[0053] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0054] Reference below Figures 1-6 A method for controlling an air conditioner according to an embodiment of the present invention is described.

[0055] like Figure 1-Figure 3 As shown, a method for controlling an air conditioner according to a first embodiment of the present invention is provided, wherein the air conditioner may include a main unit 10 and a slave unit 20, and the slave unit 20 may be detachably mounted on the main unit 10. For example, the slave unit 20 may be detachably connected to the main unit 10. When the slave unit 20 needs to be separated from the main unit 10, the slave unit 20 may be removed from the main unit 10; when the slave unit 20 needs to be stored in the main unit 10, the slave unit 20 may be mounted on the main unit 10. When the slave unit 20 is mounted on the main unit 10, the slave unit 20 may be mounted outside the main unit 10 or inside the main unit 10.

[0056] For example, the main unit 10 may have an installation cavity 13 formed therein for accommodating the sub-unit 20. The sub-unit 20 is installed in the installation cavity 13. A separation opening 14 may be formed on one side of the installation cavity 13. The sub-unit 20 can be installed into the main unit 10 or removed from the main unit 10 to be separated from the main unit 10 through the separation opening 14. A separation door 15 for opening and closing the separation opening 14 may be provided at the separation opening 14. The separation door 15 may be detachably mounted to the separation opening 14. When the separation door 15 is removed from the separation opening 14, the separation door 15 opens the separation opening 14; when the separation door 15 is mounted to the separation opening 14, the separation door 15 closes the separation opening 14. The separation door 15 may also be rotatably mounted to the separation opening 14. The separation door 15 opens and closes the separation opening 14 by rotating the separation door 15.

[0057] The main unit 10 may include a main housing 11 and a heat exchange and air supply unit. The heat exchange and air supply unit is disposed within the main housing 11 and is formed with a return air vent 111 and an air supply vent. The heat exchange and air supply unit may include a heat exchanger component and a main blower component. When the main unit 10 is in operation, the main blower component drives external air into the main housing 11 through the return air vent 111. After exchanging heat with the heat exchanger component, the air is blown out into the room through the air supply vent, thereby regulating the indoor ambient temperature and achieving cooling / heating.

[0058] Optionally, the main housing 11 may define the aforementioned installation cavity 13 and a receiving cavity. The installation cavity 13 and the receiving cavity may be separated. For example, a partition may be provided in the main housing 11 to separate the space within the main housing 11 into the installation cavity 13 and the receiving cavity. The heat exchange and air supply unit may be provided in the receiving cavity, and the slave unit 20 may be installed in the installation cavity 13.

[0059] The air conditioner can be a split-type air conditioner, for example, a split floor-standing air conditioner or a split wall-mounted air conditioner. When the air conditioner is a split-type air conditioner, the air conditioner includes an indoor air conditioner unit 100 and an outdoor air conditioner unit. The indoor air conditioner unit 100 includes the aforementioned main unit 10 and sub-unit 20. For example, when the air conditioner is a split floor-standing air conditioner, the indoor air conditioner unit 100 includes the aforementioned main unit 10 and sub-unit 20. The main housing 11 of the main unit 10 defines a receiving chamber and an installation chamber 13 spaced apart from each other. The installation chamber 13 is located below the receiving chamber. The heat exchange and air supply unit is installed in the receiving chamber, and the sub-unit 20 can be installed in the installation chamber 13. Thus, the installation chamber 13 for accommodating the sub-unit 20 is positioned at a lower position, making it easier to separate the sub-unit 20 from the main unit 10 or install it into the main unit 10.

[0060] The sub-unit 20 may include a sub-housing 21 and an air supply processing unit. The air supply processing unit is disposed within the sub-housing 21. The sub-housing 21 is formed with an air inlet and an air outlet. The air supply processing unit may include a sub-blower component 23. The sub-unit 20 itself may not have heating / cooling functions. When the sub-unit 20 is in operation, the sub-blower component 23 operates, driving external air into the sub-housing 21 through the air inlet and then blowing it out into the room through the air outlet. The air supply processing unit may also include a humidification module, giving the sub-unit 20 a humidification function, thereby humidifying the indoor air and improving the indoor air quality. Furthermore, when the sub-unit 20 is moved near a user, the sub-unit 20 can quickly humidify the air near the user.

[0061] Optionally, the humidification module may include a wet membrane assembly and a water pump for spraying water onto the wet membrane assembly. The start and stop of the humidification module may be conveniently controlled by controlling the start and stop of the water pump.

[0062] Optionally, the air supply processing unit may further include a purification module, enabling the slave 20 to have both humidification and purification functions. This allows the slave 20 to humidify and / or purify the indoor air, improving the indoor air quality. Furthermore, when the slave 20 is moved near a user, it can quickly humidify and / or purify the air near the user.

[0063] Optionally, the main body of the slave 20 may be roughly a rectangular parallelepiped (see Figure 1 ), or it can be roughly cylindrical (see Figure 2 and Figure 3 ).

[0064] The slave 20 and the main unit 10 can communicate with each other. The slave 20 can transmit collected information to the main unit 10, and its own operating status can be transmitted to the main unit 10. The main unit 10 can also transmit collected information to the slave 20, and its own operating status can be transmitted to the slave 20. When the slave 20 is detached from the main unit 10, the slave 20 can be movable. For example, the base of the slave 20 can be provided with wheels 22, which can be universal wheels, allowing the slave 20 to move in any direction. For example, when the slave 20 is detached from the main unit 10 and placed on the ground, the slave 20 can detect the user's location and automatically move to the user's vicinity based on the user's location to provide air to the user or humidify / purify the air near the user. Of course, the slave 20 can also be moved to other locations based on specific user instructions. The movement of the slave 20 within the room can expand the air supply range of the main unit 10, thereby enhancing the flow of indoor air and thus promoting a uniform indoor ambient temperature. After the main unit 10 is turned on, the sub-unit 20 can work according to user instructions or set programs, making the operation of the entire air conditioner more flexible and the functions more diverse, meeting more needs of users.

[0065] The host 10 can operate independently. The slave 20 can be completely controlled by the host 10. If the host 10 is not turned on, the slave 20 cannot operate independently. The slave 20 can also operate independently without being controlled by the host 10. For example, when the host 10 is not turned on, the slave 20 can operate independently. When both the host 10 and the slave 20 are turned on, communication can be established between the host 10 and the slave 20, facilitating information transfer between the host 10 and the slave 20, thereby facilitating better control of the slave 20 and the host 10.

[0066] Optionally, the air inlet of the slave 20 is located below the air outlet of the slave 20. After the main unit 10 is turned on, the slave 20 can be moved to a set position, for example, the slave 20 can be moved near the user. Since the air inlet of the slave 20 is located at a lower position, the slave 20 can draw air from a lower position into the slave 20 and blow it upward, which is beneficial to enhance indoor air flow and thus help to even out the indoor ambient temperature.

[0067] For example, when the air conditioner is in cooling mode, the cold air flows downward due to its own gravity. The slave unit 20 can transport the cooler air from the lower level upward, creating air disturbance. By moving the cooler air upward, the air temperature at the upper level drops, making the air flow at the upper level more fluid. A negative pressure zone is formed near the air inlet of the slave unit 20, forcing the warmer air at the upper level to flow downward, causing the air temperature at the lower level to rise. This accelerates and strengthens the flow of indoor air, thereby promoting uniform indoor temperature. When the slave unit 20 is moved near the user, the temperature of the air near the user is more uniform from top to bottom, improving comfort.

[0068] For example, when the air conditioner is heating, the hot air rises due to its own gravity. The slave unit 20 can transport the cooler air from the lower level to the upper level, creating air disturbance. By moving the cooler air upward, the air temperature at the upper level drops, making the air flow at the upper level more fluid. A negative pressure zone forms near the air inlet of the slave unit 20, forcing the cooler air at the upper level to flow downward, causing the air temperature at the lower level to rise. This accelerates and strengthens the flow of indoor air, thereby facilitating the uniformity of the indoor ambient temperature. When the slave unit 20 moves near the user, the temperature of the air near the user is made more uniform from top to bottom, improving comfort. Furthermore, the temperature migration around the slave unit 20 raises the temperature at the lower level around the user, which helps to increase the temperature of the lower limbs, such as the feet, making the user's lower limbs feel warmer.

[0069] The control methods of the air conditioner include:

[0070] Control the host 10 to start and run, for example, the host 10 can be controlled to run heating or cooling, thereby adjusting the indoor ambient temperature;

[0071] The user's location can be collected by the main unit 10 or the slave unit 20. For example, the user's location can be collected by an infrared camera on the slave unit 20 or the main unit 10 to provide a basis for the subsequent movement of the slave unit 20. The user's location can be collected immediately after the main unit 10 is turned on, or after the main unit 10 has been running in heating or cooling mode for a period of time.

[0072] After the user's location is collected, the handset 20 is controlled to automatically move according to the collected user's location. The handset 20 may be controlled to move to the area surrounding the user, so that the handset 20 stops moving after moving to the area surrounding the user. Of course, when the handset 20 is already in the area surrounding the user, the handset 20 may remain stationary.

[0073] The temperature and humidity of the area around the user are collected. For example, the temperature of the area around the user can be collected by a temperature sensor on the slave 20, and the humidity of the area around the user can be collected by a humidity sensor on the slave 20. After the slave 20 moves to the area around the user, the temperature and humidity of the area around the user are collected by the slave 20, which can improve the accuracy of the collected results.

[0074] After the slave unit 20 obtains the temperature and humidity of the area around the user, the slave unit 20 may be controlled to operate according to the temperature and humidity of the area around the user.

[0075] The operation of the slave unit 20 includes one of air supply by the slave unit 20 and air humidification by the slave unit 20 .

[0076] For example, based on the temperature and humidity of the area surrounding the user, the handset 20 can be activated to deliver air, thereby rapidly adjusting the temperature of the area surrounding the user. When the handset 20 delivers air directly toward the user, it can rapidly increase or decrease the body's surface temperature, rapidly adjusting the temperature of the area surrounding the user to a comfortable level. When the handset 20 delivers air toward areas not surrounding the user, it can enhance airflow in the area surrounding the user. Combined with the negative pressure of the handset 20's inlet, it draws the upper airflow downward, achieving a temperature shift in the area surrounding the handset 20, rapidly reaching a comfortable level. Furthermore, because the handset 20 facilitates air flow throughout the room, it also helps to even out the indoor ambient temperature, further enhancing the comfort of air conditioner use. Regardless of whether the handset 20 delivers air toward the user, rapid temperature adjustment can be achieved when the handset 20 is located near the user and delivering air.

[0077] For another example, based on the temperature and humidity of the area surrounding the user, the slave unit 20 can be activated to deliver air, and the humidification module of the slave unit 20 can be activated to deliver humidification, thereby rapidly adjusting the temperature and humidity of the area surrounding the user. When the slave unit 20 delivers air directly toward the user, it can rapidly increase or decrease the body surface temperature, rapidly adjust the temperature of the area surrounding the user, and bring the temperature and humidity of the area surrounding the user to a comfortable range. When the slave unit 20 delivers air toward non-user areas, it can enhance airflow in the area surrounding the user. Combined with the negative pressure of the inlet air of the slave unit 20, it attracts the upper airflow downward, achieving a temperature shift in the area surrounding the slave unit 20, and rapidly bringing the temperature of the area surrounding the user to a comfortable range. Furthermore, since the operation of the slave unit 20 promotes air flow throughout the room, it also helps to uniformize the indoor ambient temperature, further improving the comfort of air conditioner use, and achieving humidity regulation of both the area surrounding the user and the entire indoor environment.

[0078] Regardless of whether the sub-unit 20 is supplying air toward the user, when the sub-unit 20 is located in the area around the user and is supplying air, the temperature of the area around the user can be quickly adjusted, and the humidity of the area around the user and the indoor environment can be adjusted, so that the temperature and humidity of the area around the user can be quickly adjusted to a comfortable range, thereby improving comfort and meeting the user's higher needs.

[0079] For example, when the air conditioner is in heating mode, after the sub-unit 20 moves to the area around the user, the sub-unit 20 collects the temperature and humidity of the area around the user. When the temperature in the area around the user is low, the sub-unit 20 can be made to blow air toward the user to quickly increase the user's body surface temperature and the temperature of the area around the user. The sub-unit 20 can also be made to blow air toward the non-user area. For example, the sub-unit 20 can be made to blow air toward the return air outlet 111 of the main unit 10, which is equivalent to increasing the return air volume of the main unit 10 and improving the heating efficiency of the main unit. Moreover, it can not only accelerate the air flow in the area around the user, but also accelerate and strengthen the circulation of indoor air, and can also relatively quickly increase the temperature of the area around the user.

[0080] When the temperature in the area around the user reaches a relatively comfortable range, the sub-unit 20 can be made to supply air toward the non-user area to avoid the discomfort caused by hot air blowing directly on the human body. For example, the sub-unit 20 can be made to supply air toward the return air outlet 111 of the main unit 10 to accelerate and strengthen the circulation of indoor air, thereby accelerating the uniformity of the indoor ambient temperature and further improving the comfort level. The sub-unit 20 can also be made to supply air toward the air supply outlet of the main unit 10, so that the air blown out by the sub-unit 20 can counteract the strong wind sent out from the air supply outlet of the main unit 10, avoiding the discomfort caused by direct blowing from the main unit 10.

[0081] When the humidity in the area around the user is low, the humidification module of the slave unit 20 can be turned on to adjust the humidity in the area around the user. In this way, the temperature and humidity in the area around the user can be quickly adjusted to a comfortable range based on the temperature and humidity in the area around the user, thereby improving comfort and meeting the user's higher needs.

[0082] For example, when the air conditioner is in cooling mode, after the slave unit 20 moves to the area around the user, the slave unit 20 collects the temperature and humidity of the area around the user. When the temperature in the area around the user is high, the slave unit 20 can be made to blow air toward the user to quickly lower the user's body surface temperature and the temperature of the area around the user. Alternatively, the slave unit 20 can be made to blow air toward non-user areas. For example, the slave unit 20 can be made to blow air toward the return air outlet 111 of the main unit 10, which is equivalent to increasing the return air volume of the main unit 10 and improving the cooling efficiency of the main unit. Furthermore, it can not only accelerate the air flow in the area around the user, but also accelerate and strengthen the circulation of indoor air, and can also effectively reduce the temperature of the area around the user more quickly.

[0083] When the temperature in the area around the user reaches a relatively comfortable temperature range, the sub-unit 20 can be made to supply air toward the non-user area to avoid the discomfort caused by cold air blowing directly on the human body. For example, the sub-unit 20 can be made to supply air toward the return air outlet 111 of the main unit 10 to accelerate and strengthen the circulation of indoor air, thereby accelerating the uniformity of the indoor ambient temperature and further improving the comfort level. The sub-unit 20 can also be made to supply air toward the air supply outlet of the main unit 10, so that the air blown out by the sub-unit 20 can counteract the strong wind sent out from the air supply outlet of the main unit 10, avoiding the discomfort caused by direct blowing from the main unit 10.

[0084] When the humidity in the area around the user is low, the humidification module of the slave unit 20 can be turned on to adjust the humidity in the area around the user. In this way, the temperature and humidity in the area around the user can be quickly adjusted to a comfortable range based on the temperature and humidity in the area around the user, thereby improving comfort and meeting the user's higher needs.

[0085] After the host 10 is turned on, the sub-machine 20 can be controlled to move to the area around the user, and the temperature and humidity of the area around the user can be accurately collected. The operation of the sub-machine 20 can be controlled according to the temperature and humidity of the area around the user, which can enhance the airflow in the area around the user, so that the temperature in the area around the user quickly reaches a more comfortable temperature, and the humidity in the area around the user can be quickly adjusted, so that the temperature and humidity in the area around the user can be adjusted to a comfortable range more quickly, thereby improving comfort and meeting the user's higher needs.

[0086] Optionally, the "user surrounding area" can be determined based on a negative pressure area formed when the handset 20 is in operation. When the handset 20 is in operation, a negative pressure area is formed near the air inlet of the handset 20. When the handset 20 is located in the user surrounding area, the size of the user surrounding area can be determined based on the size of the negative pressure area formed when the handset 20 is in operation, so that the user can be located in or near the negative pressure area of ​​the handset 20. In this way, when the handset 20 is in operation, the handset 20 can enhance airflow in the user surrounding area, thereby facilitating rapid temperature adjustment in the user surrounding area, allowing the temperature in the user surrounding area to be quickly adjusted to a relatively comfortable temperature range, particularly the temperature in the lower part of the user surrounding area to be adjusted to a comfortable temperature range.

[0087] Optionally, the "user surrounding area" can be within a range of radius a centered on the user, where a is in the range of 1 to 2 meters. This allows the user to be located in or near the handset 20. When the handset 20 is operating, it can enhance the airflow in the user surrounding area, thereby facilitating rapid temperature adjustment of the user surrounding area, allowing the temperature in the user surrounding area to be quickly adjusted to a more comfortable temperature range, particularly adjusting the temperature in the lower portion of the user surrounding area to a comfortable temperature range; and avoiding discomfort caused by the handset 20 being too close to the user. Furthermore, the range of a is 1.5 to 2 meters, for example, a can be 1.5 meters, 1.8 meters, 2 meters, and so on.

[0088] For example, in some specific embodiments of the present invention, the size of the negative pressure zone formed when the handset 20 rotates at its highest speed is used to determine the size of the area surrounding the user. For example, when the handset 20 rotates at its highest speed, a negative pressure zone is formed near the air inlet of the handset 20 at a distance a from the handset 20. When the handset 20 is located in the area surrounding the user, the handset 20 can be located within a range of a radius a centered on the user, where a is in the range of 1 to 2 meters. This allows the user to be located near the negative pressure zone of the handset 20, thereby facilitating rapid adjustment of the temperature and humidity in the area surrounding the user, and avoids discomfort caused by the handset 20 being too close to the user.

[0089] In some embodiments of the present invention, the handset 20 can also rotate, and the rotation of the handset 20 can adjust and change the horizontal airflow direction of the handset 20. For example, the handset 20 can include a base and a handset body disposed on the base. The handset body includes the aforementioned airflow processing unit. The bottom of the base can be provided with wheels 22 to enable movement of the handset 20. The handset body can rotate relative to the base. The handset 20 can include a drive mechanism for driving the handset body to rotate relative to the base. The rotation axis of the handset body can extend in the vertical direction, and the handset body can rotate 360 ​​degrees horizontally relative to the base. By controlling the drive mechanism to drive the handset body to rotate so that the air outlet of the handset 20 faces the user or non-user area, the horizontal airflow direction of the handset 20 can be conveniently adjusted and changed.

[0090] According to the control method of the air conditioner of an embodiment of the present invention, after the main unit 10 is turned on, the sub-unit 20 can be controlled to move to the area around the user, and the temperature and humidity of the area around the user can be accurately collected. The operation of the sub-unit 20 is controlled according to the temperature and humidity of the area around the user, and the air flow in the area around the user can be enhanced, so that the temperature in the area around the user quickly reaches a more comfortable temperature, and the humidity in the area around the user can be quickly adjusted, so that the temperature and humidity in the area around the user can be adjusted to a comfortable range more quickly, thereby improving comfort and meeting higher needs of users.

[0091] According to some embodiments of the present invention, referring to Figure 6 , according to the temperature and humidity of the area around the user, controlling the operation of the slave 20 may include:

[0092] Determining that the humidity in the area around the user is higher than the preset humidity indicates that the humidity in the area around the user is high, and also indicates that the humidity in the entire indoor environment is also high. At this time, the humidification module of the slave 20 is not turned on;

[0093] The sub-machine 20 is controlled to supply air toward the return air outlet 111 of the main machine 10. When the sub-machine 20 supplies air, since the sub-machine 20 is located in the area around the user, the sub-machine 20 can form a negative pressure area in the area around the user, so that the sub-machine 20 can enhance the air flow in the area around the user. The sub-machine 20 inhales the air around the user and discharges it to the return air outlet 111 of the main machine 10. The main machine 10 inhales the air delivered by the sub-machine 20 into the main machine 10 through the return air outlet 111, and then discharges it into the room from the air supply outlet of the main machine 10. This can further enhance the air circulation and flow in the area around the user and the entire indoor environment, which can reduce the discomfort caused by excessive air humidity to a certain extent, and is also conducive to reducing humidity, thereby improving the user's comfort, and is also conducive to the rapid uniformity of the indoor environmental temperature.

[0094] According to some embodiments of the present invention, referring to Figure 6 , according to the temperature and humidity of the area around the user, controlling the operation of the slave 20 may include:

[0095] When the host 10 is in cooling operation, if it is determined that the temperature of the area around the user is higher than the first preset temperature, it means that the temperature of the area around the user is relatively high and needs to be further quickly cooled down. The first preset temperature may be a temperature set by the user according to needs. Alternatively, when the host 10 is in heating operation, if it is determined that the temperature of the area around the user is lower than the second preset temperature, it means that the temperature of the area around the user is relatively low and needs to be further quickly heated up. The second preset temperature may be a temperature set by the user according to needs.

[0096] The sub-unit 20 is controlled to supply air toward the user. By controlling the sub-unit 20 to supply air directly toward the user, the user's body surface temperature and the temperature of the area around the user can be quickly adjusted. When the air conditioner is cooling, the user's body surface temperature and the temperature of the area around the user can be quickly reduced to a comfortable range; when the air conditioner is heating, the user's body surface temperature and the temperature of the area around the user can be quickly increased to a comfortable range.

[0097] Optionally, refer to Figure 6 Before controlling the sub-machine 20 to supply air toward the user position, the method may further include: determining that the humidity of the area surrounding the user is not higher than the preset humidity, indicating that the humidity of the area surrounding the user is low at this time. While controlling the sub-machine 20 to supply air toward the user position to quickly adjust the temperature of the area surrounding the user, the humidification module may also be turned on, so that the temperature of the area surrounding the user can be quickly adjusted, and the humidity of the area surrounding the user can also be quickly adjusted, so that the temperature and humidity of the area surrounding the user can be adjusted to a comfortable range, thereby better improving the user's comfort.

[0098] Furthermore, during cooling operation, if the temperature in the area surrounding the user is determined to be higher than a first preset temperature and the humidity in the area surrounding the user is determined to be lower than a preset humidity, indicating that the temperature in the area surrounding the user is relatively high and requires further rapid cooling, and the humidity is relatively low. Controlling the air supply from slave unit 20 can rapidly lower the temperature in the area surrounding the user, while activating the humidification module can rapidly raise the humidity in the area surrounding the user. Humidification increases humidity while water evaporation provides a certain amount of cooling capacity. Therefore, slave unit 20 not only enhances the user's perceived humidity but also lowers the temperature, improving the user's perceived temperature (1L of water evaporating generates approximately 2400kJ of cooling capacity).

[0099] In some optional embodiments of the present invention, referring to Figure 6Before the slave 20 is controlled to operate, for example, before the slave 20 is controlled to supply air toward the user or toward the return air outlet 111 of the main unit 10, the slave 20 can be controlled to move to an area outside the air supply range of the main unit 10. For example, before the slave 20 is controlled to supply air toward the user, the slave 20 is controlled to move to an area outside the air supply range of the main unit 10, that is, after the slave 20 moves to an area outside the air supply range of the main unit 10, the slave 20 is controlled to supply air toward the user. This can avoid the discomfort caused by the slave 20 relaying the hot or cold air from the main unit 10 directly blowing toward the user. Because the slave 20 can enhance the air flow in the area around the user, while the slave 20 supplies air to the user to adjust the user's body surface temperature, the temperature adjustment of the area around the user can be accelerated, so that the temperature of the area around the user is adjusted to a comfortable range more quickly.

[0100] For another example, before the sub-machine 20 supplies air toward the return air outlet 111 of the main machine 10, the sub-machine 20 is controlled to move to an area outside the air supply range of the main machine 10. That is, after the sub-machine 20 moves to an area outside the air supply range of the main machine 10, the sub-machine 20 is controlled to supply air toward the return air outlet 111 of the main machine 10. This can avoid the sub-machine 20 relaying the hot air or cold air of the main machine 10 and directly delivering the hot air or cold air output by the main machine 10 to the return air outlet 111 of the main machine 10, thereby reducing the heating / cooling efficiency of the main machine 10.

[0101] After the slave unit 20 moves to an area outside the air supply range of the main unit 10, the slave unit 20 is controlled to supply air toward the return air outlet 111 of the main unit 10. The slave unit 20 sucks the air from the area outside the air supply range of the main unit 10 and delivers it to the return air outlet 111 of the main unit 10, which is equivalent to increasing the return air volume of the main unit 10, improving the heating / cooling efficiency of the main unit 10, and having a good disturbing effect on the entire indoor air, which can not only strengthen the air flow in the area around the user, but also strengthen the circulation flow of the entire indoor air, speed up the adjustment of the temperature in the area around the user, so that the temperature in the area around the user is adjusted to a comfortable range more quickly, and at the same time speed up the temperature uniformity of the entire indoor environment.

[0102] According to some embodiments of the present invention, referring to Figure 6 , according to the temperature and humidity of the area around the user, controlling the operation of the slave 20 may include:

[0103] When the host 10 is in cooling operation, if the temperature of the area around the user is determined to be no higher than the first preset temperature, it indicates that the temperature of the area around the user has reached a relatively comfortable temperature range; or, when the host 10 is in heating operation, if the temperature of the area around the user is determined to be no lower than the second preset temperature, it indicates that the temperature of the area around the user has reached a relatively comfortable temperature range;

[0104] Determine that the humidity in the area around the user is not higher than the preset humidity, indicating that the humidity in the area around the user is low and humidification adjustment is required;

[0105] By controlling the slave unit 20 to deliver air toward the main unit 10's air outlet and activating the humidification module, when the temperature in the area surrounding the user reaches a comfortable range, the slave unit 20 is controlled to deliver air toward the main unit 10's air outlet. This allows the airflow from the slave unit 20 to counteract the airflow from the main unit 10's air outlet, reducing or weakening the amount and force of air delivered from the main unit 10's air outlet toward the user, thereby alleviating user discomfort. Furthermore, the operation of the slave unit 20 further enhances the flow of indoor air, thereby further promoting uniform indoor temperature. Simultaneously, by activating the humidification module, the humidity in the area surrounding the user can be increased, bringing both the temperature and humidity around the user within a comfortable range and avoiding discomfort caused by direct airflow.

[0106] In some optional embodiments of the present invention, referring to Figure 6 Before controlling the slave 20 to supply air toward the air outlet of the main unit 10, the slave 20 can be controlled to move into the air supply range of the main unit 10. In this way, the slave 20 can better resist the airflow blown out of the air outlet of the main unit 10, better reduce or weaken the amount and strength of air blown toward the user from the air outlet of the main unit 10, better reduce user discomfort, and further improve comfort.

[0107] Optionally, the value of the "preset humidity" described in the present invention may be different at different temperatures, so that a more appropriate preset humidity value can be matched at different temperatures. After adjusting the humidity to the preset humidity at the corresponding temperature, the overall environment can be made more comfortable.

[0108] Optionally, the comfortable range of temperature and humidity described in the present invention can be defined as: 60% humidity at 26° C. as the upper limit of comfortable temperature and humidity, and 40% humidity at 24° C. as the lower limit of comfortable temperature and humidity. Within this temperature and humidity range, the user feels more comfortable.

[0109] In some embodiments of the present invention, the slave 20 may include a soft air supply mode and a strong air supply mode. The soft air supply mode has a shorter air supply distance, lower air supply speed, and lower air supply intensity than the strong air supply mode. When the slave 20 is supplying air toward the user, the slave 20 may adopt the soft air supply mode. While supplying air toward the user to quickly adjust the temperature of the area around the user, it can avoid strong wind blowing directly on the human body and causing discomfort. When the slave 20 is supplying air toward a non-user area, for example, when the slave 20 is supplying air toward the return air vent 111 of the main unit 10 or when the slave 20 is supplying air toward the air supply vent of the main unit 10, the strong air supply mode may be adopted.

[0110] Specifically, when the slave 20 is delivering air toward the return air vent 111 of the main unit 10, the slave 20 uses a strong air supply mode, which can further increase the return air volume of the main unit 10, more quickly and effectively accelerating and strengthening the indoor air circulation, more conducive to maintaining or achieving a comfortable temperature around the user, and more conducive to a more uniform indoor ambient temperature. When the slave 20 is delivering air toward the air supply vent of the main unit 10, the slave 20 uses a strong air supply mode, which can more effectively counteract the airflow from the air supply vent of the main unit 10, and can better disperse the airflow blown out of the air supply vent of the main unit 10, thereby better preventing the airflow from the air supply vent of the main unit 10 from directly hitting the user and causing discomfort.

[0111] The gentle air supply mode and the strong air supply mode of the slave unit 20 may be implemented in the following manners, but not limited to.

[0112] Method 1: The air outlet of the sub-machine 20 is provided with an air guide component for opening and closing the air outlet, and a plurality of tiny air dispersion holes are formed on the air guide component, so that the sub-machine 20 can have a soft air supply mode and a strong air supply mode when working. In the strong air supply mode, the air guide component opens the air outlet to achieve strong air supply; in the soft air supply mode, the air guide component closes the air outlet, and the air flow is dispersed through the plurality of air dispersion holes on the air guide component when passing through the air guide component, making the air output softer.

[0113] Method 2: The sub-fan component 23 of the sub-machine 20 can include only one fan, which can be a centrifugal fan, an axial flow fan or a cross-flow fan. The switching of the air supply mode of the sub-machine 20 can be achieved by adjusting the speed of the fan. For example, the fan speed of the sub-machine 20 in the soft air supply mode is less than the fan speed of the sub-machine 20 in the strong air supply mode.

[0114] Method three: The sub-fan component 23 of the sub-machine 20 can be a counter-rotating fan, which includes two axial-flow fan wheels. The two axial-flow fan wheels can be controlled by a motor respectively, and the motors of the two axial-flow fan wheels can be controlled independently. In this way, by controlling the motors of the two axial-flow fan wheels, the counter-rotating fan can achieve soft air outlet and strong air outlet, thereby switching between soft air supply mode and strong air supply mode.

[0115] Method 4: The sub-unit 20 may include different types of fans. For example, the sub-fan component 23 of the sub-unit 20 may include a first fan 231 and a second fan 232, wherein the first fan 231 may be a centrifugal fan, and the second fan 232 may be an axial flow fan, a counter-rotating fan, or a cross-flow fan. In the strong air supply mode, the first fan 231 operates; in the soft air supply mode, the second fan 232 operates. In addition, when the second fan 232 is located downstream of the first fan 231, in the soft air supply mode, both the first fan 231 and the second fan 232 can operate. After at least a portion of the strong wind generated by the first fan 231 passes through the second fan 232, the airflow can be softened, making the air output softer.

[0116] According to some embodiments of the present invention, controlling the operation of the slave 20 based on the temperature and humidity of the area surrounding the user includes:

[0117] Determining that the humidity in the area around the user is not higher than the preset humidity, indicating that the humidity in the area around the user is low at this time;

[0118] Controlling the air supply of the slave unit 20 and turning on the humidification module to supply air through the slave unit 20 so that when the air flows through the humidification module of the slave unit 20, the humidification module humidifies the air. The humidified air is then delivered to the area around the user and other locations in the room through the air outlet of the slave unit 20, thereby increasing the humidity in the area around the user and improving comfort.

[0119] The speed of the slave unit 20 can be determined based on the temperature and humidity of the area surrounding the user. The faster the speed of the slave unit 20, the more conducive it is to promoting the evaporation of water from the wet film of the humidification module, thereby improving the humidification efficiency of the humidification module. Furthermore, the evaporation efficiency of the wet film of the humidification module is also affected by the temperature of the area surrounding the user. The higher the temperature, the higher the evaporation efficiency of the wet film, and the higher the humidification efficiency of the humidification module. By determining the speed of the slave unit 20 based on the temperature and humidity of the area surrounding the user, the speed of the slave unit 20 can be set within a reasonable range, ensuring humidification efficiency while also saving energy.

[0120] In some optional embodiments of the present invention, the rotation speed of the slave 20 is determined according to the temperature and humidity of the area around the user, which may specifically include:

[0121] Determining the moisture content of the area surrounding the user based on the temperature and humidity of the area surrounding the user;

[0122] Convert the moisture content of the area around the user into relative humidity at a set temperature;

[0123] The rotation speed of the handset 20 is determined according to the relative humidity and the temperature of the area surrounding the user.

[0124] By converting the humidity of the air around the user into relative humidity at the same temperature, for example, regardless of the temperature around the user, it can be converted to relative humidity at a set temperature (e.g., 26°C). This allows humidity values ​​detected at different temperatures to be converted to relative humidity at the same standard, enabling better and more accurate control of the rotation speed of the slave unit 20. As mentioned above, humidity and temperature both affect the evaporation efficiency of the wet film of the humidification module. Determining the rotation speed of the slave unit 20 based on relative humidity and temperature is more rational, ensuring humidification efficiency, further accurately and rapidly increasing indoor humidity, and saving energy.

[0125] Reference Figure 1-Figure 3 Combined with Figure 4-Figure 6 The air conditioner according to the second embodiment of the present invention includes: a main unit 10 and a sub-unit 20.

[0126] The main unit 10 includes a heat exchange and air supply unit and a control device for the main unit 10. A slave unit 20 is detachably mounted on the main unit 10. The slave unit 20 includes an air supply processing unit and a control device for the slave unit 20. When the slave unit 20 is separated from the main unit 10, the slave unit 20 is movable. The control device of the slave unit 20 communicates with the control device of the main unit 10. The control device of the slave unit 20 and the control device of the main unit 10 jointly control the air conditioner to operate according to the control method according to the first embodiment of the present invention.

[0127] According to the air conditioner of the embodiment of the present invention, after the main unit 10 is turned on, the sub-unit 20 can be controlled to move to the area around the user, and the temperature and humidity of the area around the user can be accurately collected. The operation of the sub-unit 20 is controlled according to the temperature and humidity of the area around the user, and the air flow in the area around the user can be enhanced, so that the temperature in the area around the user quickly reaches a more comfortable temperature, and the humidity in the area around the user can be quickly adjusted, so that the temperature and humidity in the area around the user can be adjusted to a comfortable range more quickly, thereby improving comfort and meeting higher needs of users.

[0128] Face Reference Figures 1-6 An air conditioner and a control method of the air conditioner according to some specific embodiments of the present invention are described.

[0129] Reference Figure 1-Figure 3In this embodiment, the air conditioner is a split floor-standing air conditioner, comprising an indoor air conditioner 100 and an outdoor air conditioner, wherein the indoor air conditioner 100 comprises the aforementioned main unit 10 and sub-unit 20. The main unit 10 comprises a main housing 11 and a heat exchange and air supply unit. The main housing 11 defines a receiving chamber and an installation chamber 13, which are spaced apart from each other. The receiving chamber is located above the installation chamber 13, and the heat exchange and air supply unit is installed in the receiving chamber. The sub-unit 20 can also be installed in the installation chamber 13. A return air vent 111 is formed on the rear side wall of the receiving chamber, and an air supply vent is formed on the front side wall of the receiving chamber. A switch door 12 for opening and closing the air supply vent is provided at the air supply vent.

[0130] The slave 20 can be separated from the main unit 10 and placed on the ground. The slave 20 can be automatically moved as required.

[0131] Reference Figure 4 and Figure 5 ( Figure 4 and Figure 5 The direction of the arrow in the figure is the direction of airflow), specifically, the sub-machine 20 includes a sub-housing 21 and an air supply processing unit, the air supply processing unit is arranged in the sub-housing 21, and air inlets are formed on the left and right sides and the lower part of the sub-housing 21, and an air outlet is formed on the front upper side of the sub-housing 21, and the air inlet is located below the air outlet. The air supply processing unit includes a sub-blower component 23 and a humidification module. The humidification module is arranged adjacent to the air inlet. The sub-blower component 23 includes a first fan 231 and a second fan 232 arranged vertically, wherein the second fan 232 is located above the first fan 231. The first fan 231 is a centrifugal fan, and the second fan 232 is an axial fan. The rotation axis of the first fan 231 extends in the left-right direction, and the rotation axis of the second fan 232 extends forward in a back-to-front direction. For example, the angle between the rotation axis of the second fan 232 and the horizontal plane can range from 30-85 degrees, and for example, the angle between the rotation axis of the second fan 232 and the horizontal plane can range from 70 degrees. The air inlet side of the second fan 232 is adjacent to the air outlet side of the first fan 231.

[0132] When only the first fan 231 is operating, external air enters the first fan 231 from the air inlet, is then blown out from the outlet side of the first fan 231, and finally blows out through the outlet. When both the first fan 231 and the second fan 232 are operating, external air enters the first fan 231 from the air inlet, is then blown out from the outlet side of the first fan 231, is softened by the second fan 232, and finally blows out through the outlet. When the slave unit 20 is in the strong air supply mode, only the first fan 231 of the first and second fans 232 is turned on; when the slave unit 20 is in the soft air supply mode, both the first fan 231 and the second fan 232 are turned on. When the first fan 231 is operating, the humidification module can be turned on to achieve humidification.

[0133] The control method of the air conditioner in this embodiment will be described below by taking the cooling operation of the air conditioner as an example.

[0134] Reference Figure 6 , the control method of the air conditioner in this embodiment may include:

[0135] S01, control the cooling operation of the air conditioner;

[0136] S02, collecting user location;

[0137] S03, controlling the slave 20 to move to the area around the user;

[0138] S04, collecting and determining whether the temperature of the area around the user is higher than a first preset temperature;

[0139] S05: Collect and determine whether the humidity in the area around the user is higher than a preset humidity.

[0140] If it is confirmed that the temperature of the area around the user is higher than the first preset temperature and the humidity of the area around the user is higher than the preset humidity, it indicates that the current state is high temperature and high humidity, and then the following steps S11 and S12 are executed:

[0141] S11, controlling the slave 20 to move to an area outside the air supply range of the main unit 10. If the slave 20 is already outside the air supply range of the main unit 10, the slave 20 may remain stationary.

[0142] S12: Controlling the slave unit 20 to supply air toward the return air vent 111 of the main unit 10 effectively increases the return air volume of the main unit 10, thereby improving the cooling efficiency of the main unit 10. Furthermore, the slave unit 20 can significantly disturb the indoor air, for example, creating a negative pressure in the area surrounding the user, thereby promoting air flow around the user. This can quickly adjust the temperature around the user and the temperature of the entire indoor environment, and contribute to a more uniform indoor temperature. Furthermore, the air supply from the slave unit 20 can accelerate and strengthen indoor air flow, and to a certain extent, reduce the discomfort caused by excessive humidity.

[0143] If it is confirmed that the temperature of the area around the user is higher than the first preset temperature and the humidity of the area around the user is not higher than the preset humidity, it indicates that the current state is high temperature and low humidity, and then the following steps S21 and S22 are executed:

[0144] S21, control the slave 20 to move to an area outside the air supply range of the main unit 10. If the slave 20 is already outside the air supply range of the main unit 10, the slave 20 may remain stationary.

[0145] S22: Control the slave unit 20 to deliver air toward the user. Both the first and second fans 231 and 232 are turned on, and the humidification module is turned on. The air processed by the first fan 231 is then softened by the second fan 232 before being delivered to the user. This can reduce the discomfort caused by direct airflow to the user. Furthermore, in low humidity conditions, delivering air directly toward the user not only accelerates the reduction of the user's body temperature and the temperature of the area surrounding the user, but also accelerates the evaporation of moisture from the user's body surface, resulting in a more noticeable cooling sensation for the user compared to high temperature and high humidity conditions. Furthermore, while humidification increases humidity, water evaporation provides a certain amount of cooling. Combined with the softening of the airflow by the second fan 232, the slave unit 20 not only enhances the user's perceived humidity but also reduces the temperature, improving the user's perceived temperature.

[0146] If it is confirmed that the temperature of the area around the user is not higher than the first preset temperature and the humidity of the area around the user is higher than the preset humidity, it indicates that the current state is low temperature and high humidity, and then the following steps S31 and S32 are executed:

[0147] S31, control the slave 20 to move to an area outside the air supply range of the main unit 10. If the slave 20 is already outside the air supply range of the main unit 10, the slave 20 may remain stationary.

[0148] S32, control the sub-machine 20 to supply air toward the return air outlet 111 of the main machine 10, and only turn on the first fan 231 to supply air toward the return air outlet 111 of the main machine 10, which is equivalent to increasing the return air volume of the main machine 10, strengthening the air circulation, and causing a greater disturbance to the indoor air through the sub-machine 20, for example, forming a negative pressure in the area around the user, promoting the air flow in the area around the user, and being beneficial to the uniformity of the indoor temperature. The sub-machine 20 supplies air toward the return air outlet 111 of the main machine 10, which can accelerate and strengthen the indoor air flow, and to a certain extent, can reduce the discomfort caused by excessive humidity; at the same time, the wind speed blowing toward the user can be reduced.

[0149] If it is confirmed that the temperature of the area around the user is not higher than the first preset temperature and the humidity of the area around the user is not higher than the preset humidity, it indicates that the current state is low temperature and low humidity, and then the following steps S41 and S42 are executed:

[0150] S41, control the slave 20 to move to the air supply range of the main unit 10. If the slave 20 is already within the air supply range of the main unit 10, the slave 20 may remain stationary.

[0151] S42: Control the slave unit 20 to supply air toward the air outlet of the main unit 10 and turn on the humidification module. The slave unit 20 can be moved to a position between the air outlet of the main unit 10 and the user, and only the first fan 231 can be turned on to supply air toward the air outlet of the main unit 10, so as to better resist the strong wind sent out from the air outlet of the main unit 10, so as to soften the wind sent out from the air outlet of the main unit 10, thereby softening the wind feeling and increasing the humidity.

[0152] It should be noted that when the air conditioner receives a new instruction, the air conditioner can exit the above operating mode.

[0153] The control method of the air conditioner of this embodiment collects the temperature and humidity around the user through the slave unit 20, and combines the movement of the slave unit 20 and the wind field of the slave unit 20 to achieve microclimate adjustment.
