Description

[Detailed description of the invention] This project relates to a show case that prevents condensation on transparent doors using warm air.The purpose of this project is to install a fluorescent lamp ballast for storage room lighting in the aisle and use it as a hot air source. , and may reduce the refrigeration load inside the refrigerator.

Below, an example of the present invention will be explained with reference to Fig. 1.
Reference numeral 1 denotes a case whose main body is composed of an insulating wall 2 having an opening 3 for storing and taking out products at the front and a rotatable transparent door 4 for freely opening and closing this opening. A cold air passage 8 in which a partition plate 5 is arranged at an appropriate interval from the inner wall and a cooler 6 and a blower 7 are installed; a storage room 11 provided with a plurality of shelves 9 and a fluorescent lamp 10 for illumination; Opposite blowout and suction ports 12 and 13 are formed at both upper and lower ends of the inside of the opening, and the cold air that has been heat-exchanged by the cooler is forcedly circulated as shown by the arrow with the blower 7, thereby allowing air to flow inside the opening 3. The storage room 11 is cooled by forming a low-temperature air curtain. Reference numeral 14 denotes a hot air passage formed by arranging a cover plate 15 at an appropriate distance from the outer wall of the heat insulating wall;
7 is formed on a cover plate 15, and a ballast 18 of the fluorescent lamp for illuminating the storage room and a blower 19 are disposed inside, and the heat radiated from the ballast 18 is used as warm air as shown by the arrow to blow the surface of the transparent door 4. To prevent dew condensation on the surface of the blowout transparent door 4 along. The stabilizer is provided within the passage 18 on the outlet side. Reference numeral 20 denotes a flow divider plate which also serves as a rectifying plate and is disposed upstream of the air outlet 16, which allows high temperature hot air generated by the heat radiation of the stabilizer 18 to flow in contact with the transparent door 4, and lower temperature warm air ( protective airflow).

According to such a configuration, the ballast 18 can be used as a heat source for preventing condensation on the transparent door 4, and at the same time, the heat dissipation of the ballast 18 itself can be promoted.
is arranged in the passage 14, so the refrigeration load on the storage chamber 11 can be reduced by that length.

Incidentally, FIG. 2 shows another embodiment of the present invention, in which hot air is blown from the bottom to the top of the transparent door 4.

As mentioned above, this proposal includes a transparent door that can be opened and closed to open and close the opening for storing and taking out products formed on one side of the insulation wall, and a cover plate placed at an appropriate distance from the outer wall of the insulation wall. A ballast for a fluorescent lamp for illuminating a storage room and a blower are disposed inside, and a passageway having an air outlet located at one end outside the opening is provided, and the blower generates forced ventilation. The ballast is used as a heat source to prevent condensation on the transparent door. At the same time, it is possible to effectively utilize the heat dissipation of the ballast, promote the heat dissipation of the ballast itself, and prevent a decrease in the illuminance of the fluorescent lamp.In addition, the refrigeration load of the storage room with the ballast placed in the aisle can be reduced. It can be reduced.

Claims (1)

[Scope of utility model registration request] It is formed by a transparent door that can be opened and closed to open and close an opening for storing and taking out products formed on one side of the insulating wall, and a cover plate placed at an appropriate distance from the outer wall of the insulating wall. is provided with a ballast for a fluorescent lamp for lighting the storage room and a blower, and a passageway having an outlet located at one end of the outside of the opening, and the ballast is provided with a passageway having a blower outlet located at one end outside the opening. This case is characterized by being heated by heating the air and blowing it out as warm air from the air outlet along the surface of the transparent door.
