Fig. 2 is a schematic exploded view of a cleaning device 1 according to one embodiment of the invention. Fig. 3 is a schematic configuration diagram of cleaning device 1 according to an embodiment of the present invention, as viewed from another angle. Fig. 4 is a schematic exploded view of sweeping device 1 according to one embodiment of the present invention, viewed from another angle.
Referring to fig. 1 to 4, the sweeping device 1 may include at least one dust removing drum brush 100, an adsorption drum brush 200, and a dust box 900. The dust removing roller brush 100 is formed with a plurality of protrusions configured to contact the filter screen 600 of the indoor unit of the wall-mounted air conditioner and push the dust attached to the filter screen 600 to the outside of the filter screen 600 through the plurality of protrusions, so that the dust is separated from the filter screen 600. The adsorption drum brush 200 is configured to contact at least a portion of an outer side surface of the screen 600 to adsorb dust detached from the screen 600. The dust box 900 has an upward opening and is disposed inside the indoor unit so as to be laterally drawn out therefrom. Further, the adsorption rolling brush 200 is rotatably installed on the dust collection box 900 above the opening, so that the dust collection box 900 collects dust falling from above the opening.
Specifically, the dust-removing roller brush 100 and the adsorption roller brush 200 may be each configured to be rotatably disposed in a lateral direction inside an indoor unit of a wall-mounted type air conditioner. The cleaning device 1 pushes the dust attached to the inside of the mesh of the filter screen 600 to the outside of the filter screen 600 by means of the protrusion of the dust removing rolling brush 100 in a "push-out" manner. Further, the sweeping device 1 adsorbs and collects the dust pushed up to have substantially escaped from the mesh by the adsorption roller brush 200.
The cleaning apparatus 1 of the present invention loosens the dust adsorbed to the filter 600 by the dust removing brush roll 100 and at least partially separates from the mesh of the filter 600. Therefore, the problem that part of dust cannot be completely removed due to the fact that the filter screen 600 is cleaned by a direct sweeping manner and the like which are commonly used in the prior art can be avoided.
Furthermore, the cleaning device 1 of the present invention absorbs and collects the dust pushed out of the mesh of the filter screen 600 in time through the special absorbing rolling brush 200, so as to prevent the dust from falling to other positions inside the indoor unit, and the absorbing rolling brush 200 can stick and collect the dust only by contacting with the outer surface of the filter screen 600, so that the brushing force applied to the filter screen 600 is greatly reduced, the possibility of possible damage is reduced, and the filter screen 600 has a longer service life.
Furthermore, the cleaning device 1 of the present invention can directly extract the dust collecting box 900 through the dust collecting box 900 which can be directly extracted when the dust collecting box 900 collects dust for a certain time and needs to be dumped, and does not need to open the panel of the indoor unit, thereby simplifying the cleaning operation procedure and making the cleaning of the indoor unit simpler and more convenient.
In some embodiments of the present invention, the dust-removing brush and the adsorption drum brush 200 are closely disposed at both sides of the filter screen 600 and are configured to be controllably rotated. Therefore, after the dust removing brush drives the dust removing brush to roll on the inner side of the filter screen 600 and push out dust on the dust removing brush, the part of the filter screen 600 which is subjected to preliminary dust removal is contacted with the adsorption rolling brush 200 arranged on the outer side of the filter screen 600 so as to completely separate the dust from the filter screen 600, so that the dust removing brush and the adsorption rolling brush 200 are contacted with the filter screen 600 to preliminarily loosen the dust and completely strip the dust, and the cleaning effect of the cleaning device 1 on the filter screen 600 is greatly improved. Furthermore, the indoor unit provided with the cleaning device 1 of the present invention can avoid dust raising inside the indoor unit by the adsorption rolling brush 200, so that the frequency of cleaning the fan and the heat exchanger of the indoor unit can be greatly reduced, and the indoor unit can be kept clean conveniently.
Fig. 5a is a schematic structural view of a holder 500 of the cleaning apparatus 1 and a filter screen 600 mounted thereon according to an embodiment of the present invention. Fig. 5b is a schematic exploded view of a holder 500 and a filter screen 600 of a cleaning device 1 according to an embodiment of the invention. To more clearly illustrate the structure of the bracket 500, some of the protrusions are omitted in fig. 5a and 5 b.
Referring to fig. 1-5, in some embodiments of the present invention, sweeping device 1 further comprises at least one stand 500. The carrier 500 is configured such that the screen 600 surrounds both sides of the carrier 500 in a closed loop and supports the screen 600 at least from the inside. Further, the dust-removing roll brush 100 is rotatably provided at one end of the bracket 500, and the other end of the bracket 500 is provided with a support roller 510. Specifically, a portion of the mesh cloth of the filter screen 600 is respectively folded around the outside of the dust-removing roller brush 100 and the support roller 510 such that the filter screen 600 is wound around both sides of the bracket 500, whereby the ring-shaped filter screen 600 can be circularly moved along the basic shape of the surface of the bracket 500. That is, the bracket 500 may be configured to at least partially cover the upper sides of the heat exchanger and the fan of the indoor unit, so that air entering the indoor unit flows through the fan and the heat exchanger after being filtered by the filter screen 600 installed thereon.
Specifically, the upper and lower ends of the bracket 500 may be respectively provided with the dust-removing roll brush 100 and the support roller 510 for supporting the filter screen 600 arranged in a ring shape. Preferably, the dust-removing roll brush 100 may be provided at one end of the bracket 500 near the lower portion of the indoor unit. Thereby, it is convenient to mount other components or structures of the cleaning device 1 near the dust-removing roll brush 100. Further, the dust removing roller brush 100 may be connected to a driving device such as a motor to form a driving wheel and drive the filter screen 600 to roll through the protrusions while rotating. The supporting roller 510 may rotate together with the dust-removing drum brush 100 to constitute a driven wheel and assist the dust-removing drum brush 100 in driving the filter screen 600 to roll. The support roller 510 may be fixed or driven to rotate by the filter screen 600 to adapt to different internal structures of the indoor unit.
Further, the support 500 may be configured to be irregular according to the internal structure of the indoor unit, and a plurality of net pressing structures 501 may be disposed thereon. The screen pressing structure 501 may be preferably provided at a portion of the bracket 500 where the bending angle is large, thereby preventing the ring screen 600 from running out of the basic locus defined by the surface of the bracket 500 at the turn of the bracket 500 and ensuring stable circulation of the ring screen 600. The net pressing structure 501 may be configured as a horizontal rod, the horizontal rod-shaped net pressing structure 501 extends along the horizontal direction and presses the outside of the filter screen 600 from the bending concave side of the bracket 500, and the left and right ends of the horizontal rod-shaped net pressing structure 501 may be respectively formed with hooks extending towards the bracket 500 to be clamped at the left and right frames of the bracket 500. In other embodiments of the present invention, the net pressing structure 501 may also be configured with blocking latches respectively disposed at the left and right frames of the bracket 500, and the blocking latches respectively press against the edge of the filter screen 600 to prevent the filter screen 600 from separating from the bracket 500 and prevent the filter screen 600 from moving laterally.
In some embodiments of the present invention, the bracket 500 may further include a plurality of limiting protrusions 502 configured to be spaced apart from the bent convex side of the bracket 500 along the left and right rims of the bracket 500, and the plurality of limiting protrusions 502 may define a rolling track of the filter screen 600 to prevent the filter screen 600 from moving laterally.
Fig. 6 is a schematic structural view of a cleaning part of the cleaning apparatus 1 according to one embodiment of the present invention, in which a dust removing roller brush 100, an adsorption roller brush 200, a dust removing shaft 400, and a dust collecting comb 300 are shown. In order to more clearly show the structure of the bracket 500, fig. 6 omits a part of the protrusion. Fig. 7a is a schematic partially enlarged view of the dust-removing drum brush 100 shown in fig. 6, in which the protrusions are shown.
Referring to fig. 7a, in some embodiments of the present invention, the plurality of protrusions of the dust-removing roller 100 may include a plurality of rows of pin groups 110 spaced apart along an axial direction of the dust-removing roller 100, each of the pin groups 110 includes a plurality of pins 111 annularly disposed on an outer circumferential side of the dust-removing roller 100, and the dust-removing roller 100 is configured to be rotated under control to drive the filter screen 600 to circularly roll, such that the mesh cloth continuously rolls and contacts the plurality of pins 111. Further, the plurality of pins 111 in each group of pin groups 110 extend radially and obliquely outward from the outer peripheral side of the rolling dust removing brush 100, and the inclination directions of the pins 111 in two adjacent groups of pin groups 110 in the axial direction of the rolling dust removing brush 100 are opposite.
That is, the protrusions may be formed of regularly or irregularly arranged stitches 111. Specifically, in some embodiments of the present invention, the plurality of stitches 111 may be divided into a plurality of stitch groups 110, and the number of stitches 111 in each group of stitches 111 is the same and is circumferentially arranged along the circumferential side of the dust-removing brush roll 100. The pins 111 in each pin group 110 extend outward from the outer circumferential side surface of the dust-removing drum brush 100 in the same oblique direction (clockwise or counterclockwise as viewed from the cross-section of the dust-removing drum brush 100). Further, the inclination directions of the stitches 111 in the two adjacent stitch groups 110 are different, that is, the plurality of stitches 111 in the two adjacent stitch groups 110 cross each other when viewed from the cross section of the dust removing roller brush 100. From this, the setting of crisscross slope can be realized to a plurality of stitches 111 of arranging along the axial of dust removal round brush 100, and after dust removal round brush 100 contact filter screen 600 and pushed the mesh with the dust, a plurality of stitches 111 accessible and the different effort of direction that the mesh of filter screen 600 produced break away from the mesh more smoothly, and then make cleaning device 1's cleaning operation more smooth and easy.
In other embodiments of the present invention, the protrusions may be configured in other configurations having rugged surfaces.
In some embodiments of the present invention, the sweeping device 1 further includes a dust collecting comb 300 and a dust removing shaft 400.
Figure 7b is a schematic, partially enlarged view of the collection comb 300 of figure 6 showing the base plate 310 and the comb teeth 320.
The dust collecting comb 300 may be mounted on the dust collecting case 900 to be disposed under the dust collecting case in parallel with the adsorption drum brush 200 and above the opening of the dust collecting case 900, referring to fig. 7b, the dust collecting comb 300 has a plurality of comb teeth 320 and is configured to scrape off and collect the dust adsorbed to the adsorption drum brush 200 on the plurality of comb teeth 320. Specifically, the dust collection comb 300 may have a base plate 310 and be configured to be disposed under and behind the adsorption drum brush 200 in a lateral direction, and the plurality of comb teeth 320 extend upward and bent forward from the upper surface of the base plate 310 toward the adsorption drum brush 200 such that at least part of the tooth heads of the plurality of comb teeth 320 are kept in contact with at least part of the adsorption drum brush 200.
In some embodiments of the present invention, the dirt-collecting comb 300 can be configured to be fixed inside the indoor unit, for example, to a mounting base of the cleaning device or to the casing 2 or skeleton of the indoor unit. That is, the adsorption drum brush 200 positioned at the upper side of the dust collecting comb 300 is controlled to roll so that the dust adsorbed thereon is scraped off by the comb teeth 320 of the dust collecting comb 300 positioned therebelow and fixedly disposed. The dust collecting comb 300 further may directly block the scraped dust in the gaps between the plurality of comb teeth 320. Therefore, the dust is transferred from the adsorption roller brush 200 to the dust collection comb 300, and the dust does not fly during the transfer, and the adsorption roller brush 200 scraped clean by the dust collection comb 300 can continuously adsorb the dust pushed out by the dust removal roller brush 100.
In some embodiments of the present invention, the dust removing shaft 400 may be configured to be rotatably mounted on the dust box 900 above the opening of the dust box 900 and disposed below the dust collecting comb 300 in parallel. The dust removing shaft 400 is controlled to rotate to scrape off dust on the dust collecting comb 300 and to push the scraped dust into an opening of the dust box 900. The dust collecting case 900 may be a separately provided case body, or may be provided as a mounting base of the cleaning apparatus 1 and include a case body for collecting dust (to be described in detail later).
