Exhaust structure from dryer in apartment building

Abstract

The present invention relates to an exhaust structure from dryers in an apartment building including at least one riser tube running vertically crossing stories of the apartment building, a plurality of branch tubes branched from the riser tube to apartments on each of the stories for guiding exhaust gas from the apartments to the riser tube, and a fan mounted to a top of the riser tube and to be driven for making a pressure distribution in the riser tube to be the same with a pressure distribution on an outside of the building, substantially.

Description

[0001]This application claims the benefit of Korean Patent Applications No. 10-2006-0110194, filed on Nov. 8, 2006 and No. 10-2006-0110151, filed on Nov. 8, 2006, which are hereby incorporated by reference in their entireties as if fully set forth herein.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a structure for discharging gas from laundry dryers in many apartments to an outside of a apartment building, and a laundry dryer manufactured suitable for such a structure, and more particularly, to an exhaust structure suitable for discharging gas from laundry dryers, taking characteristics of the gas from the laundry dryers into account.[0004]2. Discussion of the Related Art[0005]Starting to make an appearance in large cities, the apartments are becoming a general residential type, currently. Though the apartment buildings have had below 15 stories mostly, apartment buildings even over 20 stories are constructed, and apartment buildin...

AI Technical Summary

Benefits of technology

[0019]Moreover, each of the plurality of branch tubes has at least one of a backflow preventive damper for preventing the exhaust gas

Problems solved by technology

Moreover, vortex becomes the more intensive as the height of the high rise apartment building becomes the higher.

In the case of the high rise apartment building, it is difficult to open the windows for venting the apartment due to such wind.

However, the strong wind rushing to a discharge opening at the top of the riser tube in the high rise apartment building interferes smooth discharge of the gas through the riser tube by using the non-power fan.

Moreover, because opening the window for venting the apartment is difficult, in general, a dryer is provided.

Of the dryers, a dryer which burns fuel for generating hot air produces harmful exhaust gas including carbon monoxide gas in addition to general exhaust gas.

Therefore, the related art high rise apartment building has a problem in that such exhaust gas can not be discharged.

Moreover, the related art exhaust structure is not suitable for the exhaust gas from the dryer, having characteristics that much moisture, much foreign matters, such as lint, and harmful substances, such as carbon monoxide, in a case the hot air is generated by burning fuel, are contained, and amount is large because the laundry dryer is used for a long time.
