A variable temperature blender is disclosed for the cooking and preparation of heated sauces, jams, soups, purees, alternative milks, smoothies and more. A variable temperature blender has a lid assembly, a vessel assembly, and a base assembly. The vessel assembly has a blending vessel and a collar attached to a bottom portion of the blending vessel. The base assembly have a user interface, a motor, and a controller. A heating element positioned within the collar of the vessel assembly received an electronic signal from the controller via an electrical interface connecting the base assembly with the vessel assembly. The electronic signal activates or deactivates the heating element based on an operational mode of the variable temperature blender to heat a food item contained within the blending vessel.

An electric kettle may include a body formed by an outer body and an inner body having a cylindrical shape and an open upper surface and an open lower surface, a heat insulation space being formed between the outer body and the inner body, a lid configured to open or close the open upper surface of the body, a heating module configured to partition an inside of the inner body vertically and heat fluid, such as water inside of the inner body, a mounting portion which is formed on an inner surface of the inner body and on which the heating module is mounted, and a base on which a lower surface of the body is seated and which transfers power applied from outside to the heating module when the body is seated. The heating module may include a heating plate inserted through the open lower surface of the inner body and coupled to the mounting portion to form a bottom surface of the inner body, and a heater provided on a lower surface of the heating plate to generate heat.

A frozen food heating apparatus is disclosed, which includes a boiler body, a water tank in communication with the boiler body, and a container for containing food, a spray nozzle in communication with both the boiler body and the water tank being provided above the container, where a first solenoid valve or an electric ball valve is provided on a connection pipeline between the water tank and the spray nozzle, the spray nozzle is in communication with an upper end of the boiler body and a second solenoid valve is provided on a connection pipeline, and the water tank is in communication with the lower end of the boiler body and a third solenoid valve is provided on a connection pipeline.

Proposed is an electric kettle in which a main body is provided with a water level window. The electric kettle of the present disclosure includes the main body configured to receive water or food therein and provided with the water level window through which the level of water contained inside the main body is seen, a lid provided on an open upper side of the main body so as to cover the open upper side of the main body, and a base provided at a lower side of the main body so as to support the main body, wherein a flow path in which a fluid flows is formed in the water level window and has a bottom surface formed to be inclined. According to such a configuration, a fluid remaining inside the water level window decreases.

A roasting and glazing apparatus includes a roaster, an agitator mounted within the roaster bowl for mixing a mixture of nuts and sugar during a roasting or glazing operation, a heater controlled to heat the roaster bowl during the roasting or glazing operation, and a cover removably mounted to the roaster bowl. The cover includes a reservoir for receiving water from a user and restricting water flow from the reservoir into the mixture of nuts and sugar in the roaster bowl. The cover and the roaster bowl together define a vent on a side of the cover opposite the reservoir. The vent is configured to direct steam out of the roaster bowl in a direction away from the reservoir.

An electric kettle may include: a body receiving water or food therein; a lid configured to shield an open upper side of the body; a base provided at a lower side of the body and configured to support the body; a heating module provided in a side of the body and configured to apply heat to the body such that the content contained in the body is heated; and a handle provided at a side of the body and configured to be held by hand, wherein a control means is provided in the handle, the control means being configured to control power supplied to the heating module or to control a temperature of the content contained in the body.
