Description

本発明は、圧縮機を天面後方に載置した冷蔵庫に関するものである。   The present invention relates to a refrigerator in which a compressor is placed behind the top surface.

近年、冷蔵庫は地球環境保護の観点から更なる省エネルギー化が進むとともに、小さく置けて大きく使える、いわば省スペースで大容量、さらにその使い勝手や収納性の向上が求められている。   In recent years, refrigerators have become more energy-saving from the viewpoint of protecting the global environment, and are required to be small and can be used in large quantities, so to speak, space-saving, large capacity, and improved usability and storage.

従来技術には、小さく置けて大きくつかえる冷蔵庫を実現するために、凝縮器としての配管を断熱箱体の内部に配置させることで、収納容積に影響を与えないスペースをうまく活用する形態がある（例えば、特許文献１参照）。   In the prior art, in order to realize a refrigerator that can be placed small and large, a pipe that serves as a condenser is arranged inside the heat insulation box, thereby effectively utilizing the space that does not affect the storage volume ( For example, see Patent Document 1).

図９、図１０で示すように、冷蔵庫本体１は外箱２と、内箱３と、これら両者間に充填された発泡断熱材４等で構成され、同本体１の底部に機械室８を設け、同機械室８内に圧縮機９と、同圧縮機９から発生する熱を放熱する送風機１０を配設し、機械室８の後面をカバー１５により被っていた。   As shown in FIGS. 9 and 10, the refrigerator main body 1 is composed of an outer box 2, an inner box 3, a foam heat insulating material 4 filled between the two, and a machine room 8 is provided at the bottom of the main body 1. The compressor 9 and the blower 10 that dissipates heat generated from the compressor 9 are disposed in the machine room 8, and the rear surface of the machine room 8 is covered with the cover 15.

また、内箱３内背面に冷却器室５を設け、同冷却器室５内に冷気を生成する冷却器６と、生成した冷気を強制循環する送風機７を配設し、圧縮機９の吐出側と冷却器６の入口との間に凝縮器を兼ねた放熱パイプ１１、キャピラリチューブ１２を順次直列に接続して構成した高圧側配管を接続し、冷却器６の出口と圧縮機９の吸入側との間に、キャピラリチューブ１２を添設するサクションパイプ１３を直列に接続して構成した低圧側配管を接続している。なお、前記凝縮器を兼ねた放熱パイプ１１は、冷蔵庫本体１背面の発泡断熱材４の中に埋設されている。   In addition, a cooler chamber 5 is provided on the back of the inner box 3, a cooler 6 that generates cool air in the cooler chamber 5, and a blower 7 that forcibly circulates the generated cool air are disposed, and the discharge of the compressor 9 A high-pressure side pipe constructed by connecting serially a heat radiating pipe 11 that also serves as a condenser and a capillary tube 12 is connected between the side and the inlet of the cooler 6, and the outlet of the cooler 6 and the suction of the compressor 9 are connected. A low-pressure side pipe constituted by connecting a suction pipe 13 provided with a capillary tube 12 in series is connected to the side. The heat radiating pipe 11 also serving as the condenser is embedded in the foam heat insulating material 4 on the back of the refrigerator body 1.

図１１はその冷凍サイクルを図に表したものであり、圧縮機９、放熱パイプ１１、キャピラリチューブ１２、冷却器６がサクションパイプ１３によって順次連結され環状の閉回路を形成されている。   FIG. 11 shows the refrigeration cycle. The compressor 9, the heat radiating pipe 11, the capillary tube 12, and the cooler 6 are sequentially connected by a suction pipe 13 to form an annular closed circuit.

上記構成において、冷却器６を通過した冷媒が圧縮機９において圧縮され、高温、高圧のガス状冷媒となる。このガス状冷媒が放熱パイプ１１により放熱し、中温、高圧の液状冷媒となる。続いて、この液状冷媒はキャピラリチューブ１２により減圧された後、冷却器６を通過しながら蒸発し、低温、低圧の冷媒ガスとなり、各区画室における熱交換機能を成している。この後、冷媒はガス状態で再び圧縮機９に吸入されることにより冷凍サイクルを完了するよう構成されている。
特開２００２−３６４９７５号公報 In the above configuration, the refrigerant that has passed through the cooler 6 is compressed by the compressor 9 and becomes a high-temperature, high-pressure gaseous refrigerant. This gaseous refrigerant dissipates heat through the heat radiating pipe 11 and becomes a medium-temperature, high-pressure liquid refrigerant. Subsequently, the liquid refrigerant is depressurized by the capillary tube 12 and then evaporated while passing through the cooler 6 to become a low-temperature and low-pressure refrigerant gas, thereby forming a heat exchange function in each compartment. Thereafter, the refrigerant is sucked into the compressor 9 again in a gas state, thereby completing the refrigeration cycle.

このような冷蔵庫には、図３のように冷凍サイクルが設けられ、圧縮機５２内に封入された冷媒が冷凍サイクルを循環するよう構成される。以下、その冷凍サイクルについて説明する。   Such a refrigerator is provided with a refrigeration cycle as shown in FIG. 3, and is configured such that the refrigerant sealed in the compressor 52 circulates in the refrigeration cycle. Hereinafter, the refrigeration cycle will be described.

冷凍サイクルは、その全てが密閉空間で構成され、封入された冷媒を圧縮し冷凍サイクルへ高温高圧の冷媒を送り出す圧縮機５２、冷媒を放熱し中温高圧に凝縮液化させる凝縮器９１、ゴミや金属粉等を圧縮機５２へ戻さないための図示しないフィルターや、システム内の水分を吸着する図示しない吸着部材などを備えたドライヤ１０８、液化冷媒を減圧させる減圧装置１０９、冷媒を蒸発させて冷熱を発生させる蒸発器８３、蒸発器８３で気化した冷媒を圧縮機５２へと戻すための吸入配管１１０などから構成されて、それぞれが冷媒配管１１１により接続されている。   The refrigeration cycle is entirely composed of a sealed space, compresses the enclosed refrigerant and sends out the high-temperature and high-pressure refrigerant to the refrigeration cycle, the condenser 91 that dissipates the refrigerant and condenses and liquefies it to medium temperature and high pressure, dust and metal Dryer 108 equipped with a filter (not shown) for preventing powder or the like from returning to the compressor 52, a suction member (not shown) for adsorbing moisture in the system, a decompression device 109 for decompressing the liquefied refrigerant, and evaporating the refrigerant The evaporator 83 to be generated and the suction pipe 110 for returning the refrigerant vaporized by the evaporator 83 to the compressor 52 are connected to each other by the refrigerant pipe 111.

ここで圧縮機５２は、断熱箱体３１の天面部に背面側を一段低い段差状に窪ませた凹部５０に載置される。凹部５０は凹部構成部材３４によって形成された左右壁で囲われていて、断熱箱体３１の上方及び背方を開口するよう構成され、その開口はカバー１１２で覆われている。また、凹部５０の空間内の空気を循環させるための放熱ファン１１３を圧縮機５２と所定の間隔をとって、その側方へ横並びにして載置し、圧縮機５２に風を当てるような流れで循環し放熱を促進するよう配置されている。   Here, the compressor 52 is placed in a concave portion 50 in which the back side is recessed in a stepped shape that is one step lower on the top surface portion of the heat insulating box 31. The recess 50 is surrounded by left and right walls formed by the recess component member 34 and is configured to open above and behind the heat insulating box 31, and the opening is covered with a cover 112. Further, a flow in which a heat radiating fan 113 for circulating the air in the space of the recess 50 is placed side by side with a predetermined distance from the compressor 52 and air is applied to the compressor 52. It is arranged so as to circulate and promote heat dissipation.

次に圧縮機５２の取り付けについて以下説明をする。   Next, attachment of the compressor 52 will be described below.

圧縮機５２は凹部構成部材３４の断熱材側に載置板１１４を設置し、載置板１１４にゴム脚やバネ脚などの緩衝材１１５を介して載置され、緩衝材１１５は圧縮機５２の取り付け部１１６に嵌め込まれると共に、凹部５０上を動かない様に、載置板１１４にネジなどの取り付け部材１１７にて固定されている。   The compressor 52 is provided with a mounting plate 114 on the heat insulating material side of the recess constituting member 34, and is mounted on the mounting plate 114 via a buffer material 115 such as a rubber leg or a spring leg. And is fixed to the mounting plate 114 with an attachment member 117 such as a screw so that the concave portion 50 does not move.

以上のように構成された冷蔵庫について、以下その作用について説明する。   About the refrigerator comprised as mentioned above, the effect | action is demonstrated below.

まず、圧縮機５２を断熱箱体３１の最下方の貯蔵室である冷凍室４４の後方領域には配置せず、天面後方の凹部５０に載置することで、冷蔵室４０の使用者が手の届き難い、いわば無効スペースに近い空間を減らす代わりに、冷凍室４４の収納容積を増大し収納性を高めることができる。つまり、圧縮機５２を天面後方に位置させることは極めて冷蔵庫本体３０の内容積をうまく活用できることになる。ただし、圧縮機５２は重いため天面部での取り付け作業は困難であるが、本構成では凹部５０の断熱材側に取り付けられた載置板１１４に支持固定するものであり、圧縮機５２の取り付けはきわめて容易である。   First, the compressor 52 is not disposed in the rear region of the freezing chamber 44 that is the lowermost storage chamber of the heat insulating box 31, but is placed in the recess 50 at the rear of the top surface so that the user of the refrigerator compartment 40 Instead of reducing the space that is difficult to reach, that is, close to the invalid space, the storage capacity of the freezer compartment 44 can be increased and the storage performance can be improved. That is, positioning the compressor 52 behind the top surface makes it possible to utilize the internal volume of the refrigerator main body 30 very well. However, since the compressor 52 is heavy, it is difficult to mount the compressor 52 on the top surface portion. However, in this configuration, the compressor 52 is supported and fixed to the mounting plate 114 attached to the heat insulating material side of the concave portion 50. Is very easy.
