A method for calculating the humidity level in a cooking apparatus is disclosed. The method includes heating a food load in a cooking cavity of the cooking apparatus and selectively activating a convection fan in the cooking cavity. The method further includes monitoring a humidity signal detected by a humidity sensing apparatus in response to the activation of the convection fan. As a result of the activation of the convection fan, the method may determine an actual humidity level from a plurality of humidity levels based on a change in the humidity signal.

A heating apparatus including a storage device and at least one heater member. The heater member can be connected to the storage device and an electric power supply source. An inverter is connected to the output of the storage device and the electrical supply source. First switching elements are used to vary the first connection elements between an open circuit configuration and a closed circuit configuration in which electrical energy stored in the storage device is injected into the electrical supply source via the inverter.

A knob structure for an electromagnetic oven includes a knob switch assembly. The knob switch assembly consists of a sleeve button, a rotary encoder, a bracket of a display screen, and a control assembly. The knob switch assembly is connected to a printed circuit board through a through hole. A guide rib is disposed around a circumference of the through hole. The display screen with a protection assembly disposed outside is integrated with the knob switch assembly. The guide rib effectively prevents water from entering inside of the electromagnetic oven, lengthens a service life of the electromagnetic oven, and facilitates cleaning. The knob switch assembly integrated with the display screen realizes miniaturization and reduces a cost. The protection assembly ensures a display effect of the display screen.

The objective of the present invention is to provide a body contact-type warmer using a heat pipe, the warmer comprising: a heating part, which includes a body having a heat preserving material-filled space, and heat transfer protrusions formed at both sides of the body; a heat pipe embedded in the heating part and having a heater; caps for holding the heat pipe and blocking both ends of the heating part; a pair of heating plate fixing parts having heat transfer protrusions which come in close contact with the heat transfer protrusions of the heating part so as to transfer heat and, simultaneously, are used as connection means; and a heating plate put on the upper ends of the heating part and the heating plate fixing parts. The present invention can provide the body contact-type warmer having effects of: reducing energy and costs by using only one heat pipe; and being easily manufactured and having a simple structure since the heating part is aligned at the center thereof so as to enable heat of the heat pipe to be quickly and continuously transferred, and the heating plate fixing parts capable of heat transfer to the heating part and, simultaneously, being capable of fixing the heating plate are connected to both sides of the heating part so as to enable the heating plate to be heated, and thus the present invention is very useful.

The present invention relates to a process of making power-saving electric stoves, particularly having a large size and outer shapes similar to the conformations of traditional Tyrolean heaters or stoves, while having a very light weight and being easily movable to multiple locations of a house. The main characteristic of the present invention is that it includes making a hollow stove body, particularly having a large size, from expanded polystyrene or a similar thermoplastic polymer, with the application of an electric resistor, particularly a constant-power, and hence low-power consuming heating cable arranged around its outer surface in one or more coil loops with the interposition of a layer of adhesive material with at least one thread formed therein for supporting the resistor, with contiguous insulating grooves, and with later application of a final coating layer, made e.g. of tire-resistant cement mortar, whose outer surface may be provided with decorative designs or finishes and ornaments made of wood or other materials, which designs and ornaments may be similar to those formed on the outer surfaces of traditional Tyrolean stoves, whereas the basement of the hollow body is preferably supported by a smooth metal plate, allowing displacement thereof to any location of the house, proximate to a power outlet.

An electromagnetic oven includes a bottom case (1), a panel (2) and a thermostat (3). The thermostat (3) includes an inner bracket (31), a top end of the inner bracket (31) is provided with a temperature sensing cover (32) that contacts a cooking pot, and an inner cavity of the inner bracket (31) is provided with a temperature measuring element (33) for measuring a temperature of the temperature sensing cover (32) in a contact or non-contact manner. The thermostat (3) protrudes from a through hole of the panel (2) in a telescopic manner, and the temperature sensing cover (32) of the thermostat (3) contacts the cooking pot. A sealing structure for preventing soup from entering or a drainage structure for guiding the soup out of the bottom case (1) is disposed between the through hole of the panel (2) and the thermostat (3). In the present invention, the through hole is formed at the panel (2), and the telescopic thermostat (3) is disposed in the through hole, so that a close contact between the thermostat (3) and a bottom of the cooking pot may be realized, and an accurate measurement of a temperature of the bottom of the cooking pot by the thermostat (3) is ensured. The sealing structure or the drainage structure at the through hole of the panel prevents the soup on the panel (2) from entering an electrical component in the bottom case (1).

An oven in which a cooking space in a cooking chamber is dividable into a plurality of individual cooking spaces by a partition member. The oven includes a door assembly including a main door rotatably combined with a main body and provided with a plurality of openings corresponding to the respective plurality of individual cooking spaces and a plurality of individual doors rotatably combined with the main body to open and close the respective plurality of openings. The door assembly may selectively open and close the entirety of the cooking space or the respective plurality of individual cooking spaces, and thus a heat loss or danger of burn generated due to opening and closing the main door when only the individual cooking space is used may be prevented.

The present disclosure relates to a cooking device which allows a user to set a heating power level and a cooking time quickly and easily. A cooking device according to the present disclosure includes a new form of control device configured to control cooking processes using the cooking device.
