In fairness, my modern Danish apartment has a different voltage and power outlet in the place for the tumble dryer: 400V and probably one of these [1] though I've never pulled the machines out to look. In practise, the massively power-hungry dryers of decades ago aren't very common, so my dryer is connected to a normal 220V outlet. (Three-phase power in an apartment is now only used for the oven and hob, but is used in the building for the lift and the EV charging points in the basement.)
