[0050] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0051] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] The terms "first", "second", "third", "fourth", etc. (if any) in the description and claims of the present invention and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein.

[0053] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0054] At present, some water heaters estimate and display the available hot water volume in segments by monitoring the water temperature at different depths inside the water tank. However, this method has limitations. The actual hot water volume of the water heater may change due to various factors, but this method cannot be dynamically adjusted to reflect these changes. This leads to a large deviation between the hot water volume displayed on the screen and the actual available hot water volume, affecting the user experience.

[0055] In view of this, an embodiment of the present application provides a method for displaying the amount of hot water in a water heater. First, the temperature thresholds corresponding to different hot water amount display levels in the water heater are determined according to the current water inlet temperature, the mixed water temperature and the inner tank volume of the water heater. Then, based on the actual inner tank temperature of the water heater and the above-mentioned temperature thresholds, the current hot water amount display level is determined, and the water heater is controlled to display the current hot water amount display level. In this way, when the water inlet temperature and the mixed water temperature change, the system can also automatically adjust the temperature thresholds of each level, so that the displayed hot water amount is closer to the actual situation, effectively reducing the deviation between the hot water amount display and the actual hot water amount, and improving the accuracy of the hot water amount display result, thereby improving the user experience.

[0056] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0057] Figure 1 Schematic diagram of the process of the method for displaying the amount of hot water in a water heater provided in an embodiment of the present application Figure 1 , taking the controller of the water heater as an example, Figure 1 As shown, the method for displaying the amount of hot water in a water heater provided in this embodiment includes the following steps:

[0058] S101, determining the current water inlet temperature and mixed water temperature of the water heater.

[0059] Among them, the water inlet temperature of the water heater refers to the temperature of the cold water entering the water heater, and the mixed water temperature refers to the actual water outlet temperature after the hot water and cold water are mixed.

[0060] For example, the inlet water temperature can be detected in real time by installing a temperature sensor on the water inlet pipe of the water heater, and the mixed water temperature can be calculated based on the real-time measured hot water temperature, cold water temperature and flow rate.

[0061] S102: Determine temperature thresholds corresponding to a plurality of hot water volume display levels according to the inlet water temperature, the mixed water temperature and the inner tank volume of the water heater.

[0062] Among them, the inner tank volume of the water heater refers to the maximum capacity of the inner tank of the water heater.

[0063] It is understandable that the water inlet temperature and mixing water temperature of the water heater will directly affect the amount of hot water that the water heater can provide. For example, in winter or cold areas, the water inlet temperature is low, and the water heater needs more energy to heat the water, so the actual amount of hot water available may be reduced. In summer, the water inlet temperature is higher, the heating efficiency is improved, and the amount of hot water available increases. If the hot water volume display of the water heater is not adjusted according to these temperature changes, the user may misjudge the remaining amount of hot water, resulting in inconvenience. In addition, if the user increases the mixing water temperature, more hot water needs to be mixed, thereby reducing the amount of hot water available. Conversely, lowering the mixing water temperature increases the amount of hot water available.

[0064] For example, when the inlet water temperature decreases, the temperature threshold is increased to prevent the system from overestimating the actual amount of hot water available; when the inlet water temperature increases, the temperature threshold is lowered to prevent the system from underestimating the actual amount of hot water available. When the mixed water temperature increases, the temperature threshold is increased to reflect the decrease in the actual amount of hot water available; when the mixed water temperature decreases, the temperature threshold is lowered to reflect the increase in the actual amount of hot water available. In this way, according to the changes in the inlet water temperature and the mixed water temperature, the temperature threshold of each segment is dynamically adjusted to ensure accurate display results and improve user experience.

[0065] S103: Determine the current hot water volume display level according to the current inner tank temperature of the water heater and the temperature threshold, and display the current hot water volume display level.

[0066] Among them, the temperature threshold can be multiple preset temperature thresholds, which are used to indicate different levels of hot water volume. If the current inner tank temperature of the water heater falls within one of the temperature threshold ranges, the hot water volume level corresponding to the range will be used as the current display level.

[0067] Optionally, the display panel area of ​​the water heater includes indicator lights equal to the number of the multiple hot water volume display segments, and displays the current hot water volume display segment, including: controlling a corresponding number of indicator lights to light up according to the current hot water volume display segment.

[0068] For example, the indicator light is an RGB light that can display colors and display red or orange where there is water, and blue where there is no water. If the water heater is not heating, the RGB light controls the indicator light to display red where there is water, and blue where there is no water, according to the current display segment, or displays all lights where there is water, and no lights where there is no water. If the water heater is heating, the RGB light lights up from right to left or from bottom to top to perform a heating animation, controlling one light to light up at intervals of 500ms, and then entering the full light state one by one.

[0069] The method for displaying the hot water quantity of a water heater provided in the present embodiment determines the current water inlet temperature and mixed water temperature of the water heater, determines the temperature thresholds corresponding to each of the multiple hot water quantity display segments according to the water inlet temperature, the mixed water temperature and the inner tank volume of the water heater, determines the current hot water quantity display segment according to the current inner tank temperature of the water heater and the temperature threshold, and displays the current hot water quantity display segment; the method realizes dynamic adjustment of the temperature threshold of each hot water quantity display segment of the water heater, reduces the deviation between the hot water quantity display segment and the actual hot water quantity, improves the accuracy of the hot water quantity display result, and thus improves the user experience.

[0070] Figure 2 Schematic diagram of the process of the method for displaying the amount of hot water in a water heater provided in an embodiment of the present application Figure 2 This embodiment is in Figure 1 Based on the embodiments, the method is described in detail. Figure 2 As shown, the method for displaying the amount of hot water in a water heater provided in this embodiment includes:

[0071] S201, determining the current water inlet temperature and mixed water temperature of the water heater.

[0072] Step S201 is similar to the above step S101 and will not be described again.

[0073] S202, determining a first difference between the mixed water temperature and the inlet water temperature, and a second difference between the product of the hot water volume corresponding to each hot water volume display segment, the inner tank volume of the water heater, and the hot water discharge rate of the water heater.

[0074] Among them, the first difference is used to reflect the difference between the water temperature actually used by the user and the cold water temperature. The second difference refers to the difference between the product of the hot water volume, the inner tank volume and the hot water discharge rate corresponding to each hot water volume display segment, which is used to reflect the change in the hot water supply capacity of the water heater under different usage conditions. The hot water discharge rate refers to the ratio of the actual amount of hot water that the water heater can output under rated conditions to its rated capacity.

[0075] S203: Divide the product of the first difference and the second difference by the volume of the water heater, and then add the mixed water temperature to obtain a temperature threshold corresponding to each hot water volume display level.

[0076] For example, the temperature threshold corresponding to each hot water volume display level can be calculated using the following formula:

[0077]

[0078] in, Display level for hot water volume The corresponding temperature threshold, is the mixing water temperature, is the inlet water temperature, Display level for hot water volume The corresponding amount of hot water, is the inner volume of the water heater, is the hot water discharge rate of the water heater.

[0079] It can be understood that the hot water level display level can be a value greater than or equal to 0. When the display level is 0, it means that the temperature in the tank is very low and the available hot water is very small. The larger the value of the display level is, the more hot water is available. In addition, the higher the display level is, the higher the corresponding temperature threshold is. For example, the temperature threshold corresponding to display level 0 is 36°C, the temperature threshold corresponding to display level 1 is 37°C, the temperature threshold corresponding to display level 2 is 45°C, the temperature threshold corresponding to display level 3 is 53°C, the temperature threshold corresponding to display level 4 is 61°C, and the temperature threshold corresponding to display level 5 is 71°C.

[0080] S204: When the inner tank temperature is greater than or equal to the temperature threshold corresponding to the first hot water volume display stage and less than the temperature threshold corresponding to the second hot water volume display stage, determine that the current hot water volume display stage is the first hot water volume display stage.

[0081] Among them, the first hot water volume display level and the second hot water volume display level refer to any display level among all display levels except the highest level hot water volume display level and the lowest level hot water volume display level, and the level of the second hot water volume display level is higher than the first hot water volume display level.

[0082] For example, when the actual inner tank temperature detected is greater than or equal to 37°C and less than 45°C, the current hot water volume display level is determined to be level 1; when the actual inner tank temperature is greater than or equal to 45°C and less than 53°C, the current hot water volume display level is determined to be level 2.

[0083] S205: When the temperature of the inner tank is greater than or equal to the temperature threshold corresponding to the highest level of hot water quantity display stage, determine that the current hot water quantity display stage is the highest level of hot water quantity display stage.

[0084] For example, if the highest level display level of the water heater is level 5, then when the actual temperature detected inside the tank is greater than or equal to 71°C, it is determined that the current hot water volume display level is level 5.

[0085] S206: When the temperature of the inner tank is lower than the temperature threshold corresponding to the lowest level of hot water quantity display stage, determine that the current hot water quantity display stage is the lowest level of hot water quantity display stage.

[0086] For example, if the highest level display level of the water heater is level 0, then when the actual inner tank temperature detected is less than 37°C, it is determined that the current hot water volume display level is level 0.

[0087] In some embodiments, when the water heater is a multi-tank water heater, the inner tank volume of the water heater includes the volume of each inner tank, and accordingly, the inner tank temperature of the water heater includes the temperature of each inner tank, the hot water volume corresponding to each hot water volume display segment includes the hot water volume corresponding to each hot water volume display segment of each inner tank, the hot water discharge rate of the water heater includes the hot water discharge rate of each inner tank, the temperature threshold corresponding to each hot water volume display segment includes the temperature threshold corresponding to each hot water volume display segment of each inner tank, and the current hot water volume display segment includes the current hot water volume display segment of each inner tank.

[0088] Among them, if the water heater is a multi-tank water heater, the temperature threshold corresponding to each hot water amount display level of each tank can be dynamically adjusted based on the mixed water temperature, the inlet water temperature, the volume of each tank, and the hot water discharge rate of each tank. The specific implementation process can be found in the relevant description corresponding to the above embodiment, which will not be repeated here.

[0089] Optionally, when the water heater is a double-tank water heater and the double tanks are arranged up and down, after determining the current hot water volume display level, if the current hot water volume display level of the lower tank is greater than the current hot water volume display level of the upper tank, the current hot water volume display level of the lower tank may be updated to the current hot water volume display level of the upper tank.

[0090] Among them, for a double-tank water heater with two tanks arranged upper and lower, when it operates in the double-tank mode, the display levels of the upper tank and the lower tank can be determined based on the temperature thresholds corresponding to their respective display levels, but when controlling the hot water level displayed in the lower tank, the display level of the lower tank is restricted to be less than or equal to the display level of the upper tank.

[0091] Optionally, when the difference between the current lower tank temperature and the set temperature is less than or equal to a preset threshold, it is determined that the current hot water volume display level of the lower tank is greater than or equal to the hot water volume display level corresponding to the lower tank temperature being the set temperature.

[0092] For example, when the difference between the current lower pot temperature and the set temperature is less than or equal to 2, it means that the lower pot temperature is close to the user's set temperature. At this time, the number of segments displayed on the lower pot needs to be limited to no less than the number of display segments corresponding to the set temperature. This restriction can only be lifted when the lower pot temperature is less than or equal to the insulation start temperature of the lower pot.

[0093] S207, displaying the current hot water volume display level.

[0094] Among them, in the case where the water heater is a double tank water heater and the double tanks are arranged up and down, if the double tank water heater operates in single tank mode, only the hot water volume display segment of the upper tank is displayed; if the double tank water heater operates in double tank mode, the hot water volume display segment of the upper tank and the hot water volume display segment of the lower tank are displayed at the same time. Optionally, the hot water volume display segment of the upper tank can be from right to left, with red displayed where there is water and blue displayed where there is no water; the hot water volume display segment of the lower tank can be from left to right. Here, when the lower tank is in the heating state, the indicator lights are lit from left to right to display the heating animation, and the indicator lights corresponding to a display segment are lit at intervals of 500ms, and enter the full-bright state in turn, and the other lights are half-bright.

[0095] The hot water quantity display method of the water heater provided in the present embodiment dynamically adjusts the temperature threshold corresponding to each hot water quantity display segment according to the mixed water temperature, the water inlet temperature, the hot water quantity corresponding to each hot water quantity display segment, the inner tank volume of the water heater and the hot water discharge rate, and determines the current hot water quantity display segment and controls its display according to the actual inner tank temperature and the current temperature thresholds of each hot water quantity display segment; in this way, the accuracy of the hot water quantity display segment is improved, the user is prevented from misjudging the hot water quantity due to inaccurate display, and the user experience is improved.
