Japanese Patent JP7458851
Kind Code:
B2
Abstract:
To provide a bathroom heating dryer capable of detecting abnormality of a filter due to clogging separately from the abnormality of a heat exchanger due to clogging.SOLUTION: The bathroom heating dryer comprises: a heat exchanger where a heat medium heated with a heat source machine flows therein; a filter which is installed at an air inlet of a bathroom; a circulation fan which has a fan motor and circulates air heated through the heat exchanger in the bathroom; a first temperature sensor which is installed on the heat exchanger at a side of a heat medium inlet and detects a temperature of the heat medium; a second temperature sensor which is installed on the heat exchanger at a side of a heat medium outlet and detects the temperature of the heat medium; and a control section which determines abnormality of the filter due to clogging thereof and abnormality of the heat exchanger due to clogging thereof. The control section individually determines the abnormality of the filter and the abnormality of the heat exchanger on the basis of a temperature difference between a first temperature detected through the first temperature sensor and a second temperature detected through the second temperature sensor and a current value A or a power value of the fan motor.SELECTED DRAWING: Figure 3
