Low temperature showcase

Abstract

There is disclosed a low temperature showcase in which dew condensation occurring on transparent walls is efficiently decreased, whereby the lowering of visibility can be avoided, and a disadvantage that customer's clothes are made dirty can be suppressed. The low temperature showcase has a constitution in which insulating side panels are attached to the left and right sides of a main body having a display chamber and in which a machine chamber is disposed in the lower part of the main body outside the display chamber, each of the insulating side panels includes a see-through transparent wall and a side panel front cover which covers the front edge of this transparent wall, and this side panel front cover has a waste heat passage which communicates with the inside of the machine chamber and a space of the outer surface of the transparent wall.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a low temperature showcase in which insulating side panels are attached to the left and right sides of a main body including a display chamber therein and in which a machine chamber is disposed in the lower part of the main body outside the display chamber.[0002]This type of conventional low temperature showcase is installed in a store such as a convenience store or a supermarket, and has a constitution in which insulating side panels are attached to both side parts of a main body made of an insulating wall having a substantially U-shaped section to define a display chamber in the main body. Transparent walls such as glass plates are attached to the insulating side panels so that the inside of the display chamber can be seen through the walls from the sides of the main body (e.g., see Japanese Patent Application Laid-Open No. 2003-135228 (Patent Document 1)).[0003]In this case, the insulating side panels are substanti...

Benefits of technology

[0016]Moreover, since the waste heat from the machine chamber can be supplied to the outer surfaces of the transparent walls through the spaces between the outer surfaces of the transparent walls and the side walls of the side panel front covers, the waste heat can more effectively be directed and supplied to the outer surfaces of the transparent walls. Therefore, it is possible to increase the heating efficiency of the whole outer surfaces of the transparent walls, especially the front parts of the transparent walls, and it is possible to remarkably suppress the occurrence of the dew condensation.

[0017]According to the third invention, in addition to the above invention, each insulating side panel includes the side panel rear cover which covers the insulating wall from the outside and which is attached to the rear end of the side wall of the side panel front cover, and the abutment portion between the side panel front cover and the side panel rear cover is provided with the inclined surface directed outwards as the surface extends rearwards. Therefore, when such inclined surfaces are superimposed on each other, a waste heat leakage path in such a superimposed portion lengthens, to increase resistance, whereby it is possible to suppress a disadvantage that the waste heat leaks from such a superimposed portion.

[0018]In consequence, the waste heat from the machine chamber can more effectively be discharged to the spaces of the outer surfaces of the transparent walls through the waste heat passages, and a dew condensation preventing effect can be improved.

Problems solved by technology

However, in any constitution, the dew condensation occurs on the transparent walls of the insulating side panels, whereby there is a problem that the visibility of the inside of the display chamber through the transparent walls lowers, and there is another problem that when customers touch the transparent walls, clothes and the like are wetted.
