Abstract
A humidistat including an air inlet defining a beginning of an airflow path through the humidistat, a humidity sensor for enabling measurement of the humidity of air flowing along the airflow path, a baffle, a heat source for heating air along a portion of the airflow path, the baffle and the heat source cooperating to define two zones in the humidistat, and an air outlet defining an end of the airflow path. During operation of the humidistat, the air temperature is higher in one zone than in the other zone, and the higher air temperature zone is downstream from the lower air temperature zone in the airflow path.
Claims20
A humidistat comprising:
- an air inlet defining a beginning of a fanless airflow path through the humidistat;
- a humidity sensor for enabling measurement of the humidity of air flowing along the airflow path;
- a baffle;
- a heat source for heating air along a portion of the airflow path;
- said baffle and said heat source cooperating to define two zones in the humidistat, wherein during operation of the humidistat, the air temperature is higher in one zone than in the other zone, and wherein the higher air temperature zone is downstream from the lower air temperature zone in the airflow path;
- and
- an air outlet defining an end of the airflow path.
A humidistat for regulating the humidity of a piano, comprising:
- an air inlet defining a beginning of a fanless airflow path through the humidistat;
- a humidity sensor for enabling measurement of the humidity of air flowing along the airflow path;
- a baffle;
- a heat source for heating air along a portion of the airflow path;
- said baffle and said heat source cooperating to define two zones in the humidistat, wherein during operation of the humidistat, the air temperature is higher in one zone than in the other zone, and wherein the higher air temperature zone is downstream from the lower air temperature zone in the airflow path;
- and
- an air outlet defining an end of the airflow path.
A humidistat for regulating the humidity of a piano, comprising:
- an air inlet defining a beginning of a fanless airflow path through the humidistat;
- a humidity sensor for enabling measurement of the humidity of air flowing along the airflow path;
- a baffle;
- electrical circuitry for having electricity flowing therethrough to heat air along a portion of the airflow path;
- said baffle and said electrical circuitry cooperating to define two zones in the humidistat, wherein during operation of the humidistat, the air temperature is higher in one zone than in the other zone, and wherein the higher air temperature zone is downstream from the lower air temperature zone in the airflow path;
- and
- an air outlet defining an end of the airflow path;
- wherein when the humidistat is in use, air flowing along the airflow path enters the humidistat through the air inlet, flows substantially downward through the lower air temperature zone, is heated by the electrical circuitry, flows substantially upward through the higher air temperature zone, and exits the humidistat through the air outlet.
A humidistat for regulating the humidity of a piano, comprising:
