Description

Technical Field

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

[0002] With the development of science and technology and the improvement of people's living standards, the requirements for air conditioners have evolved from simple cooling and heating functions to energy saving, comfort, and health. Current air conditioner manufacturers are paying increasing attention to the comfort of the human body when the air is blown out, and have introduced functions such as "top airflow for cooling and bottom airflow for heating." To avoid the air conditioner blowing directly on the human body, micro-perforated air outlets and various air diffusion functions have been introduced.

[0003] Existing technologies for comfort air supply and air guide plate structures include micro-perforated air outlets, flexible air guide plates, and air diffusion components. Micro-perforated air outlets significantly impede airflow. Flexible air guide plates require high-quality materials and cannot achieve precise control over material deformation. Air diffusion components, in order to achieve a wide range of air diffusion adjustment angles, have relatively complex adjustment structures. Summary of the Invention

[0004] The main objective of this invention is to provide a control method for an indoor unit and an air conditioner to solve the problem of airflow directly blowing onto people in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, an indoor unit is provided.

[0012] Furthermore, the first magnetic component is fixedly connected to the upper air guide assembly, and the second magnetic component is movably connected to the outer shell.

[0053] Combination Figures 1 to 11 As shown in the specific embodiment of this application, an indoor unit is provided.

[0054] Specifically, the indoor unit 1 includes: a base shell 10 having an air outlet 100; an air guide mechanism 20 rotatably disposed at the air outlet 100, at least a portion of which has an air outlet channel 200; an oscillation assembly 30 disposed within the air outlet channel 200; and a magnetic suction assembly 40 connected to the air guide mechanism 20, having a blocking position for blocking the air outlet channel 200 and a clearance position for avoiding the air outlet channel 200; wherein, when the magnetic suction assembly 40 is in the clearance position, a portion of the airflow blown from the air outlet 100 is blown out of the base shell 10 through the air outlet channel 200.

[0055] In this embodiment, the indoor unit 1 includes a bottom shell 10, an air guide mechanism 20, an oscillation component 30, and a magnetic suction component 40. The bottom shell 10 has an air outlet 100. The air guide mechanism 20 is rotatably disposed at the air outlet 100. At least a portion of the air guide mechanism 20 is provided with an air outlet channel 200. The oscillation component 30 is disposed within the air outlet channel 200. The magnetic suction component 40 is connected to the air guide mechanism 20. The magnetic suction component 40 has a blocking position for blocking the air outlet channel 200 and a yielding position for yielding to the oscillation component 30 in the air outlet channel 200. When the magnetic suction component 40 is in the yielding position, part of the airflow blown from the air outlet 100 passes through the oscillation component 30 in the air outlet channel 200 and is blown out of the bottom shell 10, thereby achieving a gentle breeze effect, solving the problem of the airflow of the indoor unit 1 blowing directly onto people, and improving the airflow comfort of the indoor unit 1.

[0056] Furthermore, the air guiding mechanism 20 includes an upper air guiding component 21 and a lower air guiding component 22. The upper air guiding component 21 is movably connected to the upper side wall of the air outlet 100, and the lower air guiding component 22 is movably connected to the lower edge of the air outlet 100. One of the upper air guiding component 21 and the lower air guiding component 22 can be movably arranged relative to the other. The upper air guiding component 21 and the lower air guiding component 22 have a first position where they are close to each other to form a first air duct 23, and a second position where they are far apart from each other to form a second air duct 24. A portion of the magnetic attraction component 40 is connected to the upper air guiding component 21, and another portion of the magnetic attraction component 40 is connected to the lower air guiding component 22. When the upper air guiding component 21 and the lower air guiding component 22 are in the first position, a portion of the magnetic attraction component 40 is in a clearance position.

[0057] Combination Figure 8 As shown, in the above embodiment, the air guiding mechanism 20 includes an upper air guiding component 21 and a lower air guiding component 22. The upper air guiding component 21 is movably connected to the upper sidewall of the air outlet 100, and the lower air guiding component 22 is movably connected to the lower edge of the air outlet 100. One of the upper air guiding component 21 and the lower air guiding component 22 can be movably arranged relative to the other to form different air outlet channels. The upper air guiding component 21 and the lower air guiding component 22 have a first position where they are close to each other to form a first air duct 23, and a second position where they are far apart from each other to form a second air duct 24. A portion of the magnetic attraction component 40 is connected to the upper air guiding component 21, and another portion of the magnetic attraction component 40 is connected to the lower air guiding component 22. When the upper air guide assembly 21 and the lower air guide assembly 22 are in the second position, part of the magnetic attraction assembly 40 is in the blocking position of the air outlet channel 200, and the airflow is blown out of the bottom shell 10 from the air outlet 100; when the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position, part of the magnetic attraction assembly 40 is in the avoidance position, so that part of the airflow blown from the air outlet 100 can be blown out of the bottom shell 10 through the oscillation assembly 30 in the air outlet channel 200, preventing the airflow from blowing directly.

[0058] Furthermore, the lower air guide assembly 22 includes a plate assembly 221, which includes at least one air guide plate. An oscillation assembly 30 is provided at one end of the air guide plate facing the air outlet 100. The air guide plate is rotatably connected to the lower side wall of the air outlet 100. The plate assembly 221 has a closed position for closing the air outlet 100 and an open position for opening the air outlet 100.

[0059] Combination Figures 8 to 11As shown, in the above embodiment, the lower air guide assembly 22 includes a plate assembly 221, which includes at least one air guide plate. An oscillation assembly 30 is provided at one end of the air guide plate facing the air outlet 100. The air guide plate is rotatably connected to the lower sidewall of the air outlet 100. The plate assembly 221 has a closed position for closing the air outlet 100 and an open position for opening the air outlet 100. (Combined with...) Figures 10 to 11 As shown, with the upper air guide assembly 21 and the lower air guide assembly 22 in the second position, the plate assembly 221 rotates to the open position, and part of the magnetic suction assembly 40 is located in the blocking position of the air outlet channel 200, and the airflow is blown out of the bottom shell 10 from the air outlet 100; combined with Figure 1 As shown, when the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position, the plate assembly 221 rotates to the closed position, and part of the magnetic suction assembly 40 is in the avoidance position, so that part of the airflow blown from the air outlet 100 can be blown out of the bottom shell 10 through the oscillation assembly 30 in the air outlet channel 200, which has a soft wind effect and improves the comfort of the air conditioning.

[0060] Furthermore, the plate assembly 221 includes a first air guide plate 2211 and a second air guide structure 2212. One end of the first air guide plate 2211 is rotatably connected to the lower side wall of the air outlet 100, and one end of the second air guide structure 2212 is connected to the first air guide plate 2211. An oscillation assembly 30 is provided on the surface of the upper side wall of the second air guide structure 2212 facing the air outlet 100. When the first air guide plate 2211 and the second air guide structure 2212 are in the first position, the upper air guide assembly 21 is fitted with the outer shell of the oscillation assembly 30.

[0061] Combination Figure 10 As shown, in the above embodiment, the plate assembly 221 includes a first air guide plate 2211 and a second air guide structure 2212. One end of the first air guide plate 2211 is rotatably connected to the lower sidewall of the air outlet 100, so that the first air guide plate 2211 can move to different air outlet angles according to actual needs, bringing different effects. One end of the second air guide structure 2212 is connected to the first air guide plate 2211, which facilitates the formation of an air outlet channel 200. The second air guide structure 2212 faces the air outlet 100. An oscillation component 30 is provided on the surface of the upper side wall of the 00 to bring a gentle breeze effect when the air is vented from the front. When the first air guide plate 2211 and the second air guide structure 2212 are in the first position, the upper air guide component 21 is fitted to the outer shell of the oscillation component 30 so that part of the airflow blown from the air outlet 100 can be blown out of the bottom shell 10 through the air outlet channel 200 and the oscillation component 30 provided on the surface of the second air guide structure 2212, so as to achieve a gentle breeze effect and increase the practicality of the indoor unit 1.

[0062] Furthermore, the oscillation assembly 30 includes a housing 31, which is connected to the second air guide structure 2212. Multiple third air ducts 32 are disposed within the housing 31, spaced apart along the length of the air outlet 100. At least one oscillator is disposed within each third air duct 32. Figures 2 to 4 and Figure 8 As shown, the oscillation assembly 30 includes a housing 31, which is connected to the second air guide structure 2212. In this embodiment, it is combined with... Figure 5 As shown, a plurality of third air ducts 32 are provided inside the housing 31. The plurality of third air ducts 32 are arranged at intervals along the length direction of the air outlet 100. Each third air duct 32 is provided with at least one oscillator so that part of the air blown out by the indoor unit 1 is blown out by the oscillator in the third air duct 32 to form a soft wind, preventing the airflow from blowing directly and reducing the comfort of using the indoor unit 1.

[0063] Furthermore, the magnetic suction assembly 40 includes a first magnetic suction member 41 and a second magnetic suction member 42. The first magnetic suction member 41 is connected to the upper air guide assembly 21, and the second magnetic suction member 42 is connected to the outer casing 31. The second magnetic suction member 42 is located on one side of the inlet end of each third air duct 32. One of the first magnetic suction member 41 and the second magnetic suction member 42 can be movably arranged relative to the other, so that under the action of the magnetic attraction force generated by the first magnetic suction member 41 and the second magnetic suction member 42, one of the first magnetic suction member 41 and the second magnetic suction member 42 has a blocking position and an avoidance position to block each third air duct 32.

[0064] Combination Figure 2 and Figure 3 As shown, in the above embodiment, the first magnetic suction member 41 is connected to the upper air guide assembly 21. The first magnetic suction member 41 is configured as a magnetic suction plate. The second magnetic suction member 42 is connected to the outer shell 31 and is located on one side of the inlet end of each third air duct 32. The second magnetic suction member 42 is configured as a magnetic suction sheet. One of the first magnetic suction member 41 and the second magnetic suction member 42 can be movably arranged relative to the other. When the first magnetic suction member 41 moves away from the second magnetic suction member 42, the second magnetic suction member 42 returns to the blocking position that blocks each third air duct 32 under gravity. When the first magnetic suction member 41 moves away from the second magnetic suction member 42, the first magnetic suction member 41 and the second magnetic suction member 42 generate a magnetic attraction force with each other. The second magnetic suction member 42 has a clearance position to open each third air duct 32, so that part of the air blown out by the indoor unit 1 is blown out by the oscillator in the third air duct 32 to form a soft wind.

[0065] In another embodiment, the second magnetic member 42 can also be configured as a magnetic plate, wherein the plate body part can be metal or plastic, and the plate body contains a magnet. This configuration can reduce production costs and increase the practicality of the indoor unit.

[0066] Furthermore, the first magnetic suction member 41 is fixedly connected to the upper air guide assembly 21, and the second magnetic suction member 42 is movably connected to the outer casing 31. During the process of the upper air guide assembly 21 moving the first magnetic suction member 41 to the first position, an attraction force is generated between the first magnetic suction member 41 and the second magnetic suction member 42, so that the second magnetic suction member 42 is attracted to the side where the upper air guide assembly 21 is located and moved to an avoidance position. Figure 2 As shown, in this embodiment, during the process of the upper air guide assembly 21 driving the first magnetic suction member 41 to move to the first position, the first magnetic suction member 41 and the second magnetic suction member 42 generate an adsorption force to attract the second magnetic suction member 42 toward the side where the upper air guide assembly 21 is located to the avoidance position, so that part of the air blown out by the indoor unit 1 is blown out through the oscillator in the third air duct 32 to form a soft wind.

[0067] Furthermore, the indoor unit 1 includes a panel assembly 50, which is connected to the base shell 10; wherein, the upper air guide assembly 21 has a fitting position that fits with the panel assembly 50, and the upper air guide assembly 21 can be arbitrarily stopped at a position between the first position and the fitting position.

[0068] Combination Figure 9 As shown, in the above embodiment, when the upper air guide component 21 is in the fitting position, the upper air guide component 21, the lower air guide component 22 and the bottom shell 10 form a second air duct 24. At this time, after the airflow exits from the air outlet 100, it is blown out of the bottom shell 10 through the second air duct 24, so that the airflow has a greater ability to flow along the wall, blows upward toward the ceiling, and achieves a wall-following jet along the ceiling.

[0069] Combination Figure 10 As shown in the above embodiment, when the upper air guide component 21 is arbitrarily stopped at a position between the first position and the contact position, the upper air guide component 21 and the lower air guide component 22 form an angle α, where 15°≤α≤90°. The upper air guide component 21, the lower air guide component 22 and the bottom shell 10 form a second air duct 24. At this time, after the airflow exits from the air outlet 100, it is blown out of the bottom shell 10 through the second air duct 24. At this time, the airflow outlet area is reduced and the wind speed is increased, so that air can be delivered to a longer distance after the airflow is blown out.

[0070] Furthermore, when the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position, side air channels are formed on both sides of the first air duct 23, and the air volume of the side air channels is greater than the air volume of the outlet air channel 200. Combined with... Figure 5 , Figure 6 and Figure 8As shown, in this embodiment, when the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position, part of the magnetic suction assembly 40 is in the avoidance position, and side air channels are formed on both sides of the first air duct 23. The air volume of the side air channel is greater than the air volume of the air outlet duct 200, so that a smaller portion of the airflow blown from the air outlet 100 is blown out of the bottom shell 10 through the oscillation assembly 30 in the air outlet duct 200, and a larger portion of the airflow is blown out from both sides of the indoor unit 1 through the side air channel, forming left and right airflow, preventing the airflow from blowing directly upwards, and improving the reliability of the indoor unit 1.

[0071] Furthermore, the lower air guide assembly 22 has a third position where it forms a fourth air duct 25 with the upper air guide assembly 21, and a fifth air duct 26 with the lower edge of the air outlet 100. Combined with Figure 11 As shown, in this embodiment, the lower air guide component 22 forms an angle β with the horizontal direction, wherein 5°≤β≤60°. Part of the airflow flows out through the fourth air duct 25, and part of the airflow blows out obliquely downward through the fifth air duct 26. This air outlet method can greatly improve the temperature uniformity of the room, increase the temperature drop rate, and reduce the vertical temperature difference of the room.

[0072] In another embodiment of this application, the upper air guide assembly 21, the first air guide plate 2211 and the second air guide structure 2212 are respectively connected to the bottom shell 10 through the transmission assembly 60 and driven by the power generated by the motor, so that the indoor unit 1 is in different air guide modes.

[0073] According to another embodiment of this application, a control method for an air conditioner is provided for the indoor unit 1 in the above embodiment.

[0074] Specifically, the indoor unit 1 includes: a base shell 10 having an air outlet 100; an air guide mechanism 20 rotatably disposed at the air outlet 100, at least a portion of which has an air outlet channel 200; an oscillation assembly 30 disposed within the air outlet channel 200; and a magnetic suction assembly 40 connected to the air guide mechanism 20, having a blocking position for blocking the air outlet channel 200 and a clearance position for avoiding the air outlet channel 200; wherein, when the magnetic suction assembly 40 is in the clearance position, a portion of the airflow blown from the air outlet 100 is blown out of the base shell 10 through the air outlet channel 200.

[0075] In this embodiment, the indoor unit 1 includes a bottom shell 10, an air guide mechanism 20, an oscillation component 30, and a magnetic suction component 40. The bottom shell 10 has an air outlet 100. The air guide mechanism 20 is rotatably disposed at the air outlet 100. At least a portion of the air guide mechanism 20 is provided with an air outlet channel 200. The oscillation component 30 is disposed within the air outlet channel 200. The magnetic suction component 40 is connected to the air guide mechanism 20. The magnetic suction component 40 has a blocking position for blocking the air outlet channel 200 and a yielding position for yielding to the oscillation component 30 in the air outlet channel 200. When the magnetic suction component 40 is in the yielding position, part of the airflow blown from the air outlet 100 passes through the oscillation component 30 in the air outlet channel 200 and is blown out of the bottom shell 10, thereby achieving a gentle breeze effect, solving the problem of the airflow of the indoor unit 1 blowing directly onto people, and improving the airflow comfort of the indoor unit 1.

[0076] The air guiding mechanism 20 includes an upper air guiding component 21 and a lower air guiding component 22. The upper air guiding component 21 is movably connected to the upper side wall of the air outlet 100, and the lower air guiding component 22 is movably connected to the lower edge of the air outlet 100. One of the upper air guiding component 21 and the lower air guiding component 22 can be movably arranged relative to the other to form different air outlet channels. The upper air guiding component 21 and the lower air guiding component 22 have a first position where they are close to each other to form a first air duct 23, and a second position where they are far apart to form a second air duct 24. A portion of the magnetic attraction component 40 is connected to the upper air guiding component 21, and another portion of the magnetic attraction component 40 is connected to the lower air guiding component 22. When the upper air guide assembly 21 and the lower air guide assembly 22 are in the second position, part of the magnetic attraction assembly 40 is in the blocking position of the air outlet channel 200, and the airflow is blown out of the bottom shell 10 from the air outlet 100; when the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position, part of the magnetic attraction assembly 40 is in the avoidance position, so that part of the airflow blown from the air outlet 100 can be blown out of the bottom shell 10 through the oscillation assembly 30 in the air outlet channel 200, preventing the airflow from blowing directly.

[0077] The lower air guide assembly 22 includes a plate assembly 221, which includes at least one air guide plate. An oscillation assembly 30 is provided at one end of the air guide plate facing the air outlet 100. The air guide plate is rotatably connected to the lower sidewall of the air outlet 100. The plate assembly 221 has a closed position for closing the air outlet 100 and an open position for opening the air outlet 100. Figures 10 to 11 As shown, with the upper air guide assembly 21 and the lower air guide assembly 22 in the second position, the plate assembly 221 rotates to the open position, and part of the magnetic suction assembly 40 is located in the blocking position of the air outlet channel 200, and the airflow is blown out of the bottom shell 10 from the air outlet 100; combined with Figure 1As shown, when the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position, the plate assembly 221 rotates to the closed position, and part of the magnetic suction assembly 40 is in the avoidance position, so that part of the airflow blown from the air outlet 100 can be blown out of the bottom shell 10 through the oscillation assembly 30 in the air outlet channel 200, which has a soft wind effect and improves the comfort of the air conditioning.

[0078] The panel assembly 221 includes a first air guide plate 2211 and a second air guide structure 2212. One end of the first air guide plate 2211 is rotatably connected to the lower side wall of the air outlet 100 so that the first air guide plate 2211 can move to different air outlet angles according to actual needs, bringing different effects. One end of the second air guide structure 2212 is connected to the first air guide plate 2211 to facilitate the formation of an air outlet channel 200. An oscillation component 30 is provided on the surface of the upper side wall of the second air guide structure 2212 facing the air outlet 100 so as to bring a gentle breeze effect when the air is vented from the front. When the first air guide plate 2211 and the second air guide structure 2212 are in the first position, the upper air guide component 21 and the outer shell of the oscillation component 30 are fitted together so that part of the airflow blown from the air outlet 100 can be blown out of the bottom shell 10 through the air outlet channel 200 and the oscillation component 30 provided on the surface of the second air guide structure 2212, so as to achieve a gentle breeze effect and increase the practicality of the indoor unit 1.

[0079] The first magnetic suction component 41 is connected to the upper air guide assembly 21. The first magnetic suction component 41 is configured as a magnetic suction plate. The second magnetic suction component 42 is connected to the outer casing 31 and is located on one side of the inlet end of each third air duct 32. The second magnetic suction component 42 is configured as a magnetic suction sheet. One of the first magnetic suction component 41 and the second magnetic suction component 42 can be movably arranged relative to the other. When the first magnetic suction component 41 moves away from the second magnetic suction component 42, the second magnetic suction component 42 returns to the blocking position that blocks each third air duct 32 under gravity. When the first magnetic suction component 41 moves away from the second magnetic suction component 42, the first magnetic suction component 41 and the second magnetic suction component 42 generate a magnetic attraction force with each other. The second magnetic suction component 42 has a clearance position to open each third air duct 32, so that part of the air blown out by the indoor unit 1 is blown out by the oscillator in the third air duct 32 to form a soft wind.

[0080] like Figure 12 As shown, when indoor unit 1 is in cooling mode, the indoor unit is controlled to be in automatic mode. The indoor unit has dual-outlet rapid cooling mode, ceiling-mounted wall-mounted air supply mode, long-distance air supply mode, and left and right surround gentle air supply mode. Among them, when the indoor ambient temperature T0 is greater than or equal to the first preset value T A In this case, the indoor unit is controlled in dual-outlet rapid cooling mode, and the upper air guide assembly 21 and lower air guide assembly 22 are positioned in the third position. Combined with... Figure 11 As shown, in this embodiment, T may optionally... AAt ≥28℃, the lower air guide component 22 and the upper air guide component 21 form a fourth air duct 25, and the lower air guide component 22 and the lower edge of the air outlet 100 form a fifth air duct 26. Part of the airflow flows out through the fourth air duct 25, and part of the airflow blows out obliquely downward through the fifth air duct 26. This air outlet method can greatly improve the temperature uniformity of the room, increase the temperature drop rate, and reduce the vertical temperature difference of the room.

[0081] Furthermore, when the indoor ambient temperature T0 is less than the first preset value T A In the case where the indoor ambient temperature T0 is greater than or equal to the second preset value T B In this case, the indoor unit 1 is controlled in the ceiling-mounted air supply mode, the upper air guide assembly 21 is in the attached position, and the lower air guide assembly 22 is in the second position. Combined with Figure 9 As shown, in the above embodiments, optionally, 25℃ < T B At temperatures below 28°C, the upper air guide assembly 21, the lower air guide assembly 22, and the bottom shell 10 form a second air duct 24. At this time, after the airflow exits from the air outlet 100, it is blown out of the bottom shell 10 through the second air duct 24, giving the airflow a greater ability to flow along the wall, blowing upwards toward the ceiling, and achieving a wall-following jet along the ceiling.

[0082] Furthermore, when the indoor ambient temperature T0 is less than the second preset value T B In the case where the indoor ambient temperature T0 is greater than or equal to the third preset value T C In this case, the indoor unit 1 is controlled in the long-distance air supply mode, and the upper air guide assembly 21 and the lower air guide assembly 22 are controlled in the second position. Combined with Figure 10 As shown, in this embodiment, T may optionally... C At ≤25℃, the upper air guide assembly 21, the lower air guide assembly 22 and the bottom shell 10 are arranged to form a second air duct 24. At this time, after the airflow exits from the air outlet 100, it is blown out of the bottom shell 10 through the second air duct 24. At this time, the airflow outlet area is reduced and the wind speed is increased, so that the airflow can be delivered to a longer distance after it is blown out.

[0083] Furthermore, when the indoor ambient temperature T0 is less than the third preset value T C In this case, the indoor unit 1 is controlled in a left-right wraparound gentle breeze mode, and the upper air guide assembly 21 and the lower air guide assembly 22 are in the first position. Combined with... Figure 8 As shown, in this embodiment, T may optionally... CAt ≤25℃, the upper air guide assembly 21 and the lower air guide assembly 22 are fitted together to form a first air duct 23. Side air channels are formed on both sides of the first air duct 23. The air volume of the side air channels is greater than that of the air outlet channel 200. Part of the magnetic suction assembly 40 is located in a clearance position, so that a small part of the airflow blown from the air outlet 100 is blown out of the bottom shell 10 through the oscillation assembly 30 in the air outlet channel 200. A larger part of the airflow is blown out from both sides of the indoor unit 1 through the side air channels, forming left and right airflow, preventing the airflow from blowing directly upwards, and improving the air supply comfort of the indoor unit 1.

[0084] As can be seen from the above description, the above embodiments achieve the following technical effects:

[0085] The indoor unit 1 includes a base shell 10, an air guide mechanism 20, an oscillation component 30, and a magnetic suction component 40. The base shell 10 has an air outlet 100. The air guide mechanism 20 is rotatably disposed at the air outlet 100. At least a portion of the air guide mechanism 20 is provided with an air outlet channel 200. The oscillation component 30 is disposed within the air outlet channel 200. The magnetic suction component 40 is connected to the air guide mechanism 20. The magnetic suction component 40 has a blocking position for blocking the air outlet channel 200 and a yielding position for avoiding the air outlet channel 200. When the magnetic suction component 40 is in the yielding position, part of the airflow blown from the air outlet 100 passes through the oscillation component 30 in the air outlet channel 200 and is blown out of the base shell 10, thereby achieving a gentle breeze effect, solving the problem of the airflow of the indoor unit 1 blowing directly on people, and improving the airflow comfort of the indoor unit 1.

[0086] When the indoor unit 1 is in the left-right enveloping gentle wind mode, with the upper air guide component 21 and the lower air guide component 22 in the first position, side air channels are formed on both sides of the first air duct 23. The air volume of the side air channels is greater than that of the air outlet duct 200. Some of the magnetic suction components 40 are in the avoidance position, so that a small part of the airflow blown from the air outlet 100 is blown out of the bottom shell 10 through the oscillation component 30 in the air outlet duct 200, and a larger part of the airflow is blown out from both sides of the indoor unit 1 through the side air channels, forming left and right winds, preventing the airflow from blowing directly upwards, and improving the air supply comfort of the indoor unit 1.

[0087] When the indoor unit 1 is in the long-distance air supply mode, with the upper air guide component 21 and the lower air guide component 22 in the second position, the upper air guide component 21, the lower air guide component 22 and the bottom shell 10 form a second air duct 24. At this time, after the airflow exits from the air outlet 100, it is blown out of the bottom shell 10 through the second air duct 24. At this time, the airflow outlet area is reduced and the air speed is increased, so that the airflow can be delivered to a longer distance after it is blown out.

[0088] When the indoor unit 1 is in the ceiling-mounted air supply mode, with the upper air guide component 21 in the attached position and the lower air guide component 22 in the second position, the upper air guide component 21, the lower air guide component 22 and the bottom shell 10 form a second air duct 24. At this time, after the airflow exits from the air outlet 100, it is blown out of the bottom shell 10 through the second air duct 24, so that the airflow has a greater wall-mounted flow capability, blows upward toward the ceiling, and achieves wall-mounted jet along the ceiling.

[0089] When the indoor unit 1 is in the dual-outlet rapid cooling mode, with the upper air guide component 21 and the lower air guide component 22 in the third position, the lower air guide component 22 and the upper air guide component 21 form a fourth air duct 25, and the lower air guide component 22 and the lower edge of the air outlet 100 form a fifth air duct 26. Part of the airflow flows out through the fourth air duct 25, and part of the airflow blows out obliquely downward through the fifth air duct 26. This air outlet method can greatly improve the temperature uniformity of the room, increase the temperature drop rate, and reduce the vertical temperature difference of the room.
