[0031] To make the purpose, technical scheme and advantages of the embodiments of the application clearer, the technical scheme of the application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are some but not all of the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0032] Noun explanation: fan: a fan is a machine that improves gas pressure and discharges gas by relying on input mechanical energy. It is a driven fluid machine.

[0033] Wind pressure: due to the obstruction of buildings, the surrounding air is blocked, the dynamic pressure drops, and the static pressure rises. Local vortexes are generated on the side and back, the static pressure drops, and the dynamic pressure rises. Compared with the undisturbed air flow far away, the static pressure rise and drop are collectively referred to as wind pressure.

[0034] At present, the commonly used gas water heater adjusts the fan speed through a software program, thereby adjusting the fan internal wind pressure to meet the combustion demand.

[0035] In order to facilitate understanding, Figure 1 A whole machine assembly diagram of a gas water heater is shown, and Figure 2A fan structure diagram is shown, and for the convenience of description, Figure 1 In the figure, only the gas distributor 1, the bottom shell 2 and the fan 3 of the gas water heater are shown, Figure 2 In the figure, the fan body 4, the damper blade 5, the air outlet 6 and the air inlet 7 are shown.

[0036] Based on Figure 1 The gas water heater shown, and Figure 2 The fan shown, the adjustment of the fan speed can be controlled by a software program to achieve the adjustment of the fan internal air pressure.

[0037] However, when dealing with complex environments such as highland low pressure or low temperature high pressure, the existing software adjustment of the fan speed is difficult to meet the adjustment demand of the air pressure, for example, in the plateau area, due to the low air pressure, the air is thin, and the increase of the fan speed can improve the air supply, but the greater noise brought by the fan not only brings new problems, but also shortens the service life of the fan.

[0038] Therefore, the wind pressure adjustment method, device and gas water heater provided by the embodiment of the present application can effectively alleviate the above technical problems.

[0039] In order to facilitate the understanding of the present embodiment, first, a kind of wind pressure adjustment method disclosed by the present embodiment is introduced in detail.

[0043] Further, in order to facilitate the assembly of the blade, the blade in the embodiment of the present application comprises a blade root and a fan blade; the blade root is connected with the driving mechanism; and the fan blade is used for shielding the fan damper.

[0044] In actual use, the blade root and the fan blade are usually designed in an integrated manner to form the blade, and specifically, Figure 4 The structure of the fan air pressure adjusting device is shown, and Figure 4 The fan air pressure adjusting device is shown in an exploded view, and Figure 4 The fan air pressure adjusting device is shown, and the two blades are taken as an example for illustration.

[0045] Specifically as Figure 4 shown, the fan air pressure adjusting device comprises two blades 301 and a driving motor 302, and Figure 4 The control line 303 of the driving motor is also shown, wherein the driving motor in the embodiment of the present application usually adopts a micro motor to reduce the overall volume of the fan air pressure adjusting device and avoid occupying a large space.

[0047] In actual use, the two blades in the embodiment are usually taken as a preferred embodiment, which can not only ensure the size of the inlet of the fan, but also make the driving mechanism have the simplest design, and based on the two blades, the blades are usually designed to comprise a first blade and a second blade, and as Figure 4 shown, the first blade and the second blade are symmetrically arranged; the driving mechanism also comprises a first gear and a first rotating shaft corresponding to the first blade, and a second gear and a second rotating shaft corresponding to the second blade; the first gear is connected with the driving motor, and the second gear is engaged with the first gear.

[0048] In actual use, Figure 4 the fan air pressure adjusting device shown in the figure can be formed after being assembled in the gas water heater.Figure 3 The assembly diagram is shown, and the fan air pressure adjusting device in the embodiment of the present application is fixed on the damper blade at the position of the fan damper through the driving motor.

[0049] Further, the fan air pressure adjusting device in the embodiment of the present application is further provided with a temperature sensor; as Figure 3 The temperature sensor 304 is connected with the controller of the gas water heater, used for detecting the temperature parameter of the environment where the gas water heater is located, and transmitting the temperature parameter to the controller; the controller can generate the driving signal of the driving motor according to the temperature parameter, to control the driving motor.

[0050] In the specific implementation, the temperature sensor includes a temperature probe, a probe base for fixing the temperature probe, and a pressing sheet for fixing the temperature probe; the temperature probe is arranged on the probe base; and the pressing sheet cooperates with the probe base to fix the temperature sensor on the damper blade.

[0051] In order to facilitate understanding, Figure 5 A structure diagram of a temperature sensor is shown, and Figure 5 The temperature probe 501, the probe base and the pressing sheet 503 are shown in the figure.

[0052] Further, the probe base includes a connecting column 504 and a step 505, the connecting column 504 is fixed on the step 505, and the temperature probe 501 is arranged on the connecting column 504; the step 505 is used for inserting with the preset position of the damper blade, to position the temperature sensor; and the connecting column 504 cooperates with the pressing sheet 503, to fix the temperature sensor.

[0053] Further, Figure 6 A structure diagram of a pressing sheet is also shown, as Figure 6 As shown, the pressing sheet includes a first pressing plate 601, a second pressing plate 602, and a connecting plate 603 for connecting the first pressing plate 601 and the second pressing plate 602; the end of the first pressing plate 601 is bent to one side to arrange the connecting plate 603, and the end of the connecting plate 603 away from the first pressing plate is connected with the second pressing plate; the first pressing plate is provided with an assembly opening 605, which cooperates with Figure 5 As shown, the connecting column 504; the second pressing plate 602 is provided with a fixing opening 606, which is used for fixing the pressing plate on the damper blade, to fix the temperature sensor at the preset position of the damper blade.

[0055] Furthermore, the aforementioned assembly port is generally designed as a U-shaped port, such as... Figure 5 As shown, the U-shaped opening of the pressure plate mates with the connecting post of the temperature sensor. The first pressure plate of the pressure plate presses against the mounting surface, and the fixing opening acts as a positioning hole. The step is inserted into this positioning hole for positioning. The second pressure plate and the damper plate are locked together by screws through the positioning hole, thus fixing the temperature sensor. The temperature sensor can detect temperature parameters in real time, which can be used as environmental parameters in this embodiment of the invention to adjust the air pressure of the gas water heater when implementing the air pressure adjustment method in this embodiment.

[0056] Based on the above Figures 3 to 6 The fan pressure regulating device shown can perform the pressure regulating method provided in the embodiments of the present invention.

[0057] Specifically, Figure 7 A flowchart of a wind pressure regulation method is shown, such as Figure 7 As shown, the wind pressure regulation method provided in this embodiment of the invention includes the following steps:

[0058] Step S702: In response to the start-up operation of the gas water heater, obtain the environmental parameters of the current environment in which the gas water heater is located;

[0059] This start-up operation is typically a user-activated start-up operation on the gas water heater. For example, when a user triggers the start-up control of the gas water heater, the controller of the gas water heater can respond to the start-up operation and then obtain the environmental parameters of the current environment of the gas water heater.

[0060] Step S704: Determine whether the environmental parameters meet the preset wind pressure control priority conditions;

[0061] In practical use, the wind pressure control priority condition in the embodiments of the present invention usually refers to the triggering condition for wind pressure adjustment, specifically the threshold condition that the environmental parameters meet, so that the following steps can be continued when it is determined that the environmental parameters meet the threshold condition.

[0062] Step S706: If so, calculate the opening of the fan inlet based on environmental parameters;

[0063] Step S708: Control the fan pressure regulating device according to the opening degree, so as to adjust the size of the fan inlet through the fan pressure regulating device, thereby adjusting the air pressure of the gas water heater.

[0064] The wind pressure adjusting method provided by the embodiment of the present application can respond to the starting operation acting on the gas water heater, acquire the environment parameter of the current environment of the gas water heater, and calculate the opening of the air inlet of the fan based on the environment parameter when it is judged that the environment parameter meets the pre-set wind pressure control priority condition, so as to control the fan wind pressure adjusting device according to the opening, adjust the size of the air inlet of the fan through the fan wind pressure adjusting device, and further adjust the wind pressure of the gas water heater. The adjusting method can cope with the wind pressure adjusting demand in various complex environments by adjusting the opening of the air inlet through the fan wind pressure adjusting device in structure, ensure the operation of the fan under the standard working condition, prolong the service life of the fan, ensure the operation of the fan under high efficiency, and further ensure the working efficiency of the gas water heater.

[0065] In actual use, the above-mentioned environment parameter in the embodiment of the present application includes an altitude parameter and a temperature parameter. Since the gas water heater in the embodiment of the present application is also provided with a temperature sensor, the temperature parameter included in the above-mentioned environment parameter can be obtained based on the temperature sensor. Specifically, the process of acquiring the environment parameter in the above-mentioned step S702 can include the following process:

[0066] The temperature parameter of the current environment of the gas water heater is acquired through the temperature sensor, and the altitude parameter acquisition request is sent to the pre-set altitude detection device, and the altitude parameter returned by the altitude detection device is received.

[0067] In specific implementation, after the gas water heater is started, the ambient temperature can be monitored in real time through the temperature sensor, and the ambient temperature is input to the controller as the temperature parameter. Meanwhile, the controller can communicate with the remote server, communicate with the local altitude detection device through the remote server, acquire the altitude parameter, or directly communicate with the local altitude detection device, so as to acquire the altitude parameter after starting, and further perform the subsequent wind pressure adjusting process.

[0068] Further, based on the above-mentioned altitude parameter and temperature parameter, in the above-mentioned step S704, when it is judged whether the environment parameter meets the pre-set wind pressure control priority condition, the first wind pressure control priority condition corresponding to the altitude parameter and the second wind pressure control priority condition corresponding to the temperature parameter can be acquired respectively. If the altitude parameter is higher than the altitude threshold included in the first wind pressure control priority condition, it is determined that the environment parameter meets the pre-set wind pressure control priority condition. If the altitude parameter is lower than the altitude threshold included in the first wind pressure control priority condition, it is judged whether the temperature parameter is lower than the temperature threshold included in the second wind pressure control priority condition. If the temperature parameter is lower than the temperature threshold included in the second wind pressure control priority condition, it is determined that the environment parameter meets the pre-set wind pressure control priority condition.

[0069] Based on the first wind pressure control priority condition corresponding to the altitude parameter and the second wind pressure control priority condition corresponding to the temperature parameter, a wind pressure regulation process prioritizing the altitude parameter can be realized. That is, if the altitude parameter is higher than the altitude threshold included in the first wind pressure control priority condition, it can be determined that the environmental parameter meets the preset wind pressure control priority condition. At this time, the first opening degree of the wind pressure regulating equipment can be calculated based on the altitude parameter; the first opening degree is determined as the opening degree of the air inlet of the wind fan.

[0070] If the altitude parameter is lower than the altitude threshold included in the first priority condition for wind pressure control, it means that the current altitude of the gas water heater is not in a high-altitude area. In this case, the temperature parameter is given priority. That is, if the temperature parameter is lower than the temperature threshold included in the second priority condition for wind pressure control, the second opening degree of the fan wind pressure regulating device is calculated based on the temperature parameter. Then the second opening degree is determined as the opening degree of the fan air inlet.

[0071] In specific calculations, for high-altitude areas, that is, when calculating the first opening degree of the wind turbine pressure regulating equipment based on altitude parameters, the first opening degree can be calculated according to the following formula based on the altitude parameters:

[0072] H2 = ((H-Hm) / Hm) × Hn; where H represents the altitude parameter, Hm represents the altitude threshold, and Hn represents the minimum opening unit corresponding to the altitude parameter.

[0073] When temperature parameters are given priority, the second opening degree of the fan pressure regulating equipment can be calculated using the following formula based on the temperature parameters:

[0074] T2 = ((T-Tm) / Tm) × Tn;

[0075] Where T represents the temperature parameter, Tm represents the temperature threshold, and Tn represents the minimum opening unit corresponding to the temperature parameter.

[0076] Furthermore, after calculating the opening degree of the air inlet using the above formula, when controlling the fan pressure regulating device according to the opening degree, the fan pressure regulating device can be controlled according to a certain reference time. Specifically, when determining the reference time, the fan pressure regulating device can be controlled to be in a preset reference state; then, in the reference state, the reference time when the drive motor of the blade drives the blade to rotate the blade by a preset angle is recorded; then, the fan pressure regulating device is controlled at intervals of this reference time so that the air inlet of the fan meets the above opening degree.

[0077] For example, the rotation speed of the driving motor is adjusted to the lowest state as the reference state, and the time required for the blade to rotate a preset angle, such as 5°, is taken as the reference time, and the driving motor is controlled to be turned on and off according to the reference time to drive the gear, and then the rotation shaft is driven by the gear to rotate the blade to adjust the angle of the fan damper shielded by the fan blade.

[0078] For the convenience of understanding, the working principle of the fan air pressure adjusting device is described below on the basis of the above-mentioned air pressure adjusting method. Figure 4 Figure 8 Further, a driving schematic diagram of the fan air pressure adjusting device is shown, and in addition to the structures shown in the above-mentioned air pressure adjusting method, Figure 4 Figure 8 Further, the driving direction of the blade is shown, that is, Figure 8 In the above-mentioned air pressure adjusting method, the direction of the arrow shown on the blade 301 is shown, when the driving motor rotates counterclockwise, the left gear drives the blade to rotate counterclockwise, and the right gear is engaged with the left gear, the right gear drives the blade to rotate clockwise, at this time, the blades are closed to each other, and the fan inlet is reduced; when the driving motor rotates clockwise, the left gear drives the blade to rotate clockwise, and the right gear is engaged with the left gear, the right gear drives the blade to rotate counterclockwise, at this time, the blades are opened to each other, and the fan inlet is increased. Figure 8 The angle between the two blades is shown, when the two blades are parallel, the angle is 0°. In the initial state, the angle between the two blades is 45°, in this state, the fan inlet is half open, and in the state of 90°, the fan inlet is fully open and has no shielding.

[0079] Based on the above-mentioned air pressure adjusting method of the embodiment of the present application, the working principle of the fan air pressure adjusting device is as follows:

[0080] (1) In winter, the air density is large and the noise is large under the condition of cold weather:

[0081] After the gas water heater is started, the ambient temperature can be monitored in real time by the temperature sensor, and the opening of the fan air pressure adjusting device is adjusted by the following method to control the size of the fan inlet:

[0082] For example, the preset temperature reference -10℃ is taken as the reference, and the opening size of the fan air pressure adjusting device is controlled by calculating the temperature difference; for example, in the initial state, the angle between the two blades is 45°; every 10℃, the two blades of the fan air pressure adjusting device rotate inward by 5°, that is, the angle decreases by 5°; at the same time, the rotation speed of the driving motor is adjusted to the lowest reference state, and the time required for the blade to rotate 5° is taken as the reference, and the driving motor is controlled to be turned on and off according to the time; when the temperature decreases, the controller controls the driving motor to rotate counterclockwise to control the double blades to close by 5°, that is, the angle decreases by 5°, after the blades are closed to reduce the air inlet of the fan inlet, the internal air pressure of the fan is reduced, and the overall air pressure is reduced.

[0083] (2) In the environment of high altitude area where the air is thin and the air pressure is low:​​

[0084] In the case of large noise after the gas water heater starts, the displacement distance of the pressure regulating cylinder of the fan pressure regulating device can be adjusted by the following method: taking sea level 0 m as the reference, the displacement distance of the pressure regulating cylinder of the fan pressure regulating device is calculated by the software program according to the altitude difference; if the altitude is lower than 1000 m, it is judged that the region is not a high altitude region, and the fan pressure regulating device does not need to be adjusted; if the altitude is higher than 1000 m, it is judged that the region is a high altitude region; the initial state of the two blades is 45°; within 1000 m, the fan pressure regulating device controls the double blades to rotate outward by 5° through the rotating shaft and the gear; then, the fan pressure regulating device controls the double blades to rotate outward by 5° for every 1000 m of altitude increase; when the altitude increases, the controller controls the driving motor to rotate clockwise, and controls the double blades to open by 5°, that is, the included angle increases by 5°, and the opening of the blades increases the air inlet amount, and the internal air pressure of the fan increases, and the overall air pressure increases.

[0085] Based on the above working principle, the start control logic of the fan pressure regulating device can include the following processes:

[0086] (1) If the temperature drops suddenly or in a high altitude region, the fan of the gas water heater can be adjusted to control the air pressure and adjust the noise by the following method;

[0087] First, identify whether the altitude of the region is lower than the altitude threshold included in the first air pressure control priority condition, such as 1000 m; when the altitude is greater than 1000 m, it is identified as a plateau region, and the fan pressure regulating device is adjusted; and the driving motor speed is adjusted to the lowest reference state, and the time required for the blade to rotate by a preset angle, such as 5°, is taken as the reference, and the on-off time of the driving motor is controlled based on this time.

[0088] Taking 1000 m as the altitude threshold, the extension amount of the opening at this time conforms to the formula: total extension amount (H0) = extension amount within 1000 m (H1) + extension amount above 1000 m (H2).

[0089] The double blades in the fan pressure regulating device within 1000 m open outward by 5°, that is, H1 = +5°.

[0090] Above 1000 m, for every 1000 m increase, open outward by 5°, that is, H2 = ((total altitude-1000) / 1000) x 5°, where (total altitude-1000) / 1000 is an integer, and if it is less than 500, it is automatically taken as 1.

[0094] If the weather is higher than-10℃, that is, it is not a low-temperature environment, the fan wind pressure adjusting device is not started; if the weather is lower than-10℃, it is determined that it is a low-temperature environment, and the fan wind pressure adjusting device is ready to start.

[0095] At this time, the environment temperature T can be set to decrease by 10℃, and the fan wind pressure adjusting device is closed by 5° inward, that is, -5°; the expansion and contraction amount of the opening degree can be expressed as T2=((T-10)÷10)×5°, wherein (T-10)÷10 is an integer, and 1 is taken if it is less than 10.

[0096] Similarly, the driving motor drives the gear and the double-blade to close; the double-blade is adjusted to a specified angle; the driving motor stops rotating; at this time, the gas water heater is ignited and burned.
