Abstract: The present invention relates to a cyclone separation device for separating particles from air and a cyclone vacuum cleaner (80). It has the objective to reduce noise without impairing the dirt separation performance. This is achieved an arrangement comprising a cyclone chamber (10), a dirt collecting chamber (50) arranged adjacent to the cyclone chamber (10) for collecting dirt particles separated from air, a dirt-duct (40) between the cyclone chamber (10) and the dirt collecting chamber (50) for allowing dirt particles to pass from the cyclone chamber (10) towards the dirt collecting chamber (50), and an air-guide (60) arranged adjacent to the dirt-duct (40) for reducing the momentum of the air in the dirt-duct (40).

Abstract: The present invention provides a beverage preparation machine comprising a detachable liquid container (10), a liquid level sensor (19) for determining the liquid level within the liquid container (10), and a riser pipe (16) connectable with the liquid container (10), wherein the liquid level sensor (19) senses the liquid level within the riser pipe (16) for determining the liquid level within the liquid container (10). This beverage preparation machine provides the advantage that the liquid level in the riser pipe is kept exactly the same as in the liquid container during consumption of liquid out of the liquid container and that the liquid level in the riser pipe is not influenced by a suction effect caused by this consumption. This gives the advantage of measuring exactly the amount of water removed out of the water container, which provides the opportunity to control the quantity of liquid, which is to be consumed, as accurate as possible.

Abstract: An apparatus for preparing beverages, with a filter carrier (5) or filter for retaining a substance to be brought into contact with water. The filter carrier or filter is provided with a filter inlet (51) and a filter outlet (52). At least a lower portion of the filter carrier (5) or the filter is arranged in a filter casing (8) so as to be free from the filter casing (8). The filter casing (8) is provided with a beverage passage (81) which is in communication with the filter outlet (52). A weighing structure (6) carries the filter carrier (5) or the filter and is adapted for providing an indication as to the weight of the filter carrier or the filter and of the substance retained therein. For storing the prepared beverage, a beverage receptacle (9) is provided which has a with an inlet opening (91) communicating with the filter outlet (52) and located downstream thereof when in the operating condition.

Abstract: A coffee maker with a water reservoir (4) provided with a filling opening (41) and a reservoir outlet (11); a heater-pump (12) for heating and supplying water with an inlet (14) which is connected to said reservoir outlet (11) and with an outlet (15); a filter holder (5) with a filter inlet (51) connected to said heater-pump (12) and a filter outlet (52), which filter holder has an upper portion (54) having a larger horizontal cross-sectional surface area than a lower portion (55) thereof; and at least in the operating condition, a coffee jug (9) under said filter holder (5), which coffee jug has an inflow opening for brewed coffee downstream of said filter outlet (52), wherein at least a portion of the water reservoir (4) is located next to the filter holder (5); the portion of the water reservoir (4) located next to said filter holder (5) at a level of said lower portion (55) of said filter holder extending to below said upper portion (54) of said filter holder.

Abstract: An apparatus for brewing hot beverages, such as coffee, comprising a water reservoir, a heating element for heating water in the water reservoir, an extraction device, an electric pump and a thermostat for the detection of the temperature of the water in the reservoir. The thermostat is connected in series with the heating element and the pump is connected in parallel with the thermostat. After the water has reached the desired temperature the thermostat is closed, which causes the pump to be switched on in order to pump the hot water to the extraction device. During the pumping phase the power of the heating element is virtually cut off.

Abstract: A coffee maker comprises a water reservoir, a water heating and supply device for supplying hot water to a filter device, the brewed coffee flowing from the filter device to a receptacle. The coffee maker includes a level detection circuit for detecting the water level in the reservoir, and this water level is used to control the brewing process so as to vary the flow of hot water to the filter device in dependence upon the water level in the reservoir. The water level may be used to control the power of a heating element in a continuous heater or may be used to control the operation of a pump in a pumped system.
