Description

Technical Field

[0001] This invention belongs to the field of air handling equipment technology, specifically an air conditioner and its fresh air outlet control method. Background Technology

[0002] To improve indoor air quality, air handling equipment is typically used to purify the air or adjust its physical and chemical properties.

[0003] In related technologies, air conditioners are often equipped with fresh air components to provide fresh air to the room; the heat exchange components in the air conditioner can regulate the indoor air temperature. In the process of air outlet, existing fresh air components either release the air together with the heat-exchanged air to regulate the comfort of the fresh air outlet, or they are equipped with a temperature processing device to separately regulate the outlet air temperature of the fresh air module to improve the comfort of the fresh air outlet.

[0004] However, existing air conditioners typically rely on ambient temperature sensors located at specific locations to regulate indoor heat exchange air, and then adjust the fresh air outlet temperature based on the indoor heat exchange air. This method is slow in adjusting the fresh air outlet temperature and offers limited control over the fresh air supply, failing to provide differentiated fresh air delivery for specific users or meet their diverse fresh air needs in various scenarios. Since users are constantly moving indoors, their distance from the air conditioner changes, meaning they may not receive sufficient comfortable fresh air after changing positions, thus hindering the user experience. While some portable air conditioners incorporate air purification components to regulate indoor air quality, they generally do not deliver fresh air to the user. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes an air conditioner that can adjust the air outlet status of each fresh air outlet in real time based on the environmental parameters around the user collected by the mobile unit and the fresh air outlet parameters of the fresh air module. This results in good fresh air outlet differentiation and high fresh air outlet comfort, solving the technical problems of slow fresh air outlet adjustment, single fresh air outlet control, and inability to form differentiated services in the prior art.

[0006] The present invention also aims to provide a method for controlling the fresh air outlet of an air conditioner as described above.

[0007] An air conditioner according to an embodiment of the present invention includes: a main unit, the main unit comprising: a main unit housing, the main unit housing having a fresh air inlet and at least two fresh air outlets with different opening directions; a fresh air module disposed in the main unit housing and respectively connected to the fresh air inlet and the fresh air outlets; a first sensor disposed in the main unit housing to detect the fresh air outlet parameters of the fresh air module; a mobile sub-unit and a second sensor, the mobile sub-unit being detachable from the main unit and having the second sensor disposed on it to detect environmental parameters around the user; a control unit in the main unit determining the fresh air outlet comfort level of the main unit based on the environmental parameters and the fresh air outlet parameters, and adjusting the air outlet state of the fresh air outlets accordingly.

[0008] According to an embodiment of the air conditioner of the present invention, the mobile sub-unit can have a different setting position relative to the main unit, so that the mobile sub-unit can be set at a position closer to the user and detect the environmental parameters around the user, thereby accurately obtaining parameter information of the local environment near the user; then, combined with the fresh air outlet parameters of the operating fresh air module, the fresh air outlet comfort level is obtained, and the air outlet state of the fresh air outlet is adjusted so that the fresh air outlet comfort level is within a suitable range, ensuring that the fresh air blown to the user is comfortable and ensuring that uncomfortable fresh air is not blown to the user, so that the main unit and the mobile sub-unit work together to achieve targeted fresh air delivery to users in the room, effectively increasing the fresh air concentration around the user, improving the user experience, and allowing the user to perceive comfortable and fresh fresh air.

[0009] Optionally, the fresh air outlet parameters include fresh air temperature and / or fresh air humidity.

[0010] Optionally, the environmental parameters include ambient temperature and / or ambient humidity.

[0012] According to some embodiments of the air conditioner of the present invention, the fresh air module includes a fresh air housing, a fresh air fan, and a temperature regulation module.

The fresh air fan is disposed in the fresh air housing to guide fresh air from the fresh air inlet to the fresh air outlet, and the fresh air fan is adjustable to a preset wind speed. The temperature regulation module is disposed in the fresh air housing to adjust the fresh air temperature of the fresh air module.

[0013] According to a further embodiment of the present invention, the fresh air module further includes a humidity regulation module, which is used to regulate the fresh air humidity of the fresh air module.

[0014] Optionally, the main unit housing has fresh air outlets on at least the front, left, and right sides.

[0015] Optionally, the main unit housing is provided with a docking compartment, in which the mobile sub-unit can be accommodated; the fresh air module is located on the upper part of the docking compartment.

[0016] According to some embodiments of the present invention, the air conditioner further includes a third sensor, which is disposed on the mobile sub-unit to detect the distance parameter between the user and the main unit and / or detect the user's position parameter. The main unit determines the fresh air comfort level of the main unit based on the environmental parameter, the distance parameter and the fresh air outlet parameter.

[0017] Optionally, when the mobile sub-unit detects multiple users, the control unit can determine the target user based on the distance parameters between each user and the host.

[0018] Optionally, the main unit further includes an air guide assembly, which is located at the fresh air outlet. The air guide assembly swings to adjust the air outlet direction and / or opening / closing state of the fresh air outlet.

[0019] According to an embodiment of the present invention, a method for controlling the fresh air outlet of an air conditioner in the foregoing examples includes the following steps: controlling the fresh air module to output fresh air at a first preset wind speed, and a first sensor detecting the fresh air outlet parameters of the fresh air module; controlling the mobile sub-unit to move near the user, and a second sensor detecting environmental parameters around the user; determining whether the fresh air outlet comfort level is within a first preset comfort threshold; if so, controlling each of the fresh air outlets to open and output fresh air; if not, controlling the fresh air outlets facing the user to close, while keeping the other fresh air outlets open.

[0020] According to the embodiment of the present invention, the fresh air outlet control method of the air conditioner uses a main unit and a mobile sub-unit in combination, and determines whether the fresh air outlet comfort is within the threshold based on the environmental parameters around the user and the fresh air outlet parameters. Based on the determination result, the air outlet status of each fresh air outlet is further adjusted to deliver comfortable and fresh air to users in specific locations. The fresh air delivery is highly targeted and the comfort is guaranteed.

[0021] According to some embodiments of the present invention, the method for controlling the fresh air outlet of an air conditioner includes the following steps after controlling the fresh air outlet facing the user to close: adjusting the operation of the fresh air module to change the fresh air outlet parameters; re-determining whether the fresh air outlet comfort level is within a first preset comfort threshold based on the changed fresh air outlet parameters and the environmental parameters; if yes, controlling each of the fresh air outlets to open and release fresh air to the outside; if no, controlling the fresh air module to increase the wind speed and release fresh air.

[0022] Optionally, after controlling each fresh air outlet to open and release fresh air, the method further includes the following steps: controlling the fresh air module to release fresh air at a second preset wind speed; determining whether the fresh air outlet comfort level is within a second preset comfort threshold; if yes, controlling each fresh air outlet to release fresh air towards the user; if no, controlling the fresh air outlets facing the user to close.

[0023] Optionally, after controlling each of the fresh air outlets to open and release fresh air, the method further includes the following steps: controlling the fresh air module to increase the airflow to a third preset speed to release fresh air, determining whether the fresh air outlet comfort level is within a third preset comfort threshold; if yes, controlling each of the fresh air outlets to release fresh air towards the user; if no, controlling the fresh air outlets facing the user to close.

[0024] According to some embodiments of the present invention, the air conditioner is an air conditioner including a third sensor. When the mobile sub-unit detects multiple users, it adjusts the air outlet state of the fresh air outlet according to the environmental parameters around the target user closest to the host and the fresh air outlet parameters determined by the control unit.

[0025] Optionally, when the control unit determines that multiple target users exist simultaneously and determines that all fresh air outlets facing the target users need to be closed, it controls each fresh air outlet to rotate at a fourth preset wind speed and controls the fresh air outlets to discharge air towards the side away from the target users, wherein the fourth preset wind speed is less than the first preset wind speed.

[0026] According to some embodiments of the present invention, when the environmental parameter is ambient temperature, the fresh air outlet facing the user is controlled to close when the ambient temperature is less than a first temperature threshold.

[0027] Optionally, when the ambient temperature is within a first temperature threshold and the difference between the fresh air temperature and the ambient temperature is within a first preset difference, the fresh air outlets facing the user are controlled to open and / or each of the fresh air outlets is controlled to deliver fresh air to the user.

[0028] Optionally, when the ambient temperature is within a second temperature threshold and the difference between the fresh air temperature and the ambient temperature is within a second preset difference, the fresh air outlets facing the user are controlled to open and / or each of the fresh air outlets is controlled to deliver fresh air to the user.

[0029] According to some embodiments of the present invention, in the method for controlling the fresh air supply of an air conditioner, when the air conditioner receives a signal to shut off the fresh air supply, the fresh air module stops operating.

[0056] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0057] In the description of this invention, it should be understood that the terms "longitudinal", "length", "width", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0058] The air conditioner 1000 of the present invention is described below with reference to the accompanying drawings. The air conditioner 1000 of the present invention can be used to adjust the physical and chemical properties of air, such as adjusting the temperature, humidity, cleanliness, and odor of the air. The air conditioner 1000 of the present invention can also deliver fresh air to the room and improve the freshness of the indoor air.

[0059] An air conditioner 1000 according to an embodiment of the present invention, such as Figure 1 As shown, it includes a host 100, a mobile sub-unit 200, and a second sensor 320.

[0060] Host 100 includes: Figure 1 and Figure 5 The main unit casing 110 shown in the figure Figure 6 and Figure 7 The fresh air module 120 shown in the image and Figure 7 The first sensor 130 is shown in the figure.

[0061] The main unit housing 110 is provided with a fresh air inlet 112 for introducing fresh air from outside into the main unit housing 110. The main unit housing 110 is also provided with at least two fresh air outlets 113. The opening directions of the various fresh air outlets 113 may be the same or different, but at least two of the fresh air outlets 113 are located on different sides of the main unit housing 110, so that the main unit housing 110 can draw fresh air out in different directions.

[0062] like Figure 6 As shown, the fresh air module 120 is installed in the main unit housing 110 and is connected to the fresh air inlet 112 and the fresh air outlet 113 respectively. The fresh air module 120 can pass fresh air from the fresh air inlet 112 to the fresh air outlet 113, and can also process the introduced fresh air before blowing it into the room from the fresh air outlet 113.

[0063] like Figure 7 As shown, the first sensor 130 is installed in the main unit housing 110 to detect the fresh air output parameters of the fresh air module 120. By detecting the fresh air output parameters, the first sensor 130 can specifically detect the characteristics of the fresh air output, thereby obtaining the characteristics of the fresh air to be introduced into the room.

[0064] Furthermore, such as Figure 1 As shown, the mobile sub-unit 200 can operate independently of the main unit 100. The mobile sub-unit 200 is equipped with a second sensor 320 to detect environmental parameters around the user. The mobile sub-unit 200 can change its position relative to the main unit 100, for example, by manual handling or by its own intelligent mobility components. The second sensor 320 will also follow the mobile sub-unit 200's position relative to the main unit 100, constantly changing location and moving closer to the user.

[0065] The control unit in the main unit 100 determines the comfort level of the fresh air supply based on environmental parameters and fresh air outlet parameters, and adjusts the airflow status of the fresh air outlet 113 accordingly. This control unit can wirelessly communicate with the second sensor 320 to reliably receive the environmental parameters detected by the second sensor 320. The wireless communication method is well-known to those skilled in the art and will not be elaborated upon here. The control unit can also be electrically connected to the first sensor 130 to receive the fresh air outlet parameters detected by the first sensor 130.

[0066] As can be seen from the above structure, in the air conditioner 1000 of the present invention, the mobile sub-unit 200 can have different setting positions relative to the main unit 100, so that the mobile sub-unit 200 can be set at a position closer to the user and detect the environmental parameters around the user, thereby accurately obtaining parameter information in the local environment near the user, such as accurately detecting environmental parameters such as temperature and humidity around the user.

[0067] As the fresh air module 120 continuously discharges fresh air from the fresh air outlet 113 during operation, and the first sensor 130 can detect the fresh air outlet parameters such as temperature and humidity, the control unit can calculate the environmental parameters and the fresh air outlet parameters to obtain the fresh air outlet comfort level.

[0068] The control unit of the present invention can preset a corresponding fresh air outlet comfort threshold. By comparing whether the actual fresh air outlet comfort is within the fresh air outlet comfort threshold, the air outlet state of the fresh air outlet 113 can be adjusted. For example, some fresh air outlets 113 can be closed or opened, or the air guiding direction of some fresh air outlets 113 can be changed, so that the fresh air outlet comfort blowing to the user is within a suitable range, ensuring that the fresh air blowing to the user is comfortable, and ensuring that uncomfortable fresh air is not blown to the user.

[0069] Therefore, the air conditioner 1000 of the present invention uses the main unit 100 and the mobile sub-unit 200 together to achieve targeted fresh air delivery to indoor users, effectively increase the fresh air concentration around users, improve user experience, and enable users to quickly perceive comfortable and fresh fresh air, so that users' needs for fresh air can be quickly met.

[0070] Understandably, compared to the temperature and humidity detectors that are fixed indoors in the prior art, which can only monitor the temperature and humidity at specific locations and cannot quickly and accurately detect and provide feedback on the environmental parameters of users at any location, the air conditioner 1000 of the present invention changes the position of the second sensor 320 carried by the mobile sub-unit 200, so that the second sensor 320 can quickly and accurately measure the environmental parameters around the user at the current location and provide timely feedback to the control unit, so that the control unit can promptly determine the comfort of the fresh air supply.

[0071] Compared to existing air conditioners that cannot accurately deliver comfortable fresh air to users when they change positions indoors, the air conditioner 1000 of this invention, by setting a fresh air module 120 in the main unit 100 and combining the environmental parameters near the user fed back by the mobile sub-unit 200 with the fresh air output parameters of the fresh air module 120, enables the control unit to quickly determine whether the comfort of the fresh air output is reasonable. When reasonable, it controls the fresh air outlet 113 to blow fresh air directly towards the user; when unreasonable, it controls some of the fresh air outlets 113 to close or changes the air output direction of the fresh air outlets 113, thereby effectively preventing discomfort caused by uncomfortable fresh air blowing directly on the user.

[0072] In some embodiments of the present invention, the fresh air outlet parameters include fresh air temperature and / or fresh air humidity. When the fresh air outlet parameters include fresh air temperature, the first sensor 130 is a temperature sensor; when the fresh air outlet parameters include fresh air humidity, the first sensor 130 is a humidity sensor; when the fresh air outlet parameters include both fresh air humidity and fresh air temperature, the first sensor 130 is a temperature and humidity sensor.

[0073] Advantageously, to accurately determine the fresh air outlet parameters, the first sensor 130 is positioned between the fresh air module 120 and the fresh air outlet 113, thereby enabling accurate determination of the properties of the fresh air drawn from the fresh air module 120. For example, in a specific example, the first sensor 130 can be positioned close to the fresh air outlet 113 within the main unit housing 110 to detect the fresh air outlet parameters of the fresh air about to be blown into the room from the fresh air outlet 113; or, in another specific example, the first sensor 130 is positioned in the fresh air duct between the fresh air module 120 and the fresh air outlet 113 to accurately measure the fresh air parameters; or, for yet another example... Figure 7 As shown, the first sensor 130 is installed in the fresh air housing 121 of the fresh air module 120, thereby integrating the first sensor 130 and the fresh air module 120 into one place for easy installation.

[0074] Understandably, people are generally more sensitive to temperature changes, while the humidity change brought about by the introduction of fresh air is not as significant as the temperature change. Therefore, in this specific example, the fresh air outlet parameters primarily focus on detecting the fresh air temperature, supplemented by detecting the fresh air humidity. Correspondingly, the first sensor 130 can primarily be a temperature sensor that is sensitive to temperature, supplemented by a humidity sensor.

[0075] In some embodiments of the present invention, the environmental parameters include ambient temperature and / or ambient humidity. When the fresh air outlet parameter is fresh air temperature, the environmental parameter should be ambient temperature, and the second sensor 320 should be a temperature sensor; when the fresh air outlet parameter is fresh air humidity, the environmental parameter should be ambient humidity, and the second sensor 320 should be a humidity sensor; when the fresh air outlet parameter is both fresh air humidity and fresh air temperature, the environmental parameters should be ambient humidity and ambient temperature, and the second sensor 320 should be a temperature and humidity sensor.

[0076] In the specific example of this application, the corresponding fresh air outlet comfort is mainly calculated by combining the fresh air temperature and the ambient temperature, and the corresponding fresh air outlet comfort is corrected by combining the fresh air humidity and the ambient humidity. This allows the control unit to adjust each fresh air outlet 113 according to the confirmed fresh air outlet comfort and the preset fresh air outlet comfort threshold, thereby achieving comfortable air supply to users near the mobile sub-unit 200.

[0077] Optionally, the air outlet status includes the air outlet direction and / or opening / closing state of the fresh air outlet 113. For example, the main direction of fresh air outlet 113 can be controlled according to its position on the main unit housing 110. For instance, a fresh air outlet 113 located on the front of the main unit housing 110 primarily faces users in the area in front of the main unit housing 110 when open; a fresh air outlet 113 located on the left side of the main unit housing 110 primarily faces users in the area on the left side of the main unit housing 110 when open; a fresh air outlet 113 located on the right side of the main unit housing 110 primarily faces users in the area on the right side of the main unit housing 110 when open; and a fresh air outlet 113 located at the rear side of the main unit housing 110 primarily faces users at the rear side of the main unit housing 110 when open. When the fresh air outlet 113 is completely closed, no air flows from it; when the fresh air outlet 113 is open, its opening direction is the main air outlet direction.

[0078] Optionally, such as Figure 2 , Figure 4 and Figure 5 As shown, the main unit 100 also includes an air guide assembly 140, which is located at the fresh air outlet 113. The air guide assembly 140 swings to adjust the air outlet direction and / or opening / closing state of the fresh air outlet 113. When the fresh air outlet 113 is open, by adjusting the swing of the air guide assembly 140, the fresh air passing through the fresh air outlet 113 changes direction under the guidance of the air guide assembly 140, thereby expanding the fresh air outlet range of each fresh air outlet 113 and making the air outlet pattern of each fresh air outlet 113 more flexible and diverse.

[0079] The air guide assembly 140 here can be configured with louvers to change the airflow direction; the air guide assembly 140 can also be configured with air deflectors to open and close the fresh air outlet 113 and guide the fresh air. Based on the judgment results and instructions of the control unit, the air guide assembly 140 at different fresh air outlets 113 can be controlled, ensuring that the fresh air is only blown towards the user when the comfort level meets the requirements; otherwise, it is not blown directly towards the user when the comfort level is poor. The air guide assembly 140 can be electrically connected to the control unit or wirelessly communicate with the control unit to achieve control, making the control of fresh air in the air conditioner 1000 of this invention more intelligent and convenient.

[0080] Advantageously, such as Figure 2 , Figure 3 and Figure 4 As shown, the main unit housing 110 has fresh air outlets 113 on at least the front, left and right sides, so the main unit 100 can output fresh air to at least the front area, the left area and the right area, thereby achieving fresh air output in at least 270 degrees around the main unit 100, ensuring that fresh air can be delivered to users located in different directions from the main unit 100.

[0081] Optionally, the fresh air inlet 112 is mainly located at the rear of the main unit housing 110, making the main unit 100 look more aesthetically pleasing and facilitating the installation of the fresh air hose 160 to introduce outdoor fresh air into the fresh air module 120. For example... Figure 5 and Figure 6 As shown, the fresh air hose 160 has a certain length and extensibility, which makes it easy to install at the fresh air inlet 112 and also facilitates the laying of the fresh air hose 160, thereby adapting to different installation positions of the main unit 100 and outdoor air vents at different locations in the room, making the installation of the main unit 100 more flexible.

[0082] In some embodiments of the present invention, such as Figure 7 As shown, the fresh air module 120 includes a fresh air housing 121 and a fresh air fan 122. The air inlet of the fresh air housing 121 is connected to the fresh air inlet 112, and the air outlet of the fresh air housing 121 is connected to the fresh air outlet 113. The fresh air fan 122 is installed in the fresh air housing 121 to guide fresh air from the fresh air inlet 112 to the fresh air outlet 113. The fresh air fan 122 can adjust the preset fresh air speed. Under different preset speeds, the corresponding fresh air outlet speeds are different, which will change the fresh air outlet comfort threshold. This invention can preset different fresh air outlet comfort thresholds corresponding to different preset fresh air speeds in the control unit, thereby making the control of fresh air outlet comfort more accurate and more acceptable to users.

[0083] When the fresh air fan 122 starts operating, it provides the driving force for air extraction, creating a certain negative pressure in the fresh air housing 121, allowing outdoor fresh air to enter the fresh air housing 121 through the fresh air hose 160, thereby achieving rapid air extraction. At the same time, under the constraint of the fresh air housing 121, the air discharged by the fresh air fan 122 can be guided outward along the fresh air housing 121 and flow from the air outlet to the corresponding fresh air outlet 113.

[0084] Optionally, the fresh air fan 122 can be a centrifugal fan, which can switch the direction of the air introduced into the fresh air housing 121 and discharge it outside the fresh air housing 121. The fresh air housing 121 can be a volute, and different air outlets are provided on the volute corresponding to each fresh air outlet 113, so that fresh air can be blown outward from each fresh air outlet 113.

[0085] In other examples, the fresh air fan 122 can also be an axial flow fan, a mixed flow fan, or other fans, to achieve both air intake and exhaust.

[0086] Optionally, such as Figure 7 As shown, the fresh air module 120 also includes a temperature regulation module 123, which is disposed in the fresh air housing 121 to regulate the fresh air temperature of the fresh air module 120. By adjusting the fresh air temperature, it is possible to make the calculated fresh air outlet comfort value based on the changed fresh air temperature and ambient temperature fall back into the preset comfort threshold of the fresh air outlet, thereby allowing comfortable fresh air to be directly blown to the user.

[0087] Optionally, the temperature regulation module 123 may include a heater and heat dissipation fins. During the heating process, the heater can further diffuse heat to the heat dissipation fins. When fresh air flows through the heat dissipation fins, it can be heated quickly, so that when the main unit 100 is running in heating mode, it can blow warm and comfortable fresh air to the user, thereby improving the temperature comfort of the fresh air blown to the user.

[0088] Optionally, the temperature regulation module 123 may include a thermoelectric cooler, so that when the thermoelectric cooler is working, the fresh air flowing through the cold end of the thermoelectric cooler is cooled. At this time, the air at the hot end of the thermoelectric cooler can be led to the outside by an exhaust fan, so that when the host 100 is running in cooling mode, it can blow cool and comfortable fresh air to the user, thereby improving the temperature comfort of the fresh air blown to the user.

[0089] Of course, in other examples, the temperature regulation module 123 can also be set in other forms, which will not be elaborated here. As long as the temperature regulation module 123 can adjust the temperature of the fresh air when the fresh air is supplied, it is acceptable.

[0090] Advantageously, the temperature regulation module 123 is located at the air intake end of the fresh air fan 122, so that the temperature-regulated fresh air can be buffered to a certain extent, and the temperature of the fresh air measured by the first sensor 130 is closer to the temperature of the fresh air blown into the room, and the first sensor 130 is protected from the heat of the temperature regulation module 123, thus extending the service life of the first sensor 130.

[0091] Optionally, the fresh air module 120 also includes a humidity control module (not shown), which is used to adjust the fresh air humidity of the fresh air module 120. By adjusting the fresh air humidity, it is likely that the changed fresh air humidity and the fresh air outlet comfort value calculated based on the ambient humidity will fall back into the preset comfort threshold of the fresh air outlet, thereby allowing comfortable fresh air to be blown directly to the user.

[0092] Optionally, the humidity control module includes a water tank, a humidifying membrane, and a humidifying pump. Water can be added to the water tank, and the humidifying pump sprays the water from the tank onto the humidifying membrane, thereby giving the humidifying membrane a certain moisture content. When fresh air passes through the humidifying membrane, it is humidified, thus increasing the humidity value of the fresh air blown into the room. In these examples, the humidifying membrane is preferably located at the air outlet of the fresh air housing 121 to prevent condensation from forming in the fresh air housing 121 and to ensure that the humidity value of the fresh air drawn from the fresh air housing 121 to the fresh air outlet 113 meets the standard.

[0093] Optionally, the humidity control module includes a water tank, an atomizer, and a humidification pump. The atomizer further humidifies the water drawn out by the humidification pump, thereby humidifying the incoming fresh air.

[0094] Of course, in other examples, the humidity control module can take other forms, which will not be listed here. As long as it can adjust the humidity of the fresh air when it is supplied, it is acceptable.

[0095] Optionally, such as Figure 6 and Figure 7 As shown, the fresh air module 120 also includes a fresh air filter 124, which is located at the air outlet of the fresh air housing 121, thereby ensuring that the fresh air blown towards the fresh air outlet 113 is highly clean and free of impurities and microorganisms. Alternatively, the fresh air filter 124 can be located at the air inlet of the fresh air housing 121, ensuring that the fresh air entering the fresh air housing 121 is highly clean, removing dust, microorganisms, harmful gases, etc., protecting the components in the fresh air housing 121 from dust accumulation, and extending the service life of each component.

[0096] Optionally, the fresh air filter 124 can be a multi-layer composite filter, which can effectively improve the fresh air filtration performance of the fresh air filter 124 and ensure high quality of the fresh air blown out.

[0097] Optionally, the fresh air filter 124 can also be a filter membrane or a plate-and-frame filter element, thereby facilitating the installation of the fresh air filter 124 into the fresh air housing 121. For example, in a specific example, such as Figure 6 As shown, an insertion port is formed on one side of the main unit housing 110, and an installation port is provided on the fresh air housing 121. The fresh air filter 124 is first fixed in a preset position in the fresh air housing 121 from the installation port, and then the other end of the fresh air filter 124 is inserted into the insertion port, thereby improving the convenience of replacing the fresh air filter 124 without having to remove the entire fresh air module 120 or the main unit housing 110.

[0098] Optionally, such as Figure 7 As shown, the air inlet end of the fresh air housing 121 is equipped with an air inlet valve 125 to regulate the amount of fresh air entering, and the air outlet end of the fresh air housing 121 is equipped with an air outlet valve 126 to regulate the amount of fresh air exiting, thereby effectively controlling the volume of fresh air blown into the room and ensuring that the humidity regulation module and temperature regulation module 123 can fully regulate the corresponding amount of fresh air, so that the properties of the air blown into the room from the fresh air outlet 113 can reach the preset regulation value.

[0099] In some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the main housing 110 is equipped with a docking compartment 111, in which the mobile sub-unit 200 can be accommodated. After returning to the docking compartment 111, the mobile sub-unit 200 can be stored, saving indoor space; it can also reset the coordinates of the mobile sub-unit 200 relative to the docking compartment 111; or, the mobile sub-unit 200 can be recharged upon returning to the docking compartment 111, enabling it to operate independently for an extended period after leaving the docking compartment 111. Furthermore, as... Figure 6 As shown, the fresh air module 120 is located on the upper part of the docking compartment 111. Therefore, the main housing 110 of the present invention can not only accommodate the fresh air module 120, but also accommodate the mobile sub-unit 200, thereby making the overall layout of the air conditioner 1000 more compact and occupying less indoor space.

[0100] Optionally, such as Figure 1 and Figure 4 As shown, the main unit 100 also includes a door 114, which is movable relative to the docking compartment 111 to open or close the opening of the docking compartment 111. For example, in a specific example, the door 114 can move vertically relative to the opening to open or close the docking compartment 111. When the mobile sub-unit 200 is housed in the docking compartment 111, and the door 114 closes the opening, the appearance of the main unit 100 remains consistent, making the mobile sub-unit 200 invisible from the outside. When the door 114 opens the opening, the mobile sub-unit 200 can quickly enter or exit the docking compartment 111, facilitating its movement in and out of the compartment.

[0101] In other examples, the switch door 114 can also rotate relative to the opening to open and close the opening. In yet another example, the switch door 114 can also be configured as a roller door, which opens the opening when the switch door 114 is rolled up and closes the opening when the switch door 114 is lowered.

[0102] When it is necessary to charge the mobile sub-unit 200, a power supply unit can be set up in the docking compartment 111. The power supply unit can be combined with the charging unit of the mobile sub-unit 200 to achieve charging.

[0103] Optionally, such as Figure 6 As shown, the main unit 100 also includes a heat exchanger 150 and an indoor fan. The main unit housing 110 is provided with an indoor air inlet 115 and an indoor air outlet 116. The heat exchanger 150 is arranged in the heat exchange duct above the fresh air module 120. The indoor fan can introduce indoor air from the indoor air inlet 115 into the heat exchange duct and then blow it towards the indoor air outlet 116. The heat exchanger 150 can heat or cool the air flowing through the heat exchange duct, thereby changing the temperature of the indoor air before it is discharged into the room from the indoor air outlet 116, realizing the internal circulation and temperature regulation of the indoor air, so that the overall indoor ambient temperature can be raised or lowered. Here, the heat exchanger 150 can form a heat exchange circulation system with other heat exchangers, compressors, throttling elements, etc. in the outdoor unit of the air conditioner, so as to realize the heat exchange of indoor air by the main unit 100.

[0104] Optionally, the indoor air outlet 116 is located on the side of the main unit housing 110 to prevent cold air from blowing directly on people, but also to ensure that the air after heat exchange can return to the room as soon as possible.

[0105] Advantageously, such as Figure 2 and Figure 4 As shown, the main unit 100 also includes a damper 170, which is movably disposed at the indoor air outlet 116, thereby opening or closing the indoor air outlet 116, improving the appearance of the main unit 100 when it is turned off and idle, and preventing lint and dust from entering the main unit housing 110.

[0106] Advantageously, when both an indoor air outlet 116 and a fresh air outlet 113 are provided on the side of the main unit housing 110, the damper 170 can be configured to close both the indoor air outlet 116 and the fresh air outlet 113 at the same time, thereby improving the overall appearance of the main unit 100.

[0107] Optionally, the indoor air inlet 115 is located on the rear side of the main unit housing 110, thereby separating the indoor air inlet 115 from the indoor air outlet 116 and increasing the range of indoor air circulation.

[0108] In other examples, such as Figure 6As shown, some of the fresh air outlets 113 can be located near the indoor air inlet 115 on the main unit casing 110, so that some fresh air can be drawn into the indoor air inlet 115 and then enter the indoor airflow circulation, so that fresh air can be delivered to more places in the room and the circulation of fresh air can be accelerated.

[0109] Optionally, the main unit housing 110 includes a rear housing, side panels, a top cover, a base, and a panel component 180. The left and right sides of the rear housing are respectively connected to the side panels, the top of the rear housing and the side panels are connected to the top cover, the bottom of the rear housing and the side panels are connected to the base, and the front side of the side panels is connected to the panel component 180, thereby forming a complete cavity structure in the main unit housing 110, which has sufficient space to install various components.

[0110] Optionally, some of the fresh air outlets 113 are located on the panel component 180, and the fresh air outlets 113 are located at one end near the docking chamber 111, so that the air outlet height of the fresh air outlets 113 is appropriate.

[0111] In some embodiments of the present invention, the air conditioner 1000 further includes a third sensor 330, which is disposed on the mobile sub-unit 200 to detect the distance parameters between the user and the main unit 100 and / or to detect the user's position parameters. When the mobile sub-unit 200 changes position relative to the main unit 100, the third sensor 330 can also follow the mobile sub-unit 200 in changing position relative to the main unit 100 and move to a position closer to the user, thereby accurately measuring the user's orientation and distance relative to the main unit 100.

[0112] Furthermore, the control unit of the main unit 100 determines the comfort level of the fresh air supply based on environmental parameters, distance parameters, and fresh air outlet parameters. In other words, in these examples, the distance parameter further affects the comfort level of the fresh air supply from the main unit 100. For instance, for the same fresh air outlet velocity, volume, temperature, and humidity, users at a greater distance will experience weaker and slower-moving fresh air even when the fresh air is directly blowing on them, while users at a closer distance will experience stronger and faster-moving fresh air. Therefore, the distance parameter should also be considered when adjusting the air outlet state of the fresh air outlet 113 to further improve the comfort level of the fresh air experienced by the user.

[0113] Optionally, such as Figure 1 As shown, the mobile sub-unit 200 includes a sub-unit housing 270, and a third sensor 330 is provided on the upper part of the sub-unit housing 270, thereby improving the detection range of the third sensor 330 and effectively preventing the third sensor 330 from being blocked by obstacles during the process of locating the user.

[0114] Of course, in other examples, the third sensor 330 can also be located in other positions on the sub-housing 279, such as the top of the sub-housing 270 or the middle of the sub-housing 270. No specific restrictions are imposed here.

[0115] Optionally, the third sensor 330 can be a ranging sensor. When the ranging sensor detects a user, it can measure the distance between the user and the mobile sub-unit 200, as well as the distance between the mobile sub-unit 200 and the host unit 100, thereby obtaining the distance parameters of the user relative to the host unit 100 and transmitting them to the control unit.

[0116] Optionally, the third sensor 330 can also be a lidar. The lidar can establish a cruise map and, based on the host 100 as the coordinate origin, realize the user's positioning and distance conversion, thereby obtaining the user's distance parameters and position parameters, thus providing an effective prerequisite for the control unit to further adjust the comfort of the fresh air outlet.

[0117] Optionally, the third sensor 330 may also include an infrared sensor or a vision camera, which can identify the presence of the user and measure the user's location, making the distance and / or position parameters measured by the third sensor 330 more accurate.

[0118] Optionally, the third sensor 330 communicates wirelessly with the control unit, thereby transmitting the parameters measured by the third sensor 330 to the control unit in a timely manner, so that the control unit can further adjust the air outlet status of the fresh air outlet 113 or adjust the fresh air module 120 based on the above parameters.

[0119] In the description of this invention, features defined as "first," "second," and "third" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0120] Optionally, such as Figure 1 As shown, the mobile submachine 200 also includes a mobile chassis 251 and a submachine housing 270 mounted on the mobile chassis 251. The mobile chassis 251 can drive the upper components to move, enabling the mobile submachine 200 to move flexibly and adjust its working position.

[0121] Furthermore, such as Figure 1As shown, the mobile chassis 251 is equipped with a driving component 253, which can drive the entire mobile chassis 251 to move flexibly. Specifically, the driving component 253 includes a drive wheel assembly and a caster wheel assembly. The drive wheel assembly actively drives the mobile chassis 251 to move, while the caster wheel assembly passively rotates following the drive wheel assembly. The drive wheel assembly can move without human intervention. For example, the drive wheel assembly includes a drive wheel and a wheel drive component. The wheel drive component is connected to the drive wheel, and the wheel drive component drives the drive wheel to rotate, thereby causing the drive wheel to move the entire mobile chassis 251, achieving autonomous movement of the mobile chassis 251 and making the mobile chassis 251 more stable during movement. The caster wheel assembly further supports the entire mobile chassis 251, improving the stability of the mobile chassis 251 during movement and making it easy to change direction.

[0122] Optionally, the mobile chassis 251 is also equipped with an obstacle avoidance device and a navigation device, enabling the mobile chassis 251 to navigate automatically and move intelligently.

[0123] Of course, in other examples, the mobile sub-unit 200 of the present invention may not be equipped with a mobile chassis 251, but may be separated and combined with the host unit 100 by manual movement.

[0124] Optionally, when the mobile terminal 200 detects multiple users, the control unit can determine the target user based on the distance parameters between each user and the host 100. For example, the user closest to the host 100 can be selected as the target user. Then, the control unit will determine the adjustment of the state of the fresh air outlet 113 and the operation adjustment of the fresh air module 120 based on the environmental parameters around the target user and the fresh air outlet parameters of the fresh air outlet 113.

[0125] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0126] The fresh air supply control method of the air conditioner 1000 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The structure of the air conditioner 1000 has been described in detail in the foregoing examples and will not be repeated here.

[0127] According to an embodiment of the present invention, a fresh air supply control method for an air conditioner 1000 of the foregoing examples is provided, such as... Figure 8 and Figure 9 As shown, it includes the following steps:

[0128] Step S1: Control the fresh air module 120 to output fresh air at a first preset wind speed, and the first sensor 130 detects the fresh air output parameters of the fresh air module 120.

[0129] It should be noted that at the first preset fan speed, the control unit has a preset first comfort threshold for the fresh air supply. The fresh air supply parameter here can be either the fresh air temperature or the fresh air humidity, but the fresh air temperature is the primary parameter.

[0130] Step S2: Control the mobile sub-unit 200 to move near the user, and the second sensor 320 detects the environmental parameters around the user.

[0131] The environmental parameters here can be either ambient temperature or ambient humidity, and the corresponding parameters are detected based on the fresh air outlet parameters. The mobile sub-unit 200 can be manually carried to the vicinity of the user, or it can be moved to the vicinity of the user via an intelligent navigation and recognition system; there are no restrictions here.

[0132] Step S3: Determine whether the comfort level of the fresh air outlet is within the first preset comfort threshold. The first preset comfort threshold can be adjusted according to the first preset wind speed preset after the fresh air module 120 is started, and the above relationship can be preset within the fresh air module 120.

[0133] Step S31: If so, control each fresh air outlet 113 to open and release fresh air to the outside, so that the volume of fresh air is large and all of it is comfortable fresh air. Users will feel comfortable and refreshed after blowing fresh air.

[0134] Step S32: If not, control the fresh air outlet 113 facing the user to close, while keeping other fresh air outlets 113 open, thereby effectively controlling the uncomfortable fresh air from blowing directly on the user, and instead blowing it to other parts of the room, preventing the discomfort caused by the uncomfortable fresh air blowing directly on the user.

[0135] As can be seen from the above method, the fresh air outlet control method of the air conditioner 1000 in this embodiment of the invention uses the main unit 100 and the mobile sub-unit 200 together, and judges whether the fresh air outlet comfort is within the preset threshold based on the detected environmental parameters around the user and the measured fresh air outlet parameters. Then, based on the judgment result, the air outlet state of each fresh air outlet 113 is further adjusted to deliver comfortable and fresh fresh air to users in specific locations. The fresh air delivery is highly targeted and the comfort is guaranteed.

[0136] Understandably, compared with the slow and singular fresh air supply control methods in the prior art, the fresh air supply control method of the air conditioner 1000 of the present invention has precise control and can stably deliver fresh air to users, ensuring that the fresh air received by users meets the comfort experience and can quickly meet the corresponding fresh air needs of users.

[0137] Optionally, step S1 may further include the following steps: Step S11: Send a fresh air command to the air conditioner 1000. After receiving the fresh air command, the fresh air module 120 of the air conditioner 1000 operates at a first preset wind speed.

[0138] Here, fresh air commands can be sent via remote control, voice control, mobile terminal, or control panel buttons. After receiving the fresh air command, the control unit controls the corresponding fresh air module 120 to operate and blow fresh air outward.

[0139] Optionally, after closing the fresh air outlet 113 facing the user, the following steps are also included:

[0140] Step S33: Adjust the operation of the fresh air module 120 to change the fresh air outlet parameters, and re-determine whether the fresh air outlet comfort level is within the first preset comfort threshold based on the changed fresh air outlet parameters and environmental parameters.

[0141] In a specific example, the temperature of the fresh air at the outlet can be changed, or the humidity of the fresh air at the outlet can be changed.

[0142] Step S331: If yes, control each fresh air outlet 113 to open and blow fresh air out. At this time, the fresh air after adjusting the fresh air outlet parameters can ensure the comfort of the user. Then the fresh air outlet 113 that was closed in step S32 can also be opened and blow fresh air towards the user, so that the comfortable fresh air blows directly to the user, allowing the user to quickly feel the freshness and comfort of the fresh air.

[0143] Step S332: If not, control the fresh air module 120 to increase the airflow speed, maintaining the state of the fresh air outlet 113 in step S32, so that the air conditioner 1000 maintains a normal fresh air mode with a higher airflow speed. Normal fresh air mode means that fresh air is blown into the room without targeting any specific area; the fresh air mixes with the indoor airflow but does not blow directly onto the user. If, after adjusting the fresh air outlet parameters, the requirement for comfortable fresh air delivery is still not met, then the air conditioner 1000 operates in normal fresh air mode until a shutdown command or other signal is received, at which point it exits the fresh air mode.

[0144] Optionally, after controlling each fresh air outlet 113 to open and release fresh air to the outside, the following steps are also included:

[0145] Step S333: Control the fresh air module 120 to output fresh air at a second preset wind speed, and determine whether the comfort level of the fresh air output is within the second preset comfort threshold. Step S3331: If yes, control all fresh air outlets 113 to output fresh air towards the user. It should be noted that the second preset wind speed here is greater than the first preset wind speed. That is to say, even after adjusting the fresh air output parameters, the fresh air still cannot meet the comfort requirements for blowing towards the user. Therefore, the fresh air outlets 113 that were closed in step S32 will remain closed, thereby effectively preventing uncomfortable fresh air from blowing directly on the user, and further adjustments can be made or the system can enter a normal fresh air mode.

[0146] In these examples, since the fresh air module 120 operates at a second preset wind speed, the preset comfort threshold corresponding to the second preset wind speed preset in the control unit will also change accordingly. The higher the second preset wind speed, the more comfortable the user feels when the fresh air blows to the user. At the same time, at the second preset wind speed, the fresh air can be blown a greater distance from the fresh air outlet 113. Compared with the fresh air blowing at the first preset wind speed, the fresh air at the second preset wind speed is more likely to be felt by the user, more obvious, and the fresh air circulation is faster. Therefore, after a certain period of time of fresh air outlet at the second preset wind speed, the fresh air can be exchanged with the indoor air faster and mixed more thoroughly, and the environmental parameters can be gradually adjusted. At this time, the control unit calculates the environmental parameters and fresh air outlet parameters again to confirm the comfort level of the fresh air outlet. If, after adjustment, it is within the second preset comfort threshold, it indicates that the fresh air can be blown directly to the user by increasing the wind speed and air volume. If the user feels that the fresh air outlet is comfortable and the fresh air volume is large, then all the fresh air outlets 113 that are opened in step S331 can blow fresh air directly to the user, so that the user can directly feel the comfortable and fresh fresh air on their face.

[0147] The airflow direction of the fresh air outlet 113, that is, whether the airflow is directed toward or not toward the user when the fresh air outlet 113 is open, is mainly achieved by the airflow guide component 140 in the aforementioned example.

[0148] Correspondingly, if not (the fresh air outlet comfort level is outside the second preset comfort threshold), then proceed to step S3332, and control the fresh air outlet 113 facing the user to close. Here, the fresh air outlet 113 can be fully opened and fully closed through the air guide door in the air guide component 140 in the aforementioned example.

[0149] In some embodiments of the present invention, after controlling each fresh air outlet 113 to open and release fresh air to the outside in step S31, the following steps are also included:

[0150] Step S311: Control the fresh air module 120 to increase the airflow to the third preset speed and output fresh air. Determine whether the fresh air output comfort level is within the third preset comfort threshold. If yes, execute step S312: Control each fresh air outlet 113 to output fresh air towards the user. If no, execute step S313: Control the fresh air outlet 113 facing the user to close.

[0151] The third preset wind speed here can be set higher than the first preset wind speed, and the third preset wind speed can be the same as or different from the second preset wind speed. At this time, with the preset wind speed of the fresh air outlet increased, as mentioned above, the fresh air outlets 113, which are fully opened in step S31, can also deliver fresh air faster and more efficiently. If the fresh air blows directly on a person, the feeling of fresh air will be more obvious and stronger. However, at the same time, due to the increased preset wind speed, the corresponding preset comfort threshold will change. Therefore, the fresh air outlet comfort level must be within the third preset comfort threshold to ensure a good feeling when the fresh air outlets 113 blow fresh air towards the user, thus improving the user's experience of comfortable fresh air. If the fresh air outlet comfort level is outside the third preset comfort threshold, then even if the fresh air outlets 113 blow fresh air to the user, the user will feel uncomfortable. In this case, the fresh air should not be blown directly towards the user, and the fresh air outlets 113 facing the user should be closed.

[0152] Optionally, when the mobile sub-unit 200 of the air conditioner 1000 has a third sensor 330, it can detect the distance and orientation of the user relative to the main unit 100, and further adjust the corresponding fresh air outlet parameters, air outlet status and the operation of the fresh air module 120.

[0153] Furthermore, in the aforementioned examples, it is determined whether the user is within a preset comfort threshold, and the fresh air outlet 113 is controlled based on the number of users detected by the mobile terminal 200. When multiple users are detected, the air outlet state of the fresh air outlet 113 is adjusted based on the environmental parameters around the target user closest to the host 100 and the fresh air outlet parameters as determined by the control unit.

[0154] In other words, when the mobile terminal 200 detects multiple users simultaneously, it prioritizes the user closest to the main unit 100 as the target user. It then checks the environmental parameters around the target user and whether the corresponding fresh air comfort level is within a preset comfort threshold. The mobile terminal 200 then closes the fresh air outlet 113 facing that target user, while keeping other fresh air outlets 113 open. This ensures that even if other fresh air outlets 113 are pointed at users further away, they remain open. This prevents the target user from experiencing discomfort from the fresh air while guaranteeing that fresh air is delivered to a more distant location, thus improving the efficiency of fresh air delivery.

[0155] Optionally, such as Figure 9 As shown, the control unit determines that multiple target users exist simultaneously, meaning that multiple target users are at the same distance from the host 100 but in different directions. Executing step S34, after determining, based on the steps in the aforementioned examples, that all fresh air outlets 113 facing the target users need to be closed, it controls each fresh air outlet 113 to rotate at a fourth preset wind speed and controls the fresh air outlets 113 to blow air towards the side furthest from the target users. The fourth preset wind speed is less than the first preset wind speed. Therefore, in these examples, all fresh air outlets 113 are open, but none of them blow fresh air directly towards the users, so that the users do not feel uncomfortable fresh air, but can feel the indoor air gradually becoming fresher. The air conditioner 1000 maintains normal fresh air mode operation.

[0156] Optionally, when the environmental parameter is ambient temperature, simplified control of the fresh air outlet 113 can be achieved by comparing the ambient temperature with the fresh air temperature, such as... Figure 10 As shown: Step S350, determine whether the ambient temperature is lower than the first temperature threshold; Step S351, when the ambient temperature is lower than the first temperature threshold, control the fresh air outlet 113 facing the user to close. The first temperature threshold here can be 10-20℃. When the ambient temperature is lower than 10℃, it indicates that the temperature around the user is low. At this time, the human body is more sensitive to the temperature of the fresh air. No matter how the fresh air outlet parameters are adjusted, when the fresh air blows directly to the user, the user may feel that the air temperature is low and uncomfortable. In this case, the fresh air will not be blown directly to the user.

[0157] Further, in step S352, if the ambient temperature is within the first temperature threshold and the difference between the fresh air temperature and the ambient temperature is within the first preset difference, then the fresh air outlet comfort is within the preset comfort threshold, and the fresh air outlet 113 facing the user is opened and / or each fresh air outlet 113 is controlled to outlet fresh air towards the user.

[0158] For example, if the first preset difference is greater than or equal to 35°C, then when the fresh air blows directly on the user, the comfort level of the fresh air outlet can be located within the first preset comfort threshold, the second preset comfort threshold, or the third preset comfort threshold under the aforementioned operating conditions. In this case, the user receives a comfortable fresh air with a pleasant airflow.

[0159] Furthermore, in step S353, if the ambient temperature is within the second temperature threshold and the difference between the fresh air temperature and the ambient temperature is within the second preset difference, then the fresh air comfort level is within the preset comfort threshold. In this case, the fresh air outlet 113 facing the user is opened, and / or each fresh air outlet 113 is directed towards the user to deliver fresh air. Here, the second temperature threshold is greater than the first temperature threshold, and the second preset difference is less than the first preset difference. Therefore, the ambient temperature around the user is relatively high, and the user is again in a stage sensitive to the fresh air temperature.

[0160] For example, if the second temperature threshold is 20-25℃ and the second preset difference is greater than or equal to 25℃, then when the fresh air blows directly on the user, the comfort level of the fresh air outlet can be located within the first preset comfort threshold, the second preset comfort threshold, or the third preset comfort threshold under the aforementioned operating conditions. In this case, the user receives a comfortable fresh air with a pleasant airflow.

[0161] Therefore, in this application, by directly judging the difference between the ambient temperature and the fresh air temperature, as well as the temperature threshold at which the ambient temperature is located, the comfort of the fresh air supply can be quickly determined, simplifying the control program and improving control efficiency.

[0162] Optionally, in the above examples, step S36 is also included: determining whether the air conditioner 1000 has received a signal to shut off the fresh air supply. If yes, step S361 is executed, and the fresh air module 120 stops operating; if no, step S362 is executed, maintaining the original operating state. That is to say, regardless of which of the above steps is reached, as long as the air conditioner 1000 receives a shutdown signal, the fresh air supply program will no longer continue to execute, or will terminate directly, thereby exiting the fresh air mode.

[0163] The termination signal here is similar to the procedure for the air conditioner 1000 to receive the fresh air command. For example, the termination command can be sent through a remote control, voice control, mobile terminal or control panel button. After receiving the termination command, the control unit controls the corresponding fresh air module 120 to stop running and stops blowing fresh air outward.

[0164] The following describes a specific example of the fresh air supply control method for an air conditioner 1000. In these examples, the environmental parameters are illustrated using ambient temperature as an example, and the fresh air supply parameters are illustrated using fresh air temperature as an example.

[0165] like Figure 8 , Figure 9 As shown, the fresh air outlet control method of air conditioner 1000 includes the following steps:

[0166] Step S1: Control the fresh air module 120 to output fresh air at a first preset wind speed, and the first sensor 130 detects the fresh air temperature of the fresh air module 120.

[0167] Step S2: Control the mobile sub-unit 200 to move near the user, and the second sensor 320 detects the ambient temperature around the user.

[0168] Step S3: Determine whether the comfort level of the fresh air outlet is within the first preset comfort threshold.

[0169] Step S31: If so, control each fresh air outlet 113 to open and release fresh air to the outside.

[0170] Step S311: Control the fresh air module 120 to increase the airflow to the third preset speed and determine whether the fresh air comfort level is within the third preset comfort threshold.

[0171] If so, execute step S312, then control each fresh air outlet 113 to face the user and deliver fresh air.

[0172] If not, proceed to step S313, which controls the fresh air outlet 113 facing the user to close.

[0173] Step S32: If not, control the fresh air outlet 113 facing the user to close, while keeping other fresh air outlets 113 open.

[0174] Step S33: Adjust the fresh air outlet temperature of the fresh air module 120 to increase, and re-determine whether the fresh air outlet comfort is within the first preset comfort threshold based on the changed fresh air outlet temperature and ambient temperature.

[0175] Step S331: If so, control each fresh air outlet 113 to open and release fresh air to the outside.

[0176] Step S332: If not, control the fresh air module 120 to increase the airflow speed.

[0177] Step S333: Control the fresh air module 120 to output fresh air at the second preset wind speed. The mobile sub-unit 200 detects that the number of users is greater than or equal to two. Based on the ambient temperature around the target user closest to the host 100 and the fresh air outlet temperature determined by the control unit, it is determined whether the fresh air outlet comfort level is within the second preset comfort threshold.

[0178] Step S3331: If so, control each fresh air outlet 113 to face the user and deliver fresh air.

[0179] Step S3332: If not, then control the fresh air outlet 113 facing the target user to close.

[0180] Step S34: If there are multiple target users, and after the steps in the previous examples determine that each fresh air outlet 113 facing the target user needs to be closed, then control each fresh air outlet 113 to rotate at the fourth preset wind speed, and control the fresh air outlet 113 to discharge air towards the side away from the target user. The fourth preset wind speed is less than the first preset wind speed.

[0181] Step S361: When the air conditioner 1000 receives a signal to shut off the fresh air outlet, the fresh air module 120 stops operating.
