The invention provides an appliance base and a household electrical appliance. The appliance base comprises a support, wherein rotary fixing mechanisms are connected to the support. Each rotary fixing mechanism comprises a connecting piece, a damping part, an angle adjustor and a rotating shaft, wherein the damping part is arranged on the connecting piece; the rotating shaft is in contact with the damping part, passes through the connecting piece and is connected with the support; the connecting piece can rotate around the rotating shaft relative to the support; the angle adjustor is arranged on the rotating shaft; the connecting piece is provided with a first limiting surface and a second limiting surface which are opposite to each other vertically; the first limiting surface is pressed against the angle adjustor for preventing the connecting piece from rotating downwards when the connecting piece is at a first position; the second limiting surface is pressed against the angle adjustor for preventing the connecting piece from rotating upwards when the connecting piece is at a second position. According to the appliance base, the depression angle and the elevation angle of the household electrical appliance can be adjusted according to settings.
