DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a defrost water drainage device for a cooler for cooling a storage room.

[0002]

2. Description of the Related Art As one type of this type of defrost water drainage device,
A cover (duct member) that is disposed inclining below the cooler that cools the storage room, forms a cool air passage, and receives defrost water dripped from the cooler when the cooler is defrosted.
And a drain pipe provided at an inclined lower end of the cover to guide the defrost water to a drain passage, which is disclosed in, for example, Japanese Patent Application Laid-Open No. H11-108531.

[0003]

In the defrosting water discharger disclosed in the above-mentioned publication, a cold air guide member is disposed on the inclined surface of the cover so as to face the water inlet of the drainage pipe. Although various functions and effects can be obtained, the cool air guide member hinders the flow of defrost water to the inlet of the drain pipe. For this reason, there is a possibility that the amount of defrost water that freezes on the cover may increase, and this may also make it impossible to efficiently drain the defrost water from the cover to the drain pipe.

[0004]

A cover for receiving defrost water dropped from the cooler at the time, and a defrost water discharge device for a cooler including a drain pipe provided at an inclined lower end portion of the cover and guiding the defrost water to a drain passage, A part of the cover between the cooler and the drain pipe is provided with a wind direction plate for collecting cool air at a predetermined position, and a cool air discharge port is provided on the cover at a portion where the cool air is collected by the wind direction plate. A duct is provided corresponding to the discharge port, a fan motor for circulating cool air is arranged in the duct, and a water flow port for flowing the defrost water toward the drain pipe is provided at a downstream end of the wind direction plate. Is characterized by .

[0005]

In the defrosting water discharging device for a cooler according to the present invention, the defrosted water dropped on the cover can be collected by the flow of cool air collected at a predetermined location by the wind direction plate. The frost water can be made to flow as a water flow toward a drain pipe through a water inlet provided in the wind direction plate.
Therefore, the amount of defrost water that freezes on the cover can be reduced, and the defrost water can be efficiently drained.
