[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be noted that the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0029] The present invention provides an air conditioner indoor unit, which specifically relates to a wall-mounted air conditioner indoor unit. The air conditioner indoor unit can be a cooling unit or a cooling and heating unit. The following mainly describes an air conditioner indoor unit having both a cooling mode and a heating mode.

[0030] In the embodiment of the present invention, Figures 1 to 3 As shown, the air conditioner indoor unit includes: a dust box 10, the dust box 10 has an opening; a roller brush 20, which is rotatably arranged on the dust box 10, and the rotation axis of the roller brush 20 extends along the length direction of the opening of the dust box 10; a filter assembly, including a rotating shaft 30 and a filter that can be movably arranged around the rotating shaft 30, and the moving track of the filter passes through the opening of the dust box 10, so that the roller brush 20 cleans the filter in the cleaning mode of the air conditioner; a dust removal part 40, disposed below the roller brush 20, the dust removal member 40 includes an upper comb-shaped portion 41, the upper comb-shaped portion 41 has dust removal teeth 42 abutting against the roller brush to remove dust on the roller brush when the roller brush 20 rotates; the grille 50, disposed below the dust removal member 40, the grille 50 includes a lower comb-shaped portion 51, the lower comb-shaped portion 51 has dust filter teeth 52, and the upper comb-shaped portion 41 and the lower comb-shaped portion 51 are disposed on opposite sides of the rotation axis.

[0031] In this embodiment, the air conditioner indoor unit includes a shell, which is used to form the overall appearance of the air conditioner indoor unit. The shell includes a chassis, a face frame and a panel. The shell is provided with an air inlet, which can be provided at the top of the shell. An air duct is formed inside the shell. The shell is also provided with a heat exchanger assembly and a fan. External air enters the shell from the air inlet, and is blown out through the air outlet under the action of the fan after heat exchange by the heat exchanger. The position of the air outlet is not limited. For example, the air outlet is provided on the front panel of the shell. It only needs to satisfy that the air outlet is connected to the air duct so that the wind in the air duct can be blown out from the air outlet.

[0032] The dust box 10 is arranged at one end in the length direction of the air inlet, and the filter can be movably laid on the air inlet. In the cleaning mode of the air conditioner, the filter moves around the rotating shaft 30 to move relative to the roller brush 20, so that different parts of the filter can contact the roller brush 20, so that the dust on the filter can be effectively brushed off by the roller brush 20, and the filter plays a self-cleaning role. The circumference of the rotating shaft 30 can be provided with winding teeth, and the two sides of the filter can be provided with winding racks adapted to the winding teeth. The roller brush 20 is arranged parallel to the rotating shaft 30. When the rotating shaft 30 rotates to drive the filter to move, and the roller brush 20 also rotates, the roller brush 20 will clean the filter. The roller brush 20 includes a roller and bristles arranged on the roller. The roller is arranged adjacent to the active track of the filter so that the bristles pass through the active track of the filter as the roller rotates. The roller can be arranged away from the rotating shaft 30, as long as the filter passes through the roller during the movement. There is no restriction on the material of the bristles, and the bristles and the filter will contact each other during the movement, so that the bristles can brush off the dust on the filter to achieve the purpose of cleaning the filter.

[0033] The opening of the dust box 10 faces upward and extends along the front-to-back direction of the air conditioner indoor unit. After the roller brush 20 moves and contacts the filter, the dust on the filter will fall directly into the dust box 10, and part of it will adhere to the roller brush 20. The dust removal member 40 is installed in the dust box 10, the upper comb-shaped part 41 abuts against the inner wall of the dust box 10, and the dust removal teeth 42 are protruding from the upper comb-shaped part 41 and form a dust passing gap with the other inner wall of the dust box 10. After the roller brush 20 contacts the dust removal teeth 42, the dust on the roller brush 20 will be brushed off by the dust removal teeth 42 and fall into the dust box 10 through the dust passing gap. The grille 50 is installed in the dust box 10, the lower comb-shaped part 51 is in contact with the inner wall of the dust box 10, the filter teeth 52 are protruding from the lower comb-shaped part 51, and a through hole is formed between the lower comb-shaped part 51 and the other inner wall of the dust box 10. The dust is stored at the bottom of the dust box 10 through the through hole, and the hair is entangled with the filter teeth 52, thereby effectively filtering and storing the hair ash. The upper comb-shaped part 41 and the lower comb-shaped part 51 are located on opposite sides of the rotation axis in the horizontal direction, and the lower comb-shaped part 51 can effectively avoid the sedimentation trajectory of the hair ash, so that the hair ash can fall smoothly to the bottom of the dust box 10. In actual application, the dust box 10 can be used to hold water, and the roller brush 20 is at least partially located below the liquid surface to improve the cleaning quality of the roller brush 20 on the filter screen.

[0034] The air-conditioning indoor unit of the present invention arranges the upper comb-shaped portion 41 and the lower comb-shaped portion 51 on opposite sides of the rotation axis of the roller brush 20, so that the dust on the roller brush 20 can be smoothly dropped to the grille 50 after being screened by the dust removal teeth 42, and is concentrated at the bottom of the dust collecting box 10 through the grille 50. In this way, the dust can be prevented from accumulating on the dust removal component 40 to hinder the rotation of the roller brush 20, thereby improving the self-cleaning effect of the air-conditioning indoor unit.

[0035] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0036] In one embodiment, on the side of the roller brush 20 away from the open dust box 10, the roller brush 20 rotates from the side away from the upper comb-shaped part 41 to the side close to the upper comb-shaped part 41. In this embodiment, the side of the roller brush 20 away from the open dust box 10, i.e., the lower surface of the roller brush 20 below the rotation axis, when the lower surface of the roller brush 20 rotates, the rotation direction is from the side away from the upper comb-shaped part 41 to the side close to the upper comb-shaped part 41, i.e., from the free end of the dust removal teeth 42 to the fixed end of the dust removal teeth 42, thereby increasing the contact area between the roller brush 20 and the dust removal teeth 42, and improving the cleaning effect of the hair dust on the roller brush 20. In addition, since the lower comb-shaped part 51 and the upper comb-shaped part 41 are located on opposite sides of the rotation axis, when the lower surface of the roller brush 20 rotates, it rotates from the side close to the lower comb-shaped part 51 to the side away from the lower comb-shaped part 51. The through hole formed by the grille 50 is located on the side away from the lower comb-shaped portion 51. When the roller brush 20 rotates, part of the dust will fall directly and settle toward the side where the through hole is located under the action of centrifugal force. Therefore, the dust that falls directly can directly fall to the bottom of the dust box 10 through the through hole, which is convenient for storage and improves the dust collection effect of the dust box 10.

[0037] Specifically. Figure 1 As shown, the dust removal teeth 42 extend obliquely from the fixed end toward the opening of the dust box 10. In this embodiment, the fixed end of the dust removal teeth 42 is connected to one end of the upper comb-shaped portion 41, and the dust removal teeth 42 extend obliquely toward the opening of the dust box 10, that is, extend obliquely upward, thereby increasing the length of the dust removal teeth 42 to increase the contact area between the dust removal teeth 42 and the bristles, and avoiding reducing the width of the dust passing gap to ensure that the brushed dust can fall into the dust box 10.

[0038] In actual application, the line connecting the rotation axis and the fixed end of the dust tooth 42 is set at an angle to the extension direction of the dust tooth 42. In this embodiment, the line connecting the rotation axis and the projection of the fixed end of the dust tooth 42 on the cross section of the roller brush 20 is set at an angle to the extension direction of the dust tooth 42; that is, at the contact portion between the roller brush 20 and the dust tooth 42, the angle between the extension direction of the dust tooth 42 and the tangent direction of the roller brush 20 is less than 90 degrees, thereby increasing the contact time of the dust tooth 42 and the bristles in the opposite movement, that is, increasing the effective brushing time of the dust tooth 42 on the roller brush 20, so as to improve the brushing effect on the roller brush 20.

[0039] In one embodiment, if Figure 2 and Figure 3As shown, the number of the dust removal teeth 42 is multiple, and the multiple dust removal teeth 42 are arranged at intervals along the axial direction of the roller brush; the number of the flocculent filtering teeth 52 is multiple, and the multiple flocculent filtering teeth 52 are arranged at intervals along the axial direction of the roller brush. In this embodiment, the specific number of the dust removal teeth 42 is not limited, and the multiple dust removal teeth 42 can effectively increase the contact area with the roller brush 20, thereby improving the dust removal effect on the roller brush 20. The specific number of the flocculent filtering teeth 52 is not limited, and the multiple flocculent filtering teeth 52 can provide more hair for attachment and entanglement, so as to prevent the hair from floating up and attaching to the dust removal member 40, thereby improving the filtering and storage effect of the grille 50.

[0040] Specifically, Figure 2 and Figure 3 As shown, the distribution density of the plurality of dust removal teeth 42 is greater than the distribution density of the plurality of lint-filtering teeth 52. In this embodiment, the distribution density of the dust removal teeth 42 is relatively large, that is, the gaps between adjacent dust removal teeth 42 are relatively small, so as to increase the contact area between the dust removal teeth 42 and the bristles, and improve the dust removal effect on the roller brush 20. The distribution density of the lint-filtering teeth 52 is relatively small, that is, the gaps between adjacent lint-filtering teeth 52 are relatively large, so as to increase the cross-sectional area of ​​the through hole, so that more ash can fall into the bottom of the dust box 10 more smoothly, and improve the filtering and storage effect of the grille 50.

[0041] In practical applications, such as Figure 1 and Figure 2 As shown, the rotating shaft 30 is located at the open end of the dust box 10 and above the roller brush 20. In this embodiment, a cleaning gap is formed between the rotating shaft 30 and the roller, and the moving tracks of the filter screen and the bristles pass through the cleaning gap, so that the bristles can effectively clean the filter screen. The rotating shaft 30 is located at the open end of the dust box 10, which can make the overall structure of the rotating shaft 30 and the dust box 10 simpler and more compact, thereby reducing the space occupied by the roller and improving the stability of the structure.

[0042] In one embodiment, the rotation direction of the rotating shaft 30 is opposite to the rotation direction of the roller brush 20. In this embodiment, the movement direction of the filter is opposite to the rotation direction of the bristles, which can increase the relative movement speed of the filter and the bristles, thereby increasing the brushing force of the bristles on the filter, so as to improve the cleaning effect of the roller brush 20 on the filter. Specifically, the rotation speed of the rotating shaft 30 can be less than the rotation speed of the roller, so as to increase the brushing frequency of the bristles on the same position of the filter, thereby improving the cleaning quality of the filter. It can be understood that the air conditioner indoor unit also includes a first drive motor and a second drive motor, the first drive motor drives the roller brush 20 to rotate, and the second drive motor drives the rotating shaft 30 to rotate, so as to realize the automatic rotation of the rotating shaft 30 and the roller brush 20, thereby realizing the self-cleaning process of the air conditioner indoor unit.

[0043] In practical applications, such as Figure 1As shown, the free end of the dust removal tooth 42 does not protrude from the rotation axis, and the free end of the flocculent filter tooth 52 protrudes from the rotation axis. In this embodiment, the projection of the free end of the dust removal tooth 42 on the cross section of the dust box 10 does not protrude from the rotation axis, so that the dust clearance gap formed between the dust removal tooth 42 and the inner wall of the dust box 10 has a sufficient width to ensure that hair can pass smoothly. The projection of the free end of the flocculent filter tooth 52 on the cross section of the dust box 10 protrudes from the rotation axis, so that the flocculent filter tooth 52 has a sufficient length for hair to be effectively wrapped around and to block the dust accumulated at the bottom of the dust box 10.

[0044] The present invention also provides an air conditioner, which includes an air conditioner outdoor unit and an air conditioner indoor unit. The specific structure of the air conditioner indoor unit refers to the above embodiment. Since the air conditioner adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the air conditioner indoor unit and the air conditioner outdoor unit are connected by a refrigerant pipe.

[0045] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
