[0027] See also Figures 1 to 6 As shown, according to an embodiment of the present invention, a reversible air outlet structure is provided, comprising an air outlet housing 1, on which an air outlet 11 is constructed, and also comprising a filter 2 (specifically, for example, a coarse filter, a fine filter, a high-efficiency filter, etc.), wherein the filter 2 is slidably connected to the air outlet housing 1, and a driving connection is formed between the filter 2 and a driving component (not labeled in the figure), and the driving component can drive the filter 2 to switch between a first position and a second position, wherein the first position is a position in which the filter 2 is in the air flow area of ​​the air outlet 11, and the second position is a position in which the filter 2 is outside the air flow area of ​​the air outlet 11. In this technical solution, the filter 2 is designed to have a first position in the air flow area and a second position outside the air flow area, so as to meet the dual requirements of air inlet filtration and low wind resistance of the air outlet of the reversible air outlet, and at the same time, the position of the filter 2 is switched and controlled by the driving component, so that the position switching of the filter 2 is automated.

[0028] A specific example of the sliding connection between the filter element 2 and the air outlet housing 1 is that the air outlet housing 1 has a guide rail 12, and the filter element 2 has a plurality of rollers 21, the plurality of rollers 21 are located in the guide rail 12, and the plurality of rollers 21 are respectively located on two relatively arranged frames of the filter element 2 to form a guide for position switching of the filter element 2, thereby ensuring the reliability of the switching process.

[0029] As a specific embodiment of the driving component, preferably, the driving component includes an electric hoisting device 31 and a first rope 32 and a second rope 33 wound on the output shaft of the electric hoisting device 31, wherein the first rope 32 and the second rope 33 respectively have free ends connected to the filter element 2, wherein the first rope 32 can pull the filter element 2 to move in a first direction under the action of the electric hoisting device 31, and the second rope 33 can pull the filter element 2 to move in a second direction under the action of the electric hoisting device 31, and the first direction is opposite to the second direction, that is, when the first rope 32 and the output shaft are in a winding action, the second rope 33 and the output shaft are in a loosening action, thereby ensuring the realization of the first direction and the second direction at the same time. It can be understood that the first rope 32 and the second rope 33 are ropes with a certain strength, such as steel wire ropes. In this technical solution, the first rope 32 and the second rope 33 are wound (or loosened) to make the position selection of the driving component in the air conditioner (in the air outlet structure) more flexible, which is conducive to the internal structure optimization design of the reversible air outlet structure. It can be further understood that the first rope 32 and the second rope 33 can be designed in multiple groups according to actual needs, so as to achieve smooth position switching when the filter element 2 is large in size.

[0030] In some embodiments, the filter element 2 has a first end plate 22 and a second end plate 23 that are relatively arranged, which are specifically perpendicular to the two sides of the roller 21. The free end of the first rope 32 is fixedly connected to the first end plate 22, and the free end of the second rope 33 is fixedly connected to the second end plate 23.

[0031] In some embodiments, a first rubber sleeve 34 is sleeved on the outer peripheral side of the first rope 32, and the end of the first rubber sleeve 34 away from the electric winch device 31 is connected to the air outlet housing 1; and / or a second rubber sleeve 35 is sleeved on the outer peripheral side of the second rope 33, and the end of the second rubber sleeve 35 away from the electric winch device 31 is connected to the air outlet housing 1, and the first rubber sleeve 34 and the second rubber sleeve 35 can respectively isolate the first rope 32 and the second rope 33 to prevent damage that may be caused by contact between external components and the first rope 32 or the second rope 33.

[0032] Further, the end of the first rubber sleeve 34 away from the electric hoisting device 31 is connected to the air outlet housing 1 through the first metal sleeve 36; and / or the end of the second rubber sleeve 35 away from the electric hoisting device 31 is connected to the air outlet housing 1 through the second metal sleeve 37. At this time, because when the first rope 32 and the second rope 33 move, the first rubber sleeve 34 and the second rubber sleeve 35 remain stationary, and the rubber sleeve is not easy to be fixed on the housing, the first metal sleeve 36 and the second metal sleeve 37 are fixed on the housing, which can better limit the rubber sleeve from moving.

[0033] Preferably, the reversible air outlet structure further includes an air outlet grille 4, which is located on the side of the filter element 2 away from the air outlet 11. The setting of the air outlet grille 4 can support the filter element 2, thereby improving the structural strength of the filter element 2.

[0034] Furthermore, the air outlet grille 4 has a plurality of buckles 41 on one side away from the filter element 2 , and the second rubber sleeve 35 is buckled into the plurality of buckles 41 to fix the direction of the second rubber sleeve 35 , making the air outlet structure tidier.

[0035] In some embodiments, the air outlet housing 1 has a shielding portion 13 adapted to the second position, and a roller brush 61 is connected to the inner side of the shielding portion 13. When the filter element 2 switches between the first position and the second position, the roller brush 61 can contact the filter element 2 and rotate under the action of the filter element 2. In this technical solution, the roller brush 61 does not need to be provided with a separate rotation drive device, and can clean the filter element 2 only by the relative movement between the roller brush 61 and the filter element 2, thereby reducing the manufacturing cost. Preferably, the contact between the roller brush 61 and the filter element 2 covers the entire width of the filter element 2, so that all parts of the filter element 2 can be effectively cleaned.

[0036] Preferably, a partition 14 is provided between the shielding portion 13 and the air outlet 11 , and the partition 14 can prevent the flying dust generated by the roller brush 61 thereunder when cleaning the filter element 2 from escaping through the air outlet 11 .

[0037] Furthermore, a scraper 62 is also provided on the inner side of the shielding portion 13, and the free end of the scraper 62 is in contact with the roller brush 61. When the roller brush 61 is driven to rotate by the filter element 2, the scraper 62 can scrape out the dirt adhering to the roller brush 61, thereby cleaning the roller brush 61. The scraper 62 is made of metal. Since a heat exchanger 72 is provided on the inner side of the air outlet 11, the scraper 62 is also arranged adjacent to the heat exchanger 72. The scraper 62 made of metal can form condensation when the heat exchanger 72 is cooled, and the condensation can wash the dirt adhering to the scraper 62 and drop it into the water receiving tray 71 below it. The aforementioned water receiving tray 71 is arranged below the roller brush 61 and / or below the heat exchanger 72.

[0038] According to an embodiment of the present invention, there is further provided an air conditioner, comprising an air outlet structure, wherein the air outlet structure is the above-mentioned reversible air outlet structure.
