Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-humidity and low-temperature storage for keeping the storage chamber at a high humidity and a low temperature by cooling the outer surface of the storage chamber defined inside the heat-insulating box body with cold air.

[0002]

2. Description of the Related Art As a conventional high humidity and low temperature storage, an inner box made of a heat conducting material is fixedly mounted on a heat insulating box with a certain space between the heat insulating box and the inner box. An evaporator and a cold air circulation fan are installed in the space (hereinafter referred to as a cooling space), and the cool air is circulated in the cooling space to cool the outer surface of the inner box and indirectly connect the storage chamber defined inside the inner box. Some are designed to be cooled.

By the way, in such a high-humidity and low-temperature storage, when the inner box is indirectly cooled, dew adheres to the inner surface of the inner box due to the water content of the stored product or the water content of the outside air that enters when the door is opened and closed. This dew accumulates on the bottom of the inner box. For this reason, conventionally, as disclosed in, for example, Japanese Patent Laid-Open No. 2-272286, the bottom surface of the inner box is inclined, and the drain discharge holes formed in the bottom surface discharge the dew to the outside of the refrigerator. .

[0004]

However, in such a conventional high-humidity and low-temperature storage cabinet, when the bottom of the inner box is inclined and the dew is discharged in this way, when the inclination angle of the bottom is small, the bottom is inclined. There was a drawback that the dew accumulated in the above did not completely flow to the drain discharge hole, and the dew could not be discharged smoothly.

Therefore, the dew is guided to the drain discharge hole by increasing the inclination angle of the bottom surface. However, when the inclination angle of the bottom surface is increased in this way, the dew is discharged from the bottom surface of the inner box and the outside. Since the dead space generated between the box and the box becomes large, there is a problem that the effective space inside the box becomes small.

An object of the present invention is to provide a high-humidity, low-temperature storage cabinet capable of smoothly discharging dew without damaging the effective space inside the cabinet.

[0007]

The present invention provides a high-humidity low-temperature storage for cooling the outer surface of a storage chamber defined inside a heat-insulating box with cool air to keep the storage chamber at high humidity and low temperature. A side dew receiver is provided at a lower portion of both side walls of the storage chamber so as to incline toward the rear wall of the storage chamber, and a side dew receiver for receiving dew attached to the both side walls, and a lower portion of a back wall of the storage chamber. A rear dew receptacle that communicates with each of the side dew receptacles and is disposed at a low inclination toward the center of the storage chamber to receive dew from the side dew receptacle and dew attached to the back wall. And a water collecting portion which is formed on the bottom surface of the storage chamber, receives the dew from the rear dew receiving portion, and has a drainage port.

Further, according to the present invention, in the high humidity low temperature storage for keeping the storage chamber at high humidity and low temperature by cooling the outer surface of the storage chamber defined inside the heat insulating box with cold air, the inside of the storage chamber is attached. While forming a slight interval for accumulating dew, a drain plate is provided which drops dew accumulated in the gap at a pointed insertion part projecting on the lower surface and inserted into the discharge port provided on the bottom surface. It is provided above the bottom of the storage chamber.

Further, according to the present invention, a large number of drainage holes are formed in the drainage plate, and the drainage plate is kept slightly spaced from the bottom surface of the storage chamber by a push-down portion protruding downward when the drainage holes are formed. It is something that is supported.

[0010]

As a result, the dew adhering to both side walls of the storage chamber defined inside the heat insulation box body is disposed at the lower portions of both side walls so as to be inclined downward toward the rear wall of the storage chamber. After being received by the receiver, it can be received by the rear dew receiver, which is arranged on the back wall of the storage chamber with a low inclination toward the center of the storage chamber and communicates with the side dew receivers.

The dew received by the rear dew receiver is attached to the back wall together with the dew received by the rear dew receiver.
After the water is collected in the water collecting portion formed on the bottom surface of the storage chamber, it can be drained from the drain port provided in the water collecting portion.

Further, a drain plate is arranged above the bottom surface of the storage chamber so as to form a small space for accumulating the dew attached to the storage chamber, and an insertion portion having a sharp tip provided on the lower surface of the drain plate. The dew accumulated in the gap can be dropped by inserting into the discharge port provided on the bottom surface.

Further, while a large number of drainage holes are formed in the drainage plate, the drainage plate can be supported at a slight distance from the bottom surface of the storage chamber by a push-down portion protruding downward when the drainage holes are formed.
