Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a showcase in which a storage compartment is divided into a plurality of compartments.

[0002]

2. Description of the Related Art Conventionally, a showcase of this type is divided into upper and lower compartments by a partition member, as disclosed in, for example, Japanese Patent Laid-Open No. 2-161276 (F25D17 / 08).
The lower part serves as a refrigerating region, and the upper part serves as a refrigerating region by introducing cold air, or as a warming region by heating from a heating element. With such a configuration, the storage volume in the showcase can be effectively utilized even if the composition ratio of the refrigerated product and the hot-stored product changes depending on the season.

In the showcase as disclosed in the above publication, the front opening of the space above and below the partition member is closed together by a single door for the purpose of eliminating the complexity of opening and closing the door and reducing the cost. Since this door is also composed of a transparent glass door, a gasket for sealing the door and the opening edge of the storage chamber is usually attached to the opening edge side. FIG. 5 shows the shape of the gasket 100 corresponding to the upper door of the above publication. The gasket 100 is made of a soft synthetic resin, and has a rectangular shape that matches the peripheral shape of the door and has an outer peripheral portion 101 attached to the opening so as to surround the entire opening above and below the partition member. The partition 102 is attached to the front surface of the partition member. When the door is closed, the outer peripheral portion 101 of the gasket 100 comes into close contact with the inside of the door, and the partition portion 102 comes into close contact with the gasket contact member provided on the door.

[0004]

However, since the outer peripheral portion 101 and the partition portion 102 are separate bodies, the gaps 103 and 103 are inevitably formed between them. When such a gap 103 is formed, the space above and below the partition member is the gap 10.
3 will be communicated, and independent temperature control of each room will not be possible. In particular, when the upper side and the lower side are separately used for hot storage and cold storage, air convection occurs between the upper and lower chambers, which adversely affect each other. Therefore, in the above-mentioned publication, the upper and lower sides of the gasket abutting member provided on the door are projected rearward from the door, and adiabatic air layers are formed above and below the partition 102 with the partition 102 in contact. However, with such a shape, when the door is opened, the abutting member may project toward the front side and may come into contact with the user, and also the heat insulating performance between the upper and lower chambers on the left and right of the partition 102 may deteriorate. There was a problem.

The present invention has been made in order to solve the above-mentioned conventional technical problems, and provides a showcase in which the heat insulating performance is improved in the opening portion between a plurality of compartments formed in the storage compartment. The purpose is to provide.

It is spaced from the plate 22. Further, transparent acrylic resin wind direction plates 53 and 54 extending upward are also attached to the cold air suction ports 46 and 47.

The heat insulating partition plates 23 and 24 are provided with a space between the central heat insulating partition plate 22 and the side plate 4, respectively.
This distance is such that the dampers 56, 56 and 5 are slidable left and right.
It can be opened and closed by 7, 57. Further, racks 58, 58 and 59, 59 having electric heaters H are installed in the cold temperature switching chambers 26, 27. Shades 61, 62 are attached to the left and right side surfaces of the central heat insulating partition plate 22 to form a fluorescent lamp chamber 64 for housing a fluorescent lamp 63. The fluorescent lamp chamber 64 has an opening 67 at the lower end. The wind direction plates 51 and 52 are opened upward, and the upper end communicates with the refrigerating compartment 29 at a communication portion 66 at the upper end of the shade 62 on the refrigerating compartment 29 side.

A plurality of shelves 68 are installed in the refrigerating chamber 29 on the side of the central heat insulating partition plate 22. Further, wind direction plates 51, 52 are provided.
Shelves 69 and 70 are installed in the refrigerating chambers 28 and 29 on the side. Further, in the machine room 13, the cooler 38,
A compressor 71, a condenser 72, and a condenser blower 73 that form a refrigeration cycle together with 39 are arranged.

Next, the operation of the showcase 1 will be described.
When the compressor 71 and the blowers 41 and 42 are operated with the dampers 56, 56, 57, 57 open, the cool air cooled by the cooler 38 is blown from the cool air discharge port 43 by the blower 41. 51 is blown upwards,
Some of them circulate in the refrigerating chamber 28 as they are, and some of them circulate into the cold / heat switching chambers 27 and 26 one after another from the space between the central heat insulating partition plate 22 and the heat insulating partition plates 24 and 23. Cold temperature switching chamber 26,
The cold air that has circulated in the inside 27 is the side plate 4 and the heat insulating partition plates 23,
The air flows into the refrigerating chamber 28 from the interval between and, passes through the wind direction plate 53 together with the circulating cold air in the refrigerating chamber 28, and returns from the cold air suction port 46 into the cooling chamber 12.

On the other hand, the cool air cooled by the cooler 39 is blown upward by the blower 42 from the cool air discharge port 44 into the wind direction plate 52, and most of it flows into the refrigerating chamber 29 as it is, and a part of the central heat insulating partition plate. 22 enters the fluorescent lamp chamber 64 through the opening 67 at the lower end of the fluorescent lamp chamber 64 at the front end. The cold air flowing into the fluorescent lamp chamber 64 rises around the fluorescent lamp 63 mounted inside, and then flows into the refrigerating chamber 29 from the communication portion 66 at the upper end. The circulating cold air in the refrigerating chamber 29 passes through the wind direction plate 54 and returns from the cold air suction port 47 into the cooling chamber 12. As a result, the insides of the chambers 26, 27, 28, and 29 are cooled to a predetermined refrigerating temperature (for example, + 5 ° C.), and all of them are refrigerating chambers. At this time, the cool air discharged from the cool air discharge ports 43 and 44 is smoothly guided upward by the wind direction plates 51 and 52, so that the cooling temperature change chambers 26 and 27 and the upper part of the refrigerating chamber 29 are uniformly cooled.

Next, the dampers 57, 57 and 56, 56
When is closed, cold air does not flow into the cold temperature switching chambers 26 and 27. By making the heater H generate heat in this state, the inside of the cold temperature switching chambers 26 and 27 is used as a warming chamber kept at a predetermined temperature (for example, + 55 ° C. to + 65 ° C.). Further, the dampers 57, 57 are opened, only the dampers 56, 56 are closed, and only the heater H of the cold / hot switching chamber 26 is caused to generate heat, so that it is possible to make only the cold / hot switching chamber 26 a heating chamber. There is. At this time, the temperature inside the fluorescent lamp chamber 64 tends to rise due to the temperature influence from the cold / heat switching chambers 26 and 27 through the shade 61 and the heat generated from the fluorescent lamp 63 itself. Since the cool air from the lower opening 67 is rising around the fluorescent lamp 63, the temperature rise in the fluorescent lamp chamber 64 is suppressed,
As a result, the socket of the fluorescent lamp 63 is not deformed,
It is possible to prevent an electric leakage accident and a decrease in the illuminance of the fluorescent lamp 63.

Here, the magnet gasket 32,
33 and 34 are made of soft synthetic resin in a rectangular shape, and a wedge-shaped engaging portion is formed on the rear surface thereof as shown in FIG. 3, and the engaging portion is formed at the opening peripheral edge of each chamber 26, 27, 28. Each chamber 26, 2 is attached by engaging with the groove
The front openings 7 and 28 are respectively surrounded. In particular, on the front surface of the heat insulating partition plate 23 (same for 24),
The upper and lower two grooves 78, 79 are formed at intervals, and the gaskets 32, 33 (and 33, 34) are formed on the front surface of the heat insulating partition plate 23 (and 24).
9 is attached by engaging the engaging portion with 9. As a result, gaps 81, 81 are formed between the adjacent sides of the gaskets 32, 33, 34, respectively.

On the other hand, the display plate 77 is formed by cutting out a metal sash 83 on the periphery of the door 7 and inserting both sides into the cutout portion so as to be detachably attached to the back surface of the glass 86 of the door 7. Then, when the door 7 on the left side is closed, the gaskets 32, 33, and 34 come into close contact with the inner surface of the sash 83 of the door 7 by magnetic force, but the gaskets 32, 33 located on the front surface of the heat insulating partition plate 23 (24 are the same). The sides of (33, 34) are in close contact with the back surface of the display plate 77 as shown in FIG. As a result, the entire front surface of each gasket 32, 33, 34 is in close contact with the sash 83 of the door 7 or the display plates 77, 77 at the peripheral edge of the front opening of each cold / heat switching chamber 26, 27 and the refrigerating chamber 28, and each opening is independent. Since it is hermetically closed, the air flow between the cold temperature switching chambers 26 and 27 at the opening portion or between the cold temperature switching chamber 27 and the refrigerating chamber 28 is surely blocked. Further, when the door 7 is closed as shown in FIG.
Since the space 81 between 2, 33 (or 33, 34) serves as an adiabatic space, heat conduction other than air circulation is well blocked. As a result, the temperature effect between the chambers 32, 33, 34 is effectively blocked. In particular, when the cold temperature switching chamber 26 is used as a warming room and the cold temperature switching chamber 27 is used as a cold storage room,
When the cold / hot switching chamber 27 is used as a hot storage chamber, it is provided between the cold / hot switching chambers 26, 27 or between the cold / hot switching chamber 27 and the cold storage chamber 28.
Although the temperature difference between them is as high as 60 ° C. or more, in the present invention, since the heat insulating property in the gasket portion is improved as described above, it is possible to smoothly control the heat retention or cooling of each chamber and consequently contribute to energy saving. To do.

Further, since the gaskets 32, 33, 34 on the front surfaces of the heat insulating partition plates 23, 24 adhere to the rear surfaces of the display plates 77, 77, the gaskets 32, 33,
34 disappears from the front. Therefore, the design effect when the showcase 1 is viewed from the front is improved. If the display plate 77 is not provided, the gaskets 32, 33, and 34 are in close contact with the back surface of the glass 86 of the door 7, so there is no problem with the heat insulation performance.

[0021]

As described above in detail, according to the invention of claim 1, since the gasket is provided at the periphery of the opening of each chamber and surrounds each opening, the door is closed and the gasket is closed. In close contact, the openings of each chamber are independently sealed. Therefore, the communication between the adjacent chambers in the opening portion does not occur. In addition, a gap is formed between the adjacent gaskets, and this gap becomes a heat insulating space when the door is closed, so the heat insulating property in the opening between the adjacent chambers is greatly improved, and the temperature control To improve
In addition, energy can be saved.

In particular, according to the second aspect of the invention, in addition to the above, the gasket contacts the display plate provided inside the door, so the gasket cannot be seen from the front through the glass, and the design effect of the showcase is significantly improved. To do.
