Abstract

PROBLEM TO BE SOLVED: To effectually simultaneously achieve ventilation and drying in a bath room by mounting a swing louver unit, providing an axially movable driven changeover drum inside a ventilating hole to change over modes. SOLUTION: When an apparatus 1 is set to drying, a heater 3 becomes on, and a changeover drum 4 swings at a rate of about 20 times for each minute between A and B positions. In synchronism with this, a louver of a swing louver unit 7 also swings. Accordingly, high temperature air 6 is exhausted to the outside of a house in a pulsating manner without lowering temperature in the bath room to promote drying of cloths. When the changeover drum 4 swings to the A position, warm air into the bath room is blown out in the direction A while the drum 4 swings to the position B, the warm air into the bath room is also blown out in the direction B9, the drying is promoted with this warm air. In a heating mode, the changeover drum 4 fully closes an exhaust port to the outside so that air from a fan 2 is heated with a heater 3, and is blown out into the bath room as warm air.

2. Description of the Related Art A conventional bathroom dryer is a combination of two fans, one for warm air in the bathroom and one for exhaust from the bathroom to the outside, and one fan for the exhaust part. There is a type that uses the hot air blowing in the bathroom and the exhaust air of the outdoor by switching the valve to the, but the former type has a problem in cost, the latter type is Ventilation and warm air drying, which are advantages of the previous type, cannot be performed at the same time.

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that it is a type using only one fan, and it is possible to more efficiently perform ventilation and warm air drying in the bathroom at the same time.

[0004]

As means for solving this problem, the present invention uses a swing louver unit in combination with a controllably driven axially movable drum instead of using a valve. Is to be solved by.

[0005]

[Function] With a single fan, an axially movable drum that is controllably driven is installed in the exhaust part, and a swing louver unit is installed in the exhaust port inside the bathroom, which efficiently ventilates and dries the bathroom. Are to be carried out at the same time.

EXAMPLE First, referring to FIG. 1, the drying mode will be described.
When the device 1 is set to dry, the heater 3 is turned on, the switching drum 4 swings between the A position and the B position at a speed of about 20 times per minute, and in synchronization with the swing,
The louver 12 of the swing louver unit 7 also swings. Therefore, the high-humidity air 6 is pulsatively exhausted to the outside without lowering the temperature in the bathroom, and the clothes dried in the bathroom dry faster. When the swing of the switching drum 4 is in the A position, the warm air in the bathroom is blown out in the A direction 8, and when the swing of the drum 4 is in the B position, the warm air in the bathroom is also B.
It will be blown out in the direction 9, and the blowing direction of the warm air will fluctuate. This fluctuation has the effect of promoting the drying of clothes dried in the bathroom.

Next, the heating mode will be described with reference to FIG. 2. At this time, the switching drum 4 fully closes the exhaust port of the outdoor unit, so the air from the fan 2 is heated by the heater 3 and the warm air flows into the bathroom. All blown out as 10.

Next, the ventilation mode will be described with reference to FIG.
The heater 3 is turned off, and the switching drum 4 completely closes the exhaust port inside the bathroom, so all the air in the bathroom is exhausted outdoors.
11 will be done.

The operation of the swing louver unit 7 will be described with reference to FIG. 4. When the swing louver 7 is not used, the temperature in the bathroom varies by 11 °, whereas when the swing louver 7 is used. It was proved by the experiment that the variation was reduced to 4deg and the temperature unevenness in the bathroom was reduced. At this time, the swing louver unit 7 swings 2.5 times a minute. When the swing louver unit 7 was not used, it took 162 minutes for the clothes dried in the bathroom to completely dry, but with the swing louver unit 7, it was 142 minutes, or 12.3%. It has become possible to save time.

[0010]

The effect of the present invention is to increase the drying effect in the bathroom by using the swing louver unit and the axially movable switching drum which is controlled and driven by one fan.
