[0048] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0049] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings. The air conditioner 100 is used to adjust the temperature or humidity of an indoor air environment. The air conditioner 100 can be divided into a split air conditioner and an integrated air conditioner. The integrated air conditioner can be a window air conditioner or a mobile air conditioner. The split air conditioner includes an indoor unit and an outdoor unit. In the following description, the air conditioner 100 is specifically an indoor unit. The effect is described as an example.

[0050] like Figure 1 and Figure 5 As shown, the air conditioner 100 according to the embodiment of the present invention comprises a housing 1, a plurality of air guide grille components 3 and at least one driving motor 4. In the description of the present invention, the meaning of "plurality" includes two or more than two.

[0051] like Figure 1 and Figure 2 As shown, a plurality of spaced-apart air outlets 111 are provided on the front panel 11 of the housing 1, so that the airflows blown out from each air outlet 111 do not affect each other, thus avoiding affecting the air supply effect of the air conditioner 100. After such arrangement, compared with a single air outlet 111 in the related art, the air conditioner 100 can have a larger air outlet area, thereby enabling the air conditioner 100 to have a larger air supply range. For some air conditioners 100 with a windless function, it is beneficial to improve the cooling capacity of the air conditioner 100 in the windless mode. In the description of the present invention, when the user is facing the front panel 11, the direction close to the user is the front, and the direction away from the user is the back.

[0052] Optionally, the number of air outlets 111 is not less than four. In specific applications, the arrangement of the multiple air outlets 111 is not limited and should be flexibly selected according to actual needs and processing difficulty. For example, the multiple air outlets 111 may be arranged in a linear manner (for example, the multiple air outlets 111 may be arranged evenly spaced in a straight line along the up and down directions or the left and right directions), or the multiple air outlets 111 may be arranged in a planar manner (for example, the multiple air outlets 111 may be evenly spaced in a rectangular area or a circular area). For example, in some embodiments of the present invention, the multiple air outlets 111 are divided into multiple groups of air outlet groups along the up and down directions, and each air outlet group includes two air outlets 111 spaced apart along the left and right directions. Specifically, referring to Figure 1 and Figure 2A total of six air outlets 111 are provided on the front panel 11, and the six air outlets 111 are divided into three groups of air outlet groups distributed vertically. Each air outlet group includes two air outlets 111 spaced apart in the left and right directions. The two air outlets 111 are symmetrical along the length center line of the air conditioner 100, thereby having a simple structure and beautiful appearance.

[0053] like Figure 5 As shown, multiple air guide grille components 3 are rotatably arranged in the casing 1 and correspond one-to-one to multiple air outlets 111. The rotation center line of each air guide grille component 3 extends in the front-to-back direction, so that the wind direction of the corresponding air outlet 111 can be adjusted by rotating the air guide grille, thereby enriching the air supply form of the air conditioner 100 and improving the air supply effect of the air conditioner 100 to meet the needs of users in different usage scenarios.

[0054] Alternatively, if Figure 4 and Figure 5 As shown, the air conditioner 100 further includes a plurality of mounting plates 2, each of which is provided with at least one vent 21, each mounting plate 2 is spaced apart from the front panel 11 to define a storage space 22, a plurality of air guide grille components 3, a plurality of vents 21 and a plurality of air outlets 111 correspond one to one, and each air guide grille component 3 is rotatably disposed in the storage space 22 defined by the mounting plate 2 where the corresponding vent 21 is located. Thus, the wind direction of the corresponding air outlet 111 can be adjusted by rotating the air guide grille, thereby enriching the air supply form of the air conditioner 100. It can be understood that when a plurality of vents 21 are provided on the mounting plate 2, the storage space 22 defined by the mounting plate 2 and the front panel 11 has a plurality of air guide grille components 3 that correspond one to one to the vents 21 on the mounting plate 2.

[0055] Specifically, for example, refer to Figure 4 and Figure 5, three mounting plates 2 and six air guide grille components 3 are arranged inside the housing 1, the three mounting plates 2 are located at the rear side of the front panel 11 and are distributed vertically, each mounting plate 2 is spaced apart from the front panel 11 to define a receiving space 22, wherein the three mounting plates 2 correspond to the three groups of air outlets, each mounting plate 2 is provided with two vents 21 spaced apart in the left-right direction, every two air guide grille components 3 are arranged in one receiving space 22, six vents 21, six air guide grille components 3 correspond to six air outlets 111, so that airflow can flow from the vents 21 to the air guide grille components 3, be guided by the air guide grille components 3 and then blow out from the air outlets 111, each air guide grille component 3 can rotate, and the rotation center line of the air guide grille component 3 extends in the front-back direction, thereby enriching the air supply form of the air conditioner 100. This installation method is simple and convenient, and after the air guide grille component 3 is arranged in the receiving space 22, the mounting plate 2 and the front panel 11 can also play a certain protective role on the grille. Of course, after reading this application, it can be understood that the air outlets 111 can have other arrangements, and the number of mounting plates 2 can be less than the number of air outlet groups.

[0056] In actual applications, in order to reduce the installation steps of the whole machine and improve the installation efficiency, in some embodiments, at least two installation plates 2 are connected as one, and at most all the installation plates 2 are connected as one.

[0057] like Figure 5 and Figure 7As shown, the number of driving motors 4 is less than the number of air guide grille components 3, and multiple air guide grille components 3 are driven to rotate by at least one driving motor 4. For example, when there is one driving motor 4, all air guide grille components 3 are driven to rotate by one driving motor 4; when there are multiple driving motors 4, several air guide grille components 3 are driven to rotate by one driving motor 4, and the remaining air guide grille components 3 are driven by different driving motors 4, or each driving motor 4 drives multiple air guide grille components 3 to rotate, or several of the multiple driving motors 4 drive multiple air guide grille components 3 to rotate, and the remaining driving motors 4 drive one air guide grille component 3 to rotate. Therefore, compared with the arrangement in which each air guide grille component 3 is independently driven by a single drive motor 4, this structural form can reduce the number of drive motors 4 used, thereby reducing the driving cost of the air conditioner 100, making the air conditioner 100's electronic control of the drive motor 4 more reliable, and reducing the installation space 26 occupied by the drive motor 4 as a whole, which is conducive to making the structure of the air conditioner 100 more compact and simplifying the installation steps of the whole machine; in addition, the direction and speed of different drive motors 4 can be different, so that the air conditioner 100 can achieve more dimensional air supply. In the mode in which the drive motor 4 drives the air guide grille component 3 to rotate continuously, the air conditioner 100 can also achieve more turbulent air supply, which can improve the air flow disturbance and temperature uniformity of the indoor environment.

[0058] According to the air conditioner 100 of the embodiment of the present invention, since a plurality of spaced-apart air outlets 111 are provided on the front panel 11 of the casing 1, the air conditioner 100 can have a larger air outlet area and a larger air supply range; since a rotatable air guide grille component 3 is provided in the casing 1, the wind direction of the corresponding air outlet 111 can be adjusted to enrich the air supply form of the air conditioner 100 and improve the air supply effect of the air conditioner 100; since the number of drive motors 4 is less than the number of air guide grille components 3, the number of drive motors 4 used can be reduced, thereby reducing the driving cost of the air conditioner 100, making the air conditioner 100 more reliable in terms of the electronic control of the drive motor 4, and reducing the installation space 26 occupied by the drive motor 4 as a whole, which is conducive to making the structure of the air conditioner 100 more compact and simplifying the installation steps of the whole machine.

[0059] In order to facilitate the description of the driving relationship between the plurality of air guide grille components 3 and the driving motor 4, the following will describe the cases where the number of the driving motor 4 is one and the number of the driving motor 4 is multiple.

[0060] When there are multiple drive motors 4, Figure 7As shown, in some embodiments of the present invention, a plurality of air guide grille components 3 are divided into a plurality of air guide grille component groups 3a, at least one group of air guide grille component groups 3a includes a plurality of air guide grille components 3, a plurality of driving motors 4 correspond one-to-one to the plurality of air guide grille component groups 3a, and each driving motor 4 is used to drive the air guide grille component 3 of the corresponding air guide grille component group 3a to rotate.

[0061] Specifically, for example, refer to Figure 7 In this embodiment, there are six air guide grille components 3 and three driving motors 4. The six air guide grille components 3 can be divided into three groups of vertically arranged air guide grille component groups 3a. Each group of air guide grille component groups 3a corresponds to a driving motor 4. Each group of air guide grille components 3 includes two air guide grille components 3 arranged in the left and right directions. The two air guide grille components 3 can be driven to rotate by corresponding driving motors 4. In practical applications, the three driving motors 4 can have different working states (such as different directions and speeds), so that the air outlet form of the air conditioner 100 can be more diversified to better match the working mode of the air conditioner 100 and improve the air supply effect of the air conditioner 100.

[0062] Furthermore, if Figure 7 As shown, the air guide grille component group 3a including multiple air guide grille components 3 is called the first air guide grille component group 3b, each air guide grille component 3 of the first air guide grille component group 3b includes an annular outer ring 32 and multiple grille bars 33 arranged in the outer ring 32, and a rack 6 is provided on the outer peripheral wall of the outer ring 32, and the rack 6 extends along the circumferential direction of the air guide grille component 3. In the first air guide grille component group 3b, the racks 6 of any two adjacent air guide grille components 3 (for example, two adjacent air guide grille components 3 in other directions such as the left-right direction or the up-down direction) are meshed, so that the rotation directions of the two air guide grille components 3 are opposite, and the motor shaft of the driving motor 4 is connected to one of the air guide grille components 3, so that the air guide grille component 3 connected to the driving motor 4 serves as the active air guide grille component 3c in the first air guide grille component group 3b, to drive the remaining air guide grille components 3 (that is, the driven air guide grille components 3d) in the first air guide grille component group 3b to rotate.

[0063] Specifically, for example, refer to Figure 6 and Figure 7Each group of air guide grille component groups 3a is a first air guide grille component group 3b. The first air guide grille component group 3b includes two air guide grille components 3 arranged in the left-right direction. Each air guide grille component 3 includes an inner ring 31, an outer ring 32 and a plurality of grille bars 33. The inner ring 31 and the outer ring 32 are both annular. The outer ring 32 surrounds the inner ring 31 and is coaxially arranged. The inner peripheral wall of the outer ring 32 is spaced apart from the outer peripheral wall of the inner ring 31. The plurality of grille bars 33 are spaced apart between the outer ring 32 and the inner ring 31. The rack 6 is annular and is sleeved on the outer peripheral wall of the outer ring 32. Thus, the structure is simple and easy to implement. The racks 6 of the two adjacent air guide grille components 3 in the left-right direction mesh with each other. The right air guide grille component 3 is an active air guide grille component 3c, and the left air guide grille component 3 is a driven air guide grille component 3d.

[0064] It is understandable that the air guide grille component 3 may also be in other shapes, which should be selected according to actual needs, and the present invention does not limit this.

[0065] In practical applications, the driving motor 4 can directly drive the active air guide grille component 3c to rotate. For example, in some embodiments of the present invention, a pivot hole is provided at the central axis of the active air guide grille component 3c, and the motor shaft of the driving motor 4 is plugged into the pivot hole, so that the driving motor 4 can directly drive the air guide grille component 3 to rotate.

[0066] Alternatively, the driving motor 4 may also indirectly drive the air guide grille component 3 to rotate. Figure 7 In the first air guide grille component group 3b, a first gear 5 is provided on the motor shaft of the driving motor 4, and the first gear 5 is meshed with a rack 6 of one of the air guide grille components 3. Specifically, the first gear 5 can be fixedly sleeved on the motor shaft of the driving motor 4, and then the first gear 5 is meshed with the rack 6 on the active air guide grille component 3c, so that the driving motor 4 can indirectly drive the active air guide grille component 3c to rotate through the first gear 5.

[0067] It is understandable that, during actual assembly, considering factors such as the limitation of the internal installation space 26 or the requirements of the air outlet direction, the racks 6 of any two adjacent air guide grille components 3 in the first air guide grille component group 3b may not be directly meshed.

[0068] For example, Figure 8As shown, in some embodiments of the present invention, among any two adjacent air guide grille components 3 of the first air guide grille component group 3b, the racks 6 of at least one group of two adjacent air guide grille components 3 are meshed through the second gear 51, and the motor shaft of the drive motor 4 is connected to one of the air guide grille components 3. In this case, the rotation directions of the two air guide grille components 3 are the same. For the remaining multiple air guide grille components 3, for example, each air guide grille component 3 can be driven by a drive motor 4 alone, etc., and the present invention is not limited to this.

[0069] Specifically, refer to Figure 8 The first air guide grille component group 3b includes two air guide grille components 3 adjacent to each other in the up and down directions, and a second gear 51 is provided between the two air guide grille components 3. The second gear 51 is simultaneously engaged with the racks 6 of the two air guide grille components 3 so that the rotation directions of the two air guide grille components 3 are the same, which is beneficial to make the air outlet directions of the air outlets 111 corresponding to the two air guide grille components 3 the same.

[0070] Optionally, the second gear 51 can be rotatably mounted on the mounting plate 2 or the front panel 11 .

[0071] It should be noted that, in the absence of mutual contradiction, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification. For example, in one embodiment of the present invention, Fig. 9 As shown, among any two adjacent air guide grille components 3 of the first air guide grille component group 3b, the racks 6 of at least one group of two adjacent air guide grille components 3 are meshed together, and the racks 6 of at least one group of two adjacent air guide grille components 3 are meshed together through the second gear 51.

[0072] When there is one driving motor 4, multiple air guide grille components 3 are driven by one driving motor 4, so that all of the multiple air guide grille components 3 can be linked under the action of the driving motor 4. Therefore, the structure is simple, which is conducive to further reducing the cost and installation space of the driving motor 4.

[0073] In some embodiments of the present invention, each air guide grille component 3 includes an annular outer ring 32 and a plurality of grille bars 33 arranged in the outer ring 32. A rack 6 is provided on the outer peripheral wall of the outer ring 32. The rack 6 extends along the circumferential direction of the air guide grille component 3. The racks 6 of any two adjacent air guide grille components 3 are meshed together. The motor shaft of the drive motor 4 is connected to one of the air guide grille components 3. Therefore, among the multiple air guide grille components 3 that are linked by the meshing of the rack 6, the air guide grille component 3 connected to the drive motor 4 can act as an active air guide grille component 3c to drive the remaining air guide grille components 3 (i.e., the driven air guide grille components 3d) to rotate. Therefore, the structure is simple and easy to implement.

[0074] It is understandable that the air guide grille component 3 may also be in other shapes, which should be selected according to actual needs, and the present invention does not limit this.

[0075] In practical applications, the driving motor 4 can directly drive the active air guide grille component 3c to rotate. For example, in some embodiments of the present invention, a pivot hole is provided at the central axis of the active air guide grille component 3c, and the motor shaft of the driving motor 4 is plugged into the pivot hole, so that the driving motor 4 can directly drive the air guide grille component 3 to rotate.

[0076] Alternatively, the driving motor 4 may also indirectly drive the air guide grille component 3 to rotate. For example, in some embodiments of the present invention, a first gear 5 is provided on the motor shaft of the driving motor 4, and the first gear 5 is meshed with a rack 6 of one of the air guide grille components 3. Specifically, the first gear 5 may be fixedly sleeved on the motor shaft of the driving motor 4, and then the first gear 5 is meshed with the rack 6 on the active air guide grille component 3c, so that the driving motor 4 can indirectly drive the active air guide grille component 3c to rotate through the first gear 5, and then drive the remaining air guide grille components 3 to rotate.

[0077] It is understandable that, in actual assembly, considering the limitation of the internal installation space 26 or the requirements of the air outlet direction and many other factors, the racks 6 of any two adjacent air guide grille components 3 may not be directly meshed. For example, in some embodiments of the present invention, in any two adjacent air guide grille components 3, the racks 6 of at least one group of two adjacent air guide grille components 3 are meshed through the second gear 51, and the motor shaft of the drive motor 4 is connected to one of the air guide grille components 3. In this case, the rotation directions of the two air guide grille components 3 are the same. For the remaining multiple air guide grille components 3, for example, each air guide grille component 3 may be driven by a drive motor 4 alone, etc., and the present invention does not limit this.

[0078] It should be noted that, in the absence of mutual contradiction, those skilled in the art may combine and combine the different embodiments or examples and the features of the different embodiments or examples described in this specification. For example, in one embodiment of the present invention, in any two adjacent air guide grille components 3, at least one set of racks 6 of two adjacent air guide grille components 3 are meshed, and at least one set of racks 6 of two adjacent air guide grille components 3 are meshed through the second gear 51.

[0079] In some examples, the racks 6 of every two adjacent air guide grille components 3 are meshed with each other through the second gear 51. This is simple and convenient.

[0080] In some embodiments of the present invention, Fig.10 As shown, the drive motor 4 is mounted on the mounting plate 2 where the vent 21 corresponding to the air guide grille component 3 directly connected to the drive motor 4 is located. That is to say, the drive motor 4 is used to drive which air guide grille component 3 to rotate, and the drive motor 4 is mounted on the mounting plate 2 where the vent 21 corresponding to the air guide grille component 3 is located and is arranged adjacent to the vent 21.

[0081] Since the space inside the casing 1 is usually small and the power to drive the air guide grille component 3 to rotate does not need to be too large, in order to improve space utilization and make the structure of the device more compact, the drive motor 4 here can use a stepper motor, which is small in size, low in cost, and easy to control.

[0082] Alternatively, if Fig.10 and Fig.11 As shown, the air conditioner 100 also includes a motor cover 7, the number of the motor covers 7 is the same as the number of the drive motors 4 and corresponds one to one, each motor cover 7 is mounted on the rear surface of the corresponding mounting plate 2 and defines a mounting space 26 with the mounting plate 2, the first gear 5 and the drive motor 4 are located in the mounting space 26, and a portion of the first gear 5 extends from the mounting space 26 to cooperate with the rack 6 of the corresponding air guide grille component 3. This design allows the mounting space 26 to protect the drive motor 4 and the first gear 5, thereby extending the service life of the device.

[0083] During specific assembly, the first gear 5 can be fixedly sleeved on the output shaft of the driving motor 4 first, and then the driving motor 4 is installed on the motor cover 7, and then the motor cover 7 is installed on the mounting plate 2, so as to facilitate installation.

[0084] In practical applications, the motor cover 7 and the mounting plate 2 can be connected by connecting parts such as screws or by snap fasteners. The specific method should be flexibly selected according to actual production and assembly conditions, and the present invention does not impose any limitation on this.

[0085] In some embodiments of the present invention, Fig.10 and Fig.11 As shown, a forward-recessed receiving groove 25 is provided on a portion of the inner surface of the installation space 26 located on the installation plate 2, and a side of the receiving groove 25 adjacent to the corresponding ventilation opening 21 is open to define an escape opening 251, and the first gear 5 is located in the receiving groove 25 and a portion of the first gear 5 extends out of the installation space 26 through the escape opening 251, thereby making the structure more compact.

[0086] Specifically, for example, refer to Fig.10 and Fig.11 The receiving groove 25 is roughly cylindrical and is located above the vent 21. An escape opening 251 is provided on the lower side of the receiving groove 25. Thus, when the first gear 5 is disposed in the receiving groove 25, a portion of the first gear 5 can pass through the escape opening 251 and extend out of the installation space 26 to engage with the rack 6 to drive the air guide grille component 3 to rotate.

[0087] In practical applications, for the air guide grille component 3, the connection form of the grille bars 33 and the inner ring 31 and the outer ring 32 is not limited. For example, the grille bars 33 and the inner ring 31 and the outer ring 32 can be formed into one piece by injection molding, thereby facilitating processing.

[0088] Alternatively, in some embodiments of the present invention, Fig.13 and Fig.14 As shown, each grille bar 33 is rotatably disposed between the inner ring 31 and the outer ring 32 , so that when the airflow flows through the outside of the air guide grille component 3 , the rotating grille bars 33 can also guide the airflow, thereby further enriching the air supply mode of the air conditioner 100 .

[0089] Specifically, for example, first pivot shafts are provided at both ends of the grille bar 33, and a first pivot hole is provided on the outer ring 32. The first pivot shaft cooperates with the first pivot hole, thereby enabling the grille bar 33 to rotate, and the structure is simple and easy to implement.

[0090] In practical applications, the grille bars 33 may be driven to rotate by a driving member, or may be manually rotated by a user, and the present invention does not limit this.

[0091] In some embodiments of the present invention, Fig.13 As shown, a plurality of grille bars 33 are arranged in parallel, and the plurality of grille bars 33 are connected by connecting rods 34 to achieve linkage, thereby the structure is simple.

[0092] Specifically, for example, a second pivot shaft is provided on the grille bar 33, and a plurality of second pivot holes are provided on the connecting rod 34. The plurality of second pivot holes are matched one-to-one with the second pivot shafts on the plurality of second grille bars 33, thereby realizing the linkage of the plurality of grille bars 33.

[0093] It is worth noting that, under the driving action of the connecting rod 34, all of the plurality of grille bars 33 may be linked together. Alternatively, only some of the grille bars 33 may be linked together. For example, in some embodiments, Fig.13 As shown, the multiple grille bars 33 are divided into multiple grille bar groups, each grille bar group includes a plurality of parallel grille bars 33, and the multiple grille bars 33 in each grille bar group are connected by connecting rods 34 to achieve linkage. The grille bars 33 of any two grille bar groups are not linked, so under the driving action of the connecting rods 34, only the linkage of all the grille bars 33 in the corresponding grille bar groups can be achieved. In this case, different grille bar groups can be swung to different angular positions, so that the guidance of the airflow can be different, thereby further enriching the air supply mode of the air conditioner 100.

[0094] In some embodiments of the present invention, Figure 5 As shown, the housing 1 further includes a rear panel 12, on which an air inlet 121 is provided, so that indoor air can enter the air conditioner 100 through the air inlet 121. In practical applications, the rear panel 12 can be connected to the front panel 11 through a snap-fit ​​structure and / or a connector such as screws, etc., for easy assembly.

[0095] Alternatively, if Figure 3 and Figure 5 As shown, the air conditioner 100 also includes a heat exchanger 8 and a plurality of fan assemblies 9, the fan assembly 9 is located on the rear side of the mounting plate 2, the plurality of fan assemblies 9 correspond one-to-one to the plurality of vents 21, the heat exchanger 8 is located between the fan assembly 9 and the air inlet 121, and a water receiving tray for collecting and discharging condensed water is provided at the bottom of the heat exchanger 8, whereby under the action of the fan assembly 9, the airflow entering the air conditioner 100 can exchange heat with the heat exchanger 8, and then flow to the vents 21 of the mounting plate 2 through the fan assembly 9, and finally be blown out from the air outlet 111 after being guided by the air guide grille component 3.

[0096] In actual applications, by adjusting the working conditions of different fan components 9 (such as the rotation speed, etc.), different air outlets 111 can blow out air flows with different air volumes or wind speeds, and thus different air outlets 111 can have different air outlet temperatures, so that the air conditioner 100 can achieve air supply with different temperatures, which is beneficial to improving the operating comfort of the air conditioner 100 and the softness of the wind feeling.

[0097] Specifically, the heat exchanger 8 is in the shape of a flat plate. Compared with the heat exchanger 8 with an arc-shaped structure in the related art, this structural form can make the air intake of the heat exchanger 8 more uniform, thereby improving the heat exchange efficiency.

[0098] like Fig.12As shown, the fan assembly 9 includes a fan 91 and a stationary blade bracket 92. The fan 91 is an axial flow fan 91. The stationary blade bracket 92 is located at the air outlet end of the fan 91. The stationary blade bracket 92 is provided with stationary blades, so as to guide the airflow blown out by the axial flow fan 91. During actual assembly, the stationary blade bracket 92 is located at the rear side of the mounting plate 2, and multiple stationary blade brackets 92 correspond to multiple vents 21 one by one.

[0099] In some embodiments of the present invention, Figure 6 and Fig.12 As shown, a first stop portion 35 is provided in the inner ring 31, and the first stop portion 35 is arranged offset from the center of the inner ring 31. A second stop portion 93 is provided on the stationary blade bracket 92, and the air guide grille component 3 has a stop position. When the air guide grille component 3 rotates to the stop position along the first direction, the first stop portion 35 cooperates with the second stop portion 93 to prevent the air guide grille component 3 from further rotating along the first direction.

[0100] Specifically, for example, refer to Figure 6 and Fig.12 , a first stopper 35 is provided on the inner ring 31 of each air guide grille component 3, the first stopper 35 is connected to the inner peripheral wall of the inner ring 31, and the first stopper 35 extends backward, and a second stopper 93 is provided on the stationary blade support 92, the second stopper 93 extends forward, and the second stopper 93 and the first stopper 35 have a rotation circumferential trajectory that intersects, so that when the first stopper 35 rotates along the first direction with the air guide grille component 3, there is a situation that the first stopper 35 will abut against the second stopper 93 to prevent the air guide grille component 3 from further rotating in the first direction, and the air guide grille component 3 is in a stopped position in this case. Specifically, the first direction can be a clockwise direction or a counterclockwise direction, and the present invention is not limited to this.

[0101] In actual applications, the abutment between the first stop portion 35 and the second stop portion 93 can be regarded as a feedback signal, which can be used in the control process of the controller of the air conditioner 100 driving the air guide grille component 3 to rotate through the driving motor 4, and used as the judgment origin of the program control. This is beneficial to ensure that the angle of the air guide grille component 3 when it is reset can always remain consistent. In addition, this setting is also beneficial to simplify the entire control process and reduce the control cost.

[0102] In some embodiments of the present invention, Figure 4 and Fig.11 As shown, a flange 23 extending forward is provided on the outer peripheral wall of the mounting plate 2, and the free end of the flange 23 abuts against the rear surface of the front panel 11 so that the mounting plate 2 and the front panel 11 define a receiving space 22, thereby having a simple structure and being easy to implement.

[0103] Specifically, for example, refer to Figure 4 and Fig.11 The upper and lower end surfaces of the mounting plate 2 are both provided with flanges 23, which are perpendicular to the mounting plate 2 and extend forward, the rear end of the flange 23 is connected to the mounting plate 2, and the front end of the flange 23 abuts against the rear surface of the front panel 11, thereby defining an accommodation space 22 between the mounting plate 2 and the front panel 11, and the structure is simple and easy to implement. The flanges 23 can improve the structural strength of the mounting plate 2 and prevent the mounting plate 2 from being damaged, and can also shield and protect the air guide grille component 3 to a certain extent.

[0104] In some embodiments of the present invention, the length of the accommodating space 22 in the front-to-back direction is greater than the thickness of the air guide grille component 3, so that when the air guide grille component 3 is located behind the accommodating space 22, there is a gap between the air guide grille component 3 and the mounting plate 2 and / or the front panel 11, which is conducive to the smooth rotation of the air guide grille component 3.

[0105] In some embodiments of the present invention, as 4 and Fig.10 As shown, a mounting column 14 is provided on the rear surface of the front panel 11, and the mounting column 14 includes a first connecting column 141 and a second connecting column 142. One end of the first connecting column 141 (i.e., the front end of the first connecting column 141) is connected to the rear surface of the front panel 11 and the first connecting column 141 extends backward, and one end of the second connecting column 142 (i.e., the front end of the second connecting column 142) is connected to the rear end surface of the first connecting column 141 and the second connecting column 142 extends backward. The cross-sectional area of ​​the second connecting column 142 is smaller than the cross-sectional area of ​​the first connecting column 141. A mounting hole 24 is provided on the mounting plate 2, and the mounting hole 24 is sleeved on the outer peripheral wall of the second connecting column 142. The rear end surface of the first connecting column 141 excluding the portion connected to the second connecting column 142 is suitable for limiting the mounting plate 2 to prevent the mounting plate 2 from contacting the front panel 11. Therefore, the structure is simple and the installation is convenient.

[0106] Specifically, during assembly, since the cross-sectional area of ​​the second connecting column 142 is smaller than the cross-sectional area of ​​the first connecting column 141, the first connecting column 141 and the second connecting column 142 can roughly form a step structure at the connection. When the mounting plate 2 is sleeved on the second connecting column 142 through the mounting hole 24, the step structure can limit the mounting plate 2 so that the mounting plate 2 abuts against the first connecting column 141, thereby preventing the mounting plate 2 from contacting the front panel 11 and affecting the installation of the air guide grille component 3.

[0107] Optionally, refer to Figure 4 The second connecting column 142 is coaxially arranged with the first connecting column 141 , and the outer diameter of the second connecting column 142 is smaller than the outer diameter of the first connecting column 141 , thereby simplifying the structure and facilitating processing.

[0108] It is understandable that the mounting plate 2 and the front panel 11 may not be connected except through the above-mentioned structure. For example, the mounting plate 2 may be connected to other components of the air conditioner 100 (such as the stationary blade bracket 92 of the fan assembly 9 or the left and right side walls of the housing 1).
