The present embodiment also provides a control method of the air conditioner 10, which may be performed by the controller 400 in the air conditioner 10, and fig. 2 is a schematic diagram of the control method of the air conditioner 10 according to an embodiment of the present invention. A control method of an air conditioner 10 according to an embodiment of the present invention may generally include:
step S202: a first ambient temperature Ta, a second ambient temperature Tm, and a body surface temperature Tc of the human body in the temperature-controlled area are obtained, where the first ambient temperature Ta is an ambient temperature around the indoor unit 100 detected by the indoor unit 100 of the air conditioner 10, and the second ambient temperature Tm is an ambient temperature around the remote controller 300 detected by the remote controller 300 of the air conditioner 10.

Step S206: the cooling state of the air conditioner 10 is adjusted according to the calibration temperature difference Tz.
In step S202, the first ambient temperature Ta may be obtained by a temperature sensor provided on the indoor unit 100, for example, a temperature sensor provided at an indoor air outlet of the indoor unit 100. The second ambient temperature Tm may be obtained by a temperature sensor provided on the remote controller 300. The temperature-controlled area may be an indoor space where the indoor unit 100 is located, and the human body surface temperature Tc may be obtained by an infrared device of the intelligent terminal and then transmitted to the controller 400 of the air conditioner 10, or may be directly obtained by an infrared device of the indoor unit 100, and the like, wherein if there are a plurality of human bodies in the temperature-controlled area, an average value of the obtained human body surface temperatures of the plurality of human bodies is taken as the human body surface temperature Tc.
In some embodiments, the air conditioner 10 may obtain the first ambient temperature Ta, the second ambient temperature Tm and the human body surface temperature Tc within the temperature adjusting area in real time, so as to perform the steps S202, S204 and S206 in real time, so that the air conditioner 10 may adjust the cooling state of the air conditioner 10 according to the indoor ambient temperature required by the user in real time.
In other embodiments, the method for controlling the air conditioner 10 further includes obtaining a user command for searching the remote controller 300, and executing step S202 according to the user command. A user may send a user command to search for the remote controller 300 through an input device on the indoor unit 100 or an input device on the smart terminal, where the input device may be a physical button or a control panel, and the smart terminal may be a mobile phone or a tablet computer.
If the air conditioner 10 obtains the user command for searching the remote controller 300, step S202 to step S206 are executed. When the air conditioner 10 acquires a user instruction to search the remote controller 300, it may also transmit an instruction to the remote controller 300 so that the remote controller 300 outputs a prompt signal indicating the position of the remote controller 300 in accordance with the instruction. The position of the remote controller 300 may be obtained by a positioning device in the remote controller 300, for example, the positioning device may be a distance sensor for detecting a distance between the remote controller 300 and the indoor unit 100, and the prompt signal may be an audio signal or an optical signal. For example, the user may be prompted by shaking or lighting the remote controller 300 to indicate the location of the remote controller 300; the remote controller 300 can also emit smell by heating the aromatherapy in the remote controller 300 to prompt the user of the position information of the remote controller 300; the position information of the remote controller 300 may also be sent back to the indoor unit 100, for example, the distance between the remote controller 300 and the indoor unit 100 is sent back to the indoor unit 100, so that the indoor unit 100 sends the position of the remote controller 300, the indoor unit 100 may display the position information of the remote controller 300 through a panel of the indoor unit 100, may also send voice information to broadcast the position information of the remote controller 300, and may also send the position information of the remote controller 300 to an intelligent terminal, so that a user receives the position information of the remote controller 300 in real time.
If the air conditioner 10 does not obtain the user command for searching the remote controller 300, the frequency of the compressor 200 of the air conditioner 10 and the rotation speed of the indoor fan 110 may be maintained.
In some embodiments, the controller 400 of the air conditioner 10 may further identify a user identity according to the user instruction, acquire a prompt mode corresponding to the user identity, and send an instruction corresponding to the prompt mode to the remote controller 300, so that the remote controller 300 outputs a prompt signal of the position of the remote controller 300 according to the prompt mode corresponding to the instruction. The method for identifying the user identity may be fingerprint identification, facial identification, voice identification, or the like. The user may preset a corresponding relationship between the user identity and the prompt mode, and when the remote controller 300 receives the instruction command corresponding to the prompt mode, the location information of the remote controller 300 is output in the prompt mode corresponding to the instruction command, for example, the user a may preset an identity corresponding to the prompt mode in which the remote controller 300 emits a scent, and when the remote controller 300 receives the instruction command corresponding to the prompt mode in which the remote controller 300 emits a scent, the remote controller 300 may heat the aroma in the remote controller 300 through the heating module in the remote controller 300 to prompt the user of the location of the remote controller 300.
For another example, the air conditioner 10 may obtain the user identity by facial recognition, and the B user may set a corresponding relationship between the facial information of the B user and the prompt mode in the air conditioner 10 in advance, for example, the facial information of the B user corresponds to the prompt mode for illuminating the remote controller 300, when the air conditioner 10 sends an instruction to the remote controller 300, the user identity is further identified according to the user instruction, the prompt mode corresponding to the user identity for illuminating the remote controller 300 is obtained, and an instruction corresponding to the prompt mode for illuminating the remote controller 300 is sent to the remote controller 300, so that the remote controller 300 illuminates, thereby facilitating the user to find the remote controller 300, saving the time for the user to find the remote controller 300, and improving the user experience.
In step S204, calculating the calibration temperature difference Tz may determine the calibration coefficient K according to the ratio Tm/Ta of the second environment temperature Tm to the first environment temperature Ta, for example, K may be taken as the ratio Tm/Ta, and a product K (Tc-Tm) of the calibration coefficient K and the temperature difference (Tc-Tm) is taken as the calibration temperature difference Tz.
In step S206, if the indoor unit 100 is in the cooling mode, it may be determined whether the calibrated temperature difference Tz is greater than a preset first temperature difference threshold F1 or less than a preset second temperature difference threshold F2, where the first temperature difference threshold F1 is greater than or equal to the second temperature difference threshold F2, the first temperature difference threshold F1 and the second temperature difference threshold F2 may be any values between 8 and 20 ℃, for example, the first temperature difference threshold F1 is 20 ℃ and the second temperature difference threshold F2 is 8 ℃, or the first temperature difference threshold F1 is 15 ℃ and the second temperature difference threshold F2 is 10 ℃, or the first temperature difference threshold F1 is 12 ℃ and the second temperature difference threshold F2 is 12 ℃.
Wherein, in case the calibrated temperature difference Tz is greater than the first temperature difference threshold value F1, the cooling capacity of the indoor unit 100 is reduced. At this time, it is shown that the temperature difference (Tc-Tm) between the human body surface temperature Tc of the user and the second environment temperature Tm close to the environment where the user is located is large, and the temperature is difficult to rise back in a short time, and at this time, in order to avoid that the indoor environment temperature is too low to affect the user experience, and in order to save energy, the cooling capacity of the indoor unit 100 is reduced. The reduction of the cooling capacity of the indoor unit 100 may be achieved by reducing the operating frequency of the compressor 200 of the air conditioner 10 and/or reducing the rotational speed of the indoor fan 110 of the indoor unit 100.
In the case where the calibrated temperature difference Tz is smaller than the second temperature difference threshold value F2, the cooling capacity of the indoor unit 100 is increased. At this time, it is shown that the temperature difference (Tc-Tm) between the human body surface temperature Tc of the user and the second environment temperature Tm close to the environment where the user is located is small, and it is difficult to rapidly cool down in a short time, and at this time, the cooling capacity of the indoor unit 100 is increased in order to avoid that the user experience is affected by too high indoor environment temperature. The increase of the cooling capacity of the indoor unit 100 may be performed by increasing the operation frequency of the compressor 200 of the air conditioner 10 and/or increasing the rotation speed of the indoor fan 110 of the indoor unit 100.
In the case that the calibration temperature difference Tz is less than or equal to the first temperature difference threshold F1, and the calibration temperature difference Tz is greater than or equal to the second temperature difference threshold F2, the air conditioner 10 may maintain the cooling capacity of the indoor unit 100 constant, that is, the air conditioner 10 maintains the operation frequency of the compressor 200 and the rotation speed of the indoor fan 110 constant.
If the indoor unit 100 is in the heating mode, it may be determined whether the calibrated temperature difference Tz is greater than a preset first temperature difference threshold F1 or less than a preset second temperature difference threshold F2, where the first temperature difference threshold F1 is greater than or equal to the second temperature difference threshold F2, the first temperature difference threshold F1 and the second temperature difference threshold F2 may be any values between 8 ℃ and 20 ℃, for example, the first temperature difference threshold F1 is 20 ℃ and the second temperature difference threshold F2 is 8 ℃, or the first temperature difference threshold F1 is 15 ℃ and the second temperature difference threshold F2 is 10 ℃, or the first temperature difference threshold F1 is 12 ℃ and the second temperature difference threshold F2 is 12 ℃.
In the case where the calibration temperature difference Tz is greater than the first temperature difference threshold value F1, the heating capacity of the indoor unit 100 is increased. At this time, it is explained that the temperature difference (Tc-Tm) between the human body surface temperature Tc of the user and the second environment temperature Tm close to the environment where the user is located is large, and it is difficult to rapidly increase the temperature in a short time, and at this time, the heating capacity of the indoor unit 100 is increased in order to avoid the influence of the too low indoor environment temperature on the user experience. Increasing the heating capacity of the indoor unit 100 may be performed by increasing the operating frequency of the compressor 200 of the air conditioner 10 and/or increasing the rotational speed of the indoor fan 110 of the indoor unit 100.
In the case where the calibrated temperature difference Tz is smaller than the second temperature difference threshold value F2, the heating capacity of the indoor unit 100 is reduced. At this time, it is shown that the temperature difference (Tc-Tm) between the human body surface temperature Tc of the user and the second environment temperature Tm close to the environment where the user is located is small, and the temperature is not rapidly decreased in a short time, and at this time, in order to avoid that the user experience is affected by too high indoor environment temperature, and in order to save energy, the heating capacity of the indoor unit 100 is reduced. Reducing the heating capacity of the indoor unit 100 may be accomplished by reducing the operating frequency of the compressor 200 of the air conditioner 10 and/or reducing the rotational speed of the indoor fan 110 of the indoor unit 100.
In the case where the calibration temperature difference Tz is less than or equal to the first temperature difference threshold value F1 and the calibration temperature difference Tz is greater than or equal to the second temperature difference threshold value F2, the air conditioner 10 may maintain the heating capacity of the indoor unit 100 unchanged, that is, the air conditioner 10 maintains the operation frequency of the compressor 200 and the rotation speed of the indoor fan 110 unchanged.
Because the environment where the remote controller 300 is located is closer to the environment where the user is located, and the temperature difference (Tc-Tm) can reflect the indoor temperature required by the user, and because the temperature is transmitted from the indoor unit 100 to other areas, the first environment temperature Ta represents the temperature variation trend, and the temperature difference (Tc-Tm) is calibrated and calculated by using the first environment temperature Ta and the second environment temperature Tm to obtain the calibrated temperature difference Tz which can represent the variation trend of the environment temperature required by the user, the method enables the air conditioner 10 to judge the refrigeration state required by the user more accurately, thereby improving the adjustment effect of the air conditioner 10 on the indoor temperature and improving the user experience.
Fig. 3 is a flowchart illustrating a control method of the air conditioner 10 in the cooling mode according to an embodiment of the present invention. As shown in fig. 3, the execution flow of the control method of the air conditioner 10 in the cooling mode according to the embodiment of the present invention may include:
