[0047] The present disclosure is further illustrated below by way of examples, but the present disclosure is not limited to the scope of the examples.

[0048] In the embodiments of the present disclosure, prefixes such as "first" and "second" are used only to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. In the embodiments of the present disclosure, the use of prefixes such as ordinal numbers to distinguish description objects does not constitute a limitation on the described objects.

[0049] Example 1

[0050] This embodiment provides a combustion control method for a combustion chamber box, which is applied to a combustion chamber box of a water heater. The combustion chamber box includes a primary air area and a secondary air area. Figure 1 , the combustion control method of the combustion chamber box includes:

[0051] S1. Obtain the initial and current outlet water temperatures of the water heater.

[0052] The time corresponding to the current outlet water temperature and the time corresponding to the initial outlet water temperature differ by a first preset time period, and the first preset time period is set according to actual conditions, for example, can be set to 5 minutes.

[0053] S2. In response to the initial outlet water temperature and the current outlet water temperature being different, obtaining a temperature difference between the initial outlet water temperature and the current outlet water temperature.

[0054] If the initial outlet water temperature and the current outlet water temperature are different, it means that the outlet water temperature is fluctuating.

[0055] S3. In response to the temperature difference being less than a preset temperature, obtaining a carbon monoxide concentration value of the water heater.

[0056] The preset temperature can be set according to actual conditions, for example, it can be set to 2 degrees Celsius.

[0057] If the temperature difference is greater than or equal to the preset temperature, it means that the user is using water, etc., and the combustion chamber box of the water heater is not in a stable combustion state. On the contrary, if the temperature difference is less than the preset temperature, it means that the combustion chamber box of the water heater is in a stable combustion state. At this time, the carbon monoxide concentration value of the water heater can represent the actual situation of the carbon monoxide concentration in the exhaust gas of the water heater.

[0058] S4. In response to the carbon monoxide concentration being greater than or equal to a preset concentration, increasing the ratio of the primary air region area to the secondary air region area to increase the primary air volume.

[0059] The preset concentration is set according to the actual situation. If the carbon monoxide concentration is greater than or equal to the preset concentration, it means that the combustion is incomplete and the amount of primary air needs to be increased.

[0060] This embodiment divides the primary air area and the secondary air area, and adjusts the range of the primary air area and the secondary air area according to the carbon monoxide concentration value, so that the carbon monoxide value of the exhaust gas of the water heater meets the preset standard, thereby improving the combustion efficiency of the water heater, reducing carbon monoxide emissions, and saving energy and reducing emissions.

[0061] In an optional embodiment, the combustion chamber box includes a carbon monoxide concentration detection device, and step S3 includes:

[0062] S31. Obtain the current value of the carbon monoxide concentration detection device.

[0063] The current value is used to represent the carbon monoxide concentration value, and the current value is positively correlated with the carbon monoxide concentration value, that is, the higher the carbon monoxide concentration, the higher the current value.

[0064] Step S4 includes:

[0065] S41 : In response to the current value being greater than or equal to a preset current value, increasing the ratio of the area of ​​the primary air region to the area of ​​the secondary air region to increase the primary air volume.

[0066] The preset current value is set according to actual conditions and corresponds to the preset concentration. In this embodiment, the preset current value is also used to represent the maximum concentration of carbon monoxide emitted by the water heater under international standards or ideal conditions.

[0067] In this embodiment, the carbon monoxide concentration is represented by the current value of the carbon monoxide concentration detection device. When the current value is greater than or equal to the preset current value, it means that the carbon monoxide concentration exceeds the preset concentration, and the air volume is increased to make the combustion in the gas chamber box more complete.

[0068] In an optional embodiment, the combustion chamber box includes an air regulating plate device, which is used to adjust the ratio of the primary air area and the secondary air area of ​​the combustion chamber box. Step S4 includes:

[0069] S42. By rotating the air regulating plate device, the ratio of the area of ​​the primary air region to the area of ​​the secondary air region is determined to be a first ratio, so as to increase the primary air volume.

[0070] In this embodiment, if Figure 2The air regulating plate device in the combustion chamber box shown can adjust its angle. The smaller the angle, the smaller the area of ​​the primary air area and the larger the area of ​​the secondary air area. That is, the smaller the angle, the greater the ratio of the area of ​​the primary air area to the area of ​​the secondary air area, so as to increase the amount of primary air, improve the completeness of combustion, and reduce carbon monoxide emissions.

[0071] In an optional embodiment, step S42 includes:

[0072] S421: Obtain an initial rotation angle of the air regulating plate device corresponding to the first ratio.

[0073] S422: Obtain the correspondence between the gear position of the air regulating plate device and the rotation angle of the air regulating plate device.

[0074] S423: Determine the first gear position of the air regulating plate device according to the corresponding relationship and the initial rotation angle of the air regulating plate device.

[0075] S424. After the second preset time period, obtain the adjusted current value of the carbon monoxide concentration detection device.

[0076] The second preset time period is set according to actual conditions. For example, the second preset time period can be set to 2 minutes.

[0077] S425. In response to the adjusted current value being greater than or equal to the preset current value, and the first gear being lower than the highest gear, the air regulating plate device is rotated according to the second gear and the corresponding relationship to adjust the ratio of the primary air area to the secondary air area to a second ratio.

[0078] Among them, the second gear is higher than the first gear, and the second ratio is greater than the first ratio, that is, the primary air volume of the second gear is greater than the primary air volume of the first gear, and the secondary air volume of the second gear is less than the secondary air volume of the first gear.

[0079] In this embodiment, the air regulating plate device has multiple gears corresponding to multiple rotation angles. As long as the current value of the carbon monoxide concentration detection device is greater than the preset current value, the gear of the air regulating plate device is increased to increase the area of ​​the primary air region and increase the primary air volume until the air regulating plate device is adjusted to the highest gear.

[0080] In an optional embodiment, step S424 includes:

[0081] S4241. In response to the adjusted current value being greater than or equal to the preset current value, but the first gear being equal to the highest gear, the air regulating plate device is maintained at the highest gear.

[0082] It should be noted that if Figure 2As shown, the highest gear of the air regulating plate device corresponds to the minimum rotation angle of the air regulating plate device (the rotation angle in this embodiment is the angle between the rotation axis of the air regulating plate device and the fixed plate 201 and the fixed axis 200 that rotate with the rotation axis). When the air regulating plate device rotates to the minimum rotation angle, it can no longer rotate, that is, the area of ​​the primary air region cannot be further increased. This is because the existence of the secondary air region must be guaranteed to prevent excessive combustion efficiency from causing excessive condensate in the water heater, affecting the durability of the internal components of the water heater. This embodiment improves combustion efficiency while controlling the generation of condensate that affects components, so that the combustion efficiency of the water heater remains within a reasonable range.

[0083] In an optional embodiment, the combustion control method of the combustion chamber box further includes:

[0084] S5. In response to the water flow of the water heater being less than the preset water flow within the third preset time period, controlling the air damper device to return to the initial gear position.

[0085] The third preset time period is set based on actual circumstances, for example, 10 minutes. The preset water flow rate includes a first water flow rate when the water heater is turned on and a second water flow rate when the water heater is turned off. The initial gear position includes the default gear position or a memorized gear position of the air damper device. The memorized gear position is the gear position when the air damper device was last turned on.

[0086] If the water flow rate of the water heater is less than the preset water flow rate within the third preset time period, it means that the water heater is in a state of just being turned on or stopped, and the combustion of the water heater is unstable or has stopped.

[0087] In an optional embodiment, the combustion control method of the combustion chamber box further includes:

[0088] S6. In response to a power outage of the water heater, the air damper device is controlled to return to an initial position.

[0089] In this embodiment, if the water flow of the water heater is less than the preset water flow within the third preset time period, or the water heater is powered off, the air regulating plate device is restored to the initial gear position.

[0090] The following introduces a specific example to explain in detail the combustion control method of the combustion chamber box of this embodiment.

[0091] Figure 3 The workflow for this example is:

[0092] S301. The water heater operates normally.

[0093] S302: Determine whether the outlet water temperature has not changed for 5 minutes (ie, whether the initial outlet water temperature is the same as the current outlet water temperature). If not, execute step S303; if so, execute step S304.

[0094] S303: Determine whether the outlet water temperature fluctuation exceeds 2 degrees Celsius (i.e., determine whether the temperature difference between the initial outlet water temperature and the current outlet water temperature is less than the preset temperature). If so, execute step S304; if not, execute step S308.

[0095] S304: The carbon monoxide concentration detection device does not work and the air regulating plate device remains stationary.

[0096] S305: Determine whether the water flow signal is lower than the start-stop flow for more than 10 minutes, or determine whether the water heater is powered off. If not, execute step S306; if so, execute step S307.

[0097] S306: The air regulating plate device remains stationary.

[0098] S307: The air regulating plate device returns to the initial gear position.

[0099] S308 , the carbon monoxide concentration detection device operates to detect the current value I of the carbon monoxide concentration detection device.

[0100] S309 , determining whether I is less than or equal to a preset current value I0; if so, returning to step S304 ; if not, executing step S310 .

[0101] S310, determining whether the angle gear of the air regulating plate device is the maximum gear, if so, returning to step S304; if not, executing step S311.

[0102] S311, the air regulating plate device is working. If there is a difference between I and I0, the angle position of the air regulating plate device is adjusted.

[0103] S312: Burn stably for 2 minutes after adjustment, and return to step S308.

[0104] See also Figure 2The structure inside the combustion chamber box includes: a rotating shaft and a fixed plate 201 that rotates with the rotating shaft, a sealing ring 202, a movable plate 203 that can slide up and down arbitrarily, an air inlet 204, and a movable bottom plate 205. The arrows represent the inlet and outlet directions of the air. The working principle of this example is: air enters the combustion chamber box from the air inlet 204, and is divided by the fixed plate 201 and the movable plate 203. A part of the air participates in the combustion and a part of the air is used as the secondary air to stabilize the flame, thus making a clear working division for the incoming air. The sealing ring 202 at the connection between the combustion chamber box and the gear shaft of the air regulating plate device ensures the sealing of the combustion system and prevents air leakage; the fixed plate 201 rotates with the rotating shaft to ensure that the size of the primary and secondary air areas can be adjusted, that is, the ratio can be controlled; the movable plate 203 moves with the fixed plate 201, so that the movable bottom plate 205 is stuck to the bottom of the combustion chamber box, ensuring that the primary and secondary air areas are clearly divided. The gear shaft of the air regulating plate device extends out and connects to a stepper motor, which controls the opening and closing of the air regulating plate device below, adjusting the air intake of the primary and secondary air ducts. This ensures that the air intake of the primary duct during stable combustion at each temperature point matches the current gas intake volume, and that the carbon monoxide value of the exhaust flue gas meets national standards or preset standards, thereby improving combustion efficiency, reducing carbon monoxide emissions, and achieving energy conservation and emission reduction. At the same time, the maximum rotation angle of the air regulating plate device is set to prevent excessive efficiency from causing the combustion system to produce excessive condensate, which would affect the durability of components. Experiments have shown that dividing the primary and secondary air areas and increasing the primary air area can significantly increase combustion efficiency and reduce carbon monoxide emissions from combustion. Thus, through a simple structure, carbon monoxide emissions can be reduced, combustion efficiency can be improved, and energy conservation and emission reduction can be achieved.

[0105] Figure 4 This is a schematic diagram of the overall structure of the air damper device in this example. The air damper device includes a gear shaft 401, an air inlet air damper 402, a fixed plate 201, a first connecting block 403, a second connecting block 404, and a movable bottom plate 205. The gear shaft 401 is welded to the second connecting block 404 and the fixed plate 201. The first connecting block 403 is welded to the air inlet air damper 402. The slider is locked to the fixed plate 201 while ensuring that the movable bottom plate 205 can slide up and down, ensuring that the bottom plate below the movable bottom plate 205 can touch the bottom of the combustion chamber box, thereby dividing the air inlet.

[0106] like Figure 5 As shown, the air regulating plate device 501 is installed at the air inlet position of the combustion chamber box 502 and is fixed by screws.

[0107] like Figure 6As shown, the lower drum platform combustion system of this example needs to ensure sealing, so a sealing ring 202 is added at the connection between the gear shaft of the combustion chamber box and the air regulating plate device to prevent air leakage. The gear shaft is extended and connected to the stepper motor, which controls the opening and closing of the lower air regulating plate to adjust the size of the primary air and secondary air flow channels.
