Description

Frost prevention showcase}

The present invention relates to a frost prevention showcase, and more specifically, to a frost prevention showcase capable of suppressing the occurrence of frost due to a temperature difference inside and outside the showcase window or effectively removing the generated frost.

Showcase, which is commonly encountered in the surroundings, refers to a glass case where products can be displayed and viewed.

Showcases are divided into various materials or shapes depending on how the product is sold. Selling customers face-to-face uses a closed case with the inside of the salesperson standing open and closed.

Self-service (self-service) or side-selling is often an open case that allows you to freely pick up the product without the glass on the side facing the customer.

On the other hand, the showcase is one of the products that have been widely used from the past, and the appearance or structure of the showcase is improving as the demand for the showcase increases.

For example, recently, products with a front surface of glass have appeared. When the front surface is made of glass, it is widely used in various types of stores because it has the advantage of being able to easily identify interior items without opening the glass.

However, any structure may cause frost on the glass of the showcase due to seasonal factors. Accordingly, various types of products or technologies are being grafted as a means to prevent frost.

It acts to block frost.

However, in the case of such a conventional technology, the structure is substantially too complex and the manufacturing cost may increase, and the device is large, so it is not easy to apply it to a cooling device such as a showcase, especially a showcase window made of glass.

On the other hand, on the one hand, various techniques for preventing frost in the showcase, for example, a technique in which the showcase glass is simply formed in a double layer, a technique in which the showcase glass is made thick, and a far-infrared-type glass heating technique, have been proposed.

However, since these technologies have structural limitations and are complex technologies, in most cases they do not provide adequate effects to prevent frost, so there is a need for anti-frost technologies as a showcase of a new concept that has not been previously known. do.
