We present a new model of large-scale multilayer convection in solar type stars. This model allows us to understand such self-similar structures observed at solar surface as granulation, supergranulation and giant cells. We study the slow-rotated hydrogen star without magnetic field with the spherically-symmetric convective zone. The photons flux comes to the convective zone from the central thermonuclear zone of the star. The interaction of these photons with the fully ionized hydrogen plasma with T> 105K is carried out by the Thompson scattering of photon flux on protons and electrons. Under these conditions plasma is optically thick relative to the Thompson scattering. We find the stationary solution of the convective zone structure. This solution describes the convective layers responsible to the formation of the structures on the stars surface.
