[0050] The present application provides an air conditioner indoor unit and an air outlet device thereof. The air conditioner indoor unit is the indoor part of the air conditioner, which is used to adjust the indoor air, such as refrigeration / heat, dehumidification, purification, introduction of fresh air, etc. Specifically, the air conditioner indoor unit can be various forms such as wall-mounted, vertical, etc. Figures 1 to 6 The schematic air conditioner indoor unit is a wall-mounted air conditioner indoor unit.

[0051] Figure 1 is a structural schematic diagram of the air conditioner indoor unit according to an embodiment of the present application; Figure 2 is Figure 1 is a schematic front view of the air conditioner indoor unit shown; Figure 3 is Figure 2 is an enlarged view of the N-N section of the air conditioner indoor unit;

[0052] Figure 4 is Figure 3 is a schematic view of the air conditioner indoor unit shown after the air outlet device 50 rotates 90° clockwise; Figure 5 isFigure 4 The diagram shows the indoor unit of the air conditioner after the air outlet device 50 is rotated 90° clockwise. Figure 6 yes Figure 5 The diagram shows the indoor unit of the air conditioner after the air outlet device 50 has been rotated 90° clockwise. Figure 7 This is a schematic diagram of the structure of an air outlet device 50 according to an embodiment of the present invention. Figures 3 to 6 Only the area near air outlet 12 was cut open; other areas were not cut open.

[0053] In one aspect, the present invention provides an air outlet device 50 for an indoor unit of an air conditioner.

[0054] like Figures 1 to 7 As shown, the air outlet device 50 of this embodiment of the invention is installed at the air outlet 12 of the housing 10 of the indoor unit of the air conditioner. The air outlet 12 is used to deliver the regulated airflow generated by the air conditioner to the indoor environment for regulating the indoor air. The regulated airflow can specifically be one or more of cold airflow, hot airflow, fresh airflow, and purified airflow, or a mixture thereof.

[0055] The air outlet device 50 includes a first air outlet column 51. The first air outlet column 51 is generally columnar, specifically it can be cylindrical, elliptical, polygonal, etc. The installation orientation of the first air outlet column 51 is related to the shape of the air outlet 12. For example, for a floor-standing air conditioner indoor unit, the air outlet 12 can be vertical, so the first air outlet column 51 can be installed vertically. For a wall-mounted air conditioner indoor unit, such as... Figure 1 and Figure 2 If the air outlet 12 is made into a horizontal strip, then the first air outlet column 51 extends in the horizontal direction.

[0056] The first air outlet column 51 has multiple air outlet sections 200. Each air outlet section 200 is used to guide the airflow direction or to process the airflow. The airflow processing includes various methods such as purification, humidification, and aromatherapy. The first air outlet column 51 is configured to rotate about an axis (x1) parallel to its axial direction (x direction) to adjust the relative position of each air outlet section 200 and the air outlet 12, so as to change the air outlet mode of the indoor unit of the air conditioner.

[0057] The air outlet device 50 of the embodiment of the present application comprises a rotatable first air outlet column 51. The first air outlet column 51 comprises a plurality of air outlet portions 200, which makes the air outlet mode of the air conditioner indoor unit more diverse. When the first air outlet column 51 rotates, the relative position of each air outlet portion 200 to the air outlet 12 will be changed, so that part of the air outlet portions 200 face the air outlet 12 to act on the airflow, and the other air outlet portions 200 no longer face the air outlet 12 directly. In this way, the air outlet mode can be changed by rotating the first air outlet column 51 to meet the diversified needs of users. For example, if the air outlet portions 200 of the first air outlet column 51 comprise air outlet portions for purification and air outlet portions for air guiding. When the first air outlet column 51 is rotated to the air outlet portions for purification facing the air outlet 12, the air outlet portions fully play the role of purification, and the air conditioner indoor unit is in a purification mode. When the first air outlet column 51 is rotated to the air outlet portions for air guiding facing the air outlet 12, the air outlet portions fully play the role of air guiding, and the airflow is guided to a preset area, so that the air conditioner indoor unit is in a air supply mode.

[0058] Compared with the traditional air guiding structure such as the air guiding plate and the swing leaf, the air outlet device 50 of the present application has a novel and ingenious structure, higher product differentiation, and overturns the appearance of the air conditioner indoor unit, so that the product has a higher grade and better user experience.

[0059] In some embodiments, the plurality of air outlet portions 200 of the first air outlet column 51 comprises at least one purification sheet 210 and at least one air guiding plate 220. Each purification sheet 210 is configured to purify the airflow penetrating through it, and the air guiding plate 220 is used to guide the direction of the airflow. Specifically, as shown in Figure 2 The number of purification sheets 210 can be multiple and arranged at intervals along the circumference of the first air outlet column 51. The air guiding plate 220 is arranged inside the outer peripheral contour of the first air outlet column 51 to avoid interfering with the shell 10 when the first air outlet column 51 rotates. For example, the number of purification sheets 210 is two, and the air guiding plate 220 is located between the two purification sheets 210. In this way, by adjusting the position of the air outlet device 50, the wall-mounted air conditioner indoor unit can have at least the following air supply modes.

[0060] (1) Cooling air supply mode: this mode can be selected when the air conditioner indoor unit is in cooling operation. Specifically, the air outlet device 50 is kept in any state between Figure 3 and Figure 4 , or reciprocating swing between Figure 3 and Figure 4 . The two purification sheets 210 are respectively close to the two walls of the air duct 15 to no longer block the air outlet 12 directly, and the space between the two purification sheets 210 is used for air outlet, so that the resistance of the air supply airflow to the purification sheets 210 is minimized.

[0061] (2) Cooling and purifying mode: when the air conditioner indoor unit is in cooling operation, this mode can be selected. Specifically, the air outlet device 50 stays at any state near Figure 4 or its vicinity, so that the two purifying sheets 210 block the air outlet 12 directly, and the air deflector 220 has its air deflection surface facing upward, so that the main body of the air outlet flow must pass through the two purifying sheets 210 in sequence and be purified thereby.

[0062] (3) Heating and blowing mode: when the air conditioner indoor unit is in heating operation, this mode can be selected. Specifically, the air outlet device 50 stays at any state between Figure 5 and Figure 6 , or reciprocally swings between Figure 5 and Figure 6 . In this way, the two purifying sheets 210 are respectively close to the two walls of the air duct 15, so as not to block the air outlet 12 directly, and the air deflector 220 has its air deflection surface facing backward, so as to deflect the air downward. The space between the two purifying sheets 210 is used for air outlet, so that the air flow is subjected to the least resistance of the purifying sheets 210.

[0063] (3) Heating and purifying mode: when the air conditioner indoor unit is in heating operation, this mode can be selected. Specifically, the air outlet device 50 stays at any state near Figure 6 or its vicinity, so that the two purifying sheets 210 block the air outlet 12 directly, and the air deflector 220 has its air deflection surface facing downward, so that the main body of the air outlet flow must pass through the two purifying sheets 210 in sequence and be purified thereby.

[0064] In some embodiments, the air outlet device 50 further comprises a driving mechanism 53 for driving the first air outlet column 51 to rotate intermittently. In this way, when the motor 600 of the driving mechanism 53 continuously rotates, the first air outlet column 51 rotates intermittently, i.e. rotates for a while and stops for a while. During the period of stopping and not rotating, the air outlet device 50 maintains the current air outlet mode, so as to have sufficient time to fully play the role of the current air outlet mode, and avoid that the first air outlet column 51 continuously rotates, so that the air outlet mode switches too quickly, and some air outlet modes cannot fully play their roles and advantages.

[0065] Figure 8 is an exploded view of the air outlet device 50 shown in Figure 7 ; Figure 9 is an enlarged view of A in Figure 8 ; Figure 10 is an end surface structure view of the air outlet device 50; Figure 11 is a schematic view of the air outlet device 50 shown in Figure 10 when the pushing part 713 is about to enter the guide groove 101; Figure 12 is a schematic view of the air outlet device 50 shown in Figure 11 when the pushing part 713 enters the guide groove 101 and the line connecting the rotating shaft 730 and the pushing part 713 is parallel to the length direction of the guide groove 101; Figure 13 isFigure 12 This is a schematic diagram of the air outlet device 50 when the pusher 713 moves in the reverse direction to the first end of the guide groove 101.

[0066] In some embodiments, such as Figure 8 and Figure 9 As shown, the drive mechanism 53 may specifically include a motor 600 and a rotating member 700. The rotating member 700 is driven by the motor 600 to rotate around a fixed axis and has a pushing portion 713 spaced apart from the rotating shaft 730. The pushing portion 713 is preferably a columnar structure parallel to the rotating shaft 730. Alternatively, it may be spherical or other shapes. The first end face 108 of the first air outlet column 51 is provided with a plurality of guide grooves 101 arranged circumferentially thereon. Each guide groove 101 extends radially along the first end face 108 and has a first end E1 near the center of the first end face 108 and a second end E2 near the periphery of the first end face 108. The first end E1 has an opening 102.

[0067] The air outlet device 50 is configured such that when the motor 600 drives the rotating member 700 to rotate, the pushing part 713 enters the guide groove 101 through the opening 102 and moves along the guide groove 101 toward the second end E2 to push the first air outlet column 51 to rotate. When the line connecting the rotating shaft 730 and the pushing part 713 is parallel to the length direction of the guide groove 101, the pushing part 713 changes direction and moves toward the first end E1 to push the first air outlet column 51 to continue rotating. After the pushing part 713 leaves the guide groove 101 through the opening 102, the first air outlet column 51 stops rotating. When the rotating member 700 continues to rotate so that the pushing part 713 enters the next guide groove 101, the first air outlet column 51 is pushed to continue rotating.

[0068] The following is for reference. Figures 10 to 11 The above process will be explained in detail.

[0069] like Figure 10 As shown, the first air outlet column 51 includes four guide grooves 101, which are respectively formed on the four radial rods 112, 113, 114, and 115 of the first air outlet column 51, with each adjacent guide groove 101 spaced 90° apart. Figure 10 In the indicated state, the rotating member 700 rotates clockwise, causing the pushing part 713 to disengage from the guide groove 101 of the radial rod 114. Then it rotates to... Figure 11 Status. In Figures 10 to 11 Between states, rotating component 700 rotates, but the first exhaust column 51 does not rotate. Rotating component 700 arrives... Figure 11 After reaching the desired state, the rotation continues, causing the pushing part 713 to enter the guide groove 101 of the radial rod 113 through the opening 102 at the first end E1. As it continues to rotate clockwise, it pushes one wall of the guide groove 101, thereby causing the first air column 51 to rotate clockwise. During this process, the pushing part 713 gradually approaches the second end E2 until... Figure 12the state (the line connecting the rotating shaft 730 and the pushing part 713 is parallel to the length direction of the guide groove 101). At this time, the rotating part 700 continues to rotate clockwise, the pushing part 713 turns to the first end El, moves and continues to push the groove wall of the guide groove 101, and further rotates the first air outlet column 51 clockwise until Figure 13 the state.

[0070] In Figure 13 the state, the rotating part 700 continues to rotate clockwise, and the pushing part 713 is separated from the guide groove 101 of the radial rod 113, and then enters the guide groove 101 of the radial rod 112 to repeat the above process. Since four guide grooves 101 are provided, the first air outlet column 51 rotates 90° when the rotating part 700 rotates one circle. The first air outlet column 51 stops four times during one circle. The above structure is used to realize the intermittent rotation of the first air outlet column 51 driven by the continuous rotation of the rotating part 700. Of course, the number of guide grooves 101 is not limited to four, and can be more.

[0071] In some embodiments, as shown in Figure 9 , the rotating part 700 can include a connecting rod part 710, a rotating shaft 730, a pushing part 713, and a counterweight part 720. The connecting rod part 710 is rod-shaped. The rotating shaft 730 and the pushing part 713 extend in opposite directions from the two ends of the connecting rod part 710, so that the rotating part 700 is located between the motor 600 and the guide groove 101, and the rotating shaft 730 and the pushing part 713 extend towards the motor 600 and the guide groove 101, respectively. The counterweight part 720 is connected to the end of the connecting rod part 710 provided with the rotating shaft 730, so as to improve the rotational inertia and structural strength of the rotating part 700, and make the rotation of the rotating part 700 more stable. Specifically, the connecting rod part 710, the rotating shaft 730, the pushing part 713, and the counterweight part 720 can form an integrally formed whole.

[0072] In some embodiments, as shown in Figure 8 , the first air outlet column 51 can further include a columnar frame 100 for mounting a plurality of air outlet parts 200, and the columnar frame 100 includes two disc bodies 110, 120 and a plurality of connecting strips 130. The two disc bodies 110, 120 respectively constitute the axial two end portions of the first air outlet column 51, and the outer end face of one of the disc bodies 110 constitutes the aforementioned first end face 108. The plurality of connecting strips 130 are respectively connected between the two disc bodies 110, 120 and are arranged in a spaced apart manner along the circumferential direction of the first air outlet column 51. Each purification sheet 210 is connected between two adjacent connecting strips 130. Referring to Figure 3 and Figure 8 , the number of connecting strips 130 can be four, and the number of purification sheets 210 can be two. One of the two connecting strips 130 is provided with a purification sheet 210, and the remaining two connecting strips 130 are provided with another purification sheet 210.

[0073] As Figure 9 shown, the disc body 110, 120 constituting the first end surface can include an outer ring 111 and a center disc 117 located inside the outer ring 111. Each radial rod 112, 113, 114, 115 is connected between the outer ring 111 and the center disc 117. A plate body 118 is arranged between two adjacent radial rods, the outer edge of the plate body 118 is connected to the outer ring 111, and the inner edge is arc-shaped. The counterweight part 720 can have a fan-shaped structure, the edge away from the rotation axis 730 is arc-shaped, and the diameter is smaller than the diameter of the inner edge of the plate body 118.

[0074] In some embodiments, the air outlet device 50 can further include one second air outlet column 52 or a plurality of second air outlet columns 52 arranged in series in the axial direction, and each second air outlet column 52 is arranged in series in the axial direction with the first air outlet column 51.

[0075] Specifically, as Figure 1 , Figure 7 and Figure 8 shown, the number of second air outlet columns 52 is one. The first air outlet column 51 and the second air outlet column 52 are fixedly connected through the total shaft 55, and the two ends A, B (see Figure 7 ) of the total shaft 55 are rotatably mounted to the shell 10 of the air conditioner indoor unit.

[0076] In this way, the first air outlet column 51 can drive the second air outlet column 52 to rotate. Each second air outlet column 52 includes a plurality of air outlet parts 200 arranged in the circumferential direction thereof. Each air outlet part 200 is used to guide the airflow direction or process the airflow. The processing of the airflow includes various modes such as purification, humidification, aromatherapy, etc. In this way, the types, numbers, sizes, arrangement modes or phases of the air outlet parts 200 of different air outlet columns can be designed to be different, so that the air outlet 12 has multiple air outlet modes at the same time. Figures 1 to 8 In the illustrative embodiment, the second air outlet column 52 is completely identical to the first air outlet column 51 in the arrangement mode of the air outlet parts 200. The specific structure of the second air outlet column 52 is referred to the first air outlet column 51, which will not be described here.

[0077] As Figure 8 shown, one side of the air guide plate 220 in the width direction is mounted to the total shaft 55, and the other side is fixed to a connecting strip 130.

[0078] Another aspect of the present application also provides an air conditioner indoor unit. As Figures 1 to 6As shown, the air conditioner indoor unit comprises a shell 10 and the air outlet device 50 as described in any of the above embodiments. The shell 10 is provided with an air outlet 12. The air outlet device 50 is arranged at the air outlet 12. The air conditioner can be composed of an evaporator, a condenser, a compressor, a throttling device and other necessary elements to form a vapor compression refrigeration cycle system, so as to output cold air / warm air by the fan to achieve cooling and heating of the indoor environment. A duct 15 can be formed in the shell 10, and the outlet of the duct 15 is connected to the air outlet 12.

[0079] At this point, those skilled in the art should recognize that, although the present application has been fully illustrated and described herein with a plurality of exemplary embodiments, many other variations or modifications in accordance with the principles of the present application can be directly determined or deduced from the disclosure of the present application without departing from the spirit and scope of the present application. Therefore, the scope of the present application should be understood and recognized as covering all such other variations or modifications.
