A reservoir of a liquid heating appliance includes a first chamber and a second chamber, separated by a partition. A heating arrangement is arranged to heat liquid in the first chamber. A first valve, a second valve and a float valve are disposed in the partition to selectively allow liquid to flow between the first and second chambers. Respective lines joining the first and second valves to a center of the partition have an obtuse angular separation. The first and second valves are selectively closed by a valve closure member. The float valve includes a floating valve member arranged to float and mate with a valve seat to prevent the flow of liquid. A liquid outlet in the first chamber connects with a dispense outlet on the appliance to allow liquid to be dispensed when the first and second valves are closed.

A temperature sensor fitting for use with a temperature sensor that detects the temperature of ingredients that are inside a heating vessel of a kitchen device, the temperature sensor fitting comprising: a collar comprising an inner threaded portion; a PTFE insulator comprising an outer threaded portion that corresponds with the inner threaded portion of the collar, and further comprises an inner threaded portion; a metal cap comprising an outer threaded portion that corresponds with the inner threaded portion of the PTFE insulator; wherein the PTFE insulator provides thermal isolation between a temperature sensor and a heating plate of the kitchen device; and wherein the collar comprises an outer surface that corresponds with an edge of a floor of a heating vessel of a kitchen device and the outer surface is suitable for welding to the edge of the floor to form a weld seal.

A continuous boiling water preparation method based on gas-liquid two-phase object detection comprises a flow regulator, a heater, a temperature sensor, a two-phase object detection sensor and a controller; the flow regulator is used for injecting a cold water flow obtained from the outside into a water inlet of the heater; the heater heats up according to heating power provided by the controller; the two-phase object detection sensor and the temperature sensor are connected behind a water outlet of the heater, and when a boiling water flow flows through the two sensors, a gas-liquid ratio signal and a temperature signal are obtained respectively, and transmitted to the controller; and the controller transmits a signal indicating required heating power to the heater or transmits a signal indicating a required flow value to the flow regulator through calculation to execute output after receiving the gas-liquid ratio signal.

The present invention discloses a heating device for a kettle, comprising an enclosure, a radiator fan, a rack, a core PCB, a wire coil, and a temperature sensor in the enclosure. A heating platform which has a housing cavity is arranged on the upper part of the enclosure. The radiator fan is mounted at the bottom of the enclosure. The rack is fixed inside the enclosure. The core PCB is configured in the lower part of the rack and above the radiator fan. The wire coil which is provided with a heat coil is installed on the rack, and the temperature sensor is electrically connected with the core PCB.

A pitcher for safely receiving, transporting and decanting a hot liquid includes a body with first and second openings, and a bottom cover removably attached to the body. An opening baffle near the first opening reduces the hot liquid flow rate through the first opening during decanting, and a funnel near the second opening directs the hot liquid through the second opening when receiving the hot liquid. The funnel directs the hot liquid from the second opening to the first opening opening if the hot liquid exits the second opening during decanting. The pitcher includes an elongated handle, a fin for dividing the hot liquid during decanting, and a scalloped outer sidewall for limiting contact with a user's hand.

Systems and methods are disclosed that include providing a cooking system that comprises a burner assembly and a heat exchanger, the burner assembly having a high velocity burner configured to provide the necessary high velocity, volumetric flowrate through the heat exchanger, and the burner assembly also having a low velocity burner configured to significantly reduce and/or substantially eliminate lift off that could result from operation of only the high velocity burner.

A window assembly (3) for a container (1), comprising a window unit (5) adapted to be inserted in a window opening (2) of a container body (4), the window unit (5) comprising an outer facing side (10), an inner facing side (12) and a profiled circumferential edge (14), wherein a portion of the circumferential edge (14) adjacent the outer facing side (10) comprises a rising ridge (16) which acts to limit insertion of the window unit (5) into the window opening (2). It also relates to a container (1) with such window assembly (3), and the method of assembling such window assembly (3) with the container (1).
