The present disclosure provides a guiding rail structure 3, detachably connected to a face frame assembly 100. In the present disclosure, the face frame assembly 100 includes a face frame 1. The face frame 1 may automatically clean the filter screen air conditioner or manually clean the filter screen air conditioner. Specially, the face frame 1 has a frame structure or a cover structure, and the face frame 1 includes an air inlet 11, and the face frame assembly 100 further includes an air inlet grille 2, and the air inlet grille 2 is disposed near the air inlet 11. The air inlet grille 2 and the face frame 1 may also be arranged separately, that is, the air inlet grille 2 is detachably connected to the air inlet 11 of the face frame 1, for example, a detachable connection manner such as a snap connection, a plug fit, a screw connection, or a pin connection is used, which is not limited herein.
Referring to FIG. 1, FIG. 2, FIG. 3, FIG. 5, FIG. 6, FIG. 8, FIG. 9 and FIG. 10, in the embodiments of the present disclosure, the guiding rail structure includes a connecting member 31, a first guiding member 32, and a second guiding member 33. The first guiding member 32 is disposed on at least one side of the connecting member 31, and one end of the first guiding member 32 is arc-shaped. The second guiding member 33 is disposed on at least one side of the connecting member 31 and facing the arc end of the first guiding member 32. The second guiding member 33 and the first guiding member 32 are cooperated with the connecting member 31 to form a sliding rail 34, and the guiding rail structure 3 is detachably connected to the face frame 1.
It should be understood that the detachable connection manner of the guiding rail structure 3 and the face frame 1 may be a snap connection, a plug fit, a screw connection or a pin connection. That is, the guiding rail structure 3 is detachably connected to the face frame 1 through the connecting member 31 and/or the first guiding member 32 and/or the second guiding member 33. The connecting member 31 and the first guiding member 32 and the second guiding member 33 as a whole are detachably connected to the face frame 1. In the present embodiment, the connecting member 31 may be a plate-like structure or a block-like structure, and the connecting member 31 functions as a mounting, fixing, supporting, and connecting. When the guiding rail structure 3 is mounted on the face frame 1, in order to prevent the connecting member 31 from affecting the amount of air entering the air inlet 11, optionally, the connecting member 31 is a plate-like structure. At the air inlet 11 of the face frame 1, the extending direction of the connecting member 31 is the same as the air inlet direction of the air inlet 11. That is, the thickness direction of the connecting member 31 is perpendicular to the air inlet direction.
Specially, in order to match the shape of the guiding rail structure 3 with the shape of the air inlet 11 of the face frame 1, the shape contour of the connecting member 31 is the same as that of the air inlet 11 of the face frame 1, that is, when the guiding rail structure 3 is mounted in the air inlet 11 of the face frame 1, the connecting member 31 is abutted against the inner wall of the face frame 1 and/or the air inlet grille. In order to facilitate the installation of the filter screen 500, a mounting space is defined between the first guiding member 32 and the inner wall of the face frame 1 and/or the air inlet grille. When the filter screen 500 is received in the mounting space, both sides of the filter screen 500 may be abutted against the first guiding member 32, the inner wall of the face frame 1 and/or the air inlet grille.
It should be understood that one end of the first guiding member 32 is arranged in an arc shape, which is advantageous for the same contour shape as the inner wall of the face frame 1 and/or the air inlet grille, such that the mounting of the guiding rail structure 3 to the air inlet 11 of the face frame 1 does not affect the installation of other components of the air conditioner. In order to smoothly install the filter screen 500 in the mounting space, the second guiding member 33 is facing the arc end of the first guiding member 32, the second guiding member 33 and the first guiding member 32 are cooperated with the connecting member 31 to form the sliding rail 34. This facilitates the movement of the filter screen 500 into or out of the mounting space through the sliding rail 34, thereby improving the installation efficiency.
In the present embodiment, the arc-shaped structure of the second guiding member 33 is similar to the arc-shaped structure of the first guiding member 32, that is, the second guiding member 33 has the same bending curvature as the first guiding member 32, that is to say, the distance between the respective corresponding points between the second guiding member 33 and the first guiding member 32 is constant or substantially constant. It should be understood that the arrangement of the second guiding member 33 is advantageous for guiding the filter screen 500. During the installation of the filter screen 500 in the mounting space, the filter screen 500 is prevented from being caught or caught at the bent corner of the face frame 1.
In the present embodiment, depending on the different mounting position of the guiding rail structure 3 at the air inlet 11 of the face frame 1, the number of the first guiding member 32 and the second guiding member 33 disposed on the opposite side surfaces of the connecting member 31 is different. As shown in FIG. 1, FIG. 5 and FIG. 9, when the guiding rail structure 3 is installed in the middle of the air inlet 11 of the face frame 1, the two first guiding members 32 are respectively disposed on opposite sides of the connecting member 31, and the two second guiding members 33 are respectively disposed on opposite sides of the connecting member 31. At this time, the first guiding member 32 on one side of the connecting member 31 and the first guiding member 32 on the other side are disposed correspondingly, the second guiding member 33 on one side of the connecting member 31 and the second guiding member 33 on the other side are disposed correspondingly. As shown in FIG. 2, FIG. 3, FIG. 6, FIG. 8 and FIG. 10, when the guiding rail structure 3 is mounted at the left end or the right end of the air inlet 11 of the face frame 1, the first guiding member 32 and the second guiding member 33 are disposed on only one side of the connecting member 31.
In the present embodiment, one guiding rail structure 3, two guiding rail structures 3 or three guiding rail structures 3 are detachably mounted in the air inlet 11 of the face frame 1. It can be understood that when the one guiding rail structure 3 is detachably mounted in the air inlet 11 of the face frame 1, a first guiding member 32 and a second guiding member 33 are disposed on opposite side surfaces of the connecting member 31 of the guiding rail structure 3, that is, the opposite side surfaces of the connecting member 31 are both formed with a sliding rail 34. At this time, the left end or the right end of the air inlet 11 on the face frame 1 is formed with a filter screen sliding rail integrally disposed on the face frame 1. The filter screen sliding rail is cooperated with the sliding rail 34 to mount the filter screen 500. When the two guiding rail structures 3 are detachably mounted in the air inlet 11 of the face frame 1, that is, the guiding rail structure 3 is mounted at the left end and the right end of the air inlet 11 of the face frame 1, one side surface of the connecting member 31 in each of the guiding rail structures 3 is provided with a first guiding member 32 and a second guiding member 33. At this time, the sliding rails 34 of the two guiding rail structures 3 are oppositely disposed, and the two sliding rails 34 of the two guiding rail structure 3 opposite to each other are cooperated with the filter screen 500. When the three guiding rail structures 3 are detachably mounted in the air inlet 11 of the face frame 1, as shown in FIG. 4 and FIG. 7, the middle, left end and right end of the air inlet 11 of the face frame 1 are all provided with the guiding rail structure 3. The opposite side surfaces of the connecting member 31 of the guiding rail structure 3 mounted at the middle of the air inlet 11 of the face frame 1 is provided with a first guiding member 32 and a second guiding member 33, that is, the opposite side surfaces of the connecting member 31 are both provided with the sliding rails 34. The opposite side surfaces of the connecting member 31 of the guiding rail structure 3 mounted at the left end and the right end of the air inlet 11 of the face frame 1 is provided with a first guiding member 32 and a second guiding member 33. At this time, the sliding rail 34 of the guiding rail structure 3 mounted at the left end of the air inlet 11 of the face frame 1 is cooperated with the sliding rail 34 on the side of the connecting member 31 of the guiding rail structure 3 mounted at the middle of the air inlet 11 of the face frame 1 to mount the filter screen 500, and the sliding rail 34 of the guiding rail structure 3 mounted at the right end of the air inlet 11 of the face frame 1 is cooperated with the sliding rail 34 on the another side of the connecting member 31 of the guiding rail structure 3 mounted at the middle of the air inlet 11 of the face frame 1 to mount the filter screen 500, thereby reducing the length of the filter screen 500, and avoiding the problem that the filter screen 500 is too long to cause inconvenience for disassembly and assembly.
The guiding rail structure 3 of the present disclosure is applied to the face frame 1, by providing the guiding rail structure 3 as a separate component that is detachably mounted on the face frame 1, the face frame 1 manufactured by the same face frame 1 mold can be set as an automatic cleaning filter screen air conditioner or as a manual cleaning filter screen air conditioner, improving the utilization rate and production efficiency of the face frame 1 mold, simplifying the production process, and reducing the production cost. In an embodiment, the guiding rail structure 3 includes a connecting member 31, a first guiding member 32, and a second guiding member 33. The first guiding member 32 is facing the second guiding member 33, and the first guiding member 32 is cooperated with the second guiding member 33 to form the sliding rail 34. When the guiding rail structure 3 is mounted on the face frame 1, it is advantageous for mounting the filter screen 500 on the face frame 1 or detach the filter screen 500 from the face frame 1 through the sliding rail 34. In an embodiment, the guiding rail structure 3 is detachably connected to the face frame 1 through the connecting member 31 and/or the first guiding member 32 and/or the second guiding member 33, which facilitates the quick and stable disassembly and assembly of the guiding rail structure 3.
In an embodiment, as shown in FIG. 1, FIG. 2 and FIG. 3, in the present embodiment, the first guiding member 32 includes an arc section 321 and an extension section 322 connected to the arc section 321. The second guiding member 33 is facing the arc section 321, and the distance between the second guiding member 33 and the arc section 321 is constant or substantially constant.
It should be understood that the extension section 322 of the first guiding member 32 and the inner wall of the air inlet grille 2 at the air inlet 11 of the face frame 1 define a sliding rail or a mounting space to mount the filter screen 500. The arc section 321 of the first guiding member 32 and the second guiding member 33 are arranged to be cooperated with the shape contour of the face frame 1 to realize the guiding installation of the filter screen 500. That is, the arc section 321 of the first guiding member 32 is cooperated with the second guiding member 33 to form the sliding rail 34. When the filter screen 500 is mounted, the filter screen 500 enters the sliding rail or the mounting space defined by the extension section 322 and the inner wall of the air inlet grille 2 through the sliding rail 34 formed by the cooperation of the arc section 321 and the second guiding member 33; when the screen 500 is disassembled, the filter screen 500 moves out of the sliding rail or the mounting space defined by the extension section 322 and the inner wall of the air inlet grille 2 through the sliding rail 34 formed by the cooperation of the arc section 321 and the second guiding member 33.
In other embodiments, the shape, length structure and contour of the second guiding member 33 are the same as the shape, length structure and contour of the first guiding member 32. Thus, the sliding rail 34 formed between the first guiding member 32 and the second guiding member 33 is directly disposed to mount the filter screen 500. Therefore, the wear of the inner wall of the air inlet 11 of the face frame 1 during the installation of the filter screen 500 can be effectively avoided.
