Abstract: A sensing element is adapted to monitor a temperature of a foodstuff placed within an oven cavity of a cooking utensil such as a microwave oven. The sensing element comprises a thermally-responsive element, an antenna, a double choke, and a trimmer condenser. The double choke is bent so as to provide a double compartment for causing choke operations. The double compartment contains a material the dielectric constant of which is higher than the air. A capacity of the trimmer condenser is adjustable. A resonance circuit or an oscillation circuit may be formed with the thermally-responsive element and the trimmer condenser. A metallic member is disposed adjacent to the antenna. The length of the antenna is selected as an integral multiple of about .lambda./2 (.lambda. is the wavelength of the microwaves).

Abstract: A wireless temperature-sensing assembly adapted for a cooking apparatus such as a microwave oven, comprises a wireless communication element and a sensing probe. The wireless communication element provides electromagnetic waves over an oven cavity of the cooking apparatus. The sensing probe selects a particular frequency of the electromagnetic waves. The sensing probe contains an oscillator element resonance frequencies of which vary depending on the surrounding temperature. The wireless communication element further receives and detects the particular frequency of the electromagnetic waves defined by the selecting means. In a specific form, the wireless communication element provides the electromagnetic waves the frequencies of which vary from time slot to time slot. The oscillator element may be composed of crystal, ceramic, or the like. The resonance frequencies of the oscillator element change due to variation in its number of proper vibrations dependent on the surrounding temperature.
