The present invention relates to an open type showcase for both cold storage and hot storage, and more particularly, it relates to an open type showcase for both cold storage and hot storage, in which a user can easily recognize the operation mode of a duct blocking plate installed to selectively block a duct by forward / The present invention relates to an open type showcase for both cold storage and hot storage, which is provided with a central handling and sliding structure of a duct blocking plate which can be smoothly operated by a simple pushing and pulling sliding method without using any additional thickness.

In general, an open type showcase is installed in a convenience store, a department store, or the like, and stores various goods inside the opened front side, circulates the cooled low-temperature air and stores it in a freshly refrigerated state. It is.

This open showcase ejects cooling air from top to bottom to form an air curtain to block the open front. This is to prevent the cold air from escaping from the storage room where the merchandise is displayed and to block the inflow of ambient air containing fine impurities. That is, the air curtain blows the compressed air from the top to the bottom and installs the suction port at the bottom to block the outside and the inside by making an air film. (Flow) of the air that has adjusted the temperature, humidity, and the like.

In addition, not only refrigerated goods are displayed, but also hot-spot products are required to be displayed together. Thus, an open-type showcase serving also as a refrigerator and a warming-up has appeared. That is, in order to serve both the refrigeration and the warming, a heater is installed in the shelf, and a shielding film is formed inside the duct of the duct through which the cold air flows, so that the refrigerator and the warming are combined.

An example of the structure of the open showcase that serves as both a refrigerator and a hot shop is Korean Register Room 20-0395162, Korean Registration Room 20-0408115, Korean Registration Room 20-0422037, Korean Registration Room 20-0422038, Korean Registration Room 20-0422039 And the like.

However, in the case of an open type showcase which serves both as a refrigerator and a warm room, the shelf space can be selectively used as a cold storage space and a warm space, but the duct shield is structurally structured inside the duct of the product, The duct blocking membrane is formed in the duct of the product when the refrigerator is used for the entire refrigeration, and thus the duct blocking membrane is opened. However, due to the structural limitation of structurally obstructing the flow of the cold air, And the performance of products such as a temperature deviation between the shelves becomes worse. As a result, there has been a structural limitation that the sales ratios of refrigerated products and hot-spot products displayed on the shelves can not be maintained even when the seasonal and regional differences are different. In the case of the function of the product, especially in the summer, when the entire shelf of the product is used for refrigeration, the above structural problems (that is, the structural problem of structurally obstructing the flow of cold air due to the fact that the duct- Limitations), adversely affecting the formation of the air curtains, and excessive temperature variations in the shelf owing to the occurrence of such problems, making it difficult for the product to maintain its excellent performance.

Accordingly, the applicant of the present invention has made it possible to selectively use the product display space as a refrigerator and a warm space as disclosed in Korean Utility Model Registration No. 04328573, thereby changing the display space in correspondence with seasonal and regional sales amounts of refrigerated and heated products And the back panel assembly is constructed to have a structure having a fluidity of assembly so that the size of the display space can be changed so that products of various sizes can be displayed at desired positions to maximize the efficiency of use of the display space, We have developed an open type showcase for both cold storage and hot storage, which is designed to maximize the product's performance by constructing a barrier plate on the shelf.

1, the shelf 11, the duct cover 13 and the blocking plate 12 are constituted by a single assembly, as shown in FIG. 2A, FIG. 2B, and FIG. 2B. However, in the open showcase disclosed in the official gazette No. 04328573, In order to move the blocking plate 12, the hand screws 14 fastened on both sides of the blocking plate 12 are released to release the restraint, the both hand screws 14 are held by both hands and are pushed or pulled simultaneously I had to give it. After the blocking plate 12 has been moved, the hand screw 14 has to be tightened again.

This method of operation is not only troublesome for the actual user but also difficult to recognize the operation method itself, often causing the user to make a claim to the manufacturer side without using the operation.
