초록 ▼

The invention is directed to an arrangement for adjusting a pressure-fluctuation free supply of gas and for controlling an operating pressure of an air/gas mixture to a radiation-gas burner of a gas cooking apparatus. The radiation-gas burner has a burner chamber and is mounted in a housing below a cover plate. The arrangement includes a gas supply conduit connectable to a gas source for receiving the gas and a pressure controller is mounted in the gas supply conduit for controlling the pressure of the gas to a constant operating pressure of at least 2.5 mbar above atmospheric pressure. A control unit is connected to the pressure controller for receiving the pressure-controlled gas and for metering the gas to the radiation-gas burner. The control unit includes a valve block having at least one exchangeable nozzle adapted to the type of gas from the gas source and a feed conduit has a clear cross-sectional area and communicates with the burner chamber. The feed conduit has an inlet opening adjacent the nozzle. A blower blows air into the apparatus to generate an overpressure whereby the gas metered by the control unit through the nozzle entrains air to form an air/gas mixture entering the feed conduit. An insert is mounted in the feed conduit for reducing the cross-sectional area of the feed conduit. The insert is selected so as to reduce the cross-sectional area to enable the radiation-gas burner to operate at a predetermined efficiency irrespective of the fluctuations in the pressure of the gas and the changes in type of the gas.

대표청구항 ▼

[ What is claimed is:] [1.] A cooking assembly which is supplied from a gas source supplying a gas which fluctuates in pressure and changes in type, the cooking assembly comprising:a housing;a cover plate mounted atop said housing to close said housing and define a continuous cooking surface;a radiation-gas burner mounted in said housing below said cover plate;said radiation-gas burner having a burner chamber; and,an arrangement for providing a pressure-fluctuation free supply of said gas and for controlling an operating pressure of an air/gas mixture to said radiation-gas burner, said arrangement including:a gas supply conduit connectable to said gas source for receiving said gas;a pressure controller mounted in said gas supply conduit for controlling the pressure of said gas to a constant operating pressure of at least 2.5 mbar above atmospheric pressure;a control unit connected to said pressure controller for receiving the pressure-controlled gas and for metering said gas to said radiation-gas burner;said control unit including a valve block having at least one exchangeable nozzle adapted to the type of gas from said gas source;a feed conduit having a clear cross-sectional area and communicating with said burner chamber;said feed conduit having an inlet opening adjacent said nozzle;blower means for blowing air into said housing to generate an overpressure therein whereby said gas metered by said control unit through said nozzle entrains air to form an air/gas mixture entering said feed conduit for combustion in said burner;an insert mounted in said feed conduit for reducing said cross-sectional area of said feed conduit;said insert being selected so as to reduce said cross-sectional area to enable said radiation-gas burner to operate at a predetermined efficiency irrespective of the fluctuations in said pressure of said gas and said changes in type of said gas;a carrier plate; and,said pressure controller, said control unit and said gas supply conduit all being mounted in common on said carrier plate to form a single component assembly unit mounted in said housing.
