Description

本発明は、システムキッチンなどのカウンターに組み込まれる冷蔵庫であって、特に、引出し式食品収納部を有する冷蔵庫に関するものである。   The present invention relates to a refrigerator incorporated in a counter such as a system kitchen, and more particularly to a refrigerator having a drawer type food storage unit.

システムキッチンなどのカウンターに組み込まれる冷蔵庫（いわゆるアンダーカウンター冷蔵庫）として、回転扉式の小型冷蔵庫に加えて、引出し式食品収納部を有する冷蔵庫が提案されている（例えば、特許文献１参照）。これは、家庭用大型冷蔵庫と同様に、引出し式食品収納部は冷凍食品や野菜、飲料用ビンやペットボトルを出し入れする際の利便性が高いためである。   As a refrigerator incorporated in a counter such as a system kitchen (a so-called undercounter refrigerator), a refrigerator having a drawer type food storage unit in addition to a rotary door type small refrigerator has been proposed (for example, see Patent Document 1). This is because, like a large refrigerator for home use, the drawer-type food storage unit is highly convenient for taking in and out frozen foods and vegetables, beverage bottles and plastic bottles.

しかしながら、アンダーカウンター冷蔵庫は、カウンターの構造体に組み込まれて使用されることから、外形寸法や放熱経路に制約がある点で通常の家庭用冷蔵庫とは異なる設計が必要となる。   However, since the undercounter refrigerator is used by being incorporated in the structure of the counter, a design different from that of a normal household refrigerator is required in that there are restrictions on the external dimensions and the heat dissipation path.

以下、図面を参照しながら従来の冷蔵庫を説明する。   Hereinafter, a conventional refrigerator will be described with reference to the drawings.

図２は従来の冷蔵庫の縦断面図である。   FIG. 2 is a longitudinal sectional view of a conventional refrigerator.

図２において、天板５１はシステムキッチンのカウンターを構成するものであり、天板５１の下に冷蔵庫５２が設置される。冷蔵庫５２は、食品収納室を構成する断熱筐体５３と、断熱扉５４、引出し式収納部５５、引出し式収納部５５を冷却する蒸発器５６、蒸発器５６の除霜水を排水するための水受け５７を有している。ここで、引出し式収納部５５は断熱扉５４と一体で、レール部材（図示せず）を介して断熱筐体５３に取り付けられ、冷蔵庫５２から引き出して食品の出し入れを行うことができる。また、蒸発器５６は、引出し式収納部５５の上部に横置きに取り付けられ、自然対流あるいは循環ファン（図示せず）による強制対流によって、引出し式収納部５５を冷却する。蒸発器５６を引出し式収納部５５の上部に取り付ける理由は、循環ファン（図示せず）の停止中でも自然対流による冷却が可能であるとともに、蒸発器５６をヒータ（図示せず）で加熱して除霜する際に発生する暖気が、引出し式収納部５５を加熱することを防ぐためである。また、断熱筐体５３の背面側に蒸発器５６を縦置きすると、引出し式収納部５５の奥行き寸法が制限されて、食品収納空間が減少する問題がある。   In FIG. 2, a top plate 51 constitutes a counter of the system kitchen, and a refrigerator 52 is installed under the top plate 51. The refrigerator 52 includes a heat insulating casing 53 that constitutes a food storage room, a heat insulating door 54, a drawer type storage unit 55, an evaporator 56 that cools the drawer type storage unit 55, and drainage of defrost water from the evaporator 56. A water receiver 57 is provided. Here, the drawer-type storage unit 55 is integrated with the heat insulating door 54 and is attached to the heat insulating casing 53 via a rail member (not shown), and can be pulled out of the refrigerator 52 to take in and out food. Further, the evaporator 56 is mounted horizontally on the upper part of the drawer type storage unit 55 and cools the drawer type storage unit 55 by natural convection or forced convection by a circulation fan (not shown). The reason why the evaporator 56 is attached to the upper part of the drawer-type storage 55 is that cooling by natural convection is possible even when the circulation fan (not shown) is stopped, and the evaporator 56 is heated by a heater (not shown). This is because warm air generated when defrosting prevents the drawer-type storage unit 55 from being heated. In addition, when the evaporator 56 is placed vertically on the back side of the heat insulating casing 53, there is a problem that the depth size of the drawer-type storage unit 55 is limited and the food storage space is reduced.

また、断熱筐体５３の下部に機械室６０を有し、機械室６０内に凝縮器６１、蒸発皿６２、機械室ファン６３、圧縮機６４を収納している。ここで、蒸発皿６２は、水受け５７を介して、蒸発器５６の除霜水を一旦回収し、機械室６０内部の排熱で蒸発させるものである。また、機械室ファン６３は、冷蔵庫５２下部に形成された吸気ダクト６５を介して、冷蔵庫５２前面下部の空気を吸入して機械室６０内を冷却し、その排熱を排気口６６から排出するものである。ここで、凝縮器６１は圧縮機６４の風上側に縦置きに設置され、機械室ファン６３により吸気ダクト６５を介して供給される外部空気によって冷却される。凝縮器６１を圧縮機６４の風上側に縦置きに設置する理由は、より温度の低い空気を凝縮器６１のより広い前面開口部に供給することで、放熱効率を向上するためである。また、前面開口部の面積が広いほど、外部空気に含まれる埃が付着して性能低下する影響が小さくなるので、耐久性にも優れた構成である。   In addition, the machine room 60 is provided in the lower part of the heat insulating casing 53, and the condenser 61, the evaporating dish 62, the machine room fan 63, and the compressor 64 are accommodated in the machine room 60. Here, the evaporating dish 62 temporarily collects defrosted water from the evaporator 56 via the water receiver 57 and evaporates it with exhaust heat inside the machine room 60. The machine room fan 63 sucks air in the lower front of the refrigerator 52 through the intake duct 65 formed in the lower part of the refrigerator 52 to cool the inside of the machine room 60 and discharges the exhaust heat from the exhaust port 66. Is. Here, the condenser 61 is installed vertically on the windward side of the compressor 64, and is cooled by external air supplied by the machine room fan 63 via the intake duct 65. The reason why the condenser 61 is installed vertically on the windward side of the compressor 64 is to improve the heat radiation efficiency by supplying air having a lower temperature to the wider front opening of the condenser 61. Further, the larger the area of the front opening is, the smaller the influence of the dust contained in the external air adhering to the performance deterioration becomes, so that the configuration is excellent in durability.

以上のように構成された従来の冷蔵庫の冷凍サイクルについて以下にその動作を説明する。   The operation of the refrigeration cycle of the conventional refrigerator configured as described above will be described below.

冷蔵庫５２を冷却する冷凍サイクルは、圧縮機６４、凝縮器６１、機械室ファン６３、蒸発器５６からなる。圧縮機６４を駆動すると、圧縮機６４で圧縮された冷媒は、凝縮器６１で放熱しながら液化し、膨張機構（図示せず）を介して蒸発器５６で蒸発しながら吸熱した後、再び圧縮機６４へ還流する。そして、引出し式収納部５５が所定の温度以下になると、この冷凍サイクルを停止し、引出し式収納部５５が所定の温度を越えると、この冷凍サイクルを再び稼動する。この結果、引出し式収納部５５の温度を所定の範囲に保つものである。   The refrigeration cycle for cooling the refrigerator 52 includes a compressor 64, a condenser 61, a machine room fan 63, and an evaporator 56. When the compressor 64 is driven, the refrigerant compressed by the compressor 64 is liquefied while dissipating heat in the condenser 61, absorbs heat while evaporating in the evaporator 56 via an expansion mechanism (not shown), and then compressed again. Reflux to machine 64. When the drawer-type storage unit 55 becomes a predetermined temperature or lower, the refrigeration cycle is stopped. When the drawer-type storage unit 55 exceeds a predetermined temperature, the refrigeration cycle is operated again. As a result, the temperature of the drawer-type storage unit 55 is maintained within a predetermined range.

しかしながら、従来の冷蔵庫の構成では、機械室６０の前方の空間を有効利用することが難しく、機械室６０の上部にある引出し式収納部５５の高さを確保すると、結果として冷蔵庫５２の高さ寸法が大きくなり、カウンターの天板５１に加熱調理器などの他の機器を設置することが困難となる。一方、家庭用冷蔵庫などと同様に、蒸発器５６や機械室６０を冷蔵庫５２の背面側に集約すると、奥行きに制約があるキッチンカウンターに収納するために引出し式収納部５５の奥行きが十分確保できない問題が生じる。また、排気口６６が吸気ダクト６５に近く、排熱が循環して十分な放熱性能が得られない懸念がある。   However, in the conventional refrigerator configuration, it is difficult to effectively use the space in front of the machine room 60. If the height of the drawer-type storage unit 55 at the upper part of the machine room 60 is secured, the height of the refrigerator 52 is consequently obtained. The size becomes large, and it becomes difficult to install other devices such as a heating cooker on the top plate 51 of the counter. On the other hand, when the evaporator 56 and the machine room 60 are gathered on the rear side of the refrigerator 52 as in the case of a household refrigerator, the drawer-type storage unit 55 cannot be sufficiently deep because it is stored in a kitchen counter with limited depth. Problems arise. Further, there is a concern that the exhaust port 66 is close to the intake duct 65 and the exhaust heat is circulated, so that sufficient heat radiation performance cannot be obtained.

本発明は、従来の課題を解決するもので、引出し式収納部の高さと奥行きを十分に確保しながら、加熱調理器などの他の発熱する機器と併用設置することを目的とする。   An object of the present invention is to solve the conventional problems and to be installed together with other heat-generating devices such as a heating cooker while sufficiently securing the height and depth of the drawer-type storage unit.

従来の課題を解決するために、本発明の冷蔵庫は、少なくとも圧縮機、蒸発器、凝縮器を有する冷凍サイクルを備え、断熱筐体と、前記断熱筐体の上部に配置された引出し式収納部と、前記断熱筐体の下部に横置きに設置された蒸発器と、前記蒸発器の下方に横置きに設置された凝縮器と、前記凝縮器の後方に設置された圧縮機を有するとともに、前記蒸発器を収納する冷却室と、前記冷却室内に設置され、前記蒸発器を挟む位置に少なくとも１対の対流防止リブを有するものである。 In order to solve the conventional problems, a refrigerator according to the present invention includes a refrigeration cycle including at least a compressor, an evaporator, and a condenser, and includes a heat-insulating housing and a drawer-type storage unit disposed above the heat-insulating housing. When, that Yusuke an evaporator disposed transversely in the lower part of the heat insulating housing, and a condenser disposed transversely below the evaporator, the installed compressor in the rear of the condenser A cooling chamber that houses the evaporator, and at least one pair of convection prevention ribs that are installed in the cooling chamber and sandwich the evaporator .

これによって、冷蔵庫の高さを低くするとともに、収納する食品の取り出し易さを損なわない床面からの位置に引出し式収納部を配置することができる。   Thereby, while making the height of a refrigerator low, the drawer-type storage part can be arrange | positioned in the position from the floor surface which does not impair the ease of taking out the foodstuff to store.

本発明の冷蔵庫は、機械室の前面を有効利用することで引出し式収納部の高さを確保しながら、カウンターの天板に加熱調理器などの他の発熱する機器を設置可能とするとともに、冷蔵庫の最上部に引出し式収納部を配置することで、収納する食品の取り出し易さを維持することができる。   The refrigerator of the present invention enables the installation of other heat-generating equipment such as a heating cooker on the top plate of the counter while ensuring the height of the drawer-type storage unit by effectively using the front of the machine room. By arranging the drawer-type storage unit at the top of the refrigerator, it is possible to maintain the ease of taking out the food to be stored.

これによって、冷凍サイクル構成部品を冷蔵庫下部に集約することができ、冷蔵庫の高さを低くするとともに、冷蔵庫の最上部に引出し式収納部を配置することで、収納する食品の取り出し易さを損なわない床面からの高さを維持することができる。   As a result, the components of the refrigeration cycle can be concentrated in the lower part of the refrigerator, the height of the refrigerator is lowered, and the ease of taking out the food to be stored is impaired by arranging the drawer-type storage unit at the top of the refrigerator. No height from the floor can be maintained.

これによって、蒸発器を除霜中に暖められた冷却室内の空気が自然対流によって上昇することを抑制し、引出し式収納部の温度上昇を抑えることができる。   Thereby, it is possible to suppress the air in the cooling chamber warmed during the defrosting of the evaporator from rising due to natural convection, and to suppress the temperature rise of the drawer-type storage unit.

The present invention is not limited to the embodiments.

（実施の形態１）
図１は本発明の実施の形態における冷蔵庫の縦断面図である。 (Embodiment 1)
FIG. 1 is a longitudinal sectional view of a refrigerator in an embodiment of the present invention.

図１において、天板１１はシステムキッチンのカウンターを構成するものであり、天板１１の下に加熱調理器１２と、加熱調理器１２の操作部１３、冷蔵庫１４が設置される。冷蔵庫１４は、食品収納室を構成する断熱筐体１５と、断熱扉１６、断熱筐体１５の上部に配置された引出し式収納部１７、断熱筐体１５の下部に形成された冷却室２０を有している。ここで、引出し式収納部１７は断熱扉１６と一体で、レール部材（図示せず）を介して断熱筐体１５に取り付けられ、冷蔵庫１４から引き出して食品の出し入れを行うことができる。   In FIG. 1, the top plate 11 constitutes a counter of the system kitchen, and a heating cooker 12, an operation unit 13 of the heating cooker 12, and a refrigerator 14 are installed under the top plate 11. The refrigerator 14 includes a heat insulating casing 15 that constitutes a food storage chamber, a heat insulating door 16, a drawer-type storage portion 17 disposed at the top of the heat insulating casing 15, and a cooling chamber 20 formed at the bottom of the heat insulating casing 15.

Here, the drawer-type storage unit 17 is integral with the heat insulating door 16 and is attached to the heat insulating housing 15 via a rail member (not shown), and can be pulled out of the refrigerator 14 to take in and out food.

冷却室２０には、蒸発器２１と、蒸発器２１で生成された冷気を送風する蒸発器ファン２２、冷却室２０を前方と後方に隔てるとともに蒸発器ファン２２を固定するファンリング２３、蒸発器２１を挟むように形成された一対の対流防止リブ２４を収納している。また、断熱筐体１５内部の空気を循環するために、冷却室２０の上部に吸入口２５と吹出口
２６を形成するとともに、蒸発器２１の除霜水を排水するために、冷却室２０の下部に水受け２７を形成している。また、ファンリング２３よりも前方の結露水を水受け２７へ排水するために、ファンリング２３に連通口２８を形成している。 The cooling chamber 20 includes an evaporator 21, an evaporator fan 22 that blows the cool air generated by the evaporator 21, a fan ring 23 that separates the cooling chamber 20 forward and backward, and fixes the evaporator fan 22, an evaporator A pair of convection prevention ribs 24 formed so as to sandwich 21 are housed. In addition, in order to circulate the air inside the heat insulating housing 15, an inlet 25 and an outlet 26 are formed in the upper part of the cooling chamber 20, and in order to drain defrost water from the evaporator 21, A water receiver 27 is formed in the lower part. In addition, a communication port 28 is formed in the fan ring 23 in order to drain condensed water ahead of the fan ring 23 to the water receiver 27.

ここで、蒸発器２１は、冷却室２０に横置きに設置され、蒸発器ファン２２による強制対流によって断熱筐体１５内部の空気を循環しながら冷却する。また、蒸発器２１及び蒸発器ファン２２、ファンリング２３、水受け２７は、ヒータ（図示せず）によって除霜され、その際に発生する暖気は一対の対流防止リブ２４によって捕らえられ、冷却室２０から引出し式収納部１７の周辺に流出することを防止する。また、蒸発器ファン２２は、前方の対流防止リブ２４と水受け２７の間に、前傾して設置され、除霜の際に水受け２７で発生する暖気が蒸発器ファン２２を通過して結露することを防止している。   Here, the evaporator 21 is installed horizontally in the cooling chamber 20, and cools while circulating the air inside the heat insulating casing 15 by forced convection by the evaporator fan 22. The evaporator 21, the evaporator fan 22, the fan ring 23, and the water receiver 27 are defrosted by a heater (not shown), and the warm air generated at that time is captured by the pair of convection prevention ribs 24, and the cooling chamber 20 is prevented from flowing out to the periphery of the drawer-type storage unit 17. The evaporator fan 22 is installed between the front convection prevention rib 24 and the water receiver 27 so as to be inclined forward, and warm air generated in the water receiver 27 during defrosting passes through the evaporator fan 22.

The machine room fan 33 allows the air in the lower front of the refrigerator 14 to be sucked into the front air inlet 35 and the lower air inlet. The air is sucked from the port 36 and the exhaust heat is discharged from the exhaust port 37.

ここで、凝縮器３１は圧縮機３４の風上に横置きされ、機械室ファン３３により供給される外部空気によって冷却される。この構成によって、機械室３０の前部の高さを抑制しながら、機械室３０前部の空間を有効利用できる。なお、凝縮器３１の埃付着による性能低下を抑制するため、機械室３０前方に前部吸気口３５と下部吸気口３６の両方を設けることが望ましい。また、凝縮器３１の性能低下を抑制するために、下部吸気口３６は横置きされた凝縮器３１の下面の１／２以下の面積として、前方側に設けることが望ましい。   Here, the condenser 31 is placed horizontally on the wind of the compressor 34 and cooled by the external air supplied by the machine room fan 33. With this configuration, it is possible to effectively use the space in the front part of the machine room 30 while suppressing the height of the front part of the machine room 30. It is desirable to provide both the front air inlet 35 and the lower air inlet 36 in front of the machine room 30 in order to suppress the performance deterioration due to dust adhering to the condenser 31. Moreover, in order to suppress the performance fall of the condenser 31, it is desirable to provide the lower inlet 36 in the front side as an area of 1/2 or less of the lower surface of the horizontally placed condenser 31.

また、冷蔵庫１４は、背面に背面ダクト３８、天面に天面ダクト３９を有し、排気口３７から排出された空気は、背面ダクト３８と天面ダクト３９を介して、冷蔵庫１４の前面上部へ排出される。また、加熱調理器１２はコイルの電磁誘導を用いて加熱する調理器であって、冷蔵庫１４とは独立に動作し、内部に設置された冷却ファン（図示せず）によって、吸気口４０から吸入された空気によってその内部を冷却するとともに、排気口４１から排熱する。ここで、加熱調理器１２内部を冷却する風路は、天面ダクト３９から並列分岐している。 この構成によって、機械室３０の排熱が再び前部吸気口３５や下部吸気口３６から吸気されることを防止するとともに、冷蔵庫１４の上部に設置された加熱調理器１２は、機械室ファン３３が停止した状態においても冷蔵庫１４と独立して内部を冷却することができる。加熱調理器１２が機械室ファン３３の停止中でも冷却できる理由は、機械室３０の後部に設置された圧縮機３４が停止中でも外部空気より温度が高く、下部吸気口３６から排気口３７に向けて自然対流が発生し背面ダクト３８内部に上昇流が形成されるためである。   Further, the refrigerator 14 has a rear duct 38 on the back surface and a top surface duct 39 on the top surface, and the air discharged from the exhaust port 37 passes through the rear duct 38 and the top surface duct 39 to the upper front portion of the refrigerator 14. Is discharged. The heating cooker 12 is a cooker that uses electromagnetic induction of a coil, and operates independently of the refrigerator 14 and is sucked from the intake port 40 by a cooling fan (not shown) installed therein. The inside of the air is cooled by the generated air and exhausted from the exhaust port 41. Here, the air path for cooling the inside of the heating cooker 12 branches in parallel from the top duct 39. With this configuration, the exhaust heat of the machine room 30 is prevented from being sucked again from the front air inlet 35 and the lower air inlet 36, and the heating cooker 12 installed at the upper part of the refrigerator 14 is provided with the machine room fan 33. Even in the state where is stopped, the inside can be cooled independently of the refrigerator 14. The reason why the heating cooker 12 can be cooled even when the machine room fan 33 is stopped is that the temperature of the compressor 34 installed at the rear of the machine room 30 is higher than that of the external air even when the compressor 34 is stopped. This is because natural convection occurs and an upward flow is formed inside the rear duct 38.

以上のように構成された本発明の実施の形態における冷蔵庫の冷凍サイクルについて以下にその動作を説明する。   The operation of the refrigeration cycle of the refrigerator according to the embodiment of the present invention configured as described above will be described below.

冷蔵庫１４を冷却する冷凍サイクルは、圧縮機３４、凝縮器３１、機械室ファン３３、蒸発器２１、蒸発器ファン２２からなる。圧縮機３４を駆動すると、圧縮機３４で圧縮された冷媒は、凝縮器３１で放熱しながら液化し、膨張機構（図示せず）を介して蒸発器２１で蒸発しながら吸熱した後、再び圧縮機３４へ還流する。このとき、圧縮機３４と同期して機械室ファン３３を駆動して、前部吸気口３５と下部吸気口３６から外部空気を流入することで、凝縮器３１と圧縮機３４を冷却するとともに、その排熱を流入した空気とともに排気口３７から排出し、背面ダクト３８と天面ダクト３９を介して外部へ還流する。
また、圧縮機３４と同期して蒸発器ファン２２を駆動して、吸入口２５から断熱筐体１５内部の空気を吸入し、蒸発器２１と熱交換して温度が低下した空気を吹出口２６から吹出して断熱筐体１５内部へ還流する。引出し式収納部１７及び収納された食品は、吹出口２６から吹出す冷気によって冷却される。 The refrigeration cycle for cooling the refrigerator 14 includes a compressor 34, a condenser 31, a machine room fan 33, an evaporator 21, and an evaporator fan 22. When the compressor 34 is driven, the refrigerant compressed by the compressor 34 is liquefied while dissipating heat in the condenser 31 and absorbs heat while evaporating in the evaporator 21 via an expansion mechanism (not shown), and then compressed again. Reflux to machine 34. At this time, the condenser 31 and the compressor 34 are cooled by driving the machine room fan 33 in synchronization with the compressor 34 and flowing in external air from the front intake port 35 and the lower intake port 36. The exhaust heat is discharged from the exhaust port 37 together with the air that has flowed in, and is returned to the outside through the rear duct 38 and the top duct 39.
In addition, the evaporator fan 22 is driven in synchronization with the compressor 34, the air inside the heat insulating housing 15 is sucked from the suction port 25, and the air whose temperature has decreased due to heat exchange with the evaporator 21 is blown out. It blows out from the inside and returns to the inside of the heat insulating casing 15. The drawer-type storage unit 17 and the stored food are cooled by the cold air blown out from the air outlet 26.

そして、温度計測器（図示せず）によって計測される引出し式収納部１７の温度が所定の温度以下になると、圧縮機３４、機械室ファン３３、蒸発器ファン２２を停止することでこの冷凍サイクルを停止し、引出し式収納部１７が所定の温度を越えると、この冷凍サイクルを再び稼動する。この結果、引出し式収納部１７の温度を、冷蔵設定では０〜１０℃、冷凍設定では−１６〜−２５℃の所定の範囲に保つものである。   When the temperature of the drawer-type storage unit 17 measured by a temperature measuring device (not shown) becomes equal to or lower than a predetermined temperature, the refrigeration cycle is stopped by stopping the compressor 34, the machine room fan 33, and the evaporator fan 22. When the drawer type storage unit 17 exceeds a predetermined temperature, the refrigeration cycle is started again. As a result, the temperature of the drawer-type storage unit 17 is maintained within a predetermined range of 0 to 10 ° C. in the refrigeration setting and −16 to −25 ° C. in the freezing setting.

また、所定時間毎に、冷凍サイクルを停止した後、電気ヒータ（図示せず）に通電して、蒸発器２１、蒸発器ファン２２、ファンリング２３、水受け２７の除霜を実施する。この時、温度計測器（図示せず）によって計測される蒸発器２１の温度が５〜１０℃の所定の温度に達した時点で電気ヒータ（図示せず）の通電を停止し、除霜を終了した後、再び冷凍サイクルを稼動して引出し式収納部１７の冷却を開始する。   In addition, after the refrigeration cycle is stopped every predetermined time, an electric heater (not shown) is energized to defrost the evaporator 21, the evaporator fan 22, the fan ring 23, and the water receiver 27. At this time, when the temperature of the evaporator 21 measured by a temperature measuring instrument (not shown) reaches a predetermined temperature of 5 to 10 ° C., the electric heater (not shown) is deenergized and defrosted. After the completion, the refrigeration cycle is operated again to start cooling the drawer-type storage unit 17.

以上のように、本発明の実施の形態の冷蔵庫は、冷凍サイクル構成部品を冷蔵庫下部に集約することによって、引出し式収納部の高さを維持しながら冷蔵庫の高さを低くするとともに、収納する食品の取り出し易さを損なわない床面からの位置に引出し式収納部を配置することができる。   As described above, the refrigerator according to the embodiment of the present invention collects the refrigeration cycle components at the lower part of the refrigerator, thereby reducing the height of the refrigerator while maintaining the height of the drawer-type storage unit and storing the refrigerator. The drawer-type storage unit can be arranged at a position from the floor that does not impair the ease of taking out the food.

なお、本発明の実施の形態の冷蔵庫は、断熱筐体と断熱扉のシール部から流入する侵入熱の影響を抑えるために、冷却室の前方に吸入口、後方に吹出口として、断熱筐体内部の背面側に冷気を吹出したが、冷却室の構成を水平方向に回転して断熱筐体内部の側面方向あるいは断熱扉方向に冷気を吹出してもよい。   Note that the refrigerator according to the embodiment of the present invention has a heat-insulating housing that serves as a suction port in front of the cooling chamber and a blow-out port in the rear in order to suppress the influence of intrusion heat flowing from the sealing portion of the heat-insulating housing and the heat-insulating door Although the cool air is blown out to the back side of the inside, the structure of the cooling chamber may be rotated in the horizontal direction and the cool air may be blown out toward the side surface inside the heat insulating casing or the heat insulating door.

なお、本発明の実施の形態の冷蔵庫は、システムキッチンなどのカウンターに組み込まれることを前提に、冷蔵庫の外郭とカウンター構造体や壁との隙間を用いて背面ダクトや天面ダクトを形成したが、別体で形成した背面ダクトや天面ダクトを冷蔵庫の外郭に取り付けてもよい。   In addition, although the refrigerator of the embodiment of the present invention is built into a counter such as a system kitchen, the rear duct and the top duct are formed using the gap between the refrigerator outer shell and the counter structure or wall. A rear duct or a top duct formed separately may be attached to the outer shell of the refrigerator.

以上のように、本発明にかかる冷蔵庫は、冷凍サイクル構成部品を冷蔵庫下部に集約することによって、冷蔵庫の高さを低くするとともに、冷蔵庫の最上部に引出し式収納部を配置することで、収納する食品の取り出し易さを損なわない床面からの高さを維持することができるので、業務用冷蔵庫など他の冷凍冷蔵応用商品にも適用できる。   As described above, the refrigerator according to the present invention reduces the height of the refrigerator by consolidating the refrigeration cycle components at the lower part of the refrigerator, and stores the drawer-type storage unit at the top of the refrigerator. Since the height from the floor surface that does not impair the ease of taking out the food to be maintained can be maintained, it can be applied to other frozen and refrigerated products such as commercial refrigerators.
