[0034] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0035] In the description of the present invention, “a plurality of” means two or more, and “a number of” means one or more.

[0036] Hereinafter, an air conditioner indoor unit 1 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0037] like Figure 1-Figure 3 As shown, the air conditioner indoor unit 1 according to an embodiment of the present invention includes a body 100 , a light sensor 110 and a sound module 120 .

[0038] The light sensor 110 is installed on the body 100, and the light sensor 110 is configured to detect the light intensity in the room. The sound module 120 is installed on the body 100 and connected to the light sensor 110. The sound module 120 is configured to obtain the indoor light intensity detected by the light sensor 110 and the current time coefficient, and determine whether to control the sound module 120 to switch to the sound sleep mode based on the indoor light intensity and the current time coefficient.

[0039] It should be noted that switching the sound module 120 to the sound sleep mode does not completely shut down the sound module 120, but only reduces the probability of the sound module 120 being awakened, and the sound module 120 can also receive sound signals and broadcast sounds.

[0040] According to the air conditioner indoor unit 1 of an embodiment of the present invention, by installing a light sensor 110 on the body 100, the light sensor 110 is configured to detect the light intensity in the room. It can be understood that when it is daytime, the user will be active indoors when he is not in the sleep period, and the light intensity in the room will be higher at this time. When it is nighttime, when the user needs to sleep, he usually turns off the lights, and the light intensity in the room will be lower at this time. Or when the user needs to sleep during the day, he usually draws the curtains to reduce the light intensity in the room to create a comfortable sleeping environment.

[0041] That is, the light sensor 110 can detect the real-time indoor light intensity, and use the indoor light intensity as a factor to determine whether the user is sleeping.

[0042] In addition, the sound module 120 is installed on the body 100 and connected to the light sensor 110. The sound module 120 is configured to receive sound signals, broadcast sounds, and obtain the light intensity and current time coefficient detected by the light sensor 110, and determine whether to control the sound module 120 to switch to the sound sleep mode based on the light intensity and current time coefficient in the room.

[0043] Among them, the current time coefficient can represent the current time range, and the current time range can be used as another factor to determine whether the user is sleeping. For example, after obtaining the current time coefficient, it is judged that the current time range is around 12 o'clock at night (i.e. 24 o'clock). At this time, the user is more likely to be in a sleeping state, and it is judged that the current time range is around 12 o'clock during the day (i.e. 12 o'clock). At this time, the user is less likely to be in a sleeping state.

[0044] Therefore, when the indoor light intensity and the current time coefficient measured by the light sensor 110 meet the requirements of the user's sleep scene, or one of the indoor light intensity and the current time coefficient meets the requirements of the user's sleep scene, the sound module 120 can determine that the user is in a sleep state at this time. The two factors are combined for judgment, that is, the user's current state is determined from two different dimensions, thereby improving the accuracy of the judgment. In this way, when the user is in a sleep state, the sound module 120 of the indoor air conditioner can automatically switch to the sound sleep mode, thereby reducing the chance of the voice module being mistakenly awakened, reducing the possibility of disturbing the user's sleep, and providing a better user experience.

[0045] In this way, the air-conditioning indoor unit 1 according to the embodiment of the present invention can automatically identify whether the user is in a sleeping state, which has the advantages of low probability of being woken up by mistake and good user sleeping experience.

[0046] In some specific embodiments of the present invention, Figure 1-Figure 3 As shown, the air conditioner indoor unit 1 further includes at least one of a remote control device 130 and a control panel 140. The remote control device 130 is configured to send a remote control signal to the body 100 to adjust the operating mode of the air conditioner indoor unit 1. The control panel 140 is mounted on the body 100 and is used to adjust the operating mode of the air conditioner indoor unit 1.

[0047] Thus, in some embodiments, the user can adjust the operating mode of the air conditioner indoor unit 1 by controlling the buttons on the remote control device 130. In other embodiments, the user can also control the operating mode of the air conditioner indoor unit 1 by directly touching the buttons on the control panel 140 of the air conditioner indoor unit 1.

[0048] Of course, the user can also adjust the operating mode of the air-conditioning indoor unit 1 by waking up the sound module 120 through voice. In this way, the air-conditioning indoor unit 1 has three controllable modes, which is more convenient for users to use.

[0049] The following describes a control method of the air conditioner indoor unit 1 according to an embodiment of the present invention with reference to the accompanying drawings. Figure 4 As shown, the control method of the air-conditioning indoor unit 1 includes:

[0050] Get the indoor light intensity and current time coefficient;

[0051] Determine whether to control the sound module 120 to switch to the sound sleep mode according to the indoor light intensity and the current time coefficient;

[0052] If so, the sound module 120 is controlled to switch to the sound sleep mode.

[0053] That is to say, the light sensor will obtain the indoor light intensity, and the sound module 120 will obtain the current time coefficient. When the combined result of the indoor light intensity and the current time coefficient measured by the light sensor 110 meets the requirements of the user's sleep scene, or one of the indoor light intensity and the current time coefficient meets the requirements of the user's sleep scene, the sound module 120 can determine that the user is in a sleep state at this time, and thus determine that the sound module 120 needs to be switched to sleep mode. In this way, when the user is in a sleep state, the sound module 120 of the indoor air conditioner can automatically switch to sleep mode, thereby reducing the chance of the voice module being mistakenly awakened, reducing the possibility of disturbing the user's sleep, and providing a better user experience.

[0054] Moreover, by combining the indoor light intensity and the current time coefficient, that is, determining the user's current state from two different dimensions, the accuracy of the judgment can be improved and the user experience can be better.

[0055] In this way, the control method of the air-conditioning indoor unit 1 according to the embodiment of the present invention can automatically identify the user's sleeping scene, which has the advantages of low probability of being woken up by mistake and good user sleeping experience.

[0056] In some specific embodiments of the present invention, Figure 4 and Figure 5 As shown, judging whether to control the sound module 120 to switch to the sound sleep mode according to the indoor light intensity and the current time coefficient includes:

[0057] Determine whether the sum of the indoor light intensity and the current time coefficient is not greater than a preset threshold;

[0058] If so, the sound module 120 is controlled to switch to the sound sleep mode.

[0059] For example, the weaker the indoor light intensity, the more suitable it is for sleeping. That is to say, the indoor light intensity when the user is sleeping is generally small, and the current time coefficient can be set to different values ​​according to different time periods. Then, a suitable threshold is determined based on the difference between the indoor light intensity and the current time system value when suitable for sleeping and the indoor light intensity and the current time system value during the non-sleep period. When the sum of the indoor light intensity and the current time coefficient is not greater than the preset threshold, it means that at least one of the indoor light intensity and the current time period is suitable for the user to sleep, so that the user can be judged to be in a sleeping state, and the sound module 120 can be switched to the sound sleep mode to avoid the sound module 120 being woken up by mistake, so as to improve the user's sleep experience.

[0060] In some specific embodiments of the present invention, Figure 4 、 Figure 6 and Figure 7As shown, 8:00-12:00 is set as the first time interval, 12:00-18:00 is set as the second time interval, 18:00-22:00 is set as the third time interval, and 22:00-8:00 is set as the fourth time interval, and the time coefficient corresponding to the first time interval is set to A, the time coefficient corresponding to the second time interval is set to B, the time coefficient corresponding to the third time interval is set to C, and the time coefficient corresponding to the fourth time interval is set to D.

[0061] Get the current time coefficient including:

[0062] Get the current time;

[0063] Comparing the current time with the first time interval, the second time interval, the third time interval, and the fourth time interval;

[0064] If the current moment belongs to the first time interval, the current time coefficient is A;

[0065] If the current moment belongs to the second time interval, the current time coefficient is B;

[0066] If the current moment belongs to the third time interval, the current time coefficient is C;

[0067] If the current time belongs to the fourth time interval, the current time coefficient is D.

[0068] It is understandable that according to human sleeping habits, the 24 hours of a day can be divided into four time intervals, corresponding to the morning, afternoon, evening to night, and night to early morning. The time coefficient in the same time interval can be a constant value.

[0069] In this way, within the same time interval, the time coefficient remains unchanged, and only the change in indoor light intensity is relied upon to determine whether the sound module 120 needs to be switched to the sound sleep mode. For example, the user turns on the light to sleep at night, or draws the curtains to sleep during the day. At this time, the change in indoor light intensity will be large, but the time coefficient corresponding to the time interval may not change in a short time. The air-conditioning indoor unit 1 can determine that the user has performed operations suitable for sleeping, such as turning on the light or drawing the curtains, based on the change in indoor light intensity, so that the sum of the indoor light intensity and the current time coefficient drops to a range not greater than the preset threshold, so as to switch the sound module 120 to the sound sleep mode, thereby avoiding the sound module 120 being woken up by mistake.

[0070] Furthermore, D<C<A<B.

[0071] Specifically, the time coefficient D corresponding to the fourth time interval 22:00-8:00 is less than the time coefficient C corresponding to the third time interval 18:00-22:00 is less than the time coefficient A corresponding to the first time interval 8:00-12:00 is less than the time coefficient B corresponding to the second time interval 12:00-18.

[0072] It is understandable that the fourth time interval is from late night to early morning, which is the sleep period for most people, the third time interval is the sleep period for a small number of users who go to bed early, the first time interval is the sleep period for a small number of users who get up late, and the second time interval is in the afternoon, when users usually sleep less.

[0073] With this setting, the time coefficient corresponding to the fourth time interval is the smallest, and the sum of the indoor light intensity and the current time coefficient is unlikely to exceed the preset threshold, so that the sound module 120 can switch to the sound sleep mode. The time coefficients corresponding to the remaining three time intervals are greater than the time coefficient corresponding to the fourth time interval. That is to say, in the remaining three time intervals, the indoor light intensity plays a more important role in determining whether the user is in a sleeping state than the current time coefficient, thereby avoiding the chance of misjudgment by the sound module 120 and providing a better user experience.

[0074] In some specific embodiments of the present invention, Figure 4 and Figure 8 As shown, controlling the sound module 120 to switch to the sound sleep mode includes:

[0075] Send a signal to reduce the brightness of the background light;

[0076] Lower the volume of the announcement of the sound module 120.

[0077] Reducing the brightness of the backlight can be done by dimming it or turning it off directly to prevent it from affecting the user's sleep. Simultaneously, the volume of the announcements from the sound module 120 can be reduced. Even if the user accidentally wakes up the sound module 120, the volume of the announcements from the sound module 120 can be kept low, thereby reducing the chance of waking the user and further improving the user's sleep experience.

[0078] In some specific embodiments of the present invention, Figure 4 and Figure 9 As shown, controlling the sound module 120 to switch to the sound sleep mode includes:

[0079] Acquiring external sound signals;

[0080] Determining whether the signal-to-noise ratio of the external sound signal is greater than a first preset signal-to-noise ratio threshold;

[0081] If yes, control the sound module 120 to exit the sound sleep mode and control the sound module 120 to make an announcement;

[0082] If not, the external sound signal is filtered.

[0083] In this way, when the user is in a sleeping state, the ambient noise in the room decreases, and the ratio of the sound signal and noise emitted by the user's normal speech will be larger. Therefore, only when the ratio of the external sound signal to noise is larger will the sound module 120 be controlled to exit the sound sleep mode and control the sound module 120 to broadcast. When the ratio of the external sound signal to noise is small, the sound module 120 will not be woken up, thereby avoiding the sound module 120 from broadcasting and reducing the chance of the sound module 120 being woken up by mistake.

[0084] In some specific embodiments of the present invention, Figure 4 and Figure 10 As shown, after controlling the sound module 120 to exit the sound sleep mode, the following steps are performed:

[0085] Acquiring external sound signals;

[0086] Determining whether a signal-to-noise ratio of the external sound signal is greater than a second preset signal-to-noise ratio threshold, and the second preset signal-to-noise ratio threshold is less than the first preset signal-to-noise ratio threshold;

[0087] If yes, control the sound module 120 to make an announcement;

[0088] If not, the external sound signal is filtered.

[0089] That is to say, when the sound module 120 is not in the sound sleep mode, the second preset signal-to-noise ratio threshold can be smaller. At this time, the sound module 120 can be awakened when the ratio of the external sound signal to the noise is smaller, so that the user can adjust the operating mode and operating parameters of the air-conditioning indoor unit 1 through the sound module 120, and the operation is more convenient and quick.

[0090] Among them, it is understandable that when the user is not in a sleeping state, the ambient noise in the room may be relatively large, such as the sound of a mobile phone, the sound of a movie or TV player, or external noise such as footsteps. At this time, the user sends a sound signal to control the sound module 120, and the ratio of the sound signal to the noise will be relatively small. When the user is in a sleeping state, the ambient noise in the room decreases, and the ratio of the sound signal to the noise emitted by the user's normal speech will be relatively large. Therefore, by setting the first preset signal-to-noise ratio threshold and the second preset signal-to-noise ratio threshold to be different, and by setting the second preset signal-to-noise ratio threshold to be lower than the first preset signal-to-noise ratio threshold, it is possible to facilitate the voice control of the voice module of the air-conditioning indoor unit 1 when the user is not in a sleeping state, and to avoid the user from accidentally waking up the sound module 120 of the air-conditioning indoor unit 1 when sleeping.

[0091] In some specific embodiments of the present invention, Figure 11 As shown, the control method of the air-conditioning indoor unit 1 includes:

[0092] Get the current operating mode of air conditioner indoor unit 1;

[0093] Determine whether the current operating mode is sleep mode;

[0094] If yes, control the sound module 120 to switch to the sound sleep mode;

[0095] If not, the indoor light intensity and the current time coefficient are obtained, and then it is determined whether to control the sound module 120 to switch to the sound sleep mode according to the indoor light intensity and the current time coefficient.

[0096] Specifically, the air-conditioning indoor unit 1 also has a sleep mode. For example, the user can directly adjust the air-conditioning indoor unit 1 to the sleep mode through the remote control device 130, the control panel 140 or voice control. This means that the user needs to sleep. After the voice module detects that the air-conditioning indoor unit 1 has entered the sleep mode, the voice module can also directly enter the sound sleep mode. When the air-conditioning indoor unit 1 is in the sleep mode, the air outlet speed and temperature of the air-conditioning indoor unit 1 will be adjusted accordingly to keep the user comfortable during sleep.

[0097] However, the user may forget to put the air conditioner indoor unit 1 into sleep mode before going to sleep or simply do not put the air conditioner indoor unit 1 into sleep mode. At this time, the sound module 120 will comprehensively judge whether the user is sleeping based on the indoor light intensity and the current time coefficient, and thus judge whether it is necessary to control the sound module 120 to switch to the sound sleep mode, thereby reducing the chance of the sound module 120 being woken up by mistake and further improving the user's sleep experience.
