In the related art, a user needs proper temperature and proper air when using a bathroom or a bathroom, but the conventional air conditioner cannot discharge indoor air flow during heating or refrigerating or cannot adjust indoor temperature during exhausting the indoor air flow, so that the use experience of the user is affected.
In view of this, an aspect of the present application provides a control method of an air conditioner, referring to fig. 1, the control method includes:
s1, adjusting the indoor temperature to meet the set temperature.
Here, the indoor temperature refers to an ambient temperature of an indoor space in which the air conditioner 1 is located. The set temperature may be a preset temperature set in advance of the air conditioner 1, or may be a target temperature selected by the user. Thus, the air conditioner 1 can control the indoor temperature to the set temperature, and the user can perform daily activities at a proper temperature.
For example, in some embodiments, before the indoor temperature is adjusted to meet the set temperature in S1, the control method includes S101, where the preset temperature is the set temperature. It is to be understood that the preset temperature herein may refer to a temperature preset at the time of shipment of the air conditioner 1. For example, when the air conditioner 1 is shipped, an operator sets the set temperature to a preset temperature, for example, the set temperature is between 22 ℃ and 26 ℃. Therefore, the set temperature can be preset according to the comfort of the human body, the user can not set the temperature additionally later, and the operation steps are reduced.
In some embodiments, before the indoor temperature is adjusted to meet the set temperature in S1, the control method includes receiving temperature adjustment information to determine the target temperature as the set temperature in S102. For example, the user may transmit temperature adjustment information to select a temperature value of the set temperature through a remote controller or a control panel of the air conditioner 1, and the control device of the air conditioner 1 determines the set temperature according to the temperature adjustment information.
In some embodiments, before the indoor temperature is adjusted to meet the set temperature in S1, the control method includes determining one of the preset temperature and the target temperature as the set temperature in S103.

In some embodiments, 103, determining one of the preset temperature and the target temperature as the set temperature includes S1031, accepting selection information to determine one of the preset temperature and the target temperature as the set temperature. For example, the user may transmit the selection information through a remote controller, a mobile terminal such as a cellular phone, or a control panel of the air conditioner 1. After receiving the temperature adjustment information, the control device of the air conditioner 1 may determine that the target temperature set by the user is the set temperature or that the preset temperature is the set temperature. Like this, the controllability is high, and the flexibility is strong, can satisfy the different temperature demands of user, and the simple operation.
S2, adjusting the outdoor negative pressure of the outdoor air duct to be larger than the indoor negative pressure of the indoor air duct.
Here, the outdoor negative pressure is larger than the indoor negative pressure, and a driving force for discharging the air flow from the indoor to the outdoor can be generated.
For example, referring to fig. 2 and 3, in one embodiment, the air conditioner 1 includes a casing 16, a partition 161 is disposed in the casing 16, the partition 161 divides a space in the casing 16 into an independent indoor chamber 16a and an outdoor chamber 16b, so that air flows in the indoor chamber 16a and the outdoor chamber 16b can be prevented from affecting each other, a ventilation opening a may be provided in the partition 161 or the casing 16, the indoor chamber 16a is a part of the indoor air duct 11, and the outdoor chamber 16b is a part of the outdoor air duct 12. The indoor negative pressure is the negative pressure generated by the indoor cavity 16a at the end of the air exchange valve 15 during the operation of the indoor fan 13, and the outdoor negative pressure is the negative pressure generated by the outdoor cavity 16b at the end of the air exchange valve 15 during the operation of the outdoor fan 14. Thus, by adjusting the relationship between the indoor negative pressure and the outdoor negative pressure, the indoor air flow is caused to be effectively discharged to the outside.
And S3, opening the ventilation valve to communicate the indoor air duct and the outdoor air duct, so that indoor air flow can be discharged outdoors through the indoor air duct and the outdoor air duct.
Illustratively, the vent valve 15 is capable of blocking vent A to close vent A; the ventilation valve 15 can avoid the vent a to open the vent a. Specifically, the ventilation valve 15 is opened, the ventilation opening a is communicated with the indoor air duct 11 and the outdoor air duct 12, indoor air flows enter the indoor air duct 11 through the indoor air inlet, part of indoor air flows flow back to the indoor space through the indoor air outlet, part of indoor air flows enter the outdoor air duct 12 through the ventilation opening a, and then are discharged to the outdoor space through the outdoor air outlet.
Thus, by opening the ventilation valve 15, the indoor air duct 11 and the outdoor air duct 12 are communicated, and part of indoor air flow can be discharged from the room to the outside under the condition that the outdoor negative pressure is greater than the indoor negative pressure, so that the indoor air is cleaned.
In some embodiments, the air conditioner 1 includes a valve motor 17, such as a stepper motor, and the valve motor 17 may drive the ventilation valve 15 to rotate according to the electrical signal, so as to open or close the ventilation valve 15, thereby improving the automation degree.
The control method provided by the embodiment of the application not only can adjust the indoor temperature to meet the set temperature, but also can discharge part of indoor air flow outdoors while adjusting the indoor temperature, thereby meeting the requirements of users on temperature, discharging air with peculiar smell, having the functions of temperature control and clean indoor air flow, improving the indoor environment comfort level and improving the use experience of users.
It should be noted that the order of steps S1, S2 and S3 may not be limited, and in an exemplary embodiment, step S1 may be performed first, then step S2 may be performed, and then step S3 may be performed. Firstly, the indoor temperature is regulated, on the premise that the indoor temperature meets the set temperature, then, the outdoor negative pressure of the outdoor air duct 12 of the air conditioner 1 is regulated to be larger than the indoor negative pressure of the indoor air duct 11, driving force is provided for discharging indoor air flow outdoors, and finally, the ventilation valve 15 is opened to communicate the indoor air duct 11 with the outdoor air duct 12, so that the indoor air flow can be discharged outdoors after passing through the indoor air duct 11 and the outdoor air duct 12.
In another embodiment, step S3 may be performed first, then step S2 may be performed, and then step S1 may be performed. In yet another embodiment, step S3 may be performed first, then step S1 may be performed, and then step S2 may be performed. Step S3 is performed before step S2. I.e., the ventilation valve 15 is opened first, and then the outdoor negative pressure of the outdoor air duct 12 of the air conditioner 1 is adjusted to be greater than the indoor negative pressure of the indoor air duct 11.
In yet another embodiment, step S2 may be performed first, then step S1 may be performed, and then step S3 may be performed.
In one embodiment, before the indoor temperature is adjusted to meet the set temperature, the control method includes S110, turning on the refresh cooling mode or the refresh heating mode. In this way, the air conditioner 1 may enter a cooling and synchronous exhausting mode, or may enter a heating and synchronous exhausting mode. For example, the user can select the fresh cooling mode or the fresh heating mode through a remote controller, a mobile terminal such as a mobile phone or a control panel, and the operation is convenient.
In one embodiment, S110, the refresh cooling mode or the refresh heating mode is turned on, which includes obtaining the concentration of the odor through the odor sensor, and turning on the refresh cooling mode or the refresh heating mode according to the concentration of the odor. The air conditioner 1 integrates an odor sensor, and when the odor sensor detects that the concentration of indoor odor reaches a threshold value, the air conditioner automatically starts a fresh refrigeration mode or a fresh heating mode, does not need to be manually started, and has high automation degree.
In one embodiment, S1, adjusting the indoor temperature to meet the set temperature includes:
and S11, if the indoor heat exchanger of the air conditioner is used as an evaporator, adjusting the indoor temperature to be lower than or equal to the set temperature.
Illustratively, the air conditioner 1 turns on the fresh cooling mode, the indoor heat exchanger is an evaporator, and the outdoor heat exchanger is a condenser accordingly. The refrigerant can be changed from a gaseous state to a liquid state by heat release in the condenser, and from a liquid state to a gaseous state by heat absorption in the evaporator. That is, when the indoor heat exchanger is switched to the evaporator, the air conditioner 1 is in a refrigerating state at this time, in order to enable the user to obtain better use experience, such as the user's own temperature difference feeling, ventilation is performed at the indoor temperature lower than or equal to the set temperature, so that the ventilation can be prevented from affecting the indoor temperature, and the peculiar smell gas can be discharged.
Therefore, under the condition that the indoor heat exchanger is switched to the evaporator, refrigeration synchronous ventilation is realized, for example, a user can adopt the refrigeration refreshing mode in summer with higher temperature, and the use experience of the user is improved.
And S12, if the indoor heat exchanger is used as a condenser, adjusting the indoor temperature to be higher than or equal to the set temperature.
Illustratively, the air conditioner 1 is turned on in a fresh air cooling mode, and when the indoor heat exchanger is switched to the condenser, the air conditioner 1 is in a heating state. The indoor temperature is quickly increased to be higher than the set temperature, synchronous ventilation is performed when the indoor temperature is higher than the set temperature, the large fluctuation of the indoor temperature caused by the ventilation process is avoided, and a user can still enjoy proper temperature and fresh air.
Therefore, under the condition that the indoor heat exchanger is switched to the condenser, heating synchronous ventilation is realized, for example, a user can adopt the heating refreshing mode in winter with lower temperature, and the use experience of the user is improved.
In an embodiment, S2, adjusting the outdoor negative pressure of the outdoor air duct of the air conditioner to be greater than the indoor negative pressure of the indoor air duct of the air conditioner includes:
s21, adjusting the rotating speed of an outdoor fan of the air conditioner to be larger than that of an indoor fan of the air conditioner.
Here, the rotational speed of the outdoor fan 14 is adjusted to be greater than the rotational speed of the outdoor fan 14 such that the outdoor negative pressure generated by the outdoor chamber 16b at the ventilation valve 15 end is greater than the indoor negative pressure generated by the indoor chamber 16a at the ventilation valve 15 end, and the indoor air flow has a driving force to be discharged to the outside.
The speed of the outdoor fan 14 is adjusted to be greater than the speed of the indoor fan 13, including but not limited to the following: the rotating speed of the outdoor fan 14 is increased, and the rotating speed of the indoor fan 13 is unchanged; the rotating speed of the outdoor fan 14 is unchanged, and the rotating speed of the indoor fan 13 is reduced; the rotating speed of the outdoor fan 14 is increased, and the rotating speed of the indoor fan 13 is reduced; the rotation speed of the outdoor fan 14 is increased, and the operation of the indoor fan 13 is stopped.
In some embodiments, the outdoor fan is configured as a centrifugal fan and the indoor fan is configured as a cross-flow fan.
Under the condition that the rotating speeds are the same, the air quantity of the centrifugal fan is larger than that of the cross flow fan, the outdoor fan 14 adopts the centrifugal fan, the indoor fan 13 adopts the cross flow fan, and the outdoor negative pressure is more convenient to adjust than the indoor negative pressure, so that part of indoor air flow is discharged outdoors more rapidly.
In an embodiment, the opening and closing angle of the ventilation valve is between 0 and 90 degrees, wherein the outdoor air duct and the indoor air duct are in a blocking state under the condition that the opening and closing angle of the ventilation valve is 0 degrees, and the outdoor air duct and the indoor air duct are in a completely opened state under the condition that the opening and closing angle of the ventilation valve is 90 degrees. That is, in the case where the opening and closing angle of the ventilation valve 15 is 0 °, no air flow can be circulated between the outdoor air duct 12 and the indoor air duct 11. Under the condition that the opening and closing angle is 90 degrees, the flow cross section of the vent A reaches the maximum. Here, the air displacement of the indoor air flow is controlled by controlling different opening and closing angles of the air exchange valve 15, so that the indoor cleaning effect is achieved.
For example, referring to fig. 2 and 3, one end of the ventilation valve 15 is rotatably disposed on the partition 161 to close or open the ventilation opening a. When the included angle between the ventilation valve 15 and the partition 161 is 0 °, that is, when the opening and closing angle of the ventilation valve 15 is 0 °, the ventilation valve 15 seals the ventilation opening a, and at this time, the indoor air flow cannot flow to the outdoor chamber 16b through the ventilation opening a, that is, the air displacement of the indoor air flow flowing from the indoor chamber 16a to the outdoor chamber 16b through the ventilation opening a is minimum; when the included angle between the ventilation valve 15 and the partition 161 is 90 degrees, that is, when the opening and closing angle of the ventilation valve 15 is 90 degrees, the ventilation valve 15 completely avoids the ventilation opening a. In the case where the opening and closing of the ventilation valve 15 is larger than 0 ° and smaller than any angle between 90 °, the ventilation valve 15 partially avoids the ventilation opening a, and the amount of exhaust can be adjusted by adjusting the opening and closing angle of the ventilation valve 15.
In one embodiment, the control method includes:
s4, periodically detecting the indoor temperature, and adjusting the pressure difference between the outdoor negative pressure and the indoor negative pressure according to the indoor temperature.
Here, the pressure difference can be adjusted by periodically detecting the indoor temperature to ensure that the indoor temperature satisfies the set temperature, and avoid the exhaust gas from greatly affecting the indoor environment temperature. For example, after the indoor temperature is determined to meet the set temperature, the pressure difference between the indoor negative pressure and the outdoor negative pressure can be adjusted according to the indoor temperature so as to change the exhaust amount of the indoor air flow, thereby achieving the purposes of cleaning the indoor air flow and controlling the indoor temperature, and having high efficiency.
The indoor temperature may be periodically detected using a set period, the duration of which is not limited, and the set period may be between 2min (minutes) and 6min (minutes), for example. Therefore, the detection duration is moderate, and the effects of temperature control, energy conservation and emission reduction are considered. Especially, in the case that the air conditioner 1 provided by the embodiment of the application is used for a bathroom, the duration of using the bathroom by a user is relatively short, and the setting period can be experienced better during the use period of the user.
It will be appreciated that the greater the pressure difference between the outdoor negative pressure and the indoor negative pressure, the more indoor air flow is discharged, and that the rotational speed of the outdoor fan 14 and the rotational speed of the indoor fan 13 may be adjusted for rapid discharge of the indoor air flow. Referring to fig. 4, the abscissa indicates the rotational speed difference between the outdoor fan 14 and the indoor fan 13, and the ordinate indicates the exhaust amount of the indoor air flow, and it can be seen that the greater the rotational speed difference between the outdoor fan 14 and the indoor fan 13, the greater the exhaust amount, and the more the indoor air flow is exhausted. Therefore, under the condition that the indoor temperature meets the set temperature, the aim of rapidly discharging the indoor air flow can be achieved by increasing the rotation speed difference of the two fans.
In one embodiment, S4, the step of adjusting the pressure difference between the outdoor negative pressure and the indoor negative pressure according to the indoor temperature includes:
and S41, if the indoor heat exchanger is used as an evaporator and the indoor temperature is lower than the set temperature, regulating the pressure difference between the outdoor negative pressure and the indoor negative pressure so as to enable the pressure difference to be inversely related to the indoor temperature.
In the cooling and refreshing mode, the indoor heat exchanger is used as an evaporator, the indoor temperature is lower than the set temperature, and then the pressure difference between the outdoor negative pressure and the indoor negative pressure is regulated, so that the pressure difference and the indoor temperature are in a negative correlation. It can be understood that the negative correlation between the pressure difference and the indoor temperature means that the pressure difference between the outdoor negative pressure and the indoor negative pressure is increased by taking the set temperature as a limit, for example, the set temperature is 24 ℃, when the indoor temperature is greatly different from the set temperature, for example, the indoor temperature is 18 ℃, so that the indoor exhaust amount is increased at a lower temperature, the indoor cleaning effect is quickly achieved, the waiting time of a user is reduced, and the cooling feeling of the user in summer is not influenced; when the indoor temperature is smaller than the set temperature, if the indoor temperature is 23 ℃, the pressure difference between the outdoor negative pressure and the indoor negative pressure is correspondingly reduced, so that the exhaust amount of indoor air flow is reduced, and the somatosensory temperature of a user is preferentially ensured. That is, the amount of exhaust air of the indoor air flow affects the indoor temperature to some extent because the air flow discharged from the indoor is intercepted as a part of the indoor circulation, which results in a reduction of the intake air amount of the indoor fan 13, affecting the heating/cooling effect of the air conditioner 1.
In one embodiment, if the indoor heat exchanger is used as a condenser and the indoor temperature is higher than the set temperature, the pressure difference between the outdoor negative pressure and the negative pressure is adjusted so that the pressure difference and the indoor temperature are positively correlated.
In the heating fresh mode, the indoor heat exchanger is used as a condenser, the indoor temperature is higher than the set temperature, and then the pressure difference between the outdoor negative pressure and the indoor negative pressure is adjusted so that the pressure difference has a positive correlation with the indoor temperature. It can be understood that the positive correlation between the pressure difference and the indoor temperature means that the pressure difference between the outdoor negative pressure and the indoor negative pressure is increased by taking the set temperature as a limit, for example, the set temperature is 24 ℃, and when the indoor temperature is larger than the set temperature, for example, the indoor temperature is 28 ℃, so that the exhaust amount of the indoor air flow is increased at a higher temperature, the indoor cleaning effect is quickly achieved, the waiting time of a user is reduced, and the warm feeling of the user in winter is not influenced; when the indoor temperature is smaller than the set temperature, if the indoor temperature is 23 ℃, the pressure difference between the outdoor negative pressure and the indoor negative pressure is correspondingly reduced, so that the exhaust amount of indoor air flow is reduced, and the somatosensory temperature of a user is preferentially ensured.
In one embodiment, the step of adjusting the difference between the outdoor negative pressure and the indoor negative pressure comprises: and S5, increasing the rotating speed of an outdoor fan of the air conditioner so as to change the rotating speed difference between the rotating speed of the outdoor fan and the rotating speed of the indoor fan. For example, the rotation speed of the outdoor fan 14 may be separately increased to further increase the pressure difference, so that the operation is convenient.
In one embodiment, the step of adjusting the difference between the outdoor negative pressure and the indoor negative pressure includes S6, reducing the rotational speed of the indoor fan of the air conditioner to change the rotational speed difference between the rotational speed of the outdoor fan and the rotational speed of the indoor fan. For example, the rotational speed of the indoor fan 13 may be separately decreased to further increase the pressure difference.
It is understood that step S5 may be implemented separately. Step S6 may be implemented separately. Step S5 and step S6 may be performed simultaneously.
In one embodiment, the control method includes: s7, periodically detecting the indoor temperature, and adjusting the opening and closing angle of the air exchange valve according to the indoor temperature.
Here, by periodically detecting the indoor temperature, after determining that the indoor temperature meets the set temperature, the opening and closing angle of the ventilation valve 15 is adjusted according to the indoor temperature so as to change the exhaust amount of the indoor air flow, thereby achieving the purposes of cleaning the indoor air flow and controlling the indoor temperature with high efficiency.
The duration of the set period is not limited, and the set period may be between 2min (minutes) and 6min (minutes), for example. Therefore, the detection duration is moderate, and the effects of temperature control, energy conservation and emission reduction are considered. Especially, in the case that the air conditioner 1 provided by the embodiment of the application is used for a bathroom, the duration of using the bathroom by a user is relatively short, and the setting period can be experienced better during the use period of the user.
In one embodiment, the step of adjusting the opening and closing angle of the ventilation valve according to the indoor temperature includes: and S71, if the indoor ventilator is used as an evaporator and the indoor temperature is lower than the set temperature, adjusting the opening and closing angle of the ventilation valve so that the opening and closing angle is inversely related to the indoor temperature.
Illustratively, in the cooling fresh mode, the indoor heat exchanger is used as an evaporator, and the indoor temperature is lower than the set temperature, and then the opening and closing angle of the ventilation valve 15 is adjusted so that the opening and closing angle has a negative correlation with the indoor temperature. It can be understood that the negative correlation between the opening and closing angle and the indoor temperature means that the opening and closing angle of the ventilation valve 15 is increased by taking the set temperature as a limit, for example, the set temperature is 24 ℃, when the indoor temperature is greatly different from the set temperature, for example, the indoor temperature is 18 ℃, for example, the opening and closing angle is increased to 90 degrees, and the ventilation opening A is fully opened, so that the time for exhausting indoor airflow to the outside can be reduced, and the ventilation valve is efficient and convenient. The exhaust amount of indoor air flow is increased at a lower temperature, so that the indoor cleaning effect is quickly achieved, the waiting time of a user is reduced, and the warm feeling of the user in summer is not influenced; when the indoor temperature is smaller than the set temperature, if the indoor temperature is 23 ℃, the opening and closing angle of the ventilation valve 15 is correspondingly reduced so as to reduce the exhaust amount of indoor air flow and preferentially ensure the somatosensory temperature of the user.
In an embodiment, if the indoor heat exchanger is used as a condenser and the indoor temperature is higher than the set temperature, the opening and closing angle of the ventilation valve is adjusted so that the opening and closing angle and the indoor temperature are positively correlated.
Illustratively, in the heating fresh mode, the indoor heat exchanger serves as a condenser, and the indoor temperature is higher than the set temperature, and then the opening and closing angle of the ventilation valve 15 is adjusted such that the opening and closing angle is in positive correlation with the indoor temperature. It can be understood that the positive correlation between the opening and closing angle and the indoor temperature means that the opening and closing angle of the ventilation valve 15 is increased to 90 ° when the difference between the indoor temperature and the set temperature is larger, such as 24 ℃, and the indoor temperature and the set temperature is 25 ℃, such that the ventilation opening a is fully opened, so that the air displacement of indoor air flow is increased at a higher temperature, the indoor cleaning effect is quickly achieved, the waiting time of a user is reduced, and the warm feeling of the user in winter is not affected; when the indoor temperature is smaller than the set temperature, if the indoor temperature is 23 ℃, the opening and closing angle of the ventilation valve 15 is correspondingly reduced so as to reduce the exhaust amount of indoor air flow and preferentially ensure the somatosensory temperature of a user.
In one embodiment, step S4 and step S7 may be performed simultaneously. Here, when the indoor temperature satisfies the set temperature, the opening and closing angle of the ventilation valve 15 can be increased while the pressure difference between the outdoor negative pressure and the indoor negative pressure is increased, and the indoor air flow can be more rapidly discharged outdoors by combining the two, thereby improving the exhaust efficiency.
