Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic flow chart of an air supply control method according to an embodiment of the present application, where the method may be applied to an air supply device, and as shown in fig. 1, the air supply control method specifically includes steps S101 to S103.

S101, detecting a door and a window in an open state in a room through a door and window detection device, and determining the opening duration of the door and the window in the open state.

The doors and windows are building structures for allowing users to enter rooms, enabling air in the rooms to flow with outside air or enabling the rooms to collect light, and the doors and windows may include doors and/or windows, some rooms are provided with the doors and/or windows at the same time, some rooms are provided with the doors and the windows, and the doors and the windows are omitted, and the doors and the windows are specifically determined according to the room structures in practical application.

Doors and windows generally include two states: an open state and a closed state; the doors and windows in the closed state prevent air in the room from circulating with outside air, and if the doors and windows in the room are in the closed state for a long time, the air quality in the room is deteriorated. The door and window in the open state enables air in the room to be convected with air outside through the door and window, and fresh air outside is injected into the room, so that the air in the room can be kept fresh.

The door and window generally comprises a door and window body and a fixed frame, wherein the door and window body is in a closed state and is buckled on the fixed frame; and the door and window body is separated from the fixed frame when the door and window is in an open state. The door and window detection device can be arranged on the door and window body and/or the fixed frame and used for detecting the position relation of the door and window body and the fixed frame so as to determine whether the door and the window are in an opening state or not.

Exemplarily, door and window detection device includes distance sensor, and distance sensor includes signal transmission end and signal receiving terminal, and signal transmission end and signal receiving terminal set up respectively on door and window body and fixed frame, and distance sensor can detect the distance between door and window body and the fixed frame, if the distance is greater than a definite value, then judges that door and window is in the open mode.

The opening duration of the door and window in the open state may be the accumulated time of the door and window in the open state at this time, that is, the accumulated time of the door and window in the open state after the previous closed state is switched to the current open state.

In one embodiment, the determining the opening duration of the door window in the open state may be performed by: determining the opening time of the door and window when the door and window is switched from a closed state to an open state; and determining the opening duration of the door and window in the opening state according to the opening time and the current time.

And S102, if the opening time is longer than or equal to the preset time, detecting the air quality parameter in the room through an air detection device.

The air quality parameters comprise physical, chemical, biological and radioactive related parameters related to human health, and also comprise parameters for evaluating the air quality, and the air quality can be evaluated according to national standards. The air detection device may be a device for detecting an air quality parameter, illustratively, the air quality parameter includes a carbon dioxide concentration, and the air detection device includes a carbon dioxide detector.

After the door and window are opened for a certain time, if the outside air has a certain flow value, the outside air can flow into the room through the door and window, and then the air quality in the room can be optimized. However, if the outside air flow value is low, the outside air does not flow into the room, and the air quality in the room may not be improved.

Therefore, the air quality parameter in the room can be detected through the air detection device, so that when the air quality in the room is not improved after the door and the window are opened for a certain time, the air flow is generated in the room through the air supply device, and the convection of the air in the room and the air outside the room is enhanced.

And S103, starting the air supply device according to the air quality parameters in the room so that the air supply device supplies air in the room.

After the air quality parameters in the room are determined, the air quality in the room can be determined according to the air quality parameters in the room, and the air supply device can be started if necessary so as to enable the air supply device to supply air in the room.

The air supply device is a device for generating wind force to accelerate air flow in a room, the air supply device can be a circulating fan, the circulating fan generally comprises a fan and a flow guide component, the wind generated by the fan can be transmitted out through the flow guide component to be blown out spirally along a certain direction to form spiral columnar wind, therefore, the wind of the circulating fan can be transmitted to a longer distance, and when the circulating fan supplies the wind in the room, the air in the room can form convection circulation to enhance the air flow in the room.

According to the embodiment of the application, the air quality parameters in the room are detected after the door and the window are opened for a certain time, the air quality in the room is determined according to the air quality parameters, and the air supply device can be started when necessary, so that the air supply device supplies air in the room, the convection of the air in the room and the outside air is enhanced, and the air quality in the room is improved.

In one embodiment, as shown in fig. 2, the activating the air supply device in the room according to the air quality parameter in the room may be implemented by:

s111, comparing the air quality parameters in the room with target air information to obtain a comparison result;

and S112, if the comparison result meets the ventilation condition, starting an air supply device in the room.

The target air information may include an air quality parameter that represents that the air quality is qualified, and may include a standard air quality parameter, and the standard may not affect human health. The air quality parameters in the room are compared with the target air information, whether the air quality in the room is qualified or not can be determined, and the condition that the air in the room can not affect the human health is determined. Illustratively, the air quality parameters in the room and the parameters contained in the target air information may be compared one by one to obtain a comparison result.

The ventilation condition may be a condition for determining whether the air quality in the room is qualified, and if the comparison result meets the ventilation condition, it indicates that the air quality in the room is not qualified, or the human health is affected, so that the air supply device needs to be started to perform circulating convection on the air in the room, so as to optimize the air quality in the room.

In one embodiment, if the comparison result includes that the air quality parameter in the room is worse than the target air information, it is determined that the comparison result meets the ventilation condition. For example, if half of the air quality parameters are worse than the parameters in the target air information, it may be determined that the ventilation condition is satisfied. The ventilation condition may be determined according to the actual application requirement, and is not limited herein.

If the air quality in the room is good, the comparison result is not in accordance with the ventilation condition, and the air supply device does not need to be started.

In one embodiment, the target air information includes air quality parameters outside the room, the air quality parameters including: at least one of a temperature value, a humidity value, an air flow value, a carbon dioxide concentration, and a fine particulate matter concentration.

Wherein, the door and window in room is in the open mode, when air supply arrangement carried out circulation convection to the air in the room, can make the air in the room also take place the convection current with outside air, if outside air quality is lower, can reduce the air quality in the room on the contrary. Therefore, the air quality parameters in the room and the air quality parameters outside the room can be compared to judge whether the air in the room needs to be subjected to circulating convection when the door and the window are opened.

The temperature value, the humidity value, the air flow value, the carbon dioxide concentration and the fine particulate matter concentration in the air quality parameter in the room are compared with the temperature value, the humidity value, the air flow value, the carbon dioxide concentration and the fine particulate matter concentration in the air quality parameter outside the room one by one to determine a comparison result. For example, if the concentration of fine particulate matter outside a room is less than the concentration of fine particulate matter inside the room, the air supply device inside the room may be activated to supply air inside the room.

In one embodiment, as shown in FIG. 3, the method further comprises the operations of:

s201, detecting a plurality of air quality parameters of a plurality of areas in a room through an air detection device;

s202, adjusting operation parameters of the air supply device according to a plurality of air quality parameters of a plurality of areas in the room, wherein the operation parameters comprise at least one of air supply direction, air supply speed and air supply time.

Wherein, the mass of different substances in the air is different, some substances sink and some substances float in the air; thus, in the case of a relatively large space in a room, the air quality may vary in different areas of the room. Therefore, the air quality in the whole room can be judged by detecting a plurality of air quality parameters of a plurality of areas in the room, the areas can be uniformly distributed in the room, illustratively, the areas comprise an upper space and a lower space in the room, the upper space can be divided into a plurality of areas, the lower space can also be divided into a plurality of areas, a plurality of air quality parameters of the areas are respectively collected, the integral air quality in the room can be determined according to the air quality parameters, and therefore, the operation parameters of the air supply device can be adjusted according to the air quality parameters.

For example, if any two of the air quality parameters in the plurality of zones have a large difference, that is, if the air quality in at least one zone is poor, the air speed of the air supply device can be increased, and the air quality in the room can be optimized as quickly as possible. If the difference between the quality of a plurality of air parameters in a plurality of areas is gradually reduced, the air supply time of the air supply device can be timed to be a first time period, and after the air supply operation is continued for the first time period, the air supply device is closed.

In one embodiment, as shown in fig. 4, the adjusting of the operation parameters of the air supply device according to the air quality parameters of the zones in the room may be implemented by:

s2021, determining the average air quality according to a plurality of air quality parameters of the plurality of areas, and determining a target area in the plurality of areas, wherein the air quality parameter is inferior to the average air quality;

and S2022, adjusting the air supply direction of the air supply device so that the air supply device supplies air to the target area.

The average air quality is an average air quality representing air in the room, and may be determined by calculating an average of a plurality of air quality parameters of a plurality of zones.

If there is local poor air quality in the air in the room, there will be at least one zone in the plurality of zones with an air quality parameter that is worse than the average quality of the air. The determination of good or poor between the air quality parameters may be made in accordance with an air quality judgment rule, and illustratively, if the fine particulate matter concentration is high, this air quality parameter is poor.

After the average air quality is determined, areas of poor air quality parameters in the plurality of areas may be determined and identified as target areas. The air quality in the target area is poorer than that in other areas, so the air supply direction of the air supply device can be adjusted to enable the air supply device to supply air to the target area, and the circulating air flow of the air supply device can approach the target area to improve the air quality of the target area.

In one embodiment, the adjusting of the operation parameters of the air supply device according to the air quality parameters of the zones in the room may be implemented by:

determining air quality levels in the room according to a plurality of air quality parameters of the plurality of areas, and adjusting the air supply speed of the air supply device according to the air quality levels, wherein the air supply speed is lower when the air quality levels are higher, and the air supply speed is higher when the air quality levels are lower.

Wherein, after the air in the room is blown by the blowing device, the air quality in the room is gradually improved. A plurality of air quality parameters of a plurality of zones within the room may thus be continuously detected by the air detection arrangement and the air quality level within the room determined from the plurality of air quality parameters of the plurality of zones. If the air quality level in the room is low, the air in the room is not improved, and the air supply speed of the air supply device can be increased so as to enhance the air circulation strength in the room. If the air quality level in the room is higher, the air quality in the room is improved, so that the air supply speed of the air supply device can be gradually reduced, and excessive power consumption caused by continuously starting the air supply device is avoided.

In one embodiment, as shown in FIG. 5, the method further comprises the operations of:

s301, determining a wall distance between the air supply device and a target wall, wherein the target wall comprises a wall positioned on one side of the air supply direction of the air supply device;

s302, if the wall distance is larger than a first distance, controlling the air supply speed of the air supply device to be larger than a first air speed;

and S303, if the distance between the walls is smaller than a second distance, controlling the air supply speed of the air supply device to be smaller than a second air speed, wherein the second distance is smaller than or equal to the first distance, and the second air speed is smaller than or equal to the first air speed.

The air supply device is a device for generating wind power to accelerate air flow in a room, the air supply device can transmit the wind to a longer distance, and if the space in the room where the air supply device is located is smaller, the wind output by the air supply device can directly hit the wall in the room, so that better circulating airflow cannot be formed, and excessive power consumption is caused. On the other hand, if the space in the room is large, if the wind speed of the air blowing device is low, a good circulation airflow may not be formed in the room. Therefore, it is necessary to adjust the air blowing speed of the air blowing device according to the distance between the air blowing device and the wall on the side of the air blowing direction so that the air output from the air blowing device can form an effective circulating air flow in the room.

The wall distance may be determined by providing distance detection means on the air blowing device to detect a distance between a wall in front of the air blowing device and the air blowing device by the distance detection means. Wherein, the distance detection device can be a laser detection device, a depth lens or a sound wave detection sensor.

If the wall distance is greater than the first distance, the distance between the air supply device and the wall is relatively long, and the space of a room where the air supply device is located is relatively large, so that the air supply speed of the air supply device can be increased, and the air supply device can form better circulating airflow in the room. If the wall distance is less than the second distance, the distance between the air supply device and the wall is relatively short, and the room space is possibly smaller, so that the air supply speed of the air supply device can be reduced, and the air supply device can form circulating airflow in the room at a proper air speed.

The first distance and the second distance can be specifically set according to actual application requirements, and can also be determined according to actual sizes in rooms, the larger the room is, the larger the first distance and the second distance can be set relatively, and the smaller the room is, the smaller the first distance and the second distance can be set relatively. The actual dimensions of the room may be pre-stored by the user.
