The invention relates to a hot air baffle plate. The hot air baffle plate comprises a plate body with an air inlet and an air outlet, wherein the air inlet is positioned in the middle of the plate body, and the hot air baffle plate further comprises a driving source, an air inlet sheltering plate, a first transmission mechanism, an air outlet sheltering plate and a second transmission mechanism. For the hot air baffle plate, through the movement of the air inlet sheltering plate relative to the air inlet, the magnitude of the air inlet amount of the air inlet is changed, through the movement of the air outlet sheltering plate relative to the air outlet, the magnitude of the air outlet amount of the air outlet is changed, further, the air amount entering a hot air chamber from a liner is adjustable, the air amount magnitude entering the liner from the hot air chamber and the air direction are adjustable, then the amount of the hot air and the air direction can be adjusted according to the different cooking modes and the different food materials, further, the temperature field in the liner is adjusted, and thus a better cooking effect is achieved. In addition, the movement of the airoutlet sheltering plate and the air inlet sheltering plate is linked through the first transmission mechanism and the second transmission mechanism, so that the air outlet sheltering plate and the air inlet sheltering plate can synchronously adjust the air inlet area of the air inlet and the air outlet area of the air outlet.
