Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to an air conditioner and its energy-saving control method. Background Technology

[0002] Intelligent voice technology is one of the most mature applications of artificial intelligence, possessing natural interactivity, meaning that intelligent devices can understand human speech. With the increasing prevalence of intelligent voice technology in air conditioners, the current trend is towards air conditioning products that utilize voice functionality through a combination of MCU (Microcontroller Unit) and voice modules. In this approach, the voice module acts as a separate system within the air conditioner, recognizing external voice signals, resulting in simple user operation and convenient control.

[0003] Currently, voice-controlled air conditioners are controlled via remote control or voice commands, but they cannot provide precise control based on the user's usage scenario. They cannot accurately locate and identify users in sleep or unoccupied scenarios, leading to wasted air conditioner resources and a poor user experience. Furthermore, when the air conditioner's light sensor detects that the ambient light is below a certain level, the air conditioner automatically turns off the backlight. Some users mistakenly believe that the air conditioner has been turned off because they see the backlight off, resulting in unnecessary power consumption and financial loss for the user. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, one objective of this invention is to provide an air conditioner that enables precise control of the air conditioner in a sleep scenario, avoiding power consumption caused by the air conditioner entering sleep mode and the backlight turning off, without increasing hardware costs, thus improving the user experience.

[0006] Therefore, the second objective of this invention is to provide an energy-saving control method for air conditioners.

[0007] To achieve the above objectives, a first aspect of the present invention provides an air conditioner, comprising: an outdoor unit having a compressor; an indoor unit connected to the outdoor unit; a light sensor disposed in the indoor unit for detecting the light intensity of the indoor environment; a sound sensor disposed in the indoor unit for detecting the sound intensity of the indoor environment; and a controller configured to receive a voice control command or receive the light intensity and the sound intensity; control the air conditioner to operate in a sleep state or control the air conditioner to operate in a non-sleep state according to the received voice control command or the light intensity and the sound intensity; and acquire a first operating time stage, a first light intensity, a first sound intensity, and a first operating duration of the air conditioner in the sleep state, and according to... The compressor is controlled to operate at a first preset frequency, or at a second preset frequency, or to stop, based on at least one of the first operating time stage, the first light intensity, the first sound intensity, and the first operating duration; and the second operating time stage, the second light intensity, the second sound intensity, and the second operating duration of the air conditioner in the non-sleep state are acquired, and the compressor is controlled to operate at the first preset frequency, or at the second preset frequency, or to stop, based on at least one of the second operating time stage, the second light intensity, the second sound intensity, and the second operating duration, wherein the first preset frequency is less than the second preset frequency.

[0008] According to an embodiment of the present invention, the air conditioner detects light and sound intensity using a combination of light and sound sensors. Based on the light and sound intensity or voice control commands, the air conditioner is controlled to operate in a corresponding state. During operation in the corresponding state, the operating stage and duration of the air conditioner are obtained. Combined with the light and sound intensity of the indoor environment, the compressor is controlled to operate at different preset frequencies or to stop. This enables more precise control of the air conditioner for sleep scenarios. By adjusting the compressor frequency or stopping the compressor in the corresponding scenario, unnecessary power consumption caused by forgetting to turn off the air conditioner when it enters sleep mode and the backlight is off can be avoided, thus saving power consumption without increasing hardware costs and improving the user experience.

[0009] In some embodiments, when the compressor is controlled to operate at the first preset frequency, or controlled to operate at the second preset frequency, or controlled to stop, based on at least one of the first operating time stage, the first light intensity, the first sound intensity, and the first operating duration, the controller is configured to: control the compressor to operate at the first preset frequency when the first operating time stage is in the first preset operating time stage; and control the compressor to stop when the first operating time stage is in the first preset operating time stage, and the first light intensity is less than the preset light intensity, and the first sound intensity is less than the preset sound intensity, and the first operating duration is within the first preset duration range.

[0010] In some embodiments, after controlling the compressor to stop, the controller is further configured to: if the first light intensity is detected again to be greater than the preset light intensity, control the compressor to restart.

[0011] In some embodiments, when the compressor is controlled to operate at the first preset frequency, or controlled to operate at the second preset frequency, or controlled to stop, based on at least one of the second operating time stage, the second light intensity, the second sound intensity, and the second operating duration, the controller is configured to: control the compressor to operate at the second preset frequency when the second operating time stage is within the first preset operating time stage and the second light intensity is greater than the preset light intensity; or control the compressor to operate at the first preset frequency when the second operating time stage is within the first preset operating time stage, the second light intensity is less than the preset light intensity, the second sound intensity is less than the preset sound intensity, and the second operating duration is within the second preset duration range; or control the compressor to stop when the second operating time stage is within the first preset operating time stage, the second light intensity is less than the preset light intensity, the second sound intensity is less than the preset sound intensity, and the first operating duration is within the first preset duration range.

[0013] In some embodiments, after controlling the compressor to stop, the controller is further configured to: upon receiving a control command to control the air conditioner to start again, control the air conditioner to start again.

[0014] In some embodiments, when the compressor is controlled to run at a first preset frequency, the controller is configured to: determine whether the air conditioner is in heating mode; if so, control the air conditioner to run at a third preset frequency; otherwise, control the air conditioner to run at a fourth preset frequency.

[0015] In some embodiments, after the compressor is restarted, the controller is configured to control the compressor to operate at the second preset frequency.

[0016] In some embodiments, when the air conditioner is controlled to operate in sleep mode or non-sleep mode based on the received light request and the sound intensity, the controller is configured to: control the air conditioner to operate in sleep mode when the light intensity is less than the preset light intensity and the sound intensity is less than the preset sound intensity; and control the air conditioner to operate in non-sleep mode when the light intensity is greater than the preset light intensity and the sound intensity is greater than the preset sound intensity.

[0017] To achieve the above objectives, a second aspect of the present invention provides an energy-saving control method for an air conditioner, the method comprising: receiving a voice control command or receiving light intensity and sound intensity; controlling the air conditioner to operate in a sleep state or to operate in a non-sleep state according to the received voice control command or the light intensity and sound intensity; acquiring a first operating time stage, a first light intensity, a first sound intensity, and a first operating duration of the air conditioner in the sleep state, and controlling the compressor to operate at a first preset frequency, or at a second preset frequency, or controlling the compressor to stop, according to at least one of the first operating time stage, the first light intensity, the first sound intensity, and the first operating duration; and acquiring a second operating time stage, a second light intensity, a second sound intensity, and a second operating duration of the air conditioner in the non-sleep state, and controlling the compressor to operate at the first preset frequency, or at a second preset frequency, or controlling the compressor to stop, wherein the first preset frequency is less than the second preset frequency.

[0018] According to the energy-saving control method of the air conditioner according to the embodiments of the present invention, the air conditioner is controlled to operate in a corresponding state based on the joint detection of light intensity and sound intensity by light sensor and sound sensor, or voice control command, and the operating stage and operating time of the air conditioner are obtained when the air conditioner is running in the corresponding state. Combined with the light intensity and sound intensity of the indoor environment, the compressor is controlled to run at different preset frequencies or the compressor is controlled to stop. This achieves more precise control of the air conditioner for sleep scenarios. By adjusting the compressor frequency or controlling the compressor to stop in the corresponding scenario, unnecessary power consumption caused by forgetting to turn off the air conditioner when it enters sleep mode and the air conditioner backlight is off can be avoided, thereby saving power consumption without increasing hardware costs and improving user experience.

[0031] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0032] In this invention, the air conditioner performs a refrigeration cycle using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to the conditioned and heat-exchanged air.

[0033] The compressor compresses refrigerant gas under high temperature and pressure and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0034] The expansion valve expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-temperature, low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0035] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0036] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0037] The following is for reference. Figures 1-8 Air conditioner 1, according to an embodiment of the present invention.

[0038] like Figure 1 As shown, the air conditioner 1 of this embodiment includes: an outdoor unit 11, an indoor unit 12, a light sensor 13, a sound sensor 14, and a controller 15, wherein...

[0039] The outdoor unit 11 has a compressor; the indoor unit 12 is connected to the outdoor unit 11; a sound sensor 14 is installed in the indoor unit 12 to detect the light intensity of the indoor environment; a sound sensor 14 is installed in the indoor unit 12 to detect the sound intensity of the indoor environment; the controller 15 is configured to receive voice control commands or receive light intensity and sound intensity; control the air conditioner 1 to operate in sleep mode or control the air conditioner 1 to operate in non-sleep mode according to the received voice control commands or light intensity and sound intensity; acquire the first operating time stage, first light intensity, first sound intensity and first operating duration of the air conditioner 1 in sleep mode, and according to the first operating... The system controls the compressor to operate at a first preset frequency, or to operate at a second preset frequency, or to stop the compressor, based on at least one of the following: time phase, first light intensity, first sound intensity, and first operating duration; and obtains the second operating time phase, second light intensity, second sound intensity, and second operating duration of the air conditioner 1 in a non-sleep state, and controls the compressor to operate at the first preset frequency, or to operate at the second preset frequency, or to stop the compressor, based on at least one of the following: second operating time phase, second light intensity, second sound intensity, and second operating duration, wherein the first preset frequency is less than the second preset frequency.

[0040] In this embodiment, when the air conditioner 1 is powered on, the light sensor 13 detects the light intensity of the indoor environment in real time and sends the light intensity to the controller 15, and the sound sensor 14 detects the sound intensity of the indoor environment in real time and sends the sound intensity to the controller 15; at the same time, the controller 15 queries the current time in the cloud.

[0041] The controller 15 controls the air conditioner 1 to enter different operating states according to the above parameters. For example, depending on the light intensity and sound intensity, the controller 15 controls the air conditioner 1 to operate in sleep mode or in non-sleep mode. Alternatively, the controller 15 can also receive voice control commands from the user and control the air conditioner 1 to operate in sleep mode or in non-sleep mode according to the voice control commands.

[0042] When the air conditioner 1 is running in sleep mode, the controller 15 acquires at least one of the following: a first running time stage, a first light intensity, a first sound intensity, and a first running duration. For example, the first running time stage is acquired based on the time in the cloud; the first light intensity is acquired based on the light intensity of the current indoor environment detected by the light sensor 13; the first sound intensity is acquired based on the sound intensity of the current indoor environment detected by the sound sensor 14; the time when the air conditioner 1 enters sleep mode is recorded to acquire the first running duration; and after acquiring the above parameters, the controller controls the compressor to run at a first preset frequency, or controls the compressor to run at a second preset frequency, or controls the compressor to stop, based on one or more of the above parameters, so as to reduce the operating frequency of the compressor or control the compressor to stop when the backlight is off in sleep mode, thereby saving energy.

[0043] When the air conditioner 1 is running in non-sleep mode, the controller 15 acquires at least one of the following: a second operating time stage, a second light intensity, a second sound intensity, and a second operating duration. For example, it acquires the second operating time stage based on the time in the cloud; it acquires the second light intensity based on the light intensity detected by the light sensor 13; it acquires the second sound intensity based on the sound intensity detected by the sound sensor 14; it records the time when the air conditioner 1 enters non-sleep mode to acquire the second operating duration; and after acquiring the above parameters, it controls the compressor to run at a first preset frequency, or controls the compressor to run at a second preset frequency, or controls the compressor to stop, based on one or more of the above parameters. By detecting the light intensity and sound intensity of the indoor environment and combining them with the operating stage and operating duration of the air conditioner 1, the controller controls the air conditioner 1 to enter the corresponding operating state and controls the compressor to change its frequency or stop the compressor accordingly in different operating states, thereby achieving precise control of the indoor space by the air conditioner 1 and improving the user experience.

[0044] According to an embodiment of the present invention, the air conditioner 1 detects light intensity and sound intensity jointly by a light sensor 13 and a sound sensor 14, and controls the air conditioner 1 to operate in a corresponding state based on the light intensity, sound intensity, or voice control commands. When operating in the corresponding state, the air conditioner 1 obtains the operating stage and operating time, and combines the light intensity and sound intensity of the indoor environment to control the compressor to operate at different preset frequencies or control the compressor to stop, so as to achieve more precise control of the air conditioner 1 for sleep scenarios. By adjusting the compressor frequency or controlling the compressor to stop in the corresponding scenario, the unnecessary power consumption caused by forgetting to turn off the air conditioner when the air conditioner 1 enters sleep mode and the air conditioner backlight is off can be avoided, thereby saving power consumption without increasing hardware costs and improving user experience.

[0045] In some embodiments, when the compressor is controlled to operate at a first preset frequency, or controlled to operate at a second preset frequency, or controlled to stop, based on at least one of the first operating time stage, the first light intensity, the first sound intensity, and the first operating duration, the controller 15 is configured to: control the compressor to operate at the first preset frequency when the first operating time stage is within the first preset operating time stage; and control the compressor to stop when the first operating time stage is within the first preset operating time stage, and the first light intensity is less than the preset light intensity, and the first sound intensity is less than the preset sound intensity, and the first operating duration is within the first preset duration range.

[0046] In this embodiment, the controller 15 synchronously queries the cloud for the current time and divides the 24 hours into a first preset running time period and a second preset running time period. The first preset running time period is, for example, the Y1 time period [8:00-18:00], and the second preset running time period is, for example, the Y2 time period [18:00-8:00]. The preset light intensity is the light intensity under normal visible light conditions, such as artificial light or sunlight, and is denoted as α. 标 The preset sound intensity is the indoor quiet speech signal intensity, typically 40 dBm, for example, denoted as δ. 标 The initial running time of air conditioner 1 is denoted as T0, the real-time running time of air conditioner 1 in sleep stage 1 is denoted as T1, the real-time running time of air conditioner 1 in sleep stage 2 is denoted as T2, and the first preset duration range is the difference between the real-time running time T2 of air conditioner 1 in sleep stage 2 and the initial running time T0 of air conditioner 1, for example, denoted as T2-T0.

[0047] like Figure 2As shown, when the air conditioner 1 is running in sleep mode, the first light intensity detected by the light sensor 13 is denoted as α1, the first sound intensity detected by the sound sensor 14 is denoted as δ1, and the controller 15 times the first running time of the air conditioner 1 in sleep mode is denoted as ΔT2. The controller 15 determines whether the first running time period is within the first preset running time period of 8:00-18:00. If the first running time period is within the first preset running time period of 8:00-18:00, the controller controls the compressor to run at the first preset frequency. By reducing the operating frequency of the compressor in sleep mode, the noise impact on the user's sleep state is reduced.

[0048] When the first operating time phase of air conditioner 1 falls within the first preset operating time phase of 8:00-18:00, the first light intensity α1 is compared with the preset light intensity α. 标 The relationship between the first sound intensity δ1 and the preset sound intensity δ 标 The relationship between the first running time ΔT2 and whether it is within the first preset time range T2-T0, if the first light intensity α1 is less than the preset light intensity α 标 That is, α1 < α 标 And the first sound intensity δ1 is less than the preset sound intensity δ 标 That is, δ1 < δ 标 If the first running time △T2 is within the first preset time range T2-T0, i.e. △T2<T2-T0, it is assumed that the air conditioner 1 is running in sleep mode and the backlight of the air conditioner 1 is off. If the user forgets to turn off the air conditioner 1, resulting in power waste, the compressor is controlled to stop to avoid power loss caused by the user forgetting to turn off the air conditioner 1, so as to achieve precise control of the sleep scenario.

[0049] In some embodiments, after the compressor is stopped, the controller 15 is further configured to: if the first light intensity is detected to be greater than the preset light intensity again, control the compressor to restart.

[0050] In this embodiment, after the air conditioner 1 is running in sleep mode and the controller 15 controls the compressor to stop, if the first light intensity α1 detected by the light sensor 13 is greater than the preset light intensity α, 标 That is, α1 > α 标 If the compressor restarts, it wakes up air conditioner 1. After waking up, the compressor's operating frequency returns to the frequency it was at before entering the sleep mode, and the backlight brightness of air conditioner 1 turns on simultaneously. After the compressor stops, the intensity of the first light source continues to be detected to achieve intelligent control of the compressor of air conditioner 1 based on the intensity of the first light source, thereby achieving precise control of the sleep mode of air conditioner 1.

[0051] In some embodiments, when the compressor is controlled to operate at a first preset frequency, or controlled to operate at a second preset frequency, or controlled to stop, based on at least one of the second operating time stage, the second light intensity, the second sound intensity, and the second operating duration, the controller 15 is configured to: control the compressor to operate at the second preset frequency when the second operating time stage is within the first preset operating time stage and the second light intensity is greater than the preset light intensity; or control the compressor to operate at the first preset frequency when the second operating time stage is within the first preset operating time stage, the second light intensity is less than the preset light intensity, the second sound intensity is less than the preset sound intensity, and the second operating duration is within the second preset duration range; or control the compressor to stop when the second operating time stage is within the first preset operating time stage, the second light intensity is less than the preset light intensity, the second sound intensity is less than the preset sound intensity, and the first operating duration is within the first preset duration range.

[0052] In this embodiment, the second preset duration range is the difference between the real-time time T1 of the air conditioner 1 during the first sleep stage and the initial running time T0 of the air conditioner 1, for example, denoted as T1-T0.

[0053] like Figure 3 As shown, when the air conditioner 1 is running in non-sleep mode, the second light intensity detected by the light sensor 13 is denoted as α2, and the second sound intensity detected by the sound sensor 14 is denoted as δ2. The controller 15 times the second running time of the air conditioner 1 in non-sleep mode, denoted as ΔT1. The controller 15 determines whether the second running time period is within the first preset running time period of 8:00-18:00, and whether the second light intensity α2 is equal to the preset light intensity α. 标 The relationship is as follows: if the second running time phase falls within the first preset running time phase (8:00-18:00), and the second light intensity α2 is greater than the preset light intensity α... 标 That is, α2 > α 标 Then, the compressor is controlled to run at the second preset frequency. By running the compressor at the normal frequency in non-sleep mode, the user's normal needs for air conditioner 1 during the day are guaranteed.

[0054] like Figure 4 As shown, when the second operating time phase of air conditioner 1 falls within the first preset operating time phase of 8:00-18:00, the intensity of the second light α2 is compared with the preset light intensity α. 标 The relationship between the second sound intensity δ2 and the preset sound intensity δ is determined. 标 The relationship between the two is determined, and it is determined whether the second running time ΔT1 is within the second preset time range T1-T0. If the second light intensity α2 is less than the preset light intensity α, then... 标 That is, α2 < α 标The second sound intensity δ2 is less than the preset sound intensity δ 标 That is, δ2 < δ 标 If the second running time △T1 is within the second preset time range T1-T0, i.e. △T1 < T1-T0, then the compressor is controlled to run at the first preset frequency to reduce energy consumption.

[0055] like Figure 5 As shown, when the second operating time phase of air conditioner 1 falls within the first preset operating time phase of 8:00-18:00, the intensity of the second light α2 is compared with the preset light intensity α. 标 The relationship between the second sound intensity δ2 and the preset sound intensity δ is determined. 标 The relationship between the two is used to determine whether the first running time ΔT2 is within the first preset time range T2-T0. If the second light intensity α2 is less than the preset light intensity α, then... 标 That is, α2 < α 标 The second sound intensity δ2 is less than the preset sound intensity δ 标 That is, δ2 < δ 标 If the first running time △T2 is within the first preset time range T2-T0, i.e. △T2 < T2-T0, then the compressor is controlled to stop.

[0056] In some embodiments, when the compressor is controlled to operate at a first preset frequency, or controlled to operate at a second preset frequency, or controlled to stop, based on at least one of the second operating time stage, the second light intensity, the second sound intensity, and the second operating duration, the controller 15 is configured to: control the compressor to operate at the second preset frequency when the second operating time stage is within the second preset operating time stage and the second light intensity is greater than the preset light intensity; or control the compressor to operate at the first preset frequency when the second operating time stage is within the second preset operating time stage, the second light intensity is less than the preset light intensity, the second sound intensity is less than the preset sound intensity, and the second operating duration is within the second preset duration range.

[0057] In an embodiment, such as Figure 6 As shown, when the air conditioner 1 is running in non-sleep mode, the second light intensity detected by the light sensor 13 is denoted as α2, and the second sound intensity detected by the sound sensor 14 is denoted as δ2. The controller 15 times the second running time of the air conditioner 1 in non-sleep mode, denoted as ΔT1. The controller 15 determines whether the second running time period is within the second preset running time period of 18:00-8:00, and determines whether the second light intensity α2 is equal to the preset light intensity α. 标 The relationship is as follows: if the second running time phase falls within the second preset running time phase of 18:00-8:00, and the second light intensity α2 is greater than the preset light intensity α... 标That is, α2 > α 标 Then, the compressor is controlled to run at the second preset frequency. By running the compressor at the normal frequency in non-sleep mode, the normal needs of the user for air conditioner 1 are guaranteed at night.

[0058] like Figure 7 As shown, when the second operating time phase of air conditioner 1 is within the second preset operating time phase of 18:00-8:00, the second light intensity α2 is compared with the preset light intensity α. 标 The relationship between the second sound intensity δ2 and the preset sound intensity δ is determined. 标 The relationship between the two is used to determine whether the second running time ΔT1 is within the second preset time range T1-T0. If the second light intensity α2 is less than the preset light intensity α, then... 标 That is, α2 < α 标 The second sound intensity δ2 is less than the preset sound intensity δ 标 That is, δ2 < δ 标 If the second running time △T1 is within the second preset time range T1-T0, i.e. △T1 < T1-T0, then the compressor is controlled to run at the first preset frequency to reduce energy consumption.

[0059] In some embodiments, after the compressor is stopped, the controller 15 is further configured to: after receiving a control command to start the air conditioner 1 again, control the air conditioner 1 to start again.

[0060] In this embodiment, when the air conditioner 1 is running in a non-sleep state and the controller 15 controls the compressor to stop, if the controller 15 receives a control command to start the air conditioner 1 again, it controls the compressor to restart to wake up the air conditioner 1.

[0061] In some embodiments, when the compressor is controlled to run at a first preset frequency, the controller 15 is configured to: determine whether the air conditioner 1 is in heating mode; if so, control the air conditioner 1 to run at a third preset frequency; otherwise, control the air conditioner 1 to run at a fourth preset frequency.

[0062] In this embodiment, when the compressor is controlled to run at a first preset frequency, it is determined whether the air conditioner 1 is in heating mode. If the air conditioner 1 is in heating mode, the compressor is controlled to run at a third preset frequency, that is, the compressor runs at 80% of the highest frequency for free heating operation. If the air conditioner is not in heating mode, that is, the air conditioner 1 is in cooling or dehumidifying mode, the compressor is controlled to run at a fourth preset frequency, that is, the compressor runs at 80% of the highest frequency for free cooling operation. By adjusting the operating frequency of the compressor according to the operating mode of the air conditioner 1, precise control can be achieved for different operating modes in the home environment.

[0063] In some embodiments, after the compressor is restarted, the controller 15 is configured to control the compressor to operate at a second preset frequency.

[0064] In this embodiment, after the air conditioner 1 is restarted, the controller 15 controls the compressor to run at a second preset frequency, that is, the compressor runs at the frequency of normal operation before entering the sleep state, and the backlight of the air conditioner 1 is turned on simultaneously to ensure the normal operation of the air conditioner 1. The backlight of the air conditioner 1 can also be used to indicate to the user that the air conditioner 1 has been restarted.

[0065] In some embodiments, when the air conditioner 1 is controlled to operate in a sleep state or in a non-sleep state according to the received light request and sound intensity, the controller 15 is configured to: control the air conditioner 1 to operate in a sleep state when the light intensity is less than a preset light intensity and the sound intensity is less than a preset sound intensity; and control the air conditioner 1 to operate in a non-sleep state when the light intensity is greater than a preset light intensity and the sound intensity is greater than a preset sound intensity.

[0066] In this embodiment, when the air conditioner 1 is powered on, the light sensor 13 detects the light intensity of the indoor environment in real time and sends the light intensity to the controller 15; the sound sensor 14 detects the sound intensity of the indoor environment in real time and sends the sound intensity to the controller 15. After receiving the light intensity and sound intensity, the air conditioner 1 determines the relationship between the light intensity and the preset light intensity, and the relationship between the sound intensity and the preset sound intensity. If the light intensity is less than the preset light intensity and the sound intensity is less than the preset sound intensity, it is considered that the light in the indoor space is weak and the sound is low, and the user may have entered a sleep state. In this case, the air conditioner 1 is controlled to operate in sleep mode, and the backlight of the air conditioner 1 is turned off simultaneously. If the light intensity is greater than the preset light intensity and the sound intensity is greater than the preset sound intensity, it is considered that the light in the indoor space is strong and the sound is loud, and the user may not have entered a sleep state. In this case, the air conditioner 1 is controlled to operate in non-sleep mode, and the backlight of the air conditioner 1 is turned on simultaneously. By judging the intensity of the light and sound in the indoor environment through the controller 15, the air conditioner 1 is controlled to enter the corresponding operating state, realizing precise control of the user's sleep scenario. The change of the backlight of the air conditioner 1 also prompts the user of the status change of the air conditioner 1.

By adjusting the compressor frequency or controlling the compressor to stop in the corresponding scenario, the unnecessary power consumption caused by forgetting to turn off the air conditioner when the air conditioner 1 enters sleep mode and the air conditioner backlight is off can be avoided, thereby saving power consumption without increasing hardware costs and improving user experience.

[0091] The following is for reference. Figure 9 This invention describes an energy-saving control method for an air conditioner according to an embodiment of the present invention.

[0092] like Figure 9 As shown, the energy-saving control method for an air conditioner according to an embodiment of the present invention includes at least steps S1-S4.

[0093] Step S1: Receive voice control commands or receive light intensity and sound intensity.

[0094] In this embodiment, when the air conditioner is powered on, the light sensor detects the light intensity of the indoor environment in real time and sends the light intensity to the controller, and the sound sensor detects the sound intensity of the indoor environment in real time and sends the sound intensity to the controller; at the same time, the controller queries the current time in the cloud.

[0095] Step S2: Control the air conditioner to operate in sleep mode or non-sleep mode according to the received voice control command or light and sound intensity.

[0096] In this embodiment, the controller controls the air conditioner to enter different operating states according to the above parameters. For example, depending on the light intensity and sound intensity, the controller controls the air conditioner to operate in sleep mode or non-sleep mode. Alternatively, the controller can receive voice control commands from the user and control the air conditioner to operate in sleep mode or non-sleep mode according to the voice control commands.

[0097] Step S3: Obtain the first operating time stage, first light intensity, first sound intensity and first operating duration of the air conditioner in sleep mode, and control the compressor to run at a first preset frequency, or control the compressor to run at a second preset frequency, or control the compressor to stop, based on at least one of the first operating time stage, first light intensity, first sound intensity and first operating duration.

[0098] In this embodiment, when the air conditioner is running in sleep mode, the controller acquires at least one of the following: a first running time phase, a first light intensity, a first sound intensity, and a first running duration. For example, the first running time phase is acquired based on the time in the cloud; the first light intensity is acquired based on the light intensity of the current indoor environment detected by a light sensor; the first sound intensity is acquired based on the sound intensity of the current indoor environment detected by a sound sensor; the time when the air conditioner enters sleep mode is recorded to acquire the first running duration; and after acquiring the above parameters, the controller controls the compressor to run at a first preset frequency, or controls the compressor to run at a second preset frequency, or controls the compressor to stop, based on one or more of the above parameters, so as to reduce the operating frequency of the compressor or control the compressor to stop when the backlight is off in sleep mode, thereby saving energy.

[0099] Step S4: Obtain the second operating time stage, second light intensity, second sound intensity, and second operating duration of the air conditioner in non-sleep state. Based on at least one of the second operating time stage, second light intensity, second sound intensity, and second operating duration, control the compressor to operate at a first preset frequency, or control the compressor to operate at a second preset frequency, or control the compressor to stop, wherein the first preset frequency is less than the second preset frequency.

[0100] In this embodiment, when the air conditioner is running in non-sleep mode, the controller acquires at least one of the following: a second operating time stage, a second light intensity, a second sound intensity, and a second operating duration. For example, the second operating time stage is acquired based on the time in the cloud; the second light intensity is acquired based on the light intensity of the current indoor environment detected by a light sensor; the second sound intensity is acquired based on the sound intensity of the current indoor environment detected by a sound sensor; the time when the air conditioner enters non-sleep mode is recorded to acquire the second operating duration; and after acquiring the above parameters, the controller controls the compressor to run at a first preset frequency, or controls the compressor to run at a second preset frequency, or controls the compressor to stop, based on one or more of the above parameters. By detecting the light intensity and sound intensity of the indoor environment, and combining this with the operating stage and operating duration of the air conditioner, the controller controls the air conditioner to enter the corresponding operating state, and controls the compressor to change its frequency or stop the compressor accordingly in different operating states, thereby achieving precise control of the indoor space by the air conditioner and improving the user experience.

[0101] According to the energy-saving control method of the air conditioner according to the embodiments of the present invention, the air conditioner is controlled to operate in a corresponding state based on the joint detection of light intensity and sound intensity by light sensor and sound sensor, or voice control command, and the operating stage and operating time of the air conditioner are obtained when the air conditioner is running in the corresponding state. Combined with the light intensity and sound intensity of the indoor environment, the compressor is controlled to run at different preset frequencies or the compressor is controlled to stop. This achieves more precise control of the air conditioner for sleep scenarios. By adjusting the compressor frequency or controlling the compressor to stop in the corresponding scenario, unnecessary power consumption caused by forgetting to turn off the air conditioner when it enters sleep mode and the air conditioner backlight is off can be avoided, thereby saving power consumption without increasing hardware costs and improving user experience.
