Description

冷蔵庫refrigerator
　本発明は冷蔵庫に関し、特に操作スイッチ部の構造に関するものである。 The present invention relates to a refrigerator, and more particularly to a structure of an operation switch unit.
　一般に、冷蔵庫には、扉の前面に冷却温度等を設定する操作スイッチ部が設けられている（例えば、特許文献１参照）。 Generally, the refrigerator is provided with an operation switch unit for setting a cooling temperature or the like on the front surface of the door (see, for example, Patent Document 1).
　図７は、特許文献１に記載された冷蔵庫の正面図である。図８は、従来の冷蔵庫の操作部を示す拡大断面図である。 FIG. 7 is a front view of the refrigerator described in Patent Document 1. FIG. FIG. 8 is an enlarged cross-sectional view showing an operation unit of a conventional refrigerator.
　図７、８に示されるように、従来の冷蔵庫は、扉１０１の前面に操作部１０２を有し、操作部１０２は操作スイッチ部１０３と表示部１０４とを有する。 7 and 8, the conventional refrigerator includes an operation unit 102 on the front surface of the door 101, and the operation unit 102 includes an operation switch unit 103 and a display unit 104.
　操作スイッチ部１０３に設けられたスイッチ１０５は、前面を覆う扉ガラス１０６に触れて操作する静電スイッチである。スイッチ１０５は、扉ガラス１０６との間隔が広くなるにつれ、その感度が低下する。 The switch 105 provided in the operation switch unit 103 is an electrostatic switch operated by touching the door glass 106 covering the front surface. The sensitivity of the switch 105 decreases as the distance from the door glass 106 increases.
　従来の冷蔵庫においては、スイッチ１０５を組み込んだスイッチ基板１０７が、弾性突起１０９が設けられたスイッチケース１０８に収容される。弾性突起１０９を、扉１０１に設けられた装着凹部１１０の底面壁１１１に弾接させると、矢印Ｑで示されるように、スイッチ基板１０７が扉ガラス１０６に押し付けられるように構成されている。 In a conventional refrigerator, a switch board 107 incorporating a switch 105 is accommodated in a switch case 108 provided with an elastic protrusion 109. When the elastic protrusion 109 is brought into elastic contact with the bottom wall 111 of the mounting recess 110 provided on the door 101, the switch substrate 107 is configured to be pressed against the door glass 106 as indicated by an arrow Q.
　この構造により、従来の冷蔵庫において、スイッチ１０５が扉ガラス１０６の内側面に密着させることで感度が確保され、操作ミスをなくすことが可能である。 With this structure, in the conventional refrigerator, the switch 105 is brought into close contact with the inner surface of the door glass 106, so that the sensitivity is ensured and an operation error can be eliminated.
　しかしながら、ガラスなどによってスイッチ１０５の表面を覆う従来の構成と異なり、エンブレムシートや合成樹脂板のように、弾性変形可能なカバーを用いると、操作によってスイッチ部が破損する恐れがある。 However, unlike the conventional configuration in which the surface of the switch 105 is covered with glass or the like, if an elastically deformable cover such as an emblem sheet or a synthetic resin plate is used, the switch part may be damaged by the operation.
　具体的には、ユーザにより強く押圧されたスイッチ１０５が、スイッチ基板１０７を支える弾性突起１０９を大きく変形させながら、スイッチ基板１０７を強く押し込む。その結果、スイッチ基板１０７が取り付け部から外れたり、スイッチ１０５に接続される結線用の金属箔が切断されたりする等、スイッチ部に不具合や破損が生じる。 Specifically, the switch 105 strongly pressed by the user pushes the switch board 107 strongly while greatly deforming the elastic protrusion 109 that supports the switch board 107. As a result, the switch unit 107 may be out of the mounting portion, or the connection metal foil connected to the switch 105 may be cut, causing problems or damage to the switch unit.
特開２０１２－７８０８６号公報JP 2012-78086 A
　本発明は、上記従来の課題を解決するもので、スイッチの操作性を維持しつつ、スイッチ部の不具合や破損を防止するものである。 The present invention solves the above-described conventional problems, and prevents malfunction and breakage of the switch portion while maintaining the operability of the switch.
　上記従来の課題を解決するために、本発明の冷蔵庫は、貯蔵室と、貯蔵室の前方開口を開閉可能に覆う扉と、扉の前面に設けられた凹部と、凹部内に設置され前面にスイッチが設けられたスイッチ基板と、スイッチ基板の前面を覆うカバーと、スイッチ基板の後方に設けられた第１の支持部および第２の支持部を備える。 In order to solve the above-described conventional problems, a refrigerator according to the present invention includes a storage room, a door that covers the front opening of the storage room so as to be openable and closable, a recess provided on the front surface of the door, and a front surface that is installed in the recess. A switch board provided with a switch, a cover covering the front surface of the switch board, and a first support part and a second support part provided behind the switch board are provided.
　第１の支持部は、弾力性を有してスイッチ基板を弾性的に支持する。第２の支持部は、スイッチ基板との間に空間を有し、第１の支持部より硬いものである。 The first support portion has elasticity and elastically supports the switch board. The second support part has a space between it and the switch substrate, and is harder than the first support part.
　本発明の冷蔵庫によれば、第１の支持部によって、スイッチ基板を後方から弾性的に支持することにより、スイッチとカバーとの間隔を適切に保持して良好な操作性をもたらすことができる。 According to the refrigerator of the present invention, the switch substrate is elastically supported from the rear by the first support portion, so that the distance between the switch and the cover can be appropriately maintained and good operability can be provided.
　前方から押圧されてスイッチ基板が第１の支持部とともに後退すると、スイッチ基板は、第２の支持部に当接するため、それ以上後退することがない。このようにして、スイッチ基板が取り付け部から外れたり、スイッチに接続される結線用の金属箔が切断されたりすることを防止できる。このようにして、信頼性の高い冷蔵庫を実現することができる。 When the switch board is retreated together with the first support part by being pressed from the front, the switch board contacts the second support part, and therefore does not retreat any further. In this way, it is possible to prevent the switch board from being detached from the mounting portion and the metal foil for connection connected to the switch from being cut. In this way, a highly reliable refrigerator can be realized.

　本発明に係る第１の態様の冷蔵庫は、貯蔵室と、貯蔵室の前方開口を開閉可能に覆う扉と、扉の前面に設けられた凹部と、凹部内に設置され前面にスイッチが設けられたスイッチ基板と、スイッチ基板の前面を覆うカバーと、スイッチ基板の後方に設けられた第１の支持部および第２の支持部を備える。 The refrigerator according to the first aspect of the present invention includes a storage chamber, a door that covers the front opening of the storage chamber so as to be openable and closable, a recess provided in the front surface of the door, and a switch provided in the front surface that is installed in the recess. A switch board, a cover that covers the front surface of the switch board, and a first support part and a second support part that are provided behind the switch board.
　第１の支持部は、スイッチ基板を弾性的に支持する。第２の支持部は、スイッチ基板との間に空間を有し、第１の支持部より硬いものである。 The first support part elastically supports the switch board. The second support part has a space between it and the switch substrate, and is harder than the first support part.
　本態様によれば、第１の支持部によって、スイッチ基板を後方から弾性的に支持するため、スイッチとカバーとを密着させることができる。 According to this aspect, since the switch substrate is elastically supported from the rear by the first support portion, the switch and the cover can be brought into close contact with each other.

As a result, particularly when an electrostatic switch is used, good operability and durability against pressing can be realized.
　本発明の第４の態様の冷蔵庫は、第１～第３のいずれか一つの態様において、第１の支持部が、先端が湾曲することで弾力性を備えたものである。 In the refrigerator according to the fourth aspect of the present invention, in any one of the first to third aspects, the first support portion has elasticity because the tip is curved.

　図１は、本発明の実施の形態に係る冷蔵庫の外観を示す正面図である。 FIG. 1 is a front view showing an appearance of a refrigerator according to an embodiment of the present invention.

　冷蔵室３は、複数の収納棚１４が着脱自在に設けられて、複数に仕切られた空間を内部に有している。扉７、８は、冷蔵庫本体１と同様の構成によって断熱性を有する。 The refrigerator compartment 3 has a plurality of storage shelves 14 detachably provided and has a plurality of partitioned spaces inside. The doors 7 and 8 have heat insulation properties by the same configuration as the refrigerator main body 1.
　冷凍室２の背面に設けられた冷却室１０には、冷却器１０ａと送風ファン１１とが設けられている。冷却室１０で生成された冷気は、ダクト１３を介して冷凍室２と冷蔵室３とに供給される。冷蔵庫本体１の背面下方には、圧縮機１２が設けられている。 A cooler 10 a and a blower fan 11 are provided in the cooling chamber 10 provided on the back surface of the freezer compartment 2. The cold air generated in the cooling chamber 10 is supplied to the freezer compartment 2 and the refrigerator compartment 3 through the duct 13.

　以下、簡単のため、図３～図６において、図面上における右方向、左方向を、それぞれ前方、後方と呼ぶこととする。それに伴い、断面における右側の面を前面と呼び、断面における左側の面を後面と呼ぶこととする。 Hereinafter, for the sake of simplicity, in FIGS. 3 to 6, the right direction and the left direction on the drawings are referred to as the front and rear, respectively. Accordingly, the right surface in the cross section is referred to as the front surface, and the left surface in the cross section is referred to as the rear surface.
　図３、４に示されるように、凹部１５は、扉７の前面に形成される。凹部１５には、樹脂製で矩形状凹状の基板ケース１６が設置される。基板ケース１６の周囲には発泡断熱材６が充填される。 3 and 4, the recess 15 is formed on the front surface of the door 7. The concave portion 15 is provided with a resin-made rectangular concave substrate case 16. A foam insulation 6 is filled around the substrate case 16.
　スイッチ基板１７は、基板ケース１６の内側に設置され、その前面に、スイッチ１８と表示手段（図示せず）とを備える。スイッチ１８は、冷凍室２や冷蔵室３の温度等を設定するため静電スイッチである。表示手段は、ＬＥＤ等で構成される。 The switch board 17 is installed inside the board case 16, and includes a switch 18 and display means (not shown) on the front surface thereof. The switch 18 is an electrostatic switch for setting the temperature of the freezer compartment 2 and the refrigerator compartment 3. The display means is constituted by an LED or the like.
　カバー２０は、弾性変形可能な合成樹脂板で構成され、凹部１５とスイッチ基板１７とを覆う。カバー２０は、その外周の適所に設けられた爪片２０ａが扉７の金属製の表面板７ｂに嵌合し、扉７に取り付けられる。カバー２０は、その周辺近傍に扉７の内側に突出する筒状壁２１を備える。 The cover 20 is made of an elastically deformable synthetic resin plate and covers the recess 15 and the switch substrate 17. The cover 20 is attached to the door 7 by engaging claw pieces 20 a provided at appropriate positions on the outer periphery of the cover 20 with the metal surface plate 7 b of the door 7. The cover 20 includes a cylindrical wall 21 that protrudes inside the door 7 in the vicinity of the periphery thereof.
　スイッチ基板１７は、筒状壁２１から筒状壁２１の内側に突出するいくつかの係止突起２２と、カバー２０の前板２０ｂとの間に嵌合する。カバー２０のスイッチ１８と対向する内側（後面）には印刷等が施されて、操作スイッチ部２３が構成される。 The switch board 17 is fitted between several locking projections 22 protruding from the cylindrical wall 21 to the inside of the cylindrical wall 21 and the front plate 20 b of the cover 20. Printing or the like is performed on the inner side (rear surface) of the cover 20 facing the switch 18, and the operation switch unit 23 is configured.
　基板ケース１６の内側底面、すなわち、基板ケース１６内のスイッチ基板１７に対向する側の面に、第１の支持部２４および第２の支持部２５が、スイッチ基板１７に向けて突出するように、基板ケース１６と一体的に形成される。 The first support portion 24 and the second support portion 25 protrude toward the switch substrate 17 on the inner bottom surface of the substrate case 16, that is, the surface of the substrate case 16 facing the switch substrate 17. , Formed integrally with the substrate case 16.
　第１の支持部２４および第２の支持部２５も、基板ケース１６と同じく樹脂製である。第１の支持部２４は、先端がフック状に湾曲する形状のため、前後方向（図４では横方向）に弾力性を有する。一方、第２の支持部２５は、直線的形状のため剛性を有する。 The first support portion 24 and the second support portion 25 are also made of resin, like the substrate case 16. Since the first support portion 24 has a shape whose tip is curved like a hook, it has elasticity in the front-rear direction (lateral direction in FIG. 4). On the other hand, the second support portion 25 has rigidity because of its linear shape.
　第１の支持部２４は、常にスイッチ基板１７に接触し、操作スイッチ部２３の前面側から圧力が加わると後方に若干撓む。 The first support portion 24 is always in contact with the switch substrate 17 and slightly bends backward when pressure is applied from the front side of the operation switch portion 23.
　第２の支持部２５は、スイッチ基板１７の適所に分散配置される。第１の支持部２４が前面からの圧力により後ろに撓むと、第２の支持部２５の先端がスイッチ基板１７に当接するよう、第２の支持部２５は、第１の支持部２４より０．３ｍｍ～０．５ｍｍほど短い。 The second support portions 25 are distributed and arranged at appropriate positions on the switch board 17. When the first support portion 24 bends backward due to pressure from the front surface, the second support portion 25 is less than the first support portion 24 so that the tip of the second support portion 25 contacts the switch substrate 17. It is as short as 3mm to 0.5mm.
　第１の支持部２４が撓んで、スイッチ基板１７が第２の支持部２５に当接すると、第２の支持部２５によって、スイッチ基板１７は、それ以上、押し込まれることがない。 When the first support portion 24 is bent and the switch substrate 17 comes into contact with the second support portion 25, the switch substrate 17 is not pushed further by the second support portion 25.
　このように、第２の支持部２５が、基板ケース１６とスイッチ基板１７との間隔を一定距離以上に保つスペーサとして機能することで、スイッチ基板１７が取り付け部から外れたり、スイッチに接続される結線用の金属箔が切断されたりという、スイッチ基板１７の不具合や破損を防止することができる。 As described above, the second support portion 25 functions as a spacer that keeps the distance between the substrate case 16 and the switch substrate 17 at a certain distance or more, so that the switch substrate 17 is detached from the attachment portion or connected to the switch. It is possible to prevent the trouble or breakage of the switch substrate 17 that the metal foil for connection is cut.
　なお、本実施の形態では、第２の支持部２５は、直線的形状により剛性を有するものとしたが、必ずしも完全な剛性は必要ない。 In the present embodiment, the second support portion 25 has rigidity due to a linear shape, but it is not always necessary to have complete rigidity.
　要するに、スイッチ基板１７が前方から押圧されて第１の支持部２４とともに後退した場合でも、第１の支持部２４より硬い第２の支持部２５によって、スイッチ基板１７が、許容範囲を超えて撓まなければ十分である。 In short, even when the switch board 17 is pressed from the front and retracted together with the first support part 24, the switch board 17 is bent beyond the allowable range by the second support part 25 that is harder than the first support part 24. If not, it is enough.
　また同時に、上記構成により、以下の効果が得られる。 At the same time, the above-described configuration provides the following effects.
　スイッチ基板１７は、第１の支持部２４によって弾性的に支持され、常にカバー２０に押圧されている。そのため、スイッチ１８の感度が損なわれず、良好なスイッチ性能が得られる。 The switch board 17 is elastically supported by the first support portion 24 and is always pressed against the cover 20. Therefore, the sensitivity of the switch 18 is not impaired and good switch performance can be obtained.
　スイッチ１８を覆うカバー２０も、第１の支持部２４と同様に弾性変形可能であるため、スイッチ１８が操作されると、操作スイッチ部２３が若干撓むため、ユーザにあたかもメンブレンスイッチを操作するような感触を与えることができる。このようにして、操作性が向上する。 Since the cover 20 covering the switch 18 can be elastically deformed similarly to the first support portion 24, the operation switch portion 23 is slightly bent when the switch 18 is operated, so that the user operates the membrane switch. Such a feeling can be given. In this way, operability is improved.
　さらに、第１の支持部２４は、操作スイッチ部２３に対応する位置に配置されるので、静電スイッチであるスイッチ１８をカバー２０に容易に密着させることができ、より良好な操作性を実現することができる。 Furthermore, since the first support portion 24 is disposed at a position corresponding to the operation switch portion 23, the switch 18 that is an electrostatic switch can be easily brought into close contact with the cover 20, thereby realizing better operability. can do.
　本実施の形態では、発泡断熱材６が充填され断熱性を有する扉７において、発泡断熱材６に形成された凹部１５に、凹状箱型の基板ケース１６が埋設されている。第１の支持部２４および第２の支持部２５は、基板ケース１６の内側に設けられてスイッチ基板１７を支持するよう構成されている。 In the present embodiment, a concave box-shaped substrate case 16 is embedded in a recess 15 formed in the foam heat insulating material 6 in the door 7 filled with the heat insulating material 6 and having heat insulation. The first support portion 24 and the second support portion 25 are provided inside the substrate case 16 and configured to support the switch substrate 17.
　この構成により、扉の製造時に、基板ケース１６を取り付けるための冶具が、第２の支持部２５を介して基板ケース１６を押圧するため、発泡断熱材６の発泡のばらつきにより基板ケース１６の裏側に生じた凸凹を平坦にすることができる。 With this configuration, since the jig for attaching the substrate case 16 presses the substrate case 16 via the second support portion 25 when manufacturing the door, the back side of the substrate case 16 is caused by the variation in foaming of the foam heat insulating material 6. It is possible to make the unevenness generated in the flat.
　このように、スイッチ１８とカバー２０との接触、および、スイッチ基板１７の変形許容量の精度を統制することにより、スイッチ１８に静電スイッチを用いた場合の良好な操作性と押圧に対する耐久性とを実現することができる。 In this way, by controlling the contact between the switch 18 and the cover 20 and the accuracy of the deformation allowable amount of the switch substrate 17, good operability and durability against pressing when the switch 18 is used as an electrostatic switch. And can be realized.
　第１の支持部２４および第２の支持部２５は、寸法と形状とは異なるが、金型を用いて基板ケース１６と同時に形成することができる。そのため、第１の支持部２４と第２の支持部２５とは、簡単かつ安価に製造することができる。 The first support portion 24 and the second support portion 25 are different in size and shape, but can be formed simultaneously with the substrate case 16 using a mold. Therefore, the 1st support part 24 and the 2nd support part 25 can be manufactured simply and cheaply.
　また、先端が湾曲した形状の第１の支持部２４を、基板ケース１６上に形成するだけなので、ゴムなどの弾性部材を別途用いる必要がない。このように、部品点数の削減によりコストダウンが図れる。 Further, since the first support portion 24 having a curved tip is only formed on the substrate case 16, it is not necessary to separately use an elastic member such as rubber. Thus, the cost can be reduced by reducing the number of parts.
　さらに、第１の支持部２４と第２の支持部２５とは、基板ケース１６に一体形成されるので、これらを別部品で構成した場合の部品間の寸法ばらつきを低減して、精度よく形成することができる。これによって、カバー２０とスイッチ１８との接触とスイッチ基板１７の変形許容量とを容易かつ確実に統制することができ、製品の信頼性を担保することができる。 Further, since the first support portion 24 and the second support portion 25 are formed integrally with the substrate case 16, they are formed with high accuracy by reducing the dimensional variation between the components when they are configured as separate components. can do. Thereby, the contact between the cover 20 and the switch 18 and the deformation allowable amount of the switch substrate 17 can be easily and reliably controlled, and the reliability of the product can be ensured.
　以上のように、本実施の形態によれば、スイッチの良好な操作性とスイッチ基板の押圧に対する耐久性とを両立させた冷蔵庫を提供することができる。 As described above, according to the present embodiment, it is possible to provide a refrigerator that achieves both good operability of the switch and durability against pressing of the switch board.
　言うまでもなく、本実施の形態は本発明を実施するための一例であり、本発明の目的が達成できる限り、多少の修正と変更は可能である。 Needless to say, this embodiment is an example for carrying out the present invention, and some modifications and changes are possible as long as the object of the present invention can be achieved.
　例えば、スイッチ１８として必ずしも静電スイッチを用いる必要はなく、クリック感のある他の形式のスイッチでも良い。このようなスイッチを用いる場合、静電スイッチに比べてカバーとスイッチの間の距離に関する精度を必要としない。しかし、このような形態も、クリック感を維持しつつ、スイッチ基板の不具合や破損を防止できるという点で、本発明の一実施の形態となり得る。 For example, it is not always necessary to use an electrostatic switch as the switch 18, and another type of switch with a click feeling may be used. When such a switch is used, the accuracy regarding the distance between a cover and a switch is not required compared with an electrostatic switch. However, such a configuration can also be an embodiment of the present invention in that a click feeling can be maintained and a malfunction or breakage of the switch substrate can be prevented.
　本実施の形態では、第１の支持部２４は、先端がフック状に湾曲する形状を有する。しかし、第１の支持部２４と同様の弾力性を有する形状であれば適用可能である。 In the present embodiment, the first support portion 24 has a shape whose tip is curved like a hook. However, any shape having elasticity similar to that of the first support portion 24 is applicable.
　以上詳細に説明したように、本発明によれば、スイッチとカバーとの接触を確実に保持して良好な操作性を実現するとともに、スイッチが強く押圧されてもスイッチ基板の不具合や破損を防止することができる。従って、本発明は、一般消費者用はもちろん、業務用の冷蔵庫などの他の用途にも適用できる。 As described above in detail, according to the present invention, the contact between the switch and the cover is reliably maintained to achieve good operability, and even if the switch is strongly pressed, the malfunction or breakage of the switch board is prevented. can do. Therefore, the present invention can be applied not only to general consumers but also to other uses such as a commercial refrigerator.
