A vessel for frying, baking or cooking foodstuffs, includes at least one visible first material and one visible second material, wherein at least the first material reversibly changes color thermochromically when heated. The coloring of the two materials is selected in order for a color difference between the two materials to change visibly when the vessel is heated.

A cooking container includes a container unit and a temperature information processor disposed on the container unit. A bottom of the container unit is a heated region to carry a heat source, and a side wall of the container unit is provided at least with a temperature-sensing element channel which is extended to a location close to a center of the heated region. A temperature-sensing element which is connected with the temperature information processor is extended deeply into a location close to the center of heated region from the temperature-sensing element channel, allowing the temperature detected to be close to the actual heated temperature of the cooking container.

A stirring paddle for a cooking pot having a temperature sensor that preferably extends from the paddle handle to a paddle shaft and to the paddle blade. A display in the handle or grip or in the shaft displays temperature measured by the temperature sensor.

A handle for a cookware device contains a power supply that is operative to energize one or more of a processor, transceiver and accelerometer, as well as a memory device. The processor is also connected to a one or more external leads that extend into the handle at least to the connection to a sidewall of cooking device for further connection to a sensing circuit or power harvesting circuit. The end of the handle holds at least the processor but is in removable engagement from the portion with the power supply with a resilient sealing member to form a water proof seal.

Disclosed are exemplary embodiments of quick release detachable handles for culinary vessels. Also disclosed are exemplary embodiments of culinary vessels that include quick release detachable handles.

According to one example, a cookware apparatus includes a vessel. The vessel includes a bottom, and a sidewall surrounding the bottom and extending upward from the bottom so as to form a fluid retaining interior region. The sidewall terminates at a rim. The vessel also includes a channel extending through a portion of the bottom and further extending upward into and through a portion of the sidewall. The channel has an opening positioned in an external surface of the sidewall. The cookware apparatus further includes a thermal sensor positioned within the channel. The thermal sensor extends through the portion of the bottom and further extends upward into and through the portion of the sidewall.

The invention relates to a handle for a cooking vessel that includes at least one thermoelectric generator. The thermoelectric generator includes at least a first contact surface thermally connected to a heat sink and the heat sink is formed from a material that undergoes a phase transition when heated to temperatures varying between 50° C. and 70° C.

A placeable cooktop utensil includes: a handle for handling the placeable utensil; a controller; a transmitter unit for transmitting signals from the placeable utensil to the cooktop; and at least one input unit having at least one input area integrated in the handle for a user of the placeable utensil to input a user command, the transmitter unit and the at least one input unit being connected in signal communication with the controller, and the cooktop being controllable by the user command. The handle has a gripping portion for gripping and manually moving the placeable utensil and at least one input portion. The at least one input area is in the at least one input portion. At least one sensor for detecting the handle being approached and/or contacted by the user, is in the gripping portion.
