DETAILED DESCRIPTION

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] First embodiment

[0045] See also Figures 1 to 3 The present embodiment provides an air conditioner self-cleaning mechanism 100, which can realize automatic cleaning of the air duct 180 and the wind wheel, and has a good cleaning effect.

[0046] The air conditioner self-cleaning mechanism 100 provided in this embodiment includes a cleaning brush roller 110, a base 130, a drive box 150 and a drive assembly 170. The base 130 has an air duct 180. The cleaning brush roller 110 is arranged in the air duct 180. The drive box 150 is arranged on the base 130. The drive assembly 170 is accommodated in the drive box 150 and is transmission-connected to the cleaning brush roller 110. A transmission member 190 is arranged in the drive box 150. The transmission member 190 is transmission-connected to the drive assembly 170. The drive assembly 170 is used to move in the drive box 150 driven by the transmission member 190. The cleaning brush roller 110 is used to rotate driven by the drive assembly 170 and move along the air duct 180.

[0047] In this embodiment, the air conditioning self-cleaning mechanism 100 is arranged in the air conditioning shell of the wall-mounted air conditioner, and a wind wheel is rotatably installed in the air duct 180. The cleaning brush roller 110 is driven by the driving component 170 to realize self-rotation and movement along the width direction of the air duct 180, wherein the width direction of the air duct 180 refers to the direction in the air duct 180 perpendicular to the axial direction of the wind wheel.

[0048] In this embodiment, the driving assembly 170 is connected to the transmission member 190 in a transmission manner, so that the driving assembly 170 can drive itself to move in the driving box 150 through the transmission effect with the transmission member 190 when driving, and the driving assembly 170 set on the base 130 drives the cleaning brush roller 110 to rotate, and at the same time moves along the air duct 180, so as to realize the function of cleaning the air duct 180 while rotating, and the air duct 180 can be cleaned without disassembling it. Compared with the prior art, the air conditioner self-cleaning mechanism 100 provided by the present invention does not need to disassemble the air duct 180 for cleaning, and can realize automatic cleaning of the air duct 180 with good cleaning effect.

[0049] The base 130 includes a bottom shell 131 and side panels 133 disposed on both sides of the bottom shell 131 . The inner side surface of the bottom shell 131 and the inner side surfaces of the two side panels 133 surround and form an air duct 180 . The drive box 150 is disposed on the side panels 133 . Specifically, the drive box 150 is detachably arranged on the outer side surface of the side plate 133, and the two ends of the wind wheel are rotatably assembled on the two side plates 133 respectively. The inner side surface of the bottom shell 131 constitutes the bottom wall of the air duct 180, and the inner side surfaces of the two side plates 133 constitute the side walls of the air duct 180. In the present embodiment, there is a wind sweeping gap between the bottom shell 131 and the wind wheel. The airflow generated by the wind wheel passes through the wind sweeping gap and is blown out from the air outlet to achieve air outlet. The cleaning brush roller 110 is accommodated in the wind sweeping gap during cleaning and moves along the width direction of the air duct 180 in the wind sweeping gap, thereby avoiding contact with the wind wheel all the time. Since the lower width of the wind sweeping gap is greater than the upper width, when the cleaning brush roller 110 moves to the top along the air duct 180, it can contact the wind wheel at a certain point. At this time, the wind wheel is started at a low speed to achieve cleaning of the wind wheel.

[0050] In this embodiment, the inner side surface of the bottom shell 131 is an arc-shaped surface, so that the trajectory of the cleaning brush roller 110 when moving along the air duct 180 is an arc-shaped shape. Of course, in other preferred embodiments, the inner side surface of the bottom shell 131 can also be a plane, so that the trajectory of the cleaning brush roller 110 when moving along the air duct 180 is a straight line shape.

[0051] See also Figures 4 to 7The driving assembly 170 includes a first driving member 171, a second driving member 173 and a transmission box 175. A driving groove 151 is provided in the driving box 150. The transmission box 175 is slidably arranged on the driving groove 151. The first driving member 171 and the second driving member 173 are both arranged in the transmission box 175. The first driving member 171 is connected to the transmission member 190 for driving the transmission box 175 to move along the driving groove. A clearance hole 153 is opened on the driving box 150. The cleaning brush roller 110 is inserted into the clearance hole 153 and is connected to the second driving member 173 for driving. The second driving member 173 is used to drive the cleaning brush roller 110 to rotate. The first driving member 171 drives the transmission box 175 to move along the driving groove 151, and drives the second driving member 173 to move along the driving groove 151, and the second driving member 173 drives the cleaning brush roller 110 to rotate, thereby realizing the function of the cleaning brush roller 110 rotating while moving along the air duct 180, and by setting the driving groove 151, the driving process of the driving component 170 is made more stable.

[0052] In this embodiment, the driving slide groove 151 is arc-shaped, and its curvature is the same as the edge curvature of the bottom shell 131, so that the cleaning brush roller 110 can be driven to move along the inner side of the bottom shell 131. Of course, in other preferred embodiments, when the inner side of the bottom shell 131 is a plane, the driving slide groove 151 is linear.

[0053] In this embodiment, the transmission box 175 is slidably accommodated in the drive box 150. The transmission box 175 as a whole can move along the drive groove 151 under the drive of the first drive member 171, thereby driving the cleaning brush roller 110 to move along the air duct 180. While the first drive member 171 is driving, the second drive member 173 can drive the cleaning brush roller 110 to rotate. The first drive member 171 and the second drive member 173 are driven independently of each other, so that the cleaning brush roller 110 can rotate while moving along the width direction of the air duct 180.

[0054] It should be noted that in this embodiment, the cleaning brush roller 110 is driven to rotate by the second driving member 173. When the cleaning brush roller 110 cleans the air duct 180, dust in the air duct 180 can be prevented from accumulating on one side of the cleaning brush roller 110, thereby further ensuring a good cleaning effect.

[0055] In this embodiment, the transmission member 190 includes a transmission rack 191 disposed on the side wall of the driving box 150, and the extension direction of the transmission rack 191 is parallel to or has the same curvature as the extension direction of the driving slide 151. Specifically, the transmission rack 191 is arc-shaped, and its curvature is the same as that of the driving slide 151, so that the transmission box 175 can be driven to slide in the driving slide 151. Of course, in other preferred embodiments, when the driving slide 151 is linear, the transmission rack 191 is parallel to the driving slide 151.

[0056] The transmission box 175 is rotatably provided with a driving gear 177, and the first driving member 171 is in transmission connection with the driving gear 177, so as to drive the driving gear 177 to rotate, and the driving gear 177 is meshed with the transmission rack 191. By providing the transmission rack 191, and the first driving member 171 is in transmission connection with the driving gear 177, and the driving gear 177 is meshed with the transmission rack 191, during actual operation, the first driving member 171 drives the driving gear 177 to rotate, and due to the meshing action of the transmission rack 191, the driving gear 177 and the first driving member 171 can move in the driving box 150, and the transmission is stable, which can avoid the situation of slipping or transmission failure.

[0057] In this embodiment, the first driving member 171 and the second driving member 173 are both driving motors. The output shaft of the first driving member 171 is passed through the driving gear 177, thereby driving the driving gear 177 to rotate. The output shaft of the second driving member 173 is connected to the cleaning brush roller 110, thereby directly driving the cleaning brush roller 110 to rotate.

[0058] It should be noted that the transmission rack 191 is integrally arranged on the inner wall of the driving box 150. During the actual movement process, the transmission rack 191 remains fixed, and the driving gear 177 rotates under the drive of the first driving member 171, thereby applying a driving force to the transmission rack 191. Under the reverse action of the force, the driving gear 177 can be driven to move along the transmission rack 191, thereby driving the entire transmission box 175 to move along the driving groove 151.

[0059] In this embodiment, a guide post 179 is provided on the transmission box 175, and the guide post 179 is slidably disposed in the driving chute 151, so that the transmission box 175 can move along the driving chute 151. By providing the guide post 179 and sliding the guide post 179 in the driving chute 151, the transmission box 175 is more stable when moving along the driving chute 151, thereby ensuring the driving stability of the cleaning brush roller 110.

[0060] The transmission box 175 includes a bearing box body 175a and a limit box cover 175b. The bearing box body 175a is slidably disposed on the driving slide groove 151. The first driving member 171 and the second driving member 173 are both disposed on the bearing box body 175a. The limit box cover 175b is detachably covered on the bearing box body 175a. The transmission box 175 is formed by the separate limit box body and the limit box cover 175b. When assembling, the first driving member 171 and the second driving member 173 can be first installed on the bearing box body 175a, and then the limit box cover 175b can be covered, which is convenient for assembly.

[0061] In this embodiment, one of the carrying box body 175a and the limiting box cover 175b is provided with a first buckle 175c, and the other is provided with a first clamping block 175d, and the first buckle 175c is clamped on the first clamping block 175d. Specifically, the carrying box body 175a is provided with a first buckle 175c, and the limiting box cover 175b is provided with a first clamping block 175d, and the first buckle 175c is clamped on the first clamping block 175d. The detachable connection between the carrying box body 175a and the limiting box cover 175b is achieved by the structure of the buckle and the clamping block, so as to facilitate disassembly while ensuring the fixing effect. Of course, the detachable connection between the carrying box body 175a and the limiting box cover 175b can also be achieved by other structures, such as by bolts or pins.

[0062] The drive box 150 includes a drive box body 155 and a drive box cover 157. The drive box body 155 is arranged on the base 130, the transmission member 190 is arranged on the side wall of the drive box body 155, the drive box cover 157 is detachably covered on the drive box body 155, and at least one of the drive box cover 157 and the drive box body 155 is provided with a drive slide groove 151. Through the drive box body 155 and the drive box cover 157 that are separately arranged, during assembly, the transmission box 175 can be first slidably assembled on the drive box body 155, and then the drive box cover 157 is covered, which is convenient for assembly.

[0063] In the present embodiment, one of the drive box body 155 and the drive box cover 157 is provided with a second buckle 155a, and the other is provided with a second clamping block 157a, and the second buckle 155a is clamped on the second clamping block 157a. Specifically, the drive box body 155 is provided with a second buckle 155a, and the drive box cover 157 is provided with a second clamping block 157a, and the second buckle 155a is clamped on the second clamping block 157a. The cover between the drive box body 155 and the drive box cover 157 is achieved by the structure of the buckle and the clamping block, which can ensure the fixing effect and facilitate disassembly. Of course, the drive box body 155 and the limit box cover 175b can also be detachably connected by other structures, such as by bolts or pins.

[0064] See also Figures 8 to 10 , a first guide groove 135 extending along the edge of the bottom shell 131 is provided on the side plate 133, and the extension direction of the driving slide groove 151 is parallel to or has the same arc as the extension direction of the first guide groove 135. Specifically, the first guide groove 135 is arc-shaped, and its arc is the same as that of the driving slide groove 151. Of course, in other preferred embodiments, when the driving slide groove 151 is linear, the first guide groove 135 is also linear, so that the cleaning brush roller 110 moves in a linear direction.

[0065] The end of the cleaning brush roller 110 is inserted into the first guide groove 135 and is in transmission connection with the second driving member 173. The cleaning brush roller 110 is used to move along the first guide groove 135 under the drive of the first driving member 171. By providing the first guide groove 135 on the side plate 133, and the extension direction of the first guide groove 135 has the same arc as the extension direction of the driving slide groove 151, the first guide groove 135 can further realize the limiting guiding function of the cleaning brush roller 110, and further ensure the driving stability of the cleaning brush roller 110.

[0066] In this embodiment, a brush roller accommodating groove 139 is further provided on the bottom shell 131, and both ends of the brush roller accommodating groove 139 extend to the two side plates 133 respectively. A second guide groove 137 communicating with the first guide groove 135 is further provided on the side plate 133, and the second guide groove 137 is arranged opposite to the brush roller accommodating groove 139. The cleaning brush roller 110 is also used to move along the second guide groove 137 driven by the transmission box 175 to enter or leave the brush roller accommodating groove 139. By providing the brush roller accommodating groove 139 on the bottom shell 131, the cleaning brush roller 110 can be accommodated in the brush roller accommodating groove 139 when it is not being cleaned, thereby preventing the cleaning brush roller 110 from being placed in the air duct 180 to affect the flow direction of the gas in the air duct 180, thereby ensuring the air outlet effect.

[0067] It should be noted that the width of the second guide groove 137 is the same as that of the first guide groove 135, and the two have a smooth transition. Under the driving action of the first driving member 171, the cleaning brush roller 110 can slide from the second guide groove 137 to the first guide groove 135, thereby leaving the brush roller accommodating groove 139, and can also slide from the first guide groove 135 to the second guide groove 137, thereby entering the brush roller accommodating groove 139. The shape of the second guide groove 137 is consistent with the movement trajectory of the cleaning brush roller 110 leaving or entering the brush roller accommodating groove 139, and can play a certain limiting effect.

[0068] In this embodiment, the transmission box 175 is provided with an inclined guide hole 175e, and the extending direction of the inclined guide hole 175e is set at an angle with the moving direction of the transmission box 175. The cleaning brush roller 110 or the second driving member 173 is slidably penetrated in the inclined guide hole 175e, and is used to slide along the inclined guide hole 175e under the drive of the first driving member 171, so that the cleaning brush roller 110 moves along the second guide groove 137. Specifically, the output shaft of the second driving member 173 is slidably penetrated in the inclined guide hole 175e. By providing the inclined guide hole 175e, the cleaning brush roller 110 or the second driving member 173 can slide along the inclined guide hole 175e under the drive of the first driving member 171, so that the cleaning brush roller 110 moves along the second guide groove 137, and the function of entering or leaving the brush roller accommodating groove 139 is realized, which can be realized by the first driving member 171, and there is no need to set up an additional driving mechanism for driving the cleaning brush roller 110 to enter or leave the brush roller accommodating groove 139, thereby simplifying the structure.

[0069] In other preferred embodiments of the present invention, a bushing can be arranged around the output shaft of the second driving member 173, the bushing is slidably inserted into the inclined guide hole 175e, and the bushing is fixed to the motor housing of the second driving member 173, thereby preventing the output shaft of the second driving member 173 from directly inserting into the inclined guide hole 175e, thereby avoiding friction between the output shaft of the second driving member 173 and the inclined guide hole 175e when rotating.

[0070] It should be noted that the angled setting mentioned in this embodiment refers to an acute angle setting between the two, excluding the right angle setting, so that the inclined guide hole 175e is inclined relative to the movement direction, which is convenient for applying force.

[0071] It should also be noted that the inclination direction of the inclined guide hole 175e in this embodiment is opposite to the inclination direction of the second guide groove 137, and is opposite to the movement direction of the cleaning brush roller 110 when leaving the brush roller accommodating groove 139. Specifically, when the cleaning brush roller 110 leaves the brush roller accommodating groove 139, the cleaning brush roller 110 is subjected to a relatively upward resisting force under the resisting action of the lower side of the inclined guide hole 175e. At the same time, since the inclined guide hole 175e is arranged obliquely, the cleaning brush roller 110 can move upward along the inclined guide hole 175e under the action of the resisting force, so that the cleaning brush roller 110 moves along the second guide groove 137 and leaves the brush roller accommodating groove 139. When the cleaning brush roller 110 enters the brush roller accommodating groove 139, the cleaning brush roller 110 is subjected to a downward force due to the force of gravity or the resistance of the upper side of the inclined guide hole 175e. At the same time, due to the inclined setting of the inclined guide hole 175e, the cleaning brush roller 110 can move downward along the inclined guide hole 175e under the action of gravity or the resistance force, thereby enabling the cleaning brush roller 110 to move along the second guide groove 137 and enter the brush roller accommodating groove 139.

[0072] In this embodiment, the transmission box 175 is provided with an inclined limiting hole 175f, the extending direction of the inclined limiting hole 175f is set at an angle with the moving direction of the transmission box 175, and the second driving member 173 is provided with a positioning slider 173a, the positioning slider 173a is slidably accommodated in the inclined limiting hole 175f, and the long axis width of the positioning slider 173a is greater than the width of the inclined limiting hole 175f. By providing the positioning slider 173a accommodated in the inclined limiting hole 175f on the second driving member 173, and the long axis width of the positioning slider 173a is greater than the width of the inclined limiting hole 175f, the positioning slider 173a can be prevented from rotating in the inclined limiting hole 175f, thereby preventing the second driving member 173 from rotating relative to the transmission box 175, thereby ensuring that the second driving member 173 can stably drive the cleaning brush roller 110 to rotate.

[0073] In this embodiment, the positioning slider 173a is a waist-shaped slider, which is slidably accommodated in the inclined limiting hole 175f, and the extending direction of the inclined limiting hole 175f is parallel to the extending direction of the inclined guide hole 175e, so that the positioning slider 173a can move synchronously and parallelly with the cleaning brush roller 110, and the positioning slider 173a and the cleaning brush roller 110 are relatively fixed, thereby preventing the second driving member 173 from rotating. Of course, the positioning slider 173a here can also be a rectangular slider or an elliptical slider or other shapes, which are not specifically limited here.

[0074] It should be noted that the long axis width of the positioning slider 173a mentioned in this embodiment refers to the distance between the two farthest points on the cross section of the positioning slider 173a. For example, when the positioning slider 173a is a waist-shaped slider, the long axis width refers to the distance between the two ends of the waist-shaped slider in the long axis direction. When the positioning slider 173a is a rectangular slider, the long axis width refers to the distance between two points on the diagonal line.

[0075] To sum up, the air conditioner self-cleaning mechanism 100 provided in this embodiment has the following driving process. When cleaning is needed, the first driving member 171 and the second driving member 173 are started. The second driving member 173 drives the cleaning brush roller 110 to rotate. The first driving member 171 drives the driving gear 177 to rotate. Under the meshing action of the transmission rack 191, the first driving member 171 drives the transmission box 175 to move along the driving slide groove 151. The cleaning brush roller 110 first slides upward along the inclined guide hole 175e under the drive of the second driving member 173, and moves upward along the second guide groove 137 and enters the first guide groove 135, so that the cleaning brush roller 110 leaves the brush roller accommodating groove 139. Under the continued driving action of the first driving member 171, the cleaning brush roller 110 moves along the first guide groove 135 and moves along the width direction of the air duct 180 to achieve cleaning of the air duct 180. When the cleaning brush roller 110 moves to the upper limit position along the first guide groove 135, the air sweeping gap is narrowed, so that the wind wheel and the cleaning brush roller 110 can contact each other. At this time, the first driving member 171 and the second driving member 173 are stopped, and the wind wheel is started at a low speed to clean the wind wheel. After the cleaning is completed, the first driving member 171 is started in reverse, so as to drive the cleaning brush roller 110 to move downward along the first guide groove 135 and enter the second guide groove 137. After entering the second guide groove 137, the cleaning brush roller 110 is driven by the second driving member 173 to move downward along the inclined guide hole 175e, so as to bring the cleaning brush roller 110 into the brush roller accommodating groove 139, so as to store the cleaning brush roller 110 and complete the cleaning work. The air conditioner self-cleaning mechanism 100 provided in this embodiment has a stable drive, and can realize automatic cleaning of the air duct 180 and the wind wheel, and has a good cleaning effect.
