In the embodiment of the disclosure, the intelligent home appliance refers to a home appliance formed after a microprocessor, a sensor technology and a network communication technology are introduced into the home appliance, and has the characteristics of intelligent control, intelligent sensing and intelligent application, the operation process of the intelligent home appliance often depends on the application and processing of modern technologies such as the internet of things, the internet and an electronic chip, for example, the intelligent home appliance can realize remote control and management of a user on the intelligent home appliance by connecting the electronic appliance.

The cross-flow fan used by the air conditioner comprises a plurality of sections of fan units, the sections of fan units are fixedly connected with the same rotating speed, and different air outlet modes can be switched only by adjusting the rotating speed of the motor. In order to further enrich the air outlet form of the cross-flow fan, a variable-speed air supply method, a variable-speed air supply device and an indoor unit are disclosed in the related art, and the fan of the indoor unit comprises a plurality of cross-flow fan blades capable of being controlled to rotate at different rotating speeds. Through the non-uniform air supply mode, a non-uniform air field is generated by one indoor unit or the air field which changes along with time is generated, so that different air outlet positions of the indoor unit correspond to different wind speeds or the wind speed ratio of each position changes along with time, and the air field is closer to natural wind. The indoor unit is beneficial to creating wind sensation close to natural wind for users and improving the use experience of the users.

The related art has a problem in that wind perceived by a user in a non-uniform wind field at various positions in the wind field is random or uniform, and a region where the user is located cannot be adjusted in a targeted manner. For example, the initial starting temperature of the air conditioner is unstable, and the user is uncomfortable when the air conditioner blows out air directly; the air speed of the air conditioner is reduced after the air conditioner operates for a period of time, the wind sense felt by a user is weaker, and the comfort is poor.

Implementation of the method provided by the embodiment of the disclosure is based on an air conditioner, wherein a cross-flow fan of the air conditioner comprises a plurality of fan units capable of being controlled to rotate independently. According to the method provided by the embodiment of the disclosure, the wind field of the air conditioner is divided into a plurality of air outlet areas corresponding to the multi-section cross-flow fans, and the operation of the multi-section cross-flow fans is controlled according to the position of the user, so that the air conditioner can form a non-uniform wind field based on the position of the user, and direct blowing prevention avoiding the position of the user or centralized air supply towards the position of the user is realized.

Specifically, referring to fig. 1-8, an embodiment of the present disclosure provides an air conditioner, including a housing 500 and a cross flow fan, where the housing is configured with a receiving space, and the cross flow fan is disposed in the receiving space. The cross-flow fan comprises a rotating shaft 100 and a plurality of fan units 200, wherein the fan units 200 are arranged along the length direction of the rotating shaft 100, and each fan unit 200 can independently and controllably rotate; the fan unit 200 includes a driving disc 210, a first coupling assembly 220, a wind wheel 230, and a second coupling assembly 240, wherein the driving disc 210 is disposed on the rotating shaft 100 and rotates synchronously with the rotating shaft 100; the first coupling assembly 220 is disposed on the driving disk 210; the wind wheel 230 is rotatably disposed on the rotating shaft 100 corresponding to the driving disc 210; the second coupling assembly 240 is disposed on the wind wheel 230, the first coupling assembly 220 and the second coupling assembly 240 can be controlled to switch between a coupling state and a separation state, the wind wheel 230 rotates with the driving disc 210 when the first coupling assembly 220 is coupled with the second coupling assembly 240, and the wind wheel 230 can rotate with respect to the driving disc 210 when the first coupling assembly 220 is separated from the second coupling assembly 240.

In the embodiment of the present disclosure, the cross flow fan includes one rotation shaft 100 and a plurality of fan units 200. The rotating shaft 100 is in driving connection with the fan motor and is rotatably arranged at a preset installation position. The fan unit 200 is cylindrical and its axis is collinear with the axis of the rotary shaft 100. The rotation shaft 100 penetrates the plurality of fan units 200, and on the one hand, serves to fix the plurality of fan units 200 and on the other hand, provides a driving force for rotation of the fan units 200.

The plurality of fan units 200 are arranged side by side and are combined in a multi-stage manner to serve as fans of the cross-flow fan. Each fan unit 200 is independently controllable to rotate, i.e., each fan unit 200 may be controllably selected to rotate with the rotational axis 100 or not rotate with the rotational axis 100. Illustratively, the plurality of fan units 200 are all rotated to achieve a larger air volume of the air outlet; the fan units 200 with odd serial numbers in the fan units 200 rotate to realize smaller air quantity of air outlet; the plurality of fan units 200 sequentially rotate for a preset period of time to realize a wind sweeping function.

If a separate output motor and a corresponding control module are provided for each fan unit, the cost of the cross flow fan is greatly increased and the structure of the cross flow fan is complicated. The cross-flow fan provided by the embodiment of the disclosure comprises a driving motor, wherein the driving motor is used for driving selected fan units or all fan units to rotate.

The driving of the plurality of fan units by one driving motor is realized based on the following structure. Taking a fan unit as an example, the fan unit 200 includes a drive plate 210 and a wind wheel 230. The driving disk 210 is concentric with the rotation shaft 100 and fixedly connected with the rotation shaft 100. The wind wheel 230 is rotatably disposed on the rotation shaft 100. Rotatable means that the wind wheel 230 can rotate relative to the rotation shaft 100. The drive plate 210 is provided with a first coupling assembly 220 and the wind wheel 230 is provided with a second coupling assembly 240. When the first coupling assembly 220 and the second coupling assembly 240 are in the coupled state, the driving disc 210 drives the wind wheel 230 to rotate when rotating, that is, the rotating shaft 100 indirectly drives the wind wheel 230 to rotate. When the first coupling assembly 220 and the second coupling assembly 240 are in the separated state, the wind wheel 230 does not rotate with the driving disc 210 or the rotating shaft 100. Due to the existence of friction force, a certain acting force can be still applied to the rotation of the wind wheel 230 when the rotation shaft 100 rotates, and at the moment, the wind wheel 230 rotates at a rotating speed far lower than the rotating speed of the rotation shaft 100, so that an actual wind outlet effect can not be achieved. The fact that the wind wheel 230 does not rotate with the rotating shaft 100 means that the rotation speed of the wind wheel 230 is far lower than the rotation speed of the rotating shaft 100, and even is zero. For the plurality of fan units 200, the selected one or more fan units 200 may be rotated by controlling the coupling states of the first coupling member 220 and the second coupling member 240 of the plurality of fan units 200, respectively.

By using the air conditioner provided by the embodiment of the disclosure, the cross-flow fan comprises a plurality of sections of spliced fan units 200, and each fan unit 200 is small in length, easy to take and put and not easy to deform in the use process; each fan unit 200 can be independently controlled to rotate, and the cross-flow fan can rotate by selecting one or more of the fan units 200 so as to realize different air outlet functions; the fan unit is selected without a connecting rod which moves axially, so that a movable space is not required to be reserved for the connecting rod, and the miniaturization of the cross-flow fan is facilitated.

Optionally, the first coupling component comprises a first magnetic component, and the second coupling component comprises a second magnetic component, and the first magnetic component generates magnetic attraction with the second magnetic component when energized.

The first magnetic component is an electromagnet, and the second magnetic component is a permanent magnet. And when the first magnetic component is electrified, magnetic attractive force is generated between the first magnetic component and the second magnetic component, and the first magnetic component and the second magnetic component realize magnetic coupling through the magnetic attractive force. As an implementation form, the rotation shaft is electrically connected with the sliding of the fixedly arranged power module through the electric brush, the rotation shaft is provided with an electrode contact, and the first magnetic component realizes power input and control through the electrode contact. Under the condition that the first coupling component rotates, the first magnetic component is electrified, the second magnetic component is pulled by electromagnetic force to gradually rotate synchronously with the first coupling component, and the coupling process is smooth and soft without mechanical friction. With such arrangement, it is convenient to switch the coupling state and the separation state between the first coupling member and the second coupling member.

Optionally, the driving disc 210 is provided with a pin hole along the radial direction, and the second coupling assembly 240 is provided with a driving groove; the first coupling assembly 220 includes a driving pin 221, the driving pin 221 is slidably disposed in the pin hole, the driving pin 221 extends into the driving slot when the first coupling assembly 220 is coupled with the second coupling assembly 240, and the driving pin 221 retracts from the driving slot when the first coupling assembly 220 is separated from the second coupling assembly 240.

In this case, the first coupling component 220 and the second coupling component 240 are in the form of a plug-in fit. Specifically, the first coupling assembly 220 includes a retractable driving pin 221, and the second coupling assembly 240 configures a driving groove to be matched with the driving pin 221. The drive pin 221 extends along a radial line of the drive disk 210 and the second coupling assembly 240 is located on the outer ring of the drive disk 210. The driving disk 210 is radially provided with pin holes for fixing the driving pins 221 and providing sliding rails for the extension and retraction of the driving pins 221. The opening size of the driving groove is matched with the size of the driving pin 221. When the driving pin 221 is extended, it is inserted into the driving groove of the second coupling member 240. At this time, the first coupling member 220 and the second coupling member 240 are in a coupled state, the driving disk 210 rotates, and a force perpendicular to the driving pin 221 is applied to the second coupling member 240 through the driving pin 221. The second coupling assembly 240 rotates and the rotary fan unit 200 rotates together with the driving disk 210. With such arrangement, when the first coupling assembly 220 and the second coupling assembly 240 are coupled, the connection structure is relatively firm, which is beneficial for the driving disk 210 to drive the fan unit 200 to rotate.

Alternatively, the driving groove has a guide section 251 and a catching section 252, the guide section 251 having an inclined surface, and the driving pin 221 being extended into the catching section 252 under the guide of the guide section 251.

When the rotation of the driving disk 210 is stopped, the driving disk 210 and the fan unit 200 cannot be stopped at the same relative position each time, and thus the driving pin 221 may not be extended into the driving groove when extended. In order to make the driving pin 221 accurately enter the driving groove after extending, the driving groove is divided into two sections from outside to inside along the radial line of the second coupling assembly 240, and a guiding section 251 and a clamping section 252 are sequentially arranged from outside to inside. The guide section 251 has a large opening and a sloping ramp along which the drive pin 221 can slide into the snap section 252 of the drive slot as soon as it enters the large opening of the guide section 251. The opening size of the clamping section 252 is matched with the size of the driving pin 221, and the driving pin 221 is clamped into the clamping section 252 to drive the fan unit 200 to rotate. As an implementation, the guide section 251 has a horn shape, and the larger end faces outwards and the smaller end is butted with the entrance of the clamping section 252. With such an arrangement, the engagement between the drive pin 221 and the drive groove can be made easier. The driving pin 221 is retracted during rotation of the fan unit 200 with the rotation shaft 100, and the fan unit 200 is directly driven to be disconnected from the driving disc 210; during the rotation of the rotation shaft 100 while the fan unit 200 is stopped, the driving pin 221 is extended, and the driving pin 221 is inserted into the catching section 252 of the driving groove under the guide of the guide section 251 of the driving groove, thereby driving the fan unit 200 to rotate. With such an arrangement, the engagement between the driving pin 221 and the driving groove can be facilitated, which is advantageous in switching the coupled state and the decoupled state of the first coupling member 220 and the second coupling member.

Optionally, the driving disc 210 is provided with a plurality of pin holes along a plurality of radial lines, and the first coupling assembly 220 includes a plurality of driving pins 221, where the plurality of driving pins 221 are slidably disposed in the plurality of pin holes in a one-to-one correspondence; the second coupling assembly 240 is provided with a plurality of driving grooves, which are matched with the driving pins 221 in a one-to-one correspondence.

The plurality of pin holes are distributed circumferentially around the drive disk 210, preferably in a uniform distribution, so that the rotation of the drive disk 210 is more balanced. Each of the plurality of pin bores is also oriented along a radial line of the drive disk 210. The first coupling assembly 220 includes a plurality of driving pins 221, and the driving pins 221 are in one-to-one correspondence with the pin holes. The second coupling assembly 240 is provided with a plurality of driving grooves, and the driving pins 221 are in one-to-one correspondence with the driving pins 221. With such an arrangement, on the one hand, the plurality of driving pins 221 and the plurality of driving slots cooperate to improve the coupling between the first coupling component 220 and the second coupling component 240 more stably and reliably; on the other hand, the driving disk 210 needs to be rotated only a small distance to allow the plurality of driving pins 221 to be inserted into the plurality of driving grooves.

Alternatively, the drive pin 221 is a magnetic drive pin 221; the drive disk 210 includes: an electromagnetic ring 211, a holding ring 212, and a connector 213, wherein the electromagnetic ring 211 is fixed to the rotation shaft 100, and the electromagnetic ring 211 is extended or retracted by a magnetic force driving the driving pin 221; a retaining ring 212 positioned on the outer ring of the electromagnetic ring 211, and a pin hole is formed on the retaining ring 212; and a connecting member 213 connected to the electromagnetic ring 211 and the holding ring 212 for fixedly connecting the electromagnetic ring 211 and the holding ring 212.

The drive disk 210 includes an inner ring electromagnetic ring 211 and an outer ring retaining ring 212, the electromagnetic ring 211 being concentric with the retaining ring 212. The driving disc 210 further includes a connection member 213, wherein the connection member 213 is used to connect the electromagnetic ring 211 and the retaining ring 212, and the connection member 213 includes a plurality of radial ribs, and two ends of each rib are connected to the electromagnetic ring 211 and the retaining ring 212, respectively. The driving pin 221 is a permanent magnet, the electromagnetic ring 211 is an electromagnet, and the electromagnetic ring 211 is used for generating magnetic attraction force to extend or retract the driving pin 221. The retaining ring 212 is provided with a plurality of pin holes as described above to mount a plurality of driving pins 221 and provide sliding tracks for the driving pins 221. The electromagnetic ring 211 plays a role of extending and retracting the driving pin 221 and also serves as a structural member of the driving disc 210, and the driving disc 210 is stable in structure and light in weight; the electromagnetic ring 211 drives the magnetic driving pin 221 to stretch and retract, so that the driving structure is simple and reliable.

Optionally, the cross flow fan further includes a switching device 300, where the switching device 300 is configured to switch the first coupling component 220 and the second coupling component 240 to a coupled state and a decoupled state; wherein the rotating shaft 100 is of a hollow structure; the switching device 300 comprises a fixed rod 310, a wire harness 320 and an electric brush 330, wherein the fixed rod 310 penetrates into the rotating shaft 100, and the rotating shaft 100 is provided with an electric brush groove corresponding to the electromagnetic ring 211 of the driving disc 210; a wire harness 320 fixed to the fixing rod 310; and a brush 330 having one end electrically connected to the wire harness 320 and the other end extending into the brush groove to electrically connect the wire harness 320 with the electromagnetic ring 211.

The switching device 300 is used for switching the coupled state and the decoupled state of the first coupling assembly 220 and the second coupling assembly 240 of the fan unit 200 so as to control the rotation of the fan unit 200. The rotation condition of the fan unit 200 includes a condition of rotating with the rotation shaft 100 and a condition of not rotating with the rotation shaft 100. Preferably, the switching device 300 corresponds to all of the fan units 200, which can facilitate the control of the cross flow fan to the fan units 200. The cross flow fans are individually controlled by the switching device 300 to realize different air outlet functions for each fan unit 200.

Specifically, the switching device 300 includes a fixed lever 310, a wire harness 320, and a brush 330. The rotating shaft 100 is a hollow rod, and the fixing rod 310, the wire harness 320 and the brush 330 are all located in the rotating shaft 100. The rotation shaft 100 is a moving part, the fixing lever 310 is a fixed part, and the fixing lever 310 is stationary when the rotation shaft 100 rotates. The fixing lever 310 is used to provide a mounting position for the wire harness 320 and the brush 330. The wire harness 320 has one end electrically connected to a power supply device such as a junction box and the other end connected to the brush 330. The rotating shaft 100 is provided with brush grooves corresponding to the brushes 330, and the brushes 330 pass through the brush grooves to be electrically connected with the electromagnetic ring 211.

With such arrangement, the electromagnetic ring 211 can be electrically connected well even when the rotation shaft 100 rotates, and the rotation of the single fan unit 200 can be controlled by controlling the on-off state and the current direction of the electromagnetic ring 211.

Alternatively, the fixing rod 310 is of a hollow structure, and the wire harness 320 penetrates into the fixing rod 310.

Each fan unit 200 of the plurality of fan units 200 requires a corresponding telephone and connection lines. In the case where the number of the fan units 200 is large, the penetration of the wire harness 320 into the fixing lever 310 may make the overall structure of the switching device 300 simple, and easy to install and maintain.

The second end cap 232 is concentric with the first end cap 231 and collectively holds a plurality of blades 233. When the wind wheel 230 rotates, the plurality of blades 233 drive the air to move. By adopting the arrangement mode, the structure of the cross-flow fan can be simplified.

Optionally, the cross-flow fan further includes a plurality of blocking plates 400, where the blocking plates 400 are disposed on the driving disk 210, and the blocking plates 400 are used to keep the fan units 200 at preset positions along the length direction of the rotating shaft 100.

The wind wheel 230 may rotate relative to the rotational shaft 100, which also results in possible axial movement of the wind wheel 230 along the rotational shaft 100. If the wind wheel 230 is shifted in position along the length of the rotation shaft 100, the driving pin 221 is not engaged with the driving groove. Therefore, the blocking piece 400 is provided corresponding to the end surface of the wind wheel 230, and the blocking piece 400 restricts the movement of the wind wheel 230 along the length direction of the rotation shaft 100, so that the wind wheel 230 can be maintained at a preset position. The number of wind wheels 230 is plural, and at least two baffle plates 400 are respectively arranged at two ends of the rotating shaft. As a preferred embodiment, a baffle 400 is disposed between each two adjacent wind turbines 230. This may better define the position of the rotor 230.

Optionally, a planar bearing is provided between the baffle 400 and the wind wheel 230.

In the case that the wind wheel 230 does not rotate along with the rotation shaft 100, the provision of the plane bearing can reduce the friction between the wind wheel 230 and the blocking piece 400, thereby making the control of the rotation of the fan unit 200 by the cross-flow fan clearer.

As shown in fig. 9, an embodiment of the present disclosure provides a method for controlling an air conditioner, which is applied to the air conditioner, and the method includes:

s100, the air conditioner acquires the user position.

S200, controlling the operation of the plurality of fan units according to the user position of the air conditioner.

In the embodiment of the disclosure, the acquired user position may be acquired through an image recognition unit of the air conditioner, may also be acquired through a human body sensor, or may be acquired from a server.

An air outlet of the air conditioner is transversely arranged, and the cross-flow fan is transversely arranged. The range covered by the air outlet of the air conditioner is divided into a plurality of air outlet areas corresponding to a plurality of fan units of the cross-flow fan. And the other fan units are second fan units. The air conditioner controls the operation of a plurality of fan units according to the user position, and the operation of the fan units at least comprises switching of a starting state and a stopping state. Controlling the operation of the plurality of fan units according to the user position may distinguish the operation of the first fan unit from the operation of the second fan unit. When the air conditioner air outlet is required to be prevented from directly blowing users, the first fan unit is closed, and the second fan unit is started; turning off the second fan unit when it is desired to increase the user's wind sensation activates the first fan unit. In addition, in the process of moving the user, the physical fan units corresponding to the first fan unit and the second fan unit are changed, and in the process of moving the user, the air conditioner can be still prevented from directly blowing the user or strengthening the wind sensation of the user, so that the following type anti-direct blowing or following type air supply is realized.

By adopting the method for controlling the air conditioner provided by the embodiment of the invention, the operation of the plurality of fan units is controlled according to the user position, and the non-uniform air outlet based on the user position can be formed in the air conditioner. In the initial starting stage of the air conditioner, the fan unit corresponding to the user position stops rotating, so that discomfort of the user caused by unstable temperature is avoided; after the indoor temperature is stable, the fan units corresponding to the positions of the users rotate, and the rest fans stop rotating, so that the wind sense of the users is enhanced. The direct blowing prevention or concentrated air supply to the user is realized through the non-uniform wind field, and the use experience of the user is improved.

Optionally, referring to fig. 10, another method for controlling an air conditioner is provided in an embodiment of the present disclosure, and is applied to the air conditioner, where the method includes:

s100, the air conditioner acquires the user position.

S210, starting the fan unit farthest from the user by the air conditioner after starting.

S220, starting all fan units in sequence from far to near according to the first time interval.

After the air conditioner is started, the cross-flow fan needs to be started to adjust the indoor temperature. After starting up, the air conditioner starts the fan unit furthest away first.

After the air conditioner is started, the temperature of the air blown out by the cross flow fan is unstable. Taking an air conditioner operation refrigeration mode as an example, when the air conditioner is just started, the temperature of air blown out by the cross-flow fan is higher and is close to the indoor temperature; with the operation of the compressor, the temperature of the indoor heat exchanger is gradually reduced, and the temperature of the air blown out by the cross-flow fan is lower. If the air-conditioning air is blown directly to the user at this time, the fluctuation of the air temperature felt by the user is large, which may cause discomfort to the user. Therefore, the fan unit farthest from the user is started first after the air conditioner is turned on. The fan unit is one or more of the second fan units. When the user position corresponds to the middle fan unit of the cross-flow fan, the fan unit farthest from the user is the fan units positioned at the two ends of the cross-flow fan; when the user position corresponds to the fan unit at the first end of the cross-flow fan, the fan unit furthest from the user is the fan unit at the second end of the cross-flow fan. Thus, in the period of unstable starting temperature of the air conditioner, the air outlet of the air conditioner avoids the user position. The indoor temperature is gradually reduced, and meanwhile discomfort of a user caused by direct blowing of air out of the air conditioner is avoided.

Along with the operation of the air conditioner, the refrigerant circulation becomes stable, and the air outlet temperature of the air conditioner is also stable. At this time, the rest fan units are started gradually according to the first time interval so as to adjust the indoor temperature to the set temperature as soon as possible. The sequence of the other fan units is that the fan units are started one by one from far to near. When the user position corresponds to the middle fan unit of the cross-flow fan, the rest fan units are sequentially started from two sides to the middle according to a first time interval; when the user position corresponds to the fan units at the first end of the cross-flow fan, the rest fan units are sequentially started from the second end to the first end of the cross-flow fan.

By adopting the method, on one hand, the discomfort of a user caused by unstable temperature of the air conditioner after the air conditioner is started can be avoided; on the other hand, the fan units are sequentially started from far to near, the wind felt by the user is changed from weak to strong, and the whole wind feel is softer. Therefore, the user experience of the air conditioner in a period of time after the air conditioner is started can be improved.

Optionally, in step S220, all fan units are started in sequence from far to near according to a first time interval, where the first time interval is determined according to a temperature difference between the set temperature and the indoor temperature.

If the temperature difference between the set temperature and the indoor temperature is large, the requirement for adjusting the indoor temperature is considered to be urgent, and all fan units should be started as soon as possible to adjust the indoor temperature as soon as possible, so that the first time interval is small; if the temperature difference between the set temperature and the indoor temperature is small, the need for adjusting the indoor temperature is not considered to be urgent, and at this time, all fan units can be started up gently to reduce the discomfort of the straight-face air outlet, so the first time interval is large. This allows for more accurate control of the activation of the plurality of fan units.

Optionally, when the temperature difference between the set temperature and the indoor temperature is greater than or equal to 5 ℃, the first time interval is 30 seconds; when the temperature difference between the set temperature and the indoor temperature is less than 5 ℃, the first time interval is 1 minute.

Therefore, the time required by starting all the fan units is matched with the refrigerating and heating requirements of users, discomfort of the users caused by unstable temperature is relieved, the starting speed of all the fan units is increased, and the refrigerating and heating speeds of the air conditioner are further increased.

Optionally, referring to fig. 11, an embodiment of the present disclosure provides another method for controlling an air conditioner, which is applied to the air conditioner, and the method includes:

S100, the air conditioner acquires the user position.

S210, starting the fan unit farthest from the user by the air conditioner after starting.

S220, starting all fan units in sequence from far to near according to the first time interval.

S230, the air conditioner acquires the starting time.

S240, starting one or more fan units nearest to a user and turning off the rest fan units under the condition that the starting time is longer than or equal to the first time.

The air conditioner obtains the starting time, and the temperature difference between the indoor temperature and the set temperature and the change of the refrigerating capacity of the air conditioner are determined through the starting time. Illustratively, the first duration is 15 minutes, and after the air conditioner is turned on and operated for 15 minutes, the indoor temperature is considered to be close to the set temperature, and the cooling capacity of the air conditioner is reduced. The air outlet volume of the air conditioner is also reduced in correspondence with the cooling capacity of the air conditioner. As the air output decreases, the temperature of the user in the air field of the air conditioner increases. In order to avoid user discomfort caused by the reduction of the air output, after the refrigerating capacity of the air conditioner is reduced, only the first fan unit is kept on in the plurality of fan units, and the rest of the second fan units are closed. The first fan unit is one or more fan units nearest to the user, and the second fan unit is a fan unit other than the first fan unit. As the number of fan units rotating in the cross-flow fan is reduced, the air outlet range of the air conditioner is reduced, and the air outlet area corresponding to the user position has less or no change in wind speed.

By adopting the method, the discomfort of a user caused by the reduced wind speed of the air conditioner after the air conditioner operates for a period of time can be effectively avoided.

Optionally, the activating one or more fan units closest to the user in step S240 includes:

s241, the air conditioner acquires the number of users.

S242, determining the first number of the started fan units according to the number of the users.

S243, the air conditioner starts a first number of fan units nearest to the user' S location.

The acquired user position may be acquired by an image recognition unit of the air conditioner, or may be acquired by a human body sensor, or may be acquired from a server. In the case of a smaller number of users, the number of fan units to be turned on is also smaller. In the case of only one user, for example, the user can be covered in all directions by switching on only one or two fan units. In the case of a large number of users, the number of fan units to be turned on is also large. Illustratively, if the number of users is two, the air conditioner activates four fan units nearest to the user's location. The first number of the started fan units is determined according to the number of users, so that the discomfort of partial users caused by more users and less air output can be avoided.

By adopting the method, the number of the opened fan units can be matched with the number of users, so that the comfort of all users is improved.

Optionally, step S242 includes determining, according to the number of users, a first number of fan units to be turned on by the air conditioner: if the number of users is greater than or equal to the first number of people, the first number of fan units are all fan units; the first number is positively correlated with the first number of people if the number of users is less than the first number of people.

When the number of users is greater than or equal to the first number of people, the distribution of users is more dispersed, and the positions are relatively unfixed. And when the number of users is greater than or equal to the first number of people, the first number of fan units are all fan units, and the air conditioner starts all fan units. Therefore, all positions in the wind field of the air conditioner can have flowing air, and the comfortable experience of all users is improved. When the number of users is smaller than the first number of people, the users are fewer and the locations are relatively concentrated. At this time, the first number is positively correlated with the first number, and the smaller the first number is, the more concentrated the air supply is, so that the concentration degree of the air supply can be improved for fewer users, and the comfortable experience of the users is improved.

Optionally, as shown in conjunction with fig. 12, another method for controlling an air conditioner is provided according to an embodiment of the present disclosure, including:

s01, an air conditioner acquires an air supply mode;

s02, the air conditioner acquires the user position and controls the operation of the fan units according to the user position when the air supply mode is the automatic air supply mode.

S03, when the air supply mode of the air conditioner is the gradual change air supply mode, the air conditioner sequentially starts a plurality of fan units according to a second time interval in a single period and enables each fan unit to rotate for a second duration.

The air supply mode of the air conditioner can be set by a remote controller or a remote terminal, or can be set automatically according to a preset program. The air supply mode of the air conditioner at least comprises an automatic air supply mode and a gradual change air supply mode. In the automatic air supply mode, the air conditioner acquires a user position and controls the operation of the plurality of fan units according to the user position. That is, when the air-blowing mode of the air conditioner is the automatic air-blowing mode, the above-described S100 air conditioner acquires the user position, and S200 controls the operation of the plurality of fan units according to the user position. This allows the air conditioner to form a non-uniform wind field based on the location of the user. In the initial starting stage of the air conditioner, the fan unit corresponding to the user position stops rotating, so that discomfort of the user caused by unstable temperature is avoided; after the indoor temperature is stable, the fan units corresponding to the positions of the users rotate, and the rest fans stop rotating, so that the wind sense of the users is enhanced. The direct blowing prevention or concentrated air supply to the user is realized through the non-uniform wind field, and the use experience of the user is improved.

In the case where the air supply mode of the air conditioner is the progressive air supply mode, the air conditioner periodically controls the operation of the plurality of fan units, or the operation of the plurality of fan units is periodic. In a single cycle, a plurality of fan units are turned on at second intervals and rotated for second durations, respectively. For example, there are 5 fan units, the second time interval is 1 minute and the second time period is 1 minute. In this case a plurality of fan units rotate in a relay fashion, one fan unit at each instant. Still another example, the second time interval is 1 minute and the second duration is 2 minutes. In this case there are two fan units rotating at each moment. When a user is at a certain position, the air quantity sensed when the fan unit closest to the user position is started is larger, and the air quantity sensed when the fan unit farthest from the user position is started is smallest. With the start and stop of different fan units, the air quantity sensed by the user is non-uniform air outlet which changes along with time. By adopting the arrangement form, the air outlet quantity of the air conditioner can be adjusted by the quantity of the rotating fans, and the gradual change effect is realized by switching the rotating fan units.

Optionally, turning on the plurality of fan units in sequence and rotating each fan unit for a second period of time in step S03 includes: sequentially starting a plurality of fan units from one end to the other end, and sequentially closing the plurality of fan units from one end to the other end after a second time period; or sequentially starting the plurality of fan units from the middle to the two sides, and sequentially closing the plurality of fan units from the middle to the two sides after the second time period; or sequentially starting the fan units from two sides to the middle, and sequentially closing the fan units from two sides to the middle after the second time period.

The cross-flow fan is transversely arranged, a plurality of fan units are sequentially started from a first end to a second end, the fan units are closed from the first end to the second end after a second time period, and wind sweeps from the first end to the second end when seen from the right front of the air conditioner; similarly, the plurality of fan units are sequentially turned on from the middle to the two sides, and the plurality of fan units are sequentially turned off from the middle to the two sides after the second time period, and wind sweeps from the middle to the two sides when seen from the right front of the air conditioner; after the plurality of fan units are sequentially turned on from both sides to the middle, the plurality of fan units are sequentially turned off from both sides to the middle after a second period of time, and wind sweeps from both sides to the middle when seen from the right front of the air conditioner. By adopting the mode that the plurality of fan units are sequentially opened and closed according to a certain sequence, the air conditioner achieves the effect of sweeping wind while gradually changing the wind.

By adopting the method, the air outlet form of the air conditioner can be more diversified, so that different air outlet demands of various forms of users can be met.
