Described heat exchange dividing plate is connected with the inner wall sealing of tank shell.
The other end of described heat exchange dividing plate is connected on the heat exchanging fin.
One end of described heat exchange dividing plate is connected fire row's air inlet end face or is hung between fiery air inlet end face of arranging and fiery row's the combustion front.
Described heat exchange dividing plate is vertical with staged burners fire row's combustion front.
Described heat exchange dividing plate is connected the inwall of tank shell by welding or riveted and fixed.
Described heat exchange dividing plate is connected the inwall of tank shell by dismountable screw or buckle.
Described heat exchange dividing plate is connected on the heat exchanging fin by welding or riveted and fixed.
Described heat exchange dividing plate is provided with the bending edges that is connected with the tank shell inwall.
Described heat exchange dividing plate is made by stainless steel or copper or the aluminium alloy that is provided with reinforcement.
The utility model is compared the beneficial effect that is produced with background technology: set up the heat exchange dividing plate because the utility model adopts between two sections of staged burners, make gas heater under the situation of low load combustion, high-temperature flue gas only carries out heat exchange through less heat exchange area, improved the exhaust gas temperature under the underload, so it can avoid a large amount of condensed waters to generate effectively, reduced the corrosion and damage of condensed water, guaranteed the service life of water heater critical components such as heat exchangers.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the annexation three-dimensional cutaway view of exhaust fume collecting hood 9 among Fig. 1, heat exchanger 8, staged burners 4, water tank 18 and heat exchange dividing plate 10.
Fig. 3 is the exploded perspective view of Fig. 2.
Fig. 4 is the structural representation that heat exchange dividing plate 10 adopts screw to connect among Fig. 2.
The specific embodiment: shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, present embodiment comprises magnetic valve, staged burners 4, tank shell 6, heat exchanger 8, exhaust fume collecting hood 9, pulse igniter 15, blower fan assembly 16, controller 17, water tank 18, heat exchanger 8 is provided with heat exchanging fin 7, staged burners 4 is provided with fire row 14, be provided with the section gap place between two sections fire rows, it comprises that also an end inserts staged burners fire row 14 section gap place and the heat exchange dividing plate 10 that the side is connected tank shell 6 inwalls.Wherein said magnetic valve is at least two, as second magnetic valve 2, the 3rd magnetic valve 3, and at least two sections fire rows' of control switching respectively.
Magnetic valve described in the present embodiment comprises first magnetic valve 1, second magnetic valve 2 and the 3rd magnetic valve 3, the master control valve that first magnetic valve 1 opens and closes for fuel gas pipeline, the burning of right side fire row section in second magnetic valve, 2 control charts 1, the burning of left side fire row section in the 3rd magnetic valve 3 control charts 1.The inwall of heat exchange dividing plate 10 and tank shell 6 can by welding or riveted and fixed be connected or by dismountable screw or buckle connection, can be provided with the bending edges that is connected with tank shell 6 inwalls on the heat exchange dividing plate 10 so that more firm connection, the junction is best for being tightly connected.The other end of heat exchange dividing plate 10 can by welding or riveted and fixed connects or be connected on the heat exchanging fin 7 by dismountable screw or buckle, and the junction is the best to be tightly connected also.The air inlet end face 12 that one end of heat exchange dividing plate 10 is connected fire row 14 air inlet end face 12 or is hung on fire row 14 and fire are arranged between 14 the combustion front.It is best that one end of heat exchange dividing plate 10 inserts the whole combustion front with staged burners fire row 14 in back, staged burners 4 location vertical.Heat exchange dividing plate 10 is made by high temperature resistant, corrosion-resistant material, as being stainless steel or copper or aluminium alloy, when heat exchange dividing plate 10 aluminium alloys are made, should be provided with reinforcement on the dividing plate; When if the material of water tank 18 is copper, then select the heat exchange dividing plate that is made of copper for use for the ease of welding.The material of heat exchange dividing plate 10 is a stainless steel among Fig. 1, and two ends are provided with bending edges, and the bending edges at heat exchange dividing plate 10 two ends is weldingly fixed on the inwall of tank shell 6.Among Fig. 2 heat exchange dividing plate 10 is fixed on the inwall of tank shell 6 by screw.
During water heater working, water heater normally starts, 16 work of blower fan assembly, and controller 17 control impuls igniters 15 discharge ignitings, magnetic valve is opened simultaneously, and 13 igniting of igniting pin, combustion gas enter each fire row burning of staged burners 4 through each nozzle.When being in big load, first magnetic valve 1, second magnetic valve 2, the 3rd magnetic valve 3 are all opened, this moment, all fire rows 14 were burnt, cavity 11 that high-temperature flue gas surrounds via tank shell 6 and heat exchange dividing plate 10 respectively and cavity 5 enter heat exchanger 8 and carry out heat exchange with heat exchanging fin 7, and the low-temperature flue gas after the heat exchange is outside exhaust fume collecting hood 9 discharge machines.When being in the underload sectional combustion, first magnetic valve 1 and the 3rd magnetic valve 3 are opened, have only left side fire row section burning this moment, the high-temperature flue gas that burning produces enters heat exchanger 8 left sides and less heat exchanging fin 7 carries out heat exchange through cavity 11, and the low-temperature flue gas after the heat exchange is outside exhaust fume collecting hood 9 discharge machines.When being in more underload, first magnetic valve 1 and second magnetic valve 2 are opened, have only right side fire row section burning this moment, the high-temperature flue gas that burning produces enters heat exchanger 8 right sides and less heat exchanging fin 7 carries out heat exchange through cavity 5, and the low-temperature flue gas after the heat exchange is outside exhaust fume collecting hood 9 discharge machines.By under underload, reducing heat exchange area exhaust gas temperature is improved, thereby avoid a large amount of condensed waters to generate effectively, reduced the corrosion and damage of condensed water, guaranteed the service life of water heater critical components such as heat exchangers.
