[0036] Figure 1 is a schematic cross-sectional view of an air conditioner according to an embodiment of the present application, and is described in conjunction with Figures 2-5The present application provides an air conditioner, which comprises an indoor unit 5, an air outlet pipe 8 and a terminal device 1. The indoor unit 5 comprises an air outlet, and the air outlet pipe 8 is connected to the air outlet. The terminal device 1 comprises a reel 15 and an air outlet curtain 12. The reel 15 is rotatably arranged. The air outlet curtain 12 is wound on the reel 15. The air outlet curtain 12 has a communication air channel 13 inside, and at least one surface of the air outlet curtain 12 is provided with one or more air outlet holes 14. The air outlet holes 14 are connected to the air outlet pipe 8 through the communication air channel 13.

[0037] Figures 1-3 In the embodiment, the positions of the indoor unit 5, the outdoor unit 7, the refrigerant pipeline and the air outlet pipe 8 are only schematic, and the indoor unit 5 is not necessarily arranged on the air outlet curtain 12 or the upper side of the ceiling. The indoor unit 5 can be arranged at any position in the room. The outdoor unit 7 is not necessarily arranged on the roof, and the outdoor unit 7 can be arranged at any position in the outdoor.

[0038] In the embodiment, at least one surface of the air outlet curtain 12 is provided with one or more air outlet holes 14, and the air outlet holes 14 are connected to the air outlet pipe 8 through the communication air channel 13 inside the air outlet curtain 12. The air outlet pipe 8 is connected to the air outlet of the indoor unit 5. The air conditioner can be a wind-cooled air conditioner, or a water-cooled air conditioner, or other forms of split air conditioner. In the embodiment, the indoor unit 5 is arranged in the room and is provided with a heat exchanger. The heat exchanger of the indoor unit 5 is connected to the heat exchanger of the outdoor unit 7 through the refrigerant pipeline to transfer cold or heat. In the embodiment, the indoor unit 5 is not provided with an air outlet panel, and the air outlet pipe 8 is connected to the air outlet of the indoor unit 5. The temperature-adjusted air flow generated by the indoor unit 5 enters the air outlet curtain 12 of the terminal device 1 through the air outlet pipe 8 and is blown out through the air outlet holes 14. Of course, the indoor unit 5 can also generate fresh air flow, and the fresh air flow enters the air outlet curtain 12 of the terminal device 1 through the air outlet pipe 8 and is blown out through the air outlet holes 14. The indoor unit 5 can be provided with a fan, and the temperature-adjusted air flow or the fresh air flow is transported to the terminal device 1 under the action of the fan. Alternatively, the fan can also be arranged in the air outlet pipe 8, and the fan extracts the air flow in the indoor unit 5 and transports the air flow to the terminal device 1.

[0039] In the embodiment, the length of the air outlet pipe 8 is not limited. The air outlet pipe 8 can be one or multiple. The reel 15 can be horizontally arranged, and when rotating, the air outlet curtain 12 can be unfolded downward under the action of gravity, or the air outlet curtain 12 can be unfolded upward under the action of tension. The reel 15 can also be vertically arranged, and when rotating, the air outlet curtain 12 can be unfolded leftward or rightward. Of course, the reel 15 can also be obliquely arranged, so that the air outlet curtain 12 is unfolded obliquely. The reel 15 can be provided with or connected to a driving device to realize forward rotation and reverse rotation under the action of the driving device.

[0040] The air outlet curtain 12 is fixedly connected to the winding shaft 15, has a certain width and an unfolding length, and the width and the unfolding length are both much larger than the thickness. When the winding shaft 15 rotates, the other end of the air outlet curtain 12 is unfolded or wound relative to the winding shaft 15. The air outlet curtain 12 can be made of flexible material as a whole to be wound on the winding shaft 15. The air outlet curtain 12 can also be made of hard material combined with flexible material, for example, a structure similar to a bamboo curtain. The air outlet curtain 12 can also be made of hard material as a whole, for example, a structure similar to a chain. Generally, the air outlet curtain 12 is in a rectangular shape, but can also be in other shapes, for example, a wave shape, an oval shape, etc. The shape can be set according to the home decoration style, which is not limited here.

[0041] In use, by rotating the winding shaft 15, the air outlet curtain 12 can have two states of unfolding and winding. In the unfolding state, the temperature adjusting airflow or fresh air airflow can be blown out from the air outlet hole 14 to adjust the temperature or ventilate the room. In the winding state, the air outlet curtain 12 is wound on the winding shaft 15, and does not occupy the limited space in the room. Therefore, the limited space in the room is reasonably utilized, and the effect of improving the appearance of the room is improved.

[0042] In some embodiments of the air conditioner of the present application, the air outlet hole 14 is a plurality of air outlet holes 14, and the plurality of air outlet holes 14 are densely arranged on one surface of the air outlet curtain 12 according to a preset rule.

[0043] In some embodiments of the air conditioner of the present application, as shown in Figures 1-5 the air outlet hole 14 is a plurality of air outlet holes 14, and the plurality of air outlet holes 14 are densely arranged on one surface of the air outlet curtain 12 according to a preset rule.

[0044] In this embodiment, the air outlet hole 14 is a plurality of air outlet holes 14, and the communication passage 13 can be one, and all the air outlet holes 14 are connected to the communication passage 13. The communication passage 13 can also be a plurality of communication passages 13, and all the air outlet holes 14 are distributed into the plurality of communication passages 13. The plurality of air outlet holes 14 are densely arranged on the lower surface of the air outlet curtain 12, that is, the positions of the air outlet holes 14 are arranged according to the shape and size of the air outlet curtain 12. When the area of the lower surface of the air outlet curtain 12 is large, the number of the air outlet holes 14 is large, and the air outlet range is wide. It should be noted that when the air outlet curtain 12 is not completely unfolded, that is, the unfolding degree is 0%-100%, only the air outlet holes 14 in the region in the unfolded state can blow air outward. The air outlet holes 14 in the region in the winding state are blocked when winding. That is, the number and position of the air outlet holes 14 can change with the unfolding and winding of the air outlet curtain 12, that is, the air outlet area and the air outlet range can change. In this way, the air outlet curtain 12 can be unfolded to a preset area according to the need, so as to change the air outlet area of the air conditioner, enrich the temperature adjusting mode, and further improve the user experience.

[0045] In particular, when the air outlets 14 are arranged uniformly along the unrolling direction of the air curtain 12, the number of air outlets 14 that can blow air outward is proportional to the unrolling area or unrolling degree, that is, the air outlet area and the air outlet range are proportional to the unrolling area or unrolling degree.

[0046] In the embodiment, the preset rule can be set according to factors such as temperature adjustment requirements and aesthetic requirements. The air outlets 14 can be arranged uniformly and simply, or arranged according to a certain specific pattern, for example, arranged according to a multiple circular ring, a multiple rectangle, a multiple five-pointed star, a central radiation, and the like.

[0047] In particular, a decorative pattern can also be arranged on the outer surface of the air curtain 12, and the shape and position of the air outlets 14 can be arranged according to the preset rule to match the decorative pattern. For example, the decorative pattern is a starry sky pattern, the air outlets 14 are arranged at the stars in the pattern, and the shape of the air outlets 14 is the shape of the stars. In this way, the air conditioner and the home decoration style can be further unified, a hidden and traceless installation effect can be achieved, and the aesthetic appearance of the home decoration can be improved.

[0048] In some embodiments of the air conditioner of the present application, as shown in Figures 4-5 the thickness of the air curtain 12 is less than 3 cm. In the embodiment, the thickness of the air curtain 12 is the maximum thickness. The reel 15 is arranged horizontally, and when the air curtain 12 is unrolled downward, in order to make the air volume of the air outlets 14 located at the upper and lower parts of the air curtain 12 consistent after the air curtain 12 is unrolled, the thickness of the air curtain 12 is usually arranged to gradually decrease from top to bottom, and the cross-sectional area of the communication air duct 13 at the upper part of the air curtain 12 is greater than that at the lower part. Of course, the thickness of the air curtain 12 can also be arranged to be consistent from top to bottom, so as to have a better appearance when unrolled.

[0049] On the other hand, the greater the thickness of the air curtain 12, the larger the cross section of the communication air duct 1312 inside the air curtain 12 can be arranged, so as to increase the air volume without increasing the air outlet speed. However, the increase in thickness also increases the space occupation when unrolled and rolled up. The thickness of the air curtain 12 is less than 3 cm, which can minimize the space occupation of the terminal device 1.

[0050] In some embodiments of the air conditioner of the present application, as shown in Figure 1 , Figure 3 the air outlet 14 is a long slot extending along the width direction of the air curtain 12, and a plurality of air outlets 14 are uniformly and spacedly arranged along the unrolling direction of the air curtain 12. On the one hand, the air curtain 12 can blow air more uniformly, and on the other hand, the total area of the air outlets 14 that blow air is proportional to the unrolling area or unrolling degree of the air curtain 12, which is convenient for accurately adjusting the air outlet area or air volume.

[0051] In some embodiments of the air conditioner of the present application, as shown in Figure 2As shown, the air outlet holes 14 are round holes or special-shaped holes. The round holes can improve the uniform air outlet effect of the air outlet curtain 12. The special-shaped holes can be polygonal holes, irregular holes, etc.

[0052] In particular, the outer surface of the air outlet curtain 12 is provided with decorative patterns, and the decorative patterns have corresponding patterns, such as stars, moons, flowers, birds, insects, etc. The positions of the special-shaped holes are at the corresponding patterns, and the shapes of the special-shaped holes are consistent with the corresponding patterns. In this way, the unity of the air conditioner and the home decoration style can be further achieved, the hidden and traceless installation effect can be achieved, and the home decoration aesthetics can be improved.

[0053] In some embodiments of the air conditioner of the present application, as shown in Figures 1-5 The reel 15 is arranged to rotate on the top wall or a wall in the room.

[0054] In this embodiment, the reel 15 can be arranged to rotate on the top wall. When the reel 15 rotates, the air outlet curtain 12 can be unfolded downward under the action of gravity, and the air outlet holes 14 on one or both surfaces of the air outlet curtain 12 can outlet air outward. The reel 15 can be arranged to rotate on a wall. When the reel 15 is arranged in parallel with the wall, the air outlet curtain 12 can be unfolded in parallel along the wall, and the air outlet holes 14 on the surface of the air outlet curtain 12 facing the room can outlet air outward. In particular, decorative patterns can be arranged on the air outlet curtain 12. At this time, the terminal device 1 can be used as a home decoration, and the air outlet curtain 12 can be used as a wallboard or wallpaper. In this way, the unity of the air conditioner and the home decoration style can be further achieved, the hidden and traceless installation effect can be achieved, and the home decoration aesthetics can be improved.

[0055] When the air conditioner is not used, the reel 15 is rotated to wind the air outlet curtain 12 on the reel 15 on the top wall or the wall, thereby releasing the limited indoor space.

[0056] In some embodiments of the air conditioner of the present application, as shown in Figures 4-5 The reel 15 is arranged to rotate on the top of a wall in the room, and the air outlet curtain 12 is parallel to the wall.

[0057] In this embodiment, when the reel 15 rotates, the air outlet curtain 12 can be unfolded downward under the action of gravity and in parallel along the wall. This installation method can minimize the occupation of the limited indoor space when the air outlet curtain 12 is unfolded. In particular, decorative patterns can be arranged on the air outlet curtain 12. At this time, the terminal device 1 can be used as a home decoration, and the air outlet curtain 12 can be used as a wallboard or wallpaper. In this way, the unity of the air conditioner and the home decoration style can be further achieved, the hidden and traceless installation effect can be achieved, and the home decoration aesthetics can be improved.

[0058] On the other hand, the air outlet curtain 12 is provided with air outlet holes 14 on the side surface facing the indoor space. When air is blown out of the air outlet holes 14, the air outlet curtain 12 will swing backward under the action of the air flow. In the present embodiment, the wall behind the air outlet curtain 12 can support the air outlet curtain 12 to avoid or reduce the backward swing of the air outlet curtain 12. Of course, the end device 1 can also solve the problem of backward swing through other ways, such as providing an unfolding guide rail, or providing a counterweight at the lower end of the air outlet curtain 12, and the like, which will not be described here.

[0059] In some embodiments of the air conditioner of the present application, as shown in Figures 1-5 When the air outlet curtain 12 is fully unfolded, the height H of the air outlet curtain 12 is greater than one half of the height of the wall where it is located. The greater the height H of the air outlet curtain 12 when it is fully unfolded, the greater the air outlet area and the greater the air outlet range, which can achieve large-area and multi-angle air outlet. On the other hand, the greater the height H of the air outlet curtain 12 when it is fully unfolded, the greater its volume when it is in the rolled-up state, which will occupy more indoor space. In actual use, the specific height of the air outlet curtain 12 when it is fully unfolded needs to be set by considering various factors.

[0060] When the air conditioner is working, the cold air flow will sink downward and the hot air flow will float upward, which will cause the indoor temperature to be stratified or uneven. In the prior art, because the air outlet panel is too small or the height range of the air outlet panel is too small, to solve the problem of indoor temperature stratification or unevenness caused by cold air and hot air, it is usually only possible to proceed from the air outlet speed and direction, that is, to increase the air outlet speed and to make the cold air blow obliquely upward and the hot air blow obliquely downward. Although this technical solution can solve the problem of indoor temperature stratification to some extent, because the air outlet speed is relatively large, it is easy to cause discomfort to the user when the cold air or hot air directly blows on the user, and the user experience is poor. In the present embodiment, because the height of the air outlet curtain 12 after being unfolded is greater than one half of the height of the wall where it is located, the range of the air outlet holes 14 on the air outlet curtain 12 along the upper and lower distribution is relatively large. When the air conditioner is cooling, part or all of the hot air flow is blown out from the lower end of the air outlet curtain 12, even if the speed is relatively slow when it is blown out, it can also float upward after being blown out while flowing forward. When the air conditioner is heating, part or all of the hot air flow is blown out from the upper end of the air outlet curtain 12, even if the speed is relatively slow when it is blown out, it can also sink downward after being blown out while flowing forward. In this way, while avoiding or reducing the problem of strong wind directly blowing on the user, the problem of indoor temperature stratification or unevenness is solved.

[0061] In some embodiments of the air conditioner of the present application, when the air outlet curtain 12 is fully unfolded, the height of the air outlet curtain 12 is equal to the height of the wall where it is located. In the present embodiment, the air outlet curtain 12 is unfolded to the same height as the wall where it is located, which further increases the air outlet area and the air outlet range, and while avoiding or reducing the problem of strong wind directly blowing on the user, it can further improve the uniformity of the indoor temperature distribution and avoid indoor temperature stratification.

[0062] In some embodiments of the air conditioner of the present application, as shown in Figures 1-3 the width W of the air outlet curtain 12 is greater than one third of the width of the wall on which it is located.

[0063] The greater the width of the air outlet curtain 12, the greater the air outlet area and the air outlet range, which will bring better air outlet effect. On the other hand, since the indoor wall is usually provided with a door, a window or a storage furniture near the wall, etc., when the width of the air outlet curtain 12 is too large, it is easy to interfere with the door, the window or the storage furniture. Therefore, in actual use, the width of the air outlet curtain 12 needs to be set comprehensively considering various factors.

[0064] In some embodiments of the air conditioner of the present application, as shown in Figures 1-3 one air outlet curtain 12 can be correspondingly provided with one winding shaft 15, or multiple air outlet curtains 12 can be correspondingly provided with one winding shaft 15, and the multiple air outlet curtains 12 are wound side by side along the width direction on one winding shaft 15. The width and the height when unfolded of the multiple air outlet curtains 12 can be the same or different. For example, the length of the winding shaft 15 is the width of two air outlet curtains 12, and the two air outlet curtains 12 can be wound side by side along the width direction on one winding shaft 15. In actual use, when the air outlet curtain 12 is unfolded, all the air outlet curtains 12 can be selected to be unfolded at the same time, or some of the air outlet curtains 12 can be selected to be unfolded, and the remaining air outlet curtains 12 remain to be wound. Of course, some of the air outlet curtains 12 can also be selected to be unfolded in sequence.

[0065] In some embodiments of the air conditioner of the present application, as shown in Figures 4-5 the air outlet curtain 12 comprises a front wall 121 and a rear wall 122. The front wall 121 and the rear wall 122 form a cavity therebetween, and the cavity is the communication air duct 13.

[0066] In this embodiment, the front wall 121 and the rear wall 122 can be two wall surfaces which are fixedly connected or integrally formed. The front wall 121 and the rear wall 122 can also be one wall surface with a certain thickness, and the inside of the wall surface has a cavity. It should be noted that the cavity can be one or multiple. The multiple cavities can be connected with each other or isolated from each other. In actual application, the cavities can be set according to the shape and position of the air outlet hole 14 and the specific structure of the air outlet pipe 8.

[0067] In some embodiments of the air conditioner of the present application, the air outlet curtain 12 further comprises multiple conduits clamped between the front wall 121 and the rear wall 122, and the multiple conduits are the communication air duct 13. In this embodiment, the multiple conduits can be connected with each other or isolated from each other.

[0068] In some embodiments of the air conditioner of the present application, the air outlet hole 14 is connected with the air outlet pipe 8 through the communication air duct 13 and the winding shaft 15. The winding shaft 15 is internally provided with a hollow connection air duct which connects the communication air duct 13 and the air outlet pipe 8. In some embodiments of the air conditioner of the present application, as shown in

[0069] Since the reel 15 is rotatably arranged, the reel 15 will rotate relative to the air outlet pipe 8, and at the same time, the air outlet curtain 12 at the connection with the reel 15 will also rotate relative to the air outlet pipe 8. When the communication air channel 13 is directly connected with the air outlet pipe 8, an additional rotatable docking mechanism needs to be arranged. In the embodiment, a hollow connection air channel is arranged inside the reel 15, which can be arranged at the shaft center of the reel 15. The air outlet pipe 8 is coaxially arranged with the connection air channel, so that when the reel 15 rotates, the connection air channel can rotate coaxially with the air outlet pipe 8. The connection air channel does not rotate relative to the air outlet curtain 12, and the connection air channel can be directly fixedly connected with the communication air channel 13 inside the air outlet curtain 12.

[0070] In some embodiments of the air conditioner of the present application, as shown in Figures 1-3 Fig. 1, the terminal device 1 is one or more. When the terminal device 1 is more than one, the plurality of terminal devices 1 are arranged in the same room or in different rooms. The plurality of terminal devices 1 are connected with the air outlet of the indoor unit 5 through one or more air outlet pipes 8. For example, the terminal device 1 is two, and the two reels 15 of the two terminal devices 1 can be arranged on two opposite walls in one room, or the two reels 15 of the two terminal devices 1 can be arranged in two rooms.

[0071] In some embodiments of the air conditioner of the present application, the indoor unit 5 and the terminal device 1 are arranged at a distance, and the indoor unit 5 and the terminal device 1 are in the same room or in different rooms.

[0072] In the embodiment, the indoor unit 5 can be connected with one terminal device 1 through one air outlet pipe 8, or can be connected with a plurality of terminal devices 1 through one or more air outlet pipes 8, so as to provide temperature-adjusted air flow or fresh air flow for a plurality of air outlet curtains 12. The plurality of terminal devices 1 can be in the same room or in different rooms. In some embodiments of the air conditioner of the present application, the indoor unit 5 is arranged in a room close to the outdoor unit 7. In this way, the refrigerant pipeline between the indoor unit 5 and the outdoor unit 7 can be shortened. In other embodiments of the air conditioner of the present application, the indoor unit 5 is arranged at an optimal position, at which the distance between the indoor unit 5 and the terminal device 1 and the distance between the indoor unit 5 and the outdoor unit 7 are optimized in size and ratio. The efficiency of the refrigerant pipeline and the air outlet pipe 8 in transferring cold or heat is the highest at the position. On the other hand, since the cost of the refrigerant pipeline is greater than the cost of the air outlet pipe 8, in actual use, the efficiency and cost can be comprehensively considered to determine the specific position of the indoor unit 5.

[0073] In particular, the indoor unit 5 can also be placed at a position far from the user, so that the noise generated by the operation of the indoor unit 5 can be reduced, and the user experience can be improved.

[0074] In some embodiments of the air conditioner of the present application, as shown inFigures 1-3 As shown, the air conditioner further comprises a return air duct 6, one end of which is connected to the return air inlet of the indoor unit 5, and the other end of which is located in the room where the terminal device 1 is located.

[0075] In this embodiment, the inlet of the return air duct 6 can be located near the roof, wall or floor of the room. The return air duct 6 can have one or more inlets. For example, the return air duct 6 has two inlets with opening and closing functions, one of which is located at a higher position of the wall and the other of which is located at a lower position of the wall. When the air conditioner is in cooling mode, the inlet at the higher position is opened and the inlet at the lower position is closed to draw the relatively hot air, which is cooled by the indoor unit 5 and then blown out by the air outlet curtain 12. When the air conditioner is in heating mode, the air outlet curtain 12 blows out air, the inlet at the lower position is opened and the inlet at the higher position is closed to draw the relatively cold air, which is heated by the indoor unit 5 and then blown out by the air outlet curtain 12.

[0076] It should be appreciated by those skilled in the art that, although the present application has been fully described and illustrated by a number of exemplary embodiments, many other variations or modifications can be determined or deduced directly from the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and construed as covering all such other variations or modifications.
