A heating device for use in warming the contents of spray bottles. The heating device includes a housing having at least one heating plate on the upper surface thereof. The heating plate includes an electrically operated heating element. The heating plate is controlled by the user via a dial that allows a user to select the temperature of the heating plate. The base of a spray bottle can be positioned directly on the surface of a heating plate so that heat from the heating plate is transferred to the spray bottle in order to warm the contents thereof. The spray bottle is preferably composed of a heat resistant material so that the spray bottle will not degrade or melt upon heating. The housing of the heating device may include one or more storage compartments therein for use in storing various items therein.

A bottle warming apparatus is disclosed that combines heating and agitating of a bottle and its contents in order to achieve even warming, as well as, mixing the contents of the bottle.

A method of arranging an induction coil in a food service well includes supporting, by supports in an extended position, the induction coil at a first height in the food service well, rotating the supports from the extended position to a retracted position, and supporting, with the supports in the retracted position, the induction coil at a second height in the food service well, the first height different than the second height.

A cooking utensil includes a body, the body having an infrared heating member; an infrared wave-transmitting separator, the infrared wave-transmitting separator includes a first side surface provided facing the infrared heating member and a second side surface provided facing away from the infrared heating member, and at least a part of the first side surface being not coplanar with another part of the first side surface.

Devices, systems, and apparatuses, and associated methods of preparing a liquid food item for consumption by a liquid food item preparation device are disclosed herein. In one embodiment, a device includes an inner shell having an inner surface and an outer surface, an outer shell having an inner surface and an outer surface, the inner surface of the inner shell defining a liquid holding volume and the outer surface of the inner shell and the inner surface of the outer shell defining a vacuum chamber. The outer shell and inner shell can be configured to form an orifice to the liquid holding volume at their junction. The device can be configured to prepare a liquid food item for consumption, including by powering a heating element and mixer device that can be configured to respectively heat and mix a liquid food item in the liquid holding volume.

A food delivery apparatus includes a domed shell that defines an interior space. A thermal storage device is secured to the shell so as to direct heat downward to food within the interior space.

A kitchen appliance is disclosed. The kitchen appliance comprises: a user interface control unit for interacting with a user; a plurality of driver units configured to control power supply to a plurality of coils; and the plurality of coils configured to heat one or more cookers based on electromagnetic induction effect, wherein each driver unit is configured to generate a control signal for a corresponding coil of the plurality of coils, and the control signal is used for controlling the power supply to the corresponding coil by controlling turn-on or turn-off of an insulated gate bipolar transistor (IGBT) in a single-pipe module.

An electric heater includes a substrate; and a plane heating element disposed on one surface of the substrate, in which the plane heating element includes a pattern portion including a start point and an end point; and an electrode portion connected to the start point and the end point of the pattern portion, and a thickness of the electrode portion is thicker than a thickness of the pattern portion.

A disposable support pan has a sidewall with a top lip that support the lips of rectangular food trays above a support surface. A disposable suspension tray inside the support pan has a flange resting on a support pan shoulder so the bottoms of two pockets in the suspension tray are between the support surface and the bottom of the food trays. Water in each pocket reacts with a calcium-oxide packet in each pocket to boils a predetermined amount of water to generate steam that heats the food trays without having the packets contact the food trays. One or two tray supports on each side of the pan may extend from the shoulder to a top support flange extending outward around a periphery of the support pan. The suspension tray has corresponding recesses to mate with the tray supports to keep steam from entering the area below the suspension tray.

Devices for prolonging the quality of a warm food item contained within the device, the devices include an enclosure, a convection heat source, a ventilation system, and a radiant heat source. The enclosure is configured to receive the warm food item. The convection heat source is mounted inside the enclosure and configured to direct heated air within the enclosure. The ventilation system is mounted to the enclosure and configured to move air through the enclosure. The radiant heat source is mounted inside the enclosure in a position to irradiate the warm food item received in the enclosure. In some examples, the devices include an enclosure, a convection heat source, and a radiant heat source with the convection heat source configured to direct heated air within the enclosure from a plurality of positions along a sidewall from a back to a front of the enclosure.
