Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a refrigeration control method of an air conditioner and a heating control method of the air conditioner, which are applied to the air conditioner.
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a refrigeration control method of an air conditioner according to an embodiment of the present invention. In this embodiment, the refrigeration control method of the air conditioner includes the steps of:
and S110, acquiring the position information of the target human body relative to the indoor unit of the air conditioner and the temperature of the target human body when the air conditioner is used for cooling.
The target human body is in the same space with the indoor unit of the air conditioner, that is, the target human body is a human body using the air conditioner, the position information of the target human body relative to the indoor unit of the air conditioner can be detected by the somatosensory radar, the temperature of the target human body is the surface temperature of the target human body, and can be detected by the infrared body temperature detection device.
And S120, adjusting the angle of the wind sweeping blade and the refrigeration parameter of the indoor unit according to the position information and the temperature.
As shown in fig. 2, fig. 2 is a sectional view of the indoor unit, in which the indoor unit is provided with the air sweeping blades 10, the air sweeping blades 10 can sweep left and right, and cold air or hot air generated in the indoor unit is blown out through gaps between the air sweeping blades 10, and the air blowing angle of the indoor unit can be changed by changing the angles of the air sweeping blades, thereby controlling the directions of the cold air or hot air generated by the air conditioner.
The position information includes a first angle, the first angle is an included angle between a connection line of a target human body and a preset point of the indoor unit and a preset straight line, the preset point may be a central point in the indoor unit, and the preset straight line is a connection line of the human body facing the indoor unit and the indoor unit, as shown in fig. 3, a point a in fig. 3 is the target human body, and α is the first angle. Adjusting the angle of the wind sweeping blade of the indoor unit according to the position information and the temperature comprises:
and S120, adjusting the angle of the wind sweeping blade of the indoor unit according to the temperature and the first angle 120 a. The method specifically comprises the following steps:
s121a, when the temperature is higher than a first preset temperature threshold value, adjusting the angle of a wind sweeping blade of the indoor unit according to the first angle so that the air supply of the indoor unit faces a target human body; or,
and S122a, when the temperature is lower than the first preset temperature threshold value, adjusting the angle of the wind sweeping blade of the indoor unit according to the first angle so as to enable the air supply of the indoor unit not to face the target human body.
In this embodiment, the sweep blade angle is an angle between the sweep blade and the original position of the sweep blade, and the original position of the sweep blade is a position perpendicular to the outer surface of the indoor unit (for example, the position of the sweep blade 10 in fig. 2).
When the temperature is higher than a first preset temperature threshold value, the surface temperature of a target human body is higher, then, the angle of the air sweeping blade of the indoor unit is adjusted according to the first angle, the air supply of the indoor unit faces the target human body, and therefore the target human body can blow cold air, and the effect of rapid cooling is achieved. When the temperature is lower than a first preset temperature threshold value, the surface temperature of a target human body is lower, the cold air demand of the target human body is lower, and then the angle of the air sweeping blade of the indoor unit is adjusted according to the first angle, so that the air supply of the indoor unit does not face the target human body, the non-wind effect is achieved, and the discomfort caused by the cold air to the target human body is prevented.
The first preset temperature threshold may be determined according to actual tests, for example, the first preset temperature threshold may be 25 degrees, 28 degrees, and the like. In order to reduce the control complexity, the angle of the wind sweeping blade is adjusted according to the first angle, so that the air supply of the indoor unit faces a target human body or does not face the target human body by setting different angle intervals, and the first angle and the wind sweeping blade angle are realized in the same angle interval or not in the same angle interval. In a possible implementation manner, the correspondence between the temperature, the first angle and the angle of the wind-sweeping blade may be as shown in table 1 (the first preset temperature threshold in table 1 is 28 degrees):
TABLE 1
It is understood that the first preset temperature threshold and the interval settings of the first angle and the sweep blade angle in table 1 may be set to other values, and the present invention is not limited to the values in table 1.
In one possible implementation manner, the refrigeration parameter includes a rotation speed of the inner fan, the position information includes a distance between a target human body and the indoor unit, and the adjusting the refrigeration parameter of the indoor unit according to the position information and the temperature includes:
and S120, 120b, adjusting the rotation speed of the inner fan according to the temperature and the distance. The method specifically comprises the following steps:
s121b, when the temperature is lower than a second preset temperature threshold value, adjusting the rotating speed of the inner fan to a first preset rotating speed; or,
s122b, when the temperature is higher than a second preset temperature threshold and the distance is smaller than a first preset distance threshold, adjusting the rotating speed of the inner fan to a second preset rotating speed; or,
and S123b, when the temperature is higher than the second preset temperature threshold and the distance is larger than the first preset distance threshold, adjusting the rotating speed of the inner fan to a third preset rotating speed.
As shown in fig. 3, the distance between the target human body (point a in the figure) and the indoor unit is a distance (S in the figure is a distance) projected from the target human body to the surface of the indoor unit on a connecting line between the target human body and the central point of the indoor unit. The rotating speed of the inner fan is used for controlling the air supply speed of the indoor unit, the faster the rotating speed of the inner fan is, the larger the air speed sent out by the indoor unit is, the slower the rotating speed of the inner fan is, and the smaller the air speed sent out by the indoor unit is.
The first preset rotating speed is not more than the second preset rotating speed, and the second preset rotating speed is not more than the third preset rotating speed.
When the temperature is lower than the second preset temperature threshold value, the surface temperature of the target human body is lower, the requirement of the target human body for the wind speed is lower at the moment, and therefore the rotating speed of the inner fan is adjusted to be lower than the first preset rotating speed at the moment. When the temperature is higher than the second preset temperature threshold, the surface temperature of the target human body is higher, and if the distance is smaller than the first preset distance threshold, that is, the target human body is closer to the indoor unit, and therefore, the requirement of the target human body for the wind speed is lower than that when the distance is greater than the first preset distance threshold value because the target human body is closer to the cold source, and therefore, when the temperature is higher than a second preset temperature threshold and the distance is smaller than a first preset distance threshold, the rotating speed of the inner fan is adjusted to a second preset rotating speed, when the temperature is higher than a second preset temperature threshold and the distance is larger than a first preset distance threshold, the rotating speed of the inner fan is adjusted to a third preset rotating speed, the second preset rotating speed is not less than the first preset rotating speed, and the second preset rotating speed is not more than the third preset rotating speed, so that the user can quickly cool down when the body temperature is high, meanwhile, the effect of reducing the energy consumption of the air conditioner and avoiding the uncomfortable feeling caused by the strong wind blowing to the human body in a short distance can be achieved.
The first preset rotation speed, the second preset rotation speed and the third preset rotation speed may be a single value or a range of values, for example, the first preset rotation speed may be (800, 900), the second preset rotation speed may be (900, 1000), the third preset rotation speed may be (1000, 1100), and the like. The second preset temperature threshold may be provided in plurality, for example, the second preset temperature threshold may be 25 degrees, 30 degrees, and the like, and the first preset distance threshold may also be provided in plurality, for example, the first preset distance threshold may be 3 meters, 2 meters, and the like. The first preset rotating speed, the second preset rotating speed and the third preset rotating speed corresponding to different second preset temperature thresholds and first preset distance thresholds can be different. Therefore, the corresponding relation among different temperature intervals, distance intervals and the rotating speed of the inner fan can be formed. In one possible implementation, the table for controlling the rotation speed of the internal fan is shown in table 2 (in table 2, the second preset temperature thresholds are 28 degrees and 33 degrees, and the first preset distance thresholds are 4 meters and 7 meters):
TABLE 2
It is understood that the second preset temperature threshold and the second preset distance threshold and the setting of the internal fan speed in table 2 may be set to other values, and the present invention is not limited to the values in table 2.
In one possible implementation, the refrigeration parameter includes a compressor operating frequency, and adjusting the refrigeration parameter of the indoor unit according to the position information and the temperature includes:
and S120, 120c, adjusting the running frequency of the compressor of the indoor unit according to the temperature and the distance. The method specifically comprises the following steps:
s121c, when the temperature is lower than a third preset temperature threshold value, adjusting the running frequency of the compressor to a first preset frequency;
s122c, when the temperature is higher than a third preset temperature threshold value, adjusting the running frequency of the compressor to a second preset frequency;
wherein, the first preset frequency is not more than the second preset frequency.
The running frequency of the compressor can influence the output power of the air conditioner, and during refrigeration, the larger the running frequency of the compressor is, the larger the refrigerating capacity of the air conditioner is, the lower the temperature of cold air sent by the indoor unit is, the smaller the running frequency of the compressor is, the smaller the refrigerating capacity of the air conditioner is, and the higher the temperature of the cold air sent by the indoor unit is. When the temperature is lower than the third preset temperature threshold, the corresponding compressor operation frequency is not greater than the compressor operation frequency when the temperature is higher than the third preset temperature threshold, therefore, when the temperature is lower than the third preset temperature threshold, the compressor operation frequency is adjusted to the first preset frequency, when the temperature is higher than the third preset temperature threshold, the compressor operation frequency is adjusted to the second preset frequency, and the first preset frequency is not greater than the second preset frequency. Therefore, the effects of quickly cooling the user when the body temperature is high and reducing the energy consumption of the air conditioner can be achieved.
Because the target human body is relatively close to the indoor unit and relatively close to the cold source, the influence of air-conditioning refrigeration on the target human body is relatively large, and the air-conditioning refrigeration quantity required by the target human body is not higher than the air-conditioning refrigeration quantity required by the target human body when the target human body is relatively far from the indoor unit, in a possible implementation manner, when the temperature is higher than a third preset temperature threshold value, the running frequency of the compressor is also adjusted according to the distance between the target human body and the indoor unit, specifically, the third preset distance threshold value can be set, and when the distance is smaller than the third preset distance threshold value, the corresponding running frequency of the compressor is smaller than the running frequency of the compressor when the distance is larger than the third preset distance threshold value, so that the effects that the user can quickly cool and reduce the energy consumption of the air conditioner even when the user is relatively far from the air conditioner when the.
The first preset frequency and the second preset frequency may be a single value or a range of values, for example, the first preset frequency may be (30.44), (44.58), etc. The third preset temperature threshold may be equal to or not equal to the second preset temperature threshold, and the third preset temperature threshold may be provided in multiple numbers, for example, 18 degrees, 25 degrees, and the like, and in a possible implementation, the control table of the compressor operation frequency is as shown in table 3 (the third preset temperature threshold in table three is 28 degrees and 32 degrees):
TABLE 3
It is understood that the third preset temperature threshold and the compressor operating frequency in table 3 may be set to other values, and the present invention is not limited to the values in table 3.
It should be noted that in the refrigeration control method of the air conditioner provided by the present invention, S120a, adjusting the angle of the wind-sweeping blade of the indoor unit according to the temperature and the first angle, S120b, adjusting the rotation speed of the internal fan of the indoor unit according to the temperature and the distance, and S120c, adjusting the operation frequency of the compressor of the indoor unit according to the temperature and the distance may be implemented individually, or implemented by combining two or three of them together.
Example two
The present invention also provides a heating control method of an air conditioner, as shown in fig. 4, an embodiment of the method includes the steps of:
s210, when the air conditioner heats, acquiring position information of the target human body relative to an indoor unit of the air conditioner and the temperature of the target human body.

And S220, adjusting the angle of a wind sweeping blade and heating parameters of the indoor unit according to the position information and the temperature.
As shown in fig. 2, fig. 2 is a sectional view of the indoor unit, in which the indoor unit is provided with the air sweeping blades 10, the air sweeping blades 10 can sweep left and right, and cold air or hot air generated in the indoor unit is blown out through gaps between the air sweeping blades 10, and the air blowing angle of the indoor unit can be changed by changing the angles of the air sweeping blades, thereby controlling the directions of the cold air or hot air generated by the air conditioner.
The position information includes a first angle, where the first angle is an included angle between a connection line between a target human body and a preset point of the indoor unit and a preset straight line, the preset point may be a central point in the indoor unit, and the preset straight line is a connection line between the human body facing the indoor unit and the indoor unit, as shown in fig. 3, α in fig. 3 is the first angle, and of course, it can be understood by those skilled in the art that different preset points and preset straight lines may be set to determine the first angle. Adjusting the angle of the wind sweeping blade of the indoor unit according to the position information and the temperature comprises:
and S220a, adjusting the angle of the wind sweeping blade of the indoor unit according to the temperature and the first angle. The method specifically comprises the following steps:
s221a, when the temperature is lower than a fourth preset temperature threshold value, adjusting the angle of a wind sweeping blade of the indoor unit according to the first angle so that the air supply of the indoor unit faces a target human body; or,
and S222a, when the temperature is higher than a fourth preset temperature threshold value, adjusting the angle of the wind sweeping blade of the indoor unit according to the first angle so that the air supply of the indoor unit does not face the target human body.
In this embodiment, the sweep blade angle is an angle between the sweep blade and the original position of the sweep blade, and the original position of the sweep blade is a position perpendicular to the outer surface of the indoor unit (for example, the position of the sweep blade 10 in fig. 2).

When the temperature is higher than the fourth preset temperature threshold value, the surface temperature of the target human body is higher, the hot air demand of the target human body is lower, and then the angle of the air sweeping blade of the indoor unit is adjusted according to the first angle, so that the air supply of the indoor unit does not face the target human body, the non-wind effect is achieved, and the discomfort caused by the hot air to the target human body is prevented.
The fourth preset temperature threshold may be determined according to actual tests, for example, the fourth preset temperature threshold may be 18 degrees, 20 degrees, and the like. In order to reduce the control complexity, the angle of the wind sweeping blade is adjusted according to the first angle, so that the air supply of the indoor unit faces a target human body or does not face the target human body by setting different angle intervals, and the first angle and the wind sweeping blade angle are realized in the same angle interval or not in the same angle interval. In a possible implementation manner, the correspondence relationship between the temperature, the first angle and the angle of the wind sweeping blade may be as shown in table 4 (the fourth preset temperature threshold in table 4 is 18 degrees):

and S220b, adjusting the rotation speed of the inner fan according to the temperature and the distance. The method specifically comprises the following steps:
s221b, when the temperature is higher than a fifth preset temperature threshold value, adjusting the rotating speed of the inner fan to a fourth preset rotating speed; or,
s222b, when the temperature is lower than a fifth preset temperature threshold and the distance is smaller than a second preset distance threshold, adjusting the rotating speed of the inner fan to a fifth preset rotating speed; or,
and S223b, when the temperature is lower than a fifth preset temperature threshold value and the distance is larger than a second preset distance threshold value, adjusting the rotating speed of the inner fan to a sixth preset rotating speed.
As shown in fig. 3, the distance between the target human body (point a in the figure) and the indoor unit is a distance (S in the figure is a distance) projected from the target human body to the surface of the indoor unit on a connecting line between the target human body and the central point of the indoor unit. The rotating speed of the inner fan is used for controlling the air supply speed of the indoor unit, the faster the rotating speed of the inner fan is, the larger the air speed sent out by the indoor unit is, the slower the rotating speed of the inner fan is, and the smaller the air speed sent out by the indoor unit is.
The fourth preset rotating speed is not greater than the fifth preset rotating speed, and the fifth preset rotating speed is not greater than the sixth preset rotating speed.
When the temperature is higher than the fifth preset temperature threshold value, the surface temperature of the target human body is higher, and the requirement of the target human body for the wind speed is lower at the moment, so that the rotating speed of the inner fan is adjusted to be lower than the fourth preset rotating speed at the moment. When the temperature is lower than a fifth preset temperature threshold value, the surface temperature of the target human body is lower, and if the distance is smaller than a second preset distance threshold value, that is, the target human body is closer to the indoor unit, and therefore, the requirement of the target human body for the wind speed is lower than that when the distance is greater than the second preset distance threshold value because the target human body is closer to the heat source, and therefore, when the temperature is lower than a fifth preset temperature threshold and the distance is less than a second preset distance threshold, the rotating speed of the inner fan is adjusted to a fifth preset rotating speed, when the temperature is lower than a fifth preset temperature threshold and the distance is greater than a second preset distance threshold, the rotating speed of the inner fan is adjusted to a sixth preset rotating speed, the fifth preset rotating speed is not less than a fourth preset rotating speed, and the fifth preset rotating speed is not greater than the sixth preset rotating speed, so that the rapid temperature rise of the user at low body temperature can be realized, meanwhile, the effect of reducing the energy consumption of the air conditioner and avoiding the uncomfortable feeling caused by the strong wind blowing to the human body in a short distance can be achieved.
The fourth preset rotation speed, the fifth preset rotation speed and the sixth preset rotation speed may be a single value or a range of values, for example, the fourth preset rotation speed may be (700, 800), the fifth preset rotation speed may be (800, 900), the sixth preset rotation speed may be (900, 1000), and the like. The fifth preset temperature threshold may be provided in plural, for example, the fifth preset temperature threshold may be 15 degrees, 20 degrees, etc., and the second preset distance threshold may also be provided in plural, for example, the second preset distance threshold may be 3 meters, 2 meters, etc. The fourth preset rotating speed, the fifth preset rotating speed and the sixth preset rotating speed corresponding to different fifth preset temperature thresholds and second preset distance thresholds can be different. Therefore, the corresponding relation among different temperature intervals, distance intervals and the rotating speed of the inner fan can be formed. In one possible implementation, the table for controlling the rotation speed of the internal fan is shown in table 5 (in table 5, the fifth preset temperature thresholds are 18 degrees and 23 degrees, and the second preset distance thresholds are 4 meters and 7 meters):
TABLE 5
It is understood that the fifth preset temperature threshold and the fourth preset distance threshold and the internal fan speed in table 5 may be set to other values, and the present invention is not limited to the values in table 5.
In one possible implementation, the heating parameter includes a compressor operating frequency, and adjusting the heating parameter of the indoor unit according to the position information and the temperature includes:
and S220c, adjusting the running frequency of the compressor of the air conditioner according to the temperature and the distance. The method specifically comprises the following steps:
s221c, when the temperature is higher than a sixth preset temperature threshold value, adjusting the running frequency of the compressor to a third preset frequency; or,
s222c, when the temperature is lower than a sixth preset temperature threshold value, adjusting the running frequency of the compressor to a fourth preset frequency;
and the third preset frequency is not more than the fourth preset frequency.
The operation frequency of the compressor influences the output power of the air conditioner, and during heating, the larger the operation frequency of the compressor is, the larger the heating capacity of the air conditioner is, the higher the temperature of hot air sent by the indoor unit is, and the smaller the operation frequency of the compressor is, the smaller the heating capacity of the air conditioner is, and the lower the temperature of hot air sent by the indoor unit is. When the temperature is higher than the sixth preset temperature threshold, the corresponding compressor operation frequency is not greater than the compressor operation frequency when the temperature is lower than the sixth preset temperature threshold, therefore, when the temperature is higher than the sixth preset temperature threshold, the compressor operation frequency is adjusted to the third preset frequency, when the temperature is lower than the sixth preset temperature threshold, the compressor operation frequency is adjusted to the fourth preset frequency, and the third preset frequency is not greater than the fourth preset frequency. Therefore, the effects of quickly cooling the user when the body temperature is high and reducing the energy consumption of the air conditioner can be achieved.
When the distance is smaller than the fourth preset distance threshold, the corresponding compressor running frequency is smaller than the compressor running frequency when the distance is larger than the fourth preset distance threshold, so that the effects that the temperature of a user can be quickly raised and the energy consumption of the air conditioner can be reduced even at a place far away from the air conditioner when the body temperature is low can be achieved.
The third preset frequency and the fourth preset frequency may be a single value or a range of values, for example, the third preset frequency may be (30.44), (44.58), etc. The sixth preset temperature threshold may be equal to or not equal to the fifth preset temperature threshold, and the sixth preset temperature threshold may be provided in multiple numbers, for example, 15 degrees, 20 degrees, and the like, and in a possible implementation, the control table of the compressor operation frequency is shown in table 6 (the sixth preset temperature threshold in table 6 is 18 degrees and 23 degrees):
TABLE 6
It is understood that the sixth preset temperature threshold and the compressor operating frequency in table 6 can be set to other values, and the present invention is not limited to the values in table 6.
It should be noted that in the heating control method of the air conditioner provided by the present invention, S220a, adjusting the angle of the wind sweeping blade of the indoor unit according to the temperature and the first angle, S220b, adjusting the rotation speed of the inner fan of the indoor unit according to the temperature and the distance, and S220c, adjusting the operation frequency of the compressor of the indoor unit according to the temperature and the distance may be implemented individually, or implemented by combining two or three of them together.
