【発明の詳細な説明】
本発明はシヨーケースの使用時に生じる床面で
の冷気滞溜を防止した空気調和装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner that prevents cold air from accumulating on the floor surface when a show case is used.
オーブン型冷蔵シヨーケースは庫内に収納した
冷却器で冷却された冷気をもつて商品展示室を冷
却すると同時に、商品展示室の前面開口は同様に
して冷却された冷気によるエアーカーテンで遮蔽
された構造を有している。 The oven-type refrigerated display case cools the product display room with cold air cooled by a cooler stored inside the cabinet, and at the same time, the front opening of the product display room is shielded by an air curtain made of similarly cooled air. have.
エアーカーテンは商品展示室への外気の侵入お
よび該展示室からの冷気の流出を防止しているの
であるが、僅かずつ冷気が溢流することは避け難
く、このために、多数のオーブン型冷蔵シヨーケ
ースを設置して使用するときには床面に一定の冷
気滞溜層が形成される欠点を有していた。 Air curtains prevent outside air from entering the product display room and preventing cold air from flowing out from the product display room, but it is difficult to avoid a slight overflow of cold air, which is why many oven-type refrigerators When a show case is installed and used, there is a drawback that a certain layer of cold air is formed on the floor surface.
本発明は斯る点に鑑み、シヨーケースの設置さ
れた床面付近における冷気滞溜の防止をし設置場
所の空気調和を主な目的としたものであり、以下
に図面に従い説明する。 In view of the above, the present invention aims to prevent cold air from accumulating in the vicinity of the floor surface where the show case is installed, and to achieve air conditioning at the place where the show case is installed, and will be described below with reference to the drawings.

ている。 Reference numeral 1 denotes the main body of an oven-type refrigerated show case, and a product exhibition room 3 having shelves 2 for placing products has a product take-out opening 5 shielded by an air curtain 4 on the front side. The cooler 6 is an air curtain that cools the product display room 3 to a temperature suitable for storing products by letting the cold air cooled by the cooler flow out from the air outlet 7, and at the same time blocks the front opening 5 of the product display room. It is installed in the cold air circulation path 8 that forms the.

続筒であり、例えば二台のシヨーケースを並置し
た場合は第１図に示す形状となる。 Reference numeral 9 denotes an air intake duct formed independently of the cold air circulation path 8 below the product exhibition room 3, and the duct is connected to the cold air accumulation layer 10 on the floor outside the warehouse through the front plate 11. It has small holes 12 that communicate with each other. Reference numeral 13 denotes a connection tube for the intake duct 9 used when a plurality of oven-type show cases are used side by side.For example, when two show cases are placed side by side, the shape is as shown in FIG. 1.
又、１４は吸気ダクト９を介して吸入された庫

層１０の冷気を大量に吸い込むときは、商品展示
室３の圧力に比較して庫外側の圧力が低くなり、
このために、商品展示室３の冷気が庫外に溢流し
易くなる。しかし、吸気ダクト９から吸入されて
きた空気をすみやかにシヨーケースの設置場所へ
戻ための送風機１５を吸気ダクト９のみに設置す

ないためにも加温装置或いは冷房装帯等の適当な
空気調和付属品を使用している。 Reference numeral 14 denotes a recirculation device that returns the cool air taken in from outside the refrigerator to the installation location of the show case through the intake duct 9, and is connected to or connected to the duct 9 that is continuous with one end of the intake duct 9 and protrudes from the main body 1. They are connected via a hollow duct 9', and incorporate a filter, heating device, deodorizing device, blower device, etc. as necessary. That is, when a large amount of cold air from the cold air retention layer 10 is sucked in from the intake duct 9, the pressure outside the refrigerator is lower than the pressure in the product display room 3.
For this reason, the cold air in the product display room 3 tends to overflow to the outside of the warehouse. However, if the blower 15 for quickly returning the air sucked in from the intake duct 9 to the installation location of the air case is installed only in the intake duct 9, the pressure difference between the intake duct 9 and the outlet 16 will increase, so the recirculation device It is preferable to house an air blower in the air conditioner 14, and also use appropriate air-conditioning accessories such as a heating device or a cooling belt in order to avoid discomfort to the purchaser.

ともない。 In this way, the device of the present invention sucks the overflowing cold air from the exhibition room onto the floor outside the warehouse independently from the cold air circulation path of the oven-type show case, so there is no effect on the cold air circulation path or cooling capacity. It is possible to prevent the formation of a cold air accumulation layer outside the refrigerator without any adverse effects. In other words, if the amount of cold air intake is adjusted to a level that creates a slight airflow that is not felt by the human body, product buyers will experience both the coldness of their feet due to the cold air and the feeling of coldness of their feet caused by the airflow. It has the effect of preventing the formation of cold air accumulation inside the case without causing any change in the cold air flow in the cold air circulation path due to the influence of outside air flow or pressure.
In addition, since the inhaled accumulated cold air is returned to the place where the show case is installed via the circulation device, it is possible to harmonize the air above the show case, that is, near the ceiling of the store, and to reduce the difference in pressure between the outside and outside of the product display room. There is no increase in the amount of cold air overflowing from the exhibition room. Moreover, the overflow cold air that is returned to the place where the show case is installed is used in a recirculation device to perform air conditioning such as heating or cooling using an appropriate air conditioning accessory, and then returned, which causes discomfort to the product purchaser. Not at all.
