[0018] Optionally, the step of controlling the air conditioner to execute the temperature energy-saving mode includes:

[0019] A detection cycle begins every first preset duration, until the preset temperature difference corresponding to the detection cycle increases to the maximum preset temperature difference; where

[0020] Within each detection cycle, the ambient temperature of the environment where the air conditioner is located is acquired every second preset time interval until the temperature difference between the ambient temperature and the set temperature is greater than or equal to the preset temperature difference corresponding to that cycle.

[0021] Within each detection cycle, when the temperature difference between the ambient temperature and the set temperature is less than the set temperature difference corresponding to that detection cycle, the current operating current value and the current energy saving percentage of the air conditioner are obtained.

[0031] Furthermore, if the air conditioner's operating time is less than the preset operating time, a preset current value is obtained. A second target current value is calculated from the preset current value and the energy saving percentage. The compressor frequency and indoor fan speed of the air conditioner are adjusted according to the second target current value, so that the indoor temperature can be reduced as quickly as possible and stabilized.

[0032] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0033] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0034] The following sections will describe some specific embodiments of the invention in detail by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0036] Figure 2 This is a schematic structural block diagram of an energy-saving control device for an air conditioner according to an embodiment of the present invention. Detailed Implementation

[0037] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0038] It should be noted that, without conflict, the technical features of the embodiments and optional embodiments of the present invention can be combined with each other.

[0039] Figure 1 This is a schematic flowchart of an energy-saving control method for an air conditioner according to an embodiment of the present invention. See also... Figure 1 As shown, the energy-saving control method for air conditioners proposed in this invention includes at least the following steps S102-S106.

[0040] Step S102: Receive energy-saving control instructions for the air conditioner;

[0041] Step S104: If the energy-saving control command instructs the air conditioner to execute the time-limited energy-saving mode, then control the air conditioner to execute the time-limited energy-saving mode.

[0042] Step S106: If the energy-saving control command instructs the air conditioner to execute the temperature energy-saving mode, then control the air conditioner to execute the temperature energy-saving mode.

[0043] Among them, the time-based energy-saving mode is mainly selected by the user. The time-based energy-saving mode incorporates a time parameter for judgment, and needs to take into account the user experience. Energy saving is only implemented when the user's basic needs are met.

[0044] Temperature-based energy-saving mode primarily relies on the air conditioner's temperature-achieving performance before actively saving energy.

[0045] In this embodiment of the invention, upon receiving an energy-saving control command for the air conditioner, if the command instructs the air conditioner to execute a duration-based energy-saving mode, then the air conditioner is controlled to execute that mode; if the command instructs the air conditioner to execute a temperature-based energy-saving mode, then the air conditioner is controlled to execute that mode. By controlling the air conditioner to execute different energy-saving modes, energy consumption can be reduced, thus saving energy and protecting the environment. Furthermore, providing both duration-based and temperature-based energy-saving modes for users to choose from improves the user experience of the air conditioner.

[0046] In one embodiment of the present invention, receiving an energy-saving control command about an air conditioner includes receiving an energy-saving control command input from a remote control of the air conditioner or an application program about the air conditioner.

[0047] Users can input energy-saving control commands via the air conditioner's remote control or the air conditioner's app.

[0048] In addition, in some embodiments of the present invention, the energy-saving control command may also be automatically triggered at a set time point.

[0049] In one embodiment of the present invention, the step S104 mentioned above, which involves controlling the air conditioner to perform a duration-based energy-saving mode, includes:

[0050] Obtain the percentage of energy savings from external input;

[0051] Get the operating time of the air conditioner;

[0052] If the working time of the air conditioner is greater than or equal to the preset working time, obtain multiple operating current values ​​of the air conditioner at different time points within the preset working time, determine multiple first current values ​​from the multiple operating current values, calculate the second current value from the multiple first current values, calculate the first target current value from the second current value and the energy saving percentage, and adjust the compressor frequency and indoor fan speed of the air conditioner with the first target current value.

[0053] The energy-saving percentage input from the outside can be entered by the user through the air conditioner's touch screen, buttons, or preset applications.

[0054] The energy-saving percentage can be selected in several levels, including 95%, 90%, and 85%, which are all below 1, and users can choose according to their needs.

[0055] The operating time of the air conditioner refers to the total operating time since it was turned on this time.

[0056] If the air conditioner's operating time is greater than or equal to the preset operating time, it indicates that the air conditioner is in a relatively stable operating state. At this time, the indoor ambient temperature is also in a relatively comfortable state. The operating current within the preset operating time of the air conditioner can reflect the user's usage habits. Therefore, at this time, multiple operating current values ​​of the air conditioner at different time points within the preset operating time are obtained.

[0057] The operating current value refers to the total operating current value of the air conditioner.

[0058] In one embodiment of the present invention, determining a plurality of first current values ​​from a plurality of current values ​​includes: determining the maximum current value and the minimum current value among a plurality of operating current values, and taking the remaining current value excluding the maximum current value and the minimum current value as the first current value.

[0059] The maximum and minimum current values ​​are quite extreme. By removing the maximum and minimum current values, the second current value calculated based on the remaining current value can more accurately reflect the user's usage habits of the air conditioner. Adjustments can be made accordingly to improve the user experience.

[0060] In one embodiment of the present invention, calculating a second current value from a plurality of first current values ​​includes: taking the average of the plurality of first current values ​​to obtain the second current value.

[0061] In one embodiment of the present invention, calculating the first target current value from the second current value and the energy saving percentage includes: multiplying the second current value and the energy saving percentage to obtain the first target current value.

[0062] Specifically, in adjusting the compressor frequency and indoor fan speed of the air conditioner with the first target current value, the current distribution ratio between the compressor and the indoor fan is first obtained, and then the first target current is distributed to the compressor and the indoor fan according to the current distribution ratio between the compressor and the indoor fan. The compressor frequency and the indoor fan speed are changed, thereby reducing the energy consumption of the air conditioner.

[0063] In this embodiment, after obtaining the energy-saving percentage and the working time of the air conditioner from the external input, if the working time of the air conditioner is greater than or equal to the preset working time, multiple operating current values ​​of the air conditioner at different time points within the preset working time are obtained, multiple first current values ​​are determined from the multiple operating current values, a second current value is calculated from the multiple first current values, a first target current value is calculated from the second current value and the energy-saving percentage, and the compressor frequency and indoor fan speed of the air conditioner are adjusted with the first target current value, thereby achieving the goal of the air conditioner meeting the user experience and saving energy.

[0064] In one embodiment of the present invention, after obtaining the working time of the air conditioner mentioned above, the method further includes: if the working time of the air conditioner is less than the preset working time, obtaining a preset current value, calculating a second target current value from the preset current value and the energy saving percentage, and adjusting the compressor frequency and the internal fan speed of the air conditioner with the second target current value.

[0065] If the air conditioner's operating time is less than the preset operating time, it indicates that the indoor ambient temperature is unstable and high, and the air conditioner's operating current value cannot reflect the user's usage habits.

[0066] The preset current value is a relatively large value. The second target current value is calculated by multiplying the preset current value by the energy saving percentage. Adjusting the compressor frequency and indoor fan speed of the air conditioner with the second target current value can make the indoor ambient temperature drop as quickly as possible to reach a stable state.

[0067] In this embodiment, if the working time of the air conditioner is less than the preset working time, a preset current value is obtained, and a second target current value is calculated from the preset current value and the energy saving percentage. The compressor frequency and indoor fan speed of the air conditioner are adjusted with the second target current value, so that the indoor temperature can be reduced as quickly as possible and stabilized.

[0068] In one embodiment of the present invention, the step S106 mentioned above, which involves controlling the air conditioner to execute a temperature-saving mode, includes:

[0069] A detection cycle begins every first preset duration, until the preset temperature difference corresponding to the detection cycle increases to the maximum preset temperature difference; where

[0070] Within each detection cycle, the ambient temperature of the environment where the air conditioner is located is acquired every second preset time interval until the temperature difference between the ambient temperature and the set temperature is greater than or equal to the preset temperature difference corresponding to that cycle.

[0071] Within each detection cycle, when the temperature difference between the ambient temperature and the set temperature is less than the set temperature difference corresponding to that detection cycle, the current operating current value and the current energy saving percentage of the air conditioner are obtained. The current target current value is calculated from the current operating current value and the current energy saving percentage. The compressor frequency and indoor fan speed of the air conditioner are adjusted according to the current target current value. The current energy saving percentage is lower than the previously determined energy saving percentage by a preset energy saving percentage. The preset temperature difference increases with the increase of the detection cycle.

[0072] The first preset duration can be selected as 30 minutes.

[0073] The preset temperature difference increases with the increase of the detection cycle. For example, the preset temperature difference corresponding to the first detection cycle can be 3℃, and the preset temperature difference corresponding to the subsequent detection cycles increases by 1℃ each time. The ambient temperature corresponding to the maximum preset temperature difference can be selected as 26℃. For example, if the set temperature is 20℃, then 6℃ is the maximum preset temperature difference.

[0074] The second preset duration can be set to 10 minutes.

[0075] It should be noted that the first preset duration and the second preset duration can be set according to the actual situation, and the present invention does not impose specific limitations.

[0076] In each detection cycle, if the temperature difference between the ambient temperature and the set temperature is less than the set temperature difference corresponding to that detection cycle, it indicates that the indoor temperature is in a state that makes the user feel relatively comfortable, and it is appropriate to adjust the air conditioner's current value to put the air conditioner into energy-saving mode.

[0077] The energy saving percentage for the first test cycle can be selected as 95%, while the preset energy saving percentage is 5%.

[0078] In one embodiment of the present invention, the current target current value is calculated from the current operating current value and the current energy saving percentage, including: multiplying the current operating current value and the current energy saving percentage to calculate the current target current value.

[0079] Specifically, when the preset temperature difference corresponding to the detection cycle increases to the maximum preset temperature difference, the air conditioner is controlled to operate in the set operating mode.

[0080] The operating mode can be preset by the user.

[0081] The following examples illustrate the use of temperature-saving modes in air conditioners to make the concept clearer.

[0082] The preset temperature difference for the first detection cycle is 3℃. When the temperature difference between the ambient temperature and the set temperature is less than 3℃, the current operating current value I0 and the current energy saving percentage of 95% of the air conditioner are obtained. The current target current value I1 = I0 * 95% is calculated, and the compressor frequency and fan speed are adjusted according to the current target current value I1.

[0083] After 10 minutes, i.e. the second preset time, if the temperature difference between the ambient temperature and the set temperature is still less than 3°C, continue to obtain the current operating current value I2 and the current energy saving percentage of 90% of the air conditioner, and calculate the current target current value I3 = I2 * 90%.

[0084] This process continues until the temperature difference between the ambient temperature and the set temperature is greater than or equal to 3°C, at which point the first detection cycle ends.

[0085] After the first testing cycle ends, the air conditioner will run for 30 minutes (the first preset time) at the current target current value determined in the last test cycle, and then enter the second testing cycle.

[0086] The preset temperature difference for the second testing cycle can be set to 4℃.

[0087] Optionally, the preset temperature difference increases by +1℃ as the cycle increases.

[0088] The calculation and control process for energy saving of the air conditioner in subsequent testing cycles is the same as in the first testing cycle. The cycle continues until the preset temperature difference reaches the maximum preset temperature difference, at which point the air conditioner will operate in the set operating mode.

[0089] In this embodiment, when controlling the air conditioner to execute the temperature-saving mode, a detection cycle begins every first preset duration until the preset temperature difference corresponding to the detection cycle increases to the maximum preset temperature difference. Within each detection cycle, the ambient temperature of the air conditioner's environment is acquired every second preset duration until the temperature difference between the ambient temperature and the set temperature is greater than or equal to the preset temperature difference corresponding to that cycle. Within each detection cycle, when the detected temperature difference between the ambient temperature and the set temperature is less than the set temperature difference corresponding to that detection cycle, the current operating current value and the current energy-saving percentage of the air conditioner are acquired. The current target current value is calculated from the current operating current value and the current energy-saving percentage, and the compressor frequency and indoor fan speed of the air conditioner are adjusted based on the current target current value. The current energy-saving percentage is a preset energy-saving percentage lower than the previously determined energy-saving percentage, and the preset temperature difference increases with the increase of the detection cycle. This mode ensures that the air conditioner's energy saving is met while also satisfying the user experience.

[0090] Based on the same inventive concept, this invention also proposes an energy-saving control device 20 for an air conditioner. Figure 2 This is a schematic structural block diagram of an energy-saving control device for an air conditioner according to an embodiment of the present invention. See also... Figure 2 As shown, the energy-saving control device 20 includes a processor 210 and a memory 220. The memory 220 stores a computer program 221; when the computer program 221 is run by the processor 210, it causes the control device 20 to perform the method of any of the above embodiments.

[0091] The energy-saving control device 20 can be connected to the air conditioner's data and can be deployed on network-side devices such as servers or cloud computing platforms. The energy-saving control device 20 can also be a centralized control device, deployed in or around the environment where the air conditioner is located. Data connection methods between the energy-saving control device 20 and the air conditioner include, but are not limited to, wireless transmission, infrared transmission, and ultrasonic transmission. The energy-saving control device 20 can also be integrated into the air conditioner and installed inside it.

[0092] This invention provides an energy-saving control method and device for an air conditioner. Upon receiving an energy-saving control command for the air conditioner, if the command instructs the air conditioner to execute a duration-based energy-saving mode, then the air conditioner is controlled to execute that mode; if the command instructs the air conditioner to execute a temperature-based energy-saving mode, then the air conditioner is controlled to execute that mode. By controlling the air conditioner to execute different energy-saving modes, energy consumption can be reduced, thus achieving energy conservation and environmental protection.

[0093] Furthermore, the present invention provides users with a time-based energy-saving mode and a temperature-based energy-saving mode to choose from, thereby improving the user experience of the air conditioner.

[0094] Furthermore, after obtaining the energy-saving percentage and the air conditioner's operating time from external input, if the air conditioner's operating time is greater than or equal to the preset operating time, multiple operating current values ​​of the air conditioner at different time points within the preset operating time are obtained. Multiple first current values ​​are determined from the multiple operating current values, and a second current value is calculated from the multiple first current values. A first target current value is calculated from the second current value and the energy-saving percentage. The compressor frequency and indoor fan speed of the air conditioner are adjusted with the first target current value, thereby achieving the goal of the air conditioner meeting user experience requirements while saving energy.

[0095] Furthermore, if the air conditioner's operating time is less than the preset operating time, a preset current value is obtained. A second target current value is calculated from the preset current value and the energy saving percentage. The compressor frequency and indoor fan speed of the air conditioner are adjusted according to the second target current value, so that the indoor temperature can be reduced as quickly as possible and stabilized.

[0096] Furthermore, when controlling the air conditioner to execute the temperature-saving mode, a detection cycle begins every first preset duration until the preset temperature difference corresponding to the detection cycle increases to the maximum preset temperature difference. Within each detection cycle, the ambient temperature of the air conditioner's environment is acquired every second preset duration until the temperature difference between the ambient temperature and the set temperature is greater than or equal to the preset temperature difference corresponding to that cycle. Within each detection cycle, when the detected temperature difference between the ambient temperature and the set temperature is less than the set temperature difference corresponding to that detection cycle, the current operating current value and the current energy-saving percentage of the air conditioner are acquired. The current target current value is calculated from the current operating current value and the current energy-saving percentage, and the compressor frequency and indoor fan speed of the air conditioner are adjusted based on the current target current value. The current energy-saving percentage is a preset energy-saving percentage lower than the previously determined energy-saving percentage, and the preset temperature difference increases with the increase of the detection cycle. This mode ensures that the air conditioner's energy efficiency is maintained while also satisfying the user experience.

[0097] Furthermore, the functional units in the various embodiments of the present invention can be physically independent of each other, or two or more functional units can be integrated together, or all functional units can be integrated into one processing unit. The integrated functional units described above can be implemented in hardware, or in software or firmware.

Based on this understanding, the technical solution of the present invention, or all or part of it, can be embodied in the form of a software product.
