　しかしながら、特許文献１および２に記載の冷蔵庫のように、照明装置を庫内の壁面に設けられた凹部に配置した場合、冷蔵庫の筐体に設けられたウレタンおよび真空断熱材等の断熱部材を照明装置の分だけ減らす必要があるため、断熱性能が悪化してしまう。 However, when the lighting device is arranged in the recess provided on the wall surface of the refrigerator as in the refrigerators described in Patent Documents 1 and 2, the heat insulating member such as urethane and vacuum heat insulating material provided in the refrigerator housing is used. Since it is necessary to reduce the amount by the amount of the lighting device, the heat insulating performance deteriorates.
　また、冷蔵庫の扉には、食品を収納するドアポケットが設けられているが、特許文献３に記載の冷蔵庫のように、照明装置を天井壁面等に延設した場合、庫内の視認性を向上させることができるが、ドアポケットおよびドアポケットに収納される食品と、照明装置とが接触する虞がある。そのため、ドアポケットに収納される食品の大きさが制限されてしまう。この場合、ドアポケットに収納される食品が制限されないように、ドアポケットの大きさおよび配置位置等の仕様を変更することも考えられる。しかしながら、ドアポケットは、ユーザからの要求に基づいて予め決められた大きさの食品が収納できるようになっているため、ドアポケットの仕様を変更することは、非常に困難である。 Further, the door of the refrigerator is provided with a door pocket for storing food, but when the lighting device is extended to the ceiling wall surface or the like as in the refrigerator described in Patent Document 3, the visibility inside the refrigerator is improved. Although it can be improved, there is a risk that the door pocket and the food stored in the door pocket come into contact with the lighting device. Therefore, the size of food stored in the door pocket is limited. In this case, it is conceivable to change the specifications such as the size and arrangement position of the door pocket so that the food stored in the door pocket is not restricted. However, it is very difficult to change the specifications of the door pocket because the door pocket can store food of a predetermined size based on the request from the user.
　すなわち、特許文献２に記載の冷蔵庫では、断熱性能の悪化を抑制するとともに、庫内の視認性を向上させることができるが、ドアポケットに収納される食品が制限されてしまう。 That is, in the refrigerator described in Patent Document 2, deterioration of heat insulation performance can be suppressed and visibility inside the refrigerator can be improved, but foods stored in the door pocket are limited.
　本発明は、上記従来の技術における課題に鑑みてなされたものであって、収納される食品に対する制限および収納量の低下を抑制することができる冷蔵庫を提供することを目的とする。 The present invention has been made in view of the above-mentioned problems in the prior art, and an object of the present invention is to provide a refrigerator capable of suppressing restrictions on foods to be stored and a decrease in storage amount.
　本発明の冷蔵庫は、開口面を有し、内部の食品の冷凍および冷蔵の少なくとも一方を行う貯蔵室と、前記貯蔵室内に設けられ、前記食品を収納する収納棚と、前記開口面に開閉自在に設けられた貯蔵室扉と、前記貯蔵室扉の前記貯蔵室側の面に設けられ、前記食品を収納するドアポケットと、前記貯蔵室内に設けられ、前記貯蔵室内に光を照射する照明装置とを備え、前記照明装置は、前記貯蔵室扉を開閉した際の前記ドアポケットの移動範囲外に配置されているものである。 The refrigerator of the present invention has an opening surface, a storage chamber for freezing and refrigerating food inside, a storage shelf provided in the storage chamber for storing the food, and an openable / closable opening surface. A storage room door provided in the storage room door, a door pocket provided on the storage room side surface of the storage room door for storing the food, and a lighting device provided in the storage room to irradiate the storage room with light. The lighting device is arranged outside the moving range of the door pocket when the storage room door is opened and closed.
　以上のように、本発明によれば、照明装置が貯蔵室扉を開閉した際のドアポケットの移動範囲外に配置される。これにより、ドアポケットおよびドアポケットに収納された食品に接触しない位置に照明装置が配置されるため、収納される食品に対する制限および収納量の低下を抑制することができる。 As described above, according to the present invention, the lighting device is arranged outside the moving range of the door pocket when the storage room door is opened and closed. As a result, since the lighting device is arranged at the door pocket and the position where it does not come into contact with the food stored in the door pocket, it is possible to suppress the limitation on the food to be stored and the decrease in the storage amount.

実施の形態１．
　本実施の形態１に係る冷蔵庫について説明する。本実施の形態１に係る冷蔵庫は、庫内を照らすことができる照明装置を備えたものである。 Embodiment 1.
The refrigerator according to the first embodiment will be described. The refrigerator according to the first embodiment is provided with a lighting device capable of illuminating the inside of the refrigerator.
［冷蔵庫１００の構成］
　図１は、本実施の形態１に係る冷蔵庫１００の一例を示す外観図である。なお、以下の説明において、右側および左側は、冷蔵庫１００の前面側から背面側に向かう方向（前後方向）を正面としたときの方向を示す。すなわち、右側は、図１の紙面の右側に対応し、左側は、図１の紙面の左側に対応するものとする。また、以下では、左側から右側へ向かう方向（左右方向）をｘ方向とし、前面側から背面側へ向かう方向（前後方向）をｙ方向とし、上面側から下面側へ向かう方向（上下方向）をｚ方向として説明する。 [Structure of refrigerator 100]
FIG. 1 is an external view showing an example of the refrigerator 100 according to the first embodiment. In the following description, the right side and the left side indicate the direction when the direction from the front side to the back side (front-back direction) of the refrigerator 100 is the front side. That is, the right side corresponds to the right side of the paper surface of FIG. 1, and the left side corresponds to the left side of the paper surface of FIG. Further, in the following, the direction from the left side to the right side (left-right direction) is the x direction, the direction from the front side to the back side (front-back direction) is the y direction, and the direction from the upper surface side to the lower surface side (vertical direction). This will be described as the z direction.
　図１に示すように、冷蔵庫１００は、外郭を構成する筐体１００Ａを備える。筐体１００Ａは、前面に開口を有する外箱（図示せず）と、仕切壁で各貯蔵室が区画され、外箱の開口から外箱内に嵌め込まれた内箱（図示せず）と、外箱と内箱との空間に充填されたウレタンまたは真空断熱材などの断熱部材（図示せず）とで構成された、断熱性を有する箱体である。冷蔵庫１００は、筐体１００Ａ内に、上段から順に、冷蔵室１、筐体１００Ａの左右方向に併設された製氷室２および切替室３、野菜室４ならびに冷凍室５を貯蔵室として備えている。 As shown in FIG. 1, the refrigerator 100 includes a housing 100A that constitutes an outer shell. The housing 100A includes an outer box having an opening on the front surface (not shown), an inner box (not shown) in which each storage chamber is partitioned by a partition wall and fitted into the outer box through the opening of the outer box. It is a box body having heat insulating properties, which is composed of a heat insulating member (not shown) such as urethane or a vacuum heat insulating material filled in the space between the outer box and the inner box. The refrigerator 100 includes a refrigerating chamber 1, an ice making chamber 2 and a switching chamber 3, a vegetable compartment 4 and a freezing chamber 5 provided in the left-right direction of the housing 100A in this order from the top. ..
　冷蔵室１、製氷室２および切替室３、野菜室４ならびに冷凍室５の各貯蔵室には、それぞれ貯蔵室扉が設けられている。冷蔵室１の開口面には、図示しないヒンジを軸として回転方向に開閉する観音開き式扉１Ａが設けられている。観音開き式扉１Ａは、例えば、左右で幅が異なる一対の扉で形成されている。製氷室２には、引出式扉２Ａが前後に開閉自在に設けられている。同様に、切替室３には引出式扉３Ａが設けられ、野菜室４には引出式扉４Ａが設けられ、冷凍室５には引出式扉５Ａが設けられている。 Each storage room of the refrigerating room 1, the ice making room 2, the switching room 3, the vegetable room 4, and the freezing room 5 is provided with a storage room door. A double door 1A that opens and closes in a rotational direction about a hinge (not shown) is provided on the opening surface of the refrigerator compartment 1. The double door 1A is formed of, for example, a pair of doors having different widths on the left and right sides. The ice making chamber 2 is provided with a pull-out door 2A that can be opened and closed in the front-rear direction. Similarly, the switching room 3 is provided with a pull-out door 3A, the vegetable room 4 is provided with a pull-out door 4A, and the freezing room 5 is provided with a pull-out door 5A.
　冷蔵庫１００は、上述した構成に限定されるものではない。例えば、冷蔵庫１００は、製氷室２および切替室３を設けないで構成してもよい。また、冷蔵庫１００は、野菜室４および冷凍室５の位置を逆に構成してもよい。 The refrigerator 100 is not limited to the above-described configuration. For example, the refrigerator 100 may be configured without the ice making chamber 2 and the switching chamber 3. Further, the refrigerator 100 may be configured with the positions of the vegetable compartment 4 and the freezing chamber 5 reversed.
　図２は、図１に示す線分Ａ－Ａを矢印方向から見た場合の冷蔵庫１００の内部構造図である。図２に示すように、冷蔵室１、製氷室２、切替室３、野菜室４および冷凍室５の各貯蔵室は、隣接する貯蔵室との間での熱の移動を遮断する断熱仕切り壁６によって仕切られている。 FIG. 2 is an internal structural diagram of the refrigerator 100 when the line segments AA shown in FIG. 1 are viewed from the direction of the arrow. As shown in FIG. 2, each storage room of the refrigerating room 1, the ice making room 2, the switching room 3, the vegetable room 4 and the freezing room 5 has a heat insulating partition wall that blocks heat transfer from the adjacent storage room. It is partitioned by 6.
　冷蔵室１には、食品１０を収納するための１または複数の収納棚１ａが上下方向（ｚ方向）に設けられている。収納棚１ａは、例えば透過性を有する部材で形成されている。また、観音開き式扉１Ａには、食品１０を収納するための１または複数のドアポケット１ｂが設けられている。ドアポケット１ｂは、観音開き式扉１Ａの庫内側の面に、予め決められた高さの食品１０が収納できるように設けられている。 The refrigerating room 1 is provided with one or a plurality of storage shelves 1a for storing the food 10 in the vertical direction (z direction). The storage shelf 1a is made of, for example, a transparent member. Further, the double door 1A is provided with one or a plurality of door pockets 1b for storing the food 10. The door pocket 1b is provided on the inner surface of the double door 1A so that food 10 having a predetermined height can be stored.
　さらに、冷蔵室１の内部には、冷蔵室１内に光を照射する照明装置７が設けられている。照明装置７は、例えば、発光源として少なくとも１つのＬＥＤが用いられ、冷蔵庫１００に設けられた図示しない制御基板から供給される点灯信号に基づき、ＬＥＤの点灯および消灯を行う。本実施の形態１において、照明装置７は、収納棚１ａよりも前面側かつ冷蔵室１の天井壁面に設けられている。 Further, inside the refrigerating room 1, a lighting device 7 for irradiating the inside of the refrigerating room 1 with light is provided. For example, the lighting device 7 uses at least one LED as a light emitting source, and turns on and off the LED based on a lighting signal supplied from a control board (not shown) provided in the refrigerator 100. In the first embodiment, the lighting device 7 is provided on the front side of the storage shelf 1a and on the ceiling wall surface of the refrigerating room 1.
［照明装置７の配置］
　照明装置７の配置について、図３～図５を参照して説明する。図３は、照明装置７が収納棚１ａの上部に設けられた場合の、照明装置７による光の照射について説明するための概略図である。図４は、照明装置７が収納棚１ａよりも前面側に設けられた場合の、照明装置７による光の照射について説明するための概略図である。なお、図３および図４は、ユーザＵによって冷蔵室１の観音開き式扉１Ａが開かれた状態を示す。 [Arrangement of lighting device 7]
The arrangement of the lighting device 7 will be described with reference to FIGS. 3 to 5. FIG. 3 is a schematic view for explaining the irradiation of light by the lighting device 7 when the lighting device 7 is provided on the upper part of the storage shelf 1a. FIG. 4 is a schematic view for explaining the irradiation of light by the lighting device 7 when the lighting device 7 is provided on the front side of the storage shelf 1a. 3 and 4 show a state in which the double door 1A of the refrigerator compartment 1 is opened by the user U.
　図３に示す例では、照明装置７が収納棚１ａの上部に設けられ、収納棚１ａの前面側に光が照射されるように光軸Ｌが設定されている。この場合、収納棚１ａの前面側に食品１０が配置されると、照明装置７からの光が食品１０によって遮られる。そのため、照明装置７からの光が一部の食品１０の前面に照射されず、ユーザＵが観音開き式扉１Ａを開いて冷蔵室１内を見たときの冷蔵室１内の視認性が悪化する。 In the example shown in FIG. 3, the lighting device 7 is provided on the upper part of the storage shelf 1a, and the optical axis L is set so that the front side of the storage shelf 1a is irradiated with light. In this case, when the food 10 is arranged on the front side of the storage shelf 1a, the light from the lighting device 7 is blocked by the food 10. Therefore, the light from the lighting device 7 does not irradiate the front surface of some foods 10, and the visibility inside the refrigerator compartment 1 deteriorates when the user U opens the double door 1A and looks inside the refrigerator compartment 1. ..
　これに対して、図４に示す例では、照明装置７が収納棚１ａの前面側であり、収納棚１ａの前面側に光が照射されるように光軸Ｌが設定されている。この場合、収納棚１ａの前面側に食品１０が配置されても、食品１０によって遮られる光の量が減少する。これにより、光がすべての食品１０の前面に照射されるため、ユーザＵが観音開き式扉１Ａを開いて冷蔵室１内を見たときの視認性が向上する。 On the other hand, in the example shown in FIG. 4, the lighting device 7 is on the front side of the storage shelf 1a, and the optical axis L is set so that the front side of the storage shelf 1a is irradiated with light. In this case, even if the food 10 is arranged on the front side of the storage shelf 1a, the amount of light blocked by the food 10 is reduced. As a result, the light is radiated to the front surface of all the foods 10, so that the visibility when the user U opens the double door 1A and looks inside the refrigerator compartment 1 is improved.
　このように、冷蔵室１内の照明装置７の配置位置によって、冷蔵室１内の視認性が大きく異なる。そこで、本実施の形態１に係る冷蔵庫１００では、冷蔵室１内の視認性が向上するように、照明装置７が収納棚１ａよりも前面側に設けられるようにする。 As described above, the visibility in the refrigerating room 1 greatly differs depending on the arrangement position of the lighting device 7 in the refrigerating room 1. Therefore, in the refrigerator 100 according to the first embodiment, the lighting device 7 is provided on the front side of the storage shelf 1a so as to improve the visibility in the refrigerator compartment 1.
　図５は、図２の冷蔵室１を上面から見た場合の内部構造図である。上述したように、冷蔵室１内において、観音開き式扉１Ａのドアポケット１ｂは、３５０ｍｌの缶などの予め決められた高さの食品１０が収納できるようになっている。照明装置７が収納棚１ａよりも前面側かつ天井壁面に設けられている場合、照明装置７の配置位置によっては、観音開き式扉１Ａが閉じられた際に、照明装置７がドアポケット１ｂに収納された食品１０と衝突する可能性がある。 FIG. 5 is an internal structural view of the refrigerating chamber 1 of FIG. 2 as viewed from above. As described above, in the refrigerator compartment 1, the door pocket 1b of the double door 1A can store food 10 having a predetermined height such as a 350 ml can. When the lighting device 7 is provided on the front side of the storage shelf 1a and on the ceiling wall surface, the lighting device 7 is stored in the door pocket 1b when the double door 1A is closed depending on the arrangement position of the lighting device 7. May collide with the food 10 that has been made.
　そこで、本実施の形態１における照明装置７は、図５に示すように、観音開き式扉１Ａを回転方向（図５の点線矢印方向）に開閉させた際に、ドアポケット１ｂおよびドアポケット１ｂに収納された食品１０と衝突しない位置に設けられる。すなわち、照明装置７は、観音開き式扉１Ａと共に回転するドアポケット１ｂの移動範囲外となる位置に設けられる。 Therefore, as shown in FIG. 5, the lighting device 7 in the first embodiment has the door pocket 1b and the door pocket 1b when the double door 1A is opened and closed in the rotation direction (the direction of the dotted arrow in FIG. 5). It is provided at a position where it does not collide with the stored food 10. That is, the lighting device 7 is provided at a position outside the moving range of the door pocket 1b that rotates together with the double door 1A.
［照明装置７による光の照射角度］
　次に、照明装置７による光の照射角度について説明する。本実施の形態１に係る照明装置７は、左右方向であるｘ軸回り、前後方向であるｙ軸回り、および、上下方向であるｚ軸回りに予め設定された角度で光軸Ｌが傾斜するように設置される。 [Light irradiation angle by the lighting device 7]
Next, the irradiation angle of light by the lighting device 7 will be described. In the lighting device 7 according to the first embodiment, the optical axis L is tilted at preset angles around the x-axis in the left-right direction, the y-axis in the front-rear direction, and the z-axis in the up-down direction. It is installed as.
（光軸Ｌのｘ軸回りの傾斜角度）
　図６は、照明装置７における光軸Ｌのｘ軸回りの傾斜角度について説明するための概略図である。図６は、冷蔵室１を側面側から見た場合であって、冷蔵室１の観音開き式扉１Ａが開かれた状態を示す。図６に示すように、照明装置７は、鉛直方向（ｚ方向）を基準として、ｘ軸回りに角度αだけ冷蔵室１の背面壁側（ｙ方向）に光軸Ｌが傾斜するように設けられている。このときの角度αは、０～９０°とすると好ましい。 (Inclination angle around the x-axis of the optical axis L)
FIG. 6 is a schematic view for explaining an inclination angle of the optical axis L around the x-axis in the lighting device 7. FIG. 6 shows a case where the refrigerating room 1 is viewed from the side surface side, and shows a state in which the double door 1A of the refrigerating room 1 is opened. As shown in FIG. 6, the lighting device 7 is provided so that the optical axis L is inclined toward the back wall side (y direction) of the refrigerating chamber 1 by an angle α around the x-axis with reference to the vertical direction (z direction). Has been done. The angle α at this time is preferably 0 to 90 °.
（光軸Ｌのｚ軸回りの傾斜角度）
　図７は、照明装置７における光軸Ｌのｚ軸回りの傾斜角度について説明するための概略図である。図７は、冷蔵室１を上面側から見た場合であって、冷蔵室１の観音開き式扉１Ａが開かれた状態を示す。図７に示すように、照明装置７は、前後方向（ｙ方向）を基準として、ｚ軸回りに角度βだけ左右方向（ｘ方向）に光軸Ｌが傾斜するように設けられている。 (Inclination angle of the optical axis L around the z-axis)
FIG. 7 is a schematic view for explaining the inclination angle of the optical axis L around the z-axis in the lighting device 7. FIG. 7 is a view of the refrigerating room 1 from the upper surface side, showing a state in which the double door 1A of the refrigerating room 1 is opened. As shown in FIG. 7, the lighting device 7 is provided so that the optical axis L is inclined in the left-right direction (x direction) by an angle β around the z-axis with reference to the front-back direction (y direction).
（光軸Ｌのｙ軸回りの傾斜角度）
　図８は、照明装置７における光軸Ｌのｙ軸回りの傾斜角度について説明するための概略図である。図８は、冷蔵室１を正面側から見た場合であって、冷蔵室１の観音開き式扉１Ａが開かれた状態を示す。図８に示すように、照明装置７は、鉛直方向（ｚ方向）を基準として、ｙ軸回りに角度γだけ左右方向（ｘ方向）に光軸Ｌが傾斜するように設けられている。 (Inclination angle of the optical axis L around the y-axis)
FIG. 8 is a schematic view for explaining the inclination angle of the optical axis L around the y-axis in the lighting device 7. FIG. 8 shows a case where the refrigerating room 1 is viewed from the front side, and shows a state in which the double door 1A of the refrigerating room 1 is opened. As shown in FIG. 8, the lighting device 7 is provided so that the optical axis L is inclined in the left-right direction (x direction) by an angle γ around the y-axis with reference to the vertical direction (z direction).
　このように、光軸Ｌの角度α、βおよびγを設定した場合、光軸Ｌが庫内の中心方向に向けられるため、照明装置７は、冷蔵室１内の前面側かつ正面から見て中心方向から食品１０の前面を全体的に照らすことができる。これにより、冷蔵室１内に収納された食品１０の視認性を向上させることができる。また、冷蔵室１内の側面壁および背面壁に光が照射されるため、冷蔵室１内が明るく見え、清潔感を向上させることができる。さらに、照明装置７の光軸Ｌが背面壁側に向けられているため、ユーザが観音開き式扉１Ａを開いて冷蔵室１内を見た場合に、光軸Ｌがユーザの視線に入りにくくなる。そのため、ユーザに対する眩しさを軽減することができる。 When the angles α, β, and γ of the optical axis L are set in this way, the optical axis L is directed toward the center of the refrigerator, so that the lighting device 7 is viewed from the front side and the front side of the refrigerator compartment 1. The front surface of the food 10 can be illuminated as a whole from the central direction. As a result, the visibility of the food 10 stored in the refrigerator compartment 1 can be improved. Further, since the side wall and the back wall in the refrigerator compartment 1 are irradiated with light, the inside of the refrigerator compartment 1 looks bright and the feeling of cleanliness can be improved. Further, since the optical axis L of the lighting device 7 is directed toward the back wall side, when the user opens the double door 1A and looks inside the refrigerator compartment 1, it becomes difficult for the optical axis L to enter the user's line of sight. .. Therefore, it is possible to reduce glare to the user.
　なお、光軸Ｌのｚ軸回りおよびｙ軸回りのそれぞれの傾斜角度βおよびγは、観音開き式扉１Ａの一対の扉における左右方向（ｘ方向）の幅が異なる場合に設定すると好ましい。観音開き式扉１Ａの一対の扉における左右方向（ｘ方向）の幅が異なる場合、照明装置７は、観音開き式扉１Ａの一対の扉の幅が異なることによって、正面側から見て中心からずれた位置に設置されることになる。この場合に光軸Ｌの角度βおよびγを設定することにより、照明装置７の光軸Ｌが中心方向に向くため、冷蔵室１内を全体的に照らすことができる。そして、冷蔵室１内をより均一に照らすことができるため、冷蔵室１内に収納された食品１０の視認性を向上させることができる。 It is preferable to set the inclination angles β and γ of the optical axis L around the z-axis and the y-axis when the widths in the left-right direction (x direction) of the pair of double doors 1A are different. When the widths of the pair of double doors 1A in the left-right direction (x direction) are different, the lighting device 7 is deviated from the center when viewed from the front side due to the different widths of the pair of double doors 1A. It will be installed in the position. In this case, by setting the angles β and γ of the optical axis L, the optical axis L of the lighting device 7 faces toward the center, so that the inside of the refrigerating chamber 1 can be illuminated as a whole. Then, since the inside of the refrigerating chamber 1 can be illuminated more uniformly, the visibility of the food 10 stored in the refrigerating chamber 1 can be improved.
　以上のように、本実施の形態１に係る冷蔵庫１００において、照明装置７は、観音開き式扉１Ａを開閉した際に、観音開き式扉１Ａと共に回転するドアポケット１ｂの移動範囲外に配置される。これにより、照明装置７と、ドアポケット１ｂおよびドアポケット１ｂに収納された食品１０との衝突が防止される。そのため、予め決められた高さの食品１０をドアポケット１ｂへ収納できるので、ドアポケット１ｂに収納される食品１０に対する制限を設ける必要がない。そして、照明装置７は、収納棚１ａの上部でもなく、ドアポケット１ｂの移動範囲内でもない、食品１０を配置することができない箇所に配置されている。そのため、冷蔵室１内における食品１０の収納量を減らすことなく照明装置７を配置することができる。 As described above, in the refrigerator 100 according to the first embodiment, the lighting device 7 is arranged outside the moving range of the door pocket 1b that rotates together with the double door 1A when the double door 1A is opened and closed. As a result, the collision between the lighting device 7 and the door pocket 1b and the food 10 stored in the door pocket 1b is prevented. Therefore, since the food 10 having a predetermined height can be stored in the door pocket 1b, it is not necessary to set a restriction on the food 10 stored in the door pocket 1b. The lighting device 7 is arranged in a place where the food 10 cannot be arranged, which is neither the upper part of the storage shelf 1a nor the moving range of the door pocket 1b. Therefore, the lighting device 7 can be arranged without reducing the storage capacity of the food 10 in the refrigerating room 1.
　また、照明装置７は、冷蔵室１の壁面に埋め込むようにして配置されるものではなく、壁面に取り付けられるものである。これにより、照明装置７は、冷蔵庫１００の筐体１００Ａを構成する断熱部材を減らすことなく配置されるため、冷蔵庫１００の断熱性の悪化を抑制しながら、冷蔵室１内の視認性を向上させることができる。 Further, the lighting device 7 is not arranged so as to be embedded in the wall surface of the refrigerating chamber 1, but is attached to the wall surface. As a result, the lighting device 7 is arranged without reducing the heat insulating members constituting the housing 100A of the refrigerator 100, so that the visibility in the refrigerator compartment 1 is improved while suppressing the deterioration of the heat insulating property of the refrigerator 100. be able to.
　さらに、従来の冷蔵庫からの設計変更の際には、照明装置７の配置位置を変更するだけであり、配置位置の変更に伴う追加の部品および作業工程が発生しない。そのため、コストの上昇を抑制しながら、上記の効果を得ることができる。 Furthermore, when the design is changed from the conventional refrigerator, only the arrangement position of the lighting device 7 is changed, and additional parts and work processes are not generated due to the change of the arrangement position. Therefore, the above effect can be obtained while suppressing the increase in cost.
　本実施の形態１に係る冷蔵庫１００において、照明装置７は、収納棚１ａよりも前面側に配置されるとともに、収納棚１ａに収納された食品１０に対して光を照射するように光軸Ｌが設定されている。これにより収納棚１ａに食品１０が収納されている状態であっても、収納棚１ａの前面に対して全体的に光が照射される。そのため、冷蔵室１内の視認性を向上させることができる。 In the refrigerator 100 according to the first embodiment, the lighting device 7 is arranged on the front side of the storage shelf 1a, and the optical axis L so as to irradiate the food 10 stored in the storage shelf 1a with light. Is set. As a result, even when the food 10 is stored in the storage shelf 1a, the front surface of the storage shelf 1a is totally irradiated with light. Therefore, the visibility in the refrigerator compartment 1 can be improved.
　本実施の形態１に係る冷蔵庫１００において、照明装置７は、左右方向を示す軸回りに光軸Ｌが傾斜するように配置されている。また、照明装置７は、上下方向を示す軸回りに光軸Ｌが傾斜するように配置されている。さらに、照明装置７は、前後方向を示す軸回りに光軸Ｌが傾斜するように配置されている。 In the refrigerator 100 according to the first embodiment, the lighting device 7 is arranged so that the optical axis L is inclined around an axis indicating the left-right direction. Further, the lighting device 7 is arranged so that the optical axis L is inclined around an axis indicating the vertical direction. Further, the lighting device 7 is arranged so that the optical axis L is inclined around an axis indicating the front-rear direction.
　これにより、照明装置７は、冷蔵室１内の前面側かつ正面から見て中心方向から食品１０の前面を全体的に照らすことができる。そのため、冷蔵室１内に収納された食品１０の視認性を向上させることができる。また、冷蔵室１内の側面壁および背面壁に光が照射されるため、冷蔵室１内が明るく見え、清潔感を向上させることができる。さらに、照明装置７の光軸Ｌが背面壁側に向けられているため、ユーザが観音開き式扉１Ａを開いて冷蔵室１内を見た場合に、光軸Ｌがユーザの視線に入りにくくなり、ユーザに対する眩しさを軽減することができる。 As a result, the lighting device 7 can illuminate the front surface of the food 10 as a whole from the center direction when viewed from the front side and the front side in the refrigerator compartment 1. Therefore, the visibility of the food 10 stored in the refrigerator compartment 1 can be improved. Further, since the side wall and the back wall in the refrigerator compartment 1 are irradiated with light, the inside of the refrigerator compartment 1 looks bright and the feeling of cleanliness can be improved. Further, since the optical axis L of the lighting device 7 is directed toward the back wall side, it becomes difficult for the optical axis L to enter the user's line of sight when the user opens the double door 1A and looks inside the refrigerator compartment 1. , The glare to the user can be reduced.
実施の形態２．
　次に、本実施の形態２について説明する。本実施の形態２では、観音開き式扉１Ａに設けられた回転仕切体の回転方向を誘導するガイドピンを利用して、照明装置７を配置する場合について説明する。なお、本実施の形態２において、実施の形態１と共通する部分には同一の符号を付し、詳細な説明を省略する。 Embodiment 2.
Next, the second embodiment will be described. In the second embodiment, a case where the lighting device 7 is arranged by using a guide pin for guiding the rotation direction of the rotating partition body provided in the double door 1A will be described. In the second embodiment, the same reference numerals are given to the parts common to the first embodiment, and detailed description thereof will be omitted.
　図９は、本実施の形態２に係る冷蔵庫１００を側面側から見た場合の冷蔵室１の内部構造図である。図９は、冷蔵室１の観音開き式扉１Ａが開かれた状態を示す。一般に、冷蔵庫１００の冷蔵室１に観音開き式扉１Ａが設けられている場合、観音開き式扉１Ａを構成する一対の扉の一方には、観音開き式扉１Ａが閉じられた際に形成される一対の扉の間の隙間を閉塞するための図示しない回転仕切体１ｃ（図５参照）が設けられている。また、図９に示すように、冷蔵室１側には、回転仕切体１ｃに対応するようにガイドピン２０が設けられている。 FIG. 9 is an internal structural view of the refrigerator compartment 1 when the refrigerator 100 according to the second embodiment is viewed from the side surface side. FIG. 9 shows a state in which the double door 1A of the refrigerator compartment 1 is opened. Generally, when a double door 1A is provided in the refrigerator room 1 of the refrigerator 100, one of the pair of doors constituting the double door 1A is a pair formed when the double door 1A is closed. A rotating partition 1c (see FIG. 5) (not shown) is provided to close the gap between the doors. Further, as shown in FIG. 9, a guide pin 20 is provided on the refrigerating chamber 1 side so as to correspond to the rotary partition body 1c.
　ガイドピン２０は、観音開き式扉１Ａに設けられた回転仕切体１ｃの回転方向を誘導するために設けられている。ガイドピン２０は、天井壁面の、観音開き式扉１Ａと対向する位置に設けられている。 The guide pin 20 is provided to guide the rotation direction of the rotary partition body 1c provided on the double door 1A. The guide pin 20 is provided on the ceiling wall surface at a position facing the double door 1A.
　図１０は、図９の照明装置７およびガイドピン２０の一例を示す概略図である。図１０に示すように、本実施の形態２において、ガイドピン２０は、天井壁面に配置された照明装置７よりも前面側に設けられている。すなわち、照明装置７は、ガイドピン２０の背面側に設けられる。また、ガイドピン２０の背面を形成する背面部２０ａは、正面から見た際に、照明装置７の高さよりも高く形成されている。 FIG. 10 is a schematic view showing an example of the lighting device 7 and the guide pin 20 of FIG. As shown in FIG. 10, in the second embodiment, the guide pin 20 is provided on the front side of the lighting device 7 arranged on the ceiling wall surface. That is, the lighting device 7 is provided on the back side of the guide pin 20. Further, the back surface portion 20a forming the back surface of the guide pin 20 is formed higher than the height of the lighting device 7 when viewed from the front surface.
　このようにして照明装置７が配置された場合、図９に示すように、ユーザＵが観音開き式扉１Ａを開けて冷蔵室１内を正面から見た場合、照明装置７は、ガイドピン２０によってユーザＵの視界に入らず、ユーザＵに認識させないように配置される。また、照明装置７から照射される光により、冷蔵室１内は明るくなる一方で、ユーザＵに対して照明装置７から直接照射される光がガイドピン２０の背面によって遮られる。そのため、ユーザＵが照明装置７からの直接光によって感じる不快な眩しさを抑制することができる。また、上記のようにして照明装置７から光が照射される場合には、冷蔵室１内全体が明るくなるため、冷蔵室１内の明るさの均整度を高めることができ、視認性および清潔感をより向上させることができる。 When the lighting device 7 is arranged in this way, as shown in FIG. 9, when the user U opens the double door 1A and looks at the inside of the refrigerating room 1 from the front, the lighting device 7 is operated by the guide pin 20. It is arranged so that it does not enter the user U's field of view and is not recognized by the user U. Further, the light emitted from the lighting device 7 brightens the inside of the refrigerating chamber 1, while the light directly emitted from the lighting device 7 to the user U is blocked by the back surface of the guide pin 20. Therefore, it is possible to suppress the unpleasant glare that the user U feels due to the direct light from the lighting device 7. Further, when the lighting device 7 irradiates the light as described above, the entire inside of the refrigerating chamber 1 becomes bright, so that the degree of brightness balance in the refrigerating chamber 1 can be improved, and the visibility and cleanliness can be improved. The feeling can be further improved.
　また、照明装置７はユーザＵから認識されないため、ユーザＵからは、冷蔵室１内が相対的に明るく見える。さらに、照明装置７がユーザＵから認識されないことにより、照明装置７は、間接照明としての役割を果たし、冷蔵庫１００の意匠性を高めることができる。さらにまた、ガイドピン２０は、観音開き式扉１Ａを備える従来の冷蔵庫に設けられているものであるため、従来の冷蔵庫から本実施の形態２に係る冷蔵庫１００へ設計変更する際には、部品点数が増加することなく、安価に冷蔵庫の設計変更を行うことができる。 Further, since the lighting device 7 is not recognized by the user U, the inside of the refrigerating room 1 looks relatively bright from the user U. Further, since the lighting device 7 is not recognized by the user U, the lighting device 7 serves as indirect lighting, and the design of the refrigerator 100 can be enhanced. Furthermore, since the guide pin 20 is provided in the conventional refrigerator provided with the double door 1A, the number of parts is increased when the design is changed from the conventional refrigerator to the refrigerator 100 according to the second embodiment. It is possible to change the design of the refrigerator at low cost without increasing the number of doors.
　なお、図９および図１０に示す例では、照明装置７とガイドピン２０とが別体で形成された場合について説明したが、これに限られず、例えば照明装置７とガイドピン２０とが一体的に形成されてもよい。 In the examples shown in FIGS. 9 and 10, the case where the lighting device 7 and the guide pin 20 are formed separately has been described, but the present invention is not limited to this, and for example, the lighting device 7 and the guide pin 20 are integrated. May be formed in.
　図１１は、図９の照明装置７およびガイドピン２０の他の例を示す概略図である。図１１に示すように、照明装置７は、ガイドピン２０の背面部２０ａを当該装置のカバー部の前面部として用いて接続されている。 FIG. 11 is a schematic view showing another example of the lighting device 7 and the guide pin 20 of FIG. As shown in FIG. 11, the lighting device 7 is connected by using the back surface portion 20a of the guide pin 20 as the front surface portion of the cover portion of the device.
　このように、照明装置７とガイドピン２０とを一体的に形成することにより、部品点数を削減できるとともに、一体的に形成された照明装置７とガイドピン２０とを一度に組み付けることができるため、冷蔵庫１００の製造工程を削減することができる。したがって、冷蔵庫１００を安価かつ短時間で製造することができる。 By integrally forming the lighting device 7 and the guide pin 20 in this way, the number of parts can be reduced, and the integrally formed lighting device 7 and the guide pin 20 can be assembled at the same time. , The manufacturing process of the refrigerator 100 can be reduced. Therefore, the refrigerator 100 can be manufactured inexpensively and in a short time.
　また、照明装置７およびガイドピン２０を取り付ける際に、それぞれをネジを用いて冷蔵室１内に取り付ける必要がなくなるため、ネジ止め点数を削減することができる。そのため、ネジ止めに必要な作業時間および使用するネジの個数による価格を低減することができる。そして、これによっても、冷蔵庫１００をより安価かつ短時間で製造することができる。 Further, when installing the lighting device 7 and the guide pin 20, it is not necessary to install each of them in the refrigerating chamber 1 using screws, so that the number of screwing points can be reduced. Therefore, it is possible to reduce the price due to the working time required for screwing and the number of screws used. And this also makes it possible to manufacture the refrigerator 100 at a lower cost and in a shorter time.
　さらに、照明装置７のカバー部の一部がガイドピン２０によって代用されることにより、カバーを小型化することができるため、照明装置７を安価に製造することができる。さらにまた、照明装置７とガイドピン２０とが一体的に形成されるため、図９および図１０に示す例と比較して、ユーザＵは、照明装置７をより認識し難くなる。そのため、照明装置７の間接照明としての役割をより高めることができ、意匠性をさらに向上させることができる。 Further, since a part of the cover portion of the lighting device 7 is replaced by the guide pin 20, the cover can be miniaturized, so that the lighting device 7 can be manufactured at low cost. Furthermore, since the lighting device 7 and the guide pin 20 are integrally formed, it becomes more difficult for the user U to recognize the lighting device 7 as compared with the examples shown in FIGS. 9 and 10. Therefore, the role of the lighting device 7 as indirect lighting can be further enhanced, and the design can be further improved.
　以上のように、本実施の形態２に係る冷蔵庫１００において、照明装置７は、ガイドピン２０の背面側に配置されている。このとき、ガイドピン２０は、背面部２０ａの高さが照明装置７の高さよりも高く形成されると好ましい。これにより、照明装置７は、ユーザＵに認識させないように配置されるため、ユーザＵが感じる不快な眩しさを抑制することができるとともに、冷蔵室１内を相対的に明るく見せることができる。 As described above, in the refrigerator 100 according to the second embodiment, the lighting device 7 is arranged on the back side of the guide pin 20. At this time, the guide pin 20 is preferably formed so that the height of the back surface portion 20a is higher than the height of the lighting device 7. As a result, since the lighting device 7 is arranged so as not to be recognized by the user U, the unpleasant glare felt by the user U can be suppressed, and the inside of the refrigerating room 1 can be made to appear relatively bright.
　また、本実施の形態２に係る冷蔵庫１００において、照明装置７とガイドピン２０とが一体的に形成されている。これにより、製造工程および製造コスト等が削減されるため、冷蔵庫１００を安価かつ短時間で製造することができる。 Further, in the refrigerator 100 according to the second embodiment, the lighting device 7 and the guide pin 20 are integrally formed. As a result, the manufacturing process, the manufacturing cost, and the like are reduced, so that the refrigerator 100 can be manufactured at low cost and in a short time.
　以上、冷蔵庫１００の実施の形態１および２について説明したが、冷蔵庫１００は、上述した実施の形態１および２に限定されるものではなく、要旨を逸脱しない範囲内で様々な変形や応用が可能である。実施の形態１および２では、貯蔵室である冷蔵室１の貯蔵室扉として、一対の扉で構成された観音開き式扉１Ａが設けられている場合を例にとって説明したが、これはこの例に限られない。例えば、貯蔵室扉は、１つの扉で構成された片開き式扉が用いられてもよい。 Although the first and second embodiments of the refrigerator 100 have been described above, the refrigerator 100 is not limited to the above-described first and second embodiments, and various modifications and applications can be made without departing from the gist. Is. In the first and second embodiments, a case where a double door 1A composed of a pair of doors is provided as a storage room door of the refrigerating room 1 which is a storage room has been described as an example. Not limited. For example, as the storage room door, a single door composed of one door may be used.
　図１２は、片開き式扉１Ｂが設けられた冷蔵室１を上面から見た場合の内部構造図である。図１２に示すように、冷蔵室１の開口面には、図示しないヒンジを軸として回転方向に開閉する１つの扉で形成された片開き式扉１Ｂが設けられている。片開き式扉１Ｂには、観音開き式扉１Ａと同様に、１または複数のドアポケット１ｂが設けられている。 FIG. 12 is an internal structural view of the refrigerator compartment 1 provided with the single door 1B when viewed from above. As shown in FIG. 12, the opening surface of the refrigerating chamber 1 is provided with a single door 1B formed by one door that opens and closes in a rotational direction about a hinge (not shown). Like the double door 1A, the single door 1B is provided with one or a plurality of door pockets 1b.
　この場合においても、実施の形態１および２と同様に、照明装置７は、片開き式扉１Ｂを回転方向（図１２の点線矢印方向）に開閉させた際に、ドアポケット１ｂおよびドアポケット１ｂに収納された食品１０と衝突しない位置に設ければよい。すなわち、照明装置７は、片開き式扉１Ｂと連動するドアポケット１ｂの移動範囲外となる位置に設ければよい。 Also in this case, similarly to the first and second embodiments, the lighting device 7 opens and closes the single door 1B in the rotation direction (the direction of the dotted arrow in FIG. 12), and the door pocket 1b and the door pocket 1b It may be provided at a position where it does not collide with the food 10 stored in the door. That is, the lighting device 7 may be provided at a position outside the moving range of the door pocket 1b that is interlocked with the single door 1B.
　なお、実施の形態２のように、照明装置７がユーザＵに認識されないようにする場合には、実施の形態２のガイドピン２０に代わる部品を、照明装置７の前面側に配置すればよい。このとき、照明装置７の前面側に配置される部品の高さは、照明装置７の高さよりも高くなるようにすると好ましい。 If the lighting device 7 is not recognized by the user U as in the second embodiment, a component replacing the guide pin 20 of the second embodiment may be arranged on the front side of the lighting device 7. .. At this time, it is preferable that the height of the parts arranged on the front side of the lighting device 7 is higher than the height of the lighting device 7.
　また、実施の形態１および２では、照明装置７の発光源としてＬＥＤを用いた場合について説明したが、これに限られず、白熱電球等の他の発光部品を発光源として用いてもよい。例えば、照明装置７の発光源として白熱電球を用いた場合、ＬＥＤを用いた場合と比較して、発光部品のコストを低減することができるため、照明装置７全体のコストを低減することができる。 Further, in the first and second embodiments, the case where the LED is used as the light emitting source of the lighting device 7 has been described, but the present invention is not limited to this, and other light emitting parts such as an incandescent light bulb may be used as the light emitting source. For example, when an incandescent light bulb is used as the light emitting source of the lighting device 7, the cost of the light emitting component can be reduced as compared with the case where the LED is used, so that the cost of the entire lighting device 7 can be reduced. ..
　照明装置７の発光源としてのＬＥＤは、１個に限られず、複数個であってもよい。ＬＥＤを複数個用いることにより、冷蔵室１内に照射される光のムラを抑制することができる。また、ＬＥＤを複数個用いる場合において、ＬＥＤの個数を増加させることにより、光のムラをさらに抑制することができる。一方、ＬＥＤの個数を減少させることにより、発光部品のコストを低減することができるため、照明装置７全体のコストを低減することができる。 The number of LEDs as a light emitting source of the lighting device 7 is not limited to one, and may be a plurality. By using a plurality of LEDs, it is possible to suppress unevenness of the light emitted into the refrigerating chamber 1. Further, when a plurality of LEDs are used, unevenness of light can be further suppressed by increasing the number of LEDs. On the other hand, by reducing the number of LEDs, the cost of the light emitting component can be reduced, so that the cost of the entire lighting device 7 can be reduced.
　また、照明装置７は、天井壁面に配置される場合に限られず、例えば、床壁面または側壁面に配置されてもよい。さらに、照明装置７は、冷蔵室１に配置される場合に限られず、冷凍室５等の他の貯蔵室に配置されてもよい。 Further, the lighting device 7 is not limited to the case where it is arranged on the ceiling wall surface, and may be arranged on the floor wall surface or the side wall surface, for example. Further, the lighting device 7 is not limited to the case where it is arranged in the refrigerating room 1, and may be arranged in another storage room such as the freezing room 5.
　さらに、照明装置７による光の照射角度は、予め設定される場合に限られず、例えばユーザＵによって任意に変更できるようにしてもよい。これにより、冷蔵室１内への食品１０の収納状態に応じて、光の照射状態を適切に設定することができる。 Further, the irradiation angle of the light by the lighting device 7 is not limited to the case where it is set in advance, and may be arbitrarily changed by, for example, the user U. Thereby, the light irradiation state can be appropriately set according to the storage state of the food 10 in the refrigerating room 1.
