Description of the invention: [Technical field to which the invention pertains] The present invention relates to a refrigerator. In particular, when lighting the threshold of the storage compartment of the refrigerator, the room and the like are illuminated. [Prior Art] In the past, the use of a white heat bulb in a lighting device installed in a storage compartment of a refrigerator and a door pocket for storage is a major mainstream. In recent years, a light-emitting diode has been proposed which contributes to saving power consumption (after Called LED). However, compared with the white heat bulb, the LED has a small light-emitting area and a strong directivity, so the illumination range is also narrow. In order to effectively illuminate a wide storage compartment, it is necessary to provide a larger number of leds than the white heat bulbs. To ensure that the illumination room has the same illumination as the white heat bulb, the manufacturing cost tends to increase. Therefore, in order to compensate for the shortcomings such as a small light-emitting area and a strong directivity, an invention has been proposed, that is, the illumination device using the device (10) is directed to the rear side of the storage chamber and assembled in an inclined state (see Patent Document 1 for an example). Further, an invention has been proposed in which the illuminating device is assembled in a state in which the direction of the optical axis of the LED is incident on the front side of the shelf of the storage compartment = the front part of the intermediate irradiation shelf (for example, refer to Patent Document 2) ). [Patent Document 1] Patent No. 4405803 [Patent Document 2] Patent No. 4 054 365 [Summary of the Invention] 2148-10249-PF 5 1375779 [Problems to be Solved by the Invention] / For example, in the above-mentioned patent document! The led is directed toward the rear side of the storage compartment and is made to emit light. Therefore, the light of the LED can be concentrated in the storage compartment. On the other hand, the illumination on the front side (the side of the threshold) of the storage compartment becomes less, so that an effective illumination setting is generated. In the refrigerator of the above-mentioned Patent Document 2, the light is concentrated on the front portion of the rack. On the other hand, the illuminance on the rear side of the storage compartment is reduced, and the rear side of the storage compartment is darkened. On the other hand, the light that is the most out of the 氺 氺 火 火 火 火 火 火 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 尤 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 In order to solve the problem of the above-mentioned problems, the present invention has an object of obtaining an ice-"-using a lighting device having a small amount of heat generation and a small power consumption to form a storage room." The ED light illuminates the entire storage room. [Means for Solving the Problem] The refrigerator of the present invention includes a storage compartment that is open to the outside space through an openable and closable door and has a space for accommodating the storage space, and a plurality of A shelf that partitions the plurality of storage spaces in the storage compartment from the storage compartment and the shelf that is closer to the side wall of the storage compartment than the shelf in the upper and lower directions is arranged in the upper and lower directions for illumination. An illumination device provided by the plurality of light-emitting diodes of the storage chamber, wherein an angle between the optical axis of the light-emitting diode and the side wall is greater than 6 degrees on a plane parallel to the rack, and the light is emitted Light of the diode 2148-1024 9^pp 6 1375779 The light in the axial direction is directly incident on the above-mentioned rack, facing the above-mentioned plurality of light-emitting diodes of the above illumination device. • [Effect of the Invention] According to the present invention, an illumination device having a plurality of LEDs is provided at a position on the left and right sides of the storage compartment of the refrigerator closer to the front than the rack, so that the optical axis and the side of the light emitted by each LED are provided. The angle of the clip is greater than 6 degrees, and the light in the direction of the optical axis is not directly incident on the shelf. Therefore, the light in the direction of the optical axis of the LED does not directly face the leading edge of the rack, which can cause the user to dazzle. Reduced and ensured high visibility inside the storage compartment. Moreover, the direction of the LED of the device does not face the rear side of the storage compartment, so that the door sill of the front side sill can be irradiated. I. BEST MODE FOR CARRYING OUT THE INVENTION The first embodiment is a schematic side cross-sectional view of the ice phase 1 of the first embodiment of the first and third classes. in
本實施型態中，以具有用來收納 π只了職(食品等）之冷藏室 2、切換至3、蔬菜室4、冷束室5算滿奴加 斤Λ b4複數個貯藏室來構成冰 相1。又，具有轉軸式門扉6(以下 為門扉6)、拉出式門扉 7’進仃各貯藏室内部與外部之間的 工間開放和遮蚁。以下 將說明具有門扉6、置物架8等之冷 不受此限定。 7藏至2,然而本發明本身 在此，如第1圖所示，冰箱丨之 ^ , $狀為約略長方體，但 一側的面作為前 面。又，將第1圖中 根據冰相1之設置方向，將具有門扉之這 一 面，將相對於前面之後側的那面作為後 2148-10249-PF 7 叫5779 以下將LED9之發光之光線方向作為與置物架8平行之平 •面之方向來進行說明（並未規範上下方向之光線）。 第4圖為從上面來看冰箱2的圖。如前所述，門扉6設置 於冷藏室2之前面。在本實施型態之冰箱丨中，冷藏室2之前 面具有分別以轉轴（未圖示）與冰箱丨之本體連結且藉由所 謂雙門式開閉使冷藏室2之空間對外部開放或受到遮蔽的 門扉6A及6B。在此，將面對冰箱上之右側之門扉作為右門 • 6A，將左側之門扉作為左門6B(當沒有需要特別區分時，僅 說明門扉6 )。又，門扉6於内侧具有食品收納用之門套丨丄。 又，照明裝置10之構造為，在構成電子電路之印刷基板^ 6 上附加複數個LED9。不過，印刷基板16這部分不在冷藏室2 内部露出。在本實施型態中，如第4圖所示，使LED9之光軸 相對於内側壁13所夾之角度0大於6〇度，再者，使^卯朝 向LED9之光軸12之方向之光線不直接入射至置物架8(尤其 是前緣部分）之方向，如此組裝照明裝置丨〇。藉由使角度0 • 大於60度’可在照射整個置物架8時，進行不會產生不均現 象且平衡良好之照射。在此，在使角度0大於6〇度之狀態 下使光軸12之方向之光線入射至置物架8的情況下，若沒有 反射光使使用者產生目眩等狀況，基本上宜優先採用光軸 1.2之方向之光線不直接入射至置物架8之方向。又，角度θ 之上限並未跟定’不過’由於主要是照明冷藏室2之内部， 所以，角度0在90度以下。 第5圖習知之.冰箱的俯視圖。在習和之冰箱中，為使[Ερ 相對於内側壁之角度為60度以下且使LED之光轴方向之光 2148-10249-PF 9 1375779 線朝向I物架8之方向，光線傾向於集中照射在冷藏室2之 後侧。因此，雖然可照明冷藏室2之内部，但L£D9之光轴12 之方向之光線直接入射至置物架8，所以，置物架8前緣所 產生之反射光強烈入射至冰箱使用者之眼睛產生目眩。 相對於此，在本實施型態之冰箱〗中，LEDg在光轴12之方向 所發出之光線並未直接入射至置物架8,所以，可大幅減輕 反射所產生之目眩。 # 又’如剛所述’作為照明裝置1 〇之光源的LED9的指向 陡強，強烈照射出以光軸丨2為中心之有效照射範圍α中之 光線。在此，若使LED9之光軸12之方向相對於内側壁13所 夹之角度0產生變化，有效照射範園α也會連動而跟著變 化。如第5圖所示，在習知之冰箱中，使LED9之光轴12之方 向相對於内侧壁13所夾之角度0在6〇度以下，集中照射冷 藏室2内部，所以，所開啟之門扉6不被包含在LED9之有效 照射範圍α之中。因此，對於設於門扉6之内側的門套〗ι， _ LED9之光線之照射變得較少、較暗。門套11為對於收納或 取出飲料、小東西等物品非常便利的收納空間，所以，若 考量使用者之便利’宜具有可照明門套丨丨之效果.。 因此’在本實施型態之冰箱1中，使LED9之光軸12相對 於内側壁13所夾之角度θ為大於60度的角度，所以，可將 門套11包含在有效照射範圍α (之延長線上）^於是，LED9 可在照射冷藏室2内部的同時，也照明門套11。 . 如上所述，根據第1實施型態，當將因發熱量少且具有 低消耗電力而得以省能之LED9使用於照明時，在冰箱i之冷 2148-10249-PF 10 1375779 • 藏室2之内部之左右内側壁13比置物架8還要前側（門扉6那 ，侧）的位置上，設置沿著上下方向排列複數個LEDg的照明裝 置10，使各LED9所發出之光線之光軸12和内側壁13所夹之 .角度大於60度，又’光轴12之方向之光線不直接入射至置 物架8,所以，可使LED9之光軸12之方向之光線不直接對著 置物架8之前緣而減輕使用者之目眩情況，並可確保冷藏室 2之内部之高辨識性。又，並未使照明裝置〗〇於冷藏室之之 φ 内部後方傾斜而設置，所以，亦可照射冷藏室2之前側亦即 叹置於門扉6之門套11。於是，不需要設置用於門套丨丨之照 明的裝置，可有助於降低成本和省能。 第2實施型態， 第6圖為從冰箱2之上面那側來看第2實施型態中之照 明裝置1 0和燈蓋（燈罩）丨5之間之.關係的圖。在本實施型態 中也一樣，照明裝置丨〇之構造為在印刷基板丨6上附加複數 個LED9。在本實施型態中，於内側壁13上比置物架8前緣還 • 要前側（靠近門扉6)之位置形成凹部1 3A，在凹部13A内設置 照明裝置10。然後，以燈蓋15覆蓋凹部13A。不過，本發明 不受此限疋’亦可在不形成凹部13A之狀態下以燈蓋15來覆 蓋。 燈蓋15在至少可見光之範圍内以透明材料之樹脂成 型’具有用來使照明裝置丨〇貼合而固定為_體的爪部i 4 等。不過，照明裝置丨0之固定並不限定只能採用爪部丨4等 之貼合等。又’燈蓋丨5在其中一部分具有用來使入射至光 折射的透鏡部1 5A。為了將入射至光導引至冷藏室2之後 2148-10249-PF 11 5779 側，以與内侧壁13之間夾有角度之狀態配置透鏡部l5A。 在上述第1實施型態中，規範了 LED9相對於設置照明裝 置10之位置的方向，藉此，減輕使置物架8所產生之反射光 帶來之目眩，同時進行門套21之照明。不過，LED9之有效 照射範圍α於置物架8所佔之比率變小，所以，無法充分照 明冷藏室2之後側的疑慮產生。為了補償冷藏室2之内部之 亮度減少，宜作為光源之LED9之數量，不過，這樣會有成 本提高的缺點。因此，在本實施型態中，藉由使用具有透 鏡部15A之燈蓋15，進一步得到整個冷藏室2之亮度之改 善，以低廉之結構實現冷藏室2等之照明。 第7圖表示使用燈蓋15時之LED9之光線之前進方向的 變化。如第7(a)圖所示，在本實施型態之燈蓋”中入射 至透鏡部15A之部分的光線在透鏡部15A内折射，在冷藏室2 之後側之有效照射範圍α内照射無法覆蓋之範圍。另一方 面，入射至透鏡部15 Α以外之部分的光線雖然隨著入射角進 行些微之折射，但幾乎以直線前進之狀態照射門套1}。相 對於此，若不附加燈蓋丨5之狀態或不具有透鏡部^ Μ之平坦 燈蓋17,如第7(b)圖所示，LED以簡易光軸18之狀態直線前 進。 燈蓋15所折射之LED9之光線之一部分朝向置物架8之 方向。因此，光線直接入射至置物架8，恐怕會導致目眩。 不過，藉由衰減穿透燈蓋15時之光度或光折射等之方向隨 著樹脂成型之燈蓋15之正面及背面之粗糙表面而不同而導 致之分散作用，相較於LED9之簡易光軸18直接入射至置物 2148-10249-PF 12 1375779 架8之情況，可大幅減低目眩。 第8圖表示LED9和燈蓋15的位置關係。尤其在本實施型In the present embodiment, the ice storage compartment 2, which is used for accommodating π-only (food, etc.) 2, is switched to 3, the vegetable compartment 4, and the cold-collecting chamber 5 is counted as a storage compartment of the slave b. Phase 1. Further, the hinge type sill 6 (hereinafter referred to as the sill 6) and the pull-out type sill 7' are opened between the storage compartments and the outside, and the ants are opened. The cooling with the sill 6, the rack 8, and the like will not be described below. 7 is hidden to 2, however, the invention itself is here, as shown in Fig. 1, the refrigerator is in the shape of a roughly rectangular parallelepiped, but the side on one side is the front. Further, in the first drawing, according to the direction in which the ice phase 1 is disposed, the surface having the threshold is used, and the surface on the front side is referred to as the rear 2148-10249-PF 7 and 5779 or less. The direction of the flat surface parallel to the rack 8 is explained (the light in the up and down direction is not specified). Fig. 4 is a view of the refrigerator 2 as seen from above. As previously mentioned, the sill 6 is disposed in front of the refrigerating compartment 2. In the refrigerator of the present embodiment, the front surface of the refrigerating compartment 2 is connected to the main body of the refrigerator 以 by a rotating shaft (not shown), and the space of the refrigerating compartment 2 is opened or received to the outside by so-called double-door opening and closing. Covered thresholds 6A and 6B. Here, the threshold on the right side of the refrigerator is used as the right door • 6A, and the threshold on the left side is used as the left door 6B (only when the door is not required to be distinguished, only the threshold 6 is explained). Further, the sill 6 has a door pocket for food storage on the inner side. Further, the illuminating device 10 is configured such that a plurality of LEDs 9 are added to the printed circuit board 6 constituting the electronic circuit. However, this portion of the printed substrate 16 is not exposed inside the refrigerating chamber 2. In the present embodiment, as shown in FIG. 4, the angle 0 of the optical axis of the LED 9 with respect to the inner side wall 13 is greater than 6 degrees, and further, the light of the direction toward the optical axis 12 of the LED 9 is made. The illumination device is assembled in such a manner that it is not directly incident on the direction of the rack 8 (especially the leading edge portion). By making the angle 0 • greater than 60 degrees, it is possible to perform illumination without unevenness and good balance when the entire rack 8 is irradiated. Here, when the light in the direction of the optical axis 12 is incident on the rack 8 in a state where the angle 0 is greater than 6 degrees, if the reflected light does not cause the user to be dazzled, etc., it is preferable to preferably use the optical axis. The light in the direction of 1.2 is not directly incident on the direction of the rack 8. Further, the upper limit of the angle θ is not set to 'but' because the inside of the refrigerating compartment 2 is mainly illuminated, the angle 0 is 90 degrees or less. Figure 5 is a conventional view of the refrigerator. In the refrigerator of the present, the light tends to concentrate in order to make the angle of [Ερ with respect to the inner side wall 60 degrees or less and the light of the optical axis direction of the LED 2148-10249-PF 9 1375779 line toward the object rack 8 Irradiation is performed on the rear side of the refrigerating compartment 2. Therefore, although the inside of the refrigerating compartment 2 can be illuminated, the light of the direction of the optical axis 12 of L£D9 is directly incident on the rack 8, so that the reflected light generated by the leading edge of the rack 8 is strongly incident on the eyes of the refrigerator user. Dizzy. On the other hand, in the refrigerator of the present embodiment, the light emitted by the LEDg in the direction of the optical axis 12 is not directly incident on the rack 8, so that the glare caused by the reflection can be greatly reduced. #又' As just as described above, the LED 9 as the light source of the illumination device 1 is sharply pointed, and strongly illuminates the light in the effective illumination range α centered on the optical axis 丨2. Here, if the direction of the optical axis 12 of the LED 9 is changed with respect to the angle 0 sandwiched by the inner side wall 13, the effective illumination range α is also changed in conjunction with the change. As shown in FIG. 5, in the conventional refrigerator, the angle of the optical axis 12 of the LED 9 with respect to the inner side wall 13 is less than 6 degrees, and the inside of the refrigerating chamber 2 is concentratedly irradiated. Therefore, the threshold is opened. 6 is not included in the effective illumination range α of the LED 9. Therefore, the irradiation of the light of the door cover 〗 〖, LED 9 provided on the inner side of the sill 6 becomes less and darker. The door cover 11 is a storage space that is very convenient for storing or taking out items such as drinks and small things. Therefore, it is preferable to have an effect of illuminating the door cover if the convenience of the user is considered. Therefore, in the refrigerator 1 of the present embodiment, the angle θ of the optical axis 12 of the LED 9 with respect to the inner side wall 13 is an angle greater than 60 degrees, so that the door cover 11 can be included in the effective irradiation range α (extended On the line, the LED 9 can also illuminate the door cover 11 while illuminating the inside of the refrigerating compartment 2. As described above, according to the first embodiment, when the LED 9 which is energy-saving due to low heat generation and low power consumption is used for illumination, the refrigerator 2i is cold 2148-10249-PF 10 1375779 • the storage room 2 The left and right inner side walls 13 of the inner side are disposed on the front side (the side of the sill 6 side) of the rack 8, and the illuminating device 10 in which a plurality of LEDgs are arranged in the vertical direction is provided so that the optical axis 12 of the light emitted from each of the LEDs 9 is provided. The angle between the inner side wall 13 and the inner side wall 13 is greater than 60 degrees, and the light in the direction of the optical axis 12 is not directly incident on the rack 8, so that the light in the direction of the optical axis 12 of the LED 9 is not directly opposed to the rack 8. The front edge reduces the dizziness of the user and ensures high visibility inside the refrigerating compartment 2. Further, since the illuminating device is not disposed so as to be tilted inside the inside of the refrigerating chamber φ, it is possible to illuminate the door cover 11 which is placed on the front side of the refrigerating chamber 2, that is, the sill. Thus, there is no need to provide a means for illuminating the door pocket, which can help to reduce cost and energy. In the second embodiment, Fig. 6 is a view showing the relationship between the illumination device 10 and the lamp cover (lamp cover) 5 in the second embodiment as seen from the upper side of the refrigerator 2. Also in the present embodiment, the illumination device is configured to add a plurality of LEDs 9 to the printed substrate 丨6. In the present embodiment, the concave portion 13A is formed on the inner side wall 13 from the leading edge of the rack 8 at the front side (near the sill 6), and the illuminating device 10 is provided in the concave portion 13A. Then, the recess 13A is covered with the lamp cover 15. However, the present invention is not limited to this, and the cover 15 may be covered without forming the recess 13A. The lamp cover 15 is formed of a resin of a transparent material in a range of at least visible light, and has a claw portion i 4 or the like for fixing the illuminating device to the body. However, the fixing of the illuminating device 丨0 is not limited to the fitting of the claw 丨4 or the like. Further, the lamp cover 5 has a lens portion 15A for refracting incident light thereto. In order to guide the incident light to the side 2148-10249-PF 11 5779 after the refrigerating compartment 2, the lens portion 15A is disposed in an angled angle with the inner side wall 13. In the first embodiment described above, the direction of the position of the LED 9 with respect to the position where the illumination device 10 is disposed is specified, whereby the glare caused by the reflected light generated by the rack 8 is reduced, and the door cover 21 is illuminated. However, since the ratio of the effective irradiation range α of the LED 9 to the shelf 8 is small, the occurrence of doubt on the rear side of the refrigerator compartment 2 cannot be sufficiently illuminated. In order to compensate for the decrease in the brightness of the interior of the refrigerating compartment 2, it is preferable to use the number of LEDs 9 as a light source. However, there is a disadvantage that the cost is increased. Therefore, in the present embodiment, by using the lamp cover 15 having the lens portion 15A, the brightness of the entire refrigerating chamber 2 is further improved, and the illumination of the refrigerating chamber 2 or the like is realized with an inexpensive structure. Fig. 7 shows the change in the forward direction of the light of the LED 9 when the lamp cover 15 is used. As shown in Fig. 7(a), the light incident on the portion of the lens portion 15A in the lamp cover of the present embodiment is refracted in the lens portion 15A, and the irradiation in the effective irradiation range α on the rear side of the refrigerator compartment 2 cannot be performed. On the other hand, the light incident on the portion other than the lens portion 15 is slightly refracted with the incident angle, but the door cover 1 is irradiated almost in a straight line. In contrast, the lamp is not attached. In the state of the cover 5 or the flat lamp cover 17 having no lens portion, as shown in Fig. 7(b), the LED advances linearly in the state of the simple optical axis 18. One part of the light of the LED 9 refracted by the lamp cover 15 The direction of the rack 8 is directed. Therefore, the light is directly incident on the rack 8, which may cause dizziness. However, the lamp cover 15 is formed with the resin by attenuating the direction of the illuminance or the light refraction of the lamp cover 15 The dispersing effect caused by the different rough surfaces on the front and back sides can greatly reduce the dizziness compared to the case where the simple optical axis 18 of the LED 9 is directly incident on the holder 2148-10249-PF 12 1375779. Figure 8 shows the LED 9 and The positional relationship of the lamp cover 15. In the present embodiment type
態中，該圖可作為光轴12之方向之光線入射至透鏡部15A 並被導引至冷藏室2之後側的LED 9和燈蓋15的位置關係。當 採用利用LED9之光折射的燈盖15時’ LED9之有效時射範圍 α和燈蓋15之前後方向之位置關係非常重要。第g(a)圖表 示LED9和燈蓋15取得適當位置關係的情況。當在取得適當 位置關係的情況下’ LED9之光軸12之方向之光線入射至燈 蓋15之透鏡部15A’冷藏室2之後侧被導入強光。另一方面， 在第8(b)圖所示之情況下，光線不入射至透鏡部15A，幾乎 直線進行，原來應該有效照射置冷藏室2之内部的光線變得 無用。 第9圖表不燈蓋1 5之形狀和光折射之間的關係。可使 LED9之光線折射到何種程度是視透鏡部15A之規格而定。在 以第9(a)圖所示之燈蓋15為基準的情況下，為了簡單增大In the state, the light which is incident as the direction of the optical axis 12 is incident on the lens portion 15A and guided to the positional relationship of the LED 9 and the lamp cover 15 on the rear side of the refrigerating chamber 2. When the lamp cover 15 refracted by the light of the LED 9 is used, the positional relationship between the effective time range α of the LED 9 and the front and rear directions of the lamp cover 15 is very important. The g-th diagram (a) shows the case where the LED 9 and the lamp cover 15 have an appropriate positional relationship. When the appropriate positional relationship is obtained, the light in the direction of the optical axis 12 of the LED 9 is incident on the lens portion 15A' of the lamp cover 15 and the rear side of the refrigerating chamber 2 is introduced with strong light. On the other hand, in the case shown in Fig. 8(b), the light is not incident on the lens portion 15A, and the light is almost straight, and the light which should be effectively irradiated inside the refrigerator compartment 2 becomes useless. The ninth graph does not relate the relationship between the shape of the lamp cover 15 and the light refraction. The degree to which the light of the LED 9 can be refracted depends on the specifications of the view lens portion 15A. In the case of the lamp cover 15 shown in Fig. 9(a), for the sake of simplicity
折射角，如第9(b)圖所示，宜增厚燈蓋15之透鏡部15A(使 光線折射之部分）中之樹脂之厚度。不過，一般來說，若過 度增厚樹脂之厚度，容易產生收縮等現象，難以形成所要 之形狀’所以，樹脂之厚度宜控制在4丽左右。因此，為了 宜使透鏡部15A之剖面為鋸齒 形成複數個由第9(b)圖之厚 9(d)圖所示，斜面之斜率越 ，光線之入射角越小，折射. 面之傾斜角度變化，所以， 避免收縮，如第9(c)圖所示， 狀（使其具有複數個三角形）， 層所形成之斜面。此時，如第 大’在與斜面之斜率的關係中 越大。如此，折射角也隨著斜The angle of refraction, as shown in Fig. 9(b), is to thicken the thickness of the resin in the lens portion 15A of the lamp cover 15 (the portion where the light is refracted). However, in general, if the thickness of the resin is excessively thickened, shrinkage or the like is likely to occur, and it is difficult to form a desired shape. Therefore, the thickness of the resin should be controlled to about 4 Å. Therefore, in order to make the cross section of the lens portion 15A into a plurality of saw teeth, as shown by the thickness 9 (d) of the 9th (b) diagram, the slope of the slope is smaller, and the incident angle of the light is smaller, and the angle of inclination of the surface is refraction. Change, so, avoid shrinkage, as shown in Figure 9(c), the shape (making it have a plurality of triangles), the slope formed by the layer. At this time, the larger one is larger in the relationship with the slope of the slope. Thus, the angle of refraction is also skewed

In addition, the East 74 teaches _1_ stupidity, and in order to form part of the inner wall of the refrigerating compartment 2, it is also necessary to take into consideration the characteristics of the invading surnames such as oil, food juice, and the like. Fig. 11 shows a method of assembling the lighting device 10 to the refrigerator J. As shown in Fig. 5(a), there is a method in which the claw portion 1.4 is placed in the concave portion 13A and the illumination device is attached to the claw portion 14 to be directly assembled to the body of the refrigerator L, as shown in the nth (b) figure. As shown, there is also a method of assembling the lighting device 10 to the lamp cover 15 and then assembling it to the body of the refrigerator. When the lighting device 10 is directly assembled to the recess 13A, the LED 9 and the lamp cover are changed due to the assembly. The positional relationship of 15 may cause a large amount of offset so that the light of the effective illumination range α of the LED 9 is not incident on the lens portion 15Α with good efficiency. On the other hand, when the known device 10 is pre-assembled on the lamp cover 〖5 The positional relationship between the LED 9 and the lamp cover 15 does not generate a large amount of offset. Therefore, the light of the LED 92 can be incident on the lens portion 15A' by a predetermined positional relationship, and the lamp cover 15 can be inside the refrigerating chamber 2 by the lamp cover 15. The maximum limit is taken out. Therefore, the lighting device 10 is finally installed in the refrigerator 1 after being pre-assembled in the lamp cover 15. Otherwise, when the lighting device is directly assembled, 2148-10249-pf 14 1375779 When the inner side wall 13 is 3, it is necessary to properly perform the lighting device 1 The configuration of the alignment of 0 and the lamp cover 15 is not offset. As described above, the productivity at the time of producing the refrigerator 1 can be improved by assembly. Fig. 12 is a view showing an example of the shape of the concave portion 13 of the inner side wall 13. 12(&) As shown in the figure, as the direction of the LEDs 9 is arranged, a portion of the light may be incident on the recess 13A of the inner side wall 13 without being incident on the lamp cover 15. One of the rays incident on the recess 13 is further toward the other of the recess 13A. The position continues to advance, and the light sometimes does not come out from the outer side of the lamp cover 15. Therefore, as shown in Fig. 1.2(b), the light emitted by the LED 9 is reflected in the concave portion 13A, so that the reflected light is not further incident on the concave portion. The other position of 13A is designed to form the angle of the concave surface of the concave portion 13a, whereby the light emitted from the LED 9 can be more effectively guided to the outside of the lamp cover 15. In particular, most of the light incident on the front side of the concave portion 13A is large. It becomes completely useless, so that the angle of the concave portion i3a is important in order to prevent the light from entering the concave portion 13A from the outer side of the lamp cover 15, and the door cover 11 including the sill 6 on the front side of the refrigerating chamber 2 is not incident. Above concave 1 3 A and the light coming out from the outer side of the lamp cover 1 5 illuminates the door cover 11. If the recessed portion A 3A of the inner side wall 丨 3 has an angle in this way, the useless light is guided to the lamp cover. On the outer side, effective irradiation including the door cover π provided on the entire surface of the refrigerating chamber 2 can be realized. Further, as described above, in the range outside the effective irradiation range α of the LED 9, the light is not emitted at all, even if the concave portion is made i 3Α is inclined, and part of the light still faces the concave portion 13. Therefore, the strategy of guiding the light to the outside of the lamp cover 15 in the concave portion 13 is quite effective. Figure 13 shows the reflection strategy of the recess 13Α. As shown in the 13th (&) diagram, the cold air of 2148-1024 9-PF 15 1375779 directly faces the LED 9, the partition plate 27 can also be cooled by the cold air, and the air around the illumination device ίο is also indirectly cooled, so It can also cool the LED9. The partitioning plate 27 is reinforced with an adhesive tape or the like as occasion demands to prevent the inflow of air and moisture from the blower. As described above, according to the second embodiment, the light beam emitted from the LED 9 is refracted by the lamp cover 15 having the lens portion 15, and the amount of light traveling on the rear side of the refrigerator compartment 2 is increased. Therefore, the first embodiment is implemented. The same type can reduce the dizziness of the refrigerator user and obtain the illumination of the door cover U, and further improve the brightness of the interior of the refrigerating compartment 2. In addition, even if the number of LEDs 9 as a light source is not increased, the improvement in brightness can be achieved with an inexpensive configuration. Further, the illumination of the refrigerator compartment 2 or the like can be adjusted by setting the shape of the lens portion 15A to a desired shape. Further, the lamp cover 15 is provided with the claw portion 14 and the like, and the illuminating device 1 is directly assembled to the lamp cover 15 and then assembled to the recessed portion j 3 A. Therefore, the lamp can be assembled in a predetermined positional relationship. The cover 15 and the LED 9 allow illumination of the interior of the refrigerating compartment 2 in a desired manner. Further, the angle of the concave surface of the concave portion i 3a is designed such that the light of the reflecting concave portion 13A enters the inside of the cold storage chamber 2 through the lamp cover 5, so that the inside of the refrigerator compartment 2 can be efficiently illuminated. At this time, the reflection efficiency can be increased by providing the high reflection element 13C on the front side of the concave portion 1 3A to perform illumination with more efficiency. Further, by using the air outlet Μ and the lamp cover 15 which are used to feed the cold air into the interior of the refrigerating compartment 2, the materials used for the components can be reduced. At this time, the LED 9 can be cooled by the cold air flowing into the air outlet 26, so that the illuminance of the LED 9 can be maintained. Further, by providing the partitioning plate 27 on the lamp cover, "the water can be separated from the water."
2148-1024 9-PF 第3貫施型態. 第16圖表示驅動電路範例。如第16(a)圖所示，白熱燈 泡之亮燈/熄燈透過中繼 繼益19荨機械接點之開關來進行切 換，相對於此，如第 弟16(b)圖所不，LED9之亮燈/熄燈可將 電晶體20等半導體元件當作開關元件來使用，以進行切 、因此相對於白熱燈泡，LED9與發光（驅動）有關之電 Μ和電流非常小。又，用夾你抽 用采切換LED9之亮燈/熄燈的驅動元 件也比較便宜，並可使用壽命較長者。 又，中繼器19由於是機诚垃科 & 仏疋機锇接點’所以切換開關之速度、 使用次數等有一定的限声，τι _ 度不過’電晶體20等半導體元件 可大大地超越此限度而進扞切拟 退仃切換。因此，不僅亮燈/熄燈， 以快速週期反覆亮燈/熄燈 五心阎琛顯不也容易進行。因此， 在具有將L：ED9作為光源之照明| 〜’，，、乃裝置1 〇的冰箱1中，可以照明 裝置1 0之LED9之閃燦次數等來呈現 冰箱.1之自身诊斷異常資訊等指示。 第17圖表示設置於冰箱門靡之操作面板21的範例。在 習知之冰箱上，設置於冰箱之控制裝置1〇。若判斷出冰箱有2148-1024 9-PF 3rd embodiment. Figure 16 shows an example of a drive circuit. As shown in Figure 16(a), the lighting/lighting of the incandescent light bulb is switched by the switch of the relay switch, which is the same as the switch of the mechanical contact, as shown in Figure 16(b), LED9 When the light is turned on/off, the semiconductor element such as the transistor 20 can be used as a switching element to perform cutting. Therefore, the electric current and current associated with the light emission (driving) of the LED 9 are extremely small with respect to the white heat bulb. In addition, it is also cheaper to use the driving element that switches the LED 9 to turn on/off the light, and it can be used for a longer service life. Further, since the repeater 19 is a machine-mounted switch and a pick-up point, the speed and the number of times of use of the switch are limited, and the semiconductor component such as the transistor 20 can be greatly increased. Beyond this limit, we will cut back and switch. Therefore, not only the light is turned on/off, but also the light is turned on/off in a fast cycle. Therefore, in the refrigerator 1 having the illumination of L: ED9 as the light source, the device 1 can be used to display the self-diagnosis abnormality information of the refrigerator, etc. Instructions. Fig. 17 shows an example of the operation panel 21 provided on the door sill of the refrigerator. In the conventional refrigerator, the control device 1 is installed in the refrigerator.

The number 'as shown in the first 7 (b), the number of flashes of the abnormal display LED 23 set on the panel 21 by the μ medium is presented as a stroke, a ro ώ β , and a number display temperature. The sensor side does not correctly detect its own diagnostic abnormality information. Figure 18 shows an example of the flashing of LED 9. In the mode of the abundance, in addition to the sticking _~ 颂 in the operation panel 21 shown in Fig. 17, it is also possible to display the self-diagnosis abnormality information by causing the LED 9 to blink 2148-10249-PF 18 1375779. For example, the flashing of the LED 9 indicates "34", so that the control device 1 blinks for three times and then blinks for 5 seconds, and then blinks four times, thus repeating. Further, similarly, the LED 9 may be blinked in order to notify the state in which the threshold 6 is turned on for a long time. When the (10) 6 is turned on for a long time, the cold air of the refrigerating compartment 2 leaks out and stores α. The coffee is rising and the electricity is being consumed. For example, a flashing display may be used when the threshold is to be closed and the threshold is slightly opened, and foreign matter is lost between the threshold and the body, and the threshold cannot be completely closed. As described above, according to the third embodiment, not only the liquid crystal display unit 22 and the abnormal display LED 23 provided on the operation panel 21 but also have a sufficient brightness "LED9" for illuminating the inside of the refrigerating compartment 2. Since the user displays the abnormality or the like, it is possible to further improve the ability to notify the user of the ice to notify the user of the abnormality and the like. Fourth Embodiment. As described in the third embodiment described above, the switching of the lighting/lighting of the LEDs 9 can be performed by the transistor 20 or the like. Therefore, it is possible to switch the lamp/offer in a shorter cycle: for example, when the lamp/lamp is repeatedly turned on at a frequency of several kilohertz, the person cannot see the flicker due to the illusion, but only sees that the luminosity (brightness) is lowered. Figure 19 shows the relationship between brightness and lighting time. As shown in Fig. 19, the brightness and lighting time are proportional to the unit time (the ratio of the illusion of the week (hereinafter referred to as the load ratio). Thus, by slowly increasing or decreasing the duty ratio, the luminosity can be obtained one by one. The visual effect of the point change. In the third embodiment, the 'diagnostic abnormality information is displayed only by blinking the UD9, but in the present embodiment, the display mode is to adjust the load ratio to make the photometric Variety.
2148-10249-PF 19 1375779 第20圖表示自身診斷異常資訊和負載比之調整之間的 關係。例如’在僅使LED9閃爍的情況下，亮燈時和熄燈時 之亮度變化劇烈，所以，有可能會驚嚇到冰箱使用者。不 過’如第20圖所示’並不完全熄燈，而是慢慢增減光度， 使壳燈樣式產生變化，如此，便不會嚇到使用者，可對其 通報異常等狀況。 又’以上提出藉由負載比之調整所產生之亮度之調整 來顯示自身#斷異常的範例，另外亦有可根據冰箱使用者 之喜好選擇藉由負載比之調整所產生之LED9光度之調整的 功此可使用。從第17圖中之操作面板21進行照明裝置之 冗度之調整指不，冰箱1之使用者可任意設定L.ED9之光度。 例如’在周圍較亮之場所使用冰箱！時外部之光線入射至 V藏至2内。卩，不那麼需要所產生之光線，所以降低 刪所發出之光度準位來使用。又如，當在整理冷藏室之 室内之貯藏品等需要照明冷藏室2内部時，若提高光度準 位’可期待進一步降低消耗電力的效果。 如上所述，根據第4實施型態，當使LED9發光時，調整 負載比’不使其閃燦，而是增減LED9之光度，藉此，可在 不嚇到使用者的情況下，對其通報異常等狀況。又，使用 者可進^丁設定變争望 尺燹更等，所以，相當便利。 第5實施型態. 第21圖表示第5實施型能 也i忍之冰相1之正視圖。在第2 j圖 中’關於附加與上述圖 -同付唬之兀件，與在上述實施 塑態中說明過的相同， . 所u在此4略說明。本實施型態之2148-10249-PF 19 1375779 Figure 20 shows the relationship between self-diagnosis abnormality information and load ratio adjustment. For example, in the case where only the LED 9 is blinked, the brightness changes when the light is turned on and when the light is turned off, so that the user of the refrigerator may be scared. However, as shown in Fig. 20, the light is not completely turned off, but the luminosity is gradually increased and decreased, so that the shape of the shell lamp is changed. Thus, the user is not scared, and the abnormality and the like can be notified. In addition, the above example proposes an example of displaying the self-breaking abnormality by adjusting the brightness generated by the load ratio adjustment, and also selecting the adjustment of the LED 9 luminosity generated by the load ratio adjustment according to the preference of the refrigerator user. This can be used. The adjustment of the redundancy of the illumination device is performed from the operation panel 21 in Fig. 17, and the user of the refrigerator 1 can arbitrarily set the luminosity of L.ED9. For example, 'Use the refrigerator in a place that is brighter around! When the external light is incident on the V to 2. Oh, the light that is generated is not so much needed, so reduce the photometric level issued by the deletion. For example, when it is necessary to illuminate the inside of the refrigerating compartment 2 in the storage of the interior of the refrigerating compartment, it is expected to further reduce the power consumption by increasing the photometric level. As described above, according to the fourth embodiment, when the LED 9 is caused to emit light, the load ratio is adjusted to 'do not flash, but the illuminance of the LED 9 is increased or decreased, whereby the user can be scared without It reports abnormal conditions and the like. In addition, the user can enter the setting and change the competition, so it is quite convenient. Fifth embodiment. Fig. 21 is a front view showing the ice phase 1 of the fifth embodiment. In the figure 2 j, the same as the above-mentioned drawings and the same as those described in the above-mentioned embodiment, the same as those described in the above-mentioned embodiment of the plastic state, which will be briefly described here.

例如，當取出朝向冷藏室2放入左側之貯藏品時，使用 者可僅開啟左Η6Β取出，當取出放入右側之食品時，可僅 開啟右⑽。當大大開啟門扉#，冷藏室2内部之冷氣之流 出量變多，所以’消耗電力隨之增加。因此，藉由在右； 6Α或左門6Β中僅開啟其中―纟，可使取出貯藏品時之門靡 之開啟程度盡可能地小，抑制無意義之電力祕。因此， 無論右門以或左門6Β中任何_者開啟，需要使設置於冷藏 室2内部之照明裝置1(^LED9發光，照明冷藏室2内部所 以，如第21圖所示’分別設置門靡開關2仏24β。控制裝 置1〇〇根據從門扉開關24Α，24Β所傳送過來之訊號，判斷右 門6Α、左門6Β是否開啟’進行與照明裝置對應之照明。 本貫施型態在具有右門6A或左門6B之冰箱丨A中設置將 上述實施型態所說明過之LED9作為光源的照明裝置1〇，進 步抑制無意義之電力消耗。例如，將開啟左門6B取出之 貯藏品收納於開啟門扉時可看到之範圍内的冷藏室2左 側。反之，開啟右門6A取出貯藏品之情況亦相同。於是， 右可在從所開啟之門扉所看到之範圍内照明冷藏室2内 部’可得到所需要之充份效果。 第22圖表示第5實施型態之LED9所產生的冷藏室2内部 之知、明。如第22(a)圖所示，當開啟左門⑽時，僅使設置於 左侧之巧側壁13的照明裝置丨〇之LED9亮燈，反之，如第22(b) 圖所不，畲開啟右門6A時，僅使設置於右側之内側壁丨3的 2148-1Q249-PF 21 1375779 照明裝置1G之删亮燈。又，如第22(e)_所示，當共㈣ 啟右門6A及左門晴，使設置於左右兩邊之内側壁以的照 明裝置10之LED9亮燈’藉此’可照明整個冷藏室^如上所 述’可藉由便宜且壽命長之半導體元件進行與副之亮燈/ 熄燈有關的開關之切換’所以’較分別使左右内側壁13 上之照明裝置10亮燈/熄燈，也不必擔心成本提高。For example, when the storage placed on the left side toward the refrigerating compartment 2 is taken out, the user can open only the left Η6Β, and when the food placed on the right side is taken out, the right (10) can be turned on only. When the threshold # is greatly opened, the amount of cooling air inside the refrigerating compartment 2 is increased, so the power consumption increases. Therefore, by opening only the "纟" in the right; 6Α or the left door 6Β, the opening degree of the threshold when the storage is taken out can be made as small as possible, suppressing the meaningless power secret. Therefore, regardless of whether the right door or any of the left door 6 is opened, it is necessary to set the illuminating device 1 provided inside the refrigerating compartment 2 (^LED9 emits light, illuminates the inside of the refrigerating compartment 2, so as shown in Fig. 21, respectively, the sill switch is set 2仏24β. The control device 1 determines whether the right door 6Α and the left door 6Β are turned on according to the signal transmitted from the threshold switches 24Α, 24Β. The illumination is corresponding to the illumination device. The present embodiment has the right door 6A or the left door. In the refrigerator 丨A of 6B, the illuminating device 1 which uses the LED 9 described in the above embodiment as a light source is provided, and the improvement suppresses the meaningless power consumption. For example, the storage which takes the opening of the left door 6B is stored in the opening threshold and can be seen. To the left of the refrigerating compartment 2 within the range. On the contrary, the case where the right door 6A is opened to take out the storage is the same. Thus, the right can illuminate the inside of the refrigerating compartment 2 within the range seen from the opened threshold ' Fig. 22 shows the inside of the refrigerator compartment 2 generated by the LED 9 of the fifth embodiment. As shown in Fig. 22(a), when the left door (10) is opened, it is only placed on the left side. The LED 9 of the illumination device of the side wall 13 lights up. Conversely, as shown in the 22nd (b) figure, when the right door 6A is opened, only the 2148-1Q249-PF 21 1375779 disposed on the inner side wall 丨3 of the right side is provided. In addition, as shown in the 22nd (e)_, when the common door (4) and the left door are opened, the LEDs 9 of the illuminating device 10 disposed on the inner side walls of the left and right sides are illuminated. 'It is possible to illuminate the entire refrigerating compartment ^ as described above. 'The switch of the switch related to the turn-on/turn-off of the sub-light can be performed by the inexpensive and long-life semiconductor element. Therefore, the illumination device 10 on the left and right inner side walls 13 is respectively brighter. Lights/lights off, don't worry about cost increases.

A refrigerator 1 that consumes less power than required and consumes less power. In the fifth embodiment, in the fifth embodiment, only the right door 6A and the left door are turned on, and the illumination device 10 is turned on, but the installation position and mounting angle of the illumination device are included. Alternatively, the illuminating device 1 disposed on the inner side wall 13 in the opposite direction to the opened sill may be as described above, and the pointing characteristic of the LED 9 is stronger, so that the position of the illuminating device is different depending on the setting position of the illuminating device. The illumination range can be illuminated widely and efficiently by irradiating the vicinity with a certain degree of illumination. Therefore, the control device 1 determines the right door 6A based on the signal transmitted from the threshold switches 24A, 24B. Whether the left door 6B is turned on to perform illumination corresponding to the illumination device 。. Fig. 23 shows the illumination inside the refrigerator compartment 2 generated by the LED 9 of the sixth embodiment. As shown in Fig. 23(a), when the trick is opened At 6B, only the LED 9 of the illumination device 1 disposed on the inner side wall 13 of the left side is turned on. Conversely, as shown in the figure 23 (b) 2148-10249-PF 22 1375779, when the right door 6 A is opened, only Make the inner side wall 1 on the right side The LED 9 of the illuminating device 10 of 3 is turned on. Further, as shown in Fig. 23(c), when the right door 6A and the left door 6B are jointly opened, the LED 9 of the illuminating device 1 disposed on the inner side walls 13 on the left and right sides is turned on. The lighting 'by this' can illuminate the entire refrigerating compartment 2. As described above, according to the sixth embodiment, in the refrigerator 1 having the right door 6A and the left door 6B, there is a distance between the rack 8 and the lighting device 1 In the case where any one of the right door 6 A or the left door 6B is opened, only the LED 9 of the illumination device 1 disposed on the inner side wall 13 of the opposite side of the opened threshold is illuminated to illuminate the desired position. Therefore, it is possible to obtain a refrigerator 1 that prevents power consumption and power consumption that exceeds demand. The seventh cargo type. Fig. 24 shows the interior of the refrigerator compartment 2 generated by the illumination device (LED9) of the seventh embodiment. In the fifth and sixth embodiments described above, an example in which the illumination device 设置 is provided on both sides of the inner side wall 13 of the refrigerating chamber 2 has been presented. For example, with the volume inside the refrigerating chamber 2, the luminosity of the LED 9, and the like. The difference is that if the inner side wall 13 of one of the left and right sides is provided with illumination In the present embodiment, the illumination device 1 is disposed on the inner side wall 13 of one of the right and left sides (in the figure 24, it is disposed on the inner side of the left side). Wall 1 3) Here, the number of LEDs 9 as the light source of the illumination device is the same as the number of LEDs 9 when the illumination device 1 is disposed on the left and right inner side walls 13 as in the fifth and sixth embodiments, and all the LEDs 9 The total amount of luminescence (energy related to luminescence) does not change, so that it is ensured that the amount of luminescence inside the refrigerator compartment 2 is sufficiently illuminated in the fifth and sixth embodiments. 2148-1024 9-PF 23 1375779 Moreover, in the space inside the refrigerating compartment 2, the overlapping portion of the effective illumination range α of each LED 9 is increased, so that the number of arrangements is the same as the number of LEDs 9 disposed in the left and right side walls 13 LED9 can also get lighting effects. As a result, the same brightness can be obtained by a smaller number of LEDs 9 than when the illumination device 1 is disposed on the left and right inner side walls 13, reducing the number of LEDs 9 used. Fig. 25 shows an example of control when the illumination device ί3 is provided in the inner side wall 丨3 of one of the left and right sides. As described above, if the LED 9 can only illuminate the range seen when the door # 开启 is opened, the required sufficient illumination effect can be obtained. For example, when the lighting device 1 is disposed on the left and right inner side walls 13, the lighting device 10 of one of the lighting devices 10 is turned on with the door opening, whereby sufficient lighting effect and low power consumption can be achieved. For example, even in the case where the illumination device 10 is provided only on the inner side wall 13 of one side, an approximately equivalent effect can be achieved by adjusting the load ratio of the crucible. According to the signals from the threshold switches 24A, 24B, the control device 1 When it is judged that the left and right thresholds are opened, the above load ratio is made 1%% and the LED 9 is illuminated. For example, when it is judged that one of the thresholds is opened, the load ratio is about 50%. To make the LED 9 emit light. Also, the case where the threshold of the side on which the illumination device is disposed (near the side of the illumination device i) and the threshold of the opposite side (the side away from the illumination device) are opened. The brightness of the light of the LED 9 is different. For example, in the case where the threshold of the side on which the illumination device 10 is disposed is turned on, the LED 9 is caused to emit light with a load ratio of about 40%, and the illumination device is disposed at the same time. In the case where the threshold on the opposite side of the side is turned on, the LED 9 is caused to emit light with a load ratio of about 0.6%. In addition, the brightness of the light generated by the deletion can be different from 2148-10249-PF 24 丄W779.胄 from the Pg The lighting mode inside the refrigerating compartment 2 is constant. In addition, the power consumption can be suppressed by adjusting the duty ratio. In addition to the example of adjusting the duty ratio according to the distance from the lighting device 1〇, Also • The load ratio can be adjusted according to the area that must be illuminated.

The brightness and the position of the _ required for the illumination can be obtained by the refrigerator 1 which prevents the power of the demand and the low power consumption. In particular, in the refrigerator i in which the illumination device 10 is disposed on the inner side wall 13 of one of the left and right sides, the load ratio is changed by judging whether the threshold to be opened is close to the threshold of the illumination device 10 or away from the threshold of the illumination device 10. Therefore, it is possible to make fine adjustments such as the sun and the moon. Eighth embodiment. Fig. 25 is a plan view of the refrigerator compartment 2 of the eighth embodiment. In the above embodiment, the illuminating device is mounted in a state where the excitation phase 9 is the angle 0 of the optical axis of the inner side wall 13 greater than • 60 degrees, whereby the optical axis 12 of the LED 9 does not directly enter the shelf 8 edge. In the present embodiment, the illuminating device 1 is mounted in such a manner that the light in the direction of the optical axis 12 of the optical axis 12 is not directly incident on the rack 8 so that the angle of the optical axis 12 with respect to the optical axis 12 of the inner side wall 13 is less than 3 degrees. Hey. With the shape of the inner side wall 13 or the like, the angle of the optical axis 12 is less than 30 degrees, and the light in the secret direction is not directly incident on the rack 8. Further, when the entire reefer chamber 2 is irradiated by making the angle θ smaller than 30 degrees, the light of (4) can be removed by the light generated by the concave portion UA, and the light can be well balanced. 2148-10249-PF 25 1375779 Figure 26 shows the relationship between the LED 9 and the inner side wall 13. The effective irradiation range β when the angle β of 1^09 with respect to the optical axis of the inner side wall 13 is less than 30 degrees is as shown in Fig. 26(a). In addition, the rear side of the refrigerator compartment 2 provided in the recessed portion 13A of the inner side wall 13 in the present embodiment has a shape having a curved portion 13B. As for the light emitted from the LED 9, the light traveling in the right direction along the optical axis 12 is directly incident on the refrigerator compartment 2 as shown in Fig. 26(b), and is irradiated to the inside of the refrigerator compartment 2. On the other hand, the light beam traveling in the left direction along the optical axis 12 is reflected in the concave portion 13A as shown in Fig. 26(c). Here, when the light incident on the portion other than the curved portion 13? is reflected, it enters the inside of the refrigerating chamber 2. The light reflected by the light incident on the curved portion 13 前进 advances in the direction of the door pocket η of the opened threshold to illuminate the door cover 11. Thus, the light of the optical axis 12 of the LED 9 is not directly incident on the rack 8, so that the user of the refrigerator 1 does not feel dizzy by the reflected light generated by the rack 8. In addition, the light generated by the LED 9 is directly incident on the refrigerating chamber 2

Fig. 27 is a view showing the reflection strategy of the light in the concave portion 13 of the eighth embodiment. As shown in Fig. 27(a), if nothing is done, the light reflecting the inner side wall 3 is weak. On the other hand, the 27th (3)th graph shows that the high reflection element 13C for increasing the reflectance of the light is added to the entire concave surface of the concave portion 13A. By attaching the high reflection element 13C, the light traveling in the direction of the concave portion 13 can be efficiently reflected. Here, the material of the high reflection element nc is not particularly limited. However, aluminum or the like may be used as a material, and the high reflection element 13C may be formed by a technique such as vapor deposition. 2148-1024 9-PF 26 1375779 Fig. 27(c) shows a case where the high reflection element 13C is added to a portion other than the curved portion 13B of the concave portion 13A. As mentioned above, the light reflected by the part of the curved portion advances in the direction of the door sill of the opened threshold. If the reflectance is too high, the light reflected in front of the refrigerating compartment 2 will be too strong, the refrigerator Users may be dazzled. Therefore, the light incident on the portion other than the curved portion i3B is reflected at a high reflectance and incident on the inside of the storage chamber 2, and the light incident on the curved portion 13B is weakened by reflection. Further, as shown in Fig. 27(4), a lamp cover 25 which weakens the light traveling in the direction of the door cover by the action of diffusion, attenuation, or the like can be provided.
