Description

[Detailed Description of the Invention] The present invention relates to a refrigerated freezer case in which the front side of the opening for entering and exiting products is covered with a glass door.

A conventional example of this type of freezer/refrigerator case will be first explained with reference to FIG. 1, thereby clarifying the purpose of the present invention. FIG. 1 is a longitudinal sectional side view showing a conventional example, in which a partition plate 16 is provided in the freezer/refrigerator case body 10, and a product storage 13 and a cold air circulation path 14 are provided.
In this cold air circulation path 14, a cooler 3 is formed.
and a blower 4 are installed.

In addition, a cold air suction port 8 is provided at one end of the cold air circulation path 14.
A cold air outlet 7 is provided at the other end, and each of them faces the lower and upper ends of the product entry/exit opening 11 formed on the front of the case body 10, and the cool air is supplied to the partition plate 16 on the back of the product storage 13. Blowout hole 17
will be established.

Furthermore, the front surface of the opening 11 is covered with a glass door 12 in which a glass plate 1 is fitted into the framework 2 via an airtight gasket 5.

The air A sucked in from the suction port 8 in this way is cooled by the cooler 3, and then forcedly blown through the cold air circulation path 14 by the blower 4 and blown out from the air outlet 7 and the back of the storage 13. The cold air blown out to the front of the refrigerator 13 spreads in various directions, causing many inconveniences as described below.

That is, due to the diffusion of the cold air, the circulation of cold air is not performed smoothly, and the glass plate 1, the frame 2, the airtight gasket 5, and the case body 10 are all cooled down to their outer surfaces by contact with the diffused cold air. Because of this, the cooling load increases, and
There was a drawback that dew condensation formed on the outer surface of the glass plate 1 and the like.

In particular, in order to prevent condensation, it is necessary to attach a heater or make the glass plate 1 etc. have a multi-layer structure so that the outer surface temperature does not fall below the condensation point, which requires cost and equipment, and if condensation occurs on the glass plate 1, there is a risk that it will become impossible to observe the inside of the product storage room 13.

The purpose of this invention is to eliminate the disadvantages of the above conventional example,
To provide a freezing and refrigerating case that can smooth the flow of cold air, prevent the cold air from coming into direct contact with the glass plate of a door, and prevent dew condensation at various places.

However, according to the present invention, the purpose of the lever is to close the opening on the back side of the glass door in a freezer/refrigerator case in which the front side of the opening for entering and exiting goods is covered with a glass door via an airtight gasket. This is achieved by attaching a bulging hollow member made of transparent or translucent synthetic resin and positioning the top surface of this hollow member approximately on a line connecting the cold air outlet and the intake port of the case body. Ru.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 2 shows the first refrigerated case of the present invention.
A longitudinal side view showing an embodiment, showing the overall structure and opening 1 of the case body 10 that circulates the cold air flow A.
The structure of covering the front surface of the glass door 12 with a glass door 12 is the same as that of the conventional example, and the same components are given the same reference numerals.

The peripheral part of the hollow member 6 is attached to the frame 2 of the glass door 12.
The bulge 6' of the member 6 closes the front opening 11 of the case body 10.

Note that the top surface of the bulging portion 6' is located approximately on a line connecting the cold air outlet 7 and the suction port 8 of the case body 10, so that the cold air can be circulated more smoothly.

Further, the bulging portion 6' is made of a transparent or translucent synthetic resin material so as not to obstruct viewing of the products in the product storage 13.

Furthermore, as shown in the second embodiment of FIG. 3, if a fluorescent lamp 9 for illuminating the products in the storage area 13 is installed in the hollow part 15 of the hollow member 6, the heat of the fluorescent lamp 9 can be transferred to the storage area. The moisture is not transmitted to the inside of the refrigerator 13, and the inside of the refrigerator 13 can be kept moisture-proof and warm.

Further, in order to improve the product display effect in the storage 13, the hollow member 6 may be formed using a colored translucent material instead of the glass plate 1 which is difficult to be colored.

Next, the operation will be described. When the glass door 12 is closed, the bulge 6' of the hollow member 6 provided on the back side closes the opening 11.

Therefore, the cold air blown out from the outlet 7 and the back side of the product storage 13 hits the bulge 6' and flows downward along the bulge 6' without diffusing to the other side and reaches the inlet 8.
be sucked into. Also, the cold air hits the bulge 6',
Since there is no direct contact with the glass plate, the frame 2, or the gasket 5, the air layer within the hollow portion 15 acts as a heat insulator, and the glass plate 1 etc. are not cooled.

As described above, the freezer/refrigerator case of the present invention is a freezer/refrigerator case in which the front side of the opening for entering and exiting products is covered with a glass door via an airtight gasket, and the opening is closed on the back side of the glass door. A hollow member made of transparent or translucent synthetic resin that is bulged out is attached, and the top surface of the bulge part of this hollow member is approximately on the line connecting the cold air outlet and the inlet of the case body. Since the cool air blown out from the air outlet and the back side of the storage chamber flows along the top of the bulge of the hollow member, it is prevented from spreading in each direction at the opening.
Cool air flows smoothly from the outlet to the inlet.

At the same time, contact between the cold air and the glass plate, frame, gasket, and opening of the glass door is prevented, so the cold air is not conducted to the outside surface of the case, and condensation does not occur. This allows the product to be clearly viewed and eliminates the need for equipment to prevent condensation.

Furthermore, if a film is attached to the inner surface of the glass plate to prevent direct sunlight from entering the storage, the hollow member can prevent damage to the film and make it difficult to see the products inside the storage. It can be prevented from happening.
