Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of household appliances, and in particular to a temperature control method and device for a water heater, a water heater, and a storage medium. Background Art

[0002] Water heaters are everyday household appliances. Users can adjust the water temperature to their desired temperature, ensuring a comfortable bathing experience. Solar water heaters often feature an electric auxiliary heating function. When the user determines the water tank temperature is low, they can operate the electric heating device to heat the water to a desired temperature.

[0003] In the prior art, when the current temperature of a water heater is lower than the target temperature, the heater's electric heating device activates heating to bring the water temperature to the target. However, if the current temperature is equal to or greater than the target temperature, heating is not activated, rendering the current operation ineffective. The target temperature must be adjusted to a value higher than the current temperature before heating can be activated again. The user experience of these prior art water heaters is poor, requiring the user to make repeated judgments and perform repeated operations under these specific conditions. Summary of the Invention

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0028] Example 1

[0029] Figure 1 This is a flow chart of a water heater temperature control method provided in Example 1 of the present invention. This embodiment is applicable to temperature regulation in a solar water heater. The method can be performed by a water heater temperature control device in an embodiment of the present invention, wherein the device can be implemented by software and / or hardware. The device can be integrated into a device that can provide temperature control functions, typically integrated into a water heater controller. The method specifically includes the following steps:

[0030] Step S110: Obtain the user's temperature adjustment instruction.

[0031] The water heater receives the temperature control command sent by the user and controls the heater's heating according to the temperature adjustment command set by the user. When the water temperature in the water heater does not meet the user's requirements, the user sends a temperature adjustment command to the water heater according to their needs. Users can send temperature control commands to the water heater in various ways, such as through mobile devices such as smartphones, smart bracelets, and tablets, or directly through the temperature control command buttons or touch controls provided on the water heater device.

[0032] The panel sends instructions

[0033] In the embodiment of the present invention, it is typically applied to a solar water heater. A solar water heater mainly relies on solar energy to heat water, but when a user needs a large amount of hot water or when solar radiation is insufficient, an auxiliary electric heater can be activated to heat the water.

[0034] Step S120: Identify the relationship between the command temperature corresponding to the temperature adjustment command and the target upper limit temperature of the water heater.

[0035] The water heater's target upper limit temperature is typically the default or last used setting, i.e., the default user-customized temperature or the historical data of user-set temperatures. This is different from a user-set temperature adjustment command. The water heater must identify the command temperature corresponding to the user-set temperature adjustment command and the water heater's target upper limit temperature. This identification process involves determining the difference between the command temperature and the target upper limit temperature. There are cases where the command temperature is greater than, equal to, or less than the target upper limit temperature.

[0036] Step S130: If the command temperature is greater than the target upper limit temperature, adjust the target upper limit temperature to be greater than or equal to the command temperature.

[0037] Among them, when the instruction temperature is greater than the target upper limit temperature, the water heater adjusts the target upper limit temperature to be greater than or equal to the instruction temperature. During the use of the water heater, if the water temperature is not high due to weather or other reasons, the user will usually manually start the electric heating and send a temperature adjustment instruction to the water heater. The target upper limit temperature value of the water heater is generally the default or the last set value. If the target upper limit temperature of this operation is lower than the instruction temperature sent by the user, the water heater will adjust the target upper limit temperature to be greater than or equal to the instruction temperature. For example, the current target upper limit temperature of the water heater is 50 degrees Celsius, and the instruction temperature set by the user according to his own needs is 55 degrees Celsius. At this time, the target upper limit temperature is lower than the instruction temperature set by the user. The water heater can adjust the target upper limit temperature to 65 degrees Celsius or 55 degrees Celsius. At this time, the target upper limit temperature is greater than or equal to the instruction temperature.

[0038] Step S140: According to the temperature adjustment instruction, the heater of the water heater is controlled to operate until the water temperature reaches the instruction temperature.

[0039] The acquired temperature control command is then used to control the heating of the water heater. The water heater's electric heating device is an energy conversion device that converts the acquired temperature control command into heat energy at a specific temperature, thereby heating the water in the water heater until it reaches the user's desired set temperature. For example, if the acquired temperature control command is 55 degrees Celsius and the water temperature in the water heater is 40 degrees Celsius, the heater in the water heater will heat the water to the commanded temperature of 55 degrees Celsius upon receiving the command before stopping. If the temperature command exceeds the target upper limit temperature, the electric heating device in the water heater will stop heating after reaching the target upper limit temperature. Therefore, the water heater adjusts the target upper limit temperature. For example, if the current target upper limit temperature of the water heater is 50 degrees Celsius and the user sets the commanded temperature to 55 degrees Celsius, the target upper limit temperature is lower than the user-set commanded temperature. Because the water heater reaches the target upper limit temperature, it will not continue to heat up and will not reach the user's set temperature. Therefore, the target upper limit temperature of the water heater can be automatically adjusted. The target upper limit temperature can be set to a temperature higher than the command temperature set by the user, such as 65 degrees Celsius. At this time, the electric heating device of the water heater heats to a target upper limit temperature higher than the command temperature to meet the user's temperature requirements.

[0040] This embodiment provides a water heater temperature control method, which first obtains a user's temperature adjustment instruction; then identifies the relationship between the command temperature corresponding to the temperature adjustment instruction and the target upper limit temperature of the water heater; if the command temperature is greater than the target upper limit temperature, adjusts the target upper limit temperature to be greater than or equal to the command temperature; and finally, controls the operation of the water heater according to the temperature adjustment instruction until the water temperature reaches the command temperature. By adjusting the target upper limit temperature to be greater than or equal to the command temperature, the water heater temperature control method solves the problem of repeated operations in which the water heater stops heating after reaching the target upper limit temperature due to the command temperature being higher than the target upper limit temperature, and needs to adjust the target temperature before it can be restarted to reach the command temperature. The method achieves the effect of automatically determining the difference between the current temperature and the target temperature and adjusting it, avoiding repeated operations caused by displaying a high command temperature.

[0041] Example 2

[0042] Figure 2A This is a flow chart of a water heater temperature control method provided by the second embodiment of the present invention. This second embodiment is a refinement of the above embodiment. In this embodiment, the method specifically includes the following steps:

[0043] S210: Obtain a command temperature generated by a user through touch input, voice input, or button input, and generate the temperature adjustment command according to the command temperature.

[0044] The water heater device itself can receive temperature adjustment commands sent by the user in various ways. The user can generate a command temperature by inputting through conventional buttons on the water heater; the water heater can have a touchscreen panel, on which the user can generate a command temperature by touch input; or the water heater can have a voice recognition function that can recognize the user's voice, receive the user's voice input, generate a command temperature, and control the water heater based on the generated command temperature. The user can generate temperature adjustment commands in various ways, making operation convenient and providing a good user experience.

[0045] S220. Determine whether the target upper limit temperature is greater than or equal to the sum of the command temperature and a preset increase range. If so, maintain the target upper limit temperature unchanged; if not, set the target upper limit temperature equal to the sum of the command temperature and the preset increase range.

[0046] The preset temperature increase refers to the temperature increase range set by the water heater based on the command temperature. The water heater compares the sum of the command temperature and the preset temperature increase with the target upper limit temperature. For example, if the target upper limit temperature of 65 degrees Celsius is greater than the sum of the command temperature of 50 degrees Celsius and the preset temperature increase of 10 degrees Celsius, or if the target upper limit temperature of 65 degrees Celsius is equal to the sum of the command temperature of 55 degrees Celsius and the preset temperature increase of 10 degrees Celsius, the target upper limit temperature of 65 degrees Celsius is maintained unchanged and no adjustment is required. If the target upper limit temperature of 60 degrees Celsius is not greater than or equal to the sum of the command temperature of 55 degrees Celsius and the preset temperature increase of 10 degrees Celsius, the target upper limit temperature of 65 degrees Celsius is set to be equal to the sum of the command temperature of 55 degrees Celsius and the preset temperature increase of 10 degrees Celsius. By adding the preset temperature increase, the command temperature can create a certain temperature difference with the target upper limit temperature, so that the command temperature does not easily reach the target upper limit temperature, making the operation of adjusting the target upper limit temperature of the water heater more substantial.

[0047] Optionally, adjusting the target upper limit temperature to be greater than or equal to the command temperature further includes:

[0048] A preset increase range is determined according to at least one water temperature control factor; and the target upper limit temperature is adjusted to be greater than or equal to the command temperature according to the preset increase range.

[0049] The water temperature control factor is an adjustment factor for the preset temperature increase, adjusting the preset temperature increase based on different circumstances. The preset temperature increase is not a fixed value and can be adaptively adjusted based on the water temperature control factor to better meet user needs and optimize the user experience. The water heater adjusts the target upper limit temperature by adding the preset temperature increase determined by the water temperature control factor to the command temperature, ensuring that the target upper limit temperature is greater than or equal to the command temperature.

[0050] Optionally, the water temperature control factor includes at least one of the following:

[0051] If the water temperature control factor is a seasonal factor, the preset increase in winter is greater than the preset increase in summer; if the water temperature control factor is a weather factor, the preset increase is inversely proportional to the intensity of solar radiation; if the water temperature control factor is a capacity factor, the preset increase is inversely proportional to the capacity of the water heater; if the water temperature control factor is a user behavior factor, the preset increase is determined based on the user's historical behavior in setting the target upper limit temperature.

[0052] The water temperature adjustment factor can adjust the preset temperature increase based on different circumstances, such as seasonal factors, weather factors, water capacity factors, and user behavior. When the water temperature adjustment factor is seasonal, the temperature difference between winter and summer is significant. Winter temperatures are lower, so users have higher water temperature requirements, while summer temperatures are higher, so users do not need to be as demanding. Therefore, the water temperature adjustment factor can be used to adjust the preset temperature increase in winter to a greater value than in summer. For example, the preset temperature increase in winter is 10 degrees Celsius, while the preset temperature increase in summer is 5 degrees Celsius. When the water temperature control factor is weather, it is related to the intensity of solar radiation received by the water heater on that day. When the intensity of solar radiation is high, the water temperature in the water heater is higher, so the preset temperature increase can be adaptively reduced; otherwise, it increases, so the preset temperature increase is inversely proportional to the solar radiation intensity. Similarly, the water temperature control factor can be used to adjust the preset temperature increase based on the capacity of the water heater. A larger capacity requires a larger amount of water to be heated, so the preset temperature increase is larger; otherwise, it is reduced. The water temperature control factor can determine the preset increase range according to the user's behavior factor, and the preset increase range can be adjusted according to the user's historical data and the user's setting habits.

[0053] S230: After adjusting the target upper limit temperature to be greater than or equal to the command temperature, a temperature setting range greater than the command temperature is set based on the command temperature, and the temperature setting range is updated to the target upper limit temperature setting range.

[0054] The lower limit of the temperature setting range is the command temperature plus a preset interval, and the upper limit of the temperature setting range is the maximum safe temperature.

[0055] Among them, the preset interval is used to determine the lower limit of the temperature range. It is a reserve amount added to the instruction temperature benchmark, and the lower limit of the temperature is slightly higher than the instruction temperature. It can alleviate the user experience affected by the heat loss caused by the hot water of the water heater during the transmission process when the water demand is high. The maximum safe temperature refers to the highest temperature that the human body can accept, preventing harm to the user's body due to unlimited heating of the water heater. When the water heater adjusts the target upper limit temperature, the range of the target upper limit temperature is re-determined. Based on the instruction temperature set by the user, the range greater than the instruction temperature to the set target upper limit temperature is updated to the new target upper limit temperature setting range. The temperature setting range also has upper and lower limits. The updated lower limit temperature is the instruction temperature plus the preset interval, which can meet the target temperature greater than or equal to the instruction temperature. At the same time, the upper limit value of the temperature range cannot exceed the maximum safe temperature. The upper limit value of the range is determined as the maximum safe temperature value to ensure user safety.

[0056] S240: According to the temperature adjustment instruction, control the heater of the water heater to operate until the water temperature reaches the instruction temperature.

[0057] Optionally, when a set cooling condition is met, the target upper limit temperature is restored to the previous target upper limit temperature value; wherein the set cooling condition includes: no heating demand within a set time period.

[0058] The cooling condition refers to when the water heater's electric heating device no longer needs to provide heat, such as when the user's demand for hot water ends or the water heater no longer needs to provide heating for a set period of time. The water heater will restore the target upper limit temperature to the previous target upper limit value to meet the user's previous usage habits.

[0059] Figure 2B This is a flowchart of an example of a water heater temperature control method provided in the second embodiment of the present invention. In this specific example, when the user sends a temperature adjustment instruction, the water heater first identifies the target upper limit value. If the current target upper limit value T2 is 10 degrees Celsius or higher than the instruction temperature T1 sent by the user, and the 10 degrees Celsius is the preset increase, then T2 is the last set target upper limit value; if the last set target upper limit value T2 is no more than 1 degree Celsius higher than the instruction temperature T1 sent by the user, then T2 is re-determined to be the value of (instruction temperature T1 + 10 degrees Celsius). At the same time, the temperature setting range is adjusted to (instruction temperature T1 + 2 degrees Celsius) to 75 degrees Celsius, where 2 degrees Celsius is the preset interval and 75 degrees Celsius is the maximum safe temperature. It is convenient for users to choose independently.

[0060] The water heater temperature control method provided in the second embodiment of the present invention addresses the issue of the water heater failing to reach the commanded temperature due to the user's commanded temperature being higher than the target upper limit temperature by specifying how to obtain the user's temperature adjustment command, as well as the target upper limit temperature adjustment process and temperature range. The water heater automatically determines the difference between the current temperature and the target temperature and adjusts accordingly. Regardless of the temperature relationship between the commanded temperature and the target upper limit temperature, the water heater can be heated to the commanded temperature, providing the user with the desired hot water.

When the water heater automatically determines the difference between the current temperature and the target temperature and makes adjustments, it can heat the water to the instruction temperature regardless of the temperature relationship between the instruction temperature and the target upper limit temperature, providing the user with the desired hot water effect.

[0069] Optionally, the instruction acquisition module 310 specifically includes:

[0076] The water temperature control factor is the capacity factor, and the preset increase is inversely proportional to the capacity of the water heater;

[0077] The water temperature control factor is a user behavior factor, and the preset increase range is determined based on the user's historical behavior in setting the target upper limit temperature;

[0080] The recovery unit is used to restore the target upper limit temperature to the previous target upper limit temperature value when the set cooling condition is met; wherein the set cooling condition includes: no heating demand within a set time period.
