Description

本発明は、貯蔵室内に引き出し容器を設けた冷蔵庫に係り、特に引き出し容器の扉スイッチ構成に関する。   The present invention relates to a refrigerator provided with a drawer container in a storage chamber, and more particularly to a door switch configuration of the drawer container.

従来、冷蔵庫の貯蔵室中、最も収納容積の大きな冷蔵室を除いて、その下方に配置されている野菜室や冷凍室などの貯蔵室は、使い勝手の面から開口部に設けた扉に支持枠を固着し、これに収納容器を載置して引き出し自在とした、いわゆる引き出し扉方式を採用することが主流となっている。   Conventionally, storage rooms such as a vegetable room and a freezer room, which are arranged below the storage room of the refrigerator, except for the refrigeration room with the largest storage capacity, have a support frame on the door provided at the opening from the viewpoint of ease of use. Adopting a so-called drawer door system, in which the storage container is placed on the storage container and can be pulled out, has become the mainstream.

中でも、図７、図８に示すように、自動製氷機（59）を配置し貯氷容器（60）を備えた製氷室（57）などの比較的貯蔵容積が少なく、また開閉扉力が軽い引き出し扉における開閉扉を検知する扉スイッチ（66）は、扉（61）の内面に埋設したマグネット（70）の磁力で接点を開閉するリードスイッチタイプを採用して製氷室の開口仕切部（65）に設置されており、開扉時には扉側のマグネット（70）が扉スイッチ（66）部分から離間することでリードスイッチ（66ａ）を動作させ、冷却ファンや製氷動作を停止するように制御していた。（例えば、特許文献１参照）
特開２００１−１７４１４５公報 Among them, as shown in Fig. 7 and Fig. 8, there is a drawer with a relatively small storage volume, such as an ice making chamber (57) equipped with an automatic ice maker (59) and an ice storage container (60), and a light opening and closing door force. The door switch (66) that detects the open / close door of the door adopts a reed switch type that opens and closes the contact by the magnetic force of the magnet (70) embedded in the inner surface of the door (61), and the ice compartment opening partition (65) The door side magnet (70) is moved away from the door switch (66) when the door is opened, and the reed switch (66a) is operated to stop the cooling fan and ice making operation. It was. (For example, see Patent Document 1)
JP 2001-174145 A

しかしながら、前記リードスイッチ（66ａ）は高価であるばかりでなく、開口仕切部（65）における残留磁気により開扉を検知しないなど誤動作する問題がある。これを解決するためには機械式の押釦スイッチ方式を採用すればよいが、前記製氷室（57）は収納容積が小さく重量が軽いため、例えば、図９に示すように、製氷扉（61）の内板に固定した貯氷容器（60）を支持する支持枠（62）に、自閉のための傾斜（62ａ）による閉扉機構を設けていても、押釦スイッチのバネ力に対して容器を含めた扉の閉扉力が弱いことから、閉扉時の動作によっては完全に閉扉せず半ドア状態となる可能性があった。   However, the reed switch (66a) is not only expensive, but also has a problem of malfunction such as not detecting the opening due to residual magnetism in the opening partition (65). In order to solve this, a mechanical push button switch method may be adopted. However, since the ice making chamber (57) has a small storage volume and light weight, for example, as shown in FIG. 9, an ice making door (61) Even if the support frame (62) that supports the ice storage container (60) fixed to the inner plate of the door is provided with a door closing mechanism with an inclination (62a) for self-closing, the container is included against the spring force of the pushbutton switch. Due to the weak closing force of the door, depending on the operation at the time of closing, there was a possibility that the door would not be closed completely and a half-door state could occur.

また、閉扉をより確実にするために押釦スイッチのバネ力を弱くすることも考えられるが、前記バネ力は開閉による繊細な押圧動作に対応させるため、既に極限まで弱くしていることと、バネを設置している製氷室は冷凍温度であることから、その低温雰囲気によって、閉扉の後に再び開扉したときにバネが伸長状態に復帰せず、やはり誤動作が発生する問題があった。   It is also conceivable to weaken the spring force of the pushbutton switch in order to make the door more secure, but the spring force has already been weakened to the limit in order to cope with the delicate pressing operation by opening and closing, and the spring Since the ice making chamber in which is installed is at a freezing temperature, the spring does not return to the extended state when the door is opened again after closing due to its low temperature atmosphere, which also causes a malfunction.

本発明は上記点を考慮してなされたものであり、引き出し扉における扉スイッチとして機械式の押釦スイッチを用いるとともに、扉スイッチの誤動作を防止し、確実な閉扉をおこなうことができる冷蔵庫を提供することを目的とする。   The present invention has been made in consideration of the above points, and provides a refrigerator that can use a mechanical push button switch as a door switch in a drawer door, prevent malfunction of the door switch, and perform reliable door closing. For the purpose.

上記課題を解決するために、本発明の冷蔵庫は、貯蔵室の開口部に容器の摺動支持枠とレールによる引き出し方式によって開閉自在に設けられた扉と、この扉の開閉による本体側開口部との離接を検知して動作する開口部近傍に設けられた圧縮コイルバネによる押釦機構の扉スイッチと、前記扉の最終閉扉位置で本体側と係合する摺動支持枠に設けられた自閉用傾斜に続く落とし込み段落とからなり、前記圧縮コイルバネのバネ部の長さを長くすることで、前記落とし込み段落による閉扉力よりもバネ力を小さくしたことを特徴とするものである。   In order to solve the above problems, a refrigerator according to the present invention includes a door provided in an opening portion of a storage room so as to be opened and closed by a sliding support frame of a container and a rail, and a main body side opening portion by opening and closing the door. The door switch of the push button mechanism with a compression coil spring provided near the opening that operates by detecting separation and contact with the door, and the self-closing provided on the sliding support frame that engages with the main body at the final closing position of the door The spring force is made smaller than the closing force by the dropping paragraph by increasing the length of the spring portion of the compression coil spring.

この構成によって、リードスイッチタイプの扉スイッチにおける残留磁気による制御装置の誤動作を防ぎ、機械式押釦方式の扉スイッチの採用によってコストを低減できるとともに、コイルバネのバネ力を低減して扉スイッチ機能を保持したままで自閉力を強くすることにより確実な閉扉をおこなうことができる。   This configuration prevents malfunction of the control device due to remanent magnetism in the reed switch type door switch, and can reduce the cost by adopting the mechanical push button type door switch, and also keep the door switch function by reducing the spring force of the coil spring. The door can be reliably closed by strengthening the self-closing force while keeping it.

以下、図面に基づき本発明の１実施形態について説明する。冷蔵庫要部の縦断面図である図１、および該部の斜視図である図２に示すように、冷蔵庫（１）は、外箱（２）の内面に断熱材（３）を介して設けた内箱（４）により貯蔵空間を形成し、仕切壁（５）により複数の貯蔵室に区分している。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 which is a longitudinal sectional view of the main part of the refrigerator and FIG. 2 which is a perspective view of the main part, the refrigerator (1) is provided on the inner surface of the outer box (2) via a heat insulating material (3). A storage space is formed by the inner box (4) and divided into a plurality of storage chambers by the partition wall (5).

本体の最上部には、ヒンジにより本体一側に回動自在に冷蔵室扉を枢支してその前面開口部を閉塞した図示しない冷蔵室を配置しており、冷蔵室の下部には、野菜などを収納する野菜室（６）、野菜室（６）の下方には、断熱仕切壁（５）を介して比較的小容積の製氷室（７）と図示しない温度切替室を併置し、最下部には冷凍食品を収納する冷凍室（８）を配している。   At the top of the main body, there is a cold room (not shown) that pivots on the side of the main body by a hinge and closes its front opening by a hinge. A relatively small-sized ice making chamber (7) and a temperature switching chamber (not shown) are placed below the vegetable chamber (6) and the vegetable chamber (6) through the heat insulating partition wall (5). The freezer compartment (8) which stores frozen food is arranged in the lower part.

上記冷蔵室以外のこれら貯蔵室は、その前面開口を閉塞する扉の庫内側に支持枠を設け、この支持枠に保持した収納容器を各貯蔵室側壁に配置したレールによって前後摺動可能とした引き出し方式としている。   These storage rooms other than the refrigerator compartment are provided with a support frame on the inner side of the door that closes the front opening, and the storage containers held by the support frame can be slid forward and backward by rails arranged on the side walls of the respective storage rooms. It is a drawer system.

前記製氷室（７）は、冷蔵室に設けた給水タンクからの給水を受けて製氷する製氷皿を設けた自動製氷装置（９）を設置するとともに、製氷完了時に製氷皿を反転離氷して氷塊を受ける貯氷容器（10）を具備しており、この貯氷容器（10）は製氷室（７）の前面開口部を閉塞する製氷室扉（11）の内側に取り付けた支持枠（12）に保持されている。   The ice making chamber (7) is provided with an automatic ice making device (9) provided with an ice making tray for making ice upon receiving water from a water supply tank provided in the refrigerator compartment, and when the ice making is completed, the ice making tray is inverted and deiced. An ice storage container (10) for receiving ice blocks is provided, and this ice storage container (10) is attached to a support frame (12) attached to the inside of the ice making chamber door (11) that closes the front opening of the ice making chamber (7). Is retained.

支持枠（12）は、製氷室（７）の両側壁に配置したレール（７ａ） 内を回動するローラー（14）を後端に設け、前後方向に摺動して製氷室扉（11）と一体に引き出し自在に取り付けられている。   The support frame (12) is provided with a roller (14) that rotates in rails (7a) arranged on both side walls of the ice making chamber (7) at the rear end, and slides in the front-rear direction to make the ice making chamber door (11) And can be pulled out together.

しかして、前記支持枠（12）の製氷室扉（11）近傍の下面には、概略詳細を図３に示すように、製氷室扉（11）を閉扉する最終段階で開口部近傍の貯蔵室底面に設けた円弧状のガイド突起（13）と係合して、製氷室扉（11）とともに支持枠（12）を、それら自らの重量によって自動的に閉扉させるための自閉傾斜（12ａ）を形成している。この自閉傾斜（12ａ）は前方に向かって５度程度の上り勾配を有しており、この自閉傾斜の前方に連続して１０数度のさらに前方へ１０数度の勾配を有して上る落とし込み傾斜（12ｂ）を形成している。   Then, on the lower surface of the support frame (12) in the vicinity of the ice making chamber door (11), as shown in FIG. 3, the storage chamber in the vicinity of the opening is closed at the final stage of closing the ice making chamber door (11). Self-closing slope (12a) for engaging the arcuate guide protrusion (13) provided on the bottom surface and automatically closing the supporting frame (12) together with the ice making chamber door (11) by their own weight Is forming. This self-closing slope (12a) has an upward slope of about 5 degrees toward the front, and has a slope of 10-degree degrees further forward by 10 and several degrees in front of the self-closed slope. A rising slope (12b) is formed.

前記ガイド突起（13）は、支持枠（12）の円滑な摺動をはかるために円弧状に形成しており、製氷室底面部材と一体に形成しているが、滑りの良い別ピースによってより円滑に摺動させるようにしてもよく、さらには回転ローラを取り付けてこれに支持枠（12）を係合させるようにしてもよい。   The guide protrusion (13) is formed in an arc shape for smooth sliding of the support frame (12), and is formed integrally with the ice making chamber bottom member. You may make it slide smoothly, and also you may make it attach a support frame (12) to this by attaching a rotation roller.

したがって、閉扉の際には、製氷室扉（11）および貯氷容器（10）は、ローラー（14）がレール（７ａ）内を摺動する支持枠（12）とともに製氷室（７）の奥方に向かって移動し、最終段階では、前記自閉傾斜（12ａ）と前記ガイド突起（13）との係合によって、製氷室扉（11）は自動的に閉扉する方向に摺動し、自閉傾斜（12ａ）に続く落とし込み傾斜（12ｂ）との係合で支持枠（12）が室内後方に向かって落とし込まれることになり、これによって、自閉の引き込み力は従来の約０．７５Ｎから約２Ｎに増加し、製氷室扉（11）も後方に引き込まれて確実に閉扉するものであり、製氷室扉（11）の周縁に取り付けたガスケット（11ａ）が製氷室（７）の開口周縁に当接して製氷室（７）内を気密に閉塞する。   Therefore, when the door is closed, the ice making chamber door (11) and the ice storage container (10) are placed at the back of the ice making chamber (7) together with the support frame (12) in which the roller (14) slides in the rail (7a). In the final stage, the ice making door (11) automatically slides in the closing direction due to the engagement between the self-closing inclination (12a) and the guide protrusion (13), and the self-closing inclination. The support frame (12) is dropped toward the rear of the room due to the engagement with the drop slope (12b) following (12a), so that the self-closing pull-in force is about 0.75 N from the conventional value of about 0.75 N. The ice making chamber door (11) is also pulled back to close securely and the gasket (11a) attached to the periphery of the ice making chamber door (11) is attached to the opening periphery of the ice making chamber (7). The ice making chamber (7) is airtightly closed by abutting.

製氷室（７）の開口部における前記隣接する温度切替室との縦仕切板（15）には、扉スイッチ（16）を配設している。扉スイッチ（16）は、詳細構造を図４に示すように、機械式である押釦スイッチ方式であって、前記縦仕切板（15）から製氷装置の前方側へ突出しているスイッチ取り付け部（17）に取り付けられており、スイッチケース（16ａ）から出没する作動子（16ｂ）の移動によってケース（16ａ）内に設けた複数の接続端子（16ｃ）の接点を導通させる既存の構成であり、作動子（16ｂ）の位置により冷却ファンや製氷動作の駆動制御をおこなうものである。   A door switch (16) is disposed on the vertical partition plate (15) with the adjacent temperature switching chamber at the opening of the ice making chamber (7). As shown in FIG. 4, the door switch (16) is a mechanical push button switch type, and has a switch mounting portion (17) protruding from the vertical partition plate (15) to the front side of the ice making device. ), And is an existing configuration in which the contacts of the plurality of connection terminals (16c) provided in the case (16a) are made conductive by the movement of the actuator (16b) protruding and retracting from the switch case (16a) The drive of the cooling fan and ice making operation is controlled by the position of the child (16b).

そして、前記扉スイッチ（16）は、その作動子（16ｂ）が圧縮コイルバネ（16ｄ）により常時製氷室（７）の前方に突出するように付勢されており、製氷室扉（11）が閉扉状態にあるときは、図５に示すように、扉内板（11ｂ）が作動子（16ｂ）に当接してコイルバネ（16ｄ）の付勢力に抗してこれを後方へ押し込み、冷却ファンや製氷装置の回路を接続して所定の制御運転をおこなものであり、開扉によって扉内板（11ｂ）の押圧力が解除されると、図４に示すように、作動子（16ｂ）が前方移動して、前記冷却ファンや製氷装置の回路を遮断し、ファンの回転を停止して冷気の流出を防止するとともに製氷装置の給水や離氷回転動作をおこなわせないようにしている。   The door switch (16) is urged so that its actuator (16b) always protrudes forward of the ice making chamber (7) by the compression coil spring (16d), and the ice making door (11) is closed. When in this state, as shown in FIG. 5, the door inner plate (11b) abuts against the actuator (16b) and pushes it backward against the urging force of the coil spring (16d). The circuit of the device is connected to perform a predetermined control operation. When the pressing force of the door inner plate (11b) is released by the door opening, the actuator (16b) is moved forward as shown in FIG. The circuit of the cooling fan and the ice making device is shut off and the rotation of the fan is stopped to prevent the outflow of cold air and the water supply and deicing rotation operations of the ice making device are not performed.

しかして、前記圧縮コイルバネ（16ｄ）は、前述したように、扉の閉扉力に対して強いことから、そのバネ力を従来より低くする必要がある。バネ力を低減するにはコイルの径を大きくすることも考えられるが、扉スイッチ（16）のコイルバネ（16ｄ）は作動子（１６ｂ）に内部に嵌入して伸縮するものであり、径が大きい作動子が開扉時に製氷室などの貯蔵室の表面に露出することは外観意匠上好ましいものではない。   Thus, as described above, the compression coil spring (16d) is strong against the door closing force, so that the spring force needs to be lower than that of the conventional one. Although it is conceivable to increase the diameter of the coil in order to reduce the spring force, the coil spring (16d) of the door switch (16) is fitted into the actuator (16b) to expand and contract, and has a large diameter. It is not preferable in terms of appearance design that the actuator is exposed to the surface of a storage room such as an ice making room when the door is opened.

本発明においては、バネ力を従来より低動作にして反発力を減らすために、コイル径とコイル巻き数を同等にして長さ寸法のみを長くしている。前記により低減したバネ力は、前記支持枠（12）の落とし込み傾斜（12ｂ）とガイド突起（13）との係合による引き込み力によって約２Ｎに増加させた閉扉力よりも小さくすることができる。   In the present invention, in order to reduce the repulsive force by lowering the spring force than the conventional one, only the length dimension is made long by making the coil diameter and the number of coil turns equal. The spring force reduced as described above can be made smaller than the closing force increased to about 2N by the pull-in force due to the engagement between the drop inclination (12b) of the support frame (12) and the guide protrusion (13).

しかしながら、バネ長を長くした結果として、スイッチケース（16ａ）内におけるバネの座屈が発生し易くなり動作不良やケースと接触することによる異音が起こることがあるため、本実施例では、コイルバネ（16ｄ）の後端基部にバネのコイル内に延出するように円錐形状の突条（17）設けて座屈を防止している。   However, as a result of increasing the spring length, the spring is likely to buckle in the switch case (16a), which may cause malfunction and abnormal noise due to contact with the case. A conical ridge (17) is provided at the rear end base of (16d) so as to extend into the coil of the spring to prevent buckling.

この円錐突条（17）により、バネ長さが長くなってもコイルバネ（16ｄ）は、ケース内で確実に保持されることになり、且つ、バネ力を低減できるので、小さく軽量の扉であってもバネの反発力によって扉が完全に閉まらず、半ドア状態になることを未然に防ぐことができるものである。   This conical ridge (17) ensures that the coil spring (16d) is securely held in the case even when the spring length is long, and the spring force can be reduced. However, it is possible to prevent the door from being completely closed by the repulsive force of the spring, and to be in a half-door state.

そして、閉扉状態から製氷室扉（11）を引き出し、開扉した場合には、扉スイッチ（16）は扉内板（11ｂ）による押圧力が解除されるため作動子（16ｂ）がコイルバネ（16ｄ）の復元力によって前方に摺動し、接続端子（16ｃ）の接点を切換導通して冷却ファンの回転とともに製氷動作を停止させるものである。   When the ice making chamber door (11) is pulled out from the closed state and opened, the door switch (16) is released from the pressing force by the door inner plate (11b), so that the actuator (16b) is turned into a coil spring (16d). ) Is restored by a restoring force, and the contact of the connection terminal (16c) is switched and connected to stop the ice making operation with the rotation of the cooling fan.

再び閉扉する場合には、製氷室扉（11）のガスケット（11ｂ）が製氷室（７）の開口部に当接する間際に、図６に示すように、扉内板（11ｂ）がスイッチ（16）の作動子（16ｂ）に接触してこれを後方へ押圧することになる。同時にレール（７ａ）内を摺動する支持枠（12）の自閉傾斜（12ａ）がガイド突起（13）に係合して製氷室内側に引き込まれ、さらに傾斜角度の大きい落とし込み傾斜（12ｂ）によって落とし込まれることで、図１に示す所定の位置となって確実に閉扉し、スイッチ（16）の作動子（16ｂ）も所定位置に押し込まれて制御動作を切り換えることになる。   When the door is closed again, as shown in FIG. 6, the door inner plate (11b) is connected to the switch (16) while the gasket (11b) of the ice making chamber door (11) contacts the opening of the ice making chamber (7). ) Is pressed against the actuator (16b). At the same time, the self-closing inclination (12a) of the support frame (12) sliding in the rail (7a) engages with the guide protrusion (13) and is drawn into the ice making chamber, and the dropping inclination (12b) having a larger inclination angle. 1, the door is reliably closed at the predetermined position shown in FIG. 1, and the actuator (16b) of the switch (16) is also pushed into the predetermined position to switch the control operation.

本発明は上記のように構成されており、リードスイッチを使用しないので、コストを低減できるとともに仕切板のの残留磁気によって誤動作することがなく、コイルバネのバネ力を低減して押釦式の扉スイッチ機能を保持したままで扉の自閉力を強くすることにより確実な閉扉をおこなうことができる。   Since the present invention is configured as described above and does not use a reed switch, the push button type door switch can be reduced by reducing the spring force of the coil spring without causing malfunction due to the residual magnetism of the partition plate. The door can be reliably closed by increasing the self-closing force of the door while maintaining the function.

なお、上記実施例においては、製氷室扉（11）を例にして説明したが、本発明の対象はこれに限るものではなく、野菜室や冷凍室など、他の引き出し式扉の扉スイッチや摺動支持枠構成にも適用できることは言うまでもない。   In the above embodiment, the ice making room door (11) has been described as an example. However, the object of the present invention is not limited to this, and other drawer type door switches such as a vegetable room and a freezing room, Needless to say, the present invention can also be applied to a sliding support frame configuration.

本発明によれば、貯蔵室の開口を開閉自在に閉塞する引き出し式扉の扉スイッチの動作、および閉扉を確実におこなうことができる冷蔵庫に利用することができる。   ADVANTAGE OF THE INVENTION According to this invention, it can utilize for the refrigerator which can perform reliably the operation | movement of the door switch of the drawer | drawing-out type door which obstruct | occludes the opening of a storage chamber openably, and can be closed.
