BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] Figure 1 It is a flow chart of the water temperature control method for a water dispenser of the present invention. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1 As shown, the present invention is a water temperature control method for a water dispenser. In some embodiments, process 100 can be executed by a processor, such as Figure 1 As shown, process 100 may include the following steps.

[0022] Step 101, using a temperature sensor to obtain real-time water temperature data in the water dispenser.

[0023] The temperature sensor is a sensor for detecting water temperature, which can measure the temperature of the water inside the water dispenser in real time and convert it into an electronic signal. In some embodiments, the temperature sensor may include a thermocouple, an RTD (resistance temperature detector), etc.

[0024] Real-time water temperature data refers to the water temperature value measured by the temperature sensor at a certain moment, in degrees Celsius (°C).

[0025] In some embodiments, the processor can collect water temperature data in real time through a temperature sensor installed inside the water dispenser. The water temperature data can be converted into an electrical signal by a measuring chip of the sensor and processed and recorded by the system controller. The real-time water temperature data obtained refers to the specific value of the water temperature at each moment.

[0026] The water dispenser mentioned in the present invention is a device that can heat water and maintain a certain temperature, and has a certain heating power and adjustment function.

[0027] Step 102, filtering and denoising the real-time water temperature data to obtain stable water temperature data.

[0028] Filtering refers to removing the noise in a signal through mathematical algorithms or electronic circuits to make the signal smoother.

[0029] Denoising refers to removing the noise generated by external interference or other unstable factors in the data collected by the sensor, making the data more accurate.

[0030] Stable water temperature data refers to relatively stable water temperature data obtained after filtering and denoising. It is not affected by instantaneous fluctuations or noise and can better represent the actual situation of the current water temperature.

[0031] In some embodiments, the processor may apply a filtering algorithm, such as a low-pass filter, a Kalman filter, etc., to the acquired real-time water temperature data. The filtering process may be implemented by programming, and the parameters of the filter may be set to remove short-term fluctuations (noise) and other irrelevant interference factors. The water temperature data after filtering and denoising is more stable and can more accurately reflect the actual change trend of the water temperature.

[0032] Step 103, in response to the stable water temperature data being lower than a preset threshold, obtaining the current ambient temperature and the current ambient humidity.

[0033] Ambient temperature refers to the air temperature around the water dispenser, measured in degrees Celsius (°C). Ambient temperature can affect the heating efficiency of the water dispenser.

[0034] Ambient humidity refers to the water vapor content in the air, usually expressed as relative humidity (%). When the humidity is high, heat is not easy to dissipate, affecting the heating effect.

[0035] In some embodiments, the processor may obtain current ambient temperature data through an ambient temperature sensor, which may include a thermometer, a thermocouple, etc., and obtain current ambient humidity data through a humidity sensor, which may include a capacitive humidity sensor, an impedance humidity sensor, etc.

[0036] The preset threshold is a pre-set temperature threshold. When the obtained steady water temperature data is lower than the preset threshold, for example, 10 degrees Celsius, 5 degrees Celsius, etc., the current ambient temperature and the current ambient humidity can be obtained, and subsequent steps can be performed. If the steady water temperature data is greater than or equal to the preset threshold, it can be heated according to the conventional water dispenser heating method. The preset threshold can be set by the user according to needs and is not limited to the temperature value of the above example.

[0037] Step 104: Determine an environmental compensation coefficient based on the current ambient temperature and the current ambient humidity.

[0038] The environmental compensation coefficient is a coefficient used to reflect the influence of environmental factors (temperature, humidity) on the heating process. In some embodiments, the environmental compensation coefficient can be a dimensionless value. The environmental compensation coefficient is used to help adjust the demand for heating power to adapt to changes in the external environment.

[0039] In some embodiments, the processor may calculate the environmental compensation coefficient according to the current ambient temperature and humidity using a preset formula or algorithm.

[0040] In some embodiments, determining the environmental compensation coefficient based on the current ambient temperature and the current ambient humidity includes: determining the environmental compensation coefficient based on the current ambient temperature and the current ambient humidity by using the following formula (1).

[0041] (1) Among them, λ env is the environmental compensation coefficient, T env is the current ambient temperature, T ref is the reference ambient temperature, H env is the current ambient humidity, H ref is the reference ambient humidity, α is the weight coefficient of ambient temperature on heating efficiency, β is the weight coefficient of ambient humidity on heating efficiency, T ref ≥T env , H env ≥H ref ,λ env It is a dimensionless calculation.

[0042] Since the effect of ambient humidity on the heating efficiency of the water dispenser is smaller than that of ambient temperature, α>β can be set. For example, α can be set to 0.9 and β to 0.1.

[0043] For example, the current ambient temperature may be 5 degrees Celsius, the reference ambient temperature may be normal temperature, for example, 25 degrees Celsius, the current ambient humidity may be 45%RH, and the reference ambient humidity may be 30%RH, 20%RH, 10%RH, etc. For ease of calculation, dimensionless calculation is used when using formula (1) for calculation.

[0044] It should be noted that if the current ambient temperature is greater than the reference ambient temperature, a conventional water dispenser heating control method may be used, and this embodiment does not limit the specific type of conventional heating control method. As for ambient humidity, since the influence of ambient humidity on heating efficiency is smaller than that of temperature, ambient humidity may not be considered, and when the current ambient temperature is greater than the reference ambient temperature, a conventional control method is used.

[0045] Step 105, determining the heating power of the water dispenser based on the environmental compensation coefficient, the stable water temperature data and the target temperature.

[0046] The target temperature is the water temperature target value set by the user, which reflects the ideal water temperature that the water dispenser is expected to heat.

[0047] In some embodiments, determining the heating power of the water dispenser based on the environmental compensation coefficient and the water temperature error includes: determining the heating power of the water dispenser based on the environmental compensation coefficient and the water temperature error by the following formula (2).

[0048] (2) Among them, P ideal (t) is the heating power of the determined water dispenser, m is the mass of water in the water dispenser, c is the specific heat capacity of water, T set is the set target temperature, T(t) is the steady water temperature data, λ env is the environmental compensation coefficient, S is the heating time, T set ≥T(t).

[0049] Step 106: Based on the heating power, adjust the output power of the heater of the water dispenser so that the water temperature of the water dispenser reaches the target water temperature.

[0050] The output power of the heater refers to the power input when the heater of the water dispenser is actually working, which is used to control the heating capacity of the heater.

[0051] In some embodiments, adjusting the output power of the heater of the water dispenser based on the heating power may include the following operations.

[0052] S10, obtaining brand characteristic data of the water dispenser.

[0053] Brand characteristic data refers to the brand, model and other related parameters of the water dispenser and the characteristic data of the specific heating technology. Brand characteristic data includes the heating efficiency, heat loss coefficient, maximum power of the heater, optimal working range and other performance parameters of the water dispenser.

[0054] In some embodiments, the brand characteristic data of the water dispenser may be stored in the hardware of the device or obtained through the product manual. The processor may read and obtain the data through the management system of the device or through the communication protocol with the control unit of the device.

[0055] S11, optimizing the heating power based on the brand characteristic data to obtain an optimized heating power.

[0056] Optimized heating power refers to the heating power adjusted according to the brand characteristic data. Optimized heating power can make the heating process both efficient and prevent overheating or energy waste. Optimized heating power not only considers heating efficiency, but also environmental factors, target water temperature and the working characteristics of the heater.

[0057] In some embodiments, the processor can calculate the optimized heating power by obtaining brand characteristic data, such as heating efficiency, maximum power, heat loss coefficient, etc.

[0058] In some embodiments, optimizing the heating power based on the brand characteristic data to obtain the optimized heating power may include the following operations.

[0059] S20: Determine the brand heating efficiency of the water dispenser based on the brand characteristic data.

[0060] Brand heating efficiency refers to the heating efficiency of the brand and model of the water dispenser, which can be expressed by the ratio of the actual heating capacity of the equipment under standard conditions to its rated power. It is a dimensionless coefficient that indicates the efficiency of the heater in converting electrical energy into thermal energy.

[0061] In some embodiments, the processor can obtain parameters related to heating efficiency from the brand characteristic data of the water dispenser, such as the heating efficiency η of the brand under certain standard conditions. The brand heating efficiency can be given in the technical parameters of the device. If it is not clearly marked, it can be measured experimentally: the ratio of the power required to heat the water dispenser to the set temperature to the actual input power under a specific ambient temperature is the heating efficiency.

[0062] S21, based on the brand heating efficiency, the heating power is optimized by the following formula (3) to obtain the optimized heating power.

[0063] (3) Among them, P actual (t) is the optimized heating power, η is the brand heating efficiency, P ideal (t) The heating power of the water dispenser.

[0064] In some embodiments, optimizing the heating power based on the brand characteristic data to obtain the optimized heating power may include the following operations.

[0065] S30: Determine the brand heating efficiency of the water dispenser based on the brand characteristic data.

[0066] S31, based on the brand heating efficiency and the environmental compensation coefficient, optimizing the heating power by the following formula (4) to obtain the optimized heating power; (4) Among them, P actual (t) is the optimized heating power, η is the brand heating efficiency, P ideal (t) the heating power of the water dispenser, λ envIt is noted that the environmental compensation coefficient is used to balance the brand heating efficiency so that the temperature control of the water dispenser can be more accurate.

[0067] S12, output power of the heater of the water dispenser based on the optimized heating power.

[0068] In some embodiments, the processor can adjust the output power of the heater to achieve optimal control of the water temperature of the water dispenser.

[0069] In this embodiment, the heating power of the water dispenser is optimized in combination with the heating efficiency contained in the brand characteristic data. This optimization not only improves energy efficiency, but also avoids excessive or insufficient heating, thereby achieving precise water temperature control. During execution, the heating efficiency is first determined, and then the theoretical heating power is adjusted based on the efficiency to ensure that the actual heating power matches the heating efficiency. Finally, the heating power is finely adjusted to ensure that the heating process of the water dispenser is efficient and accurate. Based on the same inventive concept, the present invention also provides a water temperature control system for a water dispenser, the system comprising: The real-time water temperature detection module is used to obtain the real-time water temperature data in the water dispenser using a temperature sensor; A stable water temperature acquisition module is used to filter and remove noise from the real-time water temperature data to obtain stable water temperature data; Environmental data acquisition module, used to obtain the current ambient temperature and current ambient humidity; An environmental compensation coefficient determination module, used to determine the environmental compensation coefficient based on the current ambient temperature and the current ambient humidity; A heating power determination module, used to determine the heating power of the water dispenser based on the environmental compensation coefficient, the stable water temperature data and the target temperature; The control module is used to adjust the output power of the heater of the water dispenser based on the heating power so that the water temperature of the water dispenser reaches the target water temperature.

[0070] Based on the same inventive concept, the present invention also provides a water dispenser, comprising a processor, wherein the processor is used to execute the water temperature control method for the water dispenser as described herein.

[0071] Working principle of the present invention: (1) By optimizing the heating power based on brand characteristic data (such as brand heating efficiency), the present invention can accurately calculate and adjust the heating power, significantly improve the energy efficiency of the heating process, reduce unnecessary energy waste, thereby saving electricity consumption and reducing carbon emissions, and has obvious energy-saving and environmental protection effects. (2) By introducing the environmental compensation coefficient, the present invention can better adapt to low-temperature environmental conditions. This enables the water dispenser to maintain relatively stable and accurate water temperature control in a low-temperature environment, avoiding water temperature fluctuations or heating power imbalance caused by changes in the external environment, and ensuring that users can quickly obtain the required water temperature. (3) In actual applications, changes in environmental conditions may affect the heating effect of the water dispenser. By combining brand heating efficiency and environmental compensation coefficient to optimize heating power, the water dispenser can adapt to changes in different environmental factors and automatically adjust heating power to meet actual needs. The intelligence level of the water dispenser is significantly improved and the user experience is improved. (4) The present invention can optimize the heating power according to the actual heating efficiency and environmental conditions, avoid equipment overload or long-term high-load operation, and can effectively reduce the thermal stress and power consumption of the equipment during the heating process, reduce equipment loss and failure rate, and extend the service life of the water dispenser. (5) When using a water dispenser, users can enjoy more stable and rapid water temperature control. Regardless of environmental conditions, the water temperature can be quickly and stably reached to the predetermined temperature, thereby improving the comfort and convenience of use. In addition, due to energy saving and low energy consumption, the electricity bill can be effectively reduced during long-term use, bringing economic benefits to users. (6) The present invention takes into account the heating efficiency characteristics of the water dispenser brand, and can be adjusted and optimized accordingly according to different brands and models of equipment, and has wide applicability.
