The disclosed technology includes a hose nozzle assembly with apertures sized to facilitate heating groundwater based on the expected temperature of the groundwater. The hose nozzle assembly can have a handheld enclosure having a handle portion connected to a body portion, a heating chamber having a heating element configured to heat a fluid, and a spray nozzle. The spray nozzle can include a first aperture configured to provide a first spray pattern at a first flow rate corresponding to a first change in temperature of fluid flowing through the heating chamber and a second aperture configured to provide a second spray pattern at a second flow rate corresponding to a second change in temperature of fluid flowing through the heating chamber. The second flow rate can be less than the first flow rate and the second change in temperature can be greater than the first change in temperature.

A cooking engagement system and methods for providing recipe content to a user are provided. The system includes a cooking appliance and an interactive assembly positioned above the cooking appliance. The interactive assembly includes a display device that presents various content to a user, e.g., recipe content. In one example aspect, a user submits a recipe request. The recipe request is routed to one or more third party recipe content providers. A controller of the interactive assembly obtains recipe content from the recipe content providers and causes a display device of the interactive assembly to present the recipe content to the user.

A method for controlling a cooking temperature within a cooking appliance is described. The preferred method includes setting a desired cooking temperature (T) for the cooking appliance via a temperature setting input, and operating the heating element to raise an internal temperature within the cooking chamber based on a power input strategy. Preferably, the power input strategy includes selecting an initial power (PO) between 50% and 100% power, powering the heating element at the initial power using an on/off cycle of N milliseconds based on the formulas:

on time=(P.sub.i).Math.N milliseconds; and

off time=(100−P.sub.i).Math.N milliseconds;

then, reducing the initial power to a reduced power (P.sub.r) as the rising internal temperature within the cooking chamber approaches the desired cooking temperature, wherein the reduced power (P.sub.r) is between 1% and 99% power. Finally, the desired temperature is maintained within the cooking chamber.

A range has burner coil elements which have temperature switches as a portion of the replaceable coils. Upon reaching a predetermined temperature, the switch opens and power through the burner element is secured. The burner elements are preferably open coil units. Lowering the temperature in a cooking utensil below common ignition temperatures while still allowing boiling is an objective of many embodiments.

An assembly for magnetic induction or magnetocaloric heating of a cooktop surface. One or more magnetic/electromagnetic plates are rotated by a motor or other rotary inducing input in proximity to a stationary supported magnetocaloric heating material conductive plate. Joule heating and eddy currents are generated through oscillating of magnetic fields at a given frequency when magnets/electromagnets rotate, and which is conducted through the magnetocaloric heating material via conduction and emanates from an exposed surface thereof. Conventional heating elements, such as resistor coils, are integrated into the magnetocaloric cooktop material in order to provide fast initial heat up of the materials and can be de-powered once inductive heating of the magnetocaloric material achieves desired performance levels. The housing interior can be sealed and contain a volume of any type of thermal fluid oil, lubricant or refrigerant or any other fluid with high specific heat capacity and high boiling point for providing any heat transfer properties.

A cooking plate includes a metal plate for cooking; a heating element, which is in contact with the metal plate and is configured to heat the metal plate; and a temperature sensing element which is integrated with the metal plate and which is configured to sense a temperature of the metal plate and outputs a sensing signal for control heating of the heating element.

A cooking control system having a temperature probe and a cooking appliance is described for permitting temperature target cooking of foods. The probe includes a metallic insertable portion with a sheathed tip and a temperature sensor positioned therein, a flexible heat-resistant wire coupled to the temperature sensor, and a jack coupled to the flexible, heat-resistant wire opposite the metallic insertable portion. The cooking appliance includes a heating unit, an housing, a temperature reader, and an alpha-numerical display. In use, the temperature sensor produces a signal in response to a temperature sensed at the sheathed tip and the heat-resistant wire and jack transmit the signal produced by the temperature sensor to the port of the cooking appliance. The temperature reader within the housing is coupled to the port and configured to accept and accurately convert the signal produced by the temperature sensor to a number representing the temperature sensed by the sensor and display the number for the user.

A switch for operating a heating element of a cooking appliance includes a first contact electrically connected with the heating element, a second contact electrically connected with a power source. A bimetal strip is configured to electrically connect and disconnect the first and second contacts. The switch further includes a rotatable cam member having a cam surface for operative engagement with a cam follower. The cam surface has a profile dimension that is at least partially variable about the rotational axis of the cam member and is configured to cause displacement of the cam follower as a function of its rotational orientation to thereby adjust an operating temperature of the heating element. The cam surface is configured such that the operating temperature can be adjusted up to but not beyond a predetermined maximum temperature via rotation of the cam member. Circuits incorporating such a switch also are disclosed.

A circuit for driving a cooker includes a sensing unit configured to sense a movement of a user of a cooker. The circuit further includes a contact unit configured to switch a power circuit to which power is supplied from the outside, and perform a closing operation on the basis of a sensing result from the sensing unit to allow power to be supplied to the cooker.

The invention refers to a method for controlling an electric appliance, in particular an electric household appliance (1, 11, 12). The electric appliance is coupled to an electric supply system, particularly to a line section (13) of an electric supply system. The electric supply system has a, preferably fuse-protected, limited electrical power transfer capacity. The electric appliance is operated by an operating program, which comprises at least one program segment during which relevant electrical power consumption is drawn from the electric supply system, particularly from the line section (13) of the electric supply system. The operating program is controlled based on at least one of:the electrical power currently providable by the electric supply system;the electrical power allocatable to the electric appliance by the electric supply system at present or on short notice;the voltage value or amperage value currently existent in the electric supply system during the operation of the electric appliance;a voltage drop or voltage difference or an amperage change currently occurring in the electric supply system at the moment of starting an operating program with relevant electrical power consumption;a result of a comparison of a measured energy consumption information with a reference energy consumption information.
