Abstract
A grooming appliance generally includes a handle and a grooming head attached to the handle. The grooming head generates heat during operation of the appliance. The grooming appliance further includes a cooling system disposed at least in part within the handle. The cooling system has a thermoelectric cooling device for removing heat from the grooming head during operation of the appliance.
Claims20
A grooming appliance comprising:
- a handle;
- a grooming head detachably disposed on the handle, wherein the grooming head generates heat during operation of the appliance;
- a cooling system disposed at least in part within the handle, wherein the cooling system comprises a thermoelectric cooling device for removing heat from the grooming head during operation of the appliance;
- the grooming head having a plurality of spaced-apart thermally conductive terminals, and the handle having a plurality of corresponding thermally conductive terminals;
- and
- wherein when the grooming head is attached to the handle, the plurality of spaced-apart thermally conductive terminals engages with the plurality of corresponding thermally conductive terminals at an interface between the grooming head and the handle.

An electric hair grooming appliance comprising:
- a handle;
- a motor housed within the handle;
- a head detachably connected to the handle, wherein the head comprises a blade set and a blade cartridge configured to support the blade set on the handle, the blade set comprising a toothed stationary blade and a toothed movable blade arranged in sliding, face-to-face contact with the stationary blade, wherein the blade cartridge comprises:
- a blade frame to which the stationary blade is fastened;
- a drive member on which the movable blade is seated, wherein the drive member comprises a follower configured to drive the movable blade into oscillation when the appliance is operated;
- and
- a biasing assembly configured to bias the movable blade and the drive member toward the stationary blade, wherein the biasing assembly comprises a spring and a blade support seated on the spring for engaging the movable blade and guiding oscillation of the movable blade such that the movable blade, the drive member, and the biasing assembly are secured between the stationary blade and the blade frame;
- and
- a cooling system comprising a heat sink and a Peltier device situated in conductive heat transfer with the heat sink and with at least one of the motor and the blade set such that the Peltier device is configured to transfer heat from the at least one of the motor and the blade set to the heat sink during operation of the appliance;
- the head having a plurality of spaced-apart thermally conductive terminals, and the handle having a plurality of corresponding thermally conductive terminals;
- and
- wherein when the head is attached to the handle, the plurality of spaced-apart thermally conductive terminals engages with the plurality of corresponding thermally conductive terminals at an interface between the head and the handle.
