Description
本発明は冷蔵庫に関し、特に冷凍室の冷却構成に関するものである。 The present invention relates to a refrigerator, and more particularly to a cooling structure of a freezer compartment.
一般に冷蔵庫は、冷蔵庫本体内に冷蔵室、野菜室、冷凍室等の貯蔵室が設けてあり、前記各貯蔵室には前記冷凍室の背面部分に設けた冷却室から冷気を供給するようになっている（例えば、特許文献１参照）。 In general, refrigerators are provided with storage rooms such as a refrigerator room, a vegetable room, and a freezer room in the refrigerator body, and cold air is supplied to each of the storage rooms from a cooling room provided at the back of the freezer room. (For example, refer to Patent Document 1).
図６は特許文献１記載の冷蔵庫を示し、この冷蔵庫は冷蔵庫本体に設けた冷凍室１０１の背面に冷却室１０２が設けてあり、この冷却室１０２に配置した冷却器１０３により冷気を生成している。そして、この冷気は冷却器上部の冷気ファン１０４から冷気分配通路部１０６及び冷気通路１０５を介して冷蔵室、野菜室（いずれも図示せず）に供給しこれを冷却している。また、前記冷気分配通路部１０６の上下部には冷凍室１０１に開口させた冷気供給口１０７、１０８が設けてあり、この冷気供給口１０７、１０８を介して冷凍室１０１を冷却するようになっている。 FIG. 6 shows a refrigerator described in Patent Document 1. This refrigerator is provided with a cooling chamber 102 on the back surface of a freezing chamber 101 provided in the refrigerator body, and cool air is generated by a cooler 103 disposed in the cooling chamber 102. Yes. Then, this cold air is supplied from the cold air fan 104 at the upper part of the cooler to the refrigerating room and vegetable room (both not shown) via the cold air distribution passage part 106 and the cold air passage 105 to cool it. Further, cold air supply ports 107 and 108 opened to the freezer compartment 101 are provided at the upper and lower portions of the cold air distribution passage portion 106, and the freezer compartment 101 is cooled through the cold air supply ports 107 and 108. ing.
しかしながら、上記特許文献１に記載されている従来の冷蔵庫は、冷気分配通路部１０６に形成されている冷気供給口１０７、１０８が冷気分配通路部１０６を形成する垂直壁にそのまま形成されていて水平方向に開口しているため、冷凍室１０１内の冷却に冷却ムラが生じやすいという傾向があった。特に、冷凍室１０１は上下二段に容器を配置した形で構成してあるが、冷凍室容積の大部分を占める下段容器（図示せずに）内は冷却ムラが生じやすい傾向にあった。 However, in the conventional refrigerator described in Patent Document 1, the cold air supply ports 107 and 108 formed in the cold air distribution passage portion 106 are formed as they are on the vertical wall forming the cold air distribution passage portion 106, and are horizontal. Due to the opening in the direction, there is a tendency that uneven cooling is likely to occur in the cooling of the freezer compartment 101. In particular, the freezer compartment 101 is configured in such a manner that the containers are arranged in two upper and lower stages, but there is a tendency for uneven cooling to easily occur in the lower container (not shown) occupying most of the freezer compartment volume.
これは、下段容器に冷気を供給する下側の冷気供給口１０８が垂直壁に開口させただけのものであるため、当該冷気供給口１０８からの冷気が略水平方向に吹出されるような形となり、下段容器の前方部分には冷気が供給されるものの、空気供給口１０８直下付近の底部には冷気が供給されにくく、冷気不足を起こして冷却ムラが発生するのであった。 This is because the lower cold air supply port 108 for supplying cold air to the lower container is simply opened in the vertical wall, so that the cold air from the cold air supply port 108 is blown out in a substantially horizontal direction. Thus, although the cool air is supplied to the front portion of the lower container, the cool air is difficult to be supplied to the bottom near the air supply port 108, resulting in insufficient cooling and uneven cooling.
そのため、このような冷却ムラを解消すべく冷凍室１０１に冷気を供給する時間、すなわち冷却時間が長めになりがちであり、省エネ性に影響を与えていた。つまり、冷凍室１０１に温度ムラが発生すると、冷凍室１０１の冷えていない部分が設定温度に達するまで冷却するので、必要以上の冷却が必要となり、省エネ性に影響を与えるのであった。 For this reason, the time for supplying cold air to the freezer compartment 101 in order to eliminate such cooling unevenness, that is, the cooling time tends to be longer, which has an effect on energy saving. That is, when temperature unevenness occurs in the freezer compartment 101, the uncooled portion of the freezer compartment 101 is cooled until it reaches the set temperature, so that more than necessary cooling is required, which affects energy saving.
また、冷凍室１０１の冷却ムラにより食品の冷却スピードに差が発生し、それが食品の鮮度低下に繋がって信頼性を低下させる、ということもあった。 In addition, the cooling unevenness of the freezing chamber 101 causes a difference in the cooling speed of the food, which leads to a decrease in the freshness of the food and a decrease in reliability.
本発明はこのような点に鑑みてなしたもので、冷凍室を均一且つ迅速に冷却できるようにして省エネ性及び信頼性を向上させた冷蔵庫を提供するものである。 This invention is made | formed in view of such a point, and provides the refrigerator which improved energy-saving property and reliability so that a freezer compartment could be cooled uniformly and rapidly.
本発明は、上記目的を達成するため、冷気供給口を形成する壁面を断面略く字状に形成
し、この略く字状下端部に開口を形成して冷気供給口とした構成としてある。
In order to achieve the above object, the present invention has a configuration in which the wall surface forming the cold air supply port is formed in a substantially square shape in cross section, and an opening is formed in the substantially square lower end portion to form the cold air supply port.
これにより、冷却ファンから供給されてくる冷気は略く字状壁面の内面に沿って整流され冷凍室側に広がった後下向きに流れを変えて冷気供給口から冷凍室内に下向きに供給されるようになる。つまり、冷気供給口からの冷気は整流されて冷凍室の冷気供給口直下部分に供給され、そのまま冷凍室、すなわち下段容器内の底部に沿って前方へと拡散していくようになり、下段容器の内部全域に行き渡って迅速かつ均一に内部を冷却する。したがって、冷凍室内の冷却時間を短縮し食品鮮度の低下を防止できる。 As a result, the cold air supplied from the cooling fan is rectified along the inner surface of the substantially rectangular wall surface, spreads to the freezer compartment side, and then flows downward to be supplied downward from the cold air supply port into the freezer compartment. become. That is, the cold air from the cold air supply port is rectified and supplied to the portion immediately below the cold air supply port of the freezer compartment, and then diffuses forward along the bottom of the freezer compartment, that is, the lower vessel. Cool throughout the interior of the interior quickly and uniformly. Therefore, the cooling time in the freezer compartment can be shortened and the food freshness can be prevented from deteriorating.
本発明は、上記構成により、冷凍室内を迅速かつ均一に冷却して冷却時間の短縮と食品鮮度の低下防止を実現できるから、省エネ性及び信頼性の高い冷蔵庫とすることができる。 According to the above-described configuration, the refrigerator can be quickly and uniformly cooled to shorten the cooling time and prevent the food freshness from being reduced. Therefore, the refrigerator can have high energy saving and reliability.
第１の発明は、冷凍室と、冷凍室冷却用の冷気を生成する冷却室と、前記冷却室で生成された冷気を強制的に貯蔵室に送風する冷却ファンと、前記冷却ファンからの冷気を冷凍室に供給する通路部と、前記冷凍室と前記冷却室との間に位置して前記通路部の壁面を構成する仕切壁部材とを備え、前記仕切壁部材はその壁面を断面略く字状に形成し、この略く字状下端部に開口を形成して冷気供給口とした構成としてある。 The first invention includes a freezing room, a cooling room that generates cold air for cooling the freezing room, a cooling fan that forcibly blows the cold air generated in the cooling room to a storage room, and the cold air from the cooling fan And a partition wall member that is located between the freezer chamber and the cooling chamber and that forms a wall surface of the passage portion, and the partition wall member has a substantially cross-sectional view of the wall surface. A cold air supply port is formed by forming a letter shape and forming an opening at the lower end of the substantially square shape.
これにより、冷却ファンから供給されてくる冷気は略く字状壁面の内面に沿って整流され冷凍室側に広がった後下向きに流れを変えて冷気供給口から冷凍室内に下向きに供給されるようになる。つまり、冷気供給口からの冷気は整流されて冷凍室の冷気供給口直下部分に供給され、そのまま冷凍室、すなわち下段容器内の底部に沿って前方へと拡散していくようになり、下段容器の内部全域に行き渡って迅速かつ均一に内部を冷却する。したがって、冷凍室内の冷却時間を短縮し食品鮮度の低下を防止できる。 As a result, the cold air supplied from the cooling fan is rectified along the inner surface of the substantially rectangular wall surface, spreads to the freezer compartment side, and then flows downward to be supplied downward from the cold air supply port into the freezer compartment. become. That is, the cold air from the cold air supply port is rectified and supplied to the portion immediately below the cold air supply port of the freezer compartment, and then diffuses forward along the bottom of the freezer compartment, that is, the lower vessel. Cool throughout the interior of the interior quickly and uniformly. Therefore, the cooling time in the freezer compartment can be shortened and the food freshness can be prevented from deteriorating.
第２の発明は、第１の発明において、前記冷気供給口は冷凍室に配置した上下二段容器の下段容器の後部開口に臨ませて設けた構成としてある。 According to a second invention, in the first invention, the cold air supply port is provided so as to face the rear opening of the lower container of the upper and lower two-stage containers arranged in the freezer compartment.
これにより、冷気供給口からの冷気は冷凍室内の大部分を占める容積の大きな下段容器内に確実に供給することができ、下段容器内を効率よく迅速に均一冷却でき、省エネ性及び信頼性をさらに高めることができる。 As a result, the cold air from the cold air supply port can be reliably supplied into the large lower container that occupies most of the freezer compartment, and the lower container can be efficiently and quickly cooled uniformly, saving energy and reliability. It can be further increased.
第３の発明は、第１または第２の発明において、前記冷気供給口は、冷却ファンより下方に位置させて冷凍室の左右方向に列設するとともに、記冷却ファンの中心を基準に左右方向で、前記冷却ファン回転方向側の開口面積を他方より大きくした構成としてある。 According to a third invention, in the first or second invention, the cold air supply port is positioned below the cooling fan and arranged in the left-right direction of the freezer compartment, and the left-right direction with respect to the center of the cooling fan. Thus, the opening area on the cooling fan rotation direction side is larger than the other.
これにより、冷凍室に供給される冷気は冷凍室の左右方向でほぼ均等化することができ
、より迅速に均一冷却が可能となる。すなわち、冷却ファンの回転方向が正面から見て右回りの場合、冷却ファンより下方の冷凍室への冷気は、冷気供給口が左右同等の場合、冷凍室の左側の冷気量が多くなる。換言すると、左側のほうが右側より冷却度合いが強くなる。しかし、前記した如く冷却ファンより下方に配置した冷気供給口において、冷却ファンの回転方向側の前記冷気供給口の開口面積を他方より大きくしたことで、貯蔵室の左右の冷気量をバランスよく改善でき、温度分布の均一化を図ることができる。これにより、さらなる省エネ性及び信頼性の向上を図ることができる。
Thereby, the cold air supplied to the freezer compartment can be substantially equalized in the left-right direction of the freezer compartment, and uniform cooling can be performed more quickly. That is, when the rotation direction of the cooling fan is clockwise when viewed from the front, the amount of cold air to the freezer compartment below the cooler fan increases on the left side of the freezer compartment when the cold air supply ports are equivalent to the left and right. In other words, the degree of cooling is stronger on the left side than on the right side. However, as described above, in the cold air supply port arranged below the cooling fan, the opening area of the cold air supply port on the rotation direction side of the cooling fan is made larger than the other, thereby improving the right and left cold air amount in the storage room in a balanced manner. The temperature distribution can be made uniform. Thereby, the further energy-saving property and the improvement of reliability can be aimed at.

The cold air that has cooled the upper and lower two-stage containers 23, 24 of the freezer compartment 9 passes over the upper edge of the front opening of each container 23, 24 by natural convection, etc., and goes from the cold air return port 26 to the cooling chamber 18. It flows.
ここで、上記上下の冷気供給口３０、３１より冷凍室９に供給される冷気のうち、上部の冷気供給口３０から供給される冷気は従来と同様、略水平方向に吹出されて上段容器２３の後部開口から上段容器２３内に流れ込んで冷却するが、下部の冷却供給口３１から供給される冷気は図５の矢印で示すように仕切壁部材２８に形成した略く字状部２８ａに案内され、整流されて下段容器２４の後部開口から下向きに吹き下ろすような形で下段容器２４内に流れ込む。 Here, of the cold air supplied to the freezer compartment 9 from the upper and lower cold air supply ports 30 and 31, the cold air supplied from the upper cold air supply port 30 is blown out in a substantially horizontal direction as in the conventional case, and the upper container 23 The cooling air flows into the upper container 23 through the rear opening and cools, but the cold air supplied from the lower cooling supply port 31 is guided to a substantially square-shaped portion 28a formed in the partition wall member 28 as indicated by an arrow in FIG. Then, it is rectified and flows into the lower container 24 in such a manner that it is blown downward from the rear opening of the lower container 24.
すなわち、上記冷気供給口３１からの冷気は下段容器２４の前記冷気供給口３１直下部分となる後部底面付近に流れ込み、その勢いでそのまま底面に沿って前方へと流動拡散するようになる。 That is, the cold air from the cold air supply port 31 flows into the vicinity of the bottom of the rear portion of the lower container 24, which is directly below the cold air supply port 31, and flows and diffuses forward along the bottom surface as it is.
したがって、冷凍室内容積の大部分を占める下段容器２４内は冷気供給口３１直下部分から前方部分までの全範囲に冷気が行き渡り、ムラなく均一かつ迅速に冷却することができる。 Therefore, in the lower container 24 occupying most of the volume of the freezer compartment, the cold air spreads over the entire range from the portion immediately below the cold air supply port 31 to the front portion, and can be uniformly and quickly cooled without unevenness.
その結果、下段容器２４内に収納した食品はほぼ同じスピードで冷却でき、冷却スピードに差が生じることによって起こる食品の劣化を防止し信頼性を向上させることができる。 As a result, the food stored in the lower container 24 can be cooled at substantially the same speed, and the deterioration of the food caused by the difference in the cooling speed can be prevented and the reliability can be improved.
また、冷凍室９内を必要以上に長く冷却する必要がなくなるので、冷却効率を向上する事ができ、省エネ性を高めることができる。 Moreover, since it is not necessary to cool the inside of the freezer compartment 9 longer than necessary, the cooling efficiency can be improved and the energy saving performance can be improved.
更には、冷凍室９内で温度ムラが発生すると、局部的に結露が発生する可能性があるが、上記したように冷凍室９の温度ムラを低減することができるので、結露の発生も低減することができる。 Furthermore, if temperature unevenness occurs in the freezer compartment 9, there is a possibility that local condensation may occur. However, since the temperature unevenness of the freezer compartment 9 can be reduced as described above, the occurrence of condensation is also reduced. can do.
特に、本実施の形態では、前記下部の冷気供給口３１は複数に分けて設けてあるから、この冷気供給口３１から吹出す冷気の流速は従来に比べ早いものとなり、下段容器２４の前方部まで確実に流れる。したがって、下段容器２４内はより迅速に均一冷却することができる。 In particular, in the present embodiment, since the lower cold air supply port 31 is divided into a plurality of parts, the flow rate of the cold air blown out from the cold air supply port 31 is faster than the conventional one, and the front portion of the lower container 24 Surely flows. Therefore, the inside of the lower container 24 can be uniformly cooled more rapidly.
また、前記下部の冷気供給口３１は冷凍室９に配置した下段容器２４の後部開口に臨ませて設けてあるから、冷気供給口３１からの冷気は容積の大きな下段容器２４内に確実に供給することができ、下段容器２４内を効率よく冷却して、省エネ性及び信頼性をさらに高めることができる。 Further, since the lower cold air supply port 31 is provided facing the rear opening of the lower container 24 disposed in the freezer compartment 9, the cold air from the cold air supply port 31 is reliably supplied into the large lower container 24. The inside of the lower container 24 can be efficiently cooled to further improve energy saving and reliability.
また、この実施の形態では、前記冷却ファン２１は右回りとなっているから、前記各冷気供給口３０、３１から冷凍室９内への冷気の流れは、冷却ファン２１の回転方向側（本実施の形態では右側）から左方向に向かって流れる様になる。したがって、冷気供給口３０、３１、特に冷却ファン２１から離れている下部の冷気供給口３１の開口面積が左右同等の場合、冷凍室９すなわち下段容器２４の左側に吹出す冷気量が多くなって冷却ムラが
発生しやすくなる。
In this embodiment, since the cooling fan 21 is clockwise, the flow of the cold air from the cold air supply ports 30, 31 into the freezer compartment 9 is on the rotation direction side of the cooling fan 21 (this In the embodiment, it flows from the right side) to the left side. Therefore, when the opening areas of the cold air supply ports 30, 31, particularly the lower cold air supply port 31 that is separated from the cooling fan 21, are the same on the left and right, the amount of cold air blown to the left side of the freezer compartment 9, that is, the lower container 24, increases. Cooling unevenness is likely to occur.
しかしながら、この実施の形態では前記冷気供給口３０、３１、特に下部の冷気供給口３１の開口面積は、冷却ファン２１の中心を基準に、ファン回転方向側の冷気供給口（図４の右側の冷気供給口）の開口面積を他方より大きくしてあるから、冷却ファン２１の回転方向側の冷気量を増加することができる。 However, in this embodiment, the opening area of the cold air supply ports 30, 31, particularly the lower cold air supply port 31, is based on the center of the cooling fan 21, and the cold air supply port (on the right side of FIG. Since the opening area of the cool air supply port) is larger than the other, the amount of cool air on the rotation direction side of the cooling fan 21 can be increased.
したがって、冷却ファン２１より下方に配置した冷気供給口３０、３１からは左右ほぼ均等に冷気が供給されるようになり、冷凍室９内の冷却ムラを解消してより一層均一な冷却を実現し、温度分布の均一化を図って、省エネ性と信頼性を向上させることができる。 Therefore, the cool air is supplied from the cool air supply ports 30 and 31 disposed below the cooling fan 21 substantially uniformly on the left and right sides, and the cooling unevenness in the freezer compartment 9 is eliminated, thereby realizing more uniform cooling. The temperature distribution can be made uniform and energy saving and reliability can be improved.
また、前記冷却ファン２１の右側には戻りダクト２９が設けてあってこの戻りダクト２９部分には冷気供給口３０，３１を形成しにくいところから、戻りダクト２９の周辺部、すなわち冷却ファン２１の右側部分は冷却不足になりやすくなっている。 Further, a return duct 29 is provided on the right side of the cooling fan 21, and since the cool air supply ports 30 and 31 are not easily formed in the return duct 29, the peripheral portion of the return duct 29, that is, the cooling fan 21. The right part tends to be undercooled.
しかしながら、本実施の形態の冷蔵庫では、前記冷却ファン２１の回転方向となる右側部分の冷気供給口３０，３１（図４の右側の冷気供給口）は、前記戻りダクト２９部分に冷気供給口３０、３１を形成しにくいことを見越してその分更にその開口面積を他方より大きくしてあるから、冷却ファン２１の回転方向側の冷気量を増加し、冷却不足を解消して均一な冷却を実現することができる。すなわち、戻りダクト２９設置に伴う冷気供給口３０，３１の配置バランス不均衡を補って冷却室１８内を均一かつ迅速に冷却し、省エネ性及び信頼性を高めることができる。 However, in the refrigerator of the present embodiment, the cool air supply ports 30 and 31 (the cool air supply port on the right side in FIG. 4) in the rotation direction of the cooling fan 21 are connected to the cool air supply port 30 in the return duct 29 portion. In view of the difficulty of forming 31, the opening area is made larger than that of the other, so the amount of cool air on the rotation direction side of the cooling fan 21 is increased and the cooling shortage is eliminated to achieve uniform cooling. can do. That is, the cooling chamber 18 can be uniformly and quickly cooled by compensating for the imbalance in the arrangement of the cold air supply ports 30 and 31 associated with the installation of the return duct 29, and energy saving and reliability can be improved.
さらに、冷却ファン２１は、冷蔵庫本体１を正面より見た場合、冷凍室９の左右方向の中心垂線に対して、前記戻りダクト２９の反対側に配置したことにより、冷却器２０と冷却ファン２１の効率的配置を実現しながら、確実に冷凍室９の左右の冷却量をバランスよく改善でき、温度分布の均一化を図ることができる。同時に、前記戻りダクト２９の前面部分には冷気供給口３０、３１を設けていないので、冷気供給口３０、３１に流れる冷気の一部が冷気戻りダクト２９内の比較的温度の高い空気と熱交換して温度上昇するなどのことを防止でき、省エネ性向上を促進することができる。 Furthermore, the cooling fan 21 is disposed on the opposite side of the return duct 29 with respect to the central vertical line in the left-right direction of the freezer compartment 9 when the refrigerator main body 1 is viewed from the front. The amount of cooling on the left and right sides of the freezer compartment 9 can be improved with good balance and the temperature distribution can be made uniform. At the same time, since the cool air supply ports 30, 31 are not provided in the front portion of the return duct 29, a part of the cool air flowing through the cool air supply ports 30, 31 is relatively hot air and heat in the cool air return duct 29. It is possible to prevent the temperature from increasing due to replacement, and to promote energy saving improvement.
以上、本発明に係る冷蔵庫について、上記実施の形態を用いて説明してきたが、本発明は、これに限定されるものではなく、本発明の目的を達成する範囲内で種々変更可能であることは言うまでもない。 As mentioned above, although the refrigerator which concerns on this invention has been demonstrated using the said embodiment, this invention is not limited to this, A various change is possible within the range which achieves the objective of this invention. Needless to say.
例えば、上記実施の形態では、冷凍室９に冷気を供給する下部の冷気供給口３１のみを断面略く字状部分の下部に開口させて設けたものを例にして説明したが、これは上部の冷気供給口３０にも適用、すなわち、冷気供給口３０部分の壁面も冷凍室９側に屈曲する断面略く字状に形成して当該部分に冷気供給口３０を設けるようにしてもよいものである（なお、上段容器２３は底が浅くて容量が小さいのでこのような構成を適用するまでもない場合が多い）。 For example, in the above-described embodiment, the description has been given by taking as an example an example in which only the lower cold air supply port 31 for supplying cold air to the freezer compartment 9 is opened at the lower portion of the substantially square-shaped section. The cold air supply port 30 may also be applied, that is, the wall surface of the cold air supply port 30 may be formed in a substantially square shape that bends toward the freezer compartment 9 and the cold air supply port 30 may be provided in that portion. (In addition, since the upper container 23 has a shallow bottom and a small capacity, there is often no need to apply such a configuration).
また、冷却ファン２１を本体の中心から左側にずらせ、戻りダクト２９を冷却ファン２１の一側、すなわち右側に設けた冷蔵庫を例にして説明したが、これは冷却ファン２１を右側にずらせてその左側に戻りダクト２９を設ける、或いは、冷却ファン２１を中心に設けてその両側に戻りダクト２９を設けるなどしてもよいものである。そして、その場合は、冷却ファン２１からの冷気の流れに基づき冷気供給口３０，３１からの冷気量を考慮してその開口面積を設定すればよい。一例として冷却ファン２１を中心に設けてその両側に戻りダクト２９を設けた場合は、冷却ファン２１の回転方向側の冷気供給口３０，３１の開口面積を他方より大きく（回転方向が右側であれば右側の開口面積を大きくし、左側で
あれば左側の開口面積を大きく）すればよい。
In addition, the cooling fan 21 is shifted to the left side from the center of the main body and the return duct 29 is described as an example of the refrigerator provided on one side of the cooling fan 21, that is, the right side. However, this is because the cooling fan 21 is shifted to the right side. The return duct 29 may be provided on the left side, or the cooling fan 21 may be provided in the center and the return duct 29 may be provided on both sides thereof. In that case, the opening area may be set in consideration of the amount of cold air from the cold air supply ports 30 and 31 based on the flow of cold air from the cooling fan 21. As an example, when the cooling fan 21 is provided at the center and the return ducts 29 are provided on both sides thereof, the opening area of the cooling air supply ports 30 and 31 on the rotation direction side of the cooling fan 21 is larger than the other (the rotation direction should be on the right side). For example, the opening area on the right side may be increased and the opening area on the left side may be increased on the left side).
このように、今回開示した実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。つまり、本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれることが意図される。 Thus, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. That is, the scope of the present invention is shown not by the above description but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.
以上のように本発明は、冷凍室内を迅速かつ均一に冷却して冷却時間の短縮と食品鮮度の低下防止を実現できるから、省エネ性及び信頼性の高い冷蔵庫とすることができる。よって、家庭用冷蔵庫をはじめとして業務用冷蔵庫、ショーケースなど他の冷凍冷蔵応用商品にも広く適用できる。 As described above, the present invention can quickly and uniformly cool the inside of the freezer to reduce the cooling time and prevent the food freshness from being lowered. Therefore, the refrigerator can have high energy saving and high reliability. Therefore, it can be widely applied to other refrigerator-freezing applied products such as a home refrigerator, a commercial refrigerator, and a showcase.
