Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and specifically provides an indoor air conditioning unit. Background Technology

[0002] Existing air conditioner indoor units consist of a main body and an air guide plate. The main body has an air outlet, and the air guide plate is hinged to the air outlet and covered with numerous small air passage holes. When the indoor unit operates in a windless mode, the air guide plate closes the air outlet, and the airflow inside the main body is weakened by being blown out through these small air passage holes, achieving windless airflow. Because of the windless mode, the air resistance created by the air guide plate on the airflow is particularly high. In this mode, the indoor unit cannot output high-speed airflow; otherwise, the airflow passing through the air guide plate would generate significant wind noise. This is the main reason why existing air conditioner indoor units cannot operate at high power and high airflow in windless mode, and thus cannot achieve rapid heat exchange in the indoor environment. Summary of the Invention

[0003] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that the existing air conditioner indoor unit cannot operate at high power and large air volume when it is in windless mode, and thus cannot achieve rapid heat exchange in the indoor environment.

[0004] This invention provides an indoor air conditioner unit, including a control device, a main body, and an air guide plate. The main body has an air inlet, an air duct, and an air outlet. The air outlet is connected to the air inlet through the air duct. The air guide plate is movably disposed at the air outlet. The air outlet includes a side air outlet area, and the air guide plate includes a side air guide plate. The side air outlet area is located on the side of the main body, and the side air guide plate is movably disposed in the side air outlet area and has a first working position.

[0005] Based on the main body operating in a windless mode, the control device controls the side air guide plate to move to the first working position to open the side air outlet area, controls the formation of an air duct inside the air duct that flows from the air inlet to the side air outlet area, and the side air guide plate guides the air duct blown out from the side air outlet area to blow towards the outer rear part of the side air outlet area.

[0006] This invention also provides an air conditioner, including the indoor unit described in any of the above embodiments.

[0007] The technical solution provided in this invention operates in a windless mode. The side air guide plate moves to the first working position to open the side air outlet area and guides the airflow from the side air outlet area toward the outer rear of the side air outlet area. Since the people in the indoor environment are not located at the side rear of the air conditioner unit, and the airflow from the air conditioner unit blows towards the side wall first, it is blocked by the side wall, resulting in a significant reduction in wind speed, air volume, and blowing distance, and continues to blow along the side of the side wall. Therefore, it is difficult for the airflow to reach the location of the people in the indoor environment. Even if the people are located on the side of the air conditioner unit and are relatively close to it, there will still be a certain distance between the people and the side wall. Since the airflow has been blocked by the side wall, resulting in a reduction in speed, air volume, and blowing distance, and continues to blow along the side of the side wall, the airflow that can reach the vicinity of the people in this case is particularly small and gentle, making it difficult to detect and not causing discomfort. It is comparable to the blowing experience of a windless air conditioner and can be used as a windless air conditioner. In this configuration, the indoor unit of the air conditioner operates in a windless mode, with the air deflector opening to the side air outlet. The air deflector does not create significant wind resistance to the airflow, thus allowing the indoor unit to operate in a windless mode and achieve high-power, high-volume operation for rapid heat exchange in the indoor environment.

[0008] After the indoor unit of an air conditioner is installed (especially a floor-standing air conditioner), the rear of the indoor unit faces the side wall. People in the indoor environment are located to the left, front, or rear of the indoor unit (for wall-mounted air conditioners, people may also be located in front of and below the wall-mounted unit), not to the side or rear of the indoor unit. This is the main reason why those skilled in the art do not set the indoor unit of an air conditioner to blow air towards the rear or the side and rear. Therefore, setting the indoor unit of an air conditioner to blow air towards its side and rear is not a conventional technical means in this field, nor is it a conventional technical means in this field to solve the problem of how to achieve windless airflow.

[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] After the indoor unit of an air conditioner is installed (especially a floor-standing air conditioner), the rear of the indoor unit faces the side wall. People in the indoor environment are located to the left, front, or rear of the indoor unit (for wall-mounted air conditioners, people may also be located in front of and below the wall-mounted unit), not to the side or rear of the indoor unit. This is the main reason why those skilled in the art do not set the indoor unit of an air conditioner to blow air towards the rear or the side and rear. Therefore, setting the indoor unit of an air conditioner to blow air towards its side and rear is not a conventional technical means in this field, nor is it a conventional technical means in this field to solve the problem of how to achieve windless airflow.

[0024] The air conditioner indoor unit provided by this invention, such as Figures 1 to 9 As shown, the device includes a control unit, a vertical columnar main body 100, and an air guide plate 200. The main body 100 has an air inlet, an air duct, and an air outlet 110. The air duct is located inside the main body 100, and the air outlet 110 is connected to the air inlet through the air duct. The air guide plate 200 is movably disposed at the air outlet 110. The air outlet 110 includes a side air outlet area, and the air guide plate 200 includes a side air guide plate. The side air outlet area is located on the side of the main body 100, and the side air guide plate is movably disposed in the side air outlet area and has a first working position. Figure 2 As shown, based on the main body 100 operating in the windless mode, the control device controls the side air guide plate to move to the first working position to open the side air outlet area, and controls the formation of an air duct inside the air duct that flows from the air inlet to the side air outlet area. At this time, the side air guide plate guides the air duct blown out from the side air outlet area to blow towards the outer rear of the side air outlet area.

[0025] The indoor unit of this air conditioner, with its main body 100 operating in a windless mode, moves its side air guide plate to the first working position, opening the side air outlet area and guiding the airflow from the side air outlet area towards the outer rear of the side air outlet area. Since the people in the indoor environment are not located at the side rear of the air conditioner's indoor unit, and the airflow from the indoor unit first blows towards the side wall, where it is blocked by the side wall, resulting in a significant reduction in wind speed, air volume, and blowing distance, and continues to blow along the side of the side wall, it is difficult for the airflow to reach the location of the people in the indoor environment. Even if the people are located on the side of the air conditioner's indoor unit and are relatively close to it, there will still be a certain distance between the people and the side wall. Because the airflow has already been blocked by the side wall, resulting in a reduction in speed, air volume, and blowing distance, and continues to blow along the side of the side wall, the airflow that can reach the vicinity of the people's location in this case is particularly small and gentle, making it difficult to detect and not causing any discomfort from the blowing. The blowing experience is comparable to that of a windless air conditioner, and it can be used as a windless air conditioner. In this configuration, the indoor unit of the air conditioner operates in a windless mode, with the air deflector opening to the side air outlet. The air deflector does not create significant wind resistance to the airflow, thus allowing the indoor unit to operate in a windless mode and achieve high-power, high-volume operation for rapid heat exchange in the indoor environment.

[0026] The control device is required to control the air guide plate of the indoor air conditioner, and therefore it is considered part of the indoor air conditioner unit. However, the control device can be installed in the main body, at the terminal, or at the outdoor air conditioner unit, etc. All of these 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. Military camps are within the protection scope of this application.

[0027] In some examples, the air guide vanes are connected to the motors in a one-to-one transmission manner, and the motors control the air guide vanes independently in a one-to-one manner.

[0028] In some examples, such as Figure 2 As shown, the side air outlet area includes a left air outlet area 111 and a right air outlet area 112. The side air guide plate 200 includes a left air guide plate 210 and a right air guide plate 220. The left air outlet area 111 is located on the left side of the main body 100, and the right air outlet area 112 is located on the right side of the main body 100. The left air guide plate 210 is movably disposed in the left air outlet area 111, and the right air guide plate 220 is movably disposed in the right air outlet area 112. The left air guide plate 210 has a first sub-position, and the right air guide plate 220 has a second sub-position. The first working position includes both the first and second sub-positions. Figure 2 As shown, based on the main body 100 operating in a windless mode, the control device controls the left air guide plate 210 to move to the first sub-position to open the left air outlet 111, and controls the right air guide plate 220 to move to the second sub-position to open the right air outlet 112. The control device forms an airflow from the air inlet through the air duct to the left air outlet 111 and the right air outlet 112. At this time, the left air guide plate 210 guides the airflow from the left air outlet 111 to blow towards the left rear of the left air outlet 111, and the right air guide plate 220 guides the airflow from the right air outlet 112 to blow towards the right rear of the right air outlet 112.

[0029] The main unit 100 operates in a windless mode. The left air guide plate 210 guides the airflow from the left air outlet 111 towards the rear left side of the main unit 100 and towards the wall. The right air guide plate 220 guides the airflow from the right air outlet 112 towards the rear right side of the main unit 100 and towards the wall. Both airflows are blocked by the side wall, reducing their speed, volume, and distance. In this configuration, the main unit 100 operates in a windless mode, with both the left and right air outlets 111 and 112 open. Therefore, the indoor unit of this air conditioner operates in a windless mode, allowing for higher power and greater airflow, resulting in faster and more efficient heat exchange in the indoor environment.

[0030] In some embodiments, such as Figure 2As shown, when the left air guide plate 210 is in the first sub-position, the left air guide plate 210 is arranged tilted to the left from front to back; when the right air guide plate 220 is in the second sub-position, the right air guide plate 220 is arranged tilted to the right from front to back.

[0031] In some embodiments, such as Figures 1 to 9 As shown, both the left-side air guide plate 210 and the right-side air guide plate 220 include multiple independently controlled motors (which may be multiple left-side air guide plates 210 connected to multiple first motors, with each first motor independently controlling one of the multiple left-side air guide plates 210; and multiple right-side air guide plates 220 connected to multiple second motors, with each second motor independently controlling one of the multiple right-side air guide plates 220; the motors include multiple first motors and multiple second motors). The multiple left-side air guide plates 210 and multiple right-side air guide plates 220 are sequentially arranged circumferentially around the main body 100. Each left-side air guide plate 210 is vertically arranged and hinged to the main body 100 at its upper and lower ends. Similarly, each right-side air guide plate 220 is vertically arranged and hinged to the main body 100 at its upper and lower ends. Figure 2 As shown, when the multiple left-side air guide plates 210 are in the first sub-position, each left-side air guide plate 210 is arranged tilted to the left from front to back; when the multiple right-side air guide plates 220 are in the second sub-position, each right-side air guide plate 220 is arranged tilted to the right from front to back.

[0032] It can be that multiple left-side air guide plates 210 and multiple right-side air guide plates 220 are arranged symmetrically; or it can be that multiple left-side air guide plates 210 and multiple right-side air guide plates 220 are arranged asymmetrically; both of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention, so they will not be described in detail here, and all should fall within the protection scope of this application.

[0033] Multiple left-side air guides 210 are located in the first sub-position: this can be that the multiple left-side air guides 210 have the same swing angle relative to their respective closed positions; or the multiple left-side air guides 210 have not exactly the same swing angle relative to their respective closed positions; or the multiple left-side air guides 210 have completely different swing angles relative to their respective closed positions, etc.

[0034] Multiple right-side air guides 220 are located in the second sub-position: this can be that the multiple right-side air guides 220 have the same swing angle relative to their respective closed positions; or the multiple right-side air guides 220 have not exactly the same swing angle relative to their respective closed positions; or the multiple right-side air guides 220 have completely different swing angles relative to their respective closed positions, etc.

[0035] 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 repeated here, and should all fall within the protection scope of this application.

[0036] Alternatively, the left air guide plate 210 and the right air guide plate 220 may each include one; alternatively, the left air guide plate 210 may include one and the right air guide plate 220 may include multiple; or the left air guide plate 210 may include multiple and the right air guide plate 220 may include one, 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.

[0037] In some examples, the left air guide plate 210 also has a third sub-position, and the right air guide plate 220 also has a fourth sub-position. For example... Figure 3 As shown, based on the main body 100 operating in gentle wind mode, the control device controls the left air guide plate 210 to move to the third sub-position to open the left air outlet 111, and controls the right air guide plate 220 to move to the fourth sub-position to open the right air outlet 112. The control device forms an air duct that flows from the air inlet through the air duct to the left air outlet 111 and the right air outlet 112. At this time, the left air guide plate 210 guides the air duct blown out from the left air outlet 111 towards the front right side of the left air outlet 111, and the right air guide plate 220 guides the air duct blown out from the right air outlet 112 towards the front left side of the right air outlet 112. The air ducts guided by the left air guide plate 210 and the air ducts guided by the right air guide plate 220 converge at the front of the main body 100 and turbulent with each other, thus achieving gentle air delivery. In this design, both the left air outlet zone 111 and the right air outlet zone 112 are in the open state, allowing for high-power, high-volume operation and achieving rapid heat exchange in the indoor environment under gentle breeze mode.

[0038] Multiple left-side air guides 210 are located in the third sub-position: This can be because the multiple left-side air guides 210 have the same swing angle relative to their respective closed positions; or the multiple left-side air guides 210 have not exactly the same swing angle relative to their respective closed positions; or the multiple left-side air guides 210 have completely different swing angles relative to their respective closed positions, etc.

[0039] Multiple right-side air guides 220 are located in the fourth sub-position: This can be because the multiple right-side air guides 220 have the same swing angle relative to their respective closed positions; or the multiple right-side air guides 220 have not the same swing angle relative to their respective closed positions; or the multiple right-side air guides 220 have completely different swing angles relative to their respective closed positions, etc.

[0040] 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 repeated here, and should all fall within the protection scope of this application.

[0041] In some embodiments, such as Figure 3 As shown, when the multiple left-side air guide plates 210 are in the third sub-position, the left-side air guide plate 210 at the rear is arranged tilted to the right from front to back, and the remaining left-side air guide plates 210 are arranged tilted to the left from front to back. When the multiple right-side air guide plates 220 are in the fourth sub-position, the right-side air guide plate 220 at the rear is arranged tilted to the left from front to back, and the remaining right-side air guide plates 220 are arranged tilted to the right from front to back.

[0042] In some embodiments, such as Figures 1 to 9 As shown, the air outlet 110 also includes a front air outlet area 113, which is located at the front of the main body 100. The air guide plate 200 also includes a front air guide plate 230, which is movably disposed in the front air outlet area 113. The front air guide plate 230 has a second working position and a second closed position. Figure 2 As shown, when the main body 100 is operating in windless mode, the front air guide plate 230 moves to the second closed position to close the front air outlet 113, that is, the front air outlet 113 needs to be closed in windless mode. Figure 3 As shown, based on the main body 100 operating in gentle breeze mode, the control device controls the front air guide plate 230 to move to the second working position, opening the front air outlet zone 113. An airflow stream is also formed inside the control duct, flowing from the air inlet through the duct to the front air outlet zone 113. At this time, the front air guide plate 230 guides the airflow stream from the front air outlet zone 113 towards the front of the front air outlet zone 113. Furthermore, the airflow stream guided by the front air guide plate 230, the airflow stream guided by the left air guide plate 210, and the airflow stream guided by the right air guide plate 220 converge at the front of the main body 100, causing mutual turbulence and achieving gentle airflow. In this scheme, the left air outlet zone 111, the right air outlet zone 112, and the front air outlet zone 113 are all in the open state, which can better achieve rapid heat exchange in the indoor environment under gentle breeze mode.

[0043] In some embodiments, such as Figures 1 to 9As shown, the front guide vanes 230 include two independently controlled vanes (which may be connected to two third motors in a one-to-one transmission configuration, with each motor independently controlling one of the vanes). The two front guide vanes 230 are sequentially arranged circumferentially around the main body 100, each vane 230 being vertically arranged and hinged to the main body 100 at its upper and lower ends. Based on the front guide vanes 230 being in the second working position, the control device controls the left-side vane 230 to tilt from front to back to the left, and controls the right-side vane 230 to tilt from front to back to the right, thus achieving a gentler airflow. The motors include a first motor, a second motor, and a third motor. The two front guide vanes 230 are arranged symmetrically.

[0044] Of course, the front air guide plate 230 may include one; it may also include three, four or five such plates arranged sequentially in the circumferential direction of the main body 100; all of the above can achieve the purpose of this application, and their purpose has not departed from the design concept of this invention, and will not be elaborated here, and should all fall within the protection scope of this application.

[0045] In some examples, such as Figure 4 As shown, with the main body 100 in the off mode, the control device controls the left air guide plate 210 to close the left air outlet area 111 (or, the control device controls multiple first motors to operate, causing the left air guide plate 210 to close the left air outlet area 111), controls the right air guide plate 220 to close the right air outlet area 112 (or, the control device controls multiple second motors to operate, causing the right air guide plate 220 to close the right air outlet area 112), and controls the front air guide plate 230 to close the front air outlet area 113 (or, the control device controls two third motors to operate, causing the front air guide plate 230 to close the front air outlet area 113). This can prevent dust, mosquitoes, and rats from entering the air duct from the front air outlet area 113, the left air outlet area 111, and the right air outlet area 112.

[0046] In some examples, such as Figure 5As shown, based on the main body 100 operating in side air outlet mode, the control device controls the air guide plate (i.e., the front air guide plate 230) to close the front air outlet area 113, and (controls the left air guide plate 210 and the right air guide plate 220) to partially or fully open at least one of the left air outlet area 111 and the right air outlet area 112 (which can be: the front air outlet area 113 is completely closed, the left air outlet area 111 is fully open, and the right air outlet area 112 is completely closed, fully open, or partially open; or the front air outlet area 113 is completely closed, the left air outlet area 111 is partially open, and the right air outlet area 112 is completely closed, fully open, or partially open; or the front air outlet area 113 is completely closed, the left air outlet area 111 is completely closed, and the right air outlet area 112 is fully open or partially open, 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, and will not be elaborated here, and should all fall within the protection scope of this application). In some examples, based on the main body 100 operating in side-outlet mode, the control device controls the left air guide plate 210 on the rearmost side to open and the other left air guide plates 210 to close. The control device also controls the right air guide plate 220 on the rearmost side to open and the other right air guide plates 220 to close.

[0047] In some examples, such as Figure 6 As shown, based on the main body 100 operating in front-outlet mode, the control device controls the left air guide plate 210 to close the left air outlet area 111, controls the right air guide plate 220 to close the right air outlet area 112, and controls the front air guide plate 230 to partially or fully open the front air outlet area 113. In front-outlet mode, the air delivery distance of the front air outlet area 113 is longer. In some examples, based on the main body 100 operating in front-outlet mode, the control device controls the left air guide plate 210 to close the left air outlet area 111, controls the right air guide plate 220 to close the right air outlet area 112, and controls both front air guide plates 230 to fully open the front air outlet area 113.

[0048] In some examples, such as Figure 7As shown, based on the main body 100 operating in unidirectional air supply mode, the control device controls the left air guide plate 210 to move to the first set working position corresponding to the target air supply direction to open the left air outlet area 111, controls the right air guide plate 220 to move to the second set working position corresponding to the target air supply direction to open the right air outlet area 112, and controls the front air guide plate 230 to move to the third set working position corresponding to the target air supply direction to open the front air outlet area 113. At this time, the left air guide plate 210 guides the air stream blown from the left air outlet area 111 to blow along the target air supply direction, the right air guide plate 220 guides the air stream blown from the right air outlet area 112 to blow along the target air supply direction, and the front air guide plate 230 guides the air stream blown from the front air outlet area 113 to blow along the target air supply direction. It is possible that the target air supply direction is from back to front. At this time, the main body 100 operates in a unidirectional air supply mode. The air jet blown out from the left air outlet 111 is guided by the left air guide plate 210 to supply air to the front of the left air outlet 111. The air jet blown out from the right air outlet 112 is guided by the right air guide plate 220 to supply air to the front of the right air outlet 112. The air jet blown out from the front air outlet 113 is guided by the front air guide plate 230 to supply air to the front of the front air outlet 113.

[0049] In some examples, such as Figure 8 As shown, based on the main body 100 operating in omnidirectional air supply mode, the control device controls the air guide plates to swing 85 to 95 degrees relative to their closed position, realizing omnidirectional air supply of the main body 100 towards the front, left, and right sides. Alternatively, based on the main body 100 operating in omnidirectional air supply mode, the control device controls each air guide plate to swing 85 degrees relative to its closed position; or based on the main body 100 operating in omnidirectional air supply mode, the control device controls each air guide plate to swing 90 degrees relative to its closed position; or based on the main body 100 operating in omnidirectional air supply mode, the control device controls each air guide plate to swing 95 degrees relative to its closed position, 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, and will not be elaborated further here, all of which should fall within the protection scope of this application.

[0050] In some examples, the indoor unit of the air conditioner also includes a detection device electrically connected to the control unit, the detection device being configured to acquire the location information of personnel. For example... Figure 9 As shown, based on the main body 100 operating in wind-avoidance mode, the control device controls the air guide plate (which can be the control device controlling the motor according to the first preset position information-motor swing angle reference table, so that the air guide plate) to close the part of the air outlet 110 facing the location of the person and open the part of the air outlet 110 not facing the location of the person, thereby realizing automated wind-avoidance. Figure 9As shown, based on the main body 100 operating in the wind-chasing mode, the control device controls the air guide plate according to the position information (or the control device controls the motor according to the second preset position information-motor swing angle reference table, so that the air guide plate) to open the part of the air outlet 110 facing the position of the person and close the part of the air outlet 110 not facing the position of the person, so as to realize automated wind-chasing and blowing.

[0051] In some examples, the indoor unit of the air conditioner also includes an audio detection device electrically connected to the control device, which is configured to acquire audio information. Based on the main body 100 operating in dynamic mode, the control device controls the air guide vane to swing according to the audio information (or, the control device controls the motor according to a preset audio information-motor swing angle lookup table, causing the air guide vane to swing). For example, when the main body 100 is operating in dynamic mode, if a song or music is played through a device such as a smart speaker, the audio detection device acquires the audio information of the played song or music, and the control device controls the motor according to the preset audio information-motor swing angle lookup table, causing the air guide vane, which is in the open state, to swing dynamically.

[0052] In some examples, such as Figures 1 to 9 As shown, the main body 100 has a protruding surface 120 that protrudes forward, and the air outlet 110 is located on the protruding surface 120 and extends backward from the front of the main body 100 to the left and right sides of the main body 100, so that the main body 100 has a better blowing effect in the gentle wind mode and the all-round air supply mode.

[0053] In some embodiments, such as Figures 1 to 9 As shown, the main body 100 is cylindrical or elliptical and symmetrical, and the air outlet 110 has an arc of not less than 170 degrees in the circumferential direction of the main body 100. This allows the main body 100 to operate in an omnidirectional air supply mode, achieving full-angle air supply from the air outlet 110 within a range of not less than 170 degrees in the circumferential direction of the main body 100. This not only results in better temperature consistency across different locations in the indoor environment but also provides a better airflow experience for the user. In some embodiments, the arc of the air outlet 110 in the circumferential direction of the main body 100 is set to approximately 180 degrees.

[0054] In some examples, such as Figures 1 to 9As shown, the air inlet is located at the rear of the main body 100. An impeller 300 is installed within the air duct. A protective structure 400 is provided between the impeller 300 and the air outlet 110. The protective structure 400 is designed to allow airflow while preventing fingers from passing through, thus avoiding injury from fingers touching the impeller 300 after the air guide plate is opened and extending from the air outlet 110 into the air duct. The protective structure 400 can be a protective net, grille, or frame arranged vertically in the vertical direction. All of these 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 and should all fall within the protection scope of this application.

[0055] In some examples, the indoor unit of the air conditioner is set as a floor-standing indoor unit.

[0056] 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.

[0057] This air conditioner possesses all the advantages of the indoor unit provided in any of the above embodiments, which will not be elaborated further here.

[0058] In some examples, the indoor unit of the air conditioner is a floor-standing indoor unit, and the air conditioner includes an outdoor unit and a floor-standing indoor unit.

[0059] In summary, the technical solution provided by the embodiments of the present invention operates in a windless mode. The side air guide plate moves to the first working position to open the side air outlet area and guides the air jets blown from the side air outlet area toward the outer rear of the side air outlet area. Since the people in the indoor environment are not located at the side rear of the air conditioner unit, and the air jets blown from the air conditioner unit first blow toward the side wall, are blocked by the side wall, resulting in a significant reduction in wind speed, air volume, and blowing distance, and continue to blow along the side of the side wall, it is difficult for the air jets to reach the location of the people in the indoor environment. Even if the people are located on the side of the air conditioner unit and are relatively close to the air conditioner unit, there will still be a certain distance between the people and the side wall. Since the air jets have already been blocked by the side wall, resulting in a reduction in speed, air volume, and blowing distance, and continue to blow along the side of the side wall, the air volume of the air jets that can reach the vicinity of the people's location is particularly small and very gentle, making it difficult to detect and not causing any discomfort from the blowing. It is comparable to the blowing experience of windless air conditioning and can be used as windless air conditioning. In this configuration, the indoor unit of the air conditioner operates in a windless mode, with the air deflector opening to the side air outlet. The air deflector does not create significant wind resistance to the airflow, thus allowing the indoor unit to operate in a windless mode and achieve high-power, high-volume operation for rapid heat exchange in the indoor environment.
