DETAILED DESCRIPTION

[0028] 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.

[0029] First embodiment

[0030] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a dust removal device 100 for removing dust from an air duct 110 in an air conditioner. The dust removal device 100 can remove dust from the air duct 110 without disassembling the air conditioner, has high dust removal efficiency and good dust removal effect, and improves the cleanliness of the air discharged from the air conditioner.

[0031] It should be noted that the dust removal device 100 is applied to a wall-mounted air conditioner, which is mounted on a wall indoors and can blow hot or cold air indoors to adjust the indoor temperature. The dust removal device 100 can remove dust from the air duct 110 in the wall-mounted air conditioner to remove dust and other dirt in the air duct 110 and improve the cleanliness of the air outlet. However, this is not limited to this. In other embodiments, the dust removal device 100 can also be applied to a vertical air conditioner or a central air conditioner, and the application scenario of the dust removal device 100 is not specifically limited.

[0032] The dust removal device 100 includes an air duct 110, a driving mechanism 120, a dust collecting plate 130 and a negative pressure mechanism 140. The dust collecting plate 130 is arranged in the air duct 110 and extends along the length direction of the air duct 110, that is, the length direction of the dust collecting plate 130 is the same as the length direction of the air duct 110, so as to increase the area range where the dust collecting plate 130 can collect dust, improve the dust removal efficiency, and enhance the dust removal effect. The dust collecting plate 130 is connected to the negative pressure mechanism 140, and the negative pressure mechanism 140 is used to generate negative pressure to realize the dust collection function of the dust collecting plate 130. The driving mechanism 120 is transmission-connected to the dust collecting plate 130. The driving mechanism 120 can drive the dust collecting plate 130 to move. The dust collecting plate 130 can move along the inner circumference of the air duct 110 driven by the driving mechanism 120, and dust the air duct 110 under the action of the negative pressure mechanism 140, that is, the dust collecting plate 130 can perform dust collection while moving along the inner circumference of the air duct 110, so as to remove dust and other dirt in the air duct 110, and the dust removal effect is good.

[0033] It should be noted that the air duct 110 is in a volute shape, the cross section of the inner wall of the air duct 110 is arc-shaped, the inner circumferential direction of the air duct 110 is the extension direction of the inner wall of the air duct 110, and the inner circumferential direction of the air duct 110 is perpendicular to the length direction of the air duct 110. The dust collecting plate 130 moves along the inner circumferential direction of the air duct 110, that is, the dust collecting plate 130 moves along the inner wall of the air duct 110 to remove dust and other dirt on the inner wall of the air duct 110.

[0034] Please refer to Figure 3It is worth noting that a dust collection surface 131 is provided on one side of the dust collection plate 130 close to the inner wall of the air duct 110. The dust collection surface 131 is spaced apart from the inner wall of the air duct 110 to avoid interference between the dust collection plate 130 and the inner wall of the air duct 110 during movement. The dust collection plate 130 can remove dirt on the inner wall of the air duct 110 through the dust collection surface 131 to achieve the dust removal function on the inner wall of the air duct 110.

[0035] In this embodiment, the dust suction plate 130 is provided with a dust suction cavity 132, and a dust suction port 133 is provided on the dust suction surface 131. The dust suction port 133 is connected to the negative pressure mechanism 140 through the dust suction cavity 132. When the negative pressure mechanism 140 is activated, the air pressure at the position corresponding to the dust suction port 133 is greater than the air pressure in the negative pressure mechanism 140, so that the dirt at the position corresponding to the dust suction port 133 is sucked into the negative pressure mechanism 140, thereby realizing the dust suction function. Specifically, the dust suction port 133 is used for dirt to pass through, and the dirt on the inner wall of the air duct 110 can enter the dust suction cavity 132 through the dust suction port 133, and then enter the negative pressure mechanism 140.

[0036] In this embodiment, the dust collecting surface 131 is covered with a brush portion 134, which is used to clean the inner wall of the air duct 110, so as to realize the cleaning function of the inner wall of the air duct 110 and improve the dust removal effect. Specifically, when the dust collecting plate 130 moves along the inner circumference of the air duct 110, the brush portion 134 can move along the inner wall of the air duct 110 synchronously driven by the dust collecting plate 130 to clean the inner wall of the air duct 110, and the swept dirt is quickly sucked away by the dust collecting plate 130, so as to improve the dust removal effect on the inner wall of the air duct 110.

[0037] Please refer to Figure 4 and Figure 5 The driving mechanism 120 includes a driving motor 121 and a transmission assembly 122. The driving motor 121 is connected to the dust collecting plate 130 through the transmission assembly 122. The driving motor 121 can output power to the transmission assembly 122, and the dust collecting plate 130 can move under the drive of the transmission assembly 122 to remove dust from the inner wall of the air duct 110.

[0038] The transmission assembly 122 includes a first pulley 123, a second pulley 124, a transmission belt 125 and a mounting plate 126, wherein the first pulley 123 and the second pulley 124 are both mounted on the mounting plate 126 and can rotate relative to the mounting plate 126, and the mounting plate 126 can limit the first pulley 123 and the second pulley 124. The driving motor 121 passes through the mounting plate 126 and is in transmission connection with the first pulley 123, and the driving motor 121 can drive the first pulley 123 to rotate. The first pulley 123 is connected to the second pulley 124 through the transmission belt 125, and the first pulley 123 can drive the second pulley 124 to rotate through the transmission belt 125, that is, the first pulley 123 is a driving wheel, and the second pulley 124 is a driven wheel, and the driving motor 121 can synchronously drive the first pulley 123, the transmission belt 125 and the second pulley 124 to rotate. The dust collecting plate 130 is fixedly connected to the transmission belt 125 , and the rotation of the transmission belt 125 can synchronously drive the dust collecting plate 130 to move, so as to remove dust and clean the inner wall of the air duct 110 .

[0039] It should be noted that, since the inner side wall of the air duct 110 is arranged in an arc shape, that is, the inner circumference of the air duct 110 is an arc direction, it is necessary to limit the transmission belt 125 so that the transmission belt 125 extends along the inner circumference of the air duct 110. In this embodiment, the air duct 110 is provided with an end wall 111, and the end wall 111 is provided with a limiting groove 112. The transmission belt 125 is arranged in the limiting groove 112 and can rotate relative to the limiting groove 112. The limiting groove 112 is used to limit the transmission belt 125 so that the transmission belt 125 rotates along the inner circumference of the limiting groove 112. Specifically, the limiting groove 112 is arranged in an arc shape and extends along the inner circumference of the air duct 110. The curvature of the limiting groove 112 is the same as the curvature of the inner side wall of the air duct 110, so that the transmission belt 125 can rotate along the inner circumference of the air duct 110, thereby driving the dust collecting plate 130 to move along the inner circumference of the air duct 110. The first pulley 123 and the second pulley 124 are both disposed in the limiting groove 112 , wherein the first pulley 123 is located at one end of the limiting groove 112 , and the second pulley 124 is located at the other end of the limiting groove 112 , so as to tighten the transmission belt 125 , thereby realizing the function of driving the transmission belt 125 to rotate.

[0040] In this embodiment, the dust collecting plate 130 includes a plate body 135 and an extension portion 136. The extension portion 136 is fixedly connected to the end of the plate body 135 and is fixedly connected to the transmission belt 125. The dust collecting port 133 and the brush portion 134 are both arranged on the plate body 135. The plate body 135 is connected to the negative pressure mechanism 140. The plate body 135 is used to clean and vacuum the inner wall of the air duct 110. The rotation of the transmission belt 125 can drive the extension portion 136 to move, thereby driving the plate body 135 to move along the inner circumference of the air duct 110. The plate body 135 can clean and vacuum the inner wall of the air duct 110 during the movement. Specifically, the extension portion 136 is fixedly connected to the inner side of the transmission belt 125, and the outer side of the transmission belt 125 is arranged to fit the inner circumferential wall of the limiting groove 112 to prevent the movement of the extension portion 136 from interfering with the limiting groove 112. The extension portion 136 extends from one side of the transmission belt 125, and the first pulley 123 and the second pulley 124 extend from the other side of the transmission belt 125. The widths of the first pulley 123 and the second pulley 124 are the same, and the width of the transmission belt 125 is greater than the sum of the width of the extension portion 136 and the width of the first pulley 123, so as to prevent the extension portion 136 from interfering with the first pulley 123 or the second pulley 124 during the movement of the transmission belt 125.

[0041] In this embodiment, the number of the driving mechanism 120 and the extension part 136 are both two, and the two extension parts 136 are arranged at the two ends of the plate body 135. Each driving motor 121 is connected to an extension part 136 through a transmission assembly 122, that is, one extension part 136 is fixedly connected to the inner side of one transmission belt 125, and the other extension part 136 is fixedly connected to the inner side of another transmission belt 125. The two driving motors 121 rotate synchronously to improve the stability of the movement of the dust collecting plate 130 and ensure that the dust collecting plate 130 can move smoothly along the inner circumference of the air duct 110. Further, the air duct 110 has two end walls 111, and the two end walls 111 are arranged parallel and spaced along the length direction of the air duct 110. A limiting groove 112 is opened on each end wall 111, and each transmission belt 125 is arranged in a limiting groove 112 to rotate along the inner circumference of the air duct 110 under the limiting action of the limiting groove 112.

[0042] In this embodiment, the transmission belt 125 is made of rubber material, and the transmission belt 125 is flexible and can be deformed under the limiting action of the limiting groove 112. The inner peripheral wall of the limiting groove 112 is provided with a lubricating coating to reduce the friction between the inner peripheral wall and the transmission belt 125, so as to ensure that the transmission belt 125 can rotate stably, thereby driving the dust collecting plate 130 to move along the inner circumference of the air duct 110. However, it is not limited to this. In other embodiments, the transmission belt 125 can also be made of silicone material, and the material of the transmission belt 125 is not specifically limited.

[0043] In the dust removal device 100 described in the embodiment of the present invention, the dust collecting plate 130 is arranged in the air duct 110 and extends along the length direction of the air duct 110. The dust collecting plate 130 is connected to the negative pressure mechanism 140, and the negative pressure mechanism 140 is used to generate negative pressure. The driving mechanism 120 is in transmission connection with the dust collecting plate 130. The dust collecting plate 130 can move along the inner circumference of the air duct 110 under the drive of the driving mechanism 120, and dust the air duct 110 under the action of the negative pressure mechanism 140. Compared with the prior art, the dust removal device 100 provided by the present invention adopts the dust collecting plate 130 connected to the driving mechanism 120 and the negative pressure mechanism 140 respectively, so that the air duct 110 can be dusted and cleaned without disassembling the air conditioner, and the dust removal efficiency is high, the dust removal effect is good, and the cleanliness of the air discharged by the air conditioner is improved.

[0044] Second embodiment

[0045] Please refer to Figure 6 , Figure 7 , Figure 8 and Fig. 9 The present invention provides a dust removal device 100. Compared with the first embodiment, the difference of this embodiment is that the air duct 110 is provided with a receiving groove 113 for receiving the dust collecting plate 130, and the transmission structure is different.

[0046] It is worth noting that the receiving groove 113 extends along the length direction of the air duct 110, that is, the extending direction of the receiving groove 113 is the same as the length direction of the air duct 110 and the length direction of the dust collecting plate 130. The dust collecting plate 130 is received in the receiving groove 113, and the dust collecting plate 130 can be moved out of or returned to the receiving groove 113 under the action of the driving mechanism 120. The receiving groove 113 can shield the dust collecting plate 130 to prevent the dust collecting plate 130 from blocking and affecting the air outlet of the air duct 110.

[0047] In this embodiment, the receiving groove 113 is arranged at the bottom of the air duct 110, and the dust collecting plate 130 can be moved out of the receiving groove 113 under the action of the driving mechanism 120, and move upward along the inner circumference of the air duct 110 to remove dust and clean the inner wall of the air duct 110; when the dust collecting plate 130 moves to the extreme position, the dust collecting plate 130 can move back under the action of the driving mechanism 120, that is, move downward along the inner circumference of the air duct 110 until it returns to the receiving groove 113.

[0048] In this embodiment, the receiving groove 113 includes a first side wall 114, a bottom wall 115 and a second side wall 116. The first side wall 114 and the second side wall 116 are arranged opposite to each other, and the first side wall 114 is fixedly connected to the second side wall 116 through the bottom wall 115.

[0049] It should be noted that the transmission assembly 122 also includes a third pulley 127, which is mounted on the mounting plate 126 and can rotate relative to the mounting plate 126. The transmission belt 125 is sleeved outside the first pulley 123, the second pulley 124 and the third pulley 127. The first pulley 123 is connected to the second pulley 124 and the third pulley 127 through the transmission belt 125, that is, the first pulley 123 is a driving wheel, and the second pulley 124 and the third pulley 127 are both driven wheels. The driving motor 121 can synchronously drive the first pulley 123, the second pulley 124, the third pulley 127 and the transmission belt 125 to rotate, thereby driving the dust collecting plate 130 to move, so as to remove dust from the inner wall of the air duct 110.

[0050] In this embodiment, the limiting groove 112 is bent, and includes a first slot 117 and a second slot 118 arranged at an angle, and the first slot 117 is connected to the second slot 118. The position of the first slot 117 corresponds to the position of the accommodating groove 113, and the first slot 117 extends from the inside of the accommodating groove 113 to the outside of the accommodating groove 113; the second slot 118 is arranged in an arc shape and extends along the inner circumference of the air duct 110, and the curvature of the second slot 118 is the same as the curvature of the inner wall of the air duct 110. When the transmission belt 125 drives the extension part 136 to move from the first slot hole 117 to the second slot hole 118, the dust collecting plate 130 moves out from the accommodating groove 113; when the transmission belt 125 drives the extension part 136 to move in the second slot hole 118 and gradually moves away from the first slot hole 117, the dust collecting plate 130 moves upward along the inner circumference of the air duct 110 to remove dust and clean the inner side wall of the air duct 110; when the transmission belt 125 drives the extension part 136 to move in the second slot hole 118 and gradually approaches the first slot hole 117, the dust collecting plate 130 moves downward along the inner circumference of the air duct 110 to remove dust and clean the inner side wall of the air duct 110 again; when the transmission belt 125 drives the extension part 136 to move from the second slot hole 118 to the first slot hole 117, the dust collecting plate 130 returns to the accommodating groove 113.

[0051] Specifically, the first pulley 123, the second pulley 124 and the third pulley 127 are all arranged in the limiting groove 112, wherein the first pulley 123 is located at the junction of the first slot hole 117 and the second slot hole 118, the second pulley 124 is located at the end of the second slot hole 118 away from the first pulley 123, and the third pulley 127 is located at the end of the first slot hole 117 away from the first pulley 123, and the first pulley 123, the second pulley 124 and the third pulley 127 work together to tighten the transmission belt 125, thereby realizing the function of driving the transmission belt 125 to rotate.
