Look at the background with the washer and dryer beneath the open window. In 99% of installations, the dryer would be vented through the wall beneath the window and if you had it open while using the dryer, depending on prevailing wind direction, the dryer exhaust would come back in through the window; not all of it, but certainly some of it. Also, these old style dryers with the belt-driven blowers had the exhaust vent just below the control panel so the dryer exhaust would be blowing out just below the window.
You will also notice that there is no lint screen access on top of the dryer because if you wanted a lint screen, it had to be mounted to the back of the dryer which would not allow flush to wall installation. So, this setting for the dryer would have hot, linty air blowing out right below the open window and, in the winter, condensing moisture trapping the lint on the wet glass. The disfunctionality makes me think of Frank Lloyd Wright, but probably many architects could share the blame for this attempt to get the wife out of the basement into a sunlight and fresh air-filled first floor laundry.
