Description

Technical Field

[0001] This application relates to the field of gas water heaters, and more particularly to a method for adaptive temperature and humidity control in gas water heaters. Background Technology

[0002] Gas water heaters, as the core heat source equipment in modern homes, have become a key component in enhancing the convenience and comfort of family life due to their outstanding advantages such as powerful performance, instant hot water, and energy efficiency. They are widely used in various scenarios including daily washing, bathing, and kitchen water use. The accuracy, stability, and adaptability of the outlet water temperature directly affect the user experience and safety, and are therefore key indicators for measuring the core performance of gas water heaters. Consequently, their control technology has become a focus of industry research and development and user attention.

[0003] Currently, most mainstream gas water heaters on the market employ a temperature compensation control mechanism. Specifically, a temperature sensor collects the ambient temperature or inlet water temperature of the gas water heater in real time. Then, based on a preset algorithm model, the corresponding temperature compensation value is calculated. Finally, by adjusting core parameters such as combustion power and water flow rate, the preset outlet water temperature is corrected to offset the impact of changes in ambient temperature or fluctuations in inlet water temperature on the actual outlet water temperature.

[0004] However, in real-world applications, the installation environments of gas water heaters in different households often vary significantly. Existing temperature compensation control mechanisms are mostly based on fixed scenario presets, lacking the ability to adaptively adjust to diverse installation environments and dynamic water usage scenarios. This makes it difficult to achieve precise and adaptive control of the gas water heater's outlet water temperature. Consequently, even after compensation, existing solutions still do not meet users' actual needs, significantly impacting the user experience. Summary of the Invention

[0026] Optionally, after adjusting the preset outlet water temperature of the gas water heater according to the first temperature compensation value, the method further includes:

[0027] Determine whether the ambient temperature is lower than a first preset temperature threshold;

[0028] If so, after the gas water heater has been supplying water for a preset duration, the outlet water temperature of the gas water heater will be gradually adjusted according to the preset temperature adjustment formula.

[0052] To address the technical problem of accurately adjusting the outlet water temperature of gas water heaters in existing technologies, this application provides a gas water heater temperature and humidity adaptive device that can achieve precise adjustment of the outlet water temperature of gas water heaters.

[0053] Figure 1a This is one of the flowcharts illustrating a gas water heater temperature and humidity adaptive method according to an embodiment of this application. In one embodiment, the method is applied to a gas water heater, which includes a hot water pipe, and the method includes steps S101-S103.

[0054] S101. Obtain the ambient temperature and humidity of the gas water heater, the length of the hot water pipe, the weather forecast temperature of the area where the gas water heater is located, and the water flow rate of the hot water pipe.

[0055] Please see Figure 1b , Figure 1b This application provides one embodiment of a gas water heater. In one embodiment, the gas water heater integrates a main controller, an outlet water temperature sensor, a wireless communication module, and an ambient temperature and humidity sensor. The ambient temperature and humidity sensor is used to acquire the ambient temperature and humidity of the gas water heater. The wireless communication module is used to obtain the weather forecast temperature for the area where the gas water heater is located from a cloud server.

[0056] Please see Figures 1c-1d , Figure 1c This is a second type of gas water heater provided in the embodiments of this application. Figure 1dThis is a schematic diagram illustrating the acquisition of temperature and humidity via a cloud server, as provided in an embodiment of this application. In one embodiment, the gas water heater includes a water heater and a wireless controller. The water heater includes a main controller, a wireless communication module, and an outlet water temperature sensor. The wireless controller includes a wireless communication module and an ambient temperature and humidity sensor. It should be noted that the ambient temperature and humidity sensor in the wireless controller acquires the ambient temperature and humidity, and then transmits these data to the wireless communication module in the water heater via the wireless communication module in the wireless controller. Additionally, the wireless communication module in the water heater is also used to obtain the weather forecast temperature for the area where the gas water heater is located from the cloud server.

[0057] It should be noted that the wireless communication module can be a WIFI module, a 4G module, or a 5G module. This application does not impose any restrictions on this.

[0058] It should be noted that the length of the hot water pipe can be set manually by the user, or it can be calculated from the historical circulation time and water flow velocity in the zero-cold-water circulation system. Specifically, the length of the hot water pipe is equal to the product of the historical circulation time and the water flow velocity. It should also be noted that gas water heaters include a zero-cold-water circulation system, which is connected to the hot water pipe.

[0059] S102. Determine the first temperature compensation value based on ambient temperature, ambient humidity, length, weather forecast temperature, and water outlet speed.

[0060] The first temperature compensation value is the temperature compensation value for the preset outlet water temperature of the gas water heater. The technical solution of this application comprehensively considers multiple influencing factors of the installation environment (ambient temperature and humidity of the gas water heater, length of the hot water pipe, and weather forecast temperature of the area where the gas water heater is located) and the dynamic water use scenario (outlet water speed of the hot water pipe), and obtains an accurate temperature compensation value through multi-parameter collaborative calculation.

[0061] S103. Adjust the preset outlet water temperature of the gas water heater according to the first temperature compensation value.

[0062] The preset outlet water temperature is the temperature set for each gas water heater based on actual experience. This application does not impose any restrictions on this. The final outlet water temperature in actual operation of the gas water heater is the preset outlet water temperature plus a first temperature compensation value. For example, if the first temperature compensation value is 1℃ and the preset outlet water temperature is 40℃, then the final outlet water temperature will be 41℃.

[0063] This application provides a method for adaptive temperature and humidity control in a gas water heater. The method is applied to a gas water heater, which includes a hot water pipe. The method includes: acquiring the ambient temperature and humidity of the gas water heater, the length of the hot water pipe, the forecast temperature of the area where the gas water heater is located, and the water flow rate of the hot water pipe; determining a first temperature compensation value based on the ambient temperature, ambient humidity, length, forecast temperature, and water flow rate; and adjusting the preset water flow temperature of the gas water heater based on the first temperature compensation value. Therefore, the technical solution of this application acquires the ambient temperature and humidity of the gas water heater, the length of the hot water pipe, the forecast temperature of the area where the gas water heater is located, and the water flow rate of the hot water pipe. Then, a first temperature compensation value is determined based on the ambient temperature, ambient humidity, length of the hot water pipe, forecast temperature, and water flow rate. Finally, the preset water flow temperature of the gas water heater is adjusted based on the first temperature compensation value. Therefore, the technical solution in this application comprehensively considers multiple influencing factors, including the installation environment (ambient temperature and humidity of the gas water heater, length of the hot water pipe, and forecast temperature of the area where the gas water heater is located) and the dynamic water usage scenario (water flow rate of the hot water pipe). Through multi-parameter collaborative calculation, a precise temperature compensation value is obtained, thereby achieving accurate adjustment of the outlet water temperature. This design effectively avoids frequent deviations in outlet water temperature from being too cold or too hot, significantly improving the user experience.

[0064] In one embodiment, S102 specifically includes the following steps: S1021-S1023.

[0065] S1021. Determine the second temperature compensation value based on the ambient temperature, weather forecast temperature, length, and water outlet speed.

[0066] In one embodiment, S1021 specifically includes the following steps: S10211-S10212.

[0067] S10211. Calculate the temperature difference between the ambient temperature and the weather forecast temperature.

[0068] S10212. Calculate the second temperature compensation value based on the temperature difference, length, and water outlet speed.

[0069] It should be noted that S10211-S10212 will be explained in detail below.

[0070] In this embodiment, the user's heating intensity is obtained by calculating the temperature difference between the ambient temperature and the forecast temperature, thereby determining the insulation capacity of the hot water pipes. A second temperature compensation value is then determined by combining the temperature difference, pipe length, and water flow rate. This second temperature compensation value is used to compensate for the preset outlet temperature of the gas water heater. The temperature difference is used to assess the user's heating intensity.

[0071] In one embodiment, the formula for calculating the second temperature compensation value is as follows:

[0072]

[0073]

[0074] in, The temperature difference between the ambient temperature and the forecast temperature. L represents the temperature difference between the hot water at the outlet of the hot water pipe and the hot water at the outlet of the gas water heater, where L is the length of the hot water pipe. The water flow rate from the hot water pipe. This is the temperature drop coefficient per unit time for hot water pipes, expressed in °C / s. This is the strength coefficient of the underfloor heating system. This is the second temperature compensation value.

[0075] As can be seen from the embodiments of this application, the heat dissipation of the hot water pipe's outer surface to the environment is equal to the energy loss of the fluid between the hot water pipe outlet and the gas water heater outlet. The heat dissipation of the pipe's outer surface to the environment can be represented by the difference between the hot water temperature at the hot water pipe outlet and the hot water temperature at the gas water heater outlet. The calculation formula is:

[0076] Formula (1)

[0077] in, This refers to the heat loss power of the hot water pipes, measured in watts (W). This refers to the mass flow rate of hot water in the hot water pipe, expressed in kg / s. This is the specific heat capacity of hot water, expressed in J / (kg*K). This is the difference between the hot water temperature at the outlet of the hot water pipe and the hot water temperature at the outlet of the gas water heater.

[0078] The formula is:

[0079] Formula (2)

[0080] in, This refers to the density of hot water in the hot water pipe, expressed in kg / m³. 3 , d represents the average velocity of the hot water in the hot water pipe, in m / s, and d represents the inner diameter of the hot water pipe, in m.

[0081] According to the basic principles of convective heat transfer:

[0082] Formula (3)

[0083] Where k is the external convective heat transfer coefficient, with units of . k is determined by the material of the hot water pipe, the diameter of the hot water pipe, the surface roughness of the hot water pipe, and the indoor air flow speed. In this example, k is approximately a fixed value.

[0084] The outer surface area of ​​the hot water pipe is , where

[0085] Formula (4)

[0086] Where D is the outer diameter of the hot water pipe and L is the length of the hot water pipe.

[0087] This represents the difference between the average temperature of the hot water in the hot water pipes and the indoor ambient temperature. It should be noted that because the temperature difference between the hot water and the ambient temperature is significant, fluctuations in the ambient temperature have a relatively small impact on this difference. It is approximately a fixed value.

[0088] In this embodiment, formula 4 is first substituted into formula 3, then formulas 2 and 3 are substituted into formula 1, and after simplification, the following is obtained:

[0089]

[0090] As can be seen from the analysis of the above embodiments, , , , , as well as Since it is a fixed value, it can be agreed that:

[0091]

[0092] Therefore,

[0093]

[0094] in In this example, it is defined as the temperature drop coefficient per unit time of the hot water pipe.

[0095] It should be noted that the temperature drop coefficient per unit time for hot water pipes and the underfloor heating strength coefficient are set based on practical experience, and the values ​​for both are between 0 and 1. Additionally, This is used to compensate for heat loss in hot water pipes. The temperature drop coefficient per unit time represents the temperature loss of hot water per unit time it resides in the pipe. The longer the hot water pipe, the greater the heat exchange energy with the external environment, and the greater the corresponding temperature loss. Simultaneously, the slower the water flow rate, the longer the heat exchange time between the hot water and the pipe wall and the external environment, resulting in even greater temperature loss.

[0096] It should be noted that the actual heat dissipation of hot water pipes is related to the temperature difference between the inside and outside of the pipes. If there are additional heating measures such as underfloor heating, the temperature drop coefficient per unit time of the hot water pipes will be reduced. However, the temperature outside the pipes is usually not directly measurable, nor is it possible to directly obtain the temperature of the underfloor heating system in the user's home. Therefore, it is necessary to... To determine if additional heating measures are in place, the actual outlet water temperature of the gas water heater is adjusted accordingly. If there is a temperature difference between indoors and outdoors in winter, underfloor heating is assumed to be present; the greater the temperature difference, the lower the actual temperature drop in the hot water pipes is considered, thus reducing the adjustment. The value of .

[0097] It should be noted that in the calculation of the second temperature compensation value, the ambient temperature is a negative feedback compensation variable.

[0098] S1022. Based on the ambient temperature and humidity, find the preset temperature compensation table to obtain the third temperature compensation value.

[0099] Table 1 is the preset temperature compensation table.

[0100] Table 1

[0101]

[0102] It should be noted that the preset temperature compensation table is a two-dimensional compensation table that includes ambient temperature and ambient humidity. When the ambient temperature is lower than the comfortable temperature (generally considered to be 26℃), the higher the ambient humidity, the lower the perceived temperature for the user (e.g., in the damp and cold weather of southern regions). Therefore, increasing the actual outlet water temperature of the gas water heater can improve the comfort of bathing. Conversely, when the ambient temperature is higher than the comfortable temperature, the higher the humidity, the higher the perceived temperature for the user (e.g., in the sweltering heat of summer), so decreasing the actual outlet water temperature of the gas water heater can actually improve the comfort of bathing. In this embodiment, the preset temperature compensation table is consulted based on the ambient temperature and ambient humidity to obtain a third temperature compensation value. This third temperature compensation value is used to compensate for the user's bathing comfort. In the process of obtaining the third temperature compensation value, the ambient temperature is a positive feedback compensation variable.

[0103] S1023. Determine the first temperature compensation value based on the second temperature compensation value and the third temperature compensation value.

[0104] Specifically, the first temperature compensation value is equal to the sum of the second and third temperature compensation values.

[0105] Please see Figure 1e , Figure 1e This is a second schematic flowchart illustrating a method for adaptive temperature and humidity control in a gas water heater, provided as an embodiment of this application. In one embodiment, prior to S103, the method further includes S104-S106.

[0106] S104. Obtain the target temperature adjustment range of the gas water heater.

[0107] In actual use of gas water heaters, users are often dissatisfied with the temperature control described above and need to manually set the outlet water temperature. This embodiment of the application provides targeted compensation for users' individual needs. Specifically, when a user manually sets the outlet water temperature, the difference between the manually set value and the preset outlet water temperature value is calculated. The target temperature adjustment range is this difference. The preset outlet water temperature value is set at the factory.

[0108] S105. Record the historical temperature adjustment range based on the ambient temperature.

[0109] Historical temperature adjustment records include at least one temperature adjustment range;

[0110] It should be noted that the user's temperature adjustment range will vary significantly with seasonal changes. To eliminate the interference of seasonal factors on the temperature adjustment range, in this embodiment, the ambient temperature is divided into two ranges: a high-temperature range and a low-temperature range, according to a second preset temperature threshold. Each temperature range corresponds to an independent historical temperature adjustment range record. Specifically, the historical temperature adjustment range record for the high-temperature range is the set of data showing the user's adjustment range of the gas water heater's set temperature when the ambient temperature is higher than the second preset temperature threshold. The historical temperature adjustment range record for the low-temperature range is the set of data showing the user's adjustment range of the gas water heater's set temperature when the ambient temperature is lower than or equal to the second preset temperature threshold.

[0111] Preferably, the second preset temperature threshold is 26°C.

[0112] S106. Calculate the average of at least one temperature adjustment range and the target temperature adjustment range, and use the average value as the fourth temperature compensation value.

[0113] It should be noted that the fourth temperature compensation value is used to provide targeted compensation for users' personalized needs.

[0114] The above S103 specifically includes the following steps: S1031.

[0115] S1031. Adjust the preset outlet water temperature of the gas water heater according to the first temperature compensation value and the fourth temperature compensation value.

[0116] It should be noted that the final actual outlet water temperature of the gas water heater is the sum of the preset outlet water temperature, the first temperature compensation value, and the fourth temperature compensation value.

[0117] It should be noted that, Figure 1e In this application embodiment, b1 corresponds to the target temperature adjustment range, and T3 is the ambient temperature. Corresponding to the second temperature compensation value in the embodiments of this application, Corresponding to the third temperature compensation value in the embodiments of this application, This corresponds to the fourth temperature compensation value in the embodiments of this application. Array B1[n] contains historical temperature adjustment range records corresponding to the high temperature range. Array B2[n] contains historical temperature adjustment range records corresponding to the low temperature range. Here, n is an integer greater than or equal to 0, representing the (n+1)th temperature adjustment operation. For example, when n is 0, it represents the 1st temperature adjustment operation.

[0118] It should be noted that, in this embodiment of the application, by analyzing the correlation between user adjustment records and ambient temperature, a user comfort demand model is established, and by distinguishing the different water usage habits of users in summer or winter, a fourth temperature compensation value is added to effectively avoid the water being too hot in summer after the temperature is raised in winter and the water being too cold in winter after the temperature is lowered in summer.

[0119] In one embodiment, after S103, the method further includes S107-S109.

[0120] S107. Determine whether the ambient temperature is lower than the first preset temperature threshold; if yes, proceed to S108; otherwise, proceed to S109.

[0121] The first preset temperature threshold is set based on practical experience. This application does not impose any restrictions on this. Preferably, the first preset temperature threshold is 10℃.

[0122] S108. After the gas water heater has been continuously supplying water for a preset time, the outlet water temperature of the gas water heater is gradually adjusted according to the preset temperature adjustment formula.

[0123] In this embodiment, it is considered that excessively high water temperatures are detrimental to skin health. Therefore, the water supply from the gas water heater is continuously preset for a certain duration. Then, the outlet water temperature of the gas water heater is gradually adjusted according to the preset temperature adjustment formula. The preset duration is... This is a user-defined setting. This application does not impose any restrictions on it. The preset temperature adjustment formula is:

[0124]

[0125] in, This refers to the initial outlet water temperature of the gas water heater. For the temperature gradual change time, This is the temperature compensation coefficient. The ambient temperature for the gas water heater. This is the humidity compensation coefficient. The ambient humidity is T, and the outlet water temperature is T.

[0126] It should be noted that in the preset temperature adjustment formula, the calculation of T is dimensionless. The water temperature is gradually reduced based on the temperature and humidity values, so that the skin surface temperature decreases slowly. This avoids the skin surface temperature from being too high and creating too large a temperature difference with the dry and cold air, thereby slowing down the evaporation of moisture. Therefore, only its specific value needs to be extracted, without any unit.

[0127] Furthermore, when the ambient temperature is low, the gas water heater will appropriately increase the actual outlet water temperature through the aforementioned outlet water temperature compensation mechanism to ensure a basic comfortable bathing experience for users. After bathing, the skin's surface oils are washed away, reducing its moisture-locking ability. If the temperature difference between the skin surface and the environment is greater at this time, the rate of moisture evaporation from the skin surface will be faster, making the skin more prone to dryness and cracking. Simultaneously, the lower the ambient humidity, the greater the humidity difference between the skin surface and the environment, which will also accelerate moisture evaporation from the skin surface, further exacerbating skin moisture loss and the risk of damage. Therefore, based on the detected ambient temperature and humidity, the gas water heater dynamically and gradually reduces the outlet water temperature over time, thereby reducing excessive moisture evaporation from the skin after bathing while ensuring user comfort and better protecting skin health.

[0128] In addition, according to the preset temperature adjustment formula, the lower the ambient humidity, the lower the final actual water temperature of the gas water heater after adjustment; the lower the ambient temperature, the lower the final actual water temperature of the gas water heater after adjustment.

[0129] It should be noted that, The value range is 0~3min, and The timing starts from the actual water output from the gas water heater and after a preset time. The timing. For example, if the preset duration... It lasts for 2 minutes. If the gas water heater starts dispensing water at 9:22 PM, then... The timing starts at 9:24 PM and stops at 9:27 PM. Additionally, when... The value is less than 0 or When the value is greater than 3, stop adjusting the actual outlet water temperature of the gas water heater.
