Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a method for controlling air supply is provided, as shown in fig. 1, which is a flow chart of an embodiment of the method of the present invention. The air supply control method can be applied to an air conditioner with a constant air supply function, and under the condition that the constant air supply function of the air conditioner with the constant air supply function is started, the air supply control method of the air conditioner with the constant air supply function can comprise the following steps: step S110 to step S150.
In step S110, a human body location area where the user is located in the space where the air conditioner belongs is determined. A body location area, which may include: an angle region and/or a distance region.
Optionally, with reference to a flowchart of an embodiment of determining the human body location area of the user in the space to which the air conditioner belongs in the method of the present invention shown in fig. 2, a specific process of determining the human body location area of the user in the space to which the air conditioner belongs in step S110 may further be described, where the specific process includes: step S210 and step S220.
Step S210, a position of the user in the space where the air conditioner belongs is obtained.
Step S220, determining the position of the user in the space to which the air conditioner belongs and the angle area in the range of the current wind sweeping angle area of the air outlet of the air conditioner in the current space to which the air conditioner is located based on the position of the user in the space to which the air conditioner belongs; and/or determining the position of a user in the space where the air conditioner belongs, and determining the distance area in the distance area range between the air outlet of the air conditioner and the wall surface in the current space where the air conditioner is located; the air conditioner comprises a wall surface, an air outlet, a human body position area, a wind sweeping angle area range and a distance area range, wherein the air outlet is arranged on the wall surface, the wind sweeping angle area range is arranged on the air outlet, the distance area is arranged on the air conditioner, and the human body position area is located on the air conditioner.
The angle area may include: the position of the user is in an angle area within a current wind sweeping angle area range of the air outlet of the air conditioner in the current space where the air conditioner is located, namely, the position of the user is in the angle area within the current wind sweeping angle area range of the air outlet of the air conditioner in the current space. A location area, which may include: the human body position of the user is the distance area in the distance area range between the air outlet of the air conditioner and the wall surface in the current space where the air conditioner is located, namely, the human body position of the user is the distance area in the distance area range between the air outlet of the air conditioner and the wall surface in the current space.
For example: the maximum angle actually detectable by the radar, sensor, etc. detection unit may be set at each of angles, e.g., 20 °, from left to right (e.g., from the first direction a → the second direction b) according to the position of the radar, sensor, etc. detection unit, in order of θiThe maximum distance of detection means such as radar and sensor from the wall surface is divided equally by a set distance of, for example, 0.5m, and each set section from near to far, for example, each meter, is sequentially divided by SiTo show that the room is divided into a plurality of zones, each zone being denoted by thetaiSi。
Therefore, the human body position area where the user is located in the space where the air conditioner belongs is determined based on the angle area where the position where the user is located in the current wind sweeping angle area range of the air outlet of the air conditioner in the space where the air conditioner belongs and/or the distance area where the position where the user is located in the distance area range between the air outlet of the air conditioner and the wall surface, so that accurate information of the human body position area where the user is located in the space where the air conditioner belongs can be obtained, and the air supply mode of the air conditioner is controlled based on the accurate information to accurately improve the comfort experience of the user.
At step S120, according to the determined human body position region, a wind sweeping angle of the air conditioner is determined. The wind sweeping angle of the air conditioner can comprise the following steps: the left and right wind sweeping angles of the air conditioner and/or the up and down wind sweeping angles of the air conditioner.
Optionally, the determining the wind sweeping angle of the air conditioner according to the determined human body position region in step S120 may include: the first determination process for determining the left-right wind sweeping angle of the air conditioner and/or the second determination process for determining the up-down wind sweeping angle of the air conditioner can be specifically referred to the following exemplary description in any determination situation.
The first determination case: the first determining process for determining the left and right wind sweeping angles of the air conditioner may specifically include: according to a first setting relation between the set angle area and the set left and right wind sweeping angles, the set left and right wind sweeping angles corresponding to the set angle area which is the same as the angle area in the human body position area in the first setting relation are determined as the left and right wind sweeping angles corresponding to the angle area in the human body position area, so that the left and right wind sweeping angles of the air conditioner can only blow to the determined human body position area.
For example, the left and right wind sweeping angles may be set for each angle region and may be represented as αij. Such as: setting the default gear as three, when the person is in theta1In the region, the left and right wind sweeping angles can be adjusted to blow to theta only1The area can record that the left and right wind sweeping angles at this time are α13。
For example: in the process of determining the position of the human body area, if detection units such as a radar and a sensor detect and judge that the angle between the human body and the leftmost boundary a is thetai，0≤θiIf < 20, i is 1.
Second determination case: the second determining process for determining the upper and lower wind sweeping angles of the air conditioner may specifically include: and according to a second set relationship between the set distance area and the set upper and lower wind sweeping angles, determining the set upper and lower wind sweeping angles corresponding to the set distance area which is the same as the distance area in the human body position area in the second set relationship as the upper and lower wind sweeping angles corresponding to the distance area in the human body position area, so that the upper and lower wind sweeping angles of the air conditioner can only blow to the determined human body position area.
For example, the up-down wind sweeping angle can be set according to each distance area and can be represented as βij. Such as: setting default gear as three gears when the person is at S1In the region, the upper and lower wind sweeping angles can be adjusted to blow to S1The area can record the upper and lower wind sweeping angles at this time as β13。
For example: in the process of determining the position of the human body region, if detecting units such as a radar and a sensor detect and judge that the distance from the near to the far of the human body is Si，1≤SiIf < 1.5, i is 3.
In the process of determining the position of the human body area, if detection units such as a radar and a sensor detect and judge that the angle between the human body and the leftmost boundary a is thetai，0≤θiIf < 20, i is 1. If the detection means such as radar and sensor detects and determines that the distance from the near side to the far side of the human body is Si，1≤SiIf < 1.5, i is 3. Then the area where the person is located can be determined as theta1S3I.e. determining the position of the body region as theta1S3。
Therefore, the air sweeping angle of the air conditioner is determined based on the determined human body position area, so that the air conditioner can only supply air to the human body position area, the improvement of the comfort of air supply at the human body position is facilitated, and the energy conservation is facilitated by only supplying air to the human body position.
And controlling the air conditioner to sweep wind at the determined wind sweeping angle at step S130.
In the case of controlling the air conditioner to sweep wind at the determined sweep angle, a wind speed compensation value of a fan of the air conditioner is determined at step S140.
Optionally, with reference to a schematic flow chart of an embodiment of determining a wind speed compensation value of a fan of an air conditioner in the method of the present invention shown in fig. 3, a specific process of determining the wind speed compensation value of the fan of the air conditioner in step S140 is further described, which may include: step S310 to step S330.
In step S310, a first wind speed of a fan of an air conditioner under a default wind gear is determined. Wherein the first wind speed, such as the wind speed R of each default gearj. And the number of the first and second groups,
for example: the user starts the constant air function of the air conditioner and the human body induction function is started by default. Through the human body induction function, when no human activity in the room is detected, the air conditioner runs according to the wind sweeping angle and the wind speed set by the remote controller. Through the human body induction function, when the activity of a person in a room is detected, the position of a human body region can be determined, and then the wind sweeping angle and the rotating speed of the fan are determined according to the determined position of the human body region.
Step S320, determining, based on the determined wind sweeping angle of the air conditioner, that the fan of the air conditioner is at the second wind speed at the human body position region at the wind sweeping angle under the default wind shift, that is, determining the second wind speed at the determined human body position region at the default wind shift of the fan of the air conditioner at the determined wind sweeping angle. Wherein the second wind speed can be at each default wind gear, and the wind speed of the region is represented as RjSi。
And step S330, determining the difference value of the first wind speed and the second wind speed as a wind speed compensation value of a fan of the air conditioner at the position area of the human body under a default wind gear.
For example: according to experimental tests, default wind gears are set firstly, and the wind speed R of each default wind gear is determinedjJ is 1,2,3, …, which represents the number of wind stages, and may be in m/s. Meanwhile, recording the wind speed of the determined human body position area under each default wind gear as RjSiThen S is1Region, default three wind gears, wind speed R3S1The wind speed compensation value of the determined human body position area under each default wind gear is △ij＝Rj-RjSiAnd setting the rotating speed lambda of the fan.
Therefore, the wind speed compensation value of the fan of the air conditioner is determined based on the determined wind sweeping angle of the air conditioner, so that the air conditioner can further select whether wind speed compensation needs to be carried out according to the appropriate wind speed compensation value under the condition that the air conditioner only supplies air to the human body position area, constant-speed air supply to the human body position is more accurately carried out, and the user comfort experience of the human body position is more accurately improved.
In step S150, the air supply speed of the fan is controlled according to the determined wind speed compensation value of the fan.
For example: an air conditioner capable of performing intelligent air supply control can perform intelligent air supply control by actually measuring the position of a human body through a radar, a distance sensor and the like, can realize that the air conditioner adjusts the air supply mode according to regions, realizes the intelligent control of the air speed of the air conditioner, and improves the air supply comfort; the method can also realize the homoesthetic wind experience in different areas, and further increase the comfort experience of the user. Therefore, the human body can feel the same temperature, the same wind speed and the like in the air conditioning action area, and the air supply comfort of the air conditioner is improved.
Therefore, the wind sweeping angle of the air conditioner is determined based on the human body position area, the wind speed compensation value of the fan of the air conditioner is determined under the determined wind sweeping angle of the air conditioner, the air supply speed of the fan is controlled according to the determined wind speed compensation value of the fan, a human body can feel the same temperature, the same wind speed and the like in the air conditioning action area, and the comfort experience of a user is greatly improved.

Meanwhile, recording the wind speed of the determined human body position area under each default wind gear as RjSiThen S is1Region, default three wind gears, wind speed R3S1The wind speed compensation value of the determined human body position area under each default wind gear is △ij＝Rj-RjSiThe wind speed compensation value △ is obtained because the speed is not sensitive to the human bodyijThe rotating speed compensation value under each wind speed compensation value area can be determined to be △ lambda according to the set wind speed, for example, according to the division of 0.5m/siAll too | △ijWhen the | is less than 0.5m/s, the rotating speed of the fan runs according to the rotating speed of a default wind gear.
And step S420, if the absolute value of the wind speed compensation value of the fan is smaller than the set speed, controlling the air supply speed of the fan to keep the default speed to continue running.
And step S430, if the absolute value of the wind speed compensation value of the fan is greater than or equal to the set rate, determining the rotating speed compensation value of the fan corresponding to the wind speed compensation value of the fan.
