Abstract
An electrical apparatus useful to prepare a hot beverage from a flavor substance. The apparatus has a flow-through heater, a container for a liquid and a cup unit for the flavor substance. A pipe joins the cup unit and the liquid container. The cup unit includes a cup and there is a filter carrier to fit in the top of the cup and to carry a filter containing the flavor substance. A passage extends through the filter carrier and is open at both ends of the carrier. A channel is formed between the base of the filter carrier and the passage. Further passages join the interior of the passage to the channel. The filter carrier has upper and lower closures. The heater unit has a container for a liquid; a heater for the liquid and a head to fit over the cup unit. The pipe extends from the heater to the head. The apparatus allows the liquid to pass from the container through the pipe through the head, into the filter and through the upper closure of the cup unit so that liquid may pass through the flavor substance in the filter to form the beverage.
