[0002] An air conditioner, that is, an air conditioner (Air Conditioner), refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air environment in a building or structure.

[0003] An air conditioner generally includes a cold source / heat source device, a cold and heat medium distribution system, a terminal device and other auxiliary devices. It mainly includes a refrigeration host, a water pump, a fan and a pipeline system.

An air conditioner generally includes an outdoor unit and an indoor unit connected to the outdoor unit. In the operating state, the fans of the outdoor unit and the indoor unit will keep running, and the operation will inevitably generate certain noise.

[0040] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art. Obviously, the drawings in the following description are only the embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained according to the provided drawings.

[0042] Figure 2 It is a schematic structural diagram of the check valve module disclosed in the embodiments of the present application;

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0046] White noise is a random signal or random process with a constant power spectral density over wavelength. In other words, the power of this signal is the same across all frequency bands. Since white light is composed of monochromatic lights of various frequencies (colors), the property of this signal having a flat power spectrum is called "white", and thus this signal is called white noise.

[0047] In some countries, many people who have received white noise therapy describe it as sounding like the sound of rain, or the sound of waves crashing against rocks, or the rustling sound of the wind blowing through the leaves, or the sound of a mountain stream or waterfall. This kind of sound can play a certain role in sound therapy for people of all age groups and is a "harmonious" therapeutic sound. Some people also feel that "white noise" has a somewhat natural atmosphere, and white noise at a certain volume can cure the attention deficit disorder of some hyperactive children. In short, under certain circumstances, certain white noises can make the human body feel comfortable.

[0048] Therefore, in order to provide users with good sleep quality, in this solution, an air conditioner control method is disclosed. By detecting the indoor noise in real time, comparing the detected noise curve with a preset white noise curve, and based on the comparison result, using the noise generated when the fresh air system works to compensate the indoor noise, so that the indoor noise can achieve an effect similar to white noise, thereby improving the user's sleep quality.

[0049] See Figure 1 , the embodiments of this application disclose an air conditioner control method, and this method may include: steps S101 - S107.

[0050] Step S101: Obtain the indoor environmental noise in real time.

[0051] In this step, a sound collection device can be configured on the indoor unit or at other positions in the room, and the indoor environmental noise is collected in real time through the sound collection device.

[0052] In the technical solution disclosed in the embodiments of this application, this solution is mainly used to assist users in sleeping. Therefore, this solution is mainly executed when the user is sleeping. In this solution, it is possible to detect whether the user enters the sleeping state by detecting the indoor light intensity. Specifically, when the detected indoor light intensity is lower than the preset value, it indicates that the user enters the sleeping state. At this time, control the air conditioner system in the on state to load and execute the air conditioner control method disclosed in the embodiments of this application. When the indoor light intensity is greater than the preset value, without obtaining a control instruction input by the user to actively execute this method, this solution does not need to be executed.

[0053] Step S102: Calculate the proportion of the indoor environmental noise being white noise within a preset duration.

[0054] In this step, it is determined whether each piece of indoor environmental noise obtained within a period of time is white noise, and the proportion of the number of pieces of white noise recognized within this period of time is calculated.

[0055] Step S103: Determine whether the proportion is less than a preset ratio.

[0056] In this step, a preset ratio is set in advance. Whether the indoor environmental noise is white noise is judged by this ratio. If the indoor environmental noise itself is white noise, then there is no need to adjust the magnitude of the indoor environmental noise. In this solution, if this proportion is greater than the preset ratio, it is considered that the indoor environmental noise itself is white noise. This preset ratio is a preset value. For example, it can be any value such as 90% or 95%.

[0057] For example, when it is raining, the indoor environmental noise itself can be regarded as white noise. At this time, there is no need to adjust the magnitude of the indoor noise.

[0058] Step S104: Obtain the white noise corresponding to the indoor environmental noise in the target white noise curve.

[0059] In this solution, a continuous white noise curve can be pre-configured. This white noise curve is denoted as the target white noise curve. The target white noise curve can be a white noise curve obtained by repeatedly splicing a section of white noise curve, or a randomly generated white noise curve. When it is detected that the indoor environmental noise is not white noise, when the indoor environmental noise is detected again, the white noise in the target white noise curve corresponding to this moment is obtained. The moments corresponding to each white noise point in the target white noise curve are arranged in sequence on the time axis.

[0060] In this solution, the white noise refers to the white noise that matches the moment of the obtained indoor environmental noise.

[0061] Step S105: Calculate the difference between the indoor environmental noise at this moment and the white noise.

[0062] In this step, after obtaining the indoor environmental noise and the corresponding white noise, the noise difference between the two is calculated.

[0063] Step S106: Turn on the fresh air system.

[0064] In this step, when it is determined that the indoor environmental noise is not white noise, the fresh air system is turned on. In this solution, mainly the noise generated by the fresh air system is used to compensate the indoor environmental noise so that the compensated indoor environmental noise is equivalent to white noise.

[0065] Step S107: Based on the difference between the obtained indoor environmental noise and white noise, adjust the air output volume and the fan speed of the fresh air system so that the difference between the indoor environmental noise and white noise is within a preset difference.

[0066] In this solution, after calculating the difference between the indoor environmental noise and white noise, based on a preset mapping relationship, obtain the fan speed and fresh air output volume of the fresh air system corresponding to the difference, and then control the fresh air system based on the fan speed and fresh air output volume, so that the difference between the indoor environmental noise and white noise is within a preset difference. When the difference between the indoor environmental noise and white noise is within the preset difference, it can be considered that the indoor environmental noise is white noise, thereby improving the user's sleep quality.

[0067] In addition to adjusting the indoor environmental noise through the fresh air system, the indoor environmental noise can also be compensated by adjusting the air conditioner wind speed and the operating state of the air conditioner. The reason why this application does not compensate for the indoor environmental noise by adjusting the air conditioner wind speed and the operating state of the air conditioner is that if the air conditioner wind speed and operating state are changed, it will inevitably affect the air conditioner wind speed, set temperature, etc., and further affect the user's use. Therefore, based on the above considerations, this application compensates for the indoor environmental noise through the fresh air system, so that it is not necessary to change the cooling, heating state and target temperature of the air conditioner set by the user.

[0068] In order to adjust the wind speed at the fresh air inlet of the air conditioner, in this solution, a check module is provided in the fresh air duct of the fresh air system. The size of the ventilation port of the check module is adjustable, and the size of the ventilation port of the check module can be adjusted according to the corresponding control instruction, so as to adjust the size of the air output volume of the fresh air system.

[0069] See Figure 2 , the check module includes a base 01, a housing 02, a V-shaped rubber tube 03, and a spring 04; the base 01 is provided with a first thread and a second thread. The base 01 is threadedly connected to the fresh air plastic tube forming the fresh air duct through the first thread. The housing 02 is threadedly connected to the base 01 through the second thread on the base 01. The housing 02 is used to support the V-shaped rubber tube 03. The V-shaped rubber tube 03 is installed in the housing 02, and the tapered end of the V-shaped rubber tube 03 faces the air outlet of the fresh air duct. The spring 04 is arranged inside the tapered end of the V-shaped rubber tube 03 and is used to support the tapered end of the V-shaped rubber tube 03. When the spring 04 extends, the tapered end of the V-shaped rubber tube 03 expands. When the spring 04 contracts, the tapered end of the V-shaped rubber tube 03 shrinks. The expansion and contraction of the spring 04 are controlled by a target motor. By controlling the rotation direction of the target motor, the extension or contraction of the spring 04 can be controlled.

[0070] Specifically, adjusting the size of the ventilation opening of the check valve module includes:

[0071] Obtain the air volume adapted to the difference between the indoor environmental noise and the white noise, determine the corresponding motor control command based on the air volume, the motor control command includes the motor rotation angle and the motor rotation direction, and control the target motor based on the motor control command so that the target motor rotates by the corresponding angle in the rotation direction under the control of the motor control command; Since the transmission shaft of the target motor is connected to the spring through a transmission mechanism, when the transmission shaft of the target motor rotates in the first direction, the spring is stretched through the transmission mechanism, and when the transmission shaft of the target motor rotates in the second direction, the spring is contracted through the transmission mechanism. The spring is arranged at the end of the V-shaped rubber tube of the check valve module. When the spring elongates, the opening at the end of the V-shaped rubber tube increases, and the air volume output by the fresh air system becomes larger. When the spring contracts, the opening at the end of the V-shaped rubber tube decreases, and the air volume output by the fresh air system becomes smaller.

[0072] In the technical solution disclosed in another embodiment of the present application, since the habits of different users are different, the types of white noise that can assist their sleep may also be different. In this solution, white noise curves of corresponding types can be pre-configured for different users, and a mapping relationship between different users and different white noise curves can be established. When implementing the above solution disclosed in the embodiment of the present application, the users in the room can be pre-identified, and the target white noise curve used in this solution can be determined based on the identification result. Therefore, in the above solution, before obtaining the white noise in the target white noise curve corresponding to the indoor environmental noise, it further includes: identifying the target user in the area covered by the air conditioner through the identification module, and obtaining the white noise curve matching the target user from multiple pre-stored white noise curves as the target white noise curve.

[0073] In the technical solution disclosed in another embodiment of the present application, if there are multiple target users in the room, especially when there are child users or elderly users, it is necessary to give priority to ensuring the sleep of child users or elderly users. Therefore, in this solution, corresponding priorities are pre-configured for these users, and the sleep of the user with the highest priority is preferentially ensured. At this time, the step of obtaining the white noise curve matching the target user from multiple pre-stored white noise curves as the target white noise curve specifically includes:

[0074] If it is detected that there are multiple users in the room and multiple users all correspond to pre-stored white noise curves, obtain the priorities of the respective target users, and obtain the white noise curve of the target user with the highest priority from multiple pre-stored white noise curves as the target white noise curve.

[0084] Generate a motor control instruction, so that the target motor rotates a specific number of turns under the control of the motor control instruction.
