Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an open storage case for freezing and refrigerating.Especially at night, when the front opening of the open storage case is covered with a night cover, leakage of cold air inside the refrigerator is prevented. This relates to a structure that prevents this.

[Prior art]

Traditionally, frozen and refrigerated open storage cases were the first
As shown in the figure, in order to prevent cold air from escaping, a night cover 15' is installed over the front opening 11' at night and on holidays when there are few customers, thereby maintaining a constant cooling efficiency for the products displayed inside the show case 13'. The plan was to maintain the vehicle and reduce driving ability.

[Problems with the Prior Art] The night cover 15' is a sheet-like material that tends to bend easily, and the direction of the bend changes at approximately the center of the front opening 11' of the show case so that the spirals overlap each other. Since the wrapped sheet was pulled vertically and stopped at the top and bottom of the front opening 11' by means of hooks provided at the ends of the sheet, a very large force was required to pull it up and down, making attachment and detachment time-consuming. At the same time, the end surfaces of the sheets curled up, creating gaps between the sheets and causing a large amount of heat leakage.

Moreover, as shown in FIG. 2, the side plate 16' of the recent open show case has a notch 16a' formed in the center and has a roughly shaped shape. Even if it is attached to the opening 11', there is a space 17' formed by the side plate 16' and the side end 15a' of the night cover 15', so that the inside of the show case 13' and the outside air can flow through the space 17'. Because of the communication, there was a defect that the cold air inside the refrigerator 13' leaked to the outside.

In addition, the sheet-like night cover 15' has a defect in that it has poor insulation against outside air, allowing heat from the outside to enter the inside 13' of the refrigerator, consuming a large amount of energy to cool the inside 13'. .

[Purpose of invention]

The present invention solves the problem of the prior art by shielding the space formed by the front opening of the open show case, the notch provided in the side plate, and the night cover.
The purpose is to prevent leakage of air inside the refrigerator and improve insulation.

[Means of devising]

To achieve this objective, the present invention uses cold air through a rectifier installed at the top of the front opening of the case to block the outlet opening with a cold air curtain.
A notch with a roughly shaped cross section is provided in the side plate of the case,
In a frozen/refrigerated open case where the opening is covered with a night cover at night, etc., the night cover is a plate-shaped heat insulating panel,
In the space formed by the notch of the case and the night cover, a cold air leakage prevention member is formed by forming a plate-like member having heat insulation properties into a substantially square shape, so that the bent part comes into contact with the surface of the night cover. , which is removably installed.

〔Example〕

The present invention will be explained below with reference to drawings showing embodiments.

Reference numeral 1 designates a first air path in which a cooler 2 and a blowing means 3 are arranged to cool the air sucked in from the inner suction port 4 at the lower part and blow it out from the inner air outlet 5 at the upper part;
Further, a blower means 7 is arranged in the second air passage 6 so that the air taken in from the lower outer air intake port 8 is blown out from the upper outer air outlet 9 as it is, and the inner air outlet 5 and the outer air outlet 9 are A common rectifying device 10 is installed so as to straddle the two, thereby forming two good air curtains in the large opening 11 at the front. Reference numeral 12 denotes a shelf for displaying articles in the warehouse 13, and a lighting lamp 14 for illuminating the displayed articles is attached to the lower end of the shelf. Reference numeral 15 indicates the opening 11 at night or when there are few customers.
A night cover that is attached to the night cover 15.
is a heat insulating panel made by gluing and fixing a thin plate-like surface material made of aluminum, synthetic resin, etc. to both sides of a plate-like heat insulating material, and then gluing and fixing a synthetic resin frame around it.・It has a configuration in which a mounting bracket 15b is attached to the lower part. In addition, a space 17 formed by the side end 15a of the night cover 15 and the notch 16a having a roughly shaped cross section formed in the side plate 16 is made of a synthetic resin such as vinyl chloride, and a plate-like material having heat insulating properties is formed. A cold air leak prevention member 18 formed into a substantially shaped member is disposed to shield the space 17, and the cold air leak prevention member 18 is attached to the end of the display shelf 12 and the inner surface of the side plate 16, as shown in FIG. The bent portion 18a of the cold air leak prevention member 18 is brought into contact with the surface of the night cover 15 to define the mounting position of the cold air leak prevention member 18. Furthermore, in order to facilitate the attachment of the cold air leak prevention member 18, an attachment guide member may be provided on the inner surface of the side plate 16.

The present invention constructed as described above first attaches the night cover 15 to the front opening of the open show case, and then inserts the cold air leak prevention member 18 into the gap 19 formed by the side plate 16 and the display shelf 12. While shielding the space 17, the bending portion 18a of the cold air leak prevention member 18 defines the mounting position,
In addition, since the adhesion between the surface of the night cover 15 and the bent portion 18a of the cold air leak prevention member 18 is improved, leakage of cold air from the measuring portion of the open show case can be prevented.

[Effect of idea]

As described above, the present invention allows cool air to pass through the rectifier 10 provided above the front opening 11 of the case, and closes the blowout opening 11 with a cold air curtain, and at the same time, the side plate 16 of the case has a notch 16a having a roughly shaped cross section.
The opening 11 is covered with a night cover 15 at night.
In the freezing/refrigerating open show case which is covered with A freezing/refrigerating open storage case characterized in that a cold air leak prevention member 18, which is a plate-like member formed into a substantially shape, is removably disposed such that a bent portion 18a abuts the surface of the night cover 15. Therefore, it is possible to prevent the air inside the refrigerator from leaking to the outside, and it is possible to prevent the air inside the refrigerator from leaking to the outside by installing a night cover with heat insulation properties and a cold air leakage prevention member in the front and side openings of the open shower case. Since the heat insulation property can be improved, it has the effect of reducing the energy consumption required to cool the inside of the refrigerator, and has a great practical effect in terms of energy saving.

In addition, the cold air leakage prevention member 18 installed between the notch 16a of the side plate 16 with a roughly shaped cross section and the night cover 15 is removable, so if you remove the cold air leakage prevention member 18 during the day, the cold air leakage prevention member 18 can be removed from the notch 16a. Since the inside of the show case can be seen, the display effect is enhanced, and it is also possible to take out the product by extending the hand through the notch 16a.
