[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a showcase for keeping goods cool, in which a frame forming a product take-out opening is made of metal.
[0002]
[Prior art]
Conventionally, four sides including the door of the product storage room for exclusive use of refrigeration or for both refrigeration and warm storage, or the five surfaces with the top surface added to this, are made of glass plates, and the cold products etc. in the product storage room can be seen from the outside. Such a showcase is generally used. In such a showcase, the frame of the product take-out opening opened and closed by the door is formed by assembling the left and right vertical frames made of metal and the horizontal frame above the door side in a gate shape. Each vertical frame supports the front ends of the left and right glass plates via a PVC frame material or the like, and the horizontal frame supports the front ends of the top plate.
[0003]
The support structure of the horizontal frame will be described with reference to FIG. In the figure, 50 is a door, 51 is a thin metal plate attached to the door 50, 52 is a door packing containing a magnet, and 53 is a door packing fixing member for fixing the door packing 52. Although not shown, the horizontal frame 40 is provided between the upper portions of the vertical frames, and supports the door packing fixing member 53 by screws or the like.
[0004]
[Problems to be solved by the invention]
However, the conventional showcase has a structure in which the outer side surface of the horizontal frame 40 above the door side is exposed to the outside and directly contacts the outside air. Therefore, there is a problem that dew condensation easily occurs on the outer surface of the horizontal frame 40. In order to prevent this, the dew-proof heater 41 is conventionally installed on the inner surface of the horizontal frame 40, but this increases the cost of parts of the showcase, increases the number of assembling steps, or increases the running cost. Such an adverse effect has occurred.
[0005]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a showcase in which dew condensation hardly occurs on a horizontal frame above a door side and which is advantageous in cost.
[0006]
[Means for Solving the Problems]
The showcase according to the present invention has a vertical frame in which a metal frame forming the product outlet is provided on the left and right sides with a product outlet that is opened and closed by a door on a side surface of a product storage room capable of keeping the product cool. In a showcase composed of a horizontal frame provided between vertical frames, the horizontal frame is wrapped inside a frame formed of a resin member, and the horizontal A frame is arranged, and a hollow portion is provided inside the frame to separate the horizontal frame from the product storage room. According to the present invention, the hollow portion acts to block heat conduction from the product storage room to the horizontal frame. This suppresses the occurrence of dew condensation inside and outside the horizontal frame.
[0008]
The product storage room includes a refrigerator / hot storage switching type.

BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a perspective view of a showcase according to one embodiment of the present invention. 2 and 3 schematically show the characteristic components and the like of this showcase. FIG. 2 is a partial cross-sectional view taken along line AA of FIG. 1, and FIG. It is an exploded perspective view of a frame. The showcase 1 is divided into an upper product storage room 2 and a lower machine room 3, and a cooling unit (not shown) for cooling the inside of the product storage room 2 is arranged in the machine room 3. The product storage room 2 is defined by a front transparent door 2a, left and right and rear transparent side plates 2b, 2c, 2d and an upper transparent top plate 2e, each of which is made of a glass plate. Each side end of the transparent side plates 2b, 2c, 2d is fitted and held in a vertical groove of a vertical frame member 2s made of resin, which is erected on the left and right sides on the door side and the left and right sides on the rear side. A metal vertical frame (not shown) is inserted into each vertical frame member 2s as a core material, and each vertical frame is connected to and supported by a frame frame (not shown) forming the machine room 3.
[0011]
A horizontal frame 10 made of metal and having an L-shaped cross section as shown in FIG. 2 is provided between the upper portions of the vertical frames on the left and right sides of the transparent door 2a, and the horizontal frame 10 is covered by a frame 20 as a resin member. . The front end of the transparent top plate 2e of the product storage room 2 is supported by the horizontal frame 10 via the top frame member 2t that receives the front end and the frame 20. The gate-shaped horizontal frame 10 and the vertical frame substantially form a frame of a product outlet in front of the product storage room 2. In FIG. 2, reference numeral 30 denotes a door packing, and the door 2 a seals a product take-out opening of the product storage room 2 by adsorption of a magnet 31 put in the front end of the door packing 30 and a thin metal plate 32 fixed to the door 2 a side. . The rear end of the door packing 30 is fixed to a door packing fixing member 33, and the door packing fixing member 33 is fixed and supported by a protrusion 22 protruding below the frame 20 by screws or the like.
[0012]
The frame 20 is a substantially rectangular tube-shaped member in which a hollow portion 21 capable of accommodating the horizontal frame 10 with sufficient room is formed. The horizontal frame 10 has outer surfaces 11a and 11b formed on the front surface 21a and the upper surface of the hollow portion 21. It is housed in the hollow part 21 so as to be in contact with 21b. Therefore, the outer surfaces 11a and 11b of the horizontal frame 10 are not exposed to the outside O, and dew condensation hardly occurs on the outer surfaces 11a and 11b. A hollow portion 21 remains on the inner side surfaces 12a and 12b of the horizontal frame 10, and the hollow portion 21 is located between the inner side surfaces 12 a and 12 b of the frame 10 and the inside of the product storage room 2. Therefore, the hollow portion 21 acts to block heat conduction from the inside of the product storage room 2 to the horizontal frame 10, whereby the occurrence of dew condensation on the outer side surfaces 11 a and 11 b of the horizontal frame 10 is more reliably suppressed, and The occurrence of dew condensation on the inner side surfaces 12a and 12b of the horizontal frame is also suppressed.
[0013]
In the above embodiment, an example in which the hollow portion 21 is formed in the frame 20 has been described. However, as shown in the cross-sectional view of FIG. 4 in the present invention, portions common to FIG. 2 are denoted by the same reference numerals. This also includes a mode in which the horizontal frame 10 'is densely covered with the frame frame 20'. Even in this mode, dew condensation on the horizontal frame 10 'can be effectively suppressed.
[0014]
【The invention's effect】
As described above in detail, in the showcase according to the present invention, by enclosing the horizontal frame above the door side with the resin member, the horizontal frame does not directly come into contact with the outside air, so that dew condensation hardly occurs on the horizontal frame. can do.
[0015]
Also, by providing a hollow portion in the resin part between the horizontal frame and the product storage room, heat conduction from the product storage room to the horizontal frame is reduced, which further reduces condensation on the horizontal frame. Generation can be suppressed.
[0016]
Furthermore, since the conventional dew-proof heater required to prevent dew condensation on the horizontal frame is not required, the number of parts and the number of assembling steps of the showcase can be reduced, and the running cost can be reduced. Can be
