In one embodiment, the segmenting device 1 is composed of a connecting plate 11 and a buckle plate 12 for sealing the connecting plate 11, three air passage grooves are formed in the connecting plate 11, a first air passage 3, a second air passage 4 and a third air passage 5 are respectively formed between the buckle plate 12 and the connecting plate 11, the first air passage 3 is communicated with the diverter 2 through a first through hole 31, the second air passage 4 is communicated with the diverter 2 through a second through hole 41, the third air passage 5 is communicated with the diverter 2 through a third through hole 51, the proportional valve 21 is communicated with the first air passage 3 through the first through hole 31, the first valve 22 is selectively connected with the second through hole 41 in a sealing mode, the second valve 23 is selectively connected with the third through hole 51 in a sealing mode, and the first air passage 3, the second air passage 4 and the third air passage 5 are respectively communicated with the diverter 2 through the first through hole 31, the second through hole 41 and the third through hole 51.
The first air passage 3, the second air passage 4 and the third air passage 5 are respectively provided with a connecting nozzle 13, and are connected with the burner through the connecting nozzles 13. A sealing frame 14 is arranged between the pinch plate 12 and the connecting plate 11, and the sealing frame 14 is used for separating and sealing the first air passage 3, the second air passage 4 and the third air passage 5. The second through hole 41 has a larger aperture than the first through hole 31 and smaller aperture than the third through hole 51. The number of the connecting nozzles 13 on the third air path 5 is larger than the number of the connecting nozzles 13 on the second air path 4, and the number of the connecting nozzles 13 on the second air path 4 is not smaller than the number of the connecting nozzles 13 on the first air path 3.
The technical scheme has the working principle and beneficial effects that: the embodiment provides an implementation mode capable of accurately adjusting the water temperature under the condition that the water flow is unchanged.
Taking the sectional combustion mode of two combustion chambers as an example (the principle of a single combustion chamber is the same as that of two or more hot combustion chambers), when two combustion chambers are arranged, the connecting nozzle 13 of the first air path 3 and the second air path 4 are communicated with the first combustion chamber, and the connecting nozzle 13 of the third air path 5 is communicated with the second combustion chamber.
When rapid temperature rise is required, the controller on the water heater can open the proportional valve 21 to the maximum with the water switch open, and simultaneously the first valve 22 and the second valve 23 are all open. The fuel gas can enter three gas paths and two combustion chambers respectively through the flow divider 2 so as to realize rapid temperature rise of water in the water heater.
When the required water temperature is low and only one combustion chamber needs to be opened, the controller of the water heater can open the first valve 22 and keep the second valve 23 closed, and the fuel gas can enter the first combustion chamber through the first gas path 3 and the second gas path 4.
When it is desired to further reduce the water temperature, the controller of the water heater keeps the first valve 22 and the second valve 23 closed. The combustion gases enter the combustion chamber directly from the first gas circuit 3.
The proportional valve 21 can control the delivery flow rate of the fuel gas, and the apertures of the first through hole 31, the second through hole 41 and the third through hole 51 are gradually increased, so that the amount of the fuel gas entering the third gas passage 5 can be close to the sum of the amounts of the fuel gas of the first gas passage 3 and the second gas passage 4 under the condition of the same delivery amount of the fuel gas, and therefore, under the condition that three gas passages are used simultaneously, the two combustion chambers can be basically maintained at the same combustion power.
Through the design of the structure and the cooperation with the proportional valve 21, the fire control range can be greatly increased, so that the water temperature can be controlled more accurately.
In order to ensure the tightness among the three air channels, clamping grooves for arranging the sealing frame 14 are arranged at the outer edges of the three air channels of the connecting plate 11 so as to realize mutual independence among the three air channels.
In one embodiment, the first through hole 31, the second through hole 41 and the third through hole 51 are respectively provided with a trigger rod 6 and a rotatable gas indicating device 7, the gas indicating device 7 and the trigger rod 6 are respectively located in the gas path groove of the connecting plate 11, the clamping plate 15 is arranged in the gas path groove of the connecting plate 11, the gas indicating device 7 is selectively abutted to the clamping plate 15, the trigger rod 6 is located on one side, away from the connecting nozzle 13, of the clamping plate 15, and the trigger rod 6 is selectively abutted to the gas indicating device 7.
The gas indicating device 7 is tubular, two ends of the gas indicating device are respectively connected with the connecting plate 11 and the pinch plate 12 through torsion springs, an air inlet is formed in the side wall of the gas indicating device 7, an abutting plate 71 is arranged on one side of the air inlet, one side, away from the air inlet, of the abutting plate 71 is selectively abutted to the trigger rod 6, one side, close to the air inlet, of the abutting plate 71 is selectively abutted to the clamping plate 15, the abutting plate 71 is arc-shaped, and the abutting plate 71 extends to the outer side of the air inlet.
The technical scheme has the working principle and beneficial effects that: the trigger lever 6 can be connected with a controller in the water heater, and when the abutting plate 71 contacts the trigger lever 6, the controller can identify whether gas leakage exists or not and whether the second gas channel 4 and the third gas channel 5 need to be opened or not according to whether the gas channel is in a gas supply state or not.
Taking the mode of setting two combustion chambers to burn in a sectional manner as an example, before air supply, under the action of a torsion spring, the abutting plate 71 abuts against the clamping plate 15, and the air inlet is sealed by the clamping plate 15, at the moment, the clamping plate 15 is positioned between the air inlet and the abutting plate 71, as shown by A in fig. 9, along with the entering of the fuel gas, the fuel gas enters into the first air path 3 through the air inlet, at the moment, when the fuel gas enters into the first air path 3 from the air inlet, the arc abutting plate 71 is pushed, the fuel gas indicating device 7 is enabled to rotate, at the moment, the abutting plate 71 is separated from the clamping plate 15, and rotates towards the triggering lever 6, and the torsion spring starts to bear force, as shown by B in fig. 9. The control of the water heater still keeps the first valve 22 and the second valve 23 closed.
If the water temperature is insufficient, and fuel gas needs to be continuously supplied, the proportional valve 21 can provide more fuel gas, and the gradually-increased fuel gas can push the fuel gas indicating device 7 to continuously rotate until the abutting plate 71 abuts against the trigger rod 6, as shown by C in fig. 9, at this time, the controller in the water heater recognizes that the fuel gas supply in the first air path 3 is maximized through the trigger rod 6.
When the water temperature needs to be further increased, the controller in the water heater can open the first valve 22, so that the fuel gas can enter the first combustion chamber through the second gas path 4, and the fuel gas indicating device 7 in the second gas path 4 starts to rotate.
Until the gas indicating device 7 in the second gas circuit 4 is abutted on the trigger rod 6, the controller in the water heater can open the second valve 23 and open the second combustion chamber, so that further water temperature adjustment is realized.

The technical scheme has the working principle and beneficial effects that: as shown in fig. 2, since the present invention adopts an integrated arrangement mode, in order to facilitate the processing of the connection plate 11 and the assembly of the whole water heater, the connection nozzles 13 are generally arranged on the same straight line, which brings convenience to installation and equipment planning, but when the air is supplied, the situation that some connection nozzles 13 are close to the through holes and some connection nozzles 13 are far away from the through holes occurs, as shown in fig. 4, some connection nozzles 13 on the third air path 5 are close to the third through holes 51 and some connection nozzles are far away, so that when the combustion chamber burns, the difference of the air supply flow rate of the connection nozzles 13 positioned in the same air path often occurs, flame flashover phenomenon and sound occur when the combustion chamber burns, and thus flame in the combustion chamber of the water heater heats the heat pipe unevenly, and meanwhile, the situation is similar to the flashover phenomenon often occurring when the air supply of the gas cooker is uneven.
In order to improve the situation, the invention adds the pressure stabilizing device 8 in the connecting nozzle 13 to make the gas flow and pressure delivered by the connecting nozzle 13 in the same gas path approach the same.
Taking the third air path 5 as an example, when air is supplied, the reducing baffle 86 in the pressure stabilizing device 8 is located at the connection position of the top pipe 81 and the tail pipe 82 in the connecting nozzle 13 far away from the third through hole 51, as shown in fig. 13D, that is, the position with the largest inner diameter in the pressure stabilizing device 8, and the flow area of the fuel gas is the largest. In the connection nozzle 13 closer to the third through hole 51, the diameter-variable baffle 86 in the pressure stabilizing device 8 is pushed into the top pipe 81 under larger gas pressure, and as shown in fig. 13E, because the inner diameter Rm of the middle part of the top pipe 81 is smaller than the inner diameter Rt of the end part thereof, the distance between the diameter-variable baffle 86 and the inner wall of the top pipe 81 becomes smaller, so that the gas flow area becomes smaller, and more gas flows to the connection nozzle 13 at a far position.
Through the design of above-mentioned structure for all can set up a plurality of connecting mouths 13 in every gas circuit, increase the combustion area, and can effectively reduce the noise that produces because of the spark, avoid the inhomogeneous problem of heating of flame to the heat pipe in the combustion chamber simultaneously.
