Description

本発明の実施形態は冷蔵庫に関する。   Embodiments described herein relate generally to a refrigerator.

冷蔵庫内に比較的強い臭いを発する食品や腐敗した食品が入っていると、その臭いが冷蔵庫内の他の食品に移ったり、利用者が冷蔵庫を開けた時に臭いがしたりする。これを防ぐため、ダクト内に脱臭や除菌の効果のある空気浄化装置が設けられた冷蔵庫が提案されている（例えば特許文献１〜３参照）。   If food that emits a relatively strong odor or spoiled food is contained in the refrigerator, the odor moves to other foods in the refrigerator, or smells when the user opens the refrigerator. In order to prevent this, a refrigerator in which an air purification device having an effect of deodorization and sterilization is provided in a duct has been proposed (see, for example, Patent Documents 1 to 3).

脱臭効果や除菌効果を大きくするためには、空気浄化装置がダクト内でも風量の多い場所に設けられて、多くの冷気が空気浄化装置を通過できるようになっていることが望ましい。しかし、空気浄化装置は風圧を損失させるため、風量の多い場所に空気浄化装置が設けられると、ダクトから貯蔵室へ出て行く冷気の風圧が低くなり、冷気が貯蔵室内を十分に循環できなくなり、貯蔵室内の冷却が不十分になるおそれがある。   In order to increase the deodorizing effect and the sterilizing effect, it is desirable that the air purification device is provided in a place where there is a large amount of air even in the duct so that a lot of cool air can pass through the air purification device. However, since the air purification device loses the wind pressure, if the air purification device is installed in a place with a large air volume, the wind pressure of the cold air going out from the duct to the storage chamber will be low, and the cold air will not be able to circulate sufficiently in the storage chamber There is a risk that cooling in the storage chamber will be insufficient.

本実施形態について図面に基づき説明する。   This embodiment will be described with reference to the drawings.

図１に示すように、実施形態に係る冷蔵庫１０は冷蔵空間２０と冷凍空間３０とを有する。冷蔵空間２０は、冷蔵温度（例えば、２〜３℃）に冷却される空間であって、必要に応じて内部がさらに区画されている。例えば図１の冷蔵庫１０の場合は、冷蔵空間２０の内部が仕切板によって上下に区画され、上は複数段の載置棚が設けられた冷蔵室２２に、下は引き出し式の収納容器が配置された野菜室２４となっている。冷凍空間３０は、冷凍温度（例えば、−１８℃以下）に冷却される空間であって、自動製氷機を備えた製氷室３２と、冷凍室３４とが設けられている。冷蔵室２２、野菜室２４、製氷室３２、冷凍室３４等の貯蔵室の前方開口部は、それぞれ、観音式や引き出し式等の扉により閉塞されている。   As shown in FIG. 1, the refrigerator 10 according to the embodiment includes a refrigerated space 20 and a frozen space 30. The refrigeration space 20 is a space that is cooled to a refrigeration temperature (for example, 2 to 3 ° C.), and the inside thereof is further partitioned as necessary. For example, in the case of the refrigerator 10 shown in FIG. 1, the inside of the refrigeration space 20 is partitioned up and down by a partition plate, the top is a refrigeration chamber 22 provided with a plurality of stages of mounting shelves, and the bottom is a drawer-type storage container. It is a vegetable room 24 made. The freezing space 30 is a space cooled to a freezing temperature (for example, −18 ° C. or lower), and is provided with an ice making chamber 32 equipped with an automatic ice making machine and a freezing chamber 34. Front openings of storage rooms such as the refrigerator compartment 22, the vegetable compartment 24, the ice making compartment 32, and the freezer compartment 34 are closed by doors such as a kannon type and a drawer type.

冷凍空間３０の奥には背面カバー３６が設けられている。背面カバー３６の裏側は、冷気を発生させる冷却器４５やファン４７が収納された冷却器室４６となっている。冷却器室４６で発生した冷気は、ファン４７によって冷凍空間３０に送られ、冷凍空間３０内を循環した後、冷却器室４６に設けられた開口を通って冷却器室４６に戻る。   A back cover 36 is provided at the back of the freezing space 30. The back side of the back cover 36 is a cooler chamber 46 in which a cooler 45 and a fan 47 that generate cool air are housed. The cool air generated in the cooler chamber 46 is sent to the refrigeration space 30 by the fan 47, circulates in the refrigeration space 30, and then returns to the cooler chamber 46 through an opening provided in the cooler chamber 46.

冷蔵空間２０の奥には背面カバー２６が設けられている。背面カバー２６は、その裏側に、ダクト４０を形成している。ダクト４０の内部は冷気の流路となっている。背面カバー２６の複数箇所に、ダクト４０から冷蔵空間２０へ冷気が出て行くための開口２７が形成されている。ダクト４０の下には、冷気を発生させる冷却器４１が収納された冷却器室４２が設けられている。ダクト４０の範囲は、冷却器４１の冷気の流れ方向側の端部４１ａから、背面カバー２６に形成された開口２７までである。冷気はダクト４０内を下から上へ流れる。冷却器室４２で発生した冷気は、ダクト４０を通って冷蔵空間２０に流入し、冷蔵空間２０内を冷蔵温度に冷却した後、冷却器室４２に設けられた開口を通って冷却器室４２に戻る。   A back cover 26 is provided in the back of the refrigerated space 20. The back cover 26 has a duct 40 formed on the back side thereof. The inside of the duct 40 is a cold air flow path. Openings 27 through which cold air goes out from the duct 40 to the refrigerated space 20 are formed at a plurality of locations on the back cover 26. Under the duct 40, a cooler chamber 42 in which a cooler 41 for generating cool air is housed is provided. The range of the duct 40 is from the end 41 a of the cooler 41 on the cold air flow direction side to the opening 27 formed in the back cover 26. The cold air flows in the duct 40 from the bottom to the top. The cool air generated in the cooler chamber 42 flows into the refrigerating space 20 through the duct 40, cools the inside of the refrigerating space 20 to the refrigerating temperature, and then passes through an opening provided in the cooler chamber 42. Return to.

ダクト４０内の下部には、冷気を循環させるファン４３が設けられている。本実施形態では、２つのファン４３ａ、４３ｂ（図４〜６参照）が、ダクト４０内の冷気の流れる方向に対して垂直な面内に並べて設けられている。図１の冷蔵庫では、２つのファン４３ａ、４３ｂは、奥方向（冷蔵庫正面から見て左右方向）に並んでいる。   A fan 43 that circulates cold air is provided in the lower part of the duct 40. In the present embodiment, two fans 43 a and 43 b (see FIGS. 4 to 6) are provided side by side in a plane perpendicular to the direction in which the cool air flows in the duct 40. In the refrigerator of FIG. 1, the two fans 43a and 43b are arranged in the back direction (left and right direction when viewed from the front of the refrigerator).

ファン４３よりも冷気の流れの下流側の場所には、空気浄化装置５０が設けられている。空気浄化装置５０は、空気を浄化できるもの、例えば、消臭・除菌・エチレン分解のうち少なくともいずれか１つの効果を奏するものであれば良い。空気浄化装置５０の具体的な構造は限定されない。空気浄化装置５０の具体的な構造の例を３つ挙げる。   An air purification device 50 is provided at a location downstream of the fan 43 in the flow of cool air. The air purification device 50 may be any device that can purify air, for example, one that exhibits at least one effect of deodorization, sterilization, and ethylene decomposition. The specific structure of the air purification apparatus 50 is not limited. Three examples of the specific structure of the air purification device 50 will be given.

１つ目の例を図２に示す。１つ目の例の空気浄化装置５０ａは、平行に並べられた２枚のフィルタ５１、５１と、それらを挟むように配置された基板５２、５２と、フィルタ５１、５１及び基板５２、５２を収納するフレーム５３とを備える。   A first example is shown in FIG. The air purification device 50a of the first example includes two filters 51 and 51 arranged in parallel, substrates 52 and 52 arranged so as to sandwich them, filters 51 and 51, and substrates 52 and 52. And a frame 53 for storage.

フィルタ５１は冷気が透過できるものである。フィルタ５１には可視光応答型光触媒が吸着されている。可視光応答型光触媒とは、可視光が当たると活性化する光触媒のことで、例えば、窒素ドープ型酸化チタン、銅系化合物担持酸化チタン、銅系化合物担持酸化タングステン、等が挙げられる。基板５２には多数の孔５４が開けられている。また、基板５２にはフィルタ５１に向かって可視光を発する複数の光源５５が設けられている。フレーム５３の基板５２、５２と対向する２箇所には窓５６、５６が開けられている。そのため、冷気が空気浄化装置５０ａを通過できる。つまり、一方の窓５６からフレーム５３内に入った冷気が、基板５２の孔５４及びフィルタ５１を通過し、他方の窓５６からフレーム５３外に出ることができる。   The filter 51 can transmit cold air. A visible light responsive photocatalyst is adsorbed on the filter 51. The visible light responsive photocatalyst is a photocatalyst that is activated when exposed to visible light. Examples thereof include nitrogen-doped titanium oxide, copper-based compound-supported titanium oxide, and copper-based compound-supported tungsten oxide. A large number of holes 54 are formed in the substrate 52. The substrate 52 is provided with a plurality of light sources 55 that emit visible light toward the filter 51. Windows 56 and 56 are opened at two positions of the frame 53 facing the substrates 52 and 52. Therefore, cold air can pass through the air purification device 50a. In other words, the cool air that has entered the frame 53 from one window 56 can pass through the hole 54 and the filter 51 of the substrate 52 and exit from the other window 56 to the outside of the frame 53.

この空気浄化装置５０ａにおいて、光源５５が点灯すると、フィルタ５１の可視光応答型光触媒が活性化される。そのフィルタ５１を冷気が通過し可視光応答型光触媒と冷気とが接触すると、冷気に含まれている臭気成分や雑菌等が分解され除去される。従って、空気浄化装置５０ａの一方の窓５６（吸込口とする）から入った冷気は、浄化されて他方の窓５６から出てくる。   In the air purification device 50a, when the light source 55 is turned on, the visible light responsive photocatalyst of the filter 51 is activated. When the cool air passes through the filter 51 and the visible light responsive photocatalyst and the cool air come into contact with each other, odor components and germs contained in the cool air are decomposed and removed. Accordingly, the cold air that has entered from one window 56 (which serves as a suction port) of the air purification device 50 a is purified and exits from the other window 56.

２つ目の例を図３に示す。２つ目の例の空気浄化装置５０ｂは、平行に並べられた２枚のフィルタ６１、６１と、フィルタ６１、６１の間に配置された放電電極６２と、フィルタ６１、６１の両側に配置された対極６３、６３と、放電電極６２と対極６３との間に電圧を加える電源回路６４と、これらを収納するフレーム６５とを備える。   A second example is shown in FIG. The air purification device 50b of the second example is arranged on two sides of the filters 61 and 61, two filters 61 and 61 arranged in parallel, a discharge electrode 62 arranged between the filters 61 and 61, and the filters 61 and 61. And a power supply circuit 64 for applying a voltage between the discharge electrode 62 and the counter electrode 63, and a frame 65 for housing them.

フィルタ６１は冷気が透過できるものである。フィルタ６１には紫外線が当たると活性化する光触媒が吸着されている。紫外線が当たると活性化する光触媒としては、例えば二酸化チタンが挙げられる。放電電極６２と対極６３とには多数の孔が開けられている。またフレーム６５の対極６３、６３と対向する２箇所には窓６７、６７が開けられている。そのため冷気が空気浄化装置５０ｂを通過できる。つまり、一方の窓６７からフレーム６５内に入った冷気が、放電電極６２や対極６３の孔６６及びフィルタ６１を通過し、他方の窓６７からフレーム６５外に出ることができる。   The filter 61 can transmit cold air. The filter 61 adsorbs a photocatalyst that is activated when it is exposed to ultraviolet rays. An example of a photocatalyst that is activated when exposed to ultraviolet light is titanium dioxide. A number of holes are formed in the discharge electrode 62 and the counter electrode 63. In addition, windows 67 and 67 are opened at two positions facing the counter electrodes 63 and 63 of the frame 65. Therefore, cold air can pass through the air purification device 50b. That is, the cold air that has entered the frame 65 from one window 67 can pass through the discharge electrode 62, the hole 66 of the counter electrode 63 and the filter 61, and can go out of the frame 65 from the other window 67.

この空気浄化装置５０ｂにおいて、電源回路６４により放電電極６２と対極６３との間に電圧が加わると、これらの間に放電が起きて紫外線が発生する。その紫外線を受けてフィルタ６１の光触媒が活性化される。そのフィルタ６１を冷気が通過し光触媒と冷気とが接触すると、冷気に含まれている臭気成分や雑菌等が分解され除去される。従って、空気浄化装置５０ｂの一方の窓６７（吸込口とする）から入った冷気は、浄化されて他方の窓６７から出てくる。   In this air purification device 50b, when a voltage is applied between the discharge electrode 62 and the counter electrode 63 by the power supply circuit 64, a discharge occurs between them to generate ultraviolet rays. In response to the ultraviolet light, the photocatalyst of the filter 61 is activated. When the cool air passes through the filter 61 and the photocatalyst and the cool air come into contact with each other, the odor components and germs contained in the cool air are decomposed and removed. Accordingly, the cold air that has entered from one window 67 (which serves as a suction port) of the air purification device 50 b is purified and exits from the other window 67.

３つ目の例の空気浄化装置５０は、図示しないが、フレーム内に活性炭が充填されたものである。フレームには、冷気の吸込口となる窓と、冷気の吹出口となる窓とが設けられている。この空気浄化装置５０を冷気が通過すると、冷気内の臭気成分や雑菌等が活性炭に吸着され除去される。従って、空気浄化装置５０の吸込口から入った冷気は、浄化されて吹出口から出てくる。   The air purification device 50 of the third example is one in which activated carbon is filled in a frame, although not shown. The frame is provided with a window serving as a cold air inlet and a window serving as a cold air outlet. When the cold air passes through the air purifying device 50, the odor components and germs in the cold air are adsorbed and removed by the activated carbon. Therefore, the cold air that has entered from the suction port of the air purification device 50 is purified and comes out of the outlet.

図４〜６にファン４３ａ、４３ｂを示す。ファン４３ａ、４３ｂの回転軸４８は冷気の流れる方向すなわち上下方向に伸びており、ファン４３ａ、４３ｂの羽根４９は回転軸４８に垂直な面内で回る。そのためファン４３ａ、４３ｂは冷気を下から上へ送ることができる。冷気の流れる方向は、図４〜６に矢印Ａで示されている。図４〜６に示されているように、本実施形態では、ダクト４０内に、冷気の流れる方向に対して垂直にプレート４４が設けられ、そのプレート４４に形成された孔にファン４３ａ、４３ｂが嵌め込まれている。そのため、冷気はファン４３ａ、４３ｂを通過してプレート４４の下から上へ流れる。ただしプレート４４は無くても良い。プレート４４が無い場合は、冷気の一部は、ファン４３ａ、４３ｂを通過せずその横を通過する。   4 to 6 show the fans 43a and 43b. The rotation shafts 48 of the fans 43a and 43b extend in the direction in which the cool air flows, that is, the vertical direction, and the blades 49 of the fans 43a and 43b rotate in a plane perpendicular to the rotation shaft 48. Therefore, the fans 43a and 43b can send cold air from the bottom to the top. The direction in which the cold air flows is indicated by arrows A in FIGS. As shown in FIGS. 4 to 6, in this embodiment, a plate 44 is provided in the duct 40 perpendicular to the direction in which the cold air flows, and the fans 43 a and 43 b are formed in the holes formed in the plate 44. Is inserted. Therefore, the cold air flows from the bottom to the top of the plate 44 through the fans 43a and 43b. However, the plate 44 may not be provided. When there is no plate 44, a part of cool air passes the fan 43a, 43b without passing.

本実施形態では、前記の２つのファン４３ａ、４３ｂのうち、一方のファン４３ａ（空気浄化装置用ファンとする）のみが、空気浄化装置５０へ向けて送風するようになっている。そのための構造の例を以下に３つ挙げる。なお、空気浄化装置用ファン４３ａから送られる冷気の流れが他のファン４３ｂから送られる冷気の流れの影響を受けていたり、他のファン４３ｂが発生させる冷気の流れのうち主たる流れ以外の流れが空気浄化装置５０の吸込口に向かっていたりしても構わない。図４〜６では、空気浄化装置５０として、上記の空気浄化装置５０ａを例示している。   In the present embodiment, only one of the two fans 43 a and 43 b (referred to as an air purification device fan) blows air toward the air purification device 50. Three examples of structures for this purpose are given below. The flow of cold air sent from the air purification device fan 43a is influenced by the flow of cold air sent from the other fan 43b, or the flow other than the main flow among the flow of cold air generated by the other fan 43b. You may go to the suction inlet of the air purification apparatus 50. 4 to 6 exemplify the air purification device 50 a as the air purification device 50.

１つ目の例を図４に示す。１つ目の例では、空気浄化装置用ファン４３ａが、他のファン４３ｂよりも、空気浄化装置５０ａに近接している。空気浄化装置５０ａは、空気浄化装置用ファン４３ａの羽根４９が回転する領域よりも冷気の流れの下流側に当たる場所（図中に符号Ｌで示されている場所）を避けて設けられていても良いが、この場所に空気浄化装置５０ａが入っていても良い。   A first example is shown in FIG. In the first example, the air purification device fan 43a is closer to the air purification device 50a than the other fans 43b. Even if the air purifying device 50a is provided avoiding a place (a place indicated by a symbol L in the drawing) that hits the downstream side of the cold air flow from the region where the blades 49 of the air purifying fan 43a rotate. Although it is good, the air purification apparatus 50a may be contained in this place.

２つ目の例を図５に示す。２つ目の例では、空気浄化装置用ファン４３ａの冷気の流れの下流側の場所４０ａと他のファン４３ｂの冷気の流れの下流側の場所４０ｂとの間が、仕切壁７０で仕切られている。そして、空気浄化装置５０ａが、仕切壁７０よりも、空気浄化装置用ファン４３ａ側の場所に設けられている。空気浄化装置５０ａは、空気浄化装置用ファン４３ａの羽根４９が回転する領域よりも冷気の流れの下流側に当たる場所（図４に符号Ｌで示されている場所と同じ場所）を避けて設けられていても良い。仕切壁７０の高さは、空気浄化装置５０ａの冷気の流れの一番下流側の部分を超える高さであることが望ましい。つまり、仕切壁７０の頂部が、空気浄化装置５０ａの冷気の流れの一番下流側の部分よりも、冷気の流れの下流側の位置にあることが望ましい。   A second example is shown in FIG. In the second example, a partition wall 70 partitions a location 40a downstream of the cool air flow of the air purifier fan 43a and a location 40b downstream of the cool air flow of the other fan 43b. Yes. The air purifying device 50 a is provided at a location closer to the air purifying fan 43 a than the partition wall 70. The air purifying device 50a is provided avoiding a place where it hits the downstream side of the cold air flow from the region where the blades 49 of the air purifying fan 43a rotate (the same place as indicated by the symbol L in FIG. 4). May be. The height of the partition wall 70 is desirably a height that exceeds the most downstream portion of the cool air flow of the air purification device 50a. That is, it is desirable that the top portion of the partition wall 70 is located at a position downstream of the cool air flow with respect to the most downstream portion of the air purification device 50a.

３つ目の例を図６に示す。３つ目の例では、ファン４３ａ、４３ｂがなす列の一端部に、空気浄化装置５０ａが配置されている。ここで、ファンがなす列の一端部とは、列をなす複数のファンのうち一番端（最も外側）にあるファンの回転軸４８よりも外側で、そのファンよりも冷気の流れの下流側の部分のことである。またこの一端部に空気浄化装置５０ａが配置されているとは、この一端部に空気浄化装置５０ａの冷気の吸込口が位置するように配置されているという意味である。この場合も、空気浄化装置５０ａが、空気浄化装置用ファン４３ａの羽根４９が回転する領域よりも冷気の流れの下流側に当たる場所（図４に符号Ｌで示されている場所と同じ場所）を避けて設けられていても良い。   A third example is shown in FIG. In the third example, an air purification device 50a is arranged at one end of a row formed by the fans 43a and 43b. Here, the one end portion of the row formed by the fans is the outermost side of the rotation shaft 48 of the fan at the outermost end (outermost side) of the plurality of fans in the row, and the downstream side of the cool air flow from the fans. It is a part of. Further, the fact that the air purification device 50a is disposed at the one end means that the cold air suction port of the air purification device 50a is disposed at the one end. Also in this case, a place where the air purifying device 50a hits the downstream side of the flow of the cold air from the region where the blades 49 of the air purifying fan 43a rotate (the same place as indicated by the symbol L in FIG. 4). It may be provided avoiding.

冷蔵庫１０は、以上の３つの例の特徴のうちいずれか２つを備えていても良い。また以上の３つの例の特徴を全て備えていても良い。   The refrigerator 10 may include any two of the features of the above three examples. Moreover, you may provide all the characteristics of the above three examples.

いずれの例においても、空気浄化装置５０ａの配置の姿勢は限定されない。しかし、図５の例のように、空気浄化装置５０ａの冷気の吸込口（一方の窓５６）が、空気浄化装置用ファン４３ａの回転軸４８に平行な面内に設けられていることが望ましい。   In any example, the attitude of the air purification device 50a is not limited. However, as in the example of FIG. 5, it is desirable that the cold air suction port (one window 56) of the air purification device 50a is provided in a plane parallel to the rotation shaft 48 of the air purification device fan 43a. .

冷蔵庫１０は、冷却器４５、ファン４７、冷却器４１、ファン４３等を制御する制御部１１を備える。制御部１１は、空気浄化装置用ファン４３ａの回転数が他のファン４３ｂの回転数よりも大きくなるように制御することが望ましい。ただし、制御部１１が制御するまでもなく、空気浄化装置用ファン４３ａの回転数が他のファン４３ｂの回転数よりも大きい値で固定されていても良い。また、制御部１１は、冷蔵空間２０内の温度が所定温度よりも低い場合は、空気浄化装置用ファン４３ａのみが回転し他のファン４３ｂが回転しないよう制御することが望ましい。ここで所定温度とは、予め定められている温度のことで、例えば上記の冷蔵温度である。   The refrigerator 10 includes a control unit 11 that controls the cooler 45, the fan 47, the cooler 41, the fan 43, and the like. It is desirable that the control unit 11 performs control so that the rotation speed of the air purification device fan 43a is larger than the rotation speed of the other fan 43b. However, the control unit 11 does not need to control, and the rotation speed of the air purification device fan 43a may be fixed at a value larger than the rotation speed of the other fan 43b. In addition, when the temperature in the refrigerated space 20 is lower than the predetermined temperature, the control unit 11 desirably performs control so that only the air purification device fan 43a rotates and the other fans 43b do not rotate. Here, the predetermined temperature is a predetermined temperature, for example, the above-described refrigeration temperature.

上記実施形態の効果について説明する。   The effect of the above embodiment will be described.

本実施形態では、冷気の流れ方向に対して垂直な面内に複数のファン４３ａ、４３ｂが並べて設けられているため、冷蔵空間２０へ送られる冷気の風量が多い。そのため冷蔵空間２０が十分に冷却される。ここで、冷気は、空気浄化装置５０を通過すると、減速されてしまう。しかし、本実施形態では、複数のファン４３ａ、４３ｂのうち空気浄化装置用ファン４３ａのみが空気浄化装置５０へ送風するように構成されているため、他のファン４３ｂから送られる冷気は減速されずに冷蔵空間２０へ送られる。そのため、冷蔵空間２０へ送られる冷気の風量が多く、しかも安定している。よって、ダクト４０内に空気浄化装置５０が設けられていても、冷蔵空間２０が十分に冷却される。また、空気浄化装置用ファン４３ａが空気浄化装置５０へ送風するため、多くの冷気が空気浄化装置５０を通過できる。そのため空気浄化の効果が大きい。   In the present embodiment, since the plurality of fans 43a and 43b are provided side by side in a plane perpendicular to the flow direction of the cool air, the amount of the cool air sent to the refrigerating space 20 is large. Therefore, the refrigerated space 20 is sufficiently cooled. Here, the cold air is decelerated when it passes through the air purification device 50. However, in the present embodiment, only the air purification device fan 43a out of the plurality of fans 43a and 43b is configured to blow air to the air purification device 50. Therefore, the cold air sent from the other fans 43b is not decelerated. To the refrigerated space 20. Therefore, the amount of cool air sent to the refrigerated space 20 is large and stable. Therefore, even if the air purification device 50 is provided in the duct 40, the refrigerated space 20 is sufficiently cooled. Further, since the air purification device fan 43 a blows air to the air purification device 50, a lot of cold air can pass through the air purification device 50. Therefore, the effect of air purification is great.

ここで、図４〜６のようにファン４３ａ、４３ｂが並べて設けられている場合、これらのファン４３ａ、４３ｂから等距離の場所では、空気浄化装置用ファン４３ａから送られる冷気の流れとファン４３ｂから送られる冷気の流れとが打ち消し合っている。そのためこのような場所に空気浄化装置５０が配置された場合、空気浄化装置５０に十分な冷気が送られず、冷蔵空間２０の冷気が浄化されない。しかし上記実施形態のように、空気浄化装置用ファン４３ａが他のファン４３ｂよりも空気浄化装置５０に近接している場合、空気浄化装置５０周辺においては、空気浄化装置用ファン４３ａから送られる冷気の流れの強さが、他のファン４３ｂから送られる冷気の流れの強さに勝る。そのため空気浄化装置用ファン４３ａから送られる冷気が空気浄化装置５０へ冷気が届く。その結果、空気浄化装置５０に十分な冷気が送られ、冷蔵空間２０の冷気が浄化される。またこの場合、他のファン４３ｂから送られる冷気は空気浄化装置５０を通らずに冷蔵空間２０へ送られるため、冷蔵空間２０が十分に冷却される。   When the fans 43a and 43b are provided side by side as shown in FIGS. 4 to 6, the flow of the cold air sent from the air purification device fan 43a and the fan 43b are equidistant from the fans 43a and 43b. The flow of cold air sent from is counteracting. Therefore, when the air purification device 50 is disposed in such a place, sufficient cold air is not sent to the air purification device 50, and the cold air in the refrigerated space 20 is not purified. However, when the air purification device fan 43a is closer to the air purification device 50 than the other fans 43b as in the above embodiment, the cool air sent from the air purification device fan 43a is around the air purification device 50. The strength of the current flow is superior to the strength of the cool air flow sent from the other fan 43b. Therefore, the cold air sent from the air purification device fan 43 a reaches the air purification device 50. As a result, sufficient cold air is sent to the air purification device 50, and the cold air in the refrigerated space 20 is purified. Further, in this case, since the cold air sent from the other fan 43b is sent to the refrigerated space 20 without passing through the air purification device 50, the refrigerated space 20 is sufficiently cooled.

また、上記実施形態のように、空気浄化装置用ファン４３ａの冷気の流れの下流側の場所と他のファン４３ｂの冷気の流れの下流側の場所との間が、仕切壁７０で仕切られている場合は、より確実に、空気浄化装置用ファン４３ａによる冷気が他のファン４３ｂにより打ち消されずに空気浄化装置５０へ送風される。またこの場合、より確実に、ファン４３ｂによる冷気が空気浄化装置５０を経由せずに冷蔵空間２０へ送風される。   Further, as in the above-described embodiment, the partition wall 70 partitions the location downstream of the cool air flow of the air purification device fan 43a and the location downstream of the cool air flow of the other fan 43b. If so, the cool air from the air purification device fan 43a is blown to the air purification device 50 without being canceled by the other fans 43b. In this case, the cool air from the fan 43b is blown into the refrigerated space 20 without passing through the air purification device 50.

また、上記実施形態のように、ファン４３ａ、４３ｂがなす列の一端部に、空気浄化装置５０が配置されている場合も、より確実に、空気浄化装置用ファン４３ａによる冷気が他のファン４３ｂにより打ち消されずに空気浄化装置５０へ送風される。またこの場合、より確実に、ファン４３ｂによる冷気が空気浄化装置５０を経由せずに冷蔵空間２０へ送風される。   Further, as in the above-described embodiment, even when the air purification device 50 is disposed at one end of the row formed by the fans 43a and 43b, the cold air from the air purification device fan 43a is more reliably transferred to the other fans 43b. The air is blown to the air purifying device 50 without being canceled. In this case, the cool air from the fan 43b is blown into the refrigerated space 20 without passing through the air purification device 50.

また、空気浄化装置用ファン４３ａは、冷気を主にその回転軸４８方向へ送る。そのため、空気浄化装置５０の吸込口が空気浄化装置用ファン４３ａの回転軸４８に平行な面内に設けられている場合は、空気浄化装置５０は、空気浄化装置用ファン４３ａから送られる冷気の一部のみを吸い込むことになる。そのため、空気浄化装置５０が冷気を吸い込むことによる冷気の圧力損失を抑えることができ、冷蔵庫１０の冷却性能に大きな悪影響が出ることを抑えることができる。   The air purifying fan 43a sends cool air mainly in the direction of the rotation shaft 48. Therefore, when the suction port of the air purification device 50 is provided in a plane parallel to the rotation shaft 48 of the air purification device fan 43a, the air purification device 50 is adapted to receive the cold air sent from the air purification device fan 43a. Only a part will be inhaled. Therefore, the pressure loss of the cold air due to the air purification device 50 sucking in the cold air can be suppressed, and it is possible to suppress a significant adverse effect on the cooling performance of the refrigerator 10.

また、空気浄化装置５０が、空気浄化装置用ファン４３ａの羽根４９が回転する領域よりも冷気の流れの下流側に当たる場所を避けて設けられている場合、空気浄化装置５０が空気浄化装置用ファン４３ａからの冷気の流れを阻害しない。そのため、冷蔵空間２０が十分に冷却され、しかも冷気が浄化される。   Further, when the air purification device 50 is provided so as to avoid a place where the air purification device 43 hits the downstream side of the flow of cold air from the region where the blades 49 of the air purification device fan 43a rotate, the air purification device 50 is provided with the air purification device fan. It does not inhibit the flow of cold air from 43a. Therefore, the refrigerated space 20 is sufficiently cooled, and the cold air is purified.

また、空気浄化装置用ファン４３ａから送られる冷気の少なくとも一部が、空気浄化装置５０で減速させられることにより、冷気の圧力損失が生じる。しかし、空気浄化装置用ファン４３ａの回転数が他のファン４３ｂの回転数よりも大きい場合は、空気浄化装置用ファン４３ａから送られる冷気は、空気浄化装置５０で減速させられたとしても、十分な圧力を保持することができる。そのためダクト４０内に空気浄化装置５０が設けられていても、冷蔵庫１０の冷却性能に大きな悪影響が無い。   Further, at least a part of the cold air sent from the air purification device fan 43a is decelerated by the air purification device 50, thereby causing a pressure loss of the cold air. However, when the rotation speed of the air purification device fan 43a is larger than the rotation speed of the other fan 43b, the cold air sent from the air purification device fan 43a is sufficient even if it is decelerated by the air purification device 50. Can maintain a certain pressure. Therefore, even if the air purification device 50 is provided in the duct 40, there is no significant adverse effect on the cooling performance of the refrigerator 10.

また、制御部１１が、冷蔵空間２０内の温度が所定温度よりも低い場合に、複数のファン４３のうち空気浄化装置用ファン４３ａのみが回転するよう制御する場合、冷却する必要が無い冷蔵空間２０に冷気を送るためにエネルギーが浪費されることを抑えながら空気浄化を行うことができる。   Further, when the control unit 11 controls so that only the air purification device fan 43a among the plurality of fans 43 rotates when the temperature in the refrigerated space 20 is lower than a predetermined temperature, the refrigerated space that does not need to be cooled. Air purification can be performed while suppressing waste of energy for sending cool air to 20.

上記実施形態の変更例について説明する。   A modification of the above embodiment will be described.

冷蔵空間２０への冷気の流路だけでなく、冷凍空間３０への冷気の流路にも空気浄化装置５０が設けられ、その周囲が上記実施形態と同様の構造となっていても良い。   The air purification device 50 may be provided not only in the cool air flow path to the refrigerating space 20 but also in the cool air flow path to the refrigeration space 30, and the periphery thereof may have the same structure as in the above embodiment.

また、上記実施形態では、ダクト４０内の冷気の流れ方向に対して垂直な面内に、２つのファン４３ａ、４３ｂが並べて設けられている。しかし、３つ以上のファンがダクト４０内の冷気の流れ方向に対して垂直な面内に並べて設けられていても良い。その場合も、３つ以上のファンのうち１つが、空気浄化装置用ファンとして、空気浄化装置へ送風する。   Moreover, in the said embodiment, the two fans 43a and 43b are provided side by side in the surface perpendicular | vertical with respect to the flow direction of the cool air in the duct 40. As shown in FIG. However, three or more fans may be provided side by side in a plane perpendicular to the flow direction of the cold air in the duct 40. Also in this case, one of the three or more fans sends air to the air purification device as a fan for the air purification device.

３つ以上のファンが設けられている場合において、空気浄化装置へ冷気を送る空気浄化装置用ファンの、他のファンや空気浄化装置との位置関係は、上記実施形態の場合と同じである。１つ目の例として、空気浄化装置用ファンが他のファンよりも空気浄化装置に近接している例が挙げられる。また２つ目の例として、空気浄化装置用ファンの冷気の流れの下流側の場所とその他のファンの冷気の流れの下流側の場所との間が仕切壁で仕切られ、空気浄化装置は仕切壁よりも空気浄化装置用ファン側の場所に設けられている例が挙げられる。２つ目の例において、空気浄化装置用ファンの冷気の流れの下流側の場所とその隣のファンの冷気の流れの下流側の場所とだけが仕切られていてもいいし、空気浄化装置用ファンを含む全てのファンの下流側の場所が独立するように仕切られていても良い。また３つ目の例として、３つ以上のファンが一列に並べて設けられ、その列の一端部に空気浄化装置が設けられ、同じ一端側のファンが空気浄化装置用ファンとして空気浄化装置に送風する例が挙げられる。   In the case where three or more fans are provided, the positional relationship of the fan for the air purification device that sends the cold air to the air purification device with the other fans and the air purification device is the same as in the above embodiment. As a first example, there is an example in which the air purification device fan is closer to the air purification device than the other fans. As a second example, a partition wall separates a location on the downstream side of the cool air flow of the fan for the air purification device from a location on the downstream side of the cool air flow of the other fan, and the air purification device is divided into partitions. The example provided in the place of the fan side for air purification apparatuses rather than a wall is given. In the second example, only the location on the downstream side of the cool air flow of the fan for the air purification device and the location on the downstream side of the cool air flow of the adjacent fan may be partitioned. The downstream locations of all the fans including the fans may be partitioned so as to be independent. As a third example, three or more fans are arranged in a row, an air purification device is provided at one end of the row, and a fan at the same end side blows air to the air purification device as a fan for the air purification device. An example is given.
