The embodiment of the application provides an air supply and ventilation method, an air supply device, an air supply system and a storage medium. 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 and ventilation method applied to an air supply device according to an embodiment of the present application, and as shown in fig. 1, the air supply and ventilation method specifically includes steps S101 to S103.

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

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.

S102, determining the distance between a door and a window in an opening state and an air supply device, wherein the air supply device is located 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, the wind is blown out spirally along a certain direction, and spiral columnar wind can be formed, so that the wind of the circulating fan can be transmitted to a longer distance, and when the circulating fan is used for supplying the wind in the room, the air in the room can form convection circulation to enhance the air flow in the room.

Under the condition that the flow value of the outside air is high, the outside air flows to the indoor through the door and the window. However, if the outside air flow value is low, the outside air does not flow into the room, so that the air flow is generated in the room by the air supply device to enhance the convection between the air in the room and the outside air.

The space in the room is generally limited, and the air supply device needs to supply air in a proper position and a proper direction so as to effectively form air circulation airflow in the room. Especially, the air in the room is communicated with the outside air through the door and window, and the air supply device needs to connect the circulating airflow path with the door and window so as to effectively enhance the flow of the air in the room and the outside air.

The distance between the door and window in the open state and the air supply device can affect the effect of the air supply device, for example, if the air supply device is close to the door and window in the open state, and if the air supply device supplies air towards the door and window, the air flow generated by the air supply device can directly flow to the outside, and the air in the room area behind the air supply device cannot be subjected to effective circulation convection. If the air supply device is far away from the door and window in the opening state and the air supply device supplies air to the door and window in a back mode, air in the space between the air supply device and the door and window in the opening state cannot be subjected to effective circulation convection. Therefore, the door and window distance between the door and window in the opening state and the air supply device can be determined, and the position of the air supply device can be determined according to the door and window distance so as to further determine the air supply direction suitable for the air supply device.

S103, controlling the air supply direction of the air supply device according to the door and window distance and the position of the door and window in the open state.

After the door and window distance and the position of the door and window in the open state are determined, the position of the air supply device in the room can be determined according to the door and window distance and the position of the door and window in the open state, and then a proper air supply direction can be determined according to the position of the air supply device in the room, so that the air supply device can form effective air circulation convection in the room, and further the convection of the air in the room and the outside air is enhanced.

In one embodiment, the controlling of the air blowing direction of the air blowing device according to the door and window distance and the position of the door and window in the open state may be implemented by:

if the distance between the door and the window is larger than a first distance, controlling the air supply direction of the air supply device to face the position of the door and the window in the open state;

and if the distance between the door and the window is smaller than a second distance, controlling the air supply direction of the air supply device to face away from the position of the door and the window in the open state, wherein the second distance is smaller than or equal to the first distance.

If the distance between the door and the window is greater than the first distance, the distance between the air supply device and the door and the window is far, and if the distance between the door and the window is smaller than the second distance, the distance between the air supply device and the door and the window is close; the first distance and the second distance can be specifically set according to the requirements of practical application, and can also be determined according to the actual size in a room, the larger the room is, the larger the first distance and the second distance can be set, and the smaller the room is, the smaller the first distance and the second distance can be set relatively. Illustratively, the room has a size of five meters by five meters, and if the door and window distance is less than one meter, it means that the air blowing device and the door and window are spaced closer, and if the door and window distance is greater than four meters, it means that the air blowing device and the door and window are spaced farther.

As shown in fig. 2, the door and window 12 and the air supply device 11 in the room 10 are far apart from each other, and the space between the door and window 12 and the air supply device 11 includes most of the space in the room 10, so that the air supply direction of the air supply device 11 is controlled to the position of the door and window 12 in the open state, and thus the air supply device 11 can perform the circulating air supply operation on the space between the door and window 12 and the air supply device 11, and the effective circulating convection of the air in the room 10 can be realized. As shown in fig. 3, the door and window 12 and the air supply device 11 in the room 10 are closer to each other, the space between the door and window 12 and the air supply device 11 is a small space in the room 10, and the side of the air supply device 11 far away from the door and window 12 is the most space in the room 10, so that the air supply direction of the air supply device 11 can be controlled to face away from the position of the door and window 12 in the open state, and the air supply device 11 can perform air supply operation on the space on the side far away from the door and window 12, so as to perform effective circulation convection on the air in the room 10.

The air supply and ventilation method provided by the embodiment of the application can determine the position relation between the door and the window and the air supply device when the door and the window are in the open state, and further control the air supply direction of the air supply device, so that the air of the air supply device in a room forms effective circulating convection, 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. 4, before the detecting, by the door/window detecting device, the door/window in the open state in the room, the following operations are further included:

s201, detecting air quality parameters in a room through an air detection device, and comparing the air quality parameters with target air information to obtain a comparison result;

s202, if the comparison result meets the ventilation condition, starting an air supply device in the room to supply air in the room by the air supply 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.

The target air information may include an air quality parameter which qualifies as air quality, and may be an air quality parameter which includes a standard, and the standard may be that human health is not affected. 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.

If the comparison result meets the ventilation condition, the air quality in the room is unqualified, or the human health is affected, so that the air supply device needs to be started to carry out circulating convection on the air in the room so as to optimize the air quality in the room. 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. 5, the method further comprises the operations of:

s301, detecting a plurality of air quality parameters of a plurality of areas in a room through an air detection device;

s302, 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. 6, 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:

s3021, determining the average air quality according to a plurality of air quality parameters of the plurality of areas, and determining a target area with the air quality parameter being worse than the average air quality in the plurality of areas;

and S3022, 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. 7, the method further comprises the operations of:

s401, 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;

s401, if the distance between the walls is larger than a third distance, controlling the air supply speed of the air supply device to be larger than a first air speed;

s401, if the distance between the walls is smaller than a fourth distance, controlling the air supply speed of the air supply device to be smaller than a second air speed, wherein the fourth distance is smaller than or equal to the third 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 third 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 fourth 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 third distance and the fourth distance may be specifically set according to actual application requirements, and may also be determined according to actual sizes in rooms, the larger the room is, the larger the third distance and the fourth distance may be set relatively, and the smaller the room is, the smaller the third distance and the fourth distance may be set relatively. The actual dimensions of the room may be pre-stored by the user.

Referring to fig. 8, fig. 8 is a schematic block diagram of a structure of an air supply device according to an embodiment of the present disclosure. The air blowing device may be a circulation fan.

Referring to fig. 8, the air supply device 100 includes a processor 110 and a memory 120 connected by a system bus, wherein the memory 120 may include a nonvolatile storage medium and an internal memory.
