Description

Technical Field

[0001] The present invention relates to the technical field of air treatment equipment, and in particular to an air conditioner and a control method thereof. Background Art

[0002] In the related art, the heating / cooling of the air conditioner is achieved by sending out the temperature-varied airflow along with the air outlet through the air outlet of the air conditioner. After the airflow leaves the air outlet of the air conditioner, it is only affected by the state of the airflow itself and the environment, resulting in uneven indoor ambient temperature and reducing the comfort of using the air conditioner. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a method for controlling an air conditioner that improves the comfort of air conditioner use. The method also enhances airflow in the area surrounding the user by using a slave unit. Combined with the slave unit's negative air pressure, this method draws the upper airflow downward, achieving temperature migration in the area surrounding the slave unit. This allows the lower temperature in the area surrounding the user to quickly reach a more comfortable level, further enhancing the comfort of air conditioner use.

[0049] 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.

[0050] Reference below Figures 1-6 A method for controlling an air conditioner according to an embodiment of the present invention is described.

[0051] 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, the slave unit 20 may be mounted to the main unit 10. When the slave unit 20 is mounted to the main unit 10, the slave unit 20 may be mounted outside the main unit 10 or inside the main unit 10.

[0052] 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 can be rotated to open and close the separation opening 14.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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 a heating / cooling function. When the sub-unit 20 is in operation, the sub-blower component 23 operates, driving external air into the sub-housing 21 from the air inlet and then blowing it out into the room from the air outlet. Furthermore, the air supply processing unit may also include at least one of a humidification module and a purification module, so that the sub-unit 20 has at least one of a humidification and purification function. This can humidify and / or purify the indoor air, thereby improving the indoor air quality. Furthermore, when the sub-unit 20 is moved near a user, the sub-unit 20 can quickly humidify and / or purify the air near the user.

[0057] 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 ).

[0058] The slave 20 and the main unit 10 can communicate with each other. The slave 20 can transmit collected information (such as temperature and location information) to the main unit 10, and can also transmit information about the slave 20's operating status to the main unit 10. The main unit 10 can also transmit collected information (such as temperature and location information) to the slave 20, and can also transmit information about the main unit 10's operating status 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 location based on the user's location, providing air to the user or humidifying / purifying 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 air conditioner, thereby enhancing the flow of indoor air and thus promoting a uniform indoor 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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 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 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 becomes 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.

[0063] The control method of the air conditioner includes:

[0064] 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;

[0065] After the main unit 10 is turned on, the slave unit 20 is controlled to automatically move. The slave unit 20 can be controlled to move to the area around the user and stop moving after moving to the area around the user. The slave unit 20 can move to the area around the user immediately after the main unit 10 is turned on, or the slave unit 20 can move to the area around the user after the main unit 10 has been running for a period of time in heating or cooling mode. The user's position can be collected by the main unit 10 or the slave unit 20, for example, by using an infrared camera on the main unit 10 or the slave unit 20. The slave unit 20 can automatically move to the area around the user based on the user's position. Of course, when the slave unit 20 is already in the area around the user, the slave unit 20 can remain stationary.

[0066] After the slave 20 moves to the area around the user, the slave 20 may collect the temperature of the area around the user. For example, the temperature of the area around the user may be collected by a temperature sensor on the slave 20, and the collected temperature of the area around the user may be compared with a first preset temperature to determine that the temperature of the area around the user reaches the first preset temperature.

[0067] When it is determined that the temperature of the area surrounding the user has reached a first preset temperature, the slave unit 20 is controlled to blow air toward the non-user area. When it is determined that the temperature of the area surrounding the user has reached the first preset temperature, it indicates that the temperature of the area surrounding the user has reached a relatively comfortable temperature. In this case, the slave unit 20 is controlled to blow air toward the non-user area. This allows the slave unit 20 to blow air toward areas other than the user's location. When the temperature of the area surrounding the user has reached a relatively comfortable temperature, the slave unit 20 can be prevented from blowing air directly toward the user, thereby improving the comfort of air conditioner use.

[0068] In addition, through the operation of the sub-unit 20, the air flow in the area around the user can be strengthened. Combined with the negative pressure of the air inlet of the sub-unit 20, the upper air flow is attracted to move downward, thereby realizing the temperature migration of the area around the sub-unit 20, so that the low temperature in the area around the user can quickly reach a more comfortable temperature, further improving the comfort of using the air conditioner.

[0069] It should be noted that “the temperature of the area around the user reaches the first preset temperature” may mean that the temperature of the area around the user rises from a low temperature to reach the first preset temperature, or may mean that the temperature of the area around the user drops from a high temperature to reach the first preset temperature.

[0070] 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 of the area around the user. When the temperature of the area around the user is lower than the first preset temperature, the sub-unit 20 continues to collect the temperature of the area around the user. When the temperature of the area around the user is not lower than the first preset temperature, the sub-unit 20 is controlled to supply air toward the non-user area to avoid the discomfort caused by hot air blowing directly on people, and to strengthen the airflow in the area around the user, thereby further making the temperature uniform.

[0071] Specifically, the hot air rises under the influence of its own gravity. The sub-unit 20 can transport the lower-temperature airflow upward, creating air disturbance. By moving the lower-temperature airflow upward, the air temperature at the upper level drops, making the airflow at the upper level more fluid. A negative pressure zone forms near the air inlet of the sub-unit 20, forcing the higher-temperature airflow 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 sub-unit 20 moves to the area surrounding the user, the overall temperature of the air in the area surrounding the user is more uniform from top to bottom, improving comfort. Furthermore, the temperature migration around the sub-unit 20 raises the lower temperature of the area surrounding the user, which helps to increase the temperature of the lower limbs, such as the feet, making the user's lower limbs feel warmer.

[0072] For example, when the air conditioner is in cooling operation, after the sub-unit 20 moves to the area around the user, the sub-unit 20 collects the temperature of the area around the user. When the temperature of the area around the user is higher than the first preset temperature, the sub-unit 20 continues to collect the temperature of the area around the user. When the temperature of the area around the user is not higher than the first preset temperature, the sub-unit 20 is controlled to supply air toward the non-user area to avoid the discomfort caused by the cold air blowing directly on people, and to strengthen the airflow in the area around the user, thereby further making the temperature uniform.

[0073] Specifically, as the cold air flows downward under its own gravity, the slave unit 20 can transport the cooler air from the lower locations upward, creating air disturbance. This upward movement of the cooler air at the lower locations reduces the temperature of the air at the higher locations, enhancing airflow at the higher locations. A negative pressure zone forms near the air inlet of the slave unit 20, forcing the warmer air at the higher locations to flow downward, increasing the temperature of the air at the lower locations. This accelerates and strengthens the flow of indoor air, thereby promoting uniform indoor temperature. When the slave unit 20 moves to the area surrounding the user, the overall temperature of the air in the area surrounding the user is more uniform from top to bottom, improving comfort.

[0074] It should be noted that the first preset temperature may have different values ​​when the air conditioner is in heating operation and in cooling operation.

[0075] 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 more comfortable temperature range and maintained within the comfortable temperature range. In particular, the temperature at the lower part of the user surrounding area can be adjusted to a comfortable temperature range.

[0076] Optionally, the "area surrounding the user" can be 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 or near the sub-unit 20. When the sub-unit 20 is operating, the sub-unit 20 can enhance the airflow in the area surrounding the user, thereby facilitating rapid temperature adjustment of the area surrounding the user, allowing the temperature in the area surrounding the user to be quickly adjusted to a more comfortable temperature range and maintained within a comfortable temperature range, particularly allowing the temperature in the lower part of the area surrounding the user to be adjusted to a comfortable temperature range; and, this can avoid discomfort caused by the sub-unit 20 being too close to the user. Furthermore, the value range of a is 1.5 to 2 meters, for example, a can be 1.5 meters, 1.8 meters, 2 meters, and the like.

[0077] 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 temperature adjustment in the area surrounding the user, and avoids discomfort caused by the handset 20 being too close to the user.

[0078] In some embodiments of the present invention, the handset 20 can also rotate, and the rotation of the handset 20 can be used to adjust and change the horizontal airflow direction of the handset 20. For example, the handset 20 can include a base and a handset body mounted on the base. The handset body includes the aforementioned airflow processing unit. The base can be provided with wheels 22 at the bottom to enable movement of the handset 20. The handset body can rotate relative to the base, and 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° horizontally relative to the base. This allows for convenient adjustment of the horizontal airflow direction of the handset 20 within a wide adjustment range. For example, regardless of the user's location or orientation indoors, for example, when the user is not within the air supply range of the main unit 10, when the slave unit 20 moves into the air supply range of the main unit 10 to take over the cooling / heating capacity of the main unit 10, the slave unit 20 can control the drive mechanism to rotate the slave unit body so that the air outlet of the slave unit 20 faces the user based on the user's specific orientation relative to the slave unit 20, thereby conveniently adjusting and changing the horizontal air supply direction of the slave unit 20. For another example, the air supply direction of the slave unit 20 can also be conveniently controlled and adjusted, so that the slave unit 20 can supply air toward non-user areas.

[0079] According to the control method of the air conditioner according to the embodiment of the present invention, after the main unit 10 is turned on, the sub-unit 20 is controlled to move to the area around the user, so that the temperature of the area around the user can be accurately collected. When the temperature of the area around the user is collected to reach the first preset temperature, the sub-unit 20 is made to supply air toward the non-user area. In this way, when the temperature of the area around the user reaches a more comfortable temperature, the sub-unit 20 can be prevented from blowing air directly toward the user, thereby improving the comfort of using the air conditioner. At the same time, the sub-unit 20 can strengthen the airflow in the area around the user, and combined with the negative pressure of the air inlet of the sub-unit 20, the upper airflow is attracted to move downward, thereby realizing the temperature migration of the area around the sub-unit 20, so that the low temperature in the area around the user quickly reaches a more comfortable temperature, further improving the comfort of using the air conditioner.

[0080] According to some embodiments of the present invention, referring to Figure 6 After the main unit 10 is turned on, before the sub-unit 20 is controlled to move to the area around the user, the user's location can be collected and determined, and the sub-unit 20 can be specifically controlled based on whether the user's location is within the air supply range of the main unit 10. Specifically, before the sub-unit 20 is controlled to move to the area around the user, the following steps can be included:

[0081] Collecting the user's location, for example, can be done by using an infrared camera on the slave 20 or an infrared camera on the host 10;

[0082] According to the collected user position and the current air supply range of the host 10, it is determined whether the user position is within the air supply range of the host 10;

[0083] If the user is within the air supply range of the main unit 10, air is directly supplied to the user through the air supply port of the main unit 10, and the temperature of the area around the user can be quickly adjusted (the adjustment means increasing when heating or decreasing when cooling), and the slave unit 20 can be controlled to move to the area around the user;

[0084] If the user's position is not within the air supply range of the main unit 10, the sub-unit 20 can be controlled to move within the air supply range of the main unit 10. After the sub-unit 20 moves into the air supply range of the main unit 10, the sub-unit 20 is controlled to supply air toward the user's position. Since the user is not within the air supply range of the main unit 10, the temperature of the area around the user cannot be quickly adjusted. By moving the sub-unit 20 into the air supply range of the main unit 10 and supplying air toward the user, the sub-unit 20 can relay the heat or cold of the main unit 10 to deliver the heat or cold of the machine 10 to the user, thereby quickly adjusting the temperature of the area around the user.

[0085] Before controlling the slave unit 20 to move to the main unit 10, the user's position is collected and determined to be within the air supply range of the main unit 10. Based on this, the slave unit 20 is specifically controlled. This allows the user to quickly adjust the temperature of the area around the user even when the user is not within the air supply range of the main unit 10 through relay air supply from the slave unit 20. This allows the user's surrounding area to be quickly adjusted to a comfortable temperature range regardless of whether the user is within the air supply range of the main unit 10, thereby improving the comfort of the air conditioner.

[0086] According to some optional embodiments of the present invention, referring to Figure 6In the above embodiment of determining whether the user's location is within the air supply range of the main unit 10, if the user's location is determined not to be within the air supply range of the main unit 10, the slave unit 20 moves to the area surrounding the user and supplies air toward the user, thereby quickly adjusting the temperature of the area surrounding the user. While the slave unit 20 supplies air to the user, the return air temperature of the main unit 10 can be detected in real time. For example, the return air temperature of the main unit 10 can be detected by a temperature sensor located at the return air vent 111 of the main unit 10. The return air temperature of the main unit 10 can generally represent the current indoor ambient temperature. When the return air temperature of the main unit 10 reaches the second preset temperature, it indicates that the indoor ambient temperature has generally reached a comfortable range. If the air conditioner is operating in heating mode, the indoor temperature has reached a relatively warm level; if the air conditioner is operating in cooling mode, the indoor temperature has reached a relatively cool level. At this point, the slave unit 20 is no longer required to relay the cooling or heating energy from the main unit 10 to the user. Instead, the slave unit 20 can be controlled to move to the area surrounding the user. After the slave unit 20 moves to the area surrounding the user, the aforementioned data acquisition can be performed to determine whether the temperature of the area surrounding the user has reached the first preset temperature.

[0087] In an embodiment where the user's position is not within the air supply range of the main unit 10, when the return air temperature of the main unit 10 is collected and determined to have reached the second preset temperature, the sub-unit 20 is controlled to move to the area around the user. This ensures that before the sub-unit 20 moves to the area around the user, the temperature of the area around the user is quickly adjusted through the relay air supply of the sub-unit 20, and avoids the discomfort and energy waste caused by the sub-unit 20 still supplying air toward the user when the indoor temperature has basically reached a relatively comfortable temperature range.

[0088] According to some optional embodiments of the present invention, referring to Figure 6 The control of moving the slave unit 20 to the air supply range of the host unit 10 may include:

[0089] During the movement of the sub-machine 20, the air inlet position of the sub-machine 20 can be detected in real time. According to whether the air inlet position of the sub-machine 20 is within the air supply range of the main machine 10, it is judged whether the sub-machine 20 has moved into the air supply range of the main machine 10. When it is determined that the air inlet position of the sub-machine 20 is within 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 and stays within the air supply range of the main machine 10.

[0090] By determining that the air inlet position of the sub-machine 20 is within the air supply range of the main machine 10, the basis for determining that the sub-machine 20 is moved to the air supply range of the main machine 10 is determined. In this way, when the sub-machine 20 is within the air supply range of the main machine 10, the air inlet area of ​​the sub-machine 20 can be located within the air supply range of the main machine 10. In this way, the sub-machine 20 can accelerate the hot air or cold air sent by the main machine 10 after entering the sub-machine 20 through the air inlet and then transport it toward the user through the air outlet of the sub-machine 20. This can enable the sub-machine 20 to better relay the heat or cold of the main machine 10, thereby transporting more heat or cold to the area around the user, so that the temperature of the area around the user can be quickly adjusted.

[0091] According to some embodiments of the present invention, referring to Figure 6 The control of the sub-machine 20 to supply air toward the non-user area may include:

[0092] The air supply direction of the slave unit 20 is controlled based on the position of the user relative to the air supply area of ​​the main unit 10. This allows the slave unit 20 to supply air in a direction that is conducive to improving user comfort based on the user's specific location. This not only quickly adjusts the temperature in the area around the user, enhances indoor air flow, helps achieve uniform indoor ambient temperature, but also further improves comfort.

[0093] For example, in some optional embodiments of the present invention, controlling the air supply direction of the slave 20 based on the positional relationship of the user position relative to the air supply area of ​​the main unit 10 may include:

[0094] When it is determined that the user is not within the air supply range of the main unit 10, the slave unit 20 can be controlled to supply air upward (either diagonally upward or directly upward). In this case, the user is outside the air supply range of the main unit 10. If the temperature in the area around the user has reached a comfortable temperature, not only can the slave unit 20 and the main unit 10 be prevented from blowing air toward the user, causing discomfort, but also the slave unit 20 can be prevented from blowing air toward the user. In addition, the upward direction of the slave unit 20 can further promote the mutual flow of air between low and high places, further helping to enhance the flow of air in the room, thereby making the room temperature more uniform.

[0095] When it is determined that the user's position is within the air supply range of the main unit 10, the sub-unit 20 can be controlled to supply air toward the air supply outlet of the main unit 10. At this time, the user is within the air supply range of the main unit 10. When the temperature of the area around the user has reached a comfortable temperature, not only can the user's discomfort caused by the sub-unit 20 supplying air toward the user be avoided, but also, by the sub-unit 20 supplying air toward the air supply outlet of the main unit 10, the airflow blown out by the sub-unit 20 can counteract the airflow blown out from the air supply outlet of the main unit 10, reducing or weakening the air volume and strength of the air supplied from the air supply outlet of the main unit 10 toward the user, reducing user discomfort, and through the operation of the sub-unit 20, it is further beneficial to enhance the flow of indoor airflow, thereby being more conducive to the uniformity of indoor temperature.

[0096] Optionally, in an embodiment of controlling the sub-machine 20 to supply air toward the air outlet of the main machine 10 when it is determined that the user position is within the air supply range of the main machine 10, before controlling the sub-machine 20 to supply air toward the air outlet of the main machine 10, the sub-machine 20 can be controlled to move between the user position and the air outlet of the main machine 10. This can enable the sub-machine 20 to better resist the air supply of the main machine 10, and can better reduce or weaken the amount or force of air blown toward the user from the air outlet of the main machine 10, thereby further reducing discomfort.

[0097] In some embodiments of the present invention, the sub-unit 20 may include a gentle air supply mode and a powerful air supply mode. The gentle air supply mode has a shorter air supply distance, lower air speed, or lower air supply intensity than the powerful air supply mode. When the sub-unit 20 is supplying air toward the user, the sub-unit 20 may adopt the gentle air supply mode. While supplying air toward the user to quickly adjust the temperature in the area surrounding the user, it can also avoid strong wind blowing directly on the human body and causing discomfort. When the sub-unit 20 is supplying air toward non-user areas, it can adopt the powerful air supply mode. This can more quickly and effectively accelerate 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. Moreover, when the user is in the air supply area of ​​the main unit 10, the sub-unit 20 supplies air toward the air supply port of the main unit 10. At this time, the sub-unit 20 is in the strong air supply mode, which can more effectively counteract the airflow from the air supply port of the main unit 10, and can better disperse the airflow blown out of the air supply port of the main unit 10, thereby better avoiding the discomfort caused by the airflow blown out of the air supply port of the main unit 10 directly blowing on the user.

[0098] 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.

[0099] Method 1: The air outlet of the sub-machine 20 is provided with an air guide component for opening and closing the air outlet. The air guide component is formed with multiple tiny air dispersion holes. This allows the sub-machine 20 to have a soft air supply mode and a strong air supply mode when in operation. 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. When the air flows through the air guide component, it is dispersed by the multiple air dispersion holes on the air guide component, making the air output softer.

[0100] Method 2: The sub-fan component 23 of the slave unit 20 may include only one fan, which may be a centrifugal fan, an axial flow fan, or a cross-flow fan. The fan speed can be adjusted to switch the air supply mode of the slave unit 20. For example, the fan speed of the slave unit 20 in the soft air supply mode is lower than the fan speed of the slave unit 20 in the strong air supply mode.

[0101] Method 3: The sub-fan component 23 of the sub-unit 20 can be a counter-rotating fan, which includes two axial-flow fan wheels. The two axial-flow fan wheels can be independently controlled by two motors. In this way, by controlling the motors of the two axial-flow fan wheels, the counter-rotating fan can achieve soft air discharge and strong air discharge, thereby switching between soft air supply mode and strong air supply mode;

[0102] Method 4: The sub-machine 20 may include different types of fans. For example, the sub-fan component 23 of the sub-machine 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, only the first fan 231 operates; in the soft air supply mode, only the second fan 232 operates. Alternatively, 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 may 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 dispersed, making the air output softer. In the strong air supply mode, only the first fan 231 operates.

[0103] According to some embodiments of the present invention, referring to Figure 6 Before collecting and determining that the temperature of the area around the user reaches the first preset temperature, the method may further include:

[0104] The return air temperature of the host 10 is collected, and it is determined that the return air temperature of the host 10 reaches the second preset temperature. When the return air temperature of the host 10 is collected and determined to have reached the second preset temperature, it means that the indoor ambient temperature has generally reached a relatively comfortable range. If the air conditioner is running in heating mode, it means that the indoor temperature has reached a relatively warm level; if the air conditioner is running in cooling mode, it means that the indoor temperature has reached a relatively cool level. At this time, the above-mentioned collection can be implemented to determine whether the temperature of the area around the user has reached the first preset temperature.

[0105] Generally speaking, the temperature measured at the return air outlet 111 of the host 10 reaches the expected temperature earlier than the temperature of the area around the user. By first collecting and determining that the return air temperature of the host 10 reaches the second preset temperature, and then collecting and determining whether the temperature of the area around the user reaches the first preset temperature, the temperature of the area around the user can be collected after the indoor ambient temperature roughly reaches a relatively comfortable range. This can improve the accuracy of collecting the temperature of the surrounding users and avoid errors caused by randomness in the collection.

[0106] Optionally, the second preset temperature may be a temperature set by the user, for example, a set temperature set by the user via a remote controller.

[0107] Optionally, the second preset temperature may be the same as the first preset temperature, or may be different from the first preset temperature. For example, when the air conditioner is in heating mode, the second preset temperature may not be lower than the first preset temperature, thereby ensuring that the temperature around the user is within a comfortable range when the air conditioner is in heating mode; and when the air conditioner is in cooling mode, the second preset temperature may not be higher than the first preset temperature, thereby ensuring that the temperature around the user is within a cool and comfortable range when the air conditioner is in cooling mode.

[0108] According to some embodiments of the present invention, referring to Figure 6 , controlling the slave unit 20 to supply air toward the non-user area, including:

[0109] The humidification function of the sub-unit 20 can be turned on. Specifically, the humidification module of the air supply processing unit can be turned on to humidify the indoor air, especially the air in the area around the user, so that the temperature and humidity in the area around the user are within a comfortable range, further improving the comfort level.

[0110] Optionally, before activating the humidification module, the humidity of the area surrounding the user can be collected. For example, the humidity of the area surrounding the user can be collected using a humidity sensor on the slave unit 20. When it is determined that the humidity of the area surrounding the user is lower than a first preset humidity, the humidification module can be controlled to activate, thereby humidifying the indoor air and increasing the indoor humidity, so that the temperature and humidity of the area surrounding the user are both within a comfortable range, further improving the comfort level. When the collected indoor humidity or the humidity of the area surrounding the user is higher than a second preset humidity, the humidification module can be controlled to stop operating, thereby stopping humidification, so that the temperature and humidity of the area surrounding the user are both within a comfortable range. The second preset humidity is greater than the first preset humidity.

[0111] Optionally, the humidification module may include a wet cotton component and a water pump for spraying water on the wet cotton component. By controlling the start and stop of the water pump, the start and stop of the humidification module can be conveniently controlled.

[0112] 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.

[0113] 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.

[0114] According to the air conditioner of the embodiment of the present invention, after the main unit 10 is turned on, the sub-unit 20 is controlled to move to the area around the user, so that the temperature of the area around the user can be accurately collected. When the temperature of the area around the user is collected to reach the first preset temperature, the sub-unit 20 is made to supply air toward the non-user area. In this way, when the temperature of the area around the user reaches a more comfortable temperature, the sub-unit 20 can be avoided from blowing air directly toward the user, thereby improving the comfort of using the air conditioner. At the same time, the sub-unit 20 can strengthen the airflow in the area around the user, and combined with the negative pressure of the air inlet of the sub-unit 20, it attracts the upper airflow to move downward, realizing the temperature migration of the area around the sub-unit 20, so that the low temperature in the area around the user quickly reaches a more comfortable temperature, further improving the comfort of using the air conditioner.

[0115] Refer to the following 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.

[0116] Reference Figure 1-Figure 3In this embodiment, the air conditioner is a split floor-standing air conditioner, comprising an indoor air conditioner unit 100 and an outdoor air conditioner unit, wherein the indoor air conditioner unit 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 storage chamber and an installation chamber 13 spaced apart from each other. The storage chamber is located above the installation chamber 13. The heat exchange and air supply unit is installed in the storage chamber, and the sub-unit 20 can be installed in the installation chamber 13. A return air vent 111 is formed on the rear side wall of the storage chamber, and an air supply vent is formed on the front side wall of the storage chamber. The air supply vent is provided with a switch door 12 for opening and closing the air supply vent. The sub-unit 20 can be separated from the main unit 10 and placed on the ground. The sub-unit 20 can be automatically moved as required.

[0117] 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 upward in the back-to-front direction. For example, the angle between the rotation axis of the second fan 232 and the horizontal plane can range from 30-75 degrees, 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.

[0118] 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.

[0119] The control method of the air conditioner in this embodiment will be described below using the heating operation of the air conditioner.

[0120] Reference Figure 6 , the control method of the air conditioner in this embodiment may include:

[0121] S01, control the heating operation of the air conditioner;

[0122] S02. Collect and determine whether the user position is within the air supply range of the host 10. If it is confirmed that the user position is within the air supply range of the host 10, execute the following steps S11-S17; if it is confirmed that the user position is not within the air supply range of the host 10, execute the following steps S21-S28.

[0123] Specifically, after confirming that the user position is within the air supply range of the host 10, the following steps S11-S17 are performed:

[0124] S11, controlling the slave 20 to move to the area around the user or to remain stationary. If the slave 20 is already in the area around the user, it can remain stationary.

[0125] S12, collecting the return air outlet temperature of the host 10;

[0126] S13, determining that the return air outlet temperature of the host 10 is not lower than a second preset temperature;

[0127] S14, collecting the temperature of the area around the user;

[0128] S15. Determine whether the temperature of the area around the user is not lower than a first preset temperature;

[0129] S16, controlling the slave 20 to move between the user's location and the host 10;

[0130] S17 , the slave unit 20 is controlled to turn on and supply air toward the air outlet of the main unit 10 , and the humidification module of the slave unit 20 is turned on. At this time, the slave unit 20 is in a strong air supply mode.

[0131] Specifically, after confirming that the user position is not within the air supply range of the host 10, the following steps S21-S28 are performed:

[0132] S21, control the slave unit 20 to move to the air supply range of the main unit 10;

[0133] S22, controlling the slave unit 20 to turn on and supply air toward the user's position. At this time, the slave unit 20 is in a soft air supply mode;

[0134] S23, collecting the return air outlet temperature of the host 10;

[0135] S24, determining that the return air outlet temperature of the host 10 is not lower than a second preset temperature;

[0136] S25, controlling the slave 20 to move to the area around the user;

[0137] S26. Collect the temperature of the area around the user;

[0138] S27, determining that the temperature of the area around the user is not lower than a first preset temperature;

[0139] S28 , controlling the slave unit 20 to turn on and blow air toward the non-user area, and turning on the humidification module of the slave unit 20 . At this time, the slave unit 20 is in a strong air supply mode.

[0140] When the air conditioner is in heating operation using the above control method, the movement of the sub-unit 20 is controlled according to whether the user's position is within the air supply range of the main unit 10, so that the temperature of the area around the user can be quickly adjusted regardless of whether the user's position is within the air supply range of the main unit 10.

[0141] If the return air temperature of the main unit 10 reaches the second preset temperature, indicating that the indoor temperature has reached a relatively warm level, the aforementioned data collection can be performed to determine whether the temperature in the area surrounding the user has reached the first preset temperature. If the temperature in the area surrounding the user is not lower than the first preset temperature, the slave unit 20 can be controlled to direct air toward the non-user area to prevent discomfort caused by direct hot air. This can also enhance airflow in the area surrounding the user, further evening out the temperature.

[0142] Specifically, the hot air rises under the influence of its own gravity. The sub-unit 20 can transport the lower-temperature airflow upward, creating air disturbance. By moving the lower-temperature airflow upward, the air temperature at the upper level drops, making the airflow at the upper level more fluid. A negative pressure zone forms near the air inlet of the sub-unit 20, forcing the higher-temperature airflow 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 sub-unit 20 moves to the area surrounding the user, the air temperature in the area surrounding the user becomes more uniform from top to bottom, improving comfort. Furthermore, the temperature migration around the sub-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.
