DEVICE FOR PREVENTING FREEZING OF VERANDA DRAINPIPE, AND HOT AIR DEVICE COUPLER FOR PREVENTING FREEZING OF VERANDA DRAINPIPE

摘要

The present invention relates to a veranda drainpipe, and more particularly, to a device for preventing freezing of a veranda drainpipe. Hot air is supplied into a veranda drainpipe to prevent the veranda drainpipe from freezing in winter. A hot air discharge pipe is connected to the veranda drainpipe to supply hot air into the veranda drainpipe in a manner such that the hot air flows downward so as to prevent the veranda drainpipe and a joint between the veranda drainpipe and the hot air discharge pipe from being clogged by foreign substances or water.
