DETAILED DESCRIPTION

[0032] 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Combine the following Figure 1-Figure 12 The air duct dust removal device according to an embodiment of the present invention and the air conditioner indoor unit 100 having the same are described in detail.

[0034] Reference Figure 1-Figure 4 As shown, the air duct dust removal device according to the embodiment of the present invention may include: an air duct plate 1, a dust removal brush 2, a magnet 3 and a driving device, the air duct plate 1 has an air outlet surface 11, the dust removal brush 2 is arranged on the side of the air duct plate 1 where the air outlet surface 11 is located, and the dust removal brush 2 includes a brush head body 21 and a magnetic core 22, the brush head body 21 is suitable for fitting with the air outlet surface 11, so that when the dust removal brush 2 moves relative to the air duct plate 1, the surface of the air outlet surface 11 of the air duct plate 1 can be wiped to achieve the purpose of cleaning the air outlet surface 11 of the air duct plate 1. The magnetic core 22 is installed on the brush head body 21, and optionally, the magnetic core 22 and the brush head body 21 can be bonded and fixed, or the magnetic core 22 can be embedded inside the brush head body 21.

[0035] Optionally, the brush head body 21 can be sponge, silica gel, diatom mud, etc.

[0036] Optionally, the magnet 3 may be an electromagnet or a permanent magnet.

[0037] Reference Figure 1-Figure 4 As shown, the magnet 3 is arranged on the side of the air duct plate 1 away from the dust removal brush 2, and the driving device is used to drive the magnet 3 to move along the length direction of the air duct plate 1, so that the magnet 3 drives the dust removal brush 2 to move along the length direction of the air duct plate 1 through magnetic force. When the distance between the magnet 3 and the magnetic core 22 is less than the preset value, the magnetic force generated by the magnet 3 on the magnetic core 22 is sufficient to drive the dust removal brush 2 to move, or even move synchronously, so that the dust removal brush 2 wipes the air outlet surface 11 to clean the air duct plate 1. The length direction of the air duct plate 1 is the F1-F2 direction, and the magnet 3 drives the dust removal brush 2 to translate along the F1-F2 direction through magnetic force. Specifically, the magnet 3 can drive the dust removal brush 2 to move along the F1 direction, and can also drive the dust removal brush 2 to move along the F2 direction. In this reciprocating movement, the air outlet surface 11 can be wiped multiple times to keep the air outlet surface 11 of the air duct plate 1 clean.

[0038] Reference Figure 3 As shown, the dust brush 2 is arranged on the side where the air outlet surface 11 of the air duct plate 1 is located, and the magnet 3 is arranged on the side of the air duct plate 1 away from the dust brush 2. The dust brush 2 and the magnet 3 are separated on both sides of the air duct plate 1. The air outlet surface 11 can be cleaned in a large area by the dust brush 2. If the dust brush 2 is too dirty and needs to be cleaned, it is convenient to remove the dust brush 2. After the air duct dust removal device is applied to equipment, such as the air conditioner indoor unit 100, the air outlet surface 11 is arranged opposite to the air outlet 201 of the air conditioner indoor unit 100, and the leeward side 12 is away from the air outlet 201. In this way, when the air duct is discharging air, the magnet 3 has little effect on the air outlet process, so that the air outlet noise is small and the air outlet loss is small.

[0039] The air duct dust removal device may include a controller, and the driving device may be electrically connected to the controller. The controller is used to control the action of the driving device, so that the driving device drives the magnet 3 to move. The controller may also fix the magnet 3 at a specific position by controlling the driving device.

[0040] According to the air duct dust removal device of the embodiment of the present invention, by using the magnet 3 to drive the dust removal brush 2 to move, the magnet 3 and the driving device can be hidden on the leeward side 12 of the air duct plate 1, so that the air outlet surface 11 of the air duct plate 1 is relatively neat and has a better appearance, and the dust coming from the air outlet 201 is not easy to fall on the magnet 3 and the driving device, which reduces the cleaning difficulty of the air duct dust removal device. At the same time, the magnet 3 and the driving device are hidden on the leeward side 12 of the air duct plate 1, so that there are fewer parts on the side where the air outlet surface 11 is located. When the air duct is discharging air, the magnet 3 and the driving device have less influence on the air outlet process, so that the air outlet noise is small and the air outlet loss is small. In addition, the dust removal brush 2 moves along the air duct plate 1, which can solve the problem of troublesome air duct cleaning without manual intervention.

[0041] In some embodiments of the present invention, reference Figure 6 As shown, the driving device may include a magnetic track 41 and a wire 42, the magnetic track 41 extends along the length direction of the air duct plate 1 (i.e., the F1-F2 direction), the wire 42 is wound on the magnetic track 41 along the length direction of the magnetic track 41, the magnet 3 is sleeved outside the magnetic track 41, and when the wire 42 is a positive current, the magnetic track 41 generates a first driving force for the magnet 3 to move in a first direction; when the wire 42 is a reverse current, the magnetic track 41 generates a second driving force for the magnet 3 to move in a second direction, and the first direction is opposite to the second direction. Specifically, when the wire 42 is a positive current, the current and the magnetic track 41 generate electromagnetic induction, and the generated electromagnetic force is the first driving force, and the first driving force can move the magnet 3 in the first direction; when the wire 42 is a reverse current, the current and the magnetic track 41 generate electromagnetic induction, and the generated electromagnetic force is the second driving force, and the second driving force can move the magnet 3 in the second direction.

[0042] Optionally, the first direction may be the F1 direction, and the second direction may be the F2 direction. Figure 6 As shown, the magnetic track 41 extends along the F1-F2 direction. When the conductor 42 has a forward current, the magnetic track 41 drives the magnet 3 to move along the F1 direction, and the magnet 3 then drives the dust removal brush 2 to move along the F1 direction; when the conductor 42 has a reverse current, the magnetic track 41 drives the magnet 3 to move along the F2 direction, and the magnet 3 then drives the dust removal brush 2 to move along the F2 direction.

[0043] In some embodiments of the present invention, reference Figure 7-Figure 8As shown, the driving device may include a driving motor and a screw 43, the driving motor is in transmission connection with the screw 43, the screw 43 can rotate relative to the air duct plate 1, the screw 43 extends along the length direction of the air duct plate 1, and the magnet 3 is sleeved outside the screw 43 and threadedly engaged with the screw 43. Specifically, when the screw 43 rotates forward, the magnetic track 41 drives the magnet 3 to move in the F1 direction, and the magnet 3 then drives the dust removal brush 2 to move in the F1 direction; when the screw 43 rotates reversely, the magnetic track 41 drives the magnet 3 to move in the F2 direction, and the magnet 3 then drives the dust removal brush 2 to move in the F2 direction. Refer to Figure 7-Figure 8 As shown, the magnet 3 has a nut portion 44 , and the magnet 3 is fixed to the nut portion 44 . When the screw rod 43 rotates, the nut portion 44 moves along the axis of the screw rod 43 , thereby driving the magnet 3 to move along the axis of the screw rod 43 .

[0044] In some embodiments of the present invention, reference Figure 9-10 As shown, the driving device may include a driving motor, a driving wheel 46, a driven wheel 47 and a belt 45, the driving wheel 46 and the driven wheel 47 are separated, the belt 45 is driven and supported by the driving wheel 46 and the driven wheel 47, the driving motor is used to drive the driving wheel 46 to rotate so as to move the belt 45, and the magnet 3 is installed on the belt 45. Specifically, when the belt 45 moves forward, the magnetic track 41 drives the magnet 3 to move in the F1 direction, and the magnet 3 further drives the dust removal brush 2 to move in the F1 direction; when the belt 45 moves reversely, the magnetic track 41 drives the magnet 3 to move in the F2 direction, and the magnet 3 further drives the dust removal brush 2 to move in the F2 direction.

[0045] In some embodiments of the present invention, reference Figure 11-Figure 12 As shown, a guide structure is provided on the side where the air outlet surface 11 is located, and the guide structure is arranged along the length direction of the air duct plate 1. The dust removal brush 2 is suitable for being guided by the guide structure when moving. In this way, when the dust removal brush 2 moves along the length direction of the air duct plate 1, the guide structure can guide the dust removal brush 2 to prevent the dust removal brush 2 from shaking randomly and affecting the wiping effect.

[0046] In some optional embodiments, referring to Figure 11-Figure 12 As shown, the guide structure includes a first guide bar 51 and a second guide bar 52, both of which are located on the air outlet surface 11 and separated, and are parallel to each other. Both of the first guide bar 51 and the second guide bar 52 extend along the length direction of the air duct plate 1, and the dust removal brush 2 is located between the first guide bar 51 and the second guide bar 52, and is suitable for stopping against the first guide bar 51 and the second guide bar 52 when the dust removal brush 2 moves. In this way, when the dust removal brush 2 moves along the length direction of the air duct plate 1, the first guide bar 51 and the second guide bar 52 can guide the dust removal brush 2 to prevent the dust removal brush 2 from shaking randomly and affecting the wiping effect.

[0047] Reference Fig.12As shown, the first guide strip 51 and the second guide strip 52 both extend along the F1 - F2 direction. When the dust removal brush 2 moves, the F1 end of the dust removal brush 2 stops against the first guide strip 51 , and the F2 end of the dust removal brush 2 stops against the second guide strip 52 .

[0048] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0049] In other optional embodiments, the guide structure can be a guide rod, which extends along the length direction of the air duct plate 1, and the dust removal brush 2 is inserted into the guide rod. In this way, when the dust removal brush 2 moves along the length direction of the air duct plate 1, the guide rod can guide the dust removal brush 2 to prevent the dust removal brush 2 from shaking randomly and affecting the wiping effect.

[0050] In some embodiments of the present invention, reference Figure 2 , Figure 4 As shown, the air duct dust removal device may further include a back plate 6, which is arranged on the side of the air duct plate 1 away from the dust removal brush 2, and the magnet 3 is arranged on the side of the back plate 6 away from the air duct plate 1, and a heat preservation layer 7 is arranged between the back plate 6 and the air duct plate 1, and the heat preservation layer 7 can reduce condensation on the air outlet surface 11 of the air duct plate 1, thereby preventing water from dripping from the air outlet 201 when there is too much condensation on the air duct plate 1 and affecting the user experience. Optionally, the heat preservation layer 7 may be sponge, silica gel, etc.

[0051] In some embodiments of the present invention, reference Figure 2-Figure 3 As shown, the air duct plate 1 has a leeward surface 12, the leeward surface 12 is opposite to the outlet surface 11, the magnet 3 is in contact with the leeward surface 12, and the roughness of the outlet surface 11 is smaller than that of the leeward surface 12. When the magnet 3 drives the dust removal brush 2 to move along the length direction of the air duct plate 1, the magnet 3 and the dust removal brush 2 are subjected to the same magnetic force. When the roughness of the outlet surface 11 is smaller than that of the leeward surface 12, the friction force on the magnet 3 is large, and the friction force on the dust removal brush 2 is small. The moving speed of the magnet 3 is not easy to exceed the moving speed of the dust removal brush 2, thereby ensuring the reliability of the magnetic drive.

[0052] In some embodiments of the present invention, the projection size of the magnet 3 on the air duct plate 1 is larger than the projection size of the dust removal brush 2 on the air duct plate 1. In this way, it can be ensured that the magnet 3 is larger than the dust removal brush 2, reducing the probability of the magnet 3 and the dust removal brush 2 being completely misaligned, thereby improving the reliability of the magnetic drive.

[0053] In some embodiments of the present invention, the air duct dust removal device may further include a first speed sensor and a second speed sensor, the first speed sensor is used to detect the moving speed of the dust removal brush 2, and the second speed sensor is used to detect the moving speed of the magnet 3. When the speed difference between the dust removal brush 2 and the magnet 3 exceeds a preset value, the driving device adjusts the position of the magnet 3. Specifically, when the speed difference between the dust removal brush 2 and the magnet 3 exceeds a preset value, there will also be a difference in the position between the dust removal brush 2 and the magnet 3, causing the dust removal brush 2 and the magnet 3 to be staggered. At this time, the driving device adjusts the position of the magnet 3 so that the magnet 3 is again arranged relative to the dust removal brush 2, so as to drive the dust removal brush 2 to move by magnetic force.

[0054] Specifically, the first speed sensor and the second speed sensor are also electrically connected to the controller. The controller receives the speed signals collected by the first speed sensor and the second speed sensor. When the difference between the speed signals collected by the first speed sensor and the second speed sensor exceeds a preset value, the controller controls the drive device to operate, and the drive device adjusts the position of the magnet 3.

[0055] In some embodiments of the present invention, reference Figure 1 , Figure 3-Figure 5 As shown, the dust removal brush 2 is an arc-shaped structure, and the air outlet surface 11 of the air duct plate 1 is also an arc-shaped surface. The dust removal brush 2 and the air outlet surface 11 have the same degree of curvature, so that the dust removal brush 2 and the air outlet surface 11 can be well fitted, which is conducive to improving the wiping effect of the dust removal brush 2 on the air outlet surface 11. The length direction of the dust removal brush 2 is arranged to intersect with the length direction of the air duct plate 1. Optionally, the angle formed by the length direction of the dust removal brush 2 and the length direction of the air duct plate 1 can be 30° to 90°. For example, the length direction of the dust removal brush 2 is perpendicular to the length direction of the air duct plate 1, that is, the angle formed by the length direction of the dust removal brush 2 and the length direction of the air duct plate 1 is 90°. Specifically, the length direction of the air duct plate 1 is the F1-F2 direction, and the length direction of the dust removal brush 2 is the F3-F4 direction. The F3-F4 direction is perpendicular to the F1-F2 direction. In this way, even if the length of the dust removal brush 2 is set shorter, the air duct plate 1 can be completely covered in the F3-F4 direction.

[0056] In other embodiments, the length of the dust removal brush 2 may also be extended to the leeward surface 12, so that when the dust removal brush 2 moves along the length direction of the air duct plate 1, both the air outlet surface 11 and the leeward surface 12 can be wiped, and the dust removal effect is good.

[0057] Combine the following Figure 1-Figure 3 , Figure 5-Figure 6 , Fig.11 A dust removal device for an air duct according to a specific example of the present invention is described in detail.

When the dust removal brush 2 moves, the F1 end of the dust removal brush 2 stops at the first guide bar 51, and the F2 end of the dust removal brush 2 stops at the second guide bar 52. The dust removal brush 2 is an arc-shaped structure. The structure is as follows: the length direction of the dust removal brush 2 is F3-F4 direction, the F3-F4 direction is perpendicular to the F1-F2 direction, the dust removal brush 2 includes a brush head body 21 and a magnetic core 22, the brush head body 21 is fitted with the wind outlet surface 11, the magnetic core 22 is installed on the brush head body 21, the magnet 3 is fitted with the leeward surface 12, the magnetic track 41 extends along the F1-F2 direction, the wire 42 is wound on the magnetic track 41, the magnet 3 is sleeved outside the magnetic track 41, when the wire 42 has a forward current, the magnetic track 41 drives the magnet 3 to move along the F1 direction, and the magnet 3 further drives the dust removal brush 2 to move along the F1 direction; when the wire 42 has a reverse current, the magnetic track 41 drives the magnet 3 to move along the F2 direction, and the magnet 3 further drives the dust removal brush 2 to move along the F2 direction.

[0063] An air conditioner indoor unit 100 according to another embodiment of the present invention includes the air duct dust removal device of the above embodiment.

[0064] Reference Fig.12 As shown, the air-conditioning indoor unit 100 also includes a shell 20, which has a containing cavity. The shell 20 is provided with an air outlet 201. The air duct dust removal device is installed in the containing cavity. The air duct plate 1 is arranged opposite to the air outlet 201. Specifically, the air outlet surface 11 is arranged opposite to the air outlet 201, and the leeward surface 12 is away from the air outlet 201. The air duct plate 1 includes an air duct plate body 13 and an air duct plate extension section 14. The air duct plate extension section 14 is connected to the air duct plate body 13. The orthographic projection of the air outlet 201 on the air duct plate 1 is located on the air duct plate body 13. The dust removal brush 2 can move on the air duct plate body 13 and the air duct plate extension section 14. When the dust removal brush 2 moves to the air duct plate extension section 14, the dust removal brush 2 can be blocked by the shell 20 to be hidden. The position of the dust removal brush 2 has little effect on the air outlet volume. The dust removal brush 2 is not easily exposed from the air outlet 201. The appearance of the air-conditioning indoor unit 100 is relatively neat. Fig.12 The position shown is the position where the dust removal brush 2 is located on the air duct plate extension section 14 and the dust removal brush 2 is blocked by the housing 20 .

[0065] Reference Fig.12 As shown, the air conditioner indoor unit 100 further includes a frame 30 , which is installed in the accommodating cavity, and the air duct plate 1 is installed on the frame 30 , and the frame 30 can provide support for the air duct plate 1 .

[0066] According to the air conditioner indoor unit 100 of the embodiment of the present invention, the air duct dust removal device thereof uses the magnet 3 to drive the dust removal brush 2 to move, and can hide the magnet 3 and the driving device on the leeward side 12 of the air duct plate 1, so that the air outlet surface 11 of the air duct plate 1 is relatively tidy and has a better appearance, and the dust coming from the air outlet 201 is not easy to fall on the magnet 3 and the driving device, which reduces the cleaning difficulty of the air duct dust removal device. At the same time, the magnet 3 and the driving device are hidden on the leeward side 12 of the air duct plate 1, so that there are fewer parts on the side where the air outlet surface 11 is located. When the air duct is discharging air, the magnet 3 and the driving device have less influence on the air outlet process, so that the air outlet noise is small and the air outlet loss is small. In addition, the dust removal brush 2 moves along the air duct plate 1, which can solve the problem of troublesome air duct cleaning without manual intervention.
