[0060] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than 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 efforts belong to the scope of protection of the present invention.

[0062] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0063] In addition, the meaning of "and / or" as used throughout the text is that it includes three parallel scenarios. Taking "A and / or B" as an example, it includes Scenario A, or Scenario B, or the scenario where both A and B are satisfied simultaneously.

[0064] The present invention provides an air damper assembly, a floor-standing air conditioner indoor unit, and an air conditioner.

[0065] Specifically, as Figures 1 - 5 shown, the floor-standing air conditioner indoor unit 1000 generally includes a housing 200 and an air damper assembly 100 installed in the housing 200. The housing 200 has an air outlet 210, and the air outlet 210 extends in the up and down directions. The air damper assembly 100 includes an air damper 20, and the air damper 20 is rotatably disposed in the housing 200 to open or close the air outlet 210.

[0066] Among them, the air damper assembly 100 further includes a driving mechanism for driving the air damper 20 to rotate. Specifically, the driving mechanism is installed in the housing 200, and the driving mechanism includes a mounting seat 10, and the air damper 20 is rotatably disposed in the housing 200 through the mounting seat 10.

[0067] Generally, as Figures 1 - 5 shown, the housing 200 further has an air inlet 220 and a heat exchange air duct 230 connecting the air inlet 220 and the air outlet 210.

[0068] Generally, as Figures 2 - 5 shown, the floor-standing air conditioner indoor unit 1000 further includes an indoor heat exchanger 300 disposed in the heat exchange air duct 230, and the indoor heat exchanger 300 is used to adjust the indoor air temperature, such as for refrigeration or heating.

[0069] Generally, as Figures 2 - 5 shown, the air conditioner indoor unit further includes an air impeller 400 disposed in the heat exchange air duct 230, and the air impeller 400 is used to drive the air to flow. Among them, the air impeller 400 can be selected as a cross-flow air impeller 400. Optionally, the air impeller 400 is disposed on the air outlet side of the indoor heat exchanger 300.

[0070] Generally, as Figures 2 - 5 shown, the air conditioner indoor unit further includes a wind guiding assembly 500 disposed in the heat exchange air duct 230, and the wind guiding assembly 500 is used to change the air flow direction to change the air supply direction of the floor-standing air conditioner indoor unit 1000.

[0071] In an embodiment of the present invention, as Figure 6 、 7As shown in FIGS. 9 and 10, the mounting base 10 includes a base 11 and a rotating assembly 12 rotatably provided on the base 11. One end of the air damper 20 is provided on the rotating assembly 12. A guiding and positioning structure is provided on the air damper 20 and the rotating assembly 12, and the guiding and positioning structure is used to guide the alignment of the air damper 20 and the rotating assembly 12 when the air damper 20 is installed.

[0072] It can be understood that during the assembly process of the floor-standing air conditioner indoor unit 1000, usually the driving mechanism is first installed in the housing 200, and then the air damper 20 is installed on the driving mechanism; specifically, usually the mounting base 10 is first installed in the housing 200, and then the air damper 20 is installed on the rotating assembly 12 of the mounting base 10.

[0073] For the air damper assembly 100 of the present invention, by providing a guiding and positioning structure on the air damper 20 and the rotating assembly 12, when the air damper 20 is installed, the guiding and positioning structure can guide the alignment of the air damper 20 and the rotating assembly 12, so that the air damper 20 can be accurately and quickly installed on the rotating assembly 12 and the driving mechanism, and the installation and positioning between the air damper 20 and the rotating assembly 12 are accurate, and installation inclination can be avoided; thus, problems such as abnormal noise or jamming when the air damper 20 is switched on and off caused by inaccurate installation and positioning of the air damper 20 and the driving mechanism can be avoided.

[0074] Among them, as Figure 6 、 7 shown in FIGS. 9 and 10, one part of the guiding and positioning structure is provided on the air damper 20, and the other part is provided on the rotating assembly 12. These two parts of the structure are mutually limiting structures to realize guiding the alignment of the air damper 20 and the rotating assembly 12; that is, when the air damper 20 is installed, the alignment of the air damper 20 and the rotating assembly 12 can be guided through the mutual cooperation of the above two parts of the structure.

[0075] In a specific embodiment, there are many structural forms of the guiding and positioning structure, such as a sliding fit structure of a guide groove 1211 and a guide protrusion 21, a magnetic attraction fit structure, or a sliding fit structure of a guide post and a guide hole, etc., or a combination of several different types of structures; as long as it can guide the alignment of the air damper 20 and the rotating assembly 12 when the air damper 20 is installed.

[0076] For example, in some embodiments of the present invention, the guiding and positioning structure includes a guiding post (not shown in the figure) and a guiding hole (not shown in the figure). The guiding post protrudes from the outer side surface of the guiding component (or the inner surface of the air door 20), and the guiding hole is provided on the inner surface of the air door 20 (or the outer side surface of the guiding component). The guiding post is slidably inserted into the guiding hole to guide the alignment of the air door 20 with the rotating component 12. In some embodiments, optionally, the guiding post is a conical post, and / or the guiding hole is a conical hole. Alternatively, optionally, the guiding post has a column guiding section, and this column guiding section is a conical post; and / or the guiding hole has a hole guiding section, and this hole guiding section is a conical hole.

[0077] In the following examples of the present invention, the sliding fit structure of the guiding groove 1211 and the guiding protrusion 21 is mainly taken as an example for detailed description; however, it should be noted that this is not used to limit the present invention.

[0078] Further, as Figure 6 、 7 and shown in FIG. 10, and referring to Figures 13 - 16 , the rotating component 12 includes a rotating ring 121. The rotating ring 121 is rotatably arranged on the base 11, and the guiding and positioning structure is arranged on the air door 20 and the rotating ring 121. Specifically, the rotating ring 121 is an annular member. In this way, the structure of the rotating component 12 can be simplified, and thus it is convenient for the rotating component 12 to be rotatably connected to the base 11.

[0079] Of course, in other embodiments, other rotating bodies can also be used to replace the rotating ring 121, such as a turntable, a rotating plate, a rotating block, or even a rotating box.

[0080] Further, as Figures 7 - 9 shown, the guiding and positioning structure includes a guiding protrusion 21 arranged at one end of the air door 20 and a guiding groove 1211 arranged on the outer side surface of the rotating component 12. The guiding protrusion 21 protrudes in the direction away from the other end of the air door 20, and the guiding protrusion 21 is cooperatively inserted into the guiding groove 1211.

[0081] Specifically, as Figures 7 - 9 shown, the guiding groove 1211 is arranged on the outer side surface (i.e., the outer ring surface) of the rotating ring 121.

[0082] In this way, when installing the air door 20, the alignment of the air door 20 with the rotating component 12 can be realized by inserting the guiding protrusion 21 into the guiding groove 1211.

[0083] Further, as Figures 7 - 9 shown, the guiding groove 1211 has a first notch 12111 arranged on the side of the rotating component 12 away from its rotation axis and an avoidance notch 12112 arranged on the side of the rotating component 12 away from the base 11. The first notch 12111 is communicated with the avoidance notch 12112.

[0084] In this way, when installing the air damper 20, the air damper 20 can be moved towards the direction close to the rotation axis of the rotation assembly 12, so that during the process of the guide projection 21 moving towards the direction close to the rotation axis of the rotation assembly 12, the guide projection 21 is inserted into the guide groove 1211 from the first notch 12111. Among them, the avoidance opening 12112 is used to avoid the guide projection 21, so that the guide projection 21 can be inserted into the guide groove 1211.

[0085] Specifically, in Figures 6 - 9 the shown state, the first notch 12111 is arranged forward, and the avoidance opening 12112 is arranged upward; when installing the air damper 20, the air damper 20 moves backward, and during the process of the air damper 20 moving backward, the guide projection 21 is inserted into the guide groove 1211 from the first notch 12111.

[0086] Furthermore, as Figures 7 - 9 shown, the guide groove 1211 includes a first guiding section 12113 arranged at the first notch 12111. The first guiding section 12113 extends towards the direction close to the bottom of the guide groove 1211. The first guiding section 12113 has a first guiding surface 12114 arranged obliquely. The first guiding surface 12114 is used to guide the guide projection 21 to be inserted into the guide groove 1211.

[0087] Specifically, the first guiding surface 12114 extends towards the direction close to the bottom of the guide groove 1211, so that the groove width of the first guiding section 12113 gradually decreases; when installing the air damper 20, the guide projection 21 is in sliding contact with the first guiding surface 12114 to guide the guide projection 21 to slide into the guide groove 1211. In this way, by arranging the first guiding section 12113 at the first notch 12111, it is convenient to guide the guide projection 21 to slide into the guide groove 1211, so that it is convenient to guide the air damper 20 to be aligned with the rotation assembly 12, and thus it is convenient to realize the quick positioning of the air damper 20, the rotation assembly 12 and the driving mechanism.

[0088] Specifically, the first guiding surface 12114 is arranged on the side wall of the first guiding section 12113 in the circumferential direction of the rotation assembly 12. In Figures 6 - 9 the shown state, the first guiding surface 12114 is arranged on the left side wall and / or the right side wall of the first guiding section 12113.

[0089] Optionally, there are two first guiding surfaces 12114. The two first guiding surfaces 12114 are arranged oppositely and are respectively arranged on the left side wall and the right side wall of the first guiding section 12113. In this way, it is further convenient to guide the guide projection 21 to slide (slidingly insert) into the guide groove 1211.

[0090] Specifically, the first guiding surface 12114 is an inclined surface or a curved surface.

[0091] Further, as Figures 7 - 9 shown, at least two retaining protrusions 1212 are convexly provided on the outer side surface of the rotating assembly 12, and the retaining protrusions 1212 define a guiding groove 1211. Specifically, at least two retaining protrusions 1212 are provided on the outer side surface of the rotating ring 121. In this way, the guiding groove 1211 is formed by the retaining protrusions 1212, which is beneficial to reducing the radial width of the rotating ring 121, thereby facilitating the reduction of the weight of the rotating ring 121 and the rotating assembly 12, and thus facilitating the improvement of the flexibility of the rotation of the air door 20.

[0092] Of course, in other embodiments, the outer side surface of the rotating assembly 12 may also be concavely formed to form the guiding groove 1211.

[0093] Specifically, at least two retaining protrusions 1212 are spaced apart in the circumferential direction of the rotating assembly 12; in this embodiment, at least two retaining protrusions 1212 are spaced apart in the circumferential direction of the rotating ring 121. It can be understood that, as Figures 7 - 9 shown, the guiding groove 1211 may be defined by two adjacent retaining protrusions 1212, or may be defined by two non-adjacent retaining protrusions 1212.

[0094] In a specific embodiment, the forming method and the number of the guiding grooves 1211 may be determined based on the number of the guiding protrusions 21, which will be described in detail below.

[0095] In some embodiments (not shown in the figure), the number of the guiding protrusions 21 is set to one, and the number of the guiding grooves 1211 is also correspondingly set to one. At this time, optionally, the number of the retaining protrusions 1212 is set to two, and a guiding groove 1211 is defined between the two retaining protrusions 1212. In this part of the embodiments, optionally, the guiding protrusion 21 has a certain width to ensure the stability of the connection between the air door 20 and the rotating assembly 12.

[0096] In some other embodiments (not shown in the figure), the number of the guiding protrusions 21 may be set to two. At this time, the number of the guiding grooves 1211 may be set to one or two. When the number of the guiding grooves 1211 is set to one, both guiding protrusions 21 are inserted into the guiding groove 1211, and the two guiding protrusions 21 are respectively disposed at the two side walls of the guiding groove 1211; at this time, the number of the retaining protrusions 1212 is set to two, and a guiding groove 1211 is defined between the two retaining protrusions 1212.

[0097] When the number of the guiding grooves 1211 is set to two, the two guiding protrusions 21 are respectively inserted into the two guiding grooves 1211. At this time, optionally, the number of the retaining protrusions 1212 is set to three, and a guiding groove 1211 is defined between adjacent retaining protrusions 1212; or, optionally, the number of the retaining protrusions 1212 is set to four, and a guiding groove 1211 is defined between every two retaining protrusions 1212.

[0098] Of course, as Figures 7 - 9 shown, the number of the guiding protrusions 21 can also be set to at least three, and the number of the blocking protrusions 1212 can optionally be set to at least four; based on this, optionally, the guiding groove 1211 includes a large guiding groove a formed by two outermost blocking protrusions 1212, and at least three guiding protrusions 21 are all arranged in the large guiding groove a, and the two outermost guiding protrusions 21 are respectively arranged corresponding to the two outermost blocking protrusions 1212. In this way, the connection stability between the air door 20 and the rotating assembly 12 can be ensured / increased.

[0099] Optionally, as Figure 7 and 8 shown, the guiding groove 1211 further includes a small guiding groove b formed by two blocking protrusions 1212 between the two outermost blocking protrusions 1212, and the guiding protrusions 21 between the two outermost guiding protrusions 21 are arranged in the small guiding groove b. Specifically, the number of the guiding protrusions 21 in the small guiding groove b can be one, or two or more; among them, when the number of the guiding protrusions 21 in the small guiding groove b is one, the small guiding groove b can be defined between two adjacent blocking protrusions 1212.

[0100] In this way, the guiding and positioning effects of the guiding and positioning structure can be further enhanced.

[0101] In this embodiment, as Figure 7 and 8 shown, the number of the guiding protrusions 21 is three, the four blocking protrusions 1212 are distributed in sequence, a large guiding groove a is defined between the two outermost blocking protrusions 1212, a small guiding groove b is defined between the two blocking protrusions 1212 on the inner side of (the two outermost blocking protrusions 1212), the three guiding protrusions 21 are all arranged in the large guiding groove a, the two outermost guiding protrusions 21 are respectively arranged corresponding to the two outermost blocking protrusions 1212, and the guiding protrusion 21 on the inner side of (the two outermost guiding protrusions 21) is arranged in the small guiding groove b.

[0102] Further, as Figures 7 - 9 shown, the outer end of the blocking protrusion 1212 (i.e., the end far from the outer side surface of the rotating ring 121) is bent and extended towards one side to form a first guiding section 12113 of the guiding groove 1211.

[0103] In this embodiment, as Figures 7 - 9 shown, the outer ends of the two blocking protrusions 1212 forming a guiding groove 1211 are respectively bent and extended in opposite directions to form the first guiding section 12113 of the guiding groove 1211.

[0104] In this embodiment, the lower end of the guiding protrusion 21 abuts against the upper surface of the base 11.

[0105] Further, as Figures 7 - 9As shown, the guiding projection 21 is also connected to the rotating assembly 12 through a threaded connection structure. Specifically, the guiding projection 21 is connected to the rotating ring 121 through a threaded connection structure. In this way, after the air damper 20 is aligned with the rotating ring 121, the guiding projection 21 and the rotating ring 121 can be fixedly connected together.

[0106] Specifically, as Figures 7 - 9 shown, one of the guiding projections 21 is provided with a connecting through hole 211 (which can be a threaded hole), and a threaded connection hole is correspondingly provided on the outer side surface of the rotating ring 121 (i.e., the bottom of the guide groove 1211 corresponding to this guiding projection 21). The threaded connection hole is a threaded hole, and the locking screw sequentially passes through the connecting through hole 211 and the threaded connection hole to realize the connection of the guiding projection 21 and the rotating ring 121 through the threaded connection structure.

[0107] In this embodiment, as Figures 7 - 9 shown, the threaded connection structure is arranged on the small guide groove b and the corresponding guiding projection 21.

[0108] In this way, through the above structure, the guiding alignment and positioning of one end of the air damper 20 and the outer side surface of the rotating assembly 12 can be realized.

[0109] Furthermore, as Figures 10 - 12 shown, the guiding and positioning structure further includes a clamping projection 1213 arranged on the surface of the rotating assembly 12 away from the base 11, and a clamping groove 221 arranged on the inner surface of the air damper 20. The clamping projection 1213 is clamped in the clamping groove 221. It can be understood that the clamping projection 1213 is a kind of guiding projection 21 structure, and the clamping groove 221 is also a kind of guide groove 1211 structure.

[0110] In Figures 10 - 12 the state shown, the surface of the rotating assembly 12 away from the base 11 is the upper surface of the rotating assembly 12, that is, the clamping projection 1213 is arranged on the upper surface of the rotating assembly 12.

[0111] In this embodiment, as Figures 10 - 12 shown, the clamping projection 1213 is arranged on the surface of the rotating ring 121 away from the base 11. Specifically, the clamping projection 1213 is arranged on the upper surface of the rotating ring 121.

[0112] In this way, when installing the air damper 20, the alignment of the air damper 20 and the rotating assembly 12 can be guided by inserting the clamping projection 1213 into the clamping groove 221 at the same time. Particularly, when installing the air damper 20, one end of the air damper 20 and the outer side surface of the rotating assembly 12 are guided, aligned and positioned through the cooperation of the guiding projection 21 and the guide groove 1211; the inner surface of the air damper 20 and the upper surface of the rotating assembly 12 are guided, aligned and positioned through the cooperation of the clamping projection 1213 and the clamping groove 221.

[0113] Furthermore, as Figures 10 - 12As shown, a clamping protrusion 22 is provided on the inner surface of the air damper 20 (i.e., the surface of the air damper 20 facing the rotation axis of the air damper 20), and the clamping groove 221 is provided on the clamping protrusion 22. In this way, it is convenient to keep the connection position between the clamping protrusion 1213 and the clamping groove 221 away from the inner surface of the air damper 20, so as to increase the connection stability between the air damper 20 and the rotating assembly 12.

[0114] Specifically, as Figures 10 - 12 shown, the clamping groove 221 has a second notch 2211 provided towards the inner side of the air damper 20 (i.e., the side of the air damper 20 facing the rotation axis of the air damper 20), and an avoidance notch (not shown in the figure) provided towards the base 11, and the second notch 2211 is communicated with the avoidance notch. In this way, when installing the air damper 20, the air damper 20 can be moved towards the direction close to the rotation axis of the rotating assembly 12, so that during the movement of the clamping protrusion 1213, the clamping protrusion 1213 is inserted into the clamping groove 221 from the second notch 2211. Among them, the avoidance notch is used to avoid the clamping protrusion 1213 so that the clamping protrusion 1213 can be inserted into the clamping groove 221. In Figures 10 - 12 the state shown, the second notch 2211 faces forward and the avoidance notch faces downward.

[0115] Specifically, as Figures 10 - 12 shown, the clamping groove 221 penetrates the clamping protrusion 22 in the thickness direction of the clamping protrusion 22, so as to facilitate the cooperation between the clamping protrusion 1213 and the clamping groove 221.

[0116] Furthermore, as Figures 10 - 12 shown, a forming groove 222 is provided on the outer side surface of the clamping protrusion 22. Oppositely arranged two limiting protrusions 223 are provided at the bottom of the forming groove 222. A clamping groove 221 is formed between the two limiting protrusions 223. At least one of the limiting protrusions 223 is spaced from the side wall of the forming groove 222 adjacent to the limiting protrusion 223.

[0117] In this way, it can be ensured that at least one of the limiting protrusions 223 can move elastically, so that the width of the clamping groove 221 can be adjusted. Thus, it is convenient to guide the clamping protrusion 1213 into the clamping groove 221, and it is also convenient to limit the clamping protrusion 1213 after the clamping protrusion 1213 is clamped in the clamping groove 221.

[0118] In this embodiment, as Figures 10 - 12 shown, both of the two limiting protrusions 223 are spaced from the respective corresponding side walls of the forming groove 222 to further facilitate guiding the clamping protrusion 1213 into the clamping groove 221.

[0119] Of course, in other embodiments, the card slot 221 can also be formed in other structural forms. For example, in one embodiment, a forming groove 222 is provided on the outer side surface of the clamping convex portion 22. A limiting convex portion 223 is provided at the bottom of the forming groove 222. The limiting convex portion 223 is arranged between two opposite side walls of the forming groove 222. A card slot 221 is formed between the limiting convex portion 223 and one side wall of the forming groove 222, and the limiting convex portion 223 is spaced from the other side wall of the forming groove 222. In this way, the limiting convex portion 223 can also be elastically movable, so that the width of the card slot 221 can be adjusted, which is convenient for guiding the clamping convex 1213 into the card slot 221 and also for limiting the clamping convex 1213 after the clamping convex 1213 is clamped in the card slot 221.

[0120] Further, as Figures 10 - 12 shown, the card slot 221 includes a second guiding section 2212 provided at the second notch 2211. The second guiding section 2212 extends in a direction close to the bottom of the card slot 221. The second guiding section 2212 has an inclined second guiding surface 2213 for guiding the clamping convex portion 22 to be clamped into the card slot 221.

[0121] Specifically, as Figures 10 - 12 shown, the second guiding surface 2213 extends in a direction close to the bottom of the card slot 221, so that the slot width of the second guiding section 2212 gradually decreases. When installing the air door 20, the clamping convex 1213 is in sliding contact with the second guiding surface 2213 to guide the clamping convex 1213 to slide into the card slot 221. In this way, by providing the second guiding section 2212 at the second notch 2211, it is convenient to guide the clamping convex 1213 to slide into the card slot 221, which is convenient for guiding the air door 20 to be aligned with the rotating assembly 12, and thus convenient for quickly positioning the air door 20 with the rotating assembly 12 and the driving mechanism.

[0122] Specifically, the second guiding surface 2213 is provided on the side wall of the second guiding section 2212. In the Figures 10 - 12 shown state, the second guiding surface 2213 is provided on the left side wall and / or the right side wall of the second guiding section 2212.

[0123] Optionally, as Figures 10 - 12 shown, there are two second guiding surfaces 2213. The two second guiding surfaces 2213 are arranged oppositely and are respectively provided on the left side wall and the right side wall of the second guiding section 2212. In this way, it is further convenient to guide the clamping convex 1213 to slide (slidingly insert) into the card slot 221.

[0124] Specifically, the second guiding surface 2213 is an inclined surface or a curved surface.

[0125] Further, as Figures 10 - 12As shown, the outer end of the limiting convex part 223 (i.e., the end far from the inner surface of the air damper 20) is bent and extended to one side (i.e., to the side far from the other limiting convex part 223) to form the second guiding section 2212 of the clamping groove 221.

[0126] In this embodiment, as Figures 10 - 12 shown, the outer ends of the two limiting convex parts 223 are respectively bent and extended in opposite directions to form the second guiding section 2212 of the clamping groove 221. Specifically, the side wall surface of the forming groove 222 is provided with an inclined avoiding surface corresponding to the second guiding section 2212 of the clamping groove 221 for avoiding the corresponding limiting convex part 223.

[0127] Furthermore, as Figures 10 - 12 shown, the clamping groove 221 further includes a clamping section 2115 arranged near the bottom of the clamping groove 221. The clamping convex 1213 is arranged in the clamping section 2115. An anti - detachment section 2114 is arranged between the clamping section 2115 and the second guiding section 2212. The anti - detachment section 2114 includes an anti - detachment convex part (not shown in the figure) arranged on the side wall of the clamping groove 221 to prevent the clamping convex 1213 from detaching from the clamping section 2115. In this way, the clamping convex 1213 can be limited in the clamping section 2115, so that the mutual limitation between the clamping convex 1213 and the clamping groove 221 can be realized, and then the air damper 20 and the rotating ring 121 can be limited, and further the air damper 20 can be stably installed on the rotating ring 121.

[0128] Furthermore, as Figures 10 - 12 shown, at least two pairs of the clamping grooves 221 and the clamping convexes 1213 are provided. In this way, the guiding and positioning effects of the guiding and positioning structure can be further enhanced, and then the connection stability between the air damper 20 and the rotating assembly 12 can be further ensured / increased.

[0129] Optionally, the clamping convex 1213 is a convex block protruding from the upper surface of the rotating ring 121.

[0130] Furthermore, as Figures 13 - 16 shown, the rotating assembly 12 further includes a sealing ring 122. The sealing ring 122 is arranged on the side of the rotating ring 121 far from the base 11. The sealing ring 122 has an installation notch 1221, and the air damper 20 is arranged at the installation notch 1221. In Figure 13 and 14 the state shown, the sealing ring 122 is installed on the upper side of the rotating ring 121.

[0131] During operation, the rotating ring 121 can drive the air damper 20 and the sealing ring 122 to rotate together.

[0132] Thus, by arranging the sealing ring 122 on the upper side of the swivel ring 121, it is convenient to hide the swivel ring 121; meanwhile, the sealing function for the swivel ring 121 can be realized to prevent the humidifying water from splashing out. At the same time, by arranging the installation notch 1221 on the sealing ring 122, it can be used to avoid the air door 20 and its installation structure, and can also enhance the overall flatness of the air door assembly 100.

[0133] Further, as Figures 13 - 16 shown, the air door assembly 100 further includes a driving assembly 30, and the driving assembly 30 is installed on the base 11 of the mounting seat 10, and the driving assembly 30 is used to drive the swivel ring 121 to rotate.

[0134] Specifically, as Figures 13 - 16 shown, the driving assembly 30 includes a driving motor 31 and a transmission assembly, and the driving motor 31 drives the swivel ring 121 to drive the air door 20 to rotate through the transmission assembly. The driving motor 31 is installed on the base 11.

[0135] In this embodiment, the transmission assembly includes a transmission gear 32 connected to the output end of the driving motor 31, and the inner side surface (i.e., the inner ring surface) of the swivel ring 121 is provided with meshing teeth meshingly connected to the transmission gear 32.

[0136] Further, as Figure 6 and 10 shown, there are two mounting seats 10, and the two mounting seats 10 are respectively arranged at both ends of the air door 20. Thus, both ends of the air door 20 can be rotatably installed on the housing 200 through the two mounting seats 10, thereby improving the rotational stability of the air door 20 during rotation. Specifically, in Figure 6 or the state shown in 10, one mounting seat 10 is arranged at the upper end of the air door 20, and the other mounting seat 10 is arranged at the lower end of the air door 20.

[0137] Further, as Figure 10 and 16 shown, the rotating assembly 12 further includes a sealing cover (not labeled in the figure), the sealing ring 122 is arranged on the surface of the base 11 facing the swivel ring 121 (i.e., the upper surface in Figure 10 or the state shown in 16), and the sealing cover is arranged inside the swivel ring 121 and the sealing ring 122 to cover the transmission gear 32 and the like.

[0138] Further, as Figures 3 - 5As shown, the housing 200 further has a door closing area provided at the air outlet 210 and a door opening area provided in the heat exchange air duct 230. The door closing area corresponds to the air outlet 210. The air door 20 closes the air outlet 210 in the door closing area, and the air door 20 opens the air outlet 210 in the door opening area. Specifically, when the air door 20 rotates to the door closing area, it can close the air outlet 210, and when the air door 20 rotates to the door opening area, it can open the air outlet 210.

[0139] Specifically, when the air door 20 rotates to the door opening area, the air door 20 can be used for air guiding. Specifically, when the air door 20 rotates to the door opening area, the air door 20 can be used to form a part of the air duct wall of the heat exchange air duct 230.

[0140] Furthermore, as Figures 3 - 5 shown, the air guiding assembly 500 is provided in the heat exchange air duct 230. The air guiding assembly 500 has a blowing state extending out of the door closing area and an avoidance state located inside the door closing area (i.e., on the side of the door closing area facing the rotation axis of the air door 20) to avoid the air door 20.

[0141] Specifically, as Figure 3 shown, and referring to Figure 20 and 21 , when the air conditioner is shut down or performs other operations (such as self-sterilization, etc.), it is necessary to rotate the air door 20 to the door closing area to close the air outlet 210; at this time, the air guiding assembly 500 can be adjusted to the avoidance state so that the air guiding assembly 500 is provided inside the door closing area to avoid the air door 20, so that the air door 20 can rotate to the door closing area to close the air outlet 210.

[0142] As Figure 4 and 5 shown, and referring to Figure 18 and 19 , when the air conditioner is working, the air door 20 rotates from the door closing area to the door opening area to open the air outlet 210. At this time, the air guiding assembly 500 can be adjusted from the avoidance state to the blowing state so that the air guiding assembly 500 extends out of the door closing area. In this way, the volume of the air guiding assembly 500 exposed at the air outlet 210 can be increased, so as to facilitate increasing the air blowing range of the air guiding assembly 500.

[0143] In the present invention, by making the air guiding assembly 500 have a blowing state extending out of the door closing area, the volume of the air guiding assembly 500 exposed at the air outlet 210 can be increased, so as to facilitate increasing the air blowing range of the air guiding assembly 500. At the same time, by making the air guiding assembly 500 have an avoidance state located inside the door closing area, the air door 20 can be avoided, so that the air door 20 can rotate to the door closing area to close the air outlet 210.

[0144] In a specific embodiment, by designing the structure of the air guiding component 500 itself and / or the installation method of the air guiding component 500, it can have a blowing state and an avoidance state. The following will be described in detail with reference to the structure of the air guiding component 500 in an embodiment.

[0145] Further, as Figures 17 - 23 shown, and with particular reference to Figure 23 , the air guiding component 500 includes an air guiding member 510 and louvers 520. The air guiding member 510 has an air guiding channel 5102 and an air guiding cavity 5101 with an opening. The air guiding channel 5102 communicates with the air guiding cavity 5101, and the louvers 520 are rotatably installed in the air guiding cavity 5101.

[0146] Among them, as Figure 22 shown, etc., the air guiding member 510 extends in the up-down direction, and a plurality of louvers 520 are spaced apart in the up-down direction; in this way, the air guiding component 500 can be rotated to blow air in the left-right direction by rotating the air guiding member 510 left and right, and the air guiding component 500 can be rotated to blow air in the up-down direction by swinging the louvers 520 up and down.

[0147] It can be understood that by controlling the orientation of the opening of the air guiding member 510, the flowing air can flow into the air guiding cavity 5101 from the opening of the air guiding member 510 and be sent out from the air guiding channel 5102 (as Figure 5 shown), or the flowing air can flow into the air guiding cavity 5101 from the air guiding channel 5102 and be sent out from the opening of the air guiding member 510 (as Figure 4 shown).

[0148] It can be understood that it can be made such that: all of the louvers 520 are arranged in the air guiding cavity 5101; or it can also be made such that the louvers 520 are arranged in the air guiding cavity 5101, but the louvers 520 can extend out of the air guiding cavity 5101 from the opening of the air guiding member 510 by rotating the louvers 520.

[0149] Further, as Figures 3 - 5 shown, the air guiding component 500 is rotatably arranged in the heat exchange air duct 230. In this way, it can have a blowing state and an avoidance state.

[0150] Specifically, as Figure 5 shown, the air guiding component 500 has a first rotation angle range in which the air guiding component 500 rotates to extend out of the door closing area, and the blowing state includes a first blowing state of the air guiding component 500 in the first rotation angle range.

[0151] It can be understood that for the first rotation angle range: assuming that a certain point on the air guiding assembly 500 is used as the rotation starting point at a certain position, then when the air guiding assembly 500 rotates out of the door closing area from just starting to rotate and extends until it rotates away (i.e., the air guiding assembly 500 is located inside the door closing area), the rotation angle range of this point on the air guiding assembly 500 is the first rotation angle range; in this embodiment, the opening of the air guiding member facing the air outlet and the opening of the air guiding member facing inwards or outwards can be used as the rotation starting point. The above is equally applicable to the second rotation angle range in the following text, and will not be elaborated further below.

[0152] In this way, when the air guiding assembly 500 rotates to the first rotation angle range, the air guiding assembly 500 can extend out of the door closing area, thereby increasing the volume of the air guiding assembly 500 exposed at the air outlet 210. Then, when the air guiding assembly 500 rotates within the first rotation angle range, the air guiding assembly 500 can be in the first air supply state, and the air supply range of the air guiding assembly 500 in the left - right direction can be increased.

[0153] In this embodiment, when the air guiding assembly 500 is within the first rotation angle range, the opening of the air guiding cavity 5101 faces inwards (roughly referring to the direction from the surface of the housing 200 towards the center inside the housing 200, and outwards is the opposite), so that the air guiding member 510 extends out of the door closing area, thereby increasing the rotation range of the air guiding channel 5102, and thus increasing the air supply range of the air guiding assembly 500 in the left - right direction.

[0154] At this time, the louver 520 is located inside the air guiding member 510, and the up - down air supply can be realized by controlling the rotation of the louver 520.

[0155] Specifically, as Figure 3 shown, the air guiding assembly 500 has a second rotation angle range in which the air guiding assembly 500 is in an avoidance state when rotated.

[0156] In this embodiment, as Figure 3 shown, when the air guiding assembly 500 is within the second rotation angle range, the opening of the air guiding cavity 5101 faces outwards, and the louver 520 rotates to the outside of the air guiding member 510.

[0157] In a specific embodiment, the air guiding assembly 500 can be in an avoidance state solely by the rotation of the air guiding assembly 500, or the air guiding assembly 500 can be in an avoidance state by the rotation of the air guiding assembly 500 in combination with the structural design of the air guiding assembly 500 itself.

[0158] Specifically, when all the louvers 520 are disposed within the air guiding cavity 5101, the louvers 520 cannot extend out of the air guiding cavity 5101 by rotation. Then, the rotation of the louvers 520 will not affect the setting of the avoidance state of the air guiding assembly 500. That is, the air guiding assembly 500 can be made to be in the avoidance state solely by the rotation of the air guiding assembly 500. Specifically, the rotation axis of the air guiding assembly 500 can be offset towards the opening of the air guiding member 510, so that the air guiding assembly 500 has a blowing state extending out of the door closing area and an avoidance state located inside the door closing area to avoid the air door 20.

[0159] When the louvers 520 can extend out of the air guiding cavity 5101 by rotation, the rotation of the louvers 520 will affect the setting of the avoidance state of the air guiding assembly 500. At this time, there are two handling methods: First, by setting the position of the rotation axis of the air guiding assembly 500 (controlling the offset distance of the rotation axis of the air guiding assembly 500 towards the side of the air guiding member 510), when the air guiding assembly 500 is within the second rotation angle range, the rotation of the louvers 520 will not interfere with the air door 20; Second, by setting the position of the rotation axis of the air guiding assembly 500, when the air guiding assembly 500 is within the second rotation angle range, the louvers 520 can avoid the air door 20 by adjusting the rotation angle of the louvers 520, so that the air guiding assembly 500 has an avoidance state. In this embodiment, the second method is adopted to set the air guiding assembly 500, and the following is a detailed description.

[0160] In this embodiment, as Figure 3 shown, and referring to Figure 20 and 21 , when the air guiding assembly 500 is within the second rotation angle range, the louvers 520 have an avoidance angle (range) of rotating to avoid the air door 20, so as to avoid interference between the louvers 520 and the air door 20, so that the air guiding assembly 500 is in an avoidance state, thereby enabling the air door 20 to rotate to the door closing area.

[0161] Further, as Figure 4 shown, and referring to Figure 18 and 19 , the blowing state further includes a second blowing state in which the louvers 520 rotate to extend out of the door closing area when the air guiding assembly 500 is within the second rotation angle range.

[0162] Specifically, when the air guiding assembly 500 is within the second rotation angle range, the louvers 520 have a blowing angle (range) of rotating to extend out of the door closing area. In this way, by making the louvers 520 rotate to extend out of the door closing area, the sweeping range of the louvers 520 in the up and down directions can be increased, and thus the blowing / sweeping range of the air guiding assembly 500 and the floor-standing air conditioner indoor unit 1000 in the up and down directions can be increased.

[0163] Further, as Figures 23 - 26As shown in the figure, in the cross-section of the air guiding member 510 (a cross-section perpendicular to the up-down direction), the air guiding member 510 has a first cross-section line c located at the opening of the air guiding cavity 5101 and a second cross-section line d disposed opposite to the first cross-section line c. The axial distance between the rotation axis of the air guiding member 510 and the first cross-section line c is less than the axial distance between the rotation axis of the air guiding member 510 and the second cross-section line d.

[0164] In this way, it is convenient to realize that when the air guiding assembly 500 rotates to the first rotation angle range, the air guiding member 510 extends out of the door closing area, and when the air guiding assembly 500 rotates to the first rotation angle range, the air guiding assembly 500 is adjusted to the avoidance state.

[0165] Specifically, as Figures 24 - 26 shown, the axial distance between the rotation axis of the air guiding member 510 and the first cross-section line c is the first axial distance D, and the axial distance between the rotation axis of the air guiding member 510 and the second cross-section line d is the second axial distance d; the ratio of the first axial distance D to the second axial distance d is greater than or equal to 0.2 and less than or equal to 0.7.

[0166] It can be understood that if the ratio of the first axial distance D to the second axial distance d is too small, it will cause too much of the air guiding member 510 to extend out of the door closing area, and the rotation space required for the air guiding assembly 500 to rotate is too large, so that the gap between the air guiding assembly 500 and the air outlet 210 is too large, which is not conducive to the air guiding assembly 500 to send air. If the ratio of the first axial distance D to the second axial distance d is too large, it is not conducive to realizing large-range air supply. Therefore, optionally, the ratio of the first axial distance D to the second axial distance d is greater than or equal to 0.2 and less than or equal to 0.7; more specifically, the ratio of the first axial distance D to the second axial distance d is greater than or equal to 0.4 and less than or equal to 0.6; optionally, the ratio of the first axial distance D to the second axial distance d is equal to 0.5.

[0167] Regarding the first axial distance, the following is described in the following cases:

[0168] 1) As Figure 24 shown, in the first embodiment of the air guiding member 510, the first cross-section line c is an arc convex in the direction away from the second cross-section line d, and the first axial distance is: the distance between the farthest point on the first cross-section line c from the rotation axis of the air guiding member 510 and the rotation axis of the air guiding member 510.

[0169] 2) As Figure 25 shown, in the second embodiment of the air guiding member 510, the first cross-section line c is an arc concave in the direction close to the second cross-section line d, and the first axial distance is: the distance between the connection line of the two end points of the first cross-section line c and the rotation axis of the air guiding member 510.

[0170] 3) As Figure 26As shown, in the third embodiment of the air deflector 510, the first cross-sectional line c is a straight line. Then, the first axial distance is the distance between the rotation axis of the air deflector 510 and the first cross-sectional line c.

[0171] Specifically, the second cross-sectional line d can be a straight line or an arc; for the second axial distance, it can be defined by referring to the way of the first axial distance.

[0172] In this embodiment, through the above structural settings, the left and right air guiding angle range of the air guiding assembly 500 can reach 145 degrees, and the air supply angle increases by 65%, with obvious effects.

[0173] Furthermore, as Figure 23 shown, the air deflector 510 includes an air guiding part 5105 disposed opposite to the opening of the air guiding cavity 5101, and the air guiding channel 5102 is provided in the air guiding part 5105.

[0174] When the air guiding assembly 500 is within the first rotation angle range, the air guiding part 5105 extends out of the door closing area; when the air guiding assembly 500 is within the second rotation angle range, the air guiding part 5105 rotates to the inner side of the louver 520.

[0175] In this way, it is convenient for left and right air supply.

[0176] Specifically, as Figures 23 - 26 shown, the air guiding part 5105 includes a plurality of air guiding strips 5103 spaced apart in the circumferential direction of the air deflector 510, and an air guiding channel 5102 is formed between two adjacent air guiding strips 5103. In this way, an air guiding grille structure can be formed.

[0177] Of course, the air guiding channel 5102 can also be set in other structural forms. For example, the air guiding channel 5102 is set as a plurality of air guiding micro-holes formed on the air guiding part 5105 to achieve draft-free air supply.

[0178] Furthermore, as Figures 23 - 26 shown, the air deflector 510 further includes two support parts 5104 disposed on both sides of the air guiding part 5105, and the louver 520 is rotatably disposed on the support parts 5104. In this way, by providing the support parts 5104, on the one hand, it is used to enclose the air guiding cavity 5101 with the air guiding part 5105, and on the other hand, it can be used to install the louver 520.

[0179] Optionally, the air deflector 510 is an air guiding frame.

[0180] Specifically, as Figures 23 - 26As shown, the air guiding part 5105 has an arc-shaped structure. In this way, on the one hand, it is convenient to increase the air supply range of the air guiding part 5105; on the other hand, it is also convenient to reduce the rotation space required for the rotation of the air guiding component 500. Of course, the air guiding part 5105 can also be set to be flat.

[0181] It should be noted that, as Figures 23 - 26 shown, when the air guiding part 5105 has an arc-shaped structure, in the cross-section of the air guiding member 510, the second section line d is an arc; when the air guiding part 5105 is flat, in the cross-section of the air guiding member 510, the second section line d is a straight line.

[0182] Furthermore, as Figures 17 - 20 shown, the air guiding component 500 is rotatably mounted on the base 11 of the mounting seat 10. Specifically, both ends of the air guiding member 510 are respectively rotatably mounted on the base 11.

[0183] Specifically, the air guiding component 500 further includes a first power component provided on the base 11 for driving the air guiding member 510 to rotate. Optionally, the first power component includes a first motor, and the first motor is mounted on the base 11 and drives the air guiding member 510 to rotate (through a transmission structure).

[0184] Specifically, as Figures 17 - 20 shown, the air guiding component 500 further includes a driving connecting rod 540, and the driving connecting rod 540 is rotatably connected to a plurality of louvers 520 for driving the louvers 520 to rotate.

[0185] Specifically, the air guiding component 500 further includes a second power component provided on the base 11, and the second power component drives the louvers 520 to rotate / swing through the driving connecting rod 540. Optionally, the second power component includes a second motor, and the second motor is mounted on the base 11 and is connected to the driving connecting rod 540.

[0186] It should be noted that the air guiding component 500 can also be formed by other structures. For example, in one example, the air guiding component 500 includes an air guiding cylinder and louvers 520 rotatably arranged in the air guiding cylinder. The air guiding cylinder is rotatably arranged in the heat exchange air duct 230. The air guiding cylinder includes a plurality of air guiding strips 5103 sequentially and spaced apart in the circumferential direction of the air guiding cylinder, or a plurality of ventilation micropores are arranged on the side wall of the air guiding cylinder; the rotation axis of the air guiding cylinder is offset toward one side of the air guiding cylinder, so that the air guiding component 500 has a blowing state extending out of the door closing area and an avoidance state located inside the door closing area to avoid the air door 20.

[0187] Of course, in other embodiments of the present invention, the air guiding component 500 can also have a blowing state and an avoidance state through other structural settings.

[0188] For example, in another embodiment of the present invention, the air guiding assembly 500 is movably disposed in the heat exchange air duct 230 (front and back); the air guiding assembly 500 has a first position where the air guiding assembly 500 moves to extend out of the door closing area, so that the air guiding assembly 500 is in the air supply state; the air guiding assembly 500 further has a second position where the air guiding assembly 500 moves to be located inside the door closing area, so that the air guiding assembly 500 is in the avoiding state. In this embodiment, specifically, the air guiding assembly 500 is slidably disposed in the heat exchange air duct 230 (front and back), so that the air guiding assembly 500 is movably disposed in the heat exchange air duct 230 (front and back).

[0189] In this embodiment, the structure of the air guiding assembly 500 may be the same as or substantially the same as the structure of the air guiding assembly 500 in the previous embodiment, that is: the air guiding assembly 500 includes an air guiding member 510 and louvers 520, the air guiding member 510 has an air guiding channel 5102 and an air guiding cavity 5101 with an opening, the air guiding channel 5102 is communicated with the air guiding cavity 5101, and the louvers 520 are rotatably installed in the air guiding cavity 5101. Specifically, the opening of the air guiding cavity 5101 faces inward. Alternatively, the air guiding assembly 500 includes an air guiding cylinder and louvers 520 rotatably disposed in the air guiding cylinder, and the air guiding cylinder is movably disposed in the heat exchange air duct 230 (front and back).

[0190] The present invention also provides an air conditioner, which includes an air conditioner outdoor unit (not shown in the figure) and a floor-standing air conditioner indoor unit, and the floor-standing air conditioner indoor unit is connected to the air conditioner outdoor unit through a refrigerant pipe. For the specific structure of the floor-standing air conditioner indoor unit, refer to the above embodiments. Since the air conditioner of the present invention adopts all the technical solutions of the above all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated herein one by one.

[0191] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are all included in the patent protection scope of the present invention.
