And a bottom floor panel 36b.

[0004] The airflow of the cool air in the upper case 33 is blown downward from the outlet 43 in the ceiling, and the display shelf 4 is opened.
The food or the like placed and displayed on 4a, 44b, 44c is cooled, and a duct 46 (under-floor duct 46a, rear surface) formed between interior panel 37 and heat-insulating panel box 35 from suction port 45 on the floor. The duct 4b is forcibly drawn into the ceiling duct 46c), cooled by a cooler (not shown), and
6, the air is blown out from the air outlet 43 again and circulated. 47 is a door provided at the opening of the storage room 41 of the upper case 33.

On the other hand, the air flow of the cool air in the lower case 34 is supplied to an air outlet 48 provided in the upper part of the rear part of the case 34.
The food and the like which is blown out from the front and is placed and displayed in the flat storage room 42 formed by the front interior panel 38 is cooled in an air blanket state, and the front suction port 49 is provided.
Thus, the duct 50 (the underfloor duct 50a, the back duct 50a) formed between the interior panel 38 and the heat insulating panel box 36 is formed.
b) is forcibly attracted to the inside, is cooled by a cooler (not shown), and is blown out from the outlet 48 again through the duct 50 and circulated.

Next, FIGS. 5 to 8 show the structure of end frames 39 and 40 at both ends in the horizontal (left and right) directions for supporting the heat insulating panel boxes 35 and 36 of the upper case 33 and the lower case 34. FIG. 6 and 7 show the left end frames 39 and 40, and the right end frame has a structure symmetrical to the left end frames 39 and 40 shown in the figure.

First, the end frame 3 of the upper case 33
9 has a substantially U-shaped cross section, and forms an edge toward the center of the case 33.
a and the lower floor end frame 39c are welded and fixed on the upper and lower ends of the back end frame 39b.
Next, the end frame 40 of the lower case 34 has a substantially inverted L-shaped cross section, the upper side forms an edge toward the center of the lower case 34, and the end frame back plate 40b is placed on the floor end frame 40a. It has a structure in which the end faces are welded and fixed.

As shown in FIG. 5, when the upper case 33 is mounted on the upper part of the lower case 34, the lower case 34 is used as a reinforcement to support the upper case 33 when the upper case 33 is assembled to the upper part of the lower case 34. Is provided with an upper case support reinforcing member 51. FIG. 8 shows the upper case support reinforcing member 51. FIG. 8 shows a structure symmetrical to the reinforcement member 51 in the left direction. The reinforcing member 51 has an angle shape, and supports the upper case 33 in the front-rear direction (the upper side portion 51a in direct contact has a channel shape in cross section,
The upper case 33 is fixed by the fastening screw. The cross section of the other side portion 51b of the angle has an L-shape, and several places on the rear surface thereof are fixed to the lower case 34 and the base with tightening screws.

[0009]

As described above, in the conventional open showcase, the upper case and the lower case have independent storage rooms, and the respective heat-insulating panel boxes and end frames are separately and independently provided. Therefore, when assembling the upper case to the upper portion of the lower case, the upper case has to be assembled with an upper case support reinforcing member as a reinforcement to support the upper case. Therefore, the number of parts is large and the number of man-hours for assembling is inevitably increased, so that the assembling efficiency is low and the manufacturing cost is high. The present invention has been made in view of the above problems, and has as its object to provide an open showcase that is durable, has a small number of parts, has a reduced number of assembly steps, and has a low manufacturing cost.

[0010]

In order to achieve the above object, in the open showcase of the present invention, an opening is formed in the front of the compartment, and the inside of the compartment is divided into upper and lower upper and lower cases. And an open showcase in which the lower case independently forms a storage room with the respective heat-insulating panel boxes and interior panels and the respective end frames at both lateral sides, wherein the heat-insulating panel boxes of the upper case and the lower case are provided. The end frame and the end frame are integrated into a box having a substantially U-shaped cross section, and an intermediate panel is provided at a substantially intermediate position by dividing the upper and lower parts. The intermediate panel also serves as a floor panel of the upper case and a ceiling panel of the lower case, and furthermore, the heat insulation panel boxes of the upper case and the lower case have a common substantially U-shaped cross-section end. It is supported by a frame, and the intermediate panel is substantially at an intermediate position in the vertical direction of the end frame, and is supported by an intermediate frame attached to the end frame protruding forward.

By adopting the above structure, the heat insulating panel box and the end frame of the upper case and the lower case are respectively integrated, so that the upper case supporting and reinforcing member required conventionally is not required, and the assembling efficiency is improved. And it became possible to produce it cheaply.
