A structure is disclosed in which the storage chamber is provided with a bottom plate having both an air outlet and an air inlet, and cools at least the area below the partitioning member of the storage chamber by forced circulation of cold air.

(C) Problems to be Solved by the Invention In the above-mentioned prior art, since a partitioning member is disposed in the storage room to divide the storage room into upper and lower halves, the light from the light source of the lighting room is directed downward from the partitioning member of the storage room. A problem arose in that the product did not reach the refrigerated area, and the product display effect in this refrigerated area became extremely poor.

(d) Means for Solving the Problems In order to solve the above problems, the present invention provides an elongated fluorescent lamp 50 at the bottom of the partition member 21 horizontally and diagonally when viewed from the bottom (or plane).

It is composed of four metal side plates 26 arranged on four sides, and houses therein a refrigerant compressor 27, a condenser 28, and a blower 29, which constitute a refrigeration cycle together with the cooler.

The partitioning member divides the storage chamber 3 into upper and lower halves, and includes upper and lower metal plates 30 and 31 that separate opposing end surfaces from each other, and a foam insulation material such as hard polyurethane filled between these plates. It is mainly constituted by a material 32, and has a hollow door contact member 33 on the front surface against which the gaskets 17 of both transparent doors come into contact, and a seal member 34 made of heat-resistant resin on the back surface that contacts the transparent wall 15B. Reference numerals 35 and 36 indicate opening/closing devices made of heat-resistant resin that are movable in the left and right directions and are disposed on the left and right sides of the partitioning member, and have an upper wall 37 that overlaps with the upper plate and an outer edge that overlaps with the lower plate and extends outward. A lower wall 38 having a fin piece 38A, and a rising side 39 facing the side surface of the partition member and extending upward.
A groove 4 is formed between the vertical wall 39 having the shape A and the lower wall.
0 and a guide wall 41 having a knob 41A on the lower surface. 42 is the rising edge 3
By engaging the upper end with 9A, the vertical wall 39
This is a display board that covers the outside. Reference numerals 43 and 43 denote engaging members fixed to the lower surface of the partitioning member 21, and the guide pieces 44 thereof are respectively inserted into the grooves 40 of the opening/closing device. When the opening/closing device is closed as shown in FIG. 1, it hits the transparent wall 15C or 15D and completely separates both the upper and lower regions of the storage chamber 3, while creating a heat insulating space 45 between the upper, lower, and hanging three walls 37, 38, and 39. , 46, and the storage chamber 3 is spaced apart from the transparent wall 15C or 15D when opened as shown in FIG.
Flow passages 47 and 48 are formed to communicate both the upper and lower regions.

Reference numeral 49 denotes an elongated recess formed diagonally in the lower wall of the partitioning member, 50 an elongated straight tube fluorescent lamp housed in this recess and suspended from the partitioning member 21 by a hanger 51; is an elongated cover made of transparent resin that is fixed to the partition member 21 and protrudes below the lower surface of the partition member to cover the fluorescent lamp, and the fluorescent lamp and the cover are arranged horizontally and diagonally when viewed from the bottom. It is located in Along with the placement of this cover, this cover and
The distance L formed between the air outlet 10 and the transparent wall 15C adjacent to the air outlet 10 gradually widens from the back side toward the opening 16, that is, toward the transparent door 19B.

Reference numeral 53 denotes a hot plate that is slidable in the front and back direction and is installed on two rails 54 and 55 fixed to the upper surface of the partitioning member 21, and includes an electric heater 56, a thermostat 57 that controls the supply of electricity to the electric heater,
The main body is composed of a case 59 made of a heat transfer plate that houses an overheat preventer 58, and includes a handle 60 made of heat-resistant resin that also serves as a decoration and covers the front part of the case, and a guard 61 for preventing the product from falling over. ing. The lower wall of the case has a V that accommodates the upper end of the rail.
Shape guide paths 62, 63 are formed, and narrow grooves 64, 65 of the rails 54, 55 are formed on both sides of the guide paths.
A pair of engaging pieces 66 and 67 are attached to the hot plate 53 to prevent the hot plate from floating when the hot plate 53 is pulled out. As shown in FIG. 6, both rails are provided with hot plates 53.
a stopper 68 that regulates the sliding width in the front-rear direction;
69 is installed.

The show case converts the entire area of the storage room 3 into a refrigerated area, or the area above the partition member 21 into a hot storage area and the area below into a refrigerated area by the opening and closing operations of the opening/closing devices 35 and 36. That is, when the opening/closing devices 35, 36 are opened, the forced circulation cold air passes through the flow paths 47, 48 as shown by the arrows in FIG. As shown by the arrows in FIG. 1, the forced circulation cold air is prevented from flowing above the partition member 21 by the opening/closing devices 35 and 36, and at the same time, the electric heater 56 of the hot plate 53 is energized. The upper area of the member 21 serves as a hot storage area, and the lower area serves as a refrigerated area.

According to such a configuration, the area below the partitioning member 21 where the light from the light source 9 of the illumination room 2 is blocked can be illuminated with the light of the elongated fluorescent lamp 50 disposed at the lower part of this partitioning member. The fluorescent lamps are arranged horizontally and diagonally, with both ends located near the two diagonally opposing columns 14B and 14C, so that the range of illumination by the direct light of the fluorescent lamp 50 is Not only that, but also the illumination range of the reflected light by each of the transparent walls 15A to 15D is expanded, and the display effect can be improved. Further, a translucent cover 5 covering the fluorescent lamp 50 is provided.
2 are also arranged diagonally, so the partition member 21
The cool air flowing along the lower surface of the compartment member 21 hits the cover 52 and is directed diagonally downward, thereby promoting cooling of the products displayed directly below the partition member 21.

Moreover, the distance L between the transparent wall 15B and the cover 52
By making the cover 52 wider as it approaches the transparent door 19B, the cover 52 has the effect of directing cold air downward, and also has the effect of directing the wind to flow a lot of cold air in the direction of the transparent door 19B. The time required for the temperature near the warmed opening 16 to drop to a predetermined value after the door is closed becomes shorter.

(G) Effects of the Invention Since the present invention is configured as described above, the following effects are produced.

By arranging the elongated fluorescent lights horizontally and diagonally when viewed from the bottom at the bottom of the partition member, both ends of the fluorescent lights are located near the diagonally opposing columns, and as a result, The illumination range of the direct light of the fluorescent lamp is widened, and the illumination range of the reflected light from the transparent wall is also widened, so that the product display effect can be improved.

Since the cover covering the fluorescent lamp directs the cold air flowing along the lower surface of the partition member diagonally downward,
The cooling effect of the products displayed below the partition member is improved.
