Application content

In order to solve at least one of the above technical problems, an object of the present application is to provide an operation control method.

Another object of the present application is to provide an operation control device.

Another object of this application is to provide an air conditioner.

Another object of this application is to provide a computer-readable storage medium.

In order to achieve the foregoing objective, the embodiment of the first aspect of the present application provides an operation control method, including: detecting body shape feature information and location distribution information of users in a target area; and controlling according to the body shape feature information and location distribution information The upper inner machine air outlet assembly performs narrow-angle air supply to the target area, and controls the lower air outlet opening and closing mechanism to shield the lower air outlet, so as to reduce the air output of the lower inner machine air outlet assembly, wherein , The distance between the air outlet assembly of the upper internal machine and the bottom of the air conditioner is greater than the distance between the air outlet assembly of the lower internal machine and the bottom of the air conditioner; in addition, the narrow-angle air supply is performed When the air outlet assembly of the upper internal machine is blown in a specified direction, it will spread out when it reaches a specified distance, and the specified distance corresponds to the rotation speed of the air outlet assembly of the upper internal machine.

In this solution, the target area is for the air conditioner, which usually includes the area that can be detected by the sensor on the air conditioner, as well as the area affected by the operation control parameters. Therefore, by detecting the body shape feature information of the user in the target area And location distribution information, narrow-angle air supply is helpful to improve the user experience.

Specifically, the user's body shape feature information can determine the user's identity and user group to which he belongs, and according to the body shape feature information and the position distribution information, the upper internal machine air outlet assembly is controlled to provide narrow-angle air supply to the target area , The air conditioner can send the air to the target area farther away when the air outlet component of the upper internal unit performs narrow-angle air supply, and there is almost no wind dissipation near the air conditioner. Therefore, the narrow-angle air supply can not only avoid the specified The user group can also effectively ensure the effect of adjusting the temperature and/or humidity of the target area.

After controlling the air outlet of the upper inner machine to deliver narrow-angle air to the target area, the air outlet of the air outlet of the lower inner machine is controlled to decrease, that is, the air volume of the air outlet of the lower inner machine is reduced by mechanical shielding. The air outlet of the inner unit is closer to the bottom of the air conditioner. Therefore, for designated user groups such as the elderly, infants and pregnant women, when they are close to the air conditioner, the distance from the air outlet of the lower inner unit is the closest. The air output of the air outlet of the machine is beneficial to enhance the windless experience of the aforementioned users.

It is worth noting that the first fan and the second fan in the air outlet assembly of the lower internal machine are both axial flow fans (or diagonal flow fans), and the blades of the first fan and the second fan can be rotated in a counter-rotating manner. Setting, in order to reduce the air output of the air outlet components of the lower internal machine, the speed of the first fan and the second fan can be controlled to reduce (including shutdown), or the first fan can be controlled to stop, at the same time, the second fan can be controlled to reduce the speed, or the second fan can be controlled to reduce the speed. The first fan and the second fan operate in a counter-rotating manner, and the speeds of the first fan and the second fan are lower than a certain speed threshold. The speed of the first motor, the speed of the second motor and the speed threshold are all based on the air conditioner The size of the fan assembly is determined.

In addition, the third fan and the fourth fan in the air outlet assembly of the upper internal machine are both axial fans (or diagonal fans). The third fan and the fourth fan work together to achieve narrow-angle air supply, thereby expanding the air supply. Wind distance to improve the effect of the air conditioner on adjusting the temperature and/or humidity of the target area.

Specifically, any axial fan can rotate in the first direction, that is, blowing toward the evaporator, and any axial fan can also rotate in the second direction (opposite to the first direction), that is, blowing toward the air outlet of the internal machine. When performing narrow-angle air supply to the target area, usually adjust the speed of the third fan to be greater than or equal to the speed of the fourth fan, and/or adjust the difference between the speed of the third fan and the speed of the fourth fan to be less than or equal to a speed difference When the threshold is set, the effect of gathering wind can be achieved, that is, narrow-angle blowing is performed to the target area, and the wind is sent to the target area further away, thereby improving the temperature control efficiency of the air conditioner to the target area.

In addition, the operation control method in the foregoing embodiment provided by this application may also have the following additional technical features:

In the above technical solution, detecting the body shape feature information and location distribution information of the user in the target area specifically includes: collecting image information in the target area, and/or collecting sound information in the target area, and/or using Infrared radio frequency detection is used to determine the body shape feature information and location distribution information of the user in the target area, where the body shape feature information includes the user's height information and/or body width information, and the location distribution information includes all The distance between the user and the air conditioner and the distribution area of the user are described.

In this solution, the image information is used to extract the user's gait feature information, face feature information, and body contour feature in the target area, but is not limited to this. Therefore, based on the image information, interfering objects, such as furniture, Accessories, movable home appliances, pets, lamps, etc., but not limited to this. Therefore, by collecting image information in the target area, on the one hand, after identifying the user's identity or user group, combined with location distribution information to narrow the angle Air supply is conducive to improving the user experience. On the other hand, when there is no user in the target area, there is no need to adjust the operating parameters of the air conditioner, or directly control the air conditioner to stop, so as to reduce the power consumption and hardware of the air conditioner loss.

(1) Gait feature information mainly includes the posture characteristics of the user during walking, which can include the frequency and amplitude of leg movements, the frequency and amplitude of swinging arms, the body trend, the walking speed and the step amplitude, etc., but it is not limited to this. State recognition is to recognize the above posture features to identify the user’s identity information. When the gait feature information is detected, the distance between the user and the internal unit of the air conditioner can be greater than a certain distance (for example, 4 meters away). It is mainly used to distinguish user groups such as the elderly, infants and adults, and there is no requirement for the user's posture.

(2) The facial feature information mainly includes the user's facial features, three-dimensional shape, wrinkle texture, skin color, etc., but not limited to this. When the facial feature information is detected, the distance between the user and the internal unit of the air conditioner is usually less than A certain distance (for example, within 4 meters), and the user's face is required to face the camera on the air conditioner, but the facial feature information can be used to detect the user's identity with high accuracy.

(3) The body contour feature information is used to determine the user's height information and/or body width information, but not limited to this, the height information can be used to distinguish between adult users and designated users, and the body width information can be used to identify pregnant users.

In addition, the sound information is used to extract the user’s voiceprint feature information. Specifically, the voiceprint feature information mainly includes the sound wave spectrum included in the sound information detected by the electroacoustic instrument. There are significant differences in length, timbre, and tone intensity. Therefore, the waveform of the collected sound information is reflected in the differences in wavelength, frequency, amplitude and rhythm. When the sound information is converted into a spectral graph, the above-mentioned voiceprint characteristics are obtained. It has the same role of identification as fingerprints.

Finally, the infrared radio frequency detection method is usually to send an infrared signal to the target area and receive the reflected infrared signal. Because the penetration ability of the infrared signal is poor, and the propagation speed and the propagation direction are known, the infrared signal can communicate with the The time difference between the reflected infrared signals determines the body shape feature information and location distribution information of the user in the target area, and then combines the user's body shape feature information and location distribution information for narrow-angle air supply, thereby improving the user experience.

In the above technical solution, according to the body shape feature information and the position distribution information, controlling the upper internal machine air outlet assembly to supply narrow-angle air to the target area includes: When one of the users is a designated user, the distance between the designated user and the air conditioner is detected; and the air outlet assembly of the upper internal machine is controlled to provide narrow-angle air supply according to the distance.

In this solution, by detecting the distance between the designated user and the air conditioner, it is possible to provide narrow-angle air supply to the target area. Usually, when the designated user is close to the air conditioner, the narrow-angle air supply is performed, in order to blow The wind blows to the farther target area, thereby reducing the spread of the blown wind near the cabinet. Therefore, the blowing sensation of designated users near the air conditioner can be reduced.

In addition, when the air outlet assembly of the upper internal machine performs narrow-angle air supply to the target area, the air supply direction of the air outlet assembly of the upper internal machine can be adjusted at the same time, that is, the wind direction of the narrow-angle air supply can be further adjusted to further reduce Specify the blowing feeling of the user, where the wind guide component usually includes a wind guide plate, a wind guide blade, and a wind guide strip, but not limited to this.

Wherein, the air supply direction of the air outlet assembly of the upper internal machine can be adjusted in combination with the detected height information of the user. The air supply direction depends on the angle between the air guide assembly and the horizontal line, and the angle between the angle and the height information It is a positive correlation, which means that the ratio between the angle and the elevation information is positive, such as linear positive correlation or nonlinear positive correlation.

Specifically, when narrow-angle air is supplied to the target area through the upper internal machine air outlet component, the air supply direction is adjusted upwards, which can assist the narrow-angle air supply to the wind direction diagonally upward, in addition, combined with the height information of the designated user To adjust the angle between the wind guide component and the horizontal line can improve the efficiency and reliability of wind direction adjustment. For example, the designated users are usually infants, young children, the elderly, and pregnant women. Take Table 1 as an example to illustrate the difference between the user’s height information and the included angle. Relationship.

In the above technical solution, controlling the axial flow fan to perform narrow-angle air supply according to the distance specifically includes: determining whether the distance is less than or equal to a distance threshold; if it is determined that the distance is less than or equal to the distance threshold, determining The axial flow fan is controlled to supply air with a narrow angle.

In this solution, by judging that the distance is less than or equal to the distance threshold, the axial flow fan is controlled to provide narrow-angle air supply, which can effectively prevent the blown air from spreading near the cabinet to reduce users near the air conditioner (for example, users The distance between the air conditioner and the air conditioner is less than 1 meter). At the same time, since the blowing wind is not weakened and can be blown to the target area farther, it is beneficial to increase the temperature and/or humidity in the target area. The effect of regulation.

In the above technical solution, if the upper internal machine air outlet assembly is controlled to supply narrow-angle air to the target area, controlling the lower air outlet opening and closing mechanism to block the lower air outlet specifically includes: controlling the upper air outlet If the inner machine air outlet component delivers narrow-angle air to the target area, the displacement of the lower air outlet opening and closing mechanism is adjusted according to the distance, wherein the distance between the opening and closing degree of the lower air outlet is Positive correlation.

For example, when the user is close to the air conditioner (for example, within 1 meter), the lower air outlet is controlled to be completely closed, and at the same time, the air outlet components of the inner machine are controlled to stop working completely. .

Wherein, the ratio between the distance and the opening and closing degree of the lower air outlet is a positive number, for example, a linear positive correlation or a nonlinear positive correlation.

In the above technical solution, the lower internal machine air outlet assembly is provided with a first fan and a second fan, the first fan is arranged close to the evaporator of the air conditioner, and the second fan is arranged close to the lower air outlet If the upper inner machine air outlet assembly is controlled to provide narrow-angle air supply to the target area, the lower air outlet switch mechanism is controlled to block the lower air outlet, so as to reduce the output of the lower inner machine air outlet assembly.

There is a positive correlation between the speeds.

In this solution, if the upper internal machine air outlet assembly is controlled to provide narrow-angle air supply, on the one hand, the air supply distance of the upper internal machine air outlet assembly will increase. This air supply distance also depends on the fan size and fan speed, such as , The air supply distance is more than 2.5 meters. On the other hand, when the air outlet assembly of the upper internal machine is used for narrow-angle air supply, the wind will not spread near the air conditioner. Therefore, there is no need to lower the output of the air outlet assembly of the upper internal machine. The air volume can further improve the efficiency of the air conditioner for temperature control of the target area, and at the same time, can reduce the blowing sensation of designated users near the air conditioner.

In addition, by controlling the speed of the first fan to decrease or blow to the evaporator according to the degree of opening and closing, and/or controlling the speed of the second fan to decrease or blow to the evaporator according to the degree of opening and closing, that is, reducing the opening and closing degree of the lower air outlet At the same time, combined with the opening and closing degree to reduce the fan speed of the air outlet assembly of the lower inner machine, or through the counter-rotation of the first fan and the second fan, not only further reduces the air output of the air outlet of the lower inner machine, but also reduces the output of the lower inner machine. The power consumption of the wind component, the above-mentioned operation control scheme can effectively reduce the blowing sensation of users with lower heights, such as the elderly, infants and pregnant women, but not limited to this.

Finally, because the upper inner machine blowing component and the lower inner machine blowing component are independently controlled, the upper inner machine blowing component can improve the effect of temperature and/or humidity control on the target area by means of narrow-angle air supply. The blower assembly of the lower inner machine can be completely stopped, and the lower air outlet is completely closed.

Wherein, the ratio between the rotation speed of the blowing assembly of the lower inner machine and the opening and closing degree of the lower air outlet is a positive number, for example, a linear positive correlation or a nonlinear positive correlation.

In this solution, if the upper inner unit air outlet component is controlled to provide narrow-angle air supply, and the lower air outlet needs to be reduced to reduce the air output of the lower inner unit air outlet, in order to reduce the power consumption of the air conditioner, it is necessary to The rotation speed of the first fan and the rotation speed of the second fan are restricted.
