There is provided a system for filtering liquid. The system comprises a liquid storage reservoir and a liquid inlet reservoir. The system further comprises a filter receiving portion configured to receive a filter, such that, in use, a filter is provided between said liquid inlet reservoir and said liquid storage reservoir and is, in use, configured to filter liquid passing from the liquid inlet reservoir to the liquid storage reservoir along a first liquid flow path. The system further comprises second liquid flow path from the liquid inlet reservoir to the liquid storage reservoir which by-passes said filter.

A pod for storing and dispensing a beverage preparation ingredient during a dispensing operation. The pod comprises a body defining a cavity for storing the beverage preparation ingredient, said body comprising a dispensing side and a closed side, and at least one side wall extending from the closed side to the dispensing side; and an actuation member contained within said cavity. The actuation member is configured to cause an opening to be formed between said cavity and a region outside the pod when actuated. The opening is formed around a perimeter of a dispensing surface of the pod at a junction formed between the at least one side wall and the dispensing surface, the dispensing surface being provided at the dispensing side of the body.

A water filter and infusion pitcher apparatus includes a pitcher housing, a water filter disposed within the pitcher housing, and an infusion apparatus disposed inside the pitcher housing and detachably connected to the water filter. The infusion apparatus constructed to contain and/or hold material such as, for example fruit, vegetables, tea, medicines, flavorings, vitamins, minerals, and/or other items to infuse, seep, and/or dissolve into a liquid within the pitcher housing.

A water tank for a domestic appliance, having a connection for a filter cartridge, wherein an annular tank sealing surface is provided on the tank base for the sealed connection of the filter cartridge and the tank sealing surface encloses a tank passage opening for the water to flow out of the filter cartridge through the wall of the tank base to the domestic appliance, wherein the tank sealing surface has a varying radius along its circumference in relation to a central axis, such that the tank sealing surface comprises radial indentations and/or radial protuberances, wherein the radial protuberances and/or radial indentations of the tank sealing surface have a round profile.

A water reservoir for a drinks machine has a housing having a base and a side wall forming a water chamber. An outlet structure is formed on the base with an inner wall upstanding from the base, wherein an inner volume of the inner wall leads to an outlet of the water reservoir. An outer wall structure extends around the inner wall and a space between the inner wall and the outer wall structure forms a connection interface for connecting a water treatment unit. A lowest region of the inner wall defines the lowest liquid level in the reservoir. When the liquid is at the lowest liquid level, the water surface extends uninterrupted between the outside of the inner wall and the inside of the side wall.

A filter cartridge for the use in the interior of a water tank of a domestic appliance having a filter housing of which the wall separates in a watertight manner a housing internal side from a housing external side, wherein a filter inlet opening which in the operating position of the filter cartridge is disposed on the lower end region of the latter and is open in relation to the external environment of the filter housing is provided, wherein provided downstream of the filter inlet opening in terms of the flow direction of water during operation, in the interior of the filter housing, is a device for water conduction which comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet line for suctioning water from the filter cartridge.

An electrically operated beverage maker, in particular electrically operated coffee machine, having at least one component which is subjected to wear and tear and hence maintenance-relevant, wherein at least one load parameter which characterises an actual wear and tear of the maintenance-relevant component can be determined, and in that at least one reliability parameter of the maintenance-relevant component can be calculated, taking into account the specific load parameter(s) of the maintenance-relevant component.

A beverage preparation device comprising a main body, a tank, an assembly for pumping a liquid from the tank, and a unit for preparing the beverage, in which device an outlet path is defined inside the main body, the outlet path comprising a dispensing outlet, via which the beverage is dispensed out of the main body, and also comprising a filtering element that is detachably connected to the main body, wherein the filtering element is arranged downstream of the dispensing outlet relative to the outlet path.

In one aspect, a multifunctional drink making apparatus may include a main body that includes a water storage tank, a cold water pump and a hot water pump which are connected with the water storage tank respectively. A plurality of water filters can be connected from the water storage tank to improve the water quality. The drink making apparatus also includes an intelligent control display to intelligently control the hot water output to brew coffee, tea or the like according to the preference of the user. More importantly, the intelligent control display screen is connected with a wireless module, so the user can use an external electronic device to control the drink making apparatus through the intelligent control display to achieve the goal of internet of things, and increase the convenience and practicability of the drink making apparatus.

A filter cartridge for use in the interior of a water tank of a household appliance, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of a filter housing. A device for water conduction comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge in the interior of the filter housing, downstream of the filter inlet opening relative to the flow direction of the water during operation. A filter port has an annular filter sealing face for the connection of the filter cartridge in a water tank. The filter sealing face has a separately disposed filter-proximal guide structure for receiving a centering element for centering the filter cartridge.
