[0002] Currently, the filters in air conditioner indoor units are mainly cleaned manually, but most consumers often forget to clean them, resulting in a large amount of dust accumulating on the filters. This not only reduces the air intake of the indoor unit, thereby increasing power consumption, but also causes secondary pollution to the indoor air quality. Based on the above-mentioned shortcomings, the prior art has proposed to provide corresponding automatic cleaning components, such as roller brushes, in the air conditioner indoor unit to automatically clean the filters in the air conditioner indoor unit. However, the current filters are separately provided for the air inlet or fresh air inlet of the air conditioner indoor unit, making it difficult to clean filters in different positions at the same time. Furthermore, providing cleaning components for filters in different positions will occupy a larger air conditioning space and increase the manufacturing cost of the air conditioner. Summary of the Invention

[0003] Therefore, the present invention provides an air conditioner indoor unit and an air conditioner with a fresh air function, which can overcome the deficiency in the related art that filters at different positions cannot be automatically cleaned at the same time.

DETAILED DESCRIPTION

[0020] See also Figures 1 to 3 As shown, the present invention provides an air conditioner indoor unit with a fresh air function, comprising an indoor unit body 100 having an indoor air inlet 11 and an outdoor fresh air inlet 12, a filter 2, and a cleaning assembly 3. The filter 2 has a first filter area 21 corresponding to the indoor air inlet 11 and a second filter area 22 corresponding to the outdoor fresh air inlet 12. The cleaning assembly 3 is disposed adjacent to the filter 2 to enable cleaning of the filter 2. In this technical solution, the filter 2 has both the first filter area 21 and the second filter area 22. When cleaning the filter 2 is required, only one side needs to be cleaned, thereby cleaning both the first filter area 21 and the second filter area 22 in a single cleaning process. There is no need to separately provide corresponding cleaning assemblies 3 for the two filter areas, thereby reducing the internal space occupied by the air conditioner indoor unit and lowering the manufacturing cost of the air conditioner.

[0021] The air conditioner indoor unit with a fresh air function also includes a guide rail housing 4. The filter 2 is located within the guide rail housing 4 and can slide along the guide direction of the guide rail housing 4, so that the filter 2 can slide from the filter area corresponding to the indoor air inlet 11 and the outdoor fresh air inlet 12 to the outside of the filter area, or from the outside of the filter area to the filter area. The sliding method allows the filter 2 to switch positions within the guide rail housing 4. The structure is simple and compact, while also ensuring the reliable and stable position switching of the filter 2. The guide rail housing 4 can specifically be composed of a bottom shell 41 at the bottom and a cover shell 42 at the top, which are assembled into a whole to more conveniently accommodate the filter 2 therein. It is understood that the guide rail housing 4 is constructed with ventilation areas corresponding to the indoor air inlet 11 and the outdoor fresh air inlet 12, respectively. When the filter 2 is in the working position, the first filter area 21 and the second filter area 22 of the filter 2 correspond to the ventilation areas, respectively.

[0022] As a specific embodiment of the cleaning component 3, the cleaning component 3 includes a first drum component and a roller brush 32 arranged adjacent to it. The first drum component includes a first drum 31 and a first rotary drive member 33 that drives it to rotate. The first drum 31 is connected to one end of the filter screen 2 and can completely wind the filter screen 2 to the outer peripheral side of the first drum 31. The filter screen 2 can be completely rolled up or unrolled through the first drum 31, thereby ensuring that the filter screen 2 can be cleaned more comprehensively and thoroughly by the roller brush 32.

[0023] Preferably, the cleaning component 3 is also provided with a dust box 34, which is constructed with a dust collection inlet that allows the dust swept by the roller brush 32 to enter. A corresponding dust height detection sensor can be set therein to detect the dust accumulation height in the dust box 34. When the height reaches a preset height, the corresponding controller can issue a corresponding prompt message to remind the user to deal with it in time.

[0024] In some embodiments, dust removal teeth 35 are provided adjacent to the roller brush 32, and the tooth tops of the dust removal teeth 35 are in contact with the roller brush 32 so that dust attached to the surface of the roller brush 32 can be removed and dropped into the dust collection box 34 during the rotation of the roller brush 32; preferably, the dust removal teeth 35 are provided on the inner wall of the dust collection box 34 to simplify the structural design, and better, the dust removal teeth 35 can be integrally formed with the dust collection box 34.

[0025] Preferably, the first end of the filter 2 is connected to the first reel 31, and the second end of the filter 2 is connected to the first end of the traction member 51. The traction member 51 can be used to switch the position of the filter 2. Specifically, the filter 2 wound on the first reel 31 is pulled to positions corresponding to the indoor air inlet 11 and the outdoor fresh air inlet 12. This process can be called unwinding. The air conditioner indoor unit with fresh air function also includes a second reel assembly, which includes a second reel 52 and a second rotary drive member 53 that drives the second reel to rotate. The second reel 52 is connected to the second end of the traction member 51 and can be wound around its outer periphery, so that the unwinding process of the filter 2 can also be automated, making it easier for the user to clean the filter 2. The traction member 51 can be, for example, a winding rope or a coiled spring.

[0026] In some embodiments, a roller 6 is further provided on the sliding path of the filter 2 to support the filter 2 thereon and ensure smooth sliding of the filter 2. The roller 6 can be rotatably connected to the inner machine body 100, and preferably can be rotatably connected to the guide rail housing 4.

[0027] As a specific implementation method, Figure 1As shown, the indoor air inlet 11 of the air conditioner indoor unit is arranged at the top position of the indoor unit body 100, and the opening of the indoor air inlet 11 is upward, so as to prevent it from directly facing the user and destroying the overall aesthetics of the air conditioner indoor unit, and the outdoor fresh air inlet is arranged at the end position of one side of the indoor unit body 100 to facilitate its connection with the external space.

[0028] like Figure 3 As shown, the indoor unit body 100 also has an outdoor fresh air outlet 103, and the filter 2 also has a third filter area 23 corresponding to the outdoor fresh air outlet 103. It should be noted that since the outdoor fresh air outlet 103 is also arranged at the top position of the indoor unit body 100, the provision of the third filter area 23 can prevent dust in the air from entering the corresponding fresh air duct through the outdoor fresh air outlet 103.

[0029] The specific design of the filter 2 can be varied. For example, the filter 2 can be formed by injection molding a filter mesh material and a filter frame, or the filter frame can be sewn together with a fabric, or the mesh material and the frame can be welded together. Preferably, the filter 2 is a flexible filter mesh that is bendable and foldable so that it can be smoothly wound onto the first reel 31; and / or the filter 2 has a thickness of 0.5 mm to 2 mm to ensure sufficient structural strength.

[0030] Preferably, a dust detection sensor is provided at the fresh air component, which can detect the amount of dust accumulated in the fresh air component. When the thickness exceeds a preset value, a reminder message is sent through the corresponding controller to remind the user to use the dust removal function to clean the filter 2.

[0031] The following combination Figure 2 The working process of the technical solution of the present invention is further explained.

[0032] When the filter self-cleaning is turned on (the user can issue a corresponding instruction, or the controller can determine and issue a corresponding instruction), the left reel (i.e., the first reel 31) rotates counterclockwise, driving the integrated filter 2 to move in the guide rail (i.e., the guide rail housing 4), and the right reel (i.e., the second reel 52) rotates counterclockwise, causing the filter to drive the winding rope (i.e., the traction member 51) to move to the left, and the filter at the fresh air component (i.e., the high-efficiency filter assembly 101) slides and turns from the guide rail of the fresh air component, and the left reel reels the filter 2, and the left roller brush 32 rotates counterclockwise to clean the dust on the filter 2. When the winding rope has reached its limit length, the left reel stops rewinding, the right reel stops releasing the winding rope, and the filter 2 stops moving. After cleaning, the left reel rotates clockwise to release the filter 2, and the right reel rotates counterclockwise to rewind the winding rope, and finally stops after reaching the initial position. At this point, the air conditioner has achieved self-cleaning of the dust removal filter inside the entire machine, while improving the filtration efficiency of the fresh air filter and extending the service life of the fresh air HEPA filter.

[0033] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
