[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0035] 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.

[0036] 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.

[0037] The present invention provides an air-conditioning indoor unit, which can be a floor-standing air-conditioning indoor unit or a vertically-mounted air-conditioning indoor unit, etc. The present invention is described by taking a floor-standing air-conditioning indoor unit as an example, but the present invention is not limited thereto.

[0038] In the embodiment of the present invention, Figures 1 to 6 As shown, the air conditioner indoor unit includes: a shell 10, having a panel 11, the shell 10 is provided with a first air duct 12, and the panel 11 is provided with a first air outlet 13 connected to the first air duct 12; a drainage module 20, including a drainage cover 21, the drainage cover 21 can be installed on the first air outlet 13 so as to be movable forward and backward, and is connected to the first air duct 12 to guide the airflow in the first air duct 12; the radial dimension of the drainage cover 21 gradually increases toward the air outlet direction, and when the drainage cover 21 moves forward from the first air outlet 13, a flow expansion gap 22 is formed between the outer wall surface of the drainage cover 21 and the edge of the first air outlet 13.

[0039] In this embodiment, the shell 10 extends in the vertical direction as a whole, and the horizontal cross-sectional shape of the shell 10 can be circular, elliptical, rectangular, etc., which can be selected according to actual use requirements and is not specifically limited here. The panel 11 extends in the vertical direction. It can be understood that the panel 11 is located at the front side of the shell 10, and the opening direction of the first air outlet 13 is to open forward. The number of the first air outlet 13 can be multiple and arranged at intervals along the length direction of the panel 11. The shape of the first air outlet 13 can be circular or elliptical. The shell 10 also has an air inlet, and the first air duct 12 connects the air inlet and the first air outlet 13. The drainage module 20 is used for the air flow to pass through and diffuse the air flow passing through it, that is, the air flow changes its original flow direction after passing through the drainage module 20 and can flow in different directions, thereby realizing the diffuse flow of the air outlet, and realizing the air outlet with a breeze or no wind. The two ends of the drainage cover 21 are open and the radial size gradually increases along the air outlet direction, that is, the drainage cover 21 is arranged in a cone shape with an outward expansion. The inner end opening of the air guide cover 21 is connected to the first air duct 12, and the airflow of the first air duct 12 can be led out through the air guide cover 21. The air guide module 20 may also include a swirl structure or a wind guide structure disposed in the air guide cover 21 to diffuse the airflow passing through the air guide cover 21 to form a scattered flow.

[0040] When the deflector 21 moves to protrude from the first air outlet 13, the expansion gap 22 formed between the deflector 21 and the first air outlet 13 extends along the circumference of the deflector 21. When the air conditioner indoor unit is working, part of the air flow flowing to the first air outlet 13 is dispersed inside the deflector 21 and blown out, and the other part flows out from the expansion gap 22. The air outlet direction of the expansion gap 22 is inclined to the opening direction of the first air outlet 13, so that the air outlet angle can be increased and the air outlet range can be expanded. In this way, the air outlet volume is guaranteed and the air outlet with a breeze or no wind feeling is achieved. The first air outlet 13 can be set to a flared shape corresponding to the deflector 21, so that when the deflector 21 retracts backward to the first air outlet 13, it can be integrally abutted against the cavity wall of the first air outlet 13 to improve the integrity of the air conditioner indoor unit.

[0041] The air conditioner indoor unit of the present invention gradually increases the radial size of the guide cover 21 along the air outlet direction, and forms a flow expansion gap 22 between the guide cover 21 and the edge of the first air outlet 13, so that part of the air flow of the first air duct 12 is sent out from the inside of the guide module 20, and the other part can flow out from the flow expansion gap 22. Since the air outlet angle of the flow expansion gap 22 is inclined to the opening direction of the first air outlet 13, the air outlet area can be increased to achieve the effect of dispersing wind. Therefore, the air outlet volume of the air conditioner indoor unit can be increased, and the air outlet effect can be improved.

[0042] like Figure 4 and Figure 6As shown, the drainage module 20 also includes a drainage impeller 23 disposed in the drainage cover 21. In this embodiment, the drainage impeller 23 can rotate relative to the drainage cover 21, or can be fixed relative to the drainage cover 21. When the drainage impeller 23 is fixed relative to the drainage cover 21, the drainage impeller 23 can be driven to rotate by the rotation of the drainage cover 21. The rotation of the drainage impeller 23 can play a swirl diffusion role on the airflow, thereby improving the air outlet effect. Specifically, a support portion located in the middle can be provided in the drainage cover 21, and the support portion is connected to the inner peripheral wall of the drainage cover 21 through spokes, so as to be fixed in the middle of the drainage cover 21, and the drainage impeller 23 can be connected to the support portion to achieve installation in the drainage cover 21.

[0043] The deflector 21 can be rotatably installed at the first air outlet 13. In this embodiment, the deflector 21 can rotate around the central axis of the first air outlet 13 to exert a swirl effect on the airflow flowing through the expansion gap 22, thereby further achieving the effect of expansion. In combination with the above-mentioned embodiment of the deflector impeller 23, the deflector impeller 23 can be fixed relative to the deflector 21, so that when the deflector 21 rotates, it will drive the deflector to rotate together, thereby, the airflow flowing through the inside and outside of the deflector 21 can be exerted with a swirl effect, so as to improve the air outlet effect of all the airflow flowing through the first air outlet 13.

[0044] like Figure 5 and Figure 6 As shown, the air conditioner indoor unit further includes a bracket 30 disposed in the housing 10, and the air guide cover 21 is rotatably matched with the bracket 30. In this embodiment, the bracket 30 is connected to the housing 10 and is located on the inner side of the first air outlet 13, and the inner end of the air guide cover 21 is rotatably matched with the bracket 30 to realize the overall rotation of the air guide cover 21. Specifically, the air guide module 20 further includes a connecting cover 24 connected to the inner end of the air guide cover 21, and the peripheral wall of the connecting cover 24 is provided with an air hole 241 connected to the inner cavity of the air guide cover 21, and the connecting cover 24 is rotatably mounted on the bracket 30 through a bearing 25. The connecting cover 24 is open to the front, and the open end of the connecting cover is connected to the inner end of the air guide cover 21, and the airflow can enter the air guide cover 21 through the air hole 241 on the peripheral wall of the connecting cover 24. The outer ring of the bearing 25 is fixed to the bracket 30 , and the inner ring of the bearing 25 is fixed to the connecting cover 24 , thereby supporting the rotation of the connecting cover 24 and further driving the drainage cover 21 to rotate.

[0045] like Figure 6 As shown, the end wall of the connection cover 24 is provided with an axial hole, and the air conditioner indoor unit further includes a first driving device 70 installed on the bracket 30, and the driving shaft of the first driving device 70 cooperates with the axial hole. In this embodiment, the first driving device 70 can drive the connection cover 24 to rotate, thereby realizing the automatic rotation of the drainage cover 21, and improving the convenience of the drainage module 20 in operation.

[0046] like Figure 5 and Figure 6 As shown, the outer peripheral wall of the guide cover 21 is provided with guide ribs 211. In this embodiment, the specific shape and distribution of the guide ribs 211 are not specifically limited, and it is only necessary to satisfy the requirement of being provided on the outer peripheral wall of the guide cover 21. The guide ribs 211 can further guide the airflow passing through the expansion gap 22, thereby improving the air outlet effect of the expansion gap 22. Specifically, the guide ribs 211 extend in a twisted shape along the axial direction of the guide cover 21, and the guide ribs 211 extend in a twisted shape from the inner end of the guide cover 21 toward the outer end of the guide cover 21, so that the outlet airflow can form a spiral outlet mode, further improving the air outlet effect. In actual applications, the number of the guide ribs 211 is multiple, and the multiple guide ribs 211 are arranged at intervals along the circumference of the guide cover 21, so as to guide all the airflows passing through the expansion gap 22, thereby improving the overall air outlet effect of the guide module 20.

[0047] like Figure 5 and Figure 6 As shown, the drainage module further includes an air outlet grille 26 disposed at the air outlet end of the drainage cover. In this embodiment, the air outlet grille 26 can protect the drainage impeller installed in the drainage cover and also prevent the user from inserting his hand into the drainage cover.

[0048] like Figure 5 and Figure 6 As shown, the bracket 30 is connected to the housing 10 so as to be movable forward and backward. In this embodiment, the bracket 30 and the housing 10 may be connected in a sliding manner, which is not limited here, and only needs to satisfy that the bracket 30 can be movable forward and backward. The forward and backward movement of the bracket 30 drives the drainage module 20 to move forward and backward, which can make the movement process of the drainage module 20 more stable.

[0049] like Figure 6 As shown, the air conditioner indoor unit further includes a second driving device for driving the bracket 30, the second driving device includes a driving motor 41 installed on the housing 10, a gear 42 connected to the driving motor 41, and a rack 43 connected to the bracket 30, the rack 43 meshing with the gear 42. In this embodiment, the rack 43 extends in the front-to-back direction and is connected to the end of the bracket 30, the gear 42 is fixedly matched with the driving shaft of the driving motor 41, so that the operation of the driving motor 41 can drive the bracket 30 to move through the gear 42 and the rack 43. The gear 42 and the rack 43 can improve the structural strength of the second driving device to ensure the stability of the driving process of the bracket 30.

[0050] like Figure 4 and Figure 5As shown, there are multiple first air outlets 13, and the multiple first air outlets 13 are spaced apart along the height direction of the panel 11. The drainage module 20 is provided at each of the first air outlets 13, and the bracket 30 extends along the height direction of the panel 11, and each of the drainage modules 20 is connected to the bracket 30. In this embodiment, each drainage module 20 is connected to the bracket 30, which can simplify the installation structure of multiple drainage modules 20, so that the installation process of the drainage modules 20 is simpler and more convenient.

[0051] like Figure 3 As shown, the shell 10 is further provided with a second air duct 14 and a second air outlet 15 connected to the second air duct 14, and the cavity wall of the second air duct 14 is provided with a diversion port 141 for connecting the first air duct 12 with the second air duct 14; the air conditioner indoor unit also includes a fan 50 and a valve 60, the fan 50 is arranged in the second air duct 14, and the valve 60 can be movably arranged at the diversion port 141 to open or close the diversion port 141.

[0052] In the present embodiment, the fan 50 may be a cross-flow fan 50. Since the fan 50 is installed in the second air duct 14, the airflow generated by the fan 50 mainly flows to the second air outlet 15. The first air duct 12 is adjacent to the second air duct 14 and shares part of the air duct cavity wall. It can be understood that the housing 10 also has a volute and a volute tongue for forming the second air duct 14. The fan 50 is arranged in the volute, and the diversion port 141 can be opened in the volute. The movement mode of the valve 60 can be translation or rotation, which is not limited here, and it is only necessary to satisfy that the valve 60 can open or close the diversion port 141. When the valve 60 opens the diversion port 141, it can be located in the second air duct 14 to divert part or all of the airflow of the second air duct 14 to the first air duct 12. If the air-conditioning indoor unit needs to achieve normal air supply, the valve 60 can be closed and the drainage module 20 can be retracted to the first air outlet 13 so that all the airflow is blown out from the second air outlet 15; if the air-conditioning indoor unit needs to achieve swirl air supply, the valve 60 can be opened and the drainage module 20 can be extended out of the first air outlet 13 so that the airflow is delivered through the drainage module 20 and the flow expansion gap 22, thereby meeting the different air supply needs of users.

[0053] like Figure 3As shown, the number of the second air outlets 15 is two and they are arranged on both sides of the first air outlet 13 in the horizontal direction, the number of the second air ducts 14 is two and they are connected to the two second air outlets 15 respectively, the first air duct 12 is formed between the cavity walls of the two second air ducts 14, the number of the fans 50 is two and they are arranged in the two second air ducts 14, the cavity walls of the two second air ducts 14 are both provided with the diversion ports 141, and the two diversion ports 141 are both provided with the valves 60. In this embodiment, in combination with the above-mentioned embodiment of the volute and volute tongue, the number of the volute and volute tongue can be two groups, the two fans 50 are arranged in the two volutes, the first air duct 12 is arranged between the two volutes, and the rear ends of the two volutes abut against each other so that the outer wall surfaces of the two volutes are enclosed to form the first air duct 12. By setting the air conditioner indoor unit to double cross-flow air outlet, the air outlet area and air outlet range can be further increased under the premise of ensuring the air outlet volume.

[0054] The present invention also provides an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit. The specific structure of the air conditioner indoor unit refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. The air conditioner outdoor unit is connected to the air conditioner indoor unit through a refrigerant pipe.

[0055] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
