[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The control method of an air conditioner according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0036] like Figures 1-3 As shown, according to a first aspect embodiment of the air conditioner control method of the present invention, the air conditioner may include a main unit 10 and a sub-unit 20, wherein the sub-unit 20 may be detachably disposed within the main unit 10. For example, a sub-unit 20 cavity 13 for installing and accommodating the sub-unit 20 may be formed within the main unit 10, and the sub-unit 20 may be disposed within the sub-unit 20 cavity 13. A separation port 14 may be formed on one side of the sub-unit 20 cavity 13 (e.g., the front side of the sub-unit 20 cavity 13), through which the sub-unit 20 may be installed into the sub-unit 20 cavity 13 of the main unit 10, or the sub-unit 20 may be automatically moved into the sub-unit 20 cavity 13 of the main unit 10 through the separation port 14, or the sub-unit 20 may be removed from the sub-unit 20 cavity 13 of the main unit 10 through the separation port 14, or the sub-unit 20 may be automatically moved from the sub-unit 20 cavity 13 of the main unit 10 to the outside of the main unit 10 to the indoor floor through the separation port 14.

[0037] The separation opening 14 can be provided with a separation door 15 for opening and closing the separation opening 14. The separation door 15 can be rotatably arranged at the separation opening 14, and the opening and closing of the separation opening 14 can be realized by rotating the separation door 15. Alternatively, the air conditioner can comprise a driving mechanism for driving the separation door 15 to rotate, and the automatic opening and closing of the separation opening 14 by the separation door 15 can be realized by driving the separation door 15 to rotate by the driving mechanism. For example, when the sub-machine 20 needs to be moved out of the main machine 10, the driving mechanism can be controlled to drive the separation door 15 to rotate to open the separation opening 14, and the sub-machine 20 can be automatically moved out of the sub-machine 20 cavity 13 and to the indoor floor through the separation opening 14. When the sub-machine 20 needs to be moved into the sub-machine 20 cavity 13 of the main machine 10, the sub-machine 20 can be automatically moved into the sub-machine 20 cavity 13, and after the sub-machine 20 is moved into the sub-machine 20 cavity 13, the driving mechanism can be controlled to drive the separation door 15 to rotate to close the separation opening 14.

[0038] The main machine 10 can comprise a main machine shell 11 and a heat exchange and air supply unit arranged in the main machine shell 11. The main machine shell 11 is provided with an air return opening 111 and an air supply opening. The heat exchange and air supply unit can comprise a heat exchanger component and a main fan component. When the main machine 10 is working, the main fan component drives external air to enter the main machine shell 11 from the air return opening 111, exchanges heat with the heat exchanger component, and is blown out to the indoor through the air supply opening, so as to adjust the indoor environment temperature and realize refrigeration / heat.

[0039] The main machine shell 11 can define the above-mentioned sub-machine 20 cavity 13 and a containing cavity. The heat exchange and air supply unit can be arranged in the containing cavity, and the sub-machine 20 can be installed in the sub-machine 20 cavity 13. The sub-machine 20 cavity 13 and the containing cavity can be arranged separately. For example, a partition plate can be arranged in the main machine shell 11 to separate the space in the main machine shell 11 into the sub-machine 20 cavity 13 and the containing cavity.

[0040] Alternatively, the sub-machine 20 cavity 13 can be located below the containing cavity, which facilitates the installation of the sub-machine 20 into the sub-machine 20 cavity 13 or the automatic movement of the sub-machine 20 into the sub-machine 20 cavity 13, and facilitates the removal of the sub-machine 20 from the sub-machine 20 cavity 13 or the automatic movement of the sub-machine 20 from the sub-machine 20 cavity 13 to the indoor floor. Further, the bottom wall of the sub-machine 20 cavity 13 can serve as the bottom wall of the main machine shell 11, and the bottom wall of the sub-machine 20 cavity 13 can be directly in contact with the floor. The bottom wall of the sub-machine 20 cavity 13 can be arranged to be relatively thin, so as to facilitate the automatic movement of the sub-machine 20 from the indoor floor into the sub-machine 20 cavity 13 or the automatic movement of the sub-machine 20 from the sub-machine 20 cavity 13 to the indoor floor.

[0041] The air conditioner can be a split type air conditioner, for example, the air conditioner can be a split floor type air conditioner or a split wall type air conditioner. When the air conditioner is a split type air conditioner, the air conditioner comprises an air conditioner indoor unit 100 and an air conditioner outdoor unit, and the air conditioner indoor unit 100 comprises the above-mentioned main unit 10 and the subunit 20. For example, when the air conditioner is a split floor type air conditioner, the air conditioner indoor unit 100 comprises the above-mentioned main unit 10 and the subunit 20.

[0042] For example, in some specific examples of the present application, with reference to Figures 1-3 , the air conditioner is a split floor type air conditioner, and the air conditioner comprises an air conditioner indoor unit 100 and an air conditioner outdoor unit, wherein the air conditioner indoor unit 100 comprises the above-mentioned main unit 10 and the subunit 20. The main unit 10 comprises a main unit shell 11 and a heat exchange and air supply unit, the main unit shell 11 defines an accommodating cavity and a subunit cavity 13 arranged in an upper and lower spaced manner, the accommodating cavity is located above the subunit cavity 13, the heat exchange and air supply unit is installed in the accommodating cavity, and the subunit 20 can be installed in the subunit cavity 13. A return air inlet 111 is formed on the rear side wall of the accommodating cavity, and an air supply outlet is formed on the front side wall of the accommodating cavity, and a switch door 12 for opening and closing the air supply outlet is arranged at the air supply outlet.

[0043] The subunit 20 can be separated from the main unit 10 and placed on the ground, and the subunit 20 can automatically move according to requirements.

[0044] The subunit 20 can comprise a subunit shell 21 and an air supply processing unit, the air supply processing unit is arranged in the subunit shell 21, the subunit shell 21 is formed with an air inlet and an air outlet, the air supply processing unit can comprise a sub-fan component 23, and the subunit 20 itself can not have a heating / cooling function. When the subunit 20 is working, the sub-fan component 23 operates to drive external air to enter the subunit shell 21 from the air inlet and then blow out to the indoor from the air outlet. The air supply processing unit can further comprise a humidification module, so that the subunit 20 has a humidification function, which can humidify the indoor air and improve the indoor air quality. Moreover, when the subunit 20 moves to the vicinity of the user, the subunit 20 can quickly humidify the air in the vicinity of the user.

[0045] Optionally, the humidification module can comprise a humidification assembly and a water tank 25 for supplying water to the humidification assembly, and the humidification module can further comprise a water pump for conveying water in the water tank 25 to the humidification assembly. The humidification assembly can comprise a humidification support and a wet cotton assembly arranged on the humidification support, and the water pump can pump water in the water tank 25 to the wet cotton assembly. When the sub-fan component 23 is working, the airflow can pass through the wet cotton assembly to take away the water on the wet cotton assembly, so as to humidify the indoor air. Wherein, the start and stop of the humidification module can be conveniently controlled by controlling the start and stop of the water pump.

[0046] Optionally, the air supply processing unit can further comprise a purification module, so that the sub-machine 20 has both humidification and purification functions, so that the sub-machine 20 can humidify and / or purify the indoor air to improve the indoor air quality. When the sub-machine 20 moves to the vicinity of the user, the sub-machine 20 can quickly humidify and / or purify the air near the user.

[0047] The sub-machine 20 can communicate with the main machine 10, and 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 main machine 10 can also transmit the collected information to the sub-machine 20, and the working condition of the main machine 10 can also be transmitted to the sub-machine 20. When the sub-machine 20 is separated from the main machine 10, the sub-machine 20 can move, for example, the bottom of the sub-machine 20 can be provided with wheels 22, which can be universal wheels, so that the sub-machine 20 can move in any direction. For example, when the sub-machine 20 is separated from the main machine 10 and placed on the ground, the sub-machine 20 can collect the user's position, and the sub-machine 20 can automatically move to the vicinity of the user to blow air on the user or to humidify / purify the air near the user. Of course, the sub-machine 20 can also move to other positions according to the specific instructions of the user. Through the movement of the sub-machine 20 in the room, the air supply range of the main machine 10 can be expanded, which is beneficial to enhancing the flow of indoor air, thereby facilitating the uniformization of the indoor environment temperature. After the main machine 10 is turned on, the sub-machine 20 can work according to the user's instructions or the set program, so that the working of the entire air conditioner is more flexible and the function is more diversified, which meets more needs of the user.

[0048] The main machine 10 can work independently. The sub-machine 20 can be completely controlled by the main machine 10 to work, and the sub-machine 20 cannot work independently when the main machine 10 is not turned on; the sub-machine 20 can also work independently without being controlled by the main machine 10, for example, the sub-machine 20 can also work independently when the main machine 10 is not turned on. When the main machine 10 and the sub-machine 20 are both turned on, the main machine 10 and the sub-machine 20 can communicate with each other, which facilitates the information transmission between the main machine 10 and the sub-machine 20, thereby facilitating better control of the sub-machine 20 and the main machine 10.

[0049] Optionally, the air inlet of the sub-machine 20 is located below the air outlet of the sub-machine 20. After the main machine 10 is turned on, the sub-machine 20 can move to a set position, for example, the sub-machine 20 can move to the vicinity of the user, and because the air inlet of the sub-machine 20 is located low, the sub-machine 20 can suck the air from the low place into the sub-machine 20 and blow it upwards, which is beneficial to enhancing the flow of indoor air, thereby facilitating the uniformization of the indoor environment temperature.

[0050] For example, when the main machine 10 of the air conditioner is in refrigeration operation, the cold air flow is lowered under the action of its own gravity, the sub-machine 20 can transport the air flow with lower temperature at the lower place to the higher place, realize air disturbance, realize the air temperature at the higher place to be relatively lowered by the air flow with lower temperature at the lower place moving upward, and make the air flow at the higher place more flowable; and the sub-machine 20 forms a negative pressure area near the air inlet, so that the air flow with higher temperature at the higher place flows downward, realize the air temperature at the lower place to be relatively raised, which can accelerate and strengthen the flow of indoor air, thereby being beneficial to accelerate the temperature homogenization of indoor environment. When the sub-machine 20 moves to the vicinity of the user, the air in the vicinity of the user can be made to be relatively uniform in temperature from top to bottom, and the comfort is improved.

[0051] For example, when the main machine 10 of the air conditioner is in refrigeration operation, the cold air flow is lowered under the action of its own gravity, the sub-machine 20 can transport the air flow with lower temperature at the lower place to the higher place, realize air disturbance, realize the air temperature at the higher place to be relatively lowered by the air flow with lower temperature at the lower place moving upward, and make the air flow at the higher place more flowable; and the sub-machine 20 forms a negative pressure area near the air inlet, so that the air flow with higher temperature at the higher place flows downward, realize the air temperature at the lower place to be relatively raised, which can accelerate and strengthen the flow of indoor air, thereby being beneficial to accelerate the temperature homogenization of indoor environment. When the sub-machine 20 moves to the vicinity of the user, the air in the vicinity of the user can be made to be relatively uniform in temperature from top to bottom, and the comfort is improved.

[0052] Optionally, the sub-machine 20 can also realize rotation, and the blowing direction of the sub-machine 20 in the horizontal direction can be adjusted and changed through the rotation of the sub-machine 20. For example, the sub-machine 20 can include a base 24 and a sub-machine 20 body provided on the base 24, the sub-machine 20 body includes the above-mentioned air blowing and processing unit, the bottom of the base 24 can be provided with wheels 22 to realize the movement of the sub-machine 20, the sub-machine 20 body can rotate relative to the base 24, and the sub-machine 20 can include a sub-machine 20 rotating mechanism for driving the sub-machine 20 body to rotate relative to the base 24. The rotation axis of the sub-machine 20 body can extend in the up-down direction, and the sub-machine 20 body can rotate 360° relative to the base 24, so that no matter where the user is located in the room, the sub-machine 20 can control the sub-machine 20 rotating mechanism to drive the sub-machine 20 body to rotate to make the air outlet of the sub-machine 20 face the user according to the specific position of the user relative to the sub-machine 20, thereby conveniently realizing the adjustment and change of the blowing direction of the sub-machine 20 in the horizontal direction.

[0053] The control method of the air conditioner includes:

[0054] The main machine 10 is controlled to be in heating operation, so that the indoor environment temperature can be improved;

[0055] determining that the user is not within the air supply range of the main machine 10, the user position can be collected to determine whether the user is within the air supply range of the main machine 10, the user position can be collected by the main machine 10 or the sub-machine 20, for example, the user position can be collected by the infrared camera on the sub-machine 20 or the infrared camera on the main machine 10, the user position can be collected to determine whether the user is within the air supply range of the main machine 10, if the user is within the air supply range of the main machine 10, the hot air output by the air outlet of the main machine 10 can reach the user's location, quickly raising the user's body surface temperature or the temperature of the area near the user; in the case of determining that the user is not within the air supply range of the main machine 10, it means that the hot air output by the air outlet of the main machine 10 cannot reach the user's location, and the user's body surface temperature and the temperature of the area near the user cannot be quickly adjusted;

[0056] controlling the sub-machine 20 to move into the air supply range of the main machine 10, after the sub-machine 20 moves into the air supply range of the main machine 10, the sub-machine 20 stops moving, after the sub-machine 20 moves into the air supply range of the main machine 10, the sub-machine 20 is controlled to blow air towards the user, since the user is not within the air supply range of the main machine 10, the temperature of the area around the user cannot be quickly adjusted, by moving the sub-machine 20 into the air supply range of the main machine 10 and making the sub-machine 20 blow air towards the user, the sub-machine 20 can relay the heat of the main machine 10 to deliver heat to the user, so as to quickly adjust the user's body surface temperature or the temperature of the area around the user, so that the temperature of the area around the user or the user's body surface temperature is quickly adjusted to a more comfortable temperature range, improving the comfort of the air conditioner and meeting more and higher demands of the user;

[0057] after the sub-machine 20 moves into the air supply range of the main machine 10 to relay the heat of the main machine 10 to the user's location, the user's body surface temperature or the temperature of the area around the user can be collected, and it is determined that the user's body surface temperature is less than the first preset temperature or the temperature of the area around the user is less than the first set temperature, which means that the user's demand for heat has not been met at this time;

[0058] adjusting the operating parameters of the main machine 10, the operating parameters including at least one of the operating frequency of the compressor and the rotating speed of the main fan component of the heat exchange and air supply unit, by adjusting at least one of the operating frequency of the compressor and the rotating speed of the main fan component of the heat exchange and air supply unit, the sub-machine 20 can more effectively relay more heat of the main machine 10 and deliver to the user's location, so as to more effectively raise the user's body surface temperature or the temperature of the area around the user, and better meet the user's demand for heat.

[0059] The operation parameter of the host 10 can be adjusted, which can only adjust the operation frequency of the compressor, for example, the operation frequency of the compressor can be increased or decreased, so that the sub-machine 20 can more effectively relay more heat of the host 10 and deliver to the user location; it can also only adjust the rotating speed of the main fan component, for example, the rotating speed of the main fan component can be increased or decreased, so that the sub-machine 20 can more effectively relay more heat of the host 10 and deliver to the user location; it can also be to adjust the frequency of the compressor and adjust the rotating speed of the main fan component, for example, the operation frequency of the compressor can be increased, the rotating speed of the main fan component can be decreased, for example, the operation frequency of the compressor can be decreased, the rotating speed of the main fan component can be increased, so that the sub-machine 20 can more effectively relay more heat of the host 10 and deliver to the user location.

[0060] The user body temperature can be collected by the infrared sensor arranged on the host 10 or the sub-machine 20; the temperature of the user surrounding area can be collected by the temperature sensor arranged on the sub-machine 20, for example, the sub-machine 20 moves to the user surrounding area to collect the temperature of the user surrounding area, and after the collection is completed, it returns to the original position or the air supply range of the host 10 and continues to air supply to the user.

[0061] Optionally, the "user surrounding area" can be determined according to the negative pressure area formed by the sub-machine 20 when working. When the sub-machine 20 works, a negative pressure area is formed near the air inlet of the sub-machine 20. When the sub-machine 20 is located in the user surrounding area, the size of the user surrounding area can be determined according to the size of the negative pressure area formed by the sub-machine 20 when working, so that the user can be located or in the vicinity of the negative pressure area of the sub-machine 20. In this way, when the sub-machine 20 works, the sub-machine 20 can enhance the airflow flow of the user surrounding area, thereby facilitating rapid adjustment of the temperature of the user surrounding area, so that the temperature of the user surrounding area is rapidly adjusted to a more comfortable temperature range, and in particular, the temperature of the user surrounding area can be adjusted to a comfortable temperature range.

[0062] Optionally, the "user surrounding area" can be located in a range area with the user as the center and a radius of a, and the value range of a is 1-2m. In this way, the user can be located or in the vicinity of the sub-machine 20. In this way, when the sub-machine 20 works, the sub-machine 20 can enhance the airflow flow of the user surrounding area, thereby facilitating rapid adjustment of the temperature of the user surrounding area, so that the temperature of the user surrounding area is rapidly adjusted to a more comfortable temperature range, and in particular, the temperature of the user surrounding area can be adjusted to a comfortable temperature range; and discomfort caused by the sub-machine 20 being too close to the user can be avoided. Further, the value range of a is 1.5-2m, for example, a can be 1.5m, 1.8m, 2m, etc.

[0063] For example, in some embodiments of the present application, the size of the negative pressure area formed when the sub-machine 20 rotates at the highest speed is used to determine the size of the user's surrounding area. For example, when the sub-machine 20 rotates at the highest speed, a negative pressure area with a distance of a from the sub-machine 20 is formed near the air inlet of the sub-machine 20. When the sub-machine 20 is located in the user's surrounding area, the sub-machine 20 can be located in a range area centered on the user with a radius of a, and a is in the range of 1-2 m. In this way, the user can be located near the negative pressure area of the sub-machine 20, thereby facilitating rapid adjustment of the temperature and humidity of the user's surrounding area, and avoiding discomfort caused by the sub-machine 20 being too close to the user.

[0064] After the main machine 10 of the air conditioner is in heating operation, by collecting the user's position, if the user is not in the air supply range of the main machine 10, by controlling the sub-machine 20 to move to the air supply range of the main machine 10, the sub-machine 20 relays the heat of the main machine 10, and the sub-machine 20 delivers the hot air output by the main machine 10 to the user's position, so as to rapidly adjust the user's body surface temperature or the temperature of the user's surrounding area, and make the temperature of the user's surrounding area quickly reach the comfortable range. When the user is in the air supply range of the main machine 10, the hot air output by the main machine 10 can be directly delivered to the user's position, so as to rapidly increase the user's body surface temperature or the temperature of the user's surrounding area, and the sub-machine 20 does not need to move to the air supply range of the main machine 10 to relay the hot air and deliver it to the user. In this way, the user's demand is met while the energy consumption is reduced. Even if the user is not in the air supply range of the main machine 10 or the distance between the user and the main machine 10 is far, the heat of the main machine 10 can be directly or indirectly delivered to the user, so as to rapidly adjust the user's body surface temperature or the temperature of the user's surrounding area, and meet the user's more and higher demands.

[0065] According to the control method of the air conditioner of the embodiments of the present application, when the user is not in the air supply range of the main machine 10, by controlling the sub-machine 20 to move to the air supply range of the main machine 10, the heat of the main machine 10 is delivered to the user's position, so as to rapidly adjust the user's body surface temperature and the temperature of the user's surrounding area. In this way, when the user is not in the air supply range of the main machine 10 or is far away from the main machine 10, the temperature of the user's surrounding area and the user's body surface temperature can be rapidly increased, so as to make the temperature of the user's surrounding area quickly reach the comfortable temperature range, and meet the user's more and higher demands. When the user's body surface temperature or the temperature of the user's surrounding area does not meet the user's demand, the operating parameters of the main machine 10 can be adjusted, so that the sub-machine 20 can relay more heat of the main machine 10 to the user, thereby more effectively adjusting the temperature of the user's surrounding area and the user's body surface temperature.

[0066] According to some embodiments of the present application, refer to Figure 6Before the sub-machine 20 is controlled to move into the air supply range of the main machine 10, it is determined that the return air temperature of the main machine 10 is greater than a set return air temperature, and the set return air temperature can be 15-18℃, for example, the set return air temperature can be 15℃, 16℃, 17℃, 18℃, etc. After the main machine 10 starts the heating operation, the main machine 10 can keep running for a period of time to raise the temperature of the entire indoor environment. When it is detected that the return air temperature of the main machine 10 is greater than the set return air temperature, it indicates that the temperature of the entire indoor environment has generally risen to a relatively warm degree, but the user is not in the air supply range of the main machine 10, and the temperature of the user's body surface or the temperature of the user's surrounding area has not reached a relatively comfortable temperature. At this time, the sub-machine 20 can be controlled to move into the air supply range of the main machine 10 to relay the heat of the main machine 10 and deliver it to the position where the user is located, so as to adjust the temperature around the user in a targeted manner, thereby quickly and effectively raising the temperature of the user's body surface or the temperature of the user's surrounding area.

[0067] According to some embodiments of the present application, with reference to Figure 6 Before the user's body surface temperature or the temperature of the user's surrounding area is collected and determined to be less than the first preset temperature or the first set temperature, it is determined that the sub-machine 20 is controlled to blow air towards the user in the air supply range of the main machine 10 for a set time period. After the sub-machine 20 moves into the air supply range of the main machine 10 to relay the heat of the main machine 10 and deliver hot air towards the user for a set time period to raise the temperature of the user's body surface or the temperature of the user's surrounding area, the temperature of the user's body surface or the temperature of the user's surrounding area is collected again, and it is determined that the user's body surface temperature or the temperature of the user's surrounding area is less than the first preset temperature or the first set temperature. It indicates that the sub-machine 20 has failed to effectively and quickly raise the temperature of the user's body surface or the temperature of the user's surrounding area. Based on this, the operating parameters of the main machine 10 can be adjusted. Specifically, at least one parameter of the operating frequency of the compressor and the rotating speed of the main fan part of the heat exchange air supply unit is adjusted, so that the sub-machine 20 can more effectively relay more heat of the main machine 10 and deliver it to the position where the user is located, thereby more effectively raising the temperature of the user's body surface or the temperature of the user's surrounding area, and better meeting the user's demand for heat.

[0068] Optionally, the first set temperature is not less than the set return air temperature, and the first set temperature can be 15-18℃, for example, the first set temperature can be 15℃, 16℃, 17℃, 18℃, etc.

[0069] According to some embodiments of the present application, the control of the sub-machine 20 to move into the air supply range of the main machine 10 can include:

[0070] The negative pressure area formed when the sub-machine 20 works. When the sub-machine 20 works, a negative pressure area will be formed near the air inlet of the sub-machine 20, and the airflow flows to the negative pressure area under the action of pressure difference and enters the sub-machine 20 through the air inlet;

[0071] The control sub-machine 20 moves to at least part of the negative pressure area of the sub-machine 20 is located in the air supply range of the main machine 10, for example, can be part of the negative pressure area of the sub-machine 20 is located in the air supply range of the main machine 10, can also be the whole negative pressure area of the sub-machine 20 is located in the air supply range of the main machine 10. By making at least part of the negative pressure area of the sub-machine 20 is located in the air supply range of the main machine 10, the sub-machine 20 can better relay the main machine 10 heat, more heat of the main machine 10 is transported to the user location.

[0072] For example, in the process of moving the sub-machine 20, the air inlet position of the sub-machine 20 can be detected in real time, and whether at least part of the negative pressure area of the sub-machine 20 is in the air supply range of the main machine 10 is determined according to the air inlet position of the sub-machine 20, to determine whether the sub-machine 20 moves to the air supply range of the main machine 10. When it is determined that at least part of the negative pressure area of the sub-machine 20 is in the air supply range of the main machine 10, the sub-machine 20 can be controlled to stop moving, so that the sub-machine 20 moves to the air supply range of the main machine 10. By determining whether at least part of the negative pressure area of the sub-machine 20 is in the air supply range of the main machine 10 according to the air inlet position of the sub-machine 20, and as the basis for determining that the sub-machine 20 moves to the air supply range of the main machine 10, when the sub-machine 20 is in the air supply range of the main machine 10, the air inlet area of the sub-machine 20 can be located in the air supply range of the main machine 10, so that the sub-machine 20 can accelerate the hot air sent by the main machine 10 into the sub-machine 20 through the air inlet, and then send it to the user through the air outlet of the sub-machine 20, so that the sub-machine 20 can better relay the heat of the main machine 10, so that more heat can be transported to the user, and the user's body surface temperature and the temperature of the area near the user can be quickly adjusted.

[0073] In order to make the sub-machine 20 relay the heat of the main machine 10 as much as possible and better, the application determines the heat rising area in the air supply range of the main machine 10 when the air conditioner is in heating operation, for the convenience of description, the heat rising area can be called hot air zone. So that the sub-machine 20 not only moves to the air supply range of the main machine 10, but also moves to the position corresponding to the heat rising area.

[0074] For example, in some embodiments of the application, the control sub-machine 20 moves to the air supply range of the main machine 10 can include:

[0075] The indoor environment temperature and the air supply temperature of the main machine 10 can be collected by setting a temperature sensor at the air return port 111 of the main machine 10 to collect the air return temperature of the main machine 10, which can be used as the indoor environment temperature, and by setting a temperature sensor at the air supply port of the main machine 10 to collect the air supply temperature of the main machine 10, in other embodiments, the air supply temperature of the main machine 10 can also be calculated by collecting the frequency of the compressor.

[0076] Since the rising of hot air is mainly affected by the indoor ambient temperature and the air supply temperature of the main machine 10, and the air supply temperature of the main machine 10 is the most important factor affecting the rising of hot air, the higher the indoor ambient temperature and the air supply temperature of the main machine 10, the easier the hot air rises, the faster the hot air rises, and the hot air rising area in the air supply range of the main machine 10 is the hot air area, and the lowest point of the hot air area is the optimal position point of the sub-machine 20. When the sub-machine 20 is at the position corresponding to the hot air area, the lower the hot air area, the easier the sub-machine 20 relays more hot air, so that more hot air blown by the main machine 10 can be relayed and delivered to the user's position.

[0077] Generally, the higher the indoor ambient temperature and the air supply temperature of the main machine 10, the easier the hot air rises, and the closer the hot air area to the main machine 10; on the contrary, the lower the indoor ambient temperature and the air supply temperature of the main machine 10, the slower the hot air rises, and the farther the hot air area from the main machine 10. According to the indoor ambient temperature and the air supply temperature of the main machine 10, the hot air area in the air supply range of the main machine 10 can be determined more accurately, and the hot air area is the area with the most concentrated heat in the air supply range of the main machine 10.

[0078] After determining the hot air area of the main machine 10 according to the indoor ambient temperature and the air supply temperature of the main machine 10, the sub-machine 20 can be controlled to move to the position corresponding to the hot air area in the air supply range of the main machine 10, so that the sub-machine 20 moves to the area with the most concentrated heat in the air supply range of the main machine 10. In this way, the sub-machine 20 can relay more heat output by the main machine 10, so that the sub-machine 20 can deliver more heat to the user's position, so as to more quickly raise the user's body surface temperature and the temperature of the area near the user.

[0079] Alternatively, in some other optional embodiments of the present application, the determination of the hot air area can also adopt the following manner, specifically, the control of the sub-machine 20 to move to the air supply range of the main machine 10 can include:

[0080] Collecting the indoor ambient temperature, for example, the maximum air supply distance of the main machine 10 under the highest speed of the main fan component of the main machine 10 can be taken as a reference distance, and the indoor ambient temperature of multiple different area positions within the reference distance range from the main machine is collected;

[0081] According to the collected temperature data, a distribution map of the indoor ambient temperature is determined;

[0082] In the distribution map of the indoor ambient temperature, the area where the highest value of the indoor ambient temperature is located is compared and determined, and the area where the highest value of the indoor ambient temperature is located is the hot air area (i.e. the area with the highest temperature and the most concentrated heat);

[0083] The sub-machine 20 moves to the position corresponding to the hot air area, so that the sub-machine 20 moves to the area where the heat output by the main machine 10 is most concentrated, so that the sub-machine 20 can output more heat from the main machine 10, so that the sub-machine 20 can deliver more heat to the user's location, so that the user's body surface temperature and the temperature of the area near the user can be more quickly raised.

[0084] In some optional embodiments of the present application, according to the adjustment of the operating parameters of the main machine 10, the position of the sub-machine 20 is adjusted accordingly, so that the sub-machine 20 is in the hot air area. When the user is not in the air supply range of the main machine 10, the sub-machine 20 moves to the air supply range of the main machine 10 to relay the heat output by the main machine 10 to the user, the hot air area in the air supply range of the main machine 10 can be determined according to the indoor environment temperature and the air supply temperature of the main machine 10, and the sub-machine 20 is moved to the hot air area, so that the sub-machine 20 can more effectively relay more heat from the main machine 10 and deliver to the user. After the adjustment of the operating parameters of the main machine 10, for example, at least one of the operating frequency of the compressor and the rotating speed of the main fan component is adjusted, the hot air area relative to the position of the main machine 10 may change, so that the position of the sub-machine 20 is adjusted accordingly, so that the position of the sub-machine 20 is adjusted to the new hot air area, so that the sub-machine 20 can remain in the hot air area to more effectively relay more heat from the main machine 10 and deliver to the user.

[0085] In some embodiments, the operating parameters of the main machine 10 and the position of the hot air area are correspondingly related and stored in the memory of the air conditioner, and the air conditioner can obtain the position of the hot air area through the operating parameters of the main machine 10, wherein the corresponding relationship between the operating parameters of the main machine 10 and the hot air area can be obtained by experimental detection, and the operating parameters include the operating frequency of the compressor, the rotating speed of the main fan component, the guide angle of the guide vane, etc.

[0086] The operating frequency of the compressor affects the air supply temperature of the main machine 10. Generally, the higher the operating frequency of the compressor, the higher the air supply temperature of the main machine 10, and the lower the operating frequency of the compressor, the lower the air supply temperature of the main machine 10. The operating frequency of the compressor and the rotating speed of the main fan component also affect the indoor environment temperature, so the operating frequency of the compressor and the rotating speed of the main fan component both affect the position of the hot air area relative to the main machine 10, and also affect the height position of the hot air area.

[0087] According to some embodiments of the present application, the adjusting the operation parameter of the host 10 can comprise: adjusting the operation parameter of the host 10 according to the air supply temperature of the host 10. When it is determined that the user body surface temperature or the temperature of the user surrounding area is less than the first preset temperature, the operation parameter of the host 10 needs to be adjusted. In the process of adjusting the operation parameter of the host 10, the air supply temperature of the host 10 can be collected, and the operation parameter of the host 10 can be adjusted according to the air supply temperature of the host 10. For example, a temperature sensor for collecting the air supply temperature of the host 10 can be arranged near the air outlet of the host 10. The air supply temperature of the host 10 affects the distance between the hot air zone and the host 10 and the height position of the hot air zone. The air supply temperature of the host 10 and the position of the hot air zone both affect the effect of the sub-host 20 relaying the heat of the host 10 to the user. By collecting and adjusting the operation parameter of the host 10 according to the air supply temperature of the host 10, for example, by adjusting the operation frequency of the compressor and / or the rotating speed of the main fan component, the operation parameter of the host 10 can be adjusted in a direction that is more conducive to the sub-host 20 relaying the heat of the host 10 to more effectively raise the temperature of the user surrounding area, so that the adjustment of the operation parameter of the host 10 is more effective.

[0088] For example, in some optional embodiments of the present application, the adjusting the operation parameter of the host 10 according to the air supply temperature of the host 10 can comprise:

[0089] If the air supply temperature of the host 10 is greater than the set air supply temperature, it means that the temperature of the hot air zone is relatively high, which results in that the height position of the hot air zone is relatively high, and the lowest point of the hot air zone is also relatively high. Since the height position of the sub-host 20 is relatively low relative to the air outlet of the host 10, although the air supply temperature of the host 10 is relatively high, the effect of the sub-host 20 relaying the heat of the hot air zone is not good. At this time, the operation frequency of the compressor can be reduced to slightly reduce the air supply temperature of the host 10, so that the height position of the hot air zone is lowered, the lowest point of the hot air zone is also lowered, and the distance between the hot air zone and the host 10 is also changed. Specifically, the hot air zone is relatively farther away from the host 10. At this time, the sub-host 20 can be controlled to move to the position corresponding to the new hot air zone formed after the adjustment of the operation frequency of the compressor, and the sub-host 20 moves in the direction away from the host 10, so that the sub-host 20 moves to the new hot air zone. Since the height position of the new hot air zone is relatively low, the sub-host 20 can effectively relay more heat of the hot air zone, so that the sub-host 20 can deliver more heat of the host 10 to the position of the user, further rapidly raising the temperature of the user surrounding area or the user body surface temperature.

[0090] If the air supply temperature of the host 10 is not greater than the set air supply temperature, it indicates that the temperature of the hot air zone is relatively low. Although the height position of the hot air zone is relatively low and the lowest point of the hot air zone is relatively low, the sub-host 20 can relay more heat of the hot air zone. However, because the temperature of the hot air zone is relatively low, the temperature of the heat relayed by the sub-host 20 is relatively low, so that the temperature of the surrounding area of the user or the body surface temperature of the user cannot be effectively and quickly raised. At this time, the operating frequency of the compressor can be increased to slightly increase the air supply temperature of the host 10, so that the temperature of the hot air zone is increased. After the temperature of the hot air zone is increased, the distance of the hot air zone from the host 10 is also changed. Specifically, the hot air zone is relatively closer to the host 10. At this time, the sub-host 20 can be controlled to move to a position corresponding to a new hot air zone formed after the operating frequency of the compressor is adjusted. The sub-host 20 moves in a direction close to the host 10, so that the sub-host 20 moves to the new hot air zone.

[0091] Although the height position of the hot air zone and the lowest point of the hot air zone are relatively raised, the temperature of the hot air zone is considered as a whole. When the temperature of the hot air zone is relatively high, the height position of the hot air zone is relatively low, and the lowest point of the hot air zone is relatively low. The sub-host 20 can effectively relay more heat of the hot air zone, and the temperature of the hot air zone is relatively high, so that the sub-host 20 can deliver more heat of the host 10 to the position of the user, and further quickly raise the temperature of the surrounding area of the user or the body surface temperature of the user.

[0092] In addition, by reducing the frequency of the compressor, the sub-host 20 can effectively relay more heat of the hot air zone, so that the sub-host 20 can deliver more heat of the host 10 to the position of the user, and further quickly raise the temperature of the surrounding area of the user or the body surface temperature of the user. In this way, the user's demand can be met while reducing the heating capacity and energy consumption.

[0093] For example, in some optional embodiments of the present application, the adjusting the operating parameters of the host 10 according to the air supply temperature of the host 10 can include:

[0094] If the temperature of the air supply of the main host 10 is greater than the set temperature, it means that the temperature of the hot air zone is relatively high, which results in a higher height position of the hot air zone and a higher lowest point of the hot air zone. Since the height position of the sub-host 20 is relatively low relative to the air supply port of the main host 10, although the temperature of the air supply of the main host 10 is high, the sub-host 20 cannot effectively receive the heat of the hot air zone. At this time, the speed of the main fan component can be increased to lower the height position of the hot air zone and the lowest point of the hot air zone. Since the operating frequency of the compressor does not change, the temperature of the air supply of the main host 10 is basically unchanged, and the distance of the hot air zone relative to the main host 10 can also be considered to be basically unchanged. The sub-host 20 can remain in the original position. Since the height position of the hot air zone is lowered, the sub-host 20 can effectively receive more heat from the hot air zone, so that the sub-host 20 can deliver more heat from the main host 10 to the user's location, further rapidly increasing the temperature of the user's surrounding area or the user's body surface temperature.

[0095] If the temperature of the air supply of the main host 10 is not greater than the set temperature, it means that the temperature of the hot air zone is relatively low. Although the height position of the hot air zone is relatively low and the lowest point of the hot air zone is relatively low, the sub-host 20 can receive more heat from the hot air zone. However, since the temperature of the hot air zone is relatively low, the sub-host 20 cannot effectively and rapidly increase the temperature of the user's surrounding area or the user's body surface temperature. At this time, the speed of the main fan component can be reduced to make the air supply of the main host 10 more concentrated, so that more heat from the air supply port of the main host 10 is concentrated in the hot air zone. Since the operating frequency of the compressor does not change, the temperature of the air supply of the main host 10 is basically unchanged, and the distance of the hot air zone relative to the main host 10 can also be considered to be basically unchanged. The sub-host 20 can remain in the original position. Since more heat from the air supply port of the main host 10 is concentrated in the hot air zone, the sub-host 20 can effectively receive more heat from the hot air zone, so that the sub-host 20 can deliver more heat from the main host 10 to the user's location, further rapidly increasing the temperature of the user's surrounding area or the user's body surface temperature.

[0096] For example, in some optional embodiments of the present application, the operating parameters of the main host 10 are adjusted according to the temperature of the air supply of the main host 10, including:

[0097] If the temperature of the air supply of the main host 10 is greater than the set temperature, the operating frequency of the compressor is reduced and the speed of the main fan component is increased.

[0098] If the temperature of the air supply of the main host 10 is not greater than the set temperature, the operating frequency of the compressor is increased and the speed of the main fan component is reduced.

[0099] Specifically, in the above embodiment of adjusting the operation frequency of the compressor and adjusting the rotating speed of the main air blower component, if the air supply temperature of the main machine 10 is greater than the set air supply temperature, it indicates that the temperature of the hot air zone is relatively high, so that the height position of the hot air zone is relatively high, and the lowest point of the hot air zone is relatively high. Since the height position of the sub-machine 20 is relatively low relative to the air supply port of the main machine 10, although the air supply temperature of the main machine 10 is relatively high, the sub-machine 20 cannot effectively utilize the heat of the hot air zone. At this time, the operation frequency of the compressor can be reduced, so that the air supply temperature of the main machine 10 is slightly reduced, thereby reducing the height position of the hot air zone and the lowest point of the hot air zone. At the same time, the rotating speed of the main air blower component can be increased to press down the hot air zone, so that the height position of the hot air zone is further reduced and the lowest point of the hot air zone is further reduced.

[0100] And since the operation frequency of the compressor changes, the distance of the hot air zone relative to the main machine 10 also changes. Specifically, when the operation frequency of the compressor is reduced, the hot air zone is relatively far away from the main machine 10. At this time, the sub-machine 20 can be controlled to move to a position corresponding to a new hot air zone formed after the operation frequency of the compressor is adjusted. The sub-machine 20 moves in a direction away from the main machine 10, so that the sub-machine 20 moves to the new hot air zone. Since the height position of the new hot air zone is relatively low, the sub-machine 20 can effectively utilize more heat of the hot air zone, so that the sub-machine 20 can transport more heat of the main machine 10 to the position of the user, thereby further rapidly increasing the temperature of the surrounding area of the user or the body surface temperature of the user.

[0101] In the above embodiment of adjusting the operation frequency of the compressor and adjusting the rotating speed of the main air blower component, if the air supply temperature of the main machine 10 is not greater than the set air supply temperature, it indicates that the temperature of the hot air zone is relatively low. Although the height position of the hot air zone is relatively low and the lowest point of the hot air zone is relatively low at this time, the sub-machine 20 can utilize more heat of the hot air zone. However, since the temperature of the hot air zone is relatively low, the temperature of the heat utilized by the sub-machine 20 is relatively low, so that the temperature of the surrounding area of the user or the body surface temperature of the user cannot be effectively and rapidly increased. At this time, the operation frequency of the compressor can be increased, so that the air supply temperature of the main machine 10 is slightly increased, thereby increasing the temperature of the hot air zone. At the same time, the rotating speed of the main air blower component can be reduced, so that the air supply of the main machine 10 is more concentrated, and more heat of the air supply port of the main machine 10 is concentrated in the hot air zone.

[0102] After the temperature of the hot air zone is increased, the distance of the hot air zone relative to the main machine 10 is also changed, specifically, the hot air zone is relatively closer to the main machine 10, at this time, the sub-machine 20 can be controlled to move to the position corresponding to the new hot air zone formed after the operating frequency of the compressor is adjusted, and the sub-machine 20 moves towards the direction close to the main machine 10, so that the sub-machine 20 moves to the new hot air zone. Although the height position of the hot air zone and the lowest point of the hot air zone are relatively raised, the overall temperature of the hot air zone is taken into account, and when the temperature of the hot air zone is relatively high, the height position of the hot air zone is relatively low, and the lowest point of the hot air zone is relatively low, the sub-machine 20 can effectively relay more heat of the hot air zone, and the temperature of the hot air zone is relatively high, so that the sub-machine 20 can transport more heat of the main machine 10 to the position of the user, and further rapidly increase the temperature of the surrounding area of the user or the body surface temperature of the user.

[0103] In some optional embodiments of the present application, the adjusting of the operating parameters of the main machine 10 according to the blowing temperature of the main machine 10 can include:

[0104] If the blowing temperature of the main machine 10 is greater than the set blowing temperature, the speed of the main air blower component is preferentially adjusted, and if both the speed of the main air blower component and the operating frequency of the compressor can be adjusted, the speed of the main air blower component is preferentially adjusted, wherein the preferential adjustment of the speed of the main air blower component is specifically increasing the speed of the main air blower component, so that the height position of the hot air zone is lowered when the temperature of the hot air zone is relatively high and the height position of the hot air zone is lowered by increasing the speed of the main air blower component, so that the sub-machine 20 can relay more heat of the hot air zone and the temperature of the hot air zone is relatively high, so that the sub-machine 20 can transport more heat to the user and rapidly increase the temperature of the surrounding area of the user or the body surface temperature of the user, and when the speed of the main air blower component is increased to the highest speed and cannot be continuously increased, the operating frequency of the compressor can be reduced, so that the height position of the hot air zone is lowered, and the sub-machine 20 is controlled to move to the position corresponding to the new hot air zone, so that the sub-machine 20 can transport more heat to the user and rapidly increase the temperature of the surrounding area of the user or the body surface temperature of the user;

[0105] If the supply air temperature of the main machine 10 is not greater than the set supply air temperature, the operating frequency of the compressor is preferentially adjusted, and if the rotating speed of the main fan component and the operating frequency of the compressor can both be adjusted, the operating frequency of the compressor is preferentially adjusted, specifically, the operating frequency of the compressor is increased, so that the temperature of the hot air zone is increased, and the sub-machine 20 is controlled to move to a position corresponding to a new hot air zone, so that the sub-machine 20 relays from the hot air zone to hot air with a higher temperature, so that the sub-machine 20 relays more heat of the hot air zone and the temperature of the hot air zone is higher, so that the sub-machine 20 delivers more heat to the user, rapidly increases the temperature of the surrounding area of the user or the body surface temperature of the user, and when the operating frequency of the compressor is increased to the highest operating frequency and cannot be continuously increased, the rotating speed of the main fan component is decreased, so that the heat delivered from the supply air outlet of the main machine 10 is more concentrated in the hot air zone, so that the sub-machine 20 delivers more heat to the user, rapidly increases the temperature of the surrounding area of the user or the body surface temperature of the user.

[0106] Optionally, the set supply air temperature can be in a range of 33-38℃, for example, the set supply air temperature can be 33℃, 34℃, 35℃, 36℃, 37℃, 38℃, etc.

[0107] According to some embodiments of the present application, the control of the sub-machine 20 to supply air towards the user can further include:

[0108] The distance between the user and the sub-machine 20 is collected, which can be measured by an infrared camera on the sub-machine 20.

[0109] According to the distance between the user and the sub-machine 20, the sub-machine 20 is controlled to switch to a corresponding supply air mode.

[0110] In this way, according to the distance between the user position and the sub-machine 20, the sub-machine 20 is switched to a corresponding supply air mode, and in different distances, the supply air mode of the sub-machine 20 is also different, so that the sub-machine 20 can deliver the heat relayed from the main machine 10 to the position of the user, and the hot air delivered by the sub-machine 20 can be relatively soft when reaching the user, reducing the discomfort caused by the sub-machine 20 supplying air towards the user.

[0111] For example, in some optional embodiments of the present application, referring to Figure 4 and Figure 5 , the sub-machine 20 can include a first fan 231 and a second fan 232, the first fan 231 is a centrifugal fan, and the second fan 232 is an axial fan, a cross-flow fan or a contra-rotating fan, different fans are started in different supply air modes, so that the supply air distance and the supply air effect in different supply air modes are different, so that different fans can be started to make the sub-machine 20 supply air towards the user in different supply air modes when the distance between the user position and the sub-machine 20 is different.

[0112] For example, when the distance between the user and the slave unit 20 is large, only the first fan 231 can be turned on. The first fan 231 is a centrifugal fan. The centrifugal fan has a large air delivery speed and a relatively concentrated air delivery direction, which makes the air delivery distance of the first fan 231 longer. The slave unit 20 can relay the heat to the user's location. Moreover, during the delivery process, due to the large delivery distance, the hot air reaching the user can be relatively gentle.

[0113] For example, when the distance between the user and the sub-unit 20 is small, only the second fan 232 can be turned on. The second fan 232 can be an axial fan, a cross-flow fan, or a counter-rotating fan. When the second fan 232 is a counter-rotating fan, it includes two coaxial and oppositely arranged axial impellers. The second fan 232 can use a gentle air delivery method. Compared with centrifugal fans, axial fans and cross-flow fans have lower air delivery speeds and larger air delivery angles, resulting in more diffused airflow. This makes the air delivery distance of the second fan 232 larger, so that the sub-unit 20 can deliver the relayed heat to the user's location, and the hot air reaching the user can be relatively gentle.

[0114] For example, if the second fan 232 is located downstream of the first fan 231, and the distance between the user's location and the sub-unit 20 is small, the first fan 231 and the second fan 232 can be turned on simultaneously. The air from the first fan 231 is softened by the second fan 232, which can also make the air delivery distance of the sub-unit 20 smaller. In this way, the sub-unit 20 can deliver the relay heat to the user's location, and the hot air reaching the user can be relatively gentle.

[0115] It should be explained that the phrase "the second fan 232 is located downstream of the first fan 231" in this invention refers to the direction of airflow in the sub-unit 20.

[0116] According to some optional embodiments of the present invention, refer to Figure 6 Based on the distance between the user and the slave unit 20, the slave unit 20 is controlled to switch to the corresponding air supply mode, which may include:

[0117] When the distance between the user and the sub-unit 20 is greater than the preset distance, it means that the distance between the user and the sub-unit 20 is too large. Control the sub-unit 20 to switch to the first air supply mode. In the first air supply mode, the sub-unit 20 can achieve long-distance transmission, thereby delivering the relayed heat to the user's location.

[0118] When the distance between the user and the sub-machine 20 is not greater than the preset distance, it indicates that the distance between the user and the sub-machine 20 is small, and the sub-machine 20 is controlled to switch to the second air supply mode. The air supply distance of the first air supply mode is greater than that of the second air supply mode, and the sub-machine 20 can realize close distance delivery in the second air supply mode, so that the heat relayed by the sub-machine 20 can be delivered to the position of the user, and the discomfort caused by the close distance direct blowing of the sub-machine 20 to the user can be avoided.

[0119] Optionally, the preset distance can be determined according to the maximum air supply distance of the sub-machine 20 in the second air supply mode. For example, when the sub-machine 20 includes the first fan 231 and the second fan 232 described above, only the first fan 231 is started to work when the sub-machine 20 is in the first air supply mode, only the second fan 232 is started to work or the first fan 231 and the second fan 232 are started to work at the same time (in the case that the second fan 232 is located at the downstream side of the first fan 231) when the sub-machine 20 is in the second air supply mode.

[0120] According to some optional embodiments of the present application, the control of the sub-machine 20 to switch to the corresponding air supply mode according to the distance between the user and the sub-machine 20 can further include:

[0121] According to the distance between the user position and the sub-machine 20, the rotating speed of the sub-machine 20 in the corresponding air supply mode is determined. In the above, when the size relationship between the distance between the user position and the sub-machine 20 and the preset distance is judged, and the sub-machine 20 is controlled to switch to the corresponding air supply mode to supply air, the rotating speed of the sub-machine 20 in the air supply mode can be further determined according to the distance between the user and the sub-machine 20. In this way, when the sub-machine 20 switches to the corresponding air supply mode, the rotating speed of the sub-machine 20 is further optimized to make the rotating speed of the sub-machine 20 in the air supply mode more matched with the distance between the user position and the sub-machine 20, so that the hot air delivered by the sub-machine 20 reaches the user with a suitable speed and wind power, which not only can quickly adjust the temperature of the user's body surface and the temperature of the area near the user, but also can ensure that the hot air delivered by the sub-machine 20 reaches the user more gently, further improving the comfort.

[0122] Optionally, the hot air delivered by the sub-machine 20 can reach the user, and the user's body surface wind speed can be 0.2m / s-0.5m / s, for example, the user's body surface wind speed can be 0.3m / s, so that the temperature of the user's body surface and the temperature of the area near the user can be adjusted more quickly, and the hot air delivered by the sub-machine 20 reaches the user more gently, further improving the comfort.

[0123] For example, when the distance between the user and the sub-machine 20 is greater than the first preset distance, the sub-machine 20 is controlled to switch to the first air supply mode, and the rotating speed of the sub-machine 20 is determined according to the distance between the user and the sub-machine 20. When the sub-machine 20 comprises the first fan 231 and the second fan 232, only the first fan 231 works in the first air supply mode, and the rotating speed of the first fan 231 can be determined according to the distance between the user and the sub-machine 20.

[0124] For another example, when the distance between the user and the sub-machine 20 is not greater than the first preset distance, the sub-machine 20 is controlled to switch to the second air supply mode, and the rotating speed of the sub-machine 20 is determined according to the distance between the user and the sub-machine 20. When the sub-machine 20 comprises the first fan 231 and the second fan 232, only the second fan 232 works in the second air supply mode, and the rotating speed of the second fan 232 can be determined according to the distance between the user and the sub-machine 20; or, when the sub-machine 20 comprises the first fan 231 and the second fan 232, the second fan 232 is located at the downstream side of the first fan 231, the first fan 231 and the second fan 232 both work in the second air supply mode, and the rotating speeds of the first fan 231 and the second fan 232 can be determined according to the distance between the user and the sub-machine 20, and the rotating speed of the second fan 232 can be adjusted according to the distance between the user and the sub-machine 20.

[0125] In some optional embodiments of the present application, the sub-machine 20 is controlled to switch to the corresponding air supply mode according to the distance between the user and the sub-machine 20, and the method further comprises:

[0126] The initial rotating speed of the sub-machine 20 in the corresponding air supply mode is corrected according to the initial temperature of the indoor environment. The initial rotating speed of the sub-machine 20 can be corrected by adding the initial value of the indoor environment temperature, and the rotating speed of the sub-machine 20 is corrected according to the initial value of the indoor environment temperature. In this way, the initial rotating speed of the sub-machine 20 is determined not only by considering the distance between the sub-machine 20 and the user, but also by considering the initial value of the indoor environment temperature. When the distance between the sub-machine 20 and the user is the same, if the initial value of the indoor environment temperature is different, the initial rotating speed of the sub-machine 20 is relatively large when the initial value of the indoor environment temperature is low, compared with the case that the initial value of the indoor environment temperature is high. In this way, the temperature of the user's body surface and the temperature of the area near the user can be rapidly increased when the indoor environment temperature is low.

[0127] According to some embodiments of the present application, with reference to Figure 6 , the control method of the air conditioner comprises:

[0128] After the sub-machine 20 moves to the air supply range of the main machine 10 to relay the heat delivery of the main machine 10 to the position of the user, the user body surface temperature or the temperature of the user surrounding area can be collected to determine whether the user body surface temperature is not less than the first preset temperature or the temperature of the user surrounding area is not less than the first set temperature, which indicates that the user demand heat basically reaches the demand at this time.

[0129] The main machine 10 can keep the current state, and the operating parameters of the main machine 10 can remain unchanged, and the operating parameters of the main machine 10, such as the operating frequency of the compressor or the rotating speed of the main fan component, do not need to be adjusted. The sub-machine 20 keeps the current state, and the operating parameters of the sub-machine 20 can remain unchanged. Since the operating parameters of the main machine 10 are not changed, the hot air area of the main machine 10 relative to the position of the main machine 10 is also basically unchanged, so that the sub-machine 20 can keep the current position and continue to relay the heat of the main machine 10 to the user to make the temperature of the user surrounding area remain in the comfortable range.

[0130] In some optional embodiments of the present application, the control method of the air conditioner further comprises:

[0131] In the process of keeping the current state of the main machine 10 and the sub-machine 20, the temperature of the user surrounding area is continuously collected to determine whether the temperature of the user surrounding area is greater than a second set temperature. The second set temperature is greater than the first set temperature, and the second set temperature can be 20-25℃, for example, the second set temperature can be 20℃, 21℃, 22℃, 23℃, 24℃, 25℃, etc. It indicates that the overall heat can meet the user demand, and the temperature of the user surrounding area not only reaches the comfortable temperature but also is relatively high. At this time, the user can have a dry feeling.

[0132] The humidification module of the air supply processing unit is turned on to humidify the indoor air, realize microclimate regulation, and further improve the comfort of the user.

[0133] In the process of keeping the current state of the main machine 10 and the sub-machine 20, the temperature of the user surrounding area is continuously collected to determine whether the temperature of the user surrounding area is greater than a second set temperature. The main machine 10 and the sub-machine 20 still keep the current state, and the humidification module is not turned on.

[0134] Further, the control method of the air conditioner further comprises:

[0135] In the process of humidification of the humidification module, the indoor environment humidity is collected.

[0136] When it is determined that the indoor environment humidity is greater than the set humidity, the humidifying module is turned off. Thus, when the indoor environment humidity reaches the user demand, the humidifying module can be turned off in time, so that the temperature and humidity of the area around the user are kept within the comfortable range.

[0137] In some embodiments of the present application, when the humidifying module humidifies the indoor environment humidity to be greater than the set humidity, the humidifying module is turned off, and the slave machine 20 can be moved out of the air supply range of the master machine 10, so that the slave machine 20 supplies air in the non-user direction, and the air inlet area of the slave machine 20 can be adjacent to the air supply range of the master machine 10, for example, the air inlet area of the slave machine 20 can be adjacent to the hot air zone of the master machine 10. In this way, when the master machine 10 is in heating operation and the slave machine 20 supplies air in the non-user direction, the air inlet area of the slave machine 20 forms a negative pressure zone, under the action of the pressure difference, the airflow of the hot air zone of the master machine 10 flows to the air inlet area of the slave machine 20, and because the height position of the air inlet area of the slave machine 20 is relatively low, it is beneficial to flow the hot air of the hot air zone out of the air supply range of the master machine 10 and to flow the hot air of the hot air zone downward, which is beneficial to the uniformization of the temperature of the entire indoor environment. At the same time, the slave machine 20 sends the airflow sucked from the air inlet area out of the air outlet to a position farther away from the master machine 10, so that the heat of the master machine 10 can be delivered to a position farther away from the master machine 10 in the indoor space, which is further beneficial to the uniformization of the temperature of the entire indoor environment.

[0138] Hereinafter, a control method of an air conditioner according to an embodiment of the present application will be described with reference to the accompanying drawings. Figure 6 A control method of an air conditioner according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0141] S02, it is determined whether the return air temperature of the master machine 10 is greater than the set return air temperature;

[0148] S21, adjust the operating parameters of the main machine 10, and correspondingly adjust the position of the sub-machine 20, and continue to identify the temperature of the area around the user.

[0149] If the temperature of the area around the user is not less than the first set temperature, the following steps S31 and S32 are performed:

[0150] S31, the main machine 10 and the sub-machine 20 both maintain the current state;

[0151] S32, determine whether the temperature of the area around the user is greater than a second set temperature.

[0152] If the temperature of the area around the user is not greater than the second set temperature, the above step S31 is continued to be performed; if the temperature of the area around the user is greater than the second set temperature, the following steps S41 and S42 are performed.

[0156] The air conditioner according to the embodiment of the present application, when the user is not in the air supply range of the main machine 10, moves the sub-machine 20 to the air supply range of the main machine 10 to relay the heat of the main machine 10, and delivers the heat of the main machine 10 to the position of the user, so as to quickly adjust the user body surface temperature and the temperature of the area around the user, thereby when the user is not in the air supply range of the main machine 10 or is far away from the main machine 10, the temperature of the area around the user and the user body surface temperature can be quickly raised, the temperature of the area around the user quickly reaches the comfortable temperature range, and more and higher demands of the user are met; and when the user body surface temperature or the temperature of the area around the user does not reach the demand of the user, the operating parameters of the main machine 10 are adjusted, so that the sub-machine 20 can relay more heat of the main machine 10 to the user, thereby the temperature of the area around the user and the user body surface temperature can be more effectively adjusted.
