Abstract: An electric cooking apparatus comprises a base (1) in the form of a frame defining a hollow internal region (6), a vessel (2) adapted to rest on the base in that internal region, an electric heating resistance (3) disposed above the vessel, a cooking grill (4) disposed above the resistance (3) and adapted to receive food to be grilled, and a thermal regulator (10) mounted in series with the electric heating resistance (3) and operating in a predetermined switching temperature range. A thermostatic safety switch (11) is disposed in the base and mounted in series with the heating resistance (3) and operates at a fixed switching temperature below the minimum temperature of that range and permits detecting, by thermal conduction, abnormal increases of the temperature of the vessel (2) and cuts off as needed the electrical supply of the electric heating resistance (3).

Abstract: A toaster comprises a housing (1) enclosing a carriage (4) movable between an ejection position and a toasting position to which it can be brought by a handle (6) connected to one end (7) of the carriage (4) by a driver (8) secured to a finger (11) adapted to actuate a control switch (12) for the electrical supply of a heater (3). The driver (8) is movably mounted on the end (7) of the carriage (4) for movement along a vertical path (l) so as to permit the finger (11) to free the switch (12) when the carriage remains blocked in its toasting position after unlocking a retaining device (10).

According to the invention, the supply circuit comprises a single high frequency alternating supply source (V) and an adapting means (Q) connected to the alternating supply source (V) and to two electrodes (11 and 12) energizing the piezoelectric element (3) and generating both voltages (V.sub.1 ') and (V.sub.2 '). The invention is for use in piezoelectric motors.

Abstract: An apparatus comprising a drive motor (7) with a shaft (8) having a front end for engaging a coupling device (20) for a whisk (10), and a rear end for engaging a drive (28) housed in a cylindrical body (31) and engageable by a mixing arm, as well as a vertically movable ejector member (51) linked to the coupling device. A movable mechanical assembly (70) is provided for releasing the ejector member (51) while blocking the internal space (74) in the body (31) so that only the whisk can be fitted, or alternatively locking the ejector member (51) in the down position while unblocking the internal space (74) in the body so that only the mixing arm can be fitted.

Abstract: An infusion machine including a cold-water container (1) which incorporates a water purification device (5) and which comprises a water outlet (2) connected to a water heater (3). The water purification device includes a removable cartridge (7) comprising a bottom part forming a cup (8) which is designed to be mounted sealingly in a suitable basin (10) formed in the bottom of the container, and in which is housed so as to be removable a filter sachet (15) containing a water purification substance (16), and a top part forming a cap (18) which is located in line with the cup (8) and which is able to close the latter, the cap (18) of the cartridge comprising at least one opening (42) through which the water from the container enters, and the cup (8) of the cartridge comprising at least one opening (51) through which the water flows into the water heater (3) after passing through the filter sachet (15) used particularly for electric coffee makers.

Abstract: A support for an electric kitchen beater comprises a plate (26) that supports the beater and a drive device (28) for a bowl (18). A drive transmission (30) is disposed in the plate and has a movement outlet connection (34) comprising a drive wheel (36) with a vertical axle (37) that is adapted to come into engagement with the edge (38) of the bowl (18). The plate (26) also carries, facing the drive wheel (36) a guide (39) adapted to maintain the edge (38) of the bowl against the drive wheel (36). The drive wheel (36) has an active friction surface (36'), and the guide comprises at least one friction roller (40) mounted rotatably about an axle (41) substantially parallel to the axle (37) of the drive wheel.

Abstract: A ripple current generator for an induction heating apparatus includes a resonant circuit with a current injecting self-inducting coil (6), a capacitor (13), an induction heating coil (14) and a high-frequency controlled power switch (12). The current injecting self-inducting coil (6) is saturable and mounted in series with a parallel assembly consisting of two arms; a first arm (B.sub.1) containing the switch (12) and a second arm (B.sub.2) containing a capacitor (13) mounted in series with the induction heating coil (14). The self-inducting coil includes a magnetic circuit that automatically reaches saturation during the resonance phase of the oscillating circuit. The generator is useful in household cooking appliances such as induction plates, cookers or deep fryers, as well as industrial induction heating equipment for treating metal components.

Abstract: A domestic deep fat fryer comprising, in a housing (1), a vessel (2) adapted to contain a cooking bath (3). An electric heating resistance (4) heats the cooking bath. A thermal regulator (6) of high thermal inertia is mounted in series with the heating resistance and operates over a predetermined range of switching temperature. The fryer moreover comprises a thermostatic safety switch (8) mounted in series with the electric heating resistance and operating at a fixed switching temperature higher than the maximum temperature of the temperature range of the thermal regulator (6). This thermostatic safety switch has a thermal inertia less than that of the regulator (6) so as to detect abnormally rapid temperature increases and to cut off the electrical supply in such case to the electric heating resistance.

Abstract: A hand-held electric beater-mixer comprises a drive motor (7), two coupling devices (20, 28) linked to the motor and engageable by a whisk and a mixing accessory (38) respectively, an electrical switch (71) operated by a button (67) having an "off" position, a number of "continuous on" positions and a "selective on" position, a vertical movable ejector (51), and a mechanical assembly (72) for preventing continuous operation when the mixing accessory is in place. The mechanical assembly comprises a movable member (74) which releases the ejector when the whisk is in place. The ejector has an engagement tab (53) enabling operation of the button when the ejector is in the raised position, and locks the ejector (51) in the lowered position when the mixing accessory is in place. The engagement tab (53) of the ejector locked in the lowered position locks the button (67) on the side corresponding to its "continuous on" positions.
