[0002] In the field of heating control for drinking water equipment, the boiling point of water is affected by ambient air pressure. As altitude increases, air pressure decreases, and the boiling point will decrease accordingly. If temperature control parameters for plain environments are used for heating, it can easily lead to safety hazards.

[0003] Therefore, existing water dispensers typically detect the boiling point of water upon initial power-on to adjust temperature control parameters for different atmospheric pressure environments. It is evident that automatic boiling point detection based on varying atmospheric pressure is crucial for ensuring the safe and stable operation of water dispensers at different altitudes.

The temperature of the liquid inside the water storage component is obtained based on the water temperature sensor. During the first heating stage when the liquid temperature is lower than the first preset temperature, a first proportional coefficient is determined based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time. During the second heating stage after the liquid temperature reaches or exceeds the first preset temperature, a second proportional coefficient is determined based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time. If the second proportional coefficient and the first proportional coefficient satisfy a set proportional relationship, then the liquid temperature currently detected by the water temperature sensor is determined as the boiling point value.

[0008] In some embodiments, the method further includes: If the second proportional coefficient does not satisfy the set proportional relationship with the first proportional coefficient, and the current liquid temperature rises to the second preset temperature, then the second preset temperature is set as the boiling point value.

[0009] In some embodiments, after the step of determining the liquid temperature currently detected by the water temperature sensor as the boiling point value if the second proportional coefficient and the first proportional coefficient satisfy a set proportional relationship, the method further includes: After the heating unit heats the liquid in the water storage component and maintains it at the boiling point value for a preset time, the heating unit is controlled to stop heating.

[0010] In some embodiments, after the step of determining the liquid temperature currently detected by the water temperature sensor as the boiling point value if the second proportional coefficient and the first proportional coefficient satisfy a set proportional relationship, the method further includes: The boiling point value is sent to any smart device connected to the drinking water equipment.

The first proportional coefficient determining unit is used to determine the first proportional coefficient based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time during the first heating stage when the liquid temperature is lower than the first preset temperature. The second proportional coefficient determination unit is used to determine the second proportional coefficient based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time during the second heating stage after the liquid temperature reaches or exceeds the first preset temperature. The boiling point determination unit is used to determine the liquid temperature currently detected by the water temperature sensor as the boiling point value if the second proportional coefficient and the first proportional coefficient satisfy a set proportional relationship.

[0012] A third aspect of this application provides a drinking water device, the drinking water device comprising: Water storage components; A heating unit is disposed on the water storage component and is used to heat the liquid in the water storage component; A water temperature sensor is installed on the water storage component to detect the liquid inside the water storage component; Memory, used to store executable program code; A processor is configured to call and run the executable program code from the memory, causing the drinking water device to perform the boiling point detection method as described in any of the above embodiments.

[0013] In some embodiments, the water storage assembly includes a hot tank, and the probe of the water temperature sensor is disposed inside the hot tank and spaced apart from the wall of the hot tank.

[0017] In the above technical solution, constant power heating ensures stable energy input, and a water temperature sensor collects temperature data in real time. A proportional coefficient is calculated in stages based on the difference in linear characteristics before and after the boiling point. The first and second proportional coefficients are obtained based on the heating characteristics of the water dispenser and the physical properties of the liquid, making them adaptable to water storage components of different volumes and power, exhibiting strong compatibility. Then, by comparing the two proportional coefficients, the boiling point is determined using the difference in liquid heating characteristics before and after the boiling point, without relying on preset model parameters such as temperature thresholds or time parameters. This overcomes the interference of external factors such as heat preservation effect and power supply voltage fluctuations on the detection results, improving the accuracy of boiling point detection.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0025] To improve the safety of drinking water equipment operating at different altitudes, this application provides a boiling point detection method for use in drinking water equipment. Please refer to... Figure 1 , Figure 1 This is a schematic diagram of the water circuit of the drinking water device in this embodiment. The drinking water device includes a water storage component 10 for storing liquid (usually drinking water), a heating unit 20, and a water temperature sensor 30. The heating unit 20 can be a heating wire, heating tube, etc., and is disposed on the water storage component 10 for heating the liquid inside the water storage component 10. The water temperature sensor 30 is also disposed on the water storage component 10 for detecting the temperature of the liquid inside the water storage component 10. The following describes in detail each step of the boiling point detection method using the drinking water device.

[0026] Please see Figure 2 , Figure 2 This is a schematic flowchart of a boiling point detection method provided in an embodiment of this application. The method in this embodiment may include the following steps S10-S50.

[0027] Step S10: Control the heating unit 20 to heat the liquid in the water storage component 10 at a constant power.

[0028] Specifically, the heating unit 20 of the water dispenser is set to a constant heating power P by the controller of the water dispenser, so that the input power of the heating unit remains constant during the heating process. During the heating process, the relationship between the input energy x(t) of the heating unit 20 and the heating time t satisfies x(t)=P*t. Setting a constant power can avoid the deviation in the calculation of input energy due to power fluctuations.

[0029] Step S10: Obtain the liquid temperature inside the water storage component 10 based on the water temperature sensor 30.

[0030] In this embodiment, the water temperature sensor 30 can either collect liquid temperature data in real time and transmit it to the controller, or it can collect temperature data intermittently.

[0031] Step S30: During the first heating stage when the liquid temperature is lower than the first preset temperature, a first proportional coefficient is determined based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time.

[0032] In this embodiment, when the liquid is heated below its boiling point, the absorbed heat is mainly used to raise the temperature, with almost no significant vaporization. Therefore, the temperature change exhibits a linear characteristic. When heated below the boiling point, the liquid temperature rise ΔT and the input energy x(t) of the heating unit 20 satisfy ΔT = m*x(t), where m is a system constant determined by the volume, material, and insulation performance of the water storage component 10. Since the heating power P is constant, the input energy x(t) = P*t. Substituting these values, we can derive ΔT = m*P*t = b1*t, where b1 is the first proportionality coefficient, which is the product of m and P, reflecting the heating characteristics of the drinking water device below the boiling point.

[0033] Specifically, the first heating stage is set according to a first preset temperature. Considering that the boiling point of water at an altitude of 5000 meters is approximately 83℃, the first preset temperature is selected to be close to this value, such as 80℃, 81℃, 82℃, 83℃, etc., so that the liquid is always in a state of heating below the boiling point during the first heating stage, avoiding the interference of vaporization on the linear relationship. In the first heating stage, the controller collects temperature data at multiple time points through the water temperature sensor 30, calculates the temperature rise value ΔT in each time interval, that is, the difference between the current temperature and the initial temperature or the temperature at the previous collection time, and then performs linear fitting of multiple sets of temperature rise values ​​ΔT with the corresponding heating time t, and finally determines the first proportional coefficient b1. The first proportional coefficient in this embodiment is obtained based on the heating characteristics of the drinking water equipment and the physical properties of the liquid, without relying on preset model parameters, and can be adapted to water storage components 10 with different volumes and different power, with strong compatibility.

[0034] Step S40: During the second heating stage after the liquid temperature reaches or exceeds the first preset temperature, a second proportional coefficient is determined based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time.

[0035] Specifically, when the liquid temperature enters the second heating stage, meaning the liquid is approaching its boiling point at the current altitude, the liquid begins to gradually vaporize as the temperature rises. At this point, part of the heat input to the heating unit 20 is used to maintain the liquid's temperature rise, and the other part is used to overcome the latent heat of vaporization, resulting in a weaker linear relationship between the temperature rise and heating time. The second proportionality coefficient will be smaller than the first proportionality coefficient. In this step, the detection logic for the second heating stage is the same as that for the first heating stage: the water temperature sensor 30 continuously collects temperature data, and the controller calculates the temperature rise ΔT and the corresponding heating time t in real time. Through linear fitting, ΔT = b2 * t (where b2 is the second proportionality coefficient) is obtained.

[0036] Step S50: If the second proportional coefficient and the first proportional coefficient satisfy the set proportional relationship, then the liquid temperature currently detected by the water temperature sensor 30 is determined as the boiling point value.

[0037] The set ratio can be adjusted according to the actual application scenario. For example, the second ratio coefficient can be less than 0.3, 0.4, 0.5 or 0.6 times the first ratio coefficient. The first ratio coefficient b1 reflects the linear characteristics of the liquid temperature rise below the boiling point. After reaching the boiling point, the liquid temperature rise efficiency decreases, and b2 will be less than b1. When the two meet the set ratio, it means that the liquid has reached the boiling point and subsequent heating cannot significantly increase the temperature.

[0038] As can be seen from the above, this embodiment ensures energy input stability through constant power heating, uses a water temperature sensor 30 to collect temperature data in real time, calculates a proportional coefficient in stages based on the difference in linear characteristics before and after the boiling point, and determines the boiling point by comparing the two proportional coefficients and utilizing the difference in liquid heating characteristics before and after the boiling point. This eliminates the need to rely on fixed temperature thresholds or time parameters, overcomes the interference of external factors such as heat preservation effect and power supply voltage fluctuations on the detection results, and improves the accuracy of boiling point detection. At the same time, after determining the boiling point value, the water dispenser can automatically adjust the temperature control parameters (such as lowering the heating stop temperature) to avoid overheating of the liquid due to the decrease in boiling point, ensuring the safety of use in different altitude environments.

[0039] In some embodiments, please refer to Figure 2 and Figure 3 Step S50: If the second proportional coefficient and the first proportional coefficient satisfy a set proportional relationship, then the liquid temperature currently detected by the water temperature sensor 30 is determined as the boiling point value, specifically including: Step S51: If the second proportional coefficient b2 and the first proportional coefficient b1 satisfy b2≤k*b1, then the liquid temperature currently collected by the water temperature sensor 30 is determined as the boiling point value under this environment, where k is a pre-set proportional threshold. This embodiment utilizes the difference in liquid temperature rise characteristics before and after the boiling point, and by setting the proportional relationship b2≤k*b1, the boiling point determination becomes more accurate. This allows it to adapt to drinking water equipment with different power and volume, while also reducing the probability of misjudgment due to external factors such as differences in scale insulation effect and slight fluctuations in power supply voltage.

[0040] Furthermore, in some embodiments, the aforementioned proportional threshold k is specifically set to 0.5. Considering the boiling point of water at an altitude of 5000 meters (83°C), once a liquid reaches its boiling point, its heating efficiency typically drops to below 50% of the boiling point's capacity (i.e., b2 ≤ 0.5 * b1). From the perspective of the actual working scenario of the drinking water equipment, k = 0.5 ensures detection sensitivity. In a high-altitude environment, when the liquid temperature reaches approximately 83°C, b2 will rapidly drop below 0.5b1, allowing for timely determination of the boiling point.

[0041] In some embodiments, please refer to Figure 4 The boiling point detection method further includes: step 60, if the second proportional coefficient b2 and the first proportional coefficient b1 do not satisfy the set proportional relationship (i.e. b2>k*b1), and the water temperature sensor 30 detects that the current liquid temperature has risen to the second preset temperature, then the second preset temperature is set as the boiling point value.

[0042] In this embodiment, the second preset temperature is set based on the boiling point characteristics of water in a plain environment. In plain areas, the air pressure is stable, and the boiling point of water is close to 100°C. To avoid excessive boiling leading to overflow or energy waste, the second preset temperature is typically set slightly below 100°C, such as 95°C, 96°C, or 97°C. In a plain environment, after the liquid is heated to the first preset temperature, the heating efficiency remains high because it has not yet reached the boiling point; b2 is always greater than kb1. Heating continues until the temperature reaches the second preset temperature. Thus, this step covers the boiling point detection scenario. For low-altitude environments such as plains, there is no need to continuously wait for the proportional coefficient to meet the conditions; the boiling point value can be directly determined through the second preset temperature. This shortens the detection time, improves the heating efficiency of the drinking water equipment, avoids energy waste caused by ineffective heating, and ensures the safety of use in plain environments.

[0043] In some embodiments, please refer to Figure 5 After step S50, the method further includes step S70, controlling the heating unit 20 to continue heating the liquid in the water storage component 10 at a constant power, maintaining the liquid temperature at the boiling point value for a preset time, and then controlling the heating unit 20 to stop heating.

[0044] Specifically, the liquid is maintained at its boiling point for a preset time, such as 15 seconds, 30 seconds, or 60 seconds. After determining the boiling point, the controller monitors the liquid temperature in real time via a water temperature sensor 30. When the temperature drops below the boiling point, the heating unit 20 is activated to supplement heating. When the temperature reaches the boiling point, heating is maintained until the preset time is completed, at which point the heating circuit is cut off. This process avoids temperature fluctuations caused by stopping heating as soon as the boiling point is reached, ensuring a uniform and stable liquid temperature and improving the user experience.

[0045] In some embodiments, please refer to Figure 6 After step S50, the method further includes step S80, which sends the detected boiling point value to any smart device connected to the drinking water device.

[0046] Specifically, the boiling point value can be transmitted via the communication module of the water dispenser, such as a WiFi module or Bluetooth module, while the smart device receiving the boiling point value can be a smartphone, a smart home control screen, a tablet, etc. In this embodiment, this step realizes information interaction between the water dispenser and the smart terminal. After obtaining the boiling point value, the controller of the water dispenser converts it into standardized data and transmits it to the bound smart device through a preset communication protocol. Users can view the current boiling point value and corresponding altitude reference information in real time through the smart device's APP or control interface. In this way, users can intuitively understand the working status and environmental parameters of the water dispenser, improving the intelligence level of the water dispenser and the user interaction experience.

[0047] This application also provides a boiling point detection device, which includes a heating control unit, a liquid temperature acquisition unit, a first proportional coefficient determination unit, a second proportional coefficient determination unit, and a boiling point determination unit.

[0048] The heating control unit controls the heating unit 20 to heat the liquid in the water storage component 10 at a constant power; the liquid temperature acquisition unit acquires the liquid temperature in the water storage component 10 based on the water temperature sensor 30; the first proportional coefficient determination unit determines the first proportional coefficient based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time during the first heating stage when the liquid temperature is lower than the first preset temperature; the second proportional coefficient determination unit determines the second proportional coefficient based on the linear fitting relationship between the temperature rise of the liquid and the corresponding heating time during the second heating stage when the liquid temperature reaches or exceeds the first preset temperature; and the boiling point determination unit determines the liquid temperature currently detected by the water temperature sensor 30 as the boiling point value if the second proportional coefficient and the first proportional coefficient satisfy a set proportional relationship.

[0049] In some embodiments, such as Figure 1As shown, the water storage assembly 10 includes a heating tank 11 for storing the liquid to be heated. The probe of the water temperature sensor 30 extends into the interior of the heating tank 11 and maintains a preset distance from the wall of the heating tank 11, without directly contacting the wall. In this embodiment, if the probe were in contact with the wall, the detected temperature would be affected by the conductive heat of the wall, leading to distortion in the actual liquid temperature detection. The spaced-out design allows the probe to be immersed in the liquid, acquiring the liquid temperature in real time and improving the accuracy of temperature detection.

[0050] Furthermore, in some embodiments, the drinking water device is also equipped with a filter assembly 50, which is connected in series between the water source and the heating tank 11 to pre-treat the raw water before it enters the heating tank 11. Specifically, it can adopt a combination of PP cotton and activated carbon, or a combination of PP cotton and RO reverse osmosis membrane. Through multi-stage filtration, it can not only ensure the health of the user's drinking water, but also prevent impurities from adhering to the surface of the heating unit 20 and affecting the heating efficiency.

[0051] In some embodiments, the hot tank 11 is provided with a water inlet 1101 for replenishing liquid, a hot water outlet 1103 for users to access hot water, and a steam outlet 1102, which is used to discharge steam generated by the boiling of liquid during the heating process. Correspondingly, the water storage assembly 10 also includes a cold tank 12 for providing warm or cold water. The cold tank 12 is provided with independent warm water chamber 1201 and cold water chamber 1202. The side wall or top of the warm water chamber 1201 is provided with a steam inlet 1203. The steam inlet 1203 is sealed and connected to the steam outlet 1102 of the hot tank 11 through a preset connecting pipe to form a complete steam transmission channel.

[0052] In this embodiment, when the hot tank 11 heats the liquid to the boiling point, it generates a large amount of high-temperature steam. If the steam is directly discharged, it will waste heat. However, in this embodiment, the high-temperature steam is introduced into the warm water chamber 1201 of the cold tank 12 through the steam channel. The residual heat of the steam is used to heat the liquid in the warm water chamber 1201, so that the warm water chamber 1201 can continuously provide suitable drinking water (such as 40℃-60℃). There is no need to configure an independent heating unit 20 for the warm water chamber 1201, which greatly saves the energy consumption of the drinking water equipment. In some embodiments, the cold tank 12 achieves the cooling function of the cold water chamber 1202 through a heat pump assembly 40. The heat pump assembly 40 includes a compressor, an evaporator, and a condenser. The evaporator can be embedded inside the cold water chamber 1202 or attached to the wall of the cold water chamber 1202. Through the heat exchange effect of the heat pump cycle, the liquid temperature of the cold water chamber 1202 is reduced, thus achieving cold water supply. The water inlet 1101 of the hot tank 11 is connected to the warm water chamber 1201 of the cold tank 12, so that the filtered water first enters the warm water chamber 1201 for preheating, and then flows into the hot tank 11 for heating, further improving the heating efficiency of the hot tank 11 and shortening the hot water preparation time. In addition, the cold tank 12 is also equipped with a warm water outlet 1206 and a cold water outlet 1204, corresponding to the warm water chamber 1201 and the cold water chamber 1202, respectively, to meet the user's simultaneous needs for drinking water at different temperatures and improve the convenience of using the equipment.

[0053] In some embodiments, the cold tank 12 includes a tank body 121 and a partition 122. The partition 122 divides the interior of the tank body 121 into two independent chambers distributed vertically along the height direction of the tank body 121: a warm water chamber 1201 at the top and a cold water chamber 1202 at the bottom. One end of the connecting channel 1205 is connected to the warm water chamber 1201, and the other end is connected to the inlet 1101 of the hot tank 11 via a pipe, forming a liquid supply channel from the cold tank 12 to the hot tank 11.

[0054] Specifically, the connecting channel 1205 can be implemented as follows: a hollow rod extends integrally from the side of the partition 122 facing the cold water chamber 1202, the inner cavity of the rod being the connecting channel 1205. The lower end of the rod connects to the water inlet 1101 of the hot water tank 11, and the upper end passes through the partition 122 and connects to the warm water chamber 1201; or, mounting holes are opened on the partition 122, and an independent connecting pipe is connected through the mounting holes, with one end of the connecting pipe connected to the water inlet 1101 of the hot water tank 11 through the mounting holes. In this embodiment, the functional partitioning of the cold water tank 12 is achieved through a partition 122, enabling the cold water tank 12 to integrate both warm water storage and cold water storage functions, simplifying the overall structure of the equipment; while the setting of the connecting channel 1205 optimizes the water circuit layout, eliminating the need for additional long-distance external pipes to achieve liquid communication between the water source and the hot water tank 11, shortening the liquid flow path, and improving the compactness and operational stability of the drinking water equipment.

[0055] In some embodiments, the drinking device further includes a processor and a memory. The memory is electrically connected to the processor. The memory stores executable program code; the processor retrieves and runs the executable program code from the memory, causing the drinking device to perform the boiling point detection method as described in any of the above embodiments.
