[0002] The indoor units of air conditioners currently on the market usually have a rotatable air outlet frame at their air outlets, and a swingable air guide member inside the air outlet frame. The air outlet frame drives the air guide member to rotate to change the air supply angle. However, such indoor units of air conditioners usually install a drive assembly for driving the air guide member to swing on the inner side of the air outlet frame, and the motor wire of the drive assembly must pass out of the air outlet frame to connect to the power supply or the electric control board. During the rotation of the air outlet frame, the drive assembly rotates with the air outlet frame, which easily causes the motor wire to rotate and entangle, and thus easily causes damage to the motor wire.

[0036] The purpose, features and advantages of the present invention will be further described with reference to the accompanying drawings in conjunction with the embodiments. DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0040] See also Figures 1 to 3In one embodiment of the air conditioner indoor unit, the air conditioner indoor unit 100 includes a housing 110, an air outlet frame 210, an air guide member (such as an air guide plate 220 or a shutter 230), a driving assembly 240 and a transmission member 250 (such as Figure 3 and Figure 4 The housing 110 is provided with an air inlet 101 and an air outlet 102 connected to the air inlet 101. The air outlet frame 210 has a rotation axis (such as Figure 3 As shown in FIG. 1 , the air outlet frame 210 is rotatably mounted in the housing 110 around the rotation axis and corresponds to the air outlet 102. The air guide is swingably mounted in the air outlet frame 210. The driving assembly 240 is mounted in the housing 110 and is located outside the air outlet frame 210. One end of the transmission member 250 is connected to the driving assembly 240, and the other end of the transmission member 250 is inserted into the air outlet frame 210 to connect with the air guide. The transmission member 250 can be driven by the driving assembly 240 to move up and down, thereby driving the air guide to swing.

[0041] Specifically, the cross section of the housing 110 cut by a plane perpendicular to the up-down direction may be circular, square or other irregular shapes. Specifically, the rear end of the cross section is semicircular, and the front end thereof gradually narrows forward and is semi-elliptical, so that the cross section is roughly egg-shaped. This can reduce the overall volume of the air conditioner indoor unit 100, reduce the space occupied by its front end, and make the whole unit miniaturized.

[0042] The housing 110 also has an air supply duct 141 connecting the air inlet 101 and the air outlet 102. The air outlet 102 is provided with a damper 150, which can be rotated to the inner wall of the air supply duct 141 to open the air outlet 102, and can be rotated to the air outlet 102 to close the air outlet 102. The housing 110 includes a chassis 111, a front shell 112, a rear shell 113 and a face frame 114. The chassis 111, the front shell 112 and the rear shell 113 are surrounded to form a cavity, the face frame 114 is installed in the cavity, and the front shell 112 is fixed to the face frame 114. The wind wheel assembly 130, the heat exchange assembly 120 and the air duct assembly 140 for forming the air supply duct 141 of the air conditioner indoor unit 100 are all installed in the cavity.

[0043] When the air conditioner indoor unit 100 is working, the wind wheel assembly 130 drives air from the air inlet 101 into the air supply duct 141 of the housing 110, and after heat exchange by the heat exchange assembly 120, the air is blown from the air supply duct 141 to the air outlet frame 210, and then the air is guided into the room by the air guide in the air outlet frame 210. In this process, the air outlet frame 210 plays the role of converging and squeezing the airflow, thereby helping to guide a large amount of airflow to the air supply area required by the user.

[0044] In view of the fact that the air outlet 102 of the housing 110 is in the shape of a long strip and extends in the vertical direction, the air outlet frame 210 is also arranged in the shape of a long strip to correspond to the air outlet 102. Correspondingly, the rotation axis of the air outlet frame 210 also extends in the vertical direction. The rotation axis of the air outlet frame 210 is a virtual axis, which is used to describe the rotation center of the air outlet frame 210, that is, the air outlet frame 210 can rotate around the rotation axis. By driving the air outlet frame 210 to rotate, the air supply direction of the air outlet frame 210 can also be adjusted, such as supplying air to the left, to the right, or to the front. In addition, by arranging a swingable air guide in the air outlet frame 210, the air guide can be swung to assist the air guide frame in directing the airflow to the air supply area required by the user. As for the swing direction of the air guide, the air guide can be swung in the vertical direction (such as the shutter 230) or in the left and right direction (such as the air guide plate 220).

[0045] The technical solution of the present invention is to install the driving assembly 240 in the housing 110 and arrange the driving assembly 240 on the outside of the air outlet frame 210, the driving assembly 240 is connected to one end of the transmission member 250, and the other end of the transmission member 250 is inserted into the air outlet frame 210 and connected to the air guide member, so that the driving assembly 240 can drive the transmission member 250 to move up and down, and then drive the air guide member to swing through the movement of the transmission member 250. Since the driving assembly 240 is located on the outside of the air outlet frame 210, when the air outlet frame 210 rotates, the driving assembly 240 does not rotate with the air outlet frame 210, so that the motor wire of the driving assembly 240 will not be entangled, and the motor wire winding damage can be avoided.

[0046] To facilitate understanding of the air outlet frame 210 , the air outlet frame 210 is first introduced and described below.

[0047] See also Figure 2 and Figure 3 In one embodiment, the air outlet frame 210 has a first vent 201 and a second vent 202 located on opposite sides of the rotation axis, and the first vent 201 and the second vent 202 are connected. The air guide member of the air outlet frame 210 can be set corresponding to the first vent 201, and can also be set corresponding to the second vent 202. When the air conditioner indoor unit 100 is working, the air outlet frame 210 is driven to rotate 180°, so that the positions of the first vent 201 and the second vent 202 of the air outlet frame 210 can be swapped, thereby realizing the switching of the air outlet 102 of the air outlet frame 210 and changing the air supply mode. Wherein:

[0048] When the air outlet frame 210 rotates so that the first vent 201 faces inward and the second vent 202 faces outward, the air flow blown out from the air supply duct 141 of the air-conditioning indoor unit 100 first enters the air outlet frame 210 through the first vent 201, then flows to the second vent 202 after being guided by the air guide, and finally blows from the second vent 202 to the air outlet 102.

[0049] When the air outlet frame 210 rotates so that the second vent 202 faces inward and the first vent 201 faces outward, the air flow blown out from the air supply duct 141 of the air-conditioning indoor unit 100 first enters the air outlet frame 210 through the second vent 202, then flows toward the first vent 201 after being guided by the air guide, and finally blows from the first vent 201 toward the air outlet 102.

[0050] See also Figure 2 and Figure 6 In one embodiment, the air outlet frame 210 includes a frame 211 and two side panels 212 installed on opposite sides of the frame 211, and an air outlet cavity connecting the first vent 201 and the second vent 202 is defined between the two side panels 212. In other words, the air outlet frame 210 includes three parts, the frame 211 and the two side panels 212, and the first vent 201 and the second vent 202 are formed on the frame 211. After the frame 211 and the two side panels 212 are manufactured and formed, the two side panels 212 are respectively installed on the left and right sides of the frame 211, so as to be assembled with the frame 211 to form the air outlet frame 210. Among them, the air outlet cavity of the air outlet frame 210 is defined between the two side panels 212.

[0051] Of course, in other embodiments, the air outlet frame 210 may also include a first frame and a second frame (not shown), the first frame and the second frame are correspondingly assembled along the thickness direction of the air outlet frame 210, wherein the first frame is formed with a first vent 201, and the second frame is formed with a second vent 202. In other words, the air outlet frame 210 includes a first frame and a second frame, and after the first frame and the second frame are manufactured and formed respectively, the first frame and the second frame are correspondingly assembled together along the front-back direction to form the air outlet frame 210. The first frame and the second frame are connected to form an air outlet cavity of the air outlet frame 210.

[0052] See also Figures 4 to 6 In one embodiment, to facilitate the installation of the air outlet frame 210, the air conditioner indoor unit 100 further includes a first mounting seat 160 and a second mounting seat 170 respectively disposed at both ends of the air outlet frame 210, and the two ends of the air outlet frame 210 are respectively rotatably connected to the first mounting seat 160 and the second mounting seat 170. Specifically, a rotating shaft 203 extending along the rotating axis is protruded at both ends of the air outlet frame 210, and the two rotating shafts 203 are respectively rotatably connected to the first mounting seat 160 and the second mounting seat 170.

[0053] Since the first mounting seat 160 and the second mounting seat 170 are both located outside the air outlet frame 210, the driving assembly 240 can be mounted on the first mounting seat 160, so there is no need to add an additional structure for mounting the driving assembly 240. Optionally, a mounting box 161 for mounting the driving assembly 240 is provided on the first mounting seat 160. The mounting box 161 can be integrally formed with the first mounting seat 160; or, the mounting box 161 is a separately formed component and is mounted on the first mounting seat 160 after being formed.

[0054] It is taken into consideration here that since the driving component 240 needs to be connected to one end of the transmission member 250, during the up and down movement of the transmission member 250, the moving path of the transmission member 250 may be offset, such as tilted movement, which will cause the transmission member 250 to interfere with and collide with other nearby components, which is not conducive to driving the air guide member to swing stably.

[0055] See also Figures 3 to 6 Therefore, in this embodiment, in order to avoid this situation, a limiting guide groove 162 extending in the vertical direction and opening downward is formed in the installation box 161, and the transmission member 250 is partially accommodated in the limiting guide groove 162 and can move along the limiting guide groove 162. When the transmission member 250 moves in the vertical direction, the transmission member 250 is limited to move in the limiting guide groove 162, so that the transmission member 250 can be prevented from deflecting during the movement, ensuring the stability of its movement, and thus not easily interfering with other nearby components.

[0056] It is also considered that since the transmission member 250 passes through the air outlet frame 210, when the air outlet frame 210 rotates, the air outlet frame 210 may interfere with the transmission member 250. Therefore, in order to avoid interference between the two, it is defined that the extension direction of the transmission member 250 and the rotation axis are in the same straight line direction. In other words, the transmission member 250 and the rotation axis are coaxially arranged, so that no matter how the air outlet frame 210 rotates, the air outlet frame 210 always rotates relative to the transmission member 250, so as not to interfere with the transmission member 250.

[0057] As described above, the end of the air outlet frame 210 is provided with a rotating shaft 203 extending along the rotating axis. Therefore, the rotating shaft 203 can be hollowed out to allow the transmission member 250 to pass through, thereby achieving coaxial arrangement of the rotating member and the rotating axis.

[0058] The air conditioner indoor unit 100 further includes a driving motor 270, which is connected to the air outlet frame 210 to drive the air outlet frame 210 to rotate around the rotation axis. Since the driving assembly 240 and the transmission member 250 are both installed on the first mounting seat 160, in order to avoid interference between the driving motor 270 and the two, the driving motor 270 is installed on the second mounting seat 170.

[0059] Based on any of the above embodiments, there may be a variety of design methods for the structural type of the driving assembly 240, which are not limited here, such as but not limited to: a motor and chain combination structure; or a motor and gear combination structure; or a motor and a slider, push rod combination structure, etc.

[0060] See also Figure 6 and Figure 7 In one embodiment, the driving assembly 240 includes a motor 241 and a driving gear 242 connected to the motor shaft of the motor 241; the transmission member 250 is provided with a first tooth 251 meshing with the driving gear 242, and the first tooth 251 is used to mesh with the driving gear 242. The structure of the combination of the motor 241 and the driving gear 242 is relatively simple and easy to assemble.

[0061] Specifically, the transmission member 250 is arranged in a cylindrical shape, which can reduce the space occupied by the transmission member 250 and avoid interference with the rotating shaft 203. The transmission member 250 is provided with a first tooth 251 at the upper part, and the first tooth 251 has a plurality of first tooth grooves for the active gear 242 to mesh with. The first tooth grooves are arranged in an annular shape, and such a design can enable the transmission rod to obtain a larger transmission ratio. Therefore, compared with a conventional rack, when the active gear 242 rotates a unit angle, the transmission member 250 can obtain a larger displacement.

[0062] Based on any of the above embodiments, for different types of air guide members (such as louvers 230 and air guide plates 220 ), the manner in which the driving assembly 240 is connected to the air guide member through the transmission member 250 is different.

[0063] See also Figures 6 to 8 In one embodiment, the air guide member is an air guide plate 220 that is long and extends in the vertical direction. The air conditioner indoor unit 100 further includes a reversing assembly 260, which connects the air guide plate 220 and a portion of the transmission member 250 located in the air outlet frame 210. When the transmission member 250 moves in the vertical direction, the air guide plate 220 is driven to swing in the horizontal direction (equivalent to swinging in the left and right direction) through the reversing assembly 260. That is, the transmission member 250 is connected to the air guide plate 220 through the reversing assembly 260.

[0064] When the driving component 240 drives the transmission member 250 to move up and down, the transmission member 250 drives the reversing component 260 to move, and the reversing component 260 drives the air guide plate 220 to swing left and right during this movement, thereby converting the up and down movement potential energy of the transmission member 250 into the lateral swinging potential energy of the air guide plate 220.

[0065] See also Figures 6 to 8 Furthermore, in order to facilitate the installation of the reversing assembly 260, a receiving cavity 213 is formed at the end of the air outlet frame 210, and the receiving cavity 213 is used for installing the reversing assembly 260. The receiving cavity 213 can be integrally formed with the air outlet frame 210; or, the receiving cavity 213 is a separately formed component and is installed on the air outlet frame 210 after being formed.

[0066] There are also many types of specific structures for the reversing assembly 260. In one embodiment, the reversing assembly 260 includes a first transmission shaft 261, a second transmission shaft 263, a first bevel gear 262, a second bevel gear 264 and a driven gear 265. The first transmission shaft 261 extends in the up-down direction, and a portion of the first transmission shaft 261 passes through the accommodating cavity 213 and is connected to the rotating shaft 221 of the air guide plate 220; the first bevel gear 262 is provided on the first transmission shaft 261 and is located at the portion of the first transmission shaft 261 located in the accommodating cavity 213; the second transmission shaft 263 extends in the lateral direction, and the second transmission shaft 263 is rotatably installed in the accommodating cavity 213; the second bevel gear 264 is provided on one end of the second transmission shaft 263 and meshes with the first bevel gear 262; the driven gear 265 is provided on the second transmission shaft 263 and meshes with the second meshing teeth 252 formed on the transmission member 250.

[0067] The first bevel gear 262 and the second bevel gear 264 are both bevel gears, which are used to transmit motion and power between two intersecting axes (specifically the first transmission shaft 261 and the second rotating shaft 263). The specific structure of the bevel gear is relatively common in the mechanical field and will not be described in detail here. The above can be understood as that the first bevel gear 262 and the first transmission shaft 261 are coaxially arranged and move together; the second bevel gear 264 is coaxially arranged and move together with the driven gear 265 and the second transmission shaft 263. When the driving assembly 240 drives the transmission member 250 to move up and down, the transmission member 250 drives the driven gear 265 to rotate through the second meshing teeth 252, and the driven gear 265 drives the second bevel gear 264 to rotate in the same direction through the second transmission shaft 263, and then the second bevel gear 264 drives the first bevel gear 262 to rotate, and the first bevel gear 262 drives the air guide plate 220 to swing horizontally through the first transmission shaft 261.

[0068] See also Figures 7 to 9Further, in order to increase the transmission ratio between the transmission member 250 and the driven gear 265, the second gear 252 has a plurality of second tooth grooves for the driven gear 265 to mesh with, and the second tooth grooves are arranged in an annular shape. For details, please refer to the introduction of the first gear 251, which will not be repeated here.

[0069] See also Figures 8 to 10 In one embodiment, in order to ensure the stability of the connection between the first transmission shaft 261 and the air guide plate 220, optionally, the first transmission shaft 261 has a transmission shaft arm 2611 and a connecting shaft arm 2612 connected to the transmission shaft arm 2611, and the radial cross-section of the connecting shaft arm 2612 is polygonal, and the connecting shaft arm 2612 is used to connect with the rotating shaft 214 of the air guide member.

[0070] Specifically, the radial cross section of the connecting shaft arm 2612 can be triangular, quadrilateral, pentagonal, or hexagonal, etc., so that the connecting shaft arm 2612 has multiple sides, and a corner is formed between any two adjacent sides. Correspondingly, the rotating shaft 221 of the air guide plate 220 is provided with an axial hole for matching with the connecting shaft arm 2612, so that it can be matched and plugged with the connecting shaft arm 2612. When the two are plugged and assembled and fixed, the connecting shaft arm 2612 is not easy to slide relatively in the axial hole, thereby smoothly driving the air guide plate 220 to swing.

[0071] Furthermore, if the first bevel gear 262 is close to the bottom wall of the accommodating chamber 213, the contact surface between the first bevel gear 262 and the bottom wall of the accommodating chamber 213 is large, the friction resistance is large, and the second bevel gear 264 has a greater difficulty in driving the first bevel gear 262 to rotate. To improve this situation, a sleeve 214 is convexly provided on the bottom wall of the accommodating chamber 213, and the sleeve 214 is used for the connecting shaft arm 2612 to pass through to connect with the rotating shaft 221 of the air guide plate 220. The first bevel gear 262 can be separated from the bottom wall of the accommodating chamber 213 by the sleeve 214, so that the difficulty of the second bevel gear 264 driving the first bevel gear 262 to rotate can be reduced.

[0072] However, if the first bevel gear 262 contacts the top of the sleeve 214, friction resistance will also be generated on the contact surface between the first bevel gear 262 and the sleeve 214. Therefore, in order to further reduce the difficulty of the second bevel gear 264 driving the first bevel gear 262 to rotate, a limiting convex ring 2613 may be convexly provided on the circumference of the connecting shaft arm 2612, and the limiting convex ring 2613 is used to abut against the top of the sleeve 214, and the limiting convex ring 2613 is spaced apart from the first bevel gear 262. Therefore, after the assembly is completed, the first bevel gear 262 is only connected to the first transmission shaft 261, which is equivalent to being suspended and has no contact with the storage box, thereby greatly reducing the difficulty of the second bevel gear 264 driving the first bevel gear 262 to rotate.

[0073] See also Figure 6 In one embodiment, the type of the air guide member is different from the above-mentioned air guide plate 220. In this embodiment, the air guide member is a sheet-shaped louver 230, and when the transmission member 250 moves in the up-down direction, it drives the louver 230 to swing in the up-down direction. Specifically, a plurality of louvers 230 are arranged at intervals in the up-down direction, and the plurality of louvers 230 are connected by a connecting rod. The lower end of the transmission member 250 is connected to the connecting rod. When the driving assembly 240 drives the transmission member 250 to move up and down, the transmission member 250 drives the connecting rod to move up and down, thereby driving the plurality of louvers 230 to swing up and down.

[0074] The present invention also provides an air conditioner, the air conditioner comprising an air conditioner outdoor unit and an air conditioner indoor unit 100, the air conditioner indoor unit 100 being connected to the air conditioner outdoor unit via a refrigerant pipe.
