The utility model relates to kitchen small household electrical appliance technical field, concretely relates to a kind of compact air fryer of high-efficiency heating, including shell, upper pot body component, lower pot body component, heating mechanism, air deflector etc., upper pot body component and lower pot body component are arranged up and down in vertical direction, not traditional side by side, this makes equipment more compact in width direction, heating mechanism is centrally arranged in shell, the heating mechanism includes the heating
pipe generating heat and fan driving air circulation, air deflector is arranged in front of the air outlet of heating mechanism, is the
core component of high-efficiency heating, the air deflector is designed with the lower air deflector channel of downwardly inclined extension, the air outlet of lower air deflector channel is accurately aligned with the air inlet of pot body component, hot air is efficiently guided to upper pot cooking space, the utility model overcomes the problem that existing double-pot air fryer is designed more left and right, leading to equipment overall width is larger, occupies kitchen countertop space more, not enough compact.
