发明名称 Dryer vent check strip
摘要 A vent check strip for checking a dryer or a vent pipe connected to a dryer. The vent check strip has a temperature sensitive area that changes its color at a threshold temperature within a working temperature range of the dryer when the dryer functions normally. The vent check strip can be placed inside the dryer or the vent pipe so that after the dryer is turned on to perform its normal drying function for a period of time until the dryer reaches the working temperature range, the vent check strip can be retrieved for examination. If the vent check strip does not change its color, then it indicates that the dryer is malfunction or the vent pipe is clogged, kinked, broken or otherwise damaged and needs to be serviced.
