Abstract

PROBLEM TO BE SOLVED: To dispose an operating board near a door outer plate, to limit an area for reducing an inside depth of the door of a board containing case to an inside and a thickness of a heat insulator to a necessary minimum limit and to improve reliability by disposing a board side connector on a surface of the board to an opposite side to a pushbutton or the like disposed on the board. SOLUTION: A board side connector 17 is provided at an intermediate part of an operating board 14 in a vertical direction, and lead pins of the connector 17 are electrically connected to a circuit of a pattern surface of the board 14 through the pattern surface. The connector 17 is connected to a lead wire side connector 11 of a door side connected to a control board of a refrigerator body through a punched hole of an outer plate 1a of a door to contain the board. Accordingly, an insulation surface can be mounted directly on the surface of the outer plate of the door. A hole provided at a door plate made of an iron plate can be relatively reduced as compared with a size of the board to reduce an area for generating a rust and to prevent a distortion of the door plate made of the iron plate due to an insufficient strength when a heat insulator is foamed.

【発明の属する技術分野】
本発明は冷蔵庫等の扉面に運転制御等の操作パネルを取り付けた構造に関するものである。
【０００２】
【従来の技術】
従来の冷蔵庫には、内側に形成された複数の貯蔵室の温度の調節を使用者を行うための操作ボタン等を有する操作パネルを、冷蔵庫扉面に装着させたものがある。このような従来技術の一例は実開昭６２−５５０８６号公報に開示されている。
【０００３】
この従来技術においては、冷蔵室扉は鋼板製の扉外板やその上下部に各々被せられる樹脂製のエンドピースを備え、前記冷蔵室扉内にウレタンフォーム等の断熱材を充填して構成されている。冷蔵室扉の右上方部位には鉄板製扉外板の開口部が形成され、この開口部内に各室の温度調節用の化粧カバーが配設されている。この化粧カバーは前面を向く複数個の操作押しボタン等が、また化粧カバーの裏側には操作基板が配置され、この操作基板の回路パターン面の扉内側には冷蔵庫の制御基板と操作基板とをつなぐコネクタやスイッチ及びリード線等が配設されている。
【０００４】
更にこの操作基板の扉内側にはこれらの操作基板と冷蔵室扉内との断熱材の接触を防ぐための樹脂製の基板収納ケースが設けられている。
【０００５】
【発明が解決しようとする課題】
このような従来の技術においては、次のような問題があった。
即ち、上記基板収納ケースの扉厚さ方向の高さ分だけ、扉の内側の断熱材の厚さが小さくなってしまう。このため、この部分での扉の断熱性能は低減し熱漏洩が大きくなってしまい、電力消費料が大きくなってしまうという問題については、考慮されていなかった。
【０００６】
また、基板収納ケース３６が断熱材側が深くなっていると扉外板と扉内板間に発泡断熱材を充填する時、基板収納ケースが障害となり先の発泡断熱材の充填が不十分となり、扉の表面に皺や歪み等の不良が生じやすくなり、生産コストを上昇させてしまうという問題については考慮されていなかった。
【０００７】
さらには、上記操作基板の扉内側の扉外側（パネル側）の面には、スイッチやリード線を接続するための回路パターンが形成されているが、上記操作パネルの化粧板上のボタンと基板側のスイッチとを接続するための連結棒が必要となり、部品数が増加してコストの上昇を招いてしまう点については考慮されていなかった。
【０００８】
もし、この問題点を解決すべく、ケースを無くして、基板を扉外板よりも扉外側に設けた場合には、操作パネルの扉外板側先端の扉外板表面からの突出高さが大きくなり、冷蔵庫意匠を低減させるのみならず、扉の開閉時に冷蔵庫周囲の壁、家具や調度品と扉とが衝突した場合に、先に操作パネルが衝突することになり、パネルが損傷しやすくなり、冷蔵庫の信頼性を低下させることになる。
【０００９】
また、操作基板の扉内側面にパターンが形成されているため、基板を扉の外板側に取付ける場合には、基板を絶縁する必要から基板の大きさより大きな開口を扉外板に形成する必要があった。このため、扉外板の上記開口の周縁部が錆び易くなり、この点でも冷蔵庫の信頼性を低下させてしまう点については考慮されていなかった。
【００１０】
また、上記の開口の面積が大きく、基板の収納ケースも大きくなり、ケースに対向する部分の断熱材充填時に該発泡断熱材の影響を受け、扉外板が歪む等の問題が生じてしまい、生産コストを上昇させてしまうという点については考慮されていなかった。
【００１１】
さらに基板の収納部容積が大きくなると先に述べたこの操作基板の投影面の扉断熱材の厚さ寸法が小さくなりこれが庫外からの熱漏洩を増加させる一因にもなっていた。従って冷蔵庫の省電力の面からも好ましくないものであった。
【００１２】
本発明の目的は、信頼性の高い冷蔵庫を提供することにある。
【００１３】
【課題を解決するための手段】
上記目的を達成するために、本発明の冷蔵庫は、冷蔵庫本体の上部に配設される冷蔵室と、内板と鋼板製の外板とこれらの間に配置された断熱材とを有し前記冷蔵室を開閉する扉と、前記扉の外板上に設けられた縦ハンドルと、前記外板上に設けられ使用者が操作可能な操作手段とを備えた冷蔵庫において、
前記操作手段は、前記外板上に形成された開口部の前記冷蔵庫前方側に配置され前記開口を覆う基板と、前記基板の前記冷蔵庫前方側の面上に設けられた電気品と、前記電気品に通電するコネクタ部と前記コネクタ部から延出するリード線とを備え、前記縦ハンドルの上方に連接し、前記縦ハンドルの頂部よりも前記外板表面から低く突出しており、
前記基板の前記冷蔵庫後方側の面は前記外板に対向し、前記コネクタ部は前記基板の前記冷蔵庫後方側の面上に配置され、前記リード線は前記基板から前記開口部へと延出しており、かつ、前記基板と前記扉の外側との間は絶縁されており、
前記基板は化粧カバーによって覆われ、この化粧カバーを前記縦ハンドルに連接して設けると共に化粧カバーには操作部が設けられ、この操作部は前記基板に配置したスイッチに対応しており、
前記断熱材に埋設され、かつ前記基板よりも小さな樹脂製の基板収納ケースによって、前記リード線が保護されることを特徴とするものである。
【００１４】
さらに、前記基板と前記外板との間に空間を備えたものである。または、前記基板と前記扉の外側との間にこれらを絶縁する部材を備えたものである。
【００１５】
【発明の実施の形態】
以下本発明の一実施例を図面により説明する。図１〜図７を参照しながら説明する。先ず、図１は本実施例の全体構成で扉除去状態を示す正面図、図２は本実施例の全体構成を示している冷蔵庫の縦断面図である。図１、２に於いて１０は冷蔵庫本体で、外箱と内箱及びその空間内にウレタンフォーム等の断熱材で構成されこれら本体内には冷凍サイクルや各室に冷気を供給する機構などが組み込まれている。また、冷蔵庫本体１０内には上から順に冷蔵室２、チルドルーム３、野菜室５、冷凍室７、９が各々設けられている。
【００１６】
また、前記冷蔵室２の前面部には後述する冷蔵室扉１がヒンジ(図示せず）を介して開閉となるように設けられている。前記野菜室５及び冷凍室７、９の扉は引き出し式となっており、上から野菜室扉４、冷凍室扉６、８の順に引き出し可能に設置され、さらに前記各扉には食品を収納する冷蔵室貯蔵容器や冷凍室貯蔵容器がそれぞれ連結されている。
【００１７】
図３は本実施例の操作パネル部の要部縦断面図、図４は前記冷蔵室扉の操作パネル部を正面から見た要部正面図である。冷蔵室扉１は正面側には薄板鉄板の扉外板１ａで庫内側には扉内板２１が、上下には扉外板１ａに嵌合する樹脂製の扉カバー（図示せず）でそれぞれ組み込まれ、その内部にはウレタンフォーム等の断熱材を充填して構成されている。また、前記扉内板２１の庫内側にはドアポケットが複数個上下方向に設けられている。更に図４に示すように冷蔵室扉１の左辺部寄りに扉外板１ａ面上にハンドル１９が、前記ハンドル１９の上部は連接して操作パネル１５を配設させている。この操作パネル１５の扉外板１ａの表面からの突出した高さは、前記ハンドル１９の扉外板１ａの表面から突出した高さが最も大きな部分、すなわちハンドルの頂部よりも低くなるように形成されている。
【００１８】
以下、この操作パネル１５について図５〜図６により述べると、図５は図３の操作パネル１５の要部組立分解図、図６は操作パネル１５の要部拡大断面図である。前記操作パネル１５周辺の部品構成については図５に示すごとく操作基板１４はパターン面１３側に操作用押しボタン１２、スイッチ等の表面実装部品及び接続用ハンダ等を有している。またこの操作基板１４を扉外板面１ａに取り付けるために前記基板のパターン面１３より基板取付カバー２０を包み込むように該基板取付カバー２０の内側に狭持リブ等で固定する構造となっており、また前記操作基板１４と扉外板１ａとの間に隙間を設けるようにした。尚、この基板取付カバー２０は操作基板１４のパターン面１３を覆う関係で材質は樹脂等の絶縁材を使用することが望ましい。また、前記説明した化粧カバー２２は扉外板表面１ａにネジ等により取付けた基板取付カバー２０を覆うように装着する構成となっている。尚、前記装着は前記基板取付カバー２０と該化粧カバー２２の引っ掛け爪の嵌合する関係にすることが望ましい。ここで前記化粧カバー２２は図３、４に示す如く扉外板面１ａに取り付けた縦ハンドル１９の真上に連接した関係で外観意匠的に良い配設となっている。
【００１９】
また、前記操作基板１４のパターン面１３を覆う化粧カバー２２の構成について述べると、該化粧カバー２２には急冷凍や急冷却等の押しボタン１２を設け、先の操作基板１４のパターン面１３に設けたスイッチに各々対応させる構成を成し、化粧カバー２２に設けた押しボタン１２を押すことにより前記スイッチを入り切りさせることで顧客の要望に対応出来る制御とすることが出来る。
【００２０】
更に、先の基板パターン面１３裏側の絶縁面について述べると、該操作基板１４の上下方向の中間部には基板側コネクタ１７が設けられ、前記基板側コネクタ１７のリードピンは操作基板１４のパターン面１３に貫通されパターン面１３の回路に電気的に接続されている。また前記基板側コネクタ１７は後述する扉外板１ａの基板を収納させるための抜き穴により前記冷蔵庫本体１０の制御基板へ接続される扉側のリード線側コネクタ１１とつながるようになっている。
【００２１】
次に化粧カバー２２及び操作基板１４とその基板取付カバー２０の扉外板１ａへの取付構成について説明する。先ず、扉外板１ａの左寄りの前記ハンドル１９の上方に位置する所に前記操作基板１４のパターン面裏側の絶縁面に設けた基板側コネクタ１７及びリード線側コネクタ１１のリード線を収納出来る大きさの穴を開口し、該開口穴には該扉外板１ａ内の断熱材側に前記基板側コネクタ１７、リード線及び操作基板１４等を保護する基板収納ケース１６を設けるように構成する。
【００２２】
また、この基板収納ケース１６の上方より基板収納ケース１６内の前記基板側と接続するためのリード線側コネクタ１１を延出している。このリード線側コネクタ１１は冷蔵庫本体１０からの冷蔵室扉１の上部ヒンジ部（図示せず）を経由して電気的に接続されており、前記化粧カバー２２に設けられた押しボタン１２を顧客が操作することにより前記冷蔵庫の各室を好みに応じて制御出来るようになっている。尚、前記基板収納ケース１６についてはリード線等を収納する関係上、樹脂製にすることが望ましい。
【００２３】
また、本実施例での操作基板１４のパターン面１３はスイッチ等の実装部品を有し、パターン面１３の裏側の絶縁面はほぼ中間部分に基板側コネクタ１７のみ配設させている。
【００２４】
従って前記絶縁面を直接扉外板面１ａに取り付けることも可能であるが、扉外板面１ａへの水分結露等で操作基板１４に水分が付着することも考えられ、また鉄製扉外板１ａ表面からの絶縁性を確保する関係から扉外板１ａ表面と操作基板１４のパターン面１３の裏側の絶縁面との間に隙間を設けるようにした。尚、この隙間は１〜２ｍｍ程度であり、この隙間寸法は前述の如く基板取付カバー２０に設けた操作基板１４固定用リブにより確保出来る構成となっている。
【００２５】
また、断熱材中に埋設される前記基板収納ケース１６の大きさをコネクタ基板側コネクタ１７と結線用リード線及びリード線側コネクタ１１が入る大きさ（基板の大きさの１／２以下）とすることにより、鉄板製扉外板１ａに設ける穴もこれに伴い小さく出来るので従来この種の扉で問題になっていた扉外板１ａの錆対策或いは扉外板１ａが部分的に劣化し、断熱発泡時に扉外板１ａが歪むということを最小限にすることが出来るものである。
【００２６】
すなわち、本実施の例においては、基板側コネクタ１７は前記基板１４上に配置された押しボタン１２やスイッチとは反対の側の面に配置されており、本実施の例ではパターン面１３は押しボタン１２やスイッチの側に形成されている。
【００２７】
このような構成により、従来のごとく操作基板１４全体を収納するケースを扉の内側の断熱材中埋設する必要が無く、操作基板を扉外板近傍に配置でき、基板収納ケースの扉の内側への奥行き深さや、断熱材の厚みが小さくなる領域を必要最小限のものとすることができる。
【００２８】
このため、扉断熱材中に設けた基板収納ケースの大きさが小さくなり扉外板と扉内板間に発泡断熱材を充填したとき、発泡断熱材が扉の内側に行き渡り、充填の不良による不良品の発生が低減され、冷蔵庫の製造コストが低減されると同時に、信頼性も向上する。。更に、基板収納ケースを小型化することにより扉断熱材の厚さを十分確保する事が出来、庫外からの熱漏洩量が減少し冷蔵庫の省電力効果も期待できる。
【００２９】
上記コネクタと押しボタン１２やスイッチとが同一の基板上の面にあり、反対側にパターン面が形成されている場合には、パターン面の絶縁の必要から樹脂製等の絶縁性のあるケースにより基板を覆う必要があり、かつケースと基板のパターン面とは所定の隙間を要することになる。さらに、上記した通り、コネクタやボタン類を扉表面上に突出させると信頼性を損ない易いという問題から、ケースごと扉内側の断熱材中に埋設する必要がある。このため、基板収納ケース１６が配置された扉の断熱材の厚さは大きく低減されてしまうことになるのである。
【００３０】
次に上記操作基板１４と扉外板１ａとの絶縁性をさらに向上させた実施例について説明する。鉄製扉外板面１ａと操作基板１４のパターン面の裏側の絶縁面との絶縁性を高くするためには前記操作基板１４のパターン面１３の裏側に予め絶縁材を設ける構造が最も良い方法である。図７に絶縁材を設けた実施例を示す。本実施例では絶縁材としてポリエチレンテレフタレート製の絶縁シート２３を扉外板１ａ表面と操作キバン１４のパターン面１３の裏側の絶縁面との間に挿入することにより鉄製扉外板１ａ表面からの絶縁性を確保したものである。
【００３１】
以上の説明で明らかなように本実施の例によれば次のような効果を有する。
【００３２】
即ち基板はパターン面に表面実装部品を実装し、パターン面裏側の絶縁面に基板側コネクタを設け前記基板側コネクタ１７のリード線がパターン面側に基板を貫通させると共に、該パターン面が扉表面に取り付けられる化粧カバー側に位置し、該基板側コネクタが収納ケース内に位置するように構成したので、化粧カバーの厚みを薄くすることが出来る。
【００３３】
また鉄板製扉板に設ける穴を基板の大きさに比較して小さく出来ることにより、錆の発生する面積が低減され、扉板の錆対策が容易になることは勿論、断熱材発泡時強度不足等の為鉄板製扉板が歪むのを防止出来るものである。
【００３４】
また、従来操作パネル側に設けていた押しボタンとスイッチ間をつなぐ連結棒を不要とすることが出来、部品点数の削減と原価低減につながるものである。また、この操作パネル１５の扉外板１ａの表面からの突出した高さは、前記ハンドル１９の扉外板１ａの表面から突出した高さが最も大きな部分、すなわちハンドルの頂部よりも低くなるように形成されているので、扉の開閉時等に扉が冷蔵庫周囲の壁や家具、調度品と衝突する際に最初に衝突する部分をハンドル部とすることでパネルの損傷を防止して冷蔵庫の信頼性を高くすることができる。
【００３５】
更に、基板収納ケースを小型化することにより扉断熱材の厚さを十分確保する事が出来、庫外からの熱漏洩量が減少し冷蔵庫の省電力効果も期待できる。
【００３６】
また、扉板面より外方に配設された基板のハンダ面を化粧カバーで覆うようにしたことで、扉板面へ組立構成が簡単となることで扉板面への組立工程も大幅に短縮することが出来る。
【００３７】
さらに基板のパターン面を覆う化粧カバーをハンドルに連接して設けると共に、この化粧カバーに急冷却、急冷凍等の押しボタンを設け該押しボタンは基板に配置したスイッチに対応させ、化粧カバーに設けた押しボタンを押すことにより該スイッチを入り切りさせるようにしたので、前記ハンドルの真上に連接した操作押しボタンにより顧客の操作が行い易くなり、また意匠的に良くなるものである。
【００３８】
また、基板のパターン面の裏側と扉外板表面との間に隙間を設けるようにしたので基板と扉外板表面との絶縁性能も向上し、また扉外板表面に付着した水が基板に接触することを防止出来、信頼性の高い冷蔵庫を提供出来る。
【００３９】
さらに基板のパターン面の裏面と扉外板間に絶縁部材を追加することにより、さらなる絶縁性能の向上を図ることが出来る。
【００４０】
【発明の効果】
以上の通り、本発明によれば、信頼性の高い冷蔵庫を提供できる。

BACKGROUND OF THE INVENTION
The present invention relates to a structure in which an operation panel for operation control or the like is attached to a door surface of a refrigerator or the like.
[0002]
[Prior art]
In some conventional refrigerators, an operation panel having operation buttons and the like for adjusting the temperature of a plurality of storage chambers formed on the inside is attached to the refrigerator door surface. An example of such a prior art is disclosed in Japanese Utility Model Laid-Open No. 62-55086.
[0003]
In this prior art, the refrigerator compartment door is composed of a steel door outer plate and resin end pieces that are respectively put on the upper and lower portions thereof, and the refrigerator compartment door is filled with a heat insulating material such as urethane foam. ing. An opening of an iron plate door outer plate is formed in the upper right part of the refrigerator compartment door, and a decorative cover for adjusting the temperature of each chamber is disposed in the opening. This decorative cover has a plurality of operation push buttons facing the front, an operation board is arranged on the back side of the decorative cover, and the control board and the operation board of the refrigerator are placed inside the circuit pattern surface of the operation board. A connector, a switch, a lead wire, and the like to be connected are provided.
[0004]
Further, a resin-made substrate storage case is provided on the inside of the operation board door to prevent the heat insulation material from contacting the operation board and the inside of the refrigerator compartment door.
[0005]
[Problems to be solved by the invention]
Such a conventional technique has the following problems.
That is, the thickness of the heat insulating material inside the door is reduced by the height of the substrate storage case in the door thickness direction. For this reason, the problem that the heat insulation performance of the door in this portion is reduced, the heat leakage is increased, and the power consumption is increased is not taken into consideration.
[0006]
In addition, when the board storage case 36 is deep on the heat insulating material side, when filling the foam heat insulating material between the door outer plate and the door inner plate, the board storage case becomes an obstacle and the previous foam heat insulating material is insufficiently filled, The problem that defects such as wrinkles and distortion tend to occur on the surface of the door and increase the production cost has not been considered.
[0007]
Furthermore, a circuit pattern for connecting a switch or a lead wire is formed on the door outside (panel side) inside the door of the operation board. A connecting rod for connecting to the switch on the side is required, and the point that the number of parts increases and the cost increases is not taken into consideration.
[0008]
In order to solve this problem, when the case is removed and the board is provided outside the door outer plate, the height of the protrusion from the door outer plate surface at the front end of the door outer plate of the operation panel is Not only does it increase the size of the refrigerator design, but also when the door collides with the wall, furniture or furniture around the refrigerator when the door is opened and closed, the operation panel will collide first, and the panel is easily damaged. This will reduce the reliability of the refrigerator.
[0009]
In addition, since the pattern is formed on the inner surface of the door of the operation board, when installing the board on the outer plate side of the door, it is necessary to form an opening larger than the size of the board on the door outer plate because it is necessary to insulate the board. was there. For this reason, the peripheral part of the said opening of a door outer plate becomes easy to rust, and the point which reduces the reliability of a refrigerator also in this point was not considered.
[0010]
In addition, the area of the opening is large, the storage case of the substrate is also large, and when the heat insulating material is filled in the portion facing the case, it is affected by the foam heat insulating material, causing problems such as distortion of the door outer plate, The point of increasing production costs was not considered.
[0011]
Further, when the capacity of the substrate storage portion is increased, the thickness dimension of the door heat insulating material on the projection surface of the operation substrate described above is reduced, which is one factor for increasing heat leakage from the outside of the cabinet. Therefore, it was not preferable from the viewpoint of power saving of the refrigerator.
[0012]
An object of the present invention is to provide a highly reliable refrigerator.
[0013]

The board-side connector 17 is connected to the door-side lead wire-side connector 11 connected to the control board of the refrigerator main body 10 through a hole for accommodating the board of the door outer plate 1a described later.
[0021]
Next, the attachment structure of the decorative cover 22 and the operation board 14 and the board attachment cover 20 to the door outer plate 1a will be described. First, the board side connector 17 provided on the insulating surface on the back side of the pattern surface of the operation board 14 and the lead wire of the lead wire side connector 11 can be accommodated in a place located above the handle 19 on the left side of the door outer plate 1a. In the opening hole, a board storage case 16 for protecting the board side connector 17, the lead wire, the operation board 14 and the like is provided on the heat insulating material side in the door outer plate 1a.
[0022]
Further, a lead wire side connector 11 for connecting to the substrate side in the substrate storage case 16 is extended from above the substrate storage case 16. The lead wire side connector 11 is electrically connected via an upper hinge portion (not shown) of the refrigerator compartment door 1 from the refrigerator body 10, and the push button 12 provided on the decorative cover 22 is connected to the customer. Can operate each room of the refrigerator according to preference. The substrate storage case 16 is preferably made of resin in order to store lead wires and the like.
[0023]
Further, the pattern surface 13 of the operation board 14 in this embodiment has mounting parts such as a switch, and the insulating surface on the back side of the pattern surface 13 is provided only at the board-side connector 17 at a substantially intermediate portion.
[0024]
Accordingly, it is possible to directly attach the insulating surface to the door outer plate surface 1a, but it is also possible that moisture adheres to the operation substrate 14 due to moisture condensation on the door outer plate surface 1a, and the iron door outer plate 1a. In order to ensure insulation from the surface, a gap is provided between the surface of the door outer plate 1a and the insulating surface on the back side of the pattern surface 13 of the operation substrate 14. This gap is about 1 to 2 mm, and the gap dimension can be secured by the operation board 14 fixing rib provided on the board mounting cover 20 as described above.
[0025]
Further, the size of the board storage case 16 embedded in the heat insulating material is set so that the connector board side connector 17, the connecting lead wire and the lead wire side connector 11 can be inserted (1/2 or less of the board size). By doing so, the hole provided in the iron plate door outer plate 1a can be made smaller accordingly, so the rust countermeasure of the door outer plate 1a which has been a problem with this type of door or the door outer plate 1a is partially deteriorated, It is possible to minimize the distortion of the door outer plate 1a during heat-insulating foaming.
[0026]
That is, in the present embodiment, the board-side connector 17 is arranged on the surface opposite to the push button 12 and the switch arranged on the board 14, and in this embodiment, the pattern surface 13 is pushed. It is formed on the button 12 or switch side.
[0027]
With such a configuration, there is no need to embed a case for storing the entire operation board 14 in the heat insulating material inside the door as in the conventional case, and the operation board can be disposed in the vicinity of the door outer plate, and the inside of the door of the board storage case The depth and depth of the heat insulating material can be minimized.
[0028]
For this reason, when the size of the substrate storage case provided in the door heat insulating material is reduced and the foam heat insulating material is filled between the door outer plate and the door inner plate, the foam heat insulating material spreads inside the door, resulting in poor filling. The occurrence of defective products is reduced, the manufacturing cost of the refrigerator is reduced, and at the same time the reliability is improved. . Furthermore, by miniaturizing the substrate storage case, it is possible to sufficiently secure the thickness of the door heat insulating material, the amount of heat leakage from the outside of the cabinet is reduced, and the power saving effect of the refrigerator can be expected.
[0029]
When the connector and the push button 12 or the switch are on the same board surface and a pattern surface is formed on the opposite side, it is necessary to insulate the pattern surface. It is necessary to cover the substrate, and a predetermined gap is required between the case and the pattern surface of the substrate. Furthermore, as described above, it is necessary to embed the entire case in the heat insulating material on the inside of the door from the problem that reliability is easily lost when the connector and buttons are projected on the door surface. For this reason, the thickness of the heat insulating material of the door in which the board | substrate storage case 16 is arrange | positioned will be reduced significantly.
[0030]
Next, an embodiment in which the insulation between the operation board 14 and the door outer plate 1a is further improved will be described. In order to increase the insulation between the iron door outer plate surface 1a and the insulating surface on the back side of the pattern surface of the operation board 14, a structure in which an insulating material is previously provided on the back side of the pattern surface 13 of the operation board 14 is the best method. is there. FIG. 7 shows an embodiment in which an insulating material is provided. In this embodiment, an insulation sheet 23 made of polyethylene terephthalate as an insulating material is inserted between the surface of the door outer plate 1a and the insulating surface on the back side of the pattern surface 13 of the operation kiban 14 to insulate from the surface of the iron door outer plate 1a. It is a thing that secures sex.
[0031]
As is apparent from the above description, the present embodiment has the following effects.
[0032]
That is, the substrate is mounted with a surface-mounted component on the pattern surface, a substrate-side connector is provided on the insulating surface on the back side of the pattern surface, and the lead wire of the substrate-side connector 17 penetrates the substrate on the pattern surface side. Since the board-side connector is positioned in the storage case, the thickness of the decorative cover can be reduced.
[0033]
In addition, by making the holes in the iron door plate smaller than the size of the board, the area where rust is generated is reduced, and it is easy to take measures against rust on the door plate. For this reason, the steel door plate can be prevented from being distorted.
[0034]
In addition, it is possible to eliminate the need for a connecting rod connecting the push button and the switch, which has been conventionally provided on the operation panel side, leading to a reduction in the number of parts and a reduction in cost. Further, the height of the operation panel 15 protruding from the surface of the door outer plate 1a is lower than the highest portion protruding from the surface of the door outer plate 1a of the handle 19, that is, the top of the handle. Therefore, when the door collides with the wall, furniture, or furniture around the refrigerator when the door is opened or closed, etc. Reliability can be increased.
[0035]
Furthermore, by miniaturizing the substrate storage case, it is possible to sufficiently secure the thickness of the door heat insulating material, the amount of heat leakage from the outside of the cabinet is reduced, and the power saving effect of the refrigerator can be expected.
[0036]
In addition, by covering the solder surface of the board that is placed outward from the door plate surface with a decorative cover, the assembly process to the door plate surface is simplified, and the assembly process to the door plate surface is greatly increased. It can be shortened.
[0037]
In addition, a decorative cover that covers the pattern surface of the substrate is connected to the handle, and a push button for quick cooling, quick freezing, etc. is provided on the decorative cover, and the push button is provided on the decorative cover so as to correspond to the switch arranged on the substrate. Since the switch is turned on and off by pressing the push button, the operation push button connected directly above the handle facilitates the customer's operation and improves the design.
[0038]
In addition, since a gap is provided between the back side of the pattern surface of the board and the surface of the door skin, the insulation performance between the board and the door skin is improved, and water adhering to the surface of the door skin is added to the board. Contact can be prevented, and a highly reliable refrigerator can be provided.
[0039]
Furthermore, the insulation performance can be further improved by adding an insulating member between the back surface of the pattern surface of the substrate and the door outer plate.
