[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] like Figures 1 to 22 As shown, the present invention provides an air guide mechanism, including: a transmission assembly 20, the transmission assembly 20 includes a rotating shaft 1 and a plurality of rocker arms 2 arranged at intervals along the axial direction of the rotating shaft 1, each rocker arm 2 is used to be connected to an air guide plate 4, and the rotating shaft 1 is movably arranged at the upper edge of an air outlet 50; a limiting structure, the limiting structure having a limiting space 40, at least a portion of each rocker arm 2 is located in the limiting space 40, so as to limit the movement of the rocker arm 2 through the limiting space 40.

[0059] The air guiding mechanism of the present invention arranges the transmission assembly 20 at the upper edge of the air outlet 50, and limits the movement of the swing rod 2 of the transmission assembly 20 through a limiting structure with a limiting space 40. On the one hand, it enables the air guiding plate 4 of the transmission assembly 20 to move to a higher position above the air outlet, so that the air direction of the air outlet 50 blows to a higher position, avoiding the phenomenon of cold air blowing directly at people, and solving the problem of poor comfort performance of the air conditioner in the prior art. On the other hand, it can effectively ensure the movement reliability of the transmission assembly 20 to prevent the transmission assembly 20 from rotating excessively.

[0060] As Figure 2 shown, an air outlet 50 is provided on the bottom case 10. The bottom case 10 includes an upper edge 106 and a lower edge 105 for enclosing the air outlet 50. The upper edge 106 is located on the side of the lower edge 105 away from the ground. The rotating shaft 1 is located at a position close to the upper edge 106 of the air outlet 50, and both ends of the rotating shaft 1 are connected to the bottom case 10. It can be seen that the "upper edge" mentioned in the present invention refers to the side of the upper wall surface of the air outlet away from the lower wall surface of the air outlet (including the case where the axis of the rotating shaft 1 is located in the plane or curved surface of the upper wall surface of the air outlet).

[0061] The direction word "upper" in the "upper edge" referred to in this application is the orientation when the air guiding mechanism is in the installed state (i.e., the using state).

[0062] As Figure 21 shown, it is a schematic structural diagram of the transmission assembly 20 of the air guiding mechanism of the present invention when the air guiding plate 4 is installed.

[0063] Specifically, the air conditioner of the present invention is a wall-mounted air conditioner.

[0064] Specifically, the limiting structure includes a limiting component and a supporting component. Both the limiting component and the supporting component are arranged on the bottom case 10 with the air outlet 50, and the limiting component and the supporting component enclose the limiting space 40. In this way, the movement of the swing rod 2 is limited through the combined action between the limiting component and the supporting component.

[0065] Specifically, the limiting component is detachably installed on the supporting component. In this way, it is convenient for maintenance and replacement of the limiting component, reducing the after-sales cost of the air guiding mechanism.

[0066] Specifically, the limiting component further includes a limiting part 3, and the supporting component includes a supporting part 102 connected to the limiting part 3, so as to install the limiting component on the supporting component through the connection between the limiting part 3 and the supporting part 102.

[0067] Specifically, there are multiple limiting components 3 and multiple supporting components 102, and the multiple limiting components 3 and the multiple supporting components 102 are arranged in one-to-one correspondence; at least part of each swing rod 2 is arranged between the corresponding limiting component 3 and supporting component 102. In this way, the movement of the corresponding swing rod 2 can be limited by each limiting component 3 and the corresponding supporting component 102.

[0068] Specifically, the limiting component 3 includes a limiting main body 33 and a first connecting portion 34 connected to the limiting main body 33; the supporting component 102 includes a supporting main body 1023 and a third connecting portion 1024 arranged on the supporting main body 1023; wherein, the first connecting portion 34 is connected to the third connecting portion 1024 to position the movement of the limiting component along the first positioning direction.

[0069] Optionally, one of the first connecting portion 34 and the third connecting portion 1024 is a buckle 340, and the other of the first connecting portion 34 and the third connecting portion 1024 is a slot 10240, and the buckle 340 and the slot 10240 are snap-connected. In this way, the buckle 340 and the slot 10240 cooperate with each other and the hook of the buckle 340 can be snap-connected with the slot 10240.

[0070] Preferably, the fitting clearance between the hook wall of the hook 3401 of the buckle 340 and the hole wall of the slot 10240 is 0.08 mm to 0.15 mm.

[0071] As Figure 22 shown, the fitting clearance L between the hook wall of the hook 3401 and the hole wall on the side of the corresponding slot 10240 close to the limiting main body 33 is 0.08 mm to 0.15 mm. In this way, while ensuring the reliability of the connection between the limiting component 3 and the corresponding supporting component 102, it is beneficial to the processing, disassembly and assembly of the limiting component 3 and the supporting component 102, so as to facilitate the replacement and maintenance of the limiting component 3 and the transmission component 20.

[0072] Specifically, the limiting component 3 includes a second connecting portion 35 connected to the limiting main body 33, the supporting component 102 includes a fourth connecting portion 1025 arranged on the supporting main body 1023, and the second connecting portion 35 and the fourth connecting portion 1025 are connected to position the movement of the limiting component 3 along the second positioning direction; wherein, the first positioning direction and the second positioning direction are opposite.

[0073] Specifically, the first positioning direction and the second positioning direction are parallel to the plate body of the corresponding limiting main body 33 and are opposite to each other. By positioning the limiting component 3 in these two opposite directions of the first positioning direction and the second positioning direction, the stable connection between the limiting component 3 and the corresponding supporting component 102 can be ensured.

[0074] Optionally, one of the second connecting portion 35 and the fourth connecting portion 1025 is an abutting portion 350, and the other of the second connecting portion 35 and the fourth connecting portion 1025 is a stop portion 10250, and the abutting portion 350 abuts against the stop portion 10250.

[0075] Specifically, the abutting portion 350 is a protruding portion, and the stop portion 10250 is a groove portion that cooperates with the protruding portion, and the protruding portion is inserted into the groove portion. In this way, the movement of the corresponding protruding portion along the second positioning direction can be stopped by the groove wall surface of the groove portion.

[0076] As Figures 4 to 20 shown, the limiting main body 33 is a plate body, the first connecting portion 34 is arranged at the upper end of the limiting main body 33, and the second connecting portion 35 is arranged at the lower end of the limiting main body 33; and / or the first connecting portion 34 is a buckle 340, and the third connecting portion is a card slot 10240 that cooperates with the buckle 340; the second connecting portion 35 is an abutting portion 350, and the fourth connecting portion 1025 is a stop portion 10250 that cooperates with the abutting portion 350, and the abutting portion 350 is located below the stop portion 10250.

[0077] Specifically, the first connecting portion 34 is a buckle 340 arranged at the upper end of the limiting main body 33; the third connecting portion 1024 is a card slot 10240 arranged on the supporting main body 1023; the buckle 340 and the card slot 10240 are correspondingly arranged, so that the upper end of the limiting component 3 is connected to the supporting component 102 through the engagement of the hook 3401 of the buckle 340 and the corresponding card slot 10240; the second connecting portion 35 is a protruding portion arranged at the lower end of the limiting main body 33 and protruding towards the corresponding swing rod 2; the fourth connecting portion 1025 is a groove portion arranged below the supporting main body 1023; the protruding portion and the groove portion are correspondingly arranged, and the protruding portion is used to be inserted into the corresponding groove portion, so that the lower end of the limiting component 3 is connected to the supporting component 102, so as to ensure the reliability of the assembly between the limiting component 3 and the corresponding supporting component 102.

[0078] Specifically, the buckle 340 includes an elastic plate 3402 and a hook 3401, and the hook 3401 is connected to the limiting main body through the elastic plate 3402; the card slot 10240 is arranged on the supporting plate 10231, the elastic plate 3402 is located above the supporting plate 10231, and the hook 3401 is snapped into the corresponding card slot 10240 from top to bottom.

[0079] Specifically, the plate body of the limiting main body 33 is perpendicular to the supporting plate 10231.

[0080] As Figures 13 to 20As shown, the limiting structure includes a plurality of limiting components 3, and the plurality of limiting components 3 are arranged in one-to-one correspondence with the plurality of swing rods 2; each limiting component 3 includes a limiting main body 33 and a limiting protrusion 36 located on the limiting main body 33. The limiting protrusion 36 protrudes towards the swing rod 2 relative to the limiting main body 33 to form a limiting space 40.

[0081] As Figures 13 to 20 shown, each limiting component 3 includes a limiting main body 33 and a limiting protrusion 36 located on the limiting main body 33. The limiting protrusion 36 protrudes towards the corresponding supporting component 102 and is used to contact the corresponding swing rod 2 to limit the movement of the swing rod 2 in the first swinging direction (i.e., the direction close to the corresponding limiting protrusion 36).

[0082] Specifically, the limiting protrusion 36 is arranged at one end of the limiting main body 33 close to the second connecting portion 35 and protrudes towards the supporting main body 1023. The protruding portion is arranged on one side or opposite sides of the limiting protrusion 36 of the corresponding limiting component 3. The arrangement of the protruding portion and the groove portion forms a sealing structure with a rabbet fit, so as to obstruct the airflow on one side or opposite sides of the limiting protrusion 36, and minimize the phenomenon of condensation above the air outlet 50 of the bottom case 10 due to the airflow passing through the gaps on one side or opposite sides of the limiting protrusion 36 to reach above the air outlet 50 of the bottom case 10.

[0083] Specifically, the limiting structure further includes a plurality of supporting components 102, and the plurality of supporting components 102 are arranged in one-to-one correspondence with the plurality of limiting components 3. The supporting component 102 has a supporting plate 10231, and the supporting plate 10231 is arranged opposite to the limiting protrusion 36 to enclose the limiting space 40.

[0084] Specifically, the limiting protrusion 36 of each limiting component 3 is used to limit the movement of the swing rod 2 in the first swinging direction, and the supporting plate 10231 of each supporting component 102 is used to limit the movement of the swing rod 2 in the second swinging direction (i.e., the direction close to the corresponding supporting plate 10231). The first swinging direction and the second swinging direction are opposite to each other. By setting the limiting protrusion 36 and the supporting plate 10231, the purpose of limiting the swinging of the swing rod 2 in both forward and reverse directions is achieved, so as to ensure that the swing rod 2 will not rotate excessively.

[0085] Specifically, the limiting main body 33 is a plate body, and the limiting protrusion 36 is a U-shaped plate, and the opening of the U-shaped plate faces away from the swing rod 2.

[0086] Specifically, the U-shaped plate includes a first plate body part, a second plate body part, and a third plate body part that are connected in sequence. The first plate body part is perpendicular to the second plate body part, the first plate body part is parallel to the third plate body part, and the second plate body part is parallel to the plate body of the limiting main body 33. The first plate body part is connected to the limiting main body 33, the second plate body part is located on the side of the first plate body part away from the limiting main body 33, and the third plate body part is located on the side of the second plate body part away from the first plate body part and below the limiting main body 33 and the first plate body part, so as to form a limiting protrusion 36 that protrudes on the side of the limiting main body 33 facing the corresponding swing rod 2 and is located below the limiting main body 33. While limiting the movement of the swing rod 2 in the first swing direction, it can also prevent the airflow below the limiting main body 33 from directly entering the corresponding limiting area 401.

[0087] Specifically, the limiting structure includes a plurality of limiting components 3 and a plurality of supporting components 102. The plurality of limiting components 3 and the plurality of supporting components 102 are both used to form a limiting space 40. The supporting component 102 has a first wind shield 10232, and each limiting component 3 includes a second wind shield 331. At least a part of the second wind shield 331 is located on one side of the first wind shield 10232, so as to block the airflow in the limiting space 40 through the first wind shield 10232 and the second wind shield 331.

[0088] Specifically, the plurality of supporting components 102 includes two first supporting components 1022 and at least one second supporting component 1021 located between the two first supporting components 1022. Each supporting component 102 is arranged on the bottom case 10 having an air outlet 50. The bottom case 10 has two rotating shaft mounting plates 104, and the two rotating shaft mounting plates 104 are respectively arranged corresponding to the two first supporting components 1022. Each rotating shaft mounting plate 104 is arranged opposite to the corresponding first wind shield 10232. The second supporting component 1021 has two first wind shields 10232 arranged opposite to each other.

[0089] Specifically, the limiting space 40 includes a plurality of limiting areas 401, and each limiting area 401 is arranged in one-to-one correspondence with each swing rod 2. One limiting component 3 and one supporting component 102 form one limiting area 401. Among them, the first wind shield 10232 and the rotating shaft mounting plate 104 of the first supporting component 1022 are respectively located on opposite sides of the corresponding limiting area 401. The two first wind shields 10232 of the second supporting component 1021 are respectively located on opposite sides of the corresponding limiting area 401.

[0090] Specifically, the multiple limiting components 3 include two first limiting components 32 and at least one second limiting component 31 located between the two first limiting components 32; the second wind baffle 331 of the first limiting component 32 is located on the side of the corresponding first wind baffle 10232 away from the corresponding rotating shaft mounting plate 104; the second limiting component 31 includes two second wind baffles 331, and the two second wind baffles 331 of the second limiting component 31 are located outside the two first wind baffles 10232 of the corresponding second support component 1021.

[0098] Specifically, the first shaft hole 3310 on each second wind shield plate 331 is arranged corresponding to the second shaft hole 102320 on the corresponding first wind shield plate 10232 to avoid the rotating shaft 1.

[0099] Specifically, the give-way portion 330 includes a first give-way portion for avoiding the corresponding rocker arm 2 and a second give-way portion for avoiding the rotating shaft 1. The first give-way portion and the second give-way portion are both groove portions that are recessed in a direction away from the transmission assembly 20. The groove portions are both groove structures with openings, so as to ensure the reliability of the movement of the transmission assembly 20 while ensuring the reliability of the assembly method of the transmission assembly 20.

[0100] Preferably, the fitting clearance between the first shaft hole 3310 and the rotating shaft 1 is 0.5 mm to 1.5 mm; and / or the fitting clearance between the second shaft hole 102320 and the rotating shaft 1 is 0.5 mm to 1.5 mm.

[0102] like Figure 3 and Figure 8 As shown, the rotating shaft 1 is passed through the second supporting component 1021, and a stop structure 11 is provided on the rotating shaft 1. The stop structure 11 is arranged corresponding to the second supporting component 1021, and the two end faces of the stop structure 11 along the axial direction of the rotating shaft 1 are limitedly matched with the two first wind shields 10232 of the second supporting component 1021.

[0104] Preferably, the matching clearance between each end surface of the stop structure 11 and the corresponding first windshield plate 10232 is 0.3mm to 0.6mm. In this way, while leaving enough movement clearance for the relative movement between the rotating shaft 1 and the second support component 1021, the movement of the rotating shaft 1 in the axial direction can also be stopped.

[0105] Specifically, the stop structure 11 is a bushing structure sleeved on the rotating shaft 1 or the stop structure 11 is a stepped shaft structure provided on the rotating shaft 1.

[0106] The present invention provides a bottom shell structure, including a bottom shell 10 and a wind guiding mechanism provided on the bottom shell 10, and the wind guiding mechanism is the above-mentioned wind guiding mechanism.

[0107] Specifically, the wind guiding mechanism is the above-mentioned wind guiding mechanism, and the support assembly of the limiting structure is integrally formed with the bottom shell 10.

[0108] Specifically, a plurality of avoidance grooves 101 for avoiding a plurality of swing rods 2 are provided at the upper edge of the air outlet 50 of the bottom shell 10. The plurality of avoidance grooves 101 are arranged in one-to-one correspondence with the plurality of swing rods 2.

[0109] As Figure 3 and Figure 9 shown, a wire outlet hole 103 is provided on the bottom shell 10. The wire outlet hole 103 is provided on the upper side of the air outlet 50 so that a driving component for drivingly connecting with the wind guiding mechanism can be connected to the main control board through a wire passing through the wire outlet hole 103.

[0110] Specifically, the wire outlet hole 103 is located on the right side of the bottom shell 10, and the aperture of the wire outlet hole 103 is relatively large to ensure that the wire of the driving component for driving the transmission assembly 20 to act can be connected to the main control board of the controller of the air conditioner through the wire outlet hole 103.

[0111] The present invention provides an air conditioner, including the above-mentioned bottom shell structure.

[0112] Specifically, the air conditioner is a wall-mounted air conditioner.

[0113] The present invention further provides a method for the movement of a wind guiding plate, including: making the rotation axis of the wind guiding plate 4 located at the upper edge of the air outlet and limiting the movement amplitude of the wind guiding plate 4.

[0114] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0115] The air guiding mechanism of the present invention arranges the transmission component 20 at the upper edge of the air outlet 50, and limits the movement of the swing rod 2 of the transmission component 20 through a limiting structure with a limiting space 40. On the one hand, it enables the air guiding plate (not shown in the figure) of the transmission component 20 to move to a higher position above the air outlet, so that the air flow direction of the air outlet 50 blows to a higher position, avoiding the phenomenon of direct blowing of cold air, and solving the problem of poor comfort performance of the air conditioner in the prior art. On the other hand, it can effectively ensure the movement reliability of the transmission component 20 to prevent the transmission component 20 from rotating excessively.

[0116] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
