[0051] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0052] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0053] The main solution of this application embodiment is: to obtain the current ambient temperature range; to obtain the current set temperature; and to calculate the hot water volume display parameters corresponding to the water heater based on the current ambient temperature range and the set temperature, so as to display the hot water volume.

[0054] Because current water heaters often fail to display a full tank of hot water after reaching the set temperature and shutting off, the displayed hot water volume is inaccurate, sometimes showing less than the actual amount. This leads to user misjudgment, with users experiencing either no hot water available during use or, after using some hot water, the displayed volume being too low to use (e.g., for showering), resulting in a poor user experience. Furthermore, if the machine is turned on while the hot water tank is still full after some use, users, especially with heat pump water heaters (where the energy efficiency ratio increases with lower water temperature), may mistakenly believe the machine is energy-inefficient and turn it on even when the tank is still full, leading to complaints about low actual energy efficiency.

[0055] This application provides a solution that, by setting multiple temperature ranges, calculates the corresponding water tank temperature based on the current ambient temperature range, thereby determining specific display parameters and improving the accuracy of the remaining hot water volume display in the water tank.

[0056] The executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, such as a water heater hot water volume display device. The following description uses a water heater hot water volume display device as an example to illustrate this embodiment and the subsequent embodiments.

[0057] Based on this, this application provides a method for displaying the hot water volume of a water heater. Referring to Figure 1, Figure 1 is a flowchart of the first embodiment of the method for displaying the hot water volume of a water heater according to this application.

[0058] In this embodiment, the method for displaying the hot water volume of the water heater includes steps S10 to S30:

[0059] Step S10: Obtain the current ambient temperature range.

[0060] The current ambient temperature can be measured by an ambient temperature sensor set up outdoors or indoors. The current ambient temperature range can be predefined, as shown in Table 1 below. Table 1 is a table showing the relationship between ambient temperature and ambient temperature range.

[0061] Table 1

[0062] Ambient temperature \(T\), Ambient temperature range \(T\geq T_1\), range \(A_1\); \(T_1>T\geq T_2\), range \(A_2\); \(T_2>T\geq T_3\), range \(B\); \(T_5>T\geq T_4\), range \(C_1\); \(T_4>T\geq T_5\), range \(C_2\); \(T_5>T\geq T_6\), range \(C_3\); \(T < T_6\), range \(C_4\)

[0063] \(T_1>T_2>T_3>T_4>T_5>T_6\). When the ambient temperature is different, the corresponding ambient temperature range is also different. For example, when the ambient temperature is greater than or equal to \(T_1\), the ambient temperature range at this time is range \(A_1\).

[0064] In a specific implementation, the historical ambient temperature can be obtained, the change trend of the current ambient temperature can be obtained based on the historical ambient temperature, and the current ambient temperature range where the current ambient temperature is located can be determined according to the change trend and the current ambient temperature. As shown in Figure 2, Figure 2 is a schematic diagram of the relationship between the current ambient temperature and the current ambient temperature range where the current ambient temperature is located. For example, if the change trend is an upward trend, then \(T_1 = 40^{\circ}C\), \(T_2 = 32^{\circ}C\), \(T_3 = 20^{\circ}C\), \(T_4 = 8^{\circ}C\), \(T_5=-2^{\circ}C\), \(T_6 = -8^{\circ}C\). When the current ambient temperature is greater than or equal to \(40^{\circ}C\), the ambient temperature range is \(A_1\). When the current ambient temperature is in \([32, 40)\), the corresponding ambient temperature range is range \(A_2\). When the current ambient temperature is in \([20, 32)\), the corresponding ambient temperature range is range \(A_3\). When the current ambient temperature is in \([8, 20)\), the corresponding ambient temperature range is range \(A_4\). When the current ambient temperature is in \([-2, 8)\), the corresponding ambient temperature range is range \(A_5\). When the current ambient temperature is in \([-8, -2)\), the corresponding ambient temperature range is range \(A_6\).

[0065] If the change trend is a downward trend, then \(T_1 = 38^{\circ}C\), \(T_2 = 30^{\circ}C\), \(T_3 = 18^{\circ}C\), \(T_4 = 6^{\circ}C\), \(T_5=-4^{\circ}C\), \(T_6 = -10^{\circ}C\). When the current ambient temperature is greater than or equal to \(38^{\circ}C\), the ambient temperature range is \(A_1\). When the current ambient temperature is in \([30, 38)\), the corresponding ambient temperature range is range \(A_2\). When the current ambient temperature is in \([18, 30)\), the corresponding ambient temperature range is range \(A_3\). When the current ambient temperature is in \([6, 18)\), the corresponding ambient temperature range is range \(A_4\). When the current ambient temperature is in \([-4, 6)\), the corresponding ambient temperature range is range \(A_5\). When the current ambient temperature is in \([-10, -4)\), the corresponding ambient temperature range is range \(A_6\).

[0066] Step S20: Obtain the current set temperature.

[0067] The current set temperature is the temperature set by the user. For example, if the user sets the heating temperature of the water heater to \(50^{\circ}C\), then the current set temperature is \(50^{\circ}C\). The current set temperature can be adjusted according to the current ambient temperature. The lower the ambient temperature, the higher the set temperature set by the user.

[0068] Step S30: Calculate the hot water volume display parameters corresponding to the water heater based on the current ambient temperature range and the set temperature, and then display the hot water volume.

[0069] In practice, different ambient temperature ranges require different calculation methods for hot water volume display parameters. The specific calculation method can be determined based on the current ambient temperature range. This method then uses the set temperature to calculate the corresponding hot water volume display parameters for the water heater, which are then displayed on the water heater. The hot water volume display parameters can be a percentage of the hot water volume or displayed according to a set number of bars. For example, if the hot water volume is full, the hot water volume display parameter will be 100% or show a full bar; if the hot water volume is 20% of the tank's capacity, the hot water volume display parameter will be 20% or show one bar.

[0070] In practice, the maximum water temperature that the heat pump can heat can be determined based on the current ambient temperature. The maximum water temperature that the heat pump can heat varies under different ambient temperatures. For example, the lower the ambient temperature, the higher the maximum water temperature that the heat pump can heat.

[0071] As shown in Figure 3, the water tank of the water heater includes an outer shell, a foaming layer, an inlet pipe, an outlet pipe, and an inner tank. Two temperature sensors are installed on the water tank, one above the water tank and the other below the water tank, to measure the temperature T5U above the water tank and the temperature T5L below the water tank, respectively.

[0072] This embodiment provides a method for displaying hot water volume in a water heater. It involves obtaining the current ambient temperature range and the current set temperature; calculating the corresponding hot water volume display parameters based on the current ambient temperature range and the set temperature; and then displaying the hot water volume. By determining a specific range based on the current ambient temperature, and adjusting the hot water volume display parameters according to the user-set temperature and the corresponding ambient temperature range, the remaining hot water volume of the water heater can be accurately calculated. This accurate calculation can be performed without additional costs, resulting in more accurate hot water display on the water heater and improving the user experience.

[0073] Based on the first embodiment of this application, in the second embodiment of this application, the content that is the same as or similar to that in the first embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 4; step S20 includes steps S201 to S202:

[0074] Step S201: Determine the target heating temperature based on the current ambient temperature.

[0075] The target heating temperature is Tstop, which is the highest water temperature that the heat pump can heat. The highest water temperature that the heat pump can heat is not a fixed value. The target heating temperature changes continuously according to the current ambient temperature. For example, if the current ambient temperature is in the range of 40 to 46 degrees Celsius, the target heating temperature is 45 degrees Celsius. If the current ambient temperature is in the range of -2 to 8 degrees Celsius, the target heating temperature is 60 degrees Celsius.

[0076] In one embodiment, as shown in FIG10, step S201 may include steps A21-A22:

[0077] Step A21: Obtain historical ambient temperatures and determine the trend of the current ambient temperature based on the historical ambient temperatures.

[0078] Historical ambient temperatures can be ambient temperatures prior to the current ambient temperature. For example, the ambient temperature 30 minutes before the current ambient temperature can be used as historical ambient temperatures, and the trend of the current ambient temperature can be determined based on historical ambient temperatures. The trend of the current ambient temperature can be upward or downward.

[0079] Step A22: Determine the target heating temperature based on the changing trend and the current ambient temperature.

[0080] In practice, the target heating temperature may be the same or different when the changing trend is different. For example, if the ambient temperature is on an upward trend and the current ambient temperature is 41 degrees Celsius, the target heating temperature is determined to be 45 degrees Celsius. If the ambient temperature is on a downward trend and the current ambient temperature is 41 degrees Celsius, the target heating temperature is determined to be 45 degrees Celsius.

[0081] Figure 5 illustrates the relationship between the current ambient temperature and the target heating temperature. For example, if the trend is upward, and the current ambient temperature is between 40 and 46 degrees Celsius, the target heating temperature is 45 degrees Celsius; if the current ambient temperature is between 32 and 40 degrees Celsius, the target heating temperature is 52 degrees Celsius; if the current ambient temperature is between 8 and 32 degrees Celsius, the target heating temperature is 55 degrees Celsius; if the current ambient temperature is between -2 and 8 degrees Celsius, the target heating temperature is 60 degrees Celsius; if the current ambient temperature is between -8 and -2 degrees Celsius, the target heating temperature is 59 degrees Celsius; if the current ambient temperature is between -11 and -8 degrees Celsius, the target heating temperature is 50 degrees Celsius; if the current ambient temperature is between -16 and -11 degrees Celsius, the target heating temperature is 45 degrees Celsius; and if the current ambient temperature is between -20 and -16 degrees Celsius, the target heating temperature is 43 degrees Celsius.

[0082] If the trend is downward, and the current ambient temperature is between 45 and 39 degrees Celsius, the target heating temperature is 45 degrees Celsius; if the current ambient temperature is between 31 and 39 degrees Celsius, the target heating temperature is 52 degrees Celsius; if the current ambient temperature is between 7 and 31 degrees Celsius, the target heating temperature is 55 degrees Celsius; if the current ambient temperature is between -3 and 7 degrees Celsius, the target heating temperature is 60 degrees Celsius; if the current ambient temperature is between -9 and -3 degrees Celsius, the target heating temperature is 59 degrees Celsius; if the current ambient temperature is between -12 and -9 degrees Celsius, the target heating temperature is 50 degrees Celsius; if the current ambient temperature is between -17 and -12 degrees Celsius, the target heating temperature is 45 degrees Celsius; if the current ambient temperature is between -21 and -17 degrees Celsius, the target heating temperature is 43 degrees Celsius.

[0083] Step S202: Determine the hot water volume display parameters corresponding to the water heater based on the current ambient temperature range, the target heating temperature, and the set temperature.

[0084] The water heater can calculate the corresponding hot water volume display parameters based on the current ambient temperature range, target heating temperature, and set temperature.

[0085] In practice, the set temperature can be compared with the target heating temperature to determine the hot water volume display parameters corresponding to the current ambient temperature range.

[0086] This embodiment determines the target heating temperature based on the current ambient temperature; and determines the corresponding hot water volume display parameters of the water heater based on the current ambient temperature range, the target heating temperature, and the set temperature. By determining the target heating temperature based on the current ambient temperature, this method ensures that the hot water temperature output by the water heater more accurately meets the user's needs and is unaffected by changes in the external ambient temperature. This not only improves the user experience but also avoids safety hazards or energy waste caused by excessively high or low temperatures. Based on the current ambient temperature range, the target heating temperature, and the user-set temperature, the hot water volume display parameters provided by the water heater are dynamically adjusted. This intelligent adjustment mechanism enables the water heater to operate more efficiently, that is, while meeting the user's hot water needs, it reduces unnecessary heating processes, thereby achieving energy saving and emission reduction effects.

[0087] Based on the second embodiment of this application, in the third embodiment of this application, the content that is the same as or similar to that in the second embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 6, step S202 includes steps B21~B22:

[0088] Step B21: Determine the target calculation strategy based on the current ambient temperature range.

[0089] The calculation method varies depending on the current ambient temperature range. For example, if the current ambient temperature range is A1, the target calculation strategy is S1. If the current ambient temperature range is A2, the target calculation strategy is S2. Therefore, the correspondence between ambient temperature ranges and calculation strategies can be established in advance, and the target calculation strategy can be determined by the correspondence and the current ambient temperature range.

[0090] Step B22: Calculate the hot water volume display parameters corresponding to the water heater using the target calculation strategy, the target heating temperature, and the set temperature.

[0091] In practice, the hot water volume display parameters of the water heater within the current ambient temperature range can be calculated based on the target calculation strategy, target heating temperature, and set temperature.

[0092] For example, the target calculation strategy can be different depending on the current ambient temperature range, and the corresponding calculation formula will be different. Therefore, the hot water volume display parameters of the water heater can be calculated by setting the temperature and the target heating temperature and using the corresponding calculation formula.

[0093] The target calculation strategy is determined based on the current ambient temperature range; the corresponding hot water volume display parameters of the water heater are calculated using the target calculation strategy, the target heating temperature, and the set temperature. By determining the target calculation strategy based on the current ambient temperature range, this method allows the water heater to more flexibly respond to usage needs under different environmental conditions. Different ambient temperature ranges may require different heating strategies to achieve the optimal hot water supply effect. This method ensures the adaptability and flexibility of the system, improving the applicability of the equipment in various environments.

[0094] Based on the second embodiment of this application, in the fourth embodiment of this application, the content that is the same as or similar to that in the second embodiment described above can be referred to the above description and will not be repeated hereafter. Based on this, please refer to Figure 7, step S202 includes steps C21~C22:

[0095] Step C21: Calculate multiple temperature thresholds based on the current ambient temperature range, the target heating temperature, and the set temperature.

[0096] Multiple temperature thresholds can be calculated based on the current ambient temperature range, target heating temperature, and set temperature. The temperature thresholds are comparative temperature values ​​of the water tank upper temperature and water tank lower temperature under different conditions.

[0097] For example, if the current ambient temperature range is A1, the set temperature can be compared with the target heating temperature to calculate multiple temperature thresholds. These thresholds, from largest to smallest, can include T5U_A, T5U_B, T5U_C, T5U_D, and T5U_M, and may also include T5L_E, T5L_F, T5L_G, and T5L_H. The set temperature is Ts, and the target heating temperature is Tstop.

[0098] A1 interval:

[0099] a. When the set temperature Ts ≥ the target heating temperature Tstop+1 (e.g., 46), T5U_A = Tstop-3 (e.g., 42); otherwise, T5U_A = Ts-3.

[0100] b. When the set temperature Ts≥46, T5U_B=T5U_A-1; otherwise, T5U_B=T5U_A+1.

[0101] c. When the set temperature Ts ≥ 50, T5U_C = T5U_B - 3; when 50 > set temperature Ts ≥ 44, T5U_C = T5U_B - 3; when 44 > Ts ≥ 40, T5U_C = T5U_B - 2; when 40 > Ts, T5U_C = T5U_B - 1.

[0102] d. When Ts≥51, T5U_D=T5U_C-3; when 51>Ts≥45, T5U_D=T5U_C-3; when 45>Ts≥43, T5U_D=T5U_C-3; when 43>Ts≥40, T5U_D=T5U_C-2; when 40>Ts, T5U_D=T5U_C-1.

[0103] e, T5L_E=T5U_D;

[0104] f、T5L_F=T5U_A;

[0105] g, T5L_G = T5U_C-1;

[0106] h, T5L_H = T5U_D-1;

[0107] m. When the set temperature Ts≥45, T5U_M=T5U_D-2; otherwise, T5U_M=T5U_D-1.

[0108] In the A1 range, the corresponding ambient temperature is relatively high. At this time, the target heating temperature may be 45 degrees Celsius. If the set temperature is greater than or equal to 46 degrees Celsius, then T5U_A = Tstop - 3 = 45 - 3 = 42. If the set temperature is less than 46 degrees Celsius, then T5U_A = set temperature - 3. If the set temperature is greater than or equal to 46 degrees Celsius, then T5U_A is obtained. T5U_B can be calculated based on T5U_A. Then, based on the relationship between the set temperature and the temperature constant, T5U_C, T5U_D, T5U_M, T5L_E, T5L_F, T5L_G, and T5L_H can be further calculated to obtain multiple temperature thresholds.

[0109] Similarly, when the current ambient temperature is in the A2 range, the calculation process is as follows:

[0110] a. When Ts≥Tstop+1 (e.g., 54), T5U_A= Tstop-4 (e.g., 49); otherwise, T5U_A=Ts-3.

[0111] b. When Ts≥47, T5U_B=T5U_A-2; otherwise, T5U_B=T5U_A-1.

[0112] c. When Ts≥50, T5U_C=T5U_B-4; when 50>Ts≥44, T5U_C=T5U_B-3; when 44>Ts≥40, T5U_C=T5U_B-2; when 40>Ts, T5U_C=T5U_B-1.

[0113] d. When Ts≥51, T5U_D=T5U_C-5;

[0114] When 51>Ts≥46, T5U_D=T5U_C-4; when 46>Ts≥43, T5U_D=T5U_C-3; when 43>Ts≥40, T5U_D=T5U_C-2; when 40>Ts, T5U_D=T5U_C-1.

[0115] e, T5L_E=T5U_D;

[0116] f、T5L_F=T5U_A;

[0117] g, T5L_G = T5U_C-1;

[0118] h, T5L_H = T5U_D-1;

[0119] m. When Ts≥45, T5U_M=T5U_D-2; otherwise, T5U_M=T5U_D-1.

[0120] When the current ambient temperature is in range B, the calculation process is as follows:

[0121] a. When Ts≥Tstop+1 (e.g., 56), T5U_A= Tstop-2 (e.g., 53); otherwise, T5U_A=Ts-2.

[0122] b. When Ts≥47, T5U_B=T5U_A-2; otherwise, T5U_B=T5U_A-1.

[0123] c. When Ts≥50, T5U_C=T5U_B-4; when 50>Ts≥44, T5U_C=T5U_B-3; when 44>Ts≥40, T5U_C=T5U_B-2; when 40>Ts, T5U_C=T5U_B-2.

[0124] d. When Ts≥54, T5U_D=T5U_C-6; when 54>Ts≥51, T5U_D=T5U_C-5; when 51>Ts≥46, T5U_D=T5U_C-4; when 46>Ts≥43, T5U_D=T5U_C-3; when 43>Ts, T5U_D=T5U_C-2.

[0125] e, T5L_E=T5U_D;

[0126] f、T5L_F=T5U_A;

[0170] Step C22: Determine the hot water volume display parameters corresponding to the water heater through multiple temperature thresholds.

[0171] After obtaining multiple temperature thresholds, the temperature thresholds that the water tank temperature is close to can be determined, thereby determining the corresponding hot water volume display parameters for the water heater.

[0172] In one embodiment, step C22 may include: acquiring a first temperature and a second temperature of the water tank, wherein the first temperature is greater than the second temperature; and determining a hot water volume display parameter corresponding to the water heater based on the first temperature and / or the second temperature and a plurality of temperature thresholds.

[0173] The first temperature of the water tank is the temperature at the top of the water tank, and the second temperature of the water tank is the temperature at the bottom of the water tank. The hot water volume display parameters corresponding to the water heater can be determined based on the temperature at the top of the water tank (T5U), the temperature at the bottom of the water tank (T5L), and multiple parameters among the multiple temperature thresholds.

[0174] In one embodiment, the step of determining the hot water volume display parameter corresponding to the water heater based on the first temperature of the water tank and / or the second temperature of the water tank, and a plurality of temperature thresholds includes:

[0175] Multiple temperature threshold ranges are determined based on the multiple temperature thresholds described above;

[0176] Determine the target temperature threshold range in which the first temperature and / or the second temperature of the water tank fall within the plurality of temperature threshold ranges;

[0177] Determine the hot water volume display parameters of the water heater corresponding to the target temperature threshold range.

[0178] Multiple temperature threshold ranges can be determined based on multiple temperature thresholds, specifically including: greater than or equal to T5U_A, [T5U_B, T5U_A), [T5U_C, T5U_B), [T5U_D, T5U_C), [T5U_M, T5U_D), less than T5U_M, greater than or equal to T5L_E, greater than or equal to T5L_F, less than T5L_E, less than T5L_F, greater than or equal to T5L_G, less than T5L_G, greater than or equal to T5L_H, and less than T5L_H.

[0179] The first and / or second temperatures of the water tank can be compared with multiple temperature thresholds to determine the target temperature threshold range within which the first and / or second temperatures of the water tank fall. For example, the target temperature threshold range can be determined based on the first temperature of the water tank or based on both the first and second temperatures of the water tank.

[0180] In practical implementation, the corresponding hot water volume display parameters of the water heater can be determined according to the target temperature threshold range, as shown in Table 2 below. Table 2 is a table showing the relationship between the temperature threshold range and the hot water volume display parameters:

[0181] Table 2

[0182] T5U≥T5U_AT5L≥T5L_E5 (100%) T5U_A>T5U≥T5U_BT5L≥T5L_F5 (100%) T5U≥T5U_AT5L<T5L_E4 (80%) T5U_A>T5U≥T5U_BT5L<T5L_F4 (80%) T5U_B>T5U≥T5U_CT5L≥T5L_G 4 grids (80%) T5U_B > T5U ≥ T5U_CT5L < T5L_G 3 grids (60%) T5U_C > T5U ≥ T5U_DT5L ≥ T5L_H 3 grids (60%) T5U_C > T5U ≥ T5U_DT5L < T5L_H 2 grids (40%) T5U_D > T5U ≥ T5U_M / 1 grid (20%) T5U < T5U_M / 0 grids (0%)

[0183] For example, if the target temperature threshold range determined based on the first temperature and the second temperature of the water tank is T5U_B>T5U≥T5U_C and T5L<T5L_G, then the corresponding hot water volume display parameter of the water heater is to display 4 bars (80%).

[0184] In practice, the remaining hot water volume can also be calculated based on the target temperature threshold range. For example, the remaining hot water volume corresponding to different temperature threshold ranges can be set in advance, thereby determining the specific hot water volume display parameters based on the remaining hot water volume.

[0185] This embodiment calculates multiple temperature thresholds based on the current ambient temperature range, the target heating temperature, and the set temperature; and determines the corresponding hot water volume display parameters of the water heater using these multiple temperature thresholds. By calculating multiple temperature thresholds based on the current ambient temperature range, the target heating temperature, and the user-set temperature, precise control of the water heater heating process can be achieved. This method of setting multiple temperature thresholds allows the system to adopt different control strategies at different heating stages, improving the accuracy and response speed of temperature control. This results in the displayed hot water volume more accurately representing the usable hot water volume.
