ABSTRACT:
An infrared heater for heating a cooking vessel, such as a Chinese wok. The heater includes a block of refractory material, which emits infrared radiation upon heating to an elevated temperature, forming an inverted frustum-shaped cavity or opening. A gas-fired burner having a burner head which produces a laterally directed flame upon ignition of a mixture of a fuel gas and a combustion oxidant supplied to the burner is disposed in the cavity or opening. A planar structure suitable for emitting infrared radiation upon heating to an elevated temperature and forming at least one centralized opening covers the upward oriented base end of the inverted frustum-shaped opening. In accordance with one embodiment, the refractory block is disposed within a cylindrical housing which supports the cooking vessel above the centralized opening during the cooking process.
