Japanese Patent Laid-Open No. 2000-180047 (pages 4 to 5, FIGS. 1 to 9) Japanese Patent Laid-Open No. 5-256568 (page 3, FIGS. 1 to 6) Japanese Patent Laid-Open No. 6-34266 (page 2 to page 3, FIGS. 1 to 6) Japanese Patent Laid-Open No. 2000-130917 (page 3 to page 5, FIGS. 1 to 8)

冷却庫の代表例として冷蔵庫を取り上げた場合、従来の冷蔵庫においては、庫内灯としてミシン球等の白熱電球を用い、それを庫内の一番奥に配置するという構成が一般的であった。しかしながらミシン球は輝度が低く、庫内が暗くて見づらい上、色温度が２８００Ｋ前後の光色であるため、食品や庫内壁面が黄色がかって見え、食品の鮮度が落ちているように感じられるという欠点があった。また庫内灯の光が貯蔵品の背後から直接目を射て眩しく感じられる上、貯蔵品のラベルが光の影になってしまい、表示内容を読み取り難いという問題もあった。   When a refrigerator is taken up as a typical example of a refrigerator, in a conventional refrigerator, an incandescent bulb such as a sewing machine bulb is used as an interior lamp, and it is generally arranged at the back of the interior. . However, since the sewing balls have low brightness, the interior is dark and difficult to see, and the color temperature is a light color of around 2800K, the food and the inner wall surface appear yellowish, and the freshness of the food seems to be reduced. There was a drawback. In addition, the light of the interior lamp is dazzling when directly shining from behind the stored item, and the label of the stored item becomes a shadow of light, which makes it difficult to read the display contents.

上記のような庫内灯照明の問題点を解決するには様々なアプローチがあるが、庫内灯の光が直接目を射て眩しく感じられるという点については、庫内灯の位置を変えるという解決策が考えられる。すなわち冷蔵室の開口部に庫内灯を配置するのである。しかしながら冷蔵室の開口部は、貯蔵品をスムーズに出し入れできるよう、内側壁が突起物のないフラットな状態であるのが望まれるので、開口部内側壁から突出する形で庫内灯を配置することは好ましくない。開口部内側壁から突出した庫内灯は貯蔵品の出し入れを阻害するばかりでなく、貯蔵品が当たって破損する懸念もある。   There are various approaches to solving the problems of interior lamp lighting as described above, but the point that the light of the interior lamp feels dazzling with direct eyes is to change the position of the interior lamp A solution is possible. That is, the interior lamp is arranged at the opening of the refrigerator compartment. However, it is desirable for the opening of the refrigerator compartment to have a flat inner wall without protrusions so that stored items can be smoothly taken in and out, so the interior lamp is arranged so as to protrude from the inner wall of the opening. That is not preferable. The interior lamp protruding from the inner wall of the opening not only hinders the taking in and out of the stored item, but there is also a concern that the stored item hits and is damaged.

また冷蔵室の扉内面を形成する扉内板には、開口部内側壁に対向する袖壁が形成されている。この袖壁は、開口部からの熱漏洩を抑制すると共に、食品収納ポケットを支持する役割を果たす。このような袖壁が存在することにより、冷蔵室開口部内側壁から庫内灯を突出させる設計は一層非適切になる。   Moreover, the sleeve inner wall which forms the door inner surface of a refrigerator compartment is formed with the sleeve wall facing an opening inner wall. The sleeve wall plays a role of supporting the food storage pocket while suppressing heat leakage from the opening. Due to the presence of such sleeve walls, the design for projecting the interior lamp from the inner wall of the refrigerator compartment opening becomes even more inappropriate.

本発明は上記の点に鑑みてなされたものであり、冷却庫の庫内照明を、貯蔵品の視認がしやすく、また、食品を鮮度良く見せることのできるものに改善することを目的とする。   This invention is made | formed in view of said point, and it aims at improving the illumination in the refrigerator of the refrigerator to the thing which can visually recognize stored goods, and can show food freshly. .

（１）上記目的を達成するために本発明は、冷却室と、該冷却室の扉の開放を検知する扉スイッチと、前記冷却室内に設置され前記扉スイッチの扉開放検知により点灯する庫内灯とを有する冷却庫において、前記庫内灯はＬＥＤを光源とし、前記冷却室の開口部内側壁であって扉内板に形成された袖壁に対向する箇所に埋設されることを特徴としている。   (1) In order to achieve the above object, the present invention provides a cooling chamber, a door switch for detecting the opening of the door of the cooling chamber, and an interior that is installed in the cooling chamber and is lit by detection of the door opening of the door switch. In the refrigerator having a lamp, the interior lamp uses an LED as a light source, and is embedded in a location facing the sleeve wall formed on the inner wall of the opening of the cooling chamber and on the door inner plate. Yes.

この構成によると、庫内灯が手前側から貯蔵品を照明するので、食品ラベルが影にならず、表示を読み取りやすい。光源がＬＥＤであるため、低消費電力で発熱による熱負荷が少なく高照度の庫内照明を得られる上、光の色温度が高いので食品が新鮮に見える。また庫内灯は冷却室の開口部内側壁に埋設されているので貯蔵品の出し入れを阻害しない。加えて、設置場所が扉内板の袖壁に対向する箇所であるため、庫内灯は袖壁によって貯蔵品から保護される。ＬＥＤのカバーを無くすことさえ可能である。   According to this configuration, since the interior lamp illuminates the stored item from the front side, the food label does not become a shadow and the display is easy to read. Since the light source is an LED, it is possible to obtain interior lighting with high power and low heat load due to heat generation and high illuminance, and the food color looks fresh because the color temperature of light is high. Moreover, since the interior lamp is embedded in the inner wall of the opening of the cooling chamber, it does not hinder the taking in and out of stored items. In addition, since the installation location is a location facing the sleeve wall of the door inner plate, the interior lamp is protected from stored items by the sleeve wall. It is even possible to remove the LED cover.

（２）また本発明は、上記構成の冷却庫において、前記扉スイッチと庫内灯とをユニット化したことを特徴としている。   (2) Further, the present invention is characterized in that the door switch and the interior lamp are unitized in the cooler configured as described above.

この構成によると、扉スイッチと庫内灯の配線作業あるいは組付作業をひとまとめにして行うことができ、個別に組み付けるのに比べ組付作業工数を低減できコストを削減できる。   According to this configuration, the wiring work or assembly work of the door switch and the interior lamp can be performed collectively, and the number of assembling work can be reduced and the cost can be reduced as compared with individual assembly.

（３）また本発明は、上記構成の冷却庫において、前記庫内灯を前記扉の少なくとも開放側と枢支側に配置すると共に、開放側の庫内灯から枢支側の庫内灯へと順次点灯させる制御手段を設けたことを特徴としている。   (3) Further, according to the present invention, in the refrigerator having the above-described configuration, the interior lamp is disposed on at least the open side and the pivot side of the door, and from the open side interior lamp to the pivot side interior lamp. And a control means for sequentially lighting them.

この構成によると、扉が開き庫内が視野に入ってくる順に照明されるので、扉を開ける感覚を視覚的に味わうことができる。消費電力に関しても、庫内全体を最初から一挙に明るくするのに比べ節電になる。   According to this structure, since the door is opened and the interior is illuminated in the order in which the interior enters the field of view, it is possible to visually enjoy the feeling of opening the door. In terms of power consumption, it saves energy compared to brightening the entire interior from the beginning.

複数の庫内灯を順次点灯するのに代わり、あるいは複数の庫内灯を順次点灯するのに加えて、庫内灯の輝度を最初は低く、所定時間後に最大輝度となるように制御することができる。このようにすれば、庫内灯の起動電流が抑えられ、所定時間が経過するまで定格電流が流れないので、さらに節電効果を高めることができる。また、使用者が注視する中、消灯状態の庫内灯がいきなり点灯すると、冷蔵庫が故障していたのでないかと誤解される可能性があるが、暗く点灯したものが徐々に明るさを増すという制御を行えば、そのような誤解を招く可能性は小さい。   Instead of lighting multiple interior lights in sequence, or in addition to sequentially turning on multiple interior lights, control the brightness of the interior lights to be low at the beginning and to the maximum brightness after a predetermined time. Can do. In this way, the starting current of the interior lamp is suppressed, and the rated current does not flow until a predetermined time has elapsed, so that the power saving effect can be further enhanced. In addition, when the user turns his eyes off suddenly when the light is turned off suddenly, it may be misunderstood that the refrigerator is out of order. If control is performed, the possibility of such misunderstandings is small.

扉が開いたときに庫内灯を点灯させるには扉開閉検知手段が必要であるが、この扉開閉検知手段が扉の閉め忘れを検知したとき、庫内灯を点滅させ、使用者に対する警告とすることができる。この場合、複数の庫内灯の全部を警告用に使用する必要はないので、扉の開放側を照明する庫内灯のみ点滅あるいは連続点灯させることとして最小限の光量で効率良く警告を行い、警告に使用する電力を削減することができる。   A door open / close detection means is required to turn on the interior light when the door is opened, but when this door open / close detection means detects that the door has been forgotten to close, the interior light blinks to alert the user. It can be. In this case, since it is not necessary to use all of the plurality of interior lights for warning, only the interior lights that illuminate the open side of the door are flashed or continuously lit to efficiently warn with the minimum amount of light, The power used for warning can be reduced.

本発明によると、ＬＥＤを光源とする庫内灯が手前側から貯蔵品を照明するので、高照度で食品ラベルの表示を読み取りやすく、また低消費電力で発熱による熱負荷も少ない庫内照明を得ることができる。庫内灯は冷却室の開口部内側壁に埋設されているので貯蔵品の出し入れを阻害しない上、設置場所が扉内板の袖壁に対向する箇所であるため、貯蔵品からも保護され、ＬＥＤカバーの削減も可能となる。   According to the present invention, since the interior light with the LED as the light source illuminates the stored product from the front side, it is easy to read the food label display with high illuminance, and the interior illumination with low power consumption and less heat load due to heat generation. Obtainable. Since the interior lamp is embedded in the inner wall of the opening of the cooling chamber, it does not hinder the storage and removal of stored items, and since the installation location is the location facing the sleeve wall of the door inner plate, it is also protected from stored items, It is possible to reduce the LED cover.

To do.

第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３はいずれもＬＥＤ（発光ダイオード）を光源とする。ＬＥＤは１個の庫内灯ユニットにつき１個だけ配置してもよく、複数個配置してもよい。第２冷蔵室１２の庫内のうち、左寄りの領域は主として第１庫内灯ユニット３１で照明され、中央の領域は主として第２庫内灯ユニット３２で照明され、右寄りの領域は主として第３庫内灯ユニット３３で照明される。   Each of the first interior lamp unit 31, the second interior lamp unit 32, and the third interior lamp unit 33 uses an LED (light emitting diode) as a light source. Only one LED may be arranged per one interior lamp unit, or a plurality of LEDs may be arranged. Of the interior of the second refrigerator compartment 12, the left area is mainly illuminated by the first interior lamp unit 31, the central area is mainly illuminated by the second interior lamp unit 32, and the right area is mainly third. Illuminated by the interior lamp unit 33.

第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３は、ＬＥＤを回路基板に装着し、これにケースを組み合わせたものである。その構造を図２及び図３に基づき説明する。図２、３に示すのは第１庫内灯ユニット３１であるが、第２庫内灯ユニット３２と第３庫内灯ユニット３３も基本的には同じ構造となっている。   The 1st interior lamp unit 31, the 2nd interior lamp unit 32, and the 3rd interior lamp unit 33 attach LED to a circuit board, and combine this with a case. The structure will be described with reference to FIGS. 2 and 3 show the first interior lamp unit 31, the second interior lamp unit 32 and the third interior lamp unit 33 basically have the same structure.

第１庫内灯ユニット３１では、回路基板４０にＬＥＤ４１が実装されている。回路基板４０には扉スイッチ４２も実装される。扉スイッチ４２は近接スイッチであり、磁石によってＯＮ／ＯＦＦする。ＬＥＤ４１と扉スイッチ４２には電力供給ライン４３を通じて給電する。回路基板４０は合成樹脂製のケース４４に収納されるものであり、ケース４４の一部にはＬＥＤ４１の放つ光を透過させる照明窓４５が設けられる。照明窓４５は透明合成樹脂製の透光カバーで覆われている。透光カバーはケース４４の外に出る光を拡散させる役割を果たす。   In the first interior lamp unit 31, the LED 41 is mounted on the circuit board 40. A door switch 42 is also mounted on the circuit board 40. The door switch 42 is a proximity switch and is turned ON / OFF by a magnet. Power is supplied to the LED 41 and the door switch 42 through the power supply line 43. The circuit board 40 is accommodated in a case 44 made of synthetic resin, and an illumination window 45 that transmits light emitted from the LED 41 is provided in a part of the case 44. The illumination window 45 is covered with a transparent cover made of transparent synthetic resin. The translucent cover serves to diffuse the light that goes out of the case 44.

冷蔵室１２の内面を構成するのは合成樹脂製の内板５０である。内板５０には、第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３のそれぞれの取付位置にポケット部５１が形成されている。この箇所は扉２２の扉内板５２に形成された袖壁５３に対向する箇所でもある。第１庫内灯ユニット３１のケース４４の外面には弾性係合爪４６が形成され、ポケット部５１の内側面には弾性係合爪４６を係合させる穴５４が形成されている。   The inner surface 50 of the refrigerator compartment 12 is an inner plate 50 made of synthetic resin. In the inner plate 50, pocket portions 51 are formed at the mounting positions of the first interior lamp unit 31, the second interior lamp unit 32, and the third interior lamp unit 33. This location is also a location facing the sleeve wall 53 formed on the door inner plate 52 of the door 22. An elastic engagement claw 46 is formed on the outer surface of the case 44 of the first internal lamp unit 31, and a hole 54 for engaging the elastic engagement claw 46 is formed on the inner side surface of the pocket portion 51.

ポケット部５１に第１庫内灯ユニット３１を押し込むと、限界まで押し込んだ時点で弾性係合爪４６が穴５４に係合し、第１庫内灯ユニット３１は内板５０に埋設状態で固定される。埋設状態であるため、貯蔵品の出し入れを妨げず、袖壁５３の進入の邪魔になることもない。第２庫内灯ユニット３２と第３庫内灯ユニット３３も同様に埋設状態で取り付けられる。   When the first interior lamp unit 31 is pushed into the pocket 51, the elastic engagement claw 46 engages with the hole 54 when the first interior lamp unit 31 is pushed to the limit, and the first interior lamp unit 31 is fixed to the inner plate 50 in an embedded state. Is done. Since it is an embedded state, it does not hinder the storage and removal of stored items, and does not obstruct the entry of the sleeve wall 53. Similarly, the second interior lamp unit 32 and the third interior lamp unit 33 are attached in an embedded state.

３個の庫内灯ユニットのうち、第１庫内灯ユニット３１のみが扉スイッチ４２も含めた形でユニット化されている。第１庫内灯ユニット３１に対向する袖壁５３の内部には扉スイッチ４２をＯＮ／ＯＦＦさせる磁石５５が取り付けられている。   Of the three interior lamp units, only the first interior lamp unit 31 is unitized including the door switch 42. A magnet 55 for turning on / off the door switch 42 is attached to the inside of the sleeve wall 53 facing the first interior lamp unit 31.

図２において、５６は扉２４の内面周縁部に取り付けられた扉パッキンであるガスケットである。ガスケット５６は断熱筐体１０の外殻を構成する鋼板に吸着するゴム磁石５７を備えている。   In FIG. 2, reference numeral 56 denotes a gasket that is a door packing attached to the inner peripheral edge of the door 24. The gasket 56 includes a rubber magnet 57 that is attracted to a steel plate that forms the outer shell of the heat insulating housing 10.

第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３のＬＥＤの点灯制御を行うのは図４に示す制御装置６０である。制御装置６０は第１庫内灯ユニット３１、第２庫内灯ユニット３２、第３庫内灯ユニット３３を、遅延設定回路６１、６２、６３を介して点灯制御する。   It is the control device 60 shown in FIG. 4 that controls the lighting of the LEDs of the first interior lamp unit 31, the second interior lamp unit 32, and the third interior lamp unit 33. The control device 60 controls lighting of the first interior lamp unit 31, the second interior lamp unit 32, and the third interior lamp unit 33 via delay setting circuits 61, 62, and 63.

制御装置６０には扉スイッチ４２と温度センサ６４も接続される。扉スイッチ４２は扉２２ばかりでなく扉２１、２３、２４にもそれぞれ設けられ、どの扉が開状態でどの扉が閉状態であるかを検知する。温度センサ６４は第１冷蔵室１１、第２冷蔵室１２、野菜室１３、及び冷凍室１４のそれぞれに対して設けられ、各室の温度を検知する。加えて制御装置６０は、庫内冷却用の冷凍機６５を駆動回路６６を介して制御し、また第１冷蔵室１１、第２冷蔵室１２、野菜室１３、及び冷凍室１４の各室に冷気を分配するダンパ６７を駆動回路６８を介して制御する。   A door switch 42 and a temperature sensor 64 are also connected to the control device 60. The door switch 42 is provided not only on the door 22 but also on the doors 21, 23, 24, and detects which door is open and which door is closed. A temperature sensor 64 is provided for each of the first refrigerator compartment 11, the second refrigerator compartment 12, the vegetable compartment 13, and the freezer compartment 14, and detects the temperature of each compartment. In addition, the control device 60 controls the refrigerator 65 for cooling the inside of the refrigerator via the drive circuit 66, and in each of the first refrigerator compartment 11, the second refrigerator compartment 12, the vegetable compartment 13, and the freezer compartment 14. A damper 67 for distributing cool air is controlled via a drive circuit 68.

次に第２冷蔵室１２の庫内灯点灯動作につき説明する。扉２２を開けると磁石５５が扉スイッチ４２から離れるので、扉２２の開放が扉スイッチ４２によって検知される。扉２２の開放検知に基づき制御装置６０は第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３を点灯させる。この時、遅延設定回路６１、６２、６３による点灯遅延時間に差をもたせ、第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３が所定順序で互いに時間差をもって点灯するようにしておく。   Next, the interior lamp lighting operation of the second refrigerator compartment 12 will be described. Since the magnet 55 moves away from the door switch 42 when the door 22 is opened, the opening of the door 22 is detected by the door switch 42. Based on the detection of opening of the door 22, the control device 60 turns on the first interior lamp unit 31, the second interior lamp unit 32, and the third interior lamp unit 33. At this time, there is a difference in the lighting delay time by the delay setting circuits 61, 62, 63, and the first interior lamp unit 31, the second interior lamp unit 32, and the third interior lamp unit 33 are time-different from each other in a predetermined order. Keep it on.

まず、扉２２の開放側に配置された第１庫内灯ユニット３１を最初に点灯させる。すなわち第１庫内灯ユニット３１の点灯遅延時間はゼロないし非常に短い時間とする。続いて、所定時間差をもって、第２庫内灯ユニット３２を点灯させる。最後に、さらに所定時間差をもって、扉２２の枢支側に配置された第３庫内灯ユニット３３を点灯させる。これにより第２冷蔵室１２の庫内は、左寄りの領域、中央の領域、最後に右寄りの領域と、順次照明されることになる。   First, the 1st interior lamp unit 31 arrange | positioned at the open | release side of the door 22 is lighted first. That is, the lighting delay time of the first interior lamp unit 31 is zero or very short. Subsequently, the second interior lamp unit 32 is turned on with a predetermined time difference. Finally, the third interior lamp unit 33 disposed on the pivot side of the door 22 is turned on with a predetermined time difference. As a result, the interior of the second refrigerator compartment 12 is sequentially illuminated with a leftward region, a central region, and finally a rightward region.

このように、扉２２を開けるとき、開放側の庫内灯ユニットから枢支側の庫内灯ユニットへと順次点灯して行くから、扉２２が開いて冷蔵室１２の庫内が視野に入ってくる順に照明されるので、扉を開ける感覚を視覚的に味わうことができる。また消費電力に関しても、冷蔵室１２の庫内全体を最初から一挙に明るくするのに比べ節電になる。   In this way, when the door 22 is opened, the door-side interior light unit sequentially lights from the open-side interior light unit to the pivot-side interior light unit, so the door 22 opens and the interior of the refrigerator compartment 12 enters the field of view. The lights are illuminated in the order they come, so you can visually feel the feeling of opening the door. In addition, the power consumption is also reduced compared to making the entire refrigerator compartment 12 brighter from the beginning.

第１庫内灯ユニット３１、第２庫内灯ユニット３２、及び第３庫内灯ユニット３３はいずれも手前側から貯蔵品を照明するので、食品ラベルが影にならず、表示を読み取りやすい。光源がＬＥＤであるため、低消費電力で発熱による熱負荷が少なく高照度の庫内照明を得られる上、光の色温度が高いので食品が新鮮に見え、使用感が良い。また庫内灯ユニットはいずれも冷蔵室１２の開口部内側壁に埋設されているので、貯蔵品の出し入れも袖壁５３の進入も阻害することはない。設置場所が袖壁５３に対向する箇所であるため、庫内灯ユニットは袖壁５３によって貯蔵品から保護され、ＬＥＤの透光カバーを無くすことさえ可能となる。   Since the first interior light unit 31, the second interior light unit 32, and the third interior light unit 33 all illuminate the stored items from the front side, the food label does not become a shadow, and the display is easy to read. Since the light source is an LED, it is possible to obtain interior lighting with high power and low heat load due to heat generation and high illuminance, and since the color temperature of light is high, the food looks fresh and the feeling of use is good. Moreover, since all the interior lamp units are embedded in the inner wall of the opening of the refrigerating chamber 12, neither the taking in / out of stored items nor the entry of the sleeve wall 53 is hindered. Since the installation location is the location facing the sleeve wall 53, the interior lamp unit is protected from the stored items by the sleeve wall 53, and it is even possible to eliminate the translucent cover of the LED.

第１庫内灯ユニット３１に対して設けられた遅延設定回路６１は、第１庫内灯ユニット３１の点灯遅延時間を常にゼロに固定するのであれば、省略可能である。   The delay setting circuit 61 provided for the first interior lamp unit 31 can be omitted if the lighting delay time of the first interior lamp unit 31 is always fixed to zero.

扉スイッチ４２が扉２２の閉め忘れを検知したとき、庫内灯ユニットのＬＥＤを点滅させ、使用者に対する警告とすることができる。この場合、３個の庫内灯ユニットの全部を警告用に使用する必要はないので、扉２２の開放側を照明する第１庫内灯ユニット３１のＬＥＤ４１のみ点滅あるいは連続点灯させることとして最小限の光量で効率良く警告を行い、警告に使用する電力を削減することができる。   When the door switch 42 detects that the door 22 has been forgotten to be closed, the LED of the interior light unit can be blinked to provide a warning to the user. In this case, since it is not necessary to use all the three interior lamp units for warning, it is the minimum that only the LED 41 of the first interior lamp unit 31 that illuminates the open side of the door 22 blinks or is continuously lit. The warning can be performed efficiently with the amount of light, and the power used for the warning can be reduced.

上記のような複数の庫内灯ユニットによる庫内順次照明の仕組みは、第２冷蔵室１２ばかりでなく、第１冷蔵室１１、野菜室１３、及び冷凍室１４にも必要に応じ適用することができる。   The mechanism of the sequential lighting by the plurality of interior lighting units as described above is applied not only to the second refrigerator compartment 12, but also to the first refrigerator compartment 11, the vegetable compartment 13, and the freezer compartment 14 as necessary. Can do.

以上、本発明の実施形態につき説明したが、本発明の範囲はこれに限定されるものではなく、発明の主旨を逸脱しない範囲で種々の変更を加えて実施することができる。   Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention.

本発明は庫内灯を備えた冷蔵庫全般に利用可能である。     The present invention is applicable to all refrigerators equipped with an interior lamp.
