Description

本発明は、ショーケース，自動販売機，冷蔵庫など冷却装置を備えた機器における冷気の流通構造に関する。   The present invention relates to a cold air distribution structure in a device equipped with a cooling device such as a showcase, a vending machine, and a refrigerator.

この種の冷却機器の一例としては、特許文献１に記載された冷蔵庫が知られている。この冷蔵庫は庫内上部に設けたハウジング内に蒸発器及び蒸発器ファンが配置されている。ハウジング内は仕切り板によって空間が仕切られており、該仕切り板に蒸発器ファンが付設されている。蒸発器は蒸発器ファンの風下側であってハウジング内の天井面に付設されている。また、蒸発器は、その下面とハウジング底面との間に所定の空隙が形成されるように配置されている。蒸発器下面とハウジング底面との間隙にはドレンパンが設けられている。蒸発器から滴下するドレン水は該ドレンパンに受容される。
特開２００４−３３３０９３号公報 As an example of this type of cooling device, a refrigerator described in Patent Document 1 is known. In this refrigerator, an evaporator and an evaporator fan are arranged in a housing provided in the upper part of the refrigerator. The interior of the housing is partitioned by a partition plate, and an evaporator fan is attached to the partition plate. The evaporator is attached to the ceiling surface in the housing on the leeward side of the evaporator fan. Moreover, the evaporator is arrange | positioned so that a predetermined | prescribed space | gap may be formed between the lower surface and the housing bottom face.

JP 2004-333093 A

しかし、特許文献１に記載の冷蔵庫では、蒸発器ファンにより蒸発器方向に送風された空気は、蒸発器内に流入するだけでなく、蒸発器下面とハウジング底面の間の空隙を通過してしまう。また、蒸発器内に流入した後に蒸発器から前記空隙に漏れ出る空気もある。このため、冷却効率の向上には限界があった。   However, in the refrigerator described in Patent Document 1, the air blown in the direction of the evaporator by the evaporator fan not only flows into the evaporator but also passes through the gap between the lower surface of the evaporator and the bottom surface of the housing. . There is also air that leaks from the evaporator into the gap after flowing into the evaporator. For this reason, there was a limit in improving the cooling efficiency.

このような問題を解決するために蒸発器・ハウジング底面間の空隙をなくすことも考えられる。より具体的には、前述のように該空隙にはドレンパンが介在しているため、蒸発器とドレンパン，ドレンパンとハウジング底面とを密着させることが考えられる。しかし、蒸発器とドレンパンを密着させると、蒸発器表面に付着したドレン水がドレンパン上に滴下しずらく、ドレン水の排水を確実に行うことが困難であるという問題があった。   In order to solve such a problem, it is conceivable to eliminate the gap between the evaporator and the bottom surface of the housing. More specifically, since the drain pan is interposed in the gap as described above, it can be considered that the evaporator and the drain pan, and the drain pan and the housing bottom face are brought into close contact with each other. However, when the evaporator and the drain pan are brought into close contact with each other, the drain water adhering to the surface of the evaporator is difficult to drip onto the drain pan, and there is a problem that it is difficult to reliably drain the drain water.

A ventilation path is formed so as to discharge from the upper part of the leeward side of the evaporator, and a drainage hole for discharging drain water dripped from the evaporator is formed on the bottom surface of the ventilation path below the evaporator. Further, in the present application, a ventilation path for circulating cold air in the horizontal direction, a blower disposed in the ventilation path, an evaporator disposed on the wind of the blower and constituting a part of the cooling cycle and closed on both sides , In the cooling air circulation structure in the cooling device, the rear surface of the evaporator is provided with a closing plate for restricting the air flowing into the evaporator from being discharged from the rear surface and leading to the lower part of the evaporator, and the lower surface of the evaporator A gap is formed between the airflow path and the bottom of the ventilation path, and a ventilation path is formed so that all the air circulated by the blower flows in from the upper part of the windward side of the evaporator and is discharged from the lower part of the evaporator.

Moreover, since the ventilation path is formed so that all the air which distribute | circulates with an air blower may be guide | induced in an evaporator, high cooling efficiency is obtained.

本発明の一実施の形態について図面を参照して説明する。本実施の形態では、ショーケースにおける冷気流通構造について説明する。図１はショーケースの外観斜視図、図２は機械室の断面図である。   An embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a cold air circulation structure in a showcase will be described. FIG. 1 is an external perspective view of a showcase, and FIG. 2 is a cross-sectional view of a machine room.

ショーケースは、図１に示すように、前面が開口した箱状のショーケース本体１と、ショーケース本体１の前面開口を開閉する前面扉２とを備えている。ショーケース本体１の上部空間は商品収納室３となっている。商品収納室３の下側には機械室４が形成されている。商品収納室３と機械室４とは仕切板５により仕切られている。   As shown in FIG. 1, the showcase includes a box-shaped showcase body 1 having an open front surface, and a front door 2 that opens and closes the front opening of the showcase body 1. The upper space of the showcase body 1 is a product storage room 3. A machine room 4 is formed below the product storage room 3. The product storage room 3 and the machine room 4 are partitioned by a partition plate 5.

図２に示すように、機械室４には、冷却域と非冷却域とを仕切る断熱壁１１が形成されている。断熱壁１１は、前部及び後部においては仕切板５の下面と密着し、中央部は前部が斜めに傾斜し且つ後部が直立した凹部形状となっている。この断熱壁１１と仕切板５との間の空間は、冷気を循環させる通風路１２となっている。具体的には、仕切板５の前部には吸入口５ａが形成されており、仕切板５の後部には吐出口５ｂが形成されている。すなわち、商品収納室３と通風路１２は連通している。   As shown in FIG. 2, the machine room 4 is formed with a heat insulating wall 11 that partitions the cooling area and the non-cooling area. The heat insulating wall 11 is in close contact with the lower surface of the partition plate 5 at the front part and the rear part, and the central part has a concave shape in which the front part is inclined obliquely and the rear part is upright. A space between the heat insulating wall 11 and the partition plate 5 is a ventilation path 12 for circulating cold air. Specifically, a suction port 5 a is formed in the front portion of the partition plate 5, and a discharge port 5 b is formed in the rear portion of the partition plate 5. That is, the product storage chamber 3 and the ventilation path 12 communicate with each other.

通風路１２内には、冷却サイクルの一部を構成する蒸発器２１と、蒸発器２１方向に空気を送風する送風機２２とが配置されている。送風機２２は、通風路１２内において上下に亘って形成された取付フレーム２３に付設されており、吸入口５ａから吸入された庫内空気を後方に向けて送風する。蒸発器２１は、両側面を除く４面において空気の取り入れ・排出が可能なフィンタイプのものであり、上面は仕切板５の下面により閉鎖されている。また、蒸発器２１の前面は閉鎖板２４が付設されており、蒸発器２１前面からの蒸発器２１内への空気の流入を制限している。蒸発器２１の下面と通風路１２の底面との間には所定の間隔が形成されている。また、蒸発器の後面下部は通風路１２の直立部により閉鎖され、後面上部は通風路１２と連通している。このような構造により、吸入口５ａから吸入された空気は送風機２２により後方に送られ、閉鎖板２４により蒸発器２１と通風路１２との空隙に導かれる。そして、該空気は、蒸発器２１の下面から蒸発器２１内に流入して冷却される。冷気は、蒸発器２１の後面上部から通風路１２に吹き出し、吐出口５ｂを介して商品収納室３に吐出する。   In the ventilation path 12, the evaporator 21 which comprises a part of cooling cycle, and the air blower 22 which blows air in the direction of the evaporator 21 are arrange | positioned. The blower 22 is attached to an attachment frame 23 formed vertically in the ventilation path 12 and blows the air in the warehouse sucked from the suction port 5a backward. The evaporator 21 is of a fin type capable of taking in and discharging air on four surfaces excluding both side surfaces, and the upper surface is closed by the lower surface of the partition plate 5. Further, the front face of the evaporator 21 is provided with a closing plate 24 to restrict the inflow of air from the front face of the evaporator 21 into the evaporator 21. A predetermined interval is formed between the lower surface of the evaporator 21 and the bottom surface of the ventilation path 12. The lower part of the rear surface of the evaporator is closed by the upright part of the ventilation path 12, and the upper part of the rear surface communicates with the ventilation path 12. With such a structure, the air sucked from the suction port 5 a is sent backward by the blower 22, and is guided to the gap between the evaporator 21 and the ventilation path 12 by the closing plate 24. The air flows into the evaporator 21 from the lower surface of the evaporator 21 and is cooled. The cold air is blown out from the upper rear surface of the evaporator 21 to the ventilation path 12 and discharged into the product storage chamber 3 through the discharge port 5b.

断熱壁１１の下方には、基台３１上に、冷却サイクルを構成する凝縮器４１、内部熱交換機（インタクーラ）４２、圧縮機４３、主として凝縮器４１用の送風機４４が設置されている。断熱壁１１には、蒸発器２１の下方にドレン水を排出するための排水孔１１ａが形成されている。排水孔１１ａには排水用ホース４５が接続されており、ドレン水は基台３１の下方に配置したドレンパン４６に導かれる。   Below the heat insulating wall 11, a condenser 41, an internal heat exchanger (intercooler) 42, a compressor 43, and a blower 44 mainly for the condenser 41 are installed on the base 31. The heat insulating wall 11 is formed with a drain hole 11 a for discharging drain water below the evaporator 21. A drainage hose 45 is connected to the drainage hole 11 a, and drain water is guided to a drain pan 46 disposed below the base 31.

上記断熱壁１１、断熱壁１１の上側に配置されている蒸発器２１等の各機器、下側に配置されている凝縮器４１等の各機器は、基台３１上に一体に設置されている（ユニット化）。また、基台３１は各機器が搭載された状態で前方に引き出し可能となっている。これによりメンテナンス性が向上する。   The heat insulation wall 11, the devices such as the evaporator 21 disposed above the heat insulation wall 11, and the devices such as the condenser 41 disposed below are integrally installed on the base 31. (Unitization). In addition, the base 31 can be pulled forward with each device mounted. This improves the maintainability.

図３に本実施の形態に係るショーケースの冷却サイクルを示す。この冷却サイクルはＣＯ2を冷媒としたものであり、図３に示すように、圧縮機４３，凝縮器４１，内部熱交換機４２，膨張弁５１，蒸発器２１，内部熱交換機４２を直列に接続したサイクルを形成している。 FIG. 3 shows a cooling cycle of the showcase according to the present embodiment. This cooling cycle uses CO 2 as a refrigerant, and as shown in FIG. 3, a compressor 43, a condenser 41, an internal heat exchanger 42, an expansion valve 51, an evaporator 21, and an internal heat exchanger 42 are connected in series. Forming a cycle.

このようなショーケースによれば、図２に示したように、送風機２２により送風された全ての空気が蒸発器２１の下面から該蒸発器２１内に流入するので、冷却効率が向上する。また、蒸発器２１下面と通風路１２底面との間には所定の間隙が形成されているので、蒸発器２１に付着したドレン水を確実に滴下させることができる。なお、該ドレン水は排水孔１１ａ及び排水用ホース４５によりドレンパン４６に導かれる。また、機械室４内の各機器は基台３１上にユニット化されているので、メンテナンス性が向上する。   According to such a showcase, as shown in FIG. 2, since all the air blown by the blower 22 flows into the evaporator 21 from the lower surface of the evaporator 21, the cooling efficiency is improved. Further, since a predetermined gap is formed between the lower surface of the evaporator 21 and the bottom surface of the ventilation path 12, the drain water adhering to the evaporator 21 can be surely dropped. The drain water is guided to the drain pan 46 by the drain hole 11a and the drain hose 45. Moreover, since each apparatus in the machine room 4 is unitized on the base 31, maintenance property improves.
