[0003]
A blower provided with a resistor 101 such as a heat exchanger downstream, having the same rotating shaft 102, two sirocco fans 104 driven by one motor 103, and a housing 105 containing the sirocco fan 104 Met.
[0004]
A conventional bathroom dryer will be described with reference to FIG.
[0005]
A heat exchanger 107 that is a heat source, a circulation fan motor 109 that drives a circulation fan 108 that circulates and blows warm air into the bathroom via the heat exchanger 107, and a ventilation fan 110 that ventilates air containing moisture in the bathroom A ventilation fan motor 111 for driving the motor, an electrical part 112 for controlling the operation, and a blowout louver 113 for controlling the blowout direction to the bathroom. The axial direction of both the circulation fan motor 109 and the ventilation fan motor 111 is set to the product mounting ceiling. Both are provided in a direction perpendicular to the surface, the circulation fan 108 sucks air in the bathroom, blows warm air through the heat exchanger, and the ventilation fan 110 sucks air in the bathroom and blows it out. Met.
[0006]
Moreover, it was the bathroom dryer in which the air path which guides a warm air to the blowing louver 113 which blows a warm air to a bathroom was installed.
[0007]
[Problems to be solved by the invention]
In such a conventional blower, the flow velocity is concentrated in the vicinity of the discharge port of the sirocco fan 104 with respect to the resistor 101 installed downstream, the pressure loss becomes large, and the performance such as heat exchange also deteriorates. In addition, there is a problem that the noise of the blower that can be heard from the opening 106 of the housing 105 is large. By causing the resistor to flow at a more uniform wind speed, pressure loss is reduced, and heat exchange and the like are performed. There is a demand for improving performance and further reducing noise.
