AI Technical Summary

Benefits of technology

The patent describes a device that filters liquid as it flows through a storage reservoir. This prevents spillage, even if the water flow rate is too high for the filter to handle. The device also includes a heat exchanger that helps transfer heat away from the Peltier element, which generates cold.

Problems solved by technology

The water filtration step may provide a rate limiting step such that the rate at which water can be dispensed is limited by the rate of filtration, rather than by the mains supply.
It will be appreciated, however, that the speed at which water is filtered can provide a limiting step in such an arrangement such that it takes some time to fill a jug with filtered water.
Moreover, once the jug is depleted it takes time to re-fill the jug.
However, it would be understood that such an arrangement requires the delivery of large volumes of water in pre-sealed containers, rather than relying on the local supply of mains drinking water.
Chilling systems for known beverage dispensing systems may occupy large volumes of space, and may consume significant amounts of energy.

Embodiment Construction

[0087]In more detail, FIG. 1 shows a beverage preparation apparatus 100 comprising a water storage reservoir assembly 102, a dispensing assembly 104, and a mixing chamber 106. As discussed in more detail below, the reservoir assembly 102 is connected to the dispensing assembly 104 so as to provide a water supply. In use, a vessel 110 (e.g. a cup or bottle) is provided to receive a dispensed beverage below the mixing chamber 106. A pod 120 containing a beverage preparation ingredient is provided within the dispensing assembly 104. In use, water is dispensed into the mixing chamber so as to mix with the beverage preparation ingredient before being mixed and dispensed into the vessel 110. The beverage preparation apparatus 100 may, for example, comprise a countertop beverage dispenser, or other equivalently small and / or portable unit.

[0088]Referring now to FIG. 2, the reservoir assembly 102 comprises a main reservoir 112, an inlet portion 114, the inlet portion comprising an inlet rese...

Abstract

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.

Description

CROSS-REFERENCE TO RELATED APPLICATION DATA[0001]This present application claims priority to GB Patent Application No. 1817951.5, filed Nov. 2, 2018; and U.S. Provisional Patent Application No. 62 / 622,225, filed Jan. 26, 2018, the contents of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates to a system for filtering liquid. More particularly, but not exclusively, the present invention relates to a system for filtering liquid for use in a beverage preparation system, such as a chilled beverage preparation system.SUMMARY OF THE INVENTION[0003]It has long been known to provide filtration for water used in beverage preparation systems, so as to ensure an optimal quality of water is provided to a user. For example, many water dispensing devices which are connected to a mains supply of water are provided with an inline filter so as to ensure that all water that is dispensed has been filtered. The water filtration step m...
