Abstract
A kitchen machine provided with a housing (1) and an attachment (9) with a rotatable tool (17) which can be placed on the housing (1). The tool (17) can be driven by an electric motor (25) which is arranged in the housing (1) and fastened to a frame (39). The frame (39) is fastened to the housing (1) by means of elastically deformable suspension elements (65, 83), which suspension elements (65, 83) are each supported by a support member (69, 85) of the housing (1). The suspension elements (65, 83) have a mechanical stiffness which depends on a surface area of a contact face (73, 93) present between each suspension element (65, 83) and the relevant support member (69, 85). The said surface area and the mechanical stiffness increase with an increase in the mechanical load acting on the frame (39). Since the mechanical stiffness of the suspension element (65, 83) increases with an increase in the mechanical load acting on the frame (39), a good noise insulation of the electric motor (25) is achieved in the case of a low load on the frame (39), while a good protection of the frame (39) and the electric motor (25) against load fluctuations is achieved in the case of a high load.
