Abstract
An electrical device includes a battery-mount part (40) configured such that a battery used as a power supply of a power tool is mountable thereon, and a heat-generating element (54) for boiling water using electric power from the battery (B1, B2) mounted on the battery-mount part. The electrical device further includes a drip case (21) for holding a pod, in which a predetermined amount of tea leaves or coffee grounds is encased in a permeable bag-shaped element. A hot water supply (50y) supplies the water boiled by the heat-generating element (54) automatically to the drip case (21). An extraction part (21p) in the drip case (21) allows a beverage produced by the hot water that has been poured onto (injected into) the pod to downwardly flow.
Claims20
An electrical device comprising:
- a housing;
- a plurality of battery-mount parts provided externally on the housing and configured such that batteries designed for use as a power supply of a power tool are respectively mountable thereon;
- and
- a heat-generating means for boiling water by using electric power supplied by one of the batteries mounted on one of the battery-mount parts, the heat-generating means being disposed within the housing;
- wherein the plurality of battery-mount parts is configured such that, when the one of the batteries is mounted on the one of the plurality of battery-mount parts, another one of the batteries, when placed adjacent to the mounted one of the batteries, is physically blocked by a cover member slidably mounted on the plurality of battery-mount parts or by the mounted one of the batteries from moving in a mounting direction with respect to the one of the plurality of battery-mount parts having the one of the batteries mounted thereon.
An electrical device comprising:
- a housing having a water reservoir defined therein;
- a plurality of battery-mount parts provided externally on a planar side surface of the housing and configured such that batteries designed for use as a power supply of a power tool are respectively mountable thereon;
- a heat-generating means for boiling water by using electric power supplied by at least one of the batteries mounted on at least one of the battery-mount parts;
- and
- a lid provided on an upper surface of the housing that adjoins the planar side surface and is at least substantially perpendicular to the planar side surface;
- wherein the lid is configured to close and open an opening of the water reservoir such that the lid stands up like a wall along an upper end edge of the planar side surface of the housing when the opening of the water reservoir is opened;
- and
- the plurality of battery-mount parts is disposed below the lid on the planar side surface of the housing.
An electrical device comprising:
- a housing;
- a first battery-mount part externally disposed on the housing and configured such that a first battery designed for use as a power supply of a power tool is mountable thereon;
- a second battery-mount part externally disposed on the housing and configured such that a second battery designed for use as a power supply of the power tool is mountable thereon;
- a heat-generating means for boiling water by using electric power supplied by the first battery mounted on the first battery-mount part or the second battery mounted on the second battery-mount part, the heat-generating means being disposed within the housing;
- a first power-supply line electrically connecting first power-supply terminals of the first battery-mount part and the heat-generating means;
- a second power-supply line electrically connecting second power-supply terminals of the second battery-mount part and the heat-generating means;
- a cover member movably coupled to the first battery-mount part and the second battery-mount part and configured to cover one of the first battery-mount part and the second battery-mount part while exposing the other of the first battery-mount part and second battery-mount part;
- and
- a cover-operation switch configured to detect movement of the cover member,
- wherein the cover-operation switch is configured such that removal of the cover member from the first battery-mount part and the second battery-mount part causes the first and second power-supply lines to be disconnected from the heat-generating means.
