It's been a while since I worked on the US appliance market, but there are no smaller companies in the appliance space outside of some high European brands at the top end of the market.
I am not that well versed on the manufacturing side of the things, but I believe it is impossible for a smaller player to compete in the mass market due to extremely low margins (under ~5%), particularly in the "basic appliance" segment and the fact that manufacturing is extremely sensitive to scale (your per unit manufacturing cost will likely be significantly higher than Samsung, LG, Hair, Electrolux etc.).
Essentially, a smaller company will always have SKUs that will be more expensive than the comparable SKU from a major company while also being "offbrand" and having weaker distribution and ecosystem networks.
