Title:
DRYER AND ABSOLUTE HUMIDITY DIFFERENCE SENSOR
Document Type and Number:
WIPO Patent Application WO/2017/175257
Kind Code:
A1
Abstract:
Provided is a dryer in which detection accuracy is improved by directly detecting the humidity inside the dryer, which is free from overdrying and underdrying, and which enables easy installation of a humidity sensor. In the dryer 100 according to the present invention, the humidity of supply air on a supply path of a heat pump dryer unit 30 is directly detected by a first humidity detection sensor S1, while the humidity of exhaust air on an exhaust path is directly detected by a second humidity detection sensor S2. The first humidity detection sensor S1 and the second humidity detection sensor S2 are collectively disposed at one place, and are respectively provided with a first conduit line or a second conduit line for leading the supply air or the exhaust air to the corresponding sensor position. The sensors may be disposed collectively at one place on the supply path or the exhaust path, whereby installation work is made easy while reducing space required for installation. Further, the environmental temperatures of the two humidity sensors can be deemed equal; thus, when relative humidity sensors are to be used, temperature detection for the purpose of conversion into absolute humidity needs to be performed only at one place.
