A gas distribution lever assembly 40 for a gas water heater 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 7.
As shown in fig. 1, the rear case 10 of the gas water heater 100 has a mounting surface for mounting functional modules such as a blower fan, a water tank 20, a burner 30, a gas distribution lever assembly 40, and a gas proportional valve 50.
As shown in fig. 1, the gas distributing rod assembly 40 is located at the lower part of the burner 30, the gas injection holes 45 of the gas distributing rod assembly 40 are disposed opposite to the gas inlet of the burner 30, the gas distributing rod assembly 40 delivers gas to the burner 30, the gas and the air are mixed from the inside of the burner 30, then the ignition structure ignites, the gas mixture starts to burn, a large amount of flue gas is generated to heat the water tank 20, and the low-temperature flue gas subjected to heat exchange is discharged to the outside.
The gas distribution lever assembly 40 according to the embodiment of the present invention includes: a first body 41 and a second body 42.
Specifically, the first body 41 is divided into a first air passage 411 and a plurality of second air passages 412 that are independent of each other, and the first body 41 is provided with a plurality of air ejection holes 45, and the air ejection holes 45 are respectively communicated with the first air passage 411 and the second air passages 412. The second body 42 is connected to the bottom of the first body 41, and the second body 42 defines a third air channel 421. As shown in fig. 1 in combination with fig. 2 to 4, the first body 41 and the second body 42 are stacked from top to bottom, the air injection holes 45 are formed on one side of the first body 41 facing the burner 30, and when the gas water heater 100 works, the gas enters the third air passage 421 in advance, then flows to the first air passage 411 and the second air passage 412 respectively, and is delivered to the burner 30 through the corresponding air injection holes 45.
The first air passage 411 and the second air passage 412 are both communicated with the third air passage 421, wherein an intake air amount per unit time of one of the first air passage 411 and the second air passage 412 is adjustable. That is, the intake air amount per unit time of the first air passage 411 and the second air passage 412 may be adjusted, or the first air passage 411 may be adjusted, the second air passage 412 may not be adjusted, or the first air passage 411 may not be adjusted, and the second air passage 412 may be adjusted.
It is understood that in the case where both the first air passage 411 and the second air passage 412 are turned on, the total intake air amount per unit time of the burner 30 is equal to the sum of the output air amounts per unit time of the first air passage 411 and the second air passage 412. Accordingly, when the gas water heater 100 is operated, the total intake air amount per unit time of the burner 30 can be increased or decreased by adjusting the intake air amount per unit time of the first air passage 411 and/or the second air passage 412.
When the intake air amount per unit time of the first air passage 411 and the second air passage 412 reaches the maximum value, the intake air amount per unit time of the burner 30 is maximum; when the intake air amount per unit time of the first air passage 411 and the second air passage 412 is minimum, the intake air amount per unit time of the burner 30 is minimum.
Therefore, according to the gas distribution rod assembly 40 for the gas water heater 100 of the embodiment of the invention, since the first body 41 is provided with the first gas passage 411 and the plurality of second gas passages 412, when the gas water heater 100 works, the fire power adjusting range of the burner can be increased by adjusting the air inflow of the first gas passage 411 and/or the second gas passages 412, so as to further meet different requirements of users on water temperatures.
In some embodiments of the present invention, as shown in fig. 2, the first air passage 411 and the second air passage 412 are opened downward, the third air passage 421 is opened upward, a partition plate 43 is provided between the first body 41 and the second body 42, and the partition plate 43 is provided with a communication hole 431 for communicating the first air passage 411 and the third air passage 421, the second air passage 412 and the third air passage 421. That is, the partition plate 43 divides the gas distributing rod assembly 40 into the first body 41 located at the upper side and the second body 42 located at the lower side, the upper surface of the partition plate 43 is attached to the bottom surface of the first body 41, the lower surface of the partition plate 43 is attached to the top surface of the second body 42, wherein the bottom surface of the first body 41 is provided with the partition plate 414, the partition plate 414 divides the first body 41 into the first air passage 411 and the second air passage 412 which are independent of each other, and the partition plate 43 is clamped between the first body 41 and the second body 42 to perform sealing and isolation functions.
In an alternative embodiment, as shown in fig. 4 and fig. 5, a first mounting seat 422 and a second mounting seat 423 are respectively disposed at positions of the second body 42 opposite to the communication hole 431, wherein the first mounting seat 422 is used for mounting the electromagnetic valve, and the second mounting seat 423 is used for mounting the air inlet pipe 44. The amount of intake air from the third air passage 421 into the second air passage 412 is adjusted by the solenoid valve. In other words, in this embodiment, the first air passage 411 and the third air passage 413 are always kept in communication, and the flow rate of the third air passage 413 into the second air passage 412 can be regulated by the electromagnetic valve. That is, when the gas water heater 100 is operated, the first air passage 411 and the third air passage 413 are in a normally open state, and the amount of air output per unit time of the gas lever assembly 40 is increased or decreased by adjusting the amount of air input to the second air passage 412.
In a further alternative embodiment, the first mount 422 and the second mount 423 are respectively formed at the bottom of the second body 42 and extend downward. In this way, the solenoid valve and the air inlet pipe 44 are conveniently installed and removed, and the assembling and maintaining efficiency of the air distribution rod assembly 40 is improved.
In an alternative embodiment, the first mount 422 and the second mount 423 are downwardly extending cylindrical tubes. As shown in fig. 2 and fig. 4, the positioning lugs with the mounting holes are formed on the peripheral wall of the cylindrical tube, and the electromagnetic valve and the air inlet tube 44 can be provided with mounting structures matched with the positioning lugs, so that the electromagnetic valve and the air inlet tube 44 can be mounted and dismounted more conveniently.

That is, the gas in the third gas passage 421 may enter the longitudinal branch 462 through the communication hole 431, and then flow from the longitudinal branch 462 to the lateral branch 461 in a dispersed manner. In other words, the first air passage 411 and the second air passage 412 realize the simultaneous air delivery to the plurality of lateral passages through the longitudinal branch passage 462, thereby increasing the total air delivery area of the first air passage 411 and the second air passage 412, that is, increasing the total air delivery area of the gas distributing lever assembly 40, and more uniformly delivering the air to the burner 30.
In some alternative examples, each of the lateral branches 461 corresponds to a set of gas injection holes 45. That is, both the first air passage 411 and the second air passage 412 may simultaneously feed air to the burner 30 through the plurality of groups of air injection holes 45.
In other alternative examples, two adjacent transverse legs 461 are spaced apart. Thus, the total gas delivery area of the gas distribution rod assembly 40 is further increased, and the gas can be more uniformly delivered to the burner 30.
In a further alternative embodiment, as shown in FIG. 6, the second air passage 412 includes a left air passage and a right air passage, which are positioned to the left and right of the first air passage 411, respectively. That is, a part of the gas entering the third gas passage 413 enters the first gas passage 411, and another part of the gas flows into the second gas passages 412 on the left and right sides, respectively.
Namely, when the gas water heater 100 works, gas can be simultaneously conveyed to the burner 30 through the first gas passage 411 and the left and right second gas passages 412, and the gas outlet amount of the gas distributing rod assembly 40 in unit time can be accurately regulated by regulating the first gas passage 411 and the left and right second gas passages 412, so that the fire power of the burner 30 is effectively controlled. It should be understood that the number of the second air passages 412 and the arrangement of the first air passages 411 and the second air passages 412 are merely illustrative, and not limiting the scope of the present invention, for example, the cross section of the air dividing rod assembly 40 may be circular, where the first air passages 411 may be located at a central position, and the second air passages 412 are radially distributed in the circumferential direction of the first air passages 411.
In one embodiment of the present invention, as shown in fig. 6, the first air passage 411 and the second air passage 412 each include: three transverse legs 461 and one longitudinal leg 462. Wherein the longitudinal branches 462 are each located in the horizontal middle of the first air duct 411 and the second air duct 412. In other words, the first air passage 411 and the second air passage 412 are substantially in a grid shape, thereby facilitating the production and processing of the gas distribution stem assembly 40. It should be understood that the foregoing is illustrative only and is not intended to limit the scope of the present invention, and that the specific number and arrangement of the transverse legs 461 and the longitudinal legs 462 is not limited, so long as the increase in the gas delivery area of the gas distribution lever assembly 40 is achieved.
Optionally, the lateral branches of the first airway and the second airway lie on a same straight line. Thereby, the processing and manufacturing of the first body 41 are facilitated, and the production cost of the gas distributing rod assembly 40 is reduced.
Optionally, the ratio of the number of air holes 45 in each row of the left air passage, the first air passage 411, and the right air passage is: 1:1:8. It is to be understood that the above-described numerical ranges are illustrative only and are not limiting upon the present invention.

As shown in fig. 2 and fig. 3, the flexible gasket is sandwiched between the bottom surface of the first body 41 and the top surface of the second body 42, so as to effectively avoid gas leakage between the first body 41 and the flexible gasket, and between the second body 42 and the flexible gasket.
In some alternative embodiments, the edges of the channels of the transverse branches 461 and the longitudinal branches 462 form clamping grooves, and the rubber gasket is formed with clamping ribs which are matched with the clamping grooves. That is, the clamping ribs are embedded into the clamping grooves, so that the flexible gasket is matched with the first body 41 and the second body 42 more tightly, and the gas leakage of the gas distribution rod assembly 40 is further prevented.
