Description

Technical Field

[0001] This application relates to the field of gas appliance technology, and in particular to a diversion device and a gas water heater. Background Technology

[0002] During the use of gas water heaters, they operate at different loads depending on the usage conditions. In related technologies, because gas water heaters have a single air inlet structure, they cannot adapt to different combustion loads of the burner, leading to poor combustion performance. Summary of the Invention

[0003] Therefore, it is necessary to provide a diversion device and a gas water heater that can adjust the air intake according to the different combustion loads of the burner to adapt to the working state of the burner, thereby avoiding poor combustion conditions.

[0004] According to one aspect of this application, an embodiment of this application provides a flow-diverting device for providing diverted air to a segmented burner in a gas water heater; the flow-diverting device includes:

[0005] The diversion body has a gas collection chamber inside it;

[0006] An air inlet is located at the bottom of the distribution body and is connected to the air collection chamber;

[0007] Multiple air outlets are located at the top of the diversion body and are all connected to the air collection chamber to form multiple air ducts through which fluid can flow in from the air inlet and out from the multiple air outlets; and

[0008] Multiple adjusting components, each of which corresponds to one of the air ducts and is used to open or close the corresponding air duct;

[0009] The multiple air outlets are respectively located in different sections of the segmented burner.

[0010] The aforementioned air diversion device includes at least a diversion body, an air inlet, multiple air outlets, and multiple regulating components. By setting up the air inlet and multiple air outlets, multiple air ducts are formed, and the multiple air outlets are respectively directed to different sections of the segmented burner, ensuring that each section of the segmented burner has a corresponding air duct to supply the air required for combustion. Simultaneously, since each air duct is equipped with a regulating component, which can open or close the air duct, the corresponding air duct can be opened according to the different combustion loads of the segmented burner, achieving air intake within the corresponding section of the segmented burner. Therefore, the air intake in the gas water heater can adapt to the operating state of the segmented burner, thereby avoiding problems with poor combustion conditions.

[0011] In one embodiment, the diversion body is further provided with at least one diversion cavity located on the top side of the gas collection cavity and independent of the gas collection cavity, and ventilation openings corresponding to the diversion cavities.

[0012] The flow divider chamber is connected to the gas collection chamber via a corresponding vent, and an air outlet is formed on the wall of the flow divider chamber, so that at least one of the plurality of air ducts can be a duct structure in which fluid flows in from the air inlet, passes through the vent, and flows out from the corresponding air outlet. Thus, by providing the flow divider chamber, it is convenient to align the corresponding air outlet with the corresponding section of the segmented burner.

[0013] In one embodiment, the shunt body includes:

[0014] A bottom shell, on which the air inlet is provided;

[0015] A cover plate, which is disposed on the bottom shell and encloses and defines the gas collecting cavity; and

[0016] At least one guide vane, the guide vane being disposed on the cover plate and enclosing and defining the flow-dividing cavity having a first opening;

[0017] Wherein, at least one of the plurality of air outlets is formed by at least one of the first openings in a one-to-one correspondence; the remaining air outlets and the ventilation openings are disposed on the cover plate;

[0018] The remaining air outlets of the plurality of air outlets are located outside the orthogonal projection of the guide plate on the cover plate; the vents are located within the orthogonal projection of the guide plate on the cover plate. Thus, by configuring the flow distribution body into a structure including a bottom shell, a cover plate, and a guide plate, the desired air collection chamber and flow distribution chamber are obtained.

[0019] In one embodiment, at least one of the cover plate and the guide plate is provided with a recessed portion that is recessed toward the direction away from the other;

[0020] The guide plate is placed on the cover plate and, with the aid of the recess, forms the flow-dividing cavity having the first opening. Thus, the desired flow-dividing cavity can be formed by providing the recess.

[0021] In one embodiment, the bottom shell includes a bottom wall and a side wall surrounding the bottom wall, the bottom wall and the side wall forming a receiving cavity with a second opening at one end, and the air inlet is provided on the bottom wall;

[0022] The cover plate is placed over the second opening and, with the help of the receiving cavity, forms the gas collecting chamber. Thus, the required gas collecting chamber can be formed through the bottom shell.

[0023] In one embodiment, in one of the plurality of air ducts that includes the vent, the adjusting member is used to open or close the vent; and / or

[0024] In the plurality of air ducts, excluding the duct containing the vent, the adjusting member is used to open or close the air outlet corresponding to the remaining air duct. Thus, by using the adjusting member to open or close the vent or air outlet, the corresponding air duct can be opened or blocked to adapt to different combustion loads and maintain optimal combustion conditions for the water heater.

[0025] In one embodiment, the remaining air ducts among the plurality of air ducts, excluding the air duct containing the vent, are provided with one;

[0026] The air outlets corresponding to the remaining air ducts are all located on the same side of the cover plate as the ventilation openings. Thus, only one air outlet communicates with the air collection chamber, while the others communicate with the distribution chambers. Placing this single air outlet and the ventilation openings on the same side of the cover plate facilitates the placement of adjustment components on the same side to open or close the ventilation openings and air outlets. This reduces the overall space occupied by the device.

[0027] In one embodiment, the diversion body further includes a first seal disposed between the cover plate and the guide plate, the connection between the cover plate and the guide plate being sealed by means of the first seal; and / or

[0028] The diversion body also includes a second sealing element disposed between the cover plate and the bottom shell, and the connection between the cover plate and the bottom shell is sealed by means of the second sealing element. Thus, by providing the first sealing element and / or the second sealing element, the sealing performance at the corresponding connection portion can be improved, preventing air leakage.

[0029] In one embodiment, the cover plate and the deflector plate are detachably connected; and / or

[0030] The cover plate and the bottom shell are detachably connected. This facilitates the disassembly and maintenance of the entire device.

[0031] In one embodiment, the regulating element includes a solenoid valve, and the bottom wall of the diversion body is provided with a through hole;

[0032] The solenoid valve is installed at the through hole, and its stem is located in the air collection chamber and is used to open or close the corresponding vent or outlet in the air duct. Thus, the solenoid valve can be used to open or close the corresponding air duct.

[0033] According to another aspect of this application, an embodiment of this application provides a gas water heater, characterized by including the diversion device as described above. Thus, by setting an air inlet and multiple air outlets in the diversion device to form multiple air ducts, and distributing the multiple air outlets to different sections of a segmented burner, each section of the segmented burner has a corresponding air duct to provide the air required for combustion. Simultaneously, since each air duct is equipped with an adjusting element that can open or close the air duct, the corresponding air duct can be opened according to the different combustion loads of the segmented burner, achieving air intake within the corresponding section of the segmented burner. Therefore, the air intake within the gas water heater can adapt to the operating state of the segmented burner, thereby avoiding the problem of poor combustion conditions.

[0068] Figure 1A schematic diagram of a gas water heater in one embodiment of the related technology is shown; for ease of explanation, only the parts related to the embodiment of the related technology are shown.

[0069] Please refer to Figure 1 One embodiment of the related technology provides a gas water heater, which includes a burner assembly 1, a fan assembly 2, a heat exchanger assembly 3, and a fume hood assembly 4. An opening is provided on the bottom plate of the burner assembly 1's casing, through which the fan assembly 2 supplies the combustion air required for combustion to the combustion chamber within the burner assembly 1. When the gas water heater is operating, the fan assembly 2 starts to supply air, which passes through the burner assembly 1 and the heat exchanger assembly 3, and is then discharged from the exhaust port of the fume hood assembly 4.

[0070] The inventors of this application have noticed that during this process, the gas water heater operates at different loads depending on the usage conditions. Because the bottom plate of the burner assembly 1 has an opening, forming a single air inlet structure, it cannot adapt to different combustion loads within the burner assembly 1, leading to poor combustion conditions. More specifically, on the one hand, when the gas water heater operates at its maximum load, the single air inlet structure causes the flame near the air inlet to be too high, and in extreme cases, flame detachment occurs; the flame away from the air inlet is too low, resulting in insufficient primary air and high flue gas levels. On the other hand, when the gas water heater operates at its minimum load, due to structural limitations, the smallest section of the burner is far from the air inlet side, causing air to escape near the air inlet, resulting in a denser flame and higher flue gas levels.

[0071] Based on this, the inventors of this application, through in-depth research, have developed a method to adapt to different combustion loads of the burner within the burner assembly 1 by changing the air intake method and combining it with a flow diversion device. The flow diversion device provided in the embodiments of this application will be described below with reference to some examples.

[0072] Figure 2 A schematic diagram of the structure of a gas water heater according to one embodiment of this application is shown; Figure 3 A schematic diagram of the burner assembly 1 in one embodiment of this application is shown; Figure 4 A schematic diagram of the structure of the diversion device 11 in one embodiment of this application is shown; Figure 5 A partial exploded structural diagram of the diversion device 11 in one embodiment of this application is shown; for ease of explanation, only the parts related to the embodiment of this application are shown.

[0073] Please refer to Figure 2 and Figure 3In some embodiments, the diversion device 11 provided in this application is used in a gas water heater. The gas water heater includes a burner assembly 1, a fan assembly 2, a heat exchanger assembly 3, and a smoke hood assembly 4. The burner assembly 1 includes the diversion device 11, a segmented burner 12, and a combustion chamber enclosure 13. The diversion device 11 is located at the bottom of the combustion chamber enclosure 13 and forms a combustion chamber with the enclosure 13; the segmented burner 12 is located within the combustion chamber. The output port of the fan assembly 2 is connected to the air inlet 200 on the diversion device 11. The diversion device 11 provides diverted air to the segmented burner 12 within the gas water heater. When the gas water heater is operating, the fan assembly 2 starts to supply air, which passes through the diversion device 11, the segmented burner 12, the heat exchanger assembly 3, and is then discharged from the exhaust port of the smoke hood assembly 4.

[0074] Please refer to Figure 4 and Figure 5 In some embodiments, the diversion device 11 includes a diversion body 100, an air inlet 200, multiple air outlets 300, and multiple adjusting components 400. The diversion body 100 has an air collection chamber a (which can be referred to in conjunction with the diagram shown below). Figure 9 and Figure 10 An air inlet 200 is located at the bottom of the distribution body 100 and is connected to the gas collection chamber a. Multiple air outlets 300 are located at the top of the distribution body 100 and are all connected to the gas collection chamber a, forming multiple air ducts through which fluid can flow in from the air inlet 200 and out from the multiple air outlets 300. Each adjusting member 400 corresponds to one air duct and is used to open or close the corresponding air duct. The multiple air outlets 300 correspond to different sections of the segmented burner 12. That is, the number of air outlets 300 corresponds one-to-one with the number of sections of the segmented burner 12, and different air outlets 300 form different air ducts. The number of adjusting members 400 corresponds one-to-one with the number of air ducts. Figure 2 and Figure 4 For example, the illustration shows a segmented burner 12 divided into two sections, with two air outlets 300 forming two air ducts, and two adjusting members 400. This application embodiment does not impose specific limitations on the number of air outlets 300 or the number of sections of the segmented burner 12.

[0075] It should be noted that multiple adjusting components 400 can simultaneously open or close the corresponding air ducts, or some air ducts can be open while others are blocked. The opening or blocking of the corresponding air ducts can be achieved according to the working state of the segmented burner 12, and this embodiment does not impose specific limitations on this.

[0076] Therefore, by setting up an air inlet 200 and multiple air outlets 300, multiple air ducts are formed, and the multiple air outlets 300 are respectively located in different sections of the segmented burner 12, so that each section of the segmented burner 12 has a corresponding air duct to provide the air required for combustion. At the same time, since each air duct is equipped with an adjusting component 400, the adjusting component 400 can open or close the air duct, so that the corresponding air duct can be opened according to the different combustion loads of the segmented burner 12, realizing the air intake in the corresponding section of the segmented burner 12. In this way, the air intake in the gas water heater can adapt to the working state of the segmented burner 12, thereby avoiding the problem of poor combustion conditions.

[0077] To facilitate aligning the corresponding air outlets 300 with the corresponding sections of the segmented burner 12, in some embodiments, please refer to... Figure 4 and Figure 5 (and can be combined with the following illustrations) Figure 9 and Figure 10 The diversion body 100 also includes at least one diversion cavity b located on the top side of the air collection cavity a and independent of the air collection cavity a, and a ventilation opening 500 corresponding to each diversion cavity b. The diversion cavity b is connected to the air collection cavity a via its corresponding ventilation opening 500, and an air outlet 300 is formed on the wall of the diversion cavity b, so that at least one of the multiple air ducts is a duct structure in which fluid can flow in from the air inlet 200, pass through the ventilation opening 500, and flow out from the corresponding air outlet 300. That is to say, among the multiple air outlets 300, some air outlets 300 are connected to the air collection cavity a, and some air outlets 300 are connected to the corresponding diversion cavity b. The fluid coming out of the air outlet 300, which is connected to the corresponding diversion chamber b, will first flow into the air collection chamber a from the air inlet 200, then flow into the diversion chamber b through the corresponding vent 500 from the air collection chamber a, and finally flow out from the diversion chamber b through the air outlet 300.

[0078] During this process, a portion of the fluid can be diverted from the gas collecting chamber a through the diversion chamber b and transported to the corresponding section of the segmented burner 12. The fluid that has passed through the diversion chamber b is more stable than the fluid that flows directly out of the gas collecting chamber a through the corresponding air outlet 300. Thus, by setting up the diversion chamber b, not only is it easier to set up the corresponding air outlet 300, but the combustion process can also be made more stable.

[0079] Please continue to refer to Figure 4 and Figure 5In some embodiments, the diversion body 100 includes a bottom shell 110, a cover plate 120, and at least one guide plate 130. The bottom shell 110 has an air inlet 200. The cover plate 120 covers the bottom shell 110 and encloses and defines an air collection cavity a. The guide plate 130 covers the cover plate 120 and encloses and defines a diversion cavity b having a first opening b1. At least one of the plurality of air outlets 300 is formed by a corresponding first opening b1, and the remaining air outlets 300 and a vent 500 are disposed on the cover plate 120. The remaining air outlets 300 are located outside the orthographic projection of the guide plate 130 onto the cover plate 120. The vent 500 is located within the orthographic projection of the guide plate 130 onto the cover plate 120. In other words, the number of guide vanes 130, the number of vents 500, and the number of flow dividers b are all the same and correspond one-to-one. Figure 4 and Figure 5 For example, a flow guide plate 130 is provided, forming a flow divider cavity b. There are two air outlets 300, one located on the cover plate 120 and the other formed by the first opening b1 of the flow divider cavity b. There is one vent 500, located on the cover plate 120 and connected to the flow divider cavity b. Thus, by configuring the flow divider body 100 with a structure including the bottom shell 110, the cover plate 120, and the flow guide plate 130, the desired air collection cavity a and flow divider cavity b are obtained.

[0080] Please continue to refer to Figure 4 and Figure 5 Specifically, in some embodiments, at least one of the cover plate 120 and the guide plate 130 has a recessed portion that is recessed away from the other. The guide plate 130 is disposed on the cover plate 120 and forms a flow-diverting cavity b with a first opening b1 by means of the recessed portion. (The following is illustrated...) Figure 7 and Figure 8 For example, the illustration shows a case where both the cover plate 120 and the guide plate 130 have recessed portions. The cover plate 120 has a first recessed portion 121 recessed in a direction away from the guide plate 130, and the guide plate 130 has a second recessed portion 131 recessed in a direction away from the cover plate 120. The first recessed portion 121 and the second recessed portion 131 together define a flow-dividing cavity b having a first opening b1. Of course, it is also possible to have recessed portions only on the cover plate 120 or only on the guide plate 130, depending on the usage requirements. This application embodiment does not impose specific limitations on this. The first opening b1 can be formed on the side of the flow-dividing cavity b or on the top of the flow-dividing cavity b. For example, Figure 4 and Figure 5 The illustration shows the case where a first opening b1 is formed on the side of the diversion cavity b, and this first opening b1 is an air outlet 300 connected to the diversion cavity b. In this way, the desired diversion cavity b can be formed by providing a recess.

[0081] Figure 6 A schematic diagram of the bottom shell 110 in one embodiment of this application is shown; Figure 7 A schematic diagram of the cover plate 120 in one embodiment of this application is shown; for ease of explanation, only the parts related to the embodiment of this application are shown.

[0082] Please refer to Figure 6 and Figure 7 and in conjunction with reference Figure 4 and Figure 5 In some embodiments, the bottom shell 110 includes a bottom wall 111 and a side wall 112 surrounding the bottom wall 111. The bottom wall 111 and the side wall 112 form a receiving cavity c with a second opening c1 at one end. An air inlet 200 is provided on the bottom wall 111. A cover plate 120 is placed over the second opening c1 and forms an air collecting cavity a by means of the receiving cavity c. In this way, the required air collecting cavity a can be formed by the bottom shell 110. Of course, in other embodiments, the bottom shell 110 can also be set in a plate shape, and the cover plate 120 can be set in a shell shape with a receiving cavity c. The two can be fitted together to form the required structure. The choice can be made according to the actual use requirements, and the embodiments of this application do not impose specific limitations on this.

[0083] Please continue to refer to Figure 4 and Figure 5 In some embodiments, in a duct containing a vent 500 among multiple air ducts, the adjusting member 400 is used to open or close the vent 500. In other embodiments, in the remaining air ducts among multiple air ducts other than the one containing the vent 500, the adjusting member 400 is used to open or close the air outlet 300 corresponding to the remaining air duct. Thus, by using the adjusting member 400 to open or close the vent 500 or the air outlet 300, the corresponding air duct can be opened or blocked to adapt to different ventilation conditions under different combustion loads, so that the water heater maintains optimal combustion conditions. In other specific embodiments, the adjusting member 400 can also be used to open or block the corresponding air duct, that is, to divide the cavity into different cavities in the diversion cavity b and / or the gas collection cavity a. For example, taking the gas collection cavity a as an example, the adjusting member 400 can divide the gas collection cavity a into two cavities, one cavity connected to the air inlet 200 and the other cavity connected to the vent 500. The adjustment method of the metric adjustment component 400 can be selected according to the actual usage situation, and this application embodiment does not impose specific restrictions on this.

[0084] Please continue to refer to Figure 4 and Figure 5Specifically, in some embodiments, one of the multiple air ducts is provided, excluding the one containing the vent 500. The corresponding air outlet 300 of this remaining air duct is located on the same side of the cover plate 120 as the vent 500. Thus, only one air outlet 300 communicates with the air collection chamber a, while the other air outlets 300 communicate with the diversion chamber b. In this case, placing the one air outlet 300 and the vent 500 on the same side of the cover plate 120 facilitates the placement of the adjusting member 400 on the same side to open or close the vent 500 and the air outlet 300. This reduces the space occupied by the overall device. Figure 2 , Figure 4 and Figure 5 For example, an air outlet 300 and a vent 500 can be located on the right side of the cover plate 120, and the fan assembly 2 can be located on the left side of the bottom of the diversion device 11. In this case, the adjusting components 400 can be located on the right side of the bottom of the diversion device 11. In this way, the space of the gas water heater can be effectively utilized, thereby reducing the space occupied by the overall device.

[0085] To improve the sealing performance of the diversion device 11 and prevent air leakage, please refer to... Figure 5 In some embodiments, the diversion body 100 further includes a first sealing member 600 disposed between the cover plate 120 and the guide plate 130, and the connection between the cover plate 120 and the guide plate 130 is sealed by means of the first sealing member 600. Specifically, in some embodiments, referring to the foregoing embodiments, the periphery of the first recess 121 on the cover plate 120 is provided with a plurality of first protrusions 122, and the first sealing member 600 is fixed on the periphery of the first recess 121 by the first protrusions 122, which can prevent the second sealing member 700 from tilting. Please continue to refer to Figure 5 In other embodiments, the diversion body 100 further includes a second sealing member 700 disposed between the cover plate 120 and the bottom shell 110, and the connection between the cover plate 120 and the bottom shell 110 is sealed by means of the second sealing member 700. Specifically, in some embodiments, referring to the foregoing embodiments, a flange structure can be formed outward on the side wall 112 of the bottom shell 110, and a plurality of second protrusions 113 are provided on the flange structure. The second sealing member 700 is fixed to the flange structure of the side wall 112 of the bottom shell 110 through the second protrusions 113, which can prevent the second sealing member 700 from tilting.

[0086] Figure 8 A schematic diagram of the structure of the guide plate 130 in one embodiment of this application is shown; for ease of explanation, only the parts related to the embodiment of this application are shown.

[0087] To facilitate the disassembly and maintenance of the overall device, please refer to the following in some embodiments: Figure 8 and in conjunction with reference Figure 4 , Figure 5 and Figure 7 The cover plate 120 and the deflector plate 130 are detachably connected. Optionally, the cover plate 120 and the deflector plate 130 can be detachably connected together by bolts. In other embodiments, please continue to refer to... Figures 4 to 7 The cover plate 120 and the bottom shell 110 are detachably connected. Alternatively, the cover plate 120 and the bottom shell 110 can be detachably connected together by bolts.

[0088] Please continue to refer to Figure 4 and Figure 5 In some embodiments, the regulating element 400 includes a solenoid valve. The bottom wall of the diversion body 100 has a through hole 800. The solenoid valve is installed in the through hole 800, and its stem is located within the air collection chamber a and is used to open or close the corresponding vent 500 or outlet 300 in the air duct. Specifically, with... Figure 4 and Figure 5 For example, two through holes 800 can be provided on the bottom wall 111 of the bottom shell 110, one of which is connected to... Figure 5 One of the vents, 500, corresponds to the other through-hole, 800. Figure 5 The ventilation opening 500 on the right side corresponds to this. Two solenoid valves correspond one-to-one with two through holes 800, extending into the corresponding through holes 800. The opening and closing of the corresponding ventilation opening 500 and the corresponding air outlet 300 are achieved by the action of the solenoid valve's lever. Optionally, a sealing gasket (not shown in the figure) can be used at the connection between the solenoid valve and the through hole to further improve the sealing. Thus, the solenoid valve can be used to open or close the corresponding air duct. Of course, in other embodiments, the adjusting member 400 can also be other electric or pneumatic mechanical devices; this application does not impose specific limitations on this.

[0089] Figure 9 The diagram shows a cross-sectional view of the diversion device 11 in one perspective according to an embodiment of this application;

[0090] Figure 10 The diagram shows a cross-sectional view of the diversion device 11 from another perspective in one embodiment of this application.

[0091] The following is combined Figure 9 , Figure 10 In addition to the relevant content in some of the above embodiments, taking the example of a segmented burner 12 having two sections, a flow divider b having one section, a vent 500 having one section, an air outlet 300 having two sections, and an adjusting member 400 having two sections, the working process of the flow divider device 11 provided in the embodiments of this application will be further explained.

[0092] When only fluid is needed to flow from the air outlet 300 on the cover, the air outlet 300 on the cover is opened via the corresponding adjusting member 400, and the air vent 500 on the cover is closed via the corresponding adjusting member 400. For example... Figure 9 As shown, fluid enters the air collection chamber a from the air inlet 200 and flows out from the air outlet 300 on the cover. When only fluid needs to flow out from the air outlet 300 on the diversion chamber b, the vent 500 on the cover is opened by the corresponding adjusting member 400, and the air outlet 300 on the cover is closed by the corresponding adjusting member 400. Figure 10 As shown, fluid enters the air collection chamber a from the air inlet 200, flows into the distribution chamber b through the vent 500 on the cover, and then flows out from the air outlet 300 on the distribution chamber b. When fluid needs to flow out from both the air outlet 300 on the cover and the air outlet 300 on the distribution chamber b, the air outlet 300 on the cover is opened via the corresponding adjusting component 400, and the vent 500 on the cover is also opened via the corresponding adjusting component 400. After entering the air collection chamber a from the air inlet 200, the fluid is divided into two paths. One path flows out from the air outlet 300 on the cover, and the other path flows into the distribution chamber b through the vent 500 on the cover, and then flows out from the air outlet 300 on the distribution chamber b.

[0093] Based on the same inventive concept, please refer to Figure 2 and Figure 3 This application provides a gas water heater, including the diversion device 11 described in the above embodiment. By setting an air inlet 200 and multiple air outlets 300 in the diversion device 11 to form multiple air ducts, and distributing the multiple air outlets 300 to different sections of the segmented burner 12, each section of the segmented burner 12 has a corresponding air duct to provide the air required for combustion. Simultaneously, since each air duct is equipped with an adjusting element 400, which can open or close the air duct, the corresponding air duct can be opened according to the different combustion loads of the segmented burner 12, achieving air intake within the corresponding section of the segmented burner 12. Therefore, the air intake in the gas water heater can adapt to the working state of the segmented burner 12, thereby avoiding the problem of poor combustion conditions.

[0094] In summary, the diversion device 11 provided in this application embodiment allows each section of the burner 12 to have a corresponding air outlet 300 at its bottom when the gas water heater is burning at maximum load. This is beneficial for flame uniformity, complete combustion of the gas, and improving the primary air coefficient, thus improving flue gas quality. When the gas water heater is burning at minimum load, the corresponding air outlet 300 under each combustion section can be switched on or off according to the actual segmentation, which improves air utilization, ensures complete combustion of the gas, and improves flue gas quality. Therefore, the air intake within the gas water heater can adapt to the operating state of the section burner 12, thereby avoiding problems with poor combustion conditions.

[0095] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0096] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
