Therefore, bread crumbs and various impurities generated from the cakes displayed in the product quality room are introduced into the machine room through the ventilation openings, causing spoilage and mold, which is extremely unsanitary and smells from spoilage and mold. In addition to deterioration in the pears of the products on display, including the pear, freshness and texture are also deteriorated, which can even cause food poisoning.

In addition, in order to remove the condensed water and moisture generated in the evaporator, as illustrated in FIG. 7, a high-temperature and high-pressure pipe is installed inside the condensed water collecting container so that the condensed water collected in the condensed water collection container is Although it is evaporated by heat, noise is generated and the evaporation capacity is significantly lowered, and condensed water is collected in a separate container, and there is a hassle of emptying the container several times a day.

Moreover, the condensed water collected in the condensed water collecting container and the separate container causes serious water droplets to form not only in the machine room but also in the product display room, so that the machine room and product display room are always kept wet. It is severely contaminated and eventually deteriorates and damages the displayed products (cakes, etc.), which is extremely unsanitary.The high-temperature and high-pressure pipes are at risk of corrosion over time, and the refrigerant is lost due to the corroded high-temperature and high-pressure pipes, and the showcase is operated It causes even phenomena that cannot be caused.

In particular, in conventional showcases, a moisture removal fan is separately installed on the lower side of the front pane to remove moisture, so three various fans are installed.Thus, when the showcase is operated, three fans are operated simultaneously, so noise and vibration are excessive. The heat and wind are generated more than necessary, and not only the plate glass is heated, but also the heat is transferred to the inside of the showcase, which reduces the refrigeration effect.
