Fig. 4 is a schematic flowchart of an air conditioning dehumidification control method according to a preferred embodiment of the present invention. As shown in FIG. 4, in some embodiments of the present invention, the above step S302 may include the following sub-steps
Substep S3022: the amount of air vapor in the room in which the indoor unit 100 of the air conditioner is located is determined.
In this step, first, the first temperature and the first humidity at the indoor unit 100, which are respectively detected by the temperature sensor 200 and the humidity sensor 300 disposed at the indoor unit 100, may be acquired. The amount of air vapor in the room is then calculated based on the first temperature and the first humidity.
Specifically, calculating the amount of air water vapor in the room from the first temperature and the first humidity may be performed as follows:
first, a first air saturated water vapor pressure is calculated from a first temperature. Can be specifically according to
Calculating a first air saturated water vapor pressure; wherein t1 is the first temperature, e _ s (t1) is the first temperatureAir is saturated with water vapor pressure.
After the first air saturated water vapor pressure is obtained, the first air saturated water vapor amount is calculated according to the first temperature and the first air saturated water vapor pressure. Can be as follows

And traversing each adjusting area to obtain the humidity of all the adjusting areas.
Note that, although a (t1) calculated in step S3022 above is actually the air vapor amount at the first temperature, it is considered that the air vapor amounts at the temperature of the conditioned area and the first temperature are the same because the air is uniform.
In the above embodiment, after the air water vapor amount is obtained by using the temperature and humidity detected by the temperature sensor 200 and the humidity sensor 300 provided at the indoor unit 100, the humidity of each of the adjustment areas can be calculated according to the air water vapor amount and the temperatures of the plurality of adjustment areas in the room detected by the infrared temperature measurement device 400, which is low in device cost and convenient to arrange.
After the target area is determined, in step S306, the human body information in the target area is acquired, and the air supply mode of the indoor unit to the target area is adjusted according to the human body information. Therefore, the influence of the dehumidification process on sensitive people can be reduced as much as possible.
In some embodiments of the present invention, the human body information may include the age of the human body and the comfort of the human body, which generally refers to the thermal comfort of the human body.
For the age of a human body, a human face image can be collected through a camera 600 arranged on an indoor unit, and then the human face image is identified to obtain human face information. The face information may include a face contour, a face feature point, various geometric proportion data of the face (such as a distance between two eyes), and the like, and an estimated value of the human age may be obtained by analyzing the face information, and may be used as the human age.
In addition, for the comfort level of the human body, the real-time wearing surface temperature Ts of the human body, the real-time target area temperature Th and the real-time building inner surface temperature Tq can be used for calculating the comfort level C', C ═ hr (Ts-Tq) + hc (Ts-Th). Wherein hr and hc are constants, the hr and hc are stored in an indoor unit of the air conditioner for real-time retrieval, hr is the radiative heat transfer rate, and hc is the convective heat transfer rate.
In the case that the human body information includes the age of the human body and the comfort of the human body, the adjusting the air supply mode of the indoor unit to the target area according to the human body information in step S306 may specifically include: judging whether the human body age of the target area is within a preset age interval or not; if so, judging whether the human body comfort level is higher than a preset comfort level threshold value; and if so, controlling the indoor unit to directionally supply air to the target area. The human body comfort threshold may be a numerical value set by a person, or may be obtained by self-learning according to a comfort threshold set by a user in a past period of time, which is not particularly limited in the present invention.
In addition, when the comfort level of the human body is lower than the preset comfort level threshold value or the age of the human body is outside the preset age interval, the indoor unit 100 is controlled to sweep the air back and forth with the target area as the center.
The directional air supply for the target area is to adjust the directions of the upper and lower air deflectors and the left and right swinging blades so that the indoor unit 100 supplies air for the target area, for example, if the target area is the first adjustment area B1, the left and right swinging blades are controlled to be in the first adjustment direction, and the upper and lower air deflectors are controlled to be in the fourth adjustment direction. And if the air is swung back and forth aiming at the target area, the left and right swing blades and the upper and lower air deflectors can be controlled to rotate back and forth by taking the target area as the center, so that the air is not always blown to the human body, and the influence on sensitive people can be reduced.
Wherein the preset age interval can be 18-55 years, and the human body with the age in the age interval is generally young and strong. The invention controls the indoor unit 100 to directionally supply air to the target area so as to accelerate the reduction speed of the room humidity under the condition that the target area has young and young years and the human body comfort level is higher than the preset comfort level threshold value. And under the condition that sensitive people such as old people, children and young and old people with the comfort level lower than the preset comfort level threshold exist in the target area, the indoor unit 100 is controlled to sweep air back and forth by taking the target area as the center. Therefore, the influence of the dehumidification process on sensitive people can be reduced as much as possible while the room humidity is reduced, and the intelligent level of the intelligent air conditioner is improved.
Further, after step S306, the present invention outputs a humidity display interface on the control terminal of the air conditioner, wherein the humidity display interface is used for displaying the position and the humidity of the target area. The control terminal may be a display screen of the indoor unit 100, or may be a terminal device like a mobile phone, a computer, or the like.
The humidity display interface is output on the control terminal of the air conditioner, so that a user can be reminded, and the influence on the body health of the user due to the fact that the human body is located in a high-humidity area for too long time is avoided. In addition, the user can know the humidity change condition of the target area.
Furthermore, after the humidity display interface is output on the control terminal of the air conditioner and the humidity value of the target area is reduced to be below the preset humidity threshold value, a reminding message can be output on the control terminal to remind the user that the activity range can be enlarged, and the user experience is improved.
In order that the above-described aspects of the invention may be more clearly and clearly understood. The above method proposed by the present invention is fully and specifically explained below with reference to fig. 5, and specifically includes the following steps:
step S502: the humidity of each of a plurality of adjustment areas previously divided in a room in which an indoor unit 100 of an air conditioner is located is acquired, and the adjustment area having a humidity greater than a preset humidity threshold is set as a target area.
Step S504: and acquiring human body information of the target area, wherein the human body information comprises human body age and human body comfort level.
Step S506: judging whether the age of the human body is within a preset age interval or not; if yes, go to step S510; if not, go to step S508.
Step S508: the indoor unit 100 is controlled to sweep the air around the target area.
Step S510: judging whether the comfort level of the human body is higher than a preset comfort level threshold value or not; if yes, go to step S512; if not, go to step S508.
Step S512: and controlling the indoor unit 100 to directionally supply air to the target area.
In the solution provided by the present invention, the humidity of each of a plurality of adjustment areas previously divided in a room in which an indoor unit 100 of an air conditioner is located is first acquired, and the adjustment area having a humidity greater than a preset humidity threshold is set as a target area. And then acquiring the human body information in the target area, and adjusting the air supply mode of the indoor unit 100 to the target area according to the human body information. Therefore, the influence of the dehumidification process on sensitive people can be reduced as much as possible while the room humidity is reduced. Compare in the prior art in fields such as intelligent home (wisdom family), intelligent house (intelligent house), intelligent household electrical appliances (wisdom household electrical appliances), intelligent air conditioner (wisdom air conditioner) of intelligent household electrical appliances technique.

Therefore, the user can be reminded to reduce the time length of the human body in the high-humidity area as much as possible.
Furthermore, after the humidity display interface is output on the control terminal of the air conditioner, and the humidity value of the target area is reduced to be below the preset humidity threshold value, the control terminal outputs a reminding message to remind the user that the activity range can be expanded, and the user experience is improved.
