Abstract

PURPOSE:To prevent the adhesion of frost to the inner wall surface of a transparent box body and permit commodities in a displaying refrigerating chamber to be seen well from the outside of a showcase by a method wherein a guide member, on which a plurality of holes for inserting the commodities loosely are formed, is provided in the displaying refrigerating chamber while a space, formed below the refrigerating chamber, is utilized as a cold air passage communicating with a cooling chamber. CONSTITUTION:Vessels of respective commodities are inserted into respective holes 18 on a guide member 15 and, thereafter, machines in a machine room 2 and a cooling chamber 3 are operated. Cold air flows from a cold air outlet port 11 into a cold air passage 14, formed of the guide member 15 provided in a displaying refrigerating chamber 10 and the upper wall surface of the cooling chamber 3, then, cools soft drinks inserted into the holes 18 of the guide member 15 and, thereafter, returns into the cooling chamber 3 again through a suction port 12. Accordingly, the cold air will never flow directly into a space formed of the transparent box body 9 and the guide member 15 whereby a temperature difference between the inside and the outside of the displaying refrigerating chamber 10 becomes small and frosting on the inner wall surface of the transparent box body 9 is eliminated.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a product display refrigerated box, that is, a showcase, and in particular, to a product display refrigerated box, that is, a showcase, and more particularly, to Related to showcases (prior art) In general, showcases for displaying and refrigerating products such as chilled soft drinks, juices, and so-called health drinks in stores etc. are as shown in Figures 6 and 7. It has a box-shaped casing body 1, and a machine chamber 2 and a cooling chamber 3 are formed inside this casing body 1. The machine room 2 houses a refrigerant compressor 4, a condenser 5, a condenser fan 6, etc., and the cooling room 3 houses an evaporator 7, an internal fan 8, etc.

A transparent box body 9 made of, for example, a transparent plate of plastic or the like is placed on the upper part of the casing body 1 so that its opening edge side is in contact with the upper surface of the upper wall surface of the cooling chamber 3. 9 forms an exhibition cold room 10. A cold air outlet 11 and an intake port 12 are formed on the earthen wall surface of the cooling chamber 3 to communicate the cooling chamber 3 and the exhibition cold room 10 with each other. And this exhibition cold room 10
By displaying product 13 in
3 can be easily seen, and products 13 can be taken in and out by lifting the transparent box body 9 by hand.

Thus, the refrigerant pressurized by the refrigerant compressor 4 is condensed and liquefied by exchanging heat with the outside air drawn in by the condenser fan 6 in the condenser 5, and this liquefied refrigerant is provided in the cooling chamber 3. It is sent to evaporator 7. Therefore, the air in the cooling chamber 3 is cooled by the evaporator 7, and the cool air is supplied by the internal fan 8 from the cold air outlet 11 to the exhibition cold room 10 as shown by the arrow in FIG. Product 13 is kept cold. The cold air that has been kept cold flows back into the cooling chamber 3 from the intake port 12.

(Problem to be solved by the invention) However, in the above-mentioned showcase, the cooling chamber 3
The products 13 are kept cold by the cold air flowing into the exhibition cold room 10 from the outside, but in this case, the cold air directly hits the inner wall surface of the transparent box 9 forming the exhibition cold room 10, so that the inside of the exhibition cold room 10 is kept cool. Due to the temperature difference between the outside and the outside, dew adheres to the inner wall surface of the transparent box 9, causing problems such as the products 13 inside the exhibition cold room 10 becoming invisible. In order to prevent this, if an evaporation device is provided to evaporate the water that accumulates on the bottom of the exhibition cold storage room 10, there will be problems such as a significant increase in cost. In view of these points, the present invention eliminates the above-mentioned problems, prevents dew from adhering to the inner wall surface of the transparent box forming the exhibition cold storage room, and prevents the products in the exhibition cold storage room. The purpose is to provide a showcase that allows for good visibility.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a showcase in which a machine room and a cooling room are provided inside a casing body, and an exhibition refrigerating room formed by a transparent box body. A guide member having a plurality of holes into which products are loosely inserted is provided in the display refrigerating chamber, and a space formed below the guide member is a cold air passage communicating with the cooling chamber. It is.

(Function) According to the present invention, the hollow space formed below the guide member, which is provided inside the transparent box forming the exhibition refrigerated room and into which a large number of products can be loosely inserted, is used for cooling the products. cold air circulates. Therefore, this cold air does not directly hit the inner wall surface of the transparent box (and prevents dew from adhering to the inner wall surface of the transparent box and making it difficult to see the product).

(Example) Hereinafter, a case where an example of the showcase of the present invention is applied to a bottled soft drink will be described with reference to FIGS. 1 to 5. Note that the same components as those in the specific example of the prior art described above will be described with the same reference numerals.

The casing body 1 is box-shaped and has a machine room 2 inside which houses a refrigerant compressor 4, a condenser 5, a condenser fan 6, etc.
and a cooling chamber 3 in which an evaporator 7, an internal fan 8, etc. are housed, and the upper part of the casing body 1 has a
For example, a transparent box 9 made of a transparent plate made of plastic or the like is placed so that its open end is in contact with the upper surface of the upper wall of the cooling chamber 3, and the transparent box 9 allows the exhibition cold room 10 to be
is formed. By the way, a guide member 15 for forming a cold air passage 14 is installed in the exhibition refrigerating room 10 formed by the transparent box 9.

The guide member 15 is made of plastic or the like, has a box shape with a bottom and has a cross-sectional area slightly smaller than the cross-sectional area of the transparent box 9, and has a height corresponding to approximately 1/2 of the height of the transparent box 9. flange portion 1 formed on the outer periphery of the opening end thereof.
6 is mounted and fixed on the upper wall surface of the cooling chamber 3. and,
A cold air outlet 11 and an intake port 12 are formed on the upper wall surface of the cooling chamber 3 to communicate the cooling chamber 3 with a cold air passage 14 formed between the guide member 15 and the earth wall surface of the cooling chamber 3. There is. Further, the top plate 17 of the guide member 15
A number of holes 18 having a diameter slightly larger than the outer diameter of the soft drink container are formed in the container.

Since the present invention is configured in this way, the guide member 15
When the machines in the machine room 2 and the cooling room 3 are operated after inserting a soft drink container into each of the equations 18, cold air flows from the cold air outlet 11 to the guide member 15 provided in the exhibition refrigerator room 10 and the cooling room. The cold air flows into the cold passage 14 formed by the upper wall surface of the guide member 15, keeps the soft drink inserted in the hole 18 of the guide member 15 cold, and then flows back into the cooling chamber 3 through the intake port 12. Therefore, cold air does not flow directly into the space formed by the transparent box 9 and the guide member 15, and the temperature difference between the inside and outside of the exhibition cold storage room 10 is reduced, and the inner wall surface of the transparent box 9 dew will no longer adhere to the surface.

Note that FIGS. 4 and 5 are views showing other embodiments of the showcase of the present invention, in which the upper wall surface of the cooling chamber 3 of the casing body 1 is formed with an upward slope from the front toward the rear. At the same time, the top wall of the transparent box body 9 is also inclined obliquely upward parallel to this, so that the products 13 can be easily seen and taken in and out. And the cold air passage] 4
An evaporator 7 is disposed at the top position. Therefore, the cold air generated in the evaporator 7 flows by natural convection as shown by the arrows in FIG. 5 to keep the product 13 cool, and there is no need to provide the internal fan 8 as in the first embodiment.

Note that since the transparent box 9 is placed on the top surface of the casing body 1, the transparent box 9 must be lifted by hand to put in and take out containers, but one end edge of the transparent box 9 and the casing body 1 are connected to each other by a hinge or the like. The transparent box body 9 may be opened and closed so that containers can be taken in and taken out, but the invention is not limited to this. Alternatively, the transparent box 9 may be fixed to the casing body 1, and an opening/closing window or the like may be formed on the side wall of the transparent box 9.

〔Effect of the invention〕

As explained above, the present invention provides a guide member in which a plurality of holes into which products are loosely inserted is provided inside a display refrigerating room formed of a transparent box, and a guide member is formed with a plurality of holes into which products are loosely inserted. Since the cold air is made to flow through the cold air passage formed by the cooling chamber and the hollow space below the guide member, the cold air does not directly hit the inner wall surface of the transparent box, and therefore the inside and outside of the exhibition cold room are connected. The temperature difference between the two is reduced, and dew does not adhere to the walls of the exhibition/refrigerated room, and the products are not obscured by dew.

Furthermore, since the area through which the cold air flows is narrower than when the cold air flows throughout the entire exhibition refrigerated room, the cooling time is shortened and the cooling capacity is increased. Further, the upper surface of the casing body does not become wet due to falling dew, and there is no need to provide an evaporator for evaporating water due to dew, so the showcase can be made at a lower cost.
