A pad device includes a pad unit for placement at least in part between a setting-down counter and a heated cooking vessel in a heating operating mode. To provide great flexibility, the pad device includes an electronic unit which supplies at least one function in at least one operating mode.

An ultra-thin heating device includes an upper heating pad, a lower heating pad, at least one electric heating piece and a power supply. The electric heating piece is installed at a preset position between the upper heating pad and the lower heating pad. The electrothermal sheet is electrically connected with the power supply. The upper heating pad and the lower heating pad are made of soft material. When a food needs to be heated, the food is placed on the preset position of the upper heating pad corresponding to the at least one electrothermal sheet, and the power supply provides electric power to the at least one electrothermal sheet to heat the food. Because the upper heating pad and the lower heating pad are made of soft material, when not in use, the ultra-thin heating device can be folded or rolled up for storage.

The present disclosure provides a heating cooker with improved usability. A heating cooker comprising: a heating unit that heats a cooking object; a temperature detector that detects temperature information about the cooking object; a controller that controls the heating unit based on heating conditions including at least a heating temperature and a heating time, and the temperature information; and a communicator that communicates with an external device, wherein the external device receives input information from a user, wherein the communicator transmits the input information received from the external device to the controller, and wherein the controller creates, when the input information is predetermined input information, update information about at least the heating temperature among the heating conditions based on the predetermined input information.

A cooking vessel sensor and an induction heating device including a cooking vessel sensor is provided. The cooking vessel sensor may include a cylindrical hollow body having a first receiving space defined therein; a hollow cylindrical magnetic core received in the first space and having a second receiving space defined therein; and a sensing coil wound on an outer face of the side wall by a predetermined number of winding counts. The cylindrical hollow body may have a side wall having a coil outlet defined therein, and the sensing coil may pass though the coil outlet out of the body. The cooking vessel sensor may further include a controller that applies a current to the sensing coil and determines, based on a sensing result of the cooking vessel sensor, whether the cooking vessel is inductive or has an inductive heating property.

An electric resistance heating coil assembly, as provided herein, may include a spiral would sheathed heating element, a thermostat, and a shroud cover. The spiral wound sheathed heating element may have a first coil section and a second coil section. The thermostat may be connected in series between the first and second coil sections of the spiral wound sheathed heating element. The thermostat may include a base and a top cap. The base may extend axially between a first end and a second end. The top cap may be held on the base at the first end. The shroud cover may be mounted to the thermostat below the top cap.

The present disclosure relates to a pizza warming serve tray device for increasing the length of time a pizza stays at an optimal temperature for consumption. In an exemplary embodiment, the device of the present invention comprises a pan and an induction base heating unit, wherein the material of the pan is a bonded metal alloy, and wherein the pan is coated with a molded, food-grade silicone to insulate the heat contained within the pan. The device of the present invention drastically increases the total length of time a pizza remains in the optimal temperature range.

A substrate processing apparatus includes a heater resistor; a digital filter configured to filter at least one of a detection voltage, which is a digital voltage value detected as a voltage applied to the heater resistor, or a detection current, which is detected as a voltage calculated from the heater resistor and a current flowing in the heater resistor and converted into a digital voltage value; and a controller configured to control a temperature of the heater resistor with the detection voltage and the detection current, at least one of the detection voltage or the detection current being filtered by the digital filter.

An electric resistance heating coil assembly, as provided herein, may include a spiral would sheathed heating element, a thermostat, and a shroud cover. The spiral wound sheathed heating element may have a first coil section and a second coil section. The thermostat may be connected in series between the first and second coil sections of the spiral wound sheathed heating element. The thermostat may include a base and a top cap. The base may extend axially between a first end and a second end. The top cap may be held on the base at the first end. The shroud cover may be mounted to the thermostat below the top cap.

The application relates to food preparation apparatus with an electrical heating device comprising at least two electrical PTC thermistors for heating a food in a food preparation space, wherein the electrical PTC thermistors are electrically connected in parallel. The parallel-connected PTC thermistors are electrically connected to each other by one or more electrical bridges.

Using designs in accordance with the present application, local heating during the preparation of a food may be avoided.

There is provided a cooker having at least one heating element (200). The cooker also has a supporting structure for supporting a cooking vessel above the heating element (200) and a bi-metallic element (202). The bi-metallic element (202) drives the heating element (200) to move based on a temperature of the bi-metallic element (202).
