効果を奏するものである。The transparent door (6) of the upper case has two or three transparent plates (40) (41) (42) and - or two spacers (43) (44) as shown in Fig. 4. , one or two layers of heat insulation space (4) defined by each transparent plate and spacer
5) (46) and a heat ray reflective coating (4) with good visual light transmittance attached to the side surface of the heat insulating space of the outside transparent plate (40).
The main body is a multi-layer transparent plate (6A) consisting of 7), and is cooled by the cold air forcedly circulated inside the refrigerator (7). In addition to reducing heat conduction and reflecting heat rays in the long wavelength range such as infrared rays without impairing the see-through effect of the interior of the refrigerator (7) with the heat ray reflective coating (47), the refrigerator outer transparent plate (40) is intended to prevent dew condensation by increasing the temperature. In addition, as shown in Fig. 5, the transparent door (16) of the lower case (3) is mainly composed of a transparent plate (16A) with a heat ray reflective coating (50) with good visible light transmittance attached to the inner side surface of the refrigerator. radiant cooling is prevented by reducing the heat transfer of the cold air to the heat ray reflective coating (50) through the almost still air layer (39) formed between the cool air naturally convecting inside the refrigerator (18). In addition, the inside of the refrigerator (
It is intended to reduce the refrigeration load and prevent dew condensation on the transparent plate (16A) by reflecting heat rays without impairing the see-through effect of 18). Furthermore, the see-through window (17) has three transparent plates (60), (61), and (62) similar to the transparent door (6) as shown in FIG.
), spacers (63) (64), and heat insulating spaces (65) (
The main body is composed of a multilayer transparent plate (17A) consisting of a heat ray reflective coating (66) and a heat ray reflective coating (67), and has the same effect as the transparent door (6).

等を一切なくすことができる。According to the heating structure, the signboard (27) not only functions as a billboard for displaying the names of products stored in the refrigerator (7), but also directs warm air onto the surface of the transparent door (6). In order to function as the outer component of the hot air passageway (28), the hot air passageway (28) can be configured using both the signboard (27) and the duct cover (28A), which simplifies the configuration of the hot air passageway. In addition, the duct cover (28A), which together with the signboard (27) constitutes the hot air passage (28), forms the suction port (28b) that houses the propeller (29A) of the blower (29). ) can be used as a high-pressure chamber, so a predetermined wind pressure can be applied to the warm air blown out from the air outlet (28a) along the surface of the transparent door (6), and the duct cover (28A) is the widened part (28
The suction n (28b) in the hot air passage (28) is sloped low from B) toward both left and right ends.
The areas on both the left and right ends that are far from the air are tapered, making it possible to keep the wind pressure in the hot air passage (28) constant in the width direction, and as a result, the air blows out from the air outlet (28a) along the surface of the transparent door (6). A transparent door that can even out the wind speed distribution of warm air and prevent uneven wind speed distribution of warm air (6)
It is possible to completely eliminate concentrated heating of the transparent door (6) at extreme parts due to warm air, which causes dew condensation on the transparent door (6) and an increase in the refrigeration load through the transparent door (6).
