  • Patent number: 9310110
    Abstract: A thermoelectric drinking apparatus has a feeding pipe, a cooling-gain circulating loop, a heating-gain circulating loop, an outlet pipe, and a thermoelectric heat pump. The thermoelectric heat pump has a cooling unit attached to the cold side of a thermoelectric chip, which has a cooling channel in its interior, and a heating unit attached to the hot side of the thermoelectric chip and provided with a heating channel in its interior. The feeding pipe conducts fluid into the cooling channel and the heating channel respectively. The cooling-gain and heating-gain circulating loop respectively cause fluids in the cooling channel and heating channel to create circular flows, such that the cold side and hot side of the thermoelectric chip respectively cool and heat the fluids via the cooling channel and heating channel. The outlet pipe discharges the cooled and/or heated fluids respectively from the cooling-gain circulating loop and heating-gain circulating loop.

  • Patent number: 9200823
    Abstract: An ice maker has a mold with a first piece and a second piece. A cavity within the mold includes a first reservoir in the first piece and a second reservoir in the second piece that align to substantially enclose the cavity. A fluid intake aperture in the first piece extends to the cavity for injecting water therein. A thermoelectric device has a cold side thermally coupled to the exterior surface of the second piece. The thermoelectric device transfers heat from the cold side to a hot side to provide a first temperature to the mold. A removable cooling source is thermally coupled to the hot side of the thermoelectric device. The cooling source is configured to reduce the temperature of the hot side to allow the cold side to provide a second temperature that is cooler than the first temperature to freeze the water in the cavity.
