[0042] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0043] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0044] In this embodiment of the disclosure, the collection, storage, use, processing, transmission, provision, and disclosure of user personal information comply with relevant laws and regulations and do not violate public order and good morals.

[0045] The following describes a method for determining the heating power of a water-using device according to an embodiment of this disclosure. For example... Figure 1 As shown, the water-using equipment can be any device with a heating function, such as a water purifier or a water heater. The water-using equipment includes a first heating component 11 and a second heating component 12, which are connected to each other. The first heating component 11 is connected to the water inlet 13 of the water-using equipment. The hot water heated by the first heating component 11 and the second heating component 12 can be directly output from the hot water outlet 14, or connected to other components of the water-using equipment, such as a filter component, for filtration. In this embodiment, the use of the heated water is not restricted in much way, and the specific choice is made according to the actual situation.

[0046] In one embodiment, the selection of the first heating component and the second heating component can be that both are heating elements, both are compressors, or one heating component is a compressor and the other heating component is a heating element.

[0047] In this embodiment, the first heating component is preferably a compressor, and the second heating component is preferably a heating element, but this is not the only option; the choice depends on the specific application scenario. The purpose of this compressor and heating element configuration is that the compressor provides higher heating efficiency, typically reaching 400%, but also consumes more energy. While the heating element has a lower heating efficiency, typically only 95% (theoretically 100%), it consumes less energy. Therefore, by configuring the compressor and heating element as a two-stage heating circuit and adjusting their heating power, a balance between heating efficiency and energy consumption is found, satisfying the user's hot water needs as much as possible without wasting energy.

[0048] Figure 2 This is a flowchart illustrating a method for determining the heating power of a water-using device according to an embodiment of this disclosure. This specification provides the method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive methods, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or server product execution, the method can be executed sequentially according to the embodiments or drawings, or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 1 As shown, the method may include:

[0049] S201. Obtain the target water temperature and inlet water temperature of the water-using equipment.

[0050] The target water temperature is set by the user according to their hot water needs. If the user does not set it, the target water temperature can be determined by the temperature set in the factory settings. The inlet water temperature is generally obtained by the first temperature sensor set at the inlet of the water-using equipment.

[0051] S202. Based on the target water temperature and the inlet water temperature, determine the inlet water flow rate under the total power constraint, and heat the water with the first heating component at the first heating power and the second heating component at the second heating power.

[0052] Since the target water temperature and the inlet water temperature are different, in order to find the power balance between the first heating component and the second heating component more accurately, and to find the optimal solution to reduce energy consumption and improve heating efficiency, this embodiment needs to first determine the inlet water flow rate, the first heating power and the second heating power under the total power constraint, and then make adjustments step by step.

[0053] In one embodiment, the total power constraint is usually determined based on the rated maximum power of the water-using equipment. Generally, the rated maximum power of household water-using equipment is 3200W or 2200W. The rated maximum power is usually set during the production process according to the power consumption scenario. The rated maximum power of commercial water-using equipment is more than 3200W, but it will not be elaborated on in this embodiment. The specific choice is based on the actual situation.

[0054] After determining the rated maximum power, the heating capacity of water can be calculated using the formula... P is heat (in this embodiment, power is used for ease of calculation), m is mass, c is specific heat capacity, ΔT is temperature change, and step S202 calculates the influent flow rate:

[0055]

[0056] in, This refers to the inlet water flow rate. This is the rated maximum power. The density of water, The specific heat capacity of water, For the target water temperature, For the inlet water temperature, To improve the heat exchange efficiency of the heating components, the specific values ​​of water's specific heat capacity and density can be set according to the actual situation, and can be selected based on the specific circumstances.

[0057] In one embodiment, the first heating power is determined based on the intermediate water temperature and the inlet water temperature of the first heating component, and the second heating power is determined based on the target water temperature and the intermediate water temperature of the second heating component, wherein the intermediate water temperature is the temperature that the first heating component can reach after heating the water.

[0058] Specifically, the first heating power is calculated based on the formula for the heat of water:

[0059]

[0060] in, The first heating power, This is the intermediate water temperature. For the inlet water temperature, The specific heat capacity of water (preferably 4.18 kJ / (kg·℃)). The density of water (1000 kg / m³). This refers to the inlet water flow rate. The heat exchange efficiency of the first heating component can be adjusted based on the specific heat capacity and density of water, which can be selected according to actual conditions.

[0061] Specifically, the second heating power is calculated based on the formula for the heating capacity of water:

[0062]

[0063] in, This is the second heating power. For the target water temperature, This is the intermediate water temperature. The specific heat capacity of water (preferably 4.18 kJ / (kg·℃)). The density of water (1000 kg / m³). This refers to the inlet water flow rate. The heat exchange efficiency of the second heating element.

[0064] It is important to emphasize that, in order to meet the total power constraint, , where P is the maximum rated power of the water-using equipment.

[0065] In step S202, during the determination of the first and second heating powers, the intermediate water temperature is initially set to equal the inlet water temperature. Theoretically, in this case, water heating relies on the second heating component, resulting in minimal heating energy consumption. However, relying solely on the second heating component is insufficient to heat a large flow of water in a short time. Therefore, the heating power of the first heating component needs to be gradually increased until the user's needs are met. See the subsequent embodiments for details. Furthermore, it is important to emphasize that the first and second heating powers determined in step S202 are not the final power of the first and second heating components of the water-using equipment.

[0066] S203. Adjust the inlet water flow rate, the first heating power and the second heating power according to the outlet water temperature of the water-using equipment until the outlet water temperature reaches the target water temperature.

[0067] The outlet water temperature is generally obtained by a second temperature sensor installed at the outlet of the second heating component.

[0068] In one embodiment, see Figure 3 Step S203 includes:

[0069] S2031. If the outlet water temperature does not reach the target water temperature, obtain the intermediate water temperature of the first heating component.

[0070] The intermediate water temperature is generally increased gradually with the number of measurements, and is initially set to be the same as the inlet water temperature. Typically, the outlet water temperature is measured every preset time interval to determine if it has reached the target temperature. If the outlet water temperature has not reached the target temperature, the intermediate water temperature is increased by 1-3℃, but this is not a fixed value; the specific value can be selected based on the actual situation.

[0071] S2032. Adjust the inlet water flow rate according to the inlet water temperature, outlet water temperature, and intermediate water temperature.

[0072] Specifically, the inlet water flow rate is calculated based on the formula for the heat of water heating:

[0073]

[0074] in, The adjusted inlet flow rate, This is the rated maximum power. The density of water, The specific heat capacity of water, For the target water temperature, For the inlet water temperature, This is the intermediate water temperature. The heat exchange efficiency of the first heating element. The heat exchange efficiency of the second heating element.

[0075] S2033. Adjust the first heating power of the first heating component according to the adjusted inlet water flow rate, intermediate water temperature, and inlet water temperature.

[0076] Specifically, the first heating power is calculated based on the formula for the heat of water:

[0077]

[0078] in, The adjusted first heating power, This is the intermediate water temperature. For the inlet water temperature, The density of water, The specific heat capacity of water, The adjusted inlet flow rate, The heat exchange efficiency of the first heating element.

[0079] S2034. Adjust the second heating power of the second heating component according to the adjusted inlet water flow rate, intermediate water temperature, and target water temperature.

[0080] Specifically, the second heating power is calculated based on the formula for the heating capacity of water:

[0081]

[0082] in, The adjusted second heating power, For the target water temperature, This is the intermediate water temperature. The density of water, The specific heat capacity of water, The adjusted inlet flow rate, The heat exchange efficiency of the second heating element.

[0083] It is important to emphasize that, in order to meet the total power constraint, , where P is the maximum rated power of the water-using equipment.

[0084] For a specific example, assume the water purifier has an inlet water temperature of 20℃, a target water temperature of 90℃, an intermediate water temperature of 50℃, a maximum rated power of 3200W, and the first heating element is a compressor with a heat exchange efficiency of [missing information]. The second heating component is a heating element with a heat exchange efficiency of 0.95, a specific heat capacity of water of 4.18 kJ / (kg·℃), and a density of water of 1000 kg / m³.

[0085] The adjusted influent flow rate is calculated as follows:

[0086]

[0087] In contrast, existing technologies that use only one heating element typically have a water flow rate of 0.62 L / min. The heating power determination method provided in this embodiment, compared with existing technologies, increases the flow rate that the water-using equipment can heat by 48.3%, significantly improving the heating efficiency of the water-using equipment and meeting the user's hot water needs.

[0088] In one embodiment, the method further includes:

[0089] Based on the target water temperature and the inlet water temperature, the adjusted inlet water flow rate, the first heating power, and the second heating power are stored in the database.

[0090] The database stores the adjusted inlet water flow rate, first heating power, and second heating power, using the target water temperature and inlet water temperature as index conditions. When the water-using equipment encounters a heating demand at the same inlet water temperature and target water temperature during operation, it can directly call the above parameters from the database to control the water-using equipment to perform heating.

[0091] In one embodiment, after step S201, the method includes:

[0092] Based on the inlet water temperature and the target water temperature, the matching inlet water flow rate, first heating power and second heating power are determined from the database, and the water-using equipment is controlled to heat the water with the inlet water flow rate, the first heating component with the first heating power and the second heating component with the second heating power.

[0093] The database can be found in the embodiments described above. When the water-using equipment encounters the same heating demand at the same inlet water temperature and target water temperature during operation, it can directly call the above parameters from the database to control the water-using equipment to heat, without the need for repeated heating.

[0094] In this embodiment of the present disclosure, by setting a two-stage heating circuit of a first heating component and a second heating component in the water-using equipment, on the one hand, when a user has a large demand for hot water, the water can be heated quickly by the two heating components; on the other hand, by distributing the power of the first heating component and the second heating component, the water heating process can be divided into two stages, thereby avoiding the energy waste caused by repeatedly heating the water through a single heating component, thus balancing the improvement of heating efficiency and the reduction of energy consumption.
