The invention is directed to a coffee maker for the preheating and keeping warm of cups, including a support surface (3) for cups (7, 8) and a heat source (2) delivering heat also to the cups (7, 8) resting on the support surface (3), wherein water held in a water reservoir (1) is heatable by means of the heat source (2) to a temperature such that vapors and/or steam are formed. Discharge orifices (9, 10) are provided in the support surface (3) for passage of the vapors and/or steam therethrough to circulate around the cups (7, 8) resting on the support surface (3), thereby heating them. In this manner, the cups are preheated readily and kept warm durably. In addition, the discharge orifices (9, 10) in the support surface may be closable by a spring-loaded flap structure (19) or a valve, a flap structure (19) or a valve being movable to an open position by the weight of a cup (7, 8).

The brewing device is composed of a housing part including a piston, vertically slidable in the housing part. On the housing part, a filter basket holder is mounted which is pivoted horizontally about the tilting axis and is provided with a filter basket to be filled with ground coffee. When the piston is lowered and reaches into the filter basket (i.e., its working position), the filter basket forms with it a pressure chamber, in which the ground coffee is enclosed, into which, on the piston side, hot water under pressure is urged through a conduit, and from which, on the filter basket holder side, the prepared espresso coffee beverage is discharged through at least one outlet opening. When the piston is lifted, the filter basket holder with the filter basket can be swung about a vertically extending tilting axis out of the range of effect of the piston. The tilting range of the filter basket holder reaches from its working position to its feed position, in which the filter basket is accessible from the outside. Only in its working position is the filter basket holder secured in respect of the housing part against movement in a vertical direction by supporting elements provided on both the filter basket holder and the housing part.

An espresso coffee making system includes an unpressurized boiler vessel with an electric heating element arranged outside the boiler vessel for heating water in the boiler vessel for delivery to a perforated filter holder of the espresso coffee maker. A tube is provided between the electric heating element and the boiler vessel that is in thermal contact with both the heating element and the boiler vessel. A valve allows water from the boiler vessel to be recirculated by a pump through the tube to generate steam, without overheating the water contained in the boiler vessel.

The invention is directed to a beverage brewing apparatus having a water reservoir (1) and a pump (6) powered by an electric motor (45), the pump pressurizing water from the water reservoir (1) and delivering it to a flow-through heater (11) heated by an electric heater (14). In the flow-through heater (11), water is heated in a water conduit (13) and subsequently fed to a pressure chamber (35), adapted to be filled with coffee grinds, of a brewing unit (34) from which, following an extraction operation, the brewed coffee flows into a receptacle (38, 39). According to the invention, a valve device (20) opening when a predetermined pressure is exceeded is provided in the fluid path (9, 13, 15) between the flow-through heater (11) and the brewing unit (34). As a result, the water current delivered by the pump (6) and flowing through the flow-through heater (11) is maintained nearly constant, causing a uniform transfer of heat in the flow-through heater (11) and avoiding a standstill condition of the electric motor (45). This also keeps the temperature control of both the flow-through heater (11) and the water heated in the flow-through heater (11) at an approximately constant level.
摘要:
A toothbrush including a brush head, bristle clusters protruding from a cleaning surface of the brush head and a depression disposed in the surface and surrounding at least one bristle cluster, the depression having a bottom into which the bristle cluster penetrates and in which the bristle cluster is fixed.
摘要:
The invention pertains to a toothbrush (1) with a brush head (2), from a surface (10) of which bristle clusters (11-17) protrude. According to the invention, at least one bristle cluster (11) is surrounded by an annular depression (21) in the surface (10). The invention improves the mobility of these bristles such that they are able to better penetrate into and clean the interdental spaces.
摘要:
A toothbrush having a head with a first end and a second end with peripheral edge regions extending between the first end and the second end is described. The head includes a first surface and a second surface opposite the first surface. The first surface includes raised portions and depressed portions, wherein the depressed portions are adjacent the peripheral edge regions. A first plurality of cleaning elements protrude from the first surface, and a second plurality of cleaning elements protrude from the first surface. Each of the first plurality of cleaning elements protrudes from a depressed portion and has a cross section. Each of the depressed portions has the same cross section as each of the first plurality of cleaning elements.
