Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of an air conditioner, a control device of an air conditioner, and an air conditioner according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention. As shown in fig. 1, the control includes the steps of:
s1: and receiving a dynamic wind opening instruction, and adjusting the air outlet speed and/or the air direction of the air conditioner according to the dynamic wind opening instruction.
That is to say, in the cooling mode, after receiving the dynamic wind start instruction, the dynamic change of the rotating speed of the wind wheel of the air conditioner and/or the dynamic swing of the wind guide mechanism of the air conditioner can be controlled, so that the wind outlet speed and/or the wind direction of the air conditioner can be dynamically changed, and the dynamic wind effect can be realized.
For example, the rotation speed of the wind guide mechanism and/or the wind wheel can be controlled according to a pre-stored natural wind speed sample, so that the position, the angle and the movement speed of the wind guide mechanism are/is continuously changed and/or the rotation speed of the wind wheel is continuously changed, and the wind outlet speed and/or the wind direction of the air conditioner are/is adjusted.
S2: it is detected whether the room temperature T1 is lower than a first preset value T1 c.
Wherein the room temperature T1 can be detected by a room temperature sensor provided at the air intake.
Specifically, the room temperature T1 is detected while the outlet wind speed and/or the wind direction of the air conditioner is adjusted according to the dynamic wind turn-on command, and it is determined whether the room temperature T1 is lower than a first preset value T1 c.
S3: if the room temperature T1 is lower than the first preset value T1c, the air outlet temperature T2 of the air conditioner or the temperature T3 of the user in the room is obtained.
S4: and controlling the working frequency of the compressor of the air conditioner according to the air outlet temperature T2 of the air conditioner or the temperature T3 of the user in the room.
Specifically, after receiving the dynamic wind turn-on command, during the operation of the air conditioner, the room temperature T1 and the first preset value T1c may be determined once every preset time threshold Δ T, for example, Δ T may be 1 minute, to determine whether the room temperature T1 is lower than the first preset value T1c, that is, whether to enter the outlet temperature control mode or the temperature-around-the-body control mode, that is, the operating frequency of the compressor of the air conditioner is controlled according to the outlet temperature T2 of the air conditioner or the temperature-around-the-body T3 of the user in the room.
If the room temperature T1 is lower than a first preset value T1c, entering an air outlet temperature control mode or a temperature around the body temperature control mode; if the room temperature T1 is higher than the first preset value T1c, the air conditioner continues to be controlled to operate in a current operation mode, for example, a normal operation mode.
The first default value T1c may be 30 degrees celsius, or the first default value T1c may be a sum of the user set value Ts and the fourth default value T4c, for example, the first default value T1c may be positively correlated with the user set value Ts, and T4c may be 4 degrees celsius. That is, if T1 is lower than Ts + T4c, enter the outlet temperature control mode or the temperature control mode around the body; if T1 is higher than Ts + T4c, the air conditioner is continuously controlled to operate in the normal operation mode. Preferably, when the sum of the user set value Ts and the fourth preset value T4c is greater than 30 degrees celsius, i.e. when Ts +4 degrees celsius > 30 degrees celsius, the first preset value T1c may be directly set to 30 degrees celsius.
In addition, in order to reduce the influence of errors and prevent frequent switching of the operation mode of the air conditioner, a temperature threshold Δ T may be preset, for example, Δ T may be 0.5 degrees celsius when the relationship between the room temperature T1 and the first preset value T1c is judged. That is, in the normal operation mode, when the room temperature T1 is lower than the first preset value T1c minus the temperature threshold Δ T, i.e., T1 is lower than T1c-0.5 ℃, the air outlet temperature control mode or the temperature around the body control mode is entered; in the air outlet temperature control mode or the temperature control mode at the side, when the room temperature T1 is higher than the first preset value T1c plus the temperature threshold Δ T, i.e., T1 is higher than T1c +0.5 ℃, the air outlet temperature control mode or the temperature control mode at the side exits and enters the normal operation mode.
It should be noted that, in the normal operation mode, the operating frequency of the compressor of the air conditioner may be controlled only according to the room temperature T1 and the user set value Ts.
According to an embodiment of the present invention, controlling the operating frequency of the air conditioner according to the outlet temperature of the air conditioner specifically includes: if the air outlet temperature T2 is greater than a second preset value T2c, the working frequency of the compressor is increased; if the air outlet temperature T2 is equal to a second preset value T2c, maintaining the working frequency of the compressor; and if the air outlet temperature T2 is less than the second preset value T2c, reducing the working frequency of the compressor. Preferably, the second preset value T2c can be set according to the user set value Ts.
The air outlet temperature T2 may be obtained by a temperature sensor disposed at the air outlet, or may be calculated by operating parameters of the air conditioner.
That is, in the outlet temperature control mode, the outlet temperature T2 is detected or the outlet temperature T2 is calculated according to the operating parameters of the air conditioner, and the outlet temperature T2 is compared with the second preset value T2c, when T2 is greater than T2c, the working frequency of the compressor is increased to improve the refrigeration capacity and reduce the outlet temperature of the air conditioner; when T2 is less than T2c, the working frequency of the compressor is reduced to reduce the refrigerating capacity and improve the temperature of an air outlet of the air conditioner; when T2 equals T2c, it indicates that the current operating parameters are satisfactory, maintaining the operating frequency of the compressor.
In addition, in order to reduce the influence of errors and prevent the frequent switching of the operation mode of the air conditioner, a certain error, for example, ± 0.5 ℃, is allowed when the relationship between the outlet temperature T2 and the second preset value T2c is judged. Specifically, a temperature threshold Δ T may be preset (for example, Δ T may be 0.5), and when the outlet temperature T2 is greater than a second preset value T2c plus the temperature threshold Δ T, that is, T2> T2c +0.5, the operating frequency of the compressor is reduced; when the air outlet temperature T2 is smaller than a value obtained by subtracting a temperature threshold value delta T from a second preset value T2c, namely T2 is less than T2c-0.5, the working frequency of the compressor is reduced; when the air outlet temperature T2 is greater than or equal to the value obtained by subtracting the temperature threshold value delta T from the second preset value T2c and is less than or equal to the value obtained by adding the temperature threshold value delta T to the second preset value T2c, namely T2c-0.5 is greater than or equal to T2 and is greater than or equal to T2c +0.5, the working frequency of the compressor is kept unchanged.
According to another embodiment of the present invention, the controlling the operating frequency of the air conditioner according to the temperature around the user specifically comprises: if the temperature T3 around is greater than the third preset value T3c, the working frequency of the compressor is increased; if the temperature T3 around is equal to the third preset value T3c, the working frequency of the compressor is maintained; if the temperature around T3 is less than the third preset value T3c, the operating frequency of the compressor is reduced. Preferably, the third preset value T3c can be set according to the user set value Ts.
The body temperature T3 may be the temperature of the position of the user in the room, and the body temperature T3 may be obtained by an infrared detection device, or may be obtained by wearable equipment worn by the user and sent to the air conditioner. That is, the temperature T3 around the person may be detected by an infrared detection device provided in the air conditioner, or the temperature T3 around the person may be detected by a wearable device worn by the user, and the detected temperature T3 around the person may be transmitted to the air conditioner.
That is, in the temperature control mode around, the temperature around T3 is detected and the temperature around T3 is compared with the third preset value T3c, and when T3 is greater than T3c, the operating frequency of the compressor is increased to increase the cooling capacity and reduce the temperature around the user; when T3 is less than T3c, the working frequency of the compressor is reduced to reduce the refrigerating capacity and increase the temperature of the user; when T3 equals T3c, it indicates that the current operating parameters are satisfactory, maintaining the operating frequency of the compressor.
In addition, in order to reduce the influence of errors and prevent frequent switching of the operation mode of the air conditioner, a certain error, for example, ± 0.5 ℃, is allowed when determining the relationship between the temperature around T3 and the third preset value T3 c. Specifically, a temperature threshold Δ T may be preset (for example, Δ T may be 0.5), and when the body temperature T3 is greater than a third preset value T3c plus the value of the temperature threshold Δ T, i.e., T3> T3c +0.5, the operating frequency of the compressor is reduced; when the temperature T3 around is less than the third preset value T3c minus the temperature threshold value delta T, namely T3 is less than T3c-0.5, the working frequency of the compressor is reduced; when the temperature T3 around the body is greater than or equal to the value obtained by subtracting the temperature threshold value delta T from the third preset value T3c and less than or equal to the value obtained by adding the temperature threshold value delta T to the third preset value T3c, namely T3c-0.5 is greater than or equal to T3 is greater than or equal to T3c +0.5, the working frequency of the compressor is kept unchanged.
In general, the control method of the embodiment of the invention can include a dynamic wind function and an outlet temperature control mode, in the refrigeration mode, after receiving a dynamic wind starting command, starting a dynamic wind function, dynamically changing the wind speed and/or the wind direction of the air conditioner, simultaneously judging whether the room temperature T1 is lower than a first preset value T1c, if T1 is lower than T1c, entering an air outlet temperature control mode, detecting the air outlet temperature T2, controlling the air conditioner air outlet temperature T2 to reach a second preset value T2c, that is, when T2 is greater than T2c, the operating frequency of the compressor is increased, when T2 is less than T2c, the operating frequency of the compressor is decreased, when T2 is equal to T2c, the operating frequency of the compressor is maintained, in the above operation process, if the room temperature T1 rises above the first preset value T1c, the outlet temperature control mode is exited, and the normal operation mode is returned.
Or, the control method of the embodiment of the present invention may further include a dynamic wind function and a body temperature control mode, in the cooling mode, after receiving a dynamic wind start instruction, the dynamic wind function is started, the wind speed and/or the wind direction of the outlet air of the air conditioner will dynamically change, and at the same time, it is determined whether the room temperature T1 is lower than a first preset value T1c, if T1 is lower than T1c, the body temperature control mode is entered, the body temperature T3 is detected, and the body temperature T3 of the air conditioner is controlled to reach a third preset value T3c, that is, when T3 is greater than T3c, the operating frequency of the compressor is increased, when T3 is less than T3c, the operating frequency of the compressor is decreased, when T3 is equal to T3c, the operating frequency of the compressor is maintained, and in the above-mentioned operation process, if the room temperature T1 is increased to be greater than a first preset value T1c, the body temperature control mode is.
Specifically, according to an embodiment of the present invention, as shown in fig. 2, a control method including a dynamic wind function and an outlet temperature control mode is taken as an example to describe in detail a control method of an air conditioner according to an embodiment of the present invention.

S106: the operating frequency of the compressor is increased and after a time threshold Δ t, the process returns to step S103.
S107: the operating frequency of the compressor is maintained, and after the time threshold Δ t, the process returns to step S103.
S108: the operating frequency of the compressor is reduced and after a time threshold Δ t, the process returns to step S103.

In summary, according to the control method of the air conditioner provided by the embodiment of the present invention, after receiving the dynamic wind turn-on instruction, the wind outlet speed and/or the wind direction of the air conditioner are/is adjusted according to the dynamic wind turn-on instruction, and meanwhile, whether the room temperature is lower than the first preset value is also detected, if the room temperature is lower than the first preset value, the air outlet temperature of the air conditioner or the temperature around the user in the room is obtained, and the operating frequency of the compressor of the air conditioner is controlled according to the air outlet temperature of the air conditioner or the temperature around the user in the room. Therefore, the method can blow dynamic wind with proper temperature to the user by controlling the wind outlet speed and/or the wind direction and the temperature of the air outlet, and meets the requirements of the user on the dynamic wind and the comfortable temperature of the air outlet, thereby improving the monotonous feeling of the air blowing of the air conditioner, enabling the air blowing of the air conditioner to be more natural, providing comfortable air blowing feeling for the user, simultaneously reducing the energy consumption of the air conditioner and saving energy.
Fig. 3 is a block diagram schematically illustrating a control apparatus of an air conditioner according to an embodiment of the present invention. As shown in fig. 3, the control apparatus of the air conditioner includes: a receiving module 1, a room temperature detecting module 2 and a control module 3.
The receiving module 1 is used for receiving a dynamic wind starting instruction input by a user; the room temperature detecting module 2 is used for detecting a room temperature T1, for example, the room temperature detecting module 2 is a room temperature sensor arranged at the air inlet; the control module 3 is respectively connected with the receiving module 1 and the room temperature detecting module 2, the control module 3 is configured to, after receiving the dynamic wind starting instruction, adjust an air outlet speed and/or an air direction of the air conditioner according to the dynamic wind starting instruction, and determine whether the room temperature T1 is lower than a first preset value T1c, if the room temperature T1 is lower than the first preset value T1c, obtain an air outlet temperature T2 of the air conditioner or a temperature T3 of a user in the room, and control a working frequency of a compressor of the air conditioner according to an air outlet temperature T2 of the air conditioner or a temperature T3 of the user in the room.
That is to say, in the cooling mode, after the receiving module 1 receives the dynamic wind start instruction, the control module 3 may control the rotational speed of the wind wheel of the air conditioner to dynamically change and/or control the wind guiding mechanism of the air conditioner to dynamically swing, so that the wind outlet speed and/or the wind direction of the air conditioner dynamically change, thereby implementing the dynamic wind effect. For example, the control module may control the rotation speed of the wind guide mechanism and/or the wind wheel according to a pre-stored natural wind speed sample, so that the position, the angle and the movement speed of the wind guide mechanism are continuously changed and/or the rotation speed of the wind wheel is continuously changed, thereby adjusting the wind outlet speed and/or the wind direction of the air conditioner.
The method comprises the steps that when the air outlet speed and/or the air direction of the air conditioner are/is adjusted according to a dynamic wind opening instruction, the room temperature T1 is detected, the room temperature detection module 2 detects the room temperature T1, the control module 3 judges whether the room temperature T1 is lower than a first preset value T1c, if the room temperature T1 is lower than a first preset value T1c, the control module 3 controls the air conditioner to enter an air outlet temperature control mode or a body temperature control mode, namely the control module 3 controls the working frequency of a compressor of the air conditioner according to the air outlet temperature T2 of the air conditioner or the body temperature T3 of a user in a room; if the room temperature T1 is higher than the first preset value T1c, the control module 3 continues to control the air conditioner to operate in a current operation mode, for example, a normal operation mode.
Specifically, after the receiving module 1 receives the dynamic wind start command, in the operation process of the air conditioner, the control module 3 may perform a judgment on the room temperature T1 and the first preset value T1c every time a preset time threshold Δ T, for example, Δ T may be 1 minute, to determine whether the room temperature T1 is lower than the first preset value T1c, that is, whether to enter the outlet temperature control mode or the temperature around the air conditioner.
The first default value T1c may be 30 degrees celsius, or the first default value T1c may be a sum of the user set value Ts and the fourth default value T4c, for example, the first default value T1c may be positively correlated with the user set value Ts, and T4c may be 4 degrees celsius. That is, if T1 is lower than Ts + T4c, the control module 3 controls the air conditioner to enter the outlet temperature control mode or the temperature-around-the-body control mode; if T1 is above Ts + T4c, the control module 3 continues to control the air conditioner to operate in the normal operation mode. Preferably, when the sum of the user set value Ts and the fourth preset value T4c is greater than 30 degrees celsius, that is, when Ts +4 degrees celsius is greater than 30 degrees celsius, the control module 3 may directly set the first preset value T1c to 30 degrees celsius.
In addition, in order to reduce the influence of errors and prevent frequent switching of the operation mode of the air conditioner, a temperature threshold Δ T may be preset, for example, Δ T may be 0.5 degrees celsius when the relationship between the room temperature T1 and the first preset value T1c is judged. That is, in the normal operation mode, when the room temperature T1 is lower than the first preset value T1c minus the temperature threshold Δ T, i.e., T1 is lower than T1c-0.5 ℃, the control module 3 controls the air conditioner to enter the outlet temperature control mode or the temperature around the body control mode; in the outlet temperature control mode or the temperature control mode around, when the room temperature T1 is higher than the first preset value T1c plus the temperature threshold Δ T, i.e., T1 is higher than T1c +0.5 ℃, the control module 3 controls the air conditioner to exit the outlet temperature control mode or the temperature control mode around, and enter the normal operation mode.
It should be noted that, in the normal operation mode, the control module 3 may control the operating frequency of the compressor of the air conditioner only according to the room temperature T1 and the user set value Ts.
According to a specific example of the present invention, the receiving module 1 may receive the dynamic wind turn-on command through a human-computer interaction interface disposed on the air conditioner, or receive the dynamic wind turn-on command through a remote controller of the air conditioner, or receive the dynamic wind turn-on command through a mobile terminal in communication with the air conditioner.
According to an embodiment of the present invention, when the control module 3 controls the operating frequency of the compressor of the air conditioner according to the outlet temperature T2 of the air conditioner, the control device 3 is specifically configured to: if the air outlet temperature T2 is greater than the second preset value T2c, the control device 3 increases the working frequency of the compressor; if the outlet temperature T2 is equal to the second preset value T2c, the control device 3 maintains the operating frequency of the compressor; if the outlet temperature T2 is less than the second preset value T2c, the control device 3 reduces the operating frequency of the compressor. Preferably, the second preset value T2c can be set according to the user set value Ts.
The air outlet temperature T2 may be obtained by a temperature sensor disposed at the air outlet, or may be calculated by operating parameters of the air conditioner.
That is, in the outlet temperature control mode, the temperature sensor detects the outlet temperature T2 or the control module 3 calculates the outlet temperature T2 according to the operating parameters of the air conditioner and compares the outlet temperature T2 with the second preset value T2c, and when T2 is greater than T2c, the control module 3 increases the operating frequency of the compressor to increase the refrigeration capacity and reduce the outlet temperature of the air conditioner; when the T2 is smaller than the T2c, the control module 3 reduces the working frequency of the compressor to reduce the refrigerating capacity and improve the temperature of an air outlet of the air conditioner; when T2 equals T2c, indicating that the current operating parameters are satisfactory, the control module 3 maintains the operating frequency of the compressor.
In addition, in order to reduce the influence of errors and prevent the frequent switching of the operation mode of the air conditioner, a certain error, for example, ± 0.5 ℃, is allowed when the relationship between the outlet temperature T2 and the second preset value T2c is judged. Specifically, a temperature threshold Δ T may be preset (for example, Δ T may be 0.5), and when the outlet temperature T2 is greater than a second preset value T2c plus the temperature threshold Δ T, that is, T2> T2c +0.5, the control module 3 reduces the operating frequency of the compressor; when the air outlet temperature T2 is smaller than a value obtained by subtracting the temperature threshold delta T from the second preset value T2c, namely T2 is less than T2c-0.5, the control module 3 reduces the working frequency of the compressor; when the air outlet temperature T2 is greater than or equal to the value obtained by subtracting the temperature threshold value Δ T from the second preset value T2c and is less than or equal to the value obtained by adding the temperature threshold value Δ T to the second preset value T2c, i.e., T2c-0.5 is greater than or equal to T2 is greater than or equal to T2c +0.5, the control module 3 keeps the operating frequency of the compressor unchanged.
According to another embodiment of the present invention, when the control module 3 controls the operating frequency of the compressor of the air conditioner according to the temperature around the user, the control device 3 is specifically configured to: if the temperature T3 around is greater than the third preset value T3c, the device 3 increases the operating frequency of the compressor; if the temperature around T3 is equal to the third preset value T3c, the device 3 maintains the operating frequency of the compressor; if the temperature around T3 is less than the third preset value T3c, the device 3 reduces the operating frequency of the compressor. Preferably, the third preset value T3c can be set according to the user set value Ts.
The body temperature T3 may be the temperature of the position of the user in the room, and the body temperature T3 may be obtained by an infrared detection device, or may be obtained by wearable equipment worn by the user and sent to the air conditioner. That is, the temperature T3 around the person may be detected by an infrared detection device provided in the air conditioner, or the temperature T3 around the person may be detected by a wearable device worn by the user, and the detected temperature T3 around the person may be transmitted to the air conditioner.
That is to say, in the temperature control mode around the user, the temperature around the user T3 can be detected by the infrared detection device or the temperature around the user T3 can be obtained by the wearable device, the temperature around the user T3 is compared with a third preset value T3c by the control module 3, and when T3 is greater than T3c, the control module 3 increases the working frequency of the compressor to increase the refrigeration capacity and reduce the temperature around the user; when the T3 is less than the T3c, the control module 3 reduces the working frequency of the compressor to reduce the refrigerating capacity and increase the temperature of the user; when T3 equals T3c, indicating that the current operating parameters are satisfactory, the control module 3 maintains the operating frequency of the compressor.
In addition, in order to reduce the influence of errors and prevent frequent switching of the operation mode of the air conditioner, a certain error, for example, ± 0.5 ℃, is allowed when determining the relationship between the temperature around T3 and the third preset value T3 c. Specifically, a temperature threshold Δ T may be preset (for example, Δ T may be 0.5), and when the temperature T3 around the body is greater than a third preset value T3c plus the temperature threshold Δ T, i.e., T3> T3c +0.5, the control module 3 decreases the operating frequency of the compressor; when the temperature T3 around is less than the third preset value T3c minus the temperature threshold Δ T, i.e. T3 is less than T3c-0.5, the control module 3 reduces the operating frequency of the compressor; when the temperature T3 around the body is greater than or equal to the third preset value T3c minus the temperature threshold Δ T and less than or equal to the third preset value T3c plus the temperature threshold Δ T, i.e., T3c-0.5 is greater than or equal to T3 is greater than or equal to T3c +0.5, the control module 3 keeps the operating frequency of the compressor unchanged.
In summary, in the embodiment of the present invention, the control module 3 specifically includes a dynamic wind control unit, a comparison calculation unit, and a compressor control unit. After a user inputs a dynamic wind starting instruction through a remote controller, the receiving module 1 receives the dynamic wind starting instruction, and the dynamic wind control unit control module 3 can control the dynamic change of the rotating speed of a wind wheel of the air conditioner and/or control the dynamic swing of a wind guide mechanism of the air conditioner to form a dynamic wind effect. Meanwhile, the room temperature detection module 2 obtains the room temperature T1, and the comparison calculation unit compares the room temperature T1 with the first preset value T1c to determine the operation mode of the air conditioner. When the comparison calculation unit judges that the room temperature T1 is lower than the first preset value T1c, the air outlet temperature T2 of the air conditioner or the temperature T3 of the user at the side of the room is obtained, the air outlet temperature T2 is compared with the second preset value T2c or the temperature T3 at the side of the room is compared with the third preset value T3c, and the compressor control unit controls the working frequency of the compressor of the air conditioner according to the comparison result.
In summary, according to the control device of the air conditioner provided in the embodiment of the present invention, the receiving module receives a dynamic wind start instruction input by a user, and the room temperature detection module detects a room temperature, after receiving the dynamic wind start instruction, the control module adjusts an air outlet speed and/or an air direction of the air conditioner according to the dynamic wind start instruction, and simultaneously detects whether the room temperature is lower than a first preset value, and if the room temperature is lower than the first preset value, obtains an air outlet temperature of the air conditioner or a temperature around a user in the room, and controls an operating frequency of a compressor of the air conditioner according to the air outlet temperature of the air conditioner or the temperature around the user in the room. Therefore, the device can blow dynamic wind with proper temperature to the user by controlling the wind outlet speed and/or the wind direction and the temperature of the air outlet, and meets the requirements of the user on the dynamic wind and the comfortable temperature of the air outlet, thereby improving the monotonous feeling of the air blowing of the air conditioner, enabling the air blowing of the air conditioner to be more natural, providing comfortable air blowing feeling for the user, and simultaneously reducing the energy consumption of the air conditioner and saving energy.

In addition, on the air conditioner with the fresh air ventilator, by the control method and the control device, after the fresh air ventilator is started, outdoor fresh air can be sucked into a room, and meanwhile, the dynamic swing of the air guide mechanism or the dynamic change of the rotating speed of the wind wheel is controlled, so that the fresh air sucked into the room from the outside is mixed with the indoor air and then is dynamically blown out, and dynamic fresh air is formed.
