Abstract: The invention concerns a method for varying and regulating the speed of a motor powered from a voltage source via a triac, comprising, at least once every alternating voltage interval, the following steps: computing a surface value (SI) corresponding to the current absorbed (I(M)) in a time window (FT) defined between a current switching-on time (ti) and a following current switching-off time (tf); computing an interval of the next triac-blocking time (t′); and controlling the starting of the triac when the blocking time (t′) has elapsed. The invention is useful in particular for household electric and house automation appliances operating at variable speed.

Abstract: An infusing apparatus comprises a collecting spout capable of being fixed under the outlet aperture of an infusing chamber. The spout has a lid provided with an opening through which the infusion penetrates, and an obstructer of the opening for in particular keeping the infusion at an optimal temperature. Elements for actuating the obstructer are further provided for automatically releasing the opening by the action of a stop integral with the apparatus, when the spout is being fixed on the outlet aperture. The actuating elements are also capable of being manually controlled for releasing the opening and allowing the infusion collected in the spout to be extracted through the opening. The invention is useful for household electrical coffee-pots or teapots.

Abstract: The invention concerns a household appliance comprising a housing (1) containing a motor (3) whereof the output shaft rotates an implement (13) housed in a bowl (8) whereon is fixed a lid (15) including a tab (23); and a safety device comprising a sliding vertical plunger (29) actuated by a control button (33) mounted movable on the housing between an off-position and an on-position, means (50, 52) for locking the button (33) in off-position when the lid is not fixed on the bowl, and for unlocking said button (33)when the lid is properly fixed on the such that the plunger (29) takes up a low position wherein it actuates a switch (27) to control the closure of the motor power supply, and retaining means (52, 54) co-operating with the lid tab (23) to prevent the latter from opening when the plunger (29) is in low position. The invention is characterized in that the safety device further comprises means (63) for maintaining the plunger (29) in low position when the switch (27) is locked in closed position.

Abstract: The invention concerns a brewing unit comprising a body (10) with a longitudinal axis (V) containing an infusion chamber (31) capable of receiving a pressing plunger (62) mounted mobile along the axis (V) by a drive mechanism (59), pumping member (40) for circulating water and brew, and a boiler (60) for heating the water for the preparation of the brew in the chamber (31). The invention is characterized in that the boiler (60) and the body (10) are formed in one single piece made of a heat conducting material with heating electrical resistance (26), water heating and passage channels (30) whereof the inlets (33) are connected to a cold water reservoir (R) and the ends (33′) emerge in the brewing chamber (31); and the pressing plunger (62) has a conduit (42) for the passage of the brew emerging through an outlet (42b), whereas the pumping member (40) is adapted to generate an ascending circulation of water in the brewing chamber (31) towards the conduit (42).

Abstract: A kitchen robot comprises a housing (2) containing a motor unit (4) whose output shaft (6) vertically projects from the housing and with an upper face (10) for receiving a first removable accessory (22) comprising a bowl (33) housing a rotating implement (36) integral with a vertical shaft (38) coaxially coupled with the motor shaft (6). The housing has a base (12) run through by a driving shaft (14) connected to the motor shaft (6) by a belt hoisting mechanism (16) designed for receiving a second removable accessory (24). The bowl (33) is mounted movable on a base plate (50) run through by the motor shaft (6) and which, before the bowl is fixed, is mounted flatly adjustable on the housing (2) so as to be coaxial with the motor shaft (6), and is fixed on the housing (2) after being adjusted.
