Determination of dryness of textiles in a dryer
First Claim
1. A device comprising:
- a humidity sensor positioned outside a drying compartment of a dryer that senses humidity information concerning humidity levels associated with the dryer;
a temperature sensor that senses temperature information concerning a temperature associated with the dryer; and
a controller that determines dryness of items in the dryer based on the sensed humidity information and that counts dryer cycles of the dryer based on the sensed temperature information;
wherein the controller further detects start of a dryer cycle when the temperature information indicates that a temperature associated with the dryer remains at least as high as a threshold start temperature for at least a defined start period of time.

Abstract
A dryer monitor detects when textiles in a dryer are dry, detects when textiles in a dryer are overdry, and/or may count dryer cycles. The dryer monitor includes a humidity sensor, a temperature sensor, a controller and various status indicators. The humidity and temperature sensors may be located outside the drying compartment of the dryer. In the case of a clothes dryer, the humidity and temperature sensors may be located outside the drum of the dryer and may be located, for example, in the exhaust compartment of the dryer. The dryer monitor determines dryness of items in the dryer, and may also determine whether the items are overdry, based on humidity information received from the humidity sensor. The dryer monitor counts dryer cycles based on temperature information received from the temperature sensor.

15. An apparatus comprising:
-
a humidity sensor positioned outside a drying compartment of a dryer that senses humidity information concerning humidity levels associated with the dryer; a temperature sensor that senses temperature information concerning a temperature associated with the dryer; and a controller that determines dryness of items in the dryer based on the sensed humidity information and that counts dryer cycles of the dryer based on the sensed temperature information, wherein the controller further determines whether the items in the dryer are overdry a defined period of time after the controller determines that the items in the dryer are dry and tracks an amount of time the dryer continues to run after the items in the dryer are determined to be overdry. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
