    • The invention concerns a kitchen appliance comprising an electric drive motor (9) which is disposed in a housing (1, 3, 4) substantially perpendicular to the surface on which said appliance stands. The drive motor (9) is surrounded by a housing part (3), ventilation apertures (13, 14) being formed in the housing (1, 3, 4). The drive motor (9) is not provided with fan wheels. Viewed in the longitudinal extension (X) of the drive motor (9), the ventilation apertures (13, 14) are disposed substantially in the region of the opposite ends of the housing part (3). The ventilation aperture (14) through which the hot air (18) is discharged is disposed above the drive motor (9). As a result, even without fan wheels, an air flow is produced by convection from the air inlet apertures (13) to the air outlet apertures (14), so rendering the appliance more economical and quieter yet providing adequate cooling of the drive motor (9).

    • The description relates to an electric tooth-cleaning device (1) in which a cleaning instrument (19) is coupled to a drive sleeve (11) and can be rotated about a longitudinal axis (4). According to the invention, the coupling is made using an elastic component, especially a spring (21), having a slipping clutch (27) and/or a buffer region (28). The slipping clutch (27) normally forms a firm rotary connection between the drive sleeve (11) and the cleaning instrument (19). If, however, the cleaning tool jams between two teeth, for instance, the slipping clutch (17) slips and prevents possible damage. The buffer region (28) ensures that the cleaning instrument (19) is not moved, although this is intended by the user, if it is placed, for example, on the surface of a tooth and not in an interdental space.
