Description

【０００１】
【産業上の利用分野】
本発明は冷蔵庫の排出空気の取込みをなくし効率よく凝縮器と圧縮機を冷却できる。また、容易に運搬できる冷蔵庫に関するものである。
【０００２】
【従来の技術】
従来の冷蔵庫としては実開平６−３０３２号公報にその例が示されており、図１１から図１４に従い説明する。
【０００３】
図１は冷蔵庫本体、２は機械室で、３は外箱底板、４は放熱パイプ、５は前記放熱パイプを下側に密着させた冷蔵庫の全幅のプレートである。
【０００４】
６は圧縮機、７は送風機、８は前記送風機７のファン、９は前記機械室２を左右に２分割する仕切板、１０は前記プレート５の後方に前記圧縮機６、送風機７を配設させる載置板、５ａは前記放熱パイプ４の逃げた位置にある前記プレート５に設けた空気吸込口、１１は蒸発皿、１２は機械室カバー、１２ａは機械室カバー１２に設けた空気排出口である。また、図中の矢印は空気対流の方向を示している。
【０００５】
以上のように構成された冷蔵庫について、その動作について説明する。
放熱パイプ４の逃げた位置にあるプレート５の空気吸込口５ａから送風機７で取り入れた空気は、放熱パイプ４、プレート５を通過し、送風機７、圧縮機６と対流し、機械室カバー１２に設けた空気排出口１２ａへと送風する。
【０００６】
【発明が解決しようとする課題】
しかしながら上記のような構成では、送風機７で取り入れた空気は、放熱パイプ４を下側に密着させたプレート５を通過するため吸込み空気温度が高温で、圧縮機６へ対流させるため圧縮機６を効率よく冷却することができず、冷却性能が劣るおそれがあった。
【０００７】
また、高温の対流空気が機械室カバー１２に設けた空気排出口１２ａから図１１、図１４の矢印に示すように完全に正規に排出れさず、一部前方の放熱パイプ４を有するプレート５にショートサーキットし、再度プレート５に設けた空気吸込口５ａを通過して機械室２の圧縮機６に対流する温度の高い空気を圧縮機６へ流すため、圧縮機の冷却効率の低下による性能劣化を起こす風路構成であり、また圧縮機の騒音を直接冷蔵庫前方へ伝播される構造でもあった。
【０００８】
さらに、放熱パイプ４を有するプレート５が冷蔵庫本体１の前方全幅を多い設置するため、容易に運搬用把手を自由自在に設けることができず、運搬性の悪い冷蔵庫であった。
【０００９】
本発明は、高温環境下、あるいは長期の使用、また冷蔵庫をシステムキッチン据え付け状態に使用されても、常に取り入れ空気はフレッシュエア（新鮮な温度の低い空気）で排出空気（高い温度）の取込みがないため、凝縮器、圧縮機を効果的に冷却させ、性能の劣化がなく、低騒音で、また冷蔵庫の運搬も上下、左右方向に可能なため、階段また幅の狭い所でも運搬を容易で安価にできるようにすることを目的とするものである。
【００１０】
【課題を解決するための手段】
上記の目的を達成するために本発明の冷蔵庫においては、冷蔵庫下部の全幅に設置した合成樹脂からなる底面に空気吸込口を備えたダクトカバーと、前記ダクトカバーより延出した係合片により嵌着され、ダクトカバーの底面と床面の間で冷蔵庫の奥行き方向を２分割させる全幅の遮閉板と、その後方に設けた載置板と、その載置板上に設置した機械室を左右に２分割する仕切板と、送風機と、凝縮器と、圧縮機と、空気排気口を備えた機械室カバーとからなり、前記送風機でフレッシュエアをダクトカバーを通り、凝縮器、圧縮機へ直接導き、前記機械室カバーの空気排気口から排出するものである。
【００１１】
また、ダクトカバーの一部分に一対の凹部（把手部）と載置板の一部に貫通穴を有している。
【００１２】
【作用】
本発明は上記した構成によって、ダクトカバーの下に設けた遮閉板によって排出空気の取込みがなく、冷蔵庫前方からのフレッシュエアのみをダクトカバーの全幅を利用し取り入れる風路構成のため、圧縮機、凝縮器の冷却効果が高められる。
【００１３】
さらに、冷蔵庫の運搬用把手において、ダクトカバーを利用して幅方向に一対の凹部を設け、また奥行方向は載置板の貫通穴を設けることにより、冷蔵庫の上下、左右方向の運搬性の向上が図れる。
【００１４】
【実施例】
以下、本発明の一実施例を示す冷蔵庫について図１から図１０を参照しながら説明する。
【００１５】
１３は冷蔵庫本体、１４は機械室で、１５は冷蔵庫外箱底板、１６は冷蔵庫の全幅に設けたダクトカバーを示す。１６ａはダクトカバー１６の空気吸込口、１７はダクトカバー１６の下部に取りつけられる全幅の遮閉板である。
【００１６】
１６ｂは遮閉板１７と嵌着するダクトカバー１６より延出した係合片、１８は圧縮機、１９は凝縮器、２０は送風機、２１は前記送風機２０のファン、２２は前記機械室１４を左右に２分割する仕切板、２３は前記ダクトカバー１６の後方に前記圧縮機１８、凝縮器１９、送風機２０を配設させる載置板を示す。
【００１７】
前記ダクトカバー１６の底面の一部分に一対の凹部１６ｃが形成されている。また、前記載置板２３に貫通穴２３ａを形成している。２４は機械室カバー、２４ａは機械室カバー２４に設けられた空気排出口である。
【００１８】
また、図中の矢印は空気の対流の方向を示している。
以上のように構成された冷蔵庫について動作を説明する。
【００１９】
ダクトカバー１６の空気吸込口１６ａから送風機２０で取り入れた空気は、冷蔵庫外箱底板１５とダクトカバー１６の間を通過し、送風機２０、凝縮器１９、圧縮機１８と対流し、機械室カバー２４に設けた空気排出口２４ａへと送風する。
【００２０】
また、合成樹脂でできたダクトカバー１６の前方の一部を利用して一対の凹部１６ｃと、ダクトカバー１６の後方に配設した載置板２３の一部に設けた貫通穴２３ａを形成することにより、冷蔵庫を２人で運搬する際に、まず上下方向（幅方向）は図６に示したように、１人は冷蔵庫本体１３の背面上部の把手（図示せず）を持ち、他の１人はダクトカバー１６の左右一対の凹部１６ｃの下側より手を挿入して凹部１６ｃを握持するようにして冷蔵庫本体１３を持ち上げるようにすればよい。
【００２１】
また、左右方向（奥行方向）の運搬は図７に示したように、１人は冷蔵庫本体１３の側面上部（図示せず）を持ち、他の１人は一方の手をダクトカバー１６の一対の凹部１６ｃ、他方の手を載置板２３の貫通穴２３ａに手を各々挿入して握持するようにして冷蔵庫本体１３を持ち上げればよく、冷蔵庫を上下また左右いずれの運搬ができる。
【００２２】
以上のように本実施例によれば、冷蔵庫下部に全幅にダクトカバー１６を配設し、かつダクトカバー１６の底面と床面２４の間に冷蔵庫の奥行方向を２分割させる遮閉板１７をダクトカバー１６の底面より一体に延出した係合片１６ｂに取付け、その後方に圧縮機１８、凝縮器１９、送風機２０を配設したことにより、送風機２０でダクトカバー１６の空気吸込口１６ａから取り入れた空気は、送風機２０、凝縮器１９、圧縮機１８を経て機械室カバー２４の空気排出口２４ａから完全に上方へ排出されるので、排出された空気が床面２４と載置板２３間を通って前方のダクトカバー１６の空気吸込口１６ａへ流れ、ショートサーキットすることが遮閉板１７で遮断されなくフレッシュな空気のみが吸込口１６ａから供給されるので、凝縮器１９、圧縮機１８の冷却に対して効果的である。さらに、圧縮機で発生した騒音が遮閉板で遮断されて冷蔵庫前方へ伝播される音が低減され静音である。
【００２３】
また、ダクトカバー１６、載置板２３より各々一体に把手を形成しているため、狭い階段、通路を運搬する際、冷蔵庫をその状態にあわせて上下、左右方向に運搬できるので便利でかつ安全な運搬が提供できる。
【００２４】
【発明の効果】
以上のように本発明は、冷蔵庫下部の全幅に設置した合成樹脂からなる底面に空気吸込口を備えたダクトカバーと、前記ダクトカバーより延出した係合片により嵌着され、ダクトカバーの底面と床面の間で冷蔵庫の奥行き方向を２分割させる全幅の遮閉板と、その後方に設けた載置板と、その載置板上に設置した機械室を左右に２分割する仕切板と、送風機と、凝縮器と、圧縮機と、空気排気口を備えた機械室カバーとからなり、前記送風機でフレッシュエアをダクトカバーを通り、凝縮器、圧縮機へ直接導き、前記機械室カバーの空気排気口から排出するものであり、ダクトカバーの空気吸込口から取り入れたフレッシュエアはダクトカバー内を通過し、送風機、凝縮器、圧縮機を対流した高温空気が機械室カバーの排出口から完全に上方へ送風され、遮閉板を設けているためダクトカバーの空気吸込口へショートサーキットされることがなく、常にダクトカバーの空気吸込口は新鮮な温度の低い空気を取り入れるため,凝縮器、圧縮機の冷却効果と送風機からの送風で対流効果が向上し、長期の使用、また冷蔵庫をシステムキッチン据え付け状態に使用されても、常に性能の劣化がない。

【００２５】
さらに、圧縮機の騒音が遮閉板で遮閉され、冷蔵庫前方へ耳障りな音が伝播されることがない。
【００２６】
また、全幅の合成樹脂でできたダクトカバーとその後方に圧縮機、凝縮器、送風機を配設した載置板より各々ダクトカバーに一対の把手用凹部また載置板に貫通穴を形成することにより、階段また狭い通路を運搬する場合、その状況に冷蔵庫を上下、左右方向に倒して容易に２人で安全に運搬できる利点がある。

[Industrial applications]
According to the present invention, it is possible to efficiently cool the condenser and the compressor by eliminating the intake of exhaust air from the refrigerator. The present invention also relates to a refrigerator that can be easily transported.
[0002]
[Prior art]
An example of a conventional refrigerator is shown in Japanese Utility Model Laid-Open No. 6-3032, which will be described with reference to FIGS.
[0003]
1 is a refrigerator main body, 2 is a machine room, 3 is an outer box bottom plate, 4 is a heat radiating pipe, and 5 is a full width plate of the refrigerator in which the heat radiating pipe is adhered to the lower side.
[0004]
6 is a compressor, 7 is a blower, 8 is a fan of the blower 7, 9 is a partition plate for dividing the machine room 2 into two right and left, 10 is the compressor 6 and the blower 7 disposed behind the plate 5. A mounting plate 5a is an air inlet provided on the plate 5 at a position where the heat radiating pipe 4 escapes, 11 is an evaporating dish, 12 is a machine room cover, and 12a is an air outlet provided on the machine room cover 12. It is. The arrows in the figure indicate the direction of air convection.
[0005]
The operation of the refrigerator configured as described above will be described.
The air taken in by the blower 7 from the air suction port 5a of the plate 5 at the position where the heat radiating pipe 4 has escaped passes through the heat radiating pipe 4 and the plate 5, convects with the blower 7 and the compressor 6, and flows into the machine room cover 12. The air is blown to the provided air outlet 12a.
[0006]
[Problems to be solved by the invention]
However, in the above configuration, the air taken in by the blower 7 passes through the plate 5 in which the radiating pipe 4 is adhered to the lower side, so that the suction air temperature is high. There was a possibility that cooling could not be performed efficiently and the cooling performance was inferior.
[0007]
In addition, as shown by arrows in FIGS. 11 and 14, high-temperature convection air is not completely discharged from the air discharge port 12a provided in the machine room cover 12, and a plate 5 having a radiation pipe 4 partially forward. The circuit is short-circuited, and the high-temperature air flowing through the air suction port 5a provided in the plate 5 again to the compressor 6 in the machine room 2 flows to the compressor 6, so that the performance due to the decrease in the cooling efficiency of the compressor is reduced. The structure was such that the wind path caused deterioration, and the noise of the compressor was transmitted directly to the front of the refrigerator.
[0008]
Further, since the plate 5 having the heat radiating pipes 4 is installed so as to have a large overall width in front of the refrigerator main body 1, a transport handle cannot be easily provided freely, and the refrigerator has poor transportability.
[0009]
Even if the present invention is used in a high-temperature environment or for long-term use, or when a refrigerator is installed in a system kitchen, the intake air is always fresh air (fresh low-temperature air) and the intake air (high temperature) is always taken in. There is no effective cooling of the condenser and compressor, no deterioration in performance, low noise, and the ability to transport the refrigerator vertically and horizontally, making it easy to transport on stairs and narrow places. The purpose is to make it inexpensive.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, in the refrigerator of the present invention, a fitting is provided by a duct cover provided with an air suction port on a bottom surface made of a synthetic resin and installed on the entire width of the lower portion of the refrigerator, and an engaging piece extending from the duct cover. A full width shielding plate that divides the depth direction of the refrigerator into two parts between the bottom surface of the duct cover and the floor surface, a mounting plate provided behind it, and a machine room installed on the mounting plate And a machine room cover with an air exhaust port. The blower passes fresh air through the duct cover directly to the condenser and compressor. It is guided and discharged from the air exhaust port of the machine room cover.
[0011]
The duct cover has a pair of recesses (handles) in a part thereof and a through hole in a part of the mounting plate.
[0012]
[Action]
The present invention has the above-described structure, in which the closing plate provided below the duct cover does not take in the exhaust air, and only the fresh air from the front of the refrigerator is taken in using the full width of the duct cover, so that the compressor is used. The cooling effect of the condenser is enhanced.
[0013]
Further, in the refrigerator carrying handle, a pair of recesses are provided in the width direction using a duct cover, and a through hole of the mounting plate is provided in the depth direction, so that the refrigerator can be transported in the vertical and horizontal directions. Can be achieved.
[0014]
【Example】
Hereinafter, a refrigerator according to an embodiment of the present invention will be described with reference to FIGS.
[0015]
13 is a refrigerator main body, 14 is a machine room, 15 is a refrigerator outer box bottom plate, and 16 is a duct cover provided over the entire width of the refrigerator. 16a is an air suction port of the duct cover 16, and 17 is a full width shielding plate attached to the lower part of the duct cover 16.
[0016]
16b is an engagement piece extending from the duct cover 16 fitted with the shielding plate 17, 18 is a compressor, 19 is a condenser, 20 is a blower, 21 is a fan of the blower 20, and 22 is a machine room. A partition plate 23 that is divided into two parts, left and right, denotes a mounting plate on which the compressor 18, the condenser 19, and the blower 20 are disposed behind the duct cover 16.
[0017]
A pair of recesses 16c are formed in a part of the bottom surface of the duct cover 16. Further, a through hole 23a is formed in the mounting plate 23 described above. 24 is a machine room cover, and 24a is an air discharge port provided in the machine room cover 24.
[0018]
Arrows in the figure indicate the direction of air convection.
The operation of the refrigerator configured as described above will be described.
[0019]
The air taken in by the blower 20 from the air inlet 16a of the duct cover 16 passes between the refrigerator outer case bottom plate 15 and the duct cover 16 and convects with the blower 20, the condenser 19, and the compressor 18, and the machine room cover 24 The air is blown to the air discharge port 24a provided in the air conditioner.
[0020]
In addition, a pair of recesses 16c and a through hole 23a provided in a part of the mounting plate 23 disposed behind the duct cover 16 are formed by using a part of the front of the duct cover 16 made of a synthetic resin. As a result, when the refrigerator is carried by two persons, first, as shown in FIG. 6, one person holds a handle (not shown) on the upper rear surface of the refrigerator main body 13 as shown in FIG. One person may insert his / her hand from below the pair of left and right recesses 16c of the duct cover 16 and grasp the recess 16c to lift the refrigerator body 13.
[0021]
As shown in FIG. 7, one person holds the upper side (not shown) of the refrigerator body 13 in the left-right direction (depth direction), and the other person uses one pair of the duct covers 16 with one hand. The refrigerator main body 13 can be lifted up and down or left and right by lifting the refrigerator body 13 by inserting the hands into the recesses 16c and the other hand into the through holes 23a of the mounting plate 23 and holding the hands.
[0022]
As described above, according to the present embodiment, the duct cover 16 is provided at the entire width below the refrigerator, and the shielding plate 17 for dividing the depth direction of the refrigerator into two portions between the bottom surface of the duct cover 16 and the floor surface 24 is provided. Since the compressor 18, the condenser 19, and the blower 20 are disposed behind the engaging piece 16 b integrally extending from the bottom surface of the duct cover 16, the blower 20 allows the air to be removed from the air suction port 16 a of the duct cover 16. The taken-in air passes through the blower 20, the condenser 19, and the compressor 18, and is completely discharged upward from the air discharge port 24a of the machine room cover 24, so that the discharged air flows between the floor surface 24 and the mounting plate 23. Flows through the air inlet 16a of the duct cover 16 in front of it, and short circuit is not blocked by the closing plate 17 and only fresh air is supplied from the inlet 16a. 9, it is effective for cooling the compressor 18. Furthermore, the noise generated by the compressor is blocked by the shielding plate, and the sound transmitted to the front of the refrigerator is reduced, so that the noise is reduced.
[0023]
Also, since the handle is integrally formed from the duct cover 16 and the mounting plate 23, the refrigerator can be transported vertically and horizontally according to the condition when transporting narrow stairs and passages, so that it is convenient and safe. Transportation can be provided.
[0024]
【The invention's effect】
As described above, the present invention provides a duct cover provided with an air suction port on a bottom surface made of a synthetic resin installed over the entire width of a lower portion of a refrigerator, and an engagement piece extending from the duct cover. A full-width shielding plate that divides the depth direction of the refrigerator into two parts between the floor and the floor, a mounting plate provided behind it, and a partition plate that divides the machine room installed on the mounting plate into two right and left parts. A blower, a condenser, a compressor, and a machine room cover having an air exhaust port.The blower directs fresh air through a duct cover, directly to a condenser and a compressor. The fresh air is exhausted from the air exhaust port, and the fresh air taken in from the air inlet of the duct cover passes through the duct cover, and the high-temperature air convected through the blower, condenser, and compressor is completely discharged from the exhaust port of the machine room cover. Upward Since the air is blown and the shielding plate is provided, there is no short circuit to the air inlet of the duct cover, and the air inlet of the duct cover always takes in fresh low-temperature air. The convection effect is improved by the cooling effect and the air blowing from the blower, and the performance is not always deteriorated even when used for a long time or when the refrigerator is installed in the system kitchen.

[0025]
Furthermore, the noise of the compressor is shielded by the shielding plate, so that harsh sounds are not transmitted to the front of the refrigerator.
[0026]
In addition, a pair of recesses for handles and through holes in the mounting plate are formed on the duct cover from the mounting plate on which the duct cover made of synthetic resin of full width and the compressor, condenser, and blower are arranged behind it. Therefore, when transporting stairs or narrow passages, there is an advantage that the refrigerator can be easily transported safely by tilting the refrigerator up, down, left and right in that situation.
