Alternatively, the air conditioner may include a driving mechanism for driving the separation door 15 to rotate, and the separation door 15 may be automatically opened and closed to the separation opening 14 by driving the separation door 15 to rotate by the driving mechanism. For example, when the sub-machine 20 needs to be moved out of the main machine 10, the driving mechanism can be controlled to drive the separation door 15 to rotate so as to open the separation port 14, and the sub-machine 20 can automatically move out of the sub-machine cavity 13 through the separation port 14 and move to the indoor ground; when the submachine 20 needs to move into the submachine cavity 13 in the main machine 10, the submachine 20 can automatically move into the submachine cavity 13, and after the submachine 20 moves into the submachine cavity 13, the driving mechanism can be controlled to drive the separation door 15 to rotate so as to close the separation port 14.

The main body 10 may include a main body case 11 and a heat exchange air supply unit disposed in the main body case 11, and the main body case 11 is formed with an air return opening 111 and an air supply opening. The heat exchange air supply unit can comprise a heat exchanger component and a main fan component, when the main machine 10 works, the main fan component operates to drive external air to enter the main machine shell 11 from the air return opening 111, and after heat exchange with the heat exchanger component, the external air is blown out to the indoor through the air supply opening, so that the indoor environment temperature can be adjusted, and refrigeration/heating can be realized.

The main chassis 11 can define the sub-chassis cavity 13 and the accommodating cavity, the heat exchange air supply unit can be disposed in the accommodating cavity, and the sub-chassis 20 can be installed in the sub-chassis cavity 13. The sub-housing 13 and the accommodating housing can be separated, for example, a partition can be disposed in the main housing 11 to separate the space in the main housing 11 into the sub-housing 13 and the accommodating housing.

Optionally, the sub-machine cavity 13 may be located below the accommodating cavity, so that the sub-machine 20 is conveniently installed in the sub-machine cavity 13 or the sub-machine 20 is conveniently moved into the sub-machine cavity 13, and the sub-machine 20 is also conveniently taken out from the sub-machine cavity 13 or the sub-machine 20 is conveniently moved out of the sub-machine cavity 13 and moved to the indoor ground from the sub-machine cavity 13. Further, the bottom wall of the sub-machine cavity 13 can be used as the bottom wall of the main case 11, the bottom wall of the sub-machine cavity 13 is directly contacted with the ground, and the bottom wall of the sub-machine cavity 13 can be arranged to be thin, so that the sub-machine 20 can automatically move into the sub-machine cavity 13 from the indoor ground or automatically move onto the indoor ground from the sub-machine cavity 13.

The air conditioner may be a split type air conditioner, for example, the air conditioner may be a split floor type air conditioner or a split wall type air conditioner. When the air conditioner is a split air conditioner, the air conditioner includes an air conditioner indoor unit 100 and an air conditioner outdoor unit, and the air conditioner indoor unit 100 includes the host machine 10 and the slave machine 20. For example, when the air conditioner is a split floor type air conditioner, the air conditioning indoor unit 100 includes the main unit 10 and the sub unit 20 described above.

The sub-unit 20 may include a sub-housing 21 and an air supply processing unit, the air supply processing unit is disposed in the sub-housing 21, an air inlet and an air outlet are formed on the sub-housing 21, the air supply processing unit may include a sub-fan part 23, and the sub-unit 20 itself may not have a heating/cooling function. When the sub-unit 20 is in operation, the sub-fan unit 23 operates to drive the external air to enter the sub-enclosure 21 from the air inlet and then to be blown out to the room from the air outlet. The air supply processing unit can also comprise a humidifying module, so that the submachine 20 has a humidifying function, the indoor air can be humidified, and the indoor air quality is improved. When the slave unit 20 moves to the vicinity of the user, the slave unit 20 can quickly humidify the air in the vicinity of the user.

Optionally, the humidification module may include a humidification assembly and a water tank 25 for supplying water to the humidification assembly, the humidification module may further include a water pump, the water pump is used for conveying water in the water tank 25 to the humidification assembly, the humidification assembly may include a humidification support and a wet membrane assembly disposed on the humidification support, the water pump may pump water in the water tank 25 to the wet membrane assembly, and when the sub-fan unit 23 operates, the air flow may pass through the wet membrane assembly to take away water on the wet membrane assembly, so as to humidify the indoor air. Wherein, can be through the start and the stop of control water pump to can conveniently control the start and the stop of humidification module.

Optionally, the air supply processing unit may further include a purification module, so that the sub-unit 20 has both a humidification function and a purification function, and thus the sub-unit 20 may humidify and/or purify the indoor air, thereby improving the indoor air quality. When the slave unit 20 moves to the vicinity of the user, the slave unit 20 can quickly humidify and/or purify the air in the vicinity of the user.

Alternatively, the main body of the handset 20 may be substantially rectangular parallelepiped (see fig. 1) or substantially cylindrical (see fig. 2 and 3).

The sub machine 20 and the main machine 10 can communicate with each other, the sub machine 20 can transmit the collected information to the main machine 10, and the working condition of the sub machine 20 can be transmitted to the main machine 10; the master unit 10 may transmit the acquired information to the slave unit 20, and the operation condition of the master unit 10 itself may be transmitted to the slave unit 20. When the sub-unit 20 is detached from the main unit 10, the sub-unit 20 can move, for example, the bottom of the sub-unit 20 can be provided with wheels 22, and the wheels 22 can be universal wheels, so that the sub-unit 20 can move in any direction. For example, when the slave unit 20 is separated from the master unit 10 and placed on the floor, the slave unit 20 may collect the user position, and the slave unit 20 may automatically move to the vicinity of the user according to the user position to blow air to the user or humidify/purify air in the vicinity of the user. Of course, the slave unit 20 may be moved to another position according to a specific instruction from the user. The movement of the slave unit 20 in the room expands the blowing range of the master unit 10, which is advantageous for enhancing the fluidity of the indoor air and for uniformizing the indoor ambient temperature. After the main unit 10 is turned on, the sub-unit 20 can operate according to a user command or a set program, so that the whole air conditioner is more flexible to operate, has more diversified functions, and meets more requirements of users.

Wherein the host 10 is independently operable. The sub machine 20 can be controlled by the main machine 10 to work completely, and when the main machine 10 is not started, the sub machine 20 cannot work independently; the slave unit 20 may operate independently without being controlled by the master unit 10, and for example, when the master unit 10 is not turned on, the slave unit 20 itself may operate independently. When the main machine 10 and the sub machine 20 are both opened, communication can be realized between the main machine 10 and the sub machine 20, and information transmission between the main machine 10 and the sub machine 20 is conveniently realized, so that better control over the sub machine 20 is more conveniently realized, and better control over the main machine 10 can also be realized.

Optionally, the air inlet of the sub-machine 20 is located below the air outlet of the sub-machine 20. After the main unit 10 is turned on, the sub unit 20 may be moved to a predetermined position, for example, the sub unit 20 may be moved to a position near a user, and since the air inlet of the sub unit 20 is located at a lower position, the sub unit 20 may suck low air into the sub unit 20 and blow the air upward, which is beneficial to enhancing the flow of indoor air and is beneficial to uniformizing the indoor ambient temperature.

For example, when the air conditioner operates in a cooling mode, the cold air flow is lowered under the action of gravity, the submachine 20 can convey the air flow with lower temperature at the lower part to the higher part to realize air disturbance, and the air flow with lower temperature at the lower part is moved upwards to realize the relative lowering of the air temperature at the higher part, so that the air flow at the higher part has stronger fluidity; and a negative pressure zone is formed near the air inlet of the submachine 20, so that air flow with higher temperature at a high position flows downwards, and the relative increase of the air temperature at a low position is realized, thus the flow of indoor air can be accelerated and enhanced, and the homogenization of the indoor environment temperature is facilitated. When the submachine 20 moves to the position near the user, the temperature of the air near the user from top to bottom is integrally uniform, and the comfort is improved.

For example, when the air conditioner heats, the hot air flow rises under the action of its own gravity, the sub-machine 20 can convey the air flow with lower temperature at the lower part toward the higher part to realize air disturbance, and the air flow with lower temperature at the lower part moves upwards to realize the relative reduction of the air temperature at the higher part, so that the air flow at the higher part has stronger fluidity; and a negative pressure zone is formed near the air inlet of the submachine 20, so that air flow with higher temperature at a high position flows downwards, and the relative increase of the air temperature at a low position is realized, thus the flow of indoor air can be accelerated and enhanced, and the homogenization of the indoor environment temperature is facilitated. When the submachine 20 moves to the vicinity of the user, the temperature of the air near the user from top to bottom is integrally uniform, and the comfort is improved; moreover, the temperature migration around the sub-machine 20 is realized, the temperature at the lower part around the user is increased, the temperature increase of the lower limbs of the human body, such as the vicinity of the feet, is facilitated, and the lower limbs of the user feel warmer.

Alternatively, the sub-unit 20 itself may also be rotated, and the air supply direction of the sub-unit 20 in the horizontal direction may be adjusted and changed by the rotation of the sub-unit 20. For example, the handset 20 may include a base 24 and a main body of the handset 20 provided on the base 24, the main body of the handset 20 includes the above-mentioned air supply processing unit, wheels 22 may be provided on the bottom of the base 24 to move the handset 20, the main body of the handset 20 may rotate with respect to the base 24, and the handset 20 may include a mechanism for rotating the main body of the handset 20 with respect to the base 24. The rotation axis of the main body of the submachine 20 can extend along the up-down direction, and the main body of the submachine 20 can rotate 360 degrees relative to the base 24, so that no matter the user is in any indoor position or any direction, the submachine 20 can control the rotation mechanism of the submachine 20 to drive the main body of the submachine 20 to rotate to enable the air outlet of the submachine 20 to face the user according to the specific direction of the user relative to the submachine 20, and the adjustment and the change of the air outlet direction of the submachine 20 in the horizontal direction are conveniently realized.

In some embodiments of the present invention, the handset 20 may include a soft blowing mode and a powerful blowing mode, where the soft blowing mode has a shorter blowing distance, a lower blowing speed, and a lower blowing intensity than the powerful blowing mode. When the sub-unit 20 blows air towards the user, the sub-unit 20 can adopt a soft air blowing mode, and when the air is blown towards the user to quickly adjust the temperature of the area around the user, discomfort caused by direct blowing of strong wind to the human body can be avoided. When the slave unit 20 blows air toward the non-user area, for example, when the slave unit 20 blows air toward the return air inlet 111 of the master unit 10 or when the slave unit 20 blows air toward the air outlet of the master unit 10, the powerful blowing mode may be adopted. Specifically, when the sub-unit 20 supplies air toward the air return opening 111 of the main unit 10, the sub-unit 20 adopts a powerful air supply mode, which can further increase the air return amount of the main unit 10, can more quickly and better accelerate and strengthen the indoor air flow circulation, is more beneficial to the ambient temperature of the user to maintain or reach a comfortable temperature, and is more beneficial to the uniformity of the indoor ambient temperature. When the sub-machine 20 blows air toward the air outlet of the main machine 10, the sub-machine 20 adopts a powerful air blowing mode, which can better resist the air flow of the air outlet of the main machine 10 and better scatter the air flow blown out from the air outlet of the main machine 10, thereby better avoiding the discomfort caused by the direct blowing of the air flow blown out from the air outlet of the main machine 10 to the user.

The soft blowing mode and the powerful blowing mode of the slave unit 20 may be realized in the following manner, but are not limited thereto.

The first method is as follows: an air guide part for opening and closing an air outlet is arranged at the air outlet of the submachine 20, and a plurality of tiny air dispersing holes are formed in the air guide part, so that the submachine 20 has a soft air supply mode and a powerful air supply mode when in work, and the air guide part opens the air outlet to realize powerful air supply when in the powerful air supply mode; when the air supply mode is soft, the air guide part closes the air outlet, and the air flow passes through the air guide part and is scattered through the plurality of air scattering holes on the air guide part, so that the air outlet is softer.

The second method comprises the following steps: the sub-fan part 23 of the sub-machine 20 may include only one fan, which may be a centrifugal fan, an axial flow fan or a cross flow fan, and the switching of the air supply mode of the sub-machine 20 may be realized by adjusting the rotation speed of the fan, for example, the rotation speed of the fan of the sub-machine 20 in the soft air supply mode is less than the rotation speed of the fan of the sub-machine 20 in the powerful air supply mode.

The third method comprises the following steps: the sub-fan component 23 of the sub-machine 20 may be a counter-cyclone machine, the counter-cyclone machine includes two axial-flow wind wheels, the two axial-flow wind wheels may be respectively controlled by one motor, and the motors of the two axial-flow wind wheels may be independently controlled, so that soft air outlet and powerful air outlet of the counter-cyclone machine may be realized by controlling the motors of the two axial-flow wind wheels, and thus, a soft air supply mode and a powerful air supply mode may be switched.

The method is as follows: the sub-unit 20 may comprise different types of fans, for example the sub-fan unit 23 of the sub-unit 20 may comprise a first fan 231 and a second fan 232, wherein the first fan 231 may be a centrifugal fan and the second fan 232 may be an axial fan, a counter-rotating fan or a cross-flow fan. In the powerful blowing mode, the first fan 231 operates; in the soft blow mode, the second fan 232 is operated. In addition, when the second fan 232 is located at the downstream of the first fan 231, in the soft air supply mode, both the first fan 231 and the second fan 232 can work, and after at least a part of strong wind formed by the first fan 231 passes through the second fan 232, the airflow can be broken up, so that the outlet air is soft.

For example, in some specific examples of the present invention, referring to fig. 1 to 3, the air conditioner is a split floor type air conditioner, and the air conditioner includes an air conditioner indoor unit 100 and an air conditioner outdoor unit, where the air conditioner indoor unit 100 includes the master unit 10 and the slave unit 20 described above. The host machine 10 comprises a host machine shell 11 and a heat exchange air supply unit, a containing cavity and a sub machine cavity 13 which are arranged at intervals are defined in the host machine shell 11, the containing cavity is located above the sub machine cavity 13, the heat exchange air supply unit is installed in the containing cavity, and the sub machine 20 can be installed in the sub machine cavity 13. An air return opening 111 is formed in the rear side wall of the accommodating cavity, an air supply opening is formed in the front side wall of the accommodating cavity, and an opening and closing door 12 for opening and closing the air supply opening is arranged at the air supply opening.

The slave unit 20 can be separated from the master unit 10 and placed on the ground, and the slave unit 20 can be automatically moved as required.

Referring to fig. 4 and 5 (the direction of the arrow in fig. 4 and 5 is the flow direction of the airflow), specifically, the slave unit 20 includes a sub-housing 21 and an air supply processing unit, the air supply processing unit is disposed in the sub-housing 21, air inlets are formed at the left, right, and lower portions of the sub-housing 21, an air outlet is formed at the front upper side of the sub-housing 21, and the air inlets are located below the air outlet. The air supply processing unit comprises a sub-fan part 23 and a humidifying module, the humidifying module is arranged adjacent to the air inlet, the sub-fan part 23 comprises a first fan 231 and a second fan 232 which are arranged up and down, the second fan 232 is arranged above the first fan 231, the first fan 231 is a centrifugal fan, the second fan 232 is an axial-flow fan, the rotation axis of the first fan 231 extends along the left-right direction, the rotation axis of the second fan 232 extends forwards in the direction from back to front, for example, the included angle between the rotation axis of the second fan 232 and the horizontal plane can be 30-85 degrees, and for example, the included angle between the rotation axis of the second fan 232 and the horizontal plane can be 70 degrees. The second fan 232 has its air inlet side adjacent to the air outlet side of the first fan 231.

When only the first fan 231 works, the external air enters the first fan 231 from the air inlet, is blown out from the air outlet side of the first fan 231, and is finally blown out from the air outlet. When the first fan 231 and the second fan 232 both work, outside air enters the first fan 231 from the air inlet, is blown out from the air outlet side of the first fan 231, is softened by the second fan 232, and is finally blown out from the air outlet. In which, in the sub-machine 20 in the powerful blowing mode, only the first fan 231 of the first fan 231 and the second fan 232 is turned on; when the slave unit 20 is in the soft air supply mode, both the first fan 231 and the second fan 232 are turned on. When the first fan 231 operates, the humidifying module may be turned on, so that the humidification may be realized.

Referring to fig. 6 to 8, the control method of the air conditioner may include:

detecting and determining that water is in the water tank 25, wherein a water level sensor for detecting the water level can be arranged in the water tank 25, whether water is in the water tank 25 or not can be detected through the water level sensor, when no water is in the water tank 25, the water level in the water tank 25 can be continuously detected, and when water is in the water tank 25, the following steps can be executed;

determining that the humidification module stops working for more than a preset time, counting the time from the last time when the humidification module stops working to the present time, calculating whether the continuous working stop time of the humidification module exceeds the preset time, if the humidification module stops working for less than the preset time, continuing counting the time and detecting the water level in the water tank 25, and if the humidification module stops working for more than the preset time, executing the following steps;

the user can be reminded, for example, by sending information to the user terminal, or by flashing a light, giving an alarm, prompting with voice, or the like, and after receiving the reminder, the user can process the water tank 25, for example, the user can manually discharge water from the water tank 25, or the user can directly take out the water tank 25 and pour out the water in the water tank 25; after receiving the prompt, the user can control the submachine 20 to enter a drainage mode through the remote controller or the mobile terminal, water in the water tank 25 can be automatically drained after the submachine 20 enters the drainage mode, and when no water is detected in the water tank 25, the water in the water tank 25 is completely drained at the moment, and the submachine can exit the drainage mode;

alternatively, the slave set 20 may be automatically controlled to enter the drain mode to drain the water in the water tank 25 without prompting the user, the water in the water tank 25 may be automatically drained after the slave set 20 enters the drain mode, and when it is detected that there is no water in the water tank 25, the water in the water tank 25 is completely drained at this time, and the drain mode may be exited.

Optionally, the preset time period may be not less than 8h, for example, the preset time period may be 12h to 24h, so that the probability of bacteria breeding caused by long storage time and nonuse of water in the water tank 25 may be reduced, and waste of water resources may be reduced.

The "drainage mode" may be a mode in which the water in the water tank 25 is directly discharged to the outside of the slave set 20 without passing through a wet membrane module, for example, the slave set 20 may be moved into a toilet, and the slave set 20 may be controlled to enter the drainage mode so that the water in the water tank 25 is automatically discharged to a floor drain position of the toilet. For example, the water tank 25 may be externally connected with a drain pipe, the drain pipe may be provided therein with a drain valve or the drain port (the drain pipe is connected to the drain port) of the water tank 25 may be provided with a drain valve, and the lowest position of the drain port may be lower than the lowest position of the inner cavity of the water tank 25, so that the water in the water tank 25 may be discharged more thoroughly, and the water may be conveniently discharged by controlling the opening and closing of the drain valve.

Or, it can also be that set up the drain pump in the drain pipe, through opening and closing of drain pump, conveniently realize the drainage to set up the drain pump, take the water in the water tank 25 to the outside through the drain pump, can improve drainage efficiency, and can make the water exhaust in the water tank 25 more thorough. Wherein, in the process of draining, the water level in the water tank 25 is detected in real time, when no water is detected in the water tank 25, the drain valve or the drain pump can be closed, and the submachine 20 is controlled to move to the vicinity of the main machine 10 or move to the submachine cavity 13 of the main machine 10.

The "drainage mode" may also be that water in the water tank 25 is drained to the wet film assembly, and the water on the wet film assembly is taken away to the indoor air by the operation of the sub-fan part 23, that is, in this embodiment, the "drainage mode" is similar to the humidification mode, that is, the water in the water tank 25 enters the indoor air by the wet film assembly and the sub-fan part 23, the rotation speed of the sub-fan part 23 in the drainage mode is higher than that in the humidification mode, the operation speed of the water pump is higher, more water in the water tank 25 can be output to the wet film assembly per unit time, and the water on the wet film assembly can be evaporated faster by the action of the higher rotation speed of the sub-fan part 23, so that the water in the water tank 25 is consumed faster, and the drainage efficiency of the water in the water tank 25 is higher.

Whether water exists in the water tank 25 is judged by detecting the water level in the water tank 25 in real time, whether the stop work of the humidifying module exceeds the preset time is combined under the condition that water exists, when the stop work of the humidifying module exceeds the preset time, the probability of growing bacteria in the water tank 25 is increased, and at the moment, the water in the water tank 25 is reused for humidifying, so that the health of a human body can be influenced. Under the condition, the water in the water tank 25 is drained completely by reminding a user to treat the water tank 25 or automatically controlling the submachine 20 to enter an automatic drainage mode, so that water which is stored in the water tank 25 for a long time and is not used can be drained in time, the probability of breeding bacteria in the water tank 25 is reduced, the use safety of the user is further ensured, and the health of a human body is facilitated.

According to the control method of the air conditioner, in the process that the humidifying module does not work for a long time, when water is detected in the water tank 25, a user can be reminded to drain the water tank 25 or the submachine 20 automatically enters a drainage mode to drain the water in the water tank 25, so that the problem that the water in the water tank 25 is not used for a long time and is stored in the water tank 25 to cause bacteria breeding is solved, the use safety of the user is further ensured, and the control method of the air conditioner is beneficial to the health of the human body.

According to some embodiments of the invention, the alerting the user may comprise:

the slave machine 20 can send the prompt message to the mobile terminal;

the prompt information may be used to inquire whether the user drains automatically, if the user selects yes, the slave machine 20 is controlled to enter the drainage mode, if the user selects no, the water tank 25 is to be manually treated by the user, and for the manual treatment of the water tank 25 by the user, the above description may be referred to, and details are not repeated here.

Through sending the prompt message to mobile terminal, the user can receive the prompt message in time to can handle in time, thereby can realize that water tank 25 deposits for a long time and the water that does not use can in time discharge, reduce the probability that the interior foster bacterium of water tank 25.

According to some embodiments of the present invention, the controlling the sub-machine 20 to enter the drainage mode may include:

the submachine 20 is controlled to move to a set area, for example, the set area can be a position in a toilet and adjacent to a floor drain;

after the slave unit 20 moves to the setting area, the water tank 25 may be controlled to directly drain toward the outside of the slave unit 20, for example, the water in the water tank 25 may be drained to a position on the floor of a toilet and adjacent to a floor drain, and the water drained to the floor may be drained from the room through the floor drain. As to how to control the water tank 25 to be drained directly to the outside of the slave set 20, reference is made to the above description, which will not be described herein. By controlling the water tank 25 to drain directly towards the outside of the sub-machine 20, the drainage efficiency can be improved and the energy consumption can be saved to a certain extent, for example, without using a drain pump, the energy consumption can be significantly saved.

According to some embodiments of the present invention, the controlling the sub-machine 20 to enter the drainage mode may include:

controlling the water tank 25 to supply water to the humidifying assembly, for example, the water pump can be started, the water in the water tank 25 can be pumped out by the water pump and output to the wet membrane assembly of the humidifying assembly, the water can be sprayed onto the wet membrane assembly in a spraying mode, the water in the water tank 25 can also be pumped out and conveyed into a water tank formed in the humidifying bracket, the lower part of the wet membrane assembly can be immersed into the water in the water tank, the water in the water tank can wet the wet membrane assembly and can upwards spread to other parts of the wet membrane assembly, or the combination of wetting and spraying can be realized;

the sub-fan part 23 is opened, the rotating speed of the sub-fan part 23 is controlled to be larger than a first set rotating speed, the rotating speed of the sub-fan part 23 is enabled to be larger in a drainage mode, the sub-fan part 23 drives airflow to penetrate through the wet film assembly, the wet film assembly can be enabled to be faster to evaporate, water in the water tank 25 can be faster to consume, and therefore water drainage time in the water tank 25 can be shortened.

It should be explained that, when the sub-fan unit 23 includes a fan, the rotation speed of the fan is adjusted to be greater than the first set rotation speed; when the sub-fan unit 23 includes two or more fans, the rotation speed of each fan may be adjusted to be greater than the first set rotation speed.

Wherein, in the process of drainage, detect the water level in the water tank 25 in real time, when detecting that there is no water in the water tank 25, can control sub-fan part 23 and water pump to stop working, or can control the water pump to stop working and make sub-fan part 23 continue to operate and stop working after a period of time.

In a manner similar to humidification, in the drainage mode, the supply wet membrane module in the water tank 25 is evaporated, so that drainage of the water tank 25 is more convenient and is not limited by the position, and the submachine 20 can drain the water tank 25 in any position by adopting the drainage mode.

Alternatively, the rotation speed of the sub-fan unit 23 in the humidification mode is less than the first set rotation speed, and the time for discharging the water in the water tank 25 can be shortened by making the rotation speed of the sub-fan unit 23 in the humidification mode less than the rotation speed of the sub-fan unit 23 in the drainage mode, which makes the water in the water tank 25 consumed faster in the drainage mode relative to the water in the water tank 25 in the humidification mode. Further, the rotation speed of the water pump in the humidifying mode is also lower than that in the draining mode, so that more water is supplied to the wet membrane module in the water tank 25 per unit time, and the consumption in the water tank 25 is further increased in combination with the higher rotation speed of the sub-fan, and the draining time of the water in the water tank 25 is further shortened.

According to some alternative embodiments of the present invention, the controlling the rotation speed of the sub-fan unit 23 to be greater than the first set rotation speed may include:

whether a person is in the room or not can be identified through a camera arranged on the sub machine 20, and whether a person is in the room or not can be identified through a camera arranged on the main machine 10;

if the person is determined to be in the room after the identification, analysis and judgment, the rotating speed of the sub-fan component 23 can be controlled to be adjusted to a second set rotating speed, and the second set rotating speed is greater than the first set rotating speed;

if it is determined that no person is present in the room after the identification, analysis and determination, the rotation speed of the sub-fan unit 23 may be controlled to be adjusted to a third set rotation speed, and the third set rotation speed is greater than the second set rotation speed.

The rotating speed of the sub-fan part 23 is adjusted according to whether people are in the room, so that the rotating speed of the sub-fan part 23 is larger when no people are in the room compared with that when people are in the room, the evaporation efficiency of the wet film assembly can be further improved, the water in the water tank 25 can be consumed faster, the water discharge time of the water tank 25 can be further shortened, and larger noise generated by the sub-fan part 23 in high-speed operation cannot influence users; meanwhile, when people are in the room, the rotating speed of the sub-fan component 23 is lower than that of the sub-fan component when no people are in the room, noise generated when the sub-fan component 23 works can be reduced, and therefore influence on users can be reduced.

Alternatively, the third set rotational speed may be the highest rotational speed of the sub-fan unit 23, so that when no one is present indoors, the rotational speed of the sub-fan unit 23 may be operated at the highest rotational speed, the evaporation efficiency of the wet film assembly may be significantly improved, thereby allowing the water in the water tank 25 to be consumed more quickly, the water discharge time of the water tank 25 may be further shortened, and the loud noise generated by the sub-fan unit 23 operating at a high speed may not affect the user.

According to some optional embodiments of the present invention, the main unit 10 may include a fresh air module adapted to communicate with the sub-machine cavity 13, the fresh air module may include a fresh air pipe adapted to communicate with the sub-machine cavity 13, and the fresh air module may further include a valve for controlling the communication and isolation of the fresh air pipe with the sub-machine cavity 13. The fresh air module can also comprise a fresh air fan component, the fresh air fan component can be arranged in the submachine cavity 13 or in a fresh air pipe, the fresh air fan component can pump out air in the submachine cavity 13 to the outside or pump out outdoor air to the submachine cavity 13, and when the separation port 14 of the submachine cavity 13 is opened, the fresh air fan component can discharge indoor air to the outside and can also introduce outdoor air into the inside.

Wherein, the controlling the sub-machine 20 to enter the drainage mode may further include:

the humidity of the indoor environment is collected, the humidity of the indoor environment can be collected through a humidity sensor arranged on the submachine 20 or a humidity sensor arranged on the main machine 10, and whether the humidity of the indoor environment is greater than the set humidity or not is judged according to the collected result;

if the indoor environment humidity is higher than the set humidity, the indoor environment humidity is higher at the moment, and if the submachine 20 discharges the humidified airflow to the indoor in the drainage mode, the drainage efficiency is lower, the submachine 20 can be controlled to move into the submachine cavity 13 or be kept in the submachine cavity 13 at the moment, the submachine 20 can be controlled to move into the submachine cavity 13 when the submachine 20 is positioned outside the submachine cavity 13, the submachine 20 can be kept in the submachine cavity 13 when the submachine 20 is already positioned in the submachine cavity 13, and the fresh air module is controlled to work, so that outdoor air is introduced to accelerate evaporation of the wet film component or humid air discharged by the submachine 20 is extracted to the outdoor, the evaporation efficiency of the wet film component can be improved, and the drainage efficiency of the water tank 25 is higher under the condition of high indoor environment humidity;

if the indoor environment humidity is not greater than the set humidity, it is indicated that the indoor environment humidity is smaller at this moment, the air flow is discharged to the indoor after the humidification by the sub machine 20 in the drainage mode, the water tank 25 can be enabled to have higher drainage efficiency, at this moment, the sub machine 20 can be controlled to move out of the main machine 10 or be kept out of the main machine 10, when the sub machine 20 is located in the main machine 10, the sub machine 20 can be controlled to move out of the main machine 10 to the ground, when the sub machine 20 is already located out of the main machine 10, the sub machine 20 can be kept out of the main machine 10, so that the water in the water tank 25 can be timely discharged to prevent the bacteria from being grown in the water tank 25, meanwhile, the indoor air can be humidified, and the indoor environment comfort level is improved.

Alternatively, the set humidity may be not less than 40%, for example, the set humidity may be 50% -60%. In this way, when the indoor slow-falling humidity is low, the slave unit 20 can be in the water discharge mode, so that the slave unit 20 can discharge water in the water tank 25 to the indoor air in a manner similar to humidification, and the slave unit 20 has high water discharge efficiency. On the other hand, when the indoor humidity is high, the slave unit 20 is returned to the slave unit cavity 13 of the master unit 10, and in the drain mode, the wet air discharged from the slave unit 20 is directly discharged to the outside.

In some embodiments of the present invention, the controlling the operation of the fresh air module may include:

the fresh air module is controlled to discharge air in the sub-machine cavity 13 towards the outside, specifically, the fresh air machine component can be controlled to be opened, the sub-machine 20 is used for opening the sub-air machine component 23 and the water pump in the drainage mode, water in the water tank 25 is conveyed to the wet film component through the water pump, the sub-air machine component 23 drives the air in the sub-machine cavity 13 to enter the sub-machine 20 from the air inlet of the sub-machine 20, the air entering the sub-machine 20 penetrates through the wet film component and takes away moisture on the wet film component, the air humidified by the wet film component flows into the sub-machine cavity 13 through the air outlet of the sub-machine 20, the fresh air machine of the fresh air module pumps the air humidified in the sub-machine cavity 13 to the outside, and therefore the water in the water tank 25 can be discharged in a short time in a mode similar to humidifying the air under the condition that the indoor environment humidity is high.

It should be explained that although in this embodiment, the fresh air device draws out the air in the sub-machine cavity 13, the indoor air can enter the sub-machine cavity 13 through the gap or other channel on the main machine shell 11, so that the air in the sub-machine cavity 13 is drawn out again and simultaneously the indoor air is supplemented, and the pressure in the sub-machine cavity 13 is kept balanced with the external pressure.

In other specific embodiments of the present invention, the controlling the operation of the fresh air module may further include:

collecting and determining the outdoor temperature and the outdoor humidity, for example, collecting the outdoor temperature by a temperature sensor arranged on an air conditioner outdoor unit, and collecting the outdoor humidity by a temperature sensor arranged on the air conditioner outdoor unit, and when the outdoor temperature is not lower than the indoor temperature and the outdoor humidity is lower than the indoor humidity, introducing the outdoor air into the sub-machine cavity 13;

specifically, can control fresh air module's fresh air machine part and open, carry outdoor air in the sub-machine chamber 13 towards sub-machine chamber 13, introduce the outdoor air that external temperature is higher and humidity is lower in sub-machine chamber 13, high temperature drying air passes through in the sub-machine chamber 13 enters into sub-machine 20 through the air intake of sub-machine 20, can take away the moisture on the wet film assembly fast, the air after being humidified by the wet film assembly flows into sub-machine chamber 13 through the air outlet of sub-machine 20, can finally flow into indoorly through gap or other passageways etc. on the main casing body, thereby can be under the higher condition of indoor ambient humidity, realize discharging the water in the water tank 25 in short time through the mode similar to the humidification air.

In some optional embodiments of the present invention, if the indoor environment humidity is greater than the set humidity, the controlling the sub-machine 20 to move into the sub-machine cavity 13 or to be kept in the sub-machine cavity 13 may include:

collecting the distance between the user and the host 10;

the rotation speed of the sub-fan unit 23 and the rotation speed of the fresh air unit of the fresh air module can be controlled according to the distance between the user and the main unit 10. For example, the rotation speed of the sub-fan 23 may be in positive correlation with the distance between the user and the main machine 10, and the larger the distance between the user and the main machine 10 is, the larger the rotation speed of the sub-fan 23 is, and the smaller the distance between the user and the main machine 10 is, the smaller the rotation speed of the sub-fan 23 is. The rotating speed of the fresh air fan component can be positively correlated with the distance between the user and the host machine 10, the larger the distance between the user and the host machine 10 is, the larger the rotating speed of the fresh air fan component is, the smaller the distance between the user and the host machine 10 is, and the smaller the rotating speed of the fresh air fan component is. The rotating speed is adjusted according to the distance between a user and the main machine 10, so that the influence of noise generated by the work of the fan on the user can be reduced while high-efficiency drainage is realized.

In some embodiments of the present invention, if the indoor environment humidity is not greater than the set humidity, the controlling the sub-machine 20 to move to the outside of the main machine 10 or to be kept at the outside of the main machine 10 may further include:

controlling the sub-unit 20 to move away from the user allows the sub-unit 20 to be in the drain mode with a greater distance from the user, reducing the effect of noise generated during operation of the sub-unit 20 on the user, in which case the sub-fan unit 23 may operate at a higher speed.

According to some optional embodiments of the present invention, after controlling the sub-machine 20 to enter the drainage mode, the method may further include:

Optionally, the set time may be 5min to 30 min.

Alternatively, the rotation speed of the sub-fan unit 23 may be reduced to reduce the operating noise during the sub-fan unit 23 continues to operate for a set time after the water in the water tank 25 is discharged.
