Abstract

PROBLEM TO BE SOLVED: To provide a multistage shelf type display case which clears up visually the upper part of a display case which is used to display cold storage foodstuff in a foodstuff store by eliminating a ceiling area and a canopy area and increasing the number of shelf boards effectively. SOLUTION: A cooler 8 is provided on the bottom of a rear surface duct 4b which is located at a site lower than a display shelf 9 on the lowest stage while a cold air outlet for the formation of an air curtain is provided at the position directly over the top of the rear surface duct 4b, thereby eliminating the need for a ceiling area which extends forward. The display shelf 9 is employed, which is narrower in the upper stages and wider in the lower stages. A large number of cold air outlet holes 3a, which supply the cold air in the rear surface duct 4b to each of the display shelves 9 in the storage, are bored in an internal panel 3 which forms the rear surface duct 3. A total flow rate of cold air supplied from the cold air outlet holes 3a is arranged to be larger than the flow rate of the cold air for the formation of the air curtain from the cold air outlet 5 provided at the position directly over the rear surface duct.

2. Description of the Related Art In a self-service food store such as a supermarket, a multi-tiered open showcase with an open front is widely used for displaying refrigerated food and fresh food. In the past, the cold air outlet portion of such an open showcase is generally provided at the tip of the ceiling panel portion projecting forward with the air curtain as the most important factor.

FIG. 3 shows an example of this conventional open showcase. The open showcase 21 for storing and displaying products such as foods at a low temperature is opened at the front and protrudes forward of the upper part. A ceiling part 22a, a back part 22b that covers the back, a bottom part 22c at the bottom, a bottom front part 22d that covers the bottom front, and a bottom side part that covers the bottoms on both sides
A case body 22 is integrally formed by filling a heat insulating material. Further, a duct 24 that circulates cool air is formed between each of these parts and the internal panel 23.

At the top end position of the case body 22,
The top panel 23a of the inner panel is provided with a cool air outlet 25 that rectifies and blows down cool air as an air curtain, and the cool air blown into the open showcase 21 is a cool air suction opening at the rear of the lower front surface portion 22d.

Therefore, it is necessary to lower the upper shelves more than necessary to set the shelves, and there is a problem that a large number of shelves cannot be installed (the above-mentioned semi-high case has a limit of two). Also, a mirror was needed to make the upper shelf look effective.

Therefore, the present invention is an open showcase used for displaying refrigerated food or the like in a food store or the like, which makes it possible to remove the ceiling part and the canopy part to clean the case upper part and effectively increase the number of shelves. You can
The object is to provide a multi-shelf open showcase that does not require an upper mirror or the like.

In order to achieve the above-mentioned object, the present invention forms a case main body with a heat insulating wall having an open front surface, and partitions the bottom surface and the back surface into the case main body. An inner panel forming a duct between the inner panel and a plurality of display shelves arranged inside the inner panel,
In an open showcase in which an air curtain is formed in the opening on the front of the case body by a cooler and a circulation fan provided in the duct to cool the in-compartment goods, the cooler provided in the duct is installed at the bottom display shelf. It is characterized in that it is arranged at a lower position and that a cool air outlet for forming the air curtain is provided at a position directly above the rear duct.

Further, according to the present invention, a plurality of cold air blow-out holes for supplying the cool air in the back duct to each display rack in the warehouse are formed in the inner panel forming the back duct, and the cold air blow-out holes are provided. The cool air flow rate supplied from the cooling air flow rate is set to be higher than the cool air flow rate for forming the air curtain from the cool air outlet provided directly above the rear duct. It is also characterized in that the lower tier is the widest. In addition, a transparent windshield plate was provided near the outside of the cool air inlet provided on the lower front part (panel part) of the case body, and the cooler was installed on the bottom of the rear duct below the lowest shelf or at the bottom. It is characterized in that it is provided at the bottom of the bottom duct below the lower shelf, or at both of them.

As described above, when the cold air outlet is provided directly above the rear duct and the ceiling panel is eliminated, the feeling of oppression is eliminated, the top shelf is easily visible, and the hot-selling products can be displayed. . In addition, since the uppermost shelf is well visible, the upper shelf can be set higher than the conventional case of the same height, and as a result, a larger number of shelves can be set.
