[0039] First embodiment

[0040] See also Figure 1 and Figure 2 The present embodiment provides an air duct self-cleaning mechanism 100, which can realize the function of automatically cleaning the air duct 190 and the wind wheel, and has good cleaning effect and stable driving.

[0041] The air duct self-cleaning mechanism 100 provided in this embodiment includes a cleaning brush rod 110, a base body 130, a driving assembly 150 and a driving outer box 170. The base body 130 is provided with an air duct 190, the cleaning brush rod 110 is arranged in the air duct 190, the driving outer box 170 is arranged on the base body 130, the driving assembly 150 is movably arranged in the driving outer box 170, and a transmission member 180 is fixedly arranged in the driving outer box 170, the driving assembly 150 is transmission-connected to the transmission member 180, the driving assembly 150 is used to drive itself to move, and moves in the driving outer box 170 driven by the transmission member 180, the cleaning brush rod 110 is connected to the driving assembly 150, and is used to move along the air duct 190 driven by the driving assembly 150.

[0042] In this embodiment, the base 130 is arranged inside the wall-mounted air conditioner, and includes a bottom shell 131 and side panels 133 arranged on both sides of the bottom shell 131, and the inner side surface of the bottom shell 131 and the inner side surfaces of the two side panels 133 are jointly arranged to form an air duct 190, and the driving outer box 170 is detachably arranged on the outer side of the side panels 133. A wind wheel is also installed in the air duct 190, and the two ends of the wind wheel are rotatably installed on the two side panels 133, respectively, and there is a cleaning gap between the wind wheel and the bottom shell 131. The cleaning brush rod 110 moves in the cleaning gap under the drive of the driving assembly 150 and fits on the surface of the bottom shell 131, thereby cleaning the air duct 190.

[0043] It should be noted that, in this embodiment, the cleaning brush rod 110 moves along the width direction of the air duct 190 driven by the driving assembly 150, wherein the width direction of the air duct 190 refers to a direction perpendicular to the axial direction of the wind wheel.

[0044] The air duct self-cleaning mechanism 100 provided in this embodiment is achieved by setting the cleaning brush rod 110 in the air duct 190. At the same time, the driving component 150 can drive itself to move, and move in the driving outer box 170 driven by the transmission member 180, and drive the cleaning brush rod 110 to move along the air duct 190, thereby achieving cleaning of the air duct 190.

[0045] See also Figure 3 and Figure 4 The driving assembly 150 includes a driving member 151 and a driving inner box 153. A limiting slide groove 171 is provided in the driving outer box 170. The driving member 151 is provided in the driving inner box 153 and is in transmission connection with the transmission member 180. The driving inner box 153 is slidably provided on the limiting slide groove 171 and is used to move along the limiting slide groove 171 under the drive of the driving member 151. The cleaning brush rod 110 is in transmission connection with the driving inner box 153 and is used to move along the air duct 190 under the drive of the driving inner box 153. By providing the limiting slide groove 171, the movement trajectory of the driving inner box 153 is limited, the stability of the driving inner box 153 during the movement is ensured, and then the driving stability of the cleaning brush rod 110 is ensured, and the cleaning effect is ensured.

[0046] In this embodiment, a clearance opening 173 is also provided on the driving outer box 170. The end of the cleaning brush rod 110 passes through the clearance opening 173 and is connected to the driving inner box 153. By providing the clearance opening 173, the driving outer box 170 is prevented from interfering with the movement of the cleaning brush rod 110.

[0047] In this embodiment, the inner side surface of the bottom shell 131 is an arc-shaped surface, and the edge of the bottom shell 131 is an arc-shaped surface, and the limiting slide groove 171 is also an arc-shaped surface, and the curvature of the limiting slide groove 171 is the same as the curvature of the edge of the bottom shell 131, so that the driving inner box 153 can drive the cleaning brush rod 110 to move along the width direction of the air duct 190 during the sliding process along the limiting slide groove 171. Of course, in other preferred embodiments, the inner side surface of the bottom shell 131 can also be a plane, so that the edge of the bottom shell 131 is a straight line, the limiting slide groove 171 is also a straight line, and the limiting slide groove 171 is parallel to the edge of the bottom shell 131.

[0048] The driving member 151 includes a driving gear 151a and a driving motor 151b. The driving gear 151a is rotatably arranged in the driving inner box 153. The driving motor 151b is accommodated in the driving inner box 153 and is in transmission connection with the driving gear 151a, so as to drive the driving gear 151a to rotate. The transmission member 180 includes a transmission rack 181, which is fixedly arranged on the side wall of the driving outer box 170, and the extension direction of the transmission rack 181 is parallel to or has the same arc as the extension direction of the limiting slide groove 171, and the driving gear 151a is meshed with the transmission rack 181. Through the meshing between the driving gear 151a and the transmission rack 181, the driving gear 151a can be driven to move itself under the drive of the transmission rack 181, and the transmission mode of the gear rack also ensures the stability of the transmission and avoids the occurrence of slipping or jamming.

[0049] In this embodiment, the transmission rack 181 is integrally arranged on the side wall of the driving outer box 170, and the extension direction of the transmission rack 181 is arc-shaped, and the curvature of the transmission rack 181 is the same as the curvature of the limiting slide groove 171, so that when the driving gear 151a moves and rolls along the transmission rack 181, it can drive the driving inner box 153 to slide along the limiting slide groove 171. In other preferred embodiments of the present invention, when the limiting slide groove 171 is linear, the transmission rack 181 is also linear and parallel to the limiting slide groove 171.

[0050] The driving inner box 153 includes an inner box body 153a and an inner box cover 153b. The inner box body 153a is slidably arranged on the limiting slide groove 171. The inner box cover 153b is covered on the inner box body 153a and forms a driving inner cavity. A transmission opening 153c is provided on the side of the driving inner cavity close to the transmission member 180. The driving member 151 is arranged in the driving inner cavity and partially extends out of the transmission opening 153c. The transmission member 180 is connected to the driving member 151 extending out of the transmission opening 153c. Specifically, the driving gear 151a partially extends out of the transmission opening 153c and meshes with the transmission rack 181. Through the inner box body 153a and the inner box cover 153b that are separately arranged, the driving member 151 can be loaded and then the inner box cover 153b can be covered during assembly, which is convenient for assembly and improves assembly efficiency.

[0051] In this embodiment, the width of the transmission opening 153c is greater than the thickness of the driving gear 151a, so that the driving gear 151a can partially extend out of the transmission opening 153c and engage with the transmission rack 181. Specifically, the length of the driving gear 151a extending out of the transmission opening 153c is greater than or equal to the tooth height of the driving gear 151a, thereby avoiding contact between the driving inner box 153 and the transmission rack 181.

[0052] In this embodiment, one of the inner box body 153a and the inner box cover 153b is provided with a driving buckle 153d, and the other is provided with a driving clamping block 153e, and the driving buckle 153d is clamped on the driving clamping block 153e. Specifically, the inner box body 153a is provided with a driving buckle 153d, and the inner box cover 153b is provided with a driving clamping block 153e, and the driving buckle 153d is clamped on the driving clamping block 153e, so that the inner box cover 153b can be clamped with the inner box body 153a to ensure the fixing effect. When disassembling, only the driving buckle 153d needs to be pulled to release the clamping effect with the driving clamping block 153e, so as to remove the inner box cover 153b. The assembly between the inner box body 153a and the inner box cover 153b is realized by clamping the driving buckle 153d on the driving clamping block 153e, which is convenient for disassembly and assembly and has a good fixing effect.

[0053] In this embodiment, the inner driving box 153 is provided with a guide post 155, which is slidably disposed in the limiting slide groove 171. Specifically, the guide post 155 is a cylindrical structure, and the guide post 155 is disposed on the inner box cover 153b and the outer box cover 177, and the limiting slide grooves 171 are disposed on the two opposite bottom walls of the outer driving box 170, and the guide posts 155 on the inner box cover 153b and the outer box cover 177 extend into the two limiting slide grooves 171 respectively, thereby realizing the limiting of the inner driving box 153. The inner driving box 153 is guided and limited by the guide post 155 being slidably disposed in the limiting slide groove 171, which further ensures the movement stability of the inner driving box 153.

[0054] The driving outer box 170 includes an outer box body 175 and an outer box cover 177. The outer box body 175 is detachably arranged on the seat body 130, and the outer box cover 177 is covered on the outer box body 175. The transmission member 180 is fixedly arranged on the side wall of the outer box body 175, and at least one of the outer box body 175 and the outer box cover 177 is provided with a limiting slide groove 171. Specifically, the outer box body 175 and the outer box cover 177 are both provided with a limiting slide groove 171. Through the outer box body 175 and the outer box cover 177 that are separately arranged, the driving inner box 153 can be first assembled in the limiting slide groove 171 on the outer box body 175 or the outer box cover 177 during assembly, and then the outer box cover 177 is covered on the outer box body 175, which is very convenient and improves the assembly efficiency.

[0055] In other preferred embodiments of the present invention, the inner box cover 153b is provided with a guide post 155, and the outer box cover 177 is provided with a limit slot 171, so that the guide post 155 is slidably accommodated in the corresponding limit slot 171. Alternatively, the inner box body 153a is provided with a guide post 155, and the outer box body 175 is provided with a limit slot 171, so that the guide post 155 is slidably accommodated in the corresponding limit slot 171.

[0056] In this embodiment, one of the outer box body 175 and the outer box cover 177 is provided with a transmission buckle 175a, and the other is provided with a transmission clamping block 175b, and the transmission buckle 175a is clamped on the transmission clamping block 175b. Specifically, the outer box body 175 is provided with a transmission buckle 175a, and the outer box cover 177 is provided with a transmission clamping block 175b, and the transmission buckle 175a is clamped on the transmission clamping block 175b, so that the outer box cover 177 is clamped on the outer box body 175. The assembly between the outer box body 175 and the outer box cover 177 is achieved by clamping the transmission buckle 175a on the transmission clamping block 175b, which is convenient for disassembly and assembly and has a good fixing effect.

[0057] See also Figure 5 and Figure 6 The side plate 133 is provided with a guide groove 135 extending along the edge of the bottom shell 131, and the extension direction of the guide groove 135 is parallel to or has the same arc as the extension direction of the limiting slide groove 171. The driving outer box 170 is arranged on the side plate 133, and the end of the cleaning brush rod 110 is penetrated through the guide groove 135 and connected to the driving inner box 153, so as to move along the extension direction of the guide groove 135 under the drive of the driving inner box 153. By providing the guide groove 135 on the side plate 133, the driving inner box 153 drives the cleaning brush rod 110 to move along the guide groove 135, thereby achieving the guidance and limitation of the cleaning brush rod 110, and further ensuring the stability of the movement of the cleaning brush rod 110.

[0058] In this embodiment, the guide groove 135 is arc-shaped, and its curvature is the same as that of the limiting slide groove 171. In other preferred embodiments of the present invention, when the limiting slide groove 171 is linear, the guide groove 135 is also linear and parallel to the limiting slide groove 171.

[0059] In this embodiment, a receiving groove 139 for accommodating the cleaning brush rod 110 is further provided on the bottom shell 131, and the two ends of the receiving groove 139 extend to the two side plates 133 respectively. The side plates 133 are further provided with an escape groove 137 connected to the guide groove 135, and the escape groove 137 is arranged opposite to the receiving groove 139. The driving assembly 150 is also used to drive the cleaning brush rod 110 to move along the escape groove 137, so that the cleaning brush rod 110 enters or leaves the receiving groove 139. By providing the receiving groove 139 on the bottom shell 131, the cleaning brush rod 110 can be stored in the receiving groove 139 when not cleaning, thereby preventing the cleaning brush rod 110 from staying in the air duct 190 and affecting the gas flow in the air duct 190.

[0060] It should be noted that in this embodiment, the width of the avoidance groove 137 is the same as the width of the guide groove 135. Driven by the driving inner box 153, the cleaning brush rod 110 can slide from the guide groove 135 to the avoidance groove 137, and can also slide from the avoidance groove 137 to the guide groove 135, thereby realizing the function of the cleaning brush rod 110 entering or leaving the receiving groove 139.

[0061] In this embodiment, the driving inner box 153 is further provided with an inclined guide hole 153f, and the end of the cleaning brush rod 110 is slidably inserted into the inclined guide hole 153f, and is used to slide along the inclined guide hole 153f under the drive of the driving assembly 150, so that the cleaning brush rod 110 moves along the avoidance groove 137. By providing the inclined guide hole 153f in the driving inner box 153, the driving inner box 153 can drive the cleaning brush rod 110 to enter or leave the receiving groove 139 under the driving action of the driving member 151, avoiding the need for an additional driving mechanism to achieve this function, and simplifying the structure.

[0062] It should be noted that, in this embodiment, the extending direction of the inclined guide hole 153f is arranged at an acute angle with the moving direction of the driving inner box 153, and the inclined direction of the inclined guide hole 153f is opposite to the inclined direction of the avoidance groove 137, and is opposite to the moving direction of the cleaning brush rod 110 when leaving the receiving groove 139. Specifically, when the cleaning brush rod 110 leaves the receiving groove 139, under the supporting action of the lower side of the inclined guide hole 153f, the cleaning brush rod 110 is subjected to a relatively upward supporting force, which can drive the cleaning brush rod 110 to move upward. At the same time, since the inclined guide hole 153f is arranged obliquely, in the process of driving the cleaning brush rod 110 to move upward, the cleaning brush rod 110 moves along the avoidance groove 137, thereby leaving the receiving groove 139. When the cleaning brush rod 110 enters the accommodating groove 139, under the resistance or gravity of the upper side of the inclined guide hole 153f, the cleaning brush rod 110 is subjected to downward gravity or resistance. At the same time, due to the inclined setting of the inclined guide hole 153f, the cleaning brush rod 110 can move downward while moving along the avoidance groove 137, thereby entering the accommodating groove 139.

[0063] In summary, the present embodiment provides a self-cleaning mechanism 100 for the air duct, and its driving process is as follows: when cleaning is required, the driving motor 151b is started, and the driving motor 151b drives the driving gear 151a to rotate. Under the meshing action of the driving gear 151a and the transmission rack 181, the driving inner box 153 is driven to slide along the limiting slide groove 171, and at the same time, the driving inner box 153 drives the cleaning brush rod 110 to move along the avoidance groove 137 through the inclined guide hole 153f, and drives the cleaning brush rod 110 to leave the receiving groove 139. After leaving the receiving groove 139, the driving inner box 153 continues to drive the cleaning brush rod 110 to move upward along the guide groove 135 to achieve cleaning of the air duct 190. When the cleaning brush rod 110 moves to the upper limit position, the driving motor 151b is stopped. Due to the narrowing of the cleaning gap, the cleaning brush rod 110 can contact the wind wheel. At this time, the wind wheel is slowly started to achieve cleaning of the wind wheel.
