A shoe care apparatus includes an inner cabinet, an inlet, an outlet, a connection passage, a heater, a blower, and a desiccant block. The air inside the inner cabinet flows into the connection passage through the inlet, and is discharged back into the inner cabinet through the outlet after being dehumidified by the desiccant block while circulating inside the shoe care apparatus. The heater is located in the inner space of the desiccant block to recycle the desiccant of the desiccant block.

The present example embodiments relate to food preparation devices using natural flowing and/or fan driven circulating air, and details for the construction thereof. Example embodiments are shown, which may be reduced in size and volume by the user. Example embodiments are shown which utilize natural convection airflow. Example embodiments are also shown which utilize fan driven air which flows in alternating directions.

A composite structure curing system employs a plurality of heaters mounted in at least one array in spaced proximity to a composite structure to be cured. A plurality of temperature sensors are mounted to sense temperature at selected locations on the structure. A control system receives an input from each of the plurality of temperature sensors and is adapted to control each of the plurality of heaters responsive to each input to establish a predetermined temperature profile on the structure during cure.

A plant dryer with improved convection flow is provided. The plant dryer has minimal corners in the drying vessel to promote efficient distribution of heated air through the device and to eliminate dead spots within the unit. The plant dryer has additional safety features where, unlike a conventional oven configuration, the unit may not be operated without the drying bowl properly placed within the unit.

A system and method for an intelligent hair drying/styling apparatus with user information transmission and storage capabilities is herein provided. The hair drying/styling apparatus houses a control circuit board and an infrared or temperature sensor (or camera) in order detect an individual's hair condition moisture level to determine a user specific, customizable dryer setting. The information detected by the sensor is stored locally, on a proximal Internet-enabled device, or on a remote or cloud-based server and accessed by the hair drying/styling apparatus through a wireless local area network connectivity function. Accordingly, a user's hair temperature-drying profile may be stored and later recalled to provide optimal hair styling setting customized for that user. This innovation will enable any number of hair professionals and or end consumers to improve styling and dry time. Such a profile may contain a proprietary V-Factor calculation that will, among other applications, correspond to the use of a coordinated and optimized hair spray solution. According to the present invention, energy usage is reduced to enable a more efficient design.
