Description

Technical Field

[0001] This invention relates to the field of gas water heater technology, and in particular to a method for regulating air pressure. Background Technology

[0002] Gas water heaters are generally equipped with a fan. When the fan is started, it blows oxygen into the combustion chamber to make combustion more complete.

[0003] In high-altitude areas, due to the high altitude, low air pressure, and thin oxygen, gas water heaters require more air for combustion. In such cases, the only solution is to control the fan through a program to increase its speed and improve air supply. However, this causes the fan's electrode temperature to rise, reducing its output power. Furthermore, with prolonged use, it becomes difficult to achieve the air pressure and airflow specified on the fan's nameplate, shortening its lifespan. In addition, the fan will generate more noise, affecting the user experience and reducing user satisfaction. Summary of the Invention

[0004] The purpose of this invention is to provide a wind pressure regulation method to alleviate the technical problems in the prior art where the lifespan of the fan of a gas water heater is affected and the fan generates greater noise when applied in high-altitude areas.

[0005] To solve the above-mentioned technical problems, the technical means adopted by the present invention are as follows:

[0006] The wind pressure regulation method provided by this invention includes the following steps:

[0007] Power on: Gas water heater starts;

[0008] Information recognition: The information recognition module identifies the local altitude and temperature;

[0009] Wind pressure regulation: The main controller receives environmental information transmitted from the information recognition module, and after discrimination and calculation, controls the drive component to start, so as to drive the pressure regulating cylinder installed in the air inlet of the fan to move a preset distance, so that the length of the pressure regulating cylinder inside the fan changes accordingly.

[0010] Power off: The power is cut off after the drive component drives the pressure regulating cylinder to a preset point.

[0011] Furthermore, in the wind pressure regulation step, if the altitude is not higher than 1000m and the temperature is not lower than 10℃, the main controller determines that it is a non-high-altitude and non-low-temperature area, and the drive component does not start.

[0012] If the altitude is not higher than 1000m and the temperature is lower than 10℃, the main controller determines that it is a non-high-altitude low-temperature area and controls the drive component to start after calculation;

[0013] If the altitude is higher than 1000m, the main controller determines that it is a plateau region and controls the drive component to start after calculation.

[0014] Furthermore, when the altitude is not higher than 1000m and the temperature is not lower than 10℃, the length of the pressure regulating cylinder extending outside the fan is 2mm.

[0015] Furthermore, when the altitude is not higher than 1000m and the temperature T is lower than 10℃, the length of the pressure regulating cylinder extending outside the fan is L1;

[0016] Where L1 = 2 mm - (10℃ - T) / 5℃ × 2 mm, and the value of (10℃ - T) / 5℃ is rounded up.

[0017] Furthermore, when the altitude H > 1000m, the length of the pressure regulating cylinder extending outside the fan is L2;

[0018] Where L2 = (H-1000m) / 500m × 2 mm + 2 mm, and the value of (H-1000m) / 500m is rounded up.

[0019] Furthermore, the information recognition module includes a temperature sensor;

[0020] The temperature sensor is used to read the local temperature and transmit the temperature information to the main controller.

[0021] Furthermore, the information identification module also includes a WIFI module;

[0022] The WIFI module is used to connect to the network to read the local altitude and transmit the altitude information to the main controller.

[0023] Furthermore, the drive assembly includes a stepper motor and a ball screw;

[0024] The output end of the stepper motor is connected to the ball screw, and the ball screw is connected to the pressure regulating cylinder.

[0025] Furthermore, the air pressure adjustment step is completed before the water flow rate reaches the specified speed.

[0026] Furthermore, the following steps are included after the power-off step;

[0027] Fan start-up;

[0028] Ignition and combustion.

[0029] Compared with existing technologies, the wind pressure regulation method provided by this invention has the following technical advantages:

[0030] The wind pressure regulation method provided by this invention includes the following steps: Power on: The gas water heater is started; Information recognition: The information recognition module recognizes local environmental information such as altitude and temperature; Wind pressure regulation: The main controller receives the environmental information transmitted from the information recognition module, and after discrimination and calculation, controls the drive component to start, so as to drive the pressure regulating cylinder installed in the air inlet of the fan to move a preset distance, so that the length of the pressure regulating cylinder in the fan changes accordingly; Power off: The drive component drives the pressure regulating cylinder to move to the preset point and then the power is cut off.

[0031] In the air pressure regulation process, the pressure regulating cylinder has two states: extending in and extending out. Specifically, when the pressure regulating cylinder extends from the air inlet into the fan, the internal resistance of the fan increases, the pressure loss increases, and the overall air pressure of the fan decreases. When the pressure regulating cylinder extends from the air inlet out of the fan, the internal resistance of the fan decreases, the pressure loss decreases, and the overall air pressure of the fan increases. It can be seen that the former situation can reduce the air pressure without changing the fan speed, thus improving the problem of high fan noise caused by cold weather and high air density in winter. The latter situation can increase the air pressure without changing the fan speed, thereby increasing the air supply to meet the combustion requirements of the combustion chamber without increasing the fan speed. This extends the lifespan of the fan in gas water heaters used in high-altitude areas and avoids the problem of increased noise caused by increasing the speed. Therefore, this air pressure regulation method allows gas water heaters to be used in different environments and ensures that the fan operates near standard conditions. Attached Figure Description

[0043] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] refer to Figure 1 The wind pressure regulation method provided in this embodiment includes the following steps: Power on: The gas water heater is started; Information recognition: The information recognition module recognizes local environmental information such as altitude and temperature; Wind pressure regulation: The main controller 100 receives the environmental information transmitted from the information recognition module, and after discrimination and calculation, controls the drive component 200 to start, so as to drive the pressure regulating cylinder 400 passing through the air inlet 310 of the fan 300 to move a preset distance, so that the length of the pressure regulating cylinder 400 inside the fan 300 changes accordingly; Power off: The drive component 200 drives the pressure regulating cylinder 400 to move to the preset point and then the power is off; The fan 300 is started; Ignition and combustion.

[0047] In the air pressure adjustment process, the pressure regulating cylinder 400 has two states: extending and extending. Specifically, when the pressure regulating cylinder 400 extends into the fan 300 from the air inlet 310, the internal resistance of the fan 300 increases, the pressure loss increases, and the overall air pressure of the fan 300 decreases. When the pressure regulating cylinder 400 extends outward from the air inlet 310, the internal resistance of the fan 300 decreases, the pressure loss decreases, and the overall air pressure of the fan 300 increases. It can be seen that the former situation reduces air pressure without changing the fan 300's rotational speed, thus improving the problem of high fan noise caused by cold weather and high air density in winter. The latter situation increases air pressure without changing the fan 300's rotational speed, thereby increasing the air supply to meet the combustion requirements of the combustion chamber without increasing the fan 300's rotational speed. Therefore, for gas water heaters used in high-altitude areas, the lifespan of the fan 300 will be extended, while also avoiding the problem of increased noise caused by increasing the rotational speed. Therefore, this wind pressure regulation method enables gas water heaters to be suitable for different environments and ensures that the fan 300 operates under near-standard conditions.

[0048] It should be added that the air pressure adjustment step is completed before the water flow rate and rotation speed reach the specified speed.

[0049] Furthermore, in addition to the two cases of extension and retraction, the pressure regulating cylinder 400 also includes a stationary case.

[0050] Specifically, when the altitude is no higher than 1000m and the temperature is no lower than 10℃, the main controller 100 determines that it is a non-high-altitude, non-low-temperature region, and the drive component 200 does not start, thus keeping the pressure regulating cylinder 400 stationary. In this state, the length of the pressure regulating cylinder 400 extending beyond the fan 300 is 2mm. When the altitude is no higher than 1000m and the temperature is lower than 10℃, the main controller 100 determines that it is a non-high-altitude, low-temperature region, and after calculation, controls the drive component 200 to start, driving the pressure regulating cylinder 400. The pressure regulating cylinder 400 extends into the fan 300 by a preset distance, reducing the internal air pressure of the fan 300 and meeting the requirements for use of the fan 300 in cold winter weather. When the altitude is higher than 1000m, the main controller 100 determines that it is a high-altitude area and, after calculation, controls the drive component 200 to start, driving the pressure regulating cylinder 400 to move a preset distance, so that the pressure regulating cylinder 400 extends outward from the fan 300, increasing the internal air pressure of the fan 300 and meeting the requirements for use of the fan 300 in high-altitude areas.

[0051] Furthermore, when the altitude is not higher than 1000m and the temperature T is lower than 10℃, the length of the pressure regulating cylinder 400 extending outside the fan 300 is L1; where L1 = 2mm - (10℃ - T) / 5℃ × 2mm, and the value of (10℃ - T) / 5℃ is rounded up.

[0052] Specifically, when T is 0℃, L1 = 2mm - (10℃ - 0℃) / 5℃ × 2mm = -2mm, meaning the pressure regulating cylinder 400 is inside the fan 300 and 2mm away from the air inlet 310, resulting in a pressure drop of 40Pa. When T is -2.5℃, L1 = 2mm - (10℃ + 2.5℃) / 5℃ × 2mm = -4mm, meaning the pressure regulating cylinder 400 is inside the fan 300 and 4mm away from the air inlet 310. By adjusting the pressure regulating cylinder 400, the fan 300 generates less noise when used in non-high-altitude, low-temperature environments.

[0053] Furthermore, when the altitude H > 1000m, the length of the pressure regulating cylinder 400 extending outside the fan 300 is L2; ​​where L2 = (H-1000m) / 500m × 2mm + 2mm, and the value of (H-1000m) / 500m is rounded up.

[0054] Specifically, when H is 4000m, L2 = (4000m - 1000m) / 500m × 2mm + 2mm = 14mm, meaning that the length of the pressure regulating cylinder 400 outside the fan 300 from the air inlet 310 boundary is 14mm, and the air pressure is increased by 280Pa; when H is 4000m and T is 20℃, L2 = (4000m - 1000m) / 500m × 2mm + 2mm = 14mm, and the length of the pressure regulating cylinder 400 outside the fan 300 is not affected by temperature.

[0055] Further, refer to Figures 2 to 4 The information identification module includes a temperature sensor 500 and a WIFI module 600; the temperature sensor 500 is used to read the local temperature and transmit the temperature information to the main controller 100; the WIFI module 600 is used to connect to the network to read the local altitude and transmit the altitude information to the main controller 100; the drive component 200 includes a stepper motor 210 and a ball screw 220; the output end of the stepper motor 210 is connected to the ball screw 220, and the ball screw 220 is connected to the pressure regulating cylinder 400.

[0056] When a gas water heater is used in winter (when the weather is cold, the air density is high, and the gas pressure is high), the water heating steps are as follows: First, connect the gas water heater to the power supply; press the power switch of the gas water heater; press the start button on the control panel of the gas water heater; the WIFI module 600 automatically connects to the WIFI network and reads the local weather; the temperature sensor 500 at the air inlet 310 reads the temperature information; before combustion starts, the displacement distance of the pressure regulating cylinder 400 is adjusted by the software algorithm, specifically based on 10℃, and the temperature difference is calculated by the software program to control the pressure regulation. For every 5°C decrease in temperature, the pressure regulating cylinder 400 moves 2mm into the fan 300. The main controller 100 transmits a reverse signal to the stepper motor 210, causing the ball screw 220 to retract, which in turn causes the pressure regulating cylinder 400 to extend from the air inlet 310. After extending, the internal resistance of the fan 300 increases, the pressure loss increases, and the overall air pressure of the fan 300 decreases. When it moves to the calculated designated position, the main controller 100 cuts off the power to the stepper motor 210. The above steps are completed before the water flow rate reaches the designated speed. The fan 300 starts and ignites.

[0057] When a gas water heater is used in high-altitude areas (thin air, low air pressure), the water heating steps are as follows: First, connect the gas water heater to the power supply; press the power switch; press the start button on the control panel; the WIFI module 600 automatically connects to the WIFI network and reads the local altitude; the temperature sensor 500 at the air inlet 310 reads the temperature information; before combustion starts, the pressure regulating cylinder 400's displacement distance is adjusted by a software algorithm. Using sea level 0m as a reference, the software program calculates the altitude difference to control the displacement distance of the pressure regulating cylinder 400. If the altitude is below 1000m, the area is considered a non-high-altitude area, and the pressure regulating cylinder 400 remains stationary; if the altitude is above 1000m, the pressure regulating cylinder 400 remains stationary. If the elevation is above 1000m, the area is determined to be a high-altitude area. For the first 1000m, the pressure regulating cylinder 400 moves 2mm outward from the air inlet 310 of the fan 300. Subsequently, for every 500m increase in elevation, the pressure regulating cylinder 400 moves 2mm outward from the air inlet 310. The main controller 100 transmits a forward rotation signal to the stepper motor 210, causing the ball screw 220 to retract, which drives the pressure regulating cylinder 400 to extend outward. After extension, the internal resistance of the fan 300 decreases, the air pressure loss decreases, and the total pressure of the fan 300 increases. When it moves to the calculated designated position, the main controller 100 cuts off the power to the stepper motor 210. The above steps are completed before the water flow rate reaches the designated speed. The fan 300 starts and ignites.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
