The housing (10) includes: a side enclosing plate (11) enclosing and defining an installation space, which is penetrating in an up-down direction for installation with a burner unit (20) of the burner (100); and an air distribution plate (12) disposed at and sealing a lower end opening of the installation space and located above the burner unit (20). A first air inlet (1021) and a second air inlet (1022), for air inflow, are defined in the air distribution plate (12) and spaced apart from each other. The first air inlet (1021) is in communication with an internal gas channel (202) in the burner unit (20), and the second air inlet (1022) is in communication with an external air channel (203) located at a side portion of the burner unit (20).
