Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

A control method of an air conditioner according to an embodiment of the present invention is described below with reference to fig. 1 to 8.

As shown in fig. 1 to 3, the method for controlling an air conditioner according to the embodiment of the first aspect of the present invention, wherein the air conditioner may include a master unit 10 and a slave unit 20, and the slave unit 20 may be detachably mounted to the master unit 10. For example, the slave unit 20 may be detachably connected to the master unit 10, and when the slave unit 20 needs to be separated from the master unit 10, the slave unit 20 is detached from the master unit 10; when the slave unit 20 needs to be stored, the slave unit 20 can be attached to the master unit 10. When the slave unit 20 is attached to the master unit 10, the slave unit 20 may be attached to the outside of the master unit 10, or the slave unit 20 may be attached to the inside of the master unit 10.

For example, a mounting cavity 13 for mounting and accommodating the slave unit 20 may be formed in the main unit 10, the slave unit 20 may be mounted in the mounting cavity 13, a separation opening 14 may be formed at one side of the mounting cavity 13, and the slave unit 20 may be mounted in the main unit 10 or removed from the main unit 10 through the separation opening 14 to be separated from the main unit 10. Wherein, a separation door 15 for opening and closing the separation port 14 can be arranged at the separation port 14, the separation door 15 can be detachably mounted at the separation port 14, and when the separation door 15 is detached from the separation port 14, the separation door 15 opens the separation port 14; when the separation door 15 is attached to the separation port 14, the separation door 15 closes the separation port 14. The separation door 15 may be rotatably mounted to the separation opening 14, and the separation door 15 opens and closes the separation opening 14 by rotation of the separation door 15.

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.

Alternatively, the mounting cavity 13 and the accommodating cavity may be defined in the main chassis 11, and the mounting cavity 13 and the accommodating cavity may be separated, for example, a partition may be provided in the main chassis 11 to separate the space in the main chassis 11 into the mounting cavity 13 and the accommodating cavity. Wherein, the heat exchange air supply unit can be arranged in the containing cavity, and the submachine 20 can be installed in the installation 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 conditioner indoor unit 100 includes the main unit 10 and the sub unit 20, wherein a receiving cavity and a mounting cavity 13 which are arranged at an interval from top to bottom are defined in the main casing 11 of the main unit 10, the mounting cavity 13 is located below the receiving cavity, the heat exchange air supply unit is mounted in the receiving cavity, and the sub unit 20 can be mounted in the mounting cavity 13. Thus, the mounting cavity 13 for accommodating the sub-unit 20 is arranged at a lower position, so that the sub-unit 20 can be conveniently separated from the main unit 10 or mounted in the main unit 10.

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. Further, the air supply processing unit may further include at least one of a humidification module and a purification module, so that the sub-unit 20 has at least one of humidification and purification functions, and thus, the indoor air can be humidified and/or purified, 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 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 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 strengthened, 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 submachine 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 strengthened, 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.

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

the host 10 is controlled to be turned on and operated, for example, the host 10 can be controlled to perform heating operation or cooling operation, so that the indoor environment temperature can be adjusted;

control submachine 20 towards user's air supply and around the user removal, through controlling submachine 20 towards user's air supply, can the regional temperature in quick adjustment user position, and move around host computer 10 through submachine 20, can make submachine 20 supply air towards user's different health positions, can make the temperature of user's different positions all can obtain quick adjustment (promote near regional temperature of user fast when heating, reduce near regional temperature of user's body surface temperature and user fast when refrigeration), and can avoid the uncomfortable sense that the same health position air supply of long-time orientation user caused, thereby promote user's comfort level of blowing.

The slave unit 20 moves around the user, and the movement trajectory of the slave unit 20 may be a curved line or a straight line as long as the slave unit 20 moves around the outer periphery of the user. For example, the slave unit 20 may move around the user by using a circle or an arc having a radius equal to the distance from the user to the slave unit 20 as the center of the movement trajectory.

In the process of moving the slave unit 20 around the user, the slave unit 20 can reciprocate between the first position and the second position. For example, the sub-unit 20 linearly reciprocates between a first position and a second position; or the submachine 20 performs reciprocating arc movement between the first position and the second position; alternatively, the first and second positions may coincide and the handset 20 is reciprocating in a circular motion around the user. While the slave unit 20 is moving, the slave unit 20 always blows air toward the user.

Optionally, after the sub-machine 20 is moved to the area around the user, the sub-machine 20 is controlled to supply air to the user and move around the user, so that the sub-machine 20 can be located near the user, the air blown by the sub-machine 20 towards the user can be ensured to reach the user, and the air flow loss can be reduced due to the short air supply distance, so that the temperature of the area where the user is located can be adjusted better and faster. Moreover, because the sub-machine 20 moves to the area around the user and then blows air towards the user and moves around the user, the sub-machine 20 can move around the user by a larger circumferential angle, for example, the circumferential angle of the sub-machine 20 moving around the user can reach 360 degrees, so that the user can obtain a wind sensation in all directions, and the blowing comfort and the blowing feeling of the user are improved.

It should be explained that the circumferential angle of the movement of the sub-set 20 around the user is the circumferential angle of the movement of the sub-set 20 around the user when the sub-set 20 moves from the first position to the second position. Specifically, when the sub-machine 20 is at the first position, the connection line between the sub-machine 20 and the user is a first position connection line, when the sub-machine 20 is at the second position, the connection line between the sub-machine 20 and the user is a second position connection line, and the included angle between the second position connection line and the first position connection line is the circumferential angle of the sub-machine 20 moving around the user.

Alternatively, the range of the circumferential angle of the sub-machine 20 moving around the user may be 15-360 °, which may make different parts of the user's body feel a blowing sensation and also may make the temperature of different parts of the user's body quickly adjusted.

Optionally, the sub-unit 20 may also be moved into the air supply range of the main unit 10, so that the sub-unit 20 may relay the heat/cold of the main unit 10 to deliver the heat/cold to the user, thereby quickly adjusting the body surface temperature of the user and the temperature of the area near the user, quickly adjusting the temperature of the area around the user to a more comfortable temperature range, improving the comfort of the air conditioner, and meeting more and higher requirements of the user. When the sub-machine 20 moves to the air supply range of the main machine 10 to supply air to the user, the sub-machine 20 can move around the user in the air supply range of the main machine 10, so that the sub-machine 20 can always relay the heat/cold of the main machine 10 and convey the heat/cold to the user in the air supply process of the sub-machine 20 towards the user.

The controlling the slave unit 20 to move to the air blowing range of the master unit 10 may include:

in the process of moving the slave unit 20, the air inlet position of the slave unit 20 can be detected in real time, and whether the slave unit 20 moves into the air supply range of the master unit 10 is determined according to whether the air inlet position of the slave unit 20 is within the air supply range of the master unit 10. When the air inlet position of the slave unit 20 is determined to be within the air supply range of the master unit 10, the slave unit 20 may be controlled to stop moving, so that the slave unit 20 moves and stays within the air supply range of the master unit 10. The air inlet position of the submachine 20 is determined in the air supply range of the main machine 10 as a basis for determining the air supply range of the submachine 20 moving to the main machine 10, so that when the submachine 20 is in the air supply range of the main machine 10, the air inlet area of the submachine 20 can be positioned in the air supply range of the main machine 10, hot air/cold air sent out by the main machine 10 can enter the submachine 20 through the air inlet to be accelerated and then is conveyed towards a user through the air outlet of the submachine 20 by the submachine 20, the submachine 20 can better relay the heat/cold energy of the main machine 10, more heat/cold energy can be conveyed to the user, and the body surface temperature of the user and the temperature of the area near the user can be quickly adjusted.

Alternatively, the sub-machine 20 may be controlled to move to a position near the air supply range of the main machine 10 or within the air supply range of the main machine 10, and in the process that the sub-machine 20 supplies air to the user and moves around the user, the sub-machine 20 may pass through the air supply range of the main machine 10, so that the sub-machine 20 may convey cold air/hot air output by the main machine 10 toward the user, and the sub-machine 20 may convey air flow in a region outside the air supply range of the main machine 10 to the user, so that the user may feel different temperatures, and dynamic air supply is achieved.

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 and a handset main body provided on the base, the handset main body includes the above-mentioned air supply processing unit, the bottom of the base may be provided with wheels 22 to realize movement of the handset 20, the handset main body may rotate relative to the base, and the handset 20 may include a driving mechanism for driving the handset main body to rotate relative to the base. The rotation axis of the sub-machine main body can extend along the vertical direction, the sub-machine main body can rotate 360 degrees relative to the base, therefore, no matter the user is in any indoor position or any direction, the sub-machine 20 can control the driving mechanism to drive the sub-machine main body to rotate to enable the air outlet of the sub-machine 20 to face the user according to the specific direction of the user relative to the sub-machine 20, and therefore the adjustment and the change of the air outlet direction of the sub-machine 20 in the horizontal direction are conveniently achieved.

Optionally, during the operation of the air conditioner, the humidity judgment can be added to cooperate with the operation. For example, a humidity sensor may be disposed on the sub-machine 20 or the main machine 10, and the humidity sensor detects the indoor environment humidity, so that when the indoor environment humidity is lower than the preset humidity, the humidifying module of the sub-machine 20 may be opened to humidify the indoor environment, thereby improving the comfort level.

According to the control method of the air conditioner, after the main machine 10 operates to refrigerate/heat, air is supplied to the user through the sub-machine 20, the temperature of the area where the user is located can be quickly adjusted, the sub-machine 20 rotates around the main machine 10, air can be supplied to different body parts of the user through the sub-machine 20, the temperatures of the different body parts of the user can be quickly adjusted, discomfort caused by long-time air supply to the same body part of the user can be avoided, and therefore the air blowing comfort level of the user is improved.

According to some embodiments of the present invention, referring to fig. 6 to 8, controlling the sub-unit 20 to blow air toward and move around the user when the air conditioner is in a cooling operation may include:

the body surface temperature of the user can be collected through an infrared temperature sensor arranged on the sub machine 20 or an infrared temperature sensor arranged on the main machine 10, for example, in the embodiment of supplying air to the user after the sub machine 20 moves to the area around the user, the infrared temperature sensor arranged on the sub machine 20 can be used for collecting the body surface temperature of the user;

determining an area with the body surface temperature higher than the set temperature of the user, and indicating that the body surface temperature of the area of the user is too high and needs to be blown intensively for heat dissipation;

the air supply of the sub machine 20 is controlled to be carried out for a first preset time when the air supply is carried out towards the area where the body surface temperature of the user is higher than the set temperature, the sub machine 20 is controlled to stop moving within the first preset time, the air supply is carried out for the first preset time when the air supply is carried out towards the area where the body surface temperature of the user is higher than the set temperature through the sub machine 20, the air supply can be intensively carried out for the area where the body surface temperature of the user is higher than the set temperature, the area where the body surface temperature of the user is higher than the set temperature is rapidly cooled, and after the air supply is carried out for the first preset time when the air supply is carried out towards the area where the body surface temperature of the user is higher than the set temperature through the sub machine 20, the sub machine 20 continues to move around the user. Therefore, different body parts of the user can be cooled by blowing, the higher area of the body surface of the user can be cooled by blowing in a concentrated mode, the comfortable sensation is further improved, and the higher requirements of the user are met.

Alternatively, the first preset time may be 30s-300 s.

Optionally, the first preset time may be determined according to a temperature of an area where the body surface temperature of the user is higher than the set temperature, the first preset time may be in positive correlation with the temperature of the area where the body surface temperature of the user is higher than the set temperature, and the higher the temperature of the area where the body surface temperature of the user is higher than the set temperature, the longer the first preset time.

According to some embodiments of the present invention, controlling the sub-phone 20 to blow air towards and move around the user may include:

while the slave unit 20 moves around the user, the rotation speed of the slave unit 20 is gradually adjusted. Thus, the user can feel different wind speeds, and dynamic air supply of the slave unit 20 is realized. For example, while the slave unit 20 moves around the user, the rotation speed of the slave unit 20 may be gradually increased by a certain ratio so that the user can adapt to a large wind speed slowly, and after the wind speed of the slave unit 20 reaches a stable wind speed (for example, the stable wind speed may be an initial wind speed described below), the slave unit 20 may blow air to the user at the stable wind speed, so that the temperature in the area near the user can be adjusted quickly. After the body surface temperature of the user is adjusted to the preset comfortable temperature or after the temperature of the area around the user is adjusted to the comfortable temperature, the rotating speed of the submachine 20 can be reduced, and in the process of reducing the rotating speed of the submachine 20, the rotating speed of the submachine 20 can be gradually reduced according to a certain proportion, so that the user can slowly adapt to the change process of the rotating speed of the submachine 20, and the comfortable feeling of blowing of the user is further improved.

According to some embodiments of the present invention, referring to fig. 6-8, controlling the handset 20 to blow air towards the user comprises:

the spatial position of the user is collected and determined, the spatial position of the user can be collected and determined through an infrared camera on the submachine 20, and the spatial position of the user is determined, mainly the body posture of the user is determined, for example, whether the user is in a sitting posture or a standing posture, in addition, the heights of the users are different, for example, the difference between the heights of adults and children is large, and the spatial positions of the users are also different;

the air supply angle of the slave unit 20 is determined according to the spatial position of the user, and when the spatial position of the user is different, the air supply angle of the slave unit 20 in the vertical direction is different, for example, when the user is standing and when the user is sitting, the air supply direction of the slave unit 20 is different and is more inclined upward.

Alternatively, the air supply angle of the sub-machine 20 may be adjusted by an air deflector provided at the air outlet of the sub-machine 20, and the air supply angle adjustment in the up-down direction is realized by the up-down swing of the air deflector.

In some optional embodiments of the present invention, controlling the sub-unit 20 to supply air to the user during the cooling operation of the air conditioner may include:

the sequence of the air supply from the slave unit 20 to the user is: the air supply time of the head, the upper limbs and the lower limbs accounts for 4: 3: 2. among the different parts of the body, the head is most concentrated and most heated, and is most sensitive to the sensation of heat, while the upper limbs are more heated than the lower limbs. According to the different position heats of health and the impression is different like this, successively blow to human head, upper limbs, low limbs in proper order, and also reduce the time of blowing to head, upper limbs, low limbs in proper order, can make the position that human heat is concentrated relatively obtain the priority and blow and obtain more heat dissipation time of blowing more to can further promote the user comfort of blowing.

For example, when the sub-machine 20 blows air toward the head of the human body, the air blowing angle of the sub-machine 20 can be adjusted, for example, the air deflector can be adjusted, so that the sub-machine 20 blows air toward the head for a first set time, the head can dissipate heat quickly in time, and the comfort is improved. In the process of blowing air to the head by the submachine 20, the submachine 20 can move around the user, and in the process of moving the submachine 20, if an area with the body surface temperature higher than the set temperature of the user is collected, the submachine 20 can directionally blow air to the area for a first preset time, wherein the first preset time is less than the first preset time.

After the air blowing angle of the sub-machine 20 is adjusted after the sub-machine 20 blows air towards the head of the user for the first set time, for example, the air deflector can be adjusted, so that the sub-machine 20 blows air towards the upper limbs of the human body for the second set time, the upper limbs of the human body can be quickly cooled in time, and the comfort is improved. In the process of blowing air towards the upper limbs by the submachine 20, the submachine 20 can move around the user, and in the process of moving the submachine 20, if an area with the body surface temperature higher than the set temperature of the user is collected, the submachine 20 can directionally blow air towards the area for a first preset time, wherein the first preset time is less than the second preset time.

After the air supply of the sub-machine 20 is performed for the second set time toward the upper limbs of the user, the air supply angle of the sub-machine 20 is adjusted, for example, the air deflector is adjusted, so that the sub-machine 20 performs air supply for the third set time toward the lower limbs of the human body, the lower limbs of the human body can dissipate heat quickly in time, and the comfort is improved. In the process of blowing air towards the lower limbs by the submachine 20, the submachine 20 can move around the user, and in the process of moving the submachine 20, if the collected body surface temperature of the user is higher than the set temperature, the submachine 20 can directionally blow air towards the area for a first preset time, wherein the first preset time is less than a third preset time.

Wherein, the ratio of the first set time, the second set time and the third set time may be 4: 3: 2.

alternatively, when the slave unit 20 blows air to different body parts of the human body (for example, the head, the upper limbs, and the lower limbs described above), the first preset time for the slave unit 20 to blow air directionally to the region where the body surface temperature of the user is higher than the set temperature may be different, and the first preset time may be determined according to the temperature of the region where the body surface temperature of the user is higher than the set temperature.

According to some embodiments of the present invention, referring to fig. 6 to 8, controlling the sub-unit 20 to blow air toward the user location when the air conditioner is in the cooling operation may further include:

after the air supply of the submachine 20 to the user is carried out, timing the air supply time of the submachine 20 to the user, acquiring the body surface temperature of the user after the air supply of the submachine 20 to the user reaches a second preset time, and acquiring the body surface temperature condition of the user by acquiring the body surface temperature of the user;

when the body surface temperature of the user is determined to be higher than the preset comfortable temperature, the body surface temperature of the user is still higher, the submachine 20 keeps the current rotating speed to supply air to the user, and the body surface temperature of the user is further reduced rapidly;

when confirming that the user body surface temperature is not higher than the preset comfortable temperature, it is shown that the user body surface temperature reaches the comfortable temperature at this moment, the submachine 20 can be controlled to reduce the rotating speed, and the comfortable sensation is improved.

Alternatively, the step of controlling the slave unit 20 to reduce the rotation speed may include:

collecting the indoor environment temperature, for example, the return air temperature of the host 10 can be collected as the indoor environment temperature by a temperature sensor arranged at the return air inlet 111 of the host 10;

in the process that the submachine 20 supplies air to the user, the submachine 20 can detect the body surface temperature of the user through an infrared temperature sensor arranged on the submachine 20 and calculate the change speed of the body surface temperature of the user;

according to the change speed of the indoor environment temperature and the body surface temperature of the user, the speed reduction amplitude of the submachine 20 is determined, so that the rotating speed reduction amplitude of the submachine 20 is reasonable, and the comfort of the user is better.

For example, when the air conditioner operates in a cooling mode, when the indoor environment temperature is high and the change speed of the user body surface temperature is low, it indicates that the whole indoor environment temperature is still high at this time, and the deceleration amplitude of the submachine 20 is low, so that the user body surface temperature can be well maintained to be not higher than the preset comfortable temperature; when the indoor temperature is lower and the change speed of the body surface temperature of the user is larger, it is described that the whole indoor environment temperature is lower at this moment, the indoor environment temperature reaches a more comfortable temperature, and the deceleration amplitude of the submachine 20 is larger, so that the body surface temperature of the user can be better maintained to be not higher than the preset comfortable temperature, and the discomfort caused by the larger wind speed can be avoided.

In other embodiments, the rotation speed of the slave unit 20 may be corrected by means of voice/app or the like according to the voice feedback or the mobile phone feedback of the user while the slave unit 20 blows air to the user.

In other embodiments, the position of the slave unit 20 may be controlled by means of voice/app, for example, to control the slave unit 20 to move into the blowing range of the master unit 10 or to the area around the user.

According to some embodiments of the present invention, referring to fig. 7, before controlling the sub-phone 20 to blow air toward and move around the user, the method includes:

after the host 10 is turned on, the sub machine 20 is controlled to automatically move, the sub machine 20 is controlled to move to a region around a user, and the sub machine 20 stops moving after moving to the region around the user, wherein the sub machine 20 moves to the region around the user after the host 10 is turned on, or the sub machine 20 moves to the region around the user after the host 10 performs heating operation or cooling operation for a period of time, the user position can be acquired through the host 10 or the sub machine 20, for example, the user position can be acquired through an infrared camera on the host 10 or the sub machine 20, and the sub machine 20 can automatically move to the region around the user according to the user position; of course, when the slave unit 20 is already in the area around the user, the slave unit 20 may remain stationary;

the slave unit 20 can automatically move to the area around the user according to the user position. Therefore, the sub machine 20 can supply air towards the user in a short distance, and the air blown out by the sub machine 20 can reach the position of the user, so that the adjusting efficiency of the temperature of the area near the user can be ensured. Moreover, through the operation of the sub-machine 20, the airflow flow of the area around the user can be enhanced, the airflow on the upper layer is attracted to move downwards by combining the air inlet negative pressure of the sub-machine 20, the temperature migration of the area around the sub-machine 20 is realized, the low temperature of the area around the user can quickly reach a more comfortable temperature, and the use comfort of the air conditioner is further improved.

For example, when the air conditioner is operated to heat, after the sub-machine 20 moves to the area around the user, when the sub-machine 20 is operated, the hot air flow rises under the action of the gravity of the sub-machine 20, the sub-machine 20 can convey the air flow with lower temperature at the lower part to the higher part, so as to realize air disturbance, and the air flow with lower temperature at the lower part moves upwards, so that the air temperature at the higher part is relatively reduced, and 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.

For example, when the air conditioner operates in a cooling mode, after the submachine 20 moves to the area around the user, when the submachine 20 operates, the cold air flow falls under the action of the gravity of the submachine 20, 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 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 position near the user, the temperature of the air near the user from top to bottom is integrally uniform, and the comfort is improved.

Alternatively, the "user peripheral area" may be determined according to a negative pressure area formed when the sub-machine 20 operates, a negative pressure area may be formed near the air inlet of the sub-machine 20 when the sub-machine 20 operates, and when the sub-machine 20 is located in the user peripheral area, the size of the user peripheral area may be determined according to the size of the negative pressure area formed when the sub-machine 20 operates, so that the user may be located or located near the negative pressure area of the sub-machine 20. Thus, when the sub-unit 20 is in operation, the sub-unit 20 can enhance the airflow flowing in the area around the user, thereby facilitating the rapid adjustment of the temperature in the area around the user, and the rapid adjustment of the temperature in the area around the user to a more comfortable temperature range, especially the adjustment of the temperature at the lower part of the area around the user to a comfortable temperature range.

Optionally, the "area around the user" may be located in a range area with a radius a and a center of the user, where a is 1-2 m. This may allow a user to be located or near the handset 20. Thus, when the sub-machine 20 works, the sub-machine 20 can enhance the airflow flow of the area around the user, thereby being beneficial to quickly adjusting the temperature of the area around the user, so that the temperature of the area around the user can be quickly adjusted to be in a more comfortable temperature range, and particularly, the temperature at the lower part of the area around the user can be adjusted to be in a comfortable temperature range; further, the user can be prevented from feeling uncomfortable due to the proximity of the slave unit 20 to the user. Further, a ranges from 1.5m to 2m, for example, a can be 1.5m, 1.8m, 2m, and the like.

For example, in some embodiments of the present invention, the size of the negative pressure region formed when the sub-machine 20 rotates at the highest speed is used as the size of the region around the user, for example, when the sub-machine 20 rotates at the highest speed, a negative pressure region with a distance a from the sub-machine 20 is formed near the air inlet of the sub-machine 20, and when the sub-machine 20 is located in the region around the user, the sub-machine 20 may be located in a region with a radius a around the user, and the value range of a is 1 to 2 m. Thus, the user can be positioned or located near the negative pressure area of the sub-machine 20, which is beneficial to quickly adjusting the temperature of the area around the user and can avoid discomfort caused by the fact that the sub-machine 20 is too close to the user.

In some optional embodiments of the present invention, referring to fig. 7, in an embodiment in which the sub-set 20 moves to the area around the user and then blows air to the user and moves around the user, the initial rotation speed of the sub-set 20 may be determined according to the distance between the sub-set 20 and the user. Therefore, the rotating speed of the submachine 20 can be matched with the distance between the position of the user and the submachine 20, the air conveyed by the submachine 20 can have proper speed and wind power after reaching the user, the body surface temperature of the user and the temperature of the area near the user can be quickly adjusted, the air conveyed by the submachine 20 can be guaranteed to be softer after reaching the user, and the comfort is further improved.

In the embodiment that the sub-machine moves to the area around the user and then supplies air to the user and moves around the user, the distance between the sub-machine 20 and the user refers to the distance between the sub-machine 20 and the user before the sub-machine 20 moves to the area around the user and does not move around the user; when the slave unit 20 is already located in the area around the user, the distance between the slave unit 20 and the user is the distance between the slave unit 20 and the user before the slave unit 20 moves around the user.

Further, in the embodiment that the air is supplied to the user and moves around the user after the sub-machine 20 moves to the area around the user, the initial rotation speed of the sub-machine 20 may be determined according to the distance between the sub-machine 20 and the user, and may also be corrected according to the initial temperature of the indoor environment. The initial speed of the slave unit 20 is determined by increasing the initial value of the indoor ambient temperature and correcting the initial value, and the rotation speed of the slave unit 20 is corrected to some extent according to the difference between the initial values of the indoor ambient temperature. Therefore, the initial rotating speed of the sub machine 20 can be determined by taking the distance between the sub machine 20 and the user into consideration, and simultaneously taking the indoor environment temperature into consideration, under the condition that the distance between the sub machine 20 and the user is the same, if the initial value of the indoor environment temperature is different, for example, when an air conditioner operates in a refrigerating mode, if the initial value of the indoor environment temperature is higher, the initial rotating speed of the sub machine 20 is relatively set to be larger relative to the condition that the initial value of the indoor environment temperature is lower, and thus under the condition that the indoor environment temperature is higher, the body surface temperature of the user and the temperature of the area near the user can be rapidly reduced.

Optionally, after the hot air/cold air conveyed by the sub-machine 20 reaches the user, the body surface air speed of the user is 0.2m/s to 0.5m/s, for example, the body surface air speed of the user may be 0.3m/s, so that the body surface temperature of the user and the temperature of the area near the user can be adjusted relatively quickly, and the user feels relatively soft after the hot air/cold air conveyed by the sub-machine 20 reaches the user, thereby further improving the comfort.

According to some embodiments of the present invention, referring to fig. 8, the controlling the sub-phone 20 to blow air towards the user may include:

the distance between the user position and the submachine 20 is collected, and the distance between the user position and the submachine 20 can be measured through an infrared camera on the submachine 20;

and controlling the sub-machine 20 to switch to the corresponding air supply mode for air supply according to the distance between the user position and the sub-machine 20. Thus, according to the distance between the user position and the sub-machine 20, the sub-machine 20 is switched to the corresponding air supply mode, and the air supply mode of the sub-machine 20 is different at different distances, so that the air blown out by the sub-machine 20 can be delivered to the user, and the air blown out by the sub-machine 20 can be delivered to the user, relatively softer, and uncomfortable feeling caused by air supply of the sub-machine 20 to the user can be reduced.

For example, in some alternative embodiments of the present invention, referring to fig. 4 and 5, the sub-machine 20 may include a first fan 231 and a second fan 232, the first fan 231 is a centrifugal fan, the second fan 232 is an axial flow fan, a cross flow fan or a counter-rotating fan, and the different fans are turned on in different air supply modes, so that the air supply distances in the different air supply modes are different, and the air supply effects are different, so that when the distance between the user location and the sub-machine 20 is different, the different fans may be turned on to supply air to the user in the different air supply modes by the sub-machine 20.

For example, when the distance between the user position and the slave unit 20 is large, only the first fan 231 may be turned on, the first fan 231 is a centrifugal fan, the air supply speed of the centrifugal fan is large, and the air supply direction is concentrated, so that the air supply distance of the first fan 231 is long, the slave unit 20 may convey the blown air to the user position, and in the conveying process, the conveying distance is large, and the hot/cold air reaching the user may be soft.

For example, when the distance between the user position and the sub-machine 20 is small, only the second fan 232 may be turned on, the second fan 232 is an axial flow fan, a cross flow fan or a counter-rotating fan, when the second fan 232 is a counter-rotating fan, the counter-rotating fan includes two coaxial and opposite axial flow wind wheels, the second fan 232 may adopt a soft air supply mode, compared with the centrifugal fan, the axial flow fan and the cross flow fan have small air supply speed and large air supply angle, the air outlet is relatively divergent, so that the air supply distance of the second fan 232 is large, the air blown out by the sub-machine 20 may be delivered to the user position, and the hot/cold air reaching the user may be relatively soft.

For another example, if the second fan 232 is located at the downstream side of the first fan 231, when the distance between the user position and the slave unit 20 is small, the first fan 231 and the second fan 232 may be simultaneously turned on, and after the air passing through the first fan 231 is softened by the second fan 232, the air supply distance of the slave unit 20 may also be small, so that the slave unit 20 may deliver the blown air to the user position, and the hot/cold air reaching the user may be soft.

It should be noted that "the second fan 232 is located downstream of the first fan 231" in the present invention is relative to the flowing direction of the airflow in the handset 20.

According to some alternative embodiments of the present invention, referring to fig. 8, controlling the sub-unit 20 to switch to the corresponding air blowing mode for blowing air according to the distance between the user position and the sub-unit 20 may include:

when the distance between the user position and the submachine 20 is greater than the preset distance, which indicates that the distance between the user and the submachine 20 is greater at this time, the submachine 20 is controlled to be switched to the first air supply mode, and the submachine 20 can realize long-distance conveying in the first air supply mode, so that the air blown out by the submachine 20 can be conveyed to the position of the user;

when the distance between the user position and the submachine 20 is not greater than the preset distance, it is described that the distance between the user and the submachine 20 is smaller at this time, the submachine 20 is controlled to be switched to the second air supply mode, the air supply distance of the first air supply mode is greater than the air supply distance of the second air supply mode, the submachine 20 can realize closer distance conveying in the second air supply mode, so that the air blown out from the submachine 20 can be conveyed to the position of the user, and discomfort caused by direct blowing of the submachine 20 in a close distance can be avoided.

The distance between the user position and the slave unit 20 is the distance between the slave unit 20 and the user before the slave unit 20 moves around the user. In the process of moving the slave unit 20 around the user, the distance between the slave unit 20 and the user position is substantially the same, and even if there is a change, the change is small and negligible.

Alternatively, the preset distance may be determined according to the maximum blowing distance of the sub-machine 20 in the second blowing mode. For example, when the slave unit 20 includes the first fan 231 and the second fan 232 described above, only the first fan 231 is turned on to operate when the slave unit 20 is in the first air blowing mode, only the second fan 232 is turned on to operate when the slave unit 20 is in the second air blowing mode, or both the first fan 231 and the second fan 232 are turned on (in a case where the second fan 232 is located on the downstream side of the first fan 231).

According to some optional embodiments of the present invention, referring to fig. 8, controlling the sub-unit 20 to switch to the corresponding air blowing mode for blowing air according to the distance between the user position and the sub-unit 20, may further include:

the rotating speed of the sub-machine 20 in the corresponding air supply mode is determined according to the distance between the user position and the sub-machine 20, and the rotating speed of the sub-machine 20 in the air supply mode can be further determined according to the distance between the user position and the sub-machine 20 while the sub-machine 20 is controlled to be switched to the corresponding air supply mode for air inlet and air supply by judging the size relation between the distance between the user position and the sub-machine 20 and the preset distance. Therefore, when the submachine 20 is switched to the corresponding air supply mode, the rotating speed of the submachine 20 can be further optimized while the submachine 20 is used for conveying the blown air to the position of the user, so that the rotating speed of the submachine 20 in the air supply mode is more matched with the distance between the position of the user and the submachine 20, the air blown out by the submachine 20 can reach the user at a proper speed and wind power, the body surface temperature of the user and the temperature of the area near the user can be quickly adjusted, the hot air/cold air conveyed by the submachine 20 can be guaranteed to be softer after reaching the user, and the comfort is further improved.

For example, when the distance between the user position and the slave unit 20 is greater than the preset distance, the slave unit 20 is controlled to switch to the first air blowing mode, and the rotation speed of the slave unit 20 is determined based on the distance between the user position and the slave unit 20. When the slave unit 20 includes the first fan 231 and the second fan 232, only the first fan 231 operates in the first air blowing mode of the slave unit 20, and the rotation speed of the first fan 231 can be determined according to the distance between the user position and the slave unit 20.

For another example, when the distance between the user position and the slave unit 20 is not greater than the preset distance, the slave unit 20 is controlled to switch to the second air blowing mode, and the rotation speed of the slave unit 20 is determined according to the distance between the user position and the slave unit 20. When the slave unit 20 includes the first fan 231 and the second fan 232, only the second fan 232 of the slave unit 20 operates in the second air supply mode, and the rotation speed of the second fan 232 may be determined according to the distance between the user position and the slave unit 20; or, when the slave unit 20 includes the first fan 231 and the second fan 232, the second fan 232 is located on the downstream side of the first fan 231, and the first fan 231 and the second fan 232 both operate in the second air supply mode of the slave unit 20, the rotation speeds of the first fan 231 and the second fan 232 may be determined according to the distance between the user position and the slave unit 20, and the rotation speed of the second fan 232 may be mainly adjusted according to the distance between the user position and the slave unit 20.

In some optional embodiments of the present invention, controlling the sub-unit 20 to switch to the corresponding air supply mode for supplying air according to the distance between the user position and the sub-unit 20 further includes:

and correcting the initial rotating speed of the sub-machine 20 in the corresponding air supply mode according to the initial temperature of the indoor environment. The initial speed of the slave unit 20 is determined by increasing the initial value of the indoor ambient temperature and correcting the initial value, and the rotation speed of the slave unit 20 is corrected to some extent according to the difference between the initial values of the indoor ambient temperature. Therefore, the initial rotating speed of the sub machine 20 can be determined by taking the distance between the sub machine 20 and the user into consideration, and simultaneously taking the indoor environment temperature into consideration, under the condition that the distance between the sub machine 20 and the user is the same, if the initial value of the indoor environment temperature is different, for example, when an air conditioner operates in a refrigerating mode, if the initial value of the indoor environment temperature is higher, the initial rotating speed of the sub machine 20 is relatively set to be larger relative to the condition that the initial value of the indoor environment temperature is lower, and thus under the condition that the indoor environment temperature is higher, the body surface temperature of the user and the temperature of the area near the user can be rapidly reduced.

For example, in some embodiments of the present invention, referring to fig. 6, a control method of an air conditioner is described by taking an air conditioner cooling operation as an example, and the control method of the air conditioner may include:

s01, controlling the air conditioner to perform refrigeration operation;

s06, determining that the air supply of the submachine 20 to the user reaches a second preset time;

s07, collecting the body surface temperature of the user;

s08, determining that the body surface temperature of the user is not higher than a preset comfortable temperature;

and S09, controlling the slave unit 20 to reduce the rotating speed.
