確実に圧縮され、野菜室16内に侵入する熱量も抑制することが可能となる。
Furthermore, in the closed state, as shown by the dimension C3 in FIG. 6B, the gasket 28 is compressed to a dimension smaller than the value obtained by subtracting 0.2 mm from the thickness dimension of the gasket 28 in the non-sealed state. Thus, the self-closing device 27 accelerates the door closing speed. The closing speed at the time of sealing is V14 (see FIG. 7) that does not generate a large impact, and the gasket 28 is reliably compressed to the dimension C3, and the amount of heat entering the vegetable compartment 16 can also be suppressed. It becomes possible.
閉扉速度V3と閉扉速度V13は、同等の速度となっており、閉扉速度V4と閉扉速度V14は、同等の速度となっている。これらの閉扉速度は、使用者が印加する初期速度に関わらず、ほぼ一定となる。
The closing speed V3 and the closing speed V13 are equivalent speeds, and the closing speed V4 and the closing speed V14 are equivalent speeds. These closing speeds are almost constant regardless of the initial speed applied by the user.
以上述べたように、本実施の形態によれば、自閉装置27の減速部による閉扉速度の減速によって使用者の指挟まりおよび食品への衝撃を防止できるとともに、閉扉速度の減速によって閉扉速度が低下し過ぎた場合でも、加速部により閉扉速度が再加速される。よって、本実施の形態によれば、確実な密閉ができ、閉扉時の衝撃緩和と確実な密閉との両立が可能となる。
As described above, according to the present embodiment, it is possible to prevent a user from pinching and impacting food by reducing the closing speed by the speed reducing unit of the self-closing device 27, and the closing speed is reduced by reducing the closing speed. Even if it decreases too much, the closing speed is re-accelerated by the acceleration unit. Therefore, according to the present embodiment, reliable sealing can be performed, and it is possible to achieve both relaxation of the impact when the door is closed and reliable sealing.
なお、本実施の形態の自閉装置27は、野菜室扉16aに限られず、他の扉にも適用できる。また、引出し式の扉に限られず、ヒンジを使用した回動式の扉においても、本開示の閉扉速度の減速および加速の考え方は適用可能である。
In addition, the self-closing device 27 of this Embodiment is not restricted to the vegetable compartment door 16a, It can apply also to another door. Moreover, the concept of deceleration and acceleration of the door closing speed of the present disclosure is applicable not only to a drawer type door but also to a rotary type door using a hinge.
また、本実施の形態の自閉装置27は、野菜室扉16aのレール21の左右両方に設置されてもよいし、いずれか一方に設置されてもよい。
Also, the self-closing device 27 of the present embodiment may be installed on both the left and right sides of the rail 21 of the vegetable compartment door 16a, or may be installed on either one.
また、自閉装置27が設置されるレール21は、収納ケース20の下部で、野菜室扉16aの下部に設置されることが望ましい。これにより、収納ケース20の支持が収納ケース20の下部で行なわれることができ、収納ケース20の実効内容積を高めることができる。
Also, it is desirable that the rail 21 on which the self-closing device 27 is installed is installed at the lower part of the storage case 20 and at the lower part of the vegetable compartment door 16a. Thereby, support of storage case 20 can be performed in the lower part of storage case 20, and the effective internal volume of storage case 20 can be raised.
本開示は、扉および収納室に加わる負荷、並びに、周囲温度等の影響に関わらず、閉扉時の衝撃緩和と確実な密閉とを両立させることができる冷蔵庫を提供する。よって、家庭用および業務用の冷蔵庫、並びに、温調が不要な収納庫等にも応用できる。
The present disclosure provides a refrigerator that can achieve both impact mitigation and reliable sealing when the door is closed, regardless of the influence of the load applied to the door and the storage room and the ambient temperature. Therefore, it can be applied to refrigerators for home use and business use, and storages that do not require temperature control.
