Abstract

PROBLEM TO BE SOLVED: To prevent a decrease in efficiency of drying and heating and keep the bather from being affected by a feeling of cool air by controlling the operation in a manner of effecting, besides ventilation of the bathroom under prescribed conditions, the heating of the dressing room simultaneously. SOLUTION: In a bathroom 1 an apparatus 3 having functions to effect ventilating drying and room heating is installed and in a dressing room 2 a dressing room-heating apparatus 4 is installed. To the bathroom 1 a temperature sensor 12 and a humidity sensor 13 are attached and to the dressing room 2 a temperature sensor 11 is attached. When during operation of the bathroom- ventilating/drying and room-heating apparatus 3 the temperature sensor 11 inside the dressing room 2 has detected a temperature not higher than a prescribed point, the dressing room-heating apparatus 4 is put in operation simultaneously by control by a controller 10. As a result, warm air in the dressing room flows into the bathroom 1 through gaps in the bathroom door and through a louver. Therefore, the efficiency of drying and room heating is prevented from decreasing and the bather can be kept from being affected by a feeling of cool air.

The operation control method for a bathroom ventilator according to the above 1, wherein the bathroom ventilator has both bathroom ventilation drying and heating functions. 3. 2. The operation control method for a bathroom ventilation device according to the item 1, wherein the bathroom ventilation device is a ventilation fan.

[0005] 4. 4. The operation of the bathroom ventilator according to the above item 1 or 2, wherein the device has a temperature sensor for measuring the temperature in the undressing room, and simultaneously operates the undressing room heating device only when the temperature measured by the temperature sensor is equal to or lower than a set temperature. Control method. 5. 4. The operation control of the bathroom ventilator according to the above 1, 2 or 3, wherein the bathroom ventilator has a temperature sensor for measuring the temperature in the bathroom, and simultaneously operates the undressing room heating device only when the temperature measured by the temperature sensor is equal to or lower than a set temperature. Method. 6. It has a temperature sensor that measures the temperature in the bathroom, and measures the temperature in the bathroom in chronological order immediately after starting the bathroom ventilation operation.
4. The operation control method for a bathroom ventilator according to the above item 1, 2 or 3, wherein the undressing room heating device is simultaneously operated only when the temperature rising gradient is equal to or lower than a predetermined value.

[0006] 7. The bathroom ventilator according to the above 1 or 2 or 3, which has a humidity sensor for measuring the humidity in the bathroom, and only when the humidity measured by the humidity sensor is equal to or higher than the set humidity, simultaneously operates the undressing room heating device. Operation control method. 8. It has a humidity sensor that measures the humidity in the bathroom, and measures the humidity in the bathroom in chronological order immediately after the start of bathroom ventilation operation.
4. The operation control method for a bathroom ventilator according to the above item 1 or 2, wherein the undressing room heating device is simultaneously operated only when the falling gradient of the humidity is equal to or less than a predetermined value. 9. A control device that can simultaneously control the bathroom ventilation device and the dressing room heating device under predetermined conditions.

[0007]

[Function] When the temperature in the undressing room is lower than the set value, when the undressing room heating device is operated simultaneously with the operation of the bathroom ventilator, the warm air in the undressing room passes through the gap in the bathroom door and the galley. It flows into the bathroom. As a result, the efficiency does not decrease during the drying and heating operation of the bathroom, and there is no feeling of cool air during the bathing.
