Description

本発明の実施形態は貯蔵庫に関する。 Embodiments of the present invention relate to storage.

従来より、冷蔵庫や冷凍庫あるいは温蔵庫等の貯蔵庫においては、庫内の貯蔵室を照明する庫内灯が設けられている。この庫内灯は、貯蔵室の側面や奥面など室壁面に設けられており、その室壁面から貯蔵室を照明するようになっている。 Conventionally, in a storage such as a refrigerator, a freezer, or a hot storage, an internal light is provided to illuminate the storage room in the refrigerator. This interior light is provided on the wall surface of the room such as the side surface and the back surface of the storage room, and the storage room is illuminated from the wall surface of the room.

しかしながら、そのように貯蔵室の室壁面から貯蔵室を照明するものでは、庫内灯の近辺に貯蔵品が置かれることがあり、その場合、照明が貯蔵品で遮られ、貯蔵室に対する照度の低下が大きくなる。又、貯蔵室の奥面に庫内灯が設けられたものでは、扉を開けて貯蔵室を覗く使用者の目に庫内灯の照射した光が直接入り、まぶしく感じられる。 However, in such a case where the storage room is illuminated from the wall surface of the storage room, the storage item may be placed in the vicinity of the interior light, in which case the lighting is blocked by the storage item and the illuminance to the storage room is increased. The drop will be greater. In addition, in the case where the interior light is provided on the back surface of the storage room, the light radiated by the internal light directly enters the eyes of the user who opens the door and looks into the storage room, and feels dazzling.

それに対して、貯蔵室に面する扉の背面部に存在するスロート部に庫内灯を設けたものが存在する(例えば特許文献1参照)。 On the other hand, there is a throat portion provided on the back surface of the door facing the storage chamber with an internal light (see, for example, Patent Document 1).

特開平11−83306号公報Japanese Unexamined Patent Publication No. 11-83306

上述の、扉のスロート部に庫内灯を設けたものでは、扉を開けたときの庫内灯の近辺に貯蔵品が置かれることがなく、従って、照明が貯蔵品で遮られることがなく、貯蔵室に対する照度の低下が大きくなることはない。又、扉を開けて貯蔵室を覗く使用者の目に庫内灯の照射した光が直接目に入るということもなく、まぶしく感じられることが少ない。 In the case where the interior light is provided in the throat of the door as described above, no stored items are placed in the vicinity of the internal light when the door is opened, and therefore the lighting is not obstructed by the stored items. , The decrease in illuminance for the storage room does not increase significantly. In addition, the light radiated by the internal light does not directly enter the eyes of the user who opens the door and looks into the storage room, and the user does not feel dazzling.

しかしながら、扉のスロート部に庫内灯を設けた関係上、扉の開放時、庫内灯の照射した光が扉による影を作ることがあり得るものであり、特に90度角超の角度で扉が開放されたときには、その影を作ることが多分にあり得て、それにより、庫内の照明範囲が一部欠如し、庫内の充分な照明効果が得られないという問題点を有していた。 However, since the interior light is provided in the throat of the door, the light emitted by the interior light may cast a shadow due to the door when the door is opened, especially at an angle of more than 90 degrees. When the door is opened, it is likely that it will cast a shadow, which has the problem that the lighting range inside the refrigerator is partially lacking and the sufficient lighting effect inside the refrigerator cannot be obtained. Was there.

そこで、扉のスロート部に照明装置を設けたもので、庫内の照明範囲が一部欠如することがなく、庫内の充分な照明効果を得ることのできる貯蔵庫を提供する。 Therefore, a lighting device is provided in the throat portion of the door to provide a storage that can obtain a sufficient lighting effect in the storage without partially lacking the lighting range in the storage.

本実施形態の貯蔵庫は、内部に貯蔵室を有し、その貯蔵室に通じる開口部を前面に有する庫本体と、この庫本体の前記開口部を開閉するように設けられ、前記貯蔵室に面する背面部にスロート部を有する扉と、この扉の前記スロート部に設けられて、その扉の開放時に前記貯蔵室を照明する照明装置とを具備し、その照明装置を、それの照射する光が前記扉による影を作らないように設ける。 The storage of the present embodiment is provided so as to open and close a storage main body having a storage chamber inside and an opening leading to the storage chamber on the front surface and the opening of the storage main body, and facing the storage chamber. A door having a throat portion on the back surface portion and a lighting device provided on the throat portion of the door to illuminate the storage room when the door is opened, and the illuminating device is irradiated with light. Is provided so as not to cast a shadow due to the door.

Then, there is another door 17 on the right side, and this door 17 also opens and closes the opening 8 on the front surface of the refrigerator compartment 6, and the outer plate 18 and the inner plate 19 are connected by the peripheral frame 20. In combination, these are filled with a foamed heat insulating material (also particularly a foamed heat insulating material, particularly polyurethane foam) 21.

すなわち、冷蔵室6の前面の開口部8は、扉2と扉17の2枚の扉で開閉するようにしており、詳しくは図示しないが、扉2は左端部を庫本体1に軸支し、扉17は右端部を庫本体1に軸支して、それぞれその各軸支部分を中心に回動する開き戸式で且つ観音開き式に開閉可能に設けている。なお、左側の扉2には、左右間の仕切部材22を、扉2の開放に支障を来たさない可動構造で取付けている。 That is, the opening 8 on the front surface of the refrigerator compartment 6 is opened and closed by two doors, the door 2 and the door 17, and although not shown in detail, the left end of the door 2 is pivotally supported by the storage body 1. The right end of the door 17 is pivotally supported by the refrigerator body 1, and each of the doors 17 is provided to be openable and closable in a hinged door type and a double door type that rotates around each shaft support portion. A partition member 22 between the left and right sides is attached to the left door 2 with a movable structure that does not hinder the opening of the door 2.

扉2,17は、それぞれ冷蔵室6に面する背面部である内板14,19の背面にスロート部23,24を有している。これらのスロート部23,24は、図4に扉2のスロート部23で代表して示すように、内板14,19の各背面の周囲部から矩形の枠状に突出するように形成したもので、中空である。又、これらのスロート部23,24の各囲繞空間には、図1から図3に示すように、ポケット部25,26を複数段に設けている。そして、これらのスロート部23,24の各軸支部分側で上下方向に延びる一辺部の上下の中間部には、それぞれ照明装置27,28を設けている。 The doors 2 and 17 have throat portions 23 and 24 on the back surfaces of the inner plates 14 and 19 which are the back surface portions facing the refrigerator compartment 6, respectively. These throat portions 23, 24 are formed so as to project in a rectangular frame shape from the peripheral portions of the back surfaces of the inner plates 14 and 19, as represented by the throat portion 23 of the door 2 in FIG. And it's hollow. Further, as shown in FIGS. 1 to 3, pocket portions 25 and 26 are provided in a plurality of stages in the surrounding spaces of the throat portions 23 and 24. Lighting devices 27 and 28 are provided in the upper and lower intermediate portions of one side portion extending in the vertical direction on each of the shaft support portions of the throat portions 23 and 24, respectively.

図5及び図6は、上記照明装置27,28の詳細を、扉2の照明装置27で代表して示しており、スロート部23,24の内部に光源取付具29を組込んでいる。この光源取付具29は、全体にスロート部23,24の内面に添う容器状のもので、前側(図6では下側)が開口し、後側(同上側)ほど薄くなった先薄状で、先端部が閉塞されている。 5 and 6 show the details of the lighting devices 27 and 28 as represented by the lighting device 27 of the door 2, and the light source attachment 29 is incorporated in the throat portions 23 and 24. The light source fixture 29 has a container-like shape that follows the inner surfaces of the throat portions 23 and 24 as a whole, and has a tapered shape in which the front side (lower side in FIG. 6) is open and the rear side (upper side) is thinner. , The tip is blocked.

従って、スロート部23,24並びに光源取付具29は、ともに両側壁部が先端ほど接近する斜面状を成していて、且つ、スロート部23,24の各表側部である外側壁部は寸法D(特にはスロート部23,24の各板厚以上)の段差を有し、この段差の低い方の部分に、段差の境界部分に接して開口部30を、プラスチックによるスロート部23,24の型成形における型抜きにより形成している。 Therefore, both the throat portions 23 and 24 and the light source attachment 29 have a slope shape in which both side wall portions approach each other toward the tip, and the outer wall portion which is each front side portion of the throat portions 23 and 24 has dimension D. It has a step (particularly more than the thickness of each of the throat portions 23 and 24), and the opening 30 is in contact with the boundary portion of the step in the lower portion of the step, and the mold of the throat portions 23 and 24 made of plastic. It is formed by die cutting in molding.

又、光源取付具29の表側部である外側壁にも、上記スロート部23,24の開口部30より若干小さな開口部31を形成すると共に、その開口部31の周縁部から周囲外方へ張り出すフランジ(先部フランジ)32を形成しており、開口部31に面する内部には光源保持部である保持爪33を設けている。光源取付具29の基部には、これもその周縁部から周囲外方へ張り出すフランジ(基部フランジ)34を形成している。 Further, an opening 31 slightly smaller than the opening 30 of the throat portions 23 and 24 is also formed on the outer wall which is the front side portion of the light source attachment 29, and is stretched outward from the peripheral edge of the opening 31. A flange (tip flange) 32 is formed, and a holding claw 33, which is a light source holding portion, is provided inside facing the opening 31. The base of the light source fixture 29 is also formed with a flange (base flange) 34 that projects outward from the peripheral edge thereof.

この構成で、スロート部23,24の内部に光源取付具29を挿入し、スロート部23,24の前記開口部30対向する内面23a,24a(図6に23aのみ図示)に、光源取付具29の表側部と対向する背面部29aを当接させると共に、スロート部23,24の上記開口部30の周縁部より外方の部分の内面23b,24b(図6に23bのみ図示)に、光源取付具29の先部フランジ32の外面32aを当接させている。 With this configuration, the light source fixture 29 is inserted inside the throat portions 23, 24, and the light source fixture 29 is inserted into the inner surfaces 23a, 24a of the throat portions 23, 24 facing the opening 30 (only 23a is shown in FIG. 6). The back surface portion 29a facing the front side portion of the above is brought into contact with the inner surface 23b, 24b (only 23b is shown in FIG. 6) of the throat portions 23, 24 outside the peripheral edge portion of the opening 30. The outer surface 32a of the tip flange 32 of the tool 29 is brought into contact with the tool 29.

そして、扉2,17の外板13,18の内部には、コネクタハウジング35を組込んでいる。このコネクタハウジング35には、後壁部のほゞ中央にはリード線挿通孔36を形成している。 The connector housing 35 is incorporated in the outer plates 13 and 18 of the doors 2 and 17. The connector housing 35 is formed with a lead wire insertion hole 36 in the center of the rear wall portion.

この後、照明装置27,28の光源であるLED37を実装した回路基板38が有するリード線39を、光源取付具29内からコネクタハウジング35のリード線挿通孔36を通してコネクタハウジング35内に導出し、このリード線39が先端部に有する出力側のコネクタ40を、外部リード線41が先端部に有する入力側のコネクタ42に接続している。その後、それらの接続部をリード線挿通孔36から光源取付具29内に戻し入れ、外部リード線41のコネクタ42近傍の部分にあらかじめ一体化したシール43をリード線挿通孔36に圧入してリード線挿通孔36を密閉している。外部リード線41は、前記庫本体1から扉2の軸支部分中を通してLED37に給電をするものである。 After that, the lead wire 39 of the circuit board 38 on which the LED 37 which is the light source of the lighting devices 27 and 28 is mounted is led out from the light source fixture 29 through the lead wire insertion hole 36 of the connector housing 35 into the connector housing 35. The output-side connector 40 of the lead wire 39 at the tip is connected to the input-side connector 42 of the external lead wire 41 at the tip. After that, those connection portions are returned from the lead wire insertion hole 36 into the light source fitting 29, and the seal 43 pre-integrated in the portion of the external lead wire 41 near the connector 42 is press-fitted into the lead wire insertion hole 36 to lead. The wire insertion hole 36 is sealed. The external lead wire 41 supplies power to the LED 37 from the main body 1 through the shaft support portion of the door 2.

そして、その後、扉2,17の外板13,18の内部に前記発泡断熱材16,21を注入し、内板14,19を外板13,18にそれぞれ前記周側枠15,20で組合わせ結合する。又、このとき、前記光源取付具29の基部フランジ34の前面には、あらかじめシール(例えばソフトテープ)44を貼着しておき、このシール44に、コネクタハウジング35の後面(リード線挿通孔36の周囲部分)を圧接させることにより、前記光源取付具29の内部を外板13,18の内部(発泡断熱材16,21の充填空間)から密閉している。これにより、外板13,18の内部に注入した発泡断熱材16,21は、光源取付具29の内部に侵入することなく、扉2では外板13と内板14との間、扉17では外板18と内板19との間に、それぞれ充填される。 After that, the foamed heat insulating materials 16 and 21 are injected into the outer plates 13 and 18 of the doors 2 and 17, and the inner plates 14 and 19 are assembled to the outer plates 13 and 18 by the peripheral frames 15 and 20, respectively. Combine and combine. At this time, a seal (for example, soft tape) 44 is attached to the front surface of the base flange 34 of the light source attachment 29 in advance, and the rear surface (lead wire insertion hole 36) of the connector housing 35 is attached to the seal 44. The inside of the light source connector 29 is sealed from the inside of the outer plates 13 and 18 (the filling space of the foamed heat insulating materials 16 and 21) by pressing the peripheral portion of the light source fixture 29. As a result, the foamed heat insulating materials 16 and 21 injected into the outer plates 13 and 18 do not invade the inside of the light source fixture 29, and are between the outer plate 13 and the inner plate 14 in the door 2 and in the door 17. It is filled between the outer plate 18 and the inner plate 19, respectively.

更にその後、上記回路基板38を光源取付具29の開口部31から保持爪33に係合させて装着しており、この後、前記スロート部23,24の開口部30から光源取付具29の開口部31に、シェード45を複数の取付爪45aにより装着して開口部30,31を閉塞している。シェード45はLED37の照射する光を拡散するものであり、光源取付具29の開口部31よりは大きいものの、スロート部23,24の開口部30に収まるサイズの矩形で、装着状態では表面部がスロート部23,24の表面部とほゞ面一に位置している。 After that, the circuit board 38 is mounted by engaging with the holding claw 33 from the opening 31 of the light source mounting tool 29, and then the opening of the light source mounting tool 29 is mounted from the opening 30 of the throat portions 23 and 24. The shade 45 is attached to the portion 31 by a plurality of attachment claws 45a to close the openings 30 and 31. The shade 45 diffuses the light emitted by the LED 37, and although it is larger than the opening 31 of the light source fixture 29, it is a rectangle having a size that fits in the openings 30 of the throat portions 23 and 24, and the surface portion is in the mounted state. It is located almost flush with the surface of the throat portions 23 and 24.

なお、扉17の照明装置28は、上記扉2の照明装置27とは左右対称の構造で設けている。
図1は、以上のように照明装置27,28を組込んだ扉2,17を全開の開放状態で表しており、この図1で明らかなように、照明装置27,28のLED37からシェード45を透して前記冷蔵室6に照射される光の照射範囲L1,L2はそれぞれ扉2,17(特にはそれらの軸支側の端縁部)にかからないようにしており、すなわち、光の照射範囲L1中には扉2が、光の照射範囲L1中には扉17が、それぞれ位置することのないようにしていて、それにより、照明装置27,28の照射する光が扉2,17による影を作らないようにしている。
The lighting device 28 of the door 17 is provided with a structure symmetrical to that of the lighting device 27 of the door 2.
FIG. 1 shows the doors 2 and 17 in which the lighting devices 27 and 28 are incorporated as described above in a fully open state, and as is clear from FIG. 1, the LED 37 to the shade 45 of the lighting devices 27 and 28 are shown. The irradiation ranges L 1 and L 2 of the light radiated to the refrigerating chamber 6 through the doors 2 and 17 do not cover the doors 2 and 17 (particularly the edge portions on the shaft support side thereof), that is, the light. irradiation range L 1 door 2 during the door 17 in the irradiation range L 1 of the light, have as not to position respectively, whereby the door irradiating light of the lighting device 27, 28 I try not to cast shadows by 2 and 17.

加えて、図1から図3には、照明装置27,28に対応して庫本体1の断熱壁中に設けた扉開閉検知手段であるスイッチ46,47を示しており、これらは例えばタクトスイッチやマイクロスイッチであって、詳しくは図示しないが、ともに庫本体1の内部に突出した突子が扉2,17の閉鎖によりスロート部23,24(各軸支部分側の一辺部)で押圧されることによって、扉2,17の閉鎖を検知し、その突子の押圧が扉2,17の開放により解除されることにより、扉2,17の開放を検知するようになっている。なお、図2に示すように、スイッチ46,47は照明装置27,28と直接接触することのない位置に設置している。照明装置27,28は、このスイッチ46,47が扉2,17の開放を検知したときにLED37を発光させ、扉2,17の閉鎖を検知したときにLED37を消光させるようになっている。 In addition, FIGS. 1 to 3 show switches 46, 47 which are door open / close detection means provided in the heat insulating wall of the refrigerator body 1 corresponding to the lighting devices 27, 28, and these are, for example, tact switches. And microswitches, which are not shown in detail, but both of which have protrusions protruding inside the main body 1 are pressed by the throat portions 23 and 24 (one side of each shaft support portion) due to the closing of the doors 2 and 17. As a result, the closing of the doors 2 and 17 is detected, and the pressing of the protrusion is released by the opening of the doors 2 and 17, so that the opening of the doors 2 and 17 is detected. As shown in FIG. 2, the switches 46 and 47 are installed at positions where they do not come into direct contact with the lighting devices 27 and 28. The lighting devices 27 and 28 cause the LED 37 to emit light when the switches 46 and 47 detect the opening of the doors 2 and 17, and extinguish the LED 37 when the switches 46 and 47 detect the closing of the doors 2 and 17.

更に、図5及び図6には、扉2,17のスロート部23,24の外側近傍において内板14,19に形成した溝48を示しており、この溝48は、扉2,17の閉鎖時に庫本体1の開口部8の密閉をするガスケット(図示せず)を差込みにより取付けるためのもので、そのガスケット差込み用の開口部48aの両側にガスケットの抜止めをする突部48bを有している。 Further, FIGS. 5 and 6 show grooves 48 formed in the inner plates 14 and 19 in the vicinity of the outer side of the throat portions 23 and 24 of the doors 2 and 17, and the grooves 48 close the doors 2 and 17. Sometimes, a gasket (not shown) for sealing the opening 8 of the main body 1 is attached by insertion, and there are protrusions 48b for retaining the gasket on both sides of the opening 48a for inserting the gasket. ing.

次に、上記構成の冷蔵庫の作用を述べる。
上記構成の冷蔵庫においては、扉2,17を開放すると、スイッチ46,47が扉2,17の開放を検知することにより、照明装置27,28のLED37を発光させ、図1に照射範囲L1,L2で示したように、冷蔵室6を照明する。
Next, the operation of the refrigerator having the above configuration will be described.
In the refrigerator having the above configuration, when the doors 2 and 17 are opened, the switches 46 and 47 detect the opening of the doors 2 and 17 to cause the LED 37 of the lighting devices 27 and 28 to emit light, and the irradiation range L 1 is shown in FIG. , L 2 Illuminates the refrigerator compartment 6.

又、この場合、扉2,17の一方のみを開放すると、スイッチ46,47のうちの開放された扉側のスイッチが扉の開放を検知することにより、照明装置27,28のうちの開放された扉側の照明装置のLED37を発光させ、冷蔵室6を照明する。すなわち、この場合には、扉2,17のうちの開放された扉側の照明装置のLED37を発光させることのみを行い、開放されない扉側の照明装置のLED37を発光させることは行わない。これにより、消費電力の節減を図っている。 Further, in this case, when only one of the doors 2 and 17 is opened, the opened door-side switch of the switches 46 and 47 detects the opening of the door, so that the lighting devices 27 and 28 are opened. The LED 37 of the lighting device on the door side is made to emit light to illuminate the refrigerator compartment 6. That is, in this case, only the LED 37 of the lighting device on the open door side of the doors 2 and 17 is made to emit light, and the LED 37 of the lighting device on the door side that is not opened is not made to emit light. This saves power consumption.

そして、上記構成の冷蔵庫においては、照明装置27,28を扉2,17のスロート部23,24に設けており、冷蔵室6の室壁面に庫内灯を設けたもののような、扉2,17を開けたときの照明装置27,28の近辺に貯蔵品が置かれることがないので、照明が貯蔵品で遮られることがなく、従って、冷蔵室6に対する照度の低下が大きくなることがなく、且つ、扉2,17を開けて冷蔵室6を覗く使用者の目に照射光が直接目に入るということもなくて、使用者にまぶしく感じられることが少ない。 In the refrigerator having the above configuration, the lighting devices 27 and 28 are provided in the throat portions 23 and 24 of the doors 2 and 17, and the doors 2 and 2 are similar to those in which the interior light is provided on the wall surface of the refrigerator compartment 6. Since no stored items are placed in the vicinity of the lighting devices 27 and 28 when the 17 is opened, the lighting is not obstructed by the stored items, and therefore the decrease in illuminance with respect to the refrigerator compartment 6 is not large. Moreover, since the irradiation light does not directly enter the eyes of the user who opens the doors 2 and 17 and looks into the refrigerator compartment 6, the user is less likely to feel dazzling.

併せて、上記構成の冷蔵庫においては、照明装置27,28を扉2,17のスロート部23,24に設けたものにおいても、照明装置27,28の照射する光が扉2,17による影を作らないようにしており、それによって、その各照射範囲L1,L2に扉2,17による影ができず、庫内の照明範囲が一部欠如することがなくて、庫内の充分な照明効果を得ることができる。 At the same time, in the refrigerator having the above configuration, even if the lighting devices 27 and 28 are provided on the throat portions 23 and 24 of the doors 2 and 17, the light emitted by the lighting devices 27 and 28 casts a shadow by the doors 2 and 17. It is not made, so that the respective irradiation ranges L 1 and L 2 are not shaded by the doors 2 and 17, and the lighting range in the refrigerator is not partially lost, which is sufficient in the refrigerator. A lighting effect can be obtained.

又、上記構成の冷蔵庫においては、照明装置27,28を、光源であるLED37と、このLED37を取付ける光源取付具29とを有する構成とし、その光源取付具29には、LED37の照射光を拡散するシェード45を装着する開口部31と、この開口部31の周縁部から外方に張り出す先部フランジ32とを表側部に設け、扉2,17のスロート部23,24の内部空間を扉2,17の発泡断熱材充填空間から密閉するための基部フランジ34を基部に設けていて、扉2,17のスロート部23,24には上記シェード45を収容する開口部30を形成し、この開口部30と対向するスロート部23,24の内面23a,24aに、上記光源取付具29の表側部と対向する背面部29aを当接させ、該スロート部23,24の開口部30の周縁部より外方の部分の内面23b,24bに、光源取付具29の先部フランジ32の外面32aを当接させている。 Further, in the refrigerator having the above configuration, the lighting devices 27 and 28 are configured to include an LED 37 as a light source and a light source attachment 29 for attaching the LED 37, and the irradiation light of the LED 37 is diffused to the light source attachment 29. An opening 31 for mounting the shade 45 and a tip flange 32 protruding outward from the peripheral edge of the opening 31 are provided on the front side portion, and the internal space of the throat portions 23 and 24 of the doors 2 and 17 is opened. A base flange 34 for sealing from the foamed heat insulating material filling space of 2 and 17 is provided at the base, and an opening 30 for accommodating the shade 45 is formed in the throat portions 23 and 24 of the doors 2 and 17. The inner surfaces 23a and 24a of the throat portions 23 and 24 facing the openings 30 are brought into contact with the back surface portions 29a facing the front side portions of the light source attachment 29, and the peripheral edges of the openings 30 of the throat portions 23 and 24 are brought into contact with each other. The outer surface 32a of the tip flange 32 of the light source fixture 29 is brought into contact with the inner surfaces 23b and 24b of the outer portion.

これにより、扉2,17の発泡断熱材16,21の充填圧に対して、光源取付具29の背面部29aと光源取付具29の先部フランジ32の外面32aとがそれぞれと当接相手部(スロート部23,24の開口部30と対向する内面23a,24a、スロート部23,24の開口部30の周縁部より外方の部分の内面23b,24b)に当接して、光源取付具29がスロート部23,24内に定着され、すなわち、発泡断熱材16,21の充填圧による光源取付具29の逃げのない状態で、コネクタハウジング35のケース部37の後面によりシール44が光源取付具29の基部フランジ34の前面に圧せられるので、発泡断熱材16,21の充填時における光源取付具29の内部、すなわちLED37が位置する部分の密閉がより確実にでき、LED37による照明効果を発泡断熱材16,21で損なうことのないようにできる。 As a result, the back surface 29a of the light source fixture 29 and the outer surface 32a of the front flange 32 of the light source fixture 29 come into contact with each other with respect to the filling pressure of the foamed heat insulating materials 16 and 21 of the doors 2 and 17, respectively. (Inner surfaces 23a, 24a facing the openings 30 of the throat portions 23, 24, inner surfaces 23b, 24b of the portion outside the peripheral edge of the openings 30 of the throat portions 23, 24), and the light source fixture 29 Is fixed in the throat portions 23 and 24, that is, the seal 44 is attached to the light source attachment by the rear surface of the case portion 37 of the connector housing 35 in a state where the light source attachment 29 does not escape due to the filling pressure of the foam insulating materials 16 and 21. Since it is pressed against the front surface of the base flange 34 of 29, the inside of the light source fixture 29 when the foamed heat insulating materials 16 and 21 are filled, that is, the portion where the LED 37 is located can be more reliably sealed, and the lighting effect of the LED 37 is foamed. The heat insulating materials 16 and 21 can be used so as not to damage the material.

更に、上記構成の冷蔵庫においては、扉2,17のスロート部23,24に、上記シェード45を収容する開口部30を型抜きにより形成するための段差Dを設けている。これにより、その開口部30の形成が容易にできる。ことに、扉2,17のスロート部23,24の外側近傍においては、内板14,19にガスケット取付け用の溝48を形成しており、この溝48は、ガスケットの抜止めをする突部48bをガスケット差込み用の開口部48aの両側に有しているものの、前後(図6では上下)に強制的に離型することによって形成される。 Further, in the refrigerator having the above configuration, the throat portions 23 and 24 of the doors 2 and 17 are provided with a step D for forming an opening 30 for accommodating the shade 45 by die cutting. As a result, the opening 30 can be easily formed. In particular, in the vicinity of the outer side of the throat portions 23 and 24 of the doors 2 and 17, a groove 48 for attaching a gasket is formed in the inner plates 14 and 19, and this groove 48 is a protrusion for retaining the gasket. Although 48b is provided on both sides of the gasket insertion opening 48a, it is formed by forcibly releasing the mold in the front-rear direction (upper and lower in FIG. 6).

それに対して、上記スロート部23,24の開口部30は溝48の開口部48aとは交差(特には直交)する左右方向の向きに設けており、この開口部30をその向きどおりの型抜き(離型)によって形成しようとすると、上記内板14,19のガスケット取付け用の溝48形成の離型構造と干渉してしまい、形成できなくなるか、もしくはそれらの型構造がきわめて複雑で高価なものとなる。 On the other hand, the openings 30 of the throat portions 23 and 24 are provided in the left-right direction intersecting (particularly orthogonal to) the openings 48a of the grooves 48, and the openings 30 are die-cut according to the orientation. If it is attempted to be formed by (release), it interferes with the release structure of the groove 48 for mounting the gaskets of the inner plates 14 and 19, and cannot be formed, or those mold structures are extremely complicated and expensive. It becomes a thing.

しかし、上記構成の冷蔵庫においては、扉2,17のスロート部23,24に開口部30を型抜きにより形成するための段差Dを設けており、それによって、開口部30を内板14,19のガスケット取付け用の溝48と同じ前後の離型によって形成できるので、開口部30形成が前後にのみ離型する単純な型で容易に、且つ安価にできる。 However, in the refrigerator having the above configuration, the throat portions 23 and 24 of the doors 2 and 17 are provided with a step D for forming the opening 30 by die cutting, whereby the opening 30 is formed on the inner plates 14 and 19. Since it can be formed by the same front and rear mold release as the gasket mounting groove 48 of the above, the opening 30 can be easily and inexpensively formed with a simple mold that can be released only in the front and rear.

なお、この場合、扉2,17のスロート部23,24には、段差Dに代えて、それと同程度の勾配を有する傾斜を設けるようにしても良い。
加えて、上記構成の冷蔵庫においては、扉2,17のスロート部23,24に前記シェード45を表面部とほゞ面一に設けている。これにより、シェード45が扉2,17のスロート部23,24より外方にほとんど出っ張らず、冷気の漏れ防止とポケット部25,26の横幅寸法確保のために必要最小限に抑えられる、扉2,17のスロート部23,24と庫本体1の内側面部との間の間隙寸法内にシェード45を収めることができて、その扉2,17のスロート部23,24と庫本体1の内側面部との間の間隙寸法を大きくする必要をなくし得、冷気の漏れ防止とポケット部25,26の横幅寸法の確保に支障を来たさないようにできる。
In this case, the throat portions 23 and 24 of the doors 2 and 17 may be provided with an inclination having a slope similar to that of the step D instead of the step D.
In addition, in the refrigerator having the above configuration, the shade 45 is provided on the throat portions 23 and 24 of the doors 2 and 17 so as to be almost flush with the surface portion. As a result, the shade 45 hardly protrudes outward from the throat portions 23 and 24 of the doors 2 and 17, and is suppressed to the minimum necessary to prevent leakage of cold air and secure the width dimension of the pocket portions 25 and 26. The shade 45 can be accommodated within the gap between the throat portions 23, 24 of the doors 2, 17 and the inner side surface portion of the storage body 1, and the throat portions 23, 24 of the doors 2, 17 and the inner side surface portion of the storage body 1 can be accommodated. It is possible to eliminate the need to increase the size of the gap between the pockets and the pockets, so as not to hinder the prevention of leakage of cold air and the securing of the width of the pockets 25 and 26.

以上に対して、図7及び図8は第2及び第3の実施形態を示すもので、それぞれ、第1の実施形態と同一の部分には同一の符号を付して説明を省略し、異なる部分についてのみ述べる。 With respect to the above, FIGS. 7 and 8 show the second and third embodiments, and the same parts as those of the first embodiment are designated by the same reference numerals and the description thereof is omitted. Only the part will be described.

[第2の実施形態]
図7に示す第2の実施形態においては、前述の光源固定具29に代えて、保持爪51を開放先端部に有する光源固定具52を用い、その保持爪51に、LED37を実装した回路基板38を係合させて装着している。又、このものの場合、扉2,17スロート部23,24も先端部が外側の側面部から内側の側面部にかけて開放しており、その開放部に、前述のシェード45に代わるシェード53を装着してスロート部23,24の開放先端部を閉塞している。このようにして、このものの場合には、シェード53は、扉2,17のスロート部23,24の先端部に設けているのである。
[Second Embodiment]
In the second embodiment shown in FIG. 7, a light source fixture 52 having a holding claw 51 at the open tip is used instead of the light source fixture 29 described above, and a circuit board in which the LED 37 is mounted on the holding claw 51. 38 is engaged and attached. Further, in the case of this case, the tips of the doors 2, 17 throat portions 23, 24 are also open from the outer side surface portion to the inner side surface portion, and a shade 53 instead of the above-mentioned shade 45 is attached to the open portion. The open tips of the throat portions 23 and 24 are closed. In this way, in this case, the shade 53 is provided at the tip ends of the throat portions 23 and 24 of the doors 2 and 17.

このようにすることにより、照明装置27,28のLED37からシェード53を透して前記冷蔵室6に照射される光の照射範囲をより大きくすることができるものであり、特に、扉2,17を微小角度開放させたときにも冷蔵室6を照射しやすくできる効果がある。 By doing so, the irradiation range of the light radiated to the refrigerating chamber 6 through the shade 53 from the LEDs 37 of the lighting devices 27 and 28 can be further increased, and in particular, the doors 2 and 17 can be increased. There is an effect that the refrigerating chamber 6 can be easily irradiated even when the refrigerator is opened at a minute angle.

[第3の実施形態]
図8に示す第3の実施形態においては、LED(光源)37を、光を広角に照射する広角仕様のものとしている。具体的には、LED37からシェード45を透して冷蔵室6に照射される光の照射範囲L3,L4を、前述の照射範囲L1,L2に代えて、それよりも大きな例えば90度角のものとしている。
[Third Embodiment]
In the third embodiment shown in FIG. 8, the LED (light source) 37 has a wide-angle specification that irradiates light at a wide angle. Specifically, the irradiation ranges L 3 and L 4 of the light emitted from the LED 37 through the shade 45 to the refrigerating chamber 6 are replaced with the above-mentioned irradiation ranges L 1 and L 2, and are larger than that, for example, 90. It is supposed to be a degree.

このようにすることにより、光の照射範囲が小さいものでは、扉2,17の開放角度の変化に伴って光の照射範囲が変移するのが使用者に分かりやすく、使い勝手が良くないところ、その光の照射範囲が変移するのが使用者に分かりにくくなり、使い勝手を良くすることができる。 By doing so, when the light irradiation range is small, it is easy for the user to understand that the light irradiation range changes as the opening angles of the doors 2 and 17 change, which is not convenient. It becomes difficult for the user to understand that the light irradiation range changes, and the usability can be improved.
