Description

Technical Field

[0001] This invention belongs to the technical field of drinking water, and particularly relates to a water purification and heating method and system based on a spiral waterway structure. Background Technology

[0002] With the increasing demand for safe and convenient drinking water, household water purifiers with integrated heating functions have become an important direction for kitchen terminal equipment. Existing products mostly use straight-through electric heating elements or plate heat exchangers with short, straight water paths to achieve rapid heating. This approach has advantages in initial heating response speed, but it reveals significant shortcomings in continuous high-frequency water intake, fluctuating inlet water temperature, and maintaining thermal efficiency over long-term operation: the initial water temperature is relatively low, the temperature difference between the first cup and the outlet water fluctuates greatly, and energy consumption increases rapidly with scaling. The industry has attempted to modify the water path into a spiral channel to extend the fluid's heating path, improve heat exchange uniformity, and reduce thermal shock; however, once the spiral structure is formed, it lacks adjustability and cannot dynamically compensate for heat exchange degradation caused by water flow rate, target temperature rise, or scale growth. Long-term use still results in thermal efficiency decay and sluggish response. Furthermore, simply increasing heating power to offset efficiency decline often leads to overheating, increased scaling, and higher energy consumption, failing to achieve a balance in household water purification environments that require both limited space and energy efficiency. Meanwhile, existing water system structures also face practical constraints in terms of materials and hygiene: the widely used general engineering plastics are prone to aging and precipitation under high-temperature circulation and chlorine-containing environments; the roughness of the inner wall and the gaps between joints can become breeding grounds for scale and biofilm; the contact between adhesives and dissimilar metals can easily lead to leakage and micro-electrochemical corrosion; and the difficulty in maintenance and cleaning makes it difficult to achieve both thermal efficiency and hygiene safety in the long term. Although some products claim to use spiral guide components to enhance turbulence, the guide components and the shell are not made of the same food-contact grade material system or lack surface inert treatment, making it difficult to balance the frequency of flow channel renewal, contact area, and cleanability. Therefore, how to maintain the advantages of a compact spiral structure while coordinating and adjusting the water channel geometry and heating power to adapt to the decline in thermal efficiency and changes in instantaneous heat load, and on this basis, construct a double-spiral composite flow channel structure made of food-contact grade materials and processes, with an easy-to-clean surface and low scaling, so that the fluid can obtain a larger heated contact area and a more stable rotating and tumbling flow state within a limited volume, reduce temperature maintenance energy consumption, and improve long-term hygiene and reliability, has become a core bottleneck that water purifier heating technology urgently needs to overcome. Summary of the Invention

[0003] This invention proposes a spiral waterway water purification and heating system with structural self-adaptation and energy self-compensation characteristics. The system uses a real-time thermal efficiency model as the detection kernel and constructs a closed-loop coupling of waterway structure, heat conversion efficiency and heating power.

[0004] To achieve the above objectives, a water purification and heating method based on a spiral waterway structure is provided in a first aspect of the present invention, comprising: Calculate the actual heating capacity and normalized ratio of the current thermal efficiency of the water purifier based on the internal data of the water purifier. Real-time water flow and preset target temperature rise are collected, and a heat satisfaction factor is calculated in combination with the current thermal efficiency of the water purifier. The heat satisfaction factor is used to reflect the potential side effects of structural adjustment on the heating device. The adjustment range of the current water channel structure is calculated based on the heat satisfaction factor. The water channel structure is a spiral structure. Based on the adjustment range and the thermal satisfaction factor, combined with the current spiral channel structure path length and the maximum allowable length of the spiral channel structure design, the final structural adjustment amount is calculated, and the path length of the spiral channel is dynamically adjusted based on the final structural adjustment amount. Based on the adjustment length and thermal satisfaction factor of the spiral water channel structure, the target power of the water purifier's heater is calculated, and the final water purification heating power is calculated based on the target power of the heater and the preset base power.

[0005] Preferably, the internal data of the water purifier includes inlet water temperature, outlet water temperature, water flow rate, and heating power; The inlet water temperature is obtained by an NTC thermistor installed before the spiral channel inlet; the outlet water temperature is obtained by an NTC thermistor installed at the end of the spiral channel or near the outlet; the water flow rate is obtained by a miniature turbine flow meter installed at the inlet; the heating power is calculated by the main control chip of the electric heating module by real-time acquisition of the water purifier's current and voltage, where heating power = current. Voltage.

[0006] As a preferred approach, a thermal efficiency model is constructed to normalize and combine the actual temperature rise with the unit energy consumption. The thermal efficiency model quantifies the ratio of the actual temperature rise capacity of the actual water body to the input power at a unit flow rate. The thermal efficiency model is dynamically updated using a short-time window sliding mean method to reduce the calculation error caused by a single disturbance and output the true heating capacity of the water purifier, which is used to assess whether the heating capacity has decreased due to structural degradation or scaling.

[0007] More preferably, in the thermal efficiency model, an initial calibration value of the water purifier is introduced. The initial calibration value is obtained from the standard operating condition record table when the water purifier leaves the factory. This initial calibration value is used to calculate the current thermal efficiency normalization ratio. When the thermal efficiency normalization ratio is less than a preset threshold, it is determined that the current heat conversion capacity of the water purifier is insufficient.

[0008] Preferably, a nonlinear regularization term is added during the calculation of the thermal satisfaction factor to penalize the risk of system inertia amplification caused by blindly extending the structural path under high flow rate or large temperature rise conditions, thereby avoiding over-adjustment.

[0009] Preferably, in the process of calculating the adjustment range, by limiting the maximum adjustment range of the structure and introducing the structural reference adaptation value of the water purifier in the factory calibration state, a defined relationship is established between the adjustment range of the spiral water channel structure and the thermal satisfaction factor. When the adjustment range is positive, it means that the spiral water channel structure path should be extended; when the adjustment range is negative, it means that the spiral water channel structure path should be compressed; and when the adjustment range is zero, it means that the spiral water channel structure does not need to be adjusted.

[0010] Preferably, in the process of calculating the final structural adjustment amount, the target length is first calculated, but the structural adjustment is not performed immediately to avoid frequent structural fluctuations due to small thermal disturbances. The final structural adjustment amount is controlled by introducing a thermal satisfaction suppression coefficient.

[0011] Preferably, in the process of converting the final structural adjustment amount into a specific action command through the drive mechanism in the path length of the dynamically adjustable spiral channel, the specific steps include: If a motor-driven slide rail system is used, the final structural adjustment amount is converted into a number of steps; If shape memory alloy wire is used, the final structural adjustment is converted into a current pulse to control the length; The drive mechanism sends control signals in real time and uses displacement sensors to detect the length of the spiral water channel structure to perform closed-loop verification. The spiral water channel structure is made of food-grade steel.

[0012] As a preferred option, a thermal structure coupling sensing mechanism is also provided. By constructing a heating power correction model, the power setting value of the water purifier is corrected after dynamic adjustment. When the adjustment range of the spiral water channel structure is less than the preset threshold, only slight power compensation is performed; if the adjustment range of the spiral water channel structure is greater than the preset threshold, the power compensation range will be greater than 50%.

[0013] A second aspect of the present invention provides a water purification and heating system based on a spiral waterway structure, comprising: The thermal efficiency status identification module is used to calculate the current actual heating capacity and the current thermal efficiency normalization ratio of the water purifier based on the internal data of the water purifier. The structural adjustment demand derivation module is used to collect real-time water flow and preset target temperature rise, and calculate the heat satisfaction factor in combination with the current thermal efficiency of the water purifier. The heat satisfaction factor is used to reflect the potential side effects of structural adjustment on the heating device. Based on the heat satisfaction factor, the adjustment range of the current water channel structure is calculated. The water channel structure is a spiral structure and the water channel structure is made of food-grade steel. The structural execution module calculates the final structural adjustment amount based on the adjustment range and the thermal satisfaction factor, combined with the current spiral channel structure path length and the maximum allowable length of the spiral channel structure design, and dynamically adjusts the path length of the spiral channel based on the final structural adjustment amount. The heating power setting module is used to calculate the target power of the water purifier's heater based on the adjustment length and thermal satisfaction factor of the spiral water channel structure, and to calculate the final water purification heating power based on the target power of the heater and the preset base power.

[0014] The beneficial technical effects of the present invention are at least as follows: To address the aforementioned issues, this invention provides a spiral water channel heating method and system with structural self-adaptation and energy self-compensation characteristics. Using a real-time thermal efficiency model as the detection kernel, the water channel structure, heat conversion efficiency, and heating power are constructed as a closed-loop coupling. First, a dimensionless thermal efficiency model is constructed using inlet and outlet water temperature, flow rate, and power data, and compared with factory calibration values ​​to quantify the degree of thermal decay. Then, based on the heat satisfaction factor and target temperature rise, the required spiral path adjustment ratio is automatically derived, and a flexible slide rail or shape memory alloy skeleton is driven to perform low-frequency controllable structural changes to the water channel length, achieving feedforward compensation for heat exchange residence time. Finally, combining the actual structural displacement and thermal state weights, the power output of the electric heater is dynamically corrected, ensuring that energy input and structural adjustment are synchronized. Through this integrated structure-thermal-power strategy, the device can maintain a stable outlet water temperature and high heat exchange efficiency under complex operating conditions such as increased scaling, sudden flow changes, or high / low temperature inlet water, while avoiding energy consumption increases and material fatigue caused by excessive power compensation. This significantly improves the energy efficiency, responsiveness, and reliability of the water purifier's heating module during long-term use. Attached Figure Description

[0015] The present invention will be further described with reference to the accompanying drawings, but the embodiments in the drawings do not constitute any limitation on the present invention. For those skilled in the art, other drawings can be obtained based on the following drawings without creative effort.

[0016] Figure 1 This is a flowchart of a water purification and heating method based on a spiral water channel structure according to the present invention.

[0017] Figure 2This is a framework diagram of a water purification and heating system based on a spiral water channel structure according to the present invention. Detailed Implementation

[0018] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In one or more embodiments, such as Figure 1 As shown, a water purification and heating method based on a spiral water channel structure is disclosed, the method comprising the following: S1. Calculate the actual heating capacity and normalized ratio of the current thermal efficiency of the water purifier based on the internal data of the water purifier. The goal of this step is to accurately identify the current thermal efficiency status of the spiral water channel heating device and transform it into a set of explicit, dimensionless indicators, providing a basis for judging whether subsequent structural adjustments are needed. The special feature of the spiral water channel is that its physical geometric path has a significant impact on water residence time and heat exchange efficiency. Therefore, this step does not merely calculate temperature rise or power, but models the relationship between these two into a thermal efficiency expression strongly correlated with the structural state. In engineering practice, many water purification devices suffer from scaling, thermal degradation, and aging of internal pathways, yet lack quantifiable performance evaluation mechanisms. This step aims to address this long-standing problem of the structural performance remaining largely undetectable.

[0020] This step starts by building the model directly from the data that can be collected from within the device: Inlet water temperature Data is collected using an NTC thermistor installed before the spiral channel inlet. The NTC thermistor is connected to the main control board via an ADC port. A sampling period of 1 second is recommended, and signal preprocessing includes one exponential smoothing filter. This data is used to determine the starting temperature of heat exchange, serving as the starting point for subsequent temperature rise calculations. water outlet temperature The temperature is collected by an NTC thermistor installed at the end of the spiral channel or near the outlet. The sampling frequency is consistent with that of the inlet water temperature. To ensure that the temperature at the measurement location can truly reflect the water body rather than the hot wall temperature, a flow-through temperature sensing shell is used to prevent measurement drift. The water flow rate Q is collected by a miniature turbine flow meter installed at the inlet. The output signal is a PWM or analog signal, which is read by the ADC module and converted into a flow rate value. The conversion factor is obtained from factory calibration, and the unit data is processed into a volumetric flow rate per minute. The heating power P is calculated by the main control chip of the electric heating module through real-time acquisition of the water purifier's current I and voltage U. Heating power P = current I For voltage U, in engineering implementation, it is recommended to use a Hall current sensor + voltage divider bridge for sampling, with a sampling period of not less than 1 second and an error controlled within ±2%.

[0021] By constructing a thermal efficiency model with engineering interpretability, we first normalize and combine temperature rise and unit energy consumption to form a basic thermal efficiency expression. The model is defined as follows: ; This model quantifies the ratio of the actual water body's temperature rise capacity to the input power at a unit flow rate. Wherein: The output of the thermal efficiency model represents the real-time heating capacity of the water purifier heater, which represents the system's energy conversion efficiency and is used to measure the heater's real heating capacity under the current structure and state. This indicates the net temperature rise achieved by the water during this heating process; It represents the power load absorbed per unit volume of water and is a true measure of the heating load per unit volume of water.

[0022] The model is dynamically updated using a short time window (20 seconds recommended) moving average method, thereby reducing calculation errors caused by single perturbations. The calculation result is a dimensionless ratio with clear physical meaning and strong comparability, which can be used to assess whether heating capacity decreases due to structural degradation or scaling.

[0023] Considering that the heat transfer coefficient of the spiral channel wall may gradually decrease during long-term operation (e.g., due to scaling or local blockage), an initial calibration value is introduced. This value is recorded under standard operating conditions when the equipment leaves the factory. The normalized ratio of the current thermal efficiency is calculated each time the equipment is run. ; This represents the thermal efficiency decay ratio, used to indicate the percentage decrease in system performance compared to the calibrated state, and is used to determine whether the system is currently operating in an inefficient state. The thermal efficiency value is calibrated and stored in the control chip at the factory for reference.

[0024] when If the current heat conversion capacity is insufficient, a further assessment will be needed to determine if structural adjustments are required. No additional variables other than temperature, flow rate, and electrical power are introduced during this process, thus ensuring the feasibility of the system inputs.

[0025] For example: Assume that at a certain moment, the inlet water temperature is 22°C, the outlet water temperature is 85°C, the flow rate is 1.2 L / min, and the heating power is 1200 W, then: Temperature rise is 63°C; power density per unit flow rate is Then the thermal efficiency model If it leaves the factory ,but It is below the threshold.

[0026] The actual heating capacity in this step The ratio of the current normalized thermal efficiency It will be used directly as one of the input variables for the next step.

[0027] S2. Collect real-time water flow and preset target temperature rise, and calculate the heat satisfaction factor in combination with the current thermal efficiency of the water purifier. The heat satisfaction factor is used to reflect the potential side effects of structural adjustment on the heating device. Calculate the adjustment range of the current water channel structure based on the heat satisfaction factor. The water channel structure is a spiral structure. This step aims to address the issue of decreased thermal efficiency in spiral water channel heating devices caused by structural degradation during long-term operation, based on the actual heating capacity output by the thermal efficiency identification model. Ratio to the normalized current thermal efficiency The input results are used to calculate whether the current spiral channel structure needs adjustment, and the specific amount of adjustment required. .

[0028] Unlike traditional systems that rely solely on power control compensation, this step innovatively introduces a structure-thermal coupling regulation mechanism: by adjusting the user target temperature rise... With the current water flow By combining joint modeling with the thermal response characteristics of the equipment, the adjustment strategy of the structural layer is derived in a formulaic way, so that the system can accurately maintain the stability of heating output by leveraging the structural state. In addition, since the water channel structure in traditional heating modules is cylindrical, this invention uses food-grade steel to make a spiral water channel structure, which has excellent corrosion resistance and can resist the erosion of chemicals such as acids, alkalis, and salts. Long-term use will not cause leakage or pollution due to water corrosion, and it will not release harmful substances after heating, meeting drinking water hygiene standards. The inner and outer surfaces of the spiral tube are smooth, without dead corners, and easy to clean, ensuring that the transported fluid is not contaminated.

[0029] This step serves as a bridge between "thermal performance assessment" and "physical structural action" within the entire patent system. Its significance lies not only in adjusting the structure but also in establishing a feedback mechanism of "thermal efficiency degradation → path redistribution," making it a crucial node for achieving dynamic thermal coordination of the structure.

[0030] Since the length and pitch of the spiral channel directly affect the heat absorption path per unit volume of water, thus influencing the system's heating response speed and heat conversion efficiency, a new structural heat satisfaction factor is first defined to establish the adjustment formula. This index integrates the coupling characteristics of system thermal performance, flow conditions, and target temperature rise, and incorporates a nonlinear regularization term. This is to reflect the impact of structural adjustments on potential side effects such as system delay and overheating. ; in, The structure-thermal satisfaction factor is an important intermediate quantity for determining whether the structure is suitable for the current thermal requirements, and is used as a reference for structural execution in the next step. This indicates the target temperature rise, which is set by the user (e.g., setting the water temperature to 85°C, if the current...). If it is 20°C, then ). This is a dynamic regularization term, designed to penalize the risk of amplified system inertia caused by blindly extending the structural path under high flow rates or large temperature rises. Its specific definition is as follows: ; This is an experience-based penalty factor, typically set by system calibration (e.g., This has the physical significance of buffering the structural adjustment speed under high thermal load; The physical meaning is the thermodynamic inertial resistance term, which avoids over-adjustment caused by system misjudgment; by... Introduction The denominator effectively reduces the system's sensitivity to structural adjustments under high flow rates and high temperature rise conditions, thereby maintaining the stability of the heater response.

[0031] Next, according to Based on the calculation results, establish the structural adjustment amount. Output relationship: ; in: This indicates the maximum range of structural adjustment, representing the upper limit of the system's physical adjustability, and is a factory setting. This indicates that the structural length can be extended or compressed by up to 30%; This represents the structural reference fit value, which is generally taken as the system's factory-calibrated state. The value represents the minimum thermal satisfaction required for a standard structure; This represents the required structural adjustment ratio at present. A positive value indicates that the path should be extended, a negative value indicates that it can be appropriately compressed, and zero indicates that no adjustment is needed. This indicates a structural adjustment command, representing the relative proportion of the path length to be adjusted. For example: If the system currently measures When it left the factory ,but This indicates that the path should be extended by 6.6%.

[0032] In addition, to avoid structural vibration and frequent adjustments, It is recommended to trigger at discrete thresholds (e.g., every 0.05 units) and add a low-pass filter to avoid spike input.

[0033] S3. Based on the adjustment range and the thermal satisfaction factor, combined with the current spiral channel structure path length and the maximum allowable length of the spiral channel structure design, calculate the final structural adjustment amount, and dynamically adjust the path length of the spiral channel based on the final structural adjustment amount. This step is the "Structure Execution Module," whose core task is to process the adjustment instructions output by the Structure Adjustment Derivation Module. and thermal satisfaction factor This is translated into structurally executable actions, thereby dynamically adjusting the spiral channel path length to adapt to the thermal efficiency target. In the previous steps, a thermal efficiency identification was established... and Further based on water flow With target temperature rise Calculate , and by Derive the structural adjustment range .

[0034] To complete the structure's execution actions, real-time structural status feedback variables are also required: This indicates the current structural path length, derived from a displacement sensor, such as an encoder or magnetoresistive strip; This represents the maximum allowable path variation range in the structural design (e.g., 180 mm), and is a fixed parameter of the system. , representing the structure-thermal response inertia factor, is an experimentally calibrated value used to characterize the delay from structural change to thermal state change.

[0035] in, and It is used to determine the location of a target. These are parameters required to construct the inertia compensation term. They are not introduced. , Variables that have been used in the previous module but not in this step should be removed to avoid redundancy.

[0036] The primary objective of this step is to determine the path length of the target structure. According to the structural adjustment range command First, we obtain the basic target length: ; in Real-time feedback from structural sensors This is a structural adjustment ratio derived based on the current thermal efficiency situation. This represents the maximum extendable length of the structure.

[0037] However, in real-world systems, there is a delay in thermal response: even after the structure has undergone physical adjustment, the change in water temperature still takes some time to manifest. To compensate for this, a thermal inertia compensation term is introduced. Superimpose it onto In the middle, the complete structural target length is formed: ; Compensation The definition is as follows: ; This indicates an empirical compensation coefficient (e.g., 0.2), determined through engineering commissioning. This represents the structural thermal satisfaction factor; the smaller the factor, the more mismatched the structure is, and the greater the compensation is needed. This represents thermal response inertia; the larger the value, the slower the temperature response, and the more it needs to be increased to reduce structural overshoot. This represents a microconstant (such as 0.01) to prevent division by zero errors. The design aims to enable feedforward regulation of the system under conditions of thermal response hysteresis. For example, if , , , ,but mm, which is an additional 3.18 mm on top of the adjustment to offset temperature lag.

[0038] The system then calculates the target length based on the results. However, all changes should not be implemented immediately to avoid frequent structural fluctuations due to small thermal disturbances. Therefore, a thermal satisfaction suppression coefficient is introduced to control the final structural adjustment amount. : ; Indicates the response suppression coefficient (e.g.) This reflects the degree of conservatism in the system; This represents the structural thermal satisfaction factor, when the structure is sufficiently matched ( When the index is large, the index factor approaches 0, weakening the adjustment. This represents the final structural adjustment amount, which is the explicit output variable of this step and will be mapped to the actuator control amount.

[0039] This design ensures that the structure only experiences a significant decrease in thermal performance. It performs large changes when the temperature is low, but automatically suppresses changes when the thermal condition is basically met, thereby reducing fatigue and system energy consumption.

[0040] final, The instructions will be converted into specific action commands based on the type of drive mechanism, which includes the following steps: If a motor-driven slide rail system is used, it is converted to a number of steps. ; If shape memory alloy wire is used, it is converted into current pulses. Control the length; Control signals are sent in real time and used Perform a closed-loop verification.

[0041] S4. Calculate the target power of the water purifier's heater based on the adjustment length and thermal satisfaction factor of the spiral water channel structure, and calculate the final water purification heating power based on the target power of the heater and the preset basic power. This step, the "Heating Power Setting Module," aims to adjust the structural length based on the output of the structural execution module. With thermal satisfaction factor Determine the dynamic target power of the heater. .

[0042] This step is at the end of the entire system control chain, and is the final link in achieving the integrated "structure-thermal-energy" control closed loop. In the preceding steps, This characterizes the degree to which the current structure adapts to thermal demands. This reflects the physical adjustments the structure makes in response to a decrease in thermal efficiency. Therefore, It should not be based solely on preset parameters such as target temperature rise or traffic Decisions should be made, but dynamic adaptations should be adopted. This step involves designing an innovative dynamic power correction mechanism based on the redundancy states and structural behavior of the system, thereby avoiding the contradiction of "the structure is adjusted but the heat is insufficient" or "the heat increases but the structure does not keep up".

[0043] To enable the heater to respond in tandem with structural changes and thermal state, a thermal-structural coupling sensing mechanism is designed to output the final heating power. The mechanism consists of two parts: ① Structural adjustment response weighting function ① Used to estimate whether the system needs additional power; ② Heating power correction model, based on Output the dynamically adjusted power setting value.

[0044] First, construct the structure-adjusted response weight function. Instead of using a simple proportional relationship, a multi-factor suppression function is introduced based on the structural adjustment amplitude, the degree of thermal dissatisfaction, and the structural energy inertia exponent: ; The first indicator shows that the smaller the adjustment range, the higher the heat satisfaction. The first term approaches 1; the second term is a creatively introduced "nonlinear energy hysteresis index compensation term," which indicates that when the structure undergoes drastic adjustments and the thermal satisfaction is low, The system needs to be replenished with energy in advance as needed. The adjustment coefficient for the compensation term (e.g., 0.5–1.0) is obtained through system debugging. For example: If mm, mm, , Then the first item is The second item is ,final .

[0045] Next, according to Correct the current power setting. The system sets a base power. This value can be based on and The historical proportions are determined (not implemented in this module). Then it is defined as: ; in, The energy regulation sensitivity coefficient (e.g., 0.3–0.5); The nonlinear term for power correction makes the system in Increase the power compensation level when the power is low, but avoid linear bursts.

[0046] Example: if W, , ,but , ,final W indicates that the system has small adjustments and a good thermal state, requiring only slight power compensation; while if the structural adjustments are drastic, Low (e.g.) If so, the compensation will reach nearly 50% or more.

[0047] This mechanism reflects: For intense structural regulation behavior ( Large), active power compensation; for poor thermal condition ( (Small), power response is timely; for scenarios where "the structure has changed but the heat has not caught up", power is added in advance to eliminate inertia.

[0048] In one or more embodiments, such as Figure 2 As shown, a water purification and heating system based on a spiral water channel structure is disclosed, the system comprising: The thermal efficiency status identification module is used to calculate the current actual heating capacity and the current thermal efficiency normalization ratio of the water purifier based on the internal data of the water purifier. The structural adjustment demand derivation module is used to collect real-time water flow and preset target temperature rise, and calculate the heat satisfaction factor in combination with the current thermal efficiency of the water purifier. The heat satisfaction factor is used to reflect the potential side effects of structural adjustment on the heating device. Based on the heat satisfaction factor, the adjustment range of the current water channel structure is calculated. The water channel structure is a spiral structure and the water channel structure is made of food-grade steel. The structural execution module calculates the final structural adjustment amount based on the adjustment range and the thermal satisfaction factor, combined with the current spiral channel structure path length and the maximum allowable length of the spiral channel structure design, and dynamically adjusts the path length of the spiral channel based on the final structural adjustment amount. The heating power setting module is used to calculate the target power of the water purifier's heater based on the adjustment length and thermal satisfaction factor of the spiral water channel structure, and to calculate the final water purification heating power based on the target heater power combined with a preset base power. It is worth noting that the specific workflow of the water purification heating system based on a spiral water channel structure provided in this embodiment is the same as that of the water purification heating method based on a spiral water channel structure described in the above embodiment, and will not be repeated here.

[0049] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.

When the adjustment amplitude of the spiral water channel structure is less than the preset threshold, only slight power compensation is performed; if the adjustment amplitude of the spiral water channel structure is greater than the preset threshold, the power compensation amplitude will be greater than 50%.

9. A system for implementing the water purification and heating method based on a spiral waterway structure as described in claim 1, characterized in that, include: The thermal efficiency status identification module is used to construct a thermal efficiency model based on the internal data of the water purifier to calculate the actual heating capacity and the current thermal efficiency normalization ratio of the water purifier. The internal data includes inlet water temperature, outlet water temperature, heating power, and water flow rate. The current thermal efficiency normalization ratio is calculated based on the actual heating capacity and reference thermal efficiency value of the water purifier. The thermal efficiency model is constructed by normalizing the actual temperature rise and unit energy consumption. The thermal efficiency model quantifies the ratio of the actual temperature rise capacity of the actual water body to the input power at a unit flow rate. The thermal efficiency model is dynamically updated by using a short-time window sliding mean method to reduce the calculation error caused by a single disturbance and output the true heating capacity of the water purifier, which is used to evaluate whether the heating capacity has decreased due to structural degradation or scaling. The structural adjustment demand derivation module is used to collect real-time water flow and preset target temperature rise, and calculate the heat satisfaction factor in combination with the actual heating capacity of the current water purifier. The heat satisfaction factor is used to reflect the potential side effects of structural adjustment on the heating device. Based on the heat satisfaction factor, the adjustment range of the current water channel structure is calculated. The water channel structure is a spiral structure. The structure execution module is used to calculate the final structure adjustment amount based on the adjustment range and the thermal satisfaction factor, combined with the current spiral channel structure path length and the maximum length allowed by the spiral channel structure design, and to dynamically adjust the path length of the spiral channel based on the final structure adjustment amount. The heating power setting module is used to calculate the target power of the water purifier's heater based on the adjustment length and thermal satisfaction factor of the spiral water channel structure, and to calculate the final water purification heating power based on the target power of the heater and the preset base power.
