Embodiment Construction

[0019] Some example embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Rather, the examples described and illustrated herein should not be construed as limiting the scope, applicability, or configuration of the disclosure; rather, these example embodiments are provided so that this disclosure will satisfy applicable legal requirements. The same reference numerals refer to the same elements throughout. Furthermore, as used herein, the term "or" is to be interpreted as a logical operator that yields true if one or more of its operands are true. As used herein, operatively coupled shall be understood to refer to an indirect or direct connection, which in either case results in a functional interconnection of interoperably coupled components.

[0020] Some example embodiments may improve the defrosting and / or cooking performance of a food preparation device, and / or may improve...

Abstract

A food preparation device may include a radio frequency (RF) capacitive heating source, a liquid temperature control assembly, a cooking controller operably coupled to the RF capacitive heating source and the liquid temperature control assembly, a basin configured to contain a liquid and receive a food product, and a lid hingedly attached to the basin. The lid may be configured to have a function related to a selected food preparation program. The RF capacitive heating source may include a ground plate and an anode or High Voltage (HV) plate disposed on opposing surfaces of the basin.

Description

technical field [0001] Example embodiments relate generally to food preparation devices, and more particularly, to multifunctional radio frequency (RF) capacitively heated food preparation devices. Background technique [0002] Common defrosting applications rely on the conduction of heat from the surface to the interior to provide defrosting. Due to freshness and product quality constraints, thawing is usually performed by immersion in a water bath which itself is only slightly above freezing, or by immersion in a refrigerator set at just above freezing (e.g., 35°F to 40°F). Thawing times are often extremely long and result in a significant loss of food quality and integrity. Thawing can be performed more quickly by capacitive heating techniques that heat evenly over the entire volume ("volume heating"). RF capacitive heating can be used to defrost food in ambient conditions. However, use of a capacitive RF system in an ambient environment results in a significantly fas...
