With the increasing demands of people on life quality, cookers have become essential living goods basically.

In order to improve cooking efficiency, existing cooktops are typically provided with an intake manifold and a plurality of burner assemblies, each connected to the intake manifold. In this way, the combustion gases may pass through the intake manifold and then into the various burner assemblies, respectively, for combustion.

However, the connection between the plurality of burner assemblies and the intake manifold is as follows: the same air inlet main pipe is shared, the connection points of the plurality of burner assemblies and the air inlet main pipe are sequentially distributed along the air conveying direction of the air inlet main pipe, and as the pressure of fuel gas in the air inlet main pipe is reduced along the air conveying direction of the air inlet main pipe, the pressure in different positions of the air inlet main pipe is different, the pressure distribution in the air inlet main pipe is easy to generate an unbalanced phenomenon, and the air inlet pressure entering each burner assembly is greatly different. The gas discharge flow rate of the burner assembly is easily changed, thereby affecting the ability to inject primary air. In this way, the flame condition of each burner assembly is susceptible to change, thereby directly affecting the condition and/or thermal efficiency of the flue gas, and the stability of combustion is poor.

In this way, the gas injection flow rates of the individual burner assemblies 200 can be kept uniform, so that the combustion state can be kept uniform. By such arrangement, deviations in the smoke state and/or thermal efficiency of the respective burner assemblies 200 can be avoided, so that the combustion stability can be ensured to be good. Therefore, the stability of the kitchen range is better.

Illustratively, the shunt 300 may include a connection 330. The intake manifold 100 may be provided with a connection fitting 110. The connection part 330 and the connection fitting part 110 may be screw-coupled. In this way, the splitter 300 may be threadably coupled to the intake manifold 100. So configured, the strength of the connection of the flow splitter 300 to the intake manifold 100 is high. Also, the sealability between the flow divider 300 and the intake manifold 100 is good, so that the risk of occurrence of air leakage can be prevented.

Illustratively, the cross-sectional flow area of the inlet manifold 230 is less than the cross-sectional flow area of the inlet manifold 100. Since the gas is split after passing through the splitter 300, the flow rate of the gas passing through one of the inlet branches 230 may be smaller than the flow rate of the gas passing through the inlet manifold 100. Therefore, the flow cross-sectional area of the air inlet branch pipe 230 can be properly reduced, so that the consumable material can be reduced, and the manufacturing cost of the kitchen range can be reduced.

Illustratively, the outlet passageway 320 may have an internally threaded section 324 formed thereon. The end of the inlet manifold 230 remote from the inlet port may have an externally threaded section (not shown). The male threaded section and the female threaded section 324 may be connected. In this way, the inlet manifold 230 may be threadably connected to the splitter 300. So arranged, the strength of the connection of the inlet manifold 230 and the splitter 300 is high. Also, the sealability between the inlet branch pipe 230 and the flow divider 300 is good, so that the risk of occurrence of air leakage can be prevented.

Illustratively, the cooktop may also include a bottom shell 400. At least a portion of the flow splitter 300 may be located above the bottom chassis 400. Intake manifold 100 may be located below bottom shell 400. So configured, intake manifold 100 may be unaffected by bottom shell 400, and may thus facilitate connection to a fuel gas source.

For example, a pipe joint 120 may be provided on the intake manifold 100. The connection fitting 110 may be a screw hole provided on the pipe joint 120. The connection 330 may be configured as a stud. The studs may penetrate out of the bottom chassis 400 vertically downward from above the bottom chassis 400 and then be connected to the screw holes. So configured, the strength of the connection of the flow splitter 300 to the intake manifold 100 is high. Also, the sealability between the flow divider 300 and the intake manifold 100 is good, so that the risk of occurrence of air leakage can be prevented.

Illustratively, the head 340 and the bottom chassis 400 may be connected by fasteners. Fasteners include, but are not limited to, screws, bolts or rivets. Thus, the head 340 and the bottom case 400 can be relatively fixed, and the stability of the kitchen range is better.

Illustratively, the head 340 of the splitter 300 may be provided with a threaded bore 343. The screw hole 343 may extend from the end surface 341 in a direction parallel to the intake passage 310. The number of threaded holes 343 may be any number including, but not limited to, two as shown in the figures, for example, one, three, or others. The bottom chassis 400 may have a coupling hole (not shown) thereon corresponding to the screw hole 343. The fastener may be coupled to the threaded hole 343 through the coupling hole. The fastener may be a threaded fastener such as a screw. So arranged, the strength of connection between the head 340 and the bottom chassis 400 is high, and connection and disconnection are facilitated.
