Electrical device for making beverages using power tool battery

An electrical device comprising:

• a housing;
• at least one battery-mount part disposed on the housing and configured such that at least one battery designed for use as a power supply of a power tool is mountable thereon;
• a heat-generating means for boiling water by using electric power supplied by the at least one battery mounted on the at least one battery-mount part, the heat-generating means being disposed within the housing;
• a drip case mountable in the housing and configured to hold a pod, which contains a predetermined amount of tea leaves or coffee grounds held in a water-permeable bag-shaped element;
• and
• a hot water supply configured to automatically supply water boiled by the heat-generating means to an interior portion of the drip case so that it is poured or otherwise dispersed onto the pod;
• wherein:
• the drip case further includes an extraction part configured to allow a hot beverage produced by the water that has been poured onto the pod to flow downwardly out of the drip case;
• the at least one battery-mount part comprises two of the battery-mount parts configured such that, when one battery is mounted on one of the battery-mount parts, another battery is prevented from being mounted on the other battery-mount part;
• the two battery-mount parts are provided on one side surface of the housing;
• a lid is provided on an upper surface of the housing and is configured to close and open an opening of a water reservoir within the housing;
• and
• the lid is located on an upper side of the one side surface of the housing on which the battery-mount parts are provided, and is configured such that the lid stands up like a wall along an end edge of the upper surface of the housing when the opening of the water reservoir is opened.

An electrical device comprising:

• a housing;
• a water reservoir configured to hold water within the housing;
• at least one battery designed for use as a power supply of a power tool;
• at least one battery-mount part disposed on the housing at a location lower than the water reservoir in a vertical direction of the electrical device, the at least one battery-mount part being configured such that the at least one battery is mountable on the at least one battery-mount part by sliding the at least one battery downward in the vertical direction and is detachable from the at least one battery-mount part by sliding the at least one battery upward in the vertical direction;
• a heat-generating means for boiling water by using electric power supplied by the at least one battery mounted on the at least one battery-mount part, the heat-generating means being disposed within the housing;
• a drip case mountable in the housing and configured to hold a pod, which contains a predetermined amount of tea leaves or coffee grounds held in a water-permeable bag-shaped element;
• and
• a hot water supply configured to automatically supply water boiled by the heat-generating means to an interior portion of the drip case so that it is poured or otherwise dispersed onto the pod;
• wherein the drip case further includes an extraction part configured to allow a hot beverage produced by the water that has been poured onto the pod to flow downwardly out of the drip case.

An electrical device comprising:

• a housing;
• a water reservoir configured to hold water within the housing;
• two battery-mount parts disposed on the housing at a location lower than the water reservoir in a vertical direction of the electrical device, the two battery-mount parts being configured such that batteries designed for use as a power supply of a power tool are respectively mountable thereon;
• a cover member movably coupled to the two battery-mount parts and configured to expose one of the two battery-mount parts while covering the other of the two battery-mount parts such that, when one battery is mounted on the exposed one of the two battery-mount parts, another battery is prevented from being mounted on the covered one of the two battery-mount parts;
• a cover-operation switch configured to be operated in conjunction with movement of the cover member;
• a heat-generating means for boiling water by using electric power supplied by the one battery mounted on exposed one of the two battery-mount parts, the heat-generating means being disposed within the housing;
• a drip case removably mounted in an interior of the housing, the drip case having a side wall and an extraction part defining an interior portion configured to contact and support both a pod, which contains tea leaves or coffee grounds held in a water-permeable bag-shaped element, and a mesh filter configured to hold loose coffee grounds or loose tea leaves;
• and
• a hot water supply configured to automatically supply water heated by the heat-generating means to the interior portion of the drip case so that the hot water is poured or otherwise dispersed onto the pod or onto loose coffee grounds or loose tea leaves contained in the mesh filter;
• wherein:
• the extraction part has one or more holes that allow a hot beverage produced by the hot water that was poured or otherwise dispersed into the interior portion of the drip case to flow downwardly out of the drip case;
• the interior portion of the drip case is designed to hold only one of the mesh filter or the pod at a time;
• and
• the cover-operation switch is configured to disconnect a power-supply line between the heat-generating means and a first power-supply terminal of the covered one of the battery-mount parts, and to connect a power-supply line between the heat-generating means and a second power-supply terminal of the exposed one of the battery-mount parts.
