Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, specifically providing an indoor air conditioning unit, an air conditioner, and a control method thereof. Background Technology

[0002] Related technology provides a windless airflow design for an indoor air conditioner unit. The indoor unit's air guide plate is covered with numerous air outlet holes and is closable at the air outlet. This design guides the airflow when the outlet is open, achieves windless airflow when the outlet is closed, and closes the outlet when the unit is turned off. However, this solution has the following problems:

[0003] When the air conditioner is turned off, dust can enter the interior of the air conditioner unit through multiple air outlets, causing the interior of the air conditioner unit to become dirty. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that when the air conditioner is turned off, dust will enter the interior of the air conditioner through multiple air outlets, causing the interior of the air conditioner to become dirty.

[0005] This invention provides an indoor air conditioning unit, comprising: a columnar body having an air inlet, a first air duct, and an air outlet, the air outlet being located on the circumference of the body, the air inlet being connected to the air outlet through the first air duct; an air guide plate movably disposed at the air outlet and having a first working position; and a mounting frame movably disposed on the circumference of the body and having a plurality of air outlet holes, the mounting frame and the air outlet being sequentially arranged along the axial direction of the body, and the mounting frame having a first target position;

[0006] Based on the main body operating in a windless mode, the mounting frame moves radially outward along the main body to the first target position, so that a second air duct is formed between the mounting frame and the main body. The plurality of air outlets connect the interior and exterior of the second air duct. The end of the second air duct near the air outlet has an air vent. The air guide plate moves to the first working position to guide the air jet blown out of the air outlet into the second air duct from the air vent and then blown out through the plurality of air outlets.

[0007] This invention also provides an air conditioner, including the indoor unit described in any of the above embodiments.

[0008] This invention also provides a control method for an air conditioner, comprising: based on the main body operating in a windless mode, controlling the mounting frame to move radially outward along the main body to a first target position, and controlling the air guide plate to move to a first working position, so that the air guide plate guides the air jet blown out of the air outlet to enter the second air duct from the air outlet and then be blown out through the multiple air outlet holes.

[0009] The technical solution provided in this invention embodiment, when the main body is operating in a windless mode, the mounting frame moves radially outward to a first target position, thereby constructing a second air duct between the mounting frame and the main body. Multiple air outlets connect the interior and exterior of the second air duct. The end of the second air duct near the air outlet has an air vent. The air guide plate moves to a first working position to guide the air stream blown out of the air outlet into the second air duct from the air vent, and then blown out through the multiple air outlets. This solution results in a particularly small and gentle air stream blown out through the multiple air outlets, which is difficult to detect and will not cause discomfort from the blowing, thus achieving windless blowing. Since the air guide plate in this solution does not need to be provided with air outlets for achieving windless blowing, the air guide plate can be designed to completely close the air outlet when the main body is turned off. This prevents dust from entering the interior of the main body from the air guide plate, thus preventing internal dirt accumulation. Attached Figure Description

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] The conventional technique for achieving windless airflow in this field is to cover the air guide plate with multiple air outlets, close the air outlet by the air guide plate, so that when the air stream is blown out from the multiple air outlets, the air stream is weakened and dispersed by the multiple air outlets, thereby achieving windless airflow.

[0024] The technical features described in this field, such as "the second air duct and the air outlet are arranged sequentially along the axis of the body, multiple air outlets connect the interior and exterior of the second air duct, the end of the second air duct adjacent to the air outlet has an air vent, and the air guide plate moves to the first working position to guide the air jet blown out of the air outlet into the second air duct from the air vent and then blown out through multiple air outlets," are not conventional technical means in this field. Nor are they used to solve the technical problem of how to achieve "windless blowing." Therefore, the aforementioned distinguishing technical features are not conventional technical means in this field for solving the problem of how to achieve "windless blowing."

[0025] The air conditioner indoor unit provided by this invention, such as Figures 1 to 8 As shown, it includes: a columnar body having an air inlet, a first air duct, and an air outlet 210, the air outlet 210 being located on the circumference of the body, and the air inlet being connected to the air outlet 210 through the first air duct; an air guide plate 300, movably disposed at the air outlet 210 and having a first working position; and a mounting frame 400, movably disposed on the circumference of the body and having multiple air outlet holes 410, the mounting frame 400 and the air outlet 210 being sequentially arranged in the axial direction of the body, and the mounting frame 400 having a first target position. Figure 3 and Figure 4 As shown, based on the main body operating in a windless mode, the mounting frame 400 moves radially outward along the main body to a first target position, thereby constructing a second air duct 420 between the mounting frame 400 and the main body. Multiple air outlets 410 connect the interior and exterior of the second air duct 420. The end of the second air duct 420 adjacent to the air outlet 210 has an air vent. The air guide plate 300 moves to a first working position to guide the air jets blown out of the air outlets 210 into the second air duct 420 from the air vents, and then blown out through the multiple air outlets 410. Thus, the air jets blown out through the multiple air outlets 410 are particularly small and gentle, difficult to detect, and will not cause discomfort from blowing, achieving windless blowing. In this mode, beverages that need to be cooled quickly can also be hung on the mounting frame 400, and the cold air blown out through the air outlets 410 can quickly cool the beverages.

[0026] Since this solution does not require an air outlet 410 on the air guide plate 300 to achieve windless airflow, therefore... Figure 1 and Figure 2 As shown, when the main body is turned off, the air guide plate 300 can be designed to completely close the air outlet 210, so that dust cannot enter the interior of the main body from the air guide plate 300, and thus will not cause the interior of the main body to become dirty.

[0027] In some examples, such as Figure 1 and Figure 2 As shown, since the main body 100 is in the off state, the air guide plate 300 is in the closed position and the air outlet 210 is closed. In this way, dust cannot enter the interior of the main body through the air guide plate 300 when the main body is off, and thus will not cause dirt inside the main body.

[0028] In some examples, such as Figures 2 to 8 As shown, there are two air outlets 210, each corresponding to one end of the axial direction of the main body. Each air outlet 210 is equipped with a guide vane 300, and the axial mounting frame 400 of the main body is located between the two air outlets 210. Figure 3 and Figure 4As shown, based on the main body operating in a windless mode, the second air duct 420 has air inlets at both ends of its axial direction. The two air inlets correspond one-to-one with the two air outlets 210. The air guide plate 300 inside each air outlet 210 is inclined towards the air outlet along the air outlet direction of that air outlet 210. In this way, the air guide plate 300 located inside the two air outlets 210 guides the air jets blown out of the two air outlets 210 into the second air duct 420. Thus, the pressure inside the second air duct 420 is greater than the pressure outside the second air duct 420. The air jets entering the second air duct 420 from the two air inlets will be blown out through multiple air outlets 410. The multiple air outlets 410 weaken and disperse the air jets, thereby achieving windless airflow.

[0029] In some examples, such as Figure 2 and Figure 8 As shown, the axis of the main body is along the vertical direction, the air outlet 210 faces the front of the main body, the mounting frame 400 is located on the front of the main body, the air inlet is located on the rear of the main body, the air guide plate 300 is arranged in the left-right direction and can be installed by swinging up and down, and the upper air guide plate 300 has a first sub-position, and the lower air guide plate 300 has a second sub-position. The first working position includes the first sub-position and the second sub-position. Figure 3 and Figure 4 As shown, based on the main body operating in windless mode, the mounting frame 400 moves forward to the first target position and together with the main body forms the second air duct 420. At this time, the second air duct 420 is located on the front side of the main body and has air vents at both the top and bottom. The upper air guide plate 300 swings to the first sub-position and tilts downward from back to front. At this time, the upper air guide plate 300 guides the air stream blown out from the upper air outlet 210 through the upper air vent into the second air duct 420. The lower air guide plate 300 swings to the second sub-position and tilts upward from back to front. At this time, the lower air guide plate 300 guides the air stream blown out from the lower air outlet 210 through the lower air vent into the second air duct 420.

[0030] In some examples, such as Figures 1 to 3 , Figures 5 to 8As shown, the mounting frame 400 is a frame that extends through the rear. The frame includes a first side plate 440 (such as the left side plate), a second side plate 430 (such as the front side plate), and a third side plate (such as the right side plate) connected in sequence. The main body is located between the first side plate 440 and the third side plate and is movably connected to the first side plate 440 and the third side plate in the radial direction of the main body (such as the main body and the first side plate 440 being movably connected in the front-back direction, and the main body and the second side plate 430 also being movably connected in the front-back direction; for example, the first side plate 440 and the main body are connected by a set of motor gear rack structure, and the second side plate 430 and the main body are connected by another set of motor gear rack structure. The two sets of motor gear rack structures move synchronously, so that the movement of the mounting frame 400 can be automatically controlled by the control device of the air conditioner indoor unit).

[0031] Multiple air outlets 410 are located on the first side plate 440 and / or the second side plate 430 and / or the third side plate. Alternatively, the multiple air outlets 410 may be located at least on the first side plate 440; or at least on the second side plate 430; or at least on the third side plate, etc. All of the above can achieve the purpose of this application, and their intent does not depart from the design concept of this invention. Therefore, they will not be elaborated further here, and all should fall within the protection scope of this application.

[0032] In some embodiments, such as Figures 1 to 8 As shown, multiple air outlets 410 are located on the second side plate 430 and cover the second side plate 430. In this way, the multiple air outlets 410 have a better effect on weakening and dispersing the airflow, and the airflow effect in the windless mode is better.

[0033] In some examples, such as Figures 1 to 3 , Figures 5 to 8 As shown, the main body includes a main body 100 and a head 200. The head 200 is movably disposed at the end of the main body 100 along its axial direction and has a second working position. A portion of the first air duct is located in the main body 100, and another portion is located in the head 200. The air outlet 210 is located on the circumference of the head 200, the air inlet is located in the main body 100, and the mounting frame 400 is movably disposed around the periphery of the main body 100. Figure 3 and Figure 4 As shown, based on the main body operating in a windless mode, the second air duct 420 is located on the first side (e.g., the front side) of the main body 100, and the head 200 moves to the second working position so that the air outlet 210 faces the first side (e.g., the air outlet 210 faces forward). In this scheme, the air inlet is located on the side of the main body 100 away from the second air duct 420 (e.g., the rear side).

[0034] In some examples, such as Figures 1 to 3 , Figures 5 to 8As shown, the peripheral walls of the main body 100 include a first side wall 130, a second side wall 140, a third side wall, and a fourth side wall (the air inlet is located on the fourth side wall). The first side wall 130, the second side wall 140, the third side wall, and the fourth side wall are smoothly connected in sequence. The first side plate 440 of the mounting frame 400 is movably connected to the first side wall 130 of the main body 100, and the third side plate of the mounting frame 400 is movably connected to the third side wall of the main body 100. The second side plate 430 of the mounting frame 400 is located in front of the second side wall 140 of the main body 100. This design ensures that the mounting frame 400 can stably move back and forth relative to the main body 100, resulting in high operational reliability.

[0035] In some examples, one of the head 200 and the body 100 is provided with an annular internal meshing tooth, and the other is provided with a motor and a drive gear. The drive gear is connected to the rotating shaft of the motor and meshes with the internal meshing tooth, so as to enable the head 200 to be rotatably located at the end of the body 100 (horizontally). This scheme can also realize the automatic control of the rotation of the head 200 through a control device.

[0036] In some examples, the indoor unit of the air conditioner also includes an information acquisition device. For example... Figure 5 As shown, based on the main body operating in the second operating mode, the biological information and location information of the personnel in the environment are acquired through the information acquisition device (such as acquiring physical features and location information through a camera, or acquiring temperature information and location information through an infrared temperature detection sensor, etc.). Then, according to the biological information and location information, the motor drives the head 200 to follow the personnel in the environment to blow air or (according to the biological information and location information, the motor drives the head 200 to avoid the personnel in the environment to blow air) according to the first preset position change-motor rotation angle reference table.

[0037] The second operating mode includes the wind-chasing-human mode, the wind-avoiding-human mode, and the wind-chasing-human-wind-avoiding-human mode.

[0038] like Figure 5 As shown, based on the main body operating in wind-following mode, the biological and location information of the person in the environment is acquired through the information acquisition device. Then, according to the biological and location information and following a first preset position change-motor rotation angle reference table, the motor drives the head 200 to follow the person in the environment and blow air. Figure 5 As shown, based on the main body operating in the wind-avoidance mode, the biological information and location information of the people in the environment are obtained through the information acquisition device. Then, according to the biological information and location information, the motor drives the head 200 to avoid the people in the environment and blow air according to the second preset position change-motor rotation angle reference table.

[0039] In environments with many people, a photo of a designated person can be uploaded to the air conditioner's indoor unit via a mobile phone. For example... Figure 5 As shown, based on the main body operating in wind-chasing mode, it acquires the physical characteristics and location information of people in the environment through cameras, etc., and then compares the physical characteristics with photos to determine the set person and their location information. Then, according to the location information of the set person, it controls the motor to drive the head 200 to follow the set person in the environment to blow air according to the first preset position change-motor rotation angle comparison table.

[0040] For a technical solution where the indoor unit of an air conditioner has two 200mm heads, photos of two designated personnel can be uploaded to the indoor unit via mobile phone. For example... Figure 6 As shown, based on the main body operating in wind-chasing mode, the physical characteristics and location information of all people in the environment are obtained through cameras, etc. Then, the physical characteristics are compared with two photos to determine the two set people and their location information. Then, according to the location information of the two set people, the two motors are controlled to drive the two machine heads 200 to follow the two set people in the environment to blow air (for example, the machine head 200 located above follows the relatively tall set person to blow air, and the machine head 200 located below follows the relatively short set person to blow air).

[0041] In environments with many people, photos of one or more designated individuals can be uploaded to the air conditioner's indoor unit via mobile phone. For example... Figure 5 and Figure 6 As shown, based on the main body operating in wind-avoidance mode, the physical characteristics of all people in the environment are obtained through cameras, etc. Then, based on the comparison of all physical characteristics with all photos, each set person and their location information are determined. Then, based on the location information of all set people, the motor drives the head 200 to avoid all set people in the environment and blow air according to the first preset position change-motor rotation angle comparison table.

[0042] For a technical solution where the indoor unit of an air conditioner has two 200mm heads, photos of two designated personnel can be uploaded to the indoor unit via mobile phone. For example... Figure 6As shown, based on the main body operating in the wind-chasing-wind-avoiding mode, the physical characteristics and location information of all people in the environment are obtained through cameras, etc. Then, the physical characteristics are compared with two photos to determine the two set people and their location information. Then, according to the location information of the two set people, according to the first preset position change-motor rotation angle comparison table and the second preset position change-motor rotation angle comparison table, one motor drives one head 200 to follow one set person in the environment to blow air, and another motor drives another head 200 to avoid another set person in the environment to blow air (for example, the motor located above drives the head 200 located above to follow a relatively tall set person to blow air, and the motor located below drives the head 200 located below to avoid another set person to blow air).

[0043] like Figure 1 As shown, when the main unit is turned off, the control unit 200 rotates so that the air outlet 210 faces backward, the control air guide plate 300 closes the air outlet 210, and the control mounting frame 400 moves backward until the second side plate 430 abuts against the second side wall 140, making the indoor unit of the air conditioner more aesthetically pleasing. Alternatively, it could be as follows: Figure 2 As shown, when the main body is turned off, the control head 200 rotates to the second working position with the air outlet 210 facing forward, the control air guide plate 300 closes the air outlet 210, and the control mounting frame 400 moves backward until the second side plate 430 abuts against the second side wall 140. This can also achieve the purpose of this application. Its purpose has not departed from the design concept of this invention, and will not be repeated here. All of them should fall within the protection scope of this application.

[0044] like Figure 7 As shown, when the main body is running in rapid heating mode, the control mounting frame 400 moves backward until the second side plate 430 abuts against the second side wall 140, the control head 200 rotates to the second working position, and the control air guide plate 300 swings to tilt downward from back to front to guide the air downward. Taking advantage of the fact that hot air is lighter than normal temperature air, the hot air jet will automatically float after it hits the ground, thus making the temperature of the whole room more uniform and the room heats up faster.

[0045] like Figure 8 As shown, when the main body is running in rapid cooling mode, the control mounting frame 400 moves backward until the second side plate 430 abuts against the second side wall 140, the control head 200 rotates to the second working position, and the control air guide plate 300 swings to tilt upward from back to front to guide the air upward. Taking advantage of the fact that cold air is heavier than normal temperature air, the cold air bundle is blown upward at an angle and will automatically sink, thereby achieving whole-house cooling in the shortest time.

[0046] Based on the main body operating in omnidirectional air supply mode, the control unit 200 can rotate continuously 360 degrees or rotate continuously within a set angle range. When the control unit 200 rotates continuously within the set angle range, the rotation area of ​​the control unit 200 is symmetrical about the front-back direction. At this time, the set angle can be set to approximately 90 degrees or approximately 180 degrees, etc. Both of these can achieve the purpose of this application, and their purpose does not depart from the design concept of this invention. Therefore, they will not be elaborated further here, and all should fall within the protection scope of this application.

[0047] In some examples, such as Figures 1 to 3 , Figures 5 to 8 As shown, the indoor unit of the air conditioner is set as a bed-mounted air conditioner indoor unit. The bed-mounted air conditioner indoor unit is arranged vertically in the vertical direction and is mounted on the side wall through its rear side. The fourth side wall is spaced apart from the side wall to ensure that the air inlet can stably intake air and the unit head can stably rotate horizontally.

[0048] The air conditioner provided in this embodiment of the invention (not shown in the figure) includes the indoor unit of the air conditioner described in any of the above embodiments.

[0049] This air conditioner possesses all the advantages of the indoor unit provided in any of the above embodiments, which will not be repeated here.

[0050] The control method for an air conditioner provided in this embodiment of the invention (not shown in the figure) includes: based on the main body operating in a windless mode, controlling the mounting frame 400 to move radially outward along the main body to a first target position, and controlling the air guide plate 300 to move to a first working position, so that the air guide plate 300 guides the air jet blown out of the air outlet 210 from the air outlet into the second air duct 420, and then blown out through multiple air outlets 410 (e.g., Figure 3 and Figure 4 (As shown).

[0051] In the control method of this air conditioner, when the main body is operating in a windless mode, the mounting frame 400 moves radially outward to a first target position, so that a second air duct 420 is formed between the mounting frame 400 and the main body. Multiple air outlets 410 connect the interior and exterior of the second air duct 420. The end of the second air duct 420 adjacent to the air outlet 210 has an air vent. The air guide plate 300 moves to a first working position to guide the air stream blown out of the air outlet 210 into the second air duct 420 from the air vent, and then blown out through the multiple air outlets 410. The air stream blown out through the multiple air outlets 410 is particularly small and gentle, which is difficult to detect and will not cause discomfort from blowing air, thus realizing windless blowing.

[0052] The indoor unit of the air conditioner also includes an information acquisition device and location information. Based on the main body operating in the second operating mode, the information acquisition device acquires the biological information and location information of people in the environment (such as acquiring physical features and location information through a camera, or acquiring temperature information and location information through an infrared temperature detection sensor, etc.). Then, according to the biological information, the motor drives the head 200 to follow the people in the environment to blow air, or (according to the biological information and location information, the motor drives the head 200 to avoid the people in the environment to blow air, according to the second preset position change-motor rotation angle reference table).

[0053] The second operating mode includes wind-chasing-human mode, wind-avoiding-human mode, and wind-chasing-human-wind-avoiding-human mode.

[0054] The control method of the air conditioner also includes: based on the main body operating in wind-following mode, acquiring the biological and location information of people in the environment through an information acquisition device, and then controlling the motor to drive the head 200 to follow the people in the environment and blow air according to a first preset position change-motor rotation angle reference table based on the biological and location information (e.g., Figure 5 (As shown).

[0055] The control method of the air conditioner also includes: based on the main body operating in the wind-avoidance mode, acquiring the biological and location information of people in the environment through an information acquisition device, and then controlling the motor to drive the head 200 to avoid people in the environment and blow air according to the second preset position change-motor rotation angle reference table based on the biological and location information (e.g., ...). Figure 5 (As shown).

[0056] For scenarios with many people in the environment, the control method of this air conditioner also includes: recording a photo of a designated person into the indoor unit of the air conditioner via a mobile phone; based on the unit operating in wind-tracking mode, acquiring the physical characteristics and location information of the person in the environment through a camera, and then comparing the physical characteristics with the photo to determine the designated person and their location information; then, according to the location information of the designated person, controlling the motor to drive the head 200 to follow the designated person in the environment and blow air (e.g., ...) according to a first preset position change - motor rotation angle reference table. Figure 5 (As shown).

[0057] For the technical solution of an air conditioner indoor unit having two unit heads 200, the control method of the air conditioner further includes: recording photos of two designated personnel into the air conditioner indoor unit via a mobile phone; based on the unit operating in wind-following mode, acquiring the physical characteristics and location information of all personnel in the environment through cameras, etc., then comparing all physical characteristics with the two photos to determine the two designated personnel and their location information, and then controlling two motors to drive the two unit heads 200 to follow the two designated personnel in the environment to blow air according to the first preset position change-motor rotation angle reference table based on the location information of the two designated personnel (e.g., controlling the upper unit head 200 to follow a relatively taller designated person to blow air, and the lower unit head 200 to follow a relatively shorter designated person to blow air, see [reference]). Figure 6 ).

[0058] For scenarios with many people in the environment, the control method of this air conditioner also includes: recording photos of one or more designated individuals into the indoor unit via a mobile phone; based on the unit operating in wind-avoidance mode, acquiring the physical characteristics and location information of all individuals in the environment through cameras, etc., then comparing all physical characteristics with all photos to determine each designated individual and their location information, and then controlling the motor to drive the unit head 200 degrees to avoid all designated individuals in the environment and blow air (e.g., according to the location information of all designated individuals, according to the first preset position change - motor rotation angle reference table) to avoid all designated individuals in the environment (e.g., ... Figure 5 and Figure 6 (As shown).

[0059] For the technical solution of an air conditioner indoor unit having two unit heads 200, the control method of the air conditioner further includes: recording photos of two designated personnel into the air conditioner indoor unit via a mobile phone; based on the main body operating in a wind-following-wind-avoiding-person mode, acquiring the physical characteristics and location information of all personnel in the environment through cameras, etc., then comparing all physical characteristics with the two photos to determine the two designated personnel and their location information, and then, according to the location information of the two designated personnel and according to the first preset position change-motor rotation angle comparison table and the second preset position change-motor rotation angle comparison table, controlling one motor to drive one unit head 200 to follow one designated person in the environment to blow air, and controlling the other motor to drive another unit head 200 to avoid another designated person in the environment to blow air (e.g., controlling the upper motor to drive the upper unit head 200 to follow a relatively tall designated person to blow air, and controlling the lower motor to drive the lower unit head 200 to avoid another relatively short designated person to blow air (e.g., controlling the upper motor to drive the upper unit head 200 to follow a relatively tall designated person to blow air, and controlling the lower motor to drive the lower unit head 200 to avoid another designated person to blow air (e.g., controlling the lower motor to drive the lower unit head 200 to avoid another relatively short designated person to blow air (e.g.)). Figure 6 (As shown).

[0060] The control method of this air conditioner also includes: based on the main unit being turned off, controlling the unit head 200 to rotate so that the air outlet 210 faces backward, controlling the air guide plate 300 to close the air outlet 210, and controlling the mounting frame 400 to move backward until the second side plate 430 abuts against the second side wall 140, thus making the indoor unit of the air conditioner more aesthetically pleasing (e.g., Figure 1 (As shown). Alternatively, the control method of the air conditioner may also include: when the main unit is turned off, the control head 200 is rotated to the second working position with the air outlet 210 facing forward, the control guide plate 300 is closed to close the air outlet 210, and the control mounting frame 400 is moved backward until the second side plate 430 abuts against the second side wall 140 (as shown). Figure 2 As shown, the purpose of this application can also be achieved. Its purpose has not departed from the design concept of this invention, and will not be repeated here. All of them should fall within the protection scope of this application.

[0061] The control method of the air conditioner also includes: based on the main body operating in rapid heating mode, controlling the mounting frame 400 to move backward until the second side plate 430 abuts against the second side wall 140 (i.e., controlling the mounting frame 400 to move backward to the initial position), controlling the unit head 200 to rotate to the second working position (at this time, the air outlet 210 faces forward), and controlling the air guide plate 300 to swing to tilt downward from back to front (e.g. Figure 7 As shown, the air is tilted downwards and guided by the airflow. Taking advantage of the fact that hot air is lighter than normal air, the hot air jet will automatically rise after it hits the ground, thus making the temperature of the whole room more uniform and the room heats up faster.

[0062] The control method of the air conditioner also includes: based on the main body operating in rapid cooling mode, controlling the mounting frame 400 to move backward until the second side plate 430 abuts against the second side wall 140 (i.e., controlling the mounting frame 400 to move backward to the initial position), controlling the unit head 200 to rotate to the second working position (at this time, the air outlet 210 faces forward), and controlling the air guide plate 300 to swing to tilt upward from back to front (e.g. Figure 8 As shown, the air is tilted upwards and guided by the principle that cold air is heavier than normal air. After the cold air is tilted upwards, it will automatically sink, thus achieving whole-house cooling in the shortest possible time.

[0063] The control method of the air conditioner also includes: based on the main body operating in an all-around air supply mode, controlling the unit head 200 to rotate continuously 360 degrees or controlling the unit head 200 to rotate continuously within a set angle range. When the unit head 200 rotates continuously within the set angle range, the rotation area of ​​the unit head 200 is symmetrical about the front and rear directions. At this time, the set angle can be set to about 90 degrees or about 180 degrees, etc. All of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention. They will not be elaborated here, and all should fall within the protection scope of this application.

[0064] In summary, according to the technical solution provided by the embodiments of the present invention, when the main body operates in the no-wind-feeling mode, the mounting frame moves radially outward along the main body to the first target position, so that a second air duct is formed between the mounting frame and the main body, a plurality of air outlet holes communicate the interior and the exterior of the second air duct, the end of the second air duct adjacent to the air outlet is provided with a vent, and the air deflector moves to the first working position, so as to guide the air flow blown out from the air outlet to enter the second air duct through the vent and then be blown out through the plurality of air outlet holes. With this solution, the air flow blown out through the plurality of air outlet holes is extremely small and extremely soft, barely perceptible, and will not cause blowing discomfort, realizing no-wind-feeling air supply. Since there is no need to arrange air outlet holes for realizing no-wind-feeling air supply on the air deflector in this solution, the air deflector can be designed to completely close the air outlet when the main body is shut down, so that dust cannot enter the interior of the main body through the air deflector, and thus the interior of the main body will not be contaminated.
