The gas ignition control system consists of an igniter, a fan, an air quantity valve, a first lead, a gas pipe, a switch and a second lead, wherein the igniter is arranged on the gas stove and is connected with the switch through the second lead; the fan is arranged at the bottom of the cooking bench, a power line of the fan is connected with the switch, the air outlet is connected with the gas stove through a pipeline provided with an air quantity valve, and the gas pipe is connected with the gas stove.

The automatic water inlet switch on the water tank consists of a floater, a water pipe and an automatic valve, wherein the floater is connected with the automatic valve through a connecting rod, and the automatic valve is connected with the water pipe.

The kitchen range is characterized in that a filter screen is arranged on the edge of the kitchen range, and a waste water pipe is arranged on one side below the filter screen.

The utility model relates to a theory of operation of restaurant kitchen range with heat recovery: 1) the air supply valve is opened first, then the switch is pressed, and the igniter and the fan work simultaneously.

2) When the hot water switch is turned on to discharge water to a certain position, the float sinks to open the valve to feed water, and when the water level rises to a certain position, the float closes the automatic valve.

The utility model relates to a restaurant kitchen range's innovation point with heat recovery lies in, install in the periphery of furnace chamber and the oven and be used for retrieving thermal water tank, the chimney passes the water tank in the oven, just so absorb the heat that furnace chamber wall and chimney effused simultaneously by the water in the water tank, because restaurant kitchen range generally is longer at noon and evening operating time, water in the water tank is just heated very fast, this hot water winter can be for indoor heating installation hot water heating, also can wash food and beverage equipment with hot water, great improvement is to kitchen range heat recovery's utilization efficiency.
